The purpose of this paper is to empirically investigate the earnings quality (EQ) of IPO companies on the Polish capital market. The study included data from financial statements of companies that became public through the IPO process on the WSE between 2008 and 2011. In order to estimate EQ I used an approach based on measurement of abnormal accruals. This study has shown that the average magnitude of the incomeincreasing abnormal accruals in the pre-IPO period was significantly higher than in the post-IPO periods. This result is consistent with prior findings and the theoretical assumptions and provides an empirical evidence that Polish firms' managers engage in earnings management at the time of the IPO.
