[1]	On April 27, 2023, the Company’s stockholders approved these additional shares to be reserved for issuance under the 2015 Equity Incentive Plan (the “2015 Plan”).
[2]	Amount includes approximately 0.2 million shares that have been reserved for potential future issuance related to certain performance unit awards granted in the first quarter of 2023 and discussed under the section titled “Nonvested Equity Stock and Stock Units” below.
[3]	For purposes of determining the number of shares available for grant under the 2015 Plan against the maximum number of shares authorized, each restricted stock unit granted prior to April 27, 2023 reduces the number of shares available for grant by 1.5 shares and each restricted stock unit forfeited increases shares available for grant by 1.5 shares. Each restricted stock unit granted on or after April 27, 2023 reduces the number of shares available for grant by 1.0 shares and each restricted stock unit forfeited increases shares available for grant by 1.0 shares.
