Business Continuity Plan

The Chicago Stock Exchange (“CHX” or the “Exchange”) places a high priority on providing a reliable and resilient trading platform for our Participants to trade securities at the CHX. The Exchange also places a high priority on the safety of its staff, protection of Exchange assets and records, and open communication with its Participants and other National Market System participants.

The Chicago Stock Exchange Business Continuity Plan (“BCP” or the “Plan”) was developed to meet the inevitable challenges presented by a Significant Business Disruption (SBD). The Plan complies with the regulations and guidelines of the U.S. Securities Exchange Commission (SEC).

The Plan is reasonably designed to respond to most SBDs; however, given the unpredictably of some SBDs, the CHX cannot guarantee system availability or recovery timeframes. The CHX fulfills the SEC’s Regulation SCI requirement to maintain backup and recovery capabilities that are sufficiently resilient, geographically diverse and reasonably designed to achieve next business day resumption of trading and two-hour resumption of critical SCI systems following a wide-scale disruption. In many cases, CHX will exceed those thresholds as it currently utilizes geographically diverse datacenters in Chicago and New Jersey that allow simultaneous trading at each datacenter and provide the ability to move trading in all securities to either datacenter within minutes.

The Plan also contemplates strategies and contingencies to mitigate disruption, failure or loss of many aspects of CHX systems including, but not limited to, data backup and recovery; all mission critical systems; alternative communications with Participants, employees and regulators; alternate physical location of employees; and regulatory reporting functions.

CHX reviews the Plan on an annual basis and participates in the annual Securities Industry and Financial Markets Association (SIFMA) industry-wide business continuity test as well as the quarterly Security Information Processor (SIP) failover tests. CHX encourages its Participants to participate in the annual SIFMA BCP test.
