NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

A. ACCOUNTING POLICIES

In our opinion, the accompanying unaudited condensed consolidated financial statements contain all adjustments, of a normal recurring nature, necessary to fairly state our financial position at June 30, 2018, our results of operations and comprehensive income (loss) for the three-month and six-month periods ended June 30, 2018 and 2017, and cash flows and changes in shareholders' equity for the six-month periods ended June 30, 2018 and 2017. The condensed consolidated balance sheet at December 31, 2017 was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

Reclassification. Certain prior year amounts have been reclassified to conform to the 2018 presentation in the condensed consolidated financial statements. 

Income Tax Effects within Accumulated Other Comprehensive Income (Loss). The accounting guidance for income taxes requires us to allocate our provision for income taxes between continuing operations and other categories of earnings, such as other comprehensive income (loss). Subsequent adjustments to deferred taxes originally recorded to other comprehensive income (loss) may reverse in a different category of earnings, such as continuing operations, resulting in a disproportionate tax effect within accumulated other comprehensive income (loss). Generally, a disproportionate tax effect will be eliminated and recognized in income tax expense (benefit) when the circumstances upon which it is premised cease to exist.

The disproportionate tax effect related to various defined-benefit pension plans will be eliminated from accumulated other comprehensive income (loss) at the termination of the related pension plans. The disproportionate tax effect relating to our interest rate swap hedge, which was terminated in 2012, will be eliminated from accumulated other comprehensive income (loss) upon the maturity of the related debt in March 2022.

Recently Adopted Accounting Pronouncements. In May 2014, the Financial Accounting Standards Board ("FASB") issued a new standard for revenue recognition, Accounting Standards Codification ("ASC") 606. The purpose of ASC 606 is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability across industries. We adopted ASC 606 on January 1, 2018, under the full retrospective method of adoption. As a result of this adoption, net sales increased by $9 million and $10 million for the three-month and six-month periods ended June 30, 2017, respectively, and operating profit (and income before income taxes) increased by $7 million and $4 million for the three-month and six-month periods ended June 30, 2017, respectively, from what was previously reported. For full year 2017 and 2016, net sales decreased by $2 million and increased by $4 million, respectively, and operating profit (and income before income taxes) decreased by $1 million and increased by $2 million, respectively, from what was previously reported. We additionally have recasted our previously reported segment operating results at the end of this section.

In January 2016, the FASB issued ASU 2016-01, "Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities," which primarily affects the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. We adopted ASU 2016-01 on January 1, 2018. The adoption of this standard did not have a material impact on our financial position or results of operations.

In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Asset Transfers of Assets Other than Inventory," which no longer allows the tax effects of intra-entity asset transfers (intercompany sales) of assets other than inventory to be deferred until the transferred asset is sold to a third party or otherwise recovered through use. The new standard requires the tax expense from the sale of the asset in the seller's tax jurisdiction and the corresponding basis differences in the buyer's jurisdiction to be recognized when the transfer occurs even though the pre-tax effects of the transaction are eliminated in consolidation. We adopted ASU 2016-16 on January 1, 2018. The adoption of this standard did not have a material impact on our financial position or results of operations.

A. ACCOUNTING POLICIES (Continued)

In March 2017, the FASB issued ASU 2017-07, "Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which modifies the presentation of net periodic pension and post-retirement benefit cost ("net benefit cost") in the income statement and the components eligible for capitalization as assets. ASU 2017-07 requires retrospective application for certain aspects of the standard. We adopted ASU 2017-07 on January 1, 2018. As a result of the adoption, we reclassified $8 million and $15 million of net benefit cost from operating profit to other income (expense), net, within our results of operations for the three-month and six-month periods ended June 30, 2017, respectively. For full year 2017 and 2016, we reclassified $26 million and $32 million, respectively, of net benefit cost from operating profit to other income (expense), net, within our results of operations. We additionally have recasted our previously reported segment operating results at the end of this section. The adoption of the standard did not impact income before income taxes.

In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting," which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. We adopted ASU 2017-09 on January 1, 2018. The adoption of this standard did not impact our financial position or results of operations; however, modification accounting is now required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions.

In February 2018, the FASB issued ASU 2018-02, "Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which permits a company to reclassify from accumulated other comprehensive income (loss) to retained earnings the disproportionate tax effects resulting from the Tax Cuts and Jobs Act of 2017 (“2017 Act”). We early adopted ASU 2018-02 on March 31, 2018. As a result of the adoption, in the first quarter of 2018 we decreased accumulated other comprehensive income (loss) and increased retained earnings (deficit) by the $59 million disproportionate tax effect caused by the 2017 Act.

Impact of Adoption of ASC 606 and ASU 2017-07. The recasted impact of the adoptions of ASC 606 and ASU 2017-07 to our previously reported operating results and basic and diluted income per share was as follows, in millions (except per common share data):

Recently Issued Accounting Pronouncements. In February 2016, the FASB issued a new standard for leases, ASC 842, which changes the accounting model for identifying and accounting for leases. ASC 842 is effective for us for annual periods beginning January 1, 2019. We expect this standard to increase our total assets and total liabilities; however, we are currently evaluating the magnitude of the impact. We do not expect the standard to have a material impact on our results of operations. In preparation for the adoption of the standard, we have procured a third-party software to track and manage our leases and have trained our business units on the new standard and the use of the software.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," which modifies the methodology for recognizing loss impairments on certain types of financial instruments, including receivables. The new methodology requires an entity to estimate the credit losses expected over the life of an exposure. Additionally, ASU 2016-13 amends the current available-for-sale security other-than-temporary impairment model for debt securities. ASU 2016-13 is effective for us for annual periods beginning January 1, 2020. We are currently evaluating the impact the adoption of this new standard will have on our financial position and results of operations.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities," which improves and simplifies accounting rules around hedge accounting and better portrays the economic results of an entity's risk management activities in its financial statements. ASU 2017-12 is effective for us for annual periods beginning January 1, 2019. We are currently evaluating the impact the adoption of this new standard will have on our financial position and results of operations.

In June 2018, the FASB issued ASU 2018-07, "Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting," which modifies the accounting for share-based payment awards issued to nonemployees to largely align it with the accounting for share-based payment awards issued to employees. ASU 2018-07 is effective for us for annual periods beginning January 1, 2019. We do not expect the adoption of the standard will impact our financial position or results of operations.

B. ACQUISITIONS

On March 9, 2018, we acquired substantially all of the net assets of The L.D. Kichler Co. ("Kichler"), a leader in decorative residential and light commercial lighting products, ceiling fans and LED lighting systems. This business expands our product offerings to our customers. The results of this acquisition for the period from the acquisition date are included in the condensed consolidated financial statements and are reported in the Decorative Architectural Products segment. For the three-month and six-month periods endedJune 30, 2018, we recorded $108 million and $135 million, respectively, of net sales as a result of this acquisition. The purchase price, net of $2 million cash acquired, consisted of $548 million paid at closing with cash on hand.

During the three-month period ended June 30, 2018, we revised the allocation of the purchase price to identifiable assets and liabilities based on analysis of information as of the acquisition date that has been made available through June 30, 2018.  Receipt of additional information to complete such analysis and finalization of the valuation is still in process, and, as a result, the allocation will continue to be updated through the measurement period, if necessary.  The preliminary allocation of the fair value of the acquisition of Kichler is summarized in the following table, in millions.

	Initial			Revised
Receivables	$	101		$	101
Inventories	173			169
Other current assets	5			5
Property and equipment	33			33
Goodwill	46			55
Other intangible assets	243			240
Accounts payable	(24		)	(24		)
Accrued liabilities	(25		)	(27		)
Other liabilities	(4		)	(4		)
Total	$	548		$	548

The goodwill acquired, which is generally tax deductible, is related primarily to the operational and financial synergies we expect to derive from combining Kichler's operations into our business, as well as the assembled workforce. The other intangible assets acquired consist of $59 million of indefinite-lived intangible assets, which is related to trademarks, and $181 million of definite-lived intangible assets. The definite-lived intangible assets consist of $145 million related to customer relationships, which is being amortized on a straight-line basis over 20 years, and $36 million of other definite-lived intangible assets, which is being amortized over a weighted-average amortization period of 3 years.

