Risk Management for
Managers
Lalit Sharma & Deepak Choudhury
Much of what managers need to know about modern risk
management falls under four general headings: general risk management,
the use of derivatives, value at risk and related issues, and dealing
with taxation and regulation.
1. On General Risk Management
-
Make sure you know the business and the
risks it entails.
-
Remember that you are the risk manager.
You should have a clear corporate policy on risk that is understood by
everyone concerned. You should also have some idea of the risks your
firm is taking and why.
-
The objective of risk management is not to
eliminate or even minimise risks, but to manage them appropriately,
considering the potential benefits from risk-taking.
-
Risk management is a form of engineering:
it uses science, but ultimately depends on judgement.
-
The ultimate protection against risk is
good judgement and alertness.
-
Observe what goes on elsewhere and learn
from the mistakes of others. If similar problems occur in your firm,
prevent them.
-
It is particularly important to learn from
others when they lose huge amounts of money or go bankrupt. See that
your firm is covered.
-
When firms get into major difficulties,
the problems involved are usually ones that management thought they
had taken care of.
-
It is the operational risks that usually
bring institutions down. Remember Barings.
-
The best defences against operational
risks are sound systems of management control and vigilant managers.
-
Be on the look-out for the obvious -
business units that are apparently earning very large profits for no
clear reason, figures in reports that are clearly suspicious, sudden
deteriorations in performance, other managers under severe stress,
very high turnover of staff, and that sort of thing.
-
If you are tempted to regard risk
management as expensive, think of the alternative. Don’t regard risk
management as a drain on profits.
-
Get good people you can trust, pay them
well and back their judgement. Good people are far more valuable than
good systems.
-
Talk to your risk management people and be
aware of their concerns.
-
Take some interest in stress testing and
contingency planning exercises.
-
Never think that a fancy risk management
system takes care of your risks for you and thereby relieves you of
the need to stay alert.
-
Understand the limitations of your risk
management systems. Be clear about the risks your systems do not cover
well, especially operational ones. Ask what could go wrong, ask
yourself if the results seem right, and so forth.
-
Have your risk management systems
occasionally checked over by outside experts, and listen to their
advice. Listen to your auditors as well.
-
Remember that risk management is not an
exact science, so do not be fooled by spuriously precise answers or be
impressed by people who talk in such terms.
-
Policy statements should give substantial
objectives and policy guidelines, as opposed to the meaningless
platitudes that abound in modern corporate life.
2. Dealing with Derivatives
-
Do not be put off by the use of
derivatives in recent problems. Derivatives are very useful tools,
when used properly.
-
Remember that derivatives have one or more
of three uses: to take a position (i.e., to speculate), to hedge, or
to reduce funding costs. If you are thinking about using derivatives,
be clear why.
-
Derivatives can therefore increase or
decrease the overall risks, depending on how they are used.
-
Be aware of the leverage (i.e., the
potential for gains or losses) in your derivatives positions,
particularly leverage that might be hidden in complex derivatives
positions.
-
If you are using derivatives to reduce
funding costs, make sure you understand why/how the contract gives you
lower funding costs. In particular, make sure that you have not agreed
to hidden options or other contingent payoff clauses that could lead
to large losses later on.
-
When dealing with derivatives providers,
recognise that they always know more than you do.
-
When considering contracts with
derivatives providers, satisfy yourself that you broadly understand
the risks you are thinking of taking on.
-
When considering any derivatives contract,
satisfy yourself that you want to take on the risks involved.
-
Don’t forget that people sometimes make
very silly mistakes, especially when dealing with derivatives.
-
In assessing a derivatives contract,
particularly a complex one, have the contract reverse-engineered into
its basic building block components - this helps in understanding the
risks involved - and consider whether you would be better off taking
on the building blocks instead.
-
Shop around for quotes from different
derivatives providers before agreeing to a particular contract.
-
Protect yourself against unscrupulous
providers by seeking qualified second opinions.
-
You can also protect yourself by asking
questions and insisting on full written answers. Questions should
focus on prospective losses for different realisations of the
underlying risk variable(s) (i.e., scenario analyses).
-
If the answers you get are incomplete,
unclear or otherwise unsatisfactory, don’t get involved in long-drawn
out negotiations. Just assume the worst and take your business
elsewhere.
-
If you are not sure what questions to ask,
seek guidance from your own risk managers or outside consultants.
Always check with them anyway before signing anything.
-
Know your exit costs. When negotiating
with providers, try to nail down your likely liquidation costs in
advance by asking for written quotes that specify the terms on which
they would unwind your derivatives positions later.
-
Before finally agreeing to any contract,
decide on your stop loss position, so you know in advance the maximum
loss you will tolerate before bailing out. Ensure that everyone else
involved also knows the stop loss position.
-
Having established your stop loss
strategy, keep to it.
-
When dealing with outside consultants,
deal with people you can trust. As a general rule, employ consultants
who have no axe to grind because they are not trying to sell you their
own systems.
3. Dealing with VaR and Associated Systems
-
Do not regard the VaR movement as just
another management fad that will go away if you ignore it. VaR is not
like business process re-engineering. It is here to stay and you may
as well get used to it.
-
There are some very good reasons to take
the VaR movement seriously. It has a lot to offer.
-
Understand clearly what the terms VaR, ERM,
CFaR and the like actually mean. More important still, understand what
they don’t mean (i.e., understand that VaR does not give the maximum
possible loss, and so on).
-
Try to get some feel for what these VaR,
ERM and other systems involve - their strengths, their potential uses,
their limitations and weaknesses, and the like. This does not mean
that you have to become an expert on them.
-
You should investigate what benefits these
various systems - VaR systems, ERM systems, CFaR systems, etc. - could
bring to your particular firm. However, also recognise that the
benefits can vary a lot from one firm to another, depending on each
firm’s particular business and circumstances.
