INTRODUCTION
1.1 Background and Purpose
The lack of availability of reliable and verifiable estimates between managers and
investors can cause uncertainty and information asymmetry in an entity’s business environment
(Watts, 1993) Managers can use conservatism as a means to manage information asymmetry in
their private information and in their financial reporting strategies (Chaney, 2006) LaFond and
Watts (2008) state that conservatism, “is an equilibrium corporate response to mitigate the value
reduction resulting from information asymmetry between informed and uniformed investors.”
Watts (2003a) advocates that “the evidence on conservatism suggests asymmetric verifiability of
estimates is crucial to constraining manipulation and fraud” and a decrease in conservatism may
allow some managers the opportunity to generate fraud (Watts, 2006) However, in light of these
statements, the Financial Accounting Standards Board (FASB) contends that an inherent conflict
is that conservatism may also have the effect of inducing information asymmetry in the
timeliness1 of incorporating economic events in reported earnings by creating bias and noise (Givoly and Hayn, 2002) Bias and noise in the financial statements generate “soft” accounting
numbers2 (Watts, 2006; Mackintosh, 2006) which can also lead to fraud and manipulation
Trang 15“Extreme conservatism in recognizing income could produce too many false signals” (Watts,
1993)
The objective of this study is to measure the differences in the magnitude, consequences,
and methods used to calibrate accounting conservatism in regards to litigation risk, as well as
regulation and standard setting, between firms that have been allegedly accused of fraud3 and a non-fraud matched control group I specifically address whether firms with higher thresholds of
litigation risk are more inclined to use higher levels of accounting conservatism as a choice in
reducing information asymmetry One of the effects of conservatism could be the responding
change in a firm’s cost of equity capital LaFond and Watts (2008) state that information
asymmetry between equity investors creates “deadweight losses” that in turn reduce the firms’
cash flows and increase the equilibrium return on the firm’s equity Whether the role of
conservatism can mitigate the effect of an increase in cost of capital for alleged fraud firms is
examined in this context
Accounting conservatism can be measured in terms of both the balance sheet and the
income statement While there is no one conventional definition or method employed to measure
accounting conservatism, and due to it not being directly observable and difficult to calibrate at
the firm level, conservatism has been characterized by the traditional adage of “anticipate no
profits, but anticipate all losses” (Bliss, 1924) It has also been referred to as “the accountant’s
tendency to require a higher degree of verification to recognize good news as gains than to
recognize bad news as losses” regarding future cash flows (Basu, 1997) Accounting
conservatism is one factor that may provide information about earnings quality (Francis et al,
2004; Watts, 2003a) as it involves the timely recognition of bad news versus good news in
3
I use the terminology “allegedly accused” because, although the SEC’s enforcements may be issued and filed, the proceedings do not in every instance result in civil or criminal charges For example, some of the
SEC’s Auditing and Enforcement Releases (AAERs) indicate only a cease and desist order pending
restitution in the form of a settlement payment while not admitting to any wrongdoing
Trang 16earnings It is often termed asymmetric gain and loss recognition, differential timeliness, or
conditional conservatism4 (Gassen et al., 2006) Another form of conservatism, referred to as unconditional conservatism,5 involves reporting low book values of net assets, independent of losses, as often occurs with immediately expensing of intangibles (Ryan, 2006) Gassen et al
(2006) show that conditional conservatism, unconditional conservatism, and earnings smoothing
(a proxy for conditional conservatism) are theoretically diverse concepts which can yield different
earnings distributions
According to the FASB’s conceptual framework, Statement of Financial Accounting
Concepts No 2, Qualitative Characteristics of Accounting (FASB, 1980), the exploitation of
conservatism by managers may create noise or a downward bias in financial reporting.6 Consequently, the FASB has been considering eliminating conservatism from its framework in
order to achieve more “neutrality of information.” They state that in order for accounting
information to be relevant, it has to be verifiable, neutral, and contain representational
4
Conditional conservatism is often referred to as news-dependent or ex post conservatism and involves
firms writing down the book value of assets in a timely manner It includes the impairment write down of tangible and intangible assets (Qiang, 2007), goodwill, the lower of cost or market or historical value rule
in regards to inventory (Ryan, 2006), and GAAP that requires research and development expenditures to be expensed rather than capitalized
5
Unconditional conservatism is often referred to as news-independent or ex ante conservatism It involves
firms committing at inception to recognizing the book value of assets that are below their expected market values during their lives It includes the immediate expensing of internally generated intangible assets and the amortization of long-lived assets (Ryan, 2006) It can involve excess depreciation which lowers book values and reduces subsequent conditional conservatism (Qiang, 2007)
6
The FASB’s Project Update (FASB, 2005), states that conservatism/prudence should remain excluded from the qualitative characteristics of accounting information They assert that neutrality should include freedom from bias, prudence, and conservatism The FASB staff has expressed reluctance to continue to include conservatism or prudence as a list of desirable qualitative characteristics of accounting information together with neutrality The FASB Board has suggested that the notion of conservatism should be eliminated However, they stated that the FASB’s conceptual framework should note the continuing need
to be careful in the face of uncertainty In practice, the idea of conservatism has been altered from FASB’s original intention The FASB’s definition of conservatism as a prudent reaction to uncertainty does not imply that financial statements should always be pessimistic The role of conservatism is for preparers to acknowledge that risks and uncertainties are present in financial information and to adequately account for those risks in the information that is presented to decision makers
Trang 17faithfulness.7 The FASB’s Conceptual Framework relates to the hierchy of favorable accounting quality characteristics (FASB, 1980) Critics of accounting conservatism claim that it leads to an
understatement of earnings in the current period This can lead to an overstatement of earnings in
