Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation A. Description of Business CDK Global, Inc. (the "Company" or "CDK") is a leading global provider of integrated information technology and digital marketing solutions to the automotive retail and adjacent industries. The Company’s solutions automate and integrate all parts of the buying process from targeted digital advertising and marketing campaigns to the sale, financing, insuring, parts supply, repair, and maintenance of vehicles. The Company is organized into two main operating groups. The Company's first operating group is CDK North America which is comprised of two reportable segments, Retail Solutions North America and Advertising North America. The second operating group, which is also a reportable segment, is CDK International. In addition, the Company has an "Other" segment, the primary components of which are corporate allocations and other expenses not recorded in the segment results. Refer to Note 14 for further information. B. Basis of Preparation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect assets, liabilities, revenues, and expenses that are reported in the accompanying financial statements and footnotes thereto. Actual results may differ from those estimates and assumptions. The accompanying condensed consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods. Interim financial results are not necessarily indicative of financial results for a full year. The financial statements 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, 2017

Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of significant accounting policies	Summary of Significant Accounting Policies A. Revenue Recognition The Company recognizes software revenues in accordance with Accounting Standards Codification (“ASC”) 985-605, “Software - Revenue Recognition,” and non-software related revenue, including Software-as-a-Service (“SaaS”), in accordance with ASC 605, "Revenue Recognition" ("ASC 605"). The Company generates revenues from four categories: subscription, digital advertising, transactional services, and other. Taxes collected from customers and remitted to governmental authorities are presented on a net basis; that is, such taxes are excluded from revenues. Subscription. In the Retail Solutions North America (“RSNA”) and CDK International (“CDKI”) segments, CDK provides software and technology solutions for automotive retailers and original equipment manufacturers ("OEMs"), which includes: • Dealer Management Systems (“DMSs”) and layered applications, where the software may be installed onsite at the customer’s location, or hosted and provided on a SaaS basis, including ongoing maintenance and support; • Interrelated services such as installation, initial training, and data updates; • Websites, search marketing, and reputation management services (RSNA only); and • Hardware on a service basis, meaning no specific assets are identified or a substantive right of substitution exists. Revenues for term licenses are recognized ratably over the software license term, as vendor-specific objective evidence of the fair values of the individual elements in the sales arrangement does not exist. Revenue recognition commences at the installation dates, when customer acceptance has occurred, and collectability of a determinable amount is probable. In the case of hosted applications, the customer does not have the contractual right to take possession of the software and the items delivered at the outset of the contract (i.e., installation, training, etc.) do not have value to the customer without the software license and ongoing support and maintenance. Any upfront fees charged in the case of hosted arrangements are recognized ratably over the expected benefit period of the arrangement, typically five years. The unrecognized portion of these revenue elements is recorded as deferred revenue. Advertising services. In the Advertising North America (“ANA”) segment, the Company receives revenues from the placement of internet advertising for automotive retailers and OEMs. Advertising revenues are recognized when the services are rendered. Transaction revenues . In the RSNA segment, the Company receives fees per transaction for providing auto retailers interfaces with third parties to process credit reports, vehicle registrations, and automotive equity mining. Revenue is recognized at the time the services are rendered. Transaction revenues are recorded in revenues gross of costs incurred for credit report processing, vehicle registrations, and automotive equity mining as the Company is contractually responsible for providing the service, software, and/or connectivity to the customers, and therefore, the Company is the primary obligor under ASC 605. Other . The Company provides consulting and professional services and sells hardware such as laser printers, networking and telephony equipment, and related items. These revenues are recognized upon their delivery or service completion. B. Deferred Costs Costs to deliver services are expensed to cost of revenues as incurred with the exception of specific costs directly related to transition or installation activities, including payroll-related costs for the Company's implementation and training teams, as well as commission costs for the sale. These costs are deferred and expensed proportionately over the same period that the deferred revenues are recognized as revenues. Deferred amounts are monitored regularly to ensure appropriate asset and expense recognition. Current deferred costs classified within other current assets on the condensed consolidated balance sheets were $93.2 million and $94.4 million as of September 30, 2017 and June 30, 2017 , respectively. Long-term deferred costs classified within other assets on the condensed consolidated balance sheets were $109.4 million and $115.0 million as of September 30, 2017 and June 30, 2017 , respectively. C. Funds Receivable and Funds Held for Clients and Client Fund Obligations Funds receivable and funds held for clients represent amounts received or expected to be received from clients in advance of performing titling and registration services on behalf of those clients. These amounts are classified within other current assets on the condensed consolidated balance sheets. The total amount due to remit for titling and registration obligations with the department of motor vehicles is recorded to client fund obligations which is classified as accrued expenses and other current liabilities on the condensed consolidated balance sheet. Funds receivable was $28.1 million and $25.7 million , and funds held for clients was $7.9 million and $7.9 million as of September 30, 2017 and June 30, 2017 , respectively. Client fund obligation was $36.0 million and $33.6 million as of September 30, 2017 and June 30, 2017 , respectively. D. Computer Software to be Sold, Leased, or Otherwise Marketed The Company's policy provides for the capitalization of certain costs of computer software to be sold, leased, or otherwise marketed. The Company's policy provides for the capitalization of all software production costs upon reaching technological feasibility for a specific product. Technological feasibility is attained when software products have a completed working model whose consistency with the overall product design has been confirmed by testing. Costs incurred prior to the establishment of technological feasibility are expensed as incurred. The establishment of technological feasibility requires judgment by management and in many instances is only attained a short time prior to the general release of the software. Maintenance-related costs are expensed as incurred. Pursuant to this policy, the Company recognized expenses of $38.0 million and $38.7 million for the three months ended September 30, 2017 and 2016 , respectively. These expenses were classified within cost of revenues on the condensed consolidated statements of operations. E. Fair Value of Financial Instruments The Company determines the fair value of financial instruments in accordance with accounting standards pertaining to fair value measurements. Such standards define fair value and establish a framework for measuring fair value in accordance with GAAP. Cash and cash equivalents, accounts receivable, other current assets, accounts payable, and other current liabilities are reflected in the condensed consolidated balance sheets at cost, which approximates fair value due to the short-term nature of these instruments. The carrying value of the Company's term loan facilities (as described in Note 8), including accrued interest, approximates fair value based on the Company's current estimated incremental borrowing rate for similar types of arrangements. The approximate aggregate fair value of the Company's senior notes as of September 30, 2017 was $1,412.4 million based on quoted market prices for the same or similar instruments and the carrying value was $1,350.0 million

