1 Preface Let me begin this preface with a confession of a few of my own biases. First, I believe that theory and the models that flow from it should provide the tools to understand, analyze, and solve problems. The test of a model or theory then should not be based on its elegance but on its usefulness in problem solving. Second, there is little in corporate financial theory that is new and revolutionary. The core principles of corporate finance are common sense and have changed little over time. That should not be surprising. Corporate finance is only a few decades old, and people have been running businesses for thousands of years; it would be exceedingly presumptuous of us to believe that they were in the dark until corporate finance theorists came along and told them what to do. To be fair, it is true that corporate financial theory has made advances in taking commonsense principles and providing structure, but these advances have been primarily on the details. The story line in corporate finance has remained remarkably consistent over time. Talking about story lines allows me to set the first theme of this book. This book tells a story, which essentially summarizes the corporate finance view of the world. It classifies all decisions made by any business into three groups—decisions on where to invest the resources or funds that the business has raised, either internally or externally (the investment decision), decisions on where and how to raise funds to finance these investments (the financing decision), and decisions on how much and in what form to return funds back to the owners (the dividend decision). As I see it, the first principles of corporate finance can be summarized in Figure 1, which also lays out a site map for the book. Every section of this book relates to some part of this picture, and each chapter is introduced with it, with emphasis on that portion that will be analyzed in that chapter. (Note the chapter numbers below each section). Put another way, there are no sections of this book that are not traceable to this framework. 2 Figure 1 Corporate Finance: First Principles As you look at the chapter outline for the book, you are probably wondering where the chapters on present value, option pricing, and bond pricing are, as well as the chapters on short-term financial management, working capital, and international finance. The first set of chapters, which I would classify as “tools” chapters, are now contained in the appendices, and I relegated them there not because I think that they are unimportant but because I want the focus to stay on the story line. It is important that we understand the concept of time value of money, but only in the context of measuring returns on investments better and valuing business. Option pricing theory is elegant and provides impressive insights, but only in the context of looking at options embedded in projects and financing instruments like convertible bonds. The second set of chapters I excluded for a very different reason. As I see it, the basic principles of whether and how much you should invest in inventory, or how generous your credit terms should be, are no different than the basic principles that would apply if you were building a plant or buying equipment or opening a new store. Put 3 another way, there is no logical basis for the differentiation between investments in the latter (which in most corporate finance books is covered in the capital budgeting chapters) and the former (which are considered in the working capital chapters). You should invest in either if and only if the returns from the investment exceed the hurdle rate from the investment; the fact the one is short-term and the other is long-term is irrelevant. The same thing can be said about international finance. Should the investment or financing principles be different just because a company is considering an investment in Thailand and the cash flows are in Thai baht instead of in the United States, where the cash flows are in dollars? I do not believe so, and in my view separating the decisions only leaves readers with that impression. Finally, most corporate finance books that have chapters on small firm management and private firm management use them to illustrate the differences between these firms and the more conventional large publicly traded firms used in the other chapters. Although such differences exist, the commonalities between different types of firms vastly overwhelm the differences, providing a testimonial to the internal consistency of corporate finance. In summary, the second theme of this book is the emphasis on the universality of corporate financial principles across different firms, in different markets, and across different types of decisions. The way I have tried to bring this universality to life is by using five firms through the book to illustrate each concept; they include a large, publicly traded U.S. corporation (Disney); a small, emerging market commodity company (Aracruz Celulose, a Brazilian paper and pulp company); an Indian manufacturing company that is part of a family group (Tata Chemicals), a financial service firm (Deutsche Bank); and a small private business (Bookscape, an independent New York City bookstore). Although the notion of using real companies to illustrate theory is neither novel nor revolutionary, there are, two key differences in the way they are used in this book. First, these companies are analyzed on every aspect of corporate finance introduced here, rather than just selectively in some chapters. Consequently, the reader can see for him- or herself the similarities and the differences in the way investment, financing, and dividend principles are applied to four very different firms. Second, I do 4 not consider this to be a book where applications are used to illustrate theory but a book where the theory is presented as a companion to the illustrations. In fact, reverting back to my earlier analogy of theory providing the tools for understanding problems, this is a book where the problem solving takes center stage and the tools