Earnings Per Share [Abstract] |
EARNINGS PER SHARE | EARNINGS PER SHARE The two-class method is utilized for the computation of the Company's earnings per share (“EPS”). The two-class method requires a portion of net income to be allocated to participating securities, which are unvested awards of share-based payments with non-forfeitable rights to receive dividends or dividend equivalents, including the Company’s restricted stock awards. Income allocated to these participating securities is excluded from net earnings available to common shares, as shown in the table below. Basic EPS is computed by dividing net income available to basic common shares by the weighted average number of basic common shares outstanding during the period. Diluted EPS is computed by dividing net income available to diluted common shares by the weighted average number of dilutive common shares outstanding during the period. The following table sets forth the calculation of EPS for the three and six months ended June 30, 2015 and 2014.

For the periods during which the Company's 2.25% Convertible Senior Notes due 2036 ("2.25% Notes") were outstanding, the Company was required to include the dilutive effect, if applicable, of the net shares issuable under the 2.25% Notes and the warrants sold in connection with the 2.25% Notes (“2.25% Warrants”) in its diluted common shares outstanding for the diluted earnings per common share calculation. The average adjusted closing price of the Company's common stock for the six months ended June 30, 2014 was more than the conversion price then in effect at the end of the period. Therefore, the dilutive effect of the 2.25% Notes was included in the computation of diluted EPS for the six month period ended June 30, 2014. The 2.25% Notes and 2.25% Warrants were converted or redeemed and settled, respectively, during the three months ended September 30, 2014. In addition, for the periods during which the Company's 3.00% Convertible Senior Notes due 2020 ("3.00% Notes") were outstanding, the Company was required to include the dilutive effect, if applicable, of the net shares issuable under the 3.00% Notes and the warrants sold in connection with the 3.00% Notes (“3.00% Warrants”) in its diluted common shares outstanding for the diluted earnings calculation. The average adjusted closing price of the Company's common stock for the six months ended June 30, 2014 was more than the conversion price then in effect at the end of the period. Therefore, the respective dilutive effect of the 3.00% Notes and 3.00% Warrants was included in the computation of diluted EPS for the six months ended June 30, 2014. On June 25, 2014, the Company repurchased $92.5 million of the then outstanding $115.0 million principal. The remaining 3.00% Notes and 3.00% Warrants were repurchased and settled, respectively, during the three months ended September 30, 2014.
