Though there is no definition of the term ‘total turnover’ in section 10A, there is also nothing in the said section to mandate that what is excluded from the numerator (export turnover) would nevertheless form part of the denominator. One would have to apply consistent standards in understanding and applying a term, particularly when, such term, viz. export turnover has an independent function and at the same time a part of a larger term viz., total turnover.Thus, if some expenses, for any reason are excluded in arriving at the ‘export turnover’ the same should be reduced form ‘total turnover’ also.
