On January 1, 2019, we adopted ASC 842 using the modified retrospective method outlined in ASU 2018-11, “Leases (Topic 842) Targeted Improvements.” Refer to Note 12 for further details regarding the effect of adoption. We determine if an arrangement is a lease at inception. Operating leases are included in right-of-use ("ROU") operating lease assets, operating lease liabilities - current, and operating lease liabilities - non-current on our Consolidated Balance Sheets.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

We have lease agreements with lease and non-lease components, which we elected the practical expedient to not separate lease and non-lease components for the majority of our leases. For certain equipment leases, such as vehicles, we account for the lease and non-lease components as a single lease component. We also elected the practical expedient to keep leases with an initial term of 12 months or less off of the consolidated balance sheet.

The Company recognizes revenue when control of the promised goods or services is transferred to our customers, in amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Fuel Tech’s sales of products to customers represent single performance obligations. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue.

We generally expense sales commissions on a ratable basis when incurred because the amortization period would have been one year or less. These costs are recorded within selling, general and administrative expenses within the Condensed Consolidated Statements of Operations.

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 has installed over 1,000 units with APC technology and normally provides performance guarantees to our customers based on the operating conditions for the project. As part of the project implementation process, we perform system start-up and optimization services that effectively serve as a test of actual project performance. We believe that this test, combined with the accuracy of the modeling that is performed, enables revenue to be recognized prior to the receipt of formal customer acceptance.

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:

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~~September 30, 2019 and December 31, 2018, contract assets were approximately ~~$2,338~~$1,589 and $5,540, respectively, and are included in accounts receivable on the consolidated balance sheets.

However, the Company will periodically bill in advance of costs incurred before revenue is recognized, resulting in contract liabilities. These liabilities are reported on the consolidated balance sheet on a contract-by-contract basis at the end of each reporting period. Contract liabilities were ~~$1,147~~$682 and $1,234, at ~~June~~September 30, 2019 and December 31, 2018, respectively, and are included in other accrued liabilities on the consolidated balance sheets.

Changes in the contract asset and liability balances during the ~~six~~nine month period ended ~~June~~September 30, 2019, 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 ~~$707~~$302 and ~~$926~~$1,059 for the three and ~~six~~nine months ended ~~June~~September 30, 2019 and ~~$216~~$7 and ~~$2,158~~$2,165 for three and ~~six~~nine months ended ~~June~~September 30, 2018, respectively, which represented primarily revenue from progress towards completion of our Air Pollution Control technology contracts.

As of ~~June~~September 30, 2019, we had six construction contracts in progress that were identified as loss contracts and a provision for losses of ~~$73~~$74 was recorded in other accrued liabilities on the consolidated balance sheet. Refer to Footnote 14 for an accrual related to certain non-conformance issues with a U.S. customer associated with equipment that requires remedy under the warranty provision of the customer contract. As of December 31, 2018, we had five construction contracts in progress that were identified as loss contracts and a provision for losses in the amount of $123 was recorded in other accrued liabilities on the consolidated balance sheet.

Remaining Performance Obligations

Remaining performance obligations, represents the transaction price of Air Pollution Control technology booked orders for which work has not been performed. As of ~~June~~September 30, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was ~~$7,953.~~$6,773. The Company expects to recognize revenue on approximately ~~$6,257~~$5,150 of the remaining performance obligations over the next 12 months with the remaining recognized thereafter.

The components of accounts receivable are as follows:

4. Discontinued Operations

During the second quarter of 2017, the Company suspended all operations associated with the Fuel Conversion business segment. The components of the net assets of the Fuel Conversion discontinued operations are Assets held for sale (which consists primarily of certain equipment) on the Consolidated Balance Sheets totaling ~~$396~~$0 and $485 as of ~~June~~September 30, 2019 and December 31, 2018, respectively. The Company sold ~~certain equipment within Assets held for sale for the six month period ended June 30, 2019 of $55. Additionally, on July 10, 2019 the Company entered into an agreement to sell~~ the remaining Fuel Conversion equipment within Assets held for sale ~~for a purchase price of $500 (less applicable commission of $50 to~~during the ~~third party equipment reseller). The Company incurred storage costs of $13 for holding the equipment at a third-party location for the six~~nine month period ended ~~June~~September 30, ~~2019.~~2019 for sales proceeds net of selling costs of $505, resulting in a gain on sale of $20 recorded in discontinued operations. Following the ~~movement~~sale of the remaining Fuel Conversion equipment ~~by the customer~~ during the third quarter, ~~from our third-party storage facility,~~ the Company ~~will incur no additional costs associated with the completion of~~completed the wind-down activities associated with the Fuel Conversion business segment.

In addition, accrued severance of $5$0 and $65 is included in the other accrued liabilities line of the Consolidated Balance Sheets as of ~~June~~September 30, 2019 and December 31, 2018, respectively. A total of ~~$30~~$5 and ~~$60~~$65 was paid ~~for~~during the three and ~~six~~nine months ended ~~June~~September 30, ~~2019, the remaining $5 will be paid in the third quarter of~~ 2019.

The Fuel Conversion business segment had no other assets or liabilities associated with it.

The activity of the Fuel Conversion discontinued operations consisted primarily of storage costs for holding the ~~certain~~ equipment ~~held in Assets held for sale of $9~~at a third-party location totaling $2 and ~~$19~~$21 for the three and ~~six month periods~~nine months ended ~~June~~September 30, 2019 ~~respectively,~~ and the gain on sale of $20 recorded in discontinued operations during the third quarter. The activity for the ~~same periods in~~Fuel Conversion discontinued operations consisted of Research and Development, severance and other costs for the three and nine months ended September 30, 2018 of ~~$74~~$10 and ~~$99,~~$109, respectively. The Fuel Conversion business segment had no revenues associated with it.

5. Restructuring Activities

On January 18, 2019, the Company announced a planned suspension of its Air Pollution Control (“APC”) business operation in ~~China (“Beijing Fuel Tech”).~~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 ~~is underway, and~~which has taken place through September 30, 2019 includes staff rationalization and reduction, supplier and partner engagement, and the monetization of certain assets. The ~~Company expects~~remaining transition activities include the execution of the remaining activities to ~~complete~~satisfy the ~~process during~~requirements for the ~~second half of 2019.~~remaining APC projects in China (with a backlog totaling approximately $47) 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) in China ~~for the three and six month periods ended June 30, 2019 and 2018:~~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.

The following table presents net assets in China as follows:

As of
June 30, 2019 December 31, 2018
Total assets $ 5,493
$ 8,546
Total liabilities (1,199 ) (2,953 )
Total net assets $ 4,294
$ 5,593

Total assets primarily consist of accounts receivable, contract assets, inventory, prepaid expenses and property, plant and equipment. Total liabilities consist of accounts payable and certain accrued liabilities.



	As of

Total liabilities	(266		)	(2,953		)
Total net assets	$	4,042		$	5,593

The Company ~~has~~ incurred approximately $562 of severance costs relating to the suspension of the APC business in China, of which ~~$278~~$90 and ~~$535~~$562 were paid during the three and ~~six~~nine months ended ~~June~~September 30, 2019. ~~$90 is expected to be paid in the third quarter of 2019.~~

On January 23, 2019, the Company notified the landlord of our intention to early terminate the lease on July 22, 2019. The Company incurred an early termination penalty of $63 during the first quarter of 2019, which is included in restructuring expense for the ~~six~~nine months ended ~~June~~September 30, 2019. ~~The Company will incur no additional costs associated with the completion of the wind-down activities associated with the suspension of the APC business in China.~~

The Company recorded restructuring charges of ~~$30~~$0 and $625 for the three and ~~six~~nine months ended ~~June~~September 30, 2019 and $0 and $0 in 2018, respectively. The charge consisted primarily of one-time severance costs of $562 and the early termination penalty for our lease associated with the suspension of our APC business in China of $63. The following is a reconciliation of the accrual for the workforce reduction that is included within the "Accrued Liabilities - Employee Compensation" line of the consolidated balance sheets for the three and ~~six~~nine months ending ~~June~~September 30, 2019 and 2018:

The restructuring liability for the three and ~~six~~nine months ended ~~June~~September 30, 2018 relates to severance costs associated with the suspension of the Fuel Conversion business segment.

6. Accumulated Other Comprehensive Loss

The changes in accumulated other comprehensive loss by component were as follows:

Common stock held in treasury totaled 656,844 and 655,306 with a cost of $1,486 and $1,484 at ~~June~~September 30, 2019 and December 31, 2018, respectively. These shares were withheld from employees to settle personal tax withholding obligations that arose as a result of restricted stock units that vested in the periods presented.

8. Earnings per Share

Basic earnings per share excludes the dilutive effects of stock options, restricted stock units (RSUs), and the nil coupon non-redeemable convertible unsecured loan notes. Diluted earnings per share includes the dilutive effect of the nil coupon non-redeemable convertible unsecured loan notes, RSUs, and unexercised in-the-money stock options, except in periods of net loss where the effect of these instruments is anti-dilutive. Out-of-money stock options are excluded from diluted earnings per share because they are anti-dilutive. For the three and ~~six~~nine months ended ~~June~~September 30, 2019 and for the nine months ended September 30, 2018, basic earnings per share is equal to diluted earnings per share because all outstanding stock awards and convertible loan notes are considered anti-dilutive during periods of net loss. For the three months ended September 30, 2018, diluted earnings per share includes unexercised options and unvested RSUs since net income was generated in that period and the effect of those instruments is dilutive. The following table sets forth the weighted-average shares used in calculating the earnings per share for the three and ~~six~~nine months ended ~~June~~September 30, 2019 and 2018.

