Broadly speaking: •  the deposit rule requires that a minimum of 60 per cent of the excess between actual and budgeted energy revenues must be credited to the Fund, while;  •  the withdrawal rule allows the Government to tap into the Fund to cover 60 per cent of any revenue shortfalls.
There is a cap on the amount of the Fund that could be used for stabilization. There are some other significant provisions in the law or in the principles underlying the Fund.
