MBIA Inc. Reports Fourth Quarter and Full Year 2010 Financial Results

Highlights

• MBIA Inc.’s Adjusted Book Value (ABV), a non-GAAP measure, was $36.81 per share at December 31, 2010 compared with $37.22 per share at September 30, 2010 and $38.94 at December 31, 2009.
• MBIA Inc. recorded net income available to common shareholders of $451 million, or $2.24 per share, for the fourth quarter of 2010, compared with a net loss of $240 million, or $1.16 per share, in the fourth quarter of 2009.
• MBIA Inc.’s adjusted pre-tax loss, a non-GAAP measure, was $311 million in the fourth quarter of 2010 compared with an adjusted pre-tax loss of $541 million in the fourth quarter of 2009.
• During the fourth quarter of 2010, MBIA Insurance Corp. (MBIA Corp.) reached agreements with five counterparties for commutations of transactions including multi-sector CDOs, multi-sector CDO-squareds, structured CMBS pools, commercial real estate CDOs and high-yield corporate CDOs. The agreements eliminated $15.7 billion in gross insured exposure in exchange for one-time payments by MBIA Corp. that were consistent with its aggregate statutory loss reserve for these transactions.

ARMONK, N.Y.--(BUSINESS WIRE)--March 1, 2011--MBIA Inc. (NYSE: MBI) (the Company) today reported Adjusted Book Value (ABV) per share (a non-GAAP measure defined in the attached Explanation of Non-GAAP Financial Measures) of $36.81 as of December 31, 2010, compared with $37.22 as of September 30, 2010. During the fourth quarter, the Company modified its calculation of ABV as described in the attached Explanation of Non-GAAP Financial Measures. Book value per share was $14.18 as of December 31, 2010.

Net income available to common shareholders for the fourth quarter of 2010 was $451 million, or $2.24 per share, compared with a net loss of $240 million, or $1.16 per share, in the fourth quarter of 2009. Net income in the fourth quarter of 2010 was driven primarily by a $1.1 billion pre-tax unrealized net gain on the fair value of insured derivatives resulting primarily from the reversal of the mark-to-market on commuted transactions.

The adjusted pre-tax loss, a non-GAAP measure (defined in the attached Explanation of Non-GAAP Financial Measures), for the fourth quarter of 2010 was $311 million compared with an adjusted pre-tax loss of $541 million in the fourth quarter of 2009. The Company believes that ABV and adjusted pre-tax income provide investors with additional views of its operating results that management finds useful in measuring financial performance.

“The fourth quarter and full year 2010 represented the thirteenth quarter and fourth year, respectively, in which our company’s results reflected the impact of having insured securitizations primarily consisting of ineligible mortgages,” said MBIA Inc. President and Chief Financial Officer Chuck Chaplin. “Since 2007, we have paid $9.1 billion in gross claims on mortgage securitizations, CDOs and other transactions, demonstrating the value of bond insurance to investors. Investors in uninsured securities in the same general asset classes have sustained substantial cash losses, while those who hold securities wrapped by MBIA Corp. and National Public Finance Guarantee Corp. haven’t suffered a single dollar of loss. This fact provides simple and obvious evidence for the value in uncertain times of the bond insurance we provided. Meanwhile, our insurance companies continue to have adequate resources to meet all expected future claims obligations,” Mr. Chaplin continued. “The commutations and terminations of $15.7 billion of exposure in the fourth quarter improved the balance sheet position of MBIA Corp. and eliminated the volatility associated with the commuted policies, while National has been steadily improving its capital position.

“Importantly, we recently won dismissal of one of the lawsuits challenging the separation of MBIA Corp. and National,” said Mr. Chaplin. “Although the decision is being appealed, we remain confident that in all of the cases challenging our Transformation, the courts will find that the New York State Insurance Department acted properly and within its authority in approving the separation of our companies.”

Full Year 2010 Results

MBIA Inc.’s Adjusted Book Value (ABV) per share was $36.81 as of December 31, 2010, compared with $38.94 as of December 31, 2009. Net income available to common shareholders for the full year 2010 was $53 million, or $0.26 per share, compared with net income of $623 million, or $2.99 per share, for the full year 2009. Net income in 2010 was impacted primarily by a $607 million pre-tax unrealized net loss on the fair value of insured derivatives resulting primarily from a change in the market perception of MBIA Corp.’s credit risk. By contrast, in 2009 the Company recorded a $1.7 billion pre-tax unrealized net gain on the fair value of insured derivatives. The adjusted pre-tax loss for the full year 2010 was $377 million compared with an adjusted pre-tax loss of $877 million in 2009. The adjusted pre-tax loss in 2010 declined relative to 2009 primarily due to lower net investment losses related to other-than-temporary impairments and lower losses on insured exposures.

