Forward-Looking Statements

Certain information and statements contained in this Quarterly Report on Form 10-Q are forward-looking statements within the meaning of the PSLRA codified at Section 27A of the Securities Act, and Section 21E of the Exchange Act. This statement is included for purposes of complying with the safe harbor provisions of the PSLRA. Forward-looking statements include statements regarding our expectations, beliefs, intentions, plans, objectives, goals, strategies, future events or performance and underlying assumptions and other statements that are other than statements of historical facts. These statements may be identified, without limitation, by the use of forward-looking terminology such as “anticipate,” “assume,” “believe,” “estimate,” “expect,” “intend,” “plan,” “project,” “may,” “will,” “could,” “would” and similar expressions. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider any such list to be a complete set of all potential risks, including cybersecurity risks, or uncertainties, and we urge you not to place undue reliance on any forward-looking statements, which reflect management’s current expectations and assumptions about future events, and which are based on currently available information as to the timing and outcome of future events. Certain forward-looking statements are included in this Quarterly Report on Form 10-Q, principally in the section captioned “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.” When considering forward-looking statements, you should keep in mind the risk factors and other cautionary statements set forth in our Annual Report on Form 10-K for the fiscal year ended September 30, 2017 filed with the SEC on December 7, 2017.

These forward-looking statements are based on our current expectations and beliefs concerning future developments and their potential effect on us. While management believes that these forward-looking statements are reasonable as and when made, there can be no assurance that future developments affecting us will be those that we anticipate. Unless otherwise indicated or the context otherwise requires, comments concerning our expectations for future revenues and operating results are based on our forecasts for our existing operations and do not include the potential impact of any future acquisitions. Our forward-looking statements involve significant risks and uncertainties (some of which are beyond our control) and assumptions that could cause actual results to differ materially from our historical experience and our present expectations or projections. These factors are not necessarily all of the important factors that could cause actual results to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could have material adverse effects on our future results. Our future results will depend upon various other risks and uncertainties, including those described in the section captioned “Item 1A. Risk Factors” in Part I of our Annual Report on Form 10-K for the fiscal year ended September 30, 2017 filed with the SEC on December 7, 2017. Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date of this Quarterly Report on Form 10-Q. We undertake no obligation to update or revise any forward-looking statements after the date they are made, whether as a result of new information, future events or otherwise. All forward-looking statements attributable to us are qualified in their entirety by this cautionary statement.

           The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with 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, 2018 are not necessarily indicative of results to be expected for the fiscal year ending September 30, 2018. Quarterly financial data should be read in conjunction with the consolidated financial statements and accompanying notes for the fiscal year ended September 30, 2017 included in the Company's Annual Report on Form 10-K filed with the SEC on December 7, 2017.

           The consolidated financial data as of September 30, 2017 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.

2. Recent Accounting Pronouncements

Recent Accounting Pronouncements Adopted

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. The amendments in this ASU require an entity to measure inventory at the lower of cost or net realizable value, whereas guidance previously required an assessment of market value of inventory, with different possibilities for determining market value. This ASU is effective for fiscal years beginning after December 15, 2016 and interim periods within those years and early adoption is permitted. The Company adopted this standard as of October 1, 2017, and it did not have a material effect on the Company’s financial position or results of operations.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The updated guidance simplifies several aspects of accounting for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as the classification of related matters in the statement of cash flows. This ASU is effective for annual reporting periods beginning after December 15, 2016 and interim periods within those annual periods. The Company adopted this standard as of October 1, 2017 and it did not have a material effect on the Company’s financial position or results of operations.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): This ASU clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as a modified award. The new guidance will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications.  The amendments in this ASU will be applied prospectively to awards modified on or after the adoption date. The Company adopted this standard as of October 1, 2017 and it did not have a material effect on the Company’s financial position or results of operations.

The Company continues the evaluation of the potential effects on its financial position or results of operations of the accounting pronouncements disclosed in its consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2017 filed with the SEC on December 7, 2017, including ASU 2014-09, Revenue from Contracts with Customers and ASU 2016-02, Leases. With regards to ASU 2014-09, the Company continues to work on the identification, design and implementation of changes to its accounting systems, policies and internal controls to support the recognition and disclosure requirements under the new revenue recognition standard. However, the Company does not anticipate the adoption of the guidance will have a material effect on the amount or the timing of revenue recognition associated with the majority of its customer contracts given their general terms and duration. The Company expects to utilize the modified retrospective method of adoption by recognizing the cumulative effect of the adoption change as an adjustment to beginning of period retained earnings for the first quarter of fiscal 2019.

The Company is in the process of evaluating the potential effects of ASU 2016-02 and is formulating its implementation plan, including potential changes to accounting systems, policies and internal controls to support the adoption of the new guidance.

3. Acquisitions

Ultra Chem Acquisition

On April 3, 2017, the Company completed the Ultra Chem Acquisition for $56.7 million, net of cash acquired of $0.5 million, pursuant to the Ultra Chem Stock Purchase Agreement.  As of March 31, 2018, $9.7 million of the purchase price may remain in escrow for a period of up to five years from the closing of the acquisition and relates to indemnification obligations under the Ultra Chem Stock Purchase Agreement. The escrow amount will be released pursuant to the terms of the Ultra Chem Stock Purchase Agreement and related documentation. The Ultra Chem Acquisition was financed with approximately $58.0 million of borrowings under the ABL Facility. There is no contingent consideration related to the Ultra Chem Acquisition.

Purchase Price Allocation

The Ultra Chem Acquisition is accounted for under the acquisition method, which requires the Company to perform an allocation of the purchase consideration to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase consideration over the estimated fair values is recorded as goodwill. The following table summarizes the Company’s allocation of the purchase consideration to assets acquired and liabilities assumed at the Ultra Chem Closing Date:

	Purchase Consideration Allocation
Accounts receivable	$	13.7
Inventory	9.1
Other current assets	2.4
Property and equipment	0.5
Customer-related intangible	24.0
Trade name	0.3
Non-compete agreements	3.9
Other non-current assets	2.5
Goodwill	28.0
Total assets acquired	84.4
Short-term borrowings	0.9
Accounts payable	12.1
Other current liabilities	4.1
Deferred tax liability — non-current	8.4
Other non-current liabilities	2.2
Total liabilities assumed	27.7
Net assets acquired	$	56.7

During the three months ended March 31, 2018, the Company completed its assessment of the fair values of the assets acquired and liabilities assumed in the Ultra Chem Acquisition. The Company recorded no material adjustments to the fair value estimates of assets and liabilities during the current period.

There were no transaction costs incurred by the Company associated with the Ultra Chem Acquisition during the three months endedMarch 31, 2018. Transaction costs incurred by the Company associated with the Ultra Chem Acquisition were $0.1 million during the six months ended March 31, 2018 and $0.1 million during the three and six months ended March 31, 2017.

A summary and description of the acquired assets and assumed liabilities fair valued in conjunction with applying the acquisition method of accounting follows:

14

Accounts Receivable

Accounts and notes receivable consisted of receivables related to the customers of the acquired business, as well as various other miscellaneous receivables. The accounts receivable and other miscellaneous receivables were recorded at their approximate fair value based on expected collections of the Ultra Chem Group. Accordingly, accounts receivable included an adjustment of $1.5 million to reduce gross receivables to their net value after consideration of expected uncollectable amounts at the Ultra Chem Closing Date.

Inventory

Inventory consisted primarily of finished products to be distributed to the acquired business’s customers. The fair value of inventory was established through application of the income approach, using estimates of selling prices and costs such as selling and marketing expenses to be incurred in order to dispose of the finished products and arriving at the future profitability expected to be generated once the inventory is sold (net realizable value). The inventory fair value step up of $1.0 million was recognized in Cost of sales and operating expenses during the fiscal year ended September 30, 2017.

Other Current Assets

Other current assets consisted primarily of prepaid expenses and did not have a fair value adjustment as part of acquisition accounting since their carrying value approximated fair value. Other current assets also include indemnification assets recorded in connection with the recognition of tax-related contingent liabilities assumed. The indemnification assets represent the reimbursement the Company would reasonably expect to receive from funds initially held in escrow pursuant to the purchase agreement if the liabilities were asserted by the relevant tax authority.

Property and Equipment

Property and equipment acquired consists primarily of leasehold improvements, computer and office equipment as well as furniture and fixtures. The purchase price allocation for property and equipment was based on the carrying value of such assets as it was determined to approximate fair value.

Customer-Related Intangible

Customer relationships were valued through the application of the income approach. Under this approach, revenue, operating expenses and other costs associated with existing customers were estimated in order to derive cash flows attributable to the existing customer relationships. The resulting estimated cash flows were then discounted to present value to arrive at the fair value of existing customer relationships as of the valuation date. The value associated with customer relationships will be amortized on a straight-line basis over a ten-year period, which represents the approximate point in the projection period in which a majority of the asset’s cash flows are expected to be realized based on assumed attrition rates. The Company recognized $24.0 million for these intangible assets as part of the allocation of the purchase consideration.

Trade Name

The "Ultra Chem" trade name was valued through application of the income approach, involving the estimation of likely future sales and an estimated royalty rate reflective of the rate that a market participant would pay to use the "Ultra Chem" name. The fair value of this asset will be amortized on a straight-line basis over a two-year period, estimated based on the period in which the Company would expect a market participant to use the name prior to rebranding. The Company recognized $0.3 million for this intangible asset as part of the allocation of the purchase consideration.

15

Non-Compete Agreements

In connection with the Ultra Chem Acquisition, the former equityholders of the Ultra Chem Group agreed to non-compete agreements. The terms of the non-compete agreements prohibit the equityholders from competing in the chemical distribution space for three years after the Ultra Chem Closing Date. The income approach was used to value the non-compete agreements through a comparative discounted cash flow analysis based on the impact of competition absent these agreements. The Company recognized $3.9 million for this intangible asset as part of the allocation of the purchase consideration. This intangible is amortized on a straight-line basis over a three-year period.

Other Non-Current Assets

Other non-current assets acquired represented certain long-term deposits and other assets, which did not have a fair value adjustment as part of acquisition accounting since their carrying value approximated fair value. Other non-current assets also included indemnification assets recorded in connection with the recognition of tax-related contingent liabilities assumed, and the expected value of certain assets pledged as a guarantee to the Ultra Chem Group in connection with transactions with a particular customer. The indemnification assets represent the reimbursement the Company reasonably expects to receive from funds initially held in escrow pursuant to the purchase agreement if the related liabilities were asserted by the relevant tax authority.

Goodwill

Goodwill represents the excess of the total purchase price over the fair value of the underlying net assets, largely arising from synergies expected as a result of the Ultra Chem Acquisition. Goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually, absent any indicators of impairment. The Company does not expect any goodwill from the Ultra Chem Acquisition to be deductible for tax purposes.

Short-Term Borrowings

Short-term borrowings included short-term borrowings of the Ultra Chem Group prior to the Ultra Chem Acquisition, which did not have a fair value adjustment as part of acquisition accounting as their carrying value approximated fair value. The balance was paid off immediately after the closing of the Ultra Chem Acquisition.

Accounts Payable

Accounts payable represented short-term obligations owed to the vendors of the acquired business, which were assumed in the Ultra Chem Acquisition. These obligations did not have a fair value adjustment as part of acquisition accounting as their carrying value approximated fair value.

Other Current Liabilities

Other current liabilities represented primarily accrued expenses, including accrued payroll, certain accrued taxes, the current portion of assumed tax-related contingent liabilities and various other liabilities arising out of the normal operations of the acquired business. The majority of these liabilities did not have a fair value adjustment as their carrying value approximated fair value.

Other Non-Current Liabilities

Other non-current liabilities represent assumed tax-related contingent liabilities, and the expected value of certain assets pledged as a guarantee to the Ultra Chem Group which would have to be returned to the third party under certain circumstances.

16

Deferred Taxes

Deferred tax assets and liabilities are attributable to the difference between the estimated fair values allocated to inventory, property and equipment and identified intangibles acquired for financial reporting purposes and the amounts determined for tax reporting purposes and give rise to temporary differences.  The deferred tax assets and liabilities will reverse in future periods or have reversed as the related tangible and intangible assets are amortized, acquired inventory is sold, or if goodwill is impaired.

Due to Related Party Pursuant to ContingentConsideration Obligations

Contingent Consideration - Deferred Cash Consideration

The contingent consideration associated with the Deferred Cash Consideration willbe an amount in cash equal to the prevailing price of the Company’s common stock at the time that the Company pays such deferred cash payment multiplied by the number of Excess Shares (5,178,642 Excess Shares as of March 31, 2018).  Based on the terms of the Excess Shares, certain circumstances require the Company to pay all or a portion of the Deferred Cash Consideration to the Selling Equityholders, where such cash amount is calculated as set forth in the Merger Agreement, including (i) where the volume weighted average trading price of the Company’s common stock for any period of 20 trading days in any 30 trading day period exceeds $15.00 per share, and (ii) if any Excess Shares remain on June 30, 2021. If any Excess Shares remain on June 30, 2021, the Company must elect to either (i) within five business days of such date, pay the Selling Equityholders an amount in cash equal to the product of the number of remaining Excess Shares multiplied by the volume weighted-average trading price for the 20 trading day period immediately preceding such date or (ii) use reasonable best efforts to sell such shares to a third party in a primary offering and pay the gross proceeds thereof (less any underwriting discounts and commissions) to the Selling Equityholders. However, to the extent the number of shares issued in such offerings does not equal the full amount of Excess Shares remaining at the time of the offering, the Company’s obligations with respect to any remaining Excess Shares, including the obligation to continue to complete any necessary additional offerings, shall continue.

In order to estimate the fair value of the Deferred Cash Consideration, the Company estimates the value of the Excess Shares using a Monte Carlo simulation model. The estimated fair value of the Deferred Cash Consideration liability was $54.2 million and $35.1 millionas of March 31, 2018 and September 30, 2017, respectively. See Note 9.

Contingent Consideration - TRA

Concurrent with the completion of the Business Combination, the Company incurred the liability for contingent consideration related to the TRA, which reflects amounts owed to the Selling Equityholders. This liability generally provides for the payment by the Company to the Selling Equityholders of 85% of the net cash savings, if any, in U.S. federal, state and local income taxes that the Company actually realizes (or is deemed to realize in certain circumstances) in periods after the Closing Date as a result of (i) certain increases in tax basis resulting from the Company Merger, (ii) certain tax attributes of Holdings existing prior to the Mergers, (iii) net operating losses and certain other tax attributes of Blocker available to the Company as a result of the Blocker Merger and (iv) imputed interest deemed to be paid by the Company as a result of, and additional tax basis arising from, payments the Company makes under the TRA. The Company will retain the benefit of the remaining 15% of the net cash savings, if any. The Company estimated the fair value of the TRA liability based on a discounted cash flow model which incorporates assumptions of projected taxable income, projected income tax liabilities and an estimate of tax benefits expected to be realized as a result of the Business Combination. The current undiscounted cash flows associated with the TRA liability were estimated to be approximately $136.6 million over the time period during which the tax benefits are expected to be realized, currently estimated at over 20 years. The estimated fair value of the TRA liability is $75.8 million and $105.1 million as of March 31, 2018 and September 30, 2017, respectively. See Note 9. The decrease in the liability is reflective of the provisional impact associated with the Tax Act enacted in December 2017 (see Note 15), which lowers the Company’s projected income tax liabilities, the estimate of tax benefits expected to be realized as a result of the Business Combination and the ultimate amount expected to be paid by the Company to the Selling Equityholders.

The amount and timing of any payments due under the TRA will vary depending upon a number of factors, including the amount and timing of the taxable income the Company generates in the future and the U.S. federal, state and local income tax rates then applicable. In addition, payments made under the TRA will give rise to additional tax benefits for the Company and therefore additional potential payments due under the TRA. The term of the TRA commenced upon the consummation of the Mergers and will continue until all tax benefits that are subject to the TRA have been utilized or expired, unless the Company exercises its right to terminate the TRA early. If the Company elects to terminate the TRA early, its obligations under the TRA would accelerate and it generally would be required to make an immediate payment equal to the present value of the anticipated future payments to be made by it under the TRA, calculated in accordance with certain valuation assumptions set forth in the TRA.

