The Company utilizes the Monte Carlo simulation valuation model to value market-based restricted stock units. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the performance conditions stipulated in the award grant and calculates the fair market value for the market-based restricted stock units granted. The Monte Carlo simulation model also uses stock price volatility and other variables to estimate the probability of satisfying the performance conditions, including the possibility that the market condition may not be satisfied, and the resulting fair value of the award. Market-based restricted stock units were not granted during the three-month periods ended January 31, 2015 or February 1, 2014.

In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the future. The number of options expected to vest is calculated by applying an estimated forfeiture rate to the unvested options.
