Common stock of approximately 0.1 million and 0.5 million shares at June 30, 2021, and 2020, respectively that are issuable through exercise of dilutive securities were not included in the computation of diluted net income per share because their effect would have been anti-dilutive.

Performance Shares and Restricted Units that entitle the holders to approximately 0.5 million shares of common stock are included in the basic and diluted weighted average shares outstanding calculation from their date of issuance because no further consideration is due related to the issuance of the underlying common shares.

Based on the adoption of ASU 2020-06, as the principal amount of the 2025 Notes will be paid in cash and only the conversion spread is settled in shares, the Company will be utilizing the if-converted method and only includes the net number of incremental shares that would be issued upon conversion.
