Accounting Policies [Abstract]
Background and Summary of Significant Accounting Policies	1. BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business – Advanced Drainage Systems, Inc. and subsidiaries (collectively referred to as “ADS” or the “Company”), incorporated in Delaware, designs, manufactures and markets high performance thermoplastic corrugated pipe and related water management products, primarily in North and South America and Europe. ADS’s broad product line includes corrugated high density polyethylene (or “HDPE”) pipe, polypropylene (or “PP”) pipe and related water management products. The Company is managed based primarily on the geographies in which it operates and reports results of operations in two reportable segments: Domestic and International. Historically, sales of the Company’s products have been higher in the first and second quarters of each fiscal year due to favorable weather and longer daylight conditions accelerating construction activity during these periods. Seasonal variations in operating results may also be impacted by inclement weather conditions, such as cold or wet weather, which can delay projects. Basis of Presentation – The Company prepares its Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The Condensed Consolidated Balance Sheet as of March 31, 2017 was derived from audited financial statements included in the Annual Report on Form 10-K for the year ended March 31, 2017 (“Fiscal 2017 Form 10-K”). The accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments, of a normal recurring nature, necessary to present fairly its financial position as of June 30, 2017 and the results of operations and cash flows for the three months ended June 30, 2017 and 2016. The interim Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements, including the notes thereto, filed in the Company’s Fiscal 2017 Form 10-K. Principles of Consolidation – The Condensed Consolidated Financial Statements include the Company, its wholly-owned subsidiaries, its majority-owned subsidiaries and variable interest entities (“VIEs”) of which the Company is the primary beneficiary. The Company uses the equity method of accounting for equity investments where it exercises significant influence but does not hold a controlling financial interest. Such investments are recorded in Other assets in the Condensed Consolidated Balance Sheets and the related equity earnings from these investments are included in Equity in net loss (income) of unconsolidated affiliates in the Condensed Consolidated Statements of Operations. All intercompany balances and transactions have been eliminated in consolidation. Recent Accounting Guidance Recently Adopted Accounting Guidance Measurement of Inventory – In July 2015, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) which requires entities to measure most inventory at the lower of cost and net realizable value, simplifying current guidance under which an entity must measure inventory at the lower of cost or market. The determination of market value, under current guidance, is considered unnecessarily complex as there are several potential outcomes based on its definition as replacement cost, net realizable value, or net realizable value less an approximate normal profit margin. Whereas net realizable value, under the update, is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This update is effective for annual periods beginning on or after December 15, 2016, and interim periods within those years, with early adoption permitted. The Company adopted this standard effective April 1, 2017. The new standard did not have a material impact on the Condensed Consolidated Financial Statements. Stock-Based Compensation – In March 2016, the FASB issued an ASU which is intended to simplify certain aspects of the accounting for stock-based compensation. The Company adopted the standard on April 1, 2017. The adoption of the ASU did not have a material impact on the historical consolidated financial statements. This update contains changes to the accounting for excess tax benefits, whereby excess tax benefits will be recognized in the income statement rather than in additional paid-in capital on the balance sheet. This update is expected to result in increased volatility to income tax expense in future periods dependent upon the timing of employee exercises of stock options, the price of the Company's common stock and the vesting of restricted stock awards. In addition, excess tax benefits will now be classified as operating cash flows rather than financing cash flows in the Consolidated Statements of Cash Flows. The amendment also contains potential changes to the accounting for forfeitures, whereby entities can elect to either continue to apply the current requirement to estimate forfeitures when determining compensation expense, or to alternatively reverse the compensation expense of forfeited awards when they occur. The Company will account for forfeitures as they occur, which may result in expense volatility based on the timing of forfeitures. In addition, the update also modified the net-share settlement liability classification exception for statutory income tax withholdings, whereby the new guidance allows an employer with a statutory income tax withholding obligation to withhold shares with a fair value up to the maximum statutory tax rate in the employee’s applicable jurisdiction. The Company included this provision in awards issued in fiscal 2017 and modified previously issued awards on April 1, 2017. See “Note 10. Stock-Based Compensation” for further information on the modification. Definition of a Business – In January 2017, the FASB issued an ASU to clarify the definition of a business. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The amendments are intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments provide a more robust framework to use in determining when a set of assets and activities is a business. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company adopted this standard effective April 1, 2018. The new standard did not have a material impact on the Condensed Consolidated Financial Statements. Recent Accounting Guidance Not Yet Adopted Revenue Recognition – In May 2014, the FASB issued an ASU which amends the guidance for revenue recognition. This standard contains principles that will require an entity to recognize revenue to depict the transfer of goods and services to customers at an amount that an entity expects to be entitled to in exchange for goods or services. The standard sets forth a new revenue recognition model that requires identifying the contract, identifying the performance obligations and recognizing the revenue upon satisfaction of performance obligations. In August 2015, the FASB issued an ASU that deferred the effective date of the new revenue standard for public entities to periods beginning after December 15, 2017, with early adoption permitted but not earlier than the original effective date of periods beginning after December 15, 2016. There have also been various additional accounting standards updates issued by the FASB in 2016 that further amend this new revenue standard. The updated standard permits the use of either the retrospective or cumulative effect transition method. The Company expects to adopt this standard effective April 1, 2018. The Company has not yet selected a transition method and is currently evaluating the impact of this standard on the consolidated financial statements. Leases – In February 2016, the FASB issued an ASU which amends the guidance for leases. This standard contains principles that will require an entity to recognize most leases on the balance sheet by recording a right-of-use asset and a lease liability, unless the lease is a short-term lease that has an accounting lease term of twelve months or less. The standard also contains other changes to the current lease guidance that may result in changes to how entities determine which contractual arrangements qualify as a lease, the accounting for executory costs such as property taxes and insurance, as well as which lease origination costs will be capitalizable. The new standard also requires expanded quantitative and qualitative disclosures. This standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those years, and early adoption is permitted. The standard requires the use of the modified retrospective transition method, whereby the new guidance will be applied at the beginning of the earliest period presented in the financial statements of the period of adoption. The modified retrospective transition approach includes certain practical expedients that entities may elect to apply in transition. The Company expects to adopt this standard effective April 1, 2019. The Company has not yet determined whether to apply any of the available practical expedients. The Company has begun the process of reviewing contracts under the new standard to determine the impact the new standard will have on the consolidated financial statements. The Company is also in process of implementing a new software solution to improve the process of accounting for leases under the current and new standard. Measurement of Credit Losses – In June 2016, the FASB issued an ASU which provides amended guidance on the measurement of credit losses on financial instruments, including trade receivables. This standard requires the use of an impairment model referred to as the current expected credit loss model. This standard is effective for fiscal years beginning after December 15, 2019, including interim periods within those years, and early adoption is permitted for fiscal years beginning after December 15, 2018. The Company expects to adopt this standard effective April 1, 2020. The Company is currently evaluating the impact of this standard on the consolidated financial statements. Cash Flow Classification – In August 2016, the FASB issued an ASU which provides amended guidance on the classification of certain cash receipts and cash payments in the statement of cash flows, including related to debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance and distributions received from equity method investees. This update is effective for fiscal years beginning after December 15, 2017, including interim periods within those years, and early adoption is permitted. This amended guidance must be applied retrospectively to all periods presented, but may be applied prospectively if retrospective application would be impracticable. The Company expects to adopt this update effective April 1, 2018. The Company is currently evaluating the impact of this update on the consolidated financial statements. Goodwill Impairment – In January 2017, the FASB issued an ASU which removes the requirement to compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. As a result, under the standards update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments are effect for annual periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company expects to adopt this standard effective April 1, 2020. The Company is currently evaluating the impact of this standard on the consolidated financial statements. Stock-Based Compensation – In May 2017, the FASB issued an ASU to clarify when modification accounting should be applied for changes to the terms or conditions of share-based payment awards. The amendments clarify that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company expects to adopt this standard effective April 1, 2018. The Company is currently evaluating the impact of this update on its consolidated financial statements. With the exception of the pronouncements described above, there have been no new accounting pronouncements issued or adopted since the filing of the Fiscal 2017 Form 10-K that have significance, or potential significance, to the Condensed Consolidated Financial Statements.