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Recently Issued Accounting Pronouncements In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other.” ASU 2017-04 simplifies the accounting for goodwill impairment by eliminating Step 2 of the current goodwill impairment test, which required a hypothetical purchase price allocation. Goodwill impairment will now be the amount by which the reporting unit’s carrying value exceeds its fair value, limited to the carrying value of the goodwill. ASU 2017-04 is effective for financial statements issued for fiscal years, and interim periods beginning after December 15, 2019. The adoption of ASU 2017-04 is not expected to have a material impact on the Company's consolidated results of operations, financial condition, or cash flows. In November 2016, the FASB issued ASU 2016-18, “Restricted Cash.” ASU 2016-18 clarifies cash flow presentation for restricted cash. ASU 2016-18 is effective for financial statements issued for fiscal years, and interim periods beginning after December 15, 2017. The adoption of ASU 2016-18 will not have a material impact on the Company's consolidated statements of cash flows. In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments (Topic 230).” ASU 2016-15 addresses eight specific cash flow issues where there is diversity in practice in how these certain cash receipts and cash payments are presented and classified in the statements of cash flows. ASU 2016-15 is effective for financial statements issued for fiscal years, and interim periods beginning after December 15, 2017. The adoption of ASU 2016-15 will not have a material impact on the Company's consolidated statements of cash flows. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires that lessees recognize right-of-use assets and lease liabilities for any lease classified as either a finance or operating lease that is not considered short-term. The accounting applied by lessors is largely consistent with the existing lease standard. ASU 2016-02 is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2018. The Company has obligations under lease agreements for facilities and equipment, which are classified as operating leases under the existing lease standard. While the Company is still evaluating the impact that ASU 2016-02 will have on the consolidated results of operations, financial condition, or cash flows, the Company's financial statements will reflect an increase in both assets and liabilities due to the requirement to recognize right-of-use assets and lease liabilities on the consolidated balance sheets for its facility and equipment leases. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 requires an entity to recognize revenue depicting the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will also result in enhanced revenue related disclosures. The guidance permits two methods of adoption: 1) retrospectively to each prior reporting period presented (full retrospective), or 2) retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective). In July 2015, the FASB deferred the effective date of ASU 2014-09 by one year and subsequently issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date." As a result, the standard and subsequent amendments thereto, will be effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2017. In fiscal 2017, the Company established a cross-functional implementation team to evaluate the impact of the new standard on its revenue contracts including reviewing current accounting policies, evaluating new disclosure requirements, identifying appropriate changes to business processes, information technology systems, and internal controls to support revenue recognition, and disclosure under the new guidance. The Company has made significant progress in its qualitative assessment of the impact of the new revenue recognition standard; however, efforts to quantify the impact upon adoption remain ongoing. The Company has concluded that it will adopt this standard on a modified retrospective basis, which will result in a cumulative effect adjustment to retained earnings when the standard is adopted on July 1, 2018. While the Company continues to evaluate the impact of ASU 2014-09, and related ASUs, on its consolidated results of operations, financial condition, or cash flows, the following determinations have been made: • Under the current accounting guidance for software, ASC 985-605, revenues for onsite licenses are recognized ratably over the software license term, as CDK lacks vendor-specific objective evidence of the fair values of the individual elements of the sales arrangement; however, upon adoption of ASC 606 revenues may be recognized upon installation of onsite software based on estimated standalone selling price at the time of the sale. This will result in a cumulative adjustment (an increase) to beginning retained earnings, for which management is completing its evaluation and quantifying the impact. • Aside from revenues for onsite software licenses discussed above, the Company currently accounts for the majority of its revenues, including SaaS and other service arrangements under ASC 605. Under both the existing revenue standard, ASC 605, and the new standard pending adoption, ASC 606, the revenue for ongoing services will be recognized ratably over the term of arrangement; however, management is currently evaluating the impact of other aspects of the standard, including variable consideration. •

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring During the fiscal year ended June 30, 2015 ("fiscal 2015"), the Company initiated a three -year business transformation plan intended to increase operating efficiency and improve the Company's cost structure within its global operations. The business transformation plan is expected to produce significant benefits in the Company's long-term business performance. As the Company executes the business transformation plan, the Company continually monitors, evaluates and refines its structure, including its design, goals, term and estimate of total restructuring expenses. As part of this process, the Company extended the business transformation plan by one year to June 30, 2019 ("fiscal 2019"), and updated its current estimate of total restructuring expenses under the business transformation plan to approximately $70 million through fiscal 2019. Restructuring expenses associated with the business transformation plan included employee-related costs, which represent severance and other termination-related benefits calculated based on long-standing benefit practices and local statutory requirements, and contract termination costs. The Company recognized $6.5 million and $1.1 million of restructuring expenses for the three months ended September 30, 2017 and 2016 , respectively. Since the inception of the business transformation plan in the fourth quarter of fiscal 2015, the Company has recognized cumulative restructuring expenses of $47.5 million . Restructuring expenses are presented separately on the condensed consolidated statements of operations. Restructuring expenses are recorded in the Other segment, as these initiatives are predominantly centrally directed and are not included in internal measures of segment operating performance. Accruals for restructuring expenses were included within accrued expenses and other current liabilities on the consolidated balance sheets as of September 30, 2017 and June 30, 2017 . The following table summarizes the activity for the restructuring accrual for the three months ended September 30, 2017 : Employee-Related Costs Contract Termination Costs Total Costs Balance as of June 30, 2017 $ 6.4 $ 2.4 $ 8.8 Charges 5.7 1.1 6.8 Cash payments (5.1 ) (0.5 ) (5.6 ) Adjustments (0.2 ) (0.1 ) (0.3 ) Balance as of September 30, 2017 $ 6.8 $ 2.9 $ 9.7

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share The numerator for both basic and diluted earnings per share is net earnings attributable to CDK. The denominator for basic and diluted earnings per share is based upon the weighted-average number of shares of the Company's common stock outstanding during the reporting periods. Diluted earnings per share also reflects the dilutive effect of unexercised in-the-money stock options and unvested restricted stock. Holders of certain stock-based compensation awards are eligible to receive dividends as described in Note 9. Net earnings allocated to participating securities were not significant for the three months ended September 30, 2017 and 2016 . The following table summarizes the components of basic and diluted earnings per share: Three Months Ended September 30, 2017 2016 Net earnings attributable to CDK $ 81.3 $ 76.9 Weighted-average shares outstanding: Basic 140.1 150.2 Effect of employee stock options 0.4 0.8 Effect of employee restricted stock 0.9 0.7 Diluted 141.4 151.7 Basic earnings attributable to CDK per share $ 0.58 $ 0.51 Diluted earnings attributable to CDK per share $ 0.57 $ 0.51 The weighted-average number of shares outstanding used in the calculation of diluted earnings per share does not include the effect of the following anti-dilutive securities.

