INTERIM PRESENTATION	'
	INTERIM PRESENTATION
	The interim financial statements of Leggett & Platt, Incorporated (“we”, “us” or “our”) included herein have not been audited by an independent registered public accounting firm. The statements include all adjustments, including normal recurring accruals, which management considers necessary for a fair presentation of our financial position and operating results for the periods presented. We have prepared the statements pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in conformity with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. The operating results for interim periods are not necessarily indicative of results to be expected for an entire year.
	The December 31, 2013 financial position data included herein was derived from the audited consolidated financial statements included in Form 10-K, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). For further information, refer to the financial statements and footnotes included in our annual report on Form 10-K for the year ended December 31, 2013.
	Reclassifications
	Certain reclassifications have been made to the prior years' consolidated financial statements to conform to the third quarter 2014 presentation, primarily in the Consolidated Statements of Operations and all related notes in which prior periods have been retrospectively adjusted to reflect the reclassification of certain operations to discontinued operations (See Note 5).

NEW ACCOUNTING GUIDANCE	'
	NEW ACCOUNTING GUIDANCE
	In April 2014, the Financial Accounting Standards Board (FASB) issued updated guidance, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This guidance changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. We will adopt this guidance on January 1, 2015, and we do not believe it will have a material impact on our future financial statements.
	In May 2014, the FASB issued new authoritative literature, Revenue from Contracts with Customers, which supersedes much of the existing authoritative literature for revenue recognition. This guidance will be effective January 1, 2017. We are currently evaluating the newly issued guidance and the impact on our future financial statements.

INVENTORIES	'
	INVENTORIES
	About 50% of our inventories are valued using the Last-In, First-Out (LIFO) cost method and the remainder using the First-In, First-Out (FIFO) cost method.
	We calculate our LIFO reserve (the excess of FIFO cost over LIFO cost) on an annual basis. During interim periods, we estimate the current year annual change in the LIFO reserve (i.e., the annual LIFO expense or benefit) and allocate that change ratably to the four quarters. Because accurately predicting inventory prices for the year is difficult, the change in the LIFO reserve for the full year could be significantly different from the amount currently estimated. In addition, a variation in expected ending inventory levels could also impact total change in the LIFO reserve for the year. Any change in the annual LIFO estimate will be reflected in the fourth quarter.
	The following table contains the LIFO (expense) benefit included in continuing operations for each of the periods presented.

Segment Reporting [Abstract]	'
SEGMENT INFORMATION	'
	SEGMENT INFORMATION
	We have four operating segments that supply a wide range of products:
	•	Residential Furnishings—components for bedding, furniture and other furnishings, as well as related consumer products
	•	Commercial Fixturing & Components—components for office and institutional furnishings
	•	Industrial Materials—drawn steel wire, specialty wire products, titanium and nickel tubing for the aerospace industry and welded steel tubing
	•	Specialized Products—automotive seating components, specialized machinery and equipment, and commercial vehicle interiors
	Our reportable segments are the same as our operating segments, which correspond with our management organizational structure. Each reportable segment has a senior operating vice-president that reports to the chief operating officer. The chief operating officer in turn reports directly to the chief operating decision maker. The operating results and financial information reported through the segment structure are regularly reviewed and used by the chief operating decision maker to evaluate segment performance, allocate overall resources and determine management incentive compensation.
	Separately, we also utilize a role-based approach (Grow, Core, Fix or Divest) as a supplemental management tool to ensure capital (which is a subset of the overall resources referred to above) is efficiently allocated within the reportable segment structure.
	The accounting principles used in the preparation of the segment information are the same as those used for the consolidated financial statements, except that the segment assets and income reflect the FIFO basis of accounting for inventory. Certain inventories are accounted for using the LIFO basis in the consolidated financial statements. We evaluate performance based on earnings from operations before interest and income taxes (EBIT). Intersegment sales are made primarily at prices that approximate market-based selling prices. Centrally incurred costs are allocated to the segments based on estimates of services used by the segment. Certain of our general and administrative costs and miscellaneous corporate income and expenses are allocated to the segments based on sales. These allocated corporate costs include depreciation and other costs and income related to assets that are not allocated or otherwise included in the segment assets.
	A summary of segment results from continuing operations are shown in the following tables.

DISCONTINUED OPERATIONS	'
	DISCONTINUED OPERATIONS
	During 2014 we engaged an investment banker and began exploring strategic alternatives regarding the Store Fixtures reporting unit, including the possibility of divestiture of this business. During the third quarter of 2014, all of the criteria to classify this unit as held for sale and discontinued operations were met. On November 1, 2014, we sold the majority of the Store Fixtures reporting unit for total consideration of approximately $62. At this price, we expect to record an after-tax loss of approximately $6 in the fourth quarter, which will be recognized in Discontinued Operations. We continue to pursue the sale of the remaining portion of the reporting unit. Store Fixtures was previously part of the Commercial Fixturing and Components Segment and has been classified as discontinued operations, net of income taxes, in the Consolidated Statements of Operations for all periods presented. The footnotes have been retrospectively adjusted to present the information for continuing operations only, unless otherwise noted.
	In the second quarter of 2013 we exited three small operations:
	•	We closed our final location that produced wire dishwasher racks, thereby discontinuing that line of business. This operation, which was previously in our Industrial Materials segment, was part of a restructuring plan that began in the
	fourth quarter of 2011. Tax benefits related to this business were recorded in the second quarters of both 2012 and 2013.
	•	We divested the specialty trailers portion of the Commercial Vehicle Products (CVP) Unit. This branch was previously part of the Specialized Products segment. No significant gains or losses were realized on the sale of this business.
	•	We closed a cotton-based erosion control products operation that was previously part of the Industrial Materials Segment. Charges of $1.9 were recorded in the second quarter of 2013 to reflect estimates of fair value less
	costs to sell, including $1.5 of fixed asset impairments as discussed in Note 6.
	The table below includes activity related to these operations:
		Nine Months Ended September 30,						Three Months Ended September 30,

	(1) This includes goodwill impairment charges of $108.0 in the second quarter of 2014 as discussed in Note 6.
	(2) Subsequent activity for businesses divested in prior years has been reported as discontinued operations in the table above, including a third quarter 2014 antitrust litigation settlement of $8.3 associated with our former Prime Foam Products unit as discussed in Note 15. This unit was sold in March 2007 and was previously a part of the Residential Furnishings segment.
	(3) The 2014 tax benefit is primarily related to the Store Fixtures goodwill impairment and the Prime Foam litigation settlement. The 2013 tax benefit is primarily related to a worthless stock deduction associated with the subsidiary that produced wire dishwasher racks.

