Fair Value Disclosures [Abstract] |
Fair Value | Fair Value Fair Value Methods and Assumptions - Financial Assets and Liabilities. We used the following methods and assumptions in estimating fair value of our financial assets and liabilities:
• | Energy commodity derivatives contracts. These include exchange-traded futures contracts related to petroleum products. These contracts are carried at fair value on our consolidated balance sheets and are valued based on quoted prices in active markets. See Note 9 – Derivative Financial Instruments for further disclosures regarding these contracts.
• | Interest rate contracts. These include forward-starting interest rate hedge agreements to protect against the risk of variability of interest payments on future debt. These contracts are carried at fair value on our consolidated balance sheets and are valued based on an assumed exchange, at the end of each period, in an orderly transaction with a participant in the market in which the financial
instrument is traded. The exchange value was calculated using present value techniques on estimated future cash flows based on forward interest rate curves. See Note 9 – Derivative Financial Instruments for further disclosures regarding these contracts.
• | Basis Derivative Agreement. During 2019, we entered into a basis derivative agreement with a joint venture co-owner’s affiliate, and, contemporaneously, that affiliate entered into an intrastate transportation services agreement with the joint venture. Settlements under the basis derivative agreement are determined based on the basis differential of crude oil prices at different market locations and a notional volume of 30,000 barrels per day (see Note 9 - Derivative Financial Instruments for further disclosures regarding this agreement). The fair value of this derivative was calculated based on observable market data inputs, including published commodity pricing data and market interest rates. The key inputs in the fair value calculation include the forward price curves for crude oil, the implied forward correlation in crude oil prices between West Texas and the Houston Gulf Coast, and the implied forward volatility for crude oil futures contracts.
• | Long-term receivables. These primarily include payments receivable under a sales-type leasing arrangement and cost reimbursement payments receivable. These receivables were recorded at fair value on our consolidated balance sheets, using then-current market rates to estimate the present value of future cash flows.
• | Guarantees. At December 31, 2018, these guarantees primarily included an indemnification agreement we entered into with an affiliate of OMERS, the defined benefit pension plan for municipal employees in Ontario, Canada, in connection with the partial sale of our interest in BridgeTex. This indemnification was recorded at fair value on our consolidated balance sheets upon initial recognition, using probability-weighted potential outcome scenarios to estimate our possible liability for specific events covered by this indemnification. In first quarter 2019, certain litigation subject to the indemnification agreement was settled, which resulted in our paying $5.0 million under the indemnification agreement and recognizing the reduction of the remaining $11.0 million liability as an additional gain on disposition of assets on our consolidated statements of income.
• | Debt. The fair value of our publicly traded notes was based on the prices of those notes at December 31, 2018 and June 30, 2019; however, where recent observable market trades were not available, prices were determined using adjustments to the last traded value for that debt issuance or by adjustments to the prices of similar debt instruments of peer entities that are actively traded. The carrying amount of borrowings, if any, under our revolving credit facility and our commercial paper program approximates fair value due to the frequent repricing of these obligations.
