STOCK-BASEDCOMPENSATION

We account for stock options and restricted stock issued under our long term incentive plans in accordance with ASC 718, Compensation – Stock Compensation. The fair value of stock-based compensation is determined at the grant date. The related compensation expense is recognized over the appropriate vesting period. See Note 7 of the Notes to the Consolidated Financial Statements for additional information.

We determined the fair value of stock options and restricted stock issued under our long term incentive plans as of the grant date. The fair value of restricted stock was determined by the closing market price of our Common Stock on the date of grant multiplied by the number of shares granted. The fair value of the stock options was estimated on the date of the grant using a Black-Scholes option valuation model that used various assumptions. The risk free interest rate was based on the U.S. Treasury yield curve in effect at the time of grant. Expected life (estimated period of time outstanding) of a grant was determined by reference to the vesting schedule and past exercise behavior. The dividend rate at the date of grant was used as the best estimate of future dividends. Expected volatility was determined by calculating the standard deviation of our stock price for the five years immediately prior to the grant date. This period of time closely resembles the expected term. All stock options issued under our plans have an exercise price equal to the closing market price of our Common Stock on the date of grant.
