ABSTRACT
We examine the effect of compensation consultants on CEO pay. Using a sample of 292 firms in 2006 randomly selected from ExecuComp, we find that compensation consultants are associated with higher salaries, consistent with the hypothesis that consultants help boards of directors justify excessive CEO pay. However, we also find that the use of a consultant is associated with lower bonuses and total compensation. In addition, we find that when consultants are used, CEO pay has greater sensitivity to performance, particularly negative performance, consistent with consultants devising pay schemes that hold CEOs more accountable for poor performance. Finally, we find that compensation committees are more forthcoming in their disclosure of executive pay when a consultant is used. Together our findings suggest that executive pay schemes reflect (more) efficient contracting when consultants are involved in the compensation process. Perhaps as a result, we find that compensation committees provide more details of such pay packages when they have hired a consultant. Overall, our results are more consistent with the efficient contracting hypothesis than with the rent extraction hypothesis.

1. Introduction
This study examines whether and how compensation consultants influence the
level and form of executive pay. While agency theory provides guidance on optimal
contracting schemes and prior empirical literature extensively studies contracting design
(see for example Core and Guay, 1999 and Hall and Murphy, 2002), little is known about
the role of compensation consultants in the design of incentives schemes or how
compensation consultants influence executive pay levels. This question has become
particularly important as the use of compensation consultants has risen over the past few
years (Higgins, 2007). We shed light on this issue by examining the relationship between
the use of compensation consultants and the level and design of CEO compensation for a
sample of firms from the S&P 1500, which represents the largest publicly traded U.S.
firms.
Boards of directors and compensation committees are rarely knowledgeable about
the economic determinants of optimal compensation design. At the same time, the lack
of a generally accepted benchmark for evaluating executive pay packages sets the stage
for frequent criticism. For example, Crystal (1991) argues that executive compensation is
excessive and insulated from actual performance. As such, boards of directors and
compensation committees frequently hire compensation consultants to help guide them
through the complex issues regarding executive pay. Stronger governance rules have
also caused boards to rely on the advice of independent consultants (Guerrera, 2006).
Compensation consultants provide specialized knowledge of executive
compensation design on multiple dimensions. They advise the firm regarding accounting
and tax regulations that pertain to executive compensation design. In addition,
2
compensation consultants often provide information on industry-wide pay practices
through survey data and guide the selection of comparable (peer group) firms to aid the
firm in setting competitive pay levels.1 More generally, compensation consultants may
help the firm design compensation schemes that more closely align the interests of
managers with shareholders. Such a role is consistent with the efficient contracting
hypothesis, which states that executive compensation is optimally determined (on
average) to maximize shareholder value.
Despite the potential benefits of compensation consultants advising the board of
directors and compensation committee, some view their role with great suspicion. Critics
allege that consultants help disguise and justify excessive executive pay (Bebchuk and
Fried, 2006; Crystal, 1991; Morgenson, 2006a). The critics argue that compensation
consultants enable executives to extract rents from the firm. For example, consultants
may handpick peer groups to help justify higher salaries. Similarly, compensation
consultants may help design compensation schemes that provide greater pay without
requiring greater performance, potentially by identifying easily attainable targets and/or
providing compensation schemes that are not closely linked with performance.
According to this view, consultants help executives extract wealth from the firm at the
shareholders’ expense. Such a role is consistent with the rent extraction hypothesis,
whereby executives use their power to extract rents from shareholders.
The goal of this study is to examine the effect that compensation consultants have
on the design of executive compensation packages. Specifically, we examine the
association between the use of compensation consultants and executive compensation

practices, including the level of compensation and the sensitivity of pay to performance.
Our findings shed light on the role of compensation consultants in the design of executive
compensation plans and provide evidence on whether compensation consultants aid the
firm in devising more efficient contracting schemes or whether they enable executives to
extract rents from the firm.
To address these issues, we utilize the recent disclosure requirement of the
compensation committee in the firms’ proxy statement. Under the new Securities and
Exchange Commission rules (effective for filings on or after December 15, 2006),
companies must provide a “Compensation Disclosure and Analysis” (CD&A) section in
their annual proxy statement. Among other information, firms must disclose which, if
any, compensation consultant the firm retains to advise the compensation committee.
Utilizing these disclosures, we hand collect this and other data for a sample of 292 firms
randomly selected from the ExecuComp database.2 Using this sample of firms, we find
that 85% use a compensation consultant, suggesting that the use of consultants is
widespread. We also find that, of the firms that hire a consultant, the top five consultants
represent 70% of the sample.
To address the issues described above, we examine the level and design of
executive compensation across firms that do and do not retain a compensation consultant.
In addition, we test for differences between firms that hire one of the top five consultants
and firms that hire another consultant. Our univariate analysis indicates that clients of
compensation consultants pay their CEOs higher salaries, bigger bonuses, and provide
them with greater amounts of equity, especially when they employ a top five consultant.
2 As discussed further in Section 3, our sample consists of firms randomly selected from the ExecuComp database. We are in the process of hand-collecting data for all December fiscal year end firms on ExecuComp with 2006 data.

After controlling for other economic determinants of executive pay, we continue to find
that the use of a consultant is associated with greater CEO salaries. However, we find
that annual bonus payments and total direct compensation are not significantly different
for clients of compensation consultants after controlling for economic determinants.
The evidence on the relation between compensation consultants and pay-for-
performance sensitivity is consistent with the efficient contracting hypothesis.
Specifcally, we find that after controlling for performance, clients of compensation
consultants pay significantly smaller bonuses, but we find weak evidence that the bonus
is more sensitive to return on assets. When we also consider equity payments, we find
stronger evidence that clients of compensation consultants (in particular for top five
consultants) grant lower values of cash and equity payments. At the same time, we find
that total direct compensation is more sensitive to performance for clients of top
compensation consultants.
We extend our analysis of pay for performance sensitivity (PPS) by allowing the
relation to vary for positive and negative performance, as in Gaver and Gaver (1998).
The results indicate that the increased sensitivity of compensation to performance for
firms that hire consultants is driven by higher PPS for loss making firms; we find no
significant differences in PPS based on the use of consultants when return on assets is
positive. Overall, our findings suggest that compensation schemes of firms that retain
compensation consultants provide greater baseline salaries but also more powerful
incentives by more closely linking pay with performance, in particular when performance
is poor. This combination suggests that the higher base salaries are compensating CEOs
for the additional compensation risk that is imposed on them.
5
To further address the issue of whether compensation consultants help executives
disguise and justify excessive executive pay, we investigate the level of disclosure in the
compensation discussion and analysis. After controlling for a set of disclosure
determinants, we find firms that retain a compensation consultant provide longer CD&A
reports in the annual proxy statements. This evidence is consistent with clients of
compensation consultants providing more thorough discussions of the compensation
schemes.
Overall our results suggest compensation consultants provide expertise to
compensation committees and aid them in setting CEO pay in a manner that more closely
aligns the interests of executives with shareholders. We find limited evidence that
compensation consultants help justify excessive and inappropriate pay in the form of
greater salaries. At the same time, we find that the bonus and total direct compensation
(including equity payments) are more sensitive to firm performance, and to negative
accounting earnings in particular, when the firm retains a consultant. These results are
generally strengthened for clients of top compensation consultants. However, we are
continuing to expand our sample and to validate our conclusions and further explore the
determinants of equity incentives. We also plan to explore the extent to which the
independence of the compensation consultant influences compensation contracts using
various independence metrics we have collected from the proxy statements.
This study contributes to the compensation and governance literatures on the role
of governance and board characteristics in achieving efficient contracting schemes by
investigating an important advisor to the board, the compensation consultant. Because of
prior limited disclosure, ours is among the first to study the role of compensation
6
consultants and the effect they have on executive pay using a broad sample of firms. Our
study also provides additional evidence on the more general debate regarding executive
compensation practices, which can help distinguish between the rent extraction and
efficient contracting hypotheses. Evidence on this debate is important, not least because
the controversy has moved to a global forum with non-US executive pay packages
coming to resemble their US counterparts (Fabrikant, 2006; Grant et al, 2006).
Our paper continues as follows. In Section 2, we provide background information
and develop our hypotheses regarding the association between the use of compensation
consultants and executive compensation. Section 3 discusses data sources, variable
construction, and our research design. Section 4 presents the results of our empirical
tests, and Section 5 concludes the paper.
2. Background and hypothesis development
2.1 Background
Consultants have been advising firms about executive compensation for several
decades. U.S. public companies frequently employ outside consultants to provide input
into the executive compensation process. Compensation consultants generally assist
compensation committees in two ways. First, they provide expertise on compensation-
related issues. This expertise covers various legal and tax-related aspects of executive
compensation practices, as well as pay practices appropriate for organizational changes
such as mergers, acquisitions, spinoffs, and restructurings. Consultants have extensive
knowledge about recent developments in pay practices and different forms of
compensation and benefits. Thus, they can provide expert guidance to the compensation
7
committee in tailoring packages for its executives (Brancato, 2002). Second,
compensation consultants typically have access through proprietary surveys to more
detailed information about industry pay practices than is publicly disclosed. These
surveys allow consultants to provide the compensation committees with detailed analyses
of peer group compensation practices. Indeed, data from selected peer group firms are
frequently used as the starting point for determining compensation packages.3
However, until recently, there has been little public information available about
consultants’ usage or role within the firm, likely due to the fact that firms were not
required to disclose the use of compensation consultants. This lack of transparency has
contributed to suspicions about whose interests they really serve: shareholders or
executives (Crystal, 1991; Morgenson, 2006a). Critics contend that compensation
consultants merely provide justification for overly-lucrative executive pay packages.
