ORGANIZATION AND BASIS OF PRESE

ORGANIZATION AND BASIS OF PRESENTATION	9 Months Ended
	Mar. 31, 2016
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	ORGANIZATION AND BASIS OF PRESENTATION Organization Premier, Inc. ("Premier" or the "Company") is a publicly-held, for-profit Delaware corporation primarily owned by hospitals, health systems and other healthcare organizations (such owners of Premier are referred to herein as "member owners") located in the United States and by public stockholders. The Company, together with its subsidiaries and affiliates, is a leading healthcare improvement company that unites hospitals, health systems, physicians and other healthcare providers to improve and innovate in the clinical, financial and operational areas of their businesses to meet the demands of a rapidly evolving healthcare industry. The Company's business model and solutions are designed to provide its members access to scale efficiencies, spread the cost of their development, provide actionable intelligence derived from anonymized data in the Company's data warehouse, mitigate the risk of innovation and disseminate best practices that will help the Company's member organizations succeed in their transformation to higher quality and more cost-effective healthcare. The Company, together with its subsidiaries and affiliates, delivers its integrated platform of solutions through two business segments: supply chain services and performance services. The supply chain services segment includes one of the largest healthcare group purchasing organizations ("GPOs") in the United States, a specialty pharmacy and direct sourcing activities. The performance services segment includes one of the largest informatics and advisory services businesses in the United States focused on healthcare providers. The Company's software as a service ("SaaS") informatics products utilize its comprehensive data set to provide actionable intelligence to its members, enabling them to benchmark, analyze and identify areas of improvement across the three main categories of cost management, quality and safety, and population health management. The performance services segment also includes the Company's technology-enabled performance improvement collaboratives, advisory services and insurance management services. Basis of Presentation and Principles of Consolidation Basis of Presentation The Company, through its wholly-owned subsidiary, Premier Services, LLC ("Premier GP"), holds an approximate 32% controlling general partner interest in, and, as a result, consolidates the financial statements of, Premier Healthcare Alliance, L.P. ("Premier LP"). The limited partners' approximate 68% ownership of Premier LP is reflected as redeemable limited partners' capital in the Company's accompanying condensed consolidated balance sheets, and the limited partners' proportionate share of income in Premier LP is reflected within net income attributable to non-controlling interest in Premier LP in the Company's accompanying condensed consolidated statements of income and within comprehensive income attributable to non-controlling interest in the accompanying condensed consolidated statements of comprehensive income. During the nine months ended March 31, 2016 , the member owners exchanged approximately 7.5 million of their Class B common units and associated Class B common stock for an equal number of Class A common stock as part of their quarterly exchange rights under an exchange agreement (the "Exchange Agreement") entered into by the member owners in connection with the completion of a series of transactions (the "Reorganization") following the consummation of the Company's initial public offering (the "IPO", and collectively with the Reorganization, the "Reorganization and IPO") on October 1, 2013 (see Note 13 - Earnings (Loss) Per Share). As a result of t he February 1, 2016 exchange, member owners’ ownership percentage of the Company’s combined Class A and Class B common stock (“Common Stock”) decreased from approximately 70% at December 31, 2015 to approximately 68% at March 31, 2016 through their ownership of Class B common stock. The ownership percentage of public investors’ ownership percentage, which may include member owners that have received shares of Class A common stock in connection with previous exchanges, increased from approximately 30% at December 31, 2015 to approximately 32% at March 31, 2016 . Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Accordingly, certain information and disclosures normally included in annual financial statements have been condensed or omitted. The accompanying condensed consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of results of operations and financial condition for the interim periods shown, including normal recurring adjustments. The Company believes that the disclosures are adequate to make the information presented not misleading and should be read in conjunction with the audited consolidated financial statements and related footnotes contained in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2015 (the "2015 Annual Report") filed with the SEC on August 26, 2015. Use of Estimates in the Preparation of Financial Statements The preparation of the Company's condensed consolidated financial statements in accordance with GAAP requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. Significant estimates including estimates for allowances for doubtful accounts, useful lives of property and equipment, stock-based compensation, payables under tax receivable agreements, values of investments not publicly traded, the valuation allowance on deferred tax assets, uncertain income taxes, deferred revenue, future cash flows associated with asset impairments, and the allocation of purchase price are evaluated on an ongoing basis. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES	9 Months Ended
	Mar. 31, 2016
Accounting Policies [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES There have been no material changes to the Company's significant accounting policies as described in the 2015 Annual Report, other than the balance sheet classification of deferred taxes discussed below and in Note 15 - Income Taxes. Recently Adopted Accounting Standards In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-17 Balance Sheet Classification of Deferred Taxe s as part of their simplification initiatives. The update requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The Company early adopted this standard as allowed as of December 31, 2015. The Company retroactively adjusted deferred tax assets and liabilities as they would have been reported at June 30, 2015 in accordance with ASU 2015-17 (see Note 15 - Income Taxes). In September 2015, the FASB issued ASU 2015-16 Simplifying the Accounting Measurement-Period Adjustments . Under this standard, an acquirer must recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The effect on earnings of changes in depreciation or amortization, or other income effects (if any) as a result of the change to the provisional amounts, calculated as if the accounting had been completed as of the acquisition date, must be recorded in the reporting period in which the adjustment amounts are determined rather than retrospectively. This standard also requires that the acquirer present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The Company early adopted the new standard as allowed effective January 1, 2016. The adoption of ASU 2015-16 did not result in any significant changes in the Company's result of operations or statement of position. For further information, see Note 7 - Goodwill. Recently Issued Accounting Standards Not Yet Adopted In March 2016, the FASB issued ASU No. 2016-09 Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting which is intended to simplify the accounting for employee share-based payments. The amendments in this updated guidance include changes to simplify the accounting for share-based payment transactions, including the income tax consequences, classification of such share-based awards as either equity or liabilities and classification in the statement of cash flows. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The new standard will be effective for the Company for the fiscal year beginning July 1, 2017. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of the new standard on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02 Leases (Topic 842) which is intended to increase transparency and comparability among organizations of accounting for leasing arrangements. This guidance establishes a right-of-use model that requires a lessee to record a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. Entities will be required to recognize and measure leases as of the earliest period presented using a modified retrospective approach. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The new standard will be effective for the Company for the fiscal year beginning July 1, 2019. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of the new standard on its consolidated financial statements and related disclosures. In January 2016, the FASB issued ASU No. 2016-01 Recognition and Measurement of Financial Assets and Financial Liabilities which is intended to provide users of financial statements with more useful information on the recognition, measurement, presentation, and disclosure of financial instruments. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The new standard will be effective for the Company for the fiscal year beginning July 1, 2018. Early adoption is permitted for financial statements that have not been issued. The Company is currently evaluating the impact of the adoption of the new standard on its consolidated financial statements and related disclosures. In August 2015, the FASB issued ASU 2015-15 Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements which clarifies the SEC staff’s position on presenting and measuring debt issuance costs incurred in connection with line-of-credit arrangements given the lack of guidance on this topic in ASU 2015-03 Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs. The SEC staff has announced that it would “not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement.” This standard will be effective retrospectively for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The new standard will be effective for the Company for the fiscal year beginning July 1, 2016. Early adoption is permitted for financial statements that have not been previously issued. The Company is currently evaluating the impact of the adoption of the new standard on its consolidated financial statements and related disclosures. In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory , which requires entities to measure most inventory “at the lower of cost and net realizable value,” thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market. This guidance will not apply to inventories that are measured by using either the last-in, first-out method or the retail inventory method. The new standard will be effective prospectively for annual periods beginning after December 15, 2016, and interim periods therein. The new standard will be effective for the Company for the fiscal year beginning July 1, 2017. Early adoption is permitted. Upon transition, entities must disclose the nature of and reason for the accounting change. The Company is currently evaluating the impact of the adoption of the new standard on its consolidated financial statements and related disclosures. In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis , which effectively eliminates the presumption that a general partner should consolidate a limited partnership, modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIE"s) or voting interest entities, and affects the consolidation analysis of reporting entities that are involved with VIEs (particularly those that have fee arrangements and related party relationships). In some cases, consolidation conclusions will change under the new guidance and, in other cases, a reporting entity will provide additional disclosures if an entity that currently is not considered a VIE is considered a VIE under the new guidance. The new standard will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2015 and early adoption is permitted. The new standard allows for either full retrospective or modified retrospective adoption. The new standard will be effective for the Company for the fiscal year beginning July 1, 2016. The Company has completed its preliminary evaluation and believes there is no impact from the adoption of the new standard on its consolidated financial statements other than providing additional disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , which will supersede nearly all existing revenue recognition guidance. The new standard requires revenue to be recognized 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. The new standard also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The new standard allows for either full retrospective or modified retrospective adoption. The FASB subsequently issued an amendment in ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , in August 2015 to defer the effective date of the new standard for all entities by one year. The new standard, as amended, will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and early adoption as of the original effective date for public entities will be permitted. ASU 2014-09, as amended, will be effective for the Company for the fiscal year beginning July 1, 2018. The FASB issued another amendment in ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations , in March 2016 related to a third party providing goods or services to a customer. When another party is involved in providing goods or services to a customer, an entity is required to determine whether the nature of its promise is to provide the specified good or service itself, the entity acts as a principal. If an entity arranges for the good or service to be provided by a third party, the entity acts as an agent. The amendment requires principals to recognize revenue for the gross amount and agents to recognize revenue for the amount of any fee or commission it expects to be entitled. The amendment will be effective with ASU 2014-09. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing , which amends specific aspects of ASU 2014-09, Revenue from Contracts with Customers, including how to identify performance obligations and guidance related to licensing implementation. This amendment provides guidance on determining whether an entity's promise to grant a license provides a customer with either a right to use the entity's intellectual property or a right to access the entity's intellectual property. The amendment will be effective with ASU 2014-09. The Company is currently evaluating the transition method that will be elected as well as the impact of the adoption of ASU 2014-09, as amended, on its consolidated financial statements and related disclosures. The Company is also evaluating the impact of the deferral of the effective date on its plans for adopting the new standard.

