    1. Introduction

    The revelations of serious accounting problems around the turn of the mil-

    lennium at several prominent companies such as Enron, Worldcom, Tyco and

    Healthsouth were watershed events. Following these scandals, a number of

    other companies admitted to having accounting problems of their own. Most

    experienced large stock price declines upon announcing that misstated ¯-

    nancial reports would be restated (see, e.g., Palmrose et al., 2004; Agrawal

    and Chadha, 2005). A number of companies acknowledging misstatements,

    including Enron and Worldcom, were forced into bankruptcy. Many were

    defendants in lawsuits ¯led by investors, customers, suppliers and employees

    (see, e.g., Palmrose and Scholz, 2004).

    Lawmakers have responded to these scandals by adopting the Sarbanes–

    Oxley Act of 2002, whose tough corporate governance rules apply to all com-

    panies with stock listed in the U.S. In addition, the New York stock exchange

    (NYSE), Nasdaq, and American stock exchange (AMEX) adopted new cor-

    porate governance rules as part of their listing requirements. These scandals

    also resulted in signi¯cant changes in the audit industry. The Arthur Andersen

    partnership dissolved after its criminal indictment on charges of obstructing

    the federal investigation of the Enron scandal, and several large audit ¯rms

    divested their consulting businesses to eliminate potential con°icts of interest

    that could undermine their credibility as auditors.

    In addition to the consequences to restating companies, these scandals can

    have signi¯cant consequences to top management (i.e., the chief executive

    o±cer (CEO), Chairman and President) and outside directors (see, e.g., Desai

    et al., 2006; Srinivasan, 2005). However, there is yet no systematic evidence on

    the consequences to the two parties closest to the ¯nancial reporting process,

    namely top ¯nancial managers and external auditors. This paper attempts to

    ¯ll this gap in the literature. In addition, we extend Desai, et al.'s evidence on

    top management turnover by examining a larger sample of restatements.

    Finally, we analyze sub-samples where restatements are likely to have greater

    consequences. Our study focuses on two important outcomes of the func-

    tioning of internal governance mechanisms, namely management and auditor

    turnover, during a time of intense corporate turmoil.

  • Anecdotal evidence is mixed on whether an accounting scandal leads to

    greater management and auditor turnover. In certain high-pro¯le cases, top

    management, the chief ¯nancial o±cer (CFO) and outside auditors all lost

    their positions following the scandals. For example, Enron's CEO, Je®rey

    Skilling, unexpectedly resigned in August 2001, less than three months before

    the company's accounting problems were publicly revealed. Enron's CFO,

    Andrew Fastow, was ousted in October 2001. Kenneth Lay, who resumed the

    CEO position when Skilling left, resigned in February 2002. Enron's long-time

    auditor, the Big Five accounting ¯rmArthur Andersen, dissolved after criminal

    indictment. Worldcom CEO, Bernard Ebbers, resigned shortly after his ¯rm's

    $3.8 billion accounting fraud became public. In addition, Worldcom ¯red its

    CFO, Scott Sullivan and its auditor, ArthurAndersen. Similarly, Healthsouth's

    board voted unanimously to ¯re its chairman and CEO, Richard Scrushy, less

    than two weeks after the company revealed a massive accounting fraud.

    Healthsouth also ¯red its CFO and its auditor, Ernst and Young. These

    departures received extensive media coverage. Less known are the numerous

    other scandals that did not prompt any changes inmanagement or auditors. For

    example, ¯rstUSA Inc., 3Com,Boston Scienti¯c, andBausch andLomb did not

    replace their CEOs, CFOs or auditors after revealing accounting problems.

    As these examples show, the consequences to top management, top ¯-

    nancial o±cers and external auditors of ¯rms involved in accounting scandals

    can be dramatically di®erent. In this paper, we provide systematic evidence

    on this issue. In doing so, we seek to shed some light on competing theoretical

    arguments about these consequences.

    Managerial changes entail signi¯cant costs and bene¯ts for a ¯rm. One

    would expect a ¯rm to replace management if the bene¯ts exceed the costs.

    Agrawal et al. (1999) discuss several reasons for greater management turn-

    over in ¯rms accused of fraud. These reasons also apply to accounting

    scandals. First, restating ¯rms may be more inclined to replace top man-

    agement and top ¯nancial o±cers in order to regain or reestablish reputa-

    tional capital that is often lost when accounting scandals occur. Second,

    restating ¯rms face greater risk of securities class action lawsuits from

    shareholders; replacing managers can help ¯rms limit their liability exposure

    following restatements. Third, top management turnover increases following

    poor stock price performance (see, e.g., Warner et al., 1988). A substantial

    decline in market value upon restatement announcement can also trigger

    management turnover. Fourth, along similar lines, ¯rms experiencing ¯nan-

    cial distress tend to have high management turnover (see, e.g., Gilson, 1989).

