The fair value of restricted stock awards is based on the price of the stock in the open market on the date of the grant, and the fair value of performance-based restricted stock units is determined by using the Monte Carlo valuation model. The fair value of the restricted stock awards is recorded as compensation expense on a straight-line basis over the vesting periods of the awards and we account for forfeitures when they occur.
