Certain key employees have been granted time-based, performance-based and market-based restricted stock awards. The time-based restricted awards granted generally vest on a graded vesting schedule over three years. The performance-based restricted awards generally vest on a cliff vesting schedule over three to five years and provide a range of vesting possibilities of up to a maximum of 100% or 150%, depending on the specified performance condition and the level of achievement obtained. The market-based awards have a vesting condition that is tied to the Company’s stock performance in relation to the Standard and Poor’s (S&P) Super Composite Technology Hardware and Equipment Index. The market conditions are considered in the grant date fair value using a Monte Carlo valuation model, which utilizes multiple input variables to determine the probability of the Company achieving the specified market conditions. Stock-based compensation expense related to an award with a market condition will be recognized over the requisite service period regardless of whether the market condition is satisfied, provided that the requisite service period has been completed. During the nine months ended May 31, 2016 and 2015, the Company awarded approximately 2.6 million and 2.8 million time-based restricted stock units, respectively, 1.3 million and 1.7 million performance-based restricted stock units, respectively and 0.4 million and 0.0 million market-based stock units, respectively.

At May 31, 2016, there was $76.9 million of total unrecognized stock-based compensation expense related to restricted stock awards. This expense is expected to be recognized over a weighted-average period of 1.5 years.
