NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. 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 September 30, 2020, the accompanying unaudited Consolidated Statements of Operations for the three and nine months ended September 30, 2020 and 2019, the accompanying unaudited Consolidated Statements of Comprehensive Income for the three and nine months ended September 30, 2020 and 2019, the accompanying unaudited Consolidated Statements of Stockholders' Deficit for the three and nine months ended September 30, 2020 and 2019, and the accompanying unaudited Consolidated Statements of Cash Flows for the nine months ended September 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. For convenience, the 13-week periods comprising each fiscal quarter are denoted by the last day of the respective calendar quarter.

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.

7

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.

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.

2. Reportable Business Segments:

We operate in three reportable business segments of the heating, ventilation, air conditioning and refrigeration (“HVACR”) industry. Our segments are organized primarily by the nature of the products and services we provide. The following table describes each segment:

Segment	Product or Services	Markets Served	Geographic Areas
Residential Heating & Cooling	Furnaces, air conditioners, heat pumps, packaged heating and cooling systems, indoor air quality equipment, comfort control products, replacement parts and supplies	Residential Replacement; Residential New Construction	United States Canada
Commercial Heating & Cooling	Unitary heating and air conditioning equipment, applied systems, controls, installation and service of commercial heating and cooling equipment, and variable refrigerant flow commercial products	Light Commercial	United States Canada
Refrigeration	Condensing units, unit coolers, fluid coolers, air cooled condensers, air handlers, process chillers, controls, and compressorized racks	Light Commercial; Food Preservation; Non-Food/Industrial	United States Canada Europe

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

8

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.

Segment Data

Net sales and segment profit (loss) for each segment, along with a reconciliation of segment profit (loss) to Operating income, are shown below (in millions):

3. 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 September 30,				For the Nine Months Ended September 30,
	2020		2019		2020		2019
Net income	$	131.7	$	114.7	$	244.6	$	294.7

The following stock appreciation rights and restricted stock units were outstanding but not included in the diluted earnings per share calculation because the assumed exercise of such rights would have been anti-dilutive (in millions, except for per share data):

	For the Three Months Ended September 30,			For the Nine Months Ended September 30,
	2020	2019		2020	2019
Weighted-average number of shares	0.1	—		0.1	—
Price per share	$257.08	$	—	$257.08	$	—

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.

10

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 72% 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 September 30, 2020		As of December 31, 2019
Accrued expenses	$	37.0	$	38.2
Other liabilities	80.4		74.6
Total warranty liability	$	117.4	$	112.8

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

Total warranty liability as of December 31, 2019	$	112.8
Warranty claims paid	(26.9)
Changes resulting from issuance of new warranties	31.2
Changes in estimates associated with pre-existing liabilities	0.3
Changes in foreign currency translation rates and other	—
Total warranty liability as of September 30, 2020	$	117.4

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.

11

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 (in millions):

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2020		2019		2020		2019
Expense (gain) for asbestos-related litigation, net	$	2.4	$	1.5	$	1.9	$	3.3

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.

Natural Disasters and Recovery

On July 19, 2018, our manufacturing facility in Marshalltown, Iowa was severely damaged by a tornado. On August 10, 2020, the Marshalltown facility was partially damaged by a derecho wind storm. The costs and losses incurred as well as any insurance recoveries for both of these natural disasters are shown in Loss (gain) from natural disasters, net of insurance recoveries in the Consolidated Statements of Operations.

The following table summarizes the components of Loss (gain) from natural disasters, net of insurance recoveries (in millions):

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2020		2019		2020		2019

Loss (gain) from natural disasters, net of insurance recoveries	$	4.9	$	(7.1)	$	7.6	$	(85.4)

Marshalltown 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. 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 Loss (gain) from natural disasters, net of insurance recoveries relating to the tornado (in millions):

Marshalltown Wind Storm

We have insurance for the repair and replacement of our assets that suffered damage or loss, and are working closely with our insurance carriers and claims adjusters to ascertain the amount of insurance recoveries due to us as a result of the damage and losses we suffered. Our insurance policies also provide business interruption coverage, including lost profits and reimbursement for other expenses and costs that have been incurred related to the damages and losses suffered. The following table summarizes the Loss (gain) from natural disasters, net of insurance recoveries relating to the wind storm (in millions):

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,

5. 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 September 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.

13

We also repurchased shares for $10.1 million during the nine months ended September 30, 2020 from employees who tendered their shares to satisfy minimum tax withholding obligations upon the vesting and exercise of stock-based compensation awards.

6. Divestitures:

During the first quarter of 2019, we obtained Board of Directors' approval and signed an agreement with EPTA S.p.A., a private Italian company, for the sale of our Kysor Warren business. The sale was completed on March 29, 2019 and the following table summarizes the net loss recognized in connection with this divestiture. There were no gains or losses on the sale of this business for the nine months ended September 30, 2020.

