NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2021
(unaudited)
1.    Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and footnotes required for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results expected for the full year. It is suggested the accompanying condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on February 12, 2021.
Recent Accounting Pronouncement
In December 2019, the Financial Accounting Standards Board (FASB) amended Accounting Standards Codification (ASC) 740, Income Taxes (issued under Accounting Standards Update (ASU) 2019-12, “Simplifying the Accounting for Income Taxes”). This amendment removed certain exceptions to the general principles of ASC 740 and clarified and amended existing guidance to improve consistent application. The Company adopted the amendment on January 1, 2021, and the adoption of ASU 2019-12 did not have an impact on its consolidated balance sheets, statements of earnings or statements of cash flows.
2.    Revenue Recognition
Substantially all of the Company’s sales are from contracts with customers for the purchase of its products. Contracts and customer purchase orders are used to determine the existence of a sales contract. Shipping documents are used to verify shipment. For substantially all of its products, the Company transfers control of products to the customer at the point in time when title and risk are passed to the customer, which generally occurs upon shipment of the product. Each unit sold is considered an independent, unbundled performance obligation. The Company’s sales arrangements do not include other performance obligations that are material in the context of the contract.
The nature, timing and amount of revenue for a respective performance obligation are consistent for each customer. The Company measures the sales transaction price based upon the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. Sales and value added taxes are excluded from the measurement of the transaction price. The Company’s payment terms for the majority of its customers are 30 to 90 days from shipment.
Additionally, certain customers in China pay the Company prior to the shipment of products resulting in a customer deposits liability of $100.4 million and $90.0 million at September 30, 2021 and December 31, 2020, respectively. Customer deposit liabilities are short term in nature and deposits are recognized into revenue within one year of receipt. The Company assesses the collectability of customer receivables based on the creditworthiness of a customer as determined by credit checks and analysis, as well as the customer’s payment history. In determining the allowance for doubtful accounts, the Company also considers various factors including the aging of customer accounts and historical write-offs. In addition, the Company monitors other risk factors including forward-looking information when establishing adequate allowances for doubtful accounts, which reflects the current estimate of credit losses expected to be incurred over the life of the receivables. The Company’s allowance for doubtful accounts was $10.1 million at September 30, 2021 and $5.6 million at December 31, 2020.
Rebates and incentives are based on pricing agreements and are tied to sales volume. The amount of revenue is reduced for variable consideration related to customer rebates which are calculated using expected values and are based on program specific factors such as expected rebate percentages based on expected volumes. In situations where the customer has the right to return eligible products, the Company reduces revenue for its estimates of expected product returns, which are primarily based on an analysis of historical experience. Changes in such accruals may be required if actual sales volume differs from estimated sales volume or if future returns differ from historical experience. Shipping and handling costs billed to customers are included in net sales and the related costs are included in cost of products sold and are activities performed to fulfill the promise to transfer products.

2.    Revenue Recognition (continued)
Disaggregation of Net Sales
The Company is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, Europe and India. Both segments manufacture and market comprehensive lines of residential and commercial gas and electric water heaters, boilers, tanks and water treatment products. Both segments primarily manufacture and market in their respective regions of the world.
As each segment manufactures and markets products in its respective region of the world, the Company has determined that geography is the primary factor in reporting its sales. The Company further disaggregates its North America segment sales by major product line as each of North America’s major product lines is sold through distinct distribution channels and these product lines may be impacted differently by certain economic factors. Within the Rest of World segment, particularly in China and India, the Company’s major customers purchase across the Company’s product lines, utilizing the same distribution channels regardless of product type. In addition, the impact of economic factors is unlikely to be differentiated by product line in the Rest of World segment.
The North America segment major product lines are defined as the following:
Water heaters The Company’s water heaters are open water heating systems that heat potable water. Typical applications for water heaters include residences, restaurants, hotels and motels, office buildings, laundries, car washes and small businesses. The Company sells residential and commercial water heater products and related parts through its wholesale distribution channel, which includes more than 1,200 independent wholesale plumbing distributors. The Company also sells residential water heaters and related parts through retail and maintenance, repair and operations (MRO) channels. A significant portion of the Company’s water heater sales in the North America segment is derived from the replacement of existing products.
Boilers The Company’s boilers are closed loop water heating systems used primarily for space heating or hydronic heating. The Company’s boilers are primarily used in applications in commercial settings for hospitals, schools, hotels and other large commercial buildings while residential boilers are used in homes, apartments and condominiums. The Company’s boiler distribution channel is comprised primarily of manufacturer representative firms, with the remainder of its boilers distributed through wholesale channels. The Company’s boiler sales in the North America segment are derived from a combination of replacement of existing products and new construction.
Water treatment products The Company’s water treatment products range from point-of-entry water softeners, solutions for problem well water, and whole-home water filtration products to on-the-go filtration bottles and point-of-use carbon and reverse osmosis products. Typical applications for the Company’s water treatment products include residences, restaurants, hotels and offices. The Company sells water treatment products through its retail and wholesale distribution channels, similar to water heater products and related parts. The Company’s water treatment products are also sold through independent water quality dealers as well as directly to consumers including through internet sales channels. A portion of the Company’s sales of water treatment products in the North America segment is comprised of replacement filters.
The following table disaggregates the Company’s net sales by segment. As described above, the Company’s North America segment sales are further disaggregated by major product line. In addition, the Company’s Rest of World segment sales are disaggregated by China and all other Rest of World:

3.    Severance and Restructuring Expenses
To align its business to market conditions, during the three and nine months ended September 30, 2020, the Company recognized $1.6 million and $7.7 million of pre-tax severance and restructuring expenses, respectively. Charges recognized during the three months ended September 30, 2020, were comprised of $1.6 million severance costs, as well as a corresponding $0.3 million tax benefit related to these expenses. Charges recognized during the nine months ended September 30, 2020, were comprised of $6.8 million severance costs and $0.9 million of other restructuring expenses, as well as a corresponding $1.4 million tax benefit related to these expenses. Of the $1.6 million expense recognized during the three months ended September 30, 2020, $0.5 million was related to the North America segment and $1.1 million was related to the Rest of World segment. Of the $7.7 million expense recognized during the nine months ended September 30, 2020, $2.7 million was related to the North America segment and $5.0 million was related to the Rest of World segment. The Company’s severance and restructuring actions were primarily completed in the nine months ended September 30, 2020.
4.    Leases
The Company’s lease portfolio consists of operating leases for buildings and equipment, such as forklifts and copiers, primarily in the United States and China. The Company defines a lease as a contract that gives the Company the right to control the use of a physical asset for a stated term. The Company pays the lessor for that right, with a series of payments defined in the contract and a corresponding right of use operating lease asset and liability are recorded. The Company has elected not to record leases with an initial term of 12 months or less on its condensed consolidated balance sheet. To determine balance sheet amounts, required legal payments are discounted using the Company’s incremental borrowing rate as of the inception of the lease. The incremental borrowing rate is the rate of interest that the Company would incur if it were to borrow, on a collateralized basis, an amount equal to the value of the leased item over a similar term, in a similar economic environment. Variable lease components not based on an index or rate are excluded from the measurement of the lease asset and liability and expensed as incurred for all asset classes.
Certain leases include one or more options to renew or terminate. Renewal terms can extend the lease term from one to five years and options to terminate can be effective within one year. The exercise of lease renewal or termination is at the Company’s discretion and when it is determined to be reasonably certain to renew or terminate, the option is reflected in the measurement of lease asset and liability. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants or material subleases. Cash flows associated with leases are materially consistent with the expense recorded in the condensed consolidated statement of earnings.

Borrowings under bank credit lines and commercial paper borrowings are supported by a $500 million revolving credit agreement. At its option, the Company either maintains cash balances or pays fees for bank credit and services. The Company did not have borrowings on this facility as of September 30, 2021.

The Company adopted the A. O. Smith Combined Incentive Compensation Plan (the Plan) effective January 1, 2007. The Plan was most recently reapproved by stockholders on April 15, 2020. The Plan is a continuation of the A. O. Smith Combined Executive Incentive Compensation Plan which was originally approved by stockholders in 2002. The number of shares available for granting of options or share units at September 30, 2021 was 6,782,565. Upon stock option exercise or share unit vesting, shares are issued from treasury stock.

Table of Contents
9.    Stock Based Compensation (continued)
Stock Options
The stock options granted in the nine months ended September 30, 2021 and 2020 have three year pro rata vesting from the date of grant. Stock options are issued at exercise prices equal to the fair value of the Company’s Common Stock on the date of grant. For active employees, all options granted in 2021 and 2020 expire ten years after the date of grant. The Company’s stock options are expensed ratably over the three year vesting period; however, included in stock option expense for the nine months ended September 30, 2021 and 2020 was expense associated with the accelerated vesting of stock option awards for certain employees who either are retirement eligible or become retirement eligible during the vesting period. Stock based compensation expense attributable to stock options in the three months ended September 30, 2021 and 2020 was $0.5 million and $0.5 million, respectively. Stock based compensation expense attributable to stock options in the nine months ended September 30, 2021 and 2020 was $4.6 million and $5.7 million, respectively.

