During the second quarter of fiscal year 2026, as a result of reduced earnings forecasts of the IoT Connected Services reporting unit, the Company performed an interim impairment test using a quantitative assessment of the IoT Connected Services reporting unit, included in the IoT Systems and Connectivity operating segment. The interim impairment test resulted in $42.0 million of total pre-tax non-cash goodwill impairment charges for the IoT Connected Services reporting unit recorded in the Statements of Operations during the second quarter of fiscal year 2026. The fair value of the reporting unit was determined based on a discounted cash flow model (an income approach) and earnings multiples (a market approach). Significant inputs to the reporting unit fair value measurements included forecasted cash flows, discount rates, terminal growth rates and earnings multiples, which were determined by management estimates and assumptions. The reporting unit fair value measurement is classified as Level 3 in the fair value hierarchy because it involves significant unobservable inputs.
Goodwill is not amortized, but is tested for impairment at the reporting unit level using either a qualitative or quantitative assessment on an annual basis during the fourth quarter of each fiscal year, and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment of goodwill is measured at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair market value of the reporting unit. As of October 26, 2025, there was no indication of impairment of the Company's goodwill balances.

Amortization expense of finite-lived intangible assets related to core technologies was recorded in "Amortization of acquired technology" within "Total cost of sales" in the Statements of Operations, and amortization expense of finite-lived intangible assets related to customer relationships and trade name was recorded in "Intangible amortization" within "Total operating expenses, net" in the Statements of Operations. Amortization expense of finite-lived intangible assets related to software licenses was recorded in "Cost of sales" in the Statements of Operations and amortization expense of finite-lived intangible assets related to capitalized development costs was recorded in "Product development and engineering" in the Statements of Operations.
