Automatic Data Processing, Inc. and Subsidiaries
Notes to the Consolidated Financial Statements
(Tabular dollars in millions, except per share amounts or where otherwise stated)
(Unaudited)
Note 1. Basis of Presentation
The accompanying Consolidated Financial Statements and footnotes thereto of Automatic Data Processing, Inc., its subsidiaries and variable interest entity (“ADP” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Consolidated Financial Statements and footnotes thereto are unaudited. In the opinion of the Company’s management, the Consolidated Financial Statements reflect all adjustments, which are of a normal recurring nature, that are necessary for a fair presentation of the Company’s interim financial results.
The Company has a grantor trust, which holds the majority of the funds provided by its clients pending remittance to employees of those clients, tax authorities, and other payees. The Company is the sole beneficial owner of the trust. The trust meets the criteria in Accounting Standards Codification (“ASC”) 810, “Consolidation” to be characterized as a variable interest entity (“VIE”). The Company has determined that it has a controlling financial interest in the trust because it has both (1) the power to direct the activities that most significantly impact the economic performance of the trust (including the power to make all investment decisions for the trust) and (2) the right to receive benefits that could potentially be significant to the trust (in the form of investment returns) and, therefore, consolidates the trust. Further information on these funds and the Company’s obligations to remit to its clients’ employees, tax authorities, and other payees is provided in Note 7, “Corporate Investments and Funds Held for Clients.”
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the assets, liabilities, revenue, expenses, and accumulated other comprehensive income that are reported in the Consolidated Financial Statements and footnotes thereto. Actual results may differ from those estimates. Interim financial results are not necessarily indicative of financial results for a full year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2024 (“fiscal 2024”). Certain amounts from the prior year's financial statements have been reclassified in order to conform to the current year's presentation.

Note 3. Revenue
Based upon similar operational and economic characteristics, the Company’s revenues are disaggregated by its three business pillars: Human Capital Management (“HCM”), HR Outsourcing (“HRO”), and Global Solutions (“Global”), with separate disaggregation for PEO zero-margin benefits pass-through revenues and client funds interest revenues. The Company believes these revenue categories depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors.
The following tables provide details of revenue by our business pillars, and include a reconciliation to the Company’s reportable segments:

| Three Months Ended |  | Six Months Ended

Reconciliation of disaggregated revenue to our reportable segments for the six months ended December 31, 2023:

Types of Revenues | Employer Services |  | PEO |  | Other |  | Total
HCM | $ | 3,894.0 |  |  | $ | — |  |  | $ | (4.6) |  |  | $ | 3,889.4 |
HRO, excluding PEO zero-margin benefits pass-throughs | 638.5 |  |  | 1,064.3 |  |  | (2.4) |  |  | 1,700.4 |

Total Segment Revenues | $ | 6,171.6 |  |  | $ | 3,015.7 |  |  | $ | (7.0) |  |  | $ | 9,180.3 |

Contract Balances
The timing of revenue recognition for HCM, HRO and Global is consistent with the invoicing of clients, as invoicing occurs in the period the services are provided. Therefore, the Company does not recognize a contract asset or liability resulting from the timing of revenue recognition and invoicing.
Changes in deferred revenues related to set up fees for the six months ended December 31, 2024 were as follows:

Contract Liability |
Contract liability, July 1, 2024 | $ | 491.6 |
Recognition of revenue included in beginning of year contract liability | (69.9) |
Contract liability, net of revenue recognized on contracts during the period | 60.9 |
Currency translation adjustments | (10.8) |
Contract liability, December 31, 2024 | $ | 471.8 |

Note 4. Acquisition
In October 2024, the Company acquired WorkForce Software, a premier workforce management solutions provider that specializes in supporting large, global enterprises, utilizing cash on hand. The results of WorkForce Software will be reported within the Company’s Employer Services segment. Pro forma information has not been presented because the effect of the acquisition is not material to the Company's consolidated financial results.
The following table reconciles the purchase price to the cash paid for the acquisition, net of cash acquired:

Purchase price | $ | 1,173.1 |
Less: cash acquired | (12.5) |
Cash paid for acquisition of business, net of cash acquired | $ | 1,160.6 |

The preliminary allocation of the purchase price is based upon estimates and assumptions that are subject to change within the measurement period, which is one year from the acquisition date. The primary areas of the purchase price allocation that are not yet finalized relate to the measurement of certain assets and liabilities, including identifiable intangible assets, and the finalization of net working capital items included in the purchase price allocation. Accordingly, the measurement period for such purchase price allocations will end when the information becomes available but will not exceed twelve months from the date of acquisition.
The acquisition was accounted for using the acquisition method of accounting. The Company recognized assets acquired and liabilities assumed at their fair value as of the date of acquisition, with the excess recorded to goodwill. The preliminary purchase price allocation for WorkForce Software is as follows:
9

Cash | $ | 12.5 |
Accounts receivable, net of allowance for doubtful accounts | 20.0 |
Identifiable intangible assets (1) | 417.0 |
Goodwill | 846.4 |
All other assets | 21.9 |
Total assets acquired | $ | 1,317.8 |
Deferred revenue | $ | 39.6 |
Deferred income taxes | 46.6 |
All other liabilities | 58.5 |
Total liabilities assumed | $ | 144.7 |
Total net assets acquired | $ | 1,173.1 |

(1) Intangible assets are recorded at estimated fair value, as determined by management based on available information which includes an estimated valuation by an independent third-party. The fair values assigned to identifiable intangible assets were determined through the use of the income approach, specifically the relief from royalty and the multi-period excess earnings methods. The major assumptions used in arriving at the estimated identifiable intangible asset values included management’s estimates of future cash flows, discounted at an appropriate rate of return which are based on the weighted average cost of capital for both the Company and other market participants, projected customer attrition rates, as well as applicable royalty rates for comparable assets. The useful lives for intangible assets were determined based upon the remaining useful economic lives of the intangible assets that are expected to contribute directly or indirectly to the future cash flows. The estimated fair value of intangible assets and related useful lives as included in the estimated purchase price allocation include:

| Estimated Fair Value |  | Estimated Useful Life (in years)
Technology | $ | 200.0 |  |  | 7
Customer/Partner relationships | $ | 210.0 |  |  | 8
Tradename | $ | 7.0 |  |  | 4

The goodwill recorded as a result of the WorkForce Software transaction represents future economic benefits the Company expects to achieve as a result of the acquisition, including expected synergies along with the value of the assembled workforce. None of the goodwill resulting from the acquisition is tax deductible.

Note 8. Leases
The Company records leases on the Consolidated Balance Sheets as operating lease right-of-use (“ROU”) assets, records the current portion of operating lease liabilities within accrued expenses and other current liabilities and, separately, records long-term operating lease liabilities. The difference between total ROU assets and total lease liabilities is primarily attributable to prepayments of our obligations and the recognition of various lease incentives.
The Company has entered into operating lease agreements for facilities and equipment. The Company's leases have remaining lease terms of up to approximately eleven years.

Note 10. Short-term Financing
The Company has a $4.55 billion, 364-day credit agreement that matures in June 2025 with a one year term-out option. The Company also has a $2.25 billion, five year credit facility that matures in June 2028 that contains an accordion feature under which the aggregate commitment can be increased by $500 million, subject to the availability of additional commitments. In addition, the Company also has a five year, $3.5 billion credit facility maturing in June 2029 that contains an accordion feature under which the aggregate commitment can be increased by $500 million, subject to the availability of additional commitments. The interest rate applicable to committed borrowings is tied to SOFR, the effective federal funds rate, or the prime rate depending on the notification provided by the Company to the syndicated financial institutions prior to borrowing. The Company is also required to pay facility fees on the credit agreements. The primary uses of the credit facilities are to provide liquidity to the commercial paper program and funding for general corporate purposes, if necessary. The Company had no borrowings through December 31, 2024 under the credit agreements.
The Company's U.S. short-term funding requirements related to client funds are sometimes obtained on an unsecured basis through the issuance of commercial paper, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities. This commercial paper program provides for the issuance of up to $10.3 billion in aggregate maturity value. The Company’s commercial paper program is rated A-1+ by Standard & Poor’s, Prime-1 (“P-1”) by Moody’s and F1+ by Fitch. These ratings denote the highest quality commercial paper securities. Maturities of commercial paper can range from overnight to up to 364 days. At December 31, 2024 and June 30, 2024, the Company had no commercial paper borrowing outstanding. Details of the borrowings under the commercial paper program are as follows:

| Three Months Ended |  | Six Months Ended
| December 31, |  | December 31,
| 2024 |  | 2023 |  | 2024 |  | 2023
Average daily borrowings (in billions) | $ | 4.5 |  |  | $ | 3.9 |  |  | $ | 4.7 |  |  | $ | 4.0 |
Weighted average interest rates | 4.8 | % |  | 5.4 | % |  | 5.1 | % |  | 5.3 | %
Weighted average maturity (approximately in days) | 2 days |  | 2 days |  | 2 days |  | 2 days

The Company’s U.S., Canadian and United Kingdom short-term funding requirements related to client funds obligations are sometimes obtained on a secured basis through the use of reverse repurchase agreements, which are collateralized principally by government and government agency securities, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities. These agreements generally have terms ranging from overnight to up to five business days. At December 31, 2024, the Company had no outstanding obligations related to reverse repurchase agreements. At June 30, 2024, the Company had $385.4 million of outstanding obligations related to reverse repurchase agreements which were fully paid in early July 2024. The Company has $7.3 billion available on a committed basis under the U.S. reverse repurchase agreements. Details of the reverse repurchase agreements are as follows:

| Three Months Ended |  | Six Months Ended
| December 31, |  | December 31,
| 2024 |  | 2023 |  | 2024 |  | 2023
Average outstanding balances (in billions) | $ | 3.7 |  |  | $ | 2.4 |  |  | $ | 3.7 |  |  | $ | 1.9 |
Weighted average interest rates | 4.8 | % |  | 5.4 | % |  | 5.0 | % |  | 5.4 | %

