5.Segment reporting

The Group’s Executive Committee is identified as the chief operating decision maker (“CODM”) that reviews the Company’s internal reporting to assess performance and allocate resources. Management has determined the operating segments based on these reports.

The CODM has identified three reportable and operating segments:

●

Nigeria;

●

SSA; and

●

Latam (discontinued operations – see note 21)

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (CONTINUED)

The CODM primarily uses a measure of Adjusted EBITDA (including by segment) as income/(loss) for the period, before income tax expense/(benefit), finance costs and income, depreciation and amortization, net (reversal of impairment)/ impairment of withholding tax receivables, impairment of goodwill, business combination transaction costs, net impairment/(reversal of impairment) of property, plant and equipment, right-of-use assets, intangible assets excluding goodwill and related prepaid land rent, reversal of provision for decommissioning costs, net (gain)/loss on disposal of property, plant and equipment and right-of-use assets, share-based payment (credit)/expense, insurance claims, gain on disposal of subsidiary and certain other items that management believes are not indicative of the core performance of our business. The most directly comparable IFRS measure to Adjusted EBITDA is our income/(loss) for the period. The CODM also regularly receives information about the Group’s revenue by segment. The Group has additional corporate costs which do not meet the quantitative thresholds to be separately reported and therefore are not allocated to operating segments. Segment Adjusted EBITDA represents Adjusted EBITDA excluding unallocated corporate expenses.

There are no revenue transactions which occur between operating segments. Intercompany finance income, finance costs and loans are not included in the amounts below.

The additions to property, plant and equipment, right-of-use assets, and intangible assets within segment assets are based on the operations of the segment and the physical location of the assets, and are measured in the same way as in the consolidated financial statements.

Summarized financial information is as follows:
