Gentlemen:

This letter (this “ Agreement ”) constitutes the agreement between CDK Global, Inc., a Delaware corporation (the “ Company ”), Elliott Associates, L.P., a Delaware limited partnership (“ Elliott Associates ”), Elliott International, L.P., a Cayman Islands limited partnership (“ Elliott International ”), and Elliott International Capital Advisors Inc., a Delaware corporation (together with Elliott Associates and Elliot International, the “ Investors ”), with respect to the matters set forth below. Capitalized terms used herein and not otherwise defined have the meanings ascribed to them in paragraph 12 below.  

1. New Directors . The Company shall promptly appoint two (2) individuals (each a “ New Director ” and together the “ New Directors ”) to the board of directors of the Company (the “ Board ”) identified from the Candidate List (as defined below); provided the first of the New Directors shall be identified no later than September 6, 2016 and the second of the New Directors shall be identified no later than October 6, 2016. The “ Candidate List ” includes the individuals submitted to the Company by the Investors concurrently with the execution of this Agreement. Subject to the approval by the Investors (such approval not to be unreasonably withheld), the Company may add to the Candidate List one (1) individual with similar qualifications to the other individuals on the Candidate List. Promptly following identification of each of the New Directors, but no later than five (5) business days thereafter, the Board shall take such action necessary to increase the size of the Board by one (1) and appoint such New Director to fill the vacancy so created, such that the size of the Board shall be nine (9) directors following the appointment of the first of the New Directors and ten (10) directors following the appointment of the second of the New Directors. Each of the New Directors shall serve as a director until a successor is duly elected and qualified or until the New Director’s earlier death, resignation, disqualification or removal, subject to the terms of this Agreement. The size of the Board shall not exceed ten (10) directors at any time prior to the Expiration Date. The Board also shall appoint each of the New Directors to an appropriate committee of the Board at such time consistent with the Board’s normal course of operations, but no later than one hundred and fifty (150) days after the appointment of such New Director to the Board.

2. New Director Agreements, Arrangements and Understandings . Each of the Investors agrees that neither it nor any of its Affiliates (a) will pay any compensation to any New Director (including replacement candidates contemplated by paragraph 3) regarding such Person’s service on the Board or any committee thereof or (b) will have any agreement, arrangement or understanding, written or oral, with any New Director (including replacement candidates contemplated by paragraph 3) regarding such Person’s service on the Board or any committee thereof (including without limitation pursuant to which such Person will be compensated for his or her service as a director on, or nominee for election to, the Board or any committee thereof). The Company agrees and acknowledges that the payment by the Investors of compensation to the New Directors on or prior to the date of this Agreement for providing information to the Investors in connection with their potential service on the Board shall not be deemed a violation of this paragraph 2.

3. 2016 Annual Meeting; Replacements . The Company shall include the New Directors on its slate for election as directors of the Company at its 2016 Annual Meeting of Stockholders (the “ 2016 Annual Meeting ”). If a New Director resigns, refuses, or is unable to serve as a director at any time prior to the Expiration Date, the Company and the Investors shall mutually agree on a replacement who is Independent and satisfies the Board membership criteria set forth in the Company’s Corporate Governance Guidelines. Such replacement for the New Director shall be appointed to the Board to serve the unexpired term of the departed New Director, and shall be considered a New Director for all purposes of this Agreement. Any other vacancies on the Board or any committee thereof created prior to the Expiration Date shall be filled by the Board upon the recommendation of the Nominating and Governance Committee. The Investors’ right to participate in the selection of a replacement candidate, and the Company’s obligation to appoint such candidate to the Board, in accordance with this paragraph 3, shall terminate prior to the Expiration Date at such time as the Investors’ aggregate beneficial ownership decreases to less than 3.0% of the Company’s common shares as a result of dispositions by the Investors.

