As of the date of publication of the consolidated financial statements, there has been no material damage and outage in the core network and around 10% of base stations temporarily down on average on daily basis due to energy cut-offs whereas around 60% of the stores are open nationwide on daily average as of the end of the March. The portion of telecommunication equipment and revenue earned in the currently invaded region by Russia compared to our total telecommunication equipment and our total revenue earned in Ukraine is insignificant. Since the banking systems continue to operate within the country and liquidity is mostly kept at creditor banks, cash position is conducive to sustain the operations. The Group management considers this invasion to be a non-adjusting post balance sheet event and according to the assessments of the Group management, the invasion does not have any effect on the ability of the going concern of the Group. The Group has no way to predict the progress or outcome of the situation as the conflict and government reactions are rapidly developing and beyond the Group’s control. Prolonged unrest or military activities may impact the Group’s financial condition, results of operations and cash flows.