The facilities do not currently meet the criteria for held-for-sale classification; accordingly, they remain classified as held and used.

During the fourth quarter of fiscal year 2017, the Company entered into a purchase agreement to buy land currently leased at one of the Company's distribution centers. The purchase is expected to be finalized during late fiscal year 2018 or during fiscal year 2019 for approximately $10.8 million.

Facility Lease

As a result of the sale in September 2016 of the Company’s Franklin Park facility to the Illinois Tollway Authority under an eminent domain proceeding, the Company relocated operations to a new leased facility in Montgomery, Illinois. During the three and six months ended March 31, 2017, the Company recorded a gain of $0.2 million and $2.7 million, respectively, related to capital expenditures incurred in connection with the relocation and reimbursed by the Illinois Tollway Authority, which is included in Other Income on the condensed consolidated statements of operations.

6. Goodwill and Other Intangibles

Goodwill

The following is a progression of goodwill by reportable segment: 

	Chemicals			Plastics		Other		Total
Balance at September 30, 2017	$	362.8		$	276.7	$	63.5	$	703.0

Balance at March 31, 2018	$	362.7		$	280.0	$	63.5	$	706.2

Goodwill amounts by reportable segment at March 31, 2018 include the allocation of the purchase consideration of the Ultra Chem Acquisition as of the Ultra Chem Closing Date. See Note 3.

20

Goodwill Impairment Test

Goodwill is tested for impairment annually as of March 31 and whenever events or circumstances make it more likely than not that an impairment may have occurred. Goodwill is reviewed for impairment at the reporting unit level, or operating segment, for the Company. The Company performed an impairment test as of March 31 2018 and concluded that goodwill was not impaired. For purposes of the impairment testing of the Company's recognized goodwill, fair value measurements are determined using the income approach, based largely on inputs that are not observable to active markets, which would be deemed Level 3 fair value measurements as defined in Note 9.

The evaluation of goodwill requires the use of estimates about future operating results of each reporting unit to determine its estimated fair value. Changes in forecasted operations can materially affect these estimates, which could materially affect the Company’s results of operations. The estimate of fair value requires significant judgment and is based on management’s fair value estimates on assumptions that are believed to be reasonable but that are unpredictable and inherently uncertain, including: estimates of future growth rates, operating margins and assumptions about the overall economic climate as well as the competitive environment for the reporting units. There can be no assurance that these estimates and assumptions made for purposes of the goodwill testing as of the time of testing will prove to be accurate. If assumptions regarding business plans, competitive environments or anticipated growth rates are not correct, the Company may be required to record goodwill impairment charges in future periods, whether in connection with future annual impairment testing, or earlier, if an indicator of an impairment is present prior to the next annual evaluation.

Obligations under the ABL Facility are secured by a first priority lien on all ABL Facility first lien collateral, including eligible inventory and accounts receivable of the ABL Borrowers, and a second priority lien on all Term Loan Facility first lien collateral including outstanding equity interests of the Borrower and certain of the other subsidiaries of Holdings, in each case, subject to certain limitations; provided, that no ABL Facility first lien collateral or Term Loan Facility first lien collateral owned by the Canadian Borrower secure the obligations owing under the U.S. tranche of the ABL Facility. These accounts receivable and inventory totaled $724.7 million in the aggregate as of March 31, 2018.

As of March 31, 2018, the ABL Borrowers were in compliance with the covenants of the ABL Facility.

Term Loan Facility

The Term Loan Facility provides secured debt financing in an aggregate principal amount of up to $655.0 million and the right, at the Company’s option, to request additional tranches of term loans in an aggregate principal amount, when included with any incremental borrowings issued under the ABL Facility, of up to $175.0 million, plus unlimited additional amounts such that the aggregate principal amount of indebtedness outstanding at the time of incurrence does not cause the Secured Net Leverage Ratio, calculated on a pro forma basis, to exceed 4.1 to 1.0. Availability of such additional tranches of term loans is subject to the absence of any default and, among other things, the receipt of commitments by existing or additional financial institutions.

On December 19, 2017, the Company completed TLB Amendment No. 2 amending the Term Loan Facility. TLB Amendment No. 2 reduced the interest rate margin applicable to outstanding term loans by 50 basis points from 3.75% to 3.25% for LIBOR loans and from 2.75% to 2.25% for base rate loans. TLB Amendment No. 2 also provides for a soft call premium equal to 1% of the amount of the term loans that are subject to certain repricing transactions occurring on or prior to twelve months from the effective date of TLB Amendment No. 2. As a result of TLB Amendment No. 2, the Company paid debt issuance costs of $0.8 million, which will be amortized throughout the remaining life of the Term Loan Facility.

The Company is required to make scheduled quarterly payments in an aggregate annual amount equal to 1.0% of the aggregate principal amount of the outstanding term loans as of the Closing Date of the TLB Amendment No. 2, with the balance due at maturity. The average interest rate for the Term Loan Facility was 4.89% at March 31, 2018. The Company amortized $0.1 million and $0.2 million of debt discount to interest expense during the three and six months ended March 31, 2018, respectively and $0.1 million and $0.3 million of debt discount to interest expense during the three and six months ended March 31, 2017, respectively. The Term Loan Facility matures on June 9, 2023.

Additionally, the Term Loan Facility requires the Company to make mandatory principal payments on an annual basis, commencing with the fiscal year ending September 30, 2017, if cash flows for the year, as defined in the Term Loan Facility, exceed certain levels specified in the Term Loan Facility. The Company was not required to make such mandatory principal payment for the fiscal year ended September 30, 2017. The Company generally has the right to prepay loans in whole or in part, without incurring any penalties for early payment.

Obligations under the Term Loan Facility are secured by a first priority lien on all Term Loan Facility first lien collateral, including outstanding equity interests of the Borrower and certain of the other subsidiaries of Holdings, and a second priority lien on all ABL Facility first lien collateral, including accounts receivable and inventory of the loan parties under the Term Loan Facility, subject to certain limitations.

As of March 31, 2018, the Company was in compliance with the covenants of the Term Loan Facility.

Debt Issuance Cost Amortization

Amortization expense included in interest expense related to debt issuance costs of the Term Loan Facility was $0.7 million and $1.4 million for the three and six months ended March 31, 2018, respectively, and $0.6 million and $1.1 million for the three and six months ended March 31, 2017, respectively.

Capital Lease Obligations

The capital lease obligation balance of $36.2 million as of March 31, 2018 is primarily associated with the Ryder Lease and the Montgomery Lease. The Ryder Lease obligation excludes decreasing annual interest payments ranging from $0.9 million to $0.1 million, for aggregate interest payments totaling $3.2 million. The Montgomery Lease obligation excludes decreasing annual interest payments ranging from $1.0 million to $0.1 million, for aggregate interest payments of $13.1 million.

8. Derivatives

During the three months ended March 31, 2018, the Company entered into three additional interest rate swap agreements with a combined notional amount of $300.0 million to help mitigate interest rate risk related to the variable rate Term Loan Facility. During the three months ended March 31, 2017, the Company entered into four interest rate swap agreements with a combined notional amount of $300.0 million to help mitigate interest rate risk related to the variable rate Term Loan Facility. The swap agreements expire at various dates from February 2020 through February 2023 and are accounted for as cash flow hedges. Gains or losses resulting from changes in the fair value of the swaps are recorded in other comprehensive income. Gains and losses recorded in other comprehensive income are reclassified into and recognized in income when the interest expense on the Term Loan Facility is recognized.

Derivative assets and liabilities at March 31, 2018 and September 30, 2017 consisted of the following:

	Recorded to	March 31, 2018		September 30, 2017
Short-term derivative asset	Other current assets	$	1.1	$	—
Long-term derivative asset	Other non-current assets	$	4.7	$	0.3
Short-term derivative liability	Accrued expenses and other liabilities	$	0.9	$	1.1
Long-term derivative liability(1)	Other non-current liabilities	$	—	$	0.2
Other Comprehensive Income(2)	Accumulated other comprehensive income	$	4.1	$	—

⁽¹⁾ Long-term derivative liability at March 31, 2018 was less than $0.1 million.

⁽²⁾ Other Comprehensive Income for the fiscal year ended September 30, 2017 was less than $0.1 million

Gains and losses (net of reclassifications into income, including any ineffective portion) related to the interest rate swaps were as follows:

		Three Months Ended March 31,				Six Months Ended March 31,
	Recorded to	2018		2017		2018		2017
Realized loss	Interest expense	$	0.3	$	0.3	$	0.7	$	0.3
Unrealized gain, net of tax	Other comprehensive income	$	2.2	$	0.3	$	4.1	$	0.3

Unrealized gains related to the interest-rate swaps for the three and six months ended March 31, 2018 were net of a tax impact of $1.6 million. At March 31, 2018, $0.6 million in unrealized gains were expected to be realized and recognized in income within the next twelve months.

See Note 9 for additional information on the Company’s fair value of the derivative instruments.

9. 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—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.

Fair value of financial instruments

The carrying values of cash and cash equivalents, accounts and notes receivable, accounts payable and short-term borrowings approximate their fair value due to the short-term maturity of those instruments.

The carrying values of borrowings outstanding under the Credit Facilities approximate fair value at March 31, 2018 and September 30, 2017, 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 due to the varying interest rate parameters as outlined in the respective loan agreements.

Assets and Liabilities Measured at Fair Value on a Non-Recurring 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 non-recurring basis as required by U.S. GAAP. Generally, assets are recorded at fair value on a non-recurring basis as a result of impairment charges or as part of a business combination. As discussed in Note 3, during the fiscal year ended September 30, 2017, the Company recorded non-recurring fair value measurements related to the Ultra Chem Acquisition and its asset acquisitions. These fair value measurements were classified as Level 3 within the fair value hierarchy.

25

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Contingent Consideration

The fair value of the contingent consideration related to the Deferred Cash Consideration as discussed in Note 4 was $54.2 million and $35.1 million as of March 31, 2018 and September 30, 2017, respectively. The increase in the liability was largely driven by the increase in the Company’s stock price. The measurement of the contingent consideration related to the Deferred Cash Consideration is classified by the Company as a Level 3 measurement within the fair value hierarchy. In order to estimate the fair value of the Deferred Cash Consideration, the Company estimates the value of the Excess Shares using a Monte Carlo simulation model with the market price of the Company’s common stock at each valuation date being a significant input to this model. Unobservable inputs to the valuation are the expected volatility during the applicable period as well as a marketability discount to reflect the illiquidity of the Excess Shares given their terms. An increase in the market price of the Company’s common stock has the same directional effect on the value of the liability related to the Deferred Cash Consideration. An increase in the volatility and marketability discount will lower the value of the liability related to the Deferred Cash Consideration.

The fair value of the liability for the contingent consideration related to the TRA as discussed in Note 4 was $75.8 million and $105.1 million as of March 31, 2018 and September 30, 2017, respectively. The decrease in the liability is reflective of the provisional impact associated with the Tax Act enacted in December 2017 (see Note 15), which lowers the Company’s projected income tax liabilities, the estimate of tax benefits expected to be realized as a result of the Business Combination and the ultimate amount expected to be paid by the Company to the Selling Equityholders. The liability for the contingent consideration related to the TRA is classified by the Company as a Level 3 measurement within the fair value hierarchy. The Company estimates the fair value of the liability for the contingent consideration related to the TRA based on a discounted cash flow model which incorporates assumptions of projected taxable income, projected income tax liabilities and an estimate of tax benefits expected to be realized as a result of the Business Combination. Key inputs to the valuation are prevailing tax rates and market interest rates impacting the discount rate. A 100 basis point increase in the discount rate compared to the discount rate used at the March 31, 2018 valuation would have resulted in a decrease of approximately $0.3 million in the value of the liability for the contingent consideration related to the TRA. Additionally, this cash flow model is sensitive to changes in prevailing tax rates. A 100 basis point increase in the tax rate compared to the tax rate used at the March 31, 2018 valuation would have resulted in an increase of approximately $2.4 million in the value of the liability for the contingent consideration related to the TRA.

Changes in the fair value of the contingent consideration obligations for the six months endedMarch 31, 2018 were as follows:

	TRA			Deferred Cash Consideration		Total Fair Value
Contingent consideration as of September 30, 2017	$	105.1		$	35.1	$	140.2
Cash paid to TPG	(4.2		)	—		(4.2		)
Change in fair value of contingent consideration(1)	(25.1		)	19.1		(6.0		)
Contingent consideration as of March 31, 2018	$	75.8		$	54.2	$	130.0

⁽¹⁾Included in Operating income in the condensed consolidated statements of operations.

Significant changes in the estimates and inputs used in determining the fair value of the contingent consideration could have a material impact on the amounts recognized as a component of Operating income in future periods.

Interest Rate Swaps

The Company classifies interest rate swaps within Level 2. During the three months ended March 31, 2018, the Company entered into three additional interest rate swap agreements to help mitigate interest rate risk related to the variable rate Term Loan Facility. During the three months ended March 31, 2017, the Company entered into four interest rate swap agreements to help mitigate interest rate risk related to the variable rate Term Loan Facility. The swap agreements expire at various dates through February 2023. At March 31, 2018, the Company recorded $1.1 million to Othercurrentassets, $4.7 million in Other non-current assets and$0.9 million in Accrued expenses and other liabilities in the condensed consolidated balance sheets related to these instruments.

26

During the six months endedMarch 31, 2018 and 2017, the Company did not have any transfers between Level 1, Level 2 or Level 3 fair value measurements.

10. Share-based Compensation and Employee Benefit Plans

On June 8, 2016, the Company’s stockholders approved the 2016 LTIP, with an effective date of March 30, 2016, covering approximately a ten-year period. No awards may be granted under the 2016 LTIP after March 20, 2026. The 2016 LTIP permits the grant of up to 9,000,000 shares of the Company's common stock for various types of awards to employees, directors and consultants of the Company or its subsidiaries, including incentive and non-incentive stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalents, stock awards, conversion awards and performance awards.

During the six months endedMarch 31, 2018, the Company granted 193,667 PSUs to employees under the 2016 LTIP. These awards will vest on September 30, 2020, entitling the recipient to receive a certain number of shares of the Company’s common stock, based on the Company’s achievement of the performance goals included in the PSUs, which are based on a return on invested capital calculation over a three-year performance period. Depending on the calculation as of the vesting date, a recipient is entitled to receive between 0% and 200% of the initial award. The awards are accounted for as equity instruments, and the fair value of these awards was determined by the closing price of the Company's common stock on the date of grant.

During the fiscal years ended September 30, 2017 and 2016, the Company granted 212,000 and 1,557,500 PSU awards to employees, respectively, under the 2016 LTIP. The recipient can receive between 0% and 200% of the initial award, based on the Company’s total stockholder return during approximate three-year performance period, or a cumulative Adjusted EBITDA target if a specified total stockholder return is not met. The Company used the Monte Carlo simulation model to estimate the fair value of the PSU awards at the grant date, factoring in the market-based vesting condition and considering the probability of satisfying the various performance criteria. The resulting grant date fair value is recognized as expense on a straight-line basis from the grant date through the end of the performance period. The assumptions used in the Monte Carlo simulation model for PSUs included an expected stock price volatility between 35% and 40% based on a peer group of similar companies, an expected dividend yield of 0%, an expected term of two to three years, and a risk-free interest rate of between 0.9% and 1.3%.

The following table summarizes all PSU activity during the six months endedMarch 31, 2018:

	PSUs		Average Grant Date Fair Value Per Unit
Unvested PSUs at September 30, 2017	1,524,000		$	8.92
Granted	193,667		7.50
Vested	—		—
Forfeited/Canceled	(22,500	)	9.13
Unvested PSUs at March 31, 2018	1,695,167		$	8.76

As of March 31, 2018, the Company may issue up to 3,390,334 shares of common stock related to the outstanding PSU awards described above under the 2016 LTIP. The PSU awards are accounted for as equity instruments, and the Company recognized compensation cost of $1.1 million and $2.3 million as a component of Selling, general and administrative expenses on the condensed consolidated statements of operations for the three and six months ended March 31, 2018, respectively, and $1.1 million and $2.2 million for the three and six months ended March 31, 2017, respectively, related to the PSUs. As of March 31, 2018, the outstanding PSUs had a weighted-average remaining contract life of 1.4 years. As of March 31, 2018, there was $6.5 million of total unrecognized compensation cost related to unvested PSUs.