Note 11. Debt
The Company issued four series of fixed-rate notes with staggered maturities of 7 and 10 years totaling $4.0 billion (collectively the “Notes”). The Notes are senior unsecured obligations, and interest is payable in arrears, semi-annually.
During the first quarter ended September 30, 2024, the Company issued $1.0 billion of senior notes due in 2034 bearing a fixed interest rate of 4.450%. In connection with the senior notes issuance, the Company terminated several derivative contracts in place to hedge exposure in changes in benchmark interest rates for the senior notes issued with an aggregate notional amount totaling $1.0 billion (of which $400.0 million were executed during the three months ended September 30, 2024 and $600.0 million were executed on the day of issuance). Since these derivative contracts were classified as cash flow hedges, the unamortized loss of $12.5 million was deferred in accumulated other comprehensive income and will be amortized to earnings over the life of the issued Notes as the interest payments are made.
The principal amounts and associated effective interest rates of the Notes and other debt as of December 31, 2024 and June 30, 2024, are as follows:

Debt instrument |  | Effective Interest Rate |  | December 31, 2024 |  | June 30, 2024
Fixed-rate 3.375% notes due September 15, 2025 |  | 3.47% |  | $ | 1,000.0 |  |  | $ | 1,000.0 |

Note 12. Employee Benefit Plans
A. Stock-based Compensation Plans
The Company's share-based compensation consists of stock options, time-based restricted stock, time-based restricted stock units, performance-based restricted stock, and performance-based restricted stock units. The Company also offers an employee stock purchase plan for eligible employees. Beginning in September 2022, the Company discontinued granting stock options, time-based restricted stock and performance-based restricted stock. Any such future awards will be grants of time-based restricted stock units and/or performance-based restricted stock units, depending on employee eligibility. Time-based restricted stock unit awards and performance-based restricted stock unit awards granted to employees with a home country of the United States are settled in stock, and for awards granted to employees with a home country outside the United States are generally settled in cash.
The Company currently utilizes treasury stock to satisfy stock option exercises, issuances under the Company's employee stock purchase plan, and restricted stock units. From time to time, the Company may repurchase shares of its common stock under its authorized share repurchase program. The Company repurchased 0.9 million and 1.1 million shares in the three months ended December 31, 2024 and 2023, respectively, and repurchased 2.4 million and 2.1 million shares in the six months ended December 31, 2024 and 2023. The Company considers several factors in determining when to execute share repurchases, including, among other things, actual and potential acquisition activity, cash balances and cash flows, issuances due to employee benefit plan activity, and market conditions.

The following table represents pre-tax stock-based compensation expense for the three and six months ended December 31, 2024 and 2023, respectively:

| Three Months Ended |  | Six Months Ended

Net pension income | $ | (4.9) |  |  | $ | (5.8) |  |  |  |  |  |  | $ | (9.8) |  |  | $ | (11.6) |

Note 13. Income Taxes
The effective tax rate for the three months ended December 31, 2024 and 2023 was 23.6% and 23.2%, respectively. The increase in the effective tax rate is primarily due to a benefit for adjustments to prior year tax liabilities in the three months ended December 31, 2023, partially offset by a higher excess tax benefit on stock-based compensation in the three months ended December 31, 2024.
The effective tax rate for the six months ended December 31, 2024 and 2023 was 23.1% and 22.3%, respectively. The increase in the effective tax rate is primarily due to a benefit for adjustments to prior year tax liabilities, lower reserves for uncertain tax positions and a valuation allowance release in the six months ended December 31, 2023.
Note 14. Commitments and Contingencies
In May 2020, a putative class action complaint was filed against ADP, TotalSource and related defendants in the U.S. District Court, District of New Jersey. The complaint asserts violations of the Employee Retirement Income Security Act of 1974 (“ERISA”) in connection with the ADP TotalSource Retirement Savings Plan’s fiduciary administrative and investment decision-making. The complaint seeks statutory and other unspecified monetary damages, injunctive relief and attorney’s fees. The Company is unable to estimate any reasonably possible loss, or range of loss, with respect to this matter. The Company is vigorously defending against this lawsuit.
The Company is subject to various claims, litigation, and regulatory compliance matters in the normal course of business. When a loss is considered probable and reasonably estimable, the Company records a liability in the amount of its best estimate for the ultimate loss. Management currently believes that the resolution of these claims, litigation and regulatory compliance matters against us, individually or in the aggregate, will not have a material adverse impact on our consolidated results of operations, financial condition or cash flows. These matters are subject to inherent uncertainties and management's view of these matters may change in the future.
It is not the Company’s business practice to enter into off-balance sheet arrangements. In the normal course of business, the Company may enter into contracts in which it makes representations and warranties that relate to the performance of the Company’s services and products. The Company does not expect any material losses related to such representations and warranties.

