Substantial doubt about the company's ability to continue as a going concern.

“Accordingly, these conditions and events raise substantial doubt about the Company’s ability to continue as a going concern. ... Because the Company’s plans are dependent on obtaining additional financing and other actions that are not entirely within the Company’s control, management cannot conclude that such plans are probable of being effectively implemented and sufficient to alleviate the substantial doubt. Accordingly, substantial doubt about the Company’s ability to continue as a going concern has not been alleviated.”
