These figures reflect what the plan administrator certified on Schedule H or Schedule I of the Form 5500 annual return and can be compared against 2 prior plan-year filings from the same sponsor shown below.

Across the 3 plan years American Mathematical Society has on file with PlainRetire (2022-2024), sponsor-wide plan assets have moved from $116M to $136M, a gain of 17.6%, while reported participants moved from 363 to 390 (+7.4%). The strongest year on file by total sponsor assets was 2024 at $136M; the softest was 2022 at $116M. Year-by-year, sponsor-wide filings show: 2022 - $116M in assets across 2 plans covering 363 participants; 2023 - $129M in assets across 2 plans covering 372 participants; 2024 - $136M in assets across 2 plans covering 390 participants.

By assets, American Mathematical Society Tax-Deferred Annuity Plan outranks 89% of the 126,618 plans that filed a Form 5500 for the 2023 plan year, and holds roughly 0.7x the national average plan size of $100M and 730 average participants.

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 2023 Form 5500 with a reported end-of-year asset figure (126,618 plans), rank American Mathematical Society Tax-Deferred Annuity 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.
