FUEL TECH, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
March 31, 2019
(Unaudited)
(in thousands, except share and per-share data)
1. General
Organization
Fuel Tech, Inc. and subsidiaries ("Fuel Tech", the "Company", "we", "us" or "our") provides advanced engineered solutions for the optimization of combustion systems in utility and industrial applications. Our primary focus is on the worldwide marketing and sale of NO x reduction technologies as well as our FUEL CHEM program. The Company’s NO x reduction technologies reduce nitrogen oxide emissions from boilers, furnaces and other stationary combustion sources.
Our FUEL CHEM program is based on proprietary TIFI® Targeted In-Furnace™ Injection technology, in combination with advanced Computational Fluid Dynamics (CFD) and Chemical Kinetics Modeling (CKM) boiler modeling, in the unique application of specialty chemicals to improve the efficiency, reliability and environmental status of combustion units by controlling slagging, fouling, corrosion, opacity and other sulfur trioxide-related issues in the boiler.
Our business is materially dependent on the continued existence and enforcement of air quality regulations, particularly in the United States. We have expended significant resources in the research and development of new technologies in building our proprietary portfolio of air pollution control, fuel and boiler treatment chemicals, computer modeling and advanced visualization technologies.
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Exchange Act. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the financial statements reflect all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the statements for the periods presented. All significant intercompany transactions and balances have been eliminated. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results to be expected for the full year ending December 31, 2019. For further information, refer to the audited consolidated financial statements and footnotes thereto included in Fuel Tech’s Annual Report on Form 10-K for the year ended December 31, 2018 as filed with the Securities and Exchange Commission.
2. Summary of Significant Accounting Policies
Restricted cash
Restricted cash represents funds that are restricted to satisfy any amount borrowed against the Company's existing revolving credit facility (the Facility) with JPMorgan Chase Bank, N.A. The balance of restricted cash totaling $6,020 will remain through the Maturity Date of the Facility. Refer to Note 10 Debt Financing for further information on the Facility.
The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Consolidated Balance Sheet that sum to the total of the same such amounts shown in the Consolidated Statements of Cash Flows:

| March 31, 2019 | March 31, 2018
Cash and cash equivalents | $ | 7,135 |  | $ | 5,667 |
Restricted cash included in current assets | 6,020 |  | 1,520 |
Restricted cash included in long-term assets | — |  | 5,000 |
Total cash, cash equivalents, and restricted cash shown in the Consolidated Statements of Cash Flows | $ | 13,155 |  | $ | 12,187 |

Leases
On January 1, 2019, we adopted ASC 842 using the modified retrospective method outlined in ASU 2018-11, “Leases (Topic 842) Targeted Improvements.” Refer to Note 12 for further details regarding the effect of adoption. We determine if an arrangement is a lease at inception. Operating leases are included in right-of-use ("ROU") operating lease assets, operating lease liabilities - current, and operating lease liabilities - non-current on our Consolidated Balance Sheets.
Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.
We have lease agreements with lease and non-lease components, which we elected the practical expedient to not separate lease and non-lease components for the majority of our leases. For certain equipment leases, such as vehicles, we account for the lease and non-lease components as a single lease component. We also elected the practical expedient to keep leases with an initial term of 12 months or less off of the consolidated balance sheet.
3. Revenue
The Company recognizes revenue when control of the promised goods or services is transferred to our customers, in amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Fuel Tech’s sales of products to customers represent single performance obligations. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue.
We generally expense sales commissions on a ratable basis when incurred because the amortization period would have been one year or less. These costs are recorded within selling, general and administrative expenses within the Condensed Consolidated Statements of Operations.
FUEL CHEM
Revenues from the sale of chemical products are recognized when control transfers to customer upon shipment or delivery of the product based on the applicable shipping terms. We generally recognize revenue for these arrangements at a point in time based on our evaluation of when the customer obtains control of the promised goods or services.
Air Pollution Control Technology
Fuel Tech’s APC contracts are typically six to eighteen months in length. A typical contract will have three or four critical operational measurements that, when achieved, serve as the basis for us to invoice the customer via progress billings. At a minimum, these measurements will include the generation of engineering drawings, the shipment of equipment and the completion of a system performance test.
As part of most of its contractual APC project agreements, Fuel Tech will agree to customer-specific acceptance criteria that relate to the operational performance of the system that is being sold. These criteria are determined based on modeling that is performed by Fuel Tech personnel, which is based on operational inputs that are provided by the customer. The customer will warrant that these operational inputs are accurate as they are specified in the binding contractual agreement. Further, the customer is solely responsible for the accuracy of the operating condition information; typically all performance guarantees and equipment warranties granted by us are voidable if the operating condition information is inaccurate or is not met.
7

Since control transfers over time, revenue is recognized based on the extent of progress towards completion of the single performance obligation. Fuel Tech uses the cost-to-cost input measure of progress for our contracts since it best depicts the transfer of assets to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost input measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred. Costs to fulfill include all internal and external engineering costs, equipment charges, inbound and outbound freight expenses, internal and site transfer costs, installation charges, purchasing and receiving costs, inspection costs, warehousing costs, project personnel travel expenses and other direct and indirect expenses specifically identified as project- or product-line related, as appropriate (e.g. test equipment depreciation and certain insurance expenses).
Fuel Tech has installed over 1,000 units with APC technology and normally provides performance guarantees to our customers based on the operating conditions for the project. As part of the project implementation process, we perform system start-up and optimization services that effectively serve as a test of actual project performance. We believe that this test, combined with the accuracy of the modeling that is performed, enables revenue to be recognized prior to the receipt of formal customer acceptance.

