Accounting Policies [Abstract]
Background and Summary of Significant Accounting Policies	1. BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization Advanced Drainage Systems, Inc. (collectively with its subsidiaries referred to as “ADS”, the “Company”, “we”, “us” and “our”), 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. Our 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. The reportable segments are Domestic and International. 2014 Initial Public Offering (“IPO”) On July 11, 2014, in anticipation of the IPO, we executed a 4.707-for-one split of our common and our preferred stock. The effect of the stock split on outstanding shares and earnings per share has been retroactively applied to all periods presented. On July 25, 2014, we completed the IPO of our common stock, which resulted in the sale by the Company of 5,289 shares of common stock. We received total proceeds from the IPO of $79,131 after excluding underwriter discounts and commissions of $5,501, based upon the price to the public of $16.00 per share. After deducting other offering expenses, we used the net proceeds to reduce the outstanding indebtedness under the revolving portion of our credit facility. The common stock is listed on the New York Stock Exchange under the symbol “WMS.” On August 22, 2014, an additional 600 shares of common stock were sold by certain selling stockholders of the Company as a result of the partial exercise by the underwriters of the over-allotment option granted by the selling stockholders to the underwriters in connection with the IPO. The shares were sold at the public offering price of $16.00 per share. The Company did not receive any proceeds from the sale of such additional shares. 2014 Secondary Public Offering On December 9, 2014, we completed a Secondary Public Offering of our common stock, which resulted in the sale of 10,000 shares of common stock by a certain selling stockholder of the Company at a public offering price of $21.25. We did not receive any proceeds from the sale of shares by the selling stockholder. On December 15, 2014, an additional 1,500 shares of common stock were sold by a certain selling stockholder of the Company as a result of the full exercise by the underwriters of the over-allotment option granted by the selling stockholder to the underwriters in connection with the Secondary Public Offering. The shares were sold at the public offering price of $21.25 per share. The Company did not receive any proceeds from the sale of such additional shares. Basis of Presentation The Company prepares its condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Condensed Consolidated Balance Sheet as of March 31, 2014 was derived from audited financial statements. In our opinion, the accompanying unaudited condensed consolidated financial statements contain all adjustments, of a normal recurring nature, in addition to the restatement adjustments described in Note 2. Restatement of Previously Issued Financial Statements, necessary to present fairly its financial position as of December 31, 2014 and the results of operations for the three and nine months ended December 31, 2014 and 2013 and cash flows for the nine months ended December 31, 2014 and 2013. The interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, filed in our Annual Report on Form 10-K for the year ended March 31, 2015, filed concurrently with this Form 10-Q/A. Principles of Consolidation Our condensed consolidated financial statements include the Company, our wholly-owned subsidiaries, our majority-owned subsidiaries, including ADS Mexicana, S.A. de C.V. (together with its affiliate ADS Corporativo, S.A. de C.V., “ADS Mexicana”), and variable interest entities (“VIEs”) of which we are the primary beneficiary. We use the equity method of accounting for equity investments where we exercise significant influence but do not hold a controlling financial interest. Such investments are recorded in Other assets in our Condensed Consolidated Balance Sheets and the related equity earnings from these investments is included in Equity in net loss of unconsolidated affiliates in our Condensed Consolidated Statements of Income. All intercompany balances and transactions have been eliminated in consolidation. Estimates The preparation of our condensed consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingencies and liabilities at the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Significant estimates include, but are not limited to, our allowance for doubtful accounts, inventory, useful lives of our property, plant and equipment and amortizing intangible assets, determination of the proper accounting for leases, accounting for investments, evaluation of goodwill, intangible assets and other long-lived assets for impairment, accounting for stock-based compensation and our ESOP, valuation of our Redeemable common stock and Redeemable convertible preferred stock, determination of allowances for sales returns, rebates and discounts, determination of the valuation allowance, if any, on deferred tax assets, and reserves for uncertain tax positions. Management’s estimates and assumptions are evaluated on an ongoing basis and are based on historical experience, current conditions and available information. Management believes the accounting estimates are appropriate and reasonably determined; however, due to the inherent uncertainties in making these estimates, actual results could differ from those estimates. Property, Plant and Equipment and Depreciation Method Property, plant and equipment are recorded at cost less accumulated depreciation, with the exception of assets acquired through acquisitions, which are initially recorded at fair value. Equipment acquired under capital lease is recorded at the lower of fair market value or the present value of the future minimum lease payments. Depreciation is computed for financial reporting purposes using the straight-line method over the estimated useful lives of the related assets or the lease term, if shorter, as follows: Years Buildings 40 Machinery and equipment 3 – 15 Leasehold improvements Shorter of useful Costs of additions and major improvements are capitalized, whereas maintenance and repairs that do not improve or extend the life of the asset are charged to expense as incurred. When assets are retired or disposed, the cost and related accumulated depreciation are removed from the asset accounts and any resulting gain or loss is reflected in Loss (gain) on disposal of assets or businesses in our Condensed Consolidated Statements of Operations. Construction in progress is also recorded at cost and includes capitalized interest, capitalized payroll costs and related costs such as taxes and other fringe benefits. Interest capitalized was $0 and $316 during the three and nine months ended December 31, 2014, respectively, and $80 and $490 during the three and nine months ended December 31, 2013, respectively. Leases Leases are reviewed for capital or operating classification at their inception. The Company uses the lower of the rate implicit in the lease or its incremental borrowing rate in the assessment of lease classification and assumes the initial lease term includes cancellable and renewal periods that are reasonably assured. For leases classified as capital leases at lease inception, we record a capital lease asset and lease financing obligation equal to the lesser of the present value of the minimum lease payments or the fair market value of the leased asset. The capital lease asset is recorded in Property, plant and equipment, net and amortized to its expected residual value at the end of the lease term using the straight-line method, and the lease financing obligation is amortized using the interest method over the lease term with the rental payments being allocated to principal and interest. For leases classified as operating leases, we record rent expense over the lease term using the straight-line method. Acquisitions In accordance with ASC Topic 805, “Business Combinations” Recent Accounting Pronouncements Not Yet Adopted In April 2014, the Financial Accounting Standards Board issued authoritative guidance amending existing requirements for reporting discontinued operations. Under the new guidance, discontinued operations reporting will be limited to disposal transactions that represent strategic shifts having a major effect on operations and financial results. The amended guidance also enhances disclosures and requires assets and liabilities of a discontinued operation to be classified as such for all periods presented in the financial statements. Public entities will apply the amended guidance prospectively to all disposals occurring within annual periods beginning on or after December 15, 2014, and interim periods within those years. We will adopt this standard effective April 1, 2015. We are currently evaluating the impact of this amendment on our consolidated financial statements. In May 2014, the Financial Accounting Standards Board issued an accounting standards update which amends the guidance for revenue recognition. This amendment 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 amendment 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. This amendment is effective for annual periods beginning on or after December 15, 2016, and interim periods within those years, with earlier adoption not permitted. We will adopt this standard effective April 1, 2017. We are currently evaluating the impact of this amendment on our consolidated financial statements. In August 2014, the Financial Accounting Standards Board issued an accounting standards update which provides guidance for management’s assessment of an entity’s ability to continue as a going concern. The new guidance is intended to define management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The guidance provides a definition of the term substantial doubt and requires an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). It also requires certain disclosures when substantial doubt is alleviated as a result of the consideration of management’s plans and requires an express statement and other disclosures when substantial doubt is not alleviated. The new standard will be effective for annual periods beginning on or after December 15, 2016, and interim periods within those years, with earlier adoption permitted. We will adopt this standard effective April 1, 2017. We are currently evaluating the impact of this new standard on our consolidated financial statements.

