Property, plant and equipment, net, including improvements that significantly add to productive capacity or extend useful life, are stated at historical cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The Company periodically reviews the estimated useful lives of property, plant and equipment. Changes to estimated useful lives are recorded prospectively from the date of the change. Maintenance and repairs expenditures are charged to expense as incurred.

The Company continues to expand and optimize its global manufacturing capacities, such as by its recent expansion of operations at its Philippines location, as well as its recent acquisition of Crocus Technology International Corp. (“Crocus”). Through its expansion efforts, newly acquired machinery and equipment and continuous maintenance and evaluation of on-hand equipment, the Company recognized advancements in equipment quality indicating increased estimated useful lives. During its first quarter, periodic review of the estimated useful lives of long-lived assets, the Company determined that the useful lives of its machinery and equipment should be increased. Effective March 30, 2024, the Company increased the useful lives of a significant portion of its machinery and equipment from seven years to ten years. For the three-month period ended December 27, 2024, these changes decreased depreciation expense by $4,460, decreased interim income tax benefit by $4,580 and increased net loss by $120, and no change to net income (loss) per share.
