1. Introduction
This study examines the impact of executives implicated in financial reporting fraud (hereafter fraud) on firms’ investment decisions. Also, it investigates how colluded executives in fraud influence investment decisions. We use hand-collected data of fraud cases in which executives are implicated or colluded using publicly disclosed Accounting and Auditing Enforcement Releases (AAERs) of the U.S. Securities and Exchange Commission (SEC). Prior studies suggested that more than half of executives are implicated in fraud, and of these cases, over 60% involve at least two executives [1, 2, 3]. Studies investigating fraud cases where executives are implicated (or colluded) have been limited, mainly due to the challenges of identifying executive involvement in AAERs.
The fraud triangle consists of three elements that underlie a fraudster’s decision to commit fraud: opportunities, incentives, and rationalization [4-6]. Prior studies primarily focused on examining factors related to opportunity and incentives that reflect circumstances [e.g., 7-12]. Rationalization, however, is an internal process within firms , and mainly observable at the individual level analysis. Due to the constraints of generalizable empirical data, research on rationalization in fraud has been limited.
Executives implicated in fraud may display aberrant attitudes to justify obscure accounting irregularities and hide them from investors, regulators, external auditors, and other stakeholders [
13]. This study examines the distinct behaviors of executives implicated in or colluded in fraud. Moreover, we focus on internal investment decision-making in firms to explore the fraud rationalization process. To date, there is little research that deals with the relationship between fraud and its effect on internal decision-making. This study fills the void by examining how executives use abnormal investment decisions as a means of rationalizing fraud.
Optimal investments are vital for sustainable firm growth. Underinvestment undermines a firm's growth potential, ultimately resulting in deterioration of the economic base. Conversely, overinvestment beyond an optimal level can strain a firm's cash flows and increase economic costs, thereby impeding firm growth. Overinvestment without commensurate returns can lead to financial constraints, triggering a vicious cycle of subsequent underinvestment. Therefore, investment decision-making is the most critical internal process for a firm's long-term sustainability.
This study relies on AAERs from 1981 to 2013 to create a sample of fraud firms with available investment data. These releases summarize enforcement actions subject to civil lawsuits brought by the SEC in federal court whether a firm’s financial statements were materially misstated; the charges brought against named executives; the year fraud began; the year fraud detected; and the amount of civil penalty if applicable. Recent fraud studies documented that use of AAERs decreases the likelihood of type I errors given that firms undergoing SEC investigations are subject to the most egregious manipulations [3, 11, 12]. A fraud-only analysis allows representation of fraud firms free from hidden bias. AAERs clearly identify fraud firms, names and roles of specific management team members, and what charges were laid against them, which is the core of identification methodology utilized in this study. However, the small sample size resulting from use of AAERs increases the probability of Type II errors, reducing the power of empirical tests and decreasing the generalizability of the results [3, 15]. We utilize bootstrap analysis to address the non-normality of fraud firms in our sample by estimating the resampling distributions. We thus acquire multiple bootstrap samples that represent the fraud population. By employing bootstrap analysis, we expand the sample size from 151 to 1,510 firm-level observations, thereby bolstering the reliability of our statistical analysis without relying on strict assumptions about the underlying distribution of the data.
The first analysis shows that when executives are implicated in fraud cases, it results in abnormal investment decisions. Analyzing Chief Executive Officers (CEOs), Chief Financial Officers (CFOs), and other executives separately, we find that abnormal investment decisions are more prevalent when the CEO or CFO is implicated. The findings indicate that executives implicated in fraud cases are more likely to rationalize their misconduct through over- or underinvestment than those unnamed in fraud cases. We speculate that named executives might perceive that they can compensate for distorted financial information through inappropriate investments. Moreover, to mask their own misdeeds, they may strategically choose to overinvest or underinvest [
13].
