Fee Rate Determination and Assessed Rate
The Operating Committee set an initial Fee Rate of $0.000003799483243631228 per executed equivalent share and then divided and rounded that amount so CEBBs and CEBSs will be assessed a fee rate of $0.000001 per executed equivalent share. For each transaction the fee is calculated using executed equivalent shares.
How Transactions Count for Fees
For fee calculations, executed equivalent shares are defined so that each executed share in NMS stocks counts as one executed equivalent share, each executed listed options contract counts by its contract multiplier (e.g., 100 executed equivalent shares per contract unless another multiplier applies), and each executed share in OTC Equity Securities counts as 0.01 executed equivalent share.
Monthly Billing and First Invoice Timing
CAT Fees are billed monthly based on the prior month's executed equivalent shares (each month while CAT Fee 2026-1 is in effect). The filing notes the first invoice for CAT Fee 2026-1 would be in June 2026 (after the May 1, 2026 start).
