Coincident and forecast relevance of accounting numbers

Purpose – Value relevance studies, in particular international comparative studies, use market values sampled at different dates relative to the fiscal year-end. This paper aims to contribute a theoretical and empirical analysis of the relationship between value relevance and the month of market value sampling. Design/methodology/approach – The paper examines two components of value relevance, coincident relevance and forecast relevance, which the paper develops on the basis of the Ohlson model. The paper measures value relevance by estimating separate panel-data regressions for each of the 12 months around fiscal year-end. The sample consists of companies listed in two continental European countries, France and Germany, over the 1989-2008 period. Findings – In both country panels, the paper finds that overall value relevance is higher when market value is sampled before or close to fiscal year-end, but incremental value relevance varies between domestic and International Financial Reporting (IFRS) accounting standards. Regression results reveal significant variations in coefficients over the following months of market value in French panel and its IFRS sub-sample only. Research limitations/implications – The scope of the study is limited to the average value relevance parameters of companies listed on stock exchanges in France and Germany. Future research may be devoted to other countries and study additional determinants of value relevance. Practical implications – The study shows that the selection of the month of market value sampling can have significant impact on value relevance regression results. Therefore, sensitivity analysis needs to be included in research studies which rely on the value relevance approach. Originality/value – The paper contributes the first systematic analysis of the variation in value relevance parameters in response to the selection of the month in which market value is sampled.
