Cash management accounts represent retail accounts with customers for which the Bank has pledged certain assets as collateral.

Trustco Bank also has an available line of credit with the Federal Home Loan Bank of New York which approximates the balance of securities pledged against such borrowings.  The line of credit requires securities to be pledged as collateral for the amount borrowed. As of December 31, 2011 and 2010, the Company had no outstanding borrowings with the Federal Home Loan Bank of New York and, as a result, there were no related securities pledged.
