There remains considerable uncertainty as to future developments in the European debt crisis and the impact on financial markets.

RMBS have a gross unrealized loss greater than twelve months of $6.5 million as of June 30, 2013. Factors such as the credit enhancement within the deal structure, the average life of the securities, and the performance of the underlying collateral support the recoverability of these investments.

The other asset-backed securities have a gross unrealized loss greater than twelve months of $31.9 million as of June 30, 2013. This category predominately includes student-loan backed auction rate securities, the underlying collateral, of which is at least 97% guaranteed by the Federal Family Education Loan Program (“FFELP”). These unrealized losses have occurred within the Company’s auction rate securities (“ARS”) portfolio since the market collapse during 2008. At this time, the Company has no reason to believe that the U.S. Department of Education would not honor the FFELP guarantee, if it were necessary.

The corporate bonds category has gross unrealized losses less than and greater than twelve months of $273.0 million and $21.3 million, respectively, as of June 30, 2013. These declines were primarily related to changes in interest rates during the period. The aggregate decline in market value of these securities was deemed temporary due to positive factors supporting the recoverability of the respective investments. Positive factors considered include credit ratings, the financial health of the issuer, the continued access of the issuer to capital markets, and other pertinent information.

The equities category has a gross unrealized loss greater than twelve months of $6.9 million as of June 30, 2013. The aggregate decline in market value of these securities was deemed temporary due to factors supporting the recoverability of the respective investments. Positive factors include credit ratings, the financial health of the issuer, the continued access of the issuer to the capital markets, and other pertinent information.

The Company does not consider these unrealized loss positions to be other-than-temporary, based on the factors discussed and because the Company has the ability and intent to hold these investments until the fair values recover, and does not intend to sell or expect to be required to sell the securities before recovering the Company’s amortized cost of debt securities.

RMBS had a gross unrealized loss greater than twelve months of $9.8 million as of December 31, 2012. The non-agency RMBS market experienced improvements during the year, but these losses represented securities where credit concerns were more pronounced. Factors such as the credit enhancement within the deal structure, the average life of the securities, and the performance of the underlying collateral support the recoverability of these investments.

The other asset-backed securities had a gross unrealized loss greater than twelve months of $33.2 million as of December 31, 2012. This category predominately includes student-loan backed auction rate securities, the underlying collateral, of which is at least 97% guaranteed by the FFELP. These unrealized losses have occurred within the Company’s ARS portfolio since the market collapse during 2008. At this time, the Company has no reason to believe that the U.S. Department of Education would not honor the FFELP guarantee, if it were necessary.

The corporate bonds category had gross unrealized losses greater than twelve months of $24.8 million as of December 31, 2012. The aggregate decline in market value of these securities was deemed temporary due to positive factors supporting the recoverability of the respective investments. Positive factors considered include credit ratings, the financial health of the issuer, the continued access of the issuer to capital markets, and other pertinent information.

The equities category had a gross unrealized loss greater than twelve months of $4.8 million as of December 31, 2012. The aggregate decline in market value of these securities was deemed temporary due to factors supporting the recoverability of the respective investments. Positive factors include credit ratings, the financial health of the issuer, the continued access of the issuer to the capital markets, and other pertinent information.

As of June 30, 2013, the Company had securities in its available-for-sale portfolio which were rated below investment grade of $1.4 billion and had an amortized cost of $1.4 billion. In addition, included in the Company’s trading portfolio, the Company held $356.5 million of securities which were rated below investment grade. Approximately $422.3 million of the below investment grade securities were not publicly traded.

The change in unrealized gains (losses), net of income tax, on fixed maturity and equity securities, classified as available-for-sale is summarized as follows:

	For The						For The
	Three Months Ended						Six Months Ended

Variable Interest Entities

The Company holds certain investments in entities in which its ownership interests could possibly be considered variable interests under Topic 810 of the FASB ASC (excluding debt and equity securities held as trading, available-for-sale, or held-to-maturity). The Company reviews the characteristics of each of these applicable entities and compares those characteristics to applicable criteria to determine whether the entity is a Variable Interest Entity (“VIE”). If the entity is determined to be a VIE, the Company then performs a detailed review to determine whether the interest would be considered a variable interest under the guidance. The Company then performs a qualitative review of all variable interests with the entity and determines whether the Company is the primary beneficiary. ASC 810 provides that an entity is the primary beneficiary of a VIE if the entity has 1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and 2) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE.

Based on this analysis, the Company had an interest in one wholly owned subsidiary, Red Mountain, LLC (“Red Mountain”), that continued to be classified as a VIE as of June 30, 2013. The activity most significant to Red Mountain is the issuance of a note in connection with a financing transaction involving Golden Gate V Vermont Captive Insurance Company (“Golden Gate V”) and the Company in which Golden Gate V issued non-recourse funding obligations to Red Mountain and Red Mountain issued the note to Golden Gate V. Credit enhancement on the Red Mountain Note is provided by an unrelated third party. For details of this transaction, see Note 6, Debt and Other Obligations. The Company had the power, via its 100% ownership through an affiliate, to direct the activities of the VIE, but did not have the obligation to absorb losses related to the primary risks or sources of variability to the VIE. The variability of loss would be borne primarily by the third party in its function as provider of credit enhancement on the Red Mountain Note. Accordingly, it was determined that the Company is not the primary beneficiary of the VIE. The Company’s risk of loss related to the VIE is limited to its investment of $10,000. Additionally, PLC has guaranteed the VIE’s payment obligation for the credit enhancement fee to the unrelated third party provider.
