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 6, “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, 2019 (“fiscal 2019”).

Revision of Previously Reported Financial Information

The Company has historically classified certain fees collected from worksite employers for certain benefits within PEO revenues, and the associated costs of these benefits have historically been classified within operating expenses as PEO zero-margin benefits pass-through costs in the Company's Statements of Consolidated Earnings. During the quarter ended September 30, 2019, management determined that the Company does not retain risk and is acting as the agent, rather than as the primary obligor, for a portion of the fees collected for worksite employee benefits and the worksite employer is primarily responsible for fulfilling certain aspects of the service and has discretion in establishing price. Accordingly, the accompanying Statements of Consolidated Earnings for the three months ended September 30, 2018 has been revised to correct the amounts previously reported on a gross basis to a net basis by reducing PEO revenues and operating expenses for associated costs of an equal amount, as follows:

	Three Months Ended
	September 30, 2018
	As reported		Revision		As revised
PEO revenues	$	986.1	(12.9	)	$	973.2
TOTAL REVENUES	3,323.2		(12.9	)	3,310.3
Operating expenses	1,709.9		(12.9	)	1,697.0
Total Expenses	2,690.3		(12.9	)	2,677.4
EARNINGS BEFORE INCOME TAXES	646.8		—		646.8
Provision for income taxes	141.4		—		141.4
NET EARNINGS	$	505.4	—		$	505.4

7

In addition, the revised amounts for the fiscal year ended June 30, 2019 are as follows:

	Twelve Months Ended
	June 30, 2019
	As reported		Revision		As revised
PEO revenues	$	4,237.5	(65.0	)	$	4,172.5
TOTAL REVENUES	14,175.2		(65.0	)	14,110.2
Operating expenses	7,145.9		(65.0	)	7,080.9
Total Expenses	11,280.7		(65.0	)	11,215.7
EARNINGS BEFORE INCOME TAXES	3,005.6		—		3,005.6
Provision for income taxes	712.8		—		712.8
NET EARNINGS	$	2,292.8	—		$	2,292.8

The correction of these previously reported amounts had no impact on the Company's earnings before income taxes, net earnings, consolidated financial condition or cash flows. In addition, corresponding revisions have been made elsewhere in the Company's consolidated footnote disclosures, where applicable, including its Interim Financial Data by Segment disclosure.

Note 2.  New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Effective July 1, 2019, the Company adopted accounting standard update (“ASU”) 2016-02, “Leases (ASC 842)” under the optional transition method. As a result, the Company recorded on the Consolidated Balance Sheets total operating lease right-of-use (“ROU”) assets of $573.3 million and total operating lease liabilities of $522.6 million, as of the adoption date. The adoption did not have an impact on our Statements of Consolidated Earnings or Statements of Consolidated Cash Flows. Refer to Note 7 for further details.

Recently Issued Accounting Pronouncements

The following table summarizes recent ASU's issued by the Financial Accounting Standards Board (“FASB”) which have been assessed:

Standard	Description	Effective Date	Effect on Financial Statements or Other Significant Matters
ASU 2018-14 Compensation-Retirement Benefits-Defined Benefit Plans	This update modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year, and (b) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for post-retirement health care benefits. Additional disclosures include descriptions of significant gains and losses affecting the benefit obligation for the period. The amendments in ASU 2018-14 would need to be applied on a retrospective basis.	July 1, 2021 (Fiscal 2022)	The adoption of this guidance will modify disclosures but will not have an impact on the Company's consolidated results of operations, financial condition, or cash flows.

8

Standard	Description	Effective Date	Effect on Financial Statements or Other Significant Matters
ASU 2018-13 Fair Value Measurement	This update modifies the disclosure requirements on fair value measurements. Certain disclosures in ASU 2018-13 would need to be applied on a retrospective basis and others on a prospective basis.	July 1, 2020 (Fiscal 2021)	The adoption of this guidance will modify disclosures but will not have an impact on the Company's consolidated results of operations, financial condition, or cash flows.
ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	This update introduces the current expected credit loss (CECL) model, which will require an entity to measure credit losses for certain financial instruments and financial assets, including trade receivables. Under this update, on initial recognition and at each reporting period, an entity will be required to recognize an allowance that reflects the entity’s current estimate of credit losses expected to be incurred over the life of the financial instrument. In addition, this update modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination.	July 1, 2020 (Fiscal 2021)	The adoption of this guidance will not have a material impact on its consolidated results of operations, financial condition, or cash flows.

Note 3.  Revenue

Based upon similar operational and economic characteristics, the Company’s revenues are disaggregated by its three strategic pillars: HCM (“HCM”), HR Outsourcing (“HRO”), and Global (“Global”) Solutions with separate disaggregation for PEO zero-margin benefits pass-through revenues and client fund 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.

HCM provides a suite of product offerings that assist employers of all types and sizes in all stages of the employment cycle, from recruitment to retirement. Global is generally consistent with the types of services provided within HCM but represents geographies outside of the United States and includes our multinational offerings. HCM and Global revenues are primarily attributable to fees for providing solutions for payroll, benefits, talent, retirement services and HR processing and fees charged to implement the Company's solutions for clients.

HRO provides a comprehensive human resources outsourcing solution, including offering benefits, providing workers’ compensation insurance, and administering state unemployment insurance, among other human resources functions. This revenue is primarily driven by the PEO. Amounts collected from PEO worksite employers include payroll, fees for benefits, and an administrative fee that also includes payroll taxes, fees for workers’ compensation and state unemployment taxes. The payroll and payroll taxes collected from the worksite employers are presented in revenue net, as the Company does not retain risk and acts as an agent with respect to this aspect of the PEO arrangement. With respect to the payroll and payroll taxes, the worksite employer is primarily responsible for providing the service and has discretion in establishing wages. The fees collected from the worksite employers for benefits (i.e., PEO benefits pass-throughs), workers’ compensation and state unemployment taxes are presented in revenues and the associated costs of benefits, workers’ compensation and state unemployment taxes are included in operating expenses, as the Company acts as a principal with respect to this aspect of the arrangement. With respect to these fees, the Company is primarily responsible for fulfilling the service and has discretion in establishing price. The Company has further disaggregated HRO to separate out its PEO zero-margin benefits pass-through revenues.

The Company recognizes client fund interest revenues on collected but not yet remitted funds held for clients in revenues as earned, as the collection, holding and remittance of these funds are critical components of providing these services.

The following tables provide details of revenue by our strategic pillars with disaggregation for PEO zero-margin benefits pass-throughs and client fund interest, and includes a reconciliation to the Company’s reportable segments:

	Three Months Ended

Types of Revenues	Employer Services		PEO		Other			Total
HCM	$	1,521.8	$	—	$	(1.5	)	$	1,520.3
HRO, excluding PEO zero-margin benefits pass-throughs	226.1		332.7		(1.3		)	557.5

Total Segment Revenues	$	2,338.2	$	974.9	$	(2.8	)	$	3,310.3

Contract Balances

The timing of revenue recognition for our HCM, HRO and Global Solutions 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 revenue related to set up fees for the three months ended September 30, 2019 were as follows:

Contract Liability
Contract liability, July 1, 2019	$	563.4
Recognition of revenue included in beginning of year contract liability	(45.4		)
Contract liability, net of revenue recognized on contracts during the period	31.2
Currency adjustments	(4.5		)
Contract liability, September 30, 2019	$	544.7

Options to purchase 0.7 million and 0.3 million shares of common stock for the three months ended September 30, 2019 and 2018, respectively, were excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

Long-term marketable securities (a)	576.0		261.4
Total corporate investments	$	5,525.0	$	2,221.1

(a) - Long-term marketable securities are included within Other assets on the Consolidated Balance Sheets.

