NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — CONSOLIDATION, NONCONTROLLING INTERESTS AND BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles in the U.S. (“GAAP”) for interim financial information and the instructions to Form 10-Q. In our opinion, all adjustments (consisting of normal, recurring accruals) considered necessary for a fair presentation have been included for the three and six month periods ended November 30, 2017 and 2016.  For further information, refer to the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended May 31, 2017.

Our financial statements include all of our majority-owned subsidiaries. We account for our investments in less-than-majority-owned joint ventures, for which we have the ability to exercise significant influence, under the equity method.  Effects of transactions between related companies are eliminated in consolidation.

Noncontrolling interests are presented in our consolidated financial statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially-owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in our consolidated financial statements. Additionally, our consolidated financial statements include 100% of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control.

Our business is dependent on external weather factors. Historically, we have experienced strong sales and net income in our first, second and fourth fiscal quarters comprising the three month periods ending August 31, November 30 and May 31, respectively, with weaker performance in our third fiscal quarter (December through February).

NOTE 2 — NEW ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” which establishes a comprehensive revenue recognition standard that will supersede nearly all existing revenue recognition guidance under GAAP. The new standard prescribes a five-step model for recognizing revenue, which will require significant judgment in its application. The new standard requires disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

Under the original issuance, the new standard would have applied to annual periods beginning after December 15, 2016, including interim periods therein. However, in August 2015, the FASB issued ASU 2015-14, which extends the standard effective date by one year and includes an option to apply the standard on the original effective date. The provisions of this ASU may be applied retrospectively to each prior reporting period presented, or on a modified retrospective basis by recognizing a cumulative catch-up transition amount at the date of initial application. We have selected the modified retrospective transition method, which we will apply upon adoption of the standard as of June 1, 2018.

Given the scope of work required to implement the recognition and disclosure requirements under the new standard, we began our assessment process during fiscal 2016.  Our progress to date includes a preliminary identification of areas which will require changes to policies, processes, systems or internal controls.  We expect revenue recognition for our broad portfolio of products and services to remain largely unchanged. However, the guidance is expected to change the timing of revenue recognition in certain areas, including our accounting for long-term construction contracts. While these impacts are not expected to be material to our overall Consolidated Financial Statements, we do anticipate that the new disclosure requirements surrounding revenue recognition will be significant. We continue to assess all potential impacts of the guidance and given the stage of our adoption procedures as well as our normal ongoing business dynamics, our preliminary conclusions and assessments of the potential impacts on each of our different business units’ revenue streams are subject to change.  

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which increases lease transparency and comparability among organizations.  Under the new standard, lessees will be required to recognize all assets and liabilities arising from leases on the balance sheet, with the exception of leases with a term of 12 months or less, which permits a lessee to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities.  ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and early adoption is permitted. The new standard requires the recognition and measurement of leases at the beginning of the earliest period presented using a modified retrospective approach, which includes a number of optional practical expedients that entities may elect to apply.  We are currently evaluating the impact this guidance will have on our Consolidated Financial Statements. At a minimum, total assets and total liabilities will increase in the period the ASU is adopted.  At November 30, 2017, our total undiscounted future minimum payments outstanding for operating lease obligations approximated $214.0 million.

RPM INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which makes a number of changes meant to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows.  The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted.  Upon adoption, entities must apply the guidance retrospectively to all periods presented.  We are currently evaluating the impact this guidance will have on our Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations: Clarifying the Definition of a Business,” with the objective of adding guidance to assist entities in evaluating whether transactions should be accounted for as acquisitions (disposals) of assets or of businesses. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. We are currently reviewing the impact this revised guidance will have on our Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” to eliminate step two from the goodwill impairment test in order to simplify the subsequent measurement of goodwill. The guidance is effective for fiscal years beginning after December 15, 2019. Early application is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Adoption of this guidance is not expected to have a material impact on our Consolidated Financial Statements.  

In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented.  The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years.  We are currently reviewing the impact this guidance will have on our Consolidated Financial Statements.  

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities,” which simplifies hedge accounting through changes to both designation and measurement requirements.  For hedges that qualify as highly effective, the new standard eliminates the requirement to separately measure and record hedge ineffectiveness, resulting in better alignment between the presentation of the effects of the hedging instrument and the hedged item in the financial statements.  ASU No. 2017-12 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  Early adoption is permitted in any interim period after issuance of the update.  Our early adoption of this pronouncement during our current quarter ended November 30, 2017 did not have a material impact on our Consolidated Financial Statements.  Refer to Note 6, “Derivatives and Hedging,” for further information.    

NOTE 3 – GOODWILL AND OTHER INTANGIBLE ASSETS

During the three month period ended November 30, 2016, we recorded impairment charges related to a reduction of the carrying value of goodwill and other intangible assets totaling $188.3 million.  All of the charges were recorded by our consumer reportable segment.  The goodwill impairment loss incurred during fiscal 2017 totaled $140.7 million, and the impairment losses for other intangible assets, totaling $47.8 million, related to formulae for $15.4 million; customer-related intangibles for $30.2 million; other intangibles for $0.2 million and indefinite-lived trademarks for $2.0 million.  

Total accumulated goodwill impairment losses were $156.3 million and $155.6 million at November 30, 2017 and 2016, which comprise the goodwill impairment loss incurred during fiscal 2017 as well as a $14.9 million goodwill impairment loss recorded by our industrial reportable segment during fiscal 2009.

The gross amount of other intangible asset accumulated impairment losses were $53.6 million and $48.4 million at November 30, 2017 and 2016, which comprise the other intangible asset impairment loss of $47.8 million incurred during fiscal 2017 as well as a $0.6 million other intangible asset impairment loss recorded by our industrial reportable segment during fiscal 2009. Additionally, during the third quarter of fiscal 2017, we recorded an impairment loss on an indefinite-lived tradename for approximately $4.9 million, which was recorded by our consumer reportable segment.

As previously reported, we had monitored the performance of our Kirker nail enamel business throughout fiscal 2016.  During the third quarter ended February 29, 2016, we reported that performance shortfalls for Kirker were attributable to a delay in new business.  We performed our annual goodwill impairment analysis during the fourth quarter of fiscal 2016, which resulted in an excess of fair value over

RPM INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

carrying value of 8% for our Kirker reporting unit. During the quarter ended August 31, 2016, we reported that while Kirker’s first quarter results were below the comparable prior year period, their performance was in line with expectations, and our assessment of the Kirker business did not indicate the presence of any goodwill impairment triggering events.

For the quarter ended November 30, 2016, we identified certain factors that we considered important in assessing the requirement to perform an interim impairment evaluation for our Kirker reporting unit.  First, Kirker’s three month operating results for the period ended November 30, 2016 were significantly below historical and expected operating results and downward adjustments were recently made regarding our expectations for Kirker’s performance. In the quarter ended November 30, 2016, Kirker experienced market share losses at several key customers, including the loss of its largest customer, which accounted for over 15% of Kirker’s fiscal 2016 sales.  In addition, some problematic customer relationship issues surfaced during the quarter ended November 30, 2016, which resulted in a personnel change in a key leadership position at Kirker.  After considering the totality of these recent events, we determined that an interim step one goodwill impairment assessment was required, as well as an impairment assessment for our intangible and other long-lived assets.  Our testing resulted in the impairment charges outlined above for goodwill and other intangible assets.  

Our goodwill impairment assessment included estimating the fair value of our Kirker reporting unit and comparing it with its carrying amount at November 30, 2016.  Since the carrying amount of Kirker exceeded its fair value, additional steps were required to determine and recognize an impairment loss. Calculating the fair value of a reporting unit requires our significant use of estimates and assumptions, which are generally considered Level 3 inputs based on our review of the fair value hierarchy. We estimated the fair value of our Kirker reporting unit by applying a discounted future cash flow calculation to Kirker’s projected earnings before interest, taxes, depreciation and amortization (“EBITDA”). In applying this methodology, we relied on a number of factors, including actual and forecasted operating results and market data for the nail enamel industry.  Discounted cash flow calculations represent a common measure used to value and buy or sell businesses in our industry.  The discounted cash flow used in the goodwill impairment test for Kirker assumed discrete period revenue growth through fiscal 2021 that was reflective of recent downward revisions to previous expectations for future growth from market opportunities related to contracting with certain retailers to fill nail polish for their respective private label brands as well as downward revisions to growth expectations for the Kirker liquid nail polish business below the expected liquid nail polish growth rates for the markets in which Kirker operates.  In the terminal year we assumed a long-term earnings growth rate of 3.0% that we believe is appropriate given the current industry specific expectations.  As of the valuation date, we utilized a weighted-average cost of capital of 8.0%, which we believed was appropriate as it reflected the relative risk, the time value of money, and was consistent with Kirker’s peer group. After recording the goodwill impairment charge of $140.7 million, no goodwill remained on the Kirker balance sheets as of November 30, 2016.  

Our other intangible asset impairment assessment involved estimating the fair value of each of Kirker’s amortizable intangibles and other long-lived assets as well as the indefinite-lived tradename asset and comparing it with its carrying amount. Measuring a potential impairment of amortizable intangibles and other long-lived assets requires the use of various estimates and assumptions, including the determination of which cash flows are directly related to the assets being evaluated, the respective useful lives over which those cash flows will occur and potential residual values, if any.  As the results of our testing indicated that the carrying values of certain of these assets would not be recoverable, as outlined above, we recorded other intangible asset impairments of approximately $45.7 million for the three and six months ended November 30, 2016.    

Calculating the fair value of the Kirker indefinite-lived tradename required our significant use of estimates and assumptions. We estimated the fair value of Kirker’s indefinite-live tradename by applying a relief-from-royalty calculation, which included discounted future cash flows related to its projected revenues. In applying this methodology, we relied on a number of factors, including actual and forecasted revenues and market data for the nail enamel industry.  As the carrying amount of the tradename exceeded its fair value, the impairment loss of $2.0 million was recorded for the three and six months ended November 30, 2016.

Certain assets and liabilities are subject to nonrecurring fair value measurements, which typically are remeasured at fair value as a result of impairment charges.  As a result of the impairment testing described above, the fair value of Kirker’s identifiable intangible assets and indefinite-lived tradename were recalculated, and the resulting fair value approximated $5.8 million at November 30, 2016.  Based upon our review of the fair value hierarchy, the inputs used in these fair value measurements were considered Level 3 inputs.

Marketable securities, included in other current and long-term assets totaling $102.5 million and $71.3 million at November 30, 2017, respectively, and included in other current and long-term assets totaling $89.5 million and $75.0 million at May 31, 2017, respectively, are composed of available-for-sale securities and are reported at fair value.  We carry a portion of our marketable securities portfolio in long-term assets since they are generally held for the settlement of our general and product liability insurance claims processed through our wholly owned captive insurance subsidiaries.

Marketable securities are composed of available-for-sale securities and are reported at fair value. Realized gains and losses on sales of investments are recognized in net income on the specific identification basis. Changes in the fair values of securities that are considered temporary are recorded as unrealized gains and losses, net of applicable taxes, in accumulated other comprehensive (loss) within stockholders’ equity. Other-than-temporary declines in market value from original cost are reflected in operating income in the period in which the unrealized losses are deemed other than temporary. In order to determine whether other-than-temporary declines in market value have occurred, the duration of the decline in value and our ability to hold the investment are considered in conjunction with an evaluation of the strength of the underlying collateral and the extent to which the investment’s amortized cost or cost, as appropriate, exceeds its related market value.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Gross gains realized on sales of investments were $2.0 million and $1.9 million for the quarters ended November 30, 2017 and 2016, respectively.  During the second quarter of fiscal 2017, we recognized gross realized losses on sales of investments of $0.8 million, while such losses were de minimis during the current fiscal quarter. During the second quarter of fiscal 2017, we recognized losses of approximately $0.2 million for securities deemed to have other-than-temporary impairments, while there were no such losses during the current fiscal quarter.  

Gross gains realized on sales of investments were $6.1 million and $4.7 million for the six months ended November 30, 2017 and 2016, respectively.  During the first half of fiscal 2018 and 2017, we recognized gross realized losses on sales of investments of $1.2 million and $1.0 million, respectively. During the first half of fiscal 2017, we recognized losses of approximately $0.4 million for securities deemed to have other-than-temporary impairments, while there were no such losses during the first half of fiscal 2018.  These amounts are included in investment (income), net in the Consolidated Statements of Income.

Summarized below are the securities we held at November 30, 2017 and May 31, 2017 that were in an unrealized loss position and that were included in accumulated other comprehensive (loss), aggregated by the length of time the investments had been in that position:

	November 30, 2017					May 31, 2017
(In thousands)	Fair Value		Gross Unrealized Losses			Fair Value		Gross Unrealized Losses
Total investments with unrealized losses	$	55,199	$	(2,602	)	$	59,987	$	(3,505	)
Unrealized losses with a loss position for less than 12 months		13,813		(75	)		40,854		(2,983	)
Unrealized losses with a loss position for more than 12 months		41,386		(2,527	)		19,133		(522	)

We have reviewed all of the securities included in the table above and have concluded that we have the ability and intent to hold these investments until their cost can be recovered, based upon the severity and duration of the decline. Therefore, we did not recognize any other-than-temporary impairment losses on these investments. The unrealized losses generally relate to investments whose fair values at November 30, 2017 were less than 15% below their original cost. From time to time, we may experience significant volatility in general economic and market conditions.  If we were to experience unrealized losses that were to continue for longer periods of time, or arise to more significant levels of unrealized losses within our portfolio of investments in marketable securities in the future, we may recognize additional other-than-temporary impairment losses. Such potential losses could have a material impact on our results of operations in any given reporting period. As such, we continue to closely evaluate the status of our investments and our ability and intent to hold these investments.

The net carrying values of debt securities at November 30, 2017, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

NOTE 5 — FAIR VALUE MEASUREMENTS

Financial instruments recorded in the balance sheet include cash and cash equivalents, trade accounts receivable, marketable securities, notes and accounts payable, and debt.

An allowance for anticipated uncollectible trade receivable amounts is established using a combination of specifically identified accounts to be reserved, and a reserve covering trends in collectibility. These estimates are based on an analysis of trends in collectibility and past experience, but are primarily made up of individual account balances identified as doubtful based on specific facts and conditions. Receivable losses are charged against the allowance when we confirm uncollectibility.

The valuation techniques utilized for establishing the fair values of assets and liabilities are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect management’s market assumptions. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value, as follows:

Level 1 Inputs — Quoted prices for identical instruments in active markets.

Level 2 Inputs — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 Inputs — Instruments with primarily unobservable value drivers.

The following tables present our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy.

