 deductible expenditure and the incurrence of the Sales Commission
 expenditure.
 
 (ii) In the aforesaid assessment order, Sales commission expenditure
 amounting Rs.2,93,25,806/- was disallowed by the department as not

 paid towards quantity and other discounts provided to customers. The
 Company strongly believes that the disallowance has been incorrectly
 made by the Department based on certain assumptions on the method of
 working of the Commission agents and the question of genuineness of the
 aforesaid sales commission expenditure incurred by the Company is
 beyond doubt and such tax claims are not tenable. Also refer para (iii)
 below.
