625.141  Valuation of bonds.--

(1)  All bonds or other evidences of debt having a fixed term and rate of interest held by an insurer may, if amply secured and not in default as to principal or interest, be valued as follows:

(a)  If purchased at par, at the par value.

(b)  If purchased above or below par, on the basis of the purchase price adjusted so as to bring the value to par at maturity and so as to yield in the meantime the effective rate of interest at which the purchase was made, or in lieu of such method, according to such accepted method of valuation as is approved by the department.

(c)  Purchase price shall in no case be taken at a higher figure than the actual market value at the time of purchase, plus actual brokerage, transfer, postage, or express charges paid in the acquisition of such securities.

(2)  The department shall have full discretion in determining the method of calculating values according to the rules set forth in this section, but no such method or valuation shall be inconsistent with the method formulated or approved by the National Association of Insurance Commissioners or its successor organization and set forth in the latest edition of its publication "Valuation of Securities"; provided that such valuation methodology is substantially similar to the methodology used by the National Association of Insurance Commissioners in its 1988 edition of such publication.
