Item 8. Financial Statements and Supplementary Data

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. As defined by the Securities and Exchange Commission, internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements in accordance with U.S. generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management, including our Chief Executive Officer and Chief Financial Officer, has undertaken an assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) by the Committee of Sponsoring Organizations of the Treadway Commission. Management's assessment included an evaluation of the design of the Company's internal control over financial reporting and testing of the operational effectiveness of those controls.

Based on this assessment, management concluded that as of December 31, 2017, the Company's internal control over financial reporting was effective.

KPMG LLP, the independent registered public accounting firm that audited the Company's consolidated financial statements, has issued an audit report including an opinion on the effectiveness of our internal control over financial reporting as of December 31, 2017, a copy of which is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors

Lennox International Inc.:

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of Lennox International Inc. and subsidiaries (the Company) as of December 31, 2017 and 2016, the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2017, and the related notes and Schedule II - Valuation and Qualifying Accounts and Reserves (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, in 2017 the Company adopted Accounting Standards Update No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which requires entities to record all tax effects related to share-based payments at settlement or expiration through the income statement.

Basis for Opinion

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable

assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

LENNOX INTERNATIONAL INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of Operations:

Lennox International Inc., a Delaware corporation, through its subsidiaries (referred to herein as "we," "our," "us," "LII," or the "Company"), is a leading global provider of climate control solutions. We design, manufacture, market and service a broad range of products for the heating, ventilation, air conditioning and refrigeration ("HVACR") markets and sell our products and services through a combination of direct sales, distributors and company-owned parts and supplies stores. We operate in three reportable business segments: Residential Heating & Cooling, Commercial Heating & Cooling, and Refrigeration. See Note 18 for financial information regarding our reportable segments.

2. Summary of Significant Accounting Policies:

Principles of Consolidation

The consolidated financial statements include the accounts of Lennox International Inc. and our majority-owned subsidiaries. All intercompany transactions, profits and balances have been eliminated.

Cash and Cash Equivalents

We consider all highly liquid temporary investments with original maturity dates of three months or less to be cash equivalents. Cash and cash equivalents consisted primarily of bank deposits.

Accounts and Notes Receivable

Accounts and notes receivable are shown in the accompanying Consolidated Balance Sheets, net of allowance for doubtful accounts. The allowance for doubtful accounts is generally established during the period in which receivables are recognized and is based on the age of the receivables and management's judgment on our ability to collect. Management considers the historical trends of write-offs and recoveries of previously written-off accounts, the financial strength of customers and projected economic and market conditions. We determine the delinquency status of receivables predominantly based on contractual terms and we write-off uncollectible receivables after management's review of our ability to collect, as noted above. We have no significant concentrations of credit risk within our accounts and notes receivable.

Inventories

Inventory costs include material, labor, depreciation and plant overhead. Inventories of $274.5 million and $221.4 million as of December 31, 2017 and 2016, respectively, were valued at the lower of cost or market using the last-in, first-out (“LIFO”) cost method. The remainder of inventory is valued at the lower of cost or market with cost determined primarily using either the first-in, first-out (“FIFO”) or average cost methods.

We elected to use the LIFO cost method for our domestic manufacturing companies in 1974 and continued to elect the LIFO cost method for new operations through the late 1980s. The types of inventory costs that use LIFO include raw materials, purchased components, work-in-process, repair parts and finished goods. Since the late 1990s, we have adopted the FIFO cost method for all new domestic manufacturing operations (primarily acquisitions). Our operating entities with a previous LIFO election continue to use the LIFO cost method. We use the FIFO cost method for our foreign-based manufacturing facilities. See Note 3 for more information on our inventories.

Property, Plant and Equipment

Property, plant and equipment is stated at cost, net of accumulated depreciation. Expenditures that increase the utility or extend the useful lives of fixed assets are capitalized while expenditures for maintenance and repairs are charged to expense as incurred.

Depreciation is computed using the straight-line method over the following estimated useful lives:

Buildings and improvements:
Buildings and improvements	2 to 33 years
Leasehold improvements	1 to 39 years
Machinery and equipment:
Computer hardware	3 to 5 years
Computer software	3 to 10 years
Factory machinery and equipment	1 to 15 years
Research and development equipment	3 to 10 years
Vehicles	2 to 8 years

We periodically review long-lived assets for impairment as events or changes in circumstances indicate that the carrying amount of such assets might not be recoverable. To assess recoverability, we compare the estimated expected future undiscounted cash flows identified with each long-lived asset or related asset group to the carrying amount of such assets. If the expected future cash flows do not exceed the carrying value of the asset or assets being reviewed, an impairment loss is recognized based on the excess of the carrying amount of the impaired assets over their fair value. See Note 5 for additional information on our property, plant and equipment.

Goodwill

Goodwill represents the excess of cost over fair value of assets from acquired businesses. Goodwill is not amortized, but is reviewed for impairment annually and whenever events or changes in circumstances indicate the asset may be impaired (See Note 4 for additional information on our goodwill). The annual goodwill impairment test was performed during the fourth quarter of 2017.

The provisions of the accounting standard for goodwill allow us to first assess qualitative factors to determine whether it is necessary to perform a two-step quantitative goodwill impairment test. As part of our qualitative assessment, we monitor economic, legal, regulatory and other factors, industry trends, our market capitalization, recent and forecasted financial performance of our reporting units and the timing and nature of our restructuring activities for LII as a whole and for each reporting unit.

If a quantitative goodwill impairment test is determined to be necessary, we estimate reporting unit fair values using a combination of the discounted cash flow approach and a market approach. The discounted cash flows used to estimate fair value are based on assumptions regarding each reporting unit’s estimated projected future cash flows and the estimated weighted-average cost of capital that a market participant would use in evaluating the reporting unit in a purchase transaction. The estimated weighted-average cost of capital is based on the risk-free interest rate and other factors such as equity risk premiums and the ratio of total debt to equity capital. In performing these impairment tests, we take steps to ensure that appropriate and reasonable cash flow projections and assumptions are used. We reconcile our estimated enterprise value to our market capitalization and determine the reasonableness of the cost of capital used by comparing to market data. We also perform sensitivity analyses on the key assumptions used, such as the weighted-average cost of capital and terminal growth rates. The market approach is based on objective evidence of market values.

Intangible Assets

We amortize intangible assets and other assets with finite lives over their respective estimated useful lives to their estimated residual values, as follows:

Asset	Useful Life
Deferred financing costs	Effective interest method
Customer relationships	Straight-line method up to 12 years
Patents and others	Straight-line method up to 20 years

We periodically review intangible assets with estimable useful lives for impairment as events or changes in circumstances indicate that the carrying amount of such assets might not be recoverable. We assess recoverability by comparing the estimated expected undiscounted future cash flows identified with each intangible asset or related asset group to the carrying amount of such assets. If the expected future cash flows do not exceed the carrying value of the asset or assets being reviewed, an impairment

loss is recognized based on the excess of the carrying amount of the impaired assets over their fair value. In assessing the fair value of these intangible assets, we must make assumptions that a market participant would make regarding estimated future cash flows and other factors to determine the fair value of the respective assets. If these estimates or the related assumptions change, we may be required to record impairment charges for these assets in the future.

We review our indefinite-lived intangible assets for impairment annually in the fourth quarter and whenever events or changes in circumstances indicate the asset may be impaired. The provisions of the accounting standard for indefinite-lived intangible assets allow us to first assess qualitative factors to determine whether it is necessary to perform a two-step quantitative impairment test. As part of our qualitative assessment, we monitor economic, legal, regulatory and other factors, industry trends, recent and forecasted financial performance of our reporting units and the timing and nature of our restructuring activities for LII as a whole and as they relate to the fair value of the assets. See Note 4 for additional information on our intangible assets.

Product Warranties

For some of our heating, ventilation and air conditioning (“HVAC”) products, we provide warranty terms ranging from one to 20 years to customers for certain components such as compressors or heat exchangers. For select products, we also provide limited lifetime warranties. A liability for estimated warranty expense is recorded on the date that revenue is recognized. Our estimates of future warranty costs are determined by product line. The number of units we expect to repair or replace is determined by applying an estimated failure rate, which is generally based on historical experience, to the number of units that were sold and are still under warranty. The estimated units to be repaired under warranty are multiplied by the average cost to repair or replace such products to determine the estimated future warranty cost. We do not discount product warranty liabilities as the amounts are not fixed and the timing of future cash payments is neither fixed nor reliably determinable. We also provide for specifically-identified warranty obligations. Estimated future warranty costs are subject to adjustment depending on changes in actual failure rate and cost experience. Subsequent costs incurred for warranty claims serve to reduce the accrued product warranty liability. See Note 10 for more information on our estimated future warranty costs.

Pensions and Post-retirement Benefits

We provide pension and post-retirement medical benefits to eligible domestic and foreign employees and we recognize pension and post-retirement benefit costs over the estimated service life or average life expectancy of those employees. We also recognize the funded status of our benefit plans, as measured at year-end by the difference between plan assets at fair value and the benefit obligation, in the Consolidated Balance Sheets. Changes in the funded status are recognized in the year in which the changes occur through accumulated other comprehensive income (“AOCI”). Actuarial gains or losses are amortized into net period benefit cost over the estimated service life of covered employees or average life expectancy of participants depending on the plan.

The benefit plan assets and liabilities reflect assumptions about the long-range performance of our benefit plans. Should actual results differ from management's estimates, revisions to the benefit plan assets and liabilities would be required. See Note 12 for information regarding those estimates and additional disclosures on pension and post-retirement medical benefits.

Self-Insurance

Self-insurance expense and liabilities were actuarially determined based primarily on our historical claims information and industry factors and trends. The self-insurance liabilities as of December 31, 2017 represent the best estimate of the future payments to be made on reported and unreported losses for 2017 and prior years. The amounts and timing of payments for claims reserved may vary depending on various factors, including the development and ultimate settlement of reported and unreported claims. To the extent actuarial assumptions change and claims experience rates differ from historical rates, our liabilities may change. See Note 10 for additional information on our self-insured risks and liabilities.

Derivatives

We use futures contracts, forward contracts and fixed forward contracts to mitigate our exposure to volatility in metal commodity prices and foreign exchange rates. We hedge only exposures in the ordinary course of business and do not hold or trade derivatives for profit. All derivatives are recognized in the Consolidated Balance Sheets at fair value and the classification of each derivative instrument is based upon whether the maturity of the instrument is less than or greater than 12 months. See Note 8 for more information on our derivatives.

Income Taxes

We recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial

statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Unrecognized tax benefits are accounted for as required by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 740. See Note 9 for more information related to income taxes.

Revenue Recognition

Our revenue recognition practices for the sale of goods depend upon the shipping terms for each transaction. Shipping terms are primarily FOB Shipping Point and, therefore, revenue is recognized for these transactions when products are shipped to customers and title passes. Certain customers in our smaller operations, primarily outside of North America, have shipping terms where title and risk of ownership do not transfer until the product is delivered to the customer. For these transactions, revenue is recognized on the date that the product is received and accepted by such customers. We experience returns for miscellaneous reasons and record a reserve for these returns at the time we recognize revenue based on historical experience. Our historical rates of return are insignificant as a percentage of sales. We also recognize revenue net of sales taxes.

For our businesses that provide services, revenue is recognized at the time services are completed. Our Commercial Heating & Cooling segment also provides sales, installation, maintenance and repair services under fixed-price contracts. Revenue for equipment sales is recognized in line with shipping terms, revenue for installation services is recognized when completed, and revenue related to maintenance and repair services is recognized when such services are performed.

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. See Note 22 for more information on these costs.

Cost of Goods Sold

The principal elements of cost of goods sold are components, raw materials, factory overhead, labor, estimated costs of warranty expense and freight and distribution costs.

Selling, General and Administrative Expenses

SG&A expenses include payroll and benefit costs, advertising, commissions, research and development, information technology costs, and other selling, general and administrative related costs such as insurance, travel, non-production depreciation and rent.

Stock-Based Compensation

We recognize compensation expense for stock-based arrangements over the required employee service periods. We measure stock-based compensation costs on the estimated grant-date fair value of the stock-based awards that are expected to ultimately vest and we adjust expected vesting rates to actual rates as additional information becomes known. For stock-based arrangements with performance conditions, we periodically adjust performance achievement rates based on our best estimates of those rates at the end of the performance period. See Note 14 for more information.

Translation of Foreign Currencies

All assets and liabilities of foreign subsidiaries and joint ventures are translated into U.S. dollars using rates of exchange in effect at the balance sheet date. Revenue and expenses are translated at weighted average exchange rates during the year. Unrealized translation gains and losses are included in AOCI in the accompanying Consolidated Balance Sheets. Transaction gains and losses are included in Losses and other expenses, net in the accompanying Consolidated Statements of Operations.

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 revenue and expenses. Such estimates include the valuation of accounts receivable, inventories,

goodwill, intangible assets and other long-lived assets, contingencies, product warranties, guarantee obligations, indemnifications, and assumptions used in the calculation of income taxes, pension and post-retirement medical benefits, 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 and uncertain future economic conditions 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 resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Reclassifications

Certain amounts have been reclassified from the prior year presentation to conform to the current year presentation.

Recently Adopted Accounting Guidance

On March 30, 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which changes the accounting for certain aspects of share-based payments to employees. The new guidance requires entities to record all tax effects related to share-based payments at settlement or expiration through the income statement and the excess tax benefit to be recorded when it arises, subject to normal valuation allowance considerations. This is in comparison to the prior requirement that these excess tax benefits be recognized in additional paid-in capital. The new guidance also requires excess tax benefits to be classified along with other income tax cash flows as an operating activity in the statement of cash flows rather than, as previously required, a financing activity.

We have adopted ASU 2016-09 effective January 1, 2017 on a prospective basis where permitted by the new standard. As a result of this adoption:

•	We recognized discrete tax benefits of $23.6 million in the income taxes line item of our consolidated statements of operations for the twelve months ended December 31, 2017 related to excess tax benefits upon vesting or settlement in that period.

•	We elected to adopt the cash flow presentation of the excess tax benefits retrospectively where these benefits are classified along with other income tax cash flows as operating cash flows.

•	We have elected to continue to estimate the number of stock-based awards expected to vest, rather than electing to account for forfeitures as they occur to determine the amount of compensation cost to be recognized in each period.

•	We excluded the excess tax benefits from the assumed proceeds available to repurchase shares in the computation of our diluted earnings per share for the year ended December 31, 2017.

Recent Accounting Pronouncements

On May 28, 2014, the Financial Accounting Standard Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for us on January 1, 2018. Early application is not permitted. We have substantially completed our evaluation of the effect that ASU 2014-09 will have on our Consolidated Financial Statements and related disclosures. The ASU will not have a material impact on the amount and timing of revenue recognition, but it will require us to enhance our disclosures to provide additional information relating to disaggregated revenue, contract assets and liabilities, and remaining performance obligations. We are currently in the process of preparing these additional disclosures, including updating our internal controls related to the additional data and disclosures to be provided upon adoption of the new standard. We will adopt the new standard using the modified retrospective approach.

On February 25, 2016, the FASB issued ASU No. 2016-02, Leases (ASC 842). Lessees will need to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability. It will be critical to identify leases embedded in a contract to avoid misstating the lessee’s balance sheet. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting, but without explicit bright lines. ASU 2016-02 is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years. We will adopt the standard using the prospective approach and are still determining the effect of the standard on our ongoing financial reporting. As a result of the new standard,

all of our leases greater than one year in duration will be recognized on our Consolidated Balance Sheets as both operating lease liabilities and right-of-use assets upon adoption of the standard.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. The amendments in this ASU clarify the classification for eight different types of activities, including debt prepayment and extinguishment costs, proceeds from insurance claims and distributions from equity method investees. For public business entities, the standard is effective for financial statements issued for fiscal years beginning after December 15, 2017. This standard is not expected to have a material impact on our consolidated financial statements.

On October 24, 2016, the FASB issued ASU 2016-16, Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory. The new ASU eliminates the existing exception from recognition of the tax consequences of intercompany sales of assets other than inventory. Under the new standard, when an asset (other than inventory) is sold from one consolidated entity to another, the tax consequences to the seller will be recognized currently as a component of the current tax provision. The new guidance will be effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those years. In accordance with the ASU, our previously deferred tax costs and unrecognized deferred tax assets related to intra-entity asset transfers will need to be recognized at the date of transition through a cumulative effect adjustment to opening retained earnings upon adoption of the standard.

On March 10, 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. ASU 2017-07 changes the income statement presentation of defined benefit plan expense by requiring separation between operating expense (service cost component) and non-operating expense (all other components, including interest cost, amortization of prior service cost, curtailments and settlements, etc.). The operating expense component is reported with similar compensation costs while the non-operating components are reported in Other Income, net. In addition, only the service cost component is eligible for capitalization as part of an asset such as inventory or property, plant and equipment. The ASU will not have a material impact on our financial results.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12 intends to better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The guidance in ASU 2017-12 is required for annual reporting periods beginning after December 15, 2018, with early adoption permitted. We intend to adopt this guidance in 2018 as it will allow us to designate certain aluminum commodity futures contracts as cash flow hedges.

3. Inventories:

The components of inventories are as follows (in millions):

	As of December 31,
	2017				2016
Finished goods	$	331.9			$	287.2
Work in process	5.5				5.1
Raw materials and parts	199.2				183.4
Total	536.6				475.7
Excess of current cost over last-in, first-out cost	(52.4		)		(57.2		)
Total inventories, net	$	484.2			$	418.5

The Company recorded no pre-tax loss in 2017, pre-tax loss of $0.2 million in 2016 and pre-tax loss of $0.2 million in 2015 from LIFO inventory liquidations. Reserve balances, primarily related to obsolete and slow-moving inventories, were $20.1 million and $19.7 million at December 31, 2017 and December 31, 2016, respectively.

4. Goodwill and Intangible Assets:

Goodwill

The changes in the carrying amount of goodwill in 2017 and 2016, in total and by segment, are summarized in the table below (in millions):

Segment:	Balance at December 31, 2015 (1)				Change in foreign currency translation rate				Balance at December 31, 2016				Change in foreign currency translation rate				Balance at December 31, 2017
Residential Heating & Cooling	$	26.1			$	—			$	26.1			$	—			$	26.1
Commercial Heating & Cooling	60.6				(0.5		)		60.1				2.1				62.2
Refrigeration	108.4				0.5				108.9				3.3				112.2
	$	195.1			$	—			$	195.1			$	5.4			$	200.5

(1) The goodwill balances in the table above are presented net of accumulated impairment charges of $21.2 million, all of which relate to impairments in periods prior to 2016.

We reviewed our reporting unit structure as part of our annual goodwill impairment testing. We identified several components one level below our operating segments which were determined to be reporting units. We then performed our analysis to determine the proper aggregation of our reporting units, which considered similar economic and other characteristics, including product types, gross profits, production processes, customer types, distribution processes, and regulatory environments. Our analysis incorporated qualitative and quantitative measures to evaluate economic similarity and concluded that our reporting units continue to be equivalent to our operating segments except that we began evaluating our North America supermarket display cases and systems business separately beginning in 2015.

A qualitative review of impairment indicators was performed in 2017 for the Residential Heating & Cooling, the Commercial Heating & Cooling, and the Refrigeration segments and we determined that it was not more likely than not that the fair values of our reporting units, individually or collectively, were less than their carrying values. Accordingly, a quantitative impairment analysis was not performed for these segments. No indicators of goodwill impairment were identified during the current year. Also, we did not record any goodwill impairments related to continuing operations in 2016. During the fourth quarter of 2015 we performed a quantitative impairment analysis of our North American supermarket display cases and systems business. Based on the results of the quantitative impairment test, we recorded impairment of $5.5 million in "Goodwill impairment" in the Consolidated Statement of Operations.

Intangible Assets

As of December 31, 2017 and 2016, there were $4.3 million and $4.3 million, respectively, of indefinite-lived intangible assets recorded in Other assets, net in the accompanying Consolidated Balance Sheets. These intangible assets consisted primarily of trademarks and are not subject to amortization.

Identifiable intangible and other assets subject to amortization were recorded in Other assets, net in the accompanying Consolidated Balance Sheets and were comprised of the following (in millions):

	As of December 31,
	2017												2016
	Gross Amount				Accumulated Amortization				Net Amount				Gross Amount				Accumulated Amortization				Net Amount
Customer relationships	15.8				(15.1		)		0.7				15.9				(14.9		)		1.0
Patents and others	14.3				(6.4		)		7.9				12.7				(6.4		)		6.3
Total	$	30.1			$	(21.5	)		$	8.6			$	28.6			$	(21.3	)		$	7.3

Amortization expense related to these intangible and other assets was as follows (in millions):

	For the Years Ended December 31,
	2017				2016				2015
Amortization expense (1)	$	0.5			$	0.4			$	2.7

(1) Included in the amortization expense in 2015 are amounts relating to customer relationships that were written off during the fourth quarter of 2015.

Estimated amortization expense for the next five years and thereafter is as follows (in millions):

Estimated Future Amortization Expense:
2018	$	0.5
2019	0.5
2020	0.4
2021	0.2
2022	0.2
Thereafter	6.8

During the fourth quarter of 2015, we completed a strategic review of our North American supermarket display cases and systems business. As a result, we performed an impairment analysis using a market approach and determined that intangible assets relating to the North American supermarket display case business trade name and its customer relationships were impaired and we recorded a charge of $21.2 million in "Asset impairment" in the Consolidated Statement of Operations. We did not have any impairments of intangible assets related to continuing operations in 2017 or 2016.

5. Property, Plant and Equipment:

Components of Property, plant and equipment, net were as follows (in millions):

	As of December 31,
	2017				2016

Less accumulated depreciation	(774.2		)		(717.2		)
Property, plant and equipment, net	$	397.8			$	361.4

During the fourth quarter of 2015, we completed a strategic review of our North American supermarket display cases and systems business. As a result, we performed an impairment analysis using a market approach and determined that property, plant and equipment relating to the North American supermarket display case business unit were impaired and we recorded a charge of $23.3 million in "Asset impairment" in the Consolidated Statement of Operations. No impairment charges were recorded in 2017 or 2016.

6. Joint Ventures and Other Equity Investments:

We participate in two joint ventures, the largest located in the U.S. and the other in Mexico, 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 respective 25% and 50% ownerships, 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.

The combined balance of equity method investments included in Other assets, net totaled (in millions):

	As of December 31,
	2017				2016
Equity method investments	$	33.3			$	30.7

We purchase compressors from our U.S. joint venture for use in certain of our products. The amounts of purchases included in Cost of goods sold in the Consolidated Statements of Operations were as follows (in millions):

	For the Years Ended December 31,
	2017				2016				2015
Purchases of compressors from joint venture	$	106.4			$	97.7			$	103.5

8. 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 with lower percentages 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 interest 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 commodity futures contracts and foreign exchange forward contracts designated as cash flows hedges that are scheduled to mature through May 2019 and December 2018, respectively. Unrealized gains or losses from our cash flow hedges are included

in AOCI and are expected to be reclassified into earnings within the next 18 months based on the prices of the commodities at the settlement dates.

We recorded the following amounts related to our cash flow hedges in AOCI (in millions):

	As of December 31,
	2017				2016
Unrealized gains on unsettled contracts	$	(11.3	)		$	(8.9	)
Income tax expense	3.9				3.3
Gains included in AOCI, net of tax (1)	$	(7.4	)		$	(5.6	)

(1) Assuming commodity and foreign currency prices remain constant, we expect to reclassify $7.1 million of derivative gains into earnings within the next 12 months.

We had the following outstanding commodity futures contracts designated as cash flow hedges (in millions of pounds):

	As of December 31,
Notional Amounts	2017			2016

We had the following outstanding foreign exchange forward contracts designated as cash flow hedges (in millions):

	As of December 31,
Notional Amounts (in local currency):	2017			2016
Mexican Peso	207.3			310.1
Canadian Dollar	68.6			24.9

Derivatives not Designated as Cash Flow Hedges

For commodity derivatives not designated as cash flow hedges, we follow the same hedging strategy as derivatives designated as cash flow hedges, except that we elect not to designate them as cash flow hedges at the inception of the arrangement. We had

the following outstanding commodity futures contracts not designated as cash flow hedges (in millions of pounds):

	As of December 31,
	2017			2016

9. Income Taxes:

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate tax rate from 35 percent to 21 percent; (2) requiring companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries; (3) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations; (5) repeal of the domestic production activity deduction; and (6) limitations on the deductibility of certain executive compensation.

