[1] Revenue from the provision of construction services is recognized over time, using an input method to measure progress towards complete satisfaction of the service, because the Group’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced. The input method recognizes revenue based on the proportion of the actual costs incurred relative to the estimated total costs for the satisfaction of the construction services. A certain percentage of payments is retained by customers until the end of the retention period, as the Group’s entitlement to the final payment is conditional on the satisfaction of the service quality by the customers over a certain period, as stipulated in the contracts.
[2] Gross profit for the public sector and private sector was negative US$4.82 million and negative US$2.29 million, respectively, for the year ended March 31, 2026 compared to US$5.06 million and negative US$1.14 million respectively, negative gross profit was primarily due to cost overruns and final account adjustments on certain legacy projects. These contracts have been substantially completed, and no provision for future contract losses is required as of March 31, 2026.
