Abstract
This paper examines the relation between executives’ equity-based compensation
and accounting conservatism. Since both mechanisms may mitigate the agency
problems between managers and shareholders, I hypothesize that there is a negative
relation between the proportion of equity-based compensation to executives and the
level of conservatism. Using a large sample of US firms during the period 1993-2012,
I find that the coefficient of interaction on the ratio of executives’ equity-based to
total compensation and accounting conservatism is negative and significant. Further, I
divide the whole sample period into four parts: 1993-2001, 2003-2005, 2006-2008,
and 2009-2012. The results of period 2003-2005 and 2006-2008 are consistent with
my hypothesis: the asymmetric timeliness of earnings declines with managerial
proportion of executives’ equity-based compensation. However, the outcomes of
period 1993-2001 and 2009-2012 are negative but not significant. The reason might
be that accounting standard at that time is associated with adoption and shareholders’
understanding of managers’ incentives plan. Besides, the trend of stock market may
bring about an unobvious effect. The results are robust after controlling for the
investment opportunity set and additional tests.

1. Introduction
The purpose of this study is to investigate whether executives’ equity-based
compensation and the structure of executives’ compensation has an effect on firm’s
accounting conservatism policy. According to prior research, executives’ equity-based
compensation may help in aligning the interests of managers and shareholders. An
incentive compensation system for executives or to give them stock options can be
used to partly alleviate the agency problems (Ahmed et al. 2002; Jensen and Meckling
1976). Meanwhile, accounting conservatism is another way to help mitigate the
agency costs by asymmetric timeliness of earnings (Watts 2003). Therefore, I predict
that equity-based compensation to executives will decrease the need of reducing
information asymmetry using conservative accounting.
In this paper, following Murphy (1999) specification, executives’ pay packages
contain four basic components: a base salary, an annual bonus tied to accounting
performance, stock options, and long term incentive plans (including restricted stock
plans and multi-year accounting-based performance plans). Generally speaking,
executives’ compensation can be classified into two types: one is earning-based
compensation including basic salary and annual bonus; the other is equity-based
compensation including stock options and restricted stock.
Regarding conservatism, accountants traditionally express it by the rule
2
“anticipate no profits, but recognize all losses”. Basu (1997) redefines the
conservatism principle in accounting as the more timely recognition in earnings of
bad news than good news. Watts (2003) interprets “differential verification” as the
greater the conservatism, the greater the difference in degree of verification required
for gains versus losses. He further provides alternative explanations for conservatism,
namely accounting regulation, taxation, shareholder litigation, and contracting. Under
the contracting explanation, conservative accounting is a means of mitigating the
agency problems between managers and shareholders. It is a mechanism increases the
efficiency of contracts between managers and shareholders. Even more, Iyengar and
Zampelli (2010) indicates that conservatism limits earnings management
opportunities and ties executive compensation contracts more closely to accounting
performance. Even though Watts (2003) reveals that such contracts are a main factor
behind the demand for accounting conservatism, there is little empirical research that
examines the relation between executives’ compensation contracts and accounting
conservatism. Most of previous research focuses on debt contracts (Ahmed et al., 2002;
Zhang, 2008; Ball et al., 2008; Beatty et al., 2008) or on earning-based compensation
contracts. However, the composition of executive pay in the U.S. changes
dramatically during the last two decades. The trend toward equity-based pay appears
to be spreading to the rest of the developed countries. Consequently, the objective of
3
this paper is to provide a long term perspective on the relation between executives’
equity-based compensation and accounting conservatism.
The remainder of this paper is organized as follows: Section 2 discusses related
research and develops the hypothesis. Section 3 describes research design and the
measurement of executives’ equity-based compensation, accounting conservatism,
and variables used. Section 4 outlines the sample selection criteria and reports
descriptive statistics for the variables used. Section 5 presents the empirical results of
accounting conservatism. Section 6 discusses sensitivity analysis. Section 7 draws
conclusion.