Fuel Tech had ~~1,515,000~~1,269,000 and ~~1,288,000~~1,286,000 weighted average equity awards outstanding at ~~June~~September 30, 2019 and 2018, respectively, that were not dilutive for the purposes of inclusion in the calculation of diluted earnings per share but could potentially become dilutive in future periods.

9. Stock-Based Compensation

Under our stock-based employee compensation plan, referred to as the Fuel Tech, Inc. 2014 Long-Term Incentive Plan (Incentive Plan), awards may be granted to participants in the form of Non-Qualified Stock Options, Incentive Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units (“RSUs”), Performance Awards, Bonuses or other forms of share-based or non-share-based awards or combinations thereof. Participants in the Incentive Plan may be our directors, officers, employees, consultants or advisors (except consultants or advisors in capital-raising transactions) as the directors determine are key to the success of our business. There are a maximum of 5,600,676 shares that may be issued or reserved for awards to participants under the Incentive Plan. As of ~~June~~September 30, 2019, Fuel Tech had 2,092,136 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~~nine months ended ~~June~~September 30, 2019. Given the Company has a full valuation allowance on its deferred tax assets, there were no excess tax benefits to record for the three and ~~six~~nine months ended ~~June~~September 30, 2019. In addition, we account for forfeitures of awards based on an estimate of the number of awards expected to be forfeited and adjusting the estimate when it is no longer probable that the employee will fulfill the service condition.

Stock-based compensation is included in selling, general, and administrative costs in our Consolidated Statements of Operations. The components of stock-based compensation for the three and ~~six~~nine months ended ~~June~~September 30, 2019 and 2018 were as follows:

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~~nine months ended ~~June~~September 30, 2019 was as follows:

As of ~~June~~September 30, 2019, there was no unrecognized compensation cost related to non-vested stock options granted under the Incentive Plans.

Restricted Stock Units

Restricted stock units (RSUs) granted to employees vest over time based on continued service (typically vesting over a period between two and four years). Such time-vested RSUs are valued at the date of grant using the intrinsic value method based on the closing price of the Common Shares on the grant date. Compensation cost, adjusted for estimated forfeitures, is amortized on a straight-line basis over the requisite service period.

In addition to the time vested RSUs, the Company entered into a 2019 Executive Performance RSU Award Agreement (the “2019 Agreement”) with certain officers, including its President and Chief Executive Officer and Principal Financial Officer and Controller pursuant to which each 2019 Participating Executive will have the opportunity to earn a specified amount of restricted stock units (RSUs). The amount of RSUs awarded, if any, will be based on the Company’s achievement of varying levels of operating income before the impact of incentive pay (but including adjustments to reflect the payment of sales commissions) in fiscal 2019 (“Operating Income”), as determined by the Company, in its sole discretion. Nevertheless, no Participating Executive will be entitled to any such RSUs unless the Company achieves a minimum of $2 million in Operating Income in 2019. If awarded, such RSUs will vest in equal amounts (i.e., 1/3, 1/3 and 1/3) over three years commencing one year after the grant date based on continued service. Such RSUs are valued at the date of grant using the intrinsic value method based on the closing price of the Company’s common stock on the grant date.

At ~~June~~September 30, 2019, there is ~~$630~~$489 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 ~~1.66~~1.56 years.

A summary of restricted stock unit activity for the ~~six~~nine months ended ~~June~~September 30, 2019 is as follows:

The fair value of restricted stock that vested during the ~~six~~nine month period ending ~~June~~September 30, 2019 was $22.

Deferred Directors Fees

In addition to the Incentive Plans, Fuel Tech has a Deferred Compensation Plans for Directors (Deferred Plan). Under the terms of the Deferred Plan, Directors can elect to defer Directors’ fees for shares of Fuel Tech Common Stock that are issuable at a future date as defined in the agreement. In accordance with ASC 718, Fuel Tech accounts for these awards as equity awards as opposed to liability awards. During the ~~six-month~~nine month periods ended ~~June~~September 30, 2019 and 2018, Fuel Tech recorded no stock-based compensation expense under the Deferred Plan.

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~~September 30, 2019, the Company had outstanding standby letters of credit totaling approximately ~~$463~~$2,361 under the BMO Harris agreement. As of ~~June~~September 30, 2019, the Company held ~~$502~~$2,482 in a separate restricted use designated BMO Harris Bank N.A. deposit account.

In connection with the transition to BMO Harris Bank N.A., the Company entered into an amendment under its U.S. Domestic credit facility (the Facility) with JPMorgan Chase Bank, N.A. (JPM Chase) to reduce the maximum revolving credit borrowings from $5,500 to $2,750 and extended the maturity to December 31, 2019. Fuel Tech maintains the use of this Facility for its existing standby letters of credit. The Company intends to transition its existing letters of credit from JPM Chase to BMO Harris Bank, N.A. and not renew the Facility upon its maturity. The Facility is secured by $2,750 in cash held by the Company in a separate restricted use designated JPM Chase deposit account and has the Company’s Italian subsidiary, Fuel Tech S.r.l., as a guarantor. Outstanding borrowings under the Facility bear interest at a rate of LIBOR plus 300 basis points. There are no financial covenants set forth in this amendment to the Facility. As of June 30, 2019 and December 31, 2018, there were no outstanding borrowings on the credit facility.

