Value investing

Value investing is an investment paradigm that derives from the ideas on investment and speculation that Ben Graham & David Dodd began teaching at Columbia Business School in 1928 and subsequently developed in their 1934 text Security Analysis. Although value investing has taken many forms since its inception, it generally involves buying securities whose shares appear underpriced by some form(s) of fundamental analysis.^[1] As examples, such securities may be stock in public companies that trade at discounts to book value or tangible book value, have high dividend yields, have low price-to-earning multiples or have low price-to-book ratios.

Notable proponents of value investing, including Berkshire Hathaway chairman Warren Buffett, have argued that the essence of value investing is buying stocks at less than their intrinsic value.^[2] The discount of the market price to the intrinsic value is what Benjamin Graham called the "margin of safety". The intrinsic value is the discounted value of all future distributions.

However, the future distributions and the appropriate discount rate can only be assumptions. Warren Buffett has taken the value investing concept even further as his thinking has evolved to where for the last 25 years or so his focus has been on "finding an outstanding company at a sensible price" rather than generic companies at a bargain price. This concept is important as you are actually buying into a business.

History

Benjamin Graham

Benjamin Graham

Value investing was established by Benjamin Graham and David Dodd, both professors at Columbia Business School and teachers of many famous investors. In Graham's book The Intelligent Investor, he advocated the important concept of margin of safety — first introduced in Security Analysis, a 1934 book he coauthored with David Dodd — which calls for a cautious approach to investing. In terms of picking stocks, he recommended defensive investment in stocks trading below their tangible book value as a safeguard to adverse future developments often encountered in the stock market.

[edit] Further evolution

However, the concept of value (as well as "book value") has evolved significantly since the 1970s. Book value is most useful in industries where most assets are tangible. Intangible assets such as patents, software, brands, or goodwill are difficult to quantify, and may not survive the break-up of a company. When an industry is going through fast technological advancements, the value of its assets is not easily estimated. Sometimes, the production power of an asset can be significantly reduced due to competitive disruptive innovation and therefore its value can suffer permanent impairment. One good example of decreasing asset value is a personal computer. An example of where book value does not mean much is the service and retail sectors. One modern model of calculating value is the discounted cash flow model (DCF). The value of an asset is the sum of its future cash flows, discounted back to the present.

Value Investing Performance

Performance, value strategies

Value investing has proven to be a successful investment strategy. There are several ways to evaluate its success. One way is to examine the performance of simple value strategies, such as buying low PE ratio stocks, low price-to-cash-flow ratio stocks, or low price-to-book ratio stocks. Numerous academics have published studies investigating the effects of buying value stocks. These studies have consistently found that value stocks outperform growth stocks and the market as a whole.^[3][4][5]

Performance, value investors

Another way to examine the performance of value investing strategies is to examine the investing performance of well-known value investors. Simply examining the performance of the best known value investors would not be instructive, because investors do not become well known unless they are successful. This introduces a selection bias. A better way to investigate the performance of a group of value investors was suggested by Warren Buffett, in his May 17, 1984 speech that was published as The Superinvestors of Graham-and-Doddsville. In this speech, Buffett examined the performance of those investors who worked at Graham-Newman Corporation and were thus most influenced by Benjamin Graham. Buffett's conclusion is identical to that of the academic research on simple value investing strategies--value investing is, on average, successful in the long run.

During about a 25-year period (1965-90), published research and articles in leading journals of the value ilk were few. Warren Buffett once commented, "You couldn't advance in a finance department in this country unless you thought that the world was flat."

Well Known Value Investors

Benjamin Graham is regarded by many to be the father of value investing. Along with David Dodd, he wrote Security Analysis, first published in 1934. The most lasting contribution of this book to the field of security analysis was to emphasize the quantifiable aspects of security analysis (such as the evaluations of earnings and book value) while minimizing the importance of more qualitative factors such as the quality of a company's management. Graham later wrote The Intelligent Investor, a book that brought value investing to individual investors. Aside from Buffett, many of Graham's other students, such as William J. Ruane, Irving Kahn and Charles Brandes have gone on to become successful investors in their own right.

Graham's most famous student, however, was Warren Buffett, who ran successful investing partnerships before closing them in 1969 to focus on running Berkshire Hathaway. Charlie Munger joined Buffett at Berkshire Hathaway in the 1970s and has since worked as Vice Chairman of the company. Buffett has credited Munger with encouraging him to focus on long-term sustainable growth rather than on simply the valuation of current cash flows or assets

Another famous value investor is John Templeton. He first achieved investing success by buying shares of a number of companies in the aftermath of the stock market crash of 1929.

Martin J. Whitman is another well-regarded value investor. His approach is called safe-and-cheap, which was hitherto referred to as financial-integrity approach. Martin Whitman focuses on acquiring common shares of companies with extremely strong financial position at a price reflecting meaningful discount to the estimated NAV of the company concerned. Martin Whitman believes it is ill-advised for investors to pay much attention to the trend of macro-factors (like employment, movement of interest rate, GDP, etc.) not so much because they are not important as because attempts to predict their movement are almost always futile. Martin Whitman's letters to shareholders of his Third Avenue Value Fund (TAVF) are considered valuable resources "for investors to pirate good ideas" by another famous investor Joel Greenblatt in his book on special-situation investment "You Can Be a Stock Market Genius" (ISBN 0-684-84007-3, pp 247)

Joel Greenblatt achieved annual returns at the hedge fund Gotham Capital of over 50% per year for 10 years from 1985 to 1995 before closing the fund and returning his investors' money. He is known for investing in special situations such as spin-offs, mergers, and divestitures.

