New CAT Historical Assessment Fee
NYSE Arca is establishing Historical CAT Assessment 1A to collect $38,964,855.34 of past Consolidated Audit Trail (CAT) costs that were not invoiced previously. The fee rate will be $0.000002 per executed equivalent share payable to CAT LLC, and first invoices will be issued in June 2026 for May 2026 transactions.
Buy- and Sell-Side Split of Liability
The $38,964,855.34 remaining Historical CAT Costs 1 will be recovered equally from buy-side and sell-side CAT Executing Brokers: CEBBs collectively are responsible for $19,482,427.67 and CEBSs collectively are responsible for $19,482,427.67. These collective amounts will be recovered via Historical CAT Assessment 1A.
Fee Calculation and What Triggers It
Historical CAT Assessment 1A will be charged for each applicable transaction in Eligible Securities to the CAT Executing Broker identified in CAT Data. Executed equivalent shares are counted as follows: each NMS Stock share = 1; each Listed Options contract = multiplier (e.g., 100 executed equivalent shares); each OTC Equity share = 0.01 executed equivalent share; each transaction's fee is calculated by multiplying the executed equivalent shares by one-third and by the fee rate $0.000002.
Brokers May Pass Fees to Customers
The Commission recognized that Industry Members may pass-through CAT fees for customer executed volume, meaning brokers could charge customers for these CAT funding fees on executed trades. If firms choose to pass through the charge, customer-facing trade costs could reflect the new fee.
