ORGANIZATION AND BASIS OF PRESENTATION	'
	ORGANIZATION AND BASIS OF PRESENTATION
	Organization
	Premier, Inc. ("Premier," the "Company" or "We") 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 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 business 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 its 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 three main categories: cost management, quality and safety and population health management. This segment also includes the Company's technology-enabled performance improvement collaboratives, advisory services and insurance services.
	Basis of Presentation and Consolidation
	The Company, through its wholly owned subsidiary, Premier Services, LLC ("Premier GP"), holds a 22% controlling general partner interest in and, as a result, consolidates the financial statements of Premier Healthcare Alliance, L.P. ("Premier LP"). The limited partners' 78% ownership of Premier LP is reflected as redeemable limited partners' capital in the Company's consolidated balance sheets, and their proportionate share of income in Premier LP is reflected within net income attributable to noncontrolling interest in Premier LP in the Company's consolidated statements of income and within comprehensive income attributable to noncontrolling interest in the consolidated statements of comprehensive income.
	After the completion of a series of transactions following the consummation of the initial public offering ("IPO"), referred to as the "Reorganization," Premier Healthcare Solutions, Inc. ("PHSI") became a consolidated subsidiary of the Company. PHSI is considered the predecessor of the Company for accounting purposes, and accordingly, PHSI's consolidated financial statements are the Company's historical financial statements, for periods prior to October 1, 2013. The historical consolidated financial statements of PHSI are reflected herein based on PHSI's historical ownership interests of Premier LP and its consolidated subsidiaries. Refer to Note 2 for further information related to the IPO and the Reorganization.
	The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Accordingly, the 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 periods shown, including normal recurring adjustments.
	The Company has reclassified certain prior period amounts to be consistent with the current period presentation in the accompanying consolidated financial statements and corrected certain classification differences in the consolidated statements of cash flows. For the year ended June 30, 2013, the Company has presented $3 million in costs associated with the IPO as financing rather than operating activities.
	Use of Estimates in the Preparation of Financial Statements
	The preparation of the Company's consolidated financial statements 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. Estimates are evaluated on an ongoing basis, including 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 and the fair value of purchased intangible assets and goodwill. 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.

Initial Public Offering and Reorganization [Abstract]	'
INITIAL PUBLIC OFFERING AND REORGANIZATION	'
	INITIAL PUBLIC OFFERING AND REORGANIZATION
	Initial Public Offering
	On October 1, 2013, Premier consummated its IPO of 32,374,751 shares of its Class A common stock, at a price of $27.00 per share, raising net proceeds of approximately $821.7 million after underwriting discounts and commissions, but before expenses.
	Premier used approximately (i) $543.9 million of the net proceeds from the IPO to acquire 21,428,571 Class B common units from the member owners, (ii) $30.1 million of the net proceeds to acquire 1,184,882 Class B common units from PHSI and (iii) $247.7 million of the net proceeds to acquire 9,761,298 newly issued Class A common units of Premier LP, or the Class A common units, from Premier LP, in each case for a price per unit equal to the price paid per share of Class A common stock by the underwriters to Premier in connection with the IPO. All Class B common units purchased by Premier with the net proceeds from the IPO automatically converted to Class A common units, pursuant to the terms of the Amended and Restated Limited Partnership Agreement of Premier LP (the "LP Agreement"), and were contributed by Premier to Premier GP.
	Reorganization
	On October 1, 2013 (the "Effective Date"), Premier consummated the Reorganization. In connection with the Reorganization and IPO, immediately following the Effective Date, all of Premier LP's limited partners that approved the Reorganization received an amount of Class B common units and capital account balances in Premier LP equal to their percentage interests and capital account balances in Premier LP immediately preceding the Reorganization. Additionally, immediately following the Effective Date, all of the stockholders (consisting of member owners) of PHSI that approved the Reorganization contributed their PHSI common stock to Premier LP in exchange for additional Class B common units based on such stockholder's percentage interest in the fair market valuation of PHSI and Premier LP prior to the Reorganization. As a result of the foregoing contributions, PHSI became a wholly owned subsidiary of Premier LP.
	In connection with the Reorganization, the member owners purchased from Premier 112,607,832 shares of Class B common stock, for par value, $0.000001 per share, which number of shares of Class B common stock equaled the number of Class B common units held by the member owners immediately following the IPO, pursuant to a stock purchase agreement.
	Below is a summary of the principal documents that effected the Reorganization and define and regulate the governance and control relationships among Premier, Premier LP and the member owners after the completion of the Reorganization and IPO.
	LP Agreement
	In connection with the Reorganization and IPO, pursuant to the LP Agreement, Premier GP became the general partner of Premier LP. As the general partner of Premier LP, Premier GP generally controls the day-to-day business affairs and decision-making of Premier LP without the approval of any other partner, subject to certain limited partner approval rights. As the sole member of Premier GP, Premier is responsible for all operational and administrative decisions of Premier LP. In accordance with the LP Agreement, subject to applicable law or regulation and the terms of Premier LP's financing agreements, Premier GP will cause Premier LP to make quarterly distributions out of its estimated taxable net income to Premier GP and to the holders of Class B common units as a class in an aggregate amount equal to Premier LP's total taxable income other than net profit attributable to dispositions not in the ordinary course of business for each such quarter multiplied by the effective combined federal, state and local income tax rate then payable by Premier to facilitate payment by each Premier LP partner of taxes, if required, on its share of taxable income of Premier LP. In addition, in accordance with the LP Agreement, Premier GP may cause Premier LP to make additional distributions to Premier GP and to the holders of Class B common units as a class in proportion to their respective number of units, subject to any applicable restrictions under Premier LP's financing agreements or applicable law. Premier GP will distribute any amounts it receives from Premier LP to Premier, which Premier will use to (i) pay applicable taxes, (ii) meet its obligations under the tax receivable agreements and (iii) meet its obligations to the member owners under the exchange agreement if they elect to convert their Class B common units for shares of its Class A common stock and Premier elects to pay some or all of the consideration to such member owners in cash.
	In the event that a limited partner of Premier LP holding Class B common units not yet eligible to be exchanged for shares of Premier's Class A common stock pursuant to the terms of the exchange agreement (i) ceases to participate in Premier's GPO programs, (ii) ceases to be a limited partner of Premier LP (except as a result of a permitted transfer of its Class B common units), (iii) ceases to be a party to a GPO participation agreement (subject to certain limited exceptions) or (iv) becomes a related entity of, or affiliated with, a competing business of Premier LP, in each case, Premier LP will have the option to redeem all of such limited partner's Class B common units not yet eligible to be exchanged at a purchase price set forth in the LP Agreement. In addition, the limited partner will be required to exchange all Class B common units eligible to be exchanged on the next exchange date following the date of the applicable termination event described above. There were no exchanges during the period from October 1, 2013 through June 30, 2014.
	Voting Trust Agreement
	Additionally, in connection with the Reorganization and IPO, Premier's member owners entered into a voting trust agreement, which became effective upon the completion of the Reorganization and IPO and pursuant to which the member owners contributed their Class B common stock into Premier Trust, under which Wells Fargo Delaware Trust Company, N.A., as trustee, acts on behalf of the member owners for purposes of voting their shares of Class B common stock. As a result of the voting trust agreement, the member owners retain beneficial ownership of the Class B common stock, while the trustee is the legal owner of such equity. Pursuant to the voting trust agreement, the trustee will vote all of the member owners' Class B common stock as a block in the manner determined by the plurality of the votes received by the trustee from the member owners for the election of directors to serve on our board of directors, and by a majority of the votes received by the trustee from the member owners for all other matters.
	Exchange Agreement
	In connection with the Reorganization and IPO, Premier, Premier LP and the member owners entered into an exchange agreement which became effective upon the completion of the Reorganization and IPO. Pursuant to the terms of the exchange agreement, subject to certain restrictions, commencing on October 31, 2014, and during each year thereafter, each member owner will have the cumulative right to exchange up to one-seventh of its initial allocation of Class B common units, as well as any additional Class B common units purchased by such member owner pursuant to certain rights of first refusal (discussed below), for shares of Class A common stock (on a one-for-one basis subject to customary adjustments for subdivisions or combinations by split, reverse split, distribution, reclassification, recapitalization or otherwise), cash or a combination of both, the form of consideration to be at the discretion of Premier's audit committee (or another committee of independent directors). This exchange right can be exercised on a quarterly basis (subject to certain restrictions contained in the registration rights agreement described below) and is subject to rights of first refusal in favor of the other holders of Class B common units and Premier LP. For each Class B common unit that is exchanged pursuant to the exchange agreement, the member owner will also surrender one corresponding share of our Class B common stock, which will automatically be retired.
	Registration Rights Agreement
	In connection with the Reorganization and IPO, Premier and the member owners entered into a registration rights agreement which became effective upon the completion of the Reorganization and IPO. Pursuant to the terms of the registration rights agreement, as soon as practicable from the date that is 12 full calendar months after the completion of the Reorganization and IPO, Premier must use all reasonable efforts to cause a resale shelf registration statement to become effective for resales from time to time of its Class A common stock that may be issued to the member owners in exchange for their Class B common units pursuant to the exchange agreement, subject to various restrictions. Subject to certain exceptions, Premier will use reasonable efforts to keep the resale shelf registration statement effective for seven years. In addition, Premier will undertake to conduct an annual company-directed underwritten public offering to allow the member owners to resell Class A common stock and, at Premier's election, to permit it to sell primary shares, following the first quarterly exchange date of each of the first three years during which the member owners have the right to exchange their Class B common units for shares of Class A common stock. Premier will not be required to conduct a company-directed underwritten public offering unless the number of shares of Class A common stock requested by the member owners (and any third parties) to be registered in the applicable company-directed underwritten public offering constitutes the equivalent of at least 3.5% of the aggregate number of Class A common units and Class B common units, or, collectively, the common units, outstanding. If the offering minimum has not been met, Premier will either proceed with the company-directed underwritten public offering (such decision being in Premier's sole discretion) or notify the member owners that Premier will abandon the offering. After the third year during which member owners have the right to exchange their Class B common units for shares of Premier's Class A common stock, Premier may elect to conduct a company-directed underwritten public offering in any subsequent year. Premier, as well as the member owners, and third parties, will be subject to customary prohibitions on sale prior to and for 60 days following any company-directed underwritten public offering. The registration rights agreement also grants the member owners certain "piggyback" registration rights with respect to other registrations of Class A common stock.
	Tax Receivable Agreements
	In connection with the Reorganization and IPO, Premier entered into a tax receivable agreements with the member owners which became effective upon the completion of the Reorganization and IPO. Pursuant to the terms of the tax receivable agreements, Premier has agreed to pay to the member owners for as long as the member owner remains a limited partner, generally over a 15-year period (under current law), 85% of the amount of cash savings, if any, in U.S. federal, foreign, state and local income and franchise tax that Premier actually realizes (or is deemed to realize, in the case of payments required to be made upon certain occurrences under such tax receivable agreements) as a result of the increases in tax basis resulting from the initial sale of Class B common units by the member owners in connection with the Reorganization, as well as subsequent exchanges by such member owners pursuant to the exchange agreement, and of certain other tax benefits related to Premier entering into the tax receivable agreements, including tax benefits attributable to payments under the tax receivable agreements.
	GPO Participation Agreement
	In connection with the Reorganization and IPO, Premier's member owners entered into GPO participation agreements with Premier LP which became effective upon the completion of the Reorganization and IPO. Pursuant to the terms of its GPO participation agreement, each member owner will receive cash sharebacks, or revenue share, from Premier LP equal to 30% of all gross administrative fees collected by Premier LP based upon purchasing by such member owner's acute and alternate site providers and other eligible non-healthcare organizations that are owned, leased or managed by, or affiliated with, each such member owner, or member facilities, through Premier's GPO supplier contracts. In addition, Premier's two largest regional GPO member owners, which represented approximately 16% of Premier LP's gross administrative fees revenue for fiscal year 2014, will each remit all gross administrative fees collected by such member owner based upon purchasing by such member owner's member facilities through the member owner's own GPO supplier contracts and receive revenue share from Premier LP equal to 30% of such gross administrative fees remitted to Premier LP. Subject to certain termination rights, these GPO participation agreements will be for an initial five-year term, although Premier LP's two largest regional GPO member owners have entered into agreements with seven-year terms.
	The terms of the GPO participation agreements vary as a result of provisions in Premier's existing arrangements with member owners that conflict with the terms of the GPO participation agreement and which by the express terms of the GPO participation agreement are incorporated by reference and deemed controlling and will continue to remain in effect. In certain other instances, Premier LP and member owners have entered into GPO participation agreements with certain terms that vary from the standard form, which were approved by the member agreement review committee of Premier's board of directors, based upon regulatory constraints, pending merger and acquisition activity or other circumstances affecting those member owners.
	Effects of the Reorganization
	Immediately following the consummation of the Reorganization and IPO:
	•	Premier became the sole member of Premier GP and Premier GP became the general partner of Premier LP. Through Premier GP, Premier exercises indirect control over the business operated by Premier LP, subject to certain limited partner approval rights. Premier GP has no employees and acts solely through its board of managers and appointed officers in directing the affairs of Premier LP;
	•	the member owners held 112,607,832 shares of Class B common stock and 112,607,832 Class B common units;
	•	Premier GP held 32,374,751 Class A common units;
	•	through their holdings of Class B common stock, the member owners had approximately 78% of the voting power in Premier;
	•	the investors in the IPO collectively owned all of Premier's outstanding shares of Class A common stock and collectively had approximately 22% of the voting power in Premier; and
	•	Premier LP was the operating partnership and parent company to all of Premier's other operating subsidiaries, including Premier Supply Chain Improvement, Inc. ("PSCI") and PHSI.
	Any newly admitted Premier LP limited partners will also become parties to the exchange agreement, the registration rights agreement, the voting trust agreement and the tax receivable agreements, in each case on the same terms and conditions as the then existing member owners (except that any Class B common units acquired by such newly admitted Premier LP limited partners will not be subject to the seven-year vesting schedule set forth in the LP Agreement and the exchange agreement). Any newly admitted Premier LP limited partner will also enter into a GPO participation agreement with Premier LP.
	Impact of the Reorganization
	The impact of the Reorganization gave effect to:
	•	(i) the issuance of 32,374,751 shares of Class A common stock in the IPO, or approximately 22% of the Class A common stock and Class B common stock, collectively, outstanding after the Reorganization and IPO, at an IPO price of $27.00 per share and the use of the net proceeds therefrom to purchase (A) Class A common units from Premier LP, (B) Class B common units from PHSI and (C) Class B common units from Premier's member owners, (ii) the entry by Premier LP, Premier GP and the member owners into the LP Agreement and (iii) the issuance of 112,607,832 shares of Class B common stock to the member owners;
	•	the change from the 99% noncontrolling interest held by the limited partners of Premier LP prior to the Reorganization to the approximately 78% noncontrolling interest held by the limited partners of Premier LP subsequent to the Reorganization and IPO;
	•	the change in the allocation of Premier LP's income from 1% of operating income and 5% of investment income to PHSI prior to the Reorganization and IPO to approximately 22% of Premier LP's income to Premier (indirectly through Premier GP) subsequent to the Reorganization and IPO as the result of the modified income allocation provisions of the LP Agreement and Premier's purchase of approximately 22% of the common units;
	•	adjustments to reflect redeemable limited partners' capital at the greater of the book value or redemption amount per the LP Agreement;
	•	adjustments that give effect to the tax receivable agreements, including the effects of the increase in the tax basis of Premier LP's assets resulting from Premier's purchase of Class B common units from the member owners; and
	•	estimated payments due to member owners pursuant to the tax receivable agreements equal to 85% of the amount of cash savings, if any, in U.S. federal, foreign, state and local income and franchise tax that Premier actually realizes (or is deemed to realize in the case of certain payments required to be made upon certain occurrences under such tax receivable agreements) as a result of the increases in the tax basis of Premier LP's assets resulting from Premier's purchase of Class B common units from the member owners and of certain other tax benefits related to Premier entering into the tax receivable agreements.
	Premier accounted for the Reorganization as a non-substantive transaction in a manner similar to a transaction between entities under common control pursuant to Accounting Standards Codification Topic 805, Business Combinations. Accordingly, after the Reorganization, the assets and liabilities of Premier are reflected at their carryover basis.
	The following table presents the adjustments to the balance sheet upon the consummation of the Reorganization and IPO at October 1, 2013 (in thousands):

	-1	Reflects net effect on cash and cash equivalents of the receipt of gross proceeds from the IPO of $874.1 million (with an IPO price of $27.00 per share of Class A common stock) and the purchase of units from the member owners described above, as follows (in thousands):
Gross proceeds from the IPO	$	874,118
Underwriting discounts, commissions and other expenses	(52,447		)
Purchases of Class B common units from the member owners	(543,857		)
Net cash proceeds from IPO	$	277,814
-2	Reflects the reduction of prepaid expenses related to the IPO, with an offset to the proceeds of the IPO in additional paid-in capital.
-3	Premier LP intends to have in effect an election under Section 754 of the Internal Revenue Code of 1986, as amended, or the Code, and comparable elections under state and local tax law, such that the initial sale of Class B common units by PHSI and the member owners will result in adjustments to the tax basis of the assets of Premier LP. These increases in tax basis increase (for tax purposes) the depreciation and amortization deductions by Premier LP, and therefore, reduce the amount of income tax that Premier would otherwise be required to pay in the future. In connection with the Reorganization and IPO, Premier has entered into a tax receivable agreements with the member owners which became effective upon the completion of the Reorganization and IPO, pursuant to which Premier agreed to pay to the member owners, generally over a 15-year period (under current law), 85% of the amount of cash savings, if any, in U.S. federal, foreign, state and local and franchise income tax that Premier actually realizes (or is deemed to realize, in the case of payments required to be made upon certain occurrences under such tax receivable agreements) as a result of the increases in tax basis resulting from the sale or exchange of Class B common units by the member owners. The adjustments give effect to the Section 754 election and the tax receivable agreements based on the following assumptions:
•	The increase in deferred tax assets representing the income tax effects of the increases in the tax basis as a result of Premier LP's election under Section 754 of the Code in connection with the initial sale of Class B common units described above. This adjustment is calculated based on an effective income tax rate for Premier of approximately 39%, which includes a provision for U.S. federal income taxes and assumes (i) Premier's statutory rates apportioned to each state and local tax jurisdiction, (ii) that there are no material changes in the relevant tax law, and (iii) that Premier earns sufficient taxable income in each year to realize the full tax benefit of the amortization of its assets.
•	Premier determined the adjustments in connection with the Section 754 election by first calculating the excess of each selling member owner's and PHSI's selling price over such person's share of Premier LP's tax basis in its assets attributable to the Class B common units sold to Premier. Premier then allocated the aggregate excess among Premier LP's assets following applicable tax regulations governing adjustments that result from the Section 754 election. Premier determined each selling member owner's share of the tax basis in Premier LP's assets attributable to the Class B common units sold to Premier by multiplying the member owner's tax capital account balance as of the date of sale as maintained in Premier LP's books and records by a fraction, the numerator of which was the number of Class B common units sold to Premier, and the denominator of which was the number of Class B common units held by the selling member owner immediately prior to the sale. For purposes of the calculation, the selling price per Class B common unit was equal to the net price paid per share of the Class A common stock by the underwriters to Premier in the IPO. The adjustments increased Premier LP's basis in its assets (for tax purposes), and Premier calculates the amount of depreciation, amortization and other deductions to which it is entitled as a result of these adjustments. Premier then calculates Premier's tax liability with and without the deductions attributable to these adjustments, assuming that Premier earns sufficient taxable income in each year to realize the full benefit of the deductions. Premier computed the estimated tax benefit attributable to the election as the excess of Premier's tax liability as so computed without the deductions over Premier's tax liability as so computed with the deductions. Additionally, the tax receivable agreements payments give rise to adjustments that result in Premier LP becoming entitled to additional deductions, and the calculation of Premier's liability under the tax receivable agreements take these adjustments and additional resulting deductions into account.
•	Premier LP's election under Section 754 of the Code is at the discretion of Premier LP and is not subject to review or approval by the IRS or other tax authorities. The computation of the adjustments resulting from the Section 754 election and Premier's tax liability is subject to audit by the IRS and other tax authorities in the same manner as all other items reported on income tax returns.
•	Upon the Reorganization and IPO, the cumulative adjustments of $186.1 million, of which $7.0 million was expected to be paid over the next 12 months, and was reflected as a current liability with the remaining balance classified as a long-term liability, to reflect a liability equal to 85% of the estimated realizable tax benefit resulting from the increase in tax basis due to Premier LP's Section 754 election in connection with the initial sale by the member owners of the Class B common units described above as an increase to payable pursuant to the tax receivable agreements.
•	Deferred tax assets are measured based on the difference in tax basis of Premier's investment in Premier LP as compared to its GAAP carrying value and include the change in allocations in connection with the Reorganization. The adjustments related to Premier LP's Section 754 election described above are a component of Premier's tax basis in Premier LP.
Pursuant to the terms of the exchange agreement, the member owners and new limited partners admitted to Premier LP following the completion of the IPO may subsequently exchange Class B common units in Premier LP for shares of Premier's Class A common stock, cash or a combination of both. Any subsequent exchanges of Class B common units for shares of Premier's Class A common stock pursuant to the exchange agreement may result in increases in the tax basis of the tangible and intangible assets of Premier LP (85% of the realized tax benefits from which will be due to the limited partners and recorded as an additional payable pursuant to the tax receivable agreements) that otherwise would not have been available. These subsequent exchanges have not been reflected in the consolidated financial statements.
-4	Reflects the increase in the noncontrolling interest held by the limited partners in Premier LP resulting from the net proceeds from the IPO used to purchase Class A common units from Premier LP of $247.7 million and Class B common units from PHSI of $30.1 million, and the contribution of the common stock of PHSI in connection with the Reorganization of $76.9 million. This is offset by an adjustment of $131.0 million to reflect the approximately 78% controlling interest held by the redeemable limited partners of Premier LP subsequent to the Reorganization and IPO, which is reflected in redeemable limited partners' capital on the unaudited consolidated balance sheets. Immediately following the effective date of the LP Agreement, all of Premier LP's limited partners that approved the Reorganization received Class B common units and capital account balances in Premier LP equal to their percentage interests and capital account balances in Premier LP immediately preceding the Reorganization. Premier used a portion of the net proceeds from the IPO to purchase (i) Class A common units, (ii) Class B common units from PHSI and (iii) Class B common units from the member owners, resulting in a reduction in the noncontrolling interest attributable to the limited partners from 99% to approximately 78%.
Reflects the increase in redeemable limited partners' capital of $2,575.5 million to record the balance at the redemption amount, which represents the greater of the book value or redemption amount per the LP Agreement, at the date of the Reorganization. This results in an offsetting decrease in retained earnings of $50.1 million, followed by an offsetting decrease in additional paid-in-capital of $173.7 million and with a final offsetting increase in accumulated deficit of $2,351.7 million.
-5	Reflects (i) the exchange of the existing PHSI shares of common stock, common stock subscribed and related subscriptions receivable for Class B common units, (ii) the issuance of Class B common stock in connection with the Reorganization and (iii) the issuance of Class A common stock in connection with the IPO.
-6	Reflects the impact of the adjustments in notes (1), (2), (3), (4) and (5) above to additional paid-in capital:
•	an increase of $96.9 million due to an increase in deferred tax assets described in note (3) of $283.0 million offset by an increase in payables pursuant to the tax receivable agreements of $186.1 million;
•	an increase of $821.7 million from the net proceeds from the IPO less the par value of the shares of Class A common stock sold in the IPO of $0.3 million and less prepaid offering expenses of $5.9 million;
•	a decrease of $767.5 million to reflect the difference between the consideration paid to acquire the Class A and B common units and the adjustment to the carrying value of the noncontrolling interest described in note (4) above; and
•	a decrease in the remaining balance of additional paid-in-capital related to the increase in redeemable limited partners' capital to its redemption value, as described in note (4) above.
-7	Reflects the decrease in retained earnings and increase in accumulated deficit related to the increase in redeemable limited partners' capital to its redemption value, as described in note (4) above.
In addition, following the completion of the Reorganization and the IPO:
•	Premier LP became contractually required under the GPO participation agreements to pay each member owner revenue share from Premier LP equal to 30% of all gross administrative fees collected by Premier LP based upon purchasing by such member owner's member facilities through Premier LP's GPO supplier contracts. Historically, Premier LP did not generally have a contractual requirement to pay revenue share to member owners participating in its GPO programs, but paid semi-annual distributions of partnership income.
•	Premier records redeemable limited partners' capital at redemption value, which represents the greater of the book value or redemption amount per the LP Agreement, at the reporting date.
•	Premier became subject to additional U.S. federal, state and local income taxes with respect to its additional allocable share of any taxable income of Premier LP.
•	Noncontrolling interest in Premier LP decreased from 99% to approximately 78%.

SIGNIFICANT ACCOUNTING POLICIES	'
	SIGNIFICANT ACCOUNTING POLICIES
	Cash and Cash Equivalents
	Cash and cash equivalents include cash and highly liquid investments with remaining maturities of three months or less at the time of acquisition.
	Concentration of Credit Risk and Allowance for Doubtful Accounts
	Financial instruments that subject the Company to potential concentrations of credit risk consist primarily of the Company's receivables and marketable securities. Receivables consist primarily of amounts due from hospital and healthcare system members for services and products. The Company maintains an allowance for doubtful accounts. This allowance is an estimate and is regularly evaluated by the Company for adequacy by taking into consideration factors such as past experience, credit quality of the member base, age of the receivable balances, both individually and in the aggregate, and current economic conditions that may affect a member's ability to pay. Provisions for the allowance for doubtful accounts attributed to bad debt are recorded in selling, general and administrative expenses in the accompanying consolidated statements of income.
	Fair Value of Financial Instruments
	The fair value of an asset or liability is based on the assumptions that market participants would use in pricing the asset or liability. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value. The Company follows a three-tiered fair value hierarchy when determining the inputs to valuation techniques. The fair value hierarchy prioritizes the inputs to valuation techniques into three broad levels in order to maximize the use of observable inputs and minimize the use of unobservable inputs. The levels of the fair value hierarchy are as follows:
	Level 1: consists of financial instruments whose values are based on quoted market prices for identical financial instruments in an active market;
	Level 2: consists of financial instruments whose values are determined using models or other valuation methodologies that utilize inputs that are observable either directly or indirectly, including (i) quoted prices for similar assets or liabilities in active markets, (ii) quoted prices for identical or similar assets or liabilities in markets that are not active, (iii) pricing models whose inputs are observable for substantially the full term of the financial instrument and (iv) pricing models whose inputs are derived principally from or corroborated by observable market data through correlation or other means for substantially the full term of the financial instrument;
	Level 3: consists of financial instruments whose values are determined using pricing models that utilize significant inputs that are primarily unobservable, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
	Marketable Securities
	The Company invests its excess cash in commercial paper, corporate debt securities, government securities and other securities with maturities generally ranging from three months to five years from the date of purchase. Marketable securities, classified as available-for-sale, are carried at fair market value, with the unrealized gains and losses on such investments reported in comprehensive income as a separate component of stockholders' (deficit) equity or redeemable limited partners' capital as appropriate. Realized gains and losses, and other-than-temporary declines in investments, are included in other income, net in the accompanying consolidated statements of income. The Company uses the specific-identification method to determine the cost of securities sold. The Company does not hold publicly traded equity investments.
	Inventories
	Inventories consisting of medical products and other non-pharmaceutical products are stated at the lower of cost or market on an average cost basis. Inventories consisting of pharmaceuticals and pharmaceutical-related products are stated at the lower of cost or market on a first-in, first-out basis. Management determines the inventory reserve by regularly reviewing and evaluating individual inventory items. Inventory is written off when deemed obsolete or unsellable by management.
	Investments
	The Company uses the cost method to account for investments in businesses that are not publicly traded and for which the Company does not control or have the ability to exercise significant influence over operating and financial policies. In accordance with the cost method, these investments are recorded at the lower of cost or fair value, as appropriate.
	Investments held by the Company in businesses that are not publicly traded and for which the Company has the ability to exercise significant influence over operating and financial management are accounted for under the equity method. In accordance with the equity method, these investments are originally recorded at cost and are adjusted for the Company's proportionate share of earnings, losses and distributions.
	The Company assesses and records impairment losses when events and circumstances indicate the investments might be impaired. Gains and losses are recognized when realized.
	Property and Equipment, Net
	Property and equipment is stated at cost. Depreciation is calculated based upon estimated useful lives ranging from three to five years, using the straight-line method. Leasehold improvements are depreciated over the shorter of the estimated useful life of the asset or the lease term.
	Software Development Costs
	Costs to develop internal use computer software during the application development stage are capitalized. Internal use capitalized software costs are included in property and equipment, net in the accompanying consolidated balance sheets. Capitalized costs are amortized on a straight-line basis over the estimated useful lives of the related software applications of up to five years and amortization is included in cost of revenue in the accompanying consolidated statements of income. The Company capitalized costs related to software developed for internal use of $41.1 million, $31.3 million and $28.7 million during the years ended June 30, 2014, 2013 and 2012, respectively.
	Restricted Cash
	Restricted cash of $5.0 million at both June 30, 2014 and 2013 represents cash equivalents held in a trust by Wells Fargo Bank, National Association in favor of the Vermont Department of Financial Regulation (the "Department") on behalf of Premier Insurance Exchange, Risk Retention Group ("PRx"), an entity in which the Company has an equity investment (see Note 8). The Department has the right to withdraw the funds from the trust at any time it is deemed necessary for PRx to meet policyholder claim obligations or other statutory requirements.
	Deferred Compensation Plan Assets and Related Liabilities
	The Company maintains a non-qualified deferred compensation plan for the benefit of eligible employees. This plan is designed to permit employee deferrals in excess of certain tax limits and provides for discretionary employer contributions in excess of the tax limits applicable to the Company's 401(k) plan.
	Company assets designated to pay benefits under the plan are held by a rabbi trust and are subject to the general creditors of the Company. The amounts deferred are invested in assets at the direction of the employee.
	The assets, classified as trading securities, and liabilities of the rabbi trust are recorded at fair value and are accounted for as assets and liabilities of the Company. The assets of the rabbi trust are used to fund the deferred compensation liabilities owed to current and former employees. The deferred compensation plan contains both current and non-current assets. The current portion of the deferred compensation plan assets is comprised of estimated amounts to be paid within one year to departed participants following separation from the Company. The estimated current portion, totaling $0.3 million and $0.4 million at June 30, 2014 and 2013, respectively, is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets. The corresponding current portion of deferred compensation plan liabilities is included in other current liabilities in the accompanying consolidated balance sheets at June 30, 2014 and 2013. The non-current portion of the deferred compensation plan assets, totaling $32.9 million and $24.1 million at June 30, 2014 and 2013, respectively, is included in other assets in the accompanying consolidated balance sheets. The corresponding non-current portion of deferred compensation plan liabilities is included in long-term liabilities in the accompanying consolidated balance sheets at June 30, 2014 and 2013. Unrealized gains of $2.0 million on plan assets as of June 30, 2014 are included in other income (expense), net in the accompanying consolidated statements of income. The corresponding expense of $2.0 million is included in selling, general and administrative expense in the accompanying consolidated statements of income. Unrealized gains and losses on plan assets for the years ended June 30, 2013 and 2012 were insignificant.
	Goodwill
	Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill is not amortized. The Company performs its annual goodwill impairment testing on the first day of the last fiscal quarter of its fiscal year unless impairment indicators are present which could require an interim impairment test.
	Under the accounting rules, the Company can elect to perform a qualitative assessment to determine if an impairment is more likely than not to have occurred. This qualitative assessment requires an evaluation of any excess of fair value over the carrying value for a reporting unit and significant judgment regarding potential changes in valuation inputs, including a review of the Company's most recent long-range projections, analysis of operating results versus the prior year, changes in market values, changes in discount rates and changes in terminal growth rate assumptions. If it is determined that an impairment is more likely than not to exist, then we are required to perform a quantitative assessment to determine whether or not goodwill is impaired and to measure the amount of goodwill impairment, if any.
	Goodwill impairment is determined using a two-step process. The first step involves a comparison of the estimated fair value of each of our reporting units to its carrying amount, including goodwill. In performing the first step, we determine the fair value of a reporting unit using a discounted cash flow analysis that is corroborated by a market-based approach. Determining fair value requires the exercise of significant judgment, including judgment about appropriate discount rates, perpetual growth rates and the amount and timing of expected future cash flows. The cash flows employed in the discounted cash flow analyses are based on our most recent budget and long-term forecast. The discount rates used in the discounted cash flow analyses are intended to reflect the risks inherent in the future cash flows of the respective reporting units. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired and the second step of the impairment test is not necessary.
	If the carrying amount of a reporting unit exceeds its estimated fair value, then the second step of the goodwill impairment test must be performed. The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with its goodwill carrying amount to measure the amount of impairment, if any. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. In other words, the estimated fair value of the reporting unit is allocated to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit was the purchase price paid. If the carrying amount of the reporting unit's goodwill exceeds the implied fair value of that goodwill, an impairment charge is recognized in an amount equal to that excess.
	The Company's most recent annual impairment testing, which consisted of both qualitative and quantitative assessments, did not result in any goodwill impairment charges during the fourth quarter of the fiscal year ended June 30, 2014. Further, the results of our quantitative assessment indicated that the estimated fair value of each reporting unit evaluated substantially exceeded its respective carrying amount.
	Intangible Assets and Other Long-Lived Assets
	Intangible assets consist of acquired technology, customer relationships and trade names, and are amortized over their estimated useful lives.
	The Company evaluates long-lived assets, such as intangible assets and property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company assesses the recoverability of its long-lived assets by determining whether the unamortized balances can be recovered through undiscounted future net cash flows of the related assets. An asset is considered impaired if its carrying amount exceeds the future net cash flow the asset is expected to generate.
	The amount of impairment, if any, is measured based on the fair value of the assets as compared to their carrying value. During the fiscal years ended June 30, 2014, 2013 and 2012, the Company did not record any impairment on long-lived assets.
	Income Taxes
	The Company accounts for income taxes under the asset and liability approach. Deferred tax assets or liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities as measured by the enacted tax rates which will be in effect when these differences reverse. The Company provides a valuation allowance against net deferred tax assets when based upon the available evidence, it is more likely than not that the deferred tax assets will not be realized.
	The Company prepares and files tax returns based on interpretations of tax laws and regulations. The Company's tax returns are subject to examination by various taxing authorities in the normal course of business. Such examinations may result in future tax and interest assessments by these taxing authorities.
	In determining the Company's tax expense for financial reporting purposes, the Company establishes a reserve for uncertain income tax positions unless it is determined to be "more likely than not" that such tax positions would be sustained upon examination, based on their technical merits. That is, for financial reporting purposes, the Company only recognizes tax benefits taken on the tax return if it believes it is "more likely than not" that such tax positions would be sustained. There is considerable judgment involved in determining whether it is "more likely than not" that positions taken on the tax returns would be sustained.
	The Company adjusts its tax reserve estimates periodically because of ongoing examinations by, and settlements with, varying taxing authorities, as well as changes in tax laws, regulations and interpretations. The consolidated tax expense of any given year includes adjustments to prior year income tax accruals and related estimated interest charges that are considered appropriate. The Company's policy is to recognize, when applicable, interest and penalties on uncertain income tax positions as part of income tax expense.
	Redeemable Limited Partner's Capital
	The LP agreement includes a provision that provides for redemption of a limited partner’s interest upon termination as follows:   For Class B common units not yet eligible for exchange, those will be redeemed at a purchase price which is the lower of the limited partner’s capital account balance in Premier LP immediately prior to the IPO after considering any IPO procceds received and the fair market value of the Class A common stock of the Company on the date of the termination with either (a) a five-year, unsecured, non-interest bearing term promissory note, (b) a cashier’s check or wire transfer of immediately available funds in an amount equal to the present value of the Class B unit redemption amount, or (c) payment on such other terms mutually agreed upon with Premier GP.   For Class B common units that are eligible for exchange, the limited partner is also required to exchange all eligible Class B common units on the next exchange date following the date of the termination.
	A limited partner cannot redeem all or any part of its interest in Premier LP without the approval of Premier GP, which is controlled by the board of directors. Given the limited partners hold the majority of the votes of the board of directors, limited partners' capital has a redemption feature that is not solely within the control of the Company. As a result, the Company reflects limited partners’ capital on the consolidated balance sheets as redeemable limited partners’ capital in temporary equity.  In addition, the limited partners have the ability to exchange their Class B common units for cash or Class A common shares on a one-for-one basis. Accordingly, the Company records redeemable limited partners' capital at the greater of the book value or redemption amount per the LP Agreement at the reporting date, with the corresponding offset to additional paid-in-capital and retained earnings (accumulated deficit).
	Tax Receivable Agreements
	The Company records a liability related to the tax receivable agreements based on 85% of the estimated amount of tax savings the Company expects to receive, generally over a 15-year period, in connection with the additional tax benefits created in connection with the Reorganization and IPO. Tax payments under the tax receivable agreements will be made to our member owners as we realize tax benefits attributable to the initial purchase of Class B common units from the member owners in the Reorganization and IPO and any subsequent exchanges of Class B common units into Class A common stock or cash between us and the member owners. Determining the estimated amount of tax savings we expect to receive requires judgment as deductibility of goodwill amortization expense is not assured and the estimate of tax savings is dependent upon the actual realization of the tax benefit and the tax rates in effect at that time.
	Changes in the estimated tax receivable agreement liability are recorded in selling, general and administrative expense in the consolidated statements of income.
	Revenue Recognition
	Net Revenue
	Net revenue consists of (i) service revenue which includes net administrative fees revenue and other services and support revenue and (ii) product revenue. Net administrative fees revenue consists of net GPO administrative fees in the supply chain segment. Other services and support revenue consists primarily of fees generated by the performance services segment in connection with the Company's SaaS informatics products subscriptions, advisory services and performance improvement collaborative subscriptions. Product revenue consists of specialty pharmacy and direct sourcing product sales, which are included in the supply chain segment. The Company recognizes revenue when (i) there is persuasive evidence of an arrangement, (ii) the fee is fixed or determinable, (iii) services have been rendered and payment has been contractually earned, and (iv) collectability is reasonably assured.
	Net Administrative Fees Revenue
	Net administrative fees revenue is generated through administrative fees received from suppliers based on the total dollar volume of supplies purchased by the Company's members in connection with its GPO programs.
	The Company, through its group purchasing program, aggregates member purchasing power to negotiate pricing discounts and improve contract terms with suppliers. Contracted suppliers pay the Company administrative fees which generally represent 1% to 3% of the purchase price of goods and services sold to members under the contracts the Company has negotiated. Administrative fees are recognized as revenue in the period in which the respective supplier reports member purchasing data, usually a month or a quarter in arrears of actual member purchase activity. The supplier report proves that the delivery of product or service has occurred, the administrative fees are fixed and determinable based on reported purchasing volume, and collectability is reasonably assured. Member and supplier contracts substantiate persuasive evidence of an arrangement. The Company does not take title to the underlying equipment or products purchased by members through its GPO supplier contracts.
	The Company pays a revenue share equal to a percentage of gross administrative fees that the Company collects based upon purchasing by such members and their owned, leased, managed or affiliated facilities through its GPO supplier contracts. Revenue share is recognized according to the members' contractual agreements with the Company as the related administrative fees revenue is recognized. Considering GAAP relating to principal/agent considerations under revenue recognition, revenue share is recorded as a reduction to gross administrative fees revenue to arrive at a net administrative fees revenue amount, which amount is included in service revenue in the accompanying consolidated statements of income.
	Other Services and Support Revenue
	Performance services revenue consists of SaaS informatics products subscriptions, performance improvement collaborative and other service subscriptions, professional fees for advisory services, and insurance services management fees and commissions from group-sponsored insurance programs.
	SaaS informatics subscriptions include the right to use the Company's proprietary hosted technology on a SaaS basis, training and member support to deliver improvements in cost management, quality and safety, population health management and provider analytics. Pricing varies by application and size of healthcare system. Informatics subscriptions are generally three to five year agreements with automatic renewal clauses and annual price escalators that typically do not allow for early termination. These agreements do not allow for physical possession of the software. Subscription fees are typically billed on a monthly basis and revenue is recognized as a single deliverable on a straight-line basis over the remaining contractual period following implementation. Implementation involves the completion of data preparation services that are unique to each member's data set and, in certain cases, the installation of member site-specific software, in order to access and transfer member data into the Company's hosted SaaS informatics products. Implementation is generally 110 to 160 days following contract execution before the SaaS informatics products can be fully utilized by the member.
	Revenue from performance improvement collaboratives and other service subscriptions that support the Company's offerings in cost management, quality and safety and population health management is recognized over the service period, which is generally one year.
	Professional fees for advisory services are sold under contracts, the terms of which vary based on the nature of the engagement. Fees are billed as stipulated in the contract, and revenue is recognized on a proportional performance method as services are performed and deliverables are provided. In situations where the contracts have significant contract performance guarantees or member acceptance provisions, revenue recognition occurs when the fees are fixed and determinable and all contingencies, including any refund rights, have been satisfied.
	Insurance services management fees are recognized in the period in which such services are provided. Commissions from group sponsored insurance programs are recognized over the term of the insurance policies, generally one year.
	Certain administrative and/or patient management specialty pharmacy services are provided in situations where prescriptions are sent back to member health systems for dispensing. Additionally, the Company derives revenue from pharmaceutical manufacturers for providing patient education and utilization data. Revenue is recognized as these services are provided.
Product Revenue
Specialty pharmacy revenue is recognized when a product is accepted and is recorded net of the estimated contractual adjustments under agreements with Medicare, Medicaid and other managed care plans. Payments for the products provided under such agreements are based on defined allowable reimbursements rather than on the basis of standard billing rates. The difference between the standard billing rate and allowable reimbursement rate results in contractual adjustments which are recorded as deductions from net revenue.
Direct sourcing revenue is recognized once the title and risk of loss of medical products have been transferred to members.
Multiple Deliverable Arrangements
The Company occasionally enters into agreements where the individual deliverables discussed above, such as SaaS subscriptions and advisory services, are bundled into a single service arrangement. These agreements are generally provided over a time period ranging from approximately three months to five years after the applicable contract execution date. Revenue is allocated to the individual elements within the arrangement based on their relative selling price using vendor specific objective evidence ("VSOE"), third-party evidence ("TPE") or the estimated selling price ("ESP"), provided that the total arrangement consideration is fixed and determinable at the inception of the arrangement. The Company establishes VSOE, TPE, or ESP for each element of a service arrangement based on the price charged for a particular element when it is sold separately in a stand-alone arrangement. All deliverables which are fixed and determinable are recognized according to the revenue recognition methodology described above.
Certain arrangements include performance targets or other contingent fees that are not fixed and determinable at the inception of the arrangement. If the total arrangement consideration is not fixed and determinable at the inception of the arrangement, the Company allocates only that portion of the arrangement that is fixed and determinable to each element. As additional consideration becomes fixed, it is similarly allocated based on VSOE, TPE or ESP to each element in the arrangement and recognized in accordance with each element's revenue recognition policy.
Performance Guarantees
On limited occasions, the Company may enter into an agreement which provides for guaranteed performance levels to be achieved by the member over the term of the agreement. In situations with significant performance guarantees, the Company defers revenue recognition until the amount is fixed and determinable and all contingencies, including any refund rights, have been satisfied. In the event that guaranteed savings levels are not achieved, the Company may have to pay the difference between the savings that were guaranteed and the actual achieved savings.
Deferred Revenue
Deferred revenue consists of unrecognized revenue related to advanced member invoicing or member payments received prior to fulfillment of the Company's revenue recognition criteria. Substantially all deferred revenue consists of deferred subscription fees and deferred advisory fees. Subscription fees for company-hosted SaaS applications are deferred until the member's unique data records have been incorporated into the underlying software database, or until member site-specific software has been implemented and the member has access to the software. Deferred advisory fees arise when cash is received from members prior to delivery of service. When the fees are contingent upon meeting a performance target that has not yet been achieved, the advisory fees are deferred until the performance target is met.
Cost of Revenue and Operating Expenses
Cost of Revenue
Cost of service revenue includes expenses related to employees (including compensation and benefits) and outside consultants who directly provide services related to revenue-generating activities, including advisory services to members and implementation services related to SaaS informatics products. Cost of service revenue also includes expenses related to hosting services, related data center capacity costs, third-party product license expenses and amortization of the cost of internal use software.
Cost of product revenue consists of purchase and shipment costs for specialty pharmaceuticals and direct sourced medical products.
Operating Expenses
Selling, general and administrative expenses consist of expenses directly associated with selling and administrative employees and indirect expenses associated with employees that primarily support revenue generating activities (including compensation and benefits) and travel-related expenses, as well as occupancy and other indirect expenses, insurance expenses, professional fees, and other general overhead expenses.
Research and development expenses consist of employee-related compensation and benefits expenses, and third-party consulting fees of technology professionals, incurred to develop, support and maintain the Company's software-related products and services.
Amortization of purchased intangible assets includes the amortization of all identified intangible assets resulting from acquisitions.
Advertising Costs
Advertising costs are expensed as incurred. Advertising costs are reflected in selling, general and administrative expenses in the accompanying consolidated statements of income and were $1.7 million, $1.4 million and $1.5 million for the years ended June 30, 2014, 2013 and 2012, respectively.
Comprehensive Income
Comprehensive income includes all changes in stockholders' equity during a period from non-owner sources. Net income and other comprehensive income, including unrealized gains and losses on investments, are reported, net of their related tax effect, to arrive at comprehensive income.
Basic and Diluted Earnings per Share
Basic earnings per share ("EPS") is calculated by dividing net income by the number of weighted average common shares outstanding during the period. Diluted EPS assumes the conversion, exercise or issuance of all potential common stock equivalents, unless the effect of inclusion would result in the reduction of a loss or the increase in income per share. Diluted EPS is computed by dividing net income by the number of weighted average common shares increased by the dilutive effects of potential common shares outstanding during the period. The number of potential common shares outstanding is determined in accordance with the treasury stock method. Common stock subscribed is included in the calculation of basic EPS, since the subscribed shares have full voting and dividend participation rights on the day of subscription.
Recently Adopted Accounting Standards
In February 2013, the FASB issued an ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires presentation of information about significant amounts reclassified from each component of accumulated other comprehensive income, the sources of the items reclassified, and the income statement lines affected, either parenthetically on the face of the financial statements or in the notes to the financial statements. The adoption of this accounting standard during the year ended June 30, 2014 had no significant impact on the Company's consolidated financial statements or related disclosures.
Recently Issued Accounting Standards
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of the update is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The update 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 update will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is not permitted. The update allows for either full retrospective or modified retrospective adoption. The Company is currently evaluating the transition method that will be elected as well as the impact of the adoption of the update on its consolidated financial statements and related disclosures.

BUSINESS ACQUISITIONS	'
	BUSINESS ACQUISITIONS
	On April 7, 2014, Premier completed the acquisition of MEMdata, LLC ("MEMdata"), an equipment planning, sourcing and analytics business focused on capital equipment needs for existing medical facilities, as well as those under construction, for $6.2 million. The Company funded the acquisition with available cash on hand. The primary reason for the acquisition of MEMdata was to enhance Premier's ability to drive meaningful supply chain savings for its hospital and health system members in the high-cost areas of construction and capital equipment acquisitions.
	The purchase price exceeded the fair value of the net tangible and identifiable intangible assets acquired from MEMdata. As a result, the Company recorded goodwill in connection with this acquisition, which was assigned to the performance services segment. The Company filed an Internal Revenue Code Section 338(h)(10) election for the acquisition, has treated the purchase as an asset acquisition for income tax purposes, and is deducting the recognized goodwill for income tax purposes.
	The allocation of the preliminary purchase price to the assets acquired and liabilities assumed based on their fair values, is as follows (in thousands):
	Net tangible assets acquired	$	164
	Intangible assets acquired	1,890
	Goodwill	4,152
	Total	$	6,206
	The $1.9 million value allocated to intangible assets consists of $1.4 million of acquired technology with useful lives ranging from 4 to 7 years, member relationships of $0.3 million with a useful life of 8 years, and non-compete agreements and trade names of $0.2 million with useful lives ranging from 2 to 3 years.
	On October 31, 2013, Premier completed the acquisition of Meddius, L.L.C. ("Meddius"), a data acquisition and integration-as-a-service company that spans multiple hospital transaction systems including enterprise resource planning, materials management, enterprise health records and patient accounting, for $8.1 million. The Company funded the acquisition with available cash on hand. The primary reason for the acquisition of Meddius was to augment the Company's capabilities for automated data acquisition across the PremierConnect™ platform and associated applications.

	On June 24, 2014, Premier LP, along with its wholly owned subsidiaries, Premier Supply Chain Improvement, Inc. (“PSCI”) and PHSI, as Co-Borrowers, Premier GP, and certain domestic subsidiaries of Premier GP, as Guarantors, Wells Fargo Bank, National Association, as Administrative Agent (the “Administrative Agent”), Swing Line Lender and L/C Issuer, other lenders from time to time party thereto, and Wells Fargo Securities, LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as Joint Lead Arrangers and Joint Book Managers, entered into an unsecured Credit Agreement, dated as of June 24, 2014 (the “Credit Agreement”). The Credit Agreement has a maturity date of June 24, 2019.
	The new credit facility provides for borrowings of up to $750.0 million with (i) a $25.0 million subfacility for standby letters of credit and (ii) a $75.0 million subfacility for swingline loans. At our request, the credit facility may be increased from time to time up to an additional aggregate of $250.0 million, subject to the approval of the lenders providing such increase. 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 is not a guarantor under the credit facility.
	The new credit facility replaced our prior $100 million credit facility, which was terminated on the closing date of the new credit facility. The prior credit facility was scheduled to mature on December 16, 2014. At the time of its termination, there were no outstanding borrowings under the prior credit facility.
	The new credit facility permits us to prepay amounts outstanding without premium or penalty provided, however, we are required to compensate the lenders for losses and expenses incurred as a result of the prepayment of any Eurodollar Rate Loan, as defined in the credit facility. Committed loans may be in the form of Eurodollar Rate Loans or Base Rate Loans, as defined in the credit facility, at our option. Eurodollar Rate Loans bear interest at the Eurodollar Rate (defined as the London Interbank Offer 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 Rate Loans and 0.125% to 0.750% for Base Rate Loans. At June 30, 2014, the interest rate for three-month Eurodollar Rate Loans was 1.356% and the interest rate for Base Rate Loans was 3.375%. We are required to pay a commitment fee ranging from 0.125% to 0.250% per annum on the actual daily unused amount of commitments under the credit facility. At June 30, 2014, the commitment fee was 0.125%.
	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 fiscal quarters. In addition, Premier GP must maintain a minimum Consolidated Interest Coverage Ratio (as defined in the credit facility) of 3.00 to 1.00 at the end of every fiscal quarter. We were compliance with all such covenants at June 30, 2014. The credit facility also contains customary events of default including, among others, payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults of any indebtedness or guarantees in excess of $30.0 million, bankruptcy and other insolvency events, judgment defaults in excess of $30.0 million, and the occurrence of a change of control (as defined in the credit facility). If any event of default occurs and is continuing, the Administrative Agent under the credit facility may, with the consent, or shall, at the request, of the required lenders, terminate the commitments and declare all of the amounts owed under the credit facility to be immediately due and payable.
	Proceeds from borrowings under the credit facility may generally be used to finance ongoing working capital requirements, including permitted acquisitions and other general corporate purposes. As of the June 30, 2014, we had no outstanding borrowings under our new credit facility.
	On August 17, 2012, S2S Global, a direct sourcing business which the Company consolidates and owns 60% of the outstanding shares of common stock, obtained a revolving line of credit with a one‑year term for up to $10.0 million at an interest rate which is generally the lower of LIBOR plus 1.25% or the Prime Rate plus 0.25%. On August 2, 2013, S2S Global renewed and amended its revolving line of credit to include a $15.0 million credit limit and a $5.0 million accordion feature. On January 30, 2014, S2S Global further amended its revolving line of credit to increase the credit limit to $20.0 million. The S2S Global revolving line of credit has customary covenants, which include, but are not limited to those regarding: the use of proceeds, provision of financial information, restriction on other debts and liens, maintenance of assets, investments, taxes, nature of business, mergers, transactions with affiliates, restricted payments, insurance and compliance with laws. S2S Global was in compliance with all such covenants at June 30, 2014. The amended revolving line of credit has a maturity date of December 16, 2014. The unused commitment fee on the revolving line of credit is 0.225% per annum.
	At June 30, 2014 and June 30, 2013, S2S Global had $13.7 million and $7.7 million, respectively, outstanding on the revolving line of credit, which is included in current portion of notes payable and line of credit in the accompanying consolidated balance sheets.

	The Company delivers its solutions and manages its business through two reportable business segments, the supply chain services segment and the performance services segment. The supply chain services segment includes the Company's GPO, a specialty pharmacy and direct sourcing activities. The performance services segment includes the Company's informatics, collaborative, advisory services and insurance services businesses.
	The Company uses Segment Adjusted EBITDA (as defined herein) as its primary measure of profit or loss to assess segment performance and to determine the allocation of resources. The Company also uses Segment Adjusted EBITDA to facilitate the comparison of the segment operating performance on a consistent basis from period to period. The Company defines Segment Adjusted EBITDA as the segment's net revenue less operating expenses directly attributable to the segment excluding depreciation and amortization, amortization of purchased intangible assets, merger and acquisition related expenses and non-recurring or non-cash items, and including equity in net income of unconsolidated affiliates. 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 clients.

REDEEMABLE LIMITED PARTNERS' CAPITAL	12 Months Ended

Temporary Equity Disclosure [Abstract]	'
REDEEMABLE LIMITED PARTNERS' CAPITAL	'
	REDEEMABLE LIMITED PARTNERS' CAPITAL
	At June 30, 2013, redeemable limited partners' capital represents the limited partners' 99% ownership of Premier LP. Pursuant to the terms of the historical limited partnership agreement, 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 the existing limited partnership agreement of Premier LP. As a result, at June 30, 2013, the redeemable limited partners' capital is classified as temporary equity in the mezzanine section of the 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' 78% ownership of Premier LP at June 30, 2014. 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 still required and the redeemable limited partners' capital, which is recorded at the greater of the book value or redemption amount per the LP Agreement, is classified as temporary equity in the mezzanine section of the consolidated balance sheet at June 30, 2014. 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.
	The table below shows the changes in the redeemable limited partners' capital classified as temporary equity from June 30, 2011 to June 30, 2014 (in thousands):

	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 so that 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 year ended June 30, 2014.
	During the year ended June 30, 2014, one limited partner 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 former limited partners are reflected in notes payable in the accompanying consolidated balance sheets.
	Prior to the consummation of the Reorganization and IPO, Premier LP maintained a discretionary distribution policy in which semi-annual cash distributions were made each February attributable to the recently completed six months ended December 31 and each September attributable to the recently completed six months ended June 30. As provided in the then existing limited partnership agreement, the amount of actual cash distributed may have been reduced by the amount of such distributions used by limited partners to offset contribution loans or other amounts payable to the Company.
	Premier LP distributed $214.5 million to its limited partners during the three months ended September 30, 2013 attributable to income generated through June 30, 2013, of which $2.8 million was retained to reduce limited partner notes payable and related interest obligations and an additional $3.4 million was retained to reduce other amounts payable by limited partners to the Company, resulting in a cash distribution of $208.3 million. During the three months ended December 31, 2013, Premier LP distributed cash of $72.6 million to its limited partners attributable to income generated through September 30, 2013.
	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 instead of a semi-annual basis due within 60 days of each calendar quarter-end. As provided in the limited partnership 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 May 29, 2014 to its limited partners of $21.4 million and a quarterly distribution on February 27, 2014 to its limited partners of $17.4 million. Each distribution was equal to the previous fiscal quarter's total taxable income for Premier LP multiplied by the effective combined federal, state and local income tax rate.
	Premier LP made a quarterly distribution on August 28, 2014 to its limited partners of $22.4 million, which is reflected as a liability as of June 30, 2014 in the accompanying consolidated balance sheets. Consistent with the Company's discretionary distribution policy prior to the Reorganization and IPO, the Company had no such distribution payable at June 30, 2013.

	Stock-based compensation expense is recognized over the requisite service period, which generally equals the stated vesting period. Pre-tax stock-based compensation expense was $19.5 million for the year ended June 30, 2014, with a resulting deferred tax benefit of $7.4 million, respectively, calculated at a rate of 38%. At June 30, 2014, there was $45.9 million of unrecognized stock-based compensation expense related to non-vested awards that will be amortized over 2.01 years. There was no stock compensation expense for the year ended June 30, 2013.
	Premier 2013 Equity Incentive Plan
	The Premier 2013 Equity Incentive Plan (the "2013 Equity Incentive Plan") provides for grants of up to 11,260,783 shares of Class A common stock, all of which are eligible to be issued as non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units or performance awards. As of June 30, 2014, there were 7,667,266 shares available for grant under the 2013 Equity Incentive Plan.
	Restricted Stock Units. On September 25, 2013, Premier granted 414,987 restricted stock units to certain executive level employees, 11,112 restricted stock units to non-employee directors and 282,800 restricted stock units to all non-executive level employees, with a grant date fair value of $27.00 per share. The employee restricted stock units vest in full on June 30, 2016 and the non-employee board of director restricted stock units vest in full on September 25, 2014.
	During the year ended June 30, 2014, an additional 31,895 restricted stock units were granted to certain employees and 6,464 restricted stock units were granted to new non-employee directors, with an average grant date fair value of $32.59.
	During the year ended June 30, 2014, 1,042 restricted stock units vested on a pro-rata basis related to qualifying terminations and 27,996 restricted stock units were forfeited.
	Performance Share Awards. On September 25, 2013, Premier granted 829,922 performance share awards, with a grant date fair value of $27.00 per share, to certain employees. The performance share awards vest on June 30, 2016, either in part or in full, contingent upon the achievement of certain performance criteria.
	During the year ended June 30, 2014, 2,748 performance share awards were forfeited.
	Stock Options. Stock options have a term of 10 years from the date of grant; however, 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. On September 25, 2013, Premier granted 2,054,192 stock options, with an exercise price equal to the fair market value of a share of Premier's common stock on the grant date of $27.00 per share, to certain employees. The stock options vest in three equal annual installments, beginning on June 30, 2014.
	During the year ended June 30, 2014, 6,708 stock options were forfeited.
	For purposes of determining compensation expense, the grant date fair value per share of the stock options was estimated using the Black-Scholes option pricing model which requires the use of various assumptions including the expected life of the option, expected dividend rate, expected volatility and risk-free interest rate. Key assumptions used for determining the fair value of stock options granted were as follows:
	Expected life (1)	6 years
	Expected dividend (2)	—
	Expected volatility (3)	42		%
	Risk-free interest rate (4)	1.71		%
	Weighted average option grant date fair value	$	11.46
	(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 constant maturity market yield as of the date of the grant.
	On August 29, 2014, Premier granted 140,054 restricted stock units and 269,840 performance share awards to certain executive and non-executive level employees, with a grant date fair value of $31.58 per share. On August 29, 2014, Premier granted 636,342 stock options to certain executive and non-executive level employees, with an exercise price of $31.58 per share, which equals the fair market value of a share of Premier's common stock on the grant date.

	INCOME TAXES
	The Company's income tax expense is attributable to the activities of the Company, PHSI and PSCI, which are all 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.

	Effective income tax rate	7.7		%	2.5		%	2.5		%
	The effective tax rate has increased from the prior year as a result of the Reorganization which created additional partnership income subject to tax at the Company level.
	Federal tax years ended June 30, 2013, 2012, and 2011 have not been examined by the Internal Revenue Service ("IRS") and remain open as of June 30, 2014. The Company believes it has recorded adequate taxes for positions taken which may be challenged upon IRS examination.
	The Company has federal net operating loss carryforwards that will be available to offset federal taxable income of PHSI and its consolidated subsidiaries. These loss carryforwards are subject to an annual limitation of approximately $1.4 million under the provisions of IRC Section 382. At June 30, 2014, the Company had federal net operating loss carryforwards of $9.3 million that will begin expiring on June 30, 2017 unless utilized. At June 30, 2014, the Company had state net operating loss carryforwards of $5.5 million that will begin expiring on June 30, 2015, and PSCI had state net operating loss carryforwards of $8.9 million that will begin expiring on June 30, 2016, unless utilized, based on each respective state's regulations regarding carryforward limitations.
	Deferred income taxes reflect the net effects of temporary differences between the carrying amounts of assets and the liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company annually assesses whether a valuation allowance is necessary against net deferred tax assets. Based on the Company's assessment, we have concluded that it is more likely than not that all of the deferred tax assets will be realized, except for certain state net operating losses as of June 30, 2014 that are expected to expire. Accordingly, as of June 30, 2014 and 2013, the Company has recognized net deferred tax assets of $296.6 million and $23.5 million, respectively. The significant increase in deferred tax assets is the result of intangible assets acquired in connection with the Reorganization and IPO.

	On October 1, 2013, the Company recorded deferred tax assets of $283.0 million associated with basis differences in assets upon acquiring an interest in Premier LP and making a Section 754 election in connection with the Reorganization and IPO. The Company also recorded $186.1 million in tax receivable agreement liabilities representing 85% of the tax savings that the Company expects to receive in connection with the Section 754 election. In June 2014, Premier LP received approval for a tax accounting method change that resulted in deferred tax assets increasing by $2.4 million to $285.4 million. The Company also recorded an additional $6.2 million in tax receivable agreement liabilities to the existing $186.1 million which results in $192.3 million in tax receivable agreement liabilities as of June 30, 2014. Both resulted from additional basis differences due to the accounting method change. The original recording of deferred tax assets was offset by the tax receivable liabilities with the resulting difference recorded to paid-in-capital. The adjustment to deferred tax assets and liabilities resulted in a $2.4 million reduction to tax expense that is not anticipated to occur in the future.
	A reconciliation of the beginning and ending gross amounts of the Company's uncertain tax position reserves for the fiscal years ended June 30, 2014 and June 30, 2013 are as follows:
		June 30,

	Increases in current period tax positions	579			281			28
	End of year balance	1,438			759			478
The total reserve for uncertain tax positions that affect the Company’s effective tax rate is approximately $1.4 million, $0.8 million, and $0.5 million as of June 30, 2014, 2013 and 2012, respectively. It is expected that the reserves will change in the next twelve months; however, the Company does not expect the changes in its reserve to have a material impact on its financial statements.

EARNINGS PER SHARE	'
	EARNINGS (LOSS) PER SHARE
	Basic earnings per share of Premier is computed by dividing net (loss) income attributable to shareholders after adjustment of redeemable limited partners' capital to redemption amount by the weighted average number of shares of common stock outstanding for the period. Net (loss) income attributable to shareholders after adjustment of redeemable limited partners' capital to redemption amount reflects the adjustment recorded in the period to reflect redeemable limited partners' capital at the redemption amount, as a result of the 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, shares of non-vested performance share awards and shares that could be issued under the outstanding stock options.

SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended

Accounting Policies [Abstract]	'
Basis of Presentation and Consolidation	'
	The Company, through its wholly owned subsidiary, Premier Services, LLC ("Premier GP"), holds a 22% controlling general partner interest in and, as a result, consolidates the financial statements of Premier Healthcare Alliance, L.P. ("Premier LP"). The limited partners' 78% ownership of Premier LP is reflected as redeemable limited partners' capital in the Company's consolidated balance sheets, and their proportionate share of income in Premier LP is reflected within net income attributable to noncontrolling interest in Premier LP in the Company's consolidated statements of income and within comprehensive income attributable to noncontrolling interest in the consolidated statements of comprehensive income.
	After the completion of a series of transactions following the consummation of the initial public offering ("IPO"), referred to as the "Reorganization," Premier Healthcare Solutions, Inc. ("PHSI") became a consolidated subsidiary of the Company. PHSI is considered the predecessor of the Company for accounting purposes, and accordingly, PHSI's consolidated financial statements are the Company's historical financial statements, for periods prior to October 1, 2013. The historical consolidated financial statements of PHSI are reflected herein based on PHSI's historical ownership interests of Premier LP and its consolidated subsidiaries. Refer to Note 2 for further information related to the IPO and the Reorganization.
	The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Accordingly, the 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 periods shown, including normal recurring adjustments.
	The Company has reclassified certain prior period amounts to be consistent with the current period presentation in the accompanying consolidated financial statements and corrected certain classification differences in the consolidated statements of cash flows. For the year ended June 30, 2013, the Company has presented $3 million in costs associated with the IPO as financing rather than operating activities.
Use of Estimates in the Preparation of Financial Statements	'
	The preparation of the Company's consolidated financial statements 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. Estimates are evaluated on an ongoing basis, including 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 and the fair value of purchased intangible assets and goodwill. 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.
Cash and Cash Equivalents	'
	Cash and cash equivalents include cash and highly liquid investments with remaining maturities of three months or less at the time of acquisition.
Concentration of Credit Risk	'
	Financial instruments that subject the Company to potential concentrations of credit risk consist primarily of the Company's receivables and marketable securities. Receivables consist primarily of amounts due from hospital and healthcare system members for services and products.
Allowance for Doubtful Accounts	'
	The Company maintains an allowance for doubtful accounts. This allowance is an estimate and is regularly evaluated by the Company for adequacy by taking into consideration factors such as past experience, credit quality of the member base, age of the receivable balances, both individually and in the aggregate, and current economic conditions that may affect a member's ability to pay. Provisions for the allowance for doubtful accounts attributed to bad debt are recorded in selling, general and administrative expenses in the accompanying consolidated statements of income.
Fair Value of Financial Instruments	'
	The fair value of an asset or liability is based on the assumptions that market participants would use in pricing the asset or liability. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value. The Company follows a three-tiered fair value hierarchy when determining the inputs to valuation techniques. The fair value hierarchy prioritizes the inputs to valuation techniques into three broad levels in order to maximize the use of observable inputs and minimize the use of unobservable inputs. The levels of the fair value hierarchy are as follows:
	Level 1: consists of financial instruments whose values are based on quoted market prices for identical financial instruments in an active market;
	Level 2: consists of financial instruments whose values are determined using models or other valuation methodologies that utilize inputs that are observable either directly or indirectly, including (i) quoted prices for similar assets or liabilities in active markets, (ii) quoted prices for identical or similar assets or liabilities in markets that are not active, (iii) pricing models whose inputs are observable for substantially the full term of the financial instrument and (iv) pricing models whose inputs are derived principally from or corroborated by observable market data through correlation or other means for substantially the full term of the financial instrument;
	Level 3: consists of financial instruments whose values are determined using pricing models that utilize significant inputs that are primarily unobservable, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
Marketable Securities	'
	The Company invests its excess cash in commercial paper, corporate debt securities, government securities and other securities with maturities generally ranging from three months to five years from the date of purchase. Marketable securities, classified as available-for-sale, are carried at fair market value, with the unrealized gains and losses on such investments reported in comprehensive income as a separate component of stockholders' (deficit) equity or redeemable limited partners' capital as appropriate. Realized gains and losses, and other-than-temporary declines in investments, are included in other income, net in the accompanying consolidated statements of income. The Company uses the specific-identification method to determine the cost of securities sold. The Company does not hold publicly traded equity investments.
Inventories	'
	Inventories consisting of medical products and other non-pharmaceutical products are stated at the lower of cost or market on an average cost basis. Inventories consisting of pharmaceuticals and pharmaceutical-related products are stated at the lower of cost or market on a first-in, first-out basis. Management determines the inventory reserve by regularly reviewing and evaluating individual inventory items. Inventory is written off when deemed obsolete or unsellable by management.
Investments	'
	The Company uses the cost method to account for investments in businesses that are not publicly traded and for which the Company does not control or have the ability to exercise significant influence over operating and financial policies. In accordance with the cost method, these investments are recorded at the lower of cost or fair value, as appropriate.
	Investments held by the Company in businesses that are not publicly traded and for which the Company has the ability to exercise significant influence over operating and financial management are accounted for under the equity method. In accordance with the equity method, these investments are originally recorded at cost and are adjusted for the Company's proportionate share of earnings, losses and distributions.
	The Company assesses and records impairment losses when events and circumstances indicate the investments might be impaired. Gains and losses are recognized when realized.
Property and Equipment, Net	'
	Property and equipment is stated at cost. Depreciation is calculated based upon estimated useful lives ranging from three to five years, using the straight-line method. Leasehold improvements are depreciated over the shorter of the estimated useful life of the asset or the lease term.
Software Development Costs	'
	Costs to develop internal use computer software during the application development stage are capitalized. Internal use capitalized software costs are included in property and equipment, net in the accompanying consolidated balance sheets. Capitalized costs are amortized on a straight-line basis over the estimated useful lives of the related software applications of up to five years and amortization is included in cost of revenue in the accompanying consolidated statements of income.
Deferred Compensation Plan Assets and Related Liabilities	'
	The Company maintains a non-qualified deferred compensation plan for the benefit of eligible employees. This plan is designed to permit employee deferrals in excess of certain tax limits and provides for discretionary employer contributions in excess of the tax limits applicable to the Company's 401(k) plan.
	Company assets designated to pay benefits under the plan are held by a rabbi trust and are subject to the general creditors of the Company. The amounts deferred are invested in assets at the direction of the employee.
	The assets, classified as trading securities, and liabilities of the rabbi trust are recorded at fair value and are accounted for as assets and liabilities of the Company. The assets of the rabbi trust are used to fund the deferred compensation liabilities owed to current and former employees. The deferred compensation plan contains both current and non-current assets.
Goodwill	'
	Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill is not amortized. The Company performs its annual goodwill impairment testing on the first day of the last fiscal quarter of its fiscal year unless impairment indicators are present which could require an interim impairment test.
	Under the accounting rules, the Company can elect to perform a qualitative assessment to determine if an impairment is more likely than not to have occurred. This qualitative assessment requires an evaluation of any excess of fair value over the carrying value for a reporting unit and significant judgment regarding potential changes in valuation inputs, including a review of the Company's most recent long-range projections, analysis of operating results versus the prior year, changes in market values, changes in discount rates and changes in terminal growth rate assumptions. If it is determined that an impairment is more likely than not to exist, then we are required to perform a quantitative assessment to determine whether or not goodwill is impaired and to measure the amount of goodwill impairment, if any.
	Goodwill impairment is determined using a two-step process. The first step involves a comparison of the estimated fair value of each of our reporting units to its carrying amount, including goodwill. In performing the first step, we determine the fair value of a reporting unit using a discounted cash flow analysis that is corroborated by a market-based approach. Determining fair value requires the exercise of significant judgment, including judgment about appropriate discount rates, perpetual growth rates and the amount and timing of expected future cash flows. The cash flows employed in the discounted cash flow analyses are based on our most recent budget and long-term forecast. The discount rates used in the discounted cash flow analyses are intended to reflect the risks inherent in the future cash flows of the respective reporting units. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired and the second step of the impairment test is not necessary.
	If the carrying amount of a reporting unit exceeds its estimated fair value, then the second step of the goodwill impairment test must be performed. The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with its goodwill carrying amount to measure the amount of impairment, if any. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. In other words, the estimated fair value of the reporting unit is allocated to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit was the purchase price paid. If the carrying amount of the reporting unit's goodwill exceeds the implied fair value of that goodwill, an impairment charge is recognized in an amount equal to that excess.
Intangible Assets and Other Long-Lived Assets	'
	Intangible assets consist of acquired technology, customer relationships and trade names, and are amortized over their estimated useful lives.
	The Company evaluates long-lived assets, such as intangible assets and property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company assesses the recoverability of its long-lived assets by determining whether the unamortized balances can be recovered through undiscounted future net cash flows of the related assets. An asset is considered impaired if its carrying amount exceeds the future net cash flow the asset is expected to generate.
	The amount of impairment, if any, is measured based on the fair value of the assets as compared to their carrying value
Income Taxes	'
	The Company accounts for income taxes under the asset and liability approach. Deferred tax assets or liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities as measured by the enacted tax rates which will be in effect when these differences reverse. The Company provides a valuation allowance against net deferred tax assets when based upon the available evidence, it is more likely than not that the deferred tax assets will not be realized.
	The Company prepares and files tax returns based on interpretations of tax laws and regulations. The Company's tax returns are subject to examination by various taxing authorities in the normal course of business. Such examinations may result in future tax and interest assessments by these taxing authorities.
	In determining the Company's tax expense for financial reporting purposes, the Company establishes a reserve for uncertain income tax positions unless it is determined to be "more likely than not" that such tax positions would be sustained upon examination, based on their technical merits. That is, for financial reporting purposes, the Company only recognizes tax benefits taken on the tax return if it believes it is "more likely than not" that such tax positions would be sustained. There is considerable judgment involved in determining whether it is "more likely than not" that positions taken on the tax returns would be sustained.
	The Company adjusts its tax reserve estimates periodically because of ongoing examinations by, and settlements with, varying taxing authorities, as well as changes in tax laws, regulations and interpretations. The consolidated tax expense of any given year includes adjustments to prior year income tax accruals and related estimated interest charges that are considered appropriate. The Company's policy is to recognize, when applicable, interest and penalties on uncertain income tax positions as part of income tax expense.
Redeemable Limited Partner's Capital	'
	The LP agreement includes a provision that provides for redemption of a limited partner’s interest upon termination as follows:   For Class B common units not yet eligible for exchange, those will be redeemed at a purchase price which is the lower of the limited partner’s capital account balance in Premier LP immediately prior to the IPO after considering any IPO procceds received and the fair market value of the Class A common stock of the Company on the date of the termination with either (a) a five-year, unsecured, non-interest bearing term promissory note, (b) a cashier’s check or wire transfer of immediately available funds in an amount equal to the present value of the Class B unit redemption amount, or (c) payment on such other terms mutually agreed upon with Premier GP.   For Class B common units that are eligible for exchange, the limited partner is also required to exchange all eligible Class B common units on the next exchange date following the date of the termination.
	A limited partner cannot redeem all or any part of its interest in Premier LP without the approval of Premier GP, which is controlled by the board of directors. Given the limited partners hold the majority of the votes of the board of directors, limited partners' capital has a redemption feature that is not solely within the control of the Company. As a result, the Company reflects limited partners’ capital on the consolidated balance sheets as redeemable limited partners’ capital in temporary equity.  In addition, the limited partners have the ability to exchange their Class B common units for cash or Class A common shares on a one-for-one basis. Accordingly, the Company records redeemable limited partners' capital at the greater of the book value or redemption amount per the LP Agreement at the reporting date, with the corresponding offset to additional paid-in-capital and retained earnings (accumulated deficit).
Tax Receivable Agreement	'
	The Company records a liability related to the tax receivable agreements based on 85% of the estimated amount of tax savings the Company expects to receive, generally over a 15-year period, in connection with the additional tax benefits created in connection with the Reorganization and IPO. Tax payments under the tax receivable agreements will be made to our member owners as we realize tax benefits attributable to the initial purchase of Class B common units from the member owners in the Reorganization and IPO and any subsequent exchanges of Class B common units into Class A common stock or cash between us and the member owners. Determining the estimated amount of tax savings we expect to receive requires judgment as deductibility of goodwill amortization expense is not assured and the estimate of tax savings is dependent upon the actual realization of the tax benefit and the tax rates in effect at that time.
	Changes in the estimated tax receivable agreement liability are recorded in selling, general and administrative expense in the consolidated statements of income.
Revenue Recognition	'
	Net Revenue
	Net revenue consists of (i) service revenue which includes net administrative fees revenue and other services and support revenue and (ii) product revenue. Net administrative fees revenue consists of net GPO administrative fees in the supply chain segment. Other services and support revenue consists primarily of fees generated by the performance services segment in connection with the Company's SaaS informatics products subscriptions, advisory services and performance improvement collaborative subscriptions. Product revenue consists of specialty pharmacy and direct sourcing product sales, which are included in the supply chain segment. The Company recognizes revenue when (i) there is persuasive evidence of an arrangement, (ii) the fee is fixed or determinable, (iii) services have been rendered and payment has been contractually earned, and (iv) collectability is reasonably assured.
	Net Administrative Fees Revenue
	Net administrative fees revenue is generated through administrative fees received from suppliers based on the total dollar volume of supplies purchased by the Company's members in connection with its GPO programs.
	The Company, through its group purchasing program, aggregates member purchasing power to negotiate pricing discounts and improve contract terms with suppliers. Contracted suppliers pay the Company administrative fees which generally represent 1% to 3% of the purchase price of goods and services sold to members under the contracts the Company has negotiated. Administrative fees are recognized as revenue in the period in which the respective supplier reports member purchasing data, usually a month or a quarter in arrears of actual member purchase activity. The supplier report proves that the delivery of product or service has occurred, the administrative fees are fixed and determinable based on reported purchasing volume, and collectability is reasonably assured. Member and supplier contracts substantiate persuasive evidence of an arrangement. The Company does not take title to the underlying equipment or products purchased by members through its GPO supplier contracts.
	The Company pays a revenue share equal to a percentage of gross administrative fees that the Company collects based upon purchasing by such members and their owned, leased, managed or affiliated facilities through its GPO supplier contracts. Revenue share is recognized according to the members' contractual agreements with the Company as the related administrative fees revenue is recognized. Considering GAAP relating to principal/agent considerations under revenue recognition, revenue share is recorded as a reduction to gross administrative fees revenue to arrive at a net administrative fees revenue amount, which amount is included in service revenue in the accompanying consolidated statements of income.
	Other Services and Support Revenue
	Performance services revenue consists of SaaS informatics products subscriptions, performance improvement collaborative and other service subscriptions, professional fees for advisory services, and insurance services management fees and commissions from group-sponsored insurance programs.
	SaaS informatics subscriptions include the right to use the Company's proprietary hosted technology on a SaaS basis, training and member support to deliver improvements in cost management, quality and safety, population health management and provider analytics. Pricing varies by application and size of healthcare system. Informatics subscriptions are generally three to five year agreements with automatic renewal clauses and annual price escalators that typically do not allow for early termination. These agreements do not allow for physical possession of the software. Subscription fees are typically billed on a monthly basis and revenue is recognized as a single deliverable on a straight-line basis over the remaining contractual period following implementation. Implementation involves the completion of data preparation services that are unique to each member's data set and, in certain cases, the installation of member site-specific software, in order to access and transfer member data into the Company's hosted SaaS informatics products. Implementation is generally 110 to 160 days following contract execution before the SaaS informatics products can be fully utilized by the member.
	Revenue from performance improvement collaboratives and other service subscriptions that support the Company's offerings in cost management, quality and safety and population health management is recognized over the service period, which is generally one year.
	Professional fees for advisory services are sold under contracts, the terms of which vary based on the nature of the engagement. Fees are billed as stipulated in the contract, and revenue is recognized on a proportional performance method as services are performed and deliverables are provided. In situations where the contracts have significant contract performance guarantees or member acceptance provisions, revenue recognition occurs when the fees are fixed and determinable and all contingencies, including any refund rights, have been satisfied.
	Insurance services management fees are recognized in the period in which such services are provided. Commissions from group sponsored insurance programs are recognized over the term of the insurance policies, generally one year.
	Certain administrative and/or patient management specialty pharmacy services are provided in situations where prescriptions are sent back to member health systems for dispensing. Additionally, the Company derives revenue from pharmaceutical manufacturers for providing patient education and utilization data. Revenue is recognized as these services are provided.
	Product Revenue
	Specialty pharmacy revenue is recognized when a product is accepted and is recorded net of the estimated contractual adjustments under agreements with Medicare, Medicaid and other managed care plans. Payments for the products provided under such agreements are based on defined allowable reimbursements rather than on the basis of standard billing rates. The difference between the standard billing rate and allowable reimbursement rate results in contractual adjustments which are recorded as deductions from net revenue.
	Direct sourcing revenue is recognized once the title and risk of loss of medical products have been transferred to members.
	Multiple Deliverable Arrangements
	The Company occasionally enters into agreements where the individual deliverables discussed above, such as SaaS subscriptions and advisory services, are bundled into a single service arrangement. These agreements are generally provided over a time period ranging from approximately three months to five years after the applicable contract execution date. Revenue is allocated to the individual elements within the arrangement based on their relative selling price using vendor specific objective evidence ("VSOE"), third-party evidence ("TPE") or the estimated selling price ("ESP"), provided that the total arrangement consideration is fixed and determinable at the inception of the arrangement. The Company establishes VSOE, TPE, or ESP for each element of a service arrangement based on the price charged for a particular element when it is sold separately in a stand-alone arrangement. All deliverables which are fixed and determinable are recognized according to the revenue recognition methodology described above.
	Certain arrangements include performance targets or other contingent fees that are not fixed and determinable at the inception of the arrangement. If the total arrangement consideration is not fixed and determinable at the inception of the arrangement, the Company allocates only that portion of the arrangement that is fixed and determinable to each element. As additional consideration becomes fixed, it is similarly allocated based on VSOE, TPE or ESP to each element in the arrangement and recognized in accordance with each element's revenue recognition policy.
	Performance Guarantees
	On limited occasions, the Company may enter into an agreement which provides for guaranteed performance levels to be achieved by the member over the term of the agreement. In situations with significant performance guarantees, the Company defers revenue recognition until the amount is fixed and determinable and all contingencies, including any refund rights, have been satisfied. In the event that guaranteed savings levels are not achieved, the Company may have to pay the difference between the savings that were guaranteed and the actual achieved savings.
	Deferred Revenue
	Deferred revenue consists of unrecognized revenue related to advanced member invoicing or member payments received prior to fulfillment of the Company's revenue recognition criteria. Substantially all deferred revenue consists of deferred subscription fees and deferred advisory fees. Subscription fees for company-hosted SaaS applications are deferred until the member's unique data records have been incorporated into the underlying software database, or until member site-specific software has been implemented and the member has access to the software. Deferred advisory fees arise when cash is received from members prior to delivery of service. When the fees are contingent upon meeting a performance target that has not yet been achieved, the advisory fees are deferred until the performance target is met.
Cost of Revenue	'
	Cost of service revenue includes expenses related to employees (including compensation and benefits) and outside consultants who directly provide services related to revenue-generating activities, including advisory services to members and implementation services related to SaaS informatics products. Cost of service revenue also includes expenses related to hosting services, related data center capacity costs, third-party product license expenses and amortization of the cost of internal use software.
	Cost of product revenue consists of purchase and shipment costs for specialty pharmaceuticals and direct sourced medical products.
Selling, General and Administrative Expenses	'
	Selling, general and administrative expenses consist of expenses directly associated with selling and administrative employees and indirect expenses associated with employees that primarily support revenue generating activities (including compensation and benefits) and travel-related expenses, as well as occupancy and other indirect expenses, insurance expenses, professional fees, and other general overhead expenses.
Research and Development Expenses	'
	Research and development expenses consist of employee-related compensation and benefits expenses, and third-party consulting fees of technology professionals, incurred to develop, support and maintain the Company's software-related products and services.
Amortization of Purchased Intangible Assets	'
	Amortization of purchased intangible assets includes the amortization of all identified intangible assets resulting from acquisitions.
Advertising Costs	'
	Advertising costs are expensed as incurred. Advertising costs are reflected in selling, general and administrative expenses in the accompanying consolidated statements of income
Comprehensive Income	'
	Comprehensive income includes all changes in stockholders' equity during a period from non-owner sources. Net income and other comprehensive income, including unrealized gains and losses on investments, are reported, net of their related tax effect, to arrive at comprehensive income.
Basic and Diluted Earnings per Share	'
	Basic earnings per share ("EPS") is calculated by dividing net income by the number of weighted average common shares outstanding during the period. Diluted EPS assumes the conversion, exercise or issuance of all potential common stock equivalents, unless the effect of inclusion would result in the reduction of a loss or the increase in income per share. Diluted EPS is computed by dividing net income by the number of weighted average common shares increased by the dilutive effects of potential common shares outstanding during the period. The number of potential common shares outstanding is determined in accordance with the treasury stock method. Common stock subscribed is included in the calculation of basic EPS, since the subscribed shares have full voting and dividend participation rights on the day of subscription.
Recently Adopted and Issued Accounting Standards	'
	Recently Adopted Accounting Standards
	In February 2013, the FASB issued an ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires presentation of information about significant amounts reclassified from each component of accumulated other comprehensive income, the sources of the items reclassified, and the income statement lines affected, either parenthetically on the face of the financial statements or in the notes to the financial statements. The adoption of this accounting standard during the year ended June 30, 2014 had no significant impact on the Company's consolidated financial statements or related disclosures.
	Recently Issued Accounting Standards
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of the update is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The update 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 update will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is not permitted. The update allows for either full retrospective or modified retrospective adoption. The Company is currently evaluating the transition method that will be elected as well as the impact of the adoption of the update on its consolidated financial statements and related disclosures.

