Our stock-based compensation program (the “Stock Plan”) provides for the grant of stock appreciation rights, performance stock units, restricted stock units, restricted stock awards, and performance stock awards (collectively, “Stock Awards”), stock options, or any other stock-based award. As of September 30, 2022, approximately 16 million shares of our common stock were available for subsequent issuance under the Stock Plan. For a full description of our stock-based compensation program refer to Note 17 of our 2021 Annual Report on Form 10-K.
