You are an analyst in a major investment bank and have been assigned the task of determining the share price of Foodmart, a national supermarket chain. The stock beta is 1.286, Rf=3% and Rm=10%. The cost of debt is 6.82%. The tax rate is 34% and the firm is 40% debt financed. (a) Calculate the WACC for Foodmart. (b) The firm’s expected cash flow for this year is $60 million.

Calculate the target price. Show all work.  Asset = C1[1- ((1+gs)/(1+k))n] / (k-gs) + {C1(1+gs)n-1(1+gn)}/{k-gn)(1+k)n}     K = Ke(E/V) + Kd(1-t)(B/V)

Find the limit:  a)