C. DIVESTITURES

In the second quarter of 2017 we divested of Arrow Fastener Co., LLC ("Arrow"), a manufacturer and distributor of fastening tools, for proceeds of $126 million. In connection with the divestiture we recognized a gain of $49 million, included in other, net, within other income (expense), net in our condensed consolidated statement of operations. The results of this business are included within income before income taxes in the condensed consolidated statement of operations and reported as part of our Windows and Other Specialty Products segment prior to the date of the divestiture.

D. REVENUE

We recognize revenue as control of our products is transferred to our customers, which is generally at the time of shipment or upon delivery based on the contractual terms with our customers, or when services are completed. Control over certain of our custom-made window products transfers to our customers as production is completed, and revenue is recognized over the production period for these products, as our products do not have an alternative use and we have an enforceable right to payment during the production period. The production period of our custom-made window products generally does not lapse days, and for these products we currently recognize revenue based on the output of production, which is a faithful depiction of the transfer of these products to our customers. Our customers' payment terms generally range from 30 to 65 days of fulfilling our performance obligations and recognizing revenue.

We consider shipping and handling activities performed by us as activities to fulfill the sales of our products. Amounts billed for shipping and handling are included in net sales, while costs incurred for shipping and handling are included in cost of sales. We capitalize incremental costs of obtaining a contract and expense the costs on a straight-line basis over the contractual period if the cost is recoverable, the cost would not have been incurred without the contract and the term of the contract is greater than one year; otherwise, we expense the amounts as incurred. We do not adjust the promised amount of consideration for the effects of a financing component if the period between when we transfer our products or services and when our customers pay for our products or services is expected to be one year or less.

Our revenues are derived primarily from sales to customers in North America and Internationally, principally Europe. Net sales from these geographic markets, by segment, were as follows, in millions:

We provide customer programs and incentive offerings, including special pricing and co-operative advertising arrangements, promotions and other volume-based incentives. These customer programs and incentives are considered variable consideration. We include in revenue variable consideration only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the variable consideration is resolved. This determination is made based upon known customer program and incentive offerings at the time of sale, and expected sales volume forecasts as it relates to our volume-based incentives. This determination is updated each reporting period. We recognized$6 millionand$3 million for the three-month and six-month periods endedJune 30, 2018, respectively, and $8 million and $7 million for the three-month and six-month periods endedJune 30, 2017, respectively, of revenue related to performance obligations settled in previous periods.

Certain product sales include a right of return. We estimate future product returns at the time of sale based on historical experience and record a corresponding refund liability. We additionally record an asset, based on historical experience, for the amount of product we expect to return to inventory as a result of the return, which is recorded in prepaid expenses and other in the condensed consolidated balance sheets.

We record contract assets for items for which we have satisfied our performance obligation but our receipt of payment is contingent upon delivery or other circumstances other than the passage of time. Our contract assets are recorded in prepaid expenses and other in our condensed consolidated balance sheets. Our contract assets generally

become unconditional and are reclassified to receivables in the quarter subsequent to each balance sheet date. Our contract asset balance was $14 million and $11 million at June 30, 2018 and December 31, 2017, respectively.

We record contract liabilities primarily for deferred revenue. Our contract liabilities are recorded in accrued liabilities in our condensed consolidated balance sheets. Our contract liabilities are generally recognized to net sales in the immediately subsequent reporting period. Our contract liability balance was $13 million and $32 million at June 30, 2018 and December 31, 2017, respectively.

E. DEPRECIATION AND AMORTIZATION

Depreciation and amortization expense was $74 million and $64 million for the six-month periods endedJune 30, 2018 and 2017, respectively.

The carrying value of our other indefinite-lived intangible assets was $199 million and $140 million at June 30, 2018 and December 31, 2017, respectively, and principally included registered trademarks. The carrying value of our definite-lived intangible assets was $218 million (net of accumulated amortization of $18 million) and $47 million (net of accumulated amortization of $10 million) at June 30, 2018 and December 31, 2017, respectively, and principally included customer relationships. The increase in our indefinite-lived intangible assets and definite-lived intangible assets is primarily a result of our acquisition of Kichler.

G. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

We are exposed to global market risk as part of our normal, daily business activities. To manage these risks, we enter into various derivative contracts. These contracts may include interest rate swap agreements and foreign currency contracts. We review our hedging program, derivative positions and overall risk management on a regular basis.

Interest Rate Swap Agreements. In 2012, in connection with the issuance of $400 million of debt, we terminated the interest rate swap hedge relationships that we had entered into in 2011. These interest rate swaps were designated as cash flow hedges and effectively fixed interest rates on the forecasted debt issuance to variable rates based on 3-month LIBOR. Upon termination, the ineffective portion of the cash flow hedges of an approximate $2 million loss was recognized in our consolidated statement of operations in other, net, within other income (expense), net. The remaining loss of approximately $23 million from the termination of these swaps is being amortized as an increase to interest expense over the remaining term of the debt, through March 2022. At June 30, 2018, the balance remaining in accumulated other comprehensive loss was $7 million (pre-tax).

G. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES (Concluded)

Foreign Currency Contracts. Our net cash inflows and outflows exposed to the risk of changes in foreign currency exchange rates arise from the sale of products in countries other than the manufacturing source, foreign currency denominated supplier payments, debt and other payables, and investments in subsidiaries. To mitigate this risk, we, including certain of our European operations, enter into foreign currency forward contracts and foreign currency exchange contracts.

Gains (losses) related to foreign currency forward and exchange contracts are recorded in our condensed consolidated statement of operations in other income (expense), net. In the event that the counterparties fail to meet the terms of the foreign currency forward or exchange contracts, our exposure is limited to the aggregate foreign currency rate differential with such institutions.

The pre-tax gains (losses) included in our condensed consolidated statements of operations were as follows, in millions:

I. DEBT

On April 16, 2018, we repaid and retired all of our $114 million, 6.625% Notes on the scheduled repayment date.    

On June 21, 2017, we issued $300 million of 3.5% Notes due November 15, 2027 and $300 million of 4.5% Notes due May 15, 2047. We received proceeds of $599 million, net of discount, for the issuance of these Notes. The Notes are senior indebtedness and are redeemable at our option at the applicable redemption price. On June 27, 2017, proceeds from the debt issuances, together with cash on hand, were used to repay and early retire $299 million of our 7.125% Notes due March 15, 2020, $74 million of our 5.95% Notes due March 15, 2022, $62 million of our 7.75% Notes due August 1, 2029, and $100 million of our 6.5% Notes due August 15, 2032. In connection with these early retirements, we incurred a loss on debt extinguishment of $107 million, which was recorded as interest expense.

On March 28, 2013, we entered into a credit agreement (the “Credit Agreement”) with a bank group, with an aggregate commitment of $1.25 billion and a maturity date of March 28, 2018. On May 29, 2015 and August 28, 2015, we amended the Credit Agreement with the bank group (the "Amended Credit Agreement"). The Amended Credit Agreement reduces the aggregate commitment to $750 million and extends the maturity date to May 29, 2020.  Under the Amended Credit Agreement, at our request and subject to certain conditions, we can increase the aggregate commitment up to an additional $375 million with the current bank group or new lenders.

The Amended Credit Agreement provides for an unsecured revolving credit facility available to us and one of our foreign subsidiaries, in U.S. dollars, European euros and certain other currencies. Borrowings under the revolver denominated in euros are limited to $500 million, equivalent. We can also borrow swingline loans up to $75 million and obtain letters of credit of up to $100 million; outstanding letters of credit under the Amended Credit Agreement reduce our borrowing capacity. At June 30, 2018, we had no outstanding standby letters of credit under the Amended Credit Agreement.

Revolving credit loans bear interest under the Amended Credit Agreement, at our option, at (A) a rate per annum equal to the greater of (i) the prime rate, (ii) the Federal Funds effective rate plus 0.50% and (iii) LIBOR plus 1.0% (the "Alternative Base Rate"); plus an applicable margin based upon our then-applicable corporate credit ratings; or (B) LIBOR plus an applicable margin based upon our then-applicable corporate credit ratings. The foreign currency revolving credit loans bear interest at a rate equal to LIBOR plus an applicable margin based upon our then-applicable corporate credit ratings.

