Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements Assets and Liabilities Measured at Fair Value on a Recurring Basis Common Stock Warrants During January and March 2020, one of our stockholders and its affiliates exercised 354,350 common stock warrants with a fair value of $3.9 million. As a result of this cashless transaction, 350,542 shares of common stock were issued. As of March 31, 2021, we had no common stock warrants outstanding. Derivative Instruments We utilize commodity derivative contracts to manage our price exposure to our inventory positions, future purchases of crude oil, future purchases and sales of refined products, and cost of crude oil consumed in the refining process. We may utilize interest rate swaps to manage our interest rate risk. We classify financial assets and liabilities according to the fair value hierarchy. Financial assets and liabilities classified as Level 1 instruments are valued using quoted prices in active markets for identical assets and liabilities. These include our exchange traded futures. Level 2 instruments are valued using quoted prices for similar assets and liabilities in active markets and inputs other than quoted prices that are observable for the asset or liability. Our Level 2 instruments include OTC swaps and options. These derivatives are valued using market quotations from independent price reporting agencies and commodity exchange price curves that are corroborated with market data. Level 3 instruments are valued using significant unobservable inputs that are not supported by sufficient market activity. The valuation of the embedded derivatives related to our J. Aron repurchase and MLC terminal obligations is based on estimates of the prices and differentials assuming settlement at the end of the reporting period. Estimates of the J. Aron and MLC settlement prices are based on observable inputs, such as Brent and West Texas Intermediate Crude Oil (“WTI”) indices, and unobservable inputs, such as contractual price differentials as defined in the Supply and Offtake Agreements and Washington Refinery Intermediation Agreement. Such contractual differentials vary by location and by the type of product and range from a discount of $15.49 per barrel to a premium of $14.05 per barrel as of March 31, 2021. Contractual price differentials are considered unobservable inputs; therefore, these embedded derivatives are classified as Level 3 instruments. We did not have other commodity derivatives classified as Level 3 at March 31, 2021 or December 31, 2020. Please read Note 10—Derivatives for further information on derivatives. Gross Environmental credit obligations Estimates of our gross environmental credit obligations are based on the amount of RINs or other environmental credits required to comply with U.S. Environmental Protection Agency (“EPA”) regulations and the market prices of those RINs or other environmental credits as of the end of the reporting period. The gross environmental credit obligations are classified as Level 2 instruments as we obtain the pricing inputs for our RINs and other environmental credits from brokers based on market quotes on similar instruments. Please read Note 13—Commitments and Contingencies for further information on the EPA regulations related to greenhouse gases.

_________________________________________________________ (1)The fair value measurements of the 5.00% Convertible Senior Notes, 7.75% Senior Secured Notes, Term Loan B Facility, and 12.875% Senior Secured Notes are considered Level 2 measurements in the fair value hierarchy as discussed below. (2)The fair value measurements of the ABL Credit Facility, Mid Pac Term Loan, Retail Property Term Loan, and PHL Term Loan are considered Level 3 measurements in the fair value hierarchy. (3)The carrying value of the 5.00% Convertible Senior Notes excludes the fair value of the equity component, which was classified as equity upon issuance. The fair value of the 5.00% Convertible Senior Notes was determined by aggregating the fair value of the liability and equity components of the notes. The fair value of the liability component of the 5.00% Convertible Senior Notes was determined using a discounted cash flow analysis in which the projected interest and principal payments were discounted at an estimated market yield for a similar debt instrument without the conversion feature. The equity component was estimated based on the Black-Scholes model for a call option with strike price equal to the conversion price, a term matching the remaining life of the 5.00% Convertible Senior Notes, and an implied volatility based on market values of options outstanding as of March 31, 2021. The fair value of the 5.00% Convertible Senior Notes is considered a Level 2 measurement in the fair value hierarchy. The fair value of the 7.75% Senior Secured Notes, Term Loan B Facility, and 12.875% Senior Secured Notes were determined using a market approach based on quoted prices. The inputs used to measure the fair value are classified as Level 2 inputs within the fair value hierarchy because the 7.75% Senior Secured Notes, Term Loan B Facility, and 12.875% Senior Secured Notes may not be actively traded. The carrying values of our Retail Property, Mid Pac, and PHL Term Loans were determined to approximate fair value as of December 31, 2020. The Retail Property and PHL Term Loans were repaid in full on February 23, 2021 and the Mid Pac Term Loan was repaid in full on March 12, 2021. The fair value of all non-derivative financial instruments recorded in current assets, including cash and cash equivalents, restricted cash, and trade accounts receivable, and current liabilities, including accounts payable, approximate their carrying value due to their short-term nature.
