Organization and Nature of Operations	Organization and Nature of Operations
	Nexeo Solutions Holdings, LLC ("Holdings") was formed on November 4, 2010 as a Delaware limited liability company. On March 31, 2011, Holdings purchased the global distribution business (the "Distribution Business") from Ashland Inc. ("Ashland"), which is referred to as the "Ashland Distribution Acquisition." Holdings is a holding company and substantially all of its operations are conducted through its primary operating subsidiary Nexeo Solutions, LLC ("Solutions") and its subsidiaries. Holdings owns the majority of the membership interests of Solutions while the remaining membership interests are owned by Nexeo Solutions Sub Holding Corp. ("Sub Holding"), a wholly owned subsidiary of Holdings. Holdings and its subsidiaries are collectively referred to as the "Company."
	The Company is a global distributor of chemicals products in North America and Asia and plastics products in North America, Europe, the Middle East and Africa ("EMEA") and Asia, and provides services for waste collection, recovery, recycling and arrangement for waste disposal in North America through its Environmental Services division. The Company also distributes composites products in Asia. The Company was a distributor of composites products in North America until July 1, 2014, when these operations were sold. In accordance with applicable accounting guidance, these North American composites operations are reflected as discontinued operations for all periods presented.
	The Company connects a network of approximately 1,300 suppliers with a diverse base of approximately 29,000 customers. The Company offers its customers products used in a broad cross section of end markets, including construction, oil and gas, household, industrial and institutional ("HI&I"), lubricants, performance coatings (including architectural coatings, adhesives, sealants and elastomers, or "CASE"), automotive, healthcare and personal care. The Company distributes approximately 27,000 products through a supply chain consisting of approximately 190 owned, leased or third-party warehouses, rail terminals and tank terminals globally.

Accounting Policies [Abstract]
Basis of Presentation and Recent Accounting Pronouncements	Basis of Presentation and Recent Accounting Pronouncements
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles ("U.S. GAAP") for interim financial information. As such, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments, except as disclosed herein) considered necessary for a fair statement have been included. Results of operations for the three and six months ended March 31, 2015 are not necessarily indicative of results to be expected for the fiscal year ending September 30, 2015. Quarterly financial data should be read in conjunction with the consolidated financial statements and accompanying notes for the fiscal year ended September 30, 2014 included in the Company’s Annual Report on Form 10-K as filed with the Securities and Exchange Commission ("SEC") on December 5, 2014.
	The condensed consolidated financial data as of September 30, 2014 presented in these unaudited condensed consolidated financial statements were derived from the Company’s audited consolidated financial statements, but do not include all disclosures required by U.S. GAAP.
	Certain prior period amounts have been reclassified to conform to the current period financial statement presentation, including the discontinued operations presentation resulting from the sale of the Company's North American composites operations in July 2014.
	During the second quarter of fiscal year 2014, the Company determined that certain inventory purchase contracts include provisions for title transfer at the shipping point. As a result, the Company should have recognized inventory and corresponding accounts payable relating to in-transit inventory shipments at period end. This caused a misstatement in the balance sheet between current assets and current liabilities as of September 30, 2013. Accordingly, the Company’s consolidated balance sheet as of September 30, 2013 was adjusted to increase inventory and accounts payable by $13.3 million, with a corresponding impact on the respective line items in the condensed consolidated statement of cash flows for the six months ended March 31, 2014 presented herein. The adjustment did not have an impact on total cash flows provided by or used in operating activities and did not have an impact on the Company’s results of operations.
	The Company does not believe that this revision has a material effect on the Company’s previously reported consolidated financial statements.
	Recent Accounting Pronouncements Adopted
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-4, Liabilities: Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date. This ASU provides guidance for the recognition, measurement, and disclosure of obligations resulting from certain joint and several liability arrangements. It will require the Company to measure those obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the Company expects to pay on behalf of its co-obligors. ASU 2013-4 also requires the Company to disclose important information related to those obligations. The Company adopted this standard during the first quarter of fiscal year 2015 and its adoption did not have a material effect on the Company’s financial position or results of operations.
	In March 2013, FASB issued ASU 2013-5, Foreign Currency Matters: Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity. This ASU clarifies pre-existing guidance regarding the treatment of cumulative translation adjustments when a parent either sells a part or all of its investment in a foreign entity. The Company adopted this standard during the first quarter of fiscal year 2015 and its adoption did not have a material effect on the Company’s financial position or results of operations.
	In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This ASU provides that a liability related to an unrecognized tax benefit should be offset against a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. The Company adopted this standard during the first quarter of fiscal year 2015 and its adoption did not have a material effect on the Company’s financial position or results of operations.
	Recent Accounting Pronouncements Not Yet Adopted
	In April 2014, the FASB issued ASU 2014-8, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This ASU changes the criteria for reporting discontinued operations while requiring expanded disclosures surrounding the assets, liabilities, income, and expenses of discontinued operations. This ASU also requires disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting. The amendments in this ASU are effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2014. Early adoption is permitted. The Company is in the process of evaluating the provisions of the ASU but currently does not expect it to have a material effect on the Company’s financial position or results of operations.
	In May 2014, the FASB issued ASU 2014-9, Revenue from Contracts with Customers (Topic 606). This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts are within the scope of other standards. This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition and most industry-specific guidance. The core principle of the ASU is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments in this ASU are effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2016. On April 29, 2015, the FASB proposed to delay the provisions of this ASU for one year. The Company is in the process of evaluating the provisions of the ASU and assessing the potential effect on the Company’s financial position or results of operations.
	In June 2014, the FASB issued ASU 2014-12, Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. This ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition and an entity should apply existing guidance in Topic 718, Compensation-Stock Compensation, as it relates to awards with performance conditions that affect vesting to account for such awards. The amendments in this ASU are effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2015. Early adoption is permitted. The Company is in the process of evaluating the provisions of the ASU and assessing the potential effect on the Company’s financial position or results of operations.
	In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This ASU defines management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The ASU is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. The Company is in the process of evaluating the provisions of the ASU but currently does not expect it to have a material effect on the Company's financial position or results of operations.
	In January 2015, the FASB issued ASU 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items ("ASU 2015-01").  This ASU eliminates the concept of an extraordinary item from U.S. GAAP. As a result, an entity will no longer be required to segregate extraordinary items from the results of ordinary operations to separately present an extraordinary item on its income statement, net of tax, after income from continuing operations or to disclose income taxes and earnings-per-share data applicable to an extraordinary item. However, the ASU retains the presentation and disclosure guidance for items that are unusual in nature and occur infrequently. The ASU is effective for the annual period beginning after December 15, 2015, and for annual periods and interim periods thereafter. The adoption of ASU 2015-01 is not expected to have a material effect on the Company’s financial position or results of operations.
