Form 5500 information is as filed by the plan administrator with the Department of Labor and may be amended. Figures reflect the plan year shown, not current balances. Form 5500 contains no individual account balances. Look up the original filing at EFAST2.
In the plan year ending 31 Dec 2024, Arthur J. Gallagher & Co. Employees Savings and Thrift Plan covered 29,898 participants and held $3.90B in net assets. The plan is a 401(k) plan sponsored by Arthur J. Gallagher (Illinios), LLC. of Rolling Meadows, Illinois.
Net assets came to $130,377 per participant, well above the $62,774 median for defined contribution plans with 25,000 or more participants and well above the $92,294 median for defined contribution plans in finance and insurance. The figure is an average across everyone in the plan, including former employees with small balances; Form 5500 holds no individual account data.
The employer contributed $105M during the year, or $4,409 per active participant against a same-size median of $2,417; participants contributed $200M and $102M arrived as rollovers and other contributions. Benefits paid out totalled $342M.
Schedule C lists 4 service provider organisations paid $5,000 or more, with reported compensation of $881K: $29.48 per participant, below the same-size median of $36.41. Administrative expenses charged to the plan were $885K. Schedule C does not capture every cost: fees netted from fund returns and fees the employer pays directly are outside it.
Across the filings on record, net assets went from $680M in 2010 to $3.90B in 2024 (up 474%), and participants from 10,845 to 29,898 (up 176%).
The independent accountant's opinion on the financial statements was unmodified (unqualified), from an audit whose scope was limited under ERISA section 103(a)(3)(C) to exclude investment information certified by a bank or insurer.

Questions and answers
How big is Arthur J. Gallagher & Co. Employees Savings and Thrift Plan?
29,898 participants at the end of the plan year ending 31 Dec 2024, of whom 23,895 were active employees, with net assets of $3,898,012,907. Among defined contribution plans that places it in the 25,000 or more participants band, which held 608 plans in plan year 2024.
What does Arthur J. Gallagher (Illinios), LLC. contribute per participant?
The filing reports $105,353,571 in employer contributions for the year, which is $4,409 per active participant; the median for plans of the same type and size was $2,417 in plan year 2024. Form 5500 reports the total only. It does not state the match formula, and the per-participant figure is an average, not any one person's contribution.
What fees does the plan pay and how do they compare?
Schedule C reports $881,249 in compensation to service provider organisations, $29.48 per participant or 0.02% of net assets. The same-size median among plans reporting any Schedule C compensation was $36.41 per participant. Administrative expenses on Schedule H were $884,939. Investment costs deducted inside mutual funds and other pooled vehicles are not itemised on Form 5500, so these figures are a floor rather than a full cost.
Who runs the plan?
The sponsor is Arthur J. Gallagher (Illinios), LLC.. Recordkeeping or administration: Empower Annuity Ins Co. of America and Empower Advisory Group, LLC. Investment advisory or management: Empower Advisory Group, LLC. The financial statements were audited by FGMK, LLC. Form 5500 also names the plan administrator's signer and other individuals; this site publishes organisations only.
Was the audit opinion unqualified?
The filing reports an unmodified (unqualified) opinion from a limited-scope audit, in which the accountant did not audit investment information certified by a bank or insurance company. Unmodified (formerly "unqualified") is the standard clean opinion.
How current is this, and does it show my balance?
This is the Form 5500 for the plan year 1 Jan 2024 to 31 Dec 2024, received by the Department of Labor on 15 Oct 2025. Filings are due seven months after the plan year ends, or nine and a half with an extension, so the public record always runs a year or more behind. It contains plan-level totals only: no individual balances, contributions or names of participants exist in the data.
