   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Fuel Tech, Inc. and subsidiaries ("Fuel Tech", the "Company", "we", "us" or "our") develops and provides&#xa0;proprietary technologies for air pollution control, process optimization, water treatment, and advanced engineering services. These technologies enable customers to operate in a cost-effective and environmentally sustainable manner.</p>

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">The Company&#x2019;s nitrogen oxide (NOx) reduction technologies reduce nitrogen oxide emissions from boilers, furnaces, and other stationary combustion sources.&#xa0;To reduce NOx emissions, our technologies utilize advanced combustion modification techniques and post-combustion NOx control approaches including non-catalytic, catalytic, and combined systems.&#xa0;The Company also&#xa0;provides solutions for the mitigation of particulate matter, including particulate control with electrostatic precipitator products and services, and using flue gas conditioning systems which modify the ash properties of particulate for improved collection efficiency. The Company&#x2019;s FUEL CHEM&#xae; technology improves the efficiency, reliability, fuel flexibility, boiler heat rate, and environmental status of combustion units by controlling slagging, fouling, corrosion, and opacity. Water treatment technologies include DGI&#x2122; Dissolved Gas Infusion Systems which utilize a patented nozzle to deliver supersaturated oxygen solutions and other gas-water combinations to target process applications or environmental issues. This infusion process has a variety of applications in the water and wastewater industries, including remediation, aeration, biological treatment, and wastewater odor management.</p>

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Many of Fuel Tech&#x2019;s products and services rely heavily on the Company&#x2019;s&#xa0;Computational Fluid Dynamics modeling capabilities, which are enhanced by internally developed, high-end visualization software.</p>

The Company records liabilities where a contingent loss is probable and can be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when <em style="font: inherit;">no</em> amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is <em style="font: inherit;">not</em> probable or the amount is <em style="font: inherit;">not</em> estimable, or both, if there is a reasonable possibility that a material loss <em style="font: inherit;"> may </em>have been incurred.</p>

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Fuel Tech issues a standard product warranty with the sale of its products to customers. Our recognition of warranty liability is based primarily on analyses of warranty claims experienced in the preceding years as the nature of our historical product sales for which we offer a warranty are substantially unchanged. This approach provides an aggregate warranty accrual that is historically aligned with actual warranty claims experienced.</p>

  <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"><span style="background-color:#ffffff;">In the second quarter of 2022, the Company continued to experience a challenging operational environment resulting from the ongoing substitution of gas-fired and renewable energy plants for coal-fired installations and&#xa0;the ongoing impacts of geopolitical events and the coronavirus (COVID-19) global pandemic.&#xa0;We continue to invest in new technologies to expand our product offerings into the water pollution control and treatment market. In June, the Board approved a plan to invest excess capital&#xa0;to provide returns on excess cash, while preserving capital and&#xa0;managing liquidity. Our capital resources are sufficient for our immediate and longer-term needs, and we continue to enjoy the services and support of a dedicated workforce.&#xa0;We expect that our cost control efforts will maintain our existing levels of operating expenditures&#xa0;and the diminishing effects of the pandemic should lead to an improved market outlook.</span></p>

  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; text-align: justify;"><span style="background-color:#ffffff;">The effects&#xa0;of the COVID-19&#xa0;global pandemic have&#xa0;presented&#xa0;significant risks to the Company, not all of which the Company is able to fully evaluate or even foresee at the current time. Although the impact of the pandemic is difficult to quantify, the Company has experienced, and may continue to experience, reductions in demand for certain of our products&#xa0;due to the delay or abandonment of ongoing or anticipated projects due to our customers&#x2019;, suppliers&#x2019; and other third parties&#x2019; financial distress or concern regarding the volatility of global markets.&#xa0;Geopolitical events and global economic sanctions resulting from the ongoing conflict between Russia and Ukraine may impact new or existing projects and the prices and availability of raw materials, energy and other materials.&#xa0;These events may also impact energy and regulatory policy nationally or regionally for the impacted regions.&#xa0;Management cannot predict the full impact of the COVID-19 pandemic and geopolitical events on the Company&#x2019;s sales and marketing channels and supply chain, and as a result, the ultimate extent of the effects on the Company is highly uncertain and will depend on future developments. Such effects could exist for an extended period of time. The Company continues to monitor the potential impacts on the business.&#xa0;</span></p>

