"The Prime Minister [David Cameron] will use the UK’s presidency of the G8 this year to develop new agreements on “impact investing” where funds buy bonds with a guaranteed return if certain public policies are delivered. One of the first social impact bonds in the UK was launched three years ago to support a project to reduce re-offending by inmates at Peterborough Prison. The projects are delivered by social enterprises, not-for-profit organisations, foundations and charities.'' (Quoted from article)
