Fair Value Measurements |
Fair Value Measurements | 10. 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. We believe the carrying values of our debt and notes receivable approximate fair value since these instruments bear interest either at variable rates or fixed rates which are not significantly different than market rates. Based on the fair value hierarchy, our debt of $689.9 million as of December 31, 201 4 and $463.7 million as of December 31, 201 3 and our notes receivable of $7.0 million as of December 31, 201 4 and $20.9 million as of December 31, 201 3 are categorized in Level 3. The following table presents information about our assets and liabilities that are measured at fair value on a recurring basis as of December 31, 201 4 and 201 3 (in thousands):

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. As of December 31, 2014, we had $301.0 million of cash collateral deposits held by financial counterparties, of which $274.3 million have been offset against the total amount of commodity fair value liabilities in the above table and the remaining $26.7 million is included in other current assets in the accompanying consolidated balance sheets. In addition, as of December 31, 2014, we have offset $46.7 million of cash collateral received from customers against the total amount of commodity fair value assets in the above table. As of December 31, 2013, we had $13.0 million of cash collateral deposits held by financial counterparties and there were no significant amounts of cash collateral that were offset against the total commodity fair value liabilities in the above table. Additionally, as of December 31, 2013, we had offset $4.7 million of cash collateral deposits received from customers against the total amount of commodity fair value assets in the above table. The following table presents information about our assets and liabilities that are measured at fair value on a recurring basis that utilized Level 3 inputs for the periods presented (in thousands):

The nature of inputs that are considered Level 3 are model inputs. Commodity contracts categorized in Level 3 are placed there due to the significance of the unobservable model inputs to their respective fair values. The unobservable model inputs, such as basis differentials, are based on the difference between the historical prices of our prior transactions and underlying observable data as well as certain risk related to non-performance. The effect on our income before income taxes of a 10% change in the model input for non-performance risk would not be significant.
