Abstract:
We explore the content and determinants of Securities and Exchange Commission (SEC) comment letters and then examine whether letter resolution affects both the firm’s information environment and that of its peers. Our content analysis confirms that the comment emphasis is disclosure. If the resolution of an enquiry improves disclosure thereby enhancing the preannouncement information environment, we would expect dampened market reactions around ensuing earnings announcements. Our results support the hypothesis showing reduced return volatility and trading volume after the comment letter for targeted firms, and where SEC scrutiny is intense, reduced return reactions for industry peers. This spillover effect is consistent with our determinants model, which shows that the probability of receiving a letter is higher for industry leaders suggesting that peers mimic industry leaders. We conclude the SEC’s oversight has both direct and indirect effects.

1. Introduction
In this paper we investigate whether regulatory oversight of financial reporting affects
companies’ information environment. We address the question by examining the content,
determinants, and ensuing market consequences of the Securities and Exchange Commission’s
(SEC) comment letters. The SEC reviews a significant portion of the filings (10Qs, 10Ks, S1-4
etc.) submitted to them. If the SEC staff identify potential deficiencies, they send a comment
letter to the company seeking clarification, more information, or revision of the filing or future
filings. Unless the company voluntarily discloses it, the SEC enquiry is unknown to the public
during its existence. In 2005, the SEC began to publicly release comment letters of resolved
cases. 1 These letters provide a unique opportunity to investigate the monitoring role of the SEC
in the U.S. capital market.
The stated goal of the SEC review process is to improve the quality of material disclosure
to investors in a timely manner. However, whether the review process has any effect on the
information environment is unclear. On the one hand, disclosure may improve as a result of the
review, thereby providing useful information to investors and enhancing a firm’s information
environment. For example, an expanded or clarified revenue recognition policy disclosure could
improve user forecasts of earnings, resulting in less surprise at future earnings announcements.
Alternatively, any additional disclosure may be an oversupply of information and thus have little
economic consequence. This alternative seems highly plausible, given that under current
accounting and disclosure standards, the U.S. information environment is already rich.
1 Section 2 describes additional institutional details on comment letters.
2
Moreover, we might expect cross-sectional variation in any potential effects. Some letters might
address more issues or issues of greater severity and thus create a larger improvement.
Alternatively, effects may vary across firm size. Smaller firms may not have the same quality of
information environment, so the impact of the SEC’s comments may be greater. Finally, the
changes in disclosure that arise from comment letters could be mimicked by industry peers,
hence we explore industry spillover effects. We expect any such effects to be most pronounced
where SEC scrutiny is intense within an industry.
We collect the comment letters from the SEC’s website for 2003-2006 and retain those
related to 10Ks and 10Qs. We conduct content analysis on a subsample and document that the
vast majority of letter comments address disclosure issues. We then explore the attributes of
letter recipients. Whether or not a firm receives a comment letter depends on two factors: the
type of firms that the SEC targets for review in that year, and the firm’s reporting quality. The
SEC's review selection criteria are unknown. However, the Sarbanes-Oxley Act of 2002 (SOX)
outlines several factors for the SEC to use when it selects firms for review. We use those criteria
and other factors related to financial reporting quality and find that firms more likely to receive a
SEC comment letter are industry leaders, those that have been public longer and those that have
previously restated their financial results. Greater cash flow volatility and higher Earnings/Price
ratios also increase the likelihood of receiving a letter.
To evaluate the impact of the comment letters on the firms’ information environment we
study the changes in market behavior around earnings announcements. Prior research shows how
information asymmetry and differential information processing by investors affect price and
volume reactions to public announcements (Diamond and Verrecchia, 1991; Kim and
3
Verrecchia, 1991a, b, 1994, 1997; Harris and Raviv, 1993; Kandel and Pearson, 1995). In
particular, a decline in price reactions around earnings announcements suggests that the quality
of the information environment prior to the announcement has improved. Lower volume
reactions indicate less investor disagreement regarding the information content of the earnings
announcement and higher consensus of firm value.2
We find that abnormal return volatility and trading volume around earnings
announcements decline subsequent to the SEC comment letters, and that the magnitude of the
change is economically significant. The return volatility change appears to be concentrated in
small firms and the volume results apply to letter cases which are severe. Our findings are robust
to various approaches that address potential letter selection biases.
In our test of industry spillover effect, we do not find any change in return volatility for
industry peers, on average. However, in industries that receive greater attention from the SEC,
peer firms do show a reduction in price reactions. The magnitude of this reduction is as large as
the comment letter firms. We find no change in volume reactions for peer firms.
Our study is related to four streams of research. The first investigates the economic
consequences of companies that voluntarily commit to higher levels of disclosure (e.g., Welker,
1995; Leuz and Verrecchia, 2000; Brown et al., 2004). These studies provide evidence that the
quality or quantity of disclosure has positive effects. Increases in disclosure levels tend to
generate greater stock liquidity and reduce a firm’s cost of capital and information asymmetry.
2 The above argument is similar to Bailey et al. (2003) and Bailey et al. (2006). Some might conjecture that the reverse of the story is the case, that a higher quality disclosure is associated with a stronger market reaction. This argument is true if earnings quality improves, leading to a stronger ERC. In Section 2 we examine a subsample of 157 comment letters and find that the majority of the comments are related to disclosure, not earnings quality. Therefore, on average, we expect dampened market reactions after the letters.
4
Our paper complements these studies by examining the market consequences of disclosure
changes that arise from the regulator’s direct monitoring of corporate reporting.
The second research path studies the market consequences when the SEC issues a new
regulation, for example, Regulation Fair Disclosure (FD) (Bailey et al., 2003; Heflin et al.,
2003). This research finds that the quantity of voluntary disclosure increases after the adoption of
the regulation, but provides mixed evidence on market related aspects, such as volatility around
earnings announcements and the degree of information asymmetry. Our study explores the
impact of monitoring and enforcement of regulations rather than of issuing regulations.
A third research area which explores private and public enforcement of securities laws
concludes that public enforcement of securities laws has limited value (La Porta et al., 2006;
Djankov et al., 2008a). Jackson and Roe (2009) however, find that these papers underestimate
the extent to which public enforcement is associated with capital market development. Leuz and
Hail (2006) find that firms from countries with more extensive disclosure requirements, stronger
securities regulation, and stricter enforcement mechanisms have a significantly lower cost of
capital. Leuz and Hail base their enforcement construct on a survey of lawyers. In contrast, we
examine a sample of actual enforcement activities undertaken in the U.S. by the SEC. Unlike
LaPorta et al. (2006) and Djankov et al. (2008a) but similar to Jackson and Roe (2009), our
results suggest that there are positive benefits of public enforcement.
