The move will help create a fully-integrated commercial property services company. The local affiliate is NAI Sullivan Group, led by Bob Sullivan.

"We are very excited about this expanded relationship and the opportunity to be a part of the worldwide presence of C-III,” Sullivan said. “This new relationship expands our ability to help local businesses and help bring global companies to Oklahoma City."

As a real estate services company, C-III is involved in primary and special loan servicing, loan origination, fund management, investment services, title services and multifamily property management. It is based in Irving, Texas, and has offices in New York, South Carolina, Virginia, Illinois and Tennessee. Despite the acquisition, C-III reported NAI Global will continue to operate as a separate company under its current management.

"The completion of this transaction represents a significant step forward in our strategy to build a fully diversified commercial real estate services company," said C-III CEO Andrew L. Farkas. "With the NAI Global acquisition, we are gaining the world's leading commercial real estate network and a tremendous foundation for future growth. As we begin a new year, we look forward to partnering with the NAI team to provide enhanced services to the commercial and institutional real estate markets they serve, as well as continuing to take advantage of other opportunities to grow and expand our platform."

NAI Global was founded in 1977 by Gerald Finn. The current president and CEO is Jeffrey M. Finn. It now has a presence in more than 350 offices in 55 countries and more than 300 million square feet of commercial space under management.