Funds held for clients represent assets that, based upon the Company's intent, are restricted for use solely for the purposes of satisfying the obligations to remit funds relating to the Company’s payroll and payroll tax filing services, which are classified as client funds obligations on our Consolidated Balance Sheets.

Funds held for clients have been invested in the following categories:

	September 30,		June 30,
	2019		2019
Funds held for clients:
Restricted cash and cash equivalents held to satisfy client funds obligations	$	868.3	$	4,847.0
Restricted short-term marketable securities held to satisfy client funds obligations	1,168.6		5,013.9
Restricted long-term marketable securities held to satisfy client funds obligations	19,356.3		19,573.3
Total funds held for clients	$	21,393.2	$	29,434.2

Client funds obligations represent the Company's contractual obligations to remit funds to satisfy clients' payroll, tax, and other payee payment obligations and are recorded on the Consolidated Balance Sheets at the time that the Company impounds funds from clients. The client funds obligations represent liabilities that will be repaid within one year of the balance sheet date. The Company has reported client funds obligations as a current liability on the Consolidated Balance Sheets totaling $21,011.4 million and $29,144.5 million at September 30, 2019 and June 30, 2019, respectively. The Company has classified funds held for clients as a current asset since these funds are held solely for the purpose of satisfying the client funds obligations. Of the Company’s funds held for clients at September 30, 2019 and June 30, 2019, $18,898.2 million and $26,648.0 million, respectively, are held in the grantor trust. The liabilities held within the trust are intercompany liabilities to other Company subsidiaries and are eliminated in consolidation.

The Company has reported the cash flows related to the purchases of corporate and client funds marketable securities and related to the proceeds from the sales and maturities of corporate and client funds marketable securities on a gross basis in the investing section of the Statements of Consolidated Cash Flows. The Company has reported the cash and cash equivalents related to client funds investments with original maturities of ninety days or less, within the beginning and ending balances of

14

cash, cash equivalents, restricted cash, and restricted cash equivalents. These amounts have been reconciled to the Consolidated Balance Sheets on the Statements of Consolidated Cash Flows. The Company has reported the cash flows related to the cash received from and paid on behalf of clients on a net basis within net increase in client funds obligations in the financing activities section of the Statements of Consolidated Cash Flows.

Approximately 79% of the available-for-sale securities held a AAA or AA rating at September 30, 2019, as rated by Moody's, Standard & Poor's, DBRS for Canadian dollar-denominated securities, and Fitch for asset-backed and commercial mortgage-backed securities.  All available-for-sale securities were rated as investment grade at September 30, 2019.

Expected maturities of available-for-sale securities at September 30, 2019 are as follows:

One year or less	$	4,713.6
One year to two years	6,040.5
Two years to three years	4,743.3
Three years to four years	3,726.7

Total available-for-sale securities	$	24,646.0

Note 7.  Leases

During the first quarter of the fiscal year ending June 30, 2020 ("fiscal 2020"), the Company adopted ASC 842 using the optional transition method under which financial results reported in periods prior were not adjusted and continue to be reported in accordance with historic accounting under ASC 840 - Leases.

The Company elected the following practical expedients permitted under the lease standard:

• The Company did not reassess prior conclusions about lease identification, lease classification or initial direct costs, and did not use hindsight for leases existing at adoption date.

• The Company did not record leases with an initial term of 12 months or less on the consolidated balance sheet but continues to expense them on a straight-line basis over the lease term.

• The Company elected to combine lease and non-lease components for our facilities leases only. Non-lease components consist primarily of maintenance services.

The Company records leases on the consolidated balance sheets as operating lease 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 Company has entered into operating lease agreements for facilities and equipment. The Company's leases have remaining lease terms of up to approximately ten years. Operating lease ROU assets and operating lease liabilities are recognized at the lease commencement date based on the present value of the lease payments over the lease term. The lease liabilities are measured by discounting future lease payments at the Company’s collateralized incremental borrowing rate for financing instruments of a similar term, unless the implicit rate is readily determinable. ROU assets also include adjustments related to prepaid or deferred lease payments and lease incentives. As of September 30, 2019, total operating lease ROU assets were $504.0 million, current and long-term operating lease liabilities were approximately $103.3 million and $355.4 million, respectively. The difference between total ROU assets and total lease liabilities are primarily attributable to pre-payments of our obligations and the recognition of various lease incentives.

The components of operating lease expense were as follows for the three months ended September 30, 2019:

Operating lease cost	$	44.2
Short-term lease cost	2.7
Variable lease cost	1.3
Total operating lease cost	$	48.2

15

Information related to our operating lease ROU assets and operating lease liabilities was as follows:

	September 30, 2019
Cash paid for operating lease liabilities	$	40.2
Operating lease ROU assets obtained in exchange for new operating lease liabilities	$	6.7
Weighted-average remaining lease term (in years)	6
Weighted-average discount rate	2.4		%

As of September 30, 2019, maturities of operating lease liabilities are as follows:

Nine months ending June 30, 2020	$	87.0
Twelve months ending June 30, 2021	97.1
Twelve months ending June 30, 2022	80.8
Twelve months ending June 30, 2023	68.2
Twelve months ending June 30, 2024	47.6

	(2,583.9		)	(2,546.4		)
Intangible assets, net	$	1,078.9		$	1,071.5

Other intangibles consist primarily of purchased rights, trademarks and trade names (acquired directly or through acquisitions).  All intangible assets have finite lives and, as such, are subject to amortization.  The weighted average remaining useful life of the intangible assets is 6 years (6 years for software and software licenses, 6 years for customer contracts and lists, and 5 years for other intangibles).  Amortization of intangible assets was $69.4 million and $53.4 million for the three months ended September 30, 2019 and 2018, respectively.

16

Estimated future amortization expenses of the Company's existing intangible assets are as follows:

	Amount
Nine months ending June 30, 2020	$	209.7
Twelve months ending June 30, 2021	$	223.0

Twelve months ending June 30, 2024	$	108.8
Twelve months ending June 30, 2025	$	61.4

Note 9. Short-term Financing

The Company has a $3.8 billion, 364-day credit agreement that matures in June 2020 with a one year term-out option.  The Company also has a $2.75 billion five year credit facility that matures in June 2024 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 has a five year $3.75 billion credit facility maturing in June 2023 that also 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 LIBOR, 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 September 30, 2019 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 and Prime-1 by Moody’s.  These ratings denote the highest quality commercial paper securities. Maturities of commercial paper can range from overnight to up to 364 days. At September 30, 2019, the Company had $3,536.7 million of commercial paper outstanding, which was repaid in early October 2019. At June 30, 2019, the Company had no commercial paper borrowing outstanding. Details of the borrowings under the commercial paper program are as follows:

	Three Months Ended
	September 30,
	2019			2018
Average daily borrowings (in billions)	$	4.0		$	3.7
Weighted average interest rates	2.3		%	2.0		%
Weighted average maturity (approximately in 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 September 30, 2019 and June 30, 2019, the Company had $428.6 million and $262.0 million, respectively, of outstanding obligations related to the reverse repurchase agreements. All outstanding reverse repurchase obligations matured and were fully paid in early October 2019 and early July 2019, respectively. Details of the reverse repurchase agreements are as follows:

	Three Months Ended
	September 30,
	2019			2018
Average outstanding balances	$	426.6		$	495.1
Weighted average interest rates	2.0		%	1.7		%

Note 10. Debt

The Company has fixed-rate notes with 5-year and 10-year maturities for an aggregate principal amount of $2.0 billion (collectively the “Notes”). The Notes are senior unsecured obligations, and interest is payable in arrears, semi-annually.

