Under section 4.02 of EPCRS, you can self-correct insignificant errors while under examination. See below. Not sure reallocating an entire year would qualify as "insignificant." If these won't work, I think you'll have to use Audit CAP.
.02 Effect of examination. If the plan or Plan Sponsor is Under Examination, VCP is not available. SCP is available only as follows:
(1) Insignificant Operational Failures. While the plan or Plan Sponsor is Under Examination, insignificant Operational Failures may be corrected under SCP.
(2) Significant Operational Failures. If correction of significant Operational Failures has been substantially completed (as described in section 9.03) before the plan or Plan Sponsor is Under Examination, the Plan Sponsor may complete correction of those failures under SCP.
