Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Litigation	Commitments, Contingencies and Litigation 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 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. On March 31, 2011, Holdings purchased certain assets of the global distribution business (the “Distribution Business”) from Ashland (the “Ashland Distribution Acquisition”), evidenced by the ADA Purchase Agreement. In the ADA Purchase Agreement, Ashland agreed to retain all known environmental remediation liabilities (“Retained Specified Remediation Liabilities”) and other environmental remediation liabilities unknown at the closing of the Ashland Distribution Acquisition related to the Distribution Business for which Ashland receives notice prior to the fifth anniversary of the closing (“Other Retained Remediation Liabilities”) (collectively “Retained Remediation Liabilities”). Ashland’s liability for Retained Remediation Liabilities is not subject to any claim thresholds or deductibles other than expenses the Predecessor incurs arising out of the Other Retained Remediation Liabilities; if the Predecessor incurs expenses arising out of Other Retained Remediation Liabilities for which Ashland received notice prior to March 31, 2016, 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 obligations 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 ADA 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 ADA 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. Ashland’s indemnification obligations under the ADA Purchase Agreement as described above terminated as of March 31, 2016, other than for Retained Specified Remediation Liabilities and for Other Retained Remediation liabilities reported to Ashland prior to March 31, 2016 for which Ashland retains liability pursuant to the ADA Purchase Agreement. As a result, any environmental remediation liabilities reported to the Company after March 31, 2016 and not arising out of a Retained Remediation Liability will be liabilities of the Company. In July 2014, Ashland filed a lawsuit numbered Ashland Inc. v. Nexeo Solutions, LLC, Case No. N14C-07-243 JTV CCLD, in the Superior Court for the State of Delaware in and for New Castle County. In the suit, Ashland seeks a declaration that, pursuant to the ADA Purchase Agreement, Solutions is obligated to indemnify Ashland for losses Ashland incurs pertaining to Other Retained Remediation Liabilities, up to the amount of the aggregate $5.0 million deductible applicable expenses incurred by Solutions, whether or not Solutions incurs any expenses or obtains any indemnity from Ashland. Ashland further alleges that Solutions has breached duties related to the ADA Purchase Agreement by not having so indemnified Ashland for amounts Ashland has incurred for Other Retained Remediation Liabilities at sites where Ashland disposed of wastes 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 ADA Purchase Agreement and is vigorously defending the lawsuit. The Company does not currently have any environmental or remediation reserves for matters covered by the ADA Purchase Agreement. However, if the Company had incurred expenses related to Other Retained Remediation Liabilities, the Company would have been responsible for the first $5.0 million in aggregate expenses relating thereto prior to receiving any indemnification from Ashland. Ashland’s indemnification obligations for Other Retained Remediation Liabilities ended on March 31, 2016 and, as of that date, the Company had not incurred any expenses related to Other Retained Remediation Liabilities. 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 either expense the cost of the liabilities or take an appropriate environmental or remediation reserve. The Company could also be required to take remediation or environmental reserves for remediation or other environmental liabilities reported after March 31, 2016 related to facilities acquired in the Ashland Distribution Acquisition; for remediation of spills or releases caused by the Company’s operations including those related to the Company’s Environmental Services line of business; and for remediation or other environmental liabilities related to facilities acquired from parties other than Ashland (i.e., acquisitions made by the Predecessor after the Ashland Distribution Acquisition). 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 Predecessor self-disclosed to the California DTSC that an inventory of its Fairfield facility had revealed potential violations of the Resource Conservation and Recovery Act 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.
