From a plan sponsor's perspective, risk deals mainly with whether
the plan will be able to meet its liability commitments or maintain
its surplus status. Factors which can influence this desired outcome
include market, exposure, currency and liquidity risk. How can a
plan sponsor correctly analyze and manage these risks? The key is
timely and accurate knowledge of the plan's investments at all times.
Purpose of Risk Management
The purpose of a good risk management program is twofold: to ensure
that risks are recognized and understood, and to compensate a plan
sponsor for assuming certain risks. A sponsor needs to ensure that
the risks the plan is exposed to are those that are intended. When
analyzed and properly managed, risk can be an integral part of achieving
the objectives of a plan.
Traditionally, institutional investors have allocated the lion's
share of their analytical and technology budgets towards making
money, with little or no resources devoted to minimizing the potential
of losing money. Risk management systems have too often been viewed
as a costly control function with little or no benefit to the bottom
line.1
Pension plans can manage risk in several ways. The simplest method
is to develop guidelines to identify specific risks which could
jeopardize the plan's objectives, then institute proper supervision
of investment policies. According to risk consultant Christopher
Culp of CP Partners in Chicago, "A proper risk management program
should complement, not replace the investment strategy put in place
by the plan sponsor, but should be able to measure, monitor and
manage the risk of an investment portfolio. Risk measurement involves
quantifying the risks faced by investors. The measurement system
should examine all risks that the plan is currently exposed to relative
to the risks of a target benchmark. Although risk resides at the
individual security level, it is important to look at summary risk
measures." 2
Measuring Risk
To manage risk, you must be able to measure it. As information technology
and financial modeling capabilities converge, plan sponsors have
a profusion of new risk measurement tools at their disposal, including
Value at Risk (VaR).
Until recently, limited tools were available to a plan sponsor
who wanted to aggregate market risk across all portfolios and asset
classes. Sponsors need answers to questions such as:
* What do you do if your equity portfolio's beta exceeds its risk
threshold or the duration on the fixed income portfolio is longer
than that of the benchmark?
*Which portfolio is riskier?
* How do you compare risk or aggregate risk across portfolios?Standard
deviation has some usefulness, but since the measurement is historical
in nature and only shows the past behaviour of the portfolio, it
does not warn whether a fund has suddenly changed its risk profile.
Unless risk can be measured it cannot be managed!
That's why certain plans looked towards VaR methodologies to see
if VaR could be used to manage their pension fund's risk. Why Use
VaR?
VaR is gaining increased acceptance as a measure of plan-wide risk.
VaR is an attractive measure for plan sponsors for many reasons.
It is an easy number to understand and explain to the board of trustees.
It is also useful for monitoring and controlling risk within the
fund. Lastly, VaR allows risks across different types of securities
to be aggregated and represented using a common denominator.
Everyone can understand risk when it is explained in dollar terms.
A portfolio that has a $1 million VaR with a 95% confidence interval
would expect to lose no more than $1 million, only 5% of the time.
VaR is an exhaustive measure of market risk and one that can be
aggregated at all levels, by manager to the total fund level. You
can't simply add up risk measures such as beta, duration and standard
deviation to get a complete measure of risk. VaR allows you to do
just that.
VaR is also useful for monitoring and controlling risk within the
fund. As a monitoring tool, VaR draws attention to large swings
in risk caused by the purchase of risky financial instruments and/or
excessive concentration in securities, sectors or countries. The
use of this tool helps the plan sponsor evaluate the effectiveness
of managers or investment strategies by providing a consistent methodology
for estimating risk over time, relative to the overall market.
Sponsors can also use VaR to develop risk budgets for managers.
Managers are assigned a dollar amount of risk, and must manage their
portfolios within this prescribed amount. A red flag goes up when
a security is purchased that places the fund above its stated risk
threshold. The benefits of this approach are twofold: the sponsor
no longer needs to approve every transaction, and managers are able
to be evaluated on a risk-adjusted basis.
The sponsor must ensure that the benefits of implementing a VaR
system do not exceed the cost. In order to decide which model is
most appropriate, it is important to understand not only the intricacy
of the models, but how the plan intends to use the information provided
by a VaR system. The complexity of the needs will often dictate
the model, and hence the cost of a VaR system.