stay in the background. Reading through the theory and the applications can be instructive and even interesting, but there is no substitute for actually trying things out to bring home both the strengths and weaknesses of corporate finance. There are several ways I have made this book a tool for active learning. One is to introduce concept questions at regular intervals that invite responses from the reader. As an example, consider the following illustration from Chapter 7: 7.2. The Effects of Diversification on Venture Capitalist You are comparing the required returns of two venture capitalists who are interested in investing in the same software firm. One has all of his capital invested in only software firms, whereas the other has invested her capital in small companies in a variety of businesses. Which of these two will have the higher required rate of return? ❒ The venture capitalist who is invested only in software companies. ❒ The venture capitalist who is invested in a variety of businesses. ❒ Cannot answer without more information. This question is designed to check on a concept introduced in an earlier chapter on risk and return on the difference between risk that can be eliminated by holding a diversified portfolio and risk that cannot and then connecting it to the question of how a business seeking funds from a venture capitalist might be affected by this perception of risk. The answer to this question in turn will expose the reader to more questions about whether venture capital in the future will be provided by diversified funds and what a specialized venture capitalist (who invests in one sector alone) might need to do to survive in such an environment. This will allow readers to see what, for me at least, is one of the most exciting aspects of corporate finance—its capacity to provide a 5 framework that can be used to make sense of the events that occur around us every day and make reasonable forecasts about future directions. The second active experience in this book is found in the Live Case Studies at the end of each chapter. These case studies essentially take the concepts introduced in the chapter and provide a framework for applying them to any company the reader chooses. Guidelines on where to get the information to answer the questions are also provided. Although corporate finance provides an internally consistent and straightforward template for the analysis of any firm, information is clearly the lubricant that allows us to do the analysis. There are three steps in the information process— acquiring the information, filtering what is useful from what is not, and keeping the information updated. Accepting the limitations of the printed page on all of these aspects, I have put the power of online information to use in several ways. 1. The case studies that require the information are accompanied by links to Web sites that carry this information. 2. The data sets that are difficult to get from the Internet or are specific to this book, such as the updated versions of the tables, are available on my own Web site (www.damodaran.com) and are integrated into the book. As an example, the table that contains the dividend yields and payout ratios by industry sectors for the most recent quarter is referenced in Chapter 9 as follows: There is a data set online that summarizes dividend yields and payout ratios for U.S. companies, categorized by sector. You can get to this table by going to the website for the book and checking for datasets under chapter 9. 3. The spreadsheets used to analyze the firms in the book are also available on my Web site and are referenced in the book. For instance, the spreadsheet used to estimate the optimal debt ratio for Disney in Chapter 8 is referenced as follows: 6 Capstru.xls : This spreadsheet allows you to compute the optimal debt ratio firm value for any firm, using the same information used for Disney. It has updated interest coverage ratios and spreads built in. As with the dataset listing above, you can get this spreadsheet by going to the website for the book and checking under spreadsheets under chapter 8. For those of you have read the first two editions of this book, much of what I have said in this preface should be familiar. But there are three places where you will find this book to be different: a. For better or worse, the banking and market crisis of 2008 has left lasting wounds on our psyches as investors and shaken some of our core beliefs in how to estimate key numbers and approach fundamental trade offs. I have tried to adapt some of what I have learned about equity risk premiums and the distress costs of debt into the discussion. b. I have always been skeptical about behavioral finance but I think that the area has some very interesting insights on how managers behave that we ignore at our own peril. I have made my first foray into incorporating some of the work in behavioral financing into investing, financing and dividend decisions. As I set out to write this book, I had two objectives in mind. One was to write a book that not only reflects the way I teach corporate finance in a classroom but, more important, conveys the fascination and enjoyment I get out of the subject matter. The second was to write a book for practitioners that students would find useful, rather than the other way around. I do not know whether I have fully accomplished either objective, but I do know I had an immense amount of fun trying. I hope you do, too! 1.1 1 CHAPTER 1 THE FOUNDATIONS It’s all corporate finance. My unbiased view of the world Every decision made in a business has financial implications, and any decision that involves the use of money is a corporate financial decision. Defined broadly, everything that a business does fits under the rubric of corporate finance. It is, in fact, unfortunate that we even call the subject corporate finance, because it suggests to many observers a focus on how large corporations make financial decisions and seems to exclude small and private businesses from its purview. A more appropriate title for this book would be Business