The following table presents net income, the weighted average common shares used in calculating basic EPS and those used in calculating diluted EPS for each period presented below. Diluted EPS reflects the incremental common shares from: (1) common shares issuable upon vesting of performance share units (“PSUs”) and the purchase of shares under the Employee Stock Purchase Plan (the “ESPP”) using the treasury stock method; and (2) common shares issuable upon the conversion of the MCPS using the if-converted method. The outstanding restricted stock units (“RSUs”) have non-forfeitable rights to dividend equivalents and are therefore included in calculating basic and diluted EPS under the two-class method.
