The collateral utilized for the Company’s repurchase agreements is subject to market fluctuations as well as prepayments of principal. The Company monitors the risk of the fair value of its pledged collateral falling below acceptable amounts based on the type of the underlying repurchase agreement. The pledged collateral related to the Company’s term wholesale repurchase agreement, which matures in 2018, is monitored on a monthly basis and additional capital is pledged when necessary. The pledged collateral related to the Company’s sweep repurchase agreements, which mature on a daily basis, is monitored on a daily basis as the underlying sweep accounts can have daily transaction activity and the amount of pledged collateral is adjusted as necessary.
