Schedule of Credit Derivatives

Written credit derivatives held by the Company at December 31, 2014 and 2013, are summarized below:

Credit Derivatives	Amount at December 31, 2014			Amount at December 31, 2013
(In thousands)
Fair Value of Written Credit Derivatives, Net	$	27,741		$	1,421
Fair Value of Purchased Credit Derivatives Offsetting Written Credit Derivatives with Third Parties (1)	$	(3,287	)	$	57
Notional Amount of Written Credit Derivatives (2)	$	(341,014	)	$	(120,497	)
Notional Amount of Purchased Credit Derivatives Offsetting Written Credit Derivatives with Third Parties (1)	$	54,874		$	249

(1) Offsetting transactions with third parties include purchased credit derivatives which have the same reference obligation.

(2) The notional value is the maximum amount that a seller of credit protection would be obligated to pay, and a buyer of credit protection would receive upon occurrence of a "credit event." Movements in the value of credit default swap transactions may require the Company or the counterparty to post or receive collateral. Amounts due or owed under credit derivative contracts with an International Swaps and Derivatives Association, or "ISDA," counterparty may be offset against amounts due or owed on other credit derivative contracts with the same ISDA counterparty. As a result, the notional amount of written credit derivatives involving a particular underlying reference asset or index has been reduced (but not below zero) by the notional amount of any contracts where the Company has purchased credit protection on the same reference asset or index with the same ISDA counterparty.
