Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	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, 2015, the accompanying unaudited Consolidated Statements of Operations for the three months ended March 31, 2015 and 2014, the accompanying unaudited Consolidated Statements of Comprehensive Income for the three months ended March 31, 2015 and 2014, and the accompanying unaudited Consolidated Statements of Cash Flows for the three months ended March 31, 2015 and 2014 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, 2014. The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. 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 each quarter is 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, 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 combine to increase the uncertainty inherent in such estimates and assumptions. Future events and their effects cannot be determined with precision and actual results could differ significantly from these estimates. Changes in these estimates will be reflected in the financial statements in future periods.
	Reclassifications
	Certain amounts have been reclassified from the prior year presentation to conform to the current year presentation.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives:
	Objectives and Strategies for Using Derivative Instruments
	Commodity Price Risk - We utilize a cash flow hedging program to mitigate our exposure to volatility in the prices of metal commodities used in our production processes. Our hedging program includes the use of futures contracts to lock in prices, and as a result, we are subject to derivative losses should the metal commodity prices decrease and gains should the prices increase. We utilize a dollar cost averaging strategy so that a higher percentage of commodity price exposures are hedged near-term and lower percentages hedged at future dates. This strategy allows for protection against near-term price volatility while allowing us to adjust to market price movements over time.
	Interest Rate Risk - A portion of our debt bears interest at variable rates, and as a result, we are subject to variability in the cash paid for interest. To mitigate a portion of that risk, we may choose to engage in an interest rate swap hedging strategy to eliminate the variability of interest payment cash flows. We are not currently hedged against interest rate risk.
	Foreign Currency Risk - Foreign currency exchange rate movements create a degree of risk by affecting the U.S. dollar value of assets and liabilities arising in foreign currencies. We seek to mitigate the impact of currency exchange rate movements on certain short-term transactions by periodically entering into foreign currency forward contracts. These forward contracts are not designated as hedges and generally expire during the quarter that we enter into them. By entering into forward contracts, we lock in exchange rates that would otherwise cause losses should the U.S. dollar appreciate and gains should the U.S. dollar depreciate.
	Cash Flow Hedges
	We have commodity futures contracts designated as cash flow hedges that are scheduled to mature through September 2016. Unrealized gains or losses from our cash flow hedges are included in accumulated other comprehensive loss (“AOCL”) and are expected to be reclassified into earnings within the next 18 months based on the prices of the commodities at the settlement dates.
	We recorded the following amounts in AOCL related to our cash flow hedges (in millions):
		As of March 31, 2015				As of December 31, 2014
	Unrealized losses on unsettled futures contracts	$	5.8			$	7.2
	Income tax benefit	(2.1		)		(2.6		)
	Losses included in AOCL, net of tax (1)	$	3.7			$	4.6
	(1) Assuming commodity prices remain constant, we expect to reclassify $3.8 million of derivative losses 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 March 31, 2015			As of December 31, 2014
	Copper	24.9			29.4
	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 March 31, 2015			As of December 31, 2014
	Copper	2.5			2.9
	Aluminum	2.5			2.2