	In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis ("ASU 2015-02").  This ASU is intended to improve targeted areas of the consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures. The ASU affects the consolidation evaluation for reporting organizations. In addition, the ASU simplifies and improves current U.S. GAAP by reducing the number of consolidation models. The ASU is effective for fiscal years beginning after December 15, 2015 and interim periods within those years and early adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements. The adoption of ASU 2015-02 is not expected to have a material effect on the Company’s financial position or results of operations.
	In April 2015, the FASB issued ASU 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Cost ("ASU 2015-03"). This ASU was issued as part of an initiative to reduce complexity in accounting standards. To simplify presentation of debt issuance costs, the ASU requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs would not be affected by the amendments in this ASU. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015 and interim periods within those years. The Company is in the process of evaluating the provisions of the ASU and assessing the potential effect on the Company’s financial position or results of operations.
	In April 2015, the FASB issued ASU 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting For Fees Paid in a Cloud Computing Arrangement ("ASU 2015-05"). This ASU provides guidance to customers with cloud computing arrangements that include a software license. If a cloud computing arrangement includes a software license, the customer is required to account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The ASU does not change the accounting for a customer’s accounting for service contracts. As a result of the ASU, all software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. ASU 2015-05 is effective for fiscal years beginning after December 15, 2015 and interim periods within those years and early adoption is permitted. The Company is in the process of evaluating the provisions of the ASU and assessing the potential effect on the Company’s financial position or results of operations.

	On July 1, 2014, the Company sold its North American composites operations to Composites One LLC, a Rhode Island limited liability company (the "Composites Sale"), including inventory and existing supplier and customer arrangements related to those operations. The North American composites operations met the criteria for discontinued operations. As a result, the assets and liabilities of the Company's North American composites operations have been reflected as assets and liabilities related to discontinued operations for all periods presented herein in the Company's condensed consolidated balance sheets as follows:

	1)	Included in Other current assets in the condensed consolidated balance sheets.
	2)	Included in Accrued expenses and other liabilities in the condensed consolidated balance sheets.
	3)	Included in Other noncurrent liabilities in the condensed consolidated balance sheets.
	Additionally, the operating results and cash flows related to the North American composites operations have been reflected as discontinued operations in the Company's condensed consolidated statements of operations, condensed consolidated statements of cash flows and condensed consolidated statements of other comprehensive income (loss) for the periods presented.
	Components of amounts reflected in the Company's condensed consolidated statements of operations related to discontinued operations are presented in the following table for the three and six months ended March 31, 2015 and 2014:
		Three Months Ended						Six Months Ended
		March 31,						March 31,
		2015				2014		2015			2014

	Income tax expense (benefit)	(0.2		)		0.1		(0.3		)	0.2
	Net income (loss) from discontinued operations, net of tax	—				1.5		(0.8		)	3
	In connection with the Composites Sale, the Company recorded a gain on sale of approximately $14.3 million, net of tax of approximately $1.2 million, which was reflected in the Company's operating results, related to discontinued operations in the fourth quarter of fiscal year 2014.
	Archway Sales, Inc.
	On April 1, 2014, Sub Holding acquired 100% of the outstanding shares of Archway Sales, Inc., a St. Louis, Missouri based chemicals blending and distribution business and a provider of specialty chemicals ("Archway"), and substantially all of the assets of JACAAB, LLC, a Missouri limited liability company, a related business of Archway ("JACAAB" and such acquisitions collectively, the "Archway Acquisition"). After consideration of the final working capital adjustment, the final purchase price for the Archway Acquisition was $128.7 million. Pursuant to the purchase agreement, $12.5 million of the purchase price may remain in escrow for a period of up to two years and relates to certain indemnification obligations under the purchase agreement. The escrow will be released in accordance with the terms of the purchase agreement and related escrow agreement. The Archway Acquisition was funded with approximately $10.0 million of cash on hand and approximately $119.0 million of borrowings under the Company's asset based loan facility ("ABL Facility"). Following the Archway Acquisition, Archway was converted to a limited liability company. There is no contingent consideration related to the Archway Acquisition.
	The Archway Acquisition was accounted for under the acquisition method, which required the Company to perform an allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the estimated fair values is recorded as goodwill. The following table summarizes the Company’s final allocation of the net purchase price to assets acquired and liabilities assumed at the acquisition date:
		Purchase Price
		Allocation
	Accounts receivable	$	21.5
	Inventory	16.4
	Other current assets	2.3
	Deferred tax asset - current	1.9
	Property and equipment	1.2
	Customer-related intangible	11
	Vendor-related intangible	17
	Trade name	1.9
	Non-compete agreements	3.3
	Goodwill	118.6
	Total assets acquired	195.1
	Accounts payable	9.3
	Other current liabilities	4.1
	Deferred tax liability — current	1.3
	Other non-current liabilities	1.7
	Deferred tax liability — non-current	50
	Total liabilities assumed	66.4
	Net assets acquired	$	128.7
	During the three months ended March 31, 2015, the Company completed its fair value assessment for certain contingent liabilities assumed and recorded adjustments to reflect the estimated fair value of obligations assumed as part of the transaction, and to record a minor adjustment to the fair value of property and equipment acquired. In connection with these adjustments, the Company recognized a liability for assumed contingent obligations, inclusive of income tax-related uncertainties, included in Other Non-Current Liabilities on the Company's condensed consolidated balance sheet. The contingent liabilities were valued using an expected value (probability-weighted) approach. The net impact to goodwill associated with these adjustments was $1.8 million.
	Transaction costs associated with the Archway Acquisition are included in Transaction related costs in the Company's condensed consolidated statement of operations and totaled $0.8 million and $1.2 million during the three and six months ended March 31, 2014, respectively. There were no transaction costs associated with the Archway Acquisition during the three and six months ended March 31, 2015.
	Impact of the Archway Acquisition on the Company’s Unaudited Condensed Consolidated Financial Information
	For the three months ended March 31, 2015, the Company’s condensed consolidated sales and operating revenues and net income (loss) included approximately $35.5 million and $0.6 million, respectively. For the six months ended March 31, 2015, the Company’s condensed consolidated sales and operating revenues and net income (loss) included approximately $68.0 million and $0.8 million, respectively.
	Chemical Specialists and Development, Inc.