The Amended Credit Agreement contains financial covenants requiring us to maintain (A) a maximum net leverage ratio, as adjusted for certain items, of 4.0 to 1.0, and (B) a minimum interest coverage ratio, as adjusted for certain items, equal to or greater than 2.5 to 1.0.

I. DEBT (Concluded)

In order for us to borrow under the Amended Credit Agreement, there must not be any default in our covenants in the Amended Credit Agreement (i.e., in addition to the two financial covenants, principally limitations on subsidiary debt, negative pledge restrictions, legal compliance requirements and maintenance of properties and insurance) and our representations and warranties in the Amended Credit Agreement must be true in all material respects on the date of borrowing (i.e., principally no material adverse change or litigation likely to result in a material adverse change, since December 31, 2014, in each case, no material ERISA or environmental non-compliance, and no material tax deficiency). We were in compliance with all covenants and no borrowings were outstanding at June 30, 2018. 

Fair Value of Debt. The fair value of our short-term and long-term fixed-rate debt instruments is based principally upon modeled market prices for the same or similar issues, which are Level 1 inputs. The aggregate estimated market value was approximately $3.0 billion at June 30, 2018, which equaled the aggregate carrying value of short-term and long-term debt at that date. The aggregate estimated market value of short-term and long-term debt was approximately $3.3 billion, compared with the aggregate carrying value of $3.1 billion, at December 31, 2017.

J. STOCK-BASED COMPENSATION

Our 2014 Long Term Stock Incentive Plan provides for the issuance of stock-based incentives in various forms to our employees and non-employee Directors. At June 30, 2018, outstanding stock-based incentives were in the form of long-term stock awards, stock options, restricted stock units, phantom stock awards and stock appreciation rights.    

Pre-tax compensation expense for these stock-based incentives was as follows, in millions:

Long-Term Stock Awards. Long-term stock awards are granted to our key employees and non-employee Directors and do not cause net share dilution inasmuch as we continue the practice of repurchasing and retiring an equal number of shares in the open market. We granted 629,970 shares of long-term stock awards in the six-month period endedJune 30, 2018.

For the three-month and six-month periods endedJune 30, 2018 and 2017, we allocated dividends and undistributed earnings to the unvested restricted stock awards.

Additionally, 675,000 and 606,000 common shares for the three-month and six-month periods endedJune 30, 2018, respectively, and 397,000 and 310,000 common shares for the three-month and six-month periods endedJune 30, 2017, respectively, related to stock options were excluded from the computation of diluted income per common share due to their antidilutive effect.

In May 2017, our Board of Directors authorized the repurchase, for retirement, of up to $1.5 billion of shares of our common stock in open-market transactions or otherwise, replacing the previous Board of Directors authorization established in 2014. In the first six months of 2018, we repurchased and retired 6.7 million shares of our common stock (including 0.6 million shares to offset the dilutive impact of long-term stock awards granted in the first half of the year). At June 30, 2018, we had $1.0 billion remaining under the 2017 authorization.

On the basis of amounts paid (declared), cash dividends per common share were $0.105 ($0.105) and $0.210 ($0.210) for the three-month and six-month periods endedJune 30, 2018, respectively, and $0.100 ($0.100) and $0.200 ($0.200) for the three-month and six-month periods endedJune 30, 2017, respectively.

P. OTHER COMMITMENTS AND CONTINGENCIES

We are involved in claims and litigation, including class actions and regulatory proceedings, which arise in the ordinary course of our business. The types of matters may include, among others: competition, product liability, employment, warranty, advertising, contract, personal injury, environmental, intellectual property, and insurance coverage. We believe we have adequate defenses in these matters and that the likelihood that the outcome of these matters would have a material adverse effect on us is remote. However, there is no assurance that we will prevail in these matters, and we could, in the future, incur judgments, enter into settlements of claims or revise our expectations regarding the outcome of these matters, which could materially impact our results of operations.

Q. INCOME TAXES

Our effective tax rate was 28 percent and 25 percent for the three-month and six-month periods ended June 30, 2018, respectively. Our tax rate was higher than our 2018 statutory tax rate of 21 percent for these periods due primarily to an increase from state and local taxes, net of U.S. Federal tax benefit, of four percent and an increase from U.S. and foreign taxes on foreign earnings of three percent. The higher tax rate for the six-month period ended June 30, 2018 was partially offset by a decrease from an income tax benefit on stock-based compensation of three percent.

Our effective tax rate was 33 percent and 31 percent for the three-month and six-month periods ended June 30, 2017, respectively. Our tax rate was lower than our 2017 statutory tax rate of 35 percent for these periods due primarily to a decrease from an income tax benefit on stock-based compensation of four percent and a decrease from lower foreign taxes on foreign earnings of one percent and two percent, respectively. These decreases were partially offset by an increase from state and local taxes, net of U.S. Federal tax benefit, of three percent and two percent, respectively.

We report our financial results in accordance with generally accepted accounting principles ("GAAP") in the United States. However, we believe that certain non-GAAP performance measures and ratios used in managing the business may provide users of this financial information with additional meaningful comparisons between current results and results in prior periods. Non-GAAP performance measures and ratios should be viewed in addition to, and not as an alternative for, our reported results under GAAP.

The following discussion of consolidated results of operations and segment results refers to the three-month and six-month periods ended June 30, 2018 compared to the same periods of 2017.

NET SALES

Net sales increased 11 percent and 10 percent for the three-month and six-month periods ended June 30, 2018, respectively. Excluding acquisitions, divestitures and the favorable effect of currency translation, net sales increased six percent and five percent for the three-month and six-month periods ended June 30, 2018, respectively. The following table reconciles reported net sales to net sales, excluding acquisitions, divestitures and the effect of currency translation, in millions:

	Three Months Ended June 30,						Six Months Ended June 30,
	2018			2017			2018			2017

Net sales, excluding acquisitions, divestitures and the effect of currency translation	$	2,153		$	2,036		$	3,986		$	3,790

North American net sales increased 12 percent and 10 percent for the three-month and six-month periods ended June 30, 2018, respectively. Net sales were positively impacted by increased sales volume of plumbing products, cabinets, paints and other coating products and builders' hardware, which, in aggregate, increased sales by five percent for the three-month period ended June 30, 2018. These same drivers, as well as increased sales volume of windows, in aggregate, increased sales by four percent for the six-month period ended June 30, 2018. Net selling price increases of paints and other coating products, cabinets and windows also increased sales by two percent and one percent for the three-month and six-month periods ended June 30, 2018, respectively. The acquisitions of Kichler and Mercury Plastics, Inc. ("Mercury Plastics") increased sales by seven percent and five percent for the three-month and six-month periods ended June 30, 2018, respectively. Such increases were partially offset by the divestiture of Arrow Fastener Co., LLC ("Arrow") which decreased sales by one percent for both the three-month and six-month periods ended June 30, 2018.

International net sales increased seven percent and nine percent for the three-month and six-month periods ended June 30, 2018, respectively, due primarily to a weaker U.S. dollar. In local currencies (including sales in currencies outside their respective functional currencies), net sales were flat and decreased one percent for the three-month and six-month periods ended June 30, 2018, respectively. Net sales were positively impacted by increased sales volume of plumbing products and net selling price increases of plumbing products and windows which, in aggregate, increased sales by five percent for both the three-month and six-month periods ended June 30, 2018. Such increases were offset by the divestiture of Moores Furniture Group Limited ("Moores") in the fourth quarter of 2017, which decreased sales by three percent for both the three-month and six-month periods ended June 30, 2018. Decreased sales volume of windows and, for the six-month period only, unfavorable sales mix of plumbing products also decreased sales, in aggregate, by one percent and two percent for the three-month and six-month periods ended June 30, 2018, respectively.

Net sales in the Plumbing Products segment increased nine percent and 10 percent for the three-month and six-month periods ended June 30, 2018, respectively, due to increased sales volume of both North American and International operations, which increased sales by six percent for both the three-month and six-month periods ended June 30, 2018. Foreign currency translation further increased net sales by three percent and four percent for the three-month and six-month periods ended June 30, 2018, respectively, primarily due to the weaker U.S. dollar. The acquisition

25

of Mercury Plastics increased sales by one percent for both the three-month and six-month periods ended June 30, 2018. Such increases were partially offset by unfavorable sales mix of North American operations and, for the six-month period only, International operations, which, in aggregate, decreased sales by one percent for both the three-month and six-month periods ended June 30, 2018.

