SANDRIDGE MISSISSIPPIAN TRUST I (NYSE: SDT) today announced a quarterly distribution for the period from June 1, 2011 through August 31, 2011 of $22.9 million, or $0.816423 per unit. Quarterly cash available for distribution on all units exceeded 120% of the target distribution (the “Incentive Threshold”), resulting in a distribution equal to the Incentive Threshold plus 50% of the amount by which cash available for distribution exceeded the Incentive Threshold. The distribution is expected to occur on or before November 30, 2011 to holders of record as of the close of business on November 15, 2011. The Trust was formed by SandRidge Energy, Inc. ("SandRidge") in December 2010 to own royalty interests in oil and natural gas properties owned by SandRidge in the Mississippian formation in Alfalfa, Garfield, Grant, Major and Woods counties in Oklahoma and is entitled to receive proceeds from the sale of production attributable to the royalty interests. As described in the Trust's filings with the Securities and Exchange Commission (the “SEC”), the amount of the quarterly distributions is expected to fluctuate from quarter to quarter, depending on the proceeds received by the Trust as a result of actual production volumes, oil and natural gas prices and the amount and timing of the Trust's administrative expenses, among other factors. Although there is no assurance of any minimum distribution in any quarterly period, during the subordination period (as described in the Trust's filings), holders of Common Units will be entitled to receive an amount up to the "Subordination Threshold" (which varies from quarter to quarter) prior to any distribution being made for that quarter in respect of the Subordinated Units, all of which are held by SandRidge. If the amount available for distribution in any quarterly period is sufficient to distribute an amount equal to the Subordination Threshold to the holders of all units (including the Subordinated Units), any additional balance is distributed to holders of all units, up to the amount of the Incentive Threshold for the quarter. Trust units are entitled to receive 50% of any cash available for distribution in excess of the Incentive Threshold for the quarter, which for the period from June 1, 2011 through August 31, 2011 was approximately $0.4 million or $0.015762 per unit.
