11.4 Specific Valuation Techniques
A variety of techniques are available for conducting a business valuation. Part of the skill and expertise of a valuation analyst is the ability to select the appropriate technique for the situation at hand. Even when one technique is chosen, valuation under other techniques is often determined for comparative and confirmative purposes. Some analysts present a weighted average of the outcome of several techniques as their final conclusion, while others select a final value from the range of outcomes without resorting to formal weighting.
Factors to be Considered in a Business Valuation
Whatever the technique, the analyst should consider a variety of factors about the business and its industry. Among the factors to be considered are the following:This listing is drawn from American Institute of Certified Public Accountants (2003).
- What is the stage of the company’s development? Is it new, established and growing, mature, or declining?
- What is the current and prospective state of the industry in which the company operates, and of the economy in which it competes? How attractive is the industry to capital suppliers?
- What is the experience and competence of the members of top management and the company’s Board of Directors?
- What is the company’s position in the marketplace—for example, its market share—and what major competitors does it have?
- Are there barriers to entry in the company’s marketplace?
- What are the competitive forces in the company’s industry (recall Porter’s five competitive forces, discussed in an earlier chapter)?
- Does the company have proprietary technology, products, or services, and what is the nature of the protection, such as patent rights or exclusive licensing?
- What is the nature and quality of the company’s work force, including employer–employee relations, pay and benefits, labor supply, and the like?
- What is the nature and quality of the company’s suppliers and of the company’s customers? Is the company dependent on a small number of customers or vendors, or does it have a broad base? Are the customers and suppliers financially solid?
- Are there strategic relationships with suppliers, customers, and sources of financing? The existence of such relationships may be a positive or a negative factor when valuing the company.
- What is the company’s cost structure (operating leverage, fixed-variable mix) and its financial strength indicated by debt capacity, free cash flow, and the like?
- What risk factors does the company face?
The consideration of risk factors is an especially important part of business valuation. Uncertainties or concerns in any of the above areas may signify risks to be considered.
Two simple approaches to business valuation are (a) determining the value of the company’s net assets (assets minus liabilities) and (b) identifying the fair market value of a similar business. We discuss them briefly in the following sections, although they often prove unsatisfactory.
One approach to business valuation involves direct estimation of the value of the net assets to be acquired (=assets to be acquired by the buyer minus any liabilities to be assumed by the buyer). An asset-based approachAn approach to business valuation that involves direct estimation of the value of the net assets to be acquired. typically begins by examining the firm’s balance sheet. However, there are several reasons why book (recorded) values are typically unsatisfactory indicators of business value:
- Book values reflect the accumulated effects of applying Generally Accepted Accounting Principles to the past transactions of the firm and have no necessary connection to current economic value.
- Book values may not reflect the impact of changing prices (inflation) or technological change.
- Balance sheets may not include all the relevant assets of the business, especially unrecorded intangible assets.
Given these deficiencies, the analyst attempts to adjust book values to arrive at an overall business valuation. The analyst examines and values each asset and liability to estimate its fair market value, using techniques such as the determination of market values for comparable assets, expert appraisals, and price index-based inflation adjustments. It is important to identify and value unrecorded intangible assets, including goodwill, and unrecorded liabilities, such as environmental liabilities, operating leases, and other off-balance-sheet and contingent obligations.
Direct Comparison Approach
The logic of a direct comparison approachCompares the average of other businesses to quickly value one. Based on the idea that similar assets should sell for similar prices. lies in the idea that similar assets should sell for similar prices, a principle well established in other markets.See Cornell (1993). In real estate, for example, the market value of a house could be estimated by finding recent selling prices for substantially similar houses in comparable neighborhoods. Finding sales of comparable businesses, however, is difficult. Transactions are few, and comprehensive data sources do not exist. Thus, a true direct comparison approach cannot generally be used in business valuation.
However, a form of direct comparison exists when some measure or ratio serves as the link between the business valuation in question and other businesses. For example, professional practices like Certified Public Accountant (CPA) firms often sell for a multiple of billings, perhaps two to three times annual billings. For example, the average price–earnings (P/E) ratio of similar public firms in the industry might be used. If such firms sell for 12 times earnings, we can apply that same measure to a business being valued. The capitalized earnings approach discussed later is a version of this technique. As with the discounted future returns approach discussed later, one needs to select a particular cash flow or income measure, such as gross revenues. One also needs to select the “other variable”—number of years’ billings, P/E ratio, and the like—that will link the business being valued to other businesses.
Direct comparison techniques serve as a quick way of estimating business value, with little need for extensive estimation. However, because the comparison typically reflects an average of other businesses, this technique does not do a good job of incorporating distinctive features of the business being valued.
The paybackThe number of periods management must wait before the accumulated positive cash flows from an investment exceed the initial cost of the investment project plus any negative operating cash flows. for an investment is the number of periods management must wait before the accumulated positive cash flows from the investment exceed the initial cost of the investment project plus any negative operating cash flows. Investments are considered acceptable when the payback period is less than some predetermined time period, for example 3 years. Here is the computation:
|Cash flow year 1:||−$15,000 (with the beginning investment, $115,000 still left to recover)|
|Cash flow year 2:||$50,000 ($65,000 still left to recover)|
|Cash flow year 3:||$60,000 ($5,000 only left to recover)|
|Cash flow year 4:||$60,000|
|Cash flow year 5:||$60,000|
In this example, the payback occurs at about 3 years and 1 month. Many people do not consider payback to be a discounted cash flow technique because it does not take into account the time value of money. This is not entirely true. A short payback period, say, for example, 2 years, reflects the importance of dollars received in the short term and thus the time value of money.The payback approach is related to the hyperbolic discounting phenomena. There appears to be psychological as well as economic reasons behind the fact that people prefers a reward today rather than wait for a substantial reward. Studies have found that people sometimes use average annual discount rates of over 300% over the course of 1 month and over 100% over a 1-year horizon. They ask people whether they prefer $100 today rather than $200 next month. See Noor (2009). The payback approach does not take into account cash flows that are outside of the payback threshold and they do not take into account the magnitude of the cash flows. Amazon is now a viable business but early investors did not consider the payback to be an important tool for deciding whether to invest in Amazon. This is a normal situation for many start-ups where positive cash flows do not occur until many years in the future. Discounted cash flow approaches incorporate the importance of distant cash flows and the magnitude of the cash flows.
Discounted Future Returns
Perhaps the most common, and conceptually best, technique for business valuation is calculation of the present value of expected future returns from the business. Although present-value computations are easy, determining the relevant inputs is not. Choices need to be made for:
- the type of future return to be measured (income or cash flow);
- estimates of the future amounts;
- an appropriate discount rate;
- the time period for the analysis; and
- the estimation of a terminal value.
We consider each of these areas.
Definition of Future Return
Numerous measures of future return are available to the business valuation analyst. Although cash flow measures are the most common, the analyst must still decide on a particular cash flow measure to use. One possibility is cash flow from operationsReflects the cash impact of all operating activities during a time period., which reflects the cash impact of all operating activities during a time period. Others use free cash flow, a term for which different definitions exist.
The most common definition of free cash flowCash flow from operations minus cash investments in new assets needed to maintain operations. is cash flow from operations minus cash investments in new assets needed to maintain operations. A less common definition is cash from operations minus cash investments in new assets needed to maintain operations minus debt repayments (this measure is designed to approximate cash available to the new owners).
Other analysts use income rather than cash flow measures. There are many variations here as well: net income as conventionally measured by accounting; earnings before taxes (EBT); earnings before interest and taxes (EBIT); earnings before interest, taxes, depreciation, and amortization (EBITDA); and the like. In some cases, especially if a minority investment is being evaluated, expected dividends is the relevant measure of future return.
Estimating Future Returns
Estimating future returns is a difficult task. Often the starting point is past returns, perhaps adjusted for unusual and nonrecurring items that have occurred. Knowledge of the business, industry, economic conditions, and other factors must be brought to bear.