Net sales in the Decorative Architectural Products segment increased 22 percent and 17 percent for the three-month and six-month periods ended June 30, 2018, respectively, due primarily to the acquisition of Kichler in March 2018, which increased sales by 16 percent and 12 percent for the three-month and six-month periods ended June 30, 2018, respectively. Net sales also increased due to increased sales volume of paints and other coatings products and builders' hardware, and net selling price increases of paints and other coating products.

Net sales in the Cabinetry Products segment increased seven percent and one percent for the three-month and six-month periods ended June 30, 2018, due to increased sales volume which increased sales by nine percent and three percent for the three-month and six-month periods ended June 30, 2018, respectively. Net selling price increases and, for the six-month period only, favorable sales mix, further increased sales, in aggregate, by three percent for both the three-month and six-month periods ended June 30, 2018. These increases were partially offset by the divestiture of Moores, which decreased sales by five percent for both the three-month and six-month periods ended June 30, 2018.

Net sales in the Windows and Other Specialty Products segment decreased seven percent and two percent for the three-month and six-month periods ended June 30, 2018, respectively, due primarily to the divestiture of Arrow in the second quarter of 2017 which decreased sales by eight percent for both the three-month and six-month periods ended June 30, 2018. Decreased sales volume of international windows also decreased sales by two percent and three percent for the three-month and six-month periods ended June 30, 2018, respectively. Such decreases were partially offset by increased sales volume and favorable sales mix of North American windows, which, in aggregate, increased sales by five percent for the six-month period ended June 30, 2018. Net selling prices increases also increased sales by two percent for both the three-month and six-month periods ended June 30, 2018. Foreign currency translation also increased sales by one percent and two percent for the three-month and six-month periods ended June 30, 2018, respectively.

OPERATING MARGINS

Our gross profit margins were 32.7 percent and 32.5 percent for the three-month and six-month periods ended June 30, 2018, respectively, compared with 36.1 percent and 35.1 percent for the comparable periods of 2017. Gross profit margins were negatively affected by the partial recognition of the inventory step up adjustment established as part of the acquisition of Kichler, an unfavorable relationship between net selling prices and commodity costs, unfavorable sales mix, an increase in strategic growth initiatives, and an increase in other expenses, such as logistics costs. These negative impacts were partially offset by increased sales volume.

Selling, general and administrative expenses, as a percentage of sales, were 17.1 percent and 18.2 percent for the three-month and six-month periods ended June 30, 2018, respectively, compared to 18.1 percent and 18.8 percent. The decrease in selling, general and administrative expenses, as a percentage of sales, was driven by improved leverage of fixed expenses, due primarily to increased sales volume.

Operating margins in the Plumbing Products segment for the three-month and six-month periods ended June 30, 2018 were negatively impacted by an unfavorable relationship between net selling prices and commodity costs, unfavorable sales mix, higher depreciation expense, and an increase in other expenses, such as headcount and salaries, logistics costs and Enterprise Resource Planning system costs. These negative impacts were partially offset by increased sales volume and the benefits associated with cost savings initiatives.

Operating margins in the Decorative Architectural Products segment for the three-month and six-month periods ended June 30, 2018 were negatively impacted by the partial recognition of the inventory step up adjustment established as part of the acquisition of Kichler and increased depreciation and amortization expense. For the six-month period only, operating margin was also negatively impacted by investments in strategic growth initiatives as well as other expenses, including legal costs. These negative impacts were partially offset by increased sales volume and benefits associated with cost savings initiatives of paints and other coating products and builders' hardware.

26

Operating margins in the Cabinetry Products segment for the three-month and six-month periods ended June 30, 2018 were negatively impacted by unfavorable sales mix, program launch and display expenses, and an increase in other expenses, such as logistics costs. These negative impacts were partially offset by increased sales volume, the divestiture of Moores, and benefits associated with cost savings initiatives.

Operating margins in the Windows and Other Specialty Products segment for the three-month and six-month periods ended June 30, 2018 were negatively impacted by an increase in other expenses, such as warranty and related service costs and higher labor costs, which have more than offset benefits associated with cost savings initiatives. The divestiture of Arrow in the second quarter of 2017 also negatively impacted operating margins. These negative impacts were partially offset by a favorable relationship between net selling price and commodity costs.

OTHER INCOME (EXPENSE), NET

Interest expense for the three-month and six-month periods ended June 30, 2018 was $38 million and $79 million, respectively, compared to $153 million and $196 million for the three-month and six-month periods ended June 30, 2017. Interest expense decreased due to $107 million of debt extinguishment costs in 2017, which was recorded as additional interest expense, combined with refinancing certain debt at more favorable interest rates and the retirement of all of our all of our $114 million, 6.625% Notes in the second quarter of 2018.

Other, net, for the three-month and six-month periods ended June 30, 2018 included $5 million and $9 million, respectively, of net periodic pension and post-retirement benefit cost, $5 million and $6 million, respectively, of foreign currency transaction losses, and $2 million of earnings related to equity method investments. Other, net, for the three-month and six-month periods ended June 30, 2017 included $49 million of gains related to the sale of Arrow, $8 million and $15 million, respectively, of net periodic pension and post-retirement benefit cost, $1 millionand$2 million, respectively,of distributions from private equity funds, and$1 million of earnings related to equity method investments. The three-month period ended June 30, 2017 also included$1 millionof foreign currency transaction losses.

INCOME PER COMMON SHARE — ATTRIBUTABLE TO MASCO CORPORATION

Income for the three-month and six-month periods ended June 30, 2018 was $211 million and $360 million, respectively, compared with $163 million and $301 million, respectively, for the comparable periods of 2017. Diluted income per common share for the three-month and six-month periods ended June 30, 2018 was $.68 and $1.15, respectively, per common share, compared with $.51 and $.93, respectively, per common share for the comparable periods of 2017.

Our effective tax rate of 28 percent for the three-month period ended June 30, 2018 was higher than our normalized tax rate of 26 percent due primarily to $3 million of income tax expense resulting from enacted state and local tax law changes. Our effective tax rate of 25 percent for the six-month period ended June 30, 2018 was lower than our normalized tax rate of 26 percent due primarily to $10 million of income tax benefit on stock-based compensation, partially offset by $3 million of income tax expense resulting from enacted state and local tax law changes.

Our effective tax rate of 33 percent and 31 percent for the three-month and six-month periods ended June 30, 2017, respectively, was lower than our normalized tax rate of 34 percent due primarily to an income tax benefit on stock-based compensation of $10 million and $17 million, respectively, and, for the six-month period only, an income tax benefit on uncertain tax positions resulting from the expiration of applicable statutes of limitation of $3 million.

OTHER FINANCIAL INFORMATION

Our current ratio was 1.7 to 1 and 2.0 to 1 at June 30, 2018 and December 31, 2017, respectively. The decrease in our current ratio is due primarily to the cash on hand we paid for our acquisition of Kichler, partially offset by the acquired working capital.

For the six-month period endedJune 30, 2018, net cash provided by operating activities was $293 million.

For the six-month period endedJune 30, 2018, net cash used for financing activities was $567 million, primarily due to $265 million for the repurchase and retirement of Company common stock (including 0.6 million shares repurchased to offset the dilutive impact of long-term stock awards granted in 2018), $114 million for the retirement of

27

our 6.625% of Notes due April 15, 2018, $89 million for dividends paid to noncontrolling interests, $65 million for the payment of cash dividends, and $33 million for employee withholding taxes paid on stock-based compensation.

For the six-month period endedJune 30, 2018, net cash used for investing activities was $544 million, primarily due to $548 million for the acquisition of Kichler, net of cash acquired, and $103 million used for capital expenditures, offset by $108 million in proceeds from the disposition of short-term bank deposits.

Our cash, cash investments and short-term bank deposits were $384 million and $1.3 billion at June 30, 2018 and December 31, 2017, respectively. Our cash and cash investments consist of overnight interest bearing money market demand accounts, time deposit accounts, and money market mutual funds containing government securities and treasury obligations. Our short-term bank deposits consist of time deposits with maturities of 12 months or less.