Investment specific technological progress

Introduction

To model how something is produced, think of a box that in one end takes in inputs such as labor (employees) and capital (equipment, buildings, etc.) and in another end spits out the final good (see Figure 1). With this picture in mind now one can ask, how does technological progress affect production? One way of thinking is that technological progress affects specific inputs (arrows going in) such as equipment and buildings. To realize the benefits of such technological change for production these inputs must be purchased. So for example, the advent of the microchip (an important technological improvement in computers) will affect the production of Ford cars only if Ford Motor Co.'s assembly plants (the red box) invest in computers with microchips (instead of computers with punch cards) and use them (they are one of the arrows going in the box) in the production of Mustangs (the arrow coming out). As the name suggests, this is investment-specific technological progress---it requires investing in new machines or buildings which contain or embody the latest technology. Notice that the term investment can be very general: not only must a firm buy the new technology to reap its benefits, but it also must invest in training its workers and managers to be able to use this new technology (Greenwood & Jovanovic 2001) .

Importance

Identifying investment-specific technological progress is important, because knowing what type of technological progress is operating in an economy will determine how someone (should) want his or her tax dollars to be spent and how he or she may want to invest his or her savings (Gort et al 1999). If "investment-specific" technological change is the main source of progress, then one would want his or her dollars spent on helping firms buy new equipment and renovate their plants, because these investments will improve production and hence what you consume. Furthermore, one may want to help pay for current employee training in using new technologies (to keep them up to date) or subsidize the education of new employees (who will enter the job market knowing how to use the new technology). So, the type of technological progress will also matter for unemployment and education issues. Finally, if technological progress is "investment-specific" you may want to direct your money towards the research and development (R & D) of new technologies (like quantum computers or alternative energy sources) (Krusell 1998).

More generally, why is any type of technological progress important? Technological change has made our lives easier. Because of technological progress, people can work less, make more money and enjoy more leisure time (Greenwood & Vandenbroucke 2006). Women have been able to break away from the traditional "housewife" role, join the labor-force in greater numbers (Greenwood et al 2005) and become less economically dependent on men (Greenwood & Guner 2004). Finally, technological progress has been shown to affect the fall in child labor starting around 1900 (Greenwood & Seshadri 2005). Figure 2 illustrates this last point: as of 1900 child labor's share of the paid labor force began to fall.

Figure 2

A Simple Example: the microwave oven

An example of investment-specific technological progress is the microwave oven. The idea of the microwave came to be by accident: in 1946 an engineer noticed that a candy bar in his pocket had melted while working on something completely unrelated to cooking (Gallawa 2005). The development of this good, from melting the candy bar to the home appliance we know today, took time and the investment of resources to make a microwave small and cheap. The first microwave oven cost between 2000 and 3000 dollars and was housed in refrigerator-sized cabinets (Gallawa 2005)! Today, almost any college student can enjoy a 3-minute microwaveable meal in the smallest dorm room. But a microwave's uses do not stop at the dorm room. Many industries have found microwave heating advantageous: it has been used to dry cork, ceramics, paper, leather, and so on (Gallawa 2005). However, for either college students or firms to reap the benefits of quick warming, they must first "invest" in a microwave oven (that "embodies" the technological advance). To realize the benefits of investment-specific technological progress you must first invest in a technology that embodies it.

How do you measure investment-specific technological progress?

While measuring technological progress is not easy, economists have found indirect ways of estimating it. If "'investment-specific'" technological progress makes producing goods easier, then we should expect the price of these goods (relative to the price of other goods) to decrease. In particular, "investment-specific" technological change has affected the prices of two inputs into the production process: equipment and structures. We think of equipment as machines (like computers) and structures as buildings. If there is technological progress in the production (or creation) of these goods, then we should expect the price of them to fall or the value of them to rise relative to older versions of the same good.

Figure 3 (the pink line) shows how the price of new producer durables (such as equipment) in the US relative to the price of new consumer nondurables (like clothing) has consistently declined over the past fifty years (Gort et al 1999). By relative price of producer durables we mean dividing the price that firms pay (for inputs of production) by the price that a regular consumer pays (for things like jeans). We use relative prices so we can say how many units of equipment can be bought instead (or in terms) of buying one unit of consumer goods. Figure 3 (the pink line) says that over time, firms have been able to buy more and more units of equipment instead of one unit of consumption, especially when we take into account that the quality of equipment being acquired has increased (a computer today is much faster than a computer five years ago and we should take that into account when comparing their prices). If we do not take into account quality (which is wrong) it looks like the price of equipment has not decreased as much (see the black line in Figure 3).

Figure 3

Measuring the price of structures is more complicated than measuring the price of equipment, but economists have again been able to get an idea of how much progress there has been in structures (such as buildings). One approach is that if newer buildings were constructed or designed using newer technologies then they should be worth more than older buildings (because they embody the new technology (Gort et al 1999). In particular, they should rent for more. As Figure 4 shows, this is true. Renting a square foot in a new building is much more expensive than renting a square foot in a building forty years old. So it must be the case that you are paying for a nicer, more functional and maybe even safer building.

Figure 4

Based on Figures 3 and 4 we can conclude that investment-specific technological change is operating in the US. Estimates suggest that the rate of technological progress in equipment and structures is about 3.2% and 1%, respectively (Gort et al 1999) (Greenwood et al 1997).

Conclusion

In the second section it was mentioned that "investment-specific" technological change is important since it will affect production (both in quality and size). An important question then is, just how much "bang for your buck" do you get with "investment-specific" technological change? The answer is quite astounding; economists have found that 37% of growth in US output (production) is due to technological progress in equipment and 15% is due to technological progress in structures (Gort et al 1999) (Greenwood et al 1997). All in all, more than half (37% + 15% = 52%) of the growth of the US economy is due to "investment-specific" technological change (Gort et al 1999) (Greenwood et al 1997).

Investment

Types of investments

The term "investment" is used differently in economics and in finance. Economists refer to a real investment (such as a machine or a house), while financial economists refer to a financial asset, such as money that is put into a bank or the market, which may then be used to buy a real asset.

Business Management

The investment decision (also known as capital budgeting) is one of the fundamental decisions of business management: managers determine the assets that the business enterprise obtains. These assets may be physical (such as buildings or machinery), intangible (such as patents, software, goodwill), or financial (see below). The manager must assess whether the net present value of the investment to the enterprise is positive; the net present value is calculated using the enterprise's marginal cost of capital.

A business might invest with the goal of making profit. These are marketable securities or passive investment. It might also invest with the goal of controlling or influencing the operation of the second company, the investee. These are called intercorporate, long-term and strategic investments. Hence, a company can have none, some or total control over the investee's strategic, operating, investing and financing decisions. One can control a company by owning over 50% ownership, or have the ability to elect a majority of the Board of Directors.

Economics

In economics, investment is the production per unit time of goods which are not consumed but are to be used for future production. Examples include tangibles (such as building a railroad or factory) and intangibles (such as a year of schooling or on-the-job training). In measures of national income and output, gross investment I is also a component of Gross domestic product (GDP), given in the formula GDP = C + I + G + NX, where C is consumption, G is government spending, and NX is net exports. Thus investment is everything that remains of production after consumption, government spending, and exports are subtracted.

I is divided into non-residential investment (such as factories) and residential investment (new houses). Net investment deducts depreciation from gross investment. It is the value of the net increase in the capital stock per year.

Investment, as production over a period of time ("per year"), is not capital. The time dimension of investment makes it a flow. By contrast, capital is a stock, that is, an accumulation measurable at a point in time (say December 31st).

Investment is often modeled as a function of Income and Interest rates, given by the relation I = f(Y, r). An increase in income encourages higher investment, whereas a higher interest rate may discourage investment as it becomes more costly to borrow money. Even if a firm chooses to use its own funds in an investment, the interest rate represents an opportunity cost of investing those funds rather than loaning them out for interest.

Finance

In finance, investment=cost of capital, like buying securities or other monetary or paper (financial) assets in the money markets or capital markets, or in fairly liquid real assets, such as gold, real estate, or collectibles. Valuation is the method for assessing whether a potential investment is worth its price. Returns on investments will follow the risk-return spectrum.

Types of financial investments include shares, other equity investment, and bonds (including bonds denominated in foreign currencies). These financial assets are then expected to provide income or positive future cash flows, and may increase or decrease in value giving the investor capital gains or losses.

Trades in contingent claims or derivative securities do not necessarily have future positive expected cash flows, and so are not considered assets, or strictly speaking, securities or investments. Nevertheless, since their cash flows are closely related to (or derived from) those of specific securities, they are often studied as or treated as investments.

Investments are often made indirectly through intermediaries, such as banks, mutual funds, pension funds, insurance companies, collective investment schemes, and investment clubs. Though their legal and procedural details differ, an intermediary generally makes an investment using money from many individuals, each of whom receives a claim on the intermediary.

Personal finance

Within personal finance, money used to purchase shares, put in a collective investment scheme or used to buy any asset where there is an element of capital risk is deemed an investment. Saving within personal finance refers to money put aside, normally on a regular basis. This distinction is important, as investment risk can cause a capital loss when an investment is realized, unlike saving(s) where the more limited risk is cash devaluing due to inflation.

In many instances the terms saving and investment are used interchangeably, which confuses this distinction. For example many deposit accounts are labeled as investment accounts by banks for marketing purposes. Whether an asset is a saving(s) or an investment depends on where the money is invested: if it is cash then it is savings, if its value can fluctuate then it is investment.

Real estate

In real estate, investment is money used to purchase property for the sole purpose of holding or leasing for income and where there is an element of capital risk. Unlike other economic or financial investment, real estate is purchased. The seller is also called a Vendor and normally the purchaser is called a Buyer.

Residential real estate

The most common form of real estate investment as it includes the property purchased as other people's houses. In many cases the Buyer does not have the full purchase price for a property and must engage a lender such as a Bank, Finance company or Private Lender. Herein the lender is the investor as only the lender stands to gain returns from it. Different countries have their individual normal lending levels, but usually they will fall into the range of 70-90% of the purchase price. Against other types of real estate, residential real estate is the least risky.

