[1] | As discussed in Note 17 - "Subsequent Events," on March 24, 2016, the Company entered into an amendment to its Amended Loan Agreement (see discussion below), dated October 31, 2011, with PNC Bank, National Association ("PNC") which extended the due date of our current Credit Facility from October 31, 2016 to March 24, 2021 (the amendment, together with the Amended Loan Agreement, is collectively known as the "Revised Loan Agreement"). Pursuant to the Revised Loan Agreement, the revolving line of credit is to remain at up to $12,000,000 (subject to the amount of borrowings based on a percentage of eligible receivables as previously defined under the Amended Loan Agreement) with the term loan revised to $6,100,000, with monthly payment of approximately $102,000. In accordance with ASC 470, "Debt," this post balance-sheet date agreement demonstrated the Company's ability to refinance its short-term obligations on a long-term basis; therefore, the Company has reclassified the current portion of the outstanding debt to long-term except for $1,486,000 in principal payments that will be due by December 31, 2016 (see Note 17 - "Subsequent Events" for further details of this Revised Loan Agreement).
