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

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

(-0.26)

21

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
