Luther Ragin, President and CEO of the GIIN and former CIO of the F.B. Heron Foundation, argues that impact investing meets financial and philanthropic expectations.

"Is impact investing - investing with the aim of generating tangible social and environmental benefits alongside a financial return - a viable strategy? The practice has its skeptics, but even the unconvinced must recognise the growing list of successful investments and initiatives that point squarely at a burgeoning marketplace."