Of the $384 million and $1.3 billion of cash, cash investments and short-term bank deposits held at June 30, 2018 and December 31, 2017, $197 million and $759 million, respectively, was held in our foreign subsidiaries. If these funds were needed for our operations in the U.S., their repatriation into the U.S. would not result in significant additional U.S. income tax or foreign withholding tax, as we have recorded such taxes on substantially all undistributed foreign earnings, except for those that are legally restricted.

On March 28, 2013, we entered into a credit agreement (the "Credit Agreement") with a bank group, with an aggregate commitment of $1.25 billion and a maturity date of March 28, 2018. On May 29, 2015 and August 28, 2015, we amended the Credit Agreement with the bank group (the "Amended Credit Agreement"). The Amended Credit Agreement reduces the aggregate commitment to $750 million and extended the maturity date to May 29, 2020. Under the Amended Credit Agreement, at our request and subject to certain conditions, we can increase the aggregate commitment up to an additional $375 million with the current bank group or new lenders. See Note I to the condensed consolidated financial statements.

The Amended Credit Agreement contains financial covenants requiring us to maintain (A) a maximum net leverage ratio, as adjusted for certain items, of 4.0 to 1.0, and (B) a minimum interest coverage ratio, as adjusted for certain items, equal to or greater than 2.5 to 1.0. All amounts borrowed during the quarter to temporarily fund our working capital needs were repaid in the quarter.  We were in compliance with all covenants and no borrowings were outstanding under our Amended Credit Agreement at June 30, 2018.

We believe that our present cash balance, cash flows from operations, and the ability to utilize our Amended Credit Agreement are sufficient to fund our near-term working capital and other investment needs. We believe that our longer-term working capital and other general corporate requirements will be satisfied through cash flows from operations and, to the extent necessary, from bank borrowings and future financial market activities.

OUTLOOK FOR THE COMPANY

We continue to successfully execute our long-term growth strategies by leveraging our strong brand portfolio, industry-leading positions and Masco Operating System, our methodology to drive growth and productivity. We believe the fundamentals of our industry remain strong and support our long-term growth. We believe that our strong financial position and cash flow generation, together with our current strategy of investing in our industry-leading branded building products, our continued focus on innovation and our commitment to operational excellence, the active management of our portfolio and disciplined capital allocation will allow us to drive long-term growth and create value for our shareholders.

The Company’s principal executive officer and principal financial officer have concluded, based on an evaluation of the Company’s disclosure controls and procedures (as defined in the Securities Exchange Act of 1934 Rules 13a-15(e) or 15d-15(e)) as required by paragraph (b) of Exchange Act Rules 13a-15 or 15d-15 that, as of June 30, 2018, the Company's disclosure controls and procedures were effective.

b.     Changes in Internal Control over Financial Reporting.

During the second quarter of 2018, we implemented a new Enterprise Resource Planning ("ERP") system at Delta Faucet Company ("Delta"). The system implementation was designed, in part, to enhance the overall system of internal control over financial reporting through further automation and to improve business processes, and was not in response to any identified deficiency or weakness in the Company's internal control over financial reporting. This system implementation was significant in scale and complexity and has resulted in modification to certain internal controls at Delta. All controls are currently operating as intended.

Accounting Policies [Abstract]

Accounting Policies

ACCOUNTING POLICIES

In our opinion, the accompanying unaudited condensed consolidated financial statements contain all adjustments, of a normal recurring nature, necessary to fairly state our financial position at June 30, 2018, our results of operations and comprehensive income (loss) for the three-month and six-month periods ended June 30, 2018 and 2017, and cash flows and changes in shareholders' equity for the six-month periods ended June 30, 2018 and 2017. The condensed consolidated balance sheet at December 31, 2017 was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

Reclassification. Certain prior year amounts have been reclassified to conform to the 2018 presentation in the condensed consolidated financial statements. 

Income Tax Effects within Accumulated Other Comprehensive Income (Loss). The accounting guidance for income taxes requires us to allocate our provision for income taxes between continuing operations and other categories of earnings, such as other comprehensive income (loss). Subsequent adjustments to deferred taxes originally recorded to other comprehensive income (loss) may reverse in a different category of earnings, such as continuing operations, resulting in a disproportionate tax effect within accumulated other comprehensive income (loss). Generally, a disproportionate tax effect will be eliminated and recognized in income tax expense (benefit) when the circumstances upon which it is premised cease to exist.

The disproportionate tax effect related to various defined-benefit pension plans will be eliminated from accumulated other comprehensive income (loss) at the termination of the related pension plans. The disproportionate tax effect relating to our interest rate swap hedge, which was terminated in 2012, will be eliminated from accumulated other comprehensive income (loss) upon the maturity of the related debt in March 2022.

Recently Adopted Accounting Pronouncements. In May 2014, the Financial Accounting Standards Board ("FASB") issued a new standard for revenue recognition, Accounting Standards Codification ("ASC") 606. The purpose of ASC 606 is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability across industries. We adopted ASC 606 on January 1, 2018, under the full retrospective method of adoption. As a result of this adoption, net sales increased by $9 million and $10 million for the three-month and six-month periods ended June 30, 2017, respectively, and operating profit (and income before income taxes) increased by $7 million and $4 million for the three-month and six-month periods ended June 30, 2017, respectively, from what was previously reported. For full year 2017 and 2016, net sales decreased by $2 million and increased by $4 million, respectively, and operating profit (and income before income taxes) decreased by $1 million and increased by $2 million, respectively, from what was previously reported. We additionally have recasted our previously reported segment operating results at the end of this section.

In January 2016, the FASB issued ASU 2016-01, "Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities," which primarily affects the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. We adopted ASU 2016-01 on January 1, 2018. The adoption of this standard did not have a material impact on our financial position or results of operations.

In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Asset Transfers of Assets Other than Inventory," which no longer allows the tax effects of intra-entity asset transfers (intercompany sales) of assets other than inventory to be deferred until the transferred asset is sold to a third party or otherwise recovered through use. The new standard requires the tax expense from the sale of the asset in the seller's tax jurisdiction and the corresponding basis differences in the buyer's jurisdiction to be recognized when the transfer occurs even though the pre-tax effects of the transaction are eliminated in consolidation. We adopted ASU 2016-16 on January 1, 2018. The adoption of this standard did not have a material impact on our financial position or results of operations.

A. ACCOUNTING POLICIES (Continued)

In March 2017, the FASB issued ASU 2017-07, "Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which modifies the presentation of net periodic pension and post-retirement benefit cost ("net benefit cost") in the income statement and the components eligible for capitalization as assets. ASU 2017-07 requires retrospective application for certain aspects of the standard. We adopted ASU 2017-07 on January 1, 2018. As a result of the adoption, we reclassified $8 million and $15 million of net benefit cost from operating profit to other income (expense), net, within our results of operations for the three-month and six-month periods ended June 30, 2017, respectively. For full year 2017 and 2016, we reclassified $26 million and $32 million, respectively, of net benefit cost from operating profit to other income (expense), net, within our results of operations. We additionally have recasted our previously reported segment operating results at the end of this section. The adoption of the standard did not impact income before income taxes.

In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting," which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. We adopted ASU 2017-09 on January 1, 2018. The adoption of this standard did not impact our financial position or results of operations; however, modification accounting is now required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions.

In February 2018, the FASB issued ASU 2018-02, "Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which permits a company to reclassify from accumulated other comprehensive income (loss) to retained earnings the disproportionate tax effects resulting from the Tax Cuts and Jobs Act of 2017 (“2017 Act”). We early adopted ASU 2018-02 on March 31, 2018. As a result of the adoption, in the first quarter of 2018 we decreased accumulated other comprehensive income (loss) and increased retained earnings (deficit) by the $59 million disproportionate tax effect caused by the 2017 Act.