At June 30, 2019 and December 31, 2018, the Company had outstanding standby letters of credit and bank guarantees totaling approximately $2,550 and $5,028, respectively, under the Facility in connection with contracts in process. Fuel Tech is committed to reimbursing the issuing bank for any payments made by the bank under these instruments. ~~At June 30, 2019 and December 31, 2018, approximately $200 and $443 was available for future borrowings under the Facility.~~

In connection with the ~~event of default on the JPM Chase domestic facility, the cross default feature in each allows the lending bank~~transition to ~~accelerate the payments of any amounts outstanding and may, under certain circumstances, allow the bank to cancel the facility. If~~BMO Harris Bank N.A., the Company were unable to obtain a waiver for a breach of covenant and the bank accelerated the payment of any outstanding amounts, such acceleration may cause the Company’s cash position to deteriorate or, if cashcanceled its U.S. Domestic credit facility with JPMorgan Chase Bank, N.A. effective on ~~hand were insufficient to satisfy the payment due, may require the Company to obtain alternate financing to satisfy the accelerated payment.~~September 25, 2019.

11. Business Segment and Geographic Financial Data

Business Segment Financial Data

We segregate our financial results into two reportable segments representing two broad technology segments as follows:

The Air Pollution Control technology segment includes technologies to reduce NO_x emissions in flue gas from boilers, incinerators, furnaces and other stationary combustion sources. These include Low and Ultra Low NO_x Burners (LNB and ULNB), Over-Fire Air (OFA) systems, NO_xOUT^® and HERT™ Selective Non-Catalytic Reduction (SNCR) systems, and Advanced Selective Catalytic Reduction (ASCR^™) systems. Our ASCR systems include ULNB, OFA, and SNCR components, along with a downsized SCR catalyst, Ammonia Injection Grid (AIG), and Graduated Straightening Grid GSG™ systems to provide high NO_x reductions at significantly lower capital and operating costs than conventional SCR systems. The NO_xOUT CASCADE^® and NO_xOUT-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.

Information about reporting segment net sales and gross margin from continuing operations are provided below:

Geographic Segment Financial Data

Information concerning our operations by geographic area is provided below. Revenues are attributed to countries based on the location of the customer. Assets are those directly associated with operations of the geographic area.

12. Leases

Adoption of ASC 842, "Leases"

On January 1, 2019, we adopted ASC 842 using the modified retrospective method outlined in ASU 2018-11 "Leases (Topic 842) Targeted Improvements." Results for reporting periods beginning after January 1, 2019 are presented under ASC 842, while prior period amounts are not adjusted and continue to be reported in accordance with our legacy accounting under Accounting Standards Codification Topic 840: Leases (ASC 840). The Company recorded the transition to ASC 842 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than in the earliest period presented.

We have elected the package of practical expedients permitted under the transition guidance, which among other things, allow us to carry forward the historical accounting relating to lease identification and classification for existing leases upon adoption. We have also elected the practical expedient to not separate lease and non-lease components for the majority of our leases and the election to keep leases with an initial term of 12 months or less off of the consolidated balance sheet.

The cumulative effect of the changes made to our January 1, 2019 consolidated balance sheet for the adoption of ASC 842 were as follows:



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

The adjustment made to the January 1, 2019 consolidated balance sheet related to an accrued liability for lease escalation clauses in certain of our leases under ASC 840 which is a cumulative-effect adjustment to the opening balance of accumulated deficit upon the adoption of ASC 842.

Leases

We have nine total operating leases ~~for ten leased~~which relate to both office space locations and certain office equipment. Our leases have remaining lease terms of 1 year to 6 years. Our leases do not contain any material residual value guarantees or material restricted covenants and we currently have no material sublease arrangements. We have no financing leases as defined under ASC 842.

Total operating lease expense for the three and ~~six~~nine months ended ~~June~~September 30, 2019 is as follows:


	For the three months ended June 30, 2019		For the six months ended June 30, 2019		For the Three Months ended September 30, 2019		For the Nine Months ended September 30, 2019
Operating lease cost	$	171	$	343	$	171	$	514
Short-term lease cost	—		68		1		135
Total lease cost	$	171	$	411	$	172	$	649

The weighted average remaining lease term was ~~4.35~~4.33 years as of ~~June~~September 30, 2019. The weighted average discount rate was ~~3.61%~~3.52% as of ~~June~~September 30, 2019.