4. New Director Information . As a condition to a New Director’s appointment to the Board and any subsequent nomination for election as a director at the Company’s Annual Meeting of Stockholders, the New Directors will provide any information the Company reasonably requires, including information required to be disclosed in a proxy statement or other filing under applicable law, stock exchange rules or listing standards, information in connection with assessing eligibility, independence and other criteria applicable to directors or satisfying compliance and legal obligations, and will consent to appropriate background checks, to the extent, in each case, consistent with the information and background checks required by the Company in accordance with past practice with respect to other members of the Board. If, following the completion of the Company’s initial background review process, the Board learns that a New Director has committed, been indicted or charged with, or made a plea of nolo contendre to a felony or a misdemeanor involving moral turpitude, deceit, dishonesty or fraud, then the Board may request that the New Director submit his or her resignation and, in such case, the Nominating and Governance Committee of the Board, together with the Investors, will identify a mutually agreeable replacement; provided, that the Investors aggregate beneficial ownership of the Company’s common shares is 3.0% or more.

5. Company Recommendations at 2016 Annual Meeting . In connection with the 2016 Annual Meeting (and any adjournments or postponements thereof), the Company will recommend that the Company’s stockholders vote in favor of the election of each of the Board’s nominees (including the New Directors), solicit proxies for each of the Board’s nominees, and cause all Company common stock represented by proxies granted to it (or any of its officers, directors or representatives) to be voted in favor of each of the Board’s nominees.

6. Voting of Investors’ Shares . In connection with the 2016 Annual Meeting (and any adjournments or postponements thereof), so long as both New Directors have been nominated by the Board for re-election as a director the Investors will cause to be present for quorum purposes and vote or cause to be voted all Company common stock beneficially owned by them or their controlling or controlled Affiliates and which they or such controlling or controlled Affiliates are entitled to vote on the record date for the 2016 Annual Meeting in favor of (a) the election of each of the Board’s nominees (including the New Directors) and (b) otherwise in accordance with the Board’s recommendation on any proposal not related to an Extraordinary Transaction.

7. Company Policies . The parties hereto acknowledge that each of the New Directors, upon election to the Board, will serve as a member of the Board and will be governed by the same protections and obligations regarding confidentiality, conflicts of interest, related party transactions, fiduciary duties, codes of conduct, trading and disclosure policies, director resignation policy, and other governance guidelines and policies of the Company as other directors (collectively, “ Company Policies ”), and shall have the same rights and benefits, including with respect to insurance, indemnification, compensation and fees, as are applicable to all independent directors of the Company. The Company represents and warrants that: (i) all Company Policies currently in effect are publicly available on the Company’s website or described in its proxy statement filed with the Securities and Exchange Commission (the “ SEC ”) on September 22, 2015 or have otherwise been provided to the Investors, and such Company Policies will not be amended prior to the appointment of the New Directors other than as may be required to implement this Agreement and (ii) prior to the Expiration Date, any changes to the Company Policies, or new Company Policies, will be adopted in good faith and not for the purpose of undermining or conflicting with the arrangements contemplated hereby.   Notwithstanding the foregoing, no Company Policies, as currently in effect or as may be amended or adopted, shall in any way inhibit any Board members (including the New Directors) from engaging in dialogue with the Investors so long as they comply with their confidentiality obligations in their capacity as Board members.

Exhibit A

Press Release 

CDK Global to Add Two Independent Directors to Board

Reaches Agreement with Elliott Management

HOFFMAN ESTATES, IL, August 3, 2016 – CDK Global, Inc. (Nasdaq:CDK) announced today that it will add two independent directors to its Board under an agreement with Elliott Management, one of CDK’s largest shareholders with an approximately 9.3% ownership stake. Under the terms of the agreement, CDK’s Board of Directors will appoint two independent directors identified by Elliott, and Elliott has agreed to certain “standstill” provisions. The addition of the two directors will expand CDK’s Board to 10 members, all of whom will stand for re-election at the 2016 Annual Meeting of Stockholders.

