1. Introduction
The importance of corporate social responsibility (hereafter, “CSR”) to the survival of businesses has culminated in an increase in the number of firms now committing enormous resources, and in the quantity of resources committed by these firms to CSR activities. Consumers expect companies to integrate activities that will improve society and the environment with their business objectives (
Brînzea et al. 2014). Anecdotal evidence suggests that 90% of Americans are less likely to purchase products from companies that are not socially responsible. Thus, the role of CSR in ensuring the long-term survival of companies cannot be over-emphasized. Additionally, the Organization for Economic Co-operation and Development, the United Nations (UN), and the European Union (EU) have all emphasized the immense importance of CSR activities to organizations (
Grimstad et al. 2020). However, CSR activities introduce complexity into the firm’s financial reporting (
Hickman et al. 2020) and could delay the release of audited financial statements. Audit report lag is significant to investors as it directly impacts decision-making and investment fortunes (
Bartov and Konchitchki 2017). Agency theory suggests that managers could capitalize on the importance of CSR activities and engage in actions that will increase the organization’s risk level (
Masulis and Reza 2015).
The motivation of this study is the increased demand for companies to engage in socially and environmentally responsible activities while also increasing the bottom line, although there is a tendency for these activities to introduce complexities into the firm’s financial reporting and extend the completion of the audit. Additionally, many researchers, policymakers, and corporate directors question the impact that CSR activities are having or may have on organizations and their stakeholders.
The literature suggests that there is no consensus on the impact of CSR activities on organizations and their stakeholders. While one school of thought believes that CSR activities are beneficial to organizations and financial information users (
Ferrell et al. 2016), others believe that CSR activities may be detrimental to organizations and their stakeholders (
Garcia et al. 2020). Prior studies have examined the factors that influence the delay in the release of audited financial statements. Determinants of audit report lag studied by Habib et al. 2019 found that, amongst others, audit report lag is significantly and positively impacted by the complexity of the firm, the firm’s risk exposure, and the internal controls employed by the firm.
Habib et al. (
2019) noted that audit report lag is inversely related to board independence and firm profitability. Researchers are also divided on the relationship between audit fees and audit report lag (
Garcia et al. 2020;
Carey et al. 2017). Some researchers contend that the complexity of CSR activities introduces complexities and risks to the firm’s financial reporting and increases the time and effort required by the auditor to complete the audit. The extended time culminates in an increase in the fees charged by the auditor. However, other researchers contend that the audit fees charged do not necessarily imply that audit report lag will be impacted.
Thus, the objective of this study was to examine the impact of CSR on the timeliness of audited financial statements. We contend that if CSR introduces complexity into the firms’ financial reporting and increases the auditors’ risk exposure, then it is likely that auditors will spend more time and effort to mitigate the propensity for material misstatements. Thus, the audit report lag will be extended. Additionally, auditor risk exposure increases in firms with unethical management and could culminate in extended audit report lags as well.
Studies reveal that companies are redirecting their attention to include more social and environmental activities (i.e., green innovation practice and the United Nation’s (UN’s) 2030 sustainable development goals (SDGs)) in their strategic decision-making to, amongst others, satisfy the needs of the investing public, boost their image, and enhance reported financial performance (
Ali et al. 2022;
Khan et al. 2021a,
2022). For example,
Khan et al. (
2021a) provide empirical evidence that firms that adopt green product innovation tend to achieve better financial performance such as returns on equity (ROE). Furthermore, in recent years, larger firms are incorporating the UN’s 2030 SDGs in their business models, implying that the firms attempt to utilize them as their strategic mechanism for implementing their CSR initiative (
Santos and Bastos 2020). A recent study by
Khan et al. (
2022) empirically examines the impacts of firms’ implementation of the UN’s 2030 SDGs on their firm’s performance and documents that the environmental (social) SDGs exhibit a positive (negative) relation with firms’ financial performance.
