Weighted average options to purchase approximately 8,000 shares of the Company’s common stock, par value $0.01 per share (“Common Stock”), were outstanding during the three and six months ended June 30, 2017, but were not included in the computation of diluted shares as the effect would be anti-dilutive. There were no options outstanding as of June 30, 2018. Weighted average restricted stock awards of 99,000 and 29,000 were outstanding during the three and six months ended June 30, 2018, respectively, but were not included in the computation of diluted shares as the effect would be anti-dilutive or performance targets were not expected to be achieved for awards contingent upon performance. Weighted average restricted stock awards of 47,000 and 90,000 were outstanding during the three and six months ended June 30, 2017, respectively, but were not included in the computation of diluted shares as the effect would be anti-dilutive or performance targets were not expected to be achieved for awards contingent upon performance. ASC 260, “Earnings per Share,” requires that employee stock options and non-vested restricted shares granted by the Company be treated as potential common shares outstanding in computing diluted earnings per share. Under the treasury stock method, the amount the employee must pay for exercising stock options and the amount of compensation cost for future services that the Company has not yet recognized are assumed to be used to repurchase shares.