27

In November 2017, the Company granted 415,867 shares of restricted stock to employees under the 2016 LTIP. The restricted stock awards vest equally on the anniversary of the grant date over a three-year period provided that the recipients of such grants continue their employment with the Company. The awards are accounted for as equity instruments, and the fair value of the restricted stock awards was determined by the closing price of the Company's common stock on the date of grant. During the fiscal years ended September 30, 2017 and 2016, the Company granted restricted stock awards to certain of the Company’s non-employee directors under the 2016 LTIP that vest one year from the date of grant.

The following table summarizes all restricted stock activity during the six months endedMarch 31, 2018:

	Shares of Restricted Stock		Average Grant Date Fair Value Per Unit
Restricted stock at September 30, 2017	77,458		$	8.26
Granted	415,867		7.50
Vested	—		—
Forfeited/Canceled	(24,008	)	8.20
Restricted stock at March 31, 2018	469,317		$	7.59

The restricted stock awards are accounted for as equity instruments, and the Company recognized compensation expense of $0.4 million and $0.7 million as a component of Selling, general and administrative expenses on the condensed consolidated statements of operations during the three and six months ended March 31, 2018, respectively, and $0.1 million and $0.3 million during the three and six months ended March 31, 2017, respectively, related to the restricted stock. As of March 31, 2018, there was $2.7 million of total unrecognized compensation expense related to restricted stock, and a weighted average remaining life of 2.3 years.

During the fiscal year ended September 30, 2016, the TPG Restricted Stock Grants were awarded with respect to 100,000 shares of Company common stock owned by TPG. These awards vest in equal amounts over a three-year period provided that the recipients of such grants continue their employment with the Company. During the six months ended March 31, 2018, 11,673 shares were transferred back to TPG due to forfeiture. During the fiscal year ended September 30, 2017, 33,333 shares of these awards vested and 9,576 shares were transferred to the Company (reflected as treasury stock) to satisfy the officers’ and employees’ tax withholding obligations in connection with the vesting. The Company recognized compensation cost of less than $0.1 million and $0.1 million as a component of Selling, general and administrative expenses on the condensed consolidated statements of operations for the three and six months ended March 31, 2018, respectively, and $0.1 million and $0.2 million for the three and six months ended March 31, 2017, respectively, related to these awards. As of March 31, 2018, there was $0.4 million of total unrecognized compensation cost related to these awards and a weighted average remaining life of 1.2 years. While these awards were not made pursuant to the 2016 LTIP, they constitute equity-based compensation and therefore will count against the 2016 LTIP's share reserve to the extent the awards vest.

During the six months endedMarch 31, 2018, the Company granted 999,492 stock options to employees under the 2016 LTIP. The awards vest in equal amounts over a three-year period provided that the recipients of such grants continue their employment with the Company. The Company used the Black-Scholes Merton model to estimate the fair value of the option awards at the grant date. The resulting grant date fair value is recognized as expense on a straight-line basis over the vesting period. The assumptions used in the Black-Scholes Merton model for the options included an expected term of six years, an expected stock price volatility of 35.0% based on a peer group of similar companies, an expected dividend yield of 0.0% and a risk-free interest rate of 2.1%.

The following table summarizes stock option activity during the six months endedMarch 31, 2018:

	Stock Options	Average Grant Date Fair Value Per Unit		Weighted Average Exercise Price
Stock Options at September 30, 2017	—	$	—	$	—
Granted	999,492	2.84		7.42
Exercised	—	—		—
Forfeited/Canceled	—	—		—
Stock Options at March 31, 2018	999,492	$	2.84	$	7.42

The stock options are accounted for as equity instruments, and the Company recognized compensation expense of $0.3 million and $0.4 million as a component of Selling, general and administrative expenses on the condensed consolidated statements of operations during the three and six months ended March 31, 2018, respectively, related to the restricted stock. As of March 31, 2018, there was $2.3 million of total unrecognized compensation expense related to stock options, and a weighted average remaining contractual life of 9.6 years. The outstanding stock options as of March 31, 2018 had an aggregate intrinsic value of $3.3 million. No stock options were exercisable as of March 31, 2018.

During the three months ended December 31, 2016, the Company granted certain employees a total of 28,000 RSUs under the 2016 LTIP that vest equally over a three-year period on the anniversary of the grant date provided the employee remains employed by the Company. Upon vesting, the recipients will receive a share of common stock in the Company for each RSU awarded. The fair value of these RSUs was determined based on the closing price of the Company’s stock on the grant date.

The following table summarizes RSU award activity during the six months endedMarch 31, 2018:

	RSUs		Average Grant Date Fair Value Per Unit
Unvested RSUs at September 30, 2017	24,500		$	7.28
Granted	—		—
Vested	(8,162	)	7.28
Forfeited/Canceled	—		—
Unvested RSUs at March 31, 2018	16,338		$	7.28

The RSUs are accounted for as equity instruments, and the Company recognized compensation cost of less than $0.1 million as a component of Selling, general and administrative expenses on the condensed consolidated statements of operations during the three and six months ended March 31, 2018 and 2017 related to the RSUs. During the six months ended March 31, 2018, 8,162 RSUs vested, and 2,777 shares were transferred to the Company (reflected as treasury stock) to satisfy the employees’ tax withholding obligations in connection with the vesting. As of March 31, 2018, there was $0.1 million of total unrecognized compensation cost related to the RSUs, and a weighted average remaining life of 1.6 years.

During the three months ended December 31, 2016, the Company also awarded 10,500 phantom RSUs and 10,000 phantom PSUs to certain non-U.S. employees under the 2016 LTIP. The phantom RSUs vest equally over a three-year period on the anniversary of the grant date while the phantom PSUs vest under the same conditions as the PSU awards described above. During the fiscal year ended September 30, 2017, 3,500 of the phantom RSUs were forfeited and all of the phantom PSUs were forfeited. Upon vesting and provided the employee remains employed by the Company at that time, the awards will be settled in cash. In accordance with ASC 718, the remaining phantom RSU awards are accounted for as a liability, with the awards re-measured at the end of each reporting period based on the closing price of the Company’s common stock or using a Monte Carlo simulation model, as applicable. Compensation expense is recognized ratably on a straight-line basis over the requisite service period. An immaterial amount of compensation expense was recognized during the three and six months ended March 31, 2018 and 2017 related to these awards.

As of March 31, 2018, there were 3,967,265 shares of the Company’s common stock available for issuance under the 2016 LTIP, assuming the PSU awards vest at their maximum target.

Dilutive computations during the current period contain additional incremental common shares which are attributable to the outstanding unvested restricted stock awards issued to directors and employees and restricted stock units awards to employees; the outstanding stock options were not included as the result would have been anti-dilutive. During the three and six months ended March 31, 2017, the outstanding restricted stock awards and restricted stock unit awards were not included as their impact on the Company’s net loss would have been anti-dilutive. For the three and six months ended March 31, 2018 and 2017, there were 12,476,250 Founder Shares excluded from the basic and diluted computations because such shares were subject to forfeiture, and PSU awards, which were not included in the computation of diluted shares outstanding because performance targets and/or market conditions were not yet met for these awards. Diluted shares outstanding also did not include 25,012,500 shares of common stock issuable on the exercise of 50,025,000 warrants because the warrants were out-of-the-money for the three and six months ended March 31, 2018 and 2017.

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, handling, transportation and disposal of chemicals and hazardous materials. These laws pertain to air and water, the management of solid and hazardous wastes, transportation and human health and safety.

On March 31, 2011, the Predecessor 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 ("the 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 received notice prior to the fifth anniversary of the closing (the "Other Retained Remediation Liabilities") (collectively, the "Retained Remediation Liabilities").  Ashland’s liability for the 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. Had the Predecessor incurred expenses arising out of the Other Retained Remediation Liabilities, Ashland’s indemnification obligation would have been subject to an individual claim threshold of $0.2 million and an aggregate claim deductible of $5.0 million. Ashland’s indemnification obligations under the ADA

32

Purchase Agreement as described above terminated as of March 31, 2016, other than for the Retained Remediation Liabilities. 

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 sought a declaration that, pursuant to the ADA Purchase Agreement, Solutions was obligated to indemnify Ashland for losses Ashland incurred pertaining to the Other Retained Remediation Liabilities, up to the amount of the aggregate $5.0 million deductible applicable for expenses incurred by Solutions, whether or not Solutions incurs any expenses or obtained any indemnity from Ashland.  Ashland further alleged that Solutions breached duties related to the ADA Purchase Agreement by not having so indemnified Ashland for amounts Ashland incurred for Other Retained Remediation Liabilities at sites where Ashland disposed of wastes prior to the Ashland Distribution Acquisition, and on that basis sought unspecified compensatory damages, costs and attorney’s fees.  On June 21, 2017, the Company’s Motion for Summary Judgment for this lawsuit was granted. Ashland appealed the ruling on July 20, 2017. On January 31, 2018, the Delaware Supreme Court affirmed the lower court’s grant of the Company’s Motion for Summary Judgment. Ashland did not request a rehearing of the ruling. Therefore, the judgment in the Company’s favor is final and this matter is closed. The Company does not currently have any environmental or remediation reserves for matters covered under the ADA Purchase Agreement.

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 any 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 DTSC that an 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.

14. Related Party Transactions

On February 28, 2018, the Company entered into a Transportation Logistics Management Services Agreement with Transplace Texas, LP (“Transplace”), pursuant to which Transplace, a portfolio company of TPG and affiliate of the Company, agrees to provide certain transportation logistics management services to the Company over a minimum period of three years at an estimated annual cost of $1.2 million. The agreement was entered into on arms’ length terms following a competitive bid process.

The tables below summarize activity recorded during the respective periods for related party transactions:

	Three Months Ended March 31,				Six Months Ended March 31,
	2018		2017		2018		2017
Sales to related entities:
TPG	$	0.9	$	0.8	$	2.5	$	1.5
Purchases from related entities:
Entities related to members of the Board of Directors	$	2.8	$	0.6	$	6.2	$	1.0

33

	March 31, 2018		September 30, 2017
Accounts receivable from related entities:
TPG	$	0.6	$	0.7
Accounts payable to related entities:
Entities related to members of the Board of Directors	$	0.5	$	0.1

Contingent Consideration Obligations Pursuant to the TRA and the Merger Agreement

Subsequent to the Business Combination, TPG beneficially owns approximately 35% of the Company’s common stock, including Founder Shares, and is considered a related party of the Company. In connection with the Business Combination, TPG became a party to the TRA and obtained the right to receive the Deferred Cash Consideration pursuant to the Merger Agreement. The fair value of these contingent consideration liabilities was as follows:

	March 31, 2018		September 30, 2017
Due to related party pursuant to contingent consideration obligations:
Current liability	$	8.8	$	12.5
Non-current liability	121.2		127.7
Total fair value	$	130.0	$	140.2

During the six months endedMarch 31, 2018 the Company paid $4.2 million to TPG related to the TRA. See Note 9.

15. Income Taxes

For all periods, the Company computed the provision for income taxes based on the actual year-to-date effective tax rate by applying the discrete method.  Use of 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.

The Tax Act significantly revises future U.S. corporate income taxes by, among other things, lowering U.S. corporate income tax rates and implementing a modified territorial tax system. Because the Company has a September 30 fiscal year end, the lower corporate income tax rate will be phased in, resulting in a U.S. statutory federal rate of approximately 24.3% for the Company’s fiscal year ending September 30, 2018 and 21.0% for subsequent fiscal years. The Tax Act also provided for certain transition impacts. As part of the transition to the new modified territorial tax system, the Tax Act imposes a one-time repatriation tax on deemed repatriation of historical earnings of foreign subsidiaries. The Company does not currently anticipate an impact from the repatriation tax charge.

For the six months ended March 31, 2018, the impact of the Tax Act resulted in a net tax benefit of approximately $4.5 million, related solely to the remeasurement of the Company’s net deferred tax liabilities at the lower enacted corporate tax rates.

In accordance with recently issued SEC guidance, the estimated net income tax benefit of $4.5 million is considered provisional representing the Company’s current best estimate based on interpretation of the provisions of the Tax Act, as data continues to be accumulated in order to finalize the underlying calculations. In addition, due to the broad and complex changes contained in the Tax Act, the Company’s current estimate of the impact may be influenced by, among other things, changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act and any changes in accounting standards for income taxes or related interpretations issued in response to the Tax Act. The Company anticipates finalizing and recording any resulting adjustments by the end of its current fiscal year ending September 30, 2018.

34

Income tax expense for the three months ended March 31, 2018 was $4.6 million on pre-tax income of $5.0 million compared to the income tax expense of $0.8 million on pre-tax loss of $0.3 million for the three months ended March 31, 2017. The current and prior period tax expense was largely attributable to income in profitable foreign jurisdictions.

Income tax expense for the six months ended March 31, 2018 was $5.9 million on pre-tax income of $32.8 million compared to the income tax benefit of $1.9 million on pre-tax loss of $11.3 million for the six months ended March 31, 2017. The current period tax expense was largely attributable to current year income. The expense generated in the U.S. was offset by a current period benefit on deferred tax liabilities as a result of the impact of the Tax Act. The prior period tax benefit was largely attributed to U.S. operations related to deferred taxes driven by the net loss incurred during the period.

At March 31, 2018 and September 30, 2017, the valuation allowance was $2.6 million and $3.1 million, respectively, primarily related to operations in Asia. 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, 2018, management believes it is more likely than not that it will realize the majority of its deferred tax assets.

Uncertain Tax Positions

In connection with the Ultra Chem Acquisition, the Company recorded income tax-related uncertainties totaling $1.4 million, inclusive of interest and penalties. Additionally, the Company also recognized indemnification assets related to certain of these income tax-related uncertainties. The indemnification assets were included in Other current assets and Other non-current assets in the condensed consolidated balance sheets, representing the reimbursement the Company reasonably expected to receive from funds held in escrow pursuant to the purchase agreement.  See Note 3.

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 all periods. The Company had $1.5 million and $1.8 million related to uncertain tax positions, including related accrued interest and penalties as of March 31, 2018 and September 30, 2017, respectively. Between the time of the initial recording of the uncertain tax provisions associated with the Ultra Chem Acquisition and the three months ended March 31, 2018, the Company reduced the reserve by approximately $0.4 million due to the lapse of the applicable statute of limitations.

16. Segment and Geographic Data

The Company operates through three lines of business, or operating segments: Chemicals, Plastics and Environmental Services, which market to different sets of customers operating in an array of industries, with various end markets and customer segments within those industries. For segment presentation and disclosure purposes, the Chemicals and Plastics lines of business constitute separate reportable segments, while the Environmental Services line of business, which does not meet the materiality threshold for separate disclosure, is included 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.

35

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 services and supply, technical support, price and delivery capabilities. 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 and Plastics lines of business are distribution businesses, while the Environmental Services line of business provides hazardous and non-hazardous waste collection, recovery, recycling and disposal services.

A brief description of each segment follows:

Chemicals. The Chemicals line of business distributes specialty and industrial chemicals, additives and solvents to industrial users via railcars, barges, bulk tanker trucks and as packaged goods in trucks. The Company’s chemical products are distributed in more than 50 countries worldwide, primarily in North America and Asia. In connection with the distribution of chemicals products, the Company provides value-added services such as custom blending, packaging and re-packaging, private-label manufacturing and product testing in the form of chemical analysis, product performance analysis and product development. While the Chemicals line of business serves multiple end markets, key end markets within the industrial space are household, industrial and institutional, performance coatings (including architectural coatings, adhesives, sealants and elastomers), lubricants, oil and gas and personal care.

Plastics. The Plastics line of business distributes a broad product line consisting of commodity polymer products and prime engineering resins to plastics processors engaged in blow molding, extrusion, injection molding and rotation molding via railcars, bulk trucks, truckload boxes and mixed truckloads or less-than-truckload quantities. The Company's plastics products are distributed in more than 50 countries worldwide, primarily in North America, EMEA and Asia. While the Plastics line of business serves a broad cross section of industrial segments; key end markets are automotive and healthcare.

