This paper discusses the implications of IFRS-Reporting Adoption in Accounting Information Relevance based on the article, “The impact of IFRS adoption on the value relevance of book value and earnings” published in the year 2011 and co-authored by Clarkson, Hanna, Richardson, and Thompson. The study examined how compulsory IFRS adoption in Australia and Europe impacted the ability of the earnings and book value reported to describe the stock prices, a matter for which little large-sample empirical proof is available. The paper also aligns with the international topic of accounting theory and current issues.