Commercial real estate

Commercial real estate is the owning of a small building or large warehouse a company rents from so that it can conduct its business. Due to the higher risk of Commercial real estate, lending rates of banks and other lenders are lower and often fall in the range of 50-70%.

Corporate finance

Corporate finance is an area of finance dealing with the financial decisions corporations make and the tools and analysis used to make these decisions. The primary goal of corporate finance is to maximize corporate value while reducing the firm's financial risks. Although it is in principle different from managerial finance which studies the financial decisions of all firms, rather than corporations alone, the main concepts in the study of corporate finance are applicable to the financial problems of all kinds of firms.

The discipline can be divided into long-term and short-term decisions and techniques. Capital investment decisions are long-term choices about which projects receive investment, whether to finance that investment with equity or debt, and when or whether to pay dividends to shareholders. On the other hand, the short term decisions can be grouped under the heading "Working capital management". This subject deals with the short-term balance of current assets and current liabilities; the focus here is on managing cash, inventories, and short-term borrowing and lending (such as the terms on credit extended to customers).

The terms Corporate finance and Corporate financier are also associated with investment banking. The typical role of an investment banker is to evaluate investment projects for a bank to make investment decisions.

Capital investment decisions

Capital investment decisions^[1] are long-term corporate finance decisions relating to fixed assets and capital structure. Decisions are based on several inter-related criteria. Corporate management seeks to maximize the value of the firm by investing in projects which yield a positive net present value when valued using an appropriate discount rate. These projects must also be financed appropriately. If no such opportunities exist, maximizing shareholder value dictates that management return excess cash to shareholders. Capital investment decisions thus comprise an investment decision, a financing decision, and a dividend decision.

The investment decision

Main article: Capital budgeting

Management must allocate limited resources between competing opportunities ("projects") in a process known as capital budgeting. Making this capital allocation decision requires estimating the value of each opportunity or project: a function of the size, timing and predictability of future cash flows.

Project valuation

Further information: stock valuation and fundamental analysis

In general, each project's value will be estimated using a discounted cash flow (DCF) valuation, and the opportunity with the highest value, as measured by the resultant net present value (NPV) will be selected (see Fisher separation theorem; John Burr Williams: Theory). This requires estimating the size and timing of all of the incremental cash flows resulting from the project. These future cash flows are then discounted to determine their present value (see Time value of money). These present values are then summed, and this sum net of the initial investment outlay is the NPV.

The NPV is greatly influenced by the discount rate. Thus selecting the proper discount rate—the project "hurdle rate"—is critical to making the right decision. The hurdle rate is the minimum acceptable return on an investment—i.e. the project appropriate discount rate. The hurdle rate should reflect the riskiness of the investment, typically measured by volatility of cash flows, and must take into account the financing mix. Managers use models such as the CAPM or the APT to estimate a discount rate appropriate for a particular project, and use the weighted average cost of capital (WACC) to reflect the financing mix selected. (A common error in choosing a discount rate for a project is to apply a WACC that applies to the entire firm. Such an approach may not be appropriate where the risk of a particular project differs markedly from that of the firm's existing portfolio of assets.)

In conjunction with NPV, there are several other measures used as (secondary) selection criteria in corporate finance. These are visible from the DCF and include payback period, IRR, Modified IRR, equivalent annuity, capital efficiency, and ROI; see list of valuation topics.

Valuing flexibility

Main articles: Real options analysis and decision tree

In many cases, for example R&D projects, a project may open (or close) paths of action to the company, but this reality will not typically be captured in a strict NPV approach. Management will therefore (sometimes) employ tools which place an explicit value on these options. So, whereas in a DCF valuation the most likely or average or scenario specific cash flows are discounted, here the “flexibile and staged nature” of the investment is modelled, and hence "all" potential payoffs are considered. The difference between the two valuations is the "option value" inherent in the project.

The two most common tools are Decision Tree Analysis (DTA) and Real options analysis:

• The DTA approach attempts to capture flexibility by incorporating likely events and consequent management decisions into the valuation. In the decision tree, each management decision in response to an "event" generates a "branch" or "path" which the company could follow. (For example, management will only proceed with stage 2 of the project given that stage 1 was successful; stage 3, in turn, depends on stage 2. In a DCF model, on the other hand, there is no "branching" - each scenario must be modelled separately.) The highest value path (probability weighted) is regarded as representative of project value

• The real options approach is used when the value of a project is contingent on the value of some other asset or underlying variable. (For example, the viability of a mining project is contingent on the price of gold; if the price is too low, management will abandon the mining rights, if sufficiently high, management will develop the ore body. Again, a DCF valuation would capture only one of these outcomes.) Here, using financial option theory as a framework, the decision to be taken is identified as corresponding to either a call option or a put option - valuation is then via the Binomial model or, less often for this purpose, via Black Scholes; see Contingent claim valuation. The "true" value of the project is then the NPV of the "most likely" scenario plus the option value.

