You are an analyst valuing Palm and Sun Industries for a possible acquisition. Below are pro forma estimates of unlevered free cash flow and interest tax savings for the 3-year planning period. Starting in year 4, you expect a constant growth rate of 4%, which is applicable to both equity- and debt-related cash flows. The unlevered cost of equity is 15% and the cost of debt is 8%. The tax rate is 35%. Cash flows are given in millions. Find the present value of the interest tax shield. Round your answer to the nearest million.

	Year 1	Year 2	Year 3
Free Cash Flow	8	10	13
Tax Savings	2	2	1

Can you show this example in Excel. I am having trouble calculating the interest expense to finish this equation.