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	4. When applying fair value principles in the valuation of assets and liabilities, the Company is required to maximize the use of quoted market prices and minimize the use of unobservable inputs. The Company has not changed its valuation techniques used in measuring the fair value of any financial assets or liabilities during the fiscal years presented. The fair value estimates take into consideration the credit risk of both the Company and its counterparties. When active market quotes are not available for financial assets and liabilities, ADS uses industry standard valuation models. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including credit risk, interest rate curves, foreign currency rates and forward and spot prices for currencies. In circumstances where market-based observable inputs are not available, management judgment is used to develop assumptions to estimate fair value. Generally, the fair value of Level 3 instruments is estimated as the net present value of expected future cash flows based on internal and external inputs. Recurring Fair Value Measurements - The assets and liabilities carried at fair value as of the periods presented were as follows: June 30, 2017 Total Level 1 Level 2 Level 3 (In thousands) Assets: Derivative assets – diesel fuel contracts $ 38 $ — $ 38 $ — Derivative assets – interest rate swap 547 — 547 — Total assets at fair value on a recurring basis $ 585 $ — $ 585 $ — Liabilities: Derivative liability - diesel fuel contracts $ 277 $ — $ 277 $ — Derivative liability - interest rate swap 462 — 462 — Contingent consideration for acquisitions 858 — — 858 Total liabilities at fair value on a recurring basis $ 1,597 $ — $ 739 $ 858 March 31, 2017 Total Level 1 Level 2 Level 3 (In thousands) Assets: Derivative assets – diesel fuel contracts $ 179 $ — $ 179 $ — Total assets at fair value on a recurring basis $ 179 $ — $ 179 $ — Liabilities: Derivative liability - diesel fuel contracts $ 142 $ — $ 142 $ — Contingent consideration for acquisitions 1,348 — — 1,348 Total liabilities at fair value on a recurring basis $ 1,490 $ — $ 142 $ 1,348 For the three months ended June 30, 2017 and 2016, respectively, there were no transfers in or out of Levels 1, 2 or 3. Valuation of Contingent Consideration for Acquisitions - The fair values of the contingent consideration payables for acquisitions were calculated based on a discounted cash flow model, whereby the probability-weighted future payment value is discounted to the present value using a market discount rate. The method used to price these liabilities is considered Level 3, due to the subjective nature of the unobservable inputs used to determine the fair value. Changes in the fair value of recurring fair value measurements using significant unobservable inputs (Level 3) for the periods presented were as follows: Three Months ended June 30, 2017 2016 (In thousands) Balance at the beginning of the period $ 1,348 $ 2,858 Change in fair value 26 24 Payments of contingent consideration liability (516 ) (683 ) Balance at the end of the period $ 858 $ 2,199 Valuation of Debt - The carrying amounts of current financial assets and liabilities approximate fair value because of the immediate or short-term maturity of these items, or in the case of derivative instruments, because they are recorded at fair value. The carrying and fair value of the Company’s Senior Notes (discussed in “Note 6. Debt”) were $150.0 million and $150.3 million, respectively, as of June 30, 2017 and $75.0 million and $75.9 million, respectively, at March 31, 2017. The fair value of the Senior Notes was determined based on a comparison of the interest rate and terms of such borrowings to the rates and terms of similar debt available for the period. The Company believes the carrying amount on the remaining long-term debt, including the Secured Bank Term Loans, is not materially different from its fair value as the interest rates and terms of the borrowings are similar to currently available borrowings. The categorization of the framework used to evaluate this debt is considered Level 2.

