PAO(ORs)AOC is primarily responsible for holding and maintaining the pay and provident fund accounts of approximately 30,000 AOC personnel below officers rank(PBORs).

In addition to the maintenance of the IRLAs of the effective PBORs, PAO also maintains the closed IRLAs of non-effective personnel and ensures payment of any dues which may come to light as due to them subsequent to their final settlement.

The entire work of the PBORs has been computerized and being processed at its DDP Center with effect from November, 2001. The system relies on the software developed "in-house" by the department in COBOL on UNIX based environment. This is now switched over to more current RDBMS based on-line System called "Dolphin".