(Amounts in millions)	For the Year Ended December 31, 2019
Cash received from the buyer	$	49.0
Net assets sold	(52.0)
AOCI reclassification adjustments, primarily foreign currency translation	(2.1)
Direct costs to sell	(5.5)
Loss on sale of business	$	(10.6)

7. 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 for the nine months ended September 30, 2020 for these actions, which consisted of employee terminations for positions that were no longer needed to support the business, selective facility closures, and cancellations of certain sales and marketing activities. We also recorded $0.6 million of restructuring charges for restructuring plans initiated in the third and fourth quarters of 2019.

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

	Incurred in 2020		Incurred to Date		Total Expected to be Incurred
Severance and related expense	$	4.5	$	5.8	$	6.5
Asset write-offs and accelerated depreciation	1.9		3.6		3.6
Lease termination	(0.1)		1.0		1.0
Other	4.3		4.8		5.5
Total restructuring charges	$	10.6	$	15.2	$	16.6

While restructuring charges are excluded from our calculation of segment profit (loss), the table below presents the restructuring charges associated with each segment (in millions):

	Incurred in 2020		Incurred to Date		Total Expected to be Incurred
Residential Heating & Cooling	$	6.5	$	9.4	$	9.4

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 September 30, 2020 and 2019, direct sales represented 74% and 74% of revenues, and sales to independent distributors represented the remainder. For the nine months ended September 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

15

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 September 30, 2020 and 2019, equipment sales represented 83% and 86% of revenues and the remainder of our revenue was generated from our service business. For the nine months ended September 30, 2020 and 2019, equipment sales represented 84% and 86% 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:

	September 30, 2020		December 31, 2019		$ Change		% Change
Contract liabilities - current	$	(7.0)	$	(8.4)	$	1.4	(16.7)	%

For the three months ended September 30, 2020 and 2019, we recognized revenue of $1.4 million and $0.2 million and for the nine months ended September 30, 2020 and 2019 we recognized revenue of $5.9 million and $2.8 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.

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 February 2022, 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

17

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 September 30, 2020		As of December 31, 2019
Unrealized (gains) losses on unsettled contracts	$	(2.0)	$	0.2
Income tax expense (benefit)	0.3		(0.2)
(Gains) included in AOCL, net of tax (1)	$	(1.7)	$	—

⁽¹⁾ Assuming commodity prices and foreign currency exchange rates remain constant, we expect to reclassify $1.2 million of derivative gains into earnings within the next 12 months.

Stock-Based Compensation:

We issue various long-term incentive awards, including performance share units, restricted stock units and stock appreciation rights under the Lennox International Inc. 2019 Incentive Plan, as amended and restated. Stock-based compensation expense related to continuing operations is included in Selling, general and administrative expenses in the accompanying Consolidated Statements of Operations as follows (in millions):

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2020		2019		2020		2019

11. Income Taxes:

As of September 30, 2020, we had approximately $3.2 million in total gross unrecognized tax benefits. Of this amount $3.2 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.

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 September 30, 2020 or December 31, 2019 and there were $4.6 million of borrowings and repayments on these facilities for the nine months ended September 30, 2020. There were $5.3 million of borrowings and repayments on these facilities for the nine months ended September 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 September 30, 2020		As of December 31, 2019
Eligible amount available under the ASP on qualified accounts receivable	$	328.9	$	320.0
Less: Beneficial interest transferred	—		(285.0)
Remaining amount available	$	328.9	$	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

19

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 September 30, 2020 and December 31, 2019 were 0.88% 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 Seventh 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 September 30, 2020, we believe we were in compliance with all covenant requirements.

Long-Term Debt

Domestic Credit Facility

On July 30, 2020, we amended our Domestic Credit Facility to extend the term of our revolving credit facility by one year and to provide for a $250.0 million decrease in revolving commitments. The amended Domestic Credit Facility currently consists of a $750.0 million unsecured revolving credit facility that matures in August 2022. The previously outstanding unsecured term loan was fully repaid in September 2020.

Under our Domestic Credit Facility, we had outstanding borrowings of $34.5 million as well as $2.2 million committed to standby letters of credit as of September 30, 2020. Subject to covenant limitations, $713.3 million was available for future borrowings. 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 September 30, 2020		As of December 31, 2019
Weighted average borrowing rate	1.65	%	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 September 30, 2020, we believe we were in compliance with all covenant requirements.

