Measuring fair value of an asset or a company will require a sharper focus on the part of CFOs as changes to fair-value accounting go into effect in the next financial-reporting period. Companies are still in the process of implementing International Financial Reporting Standard No. 13, which went effect Jan. 1. IFRS 13 is intended to give investors a better way to analyze corporate assets and remain aligned with generally accepted accounting principles in the U.S. The International Accounting Standards Board and the Financial Accounting Standards Board issued the standard in 2011.