Business Combinations [Abstract]
Business Acquisitions	BUSINESS ACQUISITIONS Acquisition of InFlowHealth, LLC On October 1, 2015, the Company’s consolidated subsidiary, Premier Healthcare Solutions, Inc. ("PHSI") acquired all of the limited liability company membership interests of InFlow for $6.1 million in cash, subject to post-closing adjustments based on InFlow’s actual (i) indebtedness, (ii) transaction expenses and (iii) net working capital at closing. The acquisition provides selling members an earn-out opportunity of up to $26.9 million based on InFlow’s future annual contractual subscription revenues above certain thresholds through December 31, 2019. As of March 31, 2016 , the Company valued the earn-out at $4.1 million related to the contingent purchase price, of which $0.7 million is classified as current and included in other current liabilities and $3.4 million is classified as long-term and included in other non-current liabilities in the condensed consolidated balance sheet. In accordance with GAAP, the contingent consideration is recorded at fair value based on a probability-weighted approach including multiple earnings scenarios, although this value is not indicative of a known amount to be paid. The selling members also received restricted stock units of the Company with an aggregate equity grant value of $2.1 million , which vest over a three -year period with restrictions tied to continued employment. InFlow is a SaaS-based software developer that specializes in improving the operational, financial and strategic performance of physician practices. InFlow’s software allows physicians to identify opportunities for improvement and guide physician practice budgeting and strategic investments by aggregating financial and operational data from physicians in medical groups across the United States. The software is designed to provide actionable insights into among other things, practice capacity, patient volumes, productivity and staffing ratios, revenue cycle performance, patient demographics, referral patterns, and overall compensation. The Company has accounted for the InFlow acquisition as a business combination whereby the purchase price was allocated to tangible and intangible assets (see Note 6 - Intangible Assets, Net) acquired and liabilities assumed based on their preliminary fair values. The InFlow acquisition resulted in the recognition of approximately $5.9 million of goodwill (see Note 7 - Goodwill) attributable to the anticipated profitability of InFlow. The Company reports InFlow as part of its performance services segment. The InFlow acquisition is considered an asset acquisition for tax purposes. Accordingly, the Company expects the goodwill to be deductible for tax purposes. The purchase price allocation for the InFlow acquisition is preliminary and subject to changes in fair value of working capital, valuation of the assets acquired and the liabilities assumed. The calculation of the earn-out is based on future revenues as defined in the purchase agreement. In accordance with GAAP, the Company is required to fair-value the earn-out liability at each reporting period with any adjustments to the earn-out recorded in earnings under other expenses, net. For the six months ended December 31, 2015 , the Company overstated cash flows used in investing activities by $4.1 million and overstated cash flows provided by operating activities by $4.1 million related to the earn-out liability for InFlow. The Company has corrected the cash flow statement as of the nine months ended March 31, 2016 in the condensed consolidated financial statements. Acquisition of CECity.com, Inc. On August 20, 2015, PHSI acquired 100% of the outstanding shares of capital stock of CECity.com, Inc. (“CECity”), a Delaware corporation, for $398.3 million , subject to post-closing adjustments based on CECity's actual (i) net working capital, (ii) cash and cash equivalents and (iii) indebtedness at closing. The Company funded the acquisition with $250.0 million of cash and $150.0 million of borrowings under the Company’s credit facility (see Note 9 - Debt). CECity is a cloud-based healthcare solutions provider, specializing in performance management and improvement, pay-for-value reporting and professional education. CECity offers turnkey solutions for clinical data registries, continuing medical education, maintenance of certification, performance improvement, pay-for-value reporting and life-long professional development. The Company has accounted for the CECity acquisition as a business combination whereby the purchase price was allocated to tangible and intangible assets (see Note 6 - Intangible Assets, Net) acquired and liabilities assumed based on their preliminary fair values. The CECity acquisition resulted in the recognition of approximately $273.9 million of goodwill (see Note 7 - Goodwill) which reflects a premium relative to the fair value of the identified assets due to the strategic importance of the transaction to the Company and the CECity business model which does not rely extensively on tangible assets as well as the anticipated profitability of CECity. The CECity acquisition is considered an asset acquisition for tax purposes. Accordingly, the Company expects the goodwill to be deductible for tax purposes. The purchase price allocation for the CECity acquisition is preliminary and subject to changes in fair value of working capital and the valuation of the assets acquired and the liabilities assumed. The following table summarizes the preliminary fair values assigned to the net assets acquired and the liabilities assumed as of the CECity acquisition date of August 20, 2015 (in thousands): Acquisition Date Fair Value Purchase price $ 400,000 Working capital adjustment (28 ) Total purchase price 399,972 Less: cash acquired (1,708 ) Total purchase price, net of cash acquired 398,264 Accounts receivable 3,937 Other current assets 295 Property and equipment 605 Intangible assets 125,400 Total assets acquired 130,237 Other current liabilities 5,871 Total liabilities assumed 5,871 Goodwill $ 273,898 Approximately $0.5 million and $3.3 million of pretax transaction-related costs related to the CECity acquisition are recorded in selling, general and administrative expenses in the accompanying condensed consolidated statement of income for the three and nine months ended March 31, 2016 , respectively. The Company reports CECity as part of its performance services segment. Pro forma results of operations for this acquisition have not been presented because the effects on revenue and net income were not material to our historic condensed consolidated financial statements. Acquisition of Healthcare Insights, LLC On July 31, 2015, PHSI acquired all of the limited liability company membership interests of Healthcare Insights, LLC (“HCI”) for $64.3 million in cash, subject to post-closing adjustments based on HCI’s actual (i) indebtedness, (ii) transaction expenses and (iii) net working capital at closing. The acquisition also provides selling members with an earn-out opportunity of up to $4.0 million based on HCI’s revenues during the 12 months ending December 31, 2017 as defined in the purchase agreement. As of March 31, 2016, the fair value of the earn-out liability related to the HCI acquisition is zero . HCI has two primary businesses exclusively serving the healthcare provider market: (i) financial analytics which includes budgeting, forecasting, and labor productivity applications, and (ii) clinical analytics which includes service line analytics and direct costing analytics to support value-based care. The Company has accounted for the HCI acquisition as a business combination whereby the purchase price was allocated to tangible and intangible assets (see Note 6 - Intangible Assets, Net) acquired and liabilities assumed based on their preliminary fair values. The HCI acquisition resulted in the recognition of approximately $42.4 million of goodwill (see Note 7 - Goodwill) attributable to the anticipated profitability of HCI. The Company reports HCI as part of its performance services segment. The HCI acquisition is considered an asset acquisition for tax purposes. Accordingly, the Company expects the goodwill to be deductible for tax purposes. The purchase price allocation for the HCI acquisition is preliminary and subject to changes in fair value of working capital, valuation of the assets acquired and the liabilities assumed. The calculation of the earn-out is based on future revenues as defined in the purchase agreement. In accordance with GAAP, the Company is required to fair-value the earn-out liability at each reporting period with any adjustments to the earn-out recorded in earnings in other expense, net.

