Financial Risk Management
Why does it matter?
 Why and when should we hedge?
 What should we hedge? How should we
gauge exposure?


Financial risk management must be tied
to the company’s business
Copyright ©1999 Ian H. Giddy
Financial Risk Management -6
The Case For Hedging
Company has special information
 Company has special market access
 Secure cash for investment opportunities
 Reduce potential costs of financial
distress, increase debt capacity, and
reduce expected taxes
Since currency matching reduces the
probability of financial distress, it allows
the firm to have greater leverage and
therefore a greater tax shield.

Which Firms Should Hedge?
Characteristics of firms for which financial stress is
especially costly:
 Firms with:
 Products
that require after-sale servicing
 Products whose quality is difficult to determine in
advance
 Products with high switching costs
 Products that rely on third-party servicing

And firms that have:
 High-growth
opportunities
 Intangible assets like firm-specific human capital
 Large excess tax deductions

Formalize Risk Management Policy and
Control Framework
• Develop an outline of a policy
statement, or recommend
improvements to existing
document
• Benchmark controls versus best
practice using the Group of
Thirty Recommendations,

accumulated knowledge of
appropriate practices

Identification and Definition of
Financial Exposures
Goal: To identify significant financial risk exposures and
prioritize them in a manner consistent with
management's desired risk profile.

exposure
• Intracompany versus third
party exposure
• Cross currency exposure

Exposure
Transactions exposure results from
particular transactions such as an export
where a known cash flow in a given
currency will take place at a certain date
Example:
If Nokia invoices a NTT of Japan in
Japanese yen for a celphone shipment then
the firm has Japanese yen exposure and can
hedge this by borrowing yen.
This kind of exposure is readily hedgable
using forwards, futures or debt

 Economic
risk arises from the real
business risk of the company,
insofar as it is tied to market
interest rates, FX, commodity
prices
 It affects the shareholder value, but
may be difficult to quantify
 Hedging may require tailored
solutions

Inmet Mining Corp.
In 1994 Canadian mining company
Inmet bought 48% of Bougrine, a lead
& zinc mine in Tunisia. Inmet had to
borrow $33 million at a floating rate.
Should it hedge its cost of funds?
 Answer: Business exposure is to lead &
zinc prices (mine shutdown in Oct 96
because of low zinc prices)
 Hedge with digital option linking cost
of funds to lead & zinc prices
