Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	References in this Quarterly Report on Form 10-Q to "we," "our," "us," "LII," or the "Company" refer to Lennox International Inc. and its subsidiaries, unless the context requires otherwise. Basis of Presentation The accompanying unaudited Consolidated Balance Sheet as of June 30, 2020, the accompanying unaudited Consolidated Statements of Operations for the three and six months ended June 30, 2020 and 2019, the accompanying unaudited Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2020 and 2019, the accompanying unaudited Consolidated Statements of Stockholders' Deficit for the three and six months ended June 30, 2020 and 2019, and the accompanying unaudited Consolidated Statements of Cash Flows for the six months ended June 30, 2020 and 2019 should be read in conjunction with our audited consolidated financial statements and footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2019. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The accompanying consolidated financial statements contain all material adjustments, consisting principally of normal recurring adjustments, necessary for a fair presentation of our financial position, results of operations and cash flows. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to applicable rules and regulations, although we believe that the disclosures herein are adequate to make the information presented not misleading. The operating results for the interim periods are not necessarily indicative of the results that may be expected for a full year. Our fiscal quarterly periods are comprised of approximately 13 weeks, but the number of days per quarter may vary year-over-year. Our quarterly reporting periods usually end on the Saturday closest to the last day of March, June and September. Our fourth quarter and fiscal year ends on December 31, regardless of the day of the week on which December 31 falls. Use of Estimates The preparation of financial statements requires us to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangible assets and other long-lived assets, contingencies, guarantee obligations, indemnifications, and assumptions used in the calculation of income taxes, pension and post-retirement medical benefits, self-insurance and warranty reserves, and stock-based compensation, among others. These estimates and assumptions are based on our best estimates and judgment. We evaluate these estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. We believe these estimates and assumptions to be reasonable under the circumstances and will adjust such estimates and assumptions when facts and circumstances dictate. Volatile equity, foreign currency and commodity markets combine to increase the uncertainty inherent in such estimates and assumptions. Future events and their effects cannot be determined with precision and actual results could differ significantly from these estimates. Changes in these estimates will be reflected in the financial statements in future periods. Impact of COVID-19 Pandemic A novel strain of coronavirus (“COVID-19”) surfaced in late 2019 and has spread around the world, including to the United States. In March 2020, the World Health Organization declared COVID-19 a pandemic. The COVID-19 pandemic has disrupted our business operations and caused a significant unfavorable impact on our results of operations. In response to the COVID-19 pandemic, various national, state, and local governments where we, our suppliers, and our customers operate issued decrees prohibiting certain businesses from continuing to operate and certain classes of workers from reporting to work. Those decrees have resulted in supply chain disruption and higher employee absenteeism in our factories. Additionally, certain of our manufacturing facilities experienced short-term suspensions of operations for COVID-19 employee health concerns. The magnitude of the impact of COVID-19 remains unpredictable and we, therefore, continue to anticipate potential supply chain disruptions, employee absenteeism, short-term suspensions of manufacturing facilities and additional health and safety costs related to the COVID-19 pandemic that could unfavorably impact our business. Although these disruptions and costs are expected to be temporary, there is significant uncertainty around the duration and overall impact to our business operations. We believe it is possible that the impact of the COVID-19 pandemic could have a material adverse effect on the results of our operations, financial position and cash flows as of and for the year ended December 31, 2020. Recently Adopted Accounting Guidance In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to estimate credit losses. ASU 2016-13 is effective for SEC filers for interim and annual periods beginning after December 15, 2019. We adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost. Results for periods after January 1, 2020 are presented under ASU 2016-13 while prior period amounts continue to be reported under previously applicable accounting standards. We recorded a $1.3 million net decrease to retained earnings as of January 1, 2020 for the cumulative effect of adopting ASU 2016-13. In January 2017, the FASB issued ASU No. 2017-04, Intangible - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminates step two of the goodwill impairment test and specifies that goodwill impairment should be measured by comparing the fair value of a reporting unit with its carrying amount. Additionally, the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets should be disclosed. ASU 2017-04 is effective for annual or interim goodwill impairment tests performed in fiscal years beginning after December 15, 2019. The adoption of ASU 2017-04 did not have a material impact on our consolidated results of operations, cash flows, or statement of financial position. In August 2018, the FASB issued ASU No. 2018-15, Intangibles – Internal-Use Software (Topic 350-40): Customer’s Accounting for Implementation Costs incurred in a Cloud Computing Arrangement That is a Service Contract. ASU 2018-15 provides guidance to determine how implementation costs associated with cloud computing arrangements that are incurred to develop or obtain internal-use software should be capitalized or expensed as incurred. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019. The adoption of ASU 2018-15 did not have a material impact on our consolidated results of operations, cash flows, or statement of financial position.

