[1] [1] To hedge against potential dilution upon conversion of the 2017 Convertible Notes, the Company purchased call options on its common stock from the hedge counter-parties. The call options give the Company the right to purchase up to 20.8 million shares of its common stock at $28.86 per share. These call options are not considered for purposes of calculating the total shares outstanding under the basic and diluted net income per share, as their effect would be anti-dilutive. Upon exercise, the call options would serve to neutralize the dilutive effect of the 2017 Convertible Notes and potentially reduce the weighted number of diluted shares used in per share calculations.
