In accordance with the Earnings Per Share Topic of the FASB ASC, basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period (excluding nonvested restricted stock). Diluted earnings per share is determined based on the dilutive effect of unvested restricted stock probable of vesting using the treasury stock method. During the years ended December 31, 2013, 2012 and 2011, there were no anti-dilutive shares of common stock excluded from the computation of diluted earnings per share. The weighted average number of repurchased shares during the period that are held as treasury stock are excluded from common stock outstanding.
