Asset totals and participant counts reflect a single plan year snapshot and can change materially with market conditions, plan mergers, or workforce changes. Fields such as "net income" include both realized investment performance and contribution/distribution flows, a single-year figure does not by itself indicate plan health or participant outcomes. This page summarizes public DOL disclosures for research and educational purposes only and is not retirement, tax, legal, or financial advice. Before making decisions about your own retirement benefits or evaluating an employer's plan, verify the underlying filing directly via the DOL EFAST2 system and consult a qualified professional.

How the percentile is calculated: we count every plan that filed a 2024 Form 5500 with a reported end-of-year asset figure (116,472 plans), rank Knowles Corporation 401(k) Plan against all of them by total assets, and report the share of those plans it outranks. A plan reporting no asset figure for the year is excluded from the ranking rather than assumed to be zero.
