This paper provides an analysis of the implications of the Feltham and Ohlson (1995) model for the relationship between unexpected security returns and unexpected earnings and cash flows. A simplified version of the Feltham and Ohlson linear information model is utilized to provide an intuitive explanation of the coefficients in the unexpected returns equation and to show that incremental information content for unexpected free cash flow beyond accounting earnings in the model depends on the existence of positive net present value (NPV) investment opportunities. The paper concludes by arguing that the model provides useful insights into factors that may influence the empirical relationship between security returns and accounting data. Résumé. L'auteur expose les résultats d'une analyse des répercussions du modèle de Feltham et Ohlson (1995) sur la relation entre les rendements imprévus des titres, d'une part, et les bénéfices et les flux monétaires imprévus, d'autre part. Il a recours à une version simplifiée du modèle d'information linéaire de Feltham et Ohlson pour expliquer intuitivement les coefficients de l'équation des rendements imprévus et pour montrer que, dans le modèle, le contenu marginal en information supérieur des flux monétaires disponibles imprévus par rapport aux bénéfices comptables dépend des possibilités d'investissement existantes offrant une valeur actualisée nette (VAN) positive. L'auteur conclut en affirmant que le modèle livre des renseignements utiles quant aux facteurs susceptibles d'influencer la relation empirique entre les rendements des titres et les données comptables.

Research suggests that the standard model used to detect opportunistic shifting of core expenses to special items is potentially biased. Such bias has been attributed to the use of accruals, including special item related accruals, as a control for the impact of performance on core earnings in this model. This paper provides an improved classification shifting model which both tests for such accruals-related bias and controls for other sources of error in the measurement of shifting. The paper also modifies conventional market rationality tests in accounting research to examine new dimensions of rationality in relation to measurement and valuation of shifting. The main empirical findings are as follows. First, the improved classification shifting model provides strong evidence of shifting and rejects the hypothesis that inclusion of accruals in the model causes bias. Second, estimates of shifted core expenses generated by the improved model exhibit forecasting properties of shifted earnings. Third, rationality test results are broadly consistent with rationality in relation to shifted core expenses but indicate possible partial (ir)rationality in relation to adjusted special items (i.e., special items excluding shifted core expenses). Further analysis of the latter findings, however, suggests they are more likely related to risk than irrationality. Overall, the paper contributes to improved measurement of shifting and highlights the importance of considering rational expectations when examining stock returns associated with shifting.
