The Company intends to fund any working capital requirements and capital commitments via cash at hand, cash flow from operations, new mortgage debt financing for the vessel under construction, debt balloon payment refinancing, proceeds from its at-the-market offering and other equity offerings. In the unlikely event that these are not sufficient, the Company may also draw down up to $4.00 million under a commitment from COLBY Trading Ltd., a company controlled by the Pittas family and affiliated with the Company’s Chief Executive Officer, and possible vessel sales (where equity will be released) or sale of the newbuilding contract itself, if required, among other options. The Company believes that it will have adequate funding through the sources described above and, accordingly, it believes it has the ability to continue as a going concern and finance its obligations as they come due over the next twelve months following the date of the issuance of these financial statements. Consequently, the interim condensed consolidated financial statements have been prepared on a going concern basis which contemplates the realization of assets and satisfaction of liabilities in the normal course of business.
