Residual audit fee and real income smoothing: evidence from quoted non-financial firms in Nigeria

Abstract

PurposeThe study investigated the relationship between residual audit fee and real income smoothening, proxied as real operating cash flow and production expenditure smoothing of non-financial firms in Nigeria.Design/methodology/approachThe study relied on secondary data from annual financial statements of 75 firms in the non-financial sector from 2010 to 2019. The study estimated the residual audit fee using a modified model from several contexts to suit the Nigerian environment. The hypotheses were tested using the dynamic panel GMM estimation procedure.FindingsThe results showed a significant negative effect of residual audit fee on (real) operating cash flow smoothing and production expenditure smoothing of non-financial firms. The control variables showed mixed effects for the industry-related (firm size and profitability), auditor attribute (audit quality and audit report lag) and the board related (board size and board independence).Research limitations/implicationsThe firms included in the analysis were selected based on data availability from MachameRatios® and the occurrence of missing values for some of the variables used in the various estimation models may bias results.Practical implicationsThe study identifies the nexus between RAF and real earnings management practices of non-financial firms; and shows the implication of fee payment to the overall conduct of the audit. More so, the mixed findings from the CVs suggest that in the context of developing economies, shareholders and capital markets regulators should be watchful of residual audit fees and utilise it as a gauge for audit quality and also an indicator of opportunism and weak internal control in the firm in the future assessments.Social implicationsThe implication of the study stems from its relevance to the capital market stability and the potential negative disastrous effect of corporate failure from earnings management practices.Originality/valueThe study develops a newly residual audit fee model to explore the effect of RAF on real income smoothing rather than the widely used models from prior literature; secondly, the focus on real activities manipulation may present additional evidence that applies to developing countries rather the widely used accrual measurement technique from an economic bonding perspective.

Implications of directors’ education for audit fees: does the audit committee matter?

“…In this vein, when managers require a high-quality external audit, they send signals to the market about the credibility of financial statements (Ashbaugh and Warfield, 2003). Under such view, the fees paid to the auditor represent a positive signal to the market and improve the credibility of financial statements, thus increasing the confidence of users (Egbunike et al , 2023). As a result, better governed firms are charged higher audit fees because they require auditors to exert greater efforts and provide higher-quality audit services to send a signal of stronger transparency to the market (Knechel and Willekens, 2006; Karim et al , 2015).…”

The relationship between income smoothing and the cost of debt: evidence from the United Kingdom and Nigeria

“…However, the Nigerian economy is characterized by dispersed ownership which makes shareholders’ monitoring over management use of income smoothing difficult. This situation is also intensified by the present weak regulatory environment, which is a common situation in most developing economies (Egbunike et al , 2022). Further, accounting practices in Nigeria have been permeated by the prevalent corruption in the broader society (Wallace, 1992; Bakre, 2007; Abdul-Baki et al , 2021).…”
