13. EQUITY INCENTIVE PLANS
In May 2004, the Company adopted its 2004 Equity Incentive Plan (“2004 Plan”), which replaced its 2000 Omnibus Equity Incentive Plan (“2000 Plan”). The 2000 Plan had allowed for the award of up to 11,500,000 shares of Class A common stock. The 2004 Plan allows for the award of up to 10,000,000 shares of Class A common stock, plus any grants remaining available at its adoption date under the 2000 Plan. Awards under the 2004 Plan may be in the form of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock or restricted stock units. The 2004 Plan is administered by a committee appointed by the Board. This committee determines the type, number, vesting requirements and other features and conditions of such awards. Generally, stock options granted from the 2000 Plan have a contractual term of ten years from the date of the grant and vest over four or five years and stock options granted from the 2004 Plan have a contractual term of ten years from the date of the grant and vest over four years.
The 2004 Plan was amended by the Compensation Committee effective July 13, 2006 to (i) eliminate automatic option grants for non-employee directors, making any grants to such directors discretionary by the Compensation Committee and (ii) eliminate the three-year minimum vesting period for performance-based restricted stock and restricted stock units, making the vesting period for such grants discretionary by the Compensation Committee.
The Company has issued stock options and restricted stock units to various employees and non-employee directors of the Company in addition to non-employee service providers under both the 2004 Plan and the 2000 Plan.
Stock Options
The fair value of each stock option is estimated on the date of grant using the Black-Scholes option pricing model that uses the assumptions noted in the following table. Stock-based compensation expense related to stock options is based on the fair value on the date of grant and is amortized over the vesting period, generally between 1 to 3 years. Expected volatilities are based on historical volatility of the Company’s stock. The Company uses historical data to estimate option exercise and employee termination within the valuation model. The expected term of stock options granted is based on historical contractual life and the vesting data of the stock options. The risk-free rate for periods within the contractual life of the stock option is based on the U.S. Treasury yield curve in effect at the time of grant.
The fair value of each stock option granted was estimated using the following weighted-average assumptions:
