公司理财罗斯第九版课后习题答案

罗斯《公司理财》第9版精要版英文原书课后部分章节答案详细? 1 / 17 CH5 11,13,18,19,20 11. To find the PV of a lump sum, we use: PV = FV / (1 + r) t PV = $1,000,000 / (1.10) 80 = $488.19 13. To answer this question, we can use either the FV or the PV formula. Both will give the same answer since they are the inverse of each other. We will use the FV formula, that is: FV = PV(1 + r) t Solving for r, we get: r = (FV / PV) 1 / t –1 r = ($1,260,000 / $150) 1/11 2 – 1 = .0840 or 8.40% To find the FV of the first prize, we use: FV = PV(1 + r) t FV = $1,260,000(1.0840) 3 3 = $18,056,409.9 4 18. To find the FV of a lump sum, we use: FV = PV(1 + r) t FV = $4,000(1.11) 4 5 = $438,120.97 FV = $4,000(1.11) 35 = $154,299.40 Better start early! 19. We need to find the FV of a lump sum. However, the money will only be invested for six years, so the number of periods is six. FV = PV(1 + r) t FV = $20,000(1.084) 6 = $32,449.33 20. To answer this question, we can use either the FV or the PV formula. Both will give the same answer since they are the inverse of each other. We will use the FV formula, that is: FV = PV(1 + r) t Solving for t, we get: t = ln(FV / PV) / ln(1 + r) t = ln($75,000 / $10,000) / ln(1.11) = 19.31 So, the money must be invested for 19.31 years. However, you will not receive the money for another two years. From now, you’ll wait: 2 years + 19.31 years = 21.31 years CH6 16,24,27,42,58 16. For this problem, we simply need to find the FV of a lump sum using the equation: FV = PV(1 + r) t 2 / 1 7 It is important to note that compounding occurs semiannually. To account for this, we will divide the interest rate by two (the number of compounding periods in a year), and multiply the number of periods by two. Doing so, we get: FV = $2,100[1 + (.084/2)] 34 = $8,505.93 24. This problem requires us to find the FVA. The equation to find the FVA is: FV A = C{[(1 + r) t – 1] / r} FV A = $300[{[1 + (.10/12) ] 360 – 1} / (.10/12)] = $678,146.3 8 27. The cash flows are annual and the compounding period is quarterly, so we need to calculate the EAR to make the interest rate comparable with the timing of the cash flows. Using the equation for the EAR, we get: EAR = [1 + (APR / m)] m – 1 EAR = [1 + (.11/4)] 4 – 1 = .1146 or 11.46% And now we use the EAR to find the PV of each cash flow as a lump sum and add them together: PV = $725 / 1.1146 + $980 / 1.1146 2 + $1,360 / 1.1146 4 = $2,320.36 42. The amount of principal paid on the loan is the PV of the monthly payments you make. So, the present value of the $1,150 monthly payments is: PVA = $1,150[(1 – {1 / [1 + (.0635/12)]} 360 ) / (.0635/12)] = $184,817.42 The monthly payments of $1,150 will amount to a principal payment of $184,817.42. The amount of principal you will still owe is: $240,000 – 184,817.42 = $55,182.58 This remaining principal amount will increase at the interest rate on the loan until the end of the loan period. So the balloon payment in 30 years, which is the FV of the remaining principal will be: Balloon payment = $55,182.58[1 + (.0635/12)] 360 = $368,936.54 58. To answer this question, we should find the PV of both options, and compare them. Since we are purchasing the car, the lowest PV is the best option. The PV of the leasing is simply the PV of the lease payments, plus the $99. The interest rate we would use for the leasing option is the same as the interest rate of the loan. The PV of leasing is: PV = $9 9 + $450{1 –[1 / (1 + .07/12) 12(3) ]} / (.07/12) = $14,672.91 The PV of purchasing the car is the current price of the car minus the PV of the resale price. The PV of the resale price is : PV = $23,000 / [1 + (.07/12)] 12(3) = $18,654.82 The PV of the decision to purchase is: $32,000 – 18,654.82 = $13,345.18 3 / 17 In this case, it is cheaper to buy the car than leasing it since the PV of the purchase cash flows is lower. To find the breakeven resale price, we need to find the resale price that makes the PV of the two options the same. In other words, the PV of the decision to buy should be: $32,000 – PV of resale price = $14,672.91 PV of resale price = $17,327.09 The resale price that would make the PV of the lease versus buy decision is the FV of

