In fiscal year 2010, we granted 4.1 million PRSUs that contain performance metrics based on the attainment and maintenance of specified non-GAAP EPS goals. If the performance criteria are achieved, these PRSUs will be considered outstanding for the purpose of computing diluted EPS if the effect is dilutive. Please see Note 11 for additional details. The dilutive impact of these awards will be deferred until the first quarter of fiscal year 2013, at the earliest, when and if the performance criteria of the awards have been met.

Additionally, we granted 0.3 million of PRSUs in the first quarter of fiscal year 2011 that are not included in the diluted net income per share calculation. The dilutive impact of these awards will be deferred until the first quarter of fiscal year 2012 when and if the performance criteria of the awards have been met.
