Substantial Doubt about Going Concern [Text Block]	2. Going Concern A fundamental principle of the preparation of financial statements in accordance with GAAP is the assumption that an entity will continue in existence as a going concern, which contemplates continuity of operations and the realization of assets and settlement of liabilities occurring in the ordinary course of business. This principle is applicable to all entities except for entities in liquidation or entities for which liquidation appears imminent. In accordance with this requirement, the Company has prepared its accompanying Consolidated Financial Statements assuming the Company will continue as a going concern. We do not have adequate liquidity, including access to the debt and equity capital markets, to operate our business over the next 12 months from the date of issuance of this Form 10-K. The Company incurred a net loss of $611,000 in 2016 and had a working capital deficiency of $4.0 million as of December 31, 2016. As such, there is substantial doubt about the Company’s ability to continue as a going concern for the next 12 months from the date of issuance of this Form 10-K. As a result, our short-term business focus has been to preserve our liquidity position. Unless we are successful in obtaining additional liquidity, we believe that we will not have sufficient cash and liquid assets to fund normal operations for the next 12 months from the date of issuance of this Form 10-K. In addition, the Company’s obligations under its pension plan exceeded plan assets by $4.4 million at December 31, 2016 and the Company has a significant amount due to its pension plan over the next 12 months. The Company is in default on its 8¼% Limited convertible senior subordinated notes due 2012 (the "Notes") and 9½% Subordinated debentures due 2012 (the "Debentures"), which have remaining principal balances of $387,000 and $220,000, respectively. As a result, if the Company is unable to (i) obtain additional liquidity for working capital, (ii) make the required minimum funding contributions to the defined benefit pension plan and/or (iii) make the required principal and interest payments on the Notes and the Debentures, there would be a significant adverse impact on the financial position and operating results of the Company. The accompanying financial statements do not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amounts and classification of liabilities that may result from the outcome of this uncertainty. See Note 11 - Long-Term Debt for further details. The Company is seeking additional financing in order to provide enough cash to cover our remaining current fixed cash obligations as well as providing working capital. However, there can be no assurance as to the amounts, if any, the Company will receive in any additional financings or the terms thereof. To the extent the Company issues additional equity securities, it could be dilutive to existing shareholders.

2. Going Concern

A fundamental principle of the preparation of financial statements in accordance with GAAP is the assumption that an entity will continue in existence as a going concern, which contemplates continuity of operations and the realization of assets and settlement of liabilities occurring in the ordinary course of business. This principle is applicable to all entities except for entities in liquidation or entities for which liquidation appears imminent. In accordance with this requirement, the Company has prepared its accompanying Consolidated Financial Statements assuming the Company will continue as a going concern.

We do not have adequate liquidity, including access to the debt and equity capital markets, to operate our business over the next 12 months from the date of issuance of this Form 10-K. The Company incurred a net loss of $611,000 in 2016 and had a working capital deficiency of $4.0 million as of December 31, 2016.