Quantifying uncertainty

Further information: Monte Carlo methods in finance

Given the uncertainty inherent in project forecasting and valuation, analysts will wish to assess the sensitivity of project NPV to the various inputs to the DCF model. In a typical sensitivity analysis the analyst will vary one key factor, while ceteris paribus holding constant all other inputs. The sensitivity of NPV to a change in that factor is then observed (calculated as Δ NPV / Δ factor). For example, the analyst will set annual revenue growth rates at 5% for "Worst Case", 10% for "Likely Case" and 25% for "Best Case" - and produce three corresponding NPVs.

Using a related technique, analysts may also run scenario based forecasts so as to observe the value of the project under various outcomes. Under this technique, a scenario comprises a particular outcome for economy-wide, "global" factors (exchange rates, commodity prices) as well as for company-specific factors (revenue growth rates, unit costs). Here, extending the example above, key inputs in addition to growth are also adjusted, and NPV is calculated for the various scenarios. Analysts then plot these results to produce a "value-surface" (or even a "value-space"), where NPV is a function of several variables. Another application of this methodology is to determine an "unbiased NPV", where management determines a (subjective) probability for each scenario and the NPV for the project is then the probability-weighted average of the various scenarios. Note that for scenario based analysis, the various combinations of inputs must be internally consistent, whereas for the sensitivity approach these need not be so.

A further advancement is to construct stochastic or probabilistic financial models - as opposed to the traditional static and deterministic models as above. For this purpose, the most common method is to use Monte Carlo simulation to analyze the project’s NPV (introduced to finance by David B. Hertz in 1964). Here, the cash flow components that are (heavily) impacted by uncertainty are simulated, mathematically reflecting their "random characteristics". The simulation produces several thousand trials (in contrast to the scenario approach above) and outputs a histogram of project NPV. The average NPV of the potential investment - as well as its volatility and other sensitivities - is then observed. (Typically, an add-in such as Crystal Ball is used to run simulations in spreadsheet based DCF models.)

Here, continuing the above example, instead of assigning three discrete values to revenue growth, the analyst would assign an appropriate probability distribution (commonly triangular or beta). This distribution - and that of the other sources of uncertainty - would then be "sampled" repeatedly so as to generate the several thousand realistic (but random) scenarios, and the output is a realistic, representative set of valuations. The resultant statistics (average NPV and standard deviation of NPV) will be a more accurate mirror of the project's "randomness" than the variance observed under the traditional scenario based approach.

The financing decision

Main article: Capital structure

Achieving the goals of corporate finance requires that any corporate investment be financed appropriately. As above, since both hurdle rate and cash flows (and hence the riskiness of the firm) will be affected, the financing mix can impact the valuation. Management must therefore identify the "optimal mix" of financing—the capital structure that results in maximum value. (See Balance sheet, WACC, Fisher separation theorem; but, see also the Modigliani-Miller theorem.)

The sources of financing will, generically, comprise some combination of debt and equity. Financing a project through debt results in a liability that must be serviced—and hence there are cash flow implications regardless of the project's success. Equity financing is less risky in the sense of cash flow commitments, but results in a dilution of ownership and earnings. The cost of equity is also typically higher than the cost of debt (see CAPM and WACC), and so equity financing may result in an increased hurdle rate which may offset any reduction in cash flow risk.

Management must also attempt to match the financing mix to the asset being financed as closely as possible, in terms of both timing and cash flows.

One of the main theories of how firms make their financing decisions is the Pecking Order Theory, which suggests that firms avoid external financing while they have internal financing available and avoid new equity financing while they can engage in new debt financing at reasonably low interest rates. Another major theory is the Trade-Off Theory in which firms are assumed to trade-off the Tax Benefits of debt with the Bankruptcy Costs of debt when making their decisions. An emerging area in finance theory is Right-financing whereby investment banks and corporations can enhance investment return and company value over time by determining the right investment objectives, policy framework, institutional structure, source of financing (debt or equity) and expenditure framework within a given economy and under given market conditions. One last theory about this decision is the Market timing hypothesis which states that firms look for the cheaper type of financing regardless of their current levels of internal resources, debt and equity.

The dividend decision

Main article: The Dividend Decision

 The dividend is calculated mainly on the basis of the company's unappropriated profit and its business prospects for the coming year.  If there are no NPV positive opportunities, i.e. where returns exceed the hurdle rate, then management must return excess cash to investors. These free cash flows comprise cash remaining after all business expenses have been met.

This is the general case, however there are exceptions. For example, investors in a "Growth stock", expect that the company will, almost by definition, retain earnings so as to fund growth internally. In other cases, even though an opportunity is currently NPV negative, management may consider “investment flexibility” / potential payoffs and decide to retain cash flows; see above and Real options.

Management must also decide on the form of the distribution, generally as cash dividends or via a share buyback. There are various considerations: where shareholders pay tax on dividends, companies may elect to retain earnings, or to perform a stock buyback, in both cases increasing the value of shares outstanding; some companies will pay "dividends" from stock rather than in cash. (See Corporate action.) Today it is generally accepted that dividend policy is value neutral (see Modigliani-Miller theorem).

Working capital management

Main article: Working capital

Decisions relating to working capital and short term financing are referred to as working capital management. These involve managing the relationship between a firm's short-term assets and its short-term liabilities. The goal of Working capital management is to ensure that the firm is able to continue its operations and that it has sufficient cash flow to satisfy both maturing short-term debt and upcoming operational expenses.

