12. Liquidity and Going Concern

The Company believes its cash of $89.9 million, as of September 30, 2017, will be sufficient to fund the Company’s current operating plan for at least twelve months from date of filing. The Company may need to raise additional funds in order to execute the current operating plan in the future. There can be no assurance that the Company will be able to obtain future additional debt, equity financing, or generate product revenue or revenues from collaborative partners, on terms acceptable to the Company, on a timely basis or at all. The failure of the Company to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on the Company’s business, results of operations, and financial condition.
