Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivatives | Note 12—Derivatives Commodity Derivatives We utilize crude oil commodity derivative contracts to manage our price exposure in our inventory positions, future purchases of crude oil, future sales of refined products, and crude oil consumption in our refining process. The derivative contracts that we execute to manage our price risk include exchange traded futures, options, and OTC swaps. Our futures, options, and OTC swaps are marked-to-market and changes in the fair value of these contracts are recognized within Cost of revenues (excluding depreciation) on our consolidated statements of operations. We are obligated to repurchase the crude oil and refined products from J. Aron at the termination of the Supply and Offtake Agreements. We have determined that this obligation contains an embedded derivative, similar to forward purchase contracts of crude oil and refined products. As such, we have accounted for this embedded derivative at fair value with changes in the fair value recorded in Cost of revenues (excluding depreciation) on our consolidated statements of operations. We are also required under the Supply and Offtake Agreements to hedge the time spread between the period of crude oil cargo pricing and the month of delivery. We utilize OTC swaps to accomplish this. We have entered into forward purchase contracts for crude oil and forward sales contracts of refined products. We elect the normal purchases normal sales (“NPNS”) exception for all forward contracts that meet the definition of a derivative and are not expected to net settle. Any gains and losses with respect to these forward contracts designated as NPNS are not reflected in earnings until the delivery occurs. We elect to offset fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting agreement. Our consolidated balance sheets present derivative assets and liabilities on a net basis. Please read Note 13—Fair Value Measurements for the gross fair value and net carrying value of our derivative instruments. Our cash margin that is required as collateral deposits cannot be offset against the fair value of open contracts except in the event of default. At December 31, 2017, our open commodity derivative contracts represented:
• | futures sales contracts of 200 thousand barrels that economically hedge our crude oil and refined product inventory;
• | OTC swap purchases of 321 thousand barrels that economically hedge our crude oil and refined products month-end target inventory under our Supply and Offtake Agreements;
• | net OTC swaps and futures sales contracts of 140 thousand barrels that economically hedge our sales of refined products; and
• | option collars of 60 thousand barrels per month and OTC swaps of 15 thousand barrels per month through December 2018 that economically hedge our internally consumed fuel.
Interest Rate Derivatives We are exposed to interest rate volatility in the Supply and Offtake Agreements. We utilize interest rate swaps to manage our interest rate risk. As of December 31, 2017, we had locked in an average fixed rate of 1.1% in exchange for a floating interest rate indexed to the three-month LIBOR on an aggregate notional amount of $200.0 million. The interest rate swaps mature in February 2019 and March 2021. In June 2016, we completed the issuance and sale of an aggregate of $115.0 million principal amount of the 5.00% Convertible Senior Notes. Please read Note 11—Debt for further discussion. Upon redemption of our 5.00% Convertible Senior Notes on or after June 20, 2019 at our election, we are obligated to pay a make-whole premium equal to the present value of the remaining scheduled payments of interest on the 5.00% Convertible Senior Notes to be redeemed from the relevant redemption date to the maturity date of June 15, 2021. We have determined that the redemption option and the related make-whole premium represent an embedded derivative that is not clearly and closely related to the 5.00% Convertible Senior Notes. As such, we have accounted for this embedded derivative at fair value with changes in the fair value recorded in Interest expense and financing costs, net on our consolidated statements of operations. As of December 31, 2017, this embedded derivative was deemed to have a de minimis fair value. The following table provides information on the fair value amounts (in thousands) of these derivatives as of December 31, 2017 and 2016 and their placement within our consolidated balance sheets.
