Accounting Policies [Abstract]
Significant Accounting Policies	Note 1 – Significant Accounting Policies
	Basis of Presentation. The consolidated financial statements of Brunswick Corporation (Brunswick or the Company) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain previously reported amounts have been reclassified to conform to the current period presentation. As indicated in Note 2 – Discontinued Operations, Brunswick's results as discussed in the financial statements reflect continuing operations only, unless otherwise noted.
	Principles of Consolidation. The consolidated financial statements of Brunswick include the accounts of all majority owned and controlled domestic and foreign subsidiaries. Intercompany balances and transactions have been eliminated.
	Use of Estimates. The preparation of the consolidated financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates. Actual results could differ materially from those estimates. These estimates affect:
	•The reported amounts of assets and liabilities at the date of the financial statements;
	•	The disclosure of contingent assets and liabilities at the date of the financial statements; and
	•The reported amounts of revenues and expenses during the reporting periods.
	Estimates in these consolidated financial statements include, but are not limited to:
	•Allowances for doubtful accounts;
	•Inventory valuation reserves;
	•Reserves for dealer allowances;
	•Reserves related to repurchase and recourse obligations;
	•Warranty related reserves;
	•Losses on litigation and other contingencies;
	•Environmental reserves;
	•Insurance reserves;
	•Valuation of goodwill and other intangible assets;
	•Impairments of long-lived assets;
	•Reserves related to restructuring activities;
	•Postretirement benefit liabilities;
	•Valuation allowances on deferred tax assets; and
	•Income tax reserves.
	The Company records a reserve when it is probable that a loss has been incurred and the loss can be reasonably estimated. The Company establishes its reserves based on its best estimate within a range of losses. If the Company is unable to identify the best estimate, the Company records the minimum amount in the range.
	Cash and Cash Equivalents. The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. These investments include, but are not limited to, investments in money market funds, bank deposits, federal government and agency debt securities and commercial paper.
	Investments in Marketable Securities. The Company classifies investments in debt securities that are not considered to be cash equivalents as Short-term investments in marketable securities as discussed in Note 9 – Investments. Short-term investments in marketable securities have a stated maturity of twelve months or less from the balance sheet date. These securities are considered as available for sale and are reported at fair value. Unrealized gains and losses would be recorded net of tax as a component of Accumulated other comprehensive loss in Unrealized investment losses within Shareholders' equity. Declines in market value from the original cost deemed to be "other-than-temporary" are charged to Other income, net, in the period in which the loss occurs. The Company considers both the duration for which a decline in value has occurred and the extent of the decline in its determination of whether a decline in value has been “other than temporary.” Realized gains and losses are calculated based on the specific identification method and are included in Other income, net, in the Consolidated Statement of Operations.
	Restricted Cash. The Company considers the cash deposited in a trust that is pledged as collateral against certain workers' compensation related obligations to be restricted cash. Refer to Note 13 – Commitments and Contingencies for more information.
	Accounts and Notes Receivable and Allowance for Doubtful Accounts. The Company carries its accounts and notes receivable at their face amounts less an allowance for doubtful accounts. On a regular basis, the Company records an allowance for uncollectible receivables based upon known bad debt risks and past loss history, customer payment practices and economic conditions. Actual collection experience may differ from the current estimate of net receivables. A change to the allowance for doubtful accounts may be required if a future event or other change in circumstances results in a change in the estimate of the ultimate collectability of a specific account.
	The Company treats the sale of receivables in which the Company retains an interest as a secured obligation. Accordingly, the short-term portion of the receivables sold that are subject to recourse is recorded in Accounts and notes receivable and Accrued expenses in the Consolidated Balance Sheets.
	Inventories. Inventories are valued at the lower of cost or market, with market based on replacement cost or net realizable value. Approximately 47 percent and 48 percent of the Company's inventories were determined by the first-in, first-out method (FIFO) at December 31, 2014 and December 31, 2013, respectively. Remaining inventories valued at the last-in, first-out method (LIFO), were $122.4 million and $118.0 million lower than the FIFO cost of inventories at December 31, 2014 and 2013, respectively. The Company has reclassified certain prior year work-in-process inventory balances to raw materials to conform to the current period presentation. Additionally, certain prior year LIFO reserves have been reclassified from finished goods to work-in-process and raw materials to reflect a proportional allocation between inventory categories to conform to the current period presentation. Inventory cost includes material, labor and manufacturing overhead. There were no liquidations of LIFO inventory layers in 2014, 2013 or 2012.
	Property. Property, including major improvements and product tooling costs, is recorded at cost. Product tooling costs principally comprise the cost to acquire and construct various long-lived molds, dies and other tooling owned by the Company and used in its manufacturing processes. Design and prototype development costs associated with product tooling are expensed as incurred. Maintenance and repair costs are also expensed as incurred. Depreciation is recorded over the estimated service lives of the related assets, principally using the straight-line method. Buildings and improvements are depreciated over a useful life of five to forty years. Equipment is depreciated over a useful life of two to twenty years. Product tooling costs are amortized over the shorter of the useful life of the tooling or the anticipated life of the applicable product, for a period not to exceed eight years. Gains and losses recognized on the sale and disposal of property are included in either Selling, general and administrative expenses or Restructuring, exit and impairment charges as appropriate. The amount of gains and losses for the years ended December 31 was as follows:
	(in millions)	2014			2013			2012
	Gains on the sale of property	$	1.8		$	5.5		$	5.9
	Losses on the sale and disposal of property	(0.5		)	(0.1		)	(0.7		)
	Net gains on sale and disposal of property	$	1.3		$	5.4		$	5.2
	Software Development Costs. The Company expenses all software development and implementation costs incurred until the Company has determined that the software will result in probable future economic benefit and management has committed to funding the project. Once this is determined, external direct costs of material and services, payroll-related costs of employees working on the project and related interest costs incurred during the application development stage are capitalized. These capitalized costs are amortized over three to seven years. All other related costs, including training costs and costs to re-engineer business processes are expensed as incurred.
	Goodwill and Other Intangibles. Goodwill and other intangible assets primarily result from business acquisitions. The excess of cost over net assets of businesses acquired is recorded as goodwill. The Company reviews these assets for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The reporting units with goodwill balances are the Company's Fitness and Marine Engine segments.
	For 2014, the impairment test for goodwill was a two-step process. The first step compares the fair value of a reporting unit with its carrying amount. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired. If the carrying amount of the reporting unit exceeds its fair value, the second step is performed to measure the amount of the impairment loss, if any. In this second step, the implied fair value of the reporting unit’s goodwill is compared with the carrying amount of the goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess, not to exceed the carrying amount of the goodwill.
	The Company calculates the fair value of its reporting units considering both the income approach and the guideline public company method.  The income approach calculates the fair value of the reporting unit using a discounted cash flow approach utilizing a Gordon Growth model.  Internally forecasted future cash flows, which the Company believes reasonably approximate market participant assumptions, are discounted using a weighted average cost of capital (Discount Rate) developed for each reporting unit.  The Discount Rate is developed using market observable inputs, as well as considering whether or not there is a measure of risk related to the specific reporting unit’s forecasted performance.  Fair value under the guideline public company method is determined by applying market multiples for that reporting unit’s comparable public companies to the unit’s financial results.  The key uncertainties in these calculations are the assumptions used in a reporting unit’s forecasted future performance, including revenue growth and operating margins, as well as the perceived risk associated with those forecasts, and selecting representative market multiples.
	During 2011, the Company early adopted an amendment to the Intangibles - Goodwill and Other topic of the Accounting Standards Codification. The Company determined through its qualitative assessment during 2013 and 2012 that it was not “more likely than not” that the fair values of its reporting units are less than their carrying values. As a result, the Company was not required to perform the two-step impairment test for 2013 or 2012. As part of the qualitative assessment process, the Company calculates the fair value of its reporting units using the income approach as described above. The Company compares the fair value of a reporting unit with its carrying amount to support its qualitative assessment conclusions.
	The fair value of the Company's reporting units was significantly above their carrying values as of December 31, 2014. The Company did not record any goodwill impairments in 2014, 2013 or 2012.
	The Company's primary intangible assets are customer relationships and trade names acquired in business combinations. The costs of amortizable intangible assets are amortized over their expected useful lives, typically between three and fifteen years, using the straight-line method. Intangible assets that are subject to amortization are evaluated for impairment using a process similar to that used to evaluate long-lived assets described below. Intangible assets not subject to amortization are assessed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The impairment test for indefinite-lived intangible assets consists of a comparison of the fair value of the intangible asset with its carrying amount. An impairment loss is recognized for the amount by which the carrying value exceeds the fair value of the asset. The fair value of trade names is measured using a relief-from-royalty approach, which assumes the value of the trade name is the discounted cash flows of the amount that would be paid to third parties had the Company not owned the trade name and instead licensed the trade name from another company. Higher royalty rates are assigned to premium brands within the marketplace based on name recognition and profitability, while other brands receive lower royalty rates. The basis for future cash flow projections is internal revenue forecasts by brand, which the Company believes represent reasonable market participant assumptions, to which the selected royalty rate is applied. These future cash flows are discounted using the applicable Discount Rate, which considers the annual goodwill impairment testing process noted above, as well as any potential risk premium to reflect the inherent risk of holding a standalone intangible asset. The key uncertainties in this calculation are the selection of an appropriate royalty rate and assumptions used in developing internal revenue growth forecasts, as well as the perceived risk associated with those forecasts in developing the Discount Rate.
	The Company did not record any indefinite-lived intangible asset impairments during 2014 and 2013. In 2012, the Company recorded $0.8 million of indefinite-lived intangible asset impairments during the annual impairment testing. An additional $0.7 million of indefinite-lived intangible asset impairment charges were recorded in 2012 for trade names connected with brands experiencing continued weakness in the fiberglass sterndrive boat market segments as well as the refinement of its North American boat product portfolio. Refer to Note 3 – Restructuring Activities for further discussion.
	Equity Investments. For investments in which Brunswick owns or controls from 20 percent to 50 percent of the voting shares, which includes all of Brunswick's unconsolidated joint venture investments, the Company uses the equity method of accounting. The Company's share of net earnings or losses from equity method investments is included in the Consolidated Statements of Operations. The Company accounts for other investments, over which the Company does not have the ability to exercise significant influence, under the cost method of accounting.
	The Company periodically evaluates the carrying value of its investments, and at December 31, 2014 and 2013, such investments were recorded at the lower of cost or fair value. In the fourth quarter of 2014, the Company recorded a $20.2 million impairment charge in order to reflect the fair value of the Company’s equity method investment in Bella-Veneet Oy (Bella), a Finnish boat manufacturer, as discussed in Note 9 – Investments.
	Long-Lived Assets. The Company continually evaluates whether events and circumstances have occurred that indicate the remaining estimated useful lives of its definite-lived intangible assets--excluding goodwill and indefinite-lived trade names--and other long-lived assets may warrant revision or that the remaining balance of such assets may not be recoverable. Once an impairment indicator is identified, the Company tests for recoverability of the related asset group using an estimate of undiscounted cash flows over the remaining asset group's life. If an asset group's carrying value is not recoverable, the Company records an impairment loss based on the excess of the carrying value of the asset group over the long-lived asset group's fair value. Fair value is determined using observable inputs, including the use of appraisals from independent third parties, when available, and, when observable inputs are not available, based on the Company's assumptions of the data that market participants would use in pricing the asset, based on the best information available in the circumstances. Specifically, the Company uses discounted cash flows to determine the fair value of the asset when observable inputs are unavailable. The Company tested its long-lived asset balances for impairment as indicators presented themselves during 2014, 2013 or 2012, resulting in impairment charges of $1.5 million, $7.1 million and $11.4 million, respectively, which are recognized in Restructuring, exit and impairment charges and Selling, general and administrative expense in the Consolidated Statements of Operations.
	Other Long-Term Assets. Other long-term assets are mainly long-term receivables originated by the Company and assigned to third parties, deferred debt issuance costs and other long-term notes receivable. As of December 31, 2014 and 2013, amounts assigned to third parties totaled $19.6 million and $18.9 million, respectively. The assignment of these instruments does not meet sale criteria as a result of the Company's contingent obligation to repurchase the receivables in the event of customer non-payment and therefore is treated as a secured obligation. Accordingly, these amounts were recorded in the Consolidated Balance Sheets under Other long-term assets and Long-term liabilities – Other. Fees and expenses related to acquiring the Company's debt are capitalized and then amortized over the life of the corresponding debt. As of December 31, 2014 and 2013, deferred debt issuance costs were $7.3 million and $6.6 million, respectively.
	Revenue Recognition. Brunswick's revenue is derived primarily from the sale of boats, marine engines, marine parts and accessories, fitness equipment and billiards tables. Revenue is recognized in accordance with the terms of the sale, primarily upon shipment to customers, once the sales price is fixed or determinable and collectability is reasonably assured. Brunswick offers discounts and sales incentives that include retail promotions, rebates and manufacturer coupons that are recorded as reductions of revenues in Net sales in the Consolidated Statements of Operations. The estimated liability and reduction in revenue for sales incentives is recorded at the later of when the program has been communicated to the customer or at the time of sale. Revenues from freight are included as a part of Net sales in the Consolidated Statements of Operations, whereas shipping, freight and handling costs are included in Cost of sales.
	Advertising Costs. The Company records advertising and promotion costs in Selling, general and administrative expense in the Consolidated Statements of Operations in the period when the advertising first takes place. Advertising and promotion costs were $31.2 million, $30.6 million and $30.9 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Foreign Currency. The functional currency for the majority of Brunswick's operations is the U.S. dollar. All assets and liabilities of operations with a functional currency other than the U.S. dollar are translated at period end current rates. The resulting translation adjustments are recorded in Accumulated other comprehensive income (loss), net of tax. Revenues and expenses of operations with a functional currency other than the U.S. dollar are translated at the average exchange rates for the period.
	Other Comprehensive Income (Loss). Accumulated other comprehensive loss includes prior service costs and credits and net actuarial gains and losses for defined benefit plans, currency translation adjustments and unrealized derivative and investment gains and losses, all net of tax. The net effect of these items reduced Shareholders' equity on a cumulative basis by $480.5 million and $401.5 million as of December 31, 2014 and 2013, respectively. The change from 2013 to 2014 was primarily due to changes in Net actuarial losses related to unfavorable adjustments to defined benefit plan liabilities resulting from decreases in the discount rate and changes to assumptions regarding mortality, partially offset by better than expected return on plan assets, the amortization of net actuarial losses and the impact of lump sum payout actions during 2014. Additionally, the strengthening of the U.S. dollar against foreign currencies resulted in unfavorable currency translation adjustments.
	Stock-Based Compensation. The Company records amounts for all share-based payments to employees, including grants of stock options and the compensatory elements of employee stock purchase plans over the vesting period in the income statement based upon their fair values at the date of the grant. Share-based employee compensation costs are recognized as a component of Selling, general and administrative expense in the Consolidated Statements of Operations. See Note 18 – Stock Plans and Management Compensation for a description of the Company's accounting for stock-based compensation plans.
	Derivatives. The Company uses derivative financial instruments to manage its risk associated with movements in foreign currency exchange rates, interest rates and commodity prices. These instruments are used in accordance with guidelines established by the Company's management and are not used for trading or speculative purposes. All derivatives are recorded on the Consolidated Balance Sheets at fair value. See Note 14 – Financial Instruments for further discussion.
	Recent Accounting Pronouncements.  The Company evaluates the pronouncements of various authoritative accounting organizations, primarily the Financial Accounting Standards Board (FASB), the SEC, and the Emerging Issues Task Force, to determine the impact of new pronouncements on GAAP and the impact on the Company.  The following are recent accounting pronouncements that have been adopted during 2014, or will be adopted in future periods.
	Going Concern: In August 2014, the FASB amended the Accounting Standards Codification (ASC) to provide guidance on determining when and how an entity must disclose going concern uncertainties in its financial statements. The amendment requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date of issuance of an entity's financial statements. If there is substantial doubt about the entity's ability to continue as a going concern, an entity must provide certain footnote disclosures. The amendment is effective for fiscal years, and the interim periods thereafter, beginning after December 15, 2016, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material effect on the Company's consolidated financial statements.
	Revenue Recognition: In May 2014, the FASB and International Accounting Standards Board jointly issued a final standard on revenue recognition which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This standard will supersede most current revenue recognition guidance. Under the new standard, entities are required to identify the contract with a customer; identify the separate performance obligations in the contract; determine the transaction price; allocate the transaction price to the separate performance obligations in the contract; and recognize the appropriate amount of revenue when (or as) the entity satisfies each performance obligation. The standard is effective for fiscal years, and the interim periods within those years, beginning on or after January 1, 2017. Entities have the option of using either retrospective transition or a modified approach in applying the new standard. The Company is currently evaluating the approach it will use to apply the new standard and the impact that the adoption of the new standard will have on the Company’s consolidated financial statements.
	Discontinued Operations: In April 2014, the FASB amended the ASC to raise the threshold for a disposal to qualify as a discontinued operation. Under the new guidance, a discontinued operation represents a strategic shift that has or will have a major effect on an entity's operations and financial results. The guidance also expands the disclosures for discontinued operations, including new disclosures related to individually material disposals that do not meet the definition of a discontinued operation. The amendment is effective for fiscal years, and the interim periods within those years, beginning after December 15, 2014, with early adoption permitted only for disposals that have not been reported in financial statements previously issued. The Company did not early adopt this ASC amendment and is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material effect on the Company's consolidated financial statements.
	Unrecognized Tax Benefit: In July 2013, the FASB amended the ASC to provide guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss (NOL) carryforward, a similar tax loss, or a tax credit carryforward exists. The guidance states that entities should present an unrecognized tax benefit as a reduction of a deferred tax asset for an NOL or tax credit carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. The amendment is effective for fiscal years, and the interim periods within those years, beginning after December 15, 2013, with early adoption permitted. The Company adopted this amendment in 2014 and it did not have a material impact on the Company’s consolidated results of operations and financial condition.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Note 2 – Discontinued Operations
	On July 17, 2014, the Company entered into an agreement to sell its retail bowling business to AMF Bowling Centers, Inc. In connection with its decision to sell its bowling centers, the Company also announced its intention to divest its bowling products business. On December 31, 2012, the Board of Directors authorized the Company to exit its Hatteras and Cabo boat businesses. As a result of these actions, these businesses, which were previously recorded in the Company's former Bowling & Billiards segment and the Boat segment, respectively, are being reported as discontinued operations in the Consolidated Statements of Operations for all periods presented. The Company does not have or anticipate having any significant continuing involvement or continuing cash flows associated with these businesses. The assets and liabilities of these businesses met the accounting criteria to be classified as held for sale and have been aggregated and reported on separate lines of the Consolidated Balance Sheets for all periods presented.
	On September 18, 2014, the Company completed the sale of its retail bowling business to AMF Bowling Centers, Inc. as well as, in separate transactions, completed the sale of two retail bowling centers in California. The sales resulted in net cash proceeds of $264.3 million and an after-tax gain of $52.6 million. In connection with the sale of its retail bowling business, the Company entered into a trademark licensing agreement allowing AMF Bowling Centers, Inc. to use the Company's bowling retail related trademarks and trade names over a five year period from the date of acquisition. As a result, the Company recorded deferred income of $20.7 million related to this agreement, which will be recognized as Other income in the Consolidated Statements of Operations over five years. In connection with the sale of its retail bowling business, the Company has retained certain liabilities and provided guarantees on certain leased bowling centers.
	In August 2013, the Company completed the sale of its Hatteras and Cabo boat businesses resulting in an after-tax gain of $1.6 million.