Accounting Changes and Error Corrections [Abstract]
Restatement of Previously Issued Financial Statements	2. RESTATEMENT OF PREVIOUSLY ISSUED FINANCIAL STATEMENTS Background In June of 2015, in connection with the preparation of the Company’s consolidated annual financial statements for the fiscal year ended March 31, 2015, certain errors related to the Company’s accounting treatment for its transportation and equipment leases and inventory methodology were identified. As the Company completed additional accounting review procedures, it identified additional errors related to long-lived assets, ADS Mexicana, and certain other miscellaneous items. Due to these errors, as further described below, and based upon the recommendation of management, the Audit Committee of the Company’s Board of Directors (the “Audit Committee”) determined on August 14, 2015 that the Company’s previously issued financial statements should no longer be relied upon. As a result of the foregoing the Company has restated its condensed consolidated financial statements as of December 31, 2014 and March 31, 2014 and for the three and nine months ended December 31 2014 and 2013. The restatement also affects periods prior to fiscal year 2014, with the cumulative effect of the errors reflected as an adjustment to the fiscal year 2014 opening stockholders’ equity (deficit) balance. Accounting Adjustments The following is a discussion of the significant accounting adjustments that were made to the Company’s historical condensed consolidated financial statements. Lease Accounting Adjustments The Company leases real estate and equipment under various lease agreements. Historically, assets leased under the Company’s transportation and equipment leasing program (“Fleet Leases”) have been classified as operating leases. However, based upon a reexamination of the Company’s historic assumptions, estimates and judgments with respect to lease accounting, the Company has determined that a substantial portion of the Fleet Leases should instead be classified as capital leases. The Company has also reexamined its historic assumptions, estimates and judgments with respect to the accounting for real estate and aircraft leases that were previously classified as operating leases. In many cases, the Company has determined that the leases should instead be classified as capital leases due to the inclusion of contingent penalty amounts in the minimum lease payments used for purposes of the lease classification assessment. Inventory Accounting Adjustments The Company identified and corrected certain errors related to its accounting for inventory. The errors primarily related to the Company’s incorrect historical calculation of inventory costing based on the first-in, first-out (“FIFO”) method, the inappropriate capitalization of certain inter-plant freight expense and other overhead costs, the misclassification of certain overhead costs between general and administrative expense and cost of goods sold and the misclassification of our financial fuel hedge losses between Cost of goods sold and Other miscellaneous expense (income), net. Long-Lived Assets Accounting Adjustments The Company identified and corrected certain errors related to the accounting for long-lived assets included in Property, plant and equipment, Goodwill, Intangible assets and Other assets in the condensed consolidated balance sheets. These errors primarily related to either the initial capitalization, subsequent depreciation or amortization, or the timing or amount of impairment charges. ADS Mexicana Accounting Adjustments In October 2015, the Company became aware of questions related to the proper characterization of certain ADS Mexicana transactions including an aircraft leasing arrangement, a real estate leasing arrangement and several service arrangements that involved ADS Mexicana related parties. Based on the results of a management review and an independent investigation authorized by the Audit Committee, it was determined that the various lease and services arrangements described above, as well as certain additional services arrangements with former related parties identified during the course of the investigation, lacked commercial and economic substance or proper supporting documentation as to the service performed, and therefore were not appropriately reflected in the Company’s consolidated financial statements. These errors have been corrected in the restated condensed consolidated financial statements, with these adjustments primarily impacting Other miscellaneous expense (income), net, Net income attributable to noncontrolling interest and Noncontrolling interest in subsidiaries. Management also identified potential accounting errors related to ADS Mexicana’s revenue recognition cut-off practices, which were included in the scope of the independent investigation authorized by the Audit Committee. As a result, the Company identified instances where ADS Mexicana recognized revenue prior to the date of shipment or transfer of title/ownership, which is not in accordance with US GAAP. The Company also identified and corrected certain other errors related to the accounting for ADS Mexicana. These adjustments related to the increase of the allowance for doubtful accounts, errors related to the inventory costing methodology, and certain other miscellaneous items. Income Taxes and Other Accounting Adjustments The Company recorded adjustments to income taxes to reflect the impact of the restatement adjustments, as well as discrete tax adjustments related to transfer pricing. See Note 18. Income Taxes for discussion of the related impact to our effective tax rate. The Company also identified and corrected certain other errors, all of which are insignificant individually and in the aggregate. The nature of the primary items besides income taxes in this category of adjustments is described as follows: • The adjustments to the accrued liability for customer rebates are the result of the Company’s prior methodology not properly capturing all rebates due at period end. • The adjustments related to the Tuberias Tigre – ADS Limitada joint venture (“South American Joint Venture”) were the result of an impairment of equipment in the fiscal year ended March 31, 2014 that was not identified until the time of a subsequent-year statutory audit. As a result, the Company has corrected its equity method accounting to properly reflect the impairment charge. Impact on Condensed Consolidated Statements of Operations The net effect of the restatement described above on the Company’s previously reported condensed consolidated statements of operations for the three months ended December 31, 2014 and 2013 is as follows: Three Months Ended December 31, 2014 Adjustments (Amounts in thousands, except per share data) As Previously Leases Inventory Long-Lived

