Substantial doubt about going concern, management's evaluation						In connection with preparing consolidated financial statements for the year ended December 31, 2018, management evaluated whether there were conditions and events, considered in the aggregate, that raised substantial doubt about the Company’s ability to continue as a going concern within one year from the date that the financial statements are issued. The Company considered the historical operating loss and negative cash flow from operating activities trends, including the positive trends occurring in the recent year. The Company evaluated its ability to meet its obligations as they become due within one year from the date that the financial statements are issued by considering the following: In May 2017, the Company raised $2.2 million of new capital in a private placement offering of its common stock. In September 2017, the Company closed on a $5.5 million preferred stock transaction which converted $2.8 million of long and short-term debt, and raised $2.7 million of new capital. On March 5, 2018, the Company raised $5.0 million of new capital in a private placement offering of its common stock. On May 3, 2018, the Company raised $7.0 million of new capital in a private placement offering of its common stock. On November 7, 2018, the Company raised $7.5 million of new capital in a private placement offering of its common stock. Following this transaction, $3.2 million of short and long-term debt was repaid. In addition to the recent capital raised, management also believes that the Company will generate enough cash from operations to satisfy its obligations for the next twelve months from the issuance date.
Common stock raised of new capital, value						$ 17,600,000	1,992,000
Preferred stock transaction				$ 5,500,000
Debt instrument, principal amount				2,800,000
New equity capital raised				$ 2,700,000
Repayments of debt	$ 3,200,000
Substantial doubt about going concern, management's plans, substantial doubt not alleviated						The Company will take the following actions if it starts to trend unfavorably to its internal profitability and cash flow projections, in order to mitigate conditions or events that would raise substantial doubt about its ability to continue as a going concern: Raise additional capital through short-term loans. Implement additional restructuring and cost reductions. Raise additional capital through a public or private placement. Secure a commercial bank line of credit. Dispose of one or more product lines. Sell or license intellectual property.
