The study looked at how Greek companies' financial statements changed when they switched from Greek to International Accounting Standards. They found that under the new standards, assets like buildings and debts were valued higher. The values of certain financial numbers also differed between the two standards. Interestingly, book value became more important under the new standards, while net income was less significant. Adjustments made to the old standards improved the relevance of financial information, but adjustments to book value did not.