This reaction of firms to CSR activities can be viewed from the perspective of the legitimacy theory within the social and accounting literature. The legitimacy theory suggests that a firm’s quest for survival compels it to make every effort to engage in activities that demonstrate its utmost desire to deal with societal and environmental issues (
Olateju et al. 2021). Consistent with the legitimacy theory, firms often discretionarily report their CSR activities utilizing various voluntary or mandatory channels to ensure that the public is aware of their environmental and societal contributions. Indeed,
Cong et al. (
2020) provided evidence that firms attempt to legitimize their greenhouse gas emissions via climate-related disclosures.
KPMG (
2020) reports that 80% of the 5200 companies sampled worldwide are now reporting on sustainability
1. The same report claims that, in North America, 90% of the companies provide sustainability reports. In addition, the number of firms reporting under the Global Reporting Initiative has skyrocketed. The number of reporting firms increased from 48 in the year 2000 to more than 14,750 in the year 2020 (
Global Reporting Initiative 2020).
The News media is now providing extensive support in disseminating CSR activities due to the immense public interest (
Lee and Carroll 2011;
Huang and Watson 2015). The positive publicity that organizations stand to derive from engaging in CSR activities engenders top management to place significant emphasis on CSR activities.
Asongu (
2007) contends that CSR activities are investments (not expenses) that have enormous potential benefits to organizations. Considering the quantity of resources that organizations currently employ and the emphasis that organizations now place on CSR activities, it is conceivable that the organizations’ CSR activities may influence their control environment as it relates to management’s philosophy, operating style, and ethical values, to name but a few. The tone at the top concerning CSR activities could have significant ramifications on the organizations’ risk levels, including but not limited to, class action lawsuits against the firms for possible social and environmental infractions.
We discuss the relationship between accounting for climate change and audit risk and environment and audit risk together.
Ngwakwe (
2012) argues that accounting for climate change focuses on greenhouse gas (GHG) footprints, carbon emissions, carbon capture and storage, and appropriations calculations. Similarly,
Brown et al. (
2009) posit that accounting for climate change comprises a myriad of elements, including climate change performance, environmental audits, and sustainability. All these elements involved in environmental accounting present significant accounting issues. The absence of formal accounting standards results in a lack of trust and uncertainty in climate change accounting (
Gulluscio et al. 2020).
Milne and Grubnic (
2011) found that accounting for GHG and carbon presents immense challenges due to the ambiguity in estimation methods. These challenges inject complexities and risks that translate into high audit risk.
Asare et al. (
2002) suggested that organizations with weak governance represent high audit risk and pay high audit fees. The high audit risk and fees translate to extensive audit effort. We interchange corporate charitable contributions with philanthropy in our paper. The literature posits that various factors may influence corporate charitable contributions. The altruistic theory suggests that organizations will make charitable contributions because they truly care about the cause to which they donate (
Choi and Wang 2007). The social pressure theory suggests that organizations may also contribute to certain causes because they do not want to deal with the pressure that will be directed their way, as they are perceived as unconcerned about a cause that appears to be dominant in society. Agency theory argues that managers may abuse corporate charitable contributions to enhance their own wealth due to managerial opportunism, potentially increasing the organizations’ risk level and eroding future firm gains (
Masulis and Reza 2015). The literature claims that 62% of organizations give charitable contributions to charities associated with their CEOs (
Masulis and Reza 2015). The legitimacy theory suggests that organizations will make charitable contributions to compensate for bad news (
Ashforth and Gibbs 1990). Thus, it appears that corporate philanthropy is only a means for organizations to satisfy their parochial interests. Therefore, these organizations may be willing to engage in illegal acts that auditors will expend significant energy and time to avoid audit failure. Hence, the auditors assess high audit risk. These arguments are also in line with how organizations approach human rights.
Employee relation is a critical factor that directly impacts the financial performance of organizations. Employees with specialized skills have continued investments in their organizations (
Maltby and Wilkinson 1998). Employees are also financially dependent on their organizations.
