[1] During the year ended December 31, 2025, the Company determined that certain machinery previously assigned to the Re-Tain® business no longer had a future use to the Company or any specific undiscounted cash flows other than estimated proceeds from the expected sale. As a result, the Company recognized an impairment charge on the machinery to write-down their cost to their estimated fair value.