Residential Heating & Cooling - We manufacture and market a broad range of furnaces, air conditioners, heat pumps, packaged heating and cooling systems, equipment and accessories to improve indoor air quality, comfort control products, replacement parts and supplies and related products for both the residential replacement and new construction markets in North America. These products are sold under various brand names and are sold either through direct sales to a network of independent installing dealers, including through our network of Lennox stores or to independent distributors. For the three months ended June 30, 2020 and 2019, direct sales represented 76% and 75% of revenues, and sales to independent distributors represented the remainder. For the six months ended June 30, 2020 and 2019, direct sales represented 75% and 74% of revenues, and sales to independent distributors represented the remainder. Given the nature of our business, customer product orders are fulfilled at a point in time and not over a period of time.

Commercial Heating & Cooling - In North America, we manufacture and sell unitary heating and cooling equipment used in light commercial applications, such as low-rise office buildings, restaurants, retail centers, churches and schools. These products are distributed primarily through commercial contractors and directly to national account customers in the planned replacement, emergency replacement and new construction markets. Revenue for the products sold is recognized at a point in time when control transfers to the customer, which is generally at time of shipment. Lennox National Account Services provides installation, service and preventive maintenance for HVAC national account customers in the United States and Canada. Revenue related to service contracts is recognized as the services are performed under the contract based on the

relative fair value of the services provided. For the three months ended June 30, 2020 and 2019, equipment sales represented 86% and 87% of revenues and the remainder of our revenue was generated from our service business. For the six months ended June 30, 2020 and 2019, equipment sales represented 85% and 85% of revenues, and the remainder of our revenue was generated from our service business.

Refrigeration - We manufacture and market equipment for the global commercial refrigeration markets under the Heatcraft Worldwide Refrigeration name. Our products are used in the food retail, food service, cold storage as well as non-food refrigeration markets. We sell these products to distributors, installing contractors, engineering design firms, original equipment manufacturers and end-users. In Europe, we also manufacture and sell unitary heating and cooling products and applied systems. Substantially all segment revenue was related to these types of equipment and systems and is recognized at a point in time when control transfers to the customer, which is generally at time of shipment. Less than 1% of segment revenue relates to services for start-up and commissioning activities.

Variable Consideration - We engage in cooperative advertising, customer rebate, and other miscellaneous programs that result in payments or credits being issued to our customers. We record these customer discounts and incentives as a reduction of sales when the sales are recorded. For certain cooperative advertising programs, we also receive an identifiable benefit (goods or services) in exchange for the consideration given, and, accordingly, record a ratable portion of the expenditure to Selling, general and administrative (“SG&A”) expenses. All other advertising, promotions and marketing costs are expensed as incurred.

Other Judgments and Assumptions - We apply the practical expedient in ASC 606-10-50-14 and do not disclose information about remaining performance obligations that have original expected durations of one year or less. Applying the practical expedient in ASC 340-40-25-4, we recognize the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that we otherwise would have recognized is one year or less. These costs are included in SG&A expenses. ASC 606-10-32-18 allows us to not adjust the amount of consideration to be received in a contract for any significant financing component if we expect to receive payment within twelve months of transfer of control of goods or services. We have elected this expedient as we expect all consideration to be received in one year or less at contract inception. We have also elected not to provide the remaining performance obligations disclosures related to service contracts in accordance with the practical expedient in ASC 606-10-55-18. We recognize revenue in the amount to which the entity has a right to invoice and have adopted this election to not provide the remaining performance obligations related to service contracts.

Contract Assets - We do not have material amounts of contract assets since revenue is recognized as control of goods is transferred or as services are performed. There are a small number of installation services that may occur over a period of time, but that period of time is generally very short in duration and right of payment does not exist until the installation is completed. Any contract assets that may arise are recorded in Other assets, net in our Consolidated Balance Sheets.

Contract Liabilities - Our contract liabilities consist of advance payments and deferred revenue. Our contract liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. We classify advance payments and deferred revenue as current or noncurrent based on the timing of when we expect to recognize revenue. Generally all contract liabilities are expected to be recognized within one year and are included in Accrued expenses in our Consolidated Balance Sheets. The noncurrent portion of deferred revenue is included in Other liabilities in our Consolidated Balance Sheets.

