Basis of Presentation

The condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for the quarterly period ended December 31, 2018 (“Quarterly Report”) include all revenues, costs, assets and liabilities directly attributable to CSWI and have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”).

The condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of CSWI’s financial position as of December 31, 2018, and the results of operations for the three and nine month periods ended December 31, 2018 and 2017. All adjustments are of a normal, recurring nature. All significant intercompany balances and transactions have been eliminated in consolidation. Where applicable, prior period information has been updated to conform to current year presentation.

The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in CSWI’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018 (the “Annual Report”).

Discontinued Operations

During the fiscal quarter ended December 31, 2017, we committed to a plan to divest our Strathmore Products business (the "Coatings business"). This determination resulted in the reclassification of the assets and liabilities comprising that business to assets held-for-sale, and a corresponding adjustment to our condensed consolidated statements of income to reflect discontinued operations for all periods presented. Refer to Note 2 for additional information.

Restructuring

During the fiscal year ended March 31, 2017, we initiated a restructuring program related to our Industrial Products segment. The program was initiated in response to excess capacity, which caused us to perform a facility rationalization analysis. The restructuring program was completed in the fiscal year ended March 31, 2018, and no additional costs are expected to be incurred in connection with it. We incurred other restructuring costs in the fiscal years ended March 31, 2018 and 2017, which are now presented as part of discontinued operations. Restructuring charges are as follows (in thousands):

a. Other consisted of moving costs related to relocation of manufacturing activities, recruiting fees to increase staff in locations where production was relocated and duplicate and inefficient labor costs incurred during the transition and relocation. The charges were expensed as incurred.

Accounting Policies

We have consistently applied the accounting policies described in our Annual Report in preparing these condensed consolidated financial statements. We have not made any changes in significant accounting policies disclosed in the Annual Report, with the exception of the revenue recognition policy described below as a result of adopting Accounting Standards Update ("ASU") No. 2014-09.

Revenue Recognition – We recognize revenues to depict the transfer of control of promised goods or services to our customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Refer to Note 16 for further discussion. We recognize revenue when all of the following criteria have been met: (i) a contract with a customer exists, (ii) performance obligations have been identified, (iii) the price to the customer has been determined, (iv) the price to the customer has been allocated to the performance obligations, and (v) performance obligations are satisfied, which are more fully described below.

(i) We identify a contract with a customer when a sales agreement indicates approval and commitment of the parties; identifies the rights of the parties; identifies the payment terms; has commercial substance; and it is probable that we will collect the consideration to which we will be entitled in exchange for the goods or services that will be transferred to the customer. In most instances, our contract with a customer is the customer's purchase order. For certain customers, we may also enter into a sales agreement that outlines a framework of terms and conditions that apply to all future purchase orders for that customer. In these situations, our contract with the customer is both the sales agreement and the specific customer purchase order. Because our contract with a customer is typically for a single transaction or customer purchase order, the duration of the contract is one year or less. As a result, we have elected to apply certain practical expedients and, as permitted by the Financial Accounting Standards Board ("FASB"), omit certain disclosures of remaining performance obligations for contracts that have an initial term of one year or less.

(ii) We identify performance obligations in a contract for each promised good or service that is separately identifiable from other promises in the contract and for which the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer. Goods and services provided to our customers that are deemed immaterial are included with other performance obligations.

(iii) We determine the transaction price as the amount of consideration we expect to be entitled to in exchange for fulfilling the performance obligations, including the effects of any variable consideration.

(iv) For any contracts that have more than one performance obligation, we allocate the transaction price to each performance obligation in an amount that depicts the amount of consideration to which we expect to be entitled in exchange for satisfying each performance obligation. We have excluded disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less as the majority of our contracts are short-term in nature with a term of one year or less.

(v) We recognize revenue when, or as, we satisfy the performance obligation in a contract by transferring control of a promised good or service to the customer.

We exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected from a customer. As such, we present

revenue net of sales and other similar taxes. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of revenues. Costs to obtain a contract, which include sales commissions recorded in selling, general and administrative expense, are expensed when incurred as the amortization period is one year or less. We do not have customer contracts that include significant financing components.

