FUEL TECH, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
June 30, 2020
(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 NOx reduction technologies as well as our FUEL CHEM program. The Company’s NOx 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 and six months ended June 30, 2020 are not necessarily indicative of the results to be expected for the full year ending December 31, 2020. 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, 2019 as filed with the Securities and Exchange Commission.
COVID-19 Pandemic
The emergence of the coronavirus (COVID-19) around the world presents significant risks to the Company, not all of which the Company is able to fully evaluate or even foresee at the current time. While the COVID-19 pandemic did not materially adversely affect the Company’s financial results and business operations in the Company’s first fiscal quarter ended March 31, 2020, economic and health conditions in the United States and across most of the globe have changed rapidly. The COVID-19 pandemic has affected the Company’s operations in the three and six months ended June 30, 2020, although the impact of the pandemic is difficult to quantify, and may continue to do so indefinitely thereafter. The Company has experienced, and may continue to experience, reductions in demand for certain of our products as several accounts remained offline due to soft electric demand and unplanned outage activities and 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.

2. Summary of Significant Accounting Policies
Restricted cash
Restricted cash as of June 30, 2020 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 $3,003 is comprised of $2,639 in current assets relating to existing standby letters of credit with varying maturity dates and expire no later than June 30, 2021 and $364 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 9 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 Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statements of Cash Flows:
| June 30, 2020 | June 30, 2019 |
| Cash and cash equivalents | $ | 8,254 | $ | 11,664 |
| Restricted cash included in current assets | 2,639 | 2,768 |
| Restricted cash included in long-term assets | 364 | 487 |
| Total cash, cash equivalents, and restricted cash shown in the Consolidated Statements of Cash Flows | $ | 11,257 | $ | 14,919 |

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 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 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 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.
7
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.
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 1,100 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.
Disaggregated Revenue by Product Technology

Timing of Revenue Recognition
The following table presents the timing of our revenue recognition:
| Three Months Ended June 30, | Six Months Ended June 30, |
| 2020 | 2019 | 2020 | 2019 |
| Products transferred at a point in time | $ | 2,932 | $ | 5,153 | $ | 5,981 | $ | 10,567 |
| Products and services transferred over time | 1,469 | 3,795 | 2,198 | 8,536 |
| Total Revenues | $ | 4,401 | $ | 8,948 | $ | 8,179 | $ | 19,103 |

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 June 30, 2020 and December 31, 2019, contract assets were approximately $1,763 and $1,857, 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 $1,168 and $712, at June 30, 2020 and December 31, 2019, 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, 2020, 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 $210 and $458 for the three and six months ended June 30, 2020, respectively and $707 and $926 for three and six months ended June 30, 2019, respectively, which represented primarily revenue from progress towards completion of our Air Pollution Control technology contracts.
As of June 30, 2020, we had three construction contracts in progress that were identified as loss contracts and a provision for losses of $16 was recorded in other accrued liabilities on the consolidated balance sheet. Refer to Footnote 13 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, 2019, we had three construction contracts in progress that were identified as loss contracts and a provision for losses in the amount of $26 was recorded in other accrued liabilities on the consolidated balance sheet.
9
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, 2020, the aggregate amount of the transaction price allocated to remaining performance obligations was $8,321. The Company expects to recognize revenue on approximately $4,845 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 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 which has taken place through June 30, 2020 includes staff rationalization and reduction, supplier and partner engagement, and the monetization of certain assets. The remaining transition activities include the execution of the remaining activities to satisfy the requirements for the remaining APC projects in China (with a backlog totaling approximately $29) in addition to collection efforts for the remaining accounts receivable.
The following table presents our revenues and net loss (which includes the Restructuring charge line item within the Condensed Statements of Operations for 2020 and 2019 in China as follows:
| Three Months Ended June 30, | Six Months Ended June 30, |
| 2020 | 2019 | 2020 | 2019 |
| Total revenues | $ | 3 | $ | (28 | ) | $ | 5 | $ | 310 |
| Net income (loss) | (85 | ) | (540 | ) | 42 | (1,390 | ) |

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.
The following table presents net assets in China as follows:
| As of |
| June 30, 2020 | December 31, 2019 |
| Total assets | $ | 3,072 | $ | 4,249 |
| Total liabilities | 352 | 399 |
| Total net assets | $ | 2,720 | $ | 3,850 |

The Company incurred $0 in the three and six month periods ending June 30, 2020 and $30 and $625 during the three and six month periods ending June 30, 2019 for severance and lease cancellation costs related to the suspension of the APC business in China.

