HIGHLIGHTS – HALF-YEAR 2018 ADOPTION OF THE NEW IFRS 9 AND IFRS 15 STANDARDS On November 22, 2016, EU Regulation No. 2016/2067 was issued, which adopted IFRS 9 (Financial Instruments) at EU level, relating to the classification, measurement, derecognition and impairment of financial assets and liabilities. As permitted by IFRS 9, the TIM Group has opted to defer the application of the hedge accounting model and to continue applying the provisions of IAS 39, deciding not to restate figures for comparative periods before the first-time application. The different classification of financial assets had no substantial impact for the TIM Group on the measurement of those assets, while the introduction of the expected credit loss model, replacing the incurred loss model required by IAS 39, resulted only in a negligible reduction in consolidated equity at the transition date of January 1, 2018. On September 22, 2016, EU Regulation No. 2016/1905 was issued, which adopted IFRS 15 (Revenues from contracts with customers) and the related amendments at EU level. On October 31, 2017, clarifications to IFRS 15 were adopted through EU Regulation No. 2017/1987. IFRS 15 replaces the standards that formerly governed revenue recognition, namely IAS 18 (Revenue), IAS 11 (Construction contracts) and the related interpretations on revenue recognition (IFRIC 13 Customer loyalty programmes, IFRIC 15 Agreements for the construction of real estate, IFRIC 18 Transfers of assets from customers and SIC 31 Revenue – Barter transactions involving advertising services). The TIM Group has applied the modified retrospective method with the recognition of the cumulative effect of the first-time application of the standard as an adjustment to the opening balance of equity for the period when the standard is adopted, without restating prior periods. The comprehensive net impact (including tax effects) of the adoption of IFRS 15 on consolidated equity at January 1, 2018 (transition date) was not material and mainly connected with the combined effects of: . the change in the types of contract costs that are deferred; . the new approach to recognizing activation/installation revenues and the recognition of contract assets connected with the earlier recognition of revenues from bundle offers. Further details are provided in the Note “Accounting Policies” to the Half-year Condensed Consolidated Financial Statements at June 30, 2018 of the TIM Group. To enable the year-on-year comparison of the economic and financial performance for the first half of 2018, this Interim Management Report also shows “comparable” financial position figures and “comparable” income statement figures, prepared in accordance with the previous accounting standards applied (IAS 39, IAS 18, IAS 11, and relative Interpretations). FINANCIAL HIGHLIGHTS In terms of economic and financial performance, for the first half of 2018: . Consolidated revenues amounted to 9,441 million euros; comparable consolidated revenues totaled 9,512 million euros, down by 2.7% on the first half of 2017, mainly as a result of the significant devaluation of the Brazilian real which reduced the contribution of Tim Brasil to consolidated revenues in euro; in organic terms the Group’s consolidated revenues increased 1.5%. Consolidated revenues for the second quarter of 2018 amounted to 4,732 million euros. The comparable figure shows a drop of 3.7% (+0.4% in organic terms). EBITDA amounted to 3,763 million euros; comparable EBITDA totaled 3,918 million euros, down by 4.8% on the first half of 2017 (-1.6% in organic terms), with an EBITDA margin of 41.2%, -0.9 percentage points on the figure for the first half of 2017 (41.2% in organic terms, -1.3 percentage points). EBITDA in the first half of 2018 was pulled down by a total of 121 million euros in non-recurring expenses (56 million euros in the first half of 2017, at constant exchange rates, and including certain “one-off” items), without which the organic change would have been a positive 2 million
