题型:单项选择题

M公司目前拥有资金6 000万元,其中,长期借款2 400万元,年利率10%;普通股 3600万元,上年支付每股股利2元,预计以后各年股利增长率为5%,股票发行价格20元,目前价格也为20元。
M公司为生产A产品,急需购置一台价值为2 000万元的W型设备,该设备购入后即可投入生产使用。预计使用年限为4年,预计净残值率为1%。按年限平均法计提折旧。
经测算,A产品的单位变动成本(包括销售税金)为600元,边际贡献率为40%,固定成本总额为1 250万元,A产品投产后每年可实现销售量4万件。
为购置该设备,M公司计划再筹集资金2 000万元,有两种筹资方案:
方案甲:增加长期借款2000万元,借款利率为12%,筹资后股价下降到18元,不考虑筹资费用,其他条件不变。
方案乙:增发普通股80万股,普通股市价上升到每股25元,其他条件不变。
已知当年限为4年、年利率为10%时,1元的复利现值系数和终值系数分别为0.683和 1.464,1元的年金现值系数和终值系数分别为3.17和4.641。企业所得税税率为25%。
根据上述资料,回答下列各题:

若资金成本为10%,则M公司购置W型设备这一投资项目的净现值为( )万元。

A.414.935
B.401.275
C.747.785
D.845.785
