Fair Value Hedges

Interest Rate Swaps

In prior years, we entered into interest rate swaps to maintain a portion of our debt obligations at variable market interest rates. We designated these interest rate swaps as fair value hedges of our fixed-rate senior notes. Fair value hedge accounting for interest rate swap contracts increased the carrying value of our debt instruments by $51 million as of June 30, 2014 and $59 million as of December 31, 2013. These fair value adjustments to long-term debt are being amortized as a reduction to interest expense using the effective interest method over the remaining term of the related senior notes, which extend through 2028. We recognized benefits to interest expense associated with the amortization of our terminated interest rate swaps of $3 million and $5 million for the three-month periods ended June 30, 2014 and 2013, respectively, and $8 million and $10 million for the six-month periods ended June 30, 2014 and 2013, respectively.

Cash Flow Hedges

Forward-Starting Interest Rate Swaps

During the first quarter of 2014, forward-starting interest rate swaps with a notional value of $175 million matured and we paid cash of $36 million to settle the associated liabilities. These swaps were designated as cash flow hedges and had been executed in prior years to hedge the risk of changes in semi-annual interest payments due to fluctuations in the forward ten-year LIBOR swap rate for an anticipated fixed-rate debt issuance that occurred in May 2014. Accordingly, the effective portion of the loss associated with the matured forward-starting swaps has been deferred as a component of “Accumulated other comprehensive income” and is being amortized to interest expense over the ten-year term of the related senior notes. The ineffectiveness realized during the second quarter of 2014 was not material.

At June 30, 2014 and December 31, 2013, our “Accumulated other comprehensive income” included $53 million and $34 million, respectively, of after-tax deferred losses related to all terminated swaps. These losses are being amortized as an increase to interest expense using the effective interest method over the ten-year term of the related senior notes, which extend through 2024. As of June 30, 2014, $11 million (on a pre-tax basis) is scheduled to be reclassified as an increase to interest expense over the next 12 months for these previously terminated swaps.

Foreign Currency Derivatives

We use foreign currency exchange rate derivatives to hedge our exposure to fluctuations in exchange rates for anticipated intercompany cash transactions between WM Holdings and its Canadian subsidiaries. As of June 30, 2014, we had foreign exchange cross currency swaps outstanding for all of the anticipated cash flows associated with intercompany loans from WM Holdings to the wholly-owned Canadian subsidiaries. The hedged cash flows as of June 30, 2014 include C$370 million of total notional value. The scheduled principal payments of the loan and the related swaps are as follows: C$70 million due on October 31, 2016, C$150 million due on October 31, 2017 and C$150 million due on October 31, 2018. We designated these cross currency swaps as cash flow hedges. Gains or losses resulting from the remeasurement of the underlying non-functional currency intercompany loan are recognized in current earnings in the same financial statement line item as offsetting gains or losses on the related cross currency swaps.

Electricity Commodity Derivatives

We use short-term “receive fixed, pay variable” electricity commodity swaps to reduce the variability in our revenues and cash flows caused by fluctuations in the market prices for electricity. We hedged 1.73 million megawatt hours, or approximately 56%, of Wheelabrator’s full year 2013 merchant electricity sales and the swaps executed through June 30, 2014 are expected to hedge approximately 482,000 megawatt hours, or approximately 16%, of Wheelabrator’s full year 2014 merchant electricity sales. For each of the three- and six-month periods ended June 30, 2014, we hedged 17% of Wheelabrator’s merchant electricity sales. For the three- and six-month periods ended June 30, 2013, we hedged 56% and 54%, respectively, of Wheelabrator’s merchant electricity sales.

There was no significant ineffectiveness associated with our cash flow hedges during the three and six months ended June 30, 2014 or 2013. Refer to Note 11 for information regarding the impacts of our cash flow derivatives on our comprehensive income and results of operations.

Credit-Risk-Related Contingent Features

Our interest rate derivative instruments have in the past, and may in the future, contain provisions related to the Company’s credit rating. These provisions generally provide that if the Company’s credit rating were to fall to specified levels below investment grade, the counterparties have the ability to terminate the derivative agreements, resulting in settlement of all affected transactions. As of June 30, 2014 and December 31, 2013, we did not have any interest rate derivatives outstanding that contained these credit-risk-related features.
