본 연구는 상장기업을 대상으로 비정상 투자 수준, 현금배당 그리고 초과현금보유 수준이 감사인의 감사위험과는 어떤 관련성이 있는지를 감사보수 및 감사시간 측면에서 실증적으로 분석하였다. 이를 통해 본 연구는 기업의 투자 및 배당의사결정 및 현금보유의 기업의사결정이 감사인의 입장에서 감사위험의 평가와는 어떤 관계가 있는지를 알아보았다. 분석을 위해 본 연구는 비정상 투자 수준을 Biddle et al.(2009)의 방법에 따라 추정하고(이하 INVEST), 또한 총투자를 연구개발비(R&D)와 비연구개발비(Non-R&D)로 나누어 분석한다. 또한 초과현금보유 수준은 Oler and Picconi(2014)에서 제안된 모형에 따라 추정하였다(이하 CASH). 그리고 현금배당(DIV)은 선행연구에 따라 현금배당을 수행한 기업이면 1, 아니면 0인 더미변수로 측정하였다. 분석기간은 2003년부터 2016년까지 유가증권 및 코스닥기업을 대상으로 감사보수(감사시간)의 최종표본 17,462개(17,300개) 기업/연 자료가 분석되었다. 실증결과는 다음과 같다. 첫째, 통제변수가 고려된 후에도 비정상 투자수준과 감사보수 및 감사시간 간에는 유의한 관계가 관찰되지는 않았다. 그러나 총투자를 R&D와 Non-R&D로 구분해 분석하면 비정상 R&D 투자지출이 클수록 감사보수와 감사시간 모두 유의하게 높고, 비정상 Non-R&D 투자지출이 클수록 감사보수와 감사시간 모두 낮게 나타났다. 둘째, 현금배당을 수행한 기업은 그렇지 않은 경우보다 감사보수와 감사시간 모두 유의하게 낮은 결과로 나타났다. 셋째, 초과현금보유 수준이 클수록 감사보수와 감사시간 모두 낮은 결과로 나타났다. 넷째, 추가분석에서 INVEST(R&D, Non-R&D), DIV 및 CASH 간의 두 조합적 상황에 따라 감사인의 감사위험에 어떤 영향을 주는지를 상호작용변수를 이용한 결과에 따르면, INVEST(R&D, Non-R&D)*CASH 및 DIV*CASH는 감사보수 및 감사시간과 유의한 관계가 나타나지 않았으나, R&D*DIV 및 Non-R&D*DIV는 감사보수를 증가시키고, R&D*DIV는 감사시간을 증가시키는 것으로 나타났다. 이를 종합하면, 본 연구는 감사인의 경우 총투자보다 이를 구분한 R&D와 Non-R&D(설비투자 등) 투자지출에 따라 감사위험을 달리 평가하고 있으며, 또한 현금배당과 초과현금보유는 오히려 감사인의 감사위험을 낮춘다는 것을 감사보수 및 감사시간을 통해 보여주었다는데 의미가 있다. 또한 본 연구의 결과에서는 현금배당을 하면서 동시에 R&D 투자지출이 과잉투자 되거나, 현금배당을 하면서 동시에 설비투자 등에 과잉투자가 이루어진 피감기업은 오히려 배당의 정보효과가 감소되어 감사인의 감사위험을 증가시킬 수 있음을 보여주었다. 따라서 이와 같은 본 연구의 발견은 감사보수와 감사시간의 결정모형을 다룬 연구나 투자효율성, 배당의 정보효과 그리고 현금보유를 다룬 관련연구에 추가적인 새로운 실증적 증거를 제공한다. 아울러 본 연구결과는 국내 상장기업들에서의 과잉투자 문제, 현금배당 및 초과현금보유 상황에 따라 감사인의 감사위험이 어떻게 달라지는지를 보여주고 있기 때문에 학계뿐만 아니라 실무계, 투자자, 규제당국 및 정책입안자에게도 유용한 정보를 더불어 제공할 것으로 예상된다.