  • The higher incidence of delisting or bankruptcy in restating ¯rms (see,

    Palmrose and Scholz, 2004) can also lead to greater management turnover.

    On the other hand, there are also reasons why an earnings restatement may

    not lead to greater management turnover. First, the cost of replacing a ¯red

    manager's accumulated ¯rm-speci¯c human capital may be prohibitive.

    Second, the level of internal controls needed to eliminate any possibility of

    accounting problems may be sub-optimal for a ¯rm. Because the direct and

    indirect costs (such as lost business) of such controls may be prohibitive, the

    revelation of accounting problems may not prompt the board to change

    managers, unless the problems are directly linked to those individuals. Third,

    while restatements generally are bad news for ¯rms, some restating ¯rms may

    not lose signi¯cant reputational capital because they did not have great

    reputations to begin with. In such cases, the net bene¯ts from replacing man-

    agers can be small. Finally, a ¯rm's internal governance mechanisms may not

    be strong enough to prompt management turnover (see, e.g., Jensen, 1993). So

    even though a restatement of earnings implies that management caused, ig-

    nored or failed to detect material misstatements, the restatement may not lead

    to greater managerial turnover.

    We also examine the e®ect of an earnings restatement on subsequent

    changes in the outside auditor. As in the case of top management, there are

    signi¯cant costs and bene¯ts associated with replacing the auditor. Replacing

    the auditor may be bene¯cial, if the change will help the ¯rm regain its

    reputational capital or limit its liability exposure. But the cost of replacing

    auditors can be large. First, new auditors often face steep learning curves.

    Second, the audit ¯rm also may be providing other services to the company

    such as tax, computer systems or management consulting, which may have

    synergies with auditing. These synergies are lost if the ¯rm replaces the

    auditor. Third, the company may face a limited choice of audit ¯rms that

    specialize in its industry, have the necessary scale and have o±ces near its

    headquarters. Signi¯cant replacement costs may explain why auditor turn-

    over is rare.

    We examine a sample of 518 U.S. public companies that announced

    earnings-decreasing restatements during the 1997–2002 period and an in-

    dustry-size matched sample of control ¯rms. We focus on restatements an-

    nounced pre-SOX. Post-SOX, a large number of companies restated to \clean

    house"; consequently, these cases tend to be less serious, as evidenced by

    negligible average stock price reactions to their announcements (see,

    e.g., Agrawal and Cooper, 2010). We ¯nd strong evidence that restating ¯rms

    have greater turnover of CEOs, top management and CFOs than control

  • ¯rms. The magnitudes of these e®ects are quite large. During the three-year

    period (�1, þ1), restating (control) CEOs, CFOs and top managementexperience turnover rates of 53% (34%), 65% (43%), and 85% (59%), re-

    spectively, where 0 is the year of restatement announcement. Using logistic

    regressions that control for other determinants of management turnover over

    the years (�1, þ1), CEOs, CFOs and top management of restating ¯rms facea 14%, 10% and 9% greater probability, respectively, of being replaced than

    those of control ¯rms. Compared to the usual turnover probabilities in non-

    restating ¯rms over this window, these represent increases of about 42%, 23%

    and 20%, respectively. The magnitudes of these e®ects are even larger for

    restatements that are more serious, have worse e®ects on stock prices, result

    in negative restated earnings, are initiated by outside parties, are accompa-

    nied by Accounting and Auditing Enforcement Releases (AAERs), or trigger

    securities class action lawsuits. We ¯nd little systematic evidence that

    auditor turnover is higher in restating ¯rms.

    Our paper complements the literature on the consequences to managers of

    enforcement actions by the U.S. Securities and Exchange Commission (SEC)

    or Department of Justice (DOJ) for earnings manipulation or ¯nancial mis-

    representation (see, e.g., Beneish, 1999; Karpo® et al., 2008a). As discussed

    by Agrawal and Chadha (2005), most earnings misstatements di®er from

    cases where regulators issue enforcement actions. Sta® and resource con-

    straints prevent regulators from pursuing all cases of earnings manipulation.

    To have the greatest deterrent e®ect, regulators target egregious violators

    and cases likely to generate greater media coverage (see, e.g., Feroz et al.,

    1991; Dechow et al., 1996; Agrawal and Chadha, 2005). While less serious

    than cases warranting enforcement actions, earnings misstatements permit

    larger sample sizes and avoid issues of selection by regulators. Related studies

    examine the consequences to managers and directors of corporate fraud

    accusations and securities class action lawsuits (see, e.g., Agrawal et al., 1999;

    Niehaus and Roth, 1999; Helland, 2006; Fich and Shivdasani, 2007). Our

    study also contributes to the broader literature on managerial disciplining

    surrounding other times of major corporate turmoil such as bankruptcy and

    corporate control events.1

    1See, e.g., Gilson (1989) for bankruptcies, Martin and McConnell (1991) and Agrawal andWalkling (1994) for takeovers, DeAngelo and DeAngelo (1989) for proxy contests, and Kleinand Rosenfeld (1988) for greenmail. Related work analyzes the interaction between internaland external governance mechanisms (see, e.g., Agrawal and Knoeber, 1996; Hadlock andLumer, 1997; Mikkelson and Partch, 1997; Huson et al., 2001).

