答案最后那个公式是怎么来的？

NO.PZ2018101501000031 问题如下 Company M hinveste$20 million in fixecapitananother $5 million in working capitin a ten-yeproject. The equipment will preciatestraight-line to zero over five years. It will generate aitionannurevenues of $1.5 million anreannucash operating expenses of $0.5 million. After ten years, the equipment will solfor $3 million. The trate anthe requirerate of return are 25% an10% respectively. However, after reappraising the project, the fixecapitinvestment will austewnwar$2 million with no change in salvage value. Whwill happen on the projeNPV? It will increase $2.38 million. It will crease $1.62 million. It will increase $1.62 million. C is correct.考点Cash Flow Projections: Expansion Project解析固定资产投资下降$2 million，折旧会下降$0.4 million，相对应的preciation tsaving会下降 0.25*($2 million/5) = $0.1 million所以NPV最终会增加2 - ∑t=150.11.1t\sum_{t=1}^5\frac{0.1}{1.1^t}∑t=15​1.1t0.1​ = $1.62 million EBIT(1-T) + = (S-C)(1-T) + T，只有小了，所以用来scount的cash flow变小了，为何NPV不是crease而是increase呢？
