Item 8.01. Other Events.

Masco Corporation (the “Company”) is filing this Current Report on Form 8-K to reflect certain changes described below with respect to the financial information contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 (the “2012 Form 10-K”), which was filed with the Securities and Exchange Commission on February 15, 2013. Other than as described below, the information in this Form 8-K is not an amendment to or restatement of the 2012 Form 10-K.

As previously disclosed, the Company has determined that Tvilum, its Danish ready-to-assemble cabinet business (“Tvilum”) is no longer core to its long-term growth strategy and has embarked on a plan to dispose of this business. Tvilum has been accounted for as a discontinued operation which requires that prior period information be recast to remove Tvilum’s results of operations from the results of the Company’s continuing operations. Tvilum was reported as a discontinued operation in the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2013 filed with the Securities and Exchange Commission on May 1, 2013. Attached as exhibits to this Form 8-K are the following Form 10-K items recast to reflect the impact of Tvilum as a discontinued operation on the Company’s consolidated financial information:

• Part II, Item 6 – Selected Financial Data

• Part II, Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

• Part II, Item 8 – Financial Statements and Supplementary Data

• Schedule II – Valuation and Qualifying Accounts

Other than as described above, all other items in the 2012 Form 10-K remain unchanged, and this Form 8-K does not update Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the 2012 Form 10-K for any information, uncertainties, transactions, risks, events or trends occurring, or known to management. The information in this Form 8-K and the exhibits hereto should be read in conjunction with the 2012 Form 10-K.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The financial and business analysis below provides information which we believe is relevant to an assessment and understanding of our consolidated financial position, results of operations and cash flows. This financial and business analysis should be read in conjunction with the consolidated financial statements and related notes.

The following discussion and certain other sections of this Report contain statements reflecting our views about our future performance and constitute “forward-looking statements” under the Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as “anticipate,” “intend,” “plan,” “believe,” “estimate,” “expect,” “assume,” “seek,” “appear,” “may,” “should,” “will,” “forecast” and similar references to future periods. These views involve risks and uncertainties that are difficult to predict and, accordingly, our actual results may differ materially from the results discussed in such forward-looking statements. We caution you against relying on any of these forward-looking statements. In addition to the various factors included in the “Executive Level Overview,” “Critical Accounting Policies and Estimates” and “Outlook for the Company” sections, our future performance may be affected by our reliance on new home construction and home improvement, our reliance on key customers, the cost and availability of raw materials, shifts in consumer preferences and purchasing practices, our ability to improve our underperforming businesses and our ability to maintain our competitive position in our industries. These and other factors are discussed in detail in Item 1A “Risk Factors” of the previously filed 10-K. Any forward-looking statement made by us speaks only as of the date on which it was made. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. Unless required by law, we undertake no obligation to update publicly any forward-looking statements as a result of new information, future events or otherwise.

Executive Level Overview

We manufacture, distribute and install home improvement and building products. These products are sold for home improvement and new home construction through mass merchandisers, hardware stores, home centers, homebuilders, distributors and other outlets for consumers and contractors and direct to the consumer.

2012 Results. Net sales were positively affected by increased new home construction and repair and remodel (except for big ticket items) in the U.S., partially offset by slowing economic conditions in Europe and a stronger U.S. dollar. Our results of operations were positively affected by a more favorable relationship between selling prices and commodity costs and most of our businesses were positively affected by the benefits associated with the business rationalizations and cost savings initiatives that we have implemented over the last several years.

Our Cabinets and Related Products segment continues to be negatively affected by continuing competitive market conditions in repair and remodel in the U.S. and softness in Europe. Our Plumbing Products segment results were positively affected by the benefits of increased sales volume of our North American operations partially offset by lower sales volume and a less favorable product mix related to our international operations. The Decorative Architectural Products segment was positively affected by a more favorable relationship between selling prices and commodity costs and lower program costs. The Installation and Other Services segment was positively affected by increased sales volume. The Other Specialty Products segment was positively affected by a more favorable relationship between selling prices and commodity costs, partially offset by the exit of certain geographies. The Other Specialty Products segment was also negatively affected by incremental warranty expenses of $12 million and the impairment of a registered trademark of $42 million.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of these financial statements requires us to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of any contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We regularly review our estimates and assumptions, which are based upon historical experience, as well as current economic conditions and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of certain assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions.

We believe that the following critical accounting policies are affected by significant judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition and Receivables

We recognize revenue as title to products and risk of loss is transferred to customers or when services are rendered. We record revenue for unbilled services performed based upon estimates of material and labor incurred in the Installation and Other Services segment; such amounts are recorded in Receivables. We record estimated reductions to revenue for customer programs and incentive offerings, including special pricing and co-operative advertising arrangements, promotions and other volume-based incentives. We maintain allowances for doubtful accounts receivable for estimated losses resulting from the inability of customers to make required payments. In addition, we monitor our customer receivable balances and the credit worthiness of our customers on an on-going basis. During downturns in our markets, declines in the financial condition and creditworthiness of customers impact the credit risk of the receivables involved and we have incurred bad debt expense related to customer defaults. Our bad debt expense was $14 million, $12 million and $18 million for the years ended December 31, 2012, 2011 and 2010, respectively.

Inventories

We record inventories at the lower of cost or net realizable value, with expense estimates made for obsolescence or unsaleable inventory equal to the difference between the recorded cost of inventories and their estimated market value based upon assumptions about future demand and market conditions. On an on-going basis, we monitor these estimates and record adjustments for differences between estimates and actual experience. Historically, actual results have not significantly deviated from those determined using these estimates.

Financial Investments

We follow accounting guidance that defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements for our financial investments and liabilities. This guidance defines fair value as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Further, it defines a fair value hierarchy, as follows: Level 1 inputs as quoted prices in active markets for identical assets or liabilities; Level 2 inputs as observable inputs other than Level 1 prices, such as quoted market prices for similar assets or liabilities or other inputs that are observable or can be corroborated by market data; and Level 3 inputs as unobservable inputs that are supported by little or no market activity and that are financial instruments whose value is determined using pricing models or instruments for which the determination of fair value requires significant management judgment or estimation.

2

If applicable, we record investments in available-for-sale securities at fair value, and unrealized gains or losses (that are deemed to be temporary) are recognized, net of tax effect, through shareholders’ equity, as a component of other comprehensive income in our consolidated balance sheet.

In the past, we have invested excess cash in auction rate securities. Auction rate securities are investment securities that have interest rates which are reset every 7, 28 or 35 days. At December 31, 2012, our investment in auction rate securities was $22 million; we have not increased our investment in auction rate securities since 2007. The fair value of auction rate securities is estimated, on a recurring basis, using a discounted cash flow model (Level 3 input). If we changed the discount rate used in the fair value estimate by 75 basis points, the value of the auction rate securities would change by approximately $1 million.

We have maintained investments in a number of private equity funds, which aggregated $69 million at December 31, 2012. We carry our investments in private equity funds and other private investments at cost. It is not practicable for us to estimate a fair value for private equity funds and other private investments because there are no quoted market prices, and sufficient information is not readily available for us to utilize a valuation model to determine the fair value for each fund. These investments are evaluated, on a non-recurring basis, for potential other-than-temporary impairment when impairment indicators are present, or when an event or change in circumstances has occurred, that may have a significant adverse effect on the fair value of the investment. Due to the significant unobservable inputs, the fair value measurements used to evaluate impairment are a Level 3 input.

Impairment indicators we consider include the following: whether there has been a significant deterioration in earnings performance, asset quality or business prospects; a significant adverse change in the regulatory, economic or technological environment; a significant adverse change in the general market condition or geographic area in which the investment operates; industry and sector performance; current equity and credit market conditions; and any bona fide offers to purchase the investment for less than the carrying value. We also consider specific adverse conditions related to the financial health of and business outlook for the fund, including industry and sector performance. The significant assumptions utilized in analyzing a fund for potential other-than-temporary impairment include current economic conditions, market analysis for specific funds and performance indicators in residential and commercial construction, bio-technology, health care and information technology sectors in which the applicable funds’ investments operate.

At December 31, 2012, we have investments in 15 venture capital funds, with an aggregate carrying value of $16 million. The venture capital funds invest in start-up or smaller, early-stage established businesses, principally in the information technology, bio-technology and health care sectors. At December 31, 2012, we also have investments in 21 buyout funds, with an aggregate carrying value of $53 million. The buyout funds invest in later-stage, established businesses and no buyout fund has a concentration in a particular sector.

Since there is no active trading market for these investments, they are for the most part illiquid. These investments, by their nature, can also have a relatively higher degree of business risk, including financial leverage, than other financial investments. The timing of distributions from the funds, which depends on particular events related to the underlying investments, as well as the funds’ schedules for making distributions and their needs for cash, can be difficult to predict. As a result, the amount of income we record from these investments can vary substantially from quarter to quarter. Future changes in market conditions, the future performance of the underlying investments or new information provided by private equity fund managers could affect the recorded values of these investments and the amounts realized upon liquidation.

3

We record an impairment charge to earnings when an investment has experienced a decline in fair value that is deemed to be other-than-temporary.

Goodwill and Other Intangible Assets

We record the excess of purchase cost over the fair value of net tangible assets of acquired companies as goodwill or other identifiable intangible assets. In the fourth quarter of each year, or as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount, we complete the impairment testing of goodwill utilizing a discounted cash flow method. We selected the discounted cash flow methodology because we believe that it is comparable to what would be used by other market participants. We have defined our reporting units and completed the impairment testing of goodwill at the operating segment level, as defined by accounting guidance. Our operating segments are reporting units that engage in business activities for which discrete financial information, including five-year forecasts, is available.

Determining market values using a discounted cash flow method requires us to make significant estimates and assumptions, including long-term projections of cash flows, market conditions and appropriate discount rates. Our judgments are based upon historical experience, current market trends, consultations with external valuation specialists and other information. While we believe that the estimates and assumptions underlying the valuation methodology are reasonable, different estimates and assumptions could result in different outcomes. In estimating future cash flows, we rely on internally generated five-year forecasts for sales and operating profits, including capital expenditures, and generally a one to three percent long-term assumed annual growth rate of cash flows for periods after the five-year forecast. We generally develop these forecasts based upon, among other things, recent sales data for existing products, planned timing of new product launches, estimated housing starts and estimated repair and remodel activity.

In 2012, we utilized estimated housing starts, from independent industry sources, growing from current levels to 1.5 million units in 2017 (terminal growth year) and operating profit margins improving to approximate historical levels for those business units by 2017 (terminal growth year). We utilize our weighted average cost of capital of approximately 9.5 percent as the basis to determine the discount rate to apply to the estimated future cash flows. In 2012, due to market conditions and based upon our assessment of the risks impacting each of our businesses, we applied a risk premium to increase the discount rate to a range of 11 percent to 13 percent for most of our reporting units.

In the fourth quarter of 2012, we estimated that future discounted cash flows projected for all of our reporting units were greater than the carrying values. Any increases in estimated discounted cash flows would have no effect on the reported value of goodwill.

If the carrying amount of a reporting unit exceeds its fair value, we measure the possible goodwill impairment based upon an allocation of the estimate of fair value of the reporting unit to all of the underlying assets and liabilities of the reporting unit, including any previously unrecognized intangible assets (Step Two Analysis). The excess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill. An impairment loss is recognized to the extent that a reporting unit’s recorded goodwill exceeds the implied fair value of goodwill.

In 2012, we did not recognize any non-cash, pre-tax impairment charges for goodwill.

A ten percent decrease in the estimated fair value of our reporting units at December 31, 2012 would not have resulted in any additional analysis of goodwill impairment for any additional business unit.

4

We review our other indefinite-lived intangible assets for impairment annually, in the fourth quarter, or as events occur or circumstances change that indicate the assets may be impaired without regard to the reporting unit. We consider the implications of both external (e.g., market growth, competition and local economic conditions) and internal (e.g., product sales and expected product growth) factors and their potential impact on cash flows related to the intangible asset in both the near- and long-term. In 2012, we recognized non-cash, pre-tax impairment charges for other indefinite-lived intangible assets of $42 million ($27 million, after tax) attributable to our Other Specialty Products segment.

Intangible assets with finite useful lives are amortized using the straight-line method over their estimated useful lives. We evaluate the remaining useful lives of amortizable identifiable intangible assets at each reporting period to determine whether events and circumstances warrant a revision to the remaining periods of amortization.

Stock-Based Compensation

Our 2005 Plan provides for the issuance of stock-based incentives in various forms to employees and non-employee Directors. At December 31, 2012, outstanding stock-based incentives were in the form of long-term stock awards, stock options, phantom stock awards and stock appreciation rights.

Long-Term Stock Awards

We grant long-term stock awards to key employees and non-employee Directors and do not cause net share dilution inasmuch as we generally continue the practice of repurchasing and retiring an equal number of shares on the open market. We measure compensation expense for stock awards at the market price of our common stock at the grant date. There was $72 million (8 million common shares) of total unrecognized compensation expense related to unvested stock awards at December 31, 2012, which was included as a reduction of common stock and paid-in capital. Effective January 1, 2010, the vesting period for stock awards awarded after January 1, 2010 is five years. For stock awards granted prior to January 1, 2006, we recognize this expense over the vesting period of the stock awards, typically five to ten years, or for executive grantees that are, or will become, retirement-eligible during the vesting period, we recognize the expense over five years or immediately upon a grantee’s retirement. Effective January 1, 2006, we recognize this expense ratably over the shorter of the vesting period of the stock awards, typically five to ten years (except for stock awards held by grantees age 66 or older, which vest over five years), or the length of time until the grantee becomes retirement-eligible at age 65. Pre-tax compensation expense for the annual vesting of long-term stock awards was $35 million for 2012.

Stock Options

We grant stock options to 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 ten years after the grant date.

We measure compensation expense for stock options using a Black-Scholes option pricing model. We recognize this compensation expense ratably over the shorter of the vesting period of the stock options, typically five years, or the length of time until the grantee becomes retirement-eligible at age 65. Pre-tax compensation expense for stock options was $15 million for 2012.

We estimated the fair value of stock options at the grant date using a Black-Scholes option pricing model with the following assumptions for 2012: risk-free interest rate – 1.09%, dividend yield – 2.57%, volatility factor – 50.97% and expected option life – six years. For expense calculation purposes, the weighted average grant-date fair value of option shares granted in 2012 was $4.44 per option share.

If we increased our assumptions for the risk-free interest rate and the volatility factor by 50 percent, the expense related to the fair value of stock

5

options granted in 2012 would increase by 44 percent. If we lowered our assumptions for the risk-free interest rate and the volatility factor by 50 percent, the expense related to the fair value of stock options granted in 2012 would decrease by 55 percent.

Employee Retirement Plans

Effective January 1, 2010, we froze all future benefit accruals under substantially all of our domestic qualified and non-qualified defined-benefit pension plans. As a result of this action, the liabilities for these plans were remeasured; in addition, certain assumptions appropriate for on-going plans (e.g., turnover, mortality and compensation increases) have been modified or eliminated for the remeasurement.

Accounting for defined-benefit pension plans involves estimating the cost of benefits to be provided in the future, based upon vested years of service, and attributing those costs over the time period each employee works. We develop our pension costs and obligations from actuarial valuations. Inherent in these valuations are key assumptions regarding inflation, expected return on plan assets, mortality rates and discount rates for obligations and expenses. We consider current market conditions, including changes in interest rates, in selecting these assumptions. Changes in assumptions used could result in changes to reported pension costs and obligations within our consolidated financial statements.

In December 2012, we decreased our discount rate for obligations to an average of 3.80 percent from 4.40 percent. The discount rate for obligations is based upon the expected duration of each defined-benefit pension plan’s liabilities matched to the December 31, 2012 Towers Watson Rate Link curve. The discount rates we use for our defined-benefit pension plans ranged from 1.75 percent to 4.50 percent, with the most significant portion of the liabilities having a discount rate for obligations of 3.40 percent or higher. The assumed asset return was primarily 7.25 percent, reflecting the expected long-term return on plan assets.

Our net underfunded amount for our qualified defined-benefit pension plans, which is the difference between the projected benefit obligation and plan assets, increased to $462 million at December 31, 2012 from $439 million at December 31, 2011, primarily due to lower rates of return in the bond market in 2012. In accordance with accounting guidance, the underfunded amount has been recognized on our consolidated balance sheets at December 31, 2012 and 2011. Qualified domestic pension plan assets in 2012 had a net gain of approximately 17 percent compared to average gains of 13 percent for the Investor Force Defined Benefit Plan universe.

Our projected benefit obligation for our unfunded non-qualified defined-benefit pension plans was $181 million at December 31, 2012 compared with $174 million at December 31, 2011. In accordance with accounting guidance, this unfunded amount has been recognized on our consolidated balance sheets at December 31, 2012 and 2011.

At December 31, 2012, we reported a net liability of $643 million, of which $181 million was related to our non-qualified, supplemental retirement plans, which are not subject to the funding requirements of the Pension Protection Act of 2006. In accordance with the Pension Protection Act, the Adjusted Funding Target Attainment Percentage (“AFTAP”) for the various defined-benefit pension plans ranges from 71 percent to 84 percent.

We expect pension expense for our qualified defined-benefit pension plans to be $23 million in 2013 compared with $27 million in 2012. If we assumed that the future return on plan assets was one-half percent lower than the assumed asset return and the discount rate decreased by 50 basis points, the 2013 pension expense would increase by $4 million. We expect pension expense for our non-qualified defined-benefit pension plans to be $8 million in 2013 compared with $9 million in 2012.

We anticipate that we will be required to contribute approximately $50 million to $60 million in 2013 to our qualified and non-qualified defined-benefit plans.

Income Taxes

The accounting guidance for income taxes requires that the future realization of deferred tax assets depends on the existence of sufficient taxable income in future periods. Possible sources of taxable income include taxable income in carryback periods, the future reversal of existing taxable temporary differences recorded as a deferred tax liability, tax-planning strategies that generate future income or gains in excess of anticipated losses in the carryforward period and projected future taxable income.

If, based upon all available evidence, both positive and negative, it is more likely than not (more than 50 percent likely) such deferred tax assets will not be realized, a valuation allowance is recorded. Significant weight is given to positive and negative evidence that is objectively verifiable. A company’s three-year cumulative loss position is significant negative evidence in considering whether deferred tax assets are realizable and the accounting guidance restricts the amount of reliance we can place on projected taxable income to support the recovery of the deferred tax assets.

In the fourth quarter of 2010, we recorded a $372 million valuation allowance against our U.S. Federal deferred tax assets as a non-cash charge to income tax expense. In reaching this conclusion, we considered the weaker retail sales of certain of our building products and the slower than anticipated recovery in the U.S. housing market which led to U.S. operating losses and significant U.S. goodwill impairment charges, that primarily occurred in the fourth quarter of 2010, causing us to be in a three-year cumulative U.S. loss position.

During 2012 and 2011, objective and verifiable negative evidence, such as U.S. operating losses and significant impairment charges for U.S. goodwill in 2011 and other intangible assets, continued to outweigh positive evidence necessary to reduce the valuation allowance. As a result, we recorded increases of $65 million and $89 million in the valuation allowance related to our U.S. Federal deferred tax assets as a non-cash charge to income tax expense in 2012 and 2011, respectively.

Recording the valuation allowance does not restrict our ability to utilize the future deductions and net operating losses associated with the deferred tax assets assuming taxable income is recognized in future periods.

A rebound in the U.S. housing market from the recent historic lows and retail sales of building products improving from their current levels should have a positive impact on our operating results in the U.S. A return to sustained profitability in the U.S. should result in objective positive evidence thereby warranting the potential reversal of all or a portion of the valuation allowance.

The $203 million and $156 million of deferred tax assets at December 31, 2012 and 2011, respectively, for which there is no valuation allowance recorded, are anticipated to be realized through the future reversal of existing taxable temporary differences recorded as deferred tax liabilities.

Should we determine that we would not be able to realize our remaining deferred tax assets in the future, an adjustment to the valuation allowance would be recorded in the period such determination is made. The need to maintain a valuation allowance against deferred tax assets may cause greater volatility in our effective tax rate.

The current accounting guidance allows the recognition of only those income tax positions that have a greater than 50 percent likelihood of being sustained upon examination by the taxing authorities. We believe that there is an increased potential for volatility in our effective tax rate because this threshold allows changes in the income tax environment and the inherent complexities of income tax law in a substantial number of jurisdictions to affect the computation of our liability for uncertain tax positions to a greater extent.

7

While we believe we have adequately provided for our uncertain tax positions, amounts asserted by taxing authorities could vary from our liability for uncertain tax positions. Accordingly, additional provisions for tax-related matters, including interest and penalties, could be recorded in income tax expense in the period revised estimates are made or the underlying matters are settled or otherwise resolved.

Other Commitments and Contingencies

Warranty. At the time of sale, we accrue a warranty liability for the estimated cost to provide products, parts or services to repair or replace products in satisfaction of warranty obligations. Our estimate of costs to service our warranty obligations is based upon the information available and includes a number of factors such as the warranty coverage, the warranty period, historical experience specific to the nature, frequency and average cost to service the claim, along with product manufacturing metrics and industry and demographic trends.