	Effective December 1, 2013, Sub Holding acquired 100% of the outstanding shares of Chemical Specialists and Development, Inc. ("CSD"), a chemical distribution company and provider of specialty chemicals headquartered in Conroe, Texas. On the same date, Solutions acquired substantially all of the assets of STX Freight Company ("STX Freight") and ST Laboratories Group, LLC ("ST Laboratories"), two related businesses of CSD. The acquisition of CSD’s outstanding shares and substantially all the assets of STX Freight and ST Laboratories is referred to, collectively, as the "CSD Acquisition." The Company paid an aggregate purchase price of $96.4 million for the CSD Acquisition. Of the purchase price, $10.0 million was placed in escrow for a period of up to three years related to certain indemnification obligations under the purchase agreement. The escrow funds were released in May 2015 (see Note 19). The acquisition was financed with $10.0 million of cash on hand and approximately $87.0 million of borrowings under the ABL Facility. Following the CSD Acquisition, CSD and each of its subsidiaries were converted to limited liability companies. There is no contingent consideration related to the CSD Acquisition.
	The CSD Acquisition was accounted for under the acquisition method which required the Company to perform an allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the estimated fair values is recorded as goodwill.
	The following table summarizes the Company’s final allocation of the purchase price to assets acquired and liabilities assumed at the acquisition date:
		Purchase Price Allocation
	Accounts receivable	$	24.7
	Inventory	9.2
	Other current assets	1.1
	Property, plant and equipment	14.7
	Customer-related intangible	36
	Trademarks and trade names	3.5
	Non-compete agreements	5.1
Other non-current assets	0.4
Goodwill	59.1
Total assets acquired	153.8
Accounts payable	16.8
Other current liabilities	2.3
Deferred tax liability — current	0.5
Other non-current liabilities	0.5
Deferred tax liability — non-current	37.3
Total liabilities assumed	57.4
Net assets acquired	$	96.4
The purchase price allocation above is final as the Company has completed the fair value assessment for the tax impact associated with the transaction. There were no changes to the purchase price allocation during the three and six months ended March 31, 2015.
Transaction costs associated with the CSD Acquisition are included in Transaction related costs in the Company's condensed consolidated statement of operations and totaled $0.0 million and $4.8 million during the three and six months ended March 31, 2014, respectively. There were no transaction costs associated with the CSD Acquisition during the three and six months ended March 31, 2015.
Impact of the CSD Acquisition on the Company’s Unaudited Condensed Consolidated Financial Information
For the three months ended March 31, 2014, the Company’s condensed consolidated sales and operating revenues and net income (loss) includes $41.2 million and $1.3 million, respectively, related to the estimated results of operations of the acquired business for the period since the closing date of the CSD Acquisition on December 1, 2013. For the six months ended March 31, 2014, the Company’s condensed consolidated sales and operating revenues and net income (loss) includes $55.0 million and $0.5 million, respectively, related to the estimated results of operations of the acquired business for the period since the closing date of the CSD Acquisition. The six months ended March 31, 2014 includes a $1.2 million charge related to the inventory adjustment to fair value recorded during the first quarter of fiscal year 2014. The charge related to the inventory fair value adjustment is recorded in Cost of sales and operating expenses in the condensed consolidated statement of operations. Beginning on July 1, 2014, the operations, sales force and other personnel of CSD were fully integrated into the Company’s operations and ERP systems.
China Operations
In September 2012, the Company formed a joint venture, Nexeo Plaschem (Shanghai) Co., Ltd ("Nexeo Plaschem"), with the shareholders of Beijing Plaschem Trading Co., Ltd ("Beijing Plaschem") and initially owned 60% of the joint venture. On November 1, 2012, Nexeo Plaschem acquired Beijing Plaschem’s operations, including inventory and existing supplier and customer arrangements related to those operations (the "Beijing Plaschem Acquisition").
During fiscal year 2014, the Company acquired additional equity interests totaling 30% for approximately $92.2 million in cash. In October 2014, the Company acquired the remaining 10% equity interest in Nexeo Plaschem it did not already own for approximately $34.3 million in cash, which made Nexeo Plaschem a wholly-owned subsidiary beginning in October 2014. The Company funded this payment with cash on hand and approximately $18.0 million of borrowings under the ABL Facility.
From the formation of Nexeo Plaschem and through September 30, 2014, the Company consolidated 100% of the operations of Nexeo Plaschem and reflected the percentage it did not own as of the applicable reporting date as a contingently redeemable noncontrolling interest, classified as mezzanine equity (temporary equity) in the consolidated balance sheet. Additionally, the income generated or loss incurred by Nexeo Plaschem during all periods was allocated to the Company and to the noncontrolling interest based on each party’s applicable ownership percentage during each respective period.
Nexeo Plaschem is not a guarantor of the 8.375% Senior Subordinated Notes (the "Notes") issued by Solutions and Nexeo Solutions Finance Corporation (the "Co-Issuer," and together with Solutions, the "Issuers"), the ABL Facility or the senior secured term loan facility ("Term Loan Facility" and collectively, the "Credit Facilities").
Contingently Redeemable Noncontrolling Interest
As mentioned above, in October 2014, the Company acquired the remaining 10% equity interest in Nexeo Plaschem. In conjunction with this event, the noncontrolling shareholders agreed to immediately terminate their employment with Nexeo Plaschem and to effect the successful transfer of the business to the Company. The Company also entered into consulting agreements with the noncontrolling shareholders for the provision of certain transition services for a period of six months.
The following table summarizes the changes in the contingently redeemable noncontrolling interest for the six months ended March 31, 2015:
		Six Months Ended
		March 31, 2015
Beginning balance		$	3.3

	At March 31, 2015, the Company had $51.4 million in cash and cash equivalents. Of this amount, $43.8 million was held by foreign subsidiaries outside of the United States ("U.S."). Of the $43.8 million, $36.5 million was denominated in currencies other than the U.S. dollar, primarily in Canadian dollars ("CAD"), Euros, Chinese Renminbi ("RMB") and British pounds. At March 31, 2015, the Company had approximately $5.6 million in China denominated in RMB. While the RMB is convertible into U.S. dollars, foreign exchange transactions are subject to approvals from the State Approvals of Foreign Exchange ("SAFE"). The Company does not anticipate any significant adverse impact to overall liquidity from restrictions on cash and cash equivalents. Although the Company currently anticipates that the majority of the cash and cash equivalents held by foreign affiliates will be retained by the affiliates for working capital purposes, the Company believes such cash and cash equivalents could be repatriated to the U.S. in the form of debt repayments with limited tax consequences.