Net contract assets (liabilities) consisted of the following:


	June 30, 2020		December 31, 2019		$ Change		% Change

Contract liabilities - current	$	(6.8)	$	(8.4)	$	1.6	(19.0)	%
Contract liabilities - noncurrent	(5.6)		(5.9)		0.3		(5.1)	%
Total	$	(12.4)	$	(14.3)	$	1.9

For the three months ended June 30, 2020 and 2019, we recognized revenue of $2.9 million and $1.5 million and for the six months ended June 30, 2020 and 2019 we recognized revenue of $4.5 million and $2.6 million related to our contract liabilities at January 1, 2020 and 2019, respectively. Impairment losses recognized in our receivables and contract assets were de minimis in 2020 and 2019.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Derivatives:

Objectives and Strategies for Using Derivative Instruments

Commodity Price Risk - We utilize a cash flow hedging program to mitigate our exposure to volatility in the prices of metal commodities used in our production processes. Our hedging program includes the use of futures contracts to lock in prices, and as a result, we are subject to derivative losses should the metal commodity prices decrease and gains should the prices increase. We utilize a dollar cost averaging strategy so that a higher percentage of commodity price exposures are hedged near-term and lower percentages are hedged at future dates. This strategy allows for protection against near-term price volatility while allowing us to adjust to market price movements over time.

Interest Rate Risk - A portion of our debt bears interest at variable rates, and as a result, we are subject to variability in the cash paid for interest. To mitigate a portion of that risk, we may choose to engage in an interest rate swap hedging strategy to eliminate the variability of interest payment cash flows. We are not currently hedged against interest rate risk.

Foreign Currency Risk - Foreign currency exchange rate movements create a degree of risk by affecting the U.S. dollar value of assets and liabilities arising in foreign currencies. We seek to mitigate the impact of currency exchange rate movements on certain short-term transactions by periodically entering into foreign currency forward contracts.

Cash Flow Hedges

We have foreign exchange forward contracts and commodity futures contracts designated as cash flow hedges that are scheduled to mature through January 2021 and November 2021, respectively. Unrealized gains or losses from our cash flow hedges are included in Accumulated other comprehensive loss (“AOCL”) and are expected to be reclassified into earnings within the next 18 months based on the prices of the commodities and foreign currencies at the settlement dates. We recorded the following amounts in AOCL related to our cash flow hedges (in millions):


	As of June 30, 2020		As of December 31, 2019
Unrealized losses on unsettled contracts	$	1.5	$	0.2
Income tax benefit	(0.9)		(0.2)
Losses (gains) included in AOCL, net of tax ⁽¹⁾	$	0.6	$	—

(1) Assuming commodity prices and foreign currency exchange rates remain constant, we expect to reclassify $1.0 million of derivative losses into earnings within the next 12 months.

Income Taxes	, we had approximately $3.1 million in total gross unrecognized tax benefits. Of this amount $3.1 million, if recognized, would be recorded through the Consolidated Statements of Operations.We are currently under examination for our U.S. federal income taxes under the Internal Revenue Service's Compliance Assurance Program for 2019 and are subject to examination by numerous other taxing authorities in the U.S. and in foreign jurisdictions. We are generally no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by taxing authorities for years prior to 2012.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

4. Commitments and Contingencies:

Leases

We determine if an arrangement is a lease at inception. Operating leases are included in our Consolidated Balance Sheets as Right-of-use assets from operating leases, Current operating lease liabilities and Long-term operating lease liabilities. Finance leases are included in Property, plant and equipment, Current maturities of long-term debt and Long-term debt in our Consolidated Balance Sheets. We do not recognize a right-of-use asset and lease liability for leases with a term of 12 months or less. We do not separate non-lease components from lease components to which they relate and have accounted for the combined lease and non-lease components as a single lease component.

Many of our lease agreements contain renewal options; however, we do not recognize right-of-use assets or lease liabilities for renewal periods unless it is determined that we are reasonably certain of renewing the lease at inception or when a triggering event occurs. Some of our lease agreements contain rent escalation clauses (including index-based escalations), rent holidays, capital improvement funding or other lease concessions. We recognize our minimum rental expense on a straight-line basis based on the fixed components of a lease arrangement. We amortize this expense over the term of the lease beginning with the date of initial possession, which is the date we enter the leased space and begin to make improvements in preparation for its intended use. Variable lease components represent amounts that are not fixed in nature and are not tied to an index or rate, and are recognized as incurred.