One important task is to separate the expected future returns from the business in its present form from the expected future returns under the guidance of the new owner. Often, the efforts of the new owner will be more influential in determining future success than continuing the same uses of assets already in place. Because the business valuation is usually being conducted to establish a selling price, the buyer should not pay the seller for the buyer’s anticipated improvements in the business.
Another consideration is whether to conduct the analysis on a constant dollar basis or to estimate revenue and cost increases resulting from inflation. Whichever is chosen, the discount rate should be selected in a consistent manner, as discussed in the next section.
Although discounting expected future returns is a conceptually sound approach to business valuation, it is often not used due to the practical difficulties of implementing it. We need projected returns for several years into the future, and such estimates can be highly speculative.
Choice of Discount Rate
Many considerations enter into the selection of a discount rate. First let us consider the focus of the analysis. If the analyst employs return to all invested capital, then a discount rate appropriate to the entire capital structure should be chosen. This rate is usually called a weighted average cost of capital, because it includes costs for both debt and equity capital. In contrast, a return to equity capital focus calls for an equity-based discount rate. Following the well-known capital asset pricing model of finance, this rate includes at least two components: a risk-free rate and a risk premium, reflecting both the risks of general economic conditions and the risks of the specific business and industry. The beta β coefficient is the typical measure of risk premium used.
Next we consider adjusting for growth or inflation. When the estimates of future returns reflect inflation, then a discount rate that includes an inflation component applies. If future returns are estimated on a current (constant) dollar basis, then the inflation component should be subtracted from the discount rate. For example, suppose that an appropriate discount rate, including inflation, is determined to be 25%. The analyst uses this rate to discount estimated future returns that include inflation-based growth in revenues and costs (nominal dollars). On the other hand, if estimated future returns are based on current (constant) dollars, and the inflation assumption is 4% annually, then a discount rate of 21% (=25% minus 4% inflation adjustment) should be used to discount the current-dollar future returns. To express this another way, if the future dollar amounts in the valuation analysis reflect future prices and costs, the discount rate should include the inflation component. If the future dollar amounts are based on current prices and costs, reflecting no growth or inflation, the discount rate should exclude the inflation component.
These two discounting approaches do not provide exactly the same answer, but they are close enough. Given the many assumptions that go into a valuation calculation, the slight difference is usually deemed acceptable. For example, assume that the annual cash flow is currently $300,000. An 8-year time horizon is used for the analysis. It is estimated that cash flows will grow by 5% annually. A discount rate of 15%, including growth, is deemed appropriate. The present value of $300,000 annually discounted at 10% (15% minus the 5% growth assumption) and the present value of the growth-adjusted cash flows discounted at 15% are shown in Table 11.1 "Comparison of Present Values With and Without Growth".
Table 11.1 Comparison of Present Values With and Without Growth
|Year||Projected annual cash flow without growth ($)||Present value of cash flow without growth at 10% discount rate ($)||Projected annual cash flow with 5% growth ($)||Present value of cash flow with 5% growth at 15% discount rate ($)|
When multiyear analysis is used, a growth or inflation factor should be considered in some way. If growth is completely ignored in the above example, the present value of a $300,000 annual cash flow discounted at 15% would be approximately $1,350,000. If growth is expected, ignoring it clearly understates the value of the business. Of course, if future declines in cash flows are expected, indicating a business with initial appeal but little staying power, ignoring the expected negative growth would overstate the business value.
As seen in the above example, a positive growth assumption can either be built into the cash flow estimates, or incorporated by a reduction of the discount rate. Either approach will increase the business value relative to making no adjustment for growth.
The two present values in Table 11.1 "Comparison of Present Values With and Without Growth" are approximately the same, differing by 2%, which may be more precise than the cash flow estimates themselves or the discount rate selection. Nonetheless, one could easily find the precise discount rate and use that. If one accepts 10% as the correct rate without growth, then the correct rate with 5% growth that would discount the cash flows with growth (fourth column above) to the $1,600,476 present value turns out to be 15.50%. Similarly, if one accepts 15% as the correct rate with growth, then the correct rate without growth that would discount the constant cash flows (second column above) to the $1,628,604 present value turns out to be 9.52%. But for most purposes, the process illustrated above is sufficient.