We are also encouraged by the pace and depth of our business development activities, which reflects an increased focus on global emissions protocols across a variety of fuel sources.&#xa0;Our Consolidated APC backlog at </span>June 30, 2022<span style="background-color:#ffffff;"> was $</span>10,547<span style="background-color:#ffffff;">&#xa0;and our global sales pipeline is in the $50 -75 million range.</span></p>

The Company is projecting a consolidated effective tax rate of approximately&#xa0;0% for </span>2022<span style="background-color:#ffffff;">, which is lower than the federal income tax rate of 21%. The Company's effective tax rate differs from the statutory federal tax rate of 21% for the </span>three and six<span style="background-color:#ffffff;"> month periods ended </span>June 30, 2022<span style="background-color:#ffffff;"> primarily due to a full valuation allowance recorded on our United States, China and Italy deferred tax assets since we cannot anticipate when or if we will have sufficient taxable income to utilize the deferred tax assets in the future. Further, our effective tax rate differs from the statutory federal tax rate due to state taxes, differences between U.S. and foreign tax rates, foreign losses incurred with no related tax benefit, non-deductible commissions, and non-deductible meals and entertainment expenses.</span></p>

  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify;">The effects&#xa0;of the COVID-19&#xa0;global pandemic have presented&#xa0;significant risks to the Company, not all of which the Company is able to fully evaluate or even foresee at the current time. Although the impact of the pandemic is difficult to quantify, the Company has experienced, and may continue to experience, reductions in demand for certain of our products&#xa0;due to the delay or abandonment of ongoing or anticipated projects due to our customers&#x2019;, suppliers&#x2019; and other third parties&#x2019; financial distress or concern regarding the volatility of global markets. Other directly or indirectly COVID-19 related effects, such as supply chain disruptions and&#xa0;travel restrictions,&#xa0;have been impacting operations and financial performance to varying degrees. We continue to monitor our liquidity needs and in response to our recent periods of declines in revenue and net losses have taken measures to reduce expenses and restructure operations which we feel are necessary to ensure we maintain sufficient working capital and liquidity to operate the business and invest in our future. We have evaluated our ongoing business needs&#xa0;and considered the cash requirements of our base business of Air Pollution Control and FUEL CHEM, as well as our efforts to wind-down our APC operations in China. This evaluation included consideration of the following: a) customer and revenue trends in our APC and FUEL CHEM business segments, b) current operating structure and expenditure levels, and c) the costs of winding down our APC operations in China as well as other research and development initiatives.&#xa0;Based on this analysis, management believes that currently we have sufficient cash and working capital to operate our base APC and FUEL CHEM businesses.&#xa0;We believe our current cash position and net cash flows expected to be generated from operations are adequate to fund planned operations&#xa0;of the Company for the next 12 months.</p>

The funds would be held in money market funds until they are invested in those securities. The investments would be structured to create a maturity &#x201c;ladder&#x201d; where the proceeds from maturities are re-invested to maintain a balance of short- and long-term investments based on the expected business needs. Maturities will be between three and thirty-six months. This strategy allows the Company to provide returns on excess cash, while managing liquidity and minimizing exposure to interest rate fluctuations.</span></p>

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">The Company&#8217;s nitrogen oxide (NOx) reduction technologies reduce nitrogen oxide emissions from boilers, furnaces, and other stationary combustion sources.&#160;To reduce NOx emissions, our technologies utilize advanced combustion modification techniques and post-combustion NOx control approaches including non-catalytic, catalytic, and combined systems.&#160;The Company also&#160;provides solutions for the mitigation of particulate matter, including particulate control with electrostatic precipitator products and services, and using flue gas conditioning systems which modify the ash properties of particulate for improved collection efficiency. The Company&#8217;s FUEL CHEM&#174; technology improves the efficiency, reliability, fuel flexibility, boiler heat rate, and environmental status of combustion units by controlling slagging, fouling, corrosion, and opacity. Water treatment technologies include DGI&#8482; Dissolved Gas Infusion Systems which utilize a patented nozzle to deliver supersaturated oxygen solutions and other gas-water combinations to target process applications or environmental issues. This infusion process has a variety of applications in the water and wastewater industries, including remediation, aeration, biological treatment, and wastewater odor management.</p>

