Derivatives
Derivatives should not scare you!  They really are not that difficult to understand.  They are volatile which have led many to lose enormous amounts of money, but the derivatives in and of themselves are not difficult.  So relax.

Introduction

My introduction to Options (needs updating 11/6/03)
My introduction to other derivatives such as futures and swaps. 

A glossary of risk management terms is available at the Treasury Management Association of Canada 's site.  It is fairly complete and quite good.  Yahoo's finance site has a good Frequently Asked Questions section for basic derivatives that answers some of the practival questions people have who want to trade options.

Swaps

Interest rate swaps are powerful tools to hedge interest rate risk.  Here is an excellent link that explains interest rate swaps as well as another source for information on interest rate swaps
 

Pricing Options

The two most common ways to price options are the Balck-Scholes Formula and the Binomial Option Pricing model. 

     Notes on the Black-Scholes Fomula

My own class notes on the Black-Scholes formula. 
Kevin Rubash from Bradley has a great site on the B-S Model.
About.com has simply excellent coverage.  Even a calculator!

Not sure what volatility to use?  Numa has a good discussion of it!

Pricing options on your computer?  Here is a very cool calculator that will look up historical volatility for you and give you the "Correct price" as well as the actiual price.
 

     Notes on the Binomial Option Pricing Model

Philip H. Dybvig of Washington University has a very good notes on the binomial option pricing model.
A discussion of the Cox-Rubenstein 's model.

Joaquin R. Trigueros at Tulane offers a binomial pricing calculator.

Much more rigorous, but good for the "expert."

Why Hedge?

A common problem with derivatives is that the user is unsure of why derivatives are being used.  This centers on risk management   which is a very important field that generally does not get the coverage it warrants in an undergraduate course.

Want to know why firms hedge?  The answer in " note form " is here, it is also available in " working paper " form from Allayannis and Weston from UVA..  Nut shell reason?  It can increase shareholder wealth!
