Omidyar’s rank of 47 on list of rich a drop from last year

Hawaii’s philanthropic powerhouse Pierre Omidyar fell to No. 47 on the Forbes 400 list of the richest people in America.

The 43-year-old self-made billionaire-turned-philanthropist is worth $5.5 billion, the same as last year, when he ranked No. 40 on the Forbes list.

Omidyar, who lives in Hawaii with his wife, Pam, and three children, has donated a significant part of his fortune to local nonprofit groups.

Earlier this month, Omidyar said he planned to infuse Hawaii projects with more cash through his Ulupono Initiative, which promotes food sustainability, renewable energy and waste reduction.

Last year the Omidyars pledged $50 million over six years to the Hawaii Community Foundation, a charitable services and grant-making organization.

“Through the Ulupono Initiative and Hawaii Community Foundation, what he and Pam are trying to do is find ways to provide opportunities for people in Hawaii to improve their quality of life,” said Sarah Steven, spokeswoman for the Omidyar family.