2. Related Research and Hypothesis Development
Separation of corporate’s ownership and corporate’s control at the turn of the
twentieth century gives rise to the agency problems between managers and
shareholders (Berle and Means 1991). Executives first take into consideration their
own goals and personal reputation instead of firm profits. Managers have incentives
to transfer wealth to themselves from shareholders due to limited horizons and limited
liability. Conflicts of interest between managers and other parties to the firm arise
because information asymmetry, managers have more information than the
stakeholders and effectively control firms’ assets but generally do not have a
significant equity stake in their firms. Thus, one solution to the agency problem is
linking management compensation and shareholders’ equity. During the last two
decades, equity-based pay has increasingly become part of the compensation
packages. Following Murphy (1999) specification, executives’ pay packages contain a
base salary, an annual bonus, stock options, and restricted stock. Equity-based
compensation in this paper contains stock options and restricted stock:
Stock Options give employees the option of buying company stock at a
pre-specified time with the set price that the stock options program grants. Options
give executives a greater incentive to act in the interests of shareholders by providing
a link between realized compensation and company stock price performance. They
5
have no value at the time of issue. If the stock price of the corporation rises, stock
options holders can make a profit by buying the stock below the fair market price.
However, if the company stock price sinks below the option set price, they are
essentially worthless to the employee.
There are always some restrictions apply to the stock options. Like employees
can’t leave the firm before vesting, thus also providing retention incentives. Finally,
stock options encourage executives risk taking, which can mitigate problems with
risk-averse executives.
Restricted Stock is granted to employees in a process known as vesting rather
than buying by employees. Shares earned build up until they reach the vesting period.
Restricted stock help increase employee loyalty and encourage employees to stay with
the company long enough to reach the vesting.
The purpose of equity-based compensation mentioned above serves to increase
employee motivation, improve employee loyalty, and reduce turnover in the
workforce. There is also a considerable amount of empirical evidence that suggest
equity holdings motivate executives to raise profitability and increase shareholder
value. Establishment of an incentive compensation system serves to more closely
identify the manager’s interests with those of the outside equity holders. (Jensen and
Meckling 1976). Effective managers’ compensation structure plays a significant role
6
in protecting shareholders’ wealth. Well-designed equity plans better align top
executives’ interests with shareholders. It strengthens the link between executives’
pay and corporate performance and motivates sustainable, or long-run, value creation
(Hall 2003). Nagar et al. (2003) find that managers with more equity-based
compensation have incentives to mitigate the managerial disclosure agency problem
since their interests are more aligned with shareholders’. Armstrong et al. (2010)
provide evidence that executives with greater equity incentives may lower frequency
of accounting irregularities and reduce improper financial reporting. In sum, those
researches are consistent with the notion that equity-based compensation for
executives plays a role in mitigating the agency problem between managers and
shareholders.
Watts (2003) demonstrates that conservatism can be another method of reducing
the information asymmetry between managers and shareholders. Without a
verification requirement, executives can overstate future cash flows; maximize their
payments under earning-based compensation plans; and possibly lead to negative net
present value investments by the firm. LaFond and Watts (2008) imply that
information asymmetry generates demands for conservatism. Conservatism can
reduce information asymmetry by restricting the manager’s ability to manipulate
financial reporting through disclosing negative information faster in form of earnings.
7
As mentioned above, accounting conservatism and equity-based compensation
may both help in aligning the interests of managers and shareholders. Therefore, I
want to evaluate the influence of equity-based compensation to accounting
conservatism policy. Whether the amount or proportion of equity-based compensation
given to executives influences the level of conservatism?
Hypothesis: There is a negative relation between the proportion of
equity-based compensation to executives and the level of conservatism.
This paper adopts Basu’s model to assess accounting conservatism. Conditional
conservatism is defined as the imposition of stricter verification standards for
recording good news as gains than for recording bad news as losses. Under
unconditional conservatism, the book value of net assets is understated because of
predetermined aspects of the accounting process(Beaver and Ryan 2005). Ball and
Shivakumar (2005) state that “an unconditional bias of unknown magnitude
introduces randomness in decisions based on financial information and can only reduce contracting efficiency. In contrast, the conditional form of conservatism can
improve contracting efficiency. The agency issues associated with unconditional
conservatism are likely to disorder its’ relation with executives’ equity-based
compensation. ” Consequently, the test of hypothesis is restricted to the association
between equity-based compensation and conditional conservatism.