Impact of Adoption of ASC 606 and ASU 2017-07. The recasted impact of the adoptions of ASC 606 and ASU 2017-07 to our previously reported operating results and basic and diluted income per share was as follows, in millions (except per common share data):

A. ACCOUNTING POLICIES (Concluded)

Recently Issued Accounting Pronouncements. In February 2016, the FASB issued a new standard for leases, ASC 842, which changes the accounting model for identifying and accounting for leases. ASC 842 is effective for us for annual periods beginning January 1, 2019. We expect this standard to increase our total assets and total liabilities; however, we are currently evaluating the magnitude of the impact. We do not expect the standard to have a material impact on our results of operations. In preparation for the adoption of the standard, we have procured a third-party software to track and manage our leases and have trained our business units on the new standard and the use of the software.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," which modifies the methodology for recognizing loss impairments on certain types of financial instruments, including receivables. The new methodology requires an entity to estimate the credit losses expected over the life of an exposure. Additionally, ASU 2016-13 amends the current available-for-sale security other-than-temporary impairment model for debt securities. ASU 2016-13 is effective for us for annual periods beginning January 1, 2020. We are currently evaluating the impact the adoption of this new standard will have on our financial position and results of operations.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities," which improves and simplifies accounting rules around hedge accounting and better portrays the economic results of an entity's risk management activities in its financial statements. ASU 2017-12 is effective for us for annual periods beginning January 1, 2019. We are currently evaluating the impact the adoption of this new standard will have on our financial position and results of operations.

In June 2018, the FASB issued ASU 2018-07, "Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting," which modifies the accounting for share-based payment awards issued to nonemployees to largely align it with the accounting for share-based payment awards issued to employees. ASU 2018-07 is effective for us for annual periods beginning January 1, 2019. We do not expect the adoption of the standard will impact our financial position or results of operations.

Acquisitions

ACQUISITIONS

On March 9, 2018, we acquired substantially all of the net assets of The L.D. Kichler Co. ("Kichler"), a leader in decorative residential and light commercial lighting products, ceiling fans and LED lighting systems. This business expands our product offerings to our customers. The results of this acquisition for the period from the acquisition date are included in the condensed consolidated financial statements and are reported in the Decorative Architectural Products segment. For the three-month and six-month periods endedJune 30, 2018, we recorded $108 million and $135 million, respectively, of net sales as a result of this acquisition. The purchase price, net of $2 million cash acquired, consisted of $548 million paid at closing with cash on hand.

During the three-month period ended June 30, 2018, we revised the allocation of the purchase price to identifiable assets and liabilities based on analysis of information as of the acquisition date that has been made available through June 30, 2018.  Receipt of additional information to complete such analysis and finalization of the valuation is still in process, and, as a result, the allocation will continue to be updated through the measurement period, if necessary.  The preliminary allocation of the fair value of the acquisition of Kichler is summarized in the following table, in millions.

	Initial			Revised
Receivables	$	101		$	101
Inventories	173			169
Other current assets	5			5
Property and equipment	33			33
Goodwill	46			55

Accounts payable	(24		)	(24		)
Accrued liabilities	(25		)	(27		)
Other liabilities	(4		)	(4		)
Total	$	548		$	548

The goodwill acquired, which is generally tax deductible, is related primarily to the operational and financial synergies we expect to derive from combining Kichler's operations into our business, as well as the assembled workforce. The other intangible assets acquired consist of $59 million of indefinite-lived intangible assets, which is related to trademarks, and $181 million of definite-lived intangible assets. The definite-lived intangible assets consist of $145 million related to customer relationships, which is being amortized on a straight-line basis over 20 years, and $36 million of other definite-lived intangible assets, which is being amortized over a weighted-average amortization period of 3 years.

Revenues [Abstract]

Revenue

REVENUE

We recognize revenue as control of our products is transferred to our customers, which is generally at the time of shipment or upon delivery based on the contractual terms with our customers, or when services are completed. Control over certain of our custom-made window products transfers to our customers as production is completed, and revenue is recognized over the production period for these products, as our products do not have an alternative use and we have an enforceable right to payment during the production period. The production period of our custom-made window products generally does not lapse days, and for these products we currently recognize revenue based on the output of production, which is a faithful depiction of the transfer of these products to our customers. Our customers' payment terms generally range from 30 to 65 days of fulfilling our performance obligations and recognizing revenue.

We consider shipping and handling activities performed by us as activities to fulfill the sales of our products. Amounts billed for shipping and handling are included in net sales, while costs incurred for shipping and handling are included in cost of sales. We capitalize incremental costs of obtaining a contract and expense the costs on a straight-line basis over the contractual period if the cost is recoverable, the cost would not have been incurred without the contract and the term of the contract is greater than one year; otherwise, we expense the amounts as incurred. We do not adjust the promised amount of consideration for the effects of a financing component if the period between when we transfer our products or services and when our customers pay for our products or services is expected to be one year or less.

Our revenues are derived primarily from sales to customers in North America and Internationally, principally Europe. Net sales from these geographic markets, by segment, were as follows, in millions:

We provide customer programs and incentive offerings, including special pricing and co-operative advertising arrangements, promotions and other volume-based incentives. These customer programs and incentives are considered variable consideration. We include in revenue variable consideration only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the variable consideration is resolved. This determination is made based upon known customer program and incentive offerings at the time of sale, and expected sales volume forecasts as it relates to our volume-based incentives. This determination is updated each reporting period. We recognized$6 millionand$3 million for the three-month and six-month periods endedJune 30, 2018, respectively, and $8 million and $7 million for the three-month and six-month periods endedJune 30, 2017, respectively, of revenue related to performance obligations settled in previous periods.

Certain product sales include a right of return. We estimate future product returns at the time of sale based on historical experience and record a corresponding refund liability. We additionally record an asset, based on historical experience, for the amount of product we expect to return to inventory as a result of the return, which is recorded in prepaid expenses and other in the condensed consolidated balance sheets.

We record contract assets for items for which we have satisfied our performance obligation but our receipt of payment is contingent upon delivery or other circumstances other than the passage of time. Our contract assets are recorded in prepaid expenses and other in our condensed consolidated balance sheets. Our contract assets generally

become unconditional and are reclassified to receivables in the quarter subsequent to each balance sheet date. Our contract asset balance was $14 million and $11 million at June 30, 2018 and December 31, 2017, respectively.

We record contract liabilities primarily for deferred revenue. Our contract liabilities are recorded in accrued liabilities in our condensed consolidated balance sheets. Our contract liabilities are generally recognized to net sales in the immediately subsequent reporting period. Our contract liability balance was $13 million and $32 million at June 30, 2018 and December 31, 2017, respectively.

Derivative Instruments and Hedging Activities

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

We are exposed to global market risk as part of our normal, daily business activities. To manage these risks, we enter into various derivative contracts. These contracts may include interest rate swap agreements and foreign currency contracts. We review our hedging program, derivative positions and overall risk management on a regular basis.

Interest Rate Swap Agreements. In 2012, in connection with the issuance of $400 million of debt, we terminated the interest rate swap hedge relationships that we had entered into in 2011. These interest rate swaps were designated as cash flow hedges and effectively fixed interest rates on the forecasted debt issuance to variable rates based on 3-month LIBOR. Upon termination, the ineffective portion of the cash flow hedges of an approximate $2 million loss was recognized in our consolidated statement of operations in other, net, within other income (expense), net. The remaining loss of approximately $23 million from the termination of these swaps is being amortized as an increase to interest expense over the remaining term of the debt, through March 2022. At June 30, 2018, the balance remaining in accumulated other comprehensive loss was $7 million (pre-tax).

G. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES (Concluded)

Foreign Currency Contracts. Our net cash inflows and outflows exposed to the risk of changes in foreign currency exchange rates arise from the sale of products in countries other than the manufacturing source, foreign currency denominated supplier payments, debt and other payables, and investments in subsidiaries. To mitigate this risk, we, including certain of our European operations, enter into foreign currency forward contracts and foreign currency exchange contracts.

Gains (losses) related to foreign currency forward and exchange contracts are recorded in our condensed consolidated statement of operations in other income (expense), net. In the event that the counterparties fail to meet the terms of the foreign currency forward or exchange contracts, our exposure is limited to the aggregate foreign currency rate differential with such institutions.

The pre-tax gains (losses) included in our condensed consolidated statements of operations were as follows, in millions:

DEBT

On April 16, 2018, we repaid and retired all of our $114 million, 6.625% Notes on the scheduled repayment date.    

