053-14 Wyo. Code R. § 14-2
If an employer who has elected the reimbursing option of W.S. 27-3-509 is not affiliated with an organization that will assume financial liability for benefit claims or fails to pay contributions when due, or otherwise fails to comply with the requirements of the Wyoming Employment Security Law or the commission's rules, the division may require that employer to file a bond on a form to be approved by the division. Said bond shall be in an amount equal to the current maximum benefit amount multiplied by the number of employees (annual average for established accounts) or $15,000, whichever is higher. This bond will be retained for two years after the entity stops doing business and used to repay benefit charges as applicable. The condition of the bond shall be in compliance with the Wyoming Employment Security Law and rules issued under it, including reimbursing the division for benefits charged to the employer and filing reports by the due date.
