Support Activities for Water Transportation: retirement plans
Plans whose sponsor entered this principal business activity code on Form 5500.
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. The business code is chosen by the filer from the list in the Form 5500 instructions.
For plan year 2024, 73 retirement plans in support activities for water transportation with 100 or more participants filed Form 5500: 55 defined contribution and 18 defined benefit. They reported 100,597 participant records and $19.6B in net assets, counting every plan on the form.
The median defined contribution plan held $57,186 per participant, above the national median of $53,031, and its employer put in $3,237 per active participant (national: $2,174). Among plans reporting Schedule C compensation the median was $171 per participant against $123 nationally.
Employers contributed $855M and participants $139M during the year, and the plans paid out $1.04B in benefits.
In 2009 the same group numbered 67 plans with $4.74B; by 2024 it was 73 plans (up 9%) and $19.6B (up 312%). From plan year 2023 the 100-participant line counts participants with account balances, which moved many plans to the short form.

Plan year is the year in which the plan year began. The drop in large plans from 2023 follows a rule change: the 100-participant line now counts participants with account balances, so many plans moved to the short form.

Questions and answers
How many retirement plans are there in support activities for water transportation?
73 plans with 100 or more participants filed Form 5500 for plan year 2024, out of 99 pension plans on the full form. Smaller plans file Form 5500-SF and are counted separately where shown.
What is the typical 401(k) balance in support activities for water transportation?
The median defined contribution plan reported $57,186 in net assets per participant (middle half of plans: $31,960 to $123,532); nationally it was $53,031. This is a plan-level average that includes former employees, not a typical person's balance.
What do employers contribute in support activities for water transportation?
The median defined contribution plan received $3,237 in employer contributions per active participant, against $2,174 nationally. Plans with no employer contribution are included at zero.
What are average 401(k) fees in support activities for water transportation?
Among defined contribution plans that report any Schedule C compensation, the median was $171 per participant and 0.30% of net assets (nationally $123 and 0.26%). Schedule C leaves out fund expense ratios and fees the employer pays, so it understates total cost.
Where does this come from?
Form 5500 annual reports in the EBSA research files, with filings received through 24 Aug 2026. Medians are computed by this site across plans with 100 or more participants.
