A company has a lot of fixed-rate debt (i.e., debt where the interest rate is set in advance and does not change over time) outstanding. Interest rates have dropped substantially since the company issued this debt. The company's Treasurer argues that "because interest rates have dropped, our company should buy back its current debt and issue new debt to save on interest costs." The CFO answers that this only makes sense for "the bonds with call provisions and not on the bonds that we would have to buy back in the market at the market price." A call provision allows the company to force holders of the debt to sell the debt back at par value (i.e., at the price at which it was initially issued). Who is right? Why?
