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 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 awards granted to employees under stock-based compensation plans. The dilutive effect of these securities totaled 4.9 million shares and 4.6 million shares for the three and nine months ended September 30, 2012, respectively. The dilutive effect of these securities totaled 4.4 million shares and 4.8 million shares for the three and nine months ended September 30, 2011, respectively. The weighted-average diluted shares outstanding for the three and nine months ended September 30, 2012, exclude anti-dilutive stock options to purchase approximately 1.3 million shares and 2.7 million shares, respectively, because such options have exercise prices in excess of the average market price of the company’s common stock during the period. The weighted-average diluted shares outstanding for the three and nine months ended September 30, 2011, excludes anti-dilutive stock options to purchase approximately 3.6 million shares and 2.8 million shares, respectively.

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  Repurchased (in millions)	Average  Price Per Share(2)		Nine Months Ended September 30
						2012	2011
June 16, 2010(1)		$5,350	57.8		$58.46	13.6	28.4

(1) In June 2010, our board of directors authorized a share repurchase program of up to $2.0 billion of the company’s common stock. Following this initial authorization, our board of directors increased the remaining repurchase authorization to $4.0 billion in April 2011 and again increased the remaining repurchase authorization to $2.0 billion in September 2012. As of September 30, 2012, our repurchases under the program totaled $3.4 billion, and $2.0 billion remained under this share repurchase authorization. The repurchase program will expire when we have used all authorized funds for repurchase.

(2) Includes commissions paid.

Share repurchases take place at management's discretion under pre-established, non-discretionary programs, depending on market conditions, in the open market, or 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. Since the spin-off we have repurchased approximately 54 million shares of our common stock, and as of September 30, 2012, approximately 34 million shares remained under the Private Letter Ruling limitation. Cash available from unusual transactions, such as the disposition of significant assets, should they arise, can be used to repurchase additional shares.

In May 2011, the company increased the quarterly common stock dividend to $0.50 per share from the previous amount of $0.47 per share.
