These Model Clauses are intended for use with the 2005 ISDA Commodity Definitions (the “Commodity Definitions”). They are designed to enable parties to incorporate express contractual provisions into confirmations and/or ISDA Master Agreements to clarify the consequences of a Floating Amount determined under Section 6.1 (Calculation of a Floating Amount) of the Commodity Definitions being a negative amount. Please note that the publication of these Model Clauses does not imply, and should not be construed as implying, that a negative Floating Amount would or would not be payable under the terms of the Commodity Definitions (absent use of one of the Model Clauses).
