Example. Corporation A is a majority shareholder of Corporation B, which is a majority shareholder of Corporation C. A change in ownership of Corporation B constitutes a change in control event to service providers performing services for Corporation B or Corporation C, and to service providers for which Corporation B or Corporation C is solely liable for payments under the plan (for example, former employees), but is not a change in control event as to Corporation A or any other corporation of which Corporation A is a majority shareholder unless the sale constitutes a change in the ownership of a substantial portion of Corporation A's assets (see paragraph (i)(5)(vii) of this section).
Example. Company B (intermediate service recipient) provides services to Company C (ultimate service recipient). Employee A (service provider) provides services to Company B that are closely related to the services Company B provides to Company C. Pursuant to a nonqualified deferred compensation plan meeting the requirements of section 409A, Employee A is entitled to a payment of deferred compensation upon a separation from service with Company B (the intermediate service recipient plan). Under an arrangement between Company B and Company C (the ultimate service recipient plan), Company C agrees to pay an amount of deferred compensation to Company B upon Employee A's separation from service with Company B, in accordance with the time, form and amount of payment provided in the intermediate service recipient plan. Provided that the intermediate service recipient plan and the ultimate service recipient plan otherwise comply with the requirements of section 409A (regardless of whether such arrangements are subject to section 409A), Company C's payment to Company B of the amount due under the ultimate service recipient plan upon the separation from service of Employee A from Company B may constitute a permissible payment event for purposes of paragraph (a) of this section.
