The Corporation enters into sales of securities under agreements to repurchase. The amounts received under these agreements represent short-term borrowings and are reflected as a liability in the consolidated balance sheets. The securities underlying these agreements are included in investment securities in the consolidated balance sheets. The Corporation has no control over the market value of the securities, which fluctuates due to market conditions. However, the Corporation is obligated to promptly transfer additional securities if the market value of the securities falls below the repurchase agreement price. The Corporation manages this risk by maintaining an unpledged securities portfolio that it believes is sufficient to cover a decline in the market value of the securities sold under agreements to repurchase. Collateral pledged to repurchase agreements by remaining maturity are as follows:
