Dear Mr Leaton 
Freedom of Information Act 
Thank you for your e-mail of 23 November 2009 in which you requested information about 
the discount rate used to calculate the present value of liabilities in respect of state employee 
pensions and the state pension, and how the discount rate was established.  
Discount rates – Public Sector workers’ pensions 
The most recently published information concerns the total accrued liability of the Pay-As-
You-Go public service occupational pension schemes as reported in published accounts as 
at 31 March 2008, estimated by the Government Actuary’s Department (GAD) to have been 
£770 billion1.  The discount rates used are disclosed in the published accounts.  The 
rationale underlying these discount rates was published in a previous Long-term public 
finance report, as follows: 
The key actuarial assumptions used to value the liabilities of individual schemes are 
set out in the relevant reports by the scheme actuary and have been reported in 
scheme resource accounts using the FRS17 accounting methodology, applied in 
accordance with guidance approved by the Financial Reporting Advisory Board 
(FRAB) for pension schemes funded directly by central Government; or the Chartered 
Institute of Public Finance and Accountancy (CIPFA) for the pension schemes for 
police and firefighters.2
The resource accounts of central government Pay-As-You-Go public service pension 
schemes are available from TSO3.  The FRS17 is available from the Accounting Standards 
Board website4.  The guidance approved by the Financial Reporting Advisory Board and 
associated documents are available from the HM Treasury website5
Discount rates – State pensions 
In my letter of 20 November 2009 we disclosed that as at 31 March 2005, and based on the 
legislation then in force, the value of accrued rights to basic state pension was £1,020 billion 
and the value of accrued rights to additional pension, net of amounts given up as a result of

contracting out, was £330 billion.  We also explained that the discount rate used in the 
calculation was 3.5% a year over price inflation, consistent with the rate used for pension 
liabilities in Government resource accounts as at 31 March 2005. 
On a point of detail, it might be helpful to mention that the above figures relate to rights built 
up in the National Insurance Fund in Great Britain, Northern Ireland having separate 
arrangements in this regard.
