TNMM aggregation prevented separate benchmarking of IT support services where accepted segmental margins already included the associated-enterprise markup and the services were inextricably linked to the core business. The transfer-pricing adjustment on the IT support-services margin was deleted. Notional interest on overdue associated-enterprise receivables was unwarranted because the taxpayer was debt-free, incurred no significant interest cost, and no new material justified departure from earlier treatment; the related adjustment was deleted. Capital expenditure on an in-house scientific-research facility remained deductible under section 35(1)(iv) despite the concessional tax regime and absence of valid Form 3CM, which was relevant to section 35(2AB), not section 35(1)(iv).
