(the “Company”) develops and operates inpatient psychiatric facilities, residential treatment centers, group homes, substance abuse facilities and facilities providing outpatient behavioral healthcare services to serve the behavioral health and recovery needs of communities throughout the United States (U.S.), the United Kingdom (U.K.) and Puerto Rico. At September 30, 2016, the Company operated 589 behavioral healthcare facilities with approximately 17,900 beds in 39 states, the U.K. and Puerto Rico. Basis of Presentation The business of the Company is conducted through limited liability companies, C-corporations and, for the U.K. facilities, their foreign counterparts. The Company’s consolidated financial statements include the accounts of the Company and all subsidiaries controlled by the Company through its’ direct or indirect ownership of majority interests and exclusive rights granted to the Company as the controlling member of an entity. All intercompany accounts and transactions have been eliminated in consolidation. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for fair presentation of our financial position and results of operations have been included. The Company’s fiscal year ends on December 31 and interim results are not necessarily indicative of results for a full year or any other interim period. The condensed consolidated balance sheet at December 31, 2015 has been derived from the audited financial statements as of that date. The information contained in these condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto for the fiscal year ended December 31, 2015 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 25, 2016. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Certain reclassifications have been made to prior years to conform to the current year presentation.

Approximately 0.3 million and 0.9 million shares of common stock issuable upon exercise of outstanding stock option awards were excluded from the calculation of diluted earnings per share for the three and nine months ended September 30, 2015, respectively, because their effect would have been anti-dilutive.

On May 1, 2016, the Company completed the acquisition of TrustPoint Hospital (“TrustPoint”), an inpatient psychiatric facility with 100 beds located in Murfreesboro, Tennessee, for cash consideration of approximately $62.7 million. On April 1, 2016, the Company completed the acquisition of Serenity Knolls (“Serenity Knolls”), an inpatient psychiatric facility with 30 beds located in Forrest Knolls, California, for cash consideration of approximately $9.7 million.

Priory is the leading independent provider of behavioral healthcare services in the U.K. At February 16, 2016, Priory operated 324 facilities with approximately 7,100 beds. Planned U.K. Divestiture The Competition and Markets Authority (the “CMA”) in the U.K. has been reviewing the Company’s acquisition of Priory. On July 14, 2016, the CMA announced that the Company’s acquisition of Priory will be referred for a phase 2 investigation unless the Company offered acceptable undertakings to address the CMA’s competition concerns relating to the provision of behavioral healthcare services in certain markets. On July 28, 2016, the CMA announced that the Company had offered undertakings to address the CMA’s concerns and that, in lieu of a phase 2 investigation, the CMA would consider the Company’s undertakings. On October 18, 2016, the Company signed a definitive agreement with BC Partners (“BC Partners”) for the sale of 21 existing U.K. behavioral health facilities and one de novo behavioral health facility with an aggregate of approximately 1,000 beds (collectively, the “U.K. Disposal Group”). The Company’s management believes that the planned divestiture addresses the CMA’s competition concerns. The Company expects the sale to be approved by the CMA on or before November 18, 2016 and expects to complete the sale shortly thereafter. If the sale is approved by the CMA and completed, the Company will receive £320 million cash for the sale. If the sale is not approved by the CMA, the Company expects that the CMA will proceed with a phase 2 investigation. In conjunction with the planned divestiture, the Company recorded $389.7 million as assets held for sale on the condensed consolidated balance sheet at September 30, 2016 and a loss on divestiture of $174.7 million in the condensed consolidated statements of operations for the three and nine months ended September 30, 2016. The loss on divestiture consisted of an allocation of goodwill to the U.K. Disposal Group of $106.9 million, estimated transaction-related expenses of $25.6 million and loss on the sale of properties of $42.2 million. The Company is required to measure assets held for sale at the lower of its carrying value or fair value less cost to sell. The allocation of goodwill was based on the fair value of the U.K. Disposal Group relative to the total fair value of the Company’s U.K. Facilities segment. The condensed consolidated statements of operations for the three and nine months ended September 30, 2016 include revenue of $45.6 million and $125.1 million, respectively, and income from continuing operations before income taxes of $3.2 million and $12.2 million, respectively, related to the U.K. Disposal Group excluding the loss on divestiture.

On December 31, 2012, the Company entered into an Amended and Restated Credit Agreement (the “Amended and Restated Credit Agreement”) which amended and restated the Senior Secured Credit Facility (the “Amended and Restated Senior Credit Facility”). The Company has amended the Amended and Restated Credit Agreement from time to time as described in the Company’s prior filings with the Securities and Exchange Commission. On February 6, 2015, the Company entered into a Seventh Amendment (the “Seventh Amendment”) to the Amended and Restated Credit Agreement. The Seventh Amendment added Citibank, N.A. as an “L/C Issuer” under the Amended and Restated Credit Agreement in order to permit the rollover of CRC’s existing letters of credit into the Amended and Restated Credit Agreement and increased both the Company’s Letter of Credit Sublimit and Swing Line Sublimit to $20.0 million. On February 11, 2015, the Company entered into a First Incremental Facility Amendment (the “First Incremental Amendment”) to the Amended and Restated Credit Agreement. The First Incremental Amendment activated a new $500.0 million incremental Term Loan B facility (the “Existing TLB Facility”) that was added to the Amended and Restated Senior Credit Facility, subject to limited conditionality provisions. Borrowings under the Existing TLB Facility were used to fund a portion of the purchase price for the acquisition of CRC. On April 22, 2015, the Company entered into an Eighth Amendment (the “Eighth Amendment”) to the Amended and Restated Credit Agreement. The Eighth Amendment changed the definition of “Change of Control” in part to remove a provision whose purpose was, when calculating whether a majority of incumbent directors have approved new directors, that any incumbent director that became a director as a result of a threatened or actual proxy contest was not counted in such calculation. On January 25, 2016, the Company entered into the Ninth Amendment (the “Ninth Amendment”) to the Amended and Restated Credit Agreement. The Ninth Amendment modifies certain definitions and provides increased flexibility to the Company in terms of its financial covenants. The Company’s baskets for permitted investments were also increased to provide increased flexibility for it to invest in non-wholly owned subsidiaries, joint ventures and foreign subsidiaries. The Company may now invest in non-wholly owned subsidiaries and joint ventures up to 10.0% of the Company and its subsidiaries’ total assets in any four consecutive fiscal quarter period, and up to 12.5% of the Company and its subsidiaries’ total assets during the term of the Amended and Restated Credit Agreement. The Company may also invest in foreign subsidiaries that are not loan parties up to 10% of the Company and its subsidiaries’ total assets in any consecutive four fiscal quarter period, and up to 15% of the Company and its subsidiaries’ total assets during the term of the Amended and Restated Credit Agreement. The foregoing permitted investments are subject to an aggregate cap of 25% of the Company and its subsidiaries’ total assets in any fiscal year. On February 16, 2016, the Company entered into a Second Incremental Facility Amendment (the “Second Incremental Amendment”) to the Amended and Restated Credit Agreement. The Second Incremental Amendment activated a new $955.0 million incremental Term Loan B facility (the “New TLB Facility”) and added $135.0 million to the Term Loan A facility (the “TLA Facility”) to the Amended and Restated Senior Credit Facility, subject to limited conditionality provisions. Borrowings under the New TLB Facility were used to fund a portion of the purchase price for the acquisition of Priory and the fees and expenses for such acquisition and the related financing transactions. Borrowings under the TLA Facility were used to pay down the majority of our $300.0 million revolving credit facility. On May 26, 2016, the Company entered into a Tranche B-1 Repricing Amendment (the “Tranche B-1 Repricing Amendment”) to the Amended and Restated Credit Agreement. The Tranche B-1 Repricing Amendment reduces the Applicable Rate with respect to the Existing TLB Facility from 3.5% to 3.0% in the case of Eurodollar Rate loans and 2.5% to 2.0% in the case of Base Rate Loans. On September 21, 2016, the Company entered into a Tranche B-2 Repricing Amendment (the “Tranche B-2 Repricing Amendment”) to the Amended and Restated Credit Agreement. The Tranche B-2 Repricing Amendment reduces the Applicable Rate with respect to the New TLB Facility from 3.75% to 3.0% in the case of Eurodollar Rate loans and 2.75% to 2.0% in the case of Base Rate Loans. In connection with the Tranche B-2 Repricing Amendment, the Company recorded a debt extinguishment charge of $3.4 million, including the discount and write-off of deferred financing costs, which was recorded in debt extinguishment costs in the condensed consolidated statements of income. The Company had $120.6 million of availability under the revolving line of credit as of September 30, 2016. Borrowings under the revolving line of credit are subject to customary conditions precedent to borrowing. The Amended and Restated Credit Agreement requires quarterly term loan principal repayments of our TLA Facility of $12.6 million for September 30, 2016 to December 31, 2016, $16.8 million for March 31, 2017 to December 31, 2017, and $20.9 million for March 31, 2018 to December 31, 2018, with the remaining principal balance of the TLA Facility due on the maturity date of February 13, 2019. The Company is required to repay the Existing TLB Facility in equal quarterly installments of $1.3 million on the last business day of each March, June, September and December, with the outstanding principal balance of the Existing TLB Facility due on February 11, 2022. The Company is required to repay the New TLB Facility in equal quarterly installments of approximately $2.4 million on the last business day of each March, June, September and December, with the outstanding principal balance of the TLB Facility due on February 16, 2023. Borrowings under the Amended and Restated Senior Credit Facility are guaranteed by each of the Company’s wholly-owned domestic subsidiaries (other than certain excluded subsidiaries) and