Mission-related investments may take the following forms:

• Program-related investments, typically low-interest senior or subordinated loans or equity-like investments to nonprofit or for-profit organizations whose work closely corresponds with the Foundation’s programmatic interests;
• Market-rate insured deposits in low-income designated credit unions or community development banks;
• Other mission-related investments including, but not limited to, private equity and fixed-income securities offering a risk-adjusted market rate of return with substantial social benefits to low-income families and communities.
