[1] As of September 30, 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. The management reassessed the collectability of such advance payments and decided to recover of approximately $5.1 million of allowance for the three months ended September 30, 2020. As of September 2020, the Company has allowances for doubtful accounts due to contract delay of approximately $5.2 million.
