(iii) if, on the cessation of his employment, the employee obtains employment with any other employer, to the extent the accumulated balance due and becoming payable to him is transferred to his individual account in any recognised provident fund maintained by such other employer; or
(iv) if the entire balance standing to the credit of the employee is transferred to his account under a pension scheme referred to in section 80CCD and notified by the Central Government.
