Additionally, through the deployment of our megawatt and sub-megawatt platform solutions, we can deliver the benefits of clean distributed power generation, including the desirable value stream of thermal energy, and avoid the need for massive, long distance transmission infrastructure and the risks that the traditional transmission grid creates.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:11.5pt;text-align:justify;margin:0pt 2.7pt 0pt 0pt;"><span style="color:#231f20;font-size:11.5pt;margin-right:0pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">See the section below entitled &#8220;Our Markets&#8221; for information regarding our existing and target markets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-weight:bold;visibility:hidden;">&#8203;</span></p><a id="_7ab8919d_18d7_40ea_a37c_d81c959d5087"></a><a id="OurDurableCompetitiveAdvantages"></a><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><b style="color:#231f20;font-weight:bold;text-decoration-color:#231f20;text-decoration-line:underline;text-decoration-style:solid;">Our Durable Competitive Advantages</b></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 5.5pt;"><span style="color:#231f20;font-style:italic;font-weight:bold;margin-left:0pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="color:#231f20;">Given the long history of investment in and deployment of our solutions, we believe we have the following competitive advantages: </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 5.5pt;"><span style="margin-left:0pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:6pt;text-align:justify;margin:0pt;"><span style="font-size:6pt;visibility:hidden;">&#8203;</span></p><table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:27pt;"></td><td style="font-family:'Times New Roman','Times','serif';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">&#9679;</td><td style="padding:0pt;"><b style="color:#231f20;font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:bold;">Intellectual property </b><span style="color:#231f20;font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">that we believe makes new entry to the market challenging</span><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"> and </span><b style="color:#231f20;font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:bold;">a product portfolio </b><span style="color:#231f20;font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">that consists of several proprietary technologies that are attractive based on market economics, not government mandate</span></td></tr></table></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">9</p></div></div></div>

style="color:#231f20;">We made substantial progress in achieving the key initiatives reflected in the &#8220;Transform&#8221; and &#8220;Strengthen&#8221; phases of our strategy in fiscal year 2021. This included raising capital in the equity markets during the fiscal year and the </span>repayment of $82.3 million of debt obligations under our now extinguished credit facility with Orion Energy Partners Investment Agent, LLC and its affiliated lenders and the payment of $21.5 million to satisfy in full our obligations under the terms of the preferred stock of our Canadian subsidiary, FCE FuelCell Energy, Ltd. We ended fiscal year 2021 with an unrestricted cash balance of $432.2 million compared to an unrestricted cash balance of $149.9 million at the end of fiscal year 2020. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">From an operations perspective, we consistently increased our factory production rates during the year in order to meet our backlog requirements and are currently operating at a 45 MW per year annualized production rate on a single production shift. In addition, we continued to build out our generation backlog, with our San Bernardino project reaching commercial operations in the third quarter of our fiscal year and our Groton and LIPA Yaphank projects nearing commercial operations as the date of this report. We also invested in improving fleet performance during the year with additional module deployments and maintenance activities. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">From a research and development perspective, we increased our activities around commercializing our solid oxide platforms and demonstrated higher electrical efficiency hydrogen production with our solid oxide electrolysis platform at our headquarters in Connecticut. Additionally, we continued our joint research with EMRE on fuel cell carbon capture solutions and recently extended our joint development agreement with EMRE through April 2022. We also invested in improvement initiatives with respect to our core molten carbonate technology in response to issues we were seeing in the field. We identified improvement opportunities ranging from improved thermal management by reducing internal temperature to improving the performance of our electrical balance of plant and began to implement design changes to our commercial platforms which are expected to improve overall product performance. Specific to our stack modules, these improvements centered around delivering more uniform temperature distribution within the stack modules with the intent of improving output over the life of the modules to achieve the product&#8217;s expected design life.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Finally, from a human capital perspective, we strengthened our team across the Company and added key leadership positions including a Chief People Officer and a Chief Marketing Officer. Our global headcount stood at 382 employees as of October 31, 2021 compared to 316 employees as of October 31, 2020. With the foundational execution in fiscal year 2021 and growth initiatives planned for fiscal year 2022, we expect to continue to expand our global team. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.25;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="color:#231f20;font-style:italic;font-weight:bold;visibility:hidden;">&#8203;</span></p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">10</p></div></div></div>

However, our platforms do not stop at power delivery as they are designed to go beyond power, delivering hydrogen, carbon separation, water, and thermal energy in various applications. As a result of our platforms&#8217; ability to deliver multiple value streams, we help our customers reduce their emissions on-site without buying remote carbon/environmental offsets. In the future, we plan to commercialize our hydrogen, long-duration energy storage, and carbon capture technologies intended to drive next generation solutions to help customers attain their decarbonization goals. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Our patented products offer a sustainable alternative to traditional internal combustion-based power generation. Traditional power plants create harmful emissions, such as NOx, SOx and particulate matter, that are a serious public health concern and have a direct impact on the communities in which these plants operate. Alternatively, our power platforms use a combustion-free power generation process that is virtually free of pollutants. Our platforms are highly efficient and environmentally friendly products that support the &#8220;Triple Bottom Line&#8221; concept of sustainability, consisting of environmental, social, and economic considerations. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">As an enterprise, we are proud that, in October 2018, we were certified ISO 14001:2015 compliant, having demonstrated the establishment of and adherence to an environmental management system standard. We believe that we are the only fuel cell manufacturer to have received this certification.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10pt 0pt 0pt 0pt;">Our commitment to sustainability is also evident in the design, manufacturing, installation and on-going servicing of our fuel cell power platforms, which are engineered for recycling and re-use. We start with a commitment to sustainability best practices as part of our corporate culture, then apply this core belief to the design, manufacture, installation and servicing of our fuel cell power platforms. For example, when our plants reach the end of their useful lives, we have the capability to refurbish and re-use certain parts and also recycle most of what we cannot re-use. This is a departure from other combustion-based power generation methods that typically produce a significant amount of unrecyclable waste which increases landfill use. The balance of plant (&#8220;BOP&#8221;) is designed to have an operating life of 25-to-30 years, at which time metals such as steel and copper are reclaimed for scrap value.

Hydrogen-based long duration energy storage has the ability to transform the way intermittent resources are supported with combustion energy sources for continuous power. Instead of producing power from fuel and air, a solid oxide fuel cell stack in electrolysis mode splits water into hydrogen and oxygen using supplied electricity. The hydrogen can be stored as compressed gas, creating the ability to produce a virtually limitless supply. When the grid needs to discharge power, the stored hydrogen will be sent back to the same solid oxide stacks, which react it with air to produce power and to regenerate the water, which will be stored for the next cycle. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;background:#00ff00;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Long duration hydrogen-based energy storage can be achieved without the need to add excessive amounts of conventional battery capacity, a capacity that is reliant on rare earth minerals such as Lithium and Cobalt, both of which have supply constraints for broad adoption, require extensive mining and present long-term disposal challenges post-use. Long duration hydrogen-based energy storage is expected to be required at large scale in order to manage the forecasted high penetration of intermittent renewable resources globally, and this water/hydrogen-based approach of our solid oxide fuel cell/solid oxide electrolysis cell/reversible solid oxide fuel cell technology has the potential to be a key enabler of long duration hydrogen-based energy storage.

We plan to continue to grow this portfolio prudently and in a balanced manner, while also selling projects to customers or project investors when selling presents the best value and opportunity for our capital needs or meets the customer&#8217;s desired ownership structure.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">We operate and maintain our project platforms for the life of the project regardless of the ownership structure. For all operating fuel cell platforms not operating under a PPA, customers enter into long-term service agreements with us, some of which have terms of up to 20 years. We report the revenue earned under long-term maintenance and service agreements as Service agreements and license revenues in our Consolidated Statements of Operations and Comprehensive Loss. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><a id="_Hlk90668129"></a><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Internationally, South Korea and Europe have historically been product sale markets for the Company; however, we have not recognized meaningful product sales revenues in these geographies since 2018. Our activities in South Korea have been impacted by our prior dispute with POSCO Energy and, until fiscal year 2021, we moderated our investment in business development in Europe due to limited resources. &#160;Increasing product sales is a focus area for fiscal year 2022 and beyond. &#160;As a result of entering into a settlement agreement with POSCO Energy and its subsidiary, Korea Fuel Cell Co., Ltd. (&#8220;KFC&#8221;), on December 20, 2021 (the &#8220;Settlement Agreement&#8221;), we have confirmed our full access to the South Korean and broader Asian markets for sales of our products and plan to aggressively pursue sales in these markets, which we see as key to our future growth.

We work to continuously improve and mature our products and implement lessons learned into our product designs and manufacturing process subsequent to introduction. We also invest in improvement initiatives with respect to our core molten carbonate technology. Recently, we identified improvement opportunities ranging from improved thermal management by reducing internal temperature to improving the performance of our electrical balance of plant and began to implement design changes to our commercial platforms which are expected to improve overall product performance. As it relates to our fuel cell modules, these improvements centered around delivering more uniform temperature distribution within the stack modules with the intent of improving output over the life of the modules to achieve the product&#8217;s expected design life. Continued extension of design life and output of our modules over time is a core research and development focus. In addition, we are also investing in commercializing technologies such as <span style="background:#ffffff;">carbon capture and separation, REP, solid oxide fuel cells, and solid oxide electrolysis cells for hydrogen production and energy storage as we believe these technologies represent significant future market opportunities. </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10pt 0pt 0pt 0pt;">Company funded research and development is included in Research and development expenses (operating expenses) in our consolidated financial statements.

(owned by Avangrid, Inc., a wholly owned subsidiary of Iberdrola), the Long Island Power Authority (&#8220;LIPA&#8221;) and Southern California Edison. In Europe, utility customers include E.ON Connecting Energies, one of the largest utilities in the world. In South Korea, we are contracted to operate and maintain a 20 MW power plant project (comprised of five SureSource 3000 plants) for Korea Southern Power Company (&#8220;KOSPO&#8221;). </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10.5pt 0pt 0pt 0pt;">Our SureSource power platforms are producing power for a variety of industrial, commercial, municipal and government customers, including manufacturing facilities, pharmaceutical processing facilities, universities, healthcare facilities and wastewater treatment facilities. These institutions expect efficient, clean and continuous power to reduce operating expenses, reduce greenhouse gas emissions and avoid pollutant emissions to meet their sustainability goals, while boosting resiliency and limiting dependence on the distribution grid. CHP applications further support economic and sustainability initiatives by minimizing or avoiding the use of combustion-based boilers for heat. Our SureSource power platforms are unique in their ability to run on biogas. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10.5pt 0pt 0pt 0pt;"><span style="font-style:italic;font-weight:bold;text-decoration-color:#000000;text-decoration-line:underline;text-decoration-style:solid;">Increasing Biogas Application Market Demand</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10.5pt 0pt 0pt 0pt;">With the growing market for anaerobic digestion (the production of biogas from the breakdown of biodegradable materials in the absence of oxygen) and increasingly stringent regulations regarding air quality, we see a growing market opportunity that is perfectly suited for our fuel cell design. SureSource&#160;power platforms operating on biogas are an especially compelling value proposition as they convert a waste product into clean electricity and heat, while reducing or eliminating flaring, which addresses certain economic, environmental justice, and sustainability challenges faced by our customers and the communities in which they operate. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10.5pt 0pt 0pt 0pt;">Biogas is generated by the decay of organic material (i.e., biomass). This decaying organic material releases methane, or biogas. As a harmful greenhouse gas, biogas cannot be released directly into the atmosphere. Flaring creates pollutants and wastes this potential fuel source. Capturing and using biogas as a fuel addresses these challenges and provides a carbon-neutral renewable fuel source. Our patented, proprietary clean-up skid, SureSource Treatment<sup style="font-size:7.5pt;line-height:100%;top:0pt;vertical-align:top;">TM</sup>, provides an economical and reliable system for treating biogas for use on-site at the biogas production facility. Examples of producers of biogas as part of their operations include wastewater treatment facilities, food and beverage processors and agricultural operations. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10.5pt 0pt 0pt 0pt;">Our SureSource power platforms convert this biogas into electricity and heat efficiently and economically. Wastewater treatment facilities with anaerobic digesters are an attractive market for our SureSource solution including the power platform as well as treatment of the biogas. Many wastewater treatment plants currently flare biogas produced in the anaerobic digestion process, emitting NOx, SOx and particulate matter into the atmosphere, which does not meet many air quality regulations. Since our fuel cells operate on the biogas produced by the wastewater treatment process and the heat is used to support daily operations at the wastewater treatment facility, the overall thermal efficiency of these installations is high, supporting economics and sustainability. In addition, the fuel cell does not emit the harmful NOx, SOx and particulate matter that come out of a flare or that would result from the use of traditional combustion-based power generation. The unique chemistry of carbonate fuel cells allows them to use low Btu on-site biogas with no reduction in output or efficiency compared to operation on natural gas. We have developed proprietary biogas cleanup and contaminant monitoring equipment which, combined with the inherent suitability of the carbonate fuel cell chemistry, gives us an advantage in on-site biogas applications. Our SureSource 1500 and SureSource 3000 power platforms were the first systems certified to California Air Resource Board emissions standards under the Distributed Generation Certification Program for operation with on-site biogas within the state of California.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10pt 0pt 0pt 0pt;"><span style="font-style:italic;font-weight:bold;text-decoration-color:#000000;text-decoration-line:underline;text-decoration-style:solid;">Microgrid and resiliency applications</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10pt 0pt 0pt 0pt;">Our fuel cell solutions are also well suited for microgrid applications, either as the sole source of power generation or integrated with other forms of power generation.

For the municipal-based system in Woodbridge, Connecticut owned by UIL Holdings Corporation, under normal operation, the fuel cell supplies power to the grid. If the grid is disrupted, the fuel cell plant will automatically disconnect from the grid and power a number of critical municipal buildings. Heat from this municipal-based fuel cell platform is used by the local high school. Our fuel cell based microgrids have also continued to operate during public safety power shutoffs events in California.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10pt 0pt 0pt 0pt;"><span style="font-style:italic;font-weight:bold;text-decoration-color:#000000;text-decoration-line:underline;text-decoration-style:solid;">Geographic Market Presence and Market Expansion Targets</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:6pt 0pt 0pt 0pt;">We market our products primarily in the United States, Europe and South Korea, and we are also pursuing expanding opportunities in other countries around the world. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.15;padding-top:10pt;text-align:justify;margin:0pt;">We target for expansion and development markets and geographic regions that:</p><div style="margin-top:6pt;"></div><table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.15;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:18.7pt;"></td><td style="font-family:'Times New Roman','Times','serif';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:24.5pt;padding:0pt;">&#8226;</td><td style="padding:0pt;"><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">Benefit from and value clean distributed generation;

This facility also houses our global service center. Our completed modules are conditioned in Torrington and shipped directly to customer sites. We continue to make investments in various manufacturing areas to improve production throughput and annualized production rate. Currently, we are operating at a 45 MW per year annualized production rate on a single production shift. Maximum annualized capacity (module manufacturing, final assembly, testing and conditioning) is 100 MW per year under the Torrington facility&#8217;s current configuration when being fully utilized. The Torrington facility is sized to accommodate the eventual annualized production capacity of up to 200 MW per year with additional capital investment in machinery, equipment, tooling and inventory.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10pt 0pt 0pt 0pt;">We design and manufacture the core SureSource fuel cell components that are stacked on top of each other to build a fuel cell stack. For megawatt-scale power plants, four fuel cell stacks are combined to build a 1.4 MW fuel cell module. To complete the power platform, the fuel cell module or modules are combined with the balance of plant (&#8220;BOP&#8221;). The mechanical BOP processes the incoming fuel such as natural gas or biogas and includes various fuel handling and processing equipment such as pipes and blowers. The electrical BOP processes the power generated for use by the customer and includes electrical interface equipment such as an inverter. The BOP components are either purchased directly from suppliers or the manufacturing is outsourced based on our designs and specifications. This strategy allows us to leverage our manufacturing capacity, focusing on the critical aspects of the power plant where we have specialized knowledge and expertise and possess extensive intellectual property. BOP components are shipped directly to a project site and are then assembled with the fuel cell module into a complete power plant.</p><a id="_Hlk84250304"></a><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:10pt 0pt 0pt 0pt;">The Torrington production and service facility and the Danbury corporate headquarters and research and development facility are ISO 9001:2015 and ISO 14001:2015 certified and our Field Service operation (which maintains the installed fleet of our platforms) is ISO 9001:2015 certified, reinforcing the tenets of our quality management system and our core values of safety, continuous improvement, and commitment to quality, environmental stewardship, and customer satisfaction. Sustainability is promoted throughout our organization. We manufacture SureSource products and manage them through end-of-life using environmentally friendly business processes and practices, certified to ISO 14001:2015. We continually strive to improve how we plan and execute across the entire product life cycle. We maintain a chain of custody and responsibility of our SureSource products throughout the product life cycle and strive for &#8220;cradle-to-cradle&#8221; sustainable business practices, incorporating sustainability in our corporate culture. We utilize &#8220;Design for Environment&#8221; principles in the design, manufacture, installation and servicing of our power platforms. Design for Environment principles aim to reduce the overall human health and environmental impact of a product, process or service, when such impacts are considered across the product&#8217;s lifecycle. &#160;When our platforms reach the end of their useful lives, we can refurbish and re-use certain parts and then recycle most of what we cannot re-use.

Our fuel cell stack raw materials are sourced from multiple vendors and are not considered precious metals. We have a global integrated supply chain with qualified sources of supply, many of which are located locally in the regions in which we have established manufacturing and service operations including Europe and Asia. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.07;text-align:justify;margin:10pt 0pt 0pt 0pt;">Despite a somewhat volatile nickel market and increased pricing pressure on stainless steel direct materials, we have employed strategic inventory purchases and negotiated fixed-price supply contracts which have helped mitigate the impact to our product cost. Primarily driven by the consequential impact of the COVID-19 pandemic, we are also seeing extended shipping lead-times and pricing pressure on transportation and logistics. We have implemented several initiatives to mitigate the effect of these impacts by optimizing domestic supplier shipping volumes, leveraging competition across multiple qualified freight forwarders, establishing selective direct relationships with steamship lines, and aggregating shipments with qualified suppliers.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.07;text-align:justify;margin:10pt 0pt 0pt 0pt;">While we manufacture the fuel cells in our Torrington facility, the electrical and mechanical BOPs are assembled by and procured from several suppliers. All of our suppliers must undergo a stringent and rigorous qualification process. We continually evaluate and qualify new suppliers as we diversify our supplier base in our pursuit of lower costs, security of supply, and consistent quality. We purchase mechanical and electrical BOP components from third party vendors, based on our own proprietary designs.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.07;text-align:justify;margin:10pt 0pt 0pt 0pt;">Assuring the absence of conflict minerals in our power platforms is a continuing initiative. Our fuel cells, including the fuel cell components and completed fuel cell module, do not utilize any 3TG minerals (i.e., tin, tungsten, tantalum and gold) that are classified as conflict minerals. We utilize componentry in the BOP such as computer circuit boards that utilize trace amounts of 3TG minerals. For perspective, total shipments in fiscal year 2020 weighed approximately 1.3 million pounds, of which only 6.0 pounds, or 0.000480%, represented 3TG minerals, so the presence of these minerals is negligible. Our conflict mineral disclosure filed with the Securities and Exchange Commission (&#8220;SEC&#8221;) on Form SD contains specific information on the actions we are taking to avoid the use of conflict minerals.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Overall, as we continue to grow our business, we remain focused on improving quality, increasing the competitive supply landscape, maintaining existing supplier relationships, as well as building strong new key supplier relationships to expand our supply chain options<span style="font-size:12pt;">.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-size:1pt;margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><a id="_0b5ad7da_7eac_4322_b088_e43de06de820"></a><a id="Engineeringprourementandcontrution"></a><a id="ENGINEERING_PROCUREMENT"></a><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.07;text-align:justify;margin:10pt 0pt 0pt 0pt;"><b style="font-weight:bold;text-decoration-color:#000000;text-decoration-line:underline;text-decoration-style:solid;">Engineerin</b><b style="font-weight:bold;text-decoration-color:#000000;text-decoration-line:underline;text-decoration-style:solid;">g, Procurement and Construction</b></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.07;text-align:justify;margin:10pt 0pt 0pt 0pt;">We provide customers with complete turn-key solutions, including development, engineering, procurement, construction, interconnection and operations for our fuel cell projects.

Pricing for LTSAs is based upon the value of service assurance and the markets in which we compete and includes all future maintenance and fuel cell module exchanges. Each model of our SureSource power platform has a design life of 25-to-30 years. The fuel cell modules, with legacy modules having a 5-year cell design life and current production modules having a 7-year cell design life, go through periodic replacement, while the BOP systems, which consist of conventional mechanical and electrical equipment, are maintained over the life of the project.</p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">23</p></div></div></div>

Operations and maintenance is a key driver for power platforms to deliver their projected revenue and cash flows. The service aspects of our business model provide a recurring and predictable revenue stream for the Company. We have committed future production for scheduled fuel cell module exchanges under LTSAs and PPAs through the year which have expiration dates through 2042. The pricing structure of the LTSAs incorporates these scheduled fuel cell module exchanges and the committed nature of this production facilitates our production planning. Many of our PPAs and LTSAs include guarantees for system performance, including electrical output and heat rate. Should the power platform not meet the minimum performance levels, we may be required to replace the fuel cell module with a new or used replacement module and/or pay performance penalties. Our goal is to optimize the power platforms to meet expected operating parameters throughout their contracted service terms.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.07;text-align:justify;margin:10.5pt 0pt 0pt 0pt;">In addition to our service agreements, we provide a warranty for our products against manufacturing or performance defects for a specific period of time. The warranty term in the U.S. is typically 15 months after shipment or 12 months after acceptance of our products. We accrue for estimated future warranty costs based on historical experience.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-size:1pt;margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-size:1pt;margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><a id="_adc08ecd_8288_433d_97dd_4a84fd827749"></a><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="font-size:1pt;margin-bottom:5pt;margin-top:5pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="font-size:1pt;margin-bottom:5pt;margin-top:5pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="font-size:10pt;font-weight:bold;margin-bottom:5pt;margin-top:5pt;text-decoration-line:underline;text-decoration-style:solid;visibility:hidden;">&#8203;</span></p><a id="Competition"></a><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"><b style="font-weight:bold;text-decoration-color:#000000;text-decoration-line:underline;text-decoration-style:solid;">Competition</b></p><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="font-size:10pt;margin-bottom:5pt;margin-top:5pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;">The market for clean energy is highly competitive. Many factors, including government incentives and specific market dynamics, affect how clean energy can deliver outcomes for customers in a given region. While clean energy <span style="background:#ffffff;">often competes against the electric grid, which is readily available to prospective customers and supplied by traditional centralized power plants, including coal, gas, hydro, and nuclear plants</span>, clean energy is increasingly able to compete with the grid and long-distance transmission of electricity in terms of levelized cost of electricity. Clean energy sources that customers may consider beyond our solutions include products such as wind turbines, solar arrays, and hydro facilities, as well as a range of hydrogen and fuel cell solutions from both incumbent and developing competitors.</p><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="font-size:10pt;margin-bottom:5pt;margin-top:5pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="background:#ffffff;">Our platforms are based on a range of technologies and target a variety of applications, each of which have incumbent and developing competitors. Several companies in the U.S. are engaged in fuel cell development, although, to our knowledge, we are the only domestic company engaged in manufacturing and deployment of stationary natural gas or biogas fueled carbonate fuel cells. In addition to different types of stationary fuel cells, some other technologies that compete in the distributed generation marketplace include micro-turbines, turbines, and reciprocating gas engines.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="font-size:10pt;margin-bottom:5pt;margin-top:5pt;visibility:hidden;background:#ffffff;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="background:#ffffff;">Our stationary fuel cell platforms also compete against large scale solar and wind technologies, although we complement the unreliable intermittent nature of solar and wind power with the continuous, reliable power output of our fuel cells. Utility scale solar and wind power require specific geographies and weather profiles, require transmission for utility-scale applications, and require a source of back up capacity for when the sun or wind is not available. They also require a significant amount of land compared to our fuel cell power plants, making it difficult to site megawatt-class solar and wind projects in urban areas, unlike our solutions. While fuel cells emit negligible amounts of NOx, SOx and particulate matter, fuel cells do emit some carbon dioxide when fueled with natural gas or carbon-neutral biogas, but less per kWh compared to other less-efficient systems. In many markets, baseload fuel cells avoid more emissions than wind or solar systems of similar capacity because they operate for many more hours of the day compared to these intermittent resources.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="font-size:10pt;margin-bottom:5pt;margin-top:5pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;">Product development cycles are long and product quality and efficiency are critical to success. Research and development investments are crucial in this business, as are focused intellectual property strategies and protection of such, as new technologies and solutions could make our solutions less competitive. </p><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="font-size:10pt;margin-bottom:5pt;margin-top:5pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;">We continue to invest in exploring new ways of further improving the efficiency and effectiveness of our platforms. Our objective is to continue to improve our competitive position, including innovating in areas like hydrogen and solid oxide, in order to add value for customers looking for clean and renewable energy and to aid in their decarbonization goals.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-size:1pt;margin-bottom:12pt;visibility:hidden;">&#8203;</span></p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">24</p></div></div></div>

Under a PPA, the utility or end-user of the power (and other attributes such as capacity and renewable energy credits) commits to purchase power as it is produced for an extended period of time, typically 10-to-20 years. With the project being retained, electricity, capacity and/or renewable energy credits are recognized monthly over the term of the PPA.

This extension allows for the continuation of research that would enable incorporation of design improvements to our current fuel cell design in order to support a decision to use the improvements in a future demonstration of the technology for capturing carbon at ExxonMobil&#8217;s Rotterdam refinery in the Netherlands and provides additional time to achieve the first milestone under the EMRE Joint Development Agreement.</p><a id="_Hlk90665943"></a><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10pt 0pt 0pt 0pt;"><span style="font-style:italic;font-weight:bold;">License Agreements and Disputes with POSCO Energy; Settlement Agreement</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10pt 0pt 0pt 0pt;">From approximately 2007 through 2015, we relied on POSCO Energy to develop and grow the South Korean and Asian markets for our products and services. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.07;text-align:justify;margin:10.5pt 0pt 0pt 0pt;">Through June of 2020, we recorded license fees and were entitled to receive royalty income from POSCO Energy pursuant to manufacturing and technology transfer agreements entered into with POSCO Energy, including the Alliance Agreement dated February 7, 2007 (and amendments thereto), the Technology Transfer, License and Distribution Agreement dated February 7, 2007 (and amendments thereto), the Stack Technology Transfer and License Agreement dated October 27, 2009 (and amendments thereto), and the Cell Technology Transfer and License Agreement dated October 31, 2012 (and amendments thereto) (collectively, the &#8220;License Agreements&#8221;). The Cell Technology Transfer and License Agreement (&#8220;CTTA&#8221;) provided POSCO Energy with the exclusive technology rights to manufacture, sell, distribute and service our SureSource 300, SureSource 1500 and SureSource 3000 fuel cell technology in the South Korean and broader Asian markets. POSCO Energy built a cell manufacturing facility in Pohang, South Korea which became operational in late 2015, but is no longer operating.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.07;text-align:justify;margin:10.5pt 0pt 0pt 0pt;">In October&#160;2016, the Company and POSCO Energy extended the terms of certain of the License Agreements to be consistent with the term of the CTTA, which was to expire on October&#160;31, 2027. The CTTA required POSCO Energy to pay us a 3.0% royalty on POSCO Energy net product sales, as well as a royalty on scheduled fuel cell module replacements under service agreements for modules that were built by POSCO Energy and installed at plants in Asia under the terms of long-term service agreements (&#8220;LTSAs&#8221;) between POSCO Energy and its customers. Due to certain actions and inactions of POSCO Energy, we have not realized any new material revenues, royalties or new projects developed by POSCO Energy since late 2015. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.07;text-align:justify;margin:10.5pt 0pt 0pt 0pt;">In March 2017, we entered into a memorandum of understanding (&#8220;MOU&#8221;) with POSCO Energy to permit us to directly develop the Asian fuel cell business, including the right for us to sell SureSource solutions in South Korea and the broader Asian market. In June 2018, POSCO Energy advised us in writing that it was terminating the MOU effective July 15, 2018. Pursuant to the terms of the MOU, notwithstanding its termination, we continued to execute on sales commitments in Asia secured in writing prior to July 15, 2018, including the 20 MW power plant installed for KOSPO. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.07;text-align:justify;margin:10.5pt 0pt 0pt 0pt;">In November 2019, POSCO Energy spun-off its fuel cell business into a new entity, Korea Fuel Cell Co., Ltd. (&#8220;KFC&#8221;), without our consent. As part of the spin-off, POSCO Energy transferred manufacturing and service rights under the License Agreements to KFC, but retained distribution rights and severed its own liability under the License Agreements. We formally objected to POSCO Energy&#8217;s spin-off, and POSCO Energy posted a bond to secure any liabilities to us arising out of the spin-off. In September 2020, the Korean Electricity Regulatory Committee found that POSCO Energy&#8217;s spin-off of the fuel cell business to KFC may have been done in violation of South Korean law.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:10pt 0pt 0pt 0pt;">On February 19, 2020, we notified POSCO Energy in writing that it was in material breach of the License Agreements by (i) its actions in connection with the spin-off of the fuel cell business to KFC, (ii) its suspension of performance through its cessation of all sales activities since late 2015 and its abandonment of its fuel cell business in Asia, and (iii) its disclosure of material nonpublic information to third parties and its public pronouncements about the fuel cell business on television and in print media that have caused reputational damage to the fuel cell business, our Company and our products. We also notified POSCO Energy that, under the terms of the License Agreements, it had 60 days to fully cure its breaches to our satisfaction and that failure to so cure would lead to termination of the License Agreements.

Prior to filing the arbitrations, POSCO Energy obtained provisional attachments from the Seoul Central District Court attaching certain revenues owed to us by KOSPO as part of such warranty claims, which delayed receipt of certain payments owed to us. POSCO Energy subsequently sought additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on unspecified warranty claims in an additional amount of approximately $7 million, and additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on its alleged counterclaims in the license termination arbitration described below in an additional amount of approximately $110 million. As of October 31, 2021, outstanding accounts receivable due from KOSPO were $11.2 million. <span style="background:#ffffff;">POSCO Energy posted a bond in the amount of $46&#160;million to secure any damages to us resulting from the attachments.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On June 28, 2020, we terminated the License Agreements and filed a demand for arbitration against POSCO Energy and KFC in the International Court of Arbitration of the International Chamber of Commerce based on POSCO Energy&#8217;s (i) failure to exercise commercially reasonable efforts to sell our technology in the South Korean and Asian markets, (ii) disclosure of our proprietary information to third parties, (iii) attack on our stock price, and (iv) spin-off of POSCO Energy&#8217;s fuel cell business into KFC without our consent. We requested that the arbitral tribunal (a) confirm through declaration that POSCO Energy&#8217;s exclusive license to market our technology and products in South Korea and Asia is null and void as a result of the breaches of the License Agreements and that we had the right to pursue direct sales in these markets, (b) order POSCO Energy and KFC to compensate us for losses and damages suffered in the amount of more than $200 million, and (c) order POSCO Energy and KFC to pay our arbitration costs, including counsel fees and expenses. We retained outside counsel on a contingency basis to pursue our claims, and outside counsel entered into an agreement with a litigation finance provider to fund the legal fees and expenses of the arbitration. In October 2020, POSCO Energy filed a counterclaim in the arbitration (x) seeking approximately $880 million in damages based on allegations that we misrepresented the capabilities of our fuel cell technology to induce POSCO Energy to enter into the License Agreements and failed to turn over know-how sufficient for POSCO Energy to successfully operate its business; (y) seeking a declaration that the License Agreements remained in full force and effect and requesting the arbitral tribunal enjoin us from interfering in POSCO Energy&#8217;s exclusive rights under the License Agreements and (z) seeking an order that we pay POSCO Energy&#8217;s arbitration costs, including counsel fees and expenses.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:10pt 0pt 0pt 0pt;">We discontinued revenue recognition of the deferred license revenue related to the License Agreements in July 2020 given the then-pending arbitrations.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:10pt 0pt 0pt 0pt;">On August 28, 2020, POSCO Energy filed a complaint in the Court of Chancery of the State of Delaware (the &#8220;Court&#8221;) purportedly seeking to enforce its rights as a stockholder of the Company to inspect and make copies and extracts of certain books and records of the Company and/or the Company&#8217;s subsidiaries pursuant to Section 220 of the Delaware General Corporation Law and/or Delaware common law. POSCO Energy alleged that it was seeking to inspect these documents for a proper purpose reasonably related to its interests as a stockholder of the Company, including investigating whether our Board of Directors and management breached their fiduciary duties of loyalty, due care, and good faith. &#160;POSCO Energy sought an order of the Court permitting POSCO Energy to inspect and copy the demanded books and records, awarding POSCO Energy reasonable costs and expenses, including reasonable attorney&#8217;s fees incurred in connection with the matter, and granting such other and further relief as the Court deemed just and proper. On July 9, 2021, the Court issued a post-trial ruling denying POSCO Energy&#8217;s demand to inspect the Company&#8217;s books and records because POSCO Energy lacked a proper purpose. The Court held that the totality of the circumstances, including the fact that this complaint was the seventh legal action POSCO Energy initiated against us within the span of nine months, confirmed that POSCO Energy&#8217;s purpose in initiating the books and records demand and filing the complaint was not proper. As this dispute was resolved by the Court as described above, it did not require resolution pursuant to, and was not part of, the Settlement Agreement described below.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:10pt 0pt 0pt 0pt;">On September 14, 2020, POSCO Energy filed a complaint in the United States District Court for the Southern District of New York (the &#8220;SD Court&#8221;) alleging that we delayed the removal of restrictive legends on certain share certificates held by POSCO Energy in 2018, thus precluding POSCO Energy from selling the shares and resulting in claimed losses in excess of $1,000,000. On September 16, 2021, the SD Court ruled in our favor on a motion for summary judgement dismissing all four counts of POSCO Energy&#8217;s complaint regarding share certificates held by POSCO Energy in 2018, but granted POSCO Energy leave to file an amended complaint. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">27</p></div></div></div>

The Settlement Agreement provides, among other things, that the parties will cooperate in good faith to effect a market transition to us of the molten carbonate fuel cell business in Korea in accordance with the terms and conditions of the Settlement Agreement. To that end, the Settlement Agreement provides that any and all past, current, or potential disputes and claims between us, on the one hand, and POSCO Energy and KFC, on the other, of any nature whatsoever, whether known or unknown, asserted or not asserted, based on actions or omissions of any party on or before the date of Settlement Agreement are fully and finally settled, including such disputes and claims, directly or indirectly, in connection with the legal disputes (other than the books and records dispute which was resolved by the Court) and License Agreements described above, with the exception of (i) an unfiled claim by us in the amount of approximately $1.8 million with respect to certain royalties we believe are owed by POSCO Energy with respect to replacement modules deployed by POSCO Energy at Gyenonggi Green Energy and other sites for which POSCO Energy has not paid royalties, and (ii) an unfiled claim by POSCO Energy in an unknown amount with respect to a series of purchase orders for materials and components which began in 2014 under a supply chain contract, both of which claims remain unsettled. We do not believe the claim by POSCO Energy with respect to purchase orders for materials and components under the supply chain contract has merit and we retain the right to file a counterclaim for damages we believe we have incurred with respect to such supply chain contract. With respect to the attachments described above, the Settlement Agreement provides that, within five days of the date of the Settlement Agreement, POSCO Energy will file an application with the Seoul Central District Court to revoke the attachments. Thereafter, we expect to promptly receive the outstanding KOSPO accounts receivable of approximately $11.2 million held by the Seoul Central District Court.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;background:#ffffff;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;">Under the Settlement Agreement, the parties have also agreed that, within five days of the date thereof, we will&#160;withdraw our objection to the spin-off of KFC from POSCO Energy, and that the License Agreements are not terminated, but instead are deemed to be amended such that POSCO Energy and KFC only have the right (i) to provide maintenance and repair services to PE Group&#8217;s existing customers on existing molten carbonate power generation and thermal projects under LTSAs currently in force as well as LTSAs that have expired and are pending renewal as of the settlement date (collectively, &#8220;Existing LTSAs&#8221;), (ii) to supply replacement modules purchased from us only for their existing customers for existing molten carbonate power generation and thermal projects under Existing LTSAs and (iii) to own, operate and maintain all facilities and factories solely for the purposes set forth in (i) and (ii) above (collectively, the &#8220;Right to Service License&#8221;). POSCO Energy and KFC further agree that, as of the date of the Settlement Agreement, the License Agreements are deemed to be amended such that we exclusively enjoy all rights as to our technology in Korea and Asia, other than the Right to Service License. The Settlement Agreement further provides that the License Agreements will terminate automatically upon sixty days prior written notice to PE Group if (i) we enter into a business collaboration agreement with a Korean company to construct, assemble, manufacture, market, sell, distribute, import, export, install, commission, service, maintain, or repair products incorporating our technology, or otherwise conduct our business, in the Korean market; or (ii) we expand the capacity of our existing Korean entity such as to perform such activities itself. In the event of the termination of the License Agreements, the license granted to PE Group under the Right to Service License will continue notwithstanding the termination of the License Agreements, except that PE Group&#8217;s right to own, operate, and maintain all facilities and factories for the purpose of servicing any orders or requests made by us will terminate. For the avoidance of doubt, pursuant to the terms of the Settlement Agreement, PE Group has no right to manufacture modules or any other product incorporating our technology under the License Agreements as amended, the Right to Service License or otherwise unless requested and authorized by us to do so.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;background:#ffffff;margin:0pt;">&#160;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;">The Settlement Agreement further provides that, in order to service its existing customers under the Existing LTSAs, KFC will place a firm, non-cancelable order for twelve SureSource 3000 modules within two weeks after the date of the Settlement Agreement and an additional firm, non-cancelable order for eight SureSource 3000 modules on or before June 30, 2022, all at a price of $3.0 million per module. In addition, KFC agrees to use commercially reasonable efforts to order fourteen additional SureSource 3000 modules by December 31, 2022, at a price of $3.0 million per module if ordered by such date. If KFC materially breaches the Settlement Agreement by failing to make timely and full payment for the modules for which KFC is required to place orders under the Settlement Agreement and does not cure such material breach within fifteen days of notice of such breach by us, the License Agreements and the Right to Service License granted to PE Group will be terminated. If we materially breach the Settlement Agreement by failing to supply the modules for which KFC is required to place orders under the Settlement Agreement, as long as KFC has made the payment for such modules and has otherwise satisfied its contractual obligations for those modules and such material breach is not cured within sixty days after notice from PE Group, PE Group will have the right to terminate the Settlement Agreement.

The policies that affect our products are not always the same as those imposed on our competitors, and while some policies can make our products less competitive, others may provide an advantage. Certain utility policies may also pose barriers to our installation or interconnection with the utility grid, such as backup, standby or departing load charges that make installation of our products less economically attractive for our customers. Regulatory and legislative support can take the form of policy, incentive programs, and defined sustainability initiatives such as Renewable Portfolio Standards (&#8220;RPS&#8221;).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:10pt 0pt 0pt 0pt;">Various states and municipalities in the U.S. have adopted programs for which our products qualify, including programs supporting self-generation, clean air power generation, combined heat and power applications, carbon reduction, grid resiliency/microgrids and utility ownership of fuel cell projects.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;">Many states in the U.S. have enacted legislation adopting Clean Energy Standards (&#8220;CES&#8221;) or RPS mechanisms. Under these standards, regulated utilities and other load serving entities are required to procure a specified percentage of their total electricity sales to end-user customers from eligible resources according to a set schedule. CES and RPS, and their implementing regulations, vary significantly from state to state, particularly with respect to the percentage of renewable energy required to achieve the state&#8217;s mandate, the definition of eligible clean and renewable energy resources, and the extent to which renewable energy credits (certificates representing the generation of renewable energy) qualify for CES or RPS compliance. Fuel cells using biogas qualify as renewable power generation technology in all of the CES and RPS states in the U.S., and some states specify that fuel cells operating on natural gas are also eligible for these initiatives in recognition of the high efficiency and low pollutants of fuel cells. Most states are introducing legislation or regulations that seek to reduce the consumption of electricity generated using fossil fuels in favor of zero carbon resources. Additionally, utility regulators are looking for non-wire alternatives to build reliability and resiliency to the grid, which also presents a potential opportunity.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.15;text-align:justify;margin:0pt;">In February 2018, the U.S. Congress reinstated the 30% Investment Tax Credit (&#8220;ITC&#8221;) for fuel cells and extended and significantly expanded the existing Carbon Oxide Sequestration Credit. The ITC phased down to 26% in 2020 and was scheduled to phase down to 22% by 2022 and expire in 2023. The reinstatement of the ITC for fuel cells provided equal access to tax incentives for U.S. fuel cell manufacturers when compared to other clean energy solutions. The ITC phase down was extended by two years pursuant to the Consolidated Appropriations Act, 2021 passed by Congress in December 2020 and signed by the President on December 27, 2020, thus extending the 26% ITC until 2022 and the expiration to 2025. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:10pt 0pt 0pt 0pt;">Internationally, South Korea has an RPS to promote clean energy, reduce carbon emissions, and develop local manufacturing of clean energy generation products to accelerate economic growth. The RPS is designed to increase new and renewable power generation to 10% of total power generation by 2023 from 2% when the RPS began in 2012. Twenty-two of the largest power generators are obligated to achieve the RPS requirements in their generation or purchase offsetting renewable energy certificates. Financial penalties are levied by the government for non-compliance. European governments are supportive of hydrogen-based generation and efficient CHP applications. Italy adopted a system to promote energy efficiency with Italian &#8220;White Certificates&#8221; (Energy Efficiency Certificates) that are tradable certificates, for which fuel cells qualify, to promote energy savings expressed in tons of oil equivalent saved. Germany, the United Kingdom and the Netherlands provide tax incentives, grants and waivers of regulatory fees for clean energy installations. Additionally, large energy-intensive industry sectors and the aviation sector in European Union countries above a certain size qualify for the ETS (Emissions Trading Scheme) and are subject to a cap-and-trade requirement for carbon emissions.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">30</p></div></div></div>

Our future ability to obtain such financing could be impaired by a variety of factors, including, but not limited to, the price of our common stock, our lack of available shares and general market conditions.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Our cost reduction strategy may not succeed or may be significantly delayed, which may result in our inability to deliver improved margins.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Our cost reduction strategy is based on the assumption that increases in production will result in economies of scale. In addition, our cost reduction strategy relies on advancements in our manufacturing process, global competitive sourcing, engineering design, reducing the cost of capital and technology improvements (including stack life and projected power output). Failure to achieve our cost reduction targets could have a material adverse effect on our results of operations and financial condition.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">We have debt and finance obligations outstanding and may incur additional debt in the future, which may adversely affect our financial condition and future financial results.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">As of October&#160;31, 2021, our total consolidated debt and finance obligations outstanding (&#8220;indebtedness&#8221;) was $89.3 million ($87.7 million, net of finance costs and debt discounts).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Our ability to make scheduled payments of principal and interest and other required repayments depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flows from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flows, we may be required to adopt one or more alternatives, such as selling assets, restructuring operations, restructuring debt or obtaining additional equity capital on terms that may be onerous or dilutive.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">We may incur additional indebtedness in the future in the ordinary course of business, which could include onerous restrictions on us. If new debt is added to current debt levels, the risks described above could intensify. Our debt agreements contain representations and warranties, affirmative and negative covenants, and events of default that entitle the lenders to cause our indebtedness under such debt agreements to become immediately due and payable.</p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">36</p></div></div></div>

In the event that interest rates rise or there are changes in tax policy, our financial results could be harmed.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-weight:bold;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Rising interest rates may increase our cost of capital. Part of our business strategy is to generate positive cash flows after debt service from our generation operating portfolio. Rising interest rates may have an adverse impact on the cost of debt and thus result in lower cash flows after debt service than we realize today. We also expect that projects we retain in our generation operating portfolio will receive capital from tax equity investors who derive a significant portion of their economic returns through tax benefits. Tax equity investors are generally entitled to substantially all of the project&#8217;s tax benefits, such as those provided by the U.S. investment tax credit (&#8220;ITC&#8221;) and Modified Accelerated Cost Recovery System or bonus depreciation. Our ability to obtain additional financing in the future depends on the continued confidence of financing sources in our business model and the continued availability of tax benefits applicable to our products. If we are unable to enter into tax equity financing agreements with attractive pricing terms, or at all, we may not be able to obtain the capital needed to finance the build out of our generation assets which would impact our overall liquidity and our business, financial condition and results of operations. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Unanticipated increases or decreases in business growth may result in adverse financial consequences for us.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:10pt 0pt 0pt 0pt;">We operate a 167,000 square-foot manufacturing facility in Torrington, Connecticut where we produce the individual cell packages and assemble the fuel cell modules. The maximum annualized capacity (module manufacturing, final assembly, testing and conditioning) is 100 MW per year under the Torrington facility&#8217;s current configuration when being fully utilized. The Torrington facility is sized to accommodate the eventual annualized production capacity of up to 200 MW per year with additional capital investment in machinery, equipment, tooling and inventory.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;">We have a manufacturing and service facility in Taufkirchen, Germany that has the capability to perform final module assembly for up to 20 MW per year of sub-megawatt fuel cell power platforms to service the European market. Our European service activities are also operated out of this location. In addition, we have a research and development facility in Calgary, Alberta, Canada that is focused on the engineering and development of the Company&#8217;s SOFC and SOEC technology. This facility includes equipment for the manufacturing of solid oxide cells and stacks, including an advanced automated stack manufacturing line which has been developed to ensure that the labor and overhead which are required to produce these technologies are optimized for efficiency and complement the low direct material cost of the stack.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">If our business grows more quickly than we anticipate, our existing and planned manufacturing facilities may become inadequate and we may need to seek out new or additional space, or retrofit or further equip our existing facilities, at considerable cost to us. If our business does not grow as quickly as we expect, our existing and planned manufacturing facilities would, in part, represent excess capacity for which we may not recover the cost. In that circumstance, our revenues may be inadequate to support our committed costs and our planned growth, and our gross margins and business strategy would be adversely affected.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"><span style="font-style:italic;font-weight:bold;">We are subject to risks in international operations, including risks pursuant to our settlement agreement with POSCO Energy Co., Ltd.