Certain factors and related assumptions in determining our warranty liability involve judgments and estimates and are sensitive to changes in the aforementioned factors. We believe that the warranty accrual is appropriate; however, actual claims incurred could differ from the original estimates thereby requiring adjustments to previously established accruals.

A majority of our business is at the consumer retail level through home centers and major retailers. A consumer may return a product to a retail outlet that is a warranty return. However, certain retail outlets do not distinguish between warranty and other types of returns when they claim a return deduction from us. Our revenue recognition policy takes into account this type of return when recognizing revenue, and deductions are recorded at the time of sale.

We are subject to lawsuits and pending or asserted claims in the ordinary course of our business. Liabilities and costs associated with these matters require estimates and judgments based upon our professional knowledge and experience and that of our legal counsel. When estimates of our exposure for lawsuits and pending or asserted claims meet the criteria for recognition under accounting guidance, amounts are recorded as charges to earnings. The ultimate resolution of these exposures may differ due to subsequent developments. See Note T to our consolidated financial statements for information regarding certain of our legal proceedings.

Corporate Development Strategy

Our current business strategy includes the rationalization of our business units, including consolidations, and increasing synergies among our business units. Going forward, we expect to maintain a balanced growth strategy with emphasis on cash flow, organic growth with fewer acquisitions and growth through new product development and greenfield locations related to certain Installation and Other Services businesses.

As part of our strategic planning, we continue to review all of our businesses to determine which businesses may not be core to our long-term growth strategy. As a result, during 2012, we sold several business units in the Installation and Other Services segment. These businesses were related to commercial drywall installation, millwork and framing; accordingly, we accounted for these businesses as discontinued operations in 2012 and 2011.

In early February 2013, the Company determined that its Danish ready-to-assemble cabinet business was no longer core to its long-term growth strategy and, accordingly the Company embarked on a plan for disposition. The disposition is expected to be completed within the next 12 months.

See Note B to the consolidated financial statements for more information.

Liquidity and Capital Resources

Historically, we have largely funded our growth through cash provided by our operations, long-term bank debt and the issuance of notes in the financial markets, and by the issuance of our common stock, including issuances for certain mergers and acquisitions.

Maintaining high levels of liquidity and focusing on cash generation are among our financial strategies; as a result, we have cash of approximately $1.4 billion at December 31, 2012. Our total debt as a percent of total capitalization was 87 percent and 84 percent at December 31, 2012 and 2011, respectively.

We maintain a Credit Agreement (the “Credit Agreement”) with a bank group, with an aggregate commitment of $1.25 billion and a maturity date of January 10, 2014. The 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.

We have entered into two amendments of the Credit Agreement. The amendments provided for the add-back to shareholders’ equity in our debt to capitalization covenant of certain non-cash charges, changes to the valuation allowance on our deferred tax assets included in income tax expense, and certain future non-cash charges. The second amendment also revised the permitted ratio of consolidated EBITDA to the consolidated interest expense to 2.25 to 1.00 through December 31, 2012, increasing to 2.50 to 1.00 with respect to each quarter thereafter.

At December 31, 2012, we had additional borrowing capacity, subject to availability, of up to $873 million. Alternatively, at December 31, 2012, we could absorb a reduction to shareholders’ equity of approximately $470 million and remain in compliance with the debt to total capitalization covenant. We were in compliance with all Credit Agreement covenants and we had no borrowings under the Credit Agreement at December 31, 2012.

On March 5, 2012, we issued $400 million of 5.95% Notes due March 15, 2022 (“the Notes”). Including the interest rate swap amortization, the effective interest rate for the Notes is approximately 6.5%. The Notes are senior indebtedness and are redeemable at the Company’s option.

In January 2012, we repurchased $46 million of 5.875% Notes due July 15, 2012 in open-market transactions; we paid a premium of $1 million for the repurchase. In July 2012, we retired all of our $745 million of 5.875% Notes on the scheduled retirement date.

We had cash and cash investments of approximately $1.4 billion at December 31, 2012. Our cash and cash investments consist of overnight interest bearing money market demand and time deposit accounts, money market mutual funds containing government securities and treasury obligations. While we attempt to diversify these investments in a prudent manner to minimize risk, it is possible that future changes in the financial markets could affect the security or availability of these investments.

Of the $1.4 billion and the $1.7 billion of cash and cash investments we held at December 31, 2012 and 2011, respectively, $572 million and $551 million, respectively, is held in our foreign subsidiaries. If these funds were needed for our operations in the U.S., their repatriation into the U.S. may result in additional U.S. income taxes or foreign withholding taxes. The amount of such taxes is dependent on the income tax laws and circumstances at the time of distribution.

We have maintained investments in available-for-sale and marketable securities and a number of private equity funds, principally as part of our tax planning strategies, as any gains enhance the utilization of any current and future capital tax losses. We determined that the longer maturity of private equity funds would be advantageous and complement our investment in more liquid available-for-sale and

9

marketable securities to balance risk. Since we have significantly reduced our capital tax losses in part by generating capital gains from investments and other sources, we have and will continue to reduce our investments in long-term financial assets.

We utilize derivative and hedging instruments to manage our exposure to currency fluctuations, primarily related to the European euro and the U.S. dollar; commodity cost fluctuations, primarily zinc and copper; and interest rate fluctuations, primarily related to debt issuances. We review our hedging program, derivative positions and overall risk management on a regular basis.

During 2012, we paid quarterly dividends of $.075 per common share.

Our working capital ratio was 1.7 to 1 and 1.5 to 1 at December 31, 2012 and 2011, respectively. The increase in the working capital ratio is primarily due to the payment of $791 million of 5.875% Notes in July 2012, which were included in current liabilities at December 31, 2011, partially offset by the short-term classification of $200 million Notes due August 2013.

Cash Flows

Significant sources and (uses) of cash in the past three years are summarized as follows, in millions:

	2012			2011			2010
Net cash from operating activities	$	281		$	239		$	465

Other, net		(24	)		(19	)		(41	)
Cash (decrease) increase	$	(305	)	$	(59	)	$	302

Our cash and cash investments decreased $305 million to $1,351 million at December 31, 2012, from $1,656 million at December 31, 2011.

Net cash provided by operations of $281 million consisted primarily of net (loss) adjusted for non-cash and certain other items, including depreciation and amortization expense of $214 million, a $42 million charge for the impairment of other intangible assets, a $50 million net change in deferred taxes and other non-cash items, including stock-based compensation expense and amortization expense related to in-store displays.

We continue to emphasize balance sheet management, including working capital management and cash flow generation. Days sales in accounts receivable were 47 days at both December 31, 2012 and 2011, and days sales in inventories were 52 days at both December 31, 2012 and 2011. Accounts payable days were 66 days at December 31, 2012 and 63 days at December 31, 2011; the increase in payable days is due to our improved management of accounts payable. Working capital (defined as accounts receivable and inventories less accounts payable) as a percent of sales was 11.6 percent at December 31, 2012 and 11.9 percent at December 31, 2011.

10

Net cash used for financing activities was $576 million, primarily due to the retirement of $791 million of 5.875% Notes due July 15, 2012, $107 million for cash dividends paid, $25 million for the settlement of interest rate swaps and $8 million for the acquisition of our common stock to generally offset the dilutive impact of long-term stock awards granted in 2012, partially offset by the issuance of Notes for $396 million, net of issuance costs.

At December 31, 2012, we had remaining authorization from our Board of Directors to repurchase up to an additional 24 million shares of our common stock in open-market transactions or otherwise. We believe that our present cash balance and cash flows from operations 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. Consistent with past practice, we anticipate repurchasing shares in 2013 to offset any dilution from long-term stock awards granted or stock options exercised as part of our compensation programs.

Net cash used for investing activities was $27 million, and included $119 million for capital expenditures. Cash provided by investing activities included primarily $67 million of net proceeds from the disposition of property and equipment and $40 million from the net sale of financial investments.

We invest in automating our manufacturing operations to increase our productivity, improve customer service and support new product innovation. Capital expenditures for 2012 were $119 million, compared with $151 million for 2011 and $137 million for 2010; for 2013, capital expenditures, excluding any potential 2013 acquisitions, are expected to be approximately $165 million. Depreciation and amortization expense for 2012 totaled $214 million, compared with $263 million for 2011 and $279 million for 2010; for 2013, depreciation and amortization expense, excluding any potential 2013 acquisitions, is expected to be approximately $210 million. Amortization expense totaled $12 million, $17 million and $18 million in 2012, 2011 and 2010, respectively.

Costs of environmental responsibilities and compliance with existing environmental laws and regulations have not had, nor do we expect them to have, a material effect on our capital expenditures, financial position or results of operations.

Consolidated Results of Operations

We report our financial results in accordance with 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.

Sales and Operations

Net sales for 2012 were $7.5 billion, which increased five percent compared with 2011. Excluding results from acquisitions and the negative effect of currency translation, net sales increased six percent compared with 2011. The following table reconciles reported net sales to net sales excluding acquisitions and the effect of currency translation, in millions:

	Twelve Months Ended December 31
	2012			2011
Net sales, as reported	$	7,495		$	7,170
- Acquisitions		(16	)		—
Net sales, excluding acquisitions		7,479			7,170
- Currency translation		99			—
Net sales, excluding acquisitions and the effect of currency	$	7,578		$	7,170

Net sales for 2012 were positively affected by increased sales volume of installed products, North American plumbing products, paints and stains, builders’ hardware and windows, which, in aggregate, increased sales by approximately four percent compared to 2011. Net sales for 2012 were also positively affected by selling price increases, which increased sales by approximately three percent. Net sales for 2012 were negatively affected by the planned exit of certain cabinet and window product lines in certain geographic areas. A stronger U.S. dollar decreased sales by one percent compared to 2011.

Net sales for 2011 were adversely affected by lower sales volume of installed products, cabinets, paints and stains, builders’ hardware and windows, which, in aggregate, reduced sales by approximately three percent compared to 2010. Net sales for 2011 were also adversely affected by the planned exit of certain cabinet product lines, which reduced sales by approximately two percent compared to 2010. Such declines were partially offset by selling price increases, primarily related to plumbing products and paints and stains, which increased sales by approximately three percent. A weaker U.S. dollar increased sales by one percent compared to 2010.

Our gross profit margins were 26.1 percent, 24.9 percent and 25.1 percent in 2012, 2011 and 2010, respectively. The 2012 gross profit margin reflects a more favorable relationship between selling prices and commodity costs as well as increased sales volume. The decrease in the 2011 gross profit margin reflects lower sales volume and a less favorable relationship between selling prices and commodity costs. Both 2012 and 2011 reflect the benefits associated with business rationalizations and other cost savings initiatives.

Selling, general and administrative expenses as a percent of sales were 20.5 percent in 2012 compared with 21.5 percent in 2011 and 21.9 percent in 2010. Selling, general and administrative expenses as a percent of sales in 2012 reflect increased sales volume and lower business rationalization costs. Selling, general and administrative expenses as a percent of sales in 2011 reflect increased expenses related to growth initiatives, offset by lower business rationalization expenses. Both 2012 and 2011 reflect the benefits associated with our business rationalizations and other cost savings initiatives.

Operating profit (loss) in 2012, 2011 and 2010 includes $75 million, $111 million and $207 million, respectively, of costs and charges related to business rationalizations and other cost savings initiatives. Operating profit (loss) in 2012, 2011 and 2010 includes $42 million, $450 million and $698 million, respectively, of impairment charges for goodwill and other intangible assets. Operating profit (loss) in 2012 and 2011 includes $77 million and $9 million, respectively, of net charges for litigation settlements. Operating profit (loss) in 2012 includes $8 million of net

12

gains related to fixed asset sales. Operating profit (loss) margins, as reported, were 4.0 percent, (3.0) percent and (6.5) percent in 2012, 2011 and 2010, respectively. Operating profit margins, excluding the items above, were 6.5 percent, 5.0 percent and 6.1 percent in 2012, 2011 and 2010, respectively.

Operating margins in 2012 were positively affected by a more favorable relationship between selling prices and commodity costs, increased sales volume and the benefits associated with business rationalizations and other cost savings initiatives.

Operating margins in 2011 were negatively affected by a less favorable relationship between selling prices and commodity costs, a less favorable product mix and increased expenses related to growth initiatives. Such decreases more than offset lower business rationalization costs and the benefits associated with such expenses.

Other Income (Expense), Net

Other, net, for 2012 included gains of $24 million from financial investments, net. During 2012, we recognized non-cash, pre-tax impairment charges aggregating $2 million for an investment in a private equity fund. Other, net, for 2012 also included realized foreign currency losses of $2 million and other miscellaneous items.

During 2011, we recognized gains of $41 million related to the sale of TriMas common stock. We also recognized gains of $32 million related to distributions from private equity funds.

Other, net, for 2011 also included realized foreign currency losses of $5 million and other miscellaneous items.

During 2010, we recognized non-cash, pre-tax impairment charges aggregating $34 million related to financial investments ($28 million related to Asahi Tec preferred stock and $6 million related to private equity funds and other private investments).

Other, net, for 2010 included $9 million of income from financial investments, net. Other, net, for 2010 also included realized foreign currency losses of $3 million and other miscellaneous items.

Interest expense was $254 million, $254 million and $251 million in 2012, 2011 and 2010, respectively.

(Loss) Income and (Loss) Earnings Per Common Share from Continuing Operations (Attributable to Masco Corporation)

(Loss) and diluted (loss) per common share from continuing operations for 2012 were $(53) million and $(.16) per common share, respectively. (Loss) and diluted (loss) per common share from continuing operations for 2011 were $(394) million and $(1.14) per common share, respectively. (Loss) and diluted (loss) per common share from continuing operations for 2010 were $(1,027) million and $(2.95) per common share, respectively. (Loss) from continuing operations for 2012 included non-cash, pre-tax impairment charges for other intangible assets of $42 million ($27 million or $.08 per common share, after tax). (Loss) from continuing operations for 2011 included non-cash, pre-tax impairment charges for goodwill and other intangible assets of $450 million ($291 million or $.84 per common share, after tax). (Loss) from continuing operations for 2010 included non-cash, pre-tax impairment charges for goodwill and other intangible assets of $698 million ($586 million or $1.68 per common share, after tax).

Our effective tax rate for the loss from continuing operations was a 125 percent tax expense, a 10 percent tax benefit, and a 32 percent tax expense in 2012, 2011 and 2010, respectively. Compared to our normalized effective tax rate of 36 percent, the variance in the effective tax rate in 2012, 2011 and 2010 is due primarily to changes in the U.S. Federal valuation allowance, reversal of an accrual for uncertain tax positions and intangible asset impairment charges providing no tax benefit.

Outlook for the Company

We continue to make progress on our strategic initiatives, which include expanding our product leadership positions, reducing our costs, improving our Installation and Cabinet segments and strengthening our balance sheet. We believe these initiatives, coupled with the actions we have taken over the past several years, should position us for improved results in 2013, and continue to believe that we will outperform as new home construction and repair and remodel recover.

We believe and are confident that the long-term fundamentals for new home construction and home improvement activity continue to be positive. We believe that our strong financial position, together with our current strategy of investing in leadership brands, including KRAFTMAID and MERILLAT cabinets, DELTA and HANSGROHE faucets, BEHR paint and MILGARD windows, our continued focus on innovation and our commitment to lean principles, will allow us to drive long-term growth and create value for our shareholders.

Business Rationalizations and Other Initiatives

Over the past several years, we have been focused on the strategic rationalization of our businesses, including business consolidations, plant closures, headcount reductions, system implementations and other cost savings initiatives. For the years ended December 31, 2012, 2011 and 2010, we incurred net pre-tax costs and charges related to these initiatives of $75 million, $111 million and $207 million, respectively.

During 2012, our North American cabinet business continued to incur costs and charges of $33 million related to the closure of its countertop manufacturing facility (as a result of our strategic change to a sourcing model for countertops), the closure of a cabinet components facility and additional headcount reductions. Our Plumbing Products segment incurred costs of $25 million related to a plant closure and severance in our bathing systems business in North America and a plant closure and severance in Spain. We also incurred $14 million in costs related to severance actions at our corporate office. Finally, we incurred $3 million of costs and charges across our business units related to other cost savings initiatives.

During 2011, our North American cabinet business continued to incur costs and charges of $24 million related to the exit of its ready-to-assemble product line and $6 million related to the integration of its facilities. Our Installation and Other Services segment incurred costs and charges of $4 million related to the closure of several locations and further headcount reductions. Our builders’ hardware business in the Decorative Architectural Products segment incurred costs and charges of $9 million related to the exit of a product line. Our North American window manufacturer incurred costs and charges of $30 million related to the closure of several manufacturing facilities.

In 2010, we took several actions within the Cabinets and Related Products segment to rationalize our North American manufacturers, including closing plants, exiting product lines and integrating our Builder and Retail Cabinet Groups. We incurred costs and charges of $171 million in 2010 related to these actions.

In the fourth quarter of 2011, we decided to dispose of several non-core businesses in the Installation and Other Services segment. These businesses were related to commercial drywall installation, millwork and framing, and were classified as discontinued operations for all periods. During 2012, we sold all of these businesses, for net proceeds of $7 million.

Based on current plans, we anticipate costs and charges related to our business rationalizations and other initiatives to approximate $40 million in 2013. We continue to evaluate our businesses and may implement additional rationalization programs based on changes in our markets which could result in further costs and charges.

In early February 2013, we determined that our Danish ready-to-assemble cabinet business was no longer core to our long-term growth strategy and, accordingly we embarked on a plan for disposition. This business unit had 2012 sales of approximately $250 million and an operating loss of approximately $30 million. The disposition is expected to be completed within the next 12 months.

Cabinets and Related Products

Sales

Net sales of Cabinets and Related Products increased primarily due to increased sales volume of North American operations and by increased selling prices, which increased sales by one percent compared to 2011.

Net sales in this segment decreased in 2011 primarily due to lower sales volumes of North American cabinets, which reduced sales by approximately six percent compared to 2010. Sales in this segment in 2011 were also negatively affected by the planned exit of North American ready-to-assemble and other non-core in-stock assembled cabinet product lines, particle board and door product lines, which reduced sales by approximately 14 percent compared to 2010. Sales were also negatively affected by lower sales volume of international cabinets, which reduced sales in this segment by approximately one percent compared to 2010.

Net sales in this segment in 2010 were negatively affected by lower sales volumes of North American and international cabinets and the planned exit of ready-to-assemble and other non-core in-stock assembled cabinet product lines, particle board and door product lines.

Operating Results

Operating margins in the Cabinets and Related Products segment in 2012 were positively affected by lower business rationalization expenses and the benefits associated with such expenses incurred in prior years.

Operating margins in this segment in 2011 were positively affected by lower business rationalization expenses and the benefits associated with such expenses, including benefits related to the integration of the North American cabinet businesses. Such increases were partially offset by a less favorable relationship between selling prices and commodity costs, aggressive promotional activity and lower sales volume and the related under-absorption of fixed costs.

Operating margins in this segment in 2010 were negatively affected by lower sales volume and the related under-absorption of fixed costs, which reduced operating profit margins by approximately three percentage points. Operating profit margins in this segment in 2010 were also negatively affected by increased business rationalization expenses and a less favorable relationship between selling prices and commodity costs; such decreases more than offset the benefits associated with business rationalizations and other cost savings initiatives.

Plumbing Products

Sales

Net sales of Plumbing Products increased in 2012 primarily due to increased sales volume of North American operations and increased selling prices, which, in aggregate, increased sales by approximately five percent compared to 2011. Lower sales volume of international operations decreased sales in this segment by one percent from 2011. A stronger U.S. dollar decreased sales by three percent in 2012 compared to 2011.

Net sales in this segment increased in 2011 primarily due to increased selling prices, which increased sales by approximately three percent compared to 2010. Sales were also positively affected by increased sales volume in North America and International, which, in aggregate, increased sales by approximately three percent compared to 2010. A weaker U.S. dollar increased sales by two percent in 2011 compared to 2010.

Net sales in this segment in 2010 were positively affected by a more favorable product mix to North American retailers and wholesalers, increased selling prices, and sales of International operations. Such increases were partially offset by lower sales volume to North American retailers and wholesalers.

17

Operating Results

Operating margins in the Plumbing Products segment in 2012 were negatively affected by lower sales volume and a less favorable product mix principally related to international operations. Such declines more than offset increased North American sales volume and a more favorable relationship between selling prices and commodity costs.

Operating margins in this segment in 2011 were negatively affected by a less favorable relationship between selling prices and commodity costs, a less favorable product mix and increased expenses related to growth initiatives which offset the benefits associated with business rationalizations and other cost savings initiatives.

Operating margins in this segment in 2010 were positively affected by a more favorable product mix and the positive relationship between selling prices and commodity costs and the benefits associated with business rationalizations and other cost savings initiatives.

Installation and Other Services

Sales

Net sales in the Installation and Other Services segment increased in 2012 primarily due to increased sales volume related to a higher level of activity in the new home construction market and increased commercial sales.

Net sales in this segment increased in 2011 primarily due to increased distribution sales, increased selling prices and increased retrofit and commercial sales. Such increases were partially offset by lower sales volume of installed products related to a continued decline in the new home construction market, the downward trend in the size and content of new houses in early 2011 and the increased multi-family construction; we gained share in single-family construction.