The Credit Facility provides for borrowings of up to $750.0 million with (i) a $25.0 million sub-facility for standby letters of credit and (ii) a $75.0 million sub-facility for swingline loans. The Credit Facility may be increased from time to time at the Company's request by up to an aggregate additional amount of $250.0 million , subject to lender approval. The Credit Facility includes an unconditional and irrevocable guaranty of all obligations under the Credit Facility by Premier GP, certain domestic subsidiaries of Premier GP and future guarantors, if any. Premier, Inc. is not a guarantor under the Credit Facility. At the Company's option, committed loans may be in the form of eurodollar rate loans (“Eurodollar Loans”) or base rate loans (“Base Rate Loans”). Eurodollar Loans bear interest at the eurodollar rate (defined as the London Interbank Offered Rate, or LIBOR, plus the Applicable Rate (defined as a margin based on the Consolidated Total Leverage Ratio (as defined in the Credit Facility)). Base Rate Loans bear interest at the Base Rate (defined as the highest of the prime rate announced by the administrative agent, the federal funds effective rate plus 0.50% or the one-month LIBOR plus 1.0% ) plus the Applicable Rate. The Applicable Rate ranges from 1.125% to 1.75% for Eurodollar Loans and 0.125% to 0.75% for Base Rate Loans. To fund the CECity acquisition the Company utilized $150.0 million of the Credit Facility (see Note 3 - Business Acquisitions), of which $50.0 million was repaid in November 2015 and $50.0 million was repaid in February 2016. At March 31, 2016, the interest rate for the three month Eurodollar Loans was 1.745% . The Co-Borrowers are required to pay a commitment fee ranging from 0.125% to 0.25% per annum on the actual daily unused amount of commitments under the Credit Facility. At March 31, 2016 , the commitment fee was 0.125% . As of March 31, 2016 , the Company had approximately $ 25.0 million available for credit commitments. The Credit Facility contains customary representations and warranties as well as customary affirmative and negative covenants, including, among others, limitations on liens, indebtedness, fundamental changes, dispositions, restricted payments and investments. Under the terms of the Credit Facility, Premier GP is not permitted to allow its consolidated total leverage ratio (as defined in the Credit Facility) to exceed 3.00 to 1.00 for any period of four consecutive quarters.

The Company may prepay amounts outstanding under the Credit Facility without premium or penalty provided that Co-Borrowers compensate the lenders for losses and expenses incurred as a result of the prepayment of any Eurodollar Loan, as defined in the Credit Facility. Notes Payable Notes payable consist primarily of non-interest bearing notes payable outstanding to departed member owners and generally have stated maturities of five years from their date of issuance.