We have not recognized meaningful product sales revenue to customers located outside the U.S. since 2018. With the recent settlement of our litigation with POSCO Energy and KFC, we expect to make significant product sales into South Korea and, with our renewed emphasis on marketing our products in European markets, we expect to make future product sales there as well. &#160;We have limited experience developing and manufacturing our products to comply with the commercial and legal requirements of international markets. In addition, we are subject to tariff regulations and requirements for export licenses, particularly with respect to the export of some of our technologies. We face numerous challenges in our international expansion, including the strain any future growth may place on management, service and operations teams and financial infrastructure. &#160;We will face risk from complex and changing regulatory requirements, fluctuations in currency exchange rates, accounts receivable requirements and collections, difficulties in managing international operations, potentially adverse tax consequences, restrictions on repatriation of any earnings and the burdens of complying with a wide variety of international laws.

Factors that may be considered a change in circumstances indicating that the carrying value of our goodwill might not be recoverable include a significant decline in projections of future cash flows and lower future growth rates in our industry. We review IPR&amp;D for impairment on an annual basis as of July&#160;31 or more frequently if facts and circumstances indicate the fair value is less than the carrying value. If the technology has been determined to be abandoned or not recoverable, we would be required to record a charge reflecting impairment of the asset. We review inventory and long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. We consider a project asset commercially viable and recoverable if such project asset is anticipated to be sellable for a profit, or generates positive cash flows, in excess of the cost of the project asset once it is either fully developed or fully constructed. If any of our project assets are not considered commercially viable or costs are not deemed to be recoverable, we would be required to record a charge reflecting the impairment of such project assets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-style:italic;font-weight:bold;">Our Advanced Technologies contracts are subject to the risk of termination by the contracting party and we may not realize the full amounts allocated under some contracts due to the lack of Congressional appropriations or early termination.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-style:italic;font-weight:bold;margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">A portion of our revenues has been derived from long-term cooperative agreements and other contracts with the DOE and other U.S. government agencies.

We also rely on third-party suppliers for the BOP components in our products. Suppliers must undergo a qualification process, which takes four to twelve&#160;months. We continually evaluate new suppliers, and we are currently qualifying several new suppliers. There are a limited number of suppliers for some of the key components of our products. In addition, to the extent the processes that our suppliers use to manufacture components are proprietary, we may be unable to obtain comparable components from alternative suppliers, all of which could harm our business prospects, results of operations and financial condition. We do not know whether we will be able to maintain long-term supply relationships with our critical suppliers, or secure new long-term supply relationships on terms that will allow us to achieve our objectives, if at all. A supplier&#8217;s failure to develop and supply components in a timely manner or to supply components that meet our quality, quantity or cost requirements or our technical specifications, or our inability to obtain alternative sources of these components on a timely basis or on terms acceptable to us, could each harm our ability to manufacture our SureSource products. &#160;In addition, our supply chain has been, and may continue to be, adversely affected by the COVID-19 pandemic, which has created global shipping and logistics challenges. These challenges include extended shipping lead times and pricing pressures on transportation and logistics that have adversely impacted, and may continue to adversely impact, our ability to meet our production schedules and project deadlines, may result in additional and increased costs, or may otherwise adversely impact our business, results of operations and financial condition. If we are unable to pass these costs on to our customers or timely complete projects, we may experience reduced revenue and other adverse impacts on our business, results of operations and financial condition. Given that our customers and suppliers are facing similar global supply chain challenges, we expect continued difficulty in forecasting demand and supply needs for the foreseeable future.

These effects could include disruptions to or restrictions on our employees&#8217; ability to travel, as well as temporary or prolonged closures of our facilities or the facilities of our customers, suppliers, or other vendors in our supply chain. In addition, COVID-19 has resulted in a widespread health crisis that has adversely affected, and may continue to adversely affect, the economies and financial markets of many countries, resulting in economic downturns that could affect demand for our products or our ability to obtain financing for our business or projects. COVID-19 may impact the health of our team members, directors or customers, reduce the availability of our workforce or those of companies with which we do business, or otherwise cause human impacts that may negatively impact our business. Any of these events, which may result in disruptions to our supply chain or customer demand, could materially and adversely affect our business and our financial results. The extent to which COVID-19 will impact our business and our financial results will depend on future developments, which are highly uncertain and cannot be predicted. </p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">39</p></div></div></div>

For example, on March&#160;18, 2020, in response to the escalating global COVID-19 outbreak, we temporarily suspended operations at our Torrington, Connecticut manufacturing facility, and also ordered those employees that could work from home to do so. We resumed operations in the manufacturing facility on June&#160;22, 2020, and we established a phased-in return to work schedule commencing March&#160;15, 2021 for those employees working from home that was completed April 19, 2021. However, we continue to evaluate our ability to operate in the event of resurgences of COVID-19 and the advisability of continuing operations, based on federal, state and local guidance, evolving data concerning the pandemic and the best interests of our employees, customers and stockholders. For example, given the continued elevated number of COVID-19 cases throughout the U.S. as a result of the highly transmissible Delta and Omicron variants, we have instituted policies to protect our employees and customers such as a mandatory vaccination policy which required all U.S. employees to be fully vaccinated by November 1, 2021 or seek a qualified religious and/or medical exemption with weekly testing protocols. &#160;Accordingly, there can be no assurance that any of our facilities will remain open (in full or in part) or that our other operations will continue at full or limited capacity. If we again have to shut down production either due to a resurgence of the COVID-19 pandemic or due to an outbreak in one of our facilities, our project schedules and associated financing could be adversely affected. Further, we have experienced, and may continue to experience, increased costs and expenses, including as a result of (i)&#160;conducting daily &#8220;fitness-for-duty&#8221; assessments for employees, including symptom checks and providing personal protective equipment, (ii)&#160;the expansion of benefits to our employees, including the provision of additional time off for employees who have contracted COVID-19 or are required to be quarantined or who are unable to obtain childcare to return to work, and the reimbursement of expenses incurred while working from home, (iii)&#160;implementing increased health and safety protocols at all of our facilities, including increased cleaning/sanitization of workspaces, restricting visitor access, mandating social distancing guidelines and increasing the availability of sanitization products, and (iv)&#160;the increased cost of personal protective equipment. Although we believe the Company is currently considered an &#8220;essential&#8221; business in its operating markets, if any of the applicable exceptions or exemptions are curtailed or revoked in the future, or any of these exemptions or exceptions do not extend to any of our key suppliers, our business, operating results and financial condition could be adversely impacted. While we have attempted to continue business development activities during the pandemic, state and local shutdowns, shelter-in-place orders and travel restrictions have impeded our ability to meet with customers and solicit new business, and certain bids and solicitations in which we typically participate have been postponed. As a result, at this time, it is impossible to predict the overall impact of COVID-19 on our business, liquidity, capital resources, supply chain and financial results or its effect on clean energy demand, capital budgets of our customers, or demand for our products. Additionally, while we have continued to prioritize the health and safety of our team members and customers as we continue to operate during the pandemic, we face an increased risk of litigation related to our operating environments. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of any economic recession that has occurred or may occur in the future because of the pandemic, or because the pandemic worsens again. Additional public health crises could also emerge in the future, including other pandemics or epidemics. Any such public health crisis could pose further risks to us and could also have a material adverse effect on our business, results of operations and financial position<span style="font-size:12pt;">.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-size:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Risks Related to Sales of our Products</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">We derive significant revenue from contracts awarded through competitive bidding processes involving substantial costs and risks.

The competitive bidding process involves substantial costs and a number of risks, including the significant cost and managerial time to prepare bids and proposals for contracts that may not be awarded to us and our failure to accurately estimate the resources and costs that will be required to fulfill any contract we win. In addition, following a contract award, we may encounter significant expense, delay or contract modifications or award revocation as a result of our competitors protesting or challenging contracts awarded to us in competitive bidding.

Certain awards are cancelable or revocable at any time prior to contract execution. The time periods from receipt of an award to execution of a contract, or receipt of a contract to installation may vary widely and are determined by a number of factors, including the terms of the award, governmental policies or regulations that go into effect after the award, the terms of the customer contract and the customer&#8217;s site requirements. These same or similar conditions and contingencies may be required by financiers in order to draw on financing to complete a project. If these conditions or contingencies are not satisfied, or changes in laws affecting project awards occur, or awards are revoked or cancelled, project awards may not convert to contracts, and installations may be delayed or canceled. This could have an adverse impact on our revenue and cash flow and our ability to complete construction of a project.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">We have signed product sales contracts, EPCs, PPAs and long-term service agreements with customers subject to contractual, technology, operating, commodity (i.e. natural gas) and fuel pricing risks as well as market conditions that may affect our operating results.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">We apply the transfer of control over time revenue recognition method under Accounting Standards Codification Topic 606: Revenue from Contracts with Customers to certain service contracts which are subject to estimates. On a quarterly basis, we perform a review process to help ensure that total estimated contract costs include estimates of costs to complete that are based on the most recent available information. The amount of costs incurred on a cumulative to date basis as a function of estimated costs at completion is applied to contract consideration to determine the cumulative revenue that should be recognized to date.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">We have contracted under long-term service agreements with certain customers to provide service on our products over terms up to 20&#160;years. Under the provisions of these contracts, we provide services to maintain, monitor, and repair customer power plants to meet minimum operating levels. Pricing for service contracts is based upon estimates of future costs including future module exchanges. While we have conducted tests to determine the overall life of our products, we have not run certain of our products over their projected useful life or in all potential conditions prior to large scale commercialization. As a result, we cannot be sure that these products will last to their expected useful life or perform as anticipated in all conditions, which could result in warranty claims, performance penalties, maintenance and module replacement costs in excess of our estimates, losses on service contracts and/or a negative perception of our products. As a result of our products&#8217; maturity, we have incurred and may continue to incur charges for warranty claims, performance penalties, maintenance and module replacement costs in excess of our estimates and losses on service contracts. Each of these risks could be material under these contracts and, as a result, we may experience diminished returns or be required to write off all or a portion of our capitalized costs in these project assets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In certain instances, we have executed PPAs with the utility, end-user of the power or site host of the fuel cell power plant. We may then sell the PPA and power plant to a project investor or retain the project and collect revenue from the sale of power over the term of the PPA, recognizing electricity revenue as power is generated and sold. Our growing portfolio of project assets used to generate and sell power under PPAs and utility tariff programs exposes us to operational risks and uncertainties, including, among other things, lost revenues &#160;due to prolonged outages, replacement equipment costs, risks associated with facility start-up operations, failures in the availability or acquisition of fuel (including natural gas and renewable natural gas), the impact of severe adverse weather conditions, natural disasters, terrorist attacks, cybersecurity attacks, risks of property damage or injury from energized equipment, availability of adequate water resources and ability to intake and discharge water, use of new or unproven technology, fuel commodity price risk and fluctuating market prices, and lack of alternative available fuel sources.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Our ability to proceed with projects under development and complete construction of projects on schedule and within budget may be adversely affected by escalating costs for materials and fuel (including natural gas and renewable natural gas), supply chain and logistics challenges, tariffs, labor and regulatory compliance, inability to obtain necessary permits, interconnections or other approvals on acceptable terms or on schedule and by other factors. If any development project or construction is not completed, is delayed or is subject to cost overruns, we could become obligated to make delay or termination payments or become obligated for other damages under contracts, experience diminished returns or be required to write off all or a portion of our capitalized costs in the project. Each of these events could have an adverse effect on our business, financial condition, results of operations and prospects.<span style="font-size:12pt;"> </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="font-size:12pt;visibility:hidden;">&#8203;</span></p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">41</p></div></div></div>

We now produce stacks in the United States with a net rated power output of 350 kilowatts when new and a 7-year cell design life. We provide for a warranty of our products for a specific period of time against manufacturing or performance defects. We accrue for warranty costs based on historical warranty claim experience; however, actual future warranty expenses may be greater than we have assumed in our estimates. We are still gaining field operating experience with respect to our products, and despite experience gained from our growing installed base and testing performed by us, our customers and our suppliers, issues have been and may continue to be found in existing or new products including module decay rates which have in the exceeded and may continue to exceed design expectations. This has resulted and may continue to result in a delay in recognition or loss of revenues and may result in loss of market share or failure to achieve broad market acceptance. The occurrence of defects has also caused and may continue to cause us to incur significant warranty, support and repair costs in excess of our estimates, could divert the attention of our engineering personnel from our product development efforts, and could harm our relationships with our customers. Although we seek to limit our liability, a product liability claim brought against us, even if unsuccessful, would likely be time consuming, could be costly to defend, and may hurt our reputation in the marketplace. Our customers could also seek and obtain damages from us for their losses<span style="font-size:12pt;">.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="font-size:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">We currently face and will continue to face significant competition, including from products using other energy sources that may be lower priced or have preferred environmental characteristics.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">We compete on the basis of our products&#8217; reliability, efficiency, environmental considerations and cost. Technological advances in alternative energy products, improvements in the electric grid or other sources of power generation that use lower priced fuel or no fuel, or other fuel cell technologies may negatively affect the development or sale of some or all of our products or make our products less economically attractive, non- competitive or obsolete prior to or after commercialization. Significant decreases in the price of alternative technologies or grid delivered electricity, or significant increases in the price of our fuels could have a material adverse effect on our business because other generation sources could be more economically attractive to consumers than our products. Additionally, in certain markets, consumers and regulators have expressed a preference for zero-carbon generating resources over fueled resources, which could adversely affect sales of our products in such markets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Other companies, some of which have substantially greater resources than ours, are currently engaged in the development of products and technologies that are similar to, or may be competitive with, our products and technologies. Several companies in the U.S. are engaged in fuel cell development, although we are the only domestic company engaged in manufacturing and deployment of stationary carbonate fuel cells. Other emerging fuel cell technologies include small or portable PEM fuel cells, stationary phosphoric acid fuel cells, stationary Solid Oxide Fuel Cells, and small residential Solid Oxide Fuel Cells. Any of these technologies and any of our competitors has the potential to capture market share in our target markets. There are also other potential fuel cell competitors internationally that could capture market share.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Other than fuel cell developers, we must also compete with companies that manufacture combustion-based distributed power equipment, including various engines and turbines, and have well-established manufacturing, distribution, operating and cost features. Electrical efficiency of these products can be competitive with our SureSource power plants in certain applications. Significant competition may also come from gas turbine companies and large scale solar and wind technologies.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Our plans are dependent on market acceptance of our products.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Our plans are dependent upon market acceptance of, as well as enhancements to, our products. Fuel cell systems represent an emerging market, and we cannot be sure that potential customers will accept fuel cells as a replacement for traditional power sources or non-fuel based power sources, hydrogen generation sources or storage. As is typical in a rapidly evolving industry, demand and market acceptance for recently introduced products and services are subject to a high level of uncertainty and risk.

Our products utilize fuels such as natural gas and convert these fuels internally to hydrogen that is used by our products to generate electricity. Although our platforms do not combust fuels for the generation of electricity, the fuels we use are combustible and may be toxic. In addition, our SureSource products operate at high temperatures and use corrosive carbonate material, which could expose us to potential liability claims. Although we have incorporated a robust design and redundant safety features in our power plants, have established comprehensive safety, maintenance, and training programs, follow third-party certification protocols, codes and standards, and do not store natural gas or hydrogen at our power plants, we cannot guarantee that there will not be accidents. Any accidents involving our products or other hydrogen-using products could materially impede widespread market acceptance and demand for our products. In addition, we might be held responsible for damages beyond the scope of our insurance coverage.

We have experienced, and may continue &#160;to experience in the future, cybersecurity attacks that have resulted in unauthorized parties gaining access to our information technology systems and networks and, in one instance, gaining control of the information technology system at one of our power plants. However, to date, no cybersecurity attack has resulted in any material loss of data, interrupted our day-to-day operations or had a material impact on our financial condition, results of operations or liquidity. While we actively manage information technology security risks within our control, there can be no assurance that such actions will be sufficient to mitigate all potential risks to our systems, networks and data. In addition to the direct potential financial risk as we continue to build, own and operate generation assets, other potential consequences of a material cybersecurity attack include reputational damage, litigation with third parties, disruption to systems, unauthorized release of confidential or otherwise protected information, corruption of data, diminution in the value of our investment in research, development and engineering, and increased cybersecurity protection and remediation costs, which in turn could adversely affect our competitiveness, results of operations and financial condition. The amount of insurance coverage we maintain may be inadequate to cover claims or liabilities relating to a cybersecurity attack.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Additionally, the legal and regulatory environment surrounding information security and privacy in the U.S. and international jurisdictions is constantly evolving. Violation or non-compliance with any of these laws or regulations, contractual requirements relating to data security and privacy, or our own privacy and security policies, either intentionally or unintentionally, or through the acts of intermediaries could have a material adverse effect on our brand, reputation, business, financial condition and results of operations, as well as subject us to significant fines, litigation losses, third-party damages and other liabilities.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Tax, Accounting, Compliance and Regulatory Risks</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">We are required to maintain effective internal control over financial reporting. Our management previously identified a material weakness in our internal control over financial reporting which was remediated in the fourth quarter of fiscal year 2020. If other control deficiencies are identified in the future, we may not be able to report our financial results accurately, prevent fraud or file our periodic reports in a timely manner, which may adversely affect investor confidence in our Company and, as a result, the value of our common stock.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">We are required, pursuant to Section&#160;404 of the Sarbanes-Oxley Act (&#8220;Section&#160;404&#8221;), to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting. Complying with Section&#160;404 requires a rigorous compliance program as well as adequate time and resources. We may not be able to complete our internal control evaluation, testing and any required remediation in a timely fashion. Additionally, if we identify one or more material weaknesses in our internal control over financial reporting, we will not be able to assert that our internal controls are effective. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Our management previously identified a material weakness in our internal control over financial reporting which was remediated in the fourth quarter of fiscal year 2020.

Changes in those estimates and judgments could significantly affect our results of operations and financial condition.

Our business exposes us to the risk of harmful substances escaping into the environment, resulting in personal injury or loss of life, damage to or destruction of property, and natural resource damage. Depending on the nature of the claim, our current insurance policies may not adequately reimburse us for costs incurred in settling environmental damage claims, and in some instances, we may not be reimbursed at all. In addition, it is possible that industry-specific laws and regulations will be adopted covering matters such as transmission scheduling, distribution, emissions, and the characteristics and quality of our products, including installation and servicing. These regulations could limit the growth in the use of carbonate fuel cell products, decrease the acceptance of fuel cells as a commercial product and increase our costs and, therefore, the price of our products. We believe that our businesses are operating in compliance in all material respects with applicable environmental laws; however, these laws and regulations have changed frequently in the past and it is reasonable to expect additional and more stringent changes in the future. Accordingly, compliance with existing or future laws and regulations could have a material adverse effect on our business prospects, results of operations and financial condition. If we fail to comply with applicable environmental laws and regulations, governmental authorities may seek to impose fines and penalties on us or to revoke or deny the issuance or renewal of operating permits and private parties may seek damages from us. Under those circumstances, we might be required to curtail or cease operations, conduct site remediation or other corrective action, or pay substantial damage claims.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Given that some of our product configurations run on fossil fuels, we may be negatively impacted by CO<sub style="font-size:7.5pt;vertical-align:sub;">2</sub>-related changes in applicable laws, regulations, ordinances, rules&#160;or the requirements of the incentive programs on which we and our customers currently rely. Changes in any of the laws, regulations, ordinances or rules&#160;that apply to our installations and new technology could make it illegal or more costly for us or our customers to install and operate our products at particular sites. Additionally, our customers and potential customers&#8217; energy procurement policies may prohibit or limit their willingness to procure our products. Our business prospects may be negatively impacted if we are prevented from completing new installations or our installations become more costly as a result of laws, regulations, ordinances, or rules&#160;applicable to our products, or by our customers&#8217; and potential customers&#8217; energy procurement policies.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In addition, certain of our products benefit from federal, state and local governmental incentives, mandates or other programs promoting clean energy generation.

These agencies review a contractor&#8217;s performance under its contracts, cost structure, and compliance with applicable laws, regulations, and standards. If the agencies determine through these audits or reviews that we improperly allocated costs to specific contracts, they will not reimburse us for these costs.

We are subject to export control laws and regulations, including the International Traffic in Arms Regulation, the Export Administration Regulation, and the Specially Designated Nationals and Blocked Persons List, which generally prohibit U.S. companies and their intermediaries from exporting certain products, importing materials or supplies, or otherwise doing business with restricted countries, businesses or individuals, and require companies to maintain certain policies and procedures to ensure compliance. We are also subject to the Foreign Corrupt Practices Act, which prohibits improper payments to foreign governments and their officials by U.S. and other business entities. Under these laws and regulations, U.S. companies may be held liable for their actions and actions taken by their strategic or local partners or representatives. If we, or our intermediaries, fail to comply with the requirements of these laws and regulations, or similar laws of other countries, governmental authorities in the United States or elsewhere, as applicable, could seek to impose civil and/or criminal penalties, which could damage our reputation and have a material adverse effect on our business, financial condition and results of operations.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="font-style:italic;font-weight:bold;visibility:hidden;">&#8203;</span></p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">46</p></div></div></div>

Pursuant to the PPP Note, we received total proceeds of approximately $6.5 million on April&#160;24, 2020 (the &#8220;PPP Loan&#8221;). In accordance with the requirements of the CARES Act, as amended by the Paycheck Protection Program Flexibility Act of 2020 (the &#8220;PPP Flexibility Act&#8221;), the PPP Loan may have been fully forgiven if (i)&#160;proceeds were used to pay eligible payroll costs, rent, mortgage interest and utilities and (ii)&#160;full-time employee headcount and salaries were either maintained during the 24-week period following disbursement of the PPP Loan or restored by December&#160;31, 2020. If not so maintained or restored, forgiveness of the PPP Loan would have been reduced in accordance with regulations issued by the SBA. In order to obtain the consent of the Orion Agent and the lenders under the Orion Credit Agreement (each as defined elsewhere in this document) to enter into the PPP Note, the Orion Agent and such lenders required us to apply for forgiveness within 30&#160;days after the last day of the loan forgiveness period as designated under regulations in effect as of June&#160;6, 2020. We used 100% of the proceeds of the PPP Loan to pay eligible payroll costs, and on October&#160;29, 2020, we applied for forgiveness of the PPP Loan. However, with the repayment in full of all amounts owed to the Orion Agent and related lenders in December 2020, we were no longer required to pursue forgiveness of the PPP Loan. Additionally, since the time of the application for forgiveness, our financial circumstances changed substantially, such that we were no longer in need of forgiveness of the PPP Loan. While we believe we met all of the requirements of the CARES Act, as amended by the PPP Flexibility Act, for forgiveness, on February&#160;11, 2021, we withdrew our application for forgiveness and repaid all amounts outstanding under the PPP Note, together with all accrued interest.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In addition, based on guidance from the United States Department of the Treasury, since the total PPP Loan proceeds exceeded $2.0 million, our forgiveness application is subject to audit by the SBA, including with respect to our certification that the economic uncertainty at the time of our application made our request for a PPP Loan necessary to support our ongoing operations. If we are found to have been ineligible to receive the PPP Loan under the PPP Note, or in violation of any of the laws or regulations that may apply to us in connection with the PPP Note, including the False Claims Act, we may be subject to enforcement actions, fines and penalties, including significant civil, criminal and administrative penalties. In addition, our receipt of the PPP Loan, our submission of a forgiveness application, and our withdrawal of our forgiveness application may result in adverse publicity and damage to our reputation, governmental investigations, inquiries, reviews and audits, such as the SEC inquiry described below, which could consume significant financial and management resources. Any of these events could harm our business, results of operations and financial condition.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On or about May&#160;11, 2020, the Division of Enforcement of the SEC sent us an inquiry requesting that we voluntarily provide information to the SEC pertaining to our application and resulting PPP Loan and how the need for the PPP Loan compares with our filings, disclosures and financial condition.

For such sales, we often require substantial cash down payments in advance of delivery. For our generation business, we must invest substantial amounts in application design, manufacture, installation, commissioning and operation, which amounts are returned through energy sales over long periods of time. Our growth strategy assumes that financing will be available for us to finance working capital or for our customers to provide down payments and to pay for our products.

The loss of the services of any such personnel could materially adversely affect our business. Our ability to achieve our commercialization plans and to increase production at our manufacturing facility in the future will also depend on our ability to attract and retain additional qualified personnel, and we cannot assure you that we will be able to do so. Recruiting personnel for the fuel cell industry is competitive. Our inability to attract and retain additional qualified personnel, or the departure of key employees, could materially and adversely affect our development, commercialization and manufacturing plans and, therefore, our business prospects, results of operations and financial condition. In addition, our inability to attract and retain sufficient personnel to quickly increase production at our manufacturing facility when and if needed to meet increased demand may adversely impact our ability to respond rapidly to any new product, growth or revenue opportunities. Our inability to attract and retain sufficient qualified personnel to staff our government or third party funded research contracts may result in our inability to complete such contracts or terminations of such contracts, which may adversely impact financial conditions and results of operations.</p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">52</p></div></div></div>

We have limited experience developing and manufacturing our products to comply with the commercial and legal requirements of international markets. In addition, we are subject to tariff regulations and requirements for export licenses, particularly with respect to the export of some of our technologies. We face numerous challenges in our international expansion, including unexpected changes in regulatory requirements and other geopolitical risks, fluctuations in currency exchange rates, longer accounts receivable requirements and collections, greater bonding and security requirements, difficulties in managing international operations, potentially adverse tax consequences, restrictions on repatriation of earnings and the burdens of complying with a wide variety of international laws. Any of these factors could adversely affect our results of operations and financial condition.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">We source raw materials and parts for our products on a global basis, which subjects us to a number of potential risks, including the impact of export duties and quotas, trade protection measures imposed by the U.S. and other countries including tariffs, potential for labor unrest, changing global and regional economic conditions and current and changing regulatory environments. Changes to these factors may have an adverse effect on our ability to source raw materials and parts in line with our current cost structure.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Although our reporting currency is the U.S. dollar, we conduct our business and incur costs in the local currency of most countries in which we operate. As a result, we are subject to currency translation and transaction risk. Changes in exchange rates between foreign currencies and the U.S. dollar could affect our net sales and cost of sales and could result in exchange gains or losses. We cannot accurately predict the impact of future exchange rate fluctuations on our results of operations.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">We could also expand our business into new and emerging markets, many of which have an uncertain regulatory environment relating to currency policy. Conducting business in such markets could cause our exposure to changes in exchange rates to increase, due to the relatively high volatility associated with emerging market currencies and potentially longer payment terms for our proceeds. Our ability to hedge foreign currency exposure is dependent on our credit profile with financial institutions that are willing and able to do business with us. Deterioration in our credit position or a significant tightening of the credit market conditions could limit our ability to hedge our foreign currency exposure and, therefore, result in exchange gains or losses.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><a

Franklin Park&#8217;s tax equity commitment totals $12.4 million.&#160;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">This transaction was structured as a &#8220;partnership flip&#8221;, which is a structure commonly used by tax equity investors in the financing of renewable energy projects. Under this partnership flip structure, a partnership, in this case YTBFC Holdco, LLC (the &#8220;Yaphank Partnership&#8221;), was organized to acquire from FuelCell Energy Finance II, LLC, our wholly-owned subsidiary, all outstanding equity interests in Yaphank Fuel Cell Park, LLC (the &#8220;Yaphank Project Company&#8221;) which in turn owns the LIPA Yaphank Project and is the party to the power purchase agreement and all project agreements. At the closing of the transaction, the Yaphank Partnership is owned by Franklin Park, holding Class A Units, and Fuel Cell Energy Finance Holdco, LLC, a subsidiary of FuelCell Energy Finance, LLC, holding Class B Units. The acquisition of the Yaphank Project Company by the Yaphank Partnership was funded in part by an initial draw from Franklin Park and funds contributed downstream to the Yaphank Partnership by us. The initial funding occurred on December 13, 2021, upon the satisfaction of certain conditions precedent (including the receipt of an appraisal and confirmation that the LIPA Yaphank Project would be eligible for the investment tax credit (&#8220;ITC&#8221;) under Section 48 of the Internal Revenue Code of 1986, as amended). &#160;In connection with the initial closing, we were able to draw down approximately $3.2 million, of which approximately $0.4 million was used to pay closing costs, including title insurance expenses and legal and consulting fees. We are eligible to draw the remaining amount of the commitment, approximately $9.2 million, once the LIPA Yaphank Project achieves commercial operation. &#160;When such funds are drawn down, the funds will be distributed upstream to us, as a reimbursement of prior construction costs incurred by us.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Under a partnership flip structure, tax equity investors agree to receive a minimum target rate of return, typically on an after-tax basis. Prior to receiving a contractual rate of return or a date specified in the contractual arrangements, Franklin Park will receive substantially all of the non-cash value attributable to the LIPA Yaphank Project, which includes accelerated depreciation and Section 48(a) investment tax credits; however, we will receive a majority of the cash distributions (based on the operating income of the LIPA Yaphank Project), which are paid quarterly. After Franklin Park receives its contractual rate of return, we will receive approximately 95% of the cash and tax allocations. We (through a separate wholly owned entity) may enter into a back leverage debt financing transaction and use the cash distributions from the Yaphank Partnership to service the debt. &#160;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Under this partnership flip structure, after the fifth anniversary following commercial operations, we have an option to acquire all of the equity interests that Franklin Park holds in the Yaphank Partnership starting after Franklin Park receives its contractual rate of return (the anticipated &#8220;flip&#8221; date) after the LIPA Yaphank Project is operational.

The primary reason for the lack of product revenues in recent years is that, in the United States, the Company chose to invest in retaining assets on its balance sheet and building its generation operating portfolio rather than selling these projects to customers or project investors, &#160;with the goal of benefitting from the long-term cash flows under the PPAs relating to the retained projects. In addition, <span style="background:#ffffff;">internationally, South Korea and Europe have historically been product sale markets for the Company; however, we have not recognized meaningful product revenues in these geographies since 2018. Our activities in South Korea have been impacted by our prior dispute with POSCO Energy and, until fiscal year 2021, we moderated our investment in business development in Europe due to limited resources</span>.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:6pt 0pt 0pt 0pt;">Cost of product revenues decreased $1.9 million for the&#160;year ended October&#160;31, 2021 to $8.0 million, compared to $9.9 million for the&#160;year ended October&#160;31, 2020. Both periods were impacted by the under-absorption of fixed overhead costs due to low production volumes. Manufacturing variances, primarily related to low production volumes and unabsorbed overhead costs, totaled approximately $6.9 million for the year ended October 31, 2021 compared to approximately $8.7 million for the year ended October 31, 2020. The Company incurred approximately $2.1 million of manufacturing variances during the year ended October 31, 2020 due to the manufacturing facility shutdown, which negatively impacted overall gross margin. The decrease in manufacturing variances is primarily the result of increased production volumes during the year ended October 31, 2021.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:6pt 0pt 0pt 0pt;">For the&#160;year ended October&#160;31, 2021, we operated at an annualized production rate of approximately 32.4 MW, which is an increase from the annualized production rate of 17.0 MW for the year ended October 31, 2020. &#160;The fiscal year 2020 production rate was primarily a result of the manufacturing facility shutdown that was implemented in response to the COVID-19 pandemic.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:6pt 0pt 0pt 0pt;">As of

Because we recognize revenue on service contracts over time using a cost input method in accordance with Accounting Standards Codification Topic 606 (&#8220;ASC 606&#8221;), we evaluate the cost estimates associated with each service contract periodically and adjust revenue accordingly. In fiscal year 2021, we reviewed our cost estimates relating to our service contracts and identified higher estimated costs than those that were previously identified. These higher estimated costs are due to our expectation that supply chain costs will remain high relative to prior years and that our production volumes will remain low, resulting in an increase in expected carrying costs. Because our estimated costs relating to the service contracts increased, we applied a reduction in revenue of $1.0 million in the year ended October 31, 2021 in accordance with ASC 606.</span><span style="font-family:'Times New Roman','Times','serif';font-size:12pt;font-style:normal;font-weight:normal;"> </span><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"> </span></td></tr></table><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">63</p></div></div></div>

We record loss accruals for service agreements when the estimated cost of future module exchanges and maintenance and monitoring activities exceeds the remaining unrecognized consideration. Estimates for future costs on service agreements are determined by a number of factors including the estimated remaining life of the module(s), used replacement modules available, and future operating plans for the power platform. The net increase of approximately $1.6 million to the loss accrual in fiscal year 2021 was a result of the higher future cost estimates related to future module exchanges, as further described above, as well as earlier timing of exchanges of certain modules during the fiscal year compared to our prior estimates as a result of lower than expected performance. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">We work to continuously improve and mature our products and implement lessons learned into our product designs and manufacturing process subsequent to introduction. In 2021, we examined data related to module field performance, identified improvement opportunities and invested in improvement initiatives with respect to our core molten carbonate technology. We identified improvement opportunities ranging from improved thermal management by reducing internal temperature to improving the performance of our electrical balance of plant and began to implement design changes to our commercial platforms which are expected to improve overall product performance. As it relates to our fuel cell modules, these improvements centered around delivering more uniform temperature distribution within the stack modules with the intent of improving output over the life of the modules to achieve the product&#8217;s expected design life.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-size:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Cost of service and license revenues for both years include planned maintenance activities, module exchanges and continued investment in the service fleet in order to improve performance.

The decrease is primarily a result of (i) the lack of revenue comparable to the revenue of $4.0 million associated with the EMRE Joint Development Agreement and $0.7 million associated with the POSCO Energy License Agreements, in each case recognized during the year ended October 31, 2020, and (ii) higher future cost estimates related to future module exchanges which resulted in a negative margin impact of approximately $2.6 million. These impacts to gross margin were partially offset by the favorable mix associated with module exchange activities as module exchanges in fiscal year 2021 were for higher margin projects, which increased margins by approximately $1.8 million. The overall gross margin&#160;was (25.0%) for the year ended October 31, 2021, compared to a gross margin of 2.3% for the year ended October 31, 2020.

Cost of generation revenues included depreciation and amortization of approximately $15.0 million and $13.9 million for the years ended October 31, 2021 and 2020, respectively, and the increase reflects accelerated depreciation expense recorded for module exchanges during the year ended October 31, 2021.<span style="font-size:12pt;"> </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-size:9pt;margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Fiscal years 2021 and 2020 both included an impairment charge for the Triangle Street Project.

We use the Triangle Street Project as a development platform for our advanced applications.

It was determined in the fourth quarter of fiscal year 2021 that a potential source of RNG at favorable pricing was no longer sufficiently probable and that market pricing for RNG has significantly increased, resulting in the determination that the carrying value of the project asset is no longer recoverable. &#160;While the Company is pursuing alternative sources of RNG, a $2.8 million impairment charge was recorded, which represents the carrying value of the project asset less the carrying value of inventory components that could be redeployed for alternative use<span style="font-size:12pt;">. </span>The Company may continue to incur such charges in future periods.<span style="font-size:12pt;"> </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-size:9pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Refer to Note&#160;7. &#8220;Project Assets&#8221; to the Consolidated Financial Statements for more information on the impairment charges for the fiscal year ended October 31, 2021. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-size:9pt;margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">The overall gross loss from generation revenues was $12.0 million for the&#160;year ended October&#160;31, 2021, which represents an increase of $4.1 million from a gross loss of $7.9 million for the&#160;year ended October&#160;31, 2020.

ended October 31, 2020. Compared to the year ended October 31, 2020, Advanced Technologies contract revenues recognized under the EMRE Joint Development Agreement were approximately $1.3 million higher during the year ended October 31, 2021, reflecting continued performance under the EMRE Joint Development Agreement during the year ended October 31, 2021. However, the increased revenues under the EMRE Joint Development Agreement were offset by the $1.4 million less revenue recognized under government contracts during the year ended October 31, 2021 than during the year ended October 31, 2020. Cost of Advanced Technologies contract revenues increased $0.2 million to $16.5&#160;million for the year ended October 31, 2021, compared to $16.3 million for the year ended October 31, 2020. Advanced Technologies contracts for the year ended October 31, 2021 generated a gross margin of $9.3 million compared to a gross margin of $9.5 million for the year ended October 31, 2020. The decrease in Advanced Technologies contract gross margin is related to the mix of government contracts, which resulted in a higher cost share incurred by the Company on such contracts in the year ended October 31, 2021 compared to the year ended October 31, 2020.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">As of October&#160;31, 2021, Advanced Technologies contract backlog totaled $40.8 million compared to $49.2 million at October&#160;31, 2020.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Administrative and selling expenses</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Administrative and selling expenses were $37.9 million and $26.6&#160;million for the years ended October 31, 2021 and 2020, respectively. The year ended October 31, 2021 included higher legal expenses for tax equity financings (refer to Note&#160;4. &#8220;Tax Equity Financing&#8221; to the Consolidated Financial Statements for more information regarding the tax equity financings), additional expense for shared-based compensation of $2.2 million primarily due to the grants made in August&#160;2020 and November&#160;2020 under our Long-Term Incentive Plans (refer to Note&#160;18. &#8220;Benefit Plans&#8221; to the Consolidated Financial Statements for more information on the August and November&#160;2020 grants), increased compensation expense and proxy mailing expenses associated with the Company&#8217;s annual stockholder meeting. The year ended October 31, 2020 also included a legal settlement of $2.2 million which was recorded as an offset to administrative and selling expenses.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Research and development expenses</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Research and development expenses increased to $11.3 million for the year ended October 31, 2021 compared to $4.8 million for the year ended October 31, 2020. The increase relates to an increase in spending on the Company&#8217;s hydrogen commercialization initiatives compared to the year ended October 31, 2020. The year ended October 31, 2020 was impacted by restructuring initiatives implemented in 2019 and the reallocation of resources from Company-funded research and development projects to funded Advanced Technologies projects. During the year ended October 31, 2021, the Company successfully commenced operation and testing of a prototype solid oxide electrolysis hydrogen platform in Danbury, Connecticut.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Loss from operations</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Loss from operations for the year ended October 31, 2021 was $64.9 million compared to $39.2 million for the year ended October 31, 2020. This increase was due to an increase in gross loss of $7.9 million and a $17.8 million increase in operating expenses for the year ended October 31, 2021. </p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">66</p></div></div></div>

These impacts were partially offset by lower manufacturing variances primarily resulting from increased production volumes<span style="font-size:12pt;">.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Operating expenses were higher in the period as administrative and selling expenses and research and development expenses both increased for the year ended October 31, 2021. Administrative and selling expenses included legal expenses for tax equity financings, additional share-based compensation expense under our Long Term Incentive Plans approved in August 2020 and November 2021, an increase in compensation expense, and proxy mailing expenses associated with the Company&#8217;s annual stockholder meeting. In addition, administrative and selling expenses for the year ended October 31, 2020 included a $2.2 million legal settlement that offset administrative and selling expenses and there was no comparable gain for the year ended October 31, 2021.

Interest expense for both periods presented includes interest related to financing obligations for sale-leaseback transactions and on the outstanding loans associated with the Bridgeport Fuel Cell Project. Interest expense for both periods also includes interest for the amortization of the redeemable preferred stock of subsidiary fair value discount. Amounts owed pursuant to the terms of the redeemable preferred stock issued by FCE Ltd. (which is referred to elsewhere herein as the Series 1 Preferred Shares) were paid, in full, in December&#160;2020. The decrease in interest expense for the year ended October 31, 2021 is primarily due to the repayment of the $80.0 million principal balance outstanding under the Orion Credit Agreement (as defined below), which was fully repaid in December&#160;2020.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Change in fair value of common stock warrant liability</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">The $16.0 million expense for the year ended October 31, 2021 represents an adjustment to the estimated fair value of the unexercised Orion Warrants outstanding during the year ended October 31, 2021, which were exercised, in full, during the year ended October 31, 2021. The $37.1 million expense for the&#160;year ended October&#160;31, 2020 represents an adjustment to the estimated fair value of the Orion Warrants outstanding as of October 31, 2020. The expense is primarily a result of increases in the price of our common stock during the&#160;year ended October&#160;31, 2020, which were used as an input to remeasure the Orion Warrants to fair value on a quarterly basis using a Black-Scholes model at October 31, 2020 for unexercised warrants as of October 31, 2020 and the dates of exercise compared to the stock price used in the Black-Scholes model upon the issuance of the Orion Warrants<span style="font-size:12pt;">.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:9pt 0pt 0pt 0pt;"><b style="font-weight:bold;">Loss (gain) on extinguishment of debt and financing obligation</b></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:9pt 0pt 0pt 0pt;">The loss on extinguishment of debt for the year ended October 31, 2021 represents costs associated with the repayment of the $80.0 million principal balance outstanding under the Orion Credit Agreement.

The increase in the net loss attributable to common stockholders for the year ended October 31, 2021 is primarily due to incurring (i)&#160; a gross loss for fiscal year 2021 compared to a gross profit for fiscal&#160;year 2020, (ii)&#160;higher operating expenses for fiscal year 2021, (iii)&#160;an $11.2 million loss recorded on the extinguishment of the Orion Facility, and (iv)&#160;a $0.9 million charge for the extinguishment of the Series 1 Preferred Share obligation. These amounts were offset by lower interest expense due to repayment of the Orion Facility and a lower charge for the change in fair value of common stock warrant liability. The net loss attributable to common stockholders for the year ended October 31, 2020 reflected a $1.8 million gain on the extinguishment of a financing obligation. &#160;There was no comparable gain recorded in the year ended October 31, 2021. The lower loss per common share for the year ended October 31, 2021 as compared to the year ended October 31, 2020 is due to the higher weighted average shares outstanding as of October 31, 2021 as a result of share issuances since October 31, 2020.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;text-align:center;margin:0pt 0pt 12pt 0pt;">LIQUIDITY AND CAPITAL RESOURCES</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Overview, Cash Position, Sources and Uses</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:9pt 0pt 0pt 0pt;">Our principal sources of cash have been sales of our common stock through public equity offerings, proceeds from third party debt, project financing and tax monetization transactions, proceeds from the sale of our projects as well as research and development and service and license agreements with third parties.

This strategy requires liquidity and the Company expects to continue to have increasing liquidity requirements as project sizes increase and more projects are added to backlog. We may commence building project assets upon the award of a project or execution of a multi-year PPA with an end-user that has a strong credit profile. Project development and construction cycles, which span the time between securing a PPA and commercial operation of the platform, vary substantially and can take&#160;years. As a result of these project cycles and strategic decisions to finance the construction of certain projects, we may need to make significant up-front investments of resources in advance of the receipt of any cash from the sale or long-term financing of such projects. To make these up-front investments, we may use our working capital, seek to raise funds through the sale of equity or debt securities, or seek other financing arrangements. Delays in construction progress and completing current projects in process within budget, or in completing financing or the sale of our projects may impact our liquidity in a material way.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Our generation operating portfolio (34.0 MW as of October 31, 2021) contributes higher long-term cash flows to the Company than if these projects had been sold. These projects currently generate approximately $26.0 million per&#160;year in annual revenue, but this amount may fluctuate from&#160;year to&#160;year depending on platform output, operational performance and management and site conditions. The Company plans to continue to grow this portfolio while also selling projects to investors. As of October 31, 2021, the Company had projects representing an additional 41.3 MW in various stages of development and construction, which projects are expected to generate operating cash flows in future periods, if completed. Retaining long-term cash flow positive projects, combined with our service fleet, is expected to result in reduced reliance on new project sales to achieve cash flow positive operations, however, operations and performance issues could impact results. We have worked with and are continuing to work with lenders and financial institutions to secure construction financing, long-term debt, tax equity and sale-leasebacks for our project asset portfolio, but there can be no assurance that such financing can be attained, or that, if attained, it will be retained and sufficient.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">As of October 31, 2021, net debt outstanding related to project assets was $74.2 million. Future required payments totaled $43.2 million as of October 31, 2021. The outstanding financing obligations under our sale-leaseback transactions, which totaled $56.5 million as of October 31, 2021, include $34.8 million in excess of future required payments, not including amounts for the potential repurchase price of the project assets which is based on fair value. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Our generation operating portfolio provides us with the full benefit of future cash flows, net of any debt service requirements.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">70</p></div></div></div>

On September 14, 2021, the Company disclosed that the process of commissioning the Groton Project was temporarily suspended due to a needed repair. The Company also disclosed that if commercial operations were delayed beyond October 18, 2021, an extension would be required from the Navy. Extensions were received from the Navy extending the date by which commercial operations are to be achieved to February 15, 2022.&#160;In November 2021, the Company completed all necessary repairs and resumed commissioning of the project.

(&#8220;East West Bank&#8221;) for this project. East West Bank&#8217;s tax equity commitment totals $15 million. In connection with the initial closing, the Company was able to draw down $3.0 million. The Company is eligible to draw the remaining amount of the commitment, approximately $12 million, once the Groton Project achieves commercial operation. Under the terms of the Company&#8217;s agreement with East West Bank, the project had a required commercial operation deadline of October 18, 2021. On October 18, 2021, East West Bank granted an extension of the commercial operation deadline to December 31, 2021. On December 27, 2021, in exchange for a fee of $0.2 million, East West Bank granted a further extension of the commercial operation deadline to February 15, 2022. If commercial operations are delayed beyond February 15, 2022, extensions would be required from East West Bank and the Navy and those parties will determine whether such extensions will be granted in their sole discretion.

