Earnings Per Share [Abstract]

EARNINGS PER SHARE

EARNINGS PER SHARE

Basic earnings per share is calculated by dividing income available to stockholders by the weighted-average number of common shares outstanding during each period. Diluted earnings per share is computed using the weighted-average number of common and dilutive common share equivalents outstanding during the period. Dilutive common share equivalents consist of shares issuable upon the exercise or settlement of stock awards (calculated using the treasury stock method) during the period they were outstanding.

The following table sets forth the computation of basic and diluted net income per share (in thousands, except per share information):

The weighted-average number of shares outstanding used in the computation of basic and diluted earnings per share does not include the effect of the potential outstanding common stock from the Company's convertible senior notes and warrants. The effects of these potentially outstanding shares were not included in the calculation of diluted earnings per share because the effect would have been anti-dilutive.

The Company uses the treasury stock method for calculating any potential dilutive effect of the conversion spread on its Convertible Senior Notes (the "Convertible Notes") on diluted earnings per share, if applicable, as upon conversion, the Company will pay cash up to the aggregate principal amount of the Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock, at the Company’s election, in respect of the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted. The conversion spread will have a dilutive impact on diluted earnings per share when the average market price of the Company’s common shares for a given period exceeds the conversion price of $90.00 per share. For the three and nine months ended September 30, 2014, the Convertible Notes have been excluded from the computation of diluted earnings per share as the effect would be anti-dilutive since the conversion price of the Convertible Notes exceeded the average market price of the Company’s common stock. In addition, the Company uses the treasury stock method for calculating any potential dilutive effect related to the warrants. See Note 10 to the Company's condensed consolidated financial statements for detailed information on the Convertible Notes offering.