Leslie Brun, non-executive chairman of CDK Global, said, “With the appointment of Robert Tarkoff to the Board in June, and the addition of two additional independent directors, CDK will have added significant expertise to our Board. We look forward to the new perspectives they will bring as we build on CDK’s positive momentum and improved operations.”

Brian MacDonald, chief executive officer of CDK Global, said, “We look forward to working with the new directors as we continue to fundamentally realign our business to better serve customers and deliver value to shareholders. We are already making excellent progress and are well on our way to achieving our goal of improving adjusted EBITDA margins by 1,300 basis points to 35% by June 2018. In addition, we have today announced in our full-year earnings release that we expect to exit fiscal year 2019 with an adjusted EBITDA margin of 40% or above.

“As we move forward, we are also committed to an active and ongoing capital allocation review. We have already significantly accelerated the pace of capital return with our recent commitment to return $1 billion by the end of calendar year 2016 – a year earlier than our prior target. At the conclusion of our current capital return program, we will evaluate our capital allocation policy, which will likely result in additional share repurchases, as well as continued dividend distributions,” concluded MacDonald.

Jesse Cohn, Senior Portfolio Manager at Elliott, commented, "We have had the opportunity to spend significant time with CDK’s management and the Board to understand the cost transformation plan and the mechanisms in place to ensure its achievement. We are pleased with the steps taken to date, and we think that Brian and his team have laid out a strategy not only to achieve their plan, but to surpass it. Elliott fully supports CDK’s Board and management, and we believe the expanded Board will have the right expertise to oversee the execution of the plan and the achievement of its targets. CDK possesses tremendous value as the unquestioned leader in a highly attractive industry. We believe that the planned cost and business realignment will improve the Company’s profitability, growth profile and ability to deploy capital. We expect these steps to deliver meaningful value to CDK’s customers and shareholders.”

Morgan Stanley is acting as financial advisor to CDK, and Weil, Gotshal & Manges LLP is acting as legal advisor.

Exhibit B

Company Guidance

CDK Global Reports Strong Fiscal 2016 Results; Provides Fiscal 2017 Guidance along with 2018 and 2019 Targets

Robust Fourth Quarter Provides Solid Momentum into Fiscal 2017

HOFFMAN ESTATES, Ill., Aug. 03, 2016 (GLOBE NEWSWIRE) -- CDK Global, Inc. (Nasdaq:CDK) today announced its fiscal 2016 financial results, its earnings outlook for fiscal 2017, and financial targets for fiscal 2018 and 2019.

Highlights

Fiscal year

• Fiscal 2016 GAAP net earnings attributable to CDK margin expansion of 270 bps to 11.3%; adjusted EBITDA margin expansion of 370 bps to 26.6%
• Fiscal 2016 growth in GAAP diluted net earnings attributable to CDK per share of 37% to $1.51 per share; growth in adjusted diluted net earnings attributable to CDK per share of 34% to $1.74 per share

Fourth quarter

• Fiscal 2016 GAAP net earnings attributable to CDK margin expansion of 270 bps to 10.8%; adjusted EBITDA margin expansion of 630 bps to 28.4%
• Fiscal 2016 growth in GAAP diluted net earnings attributable to CDK per share of 48% to $0.37 per share; growth in adjusted diluted net earnings attributable to CDK per share of 75% to $0.49 per share

Fiscal 2017 guidance, fiscal 2018 and 2019 targets

• Fiscal 2017 GAAP net earnings attributable to CDK margin expansion of 200-250 bps and adjusted EBITDA margin expansion of 500-550 bps
• Fiscal 2017 GAAP net earnings attributable to CDK exit margin of approximately 13% and adjusted EBITDA exit margin of approximately 33%
• Fiscal 2018 targets of revenue growth of approximately 5% from fiscal 2017, adjusted EBITDA dollar growth of 44-48% from fiscal 2016, adjusted EBITDA margin of 35% and adjusted EBITDA exit margin of 36-38%
• Fiscal 2019 target of adjusted EBITDA exit margin of 40% or above

“I am pleased to announce that CDK delivered an exceptionally strong quarter and fiscal year,” said Brian MacDonald, chief executive officer. “We achieved a record number of customer renewals in the fourth quarter, we signed a top 10 dealer group, and we executed a comprehensive reorganization, to name a few. We’ve made significant improvements to our business that are benefitting both our customers and employees, while continuing to grow our business and delivering value to shareholders. We’re forecasting 500-550 bps of adjusted EBITDA margin expansion in fiscal 2017 which, combined with the 370 bps of expansion achieved in fiscal 2016, puts us on track to achieve our transformation target of approximately 1,300 bps of expansion through fiscal 2018.”

“We accelerated the pace of capital return to shareholders with our recent commitment to return $1 billion to shareholders by December 2016.  Since the original announcement in December 2015, we have returned $613 million of the $1 billion to shareholders through the $250 million December ASR, a $300 million ASR entered into in June, and $63 million in dividends,” said Al Nietzel, chief financial officer. “At the conclusion of this commitment, we will evaluate our policy to determine the appropriate next step for returning capital to our shareholders.”

Please refer to the tables at the end of this release for a reconciliation of the GAAP results to the non-GAAP results, which we refer to as our adjusted results throughout the body of this press release. Results below reflect year over year comparisons.

Total Company

Impacts to the Fiscal Year:

• Foreign exchange rates: Growth in adjusted revenues and earnings before income taxes were negatively impacted by 2 and 3 percentage points, respectively, from unfavorable foreign exchange rates.
• CEO transition: On a GAAP basis, transition costs reduced growth in both earnings before income taxes and net earnings attributable to CDK 3 percentage points, and reduced pretax margin expansion 40 basis points.  On an adjusted basis, transition costs reduced growth in both earnings before income taxes and net earnings almost 3 percentage points, and reduced pretax, net earnings attributable to CDK and EBITDA margin expansion 40, 30 and 20 basis points, respectively.
• Tax rate: The GAAP effective tax rate of 33.1% benefited from the domestic production activities deduction and certain pre spin-off related indemnification adjustments, partially offset by tax charges associated with the repatriation of foreign cash and a valuation allowance adjustment. The adjusted effective tax rate of 33.8%, which excludes the impact of certain pre spin-off indemnification adjustments, was lower than the anticipated range of 34.0% to 34.5% primarily due to a fourth quarter change in estimate of the tax associated with the repatriation of foreign cash and other foreign adjustments.

Impacts to the Fourth Quarter:

• Foreign exchange rates: Growth in adjusted revenues and earnings before income taxes were both negatively impacted by 1 percentage point from unfavorable foreign exchange rates.
• Tax rate: The GAAP effective tax rate of 31.5% benefited from a reduced tax cost on repatriation of foreign cash, partially offset by a tax charge associated with a valuation allowance adjustment. The adjusted effective tax rate of 33.1% was lower than anticipated primarily due to a fourth quarter change in estimate of the tax associated with the repatriation of foreign cash and other foreign adjustments.

• GAAP and adjusted pretax margin expansion for the fourth quarter and fiscal year were primarily due to operating efficiencies associated with the business transformation plan resulting in lower labor-related costs, and scale from increased revenues.
  
  

• On an adjusted constant currency basis, revenues increased 11% for the fourth quarter and 6% for the fiscal year.
• On an adjusted constant currency basis, earnings before income taxes increased 131% for the fourth quarter and 39% for the fiscal year.
• GAAP and adjusted pretax margin expansion for the fourth quarter and fiscal year were primarily due to scale from increased revenues, operating efficiencies associated with the business transformation plan, and accrual true-ups in last year’s fourth quarter.
  
  

• GAAP and adjusted pretax margin expansion for the fourth quarter and fiscal year were primarily due to a higher mix of higher margin network advertising revenues and increased operating efficiencies associated with the business transformation plan, partially offset by favorable timing of items in fiscal 2015.
  
  

The fiscal 2017 forecast includes $85-95 million of incremental adjusted EBITDA attributable to the execution of our business transformation plan.