The revolving credit facility provides up to $300.0 million of borrowing capacity and includes a sub-limit of up to $100.0 million for loans in Euro and Pound Sterling. In addition, the revolving credit facility contains an accordion feature that allows for an increase in the available borrowing capacity of up to $100.0 million , subject to the agreement of lenders under the revolving credit facility or other financial institutions that become lenders to extend commitments as part of the increased revolving credit facility. Borrowings under the revolving credit facility are available for general corporate purposes. The revolving credit facility will mature on September 30, 2019 , subject to no more than two one -year extensions if lenders holding a majority of the revolving commitments approve such extensions. The revolving credit facility is unsecured and loans thereunder bear interest, at the Company's option, at (a) the rate at which deposits in the applicable currency are offered in the London interbank market (or, in the case of borrowings in Euro, the European interbank market) plus margins varying from 1.125% to 2.000% per annum based on the Company's senior, unsecured non-credit-enhanced, long-term debt ratings from Standard & Poor's Ratings Group and Moody's Investors Services Inc. (the "Ratings") or (b) solely in the case of U.S. dollar loans, (i) the highest of (A) the prime rate of JPMorgan Chase Bank, N.A., (B) a rate equal to the average of the overnight federal funds rate with a maturity of one day plus a margin of 0.750% per annum and (C) the rate at which dollar deposits are offered in the London interbank market for a one-month interest period plus 1.000% plus (ii) margins varying from 0.125% to 1.000% per annum based on the Ratings. The unused portion of the revolving credit facility is subject to commitment fees ranging from 0.125% to 0.350% per annum based on the Ratings. Term Loan Facilities The Company has two five -year $250.0 million senior unsecured term loan facilities that mature on September 16, 2019 (the "2019 term loan facility") and December 14, 2020 (the "2020 term loan facility"), respectively. On December 9, 2016, the Company entered into a five -year $400.0 million senior unsecured term loan facility that matures on December 9, 2021 (the "2021 term loan facility"). The 2019 term loan facility, 2020 term loan facility, and 2021 term loan facility are together referred to as the "term loan facilities." The term loan facilities are subject to amortization in equal quarterly installments of 1.25% of the aggregate original principal amount of the term loans made on the closing dates, with any unpaid principal amount to be due and payable on the maturity date. The 2019 and 2020 term loan facilities bear interest at the same calculations as are applicable to dollar loans under the revolving credit facility. The interest rate per annum on both the 2019 and 2020 term loan facilities was 2.99% as of September 30, 2017 and 2.98% as of June 30, 2017 . The 2021 term loan bears interest, at the Company's option, at (a) the rate at which deposits in the applicable currency are offered in the London interbank market (or, in the case of borrowings in Euro, the European interbank market) plus margins varying from 1.250% to 2.500% per annum based on the Company's senior, unsecured non-credit-enhanced, long-term debt ratings from Standard & Poor's Ratings Group and Moody's Investors Services Inc. (the "Ratings") or b) solely in the case of U.S. dollar loans, (i) the highest of (A) the prime rate of Bank of America, (B) a rate equal to the average of the overnight federal funds rate with a maturity of one day plus a margin of 0.750% per annum and (C) the rate at which dollar deposits are offered in the London interbank market for a one-month interest period plus 1.000% plus (ii) margins varying from 0.250% to 1.500% per annum based on the Ratings. The interest rate per annum on the 2021 term loan facility was 2.99% as of September 30, 2017 and 2.98% as of June 30, 2017 . Restrictive Covenants and Other Matters The revolving credit facility and the term loan facilities are together referred to as the "credit facilities." The credit facilities contain various covenants and restrictive provisions that limit the Company's subsidiaries' ability to incur additional indebtedness; the Company's ability to consolidate or merge with other entities; and the Company's subsidiaries' ability to incur liens, enter into sale and leaseback transactions, and enter into agreements restricting the ability of the Company's subsidiaries to pay dividends. If the Company fails to perform the obligations under these and other covenants, the revolving credit facility could be terminated and any outstanding borrowings, together with accrued interest, under the credit facilities could be declared immediately due and payable. The credit facilities also have, in addition to customary events of default, an event of default triggered by the acceleration of the maturity of any other indebtedness the Company may have in an aggregate principal amount in excess of $75.0 million . The credit facilities also contain financial covenants that will provide that (i) the ratio of total consolidated indebtedness to consolidated EBITDA shall not exceed 3.50 to 1.00 and (ii) the ratio of consolidated EBITDA to consolidated interest expense shall be a minimum of 3.00 to 1.00 . On December 9, 2016, the Company entered into (i) an Amendment to its Credit Agreement that covered the revolving credit facility and the 2019 term loan facility (the “2014 amendment”), and (ii) an Amendment to its Credit Agreement that covered the 2020 term loan facility (the “2015 amendment”). The 2014 amendment and the 2015 amendment amended certain “bail-in” language relating to EEA Financial Institutions and make certain changes to the definitions of “Change in Control,” “Consolidated EBITDA,” “Defaulting Lender,” and “Eligible Assignee.” Senior Notes On October 14, 2014 , the Company completed an offering of 3.30% unsecured senior notes with a $250.0 million aggregate principal amount due in 2019 (the "2019 notes") and 4.50% senior notes with a $500.0 million aggregate principal amount due in 2024 (the "2024 notes"). The issuance price of the 2019 and 2024 notes was equal to the stated value. Interest is payable semi-annually on April 15 and October 15 of each year, and payment commenced on April 15, 2015 . The interest rate payable on each applicable series of 2019 and 2024 notes is subject to adjustment from time to time if the credit ratings assigned to any series of 2019 and 2024 notes by the rating agencies is downgraded (or subsequently upgraded). The 2019 notes will mature on October 15, 2019 , and the 2024 notes will mature on October 15, 2024 . The 2019 notes and 2024 notes are redeemable at the Company's option prior to September 15, 2019 for the 2019 notes and prior to July 15, 2024 for the 2024 notes at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the 2019 notes or 2024 notes to be redeemed, and (ii) the sum of the present value of the remaining scheduled payments (as defined in the agreement), plus in each case, accrued and unpaid interest thereon. Subsequent to September 15, 2019 and July 15, 2024 , the redemption price for the 2019 notes and the 2024 notes, respectively, will equal 100% of the aggregate principal amount of the notes redeemed, plus accrued and unpaid interest thereon. On May 15, 2017 , the Company completed an offering of 4.875% unsecured senior notes with a $600.0 million aggregate principal amount due in 2027 (the " 2027 notes," together with the " 2024 notes" and the 2019 notes, the "senior notes"). The issuance price of the 2027 notes was equal to the stated value. Interest is payable semi-annually on June 1 and December 1 of each year, and payment will commence on December 1, 2017 . The 2027 notes will mature on June 1, 2027 . The 2027 notes are redeemable at the Company's option prior to June 1, 2022 in whole or in part at a redemption price equal to 100% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, plus the applicable "make-whole" premium. Subsequent to June 1, 2022 , the Company may redeem the 2027 notes at a price equal to: (i) 102.438% of the aggregate principal amount of the 2027 notes redeemed prior to June 1, 2023 ; (ii) 101.625% of the aggregate principal amount of the notes redeemed on or after June 1, 2023 but prior to June 1, 2024 ; (iii) 100.813% of the aggregate principal amount of the 2027 notes redeemed on or after June 1, 2024 but prior to June 1, 2025 ; and (iv) 100.000% of the aggregate principal amount of the 2027 notes redeemed thereafter. The senior notes are general unsecured obligations of the Company and are not guaranteed by any of the Company's subsidiaries. The senior notes rank equally in right of payment with the Company's existing and future unsecured unsubordinated obligations, including the credit facilities. The senior notes contain covenants restricting the Company's ability to incur additional indebtedness secured by liens, engage in sale/leaseback transactions, and merge, consolidate, or transfer all or substantially all of the Company's assets. The senior notes are also subject to a change of control provision whereby each holder of the senior notes has the right to require the Company to purchase all or a portion of such holder's senior notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest upon the occurrence of both a change of control and a decline in the rating of the senior notes. In November 2016, Moody's and S&P lowered their credit ratings on the senior notes to Ba1 (Stable Outlook) from Baa3 (Negative Outlook) and to BB+ (Stable Outlook) from BBB- (Negative Outlook), respectively. The downgrades triggered interest rate adjustments for the 2019 and 2024 notes. Interest rates for the 2019 and 2024 notes increased to 3.80% from 3.30% , and to 5.00% from 4.50% , respectively, effective October 15, 2016. Capital Lease Obligations The Company has lease agreements for equipment, which are classified as capital lease obligations. The Company recognized the capital lease obligations and related leased equipment assets based on the present value of the minimum lease payments at lease inception. Unamortized Debt Financing Costs As of September 30, 2017 and June 30, 2017 , gross debt issuance costs related to debt instruments were $22.1 million and $21.7 million , respectively. Accumulated amortization was $5.8 million and $5.0 million as of September 30, 2017 and June 30, 2017 , respectively. Debt financing costs are amortized over the terms of the related debt instruments to interest expense on the consolidated and combined statement of operations. The Company's aggregate scheduled maturities of the long-term debt and capital lease obligations as of September 30, 2017 were as follows: Amount Twelve months ending September 30, 2018 $ 46.2 Twelve months ending September 30, 2019 232.6 Twelve months ending September 30, 2020 282.5 Twelve months ending September 30, 2021 210.6 Twelve months ending September 30, 2022 305.0 Thereafter 1,100.0 Total debt and capital lease obligations 2,176.9 Unamortized debt financing costs (16.3 ) Total debt and capital lease obligations, net of unamortized deferred financing costs $ 2,160.6

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation Incentive Equity Awards Granted by the Company The 2014 Omnibus Award Plan ("2014 Plan") provides for the granting of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, other stock-based awards, and performance compensation awards to employees, directors, officers, consultants, and advisors, and those of the Company's affiliates. The 2014 Plan provides for an aggregate of 12.0 million shares of the Company's common stock to be reserved for issuance and is effective for a period of ten years . The Company reissues treasury stock to satisfy issuances of common stock upon option exercise, equity vesting, or grants of time-based restricted stock. On September 30, 2014 , Automatic Data Processing, Inc. (“ADP”) distributed 100% of the common stock of the Company to the holders of record of Automatic Data Processing, Inc. (“ADP”) common stock as of September 24, 2014 (the "spin-off"). Prior to the spin-off, all employee equity awards (stock options and restricted stock) were granted by ADP. All subsequent awards, including all incentive equity awards converted from ADP awards, were granted under the 2014 Plan. The Company recognizes stock-based compensation expense associated with employee equity awards in net earnings based on the fair value of the awards on the date of grant. The Company accounts for forfeitures as they occur. Stock-based compensation primarily consisted of the following for the three months ended September 30, 2017 and 2016 : 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 date of grant. Stock options are issued under a graded vesting schedule and generally have a term of ten years . Compensation expense is measured based on the fair value of the stock option on the grant date and recognized over the requisite service period for each separately vesting portion of the stock option award. Upon termination of employment, unvested stock options are evaluated for forfeiture or modification, subject to the terms of the awards and Company policies. Time-Based Restricted Stock and Time-Based Restricted Stock Units. Time-based restricted stock and restricted stock units generally vest over a two to five -year period. Upon termination of employment, unvested stock options are evaluated for forfeiture or modification, subject to the terms of the awards and Company policies. Time-based restricted stock cannot be transferred during the vesting period. Compensation expense related 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. Employees are eligible to receive cash dividends on the CDK shares awarded under the time-based restricted stock program during the restricted period. Time-based restricted stock units are primarily settled in cash, but may also be settled in stock. Compensation expense related 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. Cash-settled, time-based restricted stock units are subsequently remeasured at each reporting date during the vesting period to the current stock value. No dividend equivalents are paid on units awarded under the time-based restricted stock unit program during the restricted period. Performance-Based Restricted Stock Units. Performance-based restricted stock units generally vest over a three -year performance period. 