3i Infrastructure plc - Pre-close update

3i Infrastructure plc ("3i Infrastructure" or "the Company") will be holding discussions with analysts and investors ahead of its close period for the six months ending 30 September 2010. This statement sets out the information for the period from 1 April 2010 to 27 September 2010 that will be covered in those discussions. 3i Infrastructure expects to announce its results for the six months ending 30 September 2010 in November 2010.

Highlights

·; Portfolio assets continue to perform well, generating strong income

·; Current cash balances of £297 million

·; Attractive pipeline of investment opportunities

Peter Sedgwick, Chairman of 3i Infrastructure, said: "3i Infrastructure's portfolio continues to generate strong income, supporting the delivery of the Company's distribution objectives."

Cressida Hogg, Managing Partner, Infrastructure, 3i Investments plc, added: "Market conditions for infrastructure investment remain relatively supportive. The Investment Adviser is working on an attractive pipeline of investment opportunities in Europe and in India."

1. Portfolio and returns

3i Infrastructure's portfolio is performing well operationally and financially, and is positioned to deliver a strong yield, underpinning the Company's distribution objectives. 

Movements in net asset value in the period will be influenced, among other factors, by the mark-to-market value of the junior debt portfolio, as well as currency movements. In the period from 1 April 2010, the mark-to-market valuation for junior debt instruments has remained broadly flat. Sterling has appreciated against both the euro and the US dollar in the period, resulting in a net currency loss on the unhedged foreign currency element of the portfolio.

As usual, an important element of the determination of the results for the six months to 30 September 2010 will be the valuation exercise carried out on the investment portfolio as at that date. The Company will be reporting its results for the six months to 30 September 2010, including its netasset value as at that date, in November.

2. Balance sheet

At 27 September 2010 the Company had cash balances of £297 million. There are currently no external borrowings on a recourse basis to the Company.