The weighted-average fair value per option at the date of grant during the nine months ended September 30, 2021 and 2020 using the Black-Scholes option-pricing model was $14.03 and $8.17, respectively. Assumptions were as follows:

Expected life (years)5.85.7
Risk-free interest rate1.2 %1.5 %
Dividend yield1.6 %2.1 %
Expected volatility27.4 %23.7 %
The expected lives of options for purposes of these models are based on historical exercise behavior. The risk-free interest rates for purposes of these models are based on the U.S. Treasury yield curve in effect on the date of grant for the respective expected lives of the option. The expected dividend yields for purposes of these models are based on the dividends paid in the preceding four quarters divided by the grant date market value of the Common Stock. The expected volatility for purposes of these models are based on the historical volatility of the Common Stock.
Restricted Stock and Share Units
Participants may also be awarded shares of restricted stock or share units under the Plan. Share units vest three years after the date of grant. The Company granted 104,223 and 172,426 share units under the Plan in the nine months ended September 30, 2021 and 2020, respectively. The share units were valued at $6.4 million and $7.3 million at the date of issuance in 2021 and 2020, respectively, based on the price of the Company’s Common Stock at the date of grant. The share units are recognized as compensation expense ratably over the three-year vesting period; however, included in share unit expense in the three and nine months ended September 30, 2021 and 2020 was expense associated with accelerated vesting of share unit awards for certain employees who either are retirement eligible or will become retirement eligible during the vesting period. Stock based compensation expense attributable to share units of $0.9 million and $0.6 million was recognized in the three months ended September 30, 2021 and 2020, respectively. Stock based compensation expense attributable to share units of $5.7 million and $5.8 million was recognized in the nine months ended September 30, 2021

12.    Fair Value Measurements
ASC 820, Fair Value Measurements, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Assets and liabilities measured at fair value are based on the market approach which are prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.
The following table presents assets (liabilities) measured at fair value on a recurring basis (dollars in millions):

Items measured at fair value were comprised of the Company’s marketable securities (Level 1) and derivative instruments (Level 2). There were no changes in the Company’s valuation techniques used to measure fair values on a recurring basis during the nine months ended September 30, 2021.

13.    Derivative Instruments
The Company utilizes certain derivative instruments to enhance its ability to manage currency exposure as well as raw materials price risk. Derivative instruments are entered into for periods consistent with the related underlying exposures and do not constitute positions independent of those exposures. The Company does not enter into contracts for speculative purposes. The contracts are executed with major financial institutions with no credit loss anticipated for failure of the counterparties to perform.
Cash Flow Hedges
With the exception of its net investment hedges, the Company designates all of its hedging instruments as cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), gains or losses on the derivative instrument are reported as a component of other comprehensive loss, net of tax, and are reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings.
Foreign Currency Forward Contracts
The Company is exposed to foreign currency exchange risk as a result of transactions in currencies other than the functional currency of certain subsidiaries. The Company utilizes foreign currency forward purchase and sale contracts to manage the volatility associated with foreign currency purchases, sales and certain intercompany transactions in the normal course of business. Principal currencies for which the Company utilizes foreign currency forward contracts include the British pound, Canadian dollar, Euro and Mexican peso.
Gains and losses on these instruments are recorded in accumulated other comprehensive loss, net of tax, until the underlying transaction is recorded in earnings. When the hedged item is realized, gains or losses are reclassified from accumulated other comprehensive loss to the consolidated statement of earnings. The assessment of effectiveness for forward contracts is based on changes in the forward rates. These hedges have been determined to be effective. The majority of the amounts in accumulated other comprehensive loss for cash flow hedges are expected to be reclassified into earnings within one year.
The following table summarizes, by currency, the contractual amounts of the Company’s foreign currency forward contracts that are designated as cash flow hedges:
(dollars in millions)September 30, 2021December 31, 2020
BuySellBuySell
British pound$— $0.2 $— $1.0

Euro30.4 — 32.7 — 
Mexican peso28.2 — 16.5 — 
Total$58.6 $65.1 $49.2 $80.7 
Commodity Futures Contracts
In addition to entering into supply arrangements in the normal course of business, the Company also enters into futures contracts to fix the cost of certain raw material purchases, principally steel, with the objective of minimizing changes in cost due to market price fluctuations. The hedging strategy for achieving this objective is to purchase steel futures contracts on the New York Metals Exchange (NYMEX) and copper futures contracts on the open market of the London Metals Exchange (LME) or over the counter contracts based on the LME.
With NYMEX, the Company is required to make cash deposits on unrealized losses on steel derivative contracts.
The after-tax gains and losses on the contracts as of September 30, 2020 were recorded in accumulated other comprehensive loss and will be reclassified into cost of products sold in the period in which the underlying transaction is recorded in earnings. The after-tax gains and losses on the contracts will be reclassified within one year.
Net Investment Hedges
The Company enters into certain foreign currency forward contracts to hedge the exposure to a portion of the Company’s net investments in certain non-U.S. subsidiaries against the effect of exchange rate fluctuations on the translation of foreign currency balances to the U.S. dollar. For the derivative instruments that are designated and qualify as net investment
15

Table of Contents
13.    Derivative Instruments (continued)
hedges, gains and losses are reported in other comprehensive loss where they offset gains and losses recorded on the Company’s net investments in its non-U.S. subsidiaries. These hedges are determined to be effective. The Company recognized $ and $(0.1) million of after-tax losses associated with hedges of a net investment in non-U.S. subsidiaries in currency translation adjustment in other comprehensive income in both the three and nine months ended September 30, 2021, respectively. The Company recognized $(0.8) million and $(0.1) million of after-tax losses associated with hedges of a net investment in non-U.S. subsidiaries in currency translation adjustment in other comprehensive income in the three and nine months ended September 30, 2020, respectively. The contractual amount of the Company's foreign currency forward contracts that are designated as net investment hedges is $25.0 million as of September 30, 2021.

