[1] Due to rounding, the sum of the quarterly amounts may not equal the reported amounts for the year. The first quarter and second quarter amounts reflect application of discontinued operations accounting that was effective in the third quarter.

[2] In the first, second, third and fourth quarters of 2016, captions include pre-tax Merger, restructuring, and other operating expenses, net totaling $40 million, $(193) million, $31 million and $43 million, respectively, and asset impairments of $0 million, $0 million, $9 million and $6 million, respectively. The second quarter of 2016 Merger, restructuring and other operating expenses, net includes $250 million Termination Fee received pursuant to termination of the Staples Merger Agreement. The third quarter and fourth quarters include non-cash tax benefits of approximately $240 million and $140 million, respectively, from the release of valuation allowances on deferred tax assets.

[3] The amounts in the table above for the third quarter 2016 are as corrected to adjust for an error that was not material to the overall presentation. When the Company committed to a plan to sell substantially all of the business formerly reported as the International Division, it provided reference to the cumulative translation adjustment ("CTA") balance that existed at the end of the third quarter 2016, but did not include CTA in its impairment analysis. As a result, the loss amount of Discontinued operations, net of tax was overstated. The measurement has been corrected for the full year 2016 amounts. This correcting adjustment is provided below and would impact the same captioned line items in various portions of the third quarter financial statements by the same amount, as well as the current assets of discontinued operations, accumulated deficit and totals including those accounts.

[4] Due to rounding, the sum of the quarterly amounts may not equal the reported amounts for the year. The amounts reflect application of discontinued operations accounting.

[5] In the first, second, third and fourth quarters of 2015, captions include pre-tax Merger, restructuring, and other operating expenses, net totaling $29 million, $96 million, $79 million and $38 million, respectively, and asset impairments of $5 million, $4 million, $1 million and $3 million, respectively.

[6] The sum of the quarterly earnings per share does not equal the annual earnings per share due to differences in quarterly and annual weighted-average shares outstanding.