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 250% of the "target awards" plus any dividend equivalents, as described below. Certain performance-based restricted stock units are further subject to adjustment (increase or decrease) based on a market condition defined as the total shareholder return of the Company's common stock compared to a peer group of companies. Performance-based restricted stock units are settled in either cash or stock, depending on the employee’s home country, and cannot be transferred during the vesting period. Compensation expense related to the issuance of performance-based restricted stock units settled in cash is recorded over the vesting period, is initially based on the fair value of the award on the grant date, and is subsequently remeasured at each reporting date to the current stock value during the performance period, based upon the probability that the performance target will be met. Compensation expense related 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. Prior to settlement, dividend equivalents are earned on "target awards" under the performance-based restricted stock unit program. The following table represents stock-based compensation expense and the related income tax benefits for the three months ended September 30, 2017 and 2016 , respectively: Three Months Ended September 30, 2017 2016 Cost of revenues $ 1.1 $ 1.3 Selling, general and administrative expenses 7.0 8.5 Total pre-tax stock-based compensation expense $ 8.1 $ 9.8 Income tax benefit $ 2.8 $ 3.3 Stock-based compensation expense for the three months ended September 30, 2017 consisted of $6.8 million of expense related to equity classified awards and $1.3 million of expense related to liability classified awards. Stock-based compensation expense includes additional expense based on management's assessment that it is probable CDK's performance metrics for fiscal year ending June 30, 2018 ("fiscal 2018") associated with performance-based restricted stock units will exceed target. As of September 30, 2017, the total unrecognized compensation cost related to non-vested stock options, restricted stock units, and restricted stock awards was $ 2.7 million , $ 34.1 million , and $ 18.5 million , respectively, which will be amortized over the weighted-average remaining requisite service periods of 2.1 years, 1.8 years, and 1.6 years, respectively. The activity related to the Company's incentive equity awards from June 30, 2017 to September 30, 2017 consisted of the following: Stock Options Number of Options (in thousands) Weighted Average Exercise Price (in dollars) Options outstanding as of June 30, 2017 1,310 $ 39.70 Options granted 25 62.03 Options exercised (94 ) 27.60 Options canceled (38 ) 52.63 Options outstanding as of September 30, 2017 1,203 $ 40.70 Time-Based Restricted Stock and Time-Based Restricted Stock Units Number of Shares (in thousands) Number of Units (in thousands) Non-vested restricted units/shares as of June 30, 2017 497 214 Restricted shares/units granted 169 47 Restricted shares/units vested (176 ) (46 ) Restricted shares/units forfeited (18 ) (4 ) Non-vested restricted units/shares as of September 30, 2017 472 211 Performance-Based Restricted Stock Units Number of Units (in thousands) Non-vested restricted units as of June 30, 2017 742 Restricted units granted 29 Dividend equivalents 2 Restricted units vested (4 ) Restricted units forfeited (39 ) Non-vested restricted units as of September 30, 2017 730 The following table presents the assumptions used in the binomial model to determine the fair value of stock options granted during the three months ended September 30, 2017 : Risk-free interest rate 2.0 % Dividend yield 0.9 % Weighted-average volatility factor 24.5 % Weighted-average expected life (in years) 6.3 Weighted-average fair value (in dollars) $ 15.65

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Tax Matters Agreement The Company and ADP entered into a tax matters agreement as part of the spin-off that governs the rights and obligations of both parties after the spin-off with respect to taxes for both pre and post spin-off periods. Under this agreement, ADP is generally required to indemnify the Company for any income taxes attributable to ADP's operations or the Company's operations and for any non-income taxes attributable to ADP's operations, in each case for all pre spin-off periods as well as any taxes arising from transactions effected to consummate the spin-off, and the Company generally is required to indemnify ADP for any non-income taxes attributable to the Company's operations for all pre spin-off periods and for any income taxes attributable to the Company's operations for post spin-off periods. The Company is generally required to indemnify ADP against any tax resulting from the spin-off (and against any claims made against ADP in respect of any tax imposed on its stockholders), in each case if that tax results from (i) an issuance of a significant amount of the Company's equity securities, a redemption of a significant amount of the Company's equity securities or the Company's involvement in other significant acquisitions of the Company's equity securities (excluding the spin-off), (ii) other actions or failures to act by the Company, or (iii) any of the Company's representations or undertakings referred to in the tax matters agreement being incorrect or violated. ADP will generally be required to indemnify the Company for any tax resulting from the spin-off if that tax results from (a) ADP's issuance of its equity securities, redemption of its equity securities, or involvement in other acquisitions of its equity securities, (b) other actions or failures to act by ADP, or (c) any of ADP's representations or undertakings referred to in the tax matters agreement being incorrect or violated. The Company recognized receivables from ADP of $1.8 million and $1.0 million as of September 30, 2017 and June 30, 2017, respectively, and payables to ADP of $1.3 million and $1.2 million as of September 30, 2017 and June 30, 2017, respectively, under the tax matters agreement. In accordance with the tax matters agreement, the Company recognized a net gain of $0.8 million in the three months ended September 30, 2017 in other income, net in the consolidated statement of operations associated with an indemnification receivable from ADP for pre spin-off tax periods. Valuation Allowance The Company had valuation allowances of $31.5 million and $35.1 million as of September 30, 2017 and June 30, 2017 , respectively, because the Company has concluded it is more likely than not that it will be unable to utilize net operating and capital loss carryforwards of certain subsidiaries to offset future taxable earnings. As of each reporting date, the Company’s