罗斯《公司理财》第9版笔记和课后习题(含考研真题)详解[视频详解] 第13章风险、资本成本和资本预算[视频讲解] 13.1复习笔记 运用净现值法,按无风险利率对现金流量折现,可以准确评价无风险现金流量。然而,现实中的绝大多数未来现金流是有风险的,这就要求有一种能对有风险现金流进行折现的方法。确定风险项目净现值所用的折现率可根据资本资产定价模型CAPM(或套利模型APT)来计算。如果某无负债企业要评价一个有风险项目,可以运用证券市场线SML来确定项目所要求的收益率r s,r s也称为权益资本成本。 当企业既有债务融资又有权益融资时,所用的折现率应是项目的综合资本成本,即债务资本成本和权益资本成本的加权平均。 联系企业的风险贴现率与资本市场要求的收益率的原理在于如下一个简单资本预算原则:企业多余的现金,可以立即派发股利,投资者收到股利自己进行投资,也可以用于投资项目产生未来的现金流发放股利。从股东利益出发,股东会在自己投资和企业投资中选择期望收益率较高的一个。只有当项目的期望收益率大于风险水平相当的金融资产的期望收益率时,项目才可行。因此项目的折现率应该等于同样风险水平的金融资产的期望收益率。这也说明了资本市场价格信号作用。 1.权益资本成本 从企业的角度来看,权益资本成本就是其期望收益率,若用CAPM模型,股票的期望收益率为:

其中,R F是无风险利率,是市场组合的期望收益率与无风险利率之差,也称为期望超额市场收益率或市场风险溢价。 要估计企业权益资本成本,需要知道以下三个变量:①无风险利率;②市场风险溢价; ③公司的贝塔系数。 根据权益资本成本计算企业项目的贴现率需要有两个重要假设:①新项目的贝塔风险与企业风险相同;②企业无债务融资。 2.贝塔的估计 估算公司贝塔值的基本方法是利用T个观测值按照如下公式估计: 估算贝塔值可能存在以下问题:①贝塔可能随时间的推移而发生变化;②样本容量可能太小;③贝塔受财务杠杆和经营风险变化的影响。 可以通过如下途径解决上述问题:①第1个和第2个问题可通过采用更加复杂的统计技术加以解决;②根据财务风险和经营风险的变化对贝塔作相应的调整,有助于解决第3个问题;③注意同行业类似企业的平均β估计值。 根据企业自身历史数据来估算企业贝塔系数是一种常用方法,也有人认为运用整个行业的贝塔系数可以更好地估算企业的贝塔系数。有时两者计算的结果差异很大。总的来说,可以遵循下列原则:如果认为企业的经营与所在行业其他企业的经营十分类似,用行业贝塔降低估计误差。如果认为企业的经营与行业内其他企业的经营有着根本性差别,则应选择企业的贝塔。 3.贝塔的确定 前面介绍的回归分析方法估算贝塔并未阐明贝塔是由哪些因素决定的。主要存在以下三个因素:收入的周期性、经营杠杆和财务杠杆。

第十章:风险与收益:市场历史的启示 1. 因为公司的表现具有不可预见性。 2. 投资者很容易看到最坏的投资结果,但是确很难预测到。 3. 不是,股票具有更高的风险,一些投资者属于风险规避者,他们认为这点额外的报酬率还不至于吸引他们付出更高风险的代价。 4. 股票市场与赌博是不同的,它实际是个零和市场,所有人都可能赢。而且投机者带给市场更高的流动性,有利于市场效率。 5. 在80 年代初是最高的,因为伴随着高通胀和费雪效应。 6. 有可能,当投资风险资产报酬非常低,而无风险资产报酬非常高,或者同时出现这两种现象时就会发生这样的情况。 7. 相同,假设两公司2 年前股票价格都为P0,则两年后G 公司股票价格为 1.1*0.9* P0,而S 公司股票价格为0.9*1.1 P0,所以两个公司两年后的股价是一样的。 8. 不相同,Lake Minerals 2年后股票价格= 100(1.10)(1.10) = $121.00 而SmallTown Furniture 2年后股票价格= 100(1.25)(.95) = $118.75 9. 算数平均收益率仅仅是对所有收益率简单加总平均,它没有考虑到所有收益率组合的效果,而几何平均收益率考虑到了收益率组合的效果,所以后者比较重要。 10. 不管是否考虑通货膨胀因素,其风险溢价没有变化,因为风险溢价是风险资产收益率与无风险资产收益率的差额,若这两者都考虑到通货膨胀的因素,其差额仍然是相互抵消的。而在考虑税收后收益率就会降低,因为税后收益会降低。 11. R = [($104 – 92) + 1.45] / $92 = .1462 or 14.62% 12. Dividend yield = $1.45 / $92 = .0158 or 1.58% Capital gains yield = ($104 – 92) / $92 = .1304 or 13.04% 13. R = [($81 – 92) + 1.45] / $92 = –.1038 or –10.38% Dividend yield = $1.45 / $92 = .0158 or 1.58% Capital gains yield = ($81 – 92) / $92 = –.1196 or –11.96% 14.

