The market for audit services provided to public companies listed on the Polish capital market

Summary/Abstract: The aim of the article is to identify changes in the concentration on the market for audit services provided to public companies listed on the Warsaw Stock Ex-change. The additional aim is to identify changes in the level of rotation among firms providing audit services to public companies listed on the Warsaw Stock Exchange. The research conclusions were based on the analysis of 2 652 annual reports prepared in the years 2011-2016 by companies listed on the Warsaw Stock Ex-change. Reports came from the websites of the surveyed companies. The data was collected manually. It was found that in the years 2011–2016 the concentra-tion in the market for audit services provided to public companies increased. Six audit firms, referred to in the article as “leading” firms, provided their services to over half of public companies. Their share in the audit services market varied across sectors. The level of rotation of audit firms providing their services to public companies in particular sectors was also different. It should be pointed out that the level of concentration in the market for audit services provided to public companies in Poland is lower than the average level of concentration for all EU countries. In Poland, in 2015, the CR4 indicator was around 41%, while the aver-age value of this indicator for the EU countries was around 70%. So far, there has been no comprehensive analysis of the Polish audit services market in the rele-vant literature. This article seeks to fill a research gap in this respect.
