Debt Disclosure [Abstract]
Paycheck Protection Program Loan	(9) Paycheck Protection Program Loan As a result of the COVID-19 pandemic, on March 27, 2020, the U.S. Government passed into law the Coronavirus Aid, Relief and Economic Security Act, or the (“CARES Act”) which included the ability to secure loans under the Paycheck Protection Program (“PPP”). On May 3, 2020, after its application was submitted and approved, the Company signed a PPP loan with Santander Bank, N.A. (“Santander”) as the lender for $890,347 pursuant to the PPP under the CARES Act, as implemented by the U.S. Small Business Association (“SBA”). The PPP loan is an unsecured note with Santander as the lender and governed by a loan agreement with Santander. The interest rate is 1% and the loan is repayable over two years. The loan contains customary events of defaults relating to, among other things, payment defaults or breaches of the terms of the loan. Upon the occurrence of an event of default, the lender may require immediate repayment of all outstanding under the loan. Interest and principal payments are deferred for the first 6 months from the date of the loan. Principal and interest of approximately $49,000 are payable monthly commencing 6 months after the disbursement date and may be repaid by the Company at any time prior to maturity with no prepayment penalties. The Company received the proceeds on May 5, 2020. The SBA allows loan forgiveness for eligible costs incurred and paid which include (a) payroll costs, (b) interest on any real or personal property mortgage prior to February 15, 2020, (c) rent on any lease in force prior to February 15, 2020, and (d) utility payments for which service began before February 15, 2020. As of October 31, 2020, the Company has utilized all of the loan proceeds. While the Company currently believes that the use of the loan proceeds will meet the conditions for forgiveness of the loan and is in the process of preparing the SBA’s forgiveness application, no assurance can be provided that the Company will obtain forgiveness of the loan, in whole or in part. On June 5, 2020, the Paycheck Protection Program Flexibility Act (“PPPFA”) was signed into law. Among other changes, the PPPFA (a) reduced the amount of the loan required to be spent on payroll costs from 75% to 60%, (b) extended the covered period to 24 weeks from 8 weeks, (c) extended the repayment term of the PPP loan from 2 years to 5 years, and (d) increased the deferred payment date from 6 months to 10 months. For the loans disbursed before June 5, 2020, the PPPFA provides the option to opt for 24 weeks for spending the loan instead of 8 weeks. The Company opted for 24 weeks to spend the loan. The Company is accruing interest expense until the loan is forgiven or repaid. If the loan were not forgiven by the SBA and the Company decided to repay the loan over 2 years, the interest expense for this loan period would be immaterial.
