Valuing Financial Institutions: Integrating Internal and External
Metrics
This talk focuses on the challenges of linking the metrics typically
used by financial institutions to measure performance (e.g. RAROC, economic
capital, etc.) and the metrics by which the firms are valued in the
market (e.g. P/E, P/B multiples). Providing a clear link between these
metrics is important for ensuring that the way that performance is evaluated
internally is in alignment with the way that markets value the firm.
Using a combination of empirical evidence and theory, we investigate
the role of economic capital, returns, cost of capital, earnings volatility
and growth on firm valuation.
Focusing especially on the appropriate cost of capital for financial
services, we argue that many financial institutions significantly and
systematically overvalue their investment banking and other higher systematic
risk businesses and undervalue their retail banking, personal lines
insurance and other low risk businesses. As a direct consequence, many
institutions are defining and implementing corporate strategies that
destroy shareholder value by unknowingly subsidising higher risk with
lower risk activities. Recent theoretical research and empirical results
indicate that this issue has substantial implications in terms of corporate
strategy. In the article to be discussed, we take the theory to its
logical conclusion and use cross-section and time series data to answer
three important questions:
First, is there empirical evidence that shareholders require different
hurdle rates for different businesses, even if each business is capitalised
to a common rating standard? We will call this the 'Differentiated Cost
of Capital Effect'. This effect has strong implications for evaluating
the relative performance of individual business lines that reside under
a common corporate rating umbrella.
Second, is there empirical evidence that, all else being equal, shareholders
require a premium from firms that have increased leverage, and therefore
probability of default, for a comparable risk/return? We call this the
'Leverage or Default Effect'. This effect has strong implications for
corporate capitalisation and the rationalisation of the shareholder-
and debtholder perspectives.
Third, is there empirical evidence that, all else being equal, shareholders
place a premium on firms that have less idiosyncratic risk and can therefore
afford greater leverage? We call this the 'Idiosyncratic Risk Cost'.
This effect has potentially strong implications on corporate strategy
and portfolio diversification.

Multiple Points of Failure: A New View on Risk Management
We discuss the notion of risk management as a managerial science and
its incorporation into the business decision-making process. Brittle
systems break badly. In other words, when they fail the consequences
can be catastrophic. While the tail is comprised of catastrophic events,
risk managers are charged with both determining sufficient capital levels
to survive highly unlikely events and helping businesses to maximize
the return on desired risk. Focus on using risk management to create
ductile systems, ones that fail well, addresses both of these issues.
In many cases, these systems lower the need for risk capital and also
reduce the frequency of high-impact events. Building on lessons from
network security experts and other concepts of risk management, risk
managers can do more of a job to educate and disseminate information
than most realize. Quantitative rigor is enhanced through qualitative
implementation. If risk management is to avoid the fate of accountancy,
it must become an integral part of a process rather than simply a function
delivering reports.