Compensation consultants can aid the executive in extracting rents by managing survey
data and opportunistically selecting peer groups that make their client’s performance
appear better and their pay packages appear smaller than they actually are (Crystal,
1991).4 In addition, consultants who are also hired by management to provide other
services such as actuarial and other compensation benefits may be under considerable
pressure to recommend higher pay packages for executives in order to retain their other,
potentially more lucrative, consulting business with the client firm (Creswell, 2007,
Morgenson, 2007).
3 Bizjack, Lemmon and Naveen (2007) report that 96 of 100 firms examined used peer groups in determining management compensation. 4 This type of strategic selection of benchmarks has been documented in other settings. Byrd et al. (1998) and Soffer (1998) document that firms strategically select a benchmark to maximize relative performance measures in proxy statements while Schrand and Walther, 2000 find that managers strategically select the prior-period earnings amount that is used as a benchmark to evaluate current-period earnings.
8
In response to increased concerns over executive pay, the Securities and
Exchange Commission requires companies to provide a “Compensation Disclosure and
Analysis” (CD&A) section in their annual proxy statement. The CD&A requires
numerous disclosures by the Compensation Committee, including which, if any,
compensation consultant was used in the setting of compensation for top executives.5 In
addition, firms must disclose whether a peer group of firms was used, and if so, name the
firms in the peer group. These new disclosures allow us to provide systematic evidence
on the role of compensation consultants.
2.2 Hypothesis development
The use of compensation consultants can be explained within an optimal
contracting framework (“efficient contracting hypothesis”) on the grounds that they
contribute useful information and considerable expertise to the design of compensation
packages. Shareholders can benefit if using a consultant results in compensation
packages for top executives that more closely link executive pay to firm performance
compared to the compensation packages that committees acting on their own would have
devised. If this characterization of their role is correct, then we expect various properties
of executive compensation to be more closely aligned with shareholders’ interests when
firms retain a compensation consultant.
It is possible, however, that the true role of compensation consultants is to
validate excessive pay packages that are not in shareholders’ interests (“rent extraction
5 Item 407(e)(3)(iii) of Regulation S-K “requires companies to disclose the role compensation consultants played in the decision-making process, and we asked a number of companies to do so. In particular, we asked companies to more specifically disclose the nature and scope of a consultant’s assignment and material instructions the company gave it.”

hypothesis”). A CEO that is able to exercise power over the board of directors and the
compensation committee has the opportunity to extract additional compensation from the
firm.6 Under this view, compensation committees are either persuaded or provided
incentives to recommend excessive compensation. In doing so, they may utilize
compensation consultants to justify to shareholders and outsiders the excessive levels of
compensation. Hiring compensation consultants provide captive boards with the
opportunity to attribute compensation design to the advice of experts and the pay
practices of peer firms. Consistent with this argument Wade, Porac and Pollock (1997)
find firms that pay their CEOs larger base salaries are more likely to cite the use of
consultants and surveys in justifying executive pay to their shareholders.
Compensation consultants frequently provide other, and potentially more
profitable, services to the client firm beyond advice about executive compensation. In
such situations, compensation consultants will lack independence and be less likely to
provide objective recommendations. Instead, they are likely to curry the CEO’s favor by
recommending excessive pay packages in order to secure and protect these other lucrative
assignments (Crystal, 1991, Morgenson, 2006a). Such activities can take place even
when the compensation committee is composed of truly independent directors who are
trying to act in the best interests of shareholders.
Consultants can inappropriately influence executive pay through two methods.
First, executives are typically evaluated on multiple aspects of firm performance, such as
earnings per share, stock returns, sales growth, etc. Consultants can justify higher pay
packages by strategically emphasizing those measures of firm performance where the

firm has performed well (or is more likely to perform well). Second, consultants can
opportunistically select the peer groups that are used to calibrate executive pay levels.7
Compensation consultants can skew the selection of the peer groups toward larger firms
and firms with relatively high CEO salaries in order to justify higher pay at the client firm
even if the CEOs performance does not warrant it (Gillian, 2001). This effect is
particularly strong when compensation committees state (as they frequently do) that they
want their CEOs’ salaries to equal the median amount of a select group of peers against
which they compete for executive talent (Morgenson, 2006b). In total, these arguments
suggest that the use of consultants will lead to even higher pay packages that are less
closely aligned with shareholders’ interests when firms hire compensation consultants
than when firms do not.
