Deposited and Pledged Securities The fair value of securities on deposit with various regulatory authorities was $10 million and $11 million as of December 31, 2012 and 2011, respectively. These deposits are required to comply with state insurance laws. The Company enters into securities borrowing and lending contracts in connection with MBIA’s collateralized investment agreement activities. Such contracts are only transacted with high-quality dealer firms. It is the Company’s policy to take possession of securities borrowed under these contracts. The Company minimizes credit risk from counterparties that might be unable to fulfill their contractual obligations by monitoring customer credit exposure and collateral values and requiring additional collateral to be deposited with the Company when deemed necessary. Substantially all of the obligations under investment agreements require the Company to pledge securities as collateral. Securities pledged in connection with investment agreement activities may not be repledged by the investment agreement counterparty. As of December 31, 2012 and 2011, the fair value of securities pledged as collateral for these investment agreements approximated $820 million and $1.9 billion, respectively. The Company’s collateral as of December 31, 2012 consisted principally of RMBS, U.S. Treasury and government agency bonds and state and municipal bonds, and was primarily held with major U.S. banks. Additionally, the Company pledged cash and money market securities as collateral under investment agreements in the amount of $144 million and $224 million as of December 31, 2012 and 2011, respectively.

Gross unrealized losses on AFS decreased as of December 31, 2012 compared with 2011 primarily due to the sale of impaired securities included in the Company’s asset/liability products segment and the sale of other securities that were impaired in 2012. Gross unrealized losses on HTM securities decreased as of December 31, 2012 compared with 2011 primarily due to market price appreciation. With the weighting applied on the fair value of each security relative to the total fair value, the weighted average contractual maturity of securities in an unrealized loss position as of December 31, 2012 and 2011 was 23 and 21 years, respectively. As of December 31, 2012 and 2011, there were 153 and 290 securities, respectively, that were in an unrealized loss position for a continuous twelve-month period or longer, of which the fair value of 89 and 218 securities, respectively, was below book value by more than 5%. The following table presents the distribution of securities by percentage of fair value below book value by more than 5%:

The following table presents the fair values and gross unrealized losses by credit rating category of ABS, MBS and corporate obligations included in the Company’s consolidated AFS investment portfolio as of December 31, 2012 for which fair value was less than amortized cost. The credit ratings are based on ratings from Moody’s as of December 31, 2012 or an alternate ratings source, such as S&P, when a security is not rated by Moody’s. For investments that are insured by various third-party guarantee insurers, the credit rating reflects the higher of the insurer’s rating or the underlying bond’s rating.

