[2] In calculating diluted net income per share, 1.3 million shares and 78 thousand shares related to outstanding stock options and unvested, undelivered restricted stock units were excluded for the three months ended March 31, 2023 and 2022, respectively. Additionally, for the three months ended March 31, 2023, the interest expense and amortization of note costs relating to the shares issuable upon conversion of our outstanding convertible notes were excluded from the calculation as they would have been anti-dilutive. For the three months ended March 31, 2022, in calculating diluted net income per share, we excluded the impact of interest expense and amortization of note costs relating to the shares issuable upon conversion of our outstanding convertible notes from net income and included the weighted average shares under the if-converted method. For each of the three months ended March 31, 2023, and 2022 interest expense including amortization of note issuance costs, related to convertible notes was $0.6 million. For each of the three months ended March 31, 2023, and 2022 the weighted average shares under the if-converted method for our convertible bond was 3.9 million shares.