Leased assets accounted for as capital leases and included in Property, plant and equipment consisted of the following: December 31, 2014 March 31, 2014 (Amounts in thousands) Buildings and improvements $ 7,163 $ 7,716 Machinery and equipment 167,512 145,980 Total cost 174,675 153,696 Accumulated amortization (99,052 ) (89,599 ) Leased assets in Property, plant and equipment, net $ 75,623 $ 64,097 The following is a schedule by year of future minimum lease payments under capital leases together with the present value of the net minimum lease payments as of December 31, 2014: Future minimum lease payments - Capital leases (Amounts in thousands) December 31, 2015 $ 17,485 December 31, 2016 15,448 December 31, 2017 12,556 December 31, 2018 9,661 December 31, 2019 7,129 Thereafter 8,467 Total minimum lease payments (a) $ 70,746 Less: amount representing interest (b) 8,238 Present value of net minimum lease payments $ 62,508 Lease Obligation – Current 14,677 Lease Obligation – Long-term 47,831 Total lease obligation $ 62,508 (a) Excludes contingent rentals which may be paid. Contingent rentals amounted to $599 and $65 for the nine months ended December 31, 2014 and 2013, respectively. (b) Amount necessary to reduce minimum lease payments to present value calculated at the lower of the rate implicit in the lease or the Company’s incremental borrowing rate at lease inception. During the three months ended December 31, 2014 and 2013, the Company acquired equipment under capital lease and incurred lease obligations of $2,373 and $1,690, respectively and during the nine months ended December 31, 2014 and 2013, the Company acquired equipment under capital lease and incurred lease obligations of $22,531 and $18,063, respectively. Certain leases contain residual value guarantees that create a contingent obligation on the part of the Company to compensate the lessor if the leased asset cannot be sold for an amount in excess of a specified minimum value at the conclusion of the lease term. The calculation is based on the original cost of the transportation equipment, less lease payments made, compared to a percentage of the transportation equipment’s fair market value at the time of sale. All leased units covered by this guarantee have been classified as capital leases and a corresponding capital lease obligation was recorded. Therefore, no further contingent obligation is needed. Operating leases We lease certain real estate and office equipment under various cancelable and non-cancelable operating lease agreements that expire at various dates through fiscal year 2037. Total rent expense was $899 and $941 for the three months ended December 31, 2014 and 2013, respectively, and $2,524 and $3,172 for the nine months ended December 31, 2014 and 2013, respectively. Future minimum rental commitments under operating leases as of December 31, 2014, are summarized below (amounts in thousands): Twelve Months Ended December 31, 2015 2016 2017 2018 2019 Thereafter Future operating lease payments $ 2,915 $ 2,162 $ 1,159 $ 659 $ 442 $ 2,281

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	8. FAIR VALUE MEASUREMENT The fair value measurements and disclosure principles of ASC 820 - Fair Value Measurements and Disclosures define fair value, establish a framework for measuring fair value and provide disclosure requirements about fair value measurements. These principles define a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity has the ability to access as of the measurement date. Level 2 — Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 — Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. When applying fair value principles in the valuation of assets and liabilities, we are 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 periods presented. Our fair value estimates take into consideration the credit risk of both the Company and our counterparties. When active market quotes are not available for financial assets and liabilities, we use 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 our 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 December 31, 2014 and March 31, 2014 were as follows: December 31, 2014 (Amounts in thousands) Total Level 1 Level 2 Level 3 Assets: Derivative assets - currency forward contracts $ 256 $ — $ 256 $ — Total assets at fair value on a recurring basis $ 256 $ — $ 256 $ — Liabilities: Derivative liability - interest rate swaps $ 651 $ — $ 651 $ — Derivative liability - diesel fuel contracts 3,076 — 3,076 — Derivative liability - propylene swaps 2,060 — 2,060 — Derivative liability - currency forward contracts 1,660 — 1,660 — Contingent consideration for acquisitions 2,365 — — 2,365 Total liabilities at fair value on a recurring basis $ 9,812 $ — $ 7,447 $ 2,365 March 31, 2014 (Amounts in thousands) Total Level 1 Level 2 Level 3 Assets: Derivative assets - propylene swaps $ 27 $ — $ 27 $ — Total assets at fair value on a recurring basis $ 27 $ — $ 27 $ — Liabilities & Mezzanine Equity: Derivative liability - interest rate swaps $ 1,001 $ — $ 1,001 $ — Contingent consideration for acquisitions 2,898 — — 2,898 Redeemable common stock 549,119 — — 549,119 Redeemable convertible preferred stock 291,720 — — 291,720 Deferred compensation - unearned ESOP shares (197,888 ) — — (197,888 ) Total liabilities & mezzanine equity at fair value on a recurring basis $ 646,850 $ — $ 1,001 $ 645,849 Changes in the fair value of recurring fair value measurements using significant unobservable inputs (Level 3) for the three and nine months ended December 31, 2014 and 2013 were as follows: Three Months Ended (amounts in thousands) Contingent consideration Total Balance at September 30, 2014 $ 2,526 $ 2,526 Allocation of ESOP shares to participants — — Change in fair value (7 ) (7 ) Payments of contingent consideration liability (154 ) (154 ) Transfer from Level 3 — — Balance at December 31, 2014 $ 2,365 $ 2,365 Three Months Ended December 31, 2013 Redeemable Deferred convertible compensation (amounts in thousands) Contingent consideration Redeemable common stock preferred unearned Total Balance at September 30, 2013 $ 2,467 $ 553,189 $ 295,574 $ (201,837 ) $ 649,393 Allocation of ESOP shares to participants — — — 3,433 3,433 Change in fair value (37 ) 24,831 12,750 (9,022 ) 28,522 Payments of contingent consideration liability (104 ) — — — (104 ) Redemption of Redeemable convertible preferred stock — — (743 ) — (743 ) Balance at December 31, 2013 $ 2,326 $ 578,020 $ 307,581 $ (207,426 ) $ 680,501 Nine Months Ended December 31, 2014 Redeemable Deferred convertible compensation (amounts in thousands) Contingent consideration Redeemable common stock preferred unearned Total Balance at March 31, 2014 $ 2,898 $ 549,119 $ 291,720 $ (197,888 ) $ 645,849 Allocation of ESOP shares to participants — — — 4,391 4,391 Change in fair value (5 ) 65,921 34,903 (23,849 ) 76,970 Payments of contingent consideration liability (528 ) — — — (528 ) Transfer from Level 3 — (615,040 ) (326,623 ) 217,346 (724,317 ) Balance at December 31, 2014 $ 2,365 $ — $ — $ — $ 2,365 Nine Months Ended December 31, 2013 Redeemable Deferred convertible compensation (amounts in thousands) Contingent consideration Redeemable common stock preferred unearned Total Balance at March 31, 2013 $ 2,679 $ 522,276 $ 282,547 $ (196,477 ) $ 611,025 Allocation of ESOP shares to participants — — — 9,482 9,482 Change in fair value 92 55,359 28,923 (20,431 ) 63,943 Payments of contingent consideration liability (445 ) — — — (445 ) Redemption of Redeemable convertible preferred stock — — (3,889 ) — (3,889 ) Transfer to Level 3 — 385 — — 385 Balance at December 31, 2013 $ 2,326 $ 578,020 $ 307,581 $ (207,426 ) $ 680,501 For the nine months ended December 31, 2014 our Redeemable common stock transferred out of Level 3, as these securities started actively trading on the NYSE during the second quarter of fiscal 2015. In addition, our Redeemable convertible preferred stock and Deferred compensation – unearned ESOP shares were reclassified from a recurring Level 3 fair value measurement to a non-recurring Level 3 fair value measurement as a result of the IPO. See Note 1 for further information on the IPO. There were no further transfers in or out of Levels 1, 2 and 3 for the nine months ended December 31, 2014 and 2013, respectively. Valuation of our Contingent Consideration for Acquisitions The fair values of the contingent consideration payables were calculated with reference to the estimated future value of the Inserta Tee and Flexstorm businesses, which are based on a discounted cash flow model. The undiscounted value is discounted at the present value using a market discount rate. The categorization of the framework used to price this liability is considered a Level 3, due to the subjective nature of the unobservable inputs used to determine the fair value. Valuation of our Redeemable Common Stock The Company has certain shares of common stock outstanding allowing the holder to put its shares to us for cash. This Redeemable common stock was historically recorded at its fair value in the mezzanine equity section of our Condensed Consolidated Balance Sheets and changes in fair value were recorded in Retained earnings. Historically, the fair value of a share of common stock was determined by management by applying industry-appropriate multiples to EBITDA and performing a discounted cash flow analysis. Under the industry-appropriate multiples approach, to arrive at concluded multiples, we considered differences between the risk and return characteristics of ADS and the guideline companies. Under the discounted cash flow analysis, the cash flows expected to be generated by the Company are discounted to their present value equivalent using a rate of return that reflects the relative risk of an investment in ADS, as well as the time value of money. This return is an overall rate based upon the individual rates of return for invested capital (equity and interest-bearing debt). The return, known as the weighted average cost of capital (“WACC”), is calculated by weighting the required returns on interest-bearing debt and common stock in proportion to their estimated percentages in an expected capital structure. The WACC used was 11% as of March 31, 2014. An increase in the WACC would decrease the fair value of the Redeemable common stock. The categorization of the framework used to price this temporary equity is considered a Level 3, due to the subjective nature of the unobservable inputs used to determine the fair value. The redemption feature of our Redeemable common stock allowing the holder to put its shares to us for cash, as discussed in the previous paragraph, was not in effect upon effectiveness of the IPO on July 25, 2014. As a result, the Redeemable common stock was recorded as mezzanine equity at fair value through the effective date of the IPO and was subsequently reclassified at that fair value to stockholders’ equity. See Note 1. Background and Summary of Significant Accounting Policies for more information on the IPO. Nonrecurring Fair Value Measurements Valuation of our Redeemable Convertible Preferred Stock The Trustee of the Company’s ESOP has the ability to put the shares of our Redeemable convertible preferred stock to the Company. Our Redeemable convertible preferred stock is recorded at its fair value in the mezzanine equity section of our Condensed Consolidated Balance Sheets and changes in fair value are recorded in Retained earnings. Accordingly, we estimated the fair value of the Redeemable Convertible Preferred Stock through estimating the fair value of the Company’s common stock and applying certain adjustments including for the fair value of the total dividends to be received and assuming conversion of the Redeemable convertible preferred stock to common stock at the stated conversion ratio per our Certificate of Incorporation. The categorization of the framework used to price this temporary equity is considered a Level 3, due to the subjective nature of the unobservable inputs used to determine the fair value. Upon the effective date of the IPO, the redemption feature of our Redeemable convertible preferred stock allowing the Trustee of the Company’s ESOP to put shares to us for cash was no longer applicable. However, if our common stock, which our Redeemable convertible preferred stock may convert to, is no longer a “registration-type class of security” (e.g., in the event of a delisting), the option held by the Trustee, which granted it the ability to put the shares of our Redeemable convertible preferred stock to us, would then become applicable. Preferred securities that become redeemable upon a contingent event that is not solely within the control of the Company should be classified outside of permanent equity. As of December 31, 2014, the Company has determined that it is not probable that the redemption feature will become applicable. Since the Redeemable convertible preferred stock is not currently redeemable and it is not probable that the instrument will become redeemable, subsequent adjustment to fair value is not required.

