The Securities and Exchange Commission has approved a proposal by the Financial Industry Regulatory Authority (FINRA) that effective November 3, yield reporting requirements for transactions in securities eligible for Trade Reporting and Compliance Engine (TRACE) will be eliminated. Currently, a member firm that executes a transaction in a TRACE-eligible security is required to report yield under NASD Rule 6230(c)(13). Also, currently disseminated TRACE data includes the yields reported by firms. FINRA has amended NASD Rule 6230(c) to eliminate the requirement to report yield when a transaction in a TRACE-eligible security is reported to TRACE. In addition, FINRA amends its dissemination practices for TRACE data. Instead of disseminating a member-reported yield, FINRA will disseminate a Standard Yield that is calculated in the TRACE System (Standard Yield) for each transaction in a TRACE-eligible security, with limited exceptions. FINRA believes that disseminating Standard Yields will enhance the usefulness of disseminated TRACE data to market participants.
