[1] | As of January 1, 2016, we have adopted ASU 2015-03 and ASU 2015-15 with retrospective application. This resulted in a reclassification from other non-current assets to long-term debt, less current portion for debt issuance costs as of December 31, 2015. Refer to Note 2, “Summary of Significant Accounting Policies and Recently Issued Accounting Standards” of the Notes to the Consolidated Financial Statements for further details.
[2] | Property and equipment, net, and other non-current liabilities as of December 31, 2015, have been revised to properly reflect asset retirement obligations. This resulted in an increase to property and equipment, net and other non-current liabilities of $15.0 million. Certain amounts related to external payment terms were misclassified in the Consolidated Balance Sheet. The revision of this item resulted in a decrease in accounts payable and an increase in short-term borrowings of $6.3 million as of December 31, 2015. Additionally, due to changes in the accounting treatment of a factoring agreement the Company reclassified $6.7 million from cash and cash equivalents to other receivables. 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.
[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.
[4] | During the first quarter of 2015, the Company received the tax refund of $235.2 million related to the Settlement agreement payment. During the first quarter of 2014, we used $929.7 million of cash to fund the cash portion of the Settlement agreement and related accrued interest. 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.
[5] | Interest payments in 2014 include $416.6 million related to the Settlement agreement.

- Definition The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 718 -SubTopic 10 -Section 50 -Paragraph 2 -Subparagraph (f)(2)(ii) -URI http://asc.fasb.org/extlink&oid=6415400&loc=d3e5070-113901 + Details