management considers new evidence, both positive and negative, which could impact management’s view with regard to future realization of deferred tax assets. During the three months ended September 30, 2017 , the valuation allowance balance was decreased by $3.6 million primarily due to the expiration of loss carryforwards. Unrecognized Income Tax Benefits As of September 30, 2017 and June 30, 2017 , the Company had unrecognized income tax benefits of $6.7 million and $6.4 million , respectively, of which $5.1 million and $4.8 million , respectively, would impact the effective tax rate if recognized. During the three months ended September 30, 2017 , the Company increased its unrecognized income tax benefits related to current tax positions by $0.3 million based on information that indicates the extent to which certain tax positions are more likely than not of being sustained. Provision for Income Taxes The effective tax rate for the three months ended September 30, 2017 and 2016 was 30.6% and 29.2% , respectively. The effective tax rate for the three months ended September 30, 2017 and 2016 were favorably impacted by $3.4 million and $5.7 million

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is subject to various claims and litigation 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. There can be no assurance that these matters will be resolved in a manner that is not adverse to the Company. 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. Legal Proceedings From time to time, the Company is involved in legal, regulatory, and arbitration proceedings concerning matters arising in connection with the conduct of its business activities. Such proceedings can be expensive and disruptive to normal business operations. When losses are considered probable and reasonably estimable, the Company records a liability in the amount of its best estimate for the ultimate loss. At this time, the Company is unable to reasonably estimate any reasonably possible loss or ranges of losses on the matters and proceedings described below. Competition Matters The Company is involved in three lawsuits that set forth allegations of anti-competitive agreements between the Company and The Reynolds and Reynolds Company ("Reynolds and Reynolds") relating to the manner in which the defendants control access to, and allow integration with, their respective DMSs. The Company has also received from the Federal Trade Commission ("FTC") a Civil Investigative Demand consisting of a request to produce documents relating to any agreement between the Company and Reynolds and Reynolds. On February 3, 2017, Motor Vehicle Software Corporation (“MVSC”) filed an antitrust suit against the Company, Reynolds and Reynolds, and CVR, in the U.S. District Court for the Central District of California, seeking treble damages and injunctive relief. On May 1, 2017, MVSC filed an amended complaint in connection with the case. On June 15, 2017, the defendants filed motions to dismiss the complaint. Plaintiff’s opposition to those motions was submitted to the court on July 31, 2017, and defendants’ replies were due on August 21, 2017. On October 2, 2017 the court ruled on the motions. In its order, the court dismissed several claims with leave to amend, and allowed the remainder to go forward. On May 1, 2017, Authenticom, Inc. ("Authenticom") filed an antitrust suit against the Company's operating subsidiary, CDK Global, LLC, and Reynolds and Reynolds, in the U.S. District Court for the Western District of Wisconsin, seeking treble damages and injunctive relief. Authenticom moved for a preliminary injunction on May 18, 2017, which the court granted on July 14, 2017, subject to Authenticom’s posting of a $1 million bond. The form of that injunction was handed down by the court on July 28, 2017, and defendants filed notices of appeal on the same day. On August 8, 2017, the U.S. Court of Appeals for the Seventh Circuit granted defendants' motion to stay the injunction pending appeal. Defendants' appellate brief was submitted on August 22, 2017, Authenticom's response on September 5, 2017, and defendants' reply September 12, 2017. Oral argument on that appeal was heard by the Court of Appeals on September 19, 2017. On July 21, 2017, the defendants filed motions to dismiss the complaint in the district court. Plaintiff's opposition was submitted September 8, 2017, and defendants' reply on October 6, 2017. On October 19, 2017, Teterboro Automall, Inc. d/b/a Teterboro Chrysler Dodge Jeep Ram filed a putative class-action antitrust suit against the Company’s operating subsidiary, CDK Global, LLC, and Reynolds and Reynolds, in the U.S. District Court for the District of New Jersey, seeking certification as a class action, treble damages, and injunctive and declaratory relief. The Company believes that these cases are without merit and intends to continue to contest the claims in these cases vigorously. Accordingly, legal and expert fees may be significant, and an adverse result in these suits could have a material adverse effect on the Company's business, results of operations, financial condition, or liquidity. On June 22, 2017, the Company received from the FTC a Civil Investigative Demand consisting of interrogatories and a request to produce documents relating to any agreements between the Company and Reynolds and Reynolds. The Company is responding to the request. The request merely seeks information, and no proceedings have been instituted. The Company believes there has not been any conduct by the Company or its current or former employees that would be actionable under the antitrust laws in connection with the agreements between ourselves and Reynolds and Reynolds. At this time, the Company does not have sufficient information to predict the outcome of, or the cost of responding to or resolving this investigation. Other Proceedings The Company is otherwise involved from time to time in other proceedings not described above. Based on information available at this time, the Company believes that the resolution of these other matters currently pending will not individually or in the aggregate have a material adverse effect on our business, results of operations, financial condition, or liquidity. The Company's view of these matters may change as the proceedings and events related thereto unfold. Other Contingencies The Company has provided approximately $28.1 million of guarantees as of September 30, 2017 in the form of surety bonds issued to support certain licenses and contracts which require a surety bond as a guarantee of performance of contractual obligations. In general, the Company would only be liable for the amount of these guarantees in the event the Company defaulted in performing the obligations under each contract, of which, the probability is remote. The Company had a total of $4.6 million in letters of credit outstanding as of September 30, 2017

Equity [Abstract]
