Earnings from continuing operations for the fourth quarter of 2010 also increased by $43 million ($.12 per share) due to the recognition of a tax benefit related to the retroactive extension of the research and development tax credit from January 1, 2010 through December 31, 2011 (see Note 9). Earnings from discontinued operations for the fourth quarter of 2010 included a gain of $184 million ($.51 per share) from the sale of EIG, and a decrease of $24 million ($.07 per share) associated with the planned sale of PAE. 2 It is our practice to close the books and records on the Sunday prior to the end of the calendar quarter to align our financial closing with our business processes. This practice only affects interim periods, as our fiscal year ends on December 31. 3 Earnings from continuing operations for the third quarter of 2010 included a charge of $178 million to cost of sales related to the VESP (see Note 3), which reduced net earnings by $116 million ($.32 per share). 4 Earnings from discontinued operations for the second quarter of 2010 included a tax benefit of $96 million due to the recognition of a deferred tax asset for PAE book and tax differences recorded when the decision was made to dispose of PAE (see Note 2). 5 Net sales and operating profit varies from the amount previously reported on Form 10-Q as a result of PAE and EIG being classified as discontinued operations in the second and third quarters of 2010, respectively. 6 Earnings from continuing operations for the first quarter of 2010 included an increase in income tax expense resulting from legislation that eliminates the tax deduction for benefit costs reimbursed under Medicare Part D (see Note 9), which reduced net earnings by $96 million ($.25 per share). 7 Earnings from continuing operations for the third quarter of 2009 included a reduction in income tax expense resulting from the closure of IRS examinations for tax years 2005-2007, which increased net earnings by $58 million ($.15 per share). 8 International sales, including export sales reflected in the "Foreign governments" and "Commercial and Other" categories, were $7.1 billion in 2010, $6.3 billion in 2009, and $5.7 billion in 2008. 9 Sales made to foreign governments through the U.S. Government, or "foreign military sales," are included in the "Foreign governments" category. 1139Information on Business Segments (Net Sales by Customer Category) (Details) (USD $)MillionsUnKnownUnKnownUnKnownfalsetrue