Remaining maturities of our existing lease liabilities as of ~~June~~September 30, 2019 were as follows:

The following is the balance sheet classification of our existing lease liabilities as of ~~June~~September 30, 2019:

Supplemental cash flow information related to leases was as follows:

13. Accrued Liabilities

The components of other accrued liabilities are as follows:

14. Contingencies

Fuel Tech is subject to various claims and contingencies related to, among other things, workers compensation, general liability (including product liability), and lawsuits. The Company records liabilities where a contingent loss is probable and can be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when no amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is not probable or the amount is not estimable, or both, if there is a reasonable possibility that a material loss may have been incurred.

From time to time we are involved in litigation with respect to matters arising from the ordinary conduct of our business. In the opinion of management, based upon presently available information, either adequate provision for anticipated costs have been accrued or the ultimate anticipated costs will not materially affect our consolidated financial position, results of operations, or cash flows. We do not believe we have any pending loss contingencies that are probable or reasonably possible of having a material impact on our consolidated financial position, results of operations or cash flows.

During the fourth quarter of 2018, the Company was notified of certain non-conformance issues with a U.S. customer associated with equipment that requires remedy under the warranty provision of the contract. ~~Thus far, the~~The Company is ~~working to resolve~~in the process of remedying the non-conformance ~~issues in an amicable manner.~~issues. During the first quarter of 2019, the Company filed a notice of claim with our

insurance carrier and received a confirmation of insurance coverage. As a result, the company recorded $973 as expected insurance proceeds from our insurance carrier and $1,223 (including the insurance policy deductible of $250) as an accrued liability associated with the ~~completion~~remedy of the non-conformance issues identified with our customer for the three months ended March 31, 2019. During the second quarter of 2019, we revised our claim estimate with our insurance carrier and recorded an additional $1,005 as expected insurance proceeds from our insurance carrier and an additional $1,005 as an accrued liability associated with the completion of the non-conformance issues for the three months ended June 30, 2019. As of ~~June~~September 30, 2019, we have total receivables from the insurance carrier of ~~$1,978~~$1,991 in the accounts receivable line of the Consolidated Balance Sheets and a total accrued liability associated with the completion of the non-conformance issues of ~~$2,228~~$760 in the other accrued liabilities line of the Consolidated Balance Sheets. The Company recorded the ~~proceeds~~amount due from our insurance carrier as our insurance coverage and the terms are not in dispute and the claim submitted is consistent with the terms of insurance coverage provided. The Company currently has $500 of accounts receivable which is past due associated with this project. Upon satisfactory completion of non-conformance issues identified with the customer, the Company expects to collect the remaining accounts receivable due from the customer.

Fuel Tech issues a standard product warranty with the sale of its products to customers. Our recognition of warranty liability is based primarily on analyses of warranty claims experienced in the preceding years as the nature of our historical product sales for which we offer a warranty are substantially unchanged. This approach provides an aggregate warranty accrual that is historically aligned with actual warranty claims experienced.

There was no change in the warranty liability balance during the ~~six~~nine months ended ~~June~~September 30, 2019 and 2018. The warranty liability balance was $159 at ~~June~~September 30, 2019 and 2018.

15. Income Taxes

The Company’s effective tax rate is approximately 0% for the three and ~~six~~nine month periods ended ~~June~~September 30, 2019 and 2018, respectively. The Company's effective tax rate differs from the statutory federal tax rate of 21% for the three and ~~six~~nine month periods ended ~~June~~September 30, 2019 primarily due to a full valuation allowance recorded on our United States, China and Italy deferred tax assets since we cannot anticipate when or if we will have sufficient taxable income to utilize the deferred tax assets in the future. Further, our effective tax rate differs from the statutory federal tax rate due to state taxes, differences between U.S. and foreign tax rates, foreign losses incurred with no related tax benefit, non-deductible commissions, and non-deductible meals and entertainment expenses for the three and ~~six~~nine month periods ended ~~June~~September 30, 2019 and 2018.

On April 3, 2019, the Company received notice from the Internal Revenue Service that our U.S. income tax return for the year ended December 31, 2016 is currently under audit.

Fuel Tech had no unrecognized tax benefits as of ~~June~~September 30, 2019 and December 31, 2018.

16. Goodwill and Other Intangibles

Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. Fuel Tech has two reporting units for goodwill evaluation purposes: the FUEL CHEM^® technology segment and the APC technology segment. There is no goodwill associated with our APC segment. At both ~~June~~September 30, 2019 and December 31, 2018, our entire goodwill balance of $2,116 was allocated to the FUEL CHEM^® technology segment.

Goodwill is allocated to each of our reporting units after considering the nature of the net assets giving rise to the goodwill and how each reporting unit would enjoy the benefits and synergies of the net assets acquired. There were no indications of goodwill impairment in the ~~six~~nine months ended ~~June~~September 30, 2019 and 2018.