Estimates are used in accounting for, among other things, revenue recognition, contract loss accruals, excess, slow-moving and obsolete inventories, product warranty accruals, loss accruals on service agreements, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of goodwill and in-process research and development intangible assets, impairment of long-lived assets (including project assets), lease liabilities and right-of-use (&#8220;ROU&#8221;) assets, and contingencies. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Our critical accounting policies are those that are both most important to our financial condition and results of operations and require the most difficult, subjective or complex judgments on the part of management in their application, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

If events or changes in circumstances indicate that the carrying amount of the asset group may not be recoverable, we compare the carrying amount of an asset group to future undiscounted net cash flows, excluding interest costs, expected to be generated by the asset group and their ultimate disposition. If the sum of the undiscounted cash flows is less than the carrying value, the impairment to be recognized is measured by the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. During the&#160;years ended October&#160;31, 2021 and 2020, the Company recorded certain project asset impairment charges.

Under Topic 606: <i style="font-style:italic;">Revenue from Contracts with Customers, </i>the amount of revenue recognized for any goods or services reflects the consideration that the Company expects to be entitled to receive in exchange for those goods and services. To achieve this core principle, the Company applies the following five-step approach: (1)&#160;identify the contract with the customer; (2)&#160;identify the performance obligations in the contract; (3)&#160;determine the transaction price; (4)&#160;allocate the transaction price to performance obligations in the contract; and (5)&#160;recognize revenue when or as a performance obligation is satisfied.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">A contract is accounted for when there has been approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Performance obligations under a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct and are distinct in the context of the contract. In certain instances, the Company has concluded distinct goods or services should be accounted for as a single performance obligation that is a series of distinct goods or services that have the same pattern of transfer to the customer. To the extent a contract includes multiple promised goods or services, the Company must apply judgment to determine whether the customer can benefit from the goods or services either on their own or together with other resources that are readily available to the customer (the goods or services are distinct) and if the promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract (the goods or services are distinct in the context of the contract). If these criteria are not met, the promised services are accounted for as a single performance obligation. The transaction price is determined based on the consideration that the Company will be entitled to in exchange for transferring goods or services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price, generally utilizing the expected value method. Determining the transaction price requires judgment. If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price basis. Standalone selling price is determined by the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price by taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. Performance obligations are satisfied either over time or at a point in time as discussed in further detail below. In addition, the Company&#8217;s contracts with customers generally do not include significant financing components or non-cash consideration. The Company has elected practical expedients in the accounting guidance that allow for revenue to be recorded in the amount that the Company has a right to invoice, if that amount corresponds directly with the value to the customer of the Company&#8217;s performance to date, and that allow the Company not to disclose related unsatisfied performance obligations. The Company records any amounts that are billed to customers in excess of revenue recognized as deferred revenue and revenue recognized in excess of amounts billed to customers as unbilled receivables.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Revenue streams are classified as follows:</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">Product.</b> Includes the sale of completed project assets, sale and installation of fuel cell power platforms including site engineering and construction services, and the sale of modules, BOP components and spare parts to customers.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">Service.</b> Includes performance under long-term service agreements for power platforms owned by third parties.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">License and royalty.</b> Includes license fees and royalty income from the licensure of intellectual property.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">Generation.</b> Includes the sale of electricity under PPAs and utility tariffs from project assets retained by the Company.

The Company has determined that it is the primary beneficiary in the Groton Partnership for accounting purposes. The Company has considered the provisions within the financing-related agreements (including the limited liability company agreement for the Groton Partnership) which grant the Company power to manage and make decisions affecting the operations of the Groton Partnership. The Company considers the rights granted to East West Bank under the agreements to be more protective in nature than participatory. Therefore, the Company has determined under the power and benefits criterion of Accounting Standards Codification 810, <i style="font-style:italic;">Consolidations </i>that it is the primary beneficiary of the Groton Partnership. As the primary beneficiary, the Company consolidates in its consolidated financial statements the financial position, results of operations and cash flows of the Groton Partnership, and all intercompany balances and transactions between the Company and the Groton Partnership are eliminated in the consolidated financial statements. The Company recognized East West Bank&#8217;s share of the net assets of the Groton Partnership, which is $3.0 million as of October 31, 2021, as a noncontrolling interest in mezzanine equity on its Consolidated Balance Sheet and will continue to do so until the conditional withdrawal period lapses at the commencement of operations. Upon commencement of operations of the related project asset, the Company expects to allocate profits and losses to the noncontrolling interest under the hypothetical liquidation at book value (&quot;HLBV&quot;) method. HLBV is a balance sheet-oriented approach for allocating net income or loss to the noncontrolling interest when there is a complex structure, such as the partnership flip structure.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">See Note. 4 &#8220;Tax Equity Financing&#8221; for additional information regarding the tax equity financing transaction with East West Bank.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Sale-Leaseback Accounting</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Company, through certain wholly-owned subsidiaries, has entered into sale-leaseback transactions for commissioned project assets where we have entered into a PPA with a customer who is both the site host and end user of the power. Due to the Company not meeting criteria to account for the transfer of the project assets as a sale, sale accounting is precluded. Accordingly, the Company uses the financing method to account for these transactions.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Under the financing method of accounting for a sale-leaseback, the Company does not derecognize the project assets and does not recognize as revenue any of the sale proceeds received from the lessor that contractually constitutes payment to acquire the assets subject to these arrangements. Instead, the sale proceeds received are accounted for as financing obligations and leaseback payments made by the Company are allocated between interest expense and a reduction to the financing obligation. Interest on the financing obligation is calculated using the Company&#8217;s incremental borrowing rate at the inception of the arrangement on the outstanding financing obligation. While we receive financing for the related project asset, we have not recognized revenue on the sale-leaseback transactions. Instead, revenue is recognized with respect to the related PPAs in accordance with the Company&#8217;s policies for recognizing generation revenues.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Inventories</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Inventories consist principally of raw materials and work-in-process. &#160;Cost is determined using the first-in, first-out cost method. Included in our inventory balance are used modules that are brought back into inventory upon installation of new modules. When a new module is installed, a determination is made as to whether the module has remaining useful life or should be scrapped and materials recycled. Modules that are deemed to have remaining useful life are put into inventory at an estimated value based on the expected remaining life of the module and its projected output. Inventories are reviewed to determine if valuation allowances are required for excess, obsolete, and slow-moving inventory. This review includes analyzing inventory levels of individual parts considering the current design of our products and production requirements as well as the expected inventory requirements for maintenance on installed power platforms and inventory will be recorded at a new cost basis if a valuation allowance is required.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Service Expense Recognition</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">We have entered into service agreements with certain customers to provide monitoring, maintenance and repair services for fuel cell power platforms.

Estimates for future costs on service agreements are determined by a number of factors including the estimated remaining life of the module, used replacement modules available, and future operating plans for the power platform. Our estimates are performed on a contract by contract basis and include cost assumptions based on what we anticipate the service requirements will be to fulfill obligations for each contract.

We make purchases from certain vendors in currencies other than U.S. dollars. Although we have not experienced significant foreign exchange rate losses to date, we may in the future, especially to the extent that we do not currently engage in currency hedging activities. The economic impact of currency exchange rate movements on our operating results is complex because such changes are often linked to variability in real growth, inflation, interest rates, governmental actions and other factors.

The net interest rate across the BFC Credit Agreement and the swap transaction results in a fixed rate of 5.09%. The interest rate swap is adjusted to fair value on a quarterly basis. The estimated fair value is based on Level 2 inputs including primarily the forward LIBOR curve available to swap dealers. The valuation methodology involves comparison of (i)&#160;the sum of the present value of all&#160;monthly variable rate payments based on a reset rate using the forward LIBOR curve and (ii)&#160;the sum of the present value of all&#160;monthly fixed rate payments on the notional amount, which is equivalent to the outstanding principal amount of the loan. The fair value adjustment for the&#160;years ended October&#160;31, 2021 and October&#160;31, 2020 resulted in a $0.5 million gain and a $0.3 million charge, respectively.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Project Fuel Price Exposure Risk</p><a id="_Hlk90632421"></a><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Certain of our PPAs for project assets in our generation operating portfolio and project assets under construction expose us to fluctuating fuel price risks as well as the risk of being unable to procure the required amounts of fuel and the lack of alternative available fuel sources. We seek to mitigate our fuel risk using strategies including: (i) fuel cost reimbursement mechanisms in our PPAs to allow for pass through of fuel costs (full or partial) where possible which we have done with our 14.9 MW operating project in Bridgeport, CT and our 7.4 MW project under construction in Hartford, CT; (ii) procuring fuel under fixed price physical contracts with investment grade counterparties which we have done for twenty years for our Tulare BioMAT project and the initial seven years of the twenty year PPA for our LIPA Yaphank, NY project; and (iii) entering into future financial hedges with investment grade counterparties to offset potential negative market fluctuations.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">We currently have three projects in development with fuel sourcing risk, which are the Toyota Project, which requires procurement of renewable natural gas (&#8220;RNG&#8221;) which is not a commodity, and our Derby, CT 14.0 MW and 2.8 MW projects, which require natural gas which is a commodity.

Under Topic 606: <i style="font-style:italic;">Revenue from Contracts with Customers, </i>the amount of revenue recognized for any goods or services reflects the consideration that the Company expects to be entitled to receive in exchange for those goods and services. To achieve this core principle, the Company applies the following five-step approach: (1)&#160;identify the contract with the customer; (2)&#160;identify the performance obligations in the contract; (3)&#160;determine the transaction price; (4)&#160;allocate the transaction price to performance obligations in the contract; and (5)&#160;recognize revenue when or as a performance obligation is satisfied.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">A contract is accounted for when there has been approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Performance obligations under a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct and are distinct in the context of the contract. In certain instances, the Company has concluded distinct goods or services should be accounted for as a single performance obligation that is a series of distinct goods or services that have the same pattern of transfer to the customer. To the extent a contract includes multiple promised goods or services, the Company must apply judgment to determine whether the customer can benefit from the goods or services either on their own or together with other resources that are readily available to the customer (the goods or services are distinct) and if the promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract (the goods or services are distinct in the context of the contract). If these criteria are not met, the promised services are accounted for as a single performance obligation. The transaction price is determined based on the consideration that the Company will be entitled to in exchange for transferring goods or services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price, generally utilizing the expected value method. Determining the transaction price requires judgment. If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price basis. Standalone selling price is determined by the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price by taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. Performance obligations are satisfied either over time or at a point in time as discussed in further detail below. In addition, the Company&#8217;s contracts with customers generally do not include significant financing components or non-cash consideration. The Company has elected practical expedients in the accounting guidance that allow for revenue to be recorded in the amount that the Company has a right to invoice, if that amount corresponds directly with the value to the customer of the Company&#8217;s performance to date, and that allow the Company not to disclose related unsatisfied performance obligations. The Company records any amounts that are billed to customers in excess of revenue recognized as deferred revenue and revenue recognized in excess of amounts billed to customers as unbilled receivables.</p></ix:nonNumeric></ix:continuation></div><div style="clear:both;display:table;margin-bottom:27.35pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">96</p></div></div></div>

Estimates are used in accounting for, among other things, revenue recognition, lease right-of-use assets and liabilities, contract loss accruals, excess, slow-moving and obsolete inventories, product warranty accruals, loss accruals on service agreements, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of goodwill and in-process research and development intangible assets, impairment of long-lived assets (including project assets), and contingencies. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates.</p></ix:nonNumeric><ix:nonNumeric contextRef="Duration_11_1_2020_To_10_31_2021_Kn6_1wK4rkmjK-vEPGG-2A" name="us-gaap:ForeignCurrencyTransactionsAndTranslationsPolicyTextBlock" id="Tb_tctYjdlVVUiNthNjZ_JESg" escape="true"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"><i style="text-decoration-line:underline;text-decoration-style:solid;">Foreign Currency Translation</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The translation of the financial statements of FCE Korea&#160;Ltd., FCES GmbH and Versa Power Systems&#160;Ltd. results in translation gains or losses, which are recorded in accumulated other comprehensive loss within stockholders&#8217; equity.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Our Canadian subsidiary, FCE FuelCell Energy&#160;Ltd., is financially and operationally integrated and the functional currency is the U.S. dollar.

As most of the Company&#8217;s leases do not provide an implicit rate, the Company estimated the incremental borrowing rate based on the information available at the date of adoption in determining the present value of lease payments and used the implicit rate when readily determinable. The Company determined incremental borrowing rates through market sources for secured borrowings including relevant industry rates. The Company&#8217;s operating lease ROU assets also include any lease pre-payments and exclude lease incentives. Certain of the Company&#8217;s leases include variable payments, which may vary based upon changes in facts or circumstances after the start of the lease. The Company excludes variable payments from lease ROU assets and lease liabilities to the extent not considered in-substance fixed, and instead, expenses variable payments as incurred. Variable lease expense and lease expense for short term contracts are not material components of lease expense.

CCFC2 and the Company also entered into a Technology License and Access Agreement with Crestmark on February&#160;11, 2020, which provides Crestmark with certain intellectual property license rights to have access to the Company&#8217;s proprietary fuel cell technology, but only for the purpose of maintaining and servicing the Tulare Plant in certain circumstances where the Company is not satisfying its obligations under its service agreement with regard to the maintenance and servicing of the Tulare Plant.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Pursuant to the Tulare Lease, CCFC2 has an obligation to indemnify Crestmark for the amount of any actual reduction in the U.S. Investment Tax Credit anticipated to be realized by Crestmark in connection with the foregoing sale-leaseback transaction. Such obligations would arise as a result of reductions to the value of the underlying fuel cell project as assessed by the IRS. The Company does not believe that any such obligation is probable based on the facts known as of October&#160;31, 2021. The maximum potential future payments that CCFC2 could have to make under these obligations would depend on the difference between the fair values of the fuel cell project sold or financed and the values the IRS would determine as the fair value for the system for purposes of claiming the Investment Tax Credit. The value of the Investment Tax Credit in the sale-leaseback agreements is based on guidelines provided by regulations from the IRS.

tax assets as to whether it is &#8220;more likely than not&#8221; that the deferred tax assets will be realized. In assessing the realizability of our deferred tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies. Based on the projections for future taxable income over the periods in which the deferred tax assets are realizable, management believes that significant uncertainty exists surrounding the recoverability of the deferred tax assets. As a result, we recorded a valuation allowance against our net deferred tax assets.

As a result, the utilization of federal and state NOLs generated prior to October&#160;of 2020 is subject to limitation and a reduction was made in fiscal year 2020 to the carrying balance of the federal and state NOLs to reflect the future limitation on utilization. The Company has updated its analysis of potential ownership changes through October 31, 2021 and concluded that no additional ownership changes have occurred subsequent to October 2020. In addition, the acquisition of Versa in fiscal&#160;year 2013 triggered a Section&#160;382 ownership change at the level of Versa Power System which will limit the future usage of some of the federal and state NOLs that we acquired in that transaction. Accordingly, a valuation allowance has been recorded against the deferred tax asset associated with these attributes to reflect the future limitation on utilization.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Company&#8217;s financial statements reflect expected future tax consequences of uncertain tax positions that the Company has taken or expects to take on a tax return (including a decision whether to file or not file a return in a particular jurisdiction) presuming the taxing authorities&#8217; full knowledge of the position and all relevant facts.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The liability for unrecognized tax benefits as of October&#160;31, 2021 and 2020 was $<ix:nonFraction unitRef="Unit_Standard_USD_fHephQ76nEehLtwQ8lDvnQ" contextRef="As_Of_10_31_2020_3Zwc9umBq0CpkXg3_WsO7Q" decimals="-6" format="ixt:numdotdecimal" name="us-gaap:UnrecognizedTaxBenefits" scale="6" id="Narr_H_dnyrvPgkGs7m7ghsKvfQ"><ix:nonFraction unitRef="Unit_Standard_USD_fHephQ76nEehLtwQ8lDvnQ" contextRef="As_Of_10_31_2021_VYs3lfxfG0Sypeewih4Fpw" decimals="-6" format="ixt:numdotdecimal" name="us-gaap:UnrecognizedTaxBenefits" scale="6" id="Narr_9QrVATH5JUW3deVJlhl69g">0</ix:nonFraction></ix:nonFraction>.

POSCO Energy alleged that it was seeking to inspect these documents for a proper purpose reasonably related to its interests as a stockholder of the Company, including investigating whether the Company&#8217;s Board of Directors and its management breached their fiduciary duties of loyalty, due care, and good faith. POSCO Energy sought an order of the Court permitting POSCO Energy to inspect and copy the demanded books and records, awarding POSCO Energy reasonable costs and expenses, including reasonable attorney&#8217;s fees incurred in connection with the matter, and granting such other and further relief as the Court deemed just and proper. On July 9, 2021, the Court issued a post-trial ruling denying POSCO Energy&#8217;s demand to inspect the Company&#8217;s books and records because POSCO Energy lacked a proper purpose. The Court held that the totality of the circumstances, including the fact that this complaint was the seventh legal action POSCO Energy initiated against the Company within the span of nine months, confirmed that POSCO Energy&#8217;s purpose in initiating the books and records demand and filing the complaint was not proper. As this dispute was resolved by the Court as described above, it did not require resolution pursuant to, and was not part of, the Settlement Agreement described in Note 24. &#8220;Subsequent Events.&#8221;<span style="font-size:12pt;"> </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="font-size:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On September&#160;14, 2020, POSCO Energy filed a complaint in the United States District Court for the Southern District of New York (the &#8220;SD Court&#8221;) alleging that the Company delayed the removal of restrictive legends on certain share certificates held by POSCO Energy in 2018, thus precluding POSCO Energy from selling the shares and resulting in claimed losses in excess of $1.0 million. On September 16, 2021, the SD Court ruled in the Company&#8217;s favor on a motion for summary judgement dismissing all four counts of POSCO Energy&#8217;s complaint regarding share certificates held by POSCO Energy in 2018, but granted POSCO Energy leave to file an amended complaint.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In order to resolve the disputes described above (other than the books and records dispute which was resolved by the Court), on December 20, 2021, the Company entered into the Settlement Agreement with POSCO Energy and KFC.

Although the Company cannot assure the outcome of such Other Legal Proceedings, management presently believes that the result of such Other Legal Proceedings, either individually, or in the aggregate, will not have a material adverse effect on the Company&#8217;s consolidated financial statements, and no material amounts have been accrued in the Company&#8217;s consolidated financial statements with respect to these matters.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Impact of the COVID-19 Pandemic</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">During fiscal&#160;year 2020, the Company launched a proactive response to the escalating COVID-19 outbreak and temporarily suspended operations at its Torrington, Connecticut manufacturing facility in March&#160;2020. The Company also commenced remote work protocol for those employees worldwide that were capable of working from home. The Company took these actions to secure the safety of the Company&#8217;s employees, our corporate community as a whole, and the communities in which our team members live, and to adhere to Centers for Disease Control (CDC) recommendations of social distancing and limited public exposure in connection with the COVID-19 pandemic. All employees that were not able to work from home during the manufacturing facility shutdown due to their job function received full wages and benefits during such time. We did not implement any furlough, layoff or shared work program during such time. The Company resumed manufacturing in June&#160;2020 and the Torrington, Connecticut manufacturing facility employees returned to work. We established a phased-in return to work schedule commencing March&#160;15, 2021 for those employees working from home which was completed in April 2021. We will continue to evaluate our ability to operate in the event of a resurgence of COVID-19 and the advisability of continuing operations based on federal, state and local guidance, evolving data concerning the pandemic and the best interests of our employees, customers and stockholders. In addition, given the continued elevated number of &#160;COVID-19 cases throughout the U.S. as a result of the highly transmissible Delta and Omicron variants, the Company instituted policies to protect its employees and customers &#160;such as a mandatory vaccination policy which required all U.S. employees to be fully vaccinated by November 1, 2021 or seek a qualified religious and/or medical exemption with weekly testing protocols.</p></ix:continuation><a id="_acb58412_9629_4633_8dd4_7fd66edc1977"></a><a id="Tc_VKm-DDQi9Uq-0ypw6muvRQ_1_2"></a><a id="Tc_JxzQB0vEbEGrox3DETxVOQ_2_2"></a><a id="Tc_AytjI0ELdUeWoJ4Fp_iKZQ_2_5"></a><a id="Tc_sX-RK3jLxkOlNqL8fGozxQ_2_8"></a><a id="Tc_ld9q5A-YZUaw_NNXUJ_-0A_3_0"></a><a id="Tc_IHmSLUJW-kuJoU2i3T16lg_3_2"></a><a id="Tc_6B4zLmLq0EacuJn-z-iUeg_3_5"></a><a id="Tc_-A7u6aYNY0WWDKEETZXBZw_3_8"></a><a id="Tc_Jjh-kTS_HkSMKf2O9S9dHQ_4_0"></a><a id="Tc_G9SSjzOYUki0SP77DXQdVg_5_0"></a><a id="Tc_K316iFMbokmjH3eqGz3Lgg_6_0"></a><a id="Tc_F4f6JxlAikeKTz1xWusxHA_6_9"></a><a id="Tc_SPCVoRneX0CSoIvNY7oIYg_7_0"></a><a id="Tc_hkQtOSqREEqp6M8EjKv5HQ_7_3"></a><a id="Tc_hqao19FERk2Bn305iOFTDg_7_6"></a><a id="Tc_2bV_GgZGjEGep3_rfknnGQ_8_0"></a><a id="Tc_Qwq8nttXV02MvH1sMb8y6A_8_3"></a><a id="Tc_bunT7IuApEOeEKrq0U0YfA_8_6"></a><a id="Tc_enn8de9bMUakIz7pM-04uQ_9_0"></a><a id="Tc_4SuzkPE_XkSmyHTLtTgFBw_9_3"></a><a id="Tc_iFIstnQ1rk6j5hHnQBYzjg_9_6"></a><a id="Tc_4qL_EN52BEKQnfTyLrhNXA_10_0"></a><a id="Tc_cfQanuPoqEONR_yHArBBGQ_10_3"></a><a id="Tc_evSLWsMgmka3O-BoMR2sYw_10_6"></a><a id="Tc_LnmaK_PsIEqdj9pVvhnFgA_11_0"></a><a id="Tc_KvXyNGYJZ0KPQRPwdiy4ag_12_0"></a><a id="Tc_w7YTCK59W06SIKdrB-HNBg_12_3"></a><a id="Tc_XG29h0ey3U6BnVKtrzzi0Q_12_9"></a><a id="Tc_LyRocqZqx0Oo-knkGiKVlQ_13_0"></a><a id="Tc_raNwOaiESkGoSutly8pGmA_13_9"></a><a id="Tc_d5OcS5X-3ES4fif9TdudpA_14_0"></a><a id="Tc_Xemw5ikNVEWfsGQyEt8jig_14_9"></a><a id="Tc_hBUfEm6wbkqnUqrTPKFDJQ_15_0"></a><a id="Tc_umzDIXZReUCTfh-_y5ERvg_15_3"></a><a id="Tc_NWa196ymoUOSlKFDuXTEZg_15_9"></a><a id="Tc_N7H52T_1VkmihIeRezTSdw_16_0"></a><a id="Tc_c3E9aqG8jU2DTfwlsEGuQw_16_9"></a><a id="Tc_-P0ijL-bLkKnbthJHoEP5w_17_0"></a><a id="Tc_NObwhbYT0UaPpqbS1vJxsQ_18_0"></a><ix:nonNumeric contextRef="Duration_11_1_2020_To_10_31_2021_Kn6_1wK4rkmjK-vEPGG-2A" name="us-gaap:CashFlowSupplementalDisclosuresTextBlock" id="Tb_atGCwMaDd0qnNvUXUf5oBw" escape="true"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Note&#160;23.

Some of these provisions, including, but not limited to, the inability of stockholders to take action by unanimous written consent, certain advance notice requirements for stockholder proposals and director nominations, supermajority voting provisions with respect to any amendment of voting rights provisions, the filling of vacancies on the board of directors by the affirmative vote of a majority of the remaining directors, and the ability of the board of directors to issue shares of preferred stock and to set the voting rights, preferences and other terms thereof without further stockholder action, may be deemed to have&#160;<font style="font-size:12pt;"><a name="T4"></a></font>an anti-<font style="font-size:12pt;"><a name="T5"></a></font>takeover&#160;effect and may discourage takeover attempts not first approved by the board of directors, including takeovers which stockholders may deem to be in their best interests. If takeover attempts are discouraged, temporary fluctuations in the market price of shares of our common stock, which may result from actual or rumored takeover attempts, may be inhibited. These provisions, together with the ability of the board of directors to issue preferred stock without further stockholder action, could also delay or frustrate the removal of incumbent directors or the assumption of control by our stockholders, even if the removal or assumption would be beneficial to our stockholders. These provisions could also discourage or inhibit a merger, tender offer or proxy contest, even if favorable to the interests of stockholders, and could depress the market price of our common stock. The board of directors believes these provisions are appropriate to protect our interests and the interests of our stockholders. The board of directors has no present plans to adopt any further measures or devices which may be deemed to have an &#8220;<font style="font-size:12pt;"><a name="T6"></a></font>anti-<font style="font-size:12pt;"><a name="T7"></a></font>takeover&#160;effect.&#8221;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"><i style="font-style:italic;">Delaware&#160;</i><font style="font-size:12pt;"><a name="T8"></a></font><i style="font-style:italic;">Anti-</i><font style="font-size:12pt;"><a name="T9"></a></font><i style="font-style:italic;">Takeover&#160;Provisions</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We are subject to Section 203 of the DGCL, which prohibits a publicly-held Delaware corporation from engaging in a &#8220;business combination,&#8221; except under certain circumstances, with an &#8220;interested stockholder&#8221; for a period of three years following the date such person became an &#8220;interested stockholder&#8221; unless:</p><table border="0" cellpadding="0" cellspacing="0" style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:12pt;line-height:1.12;margin-bottom:6pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"></td><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:13pt;padding:0pt;">&#9679;</td><td style="padding:0pt;"><font style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;line-height:1.12;text-align:justify;">before such person became an interested stockholder, the board of directors of the corporation approved either the business combination or the transaction that resulted in the interested stockholder becoming an interested stockholder;</font></td></tr></table><table border="0" cellpadding="0" cellspacing="0" style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:12pt;line-height:1.12;margin-bottom:6pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"></td><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:13pt;padding:0pt;">&#9679;</td><td style="padding:0pt;"><font style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;line-height:1.12;text-align:justify;">upon the consummation of the transaction that resulted in the interested stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding shares held by directors who are also officers of the corporation and shares held by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or</font></td></tr></table><table border="0" cellpadding="0" cellspacing="0" style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:12pt;line-height:1.12;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"></td><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:13pt;padding:0pt;">&#9679;</td><td style="padding:0pt;"><font style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;line-height:1.12;text-align:justify;">at or following the time such person became an interested stockholder, the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of stockholders (and not by written consent) by the affirmative vote of the holders of at least 66</font><sup style="font-family:'Times New Roman','Times','serif';font-size:7.5pt;font-style:normal;font-weight:normal;text-align:justify;vertical-align:top;">2/3</sup><font style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;line-height:1.12;text-align:justify;">% of the outstanding voting stock of the corporation which is not owned by the interested stockholder.</font></td></tr></table><div style="margin-top:6pt;"></div><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The term &#8220;interested stockholder&#8221; generally is defined as a person who, together with affiliates and associates, owns, or, within the three years prior to the determination of interested stockholder status, owned, 15% or more of a corporation&#8217;s outstanding voting stock. The term &#8220;business combination&#8221; includes mergers, asset or stock sales and other similar transactions resulting in a financial benefit to an interested stockholder. Section 203 makes it more difficult for an &#8220;interested stockholder&#8221; to effect various business combinations with a corporation for a three-year period. The existence of this provision would be expected to have an&#160;<font style="font-size:12pt;"><a name="T10"></a></font>anti-<font style="font-size:12pt;"><a name="T11"></a></font>takeover&#160;effect with respect to transactions not approved in advance by the board of directors, including discouraging attempts that might result in a premium over the market price for the shares of our common stock held by stockholders. A Delaware corporation may &#8220;opt out&#8221; of Section 203 with an express provision in its original certificate of incorporation or any amendment thereto. Our Certificate of Incorporation does not contain any such exclusion.</p></div><div style="clear:both;display:table;margin-bottom:30pt;min-height:36pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;text-align:center;margin:0pt;"><font style="font-size:10pt;">5</font></p><p style="font-family:'Arial','Helvetica','sans-serif';font-size:8pt;margin:0pt 0pt 12pt 0pt;"><font style="visibility:hidden;">&#8203;</font></p></div></div></div><hr style="background-color:#000000;clear:both;color:#000000;height:2pt;line-height:0;margin-left:11.76%;margin-right:11.76%;margin-top:30pt;page-break-after:avoid;width:76.47%;border-width:0;"></body></html>

Cost is determined using the first-in, first-out cost method. Included in our inventory balance are used modules that are brought back into inventory upon installation of new modules. When a new module is installed, a determination is made as to whether the module has remaining useful life or should be scrapped and materials recycled. Modules that are deemed to have remaining useful life are put into inventory at an estimated value based on the expected remaining life of the module and its projected output. In certain circumstances, we will make advance payments to vendors for future inventory deliveries.

Such development costs are generally incurred prior to entering into a definitive sales or long-term financing agreement for the project. Project assets also include capitalized costs for fuel cell projects which are the subject of a sale-leaseback transaction with PNC Energy Capital, LLC (&#8220;PNC&#8221;) or Crestmark Equipment Finance, a division of MetaBank (&#8220;Crestmark&#8221;). Project asset costs include costs for developing and constructing a complete turn-key fuel cell project. Development costs can include legal, consulting, permitting, interconnect, and other similar costs. To the extent we enter into a definitive sales agreement, we expense project assets to cost of sales after the respective project asset is sold to a customer and all revenue recognition criteria have been met.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"><i style="text-decoration-line:underline;text-decoration-style:solid;">Property, Plant and Equipment</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Property, plant and equipment are stated at cost, less accumulated depreciation which is recorded based on the straight-line method over the estimated useful lives of the respective assets.

Under Topic 606: <i style="font-style:italic;">Revenue from Contracts with Customers, </i>the amount of revenue recognized for any goods or services reflects the consideration that the Company expects to be entitled to receive in exchange for those goods and services. To achieve this core principle, the Company applies the following five-step approach: (1)&#160;identify the contract with the customer; (2)&#160;identify the performance obligations in the contract; (3)&#160;determine the transaction price; (4)&#160;allocate the transaction price to performance obligations in the contract; and (5)&#160;recognize revenue when or as a performance obligation is satisfied.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">A contract is accounted for when there has been approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Performance obligations under a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct and are distinct in the context of the contract. In certain instances, the Company has concluded distinct goods or services should be accounted for as a single performance obligation that is a series of distinct goods or services that have the same pattern of transfer to the customer. To the extent a contract includes multiple promised goods or services, the Company must apply judgment to determine whether the customer can benefit from the goods or services either on their own or together with other resources that are readily available to the customer (the goods or services are distinct) and if the promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract (the goods or services are distinct in the context of the contract). If these criteria are not met, the promised services are accounted for as a single performance obligation. The transaction price is determined based on the consideration that the Company will be entitled to in exchange for transferring goods or services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price, generally utilizing the expected value method. Determining the transaction price requires judgment. If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price basis. Standalone selling price is determined by the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price by taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. Performance obligations are satisfied either over time or at a point in time as discussed in further detail below. In addition, the Company&#8217;s contracts with customers generally do not include significant financing components or non-cash consideration. The Company has elected practical expedients in the accounting guidance that allow for revenue to be recorded in the amount that the Company has a right to invoice, if that amount corresponds directly with the value to the customer of the Company&#8217;s performance to date, and that allow the Company not to disclose related unsatisfied performance obligations. The Company records any amounts that are billed to customers in excess of revenue recognized as deferred revenue and revenue recognized in excess of amounts billed to customers as unbilled receivables.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Revenue streams are classified as follows:</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">Product.</b> Includes the sale of completed project assets, sale and installation of fuel cell power platforms including site engineering and construction services, and the sale of modules, balance of plant (&#8220;BOP&#8221;) components and spare parts to customers.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">Service.</b> Includes performance under long-term service agreements for power platforms owned by third parties.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">License and royalty. </b>Includes license fees and royalty income from the licensure of intellectual property.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">Generation.</b> Includes the sale of electricity under PPAs and utility tariffs from project assets retained by the Company.

The relative stand-alone selling price is estimated and is used as the basis for allocation of the contract consideration. Revenue is recognized upon the satisfaction of the performance obligations, which includes the transfer of control of the project asset to the customer, which is when the contract is signed and the PPA is assigned to the customer. See below for further discussion regarding revenue recognition for service agreements. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Contractual payments related to the sale of the project asset and assignment of the PPA are generally received up-front.

The Company recorded license revenue of $4.0 million in association with this agreement for the fiscal&#160;year ended October&#160;31, 2020 which revenue was considered at a point-in-time upon the signing of the contract as the license is considered functional intellectual property because it has standalone functionality.

Revenue is recognized when electricity has been delivered based on the amount of electricity delivered at rates specified under the contracts, assuming all other revenue recognition criteria are met.

The Company has determined that it is the primary beneficiary in the Groton Partnership for accounting purposes. The Company has considered the provisions within the financing-related agreements (including the limited liability company agreement for the Groton Partnership) which grant the Company power to manage and make decisions affecting the operations of the Groton Partnership. The Company considers the rights granted to East West Bank under the agreements to be more protective in nature than participatory. Therefore, the Company has determined under the power and benefits criterion of Accounting Standards Codification 810, <i style="font-style:italic;">Consolidations </i>that it is the primary beneficiary of the Groton Partnership. As the primary beneficiary, the Company consolidates in its consolidated financial statements the financial position, results of operations and cash flows of the Groton Partnership, and all intercompany balances and transactions between the Company and the Groton Partnership are eliminated in the consolidated financial statements. The Company recognized East West Bank&#8217;s share of the net assets of the Groton Partnership, which is $3.0 million as of October 31, 2021, as a noncontrolling interest in mezzanine equity on its Consolidated Balance Sheet and will continue to do so until the conditional withdrawal period lapses upon commencement of operations. Upon commencement of operations of the related project asset, the Company expects to allocate profits and losses to the noncontrolling interest under the hypothetical liquidation at book value ("HLBV") method. HLBV is a balance sheet-oriented approach for allocating net income or loss to the noncontrolling interest when there is a complex structure, such as the partnership flip structure.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"><i style="text-decoration-color:#000000;text-decoration-line:underline;text-decoration-style:solid;">Sale-Leaseback Accounting</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Company, through certain wholly-owned subsidiaries, has entered into sale-leaseback transactions for commissioned project assets where we have entered into a PPA with a customer who is both the site host and end user of the power. Due to the Company not meeting criteria to account for the transfer of the project assets as a sale, sale accounting is precluded. Accordingly, the Company uses the financing method to account for these transactions.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Under the financing method of accounting for a sale-leaseback, the Company does not derecognize the project assets and does not recognize as revenue any of the sale proceeds received from the lessor that contractually constitutes payment to acquire the assets subject to these arrangements. Instead, the sale proceeds received are accounted for as financing obligations and leaseback payments made by the Company are allocated between interest expense and a reduction to the financing obligation. Interest on the financing obligation is calculated using the Company&#8217;s incremental borrowing rate at the inception of the arrangement on the outstanding financing obligation. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"><i style="text-decoration-line:underline;text-decoration-style:solid;">Service Expense Recognition</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">We warranty our products for a specific period of time against manufacturing or performance defects.

Under the terms of these service agreements, the power platform must meet a minimum operating output during the term. If the minimum output falls below the contract requirement, we may be subject to performance penalties or may be required to repair and/or replace the customer&#8217;s fuel cell module.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Company records loss accruals for service agreements when the estimated cost of future module exchanges and maintenance and monitoring activities exceeds the remaining unrecognized contract value. Estimates for future costs on service agreements are determined by a number of factors including the estimated remaining life of the module, used replacement modules available and future operating plans for the power platform. Our estimates are performed on a contract by contract basis and include cost assumptions based on what we anticipate the service requirements will be to fulfill obligations for each contract.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">At the end of our service agreements, customers are expected to either renew the service agreement or, based on the Company&#8217;s rights to title of the module, the module will be returned to the Company as the platform is no longer being maintained.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"><i style="text-decoration-line:underline;text-decoration-style:solid;">Research and Development Costs</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">We perform both customer-sponsored research and development projects based on contractual agreements with customers and company-sponsored research and development projects.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Costs incurred for customer-sponsored projects include manufacturing and engineering labor, applicable overhead expenses, materials to build and test prototype units and other costs associated with customer-sponsored research and development contracts.

Estimates are used in accounting for, among other things, revenue recognition, lease right-of-use assets and liabilities, contract loss accruals, excess, slow-moving and obsolete inventories, product warranty accruals, loss accruals on service agreements, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of goodwill and in-process research and development intangible assets, impairment of long-lived assets (including project assets), and contingencies. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"><i style="text-decoration-line:underline;text-decoration-style:solid;">Foreign Currency Translation</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The translation of the financial statements of FCE Korea&#160;Ltd., FCES GmbH and Versa Power Systems&#160;Ltd. results in translation gains or losses, which are recorded in accumulated other comprehensive loss within stockholders&#8217; equity.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Our Canadian subsidiary, FCE FuelCell Energy&#160;Ltd., is financially and operationally integrated and the functional currency is the U.S. dollar.

The contract assets relate to the Company&#8217;s rights to consideration for work completed but not billed. These amounts are included on a separate line item as Unbilled receivables, and balances expected to be billed later than one&#160;year from the balance sheet date are included within Other assets on the accompanying Consolidated Balance Sheets. The net change in contract assets represents amounts recognized as revenue offset by customer billings. &#160;For the years ended October 31, 2021 and 2020, a total of $5.2 million and $5.9 million, respectively, was transferred to accounts receivable from contract assets recognized at the beginning of the period.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Contract&#160;liabilities&#160;as&#160;of&#160;October&#160;31,&#160;2021&#160;and&#160;2020&#160;were&#160;$36.7&#160;million&#160;and&#160;$41.9 million, respectively. The contract liabilities relate to the advance billings to customers for services that will be recognized over time and in some instances for deferred revenue relating to license performance obligations that will be recognized at a future point in time. The Company discontinued revenue recognition of the deferred license revenue related to the License Agreements in July 2020 given the then pending arbitrations. As of October&#160;31, 2021 and 2020, $22.2 million related to the License Agreements is included within Long-term deferred revenue on the accompanying Consolidated Balance Sheets. As a result of the Settlement Agreement and the anticipated sale of modules to KFC under the Settlement Agreement (Refer to Note 24. &#8220;Subsequent Events&#8221; for additional details), the Company will evaluate the future revenue recognition of this deferred revenue in the first quarter of fiscal year 2022. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The net change in contract liabilities represents customer billings offset by revenue recognized. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"><i style="font-style:italic;">Remaining Performance Obligations</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Remaining performance obligations are the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied. As of October&#160;31, 2021, the Company&#8217;s total remaining performance obligations for service agreements was $125.9 million, for license agreements was $22.2 million and for Advanced Technologies contracts was $40.8 million. Service revenue in periods in which there are no module exchanges is expected to be relatively consistent from period to period, whereas module exchanges will result in an increase in revenue when replacements occur.</p><span></span>

BFC owns a 14.9 MW fuel cell park in Bridgeport, Connecticut (the &#8220;Bridgeport Fuel Cell Project&#8221;), which the Company originally developed and constructed and has been operating for Dominion Generation,&#160;Inc. under a service agreement since December&#160;2013.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On May&#160;9, 2019, FuelCell Finance closed on the purchase of BFC for a total cash purchase price of $35.5 million, subject to a dollar-for-dollar post-closing adjustment to the extent that the closing working capital was greater or less than $1.0 million (the &#8220;BFC Purchase Price&#8221;).&#160;The Company recorded a working capital adjustment of $0.6 million, which has been included in the BFC Purchase Price. Certain balance sheet accounts as of the transaction date, May&#160;9, 2019, relating to the Bridgeport Fuel Cell Project service agreement (accounts receivable of $2.7 million, unbilled receivables of $15.3 million and accrued performance guarantees of $1.3 million) were settled in connection with the acquisition and accordingly were included in the consideration for the acquisition.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The acquisition was funded by loans from Fifth Third Bank, Liberty Bank and Connecticut Green Bank (refer to Note&#160;14. &#8220;Debt and Financing Obligations&#8221; for more information).&#160;The balance of the financing for the acquisition was funded by the $15 million of restricted cash on hand that was tied to the Bridgeport Fuel Cell Project and released at closing.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">ASC Topic 805, &#8220;Business Combinations&#8221; states that a business is an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs, or other economic benefits directly to investors or other owners, members, or participants.&#160;As the acquisition did not meet the definition of a business combination under ASC 805, the Company accounted for the transaction as an asset acquisition. In an asset acquisition, goodwill is not recognized, but rather any excess consideration transferred over the fair value of the net assets acquired is allocated on a relative fair value basis to the identifiable net assets. The Company determined the estimated fair values of net assets acquired using Level 3 inputs after review and consideration of relevant information, including discounted cash flows, quoted market prices and estimates made by management. The acquisition of BFC also included a PPA with Connecticut Light and Power that has favorable terms relative to market, a land lease with the City of Bridgeport, and working capital.&#160;A pre-existing service agreement was determined to be priced similar to current market rates and no gain or loss was recorded. A total of $38.8 million of consideration was allocated to the fuel cell power platform installation, which is recorded in Project Assets, a total of $12.3 million of consideration was allocated to the PPA, which is recorded as an intangible asset, and the remaining consideration was allocated to the acquired working capital.&#160;The project asset and PPA intangible asset will be depreciated and amortized over their respective useful lives.&#160;Additionally, the land lease with the City of Bridgeport was not assigned any consideration due to its insignificant value.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">The major depreciable assets of the Bridgeport Fuel Cell Project are the fuel cell modules, which are being depreciated over their estimated remaining useful lives of approximately <span style="-sec-ix-hidden:Hidden_Hf9iFhSmTkmn6qlHjRmHeg;"><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">one</span></span> to seven years, and BOP assets, which are being depreciated over their estimated remaining useful lives of approximately 15 years.