(In thousands)	QuotedPrices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)			Fair Value at November 30, 2017

Our marketable securities are primarily composed of available-for-sale securities, and are valued using a market approach. The availability of inputs observable in the market varies from instrument to instrument and depends on a variety of factors including the type of instrument, whether the instrument is actively traded, and other characteristics particular to the transaction. For most of our financial instruments, pricing inputs are readily observable in the market, the valuation methodology used is widely accepted by market participants, and the valuation does not require significant management discretion. For other financial instruments, pricing inputs are less observable in the market and may require management judgment.

The contingent consideration represents the estimated fair value of the additional variable cash consideration payable in connection with recent acquisitions that is contingent upon the achievement of certain performance milestones. We estimated the fair value using expected future cash flows over the period in which the obligation is expected to be settled, and applied a discount rate that appropriately captures a market participant's view of the risk associated with the obligation, which are considered to be Level 3 inputs. During the first half of fiscal 2018, we paid approximately $3.3 million for settlements of contingent consideration obligations relating to certain performance milestones that were established in prior periods and achieved during the current period.  During the first half of fiscal 2017, we paid approximately $4.1 million for settlements of contingent consideration obligations relating to certain performance milestones that were established in prior periods and achieved during last year’s first half. These amounts are reported in payments of acquisition-related contingent consideration in cash flows from financing activities in the Consolidated Statements of Cash Flows.

The carrying value of our current financial instruments, which include cash and cash equivalents, marketable securities, trade accounts receivable, accounts payable and short-term debt approximates fair value because of the short-term maturity of these financial instruments. At November 30, 2017 and May 31, 2017, the fair value of our long-term debt was estimated using active market quotes, based on our current incremental borrowing rates for similar types of borrowing arrangements, which are considered to be Level 2 inputs. Based on the analysis performed, the fair value and the carrying value of our financial instruments and long-term debt as of November 30, 2017 and May 31, 2017 are as follows:

NOTE 6 - DERIVATIVES AND HEDGING

Derivative Instruments and Hedging Activities

We are exposed to market risks, such as changes in foreign currency exchange rates and interest rates. To manage the volatility related to these exposures, from time to time, we enter into various derivative transactions. We use various types of derivative instruments including forward contracts and swaps. We formally assess, designate and document, as a hedge of an underlying exposure, each qualifying derivative instrument that will be accounted for as an accounting hedge at inception. Additionally, we assess, both at inception and at least quarterly thereafter, whether the financial instruments used in the hedging transaction are effective at offsetting changes in either the fair values or cash flows of the underlying exposures.

Net Investment Hedge

In October 2017, as a means of mitigating the impact of currency fluctuations on our Euro investments in foreign entities, we executed a fair value hedge and two cross currency swaps, in which we will pay variable rate interest in Euros and receive fixed rate interest in U.S. Dollars with a combined notional amount of approximately €85.25 million ($100 million U.S. Dollar equivalent), and which have a maturity date of November 2022. This effectively converts a portion of our U.S. Dollar denominated fixed rate debt to Euro denominated variable rate debt. The fair value hedge is recognized at fair value in our Consolidated Balance Sheets, while changes in the fair value of the hedge are recognized in interest expense in our Consolidated Statements of Income. We designated the swaps as net investment hedges of our net investment in our European operations under ASU 2017-12 and applied the spot method to these hedges. The changes in fair value of the derivative instruments that are designated and qualify as hedges of net investments in foreign operations are recognized in accumulated other comprehensive income (“AOCI”) to offset the changes in the values of the net investments being hedged.  Amounts released from AOCI and reclassified into interest expense did not have a material impact on our Consolidated Financial Statements for any period presented.

Derivatives Designated as Cash Flow Hedging Instruments

We have designated certain forward contracts as hedging instruments pursuant to ASC No. 815 (“ASC 815”), “Derivatives and Hedging.” Changes in the fair value of these highly effective hedges are recorded as a component of AOCI. During the period in which a forecasted transaction affects earnings, amounts previously recorded as a component of AOCI are reclassified into earnings as a component of cost of sales.  Amounts released from AOCI and reclassified into earnings did not have a material impact on our Consolidated Financial Statements for any period presented. As of November 30, 2017, and May 31, 2017 the notional amount of the forward contracts held to sell international currencies was $14.6 million and $9.8 million, respectively.

RPM INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Derivatives Not Designated as Hedges

At November 30, 2017, we held three foreign currency forward contracts designed to reduce our exposure to changes in the cash flows of intercompany foreign-currency-denominated loans related to changes in foreign currency exchange rates by fixing the functional currency cash flows.  These contracts have not been designated as hedges; therefore, the changes in fair value of these derivatives are recognized in earnings as a component of other (income) expense. Amounts recognized in earnings did not have a material impact on our Consolidated Financial Statements for any period presented. As of November 30, 2017 and May 31, 2017, the notional amounts of the forward contracts held to purchase foreign currencies was $151.7 million and $49.4 million, respectively.

Disclosure about Derivative Instruments

All of our derivative assets and liabilities measured at fair value are classified as Level 2 within the fair value hierarchy. We determine the fair value of our derivatives based on valuation methods, which project future cash flows and discount the future amounts to present value using market based observable inputs, including interest rate curves, foreign currency rates, as well as future and basis point spreads, as applicable.

The fair values of qualifying and non-qualifying instruments used in hedging transactions as of November 30, 2017 and May 31, 2017 are as follows:

NOTE 9 — INCOME TAXES

The effective income tax expense rate was 12.2% for the three months ended November 30, 2017 compared to an effective income tax benefit rate of 34.3% for the three months ended November 30, 2016.  The effective income tax expense rate was 19.6% for the six months ended November 30, 2017 compared to an effective income tax benefit rate of 3.7% for the six months ended November 30, 2016.

The effective tax rate for the three months ended November 30, 2017 and 2016 reflect variances from the 35% federal statutory rate due to lower effective tax rate of certain of our foreign subsidiaries, the benefit of the domestic manufacturing deduction, partially offset by the unfavorable impact of state and local taxes. Additionally, we recorded favorable discrete tax adjustments for excess tax benefits related to equity compensation of $2.0 million and $1.0 million, respectively, in the three-month periods ended November 30, 2017 and 2016; and $3.5 million and $11.3 million, respectively, for the six month periods ended November 30, 2017 and 2016.

Additionally, during the three-month period ended November 30, 2017, we approved and completed a foreign legal entity restructuring and corresponding planning strategy that resulted in a discrete tax benefit of $18.0 million. Of this amount, a U.S. tax benefit of $1.2 million resulted from the generation of foreign tax credits which offset a deemed inclusion in U.S. taxable income of foreign earnings.  The planned subsequent distribution of these foreign earnings resulted in a benefit of $16.8 million for a corresponding reduction in the estimated deferred income tax liability for the U.S. tax cost associated with unremitted foreign earnings that are not considered permanently reinvested.

Furthermore, income tax expense for the six-month period ended November 30, 2017 reflects the net discrete tax benefit of $9.0 million that we previously reported during the three-month period ended August 31, 2017.  As of November 30, 2017, the amount of unremitted foreign earnings, not previously subject to U.S. tax that may be repatriated and the corresponding deferred tax liability have been adjusted to $221.8 million and $63.4 million, respectively. The reduction to the amount of unremitted foreign earnings that may be repatriated, and the related tax impact, is principally the result of the above noted transaction related to the foreign earnings not considered permanently reinvested, partially offset by the impact of foreign currency translation. The increase to the deferred tax liability related to foreign currency translation was recorded as a component of accumulated other comprehensive income.

We have not provided for U.S. income and foreign withholding taxes on the remaining foreign subsidiaries’ undistributed earnings because such earnings have been retained and reinvested by the subsidiaries as of November 30, 2017.  Accordingly, no provision has been made for U.S. income taxes or foreign withholding taxes, which may become payable if the remaining undistributed earnings of foreign subsidiaries were paid to us as dividends.

On December 22, 2017, the Tax Cuts and Jobs Act (the “Act”) was enacted into law.  The income tax effects of changes in tax laws are recognized in the period when enacted. The Act provides for numerous significant tax law changes and modifications with varying effective dates, which include reducing the corporate income tax rate from 35% to 21%, creating a territorial tax system (with a one-time mandatory tax on previously deferred foreign earnings), broadening the tax base and allowing for immediate capital expensing of certain qualified property.

As a fiscal year-end taxpayer, certain provisions of the Act will begin to impact us in our fiscal third quarter ending February 28, 2018, while other provisions will impact us beginning in fiscal 2019. The corporate tax rate reduction is effective for RPM as of January 1, 2018 and, accordingly, will reduce our current fiscal year federal statutory rate to a blended rate of approximately 29.2%.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

We are currently analyzing the various components of the Act and its impact on our financial statements, including the estimated impact resulting from the re-measurement of our deferred tax assets and liabilities and the estimated charge for the one-time tax on our deferred foreign earnings and expect to record provisional amounts for these impacts in our third quarter financial statements.

We regularly assess our permanent reinvestment assertion regarding undistributed foreign earnings.  The Act includes other provisions that may factor into our reinvestment assertions.  Any prospective changes in our assertions regarding permanent reinvestment of undistributed earnings will be recorded in the period of the change.

NOTE 11 — STOCK REPURCHASE PROGRAM

On January 8, 2008, we announced our authorization of a stock repurchase program under which we may repurchase shares of RPM International Inc. common stock at management’s discretion for general corporate purposes. Our current intent is to limit our repurchases only to amounts required to offset dilution created by stock issued in connection with our equity-based compensation plans, or approximately one to two million shares per year. As a result of this authorization, we may repurchase shares from time to time in the open market or in private transactions at various times and in amounts and for prices that our management deems appropriate, subject to insider trading rules and other securities law restrictions. The timing of our purchases will depend upon prevailing market conditions, alternative uses of capital and other factors. We may limit or terminate the repurchase program at any time. During the three and six month periods ended November 30, 2017 and 2016, we did not repurchase any shares of our common stock under this program.

(2) Restricted shares totaling 123,262 and 99,612 for the three and six months ended November 30, 2017, respectively, were excluded from the calculation of diluted earnings per share because the grant price of the restricted shares exceeded the average market price of the shares during the period and their effect, accordingly, would have been anti-dilutive. There were 243,000 shares of restricted stock identified as being anti-dilutive for the three months ended November 30, 2016; and none identified as being anti-dilutive for the six months ended November 30, 2016. In addition, stock appreciation rights (“SARs”) totaling 600,000 for the three and six months ended November 30, 2017, and 1,170,000 for the three and six months ended November 30, 2016, were excluded from the calculation of diluted earnings per share as their effect would have been anti-dilutive.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

The decrease in pension and postretirement benefit cost from fiscal 2017 to 2018 reflects the impact of increased asset values, which we expect will generate higher returns, and a change in estimate for lump sum valuations. We expect that pension expense will fluctuate on a year-to-year basis, depending upon the investment performance of plan assets and potential changes in interest rates, but such changes are not expected to be material to our consolidated financial results. We previously disclosed in our financial statements for the fiscal year ended May 31, 2017 that we expected to contribute approximately $1.0 million to our retirement plans in the U.S. and approximately $7.0 million to plans outside the U.S. during the current fiscal year. As of November 30, 2017, this has not changed.

NOTE 14 – CONTINGENCIES AND OTHER ACCRUED LOSSES

We provide, through our wholly owned insurance subsidiaries, certain insurance coverage, primarily product liability coverage, to our other subsidiaries. Excess coverage is provided by third-party insurers. Our product liability accruals provide for these potential losses as well as other uninsured claims.  Product liability accruals are established based upon actuarial calculations of potential liability using industry experience, actual historical experience and actuarial assumptions developed for similar types of product liability claims, including development factors and lag times.  To the extent there is a reasonable possibility that potential losses could exceed the amounts already accrued, we believe that the amount of any such additional loss would be immaterial to our results of operations, liquidity and consolidated financial position.

We also offer warranties on many of our products, as well as long-term warranty programs at certain of our businesses, and have established product warranty liabilities. We review these liabilities for adequacy on a quarterly basis and adjust them as necessary. The primary factors that could affect these liabilities may include changes in performance rates as well as costs of replacement. Provision for estimated warranty costs is recorded at the time of sale and periodically adjusted, as required, to reflect actual experience. It is probable that we will incur future losses related to warranty claims we have received but that have not been fully investigated and related to claims not yet received. While our warranty liabilities represent our best estimates at November 30, 2017, we can provide no assurances that we will not experience material claims in the future or that we will not incur significant costs to resolve such claims beyond the amounts accrued or beyond what we may recover from our suppliers. Based upon the nature of the expense, product warranty expense is recorded as a reduction of sales, as a component of cost of sales, or within selling, general and administrative expense.

Also, due to the nature of our businesses, the amount of claims paid can fluctuate from one period to the next.  While our warranty liabilities represent our best estimates of our expected losses at any given time, from time-to-time we may revise our estimates based on our experience relating to factors such as weather conditions, specific circumstances surrounding product installations and other factors.

The following table includes the changes in our accrued warranty balances:

	Three Months Ended						Six Months Ended
	November 30,			November 30,			November 30,			November 30,
	2017			2016			2017			2016

Provision charged to expense		4,716			6,663			9,979			11,072
Ending Balance	$	14,457		$	15,954		$	14,457		$	15,954

(1) Primarily claims paid during the year.

In addition, like other companies participating in similar lines of business, some of our subsidiaries are involved in proceedings relating to environmental matters.  It is our policy to accrue remediation costs when it is probable that such efforts will be required and the related costs can be reasonably estimated.  These liabilities are undiscounted and are not material to our financial statements during any of the periods presented.

We were notified by the SEC on June 24, 2014, that we are the subject of a formal investigation pertaining to the timing of our disclosure and accrual of loss reserves in fiscal 2013 with respect to the previously disclosed U.S. Department Of Justice (the “DOJ”) and the U.S. General Services Administration (the “GSA”) Office of Inspector General investigation into compliance issues relating to

RPM INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Tremco Roofing Division’s GSA contracts. As previously disclosed, our audit committee completed an investigation into the facts and circumstances surrounding the timing of our disclosure and accrual of loss reserves with respect to the GSA and DOJ investigation, and determined that it was appropriate to restate our financial results for the first, second and third quarters of fiscal 2013.  These restatements had no impact on our audited financial statements for the fiscal years ended May 31, 2013 or 2014. The audit committee’s investigation concluded that there was no intentional misconduct on the part of any of our officers.

In connection with the foregoing, on September 9, 2016, the SEC filed an enforcement action against us and our General Counsel.  We have cooperated with the SEC’s investigation and believe the allegations in the complaint mischaracterize both our and our General Counsel’s actions in connection with the matters related to our quarterly results in fiscal 2013 and are without merit.  Both we and our General Counsel filed motions to dismiss the complaint on February 24, 2017.  Those motions to dismiss the complaint were denied by the Court on September 29, 2017.  We and our General Counsel filed answers to the complaint on October 16, 2017.  No trial date has been set, but formal discovery will commence in January 2018.  We intend to continue to contest the allegations in the complaint vigorously.

The action by the SEC could result in sanctions against us and/or our General Counsel and could impose substantial additional costs and distractions, regardless of its outcome. We have determined that it is probable that we will incur a loss relating to this matter and have estimated a range of potential loss. We have accrued at the low end of the range of loss, as no amount within the range is more likely to occur, and no amount within the estimated range of loss would have a material impact on our consolidated financial condition, results of operations or cash flows.

With respect to a case pending against one of our subsidiaries in which there is alleged both trade secret and trademark infringement, during the quarter ended August 31, 2017, the court denied our motion for summary judgment and based on our current understanding of the claim we have determined that it is reasonably possible that we may incur a loss related to this claim; however we cannot estimate the amount or range of any potential loss.

NOTE 16 — SEGMENT INFORMATION

We operate a portfolio of businesses and product lines that manufacture and sell a variety of specialty paints, protective coatings and roofing systems, sealants and adhesives. We manage our portfolio by organizing our businesses and product lines into three reportable segments: the industrial reportable segment, the consumer reportable segment and the specialty reportable segment. Within each reportable segment, we aggregate operating segments or product lines that consist of individual companies or groups of companies and product lines, which generally address common markets, share similar economic characteristics, utilize similar technologies and can share manufacturing or distribution capabilities. Our seven operating segments represent components of our business for which separate financial information is available that is utilized on a regular basis by our chief operating decision maker in determining how to allocate the assets of the company and evaluate performance. These seven operating segments are each managed by an operating segment manager, who is responsible for the day-to-day operating decisions and performance evaluation of the operating segment’s underlying businesses.

Our industrial reportable segment products are sold throughout North America and also account for the majority of our international sales. Our industrial product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. The industrial reportable segment comprises three separate operating segments — Tremco Group, tremco illbruck Group and Performance Coatings Group. Products and services within this reportable segment include construction chemicals, roofing systems, weatherproofing and other sealants, and polymer flooring.

Our consumer reportable segment manufactures and markets professional use and do-it-yourself (“DIY”) products for a variety of mainly consumer applications, including home improvement and personal leisure activities. Our consumer segment’s major manufacturing and distribution operations are located primarily in North America, along with a few locations in Europe and other parts of the world. Our consumer reportable segment products are primarily sold directly to mass merchandisers, home improvement centers, hardware stores, paint stores, craft shops, cosmetic companies and through distributors. This reportable segment comprises three operating segments — Rust-Oleum Group, DAP Group and SPG-Consumer Group. Products within this reportable segment include specialty, hobby and professional paints; nail enamels; caulks; adhesives; silicone sealants and wood stains.

Our specialty reportable segment products are sold throughout North America and a few international locations, primarily in Europe. Our specialty product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. The specialty reportable segment is a single operating segment, which offers products that include industrial cleaners, restoration services equipment, colorants, exterior finishes, edible coatings and specialty glazes for pharmaceutical and food industries, and other specialty OEM coatings.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

In addition to our three reportable segments, there is a category of certain business activities and expenses, referred to as corporate/other, that does not constitute an operating segment. This category includes our corporate headquarters and related administrative expenses, results of our captive insurance companies, gains or losses on the sales of certain assets and other expenses not directly associated with any reportable segment. Assets related to the corporate/other category consist primarily of investments, prepaid expenses and headquarters’ property and equipment. These corporate and other assets and expenses reconcile reportable segment data to total consolidated income before income taxes and identifiable assets.

We reflect income from our joint ventures on the equity method, and receive royalties from our licensees.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our financial statements include all of our majority-owned subsidiaries.  Investments in less-than-majority-owned joint ventures for which we have the ability to exercise significant influence over are accounted for under the equity method. Preparation of our financial statements requires the use of estimates and assumptions that affect the reported amounts of our assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We continually evaluate these estimates, including those related to our allowances for doubtful accounts; inventories; allowances for recoverable taxes; uncertain tax positions; useful lives of property, plant and equipment; goodwill and other intangible assets; environmental, warranties and other contingent liabilities; income tax valuation allowances; pension plans; and the fair value of financial instruments. We base our estimates on historical experience, our most recent facts, and other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of our assets and liabilities. Actual results, which are shaped by actual market conditions, may differ materially from our estimates.

A comprehensive discussion of the accounting policies and estimates that are the most critical to our financial statements are set forth in our Annual Report on Form 10-K for the year ended May 31, 2017.  There have been no significant changes in critical accounting policies or estimates since May 31, 2017.

BUSINESS SEGMENT INFORMATION

We operate a portfolio of businesses and product lines that manufacture and sell a variety of specialty paints, protective coatings and roofing systems, sealants and adhesives. We manage our portfolio by organizing our businesses and product lines into three reportable segments: the industrial reportable segment, the consumer reportable segment and the specialty reportable segment. Within each reportable segment, we aggregate operating segments or product lines that consist of individual companies or groups of companies and product lines, which generally address common markets, share similar economic characteristics, utilize similar technologies and can share manufacturing or distribution capabilities. Our seven operating segments represent components of our business for which separate financial information is available that is utilized on a regular basis by our chief operating decision maker in determining how to allocate the assets of the company and evaluate performance. These seven operating segments are each managed by an operating segment manager, who is responsible for the day-to-day operating decisions and performance evaluation of the operating segment’s underlying businesses. We evaluate the profit performance of our segments primarily based on income before income taxes, but also look to earnings (loss) before interest and taxes (“EBIT”) as a performance evaluation measure because interest expense is essentially related to acquisitions, as opposed to segment operations.

Our industrial reportable segment products are sold throughout North America and also account for the majority of our international sales. Our industrial product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. The industrial reportable segment comprises three separate operating segments — Tremco Group, tremco illbruck Group and Performance Coatings Group. Products and services within this reportable segment include construction chemicals, roofing systems, weatherproofing and other sealants, and polymer flooring.

Our specialty reportable segment products are sold throughout North America and a few international locations, primarily in Europe. Our specialty product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. The specialty reportable segment is a single operating segment, which offers products that include industrial cleaners, restoration services equipment, colorants, exterior finishes, edible coatings and specialty glazes for pharmaceutical and food industries, and other specialty OEM coatings.

In addition to our three reportable segments, there is a category of certain business activities and expenses, referred to as corporate/other, that does not constitute an operating segment. This category includes our corporate headquarters and related administrative expenses, results of our captive insurance companies, gains or losses on the sales of certain assets and other expenses not directly associated with any reportable segment. Assets related to the corporate/other category consist primarily of investments, prepaid expenses and headquarters’ property and equipment. These corporate and other assets and expenses reconcile reportable segment data to total consolidated income before income taxes, interest expense and earnings before interest and taxes.

(a) The presentation includes a reconciliation of Income (Loss) Before Income Taxes, a measure defined by generally accepted accounting principles ("GAAP") in the U.S., to EBIT.

(b) Interest (expense), net includes the combination of interest (expense) and investment income/(expense), net.

(c) EBIT is a non-GAAP measure, and is defined as earnings (loss) before interest and taxes.  We evaluate the profit performance of our segments based on income before income taxes, but also look to EBIT as a performance evaluation measure because interest expense is essentially related to acquisitions, as opposed to segment operations.  We believe EBIT is useful to investors for this purpose as well, using EBIT as a metric in their investment decisions.  EBIT should not be considered an alternative to, or more meaningful than, income before income taxes as determined in accordance with GAAP, since EBIT omits the impact of interest in determining operating performance, which represent items necessary to our continued operations, given our level of indebtedness.  Nonetheless, EBIT is a key measure expected by and useful to our fixed income investors, rating agencies and the banking community all of whom believe, and we concur, that this measure is critical to the capital markets' analysis of our segments' core operating performance.  We also evaluate EBIT because it is clear that movements in EBIT impact our ability to

25

attract financing.  Our underwriters and bankers consistently require inclusion of this measure in offering memoranda in conjunction with any debt underwriting or bank financing.  EBIT may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results.

RESULTS OF OPERATIONS

Three Months Ended November 30, 2017

Net Sales  Consolidated net sales of $1,315.4 million for the second quarter of fiscal 2018 grew by approximately 10.5% from net sales of $1,190.8 million for last year’s second quarter. Acquisitions added 4.7%, while organic sales, which include the impact of price and volume, improved by 4.2%.  Consolidated net sales for the quarter also reflect a favorable foreign exchange impact of 1.6%.

Industrial segment net sales for the current quarter grew by 11.0% to $702.9 million, from net sales of $633.4 million during the same period a year ago. The improvement was primarily due to organic growth of 5.4% during the quarter, driven mainly by North American roofing, but also by our polymer flooring businesses. Recent acquisitions contributed 3.3% to net sales during the current quarter, while favorable foreign exchange impacted net sales by 2.3% during the current quarter.

Consumer segment net sales for the quarter grew by 11.1% to $415.4 million, from $373.8 million during last year’s second quarter, due to growth in net sales from recent acquisitions of 7.3%.  This segment had growth in organic sales of 3.0% during the quarter versus the same period last year, driven primarily by sales of caulks and sealants, as well as improved results in select international markets.  Slightly favorable foreign currency impacted net sales in the consumer segment by 0.8% during the current quarter versus the same period a year ago.  

Specialty segment net sales for the quarter grew by 7.4% to $197.1 million, from $183.6 million during last year’s second quarter. Recent acquisitions provided 3.8% of the growth in net sales, while organic growth provided 2.8% during the current quarter, in spite of the loss of sales associated with the fiscal 2017 closure of an unprofitable European manufacturing facility. Organic growth in net sales was driven by recent hurricane activity that impacted our businesses serving the water damage restoration and equipment markets, as well as increases in specialty OEM industrial coatings and wood finishes.  Sales declined in our edible coatings business as expected due to the loss of a patent in August 2017, however, this business has been able to retain most of its larger customers.  Foreign currency had a slightly favorable impact on specialty segment net sales for the quarter by 0.8%.

Gross Profit Margin  Our consolidated gross profit margin of 41.9% of net sales for the second quarter of fiscal 2018 compares to a consolidated gross profit margin of 43.8% for the comparable period a year ago. This gross profit decline of approximately 1.9% of net sales includes the benefit of our current quarter organic growth in sales, which provided approximately 0.6% of net sales, or 60 basis points (“bps”), which was more than offset by the burden of overall higher raw material costs for approximately 110 bps, unfavorable manufacturing absorption for approximately 50 bps, and approximately 100 bps from an unfavorable mix of product sold versus last year.  We anticipate that rising raw material prices will continue to trend upward due to more robust global demand and rising petrochemical costs.

Selling, General and Administrative Expenses (“SG&A”)  Our consolidated SG&A expense during the current period was relatively flat versus the same period last year, but improved to 31.9% of net sales from 35.2% of net sales for the prior year quarter, resulting primarily from the 10.5% increase in net sales during the current quarter, combined with tighter cost controls during the current quarter and the benefit from severance actions taken during fiscal 2017 across each of our segments.  During fiscal 2017, we made a decision to exit our Flowcrete polymer flooring business located in the Middle East, and in connection with that decision, we performed an additional review of the collectability of accounts receivable which resulted in a loss of $11.4 million for increased bad debt reserves during last year’s second quarter. We continue to assess unprofitable facilities and businesses and could incur additional charges in the future.  Additional SG&A expense generated from companies acquired during the last 12 months approximated $13.1 million during the current quarter. Lastly, warranty expense for the quarter ended November 30, 2017 decreased slightly by approximately $1.9 million from the amount recorded during the comparable prior year period, and it is typical that warranty expense will fluctuate from period to period.  

Our industrial segment SG&A was approximately $5.0 million higher for the second quarter of fiscal 2018 versus the comparable prior year period, but decreased as a percentage of net sales, which reflects the industrial segment’s solid 11.0% growth in net sales combined with overall tighter cost controls during the current quarter and the benefit from severance actions taken during fiscal 2017. We will continue to focus on improving operating leverage throughout the industrial segment. As previously discussed, in connection with the decision to exit the Flowcrete Middle East business, during last year’s second quarter we incurred a loss of $11.4 million for increased bad debt reserves.  Additional SG&A expense generated from companies acquired during the last 12 months approximated $6.2 million for this segment during the current quarter.

26

Our consumer segment SG&A increased by approximately $7.4 million during the second quarter of fiscal 2018 versus the same period last year, but decreased as a percentage of net sales, reflecting overall tighter cost controls during the current quarter and the benefit from severance actions taken during fiscal 2017. Additionally, the consumer segment recorded lower employee compensation expense as well as slightly lower distribution expense during the current quarter. Recent acquisitions increased SG&A expense in this segment by approximately $5.9 million.    

Our specialty segment SG&A was approximately $1.2 million lower during the second quarter of fiscal 2018 versus the comparable prior year period, and decreased as a percentage of net sales, which reflects this segment’s 7.4% growth in net sales combined with overall tighter cost controls during the current quarter and the benefit from severance actions taken during fiscal 2017.  This segment also benefited from lower SG&A in connection with the fiscal 2017 closure of an unprofitable European manufacturing facility.  During the current quarter, recent acquisitions increased SG&A expense in this segment by approximately $1.0 million.  

SG&A expenses in our corporate/other category of $18.0 million during the second quarter of fiscal 2018 decreased by $11.0 million from $29.0 million recorded during last year’s second quarter, resulting primarily from lower healthcare and pension expense, as well as lower legal and acquisition-related professional fees.  

We recorded total net periodic pension and postretirement benefit costs of $10.8 million and $14.7 million for the second quarter of fiscal 2018 and 2017, respectively. The $3.9 million decrease in pension expense resulted from an approximate $2.0 million decline in net actuarial losses recognized during the current quarter versus last year’s second quarter, principally from a change in estimate for lump sum valuations, which were updated to incorporate future expectations of interest rates.  There was also a higher expected return on increased plan assets during the current quarter versus the same period last year for approximately $1.9 million. We expect that pension expense will fluctuate on a year-to-year basis, depending upon the investment performance of plan assets and potential changes in interest rates, but such changes are not expected to be material to our consolidated financial results.

Goodwill and Other Intangible Asset Impairments As described in Note 3, “Goodwill and Other Intangible Assets,” to the consolidated financial statements, we recorded impairment charges related to a reduction of the carrying value of goodwill and other intangible assets totaling $188.3 million during last year’s second quarter ended November 30, 2016.  For additional information, refer to Note 3 to the consolidated financial statements.