Under certain of our third-party service agreements, we control a specific space or underlying asset used in providing the service by the third-party service provider. These arrangements meet the definition under ASC 842 and therefore are accounted for under ASC 842.

In determining our right-of-use assets and lease liabilities, we apply a discount rate to the minimum lease payments within each lease agreement. ASC 842 requires us to use the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. When we cannot readily determine the discount rate implicit in the lease agreement, we utilize our incremental borrowing rate. To estimate our specific incremental borrowing rates over various tenors (ranging from 1-year through 30-years), a comparable market yield curve consistent with our credit quality was calibrated to our publicly outstanding debt instruments.

We lease certain real and personal property under non-cancelable operating leases. Approximately 75% of our right-of-use assets and lease liabilities relate to our leases of real estate with the remaining amounts relating to our leases of IT equipment, fleet vehicles and manufacturing and distribution equipment.

Product Warranties and Product Related Contingencies

We provide warranties to customers for some of our products and record liabilities for the estimated future warranty-related costs based on failure rates, cost experience and other factors. We periodically review the assumptions used to determine the product warranty liabilities and will adjust the liabilities in future periods for changes in assumptions, as necessary.

Liabilities for estimated product warranty costs related to continuing operations are included in the following captions on the accompanying Consolidated Balance Sheets (in millions):


	As of June 30, 2020		As of December 31, 2019
Accrued expenses	$	37.5	$	38.2
Other liabilities	79.4		74.6
Total warranty liability	$	116.9	$	112.8

The changes in product warranty liabilities related to continuing operations for the six months ended June 30, 2020 were as follows (in millions):



Total warranty liability as of December 31, 2019	$	112.8
Warranty claims paid	(15.2)
Changes resulting from issuance of new warranties	19.5
Changes in estimates associated with pre-existing liabilities	0.1
Changes in foreign currency translation rates and other	(0.3)

Total warranty liability as of June 30, 2020	$	116.9

We have incurred, and will likely continue to incur, product costs not covered by insurance or our suppliers’ warranties, which are not included in the tables immediately above. Also, to satisfy our customers and protect our brands, we have repaired or replaced installed products experiencing quality-related issues, and will likely continue such repairs and replacements. Liabilities for such quality related issues are not material.

Litigation

We are involved in a number of claims and lawsuits incident to the operation of our businesses. Insurance coverages are maintained and estimated costs are recorded for such claims and lawsuits, including costs to settle claims and lawsuits, based on experience involving similar matters and specific facts known.

Some of these claims and lawsuits allege personal injury or health problems resulting from exposure to asbestos that was integrated into certain of our products. We have never manufactured asbestos and have not incorporated asbestos-containing components into our products for several decades. A substantial majority of these asbestos-related claims have been covered by insurance or other forms of indemnity or have been dismissed without payment. The remainder of our closed cases have been resolved for amounts that are not material, individually or in the aggregate. Our defense costs for asbestos-related claims are generally covered by insurance. However, our insurance coverage for settlements and judgments for asbestos-related claims varies depending on several factors and are subject to policy limits. We may have greater financial exposure for future settlements and judgments. The following table summarizes the expenses, net of probable insurance recoveries, for known and future asbestos-related litigation recorded in Losses (gains) and other expenses, net in the Consolidated Statements of Operations.


	For the Three Months Ended June 30,						For the Six Months Ended June 30,
	2020		2019		2020		2019
Expense (gain) for asbestos-related litigation, net	$	1.2	$	0.4	$	(0.5)	$	1.8

It is management's opinion that none of these claims or lawsuits or any threatened litigation will have a material adverse effect on our financial condition, results of operations or cash flows. Claims and lawsuits, however, involve uncertainties and it is possible that their eventual outcome could adversely affect our results of operations for a particular period.

Marshalltown Tornado and Recovery

On July 19, 2018, our manufacturing facility in Marshalltown, Iowa was severely damaged by a tornado. Insurance covered the repair or replacement of our assets that suffered damage or loss, and business interruption costs, including lost profits, and reimbursement for other expenses and costs that have been incurred relating to the damages and losses suffered. These costs and insurance recoveries are shown in Insurance proceeds for lost profits and Loss (gain) from natural disaster, net of insurance recoveries in the Consolidated Statements of Operations.

