The Budget Stabilization Fund was created in 1990 for use as a source of funding in times of declining revenues. The fund receives its monies from excess mineral revenues, non-recurring revenues, monies in excess of the expenditure limit, investment earnings, and other monies appropriated by the legislature. One-third of the fund balance can be spent if the official forecast for recurring revenues for the upcoming fiscal year is less than the official forecast of recurring revenues for the current fiscal year, or if a deficit for the current fiscal year is projected due to a decrease in recurring revenues.
