Brokers Billed Nearly $39M Retro Costs
If you are an Industry Member identified as a CAT Executing Broker (a CEBB or CEBS), the NYSE will collect the remaining $38,964,855.34 of historical Consolidated Audit Trail (CAT) costs via a new fee called Historical CAT Assessment 1A. CAT Executing Brokers will begin receiving monthly invoices in June 2026 based on their May 2026 transactions.
Per-Share Fee Rate and Billing Formula
The fee rate for Historical CAT Assessment 1A is set at $0.000002 per executed equivalent share. For each transaction the fee is calculated by multiplying the executed equivalent shares by one-third and then by the $0.000002 fee rate; invoices are issued monthly to CAT Executing Brokers for the prior month's transactions.
Exchanges' One-Third Paid Via Loan Cancellation
The Participants (e.g., the exchanges) will not be invoiced for the Historical CAT Assessment; instead their one-third share of Historical CAT Costs 1 (totaling $106,019,939.67) will be paid by canceling loans they previously made to CAT LLC on a pro rata basis. Participants also remain 100% responsible for certain Excluded Costs totaling $83,253,090.
