Published on:
April 5, 2016

SIFMA provides comment to the Securities and Exchange Commission (SEC) on proposed rule changes filed by The Nasdaq Stock Market LLC (NASDAQ) and New York Stock Exchange LLC (NYSE). The proposals address the determination of official closing prices when the exchanges are unable to carry out a closing transaction. Nasdaq and NYSE developed these proposals after a July 8, 2015, systems outage at NYSE raised the question of how NYSE would determine its official closing prices if it could not run its closing transaction.