Tax Equity Financing</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">The Company closed on a tax equity financing transaction in August 2021 with East West Bank for the 7.4 MW Groton Project located on the U.S. Navy Submarine Base in Groton, CT, also known as the Submarine Force. East West Bank&#8217;s tax equity commitment totals $15 million.&#160;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">This transaction was structured as a &#8220;partnership flip&#8221;, which is a structure commonly used by tax equity investors in the financing of renewable energy projects. Under this partnership flip structure, a partnership, in this case Groton Station Fuel Cell Holdco, LLC (the &#8220;Groton Partnership&#8221;) was organized to acquire from FuelCell Energy Finance II, LLC, a wholly-owned subsidiary of the Company, all outstanding equity interests in Groton Station Fuel Cell, LLC (the &#8220;Groton Project Company&#8221;) which in turn owns the Groton Project and is the party to the power purchase agreement and all project agreements. At the closing of the transaction, the Groton Partnership is owned by East West Bank, holding Class A Units, and Fuel Cell Energy Finance Holdco, LLC, a subsidiary of FuelCell Energy Finance, LLC, holding Class B Units. &#160;The acquisition of the Groton Project Company by the Groton Partnership was funded in part by an initial draw from East West Bank and funds contributed downstream to the Groton Partnership by the Company. The initial closing occurred on August 4, 2021, upon the satisfaction of certain conditions precedent (including the receipt of an appraisal and confirmation that the Groton Project would be eligible for the investment tax credit under Section 48 of the Internal Revenue Code of 1986, as amended). &#160;In connection with the initial closing, the Company was able to draw down $3.0 million, of which approximately $0.8 million was used to pay closing costs including appraisal fees, title insurance expenses and legal and consulting fees. The Company is eligible to draw the remaining amount of the commitment, approximately $12 million, once the Groton Project achieves commercial operation. &#160;When such funds are drawn down, the funds will be distributed upstream to the Company, as a reimbursement of prior construction costs incurred by the Company. The Company recognized a loss of $30 thousand for the fiscal year ended October 31, 2021 which is attributable to the noncontrolling interest reflecting the 1% conditional withdrawal.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Under most partnership flip structures, tax equity investors agree to receive a minimum target rate of return, typically on an after-tax basis. Prior to receiving a contractual rate of return or a date specified in the contractual arrangements, East West Bank will receive substantially all of the non-cash value attributable to the Groton Project, which includes accelerated depreciation and Section 48(a) investment tax credits; however, the Company will receive a majority of the cash distributions (based on the operating income of the Groton Project), which are paid quarterly. After East West Bank receives its contractual rate of return, the Company will receive approximately 95% of the cash and tax allocations. The </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Company (through a separate wholly owned entity) may enter into a back leverage debt financing transaction and use the cash distributions from the Groton Partnership to service the debt.</p><span></span>

In addition, the Company has elected the practical expedients to not separate lease and non-lease components, to use hindsight in determining the lease terms and impairment of ROU assets, and to not apply the Standard&#8217;s recognition requirements to short-term leases with a term of 12&#160;months or less.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The adoption of the Standard did not have a material effect on the Company&#8217;s Consolidated Statements of Operations and Comprehensive Loss or Consolidated Statement of Cash Flows. Upon adoption, the Company recorded a $10.3 million operating lease ROU asset and a $10.1 million operating lease liability. The adoption of the New Lease Accounting Standard had no impact on accumulated deficit.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Company enters into operating and finance lease agreements for the use of real estate, vehicles, information technology equipment, and certain other equipment. We determine if an arrangement contains a lease at inception, which is the date on which the terms of the contract are agreed to and the agreement creates enforceable rights and obligations. The impacts of accounting for operating leases are included in Operating lease right-of-use assets, Operating lease liabilities, and Long-term operating lease liabilities in the Company&#8217;s Consolidated Balance Sheets. Finance leases are not considered significant to the Company&#8217;s Consolidated Balance Sheets or Consolidated Statements of Operations and Comprehensive Loss. Finance lease ROU assets at October&#160;31, 2021 and 2020 of $0.1 million and $0.04 million, respectively, are included in Property, plant and equipment, net in the Company&#8217;s Consolidated Balance Sheets. Finance lease liabilities at October&#160;31, 2021 and 2020 of $0.1 million and $0.04 million, respectively, are included in Current portion of long-term debt and <span style="-sec-ix-hidden:Hidden_705130pvx0GZM-jE7WnSTQ;"><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">Long-term debt</span></span> and other liabilities in the Company&#8217;s Consolidated Balance Sheets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">ROU assets represent the Company&#8217;s right to use an underlying asset for the lease term and lease liabilities represent the present value of the Company&#8217;s obligation to make lease payments arising from the lease over the lease term at the commencement date of the lease (or November&#160;1, 2019 for leases existing upon the adoption of ASC 842). As most of the Company&#8217;s leases do not provide an implicit rate, the Company estimated the incremental borrowing rate based on the information available at the date of adoption in determining the present value of lease payments and used the implicit rate when readily determinable. The Company determined incremental borrowing rates through market sources for secured borrowings including relevant industry rates. The Company&#8217;s operating lease ROU assets also include any lease pre-payments and exclude lease incentives. Certain of the Company&#8217;s leases include variable payments, which may vary based upon changes in facts or circumstances after the start of the lease. The Company excludes variable payments from lease ROU assets and lease liabilities to the extent not considered in-substance fixed, and instead, expenses variable payments as incurred. Variable lease expense and lease expense for short term contracts are not material components of lease expense. The Company&#8217;s leases generally have remaining lease terms of <span style="-sec-ix-hidden:Hidden_Q0t8OangsUy1qIQciHf15w;"><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">1</span></span> to 26 years, some of which include options to extend leases. The exercise of lease renewal options is at the Company&#8217;s sole discretion and the Company&#8217;s lease ROU assets and liabilities reflect only the options the Company is reasonably certain that it will exercise. We do not have leases with residual value guarantees or similar covenants.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Operating lease costs for the&#160;years ended October&#160;31, 2021 and 2020 was $1.5 million. As of October&#160;31, 2021, the weighted average remaining lease term (in&#160;years) was approximately 20 years and the weighted average discount rate was 8.15%. Lease payments made during the&#160;years ended October&#160;31, 2021 and 2020 totaled $1.2 million and $1.0 million, respectively.</p><p style="font-family:'Times New

style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;">On August 25, 2021, an indirect wholly-owned subsidiary of the Company, San Bernardino Fuel Cell, LLC (&#8220;SBFC&#8221;), entered into a Purchase and Sale Agreement (the &#8220;San Bernardino Purchase Agreement&#8221;) and an Equipment Lease Agreement (the &#8220;San Bernardino Lease&#8221;) with Crestmark Equipment Finance (&#8220;Crestmark&#8221;). Under these agreements, SBFC sold the 1.4 MW biogas fueled fuel cell power plant (the &#8220;San Bernardino Plant&#8221;) located at the San Bernardino wastewater treatment plant in San Bernardino, California to Crestmark for a purchase price of $10.2 million and then leased the San Bernardino Plant back from Crestmark. SBFC sells the power produced by the San Bernardino Plant to a third party under a twenty-year PPA (the &#8220;San Bernardino PPA&#8221;). </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The San Bernardino Lease has an initial term of ten years but may be extended at the option of SBFC. An initial rental down payment and one quarter&#8217;s rent totaling $2.2 million was paid using the proceeds from the sale of the San Bernardino Plant. Lease payments are expected to be funded with proceeds from the sale of power under the San Bernardino PPA on a quarterly basis. As a result of the sale-leaseback transaction, the remaining lease payments due over the term of the San Bernardino Lease were approximately $5.3 million immediately following the transaction and as of October&#160;31, 2021.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;">Reserves covering debt service and future module replacement totaling $2.5 million were also deducted from the proceeds from the sale of the San Bernardino Plant and will be classified as restricted cash of the Company until such time as it meets its performance obligations (such as servicing the San Bernardino Plant and providing module exchanges) under the Long Term Service Agreement for the San Bernardino Plant. The Company&#8217;s net unrestricted cash proceeds from the transaction totaled approximately $5.3 million, which is the purchase price less the initial rent payments, debt and module reserves, and taxes and transaction fees. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">In addition, SBFC and Crestmark entered into an Assignment Agreement on August 25, 2021 (the &#8220;San Bernardino Assignment Agreement&#8221;) and FuelCell Finance (a wholly-owned subsidiary of the Company and the direct parent of SBFC) and Crestmark entered into a Pledge Agreement on August 25, 2021 (the &#8220;San Bernardino Pledge Agreement&#8221;) pursuant to which agreements collateral was provided to Crestmark to secure SBFC&#8217;s obligations under the San Bernardino Lease which includes a security interest in (i) certain agreements relating to the sale-leaseback transaction, (ii) the revenues with respect to the San Bernardino Plant, (iii) a cash module replacement reserve for the San Bernardino Plant, and (iv) FuelCell Finance&#8217;s equity interest in SBFC. SBFC and the Company also entered into a Technology License and Access Agreement with Crestmark on August 25, 2021, which provides Crestmark with certain intellectual property license rights to have access to the Company&#8217;s proprietary fuel cell technology, but only for the purpose of maintaining and servicing the San Bernardino Plant in certain circumstances in which the Company is not satisfying its obligations under its service agreement with regard to the maintenance and servicing of the San Bernardino Plant.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Pursuant to the San Bernardino Lease, SBFC has an obligation to indemnify Crestmark for the amount of any actual reduction in the U.S. investment tax credit (&#8220;ITC&#8221;) anticipated to be realized by Crestmark in connection with this sale-leaseback transaction. Such obligation would arise as a result of reductions to the value of the underlying fuel cell project as assessed by the U.S. Internal Revenue Service (&#8220;IRS&#8221;). The Company does not believe that any such obligation is probable based on the facts known as of October 31, 2021. The maximum potential future payments that SBFC could be required to make as a result of this obligation would depend on the difference between the fair value of the fuel cell project sold or financed and the value the IRS would determine as the fair value of the project for purposes of claiming the ITC. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">The value of the ITC in the sale-leaseback agreements is based on guidelines provided by regulations from the IRS.

Under these agreements, CCFC2 sold the 2.8 MW biogas fueled fuel cell power plant (the &#8220;Tulare Plant&#8221;) located at the Tulare wastewater treatment plant in Tulare, California to Crestmark for a purchase price of $14.4 million and then leased the Tulare Plant back from Crestmark. CCFC2 sells the power produced by the Tulare Plant to a third party under a twenty-year PPA (the &#8220;Tulare PPA&#8221;). The Tulare Lease includes an end of term option for CCFC2 to repurchase the transferred assets. The repurchase clause precluded sale accounting since there are no alternative assets substantially the same as the transferred assets readily available in the marketplace. As such, the transaction is a failed sale-leaseback transaction that is accounted for as a financing transaction.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Tulare Lease has an initial term of ten years but may be extended at the option of CCFC2.

Company and certain of its affiliates as guarantors entered into a Credit Agreement (as amended from time to time, the &#8220;Orion Credit Agreement&#8221;) with Orion Energy Partners Investment Agent, LLC, as Administrative Agent and Collateral Agent (the &#8220;Orion Agent&#8221;), and certain lenders affiliated with the Orion Agent for a $200.0 million senior secured credit facility (the &#8220;Orion Facility&#8221;), structured as a delayed draw term loan to be provided by the lenders primarily to fund certain of the Company&#8217;s construction and related costs for fuel cell projects meeting the requirements of the Orion Facility. Under the Orion Credit Agreement, each lender funded its commitments less 2.50% of the aggregate principal amount of the loans funded by such lender (the &#8220;Loan Discount&#8221;).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On October&#160;31, 2019, the Company drew down $14.5 million (the &#8220;Initial Funding&#8221;) and received $14.1 million, after taking into account a Loan Discount of $0.4 million. On October&#160;31, 2019, in connection with the Initial Funding, the Company issued warrants to the lenders under the Orion Credit Agreement to purchase up to a total of 6,000,000 shares of the Company&#8217;s common stock, at an exercise price of $0.310 per share (the &#8220;Initial Funding Warrants&#8221;).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On November&#160;22, 2019, a second draw (the &#8220;Second Funding&#8221;) of $65.5 million, funded by&#160;Orion Energy Credit Opportunities Fund II,&#160;L.P., Orion Energy Credit Opportunities Fund II GPFA,&#160;L.P., Orion Energy Credit Opportunities </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Fund II PV,&#160;L.P., and Orion Energy Credit Opportunities FuelCell Co-Invest,&#160;L.P. (as the lenders under the Orion Credit Agreement), was made to fully repay certain outstanding third party debt of the Company, including the outstanding construction loan from Fifth Third Bank with respect to the Groton Project and the outstanding loan from Webster Bank with respect to the CCSU Project, as well as to fund remaining going forward construction costs and anticipated capital expenditures relating to the Groton Project (a 7.4 MW project), the LIPA Yaphank Solid Waste Management Project (a 7.4 MW project), and the Tulare BioMAT Project (a 2.8 MW project). The Company received $63.9 million in the Second Funding after taking into account a Loan Discount of $1.6 million as described above. Also in conjunction with the Second Funding, the Company issued to the lenders warrants to purchase up to a total of 14.0 million shares of the Company&#8217;s common stock, with an initial exercise price with respect to 8.0 million of such shares of $0.242 per share and with an initial exercise price with respect to 6.0 million of such shares of $0.620 per share (the &#8220;Second Funding Warrants&#8221;).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Under the Orion Credit Agreement, cash interest of 9.9% per annum was paid quarterly. In addition to the cash interest, payment-in-kind interest of 2.05% per annum accrued which was added to the outstanding principal balance of the Orion Facility but was paid quarterly in cash to the extent of available cash after payment of the Company&#8217;s operating expenses and the funding of certain reserves for the payment of outstanding indebtedness to the State of Connecticut and Connecticut Green Bank.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Outstanding principal under the Orion Facility was to be amortized on a straight-line basis over a seven-year term with the initial payment due 21 business&#160;days after the end of the first quarter of fiscal&#160;year 2021. The maturity date of the Orion Facility was October&#160;31, 2027. The Orion Facility contained an administrative fee of $0.1 million per&#160;year paid on a quarterly basis and also included a prepayment premium of up to 35%.

Upon entering into the secondary facility loan commitment, the Company owed the lenders under the Orion Credit Agreement an option premium of $1.0 million. The Company paid the $1.0 million option premium during the&#160;year ended October&#160;31, 2020 and recorded the amount as interest expense.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On November&#160;30, 2020, the Company, its subsidiary guarantors, and the Orion Agent entered into a payoff letter with respect to the Orion Credit Agreement (the &#8220;Orion Payoff Letter&#8221;). Pursuant to the Orion Payoff Letter, on December&#160;7, 2020, the Company paid a total of $87.3 million to the Orion Agent, representing the outstanding principal, accrued but unpaid interest, prepayment premium, fees, costs and other expenses due and owing under the Orion Facility and the Orion Credit Agreement and related loan documents, in full repayment of the Company&#8217;s outstanding indebtedness under the Orion Facility and the Orion Credit Agreement and related loan documents. In accordance with the Orion Payoff Letter, the aggregate prepayment premium set forth in the Orion Credit Agreement was reduced from approximately $14.9 million to $4.0 million and the Orion Agent, on behalf of itself and the lenders, agreed that any portion of the prepayment premium that would otherwise be required to be paid pursuant to the Orion Credit Agreement in excess of $4.0 million was waived by the Orion Agent and the lenders. The Company expensed the remaining deferred finance costs and debt discount of $7.1 million. The Company has classified the $4.0 million prepayment premium and the deferred finance costs and debt discount expense as Loss on extinguishment of debt and financing obligation on the Consolidated Statements of Operations and Comprehensive Loss.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Concurrently with the Orion Agent&#8217;s receipt of full payment pursuant to the Orion Payoff Letter, the Orion Agent released all of the collateral from the liens granted under the security documents associated with the Orion Facility (which included the release of $11.2 million of restricted cash to the Company, which became unrestricted cash), and the Company and its subsidiaries were unconditionally released from their respective obligations under the Orion Credit Agreement (and related loan documents) and the Orion Facility without further action. With the termination of the Orion Facility and the Orion Credit Agreement and related loan documents, the lenders no longer have the right to appoint representatives to attend the Company&#8217;s Board of Director meetings as observers.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Connecticut Green Bank Loans</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">As of October&#160;31, 2019, the Company had a long-term loan agreement with the Connecticut Green Bank, providing the Company with a loan of $1.8 million (the &#8220;Green Bank Loan Agreement&#8221;). On and effective as of December&#160;19, 2019, the Company and Connecticut Green Bank entered into an amendment to the Green Bank Loan Agreement (the &#8220;Green Bank Amendment&#8221;). Upon the execution of the Green Bank Amendment on December&#160;19, 2019, Connecticut Green Bank made an additional loan to the Company in the aggregate principal amount of $3.0 million (the &#8220;December&#160;2019 Loan&#8221;), which was to be used (i)&#160;first, to pay closing fees related to the May&#160;9, 2019 acquisition of the Bridgeport Fuel Cell Project and the Subordinated Credit Agreement (as defined below), other fees and interest, and (ii)&#160;thereafter, for general corporate purposes.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Green Bank Amendment provides that, until such time as the loan (which includes both the outstanding principal balance of the original loan under the Green Bank Loan Agreement and the outstanding principal amount of the December&#160;2019 Loan) has been repaid in its entirety, interest on the outstanding balance of the loan shall accrue at a rate of 8% per annum, payable by the Company on a&#160;monthly basis in arrears. Interest payments made by the Company after the date of the Green Bank Amendment are to be applied first to interest that has accrued on the outstanding principal balance of the original loan under the Green Bank Loan Agreement and then to interest that has accrued on the December&#160;2019 Loan.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Green Bank Amendment also modifies the repayment and mandatory prepayment terms and extends the maturity date set forth in the original Green Bank Loan Agreement. Under the Green Bank Amendment, to the extent that excess cash flow reserve funds under the BFC Credit Agreement (as defined below) are eligible for disbursement to Bridgeport Fuel Cell, LLC pursuant to Section&#160;6.23(c)&#160;of the BFC Credit Agreement, such funds are to be paid to Connecticut Green Bank until the loans are repaid in full. The Green Bank Amendment further provides that any unpaid balance of the loan and all other obligations due under the Green Bank Loan Agreement will be due and payable on May&#160;9, 2026. Finally, with respect to mandatory prepayments, the Green Bank Amendment provides that, when the Company has closed on the subordinated project term loan pursuant to the Commitment Letter, dated February&#160;6, 2019, issued by Connecticut Green Bank to <span style="background:#ffffff;">Groton Station Fuel Cell, LLC (&#8220;Groton Fuel Cell&#8221;)</span> to provide a subordinated project term loan to Groton Fuel Cell in the amount of $5.0 million, the Company will be required to prepay to Connecticut Green Bank the lesser of any then outstanding amount of the December&#160;2019 Loan and the amount of the subordinated project term loan actually advanced by Connecticut Green Bank. The balance under the original Green Bank Loan Agreement and the December&#160;2019 Loan as of October&#160;31, 2021 was $4.8 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Bridgeport Fuel Cell Project Loans</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On May&#160;9, 2019, in connection with the closing of the purchase of the membership interests of Bridgeport Fuel Cell, LLC (&#8220;BFC&#8221;) (and the 14.9 MW Bridgeport Fuel Cell Project), BFC entered into a subordinated credit agreement with the Connecticut Green Bank whereby Connecticut Green Bank provided financing in the amount of $6.0 million (the &#8220;Subordinated Credit Agreement&#8221;). This $6.0 million consisted of $1.8 million in incremental funding that was received by BFC and $4.2 million of funding previously received by FuelCell Energy,&#160;Inc. with respect to which BFC became the primary obligor. As security for the Subordinated Credit Agreement, Connecticut Green Bank received a perfected lien, subordinated and second in priority to the liens securing the $25.0 million loaned under the BFC Credit Agreement (as defined below), in all of the same collateral securing the BFC Credit Agreement. The interest rate under the Subordinated Credit Agreement is 8% per annum. Principal and interest are due&#160;monthly in amounts sufficient to fully amortize the loan over an 84-month period ending in May&#160;2026. The Subordinated Credit Agreement contains a debt coverage ratio which is required to be maintained and may not be less than 1.10 as of the end of each fiscal quarter, beginning with the quarter ended July&#160;31, 2020. The balance under the Subordinated Credit Agreement as of October&#160;31, 2021 was $4.3 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On May&#160;9, 2019, in connection with the closing of the purchase of the Bridgeport Fuel Cell Project, BFC &#160;entered into a Credit Agreement with Liberty Bank, as administrative agent and co-lead arranger, and Fifth Third Bank as co-lead arranger and interest rate swap hedger (the &#8220;BFC Credit Agreement&#8221;), whereby (i)&#160;Fifth Third Bank provided financing in the amount of $12.5 million towards the purchase price for the BFC acquisition; and (ii)&#160;Liberty Bank provided financing in the amount of $12.5 million towards the purchase price for the BFC acquisition. As security for the BFC Credit Agreement, Liberty Bank and Fifth Third Bank were granted a first priority lien in (i)&#160;all assets of BFC, including BFC&#8217;s cash accounts, fuel cells, and all other personal property, as well as third party contracts including the Energy Purchase Agreement between BFC and Connecticut Light and Power Company dated July&#160;10, 2009, as amended; (ii)&#160;certain fuel cell modules that are intended to be used to replace the Bridgeport Fuel Cell Project&#8217;s fuel cell modules as part of routine operation and maintenance; and (iii)&#160;FuelCell Finance&#8217;s (a wholly-owned subsidiary of the Company and the direct parent of BFC) ownership interest in BFC. The maturity date under the BFC Credit Agreement is May&#160;9, 2025.&#160;Monthly principal and interest are to be paid in arrears in an amount sufficient to fully amortize the term loan over a 72-month period. BFC has the right to make additional principal payments or pay the balance due under the BFC Credit Agreement in full, provided that it pays any associated breakage fees with regard to the interest rate swap agreements fixing the interest rate. The interest rate under the BFC Credit Agreement fluctuates&#160;monthly at the 30-day LIBOR rate plus 275 basis points.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">An interest rate swap agreement was required to be entered into with Fifth Third Bank in connection with the BFC Credit Agreement to protect against movements in the floating LIBOR index. Accordingly, on May&#160;16, 2019, an interest rate swap agreement (the &#8220;Swap Agreement&#8221;) was entered into with Fifth Third Bank in connection with the BFC Credit Agreement for the term of the loan. The net interest rate across the BFC Credit Agreement and the swap transaction results in a fixed rate of 5.09%. The interest rate swap is adjusted to fair value on a quarterly basis. The estimated fair value is based on Level 2 inputs including primarily the forward LIBOR curve available to swap dealers. The valuation methodology involves comparison of (i)&#160;the sum of the present value of all&#160;monthly variable rate payments based on a reset rate using the forward LIBOR curve and (ii)&#160;the sum of the present value of all&#160;monthly fixed rate payments on the notional amount, which is equivalent to the outstanding principal amount of the loans. The fair value adjustments for the&#160;years ended October&#160;31, 2021, 2020 and 2019 resulted in a $0.5 million gain, a $0.3 million gain and a $0.6 million charge, respectively. The fair value of the interest rate swap liability as of October&#160;31, 2021 and 2020 was $0.5 million and $0.9 million, respectively.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The BFC Credit Agreement requires BFC to maintain a debt service reserve. Each of Liberty Bank and Fifth Third Bank also has an operation and module replacement reserve (&#8220;O&amp;M Reserve&#8221;) under the BFC Credit Agreement. BFC is required to deposit $0.1 million per&#160;month into each O&amp;M Reserve for the first five&#160;years of the BFC Credit Agreement, with such funds to be released at the sole discretion of Liberty Bank and Fifth Third Bank, as applicable. BFC is also required to maintain excess cash flow reserve accounts at each of Liberty Bank and Fifth Third Bank. Excess cash flow consists of cash generated by BFC from the Bridgeport Fuel Cell Project after payment of all expenses (including after payment of intercompany service fees to the Company), debt service to Liberty Bank and Fifth Third Bank, the funding of all required reserves, and payments to Connecticut Green Bank for the subordinated facility. BFC is also required to maintain a debt service coverage ratio of not less than 1.20, measured for the trailing&#160;year based on fiscal quarters beginning with the quarter ended July&#160;31, 2020. The Company has certain quarterly and annual financial reporting requirements under the BFC Credit Agreement. The annual financial statements to be provided pursuant to such requirements are to be audited and accompanied by a report of an independent certified public accountant, which report shall not include a &#8220;going concern&#8221; matter of emphasis or any qualification as to the scope of such audit.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Finance obligations for sale leaseback agreements</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Several of the Company&#8217;s project subsidiaries previously entered into sale-leaseback agreements with PNC for commissioned projects where the Company had entered into a PPA with the site host/end-user of produced power, and CCFC2 and SBFC entered into sale-leaseback transactions with Crestmark on February&#160;11, 2020 and August 25, 2021, respectively (refer to Note. 13. &#8220;Leases&#8221; for additional information). The Company did not recognize as revenue any of the proceeds received from the lessor that contractually constitute payments to acquire the assets subject to these arrangements. Instead, the sale proceeds received were accounted for as financing obligations. The outstanding financing obligation balance as of October&#160;31, 2021 was $56.5 million as compared to $49.3 million as of October&#160;31, 2020. This change reflects the recording of the finance obligation with Crestmark for the San Bernardino Plant sale leaseback transaction and the recognition of interest expense, offset by lease payments. The outstanding financing obligation for the remaining leases includes $34.8 million in excess of future required payments, not including amounts for the potential repurchase price of the project assets which is based on fair value. The sale-leaseback arrangements with PNC allow the </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Company to repurchase the project assets at fair market value and the sale-leaseback arrangements with Crestmark include a purchase right for the greater of fair market value or 31% of the purchase price.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">State of Connecticut Loan</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In October&#160;2015, the Company closed on a definitive Assistance Agreement with the State of Connecticut (the &#8220;Assistance Agreement&#8221;) and received a disbursement of $10.0 million, which was used for the first phase of the expansion of the Company&#8217;s Torrington, Connecticut manufacturing facility. In conjunction with this financing, the Company entered into a $10.0 million promissory note and related security agreements securing the loan with equipment liens and a mortgage on its Danbury, Connecticut location. Interest accrues at a fixed interest rate of 2.0%, and the loan is repayable over 15 years from the date of the first advance, which occurred in October&#160;of 2015. Principal payments were deferred for four years from disbursement and began on December&#160;1, 2019. Under the Assistance Agreement, the Company was eligible for up to $5.0 million in loan forgiveness if the Company created 165 full-time positions and retained 538 full-time positions for two consecutive&#160;years (the &#8220;Employment Obligation&#8221;) as measured on October&#160;28, 2017 (the &#8220;Target Date&#8221;). The Assistance Agreement was subsequently amended in April&#160;2017 to extend the Target Date by two&#160;years to October&#160;28, 2019.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In January&#160;2019, the Company and the State of Connecticut entered into a Second Amendment to the Assistance Agreement (the &#8220;Second Amendment&#8221;). The Second Amendment extended the Target Date to October&#160;31, 2022 and amended the Employment Obligation to require the Company to continuously maintain a minimum of 538 full-time positions for 24 consecutive&#160;months. If the Company meets the Employment Obligation, as modified by the Second Amendment, and creates an additional 91 full-time positions, the Company may receive a credit in the amount of $2.0 million to be applied against the outstanding balance of the loan. However, based on the Company&#8217;s current headcount and plans for fiscal&#160;year 2022 and beyond, it will not meet this requirement or receive this credit. A job audit will be performed within 90 days of the Target Date. If the Company does not meet the Employment Obligation, then an accelerated payment penalty will be assessed at a rate of $18,587.36 multiplied by the number of employees below the number of employees required by the Employment Obligation. Such penalty is immediately payable and will be applied first to accelerate the payment of any outstanding fees or interest due and then to accelerate the payment of outstanding principal.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In April&#160;of 2020, as a result of the COVID-19 pandemic, the State of Connecticut agreed to defer three months of principal and interest payments under the Assistance Agreement, beginning with the May&#160;2020 payment. These deferred payments will be added at the end of the loan, thus extending out the maturity date by three&#160;months.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Liberty Bank Promissory Note</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On April&#160;20, 2020, the Company entered into <span style="background:#ffffff;">a Paycheck Protection Program Promissory Note, dated April 16, 2020 (the &#8220;PPP Note&#8221;)</span>, evidencing a loan to the Company from Liberty Bank, under the CARES Act, administered by the Small Business Administration (&#8220;SBA&#8221;). Pursuant to the PPP Note, the Company received total proceeds of approximately $6.5 million on April&#160;24, 2020 (the &#8220;PPP Loan&#8221;).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;padding-bottom:12pt;text-align:justify;margin:0pt;">The PPP Note&#160;was scheduled to mature on April&#160;16, 2022, had a 1.00% per annum interest rate, and was subject to the terms and conditions applicable to loans administered by the SBA under the CARES Act, as amended by the Paycheck Protection Program Flexibility Act of 2020.&#160;Monthly principal and interest payments, less the amount of any potential forgiveness, commenced on November&#160;16, 2020. The Company did not provide any collateral or guarantees for the PPP Note, nor did the Company pay any facility charge to obtain the PPP Note. The PPP Note&#160;could be prepaid at any time with no prepayment penalties.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;">As required by the Orion Agent and its affiliated lenders (collectively, &#8220;Orion&#8221;) under the Company&#8217;s (now former) senior secured credit facility, the Company applied for forgiveness of the PPP Loan in October 2020.&#160;However, with the repayment in full of all amounts owed to Orion in December 2020, the Company was no longer required to pursue forgiveness of the PPP Loan. Additionally, since the time of the application for forgiveness, the Company&#8217;s financial circumstances changed substantially, such that the Company was no longer in need of forgiveness of the PPP Loan. Accordingly, on February 11, 2021, the Company withdrew its application for forgiveness and repaid all amounts outstanding under the PPP Note, which totaled approximately $6.6 million, and included approximately $0.1 million in interest.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Deferred Finance Costs</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">As of October&#160;31, 2021, deferred finance costs relate primarily to sale-leaseback transactions entered into with PNC and Crestmark, which are being amortized over the <span style="-sec-ix-hidden:Hidden_27VwFBDG_kmIUDv91BPlIg;"><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">10-year</span></span> terms of the lease agreements and payments under the loans obtained to purchase the membership interests in BFC, which are being amortized over the <span style="-sec-ix-hidden:Hidden_UKVkq-mVokK9nDWMnOie7w;"><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">8-year</span></span> term of the loans.</p><span></span>

From the date of this Open Market Sale Agreement through October&#160;31, 2020, 28.3 million shares were sold under this Open Market Sale Agreement at an average sales price of $2.55 per share, resulting in gross proceeds of $72.3 million, before deducting expenses and sales commissions.

The Company accounted for the Second Funding Warrants under ASC 815, <i style="font-style:italic;">Derivatives and Hedging </i>(&#8220;ASC 815&#8221;) since the Second Funding Warrants were considered contingent vesting warrants and therefore were considered to be an outstanding liability. Since the probability of vesting for the Second Funding Warrants was deemed to be 100% as there was no vesting period in the warrants, there was no impact on the valuation. The Second Funding Warrants were accounted for as a liability since the Company might have been required to pay the holder under the same change of control provision as the Initial Funding Warrants and such event was outside the Company&#8217;s control and therefore equity classification was precluded.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">As of October&#160;31, 2019, the estimated fair value of the Orion Warrants was based on a Black-Scholes model using Level 2 inputs, including volatility of 96%, a risk free rate of 1.63%, the Company&#8217;s common stock price as of October&#160;31, 2019 of $0.24 per share and the term of 8 years which resulted in a total value of $3.9 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.09;text-align:justify;margin:10pt 0pt 0pt 0pt;">During the three&#160;months ended January&#160;31, 2020, the lenders exercised, on a cashless basis, Orion Warrants representing the right to purchase 12,000,000 shares of the Company&#8217;s common stock. Because these Orion Warrants were exercised on a cashless basis, the Company issued in the aggregate 9,396,320 shares of the Company&#8217;s common stock.

Redeemable Preferred Stock</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Company is authorized to issue up to 250,000 shares of preferred stock, par value $0.01 per share, in one or more series, of which 105,875 shares were designated as 5% Series&#160;B Cumulative Convertible Perpetual Preferred Stock (referred to herein as Series&#160;B Preferred Stock) in March&#160;2005. Pursuant to our Certificate of Incorporation, as amended, our undesignated shares of preferred stock now include all of our shares of preferred stock that were previously designated as Series&#160;C Convertible Preferred Stock (&#8220;Series C Preferred Stock&#8221;) and Series&#160;D Convertible Preferred Stock (&#8220;Series D Preferred Stock&#8221;), as all such shares have been retired and therefore have the status of authorized and unissued shares of preferred stock undesignated as to series. In addition to the above, a subsidiary of the Company had authorized and issued preferred stock as of October&#160;31, 2021, as described below.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Series&#160;D Preferred Stock</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In August&#160;2018, the Company issued 30,680 shares of Series&#160;D Preferred Stock, which were initially convertible into 1,852,657 shares of the Company&#8217;s common stock at an initial conversion price of $16.56 per share (&#8220;Series&#160;D Conversion Price&#8221;), subject to certain adjustments.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The net proceeds to the Company from the sale of the Series&#160;D Preferred Stock, after deducting the underwriting discounts and commissions and the offering expenses payable by the Company, were $25.3 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">During the fiscal&#160;year ended October&#160;31, 2019, holders of the Series&#160;D Preferred Stock converted all 30,680 shares of Series&#160;D Preferred Stock (the &#8220;Series&#160;D Preferred Shares&#8221;) into 62,040,496 shares of common stock, resulting in a reduction of $31.2 million to the carrying value being recorded to equity. Conversions in which the conversion price was below the fixed conversion price (the initial conversion price of the Series&#160;D Preferred Stock) resulted in a variable number of shares being issued to settle the conversion amounts and were treated as a partial redemption of the Series&#160;D Preferred Shares. Conversions during the&#160;year ended October&#160;31, 2019 that were settled in a variable number of shares and treated as redemptions resulted in deemed dividends of $6.0 million. The deemed dividends represent the difference between the fair value of the shares of common stock issued to settle the conversion amounts and the carrying value of the Series&#160;D Preferred Shares.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Series&#160;D Preferred Stock redemption accretion of $3.8 million for the fiscal&#160;year ended October&#160;31, 2019 reflects the accretion of the difference between the carrying value and the amount that would have been redeemed if stockholder approval had not been obtained for the issuance of common stock equal to 20.0% or more of the Company&#8217;s outstanding voting stock prior to the issuance of the Series&#160;D Preferred Stock. Prior to receiving stockholder approval of the issuance of 20.0% or more of the Company&#8217;s outstanding voting stock prior to the issuance of the Series&#160;D Preferred Stock, the holders were prohibited from converting Series&#160;D Preferred Shares into shares of common stock if such conversion would have caused the Company to issue pursuant to the terms of the Series&#160;D Preferred Stock a number of shares in excess of the maximum number of shares permitted to be issued thereunder without breaching the Company&#8217;s obligations under the rules&#160;or regulations of the Nasdaq Global Market. The Company received stockholder approval of such issuance at the annual meeting of the Company&#8217;s stockholders on April&#160;4, 2019.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">During the week of June&#160;10, 2019, the holders of the Series&#160;D Preferred Stock asserted that certain triggering events had occurred under the Certificate of Designations, Preferences and Rights of the Series&#160;D Preferred Stock of the Company (the &#8220;Series&#160;D Certificate of Designation&#8221;) and indicated their intent to exercise their rights to convert certain of their shares at a reduced conversion price. While the Company did not agree with the basis for their assertions or their characterization of such events, there were provisions under the Series&#160;D Certificate of Designation which could be interpreted as giving the holders the right to demand such conversion at a reduced conversion price. Accordingly, during the period beginning on June&#160;11, 2019 and ending on July&#160;3, 2019, the Company effected conversions at reduced conversion prices ranging from $0.14 to $0.61.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Series&#160;C Preferred Stock</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">During the fiscal&#160;year ended October&#160;31, 2017, the Company issued 33,500 shares of Series&#160;C Preferred Stock (the &#8220;Series C Preferred Shares&#8221;) for net proceeds of $27.9 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">As of October&#160;31, 2018, there were 8,992 shares of Series&#160;C Preferred Stock issued and <span style="-sec-ix-hidden:Hidden_LOfb7tf2i0yNkywastuWtA;"><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">outstanding</span></span>, with a carrying value of $7.5 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On February&#160;21, 2019, the Company entered into a Waiver Agreement (the &#8220;Waiver Agreement&#8221;) with the holder of the Series&#160;C Preferred Stock (such holder, the &#8220;Series&#160;C Holder&#8221;). Under the Waiver Agreement, the Series&#160;C Holder waived any equity conditions failures that may have occurred under the Certificate of Designations, Preferences and Rights of the Series&#160;C Preferred Stock of the Company (the &#8220;Series&#160;C Certificate of Designations&#8221;). The Series&#160;C Holder further waived any triggering event occurring after the date of the Waiver Agreement, as well as its right to demand, require or otherwise receive cash payments under the Series&#160;C Certificate of Designations, which waiver would have terminated upon the occurrence of certain key triggering events (failure to provide freely tradable shares, suspension from trading on the Nasdaq Global Market or another eligible market, or failure to convert or deliver shares under certain circumstances), the occurrence of a fundamental transaction, a breach of the Waiver Agreement, or the occurrence of a bankruptcy triggering event. In addition, the Company agreed in the Waiver Agreement, pursuant to Section&#160;8(d)&#160;of the Series&#160;C Certificate of Designations, to adjust the conversion price of the Series&#160;C Preferred Stock in connection with future conversions, such that, when the Series&#160;C Holder converted its Series&#160;C Preferred Stock into common stock, it would receive approximately 25% more shares than it would have received upon conversion prior to the execution of the Waiver Agreement. Under the Waiver Agreement, the conversion price of the Series&#160;C Preferred Stock was stated to be the lowest of (i)&#160;$4.45, (ii)&#160;85% of the lowest closing bid price of the Company&#8217;s common stock during the period beginning on and including the fifth trading day prior to the date on which the applicable conversion notice was delivered to the Company and ending on and including the date on which the applicable conversion notice was delivered to the Company, and (iii)&#160;85% of the quotient of (A)&#160;the sum of the five lowest volume weighted average prices of the Company&#8217;s common stock during the 20 consecutive trading day period ending on and including the trading day immediately preceding the applicable conversion date divided by (B)&#160;five. To determine the number of shares of common stock to be issued upon conversion, 125% of the value of the Series&#160;C Preferred Shares being converted was divided by the applicable conversion price. The parties further agreed to waive the installment payment/conversion provisions in Section&#160;9 of the Series&#160;C Certificate of Designations, which required installment conversions or payments to be made on the 1<sup style="font-size:7.5pt;line-height:100%;top:0pt;vertical-align:top;">st</sup> and 16<sup style="font-size:7.5pt;line-height:100%;top:0pt;vertical-align:top;">th</sup> of each&#160;month. Under the Waiver Agreement, conversions of Series&#160;C Preferred Stock were permitted to occur and did occur after the original March&#160;1, 2019 maturity date, and the Company further agreed to reserve specific numbers of shares for issuance to the Series&#160;C Holder and the holders of the Series&#160;D Preferred Stock until the Company effected a reverse stock split, which occurred on May&#160;8, 2019, or increased its authorized shares of common stock.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Waiver Agreement was treated for accounting purposes to be an extinguishment of the Series&#160;C Preferred Stock instrument as of February&#160;21, 2019. The Series&#160;C Preferred Stock remained classified in mezzanine equity, however, the carrying value was adjusted to reflect the estimated fair value of the post-modification Series&#160;C Preferred Shares which incorporated the new terms outlined in the Waiver Agreement. The valuation utilized a Binomial Lattice Model (&#8220;Lattice Model&#8221;) which is a commonly used methodology to value path-dependent options or stock units in order to capture their potential early conversion. The Lattice Model produces an estimated fair value based on changes in the underlying stock price over successive periods of time. The assumptions used in the model such as stock price, conversion price and conversion ratio were consistent with date of execution and terms in the Waiver Agreement. Other assumptions included the volatility of the Company&#8217;s stock which was assumed to be 75% and a discount rate of 20% which was estimated based on various indices consistent with the Company&#8217;s profile, venture capital rates of return and the Company&#8217;s borrowing rate. The Lattice Model resulted in an estimated fair value as of February&#160;21, 2019 of $13.5 million whereby the Series&#160;C Preferred Stock carrying value was adjusted to this amount. As discussed below, a beneficial conversion feature was recorded during the three&#160;months ended January&#160;31, 2019 due to reductions in the conversion price. Upon extinguishment during the three&#160;months ended April&#160;30, 2019, the Company first allocated $6.6 million to the reacquisition of the embedded conversion option equal to the intrinsic value that was previously recognized during the three&#160;months ended January&#160;31, 2019 for the embedded conversion option. Because the remaining estimated fair value of the instrument on February&#160;21, 2019 was less than the carrying amount of the Series&#160;C Preferred Stock, the amount of the shortfall resulted in a decrease in loss available to common stockholders for purposes of computing loss per share of $0.6 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In order to resolve different interpretations of the provisions of the Series&#160;C Certificate of Designations that governed adjustments to the conversion price in connection with sales of common stock under the Company&#8217;s at-the-market stock sales plan below the initial conversion price of $22.08 and whether such sales constituted sales of variable priced securities under the Series&#160;C Certificate of Designations, the Company&#8217;s Board of Directors agreed to reduce the conversion price of the Series&#160;C Preferred Shares from $22.08 to $18.00 effective August&#160;27, 2018 in exchange for a waiver of certain anti-dilution and price adjustment rights under the Series&#160;C Certificate of Designations for future at-the-market sales of common stock. The conversion price of the Series&#160;C Preferred Shares was adjusted again on December&#160;3, 2018 to $6.96, on December&#160;17, 2018 to $6.00 and on January&#160;2, 2019 to $5.16. During the period from February&#160;1, 2019 to May&#160;23, 2019, the conversion price was further adjusted to prices ranging from $4.45 to $1.27, the conversion price as of the last conversion, which occurred on May&#160;23, 2019. Conversions occurring during the fiscal&#160;year ended October&#160;31, 2019 resulted in a variable number of shares being issued to settle the conversion amounts and were treated as a partial redemption of the Series&#160;C Preferred Shares. Conversions during the&#160;year ended October&#160;31, 2019 that were settled in a variable number of shares and treated as partial redemptions resulted in deemed contributions of $1.5 million. The deemed contributions represent the difference between the fair value of the common shares issued to settle the conversion amounts and the carrying value of the Series&#160;C Preferred Shares. Additionally, as discussed in more detail above, the net loss attributable to common stockholders for the fiscal&#160;year ended October&#160;31, 2019 was impacted by a $0.5 million decrease in the loss resulting from accounting for the Waiver Agreement in February&#160;2019, which was recorded during the three&#160;months ended April&#160;30, 2019. The net loss attributable to common stockholders for the&#160;year ended October&#160;31, 2019 also includes the $8.6 million redemption value adjustment recorded during the three&#160;months ended January&#160;31, 2019.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Series&#160;C Preferred Shares were classified outside of permanent equity. The decline in the Company&#8217;s stock price during the three&#160;months ended January&#160;31, 2019 and between January&#160;31, 2019 and the execution of the Waiver Agreement in February&#160;2019 resulted in equity conditions failures under the Series&#160;C Certificate of Designations, which were waived by the Series&#160;C Holder in the Waiver Agreement, as described above. Prior to the execution of such Waiver Agreement, the conversion price was adjusted in December&#160;2018 and January&#160;2019 as described above. This contingent beneficial conversion feature resulted in a $6.6 million reduction in the Series&#160;C Preferred Shares carrying value. Because the equity conditions failures were continuing as of January&#160;31, 2019 (prior to the execution of the Waiver Agreement), the Series&#160;C Preferred Shares were adjusted to 108% of stated redemption value as of January&#160;31, 2019 with a corresponding charge to common stockholders of $8.6 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">During the fiscal&#160;year ended October&#160;31, 2019, holders of the Series&#160;C Preferred Stock converted 8,992 Series&#160;C Preferred Shares into 3,914,218 shares of common stock, resulting in a reduction in carrying value of $15.5 million. Upon the conversion of the last outstanding Series&#160;C Preferred Shares on May&#160;23, 2019, there were no further Series&#160;C Preferred Shares outstanding.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">During the fiscal&#160;year ended October&#160;31, 2018, holders of the Series&#160;C Preferred Stock converted 24,308 Series&#160;C Preferred Shares into common shares through installment conversions resulting in a reduction of $20.2 million to the carrying value being recorded to equity. Installment conversions occurring prior to August&#160;27, 2018 in which the conversion price was </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">below the initial conversion price of $22.08 per share resulted in a variable number of shares being issued to settle the installment amount and were treated as a partial redemption of the Series&#160;C Preferred Shares. As discussed above, the Company&#8217;s Board of Directors agreed to reduce the conversion price of the Series&#160;C Preferred Shares from $22.08 to $18.00 effective August&#160;27, 2018 in exchange for a waiver of certain anti-dilution and price adjustment rights under the Series&#160;C Certificate of Designations for future at-the-market sales. Installment conversions occurring between August&#160;27, 2018 and October&#160;31, 2018 in which the installment conversion price was below the adjusted conversion price of $18.00 per share resulted in a variable number of shares being issued to settle the installment amount and were treated as a partial redemption of the Series&#160;C Preferred Shares. Installment conversions during the&#160;year ended October&#160;31, 2018 that were settled in a variable number of shares and treated as partial redemptions resulted in deemed dividends of $9.6 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Redeemable Series&#160;B Preferred Stock</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Company has designated 105,875 shares of its authorized preferred stock as Series&#160;B Preferred Stock (liquidation preference $1,000.00 per share). As of October&#160;31, 2021 and 2020, there were 64,020 shares of Series&#160;B Preferred Stock issued and outstanding, with a carrying value of $59.9 million.

The dividend rate is also subject to upward adjustment as set forth in the Registration Rights Agreement entered into with the initial purchasers of the Series&#160;B Preferred Stock (the &#8220;Registration Rights Agreement&#8221;) if the Company fails to satisfy its registration obligations with respect to the Series&#160;B Preferred Stock (or the underlying shares of common stock) under the Registration Rights Agreement.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">No dividends or other distributions may be paid or set apart for payment on the Company&#8217;s common stock (other than a dividend payable solely in shares of a like or junior ranking), nor may any stock junior to or on parity with the Series&#160;B Preferred Stock be redeemed, purchased or otherwise acquired for any consideration (or any money paid to or made available for a sinking fund for such stock) by the Company or on its behalf&#8201; (except by conversion into or exchange for shares of a like or junior ranking), unless all accumulated and unpaid dividends on the Series&#160;B Preferred Stock have been paid or funds or shares of common stock have been set aside for payment of such accumulated and unpaid dividends.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The dividend on the Series&#160;B Preferred Stock may be paid in cash or, at the option of the holder, in shares of the Company&#8217;s common stock.

Based on the dividend rate in effect on May&#160;15, 2019 and August&#160;15, 2019, the aggregate amount of such dividend payments would have been $1.6 million. Because such dividends were not paid on May&#160;15 or August&#160;15, under the terms of the Series&#160;B Certificate of Designation, the holders of shares of Series&#160;B Preferred Stock were entitled to receive, when, as and if, declared by the Board of Directors, dividends at a dividend rate per annum equal to the normal dividend rate of 5% plus an amount equal to the number of dividend periods for which the Company </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">failed to pay or set apart funds to pay dividends multiplied by 0.0625%, for each subsequent dividend period until the Company has paid or provided for the payment of all dividends on the shares of Series&#160;B Preferred Stock for all prior dividend periods.&#160;On October&#160;30, 2019, dividends were declared by the Board of Directors with respect to the May&#160;15, 2019 and August&#160;15, 2019 dividend payment dates as well as the November&#160;15, 2019 dividend payment date. A payment of $2.4 million made in the fiscal quarter ended January&#160;31, 2020 represented the dividends payable with respect to the May&#160;15, 2019 and August&#160;15, 2019 dividend dates and the dividends payable with respect to the November&#160;15, 2019 dividend date that were declared on October&#160;30, 2019.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"><b style="font-weight:bold;">Liquidation.</b> The holders of Series&#160;B Preferred Stock are entitled to receive, in the event that the Company is liquidated, dissolved or wound up, whether voluntarily or involuntarily, $1,000.00 per share plus all accumulated and unpaid dividends up to but excluding the date of such liquidation, dissolution, or winding up (the &#8220;Liquidation Preference&#8221;).

The conversion rate is subject to adjustment upon the occurrence of certain events, as described in the Series&#160;B Certificate of Designation. The conversion rate is not adjusted for accumulated and unpaid dividends. If converted, holders of Series&#160;B Preferred Stock do not receive a cash payment for all accumulated and unpaid dividends; rather, all accumulated and unpaid dividends are canceled.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Company may, at its option, cause shares of Series&#160;B Preferred Stock to be automatically converted into that number of shares of its common stock that are issuable at the then-prevailing conversion rate.

