Note 2. Going Concern and Management Plans

The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As of September 30, 2019, the Company had working capital of $21.7 million and an accumulated deficit of $76.5 million. Since inception, the Company has recorded approximately $1.1 million and $2.4 million of revenue from contract research and government grants, and microelectromechanical systems ("MEMS") foundry and engineering review services, respectively. As of November 01, 2019, the Company had cash and cash equivalents of $21.1 million. The Company estimates that cash on hand is not sufficient to fund its operations for the next 12 months. Therefore, the Company will need to obtain additional capital to fund operations past that date. The Company is actively managing and controlling cash outflows to mitigate this risk. However, this matter raises substantial doubt about the Company's ability to continue as a going concern within one year from the date of this filing. These condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of asset amounts or the classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

There is no assurance that the Company's projections and estimates are accurate. The Company's primary sources of funds for operations since inception have been contract research and government grants, MEMS Foundry and Engineering services revenue, sales of our equity securities, and issuance of debt. The Company needs to obtain additional capital to accomplish its business plan objectives and will continue its efforts to secure additional funds. However, the amount of funds raised, if any, may not be sufficient to enable the Company to attain profitable operations. To the extent that the Company is unsuccessful in obtaining additional financing, the Company may need to curtail or cease its operations and implement a plan to extend payables or reduce overhead until sufficient additional capital is raised to support further operations. There can be no assurance that such a plan will be successful.