(b) Earn-out liabilities incurred in connection with acquisitions of InFlow and HCI. Cash equivalents are included in cash and cash equivalents; commercial paper, corporate debt securities, U.S. government debt securities and asset-backed securities are included in current and long-term marketable securities (see Note 5 - Marketable Securities); the current portion of deferred compensation plan assets is included in prepaid expenses and other current assets ( $1.9 million and $2.6 million at March 31, 2016 and June 30, 2015 , respectively) in the accompanying condensed consolidated balance sheets. The fair value of the Company's commercial paper, corporate debt securities, U.S. government debt securities and asset-backed securities, classified as Level 2, are valued using quoted prices for similar securities in active markets or quoted prices for identical or similar securities in markets that are not active. The Company had no assets or liabilities for which fair value is measured on a recurring basis at June 30, 2015 that would be classified as Level 3. At March 31, 2016, the Company's earn-out liabilities are classified as Level 3. The fair value of the earn-out liabilities was determined using the Monte Carlo simulation method. Non-Recurring Fair Value Measurements During the three and nine months ended March 31, 2016 , no non-recurring fair value measurements were required relating to the testing of goodwill and intangible assets for impairment, however the purchase price allocations required significant non-recurring Level 3 inputs (see Note 3 - Business Acquisitions). The preliminary fair values of the acquired intangible assets resulting from the acquisitions of CECity, HCI and InFlow were determined using the income approach. Other Financial Instruments The fair value of cash, accounts receivable, accounts payable and accrued liabilities approximates carrying value because of the short-term nature of these financial instruments. The carrying amount of the Credit Facility at March 31, 2016 approximates fair value based on the variable nature of the interest thereupon and the consistency of the three and six-month LIBOR since drawing on the Credit Facility in August 2015. The fair value of non-interest bearing notes payable, classified as Level 2, is less than their carrying value by approximately $0.7 million and $0.6 million at March 31, 2016 and June 30, 2015 , respectively, based on an assumed market interest rate of 2.0% at March 31, 2016 and 1.6% at June 30, 2015 , respectively.

REDEEMABLE LIMITED PARTNERS' CA

Temporary Equity Disclosure [Abstract]
Redeemable Limited Partners' Capital	REDEEMABLE LIMITED PARTNERS' CAPITAL Pursuant to the terms of the historical limited partnership agreement of Premier LP in effect prior to the Reorganization and IPO, Premier LP was required to repurchase a limited partner's interest in Premier LP upon the sale of such limited partner's shares of PHSI common stock, such limited partner's withdrawal from Premier LP or such limited partner's failure to comply with the applicable purchase commitments under such limited partnership agreement of Premier LP. As a result, the redeemable limited partners' capital is classified as temporary equity in the mezzanine section of the accompanying condensed consolidated balance sheets since (i) the withdrawal is at the option of each limited partner and (ii) the conditions of the repurchase are not solely within the Company's control. Upon the consummation of the Reorganization and IPO, each limited partner's shares of PHSI were contributed for Class B common units of Premier LP. Commencing on October 31, 2014, and during each year thereafter, each limited partner has the cumulative right to exchange up to one-seventh of its initial allocation of Class B common units for shares of Class A common stock, cash or a combination of both, the form of consideration to be at the discretion of the Company's independent audit committee of the board of directors. Redeemable limited partners' capital represents the member owners' 68% ownership of Premier LP at March 31, 2016 . The limited partners hold the majority of the votes of the board of directors and any redemption or transfer or choice of consideration cannot be assumed to be within the control of the Company. As such, classification outside of permanent equity is required and the redeemable limited partners' capital is recorded at the redemption amount, which represents the greater of the book value or redemption amount per the Amended and Restated Limited Partnership Agreement of Premier LP (as amended, the "LP Agreement") in the mezzanine section of the accompanying condensed consolidated balance sheets at March 31, 2016 and June 30, 2015. As previously discussed, the Company records redeemable limited partners' capital at the greater of the book value or redemption amount per the LP Agreement that the Company calculates as the fair value of all Class B common units, as if immediately exchangeable into Class A common shares. For the nine months ended March 31, 2016 and 2015 the Company recorded an adjustment to fair value for the redemption amount to redeemable limited partners' capital of $(685.6) million and $812.0 million , respectively. During the nine months ended March 31, 2016 , the Company recorded a reduction of $260.6 million to redeemable limited partners' capital to reflect the exchange of Class B common units and associated shares of Class B common stock by the member owners for an equal number of shares of the Company's Class A common stock pursuant to the terms of the Exchange Agreement (see Note 13 - Earnings (Loss) Per Share). The table below shows the changes in the redeemable limited partners' capital classified as temporary equity from June 30, 2015 to March 31, 2016 (in thousands): Receivables From Limited Partners Redeemable Limited Partners' Capital Accumulated Other Comprehensive Loss Total Redeemable Limited Partners' Capital June 30, 2015 $ (11,633 ) $ 4,091,473 $ (8 ) $ 4,079,832 Distributions and notes payable applied to receivables from limited partners 4,813 — — 4,813 Redemption of limited partners — (3,614 ) — (3,614 ) Net income attributable to Premier LP — 153,735 — 153,735 Distributions to limited partners — (70,276 ) — (70,276 ) Net unrealized loss on marketable securities — — (157 ) (157 ) Exchange of Class B common units for Class A common stock by member owners — (260,598 ) — (260,598 ) Adjustment to redemption amount — (685,649 ) — (685,649 ) March 31, 2016 $ (6,820 ) $ 3,225,071 $ (165 ) $ 3,218,086 Receivables from limited partners represent amounts due from limited partners for their required capital in Premier LP. These receivables are either interest bearing notes issued to new limited partners or non-interest bearing loans (contribution loans) provided to existing limited partners and are reflected as a reduction in redeemable limited partners' capital (which includes the capital funded by such receivables) because amounts due from limited partners for capital are not reflected as redeemable limited partnership capital until paid. No interest bearing notes receivable were executed by limited partners of Premier LP during the nine months ended March 31, 2016 . During the nine months ended March 31, 2016 , five limited partners withdrew from Premier LP. The limited partnership agreement provides for the redemption of the former limited partner's Class B common units that are not eligible for exchange in the form of a five -year, unsecured, non-interest bearing term promissory note, a cash payment equal to the present value of the redemption amount or other mutually agreed upon terms. Partnership interest obligations to the former limited partners are reflected in notes payable in the accompanying condensed consolidated balance sheets. In connection with such withdrawals, the Company issued $2.9 million in five -year, unsecured, non-interest bearing term promissory notes at the redemption amount per the LP Agreement. Upon the consummation of the Reorganization and IPO, Premier LP amended its distribution policy in which cash distributions will be required, as long as taxable income is generated and cash is available to distribute, on a quarterly basis prior to the 60 th day after the end of each calendar quarter. The Company makes quarterly distributions to its limited partners in the form of a legal partnership income distribution governed by the terms of the LP Agreement. These partner distributions are based on the limited partner’s ownership in Premier LP and relative participation across Premier service offerings. While these distributions are based on relative participation across Premier service offerings, it is not based directly on revenue generated from an individual partner’s participation as the distributions are based on the net income or loss of the partnership which encompass the operating expenses of the partnership as well as participation by non-owner members in Premier’s service offerings. To the extent Premier LP incurred a net loss, the partners would not receive a quarterly distribution. As provided in the LP Agreement, the amount of actual cash distributed may be reduced by the amount of such distributions used by limited partners to offset contribution loans or other amounts payable to the Company. Premier LP made a quarterly distribution on August 27, 2015 to its limited partners of $22.4 million , which is equal to Premier LP's total taxable income for the three months ended June 30, 2015 multiplied by the Company's standalone effective combined federal, state and local income tax rate. Premier LP made a quarterly distribution on November 29, 2015 to its limited partners of $23.1 million , which is equal to Premier LP's total taxable income for the three months ended September 30, 2015 multiplied by the Company's standalone effective combined federal, state and local income tax rate. Premier LP made a quarterly distribution on February 25, 2016 to its limited partners of $22.5 million , which is equal to Premier LP's total taxable income for the three months ended December 31, 2015 multiplied by the Company's standalone effective combined federal, state and local income tax rate. Premier LP will make a quarterly distribution on or before May 29, 2016 to its limited partners of $24.7 million , which is equal to Premier LP's total taxable income for the three months ended March 31, 2016 multiplied by the Company's stand-alone effective combined federal, state and local income tax rate. The distribution is reflected in limited partners' distribution payable in the accompanying condensed consolidated balance sheet at March 31, 2016 .

