The primary factor that is currently influencing management’s estimate of expected credit losses is its knowledge of the status of certain customers’ development projects.

On January 7, 2025, the Company accepted a $10,000 note as a portion of the proceeds from the sale of certain excess equipment described in note 6. The note would have matured on July 7, 2026 and was payable by the note holder in whole or in part at any time prior to maturity without penalty or premium. Otherwise, it was scheduled to be collected as follows: $4,000 on July 7, 2025, $4,000 on January 7, 2026 and $2,000 on July 7, 2026.

The note was interest-free through July 7, 2025, and thereafter principal would have earned interest at the U.S. prime rate plus 1% until repayment. Management concluded that interest should have been imputed for the full duration of the note at an effective interest rate of 8.5%, representing the stated rate. As a result, the Company recorded an initial discount of $410 as an offset to the noncurrent portion of the note based on its maturity date at that time. In June 2025, the note holder paid the note in full.
