All Dortmund Fab assets and liabilities were recorded in the Electronics segment and are primarily reflected in the Europe geographic area. The goodwill resulting from this acquisition consists largely of the Company’s expected future product sales and synergies from combining Dortmund Fab’s products and technology with the Company’s existing semiconductor products portfolio. Goodwill resulting from the Dortmund Fab acquisition is expected to be deductible for tax purposes. 
During the three months ended June 28, 2025, the Company recorded measurement period adjustments to decrease other current assets of $ million and deferred tax liability of $ million. As a result of these adjustments, goodwill was increased by $ million accordingly. In addition, the Company made a reclassification adjustment of $ million between current liabilities and other long-term liabilities. The total impact of the adjustment to Cost of sales was $ million in the three months ended June 28, 2025. 
 million and $ million, respectively, and loss before income taxes was $ million and $ million, respectively, since the December 31, 2024 acquisition of Dortmund Fab.
As required by purchase accounting guidance, the Company recorded a $ million step-down of inventory to its fair value as of the acquisition date based on the preliminary valuation. The step-down was fully amortized as a non-cash credit to cost of sales during the first fiscal quarter of 2025 as the acquired inventory was sold and reflected as other non-segment costs.
During the six months ended June 29, 2024, the Company incurred approximately $ million of legal and professional fees related to the Dortmund Fab acquisition recognized as Selling, general, and administrative expenses in the Condensed Consolidated Statements of Net Income. A total of $ million of legal and professional fees related to the Dortmund Fab acquisition was recognized since 2023. These costs were reflected as other non-segment costs.

Mutual Funds
 
The Company has a non-qualified Supplemental Retirement and Savings Plan which provides additional retirement benefits for certain management employees and named executive officers by allowing participants to defer a portion of their annual compensation. The Company maintains accounts for participants through which participants make investment elections. The marketable securities are classified as Level 1 under the fair value hierarchy as they are maintained in mutual funds with readily determinable fair value and recorded in Other long-term assets in the Condensed Consolidated Balance Sheets.
 
There were no changes during the quarter ended June 28, 2025 to the Company’s valuation techniques used to measure asset and liability fair values on a recurring basis. As of June 28, 2025 and December 28, 2024, the Company did not hold any non-financial assets or liabilities that are required to be measured at fair value on a recurring basis.

In addition to the methods and assumptions used for the financial instruments recorded at fair value as discussed above, the following methods and assumptions are used to estimate the fair value of other financial instruments that are not marked to market on a recurring basis. The Company’s other financial instruments include cash and cash equivalents, short-term investments, accounts receivable and its long-term debt. Due to their short-term maturity, the carrying amounts of cash and cash equivalents, short-term investments and accounts receivable approximate their fair values. The Company’s revolving and term loan debt facilities' fair values approximate book value at June 28, 2025 and December 28, 2024, as the rates on these borrowings are variable in nature. The purchase price of business acquisitions is primarily allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the acquisition date, with the excess recorded as goodwill. The Company utilizes Level 3 inputs in the determination of the initial fair value for certain assets acquired and liabilities assumed in business acquisitions.

The Company expects to make approximately $ million of contributions to the plans and pay $ million of benefits directly in 2025.
On October 4, 2024, the Company entered into a definitive agreement to purchase a group annuity contract, under which an insurance company is required to pay pension payments to the Company’s United Kingdom pension plan to match required pension payments until a later buyout, at which point the insurance company will directly pay and administer the benefits to the plan's participants, or to their designated beneficiaries. The purchase of this group annuity contract will reduce the Company’s outstanding pension benefit obligation by approximately $ million, representing approximately % of the total obligations of the Company’s qualified pension plans, and will be funded with pension plan assets and additional cash on hand. In connection with this transaction, the Company currently expects to record a one-time non-cash settlement charge in 2026 estimated between $ million and $ million, reflecting the accelerated recognition of a portion of unamortized actuarial losses in the plan. The actual settlement charge could differ from this estimate due to final data and plan wind-up expenses.
The Company also sponsors certain post-employment plans in foreign countries and other statutory benefit plans. The Company recorded expense of $ million for each of the three months ended June 28, 2025 and June 29, 2024, respectively, and $ million for each of the six months ended June 28, 2025 and June 29, 2024, respectively, in Cost of sales and Other income, net within the Condensed Consolidated Statements of Net Income. The pre-tax losses amount recognized in other comprehensive income (loss) for these plans were $ million and $ million for the three months ended June 28, 2025 and June 29, 2024, respectively, and $ million and $ million for the six months ended June 28, 2025 and June 29, 2024, respectively.
