The human resources consulting firm occupies all four buildings at 90, 98 and 100 Half Day Rd. (Route 22), as well as 4 Overlook Point. The buildings were constructed from 1974 to 1996. Inland Western Retail Real Estate Trust says in a recently filed prospectus that it used a $129.8-million, 25-year, interest-only loan at 5.04% to buy the sprawling office campus, which was owned by FORE Holdings, LLC, an entity related to Hewitt Associates.

The acquisition is the largest in a recent round of 11 buys by the fast-growing REIT, which continues to buy properties east of the Mississippi River as well as outside the retail sector. The next-largest acquisition is 507,615-sf center in Williston, VT, anchored by Shaw's Supermarket, which the REIT picked up for $102.3 million.

According to its own Securities and Exchange Commission filing, Hewitt Associates will pay $1.26 million a month in base rent under a new lease for its Lincolnshire space, which is on about 86 acres. That equates to a deal at a 6.87% capitalization rate, as well as a new rental rate of $13 per sf under a lease that runs into 2020.
