NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2017

(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 months ended March 31, 2017 are not necessarily indicative of the results to be expected for the full year ending December 31, 2017. 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, 2016 as filed with the Securities and Exchange Commission.

Reclassifications

Certain reclassifications to prior year amounts have been made in the consolidated financial statements to conform to the current year presentation. The Company concluded that it was appropriate to separately present restructuring charges in the Consolidated Statement of Operations. Accordingly, the corresponding reclassification has been made to the Consolidated Statement of Operations for the quarter ended March 31, 2016.

2.    Summary of Significant Accounting Policies

Restricted cash

Restricted cash represents funds that are restricted to satisfy any amount borrowed against the Company's existing revolving credit facility (the Facility) with JPMorgan Chase Bank, N.A. The remaining balance of restricted cash totaling $6,020 will remain through the Maturity Date of the Facility. Refer to Note 8 Debt Financing for further information on the Facility.

Revenue Recognition

Revenues from the sales of chemical products are recorded when title transfers, either at the point of shipment or at the point of destination, depending on the contract with the customer.

Fuel Tech uses the percentage of completion method of accounting for equipment construction and license contracts that are sold within the Air Pollution Control (APC) technology segment. Under the percentage of completion method, revenues are recognized as work is performed based on the relationship between actual construction costs incurred and total estimated costs at completion. Construction costs include all direct costs such as materials, labor, and subcontracting costs, and indirect costs allocable to the particular contract such as indirect labor, tools and equipment, and supplies. Revisions in completion estimates and contract values are made in the period in which the facts giving rise to the revisions become known and can influence the timing of when revenues are recognized under the percentage of completion method of accounting. Such revisions have historically not had a material effect on the amount of revenue recognized. The completed contract method is used for certain contracts that are not long-term in nature or when reasonably dependable estimates of the percentage of completion cannot be made. When the completed contract method is used, revenue and costs are deferred until the contract is substantially complete, which usually occurs upon customer acceptance of the installed product. Provisions are made for estimated losses on uncompleted contracts in the period in which such losses are determined.

5

Fuel Tech’s APC contracts are typically eight to sixteen 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 mathematical 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.

Accounts receivable includes unbilled receivables, representing revenues recognized in excess of billings on uncompleted contracts under the percentage of completion method of accounting. At March 31, 2017 and December 31, 2016, unbilled receivables were approximately $3,711 and $6,755, respectively, and are included in accounts receivable on the consolidated balance sheets. Billings in excess of costs and estimated earnings on uncompleted contracts were $1,720 and $1,730, at March 31, 2017 and December 31, 2016, respectively, and are included in other accrued liabilities on the consolidated balance sheets.

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.

Recently Adopted Accounting Pronouncements

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments in this Update simplify the income tax effects, minimum statutory tax withholding requirements and impact of forfeitures related to how share-based payments are accounted for and presented in the financial statements. ASU 2016-09 is effective for the Company beginning on January 1, 2017. The adoption of ASU 2016-09 did not have a material effect on our earnings, cash flows, or financial position. See Note 7, Stock-Based Compensation, for further discussion.

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This new accounting guidance more clearly articulates the requirements for the measurement and disclosure of inventory. Topic 330, Inventory, currently requires an entity to measure inventory at the lower of cost or market. Market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. This new accounting guidance requires the measurement of inventory at lower of cost and net realizable value. The adoption of ASU 2015-11 is effective for the Company beginning on January 1, 2017 and the adoption did not have a material impact on the Company’s consolidated financial statements.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09 "Revenue from Contracts with Customers" (Topic 606). This new accounting guidance on revenue recognition provides for a single five-step model to be applied to all revenue contracts with customers. The new standard also requires additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. In August 2015, the FASB approved a one-year deferral to January 1, 2018. Early adoption is permitted as of the original effective date. The standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The amendments in this Update increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 will be effective for the Company beginning on January 1, 2019. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.

6

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force). The amendments in this Update require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. ASU 2016-18 will be effective for the Company beginning on January 1, 2018. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in this Update simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. ASU 2017-04 will be effective for the Company beginning on January 1, 2020. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.

3.    Restructuring Activities

In July 2016, the Company reduced its workforce to better align its organizational infrastructure to its revised operating plans. The Company continued to reduce its workforce during Q1 2017. The Company recorded a charge of $61 and $317 for the three-months ending March 31, 2017 and 2016, respectively, in connection with the workforce reduction. The charge consisted primarily of one-time severance payments and benefit continuation costs. The following is a reconciliation of the accrual for the workforce reduction that is included within the "Accrued Liabilities" line of the consolidated balance sheets for the three-months ending March 31, 2017 and 2016:

	Three Months Ended
	2017			2016
Restructuring liability at January 1,	$	309		$	—
Amounts expensed	61			317
Amounts paid	(184		)	(304		)
Restructuring liability at March 31,	$	186		$	13

4.    Accumulated Other Comprehensive Loss

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

	Three Months Ended
	March 31,
	2017			2016
Foreign currency translation
Balance at beginning of period	$	(1,574	)	$	(1,568	)
Other comprehensive loss:
Foreign currency translation adjustments (1)	116			429
Balance at end of period	$	(1,458	)	$	(1,139	)
Available-for-sale marketable securities
Balance at beginning of period	$	6		$	12
Other comprehensive income:
Net unrealized holding gain (loss) (2)	1			(3		)
Balance at end of period	$	7		$	9
Total accumulated other comprehensive loss	$	(1,451	)	$	(1,130	)

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

7

(2) In all periods presented, there were no realized holding gains or losses and therefore no amounts were reclassified to earnings.

5.    Treasury Stock

Common stock held in treasury totaled 374,821 and 354,889 with a cost of $1,237 and $1,214 at March 31, 2017 and December 31, 2016, respectively. These shares were withheld from employees to settle personal tax withholding obligations that arose as a result of restricted stock units that have vested in the periods presented.

