(in thousands, except share and per-share data)
1. General
Organization
Fuel Tech, Inc. and subsidiaries ("Fuel Tech", the "Company", "we", "us" or "our") develops and provides 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.
The Company’s NOx reduction technologies reduce nitrogen oxide emissions from boilers, furnaces and other stationary combustion sources. To reduce NOx emissions, our technologies utilize advanced combustion modification techniques and post-combustion NOx control approaches including non-catalytic, catalytic and combined systems. The Company also 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’s FUEL CHEM® 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™ 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.
Many of Fuel Tech’s products and services rely heavily on the Company’s Computational Fluid Dynamics modeling capabilities, which are enhanced by internally developed, high-end visualization software.
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 and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021. 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, 2020 as filed with the Securities and Exchange Commission.
COVID-19 Pandemic
The effects of the coronavirus (COVID-19) global pandemic has presented 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 due to the delay or abandonment of ongoing or anticipated projects due to our customers’, suppliers’ and other third parties’ financial distress or concern regarding the volatility of global markets.
Management cannot predict the full impact of the COVID-19 pandemic on the Company’s sales and marketing channels and supply chain, and as a result, the ultimate extent of the effects of the COVID-19 pandemic on the Company is highly uncertain and will depend on future developments. Such effects could exist for an extended period of time even after the pandemic might end.
Private Placement Offering
On February 11, 2021, Fuel Tech entered into a securities purchase agreement to issue and sell, in a private placement,

Leases
The Company applies the provisions of Accounting Standards Codification ("ASC") 842, Leases. The Company determines if an arrangement is a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether the Company obtains substantially all of the economic benefits from and has the ability to direct the use of the asset. Right-of-use ("ROU") assets and lease liabilities are recognized at the lease commencement date based on the present value of the future minimum lease payments over the lease term. Operating ROU assets also include the impact of any lease incentives. Operating leases are included in right-of-use ("ROU") operating lease assets, operating lease liabilities - current, and operating lease liabilities - non-current on our Condensed 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, and 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 Condensed Consolidated Balance Sheet.
3. Revenue
The Company recognizes revenue when control of the promised goods or services is transferred to our customers, in an 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 generally 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.
Air Pollution Control Technology
Fuel Tech’s APC contracts are typically to 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.
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’s APC product line also includes ancillary revenue for post contractual goods and services. Revenue associated with these activities are recognized at point in time when delivery of goods or completion of the service obligation is performed.
Fuel Tech has installed over
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.
On occasion, Fuel Tech will engineer and sell its chemical pumping equipment. These projects are similar in nature to the APC projects described above and for those project where control transfers over time, revenue is recognized based on the extent of progress towards completion of the single performance obligation.
For projects containing multiple performance obligations, the Company allocates the transaction price based on the estimated standalone selling price. The Company must develop assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in the contract. The Company utilizes key assumptions to determine the stand-alone selling price, which may include other comparable transactions, pricing considered in negotiating the transaction and the estimated costs. Variable consideration is allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated are consistent with the amounts the Company would expect to receive for the satisfaction of each performance obligation.
The consideration allocated to each performance obligation is recognized as revenue when control is transferred for the related goods or services. For performance obligations which consist of licenses and other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.
The Company receives payments from its customers based on billing schedules established in each contract. Up-front payments and fees are recorded as deferred revenue upon receipt or when due until the Company performs its obligations under these arrangements. Amounts are recorded as accounts receivable when the Company’s right to consideration is unconditional.

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. For the FUEL CHEM technology segment, deliveries made in the current period but billed in subsequent periods are also considered unbilled receivables (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 June 30, 2021 and December 31, 2020, contract assets for APC technology projects were approximately $
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 $
Changes in the contract asset and liability balances during the six month period ended June 30, 2021, were not 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 $

4. Restructuring Activities
On January 18, 2019, the Company announced a planned suspension of its Air Pollution Control (“APC”) business operation in China. This action was 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 which has taken place through June 30, 2021 includes staff rationalization and reduction, supplier and partner engagement, and the monetization of certain assets. The remaining transition activities include the execution of the activities to satisfy the requirements for the remaining APC projects in China (with a backlog totaling approximately $

7. 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 and six months ended June 30, 2021 and June 30, 2020, 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 three and six months ended June 30, 2021 and 2020.

