Note T. Stock-Based Compensation

We measure stock-based compensation expense at the grant date, based on the estimated fair value of the award, and the expense is recognized over the requisite employee service period (generally the vesting period) for awards expected to vest (considering estimated forfeitures).

The Company has an amended and restated long-term incentive plan (the "Plan") that was adopted in conjunction with our initial public offering in 2004. On February 27, 2008, our Board of Directors approved an amendment to our Plan, subject to shareholder approval, that increased the maximum number of shares of common stock available for awards under the Plan from 2,000,000 to 2,175,000 and extended the Plan's termination date. Our shareholders approved this Plan amendment on April 22, 2008, and the Plan now terminates twenty years from the date of such approval, or April 22, 2028. Forfeited and expired options under the Plan become generally available for reissuance. At December 31, 2012, no shares remained available for award under the Plan.

Stock Options and Grants

We use the Black-Scholes option pricing model to estimate the fair value of each option grant as of the date of grant. The volatilities are based on the 90 day historical volatility of our common stock as the grant date. The risk free interest rate is based on zero-coupon U.S. government issues with a remaining term equal to the expected life of the option.

There were no options granted during the years ended December 31, 2012, 2011 and 2010. The Company recognized no stock-based compensation expense related to stock options for the years ended December 31, 2012, 2011 and 2010 as all options previously granted are fully vested. A total of 9,534 options expired in the third quarter of 2010 with a weighted average exercise price of $17.03. The option expirations are due to out-of-the-money options that were not exercised prior to their expiration date. The expired options were returned to the pool of shares generally available for future use under the Long-Term Incentive Plan and subsequently re-issued.

On April 25, 2012, the Company authorized vested stock grants to certain directors totaling 12,995 shares. The total value of the grant, based on the fair value of the stock on the grant date was $245 which was fully expensed at the grant date and is included in general and administrative expenses.

On April 29, 2011, we authorized vested stock grants to certain directors totaling 14,009 shares. The total value of the grant, based on the market value of the underlying common stock at the date of grant was $245, which was fully expensed in the year the award was granted and is included in general and administrative expenses.

On April 28, 2010, we authorized vested stock grants to certain directors totaling 12,892 shares. The total value of the grant was $220 and is included in general and administrative expenses. On September 22, 2010, we authorized vested stock grants to certain directors totaling 1,504 shares. The total value of the grant was $25 and is included in general and administrative expenses.

The Company recognized $245 of stock based compensation expense for each of the years ended December 31, 2012, 2011 and 2010, which is included in general and administrative expense. As of December 31, 2012, there was no unrecognized compensation costs related to unvested options.

Restricted Stock Units

In March 2008, the Company's Board of Directors authorized a one-time grant of 750,000 restricted stock units that subsequently were awarded to members of our senior management team on July 1, 2008. In November 2008, an additional 5,000 restricted stock units were also awarded. The restricted stock units vest in one-third installments on each of the tenth, eleventh and twelfth anniversaries of the grant date. The restricted stock unit agreements are designed to reward performance over a decade or longer.

In October 2012, the Company's Board of Directors authorized a one-time grant of 191,895 restricted stock units that were awarded to our senior management team. The restricted stock units vest in one third installments on each of the first, second and third anniversaries of the Grant Date. The restricted stock unit agreements are designed to reward performance over a three year period. Additionally in October 2012, as part of employment agreements, 30,529 restricted stock units were awarded and shall become vested on the third anniversary of the Grant Date.

The fair value of restricted stock units is determined using the market value of our common stock on the date of the grant, and compensation expense is recognized over the vesting period. In accordance with the guidance related to share-based payments, we estimate forfeitures at the time of the grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. We use historical data to estimate pre-vesting forfeitures and record stock-based compensation expense only for those awards that are expected to vest.

A summary of the status of the restricted stock units as of December 31, 2012, and changes during the year ended December 31, 2012 and 2011, is presented below and there was no activity for the years ended December 31, 2010:
