Shared-Based Compensation

GCI's 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 are issued when stock option agreements are exercised or restricted stock awards are granted.  We have 3.9 million shares available for grant under the Stock Option Plan at June30, 2012.

 

The fair value of restricted stock awards is determined based on the number of shares granted and the quoted price of GCI's Class A 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.

 

We estimated the expected term of options granted by evaluating the vesting period of stock options, employee's past exercise and post-vesting employment departure behavior, and expected volatility of the price of the underlying shares.

 

We estimated the expected volatility of our common stock at the grant date using the historical volatility of our common stock over the most recent period equal to the expected stock option term and evaluated the extent to which available information indicated that future volatility may differ from historical volatility.

 

The risk-free interest rate assumption was determined using the Federal Reserve nominal rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. We have never paid any cash dividends on our common stock and we do not anticipate paying any cash dividends in the foreseeable future. Therefore, we assumed an expected dividend yield of zero.

We estimate pre-vesting option forfeitures at the time of grant and periodically revise those estimates in subsequent periods if actual forfeitures differ from those estimates. We record share-based compensation expense only for those awards expected to vest using an estimated forfeiture rate based on our historical pre-vesting forfeiture data.  We review our forfeiture estimates annually and adjust our share-based compensation expense in the period our estimate changes.
