Financial Instruments	3) FINANCIAL INSTRUMENTS *Fair Value Hedges:* During 2014, 2013 and 2012, we had no fair value hedges outstanding. *Cash Flow Hedges:* We manage our ratio of fixed and floating rate debt with the objective of achieving a mix that management believes is appropriate. To manage this risk in a cost-effective manner, we, from time to time, enter into interest rate swap agreements in which we agree to exchange various combinations of fixed and/or variable interest rates based on agreed upon notional amounts. We account for our derivative and hedging activities using the Financial Accounting Standard Board’s (“FASB”) guidance which requires all derivative instruments, including certain derivative instruments embedded in other contracts, to be carried at fair value on the balance sheet. For derivative transactions designated as hedges, we formally document all relationships between the hedging instrument and the related hedged item, as well as its risk-management objective and strategy for undertaking each hedge transaction. Derivative instruments designated in a hedge relationship to mitigate exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Cash flow hedges are accounted for by recording the fair value of the derivative instrument on the balance sheet as either an asset or liability, with a corresponding amount recorded in accumulated other comprehensive income (“AOCI”) within shareholders’ equity. Amounts are reclassified from AOCI to the income statement in the period or periods the hedged transaction affects earnings. We use interest rate derivatives in our cash flow hedge transactions. Such derivatives are designed to be highly effective in offsetting changes in the cash flows related to the hedged liability. For derivative instruments designated as cash flow hedges, the ineffective portion of the change in expected cash flows of the hedged item are recognized currently in the income statement. For hedge transactions that do not qualify for the short-cut method, at the hedge’s inception and on a regular basis thereafter, a formal assessment is performed to determine whether changes in the fair values or cash flows of the derivative instruments have been highly effective in offsetting changes in cash flows of the hedged items and whether they are expected to be highly effective in the future. The fair value of interest rate swap agreements approximates the amount at which they could be settled, based on estimates obtained from the counterparties. We assess the effectiveness of our hedge instruments on a quarterly basis. We performed periodic assessments of the cash flow hedge instruments during 2014 and 2013 and determined the hedges to be highly effective. We also determined that any portion of the hedges deemed to be ineffective was de minimis and therefore there was no material effect on our consolidated financial position, operations or cash flows. The counterparties to the interest rate swap agreements expose us to credit risk in the event of nonperformance. However, at December 31, 2014 and 2013, each swap agreement entered into by us was in a liability position which would require us to make the settlement payments to the counterparties. We do not anticipate nonperformance by our counterparties. We do not hold or issue derivative financial instruments for trading purposes. During 2010, we entered into four forward starting interest rate swaps whereby we pay a fixed rate on a total notional amount of $600 million and receive three-month LIBOR. Each of the four swaps became effective in December, 2011 and will mature in May, 2015. The average fixed rate payable on these swaps is 2.38%. We also entered into six forward starting interest rate swaps in 2011 whereby we pay a fixed rate on a total notional amount of $425 million and receive three-month LIBOR. Three of these swaps with a total notional amount of $225 million became effective in March, 2011 and will mature in May, 2015. The average fixed rate payable on these swaps is 1.91%. The three remaining interest rate swaps with total notional amounts of $75 million, $25 million and $100 million became effective in December, 2011 and had corresponding fixed rates of 1.32%, 1.96% and 2.50%. The $75 million, $25 million and $100 million interest rate swaps matured in December, 2012, December, 2013 and December, 2014, respectively. During 2011, we entered into a forward starting interest rate cap, which is now expired, on a total notional amount of $450 million from December, 2011 to December, 2012 reducing to $400 million from December, 2012 to December, 2013 whereby we paid a premium of $740,000 in exchange for the counterparty agreeing to pay the difference between 7.00% and three-month LIBOR if the three-month LIBOR rate rises above 7.00% during the term of the cap. The three-month LIBOR never reached 7.00% during the term of the cap, which expired in December, 2013, and therefore no payment was made to us. We measure our interest rate swaps at fair value on a recurring basis. The fair value of our interest rate swaps is based primarily on quotes from banks. We consider those inputs to be “level 2” in the fair value hierarchy as outlined in the authoritative guidance for disclosures in connection with derivative instruments and hedging activities. The fair value of our interest rate swaps was a liability of $6 million at December 31, 2014, all of which is included in other current liabilities. At December 31, 2013, the fair value of our interest rate swaps was a liability of $24 million, of which $19 million was included in other current liabilities and $5 million was included in other noncurrent liabilities on the accompanying balance sheet.
