For the purposes of revaluing on repayment NS&I Index-linked Savings Certificates (Retirement Issue, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th and 9th Index-linked Issues) the Index figure issued by the Office for National Statistics in the month of October 2013 for the month of September 2013, and applicable to the month of November 2013 is 251.9 . This figure is based on the revised reference base of 100 adopted in January 1987. In accordance with the relevant prospectuses a Notional Index figure of 993.7 has been calculated and will apply to Index-linked Savings Certificates purchased in March 1987 or earlier.

Note that this is the last time NS&I will issue this notice. On 11 November 2013 we changed the way we calculate the index-linking on the above older Issues of Index-linked Savings Certificates, in line with how we calculate index-linking on all other, more recent Issues. The changes mean that we no longer need to use the revised reference base and the Notional Index figure. We have already written to affected customers to explain the changes, but anyone wanting more information can visit nsandi.com or call us on 0500 007 007. Calls may be recorded.