Timing of Revenue Recognition
The following table presents the timing of our revenue recognition:

| Three Months Ended March 31,
| 2019 | 2018
Products transferred at a point in time | 5,414 |  | 5,069 |
Products and services transferred over time | 4,741 |  | 7,722 |
Total Revenues | 10,155 |  | 12,791 |

Contract Balances
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 consolidated balance sheets. In our Air Pollution Control Technology segment, amounts are billed as work progresses in accordance with agreed-upon contractual terms. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. These assets are reported on the consolidated balance sheet on a contract-by-contract basis at the end of each reporting period. At March 31, 2019 and December 31, 2018, contract assets were approximately $6,736 and $5,540, respectively, and are included in accounts receivable on the consolidated balance sheets.
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 consolidated balance sheet on a contract-by-contract basis at the end of each reporting period. Contract liabilities were $902 and $1,234, at March 31, 2019 and December 31, 2018, respectively, and are included in other accrued liabilities on the consolidated balance sheets.
Changes in the contract asset and liability balances during the three month period ended March 31, 2019, were not materially impacted by any other items other than amounts billed and revenue recognized as described previously. During the three months ended March 31, 2019, revenue recognized that was included in the contract liability balance at the beginning of the period was $224, which represented primarily revenue from progress towards completion of our Air Pollution Control technology contracts. During the three m onths ended March 31, 2018, revenue recognized that was included in the contract liability balance at the beginning of the period was $1,942 and represented primarily revenue from progress towards completion of our Air Pollution Control technology contracts.
As of March 31, 2019, we had six construction contracts in progress that were identified as loss contracts and a provision for losses of $124 was recorded in other accrued liabilities on the consolidated balance sheet. Refer to Footnote 14 for an accrual related to certain non-conformance issues with a U.S. customer associated with equipment that requires remedy under the warranty provision of the customer contract. As of December 31, 2018, we had five construction contracts in progress that were identified as loss contracts and a provision for losses in the amount of $123 was recorded in other accrued liabilities on the consolidated balance sheet.
Remaining Performance Obligations
Remaining performance obligations, represents the transaction price of Air Pollution Control technology booked orders for which work has not been performed. As of March 31, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was $12,219. The Company expects to recognize revenue on approximately $11,892 of the remaining performance obligations over the next 12 months with the remaining recognized thereafter.
4. Discontinued Operations
During the second quarter of 2017, the Company suspended all operations associated with the Fuel Conversion business segment. The components of the net assets of the Fuel Conversion discontinued operations are Assets held for sale (which consists primarily of certain equipment) on the Consolidated Balance Sheets totaling $413 and $485 as of March 31, 2019 and December 31, 2018, respectively. The Company sold certain equipment within Assets held for sale for the three-month periods ended March 31, 2019 of $55. Additionally, the Company entered into an agreement with a potential buyer for the remaining equipment within Assets held for sale which provided a non-refundable deposit of $20 for the option to purchase for $500 (less applicable commission to the third party equipment reseller) by May 21, 2019 or withdraw without any further obligation.
In addition, accrued severance of $35 and $65 is included in the other accrued liabilities line of the Consolidated Balance Sheets as of March 31, 2019 and December 31, 2018, respectively. A total of $30 was paid for the three-months ended March 31, 2019, $30 will be paid in the second quarter of 2019 and the remaining $5 will be paid in the third quarter of 2019.
The Fuel Conversion business segment had no other assets or liabilities associated with it.
The activity of the Fuel Conversion discontinued operations consisted primarily of storage costs for the certain equipment held in Assets held for sale of $10 and $25 for the three-month periods ended March 31, 2019 and 2018, respectively. The Fuel Conversion business segment had no revenues associated with it.
5. Restructuring Activities
On January 18, 2019, the Company announced a planned suspension of its Air Pollution Control (“APC”) business operation in China (“Beijing Fuel Tech”). This action is part of Fuel Tech’s ongoing operational improvement initiatives designed to prioritize resource allocation, reduce costs, and drive profitability for the Company on a global basis. The transition associated with the suspension of the APC business is underway, and includes staff rationalization, supplier and partner engagement, and the monetization of certain assets. The Company expects to complete the process during the second half of 2019.
The following table presents our revenues and net loss in China for the three month periods ended March 31, 2019 and 2018:

| 2019 | 2018
Total revenues | $ | 338 |  | $ | 659 |
Net loss | (850 | ) | (533 | )

The following table presents net assets in China for the three months ended March 31, 2019 and 2018:

| 2019 | 2018
Total assets | $ | 7,719 |  | $ | 12,126 |
Total liabilities | (2,809 | ) | (4,642 | )
Total net assets | 4,910 |  | 7,484 |

Total assets primarily consist of accounts receivable, contract assets, inventory, prepaid expenses and property, plant and equipment. Total liabilities consist of accounts payable and certain accrued liabilities.
The Company expects to incur approximately $632 of severance costs relating to the suspension of the APC business in China, of which $257 was paid for the three months ended March 31, 2019 and $375 are expected to be paid in the second quarter of 2019.
On January 23, 2019, the Company notified the landlord of our intention to early terminate the lease on July 22, 2019. The Company incurred an early termination penalty of $63, which is included in restructuring expense and other accrued liabilities for the three months ended March 31, 2019. The Company expects to incur other disposal costs including contractual termination payments or other miscellaneous expenses but an estimated amount or range of amounts has not yet been determined.

