3i Infrastructure plc - Pre-close update

3i Infrastructure plc ("3i Infrastructure" or "the Company") announces its trading update ahead of the close period for the six months ending 30 September 2012. The data in this statement relates to the period from 1 April 2012 to 26 September 2012.

Peter Sedgwick, Chairman of 3i Infrastructure, said: "The Company's European assets continue to perform well, while adverse macroeconomic conditions and foreign exchange movements continue to have a negative impact on the valuation of the 3i India Infrastructure Fund. The Investment Adviser continues to develop the pipeline of opportunities and has made good progress in the Thameslink transaction."

Investment and realisation activity

3i Infrastructure invested £4.9 million in a portfolio of road BOT companies of Supreme Infrastructure India Limited through the 3i India Infrastructure Fund, a transaction described in more detail in the Company's latest Interim Management Statement, dated 10 July 2012. There was no realisation activity in the period, however the Company received proceeds of £6.6 million from Eversholt Rail Group from the partial repayment of a shareholder loan.

Portfolio and returns

The Company's European portfolio continues to perform well operationally and financially. The portfolio generated income of £30.8 million in the period (£36.8 million in the equivalent period last year), with the decline attributable principally to the lower dividend received from AWG, as described in our latest Interim Management Statement referred to above.

The mark-to-market valuation of Adani Power Limited and the exchange rate between sterling and the Indian rupee were broadly unchanged on 26 September 2012 compared to the position disclosed in the latest Interim Management Statement.

As usual, an important element of the determination of the Company's results for the six months to 30 September 2012 will be the valuation exercise carried out on the investment portfolio as at that date. 3i Infrastructure expects to announce its half yearly results on8 November 2012.

Balance sheet

At 26 September 2012 the Company had cash balances of £169.7 million, up from £144.2 million reported in the latest Interim Management Statement, reflecting the investment activity, income and proceeds received and costs paid in the period.
