401(k) Monitor

Insurance 401(k) plans with 5,000 or more participants

108 large 401(k) plans sit in insurance and reported 5,000 or more participants on their latest Form 5500. All of them are listed here, ranked by active participants.

Active participants means people still building up a balance, which is the count Form 5500 reports separately from total participants. Every plan links to its own page, where the figures below come with the filing they were read from.

The plans

Ranked by active participants, the same order the site publishes plan pages in. Assets are Schedule H total assets at end of plan year, in USD. Cost per participant is plan-paid administrative expense, and a filing that itemized none says so instead of showing a zero.