Other. The Environmental Services line of business, in connection with certain waste disposal service companies, provides customers with comprehensive on-site and off-site hazardous and non-hazardous waste collection, transportation, recovery, disposal arrangement, and recycling 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 and through a staff of dedicated on-site waste professionals. The Environmental Services line of business serves multiple end markets such as aerospace and defense, automotive, chemical manufacturing, industrial manufacturing and oil and gas.

The Chief Executive Officer is the Chief Operating Decision Maker. The Chief Operating Decision Maker reviews operating results 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 Chief Operating Decision Maker in evaluating line of business performance. These expenses include depreciation and amortization, selling, general and administrative expense and corporate items including 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% of revenues for any line of business for each of the periods reported. Intersegment revenues were insignificant.

Certain assets are aggregated at the line of business level. The assets attributable to the Company’s lines of business, that are reviewed by the Chief Operating Decision Maker, 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, as well as property, plant and equipment, are generally not allocated to a line of business and are included in unallocated assets.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the Company’s financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and with the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2017 filed with the SEC on December 7, 2017. This discussion contains forward-looking statements reflecting our current expectations, estimates and assumptions concerning events and financial trends that may affect our future operating results or financial position. Actual results and the timing of events may differ materially from those contained in these forward-looking statements due to a number of factors, including those discussed in the sections entitled “Risk Factors” and “Forward-Looking Statements” elsewhere in this Quarterly Report on Form 10-Q. 

The terms “the Company,” “us,” “our,” “we” and similar terms in this report refer to Nexeo Solutions, Inc. and its consolidated subsidiaries.

Overview

We are a global chemicals distributor in North America and Asia and a global plastics distributor in North America, EMEA and Asia. In connection with the distribution of chemicals products, we provide value-added services such as custom blending, packaging and re-packaging, private-label manufacturing and product testing in the form of chemical analysis, product performance analysis and product development. We also provide on-site and off-site hazardous and non-hazardous environmental services, including waste collection, transportation, recovery, disposal arrangement and recycling services in North America, primarily in the U.S.

We have long-standing relationships with major chemicals and plastics producers and suppliers, a strong geographic presence and supply chain network and a balanced customer base that benefits from the service and distribution value we provide. The products we distribute are used in various end markets and customer segments within a broad cross section of manufacturing industries, including household, industrial and institutional, lubricants, performance coatings (including architectural coatings, adhesives, sealants and elastomers), automotive, healthcare, personal care, oil and gas and construction end markets.

We distribute our product portfolio through a global supply chain consisting of owned, leased or third-party warehouses, rail terminals and tank terminals. We have a private fleet of tractors and trailers, primarily in North America.

Segment Overview

We operate through three lines of business, or operating segments: Chemicals, Plastics and Environmental Services. Our lines of business market to different sets of customers operating in an array of different industries, with various end markets and customer segments within those industries. For segment presentation and disclosure purposes, our Chemicals and Plastics lines of business constitute separate reportable segments, while our Environmental Services line of business, which does not meet the materiality threshold for separate disclosure, is included in an "Other" category.

A brief description of each of our lines of business follows:

Chemicals. Our Chemicals line of business distributes specialty and industrial chemicals, additives and solvents to industrial users via railcars, barges, bulk tanker trucks and as packaged goods in trucks. Our chemicals products are distributed in more than 50 countries worldwide, primarily in North America and Asia. In connection with the distribution of chemicals products, we provide value-added services such as custom blending, packaging and re-packaging, private-label manufacturing and product testing in the form of chemical analysis, product performance analysis and product development. While our Chemicals line of business serves multiple end markets, the key end markets within the industrial space are household, industrial and institutional, performance coatings (including architectural coatings, adhesives, sealants and elastomers), lubricants, oil and gas and personal care.

38

Plastics. Our Plastics line of business distributes a broad product line consisting of commodity polymer products and prime engineering resins to plastics processors engaged in blow molding, extrusion, injection molding and rotation molding via railcars, bulk trucks, truckload boxes and mixed truckloads or less-than-truckload quantities. We distribute plastics products in more than 50 countries worldwide, primarily in North America, EMEA and Asia. Our Plastics line of business serves a broad cross section of industrial segments; key end markets are automotive and healthcare.

Other. Our Environmental Services line of business, in connection with certain waste disposal service companies, provides customers with comprehensive on-site and off-site hazardous and non-hazardous waste collection, transportation, recovery, disposal arrangement, and recycling services in North America, primarily in the U.S. These environmental services are offered through our network of distribution facilities used as transfer facilities and through a staff of dedicated on-site waste professionals. Our Environmental Services line of business serves multiple end markets such as aerospace and defense, automotive, chemical manufacturing, industrial manufacturing and oil and gas.

Key Factors Affecting our Results of Operations and Financial Condition

General and regional economic conditions. Consumption of chemicals and plastics in the industries and markets we serve are generally affected by the global economy and amplified by regional conditions. Although we manage our cost structure in line with general economic conditions, our volumes and profitability are ultimately correlated with the underlying demand for the end-products of the industries we serve. The first half of fiscal year 2018 experienced an improvement in industrial market demand.

Price fluctuations. Selling prices of the products we distribute within our Chemicals and Plastics lines of business fluctuate with changes in the prices we pay for products.  Product costs are largely driven by global and regional economic conditions affecting the prices of two primary raw materials of production: crude oil (primarily naphtha) and natural gas (primarily ethane).  These two raw materials are used in the production of propylene and ethylene, the key feedstocks used in over 90% of organic-based commodity and specialty chemicals, as well as in the subsequent production of the intermediate plastics products we distribute.  The prices of these feedstocks are also affected by other factors, including choices made by producers for uses of feedstocks (e.g., as an ingredient in gasoline versus a feedstock to the chemical industry) and the capacity devoted to production and other macroeconomic factors that impact the producers.  As a distributor, the prices of these feedstocks are not in our control.  We are generally able to adjust finished good prices in accordance with the fluctuations in our product costs and transportation-related costs (e.g., fuel costs).  As a result, movements in our sales revenue and cost of sales tend to correspond with changes in our product prices.  Through the first half of fiscal year 2018, we continued to execute on effective pricing initiatives and managed supply constraints through efficient inventory management.

As capacity or demand patterns change, there can be a corresponding volatility in the selling prices of the products we distribute.  Gross profit margins generally decrease in deflationary price environments and increase during inflationary pricing environments, although the extent to which profitability increases or decreases depends on the rate at which selling prices adjust relative to inventory costs.  As a logistics provider, oil prices affect our transportation and delivery costs, along with changes in driver regulations, supply of drivers and common carrier rates.

Volume-based pricing. We generally procure chemicals and plastics raw materials through purchase orders rather than under long-term contracts with firm commitments. Our arrangements with key producers and suppliers are typically embodied in agreements that we refer to as framework supply agreements. We work to develop strong relationships with a select group of producers and suppliers that complement our strategy based on a number of factors, including price, breadth of product offering, quality, market recognition, delivery terms and schedules, continuity of supply and each producer’s strategic positioning. Our framework supply agreements with producers and suppliers typically renew annually and, while they generally do not provide for specific product pricing, some, primarily those related to our Chemicals line of business, include volume-based financial incentives through supplier rebates, which we earn by meeting or exceeding target purchase volumes.

39

Inflation. Our average selling prices generally rise in inflationary price environments as producers and suppliers raise the market prices of the products that we distribute. During inflationary periods our customers maximize the amount of inventory they carry in anticipation of even higher prices. Consequently, this environment of excess demand favorably impacts our volumes sold, revenues and gross profit due to the lag between rising prices and our cost of goods sold. The reverse is true in deflationary price environments. Deflationary forces create an environment of overcapacity, driving market prices of products downward, and we must quickly adjust inventories and buying patterns to respond to price declines. Our primary objective is to replace inventories at lower costs while maintaining or enhancing unit profitability.

Some of our assets and liabilities, primarily cash, receivables, inventories and accounts payable, are impacted by commodity price inflation because they are indirectly affected by market prices of the raw materials that are used to manufacture our products. 

Currency exchange rate fluctuations. We conduct our business on an international basis, in multiple currencies.  A portion of our sales and costs of sales transactions are denominated in currencies other than the functional currency of our subsidiaries.  Further, we have exposure to foreign exchange fluctuations arising from the remeasurement of certain foreign operations where the USD is the functional currency but accounting records are maintained in local currency. Strengthening/weakening of our subsidiaries’ functional currency relative to the other currencies in which some transactions are denominated or recorded creates foreign currency gains/losses, which we include in Selling, general and administrative expenses. Additionally, we report our consolidated results in USD and the results of operations and the financial position of our local international operations are translated into USD at the applicable exchange rates for inclusion in our condensed consolidated financial statements.  Strengthening of the USD relative to our subsidiaries’ functional currencies causes a negative impact on sales but a positive impact on costs.

Outlook

General. We have operations in North America, EMEA and Asia and are subject to broad, global and regional macroeconomic factors. These factors include:

• the general state of the economy, specifically inflationary or deflationary trends, GDP growth rates and commodity/feedstock price movements;

• unemployment levels;

• government regulation and geopolitical changes;

• fiscal and monetary policies of governments, including import and export tariffs, duties and other taxes;

• general income growth and the consumption rates of products;

• increases in transportation related costs and changes in our relationship with common carriers; and

• technological change in the industries we serve.

We monitor these factors routinely for both strategic and operational impacts.

Our operations are most impacted by regional market price fluctuations of the primary feedstock materials, including crude oil and natural gas, and the downstream derivatives of these primary raw materials. Market price fluctuations of these primary raw materials directly impact the decisions of our suppliers, specifically the manufacturing capacity made available for production of the products we distribute. As capacity or demand patterns change, we may experience a corresponding change in the average selling prices of the products we distribute.

The global markets showed growth during the first half of fiscal year 2018 reflected by increases in GDP, oil prices and U.S. Industrial Production Index.

The following is a summary of GDP, oil price and U.S. Industrial Production Index fluctuations in our various regions of operations by fiscal quarter:

	Q2 18 v Q2 17		Q1 18 v Q1 17		Q4 17 v Q4 16		Q3 17 v Q3 16
North America
U.S. GDP Growth	2.9	%	2.6	%	2.3	%	2.2	%
U.S. Industrial Production Index	3.9	%	3.0	%	1.3	%	1.9	%
West Texas Intermediate Crude Oil Average Price Increase	21.5	%	12.2	%	7.2	%	5.5	%
EMEA
Euro Area GDP Growth	2.5	%	2.8	%	2.7	%	2.4	%
Brent Crude Oil Average Price Increase	23.1	%	20.3	%	11.0	%	8.0	%
Asia
China GDP Growth (1)	6.8	%	6.9	%	6.9	%	6.9	%

⁽¹⁾ As reported by the Chinese government.

Overall GDP growth has increased in many of the countries in which we operate. As a result we have experienced an increase in sales volumes. In terms of currency, the USD has weakened over the prior comparable period against most other currencies in which we transact. As a result of these factors, reported dollar revenues and gross profit have been positively impacted in many of our regional operations.

North America

The North American economic environment continued to improve during the first half of fiscal year 2018. U.S. GDP increased in the second fiscal quarter of 2018 as compared to second fiscal quarter of 2017, and the inflation rate rose 2.4% in the second fiscal quarter of 2018 compared to the same period in the prior year.

In terms of currency, the CAD strengthened when compared against the USD for the first half of fiscal year 2018 following declines during fiscal year 2017, which positively affected, among other items, the reported dollar revenues and gross profit from our operations in Canada. Additionally, the Peso strengthened in value against the USD in the first half of fiscal year 2018.

EMEA

In Europe, we conduct business primarily in the Western European countries. As evidenced by their increases in GDP, the economic environment in the countries in which we operate in Europe has continued to improve.

In terms of currency, the euro and other European currencies strengthened versus the USD in the first half of fiscal year 2018, which positively affected, among other items, the reported dollar revenues and gross profit from our European operations.

The market price for the products we sell in Europe typically correlate to the market price of Brent Crude as these operations are primarily based on the distribution of commodity plastics products which are sourced in Europe. Consistent with the increase in oil prices through fiscal year 2017 and the first half of fiscal year 2018, we have experienced an increase in average selling price for the products we distribute in Europe.

Asia

Our operations in Asia are concentrated mainly in China. GDP growth in China, as reported by the Chinese government, has remained steady through the past several fiscal quarters.

In terms of currency, the RMB strengthened against the USD during the first half of fiscal year 2018 following declines during fiscal year 2017, which positively affected, among other items, the reported dollar revenues and gross profit from our operations in China.

Sales and operating revenues

Sales and operating revenues for the three months ended March 31, 2018increased$123.3 million, or 13.4%, compared to the three months ended March 31, 2017. Excluding $19.8 million in revenues from the Ultra Chem Group, or 1.9%, the increase in revenues was primarily attributable to an increase in average selling prices of 11.7% across all segments in all regions. Approximately $25.0 million of the increase was a result of strengthening exchange rates of various currencies versus the USD as compared to the same period in the prior fiscal year.

Chemicals

Sales and operating revenues for the Chemicals line of business for the three months ended March 31, 2018increased$72.8 million, or 17.5%, compared to the three months ended March 31, 2017. Excluding $19.8 million in revenues from the Ultra Chem Group, the revenue increase was primarily attributable to a 10.2% increase in average selling prices and an increase in volumes of 2.3% across multiple product lines. Volume and average selling price performance was a result of continued expansion of our specialty business and recovery in the oil and gas industry, partially offset by volume decreases in Asia.

42

Plastics

Sales and operating revenues for the Plastics line of business for the three months ended March 31, 2018increased$45.2 million, or 9.6%, compared to the three months ended March 31, 2017. The revenue increase was primarily attributable to a 14.1% increase in average selling prices resulting from improved product mix in North America and continued market share gain in EMEA. Overall, volumes were down 4.0% compared to the three months ended March 31, 2017 resulting from the commercial decision to terminate low margin and unprofitable business in North America and Asia. Approximately $23.5 million of the increase was a result of strengthening exchange rates of various currencies versus the USD compared to the same period in the prior fiscal year.

Other

Sales and operating revenues for the Other segment for the three months ended March 31, 2018increased$5.3 million, or 17.1%, compared to the three months ended March 31, 2017. The increase in revenues was primarily due to growth in service offerings to existing customers.

Gross profit

Gross profit increased$13.5 million, or 13.2%, for the three months ended March 31, 2018 compared to the three months ended March 31, 2017. Our centralized platform allowed us to effectively manage supply constraints affecting various product lines. Additionally, our specialty mix increased in both the Chemicals and Plastics lines of business. Approximately $2.2 million of the increase in gross profit was due to the strengthening of exchange rates of various currencies versus the USD compared to the same period in the prior fiscal year.

Chemicals

Gross profit for the Chemicals line of business increased$11.4 million, or 22.5%, for the three months ended March 31, 2018 compared to the three months ended March 31, 2017. Gross profit increased due to our strong commercial execution strengthened by leveraging our centralized technology platform to effectively manage supply shortages for certain specialty products globally as well as supply constraints in North America predominately caused by adverse weather conditions during the quarter.

Plastics

Gross profit for the Plastics line of business increased$1.2 million, or 2.6%, for the three months ended March 31, 2018 compared to the three months ended March 31, 2017. The increase is due to approximately $2.1 million in gross profit due to the strengthening of exchange rates of various currencies versus the USD compared to the same period in the prior fiscal year, partially offset by volume declines as discussed above. However, in North America, we continued to leverage our centralized platform to effectively manage pricing due to supply constraints and volume declines.

Other

Gross profit for the Other segment increased$0.9 million, or 15.5%, for the three months ended March 31, 2018 compared to the three months ended March 31, 2017. The increase was primarily due to certain management cost savings initiatives.

