2. Significant Accounting Policies

Use of Estimates The presentation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires us to make estimates and assumptions that affect reported amounts and related disclosures. Actual results in future periods could differ from those estimates.

Cash and Cash Equivalents Highly liquid investments with an original maturity of three months or less are included in cash and cash equivalents.

Allowances for Doubtful Accounts Trade receivables are recorded at the stated amount, less allowances for discounts, doubtful accounts and returns. The allowances for doubtful accounts represent estimated uncollectible receivables associated with potential customer defaults on contractual obligations (usually due to customers’ potential insolvency), or discounts related to early payment of accounts receivables by our customers. The allowances include provisions for certain customers where a risk of default has been specifically identified. In addition, the allowances include a provision for customer defaults on a general formula basis when it is determined the risk of some default is probable and estimable, but cannot yet be associated with specific customers. The assessment of the likelihood of customer defaults is based on various factors, including the length of time the receivables are past due, historical collection experience and existing economic conditions. In accordance with this policy, our allowance for doubtful accounts was $6.8 million and $9.0 million as of December 31, 2013 and 2012, respectively.

Inventories The majority of our inventories are accounted for using the first-in, first-out inventory method. Inventory provisions are recorded to reduce inventory to the lower of cost or market value for obsolete or slow moving inventory based on assumptions about future demand and marketability of products, the impact of new product introductions, inventory levels and turns, product spoilage and specific identification of items, such as product discontinuance, engineering/material changes, or regulatory-related changes.

We also use the last-in, first-out (“LIFO”) inventory method in those product groups in which metals inventories comprise a significant portion of our inventories. LIFO inventories at December 31, 2013 and 2012 were $228.8 million (with a current cost of $257.5 million) and $163.6 million (with a current cost of $193.9 million), respectively.

Property, Plant and Equipment Property, plant and equipment are carried at cost. Depreciation is provided, principally on a straight-line basis, over the estimated useful lives of the assets. Gains or losses resulting from dispositions are included in operating income. Betterments and renewals, which improve and extend the life of an asset, are capitalized; maintenance and repair costs are expensed as incurred. Assets held for use to be disposed of at a future date are depreciated over the remaining useful life. Assets to be sold are written down to fair value at the time the assets are being actively marketed for sale. As of December 31, 2013 and 2012, the carrying value of assets held for sale was not material. Estimated useful lives of the related assets are as follows:

Long-lived Assets In accordance with Accounting Standards Codification (“ASC”) requirements for Property, Plant and Equipment, a long-lived asset (including amortizable identifiable intangible assets) or asset group held for use is tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. When such events occur, we compare the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of the long-lived asset or asset group. The cash flows are based on our best estimate of future cash flows derived from the most recent business projections. If this comparison indicates that there is an impairment, the amount of the impairment is calculated based on fair value. Fair value is estimated primarily using discounted expected future cash flows on a market-participant basis.

Goodwill and Indefinite-lived Intangible Assets In accordance with ASC requirements for Intangibles — Goodwill and Other, goodwill is tested for impairment at least annually in the fourth quarter, and written down when impaired. An interim impairment test is performed if an event occurs or conditions change that would more likely than not reduce the fair value of the reporting unit below the carrying value.

We evaluate the recoverability of goodwill using a weighting of the income (80%) and market (20%) approaches. For the income approach, we use a discounted cash flow model, estimating the future cash flows of the reporting units to which the goodwill relates, and then discounting the future cash flows at a market-participant-derived weighted-average cost of capital. In determining the estimated future cash flows, we consider current and projected future levels of income based on management’s plans for that business; business trends, prospects and market and economic conditions; and market-participant considerations. Furthermore, our projection for the U.S. home products market is inherently subject to a number of uncertain factors, such as employment, home prices, credit availability, new home starts and the rate of home foreclosures. For the market approach, we apply market multiples for peer groups to the current operating results of the reporting units to determine each reporting unit’s fair value. The Company’s reporting units are operating segments, or one level below the operating segment. When the estimated fair value of a reporting unit is less than its carrying value, we measure and recognize the amount of the goodwill impairment loss, if any. Impairment losses, limited to the carrying value of goodwill, represent the excess of the carrying value of a reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of a reporting unit is estimated based on a hypothetical allocation of each reporting unit’s fair value to all of its underlying assets and liabilities.

Purchased intangible assets other than goodwill are amortized over their useful lives unless those lives are determined to be indefinite. The determination of the useful life of an intangible asset other than goodwill is based on factors including historical and tradename performance with respect to consumer name recognition, geographic market presence, market share, and plans for ongoing tradename support and promotion. Certain of our tradenames have been assigned an indefinite life as we currently anticipate that these tradenames will contribute cash flows to the Company indefinitely. Indefinite-lived intangible assets are not amortized, but are evaluated at least annually to determine whether the indefinite useful life is appropriate. We review indefinite-lived intangible assets for impairment annually in the fourth quarter, and whenever market or business events indicate there may be a potential impairment of that intangible. Impairment losses are recorded to the extent that the carrying value of the indefinite-lived intangible asset exceeds its fair value. We measure fair value using the standard relief-from-royalty approach which estimates the present value of royalty income that could be hypothetically earned by licensing the brand name to a third party over the remaining useful life. In addition, beginning for 2012 year-end intangible asset impairment testing, we adopted the new Accounting Standards Update that allows us to first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. Qualitative factors include changes in volume, customers and the industry. If it is deemed more likely than not that an intangible asset is impaired, we will perform a quantitative impairment test.

The Company cannot predict the occurrence of certain events or changes in circumstances that might adversely affect the carrying value of goodwill and indefinite-lived intangible assets. Such events may include, but are not limited to, the impact of the economic environment; a material negative change in relationships with significant customers; or strategic decisions made in response to economic and competitive conditions.

Defined Benefit Plans We have a number of pension plans in the United States, covering many of the Company’s employees. In addition, the Company provides postretirement health care and life insurance benefits to certain retirees.

We record amounts relating to these plans based on calculations in accordance with ASC requirements for Compensation — Retirement Benefits, which include various actuarial assumptions, including discount rates, assumed rates of return, compensation increases, turnover rates and health care cost trend rates. We recognize changes in the fair value of pension plan assets and net actuarial gains or losses in excess of 10 percent of the greater of the fair value of pension plan assets or each plan’s projected benefit obligation (the “corridor”) in earnings immediately upon remeasurement, which is at least annually in the fourth quarter of each year. We review our actuarial assumptions on an annual basis and make modifications to the assumptions based on current economic conditions and trends. The discount rate used to measure obligations is based on a spot-rate yield curve on a plan-by-plan basis that matches projected future benefit payments with the appropriate interest rate applicable to the timing of the projected future benefit payments. The expected rate of return on plan assets is determined based on the nature of the plans’ investments, our current asset allocation and our expectations for long-term rates of return. Compensation increases reflect expected future compensation trends. For postretirement benefits, our health care trend rate assumption is based on historical cost increases and expectations for long-term increases. The cost or benefit of plan changes, such as increasing or decreasing benefits for prior employee service (prior service cost), is deferred and included in expense on a straight-line basis over the average remaining service period of the related employees. We believe that the assumptions utilized in recording obligations under our plans, which are presented in Note 12, “Defined Benefit Plans,” are reasonable based on our experience and on advice from our independent actuaries; however, differences in actual experience or changes in the assumptions may materially affect our financial position and results of operations. We will continue to monitor these assumptions as market conditions warrant.

Litigation Contingencies Our businesses are subject to risks related to threatened or pending litigation and are routinely defendants in lawsuits associated with the normal conduct of business. Liabilities and costs associated with litigation-related loss contingencies require estimates and judgments based on our knowledge of the facts and circumstances surrounding each matter and the advice of our legal counsel. We record liabilities for litigation-related losses when a loss is probable and we can reasonably estimate the amount of the loss in accordance with ASC requirements for Contingencies. We evaluate the measurement of recorded liabilities each reporting period based on the then-current facts and circumstances specific to each matter. The ultimate losses incurred upon final resolution of litigation-related loss contingencies may differ materially from the estimated liability recorded at any particular balance sheet date. Changes in estimates are recorded in earnings in the period in which such changes occur.

Income Taxes In accordance with ASC requirements for Income Taxes, we establish deferred tax liabilities or assets for temporary differences between financial and tax reporting bases and subsequently adjust them to reflect changes in tax rates expected to be in effect when the temporary differences reverse. We record a valuation allowance reducing deferred tax assets when it is more likely than not that such assets will not be realized.

We record liabilities for uncertain income tax positions based on a two-step process. The first step is recognition, where we evaluate whether an individual tax position has a likelihood of greater than 50% of being sustained upon examination based on the technical merits of the position, including resolution of any related appeals or litigation processes. For tax positions that are currently estimated to have a less than 50% likelihood of being sustained, no tax benefit is recorded. For tax positions that have met the recognition threshold in the first step, we perform the second step of measuring the benefit to be recorded. The actual benefits ultimately realized may differ from our estimates. In future periods, changes in facts, circumstances, and new information may require us to change the recognition and measurement estimates with regard to individual tax positions. Changes in recognition and measurement estimates are recorded in the consolidated statement of income and consolidated balance sheet in the period in which such changes occur. As of December 31, 2013, we had liabilities for unrecognized tax benefits pertaining to uncertain tax positions totaling $23.7 million. It is reasonably possible that the unrecognized tax benefits may decrease in the range of $2.5 million to $3.5 million in the next 12 months primarily as a result of the conclusion of U.S. federal, state and foreign income tax proceedings.

Revenue Recognition Revenue is recorded when persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed or determinable, and collectibility is reasonably assured. Revenue is recorded net of applicable provisions for discounts, returns and allowances. We record estimates for reductions to revenue for customer programs and incentives, including price discounts, volume-based incentives, promotions and cooperative advertising when revenue is recognized. Sales returns are based on historical returns, current trends and forecasts of product demand.

Cost of Products Sold Cost of products sold includes all costs to make products saleable, such as labor costs, inbound freight, purchasing and receiving costs, inspection costs and internal transfer costs. In addition, all depreciation expense associated with assets used to manufacture products and make them saleable is included in cost of products sold.

Customer Program Costs Customer programs and incentives are a common practice in our businesses. Our businesses incur customer program costs to obtain favorable product placement, to promote sales of products and to maintain competitive pricing. Customer program costs and incentives, including rebates and promotion and volume allowances, are accounted for in either “net sales” or the category “selling, general and administrative expenses” at the time the program is initiated and/or the revenue is recognized. The costs are predominantly recognized in “net sales” and include, but are not limited to, volume allowances and rebates, promotional allowances, and cooperative advertising programs. These costs are recorded at the later of the time of sale or the implementation of the program based on management’s best estimates. Estimates are based on historical and projected experience for each type of program or customer. Volume allowances are accrued based on management’s estimates of customer volume achievement and other factors incorporated into customer agreements, such as new product purchases, store sell-through, merchandising support, level of returns and customer training. Management periodically reviews accruals for these rebates and allowances, and adjusts accruals when circumstances indicate (typically as a result of a change in volume expectations). The costs typically recognized in “selling, general and administrative expenses” include product displays, point of sale materials, and media production costs. The costs included in the “selling, general and administrative expenses” category were $46.0 million, $46.2 million and $47.4 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Selling, General and Administrative Expenses Selling, general and administrative expenses include advertising costs; marketing costs; selling costs, including commissions; research and development costs; shipping and handling costs, including warehousing costs; and general and administrative expenses. Shipping and handling costs included in selling, general and administrative expenses were $189.7 million, $181.3 million and $164.1 million in 2013, 2012 and 2011, respectively.