Finance, because the basic principles remain the same, whether one looks at large, publicly traded firms or small, privately run businesses. All businesses have to invest their resources wisely, find the right kind and mix of financing to fund these investments, and return cash to the owners if there are not enough good investments. In this chapter, we will lay the foundation for the rest of the book by listing the three fundamental principles that underlie corporate finance—the investment, financing, and dividend principles—and the objective of firm value maximization that is at the heart of corporate financial theory. The Firm: Structural Set-Up In the chapters that follow, we will use firm generically to refer to any business, large or small, manufacturing or service, private or public. Thus, a corner grocery store and Microsoft are both firms. The firm’s investments are generically termed assets. Although assets are often categorized by accountants into fixed assets, which are long-lived, and current assets, which are short-term, we prefer a different categorization. The assets that the firm has already invested in are called assets in place, whereas those assets that the firm is 1.2 2 expected to invest in the future are called growth assets. Though it may seem strange that a firm can get value from investments it has not made yet, high-growth firms get the bulk of their value from these yet-to-be-made investments. To finance these assets, the firm can raise money from two sources. It can raise funds from investors or financial institutions by promising investors a fixed claim (interest payments) on the cash flows generated by the assets, with a limited or no role in the day-to-day running of the business. We categorize this type of financing to be debt. Alternatively, it can offer a residual claim on the cash flows (i.e., investors can get what is left over after the interest payments have been made) and a much greater role in the operation of the business. We call this equity. Note that these definitions are general enough to cover both private firms, where debt may take the form of bank loans and equity is the owner’s own money, as well as publicly traded companies, where the firm may issue bonds (to raise debt) and common stock (to raise equity). Thus, at this stage, we can lay out the financial balance sheet of a firm as follows: We will return this framework repeatedly through this book. First Principles Every discipline has first principles that govern and guide everything that gets done within it. All of corporate finance is built on three principles, which we will call, rather unimaginatively, the investment principle, the financing principle, and the dividend principle. The investment principle determines where businesses invest their resources, the financing principle governs the mix of funding used to fund these investments, and the dividend principle answers the question of how much earnings should be reinvested back into the business and how much returned to the owners of the business. These core corporate finance principles can be stated as follows: 1.3 3 • The Investment Principle: Invest in assets and projects that yield a return greater than the minimum acceptable hurdle rate. The hurdle rate should be higher for riskier projects and should reflect the financing mix used—owners’ funds (equity) or borrowed money (debt). Returns on projects should be measured based on cash flows generated and the timing of these cash flows; they should also consider both positive and negative side effects of these projects. • The Financing Principle: Choose a financing mix (debt and equity) that maximizes the value of the investments made and match the financing to the nature of the assets being financed. • The Dividend Principle: If there are not enough investments that earn the hurdle rate, return the cash to the owners of the business. In the case of a publicly traded firm, the form of the return—dividends or stock buybacks—will depend on what stockholders prefer. When making investment, financing and dividend decisions, corporate finance is single-minded about the ultimate objective, which is assumed to be maximizing the value of the business. These first principles provide the basis from which we will extract the numerous models and theories that comprise modern corporate finance, but they are also commonsense principles. It is incredible conceit on our part to assume that until corporate finance was developed as a coherent discipline starting just a few decades ago, people who ran businesses made decisions randomly with no principles to govern their thinking. Good businesspeople through the ages have always recognized the importance of these first principles and adhered to them, albeit in intuitive ways. In fact, one of the ironies of recent times is that many managers at large and presumably sophisticated firms with access to the latest corporate finance technology have lost sight of these basic principles. The Objective of the Firm No discipline can develop cohesively over time without a unifying objective. The growth of corporate financial theory can be traced to its choice of a single objective and the development of models built around this objective. The objective in conventional corporate financial theory when making decisions is to maximize the value of the business or firm. Consequently, any decision (investment, financial, or dividend) that 1.4 4 increases the value of a business is considered a good one, whereas one that reduces firm value is considered a poor one. Although the choice of a singular objective has provided corporate finance with a unifying theme and internal consistency, it comes at a cost. To the degree that one buys into this objective, much of what corporate financial theory posits makes sense. To the degree that this objective is flawed, however, it can be argued that the theory built on it is flawed as well. Many of the disagreements between corporate financial theorists and others (academics as well as practitioners) can be traced to fundamentally different views about the correct objective for a business. For instance, there are some critics of corporate finance who argue that firms should have multiple objectives where a variety of interests (stockholders, labor, customers) are met, and there are others who would have firms focus on what they view as simpler and more direct objectives, such as market share or profitability. Given the significance of this objective for both the development and the applicability of corporate financial theory, it is important that we examine it much more carefully and address some of the very real concerns and criticisms it has garnered: It assumes that what stockholders do in their own self-interest is also in the best interests of the firm, it is sometimes dependent on the existence of efficient markets, and it is often blind to the social costs associated with value maximization. In the next chapter, we consider these and other issues and compare firm value maximization to alternative objectives. The Investment Principle Firms have scarce resources that must be allocated among competing needs. The first and foremost function of corporate financial theory is to provide a framework for firms to make this decision wisely. Accordingly, we define investment decisions to include not only those that create revenues and profits (such as introducing a new product line or expanding into a new market) but also those that save money (such as building a new and more efficient distribution system). Furthermore, we argue that decisions about how much and what inventory to maintain and whether and how much credit to grant to customers that are Hurdle Rate: A hurdle rate is a minimum acceptable rate of return for investing resources in a new investment. 1.5 5 traditionally categorized as working capital decisions, are ultimately investment decisions as well. At the other end of the spectrum, broad strategic decisions regarding which markets to enter and the acquisitions of other companies can also be considered investment decisions. Corporate finance attempts to measure the return on a proposed investment decision and compare it to a minimum acceptable hurdle rate to decide whether the project is acceptable. The hurdle rate has to be set higher for riskier projects and has to reflect the financing mix used, i.e., the owner’s funds (equity) or borrowed money (debt). In Chapter 3, we begin this process by defining risk and developing a procedure for measuring risk. In Chapter 4, we go about converting this risk measure into a hurdle rate, i.e., a minimum acceptable rate of return, both for entire businesses and for individual investments. Having established the hurdle rate, we turn our attention to measuring the returns on an investment. In Chapter 5 we evaluate three alternative ways of measuring returns— conventional accounting earnings, cash flows, and time-weighted cash flows (where we consider both how large the cash flows are and when they are anticipated to come in). In Chapter 6 we consider some of the potential side costs that might not be captured in any of these measures, including costs that may be created for existing investments by taking a new investment, and side benefits, such as options to enter new markets and to expand product lines that may be embedded in new investments, and synergies, especially when the new investment is the acquisition of another firm. The Financing Principle Every business, no matter how large and complex, is ultimately funded with a mix of borrowed money (debt) and owner’s funds (equity). With a publicly trade firm, debt may take the form of bonds and equity is usually common stock. In a private business, debt is more likely to be bank loans and an owner’s savings represent equity. Though we consider the existing mix of debt and equity and its implications for the minimum acceptable hurdle rate as part of the investment principle, we throw open the question of whether the existing mix is the right one in the financing principle section. There might be regulatory and other real-world constraints on the financing mix that a business can 1.6 6 use, but there is ample room for flexibility within these constraints. We begin this section in Chapter 7, by looking at the range of choices that exist for both private businesses and publicly traded firms between debt and equity. We then turn to the question of whether the existing mix of financing used by a business is optimal, given the objective function of maximizing firm value, in Chapter 8. Although the trade-off between the benefits and costs of borrowing are established in qualitative terms first, we also look at quantitative approaches to arriving at the optimal mix in Chapter 8. In the first approach, we examine the specific conditions under which the optimal financing mix is the one that minimizes the minimum acceptable hurdle rate. In the second approach, we look at the effects on firm value of changing the financing mix. When the optimal financing mix is different from the existing one, we map out the best ways of getting from where we are (the current mix) to where we would like to be (the optimal) in Chapter 9, keeping in mind the investment opportunities that the firm has and the need for timely responses, either because the firm is a takeover target or under threat of bankruptcy. Having outlined the optimal financing mix, we turn our attention to the type of financing a business should use, such as whether it should be long-term or short-term, whether the payments on the financing should be fixed or variable, and if variable, what it should be a function of. Using a basic proposition that a firm will minimize its risk from financing and maximize its capacity to use borrowed funds if it can match up the cash flows on the debt to the cash flows on the assets being financed, we design the perfect financing instrument for a firm. We then add additional considerations relating to taxes and external monitors (equity research analysts and ratings agencies) and arrive at strong conclusions about the design of the financing. The Dividend Principle Most businesses