LENNOX INTERNATIONAL INC.
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 June 30, 2021, the accompanying unaudited Consolidated Statements of Operations for the three and six months ended June 30, 2021 and 2020, the accompanying unaudited Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2021 and 2020, the accompanying unaudited Consolidated Statements of Stockholders' Deficit for the three and six months ended June 30, 2021 and 2020, and the accompanying unaudited Consolidated Statements of Cash Flows for the six months ended June 30, 2021 and 2020 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, 2020.
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”) has surfaced and spread around the world, including to the United States. In March 2020, the World Health Organization declared COVID-19 a pandemic. Currently the COVID-19 pandemic has disrupted our business operations and caused a significant unfavorable impact on our results of operations in 2020. The COVID-19 pandemic is creating supply chain disruptions and higher employee absenteeism in our factories and distribution locations.
As the COVID-19 pandemic continues, health concern risks remain. We cannot predict whether any of our manufacturing, operational or distribution facilities will experience disruptions, or how long such disruptions would last. It also remains
7

unclear how various national, state, and local governments will react if the distribution of vaccines is slower than expected or new variants of the virus become more dominant. If the COVID-19 pandemic worsens or the pandemic continues longer than presently expected, COVID 19 could impact our results of operations, financial position and cash flows.
Recently Adopted Accounting Guidance
In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-02, in an effort to reduce complexity in accounting for income taxes, removes certain exceptions for measuring intraperiod tax allocations, foreign subsidiary equity method investments and interim period tax losses. ASU 2019-12 is effective for calendar year-end public business entities on January 1, 2021. The adoption of ASU 2019-12 did not have a material impact on our financial statements.
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 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.

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.
9

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

| For the Three Months Ended June 30, |  | For the Six Months Ended June 30,
| 2021 |  | 2020 |  | 2021 |  | 2020
Net income | $ | 170.0 |  |  | $ | 100.0 |  |  | $ | 254.2 |  |  | $ | 112.9 |
Exclude: Income from discontinued operations | — |  |  | 0.6 |  |  | — |  |  | 0.2 |
Income from continuing operations | $ | 170.0 |  |  | $ | 100.6 |  |  | $ | 254.2 |  |  | $ | 113.1 |
Weighted-average shares outstanding – basic | 37.4 |  |  | 38.2 |  |  | 37.7 |  |  | 38.3 |
Add: Potential effect of dilutive securities attributable to stock-based payments | 0.3 |  |  | 0.2 |  |  | 0.3 |  |  | 0.3 |

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 June 30, |  | For the Six Months Ended June 30,
| 2021 |  | 2020 |  | 2021 |  | 2020

Price per share | $— |  | $205.53-$257.08 |  | $— |  | $205.53-$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.
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. 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
10

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 73% of our right-of-use assets and lease liabilities relate to our leases of real estate with the remaining amounts primarily 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 experience, as necessary.
Liabilities for estimated product warranty costs related to continuing operations are included in the following captions on the accompanying Consolidated Balance Sheets (in millions):

| As of June 30, 2021 |  | As of December 31, 2020
Accrued expenses | $ | 38.8 |  |  | $ | 37.7 |
Other liabilities | 93.0 |  |  | 82.1 |
Total warranty liability | $ | 131.8 |  |  | $ | 119.8 |

The changes in product warranty liabilities related to continuing operations for the six months ended June 30, 2021 were as follows (in millions):

Total warranty liability as of December 31, 2020 | $ | 119.8 |
Warranty claims paid | (15.5) |
Changes resulting from issuance of new warranties | 24.0 |
Changes in estimates associated with pre-existing liabilities | 3.5 |
Changes in foreign currency translation rates and other | — |
Total warranty liability as of June 30, 2021 | $ | 131.8 |

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
11

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 June 30, |  | For the Six Months Ended June 30,
| 2021 |  | 2020 |  | 2021 |  | 2020
Loss (gain) for asbestos-related litigation, net | $ | 1.7 |  |  | $ | 1.2 |  |  | $ | 2.8 |  |  | $ | (0.5) |

