Unvested restricted shares have voting rights and receive nonforfeitable dividends during the vesting period; therefore, they are included in calculating basic earnings per share. The portion of unvested performance-based restricted stock units that are expected to vest, but have not yet been awarded, are included in the calculation of diluted earnings per share.
