The Financial Industry Regulatory Authority is seeking public comment on four proposals consolidating NASD and New York Stock Exchange rules into a new single rulebook.

FINRA was created last July through the consolidation of NASD and the member regulation, enforcement and arbitration operations of NYSE. The creation of a single, unified rulebook is one of the major efficiencies that the regulatory merger is supposed to deliver.

The four areas covered by the proposals are financial responsibility, supervision and supervisory controls, books and records and investor education and protection. In addition, FINRA said it will soon be submitting a filing to the US Securities and Exchange Commission proposing to move NASD marketplace and procedural rules into the new FINRA rulebook.

Creation of a single, unified rulebook will be accomplished in phases, but it should be substantially completed over the next year. The deadline for submitting comments on the first set of proposals is June 13.