Net sales in this segment decreased in 2010 primarily due to lower sales volume related to reduced share in the new home construction market. Sales in this segment were also negatively affected by a downward trend in the size and content of new houses being constructed by our builder customers.

Operating Results

Operating margins in the Installation and Other Services segment in 2012 were positively affected by increased sales volume and the related absorption of fixed costs, as well as the benefits associated with business rationalizations and other cost savings initiatives.

Operating margins in the Installation and Other Services segment in 2011 were positively affected by increased sales volume, the benefits associated with business rationalizations and other cost savings initiatives and a more favorable relationship between selling prices and commodity costs.

Operating margins in this segment in 2010 were negatively affected by lower sales volume in the new home construction market and the related under-absorption of fixed costs, as well as a less favorable relationship between selling prices and commodity costs. Such declines were partially offset by the benefits associated with business rationalization and other cost savings initiatives and lower system implementation costs in 2010.

Decorative Architectural Products

Sales

Net sales of Decorative Architectural Products increased in 2012, primarily due to increased selling prices of paints and stains, as well as increased sales volume of paints and stains and builders’ hardware.

18

Net sales in this segment decreased in 2011, primarily due to lower sales volume of paints and stains and builders’ hardware. Such declines in 2011 were partially offset by increased selling prices of paints and stains.

Net sales in this segment in 2010 were negatively affected by lower sales volume of builders’ hardware and lower selling prices of paints and stains, partially offset by a more favorable product mix of paints and stains, related to new product introductions.

Operating Results

Operating margins in the Decorative Architectural Products segment in 2012 reflect a more favorable product mix, a more favorable relationship between selling prices and commodity costs related to paints and stains and lower program costs related to builders’ hardware.

Operating margins in this segment in 2011 were negatively affected by a less favorable relationship between selling prices and commodity costs related to paints and stains and increased expenses related to growth initiatives. This segment was also negatively affected by increased business rationalization expenses related to the exit of a builders’ hardware product line.

Operating margins in this segment in 2010 were negatively affected by a less favorable relationship between selling prices and commodity costs related to paints and stains, as well as lower sales volume of builders’ hardware. Such declines more than offset the benefit of a more favorable product mix of paints and stains, related to new product introductions.

Other Specialty Products

Sales

Net sales of Other Specialty Products were flat in 2012 primarily due to increased sales volume of windows in Western markets in the U.S., a more favorable product mix and increased selling prices which were offset by lower sales volume of North American windows resulting from the exit of certain markets.

Net sales in this segment decreased in 2011 primarily due to lower sales volume of windows in North America (due to the expiration of the energy tax credit in 2010) and the U.K., partially offset by increased selling prices and increased sales related to new product introductions and geographic expansion. A weaker U.S. dollar increased sales in this segment by one percent compared to 2010.

Net sales in this segment increased in 2010 primarily due to increased sales volume of windows in North America, principally related to the energy-savings tax credit which expired at the end of 2010, and increased sales volume of staple gun tackers and other fastening tools.

Operating Results

Operating results in the Other Specialty Products segment in 2012 were positively affected by the benefits associated with business rationalizations and other cost savings initiatives, lower business rationalization costs and a more favorable relationship between selling prices and commodity costs. These items more than offset the increased warranty expense of $12 million.

Operating margins in this segment in 2011 were negatively affected by increased business rationalization expenses, lower sales volume and increased product launch and geographic expansion costs. Such decreases offset a more favorable relationship between selling prices and commodity costs and the benefits associated with business rationalizations and other cost savings initiatives.

Operating margins in this segment in 2010 reflect the negative effect of a less favorable relationship between selling prices and commodity costs and a less favorable windows product mix. Such declines offset the benefits associated with business rationalizations and other cost savings initiatives.

19

Geographic Area Results Discussion

North America

Sales

North American net sales in 2012 were positively impacted by increased sales volume of installation and other services, plumbing products, paints and stains, builders’ hardware and windows, which, in the aggregate, increased sales by approximately four percent compared to 2011. Net sales were also positively affected by increased selling prices of plumbing products and paints and stains, which increased sales by approximately three percent compared to 2011.

North American net sales in 2011 were negatively impacted by lower sales volume of cabinets, including the planned exit of certain product lines, paints and stains, builders’ hardware and windows, which, in the aggregate, decreased sales by approximately six percent compared to 2010. Such declines were partially offset by increased selling prices of plumbing products and paints and stains, which increased sales by approximately three percent compared to 2010.

North American net sales in 2010 were negatively impacted by lower sales volume of installation and other services, cabinets, plumbing products, and builders’ hardware, partially offset by a more favorable product mix of plumbing products and paints and stains, which increased sales by approximately one percent compared to 2009.

Operating Results

Operating margins from North American operations in 2012 were positively affected by a more favorable relationship between selling prices and commodity costs, lower business rationalization expenses and the benefits associated with business rationalization and other cost savings initiatives which, in aggregate, increased operating margins by three percentage points.

Operating margins from North American operations in 2011 were positively affected by lower business rationalization expenses and the benefits associated with business rationalization and other cost savings initiatives, which increased operating margins by two percentage points. Such increases offset the negative impact of lower sales volume and the related under-absorption of fixed costs and a less favorable relationship between selling prices and commodity costs which, in the aggregate, decreased operating profit margins by one percentage point in 2011 compared to 2010.

Operating margins from North American operations in 2010 were negatively affected by lower sales volume and the related under-absorption of fixed costs and a less favorable relationship between selling prices and commodity costs, which decreased operating profit margins by two percentage points in 2010 compared to 2009. Operating margins were also negatively affected by increased business rationalization costs and charges in 2010 compared to 2009.

20

International, Principally Europe

Sales

Net sales from international operations in 2012 increased three percent in local currencies compared to 2011, primarily due to increased selling prices, partially offset by lower sales volume of plumbing products, cabinets and windows. A stronger U.S. dollar decreased International net sales by seven percent in 2012 compared to 2011.

Net sales from international operations increased in local currencies in 2011 by approximately four percent compared to 2010, primarily due to increased sales volume and increased selling prices of International plumbing products, offset by lower sales volume of International cabinets. A weaker U.S. dollar increased International net sales by six percent in 2011 compared to 2010.

Net sales from international operations increased in local currencies in 2010, primarily due to increased sales volume and increased selling prices of International plumbing products and windows, offset by lower sales volume of International cabinets.

Operating Results

Operating profit margins from international operations in 2011 were negatively affected by a less favorable product mix and a less favorable relationship between selling prices and commodity costs, offset by the benefits associated with business rationalizations and other cost savings initiatives.

Operating profit margins from international operations in 2010 were negatively affected by a less favorable product mix, partially offset by the benefits associated with business rationalizations and other cost savings initiatives.

Other Matters

Commitments and Contingencies

Litigation

Information regarding our legal proceedings is set forth in Note T to the consolidated financial statements, which is incorporated herein by reference.

Other Commitments

With respect to our investments in private equity funds, we had, at December 31, 2012, commitments to contribute up to $19 million of additional capital to such funds, representing our aggregate capital commitment to such funds less capital contributions made to date. We are contractually obligated to make additional capital contributions to these private equity funds upon receipt of a capital call from the private equity fund. We have no control over when or if the capital calls will occur. Capital calls are funded in cash and generally result in an increase in the carrying value of our investment in the private equity fund when paid.

We enter into contracts, which include reasonable and customary indemnifications that are standard for the industries in which we operate. Such indemnifications include claims made against builders by homeowners for issues relating to our products and workmanship. In conjunction with divestitures and other transactions, we occasionally provide reasonable and customary indemnifications relating to various items, including: the enforceability of trademarks; legal and environmental issues; and provisions for sales returns. We have never had to pay a material amount related to these indemnifications, and we evaluate the probability that amounts may be incurred and we appropriately record an estimated liability when probable.

(B) There is no schedule for the capital commitments to the private equity funds; such allocation was estimated.

(C) Excludes contracts that do not require volume commitments and open or pending purchase orders.

(D) Due to the high degree of uncertainty regarding the timing of future cash outflows associated with uncertain tax positions, we are unable to make a reasonable estimate for the period beyond the next year in which cash settlements may occur with applicable tax authorities.

Refer to Footnote M of our financial statements for defined-benefit plan obligations.

Recently Issued Accounting Pronouncements. On January 1, 2012, we adopted new accounting guidance requiring more prominent presentation of other comprehensive income items in our consolidated financial statements. The adoption of this new guidance did not have an impact on our financial position or our results of operations.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk.

We have considered the provisions of accounting guidance regarding disclosure of accounting policies for derivative financial instruments and derivative commodity instruments, and disclosure of quantitative and qualitative information about market risk inherent in derivative financial instruments, other financial instruments and derivative commodity instruments.

We are exposed to the impact of changes in interest rates, foreign currency exchange rates and commodity costs in the normal course of business and to market price fluctuations related to our financial investments. We have involvement with derivative financial instruments and use such instruments to the extent necessary to manage exposure to foreign currency fluctuations and commodity fluctuations. See Note F to the consolidated financial statements for additional information regarding our derivative instruments.

At December 31, 2012, we performed sensitivity analyses to assess the potential loss in the fair values of market risk sensitive instruments resulting from a hypothetical change of 10 percent in foreign currency exchange rates, a 10 percent decline in the market value of our long-term investments, a 10 percent change in commodity costs, or a 10 percent change in interest rates. Based upon the analyses performed, such changes would not be expected to materially affect our consolidated financial position, results of operations or cash flows.

Exhibit 99.3

Item 8. Financial Statements and Supplementary Data

Management’s Report on Internal Control Over Financial Reporting

The management of Masco Corporation is responsible for establishing and maintaining adequate internal control over financial reporting. Masco Corporation’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

The management of Masco Corporation assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2012 using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in “Internal Control – Integrated Framework.” Based on this assessment, management has determined that the Company’s internal control over financial reporting was effective as of December 31, 2012.

PricewaterhouseCoopers LLP, an independent registered public accounting firm, performed an audit of the Company’s consolidated financial statements and of the effectiveness of Masco Corporation’s internal control over financial reporting as of December 31, 2012. Their report expressed an unqualified opinion on the effectiveness of Masco Corporation’s internal control over financial reporting as of December 31, 2012 and expressed an unqualified opinion on the Company’s 2012 consolidated financial statements. This report appears under Item 8. Financial Statements and Supplementary Data under the heading Report of Independent Registered Public Accounting Firm.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders

of Masco Corporation:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, comprehensive loss, shareholders’ equity and cash flows present fairly, in all material respects, the financial position of Masco Corporation and its subsidiaries at December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the accompanying financial statement schedule presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 8. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A. ACCOUNTING POLICIES

Principles of Consolidation. The consolidated financial statements include the accounts of Masco Corporation and all majority-owned subsidiaries. All significant intercompany transactions have been eliminated. The Company consolidates the assets, liabilities and results of operations of variable interest entities, for which the Company is the primary beneficiary.

Use of Estimates and Assumptions in the Preparation of Financial Statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of any contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates and assumptions.

Revenue Recognition. The Company recognizes revenue as title to products and risk of loss is transferred to customers or when services are rendered, net of applicable provisions for discounts, returns and allowances. The Company records revenue for unbilled services performed based upon material and labor incurred in the Installation and Other Services segment; such amounts are recorded in Receivables. Amounts billed for shipping and handling are included in net sales, while costs incurred for shipping and handling are included in cost of sales.

Customer Promotion Costs. The Company records estimated reductions to revenue for customer programs and incentive offerings, including special pricing and co-operative advertising arrangements, promotions and other volume-based incentives. In-store displays that are owned by the Company and used to market the Company’s products are included in other assets in the consolidated balance sheets and are amortized using the straight-line method over the expected useful life of three to five years; related amortization expense is classified as a selling expense in the consolidated statements of operations.

Foreign Currency. The financial statements of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities of these subsidiaries are translated at exchange rates as of the balance sheet date. Revenues and expenses are translated at average exchange rates in effect during the year. The resulting cumulative translation adjustments have been recorded in the accumulated other comprehensive income component of shareholders’ equity. Realized foreign currency transaction gains and losses are included in the consolidated statements of operations in other income (expense), net.

Cash and Cash Investments. The Company considers all highly liquid investments with an initial maturity of three months or less to be cash and cash investments.

A. ACCOUNTING POLICIES (Continued)

Receivables. The Company does significant business with a number of customers, including certain home centers and homebuilders. The Company monitors its exposure for credit losses on its customer receivable balances and the credit worthiness of its customers on an on-going basis and records related allowances for doubtful accounts. Allowances are estimated based upon specific customer balances, where a risk of default has been identified, and also include a provision for non-customer specific defaults based upon historical collection, return and write-off activity. During downturns in the Company’s markets, declines in the financial condition and creditworthiness of customers impacts the credit risk of the receivables involved and the Company has incurred additional bad debt expense related to customer defaults. A separate allowance is recorded for customer incentive rebates and is generally based upon sales activity. Receivables are presented net of certain allowances (including allowances for doubtful accounts) of $71 million and $59 million at December 31, 2012 and 2011, respectively. Receivables include unbilled revenue related to the Installation and Other Services segment of $18 million and $17 million at December 31, 2012 and 2011, respectively.

Property and Equipment. Property and equipment, including significant betterments to existing facilities, are recorded at cost. Upon retirement or disposal, the cost and accumulated depreciation are removed from the accounts and any gain or loss is included in the consolidated statements of operations. Maintenance and repair costs are charged against earnings as incurred.

The Company reviews its property and equipment as an event occurs or circumstances change that would more likely than not reduce the fair value of the property and equipment below the carrying amount. If the carrying amount of property and equipment is not recoverable from its undiscounted cash flows, then the Company would recognize an impairment loss for the difference between the carrying amount and the current fair value. Further, the Company evaluates the remaining useful lives of property and equipment at each reporting period to determine whether events and circumstances warrant a revision to the remaining depreciation periods.

Depreciation. Depreciation expense is computed principally using the straight-line method over the estimated useful lives of the assets. Annual depreciation rates are as follows: buildings and land improvements, 2 to 10 percent, and machinery and equipment, 5 to 33 percent. Depreciation expense was $192 million, $234 million and $249 million in 2012, 2011 and 2010, respectively. Such depreciation expense included accelerated depreciation of $28 million (primarily in the Cabinets and Related Products and Plumbing Products segments), $52 million (primarily in the Cabinets and Related Products and Other Specialty Products segments) and $43 million (primarily in the Cabinets and Related Products segment) in 2012, 2011 and 2010, respectively.

Goodwill and Other Intangible Assets. The Company performs its annual impairment testing of goodwill in the fourth quarter of each year, or as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company has defined its reporting units and completed the impairment testing of goodwill at the operating segment level. The Company’s operating segments are reporting units that engage in business activities, for which discrete financial information, including five-year forecasts, are available. The Company compares the fair value of the reporting units to the carrying value of the reporting units for goodwill impairment testing. Fair value is determined using a discounted cash flow method, which includes significant unobservable inputs (Level 3 inputs).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

A. ACCOUNTING POLICIES (Continued)

Determining market values using a discounted cash flow method requires the Company to make significant estimates and assumptions, including long-term projections of cash flows, market conditions and appropriate discount rates. The Company’s judgments are based upon historical experience, current market trends, consultations with external valuation specialists and other information. In estimating future cash flows, the Company relies on internally generated five-year forecasts for sales and operating profits, including capital expenditures, and generally a one to three percent long-term assumed annual growth rate of cash flows for periods after the five-year forecast. The Company utilizes its weighted average cost of capital of approximately 9.5 percent as the basis to determine the discount rate to apply to the estimated future cash flows. In 2012, due to market conditions, the Company increased the discount rate to a range of 11 percent to 13 percent for most of its reporting units. The Company records an impairment to goodwill (adjusting the value to the estimated fair value) if the book value exceeds the estimated fair value.

The Company reviews its other indefinite-lived intangible assets for impairment annually in the fourth quarter of each year, or as events occur or circumstances change that indicate the assets may be impaired without regard to the reporting unit. The Company considers the implications of both external (e.g., market growth, competition and local economic conditions) and internal (e.g., product sales and expected product growth) factors and their potential impact on cash flows related to the intangible asset in both the near- and long-term.

Intangible assets with finite useful lives are amortized using the straight-line method over their estimated useful lives. The Company evaluates the remaining useful lives of amortizable intangible assets at each reporting period to determine whether events and circumstances warrant a revision to the remaining periods of amortization. See Note H for additional information regarding Goodwill and Other Intangible Assets.

Fair Value Accounting. The Company follows accounting guidance for its financial investments and liabilities which defines fair value, establishes a framework for measuring fair value and prescribes disclosures about fair value measurements. The Company also follows this guidance for its non-financial investments and liabilities.

The fair value of financial investments and liabilities is determined at each balance sheet date and future declines in market conditions, the future performance of the underlying investments or new information could affect the recorded values of the Company’s investments in marketable securities, private equity funds and other private investments.

The Company uses derivative financial instruments to manage certain exposure to fluctuations in earnings and cash flows resulting from changes in foreign currency exchange rates, commodity costs and interest rate exposures. Derivative financial instruments are recorded in the consolidated balance sheets as either an asset or liability measured at fair value. For each derivative financial instrument that is designated and qualifies as a fair-value hedge, the gain or loss on the derivative instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in determining current earnings during the period of the change in fair values. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in determining current earnings during the period of the change in fair value.

A. ACCOUNTING POLICIES (Continued)

Warranty. At the time of sale, the Company accrues a warranty liability for the estimated cost to provide products, parts or services to repair or replace products in satisfaction of warranty obligations. The Company’s estimate of costs to service its warranty obligations is based upon the information available and includes a number of factors such as the warranty coverage, the warranty period, historical experience specific to the nature, frequency and average cost to service the claim, along with product manufacturing metrics and industry and demographic trends.

Certain factors and related assumptions in determining our warranty liability involve judgments and estimates and are sensitive to changes in the aforementioned factors. The Company believes that the warranty accrual is appropriate; however, actual claims incurred could differ from the original estimates thereby requiring adjustments to previously established accruals.

A majority of the Company’s business is at the consumer retail level through home centers and major retailers. A consumer may return a product to a retail outlet that is a warranty return. However, certain retail outlets do not distinguish between warranty and other types of returns when they claim a return deduction from the Company. The Company’s revenue recognition policy takes into account this type of return when recognizing revenue, and deductions are recorded at the time of sale.

Product Liability. The Company provides for expenses associated with product liability obligations when such amounts are probable and can be reasonably estimated. The accruals are adjusted as new information develops or circumstances change that would affect the estimated liability.

Stock-Based Compensation. The Company measures compensation expense for stock awards at the market price of the Company’s common stock at the grant date. Effective January 1, 2006, such expense is being recognized ratably over the shorter of the vesting period of the stock awards, typically 5 to 10 years (except for stock awards held by grantees age 66 or older, which vest over five years), or the length of time until the grantee becomes retirement-eligible at age 65. For stock awards granted prior to January 1, 2006, such expense is being recognized over the vesting period of the stock awards, typically 10 years, or for executive grantees that are, or will become, retirement-eligible during the vesting period, the expense is being recognized over five years or immediately upon a grantee’s retirement.

The Company measures compensation expense for stock options using a Black-Scholes option pricing model. Such expense is being recognized ratably over the shorter of the vesting period of the stock options, typically five years, or the length of time until the grantee becomes retirement-eligible at age 65. The Company utilizes the shortcut method to determine the tax windfall pool associated with stock options.

Noncontrolling Interest. The Company owns 68 percent of Hansgrohe AG at both December 31, 2012 and 2011. The aggregate noncontrolling interest, net of dividends, at December 31, 2012 and 2011 has been recorded as a component of equity on the Company’s consolidated balance sheets.

Interest and Penalties on Uncertain Tax Positions. The Company records interest and penalties on its uncertain tax positions in income tax expense.

Reclassifications. Certain prior-year amounts have been reclassified to conform to the 2012 presentation in the consolidated financial statements. In the Company’s consolidated statements of cash flows, the cash flows from discontinued operations are not separately classified.

Recently Issued Accounting Pronouncements. On January 1, 2012, the Company adopted new accounting guidance requiring more prominent presentation of other comprehensive income items in the Company’s consolidated financial statements. The adoption of this new guidance did not have an impact on the Company’s financial position or its results of operations.

B. DISCONTINUED OPERATIONS

The presentation of discontinued operations includes components of the Company that the Company intends to sell, which comprises operations and cash flows that can be clearly distinguished from the rest of the Company.

In early February 2013, the Company determined that its Danish ready-to-assemble cabinet business was no longer core to its long-term growth strategy and, accordingly the Company embarked on a plan for disposition. The disposition is expected to be completed within the next 12 months.

During 2011, the Company determined that several businesses in the Installation and Other Services segment were not core to the Company’s long-term growth strategy. These businesses provide commercial drywall installation, millwork and framing services. During 2012, the Company disposed all of these businesses for net proceeds of $7 million.

The Company has accounted for the business units identified in 2013 and 2011 as discontinued operations. Losses from these discontinued operations were included in loss from discontinued operations, net, in the consolidated statements of operations.

