Convertible bonds are almost always callable. This means that a convertible bond is
really a package of three securities: a straight bond, a call option held by the bondholder
(the conversion feature), and a call option held by the corporation (the call provision).


Put Bonds Put bonds are a relatively new innovation. The owner of a put bond has
the right to force the issuer to repurchase the bond at a fixed price for a fixed period of
time. Such a bond is a combination of a straight bond and a put option; hence the name.
For example, in Chapter 7, we briefly discussed a LYON, a liquid yield option note.
This is a callable, puttable, convertible, pure discount bond. It is thus a package of a
pure discount bond, two call options, and a put option.


Insurance and Loan Guarantees Insurance of one kind or another is a financial fea-
ture of everyday life. Most of the time, having insurance is like having a put option. For
example, suppose you have $1 million in fire insurance on an office building. One night,
your building burns down, which reduces its value to nothing. In this case, you will ef-
fectively exercise your put option and force the insurer to pay you $1 million for some-
thing worth very little.
Loan guarantees are a form of insurance. If you loan money to someone and they de-
fault, then, with a guaranteed loan, you can collect from someone else, often the gov-
ernment. For example, when you loan money to a commercial bank (by making a
deposit), your loan is guaranteed (up to $100,000) by the government.
In two particularly well-known cases of loan guarantees, Lockheed (now Lockheed
Martin) Corporation (in 1971) and Chrysler (now DaimlerChrysler) Corporation (in
