[1]	As the average price of our common stock was below $31.47 per share since the issuance date of the 2.75% Convertible Notes, the number of shares used in calculating diluted net income (loss) per share for the three and nine months ended September 30, 2020 excluded the potential dilution from the 2.75% Convertible Notes converting into shares of common stock.
[2]	Due to the net losses, RSUs representing approximately 636,000, 580,000 and 393,000 for the three and nine months ended September 30, 2020 and nine months ended September 30, 2019, respectively, have been excluded from the number of shares used in calculating diluted net loss per share, as their inclusion would be antidilutive.