Decision criteria

Working capital is the amount of capital which is readily available to an organization. That is, working capital is the difference between resources in cash or readily convertible into cash (Current Assets) and cash requirements (Current Liabilities). So the decisions relating to working capital are always current decisions, i.e., short term decisions.

The short term decisions of the firm are similar to those of long term in terms of risk and return, but they differ in many other ways like time factor, discounting consideration, liquidity etc. So these decisions are not taken on the same basis as long term decisions. These decisions have different criteria like cash flow and profitability.

• The most important critreon for making shor term decisons is cash flows. And the best measure of cash flow is net operating cycle or cash conversion cycle. It represents the time difference between cash payment for raw materials and cash collection for sales. Another aspect of cash conversion cycle is gross operating cycle which is same as net operating cycle except the fact that it does not take into account the creditors deferral period. Cash conversion cycle indicates the firm's ability to convert its resources into cash. Because this number effectively corresponds to the time that the firm's cash is tied up in operations and unavailable for other activities, management generally aims at a low net count.

• In this context, the most useful measure of profitability is Return on capital (ROC). The result is shown as a percentage, determined by dividing relevant income for the 12 months by capital employed; Return on equity (ROE) shows this result for the firm's shareholders. Firm value is enhanced when, and if, the return on capital, which results from working capital management, exceeds the cost of capital, which results from capital investment decisions as above. ROC measures are therefore useful as a management tool, in that they link short-term policy with long-term decision making. See Economic value added (EVA).

Management of working capital

Guided by the above criteria, management will use a combination of policies and techniques for the management of working capital. These policies aim at managing the current assets (generally cash and cash equivalents, inventories and debtors) and the short term financing, such that cash flows and returns are acceptable.

• Cash management. Identify the cash balance which allows for the business to meet day to day expenses, but reduces cash holding costs.
• Inventory management. Identify the level of inventory which allows for uninterrupted production but reduces the investment in raw materials - and minimizes reordering costs - and hence increases cash flow; see Supply chain management; Just In Time (JIT); Economic order quantity (EOQ); Economic production quantity (EPQ).
• Debtors management. Identify the appropriate credit policy, i.e. credit terms which will attract customers, such that any impact on cash flows and the cash conversion cycle will be offset by increased revenue and hence Return on Capital (or vice versa); see Discounts and allowances.
• Short term financing. Identify the appropriate source of financing, given the cash conversion cycle: the inventory is ideally financed by credit granted by the supplier; however, it may be necessary to utilize a bank loan (or overdraft), or to "convert debtors to cash" through "factoring".

Financial risk management

Main article: Financial risk management

Risk management is the process of measuring risk and then developing and implementing strategies to manage that risk. Financial risk management focuses on risks that can be managed ("hedged") using traded financial instruments (typically changes in commodity prices, interest rates, foreign exchange rates and stock prices). Financial risk management will also play an important role in cash management.

This area is related to corporate finance in two ways. Firstly, firm exposure to business risk is a direct result of previous Investment and Financing decisions. Secondly, both disciplines share the goal of creating, or enhancing, firm value. All large corporations have risk management teams, and small firms practice informal, if not formal, risk management.

Derivatives are the instruments most commonly used in Financial risk management. Because unique derivative contracts tend to be costly to create and monitor, the most cost-effective financial risk management methods usually involve derivatives that trade on well-established financial markets. These standard derivative instruments include options, futures contracts, forward contracts, and swaps.

Relationship with other areas in finance

Investment banking

Use of the term “corporate finance” varies considerably across the world. In the United States it is used, as above, to describe activities, decisions and techniques that deal with many aspects of a company’s finances and capital. In the United Kingdom and Commonwealth countries, the terms “corporate finance” and “corporate financier” tend to be associated with investment banking - i.e. with transactions in which capital is raised for the corporation.

Personal and public finance

Corporate finance utilizes tools from almost all areas of finance. Some of the tools developed by and for corporations have broad application to entities other than corporations, for example, to partnerships, sole proprietorships, not-for-profit organizations, governments, mutual funds, and personal wealth management. But in other cases their application is very limited outside of the corporate finance arena. Because corporations deal in quantities of money much greater than individuals, the analysis has developed into a discipline of its own. It can be differentiated from personal finance and public finance.

Corporate finance

Corporate finance is an area of finance dealing with the financial decisions corporations make and the tools and analysis used to make these decisions. The primary goal of corporate finance is to maximize corporate value while reducing the firm's financial risks. Although it is in principle different from managerial finance which studies the financial decisions of all firms, rather than corporations alone, the main concepts in the study of corporate finance are applicable to the financial problems of all kinds of firms.

The discipline can be divided into long-term and short-term decisions and techniques. Capital investment decisions are long-term choices about which projects receive investment, whether to finance that investment with equity or debt, and when or whether to pay dividends to shareholders. On the other hand, the short term decisions can be grouped under the heading "Working capital management". This subject deals with the short-term balance of current assets and current liabilities; the focus here is on managing cash, inventories, and short-term borrowing and lending (such as the terms on credit extended to customers).

The terms Corporate finance and Corporate financier are also associated with investment banking. The typical role of an investment banker is to evaluate investment projects for a bank to make investment decisions.