14.    Income Taxes
The Company’s effective income tax rate for the three and nine months ended September 30, 2021 was 20.9 percent and 21.7 percent, respectively. The Company estimates that its annual effective income tax rate for the full year 2021 will be approximately 22.0 percent. The effective income tax rate for the three and nine months ended September 30, 2020 was 23.2 percent and 23.0 percent, respectively. The change in the effective income tax rate for the three and nine months ended September 30, 2021 compared to the effective income tax rate for the three and nine months ended September 30, 2020 was primarily due to a change in geographical earnings mix as well as a favorable tax impact of $4.2 million related to amending a previously filed tax return.
As of September 30, 2021, the Company had $9.0 million of unrecognized tax benefits of which $0.5 million would affect its effective income tax rate if recognized. The Company recognizes potential interest and penalties related to unrecognized tax benefits as a component of income tax expense. The Company’s U.S. federal income tax returns for 2017-2021 are

14.    Income Taxes (continued)
subject to audit. The Company is subject to state and local income tax audits for tax years 2002-2021. The Company is subject to non-U.S. income tax examinations for years 2015-2021.
15.    Commitments and Contingencies
The Company maintains a commercial relationship with a supply-chain service provider (the Provider) in connection with the Company’s business in China. In this capacity, the Provider offers order-entry, warehousing and logistics support. The Provider also offers asset-backed financing to certain of the Company’s distributors in China to facilitate their working capital needs. To facilitate its financing support business, the Provider has collateralized lending facilities in place with multiple Chinese banks under which the Company has agreed to repurchase inventory if both requested by the banks and certain defined conditions are met, primarily related to the aging of the distributors’ notes.
The Provider is required to indemnify the Company for any losses the Company would incur in the event of an inventory repurchase under these arrangements. Potential losses under the repurchase arrangements represent the difference between the repurchase price and net proceeds from the resale of product plus costs incurred in the process, less related distributor rebates.
Before considering any reduction of distributor rebate accruals of $4.0 million and $5.4 million as of September 30, 2021 and December 31, 2020, respectively, and from the resale of the related inventory, the gross amount the Company would be obligated to repurchase, which would be contingent on the default of all of the outstanding loans, was approximately $7.7 million as of September 30, 2021 and $6.5 million as of December 31, 2020. The Company’s reserves for estimated losses under repurchase arrangements were immaterial as of September 30, 2021 and December 31, 2020.

17.    Subsequent Event
On October 19, 2021, the Company acquired Giant Factories, Inc. (Giant), a Canada-based manufacturer of residential and commercial water heaters. The purchase price was approximately $192.0 million, subject to customary adjustments. Giant manufactures water heaters at two facilities in Montreal, Canada and sells water heating products under the Giant brand across Canada. Giant had trailing twelve-month annual sales of approximately $105 million.

ITEM 2 - MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
OVERVIEW
Our company is comprised of two reporting segments: North America and Rest of World. Our Rest of World segment is primarily comprised of China, Europe and India. Both segments manufacture and market comprehensive lines of residential and commercial gas and electric water heaters, boilers, tanks, and water treatment products. Both segments primarily manufacture and market in their respective region of the world.
In January 2020, an outbreak of a novel coronavirus (COVID-19) surfaced in Wuhan, China. As a result of the outbreak, the Chinese government required businesses to close and restricted certain travel within the country. In March 2020, COVID-19 was declared a global pandemic and we experienced impacts to our business and other markets worldwide. As a result of the COVID-19 pandemic and in support of continuing our manufacturing efforts, we have undertaken numerous and meaningful steps to protect our employees, suppliers, and customers. As we continue to receive guidance from governmental authorities, we adjust our safety measures to meet or exceed those guidelines.
Our global supply chain management team continued to navigate through supply chain and logistics challenges. We have seen supply constraints for certain components and raw materials used in our operations, as well as limited container and trucking capacity, and port congestion and delays. We expect those challenges to continue for the foreseeable future and we remain in close communication with our suppliers.
In our North America segment, we expect residential water heater industry volumes will increase approximately six percent in 2021 compared with 2020, driven by continued growth in replacement demand and new home construction. We believe that commercial water heater industry volumes will increase approximately ten percent in 2021 as pandemic-impacted businesses continue to re-open and new construction and replacement installations increase. We continue to experience significant inflation across our supply chain, particularly steel and logistics costs. In response to continued material and logistics cost increases, we have implemented price increases, including our announced fifth price increase in 2021 on water heaters in September, effective on November 15, 2021. When fully realized at the end of 2021, the five announced inflation-related price increases on water heaters compound to approximately 50 percent. We expect our boiler sales to grow by approximately 13 percent in 2021 compared to 2020 due to pandemic-related pent-up demand as well as our new product introductions. We expect sales of our North America water treatment products to increase by approximately 12 percent in 2021, compared to 2020, primarily driven by consumer demand for our point of use and point of entry water treatment systems.
In our Rest of World segment, we expect China sales in 2021 to increase 20 to 22 percent in local currency terms compared with 2020 due to higher volumes and increased consumer demand for our higher priced products across all of our product categories driven by differentiated new products we launched in the last 12 to 24 months. Our sales in China were negatively impacted by COVID-19 pandemic related shutdowns in 2020. We assume China currency rates will stay at current levels and add approximately $54 million and $4 million to sales and earnings in 2021, respectively.

