B.The provisions of this subsection shall be applicable only to the determination of contribution rates for the calendar year 1956 and for each calendar year thereafter. Whenever any employing unit has succeeded to substantially all of the employing enterprises of another employing unit, but the predecessor employing unit has retained a distinct severable portion of its employing enterprises or whenever any employing unit has succeeded to a distinct severable portion which is less than substantially all of the employing enterprises of another employing unit, the successor employing unit shall acquire the experience rating record attributable to the portion to which it has succeeded, and the predecessor employing unit shall retain the experience rating record attributable to the portion which it has retained, if-- 1.It files a written application for such experience rating record which is joined in by the employing unit which is then entitled to such experience rating record; and 2.The joint application contains such information as the Director shall by regulation prescribe which will show that such experience rating record is identifiable and segregable and, therefore, capable of being transferred; and 3.The joint application is filed prior to whichever of the following dates is the latest: (a) July 1, 1956; (b) one year after the date of the succession; or (c) the date that the rate determination of the employing unit which has applied for such experience rating record has become final for the calendar year immediately following the calendar year in which the succession occurs. The filing of a timely joint application shall not affect any rate determination which has become final, as provided by Section 1509. If all of the foregoing requirements are met, then the Director shall transfer such experience rating record to the employing unit which has applied therefor, and it shall not be treated as the experience rating record of the employing unit which has joined in the application.
Whenever any employing unit is reorganized into two or more employing units, and any of such employing units are owned or controlled by the same interests which owned or controlled the predecessor prior to the reorganization, and the provisions of this subsection become applicable thereto, then such affiliated employing units during the period of their affiliation shall be treated as a single employing unit for the purpose of determining their rates of contributions.
