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 nine months ended September 30, 2014 and 2013.

As discussed in Note 9, “Long-Term Debt”, the Company was required to include the dilutive effect, if applicable, of the net shares issuable under the 2.25% Notes (as defined in Note 9) and the warrants sold in connection with the 2.25% Notes (“2.25% 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 three months ended September 30, 2013 and for the period prior to the conversion and redemption of the 2.25% Notes during the three months ended September 30, 2014, was more than the conversion price then in effect at the end of those periods. Therefore, the respective dilutive effect of the 2.25% Notes was included in the computation of diluted EPS for the three and nine month periods ended September 30, 2014 and 2013. The 2.25% Notes and 2.25% Warrants were converted or redeemed and settled, respectively, during the three months ended September 30, 2014. As a result, the dilution is calculated based on the weighted average length of time the 2.25% Notes and 2.25% Warrants were outstanding during the three and nine months ended September 30, 2014. Refer to Note 9, "Long-Term Debt" for a description of the conversion of the 2.25% Notes and 2.25% Warrants that occurred during the three months ended September 30, 2014. In addition, the Company was required to include the dilutive effect, if applicable, of the net shares issuable under the 3.00% Notes (as defined in Note 9, "Long-Term Debt" ) 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 three months ended September 30, 2013 and for the period prior to the repurchase of the 3.00% Notes during the three months ended September 30, 2014, was more than the conversion price then in effect at the end of those periods. Therefore, the respective dilutive effect of the 3.00% Notes and 3.00% Warrants was included in the computation of diluted EPS for the three and nine months ended September 30, 2014 and 2013. On June 25, 2014, the Company repurchased $92.5 million of the $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. As a result, the dilution is calculated based on the weighted average length of time the 3.00% Notes and 3.00% Warrants were outstanding during the three and nine months ended September 30, 2014. Refer to Note 9, "Long-Term Debt" for a description of the repurchase of the 3.00% Notes and 3.00% Warrants that occurred during the three months ended September 30, 2014.