  • The remainder of this paper is organized as follows. Section 2 brie°y

    reviews the literature on the causes and consequences of accounting manip-

    ulation, corporate fraud and other crimes. Section 3 describes our sample

    and data. Section 4 presents our empirical results for the full sample, and

    Section 5 reports the results for a number of sub-samples where the re-

    statement may have greater e®ects. Section 6 concludes.

    2. Prior Studies on the Causes and Consequences of Accounting

    Manipulation and Corporate Fraud

    Previous studies have examined the causes and consequences of three types of

    accounting manipulations. In decreasing degrees of seriousness, these are

    cases of earnings manipulation where the SEC brings enforcement action,

    restatements to correct ¯nancial misstatements, and earnings management.2

    Other studies have investigated a variety of corporate frauds and crimes. We

    brie°y review the literature on the causes and consequences of these four

    types of infractions.

    2.1. Causes

    2.1.1. SEC accounting enforcement actions

    A seminal paper by Dechow et al. (1996) examines the motives and causes of

    earnings manipulation that resulted in SEC enforcement actions. The SEC

    announces these actions via AAERs. Dechow et al. ¯nd that ¯rms with weak

    corporate governance are more likely to manipulate earnings to lower the cost

    of external ¯nancing. Beasley (1996) also ¯nds evidence of governance

    weaknesses in ¯rms subject to SEC enforcement. Beneish (1999) ¯nds evi-

    dence of another motive for earnings manipulation in these ¯rms, namely

    managers' desire to sell overpriced stock and option holdings. While Erickson

    et al. (2006) ¯nd no consistent evidence that the likelihood of fraud in these

    ¯rms is related to managers' equity incentives, Johnson et al. (2009) ¯nd that

    this likelihood is positively related to the size of managers' stockholdings.

    2.1.2. Financial misstatements

    Agrawal and Chadha (2005) ¯nd that the probability of restating earnings is

    lower when boards and audit committees have ¯nancial expertise. Burns and

    2See Agrawal and Chadha (2005: 373–374) for a discussion of their relative seriousness.

  • Kedia (2006) ¯nd that ¯rms whose CEOs have large option holdings are more

    likely to misreport. Top executives also engage in abnormally large amounts

    of stock sales and option exercises during misstated periods (see, Agrawal and

    Cooper, 2015; Burns and Kedia, 2008). Kedia and Philippon (2009) show

    theoretically and empirically that ¯rms hire and invest excessively during

    misreported periods to exaggerate their growth prospects.

    2.1.3. Earnings management

    Prior research ¯nds more earnings management at ¯rms with less indepen-

    dent boards and audit committees (see, Klein, 2002) and in ¯rms where CEO

    compensation is more closely tied to the value of stock and option holdings

    (see, Bergstresser and Philippon, 2006). The latter paper also ¯nds that

    during periods of high accruals, CEOs exercise unusually large amounts of

    stock options, and CEOs and other insiders sell large amounts of stock.

    2.1.4. Corporate fraud and other crimes

    Alexander and Cohen (1999) examine a sample of 78 public companies in-

    volved in corporate crimes such as contract breaches, bribes, kickbacks and

    regulatory violations. They ¯nd lower incidence of crime among ¯rms where

    management owns more equity. Niehaus and Roth (1999) ¯nd no evidence of

    abnormal stock sales by o±cers and directors in a sample of ¯rms that settle

    securities class action lawsuits. Povel et al. (2007) explain theoretically why

    corporate frauds increase in good times, peak toward the end of a boom and

    are revealed in the ensuing bust.

    2.2. Consequences

    2.2.1. SEC and DOJ enforcement actions

    Dechow et al. (1996) ¯nd that ¯rms subject to SEC AAERs (see, Sec. 2.1.1)

    for manipulating earnings experience signi¯cant increases in their costs of

    capital. Beneish (1999) ¯nds no evidence of abnormal management turnover

    in these ¯rms. Chen et al. (2005) present univariate evidence of greater CEO

    and auditor turnover surrounding enforcement actions for securities fraud in

    China. Karpo® et al. (2008a) examine the consequences of ¯nancial misrep-

    resentation to managers of ¯rms subject to SEC and DOJ enforcement

    actions under the Securities Exchange Act of 1934, as amended by the For-

    eign Corrupt Practices Act of 1977. They ¯nd that about 93% of the man-

    agers identi¯ed by regulators as culpable lose their jobs during the violation

  • or enforcement periods; about 28% of them face criminal prosecutions and

    31% are barred from serving as o±cer or director of a public company.3

    Karpo® et al. (2008b) ¯nd that the reputational penalties to companies (i.e.,

    the drop in market capitalization) for ¯nancial misrepresentation far exceed

    the legal penalties (both private and regulatory).

