CBOE Holdings, Inc. (BATS: CBOE | NASDAQ: CBOE) today announced that the CBOE Futures Exchange (CFE) will be the first of the CBOE Holdings exchanges to migrate onto the Bats technology platform, with an expected switch-over on Sunday, February 25, 2018. The migration of the C2 and CBOE options exchanges will follow, with those dates to be announced later.

All CBOE and Bats exchanges will continue to operate normally throughout the migration process, and the CBOE trading floor will remain open to serve CBOE's options market. Beginning in July, CFE trading privilege holders (TPHs) may begin requesting new connectivity and in September, basic connectivity testing will begin. Throughout the fourth quarter of 2017 and into the first quarter of 2018, customers will be given numerous testing opportunities to ensure preparedness for CFE's planned switch-over on February 25, 2018.

"With our two companies now united as CBOE, our team is focused on executing a seamless technical and operational integration of the CBOE, C2 and CFE exchanges onto Bats technology," said CBOE Chief Information Officer Chris Isaacson. "We have a detailed roadmap to navigate through this multi-year process and intend to work very closely with all industry participants to ensure a smooth migration."

"Bringing together CBOE's and Bats' different, yet complementary, businesses is expected to provide many benefits to customers and enable CBOE to better serve our marketplace, including, over time, streamlining our technology," commented Andy Lowenthal, CBOE Head of Global Derivatives. "We plan to incorporate the functionality already offered by CBOE into Bats' state-of-the-art technology platform."

"We look forward to delivering to market participants the planned benefits and efficiencies of this integration," added Bryan Harkins, CBOE Head of U.S. Equities and Global FX. "We are particularly excited about the new product opportunities and having the ability to not only touch every aspect of the product development and trading cycle, but to create strong links between CBOE and Bats asset classes that are becoming increasingly interdependent."

An overview of the integration plan and detailed roadmap for CFE's migration is available on the CBOE integration website at www.cboe.com/BatsIntegration. The website will serve as a primary information resource for customers and market participants throughout the integration. This week, CBOE Holdings plans to post a Technical Integration FAQ regarding CFE-specific functionality. Planned FAQ topics include connectivity, certifications, market data and billing. In addition, in May an updated guide for CFE Technical Specifications is planned to be posted to the website.

On Wednesday, March 29, 2017, at 11:30 a.m. CT, CBOE will hold the first of a series of informational customer conference calls covering the technology integration. The call will feature Chris Isaacson, CBOE's Chief Information Officer, Andy Lowenthal, CBOE's Head of Global Derivatives, and Bryan Harkins, CBOE's Head of U.S. Equities and Global FX.