Subsequent to the end of fiscal&#160;year 2020, the Company paid off these obligations to Enbridge. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On January&#160;20, 2020, the Company, FCE&#160;Ltd. and Enbridge entered into a letter agreement (the &#8220;January&#160;2020 Letter Agreement&#8221;), pursuant to which they agreed to amend the articles of FCE&#160;Ltd. relating to and setting forth the terms of the Series&#160;1 Preferred Shares to: (i)&#160;remove the provisions of the articles permitting or requiring the issuance of shares of the Company&#8217;s common stock in exchange for the Series&#160;1 Preferred Shares or as payment of amounts due to the holders of the Series&#160;1 Preferred Shares, (ii)&#160;remove certain provisions of the articles relating to the redemption of the Series&#160;1 Preferred Shares, (iii)&#160;increase the annual dividend rate, commencing on January&#160;1, 2020, to 15%, (iv)&#160;extend the final payment date for all accrued and unpaid dividends and all return of capital payments (i.e., payments of the principal redemption price) from December&#160;31, 2020 to December&#160;31, 2021, (v)&#160;clarify when dividend and return of capital payments were to be made in the future and extend the quarterly dividend and return of capital payments through December&#160;31, 2021 (which were previously to be paid each quarter through December&#160;31, 2020), (vi)&#160;remove certain terms and provisions of the articles that are no longer applicable, and (vii)&#160;make other conforming changes to the articles. The articles of FCE&#160;Ltd. were amended and filed in accordance with the provisions of the January&#160;2020 Letter Agreement on March&#160;26, 2020. Under the amended articles, FCE&#160;Ltd. continued to be required to make (a)&#160;annual dividend payments of Cdn. $500,000&#160;and (b)&#160;annual return of capital payments of Cdn. $750,000.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The amendment to the Series&#160;1 Preferred Shares resulted in an extinguishment of the prior Series&#160;1 Preferred Shares for accounting purposes. A revised fair value was estimated using a discounted cash flow model resulting in a revised carrying value being recorded for the amended Series&#160;1 Preferred Shares of Cdn. $23.4 million (U.S. $17.7 million) as of January&#160;20, 2020, which resulted in a loss of Cdn. $0.2 million (U.S. $0.2 million) recorded in Other income, net on the Consolidated Statements of Operations and Comprehensive Loss during the&#160;year ended October&#160;31, 2020. On an undiscounted basis, the Company&#8217;s actual aggregate amount of all accrued and unpaid dividends to be paid on the Series&#160;1 Preferred Shares as of October&#160;31, 2020 totaled approximately Cdn. $23.2 million (U.S. $17.4 million) and the balance of the principal redemption price as of October&#160;31, 2020 with respect to all of the Series&#160;1 Preferred Shares totaled approximately Cdn. $4.3 million (U.S. $3.2 million).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Prior to the amendment, the Company bifurcated embedded derivatives related to the conversion feature and a variable dividend feature. As a result of the January&#160;2020 Letter Agreement, both features were removed from the Series&#160;1 Preferred Shares which resulted in the Company recognizing a gain of $0.6 million related to the extinguishment of the embedded derivatives.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The following summary of the terms of the Series&#160;1 Preferred Shares describes such terms as they existed on October&#160;31, 2019 (prior to any modification covered by the January&#160;2020 Letter Agreement and the resulting amendment of the articles of FCE&#160;Ltd.). The terms of the Series&#160;1 Preferred Shares required (i)&#160;annual dividend payments of Cdn. $500,000 and (ii)&#160;annual return of capital payments of Cdn. $750,000. Dividends accrued at a 1.25% quarterly rate on the unpaid principal balance, and additional dividends accrued on the cumulative unpaid dividends (inclusive of the Cdn. $12.5 million unpaid dividend balance as of the modification date) at a rate of 1.25% compounded quarterly. FCE&#160;Ltd. had the option, subject to the Company having sufficient authorized and unissued shares, of making dividend payments in the form of cash or shares of the Company&#8217;s common stock under the terms of the Series&#160;1 Preferred Shares.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Because the Series&#160;1 Preferred Shares represented a mandatorily redeemable financial instrument, they were presented as a liability on the Consolidated Balance Sheets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Company made payments of Cdn. $1.9 million (or USD $1.6 million) and Cdn. $0.3 million (or USD $0.2 million) during fiscal&#160;years 2020 and 2019, respectively. The Company&#8217;s return of capital and dividend payments were not made for the calendar quarters ended on March&#160;31, 2019, June&#160;30, 2019 and September&#160;30, 2019. During fiscal&#160;year 2020, the Company made the return of capital and dividend payments for the obligations due as of March&#160;31, 2019, June&#160;30, 2019 and September&#160;30, 2019. The Company recorded interest expense, which reflects the amortization of the fair value discount of approximately Cdn. $4.0 million (or USD $2.9 million) and Cdn. $3.0 million (or USD $2.3 million) in the fiscal&#160;years ended October&#160;31, 2020 and 2019, respectively. As of October&#160;31, 2020, the carrying value of the Series&#160;1 Preferred Shares was Cdn. $25.6 million ($19.2 million) and was classified as preferred stock obligation of subsidiary on the Consolidated Balance Sheets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In December&#160;2020, the Company, FCE&#160;Ltd., and Enbridge entered into a payoff letter, pursuant to which the Company paid all amounts owed to Enbridge under the terms of the Series&#160;1 Preferred Shares. As of the date of the payoff letter, the amount owed to Enbridge under the Series&#160;1 Preferred Shares totaled Cdn. $27.4 million, which included Cdn. $4.3 million of principal and Cdn. $23.1 million of accrued dividends.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On December&#160;18, 2020, the Company remitted payment totaling&#160;Cdn. $27.4 million, or approximately U.S. $21.5 million, to Enbridge. Upon making the payment, the Company recorded a loss on extinguishment for the Series&#160;1 Preferred Shares of $0.9 million. Concurrent with receipt of the payment from the Company, Enbridge surrendered its Series&#160;1 Preferred Shares in FCE&#160;Ltd., and the Guarantee and the January&#160;2020 Letter Agreement were terminated. All obligations related to the Series&#160;1 Preferred Shares were extinguished upon payment.</p><span></span>

Critical to the success of our business is, among other things, our research and development efforts, both through customer-sponsored projects and Company-sponsored projects. The research and development activities are viewed as another product line that contributes to the development, design, production and sale of fuel cell products, however, it is not considered a separate operating segment. The chief operating decision maker does not review and assess financial information at a discrete enough level to be able to assess performance of research and development activities as if they operated as a standalone business segment, therefore, the Company has identified one business segment: fuel cell power plant production and research.</p><p style="font-family:'Times New

Award to Jason Few, the Company&#8217;s President and Chief Executive Officer (the &#8220;CEO&#8221;), pursuant to the August&#160;26, 2019 employment agreement between the Company and the CEO. Pursuant to the terms of such Sign-On Award, 500,000 RSUs vest on August&#160;26, 2022. The remaining 500,000 RSUs (&#8220;Additional RSUs&#8221;) will vest if, during the 30 days prior to the vesting date of August 26, 2022, the weighted average price of the Company&#8217;s common stock exceeds $1.00. The number of Additional RSUs will range from zero for a weighted average price of $1.00 to a maximum of 500,000 RSUs for a weighted average price of $6.00, with linear interpolation for stock prices between $1.00 and $6.00. The vesting of all RSUs is subject to the individual&#8217;s continuous employment with the Company through the vesting date. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The outstanding restricted stock awards and units also include awards made on August&#160;24, 2020, under the FY 2020 LTI Plan, totaling 835,038 RSUs which include 668,030 performance awards and 167,008 time-based awards. Performance awards were issued assuming participants achieve 100% target performance. Should participants achieve the 200% performance level, they will receive up to 545,209 additional RSUs. The performance awards were valued based upon a Monte Carlo Simulation, and the 334,015 relative TSR performance shares were valued at $4.62 per share and the 334,015 absolute performance shares were valued at $5.17 per share. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On November&#160;24, 2020, 848,078 RSUs were awarded under the FY 2021 LTI Plan, which include 551,252 performance units and 296,826 time-based units. Should the Company&#8217;s share price achieve the 200% performance level, awardees will receive up to 446,158 additional RSUs. The performance units were valued based on a Monte-Carlo Simulation, and the estimated fair value of the 275,626 relative TSR performance units was $14.41 per share and the estimated fair value of the 275,626 absolute TSR performance units was $15.36 per share.

The adoption of the ESPP allows the Company to provide eligible employees of FuelCell Energy,&#160;Inc. and certain of its designated subsidiaries with the opportunity to voluntarily participate in the ESPP, enabling such participants to purchase shares of the Company&#8217;s common stock at a discount to market price at the time of such </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">purchase.

Shares issued pursuant to the ESPP contain a legend restricting the transfer or sale of such common stock for a period of 0.5 year after the date of purchase.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The ESPP activity for the&#160;years ended October&#160;31, 2021, 2020 and 2019 was de minimis.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Employee Tax-Deferred Savings Plans</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">We offer a 401(k)&#160;plan (the &#8220;401(k)&#160;Plan&#8221;) to all full time employees that provides for tax-deferred salary deductions for eligible employees (beginning the first&#160;month following an employee&#8217;s hire date). Employees may choose to make voluntary contributions of their annual compensation to the 401(k)&#160;Plan, limited to an annual maximum amount as set periodically by the IRS. Employee contributions are fully vested when made. Under the 401(k)&#160;Plan, there is no option available to the employee to receive or purchase our common stock. Matching contributions of 2% under the 401(k)&#160;Plan aggregated $0.4 million, $0.3 million and $0.5 million for the&#160;years ended October&#160;31, 2021, 2020, and 2019, respectively.</p><span></span>

Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">We continually evaluate our deferred tax assets as to whether it is &#8220;more likely than not&#8221; that the deferred tax assets will be realized. In assessing the realizability of our deferred tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies. Based on the projections for future taxable income over the periods in which the deferred tax assets are realizable, management believes that significant uncertainty exists surrounding the recoverability of the deferred tax assets. As a result, we recorded a valuation allowance against our net deferred tax assets. As of October&#160;31, 2021, we had $368.7 million of federal net operating loss (&#8220;NOL&#8221;) carryforwards that expire in the&#160;years 2022 to 2038 and $518.6 million of state NOL carryforwards that expire in the&#160;years 2022 through 2041. Additionally, we had $11.7 million of state tax credits available that will expire from tax&#160;years 2022 to 2040. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">During the&#160;2020 tax year, the Company experienced an &#8220;ownership change&#8221; as defined by Internal Revenue Code Section&#160;382. As a result, the utilization of federal and state NOLs generated prior to October&#160;of 2020 is subject to limitation and a reduction was made in fiscal year 2020 to the carrying balance of the federal and state NOLs to reflect the future limitation on utilization. The Company has updated its analysis of potential ownership changes through October 31, 2021 and concluded that no additional ownership changes have occurred subsequent to October 2020. In addition, the acquisition of Versa in fiscal&#160;year 2013 triggered a Section&#160;382 ownership change at the level of Versa Power System which will limit the future usage of some of the federal and state NOLs that we acquired in that transaction. Accordingly, a valuation allowance has been recorded against the deferred tax asset associated with these attributes to reflect the future limitation on utilization.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The Company&#8217;s financial statements reflect expected future tax consequences of uncertain tax positions that the Company has taken or expects to take on a tax return (including a decision whether to file or not file a return in a particular jurisdiction) presuming the taxing authorities&#8217; full knowledge of the position and all relevant facts.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">The liability for unrecognized tax benefits as of October&#160;31, 2021 and 2020 was $0. Due to the Section&#160;382 ownership change that occurred in 2020, the underlying NOLs associated with any historical uncertain tax position, are no longer available for utilization, and therefore a deferred tax asset is not recorded on the Consolidated Balance Sheet and the uncertain tax position was released in 2020. It is our policy to record interest and penalties on unrecognized tax benefits as income taxes; however, because of our significant NOLs, no provision for interest or penalties has been recorded. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">We file income tax returns in the U.S. and certain states, primarily Connecticut and California, as well as income tax returns required internationally for South Korea and Germany. We are open to examination by the IRS and various states in which we file for fiscal&#160;year 2002 to the present. </p><span></span>

Under the terms of such service agreements, the particular power plant must meet a minimum operating output during defined periods of the term. If minimum output falls below the contract requirement, the Company may be subject to performance penalties and/or may be required to repair or replace the customer&#8217;s fuel cell module(s).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Power Purchase Agreements</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Under the terms of the Company&#8217;s PPAs, customers agree to purchase power from the Company&#8217;s fuel cell power plants at negotiated rates. Electricity rates are generally a function of the customers&#8217; current and estimated future electricity pricing available from the grid. As owner or lessee of the power plants, the Company is responsible for all operating costs necessary to maintain, monitor and repair the power plants. Under certain agreements, the Company is also responsible for procuring fuel, generally natural gas or biogas, to run the power plants. In addition, under the terms of some of the PPAs, the Company may be subject to a performance penalty if the Company does not meet certain performance requirements.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-style:italic;font-weight:bold;">Project Fuel Exposure</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Certain of our PPAs for project assets in the Company&#8217;s generation operating portfolio and project assets under construction expose us to fluctuating fuel price risks as well as the risk of being unable to procure the required amounts of fuel and the lack of alternative available fuel sources. The Company seeks to mitigate our fuel risk using strategies including: (i) fuel cost reimbursement mechanisms in our PPAs to allow for pass through of fuel costs (full or partial) where possible which we have done with our 14.9 MW operating project in Bridgeport, CT and our 7.4 MW project under </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">construction in Hartford, CT; (ii) procuring fuel under fixed price physical contracts with investment grade counterparties which we have done for twenty years under our Tulare BioMAT project and the initial seven years of the twenty year PPA for our LIPA Yaphank, NY project; and (iii) entering into financial hedges with investment grade counterparties to offset potential negative market fluctuations.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">The Company currently has three projects in development with fuel sourcing risk, which are the Toyota Project which requires procurement of RNG, and our Derby, CT 14.0 MW and 2.8 MW projects, which require natural gas. Fuel sourcing and risk mitigation strategies for all three projects are being assessed and will be implemented as project operational dates become firm. Such strategies may require cash collateral or reserves to secure fuel or related contracts for these three projects. If the Company is unable to secure fuel on favorable economic terms, it may result in impairment charges to these project assets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Other</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">As of October&#160;31, 2021, the Company had unconditional purchase commitments aggregating $71.1 million, for materials, supplies and services in the normal course of business.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Legal Proceedings</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">POSCO Energy Matters</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">From approximately 2007 through 2015, the Company relied on POSCO Energy Co., Ltd. (&#8220;POSCO Energy&#8221;) to develop and grow the South Korean and Asian markets for our products and services. We received upfront license payments and were entitled to receive royalty income from POSCO Energy pursuant to certain manufacturing and technology transfer agreements, including the Alliance Agreement dated February&#160;7, 2007 (and the amendments thereto), the Technology Transfer, License and Distribution Agreement dated February&#160;7, 2007 (and the amendments thereto), the Stack Technology Transfer and License Agreement dated October&#160;27, 2009 (and the amendments thereto), and the Cell Technology Transfer and License Agreement dated October&#160;31, 2012 (and the amendments thereto), which are collectively referred to herein as the &#8220;License Agreements.&#8221;&#160;The License Agreements provided POSCO Energy with the exclusive technology rights to manufacture, sell, distribute and service our SureSource 300, SureSource 1500, and SureSource 3000 fuel cell technology in the South Korean and broader Asian markets. Due to certain actions and inactions of POSCO Energy, the Company has not realized any new material revenues, royalties or new projects developed by POSCO Energy since late 2015.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In November&#160;2019, POSCO Energy spun-off its fuel cell business into a new entity, Korea Fuel Cell Co.,&#160;Ltd. (&#8220;KFC&#8221;), without the Company&#8217;s consent. As part of the spin-off, POSCO Energy transferred manufacturing and service rights under the License Agreements to KFC, but retained distribution rights and severed its own liability under the License Agreements. The Company formally objected to POSCO Energy&#8217;s spin-off, and POSCO Energy posted a bond to secure any liabilities to the Company arising out of the spin-off. In September&#160;2020, the Korean Electricity Regulatory Committee found that POSCO Energy&#8217;s spin-off of the fuel cell business to KFC may have been done in violation of South Korean law.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On February&#160;19, 2020, the Company notified POSCO Energy in writing that it was in material breach of the License Agreements by (i)&#160;its actions in connection with the spin-off of the fuel cell business to KFC, (ii)&#160;its suspension of performance through its cessation of all sales activities since late 2015 and its abandonment of its fuel cell business in Asia, and (iii)&#160;its disclosure of material nonpublic information to third parties and its public pronouncements about the fuel cell business on television and in print media that have caused reputational damage to the fuel cell business, the Company and its products. The Company also notified POSCO Energy that, under the terms of the License Agreements, it had 60&#160;days to fully cure its breaches to the Company&#8217;s satisfaction and that failure to so cure would lead to termination of the License Agreements. Further, on March&#160;27, 2020, the Company notified POSCO Energy of additional instances of its material breach of the License Agreements based on POSCO Energy&#8217;s failure to pay royalties required to be paid in connection with certain module exchanges.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On April&#160;27, 2020, POSCO Energy initiated a series of three arbitration demands against the Company at the International Court of Arbitration of the International Chamber of Commerce seated in Singapore, in which it alleged certain warranty defects in a sub-megawatt conditioning facility at its facility in Pohang, South Korea and sought combined damages of approximately $3.3 million. Prior to filing the arbitrations, POSCO Energy obtained provisional attachments from the </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Seoul Central District Court attaching certain revenues owed to the Company by Korea Southern Power Company (&#8220;KOSPO&#8221;) as part of such warranty claims, which delayed receipt of certain payments owed to the Company. POSCO Energy subsequently sought additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on unspecified warranty claims in an additional amount of approximately $7 million, and additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on its alleged counterclaims in the license termination arbitration described below in an additional amount of approximately $110 million. As of October&#160;31, 2021, outstanding accounts receivable due from KOSPO were $11.2 million. <span style="background:#ffffff;">POSCO Energy posted a bond in the amount of </span><span style="background:#ffffff;">$46</span><span style="background:#ffffff;">&#160;million to secure any damages to the Company resulting from the attachments.</span><span style="font-size:12pt;"> </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-size:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On June&#160;28, 2020, the Company terminated the License Agreements and filed a demand for arbitration against POSCO Energy and KFC in the International Court of Arbitration of the International Chamber of Commerce based on POSCO Energy&#8217;s (i)&#160;failure to exercise commercially reasonable efforts to sell the Company&#8217;s technology in the South Korean and Asian markets, (ii)&#160;disclosure of the Company&#8217;s proprietary information to third parties, (iii)&#160;attack on the Company&#8217;s stock price and (iv)&#160;spin-off of POSCO Energy&#8217;s fuel cell business into KFC without the Company&#8217;s consent. The Company requested that the arbitral tribunal (a)&#160;confirm through declaration that POSCO Energy&#8217;s exclusive license to market the Company&#8217;s technology and products in South Korea and Asia is null and void as a result of the breaches of the License Agreements and that the Company had the right to pursue direct sales in these markets, (b)&#160;order POSCO Energy and KFC to compensate the Company for losses and damages suffered in the amount of more than $200 million, and (c)&#160;order POSCO Energy and KFC to pay the Company&#8217;s arbitration costs, including counsel fees and expenses. The Company retained outside counsel on a contingency basis to pursue its claims, and outside counsel entered into an agreement with a litigation finance provider to fund the legal fees and expenses of the arbitration. In October&#160;2020, POSCO Energy filed a counterclaim in the arbitration (x)&#160;seeking approximately $880 million in damages based on allegations that the Company misrepresented the capabilities of its fuel cell technology to induce POSCO Energy to enter into the License Agreements and failed to turn over know-how sufficient for POSCO Energy to successfully operate its business; (y)&#160;seeking a declaration that the License Agreements remained in full force and effect and requesting the arbitral tribunal enjoin the Company from interfering in POSCO Energy&#8217;s exclusive rights under the License Agreements and (z)&#160;seeking an order that the Company pay POSCO Energy&#8217;s arbitration costs, including counsel fees and expenses.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In July 2020, the Company discontinued revenue recognition of the deferred license revenue related to the License Agreements given the then pending arbitrations.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On August&#160;28, 2020, POSCO Energy filed a complaint in the Court of Chancery of the State of Delaware (the &#8220;Court&#8221;) purportedly seeking to enforce its rights as a stockholder of the Company to inspect and make copies and extracts of certain books and records of the Company and/or the Company&#8217;s subsidiaries pursuant to Section&#160;220 of the Delaware General Corporation Law and/or Delaware common law. POSCO Energy alleged that it was seeking to inspect these documents for a proper purpose reasonably related to its interests as a stockholder of the Company, including investigating whether the Company&#8217;s Board of Directors and its management breached their fiduciary duties of loyalty, due care, and good faith. POSCO Energy sought an order of the Court permitting POSCO Energy to inspect and copy the demanded books and records, awarding POSCO Energy reasonable costs and expenses, including reasonable attorney&#8217;s fees incurred in connection with the matter, and granting such other and further relief as the Court deemed just and proper. On July 9, 2021, the Court issued a post-trial ruling denying POSCO Energy&#8217;s demand to inspect the Company&#8217;s books and records because POSCO Energy lacked a proper purpose. The Court held that the totality of the circumstances, including the fact that this complaint was the seventh legal action POSCO Energy initiated against the Company within the span of nine months, confirmed that POSCO Energy&#8217;s purpose in initiating the books and records demand and filing the complaint was not proper. As this dispute was resolved by the Court as described above, it did not require resolution pursuant to, and was not part of, the Settlement Agreement described in Note 24. &#8220;Subsequent Events.&#8221;<span style="font-size:12pt;"> </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="font-size:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">On September&#160;14, 2020, POSCO Energy filed a complaint in the United States District Court for the Southern District of New York (the &#8220;SD Court&#8221;) alleging that the Company delayed the removal of restrictive legends on certain share certificates held by POSCO Energy in 2018, thus precluding POSCO Energy from selling the shares and resulting in claimed losses in excess of $1.0 million. On September 16, 2021, the SD Court ruled in the Company&#8217;s favor on a motion for summary judgement dismissing all four counts of POSCO Energy&#8217;s complaint regarding share certificates held by POSCO Energy in 2018, but granted POSCO Energy leave to file an amended complaint.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">In order to resolve the disputes described above (other than the books and records dispute which was resolved by the Court), on December 20, 2021, the Company entered into the Settlement Agreement with POSCO Energy and KFC. For more information on the Settlement Agreement, refer to Note 24. &#8220;Subsequent Events&#8221;.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Other Legal Proceedings</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">From time to time, the Company is involved in other legal proceedings, including, but not limited to, regulatory proceedings, claims, mediations, arbitrations and litigation, arising out of the ordinary course of its business (&#8220;Other Legal Proceedings&#8221;). Although the Company cannot assure the outcome of such Other Legal Proceedings, management presently believes that the result of such Other Legal Proceedings, either individually, or in the aggregate, will not have a material adverse effect on the Company&#8217;s consolidated financial statements, and no material amounts have been accrued in the Company&#8217;s consolidated financial statements with respect to these matters.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Impact of the COVID-19 Pandemic</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">During fiscal&#160;year 2020, the Company launched a proactive response to the escalating COVID-19 outbreak and temporarily suspended operations at its Torrington, Connecticut manufacturing facility in March&#160;2020. The Company also commenced remote work protocol for those employees worldwide that were capable of working from home. The Company took these actions to secure the safety of the Company&#8217;s employees, our corporate community as a whole, and the communities in which our team members live, and to adhere to Centers for Disease Control (CDC) recommendations of social distancing and limited public exposure in connection with the COVID-19 pandemic. All employees that were not able to work from home during the manufacturing facility shutdown due to their job function received full wages and benefits during such time. We did not implement any furlough, layoff or shared work program during such time. The Company resumed manufacturing in June&#160;2020 and the Torrington, Connecticut manufacturing facility employees returned to work. We established a phased-in return to work schedule commencing March&#160;15, 2021 for those employees working from home which was completed in April 2021. We will continue to evaluate our ability to operate in the event of a resurgence of COVID-19 and the advisability of continuing operations based on federal, state and local guidance, evolving data concerning the pandemic and the best interests of our employees, customers and stockholders. In addition, given the continued elevated number of &#160;COVID-19 cases throughout the U.S. as a result of the highly transmissible Delta and Omicron variants, the Company instituted policies to protect its employees and customers &#160;such as a mandatory vaccination policy which required all U.S. employees to be fully vaccinated by November 1, 2021 or seek a qualified religious and/or medical exemption with weekly testing protocols.</p><span></span>

Franklin Park&#8217;s tax equity commitment totals $12.4 million.&#160;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">This transaction was structured as a &#8220;partnership flip,&#8221; which is a structure commonly used by tax equity investors in the financing of renewable energy projects. Under this partnership flip structure, a partnership, in this case YTBFC Holdco, LLC (the &#8220;Yaphank Partnership&#8221;), was organized to acquire from FuelCell Energy Finance II, LLC, a wholly-owned subsidiary of the Company, all outstanding equity interests in Yaphank Fuel Cell Park, LLC (the &#8220;Yaphank Project Company&#8221;) which in turn owns the LIPA Yaphank Project and is the party to the power purchase agreement and all project agreements. At the closing of the transaction, the Yaphank Partnership is owned by Franklin Park, holding Class A Units, and Fuel Cell Energy Finance Holdco, LLC, a subsidiary of FuelCell Energy Finance, LLC, holding Class B Units. The acquisition of the Yaphank Project Company by the Yaphank Partnership was funded in part by an initial draw from Franklin Park and funds contributed downstream to the Yaphank Partnership by the Company. The initial funding occurred on December 13, 2021, upon the satisfaction of certain conditions precedent (including the receipt of an appraisal and confirmation that the LIPA Yaphank Project would be eligible for the investment tax credit (&#8220;ITC&#8221;) under Section 48 of the Internal Revenue Code of 1986, as amended). &#160;In connection with the initial closing, the Company was able to draw down approximately $3.2 million, of which approximately $0.4 million was used to pay closing costs, including title insurance expenses and legal and consulting fees. The Company is eligible to draw the remaining amount of the commitment, approximately $9.2 million, once the LIPA Yaphank Project achieves commercial operation. &#160;When such funds are drawn down, the funds will be distributed upstream to the Company, as a reimbursement of prior construction costs incurred by the Company.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Under a partnership flip structure, tax equity investors agree to receive a minimum target rate of return, typically on an after-tax basis. Prior to receiving a contractual rate of return or a date specified in the contractual arrangements, Franklin Park will receive substantially all of the non-cash value attributable to the LIPA Yaphank Project, which includes accelerated depreciation and Section 48(a) investment tax credits; however, the Company will receive a majority of the cash distributions (based on the operating income of the LIPA Yaphank Project), which are paid quarterly. After Franklin Park receives its contractual rate of return, the Company will receive approximately 95% of the cash and tax allocations. The Company (through a separate wholly owned entity) may enter into a back leverage debt financing transaction and use the cash distributions from the Yaphank Partnership to service the debt. &#160;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Under this partnership flip structure, after the fifth anniversary following commercial operations, we have an option to acquire all of the equity interests that Franklin Park holds in the Yaphank Partnership starting after Franklin Park receives its contractual rate of return (the anticipated &#8220;flip&#8221; date) after the LIPA Yaphank Project is operational.

The Settlement Agreement provides, among other things, that the parties will cooperate in good faith to effect a market transition to the Company of the molten carbonate fuel cell business in Korea in accordance with the terms and conditions of the Settlement Agreement. To that end, the Settlement Agreement provides that any and all past, current, or potential disputes and claims between the Company, on the one hand, and POSCO Energy and KFC, on the other, of any nature whatsoever, whether known or unknown, asserted or not asserted, based on actions or omissions of any party on or before the date of Settlement Agreement are fully and finally settled, including such disputes and claims, directly or indirectly, in connection with the legal disputes (other than the books and records dispute which was previously resolved) and License Agreements described above in Note 22. &#8220;Commitments and Contingencies,&#8221; with the exception of (i) an unfiled claim by the Company in the amount of </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="background:#ffffff;">approximately </span><span style="background:#ffffff;">$1.8</span><span style="background:#ffffff;"> million with respect to certain royalties the Company believes are owed by POSCO Energy with respect to replacement modules deployed by POSCO Energy at Gyenonggi Green Energy and other sites for which POSCO Energy has not paid royalties, and (ii) an unfiled claim by POSCO Energy in an unknown amount with respect to a series of purchase orders for materials and components which began in 2014 under a supply chain contract, both of which claims remain unsettled. The Company does not believe the claim by POSCO Energy with respect to purchase orders for materials and components under the supply chain contract has merit and the Company retains the right to file a counterclaim for damages it believes it has incurred with respect to such supply chain contract. With respect to</span> the attachments obtained by POSCO Energy from the Seoul Central District Court with respect to certain revenues owed to the Company by KOSPO (which are described in more detail in Note 22. &#8220;Commitments and Contingencies&#8221;)<span style="background:#ffffff;">, the Settlement Agreement provides that, within </span><span style="background:#ffffff;">five days</span><span style="background:#ffffff;"> of the date of the Settlement Agreement, POSCO Energy will file an application with the Seoul Central District Court to revoke the attachments. Thereafter, the Company expects to promptly receive the outstanding KOSPO accounts receivable of approximately </span>$11.2 million held by the Seoul Central District Court. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:10pt 0pt 0pt 0pt;">Under the Settlement Agreement, the parties have also agreed that, within five days of the date thereof, the Company will&#160;withdraw its objection to the spin-off of KFC from POSCO Energy, and that the License Agreements are not terminated, but instead are deemed to be amended such that POSCO Energy and KFC only have the right (i) to provide maintenance and repair services to PE Group&#8217;s existing customers on existing molten carbonate power generation and thermal projects under long-term service agreements currently in force as well as long-term service agreements that have expired and are pending renewal as of the settlement date (collectively, &#8220;Existing LTSAs&#8221;), (ii) to supply replacement modules purchased from the Company only for their existing customers for existing molten carbonate power generation and thermal projects under Existing LTSAs and (iii) to own, operate and maintain all facilities and factories solely for the purposes set forth in (i) and (ii) above (collectively, the &#8220;Right to Service License&#8221;). POSCO Energy and KFC further agree that, as of the date of the Settlement Agreement, the License Agreements are deemed to be amended such that the Company exclusively enjoys all rights as to its technology in Korea and Asia, other than the Right to Service License. The Settlement Agreement further provides that the License Agreements will terminate automatically upon sixty days prior written notice to PE Group if (i) the Company enters into a business collaboration agreement with a Korean company to construct, assemble, manufacture, market, sell, distribute, import, export, install, commission, service, maintain, or repair products incorporating the Company&#8217;s technology, or otherwise conduct the Company&#8217;s business, in the Korean market; or (ii) the Company expands the capacity of its existing Korean entity such as to perform such activities itself. In the event of the termination of the License Agreements, the license granted to PE Group under the Right to Service License will continue notwithstanding the termination of the License Agreements, except that PE Group&#8217;s right to own, operate, and maintain all facilities and factories for the purpose of servicing any orders or requests made by the Company will terminate. For the avoidance of doubt, pursuant to the terms of the Settlement Agreement, PE Group has no right to manufacture modules or any other product incorporating the Company&#8217;s technology under the License Agreements as amended, the Right to Service License or otherwise unless requested and authorized by the Company to do so. &#160;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;">The Settlement Agreement further provides that, in order to service its existing customers under the Existing LTSAs, KFC will place a firm, non-cancelable order for twelve SureSource 3000 modules within two weeks after the date of the Settlement Agreement and an additional firm, non-cancelable order for eight SureSource 3000 modules on or before June 30, 2022, all at a price of $3.0 million per module. In addition, KFC agrees to use commercially reasonable efforts to order fourteen additional SureSource 3000 modules by December 31, 2022, at a price of $3.0 million per module if ordered by such date. If KFC materially breaches the Settlement Agreement by failing to make timely and full payment for the modules for which KFC is required to place orders under the Settlement Agreement and does not cure such material breach within fifteen days of notice of such breach by the Company, the License Agreements and the Right to Service License granted to PE Group will be terminated. If the Company materially breaches the Settlement Agreement by failing to supply the modules for which KFC is required to place orders under the Settlement Agreement, as long as KFC has made the payment for such modules and has otherwise satisfied its contractual obligations for those modules and such material breach is not cured within sixty days after notice from PE Group, PE Group will have the right to terminate the Settlement Agreement. With respect to any other alleged breach, material or otherwise, of the Settlement Agreement, the parties&#8217; exclusive remedy consists solely of general damages.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;">Pursuant to the Settlement Agreement, with respect to new modules to be supplied by the Company and deployed by PE Group to its existing customers, the Company will provide its standard warranty against module defects until the earlier of eighteen months from the date of shipment or twelve months from the date of installation. As part of the global settlement of the disputes among the parties and subject to the qualifications set forth in the Settlement Agreement, the Company will reimburse PE Group for any annual output penalty amount paid by PE Group to its customers pursuant to Existing LTSAs (whether such Existing LTSA is extended or renewed), caused by a shortfall or defect in the new modules for a period of up to seven years. The maximum annual reimbursement obligation with regard to any PE Group customer for any new module provided by the Company will not exceed an amount equal to 7.5% per year of the module purchase </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;">price. The Company will not be required to reimburse PE Group for any penalty paid by PE Group under the Existing LTSAs that is not caused by a shortfall or defect in the modules to be supplied by the Company including, without limitation, any shortfall or defect caused by a site-related problem, a problem with the balance of plant, or other components of the project.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;padding-top:10pt;text-align:justify;margin:0pt;">Although the Company has the exclusive and unrestricted right under the Settlement Agreement to perform, pursue, and otherwise conduct its business in relation to new fuel cell projects (including new projects with PE Group&#8217;s existing customers) in Korea and Asia, the parties have agreed that, except as further provided in the Settlement Agreement with respect to PE Group&#8217;s existing customers Noeul Green Energy and Godeok Green Energy, the Company will not engage in discussions with PE Group&#8217;s existing customers regarding Existing LTSAs without PE Group&#8217;s consent. The parties have further agreed that if PE Group cannot enter into an agreement with its existing customers to extend or renew Existing LTSAs by December 31, 2022, PE Group will cooperate with the Company so that the Company may discuss and, at the Company&#8217;s sole discretion, enter into an extension of an Existing LTSA, a new long-term service agreement to replace an Existing LTSA, or a module sales agreement with PE Group&#8217;s existing customers; provided that (i) should the Company enter into such an arrangement with a PE Group existing customer, and (ii) the Company is required to provide replacement modules to such existing customer under such arrangement, and (iii) PE Group has not already deployed all or some the modules that PE Group ordered under Settlement Agreement, the Company will purchase the number of required replacement modules from PE Group at a price of $3.0 million per module (to the extent such modules are available and have not yet been deployed). The purchase of such replacement modules by the Company is contingent upon the modules being in proper condition as determined by inspection process to be agreed by the parties. Any modules purchased by the Company from PE Group under these terms will be included as part of the firm orders KFC is required to make pursuant to the Settlement Agreement.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;">With respect to operations and maintenance agreements, the Settlement Agreement provides that KFC will have the right of first refusal on providing operation and maintenance services on commercially reasonable terms for new long-term service agreements entered into by the Company in Korea for a period of the first to occur of either twenty-four months after the date of the Settlement Agreement or until such time as the Company engages a third party capable of providing such services in Korea. If KFC and the Company agree that KFC should provide operation and maintenance services pursuant to the right of first refusal, KFC and the Company will enter into one or more operation and maintenance agreements that reflect commercially reasonable terms and conditions as agreed by KFC and the Company at that time.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;background:#ffffff;margin:0pt;">&#160;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;">With respect to balance of plant (&#8220;BOP&#8221;), KFC currently has eight units of BOP available, and the Settlement Agreement provides that the Company has the option to purchase such units of BOP for any new molten carbonate fuel cell projects within Korea at a price of KRW 2,550,000,000 per unit. The Company will also have a non-exclusive, non-transferrable, non-sublicensable license to use the intellectual property imbedded in the BOP units in Korea in consideration for a reasonable license fee to be separately agreed by the parties. Detailed terms and conditions of BOP and related software and firmware supply will be discussed and agreed in good faith in separate BOP supply agreements in the event the Company exercises its option to purchase any of such BOP.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;background:#ffffff;margin:0pt;">&#160;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;">The Company&#160;retained outside counsel on a contingency basis to pursue its claims against POSCO Energy and KFC, and outside counsel entered into an agreement with a litigation finance provider to fund the legal fees and expenses of the arbitration proceedings brought by the Company against POSCO Energy and KFC. As the Company has entered into the Settlement Agreement, it is required to remit fees to its counsel, Wiley Rein, LLP (&#8220;Wiley&#8221;), subject to the terms of its engagement letter with Wiley. On December 23, 2021, the Company agreed that it will pay Wiley a total of $24.0 million to satisfy all obligations to Wiley under the Company&#8217;s engagement letter, of which $14.0 million will be paid on or before December 30, 2021, $5.0 million will be paid on or before March 30, 2022, and $5.0 million will be paid on or before June 30, 2022.</p><span></span>

From the date of the Open Market Sale Agreement through October 31, 2021, approximately 44.1 million shares were sold, resulting in gross proceeds to the Company totaling approximately $377.2 million before deducting expenses and sales commissions. Net proceeds to the Company totaled approximately $369.7 million. The Company plans to use the net proceeds from this offering to accelerate the development and commercialization of our Advanced Technologies products, including our solid oxide platform, for project development, for internal research and development, to invest in capacity expansion for solid oxide and carbonate fuel cell manufacturing, and for project financing, working capital support, and general corporate purposes.

The Company expects to seek long-term debt and tax equity (e.g., sale-leaseback and partnership transactions) for its project asset portfolio as these projects commence commercial operations. The proceeds of any such financing, if obtained, may allow the Company to fund other projects. We may also seek to obtain additional financing in both the debt and equity markets in the future.

Under Topic 606: <i style="font-style:italic;">Revenue from Contracts with Customers, </i>the amount of revenue recognized for any goods or services reflects the consideration that the Company expects to be entitled to receive in exchange for those goods and services. To achieve this core principle, the Company applies the following five-step approach: (1)&#160;identify the contract with the customer; (2)&#160;identify the performance obligations in the contract; (3)&#160;determine the transaction price; (4)&#160;allocate the transaction price to performance obligations in the contract; and (5)&#160;recognize revenue when or as a performance obligation is satisfied.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">A contract is accounted for when there has been approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Performance obligations under a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct and are distinct in the context of the contract. In certain instances, the Company has concluded distinct goods or services should be accounted for as a single performance obligation that is a series of distinct goods or services that have the same pattern of transfer to the customer. To the extent a contract includes multiple promised goods or services, the Company must apply judgment to determine whether the customer can benefit from the goods or services either on their own or together with other resources that are readily available to the customer (the goods or services are distinct) and if the promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract (the goods or services are distinct in the context of the contract). If these criteria are not met, the promised services are accounted for as a single performance obligation. The transaction price is determined based on the consideration that the Company will be entitled to in exchange for transferring goods or services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price, generally utilizing the expected value method. Determining the transaction price requires judgment. If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price basis. Standalone selling price is determined by the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price by taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. Performance obligations are satisfied either over time or at a point in time as discussed in further detail below. In addition, the Company&#8217;s contracts with customers generally do not include significant financing components or non-cash consideration. The Company has elected practical expedients in the accounting guidance that allow for revenue to be recorded in the amount that the Company has a right to invoice, if that amount corresponds directly with the value to the customer of the Company&#8217;s performance to date, and that allow the Company not to disclose related unsatisfied performance obligations. The Company records any amounts that are billed to customers in excess of revenue recognized as deferred revenue and revenue recognized in excess of amounts billed to customers as unbilled receivables.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">Revenue streams are classified as follows:</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">Product.</b> Includes the sale of completed project assets, sale and installation of fuel cell power platforms including site engineering and construction services, and the sale of modules, balance of plant (&#8220;BOP&#8221;) components and spare parts to customers.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">Service.</b> Includes performance under long-term service agreements for power platforms owned by third parties.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">License and royalty. </b>Includes license fees and royalty income from the licensure of intellectual property.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"><b style="font-weight:bold;">Generation.</b> Includes the sale of electricity under PPAs and utility tariffs from project assets retained by the Company.

Revenue from most government sponsored Advanced Technologies projects is recognized as direct costs are incurred plus allowable overhead less cost share requirements, if any. Revenue is only recognized to the extent the contracts are funded. Revenue from previous fixed price Advanced Technologies projects is recognized using the cost to cost input method.

The Company recorded license revenue of $4.0 million in association with this agreement for the fiscal&#160;year ended October&#160;31, 2020 which revenue was considered at a point-in-time upon the signing of the contract as the license is considered functional intellectual property because it has standalone functionality.