    2.2.2. Financial misstatements

    Desai et al. (2006) examine a sample of 146 ¯rms that announce earnings

    restatements during 1997–1998. They ¯nd that the top management (CEO,

    Chairman and President) of these ¯rms experiences abnormally large turn-

    over and diminished job prospects following restatements. Srinivasan (2005)

    ¯nds that outside directors of restating ¯rms experience abnormally large

    turnover and loss of other board seats. This e®ect is greater for audit com-

    mittee members and for more severe restatements.

    Collins et al. (2009) analyze involuntary CFO turnover following an-

    nouncements of earnings-decreasing restatements made by 167 ¯rms during

    1997–1999 (pre-SOX sample) and 196 ¯rms during 2002–2003 (post-SOX

    sample). They ¯nd that for both pre- and post-SOX restatements, the CFO

    turnover rates in restating ¯rms are higher than those in control samples.

    While the increase in the probability of CFO turnover is similar pre- versus

    post-SOX, CFOs of restating ¯rms are penalized more severely in the labor

    market post-SOX.

    Leonne and Liu (2010) study CEO and CFO turnover in a sample of 96

    ¯rms that reveal accounting irregularities within eight years of their initial

    public o®erings (IPOs), and in a control sample. They ¯nd that after newly

    public ¯rms reveal accounting irregularities, the probability of CEO (CFO)

    3Karpo® et al. assume that regulators know the identities of the individual perpetrators ofeach fraud and argue that event-based studies of executive turnover commit type I and typeII errors. While examining the consequences to managers charged by regulators is obviouslyof interest, the identi¯cation of individual perpetrators by regulators is not foolproof. TheSEC and DOJ have signi¯cant leverage during a formal investigation; they can threaten tocharge the entire company, a step that would seriously hurt the company's viability. Giventheir repeated dealings with regulators, companies have strong incentives to cooperateduring an investigation. A company can help railroad select perpetrators to satisfy reg-ulators and bring quick resolution to an investigation. Often, in an attempt to reduce thelegal-defense resources of identi¯ed perpetrators, regulators demand that the individuals be¯red (see, e.g., Wall Street Journal, 2007). Even if regulators identify the wrong individualsas perpetrators, the company is likely to terminate these individuals because they havebecome \damaged goods".

  • turnover is lower (higher), on average, when CEOs are founders. Within their

    sample of newly public ¯rms that reveal accounting irregularities, they ¯nd

    an average turnover rate for founder (non-founder) CEOs of 29% (49%).

    Huang and Scholz (2012) study auditor resignations during the period 2003–

    2007. They ¯nd that the frequency of auditor resignations is 19% in their

    sample of restating ¯rms compared to 1% in a sample of matched control ¯rms.

    For a sample of 177 Canadian ¯rms that announce restatements during

    the period 1997–2006, Kryzanowski and Zhang (2013) ¯nd that CEO, CFO,

    top executive and auditor turnover rates subsequent to restatement

    announcements are signi¯cantly higher in the sample of restating ¯rms than

    in a control sample.

    We add to the evidence on top management, CFO and auditor turnover by

    examining a larger sample of restatements that are likely more serious. We

    also examine a number of sub-samples where the restatements are likely to

    have greater e®ects.

    2.2.3. Earnings management

    Bradshaw et al. (2001) ¯nd no evidence of greater turnover of auditors fol-

    lowing higher levels of accruals. Hazarika et al. (2012) study CEO turnover

    following earnings management during 1992–2004. They ¯nd that the

    probability of forced CEO turnover is positively related to a ¯rm's absolute

    performance-adjusted discretionary accruals in the previous year. This ¯nd-

    ing persists when they control for restatements and enforcement actions.

    2.2.4. Corporate fraud and other crimes

    Agrawal et al. (1999) examine a sample of ¯rms facing a variety of fraud

    accusations from investors, customers, suppliers, employees or governments,

    regulatory violations, and 12 cases of ¯nancial reporting fraud. They ¯nd

    greater turnover of inside directors, but little systematic evidence of greater

    turnover of top managers and outside directors, following fraud revelations.

