Jun. 30, 2023
Accounting Policies [Abstract] |
Principles of Consolidation and Basis of Presentation | Principles of Consolidation and Basis of Presentation The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and all entities where it has a controlling financial interest and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). All intercompany balances and transactions have been eliminated in consolidation. The accompanying year-end balance sheet was derived from audited financial statements but does not include all disclosures required by GAAP. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited financial statements and in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the Company’s financial position as of June 30, 2023, and the results of its operations for the three and nine months ended June 30, 2023 and 2022, and cash flows for the nine months ended June 30, 2023 and 2022, respectively. Certain information and disclosures normally included in the Company’s annual consolidated financial statements have been condensed or omitted and, accordingly, the accompanying financial information should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2022 filed with the U.S. Securities and Exchange Commission on November 25, 2022 (the “2022 Annual Report on Form 10-K”).
Use of Estimates | Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make certain estimates and assumptions that affect amounts reported in the financial statements and notes thereto. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results may differ from these estimates. 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. 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 in the analysis of its financial statements.
Business Combinations | Business Combinations The Company accounts for business acquisitions using the purchase method of accounting, in accordance with which assets acquired and liabilities assumed are recorded at their respective fair values at the acquisition date. The fair value of the consideration paid, including contingent consideration, is assigned to the assets acquired and liabilities assumed based on their respective fair values. Goodwill represents the excess of the purchase price over the estimated fair values of the assets acquired and liabilities assumed. Significant judgment is used in determining fair values of assets acquired and liabilities assumed and contingent consideration, as well as intangibles and their estimated useful lives. Fair value and useful life determinations may be based on, among other factors, estimates of future expected cash flows and appropriate discount rates used in computing present values. These judgments may materially impact the estimates used in allocating acquisition date fair values to assets acquired and liabilities assumed, as well as our current and future operating results. Actual results may vary from these estimates and may result in adjustments to goodwill and acquisition date fair values of assets and liabilities during a measurement period or upon a final determination of asset and liability fair values, whichever occurs first. Adjustments to fair values of assets and liabilities made after the end of the measurement period are recorded within our operating results. Changes in the fair value of contingent consideration resulting from a change in the underlying inputs are recognized in results of operations until the arrangement is settled.
Foreign Currency Translation | 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 (expense)” in the Condensed Consolidated Statements of Operations. Net foreign currency transaction and remeasurement gains were $0.1 million and $0.3 million for the three months ended June 30, 2023 and 2022, respectively. Net foreign currency transaction and remeasurement losses were $2.7 million and $2.9 million during the nine months ended June 30, 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 Condensed Consolidated Balance Sheets and presented as “Foreign currency translation adjustments” in the Condensed Consolidated Statements of Comprehensive Income (Loss).
Derivative Financial Instruments | Derivative Financial Instruments The Company has transactions and balances denominated in currencies other than the functional currency of the transacting entity. Most of these transactions carry foreign exchange risk in Germany, the United Kingdom and China. The Company enters into foreign exchange contracts to reduce its exposure to currency fluctuations. The arrangements typically mature in three months or less and they do not qualify for hedge accounting. Net gains and losses related to these contracts are recorded as a component of “Other income (expense)” in the Condensed Consolidated Statements of Operations and are as follows for the three and nine months ended June 30, 2023 and 2022 (in thousands): ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three Months Ended | ​ | Nine Months Ended
​ | ​ | June 30, | ​ | June 30,
​ |  | 2023 |  | 2022 |  | 2023 |  | 2022
Realized gains (losses) on derivatives not designated as hedging instruments | ​ | $ | 182 | ​ | $ | 848 | ​ | $ | (1,930) | ​ | $ | 1,903
​ The fair values of the forward contracts are recorded in the Condensed Consolidated Balance Sheets as “Prepaid expenses and other current assets” and “Accrued expenses and other current liabilities”. Foreign exchange contract assets and liabilities are measured and reported at fair value based on observable market inputs and classified within Level 2 of the fair value hierarchy described below due to a lack of an active market for these contracts.
Hedging Activities | 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 $1.0 billion for €915.0 million at a weighted average interest rate of 1.20%. The designated notional amount was $960.0 million and the actual interest rate was 1.28%. The 1.28% rate was in the range of the market value for that day and was the true interest rate on the notional amount. The Company designated the cross-currency swap as a hedge of net investments against one of its Euro denominated subsidiaries requiring 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 €852.0 million and received a notional amount of $960.0 million at an exchange rate of 1.13, which included realization of a gain of $29.3 million, which was recorded in “Accumulated other comprehensive income (loss)” in the Condensed Consolidated Balance Sheets. 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 $436.0 million for €400.0 million at a weighted average interest rate of 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 income (loss)” in the Condensed Consolidated Balance Sheets. Interest accrued on the cross-currency swap is recorded within “Interest income” in the Condensed Consolidated Statements of Operations. For the three and nine months ended June 30, 2023, the Company recorded a net loss of $0.2 and $70.5 million, respectively, to “Accumulated other comprehensive income (loss)” and recorded “Interest income” of $1.8 million and $7.1 million on these instruments for the three and nine months ended June 30, 2023, respectively.
Market Securities | Marketable Securities The Company invests in marketable securities that are classified as available-for-sale and records them at fair value in the Condensed Consolidated Balance Sheets. Marketable securities reported as current assets represent investments that mature within one year from the balance sheet date. Long-term marketable securities represent investments with maturity dates greater than one year from the balance sheet date. Unrealized gains and losses are excluded from earnings and reported as a separate component of “Accumulated other comprehensive income (loss)” in the Condensed Consolidated Balance Sheets until the security is sold or matures. Gains or losses realized from sales of marketable securities are computed based on the specific identification method and recognized as a component of “Other income (expense)” in the accompanying unaudited Condensed Consolidated Statements of Operations. The Company reviews the marketable securities for impairment at each reporting period to determine if any of the securities have experienced an other-than-temporary decline in fair value. The Company considers factors, such as the length of time and extent to which the market value has been less than the cost, the financial condition and near-term prospects of the issuer, the Company’s intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of its amortized cost basis. If the Company believes that an other-than-temporary decline in fair value has occurred, it writes down the investment to its fair value and recognizes the credit loss in earnings and the non-credit loss in accumulated other comprehensive income or loss.
Fair Value Measurement | Fair Value Measurement The Company measures certain financial assets and liabilities, including cash equivalents, available-for-sale securities, accounts receivable, accounts payable, contingent consideration liability and derivative instruments at fair value. The Company applies a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The following levels of inputs may be used to measure fair value:
| ● | Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that are accessible as of the reporting date. Active markets are those in which transactions for the asset and liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. The fair value hierarchy gives the highest priority to Level 1 inputs.
| ● | Level 2: Observable inputs other than prices included in Level 1, including quoted prices for similar assets or liabilities in active markets and quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
| ● | Level 3: Unobservable inputs that are significant to the fair value of the assets or liabilities and reflect an entity’s own assumptions in pricing assets or liabilities since they are supported by little or no market activity.
In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, as well as considering counterparty credit risk in its assessment of fair value. The Company measures certain assets, including the cost and equity method investments, at fair value on a nonrecurring basis when they are deemed to be other-than-temporarily impaired. The fair values of these investments are determined based on valuation techniques using the best information available, and may include quoted market prices, market comparable prices, and discounted cash flow projections. An impairment charge is recorded when the cost of the investment exceeds its fair value and this condition is determined to be other-than-temporary
Accounts Receivable and Allowance for Expected Credit Losses and Sales Returns | 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 several 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 Condensed 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 Condensed Consolidated Statements of Operations. The Company does not have any off-balance-sheet credit exposure related to its customers.
Leases | Leases The Company has operating leases for real estate and non-real estate and finance leases for non-real estate. The classification of a lease as operating or finance and the determination of the right-of-use asset (“ROU asset”) and lease liability are determined at lease inception. The ROU asset represents the Company’s right to use an underlying asset for the lease term and the lease liability represents the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, an incremental borrowing rate is used based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Lease expense is recognized on a straight-line basis over the lease term. The Company’s lease agreements may contain lease and non-lease components. Non-lease components primarily include payments for maintenance and utilities. Fixed payments for non-lease components are combined with lease payments and accounted for as a single lease component which increases the amount of the ROU asset and liability. The ROU asset for operating leases is included within “Other assets” and the ROU asset for finance leases is included within “Property, plant, and equipment, net” in the Condensed Consolidated Balance Sheets. The short-term lease liabilities for both operating leases and finance leases are included within “Accrued expenses and other current liabilities” in the Condensed Consolidated Balance Sheets. The long-term lease liabilities for operating leases and finance leases are included within “Long-term operating lease liabilities”, and “Other long-term liabilities”, respectively, in the Condensed Consolidated Balance Sheets.