Such right and license is sublicensable to third parties performing work for or with EMRE or its affiliates, but shall not otherwise be sublicensable. Upon the payment by EMRE to the Company of $10.0 million, which was received by the Company on June&#160;14, 2019, EMRE and its affiliates were fully vested in the rights and licenses granted in the EMRE License Agreement, and any further obligations under the EMRE License Agreement are considered by the Company to be minimal. As a result, the total contract value of $10.0 million was recorded as revenue for the&#160;year ended October&#160;31, 2019.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Generation revenue</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">For certain project assets where customers purchase electricity from the Company under PPAs, the Company has determined that these agreements should be accounted for as operating leases pursuant to ASC&#160;842, <i style="font-style:italic;">Leases</i>. Revenue is recognized when electricity has been delivered based on the amount of electricity delivered at rates specified under the contracts, assuming all other revenue recognition criteria are met. Generation sales, to the extent the related PPAs are within the scope of Topic 606, are recognized as revenue in the period in which the Company provides the electricity and completes the performance obligation, which is the same as the&#160;monthly amount billed to customers.</p><span></span>

The Company has considered the provisions within the financing-related agreements (including the limited liability company agreement for the Groton Partnership) which grant the Company power to manage and make decisions affecting the operations of the Groton Partnership. The Company considers the rights granted to East West Bank under the agreements to be more protective in nature than participatory. Therefore, the Company has determined under the power and benefits criterion of Accounting Standards Codification 810, <i style="font-style:italic;">Consolidations </i>that it is the primary beneficiary of the Groton Partnership. As the primary beneficiary, the Company consolidates in its consolidated financial statements the financial position, results of operations and cash flows of the Groton Partnership, and all intercompany balances and transactions between the Company and the Groton Partnership are eliminated in the consolidated financial statements. The Company recognized East West Bank&#8217;s share of the net assets of the Groton Partnership, which is $3.0 million as of October 31, 2021, as a noncontrolling interest in mezzanine equity on its Consolidated Balance Sheet and will continue to do so until the conditional withdrawal period lapses upon commencement of operations. Upon commencement of operations of the related project asset, the Company expects to allocate profits and losses to the noncontrolling interest under the hypothetical liquidation at book value ("HLBV") method. HLBV is a balance sheet-oriented approach for allocating net income or loss to the noncontrolling interest when there is a complex structure, such as the partnership flip structure.</p><span></span>

Estimates are used in accounting for, among other things, revenue recognition, lease right-of-use assets and liabilities, contract loss accruals, excess, slow-moving and obsolete inventories, product warranty accruals, loss accruals on service agreements, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of goodwill and in-process research and development intangible assets, impairment of long-lived assets (including project assets), and contingencies. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates.</p><span></span>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

<td class="text">On May&#160;9, 2019, in connection with the closing of the purchase of the membership interests of Bridgeport Fuel Cell, LLC (&#8220;BFC&#8221;) (and the 14.9 MW Bridgeport Fuel Cell Project), BFC entered into a subordinated credit agreement with the Connecticut Green Bank whereby Connecticut Green Bank provided financing in the amount of $6.0 million (the &#8220;Subordinated Credit Agreement&#8221;). This $6.0 million consisted of $1.8 million in incremental funding that was received by BFC and $4.2 million of funding previously received by FuelCell Energy,&#160;Inc. with respect to which BFC became the primary obligor. As security for the Subordinated Credit Agreement, Connecticut Green Bank received a perfected lien, subordinated and second in priority to the liens securing the $25.0 million loaned under the BFC Credit Agreement (as defined below), in all of the same collateral securing the BFC Credit Agreement. The interest rate under the Subordinated Credit Agreement is 8% per annum. Principal and interest are due&#160;monthly in amounts sufficient to fully amortize the loan over an 84-month period ending in May&#160;2026. The Subordinated Credit Agreement contains a debt coverage ratio which is required to be maintained and may not be less than 1.10 as of the end of each fiscal quarter, beginning with the quarter ended July&#160;31, 2020. The balance under the Subordinated Credit Agreement as of October&#160;31, 2021 was $4.3 million.<span></span>

The redemption requirement does not constitute an unconditional obligation that will be settled in a variable number of shares constituting a monetary value predominantly indexed to (a) a fixed monetary amount known at inception, (b) an amount inversely correlated with the residual value of the entity, or (c) an amount determined by reference to something other than the fair value of issuer's stock. Does not include mandatorily redeemable stock. The exception is if redemption is required upon liquidation or termination of the reporting entity.</p></div>

From the date of the Open Market Sale Agreement through October 31, 2021, approximately 44.1 million shares were sold, resulting in gross proceeds to the Company totaling approximately $377.2 million before deducting expenses and sales commissions. Net proceeds to the Company totaled approximately $369.7 million. The Company plans to use the net proceeds from this offering to accelerate the development and commercialization of our Advanced Technologies products, including our solid oxide platform, for project development, for internal research and development, to invest in capacity expansion for solid oxide and carbonate fuel cell manufacturing, and for project financing, working capital support, and general corporate purposes. The remaining availability under the Open Market Sale Agreement as of the date of filing of this report is approximately $122.8 million. See Note 15. &#x201c;Stockholders&#x2019; Equity and Warrant Liabilities&#x201d; for additional information regarding the Open Market Sale Agreement.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;We believe that our unrestricted cash and cash equivalents, expected receipts from our contracted backlog, and release of short-term restricted cash less expected disbursements over the next twelve&#160;months will be sufficient to allow the Company&#160;to&#160;meet its obligations for at least one&#160;year from the date of issuance of these financial statements.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;To date, we have not achieved profitable operations or sustained positive cash flow from operations. The Company&#x2019;s future liquidity will depend on its ability to (i)&#160;timely complete current projects in process within budget, (ii)&#160;increase cash flows from its generation operating portfolio, including by meeting conditions required to timely commence operation of new projects, operating its generation operating portfolio in compliance with minimum performance guarantees and operating its generation operating portfolio in accordance with revenue expectations, (iii)&#160;obtain financing for project construction, (iv)&#160;obtain permanent financing for its projects once constructed, (v)&#160;increase order and contract volumes, which would lead to additional product sales, service agreements and generation revenues, (vi)&#160;obtain funding for and receive payment for research and development under current and future Advanced Technologies contracts, (vii) successfully commercialize its Advanced Technologies platforms, including its solid oxide, hydrogen and carbon capture platforms, (viii)&#160;implement the product cost reductions necessary to achieve profitable operations, (ix)&#160;manage working capital and the Company&#x2019;s unrestricted cash balance&#160;and (x)&#160;access the capital markets to raise funds through the sale of equity securities, convertible notes, and other equity-linked instruments.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;We are continually assessing different means by which to accelerate the Company&#x2019;s growth, enter new markets, commercialize new products, and enable capacity expansion. Therefore, from time to time, the Company may consider and enter into agreements for one or more of the following: negotiated financial transactions, minority investments, collaborative ventures, license arrangements, joint ventures or other business transactions for the purpose(s) of geographic or manufacturing expansion and/or new product or technology development and commercialization. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Our business model requires substantial outside financing arrangements and satisfaction of the conditions of such financing arrangements to construct and deploy our projects and facilitate the growth of our business. The Company expects to seek long-term debt and tax equity (e.g., sale-leaseback and partnership transactions) for its project asset portfolio as these projects commence commercial operations. The proceeds of any such financing, if obtained, may allow the Company to fund other projects. We may also seek to obtain additional financing in both the debt and equity markets in the future. If &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;financing is not available to us on acceptable terms if and when needed, or on terms acceptable to us or our lenders, if we do not satisfy the conditions of our financing arrangements, if we spend more than the financing approved for projects, if project costs exceed an amount that the Company can finance, or if we do not generate sufficient revenues or obtain capital sufficient for our corporate needs, we may be required to reduce or slow planned spending, reduce staffing, sell assets, seek alternative financing and take other measures, any of which could have a material adverse effect on our financial condition and operations.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"&gt;Significant Accounting Policies&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="text-decoration-line:underline;text-decoration-style:solid;"&gt;Cash and Cash Equivalents and Restricted Cash&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;All cash equivalents consist of investments in money market funds with original maturities of three&#160;months or less at the date of acquisition. We place our temporary cash investments with high credit quality financial institutions.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="text-decoration-line:underline;text-decoration-style:solid;"&gt;Inventories and Advance Payments to Vendors&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Inventories consist principally of raw materials and work-in-process. Cost is determined using the first-in, first-out cost method. Included in our inventory balance are used modules that are brought back into inventory upon installation of new modules. When a new module is installed, a determination is made as to whether the module has remaining useful life or should be scrapped and materials recycled. Modules that are deemed to have remaining useful life are put into inventory at an estimated value based on the expected remaining life of the module and its projected output. In certain circumstances, we will make advance payments to vendors for future inventory deliveries. These advance payments are recorded as Other current assets on the Consolidated Balance Sheets.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Inventories are reviewed to determine if valuation allowances are required for excess, obsolete, and slow-moving inventory. This review includes analyzing inventory levels of individual parts considering the current design of our products and production requirements as well as the expected inventory requirements for maintenance on installed power platforms and inventory will be recorded at a new cost basis if a valuation allowance is required.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="text-decoration-line:underline;text-decoration-style:solid;"&gt;Project Assets&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Project assets consist of capitalized costs for fuel cell projects in various stages of development, including those projects with respect to which we have entered into power purchase agreements (&#x201c;PPAs&#x201d;), those projects with respect to which we expect to secure long-term contracts and those projects retained by the Company under a merchant model. Such development costs are generally incurred prior to entering into a definitive sales or long-term financing agreement for the project. Project assets also include capitalized costs for fuel cell projects which are the subject of a sale-leaseback transaction with PNC Energy Capital, LLC (&#x201c;PNC&#x201d;) or Crestmark Equipment Finance, a division of MetaBank (&#x201c;Crestmark&#x201d;). Project asset costs include costs for developing and constructing a complete turn-key fuel cell project. Development costs can include legal, consulting, permitting, interconnect, and other similar costs. To the extent we enter into a definitive sales agreement, we expense project assets to cost of sales after the respective project asset is sold to a customer and all revenue recognition criteria have been met.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="text-decoration-line:underline;text-decoration-style:solid;"&gt;Property, Plant and Equipment&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Property, plant and equipment are stated at cost, less accumulated depreciation which is recorded based on the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements are amortized on the straight-line method over the shorter of the estimated useful lives of the assets or the term of the lease. When property is sold or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in operations for the period.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="text-decoration-line:underline;text-decoration-style:solid;"&gt;Goodwill and Indefinite-Lived Intangibles&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in a business combination and is reviewed for impairment at least annually. The intangible asset represents indefinite-lived in-process research and development for cumulative research and development efforts associated with the development of solid oxide fuel cell stationary power generation and is also reviewed at least annually for impairment.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Accounting Standards Codification Topic 350, "Intangibles&#160;- Goodwill and Other" (&#x201c;ASC 350&#x201d;) permits the assessment of qualitative factors to determine whether events and circumstances lead to the conclusion that it is necessary to perform the goodwill impairment test required under ASC 350.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company completed its annual impairment analysis of goodwill and the in-process research&#160;&amp;amp; development assets (&#x201c;IPR&amp;amp;D&#x201d;) as of July&#160;31, 2021. The goodwill and IPR&amp;amp;D asset are both held by the Company&#x2019;s Versa Power Systems,&#160;Inc. (&#x201c;Versa&#x201d;) reporting unit. Goodwill and the IPR&amp;amp;D asset are also reviewed for possible impairment whenever changes in conditions indicate that the fair value of a reporting unit or IPR&amp;amp;D asset is more likely than not below its carrying value. No impairment charges were recorded with respect to goodwill or the IPR&amp;amp;D asset during the fiscal&#160;years ended October&#160;31, 2021, 2020 and 2019.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="text-decoration-line:underline;text-decoration-style:solid;"&gt;Impairment of Long-Lived Assets (including Project Assets)&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. If events or changes in circumstances indicate that the carrying amount of the asset group may not be recoverable, we compare the carrying amount of an asset group to future undiscounted net cash flows, excluding interest costs, expected to be generated by the asset group and their ultimate disposition. If the sum of the undiscounted cash flows is less than the carrying value, the impairment to be recognized is measured by the amount by which the carrying amount of the asset group exceeds the fair value of the asset group.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="text-decoration-line:underline;text-decoration-style:solid;"&gt;Revenue Recognition&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company adopted Accounting Standards Codification (&#x201c;ASC&#x201d;) Topic 606: &lt;i style="font-style:italic;"&gt;Revenue from Contracts with Customers&lt;/i&gt; (&#x201c;Topic 606&#x201d;) effective as of November&#160;1, 2018. Under Topic 606: &lt;i style="font-style:italic;"&gt;Revenue from Contracts with Customers, &lt;/i&gt;the amount of revenue recognized for any goods or services reflects the consideration that the Company expects to be entitled to receive in exchange for those goods and services. To achieve this core principle, the Company applies the following five-step approach: (1)&#160;identify the contract with the customer; (2)&#160;identify the performance obligations in the contract; (3)&#160;determine the transaction price; (4)&#160;allocate the transaction price to performance obligations in the contract; and (5)&#160;recognize revenue when or as a performance obligation is satisfied.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;A contract is accounted for when there has been approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Performance obligations under a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct and are distinct in the context of the contract. In certain instances, the Company has concluded distinct goods or services should be accounted for as a single performance obligation that is a series of distinct goods or services that have the same pattern of transfer to the customer. To the extent a contract includes multiple promised goods or services, the Company must apply judgment to determine whether the customer can benefit from the goods or services either on their own or together with other resources that are readily available to the customer (the goods or services are distinct) and if the promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract (the goods or services are distinct in the context of the contract). If these criteria are not met, the promised services are accounted for as a single performance obligation. The transaction price is determined based on the consideration that the Company will be entitled to in exchange for transferring goods or services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price, generally utilizing the expected value method. Determining the transaction price requires judgment. If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price basis. Standalone selling price is determined by the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price by taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. Performance obligations are satisfied either over time or at a point in time as discussed in further detail below. In addition, the Company&#x2019;s contracts with customers generally do not include significant financing components or non-cash consideration. The Company has elected practical expedients in the accounting guidance that allow for revenue to be recorded in the amount that the Company has a right to invoice, if that amount corresponds directly with the value to the customer of the Company&#x2019;s performance to date, and that allow the Company not to disclose related unsatisfied performance obligations. The Company records any amounts that are billed to customers in excess of revenue recognized as deferred revenue and revenue recognized in excess of amounts billed to customers as unbilled receivables.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Revenue streams are classified as follows:&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"&gt;&lt;b style="font-weight:bold;"&gt;Product.&lt;/b&gt; Includes the sale of completed project assets, sale and installation of fuel cell power platforms including site engineering and construction services, and the sale of modules, balance of plant (&#x201c;BOP&#x201d;) components and spare parts to customers.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"&gt;&lt;b style="font-weight:bold;"&gt;Service.&lt;/b&gt; Includes performance under long-term service agreements for power platforms owned by third parties.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"&gt;&lt;b style="font-weight:bold;"&gt;License and royalty. &lt;/b&gt;Includes license fees and royalty income from the licensure of intellectual property.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"&gt;&lt;b style="font-weight:bold;"&gt;Generation.&lt;/b&gt; Includes the sale of electricity under PPAs and utility tariffs from project assets retained by the Company.

The relative stand-alone selling price is estimated and is used as the basis for allocation of the contract consideration. Revenue is recognized upon the satisfaction of the performance obligations, which includes the transfer of control of the project asset to the customer, which is when the contract is signed and the PPA is assigned to the customer. See below for further discussion regarding revenue recognition for service agreements. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Contractual payments related to the sale of the project asset and assignment of the PPA are generally received up-front. Payment terms for service agreements are generally ratable over the term of the agreement.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Service agreements&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Service agreements represent a single performance obligation whereby the Company performs all required maintenance and monitoring functions, including replacement of modules, to ensure the power platform(s)&#160;under the service agreement generate a minimum power output.&#160;To the extent the power platform(s)&#160;under service agreements do not achieve the minimum power output, certain service agreements include a performance guarantee penalty.&#160;Performance guarantee penalties represent variable consideration, which is estimated for each service agreement based on past experience, using the expected value method.&#160;The consideration for each service agreement is recognized over time using costs incurred to date relative to total estimated costs at completion to measure progress.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company reviews its cost estimates on service agreements on a quarterly basis and records any changes in estimates on a cumulative catch-up basis.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Loss accruals for service agreements are recognized to the extent that the estimated remaining costs to satisfy the performance obligation exceed the estimated remaining unrecognized consideration. Estimated losses are recognized in the period in which losses are identified.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Payment terms for service agreements are generally ratable over the term of the agreement.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Advanced Technologies contracts&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Advanced Technologies contracts include the promise to perform research and development services and, as such, this represents one performance obligation. Revenue from most government sponsored Advanced Technologies projects is recognized as direct costs are incurred plus allowable overhead less cost share requirements, if any. Revenue is only recognized to the extent the contracts are funded. Revenue from previous fixed price Advanced Technologies projects is recognized using the cost to cost input method. Revenue recognition for research performed under the EMRE Joint &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Development Agreement (as defined elsewhere herein) also falls into the practical expedient category where revenue is recorded consistent with the amounts that are to be invoiced.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Payments are based on costs incurred for government sponsored Advanced Technologies projects and upon completion of milestones for previous fixed-price Advanced Technologies projects. Payments under the EMRE Joint Development Agreement are based on time spent and material costs incurred.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;License agreements&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company entered into the License Agreements (as defined elsewhere herein) with POSCO Energy Co.,&#160;Ltd. (&#x201c;POSCO Energy&#x201d;) in 2007, 2009 and 2012. In June&#160;2020, the Company notified POSCO Energy that it was terminating the License Agreements and POSCO Energy disputed such termination (for more information, refer to Note&#160;22. &#x201c;Commitments and Contingencies&#x201d; and Note 24. &#x201c;Subsequent Events&#x201d;). &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Prior to the date of the Company&#x2019;s notice of termination, in connection with the adoption of Topic 606, several performance obligations were identified under the License Agreements, including previously satisfied performance obligations for the transfer of licensed intellectual property, two performance obligations for specified upgrades of the previously licensed intellectual property, a performance obligation to deliver unspecified upgrades to the previously licensed intellectual property on a when-and-if-available basis, and a performance obligation to provide technical support for previously delivered intellectual property.&lt;/p&gt;&lt;table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"&gt;&lt;tr&gt;&lt;td style="width:24.5pt;"/&gt;&lt;td style="font-family:'Times New Roman','Times','serif';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:23.75pt;padding:0pt;"&gt;&#x25cf;&lt;/td&gt;&lt;td style="padding:0pt;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;The performance obligations related to the specified upgrades would have been satisfied and the related consideration recognized as revenue upon the delivery of the specified upgrades. The Company did not recognize any revenue in fiscal&#160;years 2021 and 2020 related to specified upgrades.&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"&gt;&lt;tr&gt;&lt;td style="width:24.5pt;"/&gt;&lt;td style="font-family:'Times New Roman','Times','serif';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:24pt;padding:0pt;"&gt;&#x25cf;&lt;/td&gt;&lt;td style="padding:0pt;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;The performance obligations for unspecified upgrades and technical support were being recognized on a straight-line basis over the license term on the basis that this represented the method that best depicted the progress towards completion of the related performance obligations. The Company recognized revenue totaling &lt;/span&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;$0.8&lt;/span&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt; million for the&#160;year ended October&#160;31, 2020 related to unspecified upgrades and technical support.&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;div style="margin-top:12pt;"/&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;All fixed consideration for the License Agreements was previously collected. The Company discontinued revenue recognition of the deferred license revenue related to the License Agreements in July 2020 given the then pending arbitrations.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company entered into the EMRE Joint Development Agreement on November&#160;5, 2019. The Company recorded license revenue of $4.0 million in association with this agreement for the fiscal&#160;year ended October&#160;31, 2020 which revenue was considered at a point-in-time upon the signing of the contract as the license is considered functional intellectual property because it has standalone functionality. The customer can use this intellectual property as it exists at a point in time and no further services are required from the Company.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Effective as of June&#160;11, 2019, the Company entered into a License Agreement with EMRE (the &#x201c;EMRE License Agreement&#x201d;), pursuant to which the Company agreed, subject to the terms of the EMRE License Agreement, to grant EMRE and its affiliates a non-exclusive, worldwide, fully paid, perpetual, irrevocable, non-transferrable license and right to use the Company&#x2019;s patents, data, know-how, improvements, equipment designs, methods, processes and the like to the extent it is useful to research, develop, and commercially exploit carbonate fuel cells in applications in which the fuel cells concentrate carbon dioxide from industrial and power sources and for any other purpose attendant thereto or associated therewith. Such right and license is sublicensable to third parties performing work for or with EMRE or its affiliates, but shall not otherwise be sublicensable. Upon the payment by EMRE to the Company of $10.0 million, which was received by the Company on June&#160;14, 2019, EMRE and its affiliates were fully vested in the rights and licenses granted in the EMRE License Agreement, and any further obligations under the EMRE License Agreement are considered by the Company to be minimal. As a result, the total contract value of $10.0 million was recorded as revenue for the&#160;year ended October&#160;31, 2019.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Generation revenue&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;For certain project assets where customers purchase electricity from the Company under PPAs, the Company has determined that these agreements should be accounted for as operating leases pursuant to ASC&#160;842, &lt;i style="font-style:italic;"&gt;Leases&lt;/i&gt;. Revenue is recognized when electricity has been delivered based on the amount of electricity delivered at rates specified under the contracts, assuming all other revenue recognition criteria are met. Generation sales, to the extent the related PPAs are within the scope of Topic 606, are recognized as revenue in the period in which the Company provides the electricity and completes the performance obligation, which is the same as the&#160;monthly amount billed to customers.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="font-weight:normal;text-decoration-color:#000000;text-decoration-line:underline;text-decoration-style:solid;"&gt;Variable Interest Entity and Noncontrolling Interests&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:12pt;text-align:justify;margin:0pt;"&gt;&lt;span style="font-size:10pt;"&gt;The Company closed on a tax equity financing transaction in August 2021 f&lt;/span&gt;&lt;span style="font-size:10pt;background:#ffffff;"&gt;or the&#160;7.4&#160;MW fuel cell project (the &#x201c;Groton Project&#x201d;) located on the U.S. Navy Submarine Base in Groton, CT, &lt;/span&gt;&lt;span style="font-size:10pt;"&gt;which has been structured as a &#x201c;partnership flip.&#x201d; A partnership (the &#x201c;Groton Partnership&#x201d;) was organized with East West Bancorp, Inc. (&#x201c;East West Bank&#x201d;) to acquire from FuelCell Energy Finance II, LLC all of the outstanding equity interests in Groton Station Fuel Cell, LLC (&#x201c;Groton Project Company&#x201d;). East West Bank has a conditional withdrawal right which they can exercise and which would require the Company to pay &lt;/span&gt;&lt;span style="font-size:10pt;"&gt;101%&lt;/span&gt;&lt;span style="font-size:10pt;"&gt; of the amount contributed by East West Bank &#160;to date. In addition, under this partnership flip structure, the Company has an option to acquire all of the equity interests that East West Bank holds in the Groton Partnership starting approximately &lt;/span&gt;&lt;span style="-sec-ix-hidden:Hidden_DmeM0wKnqEqwnMBEZ2fX2A;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;five&lt;/span&gt;&lt;/span&gt;&lt;span style="font-size:10pt;"&gt; and a half years after the Groton Project is operational. If the Company exercises this option, the exercise price to be paid by the Company will be the greater of&lt;/span&gt; &lt;span style="font-size:10pt;"&gt;(1) the fair market value of East West Bank&#x2019;s equity interest at the time the option is exercised, (2) five percent of the $15 million tax equity commitment and (3) East West Bank&#x2019;s claim in liquidation determined using the hypothetical liquidation at book value method.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;The Groton Partnership is a Variable Interest Entity (VIE) under U.S. GAAP. The Company has determined that it is the primary beneficiary in the Groton Partnership for accounting purposes. The Company has considered the provisions within the financing-related agreements (including the limited liability company agreement for the Groton Partnership) which grant the Company power to manage and make decisions affecting the operations of the Groton Partnership. The Company considers the rights granted to East West Bank under the agreements to be more protective in nature than participatory. Therefore, the Company has determined under the power and benefits criterion of Accounting Standards Codification 810, &lt;i style="font-style:italic;"&gt;Consolidations &lt;/i&gt;that it is the primary beneficiary of the Groton Partnership. As the primary beneficiary, the Company consolidates in its consolidated financial statements the financial position, results of operations and cash flows of the Groton Partnership, and all intercompany balances and transactions between the Company and the Groton Partnership are eliminated in the consolidated financial statements. The Company recognized East West Bank&#x2019;s share of the net assets of the Groton Partnership, which is $3.0 million as of October 31, 2021, as a noncontrolling interest in mezzanine equity on its Consolidated Balance Sheet and will continue to do so until the conditional withdrawal period lapses upon commencement of operations. Upon commencement of operations of the related project asset, the Company expects to allocate profits and losses to the noncontrolling interest under the hypothetical liquidation at book value ("HLBV") method. HLBV is a balance sheet-oriented approach for allocating net income or loss to the noncontrolling interest when there is a complex structure, such as the partnership flip structure.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="text-decoration-color:#000000;text-decoration-line:underline;text-decoration-style:solid;"&gt;Sale-Leaseback Accounting&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company, through certain wholly-owned subsidiaries, has entered into sale-leaseback transactions for commissioned project assets where we have entered into a PPA with a customer who is both the site host and end user of the power. Due to the Company not meeting criteria to account for the transfer of the project assets as a sale, sale accounting is precluded. Accordingly, the Company uses the financing method to account for these transactions.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Under the financing method of accounting for a sale-leaseback, the Company does not derecognize the project assets and does not recognize as revenue any of the sale proceeds received from the lessor that contractually constitutes payment to acquire the assets subject to these arrangements. Instead, the sale proceeds received are accounted for as financing obligations and leaseback payments made by the Company are allocated between interest expense and a reduction to the financing obligation. Interest on the financing obligation is calculated using the Company&#x2019;s incremental borrowing rate at the inception of the arrangement on the outstanding financing obligation. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="text-decoration-line:underline;text-decoration-style:solid;"&gt;Service Expense Recognition&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;We warranty our products for a specific period of time against manufacturing or performance defects. Our U.S. warranty is generally limited to a term of 15&#160;months after shipment or 12&#160;months after acceptance of our products. We accrue for estimated future warranty costs based on historical experience. We also provide for a specific accrual if there is a known issue requiring repair during the warranty period. Estimates used to record warranty accruals are updated as we gain further operating experience.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;In addition to the standard product warranty, we have entered into service agreements with certain customers to provide monitoring, maintenance and repair services for fuel cell power platforms. Under the terms of these service agreements, the power platform must meet a minimum operating output during the term. If the minimum output falls below the contract requirement, we may be subject to performance penalties or may be required to repair and/or replace the customer&#x2019;s fuel cell module.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company records loss accruals for service agreements when the estimated cost of future module exchanges and maintenance and monitoring activities exceeds the remaining unrecognized contract value. Estimates for future costs on service agreements are determined by a number of factors including the estimated remaining life of the module, used replacement modules available and future operating plans for the power platform. Our estimates are performed on a contract by contract basis and include cost assumptions based on what we anticipate the service requirements will be to fulfill obligations for each contract.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;At the end of our service agreements, customers are expected to either renew the service agreement or, based on the Company&#x2019;s rights to title of the module, the module will be returned to the Company as the platform is no longer being maintained.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="text-decoration-line:underline;text-decoration-style:solid;"&gt;Research and Development Costs&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;We perform both customer-sponsored research and development projects based on contractual agreements with customers and company-sponsored research and development projects.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Costs incurred for customer-sponsored projects include manufacturing and engineering labor, applicable overhead expenses, materials to build and test prototype units and other costs associated with customer-sponsored research and development contracts. Costs incurred for customer-sponsored projects are recorded as cost of Advanced Technologies contract revenues in the Consolidated Statements of Operations and Comprehensive Loss.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Costs incurred for company-sponsored research and development projects consist primarily of labor, overhead, materials to build and test prototype units and consulting fees.

For the&#160;years ended October&#160;31, 2021, 2020 and 2019, our top customers accounted for 79%, 80% and 77%, respectively, of our total annual consolidated revenue.&lt;/p&gt;&lt;p

Estimates are used in accounting for, among other things, revenue recognition, lease right-of-use assets and liabilities, contract loss accruals, excess, slow-moving and obsolete inventories, product warranty accruals, loss accruals on service agreements, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of goodwill and in-process research and development intangible assets, impairment of long-lived assets (including project assets), and contingencies. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="text-decoration-line:underline;text-decoration-style:solid;"&gt;Foreign Currency Translation&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The translation of the financial statements of FCE Korea&#160;Ltd., FCES GmbH and Versa Power Systems&#160;Ltd. results in translation gains or losses, which are recorded in accumulated other comprehensive loss within stockholders&#x2019; equity.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Our Canadian subsidiary, FCE FuelCell Energy&#160;Ltd., is financially and operationally integrated and the functional currency is the U.S. dollar.

The Company&#x2019;s future liquidity will depend on its ability to (i)&#160;timely complete current projects in process within budget, (ii)&#160;increase cash flows from its generation operating portfolio, including by meeting conditions required to timely commence operation of new projects, operating its generation operating portfolio in compliance with minimum performance guarantees and operating its generation operating portfolio in accordance with revenue expectations, (iii)&#160;obtain financing for project construction, (iv)&#160;obtain permanent financing for its projects once constructed, (v)&#160;increase order and contract volumes, which would lead to additional product sales, service agreements and generation revenues, (vi)&#160;obtain funding for and receive payment for research and development under current and future Advanced Technologies contracts, (vii) successfully commercialize its Advanced Technologies platforms, including its solid oxide, hydrogen and carbon capture platforms, (viii)&#160;implement the product cost reductions necessary to achieve profitable operations, (ix)&#160;manage working capital and the Company&#x2019;s unrestricted cash balance&#160;and (x)&#160;access the capital markets to raise funds through the sale of equity securities, convertible notes, and other equity-linked instruments.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;We are continually assessing different means by which to accelerate the Company&#x2019;s growth, enter new markets, commercialize new products, and enable capacity expansion. Therefore, from time to time, the Company may consider and enter into agreements for one or more of the following: negotiated financial transactions, minority investments, collaborative ventures, license arrangements, joint ventures or other business transactions for the purpose(s) of geographic or manufacturing expansion and/or new product or technology development and commercialization. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Our business model requires substantial outside financing arrangements and satisfaction of the conditions of such financing arrangements to construct and deploy our projects and facilitate the growth of our business. The Company expects to seek long-term debt and tax equity (e.g., sale-leaseback and partnership transactions) for its project asset portfolio as these projects commence commercial operations. The proceeds of any such financing, if obtained, may allow the Company to fund other projects. We may also seek to obtain additional financing in both the debt and equity markets in the future. If &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;financing is not available to us on acceptable terms if and when needed, or on terms acceptable to us or our lenders, if we do not satisfy the conditions of our financing arrangements, if we spend more than the financing approved for projects, if project costs exceed an amount that the Company can finance, or if we do not generate sufficient revenues or obtain capital sufficient for our corporate needs, we may be required to reduce or slow planned spending, reduce staffing, sell assets, seek alternative financing and take other measures, any of which could have a material adverse effect on our financial condition and operations.&lt;/p&gt;</fcel:LiquidityPolicyTextBlock>

Under Topic 606: &lt;i style="font-style:italic;"&gt;Revenue from Contracts with Customers, &lt;/i&gt;the amount of revenue recognized for any goods or services reflects the consideration that the Company expects to be entitled to receive in exchange for those goods and services. To achieve this core principle, the Company applies the following five-step approach: (1)&#160;identify the contract with the customer; (2)&#160;identify the performance obligations in the contract; (3)&#160;determine the transaction price; (4)&#160;allocate the transaction price to performance obligations in the contract; and (5)&#160;recognize revenue when or as a performance obligation is satisfied.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;A contract is accounted for when there has been approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Performance obligations under a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct and are distinct in the context of the contract. In certain instances, the Company has concluded distinct goods or services should be accounted for as a single performance obligation that is a series of distinct goods or services that have the same pattern of transfer to the customer. To the extent a contract includes multiple promised goods or services, the Company must apply judgment to determine whether the customer can benefit from the goods or services either on their own or together with other resources that are readily available to the customer (the goods or services are distinct) and if the promise to transfer the goods or services to the customer is separately identifiable from other promises in the contract (the goods or services are distinct in the context of the contract). If these criteria are not met, the promised services are accounted for as a single performance obligation. The transaction price is determined based on the consideration that the Company will be entitled to in exchange for transferring goods or services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price, generally utilizing the expected value method. Determining the transaction price requires judgment. If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price basis. Standalone selling price is determined by the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price by taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. Performance obligations are satisfied either over time or at a point in time as discussed in further detail below. In addition, the Company&#x2019;s contracts with customers generally do not include significant financing components or non-cash consideration. The Company has elected practical expedients in the accounting guidance that allow for revenue to be recorded in the amount that the Company has a right to invoice, if that amount corresponds directly with the value to the customer of the Company&#x2019;s performance to date, and that allow the Company not to disclose related unsatisfied performance obligations. The Company records any amounts that are billed to customers in excess of revenue recognized as deferred revenue and revenue recognized in excess of amounts billed to customers as unbilled receivables.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Revenue streams are classified as follows:&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"&gt;&lt;b style="font-weight:bold;"&gt;Product.&lt;/b&gt; Includes the sale of completed project assets, sale and installation of fuel cell power platforms including site engineering and construction services, and the sale of modules, balance of plant (&#x201c;BOP&#x201d;) components and spare parts to customers.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"&gt;&lt;b style="font-weight:bold;"&gt;Service.&lt;/b&gt; Includes performance under long-term service agreements for power platforms owned by third parties.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"&gt;&lt;b style="font-weight:bold;"&gt;License and royalty. &lt;/b&gt;Includes license fees and royalty income from the licensure of intellectual property.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 24.5pt;"&gt;&lt;b style="font-weight:bold;"&gt;Generation.&lt;/b&gt; Includes the sale of electricity under PPAs and utility tariffs from project assets retained by the Company.

The relative stand-alone selling price is estimated and is used as the basis for allocation of the contract consideration. Revenue is recognized upon the satisfaction of the performance obligations, which includes the transfer of control of the project asset to the customer, which is when the contract is signed and the PPA is assigned to the customer. See below for further discussion regarding revenue recognition for service agreements. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Contractual payments related to the sale of the project asset and assignment of the PPA are generally received up-front. Payment terms for service agreements are generally ratable over the term of the agreement.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Service agreements&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Service agreements represent a single performance obligation whereby the Company performs all required maintenance and monitoring functions, including replacement of modules, to ensure the power platform(s)&#160;under the service agreement generate a minimum power output.&#160;To the extent the power platform(s)&#160;under service agreements do not achieve the minimum power output, certain service agreements include a performance guarantee penalty.&#160;Performance guarantee penalties represent variable consideration, which is estimated for each service agreement based on past experience, using the expected value method.&#160;The consideration for each service agreement is recognized over time using costs incurred to date relative to total estimated costs at completion to measure progress.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company reviews its cost estimates on service agreements on a quarterly basis and records any changes in estimates on a cumulative catch-up basis.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Loss accruals for service agreements are recognized to the extent that the estimated remaining costs to satisfy the performance obligation exceed the estimated remaining unrecognized consideration. Estimated losses are recognized in the period in which losses are identified.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Payment terms for service agreements are generally ratable over the term of the agreement.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Advanced Technologies contracts&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Advanced Technologies contracts include the promise to perform research and development services and, as such, this represents one performance obligation. Revenue from most government sponsored Advanced Technologies projects is recognized as direct costs are incurred plus allowable overhead less cost share requirements, if any. Revenue is only recognized to the extent the contracts are funded. Revenue from previous fixed price Advanced Technologies projects is recognized using the cost to cost input method. Revenue recognition for research performed under the EMRE Joint &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Development Agreement (as defined elsewhere herein) also falls into the practical expedient category where revenue is recorded consistent with the amounts that are to be invoiced.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Payments are based on costs incurred for government sponsored Advanced Technologies projects and upon completion of milestones for previous fixed-price Advanced Technologies projects. Payments under the EMRE Joint Development Agreement are based on time spent and material costs incurred.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;License agreements&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company entered into the License Agreements (as defined elsewhere herein) with POSCO Energy Co.,&#160;Ltd. (&#x201c;POSCO Energy&#x201d;) in 2007, 2009 and 2012. In June&#160;2020, the Company notified POSCO Energy that it was terminating the License Agreements and POSCO Energy disputed such termination (for more information, refer to Note&#160;22. &#x201c;Commitments and Contingencies&#x201d; and Note 24. &#x201c;Subsequent Events&#x201d;). &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Prior to the date of the Company&#x2019;s notice of termination, in connection with the adoption of Topic 606, several performance obligations were identified under the License Agreements, including previously satisfied performance obligations for the transfer of licensed intellectual property, two performance obligations for specified upgrades of the previously licensed intellectual property, a performance obligation to deliver unspecified upgrades to the previously licensed intellectual property on a when-and-if-available basis, and a performance obligation to provide technical support for previously delivered intellectual property.&lt;/p&gt;&lt;table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"&gt;&lt;tr&gt;&lt;td style="width:24.5pt;"/&gt;&lt;td style="font-family:'Times New Roman','Times','serif';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:23.75pt;padding:0pt;"&gt;&#x25cf;&lt;/td&gt;&lt;td style="padding:0pt;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;The performance obligations related to the specified upgrades would have been satisfied and the related consideration recognized as revenue upon the delivery of the specified upgrades.

The Company recognized revenue totaling &lt;/span&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;$0.8&lt;/span&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt; million for the&#160;year ended October&#160;31, 2020 related to unspecified upgrades and technical support.&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;div style="margin-top:12pt;"/&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;All fixed consideration for the License Agreements was previously collected. The Company discontinued revenue recognition of the deferred license revenue related to the License Agreements in July 2020 given the then pending arbitrations.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company entered into the EMRE Joint Development Agreement on November&#160;5, 2019. The Company recorded license revenue of $4.0 million in association with this agreement for the fiscal&#160;year ended October&#160;31, 2020 which revenue was considered at a point-in-time upon the signing of the contract as the license is considered functional intellectual property because it has standalone functionality. The customer can use this intellectual property as it exists at a point in time and no further services are required from the Company.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Effective as of June&#160;11, 2019, the Company entered into a License Agreement with EMRE (the &#x201c;EMRE License Agreement&#x201d;), pursuant to which the Company agreed, subject to the terms of the EMRE License Agreement, to grant EMRE and its affiliates a non-exclusive, worldwide, fully paid, perpetual, irrevocable, non-transferrable license and right to use the Company&#x2019;s patents, data, know-how, improvements, equipment designs, methods, processes and the like to the extent it is useful to research, develop, and commercially exploit carbonate fuel cells in applications in which the fuel cells concentrate carbon dioxide from industrial and power sources and for any other purpose attendant thereto or associated therewith. Such right and license is sublicensable to third parties performing work for or with EMRE or its affiliates, but shall not otherwise be sublicensable. Upon the payment by EMRE to the Company of $10.0 million, which was received by the Company on June&#160;14, 2019, EMRE and its affiliates were fully vested in the rights and licenses granted in the EMRE License Agreement, and any further obligations under the EMRE License Agreement are considered by the Company to be minimal. As a result, the total contract value of $10.0 million was recorded as revenue for the&#160;year ended October&#160;31, 2019.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Generation revenue&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;For certain project assets where customers purchase electricity from the Company under PPAs, the Company has determined that these agreements should be accounted for as operating leases pursuant to ASC&#160;842, &lt;i style="font-style:italic;"&gt;Leases&lt;/i&gt;. Revenue is recognized when electricity has been delivered based on the amount of electricity delivered at rates specified under the contracts, assuming all other revenue recognition criteria are met. Generation sales, to the extent the related PPAs are within the scope of Topic 606, are recognized as revenue in the period in which the Company provides the electricity and completes the performance obligation, which is the same as the&#160;monthly amount billed to customers.&lt;/p&gt;</us-gaap:RevenueRecognitionPolicyTextBlock>

The Company has determined that it is the primary beneficiary in the Groton Partnership for accounting purposes. The Company has considered the provisions within the financing-related agreements (including the limited liability company agreement for the Groton Partnership) which grant the Company power to manage and make decisions affecting the operations of the Groton Partnership. The Company considers the rights granted to East West Bank under the agreements to be more protective in nature than participatory. Therefore, the Company has determined under the power and benefits criterion of Accounting Standards Codification 810, &lt;i style="font-style:italic;"&gt;Consolidations &lt;/i&gt;that it is the primary beneficiary of the Groton Partnership. As the primary beneficiary, the Company consolidates in its consolidated financial statements the financial position, results of operations and cash flows of the Groton Partnership, and all intercompany balances and transactions between the Company and the Groton Partnership are eliminated in the consolidated financial statements. The Company recognized East West Bank&#x2019;s share of the net assets of the Groton Partnership, which is $3.0 million as of October 31, 2021, as a noncontrolling interest in mezzanine equity on its Consolidated Balance Sheet and will continue to do so until the conditional withdrawal period lapses upon commencement of operations. Upon commencement of operations of the related project asset, the Company expects to allocate profits and losses to the noncontrolling interest under the hypothetical liquidation at book value ("HLBV") method. HLBV is a balance sheet-oriented approach for allocating net income or loss to the noncontrolling interest when there is a complex structure, such as the partnership flip structure.&lt;/p&gt;</us-gaap:ConsolidationVariableInterestEntityPolicy>

Instead, the sale proceeds received are accounted for as financing obligations and leaseback payments made by the Company are allocated between interest expense and a reduction to the financing obligation. Interest on the financing obligation is calculated using the Company&#x2019;s incremental borrowing rate at the inception of the arrangement on the outstanding financing obligation. &lt;/p&gt;</us-gaap:RevenueRecognitionLeases>

If the minimum output falls below the contract requirement, we may be subject to performance penalties or may be required to repair and/or replace the customer&#x2019;s fuel cell module.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company records loss accruals for service agreements when the estimated cost of future module exchanges and maintenance and monitoring activities exceeds the remaining unrecognized contract value. Estimates for future costs on service agreements are determined by a number of factors including the estimated remaining life of the module, used replacement modules available and future operating plans for the power platform. Our estimates are performed on a contract by contract basis and include cost assumptions based on what we anticipate the service requirements will be to fulfill obligations for each contract.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;At the end of our service agreements, customers are expected to either renew the service agreement or, based on the Company&#x2019;s rights to title of the module, the module will be returned to the Company as the platform is no longer being maintained.&lt;/p&gt;</fcel:WarrantyAndServiceExpenseRecognitionPolicyPolicyTextBlock>

Estimates are used in accounting for, among other things, revenue recognition, lease right-of-use assets and liabilities, contract loss accruals, excess, slow-moving and obsolete inventories, product warranty accruals, loss accruals on service agreements, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of goodwill and in-process research and development intangible assets, impairment of long-lived assets (including project assets), and contingencies. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates.&lt;/p&gt;</us-gaap:UseOfEstimates>

The contract assets relate to the Company&#x2019;s rights to consideration for work completed but not billed. These amounts are included on a separate line item as Unbilled receivables, and balances expected to be billed later than one&#160;year from the balance sheet date are included within Other assets on the accompanying Consolidated Balance Sheets. The net change in contract assets represents amounts recognized as revenue offset by customer billings. &#160;For the years ended October 31, 2021 and 2020, a total of $5.2 million and $5.9 million, respectively, was transferred to accounts receivable from contract assets recognized at the beginning of the period.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Contract&#160;liabilities&#160;as&#160;of&#160;October&#160;31,&#160;2021&#160;and&#160;2020&#160;were&#160;$36.7&#160;million&#160;and&#160;$41.9 million, respectively. The contract liabilities relate to the advance billings to customers for services that will be recognized over time and in some instances for deferred revenue relating to license performance obligations that will be recognized at a future point in time. The Company discontinued revenue recognition of the deferred license revenue related to the License Agreements in July 2020 given the then pending arbitrations. As of October&#160;31, 2021 and 2020, $22.2 million related to the License Agreements is included within Long-term deferred revenue on the accompanying Consolidated Balance Sheets. As a result of the Settlement Agreement and the anticipated sale of modules to KFC under the Settlement Agreement (Refer to Note 24. &#x201c;Subsequent Events&#x201d; for additional details), the Company will evaluate the future revenue recognition of this deferred revenue in the first quarter of fiscal year 2022. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The net change in contract liabilities represents customer billings offset by revenue recognized. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;&lt;i style="font-style:italic;"&gt;Remaining Performance Obligations&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Remaining performance obligations are the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied.

Service revenue in periods in which there are no module exchanges is expected to be relatively consistent from period to period, whereas module exchanges will result in an increase in revenue when replacements occur.&lt;/p&gt;</us-gaap:RevenueFromContractWithCustomerTextBlock>

Acquisition&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On October&#160;31, 2018, FuelCell Energy Finance, LLC (&#x201c;FuelCell Finance&#x201d;) entered into a membership interest purchase agreement (the &#x201c;Bridgeport Power Purchase Agreement&#x201d;) with Dominion Generation,&#160;Inc., as amended on January&#160;15, 2019 and May&#160;9, 2019, pursuant to which FuelCell Finance purchased (on May&#160;9, 2019) all of the outstanding membership interests in Dominion Bridgeport Fuel Cell, LLC (which is now known as Bridgeport Fuel Cell, LLC) (&#x201c;BFC&#x201d;). BFC owns a 14.9 MW fuel cell park in Bridgeport, Connecticut (the &#x201c;Bridgeport Fuel Cell Project&#x201d;), which the Company originally developed and constructed and has been operating for Dominion Generation,&#160;Inc. under a service agreement since December&#160;2013.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On May&#160;9, 2019, FuelCell Finance closed on the purchase of BFC for a total cash purchase price of $35.5 million, subject to a dollar-for-dollar post-closing adjustment to the extent that the closing working capital was greater or less than $1.0 million (the &#x201c;BFC Purchase Price&#x201d;).&#160;The Company recorded a working capital adjustment of $0.6 million, which has been included in the BFC Purchase Price. Certain balance sheet accounts as of the transaction date, May&#160;9, 2019, relating to the Bridgeport Fuel Cell Project service agreement (accounts receivable of $2.7 million, unbilled receivables of $15.3 million and accrued performance guarantees of $1.3 million) were settled in connection with the acquisition and accordingly were included in the consideration for the acquisition.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The acquisition was funded by loans from Fifth Third Bank, Liberty Bank and Connecticut Green Bank (refer to Note&#160;14. &#x201c;Debt and Financing Obligations&#x201d; for more information).&#160;The balance of the financing for the acquisition was funded by the $15 million of restricted cash on hand that was tied to the Bridgeport Fuel Cell Project and released at closing.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;ASC Topic 805, &#x201c;Business Combinations&#x201d; states that a business is an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs, or other economic benefits directly to investors or other owners, members, or participants.&#160;As the acquisition did not meet the definition of a business combination under ASC 805, the Company accounted for the transaction as an asset acquisition. In an asset acquisition, goodwill is not recognized, but rather any excess consideration transferred over the fair value of the net assets acquired is allocated on a relative fair value basis to the identifiable net assets. The Company determined the estimated fair values of net assets acquired using Level 3 inputs after review and consideration of relevant information, including discounted cash flows, quoted market prices and estimates made by management. The acquisition of BFC also included a PPA with Connecticut Light and Power that has favorable terms relative to market, a land lease with the City of Bridgeport, and working capital.&#160;A pre-existing service agreement was determined to be priced similar to current market rates and no gain or loss was recorded. A total of $38.8 million of consideration was allocated to the fuel cell power platform installation, which is recorded in Project Assets, a total of $12.3 million of consideration was allocated to the PPA, which is recorded as an intangible asset, and the remaining consideration was allocated to the acquired working capital.&#160;The project asset and PPA intangible asset will be depreciated and amortized over their respective useful lives.&#160;Additionally, the land lease with the City of Bridgeport was not assigned any consideration due to its insignificant value.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;The major depreciable assets of the Bridgeport Fuel Cell Project are the fuel cell modules, which are being depreciated over their estimated remaining useful lives of approximately &lt;span style="-sec-ix-hidden:Hidden_Hf9iFhSmTkmn6qlHjRmHeg;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;one&lt;/span&gt;&lt;/span&gt; to seven years, and BOP assets, which are being depreciated over their estimated remaining useful lives of approximately 15 years.