The SEC staff issued Staff Accounting Bulletin No. 118 ("SAB 118"), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

Our accounting for the following elements of the Tax Act is incomplete. However, we were able to make reasonable estimates of certain effects and, therefore, recorded provisional adjustments as follows:

•

The Tax Act reduced the corporate tax rate to 21 percent, effective January 1, 2018. For our net federal deferred tax assets ("DTA"), we have recorded a provisional decrease of $32.1 million, with a corresponding net adjustment to deferred income tax expense of $32.1 million for the year ended December 31, 2017. This adjustment is based on a reasonable estimate of the impact of the reduction in the corporate tax rate on our DTA's as of December 22, 2017. While we are able to make a reasonable estimate of the impact of the reduction in the corporate tax rate, our DTA's may be affected by other analyses related to the Tax Act, including our calculation of deemed repatriation of deferred foreign income and the state tax effect of adjustments made to federal temporary differences.

•

The Deemed Repatriation Transition Tax (Transition Tax) is a tax on previously untaxed accumulated and current earnings and profits (E&P) of certain of our foreign subsidiaries. To assess the amount of the Transition Tax, we must determine, in addition to other factors, the amount of post-1986 E&P of the relevant subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. We are able to make a reasonable estimate of the Transition Tax and currently estimate that we will not have a Transition Tax obligation. However, we are continuing to review additional information regarding our accumulated E&P and non-U.S. income taxes paid to more precisely compute the amount of the Transition Tax, if any. In addition, based on current state tax law, we estimate the state impact of the Transition Tax to be insignificant. This estimate will be revised based on a calculation of our final Transition Tax as well as any updated guidance on state treatment of the deemed repatriation.

•

We must assess whether our valuation allowance analyses are affected by various aspects of the Tax Act (e.g., deemed repatriation of deferred foreign income, global intangible low-taxed income ("GILTI") inclusions, new categories of foreign tax credits ("FTCs"), and share-based compensation). Since, as discussed herein, we have recorded provisional amounts related to certain portions of the Tax Act, any corresponding determination of the need for or change in a valuation allowance is also provisional. Due to the limitation on the utilization of future foreign tax credits, we recorded a provisional valuation allowance against our FTC carryforwards of $4.3 million. While we believe this is a reasonable estimate, the realizability of deferred tax assets related to share-based compensation may also be impacted by the Tax Act.

•

While we have not yet completed all of the computations necessary or completed a detailed inventory of our 2017 expenditures that qualify for immediate expensing, we have recorded a provisional benefit of $4.1 million based on our current intent to fully expense all qualifying expenditures. This resulted in a decrease of approximately $1.4 million to our current income tax payable and a corresponding increase in our deferred tax liabilities ("DTLs") of approximately $0.9 million (after considering the effects of the reduction in income tax rates). This provisional benefit will be refined as we complete the detailed analysis of qualifying expenditures.

Because of the complexity of the new GILTI tax rules, we are continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, we are allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). Our selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine whether we expect to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. We are not currently able to reasonably estimate the effect of the new GILTI tax rules on future U.S. inclusions in taxable income as the expected future impact of this provision of the Tax Act depends on our current structure and business. Therefore, we have not made any adjustments related to potential GILTI tax in our financial statements and have not made a policy decision regarding whether to record deferred taxes on GILTI.

The effect of the tax rate change for items originally recognized in other comprehensive income was properly recorded in tax expense from continuing operations. This results in stranded tax effects in accumulated other comprehensive income at December

31, 2017. Companies can make a policy election to reclassify from accumulated other comprehensive income to retained earnings the stranded tax effects directly arising from the change in the federal corporate tax rate. We will determine whether or not to make such a policy election in fiscal 2018.

Deferred income taxes reflect the tax consequences on future years of temporary differences between the tax basis of assets and liabilities and their financial reporting basis and depending on the classification of the asset or liability generating the deferred tax. The deferred tax provision for the periods shown represents the effect of changes in the amounts of temporary differences during those periods.

Deferred tax assets (liabilities) were comprised of the following (in millions):

	As of December 31,
	2017				2016
Gross deferred tax assets:
Warranties	$	27.3			$	36.3
Loss carryforwards (foreign, U.S. and state)	21.0				19.8
Post-retirement and pension benefits	23.3				33.9
Inventory reserves	7.5				9.6
Receivables allowance	3.5				4.5
Compensation liabilities	11.1				20.6
Deferred income	0.7				1.5
Insurance liabilities	5.1				6.5
Legal reserves	7.6				12.0
Tax credits, net of federal effect	21.3				18.4
Other	7.5				5.4
Total deferred tax assets	135.9				168.5
Valuation allowance	(24.9		)		(17.1		)
Total deferred tax assets, net of valuation allowance	111.0				151.4
Gross deferred tax liabilities:
Depreciation	(5.9		)		(3.3		)
Hedges	(3.6		)		(3.2		)
Intangibles	(4.9		)		(4.9		)
Other	(2.2		)		(3.3		)
Total deferred tax liabilities	(16.6		)		(14.7		)
Net deferred tax assets	$	94.4			$	136.7

As of December 31, 2017 and 2016, we had $0.8 million and $ 1.6 million in tax-effected state net operating loss carryforwards, respectively, and $19.8 million and $16.8 million in tax-effected foreign net operating loss carryforwards, respectively. The state and foreign net operating loss carryforwards began expiring in 2014. The deferred tax asset valuation allowance relates primarily to the operating loss carryforwards European and Asian tax jurisdictions. The remainder of the valuation allowance relates to state tax credits.

In assessing whether a deferred tax asset will be realized, we consider whether it is more likely than not that some portion or all of the deferred tax asset will not be realized. We consider the reversal of existing taxable temporary differences, projected future taxable income and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, we believe it is more likely than not we will realize the benefits of these deductible differences, net of the existing valuation allowances, as of December 31, 2017. To realize the net foreign deferred tax asset, we will need to generate future foreign taxable income of approximately $71.3 million during the periods in which those temporary differences become deductible.

As of December 31, 2017, we had foreign tax credit carryforwards in U.S. of $10.6 million. Due to the Tax Act, we no longer believe we will realize the full benefit of these credits due to the new limitation of utilizing foreign tax credits to reduce U.S. income tax. Therefore, we recorded a valuation allowance of $4.3 million.

No provision was made for income taxes which may become payable upon distribution of our foreign subsidiaries' earnings. These earnings were approximately $87.0 million as of December 31, 2017. An actual repatriation in the future from our non-U.S. subsidiaries could still be subject to foreign withholding taxes and U.S. state taxes.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in millions):

Balance as of December 31, 2015	$	0.5
Increases related to prior year tax positions	1.0
Increases related to current year tax positions	1.4
Settlement	(0.5		)
Balance as of December 31, 2016	2.4
Increases related to prior year tax positions	0.1
Decreases related to prior year tax positions	(2.5		)
Balance as of December 31, 2017	$	—

As of December 31, 2017, we no longer had any unrecognized tax benefits.

We are currently under examination for our U.S. federal income taxes for 2017 and 2016 and are subject to examination by numerous other taxing authorities in the U.S. and in jurisdictions such as France, Canada, India and Germany. We are generally no longer subject to U.S., state and local or non-U.S. income tax examinations by taxing authorities for years before 2011.

10. Commitments and Contingencies:

Leases

We lease certain real and personal property under non-cancelable operating leases. 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. We amortize this expense over the term of the lease beginning with the date of initial possession, which is the date we enter the leased space and begin to make improvements in preparation for its intended use.

Future annual minimum lease payments and capital lease commitments as of December 31, 2017 were as follows (in millions):

	Operating Leases				Capital Leases
2018	$	55.3			$	3.5
2019	42.4				0.6
2020	28.4				0.4
2021	18.3				0.1
2022	17.7				—
Thereafter	13.8				12.0
Total minimum lease payments	$	175.9			$	16.6
Less amount representing interest					0.2
Present value of minimum payments					$	16.4

On March 22, 2013, we entered into an agreement with a financial institution to renew the lease of our corporate headquarters in Richardson, Texas for a term of approximately six years through March 1, 2019 (the “Lake Park Renewal”). The leased property consists of an office building of approximately 192,000 square feet, land and related improvements. During the lease term, the Lake Park Renewal requires us to pay base rent in quarterly installments, payable in arrears. At the end of the lease term, we must

do one of the following: (i) purchase the property for $41.2 million; (ii) vacate the property and return it in good condition; (iii) arrange for the sale of the leased property to a third party; or (iv) renew the lease under mutually agreeable terms. If we elect to sell the property to a third party and the sales proceeds are less than the lease balance, we must pay any such deficit to the financial institution. Any such deficit payment cannot exceed 86% of the lease balance. The Lake Park Renewal is classified as an operating lease and its future annual minimum lease payments are included in the table above.

