For the years ended December 31, 2015, 2014 and 2013, options to purchase approximately 2.5 million, 5.6 million and 7.3 million shares, respectively, were excluded from the calculation because they were anti-dilutive after considering proceeds from exercise, taxes and related unrecognized stock-based compensation expense. For the year ended December 31, 2013, an additional 3.3 million potentially dilutive shares have been excluded from the weighted average dilutive shares because there was a net loss for the period. These shares do not include the Company’s 5% convertible senior notes due 2014 (the "2014 Notes") and 1.125% convertible senior notes due 2018 (the "2018 Notes"). The par amount of convertible notes is payable in cash equal to the principal amount of the notes plus any accrued and unpaid interest and then the “in-the-money” conversion benefit feature at the conversion price above $19.31 and $12.07, respectively, per share is payable in cash, shares of the Company’s common stock or a combination of both. Refer to Note 10, "Convertible Notes” for more details.