Accounting Developments

Pronouncements Implemented

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," which was subsequently amended with additional ASUs including ASU No. 2016-12, issued in May 2016, and ASU No. 2016-20, issued in December 2016. ASU No. 2014-09, as amended, supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)." The standard is principle-based and provides a five-step model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. On April 1, 2018, we adopted the new revenue standard using the modified retrospective method for transition, applying the guidance to those contracts that were not completed as of that date. In accordance with our method of transition, we calculated the cumulative effect of the changes made to our condensed consolidated balance sheet and recorded a cumulative effect adjustment to decrease retained earnings by $0.7 million, mostly associated with transition of contracts with revenue previously recognized under the percentage of completion ("POC") method of revenue recognition. We have modified our accounting policies to support compliance with the standard requirements. Revenue recognition and related financial information for this Quarterly Report are based on the requirements of Accounting Standards Codification ("ASC") Topic 606. Accordingly, periods prior to April 1, 2018 are presented in accordance with ASC Topic 605. Refer to Note 16 for a discussion of our adoption of ASC Topic 606.

In August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments," which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows and how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. We adopted this standard effective April 1, 2018. This standard did not have an impact on our consolidated statement of cash flows as cash receipts and payments presented do not have aspects of more than one class of cash flows.

In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory," to improve the accounting for the income tax consequences arising from these types of transfers. This ASU aligns the recognition of the income tax consequences with International Financial Reporting Standards. Specifically, International Accounting Standards No. 12, "Income Taxes," requires recognition of current and deferred income taxes resulting from an intra-entity transfer of any asset (excluding inventory) when the transfer occurs. We adopted this standard effective April 1, 2018. The resulting impact was a reduction of opening retained earnings of 1.2 million.

In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)," which requires that amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. We adopted this standard effective April 1, 2018. This standard did not have an impact on our consolidated statement of cash flows as we do not have any restricted cash or restricted cash equivalents for any period presented.

In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business," to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this ASU require that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set of assets is not a business. We adopted this standard effective April 1, 2018. This standard did not have an impact on our financial position or results of operations as we did not have any acquisitions or dispositions during the nine months ended December 31, 2018 for which we applied this guidance.

In March 2017, the FASB issued ASU No. 2017-07, "Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which requires that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments also provide explicit

guidance on how to present the service cost component and the other components of net benefit cost in the statement of income and allow only the service cost component of net benefit cost to be eligible for capitalization. We adopted this standard effective April 1, 2018 on a retrospective basis. The adoption of this ASU had no impact on our financial condition or results of operations, except for reclassification of costs within the condensed consolidated income statement. Refer to Note 12 for details of the impact of the adoption of this ASU.

On December 22, 2017, the President of the U.S. signed new tax legislation, commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act significantly changed U.S. income tax law, including a reduction of the corporate income tax rate to 21%, creation of a territorial tax system (with a one-time mandatory tax on previously deferred foreign earnings), broadened the tax base and allowed for immediate capital expensing of certain qualified property. It also requires companies to pay minimum taxes on foreign earnings and subjects certain payments from corporations to foreign related parties to additional taxes. ASC 740, “Accounting for Income Taxes,” requires companies to recognize the effect of tax law changes in the period of enactment even though the effective date for most provisions is for tax years beginning after December 31, 2017, or in the case of certain other provisions, January 1, 2018. Certain key aspects of the new law were effective January 1, 2018 and were accounted for during the fiscal year ended March 31, 2018. Other significant provisions became effective April 1, 2018 for March 31 fiscal year end entities, and will be accounted for in the fiscal year ending March 31, 2019. Some of the changes effective for the year ending March 31, 2019 include the deduction for executive compensation and interest expense, a tax on global intangible low-taxed provisions ("GILTI"), and a deduction for foreign-derived intangible income ("FDII").

The Securities and Exchange Commission ("SEC") staff issued Staff Accounting Bulletin ("SAB") 118 to provide guidance for companies that were not able to complete their accounting for the income tax effects of the Tax Act in the period of enactment. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company's accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate to be included in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. In accordance with SAB 118, we recorded provisional amounts reflecting the impact of the Tax Act in our consolidated financial statements and related disclosures as of March 31, 2018. As of March 31, 2018, we recorded an estimate of $1.9 million related to the deemed repatriation provision of the Tax Act. During the quarter ended December 31, 2018, we recorded additional expense of $0.5 million related to the deemed repatriation provision of the Tax Act as the deemed repatriation calculation was finalized in connection with the filing of our federal tax return. With the finalization of the deemed repatriation calculation and the expiration of the measurement period under SAB 118 during the quarter ended December 31, 2018, our accounting for the income tax effects of the Tax Act for the period of enactment is now complete.