Tax Rate

CDK's anticipated GAAP effective tax rate for fiscal 2017 is 32.5-33.0% compared to 33.1% for fiscal 2016. The anticipated adjusted effective tax rate for fiscal 2017 is 33.0-33.5% compared to 33.8% for fiscal 2016. These anticipated tax rates include forecasted tax benefits associated with the planned adoption of a new stock compensation accounting standard on July 1, 2016. Excess tax benefits and tax deficiencies related to the adoption of this standard will impact the provision for income taxes, resulting in increased volatility in our effective tax rates.

Please refer to the tables at the end of this release for a reconciliation of the GAAP forecast to the adjusted forecast.

Fiscal 2018 and 2019 targets

Current targets are as follows:

• Fiscal 2018 revenue growth of approximately 5% from fiscal 2017
• Fiscal 2018 adjusted EBITDA dollar growth of 44-48% from the adjusted $562.1 million in fiscal 2016
• Fiscal 2018 adjusted EBITDA margin of 35%
• Fiscal 2018 adjusted EBITDA exit margin of 36-38%
• Fiscal 2019 adjusted EBITDA exit margin of 40% or above

Fiscal 2018 and 2019 targets represent financial objectives distinct from forecasts of performance. Therefore, CDK has not provided reconciliations of its fiscal 2018 and 2019 adjusted EBITDA targets to the most directly comparable GAAP measure of net earnings attributable to CDK, because projecting potential adjustments to GAAP results for fiscal 2018 and 2019 targets is not feasible and could be misleading to users of this financial information. The accompanying reconciliations of the fiscal 2017 forecasted adjusted measures with the most directly comparable GAAP measures are indicative of the reconciliations that will be prepared for the same fiscal 2018 and 2019 adjusted targets in the future.

CDK Global, Inc.
Segment Financial Data
(In millions)
(Unaudited)

During fiscal 2016, the Company began to report segment revenues and earnings before income taxes using actual foreign exchange rates. Previously, the Company's revenues and earnings before income taxes for each segment were adjusted to reflect budgeted foreign exchange rates, which resulted in reconciling items for foreign exchange so as to present segment results on a consistent basis without the impact of fluctuations in foreign currency exchange rates. Segment information for fiscal 2015 has been updated to conform to the new presentation and the effect of foreign exchange now resides within reportable segment revenues and earnings before income taxes.

(a) The table below presents a reconciliation of revenues to constant currency adjusted revenues and earnings before income taxes to constant currency adjusted earnings before income taxes for the Automotive Retail North America (ARNA) segment.

(b) The table below presents a reconciliation of revenues to constant currency revenues and earnings before income taxes to constant currency earnings before income taxes for the Automotive Retail International (ARI) segment.

(c) The table below presents a reconciliation of revenues to constant currency revenues and earnings before income taxes to constant currency adjusted earnings before income taxes for the Digital Marketing (DM) segment.

(d) The table below presents a reconciliation of loss before income taxes to constant currency adjusted loss before income taxes for the Other segment.

(e) Refer to the Non-GAAP Financial Measures section of this earnings release for additional information on our non-GAAP adjustments.

(a) Refer to the Non-GAAP Financial Measures section of this earnings release for additional information on our non-GAAP adjustments.

(b) The weighted-average common shares outstanding for fiscal 2016 reflect a reduction of 1.0 million shares that were inadvertently issued and distributed at the spin-off to ADP with respect to certain unvested ADP equity awards. For additional information on this matter, refer to Note 1, "Basis of Presentation" in our unaudited condensed consolidated and combined financial statements for the quarterly period ended September 30, 2015 filed on Form 10-Q.

(a) The point estimates are arbitrary amounts within the guidance ranges provided and are not meant to represent CDK’s forecast of actual results. They are used solely to provide a means to reconcile each non-GAAP guidance range to the most directly comparable GAAP measure in dollars and percentages, where applicable.

