The Impact of Earnings Management on the Reliability of Financial Statements: An Empirical Analysis of Discretionary Accruals and Reporting Quality
0 viewsAbstract
Through this study, I examine how earnings management practices impact the overall reliability and credibility of corporate financial statements. Financial reporting is designed to communicate transparent accounting information to capital markets, yet managers frequently utilize accounting discretion—primarily through discretionary accruals and revenue timing—to alter reported earnings. I conducted an empirical comparative study over a sample of 500 firm-year observations split into two distinct reporting groups: a low earnings management group (transparent reporting) and a high earnings management group (high discretionary accruals). I evaluated five primary performance and reliability indicators: earnings persistence, financial statement restatement rates, annual audit hours, cost of equity capital, and stock price crash risk. The results indicate a significant breakdown in financial reporting reliability under high earnings management. Firms engaging in aggressive discretionary accruals suffered a 48% reduction in earnings persistence, a 52% higher occurrence of financial restatements, a 34% increase in required audit hours, a 1.8% penalty in implied cost of capital, and a 61% higher stock price crash risk. The implications demonstrate that managerial opportunism degrades accounting quality, inflates information asymmetry, and imposes severe financial market penalties on firms that compromise financial statement integrity.
