Wyo. Stat. § 9-4-814

The state treasurer may sell any or all collateral that may be pledged as security for the deposit of any state funds in any depository under this act, at public or private sale, whenever there shall be a failure or refusal upon the part of any state depository, to pay over the funds, or any part thereof or interest thereon, upon the demand or order of the state treasurer, or his authorized deputy on the state depository. Notice of the sale of collateral given as security for deposits is required only if the state treasurer finds that the collateral is illiquid. If notice is required, it shall be given by publication once each week for three (3) consecutive weeks in a newspaper of general circulation in the county or counties in which real estate, in the case of mortgages, or the local governments, in the case of local government bonds, are located. When a sale of collateral is made by the state treasurer, either at public or private sale, and the collateral has been transferred by the chairman and secretary of the board of deposits, the absolute ownership of the collateral shall vest in the purchasers, upon the payment of the purchase money to the state treasurer. Should there be any surplus after paying the amount due the state and expenses of sale, it shall be paid to the state depository which made the pledge of the collateral.