3. Research Design
3.1. The measure of executives’ compensation
The sample of executives’ compensation is based on Standard & Poor's
Execucomp database during the period 1993-2012. In 1992, the Securities and
Exchange Commission (SEC) began asking firms to disclose more detailed
information on executives’ compensation in their proxy statements. Reporting rules
on executive compensation do change over time, the FAS123(R) changed the
reporting requirements of the SEC DEF14A form in 2005. Companies with fiscal year
end after Dec 2005 have to adjust to new reporting requirement. Equity-based
compensation has to be expensed and be reflected in the financial statements based on
fair value of the awards. Prior to 2006, the variables called
“OPTION_AWARDS_BLK_VALUE” and “RSTKGRNT” are used to represent
executives’ equity-based compensation. The “OPTION_AWARDS_FV” and
“STOCK_AWARDS_FV” columns are essentially comparable between the old and
new reporting formats after 2006.
3.2. The measure of accounting conservatism
I adopt Basu’s model to measure accounting conservatism. Under conservative
accounting, earnings capture bad news faster than good news because of the
asymmetric standards of verification of losses and gains.

EPSBPt
1= β

where
EPSBPt
1 is the earnings per share for firm i in fiscal year t (EPSBit) divided bythe price per share at the beginning of the fiscal year (Pit-1).
R is the stock rate of return of the firm, measured by compounding 12 monthly
CRSP stock returns ending the last day of fiscal year t.
D is a dummy variable=1 if R < 0, = 0 otherwise.
The coefficient β3 measures the level of asymmetric timeliness of conservatism
and it is expected to be positive and significant
3.3. Empirical model
In order to test hypothesis, I use the following model to investigate the relation
between executives’ equity-based compensation and accounting conservatism:

10
where
ECOMP is the ratio of top five executives’ equity-based compensation,
including stock options and restricted stock, to top five executives’ total compensation
in fiscal year t. Total compensation for the individual year, comprised of the following:
salary, bonus, other annual, total value of restricted stock granted, total value of stock
options granted, long-term incentive payouts, and all other total. Valuation is based on
the grant date fair value reported by company or using standard and poor’s
Black-Scholes methodology before 2006.
Leverage is total debts divided by total assets at the beginning of the fiscal year t.
It’s a variable to control conservatism demands of debt holders. Ahmed et al. (2002)
find accounting conservatism mitigates conflicts between bondholders and
shareholders over dividend policy. Conservatism benefits lenders through a timely
signal of default risk.
Growth is the ratio of market value of equity to book value of equity at the
beginning of the fiscal year t to control for the effect of beginning composition of
equity value on future asymmetric timeliness.The Basu’s measure is affected by the
beginning composition of equity value. Asymmetric timeliness appears to measure
conservatism more efficiently when estimated cumulatively over several periods.
(Roychowdhury and Watts, 2007)
11
Size is natural log of total assets at the beginning of the fiscal year t. The firm's
degree of reporting conservatism is affected by firm size. Firm size influencing
conservatism is information asymmetries. It is positively correlated with the relative
amount of public information which reduces information asymmetry between
investors (Givoly et al., 2007; LaFond and Watts, 2008).
The Appendix A of this paper provides more detailed definition and items of
variables from each database.
The coefficient of ECOMP*R*D (β7) measures the relation between executives’
equity-based compensation and accounting conservatism with regard to bad news. If it
is consistent with the prediction of hypothesis, β7 would be negative.

4. Sample Selection and Descriptive Statistics
The sample of executives’ compensation is obtained from S&P ExecuComp
database over the period 1993 to 2012. In addition to requiring compensation data, I
require firms’ accounting data on Compustat and returns data on CRSP to conduct my
empirical analyses. Table1 Panel A summarizes my sample selection procedure. I
obtain the initial sample of 37,603 observations on ExecuComp database for
1993-2012. Next, I merge Compustat and ExecuComp, excluding companies without
complete accounting data or executives’ compensation information, and remains in
37,569 observations. Afterward, I combine returns data on CRSP with Compustat and
ExecuComp, which result in a sample of 23,328 observations. Finally, after deleting
outliers of each variable at 0.5% level to improve the quality of regression, the sample
is reduced to 22,302 observations. Panel B reports sample classification by fiscal year
and by industry which determined by NAICS (North America Industry Classification
System) code. It informs that there are sufficient data in each year, and the firms range
over Manufacturing, Finance and Insurance and so on.

