Estimate the value of a firm $($P$0)$ whose cash flow is projected to grow at a compound annual average rate of $35\%$ for the next five years and then assume a more normal $5\%$ annual growth rate. The current year$$s cash flow is $$4$ million. The firm$$s weighted average cost of capital during the high growth period is $18\%$ and then drops to the industry average rate of $12\%$ beyond the fifth year.