There is no liability for restructuring activities for the three and six months ending June 30, 2020. 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 and six months ending June 30, 2020 and 2019:
| Three Months Ended June 30, | Six Months Ended June 30, |
| 2020 | 2019 | 2020 | 2019 |

| Amounts paid | — | (248 | ) | — | (535 | ) |
| Restructuring liability at end of period | $ | — | $ | 155 | $ | — | $ | 155 |

5. Accumulated Other Comprehensive Loss
The changes in accumulated other comprehensive loss by component were as follows:
| Three months ended June 30, | Six Months Ended June 30, |
| 2020 | 2019 | 2020 | 2019 |
| Foreign currency translation |
| Balance at beginning of period | $ | (2,009 | ) | $ | (1,181 | ) | $ | (1,778 | ) | $ | (1,285 | ) |
| Other comprehensive loss: |

| Total accumulated other comprehensive loss | $ | (1,857 | ) | $ | (1,224 | ) | $ | (1,857 | ) | $ | (1,224 | ) |

| (1) | In all periods presented, there were no tax impacts related to rate changes and no amounts were reclassified to earnings. |

6. Treasury Stock
Common stock held in treasury totaled 808,139 and 796,090 with a cost of $1,618 and $1,612 at June 30, 2020 and December 31, 2019, 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.
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, 2020 and 2019, 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, 2020 and 2019.
| Three Months Ended June 30, | Six Months Ended June 30, |
| 2020 | 2019 | 2020 | 2019 |
| Basic weighted-average shares | 24,668,000 | 24,187,000 | 24,633,000 | 24,182,000 |
| Conversion of unsecured loan notes | — | — | — | — |
| Unexercised options and unvested RSUs | — | — | — | — |
| Diluted weighted-average shares | 24,668,000 | 24,187,000 | 24,633,000 | 24,182,000 |

Fuel Tech had 553,000 and 1,515,000 weighted average equity awards outstanding at June 30, 2020 and 2019, 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.

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, 2020, Fuel Tech had 2,284,333 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 and six months ended June 30, 2020. 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, 2020. 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 and six months ended June 30, 2020 and 2019 were as follows:
| Three Months Ended June 30, | Six Months Ended June 30, |
| 2020 | 2019 | 2020 | 2019 |
| Stock options and restricted stock units, net of forfeited | $ | 69 | $ | 123 | $ | 150 | $ | 219 |
| Tax benefit of stock-based compensation expense | — | — | — | — |
| After-tax effect of stock-based compensation | $ | 69 | $ | 123 | $ | 150 | $ | 219 |

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, 2020 was as follows:
| NumberofOptions | Weighted-AverageExercise Price | Weighted- AverageRemainingContractualTerm | AggregateIntrinsicValue |
| Outstanding on January 1, 2020 | 747,500 | $ | 3.33 |
| Granted | — | — |
| Exercised | — | — |
| Expired or forfeited | (40,000 | ) | 5.50 |
| Outstanding on June 30, 2020 | 707,500 | $ | 3.21 | 4.48 | $ | — |
| Exercisable on June 30, 2020 | 707,500 | $ | 3.21 | 4.48 | $ | — |

As of June 30, 2020, there was no unrecognized compensation cost related to non-vested stock options granted under the Incentive Plans.
12
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 2020 Executive Performance RSU Award Agreement (the “2020 Agreement”) with certain officers, including its President and Chief Executive Officer pursuant to which each 2020 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 2020 (“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 2020. 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 June 30, 2020, there is $208 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 1.32 years.
A summary of restricted stock unit activity for the six months ended June 30, 2020 is as follows:
| Shares | Weighted AverageGrant DateFair Value |
| Unvested restricted stock units at January 1, 2020 | 775,635 | $ | 1.47 |
| Granted | — | — |
| Forfeited | (25,000 | ) | 0.97 |
| Vested | (120,630 | ) | 1.57 |
| Unvested restricted stock units at June 30, 2020 | 630,005 | $ | 1.47 |