Selected financial information for the discontinued operations during the period owned by the Company, were as follows, in millions:

	2012			2011			2010
Net sales	$	321		$	389		$	409
Operating loss from discontinued operations	$	(44	)	$	(58	)	$	(9	)

Income tax expense (benefit)		8			(10	)		(16	)
Loss from discontinued operations, net	$	(61	)	$	(181	)	$	(16	)

Included in the impairment of assets held for sale, net in 2011 is the impairment of indefinite and definite-lived intangible assets of $56 million, the impairment of goodwill of $57 million and the impairment of fixed and other assets of $17 million. Included in the loss on disposal of discontinued operations, net in 2011 is $3 million expense reflecting the adjustment of certain assets related to businesses disposed in prior years.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

B. DISCONTINUED OPERATIONS (Concluded)

The unusual relationship between income tax expense and loss before income tax in 2012 results primarily from the increase in the deferred tax liability associated with the abandonment of tax basis in indefinite-lived intangibles due to the disposition of certain discontinued operations.

The unusual relationship between income taxes and loss before income taxes in 2011 resulted primarily from certain losses providing no current tax benefit.

The income tax benefit recorded in 2010 relates primarily to the allocation of an income tax benefit to impairment charges on goodwill and other indefinite-lived intangible assets of certain discontinued operations.

The following balance sheet items have been classified as held for sale:

	December 31,
	2012		2011
Receivables	$	32	$	56
Inventories		66		66
Prepaid expenses and other		2		2
Property and equipment, net		103		118
Total assets	$	203	$	242
Accounts payable		31		47
Accrued liabilities		14		20
Deferred income taxes		4		12
Total liabilities	$	49	$	79

In the fourth quarter of 2012, the Company determined that the estimated fair value calculated for this business unit was lower than the net book value. The Company assessed the long-lived assets associated with this business unit and determined that no impairment was necessary at December 31, 2012.

Also during 2011, the Company decided to exit a product line in builders’ hardware in the Decorative Architectural Products segment with net sales of $1 million and an operating loss of $15 million in 2011 (including $8 million to write-down inventory related to satisfaction of contractual obligations). In the first quarter of 2012, the Company disposed of this product line. This business was included in continuing operations through the date of disposal.

C. ACQUISITIONS

In late 2011, the Company acquired a small manufacturer of hot tubs in the Plumbing Products segment; this business allows the Company to expand its spa offering into additional price point categories. The total net cash purchase price was $10 million in 2011. The results of this acquisition are included in the consolidated financial statements from the date of acquisition.

Certain purchase agreements provided for the payment of additional consideration in cash, contingent upon whether certain conditions are met, including the operating performance of the acquired business. At December 31, 2012 and 2011, there was no outstanding contingent consideration.

E. FAIR VALUE OF FINANCIAL INVESTMENTS AND LIABILITIES

Accounting Policy. The Company follows accounting guidance that defines fair value, establishes a framework for measuring fair value and prescribes disclosures about fair value measurements for its financial investments and liabilities. The guidance defines fair value as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Further, it defines a fair value hierarchy, as follows: Level 1 inputs as quoted prices in active markets for identical assets or liabilities; Level 2 inputs as observable inputs other than Level 1 prices, such as quoted market prices for similar assets or liabilities or other inputs that are observable or can be corroborated by market data; and Level 3 inputs as unobservable inputs that are supported by little or no market activity and that are financial instruments whose value is determined using pricing models or instruments for which the determination of fair value requires significant management judgment or estimation.

Financial investments that are available to be traded on readily accessible stock exchanges (domestic or foreign) are considered to have active markets and have been valued using Level 1 inputs. Financial investments that are not available to be traded on a public market or have limited secondary markets, or contain provisions that limit the ability to sell the investment are considered to have inactive markets and have been valued using Level 2 or 3 inputs. The Company incorporated credit risk into the valuations of financial investments by estimating the likelihood of non-performance by the counterparty to the applicable transactions. The estimate included the length of time relative to the contract, financial condition of the counterparty and current market conditions. The criteria for determining if a market was active or inactive were based on the individual facts and circumstances.

Financial Investments. The Company has maintained investments in available-for-sale securities and a number of private equity funds and other private investments, principally as part of its tax planning strategies, as any gains enhance the utilization of any current and future tax capital losses.

Financial investments included in other assets were as follows, in millions:

The Company’s investments in available-for-sale securities at December 31, 2012 and 2011 were as follows, in millions:

			Pre-tax
	Cost Basis		Unrealized Gains		Unrealized Losses		Recorded Basis
December 31, 2012	$	19	$	3	$	—	$	22
December 31, 2011	$	19	$	3	$	—	$	22

The Company’s investments in private equity funds and other private investments are carried at cost. At December 31, 2012, the Company has investments in 15 venture capital funds, with an aggregate carrying value of $16 million. The venture capital funds invest in start-up or smaller, early-stage established businesses, principally in the information technology, bio-technology and health care sectors. At December 31, 2012, the Company also has investments in 21 buyout funds, with an aggregate carrying value of $53 million. The buyout funds invest in later-stage, established businesses and no buyout fund has a concentration in a particular sector.

Recurring Fair Value Measurements. For financial investments measured at fair value on a recurring basis at each reporting period, the unrealized gains or losses (that are deemed to be temporary) are recognized, net of tax effect, through shareholders’ equity, as a component of other comprehensive income. Realized gains and losses and charges for other-than-temporary impairments are included in determining net income, with related purchase costs based upon specific identification.

For marketable securities, the Company reviews, on a recurring basis, industry analyst reports, key ratios and statistics, market analyses and other factors for each investment to determine if an unrealized loss is other-than-temporary.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

E. FAIR VALUE OF FINANCIAL INVESTMENTS AND LIABILITIES (Continued)

In the past, the Company invested excess cash in auction rate securities. Auction rate securities are investment securities that have interest rates which are reset every 7, 28 or 35 days. The fair values of the auction rate securities held by the Company have been estimated, on a recurring basis, using a discounted cash flow model (Level 3 input). The significant inputs in the discounted cash flow model used to value the auction rate securities include: expected maturity of auction rate securities, discount rate used to determine the present value of expected cash flows and assumptions for credit defaults, since the auction rate securities are backed by credit default swap agreements.

During 2011, the Company sold 1,974,000 shares of its investment in TriMas common stock for cash of $43 million; at December 31, 2012 and 2011, the Company did not own any shares of TriMas common stock.

Financial investments and (liabilities) measured at fair value on a recurring basis at each reporting period and the amounts for each level within the fair value hierarchy were as follows, in millions:

E. FAIR VALUE OF FINANCIAL INVESTMENTS AND LIABILITIES (Continued)

Non-Recurring Fair Value Measurements. It is not practicable for the Company to estimate a fair value for private equity funds and other private investments because there are no quoted market prices, and sufficient information is not readily available for the Company to utilize a valuation model to determine the fair value for each fund. These investments are evaluated, on a non-recurring basis, for potential other-than-temporary impairment when impairment indicators are present, or when an event or change in circumstances has occurred, that may have a significant adverse effect on the fair value of the investment.

Impairment indicators the Company considers include the following: whether there has been a significant deterioration in earnings performance, asset quality or business prospects; a significant adverse change in the regulatory, economic or technological environment; a significant adverse change in the general market condition or geographic area in which the investment operates; industry and sector performance; current equity and credit market conditions; and any bona fide offers to purchase the investment for less than the carrying value. The Company also considers specific adverse conditions related to the financial health of and business outlook for the fund, including industry and sector performance. The significant assumptions utilized in analyzing a fund for potential other-than-temporary impairment include current economic conditions, market analysis for specific funds and performance indicators in the residential and commercial construction, bio-technology, health care and information technology sectors in which the applicable funds’ investments operate. Since there is no active trading market for these investments, they are for the most part illiquid. These investments, by their nature, can also have a relatively higher degree of business risk, including financial leverage, than other financial investments. Future changes in market conditions, the future performance of the underlying investments or new information provided by private equity fund managers could affect the recorded values of such investments and the amounts realized upon liquidation. Due to the significant unobservable inputs, the fair value measurements used to evaluate impairment are a Level 3 input.

Financial investments measured at fair value on a non-recurring basis during 2012 and the amounts for each level within the fair value hierarchy were as follows, in millions:

			Fair Value Measurements Using
	Dec. 31, 2012		Quoted Market Prices (Level 1)		Significant Other Observable Unobservable Inputs (Level 2)		Significant Total Inputs (Level 3)		Gains (Losses)
Private equity funds	$	2	$	—	$	—	$	2	$	(2	)

During 2011, there were no financial investments measured on a non-recurring basis. None of the Company’s investments in private equity funds, for which fair value was determined, had unrealized losses in 2012 or 2011.

The remaining private equity investments in 2012 with an aggregate carrying value of $67 million, were not reviewed for impairment, as there were no indicators of impairment or identified events or changes in circumstances that would have a significant adverse effect on the fair value of the investment. The Company did not have any transfers between Level 1 and Level 2 financial assets in 2012 or 2011.

E. FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES (Concluded)

Realized Gains (Losses) and Impairment Charges. During July 2012, based on information from a fund manager, the Company determined that the decline in estimated value of one private equity fund (with an aggregate carrying value of $4 million prior to impairment) was other-than-temporary and, accordingly, recognized non-cash pre-tax impairment charges of $2 million. During 2010, based on information from the fund managers, the Company determined that the decline in the estimated value of three private equity funds (with an aggregate carrying value of $6 million prior to impairment) was other-than-temporary and, accordingly, recognized non-cash, pre-tax impairment charges of $4 million. During 2010, the Company also determined that the decline in the estimated value of one private investment was other-than-temporary and, accordingly, recognized a non-cash, pre-tax impairment charge of $2 million.

Income from financial investments, net, included in other, net, within other income (expense), net, and impairment charges for financial investments were as follows, in millions:

During 2010, the Company and Asahi Tec agreed to amend the preferred stock to include a more favorable conversion feature into common stock and to include a mandatory conversion date of February 28, 2011. As a result of the amendment, the Company recognized a $28 million impairment loss based on the current fair value of the preferred stock on an if-converted basis in 2010. During the last six months of 2010, the Company converted all its holdings of Asahi Tec preferred stock into common stock which was sold, in its entirety, in open market transactions. The Company realized cash proceeds of $11 million and realized losses aggregating $8 million in 2010. As a result of the disposition of the Asahi Tec common stock, the Company received a tax refund of $16 million in 2011 relating to the utilization of a loss carryback to offset taxes paid on prior capital gains.

The impairment charges related to the Company’s financial investments recognized during 2012 and 2010 were based upon then-current estimates for the fair value of certain financial investments; such estimates could change in the near-term based upon future events and circumstances.

The fair value of the Company’s short-term and long-term fixed-rate debt instruments is based principally upon modeled market prices for the same or similar issues or the current rates available to the Company for debt with similar terms and remaining maturities. The aggregate estimated market value of short-term and long-term debt at December 31, 2012 was approximately $4.0 billion, compared with the aggregate carrying value of $3.6 billion. The aggregate estimated market value of short-term and long-term debt at December 31, 2011 was approximately $4.0 billion, compared with the aggregate carrying value of $4.0 billion.

F. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Company is exposed to global market risk as part of its normal daily business activities. To manage these risks, the Company enters into various derivative contracts. These contracts include interest rate swap agreements, foreign currency exchange contracts and contracts intended to hedge the Company’s exposure to copper and zinc. The Company reviews its hedging program, derivative positions and overall risk management on a regular basis.

Interest Rate Swap Agreements. In March 2012, in connection with the issuance of $400 million of debt, the Company terminated the interest rate swap hedge relationships that it had entered into in August 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 approximately $2 million loss was recognized in the Company’s consolidated statement of operations in other, 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 December 31, 2012, the balance remaining was $21 million. At December 31, 2011, the interest rate swaps were considered 100 percent effective; therefore, the market valuation of $23 million was recorded in other comprehensive income in the Company’s statement of shareholders’ equity with a corresponding increase to accrued other in the Company’s condensed consolidated balance sheet at December 31, 2011.

In 2012, the Company recognized a decrease in interest expense of $6 million, offset by interest expense of $2 million related to the cash flow hedge terminated in March 2012. In 2011 and 2010, the Company recognized a decrease in interest expense of $10 million and $12 million, respectively, related to the amortization of gains resulting from the terminations (in 2008 and 2004) of two fair value interest rate swap agreements.

Foreign Currency Contracts. The Company’s 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 during 2012, 2011 and 2010, the Company, including certain European operations, entered into foreign currency forward contracts and foreign currency exchange contracts.

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

Metals Contracts. During 2012, 2011 and 2010, the Company entered into several contracts to manage its exposure to increases in the price of copper and zinc. Gains (losses) related to these contracts are recorded in the Company’s consolidated statements of operations in cost of sales.

The Company leases certain equipment and plant facilities under noncancellable operating leases. Rental expense recorded in the consolidated statements of operations totaled approximately $94 million, $102 million and $110 million during 2012, 2011 and 2010, respectively. Future minimum lease payments at December 31, 2012 were approximately as follows: 2013—$90 million; 2014—$42 million; 2015—$29 million; 2016—$20 million; 2017—$13 million; and 2018 and beyond—$62 million.

The Company leases operating facilities from certain related parties, primarily former owners (and in certain cases, current management personnel) of companies acquired. The Company recorded rental expense to such related parties of approximately $5 million, $5 million and $6 million in 2012, 2011 and 2010, respectively.

As a result of its business rationalization activities over the last several years, at December 31, 2012 and 2011, the Company was holding several facilities for sale, within the Cabinets and Related Products segment and the Other Specialty Products segment. At December 31, 2012 and 2011, the net book value of those facilities was approximately $14 million and $49 million, respectively, and approximates fair value. Fair value was estimated using a market approach, considering the estimated fair values for the other comparable buildings in the areas where the facilities are located, Level 3 inputs.

In the fourth quarter of 2012, the Company determined that the estimated fair value calculated for one business unit in the Plumbing Products segment was lower than the net book value of that business unit. The Company assessed the long-lived assets associated with that business unit and determined that no impairment was necessary at December 31, 2012.

H. GOODWILL AND OTHER INTANGIBLE ASSETS (Concluded)

In the fourth quarters of 2012 and 2011, the Company completed its annual impairment testing of goodwill and other indefinite-lived intangible assets. The impairment test in 2012 indicated there was no impairment of goodwill for any of the Company’s reporting units.

The impairment test in 2011 indicated that goodwill recorded for certain of the Company’s reporting units was impaired. The Company recognized the non-cash, pre-tax impairment charges, in continuing operations, for goodwill of $442 million ($286 million, after tax) for 2011. In 2011, the pre-tax impairment charge in the Decorative Architectural Products segment relates to the builders’ hardware business and reflects increasing competitive conditions for that business. The pre-tax impairment charge in the Other Specialty Products segment relates to the North American window and door business and reflects the continuing weak level of new home construction activity in the western U.S., the reduced levels of repair and remodel activity and the expectation that recovery in these segments will be modestly slower than anticipated. The Company then assessed the long-lived assets associated with these business units and determined no impairment was necessary at December 31, 2011.

Other indefinite-lived intangible assets were $132 million and $174 million at December 31, 2012 and 2011, respectively, and principally included registered trademarks. In 2012 and 2011, the impairment test indicated that the registered trademark for a North American business unit in the Other Specialty Products segment and the registered trademark for a North American business unit in the Plumbing Products segment (2011 only) were impaired due to changes in the long-term outlook for the business units. The Company recognized non-cash, pre-tax impairment charges for other indefinite-lived intangible assets of $42 million ($27 million, after tax) and $8 million ($5 million, after tax) in 2012 and 2011, respectively. In 2010, the Company recognized non-cash, pre-tax impairment charges for other indefinite-lived intangible assets of $10 million ($6 million after tax) related to the Installation and Other Services segment ($9 million pre-tax) and the Plumbing Products segment ($1 million pre-tax).

The carrying value of the Company’s definite-lived intangible assets was $19 million at December 31, 2012 (net of accumulated amortization of $57 million) and $22 million at December 31, 2011 (net of accumulated amortization of $54 million) and principally included customer relationships and non-compete agreements, with a weighted average amortization period of 6 years in both 2012 and 2011. Amortization expense related to the definite-lived intangible assets of continuing operations was $6 million in each of 2012, 2011 and 2010.

At December 31, 2012, amortization expense related to the definite-lived intangible assets during each of the next five years was as follows: 2013—$5 million; 2014—$4 million; 2015—$4 million; 2016—$2 million; and 2017—$1 million.

K. DEBT (Continued)

All of the notes and debentures above are senior indebtedness and, other than the 6.625% notes due 2018 and the 7.75% notes due 2029, are redeemable at the Company’s option.

On March 5, 2012, the Company issued $400 million of 5.95% Notes (“the Notes”) due March 15, 2022. Including the interest rate swap amortization, the effective interest rate for the Notes is approximately 6.5%, see Note F. The Notes are senior indebtedness and are redeemable at the Company’s option.

In January 2012, the Company repurchased $46 million of 5.875% Notes due July 15, 2012 in open-market transactions; the Company paid a premium of $1 million for the repurchase. In July 2012, the Company retired all of its $745 million of 5.875% Notes on the scheduled retirement date.

On June 21, 2010, the Company 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 January 10, 2014. On February 11, 2011, the Company entered into an amendment (deemed to be effective and applicable as of December 31, 2010) of the Credit Agreement with its bank group (the “Amendment”).

On February 13, 2012, the Company entered into another amendment (deemed to be effective and applicable as of December 31, 2011) of the Credit Agreement (the “Second Amendment”). The Credit Agreement contains financial covenants requiring the Company to maintain a maximum debt to total adjusted capitalization ratio of 65 percent. The Second Amendment provides for the add-back to shareholders’ equity in the Company’s debt to capitalization covenant of (i) certain non-cash charges (including impairment charges for financial investments and goodwill and other intangible assets) and (ii) changes to the valuation allowance on the Company’s deferred tax assets included in income tax expense. The Second Amendment also permits the Company to add back, if incurred, up to $250 million in the aggregate of future non-cash charges subsequent to December 31, 2011. The Second Amendment revised the permitted ratio of consolidated EBITDA to consolidated interest expense to 2.25 to 1.00 through December 31, 2012, increasing to 2.50 to 1.00 with respect to each quarter thereafter.

The Credit Agreement provides for an unsecured revolving credit facility available to the Company and one of its 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. The Company can also borrow swingline loans up to $150 million and obtain Letters of Credit of up to $250 million. Any outstanding Letters of Credit reduce the Company’s borrowing capacity. At December 31, 2012, the Company had $78 million of outstanding and unused Letters of Credit, reducing the Company’s borrowing capacity by such amount.

Revolving credit loans bear interest under the Credit Agreement, at the Company’s option: at (A) a rate per annum equal to the greatest of (i) 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 the then-applicable corporate credit ratings of the Company; or (B) LIBOR plus an applicable margin based upon the then-applicable corporate credit ratings of the Company. The foreign currency revolving credit loans bear interest at a rate equal to LIBOR plus an applicable margin based upon the then-applicable corporate credit ratings of the Company.

K. DEBT (Concluded)

Based on the limitations of the debt to total capitalization covenant, at December 31, 2012 the Company had additional borrowing capacity, subject to availability, of up to $873 million. Additionally, at December 31, 2012, the Company could absorb a reduction to shareholders’ equity of approximately $470 million and remain in compliance with the debt to total capitalization covenant.

In order to borrow under the Credit Agreement, there must not be any default in the Company’s covenants in the 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 the Company’s representations and warranties in the 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, 2009, in each case, no material ERISA or environmental non-compliance and no material tax deficiency).

At December 31, 2012 and 2011, the Company was in compliance with all covenants and had no borrowings under the Credit Agreement.

At December 31, 2012, the debt maturities during each of the next five years were as follows: 2013—$206 million; 2014—$1 million; 2015—$501 million; 2016—$1,001 million; and 2017—$301 million.

Interest paid was $269 million, $254 million and $241 million in 2012, 2011 and 2010, respectively.

L. STOCK-BASED COMPENSATION

The Company’s 2005 Long Term Stock Incentive Plan (the “2005 Plan”) provides for the issuance of stock-based incentives in various forms to employees and non-employee Directors of the Company. At December 31, 2012, outstanding stock-based incentives were in the form of long-term stock awards, stock options, phantom stock awards and stock appreciation rights.

L. STOCK-BASED COMPENSATION (Continued)

Long-Term Stock Awards. Long-term stock awards are granted to key employees and non-employee Directors of the Company and do not cause net share dilution inasmuch as the Company continues the practice of repurchasing and retiring an equal number of shares on the open market.

At December 31, 2012, 2011 and 2010, there was $72 million, $107 million and $127 million, respectively, of unrecognized compensation expense related to unvested stock awards; such awards had a weighted average remaining vesting period of four years for 2012, four years for 2011 and five years for 2010.

The total market value (at the vesting date) of stock award shares which vested during 2012, 2011 and 2010 was $27 million, $28 million and $22 million, respectively.

Stock Options. Stock options are granted to key employees of the Company. The exercise price equals the market price of the Company’s 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. The 2005 Plan does not permit the granting of restoration stock options, except for restoration options resulting from options previously granted under the 1991 Plan. Restoration stock options become exercisable six months from the date of grant.