are secured by a lien on substantially all of the assets of the Company and such subsidiaries. Borrowings with respect to the TLA Facility and the Company’s revolving credit facility (collectively, “Pro Rata Facilities”) under the Amended and Restated Credit Agreement bear interest at a rate tied to Acadia’s Consolidated Leverage Ratio (defined as consolidated funded debt net of up to $40.0 million of unrestricted and unencumbered cash to consolidated EBITDA, in each case as defined in the Amended and Restated Credit Agreement). The Applicable Rate (as defined in the Amended and Restated Credit Agreement) for the Pro Rata Facilities was 3.25% for Eurodollar Rate Loans (as defined in the Amended and Restated Credit Agreement) and 2.25% for Base Rate Loans (as defined in the Amended and Restated Credit Agreement) at September 30, 2016. Eurodollar Rate Loans with respect to the Pro Rata Facilities bear interest at the Applicable Rate plus the Eurodollar Rate (as defined in the Amended and Restated Credit Agreement) (based upon the LIBOR Rate (as defined in the Amended and Restated Credit Agreement) prior to commencement of the interest rate period). Base Rate Loans with respect to the Pro Rata Facilities bear interest at the Applicable Rate plus the highest of (i) the federal funds rate plus 0.50%, (ii) the prime rate and (iii) the Eurodollar Rate plus 1.0%. As of September 30, 2016, the Pro Rata Facilities bore interest at a rate of LIBOR plus 3.25%. In addition, the Company is required to pay a commitment fee on undrawn amounts under the revolving line of credit. The Amended and Restated Credit Agreement requires the Company and its subsidiaries to comply with customary affirmative, negative and financial covenants, including a fixed charge coverage ratio, consolidated leverage ratio and senior secured leverage ratio. The Company may be required to pay all of its indebtedness immediately if it defaults on any of the numerous financial or other restrictive covenants contained in any of its material debt agreements. As of September 30, 2016, the Company was in compliance with such covenants. Senior Notes 6.125% Senior Notes due 2021 On March 12, 2013, the Company issued $150.0 million of 6.125% Senior Notes due 2021 (the “6.125% Senior Notes”). The 6.125% Senior Notes mature on March 15, 2021 and bear interest at a rate of 6.125% per annum, payable semi-annually in arrears on March 15 and September 15 of each year. 5.125% Senior Notes due 2022 On July 1, 2014, the Company issued $300.0 million of 5.125% Senior Notes due 2022 (the “5.125% Senior Notes”). The 5.125% Senior Notes mature on July 1, 2022 and bear interest at a rate of 5.125% per annum, payable semi-annually in arrears on January 1 and July 1 of each year. 5.625% Senior Notes due 2023 On February 11, 2015, the Company issued $375.0 million of 5.625% Senior Notes due 2023 (the “5.625% Senior Notes”). The 5.625% Senior Notes mature on February 15, 2023 and bear interest at a rate of 5.625% per annum, payable semi-annually in arrears on February 15 and August 15 of each year. On September 21, 2015, the Company issued $275.0 million of additional 5.625% Senior Notes. The additional notes form a single class of debt securities with the existing 5.625% Senior Notes. Giving effect to this issuance, the Company has outstanding an aggregate of $650.0 million of 5.625% Senior Notes. 6.500% Senior Notes due 2024 On February 16, 2016, the Company issued $390.0 million of 6.500% Senior Notes due 2024 (the “6.500% Senior Notes”). The 6.500% Senior Notes mature on March 1, 2024 and bear interest at a rate of 6.500% per annum, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on September 1, 2016. The indentures governing the 6.125% Senior Notes, 5.125% Senior Notes, 5.625% Senior Notes and 6.500% Senior Notes (together, the “Senior Notes”) contain covenants that, among other things, limit the Company’s ability and the ability of its restricted subsidiaries to: (i) pay dividends, redeem stock or make other distributions or investments; (ii) incur additional debt or issue certain preferred stock; (iii) transfer or sell assets; (iv) engage in certain transactions with affiliates; (v) create restrictions on dividends or other payments by the restricted subsidiaries; (vi) merge, consolidate or sell substantially all of the Company’s assets; and (vii) create liens on assets. The Senior Notes issued by the Company are guaranteed by each of the Company’s subsidiaries that guarantee the Company’s obligations under the Amended and Restated Senior Credit Facility. The guarantees are full and unconditional and joint and several. The Company may redeem the Senior Notes at its option, in whole or part, at the dates and amounts set forth in the indentures. 9.0% and 9.5% Revenue Bonds On November 11, 2012, in connection with the acquisition of Park Royal, the Company assumed debt of $23.0 million. The fair market value of the debt assumed was $25.6 million and resulted in a debt premium balance being recorded as of the acquisition date. The debt consisted of $7.5 million and $15.5 million of Lee County (Florida) Industrial Development Authority Healthcare Facilities Revenue Bonds, Series 2010 with stated interest rates of 9.0% and 9.5% (“9.0% and 9.5% Revenue Bonds”), respectively. The 9.0% bonds in the amount of $7.5 million have a maturity date of December 1, 2030 and require yearly principal payments beginning in 2013. The 9.5% bonds in the amount of $15.5 million have a maturity date of December 1, 2040 and require yearly principal payments beginning in 2031. The principal payments establish a bond sinking fund to be held with the trustee and shall be sufficient to redeem the principal amounts of the 9.0% and 9.5% Revenue Bonds on their respective maturity dates. As of September 30, 2016 and December 31, 2015, $2.3 million was recorded within other assets on the condensed consolidated balance sheets related to the debt service reserve fund requirements. The yearly principal payments, which establish a bond sinking fund, will increase the debt service reserve fund requirements. The bond premium amount of $2.6 million is amortized as a reduction of interest expense over the life of the revenue bonds using the effective interest method.

