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. The Company incurred a net loss of $1.7 million in 2015 and has a working capital deficiency of $2.5 million as of December 31, 2015. 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. In addition, the Company’s obligations under its pension plan exceeded plan assets by $5.3 million at December 31, 2015 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 $626,000 and $334,000, respectively.
