Those members whose membership expires upon their separation from their duties due to any reason after at least a 10-year subscription to the Foundation shall benefit from the retirement benefit.

Retirement benefit consists of an amount calculated over the saving premiums paid to the Foundation during the periods of active service.

Members, who entitled to receive retirement benefit, may enter into "Retirement Pension System" by leaving 1/4 or 2/4 or 3/4 or entire amount of retirement benefit in the Foundation. Profit sharing of the members are paid out with quarterly payments.

Members who enter into "Retirement Pension System" continue to take advantage of benefiting from OYAK's social services, loans and house procurement benefits based on their rate of participation.

Members within the "Retirement Pension System" have the right to leave the System by taking their reserves following 3 years as of entry into the System. However, whoever quit the System cannot be admitted to the System again.

In case of the death of Retirement Pension System's member, a death benefit equivalent to 10 times the amount of recent monthly pension is to be paid to his/her legal heirs.

The surviving spouse of a deceased member can choose to continue receiving the annuity.

Another system, that aims to provide retirement income is "Donation Based Retirement Income System". This system provides additional life-long income to members who receive retirement benefits, members on active duty of 10 years standing and those who have worked for more than 10 years in equity participations in which OYAK has the majority share. The participant makes to the Foundation a donation and begins to get quarterly income after 1 year. The reserve left in the system is paid to the participant's heirs after his death by an insurance company.
