Disclosure of Lease Cost

the operating lease expense is recorded on a straight-line basis over the lease term.

Lease costs were as follows:


	Year Ended September 30,
	2024		2023		2022
Total net lease cost(1),(2)	$	54,904	$	64,696	$	107,883

The lease cost includes immaterial amounts of lease income. The decline in net lease cost for the fiscal year 2023, compared to fiscal year 2022, is primarily attributable to completion of the move during fiscal year 2023 from leased facilities in Ra’anana Israel to the Company owned facilities, leading to a change from primarily lease costs to other expenses, including depreciation and operational costs.

(2)

Variable lease cost is immaterial.

The effective income tax rate varied from the statutory Guernsey tax rate as follows:


	Year Ended September 30,
	2024			2023			2022
Statutory Guernsey tax rate		0	%		0	%		0	%
Foreign taxes(1)		16.0			14.7			15.3
Effective income tax rate		16.0	%		14.7	%		15.3	%

As a Guernsey company subject to a corporate tax rate of zero percent, the Company’s overall effective tax rate is attributable to foreign taxes. The Company’s income before income tax expense is considered to be foreign income.

(1) Foreign taxes for the year ended Sep 30, 2024:

In fiscal year 2024, foreign taxes included a total amount of releases of gross unrecognized tax benefits of $81,556, relating primarily to settlements of tax audits, and expiration of the periods set forth in statutes of limitations in certain jurisdictions. Part of the releases amount was offset by an increase in taxes payables, and tax payments, and, as a result, a net benefit of $47,770 was included within income tax expense for fiscal year 2024.

Foreign taxes in fiscal year 2024 also included a recognition of tax benefit of $17,465 resulting from a creation of a deferred tax asset due to a change in measurement following a tax ruling in a certain jurisdiction in which the Company operates.

(1) Foreign taxes for the year ended Sep 30, 2023:

In fiscal year 2023, the Company recorded a tax benefit of $22,700 related to the release of accrued withholding taxes on unremitted earnings accumulated in Israel. The release of the accrued withholding taxes followed the Company’s funding relating to the acquisition of TEOCO’s service assurance business and the construction of its Israeli campus.

Foreign taxes in fiscal year 2023 also included a benefit of $40,644 relating to release of gross unrecognized tax benefits due to settlements of tax audits and expiration of the periods set forth in statutes of limitations in certain jurisdictions. The majority of the release was offset by tax payments and, as a result, a net benefit of $16,232 was included within income tax expense for fiscal year 2023.

Foreign taxes in fiscal year 2023 also included a recognition of tax benefit of $11,566 resulting from internal structural changes in certain jurisdictions in which the Company operates, a benefit of $9,236 due to a change in measurement of a deferred tax liability following a regulatory clarification, and a benefit of $3,142 relating to changes in tax regulations in certain jurisdictions.

As previously disclosed in the Company’s Annual Report on Form 20-F for fiscal year 2022, the Company's primary Israeli subsidiary has elected, during fiscal year 2022, to pay the reduced corporate tax on all of its “previously exempt earnings” based on a temporary order of the Israeli budget law. Following this election, payment of this tax, was made during fiscal year 2023. The impact of this election on income taxes was already reflected in fiscal year 2022.

(1) Foreign taxes for the year ended Sep 30, 2022:

In fiscal year 2022, the Company recorded a tax benefit of $37,000 related to the release of accrued withholding taxes on unremitted earnings accumulated in Israel. The release of the accrued withholding taxes followed the Company’s funding decisions relating to the construction of its new Israeli campus; such funding decisions have also taken into consideration recent changes in Israeli law and the recent application of the Preferred Technological Enterprise regime to the company’s main Israeli operating subsidiary.

Foreign taxes in fiscal year 2022 also included a benefit of $8,871 relating to changes in tax regulations in certain jurisdiction, and an expense of $3,193 for the estimated additional tax charge as a result of the gain from sale of a business (see also Note 3).

Foreign taxes in fiscal year 2022 also included a total amount of releases, net of additions related to prior years, of gross unrecognized tax benefits of $4,757 relating to effectively settled arrangements with tax authorities, changes in facts and circumstances resulting in a change in measurement of certain positions and expiration of the periods set forth in statutes of limitations in certain jurisdictions.

Foreign taxes in fiscal year 2022 also included an expense of $1,211 resulting from the creation of valuation allowances on deferred tax assets at certain of the Company’s subsidiaries, which will not likely be realized due to the Company’s projections of future taxable income.

As of September 30, 2024 and 2023, the Company indefinitely reinvest certain undistributed earnings of its foreign subsidiary and as a result has not recorded deferred tax liabilities in amounts of $101,725 and $81,700 respectively.

During fiscal year 2024 the net decrease in valuation allowances was $4,652. The valuation allowances, related to the uncertainty of realizing tax benefits primarily for tax credits, net capital and operating loss carryforwards related to certain of the Company’s subsidiaries. As of September 30, 2024, the Company had tax credits, net capital and operating loss carryforwards of $699,023 of which $202,193 have expiration dates through 2044, and the remainder do not expire.

During fiscal year 2023, the net increase in valuation allowances was $9,297. The valuation allowances, related to the uncertainty of realizing tax benefits primarily for tax credits, net capital and operating loss carryforwards related to certain of the Company’s subsidiaries. As of September 30, 2023, the Company had tax credits, net capital and operating loss carryforwards of $591,626 of which $85,347 have expiration dates through 2043, and the remainder do not expire.

The aggregate changes in the balance of the Company’s gross unrecognized tax benefits were as follows:


	Year Ended September 30,
	2024			2023			2022
Balance at beginning of fiscal year	$	196,949		$	213,031		$	195,196
Additions based on tax positions related to the current year		23,267			22,181			22,386
Additions for tax positions of prior years		15,840			18,477			8,359
Reductions for tax positions of prior years		(4,613	)		(16,096	)		(7,262	)
Settlements with tax authorities(1)		(48,622	)		(27,737	)		(1,344	)
Lapse of statute of limitations		(30,999	)		(12,907	)		(4,304	)
Balance at end of fiscal year	$	151,822		$	196,949		$	213,031

(1) The changes in the years ended September 30, 2024 and 2023 were $48,622 and $27,737 respectively, the majority of which were offset by income tax payments or changes in tax receivables and tax payables.

The total amount of unrecognized tax benefits, which includes interest and penalties, was $151,822 as of September 30, 2024, and $196,949 as of September 30, 2023, all of which would affect the effective tax rate if realized.

The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes. As of September 30, 2024, the Company had accrued $30,495 in income taxes payable for interest and penalties relating to unrecognized tax benefits. A benefit of $4,617 of interest and penalty reversals, net of interest and penalties accrual for the period, was recognized in the statements of income in fiscal year 2024. The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes. As of September 30, 2023, the Company had accrued $35,065 in income taxes payable for interest and penalties relating to unrecognized tax benefits, of which $2,253 was recognized in the statements of income in fiscal year 2023, net of interest and penalty reversals.

The Company is currently under tax audit in several jurisdictions for the tax years 2007 and onwards. Timing of the resolution of audits is highly uncertain and therefore, as of September 30, 2024, the Company cannot estimate the change in unrecognized tax benefits resulting from these audits in progress within the next 12 months.

It is reasonably possible that the amount of unrecognized tax benefits may decrease by up to $5,179 during fiscal year 2025 as a result of lapse of statutes of limitations in jurisdictions in which the Company operates.

Equity-based Compensation

Note 19 — Equity-based Compensation

Equity Incentive Plan

In January 1998, the Company adopted the 1998 Stock Option and Incentive Plan, or Equity Incentive Plan, which provides for the grant of restricted stock awards, restricted stock units and stock options and other equity-based awards to employees, officers, directors, and consultants. Since its adoption, the Equity Incentive Plan has been amended on several occasions to, among other things, increase the number of ordinary shares issuable under the Equity Incentive Plan. In February 2024, the maximum number of ordinary shares authorized to be granted under the Equity Incentive Plan was increased from 70,550 to 73,550. The amendment to the Equity Incentive Plan and became effective upon the filing of a Form S-8 Registration Statement with the U.S. Securities and Exchange Commission in February 2024. Awards granted under the Equity Incentive Plan generally vest over a period of three to four years and are generally subject to service based conditions or a combination of service and performance-based conditions and stock options have a term of ten years. Also, in accordance with the Equity Incentive Plan, options were issued at or above the market price at the time of the grant.

Employee Share Purchase Plan

On November 8, 2022, the Company’s Board of Directors adopted, subject to shareholder approval, the Amdocs Limited 2023 Employee Share Purchase Plan (the “ESPP”). The ESPP was subsequently approved by our shareholders at the annual general meeting of shareholders in January 2023. The approved number of shares that may be issued under the ESPP will not exceed in the aggregate 2,400 ordinary shares. Under its terms, the ESPP became effective upon the filing of a Form S-8 Registration Statement with the U.S. Securities and Exchange Commission. On February 13, 2023, the Company filed a registration statement on Form S-8 registering the offer and sale of 2,400 ordinary shares issuable under the ESPP. As of September 30, 2024, 548 ordinary shares have been issued since the commencement of the ESPP.

Under the ESPP, eligible employees have the right to purchase ordinary shares at the end of each purchase period based on their accumulated payroll deductions during the purchase period of a specified percentage of eligible compensation up to 10% (subject to a limitation to accrue the right to purchase ordinary shares up to twenty-five thousand dollars in any calendar year). Each purchase period lasts six months in duration, with purchases occurring in December and June. The purchase price per ordinary share will equal the lesser of 85% of the fair market value of our ordinary shares at either the beginning of the purchase period or the end of the purchase period. In fiscal year 2024 employees purchased 548 ordinary shares under the ESPP at a price of $68.95 per share, no shares have been purchased under the ESPP in fiscal year 2023, as the initial purchase was in December 2023.

	As of
	September 30, 2024			September 30, 2023
Accounts receivable — billed (net of allowance for credit losses of $32,638 and $19,801 as of September 30, 2024 and 2023, respectively)	$	665,740		$	732,979

Revenue recognized during the year ended September 30, 2024, which was included in deferred revenue (current) as of September 30, 2023 was $157,681. Revenue recognized during the year ended September 30, 2023, which was included in deferred revenue (current) as of September 30, 2022 was $245,377.

Remaining Performance Obligations from Contracts with Customer

As of September 30, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations that are unsatisfied or partially unsatisfied was approximately $5.9 billion. Remaining performance obligations typically include the remaining non-cancelable, committed and fixed portion of contracts for their entire duration and therefore it is not comparable to what the Company considers to be next 12 months backlog. Given the profile of contract terms, the majority of this amount is expected to be recognized as revenue over the next three years.

Disaggregation of Revenue

The Company considers information that is regularly reviewed by its chief operating decision makers in evaluating financial performance to disaggregate revenue. Please see Note 22 — Segment Information and Sales to Significant Customers.

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Derivative Financial Instruments

Note 7 — Derivative Financial Instruments

The Company’s risk management strategy includes the use of derivative financial instruments to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. The Company does not enter into derivative transactions for trading purposes.

The Company’s derivatives expose it to credit risks from possible non-performance by counterparties. The Company utilizes standard counterparty master netting agreements that net certain foreign currency transactions in the event of the insolvency of one of the parties to the transaction. These master netting arrangements permit the Company to net amounts due from the Company to counterparty with amounts due to the Company from the same counterparty. Although all of the Company’s recognized derivative assets and liabilities are subject to enforceable master netting arrangements, the Company has elected to present these assets and liabilities on a gross basis. Taking into account the Company’s right to net certain gains with losses, as of September 30, 2024, there is no loss due to credit risk that the Company would incur if all counterparties to the derivative financial instruments failed completely to perform, according to the terms of the contracts, based on the gross fair value of the Company's derivative contracts that are favorable to the company. The Company has limited its credit risk by entering into derivative transactions exclusively with investment-grade rated financial institutions and monitors the creditworthiness of these financial institutions on an ongoing basis.

The Company classifies cash flows from its derivative transactions as cash flows from operating activities in the consolidated statements of cash flows.

The table below presents the total volume or notional amounts of the Company’s derivative instruments as of September 30, 2024. Notional values are in U.S. dollars and are translated and calculated based on forward rates as of September 30, 2024 for forward contracts.


	Notional Value*
Foreign exchange contracts	$	1,647,952

(*) Gross notional amounts do not quantify risk or represent assets or liabilities of the Company but are used in the calculation of settlements under the contracts.

The Company records all derivative instruments on the consolidated balance sheets at fair value. For further information, please see Note 5 to the consolidated financial statements. The fair value of the open foreign exchange contracts recorded as an asset or a liability by the Company on its consolidated balance sheets as of September 30, 2024 and September 30, 2023, is as follows:

Cash Flow Hedges

In order to reduce the impact of changes in foreign currency exchange rates on its results, the Company enters into foreign currency exchange forward and option contracts to purchase and sell foreign currencies to hedge a significant portion of its foreign currency net exposure resulting from revenue and expense transactions denominated in currencies other than the U.S. dollar. The Company designates these contracts for accounting purposes as cash flow hedges. The Company currently hedges its exposure to the variability in future cash flows for a maximum period of approximately three years. A significant portion of the forward contracts outstanding as of September 30, 2024 is scheduled to mature within the next 12 months.

The effective portion of the gain or loss on the derivative instruments is initially recorded as a component of other comprehensive income (loss), a separate component of equity, and subsequently reclassified into earnings in the same line item as the related forecasted transaction and in the same period or periods during which the hedged exposure affects earnings. The cash flow hedges are evaluated for effectiveness quarterly. As the critical terms of the forward contract or option and the hedged transaction are matched at inception, the hedge effectiveness is assessed generally based on changes in the fair value for cash flow hedges, as compared to the changes in the fair value of the cash flows associated with the underlying hedged transactions. Hedge ineffectiveness, if any, is recognized immediately in interest and other expense, net.

The effect of the Company’s cash flow hedging instruments in the consolidated statements of income for the fiscal years ended September 30, 2024, 2023 and 2022, respectively, which partially offsets the foreign currency impact from the underlying exposures, is summarized as follows:


	(Losses) Gains Reclassified from Accumulated Other Comprehensive Loss (Effective Portion) Year Ended September 30,
	2024			2023			2022
Line item in consolidated statements of income:
Revenue	$	1,116		$	1,132		$	445
Cost of revenue		(15,438	)		(30,078	)		(9,194	)
Research and development		(5,020	)		(9,151	)		(3,376	)
Selling, general and administrative		(4,937	)		(9,098	)		(3,910	)
Total	$	(24,279	)	$	(47,195	)	$	(16,035	)

The activity related to the changes in net unrealized gains (losses) on cash flow hedges recorded in accumulated other comprehensive loss, net of tax, is as follows:


	Year Ended September 30,
	2024			2023			2022
Net unrealized (losses) gains on cash flow hedges, net of tax, beginning of period	$	(34,677	)	$	(46,580	)	$	13,773
Changes in fair value of cash flow hedges, net of tax		14,917			(32,655	)		(75,226	)
Reclassification of losses into earnings, net of tax		22,797			44,558			14,873
Net unrealized gains (losses) on cash flow hedges, net of tax, end of period	$	3,037		$	(34,677	)	$	(46,580	)

Net unrealized gains (losses) from cash flow hedges recognized in other comprehensive income (loss) were $15,646, $(35,654) and $(78,465), or $14,917, $(32,655) and $(75,226), net of taxes, during the fiscal years ended September 30, 2024, 2023 and 2022, respectively.

Of the net gains related to derivatives designated as cash flow hedges and recorded in accumulated other comprehensive loss as of September 30, 2024, a net loss of $749 will be reclassified into earnings during fiscal 2025 and will partially offset the foreign currency impact from the underlying exposures. The amount ultimately realized in earnings will likely differ due to future changes in foreign exchange rates.

The ineffective portion of the change in fair value of a cash flow hedge, including the time value portion excluded from effectiveness testing for the fiscal years ended September 30, 2024, 2023 and 2022, was not material.

Cash flow hedges are required to be discontinued in the event it becomes probable that the underlying forecasted hedged transaction will not occur. The Company did not discontinue cash flow hedges in material amount in fiscal year 2024, and did not discontinue any cash flow hedges during fiscal years 2023 and 2022. The Company does not anticipate any such discontinuance in the normal course of business.

Other Risk Management Derivatives

The Company also enters into foreign currency exchange forward and option contracts that are not designated as hedging instruments under hedge accounting and are used to reduce the impact of foreign currency on certain balance sheet exposures and certain revenue and expense transactions.

These instruments are generally short-term in nature, with typical maturities of less than 12 months, and are subject to fluctuations in foreign exchange rates.

The effect of the Company’s derivative instruments not designated as hedging instruments in the consolidated statements of income for the fiscal years ended September 30, 2024, 2023 and 2022, respectively, which partially offsets the foreign currency impact from the underlying exposure, is summarized as follows:

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 2 — Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, or GAAP and are denominated in U.S. dollars.

Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries, the vast majority of which are wholly-owned. All intercompany transactions and balances have been eliminated in consolidation.

In December 2017, the Company and Union Investments and Development Limited (Union) partnered through a legal entity to acquire land for the Company's campus in Ra’anana, Israel, completing the acquisition on January 2, 2018. As the Company has control over the construction and ongoing operations of the campus, the entity’s financial information is consolidated into the Company’s consolidated financial statements with the portion not owned classified as non-controlling interests. Earnings distribution began in fiscal year 2023, with negligible impact on the consolidated statement of income in fiscal years 2021 and 2022 due to negligible earnings or losses.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Reclassifications

From time to time, certain immaterial amounts in prior year financial statements may be reclassified to conform to the current year presentation.

