Weather Index Swap transactions are OTC derivative transactions which settle financially based on an index calculated from observations of temperature and precipitation at weather stations throughout the world. Sub-Annex C of the 2005 ISDA Commodity Definitions provides definitions and terms for a number of types of weather indices. These indices include: HDD (heating degree days), CDD (cooling degree days), CPD (critical precipitation days). Weather Index Swap transactions result in a cash flow to one of the two counterparties each Calculation Period depending on the relationship between the Settlement Level and the Weather Index Level.</xsd:documentation>