	Other Long-Lived Assets
	We test other long-lived assets for recoverability at year end and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Fair value and the resulting impairment charges noted above were based primarily upon offers from potential buyers or third party estimates of fair value less selling costs.
	Goodwill
	Goodwill is required to be tested for impairment at least once a year and as triggering events may occur. We perform our annual goodwill impairment review in the second quarter of each year.
	Fair value of reporting units is determined using a combination of two valuation methods: a market approach and an income approach. Each method is generally given equal weight in determining the fair value assigned to each reporting unit. Absent an indication of fair value from a potential buyer or similar specific transaction, we believe that the use of these two methods provides a reasonable estimate of a reporting unit’s fair value. Assumptions common to both methods are operating plans and economic projections, which are used to project future revenues, earnings, and after-tax cash flows for each reporting unit. These assumptions are applied consistently for both methods.
	The market approach estimates fair value by first determining price-to-earnings ratios for comparable publicly-traded companies with similar characteristics of the reporting unit. The price-to-earnings ratio for comparable companies is based upon current enterprise value compared to projected earnings for the next two years. The enterprise value is based upon current market capitalization and includes a 25% control premium. Projected earnings are based upon market analysts’ projections. The earnings ratios are applied to the projected earnings of the comparable reporting unit to estimate fair value. Management believes this approach is appropriate because it provides a fair value estimate using multiples from entities with operations and economic characteristics comparable to our reporting units.
	The income approach is based on projected future (debt-free) cash flow that is discounted to present value using factors that consider the timing and risk of future cash flows. Management believes that this approach is appropriate because it provides a fair value estimate based upon the reporting unit’s expected long-term operating cash flow performance. Discounted cash flow projections are based on 10-year financial forecasts developed from operating plans and economic projections noted above, sales
	growth, estimates of future expected changes in operating margins, terminal value growth rates, future capital expenditures and changes in working capital requirements.
	If a triggering event occurs, special consideration is given to the new circumstances when determining the fair value of the impacted reporting unit.
	Goodwill Impairment Reviews
	We performed our annual goodwill impairment review in June 2014, and on July 14, 2014, concluded that a goodwill impairment charge was required for one reporting unit, Store Fixtures which is now recorded as discontinued operations, and was previously part of the Commercial Fixturing and Components segment.
	The Store Fixtures reporting unit is dependent upon capital spending by retailers on both new stores and remodeling of existing stores. Because of the seasonal nature of the fixture & display industry (where revenue and profitability are typically expected to increase in the second and third quarters assuming the normal historical pattern of heavy shipments during these months) we reasonably anticipated being awarded significant customer orders in the second quarter of 2014. However, as the second quarter progressed, anticipated orders did not materialize and the Store Fixtures business deteriorated, with declines most pronounced in May and June. Taking these recent developments into account, we lowered our projection of future margins and growth rates (from 4.8% in prior year's review to .5% in the current year for 10-year compound annual growth rate for EBIT plus depreciation and amortization) and increased the discount rate from 10.5% to 12%, causing fair value to fall below carrying value. The lower expectations of future revenue and profitability are due to reduced overall market demand for the shelving, counters, showcases and garment racks as many retailers are reducing their investments in traditional store space and focusing more on e-commerce initiatives.
	Because the fair value of the Store Fixtures reporting unit had fallen below recorded book values, we performed the second step of the test which requires a fair value assessment of all assets and liabilities of the reporting unit to calculate an implied goodwill amount. This resulted in a $108.0 goodwill impairment charge that was recorded in the second quarter of 2014. This charge reflects the complete impairment of all goodwill associated with the Store Fixtures reporting unit.
	As a result of the above, we also determined a triggering event had occurred in the second quarter to test other long-lived assets which were evaluated for impairment under the held for use model. No long-lived asset impairments (excluding goodwill) were indicated during this review. During the third quarter of 2014, all of the criteria to classify this unit as held for sale and discontinued operations were met as discussed in Note 5.
	The fair values of reporting units in relation to their respective carrying values and significant assumptions used in the June 2014 review are presented in the table below. The information below excludes Store Fixtures, as this unit had no goodwill remaining after the second quarter 2014 impairment.

	-1	Stock Option Grants
	Historically we have granted stock options in the following areas:
	•	On a discretionary basis to a broad group of employees
	•	In conjunction with our Deferred Compensation Program
	•	As compensation of outside directors
	Starting in 2013, we discontinued the broad annual option grant, and options are now offered only in conjunction with the Deferred Compensation Program discussed below, and were replaced with either cash awards or RSUs. Certain key management employees participated in a new Profitable Growth Incentive (PGI) program beginning in 2013, as discussed below.
	Deferred Compensation Program
	We offer a Deferred Compensation Program under which key managers and outside directors may elect to receive stock options, stock units or interest-bearing cash deferrals in lieu of cash compensation:
	•	Stock options under this program are granted on the last business day of the year prior to the year the compensation is earned. The number of options granted equals the deferred compensation times five, divided by the stock’s market price on the date of grant. The option has a 10-year term. It vests as the associated compensation is earned and becomes exercisable beginning 15 months after the grant date. Stock is issued when the option is exercised.
	•	Deferred stock units (DSU) under this program are acquired every two weeks (when the compensation would have otherwise been paid) at a 20% discount to the market price of our common stock on each acquisition date and they vest immediately. Expense is recorded as the compensation is earned. Stock units earn dividends at the same rate as cash dividends paid on our common stock. These dividends are used to acquire stock units at a 20% discount. Stock units are converted to common stock and distributed in accordance with the participant’s pre-set election. However, stock units may be settled in cash at the discretion of the Company. Participants must begin receiving distributions no later than ten years after the effective date of the deferral and installment distributions cannot exceed ten years.
	•	Interest-bearing cash deferrals under this program are reported in Other long-term liabilities on the balance sheet.
	(2) Stock-Based Retirement Plans
	We have two stock-based retirement plans: the tax-qualified Stock Bonus Plan (SBP) for non-highly compensated employees, and the non-qualified Executive Stock Unit Program (ESUP) for highly compensated employees. We make matching contributions to both plans. In addition to the automatic 50% match, we will make another matching contribution of up to 50% of the employee’s contributions for the year if certain profitability levels, as defined in the SBP and the ESUP, are obtained. Company contributions to the ESUP, including dividend equivalents, are used to acquire stock units at 85% of the common stock market price on the acquisition date. Participant contributions to the ESUP are credited to a diversified investment account established for the participant and we make premium contributions to the diversified investment accounts equal to 17.5% of the participant's contribution.
	(3) Performance Stock Unit Awards
	We grant Performance Stock Unit (PSU) awards in the first quarter of each year to selected officers and other key managers. These awards contain the following conditions:
	•	A service requirement—Awards generally “cliff” vest three years following the grant date; and
	•	A market condition—Awards are based on our Total Shareholder Return [TSR =Change in Stock Price + Dividends) / Beginning Stock Price] as compared to the TSR of a group of peer companies. The peer group consists of all the companies in the Industrial, Materials and Consumer Discretionary sectors of the S&P 500 and S&P Midcap 400 (approximately 320 companies). Participants will earn from 0% to 175% of the base award depending upon how our Total Shareholder Return ranks within the peer group at the end of the 3-year performance period.
	Grant date fair values are calculated using a Monte Carlo simulation of stock and volatility data for Leggett and each of the comparator companies. Grant date fair values are amortized using the straight-line method over the three-year vesting period.
	Below is a summary of the number of shares and related grant date fair value of PSU’s for the periods presented

The above information represents the 65% portion of the award that was settled in shares of our common stock. For outstanding awards, we intend to pay 65% in shares of our common stock, although we reserve the right to pay up to 100% in cash. The additional amount that represents 35% of the award will be settled in cash, and is recorded as a liability and adjusted to fair value at each reporting period.
(4) Restricted Stock Unit Awards
RSU awards are generally granted as follows:
•	To managers in lieu of annual option grants
•	On a discretionary basis to selected managers
•	To selected executive officers in connection with employment agreements
•	As compensation for outside directors, who have a choice to receive RSUs or restricted stock
The value of these awards is determined by the stock price on the day of the award, and expense is recognized over the vesting period.
(5) Profitable Growth Incentive Awards
Starting in 2013, certain key management employees participated in a new Profitable Growth Incentive (PGI) program in lieu of the annual option grant. The PGI awards are issued as growth performance stock units (GPSUs). The GPSUs vest (0% to 250%) at the end of a two-year performance period. Vesting is based on the Company's or applicable profit center's revenue growth (adjusted by a GDP factor when applicable) and EBITDA margin at the end of a two-year performance period. The 2014 and 2013 base target PGI awards were each .1 shares. If earned, we intend to pay half in shares of our common stock and half in cash, although we reserve the right to pay up to 100% in cash. Both components are adjusted to fair value at each reporting period.
(6) Discount Stock Plan
Under the Discount Stock Plan (DSP), a tax-qualified §423 stock purchase plan, eligible employees may purchase shares of Leggett common stock at 85% of the closing market price on the last business day of each month. Shares are purchased and issued on the last business day of each month and generally cannot be sold or transferred for one year.