The Company recorded restructuring charges of $595 and $0 for the three months ended March 31, 2019 and 2018, respectively. The charge consisted primarily of one-time severance costs of $532 and the early termination penalty for our lease associated with the suspension of our APC business in China of $63. The following is a reconciliation of the accrual for the workforce reduction that is included within the "Accrued Liabilities - Employee Compensation" line of the consolidated balance sheets for the three months ending March 31, 2019 and 2018:

7. Treasury Stock
Common stock held in treasury totaled 656,844 and 655,306 with a cost of $1,486 and $1,484 at March 31, 2019 and December 31, 2018, respectively. These shares were withheld from employees to settle personal tax withholding obligations that arose as a result of restricted stock units that vested in the periods presented.
8. Earnings per Share
Basic earnings per share excludes the dilutive effects of stock options, restricted stock units (RSUs), and the nil coupon non-redeemable convertible unsecured loan notes. Diluted earnings per share includes the dilutive effect of the nil coupon non-redeemable convertible unsecured loan notes, RSUs, and unexercised in-the-money stock options, except in periods of net loss where the effect of these instruments is anti-dilutive. Out-of-money stock options are excluded from diluted earnings per share because they are anti-dilutive. For the three months ended March 31, 2019 and 2018, basic earnings per share is equal to diluted earnings per share because all outstanding stock awards and convertible loan notes are considered anti-dilutive during periods of net loss. The following table sets forth the weighted-average shares used in calculating the earnings per share for the months ended March 31, 2019 and 2018.

| Three Months Ended March 31,
| 2019 | 2018
Basic weighted-average shares | 24,177,000 |  | 24,146,000 |
Conversion of unsecured loan notes | — |  | — |
Unexercised options and unvested RSUs | — |  | — |
Diluted weighted-average shares | 24,177,000 |  | 24,146,000 |

Fuel Tech had 1,280,000 and 1,318,000 weighted average equity awards outstanding at March 31, 2019 and 2018, respectively, that were not dilutive for the purposes of inclusion in the calculation of diluted earnings per share but could potentially become dilutive in future periods.
9. Stock-Based Compensation
Under our stock-based employee compensation plan, referred to as the Fuel Tech, Inc. 2014 Long-Term Incentive Plan (Incentive Plan), awards may be granted to participants in the form of Non-Qualified Stock Options, Incentive Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units (“RSUs”), Performance Awards, Bonuses or other forms of share-based or non-share-based awards or combinations thereof. Participants in the Incentive Plan may 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 shares that may be issued or reserved for awards to participants under the Incentive Plan. As of March 31, 2019, Fuel Tech had 1,970,271 shares available for share-based awards under the 2014 Plan.
We did not record any excess tax benefits within income tax expense for the three months ended March 31, 2019. Given the Company has a full valuation allowance on its deferred tax assets, there were no excess tax benefits to record for the three months ended March 31, 2019. In addition, we account for forfeitures of awards based on an estimate of the number of awards expected to be forfeited and adjusting the estimate when it is no longer probable that the employee will fulfill the service condition.
Stock-based compensation is included in selling, general, and administrative costs in our Consolidated Statements of Operations. The components of stock-based compensation for the three months ended March 31, 2019 and 2018 were as follows:

| Three Months Ended March 31,
| 2019 | 2018
Stock options and restricted stock units, net of forfeited | $ | 96 |  | $ | (59 | )
Tax benefit of stock-based compensation expense | — |  | — |
After-tax effect of stock-based compensation | $ | 96 |  | $ | (59 | )

Stock Options
Stock options granted to employees under the Incentive Plans have a 10-year life and they vest as follows: 50% after the second anniversary of the award date, 25% after the third anniversary, and the final 25% after the fourth 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
11

expected annual forfeitures, and recognizes expense on a straight-line basis over the four-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.
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: (1) risk-free interest rate – an estimate based on the yield of zero–coupon treasury securities with a maturity equal to the expected life of the option; (2) expected volatility – an estimate based on the historical volatility of Fuel Tech’s Common Stock for a period equal to the expected life of the option; and (3) expected life of the option – an estimate based on historical experience including the effect of employee terminations.
Stock option activity for Fuel Tech’s Incentive Plans for the three months ended March 31, 2019 was as follows:

| Number of Options | Weighted- Average Exercise Price | Weighted- Average Remaining Contractual Term | Aggregate Intrinsic Value
Outstanding on January 1, 2019 | 932,500 |  | $ | 4.68 |  |  |
Granted | — |  | — |  |  |
Exercised | — |  | — |  |  |
Expired or forfeited | — |  | — |  |  |
Outstanding on March 31, 2019 | 932,500 |  | $ | 4.68 |  | 4.42 | $ | 131 |
Exercisable on March 31, 2019 | 932,500 |  | $ | 4.68 |  | 4.42 | $ | 131 |