Fuel Tech reviews other intangible assets, which include customer lists and relationships, covenants not to compete, patent assets, tradenames, and acquired technologies, for impairment on a recurring basis or when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event that impairment indicators exist, a further analysis is performed and if the sum of the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded. Management considers historical experience and all available information at the time the estimates of future cash flows are made, however, the actual cash values that could be realized may differ from those that are estimated.

During the third quarter of 2019, the Company recorded an abandonment charge of $76 principally associated with the remaining patent assets in China which the Company elected to not maintain and abandon as a result of the planned suspension of the APC business operation in China. The abandonment charge was calculated by determining the net book values of the abandoned patent assets by deducting the accumulated amortization from the acquisition cost. The abandonment charge is included in “Intangible assets abandonment” line in the accompanying Condensed Statements of Operations for the three and nine months ended September 30, 2019.

There were no indications of intangible asset impairments for the ~~six~~nine month period ended ~~June~~September 30, 2019.

FUEL TECH, INC.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Results of Operations

Revenues for the three and ~~six~~nine month periods ending ~~June~~September 30, 2019 and 2018 were ~~$8,948~~$6,452 and ~~$11,847~~$16,070 and ~~$19,103~~$25,555 and ~~$24,638,~~$40,708, respectively, representing a decrease of ~~$2,899~~$9,618 or ~~24%~~60% and ~~$5,535~~$15,153 or ~~22%~~37% versus the same periods last year.

The Air Pollution Control (APC) technology segment generated revenues of ~~$4,803~~$1,816 and ~~$10,592~~$12,408 for the three and ~~six~~nine month periods ending ~~June~~September 30, 2019, representing a decrease of ~~$3,604~~$9,066 or ~~43%~~83% and ~~$6,398~~$15,464 or ~~38%~~55% from the prior year amount of ~~$8,407~~$10,882 and ~~$16,990,~~$27,872, respectively. The decrease in APC revenue was principally related to timing of project execution and the decline in backlog of $12.4 million at December 31, 2018 versus $22.1 million at December 31, 2017, resulting from lower new APC orders announced during 2018 and continuing ~~into~~through the first ~~half~~three quarters of 2019.

Consolidated APC backlog at ~~June~~September 30, 2019 was ~~$7,953~~$6,773 versus backlog at December 31, 2018 of $12,384. Our current backlog consists of U.S. domestic projects totaling ~~$6,422~~$5,423 and international projects totaling ~~$1,531.~~$1,350.

The FUEL CHEM^® technology segment generated revenues of ~~$4,145~~$4,636 and ~~$8,511~~$13,147 for the three and ~~six~~nine months ended ~~June~~September 30, 2019, representing an decrease of $552 or 11% and an increase of ~~$705~~$311 or ~~20% and $863 or 11%~~2% from ~~the~~ the prior year amount of ~~$3,440~~$5,188 and ~~$7,648,~~$12,836, respectively. The decrease in FUEL CHEM revenue for the three months ended September 30, 2019 as compared to the same period of the prior year was due to soft electric demand market and low natural gas prices, which leads to fuel switching, unscheduled outages, and combustion units operating at less than capacity. The increase in FUEL CHEM revenue for the nine months ended September 30, 2019 as compared to the same period of the prior year was principally related to the sale of equipment and installation of two new coal-fired units with a U.S. customer. We remain focused on attracting new customers in our FUEL CHEM business, for both coal and ~~noncoal~~non-coal applications, but our ability to attract new coal customers continues to be affected by the soft electric demand market and fuel switching as a result of low natural gas prices.

Consolidated gross margin percentage for the three month periods ended ~~June~~September 30, 2019 and 2018 was ~~44%~~45% and ~~31%~~34%, respectively, and was ~~41%~~42% and ~~36%~~35% for the ~~six~~nine month periods then ended. The overall increase in gross margin is primarily attributable to the mix between APC and FUEL CHEM revenues recognized during the quarter and to an improvement in APC

gross margin for the three and ~~six~~nine month periods ended ~~June~~September 30, 2019 and 2018 to ~~38%~~34% from 25% and 35% from ~~30%~~28%, respectively. The increase in APC gross margin is primarily due to project mix and timing of execution.

For the FUEL CHEM technology segment, the gross margin percentage ~~increased~~decreased to ~~50%~~49% from ~~48% and 49% and 48%~~51% for the three and ~~six~~nine month periods ended ~~June~~September 30, 2019 due to the customer make-up and its related margin mix profile. The gross margin percentage for the FUEL CHEM technology segment remained consistent at 49% for the three and nine month periods ended September 30, 2018.