If the optimal contracting hypothesis is descriptive, then the use of consultants
will lead to more efficiently designed pay packages that more closely align executives
with shareholders’ interests. Because salaries are generally fixed payments that do not
provide incentives, under the efficient contracting hypothesis, ceteris paribus, CEO
salaries will be lower in the presence of compensation consultants. On the other hand, if
the rent extraction hypothesis is descriptive, then compensation consultants will be
associated with higher salaries. To distinguish between these predictions, we test the
following hypothesis:
H1: There is a negative (positive) association between CEO salaries and the use of compensation consultants under efficient contracting (rent extraction).
7 While we currently test this issue by examining compensation schemes, we intend to more directly investigate issues associated with peer group selection in future versions.
11
This hypothesis also applies to other forms of compensation such as annual bonus
and equity payments. However, these other forms of pay are generally associated with
performance or incentive targets. To address this issue, we focus the discussion of
incentive-related compensation in the following hypothesis.
A primary objective of executive compensation is to link executive pay to firm
performance, thereby aligning the executive’s wealth with shareholders’ wealth. In order
to accomplish this, CEO compensation packages typically include variable cash pay
(bonus) and equity-based pay in the form of shares and stock options. These types of
compensation schemes increase pay-for-performance sensitivity by more directly linking
executive wealth to firm performance. Under the efficient contracting hypothesis, we
predict that the presence of a compensation consultant is associated with greater pay-
performance sensitivity, thereby achieving greater alignment between executives and
shareholders.8
Increased pay-for-performance sensitivity imposes risks on executives and
encourages executive effort. However, risk- and effort-averse executives prefer large
fixed compensation packages, and variable pay that depends on easily attained targets.
To the extent indulged, both preferences will result in compensation that is less sensitive
to firm performance than shareholders would prefer. Therefore, compensation
consultants that help executives extract rents from the firm may do so by designing
8 Variable pay imposes risks on the CEO since the ultimate payoff depends on firm performance and the performance measure does not perfectly capture effort. As a result, risk-averse CEOs prefer less contingent compensation, ceteris paribus. Ideally, the compensation committee optimally trades-off the incentive benefits of performance-related pay with the costs of imposing risk on the executive. We assume that due the consultant’s expertise in this area, firms that employ them are better able to manage this trade-off. Hence, the end result will be higher PPS at firms that engage compensation consultants compared to firms that do not.
12
compensation schemes with easily attainable targets, resulting in weaker pay-
performance sensitivity.
The rent extraction hypothesis predicts that CEOs of firms with compensation
consultants provide compensation schemes that are less sensitive to firm performance. In
contrast, the efficient contracting hypothesis predicts that compensation consultants help
the firm design compensation schemes that are more sensitive to performance. To
distinguish between these theories, we examine the sensitivity of the annual
compensation to firm performance and test the following hypothesis:
H2: There is a greater (smaller) association between CEO pay-performance sensitivity and the use of compensation consultants under the optimal contracting (rent extraction) hypothesis.
Our final hypothesis examines the relation between compensation consultants and
the amount of information disclosed in the compensation disclosure and analysis
(CD&A) report. Under the efficient contracting hypothesis, the compensation consultant
provides expertise in designing a compensation scheme that benefits shareholders.
Accordingly, we predict that the compensation committee chooses to provide more
information in the CD&A regarding the nature and design of executive compensation
when they are advised by a consultant. Alternatively, if the compensation committee aids
in executive rent extraction, we predict that the compensation committee will be less
forthcoming in the CD&A about the details of the compensation contract. Less
information will likely help shield them from criticism by shareholders and other
outsiders. We measure the degree to which the compensation committee is forthcoming
13
about executive compensation (or the quantity of information disclosed in the CD&A) as
the number of words in the CD&A. Using this proxy, we test the following hypothesis:
H3: The quantity of information disclosed in the CD&A is positively (negatively) associated with the use of compensation consultants under the optimal contracting (rent extraction) hypothesis.
3. Research Design
3.1 Sample selection and data sources
Our initial sample consists of 371 firms in the S&P 1500 randomly selected from
ExecuComp. Because the new Compensation Disclosure and Analysis requirement was
effective for filings on or after December 15, 2006, our sample is approximately one-
third of ExecuComp firms with December fiscal year ends. We begin with one-third of
ExecuComp firms since our analysis requires extensive hand-collection of data.9 Of
these 371 firms, 12 are missing proxy statements for 2006, 64 do not have executive
compensation data on ExecuComp, and three are missing market value of equity. Thus,
our final sample consists of 292 firms.