Functional Currency

The Company manages its foreign subsidiaries as integral direct components of its operations. The Company has determined that its functional currency is the U.S. dollar. The Company periodically assesses the applicability of the U.S. dollar as the Company’s functional currency by reviewing the salient indicators as indicated in the authoritative guidance for foreign currency matters.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and interest-bearing investments with insignificant interest rate risk and maturities from acquisition date of 90 days or less.

Investments

The Company has short-term interest-bearing investments comprised of marketable securities and bank deposits. The Company classifies all of its marketable securities as available-for-sale securities and considers all of its marketable debt securities as available for use to meet the Company’s operational needs, including those with maturity dates beyond one year, and therefore classifies these securities within current assets on the consolidated balance sheets. Such marketable securities consist primarily of money market funds, corporate bonds, U.S. government treasuries and supranational and sovereign debt, which are stated at market value. The

available-for-sale investments are carried at estimated fair value with any unrealized gains and losses, net of taxes, included in accumulated other comprehensive loss in shareholders’ equity. The Company recognizes an impairment when there is a decline in the fair value of its investments below the amortized cost basis. For securities with an unrealized loss that the Company intends to sell, or it is more likely than not that the Company will be required to sell before recovery of their amortized cost basis, the entire difference between amortized cost and fair value is recognized in earnings and the available-for-sale debt security’s amortized cost basis is written down to its fair value at the reporting date. For securities that do not meet these criteria, the Company needs to assess whether the decline is as result of a credit loss, and if so, the decline is recognized in earnings, while declines in fair value related to other factors are recognized in other comprehensive income (loss). The Company uses a discounted cash flow analysis to estimate credit losses. Realized gains and losses on short-term interest-bearing investments are included in earnings and are determined based on specific identification method.

Equity Investments

The Company maintains investments, over which it does not have significant influence, in various equity securities without a readily determinable fair value, which are included within other noncurrent assets in the consolidated balance sheets. The Company reviews these investments each reporting period to determine whether an impairment or observable price change for the investment has occurred and record these changes under the consolidated statement of income.

Property and Equipment

Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful life of the asset. The estimated useful lives of property and equipment are generally as follow: computers, related equipment, and software from four to ten years, building and building improvements primarily from ten to thirty years, furniture, fixture and other from five to ten years. Leasehold improvements are amortized over the shorter of the estimated useful lives or the term of the related lease. Land is not depreciated. Property and equipment that have been fully depreciated and are no longer in use are netted against accumulated depreciation.

The Company capitalizes certain expenditures for software that is internally developed for use in the business, which is classified as computer software. Amortization of internal use software begins when the software is ready for service and continues on the straight-line method over the estimated useful life.

Cloud Implementation Costs

The Company capitalizes certain implementation costs incurred related to cloud computing arrangements for internal use that are services contracts and amortizes on a straight-line basis over the expected term of the associated hosting arrangement.

Leases

As a lessee, the majority of the Company’s lease obligation is for office real estate. The judgments used in determining its lease obligation include whether a contract is or contains a lease and the determination of the discount rate used to calculate the lease liability. The Company elected the practical expedient not to separate non-lease components from lease components and instead to account for each separate lease component and the non-lease components associated with that lease component as a single lease component for its real estate and vehicle leases.

The Company’s leases may include the option to extend or terminate before the end of the contractual term and are often non-cancelable or cancelable only by the payment of penalties. The lease assets and liabilities include these options in the lease term when it is reasonably certain that they will be exercised. In certain cases, the Company subleases excess office real estate to third-party tenants in immaterial amounts.

Lease assets and liabilities recognized at the lease commencement date are determined predominantly as the present value of the payments due over the lease term. Unless the implicit rate can be determined, the Company uses its incremental borrowing rate on that date to calculate the present value. The incremental borrowing rate approximates the rate at which the Company could borrow, on a secured basis for a similar term, an amount equal to its lease payments in a similar economic environment.

When the Company is the lessee, all leases are recognized as lease liabilities and associated lease assets on the consolidated balance sheets. Lease liabilities represent the Company’s obligation to make payments arising from the lease. Lease assets represent the Company’s right to use an underlying asset for the lease term and may also include advance payments, initial direct costs or lease incentives. Fixed and variable payments that depend upon an index or rate, such as the Consumer Price Index (CPI), are included in the recognition of lease assets and liabilities at the commencement-date rate. Other variable payments, such as common area

maintenance, property and other taxes, utilities and insurance that are based on the lessor’s cost, are recognized in the Consolidated Income Statement in the period incurred. Operating lease expense is recorded on a straight-line basis over the lease term. The Company rents out certain assets for third parties which has an immaterial impact on the Company's consolidated financial statements.

Goodwill, Intangible Assets and Long-Lived Assets

The total purchase price of business acquisitions accounted for using the purchase method is allocated first to identifiable assets and liabilities based on estimated fair values. The excess of the purchase price over the fair value of net assets of purchased businesses is recorded as goodwill.

Other definite-life intangible assets consist primarily of core technology and customer relationships. Core technology acquired by the Company is amortized over its estimated useful life on a straight-line basis.

Some of the acquired customer relationships are amortized over their estimated useful lives in proportion to the economic benefits realized. This accounting policy generally results in accelerated amortization of such customer relationships as compared to the straight-line method. All other acquired customer relationships are amortized over their estimated useful lives on a straight-line basis.

Goodwill and intangible assets deemed to have indefinite lives are subject to an annual impairment test or more frequently if impairment indicators are present. The Company's annual evaluation of impairment consists of either using a qualitative approach to determine whether it is more likely than not that the fair value of the assets is less than their respective carrying values or a quantitative impairment test, if necessary. The goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. There was no impairment of goodwill in fiscal years 2024, 2023 or 2022.

The Company tests long-lived assets, including definite life intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Impairment indicators include any significant changes in the manner of its use of the assets or the strategy of its overall business, significant negative industry or economic trends and significant decline in our share price for a sustained period. Determination of recoverability of long-lived assets is based on an estimate of the undiscounted future cash flows resulting from the use of the cash generating unit and its eventual disposition. Measurement of an impairment loss for long-lived assets, including definite life intangible assets that management expects to hold and use is based on the fair value of the cash generating unit. Long-lived assets, including definite life intangible assets, to be disposed of are reported at the lower of carrying amount or fair value less costs to sell. There was an immaterial impairment of long-lived assets in fiscal years 2024 , 2023 and 2022.

Comprehensive Income

Comprehensive income, net of related taxes where applicable, includes, in addition to net income:

(i)

net change in fair value of available-for-sale securities;

(ii)

net change in fair value of cash flow hedges; and

(iii)

net actuarial gains and losses on defined benefit plans.

Treasury Stock

The Company repurchases its ordinary shares from time to time on the open market or in other transactions and holds such shares as treasury stock. The Company presents the cost to repurchase treasury stock as a reduction of equity.

Business Combinations

In accordance with business combinations accounting, assets acquired and liabilities assumed, as well as any contingent consideration that may be part of the acquisition agreement, are recorded at their respective fair values at the date of acquisition. The Company allocates the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed, as well as to in-process research and development based on their estimated fair values. Such valuations require management to make estimates and assumptions, especially with respect to intangible assets, as a result the Company obtains the assistance of independent valuation firms. The Company completes these assessments as soon as practical after the closing dates. Any excess of the purchase price over the estimated fair values of the identifiable net assets acquired is recorded as goodwill.

For acquisitions that include contingent consideration, the fair value is estimated on the acquisition date as the present value of the expected contingent payments, determined using weighted probabilities of possible payments. The Company remeasures the fair value of the contingent consideration at each reporting period until the contingency is resolved. Except for measurement period adjustments, the changes in fair value are recognized in the consolidated statements of income. The Company considers several factors when determining that contingent consideration liabilities are part of the purchase price, such as the following: the valuation of the acquisitions is not supported solely by the initial consideration paid, and the contingent consideration payments are not affected by employment termination. Any earn-out which is not considered a contingent consideration is recognized as compensation expense over expected service period.

Although the Company believes the assumptions and estimates of fair value it has made in the past have been reasonable and appropriate, they are based in part on historical experience and information obtained from the management of the acquired companies and are inherently uncertain and subject to refinement. Critical estimates in valuing certain assets acquired and liabilities assumed include but are not limited to: future expected cash flows from license and service sales, maintenance, customer contracts and acquired developed technologies, expected costs to develop the in-process research and development into commercially viable products and estimated cash flows from the projects when completed and the acquired company’s brand awareness and discount rate. Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates or actual results. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill, if the changes are related to conditions that existed at the time of the acquisition. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments, based on events that occurred subsequent to the acquisition date, are recorded in its consolidated statements of income.

The Company estimates the fair values of its services, hardware, software license and maintenance obligations assumed. The estimated fair values of these performance obligations are determined utilizing a cost build-up approach. The cost build-up approach determines fair value by estimating the costs related to fulfilling the obligations plus a normal profit margin.