Capital investment decisions

Capital investment decisions^[1] are long-term corporate finance decisions relating to fixed assets and capital structure. Decisions are based on several inter-related criteria. Corporate management seeks to maximize the value of the firm by investing in projects which yield a positive net present value when valued using an appropriate discount rate. These projects must also be financed appropriately. If no such opportunities exist, maximizing shareholder value dictates that management return excess cash to shareholders. Capital investment decisions thus comprise an investment decision, a financing decision, and a dividend decision.

The investment decision

Main article: Capital budgeting

Management must allocate limited resources between competing opportunities ("projects") in a process known as capital budgeting. Making this capital allocation decision requires estimating the value of each opportunity or project: a function of the size, timing and predictability of future cash flows.

[edit] Project valuation

Further information: stock valuation and fundamental analysis

In general, each project's value will be estimated using a discounted cash flow (DCF) valuation, and the opportunity with the highest value, as measured by the resultant net present value (NPV) will be selected (see Fisher separation theorem; John Burr Williams: Theory). This requires estimating the size and timing of all of the incremental cash flows resulting from the project. These future cash flows are then discounted to determine their present value (see Time value of money). These present values are then summed, and this sum net of the initial investment outlay is the NPV.

The NPV is greatly influenced by the discount rate. Thus selecting the proper discount rate—the project "hurdle rate"—is critical to making the right decision. The hurdle rate is the minimum acceptable return on an investment—i.e. the project appropriate discount rate. The hurdle rate should reflect the riskiness of the investment, typically measured by volatility of cash flows, and must take into account the financing mix. Managers use models such as the CAPM or the APT to estimate a discount rate appropriate for a particular project, and use the weighted average cost of capital (WACC) to reflect the financing mix selected. (A common error in choosing a discount rate for a project is to apply a WACC that applies to the entire firm. Such an approach may not be appropriate where the risk of a particular project differs markedly from that of the firm's existing portfolio of assets.)

In conjunction with NPV, there are several other measures used as (secondary) selection criteria in corporate finance. These are visible from the DCF and include payback period, IRR, Modified IRR, equivalent annuity, capital efficiency, and ROI; see list of valuation topics.

Public finance

Public finance is a field of economics concerned with paying for collective or governmental activities, and with the administration and design of those activities. The field is often divided into questions of what the government or collective organizations should do or are doing, and questions of how to pay for those activities. The broader term (public economics) and the narrower term (government finance) are also often used.

Overview

The proper role of government provides a starting point for the analysis of public finance. Private markets, if certain conditions are met, will allocate goods and services among individuals efficiently (in the sense that no waste occurs and that individual tastes are matching with the economy's productive abilities). If private markets were able to provide efficient outcomes and if the distribution of income was socially acceptable, then there would be little or no scope for government. In many cases, however, conditions for private market efficiency are violated. For example, if many people can enjoy the same good at the same time (non-rival, non-excludable consumption), then private markets may supply too little of that good. National defense is one example of non-rival consumption, or of a public good.

"Market failure" occurs when private markets do not allocate goods or services efficiently. The existence of market failure provides an efficiency-based rationale for collective or governmental provision of goods and services. Externalities, public goods, informational advantages, strong economies of scale, and network effects can cause market failures. Public provision via a government or a voluntary association, however, is subject to other inefficiencies, termed "government failure."

Under broad assumptions, government decisions about the efficient scope and level of activities can be efficiently separated from decisions about the design of taxation systems (Diamond-Mirlees separation). In this view, public sector programs should be designed to maximize social benefits minus costs (cost-benefit analysis), and then revenues needed to pay for those expenditures should be raised through a taxation system that creates the fewest efficiency losses caused by distortion of economic activity as possible. In practice, government budgeting is substantially more complicated and often results in inefficient practices.

Government can pay for spending by borrowing (borrowing), although borrowing is a method of distributing tax burdens through time rather than a replacement for taxes. A deficit is the difference between government spending and revenues. The accumulation of deficits over time is the total public debt. Deficit finance allows governments to smooth tax burdens over time, and gives governments an important fiscal policy tool. Deficits can also narrow the options of successor governments.

Public finance is closely connected to issues of income distribution and social equity. Governments can reallocate income through transfer payments or by designing tax systems that treat high-income and low-income households differently.

The "Public Choice" approach to public finance seeks to explain how self-interested voters, politicians, and bureaucrats actually operate, rather than how they should operate.

Government expenditures

Main article: Government spending

Economists classify government expenditures into three main types. Government purchases of goods and services for current use are classed as government consumption. Government purchases of goods and services intended to create future benefits--- such as infrastructure investment or research spending--- are classed as government investment. Government expenditures that are not purchases of goods and services, and instead just represent transfers of money--- such as social security payments--- are called transfer payments.^[1]

Government operations

Main article: Government operations

Government operations are those activities involved in the running of a state or a functional equivalent of a state (for example, tribes, secessionist movements or revolutionary movements) for the purpose of producing value for the citizens. Government operations have the power to make, and the authority to enforce rules and laws within a civil, corporate, religious, academic, or other organization or group.^[2] In its broadest sense, "to govern" means to rule over or supervise, whether over a state, a set group of people, or a collection of people.^[3]

Income distribution

Main article: Income distribution

• Income distribution - Some forms of government expenditure are specifically intended to transfer income from some groups to others. For example, governments sometimes transfer income to people that have suffered a loss due to natural disaster. Likewise, public pension programs transfer wealth from the young to the old. Other forms of government expenditure which represent purchases of goods and services also have the effect of changing the income distribution. For example, engaging in a war may transfer wealth to certain sectors of society. Public education transfers wealth to families with children in these schools. Public road construction transfers wealth from people that do not use the roads to those people that do (and to those that build the roads).

