The purpose of this paper is the link between women on management board and the value relevance of fair value accounting according to IFRS 13. The empirical quantitative study covers a sample of German companies listed at the Prime Standard of the Frankfurt Stock Exchange for the business years 2013-2015 (411 firm-year observations). Value relevance is measured by the modified Ohlson (1995) model and we separate fair value accounting in level 1, level 2 and level 3 fair values. Multiple regressions state that female members in the man-agement board do have a positive impact on the value relevance of fair value accounting according to IFRS 13. Surprisingly, gender diversity only has a significant impact on the value relevance of fair valued assets on level 1 and 2 (“mark to market”) but not on level 3 (“mark to model”).