The Tax Act subjects us to GILTI earned by certain of our foreign subsidiaries. In general, this income will effectively be taxed at a 10.5% tax rate reduced by any available current year foreign tax credits. This provision was effective for taxable years beginning after December 31, 2017. Under U.S. GAAP, we are allowed to make an accounting policy election of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the "period cost method") or (2) factoring such amounts into measurement of our deferred taxes (the "deferred method"). We have adopted the period cost method and will treat the inclusion of GILTI as current period expense when incurred. We recorded tax expense of $0.7 million excluding credits related to GILTI tax related to current year operations in our estimated annual effective tax rate.

The Tax Act allows a domestic corporation an immediate deduction in U.S. taxable income for a portion of its FDII. The amount of the deduction will depend in part on our U.S. taxable income. The FDII deduction will be available for the current fiscal year ending March 31, 2019. We have recorded a $0.3 million tax benefit for the FDII deduction related to the current year operations in our estimated annual effective tax rate.

Pronouncements not yet implemented

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," which has been subsequently amended with additional ASUs including ASU No. 2018-10 and ASU No. 2018-11 issued in July 2018 and ASU No. 2018-20 issued in December 2018, to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. The recognition, measurement, and presentation of expenses and cash flows

arising from a lease by a lessee have not significantly changed from previous U.S. GAAP. This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. Modified retrospective application is permitted with certain practical expedients. Early adoption is permitted. We continue to evaluate critical components of this new guidance and the potential impact that the guidance will have on our financial position, results of operations and cash flows, which includes review of our leasing contracts and implementation of our selected software tool. The impact of adoption on our financial position, results of operations and cash flows will be available when the software implementation is complete.

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments," as amended by ASU No. 2018-19, which requires, among other things, the use of a new current expected credit loss ("CECL") model in order to determine our allowances for doubtful accounts with respect to accounts receivable. The CECL model requires that we estimate our lifetime expected credit loss with respect to our receivables and contract assets and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. We will also be required to disclose information about how we developed the allowances, including changes in the factors that influenced our estimate of expected credit losses and the reasons for those changes. This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. We are currently evaluating the impact of this ASU on our consolidated financial condition and results of operations.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," which modifies the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. The amendments in this ASU should be adopted for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of ASU No. 2017-04 will only impact our consolidated financial condition and results of operations to the extent that we incur a future goodwill impairment.

In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted improvements of Accounting for Hedging Activities." The purpose of this ASU is to better align a company's risk management activities and financial reporting for hedging relationships. Additionally, the ASU simplifies the hedge accounting requirements and improve the disclosures of hedging arrangements. This ASU was amended by ASU 2018-16 to include the secured overnight financing rate as an acceptable reference rate. This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. We do not expect adoption of this ASU to have a material impact on our consolidated financial condition or results of operations.

In February 2018, the FASB issued ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." The amendments in this ASU allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. Consequently, the amendments eliminate the stranded tax effects resulting from the Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The amendments in this ASU also require certain disclosures about stranded tax effects. This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. We are currently evaluating the impact of this ASU on our consolidated financial condition and results of operations.

In August 2018, the FASB issued ASU No. 2018-13, "Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement," which modifies the disclosure requirements on fair value measurements. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. An entity is permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until their effective date. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. We do not expect adoption of this ASU to have a material impact on our consolidated financial condition and results of operations.

In August 2018, the FASB issued ASU No. 2018-14, "Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans," which modifies the disclosure requirements for employers that sponsor defined benefit pension or

other postretirement plans. The amendments remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures and add disclosure requirements identified as relevant. This ASU is effective, on a retrospective basis, for fiscal years ending after December 15, 2020. Early adoption is permitted. We do not expect adoption of this ASU to have a material impact on our consolidated financial condition and results of operations.

In August 2018, the FASB issued ASU No. 2018-15, "Customer's Accounting for the Implementation Costs Incurred in Cloud Computing Arrangement That is a Service Contract." The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, and should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Early adoption is permitted. We do not expect adoption of this ASU to have a material impact on our consolidated financial condition and results of operations.