future periods by understating future expenses (Penman and Zhang, 2002) at a point in time that
managers determine “selectively fits their operating results” (Massoud and Raiborn, 2003)
While accounting conservatism in this context explains accelerated loss recognition, accounting
conservatism can also be explained in the context of delayed gains recognition (Srivastava and
Tse, 2007) Advocates argue that the elimination of conservatism could affect managerial
behavior and have economic consequences Therefore, the study of conservatism remains
relevant and important
Contemporaneous empirical evidence suggests that the trend in conservative financial
reporting has been monotonically increasing over the past 30 years in the U.S and is also evident
in other common law countries (Ball et al 2000, 2003; Givoly and Hayn, 2000) However,
during this time period, there appear to be waning and waxing period changes Watts (1993)
proposes several theories regarding the existence of conservatism He predicts that conservatism
in U.S accounting should vary with unexpected changes in legal liability Shareholder litigation
produces asymmetric information payoffs such that overstating firm assets should more likely
generate litigation costs for the firm Other theories offered for the emergence of conservatism
have been attributed to the use of financial statements in debt and compensation contracts (the
7
In Statement of Financial Accounting Concepts No 2, Qualitative Characteristics of Accounting (FASB,
1980), relevance and reliability are two primary qualities of accounting information For accounting information to be reliable, it has to provide predictive value, feedback value, and timeliness For accounting information to be relevant, it has to be verifiable, neutral, and contain representational faithfulness The FASB defines the reliability of a measure as “the faithfulness with which it represents what it purports to represent, coupled with an assurance from the user, which comes through verification, that it has representational quality.”
Trang 18contracting explanation) and the ability to defer taxation The nature of accounting regulation
and standard setting also provides support for the role of conservatism in financial reporting
While there is documented to be an increasing trend in conservatism, research has also
indicated a bias in financial reporting due to opportunistic earnings management For example,
Dechow et al (1996) characterize the majority of their fraud sample as consisting of firms that
have income/revenue overstatements and higher levels of total accruals than their nonfraud
counterparts While earnings management (e.g., one-time “big bath” restructuring charges,
cookie jar reserves, creative acquisition accounting, excessive charges and write-offs, and
abandoning of unprofitable operations) could produce some of the evidence on conservatism, it is
not thought to be the only explanation In times of economic losses, managers exaggerate the
losses through income-decreasing discretionary accruals for purposes of earnings management
However, according to Givoly and Hayn (2002), it is important to note that this does not support
the timely loss recognition argument because they do not predict any relation to cash flows nor
can they fully explain the systematic versus idiosyncratic understatement of net assets Thus,
there is not always a direct relation between asymmetric timeliness and accounting conservatism
While aggressive accounting choices may reduce the degree of reporting conservatism “they
cannot turn the whole tenor of the financial statements into being non-conservative or even
neutral” (Givoly et al., 2007)
1.2 Litigation Risk
Changes in auditors’ liability exposure in recent decades have been documented by
Kothari et al (1989) who found an increasing degree of conservatism in high litigation periods
They categorized liability exposure based on four liability regimes as evidenced from enactments
Trang 19and events surrounding securities reforms covering the period 1933 through 1985.8 Following Kothari et al (1989), Basu (1997) examined the period 1963-19909 and predicted conservatism measures to increase in periods following liability increases and to remain constant in periods
following court decisions that restricted liability growth For example, Basu (1997) empirically
found a significant increase in conservatism in two high-litigation growth periods and no increase
in low-litigation growth periods, a result consistent with litigation generating different degrees of
conservatism
However, in regards to firm-specific legal liability, the strength of many of these
associations has not been directly established This study aims to fill a void in the literature by
examining the conservative accounting reporting practices of firms that have been specifically
targeted as allegedly committing fraud by the U.S Securities and Exchange Commission (SEC)
as opposed to using only proxies for the litigation period or proxies for auditor litigation Further,
given the proposition that litigation risk has been predicted to cause an increase in accounting
conservatism for U.S firms in general, this is a broad statement, and given that no one firm is
totally immune to litigation risk, it is relevant to refine this concept to specific firms that do
indeed warrant an actual increase in litigation risk Therefore, I examine whether the degree of
accounting conservatism increases surrounding the alleged fraud manipulation date10, when differences in litigation risk are expected to occur Firms with a higher incidence of alleged
fraudulent activity are assumed to be the most vulnerable to the threat of litigation risk Whether
or not firms allegedly accused of committing fraud are more conservative has not been
Trang 20conclusively documented in the extant literature Since research has considered accounting
conservatism to be a corporate governance mechanism (Guay and Verrecchia, 2007), it would
seem paradoxical if alleged fraud firms predispose themselves to higher levels of conservatism
However, based on the theory proposed by Watts (2003a), I argue that the threat of litigation and
exposure to political costs should induce firms to increase their conservative accounting practices
Since the mechanism of conservatism can be viewed as a corrective action to the over-optimistic
behavior of management, if firms use accounting conservatism while they are also manipulating
earnings and engaging in fraudulent activity, accounting conservatism could have the propensity
to mask fraud Recently, Bagnoli and Watts (2005) report that there is a positive correlation
between conservative financial reporting policies and the likelihood of a firm beating earnings
expectations Thus, there is an indication that firms may be “padding” their financial reports in
order to later exceed earnings expectations (Marshall and Heffes, 2005) Levitt (1998) states that
“if these charges are conservatively estimated with a little extra cushioning, [the] conservative
estimate is miraculously reborn as income when estimates change or future earnings fall short.”
