the NPV method incorporates the benefit of tax shields from tax-duductible interest payment in the discount rate (ie. the WACC). To avoid double counting these tax shield, interest payment must not be deducted from the cash flows
CF=EBIT*(1-T) +Depr. -CAPEX- increase in Net working capital+ other
前面一句说NPV方法考虑了利息通过减少税务支出从而影响了CF, 这个好理解, 而且在折现的时候使用了WACC也考虑了debt产生利息的减税作用。 但是我的问题是后面一句话说, 不能给把利息费用从CF中减掉, 这样才能不至于double counting。 请问如果减掉了利息, 就会对tax shield的影响进行double counting吗?
谢谢!
