Burlington (Vt.) Employees' Retirement System launched an invitation-only search for a manager to run $24 million in active domestic core or core-plus bonds, according to William S. Wick, financial adviser at Morgan Stanley, investment consultant to the $97 million system. Funding will come from a manager that is being terminated, but he declined to identify the firm. Mr. Wick and Ron Biedermann, another Morgan Stanley adviser, are handling the search. Proposals are due April 22. Cindy Davis, retirement administrator, said some information reported about the search by another newsletter was incorrect.