Selling, general and administrative expenses for the three months ended March 31, 2018increased$5.9 million, or 7.4%, compared to the three months ended March 31, 2017. This increase was primarily driven by increased incentive compensation cost of $2.0 million, stock-based compensation cost of $0.5 million and costs of $0.6 million associated with the Ultra Chem Acquisition employee base. Included in selling, general and administrative expenses for the current period were $1.1 million of costs related to the integration of the Ultra Chem Group into our ERP system. Additionally, depreciation and amortization expense increased $1.3 million mainly as a result of the amortization of intangible assets acquired in the Ultra Chem Acquisition. The increase was partially offset by a foreign exchange gain of approximately $1.3 million in the current period, driven primarily by fluctuations in the RMB and CAD compared to the USD.

The current period expense generated in the U.S. was partially offset by a benefit of $4.5 million on deferred tax liabilities as a result of the Tax Act. Income tax benefit for the six months endedMarch 31, 2017 was $1.9 million and was primarily attributable to U.S. operations related to deferred tax positions.

Liquidity and Capital Resources

Overview

Our primary sources of liquidity are cash flows generated from our operations and borrowing availability under the ABL Facility. Cash flows generated from operations are influenced by seasonal patterns of our business and other timing circumstances that can result in increases or decreases in working capital requirements for any given period during the course of our fiscal year. Our ability to generate sufficient cash flows from operating activities will continue to be primarily dependent on purchasing and distributing chemical and plastic materials. Additionally, our ability to generate cash flows in the normal course of business can be significantly influenced by changing global and regional macroeconomic conditions. Borrowing availability under the ABL Facility is subject to a borrowing base generally comprised of eligible inventory, accounts receivable and cash and cash equivalents held in certain accounts and certain subsidiaries. Our availability under the ABL Facility is, therefore, potentially subject to fluctuations, depending on the value of the eligible assets in the borrowing base on a given valuation date. An inability to borrow under the ABL Facility may adversely affect our liquidity, results of operations and financial condition. 

Our operating cash requirements consist principally of inventory purchases, trade credit extended to customers, labor, occupancy costs and transportation and delivery costs. Non-operating cash requirements include debt service requirements, acquisition-related costs and capital expenditures.

49

Capital Expenditures

Cash capital expenditures for the six months endedMarch 31, 2018 were $8.0 million and related primarily to facility improvements and additional information technology investments. We expect our aggregate capital expenditures for fiscal year 2018 (excluding acquisitions and any assets acquired via capital leases) to be approximately $35.0 million. Capital expenditures are expected to be primarily related to fixed asset and equipment replacements and improvements to our information technology infrastructure.

The ABL Facility provides for committed revolving credit financing including a U.S. Tranche of up to $505.0 million, a Canadian Tranche of up to the USD equivalent of $40.0 million and a FILO Tranche up to $30.0 million. The ABL Facility matures on June 9, 2021. Provided no default or event of default then exists or would arise therefrom, the ABL Borrowers have the option, at the beginning of each quarter, to request that the ABL Facility be increased by an aggregate amount, when included with any incremental borrowings issued under the Term Loan Facility, not to exceed $175.0 million.

The ABL Facility includes a letter of credit sub-facility, which permits up to $200.0 million of letters of credit under the U.S. Tranche (which may be denominated in USD, euros or other currencies approved by the administrative agent and the issuing bank) and up to the USD equivalent of $10.0 million of letters of credit under the Canadian Tranche (which may be denominated in CAD only). The ABL Facility also contains a FILO Tranche which can be used by any non-Canadian foreign subsidiary for loans or letters of credit up to an aggregate amount not to exceed $30.0 million.

Obligations under the ABL Facility are secured by a first priority lien on all ABL Facility first lien collateral, including eligible inventory and accounts receivable of the ABL Borrowers, and a second priority lien on all Term Loan Facility first lien collateral including outstanding equity interests of the Borrower and certain of the other subsidiaries of Holdings, in each case, subject to certain limitations; provided, that no ABL Facility first lien collateral or Term Loan Facility first lien collateral owned by the Canadian Borrower secure the obligations owing under the U.S. tranche of the ABL Facility.

At March 31, 2018, we had $179.0 million in borrowings outstanding under the ABL Facility. Interest expense related to the ABL Facility, excluding amortization of debt issuance costs, was $2.1 million and $4.0 million for the three and six months ended March 31, 2018, respectively, and $1.5 million and $2.8 million for the three and six months ended March 31, 2017, respectively.

As of March 31, 2018, we were in compliance with the covenants of the ABL Facility.

Term Loan Facility

The Term Loan Facility provides secured debt financing in an aggregate principal amount of up to $655.0 million and the right, at our option, to request additional tranches of term loans in an aggregate principal amount, when included with any incremental borrowings issued under the ABL Facility, amount up to $175.0 million, plus unlimited additional amounts such that the aggregate principal amount of indebtedness outstanding at the time of incurrence does not cause the Secured Net Leverage Ratio, calculated on a pro forma basis, to exceed 4.1 to 1.0. Availability of such additional tranches of term loans is subject to the absence of any default, and among other things, the receipt of commitments by existing or additional financial institutions. The Term Loan Facility matures on June 9, 2023.

50

On December 19, 2017, we completed TLB Amendment No. 2 amending the Term Loan Facility. TLB Amendment No. 2 reduced the interest rate margin applicable to outstanding term loans by 50 basis points from 3.75% to 3.25% for LIBOR loans and from 2.75% to 2.25% for base rate loans. TLB Amendment No. 2 also provides for a soft call premium equal to 1% of the amount of the term loans that are subject to certain repricing transactions occurring on or prior to twelve months from the effective date of TLB Amendment No. 2. As a result of TLB Amendment No. 2, we paid debt issuance costs of $0.8 million, which will be amortized throughout the remaining life of the Term Loan Facility. TLB Amendment No. 2 will result in an estimated $3.2 million reduction to our annual cash interest expense for each of the next five years, while all other terms of the Term Loan Facility remain unchanged. There were no changes to the total or secured leverage ratios.

Obligations under the Term Loan Facility are secured by a first priority lien on all Term Loan Facility first lien collateral, including outstanding equity interests of the Borrower and certain of the other subsidiaries of Holdings, and a second priority lien on all ABL Facility first lien collateral, including accounts receivable and inventory of the loan parties under the Term Loan Facility, subject to certain limitations.

At March 31, 2018, we had $643.6 million in borrowings outstanding under the Term Loan Facility. We are required to make mandatory principal payments on an annual basis, commencing with the fiscal year ending September 30, 2017, if cash flows for the year, as defined in the agreement, exceed certain levels specified in the agreement. We were not required to make such principal payment for fiscal year 2017. Interest expense related to the Term Loan Facility, excluding original issue discount amortization and amortization of debt issuance costs, was $7.9 million and $16.2 million for the three and six months ended March 31, 2018, respectively and $8.5 million and $17.3 million for the three and six months ended March 31, 2017, respectively.

As of March 31, 2018, we were in compliance with the covenants of the Term Loan Facility.

Liquidity

The following table summarizes our liquidity position as of March 31, 2018 and September 30, 2017:

	March 31, 2018		September 30, 2017
Cash and cash equivalents	$	42.4	$	53.9
ABL Facility availability	279.7		277.8
Total liquidity	$	322.1	$	331.7

Cash and Cash Equivalents

At March 31, 2018, we had $42.4 million in cash and cash equivalents of which $39.2 million was held by foreign subsidiaries, $35.5 million of which was denominated in currencies other than the USD, primarily in euros and CAD, and $5.1 million in China denominated in RMB. While the RMB is convertible into USD, foreign exchange transactions are subject to approvals from the SAFE. We do not anticipate any significant adverse impact to overall liquidity from potential limitations on the transfer or conversion of cash and cash equivalents.

ABL Facility

Under the ABL Facility, if as of any date of determination when Trigger Event Excess Availability (as defined in the ABL Facility) is below certain thresholds or upon certain defaults, we will be required to deposit cash on a daily basis from certain depository accounts in a collection account maintained with the administrative agent, which will be used to repay outstanding loans and cash collateralized letters of credit. Such requirement will be deemed continuing until the Trigger Event Excess Availability exceeds such threshold amount for 20 consecutive days. At March 31, 2018, Trigger Event Excess Availability under the ABL Facility was $279.7 million, which was $228.9 million in excess of the $50.8 million threshold that would trigger the foregoing requirements.

Based on current and anticipated levels of operations, capital spending projections and conditions in our markets, we believe that cash on hand, together with cash flows from operations and borrowings available under the ABL Facility, are adequate to meet our working capital and capital expenditure needs as well as any debt service and other cash requirements for at least twelve months.

51

In addition to operating and non-operating cash requirements previously described, our longer-term liquidity needs are primarily related to our final maturity debt payments due in 2021 and 2023. Depending on market conditions and other factors, we may also consider alternative financing options, including, but not limited to, issuance of equity, issuance of debt or refinancing of our existing debt obligations.

Cash Flows

The following table sets forth the major categories of our cash flows for the six months endedMarch 31, 2018 and 2017:

Net cash used by operating activities was impacted by the items specified below:

52

• Accounts and notes receivable increased $70.4 million primarily driven by higher sales volumes and rising average selling prices experienced during the period as well as timing of collections at period end. There were no significant changes in billing terms or collection processes during the six months endedMarch 31, 2017.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Commodity and Product Price Risk

Our business model is to buy and sell products at current market prices in quantities approximately equal to estimated customer demand. Energy costs are a significant component of raw materials that are included in our product costs. Rising or volatile raw material prices for our suppliers, especially those of hydrocarbon derivatives, may cause our costs to increase or may result in volatility in our profitability. Although we do not speculate on changes in the prices of the products we sell, because we maintain inventories in order to serve the needs of our customers, we are subject to the risk of reductions in market prices for products we hold in inventory. We do not use derivatives to manage our commodity price risk because of the large number of products we sell and the large variety of raw materials used in the production of those products. Inventory management practices are focused on managing product price risk by generally purchasing our inventories via our ERP system which helps us forecast customer demand based on historical practices. Global inventory balances can fluctuate based on variations in regional customer demand forecasts. We collaborate directly with customers in all regions to enhance the ongoing accuracy of these forecasts in order to reduce the number of days sales held in inventories, as well as lower the amount of any slow moving and older inventories. In addition, we are generally able to pass on price increases to our customers, subject to market conditions, such as declining or otherwise volatile market prices for feedstocks, the presence of competitors in particular geographic and product markets and prevailing pricing mechanisms in customer contracts. We believe that these risk management practices reduce our exposure to changes in product selling prices or costs; however, significant unanticipated changes in market conditions or commodity prices could adversely affect our results of operations, financial condition and cash flows, as the prices of the products we purchase and sell are volatile.

Credit Risk

We are subject to the risk of loss arising from the credit risk related to the possible inability of our customers to pay for the products we resell and distribute to them. We attempt to limit our credit risk by monitoring the creditworthiness of our customers to whom we extend credit and establish credit limits in accordance with our credit policy. We perform credit evaluations on substantially all customers requesting credit and we will not extend credit to customers for whom we have substantial concerns and will deal with those customers on a cash basis. With the exception of our operations in China, we generally do not require collateral with respect to credit extended to customers; however, we will not extend credit to customers for whom we have substantial concerns and will deal with those customers on a cash basis. Our operations in China offer billing terms that allow certain customers to remit payment during a period of time ranging from 30 days to nine months. These notes receivable ($7.6 million at March 31, 2018) are supported by banknotes issued by large banks in China on behalf of their customers.

At March 31, 2018, no individual customer represented greater than 5.0% of the outstanding accounts receivable balance.

Interest Rate Risk

Interest rate risks can occur due to changes in market interest rates. This risk results from changes in the fair values of fixed-interest rate financial instruments or from changes in the cash flows of variable interest rate financial instruments. The optimal structure of variable and fixed interest rates is determined as part of interest rate risk management. It is not possible to simultaneously minimize both kinds of interest rate risk. We take steps to mitigate interest rate risk in part by entering into interest rate swap agreements as described under “Fair Value Measurements” below. Also, see Note 8 to our condensed consolidated financial statements.

Borrowings under our ABL Facility bear a variable interest rate, which was a weighted average rate of 2.88% for the three months endedMarch 31, 2018. For each $100.0 million drawn on the ABL Facility, a 100 basis point increase in the interest rate would result in a $1.0 million increase in annual interest expense.

On December 19, 2017, we completed TLB Amendment No. 2 amending the Term Loan Facility. TLB Amendment No. 2 reduced the interest rate margin applicable to outstanding term loans by 50 basis points from 3.75% to 3.25% for LIBOR loans and from 2.75% to 2.25% for base rate loans. TLB Amendment No. 2 also provides for a soft call premium equal to 1% of the amount of the term loans that are subject to certain repricing transactions occurring on or prior to twelve months from the effective date of TLB Amendment No. 2.

55

Changes in market interest rates will have an effect on the Term Loan Facility interest expense. A 100 basis point increase/decrease in the interest rate would result in an increase/decrease of $6.4 million in annual interest expense based on the Term Loan Facility balance.

Fair Value Measurements

Contingent Consideration

As a result of the Business Combination, we incurred liabilities related to contingent consideration payable to the Selling Equityholders, which are required to be adjusted to fair value at each reporting period. These measurements are considered Level 3 measurements within the fair value hierarchy. Projected taxable income, current interest rates, current tax rates and the market price of our common stock are key inputs used to estimate the fair value of these liabilities. As a result, any changes in these inputs will impact the fair value of these liabilities and could materially impact the amount of income or expense recorded each reporting period.

The fair value of the liability for the contingent consideration related to the TRA was $75.8 million as of March 31, 2018. The calculation of the liability for the contingent consideration related to the TRA uses a cash flow model which incorporates current interest rates in the discount rate used to discount the obligation to present value. A 100 basis point increase in the discount rate compared to the discount rate used at the March 31, 2018 valuation would have resulted in a decrease of approximately $0.3 million in the value of the liability for the contingent consideration related to the TRA. Additionally, this cash flow model is sensitive to changes in applicable tax rates. A 100 basis point increase in the tax rate compared to the tax rate used at the March 31, 2018 valuation would have resulted in an increase of approximately $2.4 million in the value of the liability for the contingent consideration related to the TRA.

The fair value of the liability for the contingent consideration related to Deferred Cash Consideration was $54.2 million as of March 31, 2018. The liability for the contingent consideration related to the Deferred Cash Consideration is highly sensitive to the price of our common stock at each valuation date. A $1.00 increase/decrease in the price of our common stock from its March 31, 2018 price would have increased/decreased the fair value of the liability for the Deferred Cash Consideration by approximately $5.1 million.

Derivatives

During the three months ended March 31, 2018, we entered into three additional interest rate swap agreements with a combined notional amount of $300.0 million to help mitigate interest rate risk related to the variable rate Term Loan Facility. During the three months ended March 31, 2017, we entered into four interest rate swap agreements with a combined notional amount of $300.0 million to help mitigate interest rate risk related to the variable rate Term Loan Facility. The swap agreements expire at various dates from February 2020 through February 2023 and are accounted for as cash flow hedges. Gains or losses resulting from changes in the fair value of the swaps are recorded in other comprehensive income. Gains and losses recorded in other comprehensive income are reclassified into and recognized in income when the interest expense on the Term Loan Facility is recognized. At March 31, 2018, we recorded a net asset of $4.9 million in the condensed consolidated balance sheet related to these instruments.

During the six months endedMarch 31, 2018, we reclassified into income and recognized a realized loss on the interest rate swaps of $0.7 million, which was recorded in interest expense. During the six months endedMarch 31, 2018, we recorded an unrealized gain on the interest rate swaps (net of taxes and reclassifications into income) of $4.1 million, which was recorded in other comprehensive income. As of March 31, 2018, $0.6 million in unrealized gains were expected to be realized and recognized in income within the next twelve months.

56

Foreign Currency Risk

We may be adversely affected by foreign exchange rate fluctuations since we conduct our business on an international basis in multiple currencies. A portion of our sales and costs of sales are denominated in currencies other than the functional currency of our subsidiaries, exposing us to currency transaction risk.  Additionally, because we report our consolidated results in USD, the results of operations and the financial position of our local international operations, which are generally reported in the relevant local currencies, are translated into USD at the applicable exchange rates for inclusion in our condensed consolidated financial statements, exposing us to currency translation risk.  Further, we have exposure to foreign exchange fluctuations arising from the remeasurement of certain foreign operations where the USD is the functional currency but accounting records are kept in local currency. In this respect, we are vulnerable to currency remeasurement gains and losses to the extent that monetary assets and liabilities denominated in local currency do not offset each other when remeasured into USD.