Restructuring and Related Activities [Abstract]
Restructuring Activities	Note 3 – Restructuring Activities
	Brunswick has announced and implemented a number of restructuring initiatives designed to improve the Company’s cost structure, better utilize overall capacity and improve general operating efficiencies.  These initiatives reflected the Company’s response to the significant reduction in the marine market and resulted in the recognition of restructuring, exit and impairment charges in the Consolidated Statements of Operations during 2014, 2013 and 2012.
	The costs incurred under these initiatives include:
	Restructuring Activities – These amounts mainly relate to:
	•	Employee termination and other benefits
	•	Costs to retain and relocate employees
	•	Consulting costs
	•	Consolidation of manufacturing footprint
	Exit Activities – These amounts mainly relate to:
	•	Employee termination and other benefits
	•	Lease exit costs
	•	Inventory write-downs
	•	Facility shutdown costs
	Asset Disposition Actions – These amounts mainly relate to sales of assets and impairments of:
	•	Fixed assets
	•	Tooling
	•	Patents and proprietary technology
	•	Dealer networks
	•	Trade names
	Impairments of definite-lived assets are recognized when, as a result of the restructuring activities initiated, the carrying amount of the long-lived asset is not expected to be fully recoverable.  The impairments recognized were equal to the difference between the carrying amount of the asset and the estimated fair value of the asset, which was determined using observable inputs, including appraisals from independent third parties when available, and, when observable inputs were not available, was determined using the Company’s assumptions, including the data that market participants would use in pricing the asset, based on the best information available in the circumstances.  Specifically, the Company used discounted cash flows to determine the fair value of the asset when observable inputs were unavailable.
	Intangible assets not subject to amortization are assessed for impairment at least annually and whenever events or changes in circumstances, such as announcements of restructuring activities, indicate that the carrying value may not be recoverable. The impairment test for indefinite-lived intangible assets consists of a comparison of the fair value of the intangible asset with its carrying amount. An impairment loss is recognized for the amount by which the carrying value exceeds the fair value of the asset. The fair value of trade names is measured using a relief-from-royalty approach, which assumes the value of the trade name is the discounted cash flows of the amount that would be paid to third parties had the Company not owned the trade name and instead licensed the trade name from another company.
	The Company has reported restructuring and exit activities based on the specific driver of the cost and reflected the expense in the accounting period when the cost has been committed to or incurred, as appropriate. The following table is a summary of the net expense associated with the restructuring, exit and impairment activities for 2014, 2013 and 2012.  The 2014 charges consist of expenses related to actions initiated in 2014, 2013, 2012, 2010 and 2009. The 2013 charges consist of expenses related to actions initiated in 2013, 2012 and 2009. The 2012 charges consist of expenses related to actions initiated in 2012, 2011, 2010 and 2009.

