There were no adjustments to net income required for purposes of computing diluted earnings per share.

Share options, appreciation rights and restricted share units granted under share-based compensation plans are antidilutive and excluded from diluted earnings per share when the hypothetical number of shares that could be repurchased under the treasury stock method exceeds the number of shares to be exercised. Antidilutive shares, which could potentially dilute earnings per share in the future, are set forth below (in thousands):



	Three months ended June 30,		Six months ended June 30,
