The valuation of the balance between the acquired pension entitlements and liabilities of the mandatory pension insurance system is conducted on the basis of the Pension Fund’s (PFR) actuarial model, developed and verified by a specialized department of the PFR - the Department for Actuarial Valuations and Strategic Planning. This model is a unique product and enabler to accumulate every specific option of pension entitlement valuation under the national pension legislation. The actuarial valuations take into account detailed differentiation by pension insurance types, individual incomes, length of service, gender and age.

The actuarial valuations database, which is the source of information for the model, contains diversified internal resources as well as data from external sources, making it possible to assess any assumed changes in pension entitlements and the financing of liabilities in a rapid and highly professional manner, and to conduct a long-term evaluation of the decisions adopted.

Preparing to ratify the ILO C102 on Minimum Standards of Social Security, a method (principles) has been developed in order to calculate a replacement rate for old-age, disability and survivor pensions.
