3i Infrastructure Limited - Interim Management Statement



17 August 2007



3i Infrastructure Limited ('3i Infrastructure') is an investment company
focusing on infrastructure investment opportunities globally. This is the first
Interim Management Statement issued by 3i Infrastructure in accordance with the
FSA's disclosure and transparency rules. This statement covers the first period
of trading since flotation of the Company, that is, the period from 13 March
2007 to 16 August 2007.

Peter Sedgwick, 3i Infrastructure's Chairman, said: 'The focus of 3i
Infrastructure since the IPO has been to invest the capital raised at flotation
in assets that will help secure our target returns for the future. We have made
good progress in this respect. The assets which seeded the initial portfolio at
flotation are performing well and these have generated returns in line with our
expectations.'

Michael Queen, Infrastructure Managing Partner of 3i Investments plc -
Investment Adviser to 3i Infrastructure, commented: 'Although market conditions
remain competitive in the infrastructure asset class, we have maintained a
strong, global investment pipeline throughout this first period while building
our investment team capabilities internationally. The recent minority investment
in three of Oiltanking GmbH's subsidiaries, based in Singapore, The Netherlands
and Malta, demonstrates the benefits of our international network as well as our
ability to execute transactions across multiple geographies.'



 1. Investments



3i Infrastructure invested a total of £357m equity in the period to 16 August
2007 including the £234m acquisition of the initial portfolio from 3i Group at
flotation.



The largest investment, after the purchase of the initial portfolio in the
period was the acquisition of a 45 per cent interest in three Oiltanking GmbH
subsidiaries - Oiltanking Singapore Limited, Oiltanking Amsterdam BV and
Oiltanking Malta Limited - which provides oil and chemical storage facilities.
The consideration for the asset comprised €115m equity from 3i Infrastructure
and €190m debt from RBC Capital Markets.



I2, the secondary market infrastructure fund acquired by 3i Infrastructure at
flotation, has continued to invest strongly, drawing down commitments of  £30m
from 3i Infrastructure during the period. The largest asset acquired by that
fund during the period was The PFI Infrastructure Company plc, a vehicle
investing in public to private partnership projects throughout the UK.



Thermal Conversion Compound Industriepark Hochst GmbH, a company established to
develop, own and operate a waste to energy plant in Germany, has been
transferred to 3i Infrastructure from 3i Group for €10m. As set out in the 3i
Infrastructure Prospectus, this investment was made by 3i Group shortly before
the flotation of 3i Infrastructure. It was not practicable to include it in the
initial portfolio of assets acquired from 3i Group at flotation but was made
available for acquisition by 3i Infrastructure after the IPO.





 2. Returns



Returns on investment for the period to 31 July 2007 are in line with our
expectations. In November 2007 3i Infrastructure will issue Interim results for
the period to 30 September 2007, including the net asset value as at 30
September 2007.



 3. Developments at Investment Adviser



The Investment Advisory team has continued to build its capabilities in the UK
and internationally and has grown the investment team, including the recruitment
of four new investment professionals, one in the UK and three in India, who are
focused on infrastructure investing. Further progress has also been made towards
the establishment of a dedicated US infrastructure team.



 4. Indian infrastructure market



An important part of 3i Infrastructure's strategy is to invest in Asian
infrastructure. 3i Group plc signed a Memorandum of Understanding with India
Infrastructure Financing Company Limited ('IIFCL') on 12 April 2007. IIFCL was
incorporated in January 2006 as a wholly government owned company for the
purpose of providing financial support to infrastructure projects and facilities
in India. Investments arising from this partnership will primarily be in power,
ports, logistics, airports and road projects in both early-stage and mature
infrastructure operations. This partnership will generate attractive
opportunities to enable 3i Infrastructure to meet its objective for investing in
Asian Infrastructure.