At <em style="font: inherit;"> June 30, 2022, </em>$10,000 was invested in a money market fund with the intent to purchase debt securities in the near term. A portion of the funds invested are restricted as collateral under the Investment Collateral Security agreement (see Note <em style="font: inherit;">10</em>).&#160;</span></p>

   <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0px; text-align: justify;"><span style="background-color:#ffffff;">We consider all highly liquid debt investments with original maturities from the date of purchase of <em style="font: inherit;">three</em> months or less as cash equivalents. Cash equivalents include investments in money market funds. Carrying value of cash equivalents approximates fair value due to the maturities of <em style="font: inherit;">3</em> months or less.</span></p>

   <p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"><span style="background-color:#ffffff;">Our investments in debt securities consist of Unites States (US) Treasury securities, including Notes, Bonds, and Bills, and US Government Agency securities, that are designated as held-to-maturity (HTM) and stated at amortized cost. The Company has the positive intent and ability to hold these investments to maturity and does&#160;<em style="font: inherit;">not</em> expect&#160;to sell any debt securities before maturity to settle an obligation under the Investment Collateral Security agreement. The maturities of our HTM investments range from 3 to 36 months. HTM debt investments with original maturities of approximately <em style="font: inherit;">three</em> months or less from the date of purchase are classified within cash and cash equivalents. HTM debt investments with original maturities at the date of purchase greater than approximately <em style="font: inherit;">three</em> months and remaining maturities of less than <em style="font: inherit;">one</em> year are classified as short-term investments. HTM debt investments with remaining maturities beyond <em style="font: inherit;">one</em> year are classified as other long-term investments. Interest income, including amortization of premium and accretion of discount, are included on the Condensed Consolidated Statements of Operations in Interest income under the effective yield method.&#160;Discounts or premiums are included in the effective yield and amortized on a straight-line until maturity.</span></p><p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"><span style="background-color:#ffffff;">&#160;</span></p><p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"/>

   <p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;">&#160;</p>
   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">The timing of revenue recognition, billings, and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the Condensed Consolidated Balance Sheets. In our Air Pollution Control (APC) technology segment, amounts are billed as work progresses&#160;in accordance with agreed-upon contractual terms. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. For the FUEL CHEM technology segment, deliveries made in the current period but billed in subsequent periods are also considered unbilled receivables (contract assets).&#160;These assets are reported on the&#160;Condensed Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period.&#160;At <em style="font: inherit;"> June 30, 2022</em>,&#160;<em style="font: inherit;"> December 31, 2021</em>, and <em style="font: inherit;"> December 31, 2020, </em>contract assets for APC technology projects were approximately $1,106,&#160;$1,277, and $2,079, respectively, and at <em style="font: inherit;"> December 31, 2020, </em>contract assets for the FUEL CHEM technology segment were approximately $269, and&#160;are included in accounts receivable on the Condensed Consolidated Balance Sheets. There were no contract assets for the FUEL CHEM technology segment as of&#160;<em style="font: inherit;"> June 30, 2022</em>&#160;or&#160;<em style="font: inherit;"> December 31, 2021</em>.&#160;&#160;</p>

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">However, the Company will periodically bill in advance of costs incurred before revenue is recognized, resulting in contract liabilities. These liabilities are reported on the&#160;Condensed Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period. Contract liabilities were $578,&#160;$390, and $850 at <em style="font: inherit;"> June 30, 2022</em>,&#160;<em style="font: inherit;"> December 31, 2021</em>, and <em style="font: inherit;"> December 31, 2020, </em>respectively, and are included in other accrued liabilities on the&#160;Condensed Consolidated Balance Sheets.</p>
   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&#160;</p>
   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Changes in the contract asset and liability balances during the&#160;<em style="font: inherit;">six</em> month period ended <em style="font: inherit;"> June 30, 2022</em>, were <em style="font: inherit;">not</em> materially impacted by any other items other than amounts billed and revenue recognized as described previously. Revenue recognized that was included in the contract liability balance at the beginning of the period was $20&#160;and $250&#160;for the <em style="font: inherit;">three</em> and <em style="font: inherit;">six</em> months ended <em style="font: inherit;"> June 30, 2022</em>, respectively, and $49 and $157&#160;for <em style="font: inherit;">three</em> and <em style="font: inherit;">six</em> months ended <em style="font: inherit;"> June 30, 2021</em>, respectively, which represented primarily revenue from progress towards completion of our APC technology contracts.</p>

