Vt. Stat. Ann. tit. 24, § 5065

Should any change or error in the records result in any member or beneficiary receiving from the Retirement System more or less than he or she would have been entitled to receive had the records been correct, the Retirement Board shall have the power to correct such error, and to adjust as far as practicable the payments in such a manner that the actuarial equivalent of the benefit to which such member or beneficiary was correctly entitled shall be paid or in such a manner that the impact upon the Fund is de minimis.
