This document contains calculations related to discounted cash flow (DCF) valuation for three different companies or divisions. It includes calculations of weighted average cost of capital (WACC) using given inputs like debt ratio, cost of debt, beta, tax rate. It also includes projections of revenue, earnings, capital expenditures, depreciation, working capital and free cash flows to the firm. These cash flows are discounted using the WACC to calculate the intrinsic value per share or overall valuation of the company/division. Sensitivity analysis is also performed by varying the assumptions for working capital as a percentage of revenue.