The fair value of restricted stock that vested during the six month period ending June 30, 2020 was $190.
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, 2020 and 2019, Fuel Tech recorded no stock-based compensation expense under the Deferred Plan.
9. Debt Financing
On April 17, 2020, the Company received $1,556 in loan proceeds from the Paycheck Protection Program (the “PPP”), established pursuant to the recently enacted Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and administered by the U.S. Small Business Administration (“SBA”). The unsecured loan is evidenced by a promissory note of the Company dated April 15, 2020 (the “Note”) in the principal amount of $1,556, issued to BMO Harris Bank N.A. (the “Bank”), the lender.
Under the terms of the Note, interest will accrue on the outstanding principal at the rate of 1.0% per annum. The term of the Note is two years, though it may be payable sooner in connection with an event of default under the Note. To the extent the loan amount is not forgiven under the PPP, the Company is obligated to make equal monthly payments of principal and interest, beginning seven months from the date of the Note, until the maturity date. The Note contains covenants by the Company, including obtaining the written consent of the Bank prior to material changes in the management or ownership of the Company.
13
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, 2020 and December 31, 2019, respectively, the Company had outstanding standby letters of credit totaling approximately $2,860 and $2,461 under the BMO Harris agreement. As of June 30, 2020 and December 31, 2019 respectively, the Company held $3,003 and $2,584 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.
In connection with the transition to BMO Harris Bank N.A., the Company canceled its U.S. credit facility with JPMorgan Chase Bank, N.A. effective on September 25, 2019.
10. 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 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.

11. Leases
Leases
We have seven total operating leases which relate to both office space locations and certain office equipment. Our leases have remaining lease terms of 11 months to 5 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 and six months ended June 30, 2020 and 2019 is as follows:
| Three Months Ended June 30, | Six Months Ended June 30, |
| 2020 | 2019 | 2020 | 2019 |

| Other accrued liabilities | 936 | 1,118 |
| Total other accrued liabilities | $ | 2,104 | $ | 1,976 |

13. 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 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. During the second quarter of 2020 a charge of $1,150 to remedy this non-conformance issue was incurred. Offsetting this amount was a reversal of $499 of expense to reduce the allowance of doubtful accounts that had been previously reserved. The Company has completed all work associated with this issue. As of June 30, 2020 and December 31, 2019, we have $0 and $146 of accrued liability associated with the completion of the non-conformance issues in the other accrued liabilities line of the 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 Consolidated Balance Sheets during the six months ended June 30, 2020 and 2019. The warranty liability balance was $159 at June 30, 2020 and 2019.
17
14. Income Taxes
The Company’s effective tax rate is approximately 3% and 0% for the six-month period ended June 30, 2020 and 2019, respectively. The Company's effective tax rate differs from the statutory federal tax rate of 21% for the six month period ended June 30, 2020 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, 2020 and 2019.
Fuel Tech had no unrecognized tax benefits as of June 30, 2020 and December 31, 2019.
On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief, and Economic Security Act (H.R. 748) (the “CARES Act”). Among the changes to the U.S. federal income tax rules, the Cares Act restored net operating loss carryback rules that were eliminated by 2017 Tax Cuts and Jobs Act, restored 100 percent bonus depreciation for qualified improvement property, modified the limit on the deduction for net interest expense and accelerated the timeframe for refunds of AMT credits. At this time we do not anticipate a material impact to the Company’s current or deferred income taxes as a result of the CARES Act. We will continue to evaluate the effects of the CARES Act as additional legislative guidance become available.
15. 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, 2020 and December 31, 2019, 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, 2020 and 2019.
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, 2020 and 2019.
16. 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.

