The board of Detroit's General Retirement System yesterday approved economic terms of a settlement with the city that include cuts to pension benefits, putting in place another key component of Detroit's effort to exit bankruptcy by October, Reuters reported yesterday. The city also has reached a tentative pact with the city's other pension fund, the Detroit Police and Fire Retirement System, whose board is expected to vote later this week. Together, the two pension funds represent some 23,000 active members and retirees.