RESULTS OF OPERATIONS
THIRD QUARTER AND FIRST NINE MONTHS OF 2021 COMPARED TO 2020
Sales in the third quarter of 2021 were $915 million, or approximately 20 percent higher than sales of $760 million in the third quarter of 2020. Sales in the first nine months of 2021 were $2,543 million or approximately 23 percent higher than sales of $2,061 million in the same period last year. Both periods in 2020 were negatively impacted by the COVID-19 pandemic. Our sales increases in the third quarter and first nine months of 2021 compared to the same periods of the previous year were primarily driven by inflation-related pricing actions and higher water heater, boiler, and water treatment volumes in North America as well as higher sales in China. Our sales in China also benefited from currency translation of approximately $14 million and $49 million in the third quarter and first nine months of 2021, respectively, due to the appreciation of the Chinese currency against the U.S. Dollar.
Gross profit margin in the third quarter of 2021 was 37.2 percent compared to gross profit margin of 39.1 percent in the same period last year. Gross profit margin in the first nine months of 2021 was 37.4 percent compared to the gross profit margin of 38.0 percent in the first nine months of 2020. The lower gross margin in both periods of 2021 compared to 2020 was primarily due to higher steel and other material costs which outpaced our pricing actions.

Selling, general, and administrative (SG&A) expenses in the third quarter and first nine months of 2021 increased by $18.2 million and $28.1 million, respectively, compared to the prior-year periods. The increase in SG&A expenses in the third quarter and first nine months of 2021 was primarily due to higher advertising, engineering and selling expenses and higher
19

Table of Contents
management incentive expenses related to higher earnings compared to the same periods last year. Higher SG&A expenses in both the third quarter and first nine months of 2021 were partially offset by lower spending in China associated with headcount reductions, store closures and other cost-saving measures previously implemented during 2020.
During the third quarter and first nine months of 2020, aligning our business to market conditions, we recognized $1.6 million and $7.7 million, respectively, of pre-tax severance and restructuring expenses. These expenses were primarily comprised of $1.6 million of severance expenses in the third quarter of 2020 and $6.8 million of severance costs and $0.9 million of other restructuring expenses in the first nine months of 2020. These activities are reflected in “severance and restructuring expenses” in the accompanying financial statements.
We are providing non-GAAP measures (adjusted earnings, adjusted earnings per share, and adjusted segment earnings) that exclude severance and restructuring expenses. Reconciliations to measures on a GAAP basis are provided later in this section. We believe that the measures of adjusted earnings, adjusted EPS and adjusted segment earnings provide useful information to investors about our performance and allow management and our investors to better compare our performance period over period.
Interest expense in the third quarter of 2021 was $1.0 million compared to $1.6 million in the same period last year. Interest expense in the first nine months of 2021 was $2.9 million compared to $6.3 million in the same period the previous year. The decrease in interest expense in the third quarter and first nine months of 2021 compared to the same periods last year was primarily due to lower debt levels.
Other income was $4.7 million in the third quarter of 2021, higher than $2.8 million in the same period last year. Other income in the first nine months of 2021 was $13.6 million compared to $11.0 million in the first nine months of 2020. The increase in other income in the third quarter and first nine months of 2021 compared to the same periods last year was primarily due to higher pension income. The third quarter of 2021 also benefited from higher interest income.
Our pension costs and credits are developed from actuarial valuations. The valuations reflect key assumptions regarding, among other things, discount rates, expected return on plan assets, retirement ages, and years of service. We consider current market conditions, including changes in interest rates, in making these assumptions. Our assumption for the expected rate of return on plan assets is 6.25 percent in 2021 compared to 6.75 percent in 2020. The discount rate used to determine net periodic pension costs decreased to 2.45 percent in 2021 from 3.18 percent in 2020. Pension income for the third quarter and first nine months of 2021 was $2.9 million and $8.7 million, respectively, compared to $1.8 million and $5.9 million in the third quarter and first nine months of 2020, respectively. The service cost component of our pension income is reflected in cost of products sold and SG&A expenses. All other components of our pension income are reflected in other income.
Our effective income tax rates for the third quarter and first nine months of 2021 were 20.9 percent and 21.7 percent, respectively. Our effective income tax rates for the third quarter and first nine months of 2020 were 23.2 percent and 23.0 percent, respectively. Our effective income tax rates in the third quarter and first nine months of 2021 were lower than the effective income tax rates in the same periods of 2020 primarily due to a change in geographic earnings mix as well as a favorable tax impact of 4.2 million related to amending a previously filed tax return. We estimate that our annual effective income tax rate for the full year 2021 will be approximately 22.0 percent.
North America
Sales in the North America segment were $658 million in the third quarter of 2021, or $114 million higher than sales of $544 million in the third quarter of 2020. Sales in the first nine months of 2021 were $1,815 million or $258 million higher than sales of $1,557 million in the same period last year. The increases in sales in the third quarter and first nine months 2021 compared to the prior-year periods were primarily due to the impact of pricing actions, largely on water heaters, implemented to offset higher steel, other material and logistics costs, as well as higher water heater, boiler, and water treatment volumes.
North America segment earnings were $151.8 million in the third quarter of 2021, or approximately 14 percent higher than segment earnings of $133.1 million in the same period of 2020. Segment earnings in the first nine months of 2021 were $423.9 million, or approximately 16 percent higher than segment earnings of $365.6 million in the first nine months of 2020. Segment margin of 23.1 percent in the third quarter of 2021 was lower than segment margin of 24.5 percent in the same period last year. Segment margin of 23.4 percent in the first nine months of 2021 was slightly lower than segment margin of 23.5 percent in the same period last year. Adjusted segment earnings and adjusted segment margin in the third quarter of 2020 were $133.6 million and 24.6 percent, respectively. Adjusted segment earnings and adjusted segment margin in the first nine months of 2020 were $368.3 million and 23.6 percent, respectively. Higher segment earnings in the third quarter and first nine months of 2021 compared to the prior-year periods were primarily driven by inflation-related price increases implemented to offset higher costs as well as higher volumes, partially offset by higher material and freight costs. Segment earnings and margin in the prior-year periods were also adversely impacted by certain costs related to the pandemic. These costs included temporarily moving production from Mexico to the U.S., paying employees during temporary plant shutdowns, proactively deep cleaning facilities,
20

