(a) If you are a woman, or a man born after January 1, 1913, the period of elapsed years in Sec. 404.110(b) used in determining the number of quarters of coverage (QCs) you need to be fully insured ends as of the earlier of--
(1) The year you become age 62; or
(2) The year in which--
(i) Your period of disability begins;
(ii) Your waiting period begins (see Sec. 404.315(d)); or
(iii) You become entitled to disability insurance benefits (if you do not have to serve a waiting period).
(b) If you are a man born before January 2, 1913, the period of elapsed years in Sec. 404.110(b) used in determining the number of QCs you need to be fully insured ends as of the earlier of--
(1) The year 1975; or
(2) The year specified in paragraph (a)(2) of this section. [45 FR 25384, Apr. 15, 1980, as amended at 49 FR 28547, July 13, 1984]