20

Senior Unsecured Notes

We issued two series of senior unsecured notes on July 30, 2020 for $300.0 million each, which will mature on August 1, 2025 (the "2025 Notes") and August 1, 2027 (the "2027 Notes") with interest being paid semi-annually on February and August at 1.35% and 1.70% respectively, per annum. We also issued $350.0 million of senior unsecured notes in November 2016 (the "2023 Notes," and together with the 2025 Notes and the 2027 Notes, the "Notes") which will mature on November 15, 2023 with interest being paid semi-annually on May 15 and November 15 at 3.00% per annum.

All 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 September 30, 2020, we believe we were in compliance with all covenant requirements.

14. Fair Value Measurements:

Fair Value Hierarchy

The methodologies used to determine the fair value of our financial assets and liabilities at September 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 September 30, 2020		As of December 31, 2019
Senior unsecured notes	$	945.0	$	356.8

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, that are based on information currently available to management as well as management’s assumptions and beliefs as of the date such statements were made. All statements, other than statements of historical fact, included in this Quarterly Report on Form 10-Q constitute forward-looking statements, including but not limited to statements identified by forward-looking terminology, such as the words “may,” “will,” “should,” “plan,” “anticipate,” “believe,” “intend,” “estimate” and “expect” and similar expressions. Such statements reflect our current views with respect to future events, based on what we believe are reasonable assumptions; however, such statements are subject to certain risks and uncertainties.

In addition to the specific uncertainties discussed elsewhere in this Quarterly Report on Form 10-Q, the risk factors set forth in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019, and those set forth in Part II, “Item 1A. Risk Factors” of this report, if any, may affect our performance and results of operations. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may differ materially from those in the forward-looking statements. We disclaim any intention or obligation to update or review any forward-looking statements or information, whether as a result of new information, future events or otherwise, except as required by law.

Business Overview

We operate in three reportable business segments of the heating, ventilation, air conditioning and refrigeration (“HVACR”) industry. Our reportable segments are Residential Heating & Cooling, Commercial Heating & Cooling, and Refrigeration. For additional information regarding our reportable segments, see Note 2 in the Notes to the Consolidated Financial Statements.

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. For convenience, throughout this Management’s Discussion and Analysis of Financial Condition and Results of Operations, the 13-week periods comprising each fiscal quarter are denoted by the last day of the respective calendar quarter.

We sell our products and services through a combination of direct sales, distributors and company-owned parts and supplies stores. The demand for our products and services is seasonal and significantly impacted by the weather. Warmer than normal summer temperatures generate demand for replacement air conditioning and refrigeration products and services, and colder than normal winter temperatures have a similar effect on heating products and services. Conversely, cooler than normal summers and warmer than normal winters depress the demand for HVACR products and services. In addition to weather, demand for our products and services is influenced by national and regional economic and demographic factors, such as interest rates, the availability of financing, regional population and employment trends, new construction, general economic conditions, and consumer spending habits and confidence. A substantial portion of the sales in each of our business segments is attributable to replacement business, with the balance comprised of new construction business.

The principal elements of cost of goods sold are components, raw materials, factory overhead, labor, estimated warranty costs, and freight and distribution costs. The principal raw materials used in our manufacturing processes are steel, copper and aluminum. In recent years, pricing volatility for these commodities and related components, including the impact of imposed tariffs on the import of certain of our raw materials and components, has impacted us and the HVACR industry in general. We seek to mitigate the impact of volatility in commodity prices through a combination of price increases, commodity contracts, improved production efficiency and cost reduction initiatives. We also partially mitigate volatility in the prices of these commodities by entering into futures contracts and fixed forward contracts.

Impact of COVID-19 Pandemic and the Resulting Changes to our 2020 Financial Performance

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.

23

Additionally, certain of our manufacturing facilities experienced short-term suspensions of operations for COVID-19 employee health concerns during the second and third quarters of 2020.

Due to the adverse impact of the COVID-19 pandemic on our European manufacturing facilities and the resulting downturn in the related business, we recorded an $8 million valuation allowance in the first quarter of 2020 on certain foreign deferred tax assets as we concluded that it was no longer more likely than not that these foreign tax loss carryforwards would be realized.

In April 2020, we implemented cost reduction actions to realize $115 million of SG&A savings relative to our initial 2020 financial plans based on expectations that the North American unitary HVAC and refrigeration market would be negatively impacted by approximately 20% due to the pandemic. During the third quarter, we revised our outlook for the remainder of 2020 due to the improved performance of our end markets and our strong operational performance. We are now planning for $65 million of SG&A savings this year, with the decrease in savings due primarily to reinstituting the temporary salary reductions, increasing sales commissions and paying performance-based incentive compensation.

In connection with these cost saving actions, we incurred pre-tax charges of $10 million in the second and third quarters of 2020 related primarily to personnel severance and benefits and facility exit costs. Also, we incurred $6 million of expenses for the nine months ended September 30, 2020 for facility cleaning and sanitization supplies to ensure the health and safety of our employees.