Discontinued Operations and Disposal Groups [Abstract]

DISCONTINUED OPERATIONS

During the quarter ended December 31, 2017, we commenced a sale process to divest our Coatings business to allow us to focus resources on our core growth platforms. Our Coatings business manufactured specialized industrial coating products including urethanes, epoxies, acrylics and alkyds. The Coatings business met the held-for-sale criteria under ASC 360, "Property, Plant and Equipment," and accordingly, we classified and accounted for the assets and liabilities of the Coatings business as held-for-sale in the accompanying condensed consolidated balance sheets, and as discontinued operations, net of tax, in the accompanying condensed consolidated statements of income and cash flows. We estimated that the fair value of the business was less than carrying value at December 31, 2017, resulting in a $46.0 million impairment charge. We completed an initial assessment of the assets and liabilities of the Coatings business and recorded the impairment based on our best estimates as of the date of issuance of financial results for the quarter ended December 31, 2017.

On July 31, 2018, we consummated a sale of assets related to our Coatings business to an unrelated third party, the terms of which were not disclosed due to immateriality. During the three months ended September 30, 2018, we received an aggregate of $6.9 million for the sale of assets that related to our Coatings business in multiple transactions. This resulted in gains on disposal of $6.9 million due to write-downs of long-lived assets in prior periods.

Summarized selected financial information for the Coatings business for the three and nine months ended December 31, 2018 and 2017, is presented in the following table:

(a) The assets and liabilities of the Coatings business reside in a disregarded entity for tax purposes. Accordingly, the tax attributes associated with the operations of our Coatings business will ultimately flow through to the corporate parent, which files a consolidated federal return. Therefore, any corresponding tax assets or liabilities have been reflected as a component of our continuing operations.

During the restriction period, the holders of restricted shares are entitled to vote and, except for conversion awards issued under the Spin-Off Executive Compensation Plan (as discussed in Note 5 to our consolidated financial statements included in our Annual Report), receive dividends. Unvested restricted shares outstanding as of December 31, 2018 and March 31, 2018 included 96,282 and 82,800 shares (at target), respectively, with performance-based vesting provisions, and vesting ranges from 0%-200% based on pre-defined performance targets with market conditions. Performance-based awards do not provide for the rights to vote or receive cash dividends until vesting. Performance-based awards are earned upon the achievement of objective performance targets, and are payable in common shares. Compensation expense is calculated based on the fair market value as determined by a Monte Carlo simulation and is recognized over a 36-month cliff vesting period.

At December 31, 2018, we had unrecognized compensation cost related to unvested restricted shares of $6.9 million, which will be amortized into net income over the remaining weighted average vesting period of approximately 2.0 years. The total fair value of restricted shares granted during the three months ended December 31, 2018 and 2017 was $3.3 million and $3.5 million, respectively.

Revolving Credit Facility

As discussed in Note 8 to our consolidated financial statements included in our Annual Report, we have a five-year, $250.0 million revolving credit facility agreement, with an additional $50.0 million accordion feature, which matures on September 15, 2022 (the “Revolving Credit Facility”). Borrowings under this facility bear interest at a rate of prime plus 0.25% or London Interbank Offered Rate ("LIBOR") plus 1.25%, which may be adjusted based on our leverage ratio. We pay a commitment fee of 0.15% for the unutilized portion of the Revolving Credit Facility. Interest and commitment fees are payable at least quarterly and the outstanding principal balance is due at the maturity date. The Revolving Credit Facility is secured by substantially all of our domestic assets. During the nine months ended December 31, 2018, we borrowed $8.0 million and repaid $20.0 million under this facility, and as of December 31, 2018 and March 31, 2018, we had a remaining outstanding balance of $0 and $12.0 million, respectively, which resulted in borrowing capacity of $300.0 million and $288.0 million, respectively, inclusive of the accordion feature. Covenant compliance is tested quarterly, and we were in compliance with all covenants as of December 31, 2018.

Whitmore Term Loan

As of December 31, 2018, Whitmore Manufacturing (one of our wholly-owned operating subsidiaries) had a secured term loan ("Whitmore Term Loan") outstanding related to a warehouse and corporate office building and the remodel of an existing manufacturing and research and development facility. The Whitmore Term Loan matures on July 31, 2029 and requires payments of $140,000 due each quarter. Borrowings under this term loan bear interest at a variable annual rate equal to one month LIBOR plus 2.0%. As of December 31, 2018 and March 31, 2018, Whitmore Manufacturing had $11.6 million and $12.0 million, respectively, in outstanding borrowings under the term loan. Interest payments under the Whitmore Term Loan are hedged under an interest rate swap agreement as described in Note 8.

