Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: These condensed consolidated financial statements have been prepared by Acxiom Corporation (“Registrant,” “Acxiom,” we, us or the “Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of the Registrant’s management, all adjustments necessary for a fair presentation of the results for the periods included have been made, and the disclosures are adequate to make the information presented not misleading. All such adjustments are of a normal recurring nature. Certain note information has been omitted because it has not changed significantly from that reflected in Notes 1 through 18 of the Notes to Consolidated Financial Statements filed as part of Item 8 of the Registrant’s annual report on Form 10-K for the fiscal year ended March 31, 2018 (“2018 Annual Report”), as filed with the SEC on May 25, 2018. This quarterly report and the accompanying condensed consolidated financial statements should be read in connection with the 2018 Annual Report. The financial information contained in this quarterly report is not necessarily indicative of the results to be expected for any other period or for the full fiscal year ending March 31, 2019. Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”). Actual results could differ from those estimates. Certain of the accounting policies used in the preparation of these condensed consolidated financial statements are complex and require management to make judgments and/or significant estimates regarding amounts reported or disclosed in these financial statements. Additionally, the application of certain of these accounting policies is governed by complex accounting principles and their interpretation. A discussion of the Company’s significant accounting principles and their application is included in Note 1 of the Notes to Consolidated Financial Statements and in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the Company’s 2018 Annual Report. Accounting Pronouncements Adopted During the Current Year In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) and issued subsequent amendments to the initial guidance in August 2015, March 2016, April 2016, May 2016 and December 2016 within ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, respectively. Topic 606 supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of the new guidance is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We adopted Topic 606 as of April 1, 2018 using the modified retrospective method. See Note 2 for further details. In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 719): Scope of Modification Accounting" ("ASU 2017-09"). ASU 2017-09 clarifies when changes to the terms or conditions of a stock-based payment award must be accounted for as modifications. ASU 2017-09 will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a stock-based payment award if the award's fair value, vesting conditions and classification as an equity or liability instrument are the same immediately before and after the change. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. ASU 2017-09 is effective for the Company beginning in fiscal 2019. We adopted the standard in the current fiscal quarter, and adoption of this guidance did not have a material impact on our condensed financial statements and related disclosures. Recent Accounting Pronouncements Not Yet Adopted In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" ("ASU 2017-04"), which eliminates step two from the goodwill impairment test. Under ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for annual periods beginning after December 15, 2019 (fiscal 2021 for the Company), including interim periods within those fiscal years; earlier adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of this guidance to have a material impact on its condensed financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" ("ASU 2016-02"), as a comprehensive new standard that amends various aspects of existing guidance for leases and requires additional disclosures about leasing arrangements. The new standard will require lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases except short-term leases. For lessees, leases will continue to be classified as either operating or financing in the income statement. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model. Lessors will continue to classify leases as operating, direct financing or sales-type leases. Subsequently, the FASB has issued various ASU's to provide further clarification around aspects of Topic 842. ASU 2016-02 is effective for annual periods beginning after December 15, 2018 (fiscal 2020 for the Company), including interim periods within those fiscal years, with early adoption permitted. We will adopt the new standard on April 1, 2019 using the modified retrospective approach. The Company is continuing to evaluate the impact of the adoption of this guidance on its condensed consolidated financial statements and related disclosures. The Company does not anticipate that the adoption of any other recent accounting pronouncements will have a material impact on the Company's consolidated financial position, results of operations or cash flows.

Revenue from Contract with Customer [Abstract]

Topic 606 Adoption Impact and Revenue from Contracts with Customers

TOPIC 606 ADOPTION IMPACT AND REVENUE FROM CONTRACTS WITH CUSTOMERS:

On April 1, 2018, we adopted Topic 606 using the modified retrospective method applied to those contracts which were not completed as of April 1, 2018. Results for reporting periods beginning after April 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic reporting under Topic 605.

Under Topic 606, revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company enters into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. The Company determines revenue recognition through the following steps:


•	Identification of the contract, or contracts, with a customer


•	Identification of the performance obligations in the contract


•	Determination of the transaction price


•	Allocation of the transaction price to the performance obligations in the contract


•	Recognition of revenue when, or as, the Company satisfies a performance obligation

We recorded a net increase to our opening retained earnings of $12.7 million, net of tax, due to the cumulative impact of adopting Topic 606, with the impact primarily related to the capitalization of costs of obtaining customer contracts.