The principal amounts and associated effective interest rates of the Notes and other debt as of September 30, 2019 and June 30, 2019, are as follows:

Debt instrument	Effective Interest Rate	September 30, 2019			June 30, 2019
Fixed-rate 2.25% notes due September 15, 2020	2.37%	$	1,000.0		$	1,000.0
Fixed-rate 3.375% notes due September 15, 2025	3.47%	1,000.0			1,000.0
Other		9.2			10.9
		2,009.2			2,010.9
Less: current portion		(1,001.3		)	(2.5		)
Less: unamortized discount and debt issuance costs		(4.5		)	(6.2		)
Total long-term debt		$	1,003.4		$	2,002.2

The effective interest rates for the Notes include the interest on the Notes and amortization of the discount and debt issuance costs.

As of September 30, 2019, the fair value of the Notes, based on Level 2 inputs, was $2,074.1 million. For a description of the fair value hierarchy and the Company's fair value methodologies, including the use of an independent third-party service, see Note 1 “Summary of Significant Accounting Policies” in the Company's Annual Report on Form 10-K for fiscal 2019.

Note 11. Employee Benefit Plans

A.  Stock-based Compensation Plans. Stock-based compensation consists of the following:

• Stock Options.  Stock options are granted to employees at exercise prices equal to the fair market value of the Company's common stock on the dates of grant. Stock options generally vest ratably over 4 years and have a term of 10 years. Compensation expense is measured based on the fair value of the stock option on the grant date and recognized on a straight-line basis over the vesting period. Stock options are forfeited if the employee ceases to be employed by the Company prior to vesting.

• Restricted Stock.

• Time-Based Restricted Stock and Time-Based Restricted Stock Units. Time-based restricted stock and time-based restricted stock units granted September 1, 2018 and after generally vest ratably over 3 years. Time-based restricted stock and time-based restricted stock units granted prior to September 1, 2018 are generally subject to a vesting period of 2 years. Awards are forfeited if the employee ceases to be employed by the Company prior to vesting.

Time-based restricted stock cannot be transferred during the vesting period. Compensation expense relating to the issuance of time-based restricted stock is measured based on the fair value of the award on the grant date and recognized on a straight-line basis over the vesting period. Dividends are paid on shares awarded under the time-based restricted stock program.

Time-based restricted stock units are settled in cash and cannot be transferred during the vesting period. Compensation expense relating to the issuance of time-based restricted stock units is recorded over the vesting period and is initially based on the fair value of the award on the grant date and is subsequently remeasured at each reporting date during the vesting period based on the change in the ADP stock price. No dividend equivalents are paid on units awarded under the time-based restricted stock unit program.

• Performance-Based Restricted Stock and Performance-Based Restricted Stock Units. Performance-based restricted stock and performance-based restricted stock units generally vest over a one to three year performance period and a subsequent service period of up to 38 months. Under these programs, the Company communicates “target awards” at the beginning of the performance period with possible payouts at the end of

18

the performance period ranging from 0% to 150% of the “target awards.” Awards are generally forfeited if the employee ceases to be employed by the Company prior to vesting.

Performance-based restricted stock cannot be transferred during the vesting period. Compensation expense relating to the issuance of performance-based restricted stock is recognized over the vesting period based on the fair value of the award on the grant date with subsequent adjustments to the number of shares awarded during the performance period based on probable and actual performance against targets. After the performance period, if the performance targets are achieved, employees are eligible to receive dividends during the remaining vesting period on shares awarded under the performance-based restricted stock program.

Performance-based restricted stock units cannot be transferred and are settled in either cash or stock, depending on the employee's home country. Compensation expense relating to the issuance of performance-based restricted stock units settled in cash is recognized over the vesting period initially based on the fair value of the award on the grant date with subsequent adjustments to the number of units awarded during the performance period based on probable and actual performance against targets. In addition, compensation expense is remeasured at each reporting period during the vesting period based on the change in the ADP stock price. Compensation expense relating to the issuance of performance-based restricted stock units settled in stock is recorded over the vesting period based on the fair value of the award on the grant date with subsequent adjustments to the number of units awarded based on the probable and actual performance against targets. Dividend equivalents are paid on awards under the performance-based restricted stock unit program.

• Employee Stock Purchase Plan. The Company offers an employee stock purchase plan that allows eligible employees to purchase shares of common stock at a price equal to 95% of the market value for the Company's common stock on the last day of the offering period. This plan has been deemed non-compensatory and, therefore, no compensation expense has been recorded.

The Company currently utilizes treasury stock to satisfy stock option exercises, issuances under the Company's employee stock purchase plan, and restricted stock awards. From time to time, the Company may repurchase shares of its common stock under its authorized share repurchase programs. The Company repurchased 1.9 million and 1.6 million shares in the three months ended September 30, 2019 and 2018, respectively. 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 months ended September 30, 2019 and 2018, respectively:

	Three Months Ended
	September 30,
	2019		2018
Operating expenses	$	4.0	$	5.4
Selling, general and administrative expenses	28.3		28.0

B.  Pension Plans

The components of net pension expense were as follows:

	Three Months Ended
	September 30,
	2019			2018
Service cost – benefits earned during the period	$	14.9		$	14.9
Interest cost on projected benefits	15.4			19.7
Expected return on plan assets	(29.5		)	(32.9		)
Net amortization and deferral	1.6			0.1
Settlement charges and special termination benefits	(5.1		)	15.3
Net pension expense	$	(2.7	)	$	17.1

In fiscal 2018, the Company offered a voluntary early retirement program (“VERP”) to certain eligible U.S.-based associates aged 55 or above with at least 10 years of service. During the three months ended September 30, 2018, the Company recorded $15.3 million of non-cash settlement charges and special termination benefits.

Note 12. Income Taxes

The effective tax rate for the three months ended September 30, 2019 and 2018 was 21.2% and 21.9%, respectively. The decrease in the effective tax rate is due to an increase in tax incentives related to our software development activities and a decrease in reserves for uncertain tax positions in the three months ended September 30, 2019. This was partially offset by a decrease in the excess tax benefit on stock-based compensation in the three months ended September 30, 2019 and the income tax benefit related to the Tax Cuts and Job Act in the three months ended September 30, 2018.

Note 13. Commitments and Contingencies

In June 2018, a potential class action complaint was filed against ADP in the Circuit Court of Cook County, Illinois. The complaint asserts that ADP violated the Illinois Biometric Privacy Act, was negligent and unjustly enriched itself in connection with its collection, use and storage of biometric data of employees of its clients who are residents of Illinois in connection with certain services provided by ADP to clients in Illinois. The complaint seeks statutory and other unspecified monetary damages, injunctive relief and attorney’s fees. In addition, similar potential class action complaints have been filed in Illinois state courts against ADP and/or certain of its clients with respect to the collection, use and storage of biometric data of the employees of these clients. All of these claims are still in their earliest stages and the Company is unable to estimate any reasonably possible loss, or range of loss, with respect to these matters. The Company intends to vigorously defend against these lawsuits.