From firms’ CD&A disclosures in the 2006 proxy statements, we determine what,
if any, compensation consultant the firm retains. We also collect information on the
degree of participation by the CEO in setting pay. Finally, from these proxy statements,
9 We are currently in the process of expanding the sample to all ExecuComp December fiscal year end firms with compensation data in 2006.
14
we collect the size of the compensation committee, the number of times it met during the
year, and the total number of words in the CD&A.10
We obtain performance data, firm size, and the market to book ratio from
Compustat and CRSP. We obtain CEO compensation data from ExecuComp.
As reported in Table 1 Panel A, our sample firms are generally profitable with an
average ROA of 5.3% in 2006. In addition, these firms have average book-to-market of
0.44. As reported in Table 1 Panel B, our sample firms are somewhat concentrated in
durable manufacturers (21%), financial institutions (18%) and utilities (10%). No other
industry group comprises more than 10% of sample firms. As reported in Table 1 Panel
C, approximately 85% (247 firms) of the sample reported using a compensation
consultant in 2006. Of these firms, 70% (171) use one of five main consultants: Towers
Perrin (the consultant employed by the largest percent of the sample), Mercer Human
Resources Consulting, Hewitt Associates, Frederick W. Cook, and Watson Wyatt. This
distribution is consistent with that of a study of Russell 3000 firms by the Corporate
Library (Higgins, 2007) and suggests that our results can be generalized to a larger
population of firms.
3.2 Research design
For all of the tests that follow, since there is some concentration in our sample
among five compensation consultants, we measure an indicator for clients of other
consultants (OTHER_CONSULT) and an indicator variable that captures whether the
firm uses one of the top five consultants (TOP_CONSULT). This distinction provides
10 We intend to further explore the governance characteristics relating the independence of the board, compensation committee, and committee meetings in future work.
15
us the opportunity to refine our tests and determine the extent to which there are
differences amongst the two groups of consultants. In particular, the largest consultants
may be more likely to offer additional services (actuarial or benefits outsourcing) that the
client firms may also be utilizing. To the extent this is true and it compromises their
executive pay services, we may expect different results for these consultants.
To examine the question of whether firms’ use of compensation consultants
increases CEO pay, we estimate the following OLS model for our sample of firms in
2006:
COMPENSATIONj = α0 + α1ASSETSj + α2BMj + α3ROAj + β1TOP_CONSULTj + β2OTHER_CONSULTj + Σ αiINDj + εj (1)
where:
COMPENSATIONj = CEO Salary (ExecuComp variable Salary) for firm j in 2006, or CEO bonus (ExecuComp variable bonus and noneq_incent) for firm j, or total compensation (the sum of cash pay and the fair value of stock and option grants);
TOP_CONSULT = 1 if firm j employs a one of the consultants that are in the top 5 of the market share in our sample in 2006, 0 otherwise;
OTHER_CONSULT = 1 if firm j employs a compensation consultant, but not one of the Top 5 in 2006, 0 otherwise;
ASSETSj = Log of total assets (Compustat Data Item 6) of firm j in 2006; BMj = Book value of common equity (Compustat Data Item 6 –
Compustat Data Item 181 – Compustat Data Item 130) divided by market value of equity (Compustat Data Item 25 * Compustat Data Item 199) of firm j in 2006;
ROAj = Return on assets (Compustat Data Item 172 / Compustat Data Item 6) of firm j in 2006;
INDj = Indicator variable for industries based on Barth et al (1998).
We include variables to capture the standard economic determinants of
compensation: the log of total assets to control for firm size effects, the book-to-market
ratio to control for growth opportunities, and return on assets to control for firm
performance (Smith and Watts, 1992; Gaver and Gaver, 1993 and 1995; Core et al.,
16
1999). We include industry indicator variables using the classification from Barth,
Beaver, and Landsman (1998) to capture potential differences in compensation practices
across industries.
If the use of a compensation consultant leads to higher CEO pay, we expect β1
and β2 to be positive. Also, to the extent that the top five consultants exacerbate the
executive’s abilities to extract rents form the firm through increased salaries, we would
expect β2 > β1. At the same time, negative coefficients on the consultant indicators would
be consistent with the presence of compensation consultants being associated with lower
levels of compensation. Similarly, finding that β2 < β1 would suggest that firms with top
consultants provide lower pay than clients of other consultants.