On June 21, 2017, we issued $300 million of 3.5% Notes due November 15, 2027 and $300 million of 4.5% Notes due May 15, 2047. We received proceeds of $599 million, net of discount, for the issuance of these Notes. The Notes are senior indebtedness and are redeemable at our option at the applicable redemption price. On June 27, 2017, proceeds from the debt issuances, together with cash on hand, were used to repay and early retire $299 million of our 7.125% Notes due March 15, 2020, $74 million of our 5.95% Notes due March 15, 2022, $62 million of our 7.75% Notes due August 1, 2029, and $100 million of our 6.5% Notes due August 15, 2032. In connection with these early retirements, we incurred a loss on debt extinguishment of $107 million, which was recorded as interest expense.

On March 28, 2013, we entered into a credit agreement (the “Credit Agreement”) with a bank group, with an aggregate commitment of $1.25 billion and a maturity date of March 28, 2018. On May 29, 2015 and August 28, 2015, we amended the Credit Agreement with the bank group (the "Amended Credit Agreement"). The Amended Credit Agreement reduces the aggregate commitment to $750 million and extends the maturity date to May 29, 2020.  Under the Amended Credit Agreement, at our request and subject to certain conditions, we can increase the aggregate commitment up to an additional $375 million with the current bank group or new lenders.

The Amended Credit Agreement provides for an unsecured revolving credit facility available to us and one of our foreign subsidiaries, in U.S. dollars, European euros and certain other currencies. Borrowings under the revolver denominated in euros are limited to $500 million, equivalent. We can also borrow swingline loans up to $75 million and obtain letters of credit of up to $100 million; outstanding letters of credit under the Amended Credit Agreement reduce our borrowing capacity. At June 30, 2018, we had no outstanding standby letters of credit under the Amended Credit Agreement.

Revolving credit loans bear interest under the Amended Credit Agreement, at our option, at (A) a rate per annum equal to the greater of (i) the prime rate, (ii) the Federal Funds effective rate plus 0.50% and (iii) LIBOR plus 1.0% (the "Alternative Base Rate"); plus an applicable margin based upon our then-applicable corporate credit ratings; or (B) LIBOR plus an applicable margin based upon our then-applicable corporate credit ratings. The foreign currency revolving credit loans bear interest at a rate equal to LIBOR plus an applicable margin based upon our then-applicable corporate credit ratings.

The Amended Credit Agreement contains financial covenants requiring us to maintain (A) a maximum net leverage ratio, as adjusted for certain items, of 4.0 to 1.0, and (B) a minimum interest coverage ratio, as adjusted for certain items, equal to or greater than 2.5 to 1.0.

I. DEBT (Concluded)

In order for us to borrow under the Amended Credit Agreement, there must not be any default in our covenants in the Amended Credit Agreement (i.e., in addition to the two financial covenants, principally limitations on subsidiary debt, negative pledge restrictions, legal compliance requirements and maintenance of properties and insurance) and our representations and warranties in the Amended Credit Agreement must be true in all material respects on the date of borrowing (i.e., principally no material adverse change or litigation likely to result in a material adverse change, since December 31, 2014, in each case, no material ERISA or environmental non-compliance, and no material tax deficiency). We were in compliance with all covenants and no borrowings were outstanding at June 30, 2018. 

Fair Value of Debt. The fair value of our short-term and long-term fixed-rate debt instruments is based principally upon modeled market prices for the same or similar issues, which are Level 1 inputs. The aggregate estimated market value was approximately $3.0 billion at June 30, 2018, which equaled the aggregate carrying value of short-term and long-term debt at that date. The aggregate estimated market value of short-term and long-term debt was approximately $3.3 billion, compared with the aggregate carrying value of $3.1 billion, at December 31, 2017.

Stock-Based Compensation

STOCK-BASED COMPENSATION

Our 2014 Long Term Stock Incentive Plan provides for the issuance of stock-based incentives in various forms to our employees and non-employee Directors. At June 30, 2018, outstanding stock-based incentives were in the form of long-term stock awards, stock options, restricted stock units, phantom stock awards and stock appreciation rights.    

Pre-tax compensation expense for these stock-based incentives was as follows, in millions: 

	Three Months Ended June 30,					Six Months Ended June 30,

Phantom stock awards and stock appreciation rights	(1		)	3		(1		)	5
Total	$	8		$	12	$	15		$	21

Long-Term Stock Awards. Long-term stock awards are granted to our key employees and non-employee Directors and do not cause net share dilution inasmuch as we continue the practice of repurchasing and retiring an equal number of shares in the open market. We granted 629,970 shares of long-term stock awards in the six-month period endedJune 30, 2018.

J. STOCK-BASED COMPENSATION (Continued)

Our long-term stock award activity was as follows, shares in millions:

Weighted average grant date fair value	$	30	$	24

There was $56 million of total unrecognized compensation expense related to unvested stock awards at bothJune 30, 2018 and 2017; such awards had a weighted average remaining vesting period of three years at both June 30,2018 and 2017.

The total market value (at the vesting date) of stock award shares which vested during the six-month periods endedJune 30, 2018 and 2017 was $54 million and $41 million, respectively.

Stock Options. Stock options are granted to certain key employees. The exercise price equals the market price of our common stock at the grant date. These options generally become exercisable (vest ratably) over five years beginning on the first anniversary from the date of grant and expire no later than 10 years after the grant date.

J. STOCK-BASED COMPENSATION (Continued)

We granted 385,220 shares of stock options in the six-month period endedJune 30, 2018 with a grant date weighted-average exercise price of approximately $42 per share. In the six-month period endedJune 30,2018, 68,927 shares of stock options were forfeited (including options that expired unexercised).

Our stock option activity was as follows, shares in millions:

Weighted average remaining option term (in years)		4		3

(A) Aggregate intrinsic value is calculated using our stock price at each respective date, less the exercise price (grant date price), multiplied by the number of shares.

At June 30, 2018 and 2017, there was $10 million and $9 million, respectively, of unrecognized compensation expense (using the Black-Scholes option pricing model at the grant date) related to unvested stock options; such options had a weighted average remaining vesting period of three years at both June 30, 2018 and 2017.

J. STOCK-BASED COMPENSATION (Concluded)

The weighted average grant date fair value of option shares granted and the assumptions used to estimate those values using a Black-Scholes option pricing model were as follows: 

	Six Months Ended June 30,
	2018			2017
Weighted average grant date fair value	$	12.52		$	9.68
Risk-free interest rate	2.71		%	2.16		%
Dividend yield	1.00		%	1.19		%
Volatility factor	29.00		%	30.00		%
Expected option life	6 years			6 years

Restricted Stock Units. Under the Long Term Incentive Program, we granted restricted stock units to certain senior executives. These restricted stock units vest and share awards are issued at no cost to the employees, subject to our achievement of specified return on invested capital performance goals over a three-year period that have been established by our Organization and Compensation Committee for the performance period and the recipient's continued employment through the share award date. We granted 113,260 restricted stock units in the six-month period endedJune 30, 2018, with a grant date fair value of approximately $42 per share, and 124,780 restricted stock units in the six-month period endedJune 30, 2017, with a grant date fair value of approximately $34 per share. During the six-month period endedJune 30, 2018, 11,600 restricted stock units were forfeited.

For the three-month and six-month periods endedJune 30, 2018 and 2017, we allocated dividends and undistributed earnings to the unvested restricted stock awards.

Additionally, 675,000 and 606,000 common shares for the three-month and six-month periods endedJune 30, 2018, respectively, and 397,000 and 310,000 common shares for the three-month and six-month periods endedJune 30, 2017, respectively, related to stock options were excluded from the computation of diluted income per common share due to their antidilutive effect.

In May 2017, our Board of Directors authorized the repurchase, for retirement, of up to $1.5 billion of shares of our common stock in open-market transactions or otherwise, replacing the previous Board of Directors authorization established in 2014. In the first six months of 2018, we repurchased and retired 6.7 million shares of our common stock (including 0.6 million shares to offset the dilutive impact of long-term stock awards granted in the first half of the year). At June 30, 2018, we had $1.0 billion remaining under the 2017 authorization.

On the basis of amounts paid (declared), cash dividends per common share were $0.105 ($0.105) and $0.210 ($0.210) for the three-month and six-month periods endedJune 30, 2018, respectively, and $0.100 ($0.100) and $0.200 ($0.200) for the three-month and six-month periods endedJune 30, 2017, respectively.

