Hi everyone,

i'm at the Fixed Income chapter, and see this:

Price of callable bond = Price of option-free bond - Price of embedded call option

Just confused regarding the difference between callable bond and bond with embedded call option.

Is embedded call option, a bond option? whereby it is an option to buy the bond?
Or is it a bond that has an option for the issuer to call back the bond? if it's the latter, how is it different from callable bond?