Derivatives	Derivatives
	The Company is a party to interest rate swap agreements of varying expiration dates through March 2017, to help manage the Company’s exposure to interest rate risk related to its variable-rate Term Loan Facility. The swaps have a quarterly settlement frequency. As of March 31, 2015, the notional amount of outstanding interest rate swap agreements was $200.0 million. The interest rate swaps are accounted for as cash flow hedges. Accordingly, gains or losses resulting from changes in fair value of the swaps are recorded in other comprehensive income to the extent that the swaps are effective as hedges. Gains or losses resulting from changes in fair value applicable to the ineffective portion, if any, are reflected in income. Gains or losses recorded in other comprehensive income are reclassified into and recognized in income when the interest expense on the Term Loan Facility is recognized.
	During the three and six months ended March 31, 2015, the Company reclassified into and recognized in income realized losses on the interest rate swaps of $0.1 million and $0.3 million, respectively, which were recorded in interest expense. During the three and six months ended March 31, 2014, the Company reclassified into and recognized in income realized losses on interest rate swaps of $0.2 million and $0.4 million, respectively. During the three and six months ended March 31, 2015, the Company recorded unrealized gains on the interest rate swaps (net of reclassifications into income) of less than $0.1 million and $0.1 million, respectively, which were recorded in other comprehensive income. During the three and six months ended March 31, 2014, the Company recorded unrealized gains on the interest rate swaps (net of reclassifications into income) of $0.1 million and $0.2 million, respectively, which were recorded in other comprehensive income. At March 31, 2015, approximately $0.5 million in unrealized losses were expected to be realized within the next twelve months.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	The accounting standard for fair value measurements establishes a framework for measuring fair value that is based on the inputs market participants use to determine the fair value of an asset or liability and establishes a fair value hierarchy to prioritize those inputs. The fair value hierarchy is as follows:
	● Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
	● Level 2—Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.
	● Level 3—Measurement is based on prices or valuation models that require inputs that are both significant to the fair value measurement and less observable for objective sources (i.e., supported by little or no market activity).
	The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs are obtained from independent sources and can be validated by a third party, whereas unobservable inputs reflect assumptions a third party would use in pricing an asset or liability based on the best information available under the circumstances. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of the assets and liabilities and their placement within the fair value hierarchy levels. The Company considers active markets as those in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
	The Company’s financial instruments recorded at fair value on a recurring basis relate solely to its interest rate swaps. The Company’s interest rate swaps are valued using quoted market prices and significant other observable and unobservable inputs. These financial instruments’ fair values are based upon trades in liquid markets and the valuation model inputs can generally be verified through over-the-counter markets and valuation techniques that do not involve significant management judgment. The fair values of these financial instruments are classified within Level 2 of the fair value hierarchy.
	At March 31, 2015, the Company recorded $0.5 million in Accrued expenses and other liabilities and $0.1 million in Other non-current liabilities in the condensed consolidated balance sheet related to these instruments. At September 30, 2014, the Company recorded $0.5 million in Accrued expenses and other liabilities and $0.2 million in Other non-current liabilities in the condensed consolidated balance sheet related to these instruments.
	During the six months ended March 31, 2015 and 2014, the Company did not have any transfers between Level 1, Level 2 or Level 3 fair value measurements.
	Fair value of financial instruments
	The carrying values of cash and cash equivalents, accounts and notes receivable, accounts payable and short-term borrowings approximate fair value due to the short-term maturity of those instruments.
	The carrying values of borrowings outstanding under the ABL Facility and the Term Loan Facility approximate fair value at March 31, 2015 and September 30, 2014, primarily due to their variable interest rate. The estimated fair value of these instruments is classified by the Company as a Level 3 measurement within the fair value hierarchy.
	The estimated fair value of the Notes was approximately $157.0 million and $174.4 million at March 31, 2015 and September 30, 2014, respectively, including accrued interest of $1.2 million and $1.2 million, respectively. The estimated fair value of the Notes is classified by the Company as a Level 3 measurement within the fair value hierarchy. The estimated fair values of these instruments are calculated based upon a pricing model using the estimated yield calculated from interpolated treasury and implied yields to quoted price as inputs. The Company’s relative credit standing is one of the inputs to the valuation.
	Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
	In addition to the financial instruments that are recorded at fair value on a recurring basis, the Company records assets and liabilities at fair value on a nonrecurring basis as required by U.S. GAAP. Generally, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges or as part of a business combination. During the three and six months ended March 31, 2015, the Company recorded nonrecurring fair value measurements related to the Archway Acquisition. See Note 3. During the three and six months ended March 31, 2014, the Company recorded nonrecurring fair value measurements related to the CSD Acquisition. These fair value measurements were classified as Level 3 within the fair value hierarchy.

	Environmental Remediation
	Due to the nature of its business, the Company is subject to various laws and regulations pertaining to the environment and to the manufacture, sale, transportation and disposal of chemicals and hazardous materials. These laws pertain to, among other things, air and water, the management of solid and hazardous wastes, transportation, and human health and safety.
	Ashland has agreed to retain all known environmental remediation liabilities listed on the schedules to the purchase agreement (the "Retained Specified Remediation Liabilities") and other environmental remediation liabilities arising prior to the closing date of March 31, 2011 for which Ashland receives written notice prior to the fifth anniversary of such closing date (the "Other Retained Remediation Liabilities") (collectively the "Retained Remediation Liabilities"). Ashland’s liability for Retained Remediation Liabilities is not subject to any claim thresholds or deductibles. However, in the event the Company was to incur expenses arising out of the Other Retained Remediation Liabilities, Ashland’s indemnification obligation is subject to an individual claim threshold of $0.2 million and an aggregate claim deductible of $5.0 million. Ashland’s indemnification obligation for the Retained Remediation Liabilities is subject to an aggregate ceiling of $75.0 million. Ashland’s indemnification obligations resulting from its breach of any representation, warranty or covenant related to environmental matters (other than for liabilities relating to taxes or the breach of any fundamental representation or warranty) are generally limited by an individual claim threshold of $0.2 million, an aggregate claim deductible of $18.6 million and a ceiling of $93.0 million. Collectively, Ashland’s indemnification obligation resulting from or relating to the Retained Remediation Liabilities, retained litigation liabilities, and the breach of Ashland’s representations, warranties and covenants contained in the purchase agreement (other than for liabilities relating to taxes or the breach of any fundamental representation or warranty) is subject to an aggregate ceiling of $139.5 million, and Ashland’s total indemnification obligation under the purchase agreement (other than for liabilities relating to taxes or any retained indebtedness) is subject to an aggregate ceiling in the amount of the purchase price for the Distribution Business net assets.