FORWARD-LOOKING STATEMENTS
This document and other written or oral statements made from time to time by Automatic Data Processing, Inc., its subsidiaries and variable interest entity (“ADP” or the “Company”) may contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Statements that are not historical in nature and which may be identified by the use of words like "outlook", “expects,” “assumes,” “projects,” “anticipates,” “estimates,” “we believe,” “could,” “is designed to” and other words of similar meaning, are forward-looking statements. These statements are based on management’s expectations and assumptions and depend upon or refer to future events or conditions and are subject to risks and uncertainties that may cause actual results to differ materially from those expressed. Factors that could cause actual results to differ materially from those contemplated by the forward-looking statements or that could contribute to such difference include: ADP's success in obtaining and retaining clients, and selling additional services to clients; the pricing of products and services; the success of our new solutions; our ability to respond successfully to changes in technology, including artificial intelligence; compliance with existing or new legislation or regulations; changes in, or interpretations of, existing legislation or regulations; overall market, political and economic conditions, including interest rate and foreign currency trends and inflation; competitive conditions; our ability to maintain our current credit ratings and the impact on our funding costs and profitability; security or cyber breaches, fraudulent acts, and system interruptions and failures; employment and wage levels; availability of skilled associates; the impact of new acquisitions and divestitures; the adequacy, effectiveness and success of our business transformation initiatives and the impact of any uncertainties related to major natural disasters or catastrophic events; and supply-chain disruptions. ADP disclaims any obligation to update any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law. These risks and uncertainties, along with the risk factors discussed under “Item 1A. - Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended June 30, 2024 (“fiscal 2024”), and in other written or oral statements made from time to time by ADP, should be considered in evaluating any forward-looking statements contained herein.
NON-GAAP FINANCIAL MEASURES
In addition to our U.S. GAAP results, we use adjusted results and other non-GAAP metrics to evaluate our operating performance in the absence of certain items and for planning and forecasting of future periods. Adjusted EBIT, adjusted EBIT margin, adjusted net earnings, adjusted diluted earnings per share, adjusted effective tax rate and organic constant currency are all non-GAAP financial measures. Please refer to the accompanying financial tables in the “Non-GAAP Financial Measures” section for a discussion of why ADP believes these measures are important and for a reconciliation of non-GAAP financial measures to their comparable GAAP financial measures.

Provision for Income Taxes
The effective tax rate for the three months ended December 31, 2024 and 2023 was 23.6% and 23.2%, respectively. The increase in the effective tax rate is primarily due to a benefit for adjustments to prior year tax liabilities in the three months ended December 31, 2023, partially offset by a higher excess tax benefit on stock-based compensation in the three months ended December 31, 2024.
The effective tax rate for the six months ended December 31, 2024 and 2023 was 23.1% and 22.3%, respectively. The increase in the effective tax rate is primarily due to a benefit for adjustments to prior year tax liabilities, lower reserves for uncertain tax positions and a valuation allowance release in the six months ended December 31, 2023.
Adjusted Provision for Income Taxes
The adjusted effective tax rate for the three months ended December 31, 2024 and 2023 was 23.6% and 23.2%, respectively. The drivers of the adjusted effective tax rate are the same as the drivers of the effective tax rate discussed above.

PEO Services' revenue increased for the three and six months ended December 31, 2024, due to the increase in zero-margin benefits pass-throughs, and an increase in average worksite employees of 3% for each period, as compared to the three and six months ended December 31, 2023.
Earnings before Income Taxes
PEO Services' earnings before income taxes decreased 1% and remained flat for the three and six months ended December 31, 2024, respectively, due to increased revenues discussed above, partially offset by increases in zero-margin benefits pass-through costs, operating costs related to workers' compensation and state unemployment insurance, and selling expenses, as compared to the three and six months ended December 31, 2023.
Margin
PEO Services' margin decreased for the three and six months ended December 31, 2024 due to increases in zero-margin benefits pass-through costs, operating costs related to workers' compensation and state unemployment insurance, and selling expenses.
ADP Indemnity provides workers’ compensation and employer’s liability deductible reimbursement insurance protection for PEO Services’ worksite employees up to $1 million per occurrence. PEO Services has secured a workers’ compensation and employer’s liability insurance policy that caps the exposure for each claim at $1 million per occurrence and has also secured aggregate stop loss insurance that caps aggregate losses at a certain level in fiscal years 2012 and prior from an admitted and licensed insurance company of AIG. We utilize historical loss experience and actuarial judgment to determine the estimated claim liability, and changes in estimated ultimate incurred losses are included in the PEO segment.
Additionally, starting in fiscal year 2013, ADP Indemnity paid premiums to enter into reinsurance arrangements with ACE American Insurance Company, a wholly-owned subsidiary of Chubb Limited (“Chubb”), to cover substantially all losses incurred by the Company up to the $1 million per occurrence related to the workers' compensation and employer's liability deductible reimbursement insurance protection for PEO Services' worksite employees. Each of these reinsurance arrangements limits our overall exposure incurred up to a certain limit. The Company believes the likelihood of ultimate losses exceeding this limit is remote. ADP Indemnity recorded a pre-tax (loss)/benefit of approximately $(0.8) million and $4.1 million for the three and six months ended December 31, 2024, respectively, as compared to approximately $(1.7) million and $4.5 million for the three and six months ended December 31, 2023, respectively. The pre-tax loss for the three months ended December 31, 2024 was primarily a result of more favorable actuarial loss development in workers’ compensation reserves as compared to December 31, 2023. The pre-tax benefit for the six months ended December 31, 2024 was primarily a result of less favorable actuarial loss development in workers’ compensation reserves as compared to December 31, 2023. In July 2024, ADP Indemnity paid a premium of $276 million t o enter into a reinsurance arrangement with Chubb to cover substantially all losses incurred by ADP Indemnity for the fiscal 2025 policy year on terms substantially similar to the fiscal 2024 reinsurance policy.