6.    Earnings per Share

Basic earnings per share excludes the dilutive effects of stock options, restricted stock units (RSUs), and the nil coupon non-redeemable convertible unsecured loan notes. Diluted earnings per share includes the dilutive effect of the nil coupon non-redeemable convertible unsecured loan notes, RSUs, and unexercised in-the-money stock options, except in periods of net loss where the effect of these instruments is anti-dilutive. Out-of-money stock options are excluded from diluted earnings per share because they are anti-dilutive. For the three months ended March 31, 2017 and 2016, basic earnings per share is equal to diluted earnings per share because all outstanding stock awards and convertible loan notes are considered anti-dilutive during periods of net loss. The following table sets forth the weighted-average shares used in calculating the earnings per share for the months ended March 31, 2017 and 2016.

	Three Months Ended   March 31,
	2017	2016
Basic weighted-average shares	23,472,000	23,184,000
Conversion of unsecured loan notes	—	—
Unexercised options and unvested RSUs	—	—
Diluted weighted-average shares	23,472,000	23,184,000

Fuel Tech had 1,792,000 and 2,070,000 weighted average equity awards outstanding at March 31, 2017 and 2016, 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.

7.    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 4,400,676 shares that may be issued or reserved for awards to participants under the Incentive Plan. As of March 31, 2017, Fuel Tech had 1,289,670 shares available for share-based awards under the 2014 Plan.

We adopted the provisions of ASU 2016-09 as of January 1, 2017. Pursuant to this adoption, we recorded any excess tax benefits within income tax expense for the quarter ended March 31, 2017, where previously these were recorded as increases or decreases to additional paid-in capital. This change has been applied prospectively effective January 1, 2017, and therefore no adjustments were made to prior periods. Given the Company has a full valuation allowance on its deferred tax assets, there were no excess tax benefits to record for the quarter ended March 31, 2017. In addition, we have continued to 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. In accordance with the guidance, we retrospectively reported cash paid on behalf of employees for withholding shares for tax-withholding purposes as a financing activity in the Consolidated Statement of Cash Flows. Additionally, there were no excess tax benefits for the quarter-ended March 31, 2017. Any future excess tax benefits will be classified as an operating activity, applied prospectively. The adoption of this ASU did not result in a material change in our earnings, cash flows, or financial position.

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 month periods ended March 31, 2017 and 2016 were as follows:

8

	Three Months Ended   March 31,
	2017			2016
Stock options and restricted stock units, net of forfeited	$	(10	)	$	461
Tax benefit of stock-based compensation expense	—			—
After-tax effect of stock-based compensation (1)	$	(10	)	$	461

(1) The decrease in stock-based compensation expense is due to the reversal of expense in the first quarter of 2017 associated with certain performance-based RSU grants which did not achieve specified performance criteria.

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.

There was no stock option activity for Fuel Tech’s Incentive Plans for the three months ended March 31, 2017. The Company had 1,039,750 options outstanding and exercisable with a weighted-average exercise price of $8.39 at March 31, 2017 and December 31, 2016. There is no aggregate intrinsic value for the stock options outstanding at March 31, 2017 and December 31, 2016.

As of March 31, 2017, 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 described above, performance-based RSU agreements (the Agreements) are issued annually to our Executive Chairman; President/Chief Executive Officer; Senior Vice President, Fuel Conversion Marketing; Senior Vice President, Treasurer/Chief Financial Officer; and Senior Vice President, General Counsel and Corporate Secretary. The Agreements provide each participating executive the opportunity to earn three types of awards with each award type specifying a targeted number of RSUs that may be granted to each executive based on either the individual performance of the executive or our relative performance compared to a peer group, as determined by the award type. The Compensation Committee of our Board of Directors (the Committee) determines the extent to which, if any, RSUs will be granted based on the achievement of the applicable performance criteria specified in the Agreement. This determination will be made following the completion of the applicable performance period (each a Determination Date). Such performance based awards include the following:

• The first type of award is based on individual performance during the respective calendar year as determined by the Committee based on performance criteria specified in the Agreement. These awards will vest over a three year period beginning on the Determination Date. We estimated the fair value of these performance-based RSU awards on the date of the Agreement using the trading price of the Company’s stock and our estimate of the probability that the specified performance criteria will be met. The fair value measurement and probability estimate will be re-measured each reporting date until the Determination Date, at which time the final award amount will be known. For these job performance-based awards, we amortize compensation costs over the requisite service period, adjusted for estimated forfeitures, for each separately vesting tranche of the award.

9

• The second type of RSU award contains a targeted number of RSUs to be granted based on the Company’s revenue growth relative to a specified peer group during a period of two calendar years. These awards vest 67% on the second anniversary of the Agreement date and 33% on the third anniversary of the Agreement date. We estimated the fair value of these performance-based RSU awards on the Agreement date using the trading price of the Company’s stock on the date of determination and our estimate of the probability that the specified performance criteria will be met. For these revenue growth performance-based awards, we amortize compensation costs over the requisite service period, adjusted for estimated forfeitures, for each separately vesting tranche of the award.

• The third type of RSU award contains a targeted number of RSUs to be granted based on the total shareholder return (TSR) of the Company’s common stock relative to a specified peer group during a period of two calendar years. These awards vest 67% on the second anniversary of the Agreement date and 33% on the third anniversary of the Agreement date. We estimated the fair value of these market-based RSU awards on the Agreement date using a Monte Carlo valuation methodology and amortize the fair value over the requisite service period for each separately vesting tranche of the award. The principal variable assumptions utilized in valuing these RSUs under this valuation methodology include the risk-free interest rate, stock volatility, and correlations between our stock price and the stock prices of a peer group of companies.

At March 31, 2017, there is $1,051 of unrecognized compensation costs related to restricted stock unit awards to be recognized over a weighted average period of 1.59 years.

A summary of restricted stock unit activity for the three months ended March 31, 2017 is as follows:

	Shares		Weighted Average Grant Date Fair Value
Unvested restricted stock units at January 1, 2017	1,463,796		$	2.82
Granted	—		—
Forfeited	(200,000	)	3.03
Vested	(113,332	)	4.28
Unvested restricted stock units at March 31, 2017	1,150,464		$	2.64

The fair value of restricted stock that vested during the three month period ending March 31, 2017 was $131.

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. In the three-month periods ended March 31, 2017 and 2016, Fuel Tech recorded no stock-based compensation expense under the Deferred Plan.

