A (former) participant is entitled to an old-age pension from the day he reaches the pensionable age according to the General Old Age Pension Act [in Dutch: AOW]. The General Old Age Pension is a basic state pension granted by the Social Insurancebank [in Dutch: ‘Sociale Verzekeringsbank’; abbreviated as SVB] for people who have reached their General Old Age Pension-age.
Under conditions the employee and the (former) participant can request for an old age pension before the General Old Age Pension-age, but not before the first day of the month in which the age of 60 is reached.
