Make-Whole Refunding Decision
Vantage Grid has $300 million of 6.25% senior notes due 2031, callable at a make-whole premium equal to the present value of remaining scheduled payments discounted at the Treasury rate plus 35 basis points. The notes have 8 years remaining. The current 8-year Treasury yield is 4.10%; the company's new-issue 8-year spread is 150 bp. A new 8-year bond would carry a 5.60% coupon. The make-whole calculation uses the 4.45% discount rate (4.10% + 0.35%) and produces a call premium of $38 million. Issuance costs are $3 million, and the company's marginal tax rate is 25%. The treasurer is comparing refunding now with waiting one year, when the call premium steps down. The company has $50 million of cash and a $200 million revolver with $120 million undrawn. The indenture limits additional secured debt to 10% of tangible net worth ($1.2 billion).
1. Estimate the annual interest savings from refunding and the simple payback period on the call premium and issuance costs.

Old annual interest = 6.25% × $300 million = $18.75 million. New annual interest = 5.60% × $300 million = $16.80 million. Pretax annual savings = $1.95 million; after-tax savings at 25% = $1.4625 million.
Upfront costs = $38 million call premium + $3 million issuance costs = $41 million pretax. If the call premium is currently deductible, the after-tax cost is $41 million × (1 − 25%) = $30.75 million; if it must be capitalized or amortized, the near-term cash cost is the full $41 million. Simple pretax payback = $41 million ÷ $1.95 million = 21.0 years. After-tax payback using the tax-adjusted cost and savings is $30.75 million ÷ $1.4625 million = 21.0 years.
Because the payback period is about 21 years but the new bond would have only an 8-year maturity, the undiscounted savings over the life of the new bond are roughly $15.6 million pretax-well below the $41 million upfront cost. On a payback basis, refunding now is not attractive.
2. Explain why simple payback may misstate the economics and identify the key variables the treasurer should test.

Simple payback ignores the time value of money, the timing of tax deductions, and the fact that the new bond may have a different maturity than the old bond. Here the payback exceeds the 8-year remaining term, which is a strong signal that the refunding destroys value unless the company extends maturity or the call premium falls materially. A discounted cash flow analysis should compare the after-tax cost of the old notes (coupon plus amortized issuance costs) with the after-tax cost of the new notes plus the upfront call premium and financing costs.
Key variables to test include: the make-whole discount rate and the Treasury curve; the tax treatment and amortization period for the call premium; new-issue spread and credit migration; issuance costs; the option value of waiting for the step-down in the call premium; and the indenture's secured-debt basket. The treasurer should also consider refinancing risk and covenant headroom, because adding secured debt or drawing the revolver to pay the premium could reduce flexibility. Waiting may be rational if the premium step-down is large relative to expected rate movements.
