You have been assigned the task of using the corporate, or free cash flow $($FCF$),$ model to estimate Petry Corporation's intrinsic value. The firm's Weighted Average Cost of Capital $($WACC$)$ is $10\mathrm{.}00\%,$ its end$-$of$-$year free cash flow $($FCF$1)$ is expected to be $$50\mathrm{.}0$ million, and the FCFs are expected to grow at a constant rate of $5\mathrm{.}00\%$ a year into the future. The company has $$200$ million of long$-$term debt and preferred stock, and it has $30$ million shares of common stock outstanding. Assume the firm has zero non$-$operating assets. a$.$ Discuss how the corporate, or free cash flow, model can be used to estimate a firm's intrinsic value. What are the key assumptions underlying this model? $(4$ marks$)$b$.$ Discuss the importance of the Weighted Average Cost of Capital $($WACC$)$ in the context of corporate valuation. How does WACC affect the valuation process? $(4$ marks$)$c$.$ Using the corporate valuation model, calculate the value of Petry Corporation based on the given data. $(4$ marks$)$d$.$ Determine the intrinsic value per share of Petry Corporation's common stock. $(4$ marks$)$
