Institutional investors and earnings management associated with controlling shareholders' promises: Evidence from the split share structure reform in China

We examine the effectiveness of institutional investors in constraining aggressive earnings management induced by strong contractual incentives. To this end we focus on the consequences of earnings-related promises (covenants) negotiated between corporate controlling shareholders and minority shareholders during China's split-share structure reform, wherein failure to achieve profit benchmarks had the potential to transfer significant wealth from controlling to minority shareholders. Our initial analysis provides evidence that profit-promised firm-years are, on average, associated with income-increasing earnings management, and that this association is stronger for: (i) firm-years in which the profit-promise was satisfied, and (ii) firm-years in which proxies for the level of unmanaged earnings suggest that earnings management was needed to satisfy the promise. However, such benchmark-beating behavior is weaker for firms with higher levels of institutional ownership. Further analysis documents that the exit threat of institutional shareholders can discipline earnings management associated with profit promises. We also show that the effect of institutional shareholders in reducing earnings management associated with profit promises is greater for domestic mutual funds and for privately controlled firms. Interestingly, our evidence suggests that institutional investors only play an effective monitoring role over earnings management when their incentives are strongly aligned with those of other minority owners. In other cases, our evidence suggests that these investors may exacerbate the level of earnings management.
