In its decision on the effective date of IFRS 17, the IASB followed the staff's line of argument that the Board plans to consider whether to explore amend­ments to IFRS 17 and that any un­cer­tainty about those amend­ments could disrupt the progress of im­ple­ment­ing IFRS 17. Together with the sig­nif­i­cant change that IFRS 17 will cause, this con­sti­tutes ex­cep­tional cir­cum­stances that justify the deferral. 14 Board members voted for deferring the effective date of IFRS 17.

The deferral of the fixed expiry date for the temporary exemption to IFRS 9 was a more con­tentious issue as the deferral would mean that some entities would not apply IFRS 9 up to four years after all other entities. However, the IASB concluded that without the deferral there would be two sets of major accounting changes in a short period of time resulting in sig­nif­i­cant cost and effort for preparers of financial state­ments. Avoidance of this had been the Board's original reason for providing the temporary exemption. 13 Board members voted for deferring the expiry date of the exemption.