The details of the significant changes and quantitative impact of the changes are disclosed below.

Costs of Obtaining Customer Contracts

The Company previously recognized commission payments made for obtaining a contract as an operating expense when incurred. Under Topic 606, the Company capitalizes incremental costs to acquire contracts and amortizes them over the expected period of benefit, which we have determined as a range of two to five years. As of June 30, 2018, the remaining unamortized contract costs were $18.1 million and are included in deferred commissions, net, in the condensed consolidated balance sheet. Net capitalized costs of $2.9 million were recorded as a reduction to operating expense for the three months ended June 30, 2018. No impairment was recognized for the three months ended June 30, 2018.

Contingent Revenue

The Company previously limited revenue recognition to the amount that was not contingent on the provision of future services. This was typically from fees paid over the contract term for services delivered at the beginning of the contract term.

SEGMENT INFORMATION:

Segment Reporting [Abstract]

SEGMENT INFORMATION:

The Company reports segment information consistent with the way management internally disaggregates its operations to assess performance and to allocate resources.

During the first quarter of fiscal 2019, the Company realigned its portfolio into two distinct business segments: LiveRamp, the identity infrastructure for powering exceptional customer experiences, and Acxiom Marketing Solutions, the leading provider of services for creating a unified approach to data-driven marketing. This realignment allows Acxiom to best meet client needs in a rapidly evolving marketplace, create a strong foundation for continued growth and enhance value for shareholders.

This structure configured Acxiom’s three previous segments into two, aligning key Audience Solutions’ assets to each. All identity assets including IdentityLink, AbiliTec® intellectual property and Acxiom’s TV integrations were consolidated under LiveRamp. The remaining Audience Solutions’ lines of business for data and data services were combined with Marketing Services to create Acxiom Marketing Solutions.

As a result of this organizational realignment, information that our chief operating decision maker regularly reviews for purposes of allocating resources and assessing performance changed.

Revenues and cost of revenue are generally directly attributed to the segments. Certain revenue contracts are allocated among the segments based on the relative value of the underlying products and services. Cost of revenue, excluding non-cash stock compensation expense and purchased intangible asset amortization, is directly charged in most cases and allocated in certain cases based upon proportional usage.

Operating expenses, excluding non-cash stock compensation expense and purchased intangible asset amortization, are attributed to the segment groups as follows:


•	Research and development expenses are primarily directly recorded to each segment group based on identified products supported.


•	Sales and marketing expenses are primarily directly recorded to each segment group based on products supported and sold.


•	General and administrative expenses are generally not allocated to the segments unless directly attributable.


•	Gains, losses and other items, net are not allocated to the segment groups.

We do not track our assets by operating segments. Consequently, it is not practical to show assets by operating segment.

Restructuring Plans

In the three months ended June 30, 2018, the Company recorded a total of $1.3 million in restructuring charges and adjustments included in gains, losses and other items, net in the condensed consolidated statement of operations. The expense related to fiscal year 2018 restructuring plans primarily for associates in the United States required to render service until termination to receive the termination benefits. These costs are expected to be paid out in fiscal 2019.

The expense included severance and other associate-related charges of $3.8 million, and lease accruals and adjustments of $2.6 million.

The associate-related accruals of $3.8 million related to the termination of associates in the United States and Europe. Of all amounts accrued for fiscal year 2018 associate-related plans, $0.7 million remained accrued as of June 30, 2018. These costs are expected to be paid out in fiscal 2019. The lease accruals and adjustments of $2.6 million result from the Company's exit from certain leased office facilities.

The expense included severance and other associate-related charges of $3.8 million, lease accruals and adjustments of $3.0 million, and leasehold improvement write-offs of $2.1 million. Of the associate-related accruals of $3.8 million, $0.2 million remained accrued as of June 30, 2018. These costs are expected to be paid out in fiscal 2019. The lease accruals and adjustments of $3.0 million resulted from the Company's exit from certain leased office facilities ($1.5 million) and adjustments to estimates related to the fiscal 2015 lease accruals ($1.5 million). Of the amount accrued for fiscal 2017 lease accruals, $2.3 million remained accrued as of June 30, 2018.

With respect to the fiscal 2015, 2017, and 2018 lease accruals described above, the Company intends to sublease the facilities to the extent possible. The liabilities will be satisfied over the remainder of the leased properties' terms, which continue through November 2025. Actual sublease receipts may differ from the estimates originally made by the Company. Any future changes in the estimates or in the actual sublease income could require future adjustments to the liabilities, which would impact net earnings (loss) in the period the adjustment is recorded.

COMMITMENTS AND CONTINGENCIES:	Jun. 30, 2018
Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES:	COMMITMENTS AND CONTINGENCIES: Legal Matters The Company is involved in various claims and legal proceedings. Management routinely assesses the likelihood of adverse judgments or outcomes to these matters, as well as ranges of probable losses, to the extent losses are reasonably estimable. The Company records accruals for these matters to the extent that management concludes a loss is probable and the financial impact, should an adverse outcome occur, is reasonably estimable. These accruals are reflected in the Company’s condensed consolidated financial statements. In management’s opinion, the Company has made appropriate and adequate accruals for these matters, and management believes the probability of a material loss beyond the amounts accrued to be remote. However, the ultimate liability for these matters is uncertain, and if accruals are not adequate, an adverse outcome could have a material effect on the Company’s consolidated financial condition or results of operations. The Company maintains insurance coverage above certain limits. There are currently no matters pending against the Company or its subsidiaries for which the potential exposure is considered material to the Company’s condensed consolidated financial statements. Commitments The Company leases data processing equipment, office furniture and equipment, land and office space under noncancellable operating leases. The Company has a future commitment for lease payments over the next 22 years years of $76.5 million. In connection with the disposition of Acxiom Impact during fiscal 2017, the Company assigned a facility lease to the buyer of the business. The Company guaranteed the facility lease as required by the asset disposition agreement. Should the assignee default, the Company would be required to perform under the terms of the facility lease, which continues through September 2021. At June 30, 2018, the Company’s maximum potential future rent payments under this guarantee totaled $2.0 million.

INCOME TAXES:	3 Months Ended
INCOME TAXES:	Jun. 30, 2018
Income Tax Disclosure [Abstract]
INCOME TAXES:	INCOME TAX: In determining the quarterly provision for income taxes, the Company makes its best estimate of the effective income tax rate expected to be applicable for the full fiscal year. The estimated effective income tax rate for the current fiscal year is impacted by the reduction in the U.S. federal corporate income tax rate (discussed below), non-deductible stock-based compensation, state income taxes, research tax credits, and losses in foreign jurisdictions. State income taxes are influenced by the geographic and legal entity mix of the Company's U.S. income as well as the diversity of rules among the states. The Company does not record a tax benefit for certain foreign losses due to uncertainty of future utilization. On December 22, 2017, the U.S. enacted significant tax law changes following the passage of H.R. 1, "An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018 "the Tax Act") (previously known as "The Tax Cuts and Jobs Act"). The Tax Act reduced the U.S. federal corporate income tax rate from 35% to 21%, among other provisions. We believe we have properly estimated our federal and state income tax liabilities for the impacts of the Tax Act, including provisional amounts under SAB No. 118 related to the rate change, the impact of increased bonus depreciation, and the effects on executive compensation deductions. The Tax Act may be subject to technical amendments, as well as interpretations and implementing of regulations by the Department of Treasury and Internal Revenue Service, any of which could increase or decrease one or more impacts of the legislation. As such, we will continue to analyze the effects of the Tax Act and may record adjustments to provisional amounts during the measurement period ending no later than December 31, 2018. As of June 30, 2018, we have not changed the provisional estimates recognized in fiscal 2018. Any impacts to our income tax expense as a result of additional guidance will be recorded in the period in which the guidance is issued.

FAIR VALUE OF FINANCIAL INSTRUMENTS:

Fair Value Disclosures [Abstract]

FAIR VALUE OF FINANCIAL INSTRUMENTS:

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value.

