An executive at the investment giant TPG who was charged in a huge college admissions scandal introduced colleagues on the firm’s deal team to the scheme’s ringleader, but nothing came of the business discussions, TPG said on Thursday.

TPG also said it planned to strip the executive, William E. McGlashan Jr., of most of the profits he was due from funds he oversaw.

The disclosures, in a memorandum to employees, followed an internal investigation into Mr. McGlashan, whom TPG said it had fired last month after he was implicated in the admissions scheme. (Mr. McGlashan has insisted that he resigned before he was fired.)

Federal prosecutors have accused Mr. McGlashan, one of TPG’s biggest stars and a powerful Silicon Valley investor, with paying $50,000 to a charity run by the businessman William Singer in exchange for getting his son extra time to complete a college-entrance exam. He is also accused of agreeing to pay $250,000 to ensure his son’s admission to the University of Southern California as a football recruit, although prosecutors have said he did not follow through with that scheme.
