W. Va. Code § 13-2-4

The governing body of the political body of the political subdivision issuing bonds under this article may sell the same or any part thereof and collect the proceeds, or such bonds may be delivered to the holder or holders of the bonds to be refunded in exchange therefor.

It is the intention of this article to authorize political divisions to issue bonds for the purpose of refunding outstanding bonds without thereby contracting any additional indebtedness, and it shall be conditional upon the delivery of any refunding bonds that the bonds to be refunded be canceled and paid simultaneously with the issuance and delivery of such refunding bonds: Provided, That such refunding bonds shall be issued in an amount sufficient to effect the refunding and may include an amount sufficient to pay (1) the principal amount outstanding of the bonds to be refunded, (2) interest accrued or to accrue to the date of maturity or the date of redemption of the bonds to be refunded (which need not necessarily be on the first available redemption date), (3) any redemption premiums to be paid thereon, (4) any reasonable expenses incurred in connection with such refunding and (5) any other reasonable costs deemed appropriate by the state, including without limitation, the expenses of preparing and delivering the refunding bonds, legal fees, financial advisor fees, consultant fees, and other expenses incurred in connection with the issuance, sale and delivery of the refunding bonds.

For all purposes of this section, bonds shall be considered to have been canceled and paid in advance of their due date or date of redemption if there shall have been deposited with the West Virginia Municipal Bond Commission either:

(a) Moneys, sufficient to pay when and as due at maturity or prior redemption all amounts of principal, redemption premium, if any, and interest payable on such bonds; or

(b) Direct obligations of the United State of America or the State of West Virginia, or obligations fully and irrevocably secured as to the payment of both principal and interest by such direct obligations, the payment on which when due will provide moneys, sufficient to pay when and as due at maturity or prior redemption all amounts of principal, redemption premium, if any, and interest payable on such bonds.

All such amounts shall be set aside and held in trust and irrevocably dedicated solely to the payment of such bonds, except that amount in excess of the amounts required for the payment of the bonds so refunded may be applied to the payment of costs related to the issuance, carrying, insuring or servicing the refunding bonds, including costs of credit or market enhancement services, such as letters of credit, remarketing arrangements and similar services. Any amount deposited pursuant to this section may include amounts already held on deposit by the West Virginia Municipal Bond Commission for the payment of the bonds to be refunded.
