(6)       Share-Based Compensation

Our Amended and Restated 1986 Stock Option Plan ("Stock Option Plan"), provides for the grant of options and restricted stock awards (collectively "award") for a maximum of 15.7 million shares of GCI Class A common stock, subject to adjustment upon the occurrence of stock dividends, stock splits, mergers, consolidations or certain other changes in corporate structure or capitalization. If an award expires or terminates, the shares subject to the award will be available for further grants of awards under the Stock Option Plan. The Compensation Committee of GCI's Board of Directors administers the Stock Option Plan. Substantially all restricted stock awards granted vest over periods of up to three years. Substantially all options vest in equal installments over a period of five years and expire ten years from the date of grant. The requisite service period of our awards is generally the same as the vesting period. Options granted pursuant to the Stock Option Plan are only exercisable if at the time of exercise the option holder is our employee, non-employee director, or a consultant or advisor working on our behalf. New shares of GCI Class A common stock are issued when stock option agreements are exercised or restricted stock awards are granted.

The fair value of restricted stock awards is determined based on the number of shares granted and the quoted price of our common stock. We use a Black-Scholes-Merton option pricing model to estimate the fair value of stock options issued. The Black-Scholes-Merton option pricing model incorporates various and highly subjective assumptions, including expected term and expected volatility. We have reviewed our historical pattern of option exercises and have determined that meaningful differences in option exercise activity existed among employee job categories. Therefore, we have categorized these awards into two groups of employees for valuation purposes.

The weighted average grant date fair value of options granted during the six months ended June 30, 2010 was $2.84 per share. There were no options granted during the six months ended June 30, 2011. The total fair value of options vesting during the six months ended June 30, 2011 and 2010 was $97,000 and $82,000, respectively.

The following is a summary of our share-based compensation expense for the six months ended June 30, 2011 and 2010 (in thousands):

Share-based compensation expense is classified as selling, general and administrative expense in our Consolidated Statement of Operations. Unrecognized share-based compensation expense was $6.4 million relating to 2.5 million restricted stock awards and $490,000 relating to 308,000 unvested stock options as of June 30, 2011. We expect to recognize share-based compensation expense over a weighted average period of 1.3 years for stock options and restricted stock awards.

In January 2001 we entered into an aircraft operating lease agreement with a company owned by our President and Chief Executive Officer. The lease was amended several times, most recently on May 9, 2011. Upon signing the lease in January 2001, the lessor was granted an option to purchase 250,000 shares of GCI Class A common stock at $6.50 per share, of which 100,000 shares were exercised during the year ended December 31, 2006 and the remaining 150,000 shares expired on March 31, 2010.