Advertising costs, which amounted to $205.3 million, $182.4 million and $180.4 million in 2013, 2012 and 2011, respectively, are principally expensed as incurred. Advertising costs include product displays, media production costs, and point of sale materials. Advertising costs recorded as a reduction to net sales, primarily cooperative advertising, were $56.7 million, $49.9 million and $49.8 million in 2013, 2012 and 2011, respectively. Advertising costs recorded in selling, general and administrative expenses were $148.6 million, $132.5 million and $130.6 million in 2013, 2012 and 2011, respectively.

Research and development expenses include product development, product improvement, product engineering and process improvement costs. Research and development expenses, which were $55.6 million, $47.0 million and $35.1 million in 2013, 2012 and 2011, respectively, are expensed as incurred.

Stock-based Compensation Stock-based compensation expense, measured as the fair value of an award on the date of grant, is recognized in the financial statements over the period that an employee is required to provide services in exchange for the award. The fair value of each option award is measured on the date of grant using the Black-Scholes option-pricing model. The fair value of each performance award is based on the stock price at the date of grant and the probability of meeting performance targets. The fair value of each restricted stock unit granted is equal to the share price at the date of grant. See Note 11, “Stock-Based Compensation,” for additional information.

Earnings Per Share Earnings per common share is calculated by dividing net income attributable to Home & Security by the weighted-average number of shares of common stock outstanding during the year. Diluted earnings per common share include the impact of all potentially dilutive securities outstanding during the year. In periods prior to the Separation, the same number of shares was used to calculate basic and diluted earnings per share because no Home & Security stock-based awards were outstanding prior to the Separation. See Note 20, “Earnings Per Share,” for further discussion.

Foreign Currency Translation Foreign currency balance sheet accounts are translated into U.S. dollars at the actual rates of exchange at the balance sheet date. Income and expenses are translated at the average rates of exchange in effect during the period for the foreign subsidiaries where the local currency is the functional currency. The related translation adjustments are made directly to a separate component of the “accumulated other comprehensive income” (“AOCI”) caption in equity. Transactions denominated in a currency other than the functional currency of a subsidiary are translated into functional currency with resulting transaction gains or losses recorded in other expense (income), net.

Derivative Financial Instruments In accordance with ASC requirements for Derivatives and Hedging, all derivatives are recognized as either assets or liabilities on the balance sheet and measurement of those instruments is at fair value. If the derivative is designated as a fair value hedge and is highly effective, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings in the same period. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded directly to a separate component of AOCI, and are recognized in the consolidated statement of income when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow hedges are recognized in earnings.

Net deferred currency gains of $2.3 million and $0.6 million were reclassified into earnings for the years ended December 31, 2013 and 2012, respectively. Net deferred currency losses of $0.5 million were reclassified into earnings in 2011. Based on foreign exchange rates as of December 31, 2013, we estimate that $1.3 million of net currency derivative gains included in AOCI as of December 31, 2013 will be reclassified to earnings within the next twelve months.

Recently Issued Accounting Standards

Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists

In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” ASU 2013-11 provides explicit guidance on presentation in financial statements. The amendment is effective for reporting periods beginning after December 15, 2013 (calendar year 2014 for Home & Security). We believe that adoption of this standard will not have a material impact on our financial statements.

Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity

In March 2013, the FASB issued ASU 2013-05, “Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” ASU 2013-05 clarifies the accounting for the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. The ASU also clarifies the treatment of business combinations achieved in stages involving a foreign entity. The amendment is effective prospectively for reporting periods beginning after December 15, 2013 (calendar year 2014 for Home & Security). We believe that adoption of this standard will not have a material impact on our financial statements.