The magnitude of the impact of COVID-19 remains unpredictable and we, therefore, continue to anticipate potential supply chain disruptions, employee absenteeism and short-term suspensions of manufacturing facilities, and additional health and safety costs related to the COVID-19 pandemic that could unfavorably impact our business. Since the first quarter of 2020, we have reset our financial expectations and, based on our latest guidance, now expect 2020 revenue to be down 5% to 9% from last year versus our initial 2020 guidance for growth of 4% to 8%. Additionally, we now expect Diluted EPS from continuing operations in the range of $8.35 to $8.95 for the year as compared to our initial expected range of $11.30 to $11.90 for 2020.

We expect our cash generation to remain strong for 2020 as our working capital requirements decline, and currently project approximately $525 million in cash flows from operations for the year. We reduced our capital expenditure plans for 2020 from $153 million initially to $100 million. We are rated investment grade by both S&P and Moody’s, and we expect to remain well within our debt covenants. We do not anticipate any liquidity concerns as we issued $600 million in senior unsecured notes in the third quarter of 2020 and extended the term of bank revolver by one year until the latter half of 2022. Our quarterly dividend plans are unchanged, most recently $0.77 per share, or more than $115 million in total payments for the year. We repurchased $100 million of stock in the first quarter of the $400 million we had planned to repurchase for the year. However, we placed the remaining repurchase plans for 2020 on hold.

Financial Overview

Results for the third quarter of 2020 were mixed and adversely impacted by the business downturn caused by the COVID-19 pandemic. Year over year sales and profit were up in our Residential Heating & Cooling segment primarily due to higher volumes, while they were down in our Commercial Heating & Cooling and Refrigeration segments primarily due to lower sales volumes. The Residential Heating & Cooling segment saw a 13% increase in net sales and a $27 million increase in segment profit. The Commercial Heating & Cooling segment had a 18% decrease in net sales and a $8 million decrease in segment profit. The Refrigeration segment had a 12% decline in net sales and a $7 million decline in segment profit.

Financial Highlights

•Net sales increased $22 million to $1,055 million in the third quarter of 2020 driven by favorable price and mix combined and net volume increases.

•Operating income in the third quarter of 2020 increased $10 million to $167 million primarily driven by factory productivity, lower commodity costs, and sourcing and engineering-led cost reductions, partially offset by non-recurring insurance recoveries in 2019 for lost profits related to the Marshalltown tornado.

•Net income for the third quarter of 2020 increased $17 million to $132 million.

•Diluted earnings per share from continuing operations were $3.42 per share in the third quarter of 2020 compared to $2.94 per share in the third quarter of 2019.

•For the nine months ended September 30, 2020, we returned $89 million to shareholders through dividend payments and repurchased $100 million of common stock through our share repurchase program.

Net Sales

Net sales increased 2% in the third quarter of 2020 compared to the third quarter of 2019 driven by higher sales volumes of 1% and favorable combined price and mix of 1%.

Gross Profit

Gross profit margin in the third quarter of 2020 increased 170 basis points ("bps") to 30.6% compared to 28.9% in the third quarter of 2019. We saw margin increases of 80 bps from lower commodity costs, 80 bps from sourcing and engineering-led cost reductions, 60 bps from lower freight and distribution costs, and 50 bps from factory productivity. Partially offsetting these were margin decreases of 70 bps from unfavorable combined price and mix and 30 bps from higher tariffs.

Selling, General and Administrative Expenses

Selling, general and administrative expenses ("SG&A") increased $8 million to $152 million in the third quarter of 2020 compared to $143 million in the third quarter of 2019 primarily due to higher incentive compensation costs. As a percentage of net sales, SG&A increased 50 bps to 14.4% .

Charges incurred related to COVID-19 pandemic	3.0		—
Other items, net	(0.1)		0.6
Losses (gains) and other expenses, net (pre-tax)	$	3.4	$	2.2

The net change in unrealized losses on unsettled futures contracts was due to changes in commodity prices relative to the unsettled futures contract prices. For more information on our futures contracts, see Note 9 in the Notes to the Consolidated Financial Statements. For more information on special legal contingency charges and asbestos-related litigation, see Note 4 in the Notes to the Consolidated Financial Statements. The environmental liabilities related to estimated remediation costs for contamination at some of our facilities. The charges incurred related to the COVID-19 pandemic related primarily to facility cleaning costs and sanitization supplies to ensure the health and safety of our employees.

Restructuring Charges

Restructuring charges were insignificant in the third quarter of 2020 and related to ongoing cost reduction actions taken in prior periods. For additional information on our restructuring activities, refer to Note 7 in the Notes to the Consolidated Financial Statements.