Table2 reports the descriptive statistics for the variables used in this study. The
descriptive statistics in Table2 indicates the mean of fiscal stock returns is 0.146100,
which is generally consistent with those of previous studies. The mean and median of
logT5EBC and ECOMP are 6.068635, 6.378178 and 0.381032, 0.386873,
respectively.
The Appendix B of this paper provides descriptive statistics for stock options
(using “OPTION_AWARDS_BLK_VALUE” and “OPTION_AWARDS_FV”),
restricted stock (using “RSTKGRNT” and “STOCK_AWARDS_FV”), logT5EBC,

Table3 reports the correlation matrix among the variables. It shows that although
EPSBPt1 is positively correlated with R (0.2141), it is negatively correlated with D
(-0.2247). Those are consistent with Basu’s results, indicating that reported earnings
reflect at least a portion of the information reflected in returns.

5. Empirical Results
Table4 tests conservatism using Basu’s regression. Under the definition, the
coefficient of R measures the timeliness of earnings with respect to good news. In
contrast, the coefficient of R*D measures the “incremental” timeliness of earnings
regarding bad news. Therefore, β3 is predicted to be positive and significant. In this
analysis I focus on the coefficient of R*D because it measures the degree of
accounting conservatism.
The result is consistent with Basu’s model under conservatism. β3 is positive
(0.6342652) and significant, which means that earnings reflect “bad news” more
quickly than “good news”. Besides, the intercepts is positive (0.0335077) which
implies that unrealized gains is postponed to future periods.

In the regression, β1 measures earnings timeliness with respect to good news and β3 measures the asymmetric timeliness with respect to bad news. β5, β9, β13, and β17
measure the association of β1 with ECOMP, Leverage, Growth, and Size, respectively.
β7, β11, β15, and β19 measure the association of β3 with ECOMP, Leverage, Growth,
and Size, respectively. The coefficient of ECOMP*R*D (β7), measuring the relation
between proportion of executives’ equity-based compensation and accounting
conservatism with regard to bad news, is predicted to be negative.
Within the sample period 1993-2012, Table5 represents that coefficient on R*D
is significantly positive (0.425), and the coefficient on ECOMP*R*D is significantly
negative (-0.0525). These results suggest that as ratio of executives’ equity-based
compensation to total compensation declines, earnings become more asymmetrically
timely in recognizing bad news.
18
Turning to control variables, they are in accordance with the theoretical
prediction. The coefficient of Leverage*R*D is positive and significant as expected,
indicating that firms with greater leverage are more asymmetrically timely in
recognizing bad news. The coefficient of Growth*R*D and Size*R*D are both
significantly negative which is consistent with extant empirical evidence. There is
relatively more public information for larger firms (Banz 1981). Firm size is
positively correlated with the relative amount of public information which reduces
information asymmetry between investors generating a negative association with
conservatism.

To provide more specific relation between equity-based compensation and
accounting conservatism, I divide the whole sample period into four parts: 1993-2001,
2003-2005, 2006-2008, and 2009-2012 owing to following reasons:
There has been a dramatic change in both the level and composition of executive
pay in the U.S. during the last two decades. The level of compensation has increased
substantially in 1990s, and the increase was attributed to the grant of stock options.
During the early 1990s, stock options became a single largest component of
compensation (Murphy 1999). I set the first period from 1993-2001 due to a small
decrease in stock options granted to executives since 2002. Corporate accounting
scandals including those at Enron, WorldCom and other companies, have been linked

to escalation in option grants. Stock options have been criticized on giving managers a
strong incentive to risk chasing investments and misleading shareholders about the
true condition of their companies (MaDick 2003). To avoid bias analysis, it is
necessary to exclude year 2002 from the sample.
Next period is 2003-2005. As of fiscal year 2006, executive compensation is
reported under new filling requirements. Companies with fiscal year end after Dec
2005 have to adjust to new reporting requirement FAS123(R). This statement focuses
primarily on accounting for share-based payment transactions exchanging employee
services. Equity-based compensation has to be expensed and be reflected in the
financial statements based on fair value of the awards. Prior to FASB 123(R),
companies could expense options using the intrinsic value method and often recorded
no associated expense on their Income Statement. Before 2006 the variable collected
from Execucomp called “OPTION_AWARDS_BLK_VALUE” and “RSTKGRNT”
are used. The OPTION_AWARDS_FV and STOCK_AWARDS_FV columns are
essentially comparable between the old and new reporting formats after 2006. They
both represent the value of options/restricted stock that were awarded during the
indicated fiscal year. The one difference is that under the old format, the Black
Scholes values for options were calculated by S&P (since companies were not
required to report them); under the new format, Black Scholes values are reported by
22
the company. Hall and Murphy (2002) suggest that models of firms’ choices of equity
compensation methods should include the accounting considerations. Carter et al.
(2007) support the assertion that accounting affects the design of executive
compensation. On the basis of previous studies, year 2006 might be a watershed for
executives’ structure of compensation.
The third and fourth periods are 2006-2008 and 2009-2012. Subprime mortgage
crisis in 2007 and the collapse of Lehman Brothers and problems of Merrill Lynch,
AIG, Freddie Mac, Fannie Mae… in late 2008 almost brought down the world’s
financial system. The financial crisis is considered by many economists the worst
financial crisis since the Great Depression of the 1930s, which might affect the
analysis results. Therefore, I divide the year after 2006 into those two parts.
Appendix C reports the descriptive statistics for the variables used in this study
of different periods.

