Commitments and Contingencies	Commitments and Contingencies Silicon Valley Bank Revolving Line of Credit As of July 31, 2020 and January 31, 2020, the Company maintained a revolving line of credit that matures in September 2020 and provided for aggregate borrowings of up to $50.0 million. Prior to the maturity date, the Company has the option, to borrow an aggregate amount not to exceed $15.0 million and convert the borrowing to a term loan (Term-Out Loan), provided that no prior event of default has occurred. The existing aggregate borrowing amount on the revolving line of credit is reduced by the amount of the Term-Out Loan. Principal payments on the Term-Out Loan are repaid in consecutive monthly installments. The maturity date is the earlier of (i) 48 months after such Term-Out Loan are made and (ii) September 2023. The applicable interest rate for borrowings under the revolving line of credit and the Term-Out Loan are determined as follows: for borrowings less than $5.0 million, the interest rate is based on the Wall Street Journal's Prime Rate plus a 0.5% margin. For borrowings greater than or equal to $5.0 million, but less than $10.0 million, the interest rate is based on the Wall Street Journal's Prime Rate. For borrowings greater or equal to $10.0 million, the interest rate is based on the Wall Street Journal's Prime Rate minus a 0.5% applicable margin. Standby letters of credit related to the Company's office lease facilities of $4.7 million and $3.5 million were outstanding as of July 31, 2020 and January 31, 2020, respectively, and such amounts reduce aggregate borrowings available under the revolving line of credit.
