MBTA, union face pension fund difficulties

BOSTON — Already struggling to close a structural budget deficit and improve service, the MBTA on Monday turned its attention to the drain retirees are putting on the T's pension fund.
The T's pension fund, which is overseen by board members representing unions and management, needs to achieve returns of about 6 percent to avoid losing value, according to MBTA Chief Administrator Brian Shortsleeve, who said that rate of return on investment might not be likely in future years.
