The Company’s fiscal year ends on the Saturday closest to September 30. The Company also uses a "4-4-5" weekly accounting system for the interim periods in each quarter. Each quarter, therefore, ends on a Saturday at the end of the 4-4-5 period. Periodically, an additional week must be added to the fiscal year to re-align with the Saturday closest to September 30. Fiscal 2024, fiscal 2023 and fiscal 2022 each included 52 weeks.

The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and notes thereto. The full extent to which current global events and economic conditions will impact the Company's business and operating results will depend on future developments that are highly uncertain and cannot be accurately predicted. The Company has considered information available as of the date of issuance of these financial statements and is not aware of any specific events or circumstances that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information becomes available. Actual results could differ materially from these estimates.

Cash and Cash Equivalents and Restricted Cash: Cash equivalents include short-term highly liquid investments and are classified as Level 1 in the fair value hierarchy described below. Cash equivalents of $60.9 million and $33.5 million at September 28, 2024 and September 30, 2023, respectively, consisted primarily of time deposits with initial maturities of less than three months. Restricted cash represents cash received from customers to settle invoices sold under accounts receivable purchase agreements that the Company continues servicing and is contractually required to be set aside. The restrictions will lapse when the cash is remitted to the purchaser of the receivables. Restricted cash is also classified as Level 1 in the fair value hierarchy described below.

Inventories: Inventories are valued at the lower of cost or net realizable value. Cost is determined by the first-in, first-out ("FIFO") method. Valuing inventories at the lower of cost or net realizable value requires the use of estimates and judgment. Customers may cancel their orders, change production quantities or delay production for a number of reasons that are beyond the Company’s control. Any of these, or certain additional actions, could impact the valuation of inventory. Any actions taken by the Company’s customers that could impact the value of its inventory are considered when determining the lower of cost or net realizable value.

Certain facilities and equipment held under finance leases are classified as property, plant and equipment and amortized using the straight-line method over the term of the lease and the related obligations are recorded as liabilities. Amortization of assets held under finance leases is included in depreciation expense (see Note 3, "Property, Plant and Equipment") and the financing component of the lease payments is classified as interest expense. Maintenance and repairs are expensed as incurred.

Impairment of Long-Lived Assets: Long-lived assets, including property, plant and equipment, operating lease right-of-use assets and intangible assets with finite lives are reviewed for impairment and written down to fair value when facts and circumstances indicate that the carrying value of long-lived assets or asset groups may not be recoverable through estimated future undiscounted cash flows. If an impairment has occurred, a write-down to estimated fair value is made and the impairment loss is recognized as a charge against current operations. The impairment analysis is based on management’s assumptions, including future revenue and cash flow projections. Circumstances that may lead to impairment of property, plant and equipment, operating lease right-of-use assets and intangible assets with finite lives include reduced expectations for future performance or industry demand and possible further restructurings, among others.

Revenue Recognition: Revenue is recognized over time for arrangements with customers for which: (i) the Company's performance does not create an asset with an alternative use to the Company, and (ii) the Company has an enforceable right to payment, including reasonable profit margin, for performance completed to date. Revenue recognized over time is estimated based on costs incurred to date plus a reasonable profit margin. If either of the two conditions noted above are not met to recognize revenue over time, revenue is recognized following the transfer of control of such products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying arrangement.

The Company recognizes revenue when a contract exists and when, or as, it satisfies a performance obligation by transferring control of a product or service to a customer. Contracts are accounted for when they have approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer.

The Company generally enters into a master services arrangement that establishes the framework under which business will be conducted. These arrangements represent the master terms and conditions of the Company's services that apply to individual orders, but they do not commit the customer to work with, or to continue to work with, the Company nor do they obligate the customer to any specific volume or pricing of purchases. Moreover, these terms can be amended in appropriate situations. Customer purchase orders are received for specific quantities with predominantly fixed pricing and delivery requirements. Thus, for the majority of our contracts, there is no guarantee of any revenue to the Company until a customer submits a purchase order. As a result, the Company generally considers its arrangement with a customer to be the combination of the master services arrangement and the purchase order. Most of the Company's arrangements with customers create a single performance obligation as the promise to transfer the individual manufactured product or service is capable of being distinct.

The Company’s performance obligations are satisfied over time as work progresses or at a point in time. A performance obligation is satisfied over time if the Company has an enforceable right to payment, including a reasonable profit margin. Determining if an enforceable right to payment includes a reasonable profit margin requires judgment and is assessed on a contract-by-contract basis.

For contracts requiring over time revenue recognition, the selection of the method to measure progress toward completion requires judgment and is based on the nature of the products or services to be provided. The Company uses a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress towards completion is measured based on the costs incurred to date.

The Company does not allow for a general right of return. Net sales include amounts billed to customers for shipping and handling and out-of-pocket expenses. The corresponding shipping and handling costs and out-of-pocket expenses are included in cost of sales. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from net sales.

Net sales from engineering design and development services, which are generally performed under contracts with a duration of twelve months or less, are typically recognized as program costs incurred by utilizing the proportional performance model. The completed performance model is used if certain customer acceptance criteria exist. Any losses are recognized when anticipated. Net sales from engineering design and development services were less than 5% of consolidated net sales for each of fiscal 2024, 2023 and 2022.

Income Taxes: Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company maintains valuation allowances when it is more likely than not that all or a portion of a deferred tax asset will not be realized. In determining whether a valuation allowance is required, the Company takes into account such factors as prior earnings history, expected future earnings, carryback and carryforward periods, and tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset.

