Additional information in relation to BT’s Current Cost Financial Statements for 2013 In the Current Cost Financial Statements for 2013 published on 31 July 2013 (the “Statements”), we restated, where practicable, the prior year comparative figures to ensure consistency with methodologies used for the current year. Since publication of the Statements, we have identified a typographical error in Section 6.4 Attribution of Wholesale Current Cost Mean Capital Employed 2012 (Annex 6A) on page 29 of the Statements. We have found that the disaggregation of the total mean capital employed between the different asset and liability categories was incorrectly shown for Wholesale broadband access (WBA) Market 1 and WBA Market 2. The counter side of these errors was reflected in the asset and liability classification within the Wholesale Residual market and so the total assets by asset category is correct, notwithstanding the error. This error is restricted to the restated information for the year ended 31 March 2012 for those markets described above in Section 6.4 only and does not impact any other section or annex of the Statements. The additional information published here shows Section 6.4 of the Statements after correction of the typographical error described above. This information is a supplement to the published Statements, not a revision of them. Consequently, the published Statements, together with the related report of the independent auditors, remain in issue.