Our obligations under the Lake Park Renewal are secured by a pledge of our interest in the leased property. The Lake Park Renewal contains customary lease covenants and events of default as well as events of default if (i) indebtedness of $75 million or more is not paid when due, (ii) there is a change of control or (iii) we fail to comply with certain covenants incorporated from our Sixth Amended and Restated Credit Facility Agreement. We believe we were in compliance with these financial covenants as of December 31, 2017.

Environmental

Environmental laws and regulations in the locations we operate can potentially impose obligations to remediate hazardous substances at our properties, properties formerly owned or operated by us, and facilities to which we have sent or send waste for treatment or disposal. We are aware of contamination at some facilities; however, we do not believe that any future remediation related to those facilities will be material to our results of operations. Total environmental accruals are included in the following captions on the accompanying Consolidated Balance Sheets (in millions):

	As of December 31,
	2017				2016
Accrued expenses	$	3.5			$	1.2
Other liabilities	3.1				4.4
Total environmental accruals	$	6.6			$	5.6

Future environmental costs are estimates and may be subject to change due to changes in environmental remediation regulations, technology or site-specific requirements.

Product Warranties and Product Related Contingencies

We incur the risk of liability for claims related to the installation and service of heating and air conditioning products, and we maintain liabilities for those claims that we self-insure. We are involved in various claims and lawsuits related to our products. Our product liability insurance policies have limits that, if exceeded, may result in substantial costs that could have an adverse effect on our results of operations. In addition, warranty claims and certain product liability claims are not covered by our product liability insurance.

Total product warranty liabilities related to continuing operations are included in the following captions on the accompanying Consolidated Balance Sheets (in millions):

	As of December 31,
	2017				2016
Accrued expenses	$	34.8			$	30.0
Other liabilities	75.1				71.1
Total product warranty liabilities	$	109.9			$	101.1

The changes in product warranty liabilities related to continuing operations for the years ended December 31, 2017 and 2016 were as follows (in millions):

Total warranty liability as of December 31, 2015	$	92.3
Payments made in 2016	(24.7		)
Changes resulting from issuance of new warranties	36.2
Changes in estimates associated with pre-existing liabilities	(2.6		)
Changes in foreign currency translation rates and other	(0.1		)
Total warranty liability as of December 31, 2016	$	101.1
Payments made in 2017	(28.8		)
Changes resulting from issuance of new warranties	41.1
Changes in estimates associated with pre-existing liabilities	(4.8		)
Changes in foreign currency translation rates and other	1.3
Total warranty liability as of December 31, 2017	$	109.9

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

During the second quarter of 2017, we identified a product quality issue in a defective vendor-supplied component affecting a product line in the Residential Heating & Cooling segment. This defect has been isolated, the vendor is supplying corrected components, and we are manufacturing product with the corrected components. We have also implemented a program for our dealers to install corrected components in the field. We recorded an expense of $5.7 million for the twelve months ended December 31, 2017, relating to estimated repair costs. The expense related to this product quality issue has been classified in Cost of goods sold in the Consolidated Statements of Operations and the related liability is included in Accrued expenses on the Consolidated Balance Sheet.

Self-Insurance

We use a combination of third-party insurance and self-insurance plans to provide protection against claims relating to workers' compensation/employers' liability, general liability, product liability, auto liability, auto physical damage and other exposures. We use large deductible insurance plans, written through third-party insurance providers, for workers' compensation/employers' liability, general liability, product liability and auto liability. We also carry umbrella or excess liability insurance for all third-party and self-insurance plans, except for directors' and officers' liability, property damage and certain other insurance programs. For directors' and officers' liability, property damage and certain other exposures, we use third-party insurance plans that may include per occurrence and annual aggregate limits. We believe the deductibles and liability limits for all of our insurance policies are appropriate for our business and are adequate for companies of our size in our industry.

We maintain safety and manufacturing programs that are designed to remove risk, improve the effectiveness of our business processes and reduce the likelihood and significance of our various retained and insured risks. In recent years, our actual claims experience has collectively trended favorably and, as a result, both self-insurance expense and the related liability have decreased.

Total self-insurance liabilities were included in the following captions on the accompanying Consolidated Balance Sheets (in millions):

	As of December 31,
	2017				2016
Accrued expenses	$	7.3			$	8.2
Other liabilities	21.6				22.7
Total self-insurance liabilities	$	28.9			$	30.9

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 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 vary depending on several factors, and are subject to policy limits, so we may have greater financial exposure for future settlements and judgments. We currently estimate our probable liability for known and future asbestos-related litigation cases to be between $28.5 million and $46.5 million before consideration of probable insurance recoveries with all amounts in that range equally likely. We have accrued $8.5 million in Accrued expenses and $20.0 million in Other liabilities in the Consolidated Balance at December 31, 2017. For the years ended December 31, 2017, 2016 and 2015, we recorded expense of $3.5 million, $6.3 million and $0.9 million, respectively, net of probable insurance recoveries, for known and future asbestos-related litigation and is recorded in Losses and other expenses, net in the Consolidated Statements of Operations.

In October 2016, we self-reported to the Securities and Exchange Commission (SEC) and the Department of Justice (DOJ) an alleged payment in the amount of 30,000 rubles (approximately US $475) to a Russian customs broker or official. Under the oversight of our Audit Committee, we initiated an investigation into this matter with the assistance of external legal counsel and external forensic accountants.The scope of the investigation was later expanded to include our operations in Poland and Ukraine. The investigation raised questions regarding possible irregularities with respect to non-compliance with customs documents and procedures related to these operations. We continue to fully cooperate with the SEC and the DOJ regarding this matter. We do not anticipate any material adverse effect on our business or financial condition as a result of this matter.

It is management's opinion that none of these claims or lawsuits or any threatened litigation will have a material adverse effect, individually or in the aggregate, 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 in a future period.

11. Lines of Credit and Financing Arrangements:

Short-Term Debt

Foreign Obligations

Through several of our foreign subsidiaries, we have available to us facilities to assist in financing seasonal borrowing needs for our foreign locations. We had $0.9 million and $2.4 million of foreign obligations as of December 31, 2017 and 2016, respectively, that were primarily borrowings under non-committed facilities. Proceeds on these facilities were $30.4 million, $28.4 million and $79.0 million during the years ended December 31, 2017, 2016 and 2015, respectively. Repayments on the facilities were $31.9 million, $30.8 million and $85.4 million during the years ended December 31, 2017, 2016 and 2015, respectively.

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 participating financial institutions for cash. The ASP contains a provision whereby we retain the right to repurchase all of the outstanding beneficial interests transferred. 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 sold under the ASP. The fair values assigned to the retained and transferred interests are based on the sold accounts receivable carrying value given the short term to maturity and low credit risk. The sale of the beneficial interests in our trade accounts receivable are 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.

Prior to the amendment on November 13, 2017, the ASP provided for a maximum securitization amount ranging from $200.0 million to $325.0 million, depending on the period. The ASP was amended effective as of November 13, 2017 to increase the maximum securitization range from $225.0 million to $380.0 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 December 31,
	2017				2016
Eligible amount available under the ASP on qualified accounts receivable	$	290.0			$	250.0
Beneficial interest sold	(276.0		)		(50.0		)
Remaining amount available	$	14.0			$	200.0

We pay certain discount fees to use the ASP and to have the facility available to us. These fees relate to both the used and unused portions of the securitization. The used fee is based on the beneficial interest sold and calculated on either the average LIBOR rate or floating commercial paper rate determined by the purchaser of the beneficial interest, plus a program fee of 0.70%. The average rates as of December 31, 2017 and 2016 were 2.60% and 1.66%, respectively. The unused fee is based on 101% of the maximum available amount less the beneficial interest sold and calculated at a 0.35% fixed rate throughout the term of the agreement. We recorded these fees in Interest expense, net in the accompanying Consolidated Statements of Operations.