Cavanaugh and Noe (
1999) argue that current employment practices are based on personal responsibility for career development, commitment to a particular kind of work rather than a particular employer, and an expectation of job insecurity. These factors place the employees firmly in charge of their professional growth development. Considering that employees now emphasize their work rather than the employer and expect job insecurity, accounting for employee relations could present potential accounting challenges, especially because of turnovers. Such turnovers can potentially increase audit risk since auditors will see a lack of continuity and a longer learning curve for new employees, leading auditors to spend more time auditing the financial statements. Tournament theory also suggests that senior employees (managers) engage in silent tournaments to prove who is more suitable to become the next CEO of the organization (
Bryan and Mason 2017). The literature argues that these managers may engage in behaviors that impact the organization’s financial statement. These behaviors may force auditors to assess a high risk of material misstatements and therefore expend more effort and time auditing the organization’s financial statements.
CSR activities may potentially result in legal concerns and environmental liabilities that may translate into accounting and financial reporting complexities for companies (
Garcia et al. 2020).
Garcia et al. (
2020) note that CSR performance injects complexity into audits.
Hickman et al. (
2020) suggest that CSR activities may influence accounting judgments and decisions, resulting in inaccurate accounting estimates and adjustments such as allowance for bad debts, among others.
The research suggests that organizations’ CSR activities influence auditors’ assessment of the risk levels and the audit fee (
Chen et al. 2011;
Leventis et al. 2013;
Koh and Tong 2013).
Hickman et al. (
2020) argued a relationship exists between firms’ CSR performance and auditor risk assessment. Given that CSR activities inject complexities into audits, which is likely to impact the auditors’ risk assessment, we conjecture that CSR activities might cause the auditors to assess high audit and business risks.
The high audit and business risks could include both reputational and potential litigation risks. When auditors assess high audit risk, they are inclined to perform extended procedures and expend more effort that can extend the audit completion time.
The empirical question to which this study finds answers is whether CSR activities will culminate in the delay of audited financial statements. This study explores the association between CSR activities and the time an auditor spends completing the audit. Therefore, we investigate the relationship between CSR activities and audit report lag. We contend that if CSR activities inject complexity into the audit, we expect that it will take the auditor longer to complete the audit, making the financial information less timely.
The timeliness of financial information is critical to its relevance.
Atiase et al. (
1989) argued that financial information loses its relevance when it is delayed. A key determinant of the timeliness of financial information is how long it takes the auditor to complete the audit (
Knechel and Sharma 2012). This duration is referred to as the audit report lag. The audit report lag is defined as the time between a firm’s fiscal year-end and the audit report date (
Lamptey et al. 2021;
Bryan and Mason 2020). We measured CSR activities using a composite binary variable,
CSR_100, representing a firm’s inclusion on or exclusion from the annual list of “100 Best Corporate Citizens” issued by 3BL Media. According to 3BL Media, the list is prepared based on the evaluation of six CSR components and one financial component. The six CSR components include environment, climate change, human rights, employee relations, governance, and philanthropy. Considering that the primary evaluation sources used by 3BL Media in generating the
CSR_100 firms are those firms’ CSR performance and disclosure, we considered a firm’s inclusion on the list as a consequence of its substantially high level of CSR activities.
To examine the association between CSR activities measured by CSR_100 and audit report lag, we used robust regression analyses and found a strong positive and significant relation between CSR_100 and audit report lag after controlling for other variables affecting audit report lag. Furthermore, we examined whether there is an association between the timeliness of financial information and each of the six components of CSR_100. We found a positive and significant association between audit report lag and the environment, climate change, human rights, employee relations, and philanthropy. However, our result did not show a significant association between audit report lag and governance.
Our study makes a significant contribution to the CSR and audit literature by examining the potential effect of an organization’s proactive CSR activities on their audit risk, business risk, and managerial ethical behavior. Numerous prior studies have explored potential factors that significantly influence business complexity and audit risk, but our study concentrated on an organization‘s CSR activities as a new driver of audit risk. Another important contribution of our study is that our study introduces and seriously discusses a relatively new and adverse feature of an organization’s CSR initiatives and activities. That is, our study revealed that, although CSR activities can ultimately enhance reported performance, unethical behavior of the managers and the complexity introduced by CSR activities can introduce risks with adverse consequences to firms. Stakeholders expect socially responsible firms to exhibit high ethical behavior (
Gelb and Strawser 2001;
Lee 2017). However, agency theory suggests that managers have the propensity to engage in activities that are inimical to the interest of the stakeholders. Thus, managers could be inclined to engage in CSR activities to mislead stakeholders (
Ben-Amar and Belgacem 2018;
Jensen 2001).
