708.When can the simplified old-start formula be used?

Use of the simplified old-start formula requires that you meet the following conditions:

1. You have at least one quarter of coverage before 1951;

2. You have reached age 62, died, or become disabled after December 1977;

3. You have reached age 22 after 1937 and before 1951; or you have reached age 22 after 1950 and have less than six quarters of coverage after 1950; and

4. You did not have a period of disability that began before 1951, unless the period of disability is entirely ignored (because a higher PIA results by including the period of disability).
