1、第五章 资本投资与决策指标1. (1) 净现值:NPV = - 195+45 PVIFA(9%,6) = -195 + 45 4.4859 = 6.87现值系数:PI=45 PVIFA(9%,6)195=201.87195=1.04内部收益率:由于 NPV(10%,6)=0.975万元,NPV(11%,6)= -4.625万元 用内差法,(x%/1%)=0.975/(0.957-(-4.625) x/1=(0.975/5.6) x=0.17% 所以IRR = 10%+0.17% = 10.17% (2)因为NPV0(或PI1,或IRR9%),所以该项目可行。2. (1) NPV=18000PV
2、IFA(10%,10) 100000 = 180006.145 - 100000 = 10610(元) (2) NPV=18000PVIFA(15%,10) 100000 = 180005.019 - 100000 = -9662(元) (3) 由于 NPV(12%,10)=1700元,NPV(14%,10)= -6112元 用内差法,(x%/2%)=1700/(1700-(-6112) x/2=(1700/7812) x=0.44 所以IRR = 12% + 0.44% = 12.44% 如果用i=12% 和i=13% 进行内差,IRR=12.42%。3. (1) PPA = 5000015
3、625 = 3.2(年) PPB = 50000/100000 + 4 = 4.5(年) (2) NPVA = - 50000 + 15625 PVIFA(10%,5)= 9231.25 NPVB = - 50000 + 100000 PVIFB(10%,5)= 12092 (3) PVIFA(IRRA,5)= 3.2 IRRA=16%+2%(3.2743 - 3.2)(3.2743 - 3.1272)=16.99% PVIF(IRRB,5)= 0.5 IRRB=14%+(0.5194 - 0.5)(0.5194 - 0.4972)=14.87% (4) i=1515625*(1+10%)5-
4、i(1+MIRRA)5=50000,MIRRA=13.79%100000(1+MIRR)5=50000,MIRRB=IRRB=14.87%4.NPV=-200+2351+11.5%+-651+11.5%2+300(1+11.5%)3=174.895. (1)NPVA=5100PVIFA(14%,5) 17100 = 408.71NPVA=7500PVIFA(14%,5) 22430 = 3318.11(2)5100PVIFA(IRRA,5) = 17100,IRRA=15%7500PVIFA(IRRB,5) =22430,IRRB=20%(3)i=155100*(1+14%)5-i(1+MIR
5、RA)5=17100,MIRRA=14.53%i=157500*(1+10%)5-i(1+MIRRB)5=22430,MIRRB=17.19%两个项目均具有正的NPV,且内部回报率高于资本成本,调整的内部回报率也高于资本成本,因此接受项目。6. NPVS=-1000+9001.1+2501.12+101.13+101.14=39.14NPVI=-1000+2501.12+4001.13+8001.14=53.55IRRS=13.5%, IRRL=11.8%考虑S-L项目,对应的现金流如下:年度01234现金流09000-390-790S-L项目的NPV为:NPVSL=9001.1+-3901.
6、13+-7901.14=-14.4因此,L项目更好,对应的内部回报率为11.8%7. 100=i=15CF1+10%i,可得每期的现金流流入为26.38万元。i=1526.38*(1+8%)5-i(1+MIRR)5=100,MIRR=9.13%8. 两年后公司开始投产。NPV=-900+i=15350(1+13.5%)i+1-1501+13.5%=39.35900=i=15350(1+IRR)i+1-1501+IRR,IRR=14.68%假设每年赔偿额为x,最大赔偿额满足:-900+i=15350-x(1+13.5%)i+1-1501+13.5%=0X=12.85因此每年赔偿额不能超过12.8
7、5万元。9. 考虑休闲楼减去写字楼后的现金流:01234567休闲中心-300-387-193-100600600850-150写字楼-405140140140140140140140休闲-写字楼105-527-333-240460460710-290PV(休闲-写字楼)105-479.09-275.21-180.32314.19285.62400.78-148.82因此,NPV(写字楼)=276.58,NPV(休闲中心)=298.74,NPV(休闲-写字楼)=22.16所以在资本成本为10%时,选择休闲中心。同理,在资本成本为15%时,NPV(写字楼)=177.46,NPV(休闲中心)=104.23,NPV(休闲-写字楼)=-73.22,此时应该选择写字楼。10. T=5:NPV=-22000+i=156500(1+10%)i=2640T=4:NPV=-22000+i=146500(1+10%)i+7000(1+10%)4=3385.2T=3:NPV=-22000+i=136500(1+10%)i+11000(1+10%)3=2429T=2:NPV=-22000+i=126500(1+10%)i+14000(1+10%)2=851.2T=1:NPV=-22000+i=116500(1+10%)i+18000(1+10%)1=272.73因此,应该选择在第四年末卖出。