8. 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
We did record any excess tax benefits within income tax expense for the three and six months ended June 30, 2021. Given the Company has a full valuation allowance on its deferred tax assets, there were no excess tax benefits to record for the three and six months ended June 30, 2021. 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 Condensed Consolidated Statements of Operations. The components of stock-based compensation for the three and six months ended June 30, 2021 and 2020 were as follows:

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.

Restricted Stock Units
Restricted stock units (RSUs) granted to employees vest over time based on continued service (typically vesting over a period between and 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 2021 Executive Performance RSU Award Agreement (the “2021 Agreement”) with certain officers, including its President and Chief Executive Officer pursuant to which each 2021 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 2021 (“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 $

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’ 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. During the six month periods ended June 30, 2021 and 2020, Fuel Tech recorded

The Company accounts for the PPP Loan as debt in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 470, Debt and accrues interest in accordance with the interest method under FASB ASC 835-30. When the loan was forgiven, the Company reduced the non-current liability by the amount forgiven and recorded other income in the Condensed Consolidated Statement of Operations.
11. Business Segment and Geographic Financial Data
Business Segment Financial Data
We segregate our financial results into
| • | The Air Pollution Control technology segment includes technologies to reduce NOx emissions in flue gas from boilers, incinerators, furnaces and other stationary combustion sources. These include Low and Ultra Low NOx Burners (LNB and ULNB), Over-Fire Air (OFA) systems, NOxOUT® 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 NOx reductions at significantly lower capital and operating costs than conventional SCR systems. The NOxOUT CASCADE® and NOxOUT-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. |
| • | 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.

14. Commitments and 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.
During the third quarter of 2020, the Company was notified of an equipment component failure at a foreign customer location. The failure is being remedied under the warranty provision of the contract that is in place with the customer and supplier. As of June 30, 2021 and December 31, 2020, respectively, a charge of $
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.

Fuel Tech reviews other intangible assets, which include patent assets, 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.