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Stock options granted to employees under the Incentive Plans have a 10-year life and they vest as follows: 50% after the <em style="font: inherit;">second</em> anniversary of the award date, 25% after the <em style="font: inherit;">third</em> anniversary, and the final 25% after the <em style="font: inherit;">fourth</em> anniversary of the award date. Fuel Tech calculates stock compensation expense for employee option awards based on the grant date fair value of the award, less expected annual forfeitures, and recognizes expense on a straight-line basis over the <em style="font: inherit;">four</em>-year service period of the award. Stock options granted to members of our board of directors vest immediately. Stock compensation for these awards is based on the grant date fair value of the award and is recognized in expense immediately.</p>

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Fuel Tech uses the Black-Scholes option pricing model to estimate the grant date fair value of employee stock options. The principal variable assumptions utilized in valuing options and the methodology for estimating such model inputs include: (<em style="font: inherit;">1</em>)&#160;risk-free interest rate &#8211; an estimate based on the yield of zero&#8211;coupon treasury securities with a maturity equal to the expected life of the option; (<em style="font: inherit;">2</em>)&#160;expected volatility &#8211; an estimate based on the historical volatility of Fuel Tech&#8217;s Common Stock for a period equal to the expected life of the option; and (<em style="font: inherit;">3</em>)&#160;expected life of the option &#8211; an estimate based on historical experience including the effect of employee terminations.</p>

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Fuel Tech is subject to various claims and contingencies related to, among other things, workers compensation, general liability (including product liability), and lawsuits. The Company records liabilities where a contingent loss is probable and can be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when <em style="font: inherit;">no</em> amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is <em style="font: inherit;">not</em> probable or the amount is <em style="font: inherit;">not</em> estimable, or both, if there is a reasonable possibility that a material loss <em style="font: inherit;"> may </em>have been incurred.</p>

   <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify;">From time to time we are involved in litigation with respect to matters arising from the ordinary conduct of our business. In the opinion of management, based upon presently available information, either adequate provision for anticipated costs have been accrued or the ultimate anticipated costs will <em style="font: inherit;">not</em> materially affect our consolidated financial position, results of operations, or cash flows.&#160;We do <em style="font: inherit;">not</em> believe we have any pending loss contingencies that are probable or reasonably possible of having a material impact on our consolidated financial position, results of operations or cash flows.</p>
   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&#160;</p>
   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">Fuel Tech issues a standard product warranty with the sale of its products to customers. Our recognition of warranty liability is based primarily on analyses of warranty claims experienced in the preceding years as the nature of our historical product sales for which we offer a warranty are substantially unchanged. This approach provides an aggregate warranty accrual that is historically aligned with actual warranty claims experienced.</p>
   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&#160;</p>
   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">There was no change in the warranty liability balance included in the other accrued liabilities line of the Condensed Consolidated Balance Sheets during the <em style="font: inherit;">six</em> months ended <em style="font: inherit;"> June 30, 2022 </em>and <em style="font: inherit;">2021</em>.

At <em style="font: inherit;"> June 30, 2022, </em>$10,000 was invested in a money market fund with the intent to purchase debt securities in the near term. A portion of the funds invested are restricted as collateral under the Investment Collateral Security agreement (see Note <em style="font: inherit;">10</em>).&#160;</span></p>

   <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0px; text-align: justify;"><span style="background-color:#ffffff;">We consider all highly liquid debt investments with original maturities from the date of purchase of <em style="font: inherit;">three</em> months or less as cash equivalents. Cash equivalents include investments in money market funds.

