Social Impact Bond - SIB

AAA

DEFINITION of 'Social Impact Bond - SIB'

A contract with the public sector or governing authority, whereby it pays for better social outcomes in certain areas and passes on part of the savings achieved to investors. A social impact bond (SIB) is not a bond, per se, since repayment and return on investment are contingent upon the achievement of desired social outcomes; if the objectives are not achieved, investors receive neither a return nor repayment of principal. SIBs derive their name from the fact that their investors are typically those who are interested in not just the financial return on their investment, but also in its social impact.

INVESTOPEDIA EXPLAINS 'Social Impact Bond - SIB'

In 2011, Peterborough Prison in the United Kingdom issued one of the first social impact bonds anywhere in the world. The bond raised 5 million pounds from 17 social investors to fund a pilot project with the objective of reducing re-offending rates of short-term prisoners. The relapse or re-conviction rates of prisoners released from Peterborough will be compared with the relapse rates of a control group of prisoners over six years. If Peterborough's re-conviction rates are at least 7.5% below the rates of the control group, investors receive an increasing return that is directly proportional to the difference in relapse rates between the two groups and is capped at 13% annually over an eight-year period.