The fourth research stream explores the SEC Accounting and Auditing Enforcement
Releases (AAER) (see for example, Feroz et al., 1991; Dechow et al., 1996; Beatty et al., 1998;
Beneish, 1999; Farber, 2005). This research examines the impact of these enforcement actions on
corporate governance, managers, auditors, underwriters, and market participants. Comment
5
letters can lead to AAERs but AAERs are rare. By studying comment letters, we add another
dimension to the research that assesses the impact of the SEC on the U.S. markets.
A working paper by Ertimur and Nondorf (2006) examines a sample of comment letters
for 95 firms that undergo the Initial Public Offering (IPO) process.3 They find no association
between the SEC comment letters and IPO underpricing, bid-ask spreads, or market depth. Our
study differs from theirs along several important dimensions. First, they focus on IPO firms
whereas we study public companies which allows us to examine the change in information
environment after the comment letters. Second, they categorize the content of the letters into
several groups and that grouping may not be representative of the relative importance of various
comments. We use a more objective measure, time to resolution, to proxy for the severity of the
letter content. Finally, while they fail to find any association between comment letter attributes
and the firm’s information environment, we find evidence that targeted firms and, in some
circumstances, their industry peers experience an improvement in their information environment
subsequent to the SEC comment letters.
Our study offers early evidence on the content, determinants and consequences of SEC
comment letters and adds to the literature on the positive effect of quality accounting and
disclosure on the information environment of U.S. firms. We document the beneficial effect of
the oversight role played by the SEC in enhancing and maintaining the quality of the information
environment of firms listed in the U.S. markets. This oversight evidence is important, because
practitioners and academics often focus on the SEC’s role in terms of creating regulations. Our

findings suggest that the SEC’s review process is also an important factor that contributes to the
quality of the U.S. markets. The results could be of interest to policymakers and the Commission
itself, particularly in terms of demonstrating the value of their review efforts. Moreover, the
results could have implications for other countries who wish to replicate the success of U.S.
markets. Finally, this paper is of relevance to the financial statement analysis literature, in that it
demonstrates the potential value of reviewing financial reports.
The paper is organized as follows. Section 2 provides institutional details about the
SEC’s comment letter process and the results of our letter content analysis. We develop our
hypotheses in Section 3 and in Section 4 we outline our research design. Section 5 details the
data and explores the determinants of receiving a letter. Section 6 presents the empirical analyses
and Section 7 concludes.
2. SEC comment letters: institutional background and content analysis
The Securities Exchange Act of 1934 requires public companies to file quarterly (10Q)
and annual reports (10K) with the SEC. The Sarbanes-Oxley Act of 2002 (SOX) requires the
SEC review a company’s filings at least once every three years. Prior to SOX, the SEC reviewed
approximately 20% of the filings each year. The SEC motivates the review program as follows:4
“The full disclosure system for public companies is the foundation of the federal securities laws. Currently, the Division of Corporation Finance achieves the goal
of improving the quality and timeliness of material disclosure to investors by selectively reviewing the periodic financial and other disclosures made by public companies.” (emphasis added)
4 Taken from sec.gov, 2008.
7
Various stated review objectives include identifying potential or actual material accounting,
auditing, financial reporting or disclosure deficiencies; influencing accounting standards and
practices; proposing new and amended disclosure rules; and offering guidance and counseling,
either informally or through no action letters.5 Feroz et al. (1991) cite an SEC official who
claimed that half of all SEC enforcement leads came from reviews of financial statements and
securities filings.
The SEC does not disclose when a firm will be subject to review, so only if a firm
receives a comment letter does it become aware of the review. Many reviews are completed
without issuing any comments. Section 408 (b) of SOX requires the Commission to consider the
following factors in scheduling reviews:
(1) issuers that issued a material restatement of financial results; (2) issuers that
experience significant volatility in their share price as compared to other issuers;
(3) issuers with the largest market capitalization; (4) emerging companies with
disparities in price to earnings ratios; (5) issuers whose operations significantly
affect any material sector of the economy; and (6) any other factors that the
Commission may consider relevant.
When comments are issued, the company receives a letter from the SEC and has ten
business days to respond. The company can either submit a response letter or amend the filing
under review. Follow-up comment letters and responses can be made until the issues are resolved
to the Commission’s satisfaction, at which point the SEC staff advises the filer that the review is
complete.
5 In a speech on July 19, 2000, the SEC Chief Accountant, Robert A Bayless made the following remark, “the review and comment process in the Division of Corporation Finance unearths a surprising number of accounting errors, disclosure deficiencies, and tortured interpretations of GAAP in filings with the Commission.”
8
Prior to 2005, public access to comment letters and the related responses were only
available through a Freedom of Information Act request. Due to an increasing number of such
requests, in 2005 the SEC began to publicly release, on their website, comment letters relating to
filings made after August 1, 2004 but no earlier than 45 days after the review is completed.
Therefore, in the absence of a company’s voluntary disclosure regarding the letter, the public can
learn about the existence and content of the letter only when the SEC releases it. Of course by
then, all the relevant issues have been resolved and interim filings have been enhanced.6
We provide two complete letters as examples, one for the Landec Corporation (Appendix
1) and a second one for Charles Schwab Corp. (Appendix 2). In addition, to provide some
context for the nature and frequency of comments in the letters, we read and manually code the
first batch of the letters posted to the SEC website. The first batch contains 157 letters from
2004-2005. We apply extracts of the Ertimur and Nondorf (2006) taxonomy, since we find that
they accurately represent the nature of comments found in the letters. We present the 80 possible
comment types and a description of each in Appendix 3.
The comments fall into four groups. The first group, Accounting Issues, address big-
picture problems. Comments relate to issues such as adherence to GAAP, materiality, and
auditor issues. The second group, Accounting/Financial Reporting/Disclosure Topics, comprise
comments specific to accounting balances or transactions such as revenue recognition, inventory,
6 Proprietary costs are a major counter force to the incentive to disclose. For sensitive information, companies can request confidential treatment under Rule 83 (17 CFR 200.83). If the request is granted, companies can exclude the confidential information from publicly available filings, and only provide the information to the SEC.
9
related party transactions, and capital expenditures. The third group, Business Issues, address
more generic business issues, such as liquidity, competitive environment, and risk factors. The
fourth group, Tone and Level of Disclosure Issues, is editorial in nature, the comments address
presentation and requests are to emphasize or de-emphasize, clarify or disaggregate, certain
items.