The ASP contains certain restrictive covenants relating to the quality of our accounts receivable and cross-default provisions with our Sixth Amended and Restated Credit Facility Agreement ("Domestic Credit Facility"), senior unsecured notes and any

other indebtedness we may have over $75.0 million. The administrative agent under the ASP is also a participant in our Domestic Credit Facility. The participating financial institutions have investment grade credit ratings. We continue to evaluate their credit ratings and have no reason to believe they will not perform under the ASP. As of December 31, 2017, we believe we were in compliance with all covenant requirements.

Long-Term Debt

Domestic Credit Facility

On August 30, 2016, we replaced an earlier credit facility with the Domestic Credit Facility, which consists of a $650.0 million unsecured revolving credit facility and a $250.0 million unsecured term loan and matures in August 2021 (the "Maturity Date"). Under our Domestic Credit Facility, we had outstanding borrowings of $367.0 million, of which $220.0 million was the term loan balance, as well as $2.9 million committed to standby letters of credit as of December 31, 2017. Subject to covenant limitations, $500.1 million was available for future borrowings. The unsecured term loan also matures on the Maturity Date and requires quarterly principal repayments of $7.5 million beginning in March 2017; however, we made $30.0 million of required principal repayments for 2017 in November 2016. The revolving credit facility allows up to $100.0 million of letters of credit to be issued and also includes a subfacility for swingline loans of up to $65.0 million. Additionally, at our request and subject to certain conditions, the commitments under the Domestic Credit Facility may be increased by a maximum of $350.0 million as long as existing or new lenders agree to provide such additional commitments.

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

	As of December 31,
	2017			2016
Weighted average borrowing rate	2.76	%		2.00	%

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

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

Our Domestic Credit Facility contains customary events of default. These events of default include nonpayment of principal or other amounts, material inaccuracy of representations and warranties, breach of covenants or other restrictions or requirements, default on certain other indebtedness or receivables securitizations (cross default), certain voluntary and involuntary bankruptcy events and the occurrence of a change in control. A cross default under our Domestic Credit Facility could occur if:

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

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

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

If any event of default occurs and is continuing, lenders with a majority of the aggregate commitments may require the administrative agent to terminate our right to borrow under our Domestic Credit Facility and accelerate amounts due under our Domestic Credit Facility (except for a bankruptcy event of default, in which case such amounts will automatically become due and payable and the lenders’ commitments will automatically terminate). As of December 31, 2017, we believe we were in compliance with all covenant requirements.

Senior Unsecured Notes

We issued $350.0 million of senior unsecured notes in November 2016 (the "Notes") which will mature on November 15, 2023 with interest being paid on May 15 and November 15 at 3.00% per annum semiannually. We also repaid $200.0 million of senior unsecured notes issued in 2010 which matured on May 15, 2017. The Notes are guaranteed, on a senior unsecured basis, by each of our domestic subsidiaries that guarantee indebtedness under our Domestic Credit Facility. The indenture governing the Notes contains covenants that, among other things, limit our ability and the ability of the subsidiary guarantors to: create or incur certain liens; enter into certain sale and leaseback transactions; and enter into certain mergers, consolidations and transfers of substantially all of our assets. The indenture also contains a cross default provision which is triggered if we default on other debt of at least $75 million in principal which is then accelerated, and such acceleration is not rescinded within 30 days of the notice date. As of December 31, 2017, we believe we were in compliance with all covenant requirements.

12. Employee Benefit Plans:

Over the past several years, we have frozen many of our defined benefit pension and profit sharing plans and replaced them with defined contribution plans. We have a liability for the benefits earned under these inactive plans prior to the date the benefits were frozen. We also have several active defined benefit plans that provide benefits based on years of service. Our defined contribution plans generally include both company and employee contributions which are based on predetermined percentages of compensation earned by the employee.

In addition to freezing the benefits of our defined benefit pension plans, we have also eliminated nearly all of our post-retirement medical benefits. In 2012, we amended the post-retirement benefit plan to shift pre-65 medical coverage for the employees of our largest manufacturing plant so that by 2016, retirees would pay 100% of the cost of post-retirement medical coverage. This change resulted in a significant reduction in the projected benefit obligation for post-retirement medical benefits in 2012.

Effective for fiscal year 2016, we adopted the full yield curve approach for estimating the service cost and interest cost components of expense for plans that use a yield curve to determine the discount rate. The new method applies the specific spot rates along the yield curve used in the most recent measurement of the benefit obligation, resulting in a more precise estimate of expense. The impact for fiscal year 2016 was a decrease in expense of approximately $3.2 million.

In 2016, we offered certain former employees with vested pension benefits a lump sum payout in an effort to reduce our long-term pension obligations. As a result, for 2016, the net periodic benefit cost for our pension plans included a non-cash settlement charge of $31.4 million and the projected benefit obligation decreased by $50.6 million. We did not have similar funding of pension buyout activity in 2017.

Discount rate - interest cost	2.75	%		3.45	%		4.12	%
Expected long-term return on plan assets	4.40	%		4.87	%		5.22	%
Rate of compensation increase	3.78	%		3.70	%		3.48	%

To develop the expected long-term rate of return on assets assumption for the U.S. plans, we considered the historical returns for each asset category, as well as the target asset allocation of the pension portfolio and the effect of periodic balancing. These results were adjusted for the payment of reasonable expenses of the plan from plan assets. This resulted in the selection of the 7.5% long-term rate of return on assets assumption. A similar process was followed for the non-U.S.-based plans.

To select a discount rate for the purpose of valuing the plan obligations for the U.S. plans, we performed an analysis in which the projected cash flows from defined benefit and retiree healthcare plans was matched with a yield curve based on the appropriate universe of high-quality corporate bonds that were available. We used the results of the yield curve analysis to select the discount rate for each plan. The analysis was completed separately for each U.S. pension and OPEB plan. A similar process was followed for the non-U.S.-based plans with sufficient corporate bond information. In other countries, the discount rate was selected based on the approximate duration of plan obligations.

Assumed health care cost trend rates have an effect on the amounts reported for our healthcare plan. The following table sets forth the healthcare trend rate assumptions used:

	2017			2016
Assumed health care cost trend rates as of December 31:
Health care cost trend rate assumed for next year	6.50	%		6.50	%
Rate to which the cost rate is assumed to decline (the ultimate trend rate)	5.00	%		5.00	%
Year that the rate reaches the ultimate trend rate	2021			2020

A one percentage-point change in assumed healthcare cost trend rates would have the following effects (in millions):

Pension Plan Assets

We believe asset returns can be optimized at an acceptable level of risk by adequately diversifying the plan assets between equity and fixed income. In the second quarter of 2017, in order to decrease volatility, we changed the targeted allocations for our plan assets. The targeted allocation for fixed income, money market and cash investments was changed to 75%, and the targeted allocation for equity investments was changed to 25%. Our targeted exposure to International equity including emerging markets was changed to 12.5% of total assets and our exposure to domestic equity was changed to 12.5%. Our U.S. pension plan represents 87%, our Canadian pension plan 6%, and our United Kingdom (“U.K.”) pension plan 7% of the total fair value of our plan assets as of December 31, 2017.

Our U.S. pension plans' weighted-average asset allocations as of December 31, 2017 and 2016, by asset category, are as follows:

	Plan Assets as of December 31,
Asset Category:	2017			2016
U.S. equity	12.5	%		27.0	%
International equity	15.1	%		18.5	%
Fixed income	71.1	%		52.5	%
Money market/cash	1.3	%		2.0	%
Total	100.0	%		100.0	%

U.S. pension plan assets are invested according to the following targets:

Asset Category:	Target
U.S. equity	12.5	%
International equity	12.5	%
Fixed income	73.0	%
Money market/cash	2.0	%

Our Canadian pension plans were invested approximately 75% in Canadian bonds and 25% in international equities. Our U.K. pension plan was invested in a broad mix of assets consisting of U.K. and international equities, and U.K. fixed income securities, including corporate and government bonds.