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share of Premier is computed by dividing net income (loss) attributable to stockholders by the weighted average number of shares of common stock outstanding for the period. Net income (loss) attributable to stockholders includes the adjustment recorded in the period to reflect redeemable limited partners' capital at the redemption amount, as a result of the exchange benefit obtained by limited partners through the ownership of Class B common units. Except when the effect would be anti-dilutive, the diluted earnings per share calculation, which is calculated using the treasury stock method, includes the impact of non-vested restricted stock units and awards, shares of non-vested performance share awards, shares that could be issued under the outstanding stock options and Class B common units issued if all exchanges occurred. The following table provides a reconciliation of common shares used for basic earnings (loss) per share and diluted earnings (loss) per share (in thousands, except per share amounts): Three months ended March 31, Nine months ended March 31, 2016 2015 2016 2015 Numerator for basic earnings (loss) per share: Net income (loss) attributable to stockholders $ 299,948 $ (374,853 ) $ 716,719 $ (781,216 ) Numerator for diluted earnings (loss) per share: Net income attributable to stockholders $ 299,948 $ — $ 716,719 $ — Adjustment of redeemable limited partners' capital to redemption amount (284,409 ) — (685,649 ) — Net income attributable to non-controlling interest in Premier LP 56,018 — 153,735 — Net income 71,557 — 184,805 — Tax effect on Premier Inc. net income (a) (9,551 ) — (34,639 ) — Adjusted net income $ 62,006 $ — $ 150,166 $ — Denominator for basic earnings (loss) weighted average shares (b) 44,716 37,316 41,329 35,066 Denominator for diluted earnings (loss) per share: Effect of dilutive securities: (c) Stock options 249 — 290 — Restricted stock 610 — 553 — Performance share awards 1,606 — 1,329 — Class B shares outstanding 97,837 — 102,057 — Denominator for diluted earnings (loss) per share-adjusted: Weighted average shares and assumed conversions 145,018 37,316 145,558 35,066 Basic earnings (loss) per share $ 6.71 $ (10.05 ) $ 17.34 $ (22.28 ) Diluted earnings (loss) per share $ 0.43 $ (10.05 ) $ 1.03 $ (22.28 ) (a) Represents income tax expense related to Premier, Inc. retaining the portion of net income attributable to income from non-controlling interest in Premier, LP for the purpose of diluted earnings per share.

Further, 106,659 Class B common units exchangeable for Class A common shares was excluded from the dilutive weighted average shares outstanding because to do so would have been anti-dilutive for the period presented. Pursuant to the terms of the Exchange Agreement, Premier has issued, on a quarterly basis, shares of Class A common stock to member owners in exchange for an equal number of Class B common units of Premier LP. In connection with the exchange of Class B common units by member owners, shares of Premier's Class B common stock are surrendered by member owners and retired (see Note 11 - Redeemable Limited Partners' Capital). The following table presents certain information regarding the exchange of Class B common units and associated Class B common stock for Premier's Class A common stock in connection with the quarterly exchanges pursuant to the terms of the Exchange Agreement.

Vested stock options will expire either after 12 months of an employee's termination with Premier or immediately upon an employee's termination with Premier, depending on the termination circumstances. Stock options generally vest in equal annual installments over three years. The following table includes information related to stock options for the nine months ended March 31, 2016 : Number of Options Weighted Average Exercise Price Outstanding at June 30, 2015 2,643,078 $ 28.24 Granted 860,765 $ 35.48 Exercised (91,439 ) $ 27.55 Forfeited (42,571 ) $ 33.53 Outstanding at March 31, 2016 3,369,833 $ 30.04 Outstanding and exercisable at March 31, 2016 1,443,077 $ 27.67 The aggregate intrinsic value of stock options outstanding at March 31, 2016 was $13.2 million . The aggregate intrinsic value of stock options outstanding and exercisable at March 31, 2016 was $8.2 million .

At March 31, 2016 , there was $14.2 million of unrecognized stock-based compensation expense related to stock options that will be amortized over 1.89 years . The Company estimates the fair value of each stock option on the date of grant using a Black-Scholes option-pricing model, applying the following assumptions and amortizes expense over the option's vesting period using the straight-line attribution approach: March 31, 2016 2015 Expected life (1) 6 years 6 years Expected dividend (2) — — Expected volatility (3) 32.70% - 33.50% 36.20% - 39.50% Risk-free interest rate (4) 1.37% - 1.82% 1.66% - 1.84% Weighted average option grant date fair value $11.28 - $12.40 $12.82 - $13.77 (1) The six -year expected life (estimated period of time outstanding) of stock options granted was estimated using the "Simplified Method" which utilizes the midpoint between the vesting date and the end of the contractual term. This method was utilized for the stock options due to the lack of historical exercise behavior of Premier's employees. (2) No dividends are expected to be paid over the contractual term of the stock options granted, resulting in the use of a zero expected dividend rate. (3) The expected volatility rate is based on the observed historical volatilities of comparable companies. (4) The risk-free interest rate was interpolated from the five -year and seven -year United States Treasury constant maturity market yield as of the date of the grant.

