Short-term debt comprises a significant component of the Company’s funding needs. Short-term debt is generally defined as debt with principal maturities of one-year or less. Long-term debt is defined as principal maturities of one year or more.

We enter into promissory notes with third parties and company officers to support our operations. Promissory notes typically are for less than three years maturity and carry interest rates from 0% to 28.0%. For many of the notes listed above, the scheduled maturity date has passed, and we currently are in default of the matured loan. Company management is working with the creditors to remediate the $5,960,574 in promissory notes and loan advances that are in default. Promissory notes and loan advances that are in default still accrue interest after their scheduled maturity date. There are no financial covenants associated with the promissory notes and loan advances, and there are no compliance waivers that have been received from creditors. We record imputed interest on promissory notes and advances which are deemed to be below the market interest rate. For the years ended September 30, 2021 and 2020, we recorded interest expense of $21,168,232 and $18,094,234, respectively.
