100% (dollar-for-dollar) of the first 3% of pay, then 50% of the next 2% of pay
Which employers count as construction here?
Building construction, heavy and civil engineering, and specialty trade contractors (codes 236110 to 238990). Sponsors here include Turner and Fluor.
The code is the IRS principal business activity code the sponsor itself puts on Form 5500, line 2d. Medians count only plans whose Schedule H shows a positive plan-paid administrative expense (3,310 of 3,507 plans here). Plan-paid expenses exclude fund expense ratios and employer-paid bills, so every figure is a floor, not the all-in cost.
