The Public Company Accounting Oversight Board said Monday lapses in broker-dealer audits continue to be widespread four years after it was given the responsibility of reviewing the reports by the Dodd-Frank Act.

The PCAOB’s new report says deficiencies were found in 70 of 90 brokerage audits done in 2013 at 60 firms.

The most common lapses were in material inadequacies, net capital reporting, the risk of material misstatement due to fraud, revenue recognition, and reliance on records and reports.

Since the inception of the brokerage review, faults have been uncovered in 87 percent of the audits.

The problems have been consistently worrisome among brokerages and audit firms of all kinds.

“Inspectors saw a high percentage of observations across the firms inspected … regardless of how many broker-dealer audits were performed by the firm,” the report said.

This year, 21 of the 90 brokerage audits examined violated SEC auditor independence requirements.
