costs of refunding can also be very large.
Perspective 16-6: Compare the refunding decision with paying off a high-cost mortgage
early and refinancing it at a lower rate with all the resultant costs of financing, points, closing
fees, lawyers, etc. Notice that all present value examples have calculator keystroke solution in
the margin.
C. A refunding decision is nothing more than a capital budgeting problem. The
refunding costs constitute the investment. The net reduction in annual cash
expenditures are the inflows.
1. Outflow Considerations:
a. The after tax cost of the call premium
b. The Underwriting Cost on the new issue less the PV of the future
tax savings (on the new underwriting cost)
2. Inflow Considerations:
a. The present value of the after tax savings on the difference in the
interest rates
b. Tax benefit from the immediate write off of the remaining
unamortized underwriting cost of old issue. (The difference
between immediate write off of remaining value and the PV of
annual write off times the tax rate.)
3. Net Present Value: Inflows minus outflows equals Net Present Value.
PPT Net Present Value
D. A major difference in evaluating a capital expenditure for refunding is that the
discount rate applied is the aftertax cost of debt rather than the cost of capital
because the annual savings are known with greater certainty.
V. Other Forms of Bond Financing
A. Zero-Coupon Rate Bonds
1. Do not pay interest; sold at deep discounts from face value.
2. These bonds provide immediate cash inflow to the corporation (sell
bonds) without any outflow (interest payments) until the bonds mature.
3. Since the difference between the selling price and the maturity value is
amortized for tax purposes over the life of the bond, a tax reduction
benefit occurs without a current cash outflow.
4. Allows investor to “lock-in” a multiplier of the initial investment.