	30-Sep-13		3		Industrial Materials (2); Specialized Products (1)		Tubing for the aerospace industry (2); Innerspring unit wire-forming machines
	On June 30, 2014, we acquired Tempur Sealy's three U.S. innerspring component production facilities for a purchase price of $45.7 million. Factors contributing to the recognition of $15.6 million in goodwill from the acquisition included: additional production that enhances economies of scale; benefits from our vertical integration in steel rod and wire; and the optimization of manufacturing across a broad asset base.
	In 2013 we expanded our Aerospace Products business unit with the acquisition of two companies:
	The first was a UK-based business that extended our capability in aerospace tube fabrication. This business was acquired for a purchase price of $11.7, and $6.1 of goodwill was recorded related to this acquisition. Factors that contributed to a purchase price resulting in the recognition of goodwill included its international presence and complimentary fit with our Aerospace Products business unit. The second was a French-based company that added small-diameter, high-pressure seamless tubing to our product portfolio for a cash purchase price of $14.5. This business was acquired at a price less than fair value of the net identifiable assets, and we recorded an $8.7 non-taxable bargain purchase
	gain. The bargain purchase gain is reported in the "Other (income) expense, net" line of our income statement. Prior to recognizing a bargain purchase gain, we reassessed whether all assets acquired and liabilities assumed had been correctly identified, the key valuation assumptions and business combination accounting procedures for this acquisition. After careful consideration and review, we concluded that the recognition of a bargain purchase gain was appropriate for this acquisition. Factors that contributed to the bargain purchase price were:
	• The transaction was completed with a motivated seller that desired to restructure its operations
	in order to focus on its core competencies and exit non-core businesses that no longer fit its
	strategy in an expedient manner.
	• We were able to complete the acquisition with a cash payment and without a financial contingency
	in an expedient manner, which was a key attribute for the seller. The relatively small size of the
	transaction for us, the lack of required third-party financing and our expertise in completing
	similar transactions in the past gave the seller confidence that we could complete the transaction
	quickly and without difficultly.
	• Because the seller of this business will continue to purchase these products in the future it was
	important to the seller that the acquiring company was a financially sound, integrated
	manufacturer that could provide a stable supply of high quality product for many years into the
	future. Due to the unique nature of the products and limited number of potential buyers for this
	business, the seller found it advantageous to accept our purchase price based upon our
	demonstrated ability to operate similar businesses, and financial strength that will enable us to
	be a long-term supplier of quality products into the future.
	In addition, in the third quarter of 2012, we invested $22.4 to acquire an interest in an unconsolidated entity related to a potential acquisition. We had no contractual right or obligation to make any additional investment and liquidated our position in the 3rd quarter of 2013 for $21.2, plus $1.8 in interest.
	The results of operations of the above acquired companies have been included in the consolidated financial statements since the dates of acquisition. The unaudited pro forma consolidated net sales, net earnings and earnings per share as though the 2014 and 2013 acquisitions had occurred on January 1 of each year presented are not materially different from the amounts reflected in the accompanying financial statements. Certain of our acquisition agreements provide for additional consideration to be paid in cash at a later date and are recorded as a liability at the acquisition date. At September 30, 2014, there was no substantial remaining consideration payable.

Fair Value Disclosures [Abstract]	'
FAIR VALUE	'
	FAIR VALUE
	We utilize fair value measures for both financial and non-financial assets and liabilities.
	Items measured at fair value on a recurring basis
	The areas in which we utilize fair value measures of financial assets and liabilities are presented in the table below.
	Fair value measurements are established using a three level valuation hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into the following categories:
	•	Level 1: Quoted prices for identical assets or liabilities in active markets.
	•	Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly. Short-term investments in this category are valued using discounted cash flow techniques with all significant inputs derived from or corroborated by observable market data. Derivative assets and liabilities in this category are valued using models that consider various assumptions and information from market-corroborated sources. The models used are primarily industry-standard models that consider items such as quoted prices, market interest rate curves applicable to the instruments being valued as of the end of each period, discounted cash flows, volatility factors, current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.
	•	Level 3: Unobservable inputs that are not corroborated by market data.

	* - Includes both current and long-term amounts combined.
	There were no transfers between Level 1 and Level 2 for any of the periods presented.
	The fair value for fixed rate debt (Level 2) was greater than its $830 carrying value by $7 at September 30, 2014 and $3 less than its $830 carrying value at December 31, 2013. We value this debt using discounted cash flow and secondary market rates provided by Bloomberg.
	Items measured at fair value on a non-recurring basis
	The primary areas in which we use fair value measurements of non-financial assets and liabilities are allocating purchase price to the assets and liabilities of acquired companies as discussed in Note 10, and evaluating long-term assets (including goodwill) for potential impairment as discussed in Note 6. Determination of fair values for these items requires significant judgment and are calculated utilizing a variety of methods and models that utilize significant Level 3 inputs.
	Long lived assets, acquisitions and the second step of a goodwill impairment test utilize the following methodologies in determining fair value: (i) Buildings and machinery are valued at an estimated replacement cost for an asset of comparable age and condition. Market pricing of comparable assets is used to estimate replacement cost where available. (ii) The most common identified intangible assets are customer relationships and tradenames. Customer relationships are valued using an excess earnings method, using various inputs such as the estimated customer attrition rate, future earnings forecast,  the amount of contributory asset charges, and a discount rate. Tradenames are valued  using a relief from royalty method, which is based upon comparable market royalty rates for tradenames of similar value. (iii) Inventory is valued at current replacement cost for raw materials, with a step-up for work in process and finished goods items that reflects the amount of ultimate profit earned as of the valuation date. (iv) Other working capital items are generally recorded at face value, unless there are known conditions that would impact the ultimate settlement amount of the particular item.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
RISK MANAGEMENT AND DERIVATIVE FINANCIAL INSTRUMENTS	'
	RISK MANAGEMENT AND DERIVATIVE FINANCIAL INSTRUMENTS
	Risk Management Strategy & Objectives
	We are subject to market and financial risks related to interest rates, foreign currency, and commodities. In the normal course of business, we utilize derivative instruments (individually or in combinations) to manage these risks. We seek to use derivative contracts that qualify for hedge accounting treatment; however, some instruments may not qualify for this treatment. It is our policy not to speculate using derivative instruments.
	Cash Flow Hedges
	Derivative financial instruments that we use to hedge forecasted transactions and anticipated cash flows are as follows:
	•	Commodity Cash Flow Hedges—We have historically used commodity cash flow hedges primarily to manage natural gas commodity price risk. Our last natural gas commodity hedge expired during 2013.
	•	Interest Rate Cash Flow Hedges -
	In August 2012, we issued $300 of 10-year notes with a coupon rate of 3.4%. As a part of this transaction, we settled our $200 forward starting interest rate swaps we had entered into during 2010 and recognized a loss of $42.7, which will be amortized out of accumulated other comprehensive income to interest expense over the life of the notes.
	In anticipation of the maturity of our $180 million 4.65% Senior Notes due November 2014, we entered into a treasury lock agreement in October 2014. The treasury lock manages benchmark treasury interest rate risk associated with $50 million of future debt and will be settled at the earlier of November 12, 2014 or upon the issuance of debt. The treasury lock has an interest rate of 2.36%. The settlement of the treasury lock is not expected to result in a material gain or loss. We are evaluating financing alternatives for the retirement of the 4.65% Senior Notes, which may include accessing the capital markets, and believe that we have available sources of funds to satisfy this obligation, as well as support our ongoing operations, pay dividends, fund future growth, and repurchase stock.
	•	Currency Cash Flow Hedges—The foreign currency hedges manage risk associated with exchange rate volatility of various currencies.
	The effective changes in fair value of unexpired contracts are recorded in accumulated other comprehensive income and reclassified to income or expense in the period in which earnings are impacted. Cash flows from settled contracts are presented in the category consistent with the nature of the item being hedged. (Settlements associated with the sale or production of product are presented in operating cash flows and settlements associated with debt issuance are presented in financing cash flows.)
	Fair Value Hedges
	Our fair value hedges typically manage foreign currency risk associated with subsidiaries’ inter-company assets and liabilities. Hedges designated as fair value hedges recognize gain or loss currently in earnings. Cash flows from settled contracts are presented in the category consistent with the nature of the item being hedged.
	Hedge Effectiveness
	We have deemed ineffectiveness to be immaterial, and as a result, have not recorded any amounts for ineffectiveness. If a hedge was not highly effective, the portion of the change in fair value considered to be ineffective would be recognized immediately in the consolidated statements of operations.
	We have recorded the following assets and liabilities representing the fair value for our most significant derivative financial instruments. The fair values of the derivatives reflect the change in the market value of the derivative from the date of the trade execution, and do not consider the offsetting underlying hedged item.