In December 2019, we reached a final settlement with our insurance carriers for a total cumulative insurance recovery of $367.5 million for the losses we incurred and will incur from the tornado. All recoveries related to the final settlement were received in 2018 and 2019.

The following table summarizes the Gain from insurance recoveries, net of losses incurred:

Short-Term Debt

Foreign Obligations

Through several of our foreign subsidiaries, we have facilities available to assist in financing seasonal borrowing needs for our foreign locations. We had no outstanding foreign obligations as of June 30, 2020 or December 31, 2019 and there were $1.9 million of borrowings and repayments on these facilities for the six months ended June 30, 2020. There were no significant borrowings or repayments on these facilities for the six months ended June 30, 2019.

Asset Securitization Program

Under the Asset Securitization Program (“ASP”), we are eligible to sell beneficial interests in a portion of our trade accounts receivable to a financial institution for cash. The ASP contains a provision whereby we retain the right to repurchase all of the outstanding beneficial interests transferred. As a result of the repurchase right, the transfer of the receivables under the ASP is not accounted for as a sale. Accordingly, the cash received from the transfer of the beneficial interests in our trade accounts receivable is reflected as secured borrowings in the accompanying Consolidated Balance Sheets and proceeds received are included in Cash flows from financing activities in the accompanying Consolidated Statements of Cash Flows. Our continued involvement with the transferred assets includes servicing, collection and administration of the transferred beneficial interests. The accounts receivable securitized under the ASP are high-quality domestic customer accounts that have not aged significantly. The receivables represented by the retained interest that we service are exposed to the risk of loss for any uncollectible amounts in the pool of receivables transferred under the ASP.

We renewed the ASP in November 2019, extending its term to November 2021 and increasing the maximum securitization amount to a range from $250.0 million to $400.0 million, depending on the period. The maximum capacity under the ASP is the lesser of the maximum securitization amount or 100% of the net pool balance less allowances, as defined by the ASP. Eligibility for securitization is limited based on the amount and quality of the qualifying accounts receivable and is calculated monthly. The eligible amounts available and beneficial interests sold were as follows (in millions):


	As of June 30, 2020		As of December 31, 2019
Eligible amount available under the ASP on qualified accounts receivable	$	306.0	$	320.0
Less: Beneficial interest transferred	(306.0)		(285.0)
Remaining amount available	$	—	$	35.0

We pay certain discount fees to use the ASP and to have the facility available to us. These fees relate to both the used and unused portions of the securitization. The used fee is based on the beneficial interest sold and calculated on either the average

LIBOR rate or floating commercial paper rate determined by the purchaser of the beneficial interest, plus a program fee of 0.70%. The average rates as of June 30, 2020 and December 31, 2019 were 1.02% and 2.51%, respectively. The unused fee is based on 101% of the maximum available amount less the beneficial interest transferred and is calculated at a rate ranging between 0.25% and 0.35%, depending on the available borrowings, throughout the term of the agreement. We recorded these fees in Interest expense, net in the accompanying Consolidated Statements of Operations.

The ASP contains certain restrictive covenants relating to the quality of our accounts receivable and cross-default provisions with our Sixth Amended and Restated Credit Facility Agreement ("Domestic Credit Facility"), senior unsecured notes and any other indebtedness we may have over $75.0 million. The administrative agent under the ASP is also a participant in our Domestic Credit Facility. The participating financial institutions have investment grade credit ratings. As of June 30, 2020, we believe we were in compliance with all covenant requirements.

Long-Term Debt

Domestic Credit Facility

On January 22, 2019, we amended our Domestic Credit Facility to provide for a $350.0 million increase in revolving commitments. The Domestic Credit Facility currently consists of a $1,000.0 million unsecured revolving credit facility and a $160.0 million unsecured term loan that matures in August 2021 (the "Maturity Date"). We will seek to extend the Maturity Date of the Domestic Credit Facility prior to its expiration.

Under our Domestic Credit Facility, we had outstanding borrowings of $702.5 million, of which $145.0 million was the term loan balance, as well as $2.4 million committed to standby letters of credit as of June 30, 2020. Subject to covenant limitations, $440.1 million was available for future borrowings. The unsecured term loan also matures on the Maturity Date and requires quarterly principal repayments of $7.5 million. The revolving credit facility includes a subfacility for swingline loans of up to $65.0 million.