INCOME TAXES

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company's income tax expense is attributable to the activities of the Company, PHSI and PSCI, all of which are subchapter C corporations. Under the provisions of federal and state statutes, Premier LP is not subject to federal and state income taxes. For federal and state income tax purposes, income realized by Premier LP is taxable to its partners. The Company, PHSI and PSCI are subject to U.S. federal and state income taxes. For the three months ended March 31, 2016 and 2015, the Company recorded tax expense on income before income taxes of $9.5 million and $2.0 million , respectively, which equates to an effective tax rate of 11.7% and 2.7% , respectively. The effective tax rate has increased from prior year primarily attributable to the recording of valuation allowances against deferred tax assets at PHSI. The Company’s effective tax rate differs from income taxes recorded at the statutory rate primarily due to partnership income not subject to federal income taxes, state and local taxes and nondeductible expenses. For the nine months ended March 31, 2016 and 2015, the Company recorded tax expense on income before income taxes of $41.3 million and $12.1 million , respectively, which equates to an effective tax rate of 18.3% and 5.6% , respectively. The effective tax rate has increased from prior year primarily attributable to the recording of valuation allowances against deferred tax assets at PHSI and discrete tax expense at Premier associated with a 1% reduction in the North Carolina state income tax for years 2016 and beyond that was not present in the prior year. The Company's effective income tax rate differs from income taxes recorded at the statutory rate primarily due to partnership income not subject to federal income taxes, state and local taxes and nondeductible expenses. The Company has deferred tax assets of $423.8 million and $353.7 million as of March 31, 2016 and June 30, 2015 , respectively. The increase of $70.1 million is primarily attributable to the increases of $ 97.1 million in connection with the exchange of member owner Class B common units pursuant to the Exchange Agreement that occurred during the nine months ended March 31, 2016 and $9.7 million recorded in the ordinary course of business offset by the reductions in deferred tax assets of $8.0 million recorded in connection with adjusting the basis in assets related to the North Carolina state income tax rate reduction, a $4.7 million decrease in deferred tax assets attributable to tax receivable agreements due to departed member owners, and a valuation allowance recorded against deferred tax assets of $24.0 million at PHSI. The Company has tax receivable agreements liabilities of $289.3 million as of March 31, 2016 , representing 85% of the tax savings payable to limited partners that the Company expects to receive in connection with the Section 754 election which results in adjustments to the tax basis of the assets of Premier LP upon member owner exchanges of Class B common units of Premier LP for Class A common stock of Premier, Inc. and represents an increase of $53.4 million when compared to the $235.9 million as of June 30, 2015 . The increase is attributable to a $ 70.4 million increase in connection with quarterly member owner exchanges on July 31, 2015, November 2, 2015, and February 1, 2016 offset by a $4.8 million decrease in connection with revaluing the deferred tax assets and tax receivable liabilities associated with the North Carolina state income tax rate reduction and $12.2 million decrease in connection with departed member owners. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes , which requires companies to classify all deferred tax assets and liabilities as non-current on the balance sheet instead of separating into current and non-current. As noted in Note 2 - Significant Accounting Policies, the Company elected to early adopt the provisions of this guidance on a retrospective basis the result of which was to reclassify approximately $8.0 million of deferred tax assets classified as current to non-current at June 30, 2015. In accordance with the prescribed guidance, the Company’s condensed consolidated balance sheet at June 30, 2015 has been retrospectively adjusted to apply the new guidance as summarized in the table below (in thousands): June 30, 2015 June 30, 2015 As Reported Adjustment As Adjusted Deferred income tax asset - current $ 8,005 $ (8,005 ) $ — Deferred income tax asset 345,718 8,005 353,723 Total $ 353,723 $ — $ 353,723

Non-recurring items are expenses that have not been incurred within the prior two years and are not expected to recur within the next two years. Operating expenses directly attributable to the segment include expenses associated with sales and marketing, general and administrative and product development activities specific to the operation of each segment. General and administrative corporate expenses that are not specific to a particular segment are not included in the calculation of Segment Adjusted EBITDA. All reportable segment revenues are presented net of inter-segment eliminations and represent revenues from external customers. The following tables present selected net revenue and Segment Adjusted EBITDA (in thousands): Three months ended March 31, Nine months ended March 31, Net Revenue 2016 2015 2016 2015 Supply Chain Services Net administrative fees $ 131,270 $ 117,959 $ 369,952 $ 337,157 Other services and support 1,104 740 2,963 1,192 Services 132,374 118,699 372,915 338,349 Products 80,010 73,438 239,107 203,698 Total Supply Chain Services $ 212,384 $ 192,137 $ 612,022 $ 542,047 Performance Services 86,285 69,586 249,151 198,429 Total $ 298,669 $ 261,723 $ 861,173 $ 740,476 Three months ended March 31, Nine months ended March 31, Segment Adjusted EBITDA 2016 2015 2016 2015 Supply Chain Services $ 118,704 $ 101,600 $ 329,642 $ 290,210 Performance Services 30,771 26,166 90,158 67,717 Corporate (29,546 ) (24,021 ) (78,819 ) (64,856 ) Total $ 119,929 $ 103,745 $ 340,981 $ 293,071 A reconciliation of Segment Adjusted EBITDA to income before income taxes is as follows (in thousands): Three months ended March 31, Nine months ended March 31, 2016 2015 2016 2015 Segment Adjusted EBITDA $ 119,929 $ 103,745 $ 340,981 $ 293,071 Depreciation and amortization (13,110 ) (11,538 ) (37,174 ) (33,107 ) Amortization of purchased intangible assets (8,740 ) (2,554 ) (24,058 ) (6,598 ) Acquisition related expenses (a) (2,583 ) (2,863 ) (11,699 ) (6,408 ) Strategic and financial restructuring expenses (b) (33 ) (2 ) (268 ) (1,281 ) Stock-based compensation expense (c) (11,839 ) (7,285 ) (37,093 ) (21,129 ) ERP implementation expenses (d) (1,162 ) — (3,240 ) — Adjustment to tax receivable agreement liability (e) — (1,073 ) 4,818 — Acquisition related adjustment - deferred revenue (f) (1,077 ) (3,563 ) (5,216 ) (9,224 ) Equity in net income of unconsolidated affiliates (g) (6,627 ) (5,197 ) (16,002 ) (14,812 ) Deferred compensation plan expense — (759 ) 2,073 209 Operating income $ 74,758 $ 68,911 $ 213,122 $ 200,721 Equity in net income of unconsolidated affiliates (g) 6,627 5,197 16,002 14,812 Interest and investment (expense) income, net (285 ) 204 (981 ) 517 Loss on investment — (1,000 ) — (1,000 ) Other expense, net — 743 (2,081 ) (219 ) Income before income taxes $ 81,100 $ 74,055 $ 226,062 $ 214,831 (a) Represents legal, accounting and other expenses related to acquisition activities.