The 157 letters contain 1,504 comments, slightly less than ten per letter, on average.
Forty-five percent of the comments fall into the second group. Within the second group,
questions about revenue recognition are the most frequent, followed by claims, commitments and
contingencies, and then expenses. The other three groups are approximately equal in terms of the
percentage of comments. In the first group, the most common comment is a request for a cite
from authoritative literature to support an accounting treatment. Other frequent comments
include a request to clarify an accounting policy, reasons to explain why the company is not
following GAAP, and a request to disclose certain material information. In the third group, both
MD&A disclosure and liquidity issues receive substantial attention. In the editorial category, the
most common comment is a request for something to be clarified. The second most common
request is to quantify an amount related to a disclosure.
The descriptions of the 80 comment items in Appendix 3 indicate that most of the issues
deal with disclosure. It seems unlikely that earnings or accounting balances would be altered
frequently as a result of the review process. However, there is one exception, item 11 in the first
group, "Not Following GAAP" (see Appendix 3). If this SEC claim is supported, then earnings
may change. To provide further evidence on the nature of the comments, we code the second
group comments into disclosure-related or change in accounting numbers. If the comment
10
suggests that the filer provide more information in the 10K or 10Q, we code it as a disclosure
issue. If the comment is more likely to require a change in a financial statement figure, then we
treat it as an accounting issue. We find ninety-six percent of the comments are disclosure related.
This preliminary analysis suggests that the SEC review process is more likely to impact
disclosure, rather than to revise accounting figures.
3. Hypothesis Development
A large body of research has established a positive relation between enhanced disclosure
and firms’ information environment. For example, Welker (1995) shows that a well-regarded
disclosure policy reduces information asymmetry and increases liquidity in equity markets.
Healy, Hutton, and Palepu (1999) find that when firms expand their voluntary disclosure, they
can attract more analyst following and improve stock liquidity. Leuz and Verrecchia (2000)
examine German firms that commit to higher disclosure levels by adopting International
Accounting Standards or U.S. GAAP and find that such firms experience a decline in the
information asymmetry component of the cost of capital, subsequent to adoption. Brown et al.
(2004) show that conference calls lead to long-term reduction in information asymmetry among
equity investors. Brown and Hillegeist (2007) find that disclosure quality reduces the likelihood
that investors discover and trade on private information.
If the disclosure revisions that result from the comment letter process are substantive,
then we would expect an enhanced information environment thereafter. Further, if an effect
exists, then ex ante it seems reasonable to expect cross-sectional differences along at least two
dimensions. First, the resolution of severe letters is more likely to improve the information
11
environment. For example, some letters may address a greater number of issues, thus creating a
cumulative impact. Or some letters could address an issue that is uniquely important. Neither
scenario is mutually exclusive, but it suggests that some measure of severity of the letter would
be related to the market effect arising from the resolution of the issue(s). Second, we conjecture
that the effect of the comment letters on the information environment of small firms is larger. On
average, small firms have poorer information environments. They generally have lower analyst
following and institutional ownership and are likely to have higher disclosure costs (Lang and
Lundholm 1993). This poor (pre-letter) information environment suggests that if there is any
impact created by the comment letters, then it should be relatively greater for small firms.
The effect of comment letters, if any, may extend beyond targeted firms. Peer companies
may mimic comment letter firm disclosure to adhere to industry norms or avoid review. Further
Big 4 audit firms may also encourage conformity across clients. If peers do mimic the
disclosures arising from comment letters, then the information environments of firms that do not
receive letters could be enhanced. We hypothesize that this indirect or spillover potential is most
likely where the SEC performs an intense review of a particular industry.
However, a long-standing economic question is the justification of regulating corporate
disclosures (Healy and Palepu, 2001). Schulte (1988) summarizes the paradox of regulation by
arguing that information is similar in nature to public goods, because it is difficult to exclude
others from using it and its consumption by one user does not diminish its availability to others.
Without regulation, public goods tend to be underproduced because of the free-rider problem.
The tendency in regulation, however, is to oversupply the public good, because users of
information always overstate their demand.
12
Based on Schulte’s (1988) argument, if the SEC is merely creating excess disclosure or
an oversupply, then comment letters should contain little substance and result in minimal
improvement in the firm's information environment. Given the high quality accounting
standards, disclosure requirements, and the requirement in the U.S. that public companies be
audited, we question whether there would be any benefit from an SEC review, which in
substance is merely the SEC staff reading the corporate filings.
Another rationale for why we might expect comment letters to have no economic effect is
regulatory capture theory, which suggests that regulated firms manipulate the agency responsible
for regulating them (see Dal Bo, 2006 for a review). If the SEC is subject to filer influence, then
comment letters may avoid substantive issues, thus creating no economic benefits. Ertimur and
Nondorf’s (2006) lack of results would support either of these rationales.
Some anecdotal evidence of the concern about the effectiveness of the comment letters
appears in the Commission’s own annual reports (2005 and 2006), in which they report various
metrics to track and report on SEC effectiveness. For comment letters, they state that they are
currently unable to quantify significant improvements or actions related to the letters (see
footnote for exact statement). 7
7 “For corporate filings, comments are issued to elicit better compliance with applicable disclosure
requirements and improve the information available to investors. Many instances, amendments involve financial restatements. Determination of “significance” stems from the nature of the change (e.g., restating positive income as a loss) or the size of the company. Analysis of divisions of corporation finance and management continued to work toward establishing a means for accurately tracking data on comments that result in significant enhancements in financial and other disclosures or other significant actions to protect shareholders. Divisions will provide data for this indicator once such tracking methods are in place.” See Exhibit 2.23 in the 2006 SEC annual report available at www.sec.gov.
13
In summary, whether the SEC’s review of registrant filings improves firms’ information
environment is an empirical question. On one hand, if the review process is successful in
enhancing disclosure to investors, we would expect a better information environment. This
improvement is likely to vary with the severity of the letter and the firm’s original information
environment. On the other hand, if any additional information required by the review is an
unnecessary oversupply or lacks substance, we would expect no change in the firms’ information
environment.
4. Research Design
To assess whether SEC oversight enhances firms’ information environments, we compare
market behavior around earnings releases for the two quarters before and after the receipt of an
SEC comment letter. Our focus on earnings announcement reactions as a proxy for firms’
information environment is motivated by theoretical work of Diamond and Verrecchia (1991)
and Kim and Verrecchia (1991a, b; 1994; 1997). These papers show that stock price reaction to a
public announcement decreases with the precision of pre-announcement information. Therefore,
a decrease in return volatility around earnings announcements indicates an improvement in the
pre-announcement information environment. These papers further show that stock trading
volume arises from differences in the quality (precision) of investor’s private information.
