In relation to the first step of the Ting Choon Meng approach, counsel for the Appellant, Mr Allen Tan Tiaw Kheng, submits that the phrase “for undertaking on his behalf” is satisfied so long as there is a payment made in return for the benefit of another party performing, carrying on, or committing to perform R&D for the taxpayer. As such, it is irrelevant that Intevac US could also have benefitted from the R&D performed by itself and by the Appellant under the CSA. Conversely, counsel for the Respondent, Ms Quek Hui Ling, argues that “for undertaking on his behalf” imports the concept of agency, and refers to situations where the taxpayer outsources the R&D to an organisation which then undertakes R&D wholly and exclusively for the taxpayer’s benefit.