DERIVATIVE INSTRUMENTS AND HEDGE ACCOUNTING

We have an interest rate swap agreement to hedge exposure to floating interest rates on a certain portion of our debt. As of December 31, 2018 and March 31, 2018, we had $11.6 million and $12.0 million, respectively, of notional amount outstanding designated as an interest rate swap with third parties. The interest rate swap is highly effective. At December 31, 2018, the maximum remaining length of the interest rate swap contract was approximately 11 years.

We repurchased 57,499 and 629,659 shares of our common stock under this program during the three and nine months ended December 31, 2018, respectively, for an aggregate amount of $3.0 million and $33.8 million, respectively. As of October 31, 2018, a total of 656,203 shares had been repurchased for an aggregate amount of $35.0 million, and the program was completed. On November 7, 2018, we announced that our Board of Directors authorized a new program to repurchase up to $75.0 million of our common stock over a two-year time period. These shares may be repurchased from time to time in the open market or in privately negotiated transactions. Repurchases will be made from time to time at our discretion, based on ongoing assessments of the capital needs of the business, the market price of our common stock and general market conditions. The program may be limited or terminated at any time at our discretion without notice. We repurchased 136,212 shares under the new program during the three months ended December 31, 2018 for an aggregate amount of $6.9 million.

FAIR VALUE MEASUREMENTS	9 Months Ended
FAIR VALUE MEASUREMENTS	Dec. 31, 2018
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTSThe fair value of the interest rate swap contract (as discussed in Note 8) is determined using Level 2 inputs. The carrying value of our debt (discussed in Note 7) approximates fair value as it bears interest at floating rates. The carrying amounts of other financial instruments (i.e., cash and cash equivalents, accounts receivable, net, accounts payable) approximate their fair values at December 31, 2018 and March 31, 2018 due to their short-term nature.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Retirement Benefits [Abstract]

RETIREMENT PLANS

Refer to Note 13 to our consolidated financial statements included in our Annual Report for a description of our retirement and post-retirement benefits.

As disclosed in Note 1, we adopted ASU No. 2017-07, effective April 1, 2018 on a retrospective basis. The resulting impact on the condensed consolidated income statements of reclassifying the impact of non-service component costs to other income, net for the three and nine months ended December 31, 2017 was an immaterial reduction in cost of revenues, an increase in selling, general and administrative expenses of $0.3 million and $1.0 million, respectively, and a decrease in other income, net of $0.3 million and $1.0 million, respectively.

The following tables set forth the combined net pension benefit recognized in our condensed consolidated financial statements for all plans (in thousands):


	Three Months Ended December 31,						Nine Months Ended December 31,

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES For the three months ended December 31, 2018, we earned $9.5 million from continuing operations before taxes and provided for income taxes of $3.5 million, resulting in an effective tax rate of 36.7%. For the nine months ended December 31, 2018, we earned $44.4 million from continuing operations before taxes and provided for income taxes of $12.0 million, resulting in an effective tax rate of 27.0%. The provision for income taxes differed from the statutory rate for the three and nine months ended December 31, 2018 primarily due to adjustments related to federal and foreign income tax returns. For the three months ended December 31, 2017, we earned $7.8 million from continuing operations before taxes and provided for income taxes of $5.1 million, resulting in an effective tax rate of 66.1%. For the nine months ended December 31, 2017, we earned $38.3 million from continuing operations before taxes and provided for income taxes of $16.2 million, resulting in an effective tax rate of 42.4%. The provision for income taxes differed from the statutory rate for the three and nine months ended December 31, 2017 primarily due to the one-time mandatory repatriation tax under the new tax legislation. We are currently under audit for our U.S. federal income tax returns for the fiscal years ended March 31, 2017 and 2016. We have not been notified of any potential adjustments.

REVENUE RECOGNITION

Revenue from Contract with Customer [Abstract]

REVENUE RECOGNITION

We adopted the guidance included in ASC Topic 606 as described in Note 1, effective April 1, 2018 using the modified retrospective approach and applied the new guidance to all open contracts at the date of adoption. Adoption of the new standard is reflected in the accounting policy (as discussed in Note 1) and disclosures related to revenue recognition. Our revenue recognition methodology does not materially change following the adoption of the new guidance as the majority of our annual revenue is derived from point in time sales. We recorded a decrease to opening retained earnings, net of tax, of $0.7 million due to the adoption of ASC Topic 606. Additionally, inventory and accrued other current liabilities increased $2.1 million as billings under the POC method were reclassified out of inventory into deferred revenue. The adoption of ASC Topic 606 has had no material impact on current year revenues.

