Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivative Instruments and Hedging Activities Disclosure [Text Block] | Note 6. Derivative Instruments We engage in activities that expose us to market risks, including the effects of changes in fuel prices. Financial exposures are evaluated as an integral part of our risk management program, which seeks, from time-to-time, to reduce the potentially adverse effects that the volatility of fuel markets may have on operating results. In an effort to seek to reduce the variability of the ultimate cash flows associated with fluctuations in diesel fuel prices, we periodically enter into various derivative instruments, including forward futures swap contracts (which we refer to as "fuel hedge contracts"). Historically diesel fuel has not been a traded commodity on the futures market so heating oil has been used as a substitute, as prices for both generally move in similar directions. Recently, however, we have been able to enter into hedging contracts with respect to both heating oil and ultra low sulfur diesel ("ULSD"). Under these contracts, we pay a fixed rate per gallon of heating oil or ULSD and receive the monthly average price of New York heating oil per the New York Mercantile Exchange ("NYMEX") and Gulf Coast ULSD, respectively. The retrospective and prospective regression analyses provided that changes in the prices of diesel fuel and heating oil and diesel fuel and ULSD were each deemed to be highly effective based on the relevant authoritative guidance except for a small portion of our hedge contracts, which we determined to be ineffective on a prospective basis. Consequently, we recognized an approximately $0.3 million reduction of fuel expense in the first quarter of 2015 to mark the related liability to market. We do not engage in speculative transactions, nor do we hold or issue financial instruments for trading purposes. We recognize all derivative instruments at fair value on our condensed consolidated balance sheets. Our derivative instruments are designated as cash flow hedges, thus the effective portion of the gain or loss on the derivatives is reported as a component of accumulated other comprehensive loss and will be reclassified into earnings in the same period during which the hedged transaction affects earnings. The effective portion of the derivative represents the change in fair value of the hedge that offsets the change in fair value of the hedged item. To the extent the change in the fair value of the hedge does not perfectly offset the change in the fair value of the hedged item, the ineffective portion of the hedge is immediately recognized in our condensed consolidated statements of operations. Ineffectiveness is calculated using the cumulative dollar offset method as an estimate of the difference in the expected cash flows of the respective fuel hedge contracts (heating oil or ULSD) compared to the changes in the all-in cash outflows required for the diesel fuel purchases. At March 31, 2015, we had fuel hedge contracts on approximately 9.5 million gallons for the remainder of 2015, or approximately 22.9% of our projected remaining 2015 fuel requirements, approximately 12.1 million gallons for 2016, or approximately 21.9% of our projected 2016 fuel requirements, and approximately 7.6 million gallons for 2017, or approximately 13.7% of our projected 2017 fuel requirements. The fair value of the contracts that were in effect at March 31, 2015, of approximately $21.8 million is included in other liabilities in the consolidated balance sheet, net of cash collateral of $2.9 million provided by the Company to the counterparty, and is included in accumulated other comprehensive loss, net of tax. Changes in the fair values of these instruments can vary dramatically based on changes in the underlying commodity prices. For example, during the first quarter in 2015, market "spot" prices for ULSD peaked at a high of approximately $1.97 per gallon and hit a low price of approximately $1.44 per gallon. During the same 2014 quarter, market "spot" prices ranged from a high of $3.08 per gallon to a low of $2.85 per gallon. Market price changes can be driven by factors such as supply and demand, inventory levels, weather events, refinery capacity, political agendas, the value of the U.S. dollar, geopolitical events, and general economic conditions, among other items. Additionally, $3.4 million was reclassified from accumulated other comprehensive loss into our results of operations as additional fuel expense for the three months ended March 31, 2015, related to losses on contracts that expired. In addition to the $3.4 million reclassified from accumulated other comprehensive loss for the quarter ended March 31, 2015, related to losses on contracts that expired or were sold and for which we completed the forecasted transaction by purchasing the hedged diesel fuel, $0.3 million was recorded as a favorable adjustment to fuel expense related to contracts for which the hedging relationship was no longer deemed to be effective on a prospective basis. We had $0.1 million of unfavorable ineffectiveness recorded in accumulated other comprehensive loss on the contracts that existed at March 31, 2015. The ineffectiveness was calculated using the cumulative dollar offset method as an estimate of the difference in the expected cash flows of the respective fuel hedge contracts compared to the changes in the all-in cash outflows required for the diesel fuel purchases. Based on the amounts in accumulated other comprehensive loss as of March 31, 2015, and the expected timing of the purchases of the diesel hedged, we expect to reclassify losses of approximately $8.3 million, net of tax, on derivative instruments from accumulated other comprehensive loss into our results from operations during the next twelve months due to the actual diesel fuel purchases. The amounts actually realized will be dependent on the fair values as of the date of settlement. We perform both a prospective and retrospective assessment of the effectiveness of our hedge contracts at inception and quarterly, including assessing the possibility of counterparty default. If we determine that a derivative is no longer expected to be highly effective, we discontinue hedge accounting prospectively and recognize subsequent changes in the fair value of the hedge in earnings. As a result of our effectiveness assessment at inception and at March 31, 2015, we believe our hedge contracts have been and will continue to be highly effective in offsetting changes in cash flows attributable to the hedged risk, with the exception of the abovementioned contracts. Outstanding financial derivative instruments expose us to credit loss in the event of nonperformance by the counterparties to the agreements. We do not expect any of the counterparties to fail to meet their obligations. Our credit exposure related to these financial instruments is represented by the fair value of contracts reported as assets. To manage credit risk, we review each counterparty's audited financial statements and credit ratings and obtain references. If our fuel derivative instruments are in a net liability position with the counterparty and cash collateral is required, the cash collateral amounts provided are netted against the fair value of current outstanding derivative instruments. At March 31, 2015, and December 31, 2014, $2.9 million and $5.0 million cash collateral deposits, respectively, were provided by us in connection with our outstanding fuel derivative instruments.
