1、原文：Foundations of economic value addedThe EVA RevolutionIn a market-driven economy many companies will create wealth .Other firms however will undoubtedly destroy it. Discovering those economic factors that lead to wealth creation and destruction among companies is important to many constituencies,

2、not the least of which is corporate officials and investment managers. For corporate managers, wealth creation is fundamental to the economic survival of the firm. Managers that fail (or refuse) to see the importance of this imperative in an open economy do so at the peril of the organization and th

3、eir career.Finding the “best” companies and industries in marketplace is of primary importance to investment managers. With the proper financial tools, portfolio managers may be able to enhance their active performance over-and-above the returns available on similar risk indexed passive strategies.

4、A new analytical tool called EVA is now assisting this wealth-discovery and company-selection process .The innovative changes that this financial metric have spawned in the twin areas of corporate finance and investment management is the driving force behind what can be formerly called the “EVA revo

5、lution”.EVA in practiceThe analytical tool called EVA ,for Economic Value Added, was commercially developed in 1982 by the corporate advisory team of Joel Stern and G.BennettStewart .This financial metic gained early acceptance from the corporate community because of its innovative way of looking at

6、 the firms real profitability ,unlike traditional measures of profitsuch as EBIT ,EBITDA ,and net operating incomeEVA looks at the firms “residual profitability”, net of both the direct cost of debt capital and the indirect cost of equity capital. In this way ,EVA serves as a modern-day measure of c

7、orporate success because it is closely aligned with the shareholder wealth-maximization requirement.Large firms like Coca Coca ,Diagea ,Lilly(Eli) ,Guidant ,and SPX have used EVA as a guide to creating economic value for their shareholders .Bonuses and incentive pay schemes at these firms have been

8、built around the managers ability (or lack thereof) to generate positive EVA within the firms operating divisions .Positive payments accrue to managers having divisional operating profits that on balance exceed the relevant “cost of capital”, while negative incentive payments may occur if the larger

9、-term divisional operating profits fall short of the overall capital costs .Thus ,by a accounting for both the cost of debt and equity capital ,EVA gives managers the incentive to act like shareholders when making corporate investment decisions.EVA is also gaining popularity in the investment commun

10、ity .The June 1996 conference on “Economic Value Added” at CS First Boston and the “roll out” of Goldman Sachs EVA research platform in May 1997 is testimony to this exciting development .Indeed , “buy side” investment firms like Global Asset Management and Oppenheimer Capital use EVA in their stock

11、 selection ,portfolio construction ,and risk control processes .Other large investment firms are taking a serious look ,and EVA is also making meaningful inroads in world of global performance analytics . Moreover ,recent empirical studies in the Journal Portfolio Management(among other finance and

12、investment journals)shows that EVA is being advanced in both the academic and financial communities.Evolution of EVAThe evolution of economic profiteconomic value added(EVA)is a fascinating study with historical roots that can be traced back to the classical economists notion of “residual income.”Fo

13、r instance ,consider the definition of economic profit made in 1890 by famous British economist ,Alfred Marshall , regrading the real meaning of a business owners profit: “What remains of his profits after deducting interest on his capital at the current rate may be called his earnings of undertakin

14、g or management.”Based on Marshalls statement ,it is evident that the economists definition of profitnamely ,a residual view of income or economic profitis radically different from the accounting measures of profit in use today ,such as EBIT ,EBITDA ,or net operating income .This is, a key distincti

15、on between economic profit and accounting profit lies in the classical economists notion that a company is not truly profitable unless its revenue have covered the usual production and operating expenses of running a business ,and provided a normal return on the owners invested capital .In a more fu

16、ndamental sense ,this residual view of income is really what todays economic profit movement is really all about.While EVA is rooted in classical economic theory ,three pioneering 20th century American economistsIrving Fisher during the 1930s,and Nobel Laureates Franco Modigliani and Merton Miller i

17、n the late 1950s to early 1960sexpanded upon the fuller meaning of economic profit in a corporate valuation context .Irving Fisher established a fundamental link between a companys net present value(NPV)and its discounted stream of expected cash flows .In turn ,Modigliani and Miller showed that corp

18、orate investment decisionsas manifest in positive NPV decisionsare the primary driver of a firms enterprise value and stock priceas opposed to the firms capital structure mix of debt and equity securities.Basically ,the theory of economic value added rests on two principle assertions:(1) a company i

19、s not truly profitable unless it earns a return on invested capital that exceeds the opportunity cost of capital and (2)that wealth is created when a firms managers make positive NPV investments decisions for the shareholders .What expand on these EVA tenets of wealth creation as we move forward in

20、this book .For now ,Lets look at operational definitions of EVA that have shaped the current economic profit movement as well as introduce the link between a companys economic profit and its market value added.Operational Definitions of EVAThere are two popular or operational ,ways of defining EVAna

