Going Concern [Text Block]	2. Liquidity/Going Concern The Company incurred substantial losses during the first six months of 2013, having net losses of $2,262,000 and negative operating cash flows of approximately $1,921,000. As of June 30, 2013, the Company had an accumulated deficit of $147,179,000. These facts raise substantial doubt as to the Company’s ability to continue as a going concern. The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue on a going concern basis which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business and do not include any adjustments that might result from uncertainty about the Company’s ability to continue as a going concern. Management’s plan to alleviate the going-concern uncertainty includes, but is not limited to, the issuance of equity and debt instruments for working capital. The Company’s continued existence is also dependent upon its ability to increase revenues generated from operations which will enable the Company to achieve a profitable level of operations. If anticipated operating results are not achieved, management has the intent, and believes it has the ability, to further delay or reduce expenditures. In such case, the further reduction in operating expenses might need to be substantial. Failure to generate sufficient cash flows from operations, raise additional capital, or reduce certain discretionary spending would have a material adverse effect on the Company’s ability to achieve its intended business objectives.

2. Liquidity/Going Concern

The Company incurred substantial losses during the first six months of 2013, having net losses of $2,262,000 and negative operating cash flows of approximately $1,921,000. As of June 30, 2013, the Company had an accumulated deficit of $147,179,000. These facts raise substantial doubt as to the Company’s ability to continue as a going concern.

The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue on a going concern basis which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business and do not include any adjustments that might result from uncertainty about the Company’s ability to continue as a going concern.

Management’s plan to alleviate the going-concern uncertainty includes, but is not limited to, the issuance of equity and debt instruments for working capital. The Company’s continued existence is also dependent upon its ability to increase revenues generated from operations which will enable the Company to achieve a profitable level of operations.

If anticipated operating results are not achieved, management has the intent, and believes it has the ability, to further delay or reduce expenditures. In such case, the further reduction in operating expenses might need to be substantial. Failure to generate sufficient cash flows from operations, raise additional capital, or reduce certain discretionary spending would have a material adverse effect on the Company’s ability to achieve its intended business objectives. The Company can give no assurance that it will be successful in its plans and can give no assurance that additional financing will be available on terms advantageous to the existing terms or that additional financing will be available at all. Should the Company not be successful in obtaining the necessary financing to fund its operations, the Company would need to curtail certain or all of its operational activities and/or contemplate the sale of its assets if necessary.
