N.D. Cent. Code § 54-44-16
Upon request of the director of the office of management and budget and upon approval by the industrial commission, the state investment board may purchase oil put options for the office of management and budget. The purchase of put options must be designed to offset reduced state general fund oil and gas tax revenues due to oil and gas prices falling below selected levels. Put options may be purchased only at such times that the purchase assures that oil tax revenues plus the revenues from the sale of put options will be in excess of the oil tax revenues estimated for that level of production by the most recently adjourned legislative assembly. The office of management and budget shall report any purchases of put options to the budget section of the legislative management.
