In November 2021 the SEC settled with McKinsey's investment arm MIO Partners, finding it failed from 2015 to 2020 to enforce policies preventing misuse of material nonpublic information held by McKinsey partners on its investments committee. MIO was censured and paid an $18 million penalty.

A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars.

What is alleged to have happened

The Securities and Exchange Commission instituted and settled the proceeding on November 19, 2021 under the Investment Advisers Act.

The order finds MIO allowed active McKinsey partners who held client information, and who saw MIO's own investment information, to oversee its investment decisions without policies designed for the risk of misuse. It charges the policies failure, not trading on inside information.

MIO agreed to a censure and an $18,000,000 civil penalty. The insider-trading tag was removed as a compliance-policy case.
