COMPUTATION OF EARNINGS PER COMMON SHARE

Basic and diluted earnings per share are computed using the two-class method. The two-class method is an earnings allocation formula that determines net income per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Per share amounts are computed by dividing net income attributable to common shareholders by the weighted average shares outstanding during each period.

The Company has a share-based compensation plan under which employees, non-employee directors, and consultants may be granted share-based awards, including shares of restricted stock on which non-forfeitable dividends are paid on unvested shares. As such, shares of restricted stock are considered participating securities under the two-class method of calculating earnings per share. Prior to the second quarter of Fiscal Year 2018, the impact of the two-class method was not considered material and therefore, earnings per share was reported as calculated under the treasury stock method. Had the Company reported earnings per share under the two-class method, basic and diluted earnings per share would have been $0.56 and $0.55, respectively, for the three months ended June 30, 2017 instead of the reported amounts of $0.58 and $0.57, respectively.

The following table sets forth the computation of basic and diluted earnings per common share for the three months ended June 30, 2017 and 2018:
