The bond, or security deposit, shall be for the benefit of the commonwealth solely to pay claims and associated expenses and payable on the failure of the group to pay workers' compensation benefits which it is legally obligated to pay. The commissioner may establish requirements for the amount of security based on differences among groups in their size, types of employment, years in existence, and other relevant factors; provided, however, that the commissioner of insurance may not require an amount lower than one hundred thousand dollars for any group during its first year of operation;
The commissioner may periodically review a group's security deposit or bond and excess and aggregate insurance to determine if the minimum requirements established by the commissioner are being met.