Gains and Losses related to Natural Disasters

On July 19, 2018, our manufacturing facility in Marshalltown, Iowa was severely damaged by a tornado. On August 10, 2020, the Marshalltown facility was partially damaged by a derecho wind storm. The costs and losses incurred as well as any insurance recoveries for both of these natural disasters are shown in Loss (gain) from natural disasters, 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. During the third quarter of 2020, we incurred expenses of less than $1 million related to damages caused by the tornado, which primarily related to other restoration costs.

We have insurance for the repair and replacement of our assets that suffered damage or loss related to the wind storm. We are working closely with our insurance carriers and claims adjusters to ascertain the amount of insurance recoveries due to us as a result of the damage and losses we suffered. Our insurance policies also provide business interruption coverage, including lost profits and reimbursement for other expenses and costs that have been incurred related to the damages and losses suffered. During the third quarter of 2020, we incurred expenses of approximately $5 million related to damages caused by the wind storm, which included site clean up, building repairs and other restoration costs.

See Note 4 in the Notes to the Consolidated Financial Statements for additional information.

Income from Equity Method Investments

We participate in two joint ventures that are engaged in the manufacture and sale of compressors, unit coolers and condensing units. We exert significant influence over these affiliates based upon our ownership, but do not control them due to

26

venture partner participation. Accordingly, these joint ventures have been accounted for under the equity method and their financial position and results of operations are not consolidated. Income from equity method investments of $4 million in the third quarter of 2020 was up slightly compared to the third quarter of 2019.

Interest Expense, net

Interest expense, net of $7 million in the third quarter of 2020 was down $6 million from $13 million in the third quarter of 2019 due to lower borrowing costs and fewer borrowings.

Income Taxes

Our effective tax rate was 17.3% for the third quarter of 2020 compared to 20.2% for the third quarter of 2019. The rate decreased primarily due to higher excess tax benefits from stock-based compensation and a favorable mix of income from jurisdictions with lower tax rates. We expect our annual effective tax rate in 2020 to be between 19% and 20%, after excluding the impacts of excess tax benefits recorded under ASU No. 2016-09, after the $8 million valuation allowance recorded in the first quarter of 2020 and after the tax impacts of restructuring and pandemic-related charges.

Segment profit decreased $7 million in the third quarter of 2020 compared to the third quarter of 2019 due to $9 million from lower sales volumes, $2 million of factory inefficiencies, and $1 million of lower income from equity method investments. Partially offsetting these declines was $3 million from lower SG&A expenses, $1 million from lower commodity costs, and $1 million from favorable foreign currency exchange rates.

Corporate and Other

Corporate and other expenses increased $10 million in the third quarter of 2020 compared to the third quarter of 2019 primarily due to higher incentive compensation costs.

Net Sales

Net sales decreased 7% in the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 due to lower sales volumes of 7% and a 1% decline related to the sale of our Kysor Warren business in the first quarter of 2019, partially offset by 1% from favorable combined price and mix.

Gross Profit

Gross profit margins for the nine months ended September 30, 2020 decreased 40 bps to 28.1% compared to the nine months ended September 30, 2019. Our profit margin decreased 150 bps from unfavorable combined price and mix, 60 bps from factory inefficiencies, 40 bps from higher product warranties and other product costs, and 10 bps from higher tariffs for certain Chinese imports. These were partially offset by 80 bps from lower commodities costs, 70 bps from sourcing and engineering-led cost reductions, 50 bps from lower freight and distribution costs, and 20 bps from the divested Kysor Warren business which had lower margins.

Selling, General and Administrative Expenses

SG&A declined $29 million to $413 million for the nine months ended September 30, 2020 compared to $442 million for the nine months ended September 30, 2019 primarily due to lower salaries and discretionary expenditures, and the sale of our Kysor Warren business in the first quarter of 2019. As a percentage of net sales, SG&A increased 10 bps to 15.2% from 15.1%.

For more information on our futures contracts, see Note 9 in the Notes to the Consolidated Financial Statements. For more information on special legal contingency charges and asbestos-related litigation, see Note 4 in the Notes to the Consolidated Financial Statements. The environmental liabilities related to estimated remediation costs for contamination at some of our facilities. The charges incurred related to the COVID-19 pandemic related primarily to facility cleaning costs and sanitization supplies to ensure the health and safety of our employees.

Restructuring Charges

Restructuring charges were $11 million for the nine months ended September 30, 2020 and related to several cost reduction actions taken in response to the economic impact of the COVID-19 pandemic on our business. These actions consisted of employee terminations for positions that were no longer needed to support the business, selective facility closures, and cancellations of certain sales and marketing activities. For additional information on our restructuring activities, refer to Note 7 in the Notes to the Consolidated Financial Statements.

