[1] Transfers into and out of Level 3 during the years ended December 31, 2013 and 2012 were attributable to changes in the availability of observable market information for individual fixed maturity securities. The Company’s policy is to recognize transfers into and transfers out of the levels as having occurred at the end of the reporting period in which the transfers were determined.
