Sidley Austin LLP of Chicago, Illinois sponsors Sidley Austin LLP Savings and Investment Plan, a 401(k) plan. Its Form 5500 for the plan year ending 31 Dec 2024 shows 6,029 participants (3,442 active) and $1.93B in net assets.
Net assets came to $320,456 per participant, well above the $64,499 median for defined contribution plans with 5,000 to 24,999 participants and well above the $73,951 median for defined contribution plans in professional, scientific and technical services. 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 $14.1M during the year, or $4,096 per active participant against a same-size median of $2,424; participants contributed $61.5M and $69.5M arrived as rollovers and other contributions. Benefits paid out totalled $176M.
Schedule C lists 15 service provider organisations paid $5,000 or more, with reported compensation of $698K: $116 per participant, well above the same-size median of $53.38. Administrative expenses charged to the plan were $286K. 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 $270M in 2009 to $1.93B in 2024 (up 616%), and participants from 4,154 to 6,029 (up 45%).
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 Sidley Austin LLP Savings and Investment Plan?
6,029 participants at the end of the plan year ending 31 Dec 2024, of whom 3,442 were active employees, with net assets of $1,932,030,718. Among defined contribution plans that places it in the 5,000 to 24,999 participants band, which held 2,605 plans in plan year 2024.
What does Sidley Austin LLP contribute per participant?
The filing reports $14,098,850 in employer contributions for the year, which is $4,096 per active participant; the median for plans of the same type and size was $2,424 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 $697,727 in compensation to service provider organisations, $116 per participant or 0.04% of net assets. The same-size median among plans reporting any Schedule C compensation was $53.38 per participant. Administrative expenses on Schedule H were $285,636. 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 Sidley Austin LLP. Recordkeeping or administration: Schwab Retirement Plan Services Inc.. Investment advisory or management: At Investment Advisers Inc., Cerity Partners LLC and Mercer Investment Consulting Inc.. The financial statements were audited by KPMG LLP. 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 13 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.