The Revolving Credit Facilities expire and the Term note is due in June 2018. The Revolving Credit Facilities and the Term note have a variable interest rate that depends upon the Company’s “pricing ratio” as defined in the agreements for the Revolving Credit Facilities. The interest rate is derived from the London InterBank Offered Rate (“LIBOR”) or alternate base rate (“Prime Rate”) at the Company’s option. The average rate at December 31, 2014 was 3.01%. Any letters of credit outstanding reduce the availability on the revolver. The Company had outstanding letters of credit at December 31, 2014 in the amount of $8,005. The amount available for borrowing for ADS was $178,195, plus $12,000 available under a separate revolving credit facility with our subsidiary, ADS Mexicana, at December 31, 2014. Per the terms of the agreements for the Revolving Credit Facilities, ADS is not required to hedge its interest exposure using interest rate swaps; however, it is currently the objective of ADS to manage its exposure to variable rate debt. On July 18, 2013, ADS executed two Forward Interest Rate Swaps on the 30-Day LIBOR interest rate. One swap was for $50,000 and has a fixed rate of 0.86% for a period of three years beginning on September 3, 2013 and expiring on September 1, 2016. The second swap executed on July 18, 2013 was for $50,000 and has a fixed rate of 1.08% for a period of two years beginning on September 2, 2014 and expiring on September 1, 2016. Senior Notes Payable In December 2009, we signed an agreement with Prudential Investment Management, Inc. for the issuance of senior promissory notes (“Senior Notes”), for an aggregate amount of up to $100,000. During fiscal 2010, we issued $75,000 of Senior Notes with interest fixed at 5.6% and payable quarterly. The rate is subject to an additional 200 basis point excess leverage fee if our calculated leverage ratio exceeds 3 to 1 at the end of a fiscal quarter. A principal payment of $25,000 is due in each of fiscal years 2017, 2018, and 2019. In July 2013, ADS issued an additional $25,000 of Senior Notes. Interest for the additional $25,000 is payable quarterly and is fixed at 4.05%. The rate is subject to an additional 200 basis point excess leverage fee if calculated leverage ratio exceeds 3 to 1 at the end of a fiscal quarter. A principal payment of $25,000 is due in September of the fiscal year 2020. The carrying and fair values of the Company’s Senior Notes were $100,000 and $103,303, respectively, as of December 31, 2014 and $100,000 and $104,511, respectively, at March 31, 2014. The fair value of the Senior Notes was determined based on the interest rate and terms of such borrowings to the rates and terms of similar debt available for the period. The categorization of the framework used to evaluate this debt is considered Level 2. See Note 8. Fair Value Measurement to these financial statements. Mortgage Notes Payable One mortgage note payable with a fixed rate of 5.1% (Hilliard, Ohio) requires monthly installments through fiscal year 2015. Land and building with a net book value of approximately $4,914 at December 31, 2014 collateralize the mortgage note. In September 2014, a second mortgage with a variable interest rate was paid off (New Miami, Ohio). Industrial Revenue Bonds Between 1996 and 2007, ADS issued industrial revenue bonds for the construction of four production facilities. Two of the bonds were retired during fiscal 2011 year and one of the bonds was retired in July of fiscal year 2015. The remaining bond has a variable interest rate based on Securities Industry and Financial Markets Association (SIFMA) municipal swap index rate which is computed weekly. The rate on this bond at December 31, 2014 was 3.84%, including a letter of credit fee of 3.75%. Land and buildings with a net book value of approximately $10,047 at December 31, 2014 collateralize the bond. The bond is not considered an auction rate security. Debt Covenants The Bank Term Loans and the Senior Notes require, among other provisions, that we (1) maintain a 1.25 to 1 minimum fixed charge coverage ratio; (2) maintain a maximum leverage ratio of 4 to 1; and (3) establish certain limits on permitted transactions, principally related to indebtedness, capital distributions, loans and investments, and acquisitions and dispositions of assets. Capital distributions, including dividends, are prohibited if we are not in compliance with our debt covenants. In any fiscal year, if we are in compliance with all debt covenants and the pro-forma leverage ratio exceeds 3 to 1, capital distributions are permitted up to a limit of $50,000.

Equity [Abstract]
Redeemable Convertible Preferred Stock	16. REDEEMABLE CONVERTIBLE PREFERRED STOCK The Trustee of the Company’s ESOP has the ability to put shares of our redeemable convertible preferred stock to the Company. The redeemable convertible preferred stock has a required cumulative 2.5% dividend (based on the issue price of $0.781 per share) and is convertible at a rate of 0.7692 shares of common stock for each share of Redeemable convertible preferred stock. We guarantee the value of the redeemable convertible preferred stock at $0.781 per share. The put option requirements of the Internal Revenue Code apply in the event that the Company’s common stock is not a registration type class of security or its trading has been restricted. Therefore, the holders of convertible preferred stock have a put right to require us to repurchase such shares in the event that our common stock is not listed for trading or otherwise quoted on the NYSE, AMEX, NASDAQ, or any other market more senior than the OTC Bulletin Board. Given that the event may trigger redemption of the convertible preferred stock (the listing or quotation on a market more senior than the OTCBB) is not solely within our control, our Redeemable convertible preferred stock is presented in the mezzanine section of our Condensed Consolidated Balance Sheets as of December 31, 2014. In accordance with ASC 480-10-S99, as of December 31, 2014, we did not adjust the carrying value of the convertible preferred stock to its redemption value or recognize any changes in fair value as we did not consider it probable that the convertible preferred stock would become redeemable.