17. Subsequent Events
The Company has evaluated subsequent events through the filing of this Quarterly Report on Form 10-Q, and determined that there have been no events that have occurred that would require adjustments to our disclosures in the consolidated financial statements.
18 Liquidity
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 experienced continued declines in revenues and recurring losses historically. As a result, we have evaluated our ongoing business needs, and considered the cash requirements of our base business of Air Pollution Control (APC) and Fuel Chem businesses. 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, c) current availability of working capital, and d) support for our research and development initiatives. We continue to monitor our liquidity needs and 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 believe our current cash position and net cash flows expected to be generated from operations are adequate to fund planned operations of the Company for the next 12 months.
FUEL TECH, INC.
Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Results of Operations
Revenues for the three and six month periods ending June 30, 2021 and 2020 were $5,218 and $4,401, $10,251 and $8,179, respectively, representing an increase of $817 or 19% and $2,072 or 25% versus the same period last year.
The Air Pollution Control (APC) technology segment generated revenues of $986 and $1,893 for the three and six month periods ending June 30, 2021, representing a decrease of $951 or 49% and $1,240 or 40% from the prior year amount of $1,937 and $3,133. The decrease in APC revenue was principally related to timing of project execution and the decline in backlog resulting from lower new APC orders announced during 2020 and continuing through the first six months of 2021.
Consolidated APC backlog at June 30, 2021 was $4,943 versus backlog at December 31, 2020 of $5,268. Our current backlog consists of U.S. domestic projects totaling $4,558 and international projects totaling $385.
The FUEL CHEM® technology segment generated revenues of $4,232 and $8,358 for the three and six months ended June 30, 2021, representing an increase of $1,768 or 72% and $3,312 or 66% from the prior year amounts of $2,464 and $5,046. The increase in FUEL CHEM revenue for the three months ended June 30, 2021 as compared to the same period of the prior year was due to revenue from new accounts, increased demand for power generation, and recovery from extended unscheduled outages and significantly reduced operations impacted by the COVID-19 pandemic in 2020.
Consolidated gross margin percentage for the three and six month periods ended June 30, 2021 and 2020 was 50% and 48%, and 14% and 26% respectively. Gross margin increased versus the comparable period due to the concentration of product mix that is heavily FUEL CHEM weighted. FUEL CHEM margins increased to 50% from 40% in the current quarter due to the increase in revenue volume. Gross margins for the three and six months ended June 30, 2021 and 2020 for the APC segment were 49% and 45%, and (20%) and 2% respectively. The increase in APC gross margin in the three and six months ended June 30, 2021 from the same period in 2020 is primarily due to the higher product mix of ancillary products and services and due to the non recurrence of $1,150 of charges incurred to remedy a non-conformance issues with a U.S. customer under a warranty provision of the contract that was recorded in 2020.
Selling, general and administrative expenses (SG&A) were $2,957 and $6,057, and $2,755 and $6,641, respectively for the three and six month periods ended June 30, 2021 and 2020. For the three and six month period ended June 30, 2021 the increase of $202 is primarily the result of an increase in employee related costs of $335 and an increase in certain administrative overhead expenses of $40 offset by a reversal of a $499 charge to the allowance for doubtful accounts recorded in second quarter of 2020. For the six month periods ending June 30, 2021 and 2020, SG&A as a percentage of revenues decreased to 59% from 81%. The decrease versus the comparable period is primarily due to the increase in overall revenues in the current year.
Research and development expenses for the three and six-month periods ended June 30, 2021 were $315 and $730, and for the same periods in 2020 was $271 and $595 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 and more specifically, our DGI™ Dissolved Gas Infusion Systems, an innovative alternative to current aeration technology. 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 expense for the three and six month periods ended June 30, 2021 and 2020 was $10 and $10, and $31 and $149 respectively. The Company is projecting a consolidated effective tax rate of approximately 3% for 2021 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 three and six months ended June 30, 2021 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.
Liquidity and Sources of Capital
We have sustained losses from operations during the six month period ended June 30, 2021 totaling $1,846. Our cash provided by operations for this same period totaled $229.
Our cash balance as of June 30, 2021 totaled $36,562 (including restricted cash of $368), and our working capital totaled $37,892. We have no outstanding debt other than our outstanding letters of credit, under our current credit agreement which does not have any financial covenants as we are currently in a Cash Collateral Security agreement with our lender.
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 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-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. Based on this analysis, management believes that currently we have sufficient cash and working capital to operate our base APC and FUEL CHEM businesses.
On June 19, 2019, the Company entered into a Cash Collateral Security agreement with BMO Harris Bank, N.A. (the BMO Harris agreement) to use for the sole purpose of issuing standby letters of credit. The BMO Harris agreement requires us to pledge as cash collateral 105% of the aggregate face amount of outstanding standby letters of credit. The Company pays 250 basis points on the face values of outstanding letters of credit. There are no financial covenants set forth in the BMO Harris agreement. At June 30, 2021, the Company had outstanding standby letters of credit totaling approximately $351 under the BMO Harris agreement. As of June 30, 2021, the Company held $368 in a separate restricted use designated BMO Harris Bank N.A. deposit account. Fuel Tech is committed to reimbursing the issuing bank for any payments made by the bank under these instruments.
On April 15, 2020, the Company received $1,556 in loan proceeds from the Paycheck Protection Program (the “PPP”), established pursuant to the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and administered by the U.S. Small Business Administration (“SBA”). On January 8, 2021 the Company received full forgiveness from the SBA for the entire balance of loan proceeds used to fund its qualified payroll expenses. When the loan was forgiven, the Company reduced the non-current liability by the amount forgiven and recorded other income in the condensed consolidated statement of operations.
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 six months ended June 30, 2021.
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, 2020 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
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 facility (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, 2021.
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
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.
We are from time to time involved in litigation incidental to our business. We are not currently involved in any litigation in which we believe an adverse outcome would have a material effect on our business, financial conditions, results of operations, or prospects.
The risk factors included in our Annual Report on Form 10-K for fiscal year ended December 31, 2020 have not materially changed.

