The W.K. Kellogg Foundation has pledged $40 million to protect the Detroit Institute of Arts and the city's pensions.
The company joined a coalition of private foundations seeking to bolster Detroits pension funds and protect city-owned art from being sold off in bankruptcy.
With the Battle Creek-based foundations $40 million pledge, the fund now totals $370 million from ten regional and national foundations.
Governor Rick Snyder and Republican legislative leaders have pledged $350 million in state aid over 20 years to match the private donations.
The Kellogg Foundation is not disclosing over how many years it will spread the $40 million pledge, which is the third largest single contribution to the Detroit pension and DIA rescue fund.