• Employment insurance
• Health Care

Financing government expenditures

Budgeted revenues of governments in 2006

Government financing can be achieved by taxes, government borrowing, or seigniorage. How a government chooses to finance its activities can have important effects on the distribution of income and wealth (income redistribution) and on the efficiency of markets (effect of taxes on market prices and efficiency). The issue of how taxes affect income distribution is closely related to tax incidence, which examines the distribution of tax burdens after market adjustments are taken into account. Public finance research also analyzes effects of the various types of taxes and types of borrowing as well as administrative concerns, such as tax enforcement.

Taxes

Main article: Tax

A tax is a financial charge or other levy imposed on an individual or a legal entity by a state or a functional equivalent of a state (for example, tribes, secessionist movements or revolutionary movements). Taxes could also be imposed by a subnational entity. Taxes consist of direct tax or indirect tax, and may be paid in money or as corvée labor. A tax may be defined as a "pecuniary burden laid upon individuals or property to support the government [ . . .] a payment exacted by legislative authority."^[4] A tax "is not a voluntary payment or donation, but an enforced contribution, exacted pursuant to legislative authority" and is "any contribution imposed by government [ . . .] whether under the name of toll, tribute, tallage, gabel, impost, duty, custom, excise, subsidy, aid, supply, or other name."^[5]

Debt

Main article: Government debt

Governments, like any other legal entity, can take out loans, issue bonds and make financial investments. Based on the taxing authority of the entity, they issue bonds such as tax increment bonds or revenue bonds. Government debt (also known as public debt or national debt) is money (or credit) owed by any level of government; either central government, federal government, municipal government or local government.

As the government represents the people, government debt can be seen as an indirect debt of the taxpayers. Government debt can be categorized as internal debt, owed to lenders within the country, and external debt, owed to foreign lenders. Governments usually borrow by issuing securities such as government bonds and bills. Less credit worthy countries sometimes borrow directly from commercial banks or international institutions such as the International Monetary Fund or the World Bank.

Most government budgets are calculated on a cash basis, meaning that revenues are recognized when collected and outlays are recognized when paid. Some consider all government liabilities, including future pension payments and payments for goods and services the government has contracted for but not yet paid, as government debt. This approach is called accrual accounting, meaning that obligations are recognized when they are acquired, or accrued, rather than when they are paid.

Seigniorage

Main article: Seigniorage

Seigniorage is the net revenue derived from the issuing of currency. It arises from the difference between the face value of a coin or bank note and the cost of producing, distributing and eventually retiring it from circulation. Seigniorage is an important source of revenue for some national banks.

The role of public spending and taxes

Externalities and government policy

• Internalization of externalities
• The Coase Theorem. The Coase theorem states that when trade in an externality is possible and there are no transaction costs, bargaining will lead to an efficient outcome regardless of the initial allocation of property rights.

Public goods

• Characteristics

characteristics of public goods are non - excludability and transferable. Non excludabilty means the consumption of the goods is not limited on specific group of consumers, that is the satisfaction of the people watching fireworks display is not limited to the owners of the fireworks. The transferability feature of the public goods means that the consumption of an individual will not lead to deprive the other, that is, if a consumer is doing fishing on a pond, another person may do fishing as well on the same pond.

• Efficient output of a pure public good

Personal finance

Personal finance is the application of the principles of finance to the monetary decisions of an individual or family unit. It addresses the ways in which individuals or families obtain, budget, save and spend monetary resources over time, taking into account various financial risks and future life events. Components of personal finance might include checking and savings accounts, credit cards and consumer loans, investments in the stock market, retirement plans, social security benefits, insurance policies, and income tax management.

Personal financial planning

A key component of personal finance is financial planning, a dynamic process that requires regular monitoring and reevaluation. In general, it has five steps:

1. Assessment: One's personal financial situation can be assessed by compiling simplified versions of financial balance sheets and income statements. A personal balance sheet lists the values of personal assets (e.g., car, house, clothes, stocks, bank account), along with personal liabilities (e.g., credit card debt, bank loan, mortgage). A personal income statement lists personal income and expenses.
2. Setting goals: Two examples are "retire at age 65 with a personal net worth of $200,000 American" and "buy a house in 3 years paying a monthly mortgage servicing cost that is no more than 25% of my gross income". It is not uncommon to have several goals, some short term and some long term. Setting financial goals helps direct financial planning.
3. Creating a plan: The financial plan details how to accomplish your goals. It could include, for example, reducing unnecessary expenses, increasing one's employment income, or investing in the stock market.
4. Execution: Execution of one's personal financial plan often requires discipline and perseverance. Many people obtain assistance from professionals such as accountants, financial planners, investment advisers, and lawyers.
5. Monitoring and reassessment: As time passes, one's personal financial plan must be monitored for possible adjustments or reassessments.

Typical goals most adults have are paying off credit card and or student loan debt, retirement, college costs for children, medical expenses, and estate planning.
