it is mentioned that provision for product warranty claims were estimated at a percentage of sales on past experience. Tax auditors had clearly specified that such provision was not a contingent liability and assessee had relied on decisions of this Tribunal as well as those of Hon'ble Jurisdictional High Court in this regard.
