Gross realized gains from the sale or maturity of available-for-sale investments were zero during the three months ended March 31, 2012. Gross realized gains from the sale or maturity of available-for-sale investments were minimal during the three months ended March 31, 2011. The Company did not record losses on investments experiencing an other-than-temporary decline in fair value nor did it record any gross realized losses from the sale or maturity of available-for-sale investments during the three months ended March 31, 2012 and 2011.
