REUTERS\/Brendan McDermid(Reuters) - The figure at the center of the U.S. college cheating scandal spoke twice in the past decade at events hosted by Pacific Investment Management Co (Pimco), one of the world\u2019s largest asset managers whose former chief executive is ensnared in the fraud, the company said on Friday. Some Pimco employees also used William \u2018Rick\u2019 Singer\u2019s \u201clegitimate college prep services,\u201d Pimco said in a statement. \u201cWe have no information at this time, however, to indicate Pimco employees acted improperly in their private capacity,\u201d Pimco said. \u201cAny such relationships with Mr. Singer are entirely the private affairs of individuals. However, Pimco holds its employees to the highest ethical standards, so any employee\u00a0found to have engaged in fraud or any illegal activity would have no place at the firm,\u201d the firm said. Singer, who last addressed a Pimco event in 2015, is accused by federal authorities of bribing athletic coaches and arranging for phony test-takers to secure clients\u2019 children spots at elite universities. One of the parents accused of paying Singer in the alleged scheme is Douglas Hodge, Pimco\u2019s former CEO, who left the company in 2017.
