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.
Rio Tinto America Inc. of South Jordan, Utah sponsors Rio Tinto America Inc. Retirement Plan, a cash balance pension plan. Its Form 5500 for the plan year ending 31 Dec 2024 shows 7,443 participants (1,472 active) and $638M in net assets.
Net assets came to $85,750 per participant, close to the $87,623 median for defined benefit plans with 5,000 to 24,999 participants and close to the $88,081 median for defined benefit plans in mining. The figure is an average across everyone in the plan, including former employees with small balances; Form 5500 holds no individual account data.
Schedule C lists 6 service provider organisations paid $5,000 or more, with reported compensation of $3.6M: $483 per participant, well above the same-size median of $232. Administrative expenses charged to the plan were $5.4M. 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 $322M in 2009 to $638M in 2024 (up 98%), and participants from 7,190 to 7,443 (up 4%).
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.

What does Rio Tinto America Inc. contribute per participant?
This filing has no Schedule H financial statement, so employer contributions are not reported here.
What fees does the plan pay and how do they compare?
Schedule C reports $3,596,873 in compensation to service provider organisations, $483 per participant or 0.56% of net assets. The same-size median among plans reporting any Schedule C compensation was $232 per participant. Administrative expenses on Schedule H were $5,389,008. 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 Rio Tinto America Inc.. Investment advisory or management: Pimco and Mercer. Trustee or custodian: Northern Trust Company. The financial statements were audited by BDO Usa,p.c.. 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 10 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.