Disaggregation of Revenue

As disclosed in our Annual Report, we conduct our operations in two reportable segments: Industrial Products and Specialty Chemicals. With the adoption of ASC Topic 606, we have concluded that the disaggregation of revenues that would be most useful in understanding the nature, timing and extent of revenue recognition is the breakout of build-to-order and book-and-ship, as defined below:

Build-to-order products are architecturally-specified building products generally sold into the construction industry. Revenue generated from sales of products under build-to-order transactions are currently reflected in the results of our Industrial Products Segment. Occasionally, our built-to-order business lines enter into arrangements for the delivery of a customer-specified product and the provision of installation services. These orders are generally negotiated as a package and are commonly subject to retainage by the customer, which means the final 10% of the transaction price, when applicable, is not collectible until the overall construction project into which our products are incorporated is complete. The lead times for transfer to the customer can be up to 12 weeks. Revenue for goods is recognized at a point in time, but installation services are recognized over time as those services are performed. Installation services represented approximately 1% of total consolidated revenue for each of the three and nine months ended December 31, 2018.

Book-and-ship products are sold across all of our end markets. Revenue generated from sales of products under book-and-ship transactions have historically been presented in both Industrial Products and Specialty Chemicals. These sales are typically priced on a product-by-product basis using price lists provided to our customers. The lead times for transfer to the customer is usually one week or less as these items are generally built to stock. Revenue for products sold under these arrangements is recognized at a point in time.

Disaggregation of revenues reconciled to our reportable segments is as follows (in thousands):