Interest Expense  Interest expense was $26.4 million for the second quarter of fiscal 2018 versus $22.9 million for the same period a year ago. Higher average borrowings, related to recent acquisitions, increased interest expense during this year’s second quarter by approximately $1.1 million versus the same period a year ago.  Excluding acquisition-related borrowings, lower average borrowings year-over-year decreased interest expense by approximately $0.1 million. Lastly, higher interest rates, which averaged 4.37% overall for the second quarter of fiscal 2018 compared with 4.21% for the same period of fiscal 2017, increased interest expense by approximately $2.5 million during the current quarter versus the same period last year.

Investment (Income), Net  Net investment income of approximately $3.7 million for the second quarter of fiscal 2018 compares to net investment income of $2.4 million during the same period last year.  Dividend and interest income totaled $1.7 million and $1.5 million for the second quarter of fiscal 2018 and 2017, respectively.  Net realized gains on the sales of investments totaled $2.0 million during the second quarter of fiscal 2018, while those gains were $1.1 million during the same period a year ago.  Impairments recognized on securities that management has determined are other-than-temporary declines in value approximated $0.2 million during the second quarter of fiscal 2017, while there were no such losses during the second quarter of the current fiscal year.  

Income (Loss) Before Income Taxes (“IBT”)  Our consolidated pretax income for the second quarter of fiscal 2018 of $109.2 million compares with pretax loss of $106.9 million for the same period a year ago.

Our industrial segment had IBT of $67.7 million, or 9.6% of net sales, for the quarter ended November 30, 2017, versus IBT of $50.3 million, or 7.9% of net sales, for the same period a year ago. Our industrial segment results reflect the impact of 5.4% growth in organic sales during the current quarter, offset primarily by the impact from higher raw material costs, distribution expense and unfavorable transactional foreign exchange expense.  Our consumer segment IBT approximated $45.1 million, or 10.9% of net sales, for the second quarter of fiscal 2018, versus the prior year second quarter pretax loss of $140.6 million.  During last year’s second quarter, we recorded goodwill and other intangible asset impairment charges of $188.3 million relating to this segment’s Kirker nail enamel business. The current quarter was challenging for our consumer segment, and we expect that to continue throughout the last half of the current fiscal year.  As a result, we currently anticipate an increase in our spending on advertising and promotions during the last half of the year.  Our specialty segment had pretax income of $34.4 million, or 17.5% of net sales for the quarter ended November 30, 2017, versus pretax income of $31.2 million, or 17.0% of net sales, for the same period a year ago, reflecting leverage on 2.8% growth in organic sales during the quarter, combined with the benefit from the closure of an unprofitable European manufacturing facility and severance actions taken during fiscal 2017.

27

Income Tax Rate The effective income tax expense rate was 12.2% for the three months ended November 30, 2017 compared to an effective income tax benefit rate of 34.3% for the three months ended November 30, 2016.  The decrease in the current quarter effective income tax rate as compared to the prior quarter rate is primarily due to a $18.0 million discrete tax benefit recorded in the current quarter. The discrete benefit resulted primarily from the execution of legal entity restructurings associated with tax planning strategies and a corresponding reduction to the deferred tax liability recorded for our estimate of the U.S. tax cost associated with unremitted foreign earnings that may be repatriated in the forseeable future.

Net Income (Loss)  Net income of $95.9 million for the quarter ended November 30, 2017 compares to net loss of $70.3 million for the comparable prior year period.  Net income attributable to noncontrolling interests approximated $0.4 million and $0.7 million for the second quarter of fiscal 2018 and 2017, respectively.  Net income attributable to RPM International Inc. stockholders for the second quarter of fiscal 2018 was $95.5 million, or 7.3% of consolidated net sales, which compared to net loss of $70.9 million, or 6.0% of consolidated net sales for the comparable prior year period.

Diluted income per share of common stock for the quarter ended November 30, 2017 of $0.70 compares with diluted loss per share of common stock of $0.54 for the quarter ended November 30, 2016.

Six Months Ended November 30, 2017

Net Sales  Consolidated net sales of $2,660.8 million for the first half of fiscal 2018 grew by approximately 8.9% from net sales of $2,442.8 million for last year’s first half. Acquisitions added 5.5%, while organic sales, which include the impact of price and volume, improved by 2.5%.  Consolidated net sales for this year’s first half also reflect a slightly favorable foreign exchange impact of 0.9%.

Industrial segment net sales for the current period grew by 9.4% to $1,432.7 million, from net sales of $1,309.3 million during the same period a year ago. The improvement was primarily due to recent acquisitions, which contributed 4.2% to net sales during the current period. Organic growth of 3.8% during this year’s first half resulted from improved performance by our roofing businesses, and several of our European businesses; especially certain U.K. based operations, but was slightly offset by a lagging performance by our businesses which continue to be impacted by recession and political unrest in Brazil, as well as our companies serving oil and gas markets.  Favorable foreign exchange impacted net sales by 1.4% during the current period.

Consumer segment net sales for this year’s first half grew by 8.9% to $842.6 million, primarily due to growth in net sales from recent acquisitions of 8.5%.  This segment had a virtually no growth in organic sales during the current period versus the same period last year, as the timing of shipments, inventory adjustments and softer consumer takeaway at our larger retail customers continued to impact this segment throughout the first half of fiscal 2018.  Slightly favorable foreign currency impacted net sales in the consumer segment by 0.4% during the current period versus the same period a year ago.  

Specialty segment net sales for this year’s first half grew by 7.1% to $385.6 million. Recent acquisitions provided 3.9% of the growth in net sales, while organic growth provided 2.9% during the current period, in spite of the loss of sales associated with the fiscal 2017 closure of an unprofitable European manufacturing facility. Organic growth in net sales was driven by recent hurricane activity that impacted our businesses serving the water damage restoration and equipment markets, as well as increases in specialty OEM industrial coatings.  Foreign currency had a slightly favorable impact on specialty segment net sales during this year’s first half by 0.3%.

Gross Profit Margin  Our consolidated gross profit margin of 42.2% of net sales for the first half of fiscal 2018 compares to a consolidated gross profit margin of 44.0% for the comparable period a year ago. This gross profit decline of approximately 1.8% of net sales primarily reflects current year margins that were burdened by the impact of overall higher raw material costs for approximately 90 bps, unfavorable manufacturing absorption for approximately 30 bps, and approximately 60 bps from an unfavorable mix of product sold versus last year.  We anticipate that rising raw material prices will continue to trend upward due to higher petrochemical costs and rising global demand.

SG&A  Our consolidated SG&A expense increased by approximately $10.4 million during the current period versus the same period last year, but improved to 30.6% of net sales for this year’s first half from 32.9% of net sales for the comparable prior year period, resulting primarily from the 8.9% increase in net sales during the current period, combined with tighter cost controls during the current period and the benefit from severance actions taken during fiscal 2017 across each of our segments.  During fiscal 2017, we made a decision to exit our Flowcrete polymer flooring business located in the Middle East, and in connection with that decision, we performed an additional review of the collectability of accounts receivable which resulted in a loss of $11.4 million for increased bad debt reserves during last year’s first half.  Additional SG&A expense generated from companies acquired during the last 12 months approximated $29.2 million during this year’s first half. There was also higher distribution and commission expense on higher sales volume during the current period versus last year, which was partially offset by lower professional services and bad debt expense.  Lastly, warranty expense for the six months ended November 30, 2017 decreased slightly by approximately $1.1 million from the amount recorded during the comparable prior year period, and it is typical that warranty expense will fluctuate from period to period.  

28

Our industrial segment SG&A was approximately $18.3 million higher for the first half of fiscal 2018 versus the comparable prior year period, but decreased as a percentage of net sales, which reflects the industrial segment’s solid 9.4% growth in net sales combined with overall tighter cost controls during the current period and the benefit from severance actions taken during fiscal 2017. We will continue to focus on improving operating leverage throughout the industrial segment. As previously discussed, in connection with the decision to exit the Flowcrete Middle East business, during last year’s first half we incurred a loss of $11.4 million for increased bad debt reserves. In addition to higher distribution and commission expense, recent acquisitions increased SG&A expense in this segment by approximately $14.7 million.

Our consumer segment SG&A increased by approximately $9.6 million during the first half of fiscal 2018 versus the same period last year, but decreased as a percentage of net sales, reflecting overall tighter cost controls during the current period and the benefit from severance actions taken during fiscal 2017. Recent acquisitions increased SG&A expense in this segment by approximately $12.8 million.    

Our specialty segment SG&A was approximately $1.8 million lower during the first half of fiscal 2018 versus the comparable prior year period, and decreased as a percentage of net sales, which reflects this segment’s 7.1% growth in net sales combined with overall tighter cost controls during the current period and the benefit from severance actions taken during fiscal 2017.  This segment also benefited from lower SG&A in connection with the fiscal 2017 closure of an unprofitable European manufacturing facility.  During the current period, recent acquisitions increased SG&A expense in this segment by approximately $1.7 million.  

SG&A expenses in our corporate/other category of $38.2 million during the first half of fiscal 2018 decreased by $15.0 million from $53.2 million recorded during last year’s first half, resulting primarily from lower healthcare and pension expense, as well as lower legal and acquisition-related professional fees.  

We recorded total net periodic pension and postretirement benefit costs of $21.6 million and $29.4 million for the first half of fiscal 2018 and 2017, respectively. The $7.8 million decrease in pension expense resulted from an approximate $4.0 million decline in net actuarial losses recognized during the current period versus last year’s first half, principally from a change in estimate for lump sum valuations, which were updated to incorporate future expectations of interest rates.  There was also a higher expected return on increased plan assets during the current period versus the same period last year for approximately $3.8 million. We expect that pension expense will fluctuate on a year-to-year basis, depending upon the investment performance of plan assets and potential changes in interest rates, but such changes are not expected to be material to our consolidated financial results.

Goodwill and Other Intangible Asset Impairments  As described in Note 3, “Goodwill and Other Intangible Assets,” to the consolidated financial statements, we recorded impairment charges related to a reduction of the carrying value of goodwill and other intangible assets totaling $188.3 million during last year’s second quarter and first half ended November 30, 2016.  For additional information, refer to Note 3 to the consolidated financial statements.

Interest Expense  Interest expense was $53.2 million for the first half of fiscal 2018 versus $45.7 million for the same period a year ago. Higher average borrowings, related to recent acquisitions, increased interest expense during this year’s first half by approximately $2.3 million versus the same period a year ago.  Excluding acquisition-related borrowings, higher average borrowings year-over-year increased interest expense by approximately $0.4 million. Lastly, higher interest rates, which averaged 4.34% overall for the first half of fiscal 2018 compared with 4.20% for the same period of fiscal 2017, increased interest expense by approximately $4.8 million during the current period versus the same period last year.

Investment (Income), Net  Net investment income of approximately $8.2 million for the first half of fiscal 2018 compares to net investment income of $6.3 million during the same period last year.  Dividend and interest income totaled $3.3 million and $3.0 million for the first half of fiscal 2018 and 2017, respectively.  Net realized gains on the sales of investments totaled $4.9 million during the first half of fiscal 2018, while those gains were $3.7 million during the same period a year ago.  Impairments recognized on securities that management has determined are other-than-temporary declines in value approximated $0.4 million during the first half of fiscal 2017, while there were no such losses for the first half of the current fiscal year.  

IBT  Our consolidated pretax income for the first half of fiscal 2018 of $264.5 million compares with pretax income of $41.6 million for the same period a year ago.

Our industrial segment had IBT of $156.6 million, or 10.9% of net sales, for the six months ended November 30, 2017, versus IBT of $139.6 million, or 10.7% of net sales, for the same period a year ago. Our industrial segment results reflect the impact of 9.4% growth in net sales during the current period, offset primarily by the impact from higher raw material costs, distribution expense and disappointing results in Latin America.  Our consumer segment IBT approximated $117.5 million, or 13.9% of net sales, for the first half of fiscal 2018, versus the prior year first half pretax loss of $70.5 million.  During last year’s first half, this segment recorded goodwill and other intangible asset impairment losses of $188.3 million.  Our specialty segment had pretax income of $67.6 million,

29

or 17.5% of net sales for the six months ended November 30, 2017, versus pretax income of $61.7 million, or 17.1% of net sales, for the same period a year ago, reflecting leverage on 7.1% growth in net sales during the current period, combined with the benefit from the closure of an unprofitable European manufacturing facility and severance actions taken during fiscal 2017. As previously reported, an edible coatings patent expired in the U.S. during the month of August 2017, and as a result, we anticipate the impact of the patent expiration on fiscal 2018 IBT to approximate at least $10.0 million.

Income Tax Rate The effective income tax expense rate was 19.6% for the six months ended November 30, 2017 compared to an effective income tax benefit rate of 3.7% for the six months ended November 30, 2016.

For the six-month period ended November 30, 2017, the favorable variance from the 35% statutory rate is primarily due to a cumulative net $27.0 million discrete benefit recorded in the six-month period primarily related to the execution of certain tax planning strategies and a corresponding reduction to the deferred tax liability recorded for our estimate of the U.S. tax cost associated with unremitted foreign earnings that may be repatriated in the foreseeable future.  

For the six-month period ended November 30, 2016, the variance from the 35% statutory rate is primarily due to an $11.3 million discrete tax benefit recorded for excess tax benefits related to equity compensation and the inflated effect of that rate benefit due to the relatively low level of pre-tax income.

Net Income  Net income of $212.8 million for the six months ended November 30, 2017 compares to net income of $43.1 million for the comparable prior year period.  Net income attributable to noncontrolling interests approximated $0.9 million and $1.3 million for the first half of fiscal 2018 and 2017, respectively.  Net income attributable to RPM International Inc. stockholders for the first half of fiscal 2018 was $211.9 million, or 8.0% of consolidated net sales, which compared to net income of $41.8 million, or 1.7% of consolidated net sales for the comparable prior year period.

Diluted income per share of common stock for the six months ended November 30, 2017 of $1.56 compares with diluted earnings per share of common stock of $0.32 for the six months ended November 30, 2016.

LIQUIDITY AND CAPITAL RESOURCES

Operating Activities

Approximately $115.2 million of cash was provided by operating activities during the first half of fiscal 2018, compared with $158.7 million of cash provided operating activities during the same period last year.

The net change in cash from operations includes the change in net income, which increased by $169.6 million during the first half of fiscal 2018 versus the same period during fiscal 2017.  Changes in working capital accounts and all other accruals used approximately $52.0 million more cash flow during the first half of fiscal 2018 versus the same period last year.

The change in accounts receivable during the first half of fiscal 2018 provided approximately $76.7 million less cash than during the same period a year ago.  Days sales outstanding at November 30, 2017 increased to 63.0 days from 59.5 days sales outstanding at November 30, 2016.  

During the first half of fiscal 2018, we spent approximately $18.7 million less cash for inventory purchases compared to our spending during the same period a year ago.  This resulted from the combination of timing of purchases by retail customers and a systematic reduction of inventory levels at certain businesses in our consumer segment. Days of inventory outstanding at November 30, 2017 decreased to 101.7 days from 102.5 days of inventory outstanding at November 30, 2016.

