Basic earnings per share is calculated by the sum of (1) net earnings less declared dividends and dividend equivalents related to share-based compensation divided by the basic weighted average shares outstanding and (2) declared dividends and dividend equivalents related to share-based compensation divided by the weighted average shares outstanding.

The weighted average number of shares outstanding included in the following table were excluded from the computation of diluted earnings per share because the average market price did not exceed the exercise/threshold price. However, these shares may be dilutive potential common shares in the future.