Although many researchers have explored the influence of CSR activities on financial performance, our comprehensive literature review shows a gap in the literature about the impact of complexities introduced by CSR activities on financial reporting and the audit process. Specifically, extant literature does not show empirical evidence to accentuate the association between the composite CSR_100 and the timeliness of financial information. Neither does it provide support for the relationship between CSR activities and audit report lag. Additionally, to the best of our knowledge, we are not aware of any research that examines the relationship between the top 100 best CSR performers and others and audit report lag using either the composite CSR_100 or the components of CSR_100. Therefore, our study fills this gap by providing empirical evidence to support these relationships.
The finding provides important implications for various audiences (i.e., company managers, investors, auditors, and policymakers) in that a company’s proactive CSR activities would accelerate business complexity, which in turn could lead to an increase in audit risk and audit report lag. In particular, our study offers important insights to policymakers that more standardized and consistent reporting and auditing standards concerning CSR activities need to be established and implemented. We note that, while CSR activities have the potential to increase a firm’s return on investment, any delay in the release of the financial statements is likely to have adverse consequences on investor decision-making. We adopted a firm’s inclusion in the “100 Best Corporate Citizens” list as an empirical proxy to represent CSR activities. Our findings should be important to researchers, policymakers, and auditors as they consider the effect of CSR activities on organizations and stakeholders.
The remainder of our study is organized as follows.
Section 2 provides the literature review and develops the hypotheses. We discuss our research method in
Section 3. We provide the empirical analyses and discussion of our results in
Section 4. In
Section 5, we draw our conclusions and articulate the implications of the study.
Section 6 discusses the limitations of our study and suggestions for future research.
2. Literature Review and Hypothesis Development
CSR activities have the propensity to be either beneficial or inimical to firms and their stakeholders. While
Ferrell et al. (
2016) found that CSR activities are more likely to culminate in high investor returns in firms with fewer agency problems,
Garcia et al. (
2020) found that CSR activities may potentially result in legal concerns and environmental liabilities. CSR activities may translate into accounting and financial reporting complexities for companies.
The time it takes the auditor to complete the audit is critical to investors, as any delays could impact their decision-making. Copious studies ascertain the factors that impact the timeliness of financial statements. The literature documents the determinants of audit report lag (
Leventis et al. 2005;
Abernathy et al. 2017;
Habib et al. 2019).
Habib et al. (
2019) found that audit report lag is significantly and positively related to firm complexity, firm risk, audit fees, and internal control weakness and negatively related to board independence and firm profitability.
Abernathy et al. (
2017) found that audit report lag is longer for firms with weaknesses in their internal control, poor financial performance, and high industry risk and shorter for firms with robust corporate governance mechanisms.
Sultana et al. (
2015) found that audit report lag is shortened when firms have independent audit committee members.
Lamptey et al. (
2021) found that managerial entrenchment shortens audit report lag. They suggested that entrenched managers are more likely to behave ethically.
Leventis et al. (
2005) found that the existence of extraordinary items extends the audit report lag.
Asante-Appiah (
2020) found that while reputational damages arising from environmental and governance practices increase audit report lag, reputational damage arising from social practices does not increase audit report lag as auditors tend to discount the risk.
The literature suggests that researchers are divided on the relationship between audit fees and audit report lag. Whereas researchers like
Chan et al. (
1993) and
Knechel and Payne (
2001) found that higher audit fees may lead to longer audit report lag, others including
Carcello et al. (
1992) and
Leventis et al. (
2005) documented that audit fees may not lead to longer audit report lag. The proponents of the positive association between audit fees and audit report lag contend that CSR-related activities engender audit complexity that requires the auditor to expend a considerable amount of effort to complete the audit, thereby culminating in high audit fees (
Garcia et al. 2020;
Koh and Tong 2013;
Chen et al. 2016;
Carey et al. 2017;
Garcia et al. 2020;
Saeed et al. 2020).
Koh and Tong (
2013) attributed the positive association between audit fees and audit report lag to the business risks associated with clients’ engagement in controversial CSR activities. Studies revealed that the auditor’s failure to deal with the risks effectively could expose the auditor to high potential legal liability (
Simunic 1980;
Scism 1995;
Hays 2004;
Barbaro 2006;
Koh and Tong 2013). The auditor is therefore compelled to expend additional effort to avoid audit failure.
Leventis et al. (
2005) found that the type of auditor appointed impacts the timeliness of the financial statements.
Studies found a positive relationship between financial statement complexity and audit fees. CSR-related activities engender financial statement complexity, increase the audit effort, and impact the fees charged by the auditors.
Hoitash and Hoitash (
2018) found a positive association between the complexity of accounting reporting and the propensity for financial statements to be misstated. They argued that financial reporting requires adequate knowledge of the applicable accounting standards to properly disclose the accounting items. Thus, the more complex the reporting requirements of the firm, the greater the chances that the financial statements will be prone to errors and the audit report extensively delayed.
Managers of firms with weak internal controls often engage in opportunistic behaviors, including, but not limited to, manipulating earnings to enhance reported income. Thus, management introduces a colossal risk to auditors and could impact the timely release of financial statements. While
Chih et al. (
2008) documented that CSR firms are more likely to manipulate earnings.
Shleifer (
2004) found that firms with good CSR reputations are less likely to manipulate earnings.
Considering that CSR activities increase audit complexity and require the auditor to expend a lot of audit effort to ensure that the financial statements are free from material misstatements, we contend that the auditor will likely increase audit efforts to mitigate the audit risk (
Simunic 1980;
Koh and Tong 2013). Consequently, we expect a positive association between the composite CSR activities and audit report lag. We state our first hypothesis as follows:
H1. Ceteris paribus, there is a positive association between the composite CSR activities and audit report lag.
The legitimacy theory and the political cost theory underscore the investments that organizations make and the benefits that those organizations expect from such investments. Consistent with the legitimacy theory, organizations being aware that society expects them to invest some of their profits in their communities, will spend some of their resources protecting the environment and supporting the communities (
Blasio 2007;
Cashore et al. 2003), and obtain even greater publicity for their efforts.
The political cost theory, as it relates to CSR, is the deliberate organizational strategy to invest some of their resources in various CSR activities in conjunction with the government to gain the leverage to influence legislation or regulations at some point (
Halme 2002;
Ruihua and Bansal 2003). Organizations do this to avoid political scrutiny that can hurt their operations.
The legitimacy theory and the political cost theories underscore the behavior of organizations as they include CSR activities in their strategic plans and ensure that investments in such activities are brought to the attention of stakeholders and the public to influence the relationship between the organization and the public. However, investments in these various CSR activities, including those that constitute
CSR_100 (environment, climate change, human rights, employee relations, governance, and philanthropy), potentially introduce accounting and legal concerns for the organizations. Even when the organizations properly record these transactions, there may be inherent and control risks that constitute the risk of material misstatement associated with these transactions. Investing in CSR activities with the associated risks injects complexities into the audits.
Hay (
2013) found a significant positive association between firm complexity and audit fees.
However, each component of CSR activities might require varying amounts of firm resources and efforts, leading to different levels of audit complexity. Thus, it is an empirical question of how significantly each component of CSR activities affects audit report lag. To address this question, we test the association between the components of CSR activities and audit report lag.
Furthermore, the composite CSR performance is an aggregate assessment outcome based on the evaluation of all the CSR components. Hence, we cannot guarantee that the firms with overall good CSR reputations necessarily achieve superior performance in each of all the CSR components. Therefore, we hypothesized, in an alternative form, that:
H2. Ceteris paribus, there is a positive association between CSR components and audit report lag.