Most of the literature on the weighted average cost of capital is based on information from public capital markets. Recently, work has been done to try to establish a private cost of capital approach.See Slee and Paglia (2010). They identify five different capital markets for private firms: bank lending, asset-based lending, mezzanine financing, private equity, and venture capital. Median rates of returns for these markets (first quarter 2010) were found to range from 6.8% for bank lending to 38.2% for venture capital financing.
Selection of Time Period for Discounting
The analyst who uses a discounted future returns approach must determine how far into the future to project. The general answer is as far as possible, keeping in mind that the uncertainty of the estimates increases as they get further away. Because a business is usually assumed to be a going concern, returns are presumed to continue indefinitely. Thus one could assume that returns continue forever. Alternatively, the analyst could limit the analysis to a fixed time period, say 10 years. In this case, one makes specific annual projections for 10 years and estimates a terminal value of the business at the end of that period.
Although estimates of future returns, or of terminal value, become more speculative the further in the future they are, the effect of discounting mitigates the increased uncertainty. For example, at a discount rate of 20%, $1,000 in year 10 contributes only $161 to the present value, and $1,000 in year 20 contributes only $26 to the present value.
When we assume that future returns will continue forever in equal amounts, we have a perpetuityWhen we assume that future returns will continue forever in equal amounts.. The present value is given by:Present value of ordinary perpetuity = Constant annual return/Discount rate
For a discount rate of 20%, the present value is five times the annual return ($5 = $1/0.2). As shown in Table 11.2 "Impact of Time on Present Value ", about 60% of the present value occurs in the first 5 years, and about 84% in the first 10 years. Returns in later years have relatively little impact on the present value.
Despite the conceptual soundness of the discounted future returns method, the subjectivity of future return estimates is a major deterrent to its use. Parties to the negotiations will likely disagree over the assumptions employed in arriving at the estimates. As a result, business valuation often employs a conceptually similar approach that appears to avoid future estimation. This approach is known as capitalized earnings.
We saw that the discounted future returns method computes a present value based on applying a discount rate to the estimated returns of a number of future time periods. The capitalized earnings approachPresent value = Amount of return to be capitalized/capitalization rate., on the other hand, computes a present value based on applying a capitalization rate to a single amount of present or past returns, as follows:
Table 11.2 Impact of Time on Present Value
|Period||Present Value of $1 at 20%||Cumulative Present Value||Percent of perpetuity value|
|Note: Annual payments assumed to occur at the end of year.|
This formula is equivalent to the present value of a perpetuity discussed above.
What amount of return should be capitalized? First, as discussed previously, any measure of return can be used—a cash flow measure, an income measure, or even revenues or dividends. Second, the return measure may be based on past, present, or even future data. Examples include the following:
- Return for the past 12 months or most recent fiscal year
- An average return, either simple or weighted, for some number of past years
- A normalized current or average return, excluding unusual or nonrecurring items
- A forecast for the current period or a future period.
Most commonly, the use of present returns, or an average of past returns, appears to avoid the estimation problem. But one cannot really avoid estimation. To base a present value on current or past returns implicitly assumes the continuation of such returns in the future.
The capitalization rateThe relevant discount rate minus the assumed rate of growth (or decline) in future returns. is the relevant discount rate, discussed above, minus the assumed rate of growth (or decline) in future returns. As an example, suppose last year’s net income of $200,000 is the amount to be capitalized, that we decide on a relevant discount rate of 20%, and that we expect 3% earnings growth. The capitalized value of the company is:
|Present value||= Amount of return to be capitalized/capitalization rate|
|= $200,000/(0.20 − 0.03)|
On the other hand, if we anticipate a 3% earnings decline, the capitalized value is:
|Present value||= Amount of return to be capitalized/capitalization rate|
|= $200,000/(0.20 + 0.03)|
A capitalization rate for equity returns is the inverse of the familiar P/E ratio commonly cited for publicly traded companies, and thus is sometimes called an earnings–price (E/P) ratio. For example, a company selling at 17 times earnings has an effective capitalization rate of 5.88% (0.0588 = 1/17). In selecting a capitalization rate for a specific business, one could use E/P ratios of reasonably similar public companies as guides. However, when valuing small nonpublic companies, lower P/E ratios (higher E/P ratios and capitalization rates) are typically appropriate, to allow for increased risk. It is not uncommon for small nonpublic companies to sell for 3–10 times earnings.