The Company may establish a valuation allowance for certain deferred tax assets and estimate the value of uncertain tax positions of a newly acquired entity. This process requires significant judgment and analysis.

Income Taxes

The Company records deferred income taxes to reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and tax purposes. Deferred taxes are computed based on enacted tax rates anticipated to be in effect when the deferred taxes are expected to be paid or realized. A valuation allowance is provided for deferred tax assets if it is more likely than not, the Company will not be able to realize their benefit. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized and adjust the valuation allowances accordingly. Factors considered in making this determination include the period of expiration of the tax asset, planned use of the tax asset, tax planning strategies and historical and projected taxable income as well as tax liabilities for the tax jurisdiction in which the tax asset is located. Valuation allowances will be subject to change in each future reporting period as a result of changes in one or more of these factors.

Deferred tax liabilities and assets are classified as noncurrent liabilities and noncurrent assets, respectively, on the consolidated balance sheets. Deferred tax liabilities also include anticipated withholding taxes due on subsidiaries’ earnings when paid as dividends to the Company.

The Company recognizes the tax benefit from an uncertain tax position only if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The tax benefits recognized in the financial statements from such a position is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes.

Significant judgment is required in evaluating the uncertain tax positions and determining the provision for income taxes. The Company adjusts these reserves in light of changing facts and circumstances, such as the closing of a tax audit, or changes in tax law. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the effect of reserve provisions and changes to reserves that are considered appropriate. Please see Note 10 to the consolidated financial statements.

The Company applies an estimated annual effective tax rate to its quarterly operating results to determine the interim provision for income tax expense. A change in judgment that impacts the measurement of a tax position taken in a prior year is recognized as a discrete item in the interim period in which the change occurs. In the event there is a significant unusual or infrequent item recognized in the quarterly operating results, the tax attributable to that item is recorded in the interim period in which it occurs. As a result, the Company’s quarterly effective tax rate may fluctuate throughout the course of a fiscal year.

Revenue Recognition

The Company recognizes revenue under the five-step methodology required under ASC 606, which requires the Company to identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations identified, and recognize revenue when (or as) each performance obligation is satisfied.

Revenue is recognized net of any revenue-based taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the Company from a customer (for example, sales, use and value added taxes).

The Company’s primary revenue categories, related performance obligations, and associated recognition patterns are as follows:

Revenue Recognition for projects — The Company usually sells its software licenses as part of an overall solution offered to a customer including significant customization, modification, implementation and integration. Those services are deemed essential to the software. As a result, revenue related to these projects is recognized over time, usually based on a percentage that incurred labor effort to date bears to total projected labor effort. Incurred effort represents work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Revenue from customization, implementation, modification and integration services is also recognized over the course of the projects. When total cost estimates for these types of arrangements exceed revenues in a fixed-price arrangement, the estimated losses are recognized immediately. Significant judgment is required when estimating total labor effort and progress to completion on these arrangements, as well as whether a loss is expected to be incurred on the project.

As a significant portion of the Company’s revenue is satisfied over time as work progresses, the annual and quarterly operating results may be affected by the size and timing of the initiation of customer projects as well as the Company’s progress in completing such projects.

Revenue Recognition for subsequent license fee — Subsequent license fee revenue is recognized when the customer has access to the license and the right to use and benefit from the license. In cases when the conditions require delivery, then delivery must have occurred for purposes of revenue recognition. Subsequent license fee is based on a customer’s subscriber level, transaction volume or other measurements when greater than the level specified in the contract for the initial license fee.

Revenue Recognition for term-based license and perpetual license — Revenue related to software solutions that do not require significant customization, implementation and modification are recognized upon delivery.

Revenue Recognition for maintenance — Maintenance revenue is recognized ratably over the term of the maintenance agreement.

Revenue Recognition for ongoing services — Revenue from ongoing support services and revenue from other ongoing services is recognized over time as services are performed, using one method of measuring performance such as time elapsed, output produced, volume of data processed or subscriber count that provides the most faithful depiction of the transfer of services.

Revenue Recognition for managed services arrangements — Managed services arrangements include management of data center operations and IT infrastructure, cloud operations, application management and ongoing support, management of end-to-end business processes, and managed transformation that includes both a transformation project as well as taking over managed services responsibility.

The revenue from managed services arrangements is recognized for each individual performance obligation according to its relevant revenue category, including, but not limited to, revenue from the management of a customer’s operations, revenue from projects and revenue from ongoing support services.

Revenue from the management of a customer’s operations pursuant to managed services arrangements is recognized over time as services are performed, using one method of measuring performance such as time elapsed, output produced, volume of data processed or subscriber count that provides the most faithful depiction of the transfer of services, pursuant to the specific contract terms of the managed services arrangements. Typically, managed services arrangements are long term in duration and their ongoing services are not subject to significant seasonality.

Revenue Recognition for third-party hardware software and services — Third-party hardware sales are typically recognized upon delivery or installation, and revenue from third-party software sales is recognized upon delivery. Maintenance revenue is recognized ratably over the term of the maintenance agreement. Revenue from third-party hardware and software sales is recorded at a gross amount for transactions in which the Company controls the third-party hardware and software prior to fulfilling the performance obligation. In specific circumstances where the Company does not meet the above criteria, revenue is recognized on a net basis. In certain arrangements, the Company may earn revenue from other third-party services which is recorded at a gross amount as it controls the services before transferring them to the customer, and recognized over time as services are performed.

Arrangements with Multiple Performance Obligations — Many of the Company’s agreements include multiple performance obligations. The Company allocates the transaction price for each contract to each performance obligation identified in the contract based on the relative standalone selling price (SSP). The Company determines SSP for the purposes of allocating the transaction price to each performance obligation by considering several external and internal factors including, but not limited to, transactions where the specific performance obligation sold separately, historical actual pricing practices and geographies in which the Company offers its services in accordance with ASC 606. The determination of SSP requires the exercise of judgment. If a specific performance obligation is sold for a broad range of amounts (that is, the selling price is highly variable) or if the Company has not yet established a price for that good or service, and the good or service has not previously been sold on a standalone basis (that is, the selling price is uncertain), the Company applies the residual approach whereby all other performance obligations within a contract are first allocated a portion of the transaction price based upon their respective SSPs with any residual amount of transaction price allocated to the remaining specific performance obligation.

Billing terms and conditions generally vary by contract category. Amounts are typically billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., monthly or quarterly) or upon achievement of contractual milestones. In cases where timing of revenue recognition significantly differs from the timing of invoicing, the Company considers whether a significant financing component exists. The Company elected to use the practical expedient in assessing the financing component in contracts where the time between cash collection and performance is less than one year.

Accounts Receivable — Billed — Billed accounts receivables include all outstanding invoices to customers, as well as amounts allowed to be billed according to contractual billing terms with customers.

Accounts Receivable — Unbilled — Unbilled accounts receivable is recorded when revenue recognition criteria is met prior to contractual billing terms being met. Unbilled accounts receivable that are expected to be billed beyond the next 12 months are considered long-term unbilled receivables and included in other noncurrent assets.

Deferred Revenue — Deferred revenue represents billings to customers for which revenue has not yet been recognized. Deferred revenue that is expected to be recognized beyond the next 12 months is considered long-term deferred revenue and included in other noncurrent liabilities.

Assets Recognized from the Costs to Obtain a Contract with a Customer — Incremental costs of obtaining a contract (e.g., sales commissions) are capitalized and amortized on a pro-rata basis over the contract period if the Company expects to recover those costs. Commissions on renewals are commensurate with the commission from the initial arrangement. Incremental costs of obtaining a contract include only those costs the Company incurs to obtain a contract that it would not have incurred if the contract had not been obtained. The Company has determined that certain sales commissions programs meet the requirements to be capitalized, which prior to the adoption of ASC 606, were previously expensed as incurred. Additionally, as a practical expedient, the Company expenses costs to obtain a contract as incurred if the amortization period would have been a year or less. The amortization of these costs is included in selling, general and administrative expenses in the Company’s consolidated statements of income.

In certain circumstances where the Company enters into a contract with a customer for the provision of managed services for a defined period of time, the Company defers certain direct costs incurred at the inception of the contract. These costs include expenses incurred in association with the origination of a contract. In addition, if the revenue for a delivered item is not recognized because it is not separable from the undelivered item, then the Company also defers the cost of the delivered item. The deferred costs are amortized on a straight-line basis over the managed services period, or over the recognition period of the undelivered item. Revenue associated with these capitalized costs is deferred and is recognized over the same period.

Cost of Revenue

Cost of revenue consists of all costs associated with providing software licenses and services to customers, third party hardware and software and identified losses on contracts. Estimated losses on projects satisfied over time as work performed are recognized in the period in which the loss is identified.