would undoubtedly like to have unlimited investment opportunities that yield returns exceeding their hurdle rates, but all businesses grow and mature. As a consequence, every business that thrives reaches a stage in its life when the cash flows generated by existing investments is greater than the funds needed to take on good investments. At that point, this business has to figure out ways to return the excess cash to owners In private businesses, this may just involve the owner withdrawing a 1.7 7 portion of his or her funds from the business. In a publicly traded corporation, this will involve either paying dividends or buying back stock. Note that firms that choose not to return cash to owners will accumulate cash balances that grow over time. Thus, analyzing whether and how much cash should be returned to the owners of a firm is the equivalent of asking (and answering) the question of how much cash accumulated in a firm is too much cash. In Chapter 10, we introduce the basic trade-off that determines whether cash should be left in a business or taken out of it. For stockholders in publicly traded firms, we note that this decision is fundamentally one of whether they trust the managers of the firms with their cash, and much of this trust is based on how well these managers have invested funds in the past. In Chapter 11, we consider the options available to a firm to return assets to its owners—dividends, stock buybacks and spin-offs—and investigate how to pick between these options. Corporate Financial Decisions, Firm Value, and Equity Value If the objective function in corporate finance is to maximize firm value, it follows that firm value must be linked to the three corporate finance decisions outlined— investment, financing, and dividend decisions. The link between these decisions and firm value can be made by recognizing that the value of a firm is the present value of its expected cash flows, discounted back at a rate that reflects both the riskiness of the projects of the firm and the financing mix used to finance them. Investors form expectations about future cash flows based on observed current cash flows and expected future growth, which in turn depend on the quality of the firm’s projects (its investment decisions) and the amount reinvested back into the business (its dividend decisions). The financing decisions affect the value of a firm through both the discount rate and potentially through the expected cash flows. This neat formulation of value is put to the test by the interactions among the investment, financing, and dividend decisions and the conflicts of interest that arise between stockholders and lenders to the firm, on one hand, and stockholders and managers, on the other. We introduce the basic models available to value a firm and its equity in Chapter 12, and relate them back to management decisions on investment, 1.8 8 financial, and dividend policy. In the process, we examine the determinants of value and how firms can increase their value. A Real-World Focus The proliferation of news and information on real-world businesses making decisions every day suggests that we do not need to use hypothetical examples to illustrate the principles of corporate finance. We will use five businesses through this book to make our points about corporate financial policy: 1. Disney Corporation: Disney Corporation is a publicly traded firm with wide holdings in entertainment and media. Most people around the world recognize the Mickey Mouse logo and have heard about or visited a Disney theme park or seen some or all of the Disney animated classic movies, but it is a much more diversified corporation than most people realize. Disney’s holdings include cruise line, real estate (in the form of time shares and rental properties in Florida and South Carolina), television (Disney cable, ABC and ESPN), publications, movie studios (Miramax, Pixar and Disney) and consumer products. Disney will help illustrate the decisions that large multi-business and multinational corporations have to make as they are faced with the conventional corporate financial decisions—Where do we invest? How do we finance these investments? How much do we return to our stockholders? 2. Bookscape Books: This company is a privately owned independent bookstore in New York City, one of the few left after the invasion of the bookstore chains, such as Barnes and Noble and Borders. We will take Bookscape Books through the corporate financial decision-making process to illustrate some of the issues that come up when looking at small businesses with private owners. 3. Aracruz Celulose: Aracruz Celulose is a Brazilian firm that produces eucalyptus pulp and operates its own pulp mills, electrochemical plants, and port terminals. Although it markets its products around the world for manufacturing high-grade paper, we use it to illustrate some of the questions that have to be dealt with when analyzing a company that is highly dependent upon commodity prices – paper and pulp, in this instance, and operates in an environment where inflation is high and volatile and the economy itself is in transition. 1.9 9 4. Deutsche Bank: Deutsche Bank is the leading commercial bank in Germany and is also a leading player in investment banking. We will use Deutsche Bank to illustrate some of the issues the come up when a financial service firm has to make investment, financing and dividend decisions. Since banks are highly regulated institutions, it will also serve to illustrate the constraints and opportunities created by the regulatory framework. 