In their earnings releases, many companies make adjustments to their GAAP earnings, resulting in pro-forma earnings. These adjustments are a way for managers to provide investors with more accurate performance indicators, but managers can also use them opportunistically. This study aims to determine whether managerial opportunism affects the accuracy of pro-forma earnings. More specifically, we aim to examine the effect of executive compensation based on short- and long-term performance as well as board independence on the accuracy of pro-forma earnings. According to the results of our tests, these three parameters have no effect on the accuracy of pro-forma earnings. Our study does not therefore support the idea that opportunism plays a part in the publication of pro-forma results, but rather that such declarations are made for informational reasons.
