Meaning
Post-transaction adjustment methods reconcile the difference between an estimated price and the actual market value at the time of delivery. Variance adjusted settlement ensures that both the buyer and the seller are protected from sudden price swings during the fulfillment period. This mechanism is common in energy, commodities, chemical processing, and large-scale manufacturing where the cost of raw materials fluctuates daily.
The final payment is calculated by applying a pre-agreed formula to the delta between the contract strike price and the spot price. Such adjustments preserve the economic intent of the agreement regardless of temporal volatility.
Risk Mitigation
Hedging against volatility is the primary goal of this settlement style. Variance adjusted settlement allows firms to commit to long-term supply contracts without the fear of a market crash destroying their margins. By sharing the price risk, both parties can plan their budgets with greater confidence.
The agreement defines the threshold of variance that triggers a payment adjustment.
Price Correction
Accuracy in the final invoice depends on the quality of the external data used for the adjustment. When using variance adjusted settlement, the contract must specify the index or benchmark that acts as the source of truth for the market price. This prevents disputes over the calculation of the final amount due.
The adjustment can be a simple linear function or a more complex calculation involving floor and ceiling prices.
Settlement Finality
Closing the books on a transaction requires the successful application of these adjustments. Variance adjusted settlement concludes the commercial obligation by bringing the transaction price in line with the economic reality of the delivery window. Once the variance is calculated and paid, the contract is considered fully executed.
