Detroit's three automakers are mulling a request by the city's art museum to help it raise money for a key component of Detroit's plan to restructure its debt and exit bankruptcy, Reuters reported yesterday. Under an $816 million so-called grand bargain, the Detroit Institute of Arts would contribute $100 million to ease pension cuts on the city's retirees and avoid a sale of art works to pay city creditors. The rest of the money would come from philanthropic foundations and the state of Michigan, where a $350 million contribution over 20 years or a $195 million lump sum payment needs legislative approval.