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.

Note 16. Interim Financial Data by Segment

Based upon similar economic and operational characteristics, the Company’s strategic business units have been aggregated into the following two reportable segments: Employer Services and PEO Services. The primary components of the “Other” segment 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, non-recurring gains and losses, the elimination of intercompany transactions, and interest expense. Certain revenues and expenses are charged to the reportable segments at a standard rate for management reasons. Other costs are recorded based on management responsibility. Beginning in the first quarter of fiscal 2020, the Company made changes to the allocation methodology for certain corporate allocations, in both the current period and the prior period in the table below, which did not materially affect reportable segment results. In addition, the segment results in the table below reflect the impact of the revision to PEO revenues for comparability. Refer to Note 1 to our consolidated financial statements for more information on this revision.

RESULTS AND ANALYSIS OF CONSOLIDATED OPERATIONS

Total Revenues

For the three months ended September 30th:

Quarter over quarter growth:	á	6%
Organic constant currency:	á	6%

Our revenue growth includes nearly one percentage point of unfavorability from foreign currency offset by benefits from acquisitions. Revenues for the three months ended September 30, 2019 increased due to new business started from New Business Bookings and continued strong retention. Refer to “Analysis of Reportable Segments” for additional discussion of the increases in revenue for both of our reportable segments, Employer Services and Professional Employer Organization (“PEO”) Services.

Total revenues for the three months ended September 30, 2019 include interest on funds held for clients of $133.9 million, as compared to $118.5 million for the three months ended September 30, 2018. The increase in the consolidated interest earned on funds held for clients resulted from an increase in the average interest rate earned to 2.3% for the three months ended September 30, 2019, as compared to 2.1% for the three months ended September 30, 2018, coupled with an increase in our average client funds balance of 6.8% to $23.7 billion for the three months ended September 30, 2019, as compared to the three months ended September 30, 2018.

Total Expenses

	Three Months Ended				% Change
	September 30,
	2019		2018		As Reported
Costs of revenues:
Operating expenses	$	1,787.7	$	1,697.0	5	%
Systems development and programming costs	168.2		158.0		6	%
Depreciation and amortization	88.9		72.6		22	%
Total costs of revenues	2,044.8		1,927.6		6	%

Interest expense	39.9		35.9		n/m
Total expenses	$	2,811.2	$	2,677.4	5	%

n/m - not meaningful

Our total expenses increased due to an increase in PEO Services zero-margin benefits pass-through costs, increased costs to service our client base in support of our growing revenue and increased selling and marketing expenses. The increase was partially offset by net charges related to our transformation initiatives in the three months ended September 30, 2018, operating efficiencies as a result of our continued successful execution on transformation initiatives, and the impact of foreign currency in the three months ended September 30, 2019.

27

Operating expenses increased as our PEO Services zero-margin benefits pass-through costs increased to $699.1 million from $640.5 million for the three months ended September 30, 2019 and 2018, respectively. Additionally, operating expenses increased due to increased costs to service our client base in support of our growing revenue partially offset by operating efficiencies as a result of our continued successful execution on our transformation initiatives and the impact of foreign currency.

Systems development and programming costs increased due to increased investments and costs to develop, support, and maintain our products partially offset by capitalization of costs related to our strategic projects, including our next gen platforms, and reduced costs as a result of our transformation initiatives. Depreciation and amortization expense increased related to the amortization of our internally developed software and acquisitions of intangibles.

Selling, general and administrative expenses increased due to increased selling and marketing expenses as a result of investments in our sales force and our brand. The increase was partially offset by broad-based efficiencies as a result of our transformation initiatives during the three months ended September 30, 2019 and net charges related to our transformation initiatives in the three months ended September 30, 2018.

Non-service components of pension expense, net	(18.1		)	1.6			19.7
Other income, net	$	(54.6	)	$	(13.9	)	$	40.7

Other income, net, increased $40.7 million for the three months ended September 30, 2019, as compared to the three months ended September 30, 2018. The increase was due to the non-service components of pension expense, net during the three months ended September 30, 2019. Additionally, in fiscal 2018, we wrote down $12.1 million of internally developed software which was determined to have no future use due to redundant software identified as part of an acquisition.

Earnings before Income Taxes (“EBIT”)

For the three months ended September 30th:

Quarter over quarter growth: á 14% á 160bps

Earnings before income taxes increased due to the increases in revenues partially offset by increases in expenses discussed above.

28

Overall margin increased as a result of our continued successful execution of our broad-based transformation initiatives as well as operating efficiencies and improvements in our systems infrastructure spend. In addition, the increase was aided by an increase in interest earned on funds held for clients and a decrease in charges of $33.1 million related to our transformation initiatives during the three months ended September 30, 2019. These were partially offset by incremental pressure from growth in our zero-margin benefits pass-throughs and increased selling and marketing expenses.

Adjusted EBIT

For the three months ended September 30th:

Quarter over quarter growth: á 8% á 60bps

Adjusted EBIT excludes charges related to our transformation initiatives in the respective periods for the three months ended September 30, 2019 and 2018, reflecting a decrease in charges of $33.1 million during the three months ended September 30, 2019. Adjusted EBIT increased due to the increases in revenues offset by the increases in expenses discussed above. Our adjusted EBIT margin reflects changes described above in our EBIT margin.

Provision for Income Taxes

The effective tax rate for the three months ended September 30, 2019 and 2018 was 21.2% and 21.9%, respectively. The decrease in the effective tax rate is due to an increase in tax incentives related to our software development activities and a decrease in reserves for uncertain tax positions in the three months ended September 30, 2019. This was partially offset by a decrease in the excess tax benefit on stock-based compensation in the three months ended September 30, 2019 and the income tax benefit related to the Tax Cuts and Job Act (“Act”) in the three months ended September 30, 2018.

Adjusted Provision for Income Taxes

The adjusted effective tax rate excludes the impact of charges related to our transformation initiatives and the income tax benefit related to the Act in the respective periods for the three months ended September 30, 2019 and 2018. The adjusted effective tax rate for the three months ended September 30, 2019 and 2018 was 21.2% and 22.2%, respectively. The drivers of the decrease in the adjusted effective tax rate are the same as the effective tax rate, with the exception of the income tax benefit related to the Act, discussed above.

29

Net Earnings and Diluted EPS

For the three months ended September 30th:

Quarter over quarter growth: á 15% á 17%

Net earnings reflects the changes described above in our earnings before income taxes and our effective tax rate.

Diluted EPS increased as a result of an increase in net earnings and the impact of fewer shares outstanding, resulting from the repurchase of approximately 1.9 million shares during the three months ended September 30, 2019 and 1.6 million shares for the three months ended September 30, 2018, partially offset by the issuances of shares under our employee benefit plans.

Adjusted Net Earnings and Adjusted Diluted EPS

For the three months ended September 30th:

Quarter over quarter growth: á 10% á 12%

Adjusted net earnings reflects the changes described above in our adjusted EBIT and our adjusted effective tax rate.

Adjusted diluted EPS reflects the changes described above in our adjusted net earnings and shares outstanding.