The Company has the positive intent and ability to hold these investments to maturity and does&#160;<em style="font: inherit;">not</em> expect&#160;to sell any debt securities before maturity to settle an obligation under the Investment Collateral Security agreement. The maturities of our HTM investments range from 3 to 36 months. HTM debt investments with original maturities of approximately <em style="font: inherit;">three</em> months or less from the date of purchase are classified within cash and cash equivalents. HTM debt investments with original maturities at the date of purchase greater than approximately <em style="font: inherit;">three</em> months and remaining maturities of less than <em style="font: inherit;">one</em> year are classified as short-term investments. HTM debt investments with remaining maturities beyond <em style="font: inherit;">one</em> year are classified as other long-term investments. Interest income, including amortization of premium and accretion of discount, are included on the Condensed Consolidated Statements of Operations in Interest income under the effective yield method.&#160;Discounts or premiums are included in the effective yield and amortized on a straight-line until maturity.</span></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>

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;The Company&#x2019;s nitrogen oxide (NOx) reduction technologies reduce nitrogen oxide emissions from boilers, furnaces, and other stationary combustion sources.&#160;To reduce NOx emissions, our technologies utilize advanced combustion modification techniques and post-combustion NOx control approaches including non-catalytic, catalytic, and combined systems.&#160;The Company also&#160;provides solutions for the mitigation of particulate matter, including particulate control with electrostatic precipitator products and services, and using flue gas conditioning systems which modify the ash properties of particulate for improved collection efficiency. The Company&#x2019;s FUEL CHEM&#xae; technology improves the efficiency, reliability, fuel flexibility, boiler heat rate, and environmental status of combustion units by controlling slagging, fouling, corrosion, and opacity. Water treatment technologies include DGI&#x2122; Dissolved Gas Infusion Systems which utilize a patented nozzle to deliver supersaturated oxygen solutions and other gas-water combinations to target process applications or environmental issues. This infusion process has a variety of applications in the water and wastewater industries, including remediation, aeration, biological treatment, and wastewater odor management.&lt;/p&gt;

At &lt;em style="font: inherit;"&gt; June 30, 2022, &lt;/em&gt;$10,000 was invested in a money market fund with the intent to purchase debt securities in the near term. A portion of the funds invested are restricted as collateral under the Investment Collateral Security agreement (see Note &lt;em style="font: inherit;"&gt;10&lt;/em&gt;).&#160;&lt;/span&gt;&lt;/p&gt;

Cash equivalents include investments in money market funds. Carrying value of cash equivalents approximates fair value due to the maturities of &lt;em style="font: inherit;"&gt;3&lt;/em&gt; months or less.&lt;/span&gt;&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;&#160;&lt;/p&gt;

The Company has the positive intent and ability to hold these investments to maturity and does&#160;&lt;em style="font: inherit;"&gt;not&lt;/em&gt; expect&#160;to sell any debt securities before maturity to settle an obligation under the Investment Collateral Security agreement. The maturities of our HTM investments range from 3 to 36 months. HTM debt investments with original maturities of approximately &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months or less from the date of purchase are classified within cash and cash equivalents. HTM debt investments with original maturities at the date of purchase greater than approximately &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months and remaining maturities of less than &lt;em style="font: inherit;"&gt;one&lt;/em&gt; year are classified as short-term investments. HTM debt investments with remaining maturities beyond &lt;em style="font: inherit;"&gt;one&lt;/em&gt; year are classified as other long-term investments. Interest income, including amortization of premium and accretion of discount, are included on the Condensed Consolidated Statements of Operations in Interest income under the effective yield method.&#160;Discounts or premiums are included in the effective yield and amortized on a straight-line until maturity.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;&lt;span style="background-color:#ffffff;"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"/&gt;

Usage is recorded in cost of sales in the period that parts were issued to a project,&#160;used to service equipment, or sold to customers. In&lt;/span&gt;ventories are periodically evaluated to identify obsolete or otherwise impaired parts and are written off when management determines usage is &lt;em style="font: inherit;"&gt;not&lt;/em&gt; probable. The Company estimates the balance of excess and obsolete inventory by analyzing inventory by age using last used and original purchase date and existing sales pipeline for which the inventory could be used.&lt;/p&gt;&lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;&#160;&lt;/p&gt;

At &lt;em style="font: inherit;"&gt; June 30, 2022, &lt;/em&gt;$10,000 was invested in a money market fund with the intent to purchase debt securities in the near term. A portion of the funds invested are restricted as collateral under the Investment Collateral Security agreement (see Note &lt;em style="font: inherit;"&gt;10&lt;/em&gt;).&#160;&lt;/span&gt;&lt;/p&gt;

Cash equivalents include investments in money market funds. Carrying value of cash equivalents approximates fair value due to the maturities of &lt;em style="font: inherit;"&gt;3&lt;/em&gt; months or less.&lt;/span&gt;&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;&#160;&lt;/p&gt;