8.    Debt Financing

On May 9, 2016, the Company amended its existing U.S. Domestic credit facility with JPM Chase such that the financial covenants as set forth in the credit agreement would not be measured for the period ending as of March 31, 2016, and were removed in their entirety from the Facility. The credit availability under the Facility has been reduced from $15,000 to $7,000 with this amendment, and further, JPM Chase's then current Revolving Commitment under the Facility is now secured by cash held by the Company in a separate restricted use designated JPM Chase deposit account. The amount of credit available to the Company under the Facility was $7,000 from the date of the effective date of the amended facility through May 31, 2016, at which time the credit available to the Company under the Facility was reduced to $6,000 from June 1, 2016 through July 31, 2016, at which time the credit available to the Company under the Facility was reduced to $5,000 and will remain as such until the Maturity Date of the Facility on June 30, 2017. The Company intends to renew the U.S. Domestic credit facility at its maturity. During the entire period of the Facility the Company must maintain sufficient cash balances in a segregated deposit account equal to the amount of the Facility and will fully pledge such cash as collateral to the bank to support the credit available to the Company under the Facility. As of March 31, 2017 and December 31, 2016, there were no outstanding borrowings on the credit facility.

At March 31, 2017 and December 31, 2016, the Company had outstanding standby letters of credit and bank guarantees totaling approximately $3,185 and $3,292, respectively, under the Facility in connection with contracts in process. Fuel Tech is committed to reimbursing the issuing bank for any payments made by the bank under these instruments. The Company pays a commitment fee of 0.25% per year on the unused portion of the revolving credit facility. At March 31, 2017 and December 31, 2016, approximately $1,815 and $1,708 was available for future borrowings under the Facility.

10

On June 24, 2016, Beijing Fuel Tech Environmental Technologies Company, Ltd. (Beijing Fuel Tech), a wholly-owned subsidiary of Fuel Tech, entered into a new revolving credit facility (the China Facility) agreement with JPM Chase for RMB 6.5 million (approximately $943), which expires on June 23, 2017. The Company intends to renew the China Facility at its maturity. This new credit facility replaced the previous RMB 35 million facility that expired on June 24, 2016. The facility is unsecured, bears interest at a rate of 125% of the People’s Bank of China (PBOC) Base Rate, and is guaranteed by Fuel Tech. Beijing Fuel Tech can use this facility for cash advances and bank guarantees. As of March 31, 2017 and December 31, 2016, Beijing Fuel Tech had no cash borrowings under the China Facility.

At March 31, 2017 and December 31, 2016, the Company had outstanding standby letters of credit and bank guarantees totaling approximately $22 and $22, respectively, on its Beijing Fuel Tech revolving credit facility in connection with contracts in process. At March 31, 2017 and December 31, 2016, approximately $921 and $914 was available for future borrowings.

In the event of default on either the domestic facility or the China facility, the cross default feature in each allows the lending bank to accelerate the payments of any amounts outstanding and may, under certain circumstances, allow the bank to cancel the facility. If the Company were unable to obtain a waiver for a breach of covenant and the bank accelerated the payment of any outstanding amounts, such acceleration may cause the Company’s cash position to deteriorate or, if cash on hand were insufficient to satisfy the payment due, may require the Company to obtain alternate financing to satisfy the accelerated payment.

9.    Business Segment and Geographic Financial Data

Business Segment Financial Data

We segregate our financial results into three reportable segments representing three 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 Fuel Conversion segment represents a new business initiative we commenced in 2014. We acquired intellectual property rights and know-how related to the CARBONITE® fuel conversion process and technology. This process can convert coals of various grades into value-added products that are high in energy content, carbon-rich and less pollutive. This technology has a number of potential applications including certain coal replacement, electric arc furnace (EAF) reductant, ferro-alloy feedstock, absorbent and Hg reduced carbon stock. During 2015 and 2016, we have been testing and developing the engineered carbon products for specific markets. We are in the process of evaluating the commercialization of these product offerings with prospective customers and considering alternatives. We have earned no significant revenue other than for test products from perspective customers for the three-months ended March 31, 2017 and 2016.

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 are provided below:

10.    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.

During the second quarter of 2016, the Company received a notice from a contractor that performed installation work on one of the Company's APC projects regarding $3.9 million in purported expenses beyond the contractually agreed cap on expenses. The Company initiated the process, as required by the Company's contract with the subcontractor, to submit the dispute into mediation. On March 2, 2017, the Company agreed to a final settlement with the subcontractor of $1,150 and the full amount is included in the accrued liabilities line of the consolidated balance sheet as of December 31, 2016. The full amount was paid during March 2017.

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.

Changes in the warranty liability for the three months March 31, 2017 and 2016, are summarized below:

	Three Months Ended   March 31,
	2017		2016
Aggregate product warranty liability at beginning of period	$	159	$	268
Net aggregate (benefit) related to product warranties	—		(109		)
Aggregate reductions for payments	—		—
Aggregate product warranty liability at end of period	$	159	$	159

11.    Income Taxes

The Company’s effective tax rate is 0% and (7)% for the three-month periods ended March 31, 2017 and 2016, respectively. The Company's effective tax rate differs from the statutory federal tax rate of 34% for the three-month period ended March 31, 2017 primarily due to a full valuation allowance recorded on our United States, China and Italy deferred tax assets since we cannot anticipate when or if we will have sufficient taxable income to utilize the deferred tax assets in the future. Further, our effective tax rate differs from the statutory federal tax rate due to state taxes, differences between U.S. and foreign tax rates, foreign losses incurred with no related tax benefit, non-deductible commissions, and non-deductible meals and entertainment expenses for the three-month periods ended March 31, 2017 and 2016, respectively.

Fuel Tech had no unrecognized tax benefits as of March 31, 2017 and December 31, 2016.  

12.    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 or Fuel Conversion segments.  At both March 31, 2017 and December 31, 2016, our entire goodwill balance of $2,116 was allocated to the FUEL CHEM^® technology segment.

Goodwill is allocated to each of our reporting units after considering the nature of the net assets giving rise to the goodwill and how each reporting unit would enjoy the benefits and synergies of the net assets acquired. There were no indications of goodwill impairment in the three months ended March 31, 2017 and 2016.