17. 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. 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. In the event we determine we need to raise additional working capital, we may consider various financing alternatives which may include debt financing, common stock offerings, or financing involving convertible debt or other equity-linked securities; however, such financing alternatives may not be available on acceptable terms or at all and any such additional financing could be dilutive to our shareholders.
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, 2020 and 2019 were $4,401 and $8,948, $8,179 and $19,103 respectively, representing a decrease of $4,547 or 51% and $10,924 or 57% versus the same period last year.
The Air Pollution Control (APC) technology segment generated revenues of $1,937 and $3,133 for the three and six month periods ending June 30, 2020, representing a decrease of $2,866 or 60% and $7,459 or 70% from the prior year amount of $4,803 and $10,592. The decrease in APC revenue was principally related to timing of project execution and the decline in backlog of $9.7 million at December 31, 2019 versus $12.4 million at December 31, 2018, resulting from lower new APC orders announced during 2019 and continuing through the first six months of 2020.
Consolidated APC backlog at June 30, 2020 was $8,321 versus backlog at December 31, 2019 of $9,671. Our current backlog consists of U.S. domestic projects totaling $7,193 and international projects totaling $1,128.
The FUEL CHEM® technology segment generated revenues of $2,464 and $5,046 for the three and six months ended June 30, 2020, representing a decrease of $1,681 or 41% and $3,465 or 41% from the prior year amounts of $4,145 and $8,511. The decrease in FUEL CHEM revenue for the three and six months ended June 30, 2020 as compared to the same period of the prior year was due to a reduction in demand from power generation, extended unscheduled outages and significantly reduced operations which were largely impacted by the COVID-19 pandemic. We remain focused on attracting new customers in our FUEL CHEM business, for both coal and non-coal applications, and have recently announced a new order for equipment on three new coal-fired units.
Consolidated gross margin percentage for the three and six month periods ended June 30, 2020 and 2019 were 14% and 26%, and 44% and 41%, respectively. Gross margin for the comparable periods are significantly reduced due to the decline in revenues across the segments and the impact of product mix. The decrease in Fuel Chem margins to 40% from 50% and to 41% from 49% for the three and six month periods ended June 30, 2020 and 2019 was a direct result of the decrease in sales volume as several accounts remained offline due to soft electric demand, extended outages, and to the margin mix of customers generating revenue. The decrease in APC gross margin to (20%) and 2% in the three and six months ending June 30, 2020 from 38% and 35% in 2019 is primarily due to $1,150 of charges incurred to remedy a non-conformance issues with a U.S. customer under a warranty provision of the contract.
Selling, general and administrative expenses (SG&A) were $2,755 and $6,641, and $4,455 and $8,913 respectively for the three and six month periods ended June 30, 2020 and 2019. For the three and six month periods ended June 30, 2020 the decrease of $1,700 and $2,272 is primarily the result of a reduction in administrative costs relating to foreign subsidiaries of $600 and $950 (largely driven by the suspension of the APC business operation in China), a reduction in administrative costs related to employees of $151 and $185, other administrative costs of $294 and $352 and professional and consulting services of $113 and $190. The reversal of a specific reserve of $499 for allowance of doubtful accounts related to the remedy of the aforementioned warranty nonconformity also contributed to this reduction. SG&A as a percentage of revenues increased to 63% and 81% from 50% and 47% in the three and six month periods ending June 30, 2020 and 2019. The increase in SG&A percentage is primarily attributed
19
to the decrease in revenues due to the timing of project execution as well as lower new APC orders announced during 2019 and 2020.
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 $0 and $30, and $0 and $625 for the three and six months ended June 30, 2020 and 2019, respectively. The charge in the six months ended June 30, 2019 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 4 - Restructuring Activities. The Company continues to engage in efforts to complete existing contracts.
Research and development expenses for the three and six-month periods ended June 30, 2020 was $271 and $595, and for the same periods in 2019 was $205 and $471 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 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 expense for the three and six month periods ended June 30, 2020 and 2019 were $31 and $2, and $149 and $2 respectively. The Company is projecting a consolidated effective tax rate of approximately 3% for 2020 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, 2020 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 continuing operations during the six month period ended June 30, 2020 totaling $5,111. Our cash used from continuing operations for this same period totaled $3,414. 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 June 30, 2020 totaled $11,257 (including restricted cash of $3,003), and our working capital totaled $12,133. We have debt obligations of $1,556 from a Paycheck Protection Program (the “PPP”) loan, and we have outstanding letters of credit, under our current credit agreement does which 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, 2020, the Company had outstanding standby letters of credit totaling approximately $2,860 under the BMO Harris
20
agreement. As of June 30, 2020, the Company held $3,003 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.
In connection with the transition to BMO Harris Bank N.A., the Company canceled its U.S. credit facility with JPMorgan Chase Bank, N.A. effective on September 25, 2019.
On April 15, 2020, the Company received $1,556 in loan proceeds from the Paycheck Protection Program (the “PPP”), established pursuant to the recently enacted Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and administered by the U.S. Small Business Administration (“SBA”). The unsecured loan is evidenced by a promissory note of the Company dated April 15, 2020 (the “Note”) in the principal amount of $1,556, issued to BMO Harris Bank N.A. (the “Bank”), the lender.
Under the terms of the Note, interest will accrue on the outstanding principal at the rate of 1.0% per annum. The term of the Note is two years, though it may be payable sooner in connection with an event of default under the Note. To the extent the loan amount is not forgiven under the PPP, the Company is obligated to make equal monthly payments of principal and interest, beginning seven months from the date of the Note, until the maturity date. The Note contains covenants by the Company, including obtaining the written consent of the Bank prior to material changes in the management or ownership of the Company.
The CARES Act and the PPP provide a mechanism for forgiveness of up to the full amount borrowed. Under the PPP, the Company may apply for and be granted forgiveness for all or part of the PPP Loan. The amount of loan proceeds eligible for forgiveness is based on a formula that takes into account a number of factors, including the amount of loan proceeds used by the Company during the eight-week period after the loan origination for certain purposes including payroll costs, rent payments on certain leases, and certain qualified utility payments, provided that at least 75% of the loan amount is used for eligible payroll costs; maintaining or rehiring employees and maintaining salaries at certain levels; and other factors. Subject to the other requirements and limitations on loan forgiveness, only loan proceeds spent on payroll and other eligible costs during the covered eight-week period will qualify for forgiveness. The Company intends to use the entire PPP Loan amount for qualifying expenses, though no assurance is provided that the Company will obtain forgiveness of the PPP Loan in whole or in part.
The Note may be prepaid in part or in full, at any time, without penalty. The Note provides for certain customary events of default, including, but not limited to, failing to make a payment when due under the Note, failure to take actions required by the Note, the Company defaulting under certain agreements in favor of any third party, making false statements, the Company’s insolvency, and the commencement of creditor or forfeiture proceedings against the Company. Upon the occurrence of an event of default, the Bank has customary remedies and may, among other things, require immediate payment of all amounts owed under the Note, collect all amounts owing from the Company, and file suit and obtain judgment against the Company.
Contingencies and Contractual Obligations
Fuel Tech issues a standard product warranty with the sale of its products to customers as discussed in Note 13. There was no change in the warranty liability balance during the six months ended June 30, 2020.
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, 2019 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.
21
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 9 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, 2020.
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.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
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.
Item 1A. Risk Factors
The risk factors included in our Annual Report on Form 10-K for fiscal year ended December 31, 2019 have not materially
changed, except for as follows.
The current COVID-19 pandemic, or the future outbreak of other highly infectious or contagious diseases, could adversely impact or cause disruption to our business, financial condition, results of operations and cash flows.
The continued global spread of the COVID-19 pandemic and the responses thereto are complex and rapidly evolving, and the extent to which the pandemic impacts our business, financial condition and results of operations, including the duration and magnitude of such impacts, will depend on numerous evolving factors that we may not be able to accurately predict or assess, including, but not limited to, the following:
| • | We have experienced, and may continue to experience, reductions in demand for certain of our products and 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. These impacts may continue or worsen if “stay-at-home”, “shelter-in-place”, social distancing, travel restrictions and other similar orders, measures or restrictions remain in place for an extended period of time or are re-imposed after being lifted or eased. |

