The fair value and the cost or amortized cost of fixed maturity investments, at March 31, 2012, by contractual maturity, are shown below.  Actual maturities may ultimately differ from contractual maturities because borrowers have, in some cases, the right to call or prepay obligations with or without call or prepayment penalties. Pre-refunded municipal bonds are classified based on their pre-refunded call dates.