Fuel Tech reviews other intangible assets, which include customer lists and relationships, covenants not to compete, patent assets, tradenames, and acquired technologies, for impairment on a recurring basis or when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event that impairment indicators exist, a further analysis is performed and if the sum of the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded. Management considers historical experience and all available information at the time the estimates of future cash flows are made, however, the actual cash values that could be realized may differ from those that are estimated. There were no indications of intangible asset impairment in the three-month periods ended March 31, 2017 and 2016.

FUEL TECH, INC.

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

Results of Operations

Revenues for the three-month periods ending March 31, 2017 and 2016 were $8,491 and $17,822, respectively, representing a current year decrease of $9,331 or 52%.

The Air Pollution Control (APC) technology segment generated revenues of $4,002 for the three-month period ending March 31, 2017, representing a decrease of $8,988 or 69% from the prior year amount of $12,990. The decrease in APC revenue was principally related to historically low backlog of $8,030 at December 31, 2016. Revenues in our APC technology segment, which had been growing into 2013 largely through international sales, are adversely affected by a number of factors. First, the U.S. regulatory environment, while remaining favorable for our prospects, has not spurred capital investment in our products by electric power producers. Second, while general economic conditions in the U.S. have improved, energy demand for coal fired power plants has declined as utilities have switched to lower cost natural gas sources. At the same time, these sources have generally allowed utilities to meet their regulatory objectives with existing emissions investments. Sales in foreign locations have not been robust enough to offset reduced demand in the U.S.

Consolidated APC backlog at March 31, 2017 was $22,462 versus backlog at December 31, 2016 of $8,030. Our current backlog consists of U.S. domestic projects totaling $11,266 and international projects totaling $11,196.

The FUEL CHEM^® technology segment generated revenues of $4,489 for the three-months ended March 31, 2017, representing a decrease of $343 or 7% versus the prior year amount of $4,832. This segment continues to be affected by the soft electric demand market and low natural gas prices, which leads to fuel switching, unscheduled outages, and combustion units operating at less than capacity.

Consolidated gross margin percentage for the three-months ended March 31, 2017 was 44%, up 10% from the prior year percentage of 34%. The gross margin percentage for the APC technology segment for the three-month periods ended March 31, 2017 and 2016 was 38% and 28%, respectively. For the FUEL CHEM technology segment, the gross margin percentage was 49% for both the three-month periods ending March 31, 2017 and 2016.

Selling, general and administrative expenses (SG&A) for the three months ended March 31, 2017 was $5,154, which represents a decrease of $2,008 from the prior year amount of $7,162. This change resulted from a decrease in employee related costs of $949, administrative costs associated with our domestic and foreign operations of $399, professional and consulting services of $185, and other administrative expenses of $475. The increase in SG&A percentage is attributed to the decrease in revenues due to soft electric demand and low natural gas prices.

In early 2016, the Company reduced its workforce to better align its organizational infrastructure to its revised operating plans. The Company recorded a charge of $61 and $317 for the three months ending March 31, 2017 and 2016, respectively, in connection with the workforce reduction. The charge consisted primarily of one-time severance payments and benefit continuation costs. For further information related to restructuring, refer to Note 3 - Restructuring Activities.

Research and development expenses for the three months ended March 31, 2017 was $1,014, representing a decrease of $144 over the prior year amount of $1,158. In our Research and development expenses for the three months ended March 31, 2017 were $730 in expenses pertaining to the development of our Fuel Conversion business, while the remaining expenditures were focused on new product development for our APC and Fuel Chem businesses. We plan to continue focusing on increased research and 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.

Income tax benefit for the three months ended March 31, 2017 and 2016 were $0 and $205, respectively. The Company is projecting a consolidated effective tax rate of 0% for 2017 which was lower than the federal income tax rate of 34%. The Company's effective tax rate differs from the statutory federal tax rate of 34% for the three months ended March 31, 2017 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

12

At March 31, 2017, Fuel Tech had unrestricted cash and cash equivalents and short-term investments on hand of $10,203 (excluding restricted cash of $6,020) and working capital of $24,890 versus $11,826 (excluding restricted cash of $6,020) and $26,585 at December 31, 2016, respectively.

Operating activities used cash of $1,620 during the three-month period ended March 31, 2017. This decrease in cash from operations was due to our net loss of $2,506, a decrease in accounts payable and accrued expenses of $3,331, and an increase in inventory of $26, offset by cash provided by a decrease in our accounts receivable of $3,525, a decrease in prepaid and other assets of $108, and the effect of non-cash charges of $610.

Investing activities used cash of $97 during the three-month period ended March 31, 2017 and related to net cash used for purchases of equipment and patents.

Financing activities used cash of $23 during the three months ended March 31, 2017 all of which related to cash used for the acquisition of common shares held in treasury that were withheld for taxes due by employees upon vesting of restricted stock units.

On May 9, 2016, the Company amended its existing U.S. Domestic credit facility with JPM Chase such that the financial covenants as set forth in the credit agreement would not be measured for the period ending as of March 31, 2016, and were removed in their entirety from the Facility. The credit availability under the Facility has been reduced from $15,000 to $7,000 with this amendment, and further, JPM Chase's then current Revolving Commitment under the Facility is now secured by cash held by the Company in a separate restricted use designated JPM Chase deposit account. The amount of credit available to the Company under the Facility was $7,000 from the date of the effective date of the amended facility through May 31, 2016, at which time the credit available to the Company under the Facility was reduced to $6,000 from June 1, 2016 through July 31, 2016, at which time the credit available to the Company under the Facility was reduced to $5,000 and will remain as such until the Maturity Date of the Facility on June 30, 2017. The Company intends to renew the U.S. Domestic credit facility at its maturity. During the entire period of the Facility the Company must maintain sufficient cash balances in a segregated deposit account equal to the amount of the Facility and will fully pledge such cash as collateral to the bank to support the credit available to the Company under the Facility. As of March 31, 2017 and December 31, 2016, there were no outstanding borrowings on the credit facility.