Consequently, a reduction in trading volume around earnings announcements reflects less
information asymmetry across investors and greater consensus regarding firm value. Several
14
papers in accounting and finance have used a similar approach to study information environment
changes.8
4.1 Baseline model
We measure stock price reaction as the four-day absolute cumulative abnormal return
(ACAR) around quarterly earnings announcements. We define the earnings announcement date
as day zero (� = 0), and compute ACAR as ���� = | ∏ (1 + ��) − 1| 2
��1 where we compute
AR as the abnormal return based on one-factor market model residuals estimated over the period
t-11 to t-200 trading days. CAV is the four-day cumulative abnormal trading volume around the
quarterly earnings announcement.9 We define abnormal trading volume as the difference
between announcement-window (-1, +2) trading volume and the mean of pre-announcement
window (-200, -11) trading volume, normalized by the mean volume.
To test the effect of the SEC oversight on the information environment, we employ the
following model:
������ �������� = �0 + �1������� + �2�������_���� + ������!� + " (1)
where Market Reaction is either absolute return or volume reaction to earnings announcements;
ComtLtr equals one if the firm receives a SEC comment letter, and zero otherwise; and
8 For example, Heflin, Subramanyam and Zhang (2003) use return volatility around earnings announcements to study the change in the flow of financial information to the capital markets before and after the implementation of Regulation FD. Another FD study, Bailey et al. (2003) use return and volume reactions to investigate the information environment change around the standard. Bailey et al. (2006) use return and volume reactions around earnings releases to study the change in a firm’s information environment when it cross-lists in the US market. 9 Some papers in the trading volume literature use a “volume market model” in the preannouncement window to calculate expected trading volume (e.g., Tkac (1999); Bailey et al. (2006)). We opt not to follow this approach because given the highly skewed volume data, a linear model tends to poorly specify the underlying data structure. Moreover, such model requires more computational cost but provides little improvement in power (Bamber, Barron and Stevens 2009).
15
ComtLtr_Post equals one if the firm receives a letter and the observation is from the post-letter
period, and zero otherwise. We define the pre-letter period as the two quarters before the date of
the first letter and the post-letter period as the second quarter after the date of the last letter. We
omit the first quarter after the letter to ensure that the equity market has been exposed to any
change in disclosure. We require the comment letter firms to have both a pre-letter and a post-
letter observation.
In Equation (1), β0 measures the average market reactions of the benchmark firms, β1
captures the difference in market reactions between the comment letter firms and the benchmark
firms, and β2 captures the change in market reactions for comment letter firms. If the SEC’s
review process substantively improves corporate disclosures, then we would expect more muted
market responses to earnings announcements following the resolution of the letters, which would
be reflected by a negative β2. In contrast, if the additional information resulting from the review
process is just an oversupply, then we would expect no change in market responses and thus β2 to
be indistinguishable from zero.
Consistent with earlier studies, we include a set of control variables related to market
behavior around earnings announcements, all of which we discuss in the results section. We
estimate Equation (1) with industry fixed effects, where we define industry as in Fama and
French (1997). We cluster standard errors by firm and year to correct for possible correlations
across observations (Rogers, 1993; Petersen, 2009).
To investigate whether the change in the information environment varies with the
severity of the letters, we alter Equation (1) by replacing the comment-letter dummy with a
variable based on the severity of letter content. We use the duration of the letter period as our
16
proxy for the seriousness of the letter content. We conjecture that if it takes longer to resolve the
comment letter issues, then the issues are more likely to be substantial, or there are more issues
to resolve, or both.
The change in a firm's information environment is also likely to vary with the firm’s pre-
letter information environment. We use firm size as our proxy for a firm’s original information
environment. To capture the differential effects, we partition the comment letter dummy in
Equation (1) into three size dummies.
4.2 Comment letter selection issues
If a firm receives an SEC comment letter, it is unlikely to be a random event. For
example, Section 408 of the SOX identifies various firm characteristics for consideration by the
SEC staff in choosing which companies to review. Therefore, certain types of firms are more
likely to attract the SEC’s attention. In addition, firms with certain characteristics may be more
likely to have reporting deficiencies and hence, receive a letter. This non-random treatment
assignment implies that there may be systematic differences between firms that receive a SEC
letter and firms that do not. The systematic differences could lead to biased estimates of the
treatment effect, i.e., changes in market reactions to earnings announcements.
One way to address the selection concern would be to construct the benchmark control
sample based on firms subject to SEC review, but for which no letter is issued. However, we are
unable to identity all the firms the Commission chooses to review.10 Hence, we construct the
10 Despite making several phone calls to the Division of Corporate Finance and also requesting the data under the Freedom Of Information Act.
17
benchmark control sample based on firms not receiving a letter in the year, i.e., these firms can
either have been reviewed by the SEC but did not receive a letter or not have been reviewed at
all. However, we further screen the benchmark firms, which we describe next.
We start by building the determinant model which relates firm characteristics to the
probability of receiving a letter.11 The firm characteristics we consider are those listed on Section
408 of the SOX and also the firm’s operating uncertainty and audit quality. We conjecture that
firms are more likely to get a comment letter if they fall under the SOX Section 408 criteria and
are more subject to reporting errors. For every year, we run a logit model and assign each firm a
predicted probability of receiving a comment letter in that year. Then we require both the
comment letter firms and the benchmark firms to have a common predicted probability range.
We remove firms that fall out of the range and exclude any unmatched comment-letter firm.
In addition, we conduct several robustness tests. First, we apply a standard two-stage
Heckman model. The first stage is a probit regression that models the probability of receiving a
letter. The second stage is Equation (1) augmented with the inverse Mills ratio from the probit
model to control for any self-selection bias.
Second, we use propensity score matching to select a matched control sample. We then
conduct a difference-in-difference test, examining the change in the information environment
between the comment-letter sample and the matched control sample. The propensity score for a
firm is the probability of receiving a SEC comment letter conditional on the firm’s observable
characteristics. Propensity score matching provides two advantages. First, it allows us to control
11 (See Section 5.2)
18
for many company covariates simultaneously by matching on a single scalar variable (i.e., the
propensity score), and second, we can create a quasi-randomized experiment (D’Agostino,
1998). If we find two firms, one in the comment letter group and one in the control group, with
the same propensity score, then it is as if these two firms were randomly assigned to each group
in the sense that they are equally likely to be treated or control (conditional on the observed firm
characteristics). Each matched control firm has a hypothetical comment letter period based on
the corresponding comment-letter firm.
The difference-in-difference model is:
������ �������� = �0 + �1���� + �2������� + �3������� ∗ ���� +
+ ������!� + "
(2)
�1 captures how both treatment and control firms are influenced by time. The time-invariant
difference, if any, in information environment between the treatment and the control is captured
by �2. β3 represents the differential change in information environment between the comment
letter firms and the matched control firms. If the SEC’s review process is effective in enhancing
a firm’s information environment, then we would expect �3 < 0.
The difference-in-difference design ensures that our results are not driven by some
unspecified macro time trend. However, propensity score matching is also subject to the
limitation that it can only remove selection biases based on observable firm characteristics. It is
less robust to (unobservable) omitted conditioning variables than the Heckman approach
(Heckman and Navarro-Lozano, 2004). Since the Heckman and the matching approach have
their own strengths and weaknesses, we use both to test the robustness of our findings.

5. Data and comment letter determinants
5.1 Sample description
We search EDGAR, the SEC database of public company filings, for comment letters
relating to 10Qs and 10Ks. For the period 2003 to 2006 we obtain 9,212 letters relating to 4,138
cases for 3,818 firms.
Table 1, Panel A summarizes the sample selection process. Of the 3,818 firms in our
sample, there are 307 firms that have 627 cases. For our pre- and post-letter research design, we
want to ensure that issues are fully resolved in the post-letter period. Therefore, for these 627
cases, we use two criteria to decide whether the later cases are actually a continuing investigation
of an earlier case and hence the two should be combined. First, if the two cases have overlapping
letter periods, we consider them as one case. We find 90 cases meet this criterion and merge
them into 45 cases. Second, if the period between the end date of the earlier case and the
beginning date of the later case is less than six months, 232 cases meet this criteria. Merging
these cases reduces the number of cases by 118. (Two firms have three cases and one has four
cases.) In addition, we require the 3,818 sample firms have a Compustat GVKEY. This
requirement eliminates 903 firms and 921 cases. Our selection process results in a final sample
of 3,054 cases that represent 2,915 firms.
Table 1, Panel B shows that most of the cases in the sample arise in 2005 and 2006. This
time clustering exists because the SEC began publicly disclosing comment letters in 2005 and
only intended to post letters relating to filings made after August 1, 2004. Panel C shows that the
majority of the sample firms are the focus of only one SEC investigation. Out of 2,915 firms,
only 135 firms are the subject of two cases and two firms are the subject of 3 cases. In Panel D,
20
we see that on average, a case lasts for 69 days and has two comment letters. Panel E reports the
industry distribution of both comment letter firms and the Compustat universe in the sample
period. The industry classification follows Fama and French (1997). Insurance is slightly over-
represented among comment letter firms (4.32% compared to 2.66%), and utilities are slightly
underrepresented (2.95% compared to 4.05%). Otherwise, letter representation appears to be
proportional.12
5.2 Determinants of receiving an SEC comment letter
Whether a firm receives an SEC comment letter in a particular year depends on whether
the firm is selected for review in that year and its reporting quality. We develop our determinant
model based on these two factors.
Our proxies for the SOX review criteria follow. Restate is a firm’s restatement history,
which we define as the number of restatements the firm has filed based on the Government
Office of Accountability database. We measure a firm’s price volatility as its idiosyncratic
volatility in the stock market so %&���'�������(�! = ln (1�)2
)2), and �2 is the R-square from the
market model estimated one year prior to receiving the comment letter (Durnev et al., 2004;
Ferreira and Laux, 2007). This proxy is relative to market-wide variation which we believe best
captures the SOX criteria. MarketCap is the firm’s market capitalization at the fiscal year-end
12 In untabulated analysis we explore the market reaction when a firm receives the first comment letter from the SEC. Of 2,915 firms, we are able to find 2,324 firms (2,376 cases) with non-missing return data on the first letter date. We find no statistically significant stock market reaction in terms of either daily abnormal return or cumulative abnormal return over (-1, +2). This result is not surprising, since the existence of an SEC enquiry is unknown to the public until the case is resolved and the SEC releases the letters. Obviously, we are interested in the market reaction on the date that the SEC releases the letters, but we do not have those dates of release.
21
prior to receiving a comment letter. To measure whether a firm is an emerging company with a
disparate PE ratio, we include a firm’s age and its earnings-per-share (EPS) to share price ratio
(E/P). Age is the number of years the firm appears on CRSP. E/P is calculated at the fiscal year-
end prior to the comment letter. We use the E/P ratio rather than a P/E ratio because some of the
sample firms have zero earnings. To measure the impact of a firm’s operation on any material
sector of the economy, we calculate each company’s proportion of their respective industry
revenue at the fiscal year end prior to the comment letter and denote the variable as
RevProportion. We define industries based on their two-digit SIC codes.
In addition to the SOX review criteria we include factors that relate to a firm’s reporting
quality. First, firms with high uncertainty in their operating environment are likely to use greater
estimation and more approximations in their financial reports. Accordingly, we expect such firms
to be more subject to reporting errors. We use the volatility of a firm’s operating cash flow as our
proxy for operating uncertainty. CFOVol is the standard deviation of cash flows from operation
(CFO) over the five years prior to receiving the comment letter. We scale CFO by total assets.
Dominant audit suppliers are likely to provide higher quality audits because they have more
resources and also face a greater risk to their reputation if they conduct poor-quality audits. We
expect companies audited by these large audit firms to have higher reporting quality, and hence
to be less likely to receive a comment letter. The dominant audit suppliers in our sample period
are the so-called "Big 4" public accounting firms: Deloitte and Touche, Ernst and Young,
KPMG, and PricewaterhouseCoopers. Big4 equals one if the firm is audited by one of these audit
firms and zero otherwise.
22
Of the 3,054 comment letter cases, 2,190 have complete data for the determinant
variables. There are 9,098 non-comment-letter firm-years in Compustat that have similarly
complete data. Table 2, Panel A provides descriptive statistics and the results of the univariate
tests we use to compare firms that receive an SEC comment letter with those that do not. For
comment-letter firms, we measure all variables prior to the date of the first letter. For non-
comment-letter firms, we measure all variables at the prior year’s fiscal year-end date.
On average, we find that firms that receive an SEC comment letter are more likely to
have a restatement history and lower idiosyncratic volatility, be larger in market capitalization
and represent a larger proportion of their industry revenue, have been listed longer, and have a
higher E/P ratio (median only). The univariate results on operating cash flow volatility that we
use as a proxy for operating uncertainty are mixed; the average CFOVol of the comment letter
sample is significantly larger than the non-comment-letter sample, while the median CFOVol of
the comment-letter firms is significantly smaller than the non-comment-letter firms. We find no
significant difference in the proportion of comment letter firms and non-comment-letter firms
that are audited by a Big 4 audit firm.
Panel B of Table 2 presents Pearson correlations. The largest significant correlations are a
negative correlation of -0.377 between Big4 and IdiosyncraticVol, followed by a positive
correlation of 0.259 between RevProportion and MarketCap. The majority of other correlations
fall between ±0.15, which suggests that the variables included in our determinant model capture
distinct firm attributes.
We model the probability of a firm receiving a comment letter as a function of the above-
mentioned firm characteristics by using the following logistic regression.
23
���,(�������) = -(�0 + �1������� + �2%&���'�������(�!
+�3��������. + �4��/���.������ + �5�0�
+�61� + �7�23(�! + �84�04)
(3)
Panel C of Table 2 presents the results. In addition to the coefficient estimates, we calculate the
marginal effect of each variable. Doing so can provide insight into which firm attributes are most
important in determining the likelihood of receiving a letter from the Commission. We find that
share of industry revenue has the largest marginal effect on the probability of receiving an SEC
comment letter. This result suggests that the SEC pays more attention to these firms because they
play an important role in the economy. A previous restatement and large P/E disparity also
increase the probability of receiving a letter. However, inconsistent with the SOX guideline, we
find that older firms are more likely to receive a letter. And we find that firms with a more
uncertain operating environment, as reflected in the operating cash flow volatility, face a higher
probability of receiving a letter. Our determinant model yields a Wald 52 of 124.81, which is
significant at the 1% level or better.
Overall, the univarite analyses and the logit model results in Table 2 suggest that the SEC
tends to pay more attention to industry leaders and more established firms and firms that have a
restatement history and higher operating uncertainty.
6. Market reactions to earnings announcements
Following Heflin, Subramanyam, and Zhang (2003), in Figure 1 we plot the mean
absolute cumulative abnormal returns (ACARs) from 64 trading days (the approximate number
of trading days in a quarter) before to two days after earnings announcements for both the pre-
24
and post-comment-letter periods. The post-comment-letter ACARs are consistently smaller than
are their pre-comment-letter counterparts, as reflected in the line below in Figure 1. Since
ACARs represent the information gap between the pre-announcement price and the full-
information post-announcement price, the figure suggests a reduction in the information gap
after the comment letters, and therefore an enhanced pre-announcement information
environment.
6.1. Changes in market reactions
Our requirement that comment-letter and benchmark firms have a common range of
predicted probability of receiving a letter in the year leaves 2,070 comment-letter firms and
3,832 benchmark firms. We further require non-missing data from Compustat, CRSP, and IBES,
so for the share price volatility test, our sample includes 1,286 comment-letter firms and 2,067
benchmark firms. For the trading volume test, we have 1,897 comment-letter firms and 3,540
benchmark firms. The price volatility test sample is smaller because it requires IBES data.
Panel A of Table 3 provides descriptive statistics for the market reaction variables. The
univariate comparisons show a decline in both ACAR and CAV for the comment-letter firms
following resolution of the letter, although only the ACAR change is statistically significant. On
average, we see no difference in ACARs between benchmark firms and comment-letter firms
prior to the letter, but we do observe larger CAVs for the comment-letter firms. Comparing the
post-comment-letter reactions for comment-letter firms to the benchmark firms, we see lower
ACAR reactions for comment-letter firms and no statistically significant difference in CAV
reaction.
25
Panels B1 and B2 of Table 3 present the regression results when we use ACAR as the
dependent variable. We present nine columns of analysis. In Panel B1, Columns (1) and (2), we
present the baseline model, with and without industry fixed effects respectively; in Columns (3)
and (4) we present some robustness tests. Panel B2 presents the additional analyses that we use
to address the potential selection bias problem, and also the cross-sectional analyses based on
letter severity and firm size. The results of the baseline model show that, after controlling for
various firm characteristics, the price reactions of the comment-letter firms are significantly
different from those of the benchmark firms as the coefficients on ComtLtr are positive and
significant. More importantly, for comment-letter firms, the price reactions become significantly
lower after the receipt of an SEC comment letter as the coefficients on ComtLtr_Post are
negative and statistically significant at the 1% level.
To give a sense of the magnitude of the changes in ACARs, we compare the coefficients
on ComtLtr_Post with the sum of the coefficients on the constant and on ComtLtr. The
comparison using the coefficients in Column (1) indicates that comment-letter firms experience a
decrease of about 155% in ACARs. Column (2) shows that including the industry fixed effects
reduces the magnitude of the decline to 32%.
The control variable coefficients generally have the expected sign. Firms with inherently
higher price volatility tend to have higher price reactions around earnings releases, as indicated
by the positive coefficients on RetVol and NegCar (Heflin et al. 2003; Black, 1976; Christie,
1982; Nelson, 1991). The positive coefficients on AbsCar suggest that larger information flow
yields greater market reactions (Heflin et al., 2003). The coefficients on Loss are negative and
significant, consistent with the theory that the market reacts less when the earnings numbers are
26
less informative (Hayn, 1995). The coefficients on Size are negative, suggesting larger reactions
for smaller firms (Atiase, 1985). For smaller firms, investors may have less incentive to gather
pre-disclosure information, and therefore the market reacts more to an earnings shock. We do not
find that bond yield (Collins and Kothari, 1989) or analyst forecast error are significant in our
specification. The results of Columns (3) and (4) in Table 3 confirm that these results are robust
to using only the one quarter before the comment letter in contrast to two in the earlier
specification (balanced panel). Our results are also robust to calculating the abnormal return
market model only once, just prior to the comment letters (no overlap) for both the pre- and post-
comment-letter reactions.
Panel B2 begins with a standard Heckman model. Column (1) presents the probit model
results. The results are consistent with those presented in Section 5. Large industry leaders and
firms with a restatement history are more likely to receive an SEC comment letter. Column (2)
presents the second-stage OLS results. The coefficient on the inverse Mills ratio, λ, is significant
and positive, indicating the presence of an upward selection bias toward the coefficient on
ComtLtr. After including the inverse Mills ratio, the coefficient on ComtLtr switches from
positive (Panel B1 column (2)) to negative. More importantly, the coefficient on the
ComtLtr_Post term remains negative and significant. After correcting for the potential selection
bias, we find an 87.5% reduction in return volatility for post-comment-letter earnings events.
In addition, we select a propensity-score-matched control sample and conduct a
difference-in-difference test. Among the 1,286 comment-letter firms in the return volatility test,
we find matches for 1,227 firms. After the match, the means of all the determinant variables
(Restate, IdiosyncraticVol, MarketCap, RevProportion, Age, E/P, CFOVol, and Big4) are not
27
significantly different between the comment letter firms and the control sample firms (not
tabulated). This lack of differences confirms that the matching successfully removes observable
systematic differences between the two samples.
Column (3) of Panel B2 presents the matched sample results. The coefficient on ComtLtr
is no longer significantly different from zero, which further confirms that the matched control
sample has firm features similar to those of the treatment sample. The coefficient on Post is also
not significant, indicating that the control firms do not experience any change in their abnormal
return reactions to earnings announcement. The sum of the coefficients on Post and ComtLtr x
Post is negative and significantly different from zero (p-value = 0.0043), implying a decline in
ACARs for comment-letter firms. The coefficient on the interaction term ComtLtr x Post
captures the difference-in-difference between the comment-letter firms and the control firms and
it is negative and significant at the 1% level. The results of all four analyses consistently show
that companies generally experience a reduction in return reactions around earnings
announcements after the resolution of SEC comment letters. The reduced reactions imply an
enhanced pre-announcement information environment and a smaller information gap between
firm managers and investors.
In Table 3, Columns (4) and (5) of Panel B2 we present the cross-sectional analysis using
the matched sample. As our proxy for letter severity we use the time to resolve the comment
letter case. We introduce two dummy variables, Severe for cases that are the top decile of the
distribution, and Non-Severe for the others. Although the Column (4) results are consistent for
both groups, the reduction magnitude is much greater for the severe cases as the interactive post
coefficient is -0.018 compared to -0.006 for the non-severe cases.
28
We also split the sample into three groups based on market capitalization and present the
results in Table 3, Column (5). The results show that the comment-letter effect is concentrated in
the small firm group. These firms likely have a lower-quality initial information environment.
However, regulatory capture theory is an alternative explanation for our size results. If larger
firms have influence over the SEC that small firms do not, then they may be able to avoid any
substantive changes required from a review.
In Panels C1 and C2 of Table 3, we present the results where abnormal trading volume is
the dependent variable. In these models, we control for the contemporaneous price reaction
because prior research finds a positive association between volume reaction and the same
window price reaction (e.g., Kim and Verrecchia 1991a, 1997; Atiase and Bamber 1994). ACAR
is the absolute value of the cumulative abnormal return in the announcement window (-1, 2).
Given the importance of the relation between ACAR and trading volume, we also allow the
coefficient on ACAR to differ in the pre- and post-comment-letter period. Consistent with prior
research, we find that ACAR is positively associated with volume reactions. Similar to the price
reaction specification, we control for the amount of surprise to investors. However, rather than
using analyst forecasts as our proxy for investor expectations, we use last year’s quarterly
earnings since Bamber (1986) shows that price reactions to earnings announcements is best
related to analyst-based unexpected earnings, while trading volume reactions is more related to
random-walk based unexpected earnings. EarnSurprise is the absolute value of seasonal changes
in earnings per share deflated by price at the end of the quarter. Surprisingly, we find no relation
to earnings surprise.
29
The structure and presentation of Panel C is similar to Panel B. The baseline model
(Columns (1) and (2)) show that the coefficients on ComtLtr_ Post are significant and negative,
indicating a reduction in abnormal trading volume around earnings releases for comment-letter
firms. The results imply that the SEC comment letters are effective in enhancing disclosure
levels, which leads to a lower divergence of opinion among investors. The results shown in
Column (3) confirm that our results are robust to using only the quarter before the comment
letter (balanced panel). However, the results do not hold when calculating the abnormal volume
model strictly prior to the comment letters. We believe this result arises due to the time series
trend of increasing trading volume.
Panel C2 presents the test results which control for selection bias as well our cross-
sectional analysis. The baseline model result is robust to a Heckman self-selection bias
correction shown in Column (2). Of the 1,897 comment-letter firms in the volume test, we are
able to find 1,873 matched control firms. Column (3) shows the difference-in-difference results
with the matched control sample. The coefficient on ComtLtr x Post becomes insignificant in this
specification. The cross-sectional analysis shows that the lack of results in Column (3) seems to
be in part atrributable to the non-severe cases, which show no change in Column (4) in contrast
to the severe cases. We do not find any cross-sectional differences by firm size (Column 5).
We find some evidence of a trading volume decline following comment letters, but the
results are sensitive to the specification and the effect appears to be strongest for the severe cases.
30
6.2 Industry externality
The previous results suggest that once the SEC’s comments are resolved, comment-letter
firms experience a reduction in price and volume reactions around earnings announcements. The
lower reactions imply an enhanced information environment and an effective SEC review
process. In this section, we explore whether the SEC review process creates an industry spillover.
We define industry peers as all companies in the same four-digit SIC industry level as
comment-letter firms that do not receive a comment letter in the same year. We further require
any industry year to have at least five firms. For every year, we denote an industry comment-
letter period as starting from the earliest date of all the cases issued to the industry in that
industry year and ending on the last date of those cases. We define the pre-comment-letter period
for the industry peers as the the two fiscal quarters before the starting date of the industry
comment-letter period and the post-comment-letter period is the second fiscal quarter after the
end date of the industry comment-letter period. After we apply the data requirements, we are left
with 861 comment-letter firms and 1,331 industry peers for the return volatility test; for the
trading volume test we have 1,424 comment letter firms and 2,499 industry peers.
Panel A of Table 4 reports the regression results of changes in return reactions. In
Columns (1) and (2), we compare the change in return reactions among peer firms. In Column (1)
the coefficient on Post is not statistically significant, indicating that on average, peer firms
experience no change in their information environment, suggesting no positive industry
externality. However, Column (1) does not differentiate between whether or not the industry is
receiving intense SEC attention. We investigate this possibility in Column (2). We define an
industry as receiving intense SEC attention if the industry has received more than eight
31
comment-letter cases in the year. Eight represents the upper quartile. We partition the Post
dummy into Post_ Intense, and Post_ Nonintense, according to the industry group to which each
firm belongs. The results indicate that peer firms in nonintense industries do not experience any
change in their return reactions around earnings announcements, however, peer firms in intense
industries experience a decrease in theirs. The negative and significant coefficient on
Post_Intense provides some evidence that issuing comment letters creates positive industry
spillover, and that firms in industries to which the SEC reviews intensely improve their
information environment even without receiving a letter.