Our weighted average borrowing rate on the facility was as follows:


	As of June 30, 2020		As of December 31, 2019
Weighted average borrowing rate	1.36	%	2.93	%

Our Domestic Credit Facility is guaranteed by certain of our subsidiaries and contains financial covenants relating to leverage and interest coverage. Other covenants contained in the Domestic Credit Facility restrict, among other things, certain mergers, asset dispositions, guarantees, debt, liens, and affiliate transactions. The financial covenants require us to maintain a defined Consolidated Indebtedness to Adjusted EBITDA Ratio and a Cash Flow (defined as EBITDA minus capital expenditures) to Net Interest Expense Ratio. The required ratios under our Domestic Credit Facility are detailed below:


Consolidated Indebtedness to Adjusted EBITDA Ratio no greater than			3.5 : 1.0
Cash Flow to Net Interest Expense Ratio no less than			3.0 : 1.0

Our Domestic Credit Facility contains customary events of default. These events of default include nonpayment of principal or interest, breach of covenants or other restrictions or requirements, default on certain other indebtedness or receivables securitizations (cross default), and bankruptcy. A cross default under our Domestic Credit Facility could occur if:

• We fail to pay any principal or interest when due on any other indebtedness or receivables securitization of at least $75.0 million; or

• We are in default in the performance of, or compliance with any term of any other indebtedness or receivables securitization in an aggregate principal amount of at least $75.0 million or any other condition exists which would give the holders the right to declare such indebtedness due and payable prior to its stated maturity.

Each of our major debt agreements contains provisions by which a default under one agreement causes a default in the others (a "cross default"). If a cross default under the Domestic Credit Facility, our senior unsecured notes, our lease of our corporate headquarters in Richardson, Texas (recorded as an operating lease), or our ASP were to occur, it could have a wider impact on our liquidity than might otherwise occur from a default of a single debt instrument or lease commitment.

If any event of default occurs and is continuing, lenders with a majority of the aggregate commitments may require the administrative agent to terminate our right to borrow under our Domestic Credit Facility and accelerate amounts due under our Domestic Credit Facility (except for a bankruptcy event of default, in which case such amounts will automatically become due

and payable and the lenders’ commitments will automatically terminate). As of June 30, 2020, we believe we were in compliance with all covenant requirements.

Senior Unsecured Notes

We issued $350.0 million of senior unsecured notes in November 2016 (the "Notes") which will mature on November 15, 2023 with interest being paid on May 15 and November 15 at 3.00% per annum semiannually. The Notes are guaranteed, on a senior unsecured basis, by certain of our subsidiaries that guarantee indebtedness under our Domestic Credit Facility. The indenture governing the Notes contains covenants that, among other things, limit our ability and the ability of the subsidiary guarantors to: create or incur certain liens; enter into certain sale and leaseback transactions; and enter into certain mergers, consolidations and transfers of substantially all of our assets. The indenture also contains a cross default provision which is triggered if we default on other debt of at least $75.0 million in principal which is then accelerated, and such acceleration is not rescinded within 30 days of the notice date. As of June 30, 2020, we believe we were in compliance with all covenant requirements.

Stock Repurchases	Jun. 30, 2020
Stockholders' Equity Note [Abstract]
Stock Repurchases	Our Board of Directors have authorized a total of $3 billion to repurchase shares of our common stock (collectively referred to as the "Share Repurchase Plans"), including a $500 million share repurchase authorization in December 2019. Under this program, we may repurchase shares from time to time in open market transactions and in privately negotiated transactions based on business, market, applicable legal requirements and other considerations. The repurchase program does not require the repurchase of a specific number of shares and may be terminated at any time. As of June 30, 2020, $446 million of shares may be repurchased under the Share Repurchase Plans. On February 13, 2020, we entered into a Fixed Dollar Accelerated Share Repurchase Transaction (the "ASR Agreement") with Bank of America, to effect an accelerated stock buyback of the Company's common stock. Under the ASR Agreement, we paid Bank of America $100.0 million and Bank of America delivered to us common stock representing approximately 85% of the shares expected to be purchased under the ASR Agreement. The ASR was completed in March 2020 and Bank of America delivered a total of 0.4 million shares of common stock repurchased under this ASR Agreement. We also repurchased shares for $5.6 million during the six months ended June 30, 2020 from employees who tendered their shares to satisfy minimum tax withholding obligations upon the vesting and exercise of stock-based compensation awards.