	Actions Initiated in 2013
	In the fourth quarter of 2013, the Company made the decision to outsource woodworking operations for its yachts and sport yachts, which resulted in long-lived asset impairment charges. The Company announced in the first quarter of 2013 the consolidation of its yacht and motoryacht production at its Palm Coast, Florida manufacturing plant. As a result, the Company suspended manufacturing at its Sykes Creek boat manufacturing facility in nearby Merritt Island, Florida at the end of June 2013. The Company recorded restructuring, exit and impairment charges in 2014 and 2013 related to these actions.

Actions Initiated in 2012
The Company recorded restructuring and impairment charges in 2012 relating to actions initiated in connection with the continued weakness in the fiberglass sterndrive boat market segments as well as the refinement of its North American boat product portfolio. In 2012, the Company decided to exit Bayliner cruisers in the U.S. and European markets and to further reduce the Company's manufacturing footprint by closing its Knoxville, Tennessee production facility and consolidate its fiberglass cruiser manufacturing into other boat production facilities. Long-lived asset impairment charges were also recorded in the third quarter of 2012 for certain European and Asia-Pacific boat brands as a result of weak powerboat demand in these regions.

Actions Initiated Before 2012
The Company recorded impairment charges in 2009 and 2010 relating to actions to divest non-strategic assets in its Boat segment. In 2014, the Company recorded gains on disposal relating to the third quarter sale of the Company's Riverview plant in Knoxville, Tennessee, that was part of the Company's 2009 restructuring initiatives as well as the second quarter sale of a boat facility in Ashland City, Tennessee, that was part of the Company's 2010 restructuring initiatives.
In 2013 and 2012, the Company continued its restructuring activities initiated before 2012, including consolidating manufacturing operations, reducing the Company's global workforce, disposing of non-strategic assets and selling previously closed facilities. These actions were designed to provide long-term cost savings by reducing the Company's fixed-cost structure.
During the third quarter of 2009, the Company announced plans to reduce excess manufacturing capacity by relocating inboard and sterndrive production to Fond du Lac, Wisconsin and closing its Stillwater, Oklahoma plant.  This plant transition was completed in the second quarter of 2012.

Business Combinations [Abstract]
Acquisitions	Note 4 – Acquisitions
	On July 31, 2014, the Company acquired 100 percent of privately held Bell Industries Recreational Products Group, Inc. (Bell), which is based in Eagan, Minnesota. Bell is a distributor of parts and accessories to the marine, recreational vehicle and powersports markets, serving primarily the Upper Midwest of the U.S. The Company believes this acquisition will allow the Company to solidify its footprint in the Upper Midwest with locations in Minnesota, Michigan and Wisconsin, enhance its growth of its parts and accessories businesses, expand the depth and breadth of its product portfolio and enable entry into attractive adjacent markets. Bell is managed as part of the Company’s marine service, parts and accessories businesses within the Marine Engine segment.
	The net cash consideration paid by the Company to acquire Bell was $11.9 million. The assets acquired and liabilities assumed in the Bell acquisition have been measured at their fair values at the acquisition date, resulting in $2.0 million of identifiable intangible assets for customer relationships and $0.9 million of goodwill, which are both deductible for tax purposes. The amounts assigned to Bell's customer relationships will be amortized over the estimated useful life of 8 years.
	On June 16, 2014, the Company acquired 100 percent of privately held Whale, which is based in Bangor, Northern Ireland, and is a manufacturer of water movement and heating systems for the marine, recreational vehicle, industrial and other markets. The Company believes this acquisition will allow the Company to more fully compete across a number of parts and accessories product categories, enable entry into attractive adjacent markets and expand the global presence of the marine service, parts and accessories businesses. Whale is managed as part of the Company's marine service, parts and accessories businesses within the Marine Engine segment.
	The net cash consideration paid by the Company to acquire Whale was $29.6 million, which included payments of $10.0 million to retire acquiree debt. The assets acquired and liabilities assumed in the Whale acquisition have been measured at their fair values at the acquisition date, resulting in $11.9 million of identifiable intangible assets, including customer relationships, trade names and patents and proprietary technology for $6.1 million, $3.7 million and $2.1 million, respectively, and $7.9 million of goodwill, all of which are not deductible for tax purposes. The Company considers its trade names to be indefinite-lived intangible assets, whereas the amounts assigned to Whale's customer relationships and patent and proprietary technology will be amortized over the estimated useful lives of 14 years and 5 years, respectively.
	These acquisitions were not and would not have been material to the Company's net sales, results of operations or total assets during the years ended December 31, 2014, December 31, 2013 and December 31, 2012, respectively. Accordingly, the Company's consolidated results from operations do not differ materially from historical performance as a result of these acquisitions, and therefore, pro-forma results are not presented.

