STOCK-BASED COMPENSATION
STOCK-BASED COMPENSATION
Stock-based compensation for the three months ended August 31, 2014 and 2013 was $8.6 million and $7.9 million, respectively. Stock-based compensation for the nine months ended August 31, 2014 and 2013 was $31.9 million and $39.2 million, respectively. The deferred tax benefit from stock-based compensation for the three months ended August 31, 2014 and 2013 was $2.4 million and $1.9 million, respectively. The deferred tax benefit from stock-based compensation expenses for the nine months ended August 31, 2014 and 2013 was $8.9 million and $11.3 million, respectively.

Since fiscal year 2010, certain of our employees received performance-based restricted stock units ("PRSUs"). These PRSUs are subject to the terms and conditions set forth in each applicable PRSU Agreement and have been granted under our 2008 Equity Incentive Plan. In February and May of 2014, we granted 1.7 million PRSUs to certain senior executives with performance-based and time-based vesting requirements. On August 1, 2014, we cancelled the previously granted shares and granted 0.9 million PRSUs with new market-based and time-based vesting requirements. During the nine months ended August 31, 2014, a total of 2.6 million PRSUs were granted and 1.8 million shares vested.

The following table summarizes additional information pertaining to our stock-based compensation from stock options and stock awards, which are comprised of restricted stock, restricted stock units and performance-based restricted stock units (in thousands, except grant-date fair value and recognition period):