Restructuring Charges [Abstract]

Restructuring Charges

We record restructuring charges associated with management-approved restructuring plans when we reorganize or remove duplicative headcount or infrastructure within our businesses. Restructuring charges include severance costs to eliminate a specified number of employees, infrastructure charges to vacate facilities and consolidate operations, contract cancellation costs, accelerated depreciation for impaired assets and other related activities. The timing of associated cash payments is dependent upon the type of restructuring charge and can extend over a multi-year period. Restructuring charges are not included in our calculation of segment profit (loss), as more fully explained in Note 2.

Due to the economic impact of COVID-19 on our business, we implemented several cost reduction actions in the second quarter of 2020. We recorded $10.0 million of restructuring charges in the second quarter of 2020 for these actions, which consisted of employee terminations for positions that are no longer needed to support the business, selective facility closures, and cancellations of certain sales and marketing activities.

Information regarding the restructuring charges for all ongoing activities, including actions initiated in the third and fourth quarters of 2019, is presented in the following table (in millions):


	Incurred in 2020		Incurred to Date		Total Expected to be Incurred

Jun. 30, 2020

Earnings Per Share [Abstract]

Earnings Per Share

Basic earnings per share are computed by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted earnings per share are computed by dividing net income by the sum of the weighted-average number of shares and the number of equivalent shares assumed outstanding, if dilutive, under our stock-based compensation plans.

The computations of basic and diluted earnings per share for Income from continuing operations were as follows (in millions, except per share data):


	For the Three Months Ended June 30,						For the Six Months Ended June 30,
	2020		2019		2020		2019

We use segment profit or loss as the primary measure of profitability to evaluate operating performance and to allocate capital resources. We define segment profit or loss as a segment’s income or loss from continuing operations before income

taxes included in the accompanying Consolidated Statements of Operations, excluding certain items. The reconciliation in the table below details the items excluded.

Our corporate costs include those costs related to corporate functions such as legal, internal audit, treasury, human resources, tax compliance and senior executive staff. Corporate costs also include the long-term share-based incentive awards provided to employees throughout LII. We record these share-based awards as corporate costs because they are determined at the discretion of the Board of Directors and based on the historical practice of doing so for internal reporting purposes.

Any intercompany sales and associated profit (and any other intercompany items) are eliminated from segment results. There were no significant intercompany eliminations for the periods presented.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Hierarchy

The methodologies used to determine the fair value of our financial assets and liabilities at June 30, 2020 were the same as those used at December 31, 2019.

Assets and Liabilities Carried at Fair Value on a Recurring Basis

Derivatives were classified as Level 2 and primarily valued using estimated future cash flows based on observed prices from exchange-traded derivatives. We also considered the counterparty's creditworthiness, or our own creditworthiness, as appropriate. Adjustments were recorded to reflect the risk of credit default, however, they were insignificant to the overall value of the derivatives. Refer to Note 9 for more information related to our derivative instruments.

Other Fair Value Disclosures

The carrying amounts of Cash and cash equivalents, Short-term investments, Accounts and notes receivable, net, Accounts payable, and Short-term debt approximate fair value due to the short maturities of these instruments. The carrying amount of our Domestic Credit Facility in Long-term debt also approximates fair value due to its variable-rate characteristics.

The fair value of our senior unsecured notes in Long-term debt, classified as Level 2, was based on the amount of future cash flows using current market rates for debt instruments of similar maturities and credit risk. The following table presents their fair value (in millions):


	As of June 30, 2020		As of December 31, 2019
Senior unsecured notes	$	362.7	$	356.8