Earnings Per Share [Abstract]
Earnings (Loss) per Common Share	Note 5 – Earnings (Loss) per Common Share
	Basic earnings (loss) per common share is calculated by dividing Net earnings (loss) by the weighted average number of common shares outstanding during the period.  Diluted earnings (loss) per common share is calculated similarly, except that the calculation includes the dilutive effect of stock-settled SARs and stock options (collectively “options”), non-vested stock awards and performance awards.
	Basic and diluted earnings (loss) per common share for the years ended December 31, 2014, 2013 and 2012 were calculated as follows:
	(in millions, except per share data)	2014		2013		2012
	Net earnings from continuing operations	$	194.9	$	756.8	$	124.6
	Net earnings (loss) from discontinued operations, net of tax	50.8		12.4		(74.6		)
	Net earnings	$	245.7	$	769.2	$	50
	Weighted average outstanding shares – basic	93.6		91.2		89.8
	Dilutive effect of common stock equivalents	1.5		2.6		2.6
	Weighted average outstanding shares – diluted	95.1		93.8		92.4
	Basic earnings (loss) per common share:
	Continuing operations	$	2.08	$	8.3	$	1.39
	Discontinued operations	0.55		0.13		(0.83		)
	Net earnings	$	2.63	$	8.43	$	0.56
	Diluted earnings (loss) per common share:
	Continuing operations	$	2.05	$	8.07	$	1.35
	Discontinued operations	0.53		0.13		(0.81		)
	Net earnings	$	2.58	$	8.2	$	0.54
	As of December 31, 2014, the Company had 2.7 million options outstanding, of which 2.3 million were exercisable.  This compares with 3.8 million and 8.2 million options outstanding, of which 2.6 million and 5.5 million were exercisable, as of December 31, 2013 and December 31, 2012, respectively.  During the year ended December 31, 2014, there were 0.2 million average shares of options outstanding for which the exercise price was greater than the average market price of the Company’s shares for the period then ended.  These options were not included in the computation of diluted earnings per common share because the effect would have been anti-dilutive. This compares to 0.9 million and 2.2 million anti-dilutive shares of options outstanding that were excluded from the corresponding periods ended December 31, 2013 and December 31, 2012, respectively. Changes in average outstanding basic shares from 2012 to 2014 reflect the impact of options exercised and the vesting of stock and performance awards since the beginning of 2012.

Segment Reporting [Abstract]
Segment Data	Note 6 – Segment Information
	Brunswick is a manufacturer and marketer of leading consumer brands and has three operating and reportable segments: Marine Engine, Boat and Fitness.  The Company’s segments are defined by management’s reporting structure and operating activities.
	As discussed in Note 2 – Discontinued Operations, during the third quarter of 2014, the Company began reporting its retail bowling and bowling products businesses as discontinued operations. These businesses were previously reported in the former Bowling & Billiards segment. Additionally, the results of the billiards business are being reported in the Company's Fitness segment for all periods presented. During the fourth quarter of 2012, Brunswick began reporting its Hatteras and Cabo boat businesses as discontinued operations. These businesses were previously reported in the Boat segment. Segment results have been restated for all periods presented to reflect these changes.
	The Marine Engine segment manufactures and markets a full range of outboard engines, sterndrive engines, inboard engines and marine parts and accessories, which are principally sold directly to boat builders, including Brunswick's Boat segment, or through marine retail dealers and distributors worldwide. The Company's engine manufacturing plants are located mainly in the United States, China and Japan, with sales mainly to markets in the Americas, Europe and Asia.
	The Boat segment designs, manufactures and markets fiberglass pleasure boats, offshore fishing boats, yachts and sport yachts, aluminum fishing boats, pontoon boats, deck boats and inflatable boats, which are sold primarily through dealers. The Boat segment's products are manufactured mainly in the United States, Europe, Mexico and South America. Sales to the segment's largest boat dealer, MarineMax, which has multiple locations, comprised approximately 18 percent, 17 percent and 16 percent of Boat segment sales in 2014, 2013 and 2012, respectively.
	The Fitness segment designs, manufactures and markets fitness equipment, including treadmills, total body cross-trainers, stair climbers, stationary bikes and strength-training equipment as well as billiards tables and accessories. These products are manufactured mainly in the United States and Hungary or are sourced from international suppliers. Fitness equipment is sold mainly in the Americas, Europe and Asia to health club, corporate, university, hospitality, military and government facilities, and to consumers through selected mass merchants, specialty retail dealers and through the Company's Web site. Consumer billiards equipment is predominantly sold in the United States and distributed primarily through dealers.
	The Company evaluates performance based on business segment operating earnings.  Operating earnings of segments do not include the expenses of corporate administration, non-service related pension costs, pension lump sum payout settlement charges, impairments of equity method investments, earnings from unconsolidated equity affiliates, other expenses and income of a non-operating nature, interest expense and income, loss on early extinguishment of debt or provisions for income taxes. As a result of freezing benefit accruals in its defined benefit pension plans, the Company allocates only service-related costs to the operating segment results and reports all other components of pension expense such as Interest cost, Expected return on plan assets, Amortization of net actuarial losses and lump sum settlement charges in Pension - non-service costs. Pension costs associated with Service cost and Amortization of prior service cost, while not significant, remain in the reporting segments as presented in the tables below.
	Corporate/Other results include items such as corporate staff and administrative costs.  Corporate/Other total assets consist of mainly cash, cash equivalents and investments in marketable securities, restricted cash, income tax balances and investments in unconsolidated affiliates.  Marine eliminations adjust for sales between the Marine Engine and Boat segments, primarily for the sale of engines and parts and accessories to various boat brands, which are consummated at established arm’s length transfer prices as the intersegment pricing for these engines and parts and accessories are based upon and consistent with selling prices to the Company's third party customers.
	Information as to the operations of Brunswick's operating segments is set forth below:

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 7 – Fair Value Measurements
	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.  Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.  There is a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable.
	•	Level 1 - Quoted prices in active markets for identical assets or liabilities.  These are typically obtained from real-time quotes for transactions in active exchange markets involving identical assets or liabilities.
	•	Level 2 - Inputs, other than quoted prices included within Level 1, which are observable for the asset or liability, either directly or indirectly.  These are typically obtained from readily available pricing sources for comparable instruments.
	•	Level 3 - Unobservable inputs, where there is little or no market activity for the asset or liability.  These inputs reflect the reporting entity’s own assumptions of the data that market participants would use in pricing the asset or liability, based on the best information available in the circumstances.
	The following table summarizes Brunswick’s financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2014:
	(in millions)	Level 1		Level 2		Level 3		Total

	Refer to Note 14 – Financial Instruments for additional information related to the fair value of derivative assets and liabilities by class. Other liabilities shown in the tables above include certain deferred compensation plans of the Company. In addition to the items shown in the tables above, see Note 17 – Postretirement Benefits for further discussion regarding the fair value measurements associated with the Company’s postretirement benefit plans.
	As discussed in Note 3 – Restructuring Activities, the Company has initiated various restructuring activities requiring the Company to perform fair value measurements, on a non-recurring basis, of certain asset groups to test for potential impairments.  Certain of these fair value measurements indicated that the asset groups were impaired and, therefore, the assets were written down to fair value.  Once an asset has been impaired, it is not remeasured at fair value on a recurring basis; however, it is still subject to fair value measurements to test for recoverability of the carrying amount.