During fiscal 2017, the Company issued $4.6 million of Equipment Notes with a weighted average fixed interest rate at 2.72%, with the aggregate loan amount during fiscal 2017 reaching a total of $4.2 million, net of principal payments. Each Equipment Note amortizes the principal over five years and is payable monthly. Events Related to the Secured Bank Term Loans - On May 19, 2017, the Company obtained a waiver from the lenders of the Revolving Credit Facility regarding an event of default. A material domestic subsidiary failed to join as a guarantor resulting in default. The lenders agreed to waive the default if the material domestic subsidiary joins as a guarantor by July 31, 2017. The material domestic subsidiary joined as a guarantor on June 22, 2017 upon the closing of the amended Secured Bank Term Loans discussed below. On June 28, 2017, ADS executed a Forward Interest Rate Swap on the 30-Day LIBOR interest rate to mitigate the impact of interest rate volatility. The swap has a notional value of $100.0 million and a fixed rate of 1.8195% for a five year period. Events Related to the Senior Notes - On June 28, 2017, the Company issued and sold Shelf Notes in the aggregate principal amount of $75.0 million pursuant to the Private Shelf Agreement. The $75.0 million of Shelf Notes bears interest at a fixed interest rate of 3.53% per annum and have a maturity date of seven years from the date of issuance. The rate is subject to an additional 100 basis point excess leverage fee if the calculated leverage ratio exceeds 3 to 1 at the end of a fiscal quarter. Long-term Debt Modification Secured Bank Term Loans - On June 22, 2017, the Company and certain of its subsidiaries, as guarantors (collectively, the “Guarantors”), entered into a Second Amended and Restated Credit Agreement (the “Credit Agreement”) with PNC Bank, National Association (“PNC”), as administrative agent (in such capacity, the “Agent”), and various financial institutions party thereto (together with PNC, collectively, the “Lenders”), pursuant to which the Lenders have committed to provide the Company a $550.0 million revolving credit facility (with an option to increase such revolving credit facility or incur new term loans in an agreement amount of up to $150.0 million) subject to the terms and conditions in the Credit Agreement. The Credit Agreement amends and restates the Amended and Restated Credit Agreement dated as of June 12, 2013, as amended, among the Company and certain of its subsidiaries, as guarantors, various financial institutions party thereto, and PNC, as administrative agent. Borrowings under the credit facility will be used for general corporate purposes, including repurchases of stock, repayments of existing indebtedness, repayments of short-term borrowings, working capital requirements, capital expenditures and acquisitions. The interest rates under the Credit Agreement are determined by certain base rates or LIBOR rates, plus an applicable margin based on the Leverage Ratio then in effect. The average interest rate was 2.87% as of June 30, 2017. The Credit Agreement has an expiration date of June 22, 2022. The Credit Agreement sets forth certain customary business and financial covenants to which the Company and Guarantors are subject when any amounts under the Credit Agreement are outstanding, including covenants that limit or restrict the ability of the Company and the Guarantors to incur indebtedness, to make capital distributions, and to incur certain liens and encumbrances on any of its respective property. The two primary financial covenants of the Credit Agreement require the Company to maintain a certain Leverage Ratio and an Interest Coverage Ratio. The Credit Agreement Leverage Ratio generally requires that at the end of any fiscal quarter, for the four fiscal quarters then ended, the Company will not permit the ratio of its total consolidated indebtedness to the Company’s Consolidated EBITDA (as defined in the Credit Agreement) to be greater than 4.00 to 1.00 (or 4.25 to 1.00 as of the date of any acquisitions permitted under the Credit Agreement for which the aggregate consideration is $100.0 million or greater). The Credit Agreement Interest Coverage Ratio generally requires that at the end of any fiscal quarter, for the four fiscal quarters then ended, the Company will not permit the ratio of Consolidated EBITDA to the Company’s consolidated interest expense payable during such period to be less than 3.00 to 1.00. The Credit Agreement provides for customary events of default, including, among other things, in the event of nonpayment of principal, interest, or other amounts, a representation or warranty proving to have been incorrect in any material respect when made, failure to perform or observe certain covenants within a specified period of time, a cross-default to other Company indebtedness of a specified amount, the bankruptcy or insolvency of the Company or a Guarantor, monetary judgment defaults of a