The majority of our commingled pool/collective trusts, mutual funds, balanced pension trusts and pension funds are managed by professional investment advisors. The NAVs per share are furnished in monthly and/or quarterly statements received from the investment advisors and reflect valuations based upon their pricing policies. We assessed the fair value classification of these investments as Level 2 for commingled pool/collective trusts, balanced pension trusts and pension funds based on an examination of their pricing policies and the related controls and procedures. The fair values we report are based on the pool, trust or fund's NAV per share. The NAVs per share are calculated periodically (daily or no less than one time per month) as the aggregate value of each pool or trust's underlying assets divided by the number of units owned. See Note 19 for information about our fair value hierarchies and valuation techniques.

Incentive Plan

Under the Lennox International Inc. 2010 Incentive Plan, as amended and restated (the “2010 Incentive Plan”), we are authorized to issue awards for 24.3 million shares of common stock. The 2010 Incentive Plan provides for various long-term incentive awards, including performance share units, restricted stock units and stock appreciation rights. A description of these long-term incentive awards and related activity within each award category is provided below.

As of December 31, 2017, awards for 13.5 million shares of common stock had been granted, net of cancellations and repurchases, and there were 3.4 million shares available for future issuance.

Performance Share Units

Performance share units are granted to certain employees at the discretion of the Board of Directors with a three-year performance period beginning January 1st of each year. Upon meeting the performance and vesting criteria, performance share units are converted to an equal number of shares of our common stock. Performance share units vest if, at the end of the three-year performance period, at least the threshold performance level has been attained. To the extent that the payout level attained is less than 100%, the difference between 100% and the units earned and distributed will be forfeited. Eligible participants may also earn additional units of our common stock, which would increase the potential payout up to 200% of the units granted, depending on LII's performance over the three-year performance period.

Performance share units are classified as equity awards. Compensation expense is recognized on an earnings curve over the period and is based on the expected number of units to be earned and the fair value of the stock at the date of grant. The fair value of units is calculated as the average of the high and low market price of the stock on the date of grant discounted by the expected dividend rate over the service period. The number of units expected to be earned will be adjusted in future periods as necessary to reflect changes in the estimated number of award to be issued and, upon vesting, the actual number of units awarded. Our practice is to issue new shares of common stock or utilize treasury stock to satisfy performance share unit distributions.

The following table provides information on our performance share units:

	For the Years Ended December 31,
	2017				2016				2015
Compensation expense for performance share units (in millions)	$	12.2			$	18.1			$	13.6

Payout ratio for shares paid	185.9		%		200.0		%		200.0		%

A summary of the status of our undistributed performance share units as of December 31, 2017, and changes during the year then ended, is presented below (in millions, except per share data):

	Shares (2)			Weighted- Average Grant Date Fair Value per Share
Undistributed performance share units as of December 31, 2016	0.4			$	101.03
Granted	0.1			197.54
Adjustment to shares paid based on payout ratio	0.1			88.26
Distributed	(0.2	)		81.17
Forfeited	—			—
Undistributed performance share units as of December 31, 2017 (1)	0.3			$	123.80

(1) Undistributed performance share units include approximately 0.2 million units with a weighted-average grant date fair value of $154.90 per share that had not yet vested and 0.2 million units that have vested but were not yet distributed.

(2) Share amounts are rounded but the balance of undistributed performance share units as of December 31, 2017 accurately reflects actual units undistributed.

As of December 31, 2017, we had $20.7 million of total unrecognized compensation cost related to non-vested performance share units that is expected to be recognized over a weighted-average period of 2.2 years. Our estimated forfeiture rate for these performance share units was 15.1% as of December 31, 2017.

The total fair value of performance share units distributed and the resulting tax deductions to realize tax benefits were as follows (in millions):

	For the Years Ended December 31,
	2017				2016				2015
Fair value of performance share units distributed	$	64.3			$	39.4			$	44.9
Realized tax benefits from tax deductions	$	24.5			$	15.0			$	17.1

Restricted Stock Units

Restricted stock units are issued to attract and retain key employees. Generally, at the end of a three-year retention period, the units will vest and be distributed in shares of our common stock to the participant. Our practice is to issue new shares of common stock or utilize treasury stock to satisfy restricted stock unit vestings. Restricted stock units are classified as equity awards. The fair value of units granted is the average of the high and low market price of the stock on the date of grant discounted by the expected dividend rate over the service period. Units are amortized to compensation expense ratably over the service period.

The following table provides information on our restricted stock units (in millions, except per share data):

	For the Years Ended December 31,
	2017				2016				2015
Compensation expense for restricted stock units	$	8.3			$	9.0			$	8.3
Weighted-average fair value of grants, per share	$	197.54			$	150.14			$	126.15

A summary of our non-vested restricted stock units as of December 31, 2017 and changes during the year then ended is presented below (in millions, except per share data):

	Shares(2)			Weighted- Average Grant Date Fair Value per Share
Non-vested restricted stock units as of December 31, 2016	0.3			$	118.38
Granted	0.1			197.54
Distributed	(0.1	)		89.33
Forfeited	—			—
Non-vested restricted stock units as of December 31, 2017(1)	0.2			$	156.16

(1) As of December 31, 2017, we had $18.8 million of total unrecognized compensation cost related to non-vested restricted stock units that is expected to be recognized over a weighted-average period of 2.4 years. Our estimated forfeiture rate for restricted stock units was 18.2% as of December 31, 2017.

(2) Share amounts are rounded but the balance of undistributed performance share units as of December 31, 2017 accurately reflects actual units undistributed.

The total fair value of restricted stock units vested and the resulting tax deductions to realize tax benefits were as follows (in millions):

	For the Years Ended December 31,
	2017				2016				2015
Fair value of restricted stock units vested	$	19.0			$	17.0			$	19.7
Realized tax benefits from tax deductions	7.2				6.5				7.5

Stock Appreciation Rights

Stock appreciation rights are issued to certain key employees. Each recipient is given the “right” to receive compensation, paid in shares of our common stock, equal to the future appreciation of our common stock price. Stock appreciation rights generally vest in one-third increments beginning on the first anniversary date after the grant date and expire after seven years. Our practice is to issue new shares of common stock or utilize treasury stock to satisfy the exercise of stock appreciation rights.

The following table provides information on our stock appreciation rights (in millions, except per share data):

	For the Years Ended December 31,
	2017				2016				2015
Compensation expense for stock appreciation rights	$	4.4			$	4.6			$	4.7
Weighted-average fair value of grants, per share	32.32				22.93				22.74

Compensation expense for stock appreciation rights is based on the fair value on the date of grant, estimated using the Black-Scholes-Merton valuation model, and is recognized over the service period. We used historical stock price data to estimate the expected volatility. We determined that the recipients of stock appreciation rights can be combined into one employee group that has similar historical exercise behavior and we used our historical pattern of award exercises to estimate the expected life of the awards for the employee group. The risk-free interest rate was based on the zero-coupon U.S. Treasury yield curve with a maturity equal to the expected life of the awards at the time of grant.

The fair value of the stock appreciation rights granted in 2017, 2016 and 2015 were estimated on the date of grant using the following assumptions:

	2017			2016			2015
Expected dividend yield	1.47	%		1.62	%		1.61	%
Risk-free interest rate	2.02	%		1.66	%		1.36	%
Expected volatility	19.97	%		19.60	%		23.78	%
Expected life (in years)	3.95			3.99			4.00

A summary of our stock appreciation rights as of December 31, 2017, and changes during the year then ended, is presented below (in millions, except per share data):

Employee Stock Purchase Plan

Under the 2012 Employee Stock Purchase Plan (“ESPP”), all employees who meet certain service requirements are eligible to purchase our common stock through payroll deductions at the end of three month offering periods. The purchase price for such shares is 95% of the fair market value of the stock on the last day of the offering period. A maximum of 2.5 million shares is authorized for purchase until the ESPP plan termination date of May 10, 2022, unless terminated earlier at the discretion of the Board of Directors. Employees purchased approximately 16,000 shares under the ESPP during the year ended December 31, 2017. Approximately 2.4 million shares remain available for purchase under the ESPP as of December 31, 2017.

15. Stock Repurchases:

Our Board of Directors has authorized a total of $2 billion towards the repurchase of shares of our common stock (collectively referred to as the "Share Repurchase Plans"), including a $550 million share repurchase authorization in 2016. The Share Repurchase Plans authorize open market repurchase transactions and do not have a stated expiration date. As of December 31, 2017, $396.0 million of shares may still be repurchased under the Share Repurchase Plans.

