[1] As of June 30, 2021 and 2020, the Company entered into certain contracts with customers (state-owned entities) where the Company’s services included freight costs and cost of commodities to be shipped to customers’ designated locations. The Company prepaid the costs of commodities and recognized as advance payments on behalf of its customers. These advance payments on behalf of the customers will be repaid to the Company when either the contract terms are expired or the contracts are terminated by the Company. As aforementioned customers were negatively impacted by the pandemic and required additional time to execute existing contracts, they required additional time to pay. Due to significant uncertainty on whether the delayed contracts will be executed timely. As such, the Company had provided an allowance due to contract delay and recorded allowances of approximately $10.0 million for the year ended June 30, 2020. For the year ended June 30, 2021, the Company recovered $4,786,814 of the reserved amount.