Abstract
This study investigates whether the relation between the level of abnormal investment, cash dividends, and excess cash holdings and audit fees as well as audit hours. Specifically, we examine whether auditors’ audit risk by analyzing the relation between abnormal investment, cash dividends, and excess cash holdings and auditor pricing behavior as well as the behavior of auditors’ additional audit effort. Auditors’ risk assessments are ongoing and may uncover unexpected relationships and private information during analytical review procedures and management interviews. Exposure to business risks due to their association with the client motivates auditors to identify signals of audit risk because they impose additional audit costs (Bell et al. 2001; Gleason et al. 2017). The investment decisions are one of the most fundamental and important factors that determine the value of the firm and therefore investors’ wealth. Prior literature shows that high quality financial reporting and corporate governance mechanisms can help prevent or mitigate firm’s suboptimal investments by disciplining managers’ behaviors (Biddle et al. 2009). Thus, prior literature recognizes the possibility that firms may depart from this optimal level and either over- or under-invest can lead to risk-taking behaviors in corporate investment. Whereas, the ability to pay dividends is dependent on the availability of cash. In addition, recent studies suggest cash dividends convey information regarding the quality of firms’ reported earnings with dividend-paying firms reporting higher-quality earnings than nondividend-paying firms (e.g., Skinner and Soltes 2011; Tong and Miao 2011; Caskey and Hanlon 2013; Kim et al. 2016; Nam 2016 etc.). Meanwhile, prior research links excess cash holdings to risks associated with manager opportunism and external monitoring (e.g., Pinkowitz et al. 2006; Dittmar and Mahrt-Smith 2007; Gleason et al. 2017 etc.). On the other hand, Keynes (1936) claim that although firms reserve cash for precautionary motives, high levels of cash holdings often mitigate the demand for raising cash through external capital markets. Thus, there are from different perspectives. In that sense, our study synthetically extends these literature by examining whether the level of investment, dividends’ information, and excess cash holdings is associated with auditors’ assessment of their clients’ business risk. Specifically, our study extends the previous studies abnormal total investment classify into abnormal R&D investment and non-R&D investment, also dividend-pay firms, and excess cash holdings are associated with audit fees as well as audit effort in regard to auditors’ risk perceptions. For analysis, we follow Biddle et al. (2009) in estimating a firm’s likelihood of the level of abnormal investment. In particular, we divide total investment into R&D and non-R&D, respectively. Following Lawson and Wang (2016) and Tong and Miao (2011), our proxy for firms’ dividend payout policies is an indicator variable set equal to one if firm pays ordinary cash dividend in period t-1 (t), and zero otherwise. And we use the Oler and Picconi (2014) model to estimate excess cash holdings. Our sample covers KOSPI and KOSDAQ listed firms in non-financial industries from 2003 to 2016 (based on the dependent variable from 2004 to 2016). The empirical main findings of this study are following. First, after controlling for several factors that affect audit fees and audit hours, we find no a significant relation between abnormal total investment and audit fees as well as audit hours. Whereas, we find a positive and significant association between abnormal R&D investment and audit fees as well as audit hours, we also find a negative and significant association between abnormal non-R&D investment and audit fees as well as audit hours. These results suggest that total investment is associated with audit risk is different according to the sources (R&D versus non-R&D investment). Second, we find that dividend-paying firms are associated with lower audit fees and audit hours. This results suggest that divided policies provide auditors with assurance when clients exhibit higher earnings quality and cash dividends mitigate clients’ higher earnings manipulation risk. Third, we find a negative and significant association between excess cash holdings and audit fees as well as audit hours. Inconsistent with Gleason et al. (2017), we show that excess cash holdings may affect auditors’ assessments regarding the financial soundness instead of agency conflicts. Fourth, we classify sample into KOSPI versus KOSDAQ listed firms, we also find similar results. Merely, we find that a negative and significant association between dividend payouts and audit fees is more pronounced for KOSDAQ listed firms. As well, we find that a positive (negative) and significant association between R&D (non-R&D) investment and audit fees is more pronounced for KOSPI (KOSDAQ) listed firms. Finally, in additional analysis, we find that R&D or non-R&D investment, cash dividends and excess cash holdings have an interactive effect with respect to audit risk by auditors: We find that the positive and significant association between R&D investment with cash dividend-pay firms as well as non-R&D investment with cash dividend-pay firms and audit fees, we also find the positive and significant association between R&D investment with cash dividend-pay firms and audit hours. These results suggest that divided-pay firms tend to exhibit more over-investment than under-investment activity reinforcing our conjecture that many more outflow of cash will make it harder for the company as well as lower financial soundness may affect auditors’ assessments as business risk and audit risk. In summary, our findings suggest that auditors perceive abnormal R&D investment as a risk factor. On the contrary, non-R&D investment, dividend-pay firms, and excess cash holdings as having lower audit risk that they incorporate into audit fees and hours. In that sense, we provide new evidence on abnormal R&D investment, non-R&D investment, cash dividends, and excess cash holdings as one of determinants of audit fee and hour models from auditor’s perspective, who assesses the sources of business risk and audit risk based on client characteristic when auditing process. Thus, our study contributes to investment efficiency, dividend payout, cash holdings, and auditing literatures by being the first to show that auditors’ pricing as well as audit effort decisions at the same time. Therefore, our findings are provide to useful information, including academics as well as practitioners, investors, regulatory, and policymakers’ perceptions about importance of novel audit risk.