As of March 31, 2019, there was no unrecognized compensation cost related to non-vested stock options granted under the Incentive Plans.
Restricted Stock Units
Restricted stock units (RSUs) granted to employees vest over time based on continued service (typically vesting over a period between two and four years). Such time-vested RSUs are valued at the date of grant using the intrinsic value method based on the closing price of the Common Shares on the grant date. Compensation cost, adjusted for estimated forfeitures, is amortized on a straight-line basis over the requisite service period.
In addition to the time vested RSUs, the Company entered into a 2019 Executive Performance RSU Award Agreement (the “2019 Agreement”) with certain officers, including its President and Chief Executive Officer and Principal Financial Officer and Controller pursuant to which each 2019 Participating Executive will have the opportunity to earn a specified amount of restricted stock units (RSUs). The amount of RSUs awarded, if any, will be based on the Company’s achievement of varying levels of operating income before the impact of incentive pay (but including adjustments to reflect the payment of sales commissions) in fiscal 2019 (“Operating Income”), as determined by the Company, in its sole discretion. Nevertheless, no Participating Executive will be entitled to any such RSUs unless the Company achieves a minimum of $2 million in Operating Income in 2019. If awarded, such RSUs will vest in equal amounts (i.e., 1/3, 1/3 and 1/3) over three years commencing one year after the grant date based on continued service. Such RSUs are valued at the date of grant using the intrinsic value method based on the closing price of the Company’s common stock on the grant date.
At March 31, 2019, there is $657 of unrecognized compensation cost related to all non-vested share-based compensation arrangements granted under the Incentive Plan. That cost is expected to be recognized over the remaining requisite service period of 1.93 years.
A summary of restricted stock unit activity for the three months ended March 31, 2019 is as follows:

| Shares | Weighted Average Grant Date Fair Value
Unvested restricted stock units at January 1, 2019 | 1,110,277 |  | $ | 1.21 |
Granted | 165,000 |  | 1.49 |
Forfeited | — |  | — |
Vested | (17,777 | ) | 1.27 |
Unvested restricted stock units at March 31, 2019 | 1,257,500 |  | $ | — |

12

The fair value of restricted stock that vested during the three month period ending March 31, 2019 was $22.
Deferred Directors Fees
In addition to the Incentive Plans, Fuel Tech has a Deferred Compensation Plans for Directors (Deferred Plan). Under the terms of the Deferred Plan, Directors can elect to defer Directors’ fees for shares of Fuel Tech Common Stock that are issuable at a future date as defined in the agreement. In accordance with ASC 718, Fuel Tech accounts for these awards as equity awards as opposed to liability awards. In the three-month periods ended March 31, 2019 and 2018, Fuel Tech recorded no stock-based compensation expense under the Deferred Plan.
10. Debt Financing
The Company is obligated under a U.S. Domestic credit facility with (the Facility) with JPMorgan Chase Bank, N.A. (JPM Chase) which provides for maximum revolving credit borrowings of $5,500 and matures on June 28, 2019. Fuel Tech can use this Facility for cash advances and standby letters of credit. The Facility is secured by $5,500 in cash held by the Company in a separate restricted use designated JPM Chase deposit account and has the Company’s Italian subsidiary, Fuel Tech S.r.l., as a guarantor. Outstanding borrowings under the Facility bear interest at a rate of LIBOR plus 300 basis points. There are no financial covenants set forth in this amendment to the Facility. The Company is actively pursuing the renewal of its U.S. Domestic credit facility and intends to renew the U.S. Domestic credit facility at its maturity. As of March 31, 2019 and December 31, 2018, there were no outstanding borrowings on the credit facility.
At March 31, 2019 and December 31, 2018, the Company had outstanding standby letters of credit and bank guarantees totaling approximately $5,255 and $5,028, respectively, under the Facility in connection with contracts in process. Fuel Tech is committed to reimbursing the issuing bank for any payments made by the bank under these instruments. The Company pays a commitment fee of 0.25% per year on the unused portion of the revolving credit facility. At March 31, 2019 and December 31, 2018, approximately $245 and $443 was available for future borrowings under the Facility.
Beijing Fuel Tech Environmental Technologies Company, Ltd. (Beijing Fuel Tech), is obligated under a revolving credit facility (the China Facility) agreement with JPM Chase which provides for maximum revolving credit borrowings of RMB 2.625 million (approximately $391) and matures on June 30, 2019. The Facility is secured by $520 in cash held by the Company in a separate restricted use designated JPM Chase deposit account. The China Facility bears interest at a rate of 140% of the People’s Bank of China (PBOC) Base Rate, and is guaranteed by the Company. Beijing Fuel Tech can use this facility for cash advances and bank guarantees. As of March 31, 2019 and December 31, 2018, Beijing Fuel Tech had no cash borrowings under the China Facility. At March 31, 2019 and December 31, 2018, we had no outstanding standby letters of credit and bank guarantees on its Beijing Fuel Tech revolving credit facility in connection with contracts in process. At March 31, 2019 and December 31, 2018, approximately $391 and $382 was available for future borrowings. As a result of the announcement of the suspension of the Air Pollution Control business in Beijing, the Company intends to not renew the China Facility upon its expiration on June 30, 2019.
In the event of default on either the domestic facility or the China facility, the cross default feature in each allows the lending bank to accelerate the payments of any amounts outstanding and may, under certain circumstances, allow the bank to cancel the facility. If the Company were unable to obtain a waiver for a breach of covenant and the bank accelerated the payment of any outstanding amounts, such acceleration may cause the Company’s cash position to deteriorate or, if cash on hand were insufficient to satisfy the payment due, may require the Company to obtain alternate financing to satisfy the accelerated payment.
11. Business Segment and Geographic Financial Data
Business Segment Financial Data
We segregate our financial results into two reportable segments representing two broad technology segments as follows:

• | The Air Pollution Control technology segment includes technologies to reduce NO x emissions in flue gas from boilers, incinerators, furnaces and other stationary combustion sources. These include Low and Ultra Low NO x Burners (LNB and ULNB), Over-Fire Air (OFA) systems, NO x OUT® and HERT™ Selective Non-Catalytic Reduction (SNCR) systems, and Advanced Selective Catalytic Reduction (ASCR™) systems. Our ASCR systems include ULNB, OFA, and SNCR components, along with a downsized SCR catalyst, Ammonia Injection Grid (AIG), and Graduated Straightening Grid GSG™ systems to provide high NO x reductions at significantly lower capital and operating costs than conventional SCR systems. The NO x OUT CASCADE® and NO x OUT-SCR® processes are more basic, using just SNCR and SCR catalyst components. ULTRA™ technology creates ammonia at a plant site using safe urea for use with any SCR application. Flue Gas Conditioning systems are chemical injection systems offered in markets outside the U.S. and Canada to enhance electrostatic precipitator and fabric filter performance in controlling particulate emissions.

13

• | The FUEL CHEM® technology segment, which uses chemical processes in combination with advanced CFD and CKM boiler modeling, for the control of slagging, fouling, corrosion, opacity and other sulfur trioxide-related issues in furnaces and boilers through the addition of chemicals into the furnace using TIFI® Targeted In-Furnace Injection™ technology.

The “Other” classification includes those profit and loss items not allocated to either reportable segment. There are no inter-segment sales that require elimination.
We evaluate performance and allocate resources based on reviewing gross margin by reportable segment. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies (Note 1 in our annual report on Form 10-K). We do not review assets by reportable segment, but rather, in aggregate for the Company as a whole.

12. Leases
Adoption of ASC 842, "Leases"
On January 1, 2019, we adopted ASC 842 using the modified retrospective method outlined in ASU 2018-11 "Leases (Topic 842) Targeted Improvements." Results for reporting periods beginning after January 1, 2019 are presented under ASC 842, while prior period amounts are not adjusted and continue to be reported in accordance with our legacy accounting under Accounting Standards Codification Topic 840: Leases (ASC 840). The Company recorded the transition to ASC 842 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than in the earliest period presented.
We have elected the package of practical expedients permitted under the transition guidance, which among other things, allow us to carry forward the historical accounting relating to lease identification and classification for existing leases upon adoption. We have also elected the practical expedient to not separate lease and non-lease components for the majority of our leases and the election to keep leases with an initial term of 12 months or less off of the consolidated balance sheet.
The cumulative effect of the changes made to our January 1, 2019 consolidated balance sheet for the adoption of ASC 842 were as follows:

| Balance at December 31, 2018 | Adjustments Upon Adoption of ASC 842 | Balance at January 1, 2019
Assets |  |  |
Right-of-use operating lease assets | $ | — |  | $ | 1,592 |  | $ | 1,592 |
Liabilities |  |  |
Other accrued liabilities | 6,099 |  | (22 | ) | 6,077 |
Operating lease liabilities - current | — |  | 650 |  | 650 |
Operating lease liabilities - non-current | — |  | 942 |  | 942 |
Equity |  |  |
Accumulated deficit | (102,495 | ) | 22 |  | (102,473 | )

The adjustment made to the January 1, 2019 consolidated balance sheet related to an accrued liability for lease escalation clauses in certain of our leases under ASC 840 which is a cumulative-effect adjustment to the opening balance of accumulated deficit upon the adoption of ASC 842.
Leases
We have operating leases for eight leased office space locations and certain office equipment. Our leases have remaining lease terms of 1 year to 6 years. Our leases do not contain any material residual value guarantees or material restricted covenants and we currently have no material sublease arrangements. We have no financing leases as defined under ASC 842.
Total operating lease expense for the three-months ended March 31, 2019 is as follows:

| For the three months ended March 31, 2019
Operating lease cost | $ | 172 |
Short-term lease cost | 68 |
Total lease cost | $ | 240 |

The weighted average remaining lease term was 4.25 years as of March 31, 2019. The weighted average discount rate was 3.73% as of March 31, 2019.
15

Remaining maturities of our existing lease liabilities as of March 31, 2019 were as follows:

Year Ending December 31, | Operating Leases
2019 (excluding the three months ended March 31, 2019) | $ | 491 |
2020 | 306 |
2021 | 214 |
2022 | 157 |
2023 | 148 |
Thereafter | 197 |
Total lease payments | $ | 1,513 |
Less imputed interest | (110 | )
Total | $ | 1,403 |

The following is the balance sheet classification of our existing lease liabilities as of March 31, 2019:

Operating lease liabilities - current | $ | 558 |
Operating lease liabilities - non-current | 845 |
Total operating lease liabilities | $ | 1,403 |

Supplemental cash flow information related to leases was as follows:

| For the three months ended March 31, 2019
Cash paid for amounts included in the measurement of lease liabilities | $ | 171 |
Leased assets obtained in exchange for new operating lease liabilities | 163 |

13. Accrued Liabilities
The components of other accrued liabilities are as follows:

| As of
| March 31, 2019 |  | December 31, 2018
Contract liabilities (Note 3) | $ | 902 |  |  | $ | 1,234 |
Accrued remediation contingency (Note 14) | 1,223 |  |  | — |
Other accrued liabilities | 2,775 |  |  | 4,865 |
Total other accrued liabilities | $ | 4,900 |  |  | $ | 6,099 |