Fourth Quarter 2010 Segment Results

The following is a summary of book value and ABV per share data as of December 31, 2010 and pre-tax results by segment for the fourth quarter:

U.S. Public Finance Results

The Company’s U.S. public finance insurance business is conducted through its National Public Finance Guarantee Corp. (National) subsidiary. National recorded $103 million of adjusted pre-tax income in the fourth quarter of 2010 compared with $186 million of adjusted pre-tax income in the fourth quarter of 2009. Lower adjusted pre-tax income in the fourth quarter of 2010 resulted from increased loss and loss adjustment expenses as well as declines in premiums earned, fees and reimbursements and net investment income. Despite positive pre-tax income, National’s book value declined in the quarter due to a $138 million unrealized loss on investments recorded directly in Other Comprehensive Income (OCI).

National's insured portfolio generated total premiums earned of $112 million in the fourth quarter of 2010 compared with $137 million in total premiums earned in the fourth quarter of 2009.

Net investment income for National declined 17 percent to $54 million in the fourth quarter of 2010 from $65 million in the comparable period of 2009 due to lower average yields. Over the same period, National’s investment portfolio increased in size by 4 percent, from $5.3 billion at December 31, 2009 to $5.5 billion at December 31, 2010. National’s investment portfolio remains liquid, averaging Double-A credit quality.

National’s loss and loss adjustment expenses totaled $31 million in the fourth quarter, compared with $2 million in the fourth quarter of 2009. Loss and loss adjustment expenses in the fourth quarter of 2010 were driven primarily by a transaction backed by a not-for-profit entity.

National’s amortization of deferred acquisition costs totaled $23 million in the fourth quarter of 2010, down 12 percent from $26 million in the fourth quarter of 2009, reflecting slower amortization and fewer refundings within its insured portfolio in the fourth quarter of 2010 compared with the fourth quarter of 2009. Operating expenses were $17 million in the fourth quarter of 2010, down 11 percent from $19 million in the comparable period of 2009.

As of December 31, 2010, National’s statutory capital was $2.4 billion and its claims-paying resources totaled $5.6 billion.

Structured Finance and International Insurance Results

The Structured Finance and International Insurance business is conducted through MBIA Corp. and its subsidiaries.

The adjusted pre-tax loss for the Structured Finance and International Insurance segment for the fourth quarter of 2010 was $487 million compared with an adjusted pre-tax loss of $766 million in the fourth quarter of 2009. Premiums earned, net investment income, fees and reimbursements, and premiums and fees on insured derivatives totaled $167 million in the fourth quarter of 2010. Losses, credit impairments (a non-GAAP measure defined in the attached Explanation of Non-GAAP Financial Measures) and loss-related expenses on insured exposures totaled $563 million in the fourth quarter while operating expenses and all other line items in the aggregate had a net $91 million negative impact on the adjusted pre-tax loss.

During the fourth quarter of 2010, the Company increased its expectations for losses on insured exposures in the Structured Finance and International Insurance segment. The following is a summary of all insured portfolio economic loss activity in the fourth quarter. Economic losses for a reporting period represent the change in the Company’s estimate of the present value of expected net future claims payments without regard to the manner in which they are presented in the Company’s financial statements.

In the fourth quarter, the Company increased its expectations of future losses on RMBS exposures. The Company increased its expectations of future claims payments by $458 million as early stage delinquencies in the underlying mortgage pools did not decline as anticipated during the quarter. However, this increase was partially offset by additional expected recoveries of $337 million, primarily from contractual claims related to ineligible mortgages. The Company’s estimates for expected recoveries related to “putbacks” of ineligible mortgages totaled $2.5 billion as of December 31, 2010. However, based on the Company’s assessment of the strength of its contract claims, the Company believes it is entitled to collect the full amount of its cumulative incurred losses, which totaled $4.4 billion as of December 31, 2010, from those securitization sponsors against whom it is pursuing litigation.

The Company reduced its estimate of economic losses on multi-sector ABS CDOs by $182 million in the fourth quarter, as previously established loss reserves and credit impairments on certain transactions commuted in the quarter exceeded the sum of cash payments made to counterparties in connection with the commutations and all other net adjustments to expected losses on such transactions.

In the fourth quarter of 2010, the Company estimated $604 million of incremental economic losses on certain insured transactions backed by pools of commercial mortgage-backed securities (CMBS). The increase was due to modest deterioration in the performance of the assets underlying these insured transactions and changes in modeling assumptions that resulted in an increase in modeled losses, even though there were relatively few property liquidations and only minor erosion in the deductibles of several pools.