Foreign Currency Translation & Transactions: The Company translates assets and liabilities of subsidiaries operating outside of the U.S. with a functional currency other than the U.S. dollar into U.S. dollars using exchange rates in effect at the relevant balance sheet date and net sales, expenses and cash flows at the average exchange rates during the respective periods. Adjustments resulting from the translation of the financial statements are recorded as a component of "Accumulated other comprehensive income (loss)." Exchange gains and losses arising from transactions denominated in a currency other than the functional currency of the entity involved and remeasurement adjustments for foreign operations where the U.S. dollar is the functional currency are included in the Consolidated Statements of Comprehensive Income as a component of "Miscellaneous, net." Exchange losses on foreign currency transactions were $3.4 million, $1.8 million and $0.7 million for fiscal 2024, 2023 and 2022, respectively. These amounts include the amount of gain recognized in income during each fiscal year due to forward currency exchange contracts entered into to hedge recognized assets or liabilities ("non-designated hedges") the Company entered into during each respective year. Refer to Note 5, "Derivatives and Fair Value Measurements," for further details on derivatives.

Derivatives: All derivatives are recognized on the balance sheets at fair value. The Company periodically enters into forward currency exchange contracts and interest rate swaps. On the date a derivative contract is entered into, the Company designates the derivative as a non-designated hedge or a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (a "cash flow" hedge). The Company does not enter into derivatives for speculative purposes. Changes in the fair value of non-designated derivatives are recorded in earnings as are the gains or losses related to the hedged asset or liability. Changes in the fair value of a derivative that qualifies as a cash flow hedge are recorded in "Accumulated other comprehensive income (loss)" within shareholders' equity until earnings are affected by the variability of cash flows. Certain forward currency exchange contracts are treated as cash flow hedges and, therefore, $16.1 million, $1.1 million and $(5.0) million was recorded in "Accumulated other comprehensive income (loss)" for fiscal 2024, 2023 and 2022, respectively. See Note 5, "Derivatives and Fair Value Measurements," for further information.

Earnings Per Share: The computation of basic earnings per common share is based upon the weighted average number of common shares outstanding and net income. The computation of diluted earnings per common share reflects additional dilution from share-based awards, excluding any with an antidilutive effect. See Note 7, "Earnings Per Share," for further information.

Share-based Compensation: The Company measures all grants of share-based payments to employees, including grants of employee stock options, at fair value and expenses them in the Consolidated Statements of Comprehensive Income over the service period (generally the vesting period) of the grant. See Note 9, "Benefit Plans," for further information.

Fair Value of Financial Instruments: The Company holds financial instruments consisting of cash and cash equivalents, restricted cash, accounts receivable, certain deferred compensation assets held under trust arrangements, accounts payable, debt, derivatives and finance and operating lease obligations. The carrying values of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and finance and operating lease obligations as reported in the consolidated financial statements approximate fair value. Derivatives and certain deferred compensation assets held under trust arrangements are recorded at fair value. Accounts receivable are reflected at net realizable value based on anticipated losses due to potentially uncollectible balances. Anticipated losses are based on management’s analysis of historical losses and changes in customers’ credit status. The fair value of the Company’s debt excluding finance lease and other financing obligations was $197.8 million and $374.3 million as of September 28, 2024 and September 30, 2023, respectively. The carrying value of the Company's debt was $200.0 million and $383.0 million as of September 28, 2024 and September 30, 2023, respectively. The Company uses quoted market prices when available or discounted cash flows to calculate fair value. If measured at fair value in the financial statements, long-term debt (including the current portion) would be classified as Level 2 in the fair value hierarchy described below. The fair values of the Company’s derivatives are disclosed in Note 5, "Derivatives and Fair Value Measurements." The fair values of the deferred compensation assets held under trust arrangements are discussed in Note 9, "Benefit Plans."

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (or exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The accounting guidance establishes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. The input levels are:

Business and Credit Concentrations: Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents, trade accounts receivable and derivative instruments, specifically related to counterparties. In accordance with the Company’s investment policy, the Company’s cash, cash equivalents and derivative instruments were placed with recognized financial institutions. The Company’s investment policy limits the amount of credit exposure in any one issue and the maturity date of the investment securities that typically comprise investment grade short-term debt instruments. Concentrations of credit risk in accounts receivable resulting from sales to major customers are discussed in Note 11, "Reportable Segments, Geographic Information and Major Customers". The Company, at times, requires cash deposits for services performed. The Company also closely monitors extensions of credit.

In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280), which requires enhanced disclosures for segment reporting. The guidance is effective for the Company beginning in the fourth quarter of fiscal 2025. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740), which requires enhanced disclosures for income taxes. The guidance is effective for the Company beginning in the first quarter of fiscal 2026. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures.

In March 2024, the SEC adopted final rules to require registrants to disclose certain climate-related information in registration statements and annual reports. The SEC stayed its climate disclosure rules to facilitate the orderly judicial resolution of pending legal challenges. We are currently evaluating the impacts that the SEC's rule will have on our financial statement disclosures.

In November 2024, the FASB issued ASU 2024-03 Disaggregation of Income Statement Expense (Subtopic 220-40), which requires disaggregated information about certain income statement expense line items. The guidance is effective for the Company beginning in fiscal 2028. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures.
