Earnings (loss) per basic share is computed based on the weighted-average number of common shares. Earnings (loss) per diluted share include the weighted-average effect of dilutive restricted stock and options on the weighted-average shares outstanding.

The following table provides the weighted-average shares utilized for the calculation of basic and diluted earnings (loss) per share for the second quarter and year-to-date 2021 and 2020:


	Second Quarter		Year-to-Date
	2021	2020	2021	2020
	(in millions)

Common Shares	288	286	288	285
Treasury Shares	(13)	(8)	(11)	(8)
Basic Shares	275	278	277	277
Effect of Dilutive Restricted Stock and Options	5	—	5	—
Diluted Shares	280	278	282	277
Anti-dilutive Options and Awards (a)	1	11	1	12

(a)These options and awards were excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive. For 2020, the dilutive impact of all outstanding options and awards were excluded from dilutive shares as a result of the Company's net loss for the period.

In March 2021, the Company's Board of Directors authorized a new $500 million share repurchase plan, which replaced the $79 million remaining under the March 2018 repurchase program. Pursuant to the Board's authorization, the Company entered into a Rule 10b5-1 purchase plan to effectuate share repurchases for the first $250 million. In May 2021, the Company initiated a second $250 million Rule 10b5-1 purchase plan to effectuate the remaining share repurchases under the March 2021 repurchase plan.

In July 2021, the Company's Board of Directors authorized a new $1.5 billion share repurchase program, which replaced the $36 million remaining under the March 2021 repurchase program. Under the authorization of this program, the Company entered into a stock repurchase agreement with its former Chief Executive Officer and certain of his affiliated entities pursuant to which the Company repurchased 10 million shares of its common stock for an aggregate purchase price of $730 million in July 2021.

The Company repurchased the following shares of its common stock during year-to-date 2021:


Repurchase Program	Amount Authorized		Shares Repurchased	Amount Repurchased		Average Stock Price
	(in millions)		(in thousands)	(in millions)
March 2021	$	500	6,996	$	464	$	66.30
July 2021	$	1,500	10,000	$	730	$	73.01

Subsequent to July 31, 2021, the Company repurchased an additional 1.0 million shares of its common stock for $65 million under the July 2021 Program.

In accordance with the Company's Board of Directors' resolution, shares of common stock repurchased under the July 2021 Program will be automatically retired and cancelled upon repurchase. As a result, the Company retired the 10 million shares repurchased under the July 2021 Program in the second quarter of 2021, which resulted in a reduction of $5 million in the par value of Common Stock, $32 million in Paid-in Capital and $693 million in Retained Earnings.
