All issued and outstanding common stock, options exercisable for common stock, warrants exercisable for common stock, restricted stock units, and per share amounts contained in the Company’s condensed consolidated financial statements have been retroactively adjusted to reflect this reverse stock split for all periods presented. As a result of the sale of the International Business, the Company has retrospectively revised the consolidated statements of operations for the three months ended March 31, 2016, to reflect the financial results from the International Business, and the related assets and liabilities, as discontinued operations. The Company’s Board approved annual operating plan projects that its existing working capital at March 31, 2017 of $39.1 million (including cash of $25.5 million), allows the Company to fund its operations through one year subsequent to the date the financial statements are issued. The Company has incurred significant net losses since inception and has relied on its ability to fund its operations through revenues from the sale of its products, equity financings and debt financings. As the Company has historically incurred losses, successful transition to profitability is dependent upon achieving a level of revenues adequate to support the Company’s cost structure. This may not occur and, unless and until it does, the Company will continue to need to raise additional capital. Operating losses and negative cash flows may continue for at least the next year as the Company continues to incur costs related to the execution of its operating plan and introduction of new products. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern and do not include any adjustments that might result from the outcome of this uncertainty. A going concern basis of accounting contemplates the recovery of the Company’s assets and the satisfaction of its liabilities in the normal course of business.