Other
The primary components of “Other” are certain corporate overhead charges and expenses that have not been allocated to the reportable segments, including corporate functions, costs related to our transformation office, severance costs, non-recurring gains and losses, the elimination of intercompany transactions, and other interest income and expense.
Non-GAAP Financial Measures
In addition to our U.S. GAAP results, we use the adjusted results and other non-GAAP metrics set forth in the table below to evaluate our operating performance in the absence of certain items and for planning and forecasting of future periods:

Adjusted Financial Measure | U.S. GAAP Measures |
Adjusted EBIT | Net earnings |
Adjusted provision for income taxes | Provision for income taxes |
Adjusted net earnings | Net earnings |
Adjusted diluted earnings per share | Diluted earnings per share |
Adjusted effective tax rate | Effective tax rate |
Organic constant currency | Revenues |

We believe that the exclusion of the identified items helps us reflect the fundamentals of our underlying business model and analyze results against our expectations and against prior period, and to plan for future periods by focusing on our underlying operations. We believe that the adjusted results provide relevant and useful information for investors because it allows investors to view performance in a manner similar to the method used by management and improves their ability to understand and assess our operating performance. The nature of these exclusions is for specific items that are not fundamental to our underlying business operations. Since these adjusted financial measures and other non-GAAP metrics are not measures of performance calculated in accordance with U.S. GAAP, they should not be considered in isolation from, as a substitute for, or superior to their corresponding U.S. GAAP measures, and they may not be comparable to similarly titled measures at other companies.

(a) In Adjusted EBIT, we include the interest income earned on investments associated with our client funds extended investment strategy and interest expense on borrowings related to our client funds extended investment strategy as we believe these amounts to be fundamental to the underlying operations of our business model. The adjustments in the table above represent the interest income and interest expense that are not related to our client funds extended investment strategy and are labeled as “All other interest expense” and “All other interest income.”
(b) Represents a reserve reversal of a legal matter from fiscal 2023 previously recorded as an adjustment to EBIT.
(c) The income tax (benefit)/provision was calculated based on the annualized marginal rate in effect during the quarter of the adjustment.
(d) The Adjusted effective tax rate is calculated as our Adjusted provision for income taxes divided by the sum of our Adjusted net earnings plus our Adjusted provision for income taxes.
The following table reconciles our reported growth rates to the non-GAAP measure of organic constant currency, which excludes the impact of acquisitions, the impact of dispositions, and the impact of foreign currency. The impact of acquisitions and dispositions is calculated by excluding the current year revenues of acquisitions until the one-year anniversary of the transaction and by excluding the prior year revenues of divestitures for the one-year period preceding the transaction. The impact of foreign currency is determined by calculating the current year result using foreign exchange rates consistent with the prior year. The PEO segment is not impacted by acquisitions, dispositions or foreign currency.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCE S
At December 31, 2024, cash and cash equivalents were $2.2 billion, which were primarily invested in time deposits and money market funds.
For corporate liquidity, we expect existing cash, cash equivalents, marketable securities, cash flow from operations together with our $10.3 billion of co mmitted credit facilities and our ability to access both long-term and short-term debt financing from the capital markets will be adequate to meet our operating, investing, and financing activities such as regular quarterly dividends, share repurchases, acquisitions and capital expenditures for the foreseeable future. Our financial condition remains solid at December 31, 2024 and we have sufficient liquidity.
For client funds liquidity, we have the ability to borrow through our financing arrangements under our U.S. short-term commercial paper program and our U.S., Canadian and United Kingdom short-term reverse repurchase agreements ($7.3 billion of which is available on a committed basis in the U.S.), together with our $10.3 billion of committed credit facilities and our ability to use corporate liquidity when necessary to meet short-term funding requirements related to client funds obligations. Please see “Quantitative and Qualitative Disclosures about Market Risk” for a further discussion of the risks related to our client funds extended investment strategy. See Note 10 of our Consolidated Financial Statements for a description of our short-term financing including commercial paper.