The Company granted 1,080,750 of stock option shares, including restoration stock option shares, during 2012 with a grant date exercise price of approximately $12 per share. During 2012, 5,894,710 stock option shares were forfeited (including options that expired unexercised).

Phantom Stock Awards and Stock Appreciation Rights (“SARs”). The Company grants phantom stock awards and SARs to certain non-U.S. employees.

Phantom stock awards are linked to the value of the Company’s common stock on the date of grant and are settled in cash upon vesting, typically over 5 to 10 years. The Company accounts for phantom stock awards as liability-based awards; the compensation expense is initially measured as the market price of the Company’s common stock at the grant date and is recognized over the vesting period. The liability is remeasured and adjusted at the end of each reporting period until the awards are fully-vested and paid to the employees. The Company recognized expense of $7 million, $2 million and $2 million related to the valuation of phantom stock awards for 2012, 2011 and 2010, respectively. In 2012, 2011 and 2010, the Company granted 162,310 shares, 349,550 shares and 299,650 shares, respectively, of phantom stock awards with an aggregate fair value of $2 million, $4 million and $4 million, respectively, and paid $3 million, $2 million and $1 million of cash in 2012, 2011 and 2010, respectively, to settle phantom stock awards.

SARs are linked to the value of the Company’s common stock on the date of grant and are settled in cash upon exercise. The Company accounts for SARs using the fair value method, which requires outstanding SARs to be classified as liability-based awards and valued using a Black-Scholes option pricing model at the grant date; such fair value is recognized as compensation expense over the vesting period, typically five years. The liability is remeasured and adjusted at the end of each reporting period until the SARs are exercised and payment is made to the employees or the SARs expire. The Company recognized expense (income) of $4 million, $(1) million and $1 million related to the valuation of SARs for 2012, 2011 and 2010, respectively. During 2012 and 2011, the Company did not grant any SARs. During 2010, the Company granted SARs for 429,300 shares, with an aggregate fair value of $2 million in 2010.

M. EMPLOYEE RETIREMENT PLANS

The Company sponsors qualified defined-benefit and defined-contribution retirement plans for most of its employees. In addition to the Company’s qualified defined-benefit pension plans, the Company has unfunded non-qualified defined-benefit pension plans covering certain employees, which provide for benefits in addition to those provided by the qualified pension plans. Substantially all salaried employees participate in non-contributory defined-contribution retirement plans, to which payments are determined annually by the Organization and Compensation Committee of the Board of Directors. Aggregate charges to earnings under the Company’s defined-benefit and defined-contribution retirement plans were $36 million and $43 million in 2012, $34 million and $31 million in 2011 and $34 million and $47 million in 2010, respectively.

In addition, the Company participates in 20 regional multi-employer pension plans, principally related to building trades; none of the plans are considered significant. The aggregate expense recognized through contributions by the Company to these plans was approximately $4 million, $3 million and $3 million in 2012, 2011 and 2010, respectively.

In March 2009, based on management’s recommendation, the Board of Directors approved a plan to freeze all future benefit accruals under substantially all of the Company’s domestic qualified and non-qualified defined-benefit pension plans. The freeze was effective January 1, 2010.

Plan Assets. The Company’s qualified defined-benefit pension plan weighted average asset allocation, which is based upon fair value, was as follows:

	At December 31
	2012			2011
Equity securities		44	%		44	%
Debt securities		41	%		39	%

Plan assets included 600,000 and 1.2 million shares of Company common stock valued at $10 million and $12 million at December 31, 2012 and 2011, respectively.

The Company’s qualified defined-benefit pension plans have adopted accounting guidance that defines fair value, establishes a framework for measuring fair value and prescribes disclosures about fair value measurements. Accounting guidance defines fair value as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.”

M. EMPLOYEE RETIREMENT PLANS (Continued)

Following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2012.

Common and Preferred Stocks and Short-Term and Other Investments: Valued at the closing price reported on the active market on which the individual securities are traded, or based on the active market for similar securities. For certain Short-Term and Other Investments, there is no active trading market and they are for the most part illiquid. Due to the significant unobservable inputs, the fair value measurements used to estimate fair value are Level 3 inputs.

Private Equity Funds: Valued based on an estimated fair value using either a market approach or an income approach, each of which requires a significant degree of judgment. There is no active trading market for these investments and they are for the most part illiquid. Due to the significant unobservable inputs, the fair value measurements used to estimate fair value are a Level 3 input.

Corporate Debt Securities: Valued based on the active market for similar securities or on estimated fair value.

Government and Other Debt Securities: Valued based on either the closing price reported on the active market on which the individual securities are traded, the market for similar securities or estimated fair value based on a model for similar securities.

Common Collective Trust Fund: Valued based on a unit value basis, which approximates fair value as of December 31, 2012 and 2011, respectively. Such basis is determined by reference to the respective fund’s underlying assets, which are primarily marketable equity and fixed income securities. There are no unfunded commitments or other restrictions associated with this fund.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Assumptions. Major assumptions used in accounting for the Company’s defined-benefit pension plans were as follows:

December 31

	December 31
	2012			2011			2010
Discount rate for obligations		3.80	%		4.40	%		5.30	%
Expected return on plan assets		7.25	%		7.25	%		7.25	%
Rate of compensation increase		—	%		—	%		1.00	%
Discount rate for net periodic pension cost		4.40	%		5.30	%		5.80	%

The discount rate for obligations for 2012 and 2011 was based upon the expected duration of each defined-benefit pension plan’s liabilities matched to the December 31, 2012 and 2011 Towers Watson Rate Link Curve. At December 31, 2012, such rates for the Company’s defined-benefit pension plans ranged from 1.75 percent to 4.50 percent, with the most significant portion of the liabilities having a discount rate for obligations of 3.40 percent or higher. At December 31, 2011, such rates for the Company’s defined-benefit pension plans ranged from 2.00 percent to 5.50 percent, with the most significant portion of the liabilities having a discount rate for obligations of 4.20 percent or higher. The decline in the weighted average discount rate over the last several years is principally the result of lower long-term interest rates in the bond markets. The weighted average discount rates were also affected by the freezing of all future benefit accruals for substantially all of the Company’s domestic qualified and non-qualified defined-benefit plans, which shortened the period of future payments.

For 2012 and 2011, the Company determined the expected long-term rate of return on plan assets of 7.25 percent based upon an analysis of expected and historical rates of return of various asset classes utilizing the current and long-term target asset allocation of the plan assets. The projected asset return at both December 31, 2012 and 2011 also considered near term returns, including current market conditions and also that pension assets are long-term in nature. The actual annual rate of return on the Company’s pension plan assets was 6.9 percent and 3.2 percent for the 10-year periods ended December 31, 2012 and 2011, respectively. Although these rates of return are less than the Company’s current expected long-term rate of return on plan assets, the Company notes that the 10-year period ended December 31, 2012 includes one significant decline in the equity markets. In 2012, actual annual rate of return on the Company’s pension plan assets was 17 percent. Accordingly, the Company believes a 7.25 percent expected long-term rate of return is reasonable.

M. EMPLOYEE RETIREMENT PLANS (Continued)

The investment objectives seek to minimize the volatility of the value of the Company’s plan assets relative to pension liabilities and to ensure plan assets are sufficient to pay plan benefits. In 2012 and 2011, the Company achieved its targeted asset allocation: 45 percent equities, 25 percent fixed-income, 15 percent global assets (combination of equity and fixed-income) and 15 percent alternative investments (such as private equity, commodities and hedge funds). The asset allocation of the investment portfolio was developed with the objective of achieving the Company’s expected rate of return and reducing volatility of asset returns, and considered the freezing of future benefits. The equity portfolios are invested in individual securities or funds that are expected to mirror broad market returns for equity securities. The fixed-income portfolio is invested in corporate bonds, bond index funds or U.S. Treasury securities. The increased allocation to fixed-income securities partially matches the bond-like and long-term nature of the pension liabilities. It is expected that the alternative investments would have a higher rate of return than the targeted overall long-term return of 7.25 percent. However, these investments are subject to greater volatility, due to their nature, than a portfolio of equities and fixed-income investments, and would be less liquid than financial instruments that trade on public markets. This portfolio is expected to yield a long-term rate of return of 7.25 percent.

The fair value of the Company’s plan assets is subject to risk including significant concentrations of risk in the Company’s plan assets related to equity, interest rate and operating risk. In order to ensure plan assets are sufficient to pay benefits, a portion of plan assets is allocated to equity investments that are expected, over time, to earn higher returns with more volatility than fixed-income investments which more closely match pension liabilities. Within equity, risk is mitigated by targeting a portfolio that is broadly diversified by geography, market capitalization, manager mandate size, investment style and process.

In order to minimize asset volatility relative to the liabilities, a portion of plan assets are allocated to fixed-income investments that are exposed to interest rate risk. Rate increases generally will result in a decline in fixed-income assets, while reducing the present value of the liabilities. Conversely, rate decreases will increase fixed income assets, partially offsetting the related increase in the liabilities.

Potential events or circumstances that could have a negative effect on estimated fair value include the risks of inadequate diversification and other operating risks. To mitigate these risks, investments are diversified across and within asset classes in support of investment objectives. Policies and practices to address operating risks include ongoing manager oversight, plan and asset class investment guidelines and instructions that are communicated to managers, and periodic compliance and audit reviews to ensure adherence to these policies. In addition, the Company periodically seeks the input of its independent advisor to ensure the investment policy is appropriate.

Other. The Company sponsors certain post-retirement benefit plans that provide medical, dental and life insurance coverage for eligible retirees and dependents in the United States based upon age and length of service. The aggregate present value of the unfunded accumulated post-retirement benefit obligation was $12 million and $14 million at December 31, 2012 and 2011, respectively.

N. SHAREHOLDERS’ EQUITY

In July 2007, the Company’s Board of Directors authorized the repurchase for retirement of up to 50 million shares of the Company’s common stock in open-market transactions or otherwise. At December 31, 2012, the Company had remaining authorization to repurchase up to 24 million shares. During 2012, the Company repurchased and retired one million shares of Company common stock, for cash aggregating $8 million to offset the dilutive impact of the 2012 grant of one million shares of long-term stock awards. The Company repurchased and retired two million common shares in 2011 and three million common shares in 2010 for cash aggregating $30 million and $45 million in 2011 and 2010, respectively.

On the basis of amounts paid (declared), cash dividends per common share were $.30 ($.30) in 2012, $.30 ($.30) in 2011 and $.30 ($.30) in 2010, respectively.

The current portion of the state and local income tax benefit includes a $14 million and $10 million tax benefit from the reversal of an accrual for uncertain tax positions resulting primarily from the expiration of applicable statutes of limitations and favorable settlements on state audits in 2012 and 2011, respectively. The deferred portion of the state and local taxes includes a $26 million and $31 million non-cash charge to income tax expense resulting from a change in the valuation allowance against state and local deferred tax assets in 2012 and 2011, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

R. INCOME TAXES (Continued)

The accounting guidance for income taxes requires that the future realization of deferred tax assets depends on the existence of sufficient taxable income in future periods. Possible sources of taxable income include taxable income in carryback periods, the future reversal of existing taxable temporary differences recorded as a deferred tax liability, tax-planning strategies that generate future income or gains in excess of anticipated losses in the carryforward period and projected future taxable income.

If, based upon all available evidence, both positive and negative, it is more likely than not (more than 50 percent likely) such deferred tax assets will not be realized, a valuation allowance is recorded. Significant weight is given to positive and negative evidence that is objectively verifiable. A company’s three-year cumulative loss position is significant negative evidence in considering whether deferred tax assets are realizable and the accounting guidance restricts the amount of reliance the Company can place on projected taxable income to support the recovery of the deferred tax assets.

In the fourth quarter of 2010, the Company recorded a $372 million valuation allowance against its U.S. Federal deferred tax assets as a non-cash charge to income tax expense. In reaching this conclusion, the Company considered the weaker retail sales of certain of its building products and the slower than anticipated recovery in the U.S. housing market which led to U.S. operating losses and significant U.S. goodwill impairment charges, that primarily occurred in the fourth quarter of 2010, causing the Company to be in a three-year cumulative U.S. loss position.

During 2012 and 2011, objective and verifiable negative evidence, such as U.S. operating losses and significant impairment charges for U.S. goodwill in 2011 and other intangible assets, continued to outweigh positive evidence necessary to reduce the valuation allowance. As a result, the Company recorded increases of $65 million and $89 million in the valuation allowance against its U.S. Federal deferred tax assets as a non-cash charge to income tax expense in 2012 and 2011, respectively.

Recording the valuation allowance does not restrict the Company’s ability to utilize the future deductions and net operating losses associated with the deferred tax assets assuming taxable income is recognized in future periods.

A rebound in the U.S. housing market from the recent historic lows and retail sales of building products improving from their current levels should have a positive impact on the Company’s operating results in the U.S. A return to sustained profitability in the U.S. should result in objective positive evidence thereby warranting the potential reversal of all or a portion of the valuation allowance.

The $203 million and $156 million of deferred tax assets at December 31, 2012 and 2011, respectively, for which there is no valuation allowance recorded, is anticipated to be realized through the future reversal of existing taxable temporary differences recorded as deferred tax liabilities.

Of the deferred tax asset related to the net operating loss and tax credit carryforwards at December 31, 2012 $411 million will expire between 2020 and 2032 and $14 million is unlimited. Of the deferred tax asset related to the net operating loss and tax credit carryforwards at December 31, 2011 $269 million will expire between 2020 and 2031 and $11 million is unlimited.

The tax benefit from certain stock-based compensation is not recognized as a deferred tax asset until the tax deduction reduces cash taxes. Accordingly, as of December 31, 2012, the Company has not recorded a $27 million deferred tax asset on additional net operating losses that, when realized, will be recorded to paid-in capital.

A tax provision has not been provided at December 31, 2012 for U.S. income taxes or additional foreign withholding taxes on approximately $10 million of undistributed earnings of certain foreign subsidiaries that are considered to be permanently reinvested. It is not practicable to determine the amount of deferred tax liability on such earnings as the actual U.S. tax would depend on income tax laws and circumstances at the time of distribution.

A reconciliation of the U.S. Federal statutory tax rate to the income tax expense (benefit) on income (loss) from continuing operations was as follows:

	2012			2011			2010
U.S. Federal statutory tax rate – expense (benefit)		35	%		(35	%)		(35	%)
State and local taxes, net of U.S. Federal tax benefit		4			—			1

If recognized, $34 million and $40 million of the liability for uncertain tax positions at December 31, 2012 and 2011, respectively, net of any U.S. Federal tax benefit, would impact the Company’s effective tax rate.

At December 31, 2012 and 2011, $74 and $86 million of the total liability for uncertain tax positions, including related interest and penalties, is recorded in deferred income taxes and other, $1 and $1 million is recorded in accrued liabilities and $7 and $6 million is recorded in other assets, respectively.

The Company files income tax returns in the U.S. Federal jurisdiction, and various local, state and foreign jurisdictions. The Company continues to participate in the Compliance Assurance Program (“CAP”). CAP is a real-time audit of the U.S. Federal income tax return that allows the Internal Revenue Service (“IRS”), working in conjunction with the Company, to determine tax return compliance with the U.S. Federal tax law prior to filing the return. This program provides the Company with greater certainty about its tax liability for a given year within months, rather than years, of filing its annual tax return and greatly reduces the need for recording a liability for U.S. Federal uncertain tax positions. The IRS has completed their examination of the Company’s consolidated U.S. Federal tax returns through 2011. With few exceptions, the Company is no longer subject to state or foreign income tax examinations on filed returns for years before 2000.

As a result of tax audit closings, settlements and the expiration of applicable statutes of limitations in various jurisdictions within the next 12 months, the Company anticipates that it is reasonably possible the liability for uncertain tax positions could be reduced by approximately $6 million.

The Company follows accounting guidance regarding determining whether instruments granted in share-based payment transactions are participating securities. This accounting guidance clarifies that share-based payment awards that entitle their holders to receive non-forfeitable dividends prior to vesting should be considered participating securities. The Company has granted restricted stock awards that contain non-forfeitable rights to dividends on unvested shares; such unvested restricted stock awards are considered participating securities. As participating securities, the unvested shares are required to be included in the calculation of the Company’s basic earnings per common share, using the “two-class method.” The two-class method of computing earnings per common share is an allocation method that calculates earnings per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. For the years ended December 31, 2012, 2011 and 2010, the Company allocated dividends to the unvested restricted stock awards (participating securities).

At December 31, 2011 and 2010, the Company did not include any common shares related to the Zero Coupon Convertible Senior Notes (“Notes”) in the calculation of diluted earnings per common share, as the price of the Company’s common stock at December 31, 2010 did not exceed the equivalent accreted value of the Notes.

Additionally, 30 million common shares, 36 million common shares and 37 million common shares for 2012, 2011 and 2010, respectively, related to stock options were excluded from the computation of diluted earnings per common share due to their antidilutive effect.

Common shares outstanding included on the Company’s balance sheet and for the calculation of earnings per common share do not include unvested stock awards (8 million shares and 10 million common shares at December 31, 2012 and 2011, respectively); shares outstanding for legal requirements included all common shares that have voting rights (including unvested stock awards).

T. OTHER COMMITMENTS AND CONTINGENCIES

Litigation. We are subject to claims, charges, litigation and other proceedings in the ordinary course of our business, including those arising from or related to contractual matters, intellectual property, personal injury, environmental matters, product liability, construction defect, insurance coverage, personnel and employment disputes and other matters, including class actions. We believe we have adequate defenses in these matters and that the outcome of these matters is not likely to have a material adverse effect on us. 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.

In July 2012, the Company reached a settlement agreement related to the Columbus Drywall litigation. The Company and its insulation installation companies named in the suit agreed to pay $75 million in return for dismissal with prejudice and full release of all claims. The Company and its insulation installation companies continue to deny that the challenged conduct was unlawful and admit no wrongdoing as part of the settlement. A settlement was reached to eliminate the considerable expense and uncertainty of this lawsuit. The Company recorded the settlement expense in the second quarter of 2012 and the amount was paid in the fourth quarter of 2012.

Warranty. At the time of sale, the Company accrues a warranty liability for the estimated cost to provide products, parts or services to repair or replace products in satisfaction of warranty obligations. During the third quarter of 2012, a business in the Other Specialty Products segment recorded a $12 million increase in expected future warranty claims resulting from the completion of an analysis prepared by the Company based upon its periodic assessment of recent business unit specific operating trends including, among others, home ownership demographics, sales volumes, manufacturing quality, an analysis of recent warranty claim activity and an estimate of current costs to service anticipated claims.

Investments. With respect to the Company’s investments in private equity funds, the Company had, at December 31, 2012, commitments to contribute up to $19 million of additional capital to such funds representing the Company’s aggregate capital commitment to such funds less capital contributions made to date. The Company is contractually obligated to make additional capital contributions to certain of its private equity funds upon receipt of a capital call from the private equity fund. The Company has no control over when or if the capital calls will occur. Capital calls are funded in cash and generally result in an increase in the carrying value of the Company’s investment in the private equity fund when paid.

Other Matters. The Company enters into contracts, which include reasonable and customary indemnifications that are standard for the industries in which it operates. Such indemnifications include customer claims against builders for issues relating to the Company’s products and workmanship. In conjunction with divestitures and other transactions, the Company occasionally provides reasonable and customary indemnifications relating to various items including: the enforceability of trademarks; legal and environmental issues; provisions for sales returns; and asset valuations. The Company has never had to pay a material amount related to these indemnifications and evaluates the probability that amounts may be incurred and appropriately records an estimated liability when probable.

Accounting Policies [Abstract]

Accounting Policies

A. ACCOUNTING POLICIES

Principles of Consolidation. The consolidated financial statements include the accounts of Masco Corporation and all majority-owned subsidiaries. All significant intercompany transactions have been eliminated. The Company consolidates the assets, liabilities and results of operations of variable interest entities, for which the Company is the primary beneficiary.

Use of Estimates and Assumptions in the Preparation of Financial Statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of any contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates and assumptions.

Revenue Recognition. The Company recognizes revenue as title to products and risk of loss is transferred to customers or when services are rendered, net of applicable provisions for discounts, returns and allowances. The Company records revenue for unbilled services performed based upon material and labor incurred in the Installation and Other Services segment; such amounts are recorded in Receivables. Amounts billed for shipping and handling are included in net sales, while costs incurred for shipping and handling are included in cost of sales.

Customer Promotion Costs. The Company records estimated reductions to revenue for customer programs and incentive offerings, including special pricing and co-operative advertising arrangements, promotions and other volume-based incentives. In-store displays that are owned by the Company and used to market the Company’s products are included in other assets in the consolidated balance sheets and are amortized using the straight-line method over the expected useful life of three to five years; related amortization expense is classified as a selling expense in the consolidated statements of operations.

Foreign Currency. The financial statements of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities of these subsidiaries are translated at exchange rates as of the balance sheet date. Revenues and expenses are translated at average exchange rates in effect during the year. The resulting cumulative translation adjustments have been recorded in the accumulated other comprehensive income component of shareholders’ equity. Realized foreign currency transaction gains and losses are included in the consolidated statements of operations in other income (expense), net.

