Wyo. Stat. § 21-17-420: Repurchase of securities by board.

Any bonds or other securities may be repurchased by the board out of any funds available for that purpose at a price of not more than the principal amount thereof and accrued interest, plus the amount of the premium, if any, which might on the next prior redemption date of the securities be paid to the holders thereof if the securities should be called for redemption on such date pursuant to their terms. All securities repurchased shall be cancelled. If the securities may not be called for prior redemption at the board's option within one (1) year from the date of their purchase, they may be repurchased without limitation as to price.