29

Loss on Sale of Business

We recognized a loss of $9 million for the nine months ended September 30, 2019 related to the sale of our Kysor Warren business in the first quarter of 2019. There were no losses related to this sale for the nine months ended September 30, 2020. Refer to Note 6 in the Notes to the Consolidated Financial Statements for additional information on this divestiture.

Gains and Losses related to Natural Disasters

On July 19, 2018, our manufacturing facility in Marshalltown, Iowa was severely damaged by a tornado. On August 10, 2020, the Marshalltown facility was partially damaged by a derecho wind storm. The costs and losses incurred as well as any insurance recoveries for both of these natural disasters are shown in Loss (gain) from natural disasters, 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. For the nine months ended September 30, 2020, we incurred expenses of $3 million related to damages caused by the tornado, which primarily related to other restoration costs.

We have insurance for the repair and replacement of our assets that suffered damage or loss related to the wind storm. We are working closely with our insurance carriers and claims adjusters to ascertain the amount of insurance recoveries due to us as a result of the damage and losses we suffered. Our insurance policies also provide business interruption coverage, including lost profits and reimbursement for other expenses and costs that have been incurred related to the damages and losses suffered. During the third quarter of 2020, we incurred expenses of approximately $5 million related to damages caused by the wind storm, which included site clean up, building repairs and other restoration costs.

Income from Equity Method Investments

Income from equity method investments of $11 million for the nine months ended September 30, 2020 was up approximately $1 million compared to the nine months ended September 30, 2019.

Pension Settlements

In the second quarter of 2019, we entered into an agreement with Pacific Life Insurance Company to purchase a group annuity contract and transfer $100.0 million of our pension plan assets and $105.6 million of related pension benefit obligations. We recognized a $60.6 million pension settlement charge in the Statement of Operations as a result of this transaction. There were less than $1 million of pension settlements for the nine months ended September 30, 2020. For additional information, refer to Note 10 in the Notes to the Consolidated Financial Statements.

Interest Expense, net

Interest expense, net of $22 million for the nine months ended September 30, 2020 decreased $15 million from $37 million for the nine months ended September 30, 2019 due to lower borrowing costs and lower borrowings.

Income Taxes

Our effective tax rate increased to 21.9% for the nine months ended September 30, 2020 compared to 19.5% for the nine months ended September 30, 2019 primarily due to lower excess tax benefits from stock-based compensation and the recording of a $8 million valuation allowance on certain foreign deferred tax assets recorded in the first quarter of 2020.

Corporate and Other

Corporate and other expenses increased $7 million in the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 due to higher incentive compensation costs.

Liquidity and Capital Resources

Our working capital and capital expenditure requirements are generally met through internally generated funds, bank lines of credit and an asset securitization arrangement. Working capital needs are generally greater in the first and second quarters due to the seasonal nature of our business cycle.

Statement of Cash Flows

The following table summarizes our cash flow activity for the nine months ended September 30, 2020 and 2019 (in millions):

	For the Nine Months Ended September 30,
	2020		2019
Net cash provided by operating activities	$	446.2	$	124.5
Net cash used in investing activities	(56.5)		(23.1)
Net cash used in financing activities	(365.0)		(102.8)

Net Cash Provided by Operating Activities - We generated $446 million in cash from operating activities during the nine months ended September 30, 2020. The increase in net cash provided by operating activities for the nine months ended September 30, 2020 compared to the same period in 2019 reflects lower working capital requirements in 2020.

Net Cash Used in Investing Activities - Capital expenditures were $56 million in the nine months ended September 30, 2020 compared to $77 million in the same period of 2019. Capital expenditures in 2020 were primarily related to the expansion of manufacturing capacity and equipment, and investments in systems and software to support the overall enterprise. For the nine months ended September 30, 2019, we also received net proceeds of $44 million for the sale of our Kysor Warren business and insurance recoveries of $12 million to replace property and equipment damaged by the Marshalltown tornado.

Net Cash Used in Financing Activities - Net cash used in financing activities in the nine months ended September 30, 2020 increased to $365 million from $103 million in the same period of 2019. The increase was primarily due to lower net borrowings, which resulted from reduced working capital requirements, and was partially offset by fewer stock repurchases. We repurchased $100 million of shares for the nine months ended September 30, 2020 and returned $89 million to shareholders through dividend payments. For additional information on share repurchases, refer to Note 5 in the Notes to the Consolidated Financial Statements.