(b) Refer to the Non-GAAP Financial Measures section of this earnings release for additional information on our non-GAAP adjustments.

(a) Average revenue per dealer management system (DMS) customer site and average revenue per website have been updated for fiscal 2015 to reflect budgeted foreign exchange rates for fiscal 2016.

(b) DMS Customer Sites - We track the number of customer sites that have an active DMS. Consistent with our strategy of growing our automotive retail customer base, we view the number of customer sites purchasing our DMS solutions as an indicator of market penetration for our Automotive Retail segments. Our DMS customer site count includes retailers with an active DMS that sell vehicles in the automotive and adjacent markets. Adjacent markets include heavy truck dealerships that provide vehicles to the over-the-road trucking industry; recreation dealerships in the motorcycle, marine and recreational vehicle industries; and heavy equipment dealerships in the agriculture and construction equipment industries. We consider a DMS to be active if we have billed a subscription fee for that solution during the most recently ended calendar month.

(c)  Average Revenue Per DMS Customer Site - Average revenue per Automotive Retail DMS customer site is an indicator of the adoption of our solutions by DMS customers, and we monitor changes in this metric to measure the effectiveness of our strategy to deepen our relationships with our current customer base through upgrading and expanding solutions. We calculate average revenue per DMS customer site by dividing the monthly applicable revenue generated from our solutions in a period by the average number of DMS client sites in the period. Revenue underlying this metric is based on budgeted foreign exchange rates.

(d) Websites - For the Digital Marketing segment, we track the number of websites that we host and develop for our OEM and automotive retail customers as an indicator of business activity. The number of websites as of a specified date is the total number of full function dealer websites or portals that are currently accessible.

(e) Average Revenue Per Website - We monitor changes in our average revenue per website as an indicator of the relative depth of our relationships in our Digital Marketing segment. We calculate average revenue per website by dividing the monthly revenue generated from our Digital Marketing solutions in a period, excluding OEM advertising revenues, by the average number of customer websites in the period. Revenue underlying this metric is based on budgeted foreign exchange rates.

Non-GAAP Financial Measures

We use certain adjusted results to evaluate our operating performance. In addition, we use adjusted EBITDA, among other measures, as an input to determine incentive-based compensation. Our non-GAAP adjustments principally relate to expenses and benefits that impact comparability of the underlying GAAP measures. We believe our non-GAAP measures provide relevant and useful information for users of the financial statements because they provide insight into our ongoing operating results. Adjusted revenues, adjusted earnings before income taxes, adjusted provision for income taxes, adjusted net earnings attributable to CDK, adjusted basic and diluted earnings attributable to CDK per share, adjusted EBITDA, and free cash flow reflect the adjustments enumerated below. Because adjusted results are not measures of performance that are calculated in accordance with GAAP, they should not be considered in isolation from, or as a substitute for, other metrics that are calculated in accordance with GAAP.

Management has excluded revenues related to the internet sales leads business, which was part of the ARNA segment and was sold on May 21, 2015, from adjusted revenues.

Management has excluded the following items from adjusted earnings before income taxes:

• Earnings before income taxes related to the internet sales leads business, which was part of the ARNA segment and was sold on May 21, 2015.
  
• Incremental costs incurred for fiscal 2015 that were directly attributable to the spin-off from ADP.
  
• Accelerated amortization recognized in the second quarter of fiscal 2015 in the DM segment for the Cobalt trademark related to the change in useful life.
  
• Incremental costs associated with the formation of corporate departments as a stand-alone public company, incremental stock-based compensation expenses incurred for staff additions to build out corporate functions and director compensation costs, and interest expense related to indebtedness incurred with the spin-off. These costs were incurred in fiscal 2016 and have been reflected as adjustments in fiscal 2015 to present these periods on a comparable basis.
  
• Elimination of the royalty paid to ADP for the utilization of the ADP trademark during fiscal 2015, prior to our spin-off from ADP, as there is no comparable royalty after the spin-off.
  
