Rogers Communication is considering whether to take advantage of historically low Canadian interest rates and lower its cost of debt by refunding its old bonds. Rogers has a $50million bond issue outstanding with a 12 percent annual coupon. These 15 year bonds were sold 5 years ago, and can be called in at a 10% call premium. According to investment bankers, the firm can sell $60million, 10 year bonds with an annual coupon rate of 8 percent, and floatation costs of $5million. Rogers' marginal tax rate is 40%. The new bonds will be sold one month before the old issue is called, and funds can be invested in treasury bills yielding 8%. The additional $10million from the new bond issue could be invested in a 10 year project with an expected NPV of $2.5million. Should Rogers proceed with the refunding? The answer should show all four working steps.