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes:
	As of March 31, 2015, we had approximately $1.6 million in total gross unrecognized tax benefits. Of this amount, $1.2 million (net of federal benefit on state issues), if recognized, would be recorded through the Consolidated Statement of Operations. As of March 31, 2015, we had approximately $0.2 million (net of federal tax benefits) in interest and penalties recognized in income tax expense in accordance with FASB Accounting Standards Codification ("ASC") Topic 740.
	We are currently under examination for our U.S. federal income taxes under the Internal Revenue Service's Compliance Assurance Program for 2015 and 2014 and are subject to examination by numerous other taxing authorities in the U.S. and in jurisdictions such as Australia, Belgium, France, Canada, and Germany. We are generally no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by taxing authorities for years prior to 2009.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies:
	Product Warranties and Product Related Contingencies
	We offer warranties to customers for some of our products and record liabilities for estimated future warranty-related costs based on failure rates, cost experience and other factors. We periodically review the assumptions used to determine the product warranty liabilities and will adjust the liabilities in future periods for changes in assumptions, as necessary.
	Liabilities for estimated product warranty costs related to continuing operations are included in the following captions on the accompanying Consolidated Balance Sheets (in millions):
		As of March 31, 2015			As of December 31, 2014
	Accrued expenses	$	26.3		$	27.3
	Other liabilities	60.3			59.9
	Total warranty liability	$	86.6		$	87.2
	The changes in product warranty liabilities related to continuing operations for the three months ended March 31, 2015 were as follows (in millions):
	Total warranty liability as of December 31, 2014	$	87.2
	Warranty claims paid	(4.7		)
	Changes resulting from issuance of new warranties	6.4
	Changes in estimates associated with pre-existing liabilities	(1.2		)
	Changes in foreign currency translation rates and other	(1.1		)
	Total warranty liability as of March 31, 2015	$	86.6
	We have incurred, and will likely continue to incur, product costs not covered by insurance or our suppliers’ warranties.   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.   We currently estimate our probable liability for a supplier quality issue within a range of $2.2 million and $6 million; accordingly, we have accrued a $2.2 million liability in Accrued Expenses on the Consolidated Balance Sheet because all amounts in that range were equally likely. The supplier has agreed to reimburse our costs related to this liability; accordingly, we have also recorded a receivable of $2.2 million in Other Assets on the Consolidated Balance Sheet.  If additional costs are incurred, we expect the supplier will also reimburse those costs. The $2.2 million accrual is not included in the estimated warranty liabilities tables immediately above.
	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. Costs related to such matters were not material to the periods presented.
	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. As a result, we may have greater financial exposure for future settlements and judgments. For the three months ended March 31, 2015, and 2014, expense for asbestos-related litigation was $0.1 million, and $0.2 million, net of insurance recoveries, respectively.
	We are the defendant in an attempted class action lawsuit alleging evaporator coils in our residential air conditioning products are susceptible to a type of corrosion that can result in coil leaks.  We dispute the allegations in the lawsuit.  We have reached tentative settlement terms and recorded a liability of $2.4 million in Accrued Expenses on the Consolidated Balance Sheet.   Any additional liability resulting from the proposed settlement is not currently reasonably estimable, but we do not expect the proposed settlement to have a material adverse effect on our financial condition or results of operations.
	It is management's opinion that none of these claims or lawsuits or any threatened litigation will have a material adverse effect on our financial condition, results of operations or cash flows. Claims and lawsuits, however, involve uncertainties and it is possible that their eventual outcome could adversely affect our results of operations for a particular period.