• Restructuring expenses recognized in connection with our business transformation plan for fiscal 2016 and 2015. Other business transformation expenses are included within cost of revenues and selling, general and administrative expenses and were incurred in connection with our business transformation plan for fiscal 2016 and 2015.
  
• Net (gain)/loss recorded within other income, net associated with an indemnification receivable from ADP or liability to ADP for pre spin-off tax periods in accordance with the tax matters agreement.
  

Management has excluded the following items from adjusted provision for income taxes:

• Income tax effect of pre-tax adjustments described above, including separation costs for fiscal 2015, which were partially tax deductible, and the tax effect of the Internet sales leads business.
  
• Adjustment recognized during fiscal 2015 to deferred taxes related to the bonus depreciation to which ADP is entitled under the tax law and in accordance with the tax matters agreement to claim additional tax depreciation for assets associated with our business for tax periods prior to our spin-off from ADP.
  
• Net income tax benefit to adjust the liability for pre spin-off tax returns related to the tax matters indemnification gain in fiscal 2016. Net income tax expense recognized as a result of filing the pre spin-off tax returns related to the loss in fiscal 2015.
  

Management has excluded the items described above for adjusted earnings before income taxes and adjusted provision for income taxes from adjusted net earnings attributable to CDK and adjusted basic and diluted net earnings attributable to CDK per share.

Management has adjusted the following items from net earnings attributable to CDK in order to calculate adjusted EBITDA:

• Net earnings attributable to noncontrolling interest within the financial statements for the periods presented.
  
• Provision for income taxes within the financial statements for the periods presented.
  
• Interest expense included within the financial statements for the periods presented.
  
• Depreciation and amortization included within the financial statements for the periods presented, including the accelerated amortization attributable to the Cobalt trademark recognized during fiscal 2015.
  
• Incremental costs incurred for fiscal 2015 that were directly attributable to the spin-off from ADP.
  
• Incremental costs associated with the formation of corporate departments as a stand-alone public company and incremental stock-based compensation expenses incurred for staff additions to build out corporate functions and director compensation costs. These costs were incurred in fiscal 2016 and have been reflected as adjustments in fiscal 2015 to present these periods on a comparable basis.
  
• Elimination of the royalty paid to ADP for the utilization of the ADP trademark during fiscal 2015, prior to our spin-off from ADP, as there is no comparable royalty after the spin-off.
  
• Total stock-based compensation expense recognized for the periods presented.
  
• Restructuring expenses recognized in connection with our business transformation plan for fiscal 2016 and 2015. Other business transformation expenses are included within cost of revenues and selling, general and administrative expenses and were incurred in connection with our business transformation plan for fiscal 2016 and 2015. Other business transformation expenses exclude $3.5 million and $4.9 million of accelerated depreciation expense and stock-based compensation expense for the three months ended and full year ended June 30, 2016, respectively, for purposes of calculating adjusted EBITDA.
  
• Net (gain)/loss recorded within other income, net associated with an indemnification receivable from ADP or liability to ADP for pre spin-off tax periods in accordance with the tax matters agreement.
  
• Earnings before income taxes related to the internet sales leads business, which was part of the ARNA segment and was sold on May 21, 2015. Earnings before income taxes related to the Internet sales leads business includes the loss recognized on the sale of $0.8 million in fiscal 2015.
  

Free cash flow is defined as cash flows from operating activities less amounts paid for capital expenditures and capitalized software.

We review certain non-GAAP measures, namely adjusted revenues and adjusted earnings before income taxes, on a constant currency basis to understand underlying business trends. To present these results on a constant currency basis, current period results for entities reporting in currencies other than the U.S. dollar are translated into U.S. dollar using the average monthly exchange rate for the comparable prior period. As a result, constant currency results neutralize the effects of foreign currency.

Forward-looking non-GAAP measures reflect expected adjustments for restructuring expenses, other business transformation expenses, and the related tax effect. In calculating adjusted EBITDA, we also remove total stock-based compensation expense.
