Dearborn Heights (Mich.) Police & Fire Pension Plan is adding $8 million to its active domestic large-cap equities allocation, increasing it to 49.7% of total assets from 42.4%, said John Riley II, secretary. The $111 million plan will split the increase between growth and value. Funding will come from reducing the fixed-income allocation to 33.6% of total assets, said Mr. Riley. There will be no other changes to the portfolios at this time. Changes were made at the suggestion of consultant PaineWebber, said Mr. Riley.