	CONTINGENCIES
	We are a defendant in various proceedings involving employment, antitrust, intellectual property, environmental, taxation and other laws. When it is probable, in management’s judgment, that we may incur monetary damages or other costs resulting from these proceedings or other claims, and we can reasonably estimate the amounts, we record appropriate liabilities in the financial statements and make charges against earnings. For all periods presented, we have recorded no material charges against earnings other than as indicated below, and the total liabilities recorded are not material to our financial position.
	Shareholder Derivative Lawsuit
	On August 10, 2010, a shareholder derivative suit was filed by the New England Carpenters Pension Fund in the Circuit Court of Jasper County, Missouri as Case No. 10AO-CC284. The suit was purportedly brought on our behalf, naming us as a nominal defendant, and certain current and former officers and directors as individual defendants including David S. Haffner, Karl G. Glassman, Matthew C. Flanigan, Ernest C. Jett, Harry M. Cornell, Jr., Felix E. Wright, Robert Ted Enloe, III, Richard T. Fisher, Judy C. Odom, Maurice E. Purnell, Jr., Ralph W. Clark and Michael A. Glauber. The plaintiff alleged, among other things, that the individual defendants: breached their fiduciary duties; backdated and received backdated stock options violating our stock plans; caused or allowed us to issue false and misleading financial statements and proxy statements; sold our stock while possessing material non-public information; committed gross mismanagement; wasted corporate assets; committed fraud; violated the Missouri Securities Act; and were unjustly enriched.
	The plaintiff was seeking, among other things: unspecified monetary damages against the individual defendants; certain equitable and other relief relating to the profits from the alleged improper conduct; the adoption of certain corporate governance proposals; the imposition of a constructive trust over the defendants’ stock options and proceeds; punitive damages; the rescission of certain unexercised options; and the reimbursement of litigation costs. The plaintiff was not seeking monetary relief from us. We have director and officer liability insurance in force subject to customary limits and exclusions.
	We and the individual defendants filed motions to dismiss the suit in late October 2010, asserting: the plaintiff failed to make demand on our Board and shareholders as required by Missouri law, and this failure to make demand should not be excused; the dismissal of the substantially similar suit in 2009 precludes the 2010 suit; the plaintiff is not a representative shareholder; the suit was based on a statistical analysis of stock option grants and our stock prices that we believe was flawed; the plaintiff failed to state a substantive claim; the common law fraud claim was not pled with sufficient particularity; and the statute of limitations has expired on the fraud claim and all the alleged challenged grants except the December 30, 2005 grant. As to this grant, the motions to dismiss advised the Court that it was made under our Deferred Compensation Program, which (i) provided that options would be dated on the last business day of December, and (ii) was filed with the SEC on December 2, 2005 setting out the pricing mechanism well before the grant date. On April 6, 2011, the suit was dismissed without prejudice.
	On May 12, 2011, the plaintiff filed an appeal to the Missouri Court of Appeals. On November 28, 2012, the Missouri Court of Appeals reversed the trial court's dismissal finding that plaintiff sufficiently pleaded it would be futile
	to make demand on the Board and shareholders. The Court of Appeals did not address the other grounds that had been raised in the motions to dismiss. We filed a request for transfer to the Missouri Supreme Court on December 12, 2012, which was denied by the Court of Appeals. On January 3, 2013, we filed a transfer petition to the Missouri Supreme Court. On February 26, 2013, the Missouri Supreme Court denied our request. The case was sent back to Jasper County, Missouri for further proceedings. At the parties' request, on June 4, 2013, the circuit court stayed all proceedings to allow the parties to mediate the dispute.
	Settlement of the Shareholder Derivative Case. On May 12, 2014, the defendants, denying all wrongdoing and liability, entered into a Stipulation of Settlement whereby the Company would pay $2.9 for plaintiff counsel fees and costs and agree to certain Corporate Governance Measures in exchange for a complete release of all claims against all defendants. The Corporate Governance Measures include the continued maintenance, for a minimum of three years, of: (i) annual stock option grant dates to be pre-determined and fixed; (ii) plan documents to define the stock option exercise price, the grant date and the fair market value of the stock or the formula for determining such amount; (iii) the exercise price for each option to be 100% of the closing price on the grant date or the average closing market price on a range of dates; (iv) grant dates to be no earlier than the date the Board or Compensation Committee (or delegated committee for non-Section 16 officers) makes the determination granting such options; (v) all plans to comply with legal disclosure and accounting requirements; (vi) effective monitoring mechanisms for the timely and accurate filing of SEC Forms 3, 4 and 5; (vii) a majority of independent directors; (viii) the grants to Section 16 officers to be made at Board or Compensation Committee meetings; (ix) written documentation identifying all grantees, amounts and prices of stock options granted to be complete and final on the grant date and signed by the CEO or CLO; (x) training programs that address executive compensation, governance, and the requirements of our stock option plans; (xi) an annual message by the CEO to salaried employees regarding the importance of the compliance culture; (xii) annual reports to the Board or Audit Committee by the CLO or General Counsel on the status of corporate compliance; (xiii) the Company whistle blower program in compliance with law; and (xiv) an internal Audit Department approved by the Audit Committee with a Vice President of Internal Audit with adequate credentials and a direct reporting relationship to the Audit Committee.
	The Court entered an order preliminarily approving the Stipulation of Settlement on June 4, 2014. Upon the Court’s preliminary approval the Company (i) filed the notice of settlement on Form 8-K on June 10, 2014; (ii) posted the notice on the Company’s website on the same date; and (iii) published the notice in the Investor’s Business Daily on June 12, 2014. A hearing was held on September 4, 2014 at which time the Court approved the final Settlement. In the third quarter of 2014, we paid $.7 in attorney's fees while $2.2 was paid by our insurance carrier.
	Antitrust Lawsuits
	Beginning in August 2010, a series of civil lawsuits was initiated in several U.S. federal courts and in Canada against over 20 defendants alleging that competitors of our carpet underlay business unit and other manufacturers of polyurethane foam products had engaged in price fixing in violation of U.S. and Canadian antitrust laws.
	U.S. Direct Purchaser Class Action Cases. We have been named as a defendant in three pending direct purchaser class action cases (the first on November 15, 2010) on behalf of a class of all direct purchasers of polyurethane foam products. The direct purchaser class action cases were all filed in or were transferred to the U.S. District Court for the Northern District of Ohio under the name In re: Polyurethane Foam Antitrust Litigation, Case No. 1:10-MD-2196.
	The plaintiffs, on behalf of themselves and/or a class of direct purchasers, seek three times the amount of damages allegedly suffered as a result of alleged overcharges in the price of polyurethane foam products from at least 1999 to the present. Each plaintiff also seeks attorney fees, pre-judgment and post-judgment interest, court costs, and injunctive relief
	against future violations. On April 15 and May 6, 2011, we filed motions to dismiss the U.S. direct purchaser class actions in the consolidated case in Ohio, for failure to state a legally valid claim. On July 19, 2011, the Ohio Court denied the motions to dismiss. A motion for class certification was filed on behalf of the direct purchasers. A hearing on the motion was held January 15, 2014. On April 9, 2014, the Court certified the direct purchaser class. We filed a Petition for Permission to Appeal from Class Certification Order to the United States Court of Appeals for the Sixth Circuit on April 23, 2014. The petition to appeal was denied on September 29, 2014. The Court ordered all parties to attend non-binding mediation with a mediator of their choosing.
	Settlement of U.S. Direct Purchaser Class Action Cases. We reached a tentative settlement in the U.S. direct purchaser class action cases on August 14, 2014, by agreeing to pay an aggregate amount of $39.8, inclusive of plaintiff attorneys' fees and costs. We continue to deny all allegations in the cases, but settled the direct purchaser class cases to avoid the risk, uncertainty, expense and distraction of the litigation. The settlement is subject to Court approval. We recorded a $39.8 (pre-tax) accrual for the settlement in the third quarter 2014. Since the payment would be partially attributable to our former Prime Foam Products business, which was sold in the first quarter of 2007, $8.3 is reflected in discontinued operations.