ORGANIZATION AND OPERATIONS AND SUMMARY OF ACCOUNTING POLICIES (Policies)	9 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for the quarterly period ended December 31, 2018 (“Quarterly Report”) include all revenues, costs, assets and liabilities directly attributable to CSWI and have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”). The condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of CSWI’s financial position as of December 31, 2018, and the results of operations for the three and nine month periods ended December 31, 2018 and 2017. All adjustments are of a normal, recurring nature. All significant intercompany balances and transactions have been eliminated in consolidation. Where applicable, prior period information has been updated to conform to current year presentation. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in CSWI’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018 (the “Annual Report”).
Discontinued Operations	Discontinued Operations During the fiscal quarter ended December 31, 2017, we committed to a plan to divest our Strathmore Products business (the "Coatings business"). This determination resulted in the reclassification of the assets and liabilities comprising that business to assets held-for-sale, and a corresponding adjustment to our condensed consolidated statements of income to reflect discontinued operations for all periods presented. Refer to Note 2 for additional information.
Revenue Recognition	Revenue Recognition – We recognize revenues to depict the transfer of control of promised goods or services to our customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Refer to Note 16 for further discussion. We recognize revenue when all of the following criteria have been met: (i) a contract with a customer exists, (ii) performance obligations have been identified, (iii) the price to the customer has been determined, (iv) the price to the customer has been allocated to the performance obligations, and (v) performance obligations are satisfied, which are more fully described below. (i) We identify a contract with a customer when a sales agreement indicates approval and commitment of the parties; identifies the rights of the parties; identifies the payment terms; has commercial substance; and it is probable that we will collect the consideration to which we will be entitled in exchange for the goods or services that will be transferred to the customer. In most instances, our contract with a customer is the customer's purchase order. For certain customers, we may also enter into a sales agreement that outlines a framework of terms and conditions that apply to all future purchase orders for that customer. In these situations, our contract with the customer is both the sales agreement and the specific customer purchase order. Because our contract with a customer is typically for a single transaction or customer purchase order, the duration of the contract is one year or less. As a result, we have elected to apply certain practical expedients and, as permitted by the Financial Accounting Standards Board ("FASB"), omit certain disclosures of remaining performance obligations for contracts that have an initial term of one year or less. (ii) We identify performance obligations in a contract for each promised good or service that is separately identifiable from other promises in the contract and for which the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer. Goods and services provided to our customers that are deemed immaterial are included with other performance obligations. (iii) We determine the transaction price as the amount of consideration we expect to be entitled to in exchange for fulfilling the performance obligations, including the effects of any variable consideration. (iv) For any contracts that have more than one performance obligation, we allocate the transaction price to each performance obligation in an amount that depicts the amount of consideration to which we expect to be entitled in exchange for satisfying each performance obligation. We have excluded disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less as the majority of our contracts are short-term in nature with a term of one year or less. (v) We recognize revenue when, or as, we satisfy the performance obligation in a contract by transferring control of a promised good or service to the customer. We exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected from a customer. As such, we present revenue net of sales and other similar taxes. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of revenues. Costs to obtain a contract, which include sales commissions recorded in selling, general and administrative expense, are expensed when incurred as the amortization period is one year or less. We do not have customer contracts that include significant financing components.
Accounting Developments	Accounting Developments Pronouncements Implemented In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," which was subsequently amended with additional ASUs including ASU No. 2016-12, issued in May 2016, and ASU No. 2016-20, issued in December 2016. ASU No. 2014-09, as amended, supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)." The standard is principle-based and provides a five-step model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. On April 1, 2018, we adopted the new revenue standard using the modified retrospective method for transition, applying the guidance to those contracts that were not completed as of that date. In accordance with our method of transition, we calculated the cumulative effect of the changes made to our condensed consolidated balance sheet and recorded a cumulative effect adjustment to decrease retained earnings by $0.7 million, mostly associated with transition of contracts with revenue previously recognized under the percentage of completion ("POC") method of revenue recognition. We have modified our accounting policies to support compliance with the standard requirements. Revenue recognition and related financial information for this Quarterly Report are based on the requirements of Accounting Standards Codification ("ASC") Topic 606. Accordingly, periods prior to April 1, 2018 are presented in accordance with ASC Topic 605. Refer to Note 16 for a discussion of our adoption of ASC Topic 606. In August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments," which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows and how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. We adopted this standard effective April 1, 2018. This standard did not have an impact on our consolidated statement of cash flows as cash receipts and payments presented do not have aspects of more than one class of cash flows. In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory," to improve the accounting for the income tax consequences arising from these types of transfers. This ASU aligns the recognition of the income tax consequences with International Financial Reporting Standards. Specifically, International Accounting Standards No. 12, "Income Taxes," requires recognition of current and deferred income taxes resulting from an intra-entity transfer of any asset (excluding inventory) when the transfer occurs. We adopted this standard effective April 1, 2018. The resulting impact was a reduction of opening retained earnings of 1.2 million. In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)," which requires that amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. We adopted this standard effective April 1, 2018. This standard did not have an impact on our consolidated statement of cash flows as we do not have any restricted cash or restricted cash equivalents for any period presented. In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business," to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this ASU require that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set of assets is not a business. We adopted this standard effective April 1, 2018. This standard did not have an impact on our financial position or results of operations as we did not have any acquisitions or dispositions during the nine months ended December 31, 2018 for which we applied this guidance. In March 2017, the FASB issued ASU No. 2017-07, "Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which requires that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost in the statement of income and allow only the service cost component of net benefit cost to be eligible for capitalization. We adopted this standard effective April 1, 2018 on a retrospective basis. The adoption of this ASU had no impact on our financial condition or results of operations, except for reclassification of costs within the condensed consolidated income statement. Refer to Note 12 for details of the impact of the adoption of this ASU. On December 22, 