pro rata basis financial
"distribution, on a pro rata basis for no consideration"
A "pro rata basis" means dividing or distributing something proportionally according to each person's share or interest. For example, if a group shares costs or profits, each person receives or pays a portion that reflects their contribution or ownership percentage. This method ensures fairness by allocating resources in line with individual stakes, which is important for investors to understand how gains, losses, or costs are fairly shared.
pecuniary interest regulatory
"except to the extent of its or his pecuniary interest therein"
