Notes Payable [Abstract]
7. NOTES PAYABLE	During the year ended September 30, 2017, the Company issued two series of convertible notes to individual investors, Series MM and Series NN (the Notes). The Notes had an aggregate principal amount of $1.5 million and $1.2 million, respectively, bore interest at 4% and were originally due on December 22, 2017. At the option of the note holders, the Series MM Notes could be converted into shares of the Company’s common stock at a fixed conversion rate of $1.69 and the Series NN Notes could be converted into shares of the Company’s common stock at a fixed conversion rate of $2.29. The purchasers of the convertible notes also received Series MM and Series NN warrants which allow the purchasers to acquire up to 893,491 and 539,300 shares of the Company’s common stock, respectively. The Series MM warrants are exercisable at a price of $1.86 per share and expire on June 22, 2022. The Series NN warrants are exercisable at a price of $2.52 per share and expire on July 24, 2022.A trust in which Geert Kersten, the Company’s Chief Executive Officer, holds a beneficial interest participated in the offering and purchased a note in the principal amount of $250,000. Patricia B. Prichep, the Company’s Senior Vice President of Operations, participated in the offering and purchased a note in the principal amount of $25,000. Upon issuance, the Company allocated proceeds received to the Notes and warrants on a relative fair value basis. As a result of such allocation, the Company determined the initial carrying value of the Notes to be approximately $1.6 million, the Series MM warrants to be approximately $0.6 million, the Series NN warrants to be approximately $0.5 million, and recorded a debt discount in the amount of approximately $1.1 million. Pursuant to the guidance in ASC 815-40, Contracts in Entity’s Own Equity, the Company evaluated whether the conversion feature of the note needed to be bifurcated from the host instrument as a freestanding financial instrument. Under ASC 815-40, to qualify for equity classification (or non-bifurcation, if embedded) the instrument (or embedded feature) must be both (1) indexed to the issuer’s own stock and (2) meet the requirements of the equity classification guidance. Based upon the Company’s analysis, it was determined the conversion option is indexed to its own stock and also met all the criteria for equity classification. Accordingly, the conversion option is not required to be bifurcated from the host instrument as a freestanding financial instrument. Since the conversion feature meets the equity scope exception from derivative accounting, the Company then evaluated whether the conversion feature needed to be separately accounted for as an equity component under ASC 470-20, Debt with Conversion and Other Options. Based upon the Company’s analysis, it was determined that a beneficial conversion feature existed as a result of the reduction in the face value of the Series MM and NN Notes, due to a portion of proceeds being allocated to the related warrants, and thus the conversion features needed to be separately accounted for as an equity component. The Company recorded beneficial conversion features relating to the Series MM and NN notes of approximately $603,000 and $506,000, respectively, which were also recorded as debt discounts. On October 30, 2017, the Company extended the due dates of the Notes from December 22, 2017 to September 21, 20l8, and issued the note holders 583,057 of Series RR Warrants. The Series RR warrants expire on October 30, 2022 and are exercisable at a price of $1.65 per share. These Series RR warrants are classified as equity warrants and are recorded at approximately $0.7 million, the fair value on the date of issuance. Because the Company was experiencing financial difficulties at the time of the modification and the creditors granted the Company a concession they would not have otherwise considered in the form of a lower effective interest rate, this modification was accounted for under ASC 470-60, “Troubled Debt Restructuring.” The Company calculated the future cash flows of the restructured debt to be greater than the carrying value of the debt and accounted for the change in debt prospectively, using the effective interest rate that equated the carrying amount to the future cash flows. The carrying value of the debt on the date of restructuring was approximately $0.7 million, which was net of a discount of approximately $1.6 million. The discount is being amortized to interest expense over the life of the Notes using the effective interest method. On June 11, 2018, all remaining outstanding Series MM and Series NN notes were converted into common stock in accordance with the original agreements resulting in notes in the principal amount of $1,860,000 being converted into 937,804 shares of common stock. As an inducement to convert, the Company issued the note holders 187,562 Series UU warrants The Series UU warrants are exercisable at a fixed price of $2.80 per share, are exercisable on December 11, 2018 and expire on June 11, 2020. Shares issuable upon the exercise of the warrants are restricted securities unless registered. The Company recognized an expense equal to the fair value of the consideration transferred in the transaction in excess of the fair value of consideration issuable under the original conversion terms. This expense represents the fair value of the Series UU warrants, which was calculated to be approximately $291,000 and is included as interest expense on the statement of operations. During the year ended September 30, 2018 and including the inducement, note holders converted all outstanding Notes in the principal amount of $2,294,300, into 1,166,105 shares of common stock. During the year ended September 30, 2017, note holders converted Notes in the principal amount of $450,700 into 266,686 shares of common stock. The unamortized debt discount relating to the converted notes was charged to interest expense. The total debt discount was amortized to interest expense using the effective interest method over the expected term of the Notes. During the years ended September 30, 2018 and 2017, the Company recorded approximately $2.0 million and $0.9 million in interest expense, respectively, relating to the amortization of the debt discount. At September 30, 2017, the remaining debt discount is approximately $1.3 million. On June 11, 2018, all note holders were given the option to receive the interest accrued on the Notes in cash or in shares converted at $2.80, the fair value of the shares on that date. Accrued interest in the amount of approximately $0.1 million was converted into 28,825 shares of common stock.

During the year ended September 30, 2017, the Company issued two series of convertible notes to individual investors, Series MM and Series NN (the Notes).

Pursuant to the guidance in ASC 815-40, Contracts in Entity’s Own Equity, the Company evaluated whether the conversion feature of the note needed to be bifurcated from the host instrument as a freestanding financial instrument. Under ASC 815-40, to qualify for equity classification (or non-bifurcation, if embedded) the instrument (or embedded feature) must be both (1) indexed to the issuer’s own stock and (2) meet the requirements of the equity classification guidance.

Since the conversion feature meets the equity scope exception from derivative accounting, the Company then evaluated whether the conversion feature needed to be separately accounted for as an equity component under ASC 470-20, Debt with Conversion and Other Options. Based upon the Company’s analysis, it was determined that a beneficial conversion feature existed as a result of the reduction in the face value of the Series MM and NN Notes, due to a portion of proceeds being allocated to the related warrants, and thus the conversion features needed to be separately accounted for as an equity component.
