(a) Includes the effect of the contractual ability to settle contracts under master netting arrangements and the netting of margin cash collateral payments and receipts. NEE and FPL also have contract settlement receivable and payable balances that are subject to the master netting arrangements but are not offset within the condensed consolidated balance sheets and are recorded in customer receivables - net and accounts payable, respectively.

(b) Includes restricted cash of approximately $108 million ($30 million for FPL) in other current assets on the condensed consolidated balance sheets.

(c) Excludes investments accounted for under the equity method and loans not measured at fair value on a recurring basis. See Fair Value of Financial Instruments Recorded at the Carrying Amount below.

(d) Primarily invested in commingled funds whose underlying securities would be Level 1 if those securities were held directly by NEE or FPL.

(e) See Note 2 - Fair Value of Derivative Instruments for a reconciliation of net derivatives to NEE's and FPL's condensed consolidated balance sheets.

Significant unobservable inputs used in valuation of contracts categorized as Level 3

The significant unobservable inputs used in the valuation of NEE's commodity contracts categorized as Level 3 of the fair value hierarchy at March 31, 2016 are as follows:

Reconciliation of changes in the fair value measured based on significant unobservable inputs

The reconciliation of changes in the fair value of derivatives that are based on significant unobservable inputs is as follows:

	Three Months Ended March 31,
	2016						2015
	NEE			FPL			NEE			FPL
	(millions)
Fair value of net derivatives based on significant unobservable inputs at December 31 of prior year	$	538		$	—		$	622		$	5
Realized and unrealized gains (losses):
Included in earnings(a)	254			—			30			—
Included in other comprehensive income (loss)	(6		)	—			15			—
Included in regulatory assets and liabilities	(3		)	(3		)	(1		)	(1		)
Purchases	100			—			22			—
Settlements	(133		)	(5		)	(187		)	(5		)
Issuances	(74		)	—			(20		)	—
Transfers in(b)	3			—			(19		)	—
Transfers out(b)	(30		)	—			(11		)	—
Fair value of net derivatives based on significant unobservable inputs at March 31	$	649		$	(8	)	$	451		$	(1	)
The amount of gains (losses) for the period included in earnings attributable to the change in unrealized gains (losses) relating to derivatives still held at the reporting date(c)	$	196		$	—		$	38		$	—

————————————

(a) For the three months ended March 31, 2016 and 2015, realized and unrealized gains of approximately $274 million and $47 million, respectively, are reflected in the condensed consolidated statements of income in operating revenues and the balance is primarily reflected in interest expense.

(b) Transfers into Level 3 were a result of decreased observability of market data and transfers from Level 3 to Level 2 were a result of increased observability of market data. NEE's and FPL's policy is to recognize all transfers at the beginning of the reporting period.

(c) For the three months ended March 31, 2016 and 2015, unrealized gains of approximately $216 million and $55 million, respectively, are reflected in the condensed consolidated statements of income in operating revenues and the balance is reflected in interest expense.

Fair Value, by Balance Sheet Grouping

Fair Value of Financial Instruments Recorded at Other than Fair Value - The carrying amounts of cash equivalents, commercial paper and notes payable approximate their fair values. The carrying amounts and estimated fair values of other financial instruments recorded at other than fair value, are as follows:

	March 31, 2016						December 31, 2015
	Carrying Amount			Estimated Fair Value			Carrying Amount			Estimated Fair Value
	(millions)
NEE:
Special use funds(a)	$	653		$	653		$	675		$	675
Other investments - primarily notes receivable	$	517		$	770	(b)	$	512		$	722	(b)
Long-term debt, including current maturities	$	29,931	(c)	$	31,928	(d)	$	28,897	(c)	$	30,412	(d)
FPL:
Special use funds(a)	$	508		$	508		$	528		$	528
Long-term debt, including current maturities	$	9,990		$	11,509	(d)	$	10,020		$	11,028	(d)

————————————

(a) Primarily represents investments accounted for under the equity method and loans not measured at fair value on a recurring basis.

(b) Primarily classified as held to maturity. Fair values are primarily estimated using a discounted cash flow valuation technique based on certain observable yield curves and indices considering the credit profile of the borrower (Level 3). Notes receivable bear interest primarily at fixed rates and mature by 2029. Notes receivable are considered impaired and placed in non-accrual status when it becomes probable that all amounts due cannot be collected in accordance with the contractual terms of the agreement. The assessment to place notes receivable in non-accrual status considers various credit indicators, such as credit ratings and market-related information. As of March 31, 2016 and December 31, 2015, NEE had no notes receivable reported in non-accrual status.

(c) Excludes debt totaling $936 million and $938 million, respectively, reflected in liabilities associated with assets held for sale on NEE's condensed consolidated balance sheet for which the carrying amount approximates fair value. See Note 8 - Assets and Liabilities Associated with Assets Held for Sale.

(d) As of March 31, 2016 and December 31, 2015, for NEE, approximately $18,378 million and $18,031 million, respectively, is estimated using quoted market prices for the same or similar issues (Level 2); the balance is estimated using a discounted cash flow valuation technique, considering the current credit spread of the debtor (Level 3). For FPL, primarily estimated using quoted market prices for the same or similar issues (Level 2).
