This document discusses social impact bonds and how they work. Social impact bonds allow investors to fund social service organizations working with a target population. If the organizations deliver positive social outcomes, the government pays investors based on the results. This provides funding for interventions while transferring performance risk from the government to investors. The six key steps are: 1) government and investors sign a contract setting payment amounts per outcome, 2) investors provide funding based on the contract, 3) funding is used by social service organizations to work with those in need, 4) the organizations deliver services to improve outcomes, 5) positive outcomes are achieved benefiting society and reducing government costs, 6) the government pays investors based on results achieved.
