- Definition Aggregate awards of nonvested shares to be issued to employees under a share-based compensation arrangement are considered restricted unit awards for purposes of computing diluted earnings per share. Such share-based awards shall be considered to be outstanding as of the grant date for purposes of computing diluted earnings per share even though their release may be contingent upon vesting. Those share-based awards are included in the diluted Earnings Per Share (EPS) computation even if the employees may not receive (or be able to sell) the stock until some future date. Accordingly, all shares to be issued shall be included in computing diluted EPS if the effect is dilutive. The dilutive effect of share-based compensation arrangements shall be computed using the treasury stock method. If the equity share options or other equity instruments are outstanding for only part of a period, the shares issuable shall be weighted to reflect the portion of the period during which the equity instruments were outstanding. + References No definition available. + Details