Tax Equity Financing&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;The Company closed on a tax equity financing transaction in August 2021 with East West Bank for the 7.4 MW Groton Project located on the U.S. Navy Submarine Base in Groton, CT, also known as the Submarine Force. East West Bank&#x2019;s tax equity commitment totals $15 million.&#160;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="margin-bottom:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;This transaction was structured as a &#x201c;partnership flip&#x201d;, which is a structure commonly used by tax equity investors in the financing of renewable energy projects. Under this partnership flip structure, a partnership, in this case Groton Station Fuel Cell Holdco, LLC (the &#x201c;Groton Partnership&#x201d;) was organized to acquire from FuelCell Energy Finance II, LLC, a wholly-owned subsidiary of the Company, all outstanding equity interests in Groton Station Fuel Cell, LLC (the &#x201c;Groton Project Company&#x201d;) which in turn owns the Groton Project and is the party to the power purchase agreement and all project agreements. At the closing of the transaction, the Groton Partnership is owned by East West Bank, holding Class A Units, and Fuel Cell Energy Finance Holdco, LLC, a subsidiary of FuelCell Energy Finance, LLC, holding Class B Units. &#160;The acquisition of the Groton Project Company by the Groton Partnership was funded in part by an initial draw from East West Bank and funds contributed downstream to the Groton Partnership by the Company. The initial closing occurred on August 4, 2021, upon the satisfaction of certain conditions precedent (including the receipt of an appraisal and confirmation that the Groton Project would be eligible for the investment tax credit under Section 48 of the Internal Revenue Code of 1986, as amended). &#160;In connection with the initial closing, the Company was able to draw down $3.0 million, of which approximately $0.8 million was used to pay closing costs including appraisal fees, title insurance expenses and legal and consulting fees. The Company is eligible to draw the remaining amount of the commitment, approximately $12 million, once the Groton Project achieves commercial operation. &#160;When such funds are drawn down, the funds will be distributed upstream to the Company, as a reimbursement of prior construction costs incurred by the Company. The Company recognized a loss of $30 thousand for the fiscal year ended October 31, 2021 which is attributable to the noncontrolling interest reflecting the 1% conditional withdrawal.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="margin-bottom:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Under most partnership flip structures, tax equity investors agree to receive a minimum target rate of return, typically on an after-tax basis. Prior to receiving a contractual rate of return or a date specified in the contractual arrangements, East West Bank will receive substantially all of the non-cash value attributable to the Groton Project, which includes accelerated depreciation and Section 48(a) investment tax credits; however, the Company will receive a majority of the cash distributions (based on the operating income of the Groton Project), which are paid quarterly. After East West Bank receives its contractual rate of return, the Company will receive approximately 95% of the cash and tax allocations. The &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Company (through a separate wholly owned entity) may enter into a back leverage debt financing transaction and use the cash distributions from the Groton Partnership to service the debt.&lt;/p&gt;</fcel:TaxEquityFinancingDisclosureTextBlock>

Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statement of Operations.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Standard provides entities with several practical expedient elections. Among them, the Company elected the package of practical expedients that permits the Company to not reassess prior conclusions related to its leasing arrangements, lease classifications and initial direct costs. In addition, the Company has elected the practical expedients to not separate lease and non-lease components, to use hindsight in determining the lease terms and impairment of ROU assets, and to not apply the Standard&#x2019;s recognition requirements to short-term leases with a term of 12&#160;months or less.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The adoption of the Standard did not have a material effect on the Company&#x2019;s Consolidated Statements of Operations and Comprehensive Loss or Consolidated Statement of Cash Flows. Upon adoption, the Company recorded a $10.3 million operating lease ROU asset and a $10.1 million operating lease liability. The adoption of the New Lease Accounting Standard had no impact on accumulated deficit.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company enters into operating and finance lease agreements for the use of real estate, vehicles, information technology equipment, and certain other equipment. We determine if an arrangement contains a lease at inception, which is the date on which the terms of the contract are agreed to and the agreement creates enforceable rights and obligations. The impacts of accounting for operating leases are included in Operating lease right-of-use assets, Operating lease liabilities, and Long-term operating lease liabilities in the Company&#x2019;s Consolidated Balance Sheets. Finance leases are not considered significant to the Company&#x2019;s Consolidated Balance Sheets or Consolidated Statements of Operations and Comprehensive Loss. Finance lease ROU assets at October&#160;31, 2021 and 2020 of $0.1 million and $0.04 million, respectively, are included in Property, plant and equipment, net in the Company&#x2019;s Consolidated Balance Sheets. Finance lease liabilities at October&#160;31, 2021 and 2020 of $0.1 million and $0.04 million, respectively, are included in Current portion of long-term debt and &lt;span style="-sec-ix-hidden:Hidden_705130pvx0GZM-jE7WnSTQ;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;Long-term debt&lt;/span&gt;&lt;/span&gt; and other liabilities in the Company&#x2019;s Consolidated Balance Sheets.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;ROU assets represent the Company&#x2019;s right to use an underlying asset for the lease term and lease liabilities represent the present value of the Company&#x2019;s obligation to make lease payments arising from the lease over the lease term at the commencement date of the lease (or November&#160;1, 2019 for leases existing upon the adoption of ASC 842). As most of the Company&#x2019;s leases do not provide an implicit rate, the Company estimated the incremental borrowing rate based on the information available at the date of adoption in determining the present value of lease payments and used the implicit rate when readily determinable. The Company determined incremental borrowing rates through market sources for secured borrowings including relevant industry rates. The Company&#x2019;s operating lease ROU assets also include any lease pre-payments and exclude lease incentives. Certain of the Company&#x2019;s leases include variable payments, which may vary based upon changes in facts or circumstances after the start of the lease. The Company excludes variable payments from lease ROU assets and lease liabilities to the extent not considered in-substance fixed, and instead, expenses variable payments as incurred. Variable lease expense and lease expense for short term contracts are not material components of lease expense. The Company&#x2019;s leases generally have remaining lease terms of &lt;span style="-sec-ix-hidden:Hidden_Q0t8OangsUy1qIQciHf15w;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;1&lt;/span&gt;&lt;/span&gt; to 26 years, some of which include options to extend leases. The exercise of lease renewal options is at the Company&#x2019;s sole discretion and the Company&#x2019;s lease ROU assets and liabilities reflect only the options the Company is reasonably certain that it will exercise. We do not have leases with residual value guarantees or similar covenants.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Operating lease costs for the&#160;years ended October&#160;31, 2021 and 2020 was $1.5 million. As of October&#160;31, 2021, the weighted average remaining lease term (in&#160;years) was approximately 20 years and the weighted average discount rate was 8.15%. Lease payments made during the&#160;years ended October&#160;31, 2021 and 2020 totaled $1.2 million and $1.0 million, respectively.&lt;/p&gt;&lt;p style="font-family:'Times New

Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"&gt;On August 25, 2021, an indirect wholly-owned subsidiary of the Company, San Bernardino Fuel Cell, LLC (&#x201c;SBFC&#x201d;), entered into a Purchase and Sale Agreement (the &#x201c;San Bernardino Purchase Agreement&#x201d;) and an Equipment Lease Agreement (the &#x201c;San Bernardino Lease&#x201d;) with Crestmark Equipment Finance (&#x201c;Crestmark&#x201d;). Under these agreements, SBFC sold the 1.4 MW biogas fueled fuel cell power plant (the &#x201c;San Bernardino Plant&#x201d;) located at the San Bernardino wastewater treatment plant in San Bernardino, California to Crestmark for a purchase price of $10.2 million and then leased the San Bernardino Plant back from Crestmark. SBFC sells the power produced by the San Bernardino Plant to a third party under a twenty-year PPA (the &#x201c;San Bernardino PPA&#x201d;). &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The San Bernardino Lease has an initial term of ten years but may be extended at the option of SBFC. An initial rental down payment and one quarter&#x2019;s rent totaling $2.2 million was paid using the proceeds from the sale of the San Bernardino Plant. Lease payments are expected to be funded with proceeds from the sale of power under the San Bernardino PPA on a quarterly basis. As a result of the sale-leaseback transaction, the remaining lease payments due over the term of the San Bernardino Lease were approximately $5.3 million immediately following the transaction and as of October&#160;31, 2021.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"&gt;Reserves covering debt service and future module replacement totaling $2.5 million were also deducted from the proceeds from the sale of the San Bernardino Plant and will be classified as restricted cash of the Company until such time as it meets its performance obligations (such as servicing the San Bernardino Plant and providing module exchanges) under the Long Term Service Agreement for the San Bernardino Plant. The Company&#x2019;s net unrestricted cash proceeds from the transaction totaled approximately $5.3 million, which is the purchase price less the initial rent payments, debt and module reserves, and taxes and transaction fees. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;In addition, SBFC and Crestmark entered into an Assignment Agreement on August 25, 2021 (the &#x201c;San Bernardino Assignment Agreement&#x201d;) and FuelCell Finance (a wholly-owned subsidiary of the Company and the direct parent of SBFC) and Crestmark entered into a Pledge Agreement on August 25, 2021 (the &#x201c;San Bernardino Pledge Agreement&#x201d;) pursuant to which agreements collateral was provided to Crestmark to secure SBFC&#x2019;s obligations under the San Bernardino Lease which includes a security interest in (i) certain agreements relating to the sale-leaseback transaction, (ii) the revenues with respect to the San Bernardino Plant, (iii) a cash module replacement reserve for the San Bernardino Plant, and (iv) FuelCell Finance&#x2019;s equity interest in SBFC. SBFC and the Company also entered into a Technology License and Access Agreement with Crestmark on August 25, 2021, which provides Crestmark with certain intellectual property license rights to have access to the Company&#x2019;s proprietary fuel cell technology, but only for the purpose of maintaining and servicing the San Bernardino Plant in certain circumstances in which the Company is not satisfying its obligations under its service agreement with regard to the maintenance and servicing of the San Bernardino Plant.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Pursuant to the San Bernardino Lease, SBFC has an obligation to indemnify Crestmark for the amount of any actual reduction in the U.S. investment tax credit (&#x201c;ITC&#x201d;) anticipated to be realized by Crestmark in connection with this sale-leaseback transaction. Such obligation would arise as a result of reductions to the value of the underlying fuel cell project as assessed by the U.S. Internal Revenue Service (&#x201c;IRS&#x201d;). The Company does not believe that any such obligation is probable based on the facts known as of October 31, 2021. The maximum potential future payments that SBFC could be required to make as a result of this obligation would depend on the difference between the fair value of the fuel cell project sold or financed and the value the IRS would determine as the fair value of the project for purposes of claiming the ITC. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;The value of the ITC in the sale-leaseback agreements is based on guidelines provided by regulations from the IRS.

Under these agreements, CCFC2 sold the 2.8 MW biogas fueled fuel cell power plant (the &#x201c;Tulare Plant&#x201d;) located at the Tulare wastewater treatment plant in Tulare, California to Crestmark for a purchase price of $14.4 million and then leased the Tulare Plant back from Crestmark. CCFC2 sells the power produced by the Tulare Plant to a third party under a twenty-year PPA (the &#x201c;Tulare PPA&#x201d;). The Tulare Lease includes an end of term option for CCFC2 to repurchase the transferred assets. The repurchase clause precluded sale accounting since there are no alternative assets substantially the same as the transferred assets readily available in the marketplace. As such, the transaction is a failed sale-leaseback transaction that is accounted for as a financing transaction.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="margin-bottom:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Tulare Lease has an initial term of ten years but may be extended at the option of CCFC2. An initial rental down payment and one&#160;month&#x2019;s rent totaling $2.9 million was paid using the proceeds from the sale of the Tulare Plant. Lease payments are due on a&#160;monthly basis in the amount of $0.1 million. Lease payments are expected to be funded with proceeds from the sale of power under the Tulare PPA. As a result of the sale-leaseback transaction, the remaining lease payments due over the term of the Tulare Lease were approximately $9.3 million immediately following the transaction and $7.7 million and $8.6 million as of October&#160;31, 2021 and 2020, respectively.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;CCFC2 and Crestmark entered into an Assignment Agreement on February&#160;11, 2020 (the &#x201c;Tulare Assignment Agreement&#x201d;) and FuelCell Finance, a wholly-owned subsidiary of the Company and the direct parent of CCFC2, and Crestmark entered into a Pledge Agreement on February&#160;11, 2020 (the &#x201c;Tulare Pledge Agreement&#x201d;) pursuant to which agreements collateral was provided to Crestmark to secure CCFC2&#x2019;s obligations under the Tulare Lease which includes a security interest in (i)&#160;certain agreements relating to the sale-leaseback transaction, (ii)&#160;the revenues with respect to the Tulare Plant, (iii)&#160;two fuel cell replacement modules for the Tulare Plant, and (iv)&#160;FuelCell Finance&#x2019;s equity interest in CCFC2.

with Orion Energy Partners Investment Agent, LLC, as Administrative Agent and Collateral Agent (the &#x201c;Orion Agent&#x201d;), and certain lenders affiliated with the Orion Agent for a $200.0 million senior secured credit facility (the &#x201c;Orion Facility&#x201d;), structured as a delayed draw term loan to be provided by the lenders primarily to fund certain of the Company&#x2019;s construction and related costs for fuel cell projects meeting the requirements of the Orion Facility. Under the Orion Credit Agreement, each lender funded its commitments less 2.50% of the aggregate principal amount of the loans funded by such lender (the &#x201c;Loan Discount&#x201d;).&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On October&#160;31, 2019, the Company drew down $14.5 million (the &#x201c;Initial Funding&#x201d;) and received $14.1 million, after taking into account a Loan Discount of $0.4 million. On October&#160;31, 2019, in connection with the Initial Funding, the Company issued warrants to the lenders under the Orion Credit Agreement to purchase up to a total of 6,000,000 shares of the Company&#x2019;s common stock, at an exercise price of $0.310 per share (the &#x201c;Initial Funding Warrants&#x201d;).&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;On November&#160;22, 2019, a second draw (the &#x201c;Second Funding&#x201d;) of $65.5 million, funded by&#160;Orion Energy Credit Opportunities Fund II,&#160;L.P., Orion Energy Credit Opportunities Fund II GPFA,&#160;L.P., Orion Energy Credit Opportunities &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Fund II PV,&#160;L.P., and Orion Energy Credit Opportunities FuelCell Co-Invest,&#160;L.P.

The Company received $63.9 million in the Second Funding after taking into account a Loan Discount of $1.6 million as described above. Also in conjunction with the Second Funding, the Company issued to the lenders warrants to purchase up to a total of 14.0 million shares of the Company&#x2019;s common stock, with an initial exercise price with respect to 8.0 million of such shares of $0.242 per share and with an initial exercise price with respect to 6.0 million of such shares of $0.620 per share (the &#x201c;Second Funding Warrants&#x201d;).&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Under the Orion Credit Agreement, cash interest of 9.9% per annum was paid quarterly. In addition to the cash interest, payment-in-kind interest of 2.05% per annum accrued which was added to the outstanding principal balance of the Orion Facility but was paid quarterly in cash to the extent of available cash after payment of the Company&#x2019;s operating expenses and the funding of certain reserves for the payment of outstanding indebtedness to the State of Connecticut and Connecticut Green Bank.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Outstanding principal under the Orion Facility was to be amortized on a straight-line basis over a seven-year term with the initial payment due 21 business&#160;days after the end of the first quarter of fiscal&#160;year 2021. The maturity date of the Orion Facility was October&#160;31, 2027. The Orion Facility contained an administrative fee of $0.1 million per&#160;year paid on a quarterly basis and also included a prepayment premium of up to 35%.

Upon entering into the secondary facility loan commitment, the Company owed the lenders under the Orion Credit Agreement an option premium of $1.0 million. The Company paid the $1.0 million option premium during the&#160;year ended October&#160;31, 2020 and recorded the amount as interest expense.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On November&#160;30, 2020, the Company, its subsidiary guarantors, and the Orion Agent entered into a payoff letter with respect to the Orion Credit Agreement (the &#x201c;Orion Payoff Letter&#x201d;). Pursuant to the Orion Payoff Letter, on December&#160;7, 2020, the Company paid a total of $87.3 million to the Orion Agent, representing the outstanding principal, accrued but unpaid interest, prepayment premium, fees, costs and other expenses due and owing under the Orion Facility and the Orion Credit Agreement and related loan documents, in full repayment of the Company&#x2019;s outstanding indebtedness under the Orion Facility and the Orion Credit Agreement and related loan documents. In accordance with the Orion Payoff Letter, the aggregate prepayment premium set forth in the Orion Credit Agreement was reduced from approximately $14.9 million to $4.0 million and the Orion Agent, on behalf of itself and the lenders, agreed that any portion of the prepayment premium that would otherwise be required to be paid pursuant to the Orion Credit Agreement in excess of $4.0 million was waived by the Orion Agent and the lenders. The Company expensed the remaining deferred finance costs and debt discount of $7.1 million. The Company has classified the $4.0 million prepayment premium and the deferred finance costs and debt discount expense as Loss on extinguishment of debt and financing obligation on the Consolidated Statements of Operations and Comprehensive Loss.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Concurrently with the Orion Agent&#x2019;s receipt of full payment pursuant to the Orion Payoff Letter, the Orion Agent released all of the collateral from the liens granted under the security documents associated with the Orion Facility (which included the release of $11.2 million of restricted cash to the Company, which became unrestricted cash), and the Company and its subsidiaries were unconditionally released from their respective obligations under the Orion Credit Agreement (and related loan documents) and the Orion Facility without further action. With the termination of the Orion Facility and the Orion Credit Agreement and related loan documents, the lenders no longer have the right to appoint representatives to attend the Company&#x2019;s Board of Director meetings as observers.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Connecticut Green Bank Loans&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;As of October&#160;31, 2019, the Company had a long-term loan agreement with the Connecticut Green Bank, providing the Company with a loan of $1.8 million (the &#x201c;Green Bank Loan Agreement&#x201d;). On and effective as of December&#160;19, 2019, the Company and Connecticut Green Bank entered into an amendment to the Green Bank Loan Agreement (the &#x201c;Green Bank Amendment&#x201d;). Upon the execution of the Green Bank Amendment on December&#160;19, 2019, Connecticut Green Bank made an additional loan to the Company in the aggregate principal amount of $3.0 million (the &#x201c;December&#160;2019 Loan&#x201d;), which was to be used (i)&#160;first, to pay closing fees related to the May&#160;9, 2019 acquisition of the Bridgeport Fuel Cell Project and the Subordinated Credit Agreement (as defined below), other fees and interest, and (ii)&#160;thereafter, for general corporate purposes.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Green Bank Amendment provides that, until such time as the loan (which includes both the outstanding principal balance of the original loan under the Green Bank Loan Agreement and the outstanding principal amount of the December&#160;2019 Loan) has been repaid in its entirety, interest on the outstanding balance of the loan shall accrue at a rate of 8% per annum, payable by the Company on a&#160;monthly basis in arrears. Interest payments made by the Company after the date of the Green Bank Amendment are to be applied first to interest that has accrued on the outstanding principal balance of the original loan under the Green Bank Loan Agreement and then to interest that has accrued on the December&#160;2019 Loan.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Green Bank Amendment also modifies the repayment and mandatory prepayment terms and extends the maturity date set forth in the original Green Bank Loan Agreement. Under the Green Bank Amendment, to the extent that excess cash flow reserve funds under the BFC Credit Agreement (as defined below) are eligible for disbursement to Bridgeport Fuel Cell, LLC pursuant to Section&#160;6.23(c)&#160;of the BFC Credit Agreement, such funds are to be paid to Connecticut Green Bank until the loans are repaid in full. The Green Bank Amendment further provides that any unpaid balance of the loan and all other obligations due under the Green Bank Loan Agreement will be due and payable on May&#160;9, 2026. Finally, with respect to mandatory prepayments, the Green Bank Amendment provides that, when the Company has closed on the subordinated project term loan pursuant to the Commitment Letter, dated February&#160;6, 2019, issued by Connecticut Green Bank to &lt;span style="background:#ffffff;"&gt;Groton Station Fuel Cell, LLC (&#x201c;Groton Fuel Cell&#x201d;)&lt;/span&gt; to provide a subordinated project term loan to Groton Fuel Cell in the amount of $5.0 million, the Company will be required to prepay to Connecticut Green Bank the lesser of any then outstanding amount of the December&#160;2019 Loan and the amount of the subordinated project term loan actually advanced by Connecticut Green Bank. The balance under the original Green Bank Loan Agreement and the December&#160;2019 Loan as of October&#160;31, 2021 was $4.8 million.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Bridgeport Fuel Cell Project Loans&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On May&#160;9, 2019, in connection with the closing of the purchase of the membership interests of Bridgeport Fuel Cell, LLC (&#x201c;BFC&#x201d;) (and the 14.9 MW Bridgeport Fuel Cell Project), BFC entered into a subordinated credit agreement with the Connecticut Green Bank whereby Connecticut Green Bank provided financing in the amount of $6.0 million (the &#x201c;Subordinated Credit Agreement&#x201d;). This $6.0 million consisted of $1.8 million in incremental funding that was received by BFC and $4.2 million of funding previously received by FuelCell Energy,&#160;Inc. with respect to which BFC became the primary obligor. As security for the Subordinated Credit Agreement, Connecticut Green Bank received a perfected lien, subordinated and second in priority to the liens securing the $25.0 million loaned under the BFC Credit Agreement (as defined below), in all of the same collateral securing the BFC Credit Agreement. The interest rate under the Subordinated Credit Agreement is 8% per annum. Principal and interest are due&#160;monthly in amounts sufficient to fully amortize the loan over an 84-month period ending in May&#160;2026. The Subordinated Credit Agreement contains a debt coverage ratio which is required to be maintained and may not be less than 1.10 as of the end of each fiscal quarter, beginning with the quarter ended July&#160;31, 2020. The balance under the Subordinated Credit Agreement as of October&#160;31, 2021 was $4.3 million.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On May&#160;9, 2019, in connection with the closing of the purchase of the Bridgeport Fuel Cell Project, BFC &#160;entered into a Credit Agreement with Liberty Bank, as administrative agent and co-lead arranger, and Fifth Third Bank as co-lead arranger and interest rate swap hedger (the &#x201c;BFC Credit Agreement&#x201d;), whereby (i)&#160;Fifth Third Bank provided financing in the amount of $12.5 million towards the purchase price for the BFC acquisition; and (ii)&#160;Liberty Bank provided financing in the amount of $12.5 million towards the purchase price for the BFC acquisition. As security for the BFC Credit Agreement, Liberty Bank and Fifth Third Bank were granted a first priority lien in (i)&#160;all assets of BFC, including BFC&#x2019;s cash accounts, fuel cells, and all other personal property, as well as third party contracts including the Energy Purchase Agreement between BFC and Connecticut Light and Power Company dated July&#160;10, 2009, as amended; (ii)&#160;certain fuel cell modules that are intended to be used to replace the Bridgeport Fuel Cell Project&#x2019;s fuel cell modules as part of routine operation and maintenance; and (iii)&#160;FuelCell Finance&#x2019;s (a wholly-owned subsidiary of the Company and the direct parent of BFC) ownership interest in BFC. The maturity date under the BFC Credit Agreement is May&#160;9, 2025.&#160;Monthly principal and interest are to be paid in arrears in an amount sufficient to fully amortize the term loan over a 72-month period. BFC has the right to make additional principal payments or pay the balance due under the BFC Credit Agreement in full, provided that it pays any associated breakage fees with regard to the interest rate swap agreements fixing the interest rate. The interest rate under the BFC Credit Agreement fluctuates&#160;monthly at the 30-day LIBOR rate plus 275 basis points.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;An interest rate swap agreement was required to be entered into with Fifth Third Bank in connection with the BFC Credit Agreement to protect against movements in the floating LIBOR index. Accordingly, on May&#160;16, 2019, an interest rate swap agreement (the &#x201c;Swap Agreement&#x201d;) was entered into with Fifth Third Bank in connection with the BFC Credit Agreement for the term of the loan. The net interest rate across the BFC Credit Agreement and the swap transaction results in a fixed rate of 5.09%. The interest rate swap is adjusted to fair value on a quarterly basis. The estimated fair value is based on Level 2 inputs including primarily the forward LIBOR curve available to swap dealers. The valuation methodology involves comparison of (i)&#160;the sum of the present value of all&#160;monthly variable rate payments based on a reset rate using the forward LIBOR curve and (ii)&#160;the sum of the present value of all&#160;monthly fixed rate payments on the notional amount, which is equivalent to the outstanding principal amount of the loans. The fair value adjustments for the&#160;years ended October&#160;31, 2021, 2020 and 2019 resulted in a $0.5 million gain, a $0.3 million gain and a $0.6 million charge, respectively. The fair value of the interest rate swap liability as of October&#160;31, 2021 and 2020 was $0.5 million and $0.9 million, respectively.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The BFC Credit Agreement requires BFC to maintain a debt service reserve. Each of Liberty Bank and Fifth Third Bank also has an operation and module replacement reserve (&#x201c;O&amp;amp;M Reserve&#x201d;) under the BFC Credit Agreement. BFC is required to deposit $0.1 million per&#160;month into each O&amp;amp;M Reserve for the first five&#160;years of the BFC Credit Agreement, with such funds to be released at the sole discretion of Liberty Bank and Fifth Third Bank, as applicable. BFC is also required to maintain excess cash flow reserve accounts at each of Liberty Bank and Fifth Third Bank. Excess cash flow consists of cash generated by BFC from the Bridgeport Fuel Cell Project after payment of all expenses (including after payment of intercompany service fees to the Company), debt service to Liberty Bank and Fifth Third Bank, the funding of all required reserves, and payments to Connecticut Green Bank for the subordinated facility. BFC is also required to maintain a debt service coverage ratio of not less than 1.20, measured for the trailing&#160;year based on fiscal quarters beginning with the quarter ended July&#160;31, 2020. The Company has certain quarterly and annual financial reporting requirements under the BFC Credit Agreement. The annual financial statements to be provided pursuant to such requirements are to be audited and accompanied by a report of an independent certified public accountant, which report shall not include a &#x201c;going concern&#x201d; matter of emphasis or any qualification as to the scope of such audit.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Finance obligations for sale leaseback agreements&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Several of the Company&#x2019;s project subsidiaries previously entered into sale-leaseback agreements with PNC for commissioned projects where the Company had entered into a PPA with the site host/end-user of produced power, and CCFC2 and SBFC entered into sale-leaseback transactions with Crestmark on February&#160;11, 2020 and August 25, 2021, respectively (refer to Note. 13. &#x201c;Leases&#x201d; for additional information). The Company did not recognize as revenue any of the proceeds received from the lessor that contractually constitute payments to acquire the assets subject to these arrangements. Instead, the sale proceeds received were accounted for as financing obligations. The outstanding financing obligation balance as of October&#160;31, 2021 was $56.5 million as compared to $49.3 million as of October&#160;31, 2020. This change reflects the recording of the finance obligation with Crestmark for the San Bernardino Plant sale leaseback transaction and the recognition of interest expense, offset by lease payments. The outstanding financing obligation for the remaining leases includes $34.8 million in excess of future required payments, not including amounts for the potential repurchase price of the project assets which is based on fair value. The sale-leaseback arrangements with PNC allow the &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Company to repurchase the project assets at fair market value and the sale-leaseback arrangements with Crestmark include a purchase right for the greater of fair market value or 31% of the purchase price.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;State of Connecticut Loan&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;In October&#160;2015, the Company closed on a definitive Assistance Agreement with the State of Connecticut (the &#x201c;Assistance Agreement&#x201d;) and received a disbursement of $10.0 million, which was used for the first phase of the expansion of the Company&#x2019;s Torrington, Connecticut manufacturing facility. In conjunction with this financing, the Company entered into a $10.0 million promissory note and related security agreements securing the loan with equipment liens and a mortgage on its Danbury, Connecticut location. Interest accrues at a fixed interest rate of 2.0%, and the loan is repayable over 15 years from the date of the first advance, which occurred in October&#160;of 2015. Principal payments were deferred for four years from disbursement and began on December&#160;1, 2019. Under the Assistance Agreement, the Company was eligible for up to $5.0 million in loan forgiveness if the Company created 165 full-time positions and retained 538 full-time positions for two consecutive&#160;years (the &#x201c;Employment Obligation&#x201d;) as measured on October&#160;28, 2017 (the &#x201c;Target Date&#x201d;). The Assistance Agreement was subsequently amended in April&#160;2017 to extend the Target Date by two&#160;years to October&#160;28, 2019.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;In January&#160;2019, the Company and the State of Connecticut entered into a Second Amendment to the Assistance Agreement (the &#x201c;Second Amendment&#x201d;). The Second Amendment extended the Target Date to October&#160;31, 2022 and amended the Employment Obligation to require the Company to continuously maintain a minimum of 538 full-time positions for 24 consecutive&#160;months. If the Company meets the Employment Obligation, as modified by the Second Amendment, and creates an additional 91 full-time positions, the Company may receive a credit in the amount of $2.0 million to be applied against the outstanding balance of the loan. However, based on the Company&#x2019;s current headcount and plans for fiscal&#160;year 2022 and beyond, it will not meet this requirement or receive this credit. A job audit will be performed within 90 days of the Target Date. If the Company does not meet the Employment Obligation, then an accelerated payment penalty will be assessed at a rate of $18,587.36 multiplied by the number of employees below the number of employees required by the Employment Obligation. Such penalty is immediately payable and will be applied first to accelerate the payment of any outstanding fees or interest due and then to accelerate the payment of outstanding principal.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;In April&#160;of 2020, as a result of the COVID-19 pandemic, the State of Connecticut agreed to defer three months of principal and interest payments under the Assistance Agreement, beginning with the May&#160;2020 payment. These deferred payments will be added at the end of the loan, thus extending out the maturity date by three&#160;months.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Liberty Bank Promissory Note&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On April&#160;20, 2020, the Company entered into &lt;span style="background:#ffffff;"&gt;a Paycheck Protection Program Promissory Note, dated April 16, 2020 (the &#x201c;PPP Note&#x201d;)&lt;/span&gt;, evidencing a loan to the Company from Liberty Bank, under the CARES Act, administered by the Small Business Administration (&#x201c;SBA&#x201d;). Pursuant to the PPP Note, the Company received total proceeds of approximately $6.5 million on April&#160;24, 2020 (the &#x201c;PPP Loan&#x201d;).&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;padding-bottom:12pt;text-align:justify;margin:0pt;"&gt;The PPP Note&#160;was scheduled to mature on April&#160;16, 2022, had a 1.00% per annum interest rate, and was subject to the terms and conditions applicable to loans administered by the SBA under the CARES Act, as amended by the Paycheck Protection Program Flexibility Act of 2020.&#160;Monthly principal and interest payments, less the amount of any potential forgiveness, commenced on November&#160;16, 2020. The Company did not provide any collateral or guarantees for the PPP Note, nor did the Company pay any facility charge to obtain the PPP Note.

      id="Narr_VAuzjJKv_kGSDMiJi5AwBw">On May&#160;9, 2019, in connection with the closing of the purchase of the membership interests of Bridgeport Fuel Cell, LLC (&#x201c;BFC&#x201d;) (and the 14.9 MW Bridgeport Fuel Cell Project), BFC entered into a subordinated credit agreement with the Connecticut Green Bank whereby Connecticut Green Bank provided financing in the amount of $6.0 million (the &#x201c;Subordinated Credit Agreement&#x201d;). This $6.0 million consisted of $1.8 million in incremental funding that was received by BFC and $4.2 million of funding previously received by FuelCell Energy,&#160;Inc. with respect to which BFC became the primary obligor. As security for the Subordinated Credit Agreement, Connecticut Green Bank received a perfected lien, subordinated and second in priority to the liens securing the $25.0 million loaned under the BFC Credit Agreement (as defined below), in all of the same collateral securing the BFC Credit Agreement. The interest rate under the Subordinated Credit Agreement is 8% per annum. Principal and interest are due&#160;monthly in amounts sufficient to fully amortize the loan over an 84-month period ending in May&#160;2026. The Subordinated Credit Agreement contains a debt coverage ratio which is required to be maintained and may not be less than 1.10 as of the end of each fiscal quarter, beginning with the quarter ended July&#160;31, 2020. The balance under the Subordinated Credit Agreement as of October&#160;31, 2021 was $4.3 million.</us-gaap:DebtInstrumentCovenantDescription>

In addition, under the Orion Credit Agreement, on the date of the Second Funding (November&#160;22, 2019), the Company issued warrants to the lenders under the Orion Credit Agreement to purchase up to a total of 14,000,000 shares of the Company&#x2019;s common stock, with an exercise price with respect to 8,000,000 of such shares of $0.242 per share and with an exercise price with respect to 6,000,000 of such shares of $0.620 per share (the &#x201c;Second Funding Warrants&#x201d;, and together with the Initial Funding Warrants, the &#x201c;Orion Warrants&#x201d;). &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company accounted for the Initial Funding Warrants as a liability since there was a change of control provision in the Initial Funding Warrants regarding the composition of the board of directors and, as such, the Company could have been required to repurchase the Initial Funding Warrants upon such change in control and therefore equity classification was precluded. The Company accounted for the Second Funding Warrants under ASC 815, &lt;i style="font-style:italic;"&gt;Derivatives and Hedging &lt;/i&gt;(&#x201c;ASC 815&#x201d;) since the Second Funding Warrants were considered contingent vesting warrants and therefore were considered to be an outstanding liability. Since the probability of vesting for the Second Funding Warrants was deemed to be 100% as there was no vesting period in the warrants, there was no impact on the valuation. The Second Funding Warrants were accounted for as a liability since the Company might have been required to pay the holder under the same change of control provision as the Initial Funding Warrants and such event was outside the Company&#x2019;s control and therefore equity classification was precluded.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;As of October&#160;31, 2019, the estimated fair value of the Orion Warrants was based on a Black-Scholes model using Level 2 inputs, including volatility of 96%, a risk free rate of 1.63%, the Company&#x2019;s common stock price as of October&#160;31, 2019 of $0.24 per share and the term of 8 years which resulted in a total value of $3.9 million.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.09;text-align:justify;margin:10pt 0pt 0pt 0pt;"&gt;During the three&#160;months ended January&#160;31, 2020, the lenders exercised, on a cashless basis, Orion Warrants representing the right to purchase 12,000,000 shares of the Company&#x2019;s common stock. Because these Orion Warrants were exercised on a cashless basis, the Company issued in the aggregate 9,396,320 shares of the Company&#x2019;s common stock. The Orion Warrants that were converted were remeasured to fair value immediately preceding the conversion based upon volatility of 103.7%, a risk free rate of 1.81% and the Company&#x2019;s common stock price of $2.29 on January&#160;8, 2020, which resulted in a $23.7 million charge for the three&#160;months ended January&#160;31, 2020. The revised estimated fair value of the converted Orion Warrants as of the date of conversion of $26.0 million was reclassified to Additional paid in capital. The remaining Orion Warrants as of January&#160;31, 2020 were remeasured to estimated fair value based upon a volatility of 104.9%, a risk free rate of 1.45% and the Company&#x2019;s common stock price at January&#160;31, 2020 of $1.59 per share, which resulted in a charge for the three&#160;months ended January&#160;31, 2020 of $10.5 million. &#160;The Company remeasured the remaining Orion Warrants at October 31, 2020 based upon a volatility of 114.15%, a risk free rate of 0.64% and the Company&#x2019;s common stock price of $2.00 per share, which resulted in a charge of $0.2 million. &#160;The estimated fair value of the remaining Orion &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.09;text-align:justify;margin:0pt;"&gt;Warrants outstanding was $5.2 million as of October 31, 2020 and is classified as Long-term debt and other liabilities on the Company&#x2019;s Consolidated Balance Sheets.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.09;text-align:justify;margin:10pt 0pt 0pt 0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On December&#160;7, 2020, all remaining Orion Warrants were exercised to purchase a total of 2,700,000 shares of the Company&#x2019;s common stock for an aggregate exercise price of approximately $0.6 million (or $0.242 per share). The Orion Warrants that were converted on December&#160;7, 2020 were remeasured to fair value immediately preceding the conversion based upon volatility of 117.02%, a risk free rate of 0.70% and the Company&#x2019;s common stock price of $7.95 on December&#160;4, 2020, which resulted in a $16.0 million charge for the three&#160;months ended January&#160;31, 2021. The estimated fair value of the converted Orion Warrants as of the December 7, 2020 date of conversion of $21.2 million was reclassified to Additional paid-in capital.&lt;/p&gt;&lt;p

Redeemable Preferred Stock&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company is authorized to issue up to 250,000 shares of preferred stock, par value $0.01 per share, in one or more series, of which 105,875 shares were designated as 5% Series&#160;B Cumulative Convertible Perpetual Preferred Stock (referred to herein as Series&#160;B Preferred Stock) in March&#160;2005. Pursuant to our Certificate of Incorporation, as amended, our undesignated shares of preferred stock now include all of our shares of preferred stock that were previously designated as Series&#160;C Convertible Preferred Stock (&#x201c;Series C Preferred Stock&#x201d;) and Series&#160;D Convertible Preferred Stock (&#x201c;Series D Preferred Stock&#x201d;), as all such shares have been retired and therefore have the status of authorized and unissued shares of preferred stock undesignated as to series. In addition to the above, a subsidiary of the Company had authorized and issued preferred stock as of October&#160;31, 2021, as described below.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"&gt;Series&#160;D Preferred Stock&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;In August&#160;2018, the Company issued 30,680 shares of Series&#160;D Preferred Stock, which were initially convertible into 1,852,657 shares of the Company&#x2019;s common stock at an initial conversion price of $16.56 per share (&#x201c;Series&#160;D Conversion Price&#x201d;), subject to certain adjustments.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The net proceeds to the Company from the sale of the Series&#160;D Preferred Stock, after deducting the underwriting discounts and commissions and the offering expenses payable by the Company, were $25.3 million.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;During the fiscal&#160;year ended October&#160;31, 2019, holders of the Series&#160;D Preferred Stock converted all 30,680 shares of Series&#160;D Preferred Stock (the &#x201c;Series&#160;D Preferred Shares&#x201d;) into 62,040,496 shares of common stock, resulting in a reduction of $31.2 million to the carrying value being recorded to equity. Conversions in which the conversion price was below the fixed conversion price (the initial conversion price of the Series&#160;D Preferred Stock) resulted in a variable number of shares being issued to settle the conversion amounts and were treated as a partial redemption of the Series&#160;D Preferred Shares. Conversions during the&#160;year ended October&#160;31, 2019 that were settled in a variable number of shares and treated as redemptions resulted in deemed dividends of $6.0 million. The deemed dividends represent the difference between the fair value of the shares of common stock issued to settle the conversion amounts and the carrying value of the Series&#160;D Preferred Shares.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Series&#160;D Preferred Stock redemption accretion of $3.8 million for the fiscal&#160;year ended October&#160;31, 2019 reflects the accretion of the difference between the carrying value and the amount that would have been redeemed if stockholder approval had not been obtained for the issuance of common stock equal to 20.0% or more of the Company&#x2019;s outstanding voting stock prior to the issuance of the Series&#160;D Preferred Stock. Prior to receiving stockholder approval of the issuance of 20.0% or more of the Company&#x2019;s outstanding voting stock prior to the issuance of the Series&#160;D Preferred Stock, the holders were prohibited from converting Series&#160;D Preferred Shares into shares of common stock if such conversion would have caused the Company to issue pursuant to the terms of the Series&#160;D Preferred Stock a number of shares in excess of the maximum number of shares permitted to be issued thereunder without breaching the Company&#x2019;s obligations under the rules&#160;or regulations of the Nasdaq Global Market. The Company received stockholder approval of such issuance at the annual meeting of the Company&#x2019;s stockholders on April&#160;4, 2019.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;During the week of June&#160;10, 2019, the holders of the Series&#160;D Preferred Stock asserted that certain triggering events had occurred under the Certificate of Designations, Preferences and Rights of the Series&#160;D Preferred Stock of the Company (the &#x201c;Series&#160;D Certificate of Designation&#x201d;) and indicated their intent to exercise their rights to convert certain of their shares at a reduced conversion price. While the Company did not agree with the basis for their assertions or their characterization of such events, there were provisions under the Series&#160;D Certificate of Designation which could be interpreted as giving the holders the right to demand such conversion at a reduced conversion price. Accordingly, during the period beginning on June&#160;11, 2019 and ending on July&#160;3, 2019, the Company effected conversions at reduced conversion prices ranging from $0.14 to $0.61.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"&gt;Series&#160;C Preferred Stock&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;During the fiscal&#160;year ended October&#160;31, 2017, the Company issued 33,500 shares of Series&#160;C Preferred Stock (the &#x201c;Series C Preferred Shares&#x201d;) for net proceeds of $27.9 million.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;As of October&#160;31, 2018, there were 8,992 shares of Series&#160;C Preferred Stock issued and &lt;span style="-sec-ix-hidden:Hidden_LOfb7tf2i0yNkywastuWtA;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;outstanding&lt;/span&gt;&lt;/span&gt;, with a carrying value of $7.5 million.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On February&#160;21, 2019, the Company entered into a Waiver Agreement (the &#x201c;Waiver Agreement&#x201d;) with the holder of the Series&#160;C Preferred Stock (such holder, the &#x201c;Series&#160;C Holder&#x201d;). Under the Waiver Agreement, the Series&#160;C Holder waived any equity conditions failures that may have occurred under the Certificate of Designations, Preferences and Rights of the Series&#160;C Preferred Stock of the Company (the &#x201c;Series&#160;C Certificate of Designations&#x201d;). The Series&#160;C Holder further waived any triggering event occurring after the date of the Waiver Agreement, as well as its right to demand, require or otherwise receive cash payments under the Series&#160;C Certificate of Designations, which waiver would have terminated upon the occurrence of certain key triggering events (failure to provide freely tradable shares, suspension from trading on the Nasdaq Global Market or another eligible market, or failure to convert or deliver shares under certain circumstances), the occurrence of a fundamental transaction, a breach of the Waiver Agreement, or the occurrence of a bankruptcy triggering event. In addition, the Company agreed in the Waiver Agreement, pursuant to Section&#160;8(d)&#160;of the Series&#160;C Certificate of Designations, to adjust the conversion price of the Series&#160;C Preferred Stock in connection with future conversions, such that, when the Series&#160;C Holder converted its Series&#160;C Preferred Stock into common stock, it would receive approximately 25% more shares than it would have received upon conversion prior to the execution of the Waiver Agreement. Under the Waiver Agreement, the conversion price of the Series&#160;C Preferred Stock was stated to be the lowest of (i)&#160;$4.45, (ii)&#160;85% of the lowest closing bid price of the Company&#x2019;s common stock during the period beginning on and including the fifth trading day prior to the date on which the applicable conversion notice was delivered to the Company and ending on and including the date on which the applicable conversion notice was delivered to the Company, and (iii)&#160;85% of the quotient of (A)&#160;the sum of the five lowest volume weighted average prices of the Company&#x2019;s common stock during the 20 consecutive trading day period ending on and including the trading day immediately preceding the applicable conversion date divided by (B)&#160;five. To determine the number of shares of common stock to be issued upon conversion, 125% of the value of the Series&#160;C Preferred Shares being converted was divided by the applicable conversion price. The parties further agreed to waive the installment payment/conversion provisions in Section&#160;9 of the Series&#160;C Certificate of Designations, which required installment conversions or payments to be made on the 1&lt;sup style="font-size:7.5pt;line-height:100%;top:0pt;vertical-align:top;"&gt;st&lt;/sup&gt; and 16&lt;sup style="font-size:7.5pt;line-height:100%;top:0pt;vertical-align:top;"&gt;th&lt;/sup&gt; of each&#160;month. Under the Waiver Agreement, conversions of Series&#160;C Preferred Stock were permitted to occur and did occur after the original March&#160;1, 2019 maturity date, and the Company further agreed to reserve specific numbers of shares for issuance to the Series&#160;C Holder and the holders of the Series&#160;D Preferred Stock until the Company effected a reverse stock split, which occurred on May&#160;8, 2019, or increased its authorized shares of common stock.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Waiver Agreement was treated for accounting purposes to be an extinguishment of the Series&#160;C Preferred Stock instrument as of February&#160;21, 2019. The Series&#160;C Preferred Stock remained classified in mezzanine equity, however, the carrying value was adjusted to reflect the estimated fair value of the post-modification Series&#160;C Preferred Shares which incorporated the new terms outlined in the Waiver Agreement. The valuation utilized a Binomial Lattice Model (&#x201c;Lattice Model&#x201d;) which is a commonly used methodology to value path-dependent options or stock units in order to capture their potential early conversion. The Lattice Model produces an estimated fair value based on changes in the underlying stock price over successive periods of time. The assumptions used in the model such as stock price, conversion price and conversion ratio were consistent with date of execution and terms in the Waiver Agreement. Other assumptions included the volatility of the Company&#x2019;s stock which was assumed to be 75% and a discount rate of 20% which was estimated based on various indices consistent with the Company&#x2019;s profile, venture capital rates of return and the Company&#x2019;s borrowing rate. The Lattice Model resulted in an estimated fair value as of February&#160;21, 2019 of $13.5 million whereby the Series&#160;C Preferred Stock carrying value was adjusted to this amount. As discussed below, a beneficial conversion feature was recorded during the three&#160;months ended January&#160;31, 2019 due to reductions in the conversion price. Upon extinguishment during the three&#160;months ended April&#160;30, 2019, the Company first allocated $6.6 million to the reacquisition of the embedded conversion option equal to the intrinsic value that was previously recognized during the three&#160;months ended January&#160;31, 2019 for the embedded conversion option. Because the remaining estimated fair value of the instrument on February&#160;21, 2019 was less than the carrying amount of the Series&#160;C Preferred Stock, the amount of the shortfall resulted in a decrease in loss available to common stockholders for purposes of computing loss per share of $0.6 million.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;In order to resolve different interpretations of the provisions of the Series&#160;C Certificate of Designations that governed adjustments to the conversion price in connection with sales of common stock under the Company&#x2019;s at-the-market stock sales plan below the initial conversion price of $22.08 and whether such sales constituted sales of variable priced securities under the Series&#160;C Certificate of Designations, the Company&#x2019;s Board of Directors agreed to reduce the conversion price of the Series&#160;C Preferred Shares from $22.08 to $18.00 effective August&#160;27, 2018 in exchange for a waiver of certain anti-dilution and price adjustment rights under the Series&#160;C Certificate of Designations for future at-the-market sales of common stock. The conversion price of the Series&#160;C Preferred Shares was adjusted again on December&#160;3, 2018 to $6.96, on December&#160;17, 2018 to $6.00 and on January&#160;2, 2019 to $5.16. During the period from February&#160;1, 2019 to May&#160;23, 2019, the conversion price was further adjusted to prices ranging from $4.45 to $1.27, the conversion price as of the last conversion, which occurred on May&#160;23, 2019. Conversions occurring during the fiscal&#160;year ended October&#160;31, 2019 resulted in a variable number of shares being issued to settle the conversion amounts and were treated as a partial redemption of the Series&#160;C Preferred Shares. Conversions during the&#160;year ended October&#160;31, 2019 that were settled in a variable number of shares and treated as partial redemptions resulted in deemed contributions of $1.5 million. The deemed contributions represent the difference between the fair value of the common shares issued to settle the conversion amounts and the carrying value of the Series&#160;C Preferred Shares. Additionally, as discussed in more detail above, the net loss attributable to common stockholders for the fiscal&#160;year ended October&#160;31, 2019 was impacted by a $0.5 million decrease in the loss resulting from accounting for the Waiver Agreement in February&#160;2019, which was recorded during the three&#160;months ended April&#160;30, 2019. The net loss attributable to common stockholders for the&#160;year ended October&#160;31, 2019 also includes the $8.6 million redemption value adjustment recorded during the three&#160;months ended January&#160;31, 2019.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Series&#160;C Preferred Shares were classified outside of permanent equity. The decline in the Company&#x2019;s stock price during the three&#160;months ended January&#160;31, 2019 and between January&#160;31, 2019 and the execution of the Waiver Agreement in February&#160;2019 resulted in equity conditions failures under the Series&#160;C Certificate of Designations, which were waived by the Series&#160;C Holder in the Waiver Agreement, as described above. Prior to the execution of such Waiver Agreement, the conversion price was adjusted in December&#160;2018 and January&#160;2019 as described above. This contingent beneficial conversion feature resulted in a $6.6 million reduction in the Series&#160;C Preferred Shares carrying value. Because the equity conditions failures were continuing as of January&#160;31, 2019 (prior to the execution of the Waiver Agreement), the Series&#160;C Preferred Shares were adjusted to 108% of stated redemption value as of January&#160;31, 2019 with a corresponding charge to common stockholders of $8.6 million.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;During the fiscal&#160;year ended October&#160;31, 2019, holders of the Series&#160;C Preferred Stock converted 8,992 Series&#160;C Preferred Shares into 3,914,218 shares of common stock, resulting in a reduction in carrying value of $15.5 million. Upon the conversion of the last outstanding Series&#160;C Preferred Shares on May&#160;23, 2019, there were no further Series&#160;C Preferred Shares outstanding.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;During the fiscal&#160;year ended October&#160;31, 2018, holders of the Series&#160;C Preferred Stock converted 24,308 Series&#160;C Preferred Shares into common shares through installment conversions resulting in a reduction of $20.2 million to the carrying value being recorded to equity. Installment conversions occurring prior to August&#160;27, 2018 in which the conversion price was &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;below the initial conversion price of $22.08 per share resulted in a variable number of shares being issued to settle the installment amount and were treated as a partial redemption of the Series&#160;C Preferred Shares. As discussed above, the Company&#x2019;s Board of Directors agreed to reduce the conversion price of the Series&#160;C Preferred Shares from $22.08 to $18.00 effective August&#160;27, 2018 in exchange for a waiver of certain anti-dilution and price adjustment rights under the Series&#160;C Certificate of Designations for future at-the-market sales. Installment conversions occurring between August&#160;27, 2018 and October&#160;31, 2018 in which the installment conversion price was below the adjusted conversion price of $18.00 per share resulted in a variable number of shares being issued to settle the installment amount and were treated as a partial redemption of the Series&#160;C Preferred Shares. Installment conversions during the&#160;year ended October&#160;31, 2018 that were settled in a variable number of shares and treated as partial redemptions resulted in deemed dividends of $9.6 million.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"&gt;Redeemable Series&#160;B Preferred Stock&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company has designated 105,875 shares of its authorized preferred stock as Series&#160;B Preferred Stock (liquidation preference $1,000.00 per share). As of October&#160;31, 2021 and 2020, there were 64,020 shares of Series&#160;B Preferred Stock issued and outstanding, with a carrying value of $59.9 million. The shares of Series&#160;B Preferred Stock and the shares of common stock issuable upon conversion of the shares of Series&#160;B Preferred Stock are covered by a registration rights agreement.

