[3] Certain amounts related to external payment terms were misclassified in the Consolidated Balance Sheet as of December 31, 2015 and 2014. The revision of this item resulted in a decrease in accounts payable and an increase in short-term borrowings in each year. Additionally, due to changes in the accounting treatment of a factoring agreement the Company reclassified amounts from cash and cash equivalents to other receivables for the years ended December 31, 2015 and 2014. See Note 2 “Summary of Significant Accounting Policies and Recently Issued Accounting Standards” of the Notes to Consolidated Financial Statements under the heading “Reclassifications and Revisions” for further discussion of the revisions.

We recorded an excess tax benefit of $46.2 million as an out-of-period adjustment in December 2015 and $37.7 million in December 2014 related to the 18 million shares of Common Stock issued in connection with the Settlement agreement. See Note 16 “Income Taxes” of the Notes to Consolidated Financial Statements for further discussion of the out-of-period adjustment.