	U.S. Indirect Purchaser Class Action Cases. We were named as a defendant (but not served with process) in an indirect purchaser class consolidated amended complaint filed on March 21, 2011 and subsequently sued in an indirect purchaser class action case filed on May 23, 2011, in the U.S. District Court for the Northern District of Ohio that proceeds under the name In re: Polyurethane Foam Antitrust Litigation, Case No. 1:10-MD-2196. The plaintiffs, on behalf of themselves and/or a class of indirect purchasers, bring damages claims under various states’ antitrust and consumer protection statutes, and are seeking three times an amount of damages allegedly suffered as a result of alleged overcharges in the price of polyurethane foam products from at least 1999 to the present. Each plaintiff also seeks attorney fees, pre-judgment and post-judgment interest, court costs, and injunctive relief against future violations. On April 15 and May 6, 2011, we filed motions to dismiss the indirect purchaser class action, for failure to state a legally valid claim. On July 19, 2011, the Ohio Court denied the motions to dismiss. Discovery is nearing completion in the indirect purchaser class case. A motion for class certification was filed on behalf of the indirect purchasers. A hearing on the motion was held January 15, 2014. On April 9, 2014, the Court certified the indirect purchaser class. We filed a Petition for Permission to Appeal from Class Certification Order to the United States Court of Appeals for the Sixth Circuit on April 23, 2014. The petition to appeal was denied on September 29, 2014. The Court ordered all parties to attend non-binding mediation with a mediator of their choosing. The trial date for the indirect purchaser class cases is tentatively set for 2015.
	U.S. Individual Direct Purchaser Cases. We have been named as a defendant in 38 individual direct purchaser cases filed between March 22, 2011 and October 16, 2013, which were filed in or transferred to the U.S. District Court for the Northern District of Ohio under the name In re: Polyurethane Foam Antitrust Litigation, Case No. 1:10-MD-2196. The claims in the individual direct purchaser cases are generally the same as those asserted in the direct purchaser class action cases, with the exception of one case that also alleges an indirect purchaser claim. Additionally, several individual direct purchaser plaintiffs bring state claims under individual states’ consumer protection and/or antitrust statutes in addition to their federal claims. Once pretrial practice concludes, some of the individual direct purchaser cases are scheduled to be tried in the U.S. District Court for the Northern District of Ohio and others will be remanded back to the federal district courts where the cases were originally filed for trial.
	Kansas Restraint of Trade Act Cases. We have been named as defendants in two individual cases alleging direct and indirect purchaser claims under the Kansas Restraint of Trade Act, one filed on November 29, 2012 and the other on April 11, 2013. These two cases were filed in the U.S. District Court for the District of Kansas and then transferred to the U.S. District Court for the Northern District of Ohio under the name In re: Polyurethane Foam Antitrust Litigation, Case No. 1:10-MD-2196. The claims and allegations of these plaintiffs are generally the same as the other direct and indirect purchaser plaintiffs, with the exception that the Kansas plaintiffs seek full consideration damages (their total purchase amounts for the allegedly price-fixed polyurethane foam products). Once pretrial practice concludes, this case will be remanded back to the District of Kansas federal district court for trial.
	Canadian Class Action Cases. We have been named in two Canadian class action cases (for direct and indirect purchasers of polyurethane foam products), both under the name Hi Neighbor Floor Covering Co. Limited and Hickory Springs Manufacturing Company, et.al. in the Ontario Superior Court of Justice (Windsor), Court File Nos. CV-10-15164 (amended November 2, 2011) and CV-11-17279 (issued December 30, 2011). In each of the Canadian cases, the plaintiffs, on behalf of themselves and/or a class of purchasers, seek from over 13 defendants restitution of the amount allegedly overcharged, general and special damages in the amount of $100, punitive damages of $10, pre-judgment and post-judgment interest, and the costs of the investigation and the action. The first issued class action is on behalf of a class of purchasers of polyurethane foam. The second issued class action is on behalf of purchasers of carpet underlay. We are not yet required to file our defenses in these or any other Canadian actions. In addition, on July 10, 2012, plaintiff in a class action case (for direct and indirect purchasers of polyurethane foam products) styled Option Consommateurs and Karine Robillard v. Produits Vitafoam Canada Limitée, et. al. in the Quebec Superior Court of Justice (Montréal), Court File No. 500-6-524-104, filed an amended motion for authorization seeking to add us and other manufacturers of polyurethane foam products as defendants in this case, which was granted. This action has a pending motion for certification which is to be heard in January 2015. We also were notified in June 2014 of two motions to add us as parties to two class proceedings in British Columbia. Those proceedings are similar to the Ontario proceedings in that one proposes a class of purchasers of polyurethane foam (Majestic Mattress Mfg. Ltd. v. Vitafoam Products et al., No. VLC-S-S-106362 Vancouver Registry) and one proposes a class of purchasers of carpet underlay (Trillium Project Management Ltd. v. Hickory Springs Manufacturing Company et al., No.S106213 Vancouver Registry). The motion to add us as parties to these actions has been scheduled to be heard with the motions for certification in the two actions in April 2015. The British Columbia actions involve British Columbia purchasers only whereas the Ontario actions propose classes of Canadian purchasers. No certification motions will be brought in the Ontario actions until after the British Columbia motions for certification have been determined.
	Missouri Class Action Case. On June 22, 2012, we were also made a party to a lawsuit brought in the 16th Judicial Circuit Court, Jackson County, Missouri, Case Number 1216-CV15179 under the caption “Dennis Baker, on Behalf of Himself and all Others Similarly Situated vs. Leggett & Platt, Incorporated.” The plaintiff, on behalf of himself and/or a class of indirect purchasers of polyurethane foam products in the State of Missouri, alleged that we violated the Missouri Merchandising Practices Act based upon our alleged illegal price inflation of flexible polyurethane foam products. The plaintiff seeks unspecified actual damages, punitive damages and the recovery of reasonable attorney fees. We filed a motion to dismiss this action, which was denied on November 5, 2012. Discovery has commenced and plaintiff has filed a motion for class certification. The parties' briefing is completed, and a hearing on the motion was held on February 20, 2014.
	We deny all of the allegations in all of the above actions and will vigorously defend ourselves. These contingencies are subject to many uncertainties. Therefore, because of the complexity involved in the above cases, and based on the information available to date, and because the litigation involves unsettled legal theories, we cannot reasonably estimate the amount or range of potential loss, if any.
	Brazilian Value-Added Tax Matters
	Brazilian Federal Cases. On December 22, 2011, the Brazilian Finance Ministry, Federal Revenue Office issued a notice of violation against our wholly-owned subsidiary, Leggett & Platt do Brasil Ltda. (“L&P Brazil”) in the amount of $3, under Case No. 10855.724660/2011-43. The Brazilian Revenue Office claimed that for the period beginning November 2006 and continuing through December 2007, L&P Brazil used an incorrect tariff code for the collection and payment of value-added tax primarily on the sale of mattress innerspring units in Brazil. L&P Brazil responded to the notice of violation on January 26, 2012 denying the violation. The Federal Revenue Office, on August 9, 2013, denied L&P Brazil’s defenses and upheld the assessment at the first administrative level. L&P Brazil filed an appeal on November 14, 2013. On December 29, 2011, L&P received another assessment in the amount of $.2, under case No. 10855.724509/2011-13 on the same subject matter in connection to certain import transactions carried out between 2007 and 2011. L&P filed its defense on February 2, 2012.
	On December 17, 2012, the Brazilian Revenue Office issued an additional notice of violation in the amount of $5.2 under MPF Case No. 10855.725260/2012-36 covering the period from January 1, 2008 through December 31, 2010 on the same subject matter. L&P Brazil responded to the notice of violation on January 17, 2013 denying the violation. The Brazilian Revenue Office, on June 13, 2013, denied L&P Brazil's defenses and upheld the assessment at the first administrative level. L&P Brazil appealed this decision on July 8, 2013. The Brazilian Revenue Office, on December 18, 2013, also issued an audit notice for years 2011 and 2012. On June 26, 2014, the Brazilian Revenue Office issued a new notice of violation against L&P Brazil in the amount of $1.0, under Case No. 10660.721523/2014-87, covering the period
	from 2011 through 2012 on the same subject matter as the other assessments. L&P Brazil filed its defense on August 5, 2014.
	In addition, L&P Brazil received assessments on December 22, 2011, and June 26, July 2 and November 5, 2012, and September 13, 2013 from the Brazilian Federal Revenue Office where the Revenue Office challenged L&P Brazil’s use of certain tax credits in the years 2006 through 2010. Such credits are generated based upon the tariff classification and rate used by L&P Brazil for value-added tax on the sale of mattress innersprings. On September 15, 2014, L&P Brazil received five additional assessments regarding this same issue, covering the period 2011 through 2012. L&P Brazil filed its defense to these assessments on October 13, 2014. Combined with the prior assessments, L&P Brazil has received assessments totaling $3.5 on the same or similar denial of tax credit matters.
