The designation comes after last year's sale of NAI's previous affiliate and an in-depth search to find a replacement. "We are delighted with the result," Finn tells GlobeSt.com. "This is an ideal fit for us." NAI was enticed by the broad nature of Erinaceous' capabilities and the firm's geographic reach, says Finn.

Founded just eight years ago, Erinaceous has 50 UK offices and 5,000 staffers offering expertise in everything from asset management and development to leasing, property management and investment sales. The latter arena, says Finn, was "a particular strength" of Erinaceous piquing his organization's interest, with NAI seeking to increase its production in that field. About 25% of NAI Global's 2006 revenues of $40 billion was generated from investment sales, Finn estimates, and Erinaceous principal Stuart Hicks says his company is eager to expand that line as well.

According to Hicks, managing director for the Professional Services Group, just about everything in NAI's UK platform fits with his firm's outlook as well, including a desire to be an industry leader. "We have a very clear and determined intention to break into the top five firms in the UK," says Hicks, the same ranking NAI hopes to achieve in the major world markets it operates. As it was, he tells GlobeSt.com, the recent ascension to the eighth spot in a UK survey was "a great surprise" to the industry, especially given the presence of several stalwarts in business for more than a century.
