Trends in material weaknesses for non-IPO companies
A 2023 KPMG study of public companies reveals common themes and business process areas associated with material weaknesses.

The study analyzed annual filings released by SEC-registered public companies between July 2018 and June 2023. Data was reviewed from the third-party research database Audit Analytics, and all MWs reported were aggregated and then summarized based on the underlying themes and affected business processes related to the MW.
For purposes of this report, the 2023 year considers MWs reported in any public company filing that was released between July 2022 and June 2023. The MWs reported in this year’s study came from companies with year-ends through June 30, 2023. KPMG notes that the data set underlying this study does not include S-1s for IPO companies that were first time filers during the time period of the report, but includes all companies once they have filed a 10-K.

79%
Lack of documentation, policies & procedures
Held steady at 99%-100% between 2019-2022 and declined to 79% in 2023. This means that at least one of the root causes for the MW was related to lack of documentation, policies and procedures; but additional causes may also be identified for each MW.