Employer Services

Revenues

Revenues increased due to new business started from New Business Bookings and continued strong retention. Our revenue growth includes about one percentage point of unfavorability from foreign currency partially offset by benefits from acquisitions. Our revenues also increased due to the interest earned on funds held for clients, which benefited from improvement in the average yield earned on our client fund investments and growth in average client funds balances, and an increase in the number of employees on our clients’ payrolls as our pays per control increased 2.4% for the three months ended September 30, 2019 as compared to the three months ended September 30, 2018. Our pays per control metric measures the number of employees on our clients' payrolls as measured on a same-store-sales basis utilizing a representative subset of payrolls ranging from small to large businesses that are reflective of a broad range of U.S. geographic regions.

Earnings before Income Taxes

Employer Services’ earnings before income taxes increased 6% due to increased revenues discussed above offset by increased expenses due to increased costs to service our client base in support of our growing revenue and increased selling and marketing expenses as a result of investments in our sales force and our brand. These increases in expenses were partially offset by operating efficiencies as a result of our transformation initiatives and the impact from foreign currency.

31

Quarter over quarter growth: á 50bps

Employer Services' overall margin increased as a result of the continued successful execution of our broad-based transformation initiatives, as well as operating efficiencies and improvements in our systems infrastructure spend, and was aided by an increase in interest earned on funds held for clients. This increase was partially offset by increased selling and marketing expenses.

PEO Services

Revenues

	PEO Revenues
	Three Months Ended				Change

	2019		2018		$		%
PEO Services' revenues	$	1,056.9	$	974.9	$	82.0	8	%

PEO Services' revenues excluding zero-margin benefits pass-throughs	$	357.8	$	334.4	$	23.4	7	%

PEO Services' revenues increased 8% due to a 7% increase in the average number of Worksite Employees for the three months ended September 30, 2019 driven by an increase in the number of new PEO Services clients and growth of our existing clients. PEO Services' revenue excluding zero-margin benefits pass-throughs increased 7% and includes pressure from lower workers compensation and State Unemployment Insurance (“SUI”) costs and related pricing.

Earnings before Income Taxes

PEO Services' earnings before income taxes increased 3% due to the increased revenues discussed above offset by an increase in expenses of $77.3 million. The increase in expenses was related to an increase in zero-margin benefits pass-through costs of $58.6 million described above and a decrease of $5.3 million in pre-tax benefit related to ADP Indemnity reserve adjustments, which drove about 60 basis points of pressure, in the three months ended September 30, 2019, as compared to the three months ended September 30, 2018.

Quarter over quarter growth: â 70bps

PEO Services' overall margin decreased due to a decrease of $5.3 million in pre-tax benefit from ADP Indemnity in the three months ended September 30, 2019, as compared to the three months ended September 30, 2018.

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 has a $1 million per occurrence retention and, in fiscal years 2012 and prior, aggregate stop loss insurance that covers any aggregate losses within the $1 million retention that collectively exceed a certain level, from an admitted and licensed insurance company of AIG. The Company has obtained approximately $242 million of irrevocable standby letters of credit in favor of licensed insurance companies of AIG to secure TotalSource workers’ compensation obligations if ADP were to fail to reimburse AIG for workers’ compensation payments. The Company had no drawdowns during the three months ended September 30, 2019 and September 30, 2018, respectively, under the letters of credit. 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. ADP Indemnity recorded a pre-tax benefit of approximately $3.4 million for the three months ended September 30, 2019, compared to $8.7 million for the three months ended September 30, 2018. For the fiscal years 2013 to 2019, ADP Indemnity paid premiums to enter into reinsurance arrangements with ACE American Insurance Company, a wholly-owned subsidiary of Chubb Limited, to cover substantially all losses incurred by ADP Indemnity during these policy years. Each of these reinsurance arrangements limits our overall exposure incurred up to a certain limit. We believe the likelihood of ultimate losses exceeding this limit is remote. For the three months ended September 30, 2019, ADP Indemnity paid a premium of $215.0 million to enter into a reinsurance arrangement with Chubb Limited to cover substantially all losses incurred by ADP Indemnity for the fiscal 2020 policy year on terms substantially similar to the fiscal 2019 reinsurance policy.

Other

The primary components of the “Other” segment 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, non-recurring gains and losses, the elimination of intercompany transactions, and interest 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) 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 is not related to our client funds extended investment strategy and are labeled as “All other interest expense” and “All other interest income.”

(b) The transformation initiatives for the three months ended September 30, 2019 include net reversals of charges related to our Voluntary Early Retirement Program (“VERP”) of $5.8 million, and a gain on sale of assets related to our Service Alignment Initiative of $1.9 million, offset by charges of $7.1 million related to other transformation initiatives. Unlike other severance charges which are not included as an adjustment to get to adjusted results, these specific charges relate to actions that are part of our broad-based, company-wide transformation initiative.

(c) The tax provision (benefit) on transformation initiatives was calculated based on the annualized marginal rate in effect during the quarter of the adjustment.

(d) There was no impact from the Tax Cuts and Jobs Act in the three months ended September 30, 2019.

(e) 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 RESOURCES

For corporate liquidity, we expect existing cash, cash equivalents, short-term marketable securities, long-term marketable securities, and cash flow from operations, together with our $10.3 billion of committed 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 our regular quarterly dividends, share repurchases, and capital expenditures.

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 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 of our client funds extended investment strategy. See Note 9 of our Consolidated Financial Statements for a description of our short-term financing including commercial paper.

As of September 30, 2019, cash and cash equivalents were $1.4 billion, which were primarily invested in time deposits and money market funds.

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 three months ended September 30, 2019 and 2018, respectively, are summarized as follows:

	Three Months Ended
	September 30,
	2019			2018			$ Change
Cash provided by / (used in):
Operating activities	$	432.8		$	149.2		$	283.6
Investing activities	122.2			(452.7		)	574.9

Net change in cash, cash equivalents, restricted cash, and restricted cash equivalents	$	(4,524.0	)	$	(2,133.8	)	$	(2,390.2	)

35

Net cash flows provided by operating activities for the three months ended September 30, 2019 and September 30, 2018 include cash payments for reinsurance agreements of $215.0 million and $218.0 million, respectively, which represent the policy premium for the entire fiscal year. The increase in operating cash provided is due to a net favorable change in the components of working capital within operating activities, as compared to the three months ended September 30, 2018.

Net cash flows from investing activities changed due to the timing of proceeds offset by purchases of corporate and client funds marketable securities of $459.8 million, lower payments made related to acquisitions and proceeds from sale of assets, partially offset by payments made related to acquisitions of intangibles and capital expenditures in the three months ended September 30, 2019.

Net cash flows from financing activities changed due to a net decrease in client fund obligations of $6,351.8 million, which is due to the timing of impounds from our clients and payments to our clients' employees and other payees, and more cash returned to shareholders via dividends and share repurchases, partially offset by an increase in net proceeds from commercial paper borrowings for the three months ended September 30, 2019.

We purchased 1.9 million shares of our common stock at an average price per share of $164.80 during the three months ended September 30, 2019, as compared to purchases of 1.6 million shares at an average price per share of $138.59 during the three months ended September 30, 2018. From time to time, the Company may repurchase shares of its common stock under its authorized share repurchase programs. 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.

Capital Resources and Client Funds Obligations

We have $2.0 billion of senior unsecured notes with maturity dates in 2020 and 2025. 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 10 of our Consolidated Financial Statements for a description of our long-term financing.