    Niehaus and Roth (1999) ¯nd abnormally high CEO turnover in a sample of

    ¯rms that settle securities class action lawsuits, especially in suits with more

    merit. Helland (2006) ¯nds that directors of ¯rms facing such lawsuits do

    not su®er a net loss of their board seats, except for cases in the top quartile

    of settlements or where the SEC initiates a case. Fich and Shivdasani (2007)

    ¯nd no evidence of abnormal turnover of outside directors in ¯rms facing such

    lawsuits, but ¯nd a signi¯cant decline in their other board seats.

  • 3. Sample and Data

    Section 3.1 details our sample selection procedure and describes the sample of

    restating ¯rms. Section 3.2 deals with the selection of our control sample and

    compares the restating and control samples. Section 3.3 describes the stock

    price reaction to the restatement announcements, and Sec. 3.4 examines the

    operating performance of the two samples.

    3.1. Sample of restating ¯rms

    Our sample of restating ¯rms is obtained from the United States General

    Accounting O±ce (GAO, 2002), which lists 919 restatements of ¯nancial

    statements announced by 832 publicly traded ¯rms during the period Jan-

    uary 1, 1997 to June 30, 2002. These restatements correct prior misstate-

    ments, i.e., violations of generally accepted accounting principles (GAAP).

    Most of the restatements correct quarterly or annual ¯nancial statements

    ¯led with the SEC.4 The GAO database excludes routine or technical

    restatements prompted by mergers and acquisitions, discontinued operations,

    stock splits, accounting rule changes, and changes in accounting method. We

    consider the seriousness of restatements in our sample in Sec. 5.1 below.

    Table 1 summarizes our sample selection procedure. Starting with the

    919 restatements in the GAO database, we omit 87 cases of repeat restate-

    ments by sample ¯rms.5 In order to obtain a control sample and to construct

    several control variables (see, Sec. 3.2 and 4.2 below), we require that a

    restating ¯rm be listed on the Center for Research in Security Prices (CRSP)

    database of the University of Chicago starting at least nine months before the

    restatement announcement. We also require sample ¯rms to have at least

    two-thirds of the daily stock returns available over the one-year period prior

    to the announcement date. A total of 88 (¼ 47þ 13þ 5þ 23) ¯rms do notsatisfy these requirements. We omit an additional 62 cases where the

    restating ¯rm is a real estate investment trust, exchange-traded fund, or is

    incorporated outside of the U.S. We also omit two cases where our review of

    4Fifteen cases in our sample are restatements of earnings releases and do not result in re-statement of quarterly or annual ¯nancial statements. Omitting these cases does not changeany of our results.5Our ¯nal sample of 518 restating ¯rms includes 50 ¯rms that announced multiple restate-ments during the sample period. Second and subsequent restatements by these 50 ¯rms are notincluded in our sample. Furthermore, our results are qualitatively similar when we omit these50 repeat violators from the sample.

  • news reports and SEC ¯lings indicates that a misstatement did not occur.

    Finally, we omit 162 cases where the restatement did not decrease net income

    because auditors and investors appear to view such restatements as less se-

    rious (see, e.g., Agrawal and Chadha, 2005).6 Our ¯nal sample consists of 518

    ¯rms that announce earnings-decreasing restatements.7,8 For each restate-

    ment in our sample, we collect data on the original earnings, restated earn-

    ings, and the quarters restated by reading news reports and the original and

    Table 1. Sample selection.

    Note: The table shows sample selection out of the 919 restatements listed inFinancial Statement Restatements: Trends, Market Impacts, RegulatoryResponses, and Remaining Challenges (Washington, D.C.: GAO-03-138), adatabase of restatements, announced during the period January 1, 1997 to June30, 2002, to correct GAAP violations.

    6Consistent with this idea, the stock price reaction to such announcements, although statis-tically signi¯cant, is much smaller than to earnings-decreasing restatements. Over the windowof days (�1, þ1) around the announcement, the average cumulative abnormal return (CAR)for the two samples is �3.3% and �10.3%, respectively; the corresponding values over the(–20, þ1) window are �6.6% and �17.7%. Nevertheless, for completeness, we separatelyanalyze the sample of non-earnings-decreasing restatements. We ¯nd marginally signi¯cantevidence of greater CEO turnover in these ¯rms, but no evidence of greater turnover amongtop management, CFOs, top ¯nancial managers, or outside auditors. To save space, we do notpresent these results in a table.7Our sample includes 16 ¯rms that dissolved or terminated their registration with the SECafter the announcement but before any restatement.8In a few instances, a ¯rm listed in the GAO database restated its ¯nancial statements becausethe ¯nancial statements of a newly acquired subsidiary were misstated for ¯scal years orquarters ending prior to the acquisition date. In such cases, we replace the acquiring ¯rm withthe subsidiary.

