Performance
Pay for Performance
In recent years, much attention has been paid to
the suitability of CEO compensation among U.S.
firms. Of particular concern are whether total com-
pensation packages are too large, whether they en-
courage “excessive” risk taking, and whether they
are merited given the performance of the company.
This last issue is known as “pay for performance”
and gets at the question of how closely compen-
sation is correlated with the results the executive
generates.
There is considerable debate as to whether pay
is actually correlated with performance in U.S.
companies, with evidence to support both sides.
On the one hand, many elements of the compensa-
tion package are explicitly linked to performance
targets. For example, the annual bonus is awarded
based on an executive’s ability to achieve objectives
that are established at the beginning of the year.1
The size of the bonus directly scales in proportion
to the executive’s success in these areas. Also, CEOs
receive a significant portion of their compensation
in the form of equity awards (stock options and re-
stricted stock). The value of this compensation is
directly tied to share price and, in the case of stock
options, has zero value if the stock price is below
what it was on the grant date. The structure of these
payments indicates that there must be at least some
pay for performance.2
On the other hand, there have been a consider-
able number of large payments made to executives
whose companies have not performed particularly
well. For example, in 2007, Robert Nardelli (CEO
of the Home Depot) received a severance package
of $210 million, even though he resigned under
pressure from shareholders who were frustrated

with the company’s performance during his six-year
tenure.3
Richard Fuld (CEO of Lehman Brothers)
sold stock awards worth almost $200 million and
Angelo Mozilo (CEO of Countrywide) almost
$500 million, none of which they were required to
repay through “clawbacks” when their companies
collapsed in the financial crisis of 2008.4
Measuring Pay for Performance
In discussing pay for performance, the business me-
dia often highlights payments made to an executive
in a given year. This measurement, however, is mis-
leading for two reasons: 1) it involves compensa-
tion payouts that accrued over a number of years,
and 2) it is not framed in terms of the shareholder
value created during the executive’s tenure.5
For this reason, it is more instructive to examine
the relation between CEO “wealth” (measured in
terms of equity ownership through stock and op-
tions) and stock price returns. One way to make
this assessment (and a method favored by academ-
ics) is to measure the dollar change in CEO wealth
over small percentage changes in the stock price.
Based on a sample of 4,000 publicly traded U.S.
companies, the average (median) CEO stands to
gain roughly $58,000 in wealth for every 1 percent
increase in stock price. Among the largest 100 com-
panies, this figure approaches $640,000.6
A potentially more informative method is to
consider the change in executive wealth over larger
changes in stock price (after all the CEO is hired
to do more than increase the stock price by 1 per-
cent). An easy way to do so is to plot the percentage
change in the expected value of the CEO’s equity
portfolio against percentage changes in stock price
ranging from -100 percent to 100 percent. The 0

percentage point on the x-axis is based on CEO
wealth at prevailing market prices and the -100
percentage point is where the value of equity goes
to zero. By graphing this data and comparing these
results to direct competitors or peer firms, observers
can better understand the relative risk and reward
being offered. Of particular note is the “convexity”
of the payout curve. For example, a manager who
is rewarded predominantly in restricted stock or
only holds stock will see a change in wealth that
is essentially linear (low convexity) and coincides
one-for-one with the change in wealth of the aver-
age shareholder. By contrast, a manager who is re-
warded predominantly in stock options (especially
those with tranches of stock options with different
exercise prices) will see a change in wealth that has
a much steeper payout curve (high convexity) and
promises significant wealth for superior perfor-
mance.7
Payout curves with high convexity may en-
courage more risk taking, while payout curves with
low convexity may encourage less risk taking. This
can be good or bad, depending on the strategy of
the organization.8
As an example, we can consider the relation be-
tween pay and potential performance for a series of
direct competitors:
• Regulated utilities: If the stock price of South-
ern Company increases by 100 percent, the
CEO of the company’s Georgia Power division
will realize a 235 percent increase in “wealth” (a
ratio of 2.35). By comparison, the ratio at Ex-
elon’s ComEd division is 1.23. Compensation at
Southern Company therefore seems to encour-
age more risk taking. Under what circumstances
is it appropriate for a public utility to engage in
risky activities (see Exhibit 2)?
• Food companies: The CEO of General Mills has
convexity in his compensation of 2.98, while the
CEO of Kraft has convexity of 1.18. The CEO
of General Mills, however, was appointed to the
position during the year. While it can be appro-
priate to use options to help a CEO build wealth
in the company at a faster rate, will a more ag-
gressive compensation structure impact compa-
ny strategy and risk (see Exhibit 3)?
• Pharmaceutical companies: The CEOs of John-
son & Johnson and Abbott Laboratories have
higher convexity in their compensation (2.26
and 2.13, respectively) than the CEOs of Pfizer
and Merck (1.78 and 1.67). Does a diversified
healthcare model require more risk taking than a
pure-play pharmaceutical model (see Exhibit 4)?
While it is difficult for outside observers to deter-
mine whether these payout functions are appropri-
ate, this is the type of analysis that the compen-
sation committee can review to make a reasoned
assessment of whether compensation contracts are
providing appropriate incentives for performance,
and gauge their potential to encourage “excessive”
risk taking.9
These are also key inputs for analysts
attempting to make a judgment about future cash
flows and risks associated with a company.
Why This Matters
1. The current debate on pay for performance is
characterized by heated rhetoric with little con-
crete analysis to inform conclusions. Measuring
the relation between change in CEO wealth and
shareholder returns is one method shareholders
and stakeholders can use to determine whether
compensation contracts are appropriate.
2. While it is reasonable for a CEO to increase
wealth at a faster rate than shareholders (because
executives are asked to make strategic decisions),
it is not clear what the ratio of this relationship
should be. Should it be 1.5 times, 2.0 times, 2.5
times, etc? In all likelihood, the ratio should be
determined in the context of the company’s in-
dustry, competitive positioning, and risk appe-
tite, as well as the size of the executive’s equity
holdings and tenure. 

According to a confidential survey conducted in 2005 by a major
HR consulting firm, the top measures used to determine the annual
bonus include profit measures (earnings per share, EBITA, net in-
come, operating income, and pretax profit), return measures (return
on capital, return on assets, and return on equity), cash flow mea-
sures (cash flow, economic value added, and working capital), and
other measures (sales growth, customer satisfaction, product/service
quality, safety, and employee satisfaction). Typically, there is also a
subjective component for “individual performance.”

This assumes that shareholders measure performance in terms of
value creation and that executive decisions impact stock prices.

For example, James Kilts, CEO of Gillette, came under fire for re-
ceiving a severance package worth $185 million following the sale of
Gillette to Procter & Gamble in 2005. Less noted was the fact that
Kilts increased the value of Gillette by over $20 billion during his
four-year tenure, delivering annual returns of 14 percent compared
with negative 0.6 percent for the S&P 500. Sources: Graef Crystal,

ing terms are reduced by 30 percent to adjust for potential early
exercise or termination. Source: Equilar compensation and equity

7
For simplicity, we use the term “convexity” to mean the percentage
return on the CEO’s equity portfolio for a 100 percent change in the
stock price. This is taking a bit of liberty with the pure mathematical
definition of convexity.
8
Since 2006, companies have had to provide detailed information
on each tranche of options held by named executive officers. Previ-
ously, options outstanding were pooled together. Disaggregation in
the disclosure allows us to precisely plot out the changes in value of
each, based on prevailing market prices.
9
Obviously, risk taking can be either good or bad for shareholders.
Firms are in business to take appropriate risk and generate the re-
quired returns for shareholders. Risk taking is negative when the risk
assumed by investment, financing, and operating decisions is exces-
sive in relation to the potential return.

Note: The graph shows the expected change in CEO wealth, given a change in company stock price. While shareholders
realize a 1-for-1 change in wealth with stock price, CEO wealth will vary depending on the mix of compensation. Compen-
sation packages that include a heavier allocation of stock options will exhibit a steeper pay off, while those that include
a heavier allocation of restricted stock will exhibit a more linear payoff. Calculations exclude personal wealth outside of
company stock.
