"The [DOL] 'clarified' a 2020 Trump DOL 'information letter' ... [following] complaints that the initial letter ... green lighted a private equity component in individual account plans, such as 401(k) plans, under certain circumstances.... The 2020 letter was a significant coup by the PE industry. It opened a wide swath of 401(k) plans with an estimated $7.3 trillion in assets (as of June 2021) to private equity investments.... The DOL's make-good is written in bureaucratic terms yet it is mostly unequivocal in admitting its earlier communication lacked even-handedness."
