Proposed Amendments to Rule 610 of Regulation NMS

The Commission is publishing for comment proposed amendments to Rule 610 under the Securities Exchange Act of 1934 ("Exchange Act') relating to access to quotations in listed options as well as fees for such access. The proposed rule would prohibit an exchange from imposing unfairly discriminatory terms that inhibit efficient access to quotations in a listed option on its exchange and establish a limit on access fees that an exchange would be permitted to charge for access to its best bid and offer for listed options on its exchange.
