Which employers count as oil, gas and mining here?
Oil and gas extraction, mining and support activities (codes 211110 to 213115) plus petroleum refining (324110 to 324199), grouped together so integrated oil companies sit with extraction. Sponsors here include ConocoPhillips, Exxon Mobil and Shell.
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 (618 of 653 plans here). Plan-paid expenses exclude fund expense ratios and employer-paid bills, so every figure is a floor, not the all-in cost.
