Replacement of a disability pension with an old-age pension

The disability pensions of persons who have reached the statutory retirement age have been replaced with old-age pensions.
A person born before 1 January 1949 is granted an old-age pension ex officio irrespective of whether s/he meets the condition of the (contributory and non-contributory) insurance period of at least 20 years for women and 25 years for men, which is required when a retirement pension is awarded.
The old-age pension, awarded ex officio is calculated based on the pension assessment basis. The amount of such a pension may not be lower than the amount of the previously acquired disability pension.
A person born after 31 December 1948 is awarded an old-age pension ex officio after having attained the retirement age. A woman who has been awarded an old-age pension ex officio, and who will reach the statutory retirement age in 2009–2014, may request a pension calculation of a mixed amount (partly under the old and partly under the new rules).
The amount of the old-age pension granted ex officio to a person who has met the conditions of the insurance period is increased to the minimum pension amount.
If the disability pension was paid in an amount as awarded to a person who is partly incapable of work, and yet to someone who had not completed the required qualifying period, which means that s/he would not meet the requirements for an old-age pension, the old-age pension awarded ex officio will not be brought up to the level of the minimum old-age pension.
An old-age pension is not awarded ex officio to a person whose right to an old-age pension and a disability pension had been already established, but who opted for a disability pension instead.