Cash and Cash Investments. The Company considers all highly liquid investments with an initial maturity of three months or less to be cash and cash investments.

Receivables. The Company does significant business with a number of customers, including certain home centers and homebuilders. The Company monitors its exposure for credit losses on its customer receivable balances and the credit worthiness of its customers on an on-going basis and records related allowances for doubtful accounts. Allowances are estimated based upon specific customer balances, where a risk of default has been identified, and also include a provision for non-customer specific defaults based upon historical collection, return and write-off activity. During downturns in the Company’s markets, declines in the financial condition and creditworthiness of customers impacts the credit risk of the receivables involved and the Company has incurred additional bad debt expense related to customer defaults. A separate allowance is recorded for customer incentive rebates and is generally based upon sales activity. Receivables are presented net of certain allowances (including allowances for doubtful accounts) of $71 million and $59 million at December 31, 2012 and 2011, respectively. Receivables include unbilled revenue related to the Installation and Other Services segment of $18 million and $17 million at December 31, 2012 and 2011, respectively.

Property and Equipment. Property and equipment, including significant betterments to existing facilities, are recorded at cost. Upon retirement or disposal, the cost and accumulated depreciation are removed from the accounts and any gain or loss is included in the consolidated statements of operations. Maintenance and repair costs are charged against earnings as incurred.

The Company reviews its property and equipment as an event occurs or circumstances change that would more likely than not reduce the fair value of the property and equipment below the carrying amount. If the carrying amount of property and equipment is not recoverable from its undiscounted cash flows, then the Company would recognize an impairment loss for the difference between the carrying amount and the current fair value. Further, the Company evaluates the remaining useful lives of property and equipment at each reporting period to determine whether events and circumstances warrant a revision to the remaining depreciation periods.

Depreciation. Depreciation expense is computed principally using the straight-line method over the estimated useful lives of the assets. Annual depreciation rates are as follows: buildings and land improvements, 2 to 10 percent, and machinery and equipment, 5 to 33 percent. Depreciation expense was $192 million, $234 million and $249 million in 2012, 2011 and 2010, respectively. Such depreciation expense included accelerated depreciation of $28 million (primarily in the Cabinets and Related Products and Plumbing Products segments), $52 million (primarily in the Cabinets and Related Products and Other Specialty Products segments) and $43 million (primarily in the Cabinets and Related Products segment) in 2012, 2011 and 2010, respectively.

Goodwill and Other Intangible Assets. The Company performs its annual impairment testing of goodwill in the fourth quarter of each year, or as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company has defined its reporting units and completed the impairment testing of goodwill at the operating segment level. The Company’s operating segments are reporting units that engage in business activities, for which discrete financial information, including five-year forecasts, are available. The Company compares the fair value of the reporting units to the carrying value of the reporting units for goodwill impairment testing. Fair value is determined using a discounted cash flow method, which includes significant unobservable inputs (Level 3 inputs).

Determining market values using a discounted cash flow method requires the Company to make significant estimates and assumptions, including long-term projections of cash flows, market conditions and appropriate discount rates. The Company’s judgments are based upon historical experience, current market trends, consultations with external valuation specialists and other information. In estimating future cash flows, the Company relies on internally generated five-year forecasts for sales and operating profits, including capital expenditures, and generally a one to three percent long-term assumed annual growth rate of cash flows for periods after the five-year forecast. The Company utilizes its weighted average cost of capital of approximately 9.5 percent as the basis to determine the discount rate to apply to the estimated future cash flows. In 2012, due to market conditions, the Company increased the discount rate to a range of 11 percent to 13 percent for most of its reporting units. The Company records an impairment to goodwill (adjusting the value to the estimated fair value) if the book value exceeds the estimated fair value.

The Company reviews its other indefinite-lived intangible assets for impairment annually in the fourth quarter of each year, or as events occur or circumstances change that indicate the assets may be impaired without regard to the reporting unit. The Company considers the implications of both external (e.g., market growth, competition and local economic conditions) and internal (e.g., product sales and expected product growth) factors and their potential impact on cash flows related to the intangible asset in both the near- and long-term.

Intangible assets with finite useful lives are amortized using the straight-line method over their estimated useful lives. The Company evaluates the remaining useful lives of amortizable intangible assets at each reporting period to determine whether events and circumstances warrant a revision to the remaining periods of amortization. See Note H for additional information regarding Goodwill and Other Intangible Assets.

Fair Value Accounting. The Company follows accounting guidance for its financial investments and liabilities which defines fair value, establishes a framework for measuring fair value and prescribes disclosures about fair value measurements. The Company also follows this guidance for its non-financial investments and liabilities.

The fair value of financial investments and liabilities is determined at each balance sheet date and future declines in market conditions, the future performance of the underlying investments or new information could affect the recorded values of the Company’s investments in marketable securities, private equity funds and other private investments.

The Company uses derivative financial instruments to manage certain exposure to fluctuations in earnings and cash flows resulting from changes in foreign currency exchange rates, commodity costs and interest rate exposures. Derivative financial instruments are recorded in the consolidated balance sheets as either an asset or liability measured at fair value. For each derivative financial instrument that is designated and qualifies as a fair-value hedge, the gain or loss on the derivative instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in determining current earnings during the period of the change in fair values. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in determining current earnings during the period of the change in fair value.

Warranty. At the time of sale, the Company accrues a warranty liability for the estimated cost to provide products, parts or services to repair or replace products in satisfaction of warranty obligations. The Company’s estimate of costs to service its warranty obligations is based upon the information available and includes a number of factors such as the warranty coverage, the warranty period, historical experience specific to the nature, frequency and average cost to service the claim, along with product manufacturing metrics and industry and demographic trends.

Certain factors and related assumptions in determining our warranty liability involve judgments and estimates and are sensitive to changes in the aforementioned factors. The Company believes that the warranty accrual is appropriate; however, actual claims incurred could differ from the original estimates thereby requiring adjustments to previously established accruals.

A majority of the Company’s business is at the consumer retail level through home centers and major retailers. A consumer may return a product to a retail outlet that is a warranty return. However, certain retail outlets do not distinguish between warranty and other types of returns when they claim a return deduction from the Company. The Company’s revenue recognition policy takes into account this type of return when recognizing revenue, and deductions are recorded at the time of sale.

Product Liability. The Company provides for expenses associated with product liability obligations when such amounts are probable and can be reasonably estimated. The accruals are adjusted as new information develops or circumstances change that would affect the estimated liability.

Stock-Based Compensation. The Company measures compensation expense for stock awards at the market price of the Company’s common stock at the grant date. Effective January 1, 2006, such expense is being recognized ratably over the shorter of the vesting period of the stock awards, typically 5 to 10 years (except for stock awards held by grantees age 66 or older, which vest over five years), or the length of time until the grantee becomes retirement-eligible at age 65. For stock awards granted prior to January 1, 2006, such expense is being recognized over the vesting period of the stock awards, typically 10 years, or for executive grantees that are, or will become, retirement-eligible during the vesting period, the expense is being recognized over five years or immediately upon a grantee’s retirement.

The Company measures compensation expense for stock options using a Black-Scholes option pricing model. Such expense is being recognized ratably over the shorter of the vesting period of the stock options, typically five years, or the length of time until the grantee becomes retirement-eligible at age 65. The Company utilizes the shortcut method to determine the tax windfall pool associated with stock options.

Noncontrolling Interest. The Company owns 68 percent of Hansgrohe AG at both December 31, 2012 and 2011. The aggregate noncontrolling interest, net of dividends, at December 31, 2012 and 2011 has been recorded as a component of equity on the Company’s consolidated balance sheets.

Interest and Penalties on Uncertain Tax Positions. The Company records interest and penalties on its uncertain tax positions in income tax expense.

Reclassifications. Certain prior-year amounts have been reclassified to conform to the 2012 presentation in the consolidated financial statements. In the Company’s consolidated statements of cash flows, the cash flows from discontinued operations are not separately classified.

Recently Issued Accounting Pronouncements. On January 1, 2012, the Company adopted new accounting guidance requiring more prominent presentation of other comprehensive income items in the Company’s consolidated financial statements. The adoption of this new guidance did not have an impact on the Company’s financial position or its results of operations.

Other Commitments and Contingencies

T. OTHER COMMITMENTS AND CONTINGENCIES

Litigation. We are subject to claims, charges, litigation and other proceedings in the ordinary course of our business, including those arising from or related to contractual matters, intellectual property, personal injury, environmental matters, product liability, construction defect, insurance coverage, personnel and employment disputes and other matters, including class actions. We believe we have adequate defenses in these matters and that the outcome of these matters is not likely to have a material adverse effect on us. 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.

In July 2012, the Company reached a settlement agreement related to the Columbus Drywall litigation. The Company and its insulation installation companies named in the suit agreed to pay $75 million in return for dismissal with prejudice and full release of all claims. The Company and its insulation installation companies continue to deny that the challenged conduct was unlawful and admit no wrongdoing as part of the settlement. A settlement was reached to eliminate the considerable expense and uncertainty of this lawsuit. The Company recorded the settlement expense in the second quarter of 2012 and the amount was paid in the fourth quarter of 2012.

Warranty. At the time of sale, the Company accrues a warranty liability for the estimated cost to provide products, parts or services to repair or replace products in satisfaction of warranty obligations. During the third quarter of 2012, a business in the Other Specialty Products segment recorded a $12 million increase in expected future warranty claims resulting from the completion of an analysis prepared by the Company based upon its periodic assessment of recent business unit specific operating trends including, among others, home ownership demographics, sales volumes, manufacturing quality, an analysis of recent warranty claim activity and an estimate of current costs to service anticipated claims.

Changes in the Company’s warranty liability were as follows, in millions:

	2012			2011
Balance at January 1	$	102		$	107
Accruals for warranties issued during the year		42			28
Accruals related to pre-existing warranties		16			8
Settlements made (in cash or kind) during the year		(38	)		(38	)
Other, net (including currency translation)		(4	)		(3	)
Balance at December 31	$	118		$	102

Investments. With respect to the Company’s investments in private equity funds, the Company had, at December 31, 2012, commitments to contribute up to $19 million of additional capital to such funds representing the Company’s aggregate capital commitment to such funds less capital contributions made to date. The Company is contractually obligated to make additional capital contributions to certain of its private equity funds upon receipt of a capital call from the private equity fund. The Company has no control over when or if the capital calls will occur. Capital calls are funded in cash and generally result in an increase in the carrying value of the Company’s investment in the private equity fund when paid.

Other Matters. The Company enters into contracts, which include reasonable and customary indemnifications that are standard for the industries in which it operates. Such indemnifications include customer claims against builders for issues relating to the Company’s products and workmanship. In conjunction with divestitures and other transactions, the Company occasionally provides reasonable and customary indemnifications relating to various items including: the enforceability of trademarks; legal and environmental issues; provisions for sales returns; and asset valuations. The Company has never had to pay a material amount related to these indemnifications and evaluates the probability that amounts may be incurred and appropriately records an estimated liability when probable.

Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2012

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation. The consolidated financial statements include the accounts of Masco Corporation and all majority-owned subsidiaries. All significant intercompany transactions have been eliminated. The Company consolidates the assets, liabilities and results of operations of variable interest entities, for which the Company is the primary beneficiary.

Use of Estimates and Assumptions in the Preparation of Financial Statements

Use of Estimates and Assumptions in the Preparation of Financial Statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of any contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates and assumptions.

Revenue Recognition

Revenue Recognition. The Company recognizes revenue as title to products and risk of loss is transferred to customers or when services are rendered, net of applicable provisions for discounts, returns and allowances. The Company records revenue for unbilled services performed based upon material and labor incurred in the Installation and Other Services segment; such amounts are recorded in Receivables. Amounts billed for shipping and handling are included in net sales, while costs incurred for shipping and handling are included in cost of sales.

Customer Promotion Costs

Customer Promotion Costs. The Company records estimated reductions to revenue for customer programs and incentive offerings, including special pricing and co-operative advertising arrangements, promotions and other volume-based incentives. In-store displays that are owned by the Company and used to market the Company’s products are included in other assets in the consolidated balance sheets and are amortized using the straight-line method over the expected useful life of three to five years; related amortization expense is classified as a selling expense in the consolidated statements of operations.

Foreign Currency

Foreign Currency. The financial statements of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities of these subsidiaries are translated at exchange rates as of the balance sheet date. Revenues and expenses are translated at average exchange rates in effect during the year. The resulting cumulative translation adjustments have been recorded in the accumulated other comprehensive income component of shareholders’ equity. Realized foreign currency transaction gains and losses are included in the consolidated statements of operations in other income (expense), net.

Cash and Cash Investments

Cash and Cash Investments. The Company considers all highly liquid investments with an initial maturity of three months or less to be cash and cash investments.

Receivables

Receivables. The Company does significant business with a number of customers, including certain home centers and homebuilders. The Company monitors its exposure for credit losses on its customer receivable balances and the credit worthiness of its customers on an on-going basis and records related allowances for doubtful accounts. Allowances are estimated based upon specific customer balances, where a risk of default has been identified, and also include a provision for non-customer specific defaults based upon historical collection, return and write-off activity. During downturns in the Company’s markets, declines in the financial condition and creditworthiness of customers impacts the credit risk of the receivables involved and the Company has incurred additional bad debt expense related to customer defaults. A separate allowance is recorded for customer incentive rebates and is generally based upon sales activity. Receivables are presented net of certain allowances (including allowances for doubtful accounts) of $71 million and $59 million at December 31, 2012 and 2011, respectively. Receivables include unbilled revenue related to the Installation and Other Services segment of $18 million and $17 million at December 31, 2012 and 2011, respectively.

Property and Equipment

Property and Equipment. Property and equipment, including significant betterments to existing facilities, are recorded at cost. Upon retirement or disposal, the cost and accumulated depreciation are removed from the accounts and any gain or loss is included in the consolidated statements of operations. Maintenance and repair costs are charged against earnings as incurred.

The Company reviews its property and equipment as an event occurs or circumstances change that would more likely than not reduce the fair value of the property and equipment below the carrying amount. If the carrying amount of property and equipment is not recoverable from its undiscounted cash flows, then the Company would recognize an impairment loss for the difference between the carrying amount and the current fair value. Further, the Company evaluates the remaining useful lives of property and equipment at each reporting period to determine whether events and circumstances warrant a revision to the remaining depreciation periods.

Depreciation

Depreciation. Depreciation expense is computed principally using the straight-line method over the estimated useful lives of the assets. Annual depreciation rates are as follows: buildings and land improvements, 2 to 10 percent, and machinery and equipment, 5 to 33 percent. Depreciation expense was $192 million, $234 million and $249 million in 2012, 2011 and 2010, respectively. Such depreciation expense included accelerated depreciation of $28 million (primarily in the Cabinets and Related Products and Plumbing Products segments), $52 million (primarily in the Cabinets and Related Products and Other Specialty Products segments) and $43 million (primarily in the Cabinets and Related Products segment) in 2012, 2011 and 2010, respectively.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets. The Company performs its annual impairment testing of goodwill in the fourth quarter of each year, or as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company has defined its reporting units and completed the impairment testing of goodwill at the operating segment level. The Company’s operating segments are reporting units that engage in business activities, for which discrete financial information, including five-year forecasts, are available. The Company compares the fair value of the reporting units to the carrying value of the reporting units for goodwill impairment testing. Fair value is determined using a discounted cash flow method, which includes significant unobservable inputs (Level 3 inputs).

Determining market values using a discounted cash flow method requires the Company to make significant estimates and assumptions, including long-term projections of cash flows, market conditions and appropriate discount rates. The Company’s judgments are based upon historical experience, current market trends, consultations with external valuation specialists and other information. In estimating future cash flows, the Company relies on internally generated five-year forecasts for sales and operating profits, including capital expenditures, and generally a one to three percent long-term assumed annual growth rate of cash flows for periods after the five-year forecast. The Company utilizes its weighted average cost of capital of approximately 9.5 percent as the basis to determine the discount rate to apply to the estimated future cash flows. In 2012, due to market conditions, the Company increased the discount rate to a range of 11 percent to 13 percent for most of its reporting units. The Company records an impairment to goodwill (adjusting the value to the estimated fair value) if the book value exceeds the estimated fair value.

The Company reviews its other indefinite-lived intangible assets for impairment annually in the fourth quarter of each year, or as events occur or circumstances change that indicate the assets may be impaired without regard to the reporting unit. The Company considers the implications of both external (e.g., market growth, competition and local economic conditions) and internal (e.g., product sales and expected product growth) factors and their potential impact on cash flows related to the intangible asset in both the near- and long-term.

Intangible assets with finite useful lives are amortized using the straight-line method over their estimated useful lives. The Company evaluates the remaining useful lives of amortizable intangible assets at each reporting period to determine whether events and circumstances warrant a revision to the remaining periods of amortization. See Note H for additional information regarding Goodwill and Other Intangible Assets.

Fair Value Accounting

Fair Value Accounting. The Company follows accounting guidance for its financial investments and liabilities which defines fair value, establishes a framework for measuring fair value and prescribes disclosures about fair value measurements. The Company also follows this guidance for its non-financial investments and liabilities.

The fair value of financial investments and liabilities is determined at each balance sheet date and future declines in market conditions, the future performance of the underlying investments or new information could affect the recorded values of the Company’s investments in marketable securities, private equity funds and other private investments.

The Company uses derivative financial instruments to manage certain exposure to fluctuations in earnings and cash flows resulting from changes in foreign currency exchange rates, commodity costs and interest rate exposures. Derivative financial instruments are recorded in the consolidated balance sheets as either an asset or liability measured at fair value. For each derivative financial instrument that is designated and qualifies as a fair-value hedge, the gain or loss on the derivative instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in determining current earnings during the period of the change in fair values. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in determining current earnings during the period of the change in fair value.

Warranty

Warranty. At the time of sale, the Company accrues a warranty liability for the estimated cost to provide products, parts or services to repair or replace products in satisfaction of warranty obligations. The Company’s estimate of costs to service its warranty obligations is based upon the information available and includes a number of factors such as the warranty coverage, the warranty period, historical experience specific to the nature, frequency and average cost to service the claim, along with product manufacturing metrics and industry and demographic trends.

Certain factors and related assumptions in determining our warranty liability involve judgments and estimates and are sensitive to changes in the aforementioned factors. The Company believes that the warranty accrual is appropriate; however, actual claims incurred could differ from the original estimates thereby requiring adjustments to previously established accruals.

A majority of the Company’s business is at the consumer retail level through home centers and major retailers. A consumer may return a product to a retail outlet that is a warranty return. However, certain retail outlets do not distinguish between warranty and other types of returns when they claim a return deduction from the Company. The Company’s revenue recognition policy takes into account this type of return when recognizing revenue, and deductions are recorded at the time of sale.

Product Liability

Product Liability. The Company provides for expenses associated with product liability obligations when such amounts are probable and can be reasonably estimated. The accruals are adjusted as new information develops or circumstances change that would affect the estimated liability.

Stock-Based Compensation

Stock-Based Compensation. The Company measures compensation expense for stock awards at the market price of the Company’s common stock at the grant date. Effective January 1, 2006, such expense is being recognized ratably over the shorter of the vesting period of the stock awards, typically 5 to 10 years (except for stock awards held by grantees age 66 or older, which vest over five years), or the length of time until the grantee becomes retirement-eligible at age 65. For stock awards granted prior to January 1, 2006, such expense is being recognized over the vesting period of the stock awards, typically 10 years, or for executive grantees that are, or will become, retirement-eligible during the vesting period, the expense is being recognized over five years or immediately upon a grantee’s retirement.

The Company measures compensation expense for stock options using a Black-Scholes option pricing model. Such expense is being recognized ratably over the shorter of the vesting period of the stock options, typically five years, or the length of time until the grantee becomes retirement-eligible at age 65. The Company utilizes the shortcut method to determine the tax windfall pool associated with stock options.

Noncontrolling Interest

Noncontrolling Interest. The Company owns 68 percent of Hansgrohe AG at both December 31, 2012 and 2011. The aggregate noncontrolling interest, net of dividends, at December 31, 2012 and 2011 has been recorded as a component of equity on the Company’s consolidated balance sheets.

Interest and Penalties on Uncertain Tax Positions

Interest and Penalties on Uncertain Tax Positions. The Company records interest and penalties on its uncertain tax positions in income tax expense.

Reclassifications

Reclassifications. Certain prior-year amounts have been reclassified to conform to the 2012 presentation in the consolidated financial statements. In the Company’s consolidated statements of cash flows, the cash flows from discontinued operations are not separately classified.

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements. On January 1, 2012, the Company adopted new accounting guidance requiring more prominent presentation of other comprehensive income items in the Company’s consolidated financial statements. The adoption of this new guidance did not have an impact on the Company’s financial position or its results of operations.

Equity [Abstract]

Shareholders' Equity

N. SHAREHOLDERS’ EQUITY

In July 2007, the Company’s Board of Directors authorized the repurchase for retirement of up to 50 million shares of the Company’s common stock in open-market transactions or otherwise. At December 31, 2012, the Company had remaining authorization to repurchase up to 24 million shares. During 2012, the Company repurchased and retired one million shares of Company common stock, for cash aggregating $8 million to offset the dilutive impact of the 2012 grant of one million shares of long-term stock awards. The Company repurchased and retired two million common shares in 2011 and three million common shares in 2010 for cash aggregating $30 million and $45 million in 2011 and 2010, respectively.

