'How much is your financial return discounted by your mission investment strategy?' We cannot tell you how many times we have heard that question. You might say we ask for it. The F B Heron Foundation has been an early adopter of strategies to invest 'endowment' funds in enterprises that offer both mission and financial returns. Today we seek to deploy all of our capital for mission, and we'd like other private foundations to do the same. But we face this mission investing discount question everywhere and all the time — after every presentation, during every interview, at every board meeting.