Debt Position

The following table details our lines of credit and financing arrangements as of September 30, 2020 (in millions):

32

	Outstanding Borrowings
Current maturities of long-term debt:
Asset securitization program (2)	$	—
Finance lease obligations	9.6
Domestic credit facility (1)	—
Debt issuance costs	(2.6)
Total current maturities of long-term debt	$	7.0
Long-term debt:
Finance lease obligations	28.8
Domestic credit facility (1)	34.5
Senior unsecured notes	950.0
Debt issuance costs	(6.7)
Total long-term debt	1,006.6
Total debt	$	1,013.6

⁽¹⁾ The available future borrowings on our domestic credit facility are $713.3 million, after being reduced by the outstanding borrowings and $2.2 million in outstanding standby letters of credit. We also had $29.6 million in outstanding standby letters of credit outside of the domestic credit facility as of September 30, 2020. The domestic credit facility matures in August 2022.

⁽²⁾ The maximum securitization amount ranges from $250.0 million to $400.0 million, depending on the period. The maximum capacity of the ASP is the lesser of the maximum securitization amount or 100% of the net pool balance less reserves, as defined under the ASP. Refer to Note 12 in the Notes to the Consolidated Financial Statements for more information.

Financial Leverage

We periodically review our capital structure to ensure the appropriate levels of leverage and liquidity. We may access the capital markets, as necessary, based on business needs and to take advantage of favorable interest rate environments or other market conditions. We also evaluate our debt-to-capital and debt-to-EBITDA ratios to determine, among other considerations, the appropriate targets for capital expenditures and share repurchases under our share repurchase programs. Our debt-to-total-capital ratio decreased to 112.9% at September 30, 2020 from 117.0% at December 31, 2019.

As of September 30, 2020, our senior credit ratings were Baa3 with a stable outlook, and BBB with a stable outlook, by Moody's Investors Service, Inc. ("Moody's") and Standard & Poor's Rating Group ("S&P"), respectively. The security ratings are not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency. Each rating should be evaluated independently of any other rating. Our goal is to maintain investment grade ratings from Moody's and S&P to help ensure the capital markets remain available to us.

Liquidity

We believe our cash and cash equivalents of $55 million, future cash generated from operations and available future borrowings are sufficient to fund operations, planned capital expenditures, future contractual obligations, potential share repurchases and dividends and other needs in the foreseeable future. Included in our cash and cash equivalents of $55 million as of September 30, 2020 was $25 million of cash held in foreign locations. Our cash held in foreign locations is used for investing and operating activities in those locations, and we generally do not have the need or intent to repatriate those funds to the United States. An actual repatriation in the future from our non-U.S. subsidiaries could be subject to foreign withholding taxes and U.S. state taxes.

Guarantees related to our Debt Obligations

Our senior unsecured notes were issued by Lennox International Inc. (the "Parent") and are unconditionally guaranteed by certain of our subsidiaries (the "Guarantor Subsidiaries") and are not secured by our other subsidiaries. The Guarantor Subsidiaries are 100% owned and consolidated, all guarantees are full and unconditional, and all guarantees are joint and several.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

For quantitative and qualitative disclosures about market risk affecting LII, see "Quantitative and Qualitative Disclosures About Market Risk" in Item 7A of Part II of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

As required by Rule 13a-15 under the Exchange Act, we carried out an evaluation, under the supervision and with the participation of our current management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of September 30, 2020, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the applicable rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II - Other Information

Item 1. Legal Proceedings

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. It is management's opinion that none of these claims or lawsuits will have a material adverse effect, individually or in the aggregate, on our financial position, results of operations or cash flows.

Item 1A. Risk Factors

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019, which could materially affect our business, financial condition or results of operations. There have been no material changes to our risk factors from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019 and in Form 10-Q for the quarter ended June 30, 2020.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

In the third quarter of 2020, we purchased shares of our common stock as follows:

	Total Number of Shares Purchased (1)	Average Price Paid per Share (including fees)		Total Number of Shares Purchased As Part of Publicly Announced Plans	Approximate Dollar Value of Shares that may yet be Purchased under our Share Repurchase Plans (in millions)

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 September 30, 2020, the accompanying unaudited Consolidated Statements of Operations for the three and nine months ended September 30, 2020 and 2019, the accompanying unaudited Consolidated Statements of Comprehensive Income for the three and nine months ended September 30, 2020 and 2019, the accompanying unaudited Consolidated Statements of Stockholders' Deficit for the three and nine months ended September 30, 2020 and 2019, and the accompanying unaudited Consolidated Statements of Cash Flows for the nine months ended September 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. For convenience, the 13-week periods comprising each fiscal quarter are denoted by the last day of the respective calendar quarter.

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.