Share Repurchase Transactions	Share Repurchases In January 2017, the Board of Directors authorized the Company to repurchase up to $2.0 billion of our common stock as part of a return of capital plan. Under the authorization, the Company may purchase its common stock in the open market or in privately negotiated transactions from time to time as permitted by federal securities laws and other legal requirements. The actual timing, number, and price of any shares to be repurchased is determined at management's discretion and depends on a number of factors, including the market price of the shares, general market and economic conditions, and other potential uses for free cash flow including, but not limited to, potential acquisitions. In May 2017, the Company entered into an accelerated share repurchase agreement ("May 2017 ASR") to purchase $350.0 million of the Company's common stock. Under the terms of the May 2017 ASR, the Company made a $350.0 million payment in May 2017 and received initial delivery of approximately 4.5 million of the Company's common stock. In September 2017, the Company received an additional 1.1 million shares of common stock in final settlement of the May 2017 ASR, for a total of 5.6 million shares. The value reflected in treasury stock upon completion of the May 2017 ASR represents the value of the shares received based on the closing price of the Company's stock on the respective settlement dates, which is less than the $350.0 million cash paid by $3.1 million . Additionally, the Company made open market repurchases of approximately 0.2 million shares of the Company's common stock during the three months ended September 30, 2017 for a total cost of $14.6 million

Summary of Significant Accoun22

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Sep. 30, 2017
Accounting Policies [Abstract]
Basis of Accounting	The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect assets, liabilities, revenues, and expenses that are reported in the accompanying financial statements and footnotes thereto. Actual results may differ from those estimates and assumptions.
Revenue recognition	The Company recognizes software revenues in accordance with Accounting Standards Codification (“ASC”) 985-605, “Software - Revenue Recognition,” and non-software related revenue, including Software-as-a-Service (“SaaS”), in accordance with ASC 605, "Revenue Recognition" ("ASC 605"). The Company generates revenues from four categories: subscription, digital advertising, transactional services, and other. Taxes collected from customers and remitted to governmental authorities are presented on a net basis; that is, such taxes are excluded from revenues. Subscription. In the Retail Solutions North America (“RSNA”) and CDK International (“CDKI”) segments, CDK provides software and technology solutions for automotive retailers and original equipment manufacturers ("OEMs"), which includes: • Dealer Management Systems (“DMSs”) and layered applications, where the software may be installed onsite at the customer’s location, or hosted and provided on a SaaS basis, including ongoing maintenance and support; • Interrelated services such as installation, initial training, and data updates; • Websites, search marketing, and reputation management services (RSNA only); and • Hardware on a service basis, meaning no specific assets are identified or a substantive right of substitution exists. Revenues for term licenses are recognized ratably over the software license term, as vendor-specific objective evidence of the fair values of the individual elements in the sales arrangement does not exist. Revenue recognition commences at the installation dates, when customer acceptance has occurred, and collectability of a determinable amount is probable. In the case of hosted applications, the customer does not have the contractual right to take possession of the software and the items delivered at the outset of the contract (i.e., installation, training, etc.) do not have value to the customer without the software license and ongoing support and maintenance. Any upfront fees charged in the case of hosted arrangements are recognized ratably over the expected benefit period of the arrangement, typically five years. The unrecognized portion of these revenue elements is recorded as deferred revenue. Advertising services. In the Advertising North America (“ANA”) segment, the Company receives revenues from the placement of internet advertising for automotive retailers and OEMs. Advertising revenues are recognized when the services are rendered. Transaction revenues . In the RSNA segment, the Company receives fees per transaction for providing auto retailers interfaces with third parties to process credit reports, vehicle registrations, and automotive equity mining. Revenue is recognized at the time the services are rendered. Transaction revenues are recorded in revenues gross of costs incurred for credit report processing, vehicle registrations, and automotive equity mining as the Company is contractually responsible for providing the service, software, and/or connectivity to the customers, and therefore, the Company is the primary obligor under ASC 605. Other
Deferred costs	Costs to deliver services are expensed to cost of revenues as incurred with the exception of specific costs directly related to transition or installation activities, including payroll-related costs for the Company's implementation and training teams, as well as commission costs for the sale. These costs are deferred and expensed proportionately over the same period that the deferred revenues are recognized as revenues. Deferred amounts are monitored regularly to ensure appropriate asset and expense recognition. Current deferred costs classified within other current assets on the condensed consolidated balance sheets were $93.2 million and $94.4 million as of September 30, 2017 and June 30, 2017 , respectively. Long-term deferred costs classified within other assets on the condensed consolidated balance sheets were $109.4 million and $115.0 million as of September 30, 2017 and June 30, 2017
Funds receivable and funds held for clients and client fund obligations	Funds receivable and funds held for clients represent amounts received or expected to be received from clients in advance of performing titling and registration services on behalf of those clients. These amounts are classified within other current assets on the condensed consolidated balance sheets. The total amount due to remit for titling and registration obligations with the department of motor vehicles is recorded to client fund obligations which is classified as accrued expenses and other current liabilities on the condensed consolidated balance sheet. Funds receivable was $28.1 million and $25.7 million , and funds held for clients was $7.9 million and $7.9 million as of September 30, 2017 and June 30, 2017 , respectively. Client fund obligation was $36.0 million and $33.6 million as of September 30, 2017 and June 30, 2017