The Company has the positive intent and ability to hold these investments to maturity and does&#160;&lt;em style="font: inherit;"&gt;not&lt;/em&gt; expect&#160;to sell any debt securities before maturity to settle an obligation under the Investment Collateral Security agreement. The maturities of our HTM investments range from 3 to 36 months. HTM debt investments with original maturities of approximately &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months or less from the date of purchase are classified within cash and cash equivalents. HTM debt investments with original maturities at the date of purchase greater than approximately &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months and remaining maturities of less than &lt;em style="font: inherit;"&gt;one&lt;/em&gt; year are classified as short-term investments. HTM debt investments with remaining maturities beyond &lt;em style="font: inherit;"&gt;one&lt;/em&gt; year are classified as other long-term investments. Interest income, including amortization of premium and accretion of discount, are included on the Condensed Consolidated Statements of Operations in Interest income under the effective yield method.&#160;Discounts or premiums are included in the effective yield and amortized on a straight-line until maturity.&lt;/span&gt;&lt;/p&gt;</us-gaap:InvestmentPolicyTextBlock>

Usage is recorded in cost of sales in the period that parts were issued to a project,&#160;used to service equipment, or sold to customers. In&lt;/span&gt;ventories are periodically evaluated to identify obsolete or otherwise impaired parts and are written off when management determines usage is &lt;em style="font: inherit;"&gt;not&lt;/em&gt; probable. The Company estimates the balance of excess and obsolete inventory by analyzing inventory by age using last used and original purchase date and existing sales pipeline for which the inventory could be used.&lt;/p&gt;</us-gaap:InventoryPolicyTextBlock>

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&lt;i&gt;Contract Balances&lt;/i&gt;&lt;/p&gt;
   &lt;p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;The timing of revenue recognition, billings, and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the Condensed Consolidated Balance Sheets. In our Air Pollution Control (APC) technology segment, amounts are billed as work progresses&#160;in accordance with agreed-upon contractual terms. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. For the FUEL CHEM technology segment, deliveries made in the current period but billed in subsequent periods are also considered unbilled receivables (contract assets).&#160;These assets are reported on the&#160;Condensed Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period.&#160;At &lt;em style="font: inherit;"&gt; June 30, 2022&lt;/em&gt;,&#160;&lt;em style="font: inherit;"&gt; December 31, 2021&lt;/em&gt;, and &lt;em style="font: inherit;"&gt; December 31, 2020, &lt;/em&gt;contract assets for APC technology projects were approximately $1,106,&#160;$1,277, and $2,079, respectively, and at &lt;em style="font: inherit;"&gt; December 31, 2020, &lt;/em&gt;contract assets for the FUEL CHEM technology segment were approximately $269, and&#160;are included in accounts receivable on the Condensed Consolidated Balance Sheets. There were no contract assets for the FUEL CHEM technology segment as of&#160;&lt;em style="font: inherit;"&gt; June 30, 2022&lt;/em&gt;&#160;or&#160;&lt;em style="font: inherit;"&gt; December 31, 2021&lt;/em&gt;.&#160;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;However, the Company will periodically bill in advance of costs incurred before revenue is recognized, resulting in contract liabilities. These liabilities are reported on the&#160;Condensed Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period. Contract liabilities were $578,&#160;$390, and $850 at &lt;em style="font: inherit;"&gt; June 30, 2022&lt;/em&gt;,&#160;&lt;em style="font: inherit;"&gt; December 31, 2021&lt;/em&gt;, and &lt;em style="font: inherit;"&gt; December 31, 2020, &lt;/em&gt;respectively, and are included in other accrued liabilities on the&#160;Condensed Consolidated Balance Sheets.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Changes in the contract asset and liability balances during the&#160;&lt;em style="font: inherit;"&gt;six&lt;/em&gt; month period ended &lt;em style="font: inherit;"&gt; June 30, 2022&lt;/em&gt;, were &lt;em style="font: inherit;"&gt;not&lt;/em&gt; materially impacted by any other items other than amounts billed and revenue recognized as described previously. Revenue recognized that was included in the contract liability balance at the beginning of the period was $20&#160;and $250&#160;for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; and &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; June 30, 2022&lt;/em&gt;, respectively, and $49 and $157&#160;for &lt;em style="font: inherit;"&gt;three&lt;/em&gt; and &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; June 30, 2021&lt;/em&gt;, respectively, which represented primarily revenue from progress towards completion of our APC technology contracts.&lt;/p&gt;
   &lt;p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&#160;&lt;/p&gt;