We currently do not utilize financial derivatives to manage our foreign currency risk, but we continue to monitor our exposure to foreign currency risk, employ operational strategies where practical and may consider utilizing financial derivatives in the future to mitigate losses associated with these foreign currency risks.

Included in our condensed consolidated statements of operations for the six months endedMarch 31, 2018 is a $0.5 million net gain related to foreign exchange rate fluctuations, including a $0.2 million net remeasurement loss. The most significant currency exposures during this period were to the RMB, CAD and the Peso versus the USD. These currencies fluctuated to various degrees but such fluctuations did not exceed 5% from their respective values since September 30, 2017. Assuming the same directional fluctuations as occurred during the six months endedMarch 31, 2018, a hypothetical 10.0% weakening/strengthening in the average exchange rates of these currencies from that date would have generated a net loss/gain of $9.2 million in our condensed consolidated statements of operations for the six months endedMarch 31, 2018.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures 

As required by Rule 13a-15(b) under the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Our disclosure controls and procedures are designed to ensure that the information required to be disclosed by us in reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based on the evaluation performed, our management, including the principal executive officer and principal financial officer, concluded that the disclosure controls and procedures were effective as of March 31, 2018.

Changes in Internal Control over Financial Reporting

Our Chief Executive Officer and Chief Financial Officer evaluated the changes in our internal control over financial reporting that occurred during the quarterly period covered by this Quarterly Report on Form 10-Q. Based on their evaluation, it is concluded that there had been no change in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2018 that have materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

57

PART II

Item 1. Legal Proceedings

We are not currently a party to any legal proceedings that, if determined adversely against us, individually or in the aggregate, would have a material adverse effect on our financial position, results of operations or cash flows.     

In July 2014, Ashland filed a lawsuit -- 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 sought a declaration that Solutions was obligated to indemnify Ashland for losses Ashland incurred pertaining to the Other Retained Remediation Liabilities, up to the amount of a $5.0 million deductible, which Ashland contended applies pursuant to the ADA Purchase Agreement. Ashland further alleged that Solutions breached duties related to that agreement by not having so indemnified Ashland for amounts Ashland incurred for the Other Retained Remediation Liabilities at sites where Ashland disposed of wastes prior to the Ashland Distribution Acquisition, and on that basis sought unspecified compensatory damages, costs and attorney’s fees. On June 21, 2017 the Company’s Motion for Summary Judgment in this lawsuit was granted. Ashland appealed the ruling on July 20, 2017. On January 31, 2018, the Delaware Supreme Court affirmed the lower court’s grant of the Company’s Motion for Summary Judgment. Ashland did not request rehearing of the ruling. Therefore, the judgment in the Company’s favor is final and this matter is closed.

In June 2014, we self-disclosed to the DTSC that an inventory of our Fairfield facility had revealed potential violations of RCRA and the California Health and Safety Code. Although no formal proceeding has been initiated, we expect the DTSC to seek payment of fines or other penalties for non-compliance. We do not expect the amount of any such fine or penalty to have a material adverse effect on our business, financial position or results of operations.

From time to time, we are party to ongoing legal proceedings in the ordinary course of business. While the outcome of these proceedings cannot be predicted with certainty, we do not believe the results of these proceedings, other than as is disclosed elsewhere in this Quarterly Report on Form 10-Q, individually or in the aggregate, will have a material adverse effect on our business, financial condition, results of operation or liquidity.

58

Item 1A. Risk Factors

We are subject to certain risks and hazards due to the nature of the business activities we conduct. For a discussion of these risks, see “Item 1A. Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended September 30, 2017 filed with the SEC on December 7, 2017. These risks could materially and adversely affect our business, financial condition, cash flows and result of operations. There have been no material changes to the risk factors described in the Form 10-K described above. We may experience additional risks and uncertainties not currently known to us or, as a result of developments occurring in the future, conditions that we currently deem to be immaterial may also materially and adversely affect our business, financial condition and results of operations.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Recent Accounting Pronouncements Adopted

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. The amendments in this ASU require an entity to measure inventory at the lower of cost or net realizable value, whereas guidance previously required an assessment of market value of inventory, with different possibilities for determining market value. This ASU is effective for fiscal years beginning after December 15, 2016 and interim periods within those years and early adoption is permitted. The Company adopted this standard as of October 1, 2017, and it did not have a material effect on the Company’s financial position or results of operations.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The updated guidance simplifies several aspects of accounting for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as the classification of related matters in the statement of cash flows. This ASU is effective for annual reporting periods beginning after December 15, 2016 and interim periods within those annual periods. The Company adopted this standard as of October 1, 2017 and it did not have a material effect on the Company’s financial position or results of operations.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): This ASU clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as a modified award. The new guidance will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications.  The amendments in this ASU will be applied prospectively to awards modified on or after the adoption date. The Company adopted this standard as of October 1, 2017 and it did not have a material effect on the Company’s financial position or results of operations.

New Accounting Pronouncements Not Yet Adopted

The Company continues the evaluation of the potential effects on its financial position or results of operations of the accounting pronouncements disclosed in its consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2017 filed with the SEC on December 7, 2017, including ASU 2014-09, Revenue from Contracts with Customers and ASU 2016-02, Leases. With regards to ASU 2014-09, the Company continues to work on the identification, design and implementation of changes to its accounting systems, policies and internal controls to support the recognition and disclosure requirements under the new revenue recognition standard. However, the Company does not anticipate the adoption of the guidance will have a material effect on the amount or the timing of revenue recognition associated with the majority of its customer contracts given their general terms and duration. The Company expects to utilize the modified retrospective method of adoption by recognizing the cumulative effect of the adoption change as an adjustment to beginning of period retained earnings for the first quarter of fiscal 2019.

The Company is in the process of evaluating the potential effects of ASU 2016-02 and is formulating its implementation plan, including potential changes to accounting systems, policies and internal controls to support the adoption of the new guidance.

Acquisitions

Ultra Chem Acquisition

On April 3, 2017, the Company completed the Ultra Chem Acquisition for $56.7 million, net of cash acquired of $0.5 million, pursuant to the Ultra Chem Stock Purchase Agreement.  As of March 31, 2018, $9.7 million of the purchase price may remain in escrow for a period of up to five years from the closing of the acquisition and relates to indemnification obligations under the Ultra Chem Stock Purchase Agreement. The escrow amount will be released pursuant to the terms of the Ultra Chem Stock Purchase Agreement and related documentation. The Ultra Chem Acquisition was financed with approximately $58.0 million of borrowings under the ABL Facility. There is no contingent consideration related to the Ultra Chem Acquisition.

Purchase Price Allocation

The Ultra Chem Acquisition is accounted for under the acquisition method, which requires the Company to perform an allocation of the purchase consideration to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase consideration over the estimated fair values is recorded as goodwill. The following table summarizes the Company’s allocation of the purchase consideration to assets acquired and liabilities assumed at the Ultra Chem Closing Date:

	Purchase Consideration Allocation
Accounts receivable	$	13.7
Inventory	9.1
Other current assets	2.4
Property and equipment	0.5
Customer-related intangible	24.0
Trade name	0.3
Non-compete agreements	3.9
Other non-current assets	2.5
Goodwill	28.0
Total assets acquired	84.4
Short-term borrowings	0.9
Accounts payable	12.1
Other current liabilities	4.1
Deferred tax liability — non-current	8.4
Other non-current liabilities	2.2
Total liabilities assumed	27.7
Net assets acquired	$	56.7

During the three months ended March 31, 2018, the Company completed its assessment of the fair values of the assets acquired and liabilities assumed in the Ultra Chem Acquisition. The Company recorded no material adjustments to the fair value estimates of assets and liabilities during the current period.

There were no transaction costs incurred by the Company associated with the Ultra Chem Acquisition during the three months endedMarch 31, 2018. Transaction costs incurred by the Company associated with the Ultra Chem Acquisition were $0.1 million during the six months ended March 31, 2018 and $0.1 million during the three and six months ended March 31, 2017.

A summary and description of the acquired assets and assumed liabilities fair valued in conjunction with applying the acquisition method of accounting follows:

Accounts Receivable

Accounts and notes receivable consisted of receivables related to the customers of the acquired business, as well as various other miscellaneous receivables. The accounts receivable and other miscellaneous receivables were recorded at their approximate fair value based on expected collections of the Ultra Chem Group. Accordingly, accounts receivable included an adjustment of $1.5 million to reduce gross receivables to their net value after consideration of expected uncollectable amounts at the Ultra Chem Closing Date.

Inventory

Inventory consisted primarily of finished products to be distributed to the acquired business’s customers. The fair value of inventory was established through application of the income approach, using estimates of selling prices and costs such as selling and marketing expenses to be incurred in order to dispose of the finished products and arriving at the future profitability expected to be generated once the inventory is sold (net realizable value). The inventory fair value step up of $1.0 million was recognized in Cost of sales and operating expenses during the fiscal year ended September 30, 2017.

Other Current Assets

Other current assets consisted primarily of prepaid expenses and did not have a fair value adjustment as part of acquisition accounting since their carrying value approximated fair value. Other current assets also include indemnification assets recorded in connection with the recognition of tax-related contingent liabilities assumed. The indemnification assets represent the reimbursement the Company would reasonably expect to receive from funds initially held in escrow pursuant to the purchase agreement if the liabilities were asserted by the relevant tax authority.

Property and Equipment

Property and equipment acquired consists primarily of leasehold improvements, computer and office equipment as well as furniture and fixtures. The purchase price allocation for property and equipment was based on the carrying value of such assets as it was determined to approximate fair value.

Customer-Related Intangible

Customer relationships were valued through the application of the income approach. Under this approach, revenue, operating expenses and other costs associated with existing customers were estimated in order to derive cash flows attributable to the existing customer relationships. The resulting estimated cash flows were then discounted to present value to arrive at the fair value of existing customer relationships as of the valuation date. The value associated with customer relationships will be amortized on a straight-line basis over a ten-year period, which represents the approximate point in the projection period in which a majority of the asset’s cash flows are expected to be realized based on assumed attrition rates. The Company recognized $24.0 million for these intangible assets as part of the allocation of the purchase consideration.

Trade Name

The "Ultra Chem" trade name was valued through application of the income approach, involving the estimation of likely future sales and an estimated royalty rate reflective of the rate that a market participant would pay to use the "Ultra Chem" name. The fair value of this asset will be amortized on a straight-line basis over a two-year period, estimated based on the period in which the Company would expect a market participant to use the name prior to rebranding. The Company recognized $0.3 million for this intangible asset as part of the allocation of the purchase consideration.

Non-Compete Agreements

In connection with the Ultra Chem Acquisition, the former equityholders of the Ultra Chem Group agreed to non-compete agreements. The terms of the non-compete agreements prohibit the equityholders from competing in the chemical distribution space for three years after the Ultra Chem Closing Date. The income approach was used to value the non-compete agreements through a comparative discounted cash flow analysis based on the impact of competition absent these agreements. The Company recognized $3.9 million for this intangible asset as part of the allocation of the purchase consideration. This intangible is amortized on a straight-line basis over a three-year period.

Other Non-Current Assets

Other non-current assets acquired represented certain long-term deposits and other assets, which did not have a fair value adjustment as part of acquisition accounting since their carrying value approximated fair value. Other non-current assets also included indemnification assets recorded in connection with the recognition of tax-related contingent liabilities assumed, and the expected value of certain assets pledged as a guarantee to the Ultra Chem Group in connection with transactions with a particular customer. The indemnification assets represent the reimbursement the Company reasonably expects to receive from funds initially held in escrow pursuant to the purchase agreement if the related liabilities were asserted by the relevant tax authority.

Goodwill

Goodwill represents the excess of the total purchase price over the fair value of the underlying net assets, largely arising from synergies expected as a result of the Ultra Chem Acquisition. Goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually, absent any indicators of impairment. The Company does not expect any goodwill from the Ultra Chem Acquisition to be deductible for tax purposes.

Short-Term Borrowings

Short-term borrowings included short-term borrowings of the Ultra Chem Group prior to the Ultra Chem Acquisition, which did not have a fair value adjustment as part of acquisition accounting as their carrying value approximated fair value. The balance was paid off immediately after the closing of the Ultra Chem Acquisition.

Accounts Payable

Accounts payable represented short-term obligations owed to the vendors of the acquired business, which were assumed in the Ultra Chem Acquisition. These obligations did not have a fair value adjustment as part of acquisition accounting as their carrying value approximated fair value.

Other Current Liabilities

Other current liabilities represented primarily accrued expenses, including accrued payroll, certain accrued taxes, the current portion of assumed tax-related contingent liabilities and various other liabilities arising out of the normal operations of the acquired business. The majority of these liabilities did not have a fair value adjustment as their carrying value approximated fair value.

Other Non-Current Liabilities

Other non-current liabilities represent assumed tax-related contingent liabilities, and the expected value of certain assets pledged as a guarantee to the Ultra Chem Group which would have to be returned to the third party under certain circumstances.

Deferred Taxes

Deferred tax assets and liabilities are attributable to the difference between the estimated fair values allocated to inventory, property and equipment and identified intangibles acquired for financial reporting purposes and the amounts determined for tax reporting purposes and give rise to temporary differences.  The deferred tax assets and liabilities will reverse in future periods or have reversed as the related tangible and intangible assets are amortized, acquired inventory is sold, or if goodwill is impaired.

Due to Related Party Pursuant to ContingentConsideration Obligations

Contingent Consideration - Deferred Cash Consideration

The contingent consideration associated with the Deferred Cash Consideration willbe an amount in cash equal to the prevailing price of the Company’s common stock at the time that the Company pays such deferred cash payment multiplied by the number of Excess Shares (5,178,642 Excess Shares as of March 31, 2018).  Based on the terms of the Excess Shares, certain circumstances require the Company to pay all or a portion of the Deferred Cash Consideration to the Selling Equityholders, where such cash amount is calculated as set forth in the Merger Agreement, including (i) where the volume weighted average trading price of the Company’s common stock for any period of 20 trading days in any 30 trading day period exceeds $15.00 per share, and (ii) if any Excess Shares remain on June 30, 2021. If any Excess Shares remain on June 30, 2021, the Company must elect to either (i) within five business days of such date, pay the Selling Equityholders an amount in cash equal to the product of the number of remaining Excess Shares multiplied by the volume weighted-average trading price for the 20 trading day period immediately preceding such date or (ii) use reasonable best efforts to sell such shares to a third party in a primary offering and pay the gross proceeds thereof (less any underwriting discounts and commissions) to the Selling Equityholders. However, to the extent the number of shares issued in such offerings does not equal the full amount of Excess Shares remaining at the time of the offering, the Company’s obligations with respect to any remaining Excess Shares, including the obligation to continue to complete any necessary additional offerings, shall continue.

In order to estimate the fair value of the Deferred Cash Consideration, the Company estimates the value of the Excess Shares using a Monte Carlo simulation model. The estimated fair value of the Deferred Cash Consideration liability was $54.2 million and $35.1 millionas of March 31, 2018 and September 30, 2017, respectively. See Note 9.

Contingent Consideration - TRA

Concurrent with the completion of the Business Combination, the Company incurred the liability for contingent consideration related to the TRA, which reflects amounts owed to the Selling Equityholders. This liability generally provides for the payment by the Company to the Selling Equityholders of 85% of the net cash savings, if any, in U.S. federal, state and local income taxes that the Company actually realizes (or is deemed to realize in certain circumstances) in periods after the Closing Date as a result of (i) certain increases in tax basis resulting from the Company Merger, (ii) certain tax attributes of Holdings existing prior to the Mergers, (iii) net operating losses and certain other tax attributes of Blocker available to the Company as a result of the Blocker Merger and (iv) imputed interest deemed to be paid by the Company as a result of, and additional tax basis arising from, payments the Company makes under the TRA. The Company will retain the benefit of the remaining 15% of the net cash savings, if any. The Company estimated the fair value of the TRA liability based on a discounted cash flow model which incorporates assumptions of projected taxable income, projected income tax liabilities and an estimate of tax benefits expected to be realized as a result of the Business Combination. The current undiscounted cash flows associated with the TRA liability were estimated to be approximately $136.6 million over the time period during which the tax benefits are expected to be realized, currently estimated at over 20 years. The estimated fair value of the TRA liability is $75.8 million and $105.1 million as of March 31, 2018 and September 30, 2017, respectively. See Note 9. The decrease in the liability is reflective of the provisional impact associated with the Tax Act enacted in December 2017 (see Note 15), which lowers the Company’s projected income tax liabilities, the estimate of tax benefits expected to be realized as a result of the Business Combination and the ultimate amount expected to be paid by the Company to the Selling Equityholders.

