This document discusses changes to TIM Group's financial reporting for 2019. It introduces the adoption of new accounting standards IFRS 16 and an "After Lease" view of key financial metrics from January 2019 onward. IFRS 16 requires lease agreements to be recognized on the balance sheet as assets and liabilities, impacting reported EBITDA and net debt. The "After Lease" view reclassifies all leases as operating expenses for comparability. The document also outlines a new revenues reporting structure separating retail, wholesale, and equipment sales.