specified amount, a change of control of the Company, and ERISA defaults resulting in liability under certain circumstances. In the event of a default by the Company, the Agent or the requisite number of Lenders may declare all amounts owed under the Credit Agreement and outstanding letters of credit immediately due and payable and terminate the Lenders’ commitments to make loans under the Credit Agreement. For defaults related to bankruptcy, insolvency or reorganization proceedings, the commitments of the Lenders will be automatically terminated and all outstanding loans and other amounts will become immediately due and payable. Senior Notes - On June 22, 2017, the Company and the Guarantors entered into the Second Amended and Restated Private Shelf Agreement (the “Private Shelf Agreement”) with PGIM, Inc. (“Prudential”) and certain other parties thereto. The Private Shelf Agreement amends and restates the Amended and Restated Private Shelf Agreement dated as of September 24, 2010, as amended, pursuant to which the Company has previously issued and sold secured senior notes of the Company. Under the terms of the Private Shelf Agreement, the Company may request that Prudential purchase, over the next three years, secured senior notes of the Company so long as the aggregate principal amount of notes outstanding at any time does not exceed $175.0 million (the “Shelf Notes”). The Shelf Notes shall bear interest at a fixed interest rate and have a maturity date not to exceed ten years from the date of issuance. Prudential and its affiliates are under no obligation to purchase any of the Shelf Notes. The interest rate and terms of payment of any series of Shelf Notes will be determined at the time of purchase. The proceeds of any series of Shelf Notes will be used as specified in the request for purchase with respect to such series, subject to compliance with the requirements in the Private Shelf Agreement, but are anticipated to be used for general corporate purposes, including refinancing of short-term borrowings and/or repayment of outstanding indebtedness under the Credit Agreement, which is described above, as well as financing of capital expenditures and acquisitions. Obligations under the Private Shelf Agreement are secured by capital stock of certain direct and indirect subsidiaries of the Company and the Guarantors and substantially all other tangible and intangible personal property owned by the Company and the Guarantors. Obligations under the Private Shelf Agreement are secured by the collateral on a pari passu basis with obligations under the Credit Agreement. The Private Shelf Agreement sets forth certain customary business and financial covenants to which the Company and Guarantors are subject when any Shelf Note is outstanding, including covenants that limit or restrict the ability of the Company and the Guarantors to incur indebtedness, to make capital distributions, and to incur certain liens and encumbrances on any of its respective property. The two primary financial covenants of the Private Shelf Agreement require the Company to maintain a certain Leverage Ratio and an Interest Coverage Ratio. The Private Self Agreement Leverage Ratio generally requires that at the end of any fiscal quarter, for the four fiscal quarters then ended, the Company will not permit the ratio of its total consolidated indebtedness to the Company’s Consolidated EBITDA (as defined in the Private Shelf Agreement) to be greater than 4.00 to 1.00 (or 4.25 to 1.00 as of the date of any acquisitions permitted under the Private Self Agreement for which the aggregate consideration is $100.0 million or greater). The Private Self Agreement Interest Coverage Ratio generally requires that at the end of any fiscal quarter, for the four fiscal quarters then ended, the Company will not permit the ratio of Consolidated EBITDA to the Company’s consolidated interest expense payable during such period to be less than 3.00 to 1.00. The Private Shelf Agreement provides for customary events of default, including, among other things, in the event of nonpayment of principal, interest, or other amounts, a representation or warranty proving to have been incorrect in any material respect when made, failure to perform or observe certain covenants within a specified period of time, a cross-default to other Company indebtedness of a specified amount, the bankruptcy or insolvency of the Company or a Guarantor, monetary judgment defaults of a specified amount, a change of control of the Company, and ERISA defaults resulting in liability under certain circumstances. In the event of a default by the Company, any or all holders of Shelf Notes may declare amounts owed under the Private Shelf Agreement immediately due and payable. For defaults related to bankruptcy, insolvency or reorganization proceedings, all amounts owed under the Agreement will become immediately due and payable, and Prudential may at its option terminate the Private Shelf Note Facility.

