Price indexation clause

Definizione

A price indexation clause links periodic price adjustments to a named published index, most often the Consumer Price Index, so that the price tracks inflation without renegotiation. The clause should specify the exact index series, the reference period, the adjustment frequency and the formula. Ambiguity over which index figure applies is a frequent source of contract disputes, especially in leases and long-term supply.

Esempio

The lease indexation clause adjusts rent each year by the percentage change in the CBS CPI for all households.

Perché rappresenta un rischio aziendale

A price indexation clause that does not specify the exact index series, reference month or formula creates a recurring annual dispute. In years of high inflation, the financial stakes are significant: a 1% difference in the index applied to a multi-million-euro lease portfolio is material. Missed adjustment dates also create a risk of under-recovery that cannot always be claimed retrospectively.

Come gestirlo

• Name the index series, publisher, reference month and year of first adjustment explicitly in the clause.
• Set out the formula: new price = current price x (new index / base index). Avoid ambiguous formulations like "in line with inflation".
• Include a cap and floor if appropriate, and specify whether an unclaimed adjustment accumulates or lapses for the missed period.
• Diarise adjustment dates with advance reminders so the new price is calculated, communicated and invoiced on time.
• Review the clause at each renewal to ensure the named index is still published in the same form and update the reference if the index has been revised or discontinued.