Our 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. Our commercial paper program is rated A-1+ by Standard & Poor’s and Prime-1 (“P-1”) by Moody’s. These ratings denote the highest quality commercial paper securities. Maturities of commercial paper can range from overnight to up to 364 days. At September 30, 2019, the Company had  $3,536.7 million of commercial paper outstanding, which was repaid in early October 2019. At June 30, 2019, the Company had no commercial paper borrowing outstanding. Details of the borrowings under the commercial paper program are as follows:

	Three Months Ended
	September 30,
	2019			2018
Average daily borrowings (in billions)	$	4.0		$	3.7
Weighted average interest rates	2.3		%	2.0		%
Weighted average maturity (approximately in 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 obligations. At September 30, 2019 and June 30, 2019, there were $428.6 million and $262.0 million, respectively, of outstanding obligations related to reverse repurchase agreements. All outstanding reverse repurchase obligations matured and were fully paid in early October 2019 and early July 2019, respectively. Details of the reverse repurchase agreements are as follows:

	Three Months Ended
	September 30,
	2019			2018
Average outstanding balances	$	426.6		$	495.1
Weighted average interest rates	2.0		%	1.7		%

We vary the maturities of our committed credit facilities to limit the refinancing risk of any one facility. We have a $3.8 billion, 364-day credit agreement that matures in June 2020 with a one year term-out option. In addition, we have a five-year $2.75 billion credit facility and a five-year $3.75 billion credit facility maturing in June 2024 and June 2023, 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 September 30, 2019 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 9 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 fixed rate credit card, auto loan, equipment lease and rate reduction receivables, secured predominantly by prime collateral. All collateral on asset-backed securities is performing as expected. In addition, we own senior debt directly issued by Federal Home Loan Banks and Federal Farm Credit 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 6 of our Consolidated Financial Statements for a description of our corporate investments and funds held for clients.

Capital expenditures for the three months ended September 30, 2019 were $52.2 million, as compared to $42.1 million for the three months ended September 30, 2018. Capital expenditures for fiscal 2020 are expected to be about $175 million, as compared to $163 million in fiscal 2019.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our overall investment portfolio is comprised of corporate investments (cash and cash equivalents, short-term and long-term 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. 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

37

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 and P-1 by Moody’s, the highest possible credit ratings), and our ability to engage in reverse repurchase transactions 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, for single A rated securities is 7 years, and for 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.

Total available-for-sale securities at fair value	$	24,646.0	$	24,859.1

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 annualized interest rates earned on our entire portfolio increased from 2.1% for the three months ended September 30, 2018 to 2.2% for the three months ended September 30, 2019. A hypothetical change in both

38

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 $13 million impact to earnings before income taxes over the ensuing twelve-month period ending September 30, 2020. 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 $4 million impact to earnings before income taxes over the ensuing twelve-month period ending September 30, 2020.

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 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. Approximately 79% of our available-for-sale securities held a AAA or AA rating at September 30, 2019. 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. We had no derivative financial instruments outstanding at September 30, 2019.

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 year ended June 30, 2020 (“fiscal 2020”).

Short-Term Financing [Abstract]

Short-term Financing

Short-term Financing

The Company has a $3.8 billion, 364-day credit agreement that matures in June 2020 with a one year term-out option.  The Company also has a $2.75 billion five year credit facility that matures in June 2024 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 has a five year $3.75 billion credit facility maturing in June 2023 that also 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 LIBOR, 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 September 30, 2019 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 and Prime-1 by Moody’s.  These ratings denote the highest quality commercial paper securities. Maturities of commercial paper can range from overnight to up to 364 days. At September 30, 2019, the Company had $3,536.7 million of commercial paper outstanding, which was repaid in early October 2019. At June 30, 2019, the Company had no commercial paper borrowing outstanding. Details of the borrowings under the commercial paper program are as follows:

	Three Months Ended
	September 30,
	2019			2018
Average daily borrowings (in billions)	$	4.0		$	3.7
Weighted average interest rates	2.3		%	2.0		%
Weighted average maturity (approximately in 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 September 30, 2019 and June 30, 2019, the Company had $428.6 million and $262.0 million, respectively, of outstanding obligations related to the reverse repurchase agreements. All outstanding reverse repurchase obligations matured and were fully paid in early October 2019 and early July 2019, respectively. Details of the reverse repurchase agreements are as follows:

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

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 6, “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, 2019 (“fiscal 2019”).

Revision of Previously Reported Financial Information

The Company has historically classified certain fees collected from worksite employers for certain benefits within PEO revenues, and the associated costs of these benefits have historically been classified within operating expenses as PEO zero-margin benefits pass-through costs in the Company's Statements of Consolidated Earnings. During the quarter ended September 30, 2019, management determined that the Company does not retain risk and is acting as the agent, rather than as the primary obligor, for a portion of the fees collected for worksite employee benefits and the worksite employer is primarily responsible for fulfilling certain aspects of the service and has discretion in establishing price. Accordingly, the accompanying Statements of Consolidated Earnings for the three months ended September 30, 2018 has been revised to correct the amounts previously reported on a gross basis to a net basis by reducing PEO revenues and operating expenses for associated costs of an equal amount, as follows:

	Three Months Ended
	September 30, 2018
	As reported		Revision		As revised
PEO revenues	$	986.1	(12.9	)	$	973.2
TOTAL REVENUES	3,323.2		(12.9	)	3,310.3
Operating expenses	1,709.9		(12.9	)	1,697.0
Total Expenses	2,690.3		(12.9	)	2,677.4
EARNINGS BEFORE INCOME TAXES	646.8		—		646.8
Provision for income taxes	141.4		—		141.4
NET EARNINGS	$	505.4	—		$	505.4

In addition, the revised amounts for the fiscal year ended June 30, 2019 are as follows:

	Twelve Months Ended
	June 30, 2019
	As reported		Revision		As revised
PEO revenues	$	4,237.5	(65.0	)	$	4,172.5
TOTAL REVENUES	14,175.2		(65.0	)	14,110.2
Operating expenses	7,145.9		(65.0	)	7,080.9
Total Expenses	11,280.7		(65.0	)	11,215.7
EARNINGS BEFORE INCOME TAXES	3,005.6		—		3,005.6
Provision for income taxes	712.8		—		712.8
NET EARNINGS	$	2,292.8	—		$	2,292.8

The correction of these previously reported amounts had no impact on the Company's earnings before income taxes, net earnings, consolidated financial condition or cash flows. In addition, corresponding revisions have been made elsewhere in the Company's consolidated footnote disclosures, where applicable, including its Interim Financial Data by Segment disclosure.

Commitments and Contingencies

Commitments and Contingencies

In June 2018, a potential class action complaint was filed against ADP in the Circuit Court of Cook County, Illinois. The complaint asserts that ADP violated the Illinois Biometric Privacy Act, was negligent and unjustly enriched itself in connection with its collection, use and storage of biometric data of employees of its clients who are residents of Illinois in connection with certain services provided by ADP to clients in Illinois. The complaint seeks statutory and other unspecified monetary damages, injunctive relief and attorney’s fees. In addition, similar potential class action complaints have been filed in Illinois state courts against ADP and/or certain of its clients with respect to the collection, use and storage of biometric data of the employees of these clients. All of these claims are still in their earliest stages and the Company is unable to estimate any reasonably possible loss, or range of loss, with respect to these matters. The Company intends to vigorously defend against these lawsuits.