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 September 30, 2020 and 2019, direct sales represented 74% and 74% of revenues, and sales to independent distributors represented the remainder. For the nine months ended September 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 September 30, 2020 and 2019, equipment sales represented 83% and 86% of revenues and the remainder of our revenue was generated from our service business. For the nine months ended September 30, 2020 and 2019, equipment sales represented 84% and 86% 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:

	September 30, 2020		December 31, 2019		$ Change		% Change
Contract liabilities - current	$	(7.0)	$	(8.4)	$	1.4	(16.7)	%
Contract liabilities - noncurrent	(5.6)		(5.9)		0.3		(5.1)	%
Total	$	(12.6)	$	(14.3)	$	1.7

For the three months ended September 30, 2020 and 2019, we recognized revenue of $1.4 million and $0.2 million and for the nine months ended September 30, 2020 and 2019 we recognized revenue of $5.9 million and $2.8 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 February 2022, 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 September 30, 2020		As of December 31, 2019
Unrealized (gains) losses on unsettled contracts	$	(2.0)	$	0.2
Income tax expense (benefit)	0.3		(0.2)
(Gains) included in AOCL, net of tax (1)	$	(1.7)	$	—

(1) Assuming commodity prices and foreign currency exchange rates remain constant, we expect to reclassify $1.2 million of derivative gains into earnings within the next 12 months.

	Sep. 30, 2020
Income Tax Disclosure [Abstract]
Income Taxes	, we had approximately $3.2 million in total gross unrecognized tax benefits. Of this amount $3.2 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 Disclosure [Abstract]

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 72% 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 September 30, 2020		As of December 31, 2019
Accrued expenses	$	37.0	$	38.2
Other liabilities	80.4		74.6
Total warranty liability	$	117.4	$	112.8

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

Total warranty liability as of December 31, 2019	$	112.8
Warranty claims paid	(26.9)
Changes resulting from issuance of new warranties	31.2
Changes in estimates associated with pre-existing liabilities	0.3
Changes in foreign currency translation rates and other	—
Total warranty liability as of September 30, 2020	$	117.4

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 (in millions):

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2020		2019		2020		2019
Expense (gain) for asbestos-related litigation, net	$	2.4	$	1.5	$	1.9	$	3.3

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.

Natural Disasters and Recovery

On July 19, 2018, our manufacturing facility in Marshalltown, Iowa was severely damaged by a tornado. On August 10, 2020, the Marshalltown facility was partially damaged by a derecho wind storm. The costs and losses incurred as well as any insurance recoveries for both of these natural disasters are shown in Loss (gain) from natural disasters, net of insurance recoveries in the Consolidated Statements of Operations.

The following table summarizes the components of Loss (gain) from natural disasters, net of insurance recoveries (in millions):

Marshalltown 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. 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.

Marshalltown Wind Storm

We have insurance for the repair and replacement of our assets that suffered damage or loss, and are working closely with our insurance carriers and claims adjusters to ascertain the amount of insurance recoveries due to us as a result of the damage and losses we suffered. Our insurance policies also provide business interruption coverage, including lost profits and reimbursement for other expenses and costs that have been incurred related to the damages and losses suffered.

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 September 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 $10.1 million during the nine months ended September 30, 2020 from employees who tendered their shares to satisfy minimum tax withholding obligations upon the vesting and exercise of stock-based compensation awards.

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 September 30,				For the Nine Months Ended September 30,

Segment Reporting, Measurement Disclosures [Abstract]

Reportable Business Segments

We operate in three reportable business segments of the heating, ventilation, air conditioning and refrigeration (“HVACR”) industry. Our segments are organized primarily by the nature of the products and services we provide. The following table describes each segment:

Segment	Product or Services	Markets Served	Geographic Areas
Residential Heating & Cooling	Furnaces, air conditioners, heat pumps, packaged heating and cooling systems, indoor air quality equipment, comfort control products, replacement parts and supplies	Residential Replacement; Residential New Construction	United States Canada
Commercial Heating & Cooling	Unitary heating and air conditioning equipment, applied systems, controls, installation and service of commercial heating and cooling equipment, and variable refrigerant flow commercial products	Light Commercial	United States Canada
Refrigeration	Condensing units, unit coolers, fluid coolers, air cooled condensers, air handlers, process chillers, controls, and compressorized racks	Light Commercial; Food Preservation; Non-Food/Industrial	United States Canada Europe

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 September 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 September 30, 2020		As of December 31, 2019
Senior unsecured notes	$	945.0	$	356.8

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited Consolidated Balance Sheet as of September 30, 2020, the accompanying unaudited Consolidated Statements of Operations for the three and nine months ended September 30, 2020 and 2019, the accompanying unaudited Consolidated Statements of Comprehensive Income for the three and nine months ended September 30, 2020 and 2019, the accompanying unaudited Consolidated Statements of Stockholders' Deficit for the three and nine months ended September 30, 2020 and 2019, and the accompanying unaudited Consolidated Statements of Cash Flows for the nine months ended September 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. For convenience, the 13-week periods comprising each fiscal quarter are denoted by the last day of the respective calendar quarter.

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 72% 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.