The following table summarizes the grant-date fair value of options and the assumptions used to develop the fair value estimates for options granted during the nine months ended September 30, 2016 and year ended December 31, 2015: September 30, 2016 December 31, 2015 Weighted average grant-date fair value of options $ 19.35 $ 21.78 Risk-free interest rate 1.3 % 1.5 % Expected volatility 33 % 35 % Expected life (in years) 5.5 5.5 The Company’s estimate of expected volatility for stock options is based upon the volatility of guideline companies given the lack of sufficient historical trading experience of the Company’s common stock. The risk-free interest rate is the approximate yield on United States Treasury Strips having a life equal to the expected option life on the date of grant. The expected life is an estimate of the number of years an option will be held before it is exercised.

Income Taxes	9. Income Taxes The provision for income taxes for continuing operations for the three months ended September 30, 2016 and 2015 reflects effective tax rates of (2.1)% and 30.4%, respectively. The provision for income taxes for continuing operations for the nine months ended September 30, 2016 and 2015 reflects effective tax rates of (292.8)% and 31.0%, respectively. The change in the tax rate for the three and nine months ended September 30, 2016 is primarily attributable to the loss on divestiture related to our planned divestiture in the U.K.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	10. Derivative Instruments The Company entered into foreign currency forward contracts during the three and nine months ended September 30, 2016 and 2015 in connection with (i) acquisitions in the U.K. and (ii) transfers of cash between the U.S. and U.K. under the Company’s cash management and foreign currency risk management programs. Foreign currency forward contracts limit the economic risk of changes in the exchange rate between US Dollars (“USD”) and British Pounds (“GBP”) associated with cash transfers. These foreign currency forward contracts did not meet the hedge accounting criteria under Accounting Standards Codification 815, Derivatives and Hedging In May 2016, the Company entered into multiple cross currency swap agreements with an aggregate notional amount of $650.0 million to manage foreign currency risk by effectively converting a portion of its fixed-rate USD-denominated senior notes, including the semi-annual interest payments thereunder, to fixed-rate GBP-denominated debt of £449.3 million. The senior notes effectively converted include $150.0 million aggregate principal amount of 6.125% Senior Notes, $300.0 million aggregate principal amount of 5.125% Senior Notes and $200.0 million aggregate principal amount of 5.625% Senior Notes. During the term of the swap agreements, the Company will receive semi-annual interest payments in USD from the counterparties at fixed interest rates, and the Company will make semi-annual interest payments in GBP to the counterparties at fixed interest rates. The interest payments under the cross-currency swap agreements result in £24.7 million of annual cash flows, from the Company’s U.K. business being converted to $35.8 million (at a 1.45 exchange rate). The interest rates applicable to the GBP interest payments are substantially the same as the interest rates in place for the existing USD-denominated debt. At maturity, the Company will repay the principal amounts listed above in GBP and receive the principal amount in USD. The Company has designated the cross currency swap agreements as qualifying hedging instruments and is accounting for these as net investment hedges. The fair value of the cross currency swap agreements of $49.9 million is recorded as an asset within derivative instruments on the condensed consolidated balance sheets. The gains and losses resulting from fair value adjustments to the cross currency swap agreements are recorded in accumulated other comprehensive income as the swaps are effective in hedging the designated risk. Cash flows related to the cross currency swaps are included in operating activities in the condensed consolidated statements of cash flows.

