The three most common ways where companies use derivatives for
hedging include foreign exchange risks, hedging interest rate risk,
and commodity or product input hedge. These derivatives help to
protect the company from unanticipated events: adverse foreign
exchange or interest rate movements and unexpected increases in
input costs.
There are several reasons why firms may choose to hedge risks,
and they can be broadly categorized into five groups. First, the
tax laws may benefit those who hedge risk. Second, hedging against
catastrophic or extreme risk may reduce the likelihood and the
costs of distress. Third, hedging against risks may reduce the
under investment problem prevalent in many firms as a result of
risk averse managers and restricted capital markets. Fourth,
minimizing the exposure to some types of risk may provide firms
with more freedom to fine tune their capital structure. Lastly,
investors may find the financial statements of firms that do hedge
to be more informative than firms that do not.
- Tax Benefits - A firm that hedges against risk
may receive tax benefits as against a similar firm that does not
hedge against risk. There are two sources for these tax benefits.
One comes from the smoothing of earnings that is a consequence of
effective risk hedging; with risk hedging, earnings will be lower
than they would otheriwse have been without hedging, during periods
where the risk does not manifest itself and higher in periods where
there is risk exposure.The other tax benefit arises from the tax
treatment of hedging expenses and benefits. There will be a tax
benefit to hedging if the cost of hedging is fully tax deductible
but the benefits from insurance are not fully taxed.
- Better investment decisions - By allowing
managers to hedge firm-specific risks, risk hedging may reduce the
number of good investments that get rejected either because of
managerial risk aversion or lack of access to capital.
- Distress Costs - Every business, no matter how
large and healthy, faces the possibility of distress under
sufficiently adverse circumstances. Given the large costs of
bankruptcy, it is prudent for firms to protect themselves against
risks that may cause distress by hedging against them. Generally
speaking, these will be risks that are large relative to the size
of the firm and its fixed commitments (such as interest payments).
For example, while large firms with little debt like Coca Cola can
easily absorb the costs of exchange rate movements, smaller firms
and firms with larger debt obligations may very well be pushed to
their financial limits by the same risk. Consequently, it makes
sense for the smaller firms to hedge against risk.
- Capital Structure - In general, firms that
perceive themselves as facing less distress costs are likely to
borrow more. Additional borrowing creates a tax benefit, this
implies that a firm that hedges away large risks will borrow more
money and have a lower cost of capital. The payoff will be a higher
value for the business.
A significant number of firms hedge their risk exposures, with
wide variations in which risks get hedged and the tools used for
hedging. While a significant proportion of firms hedge against
risk, some risks seem to be hedged more often than others.