Commitments and Contingencies	8. COMMITMENTS AND CONTINGENCIES Purchase Commitments - The Company secures supplies of resin raw material by agreeing to purchase quantities during a future given period at a fixed price. These purchase contracts typically range from 1 to 12 months and occur in the ordinary course of business. Under such purchase contracts in place at June 30, 2017, the Company has agreed to purchase resin over the period July 2017 through December 2017 at a committed purchase cost of $12.1 million. Litigation and Other Proceedings – On July 29, 2015, a putative stockholder class action, Christopher Wyche, individually and on behalf of all others similarly situated v. Advanced Drainage Systems, Inc., et al. (Case No. 1:15-cv-05955-KPF), was commenced in the U.S. District Court for the Southern District of New York (the “District Court”), naming the Company, along with Joseph A. Chlapaty, the Company’s Chief Executive Officer, and Mark B. Sturgeon, the Company’s former Chief Financial Officer, as defendants and alleging violations of the federal securities laws. An amended complaint was filed on April 28, 2016. The amended complaint alleges that the Company made material misrepresentations and/or omissions of material fact in its public disclosures during the period from July 25, 2014 through March 29, 2016, in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder. On March 10, 2017, the District Court dismissed Plaintiff’s claims against all defendants in their entirety and with prejudice. Plaintiff has appealed the District Court’s order to the United States Court of Appeals for the Second Circuit, and the appeal is pending. On August 12, 2015, the SEC Division of Enforcement (“Enforcement Division”) informed the Company that it was conducting an informal inquiry with respect to the Company. As part of this inquiry, the Enforcement Division requested the voluntary production of certain documents generally related to the Company’s accounting practices. Subsequent to the initial voluntary production request, the Company received document subpoenas from the Enforcement Division pursuant to a formal order of investigation. The Company has from the outset cooperated with the Enforcement Division’s investigation and intends to continue to do so. While it is reasonably possible that this investigation ultimately could be resolved unfavorably to the Company, the Company is currently unable to estimate the range of possible losses, but they could be material. The Company is involved from time to time in various legal proceedings that arise in the ordinary course of business, including but not limited to commercial disputes, environmental matters, employee related claims, intellectual property disputes and litigation in connection with transactions including acquisitions and divestitures. The Company does not believe that such litigation, claims, and administrative proceedings will have a material adverse impact on the Company’s financial position or results of operations. The Company records a liability when a loss is considered probable, and the amount can be reasonably estimated.

Income Taxes	9. INCOME TAXES The Company’s effective tax rate will vary based on a variety of factors, including overall profitability, the geographical mix of income before taxes and related tax rates in jurisdictions where it operates and other onetime charges, as well as discrete events. For the three months ended June 30, 2017 and 2016, the Company utilized an effective tax rate of 34.8% and 42.1%, respectively, to calculate its provision for income taxes. These rates differ from the federal statutory rate of 35% primarily due to the favorable impact of a $1.0 million discrete income tax benefit related to release of tax reserves.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-Based Compensation	10. ADS has several programs for stock-based payments to employees and directors, including stock options and restricted stock. Equity-classified restricted stock awards are measured based on the grant-date estimated fair value of each award. Liability-classified stock options are re-measured at fair value at each reporting date until the date of settlement, and the pro-rata vested portion of the award is recognized as a liability. The Company determines the fair value of options based on the Black-Scholes option pricing model. The Company accounts for all restricted stock granted to directors as equity-classified awards. The Company recognized stock-based compensation expense in the following line items of the Condensed Consolidated Statements of Operations for the three months ended June 30, 2017 and 2016: Three Months Ended June 30, 2017 2016 (in thousands) Component of income before income taxes: Cost of goods sold $ 45 $ 100 Selling expenses 25 300 General and administrative expenses 1,620 8,620 Total stock-based compensation expense $ 1,690 $ 9,020 The following table summarizes stock-based compensation expense by award type for the three months ended June 30, 2017 and 2016: Three Months Ended June 30, 2017 2016 (in thousands) Stock-based compensation expense: Liability-classified Stock Options $ — $ 8,836 Equity-classified Stock Options 1,084 — Restricted Stock 368 184 Non-Employee Director 238 — Total stock-based compensation expense $ 1,690 $ 9,020 On April 1, 2017, the Company modified all outstanding awards to remove the provision that permitted employees to satisfy their personal tax liability with the net settlement of shares in excess of minimum tax withholding. Consistent with the ASU in Note 1, employees can now withhold shares with a fair value up to the maximum statutory rate. Accordingly, the Company modified the awards previously accounted for as liability-classified to equity-classified and reclassified the carrying amount of the awards of $13.7 million to Paid-in capital in the Condensed Consolidated Balance Sheet. All stock options have been accounted for as equity-classified awards for the periods subsequent to the modification. Prior to the modification, liability-classified awards were reclassified to additional paid in capital at fair value when stock options were exercised.