Operating, Investing and Financing Cash Flows
Our cash flows from operating, investing, and financing activities, as reflected in the Statements of Consolidated Cash Flows for the six months ended December 31, 2024 and 2023, respectively, are summarized as follows:

|  | Six Months Ended
|  | December 31,
|  | 2024 |  | 2023 |  | $ Change
Cash provided by / (used in): |  |  |  |  |  |
Operating activities |  | $ | 1,974.7 |  |  | $ | 1,358.9 |  |  | $ | 615.8 |
Investing activities |  | (2,902.3) |  |  | (77.8) |  |  | (2,824.5) |
Financing activities |  | 7,482.5 |  |  | 3,816.1 |  |  | 3,666.4 |
Effect of exchange rate changes on cash, cash equivalents, restricted cash, and restricted cash equivalents |  | (36.7) |  |  | 10.6 |  |  | (47.3) |
Net change in cash, cash equivalents, restricted cash, and restricted cash equivalents |  | $ | 6,518.2 |  |  | $ | 5,107.8 |  |  | $ | 1,410.4 |

Net cash flows provided by operating activities increased due to favorable changes in the components of working capital and an increase in growth in our business, as compared to the six months ended December 31, 2023.
Net cash flows used in investing activities changed due to the acquisition of Workforce Software with a cash disbursement of $1,160.6 million and the timing of purchases and proceeds of corporate and client funds marketable securities of $1,664.3 million.
Net cash flows used in financing activities changed due to a net increase in the cash flow from client funds obligations of $3,668.5 million, which is due to the timing of impounds from our clients and payments to our clients' employees and other payees, along with proceeds from the issuance of debt, offset by a net decrease in cash distributed from the Internal Revenue Service as of December 31, 2024, which was refunded to our clients, repurchases of common stock, dividends paid, and proceeds related to reverse repurchase agreements.
From time to time, the Company may repurchase shares of its common stock under its authorized share repurchase program. The Company considers several factors in determining when to execute share repurchases, including, among other things, actual and potential acquisition activity, cash balances and cash flows, issuances due to employee benefit plan activity, and market conditions. We purchased approximately 2.4 million shares of our common stock at an average price per sha re o f $274.42 duri ng the six months ended December 31, 2024, as compared to purchases of 2.1 million shares at an average price per share of $238.29 during the six months ended December 31, 2023.
Capital Resources and Client Funds Obligations
We have $4.0 billion of senior unsecured notes with maturity dates in 2025, 2028, 2030 and 2034. We may from time to time revisit the long-term debt market to refinance existing debt, finance investments including acquisitions for our growth, and maintain the appropriate capital structure. However, there can be no assurance that volatility in the global capital and credit markets would not impair our ability to access these markets on terms acceptable to us, or at all. See Note 11 of our Consolidated Financial Statements for a description of our long-term financing.
Our U.S. short-term funding requirements primarily related to client funds are sometimes obtained on an unsecured basis through the issuance of commercial paper, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities. This commercial paper program provides for the issuance of up to $10.3 billion in aggregate maturity value. Our commercial paper program is rated A-1+ by St andard & Poor’s, Prime-1 (“P-1”) by Moody’s and F1+ by Fitch. These ratings denote the highest quality commercial paper securities. Maturities of commercial paper can range from overnight to up to 364 days. At December 31, 2024 and June 30, 2024, the Compa ny had no comm ercial paper borrowing outstanding. Details of the borrowings under the commercial paper program are as follows:

| Three Months Ended |  | Six Months Ended
| December 31, |  | December 31,
| 2024 |  | 2023 |  | 2024 |  | 2023
Average daily borrowings (in billions) | $ | 4.5 |  |  | $ | 3.9 |  |  | $ | 4.7 |  |  | $ | 4.0 |
Weighted average interest rates | 4.8 | % |  | 5.4 | % |  | 5.1 | % |  | 5.3 | %
Weighted average maturity (approximately in days) | 2 days |  | 2 days |  | 2 days |  | 2 days

Our U.S., Canadian, and United Kingdom short-term funding requirements related to client funds obligations are sometimes obtained on a secured basis through the use of reverse repurchase agreements, which are collateralized principally by government and government agency securities, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities. These agreements generally have terms ranging from overnight to up to five business days. We have successfully borrowed through the use of reverse repurchase agreements on an as-needed basis to meet short-term funding requirements related to client funds obligatio ns. We have $7.3 billion available to us on a committed basis under the U.S. reverse repurchase agreements. At December 31, 2024, the Company had no outstanding obligations related to reverse repurchase agreements. At June 30, 2024, the Company had $385.4 million of outstanding obligations related to reverse repurchase agreements which were fully paid in early July 2024. Details of the reverse repurchase agreements are as follows:

| Three Months Ended |  | Six Months Ended
| December 31, |  | December 31,
| 2024 |  | 2023 |  | 2024 |  | 2023
Average outstanding balances (in billions) | $ | 3.7 |  |  | $ | 2.4 |  |  | $ | 3.7 |  |  | $ | 1.9 |
Weighted average interest rates | 4.8 | % |  | 5.4 | % |  | 5.0 | % |  | 5.4 | %