	Foreign Obligations
	Through several of our foreign subsidiaries, we have facilities available to assist in financing seasonal borrowing needs for our foreign locations. We had $5.3 million and $6.6 million of foreign obligations as of March 31, 2015 and December 31, 2014, respectively, that were primarily borrowings under non-committed facilities. Proceeds on these facilities were $11.0 million and $20.6 million during the three months ended March 31, 2015 and 2014, respectively. Repayments on the facilities were $11.2 million and $18.1 million and during the three months ended March 31, 2015 and 2014, 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 is subject to annual renewal and 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 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 short-term 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.
	In November 2014, we amended the ASP, extending its term to November 13, 2015 and increasing the maximum securitization amount from a range of $160.0 million to $220.0 million to a range of $180.0 million to $220.0 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 March 31, 2015			As of December 31, 2014
	Eligible amount available under the ASP on qualified accounts receivable	$	180		$	220
	Beneficial interest sold	180			220
	Remaining amount available	$	—		$	—
	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 the average LIBOR rate or floating commercial paper rate determined by the purchaser of the beneficial interest, plus a program fee of 0.60%. The average rate for both March 31, 2015 and December 31, 2014 was 0.79%. The unused fee is based on 101% of the maximum available amount less the beneficial interest sold and is calculated at a 0.30% fixed rate throughout the term of the agreement. In addition, a 0.05% unused fee is charged on incremental available amounts above $180 million during certain months of the year. 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 certain cross-default provisions with our Fifth 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 March 31, 2015, we were in compliance with all covenant requirements.
	Long-Term Debt
	Domestic Credit Facility
	On November 13, 2014, we replaced our $650 million Domestic Revolving Credit Facility with a $950 million Domestic Credit Facility, which consists of a $650 million revolving credit facility and a $300 million term loan and matures in November 2019 (the "Maturity Date"). Under our $950.0 million Domestic Credit Facility, we had outstanding borrowings of $683.5 million as well as $27.2 million committed to standby letters of credit as of March 31, 2015. Subject to covenant limitations, $239.3 million was available for future borrowings. The unsecured $300 million term loan also matures on the Maturity Date and requires quarterly principal repayments of $7.5 million beginning on June 30, 2015. The revolving credit facility allows up to $150 million of letters of credit to be issued and also includes a subfacility for swingline loans of up to $65 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 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 March 31, 2015		As of December 31, 2014
	Weighted average borrowing rate	1.66	%	1.88	%
	Our Domestic Credit Facility is guaranteed by certain of our subsidiaries and contains financial covenants relating to leverage and interest coverage. Other covenants contained in the Domestic Credit Facility restrict, among other things, certain mergers, asset dispositions, guarantees, debt, liens, and affiliate transactions. The financial covenants require us to maintain a defined Consolidated Indebtedness to Adjusted EBITDA Ratio and a Cash Flow (defined as EBITDA minus capital expenditures) to Net
	Interest Expense Ratio. The required ratios under our Domestic Credit Facility are detailed below:
	Consolidated Indebtedness to Adjusted EBITDA Ratio no greater than	3.5 : 1.0
	Cash Flow to Net Interest Expense Ratio no less than	3.0 : 1.0
	Our Domestic Credit Facility contains customary events of default. These events of default include nonpayment of principal or interest, breach of covenants or other restrictions or requirements, default on certain other indebtedness or receivables securitizations (cross default), and bankruptcy. A cross default under our Domestic Credit Facility could occur if:
	•	We fail to pay any principal or interest when due on any other indebtedness or receivables securitization of at least $75.0 million; or
	•	We are in default in the performance of, or compliance with any term of any other indebtedness or receivables securitization in an aggregate principal amount of at least $75.0 million or any other condition exists which would give the holders the right to declare such indebtedness due and payable prior to its stated maturity.
	Each of our major debt agreements contains provisions by which a default under one agreement causes a default in the others (a "cross default"). If a cross default under the Domestic Credit Facility, our senior unsecured notes, the Lake Park Renewal (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 March 31, 2015, we were in compliance with all covenant requirements.
	Senior Unsecured Notes
	We issued $200.0 million of senior unsecured notes in May 2010 through a public offering. Interest is paid semiannually on May 15 and November 15 at a fixed interest rate of 4.90% per annum. These notes mature on May 15, 2017. The notes are guaranteed, on a senior unsecured basis, by each of our domestic subsidiaries that guarantee payment by us of any 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; enter into certain mergers, consolidations and transfers of substantially all of our assets; and transfer certain properties. The indenture also contains a cross default provision which is triggered if we default on other debt of at least $75.0 million in principal which is then accelerated, and such acceleration is not rescinded within 30 days of the notice date. As of March 31, 2015, we were in compliance with all covenant requirements.

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 15.

(the "Buyer") in an all-cash transaction for net proceeds of $10.4 million, excluding transaction costs. We also entered into a two-year equipment and parts supply agreement with the Buyer. In April 2012, we sold our Hearth business to Comvest Investment Partners IV in an all-cash transaction for net proceeds of $10.1 million, excluding the transaction costs and cash transferred with the business.
	There were no assets and liabilities related to the Service Experts or Hearth businesses included in the accompanying Consolidated Balance Sheets as of March 31, 2015 or December 31, 2014, except for insurance casualty loss reserves which we retained after the respective transactions.