While estimating the model above provides insight into the level of compensation
granted to the CEO, it does not shed light on the issue that compensation consultants may
help the firm provide compensation that is more sensitive to performance. To examine
the relation between firms’ use of compensation consultants and pay-for-performance
sensitivity, we estimate the following OLS model of the relation between accounting
performance and bonus compensation11:
COMPENSATIONj = α0 + α1ASSETSj + α2 BMj + α3ROAj + β1TOP_CONSULTj + β2OTHER_CONSULTj + β3TOP_CONSULTj*ROAj + β4OTHER_CONSULTj *ROAj (2) + ΣαiINDj + εj
Where the variables are as defined in Eq. (1).
Positive coefficients on the interaction of consultant with ROA (β3 and β4) are
consistent with the use of a compensation consultant leading to greater pay-for- 11 Murphy (2000) finds that 91% of firms in his sample use accounting earnings as a performance measures in bonus contracts hence we use return on assets as our performance measure.
17
performance sensitivity. If consultants aid the executive in extracting rents, we would
expect to find no relation on the interaction of consultant and performance. In addition,
the rent extraction hypothesis predicts that the compensation level is significantly larger
(β1 > 0 and β2>0) after controlling for performance. In addition, investigating the
difference between β3 and β4 provides evidence on the difference in the pay-for-
performance sensitivity across the consultant types.
We also estimate this model allowing for separate effects of positive and negative
performance following Gaver and Gaver (1998). That is, we estimate the model with
separate variables for positive performance (POS_ROA) and negative performance
(NEG_ROA) including separate interactions with the consultant indicators. If
compensation consultants design contracts with less pay-performance sensitivity, it may
be the case that such contracts either reward good performance less (in which case we
expect a negative relation on the interaction of CONSULTANT and POS_ROA) or
penalize bad performance less (in which case we expect a negative relation on the
interaction of CONSULTANT and NEG_ROA). Alternatively, positive relations would
be consistent with clients of compensation consultants providing greater sensitivity of
pay-for-performance.
Finally, to examine whether the use of compensation consultants leads firms to be
less forthcoming in their disclosures about executive compensation and test hypothesis 3,
we estimate the following regression:
WORDj = α0 + α1NO_EXECj + α2PENSIONj + β1TOP_CONSULTj + β2OTHER_CONSULTj + ΣαiINDj + εj (3)
where all other variables are defined as before and:
18
WORDj = The number of words in the CD&A for firm j in 2006; NO_EXECj = The number of executives included in the Summary Compensation
table of the proxy statement for firm j in 2006; PENSIONj = 1 if compensation for executives in firm j include a pension in 2006, 0
otherwise;
We include NO_EXEC and PENSION to control for other determinants of
increased discussion in the CD&A since more executives will require more explanation
and pensions have additional required disclosures. Positive coefficients on the consultant
indicators are consistent with consultants being associated with compensation discussion
and analyses that are more forthcoming. In addition, comparing the coefficients on the
types of consultants provides evidence on the differing relations across the consultant
types.
4. Results
4.1 Univariate analysis
Our first evidence on the relation between compensation levels and the presence
of compensation consultants is reported in Table 2, which reports the summary statistics
of the annual compensation for our sample of firms.12 We find that average CEO of
clients that retain a compensation consultant earn higher salaries than firms that do not
retain a compensation consultant. We also find that CEOs of firms that retain a top
consultant earn significantly higher salaries. We do not find a significant difference in
the mean bonus paid to the CEO of firms that retain other consultants relative to firms
12 For parity we focus our univariate analysis on the difference between clients of top consultants clients of other consultants, and firms that do not retain a consultant. In general, we find similar trends when we compare firms that retain any consultant to those that do not retain a consultant, but the differences are less significant because the sample of firms that do not retain a consultant is significantly smaller than those that do. Our multivariate analysis further explores this issue.
19
that do not retain a consultant. However, we find a significant difference in the median
bonus between the two samples. In addition, we find that clients of top consultants earn
significantly greater bonuses than both clients of other consultants and firms that do not
retain a consultant. We find similar results as those of bonus compensation when we
consider total cash compensation.
When we consider total compensation including equity payments, we find that
clients of compensation consultants earn significantly greater total compensation than
firms that do not retain a consultant on average. However, we do not find a significant
difference in total compensation between the clients of top consultants, and clients of
other consultants. Interestingly, when we separately identify the components of equity
compensation, we find that the stock compensation is significantly greater for firms that
retain a compensation consultant compared with firms that do not retain a consultant.
There is no significant difference between the stock compensation for clients of the top
consultants compared with clients of other consultants. At the same time, we do not find
a significant difference in the stock option compensation between clients of other
consultants and firms that do not retain a consultant. While we find that clients of top
consultants grant significantly greater option compensation than clients of other
consultants and firms that do not retain a consultant, we do not find that clients of other
consultants grant more options than firms that do not retain a consultant.
