Customer Protection

SEC 15c3-3 provides regulatory safeguards regarding the custody and use of customer funds and securities held by broker-dealers. With certain exceptions, the rule requires all registered broker-dealers to comply.

Specifically, the second part of the rule requires firms to determine the amount of funds that must be deposited into special reserve bank accounts in the event funds due to customers exceed those due from customers. The same applies to the proprietary accounts of brokers.


  • Execute daily, weekly, or monthly calculations
  • Lack of automation

  • Complex data management
  • Disparate data sources

Questions to Consider

  • Do we have a plan to eliminate the manual processes upon which we currently rely for calculation and reporting?
  • Are we confident that we can correctly incorporate rule-changes into our current calculation engine?
  • Do we have transparency into our data and calculations at a granular level?
  • Does our technology enable us to efficiently ingest and process large data sets?

  • Are we prepared for heightened regulatory scrutiny of our data, calculation, and reporting processes?
  • Are we satisfied that our overall data management and governance capabilities meet regulatory expectations?
  • Are we confident that we have established repeatable processes that withstand examination?