	In July 2014, Ashland filed a lawsuit styled and numbered Ashland Inc. v. Nexeo Solutions, LLC, Case No. N14C-07-243 WCC CCLD, in the Superior Court for the State of Delaware in and for New Castle County. In the suit, Ashland seeks a declaration that the Company is obligated to indemnify Ashland for losses Ashland incurs pertaining to Other Retained Remediation Liabilities, up to the amount of a $5.0 million deductible, which Ashland contends applies pursuant to the purchase agreement for the Ashland Distribution Acquisition. Ashland further alleges that the Company has breached duties related to that purchase agreement by not having so indemnified Ashland to date with respect to costs for certain Other Retained Remediation Liabilities Ashland incurred pertaining to sites at which Ashland disposed of waste prior to the Ashland Distribution Acquisition, and on that basis seeks unspecified compensatory damages, costs and attorney’s fees. The Company disagrees with Ashland’s construction of the purchase agreement and is vigorously defending the lawsuit.
	As a result, the Company does not currently have any environmental or remediation reserves for matters covered by the Ashland Distribution Acquisition agreement. However, if the Company was to incur expenses related to the Other Retained Remediation Liabilities, the Company would be responsible for the first $5.0 million in aggregate expenses relating thereto prior to the receipt of any indemnification from Ashland.  In addition, if any Retained Remediation Liability ultimately exceeds the liability ceilings described above, the Company would be responsible for such excess amounts. In either of these scenarios, the Company would be required to take an appropriate environmental or remediation reserve. The Company’s reserves will be subject to numerous uncertainties that affect its ability to accurately estimate its costs, or its share of costs if multiple parties are responsible. These uncertainties involve the legal, regulatory and enforcement parameters governing environmental assessment and remediation, the nature and extent of contamination, the extent of required remediation efforts, the choice of remediation methodology, availability of insurance coverage and, in the case of sites with multiple responsible parties, the number and financial strength of other potentially responsible parties.
	Other Legal Proceedings
	The Company is subject to various claims and legal proceedings covering a wide range of matters that arise in the ordinary course of its business activities, including product liability claims. Management believes that any liability that may ultimately result from the resolution of these matters will not have a material adverse effect on the financial condition or results of operations of the Company.
	Other Contingencies
	In June 2014, the Company self-disclosed to the California Department of Toxic Substance Control ("DTSC") that a recent inventory of its Fairfield facility had revealed potential violations of RCRA and the California Health and Safety Code. Although no formal proceeding has been initiated, the Company expects the DTSC to seek payment of fines or other penalties for non-compliance. The Company does not expect the amount of any such fine or other penalty to have a material adverse effect on its business, financial position or results of operations.

Employee Benefit Plans	Employee Benefit Plans
	Defined Contribution Plans
	Qualifying employees of the Company are eligible to participate in the Nexeo Solutions, LLC Employee Savings Plan ("401(k) Plan"). The 401(k) Plan is a defined contribution plan designed to allow employees to make tax deferred contributions as well as Company contributions, designed to assist employees of the Company and its affiliates in providing for their retirement. The Company matches 100% of employee contributions up to 4.0%. The Company will make an additional contribution to the 401(k) Plan of 1.5%, 3.0%, or 4.5%, based upon years of service of one to ten years, eleven to twenty years, and over twenty-one years of service, respectively. Employees meeting certain age requirements may also receive an additional transition contribution from the Company. A version of the 401(k) Plan is also available for qualifying employees of the Company in its foreign subsidiaries. The Company contributed a total of approximately $2.6 million and $5.5 million to the defined contribution plans in the three and six months ended March 31, 2015, respectively, and $2.9 million and $5.8 million for the three and six months ended March 31, 2014, respectively. Of the above contributions to the plans, approximately $1.8 million and $3.6 million in the three and six months ended March 31, 2015, respectively, and $1.9 million and $3.7 million in the three and six months ended March 31, 2014, respectively, were recorded as a component of selling, general and administrative expenses. The remainder was recorded as a component of cost of sales and operating expenses.
	Restricted Equity Plan
	Holdings may issue unregistered Series B units to directors, certain officers and employees eligible to participate in the Company’s restricted equity plan ("Equity Plan"). The units issued under the Equity Plan are subject to certain transfer restrictions and are initially deemed to be unvested. With respect to units issued to certain officers and employees, 50% of the Series B units vest 20% annually over a five year period ("Time-Based Units"), and 50% of the Series B units become vested in accordance with a performance-based schedule that is divided into five separate and equal twelve month periods ("Performance-Based Units"). The vesting of both the Time-Based Units and the Performance-Based Units is subject to the employee’s continued employment with the Company. The Board of Directors of the Company (the "Board of Directors") establishes each annual performance-based period based upon an earnings before interest, tax, depreciation, and amortization ("EBITDA") target for the Company during that period. In the event that any Performance-Based Units do not vest for any applicable annual performance period due to the failure to achieve that year’s EBITDA-based performance target, the Performance-Based Units assigned to that annual performance period shall subsequently vest upon the achievement of the EBITDA-based performance target for the fiscal year following such fiscal year. Upon the occurrence of a liquidity event within seven years of the employee’s beginning vesting date in which TPG Accolade, L.P. ("TPG Accolade") realizes a return based upon cash received (including dividends) divided by aggregate purchase price that is equal to or greater than 3.0x all Performance-Based Units automatically vest, as long as the employee remains employed by the Company. Furthermore, upon a termination of employment within 24 months of a change of control, all outstanding and unvested Performance-Based Units automatically vest, provided the employee remains employed by the Company at the time of the event. Upon termination of employment, the Company may, in its sole discretion, elect to redeem unregistered Series B units previously granted to officers and employees eligible to participate in the Company’s Equity Plan. The repurchase price per unit is the difference between the established threshold value at the time of redemption and the threshold value at the time of the grant.
	The fair value of the Series B units granted during the six months ended March 31, 2015 was determined using a discounted cash flow analysis and a Black-Scholes Option Pricing Model with the valuation assumptions of (1) expected term of three years, (2) expected price volatility of 39.6%, (3) a risk-free interest rate of 1.2% and (4) an expected distribution yield of 0.0%. Volatility was estimated using historical stock prices of comparable public companies.