	On February 1, 2013, the Brazilian Finance Ministry filed a Tax Collection action against L&P Brazil in the Camanducaia Judicial District Court, Case No. 0002222-35.2013.8.13.0878, alleging the untimely payment of $.2 of social contributions (social security and social assistance payments) for the period September to October 2010. L&P Brazil filed its response, a Motion to Stay of Execution, on July 11, 2013. L&P Brazil argued the payments were not required to be made because of the application of certain tax credits that were generated by L&P Brazil's use of a correct tariff code for the classification of value-added tax on the sale of mattress innersprings (i.e., the same underlying issue at stake in the other Brazilian matters).
	On July 17, 2014, the Brazilian Finance Ministry rendered a preliminary decision to reject certain offsetting requests presented by L&P Brazil, which originated with Administrative Proceeding No. 10660.720850/2014-11. The Brazilian Finance Ministry alleges that L&P Brazil improperly offset $.2 of social contributions otherwise due in 2011. L&P Brazil filed its response on August 5, 2014, denying the allegations. L&P Brazil is defending on the basis that the social contribution debts were correctly offset with certain tax credits that were generated by L&P Brazil's use of a correct tariff code classification for value-added tax on the sale of mattress innersprings (i.e., the same underlying issue at stake in the other Federal Brazilian matters).
	On September 4, 2014, the Brazilian Federal Revenue issued an assessment against L&P Brazil in the amount of $.2, for the period of April 2011 through June 2012, as a penalty for L&P Brazil’s requests to offset certain tax credits. We filed our defense on October 16, 2014.
	State of Sao Paulo, Brazil Cases. L&P Brazil is party to a proceeding involving the State of Sao Paulo, Brazil where the State of Sao Paulo, on April 16, 2009, issued a Notice of Tax Assessment and Imposition of Fine to L&P Brazil seeking $2.3 for the tax years 2006 and 2007, under Case No. 3.111.006 (DRT n°.04-256.169/2009). The State of Sao Paulo argued that L&P Brazil was using an incorrect tariff code for the collection and payment of value-added tax on sales of mattress innerspring units in the State of Sao Paulo. On September 29, 2010, the Court of Tax and Fees of the State of Sao Paulo ruled in favor of L&P Brazil nullifying the tax assessment. The State filed a special appeal and the Special Appeals court remanded the case back to the Court of Tax and Fees for further findings. On November 9, 2012, the Court of Tax and Fees again ruled in favor of L&P Brazil and nullified the tax assessment. On November 28, 2012, the State filed another special appeal. The determination to accept the special appeal was made on December 26, 2012, and L&P Brazil responded to this special appeal on January 24, 2013. On April 17, 2014, the Court of Tax and Fees ruled in the State's favor upholding the original assessment of $2.3. On July 31, 2014, L&P Brazil filed an annulment action, Case No. 101712346.2014.8260602 in the Sorocaba State Court seeking to have the Court of Tax and Fees ruling annulled.
	On October 4, 2012, the State of Sao Paulo issued a Tax Assessment dated May 29, 2012 under Procedure Number 4.003.484 against L&P Brazil in the amount of $1.9 for the tax years 2009 through 2011. Similar to the 2009 assessment, the State of Sao Paulo argues that L&P Brazil was using an incorrect tax rate for the collection and payment of value-added tax on sales of mattress innerspring units in the State of Sao Paulo. On June 21, 2013, the State of Sao Paulo's attorneys converted the Tax Assessment No. 4.003.484 to a tax collection action against L&P Brazil in the amount of $2.5, under Sorocaba Judicial District Court, Case No. 3005528-50.2013.8.26.0602. L&P Brazil filed its response, a Motion to Stay of Execution, on January 27, 2014 denying the allegations.
	L&P Brazil also received a Notice of Tax Assessment and Imposition of a Fine from the State of Sao Paulo dated April 1, 2014, under Procedure Number 4.038.746-0 against L&P Brazil in the amount of $1.2 for the tax years January 2011 through August 2012 regarding the same subject matter. L&P filed its response on April 30, 2014, denying the allegations. On June 27, 2014, the first administrative level denied L&P Brazil’s defense and upheld the assessment. L&P Brazil filed its appeal of this decision on July 25, 2014.
	State of Minas Gerais, Brazil Cases. On December 18, 2012, the State of Minas Gerais, Brazil issued a tax assessment to L&P Brazil relating to L&P Brazil's classifications of innersprings for the collection and payment of value-added tax on the sale of mattress innersprings in Minas Gerais from March 1, 2008 through August 31, 2012 in the amount of $.6, under PTA Case No. 01.000.182756-62. L&P Brazil filed its response denying any violation on January 17, 2013. On October 22, 2013, the first administrative level ruled against us but did reduce the tax to $.3 (plus interest and penalties). We appealed to the second administrative level on December 30, 2013, which affirmed the first administrative level ruling. The case will now proceed judicially under Case No. 0003673-61.2014.8.13.0878 in Camanducaia Judicial District Court. L&P Brazil filed its response, a Motion to Stay of Execution, on June 5, 2014.
	We deny all of the allegations in all of the above actions. We believe that we have valid bases upon which to contest such actions and will vigorously defend ourselves. However, these contingencies are subject to many uncertainties.
	Patent Infringement Claim
	On January 24, 2012, in a case in the United States District Court for the Central District of California, the jury entered a verdict against us in the amount of $5 based upon an allegation by plaintiff that we infringed three patents on an automatic stapling machine and on methods used to assemble box springs. This action was originally filed on October 4, 2010, as case number CV10-7416 RGK (SSx) under the caption Imaginal Systematic, LLC v. Leggett & Platt, Incorporated; Simmons Bedding Company; and Does 1 through 10, inclusive. Leggett is contractually obligated to defend and indemnify Simmons Bedding Company against a claim for infringement.
	On summary judgment motions, we unsuccessfully disputed each patent’s validity and denied that we infringed any patent. At the jury trial on damages issues, the plaintiff alleged damages of $16.2. The court denied plaintiff’s attempt to win an attorney fee award and triple the pre-verdict damages.
	On April 9, 2012 we appealed the case to the Federal Circuit Court of Appeals. Oral argument was held on February 6, 2013 before a three judge appeal panel in the Federal Circuit in Washington D.C. On February 14, 2013, the Court of Appeals issued a judgment affirming the $5 verdict against us, which was fully accrued for in the first quarter of 2013 and then paid in the second quarter of 2013. We filed a petition for a rehearing of the Court of Appeals decision on March 18, 2013, which was denied by the Court of Appeals.
	The plaintiff requested royalties for post-verdict use of the machines, and requested pre-judgment interest in the amount of $.7. On July 3, 2013, the District Court ruled that the plaintiff was not entitled to additional ongoing royalties for our continued use of the machines, but did award pre-judgment interest of $.5. On August 2, 2013, both parties filed a notice of appeal of this order to the Federal Circuit Court of Appeals, but plaintiff has since withdrawn its appeal.
	In 2011, we also filed reexamination proceedings in the Patent Office (Case Nos. 95/001,543 filed February 11, 2011; 95/001,546 and 95/001,547 filed February 16, 2011), challenging the validity of each patent at issue in the lawsuit the plaintiff brought. The Patent Office examiner ruled in our favor on the key claims of one of the three patents. The Patent Office examiner initially ruled in our favor on the pertinent claims of the second of the patents, but subsequently reversed that decision. With respect to the third patent, the Patent Office examiner's decision upheld the validity of all claims. All three of these proceedings were appealed to the Board of Patent Appeals. On April 25, 2013, the plaintiff filed petitions to terminate all re-examination proceedings based on the final ruling of the Federal Circuit Court of Appeals. We opposed those petitions. The Patent Office terminated all three re-examination proceedings, two on December 16, and one on December 18, 2013. On June 4, 2014, we requested an ex parte reexamination as to one of the patents. The Patent Office did not accept our request.
	On July 29, 2013, the plaintiff filed a second lawsuit in the United States District Court for the Central District of California, Case No. CV13-05463 alleging that we and Simmons Bedding Company have continued to infringe the three patents on an automatic stapling machine and the methods used to assemble box springs, and that the plaintiff is entitled to additional damages from January 24,2012 forward. Leggett and Simmons Bedding Company filed their Answers on November 20, 2013. On September 10, 2014, the Court granted summary judgment finding that the use of an earlier version of the automatic stapling machines constituted infringement, but also finding that use of a redesigned version of the machine does not infringe any Imaginal patent. On October 17, 2014, the parties entered into a Confidential Settlement Agreement and Limited Release, whereby Leggett agreed to pay Imaginal a cash payment, which is not material to the Company, to settle the part of the case concerning the machines found to infringe. Imaginal is appealing the summary judgment ruling that the redesigned stapling machines do not infringe to the U.S. Court of Appeals for the Federal Circuit.
	At this time, we do not expect that the outcome of this matter will have a material adverse effect on our financial condition, operating cash flows or results of operations.