(d) Represents implementation and other costs associated with the implementation of a new enterprise resource planning ("ERP") system. (e) Represents adjustment to tax receivable agreement liability for a 1% decrease in the North Carolina state income tax rate during the nine months ended March 31, 2016 and adjustment to tax receivable agreements liability due to impact of departed member owners during the three months ended March 31, 2015 . (f) Represents non-cash adjustment to deferred revenue of acquired entities. Business combination accounting rules require the Company to record a deferred revenue liability at its fair value only if the acquired deferred revenue represents a legal performance obligation assumed by the acquirer. The fair value is based on direct and indirect incremental costs of providing the services plus a normal profit margin. Generally, this results in a reduction to the purchased deferred revenue balance, which was based on upfront fees associated with software license updates and product support contracts assumed in connection with acquisitions. Because these support contracts are typically one year in duration, our GAAP revenues for the one year period subsequent to the acquisition of a business do not reflect the full amount of support revenues on these assumed support contracts that would have otherwise been recorded by the acquired entity. The Non-GAAP adjustment to software license updates and product support revenues is intended to include, and thus reflect, the full amount of such revenues. (g) Represents equity in net income of unconsolidated affiliates primarily generated by the Company's 50% ownership interest in Innovatix, all of which is included in the supply chain services segment.

SIGNIFICANT ACCOUNTING POLICI26

SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Mar. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company, through its wholly-owned subsidiary, Premier Services, LLC ("Premier GP"), holds an approximate 32% controlling general partner interest in, and, as a result, consolidates the financial statements of, Premier Healthcare Alliance, L.P. ("Premier LP"). The limited partners' approximate 68% ownership of Premier LP is reflected as redeemable limited partners' capital in the Company's accompanying condensed consolidated balance sheets, and the limited partners' proportionate share of income in Premier LP is reflected within net income attributable to non-controlling interest in Premier LP in the Company's accompanying condensed consolidated statements of income and within comprehensive income attributable to non-controlling interest in the accompanying condensed consolidated statements of comprehensive income. During the nine months ended March 31, 2016 , the member owners exchanged approximately 7.5 million of their Class B common units and associated Class B common stock for an equal number of Class A common stock as part of their quarterly exchange rights under an exchange agreement (the "Exchange Agreement") entered into by the member owners in connection with the completion of a series of transactions (the "Reorganization") following the consummation of the Company's initial public offering (the "IPO", and collectively with the Reorganization, the "Reorganization and IPO") on October 1, 2013 (see Note 13 - Earnings (Loss) Per Share). As a result of t he February 1, 2016 exchange, member owners’ ownership percentage of the Company’s combined Class A and Class B common stock (“Common Stock”) decreased from approximately 70% at December 31, 2015 to approximately 68% at March 31, 2016 through their ownership of Class B common stock. The ownership percentage of public investors’ ownership percentage, which may include member owners that have received shares of Class A common stock in connection with previous exchanges, increased from approximately 30% at December 31, 2015 to approximately 32% at March 31, 2016 .
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Accordingly, certain information and disclosures normally included in annual financial statements have been condensed or omitted. The accompanying condensed consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of results of operations and financial condition for the interim periods shown, including normal recurring adjustments. The Company believes that the disclosures are adequate to make the information presented not misleading and should be read in conjunction with the audited consolidated financial statements and related footnotes contained in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2015 (the "2015 Annual Report") filed with the SEC on August 26, 2015.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of the Company's condensed consolidated financial statements in accordance with GAAP requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. Significant estimates including estimates for allowances for doubtful accounts, useful lives of property and equipment, stock-based compensation, payables under tax receivable agreements, values of investments not publicly traded, the valuation allowance on deferred tax assets, uncertain income taxes, deferred revenue, future cash flows associated with asset impairments, and the allocation of purchase price are evaluated on an ongoing basis. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.
Recently Adopted Accounting Standards and Standards Not Yet Adopted	Recently Adopted Accounting Standards In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-17 Balance Sheet Classification of Deferred Taxe s as part of their simplification initiatives. The update requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The Company early adopted this standard as allowed as of December 31, 2015. The Company retroactively adjusted deferred tax assets and liabilities as they would have been reported at June 30, 2015 in accordance with ASU 2015-17 (see Note 15 - Income Taxes). In September 2015, the FASB issued ASU 2015-16 Simplifying the Accounting Measurement-Period Adjustments . Under this standard, an acquirer must recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The effect on earnings of changes in depreciation or amortization, or other income effects (if any) as a result of the change to the provisional amounts, calculated as if the accounting had been completed as of the acquisition date, must be recorded in the reporting period in which the adjustment amounts are determined rather than retrospectively. This standard also requires that the acquirer present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The Company early adopted the new standard as allowed effective January 1, 2016. The adoption of ASU 2015-16 did not result in any significant changes in the Company's result of operations or statement of position. For further information, see Note 7 - Goodwill. Recently Issued Accounting Standards Not Yet Adopted In March 2016, the FASB issued ASU No. 2016-09 Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting which is intended to simplify the accounting for employee share-based payments. The amendments in this updated guidance include changes to simplify the accounting for share-based payment transactions, including the income tax consequences, classification of such share-based awards as either equity or liabilities and classification in the statement of cash flows. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The new standard will be effective for the Company for the fiscal year beginning July 1, 2017. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of the new standard on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02 Leases (Topic 842) which is intended to increase transparency and comparability among organizations of accounting for leasing arrangements. This guidance establishes a right-of-use model that requires a lessee to record a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. Entities will be required to recognize and measure leases as of the earliest period presented using a modified retrospective approach. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The new standard will be effective for the Company for the fiscal year beginning July 1, 2019. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of the new standard on its consolidated financial statements and related disclosures. In January 2016, the FASB issued ASU No. 2016-01 Recognition and Measurement of Financial Assets and Financial Liabilities which is intended to provide users of financial statements with more useful information on the recognition, measurement, presentation, and disclosure of financial instruments. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The new standard will be effective for the Company for the fiscal year beginning July 1, 2018. Early adoption is permitted for financial statements that have not been issued. The Company is currently evaluating the impact of the adoption of the new standard on its consolidated financial statements and related disclosures. In August 2015, the FASB issued ASU 2015-15 Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements which clarifies the SEC staff’s position on presenting and measuring debt issuance costs incurred in connection with line-of-credit arrangements given the lack of guidance on this topic in ASU 2015-03 Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs. The SEC staff has announced that it would “not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement.” This standard will be effective retrospectively for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The new standard will be effective for the Company for the fiscal year beginning July 1, 2016. Early adoption is permitted for financial statements that have not been previously issued. The Company is currently evaluating the impact of the adoption of the new standard on its consolidated financial statements and related disclosures. In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory , which requires entities to measure most inventory “at the lower of cost and net realizable value,” thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market. This guidance will not apply to inventories that are measured by using either the last-in, first-out method or the retail inventory method. The new standard will be effective prospectively for annual periods beginning after December 15, 2016, and interim periods therein. The new standard will be effective for the Company for the fiscal year beginning July 1, 2017. Early adoption is permitted. Upon transition, entities must disclose the nature of and reason for the accounting change. The Company is currently evaluating the impact of the adoption of the new standard on its consolidated financial statements and related disclosures. In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis , which effectively eliminates the presumption that a general partner should consolidate a limited partnership, modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIE"s) or voting interest entities, and affects the consolidation analysis of reporting entities that are involved with VIEs (particularly those that have fee arrangements and related party relationships). In some cases, consolidation conclusions will change under the new guidance and, in other cases, a reporting entity will provide additional disclosures if an entity that currently is not considered a VIE is considered a VIE under the new guidance. The new standard will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2015 and early adoption is permitted. The new standard allows for either full retrospective or modified retrospective adoption. The new standard will be effective for the Company for the fiscal year beginning July 1, 2016. The Company has completed its preliminary evaluation and believes there is no impact from the adoption of the new standard on its consolidated financial statements other than providing additional disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , which will supersede nearly all existing revenue recognition guidance. The new standard requires revenue to be recognized 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. The new standard also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The new standard allows for either full retrospective or modified retrospective adoption. The FASB subsequently issued an amendment in ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , in August 2015 to defer the effective date of the new standard for all entities by one year. The new standard, as amended, will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and early adoption as of the original effective date for public entities will be permitted. ASU 2014-09, as amended, will be effective for the Company for the fiscal year beginning July 1, 2018. The FASB issued another amendment in ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations , in March 2016 related to a third party providing goods or services to a customer. When another party is involved in providing goods or services to a customer, an entity is required to determine whether the nature of its promise is to provide the specified good or service itself, the entity acts as a principal. If an entity arranges for the good or service to be provided by a third party, the entity acts as an agent. The amendment requires principals to recognize revenue for the gross amount and agents to recognize revenue for the amount of any fee or commission it expects to be entitled. The amendment will be effective with ASU 2014-09. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing , which amends specific aspects of ASU 2014-09, Revenue from Contracts with Customers, including how to identify performance obligations and guidance related to licensing implementation. This amendment provides guidance on determining whether an entity's promise to grant a license provides a customer with either a right to use the entity's intellectual property or a right to access the entity's intellectual property. The amendment will be effective with ASU 2014-09. The Company is currently evaluating the transition method that will be elected as well as the impact of the adoption of ASU 2014-09, as amended, on its consolidated financial statements and related disclosures. The Company is also evaluating the impact of the deferral of the effective date on its plans for adopting the new standard.

