[1] Operating profit varies from the amounts previously reported on Forms 10-Q as a result of the reclassification of net gains from securities held in a separate trust from other non-operating income (expense), net to cost of sales in the fourth quarter of 2012 (Note 1).

[2] The fourth quarter of 2012 included a reduction in the income tax benefit of the U.S. manufacturing deduction primarily caused by $2.5 billion of discretionary pension contributions in the fourth quarter of 2012, which increased income tax expense by $59 million ($.18 per share).

[3] The sum of the quarterly earnings per share amounts do not equal the earnings per share amount included on our Statements of Earnings, primarily due to the timing of our share repurchases during 2012 and 2011.

[4] The second quarter of 2011 included a reduction in income tax expense of $89 million due to the resolution of certain tax matters (Note 7), and the second quarter and third quarter of 2011 included charges of $97 million ($63 million after tax) and $39 million ($25 million after tax) related to certain severance actions (Note 13).

[5] The third quarter of 2011 included a tax benefit of $66 million related to Savi which was recorded when the decision was made to dispose of the business (Note 14).
