to non off-take or under-drawal by the customers as per the respective GSAs, and was not to make any profits on account of take or pay deficiency. The same also formed basis of reduction in the take or pay claim by the Opposite Party. However, in the instant matter, full ToP liability has been imposed on the Informant for the calendar year 2015. In the earlier cases, the Opposite Party also contended that it faces ToP obligation under its contracts with certain upstream suppliers. In this regard, the Commission finds it relevant to inquire into: the different sources of gas procurement by the Opposite Party and the nature of arrangements with each supplier including price and ToP liability under each such arrangement; whether the gas supplied to the customers of the Opposite Party is supplied from a commingled stream, in which case, what is the basis for price determination/ revision from time to time; whether ToP liability was imposed on the Opposite Party by its upstream suppliers for the contract year 2015; whether the Opposite Party has suffered any loss on account of non off-take or under-drawl of gas by its contracted customers during the contract year 2015; what were the total ToP liabilities levied by the Opposite Party on all its customers located across India for the contract year 2015; whether the Opposite Party had adopted any discriminatory practice in imposition of ToP liability upon its customers located across India; whether the Opposite Party imposed full ToP liability only in cases where the concerned buyer contested the legality of the ToP claim or resorted to litigation/ arbitration proceedings; and the policy, if any, of the Opposite Party regarding imposition of different liability upon different class of customers. It would also be relevant to appreciate the rationale behind the Opposite Party committing ToP liability to its upstream suppliers for a long period i.e. whether the Opposite Party took into consideration the potential inclusions and exclusions in its customer base, fluctuations in prices, different modes of risk management etc .
