What is the relationship of a warrant and a convertible bond to a call option?

Both a warrant and a convertible bond contain a call option. A warrant is a call option. The holder of the warrant can force the company to deliver a specified number of shares of its stock to be paid for with cash. Warrants differ from other call options only in that they are issued by the company whose stock can be called. A convertible bond is the combination of a bond and a call option. The bond’s owner can force the company to deliver a specified number of shares of its stock to be paid for with the bond. And, like a warrant, the option is granted by the company whose stock can be called.