21、mely ,an “accounting” way and a “finance” .From an accounting perspective ,EVA is defined as the difference between the firms net operating profit after tax(NOPAT)and its weighted-average dollar cost of capital .As a result ,EVA differs from traditional accounting measures of corporate profit includ

22、ing ,EBIT (earnings before interest and taxes),EBITDA(EBTT plus depreciation and amortization),net income ,and even NOPAT because it fully accounts for the firms overall capital costs .This analytical difference is important to the firms owners because the EVA metic is net of both the direct cost of

23、 debt capital and the indirect cost of equity capitalas reflected the shareholders required return on common stock.In this context , EVA can be expressed in more general terms as:EVA=NOPAT-$Cost of CapitalIn this expression, the firms dollar cost of capital is calculated by multiplying the percentag

24、e cost of capital by the amount of invested capital according to:$Cost of Capital= %Cost of Capital/100* CapitalIn turn, the percentage cost of capital is obtained by taking a “weighted average” of the firms after-tax cost of debt and equity capital as shown by: %Cost of Capital=Debt weight * % Afte

25、r-tax debt cost+ Equity weight * %Cost of equityEVA: The Finance InterpretationFrom a finance perspective, EVA is defined in terms of how it relates to the firms “market value added.” In this context, MVA (or NPV) is equal to the present value of the firms expected future EVA. Additionally, since MV

26、A is equal to the market value of the firm less the “book capital” employed in the business, it can easily be shown that EVA is related to the intrinsic value of the firm and its outstanding debt and equity securities. Stating these concepts in more formal terms yields the familiar value-based relat

27、ionship between the firms “market value.MVA and EVA: Growth Considerations The basic EVA and MVA linkage outlined above can also be extended to a multiperiod framework. Without getting into complicated pricing details here, one can use a “constant growth” EVA model to show the pricing importance of

28、both the firms near-term EVA outlook and its long-term EVA growth rate in determining overall corporate (or enterprise) valuation. In this “Gordon-like” model, the relationship between the firms MVA and its EVA outlook for the future is expressed as:MVA=EVA(1)/(COC-gEVA)In this expression, EVA(1) is

29、 the firms current EVA outlook (one-year ahead forecast), gEVA is the firms assessed long-term EVA growth rate, and COC is the familial weighted cost of debt and equity capital.The constant-growth EVA model shows that the firms market value added (MVA) is positively related to its near-term EVA outl

30、ook, as measured by EVA(1), as well as the firms assessed long-term EVA growth rate, gEVA. As shown, the firms MVA is also negatively related to any unanticipated changes in the weighed-average cost of (debt and equity) capital, COC. However, in view of modern day capital structure principles (a la

31、Miller-Modigliani), this “cost of capital” interpretation does not imply that the firms corporate debt policy has any meaningful impact on the valuation of the firm and its outstanding debt and equity shares.PREVIEW OF WEALTH CREATERSLets now take a preliminary look at the MVA and EVA relationship f

32、or major U.S. wealth creators and destroyers. The MVA and EVA characteristics for five large U.S. wealth creatorsincluding General Electric, Cisco Systems, Microsoft Corporation, Wal-Mart Stores, and Merckfor the 11-year period covering 1990 to 2000 are shown in Exhibits1.2 and 1.3. These large capi

33、talization companies were listed by Stern Stewart & Co. as the top-five U.S. wealth creators (based on MVA ranking) in their 2001 Performance Universe.Exhibit 1.2 shows that wealth creators like General Electric , Cisco Systems , and Merck have substantially positive MVA that grows rapidly over time

34、 . At year-end 2000,General Electrics net present value was $426,616 million, while Cisco Systems and Merck were reporting MVA values of $272,131 and $203,689 million, respectively. During the 11-year period spanning 1990 to 2000, General Electrics net present value was growing at a compound yearly

35、rate of nearly 34%. Moreover, over the 11-year reporting period, Ciscos MVA was actually growing at an annualized rate of 86%, while Merck was reporting a respectable average MVA growth rate of about 21%.Exhibit 1.2 also reveals that the MVA values for the top-five U.S. wealth creators declined most

36、ly from year-end 1990 to 2000. For example, General Electrics MVA declined by about $45,000 million (or $45 billion) while Cisco Systems and Wal-Mart each experienced MVA declines of around $76,000 million. Indeed, Microsofts MVA declined by a staggering $412,000 million from $629,470 to $217,235 mi

37、llion between 1999 and 2000. As with Cisco et al. , the MVA decline for Microsoft was due in part to the general slowdown in economic activityespecially in the technology and telecommunication industriesand thus the precipitous decline in the U.S stock market commencing in the first half of 2000. Ad

38、ditionally, Microsofts sharp decline in MVA was due to serious legal challenges from competitors arising from its alleged “bundling” of software with the Windows operating system.Exhibit1.3 shows the source of the positive net present value being generated by the five U.S. wealth creators shown in E