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Remaining performance obligations represents the transaction price of APC technology booked orders for which work has &lt;em style="font: inherit;"&gt;not&lt;/em&gt; been performed.&lt;span style="background-color:#ffffff;"&gt; As of &lt;/span&gt;&lt;em style="font: inherit;"&gt; June 30, 2022&lt;/em&gt;&lt;span style="background-color:#ffffff;"&gt;, the aggregate amount of the transaction price allocated to remaining performance obligations was $&lt;/span&gt;10,547&lt;span style="background-color:#ffffff;"&gt;. The Company expects to recognize revenue on approximately $&lt;/span&gt;8,414&lt;span style="background-color:#ffffff;"&gt;&#160;of the remaining performance obligations over the next 12 months with the remaining recognized thereafter.&#160;&lt;/span&gt;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/p&gt;

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Under our stock-based employee compensation plan, referred to as the Fuel Tech, Inc. &lt;em style="font: inherit;"&gt;2014&lt;/em&gt; Long-Term Incentive Plan (Incentive Plan), awards &lt;em style="font: inherit;"&gt; may &lt;/em&gt;be granted to participants in the form of Non-Qualified Stock Options, Incentive Stock Options, Stock Appreciation Rights, Restricted Stock, RSUs, Performance Awards, Bonuses or other forms of share-based or non-share-based awards or combinations thereof. Participants in the Incentive Plan &lt;em style="font: inherit;"&gt; may &lt;/em&gt;be our directors, officers, employees, consultants, or advisors (except consultants or advisors in capital-raising transactions) as the directors determine are key to the success of our business. There are a maximum of 5,600,676&#160;shares that &lt;em style="font: inherit;"&gt; may &lt;/em&gt;be issued or reserved for awards to participants under the Incentive Plan. As of &lt;em style="font: inherit;"&gt; June 30, 2022&lt;/em&gt;, Fuel Tech had 1,809,250&#160;shares available for share-based awards under the Incentive&#160;Plan.&lt;/p&gt;

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Stock-based compensation is included in selling, general, and administrative costs in our Condensed Consolidated Statements of Operations.

   &lt;p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Stock options granted to employees under the Incentive Plans have a 10-year life and they vest as follows: 50% after the &lt;em style="font: inherit;"&gt;second&lt;/em&gt; anniversary of the award date, 25% after the &lt;em style="font: inherit;"&gt;third&lt;/em&gt; anniversary, and the final 25% after the &lt;em style="font: inherit;"&gt;fourth&lt;/em&gt; anniversary of the award date. Fuel Tech calculates stock compensation expense for employee option awards based on the grant date fair value of the award, less expected annual forfeitures, and recognizes expense on a straight-line basis over the &lt;em style="font: inherit;"&gt;four&lt;/em&gt;-year service period of the award. Stock options granted to members of our board of directors vest immediately. Stock compensation for these awards is based on the grant date fair value of the award and is recognized in expense immediately.&lt;/p&gt;
   &lt;p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Fuel Tech uses the Black-Scholes option pricing model to estimate the grant date fair value of employee stock options. The principal variable assumptions utilized in valuing options and the methodology for estimating such model inputs include: (&lt;em style="font: inherit;"&gt;1&lt;/em&gt;)&#160;risk-free interest rate &#x2013; an estimate based on the yield of zero&#x2013;coupon treasury securities with a maturity equal to the expected life of the option; (&lt;em style="font: inherit;"&gt;2&lt;/em&gt;)&#160;expected volatility &#x2013; an estimate based on the historical volatility of Fuel Tech&#x2019;s Common Stock for a period equal to the expected life of the option; and (&lt;em style="font: inherit;"&gt;3&lt;/em&gt;)&#160;expected life of the option &#x2013; an estimate based on historical experience including the effect of employee terminations.&lt;/p&gt;

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;In addition to the Incentive Plans, Fuel Tech has a Deferred Compensation Plan for Directors (Deferred Plan). Under the terms of the Deferred Plan, Directors can elect to defer Directors&#x2019; fees for shares of Fuel Tech Common Stock that are issuable at a future date as defined in the agreement. In accordance with &lt;span style="background-color:#ffffff"&gt;Accounting Standards Codification (ASC)&#160;&lt;/span&gt;&lt;em style="font: inherit;"&gt;718,&lt;/em&gt; Fuel Tech accounts for these awards as equity awards as opposed to liability awards.

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Fuel Tech is subject to various claims and contingencies related to, among other things, workers compensation, general liability (including product liability), and lawsuits. The Company records liabilities where a contingent loss is probable and can be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when &lt;em style="font: inherit;"&gt;no&lt;/em&gt; amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is &lt;em style="font: inherit;"&gt;not&lt;/em&gt; probable or the amount is &lt;em style="font: inherit;"&gt;not&lt;/em&gt; estimable, or both, if there is a reasonable possibility that a material loss &lt;em style="font: inherit;"&gt; may &lt;/em&gt;have been incurred.&lt;/p&gt;
   &lt;p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify;"&gt;From time to time we are involved in litigation with respect to matters arising from the ordinary conduct of our business. In the opinion of management, based upon presently available information, either adequate provision for anticipated costs have been accrued or the ultimate anticipated costs will &lt;em style="font: inherit;"&gt;not&lt;/em&gt; materially affect our consolidated financial position, results of operations, or cash flows.&#160;We do &lt;em style="font: inherit;"&gt;not&lt;/em&gt; believe we have any pending loss contingencies that are probable or reasonably possible of having a material impact on our consolidated financial position, results of operations or cash flows.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;Fuel Tech issues a standard product warranty with the sale of its products to customers. Our recognition of warranty liability is based primarily on analyses of warranty claims experienced in the preceding years as the nature of our historical product sales for which we offer a warranty are substantially unchanged. This approach provides an aggregate warranty accrual that is historically aligned with actual warranty claims experienced.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;There was no change in the warranty liability balance included in the other accrued liabilities line of the Condensed Consolidated Balance Sheets during the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; June 30, 2022 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2021&lt;/em&gt;. The warranty liability balance was $159 at &lt;em style="font: inherit;"&gt; June 30, 2022&lt;/em&gt; and &lt;em style="font: inherit;"&gt; December 31, &lt;/em&gt;&lt;em style="font: inherit;"&gt;2021&lt;/em&gt;.&lt;/p&gt;

   &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;The Company&#x2019;s effective tax rate is approximately 0.7%&lt;span style="background-color:#ffffff;"&gt;&#160;and&#160;&lt;/span&gt;2.6%&lt;span style="background-color:#ffffff;"&gt; for the &lt;/span&gt;&lt;em style="font: inherit;"&gt;six&lt;/em&gt;&lt;span style="background-color:#ffffff;"&gt;&#160;month periods ended &lt;/span&gt;&lt;em style="font: inherit;"&gt; June 30, 2022 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2021&lt;/em&gt;, respectively. The Company's effective tax rate differs from the statutory federal tax rate of 21% for the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; month periods ended &lt;em style="font: inherit;"&gt; June 30, 2022 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; primarily due to a full valuation allowance recorded on our United States, China and Italy deferred tax assets since we cannot anticipate when or if we will have sufficient taxable income to utilize the deferred tax assets in the future. Further, our effective tax rate differs from the statutory federal tax rate due to state taxes, differences between U.S. and foreign tax rates, foreign losses incurred with &lt;em style="font: inherit;"&gt;no&lt;/em&gt; related tax benefit, non-deductible commissions, and non-deductible meals and entertainment expenses for the &lt;em style="font: inherit;"&gt;six&lt;/em&gt; month periods ended &lt;em style="font: inherit;"&gt; June 30, 2022 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2021&lt;/em&gt;.&lt;span style="background-color:#ffffff;"&gt;&#160;Income generated in the &lt;/span&gt;&lt;em style="font: inherit;"&gt;six&lt;/em&gt;&lt;span style="background-color:#ffffff;"&gt;&#160;months ended &lt;em style="font: inherit;"&gt; June 30, 2021&#160;&lt;/em&gt;attributed to the gain on forgiveness of the Paycheck Protection Plan loan is&#160;tax exempt.&#160;&lt;/span&gt;&lt;/p&gt;
