The Company’s revenues consist primarily of 1) buildout of the remaining projects under the homebuilding platform, 2) recurring fees earned under the AMA, 3) property management, and 4) real estate management and consulting services. All of the Company’s revenue streams are U.S. based and substantially all are accounted for as short-term contracts. As such, the performance obligations required to complete contracts have an expected duration of less than one year. As a result, the Company does not disclose the value of unsatisfied performance obligations for contracts in accordance with the optional exemptions related to the disclosure of transaction price allocation under ASC 606. Additionally, incremental costs of obtaining a contract are recognized as an expense when incurred because the amortization period of the asset would have been recognized in one year or less.

Revenue and related profits or losses from homebuilding contracts: the sale of residential properties and units, finished lots and land sales is recognized on the settlement date at the contract sales price, when control is transferred to our customers. These contracts meet the criteria for recognizing revenue at a point in time. As such, these revenues are disaggregated in ‘Individual customers’ and ‘Fixed-price’ in the tables above.

Under the recently executed AMA and most of the Company’s real estate services contracts, performance obligations are satisfied over time. For performance obligations satisfied over time, the objective is to measure progress in a manner which depicts the performance of transferring control to the customer. As such, the company recognizes revenue over time using the “right-to-invoice” cost-to-cost revenue recognition model, which includes cost-plus and fixed-prices contracts, as this depicts when control of the promised goods and/or services are transferred to the customer. Sales are recognized as the ratio of actual costs of work performed to the estimated costs at completion of the performance obligation (cost-to-cost). As such, these revenues are disaggregated in ‘Related party’ and ‘Commercial’ customers, and ‘Cost-plus’ and ‘Fixed-price’ in the tables above.

Other revenue earned from management, consulting and administrative support services provided, which may or may not be covered by a formal contract, are generally time and material based. Revenue from these contracts is recognized as the services are provided. As such, these revenues are disaggregated in ‘Commercial’ and ‘Time and Material’ in the tables above.
