Based on historical sales to this customer, management expects a total loss of sales of approximately $30 million or 55%. The termination of this relationship may negatively impact the Company’s financial condition and operating results. The Company continues to assess its customer concentration risk and is implementing strategic initiatives to broaden its customer base. In response, management plans to continue its efforts to expand the present market area and increase sales to its existing customers and seek new customer opportunities. Management also intends to continue to tighten control over all expenditures and an increased emphasis on inventory and production management.

Greystone and IBC are currently in negotiations to amend the Restated Loan Agreement, which includes curing the covenant violations. IBC has not exercised their rights to accelerate the maturity of the outstanding balance of the term loans. Management intends to renew the revolving loan at comparable terms and believes it is probable such renewal will be successful. Management believes that the successful execution of its business plan and debt modifications would alleviate the substantial doubt about the Company’s ability to continue as a going concern. However, there can be no assurance that these plans will be successful. Because it is unclear whether the Company will be successful in accomplishing these objectives, there is uncertainty about the Company’s circumstances, which creates substantial doubt about its ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might be necessary should the Company be unable to continue as a going concern.
