The short version
MODE 2 OF 2
What the primary record establishes
SEC Rule 15c3-3 provides separate reserve computations for customer accounts and proprietary accounts of brokers and dealers, or PAB. The SEC staff FAQ explains daily calculations for carrying firms that meet the applicable average total credits threshold of $500 million.

What the distinction changes
The formulas compare specified credits and debits. If an $8 million amount is classified in the customer calculation but belongs in PAB, a combined total can remain unchanged after correction while the individual computations change.
What to check before drawing a conclusion
Maintain separate reconciliations for the two populations. A daily process benefits from identifiable input versions and controls for late entries or reruns, so staff can reconstruct why the two calculations moved on a particular date.
