[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] 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.