Receivables [Abstract]
Financing Receivables	Note 8 – Financing Receivables
	The Company has recorded financing receivables, which are defined as a contractual right to receive money, as assets on its Consolidated Balance Sheets as of December 31, 2014 and 2013.  Substantially all of the Company’s financing receivables are for commercial customers.  The Company classifies its financing receivables into three categories: receivables repurchased under recourse provisions (Recourse Receivables); receivables sold to third-party finance companies (Third-Party Receivables) and customer notes and other (Other Receivables).  Recourse Receivables are the result of the contingent recourse arrangements discussed in Note 13 – Commitments and Contingencies.  Third-Party Receivables are accounts that have been sold to third-party finance companies, but do not meet the definition of a true sale, and are therefore recorded as an asset with an offsetting balance recorded as a secured obligation in Accrued expenses and Other long-term liabilities as discussed in Note 1 – Significant Accounting Policies.  Other Receivables are mostly comprised of notes from customers, which are originated by the Company in the normal course of business.  Financing receivables are carried at their face amounts less an allowance for doubtful accounts.
	The Company sells a broad range of recreational products to a worldwide customer base and extends credit to its customers based upon an ongoing credit evaluation program.  The Company’s business units maintain credit organizations to manage financial exposure and perform credit risk assessments on an individual account basis.  Accounts are not aggregated into categories for credit risk determinations.  Due to the composition of the account portfolio, the Company does not believe that the credit risk posed by the Company’s financing receivables is significant to its operations, financial condition or cash flows.  There were no significant troubled debt restructurings during the years ended December 31, 2014 and 2013.
	The following are the Company’s financing receivables, excluding trade accounts receivable contractually due within one year, by segment as of December 31, 2014:

Investments	Note 9 – Investments
	Investments in Marketable Securities
	The Company invests a portion of its cash reserves in marketable debt securities.  These investments are reported in Short-term investments in marketable securities on the Consolidated Balance Sheets. Furthermore, the debt securities have readily determinable market values and are being accounted for as available-for-sale investments.  These investments are recorded at fair value with unrealized gains and losses reflected in Accumulated other comprehensive loss, a component of Shareholders’ equity on the Company’s Consolidated Balance Sheets, on an after-tax basis.
	The following is a summary of the Company’s available-for-sale securities, all due in one year or less, as of December 31, 2014:

	U.S. Treasury Bills	0.8		—		—		0.8
	Total available-for-sale securities	$	12.7	$	—	$	—	$	12.7
	The Company had $11.9 million in redemptions of available-for-sale securities during 2014. The Company had $116.9 million in redemptions and $35.7 million in sales of available-for-sale securities during 2013. During the second quarter of 2013, proceeds from the redemptions and sales of available-for-sale securities were used to repurchase outstanding Senior notes due in 2016. Refer to Note 16 – Debt for more information.
	At each reporting date, management reviews the debt securities to determine if any loss in the value of a security below its amortized cost should be considered “other-than-temporary.”  For the evaluation, management determines whether it intends to sell, or if it is more likely than not that it will be required to sell, the securities. This determination considers current and forecasted liquidity requirements, regulatory and capital requirements and the strategy for managing the Company’s securities portfolio. For all impaired debt securities for which there was no intent or expected requirement to sell, the evaluation considers all available evidence to assess whether it is likely the amortized cost value will be recovered. The Company also considers the nature of the securities, the credit rating or financial condition of the issuer, the extent and duration of the unrealized loss and market conditions.  As of December 31, 2014, there were no unrealized losses related to debt securities that required management evaluation.
	Equity Investments
	The Company has certain unconsolidated international and domestic affiliates that are accounted for using the equity method. The equity method is applied in situations where the Company has the ability to exercise significant influence, but not control, over the investees. Management reviews equity investments for impairment whenever indicators are present suggesting that the carrying value of an investment is not recoverable. The following items are examples of impairment indicators: significant, sustained declines in an investee’s revenue, earnings, and cash flow trends; adverse market conditions of the investee’s industry or geographic area; the investee’s inability to execute its operating plan; the investee’s ability to continue operations measured by several items, including liquidity; and other factors. Once an impairment indicator is identified, management uses considerable judgment to determine if the decline in value is other than temporary, in which case the equity investment is written down to its estimated fair value, which could significantly adversely impact reported results of operations.
	In the fourth quarter of 2014, the Company determined that the fair value of its 36 percent investment in Bella-Veneet Oy (Bella), a Finnish boat manufacturer, had declined significantly as a result of the inability of the business to achieve profitability due to weak market conditions for its products, which has led to significant declines in revenue. The Company calculates fair value using the income approach described in the Goodwill and Other Intangibles section of Note 1 – Significant Accounting Policies. As a result of performing its analysis, the Company determined that the book value of its investment exceeded its fair value and concluded that this decline in value was other than temporary. The Company recorded a $20.2 million charge during the fourth quarter of 2014 in order to reflect the fair value of the Company’s investment in Bella of $1.1 million. This charge is reported as Impairment of equity method investment in the Consolidated Statements of Operations. Management performed similar analyses in 2013 and 2012 and concluded that no impairment adjustments were required.
	Refer to Note 10 – Financial Services for more details on the Company’s Brunswick Acceptance Company, LLC joint venture. The Company contributed $0.9 million and $0.8 million in 2014 and 2013, respectively, to fund a part ownership of Mercury Finance, a joint venture between Brunswick's Mercury Marine division and Allied Credit, an Australian-based finance company. The Company did not make any contributions to its other joint ventures in 2012.
	Brunswick did not receive any dividends from its unconsolidated affiliates in 2014 or 2012, but did receive $0.3 million of dividends in the year ended December 31, 2013.
	The Company's sales to and purchases from its equity investments, along with the corresponding receivables and payables, were not material to the Company's overall results of operations for the years ended December 31, 2014, 2013, and 2012, or its financial position as of December 31, 2014 and 2013.
	In December 2011, the Company announced plans to dissolve the Cummins MerCruiser Diesel Marine LLC joint venture between Brunswick's Mercury Marine division and Cummins Marine, a division of Cummins Inc. During the second quarter of 2012, the joint venture ceased operations and began the liquidation process as the joint venture's business activities were transitioned to the parent companies. The liquidation process was completed in 2013.

Financial Services [Abstract]
Financial Services	Note 10 – Financial Services
	The Company, through its Brunswick Financial Services Corporation (BFS) subsidiary, owns a 49 percent interest in a joint venture, Brunswick Acceptance Company, LLC (BAC).  CDF Ventures, LLC (CDFV), a subsidiary of GE Capital Corporation (GECC), owns the remaining 51 percent.  BAC commenced operations in 2003 and provides secured wholesale inventory floor-plan financing to Brunswick’s boat and engine dealers.
	In March 2013, the term of the BAC joint venture was extended through December 31, 2016.  The joint venture agreement contains provisions allowing for the renewal of the agreement or the purchase of the other party’s interest in the joint venture at the end of its term.  Alternatively, either partner may terminate the agreement at the end of its term.  In June 2014, the joint venture agreement was amended to adjust a financial covenant that was conformed to the maximum leverage ratio test contained in the Facility as described in Note 16 – Debt. As of December 31, 2014, the Company was in compliance with the leverage ratio covenant under both the joint venture agreement and the Facility as described in Note 16 – Debt.
	BAC is funded in part through a $1.0 billion secured borrowing facility from GE Commercial Distribution Finance Corporation (GECDF), which is in place through the term of the joint venture, and with equity contributions from both partners.  BAC also sells a portion of its receivables to a securitization facility, the GE Dealer Floorplan Master Note Trust, which is arranged by GECC.  The sales of these receivables meet the requirements of a “true sale” and are therefore not retained on the financial statements of BAC.  The indebtedness of BAC is not guaranteed by the Company or any of its subsidiaries.  In addition, BAC is not responsible for any continuing servicing costs or obligations with respect to the securitized receivables.  Through June 28, 2014, BFS and GECDF had an income sharing arrangement related to income generated from the receivables sold by BAC to the securitization facility.  The Company recorded this income in Other income, net, in the Consolidated Statements of Operations. Beginning July 1, 2014, BAC began recognizing all income related to securitized receivables at the time of sale to conform with a change in the structure of the securitization facility. The income sharing arrangement remained in place through December 31, 2014 for assets securitized prior to July 1, 2014.
	The Company considers BFS’s investment in BAC as an investment in a variable interest entity of which the Company is not the primary beneficiary.  To be considered the primary beneficiary, the Company must have the power to direct the activities of BAC that most significantly impact BAC’s economic performance and the Company must have the obligation to absorb losses or the right to receive benefits from BAC that could be potentially significant to BAC.  Based on a qualitative analysis performed by the Company, BFS did not meet the definition of a primary beneficiary.  As a result, BFS’s investment in BAC is accounted for by the Company under the equity method and is recorded as a component of Equity investments in its Consolidated Balance Sheets.  The Company records BFS’s share of income or loss in BAC based on its ownership percentage in the joint venture in Equity earnings (loss) in its Consolidated Statements of Operations.  BFS’s equity investment is adjusted monthly to maintain a 49 percent interest in accordance with the capital provisions of the joint venture agreement.  The Company funds its investment in BAC through cash contributions and reinvested earnings.  BFS’s total investment in BAC at December 31, 2014 and December 31, 2013 was $10.8 million and $11.2 million, respectively.
	The Company’s maximum loss exposure relating to BAC is detailed as follows:
	(in millions)	December 31,			December 31,
		2014			2013
	Investment	$	10.8		$	11.2
	Repurchase and recourse obligations (A)	37.3			37
	Liabilities (B)	(1.6		)	(1.4		)
	Total maximum loss exposure	$	46.5		$	46.8
	(A)	Repurchase and recourse obligations are off-balance sheet obligations provided by the Company for the Boat and Marine Engine segments, respectively, and are included within the Maximum Potential Obligations disclosed in Note 13 – Commitments and Contingencies.  Repurchase and recourse obligations are mainly related to a North American repurchase agreement with GECDF and could be reduced by repurchase activity occurring under other similar agreements with GECDF and affiliates.  The Company’s risk under these repurchase arrangements is partially mitigated by the value of the products repurchased as part of the transaction.  Amounts above exclude any potential recoveries from the value of the repurchased product. The previously reported amount of $51.8 million as of December 31, 2013, reflects repurchase and recourse obligations under the Company's global repurchase agreement that was replaced in 2013 with the North American repurchase agreement described above.
	(B)	Represents accrued amounts for potential losses related to recourse exposure and the Company’s expected losses on obligations to repurchase products, after giving effect to proceeds anticipated to be received from the resale of these products to alternative dealers.
	BFS recorded income related to the operations of BAC of $6.0 million, $3.7 million and $3.6 million for the years ended December 31, 2014, 2013 and 2012, respectively. This income includes amounts earned by BFS under the aforementioned income sharing agreement.