Selling, general and administrative expenses (SG&A) were ~~$4,455~~$3,822 and ~~$4,763~~$4,105 for the three month periods ended ~~June~~September 30, 2019 and 2018 and ~~$8,913~~$12,735 and ~~$9,684~~$13,789 for ~~six~~nine month periods ending ~~June~~September 30, 2019 and 2018, respectively. For the three and ~~six~~nine month periods ended ~~June~~September 30, 2019, this represents a decrease of ~~$308~~$283 and ~~$771,~~$1,054, respectively. For the three month period ended ~~June~~September 30, 2019, the decrease is the primary result of a reduction ~~of employee related and other administrative costs of $193, professional and consulting services of $55 and a reduction~~ in administrative costs relating to foreign subsidiaries of ~~$60.~~$375 (largely driven by the suspension of the APC business operation in China), a reduction in other administrative costs relating to agent commissions and travel of $135 offset by an increase in employee related and other administrative costs of $85 and professional and consulting services of $142. For the ~~six~~nine month period ended ~~June~~September 30, 2019 the decrease was primarily the result of a reduction in administrative costs relating to foreign subsidiaries of ~~$583,~~$958, largely driven by the suspension of the APC business operation in China, and a reduction in ~~employee related and~~ other administrative costs primarily relating to agent commissions of ~~$173.~~$96. SG&A as a percentage of revenues increased to 59% from 26% and 50% from ~~40% and 47% from 39%~~34% in the three and ~~six~~nine month periods ending ~~June~~September 30, 2019 and 2018. The increase in SG&A percentage is primarily attributed to the decrease in revenues due to the timing of project execution as well as lower new APC orders announced during 2018 and the first ~~half~~three quarters of 2019.

During the second quarter of 2017, the Company suspended all operations associated with the Fuel Conversion business segment. The activity of the Fuel Conversion discontinued operations consisted primarily of storage costs for holding the ~~certain~~ equipment ~~held in Assets held for sale~~at a third-party location totaling $2 and $21 for the three and ~~six month periods~~nine months ended ~~June~~September 30, 2019 and the gain on sale of $20 recorded in discontinued operations during the third quarter. The activity for the Fuel Conversion discontinued operations consisted of Research and Development, severance and other costs for the three and nine months ended September 30, 2018 of $9$10 and ~~$74 and $19 and $99,~~$109, respectively. The Fuel Conversion business segment had no revenues associated with it. The Fuel Conversion business segment had no revenues associated with it. The overall ~~decline~~reduction in the discontinued operations for the three and ~~six~~nine month period ending ~~June~~September 30, 2019 in comparison to the same period in 2018 is due to the overall wind-down of operations for the Fuel Conversion discontinued ~~operations.~~operations and offset with the gain on sale related to the sale of the remaining equipment in Assets held for sale of $20 recorded in discontinued operations during the third quarter of 2019.

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 ~~$30~~$0 and $0 and $625 and $0 for the three and ~~six~~nine months ended ~~June~~September 30, 2019 and 2018, respectively. The charge consisted primarily of one-time severance payments and the early termination penalty for our lease associated with the suspension of our APC business in China. For further information related to restructuring, refer to Note 5 - Restructuring Activities.

Research and development expenses for the three and ~~six~~nine month periods ended ~~June~~September 30, 2019 was ~~$205~~$352 and ~~$471,~~$823, respectively, and for the same periods in 2018 were ~~$261~~$265 and ~~$549,~~$814, respectively. The expenditures in our research and development expenses

were focused on new product development efforts in the pursuit of commercial applications for technologies outside of our traditional markets, and in the development and analysis of new technologies that could represent incremental market opportunities. This includes water treatment technologies that include DGI™ Dissolved Gas Infusion Systems, an innovative alternative to current aeration technology. This technology has not yet met the criteria to be a separate operating segment under ASC 280 Segment Reporting. This infusion process has a variety of applications in the water and waste water industries, including remediation, treatment, biological activity and wastewater odor management. DGI technology benefits include reduced energy consumption, installation costs, and operating costs, while improving treatment performance.

Income tax expense for the three and ~~six~~nine month periods ended ~~June~~September 30, 2019 and 2018 were $2$21 and $1$0 and $2$23 and $2, respectively. The Company is projecting a consolidated effective tax rate of 0% for 2019 which was lower than the federal income tax rate of 21%. The Company's effective tax rate differs from the statutory federal tax rate of 21% for the three and ~~six~~nine months ended ~~June~~September 30, 2019 primarily due to a full valuation allowance recorded on our United States, China and Italy deferred tax assets since we cannot anticipate when or if we will have sufficient taxable income to utilize the deferred tax assets in the future. Further, our effective tax rate differs from the statutory federal tax rate due to state taxes, differences between U.S. and foreign tax rates, foreign losses incurred with no related tax benefit, non-deductible commissions, and non-deductible meals and entertainment expenses.