	The Company recognized compensation expense associated with Time-Based Units of $0.3 million and $0.6 million during the three and six months ended March 31, 2015, respectively, and $0.3 million and $0.5 million during the three and six months ended March 31, 2014, respectively. There was no compensation expense recognized during the three and six months ended March 31, 2015 and 2014 related to Performance-Based Units, as the Company did not meet the pre-established EBITDA target. Expenses related to the Equity Plan are recorded as a component of selling, general and administrative expenses.
	The following table summarizes Equity Plan activity during the six months ended March 31, 2015:
		Units		Average Grant

	As discussed in Note 1, Holdings is organized as a limited liability company and is taxed as a partnership for U.S. income tax purposes. As such, with the exception of a limited number of state and local jurisdictions, Holdings is not subject to U.S. income taxes. Accordingly, the members will report their share of Holdings’ taxable income on their respective U.S. federal tax returns. Holdings pays distributions to members to fund their tax obligations. Holdings made no tax distributions to members during the three and six months ended March 31, 2015 and 2014. The Company’s sole U.S. corporate subsidiary, Sub Holding, is subject to tax at the entity level in the U.S. The Company’s controlled foreign corporations are subject to tax at the entity level in their respective jurisdictions.
	Income tax expense was $1.8 million for the three months ended March 31, 2015 compared to expense of $0.9 million for the three months ended March 31, 2014. The current period tax expense is largely attributed to a valuation allowance recorded against deferred tax assets in China as well as to U.S. income tax expense on profitable U.S. operations. The prior period tax expense is largely attributed to foreign income tax expense on profitable foreign operations. The tax expense for the three months ended March 31, 2015 reflects an effective tax rate of approximately 150.0%.
	Income tax expense was $0.9 million for the six months ended March 31, 2015 compared to expense of $3.2 million for the six months ended March 31, 2014. The current period tax expense is largely attributed to changes in the Company's valuation allowance as well as to foreign income tax expense on profitable foreign operations. The prior period tax expense is largely attributed to foreign income tax expense on profitable foreign operations. The tax expense for the six months ended March 31, 2015 reflects an effective tax rate of approximately 14.1%.
	For the periods ended March 31, 2015 and 2014, the Company computed the provision for income taxes based on the actual year-to-date effective tax rate by applying the discrete method.  Due to on-going changes in the Company’s international operations, the annual effective tax rate, which relies on accurate projections by legal entity of income earned and taxed in foreign jurisdictions, as well as accurate projections by legal entity of permanent and temporary differences, was not considered a reliable estimate for purposes of calculating year-to-date income tax expense.
	Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.
	At March 31, 2015 and September 30, 2014, the valuation allowance was $3.5 million and $2.5 million, respectively. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based upon management’s expectations at March 31, 2015, management believes it is not more likely than not that it will realize the majority of its deferred tax assets.
	Uncertain Tax Positions
	U.S. GAAP prescribes a recognition threshold and measurement attribute for the accounting and financial statement disclosure of tax positions taken or expected to be taken in a tax return. The evaluation of a tax position is a two-step process.  The first step requires the Company to determine whether it is more likely than not that a tax position will be sustained upon examination based on the technical merits of the position.  The second step requires the Company to recognize in the financial statements each tax position that meets the more likely than not criteria, measured as the amount of benefit that has a greater than 50% likelihood of being realized. Differences between the amount of tax benefits taken or expected to be taken in the income tax returns and the amount of tax benefits recognized in the financial statements represent the Company’s unrecognized income tax benefits, which are recorded as a liability.
	In connection with the CSD Acquisition, the Company recorded an initial reserve of approximately $0.5 million associated with income tax-related uncertainties. The ultimate outcome of certain of these uncertainties is covered by indemnification provisions under the purchase agreement. Accordingly, the Company also recognized indemnification assets related to certain of these income tax-related uncertainties. The indemnification assets are included in Other current assets and Other noncurrent assets in the condensed consolidated balance sheet and represent the reimbursement the Company reasonably expects to receive from funds currently held in escrow pursuant to the purchase agreement.
	During the three months ended March 31, 2015, the Company completed its evaluation of income tax-related uncertainties associated with the Archway Acquisition. In connection with the acquisition, the Company recorded an initial reserve of approximately $1.4 million associated with income tax-related uncertainties.
	The Company recognizes interest and penalties related to uncertain tax positions, if any, as a component of income tax expense in the condensed consolidated statements of operations. There was an insignificant amount of interest and penalties recognized during the three and six months ended March 31, 2015 and 2014. As of March 31, 2015 and September 30, 2014, the Company had $1.5 million and $0.4 million, respectively, related to uncertain tax positions, including related accrued interest and penalties. Between the time of the initial recording of the uncertain tax positions associated with the CSD Acquisition and the Archway Acquisition and the fiscal quarter ended March 31, 2015, the Company reduced the reserve by approximately $0.4 million due to the lapse of the applicable statute of limitations.
	The Company or one of its subsidiaries files income tax returns in various state and foreign jurisdictions. Within the U.S., the Company is subject to federal and state income tax examination by tax authorities for periods after March 2011. With respect to countries outside of the U.S., with certain exceptions, the Company’s foreign subsidiaries are subject to income tax audits for years after 2010.

Segment Reporting [Abstract]
Segment and Geographic Data	Segment and Geographic Data
	The Company operates through four lines of business, or operating segments: Chemicals, Plastics, Environmental Services and a small set of Composites operations in Asia. The lines of business market to different sets of customers operating in an array of industries, with various end markets and customer segments within those industries. Until recently, the Composites line of business included composites operations in North America which were sold on July 1, 2014 and are now classified as discontinued operations in the Company's condensed consolidated financial statements for all periods presented. For segment presentation and disclosure purposes, the Chemicals and Plastics lines of business constitute separate reportable segments while the Environmental Services line of business and the remaining composites operations in Asia do not individually meet the materiality threshold for separate disclosure and are, as a result, combined in an "Other" segment.
	Each line of business represents unique products and suppliers, and each line of business focuses on specific end markets within its industry based on a variety of factors, including supplier or customer opportunities, expected growth and prevailing economic conditions. Across the Chemicals and Plastics lines of business there are numerous industry segments, end markets, and sub markets that the Company may choose to focus on. These end markets may change from year to year depending on the underlying market economics, supplier focus, expected profitability, and the Company's strategic agenda.
	The Chemicals, Plastics and Environmental Services lines of business compete with national, regional and local companies throughout North America. Additionally, the Chemicals and Plastics lines of business compete with other distribution companies in Asia. The Plastics line of business also competes with other distribution companies in EMEA. Competition within each line of business is based primarily on the diversity of the product portfolio, service offerings, reliability of supply, technical support and price. The accounting policies used to account for transactions in each of the lines of business are the same as those used to account for transactions at the corporate level.
