Collateral Positions

The Company pledges securities or cash as collateral to its counterparties pursuant to its borrowings under repurchase agreements and its derivative contracts that are in an unrealized loss position, and it receives securities or cash as collateral pursuant to financing provided under reverse repurchase agreements and certain of its derivative contracts in an unrealized gain position. The Company exchanges collateral with its counterparties based on changes in the fair value, notional amount and term of the associated repurchase and reverse repurchase agreements and derivative contracts, as applicable. Through this margining process, either the Company or its counterparty may be required to pledge cash or securities as collateral. In addition, Swaps novated to and cleared by a central clearing house are subject to initial margin requirements. When the Company’s pledged collateral exceeds the required margin, the Company may initiate a reverse margin call, at which time the counterparty may either return the excess collateral, or provide collateral to the Company in the form of cash or high-quality securities.

The following table summarizes the fair value of the Company’s collateral positions, which includes collateral pledged and collateral held, with respect to its borrowings under repurchase agreements, reverse repurchase agreements and derivative hedging instruments at December 31, 2014 and 2013:
