When the SEC reviews financial statements and disclosures of public firms, it may send a comment letter to the company if it has questions or sees problems. You can learn a lot from these letters about fair value measurement issues. PwC has posted its latest version of “SEC Comment Letter Trends“ (comment letters publicly issued in the 12 months ended March 31, 2019), which includes topics such as business combinations, fair value (valuation techniques and inputs), and goodwill and other intangibles. Examining the issues in the comment letters can help you make sure you have addressed these areas properly in your own engagements.
