The foundation was founded in 1981 as the philanthropic arm of one of the nation’s leading insurance companies. It seeks to improve community health and well-being through support of nonprofits that promote healthy behaviors, health education, and access to health services.

With nearly $180 million in assets, it is the fourth-largest foundation in Louisville. In 2014, according to its most recent annual IRS tax return, the five recipients receiving the most money were:

• KaBOOM! of Washington, D.C.: $1 million
• University of Louisville Foundation: $905,000
• Scholarship America of Minneapolis: $730,000
• Metro United Way: $707,000
• Actors Theatre: $703,000

While it’s legally separate from the insurance giant itself, their leadership overlaps. The foundation’s five directors are Humana CEO Bruce Broussard; General Counsel Christopher Todoroff; board member David A. Jones Jr.; his father, company co-founder David A. Jones Sr., and Chairman Michael McCallister, a retired Humana CEO and former chairman.

But it’s unclear whether its leadership and philanthropic focus will change under a proposed $37 billion sale to Aetna of Hartford.