We vary the maturities of our committed credit facilities to limit the refinancing risk of any one facility. We have a $4.55 billion, 364-day credit agreement that matures in June 2025 with a one year term-out option. In addition, we have a five-year $2.25 billion credit facility and a five-year $3.5 billion credit facility maturing in June 2028 and June 2029, respectively, each with an accordion feature under which the aggregate commitment can be increased by $500 million, subject to the availability of additional commitments. The primary uses of the credit facilities are to provide liquidity to the commercial paper program and funding for general corporate purposes, if necessary. We had no borrowings through December 31, 2024 under the credit facilities. We believe that we currently meet all conditions set forth in the revolving credit agreements to borrow thereunder and we are not aware of any conditions that would prevent us from borrowing part or all of the $10.3 billion available to us under the revolving credit agreements. See Note 10 of our Consolidated Financial Statements for a description of our short-term financing, including credit facilities.
Our investment portfolio does not contain any asset-backed securities with underlying collateral of sub-prime mortgages, alternative-A mortgages, sub-prime auto loans or sub-prime home equity loans, collateralized debt obligations, collateralized loan obligations, credit default swaps, derivatives, auction rate securities, structured investment vehicles or non-investment grade fixed-income securities. We own AAA-rated senior tranches of primarily fixed rate auto loan, credit card, and equipment lease receivables, secured predominantly by prime collateral. All collateral on asset-backed securities has performed as expected through December 31, 2024. In addition, we own U.S. government securities which primarily include debt directly issued by Federal Farm Credit Banks and Federal Home Loan Banks. Our client funds investment strategy is structured to allow us to average our way through an interest rate cycle by laddering the maturities of our investments out to five years (in the case of the extended portfolio) and out to ten years (in the case of the long portfolio). This investment strategy is supported by our short-term financing arrangements necessary to satisfy short-term funding requirements relating to client funds obligations. See Note 7 of our Consolidated Financial Statements for a description of our corporate investments and funds held for clients.
Capital expenditures for the six months ended December 31, 2024 were $98.2 million, as compared to $94.0 million for the six months ended December 31, 2023. We expect capital expenditures in fiscal 2025 to be between $180 million and $200 million, as compared to $211.7 million in fiscal 2024.
37

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Our overall investment portfolio is comprised of corporate investments (cash and cash equivalents, marketable securities) and client funds assets (funds that have been collected from clients but have not yet been remitted to the applicable tax authorities or client employees).
Our corporate investments are invested in cash and cash equivalents and highly liquid, investment-grade marketable securities. These assets are available for our regular quarterly dividends, share repurchases, capital expenditures and/or acquisitions, as well as other corporate operating purposes. All of our short-term and long-term fixed-income securities are classified as available-for-sale securities.
Our client funds assets are invested with safety of principal, liquidity, and diversification as the primary objectives. Consistent with those objectives, we also seek to maximize interest income and to minimize the volatility of interest income. Client funds assets are invested in highly liquid, investment-grade marketable securities, with a maximum maturity of 10 years at the time of purchase, and money market securities and other cash equivalents.
We utilize a strategy by which we extend the maturities of our investment portfolio for funds held for clients and employ short-term financing arrangements to satisfy our short-term funding requirements related to client funds obligations. Our client funds investment strategy is structured to allow us to average our way through an interest rate cycle by laddering the maturities of our investments out to five years (in the case of the extended portfolio) and out to ten years (in the case of the long portfolio). As part of our client funds investment strategy, we use the daily collection of funds from our clients to satisfy other unrelated client funds obligations, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities. In circumstances where we experience a reduction in employment levels due to a slowdown in the economy, we may make tactical decisions to sell certain securities or not reinvest maturing securities in order to reduce the size of the funds held for clients to correspond to client funds obligations. We minimize the risk of not having funds collected from a client available at the time such client’s obligation becomes due by impounding, in virtually all instances, the client’s funds in advance of the timing of payment of such client’s obligation. As a result of this practice, we have consistently maintained the required level of client funds assets to satisfy all of our obligations.
There are inherent risks and uncertainties involving our investment strategy relating to our client funds assets. Such risks include liquidity risk, including the risk associated with our ability to liquidate, if necessary, our available-for-sale securities in a timely manner in order to satisfy our client funds obligations. However, our investments are made with the safety of principal, liquidity, and diversification as the primary goals to minimize the risk of not having sufficient funds to satisfy all of our client funds obligations. We also believe we have significantly reduced the risk of not having sufficient funds to satisfy our client funds obligations by consistently maintaining access to other sources of liquidity, including our corporate cash balances, available borrowings under our $10.3 billion commercial paper program (rated A-1+ by Standard and Poor’s, P-1 by Moody’s, and F1+ by Fitch, the highest possible short-term credit ratings), and our ability to engage in reverse repurchase agreement transactions ($7.3 billion of which is available on a committed basis in the U.S.) and available borrowings under our $10.3 billion committed credit facilities. The reduced availability of financing during periods of economic turmoil, even to borrowers with the highest credit ratings, may limit our ability to access short-term debt markets to meet the liquidity needs of our business. In addition to liquidity risk, our investments are subject to interest rate risk and credit risk, as discussed below.
We have established credit quality, maturity, and exposure limits for our investments. The minimum allowed credit rating at time of purchase for Corporate, Canadian government agency and Canadian provincial bonds is BBB, for asset-backed securities is AAA, and for municipal bonds is A. The maximum maturity at time of purchase for BBB-rated securities is 5 years, and for single A rated securities, AA-rated and AAA-rated securities is 10 years. Time deposits and commercial paper must be rated A-1 and/or P-1. Money market funds must be rated AAA/Aaa-mf.

