For the years ended December 31, 2020, 2019 and 2018, options to purchase approximately 0.3 million, 1.0 million and 1.6 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 years ended December 31, 2020, 2019 and 2018, an additional 2.3 million, 2.4 million and 2.4 million shares, respectively, have been excluded from the weighted-average dilutive shares because there was a net loss for the periods. These shares do not include the Company’s 2023 Notes and the 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 $18.93 and $12.07, respectively, per share is payable in cash, shares of the Company’s common stock or a combination of both. The Company has the option to pay cash, issue shares of common stock or any combination thereof for the aggregate amount due upon conversion of the notes. The Company’s intent is to settle the principal amount of the notes in cash upon conversion. As a result, upon conversion of the notes, only the amounts payable in excess of the principal amounts of the notes are considered in diluted earnings per share under the treasury stock method. Refer to Note 12, “Convertible Notes” for more details.
