8-5 Calculating Cash Flow (This section comes from undergraduates text book, Fundamentals of Corporate Finance) 3 components of a project cash flow:total cash flow = cash flow from investment in plant and equipment+ cash flow from investment in working capital+ cash flow from operations Capital Investment (or Investment in Plant and Equipment)Example 8-4: Slick invests $800 million to develop a razor(刮鬍刀) blade(刀片). The blade factory(廠房) will run 7 years. At year 7, the machinery will be sold for $50 million (i.e., a salvage value 殘值). Taxes of $10 million will be assessed on the sale. t=0 t=7 Capital Investment+$800-$40 (=$50-$10) Investment in Working CapitalExample 8-5: Slick makes investments in inventories. t=0 t=1 t=2 t=3 t=4t=5 t=6 t=7 Working Capital $10 $30 $30 $30 $30 $25 $25 $0Cash Outflows $10$20 $0 $0 $0 -$5 $0 -$25 point: An increase in working capital is an investment and implies a negative cash flow; a decrease in working capital implies a positive cash flow. = The cash flow is measured by the change in working capital, not the level of working capital. Cash Flow from Operations 3 methods to work out(解決、計(jì)算) this component: 1) Cash Flow from Operations = Revenue Cash Expenses Taxes a note: Depreciation is not a cash expense. 2) Cash Flow from Operations = After-Tax Profit + Depreciation 3) Cash Flow from Operations = (Revenue Cash Expenses) (1 tax rate) + (Depreciation tax rate) a note: depreciation tax shield (折舊稅盾，既折舊費(fèi)用帶來(lái)的節(jié)稅) Although depreciation is not a cash expense, it does affect profits (shown on the Income Statement) and therefore taxes paid.If a firms tax bracket(稅級(jí)) is 35%, each dollar of depreciation reduces taxable income(課稅所得) by $1. Tax payments therefore fall by $0.35, and cash flow increases by the same amount.= depreciation tax shield = depreciation tax rate Example 8-6: a simple income statementRevenues$1,000- Cash Expenses 600- Depreciation Expense 200 Profit before tax $200- Tax at 35% 70 Net Income $130 method 1: Cash Flow from Operations = $1,000 - $600 - $70 = $330 method 2: Cash Flow from Operations = $130 + $200 = $330 method 3: Cash Flow from Operations = ($1,000 - $600) (1 0.35) + ($200 0.35) = $260 + $70 = $3308-6 A Complete Example: Blooper Industries Blooper is about to analyze for mining a small deposit of magnoosium ore(礦石).

Q: Could Blooper get those tax shields sooner so that they would be worth more? A: Tax law allows accelerated depreciation(加速折舊).
