FAIR VALUE MEASUREMENTS

6 Months Ended

Jun. 30, 2015

We apply the authoritative accounting provisions for measuring fair value to our financial instruments and related disclosures, which include cash and cash equivalents, accounts receivable, accounts payable, debt, and derivative instruments. We define fair value as an exit price representing the expected amount we would receive to sell an asset or pay to transfer a liability in an orderly transaction with market participants at the measurement date.

We employ a hierarchy which prioritizes the inputs we use to measure recurring fair value into three distinct categories based upon whether such inputs are observable in active markets or unobservable. We classify assets and liabilities in their entirety based on the lowest level of input that is significant to the fair value measurement. Our methodology for categorizing assets and liabilities that are measured at fair value pursuant to this hierarchy gives the highest priority to unadjusted quoted prices in active markets and the lowest level to unobservable inputs, summarized as follows:


•	Level 1 — Quoted prices in active markets for identical assets or liabilities.


•	Level 2 — Other significant observable inputs (including quoted prices in active markets for similar assets or liabilities).


•	Level 3 — Significant unobservable inputs (including our own assumptions in determining fair value).

We use the cost, income or market valuation approaches to estimate the fair value of our assets and liabilities when insufficient market-observable data is available to support our valuation assumptions.

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, and our credit facilities as presented on our consolidated balance sheets approximate fair value due to the short-term nature of these items and, with respect to our credit facilities, the frequent re-pricing of the underlying obligations. The fair value of our historical accounts receivable with affiliates and payables with affiliates cannot be determined due to the related party nature of these items.
