Revenue Recognition Most of the Company's revenue is derived from real estate sales in the PRC. The majority of the Company's contracts contain a single performance obligation involving significant real estate development activities that are performed together to deliver a real estate property to customers. Revenues arising from real estate sales are recognized when or as the control of the asset is transferred to the customer. The control of the asset may transfer over time or at a point in time. For the sales of individual condominium units in a real estate development project, the Company has an enforceable right to payment for performance completed to date, revenue is recognized over time by measuring the progress towards complete satisfaction of that performance obligation. Otherwise, revenue is recognized at a point in time when the customer obtains control of the asset. All revenues represent gross revenues less sales and business tax. ASC 606 requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASC 606 creates a five-step model that requires entities to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue when each performance obligation is satisfied. ASC 606 also specifies the accounting for the incremental costs of obtaining a contract and the costs directly related to fulfilling a contract. In addition, ASC 606 requires extensive disclosures. The Company adopted ASC 606 on January 1, 2018 using the modified retrospective approach with no restatement of comparative periods and no cumulative-effect adjustment to retained earnings recognized as of the date of adoption. A significant portion of the Company's revenue is derived from development and sales of condominium real estate property in the PRC, with revenue previously recognized using the percentage of completion method. Under the new standard, to recognize revenue over time similar to the percentage of completion method, contractual provisions need to provide the Company with an enforceable right to payment and the Company has no alternative use of the asset. Historically, all contracts executed contained an enforceable right to home purchase payments and the Company had no alternative use of assets, therefore, the adoption of ASC 606 did not have a material impact on the Company's consolidated financial statements.
