The transfer of open interest was accomplished through both central order book transactions and block trades.

NYSE Liffe US said it will not impose any additional fees or surcharges on block trading activity.

NYSE Liffe US CEO Thomas Callahan said they appreciate the strong support of their customers during the migration of the MSCI Pan-Euro Index-linked futures.

"We are committed to building a liquid, vibrant market for futures based on MSCI indices and consolidating open interest into our mini MSCI Pan-Euro Index contracts is part of that core strategy.

"The next step will be migrating futures on the MSCI Emerging Markets and MSCI EAFE indices from the CME in June. We have been proactively working with our extensive global client base to ensure a seamless transition of the over 65,000 lots of open interest in these contracts," Callahan said.
