Abstract

This paper examines the effect of regulations (i.e., the Sarbanes‐Oxley Act and Regulation G) on both the timing of earnings announcements and their relative informational role. I find that after the regulation of earnings announcements was instituted, firms began issuing less timely earnings announcements, and those announcements have become more important for shareholders. Ceteris paribus, after the regulations, firms have disclosed their fiscal year‐end announcements more than four days later than they had prior to regulatory changes. My results are robust to sensitivity analyses that control for concurrent earnings announcement disclosures and other changes instituted by the Sarbanes‐Oxley Act. Further, I find evidence suggesting that the relative informational role of earnings announcements has increased significantly in the post‐regulation period. This study highlights a shift in both the timeliness and investor perceptions of earnings announcements spurred by the implementation of regulatory oversight, indicating a trade‐off of timeliness for relevance. L'incidence de la réglementation sur la rapidité de publication des communiqués sur les résultats et leur rôle informationnel L'auteur étudie l'incidence de la réglementation (Loi Sarbanes‐Oxley et Règlement G) sur la rapidité de publication des communiqués sur les résultats et leur rôle informationnel relatif. Il constate qu'après l'instauration de la réglementation régissant les communiqués sur les résultats, les sociétés se sont mises à publier moins rapidement leurs communiqués qui ont d'autre part gagné en importance aux yeux des actionnaires. Toutes choses égales par ailleurs, après l'adoption de la réglementation, les sociétés ont publié leurs résultats de fin d'exercice au‐delà de quatre jours plus tard qu'ils ne le faisaient avant les modifications réglementaires. Les résultats de l’étude résistent aux analyses de sensibilité visant à contrôler la publication simultanée de communiqués sur les résultats et d'autres modifications apportées par la Loi Sarbanes‐Oxley. L'auteur relève en outre des données qui laissent croire que le rôle informationnel relatif des communiqués sur les résultats s'est sensiblement accentué dans la période postérieure à la réglementation. L’étude met en lumière un changement tant dans la rapidité de publication des communiqués sur les résultats que dans la perception qu'en ont les investisseurs par suite de la mise en place de la surveillance réglementaire, ce qui révèle l'existence d'un arbitrage entre rapidité et pertinence.
