Determinants and valuation implications of imperfect stock option disclosures

Using a sample of listed French firms in 2005, the year of mandatory IFRS adoption in the European Union (EU), we investigate the determinants of disclosure compliance of stock option expenses under IFRS 2, Share‐based Payment. Stock options are a popular means of executive compensation in France relative to other EU countries. Prior to 2005, French accounting standards and corporate governance regulations did not require recognition of option expense amounts and required minimal supplementary disclosures. There was also a perception that enforcement was imperfect, in particular with respect to IFRS 2. Given this setting, we explore what factors influence the willingness of firms to follow compulsory IFRS requirements in a weak regulatory setting. We find that overall compliance with IFRS 2 disclosure requirements increases with U.S. and U.K. institutional ownership, U.S. cross‐listing, provision of English language statements, and decreases with CEO and family ownership of the firm. We also investigate how stock market prices are affected by the recognition and disclosure of stock option expenses according to IFRS 2 in this regulatory setting and find that investors value option expenses positively, particularly when accompanied by high‐disclosure compliance. Our findings have implications for other jurisdictions in the process of adopting or converging to IFRS.