(公司理财)公司理财中文版第九版第三章答案

第三章财务报表分析与长期财务规划 1.由于不同行业的公司在财务比率上存在很大的差异,财务比率本身提供的信息有限,分析公司的财务比率有两种基本方法:时间趋势分析法和同类公司分析。为什么这些方法会有用呢?每种方法能够告诉你哪些关于公司财务健康状况的信息? 答:时间趋势分析描绘了公司财务状况随时间而变化的图景。通过公司本身的跨期比较分析,财务经理可以评价公司的经营、融资或投资活动的某些方面是否已经发生了变化。同类公司比较分析涉及到将某一特定公司的财务比率和经营绩效与同一行业或业务相同的其他公司进行比较。通过同类公司比较分析,财务经理可以评价公司的经营、融资或投资活动的某些方面是否越出常规,从而为调整这些比率采取恰当的行动提供指南,如果这种调整合适的话。两种方法都从财务的视角研究一个公司究竟有什么不同,但两种方法都不能告诉我们这种不同是积极正面的还是消极负面的。例如,假设一个公司的流动比率是随时间而提高,这可能意味着该公司在过去一直面临流动性问题,一直在纠正这些问题;或者它也可能意味着该公司已经在管理流动资产和负债方面变得更低效。同类公司比较分析中也存在类似的争论。一个公司的流动比率低于同类公司,也许是它在管理流动资产和负债方面更具效率,也可能是它面临流动性问题。没有哪种方法告诉我们某个比率是好还是坏。两种方法只是表明有些东西存在差异,并告诉我们去哪里寻找。 2.所谓的“同店销售”是像沃尔玛和希尔斯之类的十分分散的公司的

一项重要指标,顾名思义,分析同店销售就是比较同样的店铺或餐馆在两个不同的时间点上的销售额。为什么公司总是关注同店销售而不是总销售? 答:如果一家公司通过开设新店来不断增长,那么可以推测其总收入将上升。比较两个不同时点的总销售额可能会误导。同店销售方法只看在特定时期开设的店铺的销售额控制了这一误差。 3.为什么多数长期财务计划都从销售预测开始?或者说,为什么未来销售额是关键? 答:理由是,最终,消费是商业背后的驱动力。一个企业的资产、雇员,事实上,几乎企业经营和融资的所有方面都是直接或间接地支持销售。换种说法,一个企业对资本资产、雇员、存货以及融资的未来需求都由它的未来销售所决定。 4.本章利用Rosengarten公司说明EFN的计算,Rosengarten的ROE 约为7.3%,利润再投资率约为67%,如果你为Rosengarten计算可持续增长率,会发现它只有 5.14%,而我们在计算EFN时所使用的增长率为25%,这可能吗?(提示:有可能。如何实现?) 答:可持续增长公式的两个假设是,公司并不想出售新的股票,以及财务政策是固定的。如果公司增加外部股权,或提高其债务权益比率,它的增长速度可以比可持续增长率更高。当然,如果公司改变其股利政策,提高留成比例,或其总资产周转率提高,它的增长速度也可以快于它的销售净利率提高的速度。 5.

第九版 公司理财 罗斯 中文答案 第四章

1、FV=PV*(1+R)^T,PV= FV/(1+R)^T,所以时间长度增加时,终值会 增加,现值会减少。 2、FV=PV*(1+R)^T,PV= FV/(1+R)^T,利率增加时,年金的终值会增 加,现值会减少。 3、第一种情况:PV=C*{[1-1/(1+r)^T]/r}=1000*{[1-1/(1+r)^10]/r} 第二种情况:PV=C*{[1-(1+g)^T/(1+r)^T]/(r-g)}= 1000*{[1-(1+5%)^10/(1+r)^10]/(r-5%)} 1000*{[1-1/(1+r)^10]/r}>1000*{[1-(1+5%)^10/(1+r)^10]/(r-5%)} 所以第一种情况分十次等分支付更好。 4、是,因为名义利率通常不提供相关利率。唯一的优势就是方便 计算,但是随着现在计算机设备的发展,这种优势已经不明显。 5、新生将收到更多的津贴。因为新生到偿还贷款的时间较长。 6、因为货币具有时间价值。GMAC当期获得五百美元的使用权, 如果投资得当,三十年后的收益将会高于一千美元。 7、除非出现通货紧缩,资金成本成为负值,否则GMAC有权利在 任意时候以10000美元的价格赎回该债券,都会增加投资者的持有该债券的意愿。 8、我不愿意今天支付五百美元来换取三十年后的一万美元。关键 因素:一是同类投资相比的回报率是否较高,二是投资的回报率和风险是否相匹配。回答取决于承诺偿还人,因为必须评估其三十年后存续的风险。 9、财政部的债券价格应该更高,因为财政部发行债券是以国家信

