This Order specifies 2.7 per cent. as the percentage by which that part of any guaranteed minimum pension attributable to earnings factors for the tax years 1988-89 to 1996-97 and payable by contracted-out, defined benefit occupational pension schemes is to be increased. Under section 109(3) of the Pension Schemes Act 1993 (c.48) the percentage to be specified is the actual percentage increase in the general level of prices in the period under review or 3 per cent., whichever is less.