-
If you decide to adopt any of these
systems, be clear why. There is only one good reason: you should adopt
them if and because they fit your business needs, as you have
identified them.
-
Don’t adopt VaR and associated systems
just because your competitors are doing so. Resist the temptation to
behave like a lemming.
-
Don’t adopt them just because you have
some vague idea that they will help you steal a march on the
competition. You are unlikely steal a march on the competition if you
don’t know what you are doing.
-
Don’t adopt them in response to pressure
from shareholders or systems providers. Shareholders pay you to make
these decisions for them and systems providers are looking for
business.
-
Pay attention to what other firms are
doing, and learn from them.
-
Don’t be hurried, and remember that there
is always the option of wait and see. Waiting allows you to see what
mistakes other firms make so you can avoid them. Waiting till later
will also be cheaper, because costs will fall over time.
-
Think carefully (and seek advice) about
the level of technology that is adequate for you.
-
Establish the level of technology that is
adequate to your needs - historical simulation, variance-covariance,
or Monte Carlo simulation.
-
The systems with the lowest level of
technology are historical simulation ones, the highest tech ones are
Monte Carlo systems, and variance-covariance systems are somewhere
between.
-
As a general rule, you are best off
adopting the system with the lowest adequate level of technology. The
higher the level of technology, the greater the expense, the more
difficult the system is to use, and the greater the chances of
something going badly wrong.
-
Don’t ever buy a complex system without
satisfying yourself that you really need it - don’t buy an expensive
Monte Carlo system, say, when a simple historical simulation system
would do.
-
Be discriminating - systems must suit your
particular business needs. Remember that there is even more variety
(and potential variety) among CFaR and ERM systems than among VaR
systems proper.
-
As a general rule, large firms need
systems fitted for them, as opposed to systems just bought off the
shelf and imported without much thought. This is particularly so when
it comes to ERM and CFaR systems.
-
Be wary of buying expensive systems off
the shelf, and be very wary of providers who would sell you very
complex systems that only rocket scientists can understand.
-
Shop around for systems and service
providers, and don’t confuse expense with quality. It is very easy to
spend a lot of money on a poor or inappropriate system.
-
Never, ever, buy complex systems that
no-one in your firm is comfortable with. Either the systems are
unnecessarily complex or else you need to hire people who can work
with them.
-
Make sure you have access to advice from
people who understand the area. Work closely with your risk management
and treasury people, and don’t go against their advice unless you have
good reason to.
-
When setting up VaR and related systems,
ensure that you also develop good stress testing capability. Make sure
that you use these systems in conjunction with regular and detailed
stress tests.
-
Take some interest in stress testing
exercises, if only to inform the broader planning process.
-
You should insist that your VaR, CFaR,
stress test and other reports be informative, but not unnecessarily
so. They should be short and to the point, and written in plain
language. Besides reporting key numbers, they should also warn you of
important problems or qualifications that you should be aware of.
-
Insist on periodic longer reports that go
into more detail and keep you warned of medium to longer term problems
and other issues that would not make it into your more regular VaR
reports.
-
Keep in mind that no systems ever give
guaranteed results. Remember the more general risk management rules
set out earlier. Never think that you have some foolproof system that
allows you to go to sleep. Never be complacent.
4. Dealing with Taxation and Regulation
4.1. Dealing with Taxation
-
Be clear about the difference between
avoidance (which is legal) and evasion (which is not). Remember:
evasion is what you must avoid.
-
The interests of your stakeholders require
you to avoid (as opposed to evade) taxation as best you can. To do
anything else is to give their money away.
-
Remember that your primary and, indeed,
overriding, responsibilities are to your stakeholders, not to the
regulators, the tax authorities or their political masters. It is your
duty to avoid taxation.
-
You should insist that your firm puts some
serious effort into avoidance.
-
Avoidance is often best done discretely.
-
The more complex the tax system, the more
loopholes it has, and the more opportunities there are for avoidance.
Remember also that there are all sorts of differences between tax
systems across different countries and sectors. Exploit these to the
full.
-
In avoiding tax, you need people who
understand the rules, and the people who usually understand them best
are tax officials themselves. You should therefore consider hiring
some of the game-keepers to poach for you.
-
Tax specialists can save you a lot of
money. You should therefore be willing to pay them well. This also
helps give you the edge over the tax authorities, since they can
seldom match private-sector salaries.
4.2.
Dealing with Financial Regulation
-
Work from the premise that regulation as
such is a nuisance. You either follow a particular regulatory rule
because it embodies good practice for your firm, which you would
therefore want follow anyway, or else you want to avoid it.
-
You
therefore need to distinguish between ‘good’ rules that you want to
follow and ‘bad’ ones that you don’t.
-
A good rule is one that is compatible with
or promotes your firm’s interest, broadly defined. The firm’s interest
is not just the maximisation of profits, but also encompasses the
firm’s (and your) various statutory, ethical and other obligations to
the people you are dealing with.
-
Examples of good rules
would be rules of good business practice, useful disclosure rules in
financial statements, certain rules specifying your obligations to
employees and customers, and the like.
-
You have to make the distinction between
good and bad rules. You do so by deciding which rules are good. The
rest can then be regarded as bad.
-
You should regard the bad rules as a form
of taxation. They are therefore to be avoided.
-
Avoidance of bad regulatory rules is
similar in many respects to tax avoidance. The same points therefore
apply - you have a duty to avoid them, you should hire specialists,
exploit loopholes, be discrete, and so forth.
-
Keep in mind that regulation by and large
does not work. If a regulation stops you doing what you want to do,
you can usually find some way to get round it or at least to mitigate
its impact.