At March 31, 2017 and December 31, 2016, the Company had outstanding standby letters of credit and bank guarantees totaling approximately $3,185 and $3,292, respectively, under the Facility in connection with contracts in process. Fuel Tech is committed to reimbursing the issuing bank for any payments made by the bank under these instruments. The Company pays a commitment fee of 0.25% per year on the unused portion of the revolving credit facility. At March 31, 2017 and December 31, 2016, approximately $1,815 and $1,708 was available for future borrowings under the Facility.

On June 24, 2016, Beijing Fuel Tech Environmental Technologies Company, Ltd. (Beijing Fuel Tech), a wholly-owned subsidiary of Fuel Tech, entered into a new revolving credit facility (the China Facility) agreement with JPM Chase for RMB 6.5 million (approximately $943), which expires on June 23, 2017. The Company intends to renew the China Facility at its maturity. This new credit facility replaced the previous RMB 35 million facility that expired on June 24, 2016. The facility is unsecured, bears interest at a rate of 125% of the People’s Bank of China (PBOC) Base Rate, and is guaranteed by Fuel Tech. Beijing Fuel Tech can use this facility for cash advances and bank guarantees. As of March 31, 2017 and December 31, 2016, Beijing Fuel Tech had no cash borrowings under the China Facility.

At March 31, 2017 and December 31, 2016, the Company had outstanding standby letters of credit and bank guarantees totaling approximately $22 and $22, respectively, on its Beijing Fuel Tech revolving credit facility in connection with contracts in process. At March 31, 2017 and December 31, 2016, approximately $921 and $914 was available for future borrowings.

In the event of default on either the domestic facility or the China facility, the cross default feature in each allows the lending bank to accelerate the payments of any amounts outstanding and may, under certain circumstances, allow the bank to cancel the facility. If the Company were unable to obtain a waiver for a breach of covenant and the bank accelerated the payment of any outstanding amounts, such acceleration may cause the Company’s cash position to deteriorate or, if cash on hand were insufficient to satisfy the payment due, may require the Company to obtain alternate financing to satisfy the accelerated payment.

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

We have sustained losses for the first three months of 2017 totaling $2,506. Our cash used in operations for this same period totaled $1,620. We incur on an annualized basis approximately $5.5 million in non-cash expenses for depreciation, amortization and stock

13

compensation. We have taken measures to reduce our expense infrastructure, and over the past two years have eliminated approximately $8 million in aggregate expense through headcount and other operating expense cutbacks.

Our cash balance as of March 31, 2017 totaled $16,234, and our working capital totaled $24,890. We do not have any outstanding debt obligations other than our letters of credit, and our current credit agreement does not have any financial covenants as we have moved to a cash collateralized line of credit with our lender.

We have evaluated our ongoing business needs, and considered the cash requirements of our base business of Air Pollution Control and Fuel Chem, as well as our efforts to support our Fuel Conversion business. 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) support for our Fuel Conversion business and other research and development initiatives.

We currently have a $5 million domestic U.S. credit facility which we use to issue letters of credit to our customers. During 2016 that credit facility was converted to a fully cash collateralized line of credit requiring us to deposit funds in a restricted cash account to support that credit line. We expect to continue operating under this arrangement for the foreseeable future. Our liquidity may be adversely affected to the extent we are required to collateralize further letters of credit by additional cash deposits.

Based on this analysis, management believes that currently we have sufficient cash and working capital to operate our base APC and Fuel Chem businesses. However, we do not have sufficient capital to support the full development of our Fuel Conversion business for the longer term that will require us to find outside resources to support this business effort. No assurances can be given as to whether such resources will be available, or on what terms.

Contingencies and Contractual Obligations

Fuel Tech issues a standard product warranty with the sale of its products to customers as discussed in Note 10. There was no change in the warranty liability balance during the three-months ended March 31, 2017.

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, 2016 in Item 1A under the caption “Risk Factors,” which could cause Fuel Tech’s actual growth, results of operations, financial condition, cash flows, performance and business prospects and opportunities to differ materially from those expressed in, or implied by, these statements. Fuel Tech undertakes no obligation to update such factors or to publicly announce the results of any of the forward-looking statements contained herein to reflect future events, developments, or changed circumstances or for any other reason. Investors are cautioned that all forward-looking statements involve risks and uncertainties, including those detailed in Fuel Tech’s filings with the Securities and Exchange Commission.

Item 3.        Quantitative and Qualitative Disclosures about Market Risk

Foreign Currency Risk Management

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

Fuel Tech is also exposed to changes in interest rates primarily due to its debt facilities (refer to Note 8 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, 2017.

Item 4.        Controls and Procedures

Evaluation of Disclosure Controls and Procedures

14

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 Chief 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

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 months ended March 31, 2017 are not necessarily indicative of the results to be expected for the full year ending December 31, 2017. 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, 2016 as filed with the Securities and Exchange Commission.

Reclassifications

Certain reclassifications to prior year amounts have been made in the consolidated financial statements to conform to the current year presentation. The Company concluded that it was appropriate to separately present restructuring charges in the Consolidated Statement of Operations. Accordingly, the corresponding reclassification has been made to the Consolidated Statement of Operations for the quarter ended March 31, 2016.

Summary of Significant Accounting Policies

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Restricted cash

Restricted cash represents funds that are restricted to satisfy any amount borrowed against the Company's existing revolving credit facility (the Facility) with JPMorgan Chase Bank, N.A. The remaining balance of restricted cash totaling $6,020 will remain through the Maturity Date of the Facility. Refer to Note 8 Debt Financing for further information on the Facility.

Revenue Recognition

Revenues from the sales of chemical products are recorded when title transfers, either at the point of shipment or at the point of destination, depending on the contract with the customer.

Fuel Tech uses the percentage of completion method of accounting for equipment construction and license contracts that are sold within the Air Pollution Control (APC) technology segment. Under the percentage of completion method, revenues are recognized as work is performed based on the relationship between actual construction costs incurred and total estimated costs at completion. Construction costs include all direct costs such as materials, labor, and subcontracting costs, and indirect costs allocable to the particular contract such as indirect labor, tools and equipment, and supplies. Revisions in completion estimates and contract values are made in the period in which the facts giving rise to the revisions become known and can influence the timing of when revenues are recognized under the percentage of completion method of accounting. Such revisions have historically not had a material effect on the amount of revenue recognized. The completed contract method is used for certain contracts that are not long-term in nature or when reasonably dependable estimates of the percentage of completion cannot be made. When the completed contract method is used, revenue and costs are deferred until the contract is substantially complete, which usually occurs upon customer acceptance of the installed product. Provisions are made for estimated losses on uncompleted contracts in the period in which such losses are determined.

