    A participant with at least 5 but less than 8 years of service after September 1, 1941, is entitled to a retirement annuity on or after attainment of age 62.
    A participant who has at least 25 years of service in this system as a police officer or firefighter is entitled to a retirement annuity on or after the attainment of age 50, if Rule 4 of Section 15-136 is applicable to the participant.
    (a-5) A Tier 2 member is entitled to a retirement annuity upon written application if he or she has attained age 67 and has at least 10 years of service credit and is otherwise eligible under the requirements of this Article. A Tier 2 member who has attained age 62 and has at least 10 years of service credit and is otherwise eligible under the requirements of this Article may elect to receive the lower retirement annuity provided in subsection (b-5) of Section 15-136 of this Article.
    (a-10) A Tier 2 member who has at least 20 years of service in this system as a police officer or firefighter is entitled to a retirement annuity upon written application on or after the attainment of age 60 if Rule 4 of Section 15-136 is applicable to the participant.

For a participant, the date on which the annuity payment period begins shall not be prior to termination of employment or more than one year before the application is received by the board; however, if the participant is not an employee of an employer participating in this System or in a participating system as defined in Article 20 of this Code on April 1 of the calendar year next following the calendar year in which the participant attains the age specified under Section 401(a)(9) of the Internal Revenue Code of 1986, as amended, the annuity payment period shall begin on that date regardless of whether an application has been filed. For a recipient of a disability retirement annuity, the date on which the annuity payment period begins shall not be prior to the discontinuation of the disability retirement annuity under Section 15-153.2.
    (c) An annuity is not payable if the amount provided under Section 15-136 is less than $10 per month.