Capitalizing Excess Earnings
A widely used variation of the capitalized earnings method is called the capitalization of excess earningsHybrid variation of capitalized earnings method that reflects the concept that earnings derive from both the tangible assets and intangible assets of the business.. This hybrid method reflects the concept that earnings are derived from both the tangible assets and intangible assets of the business. Earnings from tangible assets are assumed to be relatively constant from one firm in an industry to another, whereas earnings from intangible assets may vary widely. The method proceeds as follows:
- Estimate the value of net tangible assets
- Estimate the earnings attributable to the tangible assets, perhaps by multiplying the value of the tangible assets by the average industry return
- Subtract this amount from total reported earnings; the difference is excess earningsDifference between the earnings attributable to the tangible assets and the reported earnings., the amount above what is explained by the company’s tangible assets
- Capitalize the excess earnings.
The value placed on the business has two components:Business value = Net tangible assets + Capitalized value of excess earnings
Because we tend to consider earnings attributable to intangibles to be more risky than earnings attributable to tangible assets, we tend to use high capitalization rates (low multiples).
Table 11.3 Capitalization of Excess Earnings ($)
|Value of net tangible assets||350,000|
|Reported earnings of the company||50,000|
|Earnings attributed to tangible assets = $350,000 × 0.10||35,000|
|Capitalized value of excess earnings = $15,000/0.25||60,000|
|Estimated value of company||410,000|
When we calculate negative excess earnings, the business is still presumed to be worth the value of its net tangible assets and we make no reduction for apparent negative intangibles.
For example, suppose a company reports earnings of $50,000 and net tangible assets of $350,000. Average industry earnings are 10% of net tangible assets, and we decide to capitalize excess earnings at 25%. The value estimate for the business is $410,000, as shown in Table 11.3 "Capitalization of Excess Earnings ($)".
The excess earnings method, like much of business valuation, has its foundation in materials promulgated by the Internal Revenue Service. Revenue Ruling 68–609 sets forth a so-called formula method, as follows:
The question presented is whether the “formula” approach, the capitalization of earnings in excess of a fair rate of return on net tangible assets, may be used to determine the fair market value of the intangible assets of a business. The “formula” approach may be stated as follows:
A percentage return on the average annual value of the tangible assets used in a business is determined, using a period of years (preferably not less than five) immediately prior to the valuation date. The amount of the percentage return on tangible assets, thus determined, is deducted from the average earnings of the business for such period and the remainder, if any, is considered to be the amount of the average annual earnings from the intangible assets of the business for the period. This amount (considered as the average annual earnings from intangibles), capitalized at a percentage of, say 15 to 20 percent, is the value of the intangible assets determined under the “formula” approach.
The percentage of return on the average annual value of the tangible assets used should be the percentage prevailing in the industry involved at the date of valuation, or (when the industry percentage is not available) a percentage of 8 to 10 percent may be used.
The 8 percent rate of return and the 15 percent rate of capitalization are applied to tangibles and intangibles, respectively, of businesses with a small risk factor and stable and regular earnings; the 10 percent rate of return and 20 percent rate of capitalization are applied to businesses in which the hazards of business are relatively high.