The following is a summary of the $563 million in fourth quarter economic losses categorized on the basis of how they are reflected in the Company’s financial statements:

The $377 million of credit impairments and loss adjustment expenses on insured credit derivatives estimated by the Company in the fourth quarter of 2010 consisted of the previously mentioned $604 million of incremental economic losses on transactions backed by pools of commercial mortgage-backed securities offset by a reduction of approximately $227 million in economic losses on multi-sector ABS CDO transactions, primarily as a result of commutations during the quarter.

In the fourth quarter of 2010, MBIA Corp. paid a total of $290 million in net claims in connection with its second-lien residential mortgage exposures. Net claims on insured RMBS have been trending downward each quarter since peaking at $636 million in the second quarter of 2009.

During the fourth quarter, MBIA Corp. reached agreements with five counterparties for commutations of transactions including multi-sector CDOs, multi-sector CDO-squareds, structured CMBS pools, commercial real estate CDOs and high-yield corporate CDOs. The agreements eliminated $15.7 billion in gross insured exposure. In the first quarter of 2011, MBIA Corp. reached an agreement for the commutation of $3.3 billion of additional gross insured exposure, primarily comprising structured CMBS pools. Since the fourth quarter of 2008, the Company has commuted $28.0 billion of its multi-sector CDO, multi-sector CDO-squared, corporate CDO, CRE CDO and CMBS pool gross insured exposure for payments that were consistent with its aggregate statutory loss reserve for those transactions. The commutations significantly reduce the potential future volatility of the structured finance insured portfolio.

As of December 31, 2010, the Company’s net derivative liability (the cumulative negative mark-to-market) with respect to insured credit derivatives was $4.4 billion for all non-consolidated VIE insured credit derivatives. The Company considers approximately $2.4 billion of the $4.4 billion net derivative liability to be credit impaired. The Company expects the unimpaired portion of the unrealized gains and losses in fair value (marks-to-market) to be reversed prior to or upon the maturities of the insured credit derivatives.

As of December 31, 2010, MBIA Corp.’s statutory balance sheet reflected $3.3 billion in cash and invested assets including $524 million of cash and short-term investments. Cash, short-term investments and other highly liquid investments available to meet liquidity demands totaled $1.2 billion as of December 31, 2010, excluding amounts held by subsidiaries. The Company believes that MBIA Corp.’s liquidity resources will adequately provide for anticipated cash outflows.

MBIA Corp. had statutory capital of $2.7 billion and claims-paying resources totaling $5.2 billion at December 31, 2010.

Advisory Services

The Company’s Advisory Services business is conducted in its Cutwater Asset Management subsidiaries. Cutwater recorded a pre-tax loss of $3 million in the fourth quarter driven by expenses associated with infrastructure enhancements to support its growth plans.

Cutwater’s average assets under management in the fourth quarter were $41.6 billion, down 4 percent from $43.2 billion in the third quarter of 2010 reflecting seasonality in its local government investment pools business and lower balances managed for MBIA Inc. and its subsidiaries. Average assets under management in the fourth quarter comprised $25.4 billion from third-party clients and $16.2 billion managed for MBIA Inc. and its subsidiaries. Third-party average assets under management decreased 4 percent from the third quarter of 2010 and increased 2 percent from the fourth quarter of 2009. For the full year 2010, third-party average assets under management increased 10 percent from 2009.

Corporate Segment

The Corporate segment comprises MBIA Inc.’s holding company activities and certain subsidiaries, including Optinuity Alliance Resources Corp.

The Corporate segment recorded pre-tax income of $34 million in the fourth quarter of 2010 compared with pre-tax income of $35 million in the fourth quarter of 2009. Pre-tax income in the fourth quarters of 2010 and 2009 was driven by positive marks-to-market on outstanding warrants issued on MBIA Inc. common stock.

As of December 31, 2010, the Corporate segment had $358 million in cash and short-term investments.

During the fourth quarter of 2010, the Corporate segment converted the $600 million inter-segment loan it made to the Asset Liability Products segment within Wind-Down Operations in the fourth quarter of 2008 to a capital contribution in settlement of the full outstanding principal balance of the loan. The conversion enhances the liquidity position of the Asset Liability Products segment.

The Company did not repurchase any of its common stock during the fourth quarter. As of December 31, 2010, approximately $73 million of repurchase authorization remained available under the Company's $1.0 billion share buyback program.

Wind-Down Operations

Wind-Down Operations comprise the Company’s Asset Liability Management and Conduit businesses, both of which are in run-off.

