The Oriels are deciding whether to raise $600 million by issuing a bond, or by borrowing the cash from a bank, to build a new stadium. The organization can offer a 7% coupon rate on a standard, 25-year bond, or the bank will lend the Oriels the funds at a 4.1% for 35 years. Which option should the Oriels choose and why? What would be the difference in total funds paid back to either the bond hold or the bank?