Stock-Based Compensation	17. STOCK-BASED COMPENSATION Deferred Compensation — Unearned ESOP Shares The fair value of Redeemable convertible preferred stock held by the ESOP trust, but not yet earned by the ESOP participants or used for dividends, is reported as Deferred compensation — Unearned ESOP shares within the mezzanine equity section of our Condensed Consolidated Balance Sheets. Compensation expense and related dividends paid with ESOP shares are recognized based upon the average annual fair value of the shares allocated. The shares allocated are for services rendered throughout the period and, therefore, a simple average is used to calculate average annual fair value. Deferred compensation – Unearned ESOP shares are relieved at the fair value, with any difference between the average fair value and the fair value shares when allocated being added to Additional paid in capital. The fair value of the shares allocated was $12.50 and $11.75 per share of Redeemable convertible preferred stock at December 31, 2014 and 2013, respectively, resulting in an average fair value per share of $12.34 and $11.20 for the nine months ended December 31, 2014 and 2013, respectively. We recognized compensation expense of $2,690 and $2,317 for the three months ended December 31, 2014 and 2013, respectively, and $8,064 and $7,343 for the nine months ended December 31, 2014 and 2013, respectively, related to allocation of ESOP shares to participants for compensation. Stock Options Our 2000 stock option plan (“2000 Plan”) provides for the issuance of incentive common stock options and nonstatutory common stock options to management based upon the discretion of the Board of Directors. The plan generally provides for grants with the exercise price equal to fair value on the date of grant, which vest in three equal annual amounts beginning in year five and expire after 10 years from issuance. In August 2013, a new stock option plan (“2013 Plan”) was approved by the Board of Directors and, as amended, provides for the issuance of up to 3,323 nonstatutory common stock options to management subject to the Board’s discretion. The plan generally provides for grants with the exercise price equal to fair value on the date of grant. The grants vest in five equal annual amounts beginning in year one and expire after 10 years from issuance. Options issued to the Chief Executive Officer vest equally over four years and expire after 10 years from issuance. In May 2014, the Board of Directors approved the increase of shares available for granting under the 2013 plan to 1,412 shares. For both stock option plans, management determines the fair value of the options based on the Black-Scholes option pricing model. This methodology requires significant inputs including the fair value of our common stock, which is determined with the assistance of an independent appraisal performed by a reputable valuation firm. We recognized total stock-based compensation expense under both plans of $1,178 and $945 for the three months ended December 31, 2014 and 2013, respectively, and $3,557 and $1,407 for the nine months ended December 31, 2014 and 2013, respectively, which was included with General and administrative expenses in our Condensed Consolidated Statements of Operations. As of December 31, 2014 and 2013, there was a total of $4,133 and $8,103, respectively, of unrecognized compensation expense related to unvested stock option awards that will be recognized as an expense as the awards vest over the remaining service period. We had approximately 1,097 and 1,412 shares available for granting under the 2000 and 2013 plans, respectively, as of December 31, 2014. We estimate the fair value of stock options granted after April 1, 2006, using a Black-Scholes option-pricing model, with assumptions as follows: December 31, 2014 2013 Expected stock price volatility 40 % 44 % Risk-free interest rate 2.1 % 2.3 % Weighted-average expected option life (years) 8 8 Dividend yield 0.86 % 0.84 % 2000 Plan The stock option transactions as of the nine months ended December 31 are summarized as follows: December 31, 2014 December 31, 2013 Number Weighted Weighted Number Weighted Weighted Outstanding at beginning of period 913 $ 9.48 4.1 1,333 $ 8.10 4 Issued 78 15.74 — 14 13.64 — Exercised 87 7.56 — 141 6.82 — Forfeited 3 15.74 — 5 10.77 — Outstanding at end of period 901 10.18 4 1,201 8.30 3.5 Exercisable and vested at end of period 826 9.68 3.5 801 6.84 1.9 Unvested at end of period 75 15.74 9.6 400 11.16 6.7 Vested and expected to vest at end of period 779 $ 10.16 7.8 1,078 $ 8.08 4.5 As a result of the 2014 Initial Public Offering (See Note 1), all unvested stock options from prior issuances immediately vested.

The restricted stock generally vest ratably over a five-year period from the original restricted stock grant date, contingent on the employee’s continuous employment by ADS. In certain instances, however, a portion of the grants vested immediately or for accounting purposes were deemed to have vested immediately, including the grants to the Chief Executive Officer, which do not have a substantial risk of forfeiture as a result of different vesting provisions. Under the restricted stock plan, vested shares are considered issued and outstanding. Employees with restricted stock have the right to dividends on the shares awarded (vested and unvested) in addition to voting rights on non-forfeited shares. The Company recognized compensation expense of $78 and $(40) for the three months ended December 31, 2014 and 2013, respectively, and $1,626 and $1,138 for the nine months ended December 31, 2014 and 2013, respectively, relating to the issuance of these shares; of this amount, $0 and $385 relates to the restricted shares that vested immediately during the nine months ended December 31, 2014 and 2013, respectively. We had approximately 333 shares available for granting under this plan as of December 31, 2014. The following table summarizes information about the unvested restricted stock grants as of December 31, 2014: Number of Shares Weighted Average Grant Date Fair Value Unvested at beginning of period 311 $ 12.40 Granted — — Vested 123 10.99 Forfeited 3 10.66 Unvested at end of period 185 $ 11.45 We expect most, if not all, restricted stock grants to vest. As of December 31, 2014, there was approximately $1,723 of unrecognized compensation expense related to the restricted stock that will be recognized over the remaining service period. Non-Employee Director Compensation Plan On June 18, 2014, the Company amended its then-existing Stockholders’ Agreement to authorize shares of stock to be granted to non-employee members of its Board of Directors. The number of shares authorized amounted to 282. The shares typically vest one year from the date of issuance. Under this stock plan, the vested shares granted are considered issued and outstanding. Non-employee directors with this stock have the right to dividends on the shares awarded (vested and unvested) in addition to voting rights. On September 6, 2014, a total of 48 shares were granted to seven directors at a fair market value of $18.88 per share. These shares will vest on February 27, 2015. The Company recognized compensation expense of $286 and $736 for the three and nine months ended December 31, 2014, respectively relating to the issuance of these shares. We had approximately 234 shares available for granting under this plan as of December 31, 2014.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	18. 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, such as provision to return adjustments. For the nine months ended December 31, 2014 and 2013, the Company utilized an effective tax rate of 41.8% and 57.9%, respectively, to calculate its provision for income taxes. These rates differ from the federal statutory rate of 35% due to state and local taxes, partially offset by foreign income taxed at lower rates. Furthermore, the effective tax rate for the first nine months of fiscal 2014 was primarily driven by the expected special dividend payment to participants in the ESOP Plan, which increased the effective tax rate by 23.0%.