3. Research Design and Methodology
3.1. Data and Sample Description
Our sample comprised 3661 firm-year observations and 776 firms from 2011 to 2016
2. We believe our sample period could completely avoid all potential effects of the global COVID-19 pandemic on socio-economic circumstances (including auditing practice) during the COVID-19 era. Thus, we expect that our results could be applicable to the upcoming post-COVID-19 periods. We obtained the data for CSR_100 from the annual list of “100 Best Corporate Citizens”, which is available on the website of 3BL Media (
https://100best.3blmedia.com/, assessed on 1 January 2022). According to 3BL Media, the top 100 U.S. firms are selected from the 1000 largest publicly traded U.S. firms and included on the list every year, based on the evaluation of CSR performance and disclosure in terms of the six CSR components (environment, climate change, human rights, employee relations, governance, and philanthropy) and the one financial component. The evaluation is conducted with publicly available information on each factor contained in each component. A firm included on the list would garner substantial CSR-related recognition and reputation from the public (
Lewis 2018;
Lewis and Carlos 2023). Indeed, firms with superior CSR performance have improved their brand image and reputation by proactively engaging in CSR activities (
Laksmana and Yang 2009). Because a firm’s inclusion on the list is a reputable achievement and is indicative of its CSR-oriented business strategy, intensive CSR effort, and investment in CSR activities, we considered a firm’s inclusion on the list as an empirical proxy of CSR activities.
We obtained the remaining variables from Wharton Research Data Services (WRDS). We extracted our data for audit opinion, audit fee, SOX404, and material control weaknesses from Audit Analytics and the data on firm fundamentals and segments from Compustat. We obtained the governance data from the Institutional Shareholder Services (ISS) database.
We constructed our sample by obtaining 14,843 firm-year observations from the ISS governance database. We excluded 8908 firm-year observations with missing Compustat data. We excluded 1750 firm-year observations with missing audit fees, nonaudit fees, and audit opinion information. We also excluded 78 firm-year observations and 432 firm-year observations for SOX404 and segment information, respectively. We excluded 14 firm-year observations that have unusually longer audit report lags because of issues related to revenue recognition and legal matters resulting in a sample of 3661 firm-year observations.
Finally, we merge the result with data obtained from the 3BL media giving us our final sample of 3661 firm-year observations. We winsorized our continuous variables at 1% and 99% to minimize the effect of outliers. We report the summary of the sample selection in
Table 1.
3.2. Variables of Interest
Our independent variable of interest is
CSR_100, which is a composite dichotomous variable that has the value of one if a firm is included in the “100 Best Corporate Citizens” list for each of our sample years, and a value of zero otherwise. As discussed, we adopted this variable as an empirical proxy of corporate CSR activities to test
H1. The “100 Best Corporate Citizens” list also provides the rankings of the firms included in the list in terms of each of the six CSR components, environment, climate change, human rights, employee relations, and philanthropy. To test the
H2, we formed the six variables,
ENV_100,
CLI_CHG_100,
HUM_RGT_100,
EMP_REL_100,
GOVERN_100, and
PHILAN_100, representing each of the CSR components considered in the list, respectively. For example,
ENV_100 is a dichotomous variable equal to 1 if a firm is included in the “100 Best Corporate Citizens” list and ranked within 100 in the environment component, and 0 otherwise. The other five variables are also defined similarly, as shown in
Appendix A.
Following the literature (
Lamptey et al. 2021;
Bryan and Mason 2020), we adopted as our dependent variable
ARLP365 representing audit report lag, which is defined as the number of days between a firm’s fiscal year-end and the audit report date scaled by 365.
3.3. Control Variables
We used the following control variables in our model. The Altman’s ZSCORE (
Z_SCORE), TOBINQ (
TOBIN_Q), leverage (
LEV), return on assets (
ROA), auditor type (
BIG4), material weakness (
MCW), the natural logarithm of nonaudit fee (
LNAFEE), the natural logarithm of audit fee (
LAFEE), business segments (
BUSSEG), whether the firm is involved in litigation (
LIT), going concern opinion (
GC), firms with December fiscal year-end (
DEC), accelerated filer (
ACF), large-accelerated filers (
LACF), and auditor change (
AUDCH). We controled for governance using managerial entrenchment that we proxy by the variable
EINDEX. We also controled for managerial behavior using accrual earnings management (
EM_ABSDA) developed by
Kothari et al. (
2005). We included the year (
YR) and industry (
INDUSTRY) dummy variables in our model to control for the year and industry effect on the audit report lag.