(b) Weighted average number of common shares used for basic earnings (loss) per share excludes weighted average shares of non-vested stock options, non-vested restricted stock, non-vested performance share awards and Class B shares outstanding for the three and nine months ended March 31, 2016 and 2015, respectively. (c) For the three months ended March 31, 2015 , the effect of 151 , 380 and 617 stock options, restricted stock units, and performance share awards, respectively, and for the nine months ended March 31, 2015, 4 , 319 , and 522 stock options, restricted stock units, and performance share awards, respectively, were excluded from the diluted weighted average shares outstanding due to the net loss sustained for the respective periods. Further, 106,659 Class B common units exchangeable for Class A common shares was excluded from the dilutive weighted average shares outstanding because to do so would have been anti-dilutive for the period presented.

Key Assumptions Used for Determining the Fair Value of Stock Options Granted	The Company estimates the fair value of each stock option on the date of grant using a Black-Scholes option-pricing model, applying the following assumptions and amortizes expense over the option's vesting period using the straight-line attribution approach: March 31, 2016 2015 Expected life (1) 6 years 6 years Expected dividend (2) — — Expected volatility (3) 32.70% - 33.50% 36.20% - 39.50% Risk-free interest rate (4) 1.37% - 1.82% 1.66% - 1.84% Weighted average option grant date fair value $11.28 - $12.40 $12.82 - $13.77 (1) The six -year expected life (estimated period of time outstanding) of stock options granted was estimated using the "Simplified Method" which utilizes the midpoint between the vesting date and the end of the contractual term. This method was utilized for the stock options due to the lack of historical exercise behavior of Premier's employees. (2) No dividends are expected to be paid over the contractual term of the stock options granted, resulting in the use of a zero expected dividend rate. (3) The expected volatility rate is based on the observed historical volatilities of comparable companies. (4) The risk-free interest rate was interpolated from the five -year and seven -year United States Treasury constant maturity market yield as of the date of the grant.

(b) Represents legal, accounting and other expenses directly related to strategic and financial restructuring expenses. (c) Represents non-cash employee stock based compensation expense and $0.1 million and $0.3 million stock purchase plan expense in the three and nine months ended March 31, 2016 , respectively. (d) Represents implementation and other costs associated with the implementation of a new enterprise resource planning ("ERP") system. (e) Represents adjustment to tax receivable agreement liability for a 1% decrease in the North Carolina state income tax rate during the nine months ended March 31, 2016 and adjustment to tax receivable agreements liability due to impact of departed member owners during the three months ended March 31, 2015 . (f) Represents non-cash adjustment to deferred revenue of acquired entities. Business combination accounting rules require the Company to record a deferred revenue liability at its fair value only if the acquired deferred revenue represents a legal performance obligation assumed by the acquirer. The fair value is based on direct and indirect incremental costs of providing the services plus a normal profit margin. Generally, this results in a reduction to the purchased deferred revenue balance, which was based on upfront fees associated with software license updates and product support contracts assumed in connection with acquisitions. Because these support contracts are typically one year in duration, our GAAP revenues for the one year period subsequent to the acquisition of a business do not reflect the full amount of support revenues on these assumed support contracts that would have otherwise been recorded by the acquired entity. The Non-GAAP adjustment to software license updates and product support revenues is intended to include, and thus reflect, the full amount of such revenues. (g) Represents equity in net income of unconsolidated affiliates primarily generated by the Company's 50% ownership interest in Innovatix, all of which is included in the supply chain services segment