Earnings Per Share [Abstract]
Earnings Per Share	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 Net income were as follows (in millions, except per share data):
		For the Three Months Ended March 31,
		2015		2014

Segment Reporting [Abstract]
Reportable Business Segments	Reportable Business Segments:
	We operate in three reportable business segments of the heating, ventilation, air conditioning and refrigeration (“HVACR”) industry. Our segments are organized primarily by the nature of the products and services we provide. The following table describes each segment:
	Segment		Product or Services		Markets Served		Geographic Areas
	Residential Heating & Cooling		Furnaces, air conditioners, heat pumps, packaged heating and cooling systems, indoor air quality equipment, comfort control products, replacement parts		Residential Replacement;		United States
					Residential New Construction		Canada
	Commercial Heating & Cooling		Unitary heating and air conditioning equipment, applied systems, controls, installation and service of commercial heating and cooling equipment		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;		United States
					Food Preservation;		Canada
					Non-Food/Industrial		Europe
							Asia Pacific
							South America
	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.
	As they arise, transactions between segments are recorded on an arm’s-length basis using the relevant market prices. Any intercompany sales and associated profit (and any other intercompany items) are eliminated from segment results. There were no significant intercompany eliminations for the periods presented as follows.
	Segment Data
	Net sales and segment profit (loss) for each segment, along with a reconciliation of segment profit (loss) to Income from continuing operations before income taxes, are shown below (in millions):
		For the Three Months Ended March 31,

Fair Value Measurements	Fair Value Measurements:
	Fair Value Hierarchy
	The methodologies used to determine the fair value of our financial assets and liabilities at March 31, 2015 were the same as those used at December 31, 2014.
	Assets and Liabilities Carried at Fair Value on a Recurring Basis
	Derivatives
	Derivatives were classified as Level 2 and primarily valued using estimated future cash flows based on observed prices from exchange-traded derivatives. We also considered the counterparty's creditworthiness, or our own creditworthiness, as appropriate. Adjustments were recorded to reflect the risk of credit default, however, they were insignificant to the overall value of the derivatives. Refer to Note 4 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, classified as Level 1 and 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 March 31, 2015		As of December 31, 2014
	Investment in marketable equity securities	$	5.5	$	5.3
	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, classified as Level 2, was based on the amount of future cash flows using current market rates for debt instruments of similar maturities and credit risk. The following table presents their fair value (in millions):
		As of March 31, 2015		As of December 31, 2014
	Senior unsecured notes	$	214.8	$	210.6

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation
	The accompanying unaudited Consolidated Balance Sheet as of March 31, 2015, the accompanying unaudited Consolidated Statements of Operations for the three months ended March 31, 2015 and 2014, the accompanying unaudited Consolidated Statements of Comprehensive Income for the three months ended March 31, 2015 and 2014, and the accompanying unaudited Consolidated Statements of Cash Flows for the three months ended March 31, 2015 and 2014 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, 2014. The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. 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 each quarter is 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	Use of Estimates
	The preparation of financial statements requires us to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangible assets and other long-lived assets, contingencies, guarantee obligations, indemnifications, and assumptions used in the calculation of income taxes, pension and post-retirement medical benefits, and stock-based compensation among others. These estimates and assumptions are based on our best estimates and judgment.
	We evaluate these estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. We believe these estimates and assumptions to be reasonable under the circumstances and will adjust such estimates and assumptions when facts and circumstances dictate. Volatile equity, foreign currency and commodity markets combine to increase the uncertainty inherent in such estimates and assumptions. Future events and their effects cannot be determined with precision and actual results could differ significantly from these estimates. Changes in these estimates will be reflected in the financial statements in future periods.
Reclassifications	Reclassifications
	Certain amounts have been reclassified from the prior year presentation to conform to the current year presentation.
