Analyzed Economic Effects
5 provisions identified: 1 benefits, 4 costs, 0 mixed.
$39M Historical CAT Cost Recovery
MIAX Pearl will collect $38,964,855.34 in leftover historical Consolidated Audit Trail (CAT) costs from Industry Members through a new Historical CAT Assessment 1A. The assessment seeks to recover this amount from CAT Executing Brokers and will begin invoicing in June 2026 for May 2026 transactions.
CEBB/CEBS Allocation Split
Historical CAT Assessment 1A will allocate the $38,964,855.34 equally between CAT Executing Brokers for the Buyer (CEBB) and CAT Executing Brokers for the Seller (CEBS), with each group collectively responsible for $19,482,427.67.
Participants' One-Third Paid Via Loan Cancellation
Participants (the exchanges) will not be invoiced for their one-third share of Historical CAT Costs; instead, that one-third ($106,019,939.67 for Historical CAT Costs 1 in total) will be satisfied by cancellation of loans the Participants previously made to CAT LLC. Participants remain responsible for certain Excluded Costs separately.
Per-Share Fee Rate Set
The fee rate for Historical CAT Assessment 1A is set at $0.000002 per executed equivalent share. Executed equivalent shares are counted as 1 per NMS Stock share, 100 per listed options contract (or other applicable multiplier), and 0.01 per OTC equity share as described in the CAT plan.
Possible Fee Pass-Through to Customers
The Commission recognized that Industry Members may pass through CAT fees to customers for executed volume. That means brokers could pass these per-share charges on to trading customers in the form of fees or higher execution costs.
