4. IBM needs to raise $1 billion and is trying to decide between a domestic dollar bond issue and a Eurobond issue. The U.S. bond can be issued at a coupon of 6.75 percent, paid semiannually, with underwriting and other expenses totaling 0.95 percent of the issue size.

Assuming all else is equal, which is the least expensive issue for IBM? (10 marks)