	The Chemicals, Plastics and Composites lines of business are distribution businesses, while the Environmental Services line of business provides hazardous and non-hazardous waste collection, recovery, recycling and arrangement for disposal services. The operations acquired during fiscal year 2014 in the CSD Acquisition and the Archway Acquisition are included in the Company’s Chemicals line of business.
	A brief description of each line of business follows:
	Chemicals. The Chemicals line of business distributes specialty and industrial chemicals, additives and solvents to industrial users primarily via rail cars, bulk tanker trucks and packaged goods in trucks and less than truckloads. The Company's chemical products are distributed in more than 50 countries worldwide, primarily in North America and Asia. While the Chemicals line of business serves multiple end markets, key end markets within the industrial space are CASE, oil and gas, HI&I, lubricants and personal care.
	Plastics. The Plastics line of business supplies a broad product line consisting of commodity polymer products and prime thermoplastic resins for plastic processors engaged in blow molding, extrusion, injection molding and rotation molding and distributes its products via rail car, bulk truck, truckload boxes and less than truckload quantities. While the plastics products are distributed in more than 50 countries worldwide, the Company primarily distributes its plastics products in North America, EMEA and Asia. The Plastics line of business serves a broad cross section of industrial segments, with a current focus on the healthcare and automotive end markets.
	Other. The Environmental Services line of business, in connection with certain waste disposal service companies, provides customers with comprehensive, nationwide hazardous and non-hazardous waste collection, recovery, recycling and arrangement for disposal services in North America, primarily in the U.S. These environmental services are offered through the Company's network of distribution facilities used as transfer facilities. The Composites line of business supplies certain resin products to a small set of customers in Asia.
	The Chief Executive Officer is the Chief Operating Decision Maker ("CODM"). The CODM reviews net sales to unaffiliated customers and gross profit in order to make decisions, assess performance and allocate resources to each line of business. In order to maintain the focus on line of business performance, certain expenses are excluded from the line of business results utilized by the Company’s CODM in evaluating line of business performance. These expenses include depreciation and amortization, selling, general and administrative expense, corporate items such as transaction related costs, interest and income tax expense. These items are separately delineated to reconcile to reported net income. No single customer accounted for more than 10.0% of revenues for any line of business for each of the periods reported. Intersegment revenues were insignificant.
	The Company aggregates total assets at the line of business level. The assets attributable to the Company’s lines of business, that are reviewed by the CODM, consist of trade accounts receivable, inventories, goodwill and any specific assets that are otherwise directly associated with a line of business. The Company’s inventory of packaging materials and containers are generally not allocated to a line of business and are included in unallocated assets.

	The following consolidating financial statements are presented pursuant to Rule 3—10 of Regulation S-X issued by the SEC. The consolidating financial statements reflect the Company’s financial position as of March 31, 2015 and September 30, 2014 and the results of operations, items of comprehensive income (loss) and cash flows for the three and six months ended March 31, 2015 and 2014.
	As a result of the Ashland Distribution Acquisition, on March 31, 2011, the Issuers issued the Notes in an aggregate principal amount of $175.0 million. The Notes are fully and unconditionally guaranteed, jointly and severally, by Holdings, and its wholly owned subsidiary, Sub Holding. The guarantees are subject to release under certain customary defeasance provisions. Solutions is also the primary borrower under the Credit Facilities, which are guaranteed by Holdings and Sub Holding. Holdings and Sub Holding are also co-borrowers on a joint and several basis with Solutions under the Credit Facilities. The Co-issuer also is a guarantor under the Term Loan Facility. The Co-issuer (labeled "Finance" in the tables below) has no independent operations and no assets or liabilities for any of the periods presented herein.
	There are no restrictions on the ability of Holdings’ subsidiaries, including the Issuers, to make investments in, or loans directly to, Holdings. The ability of Holdings’ subsidiaries, including the Issuers, to pay dividends to Holdings is restricted under the Company’s Credit Facilities, subject to certain customary exceptions. As an example, the restrictions under the Company's Term Loan Facility include that dividends may be made to Holdings (i) in an aggregate amount not to exceed the greater of $40.0 million and 3.25% of total assets, as defined, plus the amount of excluded contributions, as defined, received by Holdings prior to such payment; (ii) if the consolidated net leverage ratio, as defined, would be less than or equal to 3.0 to 1.0 after giving effect to such payment; and (iii) out of the available amount, as defined, if the consolidated net leverage ratio, as defined, would be less than or equal to 4.5 to 1.0 after giving effect to such payment. Payment of dividends described in the foregoing clauses (i), (ii) and (iii) (other than with excluded contributions, as defined) are prohibited if at the time of, or after giving effect to, the dividend, a default, as defined, would exist under the credit agreement for the Term Loan Facility.
	The Co-Issuer is a wholly owned finance subsidiary of Solutions, which jointly and severally issued the securities. Prior to December 1, 2013, Sub Holding had no independent operations and minimal assets. Effective December 1, 2013, Sub Holding acquired 100% of CSD’s outstanding shares. Following the CSD Acquisition, CSD and each of its subsidiaries were converted to limited liability companies (the "CSD Conversion"). Following the CSD Conversion, Sub Holding assigned $23.0 million of its long-term debt to Solutions and contributed its ownership interest in CSD to Solutions in exchange for a participating preferred interest in Solutions (the "CSD Contribution"). The preferred interest participates with common interests as the equivalent of a 2% common interest, and also has a preference with respect to income and distributions from Solutions that provides an annual return equal to 8% on the value of the preferred interest at the time of the CSD Contribution. Following the CSD Contribution, CSD and its subsidiaries became wholly owned subsidiaries of Solutions and guarantors of the Notes.
	Following the Archway Acquisition, Archway was converted to a limited liability company (the "Archway Conversion"). Following the Archway Conversion, Sub Holding assigned $36.0 million of its long-term debt to Solutions and contributed its ownership interest in Archway to Solutions in exchange for a participating preferred interest in Solutions (the "Archway Contribution"). The preferred interest participates with common interests as the equivalent of a 2% common interest, and also has a preference with respect to income and distributions from Solutions that provides an annual return equal to 8% on the value of the preferred interest at the time of the Archway Contribution. Following the Archway Contribution, Archway became a wholly owned subsidiary of Solutions and guarantor of the Notes.
	The remaining subsidiaries ("Non-Guarantor Subsidiaries") as of March 31, 2015 are not guarantors of the Notes.