Table of Contents
paying benefits during employee furloughs, and other costs, which were approximately $1.1 million and $6.6 million for the three and nine months ended 2020, respectively. We expect 2021 full-year segment margin to be between 22.75 and 23.0 percent.
Adjusted segment earnings and adjusted segment margin in the third quarter and first nine months of 2020 exclude $0.5 million and $2.7 million, respectively, of pre-tax severance and restructuring expenses associated with an initiative to align our business to market conditions.
Rest of World
Sales in the Rest of World segment were $263 million in the third quarter of 2021, $42 million higher than sales of $221 million in the third quarter of 2020. Sales in the first nine months of 2021 were $749 million, $228 million higher than sales of $521 million in the first nine months of 2020. Sales in China increased approximately 19 percent in U.S. dollar terms and 12 percent in local currency in the third quarter of 2021 and increased approximately 46 percent in U.S. dollar terms and 36 percent in local currency in the first nine months of 2021 compared to the same periods last year. The increase in Rest of World sales in the third quarter and first nine months of 2021 was primarily due to sales growth in each of our major product lines in China compared to the same periods last year. In addition, sales in China benefited from currency translation of approximately $14 million and $49 million in the third quarter and first nine months of 2021, respectively, compared to the same periods last year, due to the appreciation of the Chinese currency compared to the U.S. dollar.
Rest of World segment earnings were $26.8 million in the third quarter of 2021, compared to earnings of $16.7 million in the third quarter of 2020. Segment earnings in the first nine months of 2021 were $60.9 million, compared to losses of $31.3 million in the first nine months of 2020. Segment margin was 10.2 percent and 8.1 percent in the third quarter and first nine months of 2021, compared to 7.5 percent in the third quarter of 2020 and negative margin in the first nine months of 2020. Adjusted segment earnings in the third quarter of 2020 were $17.8 million and adjusted segment losses were $26.3 million in the first nine months of 2020. Higher segment earnings and segment margin in the third quarter and first nine months of 2021 compared to the prior-year periods were primarily driven by higher volumes that were partially offset by higher employee incentive costs and brand building-related advertising costs in China compared to the same periods last year. In both periods in 2021, higher segment earnings and margins were partially offset by the absence of social insurance waivers, which we received in China in the prior-year periods. We expect full-year segment margin to be approximately eight percent in 2021.
Adjusted segment earnings in the third quarter and first nine months of 2020 exclude $1.1 million and $5.0 million, respectively, of pre-tax severance and restructuring expenses associated with an initiative to align our business to market conditions.
Outlook
Excluding the impact of our recent acquisition of Giant Factories, Inc. (Giant), we expect our consolidated sales to grow between 20 and 21 percent in 2021 on inflation-related pricing actions and strong China, North America water heater, water treatment and boiler volumes. Our sales growth projection includes approximately $54 million of benefit from China currency translation. We increased the midpoint of our EPS guidance for 2021 and we believe we will achieve full-year net earnings of between $2.86 and $2.90 per share. Our 2021 guidance excludes the potential impacts from future acquisitions.
Liquidity & Capital Resources
Working capital of $756 million as of September 30, 2021, was $24 million higher than at December 31, 2020. The change in working capital was driven by sales-related increases to accounts receivable balances and higher inventories that were partially offset by higher accounts payable balances. As of September 30, 2021, approximately $520 million of our $685 million of cash, cash equivalents, and marketable securities was held by our foreign subsidiaries. In the first nine months of 2021, we repatriated approximately $160 million of cash from our foreign subsidiaries. We used the proceeds to repurchase shares of our common stock.
Cash provided by operations in the first nine months of 2021 was $376.8 million compared with $330.4 million during the same period last year. The impact of higher earnings was partially offset by higher investments in working capital compared with the same period in 2020. For the full year 2021, we expect cash provided by operating activities will be between $550 and $575 million, similar to 2020 cash provided by operating activities of $562 million primarily due to higher earnings in 2021 being offset by higher investments in working capital compared to last year.
Capital expenditures totaled $45.3 million in the first nine months of 2021, compared with $36.7 million in the year-ago period. We project 2021 capital expenditures will be between $70 and $75 million, and full-year depreciation and amortization expense will be approximately $80 million.

