Earnings Per Share

Basic earnings per share is calculated by dividing net earnings attributable to Encore by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is calculated on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding stock options, restricted stock, warrants, and the dilutive effect of the convertible senior notes.

A reconciliation of shares used in calculating earnings per basic and diluted shares follows (in thousands):



	Three Months Ended March 31,
	2014	2013
Weighted average common shares outstanding—basic	25,749	23,446
Dilutive effect of stock-based awards	906	968
Dilutive effect of convertible senior notes	1,461	—
Dilutive effect of warrants	80	—
Weighted average common shares outstanding—diluted	28,196	24,414

No anti-dilutive employee stock options were outstanding during the three months ended March 31, 2014 or 2013.

The Company has the following convertible senior notes outstanding: $115.0 million convertible senior notes due 2017 at a conversion price equivalent to approximately $31.56 per share of the Company’s common stock (the “2017 Convertible Notes”), $172.5 million convertible senior notes due 2020 at a conversion price equivalent to approximately $45.72 per share of the Company’s common stock (the “2020 Convertible Notes”), and $161.0 million convertible senior notes due 2021 at a conversion price equivalent to approximately $59.39 per share of the Company’s common stock (the “2021 Convertible Notes”).

In the event of conversion, the 2017 Convertible Notes are convertible into cash up to the aggregate principal amount and permit the excess conversion premium to be settled in cash or shares of Company’s common stock. For the 2020 Convertible Notes and 2021 Convertible Notes, the Company has the option to pay cash, issue shares of common stock or any combination thereof for the aggregate amount due upon conversion. The Company’s intent is to settle the principal amount of the 2020 and 2021 Convertible Notes in cash upon conversion. As a result, upon conversion of all the convertible senior notes, only the amounts payable in excess of the principal amounts are considered in diluted earnings per share under the treasury stock method. For the three months ended March 31, 2014, diluted earnings per share includes the effect of the common shares issuable upon conversion of the 2017 Convertible Notes and the 2020 Convertible Notes because the average stock price exceeded the conversion price of these notes. However, as described in Note 9 “Debt—Encore Convertible Senior Notes,” the Company entered into certain hedge transactions that have the effect of increasing the effective conversion price of the 2017 Convertible Notes to $60.00 and the 2020 Convertible Notes to $61.55. For the three months ended March 31, 2013, the average stock price was below the initial conversion price of the Company’s outstanding convertible senior notes and thus the impact of an assumed conversion was not applicable. On January 2, 2014, the 2017 Convertible Notes became convertible as certain conditions for conversion were met in the immediately preceding calendar quarter as defined in the applicable indenture. However, none of the 2017 Convertible Notes were converted during the three months ended March 31, 2014.

In conjunction with the issuance of the 2017 Convertible Notes, the Company entered into privately negotiated transactions with certain counterparties and sold warrants to purchase approximately 3.6 million shares of its common stock. The warrants had an exercise price of $44.19. On December 16, 2013, the Company entered into amendments with the same counterparties to exchange the original warrants with new warrants with an exercise price of $60.00. All other terms and settlement provisions remain unchanged. The warrant restrike transaction was completed on February 6, 2014. Diluted earnings per share includes the effect of these warrants for the three months ended March 31, 2014. The effect of the warrants was anti-dilutive for the three months ended March 31, 2013. Refer to Note 9 “Debt—Encore Convertible Senior Notes—2017 Convertible Senior Notes” for further details of the warrant restrike transaction.