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.
5. Stock Repurchases:
Our Board of Directors has authorized a total of $3.0 billion to repurchase shares of our common stock (collectively referred to as the "Share Repurchase Plans"), including a $500 million share repurchase authorization in December 2019. Under this program, we may repurchase shares from time to time in open market transactions and in privately negotiated transactions based on business, market, applicable legal requirements and other considerations. The repurchase program does not require the repurchase of a specific number of shares and may be terminated at any time. As of June 30, 2021, $46 million was available for repurchase under the Share Repurchase Plans.
In July 2021, our Board of Directors authorized an additional $1.0 billion of share repurchases.
On February 4, 2021, we entered into a fixed dollar accelerated share repurchase transaction (the "ASR Agreement") with Wells Fargo Bank, to effect an accelerated stock buyback of the Company's common stock. Under the ASR Agreement, we paid Wells Fargo Bank $200.0 million and Wells Fargo Bank delivered to us common stock representing approximately 85% of the shares expected to be purchased under this ASR Agreement. The ASR was completed in April 2021 and Wells Fargo Bank delivered a total of 0.7 million shares of common stock repurchased under this ASR Agreement.
On May 3, 2021, we entered into an 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 $200.0 million and Bank of America delivered to us common stock representing approximately 85% of the shares expected to be purchased under this ASR Agreement. The ASR was completed in June 2021 and Bank of America delivered a total of 0.6 million shares of common stock repurchased under this ASR Agreement.
We also repurchased shares for $10.2 million during the six months ended June 30, 2021 from employees who tendered their shares to satisfy minimum tax withholding obligations upon the vesting and exercise of stock-based compensation awards.
6. Revenue Recognition:
The following table disaggregates our revenue by business segment by geography which provides information as to the major source of revenue. See Note 2 for additional information on our reportable business segments and the products and services sold in each segment.

Residential Heating & Cooling - We manufacture and market a broad range of furnaces, air conditioners, heat pumps, packaged heating and cooling systems, equipment and accessories to improve indoor air quality, comfort control products, replacement parts and supplies and related products for both the residential replacement and new construction markets in North America. These products are sold under various brand names and are sold either through direct sales to a network of independent installing dealers, including through our network of Lennox stores or to independent distributors. For the three months ended June 30, 2021 and 2020, direct sales represented 76% and 76% of revenues, and sales to independent distributors represented the remainder. For the six months ended June 30, 2021 and 2020, direct sales represented 72% and 75% of revenues, and sales to independent distributors represented the remainder. Given the nature of our business, customer product orders are fulfilled at a point in time and not over a period of time.
Commercial Heating & Cooling - In North America, we manufacture and sell unitary heating and cooling equipment used in light commercial applications, such as low-rise office buildings, restaurants, retail centers, churches and schools. These products are distributed primarily through commercial contractors and directly to national account customers in the planned replacement, emergency replacement and new construction markets. Revenue for the products sold is recognized at a point in time when control transfers to the customer, which is generally at time of shipment. Lennox National Account Services provides installation, service and preventive maintenance for HVAC national account customers in the United States and Canada. Revenue related to service contracts is recognized as the services are performed under the contract based on the relative fair value of the services provided. For the three months ended June 30, 2021 and 2020, equipment sales represented 85% and 86% of revenues and the remainder of our revenue was generated from our service business. For the six months ended June 30, 2021 and 2020, equipment sales represented 84% and 85% of revenues and the remainder of our revenue was generated from our service business.
Refrigeration - We manufacture and market equipment for the global commercial refrigeration markets under the Heatcraft Worldwide Refrigeration name. Our products are used in the food retail, food service, cold storage as well as non-food refrigeration markets. We sell these products to distributors, installing contractors, engineering design firms, original equipment manufacturers and end-users. In Europe, we also manufacture and sell unitary heating and cooling products and applied systems. Substantially all segment revenue was related to these types of equipment and systems and is recognized at a
13

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 liabilities consisted of the following:

| June 30, 2021 |  | December 31, 2020 |  | $ Change |  | % Change
Contract liabilities - current | $ | (6.5) |  |  | $ | (5.5) |  |  | $ | (1.0) |  |  | 18.2 | %
Contract liabilities - noncurrent | (5.7) |  |  | (5.6) |  |  | (0.1) |  |  | 1.8 | %
Total | $ | (12.2) |  |  | $ | (11.1) |  |  | $ | (1.1) |  |  |

For the three months ended June 30, 2021 and 2020, we recognized revenue of $0.8 million and $2.9 million and for the six months ended June 30, 2021 and 2020 we recognized revenue of $2.4 million and $4.5 million related to our contract liabilities at January 1, 2021 and 2020, respectively. Impairment losses recognized in our receivables and contract assets were de minimis in 2021 and 2020.

We monitor our reporting units for indicators of impairment throughout the year to determine if a change in facts or circumstances warrants a re-evaluation of our goodwill. We have not recorded any goodwill impairments for the six months ended June 30, 2021.
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 November 2022. 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
15

based on the prices of the commodities and foreign currencies at the settlement dates. We recorded the following amounts in AOCL related to our cash flow hedges (in millions):

| As of June 30, 2021 |  | As of December 31, 2020
Unrealized gains on unsettled contracts | $ | (17.6) |  |  | $ | (10.5) |
Income tax expense | 3.5 |  |  | 2.3 |
Gains included in AOCL, net of tax (1) | $ | (14.1) |  |  | $ | (8.2) |

(1) Assuming commodity prices and foreign currency exchange rates remain constant, we expect to reclassify $12.8 million of derivative gains as of June 30, 2021 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):

9. Income Taxes:
As of June 30, 2021, we had approximately $3.4 million in total gross unrecognized tax benefits. All of this amount, 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 2020 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 2014.

Short-Term Debt
Foreign Obligations
Through several of our foreign subsidiaries, we have facilities available to assist us in financing seasonal borrowing needs for our foreign locations. We had no outstanding foreign obligations as of June 30, 2021 or December 31, 2020 and there were no borrowings or repayments on these facilities during the six months ended June 30, 2021.
Asset Securitization Program
Under the Asset Securitization Program (“ASP”), we are eligible to sell beneficial interests in a portion of our trade accounts receivable to a financial institution for cash. The ASP contains a provision whereby we retain the right to repurchase all of the outstanding beneficial interests transferred. As a result of the repurchase right, the transfer of the receivables under the ASP is not accounted for as a sale. Accordingly, the cash received from the transfer of the beneficial interests in our trade accounts receivable is reflected as secured borrowings in the accompanying Consolidated Balance Sheets and proceeds received are included in Cash flows from financing activities in the accompanying Consolidated Statements of Cash Flows. Our continued involvement with the transferred assets includes servicing, collection and administration of the transferred beneficial interests. The accounts receivable securitized under the ASP are high-quality domestic customer accounts that have not aged significantly. The receivables represented by the retained interest that we service are exposed to the risk of loss for any uncollectible amounts in the pool of receivables transferred under the ASP.
We renewed the ASP in November 2019, extending its term to November 2021 and increasing the maximum securitization amount to a range from $250.0 million to $400.0 million, depending on the period. The maximum capacity under the ASP is the lesser of the maximum securitization amount or 100% of the net pool balance less allowances, as defined by the ASP. Eligibility for securitization is limited based on the amount and quality of the qualifying accounts receivable and is calculated monthly. The eligible amounts available and beneficial interests sold were as follows (in millions):

| As of June 30, 2021 |  | As of December 31, 2020
Eligible amount available under the ASP on qualified accounts receivable | $ | 320.0 |  |  | $ | 279.1 |
Less: Beneficial interest transferred | (255.0) |  |  | — |
Remaining amount available | $ | 65.0 |  |  | $ | 279.1 |

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 interests sold and calculated on either the average LIBOR rate or floating commercial paper rate determined by the purchaser of the beneficial interest, plus a program fee of 0.70%. The average rates as of June 30, 2021 and December 31, 2020 were 0.80% and zero%, respectively. The unused fee is
17

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 existing 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 existing credit facility. The participating financial institutions have investment grade credit ratings. As of June 30, 2021, we believe we were in compliance with all covenant requirements.
Long-Term Debt
Domestic Credit Facility
The Seventh Amended and Restated Credit Facility (the "Prior Credit Agreement") consisted of a $750.0 million unsecured revolving credit facility and was set to mature in August 2022. We had outstanding borrowings of $4.5 million as well as $2.2 million committed to standby letters of credit as of June 30, 2021. Subject to covenant limitations, $743.3 million was available for future borrowings. The Prior Credit Agreement included a subfacility for swingline loans of up to $65.0 million.
Our weighted average borrowing rate on the facility was as follows:

| As of June 30, 2021 |  | As of December 31, 2020
Weighted average borrowing rate | 1.63 | % |  | — | %

