2. Net Income Per Share

Basic net income per share attributable to Innoviva stockholders is computed by dividing net income attributable to Innoviva stockholders by the weighted-average number of shares of common stock outstanding. Diluted net income per share attributable to Innoviva stockholders is computed by dividing net income attributable to Innoviva stockholders by the weighted-average number of shares of common stock and dilutive potential common stock equivalents then outstanding. Dilutive potential common stock equivalents include the assumed exercise, vesting and issuance of employee stock awards using the treasury stock method, as well as common stock issuable upon assumed conversion of our convertible subordinated notes due 2023 (the “2023 Notes”), our convertible senior notes due 2025 (the “2025 Notes”) and our convertible senior notes due 2028 (the “2028 Notes”) using the if-converted method.

Our convertible senior notes due 2025 (the “2025 Notes”) are convertible, based on the applicable conversion rate, into cash, shares of our common stock or a combination thereof, at our election. Our current intent is to settle the principal amount of the 2025 Notes in cash upon conversion. The impact of the assumed conversion premium to diluted net income per share was historically computed using the treasury stock method. As the average market price per share of our common stock as reported on The Nasdaq Global Select Market was lower than the initial conversion price of $17.26 per share, there was no dilutive effect of the assumed conversion premium for the three and six months ended June 30, 2021. The dilutive EPS of the notes was approximately $0.01 and $0.03 per share, respectively, using the if-converted method for the three and six months ended June 30, 2022 as a result of the adoption of ASU 2020-06.