Goodwill | Goodwill Goodwill represents the excess of purchase price over the fair value of net tangible and identifiable intangible assets of businesses acquired by the Company. Goodwill is tested for impairment annually or more often if impairment indicators are present at the reporting unit level. The Company elected April 1st as its annual goodwill impairment assessment date. If the existence of events or circumstances indicates that it is more likely than not that fair values of the reporting units are below their carrying values, the Company performs additional impairment tests during interim periods to evaluate goodwill for impairment. Application of the goodwill impairment test requires significant judgment based on market and operational conditions at the time of the evaluation, including management’s best estimate of future business activity and the related estimates of future cash flows from the reporting units that include the associated goodwill. These periodic evaluations could cause management to conclude that impairment factors exist, requiring an adjustment of these assets to their then current fair market values. Future business conditions and/or activity could differ materially from the projections made by management which could result in impairment charges. The goodwill impairment test is performed at the reporting unit level. A reporting unit is either an operating segment or one level below it, which is referred to as a “component”. The level at which the impairment test is performed requires an assessment of whether the operations below an operating segment constitute a self-sustaining business, in which case testing is generally performed at this level. The Company first assesses qualitative factors to determine whether the existence of events or circumstances indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the Company determines, based on this assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying value, management performs a quantitative goodwill impairment test by comparing the reporting unit’s fair value with its carrying value. An impairment loss is recognized for the amount by which the reporting unit’s carrying value exceeds its fair value, up to the total amount of goodwill allocated to the reporting unit. We determine fair values of our reporting units based on an income approach in accordance with the discounted cash flow method, (the “DCF Method”). The DCF Method is based on projected future cash flows and terminal value estimates discounted to their present values. Terminal value represents the present value an investor would pay on the valuation date for the rights to the cash flows of the business for the years subsequent to the discrete cash flow projection period. We consider the DCF Method to be the most appropriate valuation technique since it is based on management’s long-term financial projections. In addition to determining the fair value of our reporting units based on the DCF Method, we also compare the aggregate values of our net corporate assets and reporting unit fair values to our overall market capitalization and use certain market-based valuation techniques to assess the reasonableness of the reporting unit fair values determined in accordance with the DCF Method. The key inputs used in the DCF Method include revenue growth rates, gross margin percentages, selling, general and administrative expense percentages and discount rates that are at or above our weighted average cost of capital. We derive discount rates that are commensurate with the risks and uncertainties inherent in the respective reporting units and our internally developed projections of future cash flows. Application of the goodwill impairment test requires judgment based on market and operational conditions at the time of the evaluation, including management’s best estimates of the reporting unit’s future business activity and the related estimates and assumptions of future cash flows from the assets that include the associated goodwill. Different assumptions of revenue growth rates, gross margin percentages, selling, general and administrative expense percentages and the discount rate used in the DCF Method could result in different estimates of the reporting unit’s fair value as of each testing date.
Warranty Obligations | Warranty Obligations The Company establishes reserves for estimated costs of product warranties based on historical information. Product warranty reserves are recorded at the time product revenue is recognized, and retrofit accruals are recorded at the time retrofit programs are established. The Company’s warranty obligation is affected by product failure rates, utilization levels, material usage, service delivery costs incurred in correcting a product failure and supplier warranties on parts delivered to the Company.
Stock-Based Compensation | Stock-Based Compensation The fair value of restricted stock units is determined based on the number of shares granted and the closing price of the Company’s common stock quoted on the Nasdaq Stock Market on the date of grant. For awards that vest based on service conditions, the Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period. For awards that vest subject to performance conditions, the Company recognizes stock-based compensation expense ratably over the performance period if it is probable that performance condition will be met and adjusts for the percentage of shares probable of achieving the performance goals. Each quarter, management assesses the probability of achieving the performance goals. The Company makes estimates of stock award forfeitures and the number of awards expected to vest. The Company considers many factors in developing forfeiture estimates, including award types, employee classes and historical experience. Current estimates may differ from actual results and future changes in estimates.
Recently Issued and Adopted Accounting Pronouncements | Recently Issued Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope. The ASUs provide temporary optional expedients and exceptions to the GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. The provisions of the ASUs were only available until December 31, 2022, when the reference rate replacement activity was expected to be completed. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, extending the relief offered in this series of ASUs through December 31, 2024. The adoption of these ASUs is not expected to have a material impact on the Company’s consolidated financial statements. 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 the annual consolidated financial statements for fiscal 2023. In June 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. This ASU is effective for annual periods beginning after December 15, 2021. The adoption of this ASU on October 1, 2022 did not have a material impact on the Company’s consolidated financial statements.