14. Contingencies
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 no amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is not probable or the amount is not estimable, or both, if there is a reasonable possibility that a material loss may have been incurred.
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 not materially affect our consolidated financial position, results of operations, or cash flows. We do not 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.
16

During the fourth quarter of 2018, the Company was notified of certain non-conformance issues with a U.S. customer associated with equipment that requires remedy under the warranty provision of the contract. Thus far, the Company is working to resolve this matter including addressing the non-conformance issues without resorting to litigation. During the first quarter of 2019, the Company filed the claim with our insurance carrier and recorded $973 as expected insurance proceeds from our insurance carrier and $1,223 (including the insurance policy deductible of $250) as an accrued liability associated with the completion of the non-conformance issues identified with our customer for the three months ended March 31, 2019. The Company currently has $500 of accounts receivable which is past due associated with this project. Upon satisfactory completion of non-conformance issues identified with the customer, the Company expects to collect the remaining accounts receivable due from the customer.
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.
There was no change in the warranty liability balance during the three-months ended March 31, 2019 and 2018. The warranty liability balance was $159 at March 31, 2019 and 2018.
15. Income Taxes
The Company’s effective tax rate is 0% for the three-month periods ended March 31, 2019 and 2018, respectively. The Company's effective tax rate differs from the statutory federal tax rate of 21% for the three-month periods ended March 31, 2019 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 for the three- month periods ended March 31, 2019 and 2018.
On April 3, 2019, the Company received notice from the Internal Revenue Service that our U.S. income tax return for the year ended December 31, 2016 is currently under audit.
Fuel Tech had no unrecognized tax benefits as of March 31, 2019 and December 31, 2018.
16. Goodwill and Other Intangibles
Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. Fuel Tech has two reporting units for goodwill evaluation purposes: the FUEL CHEM® technology segment and the APC technology segment. There is no goodwill associated with our APC segment. At both March 31, 2019 and December 31, 2018, our entire goodwill balance of $2,116 was allocated to the FUEL CHEM® technology segment.
Goodwill is allocated to each of our reporting units after considering the nature of the net assets giving rise to the goodwill and how each reporting unit would enjoy the benefits and synergies of the net assets acquired. There were no indications of goodwill impairment in the three months ended March 31, 2019 and 2018.
Fuel Tech reviews other intangible assets, which include customer lists and relationships, covenants not to compete, patent assets, tradenames, and acquired technologies, for impairment on a recurring basis or when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event that impairment indicators exist, a further analysis is performed and if the sum of the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded. Management considers historical experience and all available information at the time the estimates of future cash flows are made, however, the actual cash values that could be realized may differ from those that are estimated.
There were no indications of intangible asset impairments for the three month period ended March 31, 2019.
FUEL TECH, INC.
Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Results of Operations
Revenues for the three month periods ending March 31, 2019 and 2018 were $10,155 and $12,791, respectively, representing a decrease of $2,636 or 21% versus the same period last year.
17

The Air Pollution Control (APC) technology segment generated revenues of $5,789 for the three month period ending March 31, 2019, representing a decrease of $2,794 or 33% from the prior year amount of $8,583, respectively. The decrease in APC revenue was principally related to timing of project execution and the decline in backlog of $12.4 million at December 31, 2018 versus $22.1 million at December 31, 2017, resulting from lower new APC orders announced during 2018.
Consolidated APC backlog at March 31, 2019 was $12,219 versus backlog at December 31, 2018 of $12,384. Our current backlog consists of U.S. domestic projects totaling $9,954 and international projects totaling $2,265.
The FUEL CHEM® technology segment generated revenues of $4,366 for the three months ended March 31, 2019, representing an increase of $158 or 4% from the the prior year amount of $4,208. We remain focused on attracting new customers in our FUEL CHEM business, for both coal and noncoal applications, but our ability to attract new coal customers continues to be affected by the soft electric demand market and fuel switching as a result of low natural gas price.
Consolidated gross margin percentage for the three month periods ended March 31, 2019 and 2018 was 40% and 39%. The gross margin percentage for the APC technology segment for the three month periods ended March 31, 2019 and 2018 was 33% and 35%, respectively. The decrease in gross margin is primarily due to project mix and timing of project execution as well as a $250 charge related to remediation efforts for certain non-conformance issues with a U.S customer. For further information, refer to Note 14 - Contingencies.
For the FUEL CHEM technology segment, the gross margin percentage remained consistent at 48% for the three month periods ending March 31, 2019 and 2018.
Selling, general and administrative expenses (SG&A) were $4,458 and $4,921 for the three month periods ended March 31, 2019 and 2018, respectively. For the three month period ended March 31, 2019, this represents a decrease of $463. The decrease was primarily the result of a reduction in administrative costs relating to foreign subsidiaries of $522, largely driven by the suspension of the APC business operation in China. SG&A as a percentage of revenues increased to 44% from 38% in the three month periods ending March 31, 2019 and 2018. The increase in SG&A percentage is primarily attributed to the decrease in revenues due to the timing of project execution as well as lower new APC orders announced during 2018.
During the second quarter of 2017, the Company suspended all operations associated with the Fuel Conversion business segment. The activity of the Fuel Conversion discontinued operations consisted primarily of storage costs for the certain equipment held in Assets held for sale for the three month periods ended March 31, 2019 and 2018 of $10 and $25, respectively. The Fuel Conversion business segment had no revenues associated with it. The overall decline in the discontinued operations for the three month period ending March 31, 2019 in comparison to the same period in 2018 is due to the overall wind-down of operations for the Fuel Conversion discontinued operations.
On January 18, 2019, the Company announced a planned suspension of its APC business operation in China. This action is part of Fuel Tech’s ongoing operational improvement initiatives designed to prioritize resource allocation, reduce costs, and drive profitability for the Company on a global basis. The Company recorded restructuring charges of $595 and $0 for the three months ended March 31, 2019 and 2018, respectively. The charge consisted primarily of one-time severance payments and the early termination penalty for our lease associated with the suspension of our APC business in China. For further information related to restructuring, refer to Note 5 - Restructuring Activities.
Research and development expenses for the three month periods ended March 31, 2019 and 2018 was $266 and $288, respectively. The expenditures in our research and development expenses were focused on new product development efforts in the pursuit of commercial applications for technologies outside of our traditional markets, and in the development and analysis of new technologies that could represent incremental market opportunities. This includes water treatment technologies that include DGI™ Dissolved Gas Infusion Systems, an innovative alternative to current aeration technology. This technology has not yet met the criteria to be a separate operating segment under ASC 280 Segment Reporting. This infusion process has a variety of applications in the water and waste water industries, including remediation, treatment, biological activity and wastewater odor management. DGI technology benefits include reduced energy consumption, installation costs, and operating costs, while improving treatment performance.
Income tax (benefit) expense for the three month periods ended March 31, 2019 and 2018 were $0 and $(1), respectively. The Company is projecting a consolidated effective tax rate of 0% for 2019 which was 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 three months ended March 31, 2019 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
18