Dividends of $3.2 million and $4.8 million were paid in cash during the fiscal&#160;years ended October&#160;31, 2021 and 2020, respectively, and dividends of $1.6 million were paid in cash during the fiscal&#160;year ended October&#160;31, 2019.

Based on the dividend rate in effect on May&#160;15, 2019 and August&#160;15, 2019, the aggregate amount of such dividend payments would have been $1.6 million. Because such dividends were not paid on May&#160;15 or August&#160;15, under the terms of the Series&#160;B Certificate of Designation, the holders of shares of Series&#160;B Preferred Stock were entitled to receive, when, as and if, declared by the Board of Directors, dividends at a dividend rate per annum equal to the normal dividend rate of 5% plus an amount equal to the number of dividend periods for which the Company &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;failed to pay or set apart funds to pay dividends multiplied by 0.0625%, for each subsequent dividend period until the Company has paid or provided for the payment of all dividends on the shares of Series&#160;B Preferred Stock for all prior dividend periods.&#160;On October&#160;30, 2019, dividends were declared by the Board of Directors with respect to the May&#160;15, 2019 and August&#160;15, 2019 dividend payment dates as well as the November&#160;15, 2019 dividend payment date. A payment of $2.4 million made in the fiscal quarter ended January&#160;31, 2020 represented the dividends payable with respect to the May&#160;15, 2019 and August&#160;15, 2019 dividend dates and the dividends payable with respect to the November&#160;15, 2019 dividend date that were declared on October&#160;30, 2019.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;&lt;b style="font-weight:bold;"&gt;Liquidation.&lt;/b&gt; The holders of Series&#160;B Preferred Stock are entitled to receive, in the event that the Company is liquidated, dissolved or wound up, whether voluntarily or involuntarily, $1,000.00 per share plus all accumulated and unpaid dividends up to but excluding the date of such liquidation, dissolution, or winding up (the &#x201c;Liquidation Preference&#x201d;). Until the holders of Series&#160;B Preferred Stock receive the Liquidation Preference with respect to their shares of Series&#160;B Preferred Stock in full, no payment will be made on any junior shares, including shares of the Company&#x2019;s common stock. After the Liquidation Preference is paid in full, holders of the Series&#160;B Preferred Stock will not be entitled to receive any further distribution of the Company&#x2019;s assets. As of October&#160;31, 2021 and 2020, the issued and outstanding shares of Series&#160;B Preferred Stock had an aggregate Liquidation Preference of $64.0 million.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;&lt;b style="font-weight:bold;"&gt;Conversion Rights&lt;/b&gt;. Each share of Series&#160;B Preferred Stock may be converted at any time, at the option of the holder, into 0.591 shares of the Company&#x2019;s common stock (which is equivalent to an initial conversion price of $1,692.00 per share) plus cash in lieu of fractional shares. The conversion rate is subject to adjustment upon the occurrence of certain events, as described in the Series&#160;B Certificate of Designation. The conversion rate is not adjusted for accumulated and unpaid dividends. If converted, holders of Series&#160;B Preferred Stock do not receive a cash payment for all accumulated and unpaid dividends; rather, all accumulated and unpaid dividends are canceled.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company may, at its option, cause shares of Series&#160;B Preferred Stock to be automatically converted into that number of shares of its common stock that are issuable at the then-prevailing conversion rate. The Company may exercise its conversion right only if the closing price of its common stock exceeds 150% of the then-prevailing conversion price ($1,692.00 per share as of October&#160;31, 2021) for 20 trading&#160;days during any consecutive 30 trading day period, as described in the Series&#160;B Certificate of Designation.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;If the holders of Series&#160;B Preferred Stock elect to convert their shares in connection with certain &#x201c;fundamental changes&#x201d; (as defined in the Series&#160;B Certificate of Designation and described below), the Company will in certain circumstances increase the conversion rate by a number of additional shares of common stock upon conversion or, in lieu thereof, the Company may in certain circumstances elect to adjust the conversion rate and related conversion obligation so that shares of Series&#160;B Preferred Stock are converted into shares of the acquiring or surviving company, in each case as described in the Series&#160;B Certificate of Designation.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The adjustment of the conversion price is to prevent dilution of the interests of the holders of the Series&#160;B Preferred Stock from certain dilutive transactions with holders of the Company&#x2019;s common stock.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;&lt;b style="font-weight:bold;"&gt;Redemption.&lt;/b&gt; The Company does not have the option to redeem the Series&#160;B Preferred Stock.

The right to elect the Series&#160;B Directors will continue for each subsequent annual meeting of the Company&#x2019;s stockholders until all dividends accumulated on the shares of Series&#160;B Preferred Stock have been fully paid or set aside for payment or the Company pays in full or sets aside for payment such redemption price, plus &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;accrued but unpaid dividends, if any, on the redemption date for the shares of Series&#160;B Preferred Stock following a fundamental change.

Each holder of Series&#160;B Preferred Stock will have one vote for each share of Series&#160;B Preferred Stock held in the election of Series&#160;B Directors. The Company previously failed to make timely payment of the accrued dividends on the Series&#160;B Preferred Stock with respect to the May&#160;15, 2019 and August&#160;15, 2019 dividend payment dates.

(&#x201c;FCE&#160;Ltd.&#x201d;), one of the Company&#x2019;s indirect subsidiaries, had 1,000,000 Series&#160;1 Preferred Shares issued and &lt;span style="-sec-ix-hidden:Hidden_bbx7-1ZUAU-mxOvHTlFa7g;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;outstanding&lt;/span&gt;&lt;/span&gt;, which were held solely by Enbridge. The Company guaranteed the return of principal and dividend obligations of FCE&#160;Ltd. to Enbridge, as the holder of the Series&#160;1 Preferred Shares, pursuant to the Guarantee, dated May&#160;27, 2004, made by the Company in favor of Enbridge, as amended by the Guarantee Amending Agreement dated April&#160;1, 2011 and effective as of January&#160;1, 2011 between the Company and Enbridge (the &#x201c;Guarantee&#x201d;). Subsequent to the end of fiscal&#160;year 2020, the Company paid off these obligations to Enbridge. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On January&#160;20, 2020, the Company, FCE&#160;Ltd. and Enbridge entered into a letter agreement (the &#x201c;January&#160;2020 Letter Agreement&#x201d;), pursuant to which they agreed to amend the articles of FCE&#160;Ltd. relating to and setting forth the terms of the Series&#160;1 Preferred Shares to: (i)&#160;remove the provisions of the articles permitting or requiring the issuance of shares of the Company&#x2019;s common stock in exchange for the Series&#160;1 Preferred Shares or as payment of amounts due to the holders of the Series&#160;1 Preferred Shares, (ii)&#160;remove certain provisions of the articles relating to the redemption of the Series&#160;1 Preferred Shares, (iii)&#160;increase the annual dividend rate, commencing on January&#160;1, 2020, to 15%, (iv)&#160;extend the final payment date for all accrued and unpaid dividends and all return of capital payments (i.e., payments of the principal redemption price) from December&#160;31, 2020 to December&#160;31, 2021, (v)&#160;clarify when dividend and return of capital payments were to be made in the future and extend the quarterly dividend and return of capital payments through December&#160;31, 2021 (which were previously to be paid each quarter through December&#160;31, 2020), (vi)&#160;remove certain terms and provisions of the articles that are no longer applicable, and (vii)&#160;make other conforming changes to the articles. The articles of FCE&#160;Ltd. were amended and filed in accordance with the provisions of the January&#160;2020 Letter Agreement on March&#160;26, 2020. Under the amended articles, FCE&#160;Ltd. continued to be required to make (a)&#160;annual dividend payments of Cdn. $500,000&#160;and (b)&#160;annual return of capital payments of Cdn. $750,000.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The amendment to the Series&#160;1 Preferred Shares resulted in an extinguishment of the prior Series&#160;1 Preferred Shares for accounting purposes. A revised fair value was estimated using a discounted cash flow model resulting in a revised carrying value being recorded for the amended Series&#160;1 Preferred Shares of Cdn. $23.4 million (U.S. $17.7 million) as of January&#160;20, 2020, which resulted in a loss of Cdn. $0.2 million (U.S. $0.2 million) recorded in Other income, net on the Consolidated Statements of Operations and Comprehensive Loss during the&#160;year ended October&#160;31, 2020. On an undiscounted basis, the Company&#x2019;s actual aggregate amount of all accrued and unpaid dividends to be paid on the Series&#160;1 Preferred Shares as of October&#160;31, 2020 totaled approximately Cdn. $23.2 million (U.S. $17.4 million) and the balance of the principal redemption price as of October&#160;31, 2020 with respect to all of the Series&#160;1 Preferred Shares totaled approximately Cdn. $4.3 million (U.S. $3.2 million).&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Prior to the amendment, the Company bifurcated embedded derivatives related to the conversion feature and a variable dividend feature. As a result of the January&#160;2020 Letter Agreement, both features were removed from the Series&#160;1 Preferred Shares which resulted in the Company recognizing a gain of $0.6 million related to the extinguishment of the embedded derivatives.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The following summary of the terms of the Series&#160;1 Preferred Shares describes such terms as they existed on October&#160;31, 2019 (prior to any modification covered by the January&#160;2020 Letter Agreement and the resulting amendment of the articles of FCE&#160;Ltd.). The terms of the Series&#160;1 Preferred Shares required (i)&#160;annual dividend payments of Cdn. $500,000 and (ii)&#160;annual return of capital payments of Cdn. $750,000. Dividends accrued at a 1.25% quarterly rate on the unpaid principal balance, and additional dividends accrued on the cumulative unpaid dividends (inclusive of the Cdn. $12.5 million unpaid dividend balance as of the modification date) at a rate of 1.25% compounded quarterly. FCE&#160;Ltd. had the option, subject to the Company having sufficient authorized and unissued shares, of making dividend payments in the form of cash or shares of the Company&#x2019;s common stock under the terms of the Series&#160;1 Preferred Shares.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Because the Series&#160;1 Preferred Shares represented a mandatorily redeemable financial instrument, they were presented as a liability on the Consolidated Balance Sheets.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company made payments of Cdn. $1.9 million (or USD $1.6 million) and Cdn. $0.3 million (or USD $0.2 million) during fiscal&#160;years 2020 and 2019, respectively. The Company&#x2019;s return of capital and dividend payments were not made for the calendar quarters ended on March&#160;31, 2019, June&#160;30, 2019 and September&#160;30, 2019. During fiscal&#160;year 2020, the Company made the return of capital and dividend payments for the obligations due as of March&#160;31, 2019, June&#160;30, 2019 and September&#160;30, 2019. The Company recorded interest expense, which reflects the amortization of the fair value discount of approximately Cdn. $4.0 million (or USD $2.9 million) and Cdn. $3.0 million (or USD $2.3 million) in the fiscal&#160;years ended October&#160;31, 2020 and 2019, respectively. As of October&#160;31, 2020, the carrying value of the Series&#160;1 Preferred Shares was Cdn. $25.6 million ($19.2 million) and was classified as preferred stock obligation of subsidiary on the Consolidated Balance Sheets.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;In December&#160;2020, the Company, FCE&#160;Ltd., and Enbridge entered into a payoff letter, pursuant to which the Company paid all amounts owed to Enbridge under the terms of the Series&#160;1 Preferred Shares. As of the date of the payoff letter, the amount owed to Enbridge under the Series&#160;1 Preferred Shares totaled Cdn. $27.4 million, which included Cdn. $4.3 million of principal and Cdn. $23.1 million of accrued dividends.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On December&#160;18, 2020, the Company remitted payment totaling&#160;Cdn. $27.4 million, or approximately U.S. $21.5 million, to Enbridge. Upon making the payment, the Company recorded a loss on extinguishment for the Series&#160;1 Preferred Shares of $0.9 million. Concurrent with receipt of the payment from the Company, Enbridge surrendered its Series&#160;1 Preferred Shares in FCE&#160;Ltd., and the Guarantee and the January&#160;2020 Letter Agreement were terminated. All obligations related to the Series&#160;1 Preferred Shares were extinguished upon payment.&lt;/p&gt;</us-gaap:PreferredStockTextBlock>

Critical to the success of our business is, among other things, our research and development efforts, both through customer-sponsored projects and Company-sponsored projects. The research and development activities are viewed as another product line that contributes to the development, design, production and sale of fuel cell products, however, it is not considered a separate operating segment. The chief operating decision maker does not review and assess financial information at a discrete enough level to be able to assess performance of research and development activities as if they operated as a standalone business segment, therefore, the Company has identified one business segment: fuel cell power plant production and research.&lt;/p&gt;&lt;p style="font-family:'Times New

Sign-On Award to Jason Few, the Company&#x2019;s President and Chief Executive Officer (the &#x201c;CEO&#x201d;), pursuant to the August&#160;26, 2019 employment agreement between the Company and the CEO. Pursuant to the terms of such Sign-On Award, 500,000 RSUs vest on August&#160;26, 2022. The remaining 500,000 RSUs (&#x201c;Additional RSUs&#x201d;) will vest if, during the 30 days prior to the vesting date of August 26, 2022, the weighted average price of the Company&#x2019;s common stock exceeds $1.00. The number of Additional RSUs will range from zero for a weighted average price of $1.00 to a maximum of 500,000 RSUs for a weighted average price of $6.00, with linear interpolation for stock prices between $1.00 and $6.00. The vesting of all RSUs is subject to the individual&#x2019;s continuous employment with the Company through the vesting date. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The outstanding restricted stock awards and units also include awards made on August&#160;24, 2020, under the FY 2020 LTI Plan, totaling 835,038 RSUs which include 668,030 performance awards and 167,008 time-based awards. Performance awards were issued assuming participants achieve 100% target performance. Should participants achieve the 200% performance level, they will receive up to 545,209 additional RSUs. The performance awards were valued based upon a Monte Carlo Simulation, and the 334,015 relative TSR performance shares were valued at $4.62 per share and the 334,015 absolute performance shares were valued at $5.17 per share. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On November&#160;24, 2020, 848,078 RSUs were awarded under the FY 2021 LTI Plan, which include 551,252 performance units and 296,826 time-based units. Should the Company&#x2019;s share price achieve the 200% performance level, awardees will receive up to 446,158 additional RSUs. The performance units were valued based on a Monte-Carlo Simulation, and the estimated fair value of the 275,626 relative TSR performance units was $14.41 per share and the estimated fair value of the 275,626 absolute TSR performance units was $15.36 per share.

The adoption of the ESPP allows the Company to provide eligible employees of FuelCell Energy,&#160;Inc. and certain of its designated subsidiaries with the opportunity to voluntarily participate in the ESPP, enabling such participants to purchase shares of the Company&#x2019;s common stock at a discount to market price at the time of such &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;purchase. The maximum number of the Company&#x2019;s shares of common stock that may be issued under the ESPP is 30,248 shares.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Under the ESPP, eligible employees have the right to purchase shares of common stock at the lesser of (i)&#160;85% of the last reported sale price of our common stock on the first business day of the offering period, or (ii)&#160;85% of the last reported sale price of the common stock on the last business day of the offering period, in either case rounded up to avoid impermissible trading fractions. Shares issued pursuant to the ESPP contain a legend restricting the transfer or sale of such common stock for a period of 0.5 year after the date of purchase.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The ESPP activity for the&#160;years ended October&#160;31, 2021, 2020 and 2019 was de minimis.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"&gt;Employee Tax-Deferred Savings Plans&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;We offer a 401(k)&#160;plan (the &#x201c;401(k)&#160;Plan&#x201d;) to all full time employees that provides for tax-deferred salary deductions for eligible employees (beginning the first&#160;month following an employee&#x2019;s hire date). Employees may choose to make voluntary contributions of their annual compensation to the 401(k)&#160;Plan, limited to an annual maximum amount as set periodically by the IRS. Employee contributions are fully vested when made. Under the 401(k)&#160;Plan, there is no option available to the employee to receive or purchase our common stock. Matching contributions of 2% under the 401(k)&#160;Plan aggregated $0.4 million, $0.3 million and $0.5 million for the&#160;years ended October&#160;31, 2021, 2020, and 2019, respectively.&lt;/p&gt;</us-gaap:DisclosureOfCompensationRelatedCostsShareBasedPaymentsTextBlock>

style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;We continually evaluate our deferred tax assets as to whether it is &#x201c;more likely than not&#x201d; that the deferred tax assets will be realized. In assessing the realizability of our deferred tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies. Based on the projections for future taxable income over the periods in which the deferred tax assets are realizable, management believes that significant uncertainty exists surrounding the recoverability of the deferred tax assets. As a result, we recorded a valuation allowance against our net deferred tax assets. As of October&#160;31, 2021, we had $368.7 million of federal net operating loss (&#x201c;NOL&#x201d;) carryforwards that expire in the&#160;years 2022 to 2038 and $518.6 million of state NOL carryforwards that expire in the&#160;years 2022 through 2041. Additionally, we had $11.7 million of state tax credits available that will expire from tax&#160;years 2022 to 2040. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;During the&#160;2020 tax year, the Company experienced an &#x201c;ownership change&#x201d; as defined by Internal Revenue Code Section&#160;382. As a result, the utilization of federal and state NOLs generated prior to October&#160;of 2020 is subject to limitation and a reduction was made in fiscal year 2020 to the carrying balance of the federal and state NOLs to reflect the future limitation on utilization. The Company has updated its analysis of potential ownership changes through October 31, 2021 and concluded that no additional ownership changes have occurred subsequent to October 2020. In addition, the acquisition of Versa in fiscal&#160;year 2013 triggered a Section&#160;382 ownership change at the level of Versa Power System which will limit the future usage of some of the federal and state NOLs that we acquired in that transaction. Accordingly, a valuation allowance has been recorded against the deferred tax asset associated with these attributes to reflect the future limitation on utilization.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The Company&#x2019;s financial statements reflect expected future tax consequences of uncertain tax positions that the Company has taken or expects to take on a tax return (including a decision whether to file or not file a return in a particular jurisdiction) presuming the taxing authorities&#x2019; full knowledge of the position and all relevant facts.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;The liability for unrecognized tax benefits as of October&#160;31, 2021 and 2020 was $0. Due to the Section&#160;382 ownership change that occurred in 2020, the underlying NOLs associated with any historical uncertain tax position, are no longer available for utilization, and therefore a deferred tax asset is not recorded on the Consolidated Balance Sheet and the uncertain tax position was released in 2020. It is our policy to record interest and penalties on unrecognized tax benefits as income taxes; however, because of our significant NOLs, no provision for interest or penalties has been recorded. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;We file income tax returns in the U.S. and certain states, primarily Connecticut and California, as well as income tax returns required internationally for South Korea and Germany. We are open to examination by the IRS and various states in which we file for fiscal&#160;year 2002 to the present. &lt;/p&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

Under the terms of such service agreements, the particular power plant must meet a minimum operating output during defined periods of the term. If minimum output falls below the contract requirement, the Company may be subject to performance penalties and/or may be required to repair or replace the customer&#x2019;s fuel cell module(s).&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"&gt;Power Purchase Agreements&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;Under the terms of the Company&#x2019;s PPAs, customers agree to purchase power from the Company&#x2019;s fuel cell power plants at negotiated rates. Electricity rates are generally a function of the customers&#x2019; current and estimated future electricity pricing available from the grid. As owner or lessee of the power plants, the Company is responsible for all operating costs necessary to maintain, monitor and repair the power plants. Under certain agreements, the Company is also responsible for procuring fuel, generally natural gas or biogas, to run the power plants. In addition, under the terms of some of the PPAs, the Company may be subject to a performance penalty if the Company does not meet certain performance requirements.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="font-style:italic;font-weight:bold;"&gt;Project Fuel Exposure&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="margin-bottom:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Certain of our PPAs for project assets in the Company&#x2019;s generation operating portfolio and project assets under construction expose us to fluctuating fuel price risks as well as the risk of being unable to procure the required amounts of fuel and the lack of alternative available fuel sources. The Company seeks to mitigate our fuel risk using strategies including: (i) fuel cost reimbursement mechanisms in our PPAs to allow for pass through of fuel costs (full or partial) where possible which we have done with our 14.9 MW operating project in Bridgeport, CT and our 7.4 MW project under &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;construction in Hartford, CT; (ii) procuring fuel under fixed price physical contracts with investment grade counterparties which we have done for twenty years under our Tulare BioMAT project and the initial seven years of the twenty year PPA for our LIPA Yaphank, NY project; and (iii) entering into financial hedges with investment grade counterparties to offset potential negative market fluctuations.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="margin-bottom:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;The Company currently has three projects in development with fuel sourcing risk, which are the Toyota Project which requires procurement of RNG, and our Derby, CT 14.0 MW and 2.8 MW projects, which require natural gas. Fuel sourcing and risk mitigation strategies for all three projects are being assessed and will be implemented as project operational dates become firm. Such strategies may require cash collateral or reserves to secure fuel or related contracts for these three projects. If the Company is unable to secure fuel on favorable economic terms, it may result in impairment charges to these project assets.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"&gt;Other&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;As of October&#160;31, 2021, the Company had unconditional purchase commitments aggregating $71.1 million, for materials, supplies and services in the normal course of business.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"&gt;Legal Proceedings&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;POSCO Energy Matters&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;From approximately 2007 through 2015, the Company relied on POSCO Energy Co., Ltd.

Due to certain actions and inactions of POSCO Energy, the Company has not realized any new material revenues, royalties or new projects developed by POSCO Energy since late 2015.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;In November&#160;2019, POSCO Energy spun-off its fuel cell business into a new entity, Korea Fuel Cell Co.,&#160;Ltd. (&#x201c;KFC&#x201d;), without the Company&#x2019;s consent. As part of the spin-off, POSCO Energy transferred manufacturing and service rights under the License Agreements to KFC, but retained distribution rights and severed its own liability under the License Agreements. The Company formally objected to POSCO Energy&#x2019;s spin-off, and POSCO Energy posted a bond to secure any liabilities to the Company arising out of the spin-off. In September&#160;2020, the Korean Electricity Regulatory Committee found that POSCO Energy&#x2019;s spin-off of the fuel cell business to KFC may have been done in violation of South Korean law.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On February&#160;19, 2020, the Company notified POSCO Energy in writing that it was in material breach of the License Agreements by (i)&#160;its actions in connection with the spin-off of the fuel cell business to KFC, (ii)&#160;its suspension of performance through its cessation of all sales activities since late 2015 and its abandonment of its fuel cell business in Asia, and (iii)&#160;its disclosure of material nonpublic information to third parties and its public pronouncements about the fuel cell business on television and in print media that have caused reputational damage to the fuel cell business, the Company and its products. The Company also notified POSCO Energy that, under the terms of the License Agreements, it had 60&#160;days to fully cure its breaches to the Company&#x2019;s satisfaction and that failure to so cure would lead to termination of the License Agreements. Further, on March&#160;27, 2020, the Company notified POSCO Energy of additional instances of its material breach of the License Agreements based on POSCO Energy&#x2019;s failure to pay royalties required to be paid in connection with certain module exchanges.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;On April&#160;27, 2020, POSCO Energy initiated a series of three arbitration demands against the Company at the International Court of Arbitration of the International Chamber of Commerce seated in Singapore, in which it alleged certain warranty defects in a sub-megawatt conditioning facility at its facility in Pohang, South Korea and sought combined damages of approximately $3.3 million. Prior to filing the arbitrations, POSCO Energy obtained provisional attachments from the &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Seoul Central District Court attaching certain revenues owed to the Company by Korea Southern Power Company (&#x201c;KOSPO&#x201d;) as part of such warranty claims, which delayed receipt of certain payments owed to the Company. POSCO Energy subsequently sought additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on unspecified warranty claims in an additional amount of approximately $7 million, and additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on its alleged counterclaims in the license termination arbitration described below in an additional amount of approximately $110 million. As of October&#160;31, 2021, outstanding accounts receivable due from KOSPO were $11.2 million. &lt;span style="background:#ffffff;"&gt;POSCO Energy posted a bond in the amount of &lt;/span&gt;&lt;span style="background:#ffffff;"&gt;$46&lt;/span&gt;&lt;span style="background:#ffffff;"&gt;&#160;million to secure any damages to the Company resulting from the attachments.&lt;/span&gt;&lt;span style="font-size:12pt;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="font-size:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On June&#160;28, 2020, the Company terminated the License Agreements and filed a demand for arbitration against POSCO Energy and KFC in the International Court of Arbitration of the International Chamber of Commerce based on POSCO Energy&#x2019;s (i)&#160;failure to exercise commercially reasonable efforts to sell the Company&#x2019;s technology in the South Korean and Asian markets, (ii)&#160;disclosure of the Company&#x2019;s proprietary information to third parties, (iii)&#160;attack on the Company&#x2019;s stock price and (iv)&#160;spin-off of POSCO Energy&#x2019;s fuel cell business into KFC without the Company&#x2019;s consent. The Company requested that the arbitral tribunal (a)&#160;confirm through declaration that POSCO Energy&#x2019;s exclusive license to market the Company&#x2019;s technology and products in South Korea and Asia is null and void as a result of the breaches of the License Agreements and that the Company had the right to pursue direct sales in these markets, (b)&#160;order POSCO Energy and KFC to compensate the Company for losses and damages suffered in the amount of more than $200 million, and (c)&#160;order POSCO Energy and KFC to pay the Company&#x2019;s arbitration costs, including counsel fees and expenses. The Company retained outside counsel on a contingency basis to pursue its claims, and outside counsel entered into an agreement with a litigation finance provider to fund the legal fees and expenses of the arbitration. In October&#160;2020, POSCO Energy filed a counterclaim in the arbitration (x)&#160;seeking approximately $880 million in damages based on allegations that the Company misrepresented the capabilities of its fuel cell technology to induce POSCO Energy to enter into the License Agreements and failed to turn over know-how sufficient for POSCO Energy to successfully operate its business; (y)&#160;seeking a declaration that the License Agreements remained in full force and effect and requesting the arbitral tribunal enjoin the Company from interfering in POSCO Energy&#x2019;s exclusive rights under the License Agreements and (z)&#160;seeking an order that the Company pay POSCO Energy&#x2019;s arbitration costs, including counsel fees and expenses.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;In July 2020, the Company discontinued revenue recognition of the deferred license revenue related to the License Agreements given the then pending arbitrations.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;On August&#160;28, 2020, POSCO Energy filed a complaint in the Court of Chancery of the State of Delaware (the &#x201c;Court&#x201d;) purportedly seeking to enforce its rights as a stockholder of the Company to inspect and make copies and extracts of certain books and records of the Company and/or the Company&#x2019;s subsidiaries pursuant to Section&#160;220 of the Delaware General Corporation Law and/or Delaware common law. POSCO Energy alleged that it was seeking to inspect these documents for a proper purpose reasonably related to its interests as a stockholder of the Company, including investigating whether the Company&#x2019;s Board of Directors and its management breached their fiduciary duties of loyalty, due care, and good faith. POSCO Energy sought an order of the Court permitting POSCO Energy to inspect and copy the demanded books and records, awarding POSCO Energy reasonable costs and expenses, including reasonable attorney&#x2019;s fees incurred in connection with the matter, and granting such other and further relief as the Court deemed just and proper. On July 9, 2021, the Court issued a post-trial ruling denying POSCO Energy&#x2019;s demand to inspect the Company&#x2019;s books and records because POSCO Energy lacked a proper purpose. The Court held that the totality of the circumstances, including the fact that this complaint was the seventh legal action POSCO Energy initiated against the Company within the span of nine months, confirmed that POSCO Energy&#x2019;s purpose in initiating the books and records demand and filing the complaint was not proper. As this dispute was resolved by the Court as described above, it did not require resolution pursuant to, and was not part of, the Settlement Agreement described in Note 24. &#x201c;Subsequent Events.&#x201d;&lt;span style="font-size:12pt;"&gt; &lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"&gt;&lt;span style="font-size:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;On September&#160;14, 2020, POSCO Energy filed a complaint in the United States District Court for the Southern District of New York (the &#x201c;SD Court&#x201d;) alleging that the Company delayed the removal of restrictive legends on certain share certificates held by POSCO Energy in 2018, thus precluding POSCO Energy from selling the shares and resulting in claimed losses in excess of $1.0 million. On September 16, 2021, the SD Court ruled in the Company&#x2019;s favor on a motion for summary judgement dismissing all four counts of POSCO Energy&#x2019;s complaint regarding share certificates held by POSCO Energy in 2018, but granted POSCO Energy leave to file an amended complaint.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;In order to resolve the disputes described above (other than the books and records dispute which was resolved by the Court), on December 20, 2021, the Company entered into the Settlement Agreement with POSCO Energy and KFC. For more information on the Settlement Agreement, refer to Note 24. &#x201c;Subsequent Events&#x201d;.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Other Legal Proceedings&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;From time to time, the Company is involved in other legal proceedings, including, but not limited to, regulatory proceedings, claims, mediations, arbitrations and litigation, arising out of the ordinary course of its business (&#x201c;Other Legal Proceedings&#x201d;). Although the Company cannot assure the outcome of such Other Legal Proceedings, management presently believes that the result of such Other Legal Proceedings, either individually, or in the aggregate, will not have a material adverse effect on the Company&#x2019;s consolidated financial statements, and no material amounts have been accrued in the Company&#x2019;s consolidated financial statements with respect to these matters.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;"&gt;Impact of the COVID-19 Pandemic&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;During fiscal&#160;year 2020, the Company launched a proactive response to the escalating COVID-19 outbreak and temporarily suspended operations at its Torrington, Connecticut manufacturing facility in March&#160;2020. The Company also commenced remote work protocol for those employees worldwide that were capable of working from home. The Company took these actions to secure the safety of the Company&#x2019;s employees, our corporate community as a whole, and the communities in which our team members live, and to adhere to Centers for Disease Control (CDC) recommendations of social distancing and limited public exposure in connection with the COVID-19 pandemic. All employees that were not able to work from home during the manufacturing facility shutdown due to their job function received full wages and benefits during such time. We did not implement any furlough, layoff or shared work program during such time. The Company resumed manufacturing in June&#160;2020 and the Torrington, Connecticut manufacturing facility employees returned to work. We established a phased-in return to work schedule commencing March&#160;15, 2021 for those employees working from home which was completed in April 2021. We will continue to evaluate our ability to operate in the event of a resurgence of COVID-19 and the advisability of continuing operations based on federal, state and local guidance, evolving data concerning the pandemic and the best interests of our employees, customers and stockholders. In addition, given the continued elevated number of &#160;COVID-19 cases throughout the U.S. as a result of the highly transmissible Delta and Omicron variants, the Company instituted policies to protect its employees and customers &#160;such as a mandatory vaccination policy which required all U.S. employees to be fully vaccinated by November 1, 2021 or seek a qualified religious and/or medical exemption with weekly testing protocols.&lt;/p&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

Franklin Park&#x2019;s tax equity commitment totals $12.4 million.&#160;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="margin-bottom:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;This transaction was structured as a &#x201c;partnership flip,&#x201d; which is a structure commonly used by tax equity investors in the financing of renewable energy projects. Under this partnership flip structure, a partnership, in this case YTBFC Holdco, LLC (the &#x201c;Yaphank Partnership&#x201d;), was organized to acquire from FuelCell Energy Finance II, LLC, a wholly-owned subsidiary of the Company, all outstanding equity interests in Yaphank Fuel Cell Park, LLC (the &#x201c;Yaphank Project Company&#x201d;) which in turn owns the LIPA Yaphank Project and is the party to the power purchase agreement and all project agreements. At the closing of the transaction, the Yaphank Partnership is owned by Franklin Park, holding Class A Units, and Fuel Cell Energy Finance Holdco, LLC, a subsidiary of FuelCell Energy Finance, LLC, holding Class B Units. The acquisition of the Yaphank Project Company by the Yaphank Partnership was funded in part by an initial draw from Franklin Park and funds contributed downstream to the Yaphank Partnership by the Company. The initial funding occurred on December 13, 2021, upon the satisfaction of certain conditions precedent (including the receipt of an appraisal and confirmation that the LIPA Yaphank Project would be eligible for the investment tax credit (&#x201c;ITC&#x201d;) under Section 48 of the Internal Revenue Code of 1986, as amended). &#160;In connection with the initial closing, the Company was able to draw down approximately $3.2 million, of which approximately $0.4 million was used to pay closing costs, including title insurance expenses and legal and consulting fees. The Company is eligible to draw the remaining amount of the commitment, approximately $9.2 million, once the LIPA Yaphank Project achieves commercial operation. &#160;When such funds are drawn down, the funds will be distributed upstream to the Company, as a reimbursement of prior construction costs incurred by the Company.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="margin-bottom:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Under a partnership flip structure, tax equity investors agree to receive a minimum target rate of return, typically on an after-tax basis. Prior to receiving a contractual rate of return or a date specified in the contractual arrangements, Franklin Park will receive substantially all of the non-cash value attributable to the LIPA Yaphank Project, which includes accelerated depreciation and Section 48(a) investment tax credits; however, the Company will receive a majority of the cash distributions (based on the operating income of the LIPA Yaphank Project), which are paid quarterly. After Franklin Park receives its contractual rate of return, the Company will receive approximately 95% of the cash and tax allocations. The Company (through a separate wholly owned entity) may enter into a back leverage debt financing transaction and use the cash distributions from the Yaphank Partnership to service the debt. &#160;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Under this partnership flip structure, after the fifth anniversary following commercial operations, we have an option to acquire all of the equity interests that Franklin Park holds in the Yaphank Partnership starting after Franklin Park receives its contractual rate of return (the anticipated &#x201c;flip&#x201d; date) after the LIPA Yaphank Project is operational. If we exercise this option, we will be required to pay the greater of the following: (i) the fair market value of Franklin Park's equity interest at the time the option is exercised or (ii) an amount equal 9.6% of Franklin Park&#x2019;s capital contributions. This option payment is to be grossed up for federal taxes if it exceeds the tax basis of the Yaphank Partnership Class A Units.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:10pt 0pt 0pt 0pt;"&gt;&lt;i style="font-style:italic;"&gt;Settlement Agreement with POSCO Energy and KFC&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;background:#ffffff;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="background:#ffffff;"&gt;In order to resolve the disputes among POSCO Energy, KFC and us described above in Note 22. &#x201c;Commitments and Contingencies&#x201d; (other than the book and records dispute which was previously resolved), on December 20, 2021, the Company entered into a Settlement Agreement (the &#x201c;Settlement Agreement&#x201d;) with POSCO Energy and KFC (POSCO Energy and KFC may be collectively referred to herein as &#x201c;PE Group&#x201d;). The Settlement Agreement provides, among other things, that the parties will cooperate in good faith to effect a market transition to the Company of the molten carbonate fuel cell business in Korea in accordance with the terms and conditions of the Settlement Agreement. To that end, the Settlement Agreement provides that any and all past, current, or potential disputes and claims between the Company, on the one hand, and POSCO Energy and KFC, on the other, of any nature whatsoever, whether known or unknown, asserted or not asserted, based on actions or omissions of any party on or before the date of Settlement Agreement are fully and finally settled, including such disputes and claims, directly or indirectly, in connection with the legal disputes (other than the books and records dispute which was previously resolved) and License Agreements described above in Note 22. &#x201c;Commitments and Contingencies,&#x201d; with the exception of (i) an unfiled claim by the Company in the amount of &lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="background:#ffffff;"&gt;approximately &lt;/span&gt;&lt;span style="background:#ffffff;"&gt;$1.8&lt;/span&gt;&lt;span style="background:#ffffff;"&gt; million with respect to certain royalties the Company believes are owed by POSCO Energy with respect to replacement modules deployed by POSCO Energy at Gyenonggi Green Energy and other sites for which POSCO Energy has not paid royalties, and (ii) an unfiled claim by POSCO Energy in an unknown amount with respect to a series of purchase orders for materials and components which began in 2014 under a supply chain contract, both of which claims remain unsettled. The Company does not believe the claim by POSCO Energy with respect to purchase orders for materials and components under the supply chain contract has merit and the Company retains the right to file a counterclaim for damages it believes it has incurred with respect to such supply chain contract. With respect to&lt;/span&gt; the attachments obtained by POSCO Energy from the Seoul Central District Court with respect to certain revenues owed to the Company by KOSPO (which are described in more detail in Note 22. &#x201c;Commitments and Contingencies&#x201d;)&lt;span style="background:#ffffff;"&gt;, the Settlement Agreement provides that, within &lt;/span&gt;&lt;span style="background:#ffffff;"&gt;five days&lt;/span&gt;&lt;span style="background:#ffffff;"&gt; of the date of the Settlement Agreement, POSCO Energy will file an application with the Seoul Central District Court to revoke the attachments. Thereafter, the Company expects to promptly receive the outstanding KOSPO accounts receivable of approximately &lt;/span&gt;$11.2 million held by the Seoul Central District Court. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:10pt 0pt 0pt 0pt;"&gt;Under the Settlement Agreement, the parties have also agreed that, within five days of the date thereof, the Company will&#160;withdraw its objection to the spin-off of KFC from POSCO Energy, and that the License Agreements are not terminated, but instead are deemed to be amended such that POSCO Energy and KFC only have the right (i) to provide maintenance and repair services to PE Group&#x2019;s existing customers on existing molten carbonate power generation and thermal projects under long-term service agreements currently in force as well as long-term service agreements that have expired and are pending renewal as of the settlement date (collectively, &#x201c;Existing LTSAs&#x201d;), (ii) to supply replacement modules purchased from the Company only for their existing customers for existing molten carbonate power generation and thermal projects under Existing LTSAs and (iii) to own, operate and maintain all facilities and factories solely for the purposes set forth in (i) and (ii) above (collectively, the &#x201c;Right to Service License&#x201d;). POSCO Energy and KFC further agree that, as of the date of the Settlement Agreement, the License Agreements are deemed to be amended such that the Company exclusively enjoys all rights as to its technology in Korea and Asia, other than the Right to Service License. The Settlement Agreement further provides that the License Agreements will terminate automatically upon sixty days prior written notice to PE Group if (i) the Company enters into a business collaboration agreement with a Korean company to construct, assemble, manufacture, market, sell, distribute, import, export, install, commission, service, maintain, or repair products incorporating the Company&#x2019;s technology, or otherwise conduct the Company&#x2019;s business, in the Korean market; or (ii) the Company expands the capacity of its existing Korean entity such as to perform such activities itself. In the event of the termination of the License Agreements, the license granted to PE Group under the Right to Service License will continue notwithstanding the termination of the License Agreements, except that PE Group&#x2019;s right to own, operate, and maintain all facilities and factories for the purpose of servicing any orders or requests made by the Company will terminate. For the avoidance of doubt, pursuant to the terms of the Settlement Agreement, PE Group has no right to manufacture modules or any other product incorporating the Company&#x2019;s technology under the License Agreements as amended, the Right to Service License or otherwise unless requested and authorized by the Company to do so. &#160;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"&gt;The Settlement Agreement further provides that, in order to service its existing customers under the Existing LTSAs, KFC will place a firm, non-cancelable order for twelve SureSource 3000 modules within two weeks after the date of the Settlement Agreement and an additional firm, non-cancelable order for eight SureSource 3000 modules on or before June 30, 2022, all at a price of $3.0 million per module. In addition, KFC agrees to use commercially reasonable efforts to order fourteen additional SureSource 3000 modules by December 31, 2022, at a price of $3.0 million per module if ordered by such date. If KFC materially breaches the Settlement Agreement by failing to make timely and full payment for the modules for which KFC is required to place orders under the Settlement Agreement and does not cure such material breach within fifteen days of notice of such breach by the Company, the License Agreements and the Right to Service License granted to PE Group will be terminated. If the Company materially breaches the Settlement Agreement by failing to supply the modules for which KFC is required to place orders under the Settlement Agreement, as long as KFC has made the payment for such modules and has otherwise satisfied its contractual obligations for those modules and such material breach is not cured within sixty days after notice from PE Group, PE Group will have the right to terminate the Settlement Agreement. With respect to any other alleged breach, material or otherwise, of the Settlement Agreement, the parties&#x2019; exclusive remedy consists solely of general damages.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"&gt;Pursuant to the Settlement Agreement, with respect to new modules to be supplied by the Company and deployed by PE Group to its existing customers, the Company will provide its standard warranty against module defects until the earlier of eighteen months from the date of shipment or twelve months from the date of installation. As part of the global settlement of the disputes among the parties and subject to the qualifications set forth in the Settlement Agreement, the Company will reimburse PE Group for any annual output penalty amount paid by PE Group to its customers pursuant to Existing LTSAs (whether such Existing LTSA is extended or renewed), caused by a shortfall or defect in the new modules for a period of up to seven years. The maximum annual reimbursement obligation with regard to any PE Group customer for any new module provided by the Company will not exceed an amount equal to 7.5% per year of the module purchase &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"&gt;price. The Company will not be required to reimburse PE Group for any penalty paid by PE Group under the Existing LTSAs that is not caused by a shortfall or defect in the modules to be supplied by the Company including, without limitation, any shortfall or defect caused by a site-related problem, a problem with the balance of plant, or other components of the project.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;padding-top:10pt;text-align:justify;margin:0pt;"&gt;Although the Company has the exclusive and unrestricted right under the Settlement Agreement to perform, pursue, and otherwise conduct its business in relation to new fuel cell projects (including new projects with PE Group&#x2019;s existing customers) in Korea and Asia, the parties have agreed that, except as further provided in the Settlement Agreement with respect to PE Group&#x2019;s existing customers Noeul Green Energy and Godeok Green Energy, the Company will not engage in discussions with PE Group&#x2019;s existing customers regarding Existing LTSAs without PE Group&#x2019;s consent. The parties have further agreed that if PE Group cannot enter into an agreement with its existing customers to extend or renew Existing LTSAs by December 31, 2022, PE Group will cooperate with the Company so that the Company may discuss and, at the Company&#x2019;s sole discretion, enter into an extension of an Existing LTSA, a new long-term service agreement to replace an Existing LTSA, or a module sales agreement with PE Group&#x2019;s existing customers; provided that (i) should the Company enter into such an arrangement with a PE Group existing customer, and (ii) the Company is required to provide replacement modules to such existing customer under such arrangement, and (iii) PE Group has not already deployed all or some the modules that PE Group ordered under Settlement Agreement, the Company will purchase the number of required replacement modules from PE Group at a price of $3.0 million per module (to the extent such modules are available and have not yet been deployed). The purchase of such replacement modules by the Company is contingent upon the modules being in proper condition as determined by inspection process to be agreed by the parties. Any modules purchased by the Company from PE Group under these terms will be included as part of the firm orders KFC is required to make pursuant to the Settlement Agreement.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"&gt;With respect to operations and maintenance agreements, the Settlement Agreement provides that KFC will have the right of first refusal on providing operation and maintenance services on commercially reasonable terms for new long-term service agreements entered into by the Company in Korea for a period of the first to occur of either twenty-four months after the date of the Settlement Agreement or until such time as the Company engages a third party capable of providing such services in Korea. If KFC and the Company agree that KFC should provide operation and maintenance services pursuant to the right of first refusal, KFC and the Company will enter into one or more operation and maintenance agreements that reflect commercially reasonable terms and conditions as agreed by KFC and the Company at that time.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;background:#ffffff;margin:0pt;"&gt;&#160;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"&gt;With respect to balance of plant (&#x201c;BOP&#x201d;), KFC currently has eight units of BOP available, and the Settlement Agreement provides that the Company has the option to purchase such units of BOP for any new molten carbonate fuel cell projects within Korea at a price of KRW 2,550,000,000 per unit. The Company will also have a non-exclusive, non-transferrable, non-sublicensable license to use the intellectual property imbedded in the BOP units in Korea in consideration for a reasonable license fee to be separately agreed by the parties. Detailed terms and conditions of BOP and related software and firmware supply will be discussed and agreed in good faith in separate BOP supply agreements in the event the Company exercises its option to purchase any of such BOP.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;background:#ffffff;margin:0pt;"&gt;&#160;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;background:#ffffff;margin:0pt;"&gt;The Company&#160;retained outside counsel on a contingency basis to pursue its claims against POSCO Energy and KFC, and outside counsel entered into an agreement with a litigation finance provider to fund the legal fees and expenses of the arbitration proceedings brought by the Company against POSCO Energy and KFC. As the Company has entered into the Settlement Agreement, it is required to remit fees to its counsel, Wiley Rein, LLP (&#x201c;Wiley&#x201d;), subject to the terms of its engagement letter with Wiley. On December 23, 2021, the Company agreed that it will pay Wiley a total of $24.0 million to satisfy all obligations to Wiley under the Company&#x2019;s engagement letter, of which $14.0 million will be paid on or before December 30, 2021, $5.0 million will be paid on or before March 30, 2022, and $5.0 million will be paid on or before June 30, 2022.&lt;/p&gt;</us-gaap:SubsequentEventsTextBlock>