5. Tata Chemicals: Tata Chemicals is a firm involved in the chemical and fertilizer business and is part of one of the largest Indian family group companies, the Tata Group, with holdings in technology, manufacturing and service businesses. In addition to allowing us to look at issues specific to manufacturing firms, Tata Chemicals will also give us an opportunity to examine how firms that are part of larger groups make corporate finance decisions. We will look at every aspect of finance through the eyes of all five companies, sometimes to draw contrasts between the companies, but more often to show how much they share. A Resource Guide To make the learning in this book as interactive and current as possible, we employ a variety of devices. This icon indicates that spreadsheet programs can be used to do some of the analysis that will be presented. For instance, there are spreadsheets that calculate the optimal financing mix for a firm as well as valuation spreadsheets. This symbol marks the second supporting device: updated data on some of the inputs that we need and use in our analysis that is available online for this book. Thus, when we estimate the risk parameters for firms, we will draw attention to the data set that is maintained online that reports average risk parameters by industry. At regular intervals, we will also ask readers to answer questions relating to a topic. These questions, which will generally be framed using real-world examples, will help emphasize the key points made in a chapter and will be marked with this icon. 1.10 10 ✄ .In each chapter, we will introduce a series of boxes titled “In Practice,” which will look at issues that are likely to come up in practice and ways of addressing these issues. We examine how firms behave when it comes to assessing risk, evaluating investments and determining the mix off debt and equity, and dividend policy. To make this assessment, we will look at both surveys of decision makers (which chronicle behavior at firms) as well as the findings from studies in behavioral finance that try to explain patterns of management behavior. Some Fundamental Propositions about Corporate Finance There are several fundamental arguments we will make repeatedly throughout this book. 1. Corporate finance has an internal consistency that flows from its choice of maximizing firm value as the only objective function and its dependence on a few bedrock principles: Risk has to be rewarded, cash flows matter more than accounting income, markets are not easily fooled, and every decision a firm makes has an effect on its value. 2. Corporate finance must be viewed as an integrated whole, rather than a collection of decisions. Investment decisions generally affect financing decisions and vice versa; financing decisions often influence dividend decisions and vice versa. Although there are circumstances under which these decisions may be independent of each other, this is seldom the case in practice. Accordingly, it is unlikely that firms that deal with their problems on a piecemeal basis will ever resolve these problems. For instance, a firm that takes poor investments may soon find itself with a dividend problem (with insufficient funds to pay dividends) and a financing problem (because the drop in earnings may make it difficult for them to meet interest expenses). 3. Corporate finance matters to everybody. There is a corporate financial aspect to almost every decision made by a business; though not everyone will find a use for all the components of corporate finance, everyone will find a use for at least some part of it. Marketing managers, corporate strategists, human resource managers, and information 1.11 11 technology managers all make corporate finance decisions every day and often don’t realize it. An understanding of corporate finance will help them make better decisions. 4. Corporate finance is fun. This may seem to be the tallest claim of all. After all, most people associate corporate finance with numbers, accounting statements, and hardheaded analyses. Although corporate finance is quantitative in its focus, there is a significant component of creative thinking involved in coming up with solutions to the financial problems businesses do encounter. It is no coincidence that financial markets remain breeding grounds for innovation and change. 5. The best way to learn corporate finance is by applying its models and theories to real- world problems. Although the theory that has been developed over the past few decades is impressive, the ultimate test of any theory is application. As we show in this book, much (if not all) of the theory can be applied to real companies and not just to abstract examples, though we have to compromise and make assumptions in the process. Conclusion This chapter establishes the first principles that govern corporate finance. The investment principle specifies that businesses invest only in projects that yield a return that exceeds the hurdle rate. The financing principle suggests that the right financing mix for a firm is one that maximizes the value of the investments made. The dividend principle requires that cash generated in excess of good project needs be returned to the owners. These principles are the core for what follows in this book. 2.1 1 CHAPTER 2 THE OBJECTIVE IN DECISION MAKING If you do not know where you are going, it does not matter how you get there. Anonymous Corporate finance’s greatest strength and greatest weakness is its focus on value maximization. By maintaining that focus, corporate finance preserves internal consistency and coherence and develops powerful models and theory about the right way to make investment, financing, and dividend decisions. It can be argued, however, that all of these conclusions are conditional on the acceptance of value maximization as the only objective in decision-making. In this chapter, we consider why we focus so strongly on value maximization and why, in practice, the focus shifts to stock price maximization. We also look at the assumptions needed for stock price maximization to be the right objective, what can go wrong with firms that focus on it, and at least partial fixes to some of these problems. We will argue strongly that even though stock price maximization is a flawed objective, it offers far more promise than alternative objectives because it is self-correcting. Choosing the Right Objective Let’s start with a description of what an objective is and the purpose it serves in developing theory. An objective specifies what a decision maker is trying to accomplish and by so doing provides measures