In Table 4, Columns (3), (4), and (5), we compare the change in return volatility between
peer and comment letter firms. If the externality is strong, then the reduction in return volatility
for the industry peers may be the same as comment-letter firms. Column (3) presents the overall
results. The coefficient on Post x Treat is negative and significant, suggesting that the decrease
in return reactions is larger for firms that actually receive a letter. The coefficient on Post is not
significant. Peer firms do not experience any change in their price reactions, on average. From
the results of Columns (1) and (2), however, we know that the nonsignificance of Post comes
from peer firms in the nonintense industries.
Therefore we examine intense industries and nonintense industries seperately. Column (4)
presents the results for intense industries. Consistent with the result in column (2), the coefficient
on Post is negative and significant: firms in intense industries experience a reduction in return
reactions even without receiving a comment letter. The nonsignificant coefficient on Post x Treat
indicates that comment-letter firms and peer firms experience a similar decrease in return
reactions.
32
Column (5) shows that peer firms in nonintense industries do not experience any change
in return reactions, and that comment-letter firms experience a greater decrease in return
reactions. The evidence of an industry spillover suggests that the Table 3 results may actually
understate the comment-letter effect, since the benchmark or control firms are also affected by
SEC oversight, thereby reducing the contrast between comment-letter and peer firms.
We repeat the externality analysis with trading volume as the dependent variable and
present the results in Panel B of Table 4. From Columns (1) and (2), we find that peer firms do
not experience a decrease in their trading volume reactions. When we compare the decrease in
volume reactions between peer firms and comment-letter firms in Columns (3) – (5), we find that
whether or not a firm receives a comment letter makes no difference. These results differ from
Table 3 due to the different sample applied for each.
In summary, Table 4 documents some evidence of a positive industry externality from
comment letters. Peer firms who do not receive a letter but are in the same industry as comment
letter firms receiving intense SEC scrutiny also experience a reduction in return reactions around
earnings releases and the magnitude of the reduction for industry peers is equivalent to that for
comment letter firms.
7. Conclusion
We study both the direct and indirect impact of SEC comment letters on the information
environment of firms by examining stock market reactions to earnings announcements before
and after a firm resolves a letter. Our sample includes 2,915 firms that receive comment letters in
the 2003-2006 period. Our results provide evidence consistent with a change in the firm’s
33
information environment following a comment letter. This change is evidenced by lower
abnormal return volatility and trading volume around ensuing earnings announcements.
Generally, our results are robust to correction for potential selection bias associated with which
firms receive a letter. However, the trading volume results appear to be concentrated in
comment-letter cases that are severe. Moreover, we find some evidence that there is an industry
spillover effect. We find that industry peers that do not receive letters also experience benefits,
suggesting that they adopt disclosure changes of comment-letter firms. Hence, we conclude that
the SEC comment letters enhance the quality of firms’ accounting and disclosure, which results
in improved information environments.
Our paper provides what we believe is the first large-sample evidence on the financial
reporting oversight role of the SEC. We find that regulators can improve firms’ information
environment by monitoring corporate reporting. These results contrast with recent papers that
suggest no benefit to public enforcment (La Porta et al. (2006); Djankov et al. (2008a)). Our
findings could be of interest to policy makers, both domestic and foreign, as well as the SEC
who wish to evaluate the effectiveness of this regulatory effort.
We note that our paper is not without its limitations. Our sample of SEC comment letters
is clustered in a short time frame and hence the generalizability of our results may be a concern.
In addition, the SEC comment-letter process has many different objectives (see Section 2) and
thus may create other effects that we do not explore.

Figure 1
Price Discovery Before and After Comment Letters
The figure depicts mean absolute cumulative abnormal returns (ACAR) around earnings announcements pre- and post-comment letters. We define the earnings announcement as day 0. ACAR is the absolute value of daily abnormal returns summed over (-t, +2), where abnormal returns are one-factor market model residuals estimated over (-200, -11).

IdiosyncraticVol is the logistic transformed relative idiosyncratic volatility estimated from the market model over the prior year. MarketCap is the firm’s market capitalization (in $millions) in the prior year. RevProportion is the firm’s share of industry revenue in the prior year. Age is the number of years the firm appears on CRSP. E/P is the EPS-to-Price ratio at the end of the prior year. CFOVol is the standard deviation of cash flows from operation over the prior five years. Big4 equals one if the firm is audited by the big 4 audit firm, and zero otherwise. For comment letter firms, we measure all variables prior to the date of the first letter. For non-comment-letter firms, we measure all variables at the prior year’s fiscal year end date. In Panel B bold text indicates significance at the 0.05 level or better. White heteroskedastic consistent standard errors are in brackets. t-statistics are clustered by firm . ***, **, and * indicate significance at the 1%, 5%, and 10% levels, respectively (two-tailed).

Table 4
Industry Externality
This table reports industry externality of SEC comment letters. Panel A presents changes in absolute cumulative abnormal returns (ACAR) among industry peers. Panel B presents changes in abnormal trading volume (CAV) among industry peers. ACAR is the four-day absolute value of daily abnormal returns summed over (-1, +2), where abnormal returns are one-factor market model residuals estimated from day -200 to day -11. CAV is the four-day abnormal trading volume summed over (-1, +2), where abnormal trading volume is the difference between trading volume and the mean of daily volume over the (-200, -11) window, normalized by the mean volume. RetVol is the standard deviation of the firm’s returns during the market model estimation period. NegCar equals one if the cumulative abnormal return over the window (-64, +2) is negative, and zero otherwise. AbsCar is the absolute value of the cumulative abnormal return over the window (-64, +2). Loss equals one if the firm reports a loss in the quarter, and zero otherwise. EarnSurprise is the absolute value of seasonal changes in earnings per share deflated by price at the end of the quarter. BondYield is the yield on the CRSP 30-year bond index at the end of the quarter. ForecastError is the absolute value of analyst forecast error deflated by price at the end of the quarter. Size is the firm’s market capitalization at the end of the quarter (in $millions). Intense equals one if the industry has received more than eight comment letter cases in the year, and zero otherwise. Nonintense equals one if the industry has received less than eight comment letter cases in the year, and zero otherwise. We define industry by 4-digit SIC codes. Post is the earnings announcement following resolution of the letter. White heteroskedastic consistent standard errors are in brackets. t-statistics are clustered by firm and by year. ***, **, and * indicate significance at the 1%, 5%, and 10% levels, respectively (two-tailed).
