A U.S. unit of Prudential P.L.C., London, is trying to do more to support nonprofit groups in areas where it has large offices.

Jackson National Life Insurance Company, Lansing, Mich., says it will contribute a portion of its annual pretax profits for community investment activities through a new Jackson National Community Fund.

The fund will give at least $2 million over the next 3 years to community-enrichment programs, colleges and charitable organizations that help children and older people in Chicago, Denver, Lansing and Santa Monica, Calif., according to Jackson National.
