New PCAOB Publication Provides Auditors With Insights Related to Testing Transactions Between Broker-Dealers and Related Parties

WASHINGTON, Feb. 4, 2026

Today, the PCAOB released a staff publication, “Broker-Dealer Audit Focus: Related Party Transactions.”

Under federal law, the PCAOB has the responsibility to oversee firms that audit broker-dealers registered with the U.S. Securities and Exchange Commission.

PCAOB staff continues to identify deficiencies related to the testing of transactions between brokers and dealers and related parties (typically parents or affiliates). This edition of Broker-Dealer Audit Focus highlights key reminders for auditors of broker-dealers from PCAOB standards related to audit procedures involving a broker-dealer’s revenue and expense transactions with related parties. It also provides the staff’s perspective on common deficiencies observed in broker-dealer inspections and shares good practices that the staff has observed.