This suggests that corporate fraud could be on the rise again Therefore, the main research
question I address is whether or not the degree of accounting conservatism is higher for firms
allegedly accused of fraudulent activity and examine the point in time that this is most likely to
occur
1.3 Regulation and Standard Setting
In regards to the role of regulation and standard setting, Watts (2003a) predicts that
increased liability from regulation provides managers and auditors with incentives to be more
conservative This can be traced back to financial reporting surrounding the U.S Securities Acts
of 1933 and 1934 Litigation under the Securities Acts encourages conservatism because the
Trang 21probability of litigation is higher when earnings and net assets are overstated versus understated
Therefore, managers have an incentive to report conservative values for earnings and net assets as
a means to address moral hazard.11 Agency theory postulates that the responsibility of managers and regulatory commissions is to monitor management incentives and behavior (Jensen and
Meckling, 1976) However, regulation to deter fraud is not a new legislative phenomena
(Rockness and Rockness, 2005) In 1987, the Treadway Commission studied the importance of
fraud-risk factors, termed red-flags, that consisted of incentives to commit fraudulent financial
reporting and opportunities that allowed such frauds to occur (Treadway, 1987)
1.3.1 The Private Securities Litigation Reform Act (PSLRA) of 1995
The Private Securities Litigation Reform Act of 1995 (hereafter, PSLRA) altered the
litigation environment by eliminating joint and several liability where auditors could be named as
defendants in lawsuits due to their “deep pockets,”12 or wealth-at-risk effects, rather than culpability It was also the first requirement for auditors to report fraudulent activity to the SEC
The passage of the PSLRA made it more difficult to file class action lawsuits in federal court
Opponents of the PSLRA indicated that it provided relief to auditors from litigation risk, which
resulted in lowering audit quality and ultimately reducing investor confidence (Geiger et al
2006) Lee and Mande (2003) maintain that the PSLRA decreased audit quality as evidenced by
an increase in income-increasing discretionary accruals after the passage of the Act Francis and
Krishnan (2002) found that Big 4 auditors were less likely to issue a going concern report to their
clients after the passage of the Act, a result consistent with decreased audit quality
Trang 22In terms of accounting conservatism, Chan and Pae (1998) found that the elimination of
joint and several liability of the PSLRA actually caused auditors of firms to adopt even less
conservative accounting practices Extending Basu’s (1997) analysis of asymmetric timeliness
and legal liability, Liu and Thornton (2005) examined the time period surrounding the PSLRA
They convey that asymmetric timeliness declined immediately after the PSLRA and marginally
increased again during the 1997 and 1998 period when litigation shifted to state courts During
1998, conservatism initially declined and increased again when the 1998 Securities Litigation
Uniform Standards Act reversed previous actions and required class action lawsuits to be filed
again in federal courts
1.3.2 The Sarbanes-Oxley Act (SOX) of 2002
In terms of more recent regulation, The Sarbanes-Oxley Act (SOX) of 2002 was enacted
as a direct result of the more well-known and publicized accounting scandals that swept the U.S
in the later 1990s.13 The SOX Act addresses corporate governance and accountability by improving the quality and transparency of financial reports Section 404 of the SOX Act
specifically details detecting weaknesses in internal controls These corporate controls have been
instituted to enforce and control firms from committing fraud Section 302 requires managers to
certify and disclose these material weaknesses (Beneish et al., 2008) Due to the passage of the
SOX Act, information asymmetry should be reduced as firms are required to provide more
transparency in their financial disclosures It is relevant to investigate accounting conservatism in
13
The accounting profession has been plagued by well-known corporate accounting scandals Studies frequently reference Enron, Worldcom, and Arthur Anderson as the most notorious firms involved in these accounting debacles Yet, there are many other firms who have been accused of fraudulent financial activity but are less well-publicized Ironically, it has not only been companies who are allegedly accused
of fraudulent activity, but the leading Big-4,5 public accounting firms such as Arthur Anderson, Deloitte & Touché, Ernst & Young, KPMG, and PriceWaterhouseCoopers, who have been accused of negligence in their duty as auditors and have SEC enforcements issued against them
Trang 23this context because transparency has been defined as exemplifying the characteristics of both
timeliness and conservatism (Ball et al., 2000) and may be considered a desirable earnings
attribute (Francis et al., 2004; Watts, 2003a)
Depending on the characteristics of a regulatory act, the degree of earnings quality or
conservatism does not always stay the same For example, compared to the PSLRA, it has been
suggested that the SOX Act may have different regulatory effects on corporate reporting As
such, it may be causing companies to become more conservative, rather than less conservative, in
their financial reporting The SOX Act is intended to increase the degree of transparency, increase
the risk of litigation, and hence, increase accounting conservatism among firms, with its intention
of decreasing the level of fraud occurrence Therefore, it is relevant to determine whether
changes in the recent wave of accounting debacles are associated with changes stemming from
government regulation and standard setting.14 The effect of changes in the legal environment has the propensity to alter the degree of earnings quality and subsequent potential fraudulent activity
However, many question how much more effective the SOX Act will be in deterring
unethical and fraudulent management behavior The parallels of the former regulatory periods
compared to the current setting raise doubts as to whether this type of behavior can be legislated
(Rockness and Rockness, 1980) Fraud may also be challenging to predict because of the mere
random acts by a few agents (Cloninger and Waller, 2000) Likewise, a corporation’s culture can
determine how people behave when they are not being watched (Tierney, 2002)
It is important to determine the effect of accounting conservatism for firms allegedly
accused of committing fraud as this would lend support as to why the FASB should still continue

According to a 2006 report by the Association of Fraud Examiners, the median fraud loss per scheme for the 2004-2006 period was greater for small organizations than for large organizations (JAcct., 2007) This finding is timely in that the SEC is granting further compliance relief and leniency from Section 404 of the Sarbanes-Oxley Act (SOX) to smaller public companies and many foreign private issuers (SEC, 2006) Small firms have been found to be associated with a greater percentage of loss firms (Klein and Marquardt, 2006)
Trang 24to monitor and show cause for controlling and providing better disclosure on the increasing
effects of conservatism and whether conservatism introduces additional bias into the financial
statements, thus increasing information asymmetry Therefore, the topic of fraud is still very
important and timely as the environment and economic conditions change
1.3.3 Standard Setting
Accounting conservatism may reduce the political costs faced by, not only accounting
regulators, but by standard setters Research dealing with positive accounting theory has
emphasized interest relating to the influence of political costs on accounting procedure choice
(Watts and Zimmerman, 1979) The influence of the political process on accounting
conservatism is one reason that the SEC has banned upward valuations on assets (Watts, 2006)
Yet, more recent standards appear inconsistent with conservatism as they create estimates that are
not verifiable and may possibly be subject to fraud For example, due to the lobbying and
political interests of investment bankers, Statement of Financial Accounting Standard (SFAS) No
142, Goodwill and Other Intangible Assets, adopted in 2001, changes the way firms calculate
impairment charges Prior to this standard, goodwill was amortized over 40 years as an expense
However, amortization of the goodwill asset did not necessarily reflect economic changes in the
value of an investment Under the new provision, companies annually conduct goodwill
impairment tests If goodwill has permanently declined in value, an impairment loss is taken and
written off as an expense (Duangploy et al., 2005)
Goodwill can be generated internally or through a business combination
“Non-amortization of goodwill and related impairment tests should ‘increase representational
faithfulness’ and improve the transparency of accounting” (Massoud and Raiborn, 2003)
However, this discretion could provide a mechanism to manipulate earnings and lower earnings
Trang 25quality in order to meet analysts’ or managements’ expectations Sevin and Schroeder (2005)
report that SFAS No 142 enabled companies to engage in earnings management and small firms
were more likely to employ “big bath” charges Thus, eliminating amortization expense and
using impairment tests raises net income with no corresponding increase in cash flows These
write-offs from impairment can signal a loss in economic value In addition, measuring the
impairment of goodwill when different valuation models are employed could inconsistencies
(Lander and Reinstein, 2005) Statement of Financial Accounting Standards (SFAS) No 144,
Accounting for the Impairment or Disposal of Long-Lived Assets, reflects the demise of the pooling-of-interests method of accounting for business combinations and specific assets or asset
groups It also avoids amortization, replacing it with a two-step impairment test Overall, these
two standards require the estimation of non-verifiable and non-contractible future cash flows
which could lead to manipulation Nonverifiability is inconsistent with the original concept of
accounting conservatism and does not lead to more transparency in the financial statements
(Watts, 2003a), but to more manipulation (Sevin and Schroeder, 2005) and the potential for
increased litigation risk
In summary, based on the prior discussion of the role of regulations and standards, in
regards to the Private Securities and Litigation Reform Act of 1995, there is empirical evidence to
suggest that as litigiousness decreases, conservatism may decrease and this relation has the ability
to increase fraud Given that proof of fraud requires the verifiability of accounting numbers,
conservatism should in theory be associated with a decrease in fraud (Watts, 2003b) However,
since the SOX Act has been predicted to be associated with a shift in the information environment
representing more litigiousness, the amount of conservatism is predicted to increase The
standard relating to SFAS No 142, Goodwill and Other Intangible Assets is expected to produce
the opposite results contrary to the SOX Act
Trang 261.4 Cost of Capital
Cost of capital is one of the most important benchmarks to evaluate the ability of firms to
invest their funds and to evaluate the quality of their existing investments (Habib, 2006) A
firm’s cost of capital is of interest to regulators, investors, accountants, academicians, and
management for capital budgeting decisions, equity valuation, capital structure, and firm
profitability (Easley and O’Hara, 2004) Arthur Levitt, former Chairman of the Securities and
Exchange Commission, has suggested that “high quality accounting standards…improve liquidity
[and] reduce capital costs” (Levitt, 1998) An increased level of disclosure reduces the possibility
of information asymmetries (Guay and Verrecchia, 2007) and should lead to a lower cost of
capital effect Barth et al (2005) found that firms with more transparent financial statements
benefited from a lower cost of equity capital Financial reporting of low quality earnings
increases the risk of inefficient resource allocation and could increase the cost of capital The
incidence of earnings manipulation by firms adversely affects the financial reports, especially the
information content of earnings (Wilson, 2008)
Since the cost of equity capital serves as a summary measure of investors’ resource
allocations, a decrease in information asymmetry should reduce the cost of capital through
reduced transaction costs and/or a reduction in uncertainty or estimation risk (Botosan, 1997,
Botosan, 2004) Francis et al (2004) document that information asymmetry can be caused by
poor earnings quality and poor earnings quality is positively related to an increase in a firm’s cost
of capital A reduction in information asymmetry through improved accounting disclosures, such
as conservatism, may reduce a firm’s information risk and reduce the cost of equity capital
Based on this relationship, Francis et al (2004) suggest a negative association between
conservatism and cost of capital They state that “high quality earnings, by reducing the
Trang 27uncertainty in earnings as an informative signal about the pay-off structure, reduce the cost of
capital.”
Cloninger and Waller (2000) state that based on the hedging hypothesis, firms engage in
fraud as a means of enhancing returns or smoothing cash flows, thereby reducing variability.15 The lower variability in firms’ cash flows should translate into a lower market beta Higher post
event betas vis-à-vis pre-event betas could signal that a firm’s market risk has increased as a
result of the disclosure of the fraudulent activity However, lower post event betas could serve as
evidence that the market anticipates lower risk associated with the cessation of the firm’s illegal
activities According to the speculative hypothesis, this serves as evidence that the market
perceives this fraudulent activity as speculative The disclosure and anticipated cessation of the
fraudulent activity could cause a firm’s beta to fall Following this theory, a motivation for firms
to commit fraud could be due to the desire to attract external financing at a lower cost This
motivation has received little attention in the academic literature (Dechow et al., 1996) I
examine the impact of the disclosure of accounting conservatism on alleged fraud firms and its
temporal effect on the ex ante cost of equity capital
1.5 Purpose
Based on the previous discussion, the purpose of this study is to empirically determine
whether the degree of asymmetric timeliness and firm-specific accounting conservatism is higher
surrounding the pre- and post- fraud manipulation date, (t-3 to t+3), for firms accused of alleged
fraudulent activity compared to a control sample I extend the litigation explanation proposed by
Watts (2003a) to take into account firms targeted by the SEC’s Enforcement Division The
15
Using a sample of 129 fraudulent disclosures, Cloninger and Waller (2000) found that 42 of the disclosures had betas that significantly increased, 22 disclosures whose betas did not change significantly, and 65 disclosures whose betas decreased significantly after fraud was discovered
Trang 28means by which firms who are accused of alleged fraud are scrutinized is through the
announcement and issuance of the SEC’s Accounting and Auditing Enforcement Releases
(AAERs), Litigation Releases, Administrative Releases, and other listings available on the SEC website.16 I examine the period of regulation surrounding the SOX Act of 2002 to determine whether the nature of the Act has caused accounting conservatism to differ between these firms I
examine whether alleged fraud firms that have applied SFAS No 142, Goodwill and Other
Intangible Assets, in their financial statements vis-à-vis a matched control group are associated with more accounting conservatism I also empirically test whether firms allegedly accused of
fraudulent activity are associated with a higher ex ante cost of equity capital Additionally, I
examine if the contagion effect of asymmetric timeliness of earnings is similar, relative to all
firms in the same industry
This study is relevant in that there continues to be a growing market concern over the
increasing complexity of financial reporting The concept of conservatism affects all of the
underlying assumptions in the financial statements (Krishnan, 2005) If accounting earnings are
non-verifiable, the quality of other information is also suspect Ball et al (2000) and Watts
(2003b) state that a feature of accounting conservatism is that it facilitates the effective
monitoring of managers and contracts The accounting profession is helping to lead the charge in
the war on financial disclosure and transparency, as well as the SEC As the SEC’s chairman
Christopher Cox stated, “if the rules become a thicket in which fraudsters can hide instead of a
means to achieve the truth, then we can’t achieve our goals of protecting investors” (JAcct.,
2007) Thus, if accounting conservatism is higher for firms that have been allegedly accused of
fraud, then this calls into question the role of conservatism as a corporate governance mechanism
16
Available at http://www.sec.gov Prior research has identified fraudulent firms by using SEC
enforcements, news releases available on the Lexis Nexis Academic Database (Caskey and Hanlon, 2005),
the Wall Street Journal lndex (Marciukaityte et al., 2006), and publications by the SEC (1989) (Dechow et al., 1996)
Trang 29The implications of this study should also be of interest to financial analysts Givoly and
Hayn (2002, 2000) and Kwon et al (2006) suggest that an analysis of the financial statements is
meaningless unless there is an adjustment for the effect of varying degrees of conservatism before
comparisons can be made between firms Research indicates that financial analysts are beginning
to make this adjustment when comparing the financial statements of firms when using
cross-country comparisons (French and Poterba, 1991) Adjustments for conservative accounting are
also being incorporated into previous accruals models to attenuate any bias or model
misspecifications (Ball and Shivakumar, 2006)
1.6 Motivation for Study
The extent of fraud also has implications for legislators, regulators, auditors, and
academicians still trying to understand the motivations, root causes, and consequences of fraud
Many enforcement actions involve settlement offers where companies pay off their poor
discretions Many of these companies may have the necessary funds to settle their transgressions
In fact, most recently, BusinessWeek published its 2007 top 50 best performers ranking list
(Foust, 2007) Included on this list are ten companies included in the initial sample that have had
SEC’s AAERs issued against them Therefore, the consequences for firms that have been
accused of fraudulent activity have the propensity to vary
Very few studies have moved beyond the general area of accruals as a metric in
determining the association with fraud In addition, evidence suggests that investors do not fully
see through earnings management as reflected in abnormal accruals While prior studies have
found a positive association between earnings management and those firms that commit fraud,
there are limitations based on using only accruals (Daske et al., 2006; Dechow et al., 2003;
Dechow and Dichev, 2002; Durtschi and Easton, 2005; McNichols, 2002) While some firms that
Trang 30have managed earnings upwards have shown subsequent stock price declines, other firms that
have managed earnings downwards have had positive subsequent returns (Healy and Wahlen,
1999) This raises the question as to whether or not abnormal accruals can explain the variation
in earnings momentum In addition, this study also has implications for the theory surrounding
accounting conservatism and the types of firms that exhibit higher levels of accounting
conservatism I am not aware of any study which has examined accounting conservatism in an
adverse selection setting with its relation to alleged fraud firms
Prior research has often used firms that have been involved in litigation as suggesting that
they are a proxy for poor earnings quality (Khurana and Raman, 2004, Caskey and Hanlon,
2005) Thus, it has only been inferred that an SEC’s AAER release or a restatement implies that
a firm has poor earnings quality However, this may not always be the case For example, the
incentive to commit fraud may occur to increase managerial executive compensation packages
This would support the notion that earnings are manipulated, not because of poor financial
condition, but because of greed It could be more than just the need to inflate earnings that drives
fraud It has not been formally tested in the literature whether firms that have been issued SEC
Enforcement Releases really possess a lower earnings quality or if they are seeking an abnormal
earnings level One of the caveats lacking in the literature is specifically measuring the earnings
quality of these firms using several alternative metrics Francis et al (2004) suggest that the
benefits of using different earnings attributes are specific to the setting considered due to the
ability of the attributes to capture distinct constructs
Prior research has found that the SEC Enforcement Releases elicit a strong negative
market reaction and the initial disclosure of alleged corporate activities results in significant
negative abnormal returns to shareholders (Cloninger and Waller, 2000; Feroz et al., 1991;
Trang 31Karpoff and Lott, 1993).17 This often leads to downward revisions in the expected future earnings
of these firms (Dechow et al 1996) Firm value is anticipated to decrease because the expected
stream of cash flows may be lower What is not evident is how much, if any, of the downward
price revision is attributable to an increase in the cost of capital discount rate that investors assign
to future cash flows By determining this cost of equity capital rate, this allows us to discern
whether or not the perceived risk of going forward and recovering from the alleged fraud is
affected by the announcement
If cost of equity capital is increasing at the same time that earnings management is
increasing for these firms, then it remains an empirical question as to whether accounting
conservatism is a good measure to gauge performance along with its relation to the cost of equity
capital This also justifies the need to empirically test the use of different settings by using
alternate measures of accounting conservatism According to Givoly et al (2007), the use of the
Basu (1997) differential timeliness (DT) measure in different research venues needs to be more
selective and qualified because the use of the (DT) measure can lead to anomalous results and
differs across research settings The Basu (1997) differential timeliness component is based on a
sample aggregate attribute and often is not calibrated as a firm-specific measure of conservatism
Givoly et al (2007) also find that asymmetric timeliness is not lower for firms in some situations
where one would expect less conservatism For example, they contend that asymmetric
timeliness is higher for firms that restated their financial statements and issued capital However,
considering the effect that litigation risk has on accounting conservatism, this direction appears
Trang 321.7 Research Contribution
This study contributes to the literature by filling a void in what Watts (2003b) has
proposed that finer tests of variations in accounting conservatism during contracting and
expanding regulatory and litigation periods need to be performed in order to determine whether
standard setting generates conservative financial reporting Further, while Watts (2003a) offers
litigation risk as one of the explanations for the increase in accounting conservatism, this
empirical relation has not been formally tested Therefore, I empirically determine whether
litigation and regulation and standard setting encourage conservatism By focusing on these
areas, I aim to fill a void in the literature by also drawing upon Basu (1997) and Kothari et al
(1989) who showed an increasing degree of conservatism in high litigation periods
This study contributes to the literature by determining whether alleged fraudulent activity
is associated with higher levels of accounting conservatism, regulations and standards, and
increases or decreases in cost of equity capital compared to a non-fraud control sample I
examine if accounting conservatism and the cost of equity capital increases surrounding the
relative alleged fraud manipulation date Although there have been numerous studies measuring
the cost of capital of firms in general, and the construction of several alternate specification
models, I am not aware of any study that has examined the association of alleged fraud firms and
their implicit cost of equity capital calculations
I contribute to the literature by examining the period surrounding the Sarbanes-Oxley Act
(SOX) of 2002 Companies have been subject to litigation proceedings long before the SOX Act
became effective Some opponents of the SOX Act argue that the costs of compliance are too
harsh Some even attribute the exodus of publicly-traded firms to the private sector as a result of
too many restrictions imposed by the Act (Morgenstern et al., 2004) The effects of SOX could
cause an increase or decrease in the incidence of fraudulent activity In accordance with Watts
Trang 33(2003a), I predict that if litigation risk increases, then asymmetric timeliness or accounting
conservatism should increase However, if firms are not being prosecuted but issued injunctions
in exchange for settlements which decrease litigation risk, than the Act has the effect of
decreasing conservatism Likewise I contend that there should be a negative relation between
accounting conservatism and the cost of equity capital because conservatism acts as a disclosure
mechanism
If differences in accounting conservatism and cost of equity capital are not significant
between the fraud and the non-fraud control samples, then this could imply that the government
may have overreacted with the SOX regulations It has been suggested that the government may
have reacted precipitously to the recent scandals, motivated by a political agenda and “based on
anecdotes” without considering the consequences when drafting the Act (DeFond and Francis,
2005)
Finally, I determine whether or not fraud that occurs in one industry will have contagion
effects relative to firms in similar industries in terms of asymmetric timeliness of earnings.18 Prior studies have indicated that the computer equipment sector (Dechow et al., 1996), the
business services sector (Erickson et al., 2006), and other manufacturing sector (Caskey and
Hanlon, 2005) have been characterized as having some of the highest levels of alleged fraudulent
activity Erickson et al (2006), in examining equity incentives, indicate that the business service
sector has had the most fraudulent activity It has also been suggested that firms that are
implicated in fraudulent scandals tend to have widespread industry effects that could affect the
level of asymmetric timeliness within those same industries Using Fama and French (1997) 48
industry classifications to measure these firms, I examine whether the distribution of alleged
fraud firms has changed and whether or not there are contagion effects that significantly comprise
18
Sidak (2003) suggest that “WorldCom’s fraudulent statements may have raised competitors’ costs by inducing inefficient investment in capacity and inefficient expenditures for customer acquisition.”
Trang 34the sample I am aware of no other study that has examined asymmetric timeliness as a measure
of accounting conservatism for firms in the same industry that have been affected by alleged
fraudulent activity Fraud often occurs because the culture has become infected (Sweeney, 2003)
Basu (2001) states that accounting methods tend to cluster both in time and in particular
industries Balsam et al (2003) find that clients of industry specialist auditors have lower
discretionary accruals and higher ERCs than clients of nonspecialist auditors Their finding
suggests that clients with industry specialists have higher earnings quality than clients of
nonspecialist auditors Kwon et al (2006) suggests that to control for mandated GAAP versus
voluntary conservatism, additional analysis can be conducted at the industry level
1.8 Research Expectations and Methodology
The discussion in this section revolves around the research expectations of the study and
an introduction to the research methodology I begin by examining the main research question of
whether the degree of accounting conservatism increases or decreases surrounding the alleged
fraud manipulation date Following Dechow et al (1996), I examine the t-3 through t+3 period
surrounding the alleged fraud manipulation date in the financial statements, t=0 I draw upon
prior literature that states that higher quality earnings are those earnings that have less evidence of
earnings management and are desirable because they reduce information asymmetry and result in
a capital market advantage (Francis et al 2004) I expect there to be an increase in accounting
conservatism as a response to the anticipation and consequence of fraud and that the magnitude of
conservatism will be higher for the alleged fraud group than for the matched control group
surrounding the relative alleged fraud manipulation date in the financial statements Based on the
theory of litigation and conservatism provided by Watts (2003b) and LaFond and Watts (2008), I
expect the level of accounting conservatism should increase in the period initially preceding and
Trang 35initially following the relative date of alleged fraud manipulation It is during this period that the
risk of litigation would be highest for a firm allegedly accused of fraudulent activity
Given the prior research on the theory of disclosure levels, it is also possible that the
announcement of fraud, having removed future uncertainty about the firm’s earnings, might
actually reduce future risk (Khan and Watts, 2007) A decrease in litigation risk may cause
conservatism to decrease For example, a firm may have used fraudulent activity to enhance
bonuses, to facilitate the firm over a certain threshold, or to meet a short-term analyst forecast
However, based on the prior discussion, if the risk of litigation increases, accounting
conservatism is predicted to increase
To test the main hypothesis, I begin by using the seminal Basu (1997) model of aggregate
asymmetric timeliness However, the power and reliability of the Basu (1997) timeliness
measure to gauge reporting conservatism may react differently depending on the setting examined
(Givoly, 2002; Ball and Shivakumar, 2006) The results can be contingent on the sample size
attributes, the reliability of the measurement data, and the means used to identify firms targeted as
having allegedly committed fraud Research has indicated that accounting conservatism is
considered to be downwardly biased using the Basu (1997) model because the validity of using a
reverse regression model of earnings regressed on returns may render the results non-interpretable
and subject to measurement errors (Dietrich et al., 2006) Therefore, I also apply alternate
measures of firm-specific accounting conservatism in cross-sectional analysis Using actual and
simulated data, Givoly and Hayn (2002) find that certain characteristics of the information
environment, unrelated to accounting conservatism, affect the sensitivity of the differential
timeliness measure This justifies the need to empirically test the advantages of using different
settings in application of the Basu (1997) differential timeliness measure as well as to compare
and contrast them with alternate measures of accounting conservatism
Trang 36Next, I examine whether government regulation and standard setting affects firms’
reporting practices Based on the prior discussion regarding the Private Securities Litigation
Reform Act of 1995, the Act was found to decrease conservatism and increase fraudulent
reporting Conversely, the Sarbanes-Oxley Act has been anticipated to increase accounting
conservatism and decrease fraudulent reporting I begin by using the Basu (1997) model and
extend it to take into consideration the SOX regulation period and the extent to which firms have
applied SFAS No 142, Goodwill and Other Intangible Assets The extent to which other
firm-specific accounting measures of accounting conservatism are associated with alleged fraud firms
after the SOX Act became effective are also examined
Furthermore, I examine whether attracting external financing at a lower cost is a
significant motivation for the alleged manipulation that results in SEC enforcement actions A
decrease in accounting conservatism may result in an increase in information asymmetry Based
on prior research, an increase in information asymmetry is associated with an increase in cost of
equity capital Based on this line of reasoning, there should be a negative relation between
conservatism and the cost of capital The level of conservatism used by firms should map into the
effect of the cost of equity capital In terms of potential fraudulent activity, a distinct
disadvantage of earlier research dealing with changes in cost of equity capital estimates is that the
measures were not directly specified, yet only inferred For example, Palmrose et al (2004) did
not find any increase in the bid-ask spread, a proxy for cost of capital surrounding a restatement
announcement Dechow et al (1996) only indirectly examined whether the cost of capital
increased for a select group of SEC-identified firms by examining stock price, bid-ask spreads,
and the number of analysts following the firm While many models have used forecasts based on
analysts’ projections, Easton (2006) states that “there is the potential of bias in estimates of the
expected rate of return due to biases in analysts’ forecasts of earnings.” More optimistic forecasts
Trang 37will increase forecast error and bias the expected rate of return, upward leading to the conclusion
of a higher cost of equity capital Less optimistic forecasts will bias the expected rate of return
downward leading to the conclusion of a lower cost of capital Forecast models tend to differ due
to the number of periods used to forecast expected earnings Due to these limitations, alternate
measures of the cost of equity capital will be incorporated
Finally, I examine whether or not fraud that occurs in one industry will have contagion
effects relative to firms in other similar industries in terms of asymmetric timeliness of earnings
as a measure of accounting conservatism It has been suggested that firms that are implicated in
fraudulent scandals tend to have widespread industry effects that could affect the level of
accounting conservatism and cost of equity capital within those same industries Gleason et al
(2008) found that firms that restated their financial statements caused decreases in share prices
among peer, non-restating firms in similar industries I construct this analysis by examining the
industries that comprise the highest total proportion of the sample
1.9 Sample Selection
I begin by identifying firms targeted by the SEC with the highest probability of allegedly
committing fraud vis-à-vis a control sample of firms An advantage of using the SEC’s
Enforcement Releases is that the announcements consist of firms that the SEC has targeted as
possessing a higher probability of being successfully found guilty of committing fraud (Feroz et
al., 1991; Dechow et al., 1996; Erickson et al., 2006) It is important to note that
contemporaneous research that investigates restatements differs from accusations of accounting
fraud even though the accounting treatment effect may remain the same Palmrose and Shultz
Trang 38(2002) found that of 492 restatements examined,19 only 11 percent resulted in an SEC AAER release
The sample used in this study differs from restatements in terms of the intent (scienter) to
deceive and the magnitude of the deception While earnings management, restatements, and
fraud share certain attributes, there are distinctions between them (Erickson et al 2006) Thus,
restatements may involve genuine disagreements regarding GAAP, unlike fraud which involves
intentional applications of misconduct both within and outside the realms of GAAP (Dechow et
al., 1996) A limitation of studying restatements is that they may not capture that intent A higher
threshold test is to study firms allegedly accused of fraudulent activity as this increases the power
of the tests
It is important to note that the SEC’s prosecution practices have themselves been
considered conservative in nature (Bhattacharya, 2006; Caskey and Hanlon, 2005), at least prior
to the SOX Act For example, the penalties inflicted on firms have varied as they often consist of
cease and desist orders, restatements, settlements, injunctions, and civil or criminal prosecution.20 Feroz et al (1991) state that “targets’ managers settle enforcement actions by consenting to an
injunction that prohibits future violations of the securities laws.” A reason stated for the lack of
prosecution of firms allegedly accused of fraud is due to the interpretation that investors have
already been victimized by the market decline associated with the announcement Any additional
fines to the company would only hurt the shareholders, yet again
19
For the period 2002-2005, restatements were initiated internally by company management or internal auditors (58%) and other agencies and external auditors (24%) This is an increase from the 1997-2002 period for restatements prompted by company management or internal auditors (49%) and other agencies and external auditors (16%) (GAO, 2002; 2006)
20
Most recently, options backdating, thought to be the next big corporate scandal, has lost its momentum Many of the original prosecutors on the task force have resigned Legal experts are contemplating how well the backdating issue will fare in court This is due to the fact that many of the prior accounting scandals have failed to produce the expected criminal jail sentences The intent of options backdating in the pre-SOX period were widespread and provided little guidance Thus, it has been interpreted that “not everyone convicted in the court of public opinion suffers the same fate in front of a jury” (Burrows, 2007)

Trang 40CHAPTER 2 LITERATURE REVIEW
2.1 Background and Purpose
The purpose of this chapter is to provide a review of the relevant literature regarding
accounting conservatism, fraudulent financial reporting, and cost of equity capital First, I begin
with a discussion of earnings quality given that it remains an empirical issue as to whether
accounting conservatism can be considered an earnings quality attribute Next, I define
accounting conservatism, report the findings and major research contributions, and discuss the
relevance of the research designs utilized in the extant literature Thereafter, I discuss studies on
fraud, limitations of prior research methods and extensions, and a review of the cost of equity
capital
2.2 Definition and Relevance of Earnings Quality
Investors use financial statements in order to forecast firms’ future profitability and for
valuation purposes The goal of accounting information is to reduce information asymmetry or
risk between firms and the stock market Research has attempted to show that, not only is the
quantity of disclosure of financial information important, but also the quality of the financial
information (Francis et al 2004; Schipper and Vincent, 2003; Penman, 2003)
“Earnings quality is an important aspect of evaluating an entity’s financial health Yet
investors, creditors, and other financial statement users often overlook it.” (Bellovary, 2005)
Schipper and Vincent (2003) define earnings quality as “the extent to which reported earnings
