1. General:

References in this Quarterly Report on Form 10-Q to “we,” “our,” “us,” “LII” or the “Company” refer to Lennox International Inc. and its subsidiaries, unless the context requires otherwise.

Basis of Presentation

The accompanying unaudited Consolidated Balance Sheet as of March 31, 2012, the accompanying unaudited Consolidated Statements of Operations for the three months ended March 31, 2012 and 2011, the unaudited Consolidated Statements of Comprehensive Income for the three months ended March 31, 2012 and 2011, and the accompanying unaudited Consolidated Statements of Cash Flows for the three months ended March 31, 2012 and 2011 should be read in conjunction with our audited consolidated financial statements and footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2011. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The accompanying consolidated financial statements contain all material adjustments, consisting principally of normal recurring adjustments, necessary for a fair presentation of our financial position, results of operations and cash flows. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to applicable rules and regulations, although we believe that the disclosures herein are adequate to make the information presented not misleading. The operating results for the interim periods are not necessarily indicative of the results that may be expected for a full year.

Our fiscal year ends on December 31 and our quarters are each comprised of 13 weeks. For convenience, throughout these financial statements, the 13 weeks comprising each quarterly period are denoted by the last day of the respective calendar quarter.

Use of Estimates

The preparation of financial statements requires us to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangible assets, and other long-lived assets, contingencies, guarantee obligations, indemnifications, and assumptions used in the calculation of income taxes, and pension and postretirement medical benefits, among others. These estimates and assumptions are based on management’s 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 adjust such estimates and assumptions when facts and circumstances dictate.

Reclassifications

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

New Accounting Pronouncements

In June 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income (“ASU 2011-05”). This ASU eliminates the option to present the components of other comprehensive income as part of the statement of stockholders’ equity. Rather, it gives an entity the choice to present the components of net income and other comprehensive income in either a single continuous statement or two separate but consecutive statements. The components of comprehensive income and timing of reclassification of an item to net income do not change with this update. ASU 2011-05 requires retrospective application and is effective for annual and interim periods beginning after December 15, 2011. We adopted this ASU in the first quarter of 2012 and have presented separate Consolidated Statements of Comprehensive Income.

In September 2011, the FASB issued ASU No. 2011-08, Intangibles – Goodwill and Other (Topic 350):Testing Goodwill for Impairment (“ASU 2011-08”) related to goodwill impairment guidance. This ASU gives an option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If after assessing all events and circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, the performance of the two-step impairment test is unnecessary. The effective date is for fiscal years beginning after December 15, 2011. We adopted this ASU in the first quarter of 2012. See Note 3 for the results of our annual goodwill impairment test.

In December 2011, the FASB issued ASU No. 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05. This ASU defers including the reclassification adjustments in the income statement but does not defer reclassification adjustments in other comprehensive income. We have included the reclassification adjustments in other comprehensive income in the Consolidated Statements of Comprehensive Income as allowed in this ASU.
