On September 29, 2014, ISE Mercury, LLC (“ISE Mercury” or “Applicant”) submitted to the Securities and Exchange Commission (“Commission”) a Form 1 application under the Securities Exchange Act of 1934 (“Exchange Act”), seeking registration as a national securities exchange under Section 6 of the Exchange Act. On June 26, 2015, ISE Mercury submitted Amendment No. 1 to its Form 1 application.

The Commission is publishing this notice to solicit comments on ISE Mercury's Form 1 application, as amended. The Commission will take any comments it receives into consideration in making its determination about whether to grant ISE Mercury's request to be registered as a national securities exchange. The Commission will grant the registration if it finds that the requirements of the Exchange Act and the rules and regulations thereunder with respect to ISE Mercury are satisfied.

The Applicant's Form 1 application, as amended, provides detailed information on how ISE Mercury proposes to satisfy the requirements of the Exchange Act. The Form 1 application also provides that ISE Mercury would operate a fully automated electronic trading platform for the trading of listed options and would not maintain a physical trading floor. It also provides that liquidity would be derived from orders to buy and orders to sell submitted to ISE Mercury electronically by its registered broker-dealer members, as well as from quotes submitted electronically by market makers. Further, the Form 1 application states that ISE Mercury would be wholly-owned by its parent company, International Securities Exchange Holdings, Inc. (“ISE Holdings”), which also is the parent company of two existing national securities exchanges, ISE and ISE Gemini, LLC.

A more detailed description of the manner of operation of ISE Mercury's proposed system can be found in Exhibit E to ISE Mercury's Form 1 application.