that can be used to choose between alternatives. In most firms, the managers of the firm, rather than the owners, make the decisions about where to invest or how to raise funds for an investment. Thus, if stock price maximization is the objective, a manager choosing between two alternatives will choose the one that increases stock price more. In most cases, the objective is stated in terms of maximizing some function or variable, such as profits or growth, or minimizing some function or variable, such as risk or costs. So why do we need an objective, and if we do need one, why can’t we have several? Let’s start with the first question. If an objective is not chosen, there is no 2.2 2 systematic way to make the decisions that every business will be confronted with at some point in time. For instance, without an objective, how can Disney’s managers decide whether the investment in a new theme park is a good one? There would be a menu of approaches for picking projects, ranging from reasonable ones like maximizing return on investment to obscure ones like maximizing the size of the firm, and no statements could be made about their relative value. Consequently, three managers looking at the same project may come to three separate conclusions. If we choose multiple objectives, we are faced with a different problem. A theory developed around multiple objectives of equal weight will create quandaries when it comes to making decisions. For example, assume that a firm chooses as its objectives maximizing market share and maximizing current earnings. If a project increases market share and current earnings, the firm will face no problems, but what if the project under analysis increases market share while reducing current earnings? The firm should not invest in the project if the current earnings objective is considered, but it should invest in it based on the market share objective. If objectives are prioritized, we are faced with the same stark choices as in the choice of a single objective. Should the top priority be the maximization of current earnings or should it be maximizing market share? Because there is no gain, therefore, from having multiple objectives, and developing theory becomes much more difficult, we argue that there should be only one objective. There are a number of different objectives that a firm can choose between when it comes to decision making. How will we know whether the objective that we have chosen is the right objective? A good objective should have the following characteristics. a. It is clear and unambiguous. An ambiguous objective will lead to decision rules that vary from case to case and from decision maker to decision maker. Consider, for instance, a firm that specifies its objective to be increasing growth in the long term. This is an ambiguous objective because it does not answer at least two questions. The first is growth in what variable—Is it in revenue, operating earnings, net income, or earnings per share? The second is in the definition of the long term: Is it three years, five years, or a longer period? b. It comes with a timely measure that can be used to evaluate the success or failure of decisions. Objectives that sound good but don’t come with a measurement 2.3 3 mechanism are likely to fail. For instance, consider a retail firm that defines its objective as maximizing customer satisfaction. How exactly is customer satisfaction defined, and how is it to be measured? If no good mechanism exists for measuring how satisfied customers are with their purchases, not only will managers be unable to make decisions based on this objective but stockholders will also have no way of holding them accountable for any decisions they do make. c. It does not create costs for other entities or groups that erase firm-specific benefits and leave society worse off overall. As an example, assume that a tobacco company defines its objective to be revenue growth. Managers of this firm would then be inclined to increase advertising to teenagers, because it will increase sales. Doing so may create significant costs for society that overwhelm any benefits arising from the objective. Some may disagree with the inclusion of social costs and benefits and argue that a business only has a responsibility to its stockholders, not to society. This strikes us as shortsighted because the people who own and operate businesses are part of society. The Classical Objective There is general agreement, at least among corporate finance theorists that the objective when making decisions in a business is to maximize value. There is some disagreement on whether the objective is to maximize the value of the stockholder’s stake in the business or the value of the entire business (firm), which besides stockholders includes the other financial claim holders (debt holders, preferred stockholders, etc.). Furthermore, even among those who argue for stockholder wealth maximization, there is a question about whether this translates into maximizing the stock price. As we will see in this chapter, these objectives vary in terms of the assumptions needed to justify them. The least restrictive of the three objectives, in terms of assumptions needed, is to maximize the firm value, and the most restrictive is to maximize the stock price. Multiple Stakeholders and Conflicts of Interest In the modern corporation, stockholders hire managers to run the firm for them; these managers then borrow from banks and bondholders to finance the firm’s operations. 