Share Repurchases Share Repurchases
In June 2021, the Board authorized an anti-dilutive share repurchase program of up to $250 (June 2021 program) to offset the impact of dilution from shares issued under our stock compensation programs. The June 2021 program has no expiration date, but it may be suspended or discontinued at any time. Repurchases under the June 2021 program may be made in open-market or privately negotiated transactions.
In September 2021, the Board approved a new strategic share repurchase program of up to $500 (September 2021 program). The September 2021 program has no expiration date, but it may be suspended or discontinued at any time. Repurchases under the September 2021 program may be made in open-market or privately negotiated transactions. The September 2021 program replaced the prior $1,500 program, which our Board approved in March 2017 and has been cancelled.
During the three-month period ended October 31, 2021, we repurchased approximately 1.5 million shares at a cost of $63. Of this amount, $38 was used to repurchase shares pursuant to our June 2021 program and $25 was used to repurchase shares pursuant to our September 2021 program. As of October 31, 2021, approximately $176 remained available under the June 2021 program and approximately $475 remained available under the September 2021 program.