39、xhibit1.2. Specifically, this exhibit reveals that wealth creators like General Electric, Microsoft, and Merck have substantially positive MVA because their EVA is both positive and growing at a substantial rate over time. At $5,943 million, General Electrics 2000 EVA is not only positive, but it al

40、so grew by 25% over the 1990-2000 period. With MVA and EVA growth rates in the 20-30% range during this decade, the two exhibits suggest that General Electrics net present value largely “tracked” the diversified conglomerates ever-rising “economic value added.” Likewise, Microsofts ten-year EVA grow

41、th rate, at 39%, seems to have provided the necessary fuel for its abnormal MVA growth rate, at 40%.Exhibit1.2 Market Value Added: Top-Five Wealth Creators in Performance Universe:1990-2000Exhibit 1.3 Economic Value Added: Top-Five Wealth Creators in Performance Universe:1990-2000Exhibit1.3 also sho

42、ws that Cisco Systems had tremendous growth in its EVA up to 1998. During this period, the networking firms EVA grew from just $9 million in 1990 to $775 million in 1998. This represents an astonishing EVA growth rate of 90% that, in turn, is joined with Ciscos MVA growth rate of 100%. On the other

43、hand, Ciscos EVA peaked at $775 million in 1998, then declined to $182 million in 1999, and actually turned negative in 2000, at -$365 million. Interestingly, Cisco was apparently overvalued in 1999 as its MVA peaked at $348,442 during that year in the presence of its falling EVA. Cisco continued it

44、s MVA decline in 2000 with the major sell off in technology stocks to end the year at $272,131 million. Thus, taken together, the MVA and EVA relationships shown in Exhibits1.2 and 1.3 are not only beneficial in describing the financial characteristics of wealth creators, but exhibits like these can

46、受（或拒绝）承认在开放经济下这一原则的重要性对于组织机构和事业是十分危险的。对于投资者来说，在市场上寻找“最好”的公司和产业是头等重要的事。利用适当的财务工具，投资组合经理可能提高他们的营运能力，使得在引入相同风险的被动策略的情况下，其回报高于有效回报。现在，有一种叫做EVA的新的分析工具正在帮助企业发现财富。这一创新的改革使得这种财务指标被引入公司理财和投资管理这两个领域，这就推动了我们原来所谓的“EVA革命”的产生。EVA在实践中的应用这种被叫做EVA的分析工具，即经济增加值，在1982年被由JoelStern和GBennettStewart 组成的公司咨询团队提出，并在商业上得到发展。因

47、为这种财务指标以一种创新的方式看待企业的真正利益，所以它在早期就被社会团体所接受。不像传统的利润度量标准，例如EBIT、EBITDA和营业净利EVA着眼于公司扣除了债务资本的直接成本和权益资本的间接成本之后的“剩余收益”，就这样，因为EVA与股东财富最大化的要求保持一致，它成了当代衡量企业成功的指标。一些像Coca Coca,Diagea,Lilly(Eli),Guidant和SPX那样的大公司已经将EVA作为了为股东创造经济价值的一个指标。在这些公司里，奖金和工资的激励机制迎合了管理者的能力（或缺乏能力），使得公司的经营部门形成正向的经济增加值。积极地薪酬管理归功于经营者拥有区域性的经营利润

48、，该利润总的来说超过了有关的“资本成本”，然而，消极的奖金可能引起长期的各地区的经营利润低于全部的资本成本。因此，通过对负债成本和权益资本进行计算，EVA给了经营者一个能像股东一样做出公司的投资决策的机会。EVA在投资团体中也很受欢迎。1996年6月在第一波士顿召开的“经济附加值”会议和1997年5月高盛投资公司关于EVA研究的讲座证明了这一人可喜的发展。的确，一些华尔街的慈善机构例如环球资产管理公司和奥本海默资本公司将EVA用于选股、投资组合构建和风险控制程序。另外一些大的投资公司开始进行认真的研究，并且指出EVA对于全球绩效分析有着重要的意义。此外，近期在投资组合管理杂志（在财经和投资期刊

49、中较有名）上的实证研究表明了EVA在学术界和财经界的进步。EVA的进化论经济利润的演变经济增加值（EVA）是一项拥有历史根源的、令人着迷的研究，它可以追溯到古典经济学家关于“剩余收益”的概念。例如，考虑到1890年，英国著名的经济学家AlfredMarshall提出的经济利益的概念，他重新定义了企业所有者获得的利润的真正含义：“剩余的收入扣除在当期利率下资本的利息才是他经营管理所得的收入。”以Mashall的理论为基础，显然，经济学家对于利润的定义换句话说，收入或经济利润剩余价值的观点与现在使用的会计计量利润的方法在根本上存在很大的差异，比如EBIT、EBITDA、或者营业净利。这就是经济利润和会计利润之间最主要的差别，原因在于古典经济学家认为，除非公司的收益超过了经营企业日常的生产和经营费用，并且投资资金有一个正常的回报，否则公司并不是真正有利可图的。在一个更基本的理论当中，
