"CLAS - Sec 11A P 2.2" likely refers to Section 11A of the Securities Exchange Act (SEA), dealing with National Market System (NMS) plans and SRO oversight, and perhaps Paragraph 2.2 within a specific rule or order under that section (like 17 CFR § 242.608(e) or NMS Rule 608(e)), often involving exemptions or de minimis exceptions for trade-throughs or fair access, as seen in SEC orders related to ITS/CAES plans and Regulation NMS, aiming to perfect market mechanisms.