Fuel Tech’s APC contracts are typically eight to sixteen 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 mathematical 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.

Accounts receivable includes unbilled receivables, representing revenues recognized in excess of billings on uncompleted contracts under the percentage of completion method of accounting. At March 31, 2017 and December 31, 2016, unbilled receivables were approximately $3,711 and $6,755, respectively, and are included in accounts receivable on the consolidated balance sheets. Billings in excess of costs and estimated earnings on uncompleted contracts were $1,720 and $1,730, at March 31, 2017 and December 31, 2016, respectively, and are included in other accrued liabilities on the consolidated balance sheets.

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.

Recently Adopted Accounting Pronouncements

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments in this Update simplify the income tax effects, minimum statutory tax withholding requirements and impact of forfeitures related to how share-based payments are accounted for and presented in the financial statements. ASU 2016-09 is effective for the Company beginning on January 1, 2017. The adoption of ASU 2016-09 did not have a material effect on our earnings, cash flows, or financial position. See Note 7, Stock-Based Compensation, for further discussion.

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This new accounting guidance more clearly articulates the requirements for the measurement and disclosure of inventory. Topic 330, Inventory, currently requires an entity to measure inventory at the lower of cost or market. Market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. This new accounting guidance requires the measurement of inventory at lower of cost and net realizable value. The adoption of ASU 2015-11 is effective for the Company beginning on January 1, 2017 and the adoption did not have a material impact on the Company’s consolidated financial statements.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09 "Revenue from Contracts with Customers" (Topic 606). This new accounting guidance on revenue recognition provides for a single five-step model to be applied to all revenue contracts with customers. The new standard also requires additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. In August 2015, the FASB approved a one-year deferral to January 1, 2018. Early adoption is permitted as of the original effective date. The standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The amendments in this Update increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 will be effective for the Company beginning on January 1, 2019. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force). The amendments in this Update require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. ASU 2016-18 will be effective for the Company beginning on January 1, 2018. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in this Update simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. ASU 2017-04 will be effective for the Company beginning on January 1, 2020. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.

Earnings Per Share [Abstract]

Earnings per Share

Earnings per Share

Basic earnings per share excludes the dilutive effects of stock options, restricted stock units (RSUs), and the nil coupon non-redeemable convertible unsecured loan notes. Diluted earnings per share includes the dilutive effect of the nil coupon non-redeemable convertible unsecured loan notes, RSUs, and unexercised in-the-money stock options, except in periods of net loss where the effect of these instruments is anti-dilutive. Out-of-money stock options are excluded from diluted earnings per share because they are anti-dilutive. For the three months ended March 31, 2017 and 2016, basic earnings per share is equal to diluted earnings per share because all outstanding stock awards and convertible loan notes are considered anti-dilutive during periods of net loss. The following table sets forth the weighted-average shares used in calculating the earnings per share for the months ended March 31, 2017 and 2016.

	Three Months Ended   March 31,
	2017	2016
Basic weighted-average shares	23,472,000	23,184,000
Conversion of unsecured loan notes	—	—
Unexercised options and unvested RSUs	—	—
Diluted weighted-average shares	23,472,000	23,184,000

Fuel Tech had 1,792,000 and 2,070,000 weighted average equity awards outstanding at March 31, 2017 and 2016, 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.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

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 4,400,676 shares that may be issued or reserved for awards to participants under the Incentive Plan. As of March 31, 2017, Fuel Tech had 1,289,670 shares available for share-based awards under the 2014 Plan.

We adopted the provisions of ASU 2016-09 as of January 1, 2017. Pursuant to this adoption, we recorded any excess tax benefits within income tax expense for the quarter ended March 31, 2017, where previously these were recorded as increases or decreases to additional paid-in capital. This change has been applied prospectively effective January 1, 2017, and therefore no adjustments were made to prior periods. Given the Company has a full valuation allowance on its deferred tax assets, there were no excess tax benefits to record for the quarter ended March 31, 2017. In addition, we have continued to 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. In accordance with the guidance, we retrospectively reported cash paid on behalf of employees for withholding shares for tax-withholding purposes as a financing activity in the Consolidated Statement of Cash Flows. Additionally, there were no excess tax benefits for the quarter-ended March 31, 2017. Any future excess tax benefits will be classified as an operating activity, applied prospectively. The adoption of this ASU did not result in a material change in our earnings, cash flows, or financial position.

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 month periods ended March 31, 2017 and 2016 were as follows:

	Three Months Ended   March 31,
	2017			2016
Stock options and restricted stock units, net of forfeited	$	(10	)	$	461
Tax benefit of stock-based compensation expense	—			—
After-tax effect of stock-based compensation (1)	$	(10	)	$	461

(1) The decrease in stock-based compensation expense is due to the reversal of expense in the first quarter of 2017 associated with certain performance-based RSU grants which did not achieve specified performance criteria.

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.

There was no stock option activity for Fuel Tech’s Incentive Plans for the three months ended March 31, 2017. The Company had 1,039,750 options outstanding and exercisable with a weighted-average exercise price of $8.39 at March 31, 2017 and December 31, 2016. There is no aggregate intrinsic value for the stock options outstanding at March 31, 2017 and December 31, 2016.