	Beginning in the third quarter of 2008, the Company maintained a full valuation allowance against certain deferred tax assets for federal and the majority of its state and foreign jurisdictions, having determined it was more likely than not that the deferred tax assets would not be realized. The determination of recording and releasing valuation allowances against deferred tax assets is made, in part, pursuant to the Company's assessment as to whether it is more likely than not that the Company will generate sufficient future taxable income against which benefits of the deferred tax assets may or may not be realized. Significant judgment is required in making estimates regarding the Company’s ability to generate income in future periods. The Company continued to maintain valuation allowances through the third quarter of 2013 as there was insufficient positive evidence to overcome the substantial negative evidence of cumulative losses in periods preceding 2013.
	In the fourth quarter of 2013, the Company reached the conclusion that it was appropriate to release valuation allowance reserves against a significant portion of its federal deferred tax assets and against certain state deferred tax assets due to the sustained positive operating performance of its U.S. operations and the expectation of future taxable income. Additionally, the Company achieved a cumulative three year income position domestically, reached four consecutive quarters of positive pre-tax operating earnings, and completed its near- and mid-term business plans, all of which were significant positive factors that overcame substantive prior negative evidence. The Company also considered forecasts of future operating results and utilization of net operating losses and tax credits prior to their expiration. Reversal of deferred tax asset valuation allowances also were recorded in the fourth quarter of 2013 for business units located in Norway and Sweden. As a result, the Company recorded a $599.5 million reversal of its deferred tax asset valuation allowance reserves in the fourth quarter of 2013 after determining it was more likely than not that certain deferred tax assets would be realized. The Company's remaining valuation allowance reserves at December 31, 2013 in the U.S. primarily related to capital loss carryforwards, non-amortizable intangibles, and various state operating loss carryforwards and state tax credits that are subject to rules which may limit future utilization, as well as for certain foreign jurisdictions, including Brazil, Portugal and Spain.
	During the third quarter of 2014, the Company completed the sale of its retail bowling business. This transaction is expected to generate capital gains for tax purposes allowing the Company to utilize all of its capital loss carryforwards. Therefore, during the third quarter of 2014, the Company recorded a $9.5 million reversal of its deferred tax asset valuation allowance reserves related to capital loss carryforwards, which has been reflected as a tax benefit reported in Note 2 – Discontinued Operations.
	At December 31, 2014, the Company had a total valuation allowance against its deferred tax assets of $69.0 million, of which $10.6 million was classified as current and $58.4 million as non-current. The remaining realizable value of deferred tax assets at December 31, 2014 was determined by evaluating the potential to recover the value of these assets through the utilization of tax loss and credit carrybacks, the reversal of existing taxable temporary differences, certain tax planning strategies and future taxable income exclusive of reversing temporary differences and carryforwards. At December 31, 2014, the Company retained valuation allowance reserves of $59.5 million against deferred tax assets in the U.S. primarily related to non-amortizable intangibles and various state operating loss carryforwards and state tax credits that are subject to restrictive rules for future utilization, and valuation allowances of about $9.5 million for deferred tax assets related to foreign jurisdictions, primarily for Brazil and Portugal.
	At December 31, 2014, the tax benefit of loss carryovers totaling $72.1 million were available to reduce future tax liabilities. This deferred tax asset was comprised of $59.9 million for the tax benefit of state net operating loss (NOL) carryforwards and, $12.2 million for the tax benefit of foreign NOL carryforwards. NOL carryforwards of $63.4 million expire at various intervals between the years 2015 and 2033, while $8.7 million have an unlimited life.
	At December 31, 2014, tax credit carryforwards totaling $95.7 million were available to reduce future tax liabilities. This deferred tax asset was comprised of $63.6 million related to general business credits and other miscellaneous federal credits, and $32.1 million of various state tax credits related to research and development, capital investment and job incentives. The above credits expire at various intervals between the years 2015 and 2034.
	The Company has historically provided deferred taxes for the presumed ultimate repatriation to the U.S. of earnings from most of its non-U.S. subsidiaries and unconsolidated affiliates. As of December 31, 2013, the indefinite reversal criterion had been applied to certain entities and allowed the Company to overcome that presumption to the extent the earnings were to be indefinitely reinvested outside the United States. As of January 1, 2014, the Company determined that the indefinite reinvestment assertion should be applied to certain additional non-U.S. subsidiaries' earnings for only 2014 and future years which will be considered indefinitely reinvested. Accordingly, no deferred income taxes have been provided as of December 31, 2014 on the applicable undistributed earnings of the non-U.S. subsidiaries where the indefinite reinvestment assertion has been applied. The Company had undistributed earnings of foreign subsidiaries of $65.0 million and $26.1 million at December 31, 2014 and 2013, respectively, for which deferred taxes have not been provided as such earnings are presumed to be indefinitely reinvested in the foreign subsidiaries. If at some future date these earnings cease to be indefinitely reinvested and are repatriated, the Company may be subject to additional U.S. income taxes and foreign withholding and other taxes on such amounts. The Company continues to provide deferred taxes, as required, on the undistributed net earnings of foreign subsidiaries and unconsolidated affiliates that are not deemed to be indefinitely reinvested in operations outside the United States.
	As of December 31, 2014, 2013 and 2012 the Company had $5.1 million, $6.3 million and $27.8 million of gross unrecognized tax benefits, including interest, respectively. Of these amounts, $5.0 million, $5.9 million, and $26.8 million, respectively, represent the portion that, if recognized, would impact the Company's tax provision and the effective tax rate.
	The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. As of December 31, 2014, 2013 and 2012 the Company had $0.3 million, $0.3 million and $3.1 million accrued for the payments of interest, respectively, and no amounts accrued for penalties.
	The following is a reconciliation of the total amounts of unrecognized tax benefits excluding interest and penalties for the 2014 and 2013 annual reporting periods:
	(in millions)	2014			2013
	Balance at January 1	$	6		$	24.7
Gross increases - tax positions prior periods	0.5			3.8
Gross decreases - tax positions prior periods	(0.4		)	(4.3		)
Gross increases - current period tax positions	0.7			1.1
Decreases - settlements with taxing authorities	(0.7		)	(8.0		)
Reductions - lapse of statute of limitations	(1.2		)	(11.4		)
Other	(0.1		)	0.1
Balance at December 31	$	4.8		$	6
The Company believes it is reasonably possible that the total amount of gross unrecognized tax benefits as of December 31, 2014 could decrease by approximately $0.3 million in 2015 due to settlements with taxing authorities or lapses in the statue of limitations. Due to the various jurisdictions in which the Company files tax returns and the uncertainty regarding the timing of the settlement of tax audits, it is possible that there could be other significant changes in the amount of unrecognized tax benefits in 2015, but the amount cannot be estimated.
The Company is regularly audited by federal, state and foreign tax authorities. The Internal Revenue Service (IRS) has completed its field examination and has issued its Revenue Agents Report for 2010 and all open issues have been resolved. The IRS is currently examining the Company's taxable years 2011 and 2012. Primarily as a result of filing amended returns, which were generated by the closing of federal income tax audits, the Company is still open to state and local tax audits in major tax jurisdictions dating back to the 2004 taxable year. Following the completion in 2013 of the 2002 through 2007 Germany tax audit, the Company is no longer subject to income tax examinations by any major foreign tax jurisdiction for years prior to 2008.
The difference between the actual income tax provision (benefit) and the tax provision computed by applying the statutory Federal income tax rate to Earnings before income taxes is attributable to the following:
(in millions)	2014			2013			2012
Income tax provision at 35 percent	$	100.7		$	73.1		$	54.6