Cost of revenue also includes costs of third-party products associated with selling third-party computer hardware and software products to customers and other third-party services, when the related revenue is recorded at the gross amount. Customers purchasing third-party products and services from the Company generally do so in conjunction with the purchase of the Company’s software and services.

Research and Development

Research and development expenditures consist of costs incurred in the development of new software modules and product offerings. Research and development costs are expensed as incurred prior to the establishment of technological feasibility. Costs incurred after achieving technological feasibility and before the product is ready for customer release have been insignificant.

Equity-Based Compensation

The Company measures and recognizes the compensation expense for all equity-based payments to employees and directors based on their estimated fair values. The Company estimated the fair value of employee stock options at the date of grant using a Black-Scholes valuation model. The Company values restricted stock including performance restricted stock based on the market value of the underlying shares at the date of grant which is reduced by the present value of estimated dividends for grants of restricted stock units that do not accrue dividends. The Company values Employee Stock Purchase Plan (“ESPP”) as the discount on the market value of the underlying shares at the date of grant which is reduced by the present value of estimated dividends and using Black-Scholes valuation model. The Company recognizes compensation costs using the graded vesting attribution method that results in an accelerated recognition of compensation costs in comparison to the straight-line method. Performance restricted stock are subject to certain performance criteria; accordingly, compensation expense is recognized for such awards when it becomes probable that the related performance condition will be satisfied.

The Company uses a combination of implied volatility of the Company’s traded options and historical stock price volatility (“blended volatility”) as the expected volatility assumption required in the Black-Scholes option valuation model. As equity-based compensation expense recognized in the Company’s consolidated statements of income is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents, short-term interest-bearing investments, trade receivables and unbilled receivable. Cash and cash equivalents are maintained with several financial institutions. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions with reputable credit and therefore bear minimal credit risk. The Company seeks to mitigate its credit risks by spreading such risks across multiple financial institutions and monitoring the risk profiles of these counterparties. The Company has conservative investment policy guidelines under which it invests its excess cash primarily in highly liquid U.S. dollar-denominated securities. The Company’s revenue is generated primarily in North America. To a lesser extent, revenue is generated in Europe and the rest of the world. Most of the Company’s revenue is generated from customers who are among the largest communications and media companies in the world (or are owned by them). The Company’s business is subject to the effects of general global economic conditions and market conditions in the communications industry. The Company performs ongoing credit analyses of its customer base and generally does not require collateral.

The Company evaluates accounts receivable and unbilled receivables to determine if they ultimately will be collected. Judgments and estimates are involved in performing this evaluation, which are based on factors that may affect a customer’s ability to pay, such as past experience, credit quality of the customer, age of the receivable balance and current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect its ability to collect from customers. The allowance for doubtful accounts is for expected credit losses resulting from accounts receivable and unbilled receivables for which their collection is not reasonably probable. The allowance for doubtful accounts as of September 30, 2024 and 2023, was $32,638 and $19,801, respectively. As of September 30, 2024, the Company had one customer with accounts receivable balances of more than 10% of total accounts receivable, amounting to 25%. As of September 30, 2023, the Company had two customers with accounts receivable balances of more than 10% of total accounts receivable, aggregating to 34%, please see Note 22.

Earnings per Share

Basic earnings per share is calculated using the weighted average number of shares outstanding during the period. Diluted earnings per share is computed on the basis of the weighted average number of shares outstanding and the effect of dilutive outstanding equity-based awards using the treasury stock method. The Company includes participating securities (unvested restricted stock that contain non-forfeitable rights to dividends or dividend equivalents) in the computation of earnings per share pursuant to the two-class method, which calculates earnings per share for common shares and participating securities.

Derivatives and Hedging

The Company carries out transactions involving foreign currency exchange derivative financial instruments. The transactions are designed to hedge the Company’s exposure in currencies other than the U.S. dollar. The Company recognizes derivative instruments as either assets or liabilities and measures those instruments at fair value. If a derivative meets the definition of a cash flow hedge and is so designated, changes in the fair value of the derivative are recognized in other comprehensive income (loss) until the hedged item is recognized in earnings. The ineffective portion of a derivative designated as a cash flow hedge is recognized in earnings. If a derivative does not meet the definition of a cash flow hedge, the changes in the fair value are included in earnings.

Recent Accounting Standards

In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2024-03, "Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures", to disclose in the notes of the financial to the financial statements additional information about specific expense categories. This ASU will be effective for the Company's annual report for fiscal year 2027 and for interim period reporting beginning in fiscal year 2028, with early adoption permitted and should be applied either prospectively or retroactively. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

In December, 2023, the FASB issued ASU No. 2023-09, “Improvements to Income Tax Disclosures”, which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. This ASU will be effective for the Company's annual report for fiscal year 2026 and allows adoption on a prospective basis, with a retrospective option. This ASU will only have an impact on the Company's income tax disclosures. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), “Improvements to Reportable Segment Disclosures,” which enhances the disclosures required for operating segments in the annual and interim consolidated financial statements. This ASU will be effective for the Company's annual report for fiscal year 2025 and for interim period reporting beginning in fiscal year 2026 on a retrospective basis with early adoption permitted. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

Adoption of New Accounting Standards

In August 2021, the FASB, issued ASU No. 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.” The ASU requires companies to apply ASC 606 to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination. As of October 1, 2023, the Company prospectively adopted this ASU and there was immaterial impact on the Company’s consolidated financial statements.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 5 — Fair Value Measurements

The Company accounts for certain assets and liabilities at fair value. Fair value is the price that would be received from selling an asset or that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. The Company categorizes each of its fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety.

The three levels of inputs that may be used to measure fair value are as follows:

Level 1: Quoted prices in active markets for identical assets or liabilities;

Level 2: Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets), or other inputs that are observable (model-derived valuations in which significant inputs are observable) or can be derived principally from, or corroborated by, observable market data; and

Level 3: Unobservable inputs that are supported by little or no market activity that is significant to the fair value of the assets or liabilities.

The following tables present the Company’s assets and liabilities measured at fair value on a recurring basis as of September 30, 2024 and 2023:

Available-for-sale securities that are classified as Level 2 assets are priced using observable data that may include quoted market prices for similar instruments, market dealer quotes, market spreads, non-binding market prices that are corroborated by observable market data and other observable market information. The Company’s derivative instruments are classified as Level 2 as they represent foreign currency forward and option contracts valued primarily based on observable inputs including forward rates and yield curves. The Company did not have any transfers between Level 1 and Level 2 fair value measurements during fiscal year 2024. Level 3 liabilities relate to certain acquisition-related liabilities, which were generally valued using a Monte-Carlo simulation model and based on estimates of potential pay-out scenarios, valued during fiscal years 2024 and 2023. These liabilities were included in both accrued expenses and other current liabilities and other noncurrent liabilities as of September 30, 2024 and 2023. The increase in Level 3 liabilities was primarily attributable to new acquisition-related liabilities recorded against goodwill in connection with recent acquisitions, partially offset by payments of certain acquisition-related liabilities and changes in the fair value recorded in the consolidated statement of income in fiscal year 2024. Level 3 assets relate to equity investments. The decrease in Level 3 assets is mainly a result of changes in the fair value recorded in the consolidated statement of income.

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other current liabilities, accrued personnel costs approximate their fair value because of the relatively short maturity of these items, for the fair value of the Senior Notes, please see Note 13.

Note 3 — Acquisitions and Divestiture of a Subsidiary

Acquisitions

Entities acquired by the Company during the last three fiscal years have been consolidated into the Company’s results of operations since their respective acquisition dates. These acquisitions, individually and in the aggregate, were not material in any fiscal year. During fiscal year 2024, the Company completed two business acquisitions for an aggregate net consideration of approximately $84,007 in cash, and a potential for additional consideration which may be paid later based on achievement of certain performance metrics. The vast majority of this amount was paid for the acquisition of Astadia, which specializes in mainframe-to-cloud migration and modernization. During fiscal year 2023, the Company completed three business acquisitions for an aggregate net consideration of approximately $130,318 in cash, and a potential for additional consideration may be paid later based on achievement of certain performance metrics. Among them were the service assurance business of TEOCO and ProCom Consulting, a digital transformation SI services and business consulting company. During fiscal year 2022, the Company completed two acquisitions of technology companies, DevOps and Roam, for an aggregate net consideration of $54,091 in cash, and a potential for additional consideration may be paid later based on achievement of certain performance metrics.

