Includes the effect of the contractual ability to settle contracts under master netting arrangements and margin cash collateral payments and receipts.  NEE also has 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)
At NEE, approximately $1,382 million ($1,244 million at FPL) are invested in commingled funds whose underlying investments would be Level 1 if those investments were held directly by NEE or FPL.

(a)
For the three months ended June 30, 2013, realized and unrealized gains of approximately $2 million are reflected in the condensed consolidated statements of income in operating revenues and $11 million in interest expense.  For the three months ended June 30, 2012, realized and unrealized gains of approximately $53 million are reflected in the condensed consolidated statements of income in operating revenues.
(b)
Transfers into Level 3 were a result of decreased observability of market data and, in 2013, the use of a significant credit valuation adjustment. 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 June 30, 2013, unrealized gains of less than $1 million are reflected in the condensed consolidated statements of income in operating revenues and approximately $11 million in interest expense.  For the three months ended June 30, 2012, unrealized gains of approximately $76 million are reflected in the condensed consolidated statements of income in operating revenues.
