Shareholders' Equity

Share Repurchases
In October 2018, our Board of Directors authorized up to $1.0 billion of share repurchases with no expiration date, subject to the Board of Directors’ approval of the pricing parameters and amount that may be repurchased under each specific share repurchase program (the "2018 Authorization"). We did not repurchase any shares during the three and nine months ended October 2, 2021 or September 26, 2020.