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.

Schedule of New Accounting Pronouncements and Changes in Accounting Principles

Recently Issued Accounting Pronouncements

The following table summarizes recent ASU's issued by the Financial Accounting Standards Board (“FASB”) which have been assessed:

Standard	Description	Effective Date	Effect on Financial Statements or Other Significant Matters
ASU 2018-14 Compensation-Retirement Benefits-Defined Benefit Plans	This update modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year, and (b) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for post-retirement health care benefits. Additional disclosures include descriptions of significant gains and losses affecting the benefit obligation for the period. The amendments in ASU 2018-14 would need to be applied on a retrospective basis.	July 1, 2021 (Fiscal 2022)	The adoption of this guidance will modify disclosures but will not have an impact on the Company's consolidated results of operations, financial condition, or cash flows.

Standard	Description	Effective Date	Effect on Financial Statements or Other Significant Matters
ASU 2018-13 Fair Value Measurement	This update modifies the disclosure requirements on fair value measurements. Certain disclosures in ASU 2018-13 would need to be applied on a retrospective basis and others on a prospective basis.	July 1, 2020 (Fiscal 2021)	The adoption of this guidance will modify disclosures but will not have an impact on the Company's consolidated results of operations, financial condition, or cash flows.
ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	This update introduces the current expected credit loss (CECL) model, which will require an entity to measure credit losses for certain financial instruments and financial assets, including trade receivables. Under this update, on initial recognition and at each reporting period, an entity will be required to recognize an allowance that reflects the entity’s current estimate of credit losses expected to be incurred over the life of the financial instrument. In addition, this update modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination.	July 1, 2020 (Fiscal 2021)	The adoption of this guidance will not have a material impact on its consolidated results of operations, financial condition, or cash flows.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

New Accounting Pronouncements

New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Effective July 1, 2019, the Company adopted accounting standard update (“ASU”) 2016-02, “Leases (ASC 842)” under the optional transition method. As a result, the Company recorded on the Consolidated Balance Sheets total operating lease right-of-use (“ROU”) assets of $573.3 million and total operating lease liabilities of $522.6 million, as of the adoption date. The adoption did not have an impact on our Statements of Consolidated Earnings or Statements of Consolidated Cash Flows. Refer to Note 7 for further details.

Recently Issued Accounting Pronouncements

The following table summarizes recent ASU's issued by the Financial Accounting Standards Board (“FASB”) which have been assessed:

Standard	Description	Effective Date	Effect on Financial Statements or Other Significant Matters
ASU 2018-14 Compensation-Retirement Benefits-Defined Benefit Plans	This update modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year, and (b) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for post-retirement health care benefits. Additional disclosures include descriptions of significant gains and losses affecting the benefit obligation for the period. The amendments in ASU 2018-14 would need to be applied on a retrospective basis.	July 1, 2021 (Fiscal 2022)	The adoption of this guidance will modify disclosures but will not have an impact on the Company's consolidated results of operations, financial condition, or cash flows.

Standard	Description	Effective Date	Effect on Financial Statements or Other Significant Matters
ASU 2018-13 Fair Value Measurement	This update modifies the disclosure requirements on fair value measurements. Certain disclosures in ASU 2018-13 would need to be applied on a retrospective basis and others on a prospective basis.	July 1, 2020 (Fiscal 2021)	The adoption of this guidance will modify disclosures but will not have an impact on the Company's consolidated results of operations, financial condition, or cash flows.
ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	This update introduces the current expected credit loss (CECL) model, which will require an entity to measure credit losses for certain financial instruments and financial assets, including trade receivables. Under this update, on initial recognition and at each reporting period, an entity will be required to recognize an allowance that reflects the entity’s current estimate of credit losses expected to be incurred over the life of the financial instrument. In addition, this update modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination.	July 1, 2020 (Fiscal 2021)	The adoption of this guidance will not have a material impact on its consolidated results of operations, financial condition, or cash flows.

Interim Financial Data by Segment

Interim Financial Data by Segment

Based upon similar economic and operational characteristics, the Company’s strategic business units have been aggregated into the following two reportable segments: Employer Services and PEO Services. The primary components of the “Other” segment 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, non-recurring gains and losses, the elimination of intercompany transactions, and interest expense. Certain revenues and expenses are charged to the reportable segments at a standard rate for management reasons. Other costs are recorded based on management responsibility. Beginning in the first quarter of fiscal 2020, the Company made changes to the allocation methodology for certain corporate allocations, in both the current period and the prior period in the table below, which did not materially affect reportable segment results. In addition, the segment results in the table below reflect the impact of the revision to PEO revenues for comparability. Refer to Note 1 to our consolidated financial statements for more information on this revision.

Income Tax Disclosure [Abstract]

Income Taxes

Income TaxesThe effective tax rate for the three months ended September 30, 2019 and 2018 was 21.2% and 21.9%, respectively. The decrease in the effective tax rate is due to an increase in tax incentives related to our software development activities and a decrease in reserves for uncertain tax positions in the three months ended September 30, 2019. This was partially offset by a decrease in the excess tax benefit on stock-based compensation in the three months ended September 30, 2019 and the income tax benefit related to the Tax Cuts and Job Act in the three months ended September 30, 2018.

Leases [Abstract]

Lessee, Operating Leases [Text Block]

Leases

During the first quarter of the fiscal year ending June 30, 2020 ("fiscal 2020"), the Company adopted ASC 842 using the optional transition method under which financial results reported in periods prior were not adjusted and continue to be reported in accordance with historic accounting under ASC 840 - Leases.

The Company elected the following practical expedients permitted under the lease standard:

• The Company did not reassess prior conclusions about lease identification, lease classification or initial direct costs, and did not use hindsight for leases existing at adoption date.

• The Company did not record leases with an initial term of 12 months or less on the consolidated balance sheet but continues to expense them on a straight-line basis over the lease term.

• The Company elected to combine lease and non-lease components for our facilities leases only. Non-lease components consist primarily of maintenance services.

The Company records leases on the consolidated balance sheets as operating lease 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 Company has entered into operating lease agreements for facilities and equipment. The Company's leases have remaining lease terms of up to approximately ten years. Operating lease ROU assets and operating lease liabilities are recognized at the lease commencement date based on the present value of the lease payments over the lease term. The lease liabilities are measured by discounting future lease payments at the Company’s collateralized incremental borrowing rate for financing instruments of a similar term, unless the implicit rate is readily determinable. ROU assets also include adjustments related to prepaid or deferred lease payments and lease incentives. As of September 30, 2019, total operating lease ROU assets were $504.0 million, current and long-term operating lease liabilities were approximately $103.3 million and $355.4 million, respectively. The difference between total ROU assets and total lease liabilities are primarily attributable to pre-payments of our obligations and the recognition of various lease incentives.

