(b) In May 2010, the Board of Directors authorized the repurchase of up to $3.0 billion of our common stock and in June 2012 increased its authorization for the repurchase of our common stock by an additional $3.0 billion. In October 2016, the Board of Directors approved a new stock repurchase program authorizing the repurchase of an additional $3.0 billion of our common stock and in November 2019 further increased its authorization for the repurchase of our common stock by an additional $7.0 billion. The stock repurchase program does not have an expiration date. Refer to “Item 1. Financial Statements-Note 16. Equity” for information on the share repurchase program. (c) In connection with the stock repurchase program, we executed accelerated share repurchase agreements (“ASR”) with Morgan Stanley & Co. LLC and Barclays Bank PLC to repurchase an aggregate $7 billion of common stock. The ASR was funded with cash on-hand. In November 2019, approximately 99 million shares of common stock, representing approximately 80% of the $7 billion aggregate repurchase price at the then current stock price, were delivered to the Company and included in treasury stock. The agreements are expected to settle during the second quarter of 2020, upon which additional shares of common stock may be delivered to the Company or, under certain circumstances, the Company may be required to make a cash payment or may elect to deliver shares of common stock to the counterparties. The total number of shares ultimately repurchased under the program will be determined upon final settlement and will be based on a discount to the volume-weighted average price of our common stock during the ASR period.
