If, by reason of an increase in the cost of living or changes in the level of wages or salaries or other reasons for adjustment, the benefits of the States concerned are altered by a fixed percentage or amount, such percentage or amount must be applied directly to the benefits determined under Article 46, without the need for a recalculation in accordance with that Article.

On the other hand, if the method of determining benefits or the rules for calculating benefits should be altered, a recalculation shall be carried out inaccordan ce with Article 46.