The amount and timing of any payments due under the TRA will vary depending upon a number of factors, including the amount and timing of the taxable income the Company generates in the future and the U.S. federal, state and local income tax rates then applicable. In addition, payments made under the TRA will give rise to additional tax benefits for the Company and therefore additional potential payments due under the TRA. The term of the TRA commenced upon the consummation of the Mergers and will continue until all tax benefits that are subject to the TRA have been utilized or expired, unless the Company exercises its right to terminate the TRA early. If the Company elects to terminate the TRA early, its obligations under the TRA would accelerate and it generally would be required to make an immediate payment equal to the present value of the anticipated future payments to be made by it under the TRA, calculated in accordance with certain valuation assumptions set forth in the TRA.

Goodwill amounts by reportable segment at March 31, 2018 include the allocation of the purchase consideration of the Ultra Chem Acquisition as of the Ultra Chem Closing Date. See Note 3.

Goodwill Impairment Test

Goodwill is tested for impairment annually as of March 31 and whenever events or circumstances make it more likely than not that an impairment may have occurred. Goodwill is reviewed for impairment at the reporting unit level, or operating segment, for the Company. The Company performed an impairment test as of March 31 2018 and concluded that goodwill was not impaired. For purposes of the impairment testing of the Company's recognized goodwill, fair value measurements are determined using the income approach, based largely on inputs that are not observable to active markets, which would be deemed Level 3 fair value measurements as defined in Note 9.

The evaluation of goodwill requires the use of estimates about future operating results of each reporting unit to determine its estimated fair value. Changes in forecasted operations can materially affect these estimates, which could materially affect the Company’s results of operations. The estimate of fair value requires significant judgment and is based on management’s fair value estimates on assumptions that are believed to be reasonable but that are unpredictable and inherently uncertain, including: estimates of future growth rates, operating margins and assumptions about the overall economic climate as well as the competitive environment for the reporting units. There can be no assurance that these estimates and assumptions made for purposes of the goodwill testing as of the time of testing will prove to be accurate. If assumptions regarding business plans, competitive environments or anticipated growth rates are not correct, the Company may be required to record goodwill impairment charges in future periods, whether in connection with future annual impairment testing, or earlier, if an indicator of an impairment is present prior to the next annual evaluation.

The Company had the USD equivalent of $74.2 million in outstanding letters of credit under the ABL Facility at March 31, 2018. The collective credit availability under the U.S. and Canadian Tranches of the ABL Facility was the U.S. equivalent of $279.7 million at March 31, 2018. There was $5.0 million availability under the FILO Tranche at March 31, 2018. The ABL Facility matures on June 9, 2021.

Obligations under the ABL Facility are secured by a first priority lien on all ABL Facility first lien collateral, including eligible inventory and accounts receivable of the ABL Borrowers, and a second priority lien on all Term Loan Facility first lien collateral including outstanding equity interests of the Borrower and certain of the other subsidiaries of Holdings, in each case, subject to certain limitations; provided, that no ABL Facility first lien collateral or Term Loan Facility first lien collateral owned by the Canadian Borrower secure the obligations owing under the U.S. tranche of the ABL Facility. These accounts receivable and inventory totaled $724.7 million in the aggregate as of March 31, 2018.

As of March 31, 2018, the ABL Borrowers were in compliance with the covenants of the ABL Facility.

Term Loan Facility

The Term Loan Facility provides secured debt financing in an aggregate principal amount of up to $655.0 million and the right, at the Company’s option, to request additional tranches of term loans in an aggregate principal amount, when included with any incremental borrowings issued under the ABL Facility, of up to $175.0 million, plus unlimited additional amounts such that the aggregate principal amount of indebtedness outstanding at the time of incurrence does not cause the Secured Net Leverage Ratio, calculated on a pro forma basis, to exceed 4.1 to 1.0. Availability of such additional tranches of term loans is subject to the absence of any default and, among other things, the receipt of commitments by existing or additional financial institutions.

On December 19, 2017, the Company completed TLB Amendment No. 2 amending the Term Loan Facility. TLB Amendment No. 2 reduced the interest rate margin applicable to outstanding term loans by 50 basis points from 3.75% to 3.25% for LIBOR loans and from 2.75% to 2.25% for base rate loans. TLB Amendment No. 2 also provides for a soft call premium equal to 1% of the amount of the term loans that are subject to certain repricing transactions occurring on or prior to twelve months from the effective date of TLB Amendment No. 2. As a result of TLB Amendment No. 2, the Company paid debt issuance costs of $0.8 million, which will be amortized throughout the remaining life of the Term Loan Facility.

The Company is required to make scheduled quarterly payments in an aggregate annual amount equal to 1.0% of the aggregate principal amount of the outstanding term loans as of the Closing Date of the TLB Amendment No. 2, with the balance due at maturity. The average interest rate for the Term Loan Facility was 4.89% at March 31, 2018. The Company amortized $0.1 million and $0.2 million of debt discount to interest expense during the three and six months ended March 31, 2018, respectively and $0.1 million and $0.3 million of debt discount to interest expense during the three and six months ended March 31, 2017, respectively. The Term Loan Facility matures on June 9, 2023.

Additionally, the Term Loan Facility requires the Company to make mandatory principal payments on an annual basis, commencing with the fiscal year ending September 30, 2017, if cash flows for the year, as defined in the Term Loan Facility, exceed certain levels specified in the Term Loan Facility. The Company was not required to make such mandatory principal payment for the fiscal year ended September 30, 2017. The Company generally has the right to prepay loans in whole or in part, without incurring any penalties for early payment.

Obligations under the Term Loan Facility are secured by a first priority lien on all Term Loan Facility first lien collateral, including outstanding equity interests of the Borrower and certain of the other subsidiaries of Holdings, and a second priority lien on all ABL Facility first lien collateral, including accounts receivable and inventory of the loan parties under the Term Loan Facility, subject to certain limitations.

As of March 31, 2018, the Company was in compliance with the covenants of the Term Loan Facility.

Debt Issuance Cost Amortization

Amortization expense included in interest expense related to debt issuance costs of the Term Loan Facility was $0.7 million and $1.4 million for the three and six months ended March 31, 2018, respectively, and $0.6 million and $1.1 million for the three and six months ended March 31, 2017, respectively.

Capital Lease Obligations

The capital lease obligation balance of $36.2 million as of March 31, 2018 is primarily associated with the Ryder Lease and the Montgomery Lease. The Ryder Lease obligation excludes decreasing annual interest payments ranging from $0.9 million to $0.1 million, for aggregate interest payments totaling $3.2 million. The Montgomery Lease obligation excludes decreasing annual interest payments ranging from $1.0 million to $0.1 million, for aggregate interest payments of $13.1 million.

Fair Value Measurements

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—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.

Fair value of financial instruments

The carrying values of cash and cash equivalents, accounts and notes receivable, accounts payable and short-term borrowings approximate their fair value due to the short-term maturity of those instruments.

The carrying values of borrowings outstanding under the Credit Facilities approximate fair value at March 31, 2018 and September 30, 2017, 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 due to the varying interest rate parameters as outlined in the respective loan agreements.

Assets and Liabilities Measured at Fair Value on a Non-Recurring 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 non-recurring basis as required by U.S. GAAP. Generally, assets are recorded at fair value on a non-recurring basis as a result of impairment charges or as part of a business combination. As discussed in Note 3, during the fiscal year ended September 30, 2017, the Company recorded non-recurring fair value measurements related to the Ultra Chem Acquisition and its asset acquisitions. These fair value measurements were classified as Level 3 within the fair value hierarchy.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Contingent Consideration

The fair value of the contingent consideration related to the Deferred Cash Consideration as discussed in Note 4 was $54.2 million and $35.1 million as of March 31, 2018 and September 30, 2017, respectively. The increase in the liability was largely driven by the increase in the Company’s stock price. The measurement of the contingent consideration related to the Deferred Cash Consideration is classified by the Company as a Level 3 measurement within the fair value hierarchy. In order to estimate the fair value of the Deferred Cash Consideration, the Company estimates the value of the Excess Shares using a Monte Carlo simulation model with the market price of the Company’s common stock at each valuation date being a significant input to this model. Unobservable inputs to the valuation are the expected volatility during the applicable period as well as a marketability discount to reflect the illiquidity of the Excess Shares given their terms. An increase in the market price of the Company’s common stock has the same directional effect on the value of the liability related to the Deferred Cash Consideration. An increase in the volatility and marketability discount will lower the value of the liability related to the Deferred Cash Consideration.

The fair value of the liability for the contingent consideration related to the TRA as discussed in Note 4 was $75.8 million and $105.1 million as of March 31, 2018 and September 30, 2017, respectively. The decrease in the liability is reflective of the provisional impact associated with the Tax Act enacted in December 2017 (see Note 15), which lowers the Company’s projected income tax liabilities, the estimate of tax benefits expected to be realized as a result of the Business Combination and the ultimate amount expected to be paid by the Company to the Selling Equityholders. The liability for the contingent consideration related to the TRA is classified by the Company as a Level 3 measurement within the fair value hierarchy. The Company estimates the fair value of the liability for the contingent consideration related to the TRA based on a discounted cash flow model which incorporates assumptions of projected taxable income, projected income tax liabilities and an estimate of tax benefits expected to be realized as a result of the Business Combination. Key inputs to the valuation are prevailing tax rates and market interest rates impacting the discount rate. A 100 basis point increase in the discount rate compared to the discount rate used at the March 31, 2018 valuation would have resulted in a decrease of approximately $0.3 million in the value of the liability for the contingent consideration related to the TRA. Additionally, this cash flow model is sensitive to changes in prevailing tax rates. A 100 basis point increase in the tax rate compared to the tax rate used at the March 31, 2018 valuation would have resulted in an increase of approximately $2.4 million in the value of the liability for the contingent consideration related to the TRA.

Changes in the fair value of the contingent consideration obligations for the six months endedMarch 31, 2018 were as follows:

	TRA			Deferred Cash Consideration		Total Fair Value
Contingent consideration as of September 30, 2017	$	105.1		$	35.1	$	140.2
Cash paid to TPG	(4.2		)	—		(4.2		)
Change in fair value of contingent consideration(1)	(25.1		)	19.1		(6.0		)
Contingent consideration as of March 31, 2018	$	75.8		$	54.2	$	130.0

⁽¹⁾Included in Operating income in the condensed consolidated statements of operations.

Significant changes in the estimates and inputs used in determining the fair value of the contingent consideration could have a material impact on the amounts recognized as a component of Operating income in future periods.

Interest Rate Swaps

The Company classifies interest rate swaps within Level 2. During the three months ended March 31, 2018, the Company entered into three additional interest rate swap agreements to help mitigate interest rate risk related to the variable rate Term Loan Facility. During the three months ended March 31, 2017, the Company entered into four interest rate swap agreements to help mitigate interest rate risk related to the variable rate Term Loan Facility. The swap agreements expire at various dates through February 2023. At March 31, 2018, the Company recorded $1.1 million to Othercurrentassets, $4.7 million in Other non-current assets and$0.9 million in Accrued expenses and other liabilities in the condensed consolidated balance sheets related to these instruments.

During the six months endedMarch 31, 2018 and 2017, the Company did not have any transfers between Level 1, Level 2 or Level 3 fair value measurements.

Share-based Compensation and Employee Benefit Plans

On June 8, 2016, the Company’s stockholders approved the 2016 LTIP, with an effective date of March 30, 2016, covering approximately a ten-year period. No awards may be granted under the 2016 LTIP after March 20, 2026. The 2016 LTIP permits the grant of up to 9,000,000 shares of the Company's common stock for various types of awards to employees, directors and consultants of the Company or its subsidiaries, including incentive and non-incentive stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalents, stock awards, conversion awards and performance awards.

During the six months endedMarch 31, 2018, the Company granted 193,667 PSUs to employees under the 2016 LTIP. These awards will vest on September 30, 2020, entitling the recipient to receive a certain number of shares of the Company’s common stock, based on the Company’s achievement of the performance goals included in the PSUs, which are based on a return on invested capital calculation over a three-year performance period. Depending on the calculation as of the vesting date, a recipient is entitled to receive between 0% and 200% of the initial award. The awards are accounted for as equity instruments, and the fair value of these awards was determined by the closing price of the Company's common stock on the date of grant.

During the fiscal years ended September 30, 2017 and 2016, the Company granted 212,000 and 1,557,500 PSU awards to employees, respectively, under the 2016 LTIP. The recipient can receive between 0% and 200% of the initial award, based on the Company’s total stockholder return during approximate three-year performance period, or a cumulative Adjusted EBITDA target if a specified total stockholder return is not met. The Company used the Monte Carlo simulation model to estimate the fair value of the PSU awards at the grant date, factoring in the market-based vesting condition and considering the probability of satisfying the various performance criteria. The resulting grant date fair value is recognized as expense on a straight-line basis from the grant date through the end of the performance period. The assumptions used in the Monte Carlo simulation model for PSUs included an expected stock price volatility between 35% and 40% based on a peer group of similar companies, an expected dividend yield of 0%, an expected term of two to three years, and a risk-free interest rate of between 0.9% and 1.3%.

The following table summarizes all PSU activity during the six months endedMarch 31, 2018:

	PSUs		Average Grant Date Fair Value Per Unit
Unvested PSUs at September 30, 2017	1,524,000		$	8.92
Granted	193,667		7.50
Vested	—		—
Forfeited/Canceled	(22,500	)	9.13
Unvested PSUs at March 31, 2018	1,695,167		$	8.76

As of March 31, 2018, the Company may issue up to 3,390,334 shares of common stock related to the outstanding PSU awards described above under the 2016 LTIP. The PSU awards are accounted for as equity instruments, and the Company recognized compensation cost of $1.1 million and $2.3 million as a component of Selling, general and administrative expenses on the condensed consolidated statements of operations for the three and six months ended March 31, 2018, respectively, and $1.1 million and $2.2 million for the three and six months ended March 31, 2017, respectively, related to the PSUs. As of March 31, 2018, the outstanding PSUs had a weighted-average remaining contract life of 1.4 years. As of March 31, 2018, there was $6.5 million of total unrecognized compensation cost related to unvested PSUs.

In November 2017, the Company granted 415,867 shares of restricted stock to employees under the 2016 LTIP. The restricted stock awards vest equally on the anniversary of the grant date over a three-year period provided that the recipients of such grants continue their employment with the Company. The awards are accounted for as equity instruments, and the fair value of the restricted stock awards was determined by the closing price of the Company's common stock on the date of grant. During the fiscal years ended September 30, 2017 and 2016, the Company granted restricted stock awards to certain of the Company’s non-employee directors under the 2016 LTIP that vest one year from the date of grant.

The following table summarizes all restricted stock activity during the six months endedMarch 31, 2018:

	Shares of Restricted Stock		Average Grant Date Fair Value Per Unit
Restricted stock at September 30, 2017	77,458		$	8.26
Granted	415,867		7.50
Vested	—		—
Forfeited/Canceled	(24,008	)	8.20
Restricted stock at March 31, 2018	469,317		$	7.59

The restricted stock awards are accounted for as equity instruments, and the Company recognized compensation expense of $0.4 million and $0.7 million as a component of Selling, general and administrative expenses on the condensed consolidated statements of operations during the three and six months ended March 31, 2018, respectively, and $0.1 million and $0.3 million during the three and six months ended March 31, 2017, respectively, related to the restricted stock. As of March 31, 2018, there was $2.7 million of total unrecognized compensation expense related to restricted stock, and a weighted average remaining life of 2.3 years.