	The condensed consolidating financial statements for the Company are as follows:

Basis of Presentation and Recent Accounting Pronouncements (Policies)	6 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles ("U.S. GAAP") for interim financial information. As such, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments, except as disclosed herein) considered necessary for a fair statement have been included. Results of operations for the three and six months ended March 31, 2015 are not necessarily indicative of results to be expected for the fiscal year ending September 30, 2015. Quarterly financial data should be read in conjunction with the consolidated financial statements and accompanying notes for the fiscal year ended September 30, 2014 included in the Company’s Annual Report on Form 10-K as filed with the Securities and Exchange Commission ("SEC") on December 5, 2014.
	The condensed consolidated financial data as of September 30, 2014 presented in these unaudited condensed consolidated financial statements were derived from the Company’s audited consolidated financial statements, but do not include all disclosures required by U.S. GAAP.
	Certain prior period amounts have been reclassified to conform to the current period financial statement presentation, including the discontinued operations presentation resulting from the sale of the Company's North American composites operations in July 2014.
	During the second quarter of fiscal year 2014, the Company determined that certain inventory purchase contracts include provisions for title transfer at the shipping point. As a result, the Company should have recognized inventory and corresponding accounts payable relating to in-transit inventory shipments at period end. This caused a misstatement in the balance sheet between current assets and current liabilities as of September 30, 2013. Accordingly, the Company’s consolidated balance sheet as of September 30, 2013 was adjusted to increase inventory and accounts payable by $13.3 million, with a corresponding impact on the respective line items in the condensed consolidated statement of cash flows for the six months ended March 31, 2014 presented herein. The adjustment did not have an impact on total cash flows provided by or used in operating activities and did not have an impact on the Company’s results of operations.
	The Company does not believe that this revision has a material effect on the Company’s previously reported consolidated financial statements.
Recent Accounting Pronouncements Adopted	Recent Accounting Pronouncements Adopted
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-4, Liabilities: Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date. This ASU provides guidance for the recognition, measurement, and disclosure of obligations resulting from certain joint and several liability arrangements. It will require the Company to measure those obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the Company expects to pay on behalf of its co-obligors. ASU 2013-4 also requires the Company to disclose important information related to those obligations. The Company adopted this standard during the first quarter of fiscal year 2015 and its adoption did not have a material effect on the Company’s financial position or results of operations.
	In March 2013, FASB issued ASU 2013-5, Foreign Currency Matters: Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity. This ASU clarifies pre-existing guidance regarding the treatment of cumulative translation adjustments when a parent either sells a part or all of its investment in a foreign entity. The Company adopted this standard during the first quarter of fiscal year 2015 and its adoption did not have a material effect on the Company’s financial position or results of operations.
	In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This ASU provides that a liability related to an unrecognized tax benefit should be offset against a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. The Company adopted this standard during the first quarter of fiscal year 2015 and its adoption did not have a material effect on the Company’s financial position or results of operations.
	Recent Accounting Pronouncements Not Yet Adopted
	In April 2014, the FASB issued ASU 2014-8, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This ASU changes the criteria for reporting discontinued operations while requiring expanded disclosures surrounding the assets, liabilities, income, and expenses of discontinued operations. This ASU also requires disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting. The amendments in this ASU are effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2014. Early adoption is permitted. The Company is in the process of evaluating the provisions of the ASU but currently does not expect it to have a material effect on the Company’s financial position or results of operations.
	In May 2014, the FASB issued ASU 2014-9, Revenue from Contracts with Customers (Topic 606). This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts are within the scope of other standards. This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition and most industry-specific guidance. The core principle of the ASU is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments in this ASU are effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2016. On April 29, 2015, the FASB proposed to delay the provisions of this ASU for one year. The Company is in the process of evaluating the provisions of the ASU and assessing the potential effect on the Company’s financial position or results of operations.
	In June 2014, the FASB issued ASU 2014-12, Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. This ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition and an entity should apply existing guidance in Topic 718, Compensation-Stock Compensation, as it relates to awards with performance conditions that affect vesting to account for such awards. The amendments in this ASU are effective for fiscal years (and interim reporting periods within those years) beginning after December 15, 2015. Early adoption is permitted. The Company is in the process of evaluating the provisions of the ASU and assessing the potential effect on the Company’s financial position or results of operations.
	In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This ASU defines management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The ASU is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. The Company is in the process of evaluating the provisions of the ASU but currently does not expect it to have a material effect on the Company's financial position or results of operations.
	In January 2015, the FASB issued ASU 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items ("ASU 2015-01").  This ASU eliminates the concept of an extraordinary item from U.S. GAAP. As a result, an entity will no longer be required to segregate extraordinary items from the results of ordinary operations to separately present an extraordinary item on its income statement, net of tax, after income from continuing operations or to disclose income taxes and earnings-per-share data applicable to an extraordinary item. However, the ASU retains the presentation and disclosure guidance for items that are unusual in nature and occur infrequently. The ASU is effective for the annual period beginning after December 15, 2015, and for annual periods and interim periods thereafter. The adoption of ASU 2015-01 is not expected to have a material effect on the Company’s financial position or results of operations.
	In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis ("ASU 2015-02").  This ASU is intended to improve targeted areas of the consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures. The ASU affects the consolidation evaluation for reporting organizations. In addition, the ASU simplifies and improves current U.S. GAAP by reducing the number of consolidation models. The ASU is effective for fiscal years beginning after December 15, 2015 and interim periods within those years and early adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements. The adoption of ASU 2015-02 is not expected to have a material effect on the Company’s financial position or results of operations.
	In April 2015, the FASB issued ASU 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Cost ("ASU 2015-03"). This ASU was issued as part of an initiative to reduce complexity in accounting standards. To simplify presentation of debt issuance costs, the ASU requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs would not be affected by the amendments in this ASU. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015 and interim periods within those years. The Company is in the process of evaluating the provisions of the ASU and assessing the potential effect on the Company’s financial position or results of operations.
	In April 2015, the FASB issued ASU 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting For Fees Paid in a Cloud Computing Arrangement ("ASU 2015-05"). This ASU provides guidance to customers with cloud computing arrangements that include a software license. If a cloud computing arrangement includes a software license, the customer is required to account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The ASU does not change the accounting for a customer’s accounting for service contracts. As a result of the ASU, all software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. ASU 2015-05 is effective for fiscal years beginning after December 15, 2015 and interim periods within those years and early adoption is permitted. The Company is in the process of evaluating the provisions of the ASU and assessing the potential effect on the Company’s financial position or results of operations.