We are involved in claims and litigation, including class actions and regulatory proceedings, which arise in the ordinary course of our business. The types of matters may include, among others: competition, product liability, employment, warranty, advertising, contract, personal injury, environmental, intellectual property, and insurance coverage. We believe we have adequate defenses in these matters and that the likelihood that the outcome of these matters would have a material adverse effect on us is remote. However, there is no assurance that we will prevail in these matters, and we could, in the future, incur judgments, enter into settlements of claims or revise our expectations regarding the outcome of these matters, which could materially impact our results of operations.

INCOME TAXES

Our effective tax rate was 28 percent and 25 percent for the three-month and six-month periods ended June 30, 2018, respectively. Our tax rate was higher than our 2018 statutory tax rate of 21 percent for these periods due primarily to an increase from state and local taxes, net of U.S. Federal tax benefit, of four percent and an increase from U.S. and foreign taxes on foreign earnings of three percent. The higher tax rate for the six-month period ended June 30, 2018 was partially offset by a decrease from an income tax benefit on stock-based compensation of three percent.

Our effective tax rate was 33 percent and 31 percent for the three-month and six-month periods ended June 30, 2017, respectively. Our tax rate was lower than our 2017 statutory tax rate of 35 percent for these periods due primarily to a decrease from an income tax benefit on stock-based compensation of four percent and a decrease from lower foreign taxes on foreign earnings of one percent and two percent, respectively. These decreases were partially offset by an increase from state and local taxes, net of U.S. Federal tax benefit, of three percent and two percent, respectively.

Reclassification

Reclassification. Certain prior year amounts have been reclassified to conform to the 2018 presentation in the condensed consolidated financial statements. 

Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements

Recently Adopted Accounting Pronouncements. In May 2014, the Financial Accounting Standards Board ("FASB") issued a new standard for revenue recognition, Accounting Standards Codification ("ASC") 606. The purpose of ASC 606 is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability across industries. We adopted ASC 606 on January 1, 2018, under the full retrospective method of adoption. As a result of this adoption, net sales increased by $9 million and $10 million for the three-month and six-month periods ended June 30, 2017, respectively, and operating profit (and income before income taxes) increased by $7 million and $4 million for the three-month and six-month periods ended June 30, 2017, respectively, from what was previously reported. For full year 2017 and 2016, net sales decreased by $2 million and increased by $4 million, respectively, and operating profit (and income before income taxes) decreased by $1 million and increased by $2 million, respectively, from what was previously reported. We additionally have recasted our previously reported segment operating results at the end of this section.

In January 2016, the FASB issued ASU 2016-01, "Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities," which primarily affects the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. We adopted ASU 2016-01 on January 1, 2018. The adoption of this standard did not have a material impact on our financial position or results of operations.

In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Asset Transfers of Assets Other than Inventory," which no longer allows the tax effects of intra-entity asset transfers (intercompany sales) of assets other than inventory to be deferred until the transferred asset is sold to a third party or otherwise recovered through use. The new standard requires the tax expense from the sale of the asset in the seller's tax jurisdiction and the corresponding basis differences in the buyer's jurisdiction to be recognized when the transfer occurs even though the pre-tax effects of the transaction are eliminated in consolidation. We adopted ASU 2016-16 on January 1, 2018. The adoption of this standard did not have a material impact on our financial position or results of operations.

A. ACCOUNTING POLICIES (Continued)

In March 2017, the FASB issued ASU 2017-07, "Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which modifies the presentation of net periodic pension and post-retirement benefit cost ("net benefit cost") in the income statement and the components eligible for capitalization as assets. ASU 2017-07 requires retrospective application for certain aspects of the standard. We adopted ASU 2017-07 on January 1, 2018. As a result of the adoption, we reclassified $8 million and $15 million of net benefit cost from operating profit to other income (expense), net, within our results of operations for the three-month and six-month periods ended June 30, 2017, respectively. For full year 2017 and 2016, we reclassified $26 million and $32 million, respectively, of net benefit cost from operating profit to other income (expense), net, within our results of operations. We additionally have recasted our previously reported segment operating results at the end of this section. The adoption of the standard did not impact income before income taxes.

In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting," which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. We adopted ASU 2017-09 on January 1, 2018. The adoption of this standard did not impact our financial position or results of operations; however, modification accounting is now required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions.

In February 2018, the FASB issued ASU 2018-02, "Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which permits a company to reclassify from accumulated other comprehensive income (loss) to retained earnings the disproportionate tax effects resulting from the Tax Cuts and Jobs Act of 2017 (“2017 Act”). We early adopted ASU 2018-02 on March 31, 2018. As a result of the adoption, in the first quarter of 2018 we decreased accumulated other comprehensive income (loss) and increased retained earnings (deficit) by the $59 million disproportionate tax effect caused by the 2017 Act.

Impact of Adoption of ASC 606 and ASU 2017-07. The recasted impact of the adoptions of ASC 606 and ASU 2017-07 to our previously reported operating results and basic and diluted income per share was as follows, in millions (except per common share data):

A. ACCOUNTING POLICIES (Concluded)

Recently Issued Accounting Pronouncements. In February 2016, the FASB issued a new standard for leases, ASC 842, which changes the accounting model for identifying and accounting for leases. ASC 842 is effective for us for annual periods beginning January 1, 2019. We expect this standard to increase our total assets and total liabilities; however, we are currently evaluating the magnitude of the impact. We do not expect the standard to have a material impact on our results of operations. In preparation for the adoption of the standard, we have procured a third-party software to track and manage our leases and have trained our business units on the new standard and the use of the software.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," which modifies the methodology for recognizing loss impairments on certain types of financial instruments, including receivables. The new methodology requires an entity to estimate the credit losses expected over the life of an exposure. Additionally, ASU 2016-13 amends the current available-for-sale security other-than-temporary impairment model for debt securities. ASU 2016-13 is effective for us for annual periods beginning January 1, 2020. We are currently evaluating the impact the adoption of this new standard will have on our financial position and results of operations.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities," which improves and simplifies accounting rules around hedge accounting and better portrays the economic results of an entity's risk management activities in its financial statements. ASU 2017-12 is effective for us for annual periods beginning January 1, 2019. We are currently evaluating the impact the adoption of this new standard will have on our financial position and results of operations.

Revenue Recognition, Policy

We recognize revenue as control of our products is transferred to our customers, which is generally at the time of shipment or upon delivery based on the contractual terms with our customers, or when services are completed. Control over certain of our custom-made window products transfers to our customers as production is completed, and revenue is recognized over the production period for these products, as our products do not have an alternative use and we have an enforceable right to payment during the production period. The production period of our custom-made window products generally does not lapse days, and for these products we currently recognize revenue based on the output of production, which is a faithful depiction of the transfer of these products to our customers. Our customers' payment terms generally range from 30 to 65 days of fulfilling our performance obligations and recognizing revenue.

We consider shipping and handling activities performed by us as activities to fulfill the sales of our products. Amounts billed for shipping and handling are included in net sales, while costs incurred for shipping and handling are included in cost of sales. We capitalize incremental costs of obtaining a contract and expense the costs on a straight-line basis over the contractual period if the cost is recoverable, the cost would not have been incurred without the contract and the term of the contract is greater than one year; otherwise, we expense the amounts as incurred. We do not adjust the promised amount of consideration for the effects of a financing component if the period between when we transfer our products or services and when our customers pay for our products or services is expected to be one year or less.

Revenue Recognition, Revenue Reductions

We provide customer programs and incentive offerings, including special pricing and co-operative advertising arrangements, promotions and other volume-based incentives. These customer programs and incentives are considered variable consideration. We include in revenue variable consideration only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the variable consideration is resolved. This determination is made based upon known customer program and incentive offerings at the time of sale, and expected sales volume forecasts as it relates to our volume-based incentives. This determination is updated each reporting period. We recognized$6 millionand$3 million for the three-month and six-month periods endedJune 30, 2018, respectively, and $8 million and $7 million for the three-month and six-month periods endedJune 30, 2017, respectively, of revenue related to performance obligations settled in previous periods.

Revenue Recognition, Sales Returns

Certain product sales include a right of return. We estimate future product returns at the time of sale based on historical experience and record a corresponding refund liability. We additionally record an asset, based on historical experience, for the amount of product we expect to return to inventory as a result of the return, which is recorded in prepaid expenses and other in the condensed consolidated balance sheets.
