United Kingdom

Guy Elliott and Tom Albanese participate in the non contributory Rio Tinto Pension Fund, a funded occupational pension scheme approved by HM Revenue and Customs. The Fund provides both defined benefit and defined contribution benefits. In April 2005, the defined benefit section of the Fund was closed to new participants.

Members of the defined benefit section of the Fund who retire early may draw a pension reduced by approximately four per cent a year for each year of early payment. Spouse and dependants' pensions are also provided. Pensions paid from this section are guaranteed to increase annually in line with increases in the UK Retail Price Index subject to a maximum of ten per cent per annum. Increases above this level are discretionary.

During 2006, there was no requirement for Company cash contributions to be paid into the Rio Tinto Pension Fund.

Rio Tinto reviewed its pension policy in the light of the legislation changes introduced from April 2006. The Rio Tinto Pension Fund was amended to incorporate a fund specific limit equivalent to the earnings cap for all members previously affected; unfunded benefits continue to be provided, where already promised, on pensionable salary above the fund specific limit.

Guy Elliott is accruing a pension of 2.3 per cent of basic salary for each year of service with the Company to age 60. Proportionally lower benefits are payable on leaving service or retirement prior to the age of 60. The unfunded arrangements described above will be utilised to deliver this promise to the extent not provided by the Fund.

Rio Tinto plc exercised discretion to allow Tom Albanese to join the Rio Tinto Pension Fund as a member of the defined benefit section on 1 July 2006 in recognition of his participation in one of the US defined benefit pension arrangements offered by Rio Tinto prior to that date. He is accruing a pension of two thirds of basic salary payable at the normal retirement age of 60, subject to completion of 20 years' service with the Group, inclusive of benefits accrued under the US pension arrangements. Proportionally lower benefits are payable for shorter service or, if having attained 20 years' service, retirement is taken prior to the age of 60. His benefits under the Rio Tinto Pension Fund are restricted to the fund specific limit, with the balance provided through unfunded arrangements.
