Commented Thomas P. Gallagher, Chairman and Chief Executive Officer of MIH, “We have and continue to work constructively with the SEC Staff on our proposed rule filing. In response to discussions with SEC Staff, we recently amended the filing to make minor non-substantive changes, align our market-wide circuit breaker rules with changes recently made by other equity exchanges, and to provide market participants greater specificity regarding order processing in our rules as we work toward our September 25, 2020 launch.”
