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 based on Generally Accepted Accounting Principles (GAAP), or at the discretion of the Commissioner, modified GAAP, or Statutory Accounting Principles, as follows:
The 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.
The Commissioner 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 any applicable valuation or method used by insurers in general, or any such method then currently formulated, or approved or permitted by the National Association of Insurance Commissioners or its successor organization.