3.4. Multivariate Regression Model
In estimating the association between
CSR_100 and audit report lag, we used robust regression to mitigate the effect of potential outliers or influential observations. In an untabulated result, we estimated the model using OLS, and the results are consistent with those obtained using robust regression. We use a modified version of the audit report lag model from
Tanyi et al. (
2010) to estimate our model for
H1 as below.
where:
ARLP365i,t is the audit report lag which we operationalize as the number of days between the firm i ’s fiscal year-end and the audit report date scaled by 365;
CSR_100i,t is our variable of interest which is a composite binary variable equal to one when firm i is listed in the “100 Best Corporate Citizens” issued by 3BL Media in year t and zero otherwise;
SIZEi,t is the size of the firm i in year t. measured by that natural logarithm of total assets;
Z_SCOREi,t is the altman’s Zscore
TOBIN_Qi,t is a measure of firm i’ s performance in year t;
LEVi,t is the leverage of the firm i in year t measured by total liabilities divided by total assets;
ROAi,t is the return on assets of firm i in year t measured as earnings before interest and taxes scaled by the total assets;
BIG4i,t is a binary variable equal to one when firm i is audited by a BIG4 audit firm in year t, and zero otherwise;
MCWi,t is a binary variable that is equal to one when firm i has material control weaknesses in year t, and zero otherwise;
LNAFEEi,t is the natural logarithm of the fees paid by the firm i in year t for nonaudit services;
LAFEEi,t is the natural logarithm of fees paid by the firm i in year t for audit services;
BUSSEGi,t is a binary variable equal to 1 if the firm i has more than one segment in year t, 0 otherwise;
LITi,t is a binary variable equal to one when firm i is engaged in a highly litigious industry in year t, and zero otherwise (2-digit SIC codes 28, 35, 36, 38, and 73);
GCi,t is a binary variable equal to one when firm i receive a going concern opinion in year t, and zero otherwise;
DECi,t is a binary variable equal to one when firm i has a fiscal year-end of December in year t, and zero otherwise;
ACFi,t is a binary variable equal to one when firm i is an accelerated filer in year t, and zero otherwise;
LACFi,t is a binary variable equal to one when firm i is a large-accelerated filer in year t, and zero otherwise;
AUDCHi,t is a binary variable that takes the value of 1 if a firm i changes auditors during the year t, 0 otherwise;
EINDEXi,t is a categorical variable that takes values from zero to six such that zero indicates that firm
i did not adopt any of the six entrenchment provisions in year
t used by
Bebchuk et al. (
2009) to create the index, whereas six indicates that firm
i adopted all six entrenchment provisions in year
t used in the EINDEX;
EM_ABSDAi,t is the earnings management variable operationalized by the absolute value of discretionary accruals using the
Kothari et al. (
2005) model.
To test H2, we replaced the independent variable, CSR_100, with each of the following CSR component variables, ENV_100, CLI_CHG_100, HUM_RGT_100, EMP_REL_100, GOVERN_100, and PHILAN_100.
We tested for multicollinearity using the variance inflation factor (VIF) and reported that the highest VIF is 4.5 for LAFEE. This VIF is lower than the critical value of 10 suggested in the literature. Thus, our model is not influenced by multicollinearity concerns. We depict the results of our multicollinearity test in
Table A2 of
Appendix A.
Next, we tested for homoscedasticity assumption, that is, whether our dependent variable has equal variability across the independent variables. Violations of the homoscedasticity assumption led to heteroscedasticity. We show the result of this test in
Table A3 of
Appendix A. Using the White test (
Halbert White 1980) we show that our models portray heteroscedasticity. Therefore, we rejected the null hypotheses in all three models. Hence, we used robust regression with fixed effects for our analyses to minimize the impact of the unequal variances in the residual.