The components of operating lease expense were as follows for the three months ended September 30, 2019:

Operating lease cost	$	44.2
Short-term lease cost	2.7
Variable lease cost	1.3
Total operating lease cost	$	48.2

Information related to our operating lease ROU assets and operating lease liabilities was as follows:

	September 30, 2019
Cash paid for operating lease liabilities	$	40.2
Operating lease ROU assets obtained in exchange for new operating lease liabilities	$	6.7
Weighted-average remaining lease term (in years)	6
Weighted-average discount rate	2.4		%

As of September 30, 2019, maturities of operating lease liabilities are as follows:

Nine months ending June 30, 2020	$	87.0
Twelve months ending June 30, 2021	97.1

Revenue from Contract with Customer [Abstract]

Revenue

Revenue

Based upon similar operational and economic characteristics, the Company’s revenues are disaggregated by its three strategic pillars: HCM (“HCM”), HR Outsourcing (“HRO”), and Global (“Global”) Solutions with separate disaggregation for PEO zero-margin benefits pass-through revenues and client fund 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.

HCM provides a suite of product offerings that assist employers of all types and sizes in all stages of the employment cycle, from recruitment to retirement. Global is generally consistent with the types of services provided within HCM but represents geographies outside of the United States and includes our multinational offerings. HCM and Global revenues are primarily attributable to fees for providing solutions for payroll, benefits, talent, retirement services and HR processing and fees charged to implement the Company's solutions for clients.

HRO provides a comprehensive human resources outsourcing solution, including offering benefits, providing workers’ compensation insurance, and administering state unemployment insurance, among other human resources functions. This revenue is primarily driven by the PEO. Amounts collected from PEO worksite employers include payroll, fees for benefits, and an administrative fee that also includes payroll taxes, fees for workers’ compensation and state unemployment taxes. The payroll and payroll taxes collected from the worksite employers are presented in revenue net, as the Company does not retain risk and acts as an agent with respect to this aspect of the PEO arrangement. With respect to the payroll and payroll taxes, the worksite employer is primarily responsible for providing the service and has discretion in establishing wages. The fees collected from the worksite employers for benefits (i.e., PEO benefits pass-throughs), workers’ compensation and state unemployment taxes are presented in revenues and the associated costs of benefits, workers’ compensation and state unemployment taxes are included in operating expenses, as the Company acts as a principal with respect to this aspect of the arrangement. With respect to these fees, the Company is primarily responsible for fulfilling the service and has discretion in establishing price. The Company has further disaggregated HRO to separate out its PEO zero-margin benefits pass-through revenues.

The Company recognizes client fund interest revenues on collected but not yet remitted funds held for clients in revenues as earned, as the collection, holding and remittance of these funds are critical components of providing these services.

The following tables provide details of revenue by our strategic pillars with disaggregation for PEO zero-margin benefits pass-throughs and client fund interest, and includes a reconciliation to the Company’s reportable segments:

	Three Months Ended

Total Segment Revenues	$	2,338.2	$	974.9	$	(2.8	)	$	3,310.3

Contract Balances

The timing of revenue recognition for our HCM, HRO and Global Solutions 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 revenue related to set up fees for the three months ended September 30, 2019 were as follows:

Contract Liability
Contract liability, July 1, 2019	$	563.4
Recognition of revenue included in beginning of year contract liability	(45.4		)

In fiscal 2018, the Company offered a voluntary early retirement program (“VERP”) to certain eligible U.S.-based associates aged 55 or above with at least 10 years of service. During the three months ended September 30, 2018, the Company recorded $15.3 million of non-cash settlement charges and special termination benefits.

Stock-Based Compensation Plans

Stock-based Compensation Plans. Stock-based compensation consists of the following:

• Stock Options.  Stock options are granted to employees at exercise prices equal to the fair market value of the Company's common stock on the dates of grant. Stock options generally vest ratably over 4 years and have a term of 10 years. Compensation expense is measured based on the fair value of the stock option on the grant date and recognized on a straight-line basis over the vesting period. Stock options are forfeited if the employee ceases to be employed by the Company prior to vesting.

• Restricted Stock.

• Time-Based Restricted Stock and Time-Based Restricted Stock Units. Time-based restricted stock and time-based restricted stock units granted September 1, 2018 and after generally vest ratably over 3 years. Time-based restricted stock and time-based restricted stock units granted prior to September 1, 2018 are generally subject to a vesting period of 2 years. Awards are forfeited if the employee ceases to be employed by the Company prior to vesting.

Time-based restricted stock cannot be transferred during the vesting period. Compensation expense relating to the issuance of time-based restricted stock is measured based on the fair value of the award on the grant date and recognized on a straight-line basis over the vesting period. Dividends are paid on shares awarded under the time-based restricted stock program.

Time-based restricted stock units are settled in cash and cannot be transferred during the vesting period. Compensation expense relating to the issuance of time-based restricted stock units is recorded over the vesting period and is initially based on the fair value of the award on the grant date and is subsequently remeasured at each reporting date during the vesting period based on the change in the ADP stock price. No dividend equivalents are paid on units awarded under the time-based restricted stock unit program.

• Performance-Based Restricted Stock and Performance-Based Restricted Stock Units. Performance-based restricted stock and performance-based restricted stock units generally vest over a one to three year performance period and a subsequent service period of up to 38 months. Under these programs, the Company communicates “target awards” at the beginning of the performance period with possible payouts at the end of

the performance period ranging from 0% to 150% of the “target awards.” Awards are generally forfeited if the employee ceases to be employed by the Company prior to vesting.

Performance-based restricted stock cannot be transferred during the vesting period. Compensation expense relating to the issuance of performance-based restricted stock is recognized over the vesting period based on the fair value of the award on the grant date with subsequent adjustments to the number of shares awarded during the performance period based on probable and actual performance against targets. After the performance period, if the performance targets are achieved, employees are eligible to receive dividends during the remaining vesting period on shares awarded under the performance-based restricted stock program.

Performance-based restricted stock units cannot be transferred and are settled in either cash or stock, depending on the employee's home country. Compensation expense relating to the issuance of performance-based restricted stock units settled in cash is recognized over the vesting period initially based on the fair value of the award on the grant date with subsequent adjustments to the number of units awarded during the performance period based on probable and actual performance against targets. In addition, compensation expense is remeasured at each reporting period during the vesting period based on the change in the ADP stock price. Compensation expense relating to the issuance of performance-based restricted stock units settled in stock is recorded over the vesting period based on the fair value of the award on the grant date with subsequent adjustments to the number of units awarded based on the probable and actual performance against targets. Dividend equivalents are paid on awards under the performance-based restricted stock unit program.

• Employee Stock Purchase Plan. The Company offers an employee stock purchase plan that allows eligible employees to purchase shares of common stock at a price equal to 95% of the market value for the Company's common stock on the last day of the offering period. This plan has been deemed non-compensatory and, therefore, no compensation expense has been recorded.

The Company currently utilizes treasury stock to satisfy stock option exercises, issuances under the Company's employee stock purchase plan, and restricted stock awards. From time to time, the Company may repurchase shares of its common stock under its authorized share repurchase programs. The Company repurchased 1.9 million and 1.6 million shares in the three months ended September 30, 2019 and 2018, respectively. 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 months ended September 30, 2019 and 2018, respectively:

	Three Months Ended
	September 30,
	2019		2018
Operating expenses	$	4.0	$	5.4
Selling, general and administrative expenses	28.3		28.0
System development and programming costs	4.8		5.0
Total stock-based compensation expense	$	37.1	$	38.4

As of September 30, 2019, the total remaining unrecognized compensation cost related to non-vested stock options, restricted stock units, and restricted stock awards amounted to $32.9 million, $83.9 million, and $142.7 million, respectively, which will be amortized over the weighted-average remaining requisite service periods of 2.5 years, 1.8 years, and 2.4 years, respectively.