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share	19. NET INCOME (LOSS) PER SHARE Basic net income (loss) per share is calculated by dividing the Net income attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. Diluted net income (loss) per share is computed by dividing the Net income attributable to common stockholders by the weighted-average number of common share equivalents outstanding for the period. Holders of unvested restricted stock have nonforfeitable rights to dividends when declared on common stock, and holders of Redeemable convertible preferred stock participate in dividends on an as-converted basis when declared on common stock. As a result, unvested restricted stock and Redeemable convertible preferred stock meet the definition of participating securities, which requires us to apply the two-class method to compute both basic and diluted net income (loss) per share. The two-class method is an earnings allocation formula that treats participating securities as having rights to earnings that would otherwise have been available to common stockholders. The dilutive effect of stock options and unvested restricted stock is based on the more dilutive of the treasury stock method or the diluted two-class method. In computing diluted net income (loss) per share, income available to common shareholders used in the basic net income (loss) per share calculation (numerator) is adjusted, subject to sequencing rules, for certain adjustments that would result from the assumed issuance of potential common shares. Diluted net income (loss) per share assumes the Redeemable convertible preferred stock would be cash settled through the effective date of the IPO on July 25, 2014, as we have the choice of settling in cash or shares and we have demonstrated past practice and intent of cash settlement. Therefore these shares are excluded from the calculation through the effective date of the IPO. After the effective date of the IPO, Management’s intent is to share settle; therefore, these shares are included in the calculation from July 26, 2014 through December 31, 2014, if dilutive. For purposes of the calculation of diluted net income (loss) per share, stock options and unvested restricted stock are considered to be potential common stock and are only included in the calculations when their effect is dilutive. The Company’s Redeemable common stock is included in the weighted-average number of common shares outstanding for calculating basic and diluted net income (loss) per share. The following table presents information necessary to calculate net income (loss) per share for the three and nine months ended December 31, 2014 and 2013, as well as potentially dilutive securities excluded from the weighted average number of diluted common shares outstanding because their inclusion would have been anti-dilutive: Three Months Ended Nine Months Ended (Amounts in thousands, except per share data) 2014 2013 2014 2013 Net income (loss) per share - Basic Net (loss) income attributable to ADS $ (3,325 ) $ (4,877 ) $ 22,085 $ 22,837 Adjustment for: Change in fair value of redeemable convertible preferred stock — (4,697 ) (11,054 ) (8,492 ) Dividends to redeemable convertible preferred stock (298 ) (209 ) (377 ) (640 ) Dividends paid to unvested restricted stockholders (9 ) (8 ) (9 ) (47 ) Net (loss) income available to common stockholders and participating securities (3,632 ) (9,791 ) 10,645 13,658 Undistributed income allocated to participating securities — — (995 ) (1,130 ) Net (loss) income available to common stockholders - Basic (3,632 ) (9,791 ) 9,650 12,528 Weighted average number of common shares outstanding - Basic 52,986 47,251 50,691 46,976 Net (loss) income per common share - Basic $ (0.07 ) $ (0.21 ) $ 0.19 $ 0.27 Net (loss) income per share - Diluted Net income (loss) available to common stockholders - Basic $ (3,632 ) $ (9,791 ) $ 9,650 $ 12,528 Undistributed income allocated to participating securities — — — — Net (loss) income available to common stockholders - Diluted (3,632 ) (9,791 ) 9,650 12,528 Weighted average number of common shares outstanding - Basic 52,986 47,251 50,691 46,976 Assumed exercise of stock options — — 515 504 Weighted average number of common shares outstanding - Diluted 52,986 47,251 51,206 47,480 Net (loss) income per common share - Diluted $ (0.07 ) $ (0.21 ) $ 0.19 $ 0.26 Potentially dilutive securities excluded as anti-dilutive 6,560 99 3,808 94

Segment Reporting [Abstract]
Business Segments Information	20. BUSINESS SEGMENTS INFORMATION We operate our business in two distinct operating and reportable segments based on the markets we serve: “Domestic” and “International”. The Chief Operating Decision Maker (“CODM”) evaluates segment reporting based on net sales and Segment Adjusted EBITDA (a non-GAAP measure). We calculate Segment Adjusted EBITDA as net income or loss before interest, income taxes, depreciation and amortization, stock-based compensation expense, non-cash charges and certain other expenses. Domestic Our Domestic segment manufactures and markets products throughout the United States. We maintain and serve these markets through strong product distribution relationships with many of the largest national and independent waterworks distributors, major national retailers as well as an extensive network of hundreds of small to medium-sized distributors across the U.S. We also sell through a broad variety of buying groups and co-ops in the United States. Products include Singlewall pipe, N-12 HDPE pipe sold into the Storm sewer and Infrastructure markets, high performance PP pipe sold into the Storm sewer and sanitary sewer markets, and our broad line of Allied Products including StormTech, Nyloplast, Arc Septic Chambers, Inserta Tee, BaySaver filters and water quality structures, Fittings, and FleXstorm. Our Domestic segment sales are diversified across all regions of the country. International Our International segment manufactures and markets products in regions outside of the United States, with a growth strategy focused on our owned facilities in Canada and through our joint-ventures, with best-in-class local partners in Mexico, Central America and South America. Our joint venture strategy provides us with local and regional access to new markets such as Brazil, Chile, Argentina, Peru and Colombia. We serve the Canadian market through Hancor of Canada. Our Mexican joint venture through ADS Mexicana primarily serves the Mexican markets, while our joint venture through the South American Joint Venture is our primary channel to serve the South American markets. Our product line includes Singlewall pipe, N-12 HDPE pipe, and high performance PP pipe. The Canadian market also sells our broad line of Allied Products, while sales in Latin America are currently concentrated in fittings and Nyloplast. The following table sets forth reportable segment information with respect to the amount of net sales contributed by each class of similar products of our consolidated gross profit for the three and nine months ended December 31, 2014 and 2013, respectively: Three Months Ended December 31, Nine Months Ended December 31, (Amounts in thousands) 2014 2013 2014 2013 Domestic Pipe $ 179,979 $ 171,452 $ 637,728 $ 582,632 Allied Products 59,236 55,308 210,888 193,763 Total domestic 239,215 226,760 848,616 776,395 International Pipe 34,171 27,630 102,320 88,230 Allied Products 6,485 6,254 22,083 21,325 Total international 40,656 33,884 124,403 109,555 Total net sales $ 279,871 $ 260,644 $ 973,019 $ 885,950 The following sets forth certain additional financial information attributable to our reportable segments for the three and nine months ended December 31, 2014 and 2013, respectively: Three Months Ended December 31, Nine Months Ended December 31, (Amounts in thousands) 2014 2013 2014 2013 Net Sales Domestic $ 239,215 $ 226,760 $ 848,616 $ 776,395 International 40,656 33,884 124,403 109,555 Total $ 279,871 $ 260,644 $ 973,019 $ 885,950 Gross Profit Domestic 41,764 49,122 161,405 156,927 International 7,414 10,220 18,394 24,353 Total $ 49,178 $ 59,342 $ 179,799 $ 181,280 Segment Adjusted EBITDA Domestic 30,298 39,592 125,195 123,018 International 3,500 7,154 8,932 17,721 Total $ 33,798 $ 46,746 $ 134,127 $ 140,739 Interest expense, net Domestic 4,613 4,543 14,675 13,903 International 18 37 51 127 Total $ 4,631 $ 4,580 $ 14,726 $ 14,030 Depreciation and amortization Domestic 14,742 14,761 44,338 43,754 International 1,376 1,337 4,181 4,054 Total $ 16,118 $ 16,098 $ 48,519 $ 47,808 Equity in net income (loss) of unconsolidated affiliates Domestic (92 ) 112 312 226 International (896 ) (1,573 ) (2,024 ) (2,205 ) Total $ (988 ) $ (1,461 ) $ (1,712 ) $ (1,979 ) Capital expenditures Domestic 4,673 4,365 19,461 23,472 International 1,012 556 1,820 3,010 Total $ 5,685 $ 4,921 $ 21,281 $ 26,482 The following sets forth certain additional financial information attributable to our reporting segments as of December 31, 2014 and March 31, 2014, respectively.