The change in accounts payable during the first half of fiscal 2018 used approximately $25.8 million more cash than during the first half of fiscal 2017, resulting principally from the timing of certain payments.  Accrued compensation and benefits used approximately $10.2 million less cash during the first half of fiscal 2018 versus fiscal 2017, due to lower bonus accruals made during fiscal 2018 versus fiscal 2017.  Other accruals and prepaids, including those for other short-term and long-term items and changes in accrued loss reserves, provided $22.5 million more cash during the first half of fiscal 2018 versus the same period a year ago, primarily from the timing of customer rebates.

Cash provided from operations, along with the use of available credit lines, as required, remain our primary sources of liquidity.

Investing Activities

Capital expenditures, other than for ordinary repairs and replacements, are made to accommodate our continued growth to achieve production and distribution efficiencies, expand capacity, introduce new technology, improve environmental health and safety capabilities, improve information systems, and enhance our administration capabilities. During the first half of fiscal 2018, we paid $54.6 million for acquisitions, net of cash acquired, versus $65.2 million during the comparable prior year period. Capital expenditures of $45.3 million during the first half of fiscal 2018 compare with depreciation of $40.4 million. In the comparable prior year period, capital expenditures were $48.0 million, which compared with depreciation of $35.6 million. We will be increasing our capital spending in fiscal 2018 in an effort to more aggressively invest in our internal growth initiatives, especially in overseas markets.  We anticipate that additional shifts at our production facilities, coupled with the capacity added through acquisition activity and our planned increase in future capital spending levels, will enable us to meet increased demand throughout fiscal 2018 and beyond.

Our captive insurance companies invest their excess cash in marketable securities in the ordinary course of conducting their operations, and this activity will continue. Differences in the amounts related to these activities on a year-over-year basis are primarily attributable to differences in the timing and performance of their investments balanced against amounts required to satisfy claims. At November 30, 2017, the fair value of our investments in marketable securities totaled $173.8 million, of which investments with a fair value of $55.2 million were in an unrealized loss position.  At May 31, 2017, the fair value of our investments in marketable securities totaled $164.5 million, of which investments with a fair value of $60.0 million were in an unrealized loss position.  The fair value of our portfolio of marketable securities is based on quoted market prices for identical, or similar, instruments in active or non-active markets or model-derived-valuations with observable inputs. We have no marketable securities whose fair value is subject to unobservable inputs. Total pretax unrealized losses recorded in accumulated other comprehensive income at November 30, 2017 and May 31, 2017 were $2.6 million and $3.5 million, respectively.

We regularly review our marketable securities in unrealized loss positions in order to determine whether or not we have the ability and intent to hold these investments. That determination is based upon the severity and duration of the decline, in addition to our evaluation of the cash flow requirements of our businesses. Unrealized losses at November 30, 2017 were generally related to the normal volatility in valuations over the past several months for a portion of our portfolio of investments in marketable securities. The unrealized losses generally relate to investments whose fair values at November 30, 2017 were less than 15% below their original cost or that have been in a loss position for less than six consecutive months. From time to time, we may experience significant volatility in general economic and market conditions.  If we were to experience unrealized losses that were to continue for longer periods of time, or arise to more significant levels of unrealized losses within our portfolio of investments in marketable securities in the future, we may recognize additional other-than-temporary impairment losses. Such potential losses could have a material impact on our results of operations in any given reporting period. As such, we continue to closely evaluate the status of our investments and our ability and intent to hold these investments.

As of November 30, 2017, approximately $225.4 million of our consolidated cash and cash equivalents were held at various foreign subsidiaries.  Undistributed earnings held at our foreign subsidiaries that are considered permanently reinvested will be used, for instance, to expand operations organically or for acquisitions in foreign jurisdictions.  Further, our operations in the U.S. generate sufficient cash flow to satisfy U.S. operating requirements.  Refer to Note 9, “Income Taxes,” to the Consolidated Financial Statements for additional information regarding unremitted foreign earnings.

Financing Activities

Our available liquidity, including our cash and cash equivalents and amounts available under our committed credit facilities, stood at $971.7 million at November 30, 2017. Our debt-to-capital ratio was 57.1% at November 30, 2017, compared with 59.3% at May 31, 2017.

4.250% Notes due 2048

On December 20, 2017, we closed an offering for $300.0 million aggregate principal amount of 4.250% Notes due 2048 (the “2048 Notes”).  The proceeds from the 2048 Notes will be used to repay $250.0 million in principal amount of unsecured senior notes due February 15, 2018, which bear interest at 6.50%, and for general corporate purposes.  Interest on the 2048 Notes accrues from December 20, 2017 and is payable semiannually in arrears on January 15^th and July 15^th of each year, beginning July 15, 2018, at a rate of 4.250% per year. The 2048 Notes mature on January 15, 2048.  The indenture governing this indebtedness includes cross-acceleration provisions. Under certain circumstances, where an event of default under our other instruments results in acceleration of the indebtedness under such instruments, holders of the indebtedness under the indenture are entitled to declare amounts outstanding immediately due and payable.

5.250% Notes due 2045 and 3.750% Notes due 2027

On March 2, 2017, we issued $50.0 million aggregate principal amount of 5.250% Notes due 2045 (the “2045 Notes”) and $400.0 million aggregate principal amount of 3.750% Notes due 2027 (the “2027 Notes”).  The 2045 Notes are a further issuance of the $250 million aggregate principal amount of 5.250% Notes due 2045 initially issued by us on May 29, 2015.  Interest on the 2045 Notes accrues from December 1, 2016 and is payable semiannually in arrears on June 1st and December 1st of each year, beginning June 1, 2017, at a rate of 5.250% per year. The 2045 Notes mature on June 1, 2045.  Interest on the 2027 Notes accrues from March 2, 2017 and is payable semiannually in arrears on March 15th and September 15th of each year, beginning September 15, 2017, at a rate of 3.750% per year. The 2027 Notes mature on March 15, 2027.  The indenture governing this indebtedness includes cross-acceleration provisions. Under certain circumstances, where an event of default under our other instruments results in acceleration of the indebtedness under such instruments, holders of the indebtedness under the indenture are entitled to declare amounts outstanding immediately due and payable.

Revolving Credit Agreement

During fiscal 2015, we entered into an $800.0 million unsecured syndicated revolving credit facility (the “Revolving Credit Facility”), which expires on December 5, 2019.  The Revolving Credit Facility includes sublimits for the issuance of swingline loans, which are comparatively short-term loans used for working capital purposes and letters of credit.  The aggregate maximum principal amount of the commitments under the Revolving Credit Facility may be expanded upon our request, subject to certain conditions, up to $1.0 billion.  The Revolving Credit Facility is available to refinance existing indebtedness, to finance working capital and capital expenditures, to satisfy all or a portion of our obligations relating to the plan of reorganization for our SPHC subsidiary, and for general corporate purposes.

The Revolving Credit Facility requires us to comply with various customary affirmative and negative covenants, including a leverage covenant and interest coverage ratio, which are calculated in accordance with the terms as defined by the credit agreement.  Under the terms of the leverage covenant, we may not permit our consolidated indebtedness as of any fiscal quarter end to exceed 65% of the sum of such indebtedness and our consolidated shareholders’ equity on such date.  The minimum required consolidated interest coverage ratio for EBITDA to interest expense is 3.50 to 1.  The interest coverage ratio is calculated at the end of each fiscal quarter for the four fiscal quarters then ended using an EBITDA as defined in the credit agreement.

As of November 30, 2017, we were in compliance with all financial covenants contained in our Revolving Credit Facility, including the leverage and interest coverage ratio covenants. At that date, our leverage ratio was 56.2%, while our interest coverage ratio was 8.4 to 1. Our available liquidity under our Revolving Credit Facility stood at $553.9 million at November 30, 2017.

Our access to funds under our Revolving Credit Facility is dependent on the ability of the financial institutions that are parties to the Revolving Credit Facility to meet their funding commitments. Those financial institutions may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period of time. Moreover, the obligations of the financial institutions under our Revolving Credit Facility are several and not joint and, as a result, a funding default by one or more institutions does not need to be made up by the others.  

As previously reported, during fiscal 2015, a plan of reorganization was confirmed (the “Bankruptcy Plan”) and, effective as of December 23, 2014, Bondex, SPHC, Republic and NMBFiL emerged from bankruptcy.  Accordingly, trusts were established under Section 524(g) of the United States Bankruptcy Code (together, the “Trust”) and were funded with first installments.  Borrowings under our Revolving Credit Facility were used to fund the initial trust payment of $450 million, which is classified as long-term debt in our Consolidated Balance Sheets.  The Trust was funded with $450 million in cash and a promissory note, bearing no interest and maturing on or before December 23, 2018 (the “Bankruptcy Note”). There is one remaining trust payment due. The Bankruptcy Plan, and Bankruptcy Note, provide that on or before December 23, 2018, a final payment of $125 million in cash, RPM stock or a combination thereof will be deposited into the Trust. The net present value of the Bankruptcy Note, or $121.8 million, is classified as other long-term liabilities in our consolidated financial statements at November 30, 2017.  A portion of the payments due under the Bankruptcy Note is secured by a right to the equity of SPHC, Republic and Bondex.  

All past and future contributions to the Trust are deductible for U.S. income tax purposes.  

Accounts Receivable Securitization Program

On May 9, 2017, we entered into a new, three-year, $200.0 million accounts receivable securitization facility (the “AR Program”). The maximum availability under the AR Program is $200.0 million. Availability is further subject to changes in the credit ratings of our customers, customer concentration levels or certain characteristics of the accounts receivable being transferred and, therefore, at certain times, we may not be able to fully access the $200.0 million of funding available under the AR Program.

32

As of November 30, 2017, there was no outstanding balance under the AR Program, which compares with the maximum availability on that date of $200.0 million.  The interest rate under the Purchase Agreement is based on the Alternate Base Rate, LIBOR Market Index Rate, one-month LIBOR or LIBOR for a specified tranche period, as selected by us, plus in each case, a margin of 0.70%. In addition, we are obligated to pay a monthly unused commitment fee based on the daily amount of unused commitments under the Agreement, which fee ranges from 0.30% to 0.50% based on usage.  The AR Program contains various customary affirmative and negative covenants and also contains customary default and termination provisions.

Our failure to comply with the covenants described above and other covenants contained in the Revolving Credit Facility could result in an event of default under that agreement, entitling the lenders to, among other things, declare the entire amount outstanding under the Revolving Credit Facility to be due and payable. The instruments governing our other outstanding indebtedness generally include cross-default provisions that provide that under certain circumstances, an event of default that results in acceleration of our indebtedness under the Revolving Credit Facility will entitle the holders of such other indebtedness to declare amounts outstanding immediately due and payable.

2.25% Convertible Senior Notes due 2020

On December 9, 2013, we issued $205 million of 2.25% convertible senior notes due 2020 (the “Convertible Notes”).  We pay interest on the Convertible Notes semi-annually on June 15^th and December 15^th of each year.  

The Convertible Notes will be convertible under certain circumstances and during certain periods at an initial conversion rate of 18.8905 shares of RPM common stock per $1,000 principal amount of notes (representing an initial conversion price of approximately $52.94 per share of common stock), subject to adjustment in certain circumstances.  In October 2017, we declared a dividend in excess of $0.24 per share, and consequently, the adjusted conversion rate at November 30, 2017 was 19.099650.  The initial conversion price represents a conversion premium of approximately 37% over the last reported sale price of RPM common stock of $38.64 on December 3, 2013.  Prior to June 15, 2020, the Convertible Notes may be converted only upon specified events, and, thereafter, at any time.  Upon conversion, the Convertible Notes may be settled, at RPM’s election, in cash, shares of RPM’s common stock, or a combination of cash and shares of RPM’s common stock.  The indenture governing this indebtedness includes cross-acceleration provisions. Under certain circumstances, where an event of default under our other instruments results in acceleration of the indebtedness under such instruments, holders of the indebtedness under the indenture are entitled to declare amounts outstanding immediately due and payable.

We account for the liability and equity components of the Convertible Notes separately, and in a manner that will reflect our nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. The effective interest rate on the liability component is 3.92%.  Contractual interest was $1.2 million and amortization of the debt discount was $0.7 million for the second quarter of fiscal 2018 and 2017. Contractual interest was $2.3 million for the first half of fiscal 2018 and 2017, while amortization of the debt discount was $1.5 million and $1.4 million for the first half of fiscal 2018 and 2017, respectively.  At November 30, 2017, the remaining period over which the debt discount will be amortized was 3.0 years, the unamortized debt discount was $9.7 million, and the carrying amount of the equity component was $20.7 million.

The following table summarizes our financial obligations and their expected maturities at November 30, 2017 and the effect such obligations are expected to have on our liquidity and cash flow in the periods indicated.

(1) Excluded from other long-term liabilities are our gross long-term liabilities for unrecognized tax benefits, which totaled $18.1 million at November 30, 2017. Currently, we cannot predict with reasonable reliability the timing of cash settlements to the respective taxing authorities related to these liabilities.

(2) These amounts represent our estimated cash contributions to be made in the periods indicated for our pension and postretirement plans, assuming no actuarial gains or losses, assumption changes or plan changes occur in any period.  The projection results assume the required minimum contribution will be contributed.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet financings, other than the minimum operating lease commitments included in the above Contractual Obligations table. We have no subsidiaries that are not included in our financial statements, nor do we have any interests in, or relationships with, any special purpose entities that are not reflected in our financial statements.

OTHER MATTERS

Environmental Matters

Environmental obligations continue to be appropriately addressed and, based upon the latest available information, it is not anticipated that the outcome of such matters will materially affect our results of operations or financial condition. Our critical accounting policies and estimates set forth above describe our method of establishing and adjusting environmental-related accruals and should be read in conjunction with this disclosure. For additional information, refer to “Part II, Item 1. Legal Proceedings.”