During the second quarter of 2021, we renewed and amended our $500 million revolving credit facility, which now expires on April 1, 2026. The renewed and amended facility, with a group of nine banks, has an accordion provision that allows it to be increased up to $850 million if certain conditions (including lender approval) are satisfied. Borrowing rates under the facility are determined by our leverage ratio. The facility requires us to maintain two financial covenants, a leverage ratio test and an interest coverage test, and we were in compliance with the covenants as of September 30, 2021. We did not have borrowings on this facility as of September 30, 2021.
The facility backs up commercial paper and credit line borrowings. At September 30, 2021, we had an available borrowing capacity of $500 million under this facility. We believe the combination of available borrowing capacity and operating cash flows will provide sufficient funds to finance our existing operations for the foreseeable future.
Our total debt decreased by $6.8 million from $113.2 million at December 31, 2020 to $106.4 million at September 30, 2021. Our leverage, as measured by the ratio of total debt to total capitalization, calculated excluding operating lease liabilities, was 5.3 percent at September 30, 2021, compared with 5.8 percent at December 31, 2020.
Our pension plan continues to meet all funding requirements under ERISA regulations. We are not required to make a contribution and we do not plan to make any voluntary contributions to the plan in 2021.
In the first quarter of 2021, our Board of Directors approved adding 7,000,000 shares of common stock to our existing discretionary share repurchase authority. Under our share repurchase program, we may purchase our common stock through a combination of a Rule 10b5-1 automatic trading plan and discretionary purchases in accordance with applicable securities laws. The stock repurchase authorization remains effective until terminated by our Board of Directors, which may occur at any time, subject to the parameters of any Rule 10b5-1 automatic trading plan that we may then have in effect. During the first nine months of 2021, we repurchased 3,177,467 shares of our stock at a total cost of $212.0 million. As of September 30, 2021, we had 5,436,357 shares remaining on the share repurchase authority. After a black out period on share repurchase activity in the third quarter related to the Giant acquisition, we plan to resume our repurchase program in early November. Depending on factors such as stock price, working capital requirements and alternative investment opportunities, we expect to spend approximately $400 million on stock repurchases in 2021 through a combination of our Rule 10b5-1 automatic trading plan and opportunistic repurchases in the open market.
On October 11, 2021, our Board of Directors increased the rate of our quarterly cash dividend of $0.28 per share on our Common Stock and Class A common stock. The dividend is payable on November 15, 2021, to shareholders of record on October 29, 2021.
On October 19, 2021, we acquired Giant, a Canada-based manufacturer of residential and commercial water heaters for approximately $192 million using a combination of debt and cash. Giant manufactures water heaters at two facilities in Montreal, Canada and sells water heating products under the Giant brand across Canada. Giant had trailing twelve-month annual sales of approximately $105 million.

Non-GAAP Financial Information
We provide a non-GAAP measure, adjusted earnings per share (EPS) that excludes severance and restructuring expenses in 2020. We believe that this measure of adjusted EPS provides useful information to investors about our performance and allows management and our investors to better compare our performance period over period.

