Why Toxic Assets Are So Hard to Clean Up

Despite trillions of dollars of new government programs, one of the original
causes of the financial crisis -- the toxic assets on bank balance sheets --
still persists and remains a serious impediment to economic recovery. Why
are these toxic assets so difficult to deal with? We believe their sheer
complexity is the core problem and that only increased transparency will
unleash the market mechanisms needed to clean them up.

The bulk of toxic assets are based on residential mortgage-backed securities
(RMBS), in which thousands of mortgages were gathered into mortgage pools.
The returns on these pools were then sliced into a hierarchy of "tranches"
that were sold to investors as separate classes of securities. The most
senior tranches, rated AAA, received the lowest returns, and then they went
down the line to lower ratings and finally to the unrated "equity" tranches
at the bottom.

But the process didn't stop there. Some of the tranches from one mortgage
pool were combined with tranches from other mortgage pools, resulting in
Collateralized Mortgage Obligations (CMO). Other tranches were combined with
tranches from completely different types of pools, based on commercial
mortgages, auto loans, student loans, credit card receivables, small
business loans, and even corporate loans that had been combined into
Collateralized Loan Obligations (CLO). The result was a highly heterogeneous
mixture of debt securities called Collateralized Debt Obligations (CDO). The
tranches of the CDOs could then be combined with other CDOs, resulting in
CDO2.

Each time these tranches were mixed together with other tranches in a new
pool, the securities became more complex. Assume a hypothetical CDO2 held
100 CLOs, each holding 250 corporate loans -- then we would need information
on 25,000 underlying loans to determine the value of the security. But
assume the CDO2 held 100 CDOs each holding 100 RMBS comprising a mere 2,000
mortgages -- the number now rises to 20 million!

Complexity is not the only problem. Many of the underlying mortgages were
highly risky, involving little or no down payments and initial rates so low
they could never amortize the loan. About 80% of the $2.5 trillion subprime
mortgages made since 2000 went into securitization pools. When the housing
bubble burst and house prices started declining, borrowers began to default,
the lower tranches were hit with losses, and higher tranches became more
risky and declined in value.

To better understand the magnitude of the problem and to find solutions, we
examined the details of several CDOs using data obtained from SecondMarket,
a firm specializing in illiquid assets. One example is a $1 billion CDO2
created by a large bank in 2005. It had 173 investments in tranches issued
by other pools: 130 CDOs, and also 43 CLOs each composed of hundreds of
corporate loans. It issued $975 million of four AAA tranches, and three
subordinate tranches of $55 million. The AAA tranches were bought by banks
and the subordinate tranches mostly by hedge funds.

Two of the 173 investments held by this CDO2 were in tranches from another
billion-dollar CDO -- created by another bank earlier in 2005 -- which was
composed mainly of 155 MBS tranches and 40 CDOs. Two of these 155 MBS
tranches were from a $1 billion RMBS pool created in 2004 by a large
investment bank, composed of almost 7,000 mortgage loans (90% subprime).
That RMBS issued $865 million of AAA notes, about half of which were
purchased by Fannie Mae and Freddie Mac and the rest by a variety of banks,
insurance companies, pension funds and money managers. About 1,800 of the
7,000 mortgages still remain in the pool, with a current delinquency rate of
about 20%.

With so much complexity, and uncertainty about future performance, it is not
surprising that the securities are difficult to price and that trading dried
up. Without market prices, valuation on the books of banks is suspect and
counterparties are reluctant to deal with each other.

The policy response to this problem has been circuitous. The Federal Reserve
originally saw the problem as a lack of liquidity in the banking system, and
beginning in late 2007 flooded the market with liquidity through new lending
facilities. It had very limited success, as banks were still disinclined to
buy or trade such securities or take them as collateral. Credit spreads
remained higher than normal. In September 2008 credit spreads skyrocketed
and credit markets froze. By then it was clear that the problem was not
liquidity, but rather the insolvency risks of counterparties with large
holdings of toxic assets on their books.

The federal government then decided to buy the toxic assets. The Troubled
Asset Relief Program (TARP) was enacted in October 2008 with $700 billion in
funding. But that was not how the TARP funds were used. The Treasury
concluded that the valuation problem seemed insurmountable, so it attacked
the risk issue by bolstering bank capital, buying preferred stock.

But those toxic assets are still there. The latest disposal scheme is the
Public-Private Investment Program (PPIP). The concept is that private asset
managers would create investment funds of half private and half Treasury
(TARP) capital, which would bid on packages of toxic assets that banks
offered for sale. The responsibility for valuation is thus shifted to the
private sector. But the pricing difficulty remains and this program too may
amount to little.

The fundamental problem has remained untouched: insufficient information to
permit estimated prices that both buyers and sellers find credible. Why is
the information so hard to obtain? While the original MBS pools were often
Securities and Exchange Commission (SEC) registered public offerings with
considerable detail, CDOs were sold in private placements with
confidentiality agreements. Moreover, the nature of the securitization
process has made it extremely difficult to determine and follow losses and
increasing risk from one tranche and pool to another, and to reach the
information about the original borrowers that is needed to estimate future
cash flows and price.

This account makes it clear why transparency is so important. To deal with
the problem, issuers of asset-backed securities should provide extensive
detail in a uniform format about the composition of the original pools and
their subsequent structure and performance, whether they were sold as
SEC-registered offerings or private placements. By creating a centralized
database with this information, the pricing process for the toxic assets
becomes possible. Making such a database a reality will restart private
securitization markets and will do more for the recovery of the economy than
yet another redesign of administrative agency structures. If issuers are not
forthcoming, then they should be required to file the information publicly
with the SEC.
