So we actually realize more synergies this year and we're well on track for achieving the $50 million run rate synergies by the end of this year and that's net of, as I mentioned previously, we do have a double carry in terms of infrastructures, where we have a, the NEX legacy infrastructure as well as the Globex infrastructure running in parallel in anticipation of that migration of BrokerTec in and EBS. So really as Terry indicated in his prepared remarks. very, very pleased with the way the integration has been going and really excited about kind of the future of our business with NEX.
