Note 4.Revolving Line of Credit

On August 1, 2015, the Company entered into an amendment to the Second Amended and Restated Loan Agreement (as amended, the “Loan Agreement”) with Midland States Bank to extend the term of the Company’s revolving line of credit to August 1, 2016. The credit facility consists of a single revolving note for up to $2 million with Midland States Bank, with borrowings limited to a borrowing base determined based on 70 percent to 80 percent of eligible accounts receivable plus 50 percent of eligible inventory. Significant restrictive covenants in the Loan Agreement include prohibitions on any merger, consolidation or sale of all or a substantial portion of the Company’s assets and limits on the payment of dividends or the repurchase of shares. The Loan Agreement does not contain any financial covenants that require compliance with ratios or amounts.  Dividends and share repurchases are permitted as long as after giving effect to the dividend or share repurchase the Company has a ratio of total liabilities to total stockholders’ equity of no more than 1:1.  Borrowings on the revolving note bear interest at the national prime rate published by the Wall Street Journal (3.25 percent at September 30, 2015).  The note is collateralized by substantially all of the assets of the Company. No amounts were outstanding under the revolving note at either September 30, 2015 or 2014.