Computer software to be sold, leased, or otherwise marketed	The Company's policy provides for the capitalization of certain costs of computer software to be sold, leased, or otherwise marketed. The Company's policy provides for the capitalization of all software production costs upon reaching technological feasibility for a specific product. Technological feasibility is attained when software products have a completed working model whose consistency with the overall product design has been confirmed by testing. Costs incurred prior to the establishment of technological feasibility are expensed as incurred. The establishment of technological feasibility requires judgment by management and in many instances is only attained a short time prior to the general release of the software. Maintenance-related costs are expensed as incurred. Pursuant to this policy, the Company recognized expenses of $38.0 million and $38.7 million for the three months ended September 30, 2017 and 2016
Fair value of financial instruments	The Company determines the fair value of financial instruments in accordance with accounting standards pertaining to fair value measurements. Such standards define fair value and establish a framework for measuring fair value in accordance with GAAP. Cash and cash equivalents, accounts receivable, other current assets, accounts payable, and other current liabilities are reflected in the condensed consolidated balance sheets at cost, which approximates fair value due to the short-term nature of these instruments. The carrying value of the Company's term loan facilities (as described in Note 8), including accrued interest, approximates fair value based on the Company's current estimated incremental borrowing rate for similar types of arrangements. The approximate aggregate fair value of the Company's senior notes as of September 30, 2017 was $1,412.4 million based on quoted market prices for the same or similar instruments and the carrying value was $1,350.0 million
Recently Issued Accounting Pronouncement	Recently Issued Accounting Pronouncements In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other.” ASU 2017-04 simplifies the accounting for goodwill impairment by eliminating Step 2 of the current goodwill impairment test, which required a hypothetical purchase price allocation. Goodwill impairment will now be the amount by which the reporting unit’s carrying value exceeds its fair value, limited to the carrying value of the goodwill. ASU 2017-04 is effective for financial statements issued for fiscal years, and interim periods beginning after December 15, 2019. The adoption of ASU 2017-04 is not expected to have a material impact on the Company's consolidated results of operations, financial condition, or cash flows. In November 2016, the FASB issued ASU 2016-18, “Restricted Cash.” ASU 2016-18 clarifies cash flow presentation for restricted cash. ASU 2016-18 is effective for financial statements issued for fiscal years, and interim periods beginning after December 15, 2017. The adoption of ASU 2016-18 will not have a material impact on the Company's consolidated statements of cash flows. In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments (Topic 230).” ASU 2016-15 addresses eight specific cash flow issues where there is diversity in practice in how these certain cash receipts and cash payments are presented and classified in the statements of cash flows. ASU 2016-15 is effective for financial statements issued for fiscal years, and interim periods beginning after December 15, 2017. The adoption of ASU 2016-15 will not have a material impact on the Company's consolidated statements of cash flows. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires that lessees recognize right-of-use assets and lease liabilities for any lease classified as either a finance or operating lease that is not considered short-term. The accounting applied by lessors is largely consistent with the existing lease standard. ASU 2016-02 is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2018. The Company has obligations under lease agreements for facilities and equipment, which are classified as operating leases under the existing lease standard. While the Company is still evaluating the impact that ASU 2016-02 will have on the consolidated results of operations, financial condition, or cash flows, the Company's financial statements will reflect an increase in both assets and liabilities due to the requirement to recognize right-of-use assets and lease liabilities on the consolidated balance sheets for its facility and equipment leases. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 requires an entity to recognize revenue depicting the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will also result in enhanced revenue related disclosures. The guidance permits two methods of adoption: 1) retrospectively to each prior reporting period presented (full retrospective), or 2) retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective). In July 2015, the FASB deferred the effective date of ASU 2014-09 by one year and subsequently issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date." As a result, the standard and subsequent amendments thereto, will be effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2017. In fiscal 2017, the Company established a cross-functional implementation team to evaluate the impact of the new standard on its revenue contracts including reviewing current accounting policies, evaluating new disclosure requirements, identifying appropriate changes to business processes, information technology systems, and internal controls to support revenue recognition, and disclosure under the new guidance. The Company has made significant progress in its qualitative assessment of the impact of the new revenue recognition standard; however, efforts to quantify the impact upon adoption remain ongoing. The Company has concluded that it will adopt this standard on a modified retrospective basis, which will result in a cumulative effect adjustment to retained earnings when the standard is adopted on July 1, 2018. While the Company continues to evaluate the impact of ASU 2014-09, and related ASUs, on its consolidated results of operations, financial condition, or cash flows, the following determinations have been made: • Under the current accounting guidance for software, ASC 985-605, revenues for onsite licenses are recognized ratably over the software license term, as CDK lacks vendor-specific objective evidence of the fair values of the individual elements of the sales arrangement; however, upon adoption of ASC 606 revenues may be recognized upon installation of onsite software based on estimated standalone selling price at the time of the sale. This will result in a cumulative adjustment (an increase) to beginning retained earnings, for which management is completing its evaluation and quantifying the impact. • Aside from revenues for onsite software licenses discussed above, the Company currently accounts for the majority of its revenues, including SaaS and other service arrangements under ASC 605. Under both the existing revenue standard, ASC 605, and the new standard pending adoption, ASC 606, the revenue for ongoing services will be recognized ratably over the term of arrangement; however, management is currently evaluating the impact of other aspects of the standard, including variable consideration. •