FORWARD-LOOKING STATEMENTS

The foregoing discussion includes forward-looking statements relating to our business. These forward-looking statements, or other statements made by us, are made based on our expectations and beliefs concerning future events impacting us and are subject to uncertainties and factors (including those specified below), which are difficult to predict and, in many instances, are beyond our control. As a result, our actual results could differ materially from those expressed in or implied by any such forward-looking statements. These uncertainties and factors include (a) global markets and general economic conditions, including uncertainties surrounding the volatility in financial markets, the availability of capital and the effect of changes in interest rates, and the viability of banks and other financial institutions; (b) the prices, supply and capacity of raw materials, including assorted pigments, resins, solvents, and other natural gas- and oil-based materials; packaging, including plastic containers; and transportation services, including fuel surcharges; (c) continued growth in demand for our products; (d) legal, environmental and litigation risks inherent in our construction and chemicals businesses and risks related to the adequacy of our insurance coverage for such matters; (e) the effect of changes in interest rates; (f) the effect of fluctuations in currency exchange rates upon our foreign operations; (g) the effect of non-currency risks of investing in and conducting operations in foreign countries, including those relating to domestic and international political, social, economic and regulatory factors; (h) risks and uncertainties associated with our ongoing acquisition and divestiture activities; (i) risks related to the adequacy of our contingent liability reserves; and (j) other risks detailed in our filings with the Securities and Exchange Commission, including the risk factors set forth in our Annual Report on Form 10-K for the year ended May 31, 2017, as the same may be updated from time to time. We do not undertake any obligation to publicly update or revise any forward-looking statements to reflect future events, information or circumstances that arise after the filing date of this document.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk from changes in raw materials costs, interest rates and foreign exchange rates since we fund our operations through long- and short-term borrowings and conduct our business in a variety of foreign currencies. There were no material potential changes in our exposure to these market risks since May 31, 2017.

ITEM 4. CONTROLS AND PROCEDURES

(a) EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES.

Our Chief Executive Officer and Chief Financial Officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of November 30, 2017 (the “Evaluation Date”), have concluded that as of the Evaluation Date, our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in the reports we file or submit under the Exchange Act (1) is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms, and (2) is accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosure.

(b) CHANGES IN INTERNAL CONTROL.

There were no changes in our internal control over financial reporting that occurred during the fiscal quarter ended November 30, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

SEC Investigation and Enforcement Action

As previously disclosed, we were notified by the SEC on June 24, 2014, that we are the subject of a formal investigation pertaining to the timing of our disclosure and accrual of loss reserves in fiscal 2013 with respect to the previously disclosed DOJ and GSA Office of Inspector General investigation into compliance issues relating to Tremco Roofing Division’s GSA contracts.  As previously disclosed, our audit committee completed an investigation into the facts and circumstances surrounding the timing of our disclosure and accrual of loss reserves with respect to the GSA and DOJ investigations, and determined that it was appropriate to restate our financial results for the first, second and third quarters of fiscal 2013.  These restatements had no impact on our audited financial statements for the fiscal years ended May 31, 2013 or 2014.  The audit committee’s investigation concluded that there was no intentional misconduct on the part of any of our officers.

In connection with the foregoing, on September 9, 2016, the SEC filed an enforcement action in the U.S. District Court for the District of Columbia against us and our General Counsel.  We have cooperated with the SEC’s investigation and believe the allegations in the complaint mischaracterize both our and our General Counsel’s actions in connection with the matters related to our quarterly results in fiscal 2013 and are without merit.  The complaint seeks disgorgement of gains that may have resulted from the conduct alleged in the complaint, and payment of unspecified monetary penalties from us and our General Counsel pursuant to Section 20(d) of the Securities Act and Section 21(d)(3) of the Exchange Act.  Further, the complaint seeks to permanently enjoin us from violations of Sections 17(a)(2) and (a)(3) of the Securities Act, Sections 13(a), 13(b)(2)(A) and 13(b)(2)(B) of the Exchange Act, and Exchange Act Rules 12b-20, 13a-1, 13a-11 and 13a-13, and to permanently enjoin our General Counsel from violations of Sections 17(a)(2) and (a)(3) of the Securities Act and Exchange Act Rules 13b2-1 and 13b2-2(a).  Both we and our General Counsel filed motions to dismiss the complaint on February 24, 2017.  Those motions to dismiss the complaint were denied by the Court on September 29, 2017.  We and our General Counsel filed answers to the complaint on October 16, 2017.  No trial date has been set, but formal discovery will commence in January 2018.  We intend to continue to contest the allegations in the complaint vigorously.

Environmental Proceedings

As previously disclosed, following an audit of Rust-Oleum Corporation’s Annual Quantity and Emissions Reports, the State of California’s South Coast Air Quality Management District (the “AQMD”) issued a Notice of Violation to Rust-Oleum alleging violations of AQMD’s Rule 314 (relating to fees for architectural coatings) and Rule 1113 (relating to limits on volatile organic compound content in architectural coatings).  Rust-Oleum estimates that it may be subject to excess emission fees, civil penalties and AQMD’s costs in the range of approximately $325,000 to $500,000 in the aggregate, and anticipates that all or a portion of such payments may be offset by a credit for excess amounts that Rust-Oleum has previously paid to AQMD.

As previously reported, several of our subsidiaries are, from time to time, identified as a “potentially responsible party” under the federal Comprehensive Environmental Response, Compensation and Liability Act and similar local environmental statutes. In some cases, our subsidiaries are participating in the cost of certain clean-up efforts or other remedial actions. Our share of such costs to date, however, has not been material and management believes that these environmental proceedings will not have a material adverse effect on our consolidated financial condition or results of operations. See “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Other Matters,” in Part I of this Quarterly Report on Form 10-Q.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the risk factors disclosed in Item 1A of our Annual Report on Form 10-K for the fiscal year ended May 31, 2017.

Consolidation, Noncontrolling Interests and Basis of Presentation

NOTE 1 — CONSOLIDATION, NONCONTROLLING INTERESTS AND BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles in the U.S. (“GAAP”) for interim financial information and the instructions to Form 10-Q. In our opinion, all adjustments (consisting of normal, recurring accruals) considered necessary for a fair presentation have been included for the three and six month periods ended November 30, 2017 and 2016.  For further information, refer to the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended May 31, 2017.

Our financial statements include all of our majority-owned subsidiaries. We account for our investments in less-than-majority-owned joint ventures, for which we have the ability to exercise significant influence, under the equity method.  Effects of transactions between related companies are eliminated in consolidation.

Noncontrolling interests are presented in our consolidated financial statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially-owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in our consolidated financial statements. Additionally, our consolidated financial statements include 100% of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control.

Our business is dependent on external weather factors. Historically, we have experienced strong sales and net income in our first, second and fourth fiscal quarters comprising the three month periods ending August 31, November 30 and May 31, respectively, with weaker performance in our third fiscal quarter (December through February).

Accounting Changes And Error Corrections [Abstract]

New Accounting Pronouncements

NOTE 2 — NEW ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” which establishes a comprehensive revenue recognition standard that will supersede nearly all existing revenue recognition guidance under GAAP. The new standard prescribes a five-step model for recognizing revenue, which will require significant judgment in its application. The new standard requires disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

Under the original issuance, the new standard would have applied to annual periods beginning after December 15, 2016, including interim periods therein. However, in August 2015, the FASB issued ASU 2015-14, which extends the standard effective date by one year and includes an option to apply the standard on the original effective date. The provisions of this ASU may be applied retrospectively to each prior reporting period presented, or on a modified retrospective basis by recognizing a cumulative catch-up transition amount at the date of initial application. We have selected the modified retrospective transition method, which we will apply upon adoption of the standard as of June 1, 2018.

Given the scope of work required to implement the recognition and disclosure requirements under the new standard, we began our assessment process during fiscal 2016.  Our progress to date includes a preliminary identification of areas which will require changes to policies, processes, systems or internal controls.  We expect revenue recognition for our broad portfolio of products and services to remain largely unchanged. However, the guidance is expected to change the timing of revenue recognition in certain areas, including our accounting for long-term construction contracts. While these impacts are not expected to be material to our overall Consolidated Financial Statements, we do anticipate that the new disclosure requirements surrounding revenue recognition will be significant. We continue to assess all potential impacts of the guidance and given the stage of our adoption procedures as well as our normal ongoing business dynamics, our preliminary conclusions and assessments of the potential impacts on each of our different business units’ revenue streams are subject to change.  

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which increases lease transparency and comparability among organizations.  Under the new standard, lessees will be required to recognize all assets and liabilities arising from leases on the balance sheet, with the exception of leases with a term of 12 months or less, which permits a lessee to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities.  ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and early adoption is permitted. The new standard requires the recognition and measurement of leases at the beginning of the earliest period presented using a modified retrospective approach, which includes a number of optional practical expedients that entities may elect to apply.  We are currently evaluating the impact this guidance will have on our Consolidated Financial Statements. At a minimum, total assets and total liabilities will increase in the period the ASU is adopted.  At November 30, 2017, our total undiscounted future minimum payments outstanding for operating lease obligations approximated $214.0 million.  

In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which makes a number of changes meant to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows.  The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted.  Upon adoption, entities must apply the guidance retrospectively to all periods presented.  We are currently evaluating the impact this guidance will have on our Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations: Clarifying the Definition of a Business,” with the objective of adding guidance to assist entities in evaluating whether transactions should be accounted for as acquisitions (disposals) of assets or of businesses. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. We are currently reviewing the impact this revised guidance will have on our Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” to eliminate step two from the goodwill impairment test in order to simplify the subsequent measurement of goodwill. The guidance is effective for fiscal years beginning after December 15, 2019. Early application is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Adoption of this guidance is not expected to have a material impact on our Consolidated Financial Statements.  

In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented.  The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years.  We are currently reviewing the impact this guidance will have on our Consolidated Financial Statements.  

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities,” which simplifies hedge accounting through changes to both designation and measurement requirements.  For hedges that qualify as highly effective, the new standard eliminates the requirement to separately measure and record hedge ineffectiveness, resulting in better alignment between the presentation of the effects of the hedging instrument and the hedged item in the financial statements.  ASU No. 2017-12 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  Early adoption is permitted in any interim period after issuance of the update.  Our early adoption of this pronouncement during our current quarter ended November 30, 2017 did not have a material impact on our Consolidated Financial Statements.  Refer to Note 6, “Derivatives and Hedging,” for further information.

Goodwill and Other Intangible Assets

Goodwill And Intangible Assets Disclosure [Abstract]

Goodwill and Other Intangible Assets

NOTE 3 – GOODWILL AND OTHER INTANGIBLE ASSETS

During the three month period ended November 30, 2016, we recorded impairment charges related to a reduction of the carrying value of goodwill and other intangible assets totaling $188.3 million.  All of the charges were recorded by our consumer reportable segment.  The goodwill impairment loss incurred during fiscal 2017 totaled $140.7 million, and the impairment losses for other intangible assets, totaling $47.8 million, related to formulae for $15.4 million; customer-related intangibles for $30.2 million; other intangibles for $0.2 million and indefinite-lived trademarks for $2.0 million.  

Total accumulated goodwill impairment losses were $156.3 million and $155.6 million at November 30, 2017 and 2016, which comprise the goodwill impairment loss incurred during fiscal 2017 as well as a $14.9 million goodwill impairment loss recorded by our industrial reportable segment during fiscal 2009.

The gross amount of other intangible asset accumulated impairment losses were $53.6 million and $48.4 million at November 30, 2017 and 2016, which comprise the other intangible asset impairment loss of $47.8 million incurred during fiscal 2017 as well as a $0.6 million other intangible asset impairment loss recorded by our industrial reportable segment during fiscal 2009. Additionally, during the third quarter of fiscal 2017, we recorded an impairment loss on an indefinite-lived tradename for approximately $4.9 million, which was recorded by our consumer reportable segment.

As previously reported, we had monitored the performance of our Kirker nail enamel business throughout fiscal 2016.  During the third quarter ended February 29, 2016, we reported that performance shortfalls for Kirker were attributable to a delay in new business.  We performed our annual goodwill impairment analysis during the fourth quarter of fiscal 2016, which resulted in an excess of fair value over carrying value of 8% for our Kirker reporting unit. During the quarter ended August 31, 2016, we reported that while Kirker’s first quarter results were below the comparable prior year period, their performance was in line with expectations, and our assessment of the Kirker business did not indicate the presence of any goodwill impairment triggering events.

For the quarter ended November 30, 2016, we identified certain factors that we considered important in assessing the requirement to perform an interim impairment evaluation for our Kirker reporting unit.  First, Kirker’s three month operating results for the period ended November 30, 2016 were significantly below historical and expected operating results and downward adjustments were recently made regarding our expectations for Kirker’s performance. In the quarter ended November 30, 2016, Kirker experienced market share losses at several key customers, including the loss of its largest customer, which accounted for over 15% of Kirker’s fiscal 2016 sales.  In addition, some problematic customer relationship issues surfaced during the quarter ended November 30, 2016, which resulted in a personnel change in a key leadership position at Kirker.  After considering the totality of these recent events, we determined that an interim step one goodwill impairment assessment was required, as well as an impairment assessment for our intangible and other long-lived assets.  Our testing resulted in the impairment charges outlined above for goodwill and other intangible assets.  

Our goodwill impairment assessment included estimating the fair value of our Kirker reporting unit and comparing it with its carrying amount at November 30, 2016.  Since the carrying amount of Kirker exceeded its fair value, additional steps were required to determine and recognize an impairment loss. Calculating the fair value of a reporting unit requires our significant use of estimates and assumptions, which are generally considered Level 3 inputs based on our review of the fair value hierarchy. We estimated the fair value of our Kirker reporting unit by applying a discounted future cash flow calculation to Kirker’s projected earnings before interest, taxes, depreciation and amortization (“EBITDA”). In applying this methodology, we relied on a number of factors, including actual and forecasted operating results and market data for the nail enamel industry.  Discounted cash flow calculations represent a common measure used to value and buy or sell businesses in our industry.  The discounted cash flow used in the goodwill impairment test for Kirker assumed discrete period revenue growth through fiscal 2021 that was reflective of recent downward revisions to previous expectations for future growth from market opportunities related to contracting with certain retailers to fill nail polish for their respective private label brands as well as downward revisions to growth expectations for the Kirker liquid nail polish business below the expected liquid nail polish growth rates for the markets in which Kirker operates.  In the terminal year we assumed a long-term earnings growth rate of 3.0% that we believe is appropriate given the current industry specific expectations.  As of the valuation date, we utilized a weighted-average cost of capital of 8.0%, which we believed was appropriate as it reflected the relative risk, the time value of money, and was consistent with Kirker’s peer group. After recording the goodwill impairment charge of $140.7 million, no goodwill remained on the Kirker balance sheets as of November 30, 2016.  

Our other intangible asset impairment assessment involved estimating the fair value of each of Kirker’s amortizable intangibles and other long-lived assets as well as the indefinite-lived tradename asset and comparing it with its carrying amount. Measuring a potential impairment of amortizable intangibles and other long-lived assets requires the use of various estimates and assumptions, including the determination of which cash flows are directly related to the assets being evaluated, the respective useful lives over which those cash flows will occur and potential residual values, if any.  As the results of our testing indicated that the carrying values of certain of these assets would not be recoverable, as outlined above, we recorded other intangible asset impairments of approximately $45.7 million for the three and six months ended November 30, 2016.    

