NYSE Regulation (“NYSER”) is responsible for monitoring activities on the NYSE’s equities, options, and bonds markets – i.e., the New York Stock Exchange LLC (equities and bonds), NYSE Arca, Inc. (equities and options), NYSE American LLC (equities and options), NYSE National, Inc. (equities), and NYSE Chicago, Inc. (equities) (collectively, the “NYSE Exchanges”) – and for addressing non-compliance with the NYSE Exchanges’ rules and federal securities laws.

NYSER enforces both the NYSE Exchanges’ and their members' compliance with NYSE Exchange rules and applicable federal securities requirements. It also monitors and enforces listed companies’ compliance with applicable listing standards of the NYSE Exchanges. By performing these duties, NYSER supports the NYSE Exchanges’ efforts to promote just and equitable principles of trade, encourage free and open markets, and protect investors and the public interest. Many of these regulatory functions are performed directly by NYSER; others are performed by FINRA or other self-regulatory organizations pursuant to a regulatory services agreement, national market system plans, or other arrangements.
