原理:將投資決策和融資決策分開來考慮。允許公司評估項目損益,根據(jù)新的融 資方式。這樣,在估算時,先僅僅考慮商業(yè)風險(用 Kei 折現(xiàn));其次才考慮債 務融資和補貼貸款帶來的好處(節(jié)稅,省息)。這樣公司可以評估投資活動的價值, 以及因融資方式帶來的好處。
APV method separates the investment decision from the financing decision. This will allow company to evaluate the gain or loss associated with the costs and benefits of the new finance.
The value of the project is initially assessed considering only the business risk involved in undertaking the project. The discount rate used is based on the asset beta which measures only the business risk of that company.
The impact of debt financing and the subsidy benefit are then considered. In this way, the company can assess the value created its investment activity and then the additional value created from the manner in which the project is financed.
優(yōu)點:
1.不同資金不同折算率,商業(yè)風險用 Kei,金融風險用 Kd。It allows each different type of cash flow to be discounted at a rate specific to risk of that cash flow.
2.當融資情況較復雜時,此法適用 It also allows the effects of more complex financing situations to be considered
缺點:
Kei 是用 CAPM 計算得來,所以有 CAPM 的理論缺陷。Discounted rate used in base on CAPM, which has number of theoretical weakness.具體是那些不現(xiàn)實的假設: Zero insolvency costs 零破產(chǎn)成本;投資市場有效;投資人有多樣化的投資組合; 完美資本市場;且很難確定 excess return, risk free rate & B 值。