Liquidity and Sources of Capital

In connection with the transition to BMO Harris Bank N.A., the Company entered into an amendment under its U.S. Domestic credit facility (the Facility) with JPMorgan Chase Bank, N.A. (JPM Chase) to reduce the maximum revolving credit borrowings from $5,500 to $2,750 and extended the maturity to December 31, 2019. Fuel Tech maintains the use of this Facility for its existing standby letters of credit. The Company intends to transition its existing letters of credit from JPM Chase to BMO Harris Bank, N.A. to not renew the Facility upon its maturity. The Facility is secured by $2,750 in cash held by the Company in a separate restricted use designated JPM Chase deposit account and has the Company’s Italian subsidiary, Fuel Tech S.r.l., as a guarantor. Outstanding borrowings under the Facility bear interest at a rate of LIBOR plus 300 basis points. There are no financial covenants set forth in this amendment to the Facility. As of June 30, 2019 and December 31, 2018, there were no outstanding borrowings on the credit facility.

We continue to monitor our liquidity needs and in response to our continued losses have taken measures to reduce expenses and restructure operations which we feel are necessary to ensure we maintain sufficient working capital and liquidity to operate the business and invest in our future.

We have sustained losses from continuing operations during the ~~six~~nine month period ended ~~June~~September 30, 2019 totaling ~~$2,234.~~$3,512. Our cash used from continuing operations for this same period totaled ~~$2,804.~~$2,320. 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~~September 30, 2019 totaled ~~$14,919~~$15,332 (including restricted cash of ~~$3,255)~~$2,482), and our working capital totaled ~~$21,155.~~$20,143. We do not have any outstanding debt obligations other than for our outstanding letters of credit, and our current credit agreement does not have any financial covenants as we ~~have moved to~~are currently in a ~~cash collateralized line of credit~~Cash Collateral Security agreement with our lender.

We have evaluated our ongoing business needs, and considered the cash requirements of our base business of Air Pollution Control and ~~Fuel Chem,~~FUEL CHEM, as well as our efforts to ~~wind-up our Fuel Conversion business and~~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~~FUEL CHEM business segments, b) current operating structure and expenditure levels, and c) the costs of winding up our Fuel Conversion business and APC operations in China as well as other research and development initiatives.

Based on this analysis, management believes that currently we have sufficient cash and working capital to operate our base APC and ~~Fuel Chem~~FUEL CHEM businesses.

Contingencies and Contractual Obligations

Forward-Looking Statements

This Quarterly Report on Form 10-Q contains “forward-looking statements,” as defined in Section 21E of the Securities Exchange Act of 1934, as amended, which are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and reflect Fuel Tech’s current expectations regarding future growth, results of operations, cash flows, performance and business prospects, and opportunities, as well as assumptions made by, and information currently available to, our management. Fuel Tech has tried to identify forward-looking statements by using words such as “anticipate,” “believe,” “plan,” “expect,” “estimate,” “intend,” “will,” and similar expressions, but these words are not the exclusive means of identifying forward-looking

statements. These statements are based on information currently available to Fuel Tech and are subject to various risks, uncertainties, and other factors, including, but not limited to, those discussed in Fuel Tech’s Annual Report on Form 10-K for the year ended December 31, 2018 in Item 1A under the caption “Risk Factors,” which could cause Fuel Tech’s actual growth, results of operations, financial condition, cash flows, performance and business prospects and opportunities to differ materially from those expressed in, or implied by, these statements. Fuel Tech undertakes no obligation to update such factors or to publicly announce the results of any of the forward-looking statements contained herein to reflect future events, developments, or changed circumstances or for any other reason. Investors are cautioned that all forward-looking statements involve risks and uncertainties, including those detailed in Fuel Tech’s filings with the Securities and Exchange Commission.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Foreign Currency Risk Management

Fuel Tech’s earnings and cash flow are subject to fluctuations due to changes in foreign currency exchange rates. We do not enter into foreign currency forward contracts nor into foreign currency option contracts to manage this risk due to the immaterial nature of the transactions involved.

Fuel Tech is also exposed to changes in interest rates primarily due to its debt ~~facilities~~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, 2019.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Fuel Tech maintains disclosure controls and procedures and internal controls designed to ensure (a) that information required to be disclosed in Fuel Tech’s filings under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and (b) that such information is accumulated and communicated to management, including the principal executive and financial officer, as appropriate to allow timely decisions regarding required disclosure. Fuel Tech’s Chief Executive Officer and principal financial officer have evaluated the Company’s disclosure controls and procedures, as defined in Rules 13a – 15(e) and 15d -15(e) of the Exchange Act, as of the end of the period covered by this report, and they have concluded that these controls and procedures are effective.

Changes in Internal Control over Financial Reporting

Beginning January 1, 2019, we adopted ASC 842 "Leases". It did not have a material impact on our ongoing net income; however, we implemented changes to our processes related to accounting for leases and related internal controls. These changes included the development of new policies related to the new leasing framework, training, ongoing contract review requirements, and gathering of information to comply with disclosure requirements.

There has been no change in the Company's internal control over financial reporting during the quarter covered by this report that has materially affected, or is reasonably likely to materially affect, its internal control over financial reporting.

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, 2018 have not materially changed.