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 13 – Commitments and Contingencies
	Financial Commitments
	The Company has entered into guarantees of indebtedness of third parties, primarily in connection with customer financing programs.  Under these arrangements, the Company has guaranteed customer obligations to the financial institutions in the event of customer default, generally subject to a maximum amount that is less than total obligations outstanding.  The Company has also extended guarantees to third parties that have purchased customer receivables from Brunswick and, in certain instances, has guaranteed secured term financing of its customers.  Potential payments in connection with these customer financing arrangements generally extend over several years.  The potential cash obligations associated with these customer financing arrangements as of December 31, 2014 and December 31, 2013 were:
		Single Year Obligation						Maximum Obligation
	(in millions)	2014			2013			2014		2013
	Marine Engine	$	2.6		$	8.8		$	2.6	$	8.8
	Boat	3.7			3.1			3.7		3.1
	Fitness	24.6			24.4			29.5		28.9
	Total	$	30.9		$	36.3		$	35.8	$	40.8
	In most instances, upon repurchase of the receivable or note, the Company receives rights to the collateral securing the financing.  The Company’s risk under these arrangements is partially mitigated by the value of the collateral that secures the financing.  The Company had $1.2 million and $1.5 million accrued for potential losses related to recourse exposure at December 31, 2014 and December 31, 2013, respectively.
	The Company has also entered into arrangements with third-party lenders where it has agreed, in the event of a default by the customer, to repurchase from the third-party lender those Brunswick products repossessed from the customer.  These arrangements are typically subject to a maximum repurchase amount. The potential cash payments the Company could be required to make to repurchase collateral as of December 31, 2014 and December 31, 2013 were:
		Single Year Obligation						Maximum Obligation
	(in millions)	2014			2013			2014		2013
	Marine Engine	$	1.5		$	2.2		$	1.5	$	2.2
	Boat	54.9			62.5			54.9		62.5
	Fitness	0.4			0.3			0.4		0.3
	Total	$	56.8		$	65		$	56.8	$	65
	The Company’s risk under these repurchase arrangements is partially mitigated by the value of the products repurchased as part of the transaction.  The Company had $1.2 million and $1.7 million accrued for potential losses related to repurchase exposure at December 31, 2014 and December 31, 2013, respectively.  The Company’s repurchase accrual represents the expected losses that could result from obligations to repurchase products, after giving effect to proceeds anticipated to be received from the resale of those products to alternative dealers.
	The Company has recorded its estimated net liability associated with losses from these guarantee and repurchase obligations on its Consolidated Balance Sheets based on historical experience and current facts and circumstances.  Historical cash requirements and losses associated with these obligations have not been significant, but could increase if dealer defaults exceed current expectations.
	The Company has accounts receivable sale arrangements with third parties which are included in the guarantee arrangements discussed above.  The Company treats the sale of receivables in which the Company retains an interest as a secured obligation as the transfers of the receivables under these arrangements do not meet the requirements of a “true sale.”  Accordingly, the current portion of these arrangements of $23.7 million and $36.2 million was recorded in Accounts and notes receivable and Accrued expenses as of December 31, 2014 and December 31, 2013, respectively.  Further, the long-term portion of these arrangements of $19.6 million and $18.9 million as of December 31, 2014 and December 31, 2013, respectively, was recorded in Other long-term assets and Other long-term liabilities.
	Financial institutions have issued standby letters of credit and surety bonds conditionally guaranteeing obligations on behalf of the Company totaling $8.0 million and $12.6 million, respectively, as of December 31, 2014.  A large portion of these standby letters of credit and surety bonds are related to the Company’s self-insured workers’ compensation program as required by its insurance companies and various state agencies.  The Company has recorded reserves to cover the anticipated liabilities associated with these programs.  Under certain circumstances, such as an event of default under the Company’s revolving credit facility, or, in the case of surety bonds, a ratings downgrade, the Company could be required to post collateral to support the outstanding letters of credit and surety bonds.  The Company is not required to post letters of credit as collateral against surety bonds as of December 31, 2014.
	The Company has a collateral trust arrangement with insurance carriers and a trustee bank.  The trust is owned by the Company, but the assets are pledged as collateral against workers’ compensation related obligations in lieu of other forms of collateral including letters of credit.  In connection with this arrangement, the Company had $15.6 million and $6.5 million of cash in the trust at December 31, 2014 and December 31, 2013, respectively, which was classified as Restricted cash in the Company's Consolidated Balance Sheets. In 2014, the Company made net transfers of $9.1 million to the trust related to an increase in annual collateral requirements for the current policy year net of canceled letters of credit which had previously provided collateral against these obligations. In 2013, the insurance carrier reduced the required collateral amount, which resulted in a $6.5 million net transfer out of the trust.
	Product Warranties
	The Company records a liability for product warranties at the time revenue is recognized.  The liability is estimated using historical warranty experience, projected claim rates and expected costs per claim.  The Company adjusts its liability for specific warranty matters when they become known and the exposure can be estimated.  The Company’s warranty liabilities are affected by product failure rates as well as material usage and labor costs incurred in correcting a product failure.  If actual costs differ from estimated costs, the Company must make a revision to the warranty liability. Changes in the Company's warranty liabilities due to improvements in the Company's experience and adjustments related to changes in estimates are included as Aggregate changes for preexisting warranties presented in the table below and prior year amounts have been reclassified to conform to the current period presentation.
	The following activity related to product warranty liabilities was recorded in Accrued expenses during the years ended December 31, 2014 and December 31, 2013:
	(in millions)	2014			2013
	Balance at beginning of period	$	119.6		$	126.2
	Payments made	(55.2		)	(63.1		)
	Provisions/additions for contracts issued/sold	64.7			69.6
	Aggregate changes for preexisting warranties	(18.5		)	(13.1		)
	Balance at end of period	$	110.6		$	119.6
	Additionally, end users of the Marine Engine, Boat and Fitness segments' products may purchase a contract from the Company that extends product warranty beyond the standard period.  For certain extended warranty contracts in which the Company retains the warranty or administration obligation, a deferred liability is recorded based on the aggregate sales price for contracts sold.  The deferred liability is reduced and revenue is recognized on a straight-line basis over the contract period during which costs are expected to be incurred.  Deferred revenue associated with contracts sold by the Company that extend product protection beyond the standard product warranty period, not included in the table above, was $72.6 million and $66.8 million at December 31, 2014 and December 31, 2013, respectively, and is recorded in Accrued expenses and Other long-term liabilities.
	Legal and Environmental
	The Company accrues for litigation exposure when it is probable that future costs will be incurred and such costs can be reasonably estimated. Adjustments to estimates are recorded in the period the adjustments are identified. Management does not believe that there is a reasonable possibility that a material loss exceeding the amounts already recognized for the Company’s litigation claims and matters, if any, has been incurred. However, the ultimate resolutions of these proceedings and matters are inherently unpredictable. As such, our financial condition and results of operations could be adversely affected in any particular period by the unfavorable resolution of one or more of these proceedings or matters.
	Environmental Matters
	The Company is involved in certain legal and administrative proceedings under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 and other federal and state legislation governing the generation and disposal of certain hazardous wastes. These proceedings, which involve both on- and off-site waste disposal or other contamination, in many instances seek compensation or remedial action from the Company as a waste generator under Superfund legislation, which authorizes action regardless of fault, legality of original disposition or ownership of a disposal site. The Company has established reserves based on a range of cost estimates for all known claims.
	The environmental remediation and clean-up projects in which the Company is involved have an aggregate estimated range of exposure of approximately $39.9 million to $70.5 million as of December 31, 2014. At December 31, 2014 and 2013, the Company had reserves for environmental liabilities of $39.9 million and $42.2 million, respectively, reflected in Accrued expenses and Other long-term liabilities in the Consolidated Balance Sheets. The Company recorded environmental provisions of $1.0 million, $0.5 million and $0.9 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	The Company accrues for environmental remediation-related activities for which commitments or clean-up plans have been developed and for which costs can be reasonably estimated. All accrued amounts are generally determined in consultation with third-party experts on an undiscounted basis and do not consider recoveries from third parties until such recoveries are realized. In light of existing reserves, the Company's environmental claims, when finally resolved, are not expected, in the opinion of management, to have a material adverse effect on the Company's consolidated financial position, results of operations or cash flows.