The coefficient of ECOMP*R*D in period 1993-2001 is negative but not
significant. Thanks to Jensen & Murphy (1990) demonstrating that the compensation
of top executives is virtually independent of their performance, peoples’
understanding of the link between CEO compensation and company performance has
improved substantially. They argue that pay-performance sensitivity in managerial
compensation contracts is too low to provide executives with incentives to act in the
interests of shareholders. The most powerful link between shareholder wealth and
executive wealth is direct stock ownership by the CEO. However, CEO holdings as a
percentage of corporate value compare to prior decades have declined. Figure1 shows
that the mean of ECOMP has grown in the 1990s and reached 40% (the sample mean
of ECOMP is 38%) in 1998. Nevertheless, the empirical result is insignificant. I think
the first reason might be that equity-based compensation for US executives has just
become increasing popular in 1990s. Second, companies generally do not treat
options as an expense, either at time of grant or exercise, on company financial
statements at that time. In 1992, SEC’s new disclosure rules, comprising with firms,
would only report “numbers” of option grants. It suggests that shareholders may be
difficult to understand manager’s compensation policy.

Figure 1 The mean of ECOMP
Period 2003-2005 and 2006-2008 are consistent with my hypothesis that the
coefficient of ECOMP*R*D is significantly negative at 0.05 levels. These results
suggest that the asymmetric timeliness of earnings declines with managerial
proportion of executives’ equity-based compensation. Executives’ equity-based
compensation plays a role in accounting conservatism policy. In 1995, SFAS 123
encourages firms to calculate stock-based compensation expense based on the fair
value of options granted, but permits entities to continue using APB 25. Following the
financial reporting scandals of firms such as Enron and WorldCom, dozens of firms
began to announce their intention to recognize SFAS 123 expense voluntarily. Firms
that are more active in the capital markets are more likely to reap benefits from such a
signal (Aboody et al. 2004). Executives’ compensation structure will change through
the time and accounting considerations. Prior to implementation of FAS123(R), firms
make decisions based on the perceived costs rather than the economic costs, they
27
grant more options than they would. It is important to note that firms appear to
substitute away from stock options towards other forms of performance-based pay as
opposed to salary because of FAS123(R) (Hayes et al 2012). Murphy (2012) also
illustrates that the use of restricted shares gradually substitute for stock options to top
executives. According to Hall and Murphy (2003), incentives are maximized through
granting nontradable restricted stock rather than options, and it also affects managerial
incentives to engage in risky investments. Consequently, the trends can support period
2003-2005 and 2006-2008 are consistent with my hypothesis that the coefficient of
ECOMP*R*D is significantly negative.
The coefficient of ECOMP*R*D in period 2009-2012 is negative but not
significant. Although options accounted for only 20 percent of total pay, while
restricted stock had ballooned to 34 percent by 2010 (Murphy 2012), catastrophic
corporate failure in late 2008 draws shareholders’ attention on options which
incentivize managers’ excessive risk seeking behavior. On the other hand, benefits of
options will backfire in bear market (Hall and Murphy 2003). According to CenFIS
reports, the financial crisis in September and October 2008 was accompanied by
stunning decreases in stock prices. The S&P 500 fell 48 percent in a little over six
months. Executives and employees at many companies hold worthless options in
response to financial crisis. The effects mutually may cause the relation between the
28
proportion of equity-based compensation to executives and the level of conservatism
in significant.
Table7 reports the results which replace ECOMP with logT5EBC to assess my