1. General
Organization
Fuel Tech, Inc. and subsidiaries ("Fuel Tech", the "Company", "we", "us" or "our") develops and provides 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.
The Company’s NOx reduction technologies reduce nitrogen oxide emissions from boilers, furnaces and other stationary combustion sources. To reduce NOx emissions, our technologies utilize advanced combustion modification techniques and post-combustion NOx control approaches including non-catalytic, catalytic and combined systems. The Company also 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’s FUEL CHEM® 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™ 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.
Many of Fuel Tech’s products and services rely heavily on the Company’s Computational Fluid Dynamics modeling capabilities, which are enhanced by internally developed, high-end visualization software.
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 and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021. 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, 2020 as filed with the Securities and Exchange Commission.
COVID-19 Pandemic
The effects of the coronavirus (COVID-19) global pandemic has presented 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 due to the delay or abandonment of ongoing or anticipated projects due to our customers’, suppliers’ and other third parties’ financial distress or concern regarding the volatility of global markets.
Management cannot predict the full impact of the COVID-19 pandemic on the Company’s sales and marketing channels and supply chain, and as a result, the ultimate extent of the effects of the COVID-19 pandemic on the Company is highly uncertain and will depend on future developments. Such effects could exist for an extended period of time even after the pandemic might end.
Private Placement Offering
On February 11, 2021, Fuel Tech entered into a securities purchase agreement to issue and sell, in a private placement, 5,000,000 shares of Common Stock and 2,500,000 warrants exercisable for a total of 2,500,000 shares of Common Stock with an exercise price of $5.10 per Warrant Share, at a purchase price of $5.1625 per Share and associated warrant. The gross proceeds to the Company from the Private Placement were $25,812, before deducting placement agent fees and offering expenses of $1,783. Subject to certain ownership limitations, the Warrants are immediately exercisable upon issuance and expire on the and one-half year anniversary of the effective date of the registration statement registering the Warrant Shares for resale. In addition, the Company issued to the placement agent Warrants to purchase up to 350,000 shares of Common Stock. The Placement Agent Warrants are exercisable at an exercise price of $6.45 per share of Common Stock and expire on the and one-half year anniversary of the effective date of the registration statement registering the Shares and the Warrant Shares for resale.

2. Summary of Significant Accounting Policies
Restricted cash
Restricted cash as of June 30, 2021 represents funds that are restricted to satisfy any amount borrowed against the Company's Cash Collateral Security agreement with BMO Harris Bank N.A. The balance of restricted cash totaling $368 is comprised of $98 in current assets relating to existing standby letters of credit with varying maturity dates and expire no later than June 30, 2022 and $270 in long-term assets will remain through the expiration dates of the underlying standby letter of credits (the latest maturity date is February 1, 2023) with BMO Harris Bank N.A. Refer to Note 10 Debt Financing for further information on the Cash Collateral Security agreement with BMO Harris Bank N.A.
The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Condensed Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Condensed Consolidated Statements of Cash Flows:
Leases
The Company applies the provisions of Accounting Standards Codification ("ASC") 842, Leases. The Company determines if an arrangement is a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether the Company obtains substantially all of the economic benefits from and has the ability to direct the use of the asset. Right-of-use ("ROU") assets and lease liabilities are recognized at the lease commencement date based on the present value of the future minimum lease payments over the lease term. Operating ROU assets also include the impact of any lease incentives. Operating leases are included in right-of-use ("ROU") operating lease assets, operating lease liabilities - current, and operating lease liabilities - non-current on our Condensed 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, and 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 Condensed Consolidated Balance Sheet.

