Ryan Labs has ramped up an additional $800 million in new business in the last few months and has been expanding its New York asset management group, said Mike Donelan, portfolio manager of the now around $19 billion investment-grade fixed-income fund. Donelan recently brought on David Maurice, formerly a portfolio manager at Utendahl Capital Management, as portfolio manager as part of the group's expansion. Maurice did not return a call. Donelan said he is not looking to make any specific additional hires at the moment, but expects to expand further going forward.
