In the discretion of the commissioner, any nonprofit organization that elects to become liable for payments in lieu of contributions shall be required within thirty days after the effective date of its election, to execute and file with the commissioner a surety bond approved by the commissioner or it may elect instead to deposit with the commissioner money or securities. The amount of such bond or deposit shall be determined in accordance with the provisions of this section.

(1) The amount of the bond or deposit required by this subsection shall be an amount deemed by the commissioner to be sufficient to cover any reimbursement payments which may be required from the employer attributable to employment during any year for which the election is in effect but in no event shall such amount be in excess of the amount which said employer would pay for such year if he or she were subject to the contribution provisions of this title. The determination made pursuant to this subsection shall be based on payroll information, employment experience, and such other factors as the commissioner deems pertinent.

(2) Any bond deposited under this section shall be in force for a period of not less than two taxable years and shall be renewed with the approval of the commissioner, at such times as the commissioner may prescribe, but not less frequently than at two-year intervals as long as the organization continues to be liable for payments in lieu of contributions. The commissioner shall require adjustments to be made in a previously filed bond as he or she deems appropriate. If the bond is to be increased, the adjusted bond shall be filed by the organization within thirty days of the date notice of the required adjustment was mailed or otherwise delivered to it. Failure by any organization covered by such bond to pay the full amount of payments in lieu of contributions when due, together with any applicable interest and penalties provided for in this title, shall render the surety liable on said bond to the extent of the bond, as though the surety was such organization.

(3) Any deposit of money or securities in accordance with this section shall be retained by the commissioner in an escrow account until liability under the election is terminated, at which time it shall be returned to the organization, less any deductions as hereinafter provided. The commissioner may deduct from the money deposited under this section by a nonprofit organization or sell the securities it has so deposited to the extent necessary to satisfy any due and unpaid payments in lieu of contributions and any applicable interest and penalties provided for in this act. The commissioner shall require the organization within thirty days following any deduction from a money deposit or sale of deposited securities under the provisions of this subsection to deposit sufficient additional money or securities to make whole the organization's deposit at the prior level. Any cash remaining from the sale of such securities shall be a part of the organization's escrow account. The commissioner may, at any time review the adequacy of the deposit made by any organization. If, as a result of such review, he or she determines that an adjustment is necessary he or she shall require the organization to make an additional deposit within thirty days of written notice of his or her determination or shall return to it such portion of the deposit as he or she no longer considers necessary, whichever action is appropriate. Disposition of income from securities held in escrow shall be governed by the applicable provisions of the state law.

(4) If any nonprofit organization fails to file a bond or make a deposit, or to file a bond in an increased amount or to increase or make whole the amount of a previously made deposit, as provided under this section, the commissioner may terminate such organization's election to make payments in lieu of contributions and such termination shall continue for not less than the four-consecutive-calendar-quarter period beginning with the quarter in which termination becomes effective: PROVIDED, That the commissioner may extend for good cause the applicable filing, deposit, or adjustment period by not more than thirty days.