用为担保,违约风险最小,基本可视为无风险债券。 10、应该超过。因为货币具有时间价值,债券的价格会随着时间的 发展逐渐上升,最终达到一万美元。所以2010年,债券的价格 应该会更高。但是这具有很大的不确定性,因为宏观经济环境 和公司微观环境会发生变化,都有可能造成债券价格发生变化。 11、 a 1000*(1+6%)^10=1791美元 b 1000*(1+9%)^10=1967美元 c 1000*(1+6%)^20=3207美元 d 因为在按照复利计算时,不仅本金会产生利息,本金的利息 也会产生利息。 12、PV=FV/(1+r)^t=7.5/(1+8.2%)^20=1.55亿美元 13、PV=C/r=120/5.7%=2105美元 14、FV=C*e^(rT) a FV=1900*e^(12%*5)=1900*1.8221=3462美元 b FV=1900*e^(10%*3)=1900*1.3499=2565美元 c FV=1900*e^(5%*10)=1900*1.6487=3133美元 d FV=1900*e^(7%*8)=1900*1.7507=3326美元 15、有限年限支付下PV= C*{[1-1/(1+r)^T]/r} 当T=15时, PV=4300*{[1-1/(1+9%)^15]/9%}=4300*8.0607=34661美元 当T=40时, PV=4300*{[1-1/(1+9%)^40]/9%}=4300*10.7574=46257美元

to abandon, and timing options. 4. Decision trees represent an approach for valuing projects with these hidden, or real, options. Concept Questions 1. Forecasting Risk What is forecasting risk? In general, would the degree of forecasting risk be greater for a new product or a cost-cutting proposal? Why? 2. Sensitivity Analysis and Scenario Analysis What is the essential difference between sensitivity analysis and scenario analysis? 3. Marginal Cash Flows A coworker claims that looking at all this marginal this and incremental that is just a bunch of nonsense, and states, “Listen, if our average revenue doesn’t exceed our average cost, then we will have a negative cash flow, and we will go broke!” How do you respond? 4. Break-Even Point As a shareholder of a firm that is contemplating a new project, would you be more concerned with the accounting break-even point, the cash break-even point (the point at which operating cash flow is zero), or the financial break-even point? Why? 5. Break-Even Point Assume a firm is considering a new project that requires an initial investment and has equal sales and costs over its life. Will the project reach the accounting, cash, or financial break-even point first? Which will it reach next? Last? Will this order always apply? 6. Real Options Why does traditional NPV analysis tend to underestimate the true value of a capital budgeting project? 7. Real Options The Mango Republic has just liberalized its markets and is now permitting foreign investors. Tesla Manufacturing has analyzed starting a project in the country and has determined that the project has a negative NPV. Why might the company go ahead with the project? What type of option is most likely to add value to this project? 8. Sensitivity Analysis and Breakeven How does sensitivity analysis interact with break-even analysis? 9. Option to Wait An option can often have more than one source of value. Consider a logging company. The company can log the timber today or wait another year (or more) to log the timber. What advantages would waiting one year potentially have? 10. Project Analysis You are discussing a project analysis with a coworker. The project involves real options, such as expanding the project if successful, or abandoning the project if it fails. Your coworker makes the following statement: “This analysis is ridiculous. We looked at expanding or abandoning the project in two years, but there are many other options we should consider. For example, we could expand in one year, and expand further in two years. Or we could expand in one year, and abandon the project in two years. There are too many options for us to examine. Because of this, anything this analysis would give us is worthless.” How would you evaluate this statement? Considering that with any capital budgeting project there are an infinite number of real options, when do you stop the option analysis on an individual project? Questions and Problems: connect? BASIC (Questions 1–10) 1. Sensitivity Analysis and Break-Even Point We are evaluating a project that costs $724,000, has an eight-year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 75,000 units per year. Price per unit is $39, variable cost per unit is $23, and fixed costs are $850,000 per year. The tax rate is 35 percent, and we require a 15 percent return on this project. 1. Calculate the accounting break-even point.

