Hirsch International Corp. (HRSH) said Friday in its quarterly report that substantial doubt is raised as to its ability to continue as a going concern. The provider of equipment and education and support services to the graphic and decorated apparel industry incurred a significant loss last year and in the first quarter of 2009 and hasn't generated positive cash flow from operations. The company's management believes that current cash levels may not be sufficient to fund the company's operations through the foreseeable future and it is currently seeking a new credit facility.
