Notes Payable and Capital Lease Obligations (Textual) |  |  |  |  |  |
Debt instrument principal, description |  | Michael Taglich, Robert Taglich and Taglich Brothers (collectively, the "Taglich Parties") owned $1,300,000, $650,000 and $382,000, respectively, principal amount of 8% Notes, with accrued interest thereon from the date of issuance through September 30, 2018 of $203,613, $120,097 and $68,294, respectively. In consideration for waiving all defaults in payment of principal and accrued interest on the 8% Notes through the date of the amendment, the conversion price of the Amended Notes owned by the Taglich Parties and the other holders of the Amended Notes has been reduced to $1.50 per share, subject to the anti-dilution adjustments set forth in the Amended Notes and the 8% Notes, and the Company issued to the Taglich Parties and the other holders of the 8% Notes such number of shares of common stock calculated based upon a value of $1.39 per share, the closing market price of common stock on the NYSE American on September 28, 2018, the date immediately prior to the date the holders of a majority of the outstanding principal amount of the 8% Notes approved the amendment as is equal to the interest accrued on their 8% Notes from the date of issuance through September 30, 2018. Based on the amended conversion price, if these notes were to be converted additional shares would be issued of common stock, and therefore further reduce the Company's earnings per share.. As a result, the Company issued to Michael Taglich, Robert Taglich and Taglich Brothers 146,484 shares, 86,401 shares and 49,132 shares, respectively, of common Stock. From and after September 30, 2018, interest on the unpaid principal amount of the Amended Notes shall accrue and be paid at the rate of six (6%) percent per annum, if paid in cash, or at the rate of eight (8%) percent per annum if converted into common stock. |  |  |  |
Interest on unpaid principal amount, description |  | From and after September 30, 2018, interest on the unpaid principal amount of the Amended Notes shall accrue and be paid at the rate of six (6%) percent per annum, if paid in cash, or at the rate of eight (8%) percent per annum if converted into common stock. |  |  |  |
Adoption of amendments, description |  | The Company agreed to pay Taglich Brothers $95,550, representing a fee equal to 2% of the outstanding principal amount of Notes whose registered holders (other than Taglich Brothers) received shares of common stock in lieu of cash payment of accrued interest on the 8% Notes as of September 30, 2018. |  |  |  |
Majority of outstanding principal amount, description |  | In September 2018, holders of a majority of the outstanding principal amount of the 8% Notes consented to an amendment to the terms of the 8% Notes to extend the maturity date to December 31, 2020 and to provide that interest on the 8% Notes, as amended (the "Amended Notes"), shall accrue and be paid on the due date of the Amended Notes or, if earlier, upon conversion of the Amended Notes into shares of common stock. |  |  |  |