On the basis of amounts paid (declared), cash dividends per common share were $.30 ($.30) in 2012, $.30 ($.30) in 2011 and $.30 ($.30) in 2010, respectively.

All of the notes and debentures above are senior indebtedness and, other than the 6.625% notes due 2018 and the 7.75% notes due 2029, are redeemable at the Company’s option.

On March 5, 2012, the Company issued $400 million of 5.95% Notes (“the Notes”) due March 15, 2022. Including the interest rate swap amortization, the effective interest rate for the Notes is approximately 6.5%, see Note F. The Notes are senior indebtedness and are redeemable at the Company’s option.

In January 2012, the Company repurchased $46 million of 5.875% Notes due July 15, 2012 in open-market transactions; the Company paid a premium of $1 million for the repurchase. In July 2012, the Company retired all of its $745 million of 5.875% Notes on the scheduled retirement date.

On June 21, 2010, the Company 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 January 10, 2014. On February 11, 2011, the Company entered into an amendment (deemed to be effective and applicable as of December 31, 2010) of the Credit Agreement with its bank group (the “Amendment”).

On February 13, 2012, the Company entered into another amendment (deemed to be effective and applicable as of December 31, 2011) of the Credit Agreement (the “Second Amendment”). The Credit Agreement contains financial covenants requiring the Company to maintain a maximum debt to total adjusted capitalization ratio of 65 percent. The Second Amendment provides for the add-back to shareholders’ equity in the Company’s debt to capitalization covenant of (i) certain non-cash charges (including impairment charges for financial investments and goodwill and other intangible assets) and (ii) changes to the valuation allowance on the Company’s deferred tax assets included in income tax expense. The Second Amendment also permits the Company to add back, if incurred, up to $250 million in the aggregate of future non-cash charges subsequent to December 31, 2011. The Second Amendment revised the permitted ratio of consolidated EBITDA to consolidated interest expense to 2.25 to 1.00 through December 31, 2012, increasing to 2.50 to 1.00 with respect to each quarter thereafter.

The Credit Agreement provides for an unsecured revolving credit facility available to the Company and one of its 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. The Company can also borrow swingline loans up to $150 million and obtain Letters of Credit of up to $250 million. Any outstanding Letters of Credit reduce the Company’s borrowing capacity. At December 31, 2012, the Company had $78 million of outstanding and unused Letters of Credit, reducing the Company’s borrowing capacity by such amount.

Revolving credit loans bear interest under the Credit Agreement, at the Company’s option: at (A) a rate per annum equal to the greatest of (i) 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 the then-applicable corporate credit ratings of the Company; or (B) LIBOR plus an applicable margin based upon the then-applicable corporate credit ratings of the Company. The foreign currency revolving credit loans bear interest at a rate equal to LIBOR plus an applicable margin based upon the then-applicable corporate credit ratings of the Company.

Based on the limitations of the debt to total capitalization covenant, at December 31, 2012 the Company had additional borrowing capacity, subject to availability, of up to $873 million. Additionally, at December 31, 2012, the Company could absorb a reduction to shareholders’ equity of approximately $470 million and remain in compliance with the debt to total capitalization covenant.

In order to borrow under the Credit Agreement, there must not be any default in the Company’s covenants in the 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 the Company’s representations and warranties in the 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, 2009, in each case, no material ERISA or environmental non-compliance and no material tax deficiency).

At December 31, 2012 and 2011, the Company was in compliance with all covenants and had no borrowings under the Credit Agreement.

At December 31, 2012, the debt maturities during each of the next five years were as follows: 2013—$206 million; 2014—$1 million; 2015—$501 million; 2016—$1,001 million; and 2017—$301 million.

Interest paid was $269 million, $254 million and $241 million in 2012, 2011 and 2010, respectively.

The Company leases certain equipment and plant facilities under noncancellable operating leases. Rental expense recorded in the consolidated statements of operations totaled approximately $94 million, $102 million and $110 million during 2012, 2011 and 2010, respectively. Future minimum lease payments at December 31, 2012 were approximately as follows: 2013—$90 million; 2014—$42 million; 2015—$29 million; 2016—$20 million; 2017—$13 million; and 2018 and beyond—$62 million.

The Company leases operating facilities from certain related parties, primarily former owners (and in certain cases, current management personnel) of companies acquired. The Company recorded rental expense to such related parties of approximately $5 million, $5 million and $6 million in 2012, 2011 and 2010, respectively.

As a result of its business rationalization activities over the last several years, at December 31, 2012 and 2011, the Company was holding several facilities for sale, within the Cabinets and Related Products segment and the Other Specialty Products segment. At December 31, 2012 and 2011, the net book value of those facilities was approximately $14 million and $49 million, respectively, and approximates fair value. Fair value was estimated using a market approach, considering the estimated fair values for the other comparable buildings in the areas where the facilities are located, Level 3 inputs.

In the fourth quarter of 2012, the Company determined that the estimated fair value calculated for one business unit in the Plumbing Products segment was lower than the net book value of that business unit. The Company assessed the long-lived assets associated with that business unit and determined that no impairment was necessary at December 31, 2012.

Fair Value Disclosures [Abstract]

Fair Value of Financial Investments and Liabilities

E. FAIR VALUE OF FINANCIAL INVESTMENTS AND LIABILITIES

Accounting Policy. The Company follows accounting guidance that defines fair value, establishes a framework for measuring fair value and prescribes disclosures about fair value measurements for its financial investments and liabilities. The guidance defines fair value as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Further, it defines a fair value hierarchy, as follows: Level 1 inputs as quoted prices in active markets for identical assets or liabilities; Level 2 inputs as observable inputs other than Level 1 prices, such as quoted market prices for similar assets or liabilities or other inputs that are observable or can be corroborated by market data; and Level 3 inputs as unobservable inputs that are supported by little or no market activity and that are financial instruments whose value is determined using pricing models or instruments for which the determination of fair value requires significant management judgment or estimation.

Financial investments that are available to be traded on readily accessible stock exchanges (domestic or foreign) are considered to have active markets and have been valued using Level 1 inputs. Financial investments that are not available to be traded on a public market or have limited secondary markets, or contain provisions that limit the ability to sell the investment are considered to have inactive markets and have been valued using Level 2 or 3 inputs. The Company incorporated credit risk into the valuations of financial investments by estimating the likelihood of non-performance by the counterparty to the applicable transactions. The estimate included the length of time relative to the contract, financial condition of the counterparty and current market conditions. The criteria for determining if a market was active or inactive were based on the individual facts and circumstances.

Financial Investments. The Company has maintained investments in available-for-sale securities and a number of private equity funds and other private investments, principally as part of its tax planning strategies, as any gains enhance the utilization of any current and future tax capital losses.

Financial investments included in other assets were as follows, in millions:

	At December 31
	2012		2011
Auction rate securities	$	22	$	22
Total recurring investments		22		22
Private equity funds		69		86
Other investments		4		4
Total non-recurring investments		73		90
Total	$	95	$	112

The Company’s investments in available-for-sale securities at December 31, 2012 and 2011 were as follows, in millions:

			Pre-tax
	Cost Basis		Unrealized Gains		Unrealized Losses		Recorded Basis
December 31, 2012	$	19	$	3	$	—	$	22
December 31, 2011	$	19	$	3	$	—	$	22

The Company’s investments in private equity funds and other private investments are carried at cost. At December 31, 2012, the Company has investments in 15 venture capital funds, with an aggregate carrying value of $16 million. The venture capital funds invest in start-up or smaller, early-stage established businesses, principally in the information technology, bio-technology and health care sectors. At December 31, 2012, the Company also has investments in 21 buyout funds, with an aggregate carrying value of $53 million. The buyout funds invest in later-stage, established businesses and no buyout fund has a concentration in a particular sector.

Recurring Fair Value Measurements. For financial investments measured at fair value on a recurring basis at each reporting period, the unrealized gains or losses (that are deemed to be temporary) are recognized, net of tax effect, through shareholders’ equity, as a component of other comprehensive income. Realized gains and losses and charges for other-than-temporary impairments are included in determining net income, with related purchase costs based upon specific identification.

For marketable securities, the Company reviews, on a recurring basis, industry analyst reports, key ratios and statistics, market analyses and other factors for each investment to determine if an unrealized loss is other-than-temporary.

In the past, the Company invested excess cash in auction rate securities. Auction rate securities are investment securities that have interest rates which are reset every 7, 28 or 35 days. The fair values of the auction rate securities held by the Company have been estimated, on a recurring basis, using a discounted cash flow model (Level 3 input). The significant inputs in the discounted cash flow model used to value the auction rate securities include: expected maturity of auction rate securities, discount rate used to determine the present value of expected cash flows and assumptions for credit defaults, since the auction rate securities are backed by credit default swap agreements.

During 2011, the Company sold 1,974,000 shares of its investment in TriMas common stock for cash of $43 million; at December 31, 2012 and 2011, the Company did not own any shares of TriMas common stock.

Financial investments and (liabilities) measured at fair value on a recurring basis at each reporting period and the amounts for each level within the fair value hierarchy were as follows, in millions:

Non-Recurring Fair Value Measurements. It is not practicable for the Company to estimate a fair value for private equity funds and other private investments because there are no quoted market prices, and sufficient information is not readily available for the Company to utilize a valuation model to determine the fair value for each fund. These investments are evaluated, on a non-recurring basis, for potential other-than-temporary impairment when impairment indicators are present, or when an event or change in circumstances has occurred, that may have a significant adverse effect on the fair value of the investment.

Impairment indicators the Company considers include the following: whether there has been a significant deterioration in earnings performance, asset quality or business prospects; a significant adverse change in the regulatory, economic or technological environment; a significant adverse change in the general market condition or geographic area in which the investment operates; industry and sector performance; current equity and credit market conditions; and any bona fide offers to purchase the investment for less than the carrying value. The Company also considers specific adverse conditions related to the financial health of and business outlook for the fund, including industry and sector performance. The significant assumptions utilized in analyzing a fund for potential other-than-temporary impairment include current economic conditions, market analysis for specific funds and performance indicators in the residential and commercial construction, bio-technology, health care and information technology sectors in which the applicable funds’ investments operate. Since there is no active trading market for these investments, they are for the most part illiquid. These investments, by their nature, can also have a relatively higher degree of business risk, including financial leverage, than other financial investments. Future changes in market conditions, the future performance of the underlying investments or new information provided by private equity fund managers could affect the recorded values of such investments and the amounts realized upon liquidation. Due to the significant unobservable inputs, the fair value measurements used to evaluate impairment are a Level 3 input.

Financial investments measured at fair value on a non-recurring basis during 2012 and the amounts for each level within the fair value hierarchy were as follows, in millions:

			Fair Value Measurements Using
	Dec. 31, 2012		Quoted Market Prices (Level 1)		Significant Other Observable Unobservable Inputs (Level 2)		Significant Total Inputs (Level 3)		Gains (Losses)
Private equity funds	$	2	$	—	$	—	$	2	$	(2	)
	$	2	$	—	$	—	$	2	$	(2	)

During 2011, there were no financial investments measured on a non-recurring basis. None of the Company’s investments in private equity funds, for which fair value was determined, had unrealized losses in 2012 or 2011.

The remaining private equity investments in 2012 with an aggregate carrying value of $67 million, were not reviewed for impairment, as there were no indicators of impairment or identified events or changes in circumstances that would have a significant adverse effect on the fair value of the investment. The Company did not have any transfers between Level 1 and Level 2 financial assets in 2012 or 2011.

Realized Gains (Losses) and Impairment Charges. During July 2012, based on information from a fund manager, the Company determined that the decline in estimated value of one private equity fund (with an aggregate carrying value of $4 million prior to impairment) was other-than-temporary and, accordingly, recognized non-cash pre-tax impairment charges of $2 million. During 2010, based on information from the fund managers, the Company determined that the decline in the estimated value of three private equity funds (with an aggregate carrying value of $6 million prior to impairment) was other-than-temporary and, accordingly, recognized non-cash, pre-tax impairment charges of $4 million. During 2010, the Company also determined that the decline in the estimated value of one private investment was other-than-temporary and, accordingly, recognized a non-cash, pre-tax impairment charge of $2 million.

Income from financial investments, net, included in other, net, within other income (expense), net, and impairment charges for financial investments were as follows, in millions:

	2012			2011		2010
Realized gains from marketable securities	$	—		$	41	$	10

During 2010, the Company and Asahi Tec agreed to amend the preferred stock to include a more favorable conversion feature into common stock and to include a mandatory conversion date of February 28, 2011. As a result of the amendment, the Company recognized a $28 million impairment loss based on the current fair value of the preferred stock on an if-converted basis in 2010. During the last six months of 2010, the Company converted all its holdings of Asahi Tec preferred stock into common stock which was sold, in its entirety, in open market transactions. The Company realized cash proceeds of $11 million and realized losses aggregating $8 million in 2010. As a result of the disposition of the Asahi Tec common stock, the Company received a tax refund of $16 million in 2011 relating to the utilization of a loss carryback to offset taxes paid on prior capital gains.

The impairment charges related to the Company’s financial investments recognized during 2012 and 2010 were based upon then-current estimates for the fair value of certain financial investments; such estimates could change in the near-term based upon future events and circumstances.

The fair value of the Company’s short-term and long-term fixed-rate debt instruments is based principally upon modeled market prices for the same or similar issues or the current rates available to the Company for debt with similar terms and remaining maturities. The aggregate estimated market value of short-term and long-term debt at December 31, 2012 was approximately $4.0 billion, compared with the aggregate carrying value of $3.6 billion. The aggregate estimated market value of short-term and long-term debt at December 31, 2011 was approximately $4.0 billion, compared with the aggregate carrying value of $4.0 billion.

Derivative Instruments and Hedging Activities

F. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Company is exposed to global market risk as part of its normal daily business activities. To manage these risks, the Company enters into various derivative contracts. These contracts include interest rate swap agreements, foreign currency exchange contracts and contracts intended to hedge the Company’s exposure to copper and zinc. The Company reviews its hedging program, derivative positions and overall risk management on a regular basis.

Interest Rate Swap Agreements. In March 2012, in connection with the issuance of $400 million of debt, the Company terminated the interest rate swap hedge relationships that it had entered into in August 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 approximately $2 million loss was recognized in the Company’s consolidated statement of operations in other, 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 December 31, 2012, the balance remaining was $21 million. At December 31, 2011, the interest rate swaps were considered 100 percent effective; therefore, the market valuation of $23 million was recorded in other comprehensive income in the Company’s statement of shareholders’ equity with a corresponding increase to accrued other in the Company’s condensed consolidated balance sheet at December 31, 2011.

In 2012, the Company recognized a decrease in interest expense of $6 million, offset by interest expense of $2 million related to the cash flow hedge terminated in March 2012. In 2011 and 2010, the Company recognized a decrease in interest expense of $10 million and $12 million, respectively, related to the amortization of gains resulting from the terminations (in 2008 and 2004) of two fair value interest rate swap agreements.

Foreign Currency Contracts. The Company’s 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 during 2012, 2011 and 2010, the Company, including certain European operations, entered into foreign currency forward contracts and foreign currency exchange contracts.

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

Metals Contracts. During 2012, 2011 and 2010, the Company entered into several contracts to manage its exposure to increases in the price of copper and zinc. Gains (losses) related to these contracts are recorded in the Company’s consolidated statements of operations in cost of sales.

The pre-tax (losses) gains included in the Company’s consolidated statements of operations are as follows, in millions:

(A) Additions include acquisitions.

(B) During 2011, the Company reclassified the goodwill related to the business units held for sale. Subsequent to the reclassification, the Company recognized a charge for those business units expected to be divested at a loss; the charge included a write-down of goodwill of $13 million.

(C) Other principally includes the effect of foreign currency translation and purchase price adjustments related to prior-year acquisitions.

In the fourth quarters of 2012 and 2011, the Company completed its annual impairment testing of goodwill and other indefinite-lived intangible assets. The impairment test in 2012 indicated there was no impairment of goodwill for any of the Company’s reporting units.

The impairment test in 2011 indicated that goodwill recorded for certain of the Company’s reporting units was impaired. The Company recognized the non-cash, pre-tax impairment charges, in continuing operations, for goodwill of $442 million ($286 million, after tax) for 2011. In 2011, the pre-tax impairment charge in the Decorative Architectural Products segment relates to the builders’ hardware business and reflects increasing competitive conditions for that business. The pre-tax impairment charge in the Other Specialty Products segment relates to the North American window and door business and reflects the continuing weak level of new home construction activity in the western U.S., the reduced levels of repair and remodel activity and the expectation that recovery in these segments will be modestly slower than anticipated. The Company then assessed the long-lived assets associated with these business units and determined no impairment was necessary at December 31, 2011.

Other indefinite-lived intangible assets were $132 million and $174 million at December 31, 2012 and 2011, respectively, and principally included registered trademarks. In 2012 and 2011, the impairment test indicated that the registered trademark for a North American business unit in the Other Specialty Products segment and the registered trademark for a North American business unit in the Plumbing Products segment (2011 only) were impaired due to changes in the long-term outlook for the business units. The Company recognized non-cash, pre-tax impairment charges for other indefinite-lived intangible assets of $42 million ($27 million, after tax) and $8 million ($5 million, after tax) in 2012 and 2011, respectively. In 2010, the Company recognized non-cash, pre-tax impairment charges for other indefinite-lived intangible assets of $10 million ($6 million after tax) related to the Installation and Other Services segment ($9 million pre-tax) and the Plumbing Products segment ($1 million pre-tax).

The carrying value of the Company’s definite-lived intangible assets was $19 million at December 31, 2012 (net of accumulated amortization of $57 million) and $22 million at December 31, 2011 (net of accumulated amortization of $54 million) and principally included customer relationships and non-compete agreements, with a weighted average amortization period of 6 years in both 2012 and 2011. Amortization expense related to the definite-lived intangible assets of continuing operations was $6 million in each of 2012, 2011 and 2010.

At December 31, 2012, amortization expense related to the definite-lived intangible assets during each of the next five years was as follows: 2013—$5 million; 2014—$4 million; 2015—$4 million; 2016—$2 million; and 2017—$1 million.

Compensation And Retirement Disclosure [Abstract]

Employee Retirement Plans

M. EMPLOYEE RETIREMENT PLANS

The Company sponsors qualified defined-benefit and defined-contribution retirement plans for most of its employees. In addition to the Company’s qualified defined-benefit pension plans, the Company has unfunded non-qualified defined-benefit pension plans covering certain employees, which provide for benefits in addition to those provided by the qualified pension plans. Substantially all salaried employees participate in non-contributory defined-contribution retirement plans, to which payments are determined annually by the Organization and Compensation Committee of the Board of Directors. Aggregate charges to earnings under the Company’s defined-benefit and defined-contribution retirement plans were $36 million and $43 million in 2012, $34 million and $31 million in 2011 and $34 million and $47 million in 2010, respectively.

In addition, the Company participates in 20 regional multi-employer pension plans, principally related to building trades; none of the plans are considered significant. The aggregate expense recognized through contributions by the Company to these plans was approximately $4 million, $3 million and $3 million in 2012, 2011 and 2010, respectively.

In March 2009, based on management’s recommendation, the Board of Directors approved a plan to freeze all future benefit accruals under substantially all of the Company’s domestic qualified and non-qualified defined-benefit pension plans. The freeze was effective January 1, 2010.

Changes in the projected benefit obligation and fair value of plan assets, and the funded status of the Company’s defined-benefit pension plans were as follows, in millions:

The Company expects to recognize $18 million of pre-tax net loss from accumulated other comprehensive income into net periodic pension cost in 2013 related to its defined-benefit pension plans.

Plan Assets. The Company’s qualified defined-benefit pension plan weighted average asset allocation, which is based upon fair value, was as follows:

	At December 31
	2012			2011
Equity securities		44	%		44	%
Debt securities		41	%		39	%
Other		15	%		17	%
Total		100	%		100	%

Plan assets included 600,000 and 1.2 million shares of Company common stock valued at $10 million and $12 million at December 31, 2012 and 2011, respectively.

The Company’s qualified defined-benefit pension plans have adopted accounting guidance that defines fair value, establishes a framework for measuring fair value and prescribes disclosures about fair value measurements. Accounting guidance defines fair value as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.”

Following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2012.

Common and Preferred Stocks and Short-Term and Other Investments: Valued at the closing price reported on the active market on which the individual securities are traded, or based on the active market for similar securities. For certain Short-Term and Other Investments, there is no active trading market and they are for the most part illiquid. Due to the significant unobservable inputs, the fair value measurements used to estimate fair value are Level 3 inputs.

Private Equity Funds: Valued based on an estimated fair value using either a market approach or an income approach, each of which requires a significant degree of judgment. There is no active trading market for these investments and they are for the most part illiquid. Due to the significant unobservable inputs, the fair value measurements used to estimate fair value are a Level 3 input.

Corporate Debt Securities: Valued based on the active market for similar securities or on estimated fair value.

Government and Other Debt Securities: Valued based on either the closing price reported on the active market on which the individual securities are traded, the market for similar securities or estimated fair value based on a model for similar securities.