2017, the President of the U.S. signed new tax legislation, commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act significantly changed U.S. income tax law, including a reduction of the corporate income tax rate to 21%, creation of a territorial tax system (with a one-time mandatory tax on previously deferred foreign earnings), broadened the tax base and allowed for immediate capital expensing of certain qualified property. It also requires companies to pay minimum taxes on foreign earnings and subjects certain payments from corporations to foreign related parties to additional taxes. ASC 740, “Accounting for Income Taxes,” requires companies to recognize the effect of tax law changes in the period of enactment even though the effective date for most provisions is for tax years beginning after December 31, 2017, or in the case of certain other provisions, January 1, 2018. Certain key aspects of the new law were effective January 1, 2018 and were accounted for during the fiscal year ended March 31, 2018. Other significant provisions became effective April 1, 2018 for March 31 fiscal year end entities, and will be accounted for in the fiscal year ending March 31, 2019. Some of the changes effective for the year ending March 31, 2019 include the deduction for executive compensation and interest expense, a tax on global intangible low-taxed provisions ("GILTI"), and a deduction for foreign-derived intangible income ("FDII"). The Securities and Exchange Commission ("SEC") staff issued Staff Accounting Bulletin ("SAB") 118 to provide guidance for companies that were not able to complete their accounting for the income tax effects of the Tax Act in the period of enactment. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company's accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate to be included in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. In accordance with SAB 118, we recorded provisional amounts reflecting the impact of the Tax Act in our consolidated financial statements and related disclosures as of March 31, 2018. As of March 31, 2018, we recorded an estimate of $1.9 million related to the deemed repatriation provision of the Tax Act. During the quarter ended December 31, 2018, we recorded additional expense of $0.5 million related to the deemed repatriation provision of the Tax Act as the deemed repatriation calculation was finalized in connection with the filing of our federal tax return. With the finalization of the deemed repatriation calculation and the expiration of the measurement period under SAB 118 during the quarter ended December 31, 2018, our accounting for the income tax effects of the Tax Act for the period of enactment is now complete. The Tax Act subjects us to GILTI earned by certain of our foreign subsidiaries. In general, this income will effectively be taxed at a 10.5% tax rate reduced by any available current year foreign tax credits. This provision was effective for taxable years beginning after December 31, 2017. Under U.S. GAAP, we are allowed to make an accounting policy election of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the "period cost method") or (2) factoring such amounts into measurement of our deferred taxes (the "deferred method"). We have adopted the period cost method and will treat the inclusion of GILTI as current period expense when incurred. We recorded tax expense of $0.7 million excluding credits related to GILTI tax related to current year operations in our estimated annual effective tax rate. The Tax Act allows a domestic corporation an immediate deduction in U.S. taxable income for a portion of its FDII. The amount of the deduction will depend in part on our U.S. taxable income. The FDII deduction will be available for the current fiscal year ending March 31, 2019. We have recorded a $0.3 million tax benefit for the FDII deduction related to the current year operations in our estimated annual effective tax rate. Pronouncements not yet implemented In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," which has been subsequently amended with additional ASUs including ASU No. 2018-10 and ASU No. 2018-11 issued in July 2018 and ASU No. 2018-20 issued in December 2018, to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous U.S. GAAP. This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. Modified retrospective application is permitted with certain practical expedients. Early adoption is permitted. We continue to evaluate critical components of this new guidance and the potential impact that the guidance will have on our financial position, results of operations and cash flows, which includes review of our leasing contracts and implementation of our selected software tool. The impact of adoption on our financial position, results of operations and cash flows will be available when the software implementation is complete. In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments," as amended by ASU No. 2018-19, which requires, among other things, the use of a new current expected credit loss ("CECL") model in order to determine our allowances for doubtful accounts with respect to accounts receivable. The CECL model requires that we estimate our lifetime expected credit loss with respect to our receivables and contract assets and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. We will also be required to disclose information about how we developed the allowances, including changes in the factors that influenced our estimate of expected credit losses and the reasons for those changes. This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. We are currently evaluating the impact of this ASU on our consolidated financial condition and results of operations. In January 2017, the FASB issued ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," which modifies the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. The amendments in this ASU should be adopted for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of ASU No. 2017-04 will only impact our consolidated financial condition and results of operations to the extent that we incur a future goodwill impairment. In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted improvements of Accounting for Hedging Activities." The purpose of this ASU is to better align a company's risk management activities and financial reporting for hedging relationships. Additionally, the ASU simplifies the hedge accounting requirements and improve the disclosures of hedging arrangements. This ASU was amended by ASU 2018-16 to include the secured overnight financing rate as an acceptable reference rate. This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. We do not expect adoption of this ASU to have a material impact on our consolidated financial condition or results of operations. In February 2018, the FASB issued ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." The amendments in this ASU allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. Consequently, the amendments eliminate the stranded tax effects resulting from the Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The amendments in this ASU also require certain disclosures about stranded tax effects. This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. We are currently evaluating the impact of this ASU on our consolidated financial condition and results of operations. In August 2018, the FASB issued ASU No. 2018-13, "Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement," which modifies the disclosure requirements on fair value measurements. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. An entity is permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until their effective date. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. We do not expect adoption of this ASU to have a material impact on our consolidated financial condition and results of operations. In August 2018, the FASB issued ASU No. 2018-14, "Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans," which modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The amendments remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures and add disclosure requirements identified as relevant. This ASU is effective, on a retrospective basis, for fiscal years ending after December 15, 2020. Early adoption is permitted. We do not expect adoption of this ASU to have a material impact on our consolidated financial condition and results of operations. In August 2018, the FASB issued ASU No. 2018-15, "Customer's Accounting for the Implementation Costs Incurred in Cloud Computing Arrangement That is a Service Contract." The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, and should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Early adoption is permitted. We do not expect adoption of this ASU to have a material impact on our consolidated financial condition and results of operations.