Divestiture of a Subsidiary

On November 10, 2020, the Company signed an agreement for the divestiture of OpenMarket for approximately $300,000 cash with Infobip Limited, a company in which One Equity Partners is the primary institutional investor. With this transaction, the Company divested a non-strategic asset in the mobile messaging domain, remaining laser-focused on its core strategic growth initiatives. On December 31, 2020, the Company completed the divestiture. Based on the total consideration, the Company recorded pre-tax gain of $226,410 (net of immaterial transaction costs) in the Consolidated Statements of Income during the fiscal year ended September 30, 2021. In connection with this divestiture, $9,194 of net assets and $61,396 of goodwill, were disposed. During fiscal year 2022, the Company recorded additional pre-tax gain of $10,000 in the Consolidated Statements of Income as a result of achievement of certain performance metrics and received such additional consideration in cash during fiscal year 2022. The divestiture does not represent a strategic shift that will have a major effect on operations and financial results and, therefore, did not qualify for presentation as a discontinued operation, please see also Note 11.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, or GAAP and are denominated in U.S. dollars.
Consolidation	Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries, the vast majority of which are wholly-owned. All intercompany transactions and balances have been eliminated in consolidation. In December 2017, the Company and Union Investments and Development Limited (Union) partnered through a legal entity to acquire land for the Company's campus in Ra’anana, Israel, completing the acquisition on January 2, 2018. As the Company has control over the construction and ongoing operations of the campus, the entity’s financial information is consolidated into the Company’s consolidated financial statements with the portion not owned classified as non-controlling interests. Earnings distribution began in fiscal year 2023, with negligible impact on the consolidated statement of income in fiscal years 2021 and 2022 due to negligible earnings or losses.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications	Reclassifications From time to time, certain immaterial amounts in prior year financial statements may be reclassified to conform to the current year presentation.
Functional Currency	Functional Currency The Company manages its foreign subsidiaries as integral direct components of its operations. The Company has determined that its functional currency is the U.S. dollar. The Company periodically assesses the applicability of the U.S. dollar as the Company’s functional currency by reviewing the salient indicators as indicated in the authoritative guidance for foreign currency matters.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash and interest-bearing investments with insignificant interest rate risk and maturities from acquisition date of 90 days or less.
Investments	Investments The Company has short-term interest-bearing investments comprised of marketable securities and bank deposits. The Company classifies all of its marketable securities as available-for-sale securities and considers all of its marketable debt securities as available for use to meet the Company’s operational needs, including those with maturity dates beyond one year, and therefore classifies these securities within current assets on the consolidated balance sheets. Such marketable securities consist primarily of money market funds, corporate bonds, U.S. government treasuries and supranational and sovereign debt, which are stated at market value. The available-for-sale investments are carried at estimated fair value with any unrealized gains and losses, net of taxes, included in accumulated other comprehensive loss in shareholders’ equity. The Company recognizes an impairment when there is a decline in the fair value of its investments below the amortized cost basis. For securities with an unrealized loss that the Company intends to sell, or it is more likely than not that the Company will be required to sell before recovery of their amortized cost basis, the entire difference between amortized cost and fair value is recognized in earnings and the available-for-sale debt security’s amortized cost basis is written down to its fair value at the reporting date. For securities that do not meet these criteria, the Company needs to assess whether the decline is as result of a credit loss, and if so, the decline is recognized in earnings, while declines in fair value related to other factors are recognized in other comprehensive income (loss). The Company uses a discounted cash flow analysis to estimate credit losses. Realized gains and losses on short-term interest-bearing investments are included in earnings and are determined based on specific identification method
Equity Investments	Equity Investments The Company maintains investments, over which it does not have significant influence, in various equity securities without a readily determinable fair value, which are included within other noncurrent assets in the consolidated balance sheets. The Company reviews these investments each reporting period to determine whether an impairment or observable price change for the investment has occurred and record these changes under the consolidated statement of income.
Property and Equipment	Property and Equipment Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful life of the asset. The estimated useful lives of property and equipment are generally as follow: computers, related equipment, and software from four to ten years, building and building improvements primarily from ten to thirty years, furniture, fixture and other from five to ten years. Leasehold improvements are amortized over the shorter of the estimated useful lives or the term of the related lease. Land is not depreciated. Property and equipment that have been fully depreciated and are no longer in use are netted against accumulated depreciation. The Company capitalizes certain expenditures for software that is internally developed for use in the business, which is classified as computer software. Amortization of internal use software begins when the software is ready for service and continues on the straight-line method over the estimated useful life. Cloud Implementation Costs The Company capitalizes certain implementation costs incurred related to cloud computing arrangements for internal use that are services contracts and amortizes on a straight-line basis over the expected term of the associated hosting arrangement.
Leases	Leases As a lessee, the majority of the Company’s lease obligation is for office real estate. The judgments used in determining its lease obligation include whether a contract is or contains a lease and the determination of the discount rate used to calculate the lease liability. The Company elected the practical expedient not to separate non-lease components from lease components and instead to account for each separate lease component and the non-lease components associated with that lease component as a single lease component for its real estate and vehicle leases. The Company’s leases may include the option to extend or terminate before the end of the contractual term and are often non-cancelable or cancelable only by the payment of penalties. The lease assets and liabilities include these options in the lease term when it is reasonably certain that they will be exercised. In certain cases, the Company subleases excess office real estate to third-party tenants in immaterial amounts. Lease assets and liabilities recognized at the lease commencement date are determined predominantly as the present value of the payments due over the lease term. Unless the implicit rate can be determined, the Company uses its incremental borrowing rate on that date to calculate the present value. The incremental borrowing rate approximates the rate at which the Company could borrow, on a secured basis for a similar term, an amount equal to its lease payments in a similar economic environment. When the Company is the lessee, all leases are recognized as lease liabilities and associated lease assets on the consolidated balance sheets. Lease liabilities represent the Company’s obligation to make payments arising from the lease. Lease assets represent the Company’s right to use an underlying asset for the lease term and may also include advance payments, initial direct costs or lease incentives. Fixed and variable payments that depend upon an index or rate, such as the Consumer Price Index (CPI), are included in the recognition of lease assets and liabilities at the commencement-date rate. Other variable payments, such as common area maintenance, property and other taxes, utilities and insurance that are based on the lessor’s cost, are recognized in the Consolidated Income Statement in the period incurred. Operating lease expense is recorded on a straight-line basis over the lease term. The Company rents out certain assets for third parties which has an immaterial impact on the Company's consolidated financial statements.
Goodwill, Intangible Assets and Long-Lived Assets	Goodwill, Intangible Assets and Long-Lived Assets The total purchase price of business acquisitions accounted for using the purchase method is allocated first to identifiable assets and liabilities based on estimated fair values. The excess of the purchase price over the fair value of net assets of purchased businesses is recorded as goodwill. Other definite-life intangible assets consist primarily of core technology and customer relationships. Core technology acquired by the Company is amortized over its estimated useful life on a straight-line basis. Some of the acquired customer relationships are amortized over their estimated useful lives in proportion to the economic benefits realized. This accounting policy generally results in accelerated amortization of such customer relationships as compared to the straight-line method. All other acquired customer relationships are amortized over their estimated useful lives on a straight-line basis. Goodwill and intangible assets deemed to have indefinite lives are subject to an annual impairment test or more frequently if impairment indicators are present. The Company's annual evaluation of impairment consists of either using a qualitative approach to determine whether it is more likely than not that the fair value of the assets is less than their respective carrying values or a quantitative impairment test, if necessary. The goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. There was no impairment of goodwill in fiscal years 2024, 2023 or 2022. The Company tests long-lived assets, including definite life intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Impairment indicators include any significant changes in the manner of its use of the assets or the strategy of its overall business, significant negative industry or economic trends and significant decline in our share price for a sustained period. Determination of recoverability of long-lived assets is based on an estimate of the undiscounted future cash flows resulting from the use of the cash generating unit and its eventual disposition. Measurement of an impairment loss for long-lived assets, including definite life intangible assets that management expects to hold and use is based on the fair value of the cash generating unit. Long-lived assets, including definite life intangible assets, to be disposed of are reported at the lower of carrying amount or fair value less costs to sell. There was an immaterial impairment of long-lived assets in fiscal years 2024 , 2023 and 2022.
Comprehensive Income	Comprehensive Income Comprehensive income, net of related taxes where applicable, includes, in addition to net income: (i) net change in fair value of available-for-sale securities; (ii) net change in fair value of cash flow hedges; and net actuarial gains and losses on defined benefit plans
Treasury Stock	Treasury Stock The Company repurchases its ordinary shares from time to time on the open market or in other transactions and holds such shares as treasury stock. The Company presents the cost to repurchase treasury stock as a reduction of equity
Business Combinations	Business Combinations In accordance with business combinations accounting, assets acquired and liabilities assumed, as well as any contingent consideration that may be part of the acquisition agreement, are recorded at their respective fair values at the date of acquisition. The Company allocates the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed, as well as to in-process research and development based on their estimated fair values. Such valuations require management to make estimates and assumptions, especially with respect to intangible assets, as a result the Company obtains the assistance of independent valuation firms. The Company completes these assessments as soon as practical after the closing dates. Any excess of the purchase price over the estimated fair values of the identifiable net assets acquired is recorded as goodwill. For acquisitions that include contingent consideration, the fair value is estimated on the acquisition date as the present value of the expected contingent payments, determined using weighted probabilities of possible payments. The Company remeasures the fair value of the contingent consideration at each reporting period until the contingency is resolved. Except for measurement period adjustments, the changes in fair value are recognized in the consolidated statements of income. The Company considers several factors when determining that contingent consideration liabilities are part of the purchase price, such as the following: the valuation of the acquisitions is not supported solely by the initial consideration paid, and the contingent consideration payments are not affected by employment termination. Any earn-out which is not considered a contingent consideration is recognized as compensation expense over expected service period. Although the Company believes the assumptions and estimates of fair value it has made in the past have been reasonable and appropriate, they are based in part on historical experience and information obtained from the management of the acquired companies and are inherently uncertain and subject to refinement. Critical estimates in valuing certain assets acquired and liabilities assumed include but are not limited to: future expected cash flows from license and service sales, maintenance, customer contracts and acquired developed technologies, expected costs to develop the in-process research and development into commercially viable products and estimated cash flows from the projects when completed and the acquired company’s brand awareness and discount rate. Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates or actual results. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill, if the changes are related to conditions that existed at the time of the acquisition. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments, based on events that occurred subsequent to the acquisition date, are recorded in its consolidated statements of income. The Company estimates the fair values of its services, hardware, software license and maintenance obligations assumed. The estimated fair values of these performance obligations are determined utilizing a cost build-up approach. The cost build-up approach determines fair value by estimating the costs related to fulfilling the obligations plus a normal profit margin. The Company may establish a valuation allowance for certain deferred tax assets and estimate the value of uncertain tax positions of a newly acquired entity. This process requires significant judgment and analysis.
Income Taxes	Income Taxes The Company records deferred income taxes to reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and tax purposes. Deferred taxes are computed based on enacted tax rates anticipated to be in effect when the deferred taxes are expected to be paid or realized. A valuation allowance is provided for deferred tax assets if it is more likely than not, the Company will not be able to realize their benefit. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized and adjust the valuation allowances accordingly. Factors considered in making this determination include the period of expiration of the tax asset, planned use of the tax asset, tax planning strategies and historical and projected taxable income as well as tax liabilities for the tax jurisdiction in which the tax asset is located. Valuation allowances will be subject to change in each future reporting period as a result of changes in one or more of these factors. Deferred tax liabilities and assets are classified as noncurrent liabilities and noncurrent assets, respectively, on the consolidated balance sheets. Deferred tax liabilities also include anticipated withholding taxes due on subsidiaries’ earnings when paid as dividends to the Company. The Company recognizes the tax benefit from an uncertain tax position only if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The tax benefits recognized in the financial statements from such a position is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes. Significant judgment is required in evaluating the uncertain tax positions and determining the provision for income taxes. The Company adjusts these reserves in light of changing facts and circumstances, such as the closing of a tax audit, or changes in tax law. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the effect of reserve provisions and changes to reserves that are considered appropriate. Please see Note 10 to the consolidated financial statements. The Company applies an estimated annual effective tax rate to its quarterly operating results to determine the interim provision for income tax expense. A change in judgment that impacts the measurement of a tax position taken in a prior year is recognized as a discrete item in the interim period in which the change occurs. In the event there is a significant unusual or infrequent item recognized in the quarterly operating results, the tax attributable to that item is recorded in the interim period in which it occurs. As a result, the Company’s quarterly effective tax rate may fluctuate throughout the course of a fiscal year.
Revenue Recognition	Revenue Recognition The Company recognizes revenue under the five-step methodology required under ASC 606, which requires the Company to identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations identified, and recognize revenue when (or as) each performance obligation is satisfied. Revenue is recognized net of any revenue-based taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the Company from a customer (for example, sales, use and value added taxes). The Company’s primary revenue categories, related performance obligations, and associated recognition patterns are as follows: Revenue Recognition for projects — The Company usually sells its software licenses as part of an overall solution offered to a customer including significant customization, modification, implementation and integration. Those services are deemed essential to the software. As a result, revenue related to these projects is recognized over time, usually based on a percentage that incurred labor effort to date bears to total projected labor effort. Incurred effort represents work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Revenue from customization, implementation, modification and integration services is also recognized over the course of the projects. When total cost estimates for these types of arrangements exceed revenues in a fixed-price arrangement, the estimated losses are recognized immediately. Significant judgment is required when estimating total labor effort and progress to completion on these arrangements, as well as whether a loss is expected to be incurred on the project. As a significant portion of the Company’s revenue is satisfied over time as work progresses, the annual and quarterly operating results may be affected by the size and timing of the initiation of customer projects as well as the Company’s progress in completing such projects. Revenue Recognition for subsequent license fee — Subsequent license fee revenue is recognized when the customer has access to the license and the right to use and benefit from the license. In cases when the conditions require delivery, then delivery must have occurred for purposes of revenue recognition. Subsequent license fee is based on a customer’s subscriber level, transaction volume or other measurements when greater than the level specified in the contract for the initial license fee. Revenue Recognition for term-based license and perpetual license — Revenue related to software solutions that do not require significant customization, implementation and modification are recognized upon delivery. Revenue Recognition for maintenance — Maintenance revenue is recognized ratably over the term of the maintenance agreement. Revenue Recognition for ongoing services — Revenue from ongoing support services and revenue from other ongoing services is recognized over time as services are performed, using one method of measuring performance such as time elapsed, output produced, volume of data processed or subscriber count that provides the most faithful depiction of the transfer of services. Revenue Recognition for managed services arrangements — Managed services arrangements include management of data center operations and IT infrastructure, cloud operations, application management and ongoing support, management of end-to-end business processes, and managed transformation that includes both a transformation project as well as taking over managed services responsibility. The revenue from managed services arrangements is recognized for each individual performance obligation according to its relevant revenue category, including, but not limited to, revenue from the management of a customer’s operations, revenue from projects and revenue from ongoing support services. Revenue from the management of a customer’s operations pursuant to managed services arrangements is recognized over time as services are performed, using one method of measuring performance such as time elapsed, output produced, volume of data processed or subscriber count that provides the most faithful depiction of the transfer of services, pursuant to the specific contract terms of the managed services arrangements. Typically, managed services arrangements are long term in duration and their ongoing services are not subject to significant seasonality. Revenue Recognition for third-party hardware software and services — Third-party hardware sales are typically recognized upon delivery or installation, and revenue from third-party software sales is recognized upon delivery. Maintenance revenue is recognized ratably over the term of the maintenance agreement. Revenue from third-party hardware and software sales is recorded at a gross amount for transactions in which the Company controls the third-party hardware and software prior to fulfilling the performance obligation. In specific circumstances where the Company does not meet the above criteria, revenue is recognized on a net basis. In certain arrangements, the Company may earn revenue from other third-party services which is recorded at a gross amount as it controls the services before transferring them to the customer, and recognized over time as services are performed. Arrangements with Multiple Performance Obligations — Many of the Company’s agreements include multiple performance obligations. The Company allocates the transaction price for each contract to each performance obligation identified in the contract based on the relative standalone selling price (SSP). The Company determines SSP for the purposes of allocating the transaction price to each performance obligation by considering several external and internal factors including, but not limited to, transactions where the specific performance obligation sold separately, historical actual pricing practices and geographies in which the Company offers its services in accordance with ASC 606. The determination of SSP requires the exercise of judgment. If a specific performance obligation is sold for a broad range of amounts (that is, the selling price is highly variable) or if the Company has not yet established a price for that good or service, and the good or service has not previously been sold on a standalone basis (that is, the selling price is uncertain), the Company applies the residual approach whereby all other performance obligations within a contract are first allocated a portion of the transaction price based upon their respective SSPs with any residual amount of transaction price allocated to the remaining specific performance obligation. Billing terms and conditions generally vary by contract category. Amounts are typically billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., monthly or quarterly) or upon achievement of contractual milestones. In cases where timing of revenue recognition significantly differs from the timing of invoicing, the Company considers whether a significant financing component exists. The Company elected to use the practical expedient in assessing the financing component in contracts where the time between cash collection and performance is less than one year. Accounts Receivable — Billed — Billed accounts receivables include all outstanding invoices to customers, as well as amounts allowed to be billed according to contractual billing terms with customers. Accounts Receivable — Unbilled — Unbilled accounts receivable is recorded when revenue recognition criteria is met prior to contractual billing terms being met. Unbilled accounts receivable that are expected to be billed beyond the next 12 months are considered long-term unbilled receivables and included in other noncurrent assets. Deferred Revenue — Deferred revenue represents billings to customers for which revenue has not yet been recognized. Deferred revenue that is expected to be recognized beyond the next 12 months is considered long-term deferred revenue and included in other noncurrent liabilities. Assets Recognized from the Costs to Obtain a Contract with a Customer — Incremental costs of obtaining a contract (e.g., sales commissions) are capitalized and amortized on a pro-rata basis over the contract period if the Company expects to recover those costs. Commissions on renewals are commensurate with the commission from the initial arrangement. Incremental costs of obtaining a contract include only those costs the Company incurs to obtain a contract that it would not have incurred if the contract had not been obtained. The Company has determined that certain sales commissions programs meet the requirements to be capitalized, which prior to the adoption of ASC 606, were previously expensed as incurred. Additionally, as a practical expedient, the Company expenses costs to obtain a contract as incurred if the amortization period would have been a year or less. The amortization of these costs is included in selling, general and administrative expenses in the Company’s consolidated statements of income. In certain circumstances where the Company enters into a contract with a customer for the provision of managed services for a defined period of time, the Company defers certain direct costs incurred at the inception of the contract. These costs include expenses incurred in association with the origination of a contract. In addition, if the revenue for a delivered item is not recognized because it is not separable from the undelivered item, then the Company also defers the cost of the delivered item. The deferred costs are amortized on a straight-line basis over the managed services period, or over the recognition period of the undelivered item. Revenue associated with these capitalized costs is deferred and is recognized over the same period.
Cost of Revenue	Cost of Revenue Cost of revenue consists of all costs associated with providing software licenses and services to customers, third party hardware and software and identified losses on contracts. Estimated losses on projects satisfied over time as work performed are recognized in the period in which the loss is identified. Cost of revenue also includes costs of third-party products associated with selling third-party computer hardware and software products to customers and other third-party services, when the related revenue is recorded at the gross amount. Customers purchasing third-party products and services from the Company generally do so in conjunction with the purchase of the Company’s software and services.
Research and Development	Research and Development Research and development expenditures consist of costs incurred in the development of new software modules and product offerings. Research and development costs are expensed as incurred prior to the establishment of technological feasibility. Costs incurred after achieving technological feasibility and before the product is ready for customer release have been insignificant.
Equity-Based Compensation	Equity-Based Compensation The Company measures and recognizes the compensation expense for all equity-based payments to employees and directors based on their estimated fair values. The Company estimated the fair value of employee stock options at the date of grant using a Black-Scholes valuation model. The Company values restricted stock including performance restricted stock based on the market value of the underlying shares at the date of grant which is reduced by the present value of estimated dividends for grants of restricted stock units that do not accrue dividends. The Company values Employee Stock Purchase Plan (“ESPP”) as the discount on the market value of the underlying shares at the date of grant which is reduced by the present value of estimated dividends and using Black-Scholes valuation model. The Company recognizes compensation costs using the graded vesting attribution method that results in an accelerated recognition of compensation costs in comparison to the straight-line method. Performance restricted stock are subject to certain performance criteria; accordingly, compensation expense is recognized for such awards when it becomes probable that the related performance condition will be satisfied. The Company uses a combination of implied volatility of the Company’s traded options and historical stock price volatility (“blended volatility”) as the expected volatility assumption required in the Black-Scholes option valuation model. As equity-based compensation expense recognized in the Company’s consolidated statements of income is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents, short-term interest-bearing investments, trade receivables and unbilled receivable. Cash and cash equivalents are maintained with several financial institutions. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions with reputable credit and therefore bear minimal credit risk. The Company seeks to mitigate its credit risks by spreading such risks across multiple financial institutions and monitoring the risk profiles of these counterparties. The Company has conservative investment policy guidelines under which it invests its excess cash primarily in highly liquid U.S. dollar-denominated securities. The Company’s revenue is generated primarily in North America. To a lesser extent, revenue is generated in Europe and the rest of the world. Most of the Company’s revenue is generated from customers who are among the largest communications and media companies in the world (or are owned by them). The Company’s business is subject to the effects of general global economic conditions and market conditions in the communications industry. The Company performs ongoing credit analyses of its customer base and generally does not require collateral. The Company evaluates accounts receivable and unbilled receivables to determine if they ultimately will be collected. Judgments and estimates are involved in performing this evaluation, which are based on factors that may affect a customer’s ability to pay, such as past experience, credit quality of the customer, age of the receivable balance and current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect its ability to collect from customers. The allowance for doubtful accounts is for expected credit losses resulting from accounts receivable and unbilled receivables for which their collection is not reasonably probable. The allowance for doubtful accounts as of September 30, 2024 and 2023, was $32,638 and $19,801, respectively. As of September 30, 2024, the Company had one customer with accounts receivable balances of more than 10% of total accounts receivable, amounting to 25%. As of September 30, 2023, the Company had two customers with accounts receivable balances of more than 10% of total accounts receivable, aggregating to 34%, please see Note 22.
Earnings per Share	Earnings per Share Basic earnings per share is calculated using the weighted average number of shares outstanding during the period. Diluted earnings per share is computed on the basis of the weighted average number of shares outstanding and the effect of dilutive outstanding equity-based awards using the treasury stock method. The Company includes participating securities (unvested restricted stock that contain non-forfeitable rights to dividends or dividend equivalents) in the computation of earnings per share pursuant to the two-class method, which calculates earnings per share for common shares and participating securities.
Derivatives and Hedging	Derivatives and Hedging The Company carries out transactions involving foreign currency exchange derivative financial instruments. The transactions are designed to hedge the Company’s exposure in currencies other than the U.S. dollar. The Company recognizes derivative instruments as either assets or liabilities and measures those instruments at fair value. If a derivative meets the definition of a cash flow hedge and is so designated, changes in the fair value of the derivative are recognized in other comprehensive income (loss) until the hedged item is recognized in earnings. The ineffective portion of a derivative designated as a cash flow hedge is recognized in earnings. If a derivative does not meet the definition of a cash flow hedge, the changes in the fair value are included in earnings.
Recent Accounting Standards	Recent Accounting Standards In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2024-03, "Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures", to disclose in the notes of the financial to the financial statements additional information about specific expense categories. This ASU will be effective for the Company's annual report for fiscal year 2027 and for interim period reporting beginning in fiscal year 2028, with early adoption permitted and should be applied either prospectively or retroactively. The Company is currently evaluating the impact of the adoption on its consolidated financial statements. In December, 2023, the FASB issued ASU No. 2023-09, “Improvements to Income Tax Disclosures”, which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. This ASU will be effective for the Company's annual report for fiscal year 2026 and allows adoption on a prospective basis, with a retrospective option. This ASU will only have an impact on the Company's income tax disclosures. The Company is currently evaluating the impact of the adoption on its consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), “Improvements to Reportable Segment Disclosures,” which enhances the disclosures required for operating segments in the annual and interim consolidated financial statements. This ASU will be effective for the Company's annual report for fiscal year 2025 and for interim period reporting beginning in fiscal year 2026 on a retrospective basis with early adoption permitted. The Company is currently evaluating the impact of the adoption on its consolidated financial statements. Adoption of New Accounting Standards In August 2021, the FASB, issued ASU No. 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.” The ASU requires companies to apply ASC 606 to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination. As of October 1, 2023, the Company prospectively adopted this ASU and there was immaterial impact on the Company’s consolidated financial statements.

Debt Disclosure [Abstract]

Financing Arrangements

Note 13 — Financing Arrangements

In December 2011, the Company entered into an unsecured $500,000 five-year revolving credit facility with a syndicate of banks (the “Revolving Credit Facility”). In December 2014, December 2017, March 2021 and July 2024, the Revolving Credit Facility was amended and restated to, among other things, extend the maturity date of the facility to December 2019, December 2022 March 2026 and July 2029, respectively. As of September 30, 2024, the Company was in compliance with the financial covenants and had no outstanding borrowings under the Revolving Credit Facility.

In June 2020, the Company issued an aggregate principal amount of $650,000 in Senior Notes that will mature in June 2030 and bear interest at a fixed rate of 2.538 percent per annum (the “Senior Notes”). The interest is payable semi-annually in June and December of each year, commencing in December 2020. The Company incurred issuance costs of $6,121 in relation with the Senior Notes which are being amortized to interest expenses over the term of the Senior Notes using the effective interest rate. The Senior Notes are senior unsecured obligations of the Company and rank equally in right of payment with all existing and future senior indebtedness of the Company, including any indebtedness the Company may incur from time to time under the Revolving Credit Facility.

The total interest expense recognized in connection with the Senior Notes for the years ended September 30, 2024, 2023 and 2022 were $17,128, 17,066 and 17,052, respectively. The accrued interest on the Senior Notes is included in accrued expenses and other current liabilities and were $4,831 and 4,795, respectively, as of September 30, 2024 and 2023. As of September 30, 2024, the noncurrent outstanding principal portion was $650,000.

The total estimated fair value of the Senior Notes as of September 30, 2024 and 2023 was $579,774 and $521,164, respectively. The fair value was determined based on the closing trading price of Senior Notes as of September 30, 2024 and 2023, and is deemed a Level 2 liability within the fair value measurement framework.

As of September 30, 2024, the Company had additional uncommitted lines of credit available for general corporate and other specific purposes and had outstanding letters of credit and bank guarantees from various banks totaling $80,880. These were supported by a combination of the uncommitted lines of credit that the Company maintains with various banks.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.