Interim Presentation	'
	The interim financial statements of Leggett & Platt, Incorporated (“we”, “us” or “our”) included herein have not been audited by an independent registered public accounting firm. The statements include all adjustments, including normal recurring accruals, which management considers necessary for a fair presentation of our financial position and operating results for the periods presented. We have prepared the statements pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in conformity with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. The operating results for interim periods are not necessarily indicative of results to be expected for an entire year.
	The December 31, 2013 financial position data included herein was derived from the audited consolidated financial statements included in Form 10-K, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). For further information, refer to the financial statements and footnotes included in our annual report on Form 10-K for the year ended December 31, 2013.
New Accounting Guidance	'
	In April 2014, the Financial Accounting Standards Board (FASB) issued updated guidance, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This guidance changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. We will adopt this guidance on January 1, 2015, and we do not believe it will have a material impact on our future financial statements.
	In May 2014, the FASB issued new authoritative literature, Revenue from Contracts with Customers, which supersedes much of the existing authoritative literature for revenue recognition. This guidance will be effective January 1, 2017. We are currently evaluating the newly issued guidance and the impact on our future financial statements.

	-1	Stock Option Grants
	Historically we have granted stock options in the following areas:
	•	On a discretionary basis to a broad group of employees
	•	In conjunction with our Deferred Compensation Program
	•	As compensation of outside directors
	Starting in 2013, we discontinued the broad annual option grant, and options are now offered only in conjunction with the Deferred Compensation Program discussed below, and were replaced with either cash awards or RSUs. Certain key management employees participated in a new Profitable Growth Incentive (PGI) program beginning in 2013, as discussed below.
	Deferred Compensation Program
	We offer a Deferred Compensation Program under which key managers and outside directors may elect to receive stock options, stock units or interest-bearing cash deferrals in lieu of cash compensation:
	•	Stock options under this program are granted on the last business day of the year prior to the year the compensation is earned. The number of options granted equals the deferred compensation times five, divided by the stock’s market price on the date of grant. The option has a 10-year term. It vests as the associated compensation is earned and becomes exercisable beginning 15 months after the grant date. Stock is issued when the option is exercised.
	•	Deferred stock units (DSU) under this program are acquired every two weeks (when the compensation would have otherwise been paid) at a 20% discount to the market price of our common stock on each acquisition date and they vest immediately. Expense is recorded as the compensation is earned. Stock units earn dividends at the same rate as cash dividends paid on our common stock. These dividends are used to acquire stock units at a 20% discount. Stock units are converted to common stock and distributed in accordance with the participant’s pre-set election. However, stock units may be settled in cash at the discretion of the Company. Participants must begin receiving distributions no later than ten years after the effective date of the deferral and installment distributions cannot exceed ten years.
	•	Interest-bearing cash deferrals under this program are reported in Other long-term liabilities on the balance sheet.
	(2) Stock-Based Retirement Plans
	We have two stock-based retirement plans: the tax-qualified Stock Bonus Plan (SBP) for non-highly compensated employees, and the non-qualified Executive Stock Unit Program (ESUP) for highly compensated employees. We make matching contributions to both plans. In addition to the automatic 50% match, we will make another matching contribution of up to 50% of the employee’s contributions for the year if certain profitability levels, as defined in the SBP and the ESUP, are obtained. Company contributions to the ESUP, including dividend equivalents, are used to acquire stock units at 85% of the common stock market price on the acquisition date. Participant contributions to the ESUP are credited to a diversified investment account established for the participant and we make premium contributions to the diversified investment accounts equal to 17.5% of the participant's contribution.
	(3) Performance Stock Unit Awards
	We grant Performance Stock Unit (PSU) awards in the first quarter of each year to selected officers and other key managers. These awards contain the following conditions:
	•	A service requirement—Awards generally “cliff” vest three years following the grant date; and
	•	A market condition—Awards are based on our Total Shareholder Return [TSR =Change in Stock Price + Dividends) / Beginning Stock Price] as compared to the TSR of a group of peer companies. The peer group consists of all the companies in the Industrial, Materials and Consumer Discretionary sectors of the S&P 500 and S&P Midcap 400 (approximately 320 companies). Participants will earn from 0% to 175% of the base award depending upon how our Total Shareholder Return ranks within the peer group at the end of the 3-year performance period.
	Grant date fair values are calculated using a Monte Carlo simulation of stock and volatility data for Leggett and each of the comparator companies. Grant date fair values are amortized using the straight-line method over the three-year vesting period.
	Below is a summary of the number of shares and related grant date fair value of PSU’s for the periods presented
		Nine Months Ended

