PwC's online "SEC comment letter trends" for the period July 1, 2023, through June 30, 2024, is a consistently great tool that allows online exploration of recent Form 10-K and 10-Q comment letter trends and samples by industry or comment letter topic and provides easy access to topically relevant guidance.
Notably, based on an Audit Analytics analysis of comment letters for the 12 months ended June 30, 2024, compared to the 12 months ended June 30, 2023, the relative number of comment letters year-over-year on MD&A declined, whereas the relative number of comment letters on all other topics tracked, including non-GAAP measures and disclosure controls & ICFR, generally remained flat year-over-year. Comment examples by topic (non-GAAP measures, for example) are accessible with one click.
