Reclassification Out Of Accumulated Other Comprehensive Income [Table Text Block]
Unrealized gains or losses related to available-for-sale securities are recorded in accumulated other comprehensive income ("AOCI"). When securities are sold and a realized gain or loss is recognized, the amount is reclassified from AOCI to the income statement. For the three and six months ended June 30, 2013 and 2012, the amounts of net realized gains recognized in the income statement for the sale of investments were as follows (in thousands):
