We estimated the fair value of each class of financial instruments, for which estimating fair value is practicable, by applying the following methods and assumptions:

Cash and cash equivalents—The carrying amount of cash and cash equivalents represents the historical cost, plus accrued interest, which approximates fair value because of the short maturities of those instruments.  We measured the estimated fair value of our cash equivalents using significant other observable inputs, representative of a Level 2 fair value measurement, including the net asset values of the investments.  At June 30, 2017 and December 31, 2016, the aggregate carrying amount of our cash equivalents was $2.1 billion and $2.6 billion, respectively.

Restricted cash—The carrying amount of the cash and cash equivalents that are subject to restrictions due to collateral requirements, legislation, regulation or court order approximates fair value due to the short term nature of the instruments in which the restricted cash balances are held.  At June 30, 2017, the aggregate carrying amount of such restricted cash and cash equivalents was $486 million, including $461 million and $25 million recorded in current assets and other long‑term assets, respectively.  At December 31, 2016, the aggregate carrying amount of such restricted cash and cash equivalents was $387 million, including $352 million and $35 million recorded in current assets and other long‑term assets, respectively.

The carrying amount of the restricted cash investments pledged for debt service of the Eksportfinans Loans and for security of certain other credit arrangements represents the amortized historical cost of the investment.  We measured the estimated fair value of such restricted cash investments using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads of the instruments.  At June 30, 2017 and December 31, 2016, the aggregate carrying amount of the restricted cash investments was $76 million and $123 million, respectively.  At June 30, 2017 and December 31, 2016, the estimated fair value of such restricted cash investments was $77 million and $124 million, respectively.

Debt—We measured the estimated fair value of our debt, all of which was fixed‑rate debt, using significant other observable inputs, representative of a Level 2 fair value measurement, including the terms and credit spreads for the instruments.
