In 1992, SBC acquired O'Connor & Associates, a Chicago-based options trading firm and the largest market maker in the financial options exchanges in the U.S.[76] O'Connor was combined with SBC's money market, capital market, and currency market activities to form a globally integrated capital markets and treasury operation.[76] In 1994, SBC acquired Brinson Partners, an asset management firm focused on providing access for U.S. institutions to global markets, for US$750 million.[77] Following the acquisition, founder Gary P. Brinson ran SBC's asset management business and later when SBC merged with UBS was named chief investment officer of UBS Asset Management.[78] The acquisition of S.G. Warburg & Co., a leading British investment banking firm, in 1995 for the price of US$1.4 billion signified a major push into investment banking.
