Note 7 - Stock-Based Compensation | 12 Months Ended
--- | ---
Dec. 31, 2012
Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | 7. STOCK-BASED COMPENSATION Fuel Tech has a stock-based employee compensation plan, referred to as the Fuel Tech, Inc. Incentive Plan (Incentive Plan), under which 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 Fuel Tech’s directors, officers, employees, consultants or advisors (except consultants or advisors in capital-raising transactions) as the directors determine are key to the success of Fuel Tech’s business. The amount of shares that may be issued or reserved for awards to participants under a 2004 amendment to the Incentive Plan is 12.5% of outstanding shares calculated on a diluted basis. At December 31, 2012, Fuel Tech had approximately 430,000 equity awards available for issuance under the Incentive Plan 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 years ended December 31, 2012, 2011, and 2010 were as follows:
|  | For the Year Ended December 31, |
|  | 2012 |  |  | 2011 |  |  | 2010 |
Stock options |  | $ | (66) |  |  | $ | 2,077 |  |  | $ | 4,170 |
Restricted stock units |  |  | 1,314 |  |  |  | 672 |  |  |  | 9 |
Deferred directors fees |  |  | 58 |  |  |  | 61 |  |  |  | 95 |
Total stock-based compensation expense |  |  | 1,306 |  |  |  | 2,810 |  |  |  | 4,274 |
Tax benefit of stock-based compensation expense |  |  | (472) |  |  |  | (959) |  |  |  | (1,412) |
After-tax effect of stock based compensation |  | $ | 834 |  |  | $ | 1,851 |  |  | $ | 2,862 |
As of December 31, 2012, there was $2,265 of total unrecognized compensation cost related to all non-vested share-based compensation arrangements granted under the Incentive Plan. That cost is expected to be recognized over the requisite service period of two years. Stock Option Exchange Program On June 1, 2011, the Company commenced an exchange program that offered to certain employees the right to exchange eligible options to purchase shares of common stock of the Company for a lesser number of replacement awards of restricted stock units. The exchange offer expired on June 29, 2011. Pursuant to the exchange offer, 814,500 eligible options were tendered by 97 employees and the Company granted 267,372 restricted stock units in exchange for those options. As a result of the exchange, which is deemed a modification of the original stock option awards under generally accepted accounting principles, additional stock-based compensation of approximately $252 will be recognized over the two year vesting period associated with the replacement awards commencing June 30, 2011. The additional stock compensation was determined by comparing the fair value of the options tendered immediately prior to the exchange to the intrinsic value of the RSUs granted immediately after the exchange. The fair value of the options was calculated using the Black-Scholes option pricing model. The Company recognized $126 and $63 of additional stock-based compensation during the years ended December 31, 2012 and 2011, respectively, as a result of the stock option exchange program, which is included in the stock compensation related to RSUs in the table above. Additional information regarding the stock option exchange program may be found on the Company’s Tender Offer Statement on Schedule TO filed with the SEC on June 1, 2011. Stock Options The stock options granted to employees under the Incentive Plan 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. Based on the results of the model, the weighted-average fair value of the stock options granted during the 12-month periods ended December 31, 2012, 2011, and 2010, respectively, were $1.72, $4.08, and $3.38 per share using the following weighted average assumptions:
|  | 2012 |  | 2011 |  | 2010
Expected dividend yield |  |  | 0.00 | % |  |  | 0.00 | % |  |  | 0.00 | %
Risk-free interest rate |  |  | 0.67 | % |  |  | 1.80 | % |  |  | 1.74 | %
Expected volatility |  |  | 58.6 | % |  |  | 57.2 | % |  |  | 67.7 | %
Expected life of option (years) |  |  | 4.8 |  |  |  | 5.0 |  |  |  | 5.5 |

As of December 31, 2012, there was $235 of total unrecognized compensation cost related to non-vested stock options granted under the Incentive Plan. That cost is expected to be recognized over a weighted average period of 0.7 years. Fuel Tech received proceeds from the exercise of stock options of $ 0, $376, and $10 in the years ended December 31, 2012, 2011, and 2010, respectively. The intrinsic value of options exercised in the years ended December 31, 2012, 2011, and 2010 was $ 0, $256, and $2, respectively. It is our policy to issue new shares upon option exercises, loan conversions, and vesting of restricted stock units. We have not used cash and do not anticipate any future use of cash to settle equity instruments granted under share-based payment arrangements. 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 Company’s common stock 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, in March 2011 and 2012, the Company entered into performance-based RSU agreements (the Agreements) with each of the Company’s President/Chief Executive Officer, Treasurer/Chief Financial Officer, Executive Vice President of Marketing & Sales, and Executive Vice President of Worldwide Operations. 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 the Company’s 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 intrinsic value method 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 intrinsic value method 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.
The Company recorded expense of approximately $1,314, $672 and $9 associated with its restricted stock unit awards in 2012, 2011 and 2010, respectively, and at December 31, 2012 there is $2,030 of unrecognized compensation costs related to restricted stock unit awards to be recognized over a weighted average period of 2.09 years. During the year ended December 31, 2012, there were 72,250 restricted stock units that vested with a fair value of $307. There were no restricted stock units that vested during the year ended December 31, 2011. A summary of restricted stock unit activity for the year ended December 31, 2012 and 2011 is as follows:
|  | Shares |  |  | Weighted Average Grant Date Fair Value |

Deferred Directors Fees In addition to the Incentive Plan, Fuel Tech has a Deferred Compensation Plan for Directors (Deferred Plan). Under the terms of the Deferred Plan, Directors can elect to defer Directors’ fees for shares of Fuel Tech Common Stock that are issuable at a future date as defined in the agreement. In accordance with ASC 718, Fuel Tech accounts for these awards as equity awards as opposed to liability awards. In 2012, 2011, and 2010, Fuel Tech recorded $58, $61, and $95, respectively, of stock-based compensation expense under the Deferred Plan.