Common Collective Trust Fund: Valued based on a unit value basis, which approximates fair value as of December 31, 2012 and 2011, respectively. Such basis is determined by reference to the respective fund’s underlying assets, which are primarily marketable equity and fixed income securities. There are no unfunded commitments or other restrictions associated with this fund.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

The following table sets forth by level, within the fair value hierarchy, the qualified defined-benefit pension plan assets at fair value as of December 31, 2012 and 2011, in millions.

Assumptions. Major assumptions used in accounting for the Company’s defined-benefit pension plans were as follows:

	December 31
	2012			2011			2010
Discount rate for obligations		3.80	%		4.40	%		5.30	%
Expected return on plan assets		7.25	%		7.25	%		7.25	%
Rate of compensation increase		—	%		—	%		1.00	%
Discount rate for net periodic pension cost		4.40	%		5.30	%		5.80	%

The discount rate for obligations for 2012 and 2011 was based upon the expected duration of each defined-benefit pension plan’s liabilities matched to the December 31, 2012 and 2011 Towers Watson Rate Link Curve. At December 31, 2012, such rates for the Company’s defined-benefit pension plans ranged from 1.75 percent to 4.50 percent, with the most significant portion of the liabilities having a discount rate for obligations of 3.40 percent or higher. At December 31, 2011, such rates for the Company’s defined-benefit pension plans ranged from 2.00 percent to 5.50 percent, with the most significant portion of the liabilities having a discount rate for obligations of 4.20 percent or higher. The decline in the weighted average discount rate over the last several years is principally the result of lower long-term interest rates in the bond markets. The weighted average discount rates were also affected by the freezing of all future benefit accruals for substantially all of the Company’s domestic qualified and non-qualified defined-benefit plans, which shortened the period of future payments.

For 2012 and 2011, the Company determined the expected long-term rate of return on plan assets of 7.25 percent based upon an analysis of expected and historical rates of return of various asset classes utilizing the current and long-term target asset allocation of the plan assets. The projected asset return at both December 31, 2012 and 2011 also considered near term returns, including current market conditions and also that pension assets are long-term in nature. The actual annual rate of return on the Company’s pension plan assets was 6.9 percent and 3.2 percent for the 10-year periods ended December 31, 2012 and 2011, respectively. Although these rates of return are less than the Company’s current expected long-term rate of return on plan assets, the Company notes that the 10-year period ended December 31, 2012 includes one significant decline in the equity markets. In 2012, actual annual rate of return on the Company’s pension plan assets was 17 percent. Accordingly, the Company believes a 7.25 percent expected long-term rate of return is reasonable.

The investment objectives seek to minimize the volatility of the value of the Company’s plan assets relative to pension liabilities and to ensure plan assets are sufficient to pay plan benefits. In 2012 and 2011, the Company achieved its targeted asset allocation: 45 percent equities, 25 percent fixed-income, 15 percent global assets (combination of equity and fixed-income) and 15 percent alternative investments (such as private equity, commodities and hedge funds). The asset allocation of the investment portfolio was developed with the objective of achieving the Company’s expected rate of return and reducing volatility of asset returns, and considered the freezing of future benefits. The equity portfolios are invested in individual securities or funds that are expected to mirror broad market returns for equity securities. The fixed-income portfolio is invested in corporate bonds, bond index funds or U.S. Treasury securities. The increased allocation to fixed-income securities partially matches the bond-like and long-term nature of the pension liabilities. It is expected that the alternative investments would have a higher rate of return than the targeted overall long-term return of 7.25 percent. However, these investments are subject to greater volatility, due to their nature, than a portfolio of equities and fixed-income investments, and would be less liquid than financial instruments that trade on public markets. This portfolio is expected to yield a long-term rate of return of 7.25 percent.

The fair value of the Company’s plan assets is subject to risk including significant concentrations of risk in the Company’s plan assets related to equity, interest rate and operating risk. In order to ensure plan assets are sufficient to pay benefits, a portion of plan assets is allocated to equity investments that are expected, over time, to earn higher returns with more volatility than fixed-income investments which more closely match pension liabilities. Within equity, risk is mitigated by targeting a portfolio that is broadly diversified by geography, market capitalization, manager mandate size, investment style and process.

In order to minimize asset volatility relative to the liabilities, a portion of plan assets are allocated to fixed-income investments that are exposed to interest rate risk. Rate increases generally will result in a decline in fixed-income assets, while reducing the present value of the liabilities. Conversely, rate decreases will increase fixed income assets, partially offsetting the related increase in the liabilities.

Potential events or circumstances that could have a negative effect on estimated fair value include the risks of inadequate diversification and other operating risks. To mitigate these risks, investments are diversified across and within asset classes in support of investment objectives. Policies and practices to address operating risks include ongoing manager oversight, plan and asset class investment guidelines and instructions that are communicated to managers, and periodic compliance and audit reviews to ensure adherence to these policies. In addition, the Company periodically seeks the input of its independent advisor to ensure the investment policy is appropriate.

Other. The Company sponsors certain post-retirement benefit plans that provide medical, dental and life insurance coverage for eligible retirees and dependents in the United States based upon age and length of service. The aggregate present value of the unfunded accumulated post-retirement benefit obligation was $12 million and $14 million at December 31, 2012 and 2011, respectively.

Cash Flows. At December 31, 2012, the Company expected to contribute approximately $36 million to its qualified defined-benefit pension plans to meet ERISA requirements in 2013. The Company also expected to pay benefits of $7 million and $12 million to participants of its foreign and non-qualified (domestic) defined-benefit pension plans, respectively, in 2013.

At December 31, 2012, the benefits expected to be paid in each of the next five years, and in aggregate for the five years thereafter, relating to the Company’s defined-benefit pension plans, were as follows, in millions:

Net deferred tax liability at December 31	$	280		$	239

At December 31, 2012 and 2011, the net deferred tax liability consisted of net short-term deferred tax assets included in prepaid expenses and other of $41 million and $11 million, respectively, and net long-term deferred tax liabilities included in deferred income taxes and other of $321 million and $250 million, respectively.

The current portion of the state and local income tax benefit includes a $14 million and $10 million tax benefit from the reversal of an accrual for uncertain tax positions resulting primarily from the expiration of applicable statutes of limitations and favorable settlements on state audits in 2012 and 2011, respectively. The deferred portion of the state and local taxes includes a $26 million and $31 million non-cash charge to income tax expense resulting from a change in the valuation allowance against state and local deferred tax assets in 2012 and 2011, respectively.

The accounting guidance for income taxes requires that the future realization of deferred tax assets depends on the existence of sufficient taxable income in future periods. Possible sources of taxable income include taxable income in carryback periods, the future reversal of existing taxable temporary differences recorded as a deferred tax liability, tax-planning strategies that generate future income or gains in excess of anticipated losses in the carryforward period and projected future taxable income.

If, based upon all available evidence, both positive and negative, it is more likely than not (more than 50 percent likely) such deferred tax assets will not be realized, a valuation allowance is recorded. Significant weight is given to positive and negative evidence that is objectively verifiable. A company’s three-year cumulative loss position is significant negative evidence in considering whether deferred tax assets are realizable and the accounting guidance restricts the amount of reliance the Company can place on projected taxable income to support the recovery of the deferred tax assets.

In the fourth quarter of 2010, the Company recorded a $372 million valuation allowance against its U.S. Federal deferred tax assets as a non-cash charge to income tax expense. In reaching this conclusion, the Company considered the weaker retail sales of certain of its building products and the slower than anticipated recovery in the U.S. housing market which led to U.S. operating losses and significant U.S. goodwill impairment charges, that primarily occurred in the fourth quarter of 2010, causing the Company to be in a three-year cumulative U.S. loss position.

During 2012 and 2011, objective and verifiable negative evidence, such as U.S. operating losses and significant impairment charges for U.S. goodwill in 2011 and other intangible assets, continued to outweigh positive evidence necessary to reduce the valuation allowance. As a result, the Company recorded increases of $65 million and $89 million in the valuation allowance against its U.S. Federal deferred tax assets as a non-cash charge to income tax expense in 2012 and 2011, respectively.

Recording the valuation allowance does not restrict the Company’s ability to utilize the future deductions and net operating losses associated with the deferred tax assets assuming taxable income is recognized in future periods.

A rebound in the U.S. housing market from the recent historic lows and retail sales of building products improving from their current levels should have a positive impact on the Company’s operating results in the U.S. A return to sustained profitability in the U.S. should result in objective positive evidence thereby warranting the potential reversal of all or a portion of the valuation allowance.

The $203 million and $156 million of deferred tax assets at December 31, 2012 and 2011, respectively, for which there is no valuation allowance recorded, is anticipated to be realized through the future reversal of existing taxable temporary differences recorded as deferred tax liabilities.

Of the deferred tax asset related to the net operating loss and tax credit carryforwards at December 31, 2012 $411 million will expire between 2020 and 2032 and $14 million is unlimited. Of the deferred tax asset related to the net operating loss and tax credit carryforwards at December 31, 2011 $269 million will expire between 2020 and 2031 and $11 million is unlimited.

The tax benefit from certain stock-based compensation is not recognized as a deferred tax asset until the tax deduction reduces cash taxes. Accordingly, as of December 31, 2012, the Company has not recorded a $27 million deferred tax asset on additional net operating losses that, when realized, will be recorded to paid-in capital.

A tax provision has not been provided at December 31, 2012 for U.S. income taxes or additional foreign withholding taxes on approximately $10 million of undistributed earnings of certain foreign subsidiaries that are considered to be permanently reinvested. It is not practicable to determine the amount of deferred tax liability on such earnings as the actual U.S. tax would depend on income tax laws and circumstances at the time of distribution.

A reconciliation of the U.S. Federal statutory tax rate to the income tax expense (benefit) on income (loss) from continuing operations was as follows:

	2012			2011			2010
U.S. Federal statutory tax rate – expense (benefit)		35	%		(35	%)		(35	%)
State and local taxes, net of U.S. Federal tax benefit		4			—			1
(Lower) higher taxes on foreign earnings		(9	)		—			(1	)
U.S. and foreign taxes on distributed and undistributed foreign earnings		1			—			—
Goodwill and other intangible assets impairment charges providing no tax benefit		2			3			18
U.S. Federal valuation allowance		89			24			50
Other, net		3			(2	)		(1	)
Effective tax rate – expense (benefit)		125	%		(10	%)		32	%

Income taxes paid were $57 million, $43 million and $47 million in 2012, 2011 and 2010, respectively.

A reconciliation of the beginning and ending liability for uncertain tax positions, including related interest and penalties, is as follows:

							(In millions)
	Uncertain Tax Positions			Interest and Penalties			Total
Balance at January 1, 2011	$	71		$	23		$	94

Interest and penalties recognized in income tax expense		—			(3	)		(3	)
Balance at December 31, 2012	$	51		$	17		$	68

If recognized, $34 million and $40 million of the liability for uncertain tax positions at December 31, 2012 and 2011, respectively, net of any U.S. Federal tax benefit, would impact the Company’s effective tax rate.

At December 31, 2012 and 2011, $74 and $86 million of the total liability for uncertain tax positions, including related interest and penalties, is recorded in deferred income taxes and other, $1 and $1 million is recorded in accrued liabilities and $7 and $6 million is recorded in other assets, respectively.

The Company files income tax returns in the U.S. Federal jurisdiction, and various local, state and foreign jurisdictions. The Company continues to participate in the Compliance Assurance Program (“CAP”). CAP is a real-time audit of the U.S. Federal income tax return that allows the Internal Revenue Service (“IRS”), working in conjunction with the Company, to determine tax return compliance with the U.S. Federal tax law prior to filing the return. This program provides the Company with greater certainty about its tax liability for a given year within months, rather than years, of filing its annual tax return and greatly reduces the need for recording a liability for U.S. Federal uncertain tax positions. The IRS has completed their examination of the Company’s consolidated U.S. Federal tax returns through 2011. With few exceptions, the Company is no longer subject to state or foreign income tax examinations on filed returns for years before 2000.

As a result of tax audit closings, settlements and the expiration of applicable statutes of limitations in various jurisdictions within the next 12 months, the Company anticipates that it is reasonably possible the liability for uncertain tax positions could be reduced by approximately $6 million.

Discontinued Operations And Disposal Groups [Abstract]

Discontinued Operations

B. DISCONTINUED OPERATIONS

The presentation of discontinued operations includes components of the Company that the Company intends to sell, which comprises operations and cash flows that can be clearly distinguished from the rest of the Company.

In early February 2013, the Company determined that its Danish ready-to-assemble cabinet business was no longer core to its long-term growth strategy and, accordingly the Company embarked on a plan for disposition. The disposition is expected to be completed within the next 12 months.

During 2011, the Company determined that several businesses in the Installation and Other Services segment were not core to the Company’s long-term growth strategy. These businesses provide commercial drywall installation, millwork and framing services. During 2012, the Company disposed all of these businesses for net proceeds of $7 million.

The Company has accounted for the business units identified in 2013 and 2011 as discontinued operations. Losses from these discontinued operations were included in loss from discontinued operations, net, in the consolidated statements of operations.

Selected financial information for the discontinued operations during the period owned by the Company, were as follows, in millions:

	2012			2011			2010
Net sales	$	321		$	389		$	409
Operating loss from discontinued operations	$	(44	)	$	(58	)	$	(9	)
Impairment of assets held for sale		(3	)		(130	)		(23	)
Loss on disposal of discontinued operations, net		(6	)		(3	)		—
Loss before income tax		(53	)		(191	)		(32	)
Income tax expense (benefit)		8			(10	)		(16	)
Loss from discontinued operations, net	$	(61	)	$	(181	)	$	(16	)

Included in the impairment of assets held for sale, net in 2011 is the impairment of indefinite and definite-lived intangible assets of $56 million, the impairment of goodwill of $57 million and the impairment of fixed and other assets of $17 million. Included in the loss on disposal of discontinued operations, net in 2011 is $3 million expense reflecting the adjustment of certain assets related to businesses disposed in prior years.

The unusual relationship between income tax expense and loss before income tax in 2012 results primarily from the increase in the deferred tax liability associated with the abandonment of tax basis in indefinite-lived intangibles due to the disposition of certain discontinued operations.

The unusual relationship between income taxes and loss before income taxes in 2011 resulted primarily from certain losses providing no current tax benefit.

The income tax benefit recorded in 2010 relates primarily to the allocation of an income tax benefit to impairment charges on goodwill and other indefinite-lived intangible assets of certain discontinued operations.

The following balance sheet items have been classified as held for sale:

	December 31,
	2012		2011
Receivables	$	32	$	56
Inventories		66		66
Prepaid expenses and other		2		2
Property and equipment, net		103		118

Accounts payable		31		47
Accrued liabilities		14		20
Deferred income taxes		4		12
Total liabilities	$	49	$	79

In the fourth quarter of 2012, the Company determined that the estimated fair value calculated for this business unit was lower than the net book value. The Company assessed the long-lived assets associated with this business unit and determined that no impairment was necessary at December 31, 2012.

Also during 2011, the Company decided to exit a product line in builders’ hardware in the Decorative Architectural Products segment with net sales of $1 million and an operating loss of $15 million in 2011 (including $8 million to write-down inventory related to satisfaction of contractual obligations). In the first quarter of 2012, the Company disposed of this product line. This business was included in continuing operations through the date of disposal.

The Company follows accounting guidance regarding determining whether instruments granted in share-based payment transactions are participating securities. This accounting guidance clarifies that share-based payment awards that entitle their holders to receive non-forfeitable dividends prior to vesting should be considered participating securities. The Company has granted restricted stock awards that contain non-forfeitable rights to dividends on unvested shares; such unvested restricted stock awards are considered participating securities. As participating securities, the unvested shares are required to be included in the calculation of the Company’s basic earnings per common share, using the “two-class method.” The two-class method of computing earnings per common share is an allocation method that calculates earnings per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. For the years ended December 31, 2012, 2011 and 2010, the Company allocated dividends to the unvested restricted stock awards (participating securities).

At December 31, 2011 and 2010, the Company did not include any common shares related to the Zero Coupon Convertible Senior Notes (“Notes”) in the calculation of diluted earnings per common share, as the price of the Company’s common stock at December 31, 2010 did not exceed the equivalent accreted value of the Notes.

Additionally, 30 million common shares, 36 million common shares and 37 million common shares for 2012, 2011 and 2010, respectively, related to stock options were excluded from the computation of diluted earnings per common share due to their antidilutive effect.

Common shares outstanding included on the Company’s balance sheet and for the calculation of earnings per common share do not include unvested stock awards (8 million shares and 10 million common shares at December 31, 2012 and 2011, respectively); shares outstanding for legal requirements included all common shares that have voting rights (including unvested stock awards).

Stock-Based Compensation

L. STOCK-BASED COMPENSATION

The Company’s 2005 Long Term Stock Incentive Plan (the “2005 Plan”) provides for the issuance of stock-based incentives in various forms to employees and non-employee Directors of the Company. At December 31, 2012, outstanding stock-based incentives were in the form of long-term stock awards, stock options, phantom stock awards and stock appreciation rights.

Pre-tax compensation expense (income) and the income tax benefit related to these stock-based incentives were as follows, in millions:

	2012		2011		2010
Long-term stock awards	$	35	$	39	$	37
Stock options		15		21		22
Phantom stock awards and stock appreciation rights		11		1		3
Total	$	61	$	61	$	62
Income tax benefit (37 percent tax rate – before valuation allowance)	$	23	$	23	$	23

At December 31, 2012, a total of 10,718,100 shares of Company common stock were available under the 2005 Plan for the granting of stock options and other long-term stock incentive awards.

Long-Term Stock Awards. Long-term stock awards are granted to key employees and non-employee Directors of the Company and do not cause net share dilution inasmuch as the Company continues the practice of repurchasing and retiring an equal number of shares on the open market.

The Company’s long-term stock award activity was as follows, shares in millions:

	2012		2011		2010
Unvested stock award shares at January 1		10		10		9
Weighted average grant date fair value	$	17	$	19	$	21

Unvested stock award shares at December 31		8		10		10
Weighted average grant date fair value	$	16	$	17	$	19

At December 31, 2012, 2011 and 2010, there was $72 million, $107 million and $127 million, respectively, of unrecognized compensation expense related to unvested stock awards; such awards had a weighted average remaining vesting period of four years for 2012, four years for 2011 and five years for 2010.

The total market value (at the vesting date) of stock award shares which vested during 2012, 2011 and 2010 was $27 million, $28 million and $22 million, respectively.

Stock Options. Stock options are granted to key employees of the Company. The exercise price equals the market price of the Company’s 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. The 2005 Plan does not permit the granting of restoration stock options, except for restoration options resulting from options previously granted under the 1991 Plan. Restoration stock options become exercisable six months from the date of grant.

The Company granted 1,080,750 of stock option shares, including restoration stock option shares, during 2012 with a grant date exercise price of approximately $12 per share. During 2012, 5,894,710 stock option shares were forfeited (including options that expired unexercised).

The Company’s stock option activity was as follows, shares in millions:

	2012			2011			2010

Aggregate intrinsic value (A)	$	22	million	$	4	million	$	4	million
Weighted average remaining option term (in years)		4			4			4

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

At December 31, 2012, 2011 and 2010, there was $15 million, $33 million and $45 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 two years in 2012 and three years in 2011 and 2010.

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, was as follows:

	2012			2011			2010
Weighted average grant date fair value	$	4.44		$	5.07		$	5.30
Risk-free interest rate		1.09	%		2.69	%		2.76	%

Phantom Stock Awards and Stock Appreciation Rights (“SARs”). The Company grants phantom stock awards and SARs to certain non-U.S. employees.

Phantom stock awards are linked to the value of the Company’s common stock on the date of grant and are settled in cash upon vesting, typically over 5 to 10 years. The Company accounts for phantom stock awards as liability-based awards; the compensation expense is initially measured as the market price of the Company’s common stock at the grant date and is recognized over the vesting period. The liability is remeasured and adjusted at the end of each reporting period until the awards are fully-vested and paid to the employees. The Company recognized expense of $7 million, $2 million and $2 million related to the valuation of phantom stock awards for 2012, 2011 and 2010, respectively. In 2012, 2011 and 2010, the Company granted 162,310 shares, 349,550 shares and 299,650 shares, respectively, of phantom stock awards with an aggregate fair value of $2 million, $4 million and $4 million, respectively, and paid $3 million, $2 million and $1 million of cash in 2012, 2011 and 2010, respectively, to settle phantom stock awards.

SARs are linked to the value of the Company’s common stock on the date of grant and are settled in cash upon exercise. The Company accounts for SARs using the fair value method, which requires outstanding SARs to be classified as liability-based awards and valued using a Black-Scholes option pricing model at the grant date; such fair value is recognized as compensation expense over the vesting period, typically five years. The liability is remeasured and adjusted at the end of each reporting period until the SARs are exercised and payment is made to the employees or the SARs expire. The Company recognized expense (income) of $4 million, $(1) million and $1 million related to the valuation of SARs for 2012, 2011 and 2010, respectively. During 2012 and 2011, the Company did not grant any SARs. During 2010, the Company granted SARs for 429,300 shares, with an aggregate fair value of $2 million in 2010.
