The average annual return on the sale of equity in UK PPP project companies was 29% between 1998-2012 - twice the 12%-15% rate of return in PPP business cases at financial close of projects. PPP equity was sold an average of 6 years after the financial close of the project. The annual return for infrastructure investment is significantly higher than the annual return for shares, bonds and property investment.
Twelve PPP projects had an annual rate of return of over 100% and another 25 had an annual rate of return of between 50%-100%. PPP profits remain unregulated with no profit sharing with the public sector. The excess profit could be £2.65bn, all of which benefits private sector companies.