Calculating the fair value of the Kirker indefinite-lived tradename required our significant use of estimates and assumptions. We estimated the fair value of Kirker’s indefinite-live tradename by applying a relief-from-royalty calculation, which included discounted future cash flows related to its projected revenues. In applying this methodology, we relied on a number of factors, including actual and forecasted revenues and market data for the nail enamel industry.  As the carrying amount of the tradename exceeded its fair value, the impairment loss of $2.0 million was recorded for the three and six months ended November 30, 2016.

Certain assets and liabilities are subject to nonrecurring fair value measurements, which typically are remeasured at fair value as a result of impairment charges.  As a result of the impairment testing described above, the fair value of Kirker’s identifiable intangible assets and indefinite-lived tradename were recalculated, and the resulting fair value approximated $5.8 million at November 30, 2016.  Based upon our review of the fair value hierarchy, the inputs used in these fair value measurements were considered Level 3 inputs.

Marketable securities, included in other current and long-term assets totaling $102.5 million and $71.3 million at November 30, 2017, respectively, and included in other current and long-term assets totaling $89.5 million and $75.0 million at May 31, 2017, respectively, are composed of available-for-sale securities and are reported at fair value.  We carry a portion of our marketable securities portfolio in long-term assets since they are generally held for the settlement of our general and product liability insurance claims processed through our wholly owned captive insurance subsidiaries.

Marketable securities are composed of available-for-sale securities and are reported at fair value. Realized gains and losses on sales of investments are recognized in net income on the specific identification basis. Changes in the fair values of securities that are considered temporary are recorded as unrealized gains and losses, net of applicable taxes, in accumulated other comprehensive (loss) within stockholders’ equity. Other-than-temporary declines in market value from original cost are reflected in operating income in the period in which the unrealized losses are deemed other than temporary. In order to determine whether other-than-temporary declines in market value have occurred, the duration of the decline in value and our ability to hold the investment are considered in conjunction with an evaluation of the strength of the underlying collateral and the extent to which the investment’s amortized cost or cost, as appropriate, exceeds its related market value.

Gross gains realized on sales of investments were $2.0 million and $1.9 million for the quarters ended November 30, 2017 and 2016, respectively.  During the second quarter of fiscal 2017, we recognized gross realized losses on sales of investments of $0.8 million, while such losses were de minimis during the current fiscal quarter. During the second quarter of fiscal 2017, we recognized losses of approximately $0.2 million for securities deemed to have other-than-temporary impairments, while there were no such losses during the current fiscal quarter.  

Gross gains realized on sales of investments were $6.1 million and $4.7 million for the six months ended November 30, 2017 and 2016, respectively.  During the first half of fiscal 2018 and 2017, we recognized gross realized losses on sales of investments of $1.2 million and $1.0 million, respectively. During the first half of fiscal 2017, we recognized losses of approximately $0.4 million for securities deemed to have other-than-temporary impairments, while there were no such losses during the first half of fiscal 2018.  These amounts are included in investment (income), net in the Consolidated Statements of Income.

Summarized below are the securities we held at November 30, 2017 and May 31, 2017 that were in an unrealized loss position and that were included in accumulated other comprehensive (loss), aggregated by the length of time the investments had been in that position:

	November 30, 2017					May 31, 2017
(In thousands)	Fair Value		Gross Unrealized Losses			Fair Value		Gross Unrealized Losses
Total investments with unrealized losses	$	55,199	$	(2,602	)	$	59,987	$	(3,505	)
Unrealized losses with a loss position for less than 12 months		13,813		(75	)		40,854		(2,983	)
Unrealized losses with a loss position for more than 12 months		41,386		(2,527	)		19,133		(522	)

We have reviewed all of the securities included in the table above and have concluded that we have the ability and intent to hold these investments until their cost can be recovered, based upon the severity and duration of the decline. Therefore, we did not recognize any other-than-temporary impairment losses on these investments. The unrealized losses generally relate to investments whose fair values at November 30, 2017 were less than 15% below their original cost. From time to time, we may experience significant volatility in general economic and market conditions.  If we were to experience unrealized losses that were to continue for longer periods of time, or arise to more significant levels of unrealized losses within our portfolio of investments in marketable securities in the future, we may recognize additional other-than-temporary impairment losses. Such potential losses could have a material impact on our results of operations in any given reporting period. As such, we continue to closely evaluate the status of our investments and our ability and intent to hold these investments.

The net carrying values of debt securities at November 30, 2017, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

Fair Value Disclosures [Abstract]

Fair Value Measurements

NOTE 5 — FAIR VALUE MEASUREMENTS

Financial instruments recorded in the balance sheet include cash and cash equivalents, trade accounts receivable, marketable securities, notes and accounts payable, and debt.

An allowance for anticipated uncollectible trade receivable amounts is established using a combination of specifically identified accounts to be reserved, and a reserve covering trends in collectibility. These estimates are based on an analysis of trends in collectibility and past experience, but are primarily made up of individual account balances identified as doubtful based on specific facts and conditions. Receivable losses are charged against the allowance when we confirm uncollectibility.

The valuation techniques utilized for establishing the fair values of assets and liabilities are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect management’s market assumptions. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value, as follows:

Level 1 Inputs — Quoted prices for identical instruments in active markets.

Level 2 Inputs — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 Inputs — Instruments with primarily unobservable value drivers.

The following tables present our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy.

(In thousands)	QuotedPrices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)			Fair Value at November 30, 2017

Total	$	2,467	$	161,988	$	(17,979	)	$	146,476

Our marketable securities are primarily composed of available-for-sale securities, and are valued using a market approach. The availability of inputs observable in the market varies from instrument to instrument and depends on a variety of factors including the type of instrument, whether the instrument is actively traded, and other characteristics particular to the transaction. For most of our financial instruments, pricing inputs are readily observable in the market, the valuation methodology used is widely accepted by market participants, and the valuation does not require significant management discretion. For other financial instruments, pricing inputs are less observable in the market and may require management judgment.

The contingent consideration represents the estimated fair value of the additional variable cash consideration payable in connection with recent acquisitions that is contingent upon the achievement of certain performance milestones. We estimated the fair value using expected future cash flows over the period in which the obligation is expected to be settled, and applied a discount rate that appropriately captures a market participant's view of the risk associated with the obligation, which are considered to be Level 3 inputs. During the first half of fiscal 2018, we paid approximately $3.3 million for settlements of contingent consideration obligations relating to certain performance milestones that were established in prior periods and achieved during the current period.  During the first half of fiscal 2017, we paid approximately $4.1 million for settlements of contingent consideration obligations relating to certain performance milestones that were established in prior periods and achieved during last year’s first half. These amounts are reported in payments of acquisition-related contingent consideration in cash flows from financing activities in the Consolidated Statements of Cash Flows.  

The carrying value of our current financial instruments, which include cash and cash equivalents, marketable securities, trade accounts receivable, accounts payable and short-term debt approximates fair value because of the short-term maturity of these financial instruments. At November 30, 2017 and May 31, 2017, the fair value of our long-term debt was estimated using active market quotes, based on our current incremental borrowing rates for similar types of borrowing arrangements, which are considered to be Level 2 inputs. Based on the analysis performed, the fair value and the carrying value of our financial instruments and long-term debt as of November 30, 2017 and May 31, 2017 are as follows:

	At November 30, 2017

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivatives and Hedging

NOTE 6 - DERIVATIVES AND HEDGING

Derivative Instruments and Hedging Activities

We are exposed to market risks, such as changes in foreign currency exchange rates and interest rates. To manage the volatility related to these exposures, from time to time, we enter into various derivative transactions. We use various types of derivative instruments including forward contracts and swaps. We formally assess, designate and document, as a hedge of an underlying exposure, each qualifying derivative instrument that will be accounted for as an accounting hedge at inception. Additionally, we assess, both at inception and at least quarterly thereafter, whether the financial instruments used in the hedging transaction are effective at offsetting changes in either the fair values or cash flows of the underlying exposures.

Net Investment Hedge

In October 2017, as a means of mitigating the impact of currency fluctuations on our Euro investments in foreign entities, we executed a fair value hedge and two cross currency swaps, in which we will pay variable rate interest in Euros and receive fixed rate interest in U.S. Dollars with a combined notional amount of approximately €85.25 million ($100 million U.S. Dollar equivalent), and which have a maturity date of November 2022. This effectively converts a portion of our U.S. Dollar denominated fixed rate debt to Euro denominated variable rate debt. The fair value hedge is recognized at fair value in our Consolidated Balance Sheets, while changes in the fair value of the hedge are recognized in interest expense in our Consolidated Statements of Income. We designated the swaps as net investment hedges of our net investment in our European operations under ASU 2017-12 and applied the spot method to these hedges. The changes in fair value of the derivative instruments that are designated and qualify as hedges of net investments in foreign operations are recognized in accumulated other comprehensive income (“AOCI”) to offset the changes in the values of the net investments being hedged.  Amounts released from AOCI and reclassified into interest expense did not have a material impact on our Consolidated Financial Statements for any period presented.

Derivatives Designated as Cash Flow Hedging Instruments

We have designated certain forward contracts as hedging instruments pursuant to ASC No. 815 (“ASC 815”), “Derivatives and Hedging.” Changes in the fair value of these highly effective hedges are recorded as a component of AOCI. During the period in which a forecasted transaction affects earnings, amounts previously recorded as a component of AOCI are reclassified into earnings as a component of cost of sales.  Amounts released from AOCI and reclassified into earnings did not have a material impact on our Consolidated Financial Statements for any period presented. As of November 30, 2017, and May 31, 2017 the notional amount of the forward contracts held to sell international currencies was $14.6 million and $9.8 million, respectively.

Derivatives Not Designated as Hedges

At November 30, 2017, we held three foreign currency forward contracts designed to reduce our exposure to changes in the cash flows of intercompany foreign-currency-denominated loans related to changes in foreign currency exchange rates by fixing the functional currency cash flows.  These contracts have not been designated as hedges; therefore, the changes in fair value of these derivatives are recognized in earnings as a component of other (income) expense. Amounts recognized in earnings did not have a material impact on our Consolidated Financial Statements for any period presented. As of November 30, 2017 and May 31, 2017, the notional amounts of the forward contracts held to purchase foreign currencies was $151.7 million and $49.4 million, respectively.

Disclosure about Derivative Instruments

All of our derivative assets and liabilities measured at fair value are classified as Level 2 within the fair value hierarchy. We determine the fair value of our derivatives based on valuation methods, which project future cash flows and discount the future amounts to present value using market based observable inputs, including interest rate curves, foreign currency rates, as well as future and basis point spreads, as applicable.

The fair values of qualifying and non-qualifying instruments used in hedging transactions as of November 30, 2017 and May 31, 2017 are as follows:

Income Taxes

NOTE 9 — INCOME TAXES

The effective income tax expense rate was 12.2% for the three months ended November 30, 2017 compared to an effective income tax benefit rate of 34.3% for the three months ended November 30, 2016.  The effective income tax expense rate was 19.6% for the six months ended November 30, 2017 compared to an effective income tax benefit rate of 3.7% for the six months ended November 30, 2016.

The effective tax rate for the three months ended November 30, 2017 and 2016 reflect variances from the 35% federal statutory rate due to lower effective tax rate of certain of our foreign subsidiaries, the benefit of the domestic manufacturing deduction, partially offset by the unfavorable impact of state and local taxes. Additionally, we recorded favorable discrete tax adjustments for excess tax benefits related to equity compensation of $2.0 million and $1.0 million, respectively, in the three-month periods ended November 30, 2017 and 2016; and $3.5 million and $11.3 million, respectively, for the six month periods ended November 30, 2017 and 2016.

Additionally, during the three-month period ended November 30, 2017, we approved and completed a foreign legal entity restructuring and corresponding planning strategy that resulted in a discrete tax benefit of $18.0 million. Of this amount, a U.S. tax benefit of $1.2 million resulted from the generation of foreign tax credits which offset a deemed inclusion in U.S. taxable income of foreign earnings.  The planned subsequent distribution of these foreign earnings resulted in a benefit of $16.8 million for a corresponding reduction in the estimated deferred income tax liability for the U.S. tax cost associated with unremitted foreign earnings that are not considered permanently reinvested.

Furthermore, income tax expense for the six-month period ended November 30, 2017 reflects the net discrete tax benefit of $9.0 million that we previously reported during the three-month period ended August 31, 2017.  As of November 30, 2017, the amount of unremitted foreign earnings, not previously subject to U.S. tax that may be repatriated and the corresponding deferred tax liability have been adjusted to $221.8 million and $63.4 million, respectively. The reduction to the amount of unremitted foreign earnings that may be repatriated, and the related tax impact, is principally the result of the above noted transaction related to the foreign earnings not considered permanently reinvested, partially offset by the impact of foreign currency translation. The increase to the deferred tax liability related to foreign currency translation was recorded as a component of accumulated other comprehensive income.

We have not provided for U.S. income and foreign withholding taxes on the remaining foreign subsidiaries’ undistributed earnings because such earnings have been retained and reinvested by the subsidiaries as of November 30, 2017.  Accordingly, no provision has been made for U.S. income taxes or foreign withholding taxes, which may become payable if the remaining undistributed earnings of foreign subsidiaries were paid to us as dividends.

On December 22, 2017, the Tax Cuts and Jobs Act (the “Act”) was enacted into law.  The income tax effects of changes in tax laws are recognized in the period when enacted. The Act provides for numerous significant tax law changes and modifications with varying effective dates, which include reducing the corporate income tax rate from 35% to 21%, creating a territorial tax system (with a one-time mandatory tax on previously deferred foreign earnings), broadening the tax base and allowing for immediate capital expensing of certain qualified property.

As a fiscal year-end taxpayer, certain provisions of the Act will begin to impact us in our fiscal third quarter ending February 28, 2018, while other provisions will impact us beginning in fiscal 2019. The corporate tax rate reduction is effective for RPM as of January 1, 2018 and, accordingly, will reduce our current fiscal year federal statutory rate to a blended rate of approximately 29.2%.

We are currently analyzing the various components of the Act and its impact on our financial statements, including the estimated impact resulting from the re-measurement of our deferred tax assets and liabilities and the estimated charge for the one-time tax on our deferred foreign earnings and expect to record provisional amounts for these impacts in our third quarter financial statements.

We regularly assess our permanent reinvestment assertion regarding undistributed foreign earnings.  The Act includes other provisions that may factor into our reinvestment assertions.  Any prospective changes in our assertions regarding permanent reinvestment of undistributed earnings will be recorded in the period of the change.

