This study investigates whether fourth-quarter adjustments are significantly different from the previous three, thereby limiting the reliability or faithful representation of the firms' results for each quarter. This study includes four years (2003–2006) of quarterly financial information of 353 Canadian public companies. Our results indicate that the volatility of net income in each of the first three quarters is considerably lower than in the final quarter. While lower volatility can improve predictability, the resulting relevance may be limited. The low volatility of reported earnings in the first three quarters suggests that either earnings management is taking place or that management may not be exercising sufficient care at the end of each of the first three quarters on the measurements that generally accepted accounting principles call for and readers of financial statements expect. This could result in quarterly financial statements that do not faithfully represent the underlying resources and obligations of the reporting firms at the end of the quarter, or the firm's performance during the quarter. Our findings support Boritz's proposition for increased audit requirements for interim reports and changes in the approach to the annual audit to integrate it more closely with interim financial reporting. 收起
