Liquidation Basis of Accounting [Text Block]	2. As a result of the Board’s approval of the Plan of Liquidation and Dissolution, the Company adopted the Liquidation Basis of Accounting, effective April 18, 2018.  Under the Liquidation Basis of Accounting, all of the Company’s assets have been stated at their estimated net realizable value and are based on current contracts, estimates and other indications of sales value net of estimated selling costs. All liabilities of the Company have been stated at contractual amounts and those estimated costs associated with implementing the Plan of Liquidation and Dissolution have been stated at their estimated settlement amounts.  The valuation of assets at their net realizable value and liabilities at their anticipated settlement amount represent estimates, based on present facts and circumstances, of the net realizable value of the assets and the costs associated with carrying out the Plan of Liquidation and Dissolution. The actual values and costs associated with carrying out the Plan of Dissolution are expected to differ from amounts reflected in the accompanying financial statements because of the Plan’s inherent uncertainty.

Liability for Estimated Costs During Liquidation [Text Block]	3. The Liquidation Basis of Accounting requires the Company to estimate net cash flows from operations and to accrue all costs associated with implementing and completing the Plan of Liquidation and Dissolution. These amounts can vary significantly due to, among other things, the costs of retaining personnel and others to oversee the liquidation, the cost of insurance, the timing and amounts associated with discharging known and contingent liabilities and the costs associated with cessation of the Company’s operations, including an estimate of costs subsequent to that date. As a result, the Company has accrued the projected costs, including corporate overhead and specific liquidation costs of severance, professional fees, and other miscellaneous wind-down costs expected to be incurred during the projected period and required to complete the liquidation of the Company’s remaining assets.  These accruals will be adjusted from time to time as projections and assumptions change. These costs are anticipated to be paid throughout the liquidation period.