| • | Illness, travel restrictions or other workforce disruptions could adversely affect our supply chain, our ability to timely and satisfactorily complete our customers’ projects, our ability to provide services to our customers or our other business processes. |

| • | In addition to existing travel restrictions implemented in response to the COVID-19 pandemic, jurisdictions may continue to close borders, impose prolonged quarantines and further restrict travel and business activity, which could materially impair our ability to support our operations and customers (both domestic and international), to source supplies through the global supply chain and to identify, pursue and capture new business opportunities. We also face the possibility of increased overhead or other expenses resulting from compliance with any future government orders or other measures enacted in response to the COVID-19 pandemic. |

COVID-19, and the volatile regional and global economic conditions stemming from the pandemic, as well as reactions to future pandemics or resurgences of COVID-19, could also precipitate or aggravate the other risk factors that we identify in our 2019 Form 10-K, which in turn could materially adversely affect our business, financial condition and results of operations.

Question: What is the increase in the percentage of the total contract assets proportion to the total accounts receivable from December 31, 2019 to June 30, 2020 in percentage?

Solution:
def solution():
     #Define variables name and value
    contract_assets_2020 = 1763
    contract_assets_2019 = 1857
    total_accounts_receivable_2020 = 5658
    total_accounts_receivable_2019 = 6473

    #Do math calculation to get the answer
    contract_assets_percentage_2020 = (contract_assets_2020 / total_accounts_receivable_2020) * 100
    contract_assets_percentage_2019 = (contract_assets_2019 / total_accounts_receivable_2019) * 100
    diff_percentage = contract_assets_percentage_2020 - contract_assets_percentage_2019
    return diff_percentage