	-1	Reflects net effect on cash and cash equivalents of the receipt of gross proceeds from the IPO of $874.1 million (with an IPO price of $27.00 per share of Class A common stock) and the purchase of units from the member owners described above, as follows (in thousands):
	Gross proceeds from the IPO	$	874,118

	Purchases of Class B common units from the member owners	(543,857		)
	Net cash proceeds from IPO	$	277,814
	-2	Reflects the reduction of prepaid expenses related to the IPO, with an offset to the proceeds of the IPO in additional paid-in capital.
	-3	Premier LP intends to have in effect an election under Section 754 of the Internal Revenue Code of 1986, as amended, or the Code, and comparable elections under state and local tax law, such that the initial sale of Class B common units by PHSI and the member owners will result in adjustments to the tax basis of the assets of Premier LP. These increases in tax basis increase (for tax purposes) the depreciation and amortization deductions by Premier LP, and therefore, reduce the amount of income tax that Premier would otherwise be required to pay in the future. In connection with the Reorganization and IPO, Premier has entered into a tax receivable agreements with the member owners which became effective upon the completion of the Reorganization and IPO, pursuant to which Premier agreed to pay to the member owners, generally over a 15-year period (under current law), 85% of the amount of cash savings, if any, in U.S. federal, foreign, state and local and franchise income tax that Premier actually realizes (or is deemed to realize, in the case of payments required to be made upon certain occurrences under such tax receivable agreements) as a result of the increases in tax basis resulting from the sale or exchange of Class B common units by the member owners. The adjustments give effect to the Section 754 election and the tax receivable agreements based on the following assumptions:
	•	The increase in deferred tax assets representing the income tax effects of the increases in the tax basis as a result of Premier LP's election under Section 754 of the Code in connection with the initial sale of Class B common units described above. This adjustment is calculated based on an effective income tax rate for Premier of approximately 39%, which includes a provision for U.S. federal income taxes and assumes (i) Premier's statutory rates apportioned to each state and local tax jurisdiction, (ii) that there are no material changes in the relevant tax law, and (iii) that Premier earns sufficient taxable income in each year to realize the full tax benefit of the amortization of its assets.
	•	Premier determined the adjustments in connection with the Section 754 election by first calculating the excess of each selling member owner's and PHSI's selling price over such person's share of Premier LP's tax basis in its assets attributable to the Class B common units sold to Premier. Premier then allocated the aggregate excess among Premier LP's assets following applicable tax regulations governing adjustments that result from the Section 754 election. Premier determined each selling member owner's share of the tax basis in Premier LP's assets attributable to the Class B common units sold to Premier by multiplying the member owner's tax capital account balance as of the date of sale as maintained in Premier LP's books and records by a fraction, the numerator of which was the number of Class B common units sold to Premier, and the denominator of which was the number of Class B common units held by the selling member owner immediately prior to the sale. For purposes of the calculation, the selling price per Class B common unit was equal to the net price paid per share of the Class A common stock by the underwriters to Premier in the IPO. The adjustments increased Premier LP's basis in its assets (for tax purposes), and Premier calculates the amount of depreciation, amortization and other deductions to which it is entitled as a result of these adjustments. Premier then calculates Premier's tax liability with and without the deductions attributable to these adjustments, assuming that Premier earns sufficient taxable income in each year to realize the full benefit of the deductions. Premier computed the estimated tax benefit attributable to the election as the excess of Premier's tax liability as so computed without the deductions over Premier's tax liability as so computed with the deductions. Additionally, the tax receivable agreements payments give rise to adjustments that result in Premier LP becoming entitled to additional deductions, and the calculation of Premier's liability under the tax receivable agreements take these adjustments and additional resulting deductions into account.
	•	Premier LP's election under Section 754 of the Code is at the discretion of Premier LP and is not subject to review or approval by the IRS or other tax authorities. The computation of the adjustments resulting from the Section 754 election and Premier's tax liability is subject to audit by the IRS and other tax authorities in the same manner as all other items reported on income tax returns.
	•	Upon the Reorganization and IPO, the cumulative adjustments of $186.1 million, of which $7.0 million was expected to be paid over the next 12 months, and was reflected as a current liability with the remaining balance classified as a long-term liability, to reflect a liability equal to 85% of the estimated realizable tax benefit resulting from the increase in tax basis due to Premier LP's Section 754 election in connection with the initial sale by the member owners of the Class B common units described above as an increase to payable pursuant to the tax receivable agreements.
	•	Deferred tax assets are measured based on the difference in tax basis of Premier's investment in Premier LP as compared to its GAAP carrying value and include the change in allocations in connection with the Reorganization. The adjustments related to Premier LP's Section 754 election described above are a component of Premier's tax basis in Premier LP.
	Pursuant to the terms of the exchange agreement, the member owners and new limited partners admitted to Premier LP following the completion of the IPO may subsequently exchange Class B common units in Premier LP for shares of Premier's Class A common stock, cash or a combination of both. Any subsequent exchanges of Class B common units for shares of Premier's Class A common stock pursuant to the exchange agreement may result in increases in the tax basis of the tangible and intangible assets of Premier LP (85% of the realized tax benefits from which will be due to the limited partners and recorded as an additional payable pursuant to the tax receivable agreements) that otherwise would not have been available. These subsequent exchanges have not been reflected in the consolidated financial statements.
	-4	Reflects the increase in the noncontrolling interest held by the limited partners in Premier LP resulting from the net proceeds from the IPO used to purchase Class A common units from Premier LP of $247.7 million and Class B common units from PHSI of $30.1 million, and the contribution of the common stock of PHSI in connection with the Reorganization of $76.9 million. This is offset by an adjustment of $131.0 million to reflect the approximately 78% controlling interest held by the redeemable limited partners of Premier LP subsequent to the Reorganization and IPO, which is reflected in redeemable limited partners' capital on the unaudited consolidated balance sheets. Immediately following the effective date of the LP Agreement, all of Premier LP's limited partners that approved the Reorganization received Class B common units and capital account balances in Premier LP equal to their percentage interests and capital account balances in Premier LP immediately preceding the Reorganization. Premier used a portion of the net proceeds from the IPO to purchase (i) Class A common units, (ii) Class B common units from PHSI and (iii) Class B common units from the member owners, resulting in a reduction in the noncontrolling interest attributable to the limited partners from 99% to approximately 78%.
	Reflects the increase in redeemable limited partners' capital of $2,575.5 million to record the balance at the redemption amount, which represents the greater of the book value or redemption amount per the LP Agreement, at the date of the Reorganization. This results in an offsetting decrease in retained earnings of $50.1 million, followed by an offsetting decrease in additional paid-in-capital of $173.7 million and with a final offsetting increase in accumulated deficit of $2,351.7 million.
	-5	Reflects (i) the exchange of the existing PHSI shares of common stock, common stock subscribed and related subscriptions receivable for Class B common units, (ii) the issuance of Class B common stock in connection with the Reorganization and (iii) the issuance of Class A common stock in connection with the IPO.
	-6	Reflects the impact of the adjustments in notes (1), (2), (3), (4) and (5) above to additional paid-in capital:
	•	an increase of $96.9 million due to an increase in deferred tax assets described in note (3) of $283.0 million offset by an increase in payables pursuant to the tax receivable agreements of $186.1 million;
	•	an increase of $821.7 million from the net proceeds from the IPO less the par value of the shares of Class A common stock sold in the IPO of $0.3 million and less prepaid offering expenses of $5.9 million;
	•	a decrease of $767.5 million to reflect the difference between the consideration paid to acquire the Class A and B common units and the adjustment to the carrying value of the noncontrolling interest described in note (4) above; and
	•	a decrease in the remaining balance of additional paid-in-capital related to the increase in redeemable limited partners' capital to its redemption value, as described in note (4) above.
	-7	Reflects the decrease in retained earnings and increase in accumulated deficit related to the increase in redeemable limited partners' capital to its redemption value, as described in note (4) above.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]	'
Key assumptions used for determining the fair value of stock options granted	'
	Key assumptions used for determining the fair value of stock options granted were as follows:
	Expected life (1)	6 years
	Expected dividend (2)	—
	Expected volatility (3)	42		%
	Risk-free interest rate (4)	1.71		%
	Weighted average option grant date fair value	$	11.46
	(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 constant maturity market yield as of the date of the grant.