Fair values were based on trading activity among the Company’s lenders and the average bid and ask price as determined using published rates. The fair values of the derivative instruments were categorized as Level 2 in the GAAP fair value hierarchy and were based on observable market inputs including applicable exchange rates and interest rates. The fair value of the contingent consideration liabilities were categorized as Level 3 in the GAAP fair value hierarchy. The contingent consideration liabilities were valued using a probability-weighted discounted cash flow method. This analysis reflected the contractual terms of the purchase agreements and utilized assumptions with regard to future earnings, probabilities of achieving such future earnings and a discount rate.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	13. Noncontrolling Interests On May 2, 2016, the Company opened Crestwyn Behavioral Health, a de novo inpatient psychiatric facility located in Memphis, Tennessee. The Company owns 60% of the equity interests in the facility, and two noncontrolling partners each own 20%. The value of the 40% noncontrolling interests approximates $6.0 million and is based on the fair value of contributions. The Company consolidates the operations of the facility based on its 60% equity ownership and its control of the entity. The noncontrolling interests are reflected as redeemable noncontrolling interests on the accompanying condensed consolidated balance sheets based on a put right that could require the Company to purchase the noncontrolling interests upon the occurrence of a change in control. On August 31, 2015, the Company completed the acquisition of a controlling interest in Southcoast, an inpatient psychiatric facility located in Fairhaven, Massachusetts. The Company owns 75% of the equity interests in the facility. The value of the 25% noncontrolling interest approximates $9.2 million. The Company considered an income approach and other valuation methodologies to value the noncontrolling interests. The Company consolidates the operations of the facility based on its 75% equity ownership and its control of the entity.

The Company uses Segment EBITDA as an analytical indicator to measure the performance of the Company’s segments and to develop strategic objectives and operating plans for those segments. Segment EBITDA is commonly used as an analytical indicator within the health care industry, and also serves as a measure of leverage capacity and debt service ability. Segment EBITDA should not be considered as a measure of financial performance under generally accepted accounting principles, and the items excluded from Segment EBITDA are significant components in understanding and assessing financial performance. Because Segment EBITDA is not a measurement determined in accordance with generally accepted accounting principles and is thus susceptible to varying calculations, Segment EBITDA, as presented, may not be comparable to other similarly titled measures of other companies. (2) Assets include property and equipment for the U.S. Facilities of $1.0 billion, U.K. Facilities of $1.7 billion and corporate and other of $33.1 million at September 30, 2016. Assets include property and equipment for the U.S. Facilities of $832.2 million, U.K. Facilities of $824.4 million and corporate and other of $52.4 million at December 31, 2015.

The Company may also invest in foreign subsidiaries that are not loan parties up to 10% of the Company and its subsidiaries’ total assets in any consecutive four fiscal quarter period, and up to 15% of the Company and its subsidiaries’ total assets during the term of the Amended and Restated Credit Agreement. The foregoing permitted investments are subject to an aggregate cap of 25% of the Company and its subsidiaries’ total assets in any fiscal year.
