Viewing index curve values

An Index curve value represents market-based pricing information, either externally published or internally maintained, used to determine commodity prices for a specific location, pipeline, product, or time period. These values provide the foundational inputs for price calculations across billing, settlements, forecasting, and risk management processes.

Index curve values are applied whenever transactions, contracts, or settlements depend on variable pricing linked to market indices. They are referenced across multiple system modules, including pricing, billing, and settlements, to calculate payments, accruals, mark-to-market valuations, and exposure.

Configuration of index and curve definitions is managed within the Index/Curve definition screen. Once defined, index values are periodically updated, either manually entered or automatically refreshed through imported market data feeds, to ensure alignment with current market conditions.
