Other News Announcements:

MIH is pleased to announce that through its partnership with Advanced Fundamentals, LLC (Advanced Fundamentals), an owner and developer of next generation beta indexes, the MIAX Exchange Group will list and trade a suite of proprietary options products based on five commercial real estate indexes developed by Advanced Fundamentals (CRE Indexes), following proposed rules becoming effective with the SEC on April 29, 2020. The first tranche of products, cash-settled options on the CRE Indexes, is expected to launch in the second half of 2020 and will be available exclusively on the MIAX Exchange Group. Cash-settled futures on the CRE Indexes are expected to follow, subject to CFTC approval. Additional information will be made available at a later date.

The CRE Indexes are comprised of four sector-based indexes (Residential, Retail, Office, Hospitality) and a Composite Index that measure real-time real estate returns to support hedging, benchmarking, and portfolio allocation strategies for both public and private real estate investors. The pricing of the CRE Indexes uses real-time public market data that aggregates over $600 billion in property values, measuring unlevered returns in commodity pricing such as price per square foot, price per key, and price per unit. The CRE Indexes are currently being calculated and published by Refinitiv under the symbols MXAFR (Residential), MXAFO (Office), MXAFT (Retail), MXAFH (Hospitality) and MXAFC (Composite).

The CRE Indexes are the first family of real estate indexes to incorporate commodity pricing to overcome the limitations of appraisal lag, self-reporting, and leverage disparities to establish an accurate view of the real estate market. The performance of the CRE Indexes is calculated on an unlevered basis using publicly traded equities, resulting in a 12-month leading correlation to established private market real estate indexes that rely on survey, transaction, or appraisal data.

Said John Smollen, Executive Vice President – Head of Exchange Traded Products and Strategic Relations at MIH, “There is a tremendous amount of uncertainty and disruption that the COVID-19 pandemic continues to bring to the real estate sector. Given this current environment, we believe these products could not be coming to market at a better time and will enable real estate investors the ability to better hedge their risk exposure.”

Added Joseph W. Ferraro III, Senior Vice President, Deputy General Counsel of MIH, “We would like to thank the SEC staff for its assistance in the rule review process for these proprietary products. We have developed a regulatory framework and now have the technology infrastructure in place that will allow us to rapidly deploy a number of proprietary products that we have in our pipeline.”
