Callahan Capital Partners, a global investment company and Oak Hill Advisors, a private equity company, completed the acquisition of 110 North Wacker Drive, a Class-A office tower in Chicago, from The Howard Hughes, a company which owns, manages, and develops commercial, residential, and mixed-use real estate, for $210m. "The sale of 110 North Wacker Drive is a meaningful step in the execution of HHC's non-core asset dispositions. The sale generates significant net proceeds, which we will reinvest back into new developments and use to repurchase shares as part of our stock buyback program," David R. O'Reilly, Howard Hughes Chief Executive Officer.
