Accounts receivables are primarily due from the customers - real estate developers and are recognized and carried at the amount billed to a customer, net of allowance for doubtful accounts, which is an estimate for credit losses based on a review of all outstanding amounts on a periodic basis. The Company maintains an allowance for doubtful accounts which requires significant judgments by management. The Company establishes a provision for doubtful accounts receivable when there is objective evidence that the Company may not be able to collect the receivables when due. The allowance is based on management’s best estimates of specific losses on individual exposures, as well as a provision on historical trends of collections. Based on customers’ credit, business, financial status, payment history, and ongoing relationship, management makes conclusions on whether any balances outstanding at the end of each reporting period will be deemed uncollectible on an individual basis and on an aging trend analysis basis. Accounts receivable balances are written off against the allowance for doubtful accounts after management has determined that the likelihood of collection is not probable.
