New York City Retirement Systems extended the deadline for proposals in its search for managers of debt-based economically targeted investment programs to May 1 at 4 p.m. EDT, from April 17, said Jane Levine, deputy comptroller for pensions. The mandate, the amount of which is undetermined, will be funded from fixed income. The system is looking for investments that focus on low- and moderate-income communities in one or more of New Yorks five boroughs and provide a market rate of return. They can include loans for rehabilitation or new construction of residential, mixed-use, commercial or community facilities. Interested managers should contact Noreen Pye at (212) 669-4949, or select NYC Pension Funds at the systems website, www.comptroller.nyc.com.