Refer to the table within the “Determination of Credit Loss Guaranteed by the Company and Other Third-Party Guarantors” section for information on the insured securities included in the preceding table. The Company concluded that it does not have the intent to sell securities in an unrealized loss position and it is more likely than not, that it would not have to sell these securities before recovery of their cost basis. In making this conclusion, the Company examined the cash flow projections for its investment portfolios, the potential sources and uses of cash in its businesses, and the cash resources available to its business other than sales of securities. It also considered the existence of any risk management or other plans as of December 31, 2012 that would require the sale of impaired securities. Impaired securities that the Company intends to sell before the expected recovery of such securities’ fair values have been written down to fair value. Other-Than-Temporary Impairments Evaluating AFS Securities for OTTI The Company has an ongoing review process for all securities in its investment portfolio, including a quarterly assessment of OTTI. This evaluation includes both qualitative and quantitative considerations. In assessing whether a decline in value is related to a credit loss, the Company considers several factors, including but not limited to (i) the magnitude and duration of declines in fair value; (ii) the reasons for the declines in fair value, such as general credit spread movements in each asset-backed sector, transaction-specific changes in credit spreads, credit rating downgrades, modeled defaults, and principal and interest payment priorities within each investment structure; and (iii) any guarantees associated with a security such as those provided by financial guarantee insurance companies, including MBIA Corp. and National. In calculating credit-related losses, the Company utilizes cash flow modeling based on the type of security. The Company’s cash flow analysis considers all sources of cash, including credit enhancement, that support the payment of amounts owed by an issuer of a security. This includes the consideration of cash expected to be provided by financial guarantors, including MBIA Corp., resulting from an actual or potential insurance policy claim. In general, any change in the amount and/or timing of cash flows received or expected to be received, whether or not such cash flows are contractually defined, is reflected in the Company’s cash flow analysis for purposes of assessing an OTTI loss on an impaired security. Each quarter, an internal committee, comprising staff that is independent of the Company’s evaluation process for determining OTTI of securities, reviews and approves the valuation of investments. Among other responsibilities, this committee ensures that the Company’s process for identifying and calculating OTTI, including the use of models and assumptions, is reasonable and complies with the Company’s internal policy. Determination of Credit Loss on ABS, MBS and Corporate Obligations Investments with unrealized losses that met the above criteria were tested for OTTI and principally related to ABS, MBS and corporate obligations. ABS investments are evaluated for OTTI using historical collateral performance, deal waterfall and structural protections, credit ratings, and forward looking projections of collateral performance based on business and economic conditions specific to each collateral type and risk. The underlying collateral is evaluated to identify any specific performance concerns, and stress scenarios are considered in forecasting ultimate returns of principal. Based on this evaluation, if a principal default is projected for a security, estimated future cash flows are discounted at the security’s interest rate used to recognize interest income on the security. For CDO investments, the Company utilizes the same tools as for RMBS investments discussed below, aggregating the bond level cash flows to the CDO investment level. If the present value of cash flows is less than the Company’s amortized cost for the security, the difference is recorded as an OTTI loss. RMBS investments are evaluated for OTTI using several quantitative tools. Loan level data is obtained and analyzed in a model that produces prepayment, default, and severity vectors. The model utilizes macro inputs, including housing price assumptions and interest rates. The vector outputs are used as inputs to a third-party cash flow model, which considers deal waterfall dynamics and structural features, to generate cash flows for an RMBS investment. The expected cash flows of the security are then discounted at the interest rate used to recognize interest income of the security to arrive at a present value amount. If the present value of the cash flows is less than the Company’s amortized cost for the investment, the difference is recorded as an OTTI loss. Corporate obligation investments are evaluated for OTTI using credit analysis techniques. The Company’s analysis includes a detailed review of a number of quantitative and qualitative factors impacting the value of an individual security. These factors include the interest rate of the security (fixed or floating), the security’s current market spread, any collateral supporting the security, the security’s position in the issuer’s capital structure, and credit rating upgrades or downgrades. Additionally, these factors include an assessment of various issuer-related credit metrics including market capitalization, earnings, cash flow, capitalization, interest coverage, leverage, liquidity, management and a third-party quantitative default probability model. The Company’s analysis is augmented by comparing market prices for similar securities of other issuers in the same sector, as well as any recent corporate or government actions that may impact the ultimate return of principal. If the Company determines that, after considering these factors, a principal default is projected, a recovery analysis is performed using the above data. If the Company’s estimated recovery value for the security is less than its amortized cost, the difference is recorded as an OTTI loss. For the years ended December 31, 2012, 2011 and 2010, the credit losses recognized in earnings were related to RMBS and CDOs. The following table presents a summary of the significant inputs considered in determining the measurement of the credit losses on securities in which a portion of the impairment is included in AOCI:

(1)—Represents future expected credit losses on impaired assets expressed as a percentage of total outstanding balance. (2)—Represents the range of inputs/assumptions based upon the individual securities within each category. (3)—Calculated by weighting the relevant input/assumption for each individual security by the outstanding notional of the security. (4)—Represents current level of credit protection (subordination) for the securities, expressed as a percentage of the balance of the collateral group backing the bond. (5)—Values represent high and low points of lifetime vectors of constant prepayment rates. Determination of Credit Loss Guaranteed by the Company and Other Third-Party Guarantors The Company does not record OTTI related to credit concerns about issuers of securities insured by MBIA Corp. and National since investors in these securities, including MBIA, are guaranteed payment of principal and interest when due by MBIA. Securities insured by the Company, whether or not owned by the Company, are evaluated for impairment as part of its insurance surveillance process and, therefore, losses on securities insured by the Company are recorded in accordance with its loss reserving policy. Refer to “Note 2: Significant Accounting Policies” for information about the Company’s loss reserving policy and “Note 6: Loss and Loss Adjustment Expense Reserves” for information about loss reserves. In considering cash expected to be provided from other third-party financial guarantors, the Company assesses the financial guarantor’s ability to make claim payments under a variety of scenarios that test the guarantor’s ultimate claims paying ability. The weighted average outcome of these scenarios, combined with the cash flows provided by the insured security, are used to determine the recoverability of the Company’s amortized cost. The following table provides information about securities held by the Company as of December 31, 2012 that were in an unrealized loss position and insured by a financial guarantor, along with the amount of insurance loss reserves corresponding to the par amount owned by the Company:

Credit Loss Rollforward The portion of certain OTTI losses on fixed-maturity securities that does not represent credit losses is recognized in AOCI. For these impairments, the net amount recognized in earnings represents the difference between the amortized cost of the security and the net present value of its projected future discounted cash flows prior to impairment. Any remaining difference between the fair value and amortized cost is recognized in AOCI. The following table presents the amount of credit loss impairments recognized in earnings on fixed-maturity securities held by MBIA as of the dates indicated, for which a portion of the OTTI losses was recognized in AOCI, and the corresponding changes in such amounts.