  • amending 10-Qs and 10-Ks ¯led with the SEC.9,10 We obtain news reports

    from the ProQuest newspapers database, Lexis–Nexis news wires database,

    and press releases attached to 8-Ks ¯led with the SEC. Finally, we obtain

    stock prices and returns from CRSP and ¯nancial data from Compustat.

    Table 2 describes our sample of 518 restating ¯rms. Panel A summarizes

    the distribution of our sample by the identity of the initiator and by the

    nature of accounts restated. About 79% of the restatements in our sample are

    initiated by the company itself,11 and about 7% by the outside auditor. Most

    of the remaining restatements are initiated by the SEC. About 63% of the

    cases involve only core accounts, about 16% involve only non-core accounts,

    and the remaining cases involve both.12

    Panel B provides descriptive statistics of ¯rm age and the magnitude of the

    change in earnings due to restatement. The median ¯rm has been listed on

    CRSP (i.e., on NYSE, AMEX or Nasdaq) for about 6.5 years. The median

    change in earnings13 is about �33%. The mean change is much larger, about�234%. The median ¯rm restated four quarters of earnings, and the medianlength of the misstated period is 586 days.

    Panel C of Table 2 shows the distribution of the number of quarters

    restated. About 20% of the sample ¯rms restate a single quarter's ¯nancial

    statements (not tabulated). About 55% of the ¯rms restate four or fewer

    quarters, 19% restate ¯ve to eight quarters and the remaining 26% restate

    nine or more quarters. Approximately 3% of the sample ¯rms restate more

    than 20 quarters.

    9In several instances, news reports and SEC ¯lings indicate that the restatement was an-nounced before the announcement date listed in the GAO database. Because we use the earlierannouncement date in such cases, eight ¯rms in our sample have announcement dates prior toJanuary 1, 1997, the beginning date of the GAO database.10 In determining the beginning date of the misstated period, we take into account anyadjustments made to retained earnings for prior periods. In addition, if a ¯rm restates its¯nancials for, say, the ¯scal year ending December 2000, but the amended 10-K indicates thatthe restatement relates only to the last two quarters of the year, we de¯ne the beginning dateof the misstatement as July 1, 2000.11Following Palmrose et al. (2004), this category includes cases where the identity of theinitiator is not identi¯ed in the GAO database.12We classify as core restatements cases involving routine accounts such as sales revenue, costof sales, selling, general and administrative expenses, accounts receivable, inventory, accountspayable, and certain accrued liabilities (e.g., accrued workers' compensation expense). Weclassify cases involving non-routine accounts and one-time or special items as non-corerestatements. For restatements that a®ect income statement accounts, our de¯nition of corerestatements is very similar to that of Palmrose et al. (2004).13Change in earnings is de¯ned as (Restated earnings-Original earnings) / jOriginal earnings j.

  • Panel D shows the industry distribution of the sample based on the ¯rst

    two digits of a ¯rm's primary SIC code, using Song and Walkling's (1993)

    industry classi¯cation. For comparison, we also show the corresponding

    distribution for the active CRSP population as of December 31, 2002. Of our

    sample of 518 restating ¯rms (CRSP population), 26% (20%) are in services;

    15% (13%) in machinery; 12% (20%) in ¯nance, insurance and real estate; 8%

    (7%) in transport, communications and utilities; 7% (7%) in chemical in-

    dustry; and 7% (6%) in retail trade. The remaining 25% (27%) of the ¯rms

    are distributed over 12 (14) di®erent industries.

    Panel E of Table 2 shows the distribution of the sample by the year of

    restatement announcement. There is a sharp increase in the number of

    restatements announced starting in 1999. The data for 2002 is for the ¯rst

    half of the year. About 41% of the restatements in the sample were an-

    nounced during 1996–1999, and the remaining 59% were announced during

    2000–2002.

    3.2. Control sample

    We compare management and auditor turnover in restating ¯rms to that in a

    control group. The restating and control ¯rms are matched by size and in-

    dustry one year before the announcement date.14 We match each restating

    ¯rm with a control ¯rm that has the same two-digit primary SIC industry

    code, is the closest in size, and did not announce a restatement during the

    period January 1, 1995 to June 30, 2002. Size is de¯ned as the market cap-

    italization of common stockholders' equity and equals the number of common

    shares outstanding times the closing share price reported by CRSP on the

    matching date.15 The pool of potential matching control ¯rms excludes ¯rms

    incorporated outside of the U.S. Each control ¯rm is matched to a single

    restating ¯rm.

    Panel A of Table 3 shows characteristics of our samples of restating and

    control ¯rms. All dollar values reported in the paper are in in°ation-adjusted

    2005 dollars. All variables in Table 3 are measured for the last ¯scal year

    ending before the restatement announcement date. The typical restating ¯rm

    in our sample is relatively small compared to the typical ¯rm traded on the

    14Some restating ¯rms were not listed in CRSP one year prior to the announcement date. Forthese ¯rms, the matching date is the restating ¯rm's ¯rst trading day in CRSP. We excluderestating ¯rms whose beginning date in CRSP is less than nine months before the an-nouncement date.15All publicly traded common share classes are included when calculating market capitali-zation.

