Why this rule existsrationale

The same PUBLIC_PROFIT classification produces very different throughput depending on an index membership nobody is asked about, so two public companies register identically and one can send a hundred times more than the other. Knowing which side you are on before launch is the difference between planning an external vet and discovering mid-campaign that the throughput is not there.

How to fix itremediation

Check whether the company is a current Russell 3000 constituent. If it is not, plan an external vet into the launch schedule rather than assuming the public classification is enough — the starting class without one is the lowest tier, not the highest.

Check this yourselfattestation

No tool can settle this one for you. Here is the check, and what wrong looks like.

Is this company a current Russell 3000 constituent?

1Check the published constituent list — it is reconstituted each June, so a company can drop off without anyone noticing.
2If it is not on the list, plan an external vet into the launch schedule: the starting class without one is the lowest tier, not the highest.

What wrong looks like: Two public companies register identically and one can send a hundred times more than the other. Nothing fails; the throughput simply is not there when the campaign goes live.

Notesnotes

Informational rather than a rejection: nothing fails on this. The user checks the current constituent list themselves — it is published annually and reconstituted each June — and uses the answer to decide whether to buy a vet before launch.