We are exposed to interest rate risk in relation to securities that mature, as the proceeds from maturing securities are reinvested. Factors that influence the earnings impact of interest rate changes include, among others, the amount of invested funds and the overall portfolio mix between short-term and long-term investments. This mix varies during the fiscal year and is impacted by daily interest rate changes. The annu alized interest rate earned on our entire p ortfolio increased from 2.7% for the six months ended December 31, 2023 to 3.2% for the six months ended December 31, 2024. A hypothetical change in both short-term interest rates (e.g., overnight interest rates or the federal funds rate) and intermediate-term interest rates of 25 basis points applied to the estimated average investment balances and any related short-term borrowings would result in approximately a $20 million impact to earnings before income taxes over the ensuing twelve-month period ending December 31, 2025. A hypothetical change in only short-term interest rates of 25 basis points applied to the estimated average short-term investment balances and any related short-term borrowings would result in approximately a $9 million impact to earnings before income taxes over the ensuing twelve-month period ending December 31, 2025.
We are exposed to credit risk in connection with our available-for-sale securities through the possible inability of the borrowers to meet the terms of the securities. We limit credit risk by investing in investment-grade securities, primarily AAA-rated and AA- rated securities, as rated by Moody’s, Standard & Poor’s, DBRS for Canadian dollar denominated securities, and Fitch for asset-backed and commercial-mortgage-backed securities. In addition, we limit amounts that can be invested in any security other than U.S. government and government agency, Canadian government, and United Kingdom government securities.
We operate and transact business in various foreign jurisdictions and are therefore exposed to market risk from changes in foreign currency exchange rates that could impact our consolidated results of operations, financial position, or cash flows. We manage our exposure to these market risks through our regular operating and financing activities and, when deemed appropriate, through the use of derivative financial instruments. We may use derivative financial instruments as risk management tools and not for trading purposes.

CRITICAL ACCOUNTING POLICIES
Our Consolidated Financial Statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of these financial statements requires management to make estimates, judgments, and assumptions that affect reported amounts of assets, liabilities, revenues, expenses, and other comprehensive income. We continually evaluate the accounting policies and estimates used to prepare the Consolidated Financial Statements. The estimates are based on historical experience and assumptions believed to be reasonable under current facts and circumstances. Actual amounts and results could differ from these estimates made by management. Refer to Note 2 of our Consolidated Financial Statements for changes to our accounting policies effective for the fiscal 2025.
NEW ACCOUNTING PRONOUNCEMENTS

Item 3. Quantitative and Qualitative Disclosures About Market Risk
The information called for by this item is provided under the caption “Quantitative and Qualitative Disclosures about Market Risk” under Item 2 – Management's Discussion and Analysis of Financial Condition and Results of Operations.
Item 4. Controls and Procedures
The Company carried out an evaluation, under the supervision and with the participation of the Company's management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company's disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (the “evaluation”). Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that the Company's disclosure controls and procedures were effective as of December 31, 2024 in ensuring that (i) information required to be disclosed by the Company in reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure and (ii) such information is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms.
There was no change in the Company's internal control over financial reporting that occurred during the three months ended December 31, 2024 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.
PART II. OTHER INFORMATION
Except as noted below, all other items are either inapplicable or would result in negative responses and, therefore, have been omitted.
Item 1. Legal Proceedings
In the normal course of business, the Company is subject to various claims and litigation. While the outcome of any litigation is inherently unpredictable, the Company believes it has valid defenses with respect to the legal matters pending against it and the Company believes that the ultimate resolution of these matters will not have a material adverse impact on its financial condition, results of operations, or cash flows.
With respect to the disclosure of administrative or judicial proceedings arising under any Federal, State, or local provisions regulating the discharge of materials into the environment or that are primarily for the purpose of protecting the environment, the Company has determined that the following threshold is reasonably designed to result in disclosure of any such proceeding that is material to its business or financial condition: any proceeding when the potential monetary sanctions exceed $1 million.
