Vt. Stat. tit. 8 § 3563

Such an inspection and examination shall be conducted personally or by a competent person appointed by the Commissioner at least every three years and whenever determined to be prudent by the Commissioner. The Commissioner may enlarge the aforesaid three-year period to five years, provided the insurer is subject to a comprehensive annual audit during such period of a scope satisfactory to the Commissioner by independent auditors approved by the Commissioner. The examination shall include a review of the financial analysis performed by the Commissioner and shall be conducted in accordance with statutory accounting principles pursuant to guidelines, principles, manuals, instructions, and other procedures promulgated by the National Association of Insurance Commissioners, together with any useful or necessary modifications or adaptations thereof required or approved by the Commissioner.
