Financial institutions have “risk
managers,” whose job is, in essence, to worry about such matters as we’ve been
discussing. A risk manager assesses the risk to an institution’s portfolio or
portfolios, assigns the appropriate number, and (to the extent his organization
allows) does generally try to mitigate it. Speaking a bit roughly, there are
four things to do about any given risk: avoid it, mitigate it, transfer it,
retain it.
If a risk manager persuades his
superiors that a particular proposed merger comes with a lot of risk, because a
“due diligence” review shows the potential target company has a lot of off-balance-sheet
liabilities, then he may scuttle the merger entirely. Mission accomplished.
If he can’t scuttle the merger, he
can at least suggest ways in which the risks of the merger may be reduced, by
for example making it a condition of any deal that the target entity spin off
its more troublesome subsidiaries first.
When it can be neither avoided nor
reduced, risk can often be transferred. If you’re worried that you own a
flammable piece of property, you buy fire insurance. This doesn’t eliminate or
even reduce the chance of fire, but it makes that chance somebody else’s
problem.
Finally, the default choice is that
the identified risk is simply retained.
One obvious problem with this job
description: the risk manager doesn’t himself make any readily discernible
contribution to the bottom line, certainly not in quarter-by-quarter terms.
Indeed, in a boom period the risk manager may well lessen the bottom line by
virtue of doing his job well.
One sign of a bubble is that the
services of risk managers are devalued. They lose the nice corner office and
end up in a broom closet. This was John Breit’s situation at Merrill Lynch in
2007.
Breit (pictured above) the head of “market risk”
at Merrill. At the peak of his prominence in the councils of Mother Merrill, in
2002, he reported directly to the company’s CFO and could also as needed
communicate directly with the board of directors. The board, in turn,
understood that Breit was intimately familiar with the particulars of their
complex derivatives positions. His analyses carried weight.
But by 2006, people weren’t even
bothering to be polite to old wet-blanket Breit anymore. This was a pity,
because the company was becoming ever more dependent on the sorts of
instruments he understood at least as well as anyone around. Key examples were
collateralized debt obligations (pools of non-mortgage but securitized debt)
and even CDOs Squared (pools of the pools of non-mortgage debt).
In August 2007, Dale Lattanzio, the
head of Merrill’s operations with CDOs pressured two junior analysts to sign off
on a new piece of accounting trickery that would let Lattanzio and in turn
those to whom he had to report take a more optimistic view of the value of the
CDOs on Merrill’s balance sheet.
The two pressured quants reported
Lattanzio’s approach to Breit. This startled Breit into a thorough inquiry into
Lattanzio’s operations, and he soon discovered that the CDO operation stood to
cost Merrill not the mere millions that Lattanzio was admitted were at risk,
but billions.
There was $55 billion worth of exposure,
and $40 billion of that had been added just in the preceding year, since Breit
had been in effect consigned to the broom closet.
Is there any further reading you would recommend on this?