		2014				2013
Total shares base award	0.2				0.2

2011		December 31, 2013		55th percentile		64.20%		.2 million		Jan-14
The above information represents the 65% portion of the award that was settled in shares of our common stock. For outstanding awards, we intend to pay 65% in shares of our common stock, although we reserve the right to pay up to 100% in cash. The additional amount that represents 35% of the award will be settled in cash, and is recorded as a liability and adjusted to fair value at each reporting period.
(4) Restricted Stock Unit Awards
RSU awards are generally granted as follows:
•	To managers in lieu of annual option grants
•	On a discretionary basis to selected managers
•	To selected executive officers in connection with employment agreements
•	As compensation for outside directors, who have a choice to receive RSUs or restricted stock
The value of these awards is determined by the stock price on the day of the award, and expense is recognized over the vesting period.
(5) Profitable Growth Incentive Awards
Starting in 2013, certain key management employees participated in a new Profitable Growth Incentive (PGI) program in lieu of the annual option grant. The PGI awards are issued as growth performance stock units (GPSUs). The GPSUs vest (0% to 250%) at the end of a two-year performance period. Vesting is based on the Company's or applicable profit center's revenue growth (adjusted by a GDP factor when applicable) and EBITDA margin at the end of a two-year performance period. The 2014 and 2013 base target PGI awards were each .1 shares. If earned, we intend to pay half in shares of our common stock and half in cash, although we reserve the right to pay up to 100% in cash. Both components are adjusted to fair value at each reporting period.
(6) Discount Stock Plan
Under the Discount Stock Plan (DSP), a tax-qualified §423 stock purchase plan, eligible employees may purchase shares of Leggett common stock at 85% of the closing market price on the last business day of each month. Shares are purchased and issued on the last business day of each month and generally cannot be sold or transferred for one year.

[1]	Stock Option Grants Historically we have granted stock options in the following areas: •On a discretionary basis to a broad group of employees•In conjunction with our Deferred Compensation Program•As compensation of outside directors Starting in 2013, we discontinued the broad annual option grant, and options are now offered only in conjunction with the Deferred Compensation Program discussed below, and were replaced with either cash awards or RSUs. Certain key management employees participated in a new Profitable Growth Incentive (PGI) program beginning in 2013, as discussed below. Deferred Compensation Program We offer a Deferred Compensation Program under which key managers and outside directors may elect to receive stock options, stock units or interest-bearing cash deferrals in lieu of cash compensation: •Stock options under this program are granted on the last business day of the year prior to the year the compensation is earned. The number of options granted equals the deferred compensation times five, divided by the stock’s market price on the date of grant. The option has a 10-year term. It vests as the associated compensation is earned and becomes exercisable beginning 15 months after the grant date. Stock is issued when the option is exercised.•Deferred stock units (DSU) under this program are acquired every two weeks (when the compensation would have otherwise been paid) at a 20% discount to the market price of our common stock on each acquisition date and they vest immediately. Expense is recorded as the compensation is earned. Stock units earn dividends at the same rate as cash dividends paid on our common stock. These dividends are used to acquire stock units at a 20% discount. Stock units are converted to common stock and distributed in accordance with the participant’s pre-set election. However, stock units may be settled in cash at the discretion of the Company. Participants must begin receiving distributions no later than ten years after the effective date of the deferral and installment distributions cannot exceed ten years.•Interest-bearing cash deferrals under this program are reported in Other long-term liabilities on the balance sheet.
[2]	Stock-Based Retirement Plans We have two stock-based retirement plans: the tax-qualified Stock Bonus Plan (SBP) for non-highly compensated employees, and the non-qualified Executive Stock Unit Program (ESUP) for highly compensated employees. We make matching contributions to both plans. In addition to the automatic 50% match, we will make another matching contribution of up to 50% of the employee’s contributions for the year if certain profitability levels, as defined in the SBP and the ESUP, are obtained. Company contributions to the ESUP, including dividend equivalents, are used to acquire stock units at 85% of the common stock market price on the acquisition date.
[3]	Discount Stock Plan Under the Discount Stock Plan (DSP), a tax-qualified §423 stock purchase plan, eligible employees may purchase shares of Leggett common stock at 85% of the closing market price on the last business day of each month. Shares are purchased and issued on the last business day of each month and generally cannot be sold or transferred for one year.
[4]	Performance Stock Unit AwardsWe grant Performance Stock Unit (PSU) awards in the first quarter of each year to selected officers and other key managers. These awards contain the following conditions:•A service requirement—Awards generally “cliff” vest three years following the grant date; and•A market condition—Awards are based on our Total Shareholder Return [TSR =Change in Stock Price + Dividends) / Beginning Stock Price] as compared to the TSR of a group of peer companies. The peer group consists of all the companies in the Industrial, Materials and Consumer Discretionary sectors of the S&P 500 and S&P Midcap 400 (approximately 320 companies). Participants will earn from 0% to 175% of the base award depending upon how our Total Shareholder Return ranks within the peer group at the end of the 3-year performance period. Grant date fair values are calculated using a Monte Carlo simulation of stock and volatility data for Leggett and each of the comparator companies. Grant date fair values are amortized using the straight-line method over the three-year vesting period. Below is a summary of the number of shares and related grant date fair value of PSU’s for the periods presented Nine Months Ended September 30, 2014 2013Total shares base award.2 .2Grant date per share fair value$30.45 $27.60Risk-free interest rate.8% .4%Expected life in years3.0 3.0Expected volatility (over expected life)25.9% 29.1%Expected dividend yield (over expected life)3.9% 4.2%Three-Year Performance CycleAward Year Completion Date TSR PerformanceRelative to the Peer Group (1%¾st) Payout as aPercent of theBase Award Number of SharesDistributed Distribution Date2010 December 31, 2012 46th percentile 91.0% .3 million January 20132011 December 31, 2013 55th percentile 64.2% .2 million January 2014The above information represents the 65% portion of the award that was settled in shares of our common stock. For outstanding awards, we intend to pay 65% in shares of our common stock, although we reserve the right to pay up to 100% in cash. The additional amount that represents 35% of the award will be settled in cash, and is recorded as a liability and adjusted to fair value at each reporting period.
[5]	Restricted Stock Unit Awards RSU awards are generally granted as follows: •To managers in lieu of annual option grants•On a discretionary basis to selected managers•To selected executive officers in connection with employment agreements•As compensation for outside directors, who have a choice to receive RSUs or restricted stockThe value of these awards is determined by the stock price on the day of the award, and expense is recognized over the vesting period.
[6]	Profitable Growth Incentive AwardsStarting in 2013, certain key management employees participated in a new Profitable Growth Incentive (PGI) program in lieu of the annual option grant. The PGI awards are issued as growth performance stock units (GPSUs). The GPSUs vest (0% to 250%) at the end of a two-year performance period. Vesting is based on the Company's or applicable profit center's revenue growth (adjusted by a GDP factor when applicable) and EBITDA margin at the end of a two-year performance period. The 2014 and 2013 base target PGI awards were each .1 shares. If earned, we intend to pay half in shares of our common stock and half in cash, although we reserve the right to pay up to 100% in cash. Both components are adjusted to fair value at each reporting period.
