At each reporting date, the Company reviews its investments to determine whether a decline in fair value below the amortized cost basis is other than temporary. To determine whether a decline in value is other than temporary, the Company evaluates several factors including the nature of the securities held, credit rating or financial condition of the issuers, the extent and duration of the unrealized losses, prevailing market conditions, and whether the Company will more likely than not be required to sell the impaired securities before the amortized cost basis is fully recovered. The Company determined that no other-than-temporary impairment exists for the years ended December 31, 2012, 2011 and 2010.