Pre-tax income for Wind-Down Operations was $42 million in the fourth quarter of 2010 compared with pre-tax income of $5 million in the fourth quarter of 2009. Pre-tax income in the fourth quarter of 2010 was driven by a $62 million net gain on financial instruments at fair value and foreign exchange resulting primarily from increased values of interest rate swaps not designated as hedges.

This segment repurchased $24 million par amount of medium-term notes at discounts during the fourth quarter, resulting in net gains on the extinguishment of debt that totaled $8 million.

Explanation of Non-GAAP Financial Measures

The following are explanations of why MBIA believes that the non-GAAP financial measures used in this press release, which serve to supplement GAAP information, are meaningful to investors.

Adjusted Book Value: Adjusted Book Value (“ABV”), a non-GAAP measure, is used by the Company to supplement its analysis of GAAP book value. The Company uses ABV as a measure of fundamental value and considers the change in ABV an important measure of periodic financial performance. ABV adjusts GAAP book value to remove the impact of certain items which the Company believes will reverse over time, as well as to add in the impact of certain items which the Company believes will be realized in GAAP book value in future periods. The Company has limited such adjustments to those items that it deems to be important to fundamental value and performance and which the likelihood and amount can be reasonably estimated. ABV assumes no new business activity. The Company has presented ABV to allow investors and analysts to evaluate the Company using the same measure that MBIA’s management regularly uses to measure financial performance. ABV is not a substitute for and should not be viewed in isolation from GAAP book value.

In the fourth quarter of 2010, after completing a review of the components of ABV, the Company removed the Wind-Down Operations future spread adjustment and the loss provision adjustment. The Wind-Down Operations future spread adjustment adjusted book value to reflect the net present value of asset and liability cash flows within the Company’s Wind-Down Operations assuming that the cash flow profile of the business would remain constant to maturity. The Company believes this adjustment is no longer meaningful in its analysis of the performance and value of the Company as it intends to actively manage the run-off of its wind-down operations, resulting in uncertain future cash flows. The loss provision adjustment to book value represented a formulaic estimate of potential future losses based on the Company’s practice prior to 2009 of recording a general loss reserve for unidentified claims based on 12 percent of net earned premium. While current U.S. GAAP no longer permits such a reserve, the Company maintained this concept in the calculation of ABV to account for a potential level of unknown loss development in future periods. The Company believes this adjustment is no longer meaningful in light of current GAAP for financial guarantee insurance contracts, which requires probability-weighted loss reserves based on all possible outcomes across our entire financial guarantee insurance portfolio, our practice of calculating and including in ABV credit impairments on insured credit derivatives, and the considerable volatility in the Company’s losses over the last several years.

ABV is calculated on a consolidated basis and a segment basis. ABV by segment provides information about each segment’s contribution to consolidated ABV and is calculated using the same formula.

ABV per share represents that amount of ABV allocated to each common share outstanding at the measurement date.

Credit Impairments on Insured Derivatives: Credit impairments on insured derivatives represent the present value of the Company’s estimate of expected future claim payments for such transactions, using a discount rate required by statutory accounting principles. Since the Company’s insured credit derivatives have similar terms, conditions, risks, and economic profiles to its financial guarantee insurance policies, the Company evaluates them for impairment periodically in the same way that it estimates loss and LAE for its financial guarantee insurance policies. Credit impairments on insured derivatives are equal to the Company’s statutory losses for such contracts.

Credit impairments on insured derivatives may differ from the fair values recorded in the Company’s financial statements. The Company expects that the majority of its exposure written in derivative form will not be settled at fair value. The fair value of an insured derivative contract will be influenced by a variety of market and transaction-specific factors that may be unrelated to potential future claim payments. In the absence of credit impairments or the termination of derivatives at losses, the cumulative unrealized losses recorded from fair valuing insured derivatives should reverse before or at the maturity of the contracts. Contracts also may be settled prior to maturity at amounts that may be more or less than their recorded fair values. Those settlements can result in realized gains or losses, and the reversal of unrealized losses. For these reasons, the Company believes its disclosure of credit impairments on insured derivatives provides additional meaningful information to investors about potential realized losses on these contracts.

Adjusted Pre-tax Income: Adjusted pre-tax income, a non-GAAP measure, is used by the Company to supplement its analysis of GAAP pre-tax income. The Company uses adjusted pre-tax income as a measure of fundamental periodic financial performance. Adjusted pre-tax income adjusts GAAP pre-tax income to remove the effects of consolidating insured VIEs and gains and losses related to fair valuing insured credit derivatives, which the Company believes will reverse over time, and adds in changes in the present value of insurance claims the Company expects to pay on insured credit derivatives based on its ongoing insurance loss monitoring.