| Revenue from Contract with Customer [Text Block] |
3. Revenue
The Company recognizes revenue when control of the promised goods or services is transferred to our customers, in an 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 generally 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.
Air Pollution Control Technology
Fuel Tech’s APC contracts are typically to 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.
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’s APC product line also includes ancillary revenue for post contractual goods and services. Revenue associated with these activities are recognized at point in time when delivery of goods or completion of the service obligation is performed.
Fuel Tech has installed over 1,200 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.
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.
On occasion, Fuel Tech will engineer and sell its chemical pumping equipment. These projects are similar in nature to the APC projects described above and for those project where control transfers over time, revenue is recognized based on the extent of progress towards completion of the single performance obligation.
For projects containing multiple performance obligations, the Company allocates the transaction price based on the estimated standalone selling price. The Company must develop assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in the contract. The Company utilizes key assumptions to determine the stand-alone selling price, which may include other comparable transactions, pricing considered in negotiating the transaction and the estimated costs. Variable consideration is allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated are consistent with the amounts the Company would expect to receive for the satisfaction of each performance obligation.
The consideration allocated to each performance obligation is recognized as revenue when control is transferred for the related goods or services. For performance obligations which consist of licenses and other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.
The Company receives payments from its customers based on billing schedules established in each contract. Up-front payments and fees are recorded as deferred revenue upon receipt or when due until the Company performs its obligations under these arrangements. Amounts are recorded as accounts receivable when the Company’s right to consideration is unconditional.
Disaggregated Revenue by Product Technology
The following table presents our revenues disaggregated by product technology:
Disaggregated Revenue by Geography
The following table presents our revenues disaggregated by geography, based on the billing addresses of our customers:
Timing of Revenue Recognition
The following table presents the timing of our revenue recognition:
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. For the FUEL CHEM technology segment, deliveries made in the current period but billed in subsequent periods are also considered unbilled receivables (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 June 30, 2021 and December 31, 2020, contract assets for APC technology projects were approximately $406 and $2,080, respectively, and $0 and $269, respectively, for the FUEL CHEM technology segment, and are included in accounts receivable on the condensed 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 $694 and $850, at June 30, 2021 and December 31, 2020, respectively, and are included in other accrued liabilities on the consolidated balance sheets.
Changes in the contract asset and liability balances during the six month period ended June 30, 2021, were not 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 $49 and $157 for the three and six months ended June 30, 2021, and $210 and $458 for three and six months ended June 30, 2020, which represented primarily revenue from progress towards completion of our Air Pollution Control technology contracts.
As of June 30, 2021, we had one construction contract in progress that was identified as a loss contract and a provision for losses of $11 was recorded in other accrued liabilities on the condensed consolidated balance sheet. Refer to Footnote 14 for an accrual related to an equipment failure issue with a Customer that requires remedy under the warranty provision of the customer contract. As of December 31, 2020, we had one construction contract in progress that was identified as a loss contract and a provision for losses in the amount of $176 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 June 30, 2021, the aggregate amount of the transaction price allocated to remaining performance obligations was $4,943. The Company expects to recognize revenue on approximately $2,825 of the remaining performance obligations over the next 12 months with the remaining recognized thereafter.

4. Restructuring Activities
On January 18, 2019, the Company announced a planned suspension of its Air Pollution Control (“APC”) business operation in China. This action was 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 which has taken place through June 30, 2021 includes staff rationalization and reduction, supplier and partner engagement, and the monetization of certain assets. The remaining transition activities include the execution of the activities to satisfy the requirements for the remaining APC projects in China (with a backlog totaling approximately $12) in addition to collection efforts for the remaining accounts receivable.
The following table presents our revenues and net income (loss) which includes the Restructuring charge line item within the Condensed Statements of Operations for 2021 and 2020 in China as follows:
Total assets primarily consist of cash, accounts receivable, contract assets, prepaid expenses and other current assets. Total liabilities consist of accounts payable and certain accrued liabilities.

7. 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 and six months ended June 30, 2021 and June 30, 2020, 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 three and six months ended June 30, 2021 and 2020.
Fuel Tech had 160,000 and 553,000 weighted average equity awards outstanding at June 30, 2021 and 2020, 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.

| Share-based Payment Arrangement [Text Block] |
8. 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 June 30, 2021, Fuel Tech had 2,603,801 shares available for share-based awards under the 2014 Plan.
We did record any excess tax benefits within income tax expense for the three and six months ended June 30, 2021. Given the Company has a full valuation allowance on its deferred tax assets, there were no excess tax benefits to record for the three and six months ended June 30, 2021. 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 Condensed Consolidated Statements of Operations. The components of stock-based compensation for the three and six months ended June 30, 2021 and 2020 were as follows:
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 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 six months ended June 30, 2021 was as follows:
As of June 30, 2021, 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 and 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 2021 Executive Performance RSU Award Agreement (the “2021 Agreement”) with certain officers, including its President and Chief Executive Officer pursuant to which each 2021 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 2021 (“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 $1 million in Operating Income in 2021. If awarded, such RSUs will vest in equal amounts (i.e., and ) 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. Currently there is no expense reflected in the financial statements for these awards as the achievement is not considered probable.
At June 30, 2021, there is $59 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 0.72 years.
A summary of restricted stock unit activity for the six months ended June 30, 2021 is as follows:
The fair value of restricted stock that vested during the six month period ending June 30, 2021 was $75.
Deferred Directors Fees
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’ 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. During the six month periods ended June 30, 2021 and 2020, Fuel Tech recorded no stock-based compensation expense under the Deferred Plan. |

9. Warrants
On February 11, 2021, Fuel Tech entered into a securities purchase agreement to issue and sell, in a private placement, 5,000,000 shares of Common Stock and 2,500,000 warrants exercisable for a total of 2,500,000 shares of Common Stock with an exercise price of $5.10 per Warrant Share, at a purchase price of $5.1625 per Share and associated warrant.

