Czy standaryzacja rachunkowości zwiększa znaczenie sprawozdawczości finansowej dla wartości rynkowej w sektorze bankowym?
Does standardisation of accounting improve the value relevance of financial reporting in banking sector?

Summary/Abstract: The paper aims at investigating the impact of the adoption of the International Financial Reporting Standards on the value relevance of consolidated financial reporting of banks in the emerging capital market of Poland. The investigation covers a sample of all domestically-based commercial banks listed on the Warsaw Stock Exchange over the period 1997–2013 that prepared consolidated financial statements both before and after 2005, when IFRS became mandatory. The research methods employed involved multiple linear regression analysis and the Chow test for structural break. The empirical evidence indicates that observed increase in the value relevance of consolidated book values of equity and net earnings of banks after adoption of IFRS is statistically insignificant. Moreover, the descriptive power of the aforementioned accounting variables appears to have in fact diminished in the period succeeding the adoption. The obtained results are therefore consistent with the findings of previous studies regarding both banking and non-financial enterprises sector in the Polish capital market.
