Earnings per Share Data

Basic earnings per share excludes the dilutive effects of stock options, restricted stock units (RSUs), and the nil coupon non-redeemable convertible unsecured loan notes. Diluted earnings per share includes the dilutive effect of stock options, restricted stock units, and of the nil coupon non-redeemable convertible unsecured loan notes. The following table sets forth the weighted-average shares used in calculating the earnings per share for the three-month periods ended June 30, 2013 and 2012.