Subject to certain ownership limitations, the Warrants are immediately exercisable upon issuance and expire on the and one-half year anniversary of the effective date of the registration statement registering the Warrant Shares for resale. In addition, the Company issued to the placement agent Warrants to purchase up to 350,000 shares of Common Stock. The Placement Agent Warrants are exercisable at an exercise price of $6.45 per share of Common Stock and expire on the and one-half year anniversary of the effective date of the registration statement registering the Shares and the Warrant Shares for resale.
Fuel Tech uses the Black-Scholes option pricing model to estimate the grant date fair value of the warrants. The principal variable assumptions utilized in valuing warrants and the methodology for estimating such model inputs are: (1) risk-free interest rate of 0.59%, an estimate based on the yield of zero–coupon treasury securities with a maturity equal to the expected life of the warrant; (2) expected volatility of 94.66% – an estimate based on the historical volatility of Fuel Tech’s Common Stock for a period equal to the expected life of the warrant; and (3) expected life of the warrant of and one-half years based on the term of the warrant.
The calculated fair value allocated to the warrants is $7,337. This amount has been recorded as Additional paid in capital - warrants and is shown net in the Additional paid in capital line of the condensed consolidated balance sheets.
The issuance of warrants to purchase shares of the Company's common stock are summarized as follows:

14. Commitments and 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.
During the third quarter of 2020, the Company was notified of an equipment component failure at a foreign customer location. The failure is being remedied under the warranty provision of the contract that is in place with the customer and supplier. As of June 30, 2021 and December 31, 2020, respectively, a charge of $11 and $176 was recorded in the other accrued liabilities line of the condensed consolidated balance sheets.
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 included in the other accrued liabilities line of the Condensed Consolidated Balance Sheets during the six months ended June 30, 2021 and 2020. The warranty liability balance was $159 at June 30, 2021 and December 31, 2020. |

15. Income Taxes
The Company’s effective tax rate is approximately 2.6% and 3% for the six-month periods ended June 30, 2021 and 2020, respectively. The Company's effective tax rate differs from the statutory federal tax rate of 21% for the six month period ended June 30, 2021 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 six month periods ended June 30, 2021 and 2020. Income generated in the six months ended June 30, 2021 attributed to the gain on forgiveness of the Paycheck Protection Plan loan is tax exempt.
Fuel Tech had no unrecognized tax benefits as of June 30, 2021 and December 31, 2020.

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 June 30, 2021 and December 31, 2020, 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 six months ended June 30, 2021 and 2020.
Fuel Tech reviews other intangible assets, which include patent assets, 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 six month periods ended June 30, 2021 and 2020.

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 experienced continued declines in revenues and recurring losses historically. As a result, we have evaluated our ongoing business needs, and considered the cash requirements of our base business of Air Pollution Control (APC) and Fuel Chem businesses. 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, c) current availability of working capital, and d) support for our research and development initiatives. We continue to monitor our liquidity needs and 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 believe our current cash position and net cash flows expected to be generated from operations are adequate to fund planned operations of the Company for the next 12 months.

| Lessee, Leases [Policy Text Block] | Leases
The Company applies the provisions of Accounting Standards Codification ("ASC") 842, Leases. The Company determines if an arrangement is a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether the Company obtains substantially all of the economic benefits from and has the ability to direct the use of the asset. Right-of-use ("ROU") assets and lease liabilities are recognized at the lease commencement date based on the present value of the future minimum lease payments over the lease term. Operating ROU assets also include the impact of any lease incentives. Operating leases are included in right-of-use ("ROU") operating lease assets, operating lease liabilities - current, and operating lease liabilities - non-current on our Condensed 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, and 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 Condensed Consolidated Balance Sheet.
