The carrying value of securities pledged as collateral to secure public deposits and for other purposes was $52.1 million and $55.7 million at September 30, 2011 and March 31, 2011, respectively.
 
Certain investments in debt securities are reported in the financial statements at an amount less than their historical cost.  The total fair value of these investments at September 30, 2011 and March 31, 2011, was $13.4 million and $28.6 million, which represented approximately 10% and 22%, respectively, of the Company's aggregate available-for-sale and held-to-maturity investment portfolio.  These declines resulted primarily from changes in market interest rates.
 
Based on evaluation of available evidence, including recent changes in market interest rates, credit rating information and information obtained from regulatory filings, management believes the declines in fair value for these government agency, mortgage-backed and state and political subdivision securities are temporary at September 30, 2011.
 
Should the impairment of any of these government agency, mortgage-backed and state and political subdivision securities become other than temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the other-than-temporary impairment is identified.  The following table shows the Company's investments' gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position.
