NPV=-$100,000+$40,000/(1+0.10)^1+$40,000/(1+0.10)^2+$40,000/(1+0.10)^3+$40,000/(1+0.10)^4项目ANPV=-$100,000+$36,363.64+$33,057.85+$30,052.59+$27,320.55=$26,794.63项目BNPV=-$150,000+$60,000/(1+0.10)^1+$60,000/(1+0.10)^2+$60,000/(1+0.10)^3+$60,000/(1+0.10)^4项目BNPV=-$150,000+$54,545.45+$49,586.78+$45,078.90+$40,982.81=$39,194.94由于项目B的NPV($39,194.94)高于项目A的NPV($26,794.63)，且为正，nên项目B更优。但题目选项只有A，可能题目或选项有误，或存在特定情境（如互斥项目常选NPV>0且最大的）。按标准NPV方法，项目B更优。34.d)所有以上各项解析思路：加权平均资本成本（WACC）是公司所有资金来源（债务、优先股、普通股权益）的成本的加权平均值。其中，普通股权益成本包括股权成本和留存收益成本（股利增长模型或CAPM计算）。35.b)评估互斥项目时可能给出相互矛盾的结果。解析思路：净现值（NPV）方法在评估互斥项目时，如果项目规模差异较大，可能得出与内部收益率（IRR）方法不同的排序结论，这是NPV方法的一个主要局限性。36.a)折扣率增加。解析思路：现值是未来现金流按照一定折现率计算得出的现在价值。折现率越高，未来现金流折算成的现值就越低。37.a)债券的票面利率降低。解析思路：债券的久期衡量其价格对利率变化的敏感度。久期与票面利率负相关，票面利率越低，久期越长，价格对利率变化的敏感度越高。38.c)现金流量到公司(FreeCashFlowtoFirm-FCFF)估值解析思路：自由现金流到公司（FCFF）是公司在支付了所有运营支出、资本支出和净债务偿还后，可分配给所有投资者的现金流。使用FCFF进行DCF估值是常见的公司整体估值方法。39.d)所有以上各项a)出售子公司的收益是现金流入来源。b)发行新普通股是现金流入来源（尽管资金用途可能用于再投资或偿还债务）。c)支付股利是现金流出，但反过来看，未支付股利的部分属于公司内部现金来源。*修正：通常指经营活动、投资活动、融资活动的现金流入。若必须选，a)是经营或投资活动产生的现金流入。b)是融资活动。c)是融资活动的现金流出。若理解为广义现金来源，则d)最宽泛。此处按常规理解，a)和b)是主要来源。40.c)对每个正在分析的变量使用一系列广泛的值。解析思路：敏感性分析的目的在于了解单个变量变动对结果的影响程度。因此，需要为关键变量设定一个合理的变动范围（如+/-10%,+/-20%），并观察结果的变化。41.a)$100,000解析思路：营运资本=流动资产-流动负债=$200,000-$100,000=$100,000。42.b)总资产周转率解析思路：杜邦分析中的总资产周转率（NetProfitMargin*TotalAssetTurnover）衡量公司利用其全部资产产生销售收入的效率。43.a)$950.00解析思路：该债券每半年支付利息$1,000*6%/2=$30。市场利率（YTM）是半年的，为5%/2=2.5%。使用债券定价公式或财务计算器计算现值。PV=C*[1-(1+r)^-n]/r+F/(1+r)^nPV=$30*[1-(1+0.025)^-10]/0.025+$1,000/(1+0.025)^10PV≈$30*[1-0.7812]/0.025+$781.20PV≈$30*8.0392/0.025+$781.20PV≈$965.15+$781.20=$1746.35*修正：计算器或公式使用错误。PV=$30*PVIFA(2.5%,10)+$1000/PVIF(2.5%,10)PVIFA(2.5%,10)=[1-(1.025)^-10]/0.025≈8.0392PVIF(2.5%,10)=(1.025)^-10≈0.7812PV=$30*8.0392+$1000/0.7812PV≈$241.18+$1276.82=$1518.00*再次修正：利率和期数需统一。YTM5%,N=10.PV=$30*PVIFA(5%,10)+$1000/PVIF(5%,10)