As of March 31, 2017, 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 described above, performance-based RSU agreements (the Agreements) are issued annually to our Executive Chairman; President/Chief Executive Officer; Senior Vice President, Fuel Conversion Marketing; Senior Vice President, Treasurer/Chief Financial Officer; and Senior Vice President, General Counsel and Corporate Secretary. The Agreements provide each participating executive the opportunity to earn three types of awards with each award type specifying a targeted number of RSUs that may be granted to each executive based on either the individual performance of the executive or our relative performance compared to a peer group, as determined by the award type. The Compensation Committee of our Board of Directors (the Committee) determines the extent to which, if any, RSUs will be granted based on the achievement of the applicable performance criteria specified in the Agreement. This determination will be made following the completion of the applicable performance period (each a Determination Date). Such performance based awards include the following:

• The first type of award is based on individual performance during the respective calendar year as determined by the Committee based on performance criteria specified in the Agreement. These awards will vest over a three year period beginning on the Determination Date. We estimated the fair value of these performance-based RSU awards on the date of the Agreement using the trading price of the Company’s stock and our estimate of the probability that the specified performance criteria will be met. The fair value measurement and probability estimate will be re-measured each reporting date until the Determination Date, at which time the final award amount will be known. For these job performance-based awards, we amortize compensation costs over the requisite service period, adjusted for estimated forfeitures, for each separately vesting tranche of the award.

• The second type of RSU award contains a targeted number of RSUs to be granted based on the Company’s revenue growth relative to a specified peer group during a period of two calendar years. These awards vest 67% on the second anniversary of the Agreement date and 33% on the third anniversary of the Agreement date. We estimated the fair value of these performance-based RSU awards on the Agreement date using the trading price of the Company’s stock on the date of determination and our estimate of the probability that the specified performance criteria will be met. For these revenue growth performance-based awards, we amortize compensation costs over the requisite service period, adjusted for estimated forfeitures, for each separately vesting tranche of the award.

• The third type of RSU award contains a targeted number of RSUs to be granted based on the total shareholder return (TSR) of the Company’s common stock relative to a specified peer group during a period of two calendar years. These awards vest 67% on the second anniversary of the Agreement date and 33% on the third anniversary of the Agreement date. We estimated the fair value of these market-based RSU awards on the Agreement date using a Monte Carlo valuation methodology and amortize the fair value over the requisite service period for each separately vesting tranche of the award. The principal variable assumptions utilized in valuing these RSUs under this valuation methodology include the risk-free interest rate, stock volatility, and correlations between our stock price and the stock prices of a peer group of companies.

At March 31, 2017, there is $1,051 of unrecognized compensation costs related to restricted stock unit awards to be recognized over a weighted average period of 1.59 years.

A summary of restricted stock unit activity for the three months ended March 31, 2017 is as follows:

	Shares		Weighted Average Grant Date Fair Value
Unvested restricted stock units at January 1, 2017	1,463,796		$	2.82
Granted	—		—
Forfeited	(200,000	)	3.03
Vested	(113,332	)	4.28
Unvested restricted stock units at March 31, 2017	1,150,464		$	2.64

The fair value of restricted stock that vested during the three month period ending March 31, 2017 was $131.

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. In the three-month periods ended March 31, 2017 and 2016, Fuel Tech recorded no stock-based compensation expense under the Deferred Plan.

Debt Financing

On May 9, 2016, the Company amended its existing U.S. Domestic credit facility with JPM Chase such that the financial covenants as set forth in the credit agreement would not be measured for the period ending as of March 31, 2016, and were removed in their entirety from the Facility. The credit availability under the Facility has been reduced from $15,000 to $7,000 with this amendment, and further, JPM Chase's then current Revolving Commitment under the Facility is now secured by cash held by the Company in a separate restricted use designated JPM Chase deposit account. The amount of credit available to the Company under the Facility was $7,000 from the date of the effective date of the amended facility through May 31, 2016, at which time the credit available to the Company under the Facility was reduced to $6,000 from June 1, 2016 through July 31, 2016, at which time the credit available to the Company under the Facility was reduced to $5,000 and will remain as such until the Maturity Date of the Facility on June 30, 2017. The Company intends to renew the U.S. Domestic credit facility at its maturity. During the entire period of the Facility the Company must maintain sufficient cash balances in a segregated deposit account equal to the amount of the Facility and will fully pledge such cash as collateral to the bank to support the credit available to the Company under the Facility. As of March 31, 2017 and December 31, 2016, there were no outstanding borrowings on the credit facility.

At March 31, 2017 and December 31, 2016, the Company had outstanding standby letters of credit and bank guarantees totaling approximately $3,185 and $3,292, respectively, under the Facility in connection with contracts in process. Fuel Tech is committed to reimbursing the issuing bank for any payments made by the bank under these instruments. The Company pays a commitment fee of 0.25% per year on the unused portion of the revolving credit facility. At March 31, 2017 and December 31, 2016, approximately $1,815 and $1,708 was available for future borrowings under the Facility.

On June 24, 2016, Beijing Fuel Tech Environmental Technologies Company, Ltd. (Beijing Fuel Tech), a wholly-owned subsidiary of Fuel Tech, entered into a new revolving credit facility (the China Facility) agreement with JPM Chase for RMB 6.5 million (approximately $943), which expires on June 23, 2017. The Company intends to renew the China Facility at its maturity. This new credit facility replaced the previous RMB 35 million facility that expired on June 24, 2016. The facility is unsecured, bears interest at a rate of 125% of the People’s Bank of China (PBOC) Base Rate, and is guaranteed by Fuel Tech. Beijing Fuel Tech can use this facility for cash advances and bank guarantees. As of March 31, 2017 and December 31, 2016, Beijing Fuel Tech had no cash borrowings under the China Facility.

At March 31, 2017 and December 31, 2016, the Company had outstanding standby letters of credit and bank guarantees totaling approximately $22 and $22, respectively, on its Beijing Fuel Tech revolving credit facility in connection with contracts in process. At March 31, 2017 and December 31, 2016, approximately $921 and $914 was available for future borrowings.

In the event of default on either the domestic facility or the China facility, the cross default feature in each allows the lending bank to accelerate the payments of any amounts outstanding and may, under certain circumstances, allow the bank to cancel the facility. If the Company were unable to obtain a waiver for a breach of covenant and the bank accelerated the payment of any outstanding amounts, such acceleration may cause the Company’s cash position to deteriorate or, if cash on hand were insufficient to satisfy the payment due, may require the Company to obtain alternate financing to satisfy the accelerated payment.

