Debt Debt
2021 Promissory Note
In connection with the acquisition of Lyte, we entered into a note purchase agreement and completed the sale of an unsecured promissory note (the "2021 Promissory Note") with an original principal amount of $5,220 in a private placement that closed on October 18, 2021. The 2021 Promissory Note was sold with an original issue discount of $200 and we paid at closing issuance costs totaling $280. After deducting all transaction costs, net cash proceeds to the Company were $4,740. No interest will accrue on the 2021 Promissory Note unless and until the occurrence of an event of default (as defined in the 2021 Promissory Note). Beginning on January 15, 2022 and on the same day of each month thereafter until the 2021 Promissory Note is paid in full, we are required to make a monthly amortization payments in the amount of $574 until the maturity date of October 15, 2022. We may prepay any or all outstanding balance of the 2021 Promissory Note earlier than it is due with a prepayment premium of 110%. The prepayment premium also applies to the monthly amortization payments, which amounts to an effective interest rate of approximately 18%.
The 2021 Promissory Note had a principal balance of $2,088 and $5,220 and debt discount of $57 and $316 at June 30, 2022 and December 31, 2021, respectively.
