[1] The following is a rollforward of the gross carrying amount and accumulated depreciation of other real estate for the years ended December 31, 2014 and 2013.

[3] None of the gains (losses) recorded in earnings during the periods is attributable to the change in unrealized gains (losses) relating to Level 3 assets still held at the reporting dates.
[4] These gains (losses) are recorded in the following line items in the consolidated statements of income: (See Schedule of gains losses on fair value of RE securities).
