I.A. Glossary, continued
Organized Exchange - centralized location where organized trading is conducted
in certain financial instruments under a specific set of rules.
The exchange clearinghouse is the counter-party to every transaction;
members of the exchange share the responsibility of fulfilling commitments.
The exchange:
(i) Sets standardized terms for all contracts traded,
(ii) Often places restrictions on trading (e.g., margin, price limits, ...).
(iii) Standardization of contracts and other rules make clearing easier,
reduce uncertainty about counterparty default risk,
and help ensure an orderly market.
Over-the-Counter (OTC) Market - any market where transaction takes place
other than an organized exchange; e.g., thru financial institution or broker.
Arbitrage Portfolio - (i) uses none of your own money; (ii) has no risk.

Debt Instrument, Bond - Prior, fixed claim against earnings & assets of firm.
Equity Instrument, Stock - Residual ownership claim against earnings & assets.
Forward Contract - commitment by two parties to exchange a particular good
for a specific price (F) at a specified future time (Expiration, Maturity);
No cash exchanges hands initially;
At expiration cash exchanged for the consideration specified in the contract;
Traded OTC; Customer typically required to post margin.
Futures Contract - same as Forward, except profits / losses are computed
and settled (marked-to-market) on a daily basis rather than only at maturity;
typically traded on organized exchange.
Financial Futures - futures contract in which the good to be delivered
is a financial instrument.

II. Corporate Uses of Derivatives
Survey of Managers of Fortune 500 Companies.
A. Why do firms use derivatives? 1. Hedge Transaction Exposure. (Cost / Rev = P x Q; Q fixed)
2. Hedge Economic Exposure. (Cost / Rev = P x Q; neither fixed)
3. Reduce Funding Costs. (Reduce risk; lower cost of capital)
4. Trade for Profit. (Speculate; take risks with deriv.’s)
B. What derivatives? 1. To manage foreign exchange exposure,
Use OTC forwards, SWAPs, & options,
then exchange-traded futures & options.
2. To manage interest rate exposure,
Use OTC SWAPs, options (e.g., caps, floors, ... ),
then exchange-traded futures & options.

V. Accounting
A. Problems presented by derivatives.
1. How & when to recognize transactions.
2. How & when to recognize value changes.
3. How to regard different claims (e.g., Debt or Equity?).
4. Point: Many derivatives used to remain unrecognized,while others were recognized & measured,some at market value, others based on past prices.
5. In 2000, FAS #133 was implemented (revision of FAS #52 & #80):a. Derivatives gains / losses booked as earnings unless bona fide hedge.
Then deriv. gains / losses matched against losses / gains over the life.
B. Hedge Accounting.
1. Set of rules to recognize changes in values of components of hedge
so that counterbalancing changes in fair values of hedged items
and hedging instruments are included in earnings in same period.

V. Accounting
C. Taxation.
1. Issue: whether gains / losses on hedge will be
treated as ‘ordinary income’ or ‘capital gains / losses’ for taxes.
a. Boils down to asymmetric tax treatment.
2. History of inconsistent treatments.
3. Current policy (FAS #133):
Gains / losses on derivatives are treated as ordinary income
for tax purposes, if it can be shown that purpose is truly to hedge;
Otherwise, treated as capital gains / losses.
These gains / losses on the hedging asset (the derivative)
may be matched against losses / gains on the asset being hedged,
and amortized over the life of the hedge.

V. How Risk Management Can Add Value
Value of firm j = Vj = Σ E(NCFjt) / (1 + rjt )t .
Vj will increase only if: (i) rjt ; (ii) E(NCFjt) .
A. Impact of risk management on rjt .
1. Risk management will decrease volatility of Vj .
a. This should decrease the firm’s beta;
b. This should decrease probability of default.
2. Both 1.a & 1.b should make investors willing to
pay more for the firm’s debt and equity.
This should reduce the firm’s cost of capital (rjt).

V. How Risk Management Can Add Value
B. Impact of risk management on E(NCFjt).
1. Risk Management can add value by decreasing taxes.
a. Hedging reduces probability that income will be too low to take advantage of tax shields.
b. Derivatives allow firm to obtain accrual (hedge) accounting tax treatment for risk management.
c. Derivatives can be used to take advantage of asymmetries in tax treatment (e.g., across borders).
2. Risk Management can add value by decreasing transaction costs.
a. Firms can adjust exposure by selling some assets and buying others, or by trading derivatives; derivatives cheaper.
b. Risk management reduces the expected costs resulting from risk of financial distress.

V. How Risk Management Can Add Value
3. Risk Management can add value by helping firm to
avoid bad investment decisions.
a. Firm may turn down positive NPV projects:
i. If firm is in financial distress;
ii. Due to conflict between shareholders & debtholders.
4. Derivatives can be used to assure debtholders:
a. By attaching restrictive covenants to debt;
b. By making the debt convertible;
c. By issuing preferred stock instead of debt (to reduce probability of future default);
d. If risk management reduces probability of default, firm is less likely to turn down good opportunities.
