Note on Revenue Recognition

The company has clarified that the total value of orders executed during the period represents the aggregate amount of invoices raised on customers. Revenue recognized under Indian GAAP (Ind AS 115 – Revenue from Contracts with Customers) may differ from the invoiced amount due to the application of various Incoterms and performance obligations under respective contracts. Revenue recognition is aligned with the transfer of control of goods or services to the customer, and not merely based on invoicing milestones. Accordingly, revenue recognized during the reporting period may be lower than the total invoiced value for the same period.
