nded December 31, 2010, gross transfers of $2 million into Level 3 were a result of decreased observability of market data, and gross transfers of $46 million from Level 3 to Level 2 were a result of increased observability of market data. NextEra Energy's and FPL's policy is to recognize all transfers at the beginning of the reporting period.7For the year ended December 31, 2010 and 2009, $153 million and $270 million, respectively, of unrealized gains are reflected in operating revenues in the consolidated statements of income.