Another factor affecting implementation is how often the VaR is
calculated. The purpose of VaR is to identify risk, so the more
frequently the tool is used, the better equipped a manager will
be to manage risk when it arises.
Despite the benefits VaR provides, it is not the 'be-all and end-all'
for risk worried plan sponsors. VaR is simply one tool in the risk
manager's toolbox. VaR will not prevent, or even forewarn a plan
sponsor of market crashes or sudden changes in interest rates. It
does, however, allow the plan sponsor to establish a particular
risk target and monitor whether the fund has exceeded the threshold
or desired risk level. It also ensures that the risks the sponsor
believes and wants the plan to be exposed to are the same as the
actual risks of the plan.
Exposure Analysis
Investment managers have long accepted the notion that diversification
is necessary to eliminate unsystematic risk in an investment portfolio.
However, many sponsors ignore this basic tenet when looking at their
entire plan. Although each manager may share specific concentration
and diversification guidelines, often ignored is the aggregate exposure
to risk when each manager's contribution to the mix is taken into
account.
Detailed exposure reporting is key to any risk management program.
As plan sponsors continue the trend of sub-contracting the investment
management function to external advisors, there is a risk that the
individual holdings within the externally managed accounts will
overlap, thus exposing the fund to unwanted concentration in particular
issues, sectors and markets. For this reason, it is vitally important
to look through a plan's individual holdings and aggregate exposures
to different markets, sectors, and issues to ensure that the plan
is achieving the full benefits of diversification.
Style Analysis
Style management has gained considerable acceptance within the plan
sponsor community. By taking a disciplined style offset approach,
a fund can carefully select a variety of investment styles that
will help the plan meet its performance objectives during different
cycles in the market. The problem with this approach is that managers
do not always stay true to their style, particularly when it falls
out of favour. This imposes a risk to the sponsor, since the plan
may be overexposed to a certain style in the market. Some pension
funds are intensifying their monitoring of how closely active managers
are adhering to their stated investment styles, as well as how the
manager styles interact with one another, thus allowing for better
risk control and diversification. The sponsor can manage the total
risk of the portfolio simply by monitoring their managers more closely.
Although the process of managing managers can vary from one sponsor
to another, an effective review of investment managers generally
requires access to technology, fundamental style characteristics
and a listing of portfolio holdings. Portfolio information, linked
to a database of analytical characteristics and technology provides
a consistent means of analyzing this information on a regular basis.
Alternative Risk Measures
Although alternative risk measures have gained acceptance in the
pension plan world, most of them are used primarily by consultants.
New measures in risk/return analysis allow plan sponsors to analyze
the return per unit of risk in order to ensure that certain investment
advisors are not placing the fund's assets at any undue risk.
In their simplest form, alternative risk measures can offer insight
into which investment advisor has demonstrated superior risk adjusted
performance relative to a benchmark. By using more complicated risk
measures one can examine downside risk volatility, in order to capture
the probability of achieving negative performance. "You can't
really separate risk analysis from performance analysis. If a manager
is making a large return, obviously he or she is taking on some
kind of risk to gain those returns," according to Desmond MacIntyre,
director of risk management for General Motors Investment Management
Corporation.3
Among the measures available to help ascertain plan risk, plan
sponsors consider downside, variance and beta to be the most important.
Downside risk captures the uncertainty of not achieving one's goals;
variance captures the risk of not achieving the average return;
and beta captures the risk of being in the market.4 While the greater
number of ways used to measure risk the better, no risk management
program should omit the consideration of these three key measures.
Additional measures, such as information ratios and Sortino ratios,
will also allow the sponsor to examine the value added by investment
strategies, on a risk-adjusted basis.
Conclusion
The practice of risk management is a multifaceted, elaborate process,
involving large amounts of information and analysis. However, the
complexity of the process need not discourage a plan sponsor. The
risk management process is purely a function of measuring, monitoring
and overseeing risk. As long as plan sponsors commit themselves
to this process, they can identify and measure the risks to which
they are exposed, thus beginning the process of eliminating unwanted
risk. A variety of risk measurements are available to choose from.
The important thing to remember is that measurement in itself is
not the solution...rather it is the systematic process of identifying,
monitoring and reviewing risk.
