 the crypto assets. In addition, information technology (IT) professionals with specialized skills and knowledge were needed to assist in the performance of certain audit procedures. F-2 The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgment in determining the nature and extent of audit evidence required, especially in relation to the assessment of the existence of, and the Company’s rights related to, the crypto assets held in cold wallets. We involved IT professionals with specialized skills and knowledge who assisted in: •evaluating the design of certain internal controls over the existence of, and the Company’s rights related to, crypto assets held in cold wallets, as well as testing the operating effectiveness of certain of these controls. This included controls related to access management, segregation of duties across certain processes connected with the holding of crypto assets in cold wallets, and management’s reconciliation of internal records to external blockchains; •testing the existence of crypto assets by comparing the Company’s records of certain crypto assets held by the Company for its own account and certain crypto assets held for customers to the records on public blockchains using software audit tools; and •assessing the Company’s control of the private keys required to access the crypto assets held in cold wallets by observing the movement of crypto assets in the blockchain and in the Company’s internal records for a selection of crypto asset transactions. We evaluated the sufficiency and appropriateness of audit evidence obtained by assessing the results of procedures performed over the existence of, and the Company’s rights related to, crypto assets held in cold wallets. /s/ KPMG AZSA LLC We have served as the Company’s auditor since 2018.