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.
On January 1, 2019, we adopted ASC 842 using the modified retrospective method outlined in ASU 2018-11 "Leases (Topic 842) Targeted Improvements." Results for reporting periods beginning after January 1, 2019 are presented under ASC 842, while prior period amounts are not adjusted and continue to be reported in accordance with our legacy accounting under Accounting Standards Codification Topic 840: Leases (ASC 840). The Company recorded the transition to ASC 842 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than in the earliest period presented.
We have elected the package of practical expedients permitted under the transition guidance, which among other things, allow us to carry forward the historical accounting relating to lease identification and classification for existing leases upon adoption. We have also elected the practical expedient to not separate lease and non-lease components for the majority of our leases and the election to keep leases with an initial term of 12 months or less off of the consolidated balance sheet. Refer to Footnote 12 to the Consolidated Financial Statements for the impact of the adoption of ASC 842.
Liquidity and Sources of Capital
At March 31, 2019, Fuel Tech had unrestricted cash and cash equivalents and short-term investments on hand of $7,135 (excluding restricted cash of $6,020) and working capital of $22,021 versus $12,039 (excluding restricted cash of $6,020) and $23,556 at December 31, 2018, respectively.
Operating activities used cash of $4,900 during the three month period ended March 31, 2019. This decrease in cash from operations was due to our net loss of $1,289, a decrease in our accrued liabilities and other non-current liabilities of $1,870, a decrease in accounts payable of $3,174, offset by cash provided by a decrease in accounts receivable of $720, prepaid and other assets of $187 and the effect of non-cash charges of $526.
Investing activities used cash of $224 during the three month period ended March 31, 2019 and primarily related to net cash used for purchases of equipment and patents.
Financing activities used cash of $2 during the three month period ended March 31, 2019 all of which related to cash used for the acquisition of common shares held in treasury that were withheld for taxes due by employees upon vesting of restricted stock units.
The Company is obligated under a U.S. Domestic credit facility with (the Facility) with JPMorgan Chase Bank, N.A. (JPM Chase) which provides for maximum revolving credit borrowings of $5,500 and matures on June 28, 2019. Fuel Tech can use this Facility for cash advances and standby letters of credit. The Facility is secured by $5,500 in cash held by the Company in a separate restricted use designated JPM Chase deposit account and has the Company’s Italian subsidiary, Fuel Tech S.r.l., as a guarantor. Outstanding borrowings under the Facility bear interest at a rate of LIBOR plus 300 basis points. There are no financial covenants set forth in this amendment to the Facility. The Company is actively pursuing the renewal of its U.S. Domestic credit facility and intends to renew the U.S. Domestic credit facility at its maturity. As of March 31, 2019 and December 31, 2018, there were no outstanding borrowings on the credit facility.
At March 31, 2019 and December 31, 2018, the Company had outstanding standby letters of credit and bank guarantees totaling approximately $5,255 and $5,028, respectively, under the Facility in connection with contracts in process. Fuel Tech is committed to reimbursing the issuing bank for any payments made by the bank under these instruments. The Company pays a commitment fee of 0.25% per year on the unused portion of the revolving credit facility. At March 31, 2019 and December 31, 2018, approximately $245 and $443 was available for future borrowings under the Facility.
Beijing Fuel Tech Environmental Technologies Company, Ltd. (Beijing Fuel Tech), is obligated under a revolving credit facility (the China Facility) agreement with JPM Chase which provides for maximum revolving credit borrowings of RMB 2.625 million (approximately $391) and matures on June 30, 2019. The Facility is secured by $520 in cash held by the Company in a separate restricted use designated JPM Chase deposit account. The China Facility bears interest at a rate of 140% of the People’s Bank of China (PBOC) Base Rate, and is guaranteed by the Company. Beijing Fuel Tech can use this facility for cash advances and bank guarantees. As of March 31, 2019 and December 31, 2018, Beijing Fuel Tech had no cash borrowings under the China Facility. At March 31, 2019 and December 31, 2018, we had no outstanding standby letters of credit and bank guarantees on its Beijing Fuel Tech revolving credit facility in connection with contracts in process. At March 31, 2019 and December 31, 2018, approximately $391 and $382 was available for future borrowings. As a result of the announcement of the suspension of the Air Pollution Control business in Beijing, the Company intends to not renew the China Facility upon its expiration on June 30, 2019.
19

