Earnings Per Share [Abstract]

EARNINGS PER SHARE, SHARE REPURCHASES AND DIVIDENDS ON COMMON STOCK

EARNINGS PER SHARE, SHARE REPURCHASES AND DIVIDENDS ON COMMON STOCK

Basic Earnings Per Share

Basic earnings per share amounts from both continuing and discontinued operations are calculated by dividing the respective earnings by the weighted-average number of shares of common stock outstanding during each period.

Diluted Earnings Per Share

Diluted earnings per share includes the dilutive effect of stock awards granted to employees under stock-based compensation plans. The dilutive effect of these securities totaled 4.9 million shares and 5.1 million shares for the three months ended March 31, 2012 and 2011, respectively. The weighted-average diluted shares outstanding for the three months ended March 31, 2012 and 2011, exclude anti-dilutive stock options to purchase approximately 2.8 million shares for both periods because such options have exercise prices in excess of the average market price of the company’s common stock during the period.

Share Repurchases

The table below summarizes the company’s share repurchases:

						Shares Repurchased (in millions)
Repurchase Program Authorization Date	Amount Authorized (in millions)		Total Shares Retired (in millions)	Average  Price Per Share(2)		Three Months Ended March 31
						2012	2011
June 16, 2010(1)		$4,245	48.5		$57.63	4.4	0.1

(1) On June 16, 2010, the company’s board of directors authorized a share repurchase program of up to $2.0 billion of the company’s common stock. On April 25, 2011, after the company had repurchased shares totaling $245 million, the company’s board of directors authorized an increase to the remaining share repurchase authorization to $4.0 billion. As of March 31, 2012, the company had $1.4 billion remaining under this authorization for share repurchases.

(2) Calculated as the average price paid per share under the respective repurchase program, including commissions paid.

Share repurchases take place at management's discretion or under pre-established, non-discretionary programs, depending on market conditions, in the open market, and in privately negotiated transactions. The company retires its common stock upon repurchase and has not made any purchases of common stock other than in connection with these publicly announced repurchase program authorizations. In connection with the spin-off of the former shipbuilding business (see Note 3), the company obtained a Private Letter Ruling from the Internal Revenue Service that generally limits our share repurchases to approximately 88 million shares within two years of the spin-off. The limitation expires on March 31, 2013. Due to share repurchases subsequent to the spin-off, the remaining number of shares that we can repurchase under this share repurchase limitation as of March 31, 2012, was approximately 43 million shares. Cash available from unusual transactions, such as the disposition of significant assets, should they arise, can be used to repurchase additional shares.

Dividends on Common Stock

Effective for shareholders of record as of May 31, 2011, the company increased the common stock dividend to $0.50 per share, an increase from the previous amount of $0.47 per share.