Overall, the results of our univariate analysis suggest that compensation
consultants help executives earn larger pay packages and clients of the top 5 consultants
earn somewhat larger cash compensation than clients of other consultants. However, we
are hesitant to make broad conclusions from the univariate analysis because the summary
20
statistics neither control for important economic determinants of compensation, nor
provide evidence on the sensitivity of the compensation to performance.
4.2 Multivariate analysis
To more directly test hypothesis 1 and 2, and provide evidence on how
compensation consultants influence the level compensation as well as the sensitivity of
compensation to performance, we estimate executive salaries as a function of economic
determinants and the presence of a compensation consultants. In addition, to distinguish
the influence of Top consultants from other compensation consultants, we separately
identify clients of the difference groups of consultants as described in Eq. (1). By
examining the influence of the five largest consultants in the market, we are able to infer
whether the relations differ for consultants that hold greater shares of the market.
Table 3 provides estimation results of the level and sensitivity of various
measures of compensation. Column 1 provides evidence on the relation between
compensation consultants and salary. The positive and significant coefficients on
OTHER_CONSULT and TOP_CONSULT are consistent with clients of consultants
paying significantly greater salaries than firms that do not retain a consultant. We do not
find a significant difference in salaries across the two consultant groups as suggested by
an F-test of β1 = β2. To provide evidence on the pay-for performance sensitivity of
salary, Column (2) provides results from testing whether the relation between salary and
performance is different for clients of compensation consultants. After allowing the
salary to vary with performance, we no longer find that compensation consultants
(regardless of type) provide greater salaries. However, we find some evidence that the
21
relation between salary and performance is greater for clients of top consultants than
clients of other consultants.
Columns 3 and 4 report results of the analysis where the annual bonus is the
dependent variable. Here we do not find evidence that clients of consultants provide
significantly different bonuses than other firms. In addition, we do not find evidence that
clients of top consultants pay their executives different bonuses than clients of other
consultants. However, after controlling for performance and allowing the relation to vary
for clients of consultants, we find firms that retain a compensation consultant grant
significantly lower bonuses than other firms (as indicated by an F-test that β1 + β1 <0). In
addition, we find that clients of top consultants provide significantly lower bonuses than
firms that hire other consultants. We do not find evidence that the bonus is more
sensitive to performance for firms that retain either type of consultant. In aggregate, the
results of the bonus analysis provide weak evidence that clients of compensation
consultants grant lower bonuses than other firms. We find similar results to the analysis
of bonus compensation when we consider total cash compensation suggesting (consistent
with the summary statistics) that bonus is a larger component of cash compensation, and
this appears to be driving the results of the total cash compensation results.
The last two columns of Table 3 present results from estimating the total
compensation including equity payments. To address the concern that equity is granted
in part to realign executive incentives with levels predicted by economic determinants as
suggested by Core and Guay (1999), we control for the residual incentives held in the
executive portfolio at the end of the prior fiscal year. Interestingly, after controlling for
economic determinants of annual compensation, we do not find that clients of
22
compensation consultants provide significantly different levels of total compensation.
However, after allowing the relation between total compensation and performance to vary
for the different groups of firms, we find that clients of top consultants earn lower levels
of total compensation, but the compensation is significantly more sensitive to
performance. In addition, we find that the sensitivity of total compensation to
performance is significantly more sensitive for clients of compensation consultants of
either type (as suggested by an F-test of β3+β4 =0). We also find that clients of top
consultants provide total compensation levels that are significantly more sensitive to firm
performance than clients of other consultants.
4.3 Positive and negative performance
Gaver and Gaver (1998) find that the sensitivity of compensation to performance
differs for positive and negative performance. To address this issue and further
investigate the sensitivity of compensation to performance in the presence of
compensation consultants, we estimate the models described above allowing the
coefficients for performance to vary for positive and negative ROA. Table 4 presents
results of the expanded estimations.
In general the results on salary are slightly weaker in that we no longer find a
difference in the relation between salary and performance for clients of the different
consultants. However, turning to the bonus compensation, we find that clients of top
consultants pay bonuses that are significantly more sensitive to negative performance
than other firms (and clients of other consultants). The results suggest that the
significantly greater sensitivity of bonus to performance found in Table 3 is a result of the
23
increased sensitivity to negative performance. Again when we consider total cash
compensation, the results are consistent with those found for the bonus relations.
Finally, when we consider the equity payments in conjunction with the cash pay
after allowing the relation on performance to vary for positive and negative returns, we
find that clients of other consultants grant significantly greater compensation than clients
of top consultants. We also find that clients of consultants grant annual compensation
that is more sensitive to performance, when the performance is negative. At the same
time, we find that clients of top consultants grant annual compensation that is more
sensitive to performance, when the earnings are positive, than clients of other consultants.
