atic risk. It is important, however, to avoid a double counting, since adjustments
for size can often implicitly include adjustments for other operating attributes.
13. While the amount of industry risk premia data available from Ibbotson
Associates is expected to grow over time, many analysts in the valuation com-
munity are not yet comfortable with the direct application of industry risk pre-
mia adjustments. However, analysts can consider this new empirical evidence
where the subject falls within one of the Ibbotson-defined industries and there is
a need to assess industry risk, that may not be captured in the build-up method.
14. Caution should be used whenever a methodology assigns specific numerical
adjustments to various categories of specific company risks in the build-up or
CAPM rate. Due to the subjective nature of the numerical assignments for each
category, one can easily get trapped upon cross-examination in testimony as to
whether it might be considered reasonable for each of the factors to be, say,
half a percent higher or lower, thereby causing a significant change in the
resulting capitalization or discount rate being developed.
15. The format and content of an analytical framework for analyzing unsystematic
risk will vary considerably depending on the nature of the assignment and the
depth of analysis required. However, the articulation of the analyst’s thought
process by use of diagnostic tools can be a means of competitive differentia-
tion, whether the tools are included in the final report or only in engagement
work papers.
16. The betas published by different sources can display different results due to dif-
fering time periods, methodologies, and adjustments. Therefore, care should be
exercised.
17. A good source of information for determining industry capital structures can
be found in the Ibbotson Associates Cost of Capital publications. If the guide-
line public company method is being used, the public companies can be a
source of capital structure components.
18. Since traditionally derived discount and capitalization rates are cash flow rates,
not earnings rates, an upward subjective adjustment would have to be made to
convert the rate for application to earnings.
19. It is important to recognize the increasingly “noisy” nature of public company
reported valuation multiples including P/E. As indicated in the August 21, 2001,
Wall Street Journal,

many public companies have moved away from using
GAAP earnings for the E of the P/E. They may instead utilize other earnings
measures, such as operating earnings before extraordinary items, core earnings,
and even pro forma earnings. Each of these revised definitions of earnings
allows reporting entities to exclude certain one-time, exceptional, special, or
noncash expenses, and, in turn, the net income of the enterprise is higher.
According to the Wall Street Journal article, more than 300 of the 500 entities
making up the S&P 500 now exclude some ordinary expenses as defined by
GAAP from the operating earnings numbers provided to investors and analysts.
20. Arbitrage pricing theory (APT) is not widely used in business valuation assign-
ments for cost of capital determinations due to the unavailability of usable data
for the components of the model.
