How many FINRA disclosures does AON Securities LLC have?

How big is AON Securities LLC?
AON Securities LLC operates 11 branch offices and is classified by FINRA as a small firm, registered in IL (Regional firm). FINRA BrokerCheck publishes branch-office counts but not a firmwide registered-representative headcount, so PlainAdvisorCheck measures firm size by branch footprint.

What is a FINRA disclosure?
A FINRA disclosure is a reported event on a broker-dealer's record, including regulatory actions, customer complaints, arbitration proceedings, and civil court events. Disclosures are part of the public record maintained by FINRA and do not necessarily indicate wrongdoing or proven violations.
Should I avoid AON Securities LLC because of its disclosures?
Not necessarily. Larger firms accumulate more disclosures simply because they operate more offices, so PlainAdvisorCheck grades each firm against same-size peers rather than on raw counts. AON Securities LLC carries 3 disclosures across 11 branch offices (about 0.27 per office). Review the nature of individual disclosures on FINRA BrokerCheck before making a decision.