Stock Repurchase Program

NOTE 11 — STOCK REPURCHASE PROGRAM

On January 8, 2008, we announced our authorization of a stock repurchase program under which we may repurchase shares of RPM International Inc. common stock at management’s discretion for general corporate purposes. Our current intent is to limit our repurchases only to amounts required to offset dilution created by stock issued in connection with our equity-based compensation plans, or approximately one to two million shares per year. As a result of this authorization, we may repurchase shares from time to time in the open market or in private transactions at various times and in amounts and for prices that our management deems appropriate, subject to insider trading rules and other securities law restrictions. The timing of our purchases will depend upon prevailing market conditions, alternative uses of capital and other factors. We may limit or terminate the repurchase program at any time. During the three and six month periods ended November 30, 2017 and 2016, we did not repurchase any shares of our common stock under this program.

(2) Restricted shares totaling 123,262 and 99,612 for the three and six months ended November 30, 2017, respectively, were excluded from the calculation of diluted earnings per share because the grant price of the restricted shares exceeded the average market price of the shares during the period and their effect, accordingly, would have been anti-dilutive. There were 243,000 shares of restricted stock identified as being anti-dilutive for the three months ended November 30, 2016; and none identified as being anti-dilutive for the six months ended November 30, 2016. In addition, stock appreciation rights (“SARs”) totaling 600,000 for the three and six months ended November 30, 2017, and 1,170,000 for the three and six months ended November 30, 2016, were excluded from the calculation of diluted earnings per share as their effect would have been anti-dilutive.

The decrease in pension and postretirement benefit cost from fiscal 2017 to 2018 reflects the impact of increased asset values, which we expect will generate higher returns, and a change in estimate for lump sum valuations. We expect that pension expense will fluctuate on a year-to-year basis, depending upon the investment performance of plan assets and potential changes in interest rates, but such changes are not expected to be material to our consolidated financial results. We previously disclosed in our financial statements for the fiscal year ended May 31, 2017 that we expected to contribute approximately $1.0 million to our retirement plans in the U.S. and approximately $7.0 million to plans outside the U.S. during the current fiscal year. As of November 30, 2017, this has not changed.

Commitments And Contingencies Disclosure [Abstract]

Contingencies and Other Accrued Losses

NOTE 14 – CONTINGENCIES AND OTHER ACCRUED LOSSES

We provide, through our wholly owned insurance subsidiaries, certain insurance coverage, primarily product liability coverage, to our other subsidiaries. Excess coverage is provided by third-party insurers. Our product liability accruals provide for these potential losses as well as other uninsured claims.  Product liability accruals are established based upon actuarial calculations of potential liability using industry experience, actual historical experience and actuarial assumptions developed for similar types of product liability claims, including development factors and lag times.  To the extent there is a reasonable possibility that potential losses could exceed the amounts already accrued, we believe that the amount of any such additional loss would be immaterial to our results of operations, liquidity and consolidated financial position.

We also offer warranties on many of our products, as well as long-term warranty programs at certain of our businesses, and have established product warranty liabilities. We review these liabilities for adequacy on a quarterly basis and adjust them as necessary. The primary factors that could affect these liabilities may include changes in performance rates as well as costs of replacement. Provision for estimated warranty costs is recorded at the time of sale and periodically adjusted, as required, to reflect actual experience. It is probable that we will incur future losses related to warranty claims we have received but that have not been fully investigated and related to claims not yet received. While our warranty liabilities represent our best estimates at November 30, 2017, we can provide no assurances that we will not experience material claims in the future or that we will not incur significant costs to resolve such claims beyond the amounts accrued or beyond what we may recover from our suppliers. Based upon the nature of the expense, product warranty expense is recorded as a reduction of sales, as a component of cost of sales, or within selling, general and administrative expense.

Also, due to the nature of our businesses, the amount of claims paid can fluctuate from one period to the next.  While our warranty liabilities represent our best estimates of our expected losses at any given time, from time-to-time we may revise our estimates based on our experience relating to factors such as weather conditions, specific circumstances surrounding product installations and other factors.

The following table includes the changes in our accrued warranty balances:

Ending Balance	$	14,457		$	15,954		$	14,457		$	15,954

(1) Primarily claims paid during the year.

In addition, like other companies participating in similar lines of business, some of our subsidiaries are involved in proceedings relating to environmental matters.  It is our policy to accrue remediation costs when it is probable that such efforts will be required and the related costs can be reasonably estimated.  These liabilities are undiscounted and are not material to our financial statements during any of the periods presented.

We were notified by the SEC on June 24, 2014, that we are the subject of a formal investigation pertaining to the timing of our disclosure and accrual of loss reserves in fiscal 2013 with respect to the previously disclosed U.S. Department Of Justice (the “DOJ”) and the U.S. General Services Administration (the “GSA”) Office of Inspector General investigation into compliance issues relating to Tremco Roofing Division’s GSA contracts. As previously disclosed, our audit committee completed an investigation into the facts and circumstances surrounding the timing of our disclosure and accrual of loss reserves with respect to the GSA and DOJ investigation, and determined that it was appropriate to restate our financial results for the first, second and third quarters of fiscal 2013.  These restatements had no impact on our audited financial statements for the fiscal years ended May 31, 2013 or 2014. The audit committee’s investigation concluded that there was no intentional misconduct on the part of any of our officers.

In connection with the foregoing, on September 9, 2016, the SEC filed an enforcement action against us and our General Counsel.  We have cooperated with the SEC’s investigation and believe the allegations in the complaint mischaracterize both our and our General Counsel’s actions in connection with the matters related to our quarterly results in fiscal 2013 and are without merit.  Both we and our General Counsel filed motions to dismiss the complaint on February 24, 2017.  Those motions to dismiss the complaint were denied by the Court on September 29, 2017.  We and our General Counsel filed answers to the complaint on October 16, 2017.  No trial date has been set, but formal discovery will commence in January 2018.  We intend to continue to contest the allegations in the complaint vigorously.

The action by the SEC could result in sanctions against us and/or our General Counsel and could impose substantial additional costs and distractions, regardless of its outcome. We have determined that it is probable that we will incur a loss relating to this matter and have estimated a range of potential loss. We have accrued at the low end of the range of loss, as no amount within the range is more likely to occur, and no amount within the estimated range of loss would have a material impact on our consolidated financial condition, results of operations or cash flows.

With respect to a case pending against one of our subsidiaries in which there is alleged both trade secret and trademark infringement, during the quarter ended August 31, 2017, the court denied our motion for summary judgment and based on our current understanding of the claim we have determined that it is reasonably possible that we may incur a loss related to this claim; however we cannot estimate the amount or range of any potential loss.

Segment Reporting [Abstract]

Segment Information

NOTE 16 — SEGMENT INFORMATION

We operate a portfolio of businesses and product lines that manufacture and sell a variety of specialty paints, protective coatings and roofing systems, sealants and adhesives. We manage our portfolio by organizing our businesses and product lines into three reportable segments: the industrial reportable segment, the consumer reportable segment and the specialty reportable segment. Within each reportable segment, we aggregate operating segments or product lines that consist of individual companies or groups of companies and product lines, which generally address common markets, share similar economic characteristics, utilize similar technologies and can share manufacturing or distribution capabilities. Our seven operating segments represent components of our business for which separate financial information is available that is utilized on a regular basis by our chief operating decision maker in determining how to allocate the assets of the company and evaluate performance. These seven operating segments are each managed by an operating segment manager, who is responsible for the day-to-day operating decisions and performance evaluation of the operating segment’s underlying businesses.

Our industrial reportable segment products are sold throughout North America and also account for the majority of our international sales. Our industrial product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. The industrial reportable segment comprises three separate operating segments — Tremco Group, tremco illbruck Group and Performance Coatings Group. Products and services within this reportable segment include construction chemicals, roofing systems, weatherproofing and other sealants, and polymer flooring.

Our consumer reportable segment manufactures and markets professional use and do-it-yourself (“DIY”) products for a variety of mainly consumer applications, including home improvement and personal leisure activities. Our consumer segment’s major manufacturing and distribution operations are located primarily in North America, along with a few locations in Europe and other parts of the world. Our consumer reportable segment products are primarily sold directly to mass merchandisers, home improvement centers, hardware stores, paint stores, craft shops, cosmetic companies and through distributors. This reportable segment comprises three operating segments — Rust-Oleum Group, DAP Group and SPG-Consumer Group. Products within this reportable segment include specialty, hobby and professional paints; nail enamels; caulks; adhesives; silicone sealants and wood stains.

Our specialty reportable segment products are sold throughout North America and a few international locations, primarily in Europe. Our specialty product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. The specialty reportable segment is a single operating segment, which offers products that include industrial cleaners, restoration services equipment, colorants, exterior finishes, edible coatings and specialty glazes for pharmaceutical and food industries, and other specialty OEM coatings.

In addition to our three reportable segments, there is a category of certain business activities and expenses, referred to as corporate/other, that does not constitute an operating segment. This category includes our corporate headquarters and related administrative expenses, results of our captive insurance companies, gains or losses on the sales of certain assets and other expenses not directly associated with any reportable segment. Assets related to the corporate/other category consist primarily of investments, prepaid expenses and headquarters’ property and equipment. These corporate and other assets and expenses reconcile reportable segment data to total consolidated income before income taxes and identifiable assets.

We reflect income from our joint ventures on the equity method, and receive royalties from our licensees.

The following tables reflect the results of our reportable segments consistent with our management philosophy, and represent the information we utilize, in conjunction with various strategic, operational and other financial performance criteria, in evaluating the performance of our portfolio of businesses.

New Accounting Pronouncements (Policies)

6 Months Ended

Accounting Changes And Error Corrections [Abstract]

New Accounting Pronouncements

NEW ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” which establishes a comprehensive revenue recognition standard that will supersede nearly all existing revenue recognition guidance under GAAP. The new standard prescribes a five-step model for recognizing revenue, which will require significant judgment in its application. The new standard requires disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

Under the original issuance, the new standard would have applied to annual periods beginning after December 15, 2016, including interim periods therein. However, in August 2015, the FASB issued ASU 2015-14, which extends the standard effective date by one year and includes an option to apply the standard on the original effective date. The provisions of this ASU may be applied retrospectively to each prior reporting period presented, or on a modified retrospective basis by recognizing a cumulative catch-up transition amount at the date of initial application. We have selected the modified retrospective transition method, which we will apply upon adoption of the standard as of June 1, 2018.

Given the scope of work required to implement the recognition and disclosure requirements under the new standard, we began our assessment process during fiscal 2016.  Our progress to date includes a preliminary identification of areas which will require changes to policies, processes, systems or internal controls.  We expect revenue recognition for our broad portfolio of products and services to remain largely unchanged. However, the guidance is expected to change the timing of revenue recognition in certain areas, including our accounting for long-term construction contracts. While these impacts are not expected to be material to our overall Consolidated Financial Statements, we do anticipate that the new disclosure requirements surrounding revenue recognition will be significant. We continue to assess all potential impacts of the guidance and given the stage of our adoption procedures as well as our normal ongoing business dynamics, our preliminary conclusions and assessments of the potential impacts on each of our different business units’ revenue streams are subject to change.  

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which increases lease transparency and comparability among organizations.  Under the new standard, lessees will be required to recognize all assets and liabilities arising from leases on the balance sheet, with the exception of leases with a term of 12 months or less, which permits a lessee to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities.  ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and early adoption is permitted. The new standard requires the recognition and measurement of leases at the beginning of the earliest period presented using a modified retrospective approach, which includes a number of optional practical expedients that entities may elect to apply.  We are currently evaluating the impact this guidance will have on our Consolidated Financial Statements. At a minimum, total assets and total liabilities will increase in the period the ASU is adopted.  At November 30, 2017, our total undiscounted future minimum payments outstanding for operating lease obligations approximated $214.0 million.  

In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which makes a number of changes meant to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows.  The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted.  Upon adoption, entities must apply the guidance retrospectively to all periods presented.  We are currently evaluating the impact this guidance will have on our Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations: Clarifying the Definition of a Business,” with the objective of adding guidance to assist entities in evaluating whether transactions should be accounted for as acquisitions (disposals) of assets or of businesses. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. We are currently reviewing the impact this revised guidance will have on our Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” to eliminate step two from the goodwill impairment test in order to simplify the subsequent measurement of goodwill. The guidance is effective for fiscal years beginning after December 15, 2019. Early application is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Adoption of this guidance is not expected to have a material impact on our Consolidated Financial Statements.  

In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented.  The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years.  We are currently reviewing the impact this guidance will have on our Consolidated Financial Statements.  

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities,” which simplifies hedge accounting through changes to both designation and measurement requirements.  For hedges that qualify as highly effective, the new standard eliminates the requirement to separately measure and record hedge ineffectiveness, resulting in better alignment between the presentation of the effects of the hedging instrument and the hedged item in the financial statements.  ASU No. 2017-12 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  Early adoption is permitted in any interim period after issuance of the update.  Our early adoption of this pronouncement during our current quarter ended November 30, 2017 did not have a material impact on our Consolidated Financial Statements.  Refer to Note 6, “Derivatives and Hedging,” for further information.

The following table sets forth the reconciliation of the numerator and denominator of basic and diluted earnings per share, as calculated using the treasury stock method for the three months ended November 30, 2016 and the two-class method for the six months ended November 30, 2016.  For the three and six months ended November 30, 2017, basic and diluted earnings per share were calculated using the two-class method.

(1) Represents the number of shares that would be issued if our contingently convertible notes were converted.  We include these shares in the calculation of diluted EPS as the conversion of the notes may be settled, at our election, in cash, shares of our common stock, or a combination of cash and shares of our common stock.  

(2) Restricted shares totaling 123,262 and 99,612 for the three and six months ended November 30, 2017, respectively, were excluded from the calculation of diluted earnings per share because the grant price of the restricted shares exceeded the average market price of the shares during the period and their effect, accordingly, would have been anti-dilutive. There were 243,000 shares of restricted stock identified as being anti-dilutive for the three months ended November 30, 2016; and none identified as being anti-dilutive for the six months ended November 30, 2016. In addition, stock appreciation rights (“SARs”) totaling 600,000 for the three and six months ended November 30, 2017, and 1,170,000 for the three and six months ended November 30, 2016, were excluded from the calculation of diluted earnings per share as their effect would have been anti-dilutive.

We include these shares in the calculation of diluted EPS as the conversion of the notes may be settled, at our election, in cash, shares of our common stock, or a combination of cash and shares of our common stock.

[2] Restricted shares totaling 123,262 and 99,612 for the three and six months ended November 30, 2017, respectively, were excluded from the calculation of diluted earnings per share because the grant price of the restricted shares exceeded the average market price of the shares during the period and their effect, accordingly, would have been anti-dilutive. There were 243,000 shares of restricted stock identified as being anti-dilutive for the three months ended November 30, 2016; and none identified as being anti-dilutive for the six months ended November 30, 2016. In addition, stock appreciation rights (“SARs”) totaling 600,000 for the three and six months ended November 30, 2017, and 1,170,000 for the three and six months ended November 30, 2016, were excluded from the calculation of diluted earnings per share as their effect would have been anti-dilutive.
