The change means that people retiring at the same age will receive lower calculated pensions from 2027. The two supplied reports agree on the central effect: the revised coefficients reduce the pension payment produced by the calculation for a given retirement age.
ANSA Economia identifies the age-67 coefficient as 5.514 under the new system. The supplied report does not provide the previous coefficient, so the available evidence does not establish the size of the change in percentage terms at that age.
La Repubblica attributes the reduction in the coefficients to increased life expectancy. It reports that pension payments could be reduced by up to 2%, while stressing the financial effect through an example involving €300,000 in contributions: an annual gross pension reduction of €284.
La Repubblica also reports that the change raises the age of exit, but the supplied material does not quantify that effect or explain its mechanism. The available evidence does not establish one precise reduction for every individual pension.
