Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements The carrying amounts of cash and cash equivalents, accounts receivable, net, accounts payable and accrued expenses and other current liabilities approximate fair value based on the short‑term maturities of these instruments. The carrying values of our debt and notes receivables approximate fair value since these instruments bear interest either at variable rates or fixed rates which are not materially different than market rates. Based on the fair value hierarchy, our debt of $0.9 billion and $1.2 billion as of December 31, 2017 and December 31, 2016, respectively, and our notes receivable of $44.9 million and $16.9 million as of December 31, 2017 and December 31, 2016, respectively are categorized in Level 2. Recurring Fair Value Measurements. The following table presents information about our gross assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2017 and 2016 (in millions):

There were no transfers between Level 1 and Level 2 during the periods presented. The fair values of our commodity contracts measured using Level 3 inputs were not material at December 31, 2017 and 2016, respectively. For our derivative contracts, we may enter into master netting, collateral and offset agreements with counterparties. These agreements provide us the ability to offset a counterparty’s rights and obligations, request additional collateral when necessary or liquidate the collateral in the event of counterparty default. We net fair value of cash collateral paid or received against fair value amounts recognized for net derivative positions executed with the same counterparty under the same master netting or offset agreement. The following tables summarize those commodity derivative balances subject to the right of offset as presented on our consolidated balance sheet. We have elected to offset the recognized fair value amounts for multiple derivative instruments executed with the same counterparty in our financial statements when a legal right of offset exists.

At December 31, 2017 and 2016, we did not present any amounts gross on our consolidated balance sheet where we had the right of setoff. Concentration of Credit Risk The individual over-the-counter (OTC) counterparty exposure is managed within predetermined credit limits and includes the use of cash-call margins when appropriate, thereby reducing the risk of significant nonperformance. At December 31, 2017, two counterparties each represented over 10% of our credit exposure to OTC derivative counterparties for a total credit risk of 24.2 million.
