The Company 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. 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. The Company has elected not to designate its commodity derivative instruments as hedging derivatives, but rather as economic hedges whose change in fair value is recognized in its statement of operations in the caption “(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 March 31, 2021, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Company held the following derivative instruments that settle in future months to match anticipated sales: 6.4 million gallons of swap contracts, 4.5 million gallons of call options, 2.8 million gallons of put options, and 54.4 million net gallons of synthetic call options. To hedge the inter-month differentials for its price-protected customers, its physical inventory on hand and inventory in transit, the Company, as of March 31, 2021, held 3.8 million gallons of long future contracts and 25.5 million gallons of short future contracts that settle in future months. To hedge its internal fuel usage and other activities for fiscal 2021, the Company held 0.5 million gallons of call options and swap contracts that settle in future months.

As of March 31, 2020, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Company held the following derivative instruments that settle in future months to match anticipated sales: 8.9 million gallons of swap contracts, 5.3 million gallons of call options, 4.0 million gallons of put options, and 52.8 million net gallons of synthetic call options. To hedge the inter-month differentials for its price-protected customers, its physical inventory on hand and inventory in transit, the Company, as of March 31, 2020, held 32.6 million gallons of long future contracts, and 52.1 million gallons of short future contracts that settle in future months. To hedge its internal fuel usage and other activities for fiscal 2020 and 2021, the Company held 7.3 million gallons of call options and swap contracts and 0.2 million gallons of short swap contracts that settle in future months.

As of March 31, 2021, the Company has interest rate swap agreements in order to mitigate exposure to market risk associated with variable rate interest on $61.5 million, or 53%, of its long term debt. The Company has designated its interest rate swap agreements as cash flow hedging derivatives. To the extent these derivative instruments are effective and the accounting 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. As of March 31, 2021 the fair value of the swap contracts was $(2.1) million. As of September 30, 2020, the notional value of the swap contracts was $64.0 million and the fair value of the swap contracts was $(3.1) million. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of the swap contracts.

The Company’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., Toronto-Dominion Bank and Wells Fargo Bank, N.A. The Company assesses counterparty credit risk and considers it to be low. We maintain master netting arrangements that allow for the non-conditional offsetting of amounts receivable and payable with counterparties to help manage our risks and record derivative positions on a net basis. The Company generally does not receive cash collateral from its counterparties and does not restrict the use of cash collateral it maintains at counterparties. At March 31, 2021, the aggregate cash posted as collateral in the normal course of business at counterparties was $1.8 million and recorded in “Prepaid expense and other current assets.” Positions with counterparties who are also parties to our credit agreement are collateralized under that facility. As of March 31, 2021, no hedge positions and payable amounts were secured under the credit facility.

The Company’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 Company’s Level 2 derivative assets and liabilities represent the fair value of commodity and interest rate 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 Company 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 Company. The Company’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 Company are based on a combination of the NYMEX published market prices and other inputs, including such factors as present value, volatility and duration.

The Company had no assets or liabilities that are measured at fair value on a nonrecurring basis subsequent to their initial recognition. The Company’s commodity financial assets and liabilities measured at fair value on a recurring basis are listed on the following table.
