Debt Disclosure [Abstract]
Note Payable	Note 3 – Note Payable On April 17, 2020, we entered into a promissory note (the “Note”) with City National Bank, the lender, evidencing an unsecured loan pursuant to the U.S. Small Business Administration (“SBA”) Paycheck Protection Program (“PPP”) of the Coronavirus Aid, Relief, and Economic Security Act of 2020 (the “CARES Act”) of approximately $4.4 million (the “PPP Loan”). We applied for and received the PPP Loan pursuant to the then published PPP qualification and certification requirements. On April 23, 2020, the SBA, in consultation with the Department of Treasury, issued new guidance that created uncertainty regarding the qualification requirements for a PPP Loan (the “New Guidance”). In light of the New Guidance, we determined it appropriate to pay off the entire amount of the PPP Loan. Accordingly, on May 12, 2020, we paid off in full the principal and interest on the PPP Loan, resulting in the termination of the Note.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.