During the fiscal year ended September 30, 2016, the TPG Restricted Stock Grants were awarded with respect to 100,000 shares of Company common stock owned by TPG. These awards vest in equal amounts over a three-year period provided that the recipients of such grants continue their employment with the Company. During the six months ended March 31, 2018, 11,673 shares were transferred back to TPG due to forfeiture. During the fiscal year ended September 30, 2017, 33,333 shares of these awards vested and 9,576 shares were transferred to the Company (reflected as treasury stock) to satisfy the officers’ and employees’ tax withholding obligations in connection with the vesting. The Company recognized compensation cost of less than $0.1 million and $0.1 million as a component of Selling, general and administrative expenses on the condensed consolidated statements of operations for the three and six months ended March 31, 2018, respectively, and $0.1 million and $0.2 million for the three and six months ended March 31, 2017, respectively, related to these awards. As of March 31, 2018, there was $0.4 million of total unrecognized compensation cost related to these awards and a weighted average remaining life of 1.2 years. While these awards were not made pursuant to the 2016 LTIP, they constitute equity-based compensation and therefore will count against the 2016 LTIP's share reserve to the extent the awards vest.

During the six months endedMarch 31, 2018, the Company granted 999,492 stock options to employees under the 2016 LTIP. The awards vest in equal amounts over a three-year period provided that the recipients of such grants continue their employment with the Company. The Company used the Black-Scholes Merton model to estimate the fair value of the option awards at the grant date. The resulting grant date fair value is recognized as expense on a straight-line basis over the vesting period. The assumptions used in the Black-Scholes Merton model for the options included an expected term of six years, an expected stock price volatility of 35.0% based on a peer group of similar companies, an expected dividend yield of 0.0% and a risk-free interest rate of 2.1%.

The following table summarizes stock option activity during the six months endedMarch 31, 2018:

	Stock Options	Average Grant Date Fair Value Per Unit		Weighted Average Exercise Price
Stock Options at September 30, 2017	—	$	—	$	—
Granted	999,492	2.84		7.42
Exercised	—	—		—
Forfeited/Canceled	—	—		—
Stock Options at March 31, 2018	999,492	$	2.84	$	7.42

The stock options are accounted for as equity instruments, and the Company recognized compensation expense of $0.3 million and $0.4 million as a component of Selling, general and administrative expenses on the condensed consolidated statements of operations during the three and six months ended March 31, 2018, respectively, related to the restricted stock. As of March 31, 2018, there was $2.3 million of total unrecognized compensation expense related to stock options, and a weighted average remaining contractual life of 9.6 years. The outstanding stock options as of March 31, 2018 had an aggregate intrinsic value of $3.3 million. No stock options were exercisable as of March 31, 2018.

During the three months ended December 31, 2016, the Company granted certain employees a total of 28,000 RSUs under the 2016 LTIP that vest equally over a three-year period on the anniversary of the grant date provided the employee remains employed by the Company. Upon vesting, the recipients will receive a share of common stock in the Company for each RSU awarded. The fair value of these RSUs was determined based on the closing price of the Company’s stock on the grant date.

The following table summarizes RSU award activity during the six months endedMarch 31, 2018:

	RSUs		Average Grant Date Fair Value Per Unit
Unvested RSUs at September 30, 2017	24,500		$	7.28
Granted	—		—
Vested	(8,162	)	7.28
Forfeited/Canceled	—		—
Unvested RSUs at March 31, 2018	16,338		$	7.28

The RSUs are accounted for as equity instruments, and the Company recognized compensation cost of less than $0.1 million as a component of Selling, general and administrative expenses on the condensed consolidated statements of operations during the three and six months ended March 31, 2018 and 2017 related to the RSUs. During the six months ended March 31, 2018, 8,162 RSUs vested, and 2,777 shares were transferred to the Company (reflected as treasury stock) to satisfy the employees’ tax withholding obligations in connection with the vesting. As of March 31, 2018, there was $0.1 million of total unrecognized compensation cost related to the RSUs, and a weighted average remaining life of 1.6 years.

During the three months ended December 31, 2016, the Company also awarded 10,500 phantom RSUs and 10,000 phantom PSUs to certain non-U.S. employees under the 2016 LTIP. The phantom RSUs vest equally over a three-year period on the anniversary of the grant date while the phantom PSUs vest under the same conditions as the PSU awards described above. During the fiscal year ended September 30, 2017, 3,500 of the phantom RSUs were forfeited and all of the phantom PSUs were forfeited. Upon vesting and provided the employee remains employed by the Company at that time, the awards will be settled in cash. In accordance with ASC 718, the remaining phantom RSU awards are accounted for as a liability, with the awards re-measured at the end of each reporting period based on the closing price of the Company’s common stock or using a Monte Carlo simulation model, as applicable. Compensation expense is recognized ratably on a straight-line basis over the requisite service period. An immaterial amount of compensation expense was recognized during the three and six months ended March 31, 2018 and 2017 related to these awards.

As of March 31, 2018, there were 3,967,265 shares of the Company’s common stock available for issuance under the 2016 LTIP, assuming the PSU awards vest at their maximum target.

Dilutive computations during the current period contain additional incremental common shares which are attributable to the outstanding unvested restricted stock awards issued to directors and employees and restricted stock units awards to employees; the outstanding stock options were not included as the result would have been anti-dilutive. During the three and six months ended March 31, 2017, the outstanding restricted stock awards and restricted stock unit awards were not included as their impact on the Company’s net loss would have been anti-dilutive. For the three and six months ended March 31, 2018 and 2017, there were 12,476,250 Founder Shares excluded from the basic and diluted computations because such shares were subject to forfeiture, and PSU awards, which were not included in the computation of diluted shares outstanding because performance targets and/or market conditions were not yet met for these awards. Diluted shares outstanding also did not include 25,012,500 shares of common stock issuable on the exercise of 50,025,000 warrants because the warrants were out-of-the-money for the three and six months ended March 31, 2018 and 2017.

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, handling, transportation and disposal of chemicals and hazardous materials. These laws pertain to air and water, the management of solid and hazardous wastes, transportation and human health and safety.

On March 31, 2011, the Predecessor 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 ("the 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 received notice prior to the fifth anniversary of the closing (the "Other Retained Remediation Liabilities") (collectively, the "Retained Remediation Liabilities").  Ashland’s liability for the 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. Had the Predecessor incurred expenses arising out of the Other Retained Remediation Liabilities, Ashland’s indemnification obligation would have been subject to an individual claim threshold of $0.2 million and an aggregate claim deductible of $5.0 million. Ashland’s indemnification obligations under the ADA Purchase Agreement as described above terminated as of March 31, 2016, other than for the Retained Remediation Liabilities. 

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 sought a declaration that, pursuant to the ADA Purchase Agreement, Solutions was obligated to indemnify Ashland for losses Ashland incurred pertaining to the Other Retained Remediation Liabilities, up to the amount of the aggregate $5.0 million deductible applicable for expenses incurred by Solutions, whether or not Solutions incurs any expenses or obtained any indemnity from Ashland.  Ashland further alleged that Solutions breached duties related to the ADA Purchase Agreement by not having so indemnified Ashland for amounts Ashland incurred for Other Retained Remediation Liabilities at sites where Ashland disposed of wastes prior to the Ashland Distribution Acquisition, and on that basis sought unspecified compensatory damages, costs and attorney’s fees.  On June 21, 2017, the Company’s Motion for Summary Judgment for this lawsuit was granted. Ashland appealed the ruling on July 20, 2017. On January 31, 2018, the Delaware Supreme Court affirmed the lower court’s grant of the Company’s Motion for Summary Judgment. Ashland did not request a rehearing of the ruling. Therefore, the judgment in the Company’s favor is final and this matter is closed. The Company does not currently have any environmental or remediation reserves for matters covered under the ADA Purchase Agreement.

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 any 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 DTSC that an 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.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

For all periods, the Company computed the provision for income taxes based on the actual year-to-date effective tax rate by applying the discrete method.  Use of 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.

The Tax Act significantly revises future U.S. corporate income taxes by, among other things, lowering U.S. corporate income tax rates and implementing a modified territorial tax system. Because the Company has a September 30 fiscal year end, the lower corporate income tax rate will be phased in, resulting in a U.S. statutory federal rate of approximately 24.3% for the Company’s fiscal year ending September 30, 2018 and 21.0% for subsequent fiscal years. The Tax Act also provided for certain transition impacts. As part of the transition to the new modified territorial tax system, the Tax Act imposes a one-time repatriation tax on deemed repatriation of historical earnings of foreign subsidiaries. The Company does not currently anticipate an impact from the repatriation tax charge.

For the six months ended March 31, 2018, the impact of the Tax Act resulted in a net tax benefit of approximately $4.5 million, related solely to the remeasurement of the Company’s net deferred tax liabilities at the lower enacted corporate tax rates.

In accordance with recently issued SEC guidance, the estimated net income tax benefit of $4.5 million is considered provisional representing the Company’s current best estimate based on interpretation of the provisions of the Tax Act, as data continues to be accumulated in order to finalize the underlying calculations. In addition, due to the broad and complex changes contained in the Tax Act, the Company’s current estimate of the impact may be influenced by, among other things, changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act and any changes in accounting standards for income taxes or related interpretations issued in response to the Tax Act. The Company anticipates finalizing and recording any resulting adjustments by the end of its current fiscal year ending September 30, 2018.

Income tax expense for the three months ended March 31, 2018 was $4.6 million on pre-tax income of $5.0 million compared to the income tax expense of $0.8 million on pre-tax loss of $0.3 million for the three months ended March 31, 2017. The current and prior period tax expense was largely attributable to income in profitable foreign jurisdictions.

Income tax expense for the six months ended March 31, 2018 was $5.9 million on pre-tax income of $32.8 million compared to the income tax benefit of $1.9 million on pre-tax loss of $11.3 million for the six months ended March 31, 2017. The current period tax expense was largely attributable to current year income. The expense generated in the U.S. was offset by a current period benefit on deferred tax liabilities as a result of the impact of the Tax Act. The prior period tax benefit was largely attributed to U.S. operations related to deferred taxes driven by the net loss incurred during the period.

At March 31, 2018 and September 30, 2017, the valuation allowance was $2.6 million and $3.1 million, respectively, primarily related to operations in Asia. 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, 2018, management believes it is more likely than not that it will realize the majority of its deferred tax assets.

Uncertain Tax Positions

In connection with the Ultra Chem Acquisition, the Company recorded income tax-related uncertainties totaling $1.4 million, inclusive of interest and penalties. Additionally, the Company also recognized indemnification assets related to certain of these income tax-related uncertainties. The indemnification assets were included in Other current assets and Other non-current assets in the condensed consolidated balance sheets, representing the reimbursement the Company reasonably expected to receive from funds held in escrow pursuant to the purchase agreement.  See Note 3.

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 all periods. The Company had $1.5 million and $1.8 million related to uncertain tax positions, including related accrued interest and penalties as of March 31, 2018 and September 30, 2017, respectively. Between the time of the initial recording of the uncertain tax provisions associated with the Ultra Chem Acquisition and the three months ended March 31, 2018, the Company reduced the reserve by approximately $0.4 million due to the lapse of the applicable statute of limitations.

Segment Reporting [Abstract]

Segment and Geographic Data

Segment and Geographic Data

The Company operates through three lines of business, or operating segments: Chemicals, Plastics and Environmental Services, which market to different sets of customers operating in an array of industries, with various end markets and customer segments within those industries. For segment presentation and disclosure purposes, the Chemicals and Plastics lines of business constitute separate reportable segments, while the Environmental Services line of business, which does not meet the materiality threshold for separate disclosure, is included 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 services and supply, technical support, price and delivery capabilities. 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 and Plastics lines of business are distribution businesses, while the Environmental Services line of business provides hazardous and non-hazardous waste collection, recovery, recycling and disposal services.

A brief description of each segment follows:

Chemicals. The Chemicals line of business distributes specialty and industrial chemicals, additives and solvents to industrial users via railcars, barges, bulk tanker trucks and as packaged goods in trucks. The Company’s chemical products are distributed in more than 50 countries worldwide, primarily in North America and Asia. In connection with the distribution of chemicals products, the Company provides value-added services such as custom blending, packaging and re-packaging, private-label manufacturing and product testing in the form of chemical analysis, product performance analysis and product development. While the Chemicals line of business serves multiple end markets, key end markets within the industrial space are household, industrial and institutional, performance coatings (including architectural coatings, adhesives, sealants and elastomers), lubricants, oil and gas and personal care.

Plastics. The Plastics line of business distributes a broad product line consisting of commodity polymer products and prime engineering resins to plastics processors engaged in blow molding, extrusion, injection molding and rotation molding via railcars, bulk trucks, truckload boxes and mixed truckloads or less-than-truckload quantities. The Company's plastics products are distributed in more than 50 countries worldwide, primarily in North America, EMEA and Asia. While the Plastics line of business serves a broad cross section of industrial segments; key end markets are automotive and healthcare.

Other. The Environmental Services line of business, in connection with certain waste disposal service companies, provides customers with comprehensive on-site and off-site hazardous and non-hazardous waste collection, transportation, recovery, disposal arrangement, and recycling 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 and through a staff of dedicated on-site waste professionals. The Environmental Services line of business serves multiple end markets such as aerospace and defense, automotive, chemical manufacturing, industrial manufacturing and oil and gas.

The Chief Executive Officer is the Chief Operating Decision Maker. The Chief Operating Decision Maker reviews operating results 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 Chief Operating Decision Maker in evaluating line of business performance. These expenses include depreciation and amortization, selling, general and administrative expense and corporate items including 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% of revenues for any line of business for each of the periods reported. Intersegment revenues were insignificant.

Certain assets are aggregated at the line of business level. The assets attributable to the Company’s lines of business, that are reviewed by the Chief Operating Decision Maker, 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, as well as property, plant and equipment, are generally not allocated to a line of business and are included in unallocated assets.

Summarized financial information relating to the Company’s lines of business is as follows:

Recent Accounting Pronouncements Adopted and New Accounting Pronouncements Not Yet Adopted

Recent Accounting Pronouncements Adopted

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. The amendments in this ASU require an entity to measure inventory at the lower of cost or net realizable value, whereas guidance previously required an assessment of market value of inventory, with different possibilities for determining market value. This ASU is effective for fiscal years beginning after December 15, 2016 and interim periods within those years and early adoption is permitted. The Company adopted this standard as of October 1, 2017, and it did not have a material effect on the Company’s financial position or results of operations.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The updated guidance simplifies several aspects of accounting for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as the classification of related matters in the statement of cash flows. This ASU is effective for annual reporting periods beginning after December 15, 2016 and interim periods within those annual periods. The Company adopted this standard as of October 1, 2017 and it did not have a material effect on the Company’s financial position or results of operations.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): This ASU clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as a modified award. The new guidance will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications.  The amendments in this ASU will be applied prospectively to awards modified on or after the adoption date. The Company adopted this standard as of October 1, 2017 and it did not have a material effect on the Company’s financial position or results of operations.

New Accounting Pronouncements Not Yet Adopted

The Company continues the evaluation of the potential effects on its financial position or results of operations of the accounting pronouncements disclosed in its consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2017 filed with the SEC on December 7, 2017, including ASU 2014-09, Revenue from Contracts with Customers and ASU 2016-02, Leases. With regards to ASU 2014-09, the Company continues to work on the identification, design and implementation of changes to its accounting systems, policies and internal controls to support the recognition and disclosure requirements under the new revenue recognition standard. However, the Company does not anticipate the adoption of the guidance will have a material effect on the amount or the timing of revenue recognition associated with the majority of its customer contracts given their general terms and duration. The Company expects to utilize the modified retrospective method of adoption by recognizing the cumulative effect of the adoption change as an adjustment to beginning of period retained earnings for the first quarter of fiscal 2019.

The Company is in the process of evaluating the potential effects of ASU 2016-02 and is formulating its implementation plan, including potential changes to accounting systems, policies and internal controls to support the adoption of the new guidance.
