Structure of cash and cash equivalents
The decrease in the value of bank deposits with a maturity of up to 3 months was attributable mainly to the repayment of liabilities on account of the purchase of non-financial non-current assets. Detailed information in this respect is presented in the consolidated statement of cash flows. The Group estimated the provisions for cash and deposits, based on the probability of default, determined using external ratings of banks keeping the cash / deposits and publicly available information from credit rating agencies on the probability of default. The Group chose not to recognize an impairment loss due to its immateriality. Restricted cash included mostly cash accumulated on bank accounts kept for tender deposits, guarantees and the split-payment mechanism.
