Retirement Plan for Employees of Southwest Gas Corporation
Sponsored by Southwest Gas Corporation, Las Vegas, NV
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 Jul 2025, Retirement Plan for Employees of Southwest Gas Corporation covered 4,490 participants and held $1.18B in net assets. The plan is a defined benefit pension plan sponsored by Southwest Gas Corporation of Las Vegas, Nevada.
Net assets came to $261,773 per participant, well above the $87,935 median for defined benefit plans with 1,000 to 4,999 participants and well above the $187,668 median for defined benefit plans in utilities. The figure is an average across everyone in the plan, including former employees with small balances; Form 5500 holds no individual account data.
Employer contributions were $25.0M for the year ($14,140 per active participant) and benefits paid were $68.7M. In a defined benefit plan the employer's contribution follows funding rules rather than a match formula, so it can swing widely from year to year.
Schedule C lists 5 service provider organisations paid $5,000 or more, with reported compensation of $3.8M: $840 per participant, well above the same-size median of $325. Administrative expenses charged to the plan were $4.2M. 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 $447M in 2009 to $1.18B in 2024 (up 163%), and participants from 4,421 to 4,490 (up 2%).
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 Retirement Plan for Employees of Southwest Gas Corporation?
4,490 participants at the end of the plan year ending 31 Jul 2025, of whom 1,768 were active employees, with net assets of $1,175,358,799. Among defined benefit plans that places it in the 1,000 to 4,999 participants band, which held 1,540 plans in plan year 2024.
What does Southwest Gas Corporation contribute per participant?
The filing reports $25,000,000 in employer contributions for the year, which is $14,140 per active participant; the median for plans of the same type and size was $10,593 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 $3,773,505 in compensation to service provider organisations, $840 per participant or 0.32% of net assets. The same-size median among plans reporting any Schedule C compensation was $325 per participant. Administrative expenses on Schedule H were $4,235,783. 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 Southwest Gas Corporation. Investment advisory or management: Russell Investments. Trustee or custodian: Bank of New York Mellon. The financial statements were audited by McConnell & Jones, 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 Aug 2024 to 31 Jul 2025, received by the Department of Labor on 11 May 2026. 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.
