Sales of goods is recognized at the time of shipment only if it meets the conditions that significant risks and rewards of ownership of the goods have been transferred to the customer, and neither continuing managerial involvement nor effective control over the goods sold is retained. Revenue arising from rendering of services is generally recognized by the percentage-of-completion method at the date of the end of the reporting period. In addition, revenue arising from interest, dividends or royalties is recognized when it is probable that future economic benefits will flow into the Company and those benefits can be measured reliably.
