Annual Financial Report - 5 of 54

The management commentary included in the Report of the Directors: 'Financial Review', together with the 'Employees' and 'Corporate sustainability' sections of 'Corporate Governance' and the 'Directors' Remuneration Report' is presented in compliance with the IFRSs Practice Statement 'Management Commentary' issued by the IASB.

Use of non-GAAP financial measures

Our reported results are prepared in accordance with IFRSs as detailed in the Financial Statements on page 334. In measuring our performance, the financial measures that we use include those which have been derived from our reported results in order to eliminate factors which distort year-on-year comparisons. These are considered non-GAAP financial measures. The primary non-GAAP financial measure we use is 'adjusted performance'. Other non-GAAP financial measures are described and reconciled to the most relevant reported financial measure when used.

Adjusted performance

Adjusted performance is computed by adjusting reported results for the year-on-year effects of foreign currency translation differences and significant items which distort year-on-year comparisons.

Previously we used the non-GAAP financial measure of 'underlying performance', which was calculated by adjusting reported results for the year-on-year effects of currency translation differences, own credit spread and acquisitions, disposals and dilutions. In 2014, we modified our approach to better align it with the way we view our performance internally and with feedback received from investors. Adjusted performance builds on underlying performance by maintaining the adjustment for currency translation differences and incorporating the adjustments for own credit spread and acquisitions, disposals and dilutions into the definition of significant items. We use the term 'significant items' to collectively describe the group of individual adjustments which are excluded from reported results when arriving at adjusted performance. Significant items, which are detailed below, are those items which management and investors would ordinarily identify and consider separately when assessing performance in order to better understand the underlying trends in the business.

We believe adjusted performance provides useful information for investors by aligning internal and external reporting, identifying and quantifying items management believe to be significant and providing insight into how management assesses year-on-year performance.

We arrive at adjusted performance by excluding from our reported results:

·   the year-on-year effects of foreign currency translation differences. This is done by comparing reported results for 2014 with reported results for 2013 retranslated at 2014 exchange rates. The foreign currency translation differences reflect the movements of the US dollar against most major currencies; and

·   significant items which distort the year-on-year comparison of reported results by obscuring the underlying factors and trends which affect operations. Significant items include adjustments for own credit spread and acquisitions, disposals and dilutions which were previously part of our underlying measure. The following pages provide further details, including a reconciliation from reported to adjusted results.

For acquisitions, disposals and changes of ownership levels of subsidiaries, associates, joint ventures and businesses, we eliminate the gain or loss on disposal or dilution and any associated gain or loss on reclassification or impairment recognised in the year incurred, and remove the operating profit or loss of the acquired, disposed of or diluted subsidiaries, associates,
joint ventures and businesses from all the years presented so we can view results on a like-for-like basis. Disposal of strategic investments other than those included in the above definition would be included in other significant items if material.

The following acquisitions, disposals and changes to ownership levels affected adjusted performance:
