[1] Outstanding and unallocated shares held by the Employee Stock Ownership Plan (ESOP) Trust totaled approximately 3 million, 4 million and 5 million at December 31, 2012, 2011 and 2010, respectively; the original number of shares purchased and held by the ESOP Trust was approximately 25 million shares.

[2] The sum of the quarterly amounts may not equal the total for the year due to rounding.

[3] In the opinion of NEE and FPL, all adjustments, which consist of normal recurring accruals necessary to present a fair statement of the amounts shown for such periods, have been made. Results of operations for an interim period generally will not give a true indication of results for the year.