The above rates are used as examples and are not appropriate in all cases.…
The past earnings to which the formula is applied should fairly reflect the probable future earnings. Ordinarily, the period should not be less than five years, and abnormal years, whether above or below the average, should be eliminated. If the business is a sole proprietorship or partnership, there should be deducted from the earnings of the business a reasonable amount for services performed by the owner or partners engaged in the business.…
The “formula” approach should not be used if there is better evidence available from which the value of intangibles can be determined.…
Because of the extensive guidance given in Revenue Ruling 68–609, many business valuation analysts follow it closely, even though it contains many cautions and qualifications, especially in performing valuations for tax purposes. This approach has come to be known as the Treasury MethodFollowing the extensive guidance given in Revenue Ruling 68–609..See Pratt et al. (1993) for an expanded discussion of the excess earnings method.
Valuation Premiums and Discounts
After initially estimating the value of a business, that estimate may be adjusted upward (premium) or downward (discount) to reflect other factors related to the ownership interest in question. For example, a controlling interest in a business is worth more on a per-share basis than a minority interest, as the holder of a controlling interest has authority over business decisions, whereas the minority interest holder does not. This section briefly examines some common premiums and discounts.For an extended discussion of premiums and discounts, see Pratt (2001).
Business valuations typically begin with a base value, using techniques applicable to a broad range of businesses. A premium or discount is an upward or downward adjustment to this base value, to reflect some different characteristics of the particular business being considered. These characteristics are reflected in various ways. If one uses a discounted cash flow approach to valuation, a higher or lower discount rate could reflect the special characteristics. Alternatively, the analyst could adjust the initial valuation estimate upward or downward for specific features of the business. Knowing how to identify and quantify premiums and discounts is one of the specific skills of a business valuation expert. The following situations can increase or decrease the discount premium:
- Control premium: The buyer acquires a controlling interest—usually defined as more than 50% of the voting power—in the acquired company. Because of all the powers a controlling owner has, a controlling ownership interest is clearly worth more than a noncontrolling interest. These premiums can be in the 30–50% range.
- Minority interest discount: A minority interest discount, also known as a discount for lack of control, is the logical opposite of a control premium. If the ability to exercise control commands a premium, the lack of that ability is worth less.
- Strategic acquisition premium: Sometimes the acquisition of a business may be important from a strategic perspective. For example, an acquisition may complement the existing product line, broadening the geographic market, ensure a source of supply, or eliminate a key competitor, for a specific buyer.
- Lack-of-marketability discount: Publicly traded equity shares have a high degree of liquidity—they can be readily converted into cash at close to prevailing prices. Because investors value liquidity, a negative factor exists when the investor lacks the ability to sell on short notice at a market price. Studies report that thinly traded stocks realized a 30–50% price decline when the brokerage firm that was their sole market-maker went out of business.Pratt (2001), p. 79. Studies of restricted stock of public companies that itself cannot be publicly traded find discounts for the lack of marketability ranging from about 20% to 70%.Pratt (2001), chapters 5–9. Ownership interests in nonpublic companies almost always are discounted for the lack of marketability.
- Key person discount: Some acquisitions include an arrangement for the key person(s) to join the new company for a period of time. In other cases, the key persons do not accompany the acquisition, perhaps due to death or retirement. When the key person does not continue with the business, attributes such as the loyalty of customers, suppliers, or employees may be lost, as well as the key person’s particular business skills. Research studies and court cases find the key person discount to typically be in the range of 5–10% in public companies, and 10–25% in private companies.Pratt (2001), Chapter 12 "Developing a Business Plan".
Discounts may be applied to base business valuations for factors other than those described earlier. One possibility is a discount for contingent liabilitiesReflecting potential future claims resulting from past business activities that will become the responsibility of a buyer., reflecting potential future claims resulting from past business activities that will become the responsibility of a buyer. Such contingent liabilities involve potential litigation such as product liability, potential environmental claims, or potential tax adjustments for prior years. Because these liabilities are situation-specific, the valuation analyst must look sharply for them!
The above discussion indicates that discounts are more frequent than premiums. After achieving a base valuation, the analyst considers adjustments for the various factors discussed above. Note that the impact of these factors can be incorporated into the base analysis—for example, by adjusting the estimates of future income or cash flows—or can be reflected as an adjustment to the base value calculation. However incorporated into the business valuation analysis, discounts can have a large effect on the ultimate value.