The second analysis presents evidence that collusive fraud among executives leads to abnormal investment decisions. Analysis according to executive roles indicates that CEO or CFO involvement in collusive fraud intensifies abnormal investment decision-making. Conversely, collusion among other executives than the CEO or CFO has no incremental impact on investment decisions. Li [
3] documented that the interconnectedness among top management team members fosters ‘groupthink’, consequently elevating the risk of accounting fraud. Building on Li's findings [
3], this study offers additional evidence that groupthink involving high-level C-suite positions in collusive fraud detrimentally influences investment decision-making.
Further analysis disaggregates investment by level (overinvestment, underinvestment) and find that executives involved in fraud generally overinvest rather than underinvest. However, if CEOs or CFOs are implicated or colluding in fraud, they tend to underinvest by not investing in profitable projects. In the next analysis, we disaggregate investment by type (capital expenditures, R&D expenditures, and acquisition expenditures); the results are qualitatively similar to the main results. This shows the robustness of our findings. Among the three investment types, all implicated executives in our sample invested in R&D inefficiently to hide or rationalize fraud. Inefficient investment of the other two investment types (capital expenditure and acquisition expenditures) occurred only when the CEO or CFO was involved. This indirectly suggests that R&D is an easier channel through which to disguise fraud than other investment types. Additionally, our results reveal that the duration of fraud influences the impact of implicated and colluded executives on abnormal investment, with longer durations showing increased impact.
This study contributes to the literature as follows. Firstly, by examining fraud cases involving implicated or colluding executives, this study provides insights into the rationalization element of the fraud triangle, an area that remains relatively unexplored. Secondly, this study offers supplementary empirical evidence to enhance the understanding of the relationship between fraud and investment decision-making initially provided by McNichols and Stubben [
13]. They anticipated that executives' awareness of fraud may impact decision-making processes, but their analysis was not differentiated based on this awareness. We verify that executives' awareness of fraud has a detrimental impact on investment decisions. Thirdly, this study expands the findings of Li [
3], who illustrated how groupthink negatively influences internal decision-making in firms. Executives who collude in fraud, especially CEOs and CFOs, make abnormal investment decisions through group thinking to conceal their wrongdoing. Fourthly, we discuss the usefulness of public disclosure of executive involvement or collusion via AAERs in the U.S. In firms where executives are implicated or colluded in fraud, there is an increased probability of making inefficient investment decisions, ultimately leading to a decline in the firm's sustainability. Investors can evaluate a firm's sustainability by analyzing the detailed fraud information provided in AAERs. This study underscores the importance of public disclosure of fraud by regulators to alert capital market participants.

6. Discussion and Conclusion
This study investigates the impact of executives involved in fraud on firms' investment decisions utilizing AAERs in the U.S. While previous studies primarily examined factors related to opportunity and incentives within the fraud triangle, rationalization has received limited attention due to data constraints. Executives implicated in fraud often show aberrant attitudes to rationalize accounting irregularities. This study fills the gap by exploring how executives use abnormal investment decisions as a means of rationalizing fraud in light of the critical role of investment decisions in a firm's long-term sustainability.
Analysis of AAERs from 1981 to 2013 reveals that executives implicated in fraud cases tend to make abnormal investment decisions, particularly CEOs and CFOs. Collusive fraud among executives exacerbates abnormal investment decision-making. The results also indicate that such executives generally tend to overinvest rather than underinvest, particularly in R&D expenditures, to conceal or rationalize fraud. The duration of fraud further amplifies the impact of implicated executives on abnormal investment.
By shedding light on the rationalization element of the fraud triangle and offering insights into the detrimental impact of fraud on investment decisions, this research can help investors, regulators, and academics. Investors may be able to evaluate a firm's sustainability by analyzing the detailed fraud information available in AAERs, in which information about fraud cases is continuously updated. Furthermore, this study underscores the importance and urgency of public disclosure of fraud by regulators to alert capital market participants. Lastly, academics interested in ethics-focused education in accounting departments will find this study useful. When students recognize how abnormal investment decisions can be made at the expense of curtailed growth or innovation due to fraud, increased awareness of ethical decision-making will be a preventive control over corporate fraud.