Reflects the reduction of prepaid expenses related to the IPO, with an offset to the proceeds of the IPO in additional paid-in capital.

Premier LP intends to have in effect an election under Section 754 of the Internal Revenue Code of 1986, as amended, or the Code, and comparable elections under state and local tax law, such that the initial sale of Class B common units by PHSI and the member owners will result in adjustments to the tax basis of the assets of Premier LP. These increases in tax basis increase (for tax purposes) the depreciation and amortization deductions by Premier LP, and therefore, reduce the amount of income tax that Premier would otherwise be required to pay in the future. In connection with the Reorganization and IPO, Premier has entered into a tax receivable agreements with the member owners which became effective upon the completion of the Reorganization and IPO, pursuant to which Premier agreed to pay to the member owners, generally over a 15-year period (under current law), 85% of the amount of cash savings, if any, in U.S. federal, foreign, state and local and franchise income tax that Premier actually realizes (or is deemed to realize, in the case of payments required to be made upon certain occurrences under such tax receivable agreements) as a result of the increases in tax basis resulting from the sale or exchange of Class B common units by the member owners. The adjustments give effect to the Section 754 election and the tax receivable agreements based on the following assumptions: b"The increase in deferred tax assets representing the income tax effects of the increases in the tax basis as a result of Premier LP's election under Section 754 of the Code in connection with the initial sale of Class B common units described above. This adjustment is calculated based on an effective income tax rate for Premier of approximately 39%, which includes a provision for U.S. federal income taxes and assumes (i) Premier's statutory rates apportioned to each state and local tax jurisdiction, (ii) that there are no material changes in the relevant tax law, and (iii) that Premier earns sufficient taxable income in each year to realize the full tax benefit of the amortization of its assets. b"Premier determined the adjustments in connection with the Section 754 election by first calculating the excess of each selling member owner's and PHSI's selling price over such person's share of Premier LP's tax basis in its assets attributable to the Class B common units sold to Premier. Premier then allocated the aggregate excess among Premier LP's assets following applicable tax regulations governing adjustments that result from the Section 754 election. Premier determined each selling member owner's share of the tax basis in Premier LP's assets attributable to the Class B common units sold to Premier by multiplying the member owner's tax capital account balance as of the date of sale as maintained in Premier LP's books and records by a fraction, the numerator of which was the number of Class B common units sold to Premier, and the denominator of which was the number of Class B common units held by the selling member owner immediately prior to the sale. For purposes of the calculation, the selling price per Class B common unit was equal to the net price paid per share of the Class A common stock by the underwriters to Premier in the IPO. The adjustments increased Premier LP's basis in its assets (for tax purposes), and Premier calculates the amount of depreciation, amortization and other deductions to which it is entitled as a result of these adjustments. Premier then calculates Premier's tax liability with and without the deductions attributable to these adjustments, assuming that Premier earns sufficient taxable income in each year to realize the full benefit of the deductions. Premier computed the estimated tax benefit attributable to the election as the excess of Premier's tax liability as so computed without the deductions over Premier's tax liability as so computed with the deductions. Additionally, the tax receivable agreements payments give rise to adjustments that result in Premier LP becoming entitled to additional deductions, and the calculation of Premier's liability under the tax receivable agreements take these adjustments and additional resulting deductions into account. b"Premier LP's election under Section 754 of the Code is at the discretion of Premier LP and is not subject to review or approval by the IRS or other tax authorities. The computation of the adjustments resulting from the Section 754 election and Premier's tax liability is subject to audit by the IRS and other tax authorities in the same manner as all other items reported on income tax returns. b"Upon the Reorganization and IPO, the cumulative adjustments of $186.1 million, of which $7.0 million was expected to be paid over the next 12 months, and was reflected as a current liability with the remaining balance classified as a long-term liability, to reflect a liability equal to 85% of the estimated realizable tax benefit resulting from the increase in tax basis due to Premier LP's Section 754 election in connection with the initial sale by the member owners of the Class B common units described above as an increase to payable pursuant to the tax receivable agreements. b"Deferred tax assets are measured based on the difference in tax basis of Premier's investment in Premier LP as compared to its GAAP carrying value and include the change in allocations in connection with the Reorganization. The adjustments related to Premier LP's Section 754 election described above are a component of Premier's tax basis in Premier LP. Pursuant to the terms of the exchange agreement, the member owners and new limited partners admitted to Premier LP following the completion of the IPO may subsequently exchange Class B common units in Premier LP for shares of Premier's Class A common stock, cash or a combination of both. Any subsequent exchanges of Class B common units for shares of Premier's Class A common stock pursuant to the exchange agreement may result in increases in the tax basis of the tangible and intangible assets of Premier LP (85% of the realized tax benefits from which will be due to the limited partners and recorded as an additional payable pursuant to the tax receivable agreements) that otherwise would not have been available. These subsequent exchanges have not been reflected in the consolidated financial statements.

[4]

Reflects the increase in the noncontrolling interest held by the limited partners in Premier LP resulting from the net proceeds from the IPO used to purchase Class A common units from Premier LP of $247.7 million and Class B common units from PHSI of $30.1 million, and the contribution of the common stock of PHSI in connection with the Reorganization of $76.9 million. This is offset by an adjustment of $131.0 million to reflect the approximately 78% controlling interest held by the redeemable limited partners of Premier LP subsequent to the Reorganization and IPO, which is reflected in redeemable limited partners' capital on the unaudited consolidated balance sheets. Immediately following the effective date of the LP Agreement, all of Premier LP's limited partners that approved the Reorganization received Class B common units and capital account balances in Premier LP equal to their percentage interests and capital account balances in Premier LP immediately preceding the Reorganization. Premier used a portion of the net proceeds from the IPO to purchase (i) Class A common units, (ii) Class B common units from PHSI and (iii) Class B common units from the member owners, resulting in a reduction in the noncontrolling interest attributable to the limited partners from 99% to approximately 78%.

[5]

Reflects (i) the exchange of the existing PHSI shares of common stock, common stock subscribed and related subscriptions receivable for Class B common units, (ii) the issuance of Class B common stock in connection with the Reorganization and (iii) the issuance of Class A common stock in connection with the IPO.

[6]

Reflects the impact of the adjustments in notes (1), (2), (3), (4) and (5) above to additional paid-in capital: b"an increase of $96.9 million due to an increase in deferred tax assets described in note (3) of $283.0 million offset by an increase in payables pursuant to the tax receivable agreements of $186.1 million; b"an increase of $821.7 million from the net proceeds from the IPO less the par value of the shares of Class A common stock sold in the IPO of $0.3 million and less prepaid offering expenses of $5.9 million; b"a decrease of $767.5 million to reflect the difference between the consideration paid to acquire the Class A and B common units and the adjustment to the carrying value of the noncontrolling interest described in note (4) above; andb"a decrease in the remaining balance of additional paid-in-capital related to the increase in redeemable limited partners' capital to its redemption value, as described in note (4) above.

[7]

Reflects the decrease in retained earnings and increase in accumulated deficit related to the increase in redeemable limited partners' capital to its redemption value, as described in note (4) above.

Reflects the increase in the noncontrolling interest held by the limited partners in Premier LP resulting from the net proceeds from the IPO used to purchase Class A common units from Premier LP of $247.7 million and Class B common units from PHSI of $30.1 million, and the contribution of the common stock of PHSI in connection with the Reorganization of $76.9 million. This is offset by an adjustment of $131.0 million to reflect the approximately 78% controlling interest held by the redeemable limited partners of Premier LP subsequent to the Reorganization and IPO, which is reflected in redeemable limited partners' capital on the unaudited consolidated balance sheets. Immediately following the effective date of the LP Agreement, all of Premier LP's limited partners that approved the Reorganization received Class B common units and capital account balances in Premier LP equal to their percentage interests and capital account balances in Premier LP immediately preceding the Reorganization. Premier used a portion of the net proceeds from the IPO to purchase (i) Class A common units, (ii) Class B common units from PHSI and (iii) Class B common units from the member owners, resulting in a reduction in the noncontrolling interest attributable to the limited partners from 99% to approximately 78%.

[2]

Operating results for the third quarter of fiscal year ended June 30, 2014 reflect the gain on sale of investment in GHX.

[3]

Operating results for the second quarter of fiscal year ended June 30, 2014 reflect the completion of the Reorganization and IPO, including the significant adjustment of redeemable limited partners' capital to redemption amount.

[4]

Operating results for the first quarter of fiscal year ended June 30, 2014 differ significantly from subsequent periods, which reflect the impact of the Reorganization and IPO, which occurred in the second quarter of fiscal year ended June 30, 2014.

[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 constant maturity market yield as of the date of the grant.

[1]	Premier LP intends to have in effect an election under Section 754 of the Internal Revenue Code of 1986, as amended, or the Code, and comparable elections under state and local tax law, such that the initial sale of Class B common units by PHSI and the member owners will result in adjustments to the tax basis of the assets of Premier LP. These increases in tax basis increase (for tax purposes) the depreciation and amortization deductions by Premier LP, and therefore, reduce the amount of income tax that Premier would otherwise be required to pay in the future. In connection with the Reorganization and IPO, Premier has entered into a tax receivable agreements with the member owners which became effective upon the completion of the Reorganization and IPO, pursuant to which Premier agreed to pay to the member owners, generally over a 15-year period (under current law), 85% of the amount of cash savings, if any, in U.S. federal, foreign, state and local and franchise income tax that Premier actually realizes (or is deemed to realize, in the case of payments required to be made upon certain occurrences under such tax receivable agreements) as a result of the increases in tax basis resulting from the sale or exchange of Class B common units by the member owners. The adjustments give effect to the Section 754 election and the tax receivable agreements based on the following assumptions: b"The increase in deferred tax assets representing the income tax effects of the increases in the tax basis as a result of Premier LP's election under Section 754 of the Code in connection with the initial sale of Class B common units described above. This adjustment is calculated based on an effective income tax rate for Premier of approximately 39%, which includes a provision for U.S. federal income taxes and assumes (i) Premier's statutory rates apportioned to each state and local tax jurisdiction, (ii) that there are no material changes in the relevant tax law, and (iii) that Premier earns sufficient taxable income in each year to realize the full tax benefit of the amortization of its assets. b"Premier determined the adjustments in connection with the Section 754 election by first calculating the excess of each selling member owner's and PHSI's selling price over such person's share of Premier LP's tax basis in its assets attributable to the Class B common units sold to Premier. Premier then allocated the aggregate excess among Premier LP's assets following applicable tax regulations governing adjustments that result from the Section 754 election. Premier determined each selling member owner's share of the tax basis in Premier LP's assets attributable to the Class B common units sold to Premier by multiplying the member owner's tax capital account balance as of the date of sale as maintained in Premier LP's books and records by a fraction, the numerator of which was the number of Class B common units sold to Premier, and the denominator of which was the number of Class B common units held by the selling member owner immediately prior to the sale. For purposes of the calculation, the selling price per Class B common unit was equal to the net price paid per share of the Class A common stock by the underwriters to Premier in the IPO. The adjustments increased Premier LP's basis in its assets (for tax purposes), and Premier calculates the amount of depreciation, amortization and other deductions to which it is entitled as a result of these adjustments. Premier then calculates Premier's tax liability with and without the deductions attributable to these adjustments, assuming that Premier earns sufficient taxable income in each year to realize the full benefit of the deductions. Premier computed the estimated tax benefit attributable to the election as the excess of Premier's tax liability as so computed without the deductions over Premier's tax liability as so computed with the deductions. Additionally, the tax receivable agreements payments give rise to adjustments that result in Premier LP becoming entitled to additional deductions, and the calculation of Premier's liability under the tax receivable agreements take these adjustments and additional resulting deductions into account. b"Premier LP's election under Section 754 of the Code is at the discretion of Premier LP and is not subject to review or approval by the IRS or other tax authorities. The computation of the adjustments resulting from the Section 754 election and Premier's tax liability is subject to audit by the IRS and other tax authorities in the same manner as all other items reported on income tax returns. b"Upon the Reorganization and IPO, the cumulative adjustments of $186.1 million, of which $7.0 million was expected to be paid over the next 12 months, and was reflected as a current liability with the remaining balance classified as a long-term liability, to reflect a liability equal to 85% of the estimated realizable tax benefit resulting from the increase in tax basis due to Premier LP's Section 754 election in connection with the initial sale by the member owners of the Class B common units described above as an increase to payable pursuant to the tax receivable agreements. b"Deferred tax assets are measured based on the difference in tax basis of Premier's investment in Premier LP as compared to its GAAP carrying value and include the change in allocations in connection with the Reorganization. The adjustments related to Premier LP's Section 754 election described above are a component of Premier's tax basis in Premier LP. Pursuant to the terms of the exchange agreement, the member owners and new limited partners admitted to Premier LP following the completion of the IPO may subsequently exchange Class B common units in Premier LP for shares of Premier's Class A common stock, cash or a combination of both. Any subsequent exchanges of Class B common units for shares of Premier's Class A common stock pursuant to the exchange agreement may result in increases in the tax basis of the tangible and intangible assets of Premier LP (85% of the realized tax benefits from which will be due to the limited partners and recorded as an additional payable pursuant to the tax receivable agreements) that otherwise would not have been available. These subsequent exchanges have not been reflected in the consolidated financial statements.
