Each Plan carries its own accounting system, organized by three different programs:

It reports all activities, revenues and expenses intended to provide administrative support to the management of PREVI and its Plans.

It reports all revenues related to the collection of contributions that make up the technical resources, and all benefit payment expenses.

It reports all activities related to the use of the several Plans' resources, revenues and variation on asset valuation, plus expenses and investments made.

The only program that all Plans share is the Administrative Program, once everybody benefits from PREVI’s management structure.