第六章:投资决策 1.机会成本是指进行一项投资时放弃另一项投资所承担的成本。选择投资和放弃投资之间的收益差是可能获取收益的成本。 2. (1)新的投资项目所来的公司其他产品的销售下滑属于副效应中的侵蚀效应,应被归为增量现金流。 (2)投入建造的机器和厂房属于新生产线的成本,应被归为增量现金流。(3)过去3 年发生的和新项目相关的研发费用属于沉没成本,不应被归为增量现金流。 (4)尽管折旧不是现金支出,对现金流量产生直接影响,但它会减少公司的净收入,并且减低公司的税收,因此应被归为增量现金流。 (5)公司发不发放股利与投不投资某一项目的决定无关,因此不应被归为增量现金流。 (6)厂房和机器设备的销售收入是一笔现金流入,因此应被归为增量现金流。(7)需要支付的员工薪水与医疗保险费用应被包括在项目成本里,因此应被归为增量现金流。 3. 第一项因为会产生机会成本,所以会产生增量现金流;第二项因为会产生副效应中的侵蚀效应,所以会会产生增量现金流;第三项属于沉没成本,不会 产生增量现金流。 4. 为了避免税收,公司可能会选择MACRS,因为该折旧法在早期有更大的折旧额,这样可以减免赋税,并且没有任何现金流方面的影响。但需要注意的是直线折旧法与MACRS 的选择只是时间价值的问题,两者的折旧是相等的,只是时间不同。 5. 这只是一个简单的假设。因为流动负债可以全部付清,流动资产却不可能全部以现金支付,存货也不可能全部售完。 6. 这个说法是可以接受的。因为某一个项目可以用权益来融资,另一个项目可以用债务来融资,而公司的总资本结构不会发生变化。根据MM 定理,融资成本与项目的增量现金流量分析无关。 7. ECA 方法在分析具有不同生命周期的互斥项目的情况下比较适应,这是因为ECA 方法可以使得互斥项目具有相同的生命周期,这样就可以进行比较。ECA 方法在假设项目现金流相同这一点与现实生活不符,它忽略了通货膨胀率以及不断变更的经济环境。 8. 折旧是非付现费用,但它可以在收入项目中减免赋税,这样折旧将使得实际现金流出的赋税减少一定额度,并以此影响项目现金流,因此,折旧减免赋税的效应应该被归为总的增量税后现金流。 9. 应考虑两个方面:第一个是侵蚀效应,新书是否会使得现有的教材销售额下降?第二个是竞争,是否其他出版商会进入市场并出版类似书籍?如果是的话,侵蚀效应将会降低。出版商的主要需要考虑出版新书带来的协同效应是否大于侵蚀效应,如果大于,则应该出版新书,反之,则放弃。 10. 当然应该考虑,是否会对保时捷的品牌效应产生破坏是公司应该考虑到的。如果品牌效应被破坏,汽车销量将受到一定影响。 11. 保时捷可能有更低的边际成本或是好的市场营销。当然,也有可能是一个决策失误。 12. 保时捷将会意识到随着越来越多产品投入市场,竞争越来越激烈,过高的利润会减少。

reported in the financing activity section of the accounting statement of cash flows. When Tyco received payments from customers, the cash inflows were reported as operating cash flows. Another method used by Tyco was to have acquired companies prepay operating expenses. In other words, the company acquired by Tyco would pay vendors for items not yet received. In one case, the payments totaled more than $50 million. When the acquired company was consolidated with Tyco, the prepayments reduced Tyco’s cash outflows, thus increasing the operating cash flows. Dynegy, the energy giant, was accused of engaging in a number of complex “round-trip trades.” The round-trip trades essentially involved the sale of natural resources to a counterparty, with the repurchase of the resources from the same party at the same price. In essence, Dynegy would sell an asset for $100, and immediately repurchase it from the buyer for $100. The problem arose with the treatment of the cash flows from the sale. Dynegy treated the cash from the sale of the asset as an operating cash flow, but classified the repurchase as an investing cash outflow. The total cash flows of the contracts traded by Dynegy in these round-trip trades totaled $300 million. Adelphia Communications was another company that apparently manipulated cash flows. In Adelphia’s case, the company capitalized the labor required to install cable. In other words, the company classified this labor expense as a fixed asset. While this practice is fairly common in the telecommunications industry, Adelphia capitalized a higher percentage of labor than is common. The effect of this classification was that the labor was treated as an investment cash flow, which increased the operating cash flow. In each of these examples, the companies were trying to boost operating cash flows by shifting cash flows to a different heading. The important thing to notice is that these movements don’t affect the total cash flow of the firm, which is why we recommend focusing on this number, not just operating cash flow.
