Stock Exchange Files New Fees for Old Audit Trail Costs
Published Date: 5/27/2026
Notice
Summary
The Long-Term Stock Exchange (LTSE) is setting new fees for industry members to cover some leftover historical costs from the National Market System Plan for the Consolidated Audit Trail. These fees apply to costs from before 2022 that weren’t fully billed before. If you’re part of the industry, expect these charges to kick in right away and help wrap up past expenses.
Analyzed Economic Effects
4 provisions identified: 0 benefits, 4 costs, 0 mixed.
$39M Outstanding CAT Costs To Recover
LTSE will recover $38,964,855.34 of historical Consolidated Audit Trail (CAT) costs incurred before January 1, 2022 that were not invoiced under Historical CAT Assessment 1. The remaining amount will be charged collectively to Industry Members: CEBBs are responsible for $19,482,427.67 and CEBSs are responsible for $19,482,427.67.
Per-Share Historical Fee Rate Set
The Operating Committee set the Historical CAT Assessment 1A fee rate at $0.000002 per executed equivalent share. For each transaction, the Historical CAT Assessment is calculated by multiplying the number of executed equivalent shares by one-third and then by the Historical Fee Rate.
Fees Charged to CAT Executing Brokers
Historical CAT Assessment 1A will be charged to each CAT Executing Broker (CEBB and CEBS) for applicable transactions in Eligible Securities, as identified in CAT Data fields (e.g., Equity Order Trade, Option Trade, TRF/ORF/ADF transaction events).
Filing Is Immediately Effective
LTSE filed the proposed rule change on May 15, 2026 and the notice is one of immediate effectiveness; the Historical CAT Assessment 1A fees may be implemented right away to begin recovering the outstanding historical costs.

2026-17183, Regulation Crypto Assets
The Securities and Exchange Commission ("Commission") is proposing new rules to create a tailored offering regime for certain investment contracts involving crypto assets. The proposed offering regime is intended to facilitate capital formation and accommodate innovation within the crypto asset markets while, at the same time, ensuring that investors are adequately protected and provided with the information they need to make informed investment decisions. The proposed rules would be set forth in a new regulation titled "Regulation Crypto Assets" and would include two exemptions from the registration requirements of section 5 of the Securities Act of 1933. The first exemption would permit offerings of up to $5 million during a four-year period. The second exemption would permit offerings of up to $75 million during each 12-month period. Under both exemptions, issuers would be required to make certain principles-based narrative disclosures available to their investors. In addition, issuers under the second exemption would be required to provide financial statements and would be subject to ongoing reporting requirements. Issuers that rely on these exemptions would remain subject to the antifraud and antimanipulation provisions of the Federal securities laws. The proposed rules also would include a conditional safe harbor from the term "investment contract" in the definitions of "security" in the Securities Act of 1933 and the Securities Exchange Act of 1934. If the conditions of that proposed safe harbor are satisfied, then a crypto asset would be deemed not to be subject to an investment contract for purposes of those definitions of "security."
