Our products are generally sold with standard warranty periods, which differ by product, ranging from 12 to 36 months. Parts and labor are typically covered under the terms of the warranty agreement. Our warranty expense accruals are based on historical and estimated costs by product and configuration. From time-to-time we offer customers extended warranties beyond the standard warranty period. In those situations, the revenue relating to the extended warranty is deferred at its estimated fair value and recognized on a straight-line basis over the contract period. Costs associated with our extended warranty contracts are expensed as incurred. Restructuring Costs We record restructuring activities including costs for one 420, Exit or Disposal Cost Obligations 420” . 420 712, Nonretirement Postemployment Benefits 4, Debt Issuance Costs We capitalize costs related to the issuance of debt.

Amortization related to deferred debt issuance costs and original discount costs was $49,000 and $0.1 million for the three April 1, 2023 March 26, 2022, Foreign Remeasurement and Currency Translation Assets and liabilities of our wholly owned foreign subsidiaries that use the U.S. Dollar as their functional currency are re-measured using exchange rates in effect at the end of the period, except for nonmonetary assets, such as inventories and property, plant and equipment, which are re-measured using historical exchange rates. Revenues and costs are re-measured using average exchange rates for the period, except for costs related to those balance sheet items that are re-measured using historical exchange rates. Gains and losses on foreign currency transactions are recognized as incurred. During the three April 1, 2023, three March 26, 2022, Certain of our foreign subsidiaries have designated the local currency as their functional currency and, as a result, their assets and liabilities are translated at the rate of exchange at the balance sheet date, while revenue and expenses are translated using the average exchange rate for the period. Cumulative translation adjustments resulting from the translation of the financial statements are included as a separate component of stockholders’ equity. Foreign Exchange Derivative Contracts We operate and sell our products in various global markets. As a result, we are exposed to changes in foreign currency exchange rates. We enter into foreign currency forward contracts with a financial institution to hedge against future movements in foreign exchange rates that affect certain existing U.S. Dollar denominated assets and liabilities held at our subsidiaries whose functional currency is the local currency. For accounting purposes, our foreign currency forward contracts are not 7, Share-Based Compensation We measure and recognize all share-based compensation under the fair value method.

Diluted income per share includes the dilutive effect of common shares potentially issuable upon the exercise of stock options, vesting of outstanding restricted stock and performance stock units and issuance of stock under our employee stock purchase plan using the treasury stock method. In loss periods, potentially dilutive securities are excluded from the per share computations due to their anti-dilutive effect. For purposes of computing diluted income per share, stock options with exercise prices that exceed the average fair market value of our common stock for the period are excluded. For the three April 1, 2023, three March 26, 2022, The following table reconciles the denominators used in computing basic and diluted income per share (in thousands) Three Months Ended April 1, March 26, 2023 2022 Weighted average common shares 47,343 48,778 Effect of dilutive securities 828 791 48,171 49,569 Leases We determine if a contract contains a lease at inception. Operating leases are included in operating lease right of use (“ROU”) assets, current other accrued liabilities, and long-term lease liabilities on our condensed consolidated balance sheets. Finance leases are included in property, plant and equipment, other current accrued liabilities, and long-term lease liabilities on our condensed consolidated balance sheets.

As most of our leases do not The operating lease ROU asset also includes any lease payments made, lease incentives, favorable and unfavorable lease terms recognized in business acquisitions and excludes initial direct costs incurred and variable lease payments. Variable lease payments include estimated payments that are subject to reconciliations throughout the lease term, increases or decreases in the contractual rent payments, as a result of changes in indices or interest rates and tax payments that are based on prevailing rates. Our lease terms may Leases with an initial term of 12 not We sublease certain leased assets to third None Revenue Recognition Our net sales are derived from the sale of products and services and are adjusted for estimated returns and allowances, which historically have been insignificant. We recognize revenue when the obligations under the terms of a contract with our customers are satisfied; generally, this occurs with the transfer of control of our systems, non-system products or services. In circumstances where control is not Revenue for established products that have previously satisfied a customer’s acceptance requirements is generally recognized upon shipment. In cases where a prior history of customer acceptance cannot be demonstrated or from sales where customer payment dates are not Certain of our equipment sales have multiple performance obligations. These arrangements involve the delivery or performance of multiple performance obligations, and transfer of control of performance obligations may Unsatisfied performance obligations primarily represent contracts for products with future delivery dates.