6. Sensitivity Analysis
6.1. The effect of the investment opportunity set (IOS)
Smith and Watts (1992) find that firms’ investment opportunity set (IOS), the
extent to which firm value is determined by growth options and intangible assets, is
related to their financing, dividend, and executive compensation policies. Skinner
(1993) also mentions that the structure of management compensation agreements will
vary across firms as a function of the IOS. Managers of firms with relatively more
growth opportunities are likely to be allowed more decision making discretion
because these managers have better information about the firm’s investment
opportunities than shareholders. Smith and Watts predict that growth firms are more
likely to use incentive compensation plan that tie management compensation to
measures of firm performance.
Roychowdhury and Watts (2007) provide insights into the link between the IOS
and accounting conservatism. US GAAP prohibits upward revaluations of assets,
changes in the value of growth options, and capitalization of certain internally
generated intangibles. Consequently, subsequent declines in the value of these
unrecorded assets are also not recognized. Earnings of firms with high growth options
are not very informative, in other words, low observed conservatism when changes in
firm value are driven by changes in the value of growth options and intangible assets.
32
In summary, the IOS has a positive association with managers’ equity-based
compensation and negative association with accounting conservatism. Thus, it is
possible that variation in the IOS induces a negative relation between executives’
equity-based compensation and accounting conservatism. I try to control the effect of
IOS. As investment opportunities are typically unobservable by outsiders, a common
practice is to rely on proxy variables. According to Adam and Goyal (2008),
market-to-book assets ratio (MBA ratio) has the highest information content with
respect to investment opportunities.

In addition, in robustness check, I use the sample which their economic
losses/gains located in less than 25 percentages (Q1) or more than 75 percentages (Q4)
to test whether the relation between executives’ equity-based compensation and
conservatism are more sensitive. I predict that accounting conservatism can be more
observable when firms whose returns situated in the two ends of the bell curve are
included in the same period. Table9 Panel A expresses return’s quartile of four
periods. In period 2003-2005, I choose the firms whose returns are less than
0.0111017 or more than 0.3983957. In period 2006-2008, firms whose returns are less
than -0.2743965 or more than 0.1802682 are selected. Panel B uses the same
regression to test the hypothesis. I find that the result of period 2006-2008 is more
significant.

6.3. Results excluding NAICS 22&52, First 6 NAICS without 22&52
Political pressures may constrain top executive pay levels in utilities and finance
industry. Therefore, Table10 tries to examine the results after excluding NAICS 22
Utilities and 52 Finance and Insurance. Furthermore, it provides the results are robust
of the first 6 biggest NAICS without utilities and finance.
Further, the empirical result is a monotonic function after using ECOMP2 to test.
6.4. Results of stock options
According to Lafond and Roychowdhury (2008), their measures of managerial
ownership exclude shares granted in options. They consider shares granted in options
have potentially different incentive effects than shares owned. Therefore, I try to
examine the results of stock options of my analysis. In Table11, the results are robust
after undertaking a similar analysis as in Table 6 but use S as an explanatory variable.

7. Conclusion
Lafond and Roychowdhury (2008) find that conservatism as measured by the
asymmetric timeliness of earnings declines with managerial ownership. They use the
percentage of shares held by the CEO (or the top five highest paid executives) in the
form of direct ownership at the beginning of the fiscal year. But, the coefficient of
shares granted in options separately is insignificant because they consider shares
granted in options have potentially different incentive effects than shares directly
owned. To extend their research, I try to focus on executives’ compensation policy
and value of those stock options and restricted stocks on grant date. First, the CEO of
a large firm with a tiny fractional ownership but an equity stake worth tens of millions
of dollars might worth much than the CEO of a small firm who owns a significant
share of company stocks. Dollar holdings are likely to be the more important
incentive measure in a wide variety of situations (Baker and Hall 1998). Second, I
include the value of share options because I think when the firm grants an incentive
plans to managers will presume they can achieve the goals. Third, executives’
compensation structure will change through the time and accounting considerations.
Changes in accounting standard are associated with adoption or modification of
managers’ incentives plan. I desire to investigate the effect of executives’
compensation policy to firm’s accounting conservatism policy in different periods.