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Consolidated Balance Sheet as of June 30, 2020, the accompanying unaudited Consolidated Statements of Operations for the three and six months ended June 30, 2020 and 2019, the accompanying unaudited Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2020 and 2019, the accompanying unaudited Consolidated Statements of Stockholders' Deficit for the three and six months ended June 30, 2020 and 2019, and the accompanying unaudited Consolidated Statements of Cash Flows for the six months ended June 30, 2020 and 2019 should be read in conjunction with our audited consolidated financial statements and footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2019. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The accompanying consolidated financial statements contain all material adjustments, consisting principally of normal recurring adjustments, necessary for a fair presentation of our financial position, results of operations and cash flows. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to applicable rules and regulations, although we believe that the disclosures herein are adequate to make the information presented not misleading. The operating results for the interim periods are not necessarily indicative of the results that may be expected for a full year. Our fiscal quarterly periods are comprised of approximately 13 weeks, but the number of days per quarter may vary year-over-year. Our quarterly reporting periods usually end on the Saturday closest to the last day of March, June and September. Our fourth quarter and fiscal year ends on December 31, regardless of the day of the week on which December 31 falls.
Use of Estimates	Use of Estimates The preparation of financial statements requires us to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangible assets and other long-lived assets, contingencies, guarantee obligations, indemnifications, and assumptions used in the calculation of income taxes, pension and post-retirement medical benefits, self-insurance and warranty reserves, and stock-based compensation, among others. These estimates and assumptions are based on our best estimates and judgment. We evaluate these estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. We believe these estimates and assumptions to be reasonable under the circumstances and will adjust such estimates and assumptions when facts and circumstances dictate. Volatile equity, foreign currency and commodity markets combine to increase the uncertainty inherent in such estimates and assumptions. Future events and their effects cannot be determined with precision and actual results could differ significantly from these estimates. Changes in these estimates will be reflected in the financial statements in future periods.
Recent Accounting Pronouncements	In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to estimate credit losses. ASU 2016-13 is effective for SEC filers for interim and annual periods beginning after December 15, 2019. We adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost. Results for periods after January 1, 2020 are presented under ASU 2016-13 while prior period amounts continue to be reported under previously applicable accounting standards. We recorded a $1.3 million net decrease to retained earnings as of January 1, 2020 for the cumulative effect of adopting ASU 2016-13. In January 2017, the FASB issued ASU No. 2017-04, Intangible - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminates step two of the goodwill impairment test and specifies that goodwill impairment should be measured by comparing the fair value of a reporting unit with its carrying amount. Additionally, the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets should be disclosed. ASU 2017-04 is effective for annual or interim goodwill impairment tests performed in fiscal years beginning after December 15, 2019. The adoption of ASU 2017-04 did not have a material impact on our consolidated results of operations, cash flows, or statement of financial position. In August 2018, the FASB issued ASU No. 2018-15, Intangibles – Internal-Use Software (Topic 350-40): Customer’s Accounting for Implementation Costs incurred in a Cloud Computing Arrangement That is a Service Contract. ASU 2018-15 provides guidance to determine how implementation costs associated with cloud computing arrangements that are incurred to develop or obtain internal-use software should be capitalized or expensed as incurred. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019. The adoption of ASU 2018-15 did not have a material impact on our consolidated results of operations, cash flows, or statement of financial position.
Leases	Leases We determine if an arrangement is a lease at inception. Operating leases are included in our Consolidated Balance Sheets as Right-of-use assets from operating leases, Current operating lease liabilities and Long-term operating lease liabilities. Finance leases are included in Property, plant and equipment, Current maturities of long-term debt and Long-term debt in our Consolidated Balance Sheets. We do not recognize a right-of-use asset and lease liability for leases with a term of 12 months or less. We do not separate non-lease components from lease components to which they relate and have accounted for the combined lease and non-lease components as a single lease component. Many of our lease agreements contain renewal options; however, we do not recognize right-of-use assets or lease liabilities for renewal periods unless it is determined that we are reasonably certain of renewing the lease at inception or when a triggering event occurs. Some of our lease agreements contain rent escalation clauses (including index-based escalations), rent holidays, capital improvement funding or other lease concessions. We recognize our minimum rental expense on a straight-line basis based on the fixed components of a lease arrangement. We amortize this expense over the term of the lease beginning with the date of initial possession, which is the date we enter the leased space and begin to make improvements in preparation for its intended use. Variable lease components represent amounts that are not fixed in nature and are not tied to an index or rate, and are recognized as incurred. Under certain of our third-party service agreements, we control a specific space or underlying asset used in providing the service by the third-party service provider. These arrangements meet the definition under ASC 842 and therefore are accounted for under ASC 842. In determining our right-of-use assets and lease liabilities, we apply a discount rate to the minimum lease payments within each lease agreement. ASC 842 requires us to use the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. When we cannot readily determine the discount rate implicit in the lease agreement, we utilize our incremental borrowing rate. To estimate our specific incremental borrowing rates over various tenors (ranging from 1-year through 30-years), a comparable market yield curve consistent with our credit quality was calibrated to our publicly outstanding debt instruments. We lease certain real and personal property under non-cancelable operating leases. Approximately 75% of our right-of-use assets and lease liabilities relate to our leases of real estate with the remaining amounts relating to our leases of IT equipment, fleet vehicles and manufacturing and distribution equipment.