Overall, the results after allowing the relation to vary for positive and negative
earnings are broadly consistent with the main findings. However, the evidence suggests
that the increase in pay-for-performance sensitivity is primarily focused on cases where
earnings are less than zero, and less associated performance once the earnings are
positive. This finding is consistent with Gaver and Gaver’s (1998) conjecture and finding
of an asymmetric relation between compensation and accounting performance.
4.4 CD&A disclosure
Our final hypothesis relates the level of disclosure regarding compensation to the
presence of a compensation consultant. If the use of a compensation consultant leads to
more efficient compensation contracts, compensation committees are likely to be more
forthcoming about its contracts with executives. Thus, we estimate the influence of
compensation consultants using the word count of the compensation discussion and
analysis (CD&A) of the annual proxy statement as a measure of the degree to which the
24
firm is forthcoming about their compensation. Because firms with more named
executives and with executive pensions will likely have longer CD&As, we control for
these two elements in the estimation. The results of the estimation are provided in Table
5. We find evidence that clients of compensation consultants and top compensation
consultants present longer CD&As. In addition, we find that the clients of top
compensation consultants provide CD&As with significantly more words than clients of
other compensation consultants. Overall, the evidence suggests that firms that retain
compensation consultants are more forthcoming about their compensation, and clients of
top consultants are less forthcoming that clients of other consultants.
4.4 Future direction
We are collecting information on the use of consultants in the remaining sample
of 594 firms on ExecuComp with December fiscal year ends. We are also in the process
of hand-collecting compensation data for the 64 firms we were not able to include in the
current analysis. In the next version of this paper, we plan to include all 965 firms in our
analysis. In addition, we are collecting data on the types of performance measures used
to determine bonus compensation. We intend to examine whether the use of
compensation consultants is correlated with the use of a performance measure which had
better outcomes in prior years. Finally, we have collected data on the size of the
compensation committee and the number of times the committee met in 2006. We intend
to incorporate this data in the next version of the paper to consider the substitutive or
complementary role the compensation committee plays, relative to the compensation
consultants, in setting CEO pay.
25
5. Conclusions
We examine the effect that compensation consultants have on the design of
executive compensation packages. Little is known about the role of compensation
committees in the design of optimal incentives schemes or how the assistance of
compensation consultants influences executive pay. Understanding the influence of
consultants has become a particularly important question as the use of compensation
consultants, both domestically and internationally, has risen over the past few years
(Higgins, 2007).
The dominant theories about how executive compensation is determined suggest
two very different roles for the compensation consultant. Under the optimal contracting
hypothesis, compensation consultants will assist the firm in designing compensation
schemes that more closely align the interests of managers with shareholders due to their
specialized knowledge of compensation practices. Under the rent extraction hypothesis,
consultants are retained to help secure and justify excessive pay schemes that serve to
transfer wealth from shareholders to executives. Our analysis of the role of compensation
consultants provides evidence on which theory is more descriptive in practice.
Taking advantage of new SEC disclosures that require companies to disclose
whether the firm retains a compensation consultant, we identify which firms use a
compensation consultant for a sample of 292 firms randomly selected from the
ExecuComp database. We find that 85% of the firms in our sample employ at least one
compensation consultant, suggesting that the use of consultants is widespread. We then
examine the relation between the level and form of CEO pay and the use of a
26
compensation consultant. Specifically, we consider salary, bonus and total compensation,
and we examine the pay-for-performance sensitivity of CEO pay.
We find that the use of a consultant is associated with higher CEO salaries but
lower annual bonus payments and lower total direct compensation, after controlling for
economic determinants of compensation. These results provide mixed evidence in
support of the efficient contracting hypothesis. However, we find that the annual bonus
and total direct compensation (which includes equity payments) is more sensitive to firm
performance for firms using compensation consultants than for firms that do not. In
particular, we find that these contracts are more sensitive to negative performance than
positive performance, consistent with consultants devising pay schemes that hold CEOs
more accountable for poor performance. Overall, our findings suggest that the
compensation schemes of firms that retain compensation consultants provide greater
baseline salaries, while also providing greater incentives in the form of higher PPS.
To further address the issue of whether compensation consultants help executives
disguise and justify excessive executive pay, we investigate the level of disclosure in the
CD&A report. After controlling for a set of disclosure determinants, we find firms that
retain a compensation consultant provide more thorough CD&A reports in the annual
proxy statements. In total, these results suggest that executive pay schemes reflect
efficient contracting when consultants are used and, as a result, compensation committees
are willing to provide more details of such pay packages.