In July 2021, we entered into a new Credit Agreement (the “Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent, and the other lenders party thereto, which refinanced and replaced the Prior Credit Agreement, among the Company, JPMorgan Chase Bank, N.A., as administrative agent, and the other lenders party thereto.
The Credit Agreement provides for revolving credit commitments of $750 million with sublimits for swingline loans of up to $65 million, letters of credit up to $100 million and revolving loans in certain non-U.S. currencies up to the U.S. dollar equivalent of $40 million. The Credit Agreement will expire and outstanding loans will be required to be repaid in July 2026, unless maturity is extended by the lenders pursuant to two one-year extension options that we may request under the Credit Agreement. At our request and subject to certain conditions, the revolving credit commitments under the Credit Agreement may be increased by up to a total of $350 million to the extent that existing or new lenders agree to provide additional commitments.
The Credit Agreement is guaranteed by certain of our subsidiaries and contains customary covenants applicable to us and our subsidiaries including limitations on indebtedness, liens, dividends, stock repurchases, mergers and sales of all or substantially all of our assets. In addition, the Credit Agreement contains a financial covenant requiring us to maintain, as of the last day of each fiscal quarter for the four prior fiscal quarters, a Total Net Leverage Ratio of no more than 3.50 to 1.00 (or, at our election, on up to two occasions following a material acquisition, 4.00 to 1.00). The Credit Agreement is subject to customary events of default, including non-payment of principal or other amounts under the Credit Agreement, material inaccuracy of representations and warranties, breach of covenants, cross-default to other indebtedness in excess of $75 million, judgements in excess of $75 million, certain voluntary and involuntary bankruptcy events, and the occurrence of a change of control. As of June 30, 2021, we believe we were in compliance with all covenant requirements.
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 Credit Agreement. The indenture governing the Notes contains covenants that, among other things, limit our ability and the ability of the subsidiary guarantors to: create or incur certain liens; enter into certain sale and leaseback transactions; and enter into certain mergers, consolidations and transfers of substantially all of our assets. The indenture also contains a cross default provision which is triggered if we default on other debt of at least $75.0 million in principal which is then accelerated, and such acceleration is not rescinded within 30 days of the notice date. As of June 30, 2021, we believe we were in compliance with all covenant requirements.

12. Fair Value Measurements:
Fair Value Hierarchy
The methodologies used to determine the fair value of our financial assets and liabilities at June 30, 2021 were the same as those used at December 31, 2020.
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 7 for more information related to our derivative instruments.
19

Other Fair Value Disclosures
The carrying amounts of Cash and cash equivalents, Short-term investments, Accounts and notes receivable, net, Accounts payable, and Short-term debt approximate fair value due to the short maturities of these instruments. The carrying amount of our Domestic Credit Facility in Long-term debt also approximates fair value due to its variable-rate characteristics.
The fair value of our senior unsecured notes in Long-term debt, classified as Level 2, was based on the amount of future cash flows using current market rates for debt instruments of similar maturities and credit risk. The following table presents their fair value (in millions):

| As of June 30, 2021 |  | As of December 31, 2020
Senior unsecured notes | $ | 977.2 |  |  | $ | 971.6 |

13. Subsequent Event:
On July 8, 2021, Todd M. Bluedorn, our Chairman of the Board and Chief Executive Officer advised our Board of Directors that he intended to resign as Chief Executive Officer and as Chairman and a member of our Board of Directors in mid-2022.
The Board of Directors has commenced a search for our next chief executive officer.

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, 2020, 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
A novel strain of coronavirus (“COVID-19”) has surfaced and spread around the world, including to the United States. In March 2020, the World Health Organization declared COVID-19 a pandemic. Currently the COVID-19 pandemic has disrupted our business operations and caused a significant unfavorable impact on our results of operations in 2020. The COVID-19 pandemic is creating supply chain disruptions and higher employee absenteeism in our factories and distribution locations.
As the COVID-19 pandemic continues, health concern risks remain. We cannot predict whether any of our manufacturing, operational or distribution facilities will experience disruptions, or how long such disruptions would last. It also remains
21

unclear how various national, state, and local governments will react if the distribution of vaccines is slower than expected or new variants of the virus become more dominant. If the COVID-19 pandemic worsens or the pandemic continues longer than presently expected, COVID 19 could impact our results of operations, financial position and cash flows.
Financial Overview
Results for the second quarter of 2021 were driven by year over year sales and profit increases across all of our business segments. The Residential Heating & Cooling segment saw a 30% increase in net sales and a $62 million increase in segment profit. The Commercial Heating & Cooling segment had a 34% increase in net sales and a $10 million increase in segment profit. The Refrigeration segment had a 37% increase in net sales and a $5 million increase in segment profit.
Financial Highlights
•Net sales increased $298 million to $1,239 million in the second quarter of 2021 driven by net volume increases and favorable price and mix.
•Operating income in the second quarter of 2021 increased $80 million to $216 million primarily driven by higher net sales and an improved gross margin percentage partially offset by higher SG&A costs.
•Net income for the second quarter of 2021 increased $70 million to $170 million.
•Diluted earnings per share from continuing operations were $4.51 per share in the second quarter of 2021 compared to $2.62 per share in the second quarter of 2020.
•For the six months ended June 30, 2021, we returned $59 million to shareholders through dividend payments and repurchased $400 million of common stock through our share repurchase program.