Subsequent Events [Abstract]
Subsequent Events	21. SUBSEQUENT EVENTS ASC 855, “Subsequent Events” (“ASC 855”), establishes general standards of accounting and disclosure of events that occur after the balance sheet date but before financial statements are issued or available to be issued. ASC 855 requires the Company to evaluate events that occur after the balance sheet date through the date the Company’s financial statements are issued, and to determine whether adjustments to or additional disclosures in the financial statements are necessary. The Company has evaluated subsequent events through the date these financial statements were originally issued. On January 30, 2015, Hancor of Canada, a wholly-owned subsidiary of the Company, acquired all issued and outstanding shares of Ideal Drain Tile Limited and Wave Plastics Inc., the sole partners of Ideal Pipe of Canada. Ideal Pipe designs, manufactures and markets high performance thermoplastic corrugated pipe and related water management products used across a broad range of Canadian end markets and applications, including non-residential, residential, agriculture, and infrastructure applications. The acquisition further strengthens our positions in Canada by increasing our size and scale in the market, as well as enhancing our manufacturing, marketing and distribution capabilities. The purchase price of Ideal Pipe of Canada was $55,674 Canadian dollars, financed through our existing line of credit facility. We acquired certain assets and liabilities including accounts receivable, inventory, property plant and equipment, intangible and other assets and accrued liabilities. The Company will account for this acquisition in accordance with ASC 805. Pro forma results and other expanded disclosures prescribed by ASC 805 have not been presented as the Company has not begun the process of completing the preliminary purchase accounting.

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 (“U.S. GAAP”). The Condensed Consolidated Balance Sheet as of March 31, 2014 was derived from audited financial statements. In our opinion, the accompanying unaudited condensed consolidated financial statements contain all adjustments, of a normal recurring nature, in addition to the restatement adjustments described in Note 2. Restatement of Previously Issued Financial Statements, necessary to present fairly its financial position as of December 31, 2014 and the results of operations for the three and nine months ended December 31, 2014 and 2013 and cash flows for the nine months ended December 31, 2014 and 2013. The interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, filed in our Annual Report on Form 10-K for the year ended March 31, 2015, filed concurrently with this Form 10-Q/A.
Principles of Consolidation	Principles of Consolidation Our condensed consolidated financial statements include the Company, our wholly-owned subsidiaries, our majority-owned subsidiaries, including ADS Mexicana, S.A. de C.V. (together with its affiliate ADS Corporativo, S.A. de C.V., “ADS Mexicana”), and variable interest entities (“VIEs”) of which we are the primary beneficiary. We use the equity method of accounting for equity investments where we exercise significant influence but do not hold a controlling financial interest. Such investments are recorded in Other assets in our Condensed Consolidated Balance Sheets and the related equity earnings from these investments is included in Equity in net loss of unconsolidated affiliates in our Condensed Consolidated Statements of Income. All intercompany balances and transactions have been eliminated in consolidation.
Estimates	Estimates The preparation of our condensed consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingencies and liabilities at the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Significant estimates include, but are not limited to, our allowance for doubtful accounts, inventory, useful lives of our property, plant and equipment and amortizing intangible assets, determination of the proper accounting for leases, accounting for investments, evaluation of goodwill, intangible assets and other long-lived assets for impairment, accounting for stock-based compensation and our ESOP, valuation of our Redeemable common stock and Redeemable convertible preferred stock, determination of allowances for sales returns, rebates and discounts, determination of the valuation allowance, if any, on deferred tax assets, and reserves for uncertain tax positions. Management’s estimates and assumptions are evaluated on an ongoing basis and are based on historical experience, current conditions and available information. Management believes the accounting estimates are appropriate and reasonably determined; however, due to the inherent uncertainties in making these estimates, actual results could differ from those estimates.
Property, Plant and Equipment and Depreciation Method	Property, Plant and Equipment and Depreciation Method Property, plant and equipment are recorded at cost less accumulated depreciation, with the exception of assets acquired through acquisitions, which are initially recorded at fair value. Equipment acquired under capital lease is recorded at the lower of fair market value or the present value of the future minimum lease payments. Depreciation is computed for financial reporting purposes using the straight-line method over the estimated useful lives of the related assets or the lease term, if shorter, as follows: Years Buildings 40 Machinery and equipment 3 – 15 Leasehold improvements Shorter of useful Costs of additions and major improvements are capitalized, whereas maintenance and repairs that do not improve or extend the life of the asset are charged to expense as incurred. When assets are retired or disposed, the cost and related accumulated depreciation are removed from the asset accounts and any resulting gain or loss is reflected in Loss (gain) on disposal of assets or businesses in our Condensed Consolidated Statements of Operations. Construction in progress is also recorded at cost and includes capitalized interest, capitalized payroll costs and related costs such as taxes and other fringe benefits. Interest capitalized was $0 and $316 during the three and nine months ended December 31, 2014, respectively, and $80 and $490 during the three and nine months ended December 31, 2013, respectively.
Leases	Leases Leases are reviewed for capital or operating classification at their inception. The Company uses the lower of the rate implicit in the lease or its incremental borrowing rate in the assessment of lease classification and assumes the initial lease term includes cancellable and renewal periods that are reasonably assured. For leases classified as capital leases at lease inception, we record a capital lease asset and lease financing obligation equal to the lesser of the present value of the minimum lease payments or the fair market value of the leased asset. The capital lease asset is recorded in Property, plant and equipment, net and amortized to its expected residual value at the end of the lease term using the straight-line method, and the lease financing obligation is amortized using the interest method over the lease term with the rental payments being allocated to principal and interest. For leases classified as operating leases, we record rent expense over the lease term using the straight-line method.