Critical Accounting Policies
Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the U.S., which requires the use of estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Future events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results inevitably will differ from those estimates, and such differences may be material to the financial statements. The critical accounting policies that we believe could have the most significant effect on our reported results or require complex judgment by management are contained in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the year ended December 31, 2020. We believe that at September 30, 2021, there has been no material change to this information.
Recent Accounting Pronouncement
Refer to Recent Accounting Pronouncement in Note 1 – Basis of Presentation in the notes to our condensed consolidated financial statements included in Part 1 Financial Information.
Forward Looking Statements
This filing contains statements that the Company believes are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally can be identified by the use of words such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “forecast,” “continue,” “guidance” or words of similar meaning. All forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those anticipated as of the date of this filing. Important factors that could cause actual results to differ materially from these expectations include, among other things, the following: the Company's ability to continue to obtain commodities, components, parts and accessories on a timely basis through its supply chain and at expected costs; negative impacts to the Company’s businesses, including demand for its products, particularly commercial products, operations and workforce dislocation and disruption as a result of the severity and duration of the COVID-19 pandemic; inability of the Company to implement or maintain pricing actions; an uneven recovery of the Chinese economy or decline in the growth rate of consumer spending or housing sales in China; negative impact to the Company’s businesses from international tariffs, trade disputes and geopolitical differences; potential weakening in the high-efficiency boiler segment in the U.S.; substantial defaults in payment, material reduction in purchases by or the loss, bankruptcy or insolvency of a major customer, including from the result of COVID-19; a weakening in U.S. residential or commercial construction or instability in the Company’s replacement markets; foreign currency fluctuations; the Company’s inability to successfully integrate or achieve its strategic objectives resulting from acquisitions; competitive pressures on the Company’s businesses; the impact of potential information technology or data security breaches; changes in government regulations or regulatory requirements; and adverse developments in general economic, political and business conditions in key regions of the world. Forward-looking statements included in this filing are made only as of the date of this filing, and the Company is under no obligation to update these statements to reflect subsequent events or circumstances. All subsequent written and oral forward-looking statements attributed to the Company, or persons acting on its behalf, are qualified entirely by these cautionary statements.
ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
As is more fully described in our Annual Report on Form 10-K for the year ended December 31, 2020, we are exposed to various types of market risks, including currency and certain commodity risks. Our quantitative and qualitative disclosures about market risk have not materially changed since that report was filed. We monitor our currency and commodity risks on a continuous basis and generally enter into forward and futures contracts to minimize these exposures. The majority of the contracts are for periods of less than one year. Our Company does not engage in speculation in our derivative strategies. It is important to note that gains and losses from our forward and futures contract activities are offset by changes in the underlying costs of the transactions being hedged.

ITEM 4 - CONTROLS AND PROCEDURES
Evaluation of disclosure controls and procedures
Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (Exchange Act). Based upon this evaluation of these disclosure controls and procedures, our principal executive officer and principal financial officer concluded that the disclosure controls and procedures were effective as of September 30, 2021 to ensure 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 period specified in the SEC rules and forms, and to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive and principal financial officers, as appropriate, to allow timely decisions regarding disclosure.
Changes in internal control over financial reporting
There have been no changes in our internal control over financial reporting during the quarter ended September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
PART II - OTHER INFORMATION
ITEM 1 - LEGAL PROCEEDINGS
There have been no material changes in the legal and environmental matters discussed in Part 1, Item 3 and Note 15 of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2020.
ITEM 1A RISK FACTORS
There have been no material changes from the risk factors disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, except for the addition of the risk factor set forth below:
Our operations could be adversely impacted by material and component price volatility and availability, as well as supplier concentration
The market prices for certain materials and components we purchase, primarily steel, have been volatile. U.S. steel index prices alone have increased 100 percent since the beginning of 2021. In addition, some components are subject to long lead times. Disruptions to the commercial transportation network, including limited container and trucking capacity and port congestion, have increased supplier delivery times for materials and components to our facilities and, in some cases, our ability to timely ship to customers. We engage in ongoing communications with our suppliers to identify and mitigate risk of potential disruptions and to manage our material and component inventory levels. Significant increases in the cost of any of the key materials and components we purchase or delays in their delivery could increase our cost of doing business and ultimately could lead to lower operating earnings if we are not able to recover these cost increases through price increases to our customers. As a response to cost inflation in materials and components, we have announced five price increases on water heaters in North America that compound to approximately 50 percent in 2021. Historically, there has been a lag in our ability to recover increased material costs from customers, and that lag, particularly for the price increases implemented in 2021, could negatively impact our profitability. In some cases, we are dependent on a limited number of suppliers for some of the raw materials and components we require in the manufacturing of our products. A significant disruption or termination of the supply from one of these suppliers could delay sales or increase costs which could result in a material adverse effect on our financial condition, results of operations and cash flows.

ITEM 2 - UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
In the first quarter of 2021, our Board of Directors approved adding 7,000,000 shares of common stock to the existing discretionary share repurchase authority. Under the share repurchase program, the Common Stock may be purchased through a combination of Rule 10b5-1 automatic trading plan and discretionary purchases in accordance with applicable securities laws. The number of shares purchased and the timing of the purchases will depend on a number of factors, including share price, trading volume and general market conditions, as well as working capital requirements, general business conditions and other factors, including alternative investment opportunities. The stock repurchase authorization remains effective until terminated by our Board of Directors which may occur at any time, subject to the parameters of any Rule 10b5-1 automatic trading plan that we may then have in effect. In the third quarter of 2021, we repurchased 198,810 shares at an average price of $69.48 per share and at a total cost of $13.8 million. As of September 30, 2021, there were 5,436,357 shares remaining on the existing repurchase authorization.
