Madison Dearborn Partners (MDP) is an American private equity firm specializing in leveraged buyouts of privately held or publicly traded companies, or divisions of larger companies; recapitalizations of family-owned or closely held companies; balance sheet restructurings; acquisition financings; and growth capital investments in mature companies.
Madison Dearborn Partners was founded in 1992 and is based in Chicago, Illinois. The founders, John A Canning Jr, Paul J. Finnegan, Samuel M. Mencoff, and Nicholas W. Alexos had previously made private equity investments for First Chicago Bank. The north-east corner of First Chicago's then-headquarters was at the intersection of Madison and Dearborn Streets.
Nuveen investments; in 2014, a plan for MDP to sell Nuveen to TIAA-CREF for $6.25 billion was announced; while the Wall Street Journal cited an anonymous source close to the transaction to the effect that MDP "will have broken even on the transaction", Felix Salmon queried that assertion at Reuters; Dan Primack at Fortune then published additional information about auxiliary benefits to MDP to buttress the break-even claim.
On June 30, 2007, Bell Canada Enterprises (BCE) announced that the company entered into a definitive agreement for BCE to be acquired pursuant to a plan of arrangement by an investor group led by Teachers Private Capital, the private investment arm of the Ontario Teachers' Pension Plan, Providence Equity Partners Inc. and Madison Dearborn Partners.
