Ambac Shares Dive After Steep Loss, the Washington Post reports:
"The company's shares fell 19 percent pre-market as Ambac reiterated that it is writing "very little new business," and that the weak quarter wiped out 40 percent of the company's net worth."
"The quarterly loss was $1.66 billion, or $11.69 a share, compared with year-earlier net income of $213.3 million, or $2.02 a share. Excluding items, Ambac's loss was $6.93 per share, far more than analysts' average forecast for a loss of $1.82 a share and a sharp reversal from year-earlier earnings of $2 a share."
"The company said it marked down the value of derivatives on repackaged mortgage bonds, known as collateralized debt obligations, by $940.4 million, because it expects to make payouts on those securities. Total mark-to-market losses on credit derivatives were $1.7 billion."
"Net premiums written sagged 38 percent to $135.7 million."
"The results were weak enough to erase $980 million, or 40 percent, of Ambac's shareholders' equity. The company struggled to sell $1.5 billion of shares and convertible securities in March as New York State Insurance Superintendent Eric Dinallo worked with banks and others to help the insurer raise capital."
Was this really such a surprise for the market? Why does Moody's and S&P still support their credit rating?
"Many investors can only hold bonds with "triple-A" ratings from both Moody's and S&P. Fitch stripped Ambac Assurance of its top ratings in January. Callen said on Wednesday that the company exceeds S&P's target capital level by a comfortable margin, and expects to exceed Moody's target level in the second quarter."
The above statement about investors being restricted to only holding triple-A rated bonds addresses why Moody's and S&P have been reluctant to downgrade this wounded duck. If they do, then it will completely wipe out Ambac's creditability, and therefore its ability to generate new business, spark a wave of selling, lowering prices and will fuel more inevitable write-downs in our financial institutions. These predictions of exceeding capital requirements by years end just do not seem fathomable to me. If you're looking for a brief introduction to how bond insurers got themselves in this mess the consult
The Legend of Subprime. Back in November of 2007, Pershing released a paper
How to Save the Bond Insurers which addresses how bond insurers business operates, their problems, and possible solutions. For now, I will skip over the basic operations and economics of bond insurers and analyze exposures and risks:
"Bond Insurers will likely soon need to fund significant claims. In our view, their capital resources are grossly insufficient to meet these demands


Applying Merrill Lynch and Citigroup valuations to guarantors’ Super Senior CDO exposure would eliminate 45%-107% of their statutory capital"
Specifically for Ambac, Fitch in the Pershing paper estimates they are under capitalized by $459 million, while MBIA will have excess cushion of over $3 billion. These are only 4Q projections and Pershing warns of more expected losses from sub-prime exposure well into 2008.
"Bond Insurer CDO of ABS MTM losses are less than 1/10th the ~20% write- downs taken by banks"

Since the majority of CDO problems are the consequences of sub-prime and alt-A loans that should have never been approved by underwriters in a bubble housing market, foreclosures will continue to rise, possibly well into 2010 as ARM resets occur, check out the estimates in the chart on the left provided by Deutsche Bank. The model assumes 30% default rates based on ARM resets, predicting home foreclosures will persist into 2010. This is only the start of the problem for the bond insurers, now enter home equity lines of credit HELOC) and closed end second mortgates (CES).
"Home Equity Lines of Credit (HELOC) and Closed-end Second Mortgages (CES) securitizations are junior to even the most subordinated tranches of a typical Mezzanine CDO"
"Bond Insurers typically insure HELOCs and CES to the underlying BBB level. HELOCs and CES are in a first-loss position and are leveraged to a decline in housing values"
"In a flat to declining home price environment, we believe HELOCs and CES are likely to suffer 100% loss severity upon default"
Applying Mortgage Insurers’ own loss estimates to MBIA and Ambac’s exposure implies large losses which have not been reserved for
In essence, MBIA and Ambac are uncapitalized or only mildly capitalized for losses in the ABS market, but have no reserves for HELOC's and CES's in which defaults will prove more severe because they are junior to other higher tranche mortgages. Combined, the two bond insurers have a total estimate in losses for HELOC's and CES's of approximately $13.5 billion. Thought you were now out of the woods...think again! The above was in reference to Reisidential Mortgage Backed Securities (RMBS), but take a look back into
The Real Estate Epic Turns Another Page and learn that commercial real estate and Commercial Real Estate Backed Securities (CMBS) will be in just as much trouble as the residential side.
"CMBX spread movement suggests potentially significant impairment in the underlying CMBS securities insured by MBIA"
This is not the end of the line here for exposure risks, also included is the reinsurance exposure and below investment grade exposure. Adding those into the formula estimate losses now total to $8,791 for MBIA and $8,020 for Ambac:

The list continues, as even the bond insurers investment portfolios are questioned as overvalued, but there is no estimate of losses. Liquidity risks are now apparent, and with downgrades come higher capital requirements. Considerably more leverage is being carried, with MBIA's debt to equity at almost 5.
"Approximately $5.5 billion of MBIA’s on-balance-sheet debt will come due before year-end 2008, $8.5 billion before year-end 2009"
Uncovered here, there are still many more considerations in the suspect business of the bond insurers. The bond insurers are doomed. Rating agencies will eventually be forced to downgrade them, capital will be difficult, if possible at all to raise any more, and undesirable worthless securities will liquidate at bargain prices....finally bankruptcy.