  • major U.S. stock markets. For the sample of restating (control) ¯rms, the

    median values of total assets, net sales and number of employees are about

    $236 million ($243 million), $153 million ($173 million) and 900 (1,000)

    people, respectively.

    The two groups of ¯rms appear to have similar growth opportunities, as

    measured by the ratio of ¯rm value to total assets and the ¯ve-year sales

    growth rate.16 The two groups also have similar ¯nancial leverage ratios. For

    example, the median ratio of long-term debt to ¯rm value for each group is

    about 7%.

    Panel B of Table 3 shows certain board characteristics observed one year

    before the year of announcement using the S&P Register of Corporations,

    Directors and Executives. The median board consists of seven members,

    about 71% of whom are outsiders in each group of ¯rms. About 65% (62%) of

    the CEOs of restating (control) ¯rms chair the board.

    3.3. Stock price reaction

    We next examine the stock price reaction to restatement announcements. We

    compute the abnormal return for stock i on day t as:

    eit ¼ rit � rmt; ð1Þwhere ri and rm are the stock returns for ¯rm i and the market, respectively.

    The market return is de¯ned as the return on the CRSP (i.e., NYSE, AMEX

    and Nasdaq) equal-weighted stock index. The cumulative abnormal return

    (CAR) for ¯rm i over days (t1, t2Þ is measured as:

    CARit1;t2 ¼Xt2

    t¼t1eit : ð2Þ

    Table 4 shows the mean and median values of CARs for our full sample of

    restating ¯rms and for a number of sub-samples over ¯ve windows covering

    trading days (�1;þ1), (�5;þ1), (�5;þ5), (�20;þ1) and (�20;þ20) aroundthe announcement date (day 0). Restatement announcements have large

    e®ects on stock prices. The mean CAR for restating ¯rms ranges from

    �10.3% over days (�1;þ1) to as much as �20:9% over days (�20;þ20).Mean and median CARs for all ¯ve windows are signi¯cantly di®erent from

    zero at the 1% level. The announcement e®ects are even more negative for the

    sub-samples of more serious restatements (discussed in Sec. 5.1 below), cases

    16Firm value is de¯ned as the book value of total assets minus the book value of equity plus themarket value of equity.

  • where the restated earnings are negative, cases where the restatement leads

    to a large drop in reported earnings (large restatements) and cases with more

    restated quarters. For comparison, the abnormal returns for non-restating

    ¯rms (not shown in the table) are small and statistically insigni¯cant over all

    ¯ve windows.

  • 3.4. Operating performance

    We next examine the operating performance of our samples of restating and

    control ¯rms over the years (�3;þ3), where 0 is the ¯scal year that endsclosest to the restatement announcement date. We use two measures: oper-

    ating performance to assets (OPA) and operating performance to sales

    (OPS). OPA (OPS) equals operating income before depreciation as a per-

    centage of a ¯rm's total assets (net sales). We compute average OPA or OPS

    values over multiple years by summing a ¯rm's ratios over the relevant years

    and averaging these sums across ¯rms. Table 5 shows that the median OPA

    and OPS for the two groups of ¯rms are statistically indistinguishable in year

    �3. Starting in year �2 (–1), the OPA (OPS) for the median restating ¯rm islower than that for its control ¯rm.17 This pattern persists until year þ2.

The restatement sample con-sists of 518 publicly traded U.S. ¯rms that announced earnings-decreasing restatements duringthe period January 1, 1997 to June 30, 2002, as identi¯ed by the GAO Report. Each restating¯rm is matched with a control ¯rm that has the same two-digit SIC code and closest marketvalue of equity one year before the restating ¯rm's announcement date. The control ¯rms didnot announce restatements during the period January 1, 1995 to June 30, 2002. A sample¯rm's OPA (OPS) equals operating income before depreciation as a percentage of the ¯rm'stotal assets (net sales). OPA and OPS are calculated for seven ¯scal years beginning three¯scal years before the announcement year and ending three ¯scal years subsequent to theannouncement year. Each ¯rm's OPA or OPS percentages are summed over the applicableyears to calculate median values for multiple-year periods. P-values are for matched-pairst-tests (two-tailed) for di®erences in means or Wilcoxon signed-ranks tests (two-tailed) fordi®erences in medians.

    17Young technology ¯rms with sizeable losses and minimal revenues cause mean OPS valuesto be very negative in some years.

