_______________

(1)At September 30, 2012 and December 31, 2011, insurance-linked securities include a longevity swap for which the notional amount is not reflective of the overall potential exposure of the swap. As such, the Company has included the probable maximum loss under the swap within the net notional exposure as an approximation of the notional amount.

(2)The Company enters into interest rate swaps to mitigate notional exposures oncertain total return swaps. Accordingly, the notional valueof interest rate swaps is not presented separately in the table.
