Fair Value Measurements
Fair Value Measurements

The fair value of assets and liabilities are determined using either unadjusted quoted prices in active markets (Level 1) or pricing inputs that are observable (Level 2) whenever that information is available and using unobservable inputs (Level 3) to estimate fair value only when relevant observable inputs are not available. NEP uses several different valuation techniques to measure the fair value of assets and liabilities relying primarily on the market approach of using prices and other market information for identical and/or comparable assets and liabilities for those assets and liabilities that are measured at fair value on a recurring basis. Certain financial instruments may be valued using multiple inputs including discount rates, counterparty credit ratings and credit enhancements. NEP’s assessment of the significance of any particular input to the fair value measurement requires judgment and may affect the placement of those assets and liabilities within the fair value hierarchy levels. Non-performance risk, including the consideration of a credit valuation adjustment, is also considered in the determination of fair value for all assets and liabilities measured at fair value. Transfers between fair value hierarchy levels occur at the beginning of the period in which the transfer occurred.

Cash Equivalents and Restricted Cash Equivalents - The fair value of money market funds that are included in cash and cash equivalents, restricted cash and other non-current assets on the condensed consolidated balance sheets is estimated using a market approach based on current observable market prices.

Interest Rate and Foreign Currency Contracts - NEP estimates the fair value of its derivatives using an income approach based on a discounted cash flows valuation technique utilizing the net amount of estimated future cash inflows and outflows related to the agreements. The primary inputs used in the fair value measurements include the contractual terms of the derivative agreements, current interest rates, foreign currency exchange rates and credit profiles. The significant inputs for the resulting fair value measurement are market-observable inputs and the measurements are reported as Level 2 in the fair value hierarchy.

NEP’s financial assets and liabilities and other fair value measurements made on a recurring basis by fair value hierarchy level are as follows:

At March 31, 2018 and December 31, 2017, approximately $9 million and $7 million, respectively, of restricted cash equivalents are included in other non-current assets on NEP's condensed consolidated balance sheets.

Financial Instruments Recorded at Other than Fair Value - The carrying amount of short-term debt approximates its fair value. The carrying amounts and estimated fair values of other financial instruments recorded at other than fair value are as follows:

(a)
At March 31, 2018 and December 31, 2017, approximately $3,051 million and $3,552 million, respectively, of the fair value is estimated using a market approach based on quoted market prices for the same or similar issues (Level 2); the balance is estimated using an income approach utilizing a discounted cash flow valuation technique, considering the current credit profile of the debtor (Level 3). The March 31, 2018 carrying value excludes debt totaling approximately $690 million which is reflected in liabilities associated with assets held for sale on NEP's condensed consolidated balance sheets for which the carrying value approximates fair value. See Note 10 - Assets and Liabilities Associated with Assets Held for Sale.
