Unemployment Insurance Code section 1051

Whenever any employing unit acquires the organization, trade, or business, or substantially all of the assets thereof, or a distinct and severable portion of such organization, trade, or business, of any employer, excepting any assets retained by the employer incident to the liquidation of his obligations (whether or not the acquiring employing unit was an “employing unit” within the meaning of Section 135 prior to such acquisition), and continues such organization, trade, or business, or such distinct and severable portion thereof without substantial reduction of personnel resulting from such acquisition, an application may be made within 90 days of such acquisition for transfer of reserve account. The application shall contain the name and address of the predecessor, the date of acquisition, the name of the successor, the number of employees prior to and subsequent to the date of acquisition, and, in case of severable portions, such pay roll data as may be required by the department to determine the proper amount to be transferred.
