Earnings Per Share Reconciliation [Abstract]

Net Income (Loss) Per Share

(16)  NET INCOME (LOSS) PER SHARE

The following table summarizes the computations of basic earnings per share (“Basic EPS”) and diluted earnings per share (“Diluted EPS”). Basic EPS is computed as net income (loss) divided by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur from common shares issuable through stock-based compensation plans including stock options, restricted stock, restricted stock units, common stock through our ESPP, warrants, and other convertible securities using the treasury stock method.

Net income (loss) per share:

Diluted	$	0.31	$	0.23	$	(0.84	)

As a result of our net loss for the fiscal year ended March 31, 2011, we have excluded all outstanding equity-based instruments from the diluted loss per share (“Diluted EPS”) calculation as their inclusion would have had an antidilutive effect. Had we reported net income for the period, an additional 4 million shares of common stock would have been included in the number of shares used to calculate Diluted EPS.

Potentially dilutive shares of common stock related to our 0.75% Convertible Senior Notes due 2016 issued during the year ended March 31, 2012, which have a conversion price of $31.74 per share and the associated Warrants, which have a conversion price of $41.14 per share, were excluded from the computation of Diluted EPS for the year ended March 31, 2013 and 2012 as their inclusion would have had an antidilutive effect resulting from the conversion price. The associated Convertible Note Hedge was excluded from the calculation of diluted shares as the impact is always considered antidilutive since the call option would be exercised by us when the exercise price is lower than the market price. See Note 11 for additional information related to our 0.75% Convertible Senior Notes due 2016 and related Convertible Note Hedge and Warrants.