Cash and cash equivalents, trade receivables, unbilled and notes receivable, short-term borrowings and trade payables - The carrying amount approximates fair value because of the short maturity of these instruments.

Long-term debt - The interest rate on the revolving credit agreement is adjusted for changes in market rates and therefore the carrying value approximates fair value. The estimated fair value of other long-term debt was determined based upon the present value of the expected cash flows considering expected maturities and using interest rates currently available to the Company for long-term borrowings with similar terms. At June 30, 2018, the estimated fair value of long-term debt approximates its carrying value.

Under applicable accounting standards financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurements. The Company assigned assets and liabilities to the hierarchy in the accounting standards, which is Level 1 - quoted prices in active markets for identical assets or liabilities, Level 2 - significant other observable inputs and Level 3 - significant unobservable inputs.

The following table presents the balances of assets measured at fair value as of June 30, 2018 (dollars in thousands):

Subsequent Events [Abstract]

SUBSEQUENT EVENT

On July 2, 2018, the Company entered into a definitive agreement to sell Acxiom Marketing Solutions ("AMS") to The Interpublic Group of Companies, Inc. (“IPG”) for $2.3 billion in cash, subject to customary closing adjustments. The transaction is subject to standard regulatory review, Acxiom shareholder approval and other customary closing conditions. In addition:

•	The transaction is expected to close in the third quarter of fiscal 2019; and


•	The Company expects to report a gain on the sale.

The Company expects to realize approximately $1.7 billion in net cash proceeds, after taxes and fees. Following the closing, the Company intends to:


•	Retire its existing $230 million debt balance;


•	Initiate a $500 million cash tender offer for its common stock;


•	Increase its outstanding share repurchase authorization by up to an additional $500 million, and extend the duration of its program to December 31, 2020;

•	Transfer the Acxiom brand name and associated trademarks to IPG; and


•	Rename the Company LiveRamp Holdings, Inc. and, shortly thereafter, begin trading its common stock under the new ticker symbol “RAMP”.

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (Policies)	3 Months Ended
	Jun. 30, 2018
Accounting Policies [Abstract]
Recent Accounting Pronouncements Not Yet Adopted	Accounting Pronouncements Adopted During the Current Year In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) and issued subsequent amendments to the initial guidance in August 2015, March 2016, April 2016, May 2016 and December 2016 within ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, respectively. Topic 606 supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of the new guidance is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We adopted Topic 606 as of April 1, 2018 using the modified retrospective method. See Note 2 for further details. In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 719): Scope of Modification Accounting" ("ASU 2017-09"). ASU 2017-09 clarifies when changes to the terms or conditions of a stock-based payment award must be accounted for as modifications. ASU 2017-09 will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a stock-based payment award if the award's fair value, vesting conditions and classification as an equity or liability instrument are the same immediately before and after the change. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. ASU 2017-09 is effective for the Company beginning in fiscal 2019. We adopted the standard in the current fiscal quarter, and adoption of this guidance did not have a material impact on our condensed financial statements and related disclosures. Recent Accounting Pronouncements Not Yet Adopted In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" ("ASU 2017-04"), which eliminates step two from the goodwill impairment test. Under ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for annual periods beginning after December 15, 2019 (fiscal 2021 for the Company), including interim periods within those fiscal years; earlier adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of this guidance to have a material impact on its condensed financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" ("ASU 2016-02"), as a comprehensive new standard that amends various aspects of existing guidance for leases and requires additional disclosures about leasing arrangements. The new standard will require lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases except short-term leases. For lessees, leases will continue to be classified as either operating or financing in the income statement. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model. Lessors will continue to classify leases as operating, direct financing or sales-type leases. Subsequently, the FASB has issued various ASU's to provide further clarification around aspects of Topic 842. ASU 2016-02 is effective for annual periods beginning after December 15, 2018 (fiscal 2020 for the Company), including interim periods within those fiscal years, with early adoption permitted. We will adopt the new standard on April 1, 2019 using the modified retrospective approach. The Company is continuing to evaluate the impact of the adoption of this guidance on its condensed consolidated financial statements and related disclosures. The Company does not anticipate that the adoption of any other recent accounting pronouncements will have a material impact on the Company's consolidated financial position, results of operations or cash flows.
