Note receivable [Abstract]
Note receivable	3. Note receivable The note receivable balance relates to a loan given to a third party with an interest rate of 4.5%, which was due in April 2020. The note includes a lender recourse provision that enables us to apply payments that would have been due to the third party under a previously signed long-term royalty agreement towards the loan balance. A $100 thousand royalty fee is scheduled to be paid to the third party in January 2021 that will instead be applied towards the note receivable balance as it becomes due. As a result, $100 thousand of the balance was classified as current and the remaining $1.5 million is expected to be reduced thereafter using the lender recourse provision. Notes receivable are stated at unpaid balances and interest income is recognized on the accrual method. In March 2020, we loaned an additional $600 thousand to the third party. For the three and six months ended June 30, 2020 we recorded $18 thousand and $31 thousand of interest income, respectively. As of June 30, 2020, we have no allowances for loan losses, unamortized deferred loan fees or unearned discounts.
