Which of the following statements is FALSE? Group of answer choices When bond yields have increased, by exercising the call on the callable bond and then immediately refinancing, the issuer can lower its borrowing costs. To understand how call provisions affect the price of a bond, we first need to consider when an issuer will exercise its right to call the bond.