Business Segment and Geographic Financial Data

Business Segment Financial Data

We segregate our financial results into three reportable segments representing three 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 Fuel Conversion segment represents a new business initiative we commenced in 2014. We acquired intellectual property rights and know-how related to the CARBONITE® fuel conversion process and technology. This process can convert coals of various grades into value-added products that are high in energy content, carbon-rich and less pollutive. This technology has a number of potential applications including certain coal replacement, electric arc furnace (EAF) reductant, ferro-alloy feedstock, absorbent and Hg reduced carbon stock. During 2015 and 2016, we have been testing and developing the engineered carbon products for specific markets. We are in the process of evaluating the commercialization of these product offerings with prospective customers and considering alternatives. We have earned no significant revenue other than for test products from perspective customers for the three-months ended March 31, 2017 and 2016.

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.

Contingencies

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.

During the second quarter of 2016, the Company received a notice from a contractor that performed installation work on one of the Company's APC projects regarding $3.9 million in purported expenses beyond the contractually agreed cap on expenses. The Company initiated the process, as required by the Company's contract with the subcontractor, to submit the dispute into mediation. On March 2, 2017, the Company agreed to a final settlement with the subcontractor of $1,150 and the full amount is included in the accrued liabilities line of the consolidated balance sheet as of December 31, 2016. The full amount was paid during March 2017.

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.

Changes in the warranty liability for the three months March 31, 2017 and 2016, are summarized below:

Income Taxes

Income Taxes

The Company’s effective tax rate is 0% and (7)% for the three-month periods ended March 31, 2017 and 2016, respectively. The Company's effective tax rate differs from the statutory federal tax rate of 34% for the three-month period ended March 31, 2017 primarily due to a full valuation allowance recorded on our United States, China and Italy deferred tax assets since we cannot anticipate when or if we will have sufficient taxable income to utilize the deferred tax assets in the future. Further, our effective tax rate differs from the statutory federal tax rate due to state taxes, differences between U.S. and foreign tax rates, foreign losses incurred with no related tax benefit, non-deductible commissions, and non-deductible meals and entertainment expenses for the three-month periods ended March 31, 2017 and 2016, respectively.

Fuel Tech had no unrecognized tax benefits as of March 31, 2017 and December 31, 2016.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Other Intangibles

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 or Fuel Conversion segments.  At both March 31, 2017 and December 31, 2016, our entire goodwill balance of $2,116 was allocated to the FUEL CHEM^® technology segment.

Goodwill is allocated to each of our reporting units after considering the nature of the net assets giving rise to the goodwill and how each reporting unit would enjoy the benefits and synergies of the net assets acquired. There were no indications of goodwill impairment in the three months ended March 31, 2017 and 2016.

Fuel Tech reviews other intangible assets, which include customer lists and relationships, covenants not to compete, patent assets, tradenames, and acquired technologies, for impairment on a recurring basis or when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event that impairment indicators exist, a further analysis is performed and if the sum of the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded. Management considers historical experience and all available information at the time the estimates of future cash flows are made, however, the actual cash values that could be realized may differ from those that are estimated. There were no indications of intangible asset impairment in the three-month periods ended March 31, 2017 and 2016.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2017

Accounting Policies [Abstract]

Revenue Recognition Policy

Revenues from the sales of chemical products are recorded when title transfers, either at the point of shipment or at the point of destination, depending on the contract with the customer.

Fuel Tech uses the percentage of completion method of accounting for equipment construction and license contracts that are sold within the Air Pollution Control (APC) technology segment. Under the percentage of completion method, revenues are recognized as work is performed based on the relationship between actual construction costs incurred and total estimated costs at completion. Construction costs include all direct costs such as materials, labor, and subcontracting costs, and indirect costs allocable to the particular contract such as indirect labor, tools and equipment, and supplies. Revisions in completion estimates and contract values are made in the period in which the facts giving rise to the revisions become known and can influence the timing of when revenues are recognized under the percentage of completion method of accounting. Such revisions have historically not had a material effect on the amount of revenue recognized. The completed contract method is used for certain contracts that are not long-term in nature or when reasonably dependable estimates of the percentage of completion cannot be made. When the completed contract method is used, revenue and costs are deferred until the contract is substantially complete, which usually occurs upon customer acceptance of the installed product. Provisions are made for estimated losses on uncompleted contracts in the period in which such losses are determined.

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 mathematical 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.

Accounts receivable includes unbilled receivables, representing revenues recognized in excess of billings on uncompleted contracts under the percentage of completion method of accounting.

New Accounting Pronouncements

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments in this Update simplify the income tax effects, minimum statutory tax withholding requirements and impact of forfeitures related to how share-based payments are accounted for and presented in the financial statements. ASU 2016-09 is effective for the Company beginning on January 1, 2017. The adoption of ASU 2016-09 did not have a material effect on our earnings, cash flows, or financial position. See Note 7, Stock-Based Compensation, for further discussion.

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This new accounting guidance more clearly articulates the requirements for the measurement and disclosure of inventory. Topic 330, Inventory, currently requires an entity to measure inventory at the lower of cost or market. Market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. This new accounting guidance requires the measurement of inventory at lower of cost and net realizable value. The adoption of ASU 2015-11 is effective for the Company beginning on January 1, 2017 and the adoption did not have a material impact on the Company’s consolidated financial statements.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09 "Revenue from Contracts with Customers" (Topic 606). This new accounting guidance on revenue recognition provides for a single five-step model to be applied to all revenue contracts with customers. The new standard also requires additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. In August 2015, the FASB approved a one-year deferral to January 1, 2018. Early adoption is permitted as of the original effective date. The standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The amendments in this Update increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 will be effective for the Company beginning on January 1, 2019. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force). The amendments in this Update require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. ASU 2016-18 will be effective for the Company beginning on January 1, 2018. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in this Update simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. ASU 2017-04 will be effective for the Company beginning on January 1, 2020. The Company is in the initial stages of evaluating the impact of the new standard on the accounting policies, processes, and system requirements. While the Company continues to assess the potential impacts of the new standard and anticipate this standard could have a material impact on the consolidated financial statements, the Company does not know or cannot reasonably estimate quantitative information related to the impact of the new standard on the financial statements at this time.