In the event of default on either the domestic facility or the China facility, the cross default feature in each allows the lending bank to accelerate the payments of any amounts outstanding and may, under certain circumstances, allow the bank to cancel the facility. If the Company were unable to obtain a waiver for a breach of covenant and the bank accelerated the payment of any outstanding amounts, such acceleration may cause the Company’s cash position to deteriorate or, if cash on hand were insufficient to satisfy the payment due, may require the Company to obtain alternate financing to satisfy the accelerated payment.
We continue to monitor our liquidity needs and in response to our continued 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 sustained losses from continuing operations during the three month period ended March 31, 2019 totaling $1,289. Our cash used from continuing operations for this same period totaled $4,890. We have taken measures to reduce our expense infrastructure and our ability to operate our base businesses prospectively is based on our ability to secure new orders in the APC business and our ability to successfully execute existing APC projects in line with our internal budgets.
Our cash balance as of March 31, 2019 totaled $13,155 (including restricted cash of $6,020), and our working capital totaled $22,021. We do not have any outstanding debt obligations other than our letters of credit, and our current credit agreement does not have any financial covenants as we have moved to a cash collateralized line of credit with our lender.
We have evaluated our ongoing business needs, and considered the cash requirements of our base business of Air Pollution Control and Fuel Chem, as well as our efforts to wind-up our Fuel Conversion business and 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 up our Fuel Conversion business and APC operations in China as well as other research and development initiatives.
Based on this analysis, management believes that currently we have sufficient cash and working capital to operate our base APC and Fuel Chem businesses.
Contingencies and Contractual Obligations
Fuel Tech issues a standard product warranty with the sale of its products to customers as discussed in Note 14. There was no change in the warranty liability balance during the three months ended March 31, 2019.
Forward-Looking Statements
This Quarterly Report on Form 10-Q contains “forward-looking statements,” as defined in Section 21E of the Securities Exchange Act of 1934, as amended, which are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and reflect Fuel Tech’s current expectations regarding future growth, results of operations, cash flows, performance and business prospects, and opportunities, as well as assumptions made by, and information currently available to, our management. Fuel Tech has tried to identify forward-looking statements by using words such as “anticipate,” “believe,” “plan,” “expect,” “estimate,” “intend,” “will,” and similar expressions, but these words are not the exclusive means of identifying forward-looking statements. These statements are based on information currently available to Fuel Tech and are subject to various risks, uncertainties, and other factors, including, but not limited to, those discussed in Fuel Tech’s Annual Report on Form 10-K for the year ended December 31, 2018 in Item 1A under the caption “Risk Factors,” which could cause Fuel Tech’s actual growth, results of operations, financial condition, cash flows, performance and business prospects and opportunities to differ materially from those expressed in, or implied by, these statements. Fuel Tech undertakes no obligation to update such factors or to publicly announce the results of any of the forward-looking statements contained herein to reflect future events, developments, or changed circumstances or for any other reason. Investors are cautioned that all forward-looking statements involve risks and uncertainties, including those detailed in Fuel Tech’s filings with the Securities and Exchange Commission.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
Foreign Currency Risk Management
Fuel Tech’s earnings and cash flow are subject to fluctuations due to changes in foreign currency exchange rates. We do not enter into foreign currency forward contracts nor into foreign currency option contracts to manage this risk due to the immaterial nature of the transactions involved.
Fuel Tech is also exposed to changes in interest rates primarily due to its debt facilities (refer to Note 10 to the consolidated financial statements). A hypothetical 100 basis point adverse move in interest rates along the entire interest rate yield curve would not have a materially adverse effect on interest expense during the upcoming year ended December 31, 2019.
20

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Fuel Tech maintains disclosure controls and procedures and internal controls designed to ensure (a) that information required to be disclosed in Fuel Tech’s filings under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and (b) that such information is accumulated and communicated to management, including the principal executive and financial officer, as appropriate to allow timely decisions regarding required disclosure. Fuel Tech’s Chief Executive Officer and principal financial officer have evaluated the Company’s disclosure controls and procedures, as defined in Rules 13a – 15(e) and 15d -15(e) of the Exchange Act, as of the end of the period covered by this report, and they have concluded that these controls and procedures are effective.
Changes in Internal Control over Financial Reporting
Beginning January 1, 2019, we adopted ASC 842 "Leases". It did not have a material impact on our ongoing net income; however, we implemented changes to our processes related to accounting for leases and related internal controls. These changes included the development of new policies related to the new leasing framework, training, ongoing contract review requirements, and gathering of information to comply with disclosure requirements.
There has been no change in the Company's internal control over financial reporting during the quarter covered by this report that has materially affected, or is reasonably likely to materially affect, its internal control over financial reporting.
