Keith Dorrian, Chairman of International Public Partnerships Limited, commented:

"The Company and our shareholders continue to benefit from the opportunities arising from the renewed commitment shown by governments to infrastructure investment across our geographies.

There is a heightened awareness of the pivotal role private capital plays in these long-term public sector programmes, resulting in a surge in interest from an increasingly wide investor base, attracted by the risk reward profile of the Company and asset class.

Taking advantage of the positive investment environment through our healthy pipeline of attractive investment opportunities is critical to the ongoing success of the Company and as such, we are actively considering our options with respect to raising more equity capital.

We look forward to 2012 with confidence."
