 equivalents Since cash and cash equivalents mainly consist of bank deposits, the carrying amount approximates its fair value. (b)Cash segregated as deposits Cash segregated as deposits includes cash deposited in trust accounts. The carrying amount approximates its fair value. (c)Customer accounts receivable, Other financial assets, Deposits received and Other financial liabilities The carrying amount of instruments with short -termmaturity approximates its fair value. The fair value of instruments with long -termmaturity is measured using future cash flows discounted by a rate reflecting the counterparty or the Company’s credibility, which is a reasonable approximation of the carrying amount. Derivative assets and liabilities are included in “Other financial assets” under current assets and “Other financial liabilities” under current liabilities, respectively. Derivative assets and liabilities mainly represent cryptocurrency leveraged trading with customers which are measured at the fair value using a valuation technique based on the observable prices in the crypto exchange market.