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 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 second quarter of 2021 was down slightly compared to the second quarter of 2020.
Interest Expense, net
Interest expense, net was down $1 million to $6 million in the second quarter of 2021 from $7 million in the second quarter of 2020 due to lower borrowing costs.
23

Income Taxes
Our effective tax rate was 18.6% for the second quarter of 2021 compared to 21.4% for the second quarter of 2020. The rate decreased primarily due to an increase in excess tax benefits from stock based compensation.
We expect our annual effective tax rate in 2021 to be approximately 2 0%, after excluding the impacts of excess tax benefits recorded under ASU No. 2016-0 9.

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 six months ended June 30, 2021 and 2020 (in millions):

| For the Six Months Ended June 30,

Net Cash Provided by Operating Activities - The change in net cash used in operating activities for the six months ended June, 2021 compared to the same period in 2020 reflects an increase in operating income and favorable changes in working capital.
Net Cash Used in Investing Activities - Capital expenditures were $46 million in the six months ended June 30, 2021 compared to $44 million in the same period of 2020. Capital expenditures in 2021 were primarily related to the expansion of manufacturing capacity and equipment, and investments in systems and software to support the overall enterprise.
Net Cash (Used in) provided by Financing Activities - Net cash (used in) provided by financing activities in the six months ended June 30, 2021 changed to a net use of cash of $211 million compared to a net cash inflow of $52 million in the same period of 2020.

July 2021 Credit Agreement
In July 2021, we entered into the Credit Agreement (the “Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent, and the other lenders party thereto, which refinanced and replaced the Prior Credit Agreement, among the Company, JPMorgan Chase Bank, N.A., as administrative agent, and the other lenders party thereto.
The Credit Agreement provides for revolving credit commitments of $750 million with sublimits for swingline loans of up to $65 million, letters of credit up to $100 million and revolving loans in certain non-U.S. currencies up to the U.S. dollar equivalent of $40 million. The Credit Agreement will expire and outstanding loans will be required to be repaid in July 2026, unless maturity is extended by the lenders pursuant to two one-year extension options that we may request under the Credit Agreement. At our request and subject to certain conditions, the revolving credit commitments under the Credit Agreement may be increased by up to a total of $350 million to the extent that existing or new lenders agree to provide additional commitments.
The Credit Agreement is guaranteed by certain of our subsidiaries and contains customary covenants applicable to us and its subsidiaries including limitations on indebtedness, liens, dividends, stock repurchases, mergers and sales of all or substantially all of its assets. In addition, the Credit Agreement contains a financial covenant requiring us to maintain, as of the last day of each fiscal quarter for the four prior fiscal quarters, a Total Net Leverage Ratio of no more than 3.50 to 1.00 (or, at our election, on up to two occasions following a material acquisition, 4.00 to 1.00). The Credit Agreement is subject to customary events of default, including non-payment of principal or other amounts under the Credit Agreement, material inaccuracy of representations and warranties, breach of covenants, cross-default to other indebtedness in excess of $75 million, judgements in excess of $75 million, certain voluntary and involuntary bankruptcy events, and the occurrence of a change of control.
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 121% at June 30, 2021 from 102% at December 31, 2020.
29

As of June 30, 2021, our senior credit ratings were Baa2 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 $45 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 $45 million as of June 30, 2021 was $20 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.
In connection with the Credit Agreement we entered into in July 2021, Heatcraft Technologies Inc., Lennox National Account Services Inc., Lennox Procurement Company Inc. and Lennox Services LLC became additional guarantors of our debt obligations, guaranteeing the payment when due of all monetary obligations under the Credit Agreement and the Notes. In addition, Lennox Switzerland GmbH was released as a guarantor of all monetary obligations under the Credit Agreement and the Notes. These changes did not result in a material change to the Parent and Guarantor Subsidiaries financial information.
Off Balance Sheet Arrangements
An off-balance sheet arrangement is any transaction, agreement or other contractual arrangement involving an unconsolidated entity under which the company has: (1) made guarantees, (2) a retained or a contingent interest in transferred assets, (3) an obligation under derivative instruments classified as equity or (4) any obligation arising out of a material variable interest in an unconsolidated entity that provides financing, liquidity, market risk or credit risk support to us, or that engages in leasing, hedging or research and development arrangements with us. We have no off-balance sheet arrangements that we believe may have a material current or future effect on our financial condition, liquidity or results of operations.

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 June 30, 2021, 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, 2020, 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, 2020 and in Form 10-Q for the quarter ended March 31, 2021.
