Use the following information to answer the question(s) below.
Rearden Metal is considering the purchase of a new blast furnace costing a total of $5 million dollars.This furnace will qualify for accelerated depreciation: 20% can be expense immediately,followed by 32%,19.2%,11.52%,11.52% and 5.76% over the next five years.However,because of Rearden's substantial tax loss carry forwards,Rearden estimates its marginal tax rate to be only 10% over the next five years.Since Rearden will get very little tax benefit from the depreciation expense,they consider leasing the furnace instead.Suppose that Rearden and the lessor face the same 8% borrowing rate,but the lessor has a 40% marginal tax rate.Assume that the furnace is worthless after five years,the lease term is five years,and a lease would qualify as a true tax lease.
-Assuming that Rearden's annual lease payments are $1.1 million,then the effective after-tax lease borrowing rate is closest to:

A) 8.0%
B) 12.8%
C) 15.4%
D) 17.0%
