Use of Estimates

The preparation of unaudited consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Significant estimates are associated with recording accounts receivable, inventories, goodwill, intangible assets other than goodwill, contingent consideration liabilities related to business combinations, long-lived assets, derivative financial instruments, deferred income taxes, warranty obligations, revenue over time, and stock-based compensation expense. The Company assesses the estimates on an ongoing basis and records changes in estimates in the period they occur and become known. Actual results could differ from these estimates.

The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, including results of operations and financial condition will depend on future developments that are highly uncertain. This includes results from new information that may emerge concerning COVID-19 and any actions taken to contain or treat COVID-19, as well as the economic impact on local, regional, national and international customers and markets. The Company has made estimates of the impact of COVID-19 within the analysis of its financial statements.

Foreign Currency Translation

Certain transactions of the Company and its subsidiaries are denominated in currencies other than their functional currency. Foreign currency exchange gains (losses) generated from the settlement and remeasurement of these transactions are recognized in earnings and presented within “Other income (expenses)” in the Company’s Consolidated Statements of Operations. Net foreign currency transaction and remeasurement losses were $0.9 million and $1.2 million for the three months ended March 31, 2023 and 2022, respectively. Net foreign currency transaction and remeasurement losses were $0.8 million and $3.2 million during the six months ended March 31, 2023 and 2022, respectively.

The determination of the functional currency of the Company’s subsidiaries is based on their financial and operational environment and is the local currency of the Company’s foreign subsidiaries. The subsidiaries’ assets and liabilities are translated into the reporting currency at period-end exchange rates, while revenue, expenses, gains and losses are translated at the average exchange rates during the period. Gains and losses from foreign currency translations are recorded in “Accumulated other comprehensive income (loss)” in the Company’s Consolidated Balance Sheets and

presented as “Foreign currency translation adjustments” in the Company’s Consolidated Statements of Comprehensive Income (Loss).

Hedging Activities

On February 1, 2022, the Company entered into a cross-currency swap agreement to hedge the variability of exchange rate impacts between the U.S. dollar and the Euro. Under the terms of the cross-currency swap agreement, the Company notionally exchanged approximately $1.03 billion for approximately €915 million at a weighted average interest rate of approximately 1.196%. The designated notional amount is $960 million and the actual interest rate is 1.283%. The 1.283% rate was in the range of the market value for that day and is the true interest rate on the notional amount. The Company designated the cross-currency swap as a hedge of net investments against one of our Euro denominated subsidiaries which requires an exchange of the notional amounts at maturity. At the maturity of the cross currency-swap on February 1, 2023, the Company delivered a notional amount of €852 million and received a notional amount of $960 million at an exchange rate of 1.1261, which includes realization of a gain of $29.3 million, which was recorded in “Accumulated other comprehensive income (loss)”.

On February 1, 2023, the Company entered into another cross-currency swap agreement to hedge the variability of exchange rate impacts between the U.S. dollar and the Euro. Under the terms of the cross-currency swap agreement, the Company notionally exchanged approximately $436 million for approximately €400 million at a weighted average interest rate of approximately 1.66%. The Company designated the cross-currency swap as a hedge of net investments against one of its Euro denominated subsidiaries, which requires an exchange of the notional amounts at maturity on February 1, 2024.

The cross-currency swaps are marked to market at each reporting period, representing the fair values of the cross-currency swap and any changes in fair value are recognized as a component of “Accumulated other comprehensive items, net,” on the Consolidated Statements of Comprehensive Income (Loss). Interest accrued on the cross-currency swap is recorded within “Interest income” on the Consolidated Statements of Operations. For the three and six months ended March 31, 2023, the Company recorded a net loss of $13.1 and $70.3 million, respectively to “Accumulated other comprehensive income (loss)” and recorded “Interest income” of $2.2 million and $5.3 million on these instrument for the three and six months ended March 31, 2023, respectively.

Accounts Receivable and Allowance for Expected Credit Losses and Sales Returns

Trade accounts receivable do not bear interest and are recorded at the invoiced amount. The Company maintains an allowance for expected credit losses representing its best estimate of expected credit losses related to its existing accounts receivable and their net realizable value. The Company determines the allowance based on a number of factors, including an evaluation of customer credit worthiness, the age of the outstanding receivables, economic trends, historical experience and other information over the payment periods. The Company reviews and adjusts the allowance for expected credit losses on a quarterly basis. Accounts receivable balances are written off against the allowance for expected credit losses when the Company determines that the balances are not recoverable. Provisions for expected credit losses are recorded in “Selling, general and administrative” expenses in the Consolidated Statements of Operations. The Company determines the allowance for sales returns based on its best estimate of expected customer returns. Provisions for sales returns are recorded in “Revenue” in the Consolidated Statements of Operations. The Company does not have any off-balance-sheet credit exposure related to its customers.

Recently Adopted Accounting Pronouncements

In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832) – Disclosures by Business Entities about Government Assistance. The amendment in this ASU requires disclosures to increase the transparency of transactions with a government accounted for by applying a grant or contribution accounting model by analogy, including (1) the types of transactions, (2) the accounting for those transactions, and (3) the effect of those transactions on an entity’s financial statements. This ASU is effective for annual periods beginning after December 15, 2021. The Company will adopt the provisions of this ASU in fiscal 2023.

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. ASU 2021-08 requires an entity to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Under current GAAP, an acquirer generally recognizes such items at fair value on the acquisition date. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted. The standard should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The Company adopted the guidance during the first quarter of fiscal year 2022. The impact of the adoption of this ASU is immaterial to the Company’s consolidated financial statements.

In October 2020, the FASB issued ASU 2020-10, Codification Improvements. The amendments in this ASU represent changes to clarify certain ASCs, correct unintended application of guidance, or make minor improvements to certain ASCs that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities.

significant gains and losses, and an explanation of any other significant changes in the benefit obligation or plan assets. The amendment removes disclosure requirements for accumulated other comprehensive income or loss expected to be recognized over the next year, information about plan assets to be returned to the entity, and the effects of a one-percentage-point change on the assumed health care costs and the effect of this change in rates on service cost, interest cost, and the benefit obligation for postretirement health care benefits.
