Financial statements | Additional financial information Alternative performance measures

The Group presents certain alternative performance measures (non-IFRS measures) which are reconciled to directly comparable IFRS financial measures below. These non-IFRS measures, hereinafter referred to as alternative performance measures (APMs), are used by management to assess the performance of the business and provide additional information, which investors may find useful. APMs are presented in order to give further insight into the underlying business performance of the Group's operations. APMs are not consistently defined and calculated by all companies, including those in the Group’s industry. Accordingly, these measures used by the Group may not be comparable with similarly titled measures and disclosures made by other companies. Consequently, these APMs should not be regarded as a substitute for the IFRS measures and should be considered supplementary to those measures. The following tables present the Group's key financial measures not defined according to IFRS and a reconciliation between those APMs and their nearest respective IFRS measures. Reconciliation of APMs to the nearest comparable IFRS financial measures for the year 2021 and 2020 can be found in the section APM of our 2021 Annual Report . Reconciliation of underlying return on capital employed and Net (debt)/cash for the year 2022 can be found in our 2022 Annual Report . APMs derived from the income statement The following income statement measures are used by the Group to provide greater understanding of the underlying business performance of its operations and to enhance comparability of reporting periods. They indicate the underlying commercial and operating performance of our assets including revenue generation, productivity and cost management. Segmental revenue Segmental revenue includes consolidated sales revenue plus the equivalent sales revenue of equity accounted units (EAUs) in proportion to our equity interest (after adjusting for sales to/from subsidiaries). The reconciliation can be found in “Our financial performance” on page 167 . Underlying EBITDA Underlying EBITDA represents profit before taxation, net finance items, depreciation and amortisation adjusted to exclude the EBITDA impact of items that do not reflect the underlying performance of our reportable segments. The reconciliation of profit after tax to underlying EBITDA can be found in “Our financial performance” on page 168 . Underlying EBITDA margin Underlying EBITDA margin is defined as Group underlying EBITDA