On February 9, 2017, the Company entered into a Fixed Dollar Accelerated Share Repurchase Transaction (the “ASR Agreement”) with Morgan Stanley, to effect an accelerated stock buyback of our common stock. Under the ASR Agreement, on February 9, 2017, we paid Morgan Stanley an initial purchase price of $75 million, and Morgan Stanley delivered to us common stock, representing approximately 85% of the shares expected to be purchased under the ASR Agreement. The ASR Agreement was completed in the second quarter and Morgan Stanley delivered additional shares for a total of 0.5 million shares of common stock repurchased as part of this ASR Agreement.

On April 28, 2017, we entered into another Fixed Dollar ASR Agreement (the "Second ASR Agreement") with J.P. Morgan Chase Bank to effect an accelerated stock buyback of common stock. Under the Second ASR Agreement, on April 28, 2017, we paid J.P. Morgan Chase Bank an initial purchase price of $100 million, and J.P. Morgan Chase Bank delivered to us common stock, representing approximately 85% of the shares expected to be purchased under the ASR Agreement. The ASR Agreement was completed in the third quarter and J.P. Morgan Chase Bank delivered additional shares for a total of 0.6 million shares of common stock repurchased as part of this ASR Agreement.

On July 27, 2017, we entered into another Fixed Dollar ASR Agreement (the "Third ASR Agreement") with Bank of America to effect an accelerated stock buyback of common stock. Under the Third ASR Agreement, on July 27, 2017, we paid Bank of America an initial purchase price of $75 million, and Bank of America delivered to us common stock, representing approximately 85% of the shares expected to be purchased under the third ASR Agreement. The ASR Agreement was completed in the fourth quarter and Bank of America delivered additional shares for a total of 0.4 million shares of common stock repurchased as part of this ASR Agreement.

We also repurchased 0.1 million shares for $26.1 million and 0.2 million shares for $33.3 million for the years ended December 31, 2017 and 2016, respectively, from employees who surrendered their shares to satisfy minimum tax withholding obligations upon the vesting of stock-based compensation awards.

16. Restructuring Charges:

We record restructuring charges associated with management-approved restructuring plans to reorganize or to remove duplicative headcount and infrastructure within our businesses. Restructuring charges include severance costs to eliminate a specified number of employees, infrastructure charges to vacate facilities and consolidate operations, contract cancellation costs and other related activities. The timing of associated cash payments is dependent upon the type of restructuring charge and can extend over a multi-year period. Restructuring charges are not included in our calculation of segment profit (loss), as more fully explained in Note 18.

Restructuring Activities in 2017

Information regarding the restructuring charges for all ongoing activities are presented in the table below (in millions):

	Incurred in 2017				Incurred to Date				Total Expected to be Incurred

Lease termination	—				0.2				0.2
Other	0.4				4.1				4.5
Total	$	3.2			$	18.8			$	19.4

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

	Incurred in 2017				Incurred to Date				Total Expected to be Incurred
Residential Heating & Cooling	$	0.5			$	1.4			$	1.4

17. Earnings Per Share:

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

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

	For the Years Ended December 31,
	2017				2016				2015
Net income	$	305.7			$	277.8			$	186.6
Add: Loss from discontinued operations	1.4				0.8				0.6
Income from continuing operations	$	307.1			$	278.6			$	187.2
Weighted-average shares outstanding – basic	42.2				43.4				44.9
Add: Potential effect of diluted securities attributable to stock-based payments	0.6				0.6				0.7
Weighted-average shares outstanding – diluted	42.8				44.0				45.6
Earnings per share - Basic:
Income from continuing operations	$	7.28			$	6.41			$	4.17
Loss from discontinued operations	(0.03		)		(0.02		)		(0.01		)
Net income	$	7.25			$	6.39			$	4.16
Earnings per share - Diluted:
Income from continuing operations	$	7.17			$	6.34			$	4.11
Loss from discontinued operations	(0.03		)		(0.02		)		(0.02		)
Net income	$	7.14			$	6.32			$	4.09

An insignificant number of stock appreciation rights were outstanding but not included in the diluted earnings per share calculation because the assumed exercise of such rights would have been anti-dilutive.

18. Reportable Business Segments:

Description of 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		Products 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, variable refrigerant flow commercial products		Light Commercial		United States Canada Europe
Refrigeration		Condensing units, unit coolers, fluid coolers, air- cooled condensers, air handlers, process chillers, controls, compressorized racks, supermarket display cases and systems		Light Commercial; Food Preservation; Non-Food/Industrial		United States Canada Europe Asia Pacific South America

Segment Data

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 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 recorded 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 included in the results presented in the table below.

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

19. Fair Value Measurements:

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date and requires consideration of our creditworthiness when valuing certain liabilities. Our framework for measuring fair value is based on the following three-level hierarchy for fair value measurements:

Level 1 - Quoted prices for identical instruments in active markets at the measurement date.

Level 2 -	Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets at the measurement date and for the anticipated term of the instrument.

Level 3 -	Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable inputs that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

Where available, the fair values were based upon quoted prices in active markets. However, if quoted prices were not available, then the fair values were based upon quoted prices for similar assets or liabilities or independently sourced market parameters, such as credit default swap spreads, yield curves, reported trades, broker/dealer quotes, interest rates and benchmark securities. For assets and liabilities without observable market activity, if any, the fair values were based upon discounted cash flow methodologies incorporating assumptions that, in our judgment, reflect the assumptions a marketplace participant would use. Valuation adjustments to reflect either party's creditworthiness and ability to pay were incorporated into our valuations, where appropriate, as of December 31, 2017 and 2016, the measurement dates. The methodologies used to determine the fair value of our financial assets and liabilities as of December 31, 2017 were the same as those used as of December 31, 2016.

Fair values are estimates and are not necessarily indicative of amounts for which we could settle such instruments currently nor indicative of our intent or ability to dispose of or liquidate them.

Assets and Liabilities Carried at Fair Value on a Recurring Basis

Derivatives

Derivatives, classified as Level 2, were 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, but they were insignificant to the overall value of the derivatives. Refer to Note 8 for more information related to our derivative instruments.

Marketable Equity Securities

The following table presents the fair values of an investment in marketable equity securities, related to publicly traded stock of a non-U.S. company, recorded in Other assets, net in the accompanying Consolidated Balance Sheets (in millions):

	As of December 31,
	2017				2016
Quoted Prices in Active Markets for Identical Assets (Level 1):
Investment in marketable equity securities	$	4.1			$	4.4

Other Fair Value Disclosures

The carrying amounts of Cash and cash equivalents, Accounts and notes receivable, net, Accounts payable, Other current liabilities, 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 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 the fair value for our senior unsecured notes in Long-term debt (in millions):

	As of December 31,
	2017				2016
Quoted Prices in Active Markets for Similar Instruments (Level 2):
Senior unsecured notes	$	308.1			$	499.3

20. Selected Quarterly Financial Information (unaudited):

(1) The sum of the quarterly results for each of the four quarters may not equal the full year results due to rounding.

(2) EPS for each quarter is computed using the weighted-average number of shares outstanding during that quarter, while EPS for the fiscal year is computed using the weighted-average number of shares outstanding during the year. Thus, the sum of the EPS for each of the four quarters may not equal the EPS for the fiscal year.

23. Condensed Consolidating Financial Statements:

The Company’s senior unsecured notes are unconditionally guaranteed by certain of the Company’s subsidiaries (the “Guarantor

Subsidiaries”) and are not secured by our other subsidiaries (the “Non-Guarantor Subsidiaries”). The Guarantor Subsidiaries are 100% owned, all guarantees are full and unconditional, and all guarantees are joint and several. As a result of the guarantee arrangements, we are required to present condensed consolidating financial statements.

The condensed consolidating financial statements reflect the investments in subsidiaries of the Company using the equity method of accounting. The principal elimination entries eliminate investments in subsidiaries and intercompany balances and transactions.

Condensed consolidating financial statements of the Company, its Guarantor Subsidiaries and Non-Guarantor Subsidiaries as of December 31, 2017 and December 31, 2016 and for the years ended December 31, 2017, 2016 and 2015 are shown on the following pages.
