NOTES RECEIVABLE, NET	7. NOTES RECEIVABLE, NET In connection with the sale of the transformer business units in August 2019 (the “Equity Transaction”), amongst other consideration, we received two subordinated promissory notes in the aggregate principal amount of $5.0 million and $2.5 million, for a total aggregate principal amount of $7.5 million (the “Seller Notes”), subject to certain adjustments. The Seller Notes accrue interest at a rate of 4.0% per annum, with a final payment of all unpaid principal and interest becoming fully due and payable at December 31, 2022. The Company determined the fair value of the Seller Notes based on market conditions and prevailing interest rates. During the fourth quarter of 2019, the Company and the Buyer, pursuant to the Stock Purchase Agreement, completed the net working capital adjustment, which resulted in the Company paying the Buyer $1.8 million in cash and reducing the principal amount of the $5.0 million Seller Note to $3.2 million. During the second quarter of 2020, the Company recognized an additional reduction to the principal amount of the Seller Note of $194 for a valid claim paid by the Buyer on behalf of the Company. On December 15, 2022, the Company received in excess of $6.2 million as a final payment of all unpaid principal and interest paying the Seller Notes in full.