2.4 4 Investors in financial markets respond to information about the firm revealed to them by the managers, and firms have to operate in the context of a larger society. By focusing on maximizing stock price, corporate finance exposes itself to several risks. Each of these stakeholders has different objectives and there is the distinct possibility that there will be conflicts of interests among them. What is good for managers may not necessarily be good for stockholders, and what is good for stockholders may not be in the best interests of bondholders and what is beneficial to a firm may create large costs for society. These conflicts of interests are exacerbated further when we bring in two additional stakeholders in the firm. First, the employees of the firm may have little or no interest in stockholder wealth maximization and may have a much larger stake in improving wages, benefits, and job security. In some cases, these interests may be in direct conflict with stockholder wealth maximization. Second, the customers of the business will probably prefer that products and services be priced lower to maximize their utility, but again this may conflict with what stockholders would prefer. Potential Side Costs of Value Maximization As we noted at the beginning of this section, the objective in corporate finance can be stated broadly as maximizing the value of the entire business, more narrowly as maximizing the value of the equity stake in the business or even more narrowly as maximizing the stock price for a publicly traded firm. The potential side costs increase as the objective is narrowed. If the objective when making decisions is to maximize firm value, there is a possibility that what is good for the firm may not be good for society. In other words, decisions that are good for the firm, insofar as they increase value, may create social costs. If these costs are large, we can see society paying a high price for value maximization, and the objective will have to be modified to allow for these costs. To be fair, however, this is a problem that is likely to persist in any system of private enterprise and is not peculiar to value maximization. The objective of value maximization may also face obstacles when there is separation of ownership and management, as there is in most large public corporations. When managers act as agents for the owners (stockholders), there is the potential for a conflict of interest between stockholder and managerial 2.5 5 interests, which in turn can lead to decisions that make managers better off at the expense of stockholders. When the objective is stated in terms of stockholder wealth, the conflicting interests of stockholders and bondholders have to be reconciled. Since stockholders are the decision makers and bondholders are often not completely protected from the side effects of these decisions, one way of maximizing stockholder wealth is to take actions that expropriate wealth from the bondholders, even though such actions may reduce the wealth of the firm. Finally, when the objective is narrowed further to one of maximizing stock price, inefficiencies in the financial markets may lead to misallocation of resources and to bad decisions. For instance, if stock prices do not reflect the long-term consequences of decisions, but respond, as some critics say, to short-term earnings effects, a decision that increases stockholder wealth (which reflects long-term earnings potential) may reduce the stock price. Conversely, a decision that reduces stockholder wealth but increases earnings in the near term may increase the stock price. Why Corporate Finance Focuses on Stock Price Maximization Much of corporate financial theory is centered on stock price maximization as the sole objective when making decisions. This may seem surprising given the potential side costs just discussed, but there are three reasons for the focus on stock price maximization in traditional corporate finance. • Stock prices are the most observable of all measures that can be used to judge the performance of a publicly traded firm. Unlike earnings or sales, which are updated once every quarter or once every year, stock prices are updated constantly to reflect new information coming out about the firm. Thus, managers receive instantaneous feedback from investors on every action that they take. A good illustration is the response of markets to a firm announcing that it plans to acquire another firm. Although managers consistently paint a rosy picture of every acquisition that they plan, the stock price of the acquiring firm drops at the time of the announcement of the deal in roughly half of all acquisitions, suggesting that markets are much more skeptical about managerial claims. 2.6 6 • If investors are rational and markets are efficient, stock prices will reflect the long- term effects of decisions made by the firm. Unlike accounting measures like earnings or sales measures, such as market share, which look at the effects on current operations of decisions made by a firm, the value of a stock is a function of the long- term health and prospects of the firm. In a rational market, the stock price is an attempt on the part of investors to measure this value. Even if they err in their estimates, it can be argued that an erroneous estimate of long-term value is better than a precise estimate of current earnings. • Finally, choosing stock price maximization as an objective allows us to make categorical statements about the best way to pick projects and finance them and to test these statements with empirical observation. 2.1. : Which of the Following Assumptions Do You Need to Make for Stock Price Maximization to Be the Only Objective in Decision Making? a. Managers act in the best interests of stockholders. b. Lenders to the firm are fully protected from expropriation. c. Financial markets are efficient. d. There are no social costs. e. All of the above. f. None of the above In Practice: What Is the Objective in Decision Making in a Private Firm or a Nonprofit Organization? The objective of maximizing stock prices is a relevant objective only for firms that are publicly traded. How, then, can corporate finance principles be adapted for private firms? For firms that are not publicly traded, the objective in decision-making is the maximization of firm value. The investment, financing, and dividend principles we will develop in the chapters to come apply for both publicly traded firms, which focus on stock prices, and private businesses, which maximize firm value. Because firm value is not observable and has to be estimated, what private businesses will lack is the 2.7 7 feedback—sometimes unwelco