Background and Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Jun. 30, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation – The Company prepares its Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The Condensed Consolidated Balance Sheet as of March 31, 2017 was derived from audited financial statements included in the Annual Report on Form 10-K for the year ended March 31, 2017 (“Fiscal 2017 Form 10-K”). The accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments, of a normal recurring nature, necessary to present fairly its financial position as of June 30, 2017 and the results of operations and cash flows for the three months ended June 30, 2017 and 2016. The interim Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements, including the notes thereto, filed in the Company’s Fiscal 2017 Form 10-K.
Principles of Consolidation	Principles of Consolidation – The Condensed Consolidated Financial Statements include the Company, its wholly-owned subsidiaries, its majority-owned subsidiaries and variable interest entities (“VIEs”) of which the Company is the primary beneficiary. The Company uses the equity method of accounting for equity investments where it exercises significant influence but does not hold a controlling financial interest. Such investments are recorded in Other assets in the Condensed Consolidated Balance Sheets and the related equity earnings from these investments are included in Equity in net loss (income) of unconsolidated affiliates in the Condensed Consolidated Statements of Operations. All intercompany balances and transactions have been eliminated in consolidation.
Recent Accounting Guidance	Recent Accounting Guidance Recently Adopted Accounting Guidance Measurement of Inventory – In July 2015, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) which requires entities to measure most inventory at the lower of cost and net realizable value, simplifying current guidance under which an entity must measure inventory at the lower of cost or market. The determination of market value, under current guidance, is considered unnecessarily complex as there are several potential outcomes based on its definition as replacement cost, net realizable value, or net realizable value less an approximate normal profit margin. Whereas net realizable value, under the update, is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This update is effective for annual periods beginning on or after December 15, 2016, and interim periods within those years, with early adoption permitted. The Company adopted this standard effective April 1, 2017. The new standard did not have a material impact on the Condensed Consolidated Financial Statements. Stock-Based Compensation – In March 2016, the FASB issued an ASU which is intended to simplify certain aspects of the accounting for stock-based compensation. The Company adopted the standard on April 1, 2017. The adoption of the ASU did not have a material impact on the historical consolidated financial statements. This update contains changes to the accounting for excess tax benefits, whereby excess tax benefits will be recognized in the income statement rather than in additional paid-in capital on the balance sheet. This update is expected to result in increased volatility to income tax expense in future periods dependent upon the timing of employee exercises of stock options, the price of the Company's common stock and the vesting of restricted stock awards. In addition, excess tax benefits will now be classified as operating cash flows rather than financing cash flows in the Consolidated Statements of Cash Flows. The amendment also contains potential changes to the accounting for forfeitures, whereby entities can elect to either continue to apply the current requirement to estimate forfeitures when determining compensation expense, or to alternatively reverse the compensation expense of forfeited awards when they occur. The Company will account for forfeitures as they occur, which may result in expense volatility based on the timing of forfeitures. In addition, the update also modified the net-share settlement liability classification exception for statutory income tax withholdings, whereby the new guidance allows an employer with a statutory income tax withholding obligation to withhold shares with a fair value up to the maximum statutory tax rate in the employee’s applicable jurisdiction. The Company included this provision in awards issued in fiscal 2017 and modified previously issued awards on April 1, 2017. See “Note 10. Stock-Based Compensation” for further information on the modification. Definition of a Business – In January 2017, the FASB issued an ASU to clarify the definition of a business. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The amendments are intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments provide a more robust framework to use in determining when a set of assets and activities is a business. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company adopted this standard effective April 1, 2018. The new standard did not have a material impact on the Condensed Consolidated Financial Statements. Recent Accounting Guidance Not Yet Adopted Revenue Recognition – In May 2014, the FASB issued an ASU which amends the guidance for revenue recognition. This standard contains principles that will require an entity to recognize revenue to depict the transfer of goods and services to customers at an amount that an entity expects to be entitled to in exchange for goods or services. The standard sets forth a new revenue recognition model that requires identifying the contract, identifying the performance obligations and recognizing the revenue upon satisfaction of performance obligations. In August 2015, the FASB issued an ASU that deferred the effective date of the new revenue standard for public entities to periods beginning after December 15, 2017, with early adoption permitted but not earlier than the original effective date of periods beginning after December 15, 2016. There have also been various additional accounting standards updates issued by the FASB in 2016 that further amend this new revenue standard. The updated standard permits the use of either the retrospective or cumulative effect transition method. The Company expects to adopt this standard effective April 1, 2018. The Company has not yet selected a transition method and is currently evaluating the impact of this standard on the consolidated financial statements. Leases – In February 2016, the FASB issued an ASU which amends the guidance for leases. This standard contains principles that will require an entity to recognize most leases on the balance sheet by recording a right-of-use asset and a lease liability, unless the lease is a short-term lease that has an accounting lease term of twelve months or less. The standard also contains other changes to the current lease guidance that may result in changes to how entities determine which contractual arrangements qualify as a lease, the accounting for executory costs such as property taxes and insurance, as well as which lease origination costs will be capitalizable. The new standard also requires expanded quantitative and qualitative disclosures. This standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those years, and early adoption is permitted. The standard requires the use of the modified retrospective transition method, whereby the new guidance will be applied at the beginning of the earliest period presented in the financial statements of the period of adoption. The modified retrospective transition approach includes certain practical expedients that entities may elect to apply in transition. The Company expects to adopt this standard effective April 1, 2019. The Company has not yet determined whether to apply any of the available practical expedients. The Company has begun the process of reviewing contracts under the new standard to determine the impact the new standard will have on the consolidated financial statements. The Company is also in process of implementing a new software solution to improve the process of accounting for leases under the current and new standard. Measurement of Credit Losses – In June 2016, the FASB issued an ASU which provides amended guidance on the measurement of credit losses on financial instruments, including trade receivables. This standard requires the use of an impairment model referred to as the current expected credit loss model. This standard is effective for fiscal years beginning after December 15, 2019, including interim periods within those years, and early adoption is permitted for fiscal years beginning after December 15, 2018. The Company expects to adopt this standard effective April 1, 2020. The Company is currently evaluating the impact of this standard on the consolidated financial statements. Cash Flow Classification – In August 2016, the FASB issued an ASU which provides amended guidance on the classification of certain cash receipts and cash payments in the statement of cash flows, including related to debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance and distributions received from equity method investees. This update is effective for fiscal years beginning after December 15, 2017, including interim periods within those years, and early adoption is permitted. This amended guidance must be applied retrospectively to all periods presented, but may be applied prospectively if retrospective application would be impracticable. The Company expects to adopt this update effective April 1, 2018. The Company is currently evaluating the impact of this update on the consolidated financial statements. Goodwill Impairment – In January 2017, the FASB issued an ASU which removes the requirement to compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. As a result, under the standards update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments are effect for annual periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company expects to adopt this standard effective April 1, 2020. The Company is currently evaluating the impact of this standard on the consolidated financial statements. Stock-Based Compensation – In May 2017, the FASB issued an ASU to clarify when modification accounting should be applied for changes to the terms or conditions of share-based payment awards. The amendments clarify that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company expects to adopt this standard effective April 1, 2018. The Company is currently evaluating the impact of this update on its consolidated financial statements. With the exception of the pronouncements described above, there have been no new accounting pronouncements issued or adopted since the filing of the Fiscal 2017 Form 10-K that have significance, or potential significance, to the Condensed Consolidated Financial Statements.
