Derivatives and Hedging-Disclosures and Fair Value Measurements | 5) Derivatives and Hedging—Disclosures and Fair Value Measurements The Partnership uses derivative instruments such as futures, options and swap agreements in order to mitigate exposure to market risk associated with the purchase of home heating oil for price-protected customers, physical inventory on hand, inventory in transit, priced purchase commitments and internal fuel usage. The Partnership has elected not to designate its derivative instruments as hedging derivatives, but rather as economic hedges whose change in fair value is recognized in its statement of operations in the line item (Increase) decrease in the fair value of derivative instruments. Depending on the risk being economically hedged, realized gains and losses are recorded in cost of product, cost of installations and services, or delivery and branch expenses. As of September 30, 2016, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Partnership held the following derivative instruments that settle in future months to match anticipated sales: 9.9 million gallons of swap contracts with a notional value of $14.3 million and a fair value of $1.2 million, 6.8 million gallons of call options with a notional value of $13.8 million and a fair value of $0.3 million, 6.2 million gallons of put options with a notional value of $6.5 million and a fair value of $0.02 million, and 84.9 million net gallons of synthetic call options with an average notional value of $133.5 million and a fair value of $1.3 million. To hedge the inter-month differentials for its price-protected customers, its physical inventory on hand and inventory in transit, the Partnership, as of September 30, 2016, had 1.2 million gallons of purchased swap contracts with a notional value of $1.7 million and a fair value of $0.2 million, 4.4 million gallons of purchased future contracts with a notional value of $6.7 million and a fair value of $0.5 million, and 21.8 million gallons of sold future contracts with a notional value of $32.2 million and a fair value of $(2.1) million that settle in future months. In addition to the previously described hedging instruments, to lock-in the differential between high sulfur home heating oil and ultra low sulfur diesel, the Partnership as of September 30, 2016, had 7.9 million gallons of spread contracts (simultaneous long and short positions) with an average notional value of $10.8 million and a net fair value of $(0.04) million. To hedge its internal fuel usage and other related activities for fiscal 2017, the Partnership, as of September 30, 2016, had 5.7 million gallons of swap contracts with a notional value of $7.7 million and a fair value of $1.1 million that settle in future months. As of September 30, 2015, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Partnership held the following derivative instruments that settle in future months to match anticipated sales: 6.8 million gallons of swap contracts with a notional value of $12.7 million and a fair value of $(1.9) million, 7.2 million gallons of call options with a notional value of $17.1 million and a fair value of $0.1 million, 5.5 million gallons of put options with a notional value of $6.5 million and a fair value of $0.2 million, and 94.6 million net gallons of synthetic call options with an average notional value of $183.9 million and a fair value of $(12.0) million. To hedge the inter-month differentials for its price-protected customers, its physical inventory on hand and inventory in transit, the Partnership, as of September 30, 2015, had 1.8 million gallons of purchased swap contracts with a notional value of $3.4 million and a fair value of $(0.5) million, 8.9 million gallons of purchased future contracts with a notional value of $17.2 million and a fair value of $(2.0) million, and 32.0 million gallons of sold future contracts with a notional value of $54.1 million and a fair value of $2.9 million that settle in future months. In addition to the previously described hedging instruments, to lock-in the differential between high sulfur home heating oil and ultra low sulfur diesel, the Partnership as of September 30, 2015, had 12.3 million gallons of spread contracts (simultaneous long and short positions) with an average notional value of $18.3 million and a net fair value of $(0.5) million. To hedge its internal fuel usage and other related activities for fiscal 2016, the Partnership, as of September 30, 2015, had 6.0 million gallons of swap contracts with a notional value of $11.1 million and a fair value of $(1.9) million that settle in future months. The Partnership’s derivative instruments are with the following counterparties: Bank of America, N.A., Bank of Montreal, Cargill, Inc., Citibank, N.A., JPMorgan Chase Bank, N.A., Key Bank, N.A., Munich Re Trading LLC, Regions Financial Corporation, Societe Generale, and Wells Fargo Bank, N.A. The Partnership assesses counterparty credit risk and considers it to be low. We maintain master netting arrangements that allow for the non-conditionaloffsetting of amounts receivable and payable with counterparties to help manage our risks and record derivative positions on a net basis. The Partnership generally does not receive cash collateral from its counterparties and does not restrict the use of cash collateral it maintains at counterparties. At September 30, 2016, the aggregate cash posted as collateral in the normal course of business at counterparties was $2.9 million. Positions with counterparties who are also parties to our credit agreement are collateralized under that facility. As of September 30, 2016, $0.3 million of hedge positions and payable amounts were secured under the credit facility. FASB ASC 815-10-05 Derivatives and Hedging, established accounting and reporting standards requiring that derivative instruments be recorded at fair value and included in the consolidated balance sheet as assets or liabilities, along with qualitative disclosures regarding the derivative activity. To the extent derivative instruments designated as cash flow hedges are effective and the standard’s documentation requirements have been met, changes in fair value are recognized in other comprehensive income until the underlying hedged item is recognized in earnings. The Partnership has elected not to designate its derivative instruments as hedging instruments under this standard and the change in fair value of the derivative instruments is recognized in our statement of operations in the line item (Increase) decrease in the fair value of derivative instruments. Depending on the risk being hedged, realized gains and losses are recorded in cost of product, cost of installations and services, or delivery and branch expenses. FASB ASC 820-10 Fair Value Measurements and Disclosures, established a three-tier fair value hierarchy, which classified the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Partnership’s Level 1 derivative assets and liabilities represent the fair value of commodity contracts used in its hedging activities that are identical and traded in active markets. The Partnership’s Level 2 derivative assets and liabilities represent the fair value of commodity contracts used in its hedging activities that are valued using either directly or indirectly observable inputs, whose nature, risk and class are similar. No significant transfers of assets or liabilities have been made into and out of the Level 1 or Level 2 tiers. All derivative instruments were non-trading positions and were either a Level 1 or Level 2 instrument. The Partnership had no Level 3 derivative instruments. The fair market value of our Level 1 and Level 2 derivative assets and liabilities are calculated by our counter-parties and are independently validated by the Partnership. The Partnership’s calculations are, for Level 1 derivative assets and liabilities, based on the published New York Mercantile Exchange (“NYMEX”) market prices for the commodity contracts open at the end of the period. For Level 2 derivative assets and liabilities the calculations performed by the Partnership are based on a combination of the NYMEX published market prices and other inputs, including such factors as present value, volatility and duration. The Partnership had no assets or liabilities that are measured at fair value on a nonrecurring basis subsequent to their initial recognition. The Partnership’s financial assets and liabilities measured at fair value on a recurring basis are listed on the following table.