  • For example, the median OPA in year 0 for restating (control) ¯rms is 4.5%

    (9.7%). These di®erences are both statistically and economically signi¯cant.

    4. Management and Auditor Turnover: Full Sample Results

    We discuss univariate results on management and auditor turnover in

    Sec. 4.1, correlations between the variables in Sec. 4.2, and results of the

    logistic regressions in Sec. 4.3.

    4.1. Univariate results

    Table 6 presents mean turnover rates and the percentage of ¯rms with turn-

    over of management and outside auditor. The ¯rst two columns show mean

    turnover rates for CEOs in matched samples of restating (R) and control (C)

    ¯rms. The next two columns report two-tailed p-values from matched pairs

    t-tests for di®erences in means andWilcoxon signed-ranks tests for di®erences

    in medians. Column 5 shows sample size. The next four sets of ¯ve columns

    each show corresponding values for top management (CEO, Chairman, and

    President), CFO, top ¯nancial o±cers (CFO, Controller and Treasurer), and

    outside auditor. For a given year, turnover for a ¯rm equals 1 if the group of

    o±cers or auditor listed in the S&P Register di®ers from the previous year's

    listing; it equals 0 otherwise.18 The table shows turnover for years �1 to þ2,where 0 is the year of announcement. Turnover values for individual years are

    summed to compute turnover for multi-year periods. P-values are computed

    from two-tailed matched pairs t-tests for di®erences in means and Wilcoxon

    signed-ranks tests for di®erences in medians.

    Table 6 shows signi¯cantly greater turnover of CEOs, top management

    and CFOs of restating ¯rms relative to control ¯rms in each of years 0

    through þ2 and for all ¯ve multi-year periods. The magnitudes of thesedi®erences are substantial. For example, in year 0, the CEO (CFO) turnover

    in restating ¯rms is 20% (27%); the corresponding rate for control ¯rms is

    only 9% (11%). Over the window of years (�1;þ1), the CEO (CFO) turnoverrate in restating ¯rms is 53% (65%), while the rate for control ¯rms is only

    34% (43%). There is also evidence of abnormally large turnover for the group

    of top ¯nancial o±cers in restating ¯rms in years þ1, (0;þ1) and (þ1;þ2).

    18In cases where a ¯rm listed in the S&P Register in the prior year is not listed in the currentyear, we attempt to identify the reason for the non-listing (e.g., name change, merger, pri-vatization, or bankruptcy) using the listings under \additional companies formerly included"in the S&P Register and by consulting the Directory of Obsolete Securities.

  • The table also shows abnormally large turnover rates for the outside auditors

    of restating ¯rms in year þ1 and in several multi-year periods.

    4.2. Correlations

    We next examine Pearson correlation coe±cients (not tabulated for brevity)

    for management and auditor turnover and explanatory variables. RESTATE

    is a dummy variable equal to 1 if the ¯rm is a restating ¯rm; it equals 0

    otherwise. LSALES is the natural logarithm of net sales. V/A equals ¯rm

    value divided by total assets. D/A equals total debt divided by total assets.

    OUTSIDER equals the number of outside directors divided by board size.

    BOSS equals 1 if the CEO chairs the board; it equals 0 otherwise. Data

    availability reduces the sample size to 600 ¯rms (i.e., 300 matched pairs).

    We ¯nd several noteworthy relations. First, consistent with the univariate

    results in Table 6, the turnover of CEOs, top management and CFOs over

    several time windows is positively related to the RESTATE variable. Second,

    CEO and top management turnover are lower when the CEO chairs the

    board. This is not surprising, given that a CEO-Chairman wields more power.

    Third, the turnover of CFOs is positively related to the turnover of both

    CEOs and auditors. The positive correlation between CFO and CEO turn-

    over is consistent with Mian (2001). The positive correlation between the

    turnover of CFOs and auditors suggests that their fortunes are linked in the

    aftermath of a restatement. Fourth, larger ¯rms (LSALES) have higher debt

    ratios (D/A), consistent with higher debt capacity and greater access to

    public debt markets. Finally, larger ¯rms have larger boards, with a higher

    proportion of outside directors. The positive relation between ¯rm size and

    board size is consistent with the notion that larger ¯rms are more complex

    and so need more expertise on the board, requiring more board members (see,

    e.g., Agrawal and Knoeber, 1996). The positive relation between ¯rm size and

    the proportion of outsiders on the board is consistent with the greater pres-

    sure during our sample period on large public ¯rms to have more independent

    boards (see, e.g., NYSE and Nasdaq, 1999). All of these relations are sta-

    tistically signi¯cant at the 5% level in two-tailed tests.

    4.3. Cross-sectional regressions

    We next examine whether management and auditor turnover following the

    revelation of accounting problems is higher than control ¯rms, after con-

    trolling for other determinants of the level of turnover. We discuss the