Financial_Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	Note 14 – Financial Instruments
	The Company operates globally with manufacturing and sales facilities in various locations around the world.  Due to the Company’s global operations, the Company engages in activities involving both financial and market risks.  The Company utilizes normal operating and financing activities, along with derivative financial instruments, to minimize these risks.
	Derivative Financial Instruments. The Company uses derivative financial instruments to manage its risks associated with movements in foreign currency exchange rates, interest rates and commodity prices.  Derivative instruments are not used for trading or speculative purposes.  For certain derivative contracts, on the date a derivative contract is entered into, the Company designates the derivative as a hedge of a forecasted transaction (cash flow hedge).  The Company formally documents its hedge relationships, including identification of the hedging instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction.  This process includes linking derivatives that are designated as hedges to specific forecasted transactions.  The Company also assesses, both at the hedge’s inception and monthly thereafter, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in the anticipated cash flows of the hedged item.  If the hedging relationship ceases to be highly effective, or it becomes probable that a forecasted transaction is no longer expected to occur, gains and losses on the derivative are recorded in Cost of sales or Interest expense as appropriate.  There were no material adjustments as a result of ineffectiveness to the results of operations for the years ended December 31, 2014, 2013 and 2012. The fair value of derivative financial instruments is determined through market-based valuations and may not be representative of the actual gains or losses that will be recorded when these instruments mature due to future fluctuations in the markets in which they are traded.  The effects of derivative and financial instruments are not expected to be material to the Company’s financial position or results of operations when considered together with the underlying exposure being hedged. Use of derivative financial instruments exposes the Company to credit risk with its counterparties when the fair value of a derivative contract is an asset. The Company mitigates this risk by entering into derivative contracts with highly rated counterparties. The maximum amount of loss due to counterparty credit risk is limited to the asset value of derivative financial instruments.
	Cash Flow Hedges. The Company enters into certain derivative instruments that are designated and qualify as cash flow hedges.  The Company executes both forward and option contracts, based on forecasted transactions, to manage foreign exchange exposure mainly related to inventory purchase and sales transactions.  The Company also enters into commodity swap agreements, based on anticipated purchases of aluminum, copper and natural gas, to manage risk related to price changes.  From time-to-time, the Company enters into forward starting interest rate swaps to hedge the interest rate risk associated with the anticipated issuance of debt.
	A cash flow hedge requires that as changes in the fair value of derivatives occur, the portion of the change deemed to be effective is recorded temporarily in Accumulated other comprehensive loss, an equity account, and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings.  As of December 31, 2014, the term of derivative instruments hedging forecasted transactions ranged from one to 20 months.
	The following activity related to cash flow hedges was recorded in Accumulated other comprehensive loss as of December 31:
		Accumulated Unrealized Derivative
		Gains (Losses)
		2014								2013
	(in millions)	Pretax				After-tax				Pretax			After-tax
	Beginning balance	$	(7.5	)		$	(11.3	)		$	(7.3	)	$	(10.7	)
	Net change in value of outstanding hedges	6.5				4.4				(4.5		)	(5.3		)
	Net amount recognized into earnings (loss)	2.2				1.4				4.3			4.7
	Ending balance	$	1.2			$	(5.5	)		$	(7.5	)	$	(11.3	)
	Fair Value Hedges. From time-to-time, the Company enters into fixed-to-floating interest rate swaps to convert a portion of the Company's long-term debt from fixed to floating rate debt. An interest rate swap is entered into with the expectation that the change in the fair value of the interest rate swap will offset the change in the fair value of the debt instrument attributable to changes in the benchmark interest rate. Each period, the change in the fair value of the interest rate swap asset or liability is recorded in debt.
	Other Hedging Activity. The Company has entered into certain foreign currency forward contracts that have not been designated as a hedge for accounting purposes. These contracts are used to manage foreign currency exposure related to changes in the value of assets or liabilities caused by changes in foreign exchange rates.  The change in the fair value of the foreign currency derivative contract and the corresponding change in the fair value of the asset or liability of the Company are both recorded through earnings, each period as incurred.
	Foreign Currency. The Company enters into forward and option contracts to manage foreign exchange exposure related to forecasted transactions, and assets and liabilities that are subject to risk from foreign currency rate changes.  These exposures include: product costs; revenues and expenses; associated receivables and payables; intercompany obligations and receivables; and other related cash flows.
	Forward exchange contracts outstanding at December 31, 2014 and December 31, 2013 had notional contract values of $153.5 million and $158.0 million, respectively.  Option contracts outstanding at December 31, 2014 and December 31, 2013, had notional contract values of $87.0 million and $60.9 million, respectively.  The forward and options contracts outstanding at December 31, 2014, mature during 2015 and mainly relate to the Euro, Canadian dollar, Japanese yen, Brazilian real, British pound, Australian dollar, Swedish krona, Mexican peso, Norwegian krone and New Zealand dollar.  As of December 31, 2014, the Company estimates that during the next 12 months, it will reclassify approximately $5.3 million of net gains (based on current rates) from Accumulated other comprehensive loss to Cost of sales.
	Interest Rate. In the second quarter of 2014, the Company entered into fixed-to-floating interest rate swaps to convert a portion of the Company's long-term debt from fixed to floating rate debt. As of December 31, 2014, the outstanding swaps had notional contract values of $200.0 million, of which $150.0 million correspond to the Company's 4.625 percent Senior notes due 2021 and $50.0 million correspond to the Company's 7.375 percent Debentures due 2023. There were no fixed-to-floating interest rate swaps outstanding as of December 31, 2013. These instruments have been designated as fair value hedges, with the fair market value recorded in long-term debt as discussed in Note 16 – Debt.
	The Company also enters into forward starting interest rate swaps from time to time to hedge the interest rate risk associated with anticipated debt issuances. There were no forward starting interest rate swaps outstanding at December 31, 2014 and December 31, 2013. In connection with the issuance of $150.0 million of 4.625 percent Senior notes due 2021, in May 2013, the Company terminated the $100.0 million notional value forward starting interest swaps, which resulted in a net deferred loss of $5.8 million, which was recorded as a component of Accumulated other comprehensive loss and is being amortized to interest expense over the life of the related debt.
	As of December 31, 2014 and December 31, 2013, the Company had $5.2 million and $5.3 million, respectively, of net deferred losses associated with all forward starting interest rate swaps, which were included in Accumulated other comprehensive loss.  These amounts include gains deferred on forward starting interest rate swaps terminated in July 2006, net of losses deferred on forward starting swaps terminated in August 2008 and the forward starting swaps terminated in May 2013 discussed above.  In the second quarter of 2013, the Company recognized $1.1 million of income associated with the gains originally deferred in Accumulated other comprehensive loss resulting from the difference between the amount of new debt issued and the original notional value of swaps terminated in July 2006.  As of December 31, 2014, the Company estimates that during the next 12 months, it will reclassify approximately $0.1 million of net losses resulting from settled forward starting interest rate swaps from Accumulated other comprehensive loss to Interest expense.
	Commodity Price. The Company uses commodity swaps to hedge anticipated purchases of aluminum, copper and natural gas.  Commodity swap contracts outstanding at December 31, 2014 and December 31, 2013 had notional contract values of $22.9 million and $26.2 million, respectively.  The contracts outstanding mature through 2016.  The amount of gain or loss associated with the change in fair value of these instruments is deferred in Accumulated other comprehensive loss and recognized in Cost of sales in the same period or periods during which the hedged transaction affects earnings.  As of December 31, 2014, the Company estimates that during the next 12 months it will reclassify approximately $1.0 million in net gains (based on current prices) from Accumulated other comprehensive loss to Cost of sales.
	As of December 31, 2014, the fair values of the Company’s derivative instruments were:

Concentration of Credit Risk. The Company enters into financial instruments and invests a portion of its cash reserves in marketable debt securities with banks and investment firms with which the Company has business relationships, and regularly monitors the credit ratings of its counterparties.  The Company sells a broad range of recreational products to a worldwide customer base and extends credit to its customers based upon an ongoing credit evaluation program.  The Company’s business units maintain credit organizations to manage financial exposure and perform credit risk assessments on an individual account basis.  Accounts are not aggregated into categories for credit risk determinations.  There are no concentrations of credit risk resulting from accounts receivable that are considered material to the Company’s financial position.  Refer to Note 8 – Financing Receivables for more information.
Fair Value of Other Financial Instruments. The carrying values of the Company’s short-term financial instruments, including cash and cash equivalents, accounts and notes receivable and short-term debt, including current maturities of long-term debt, approximate their fair values because of the short maturity of these instruments.  At December 31, 2014 and 2013, the fair value of the Company’s long-term debt was approximately $460.2 million and $461.6 million, respectively, and was determined using Level 1 and Level 2 inputs described in Note 7 – Fair Value Measurements, including quoted market prices or discounted cash flows based on quoted market rates for similar types of debt.  The carrying value of long-term debt, including current maturities, was $455.7 million and $459.8 million as of December 31, 2014 and December 31, 2013, respectively.

	In June 2014, the Company amended and restated the five-year $300.0 million secured, asset-based borrowing facility it entered into during March 2011 and converted it into a five-year $300.0 million secured facility (Facility) which is in effect through 2019. Under the terms of the agreement, the security was released as of December 26, 2014. As of December 31, 2014, available borrowing capacity totaled $294.1 million, net of $5.9 million of letters of credit outstanding under the Facility.  The Company has the ability to issue up to $100.0 million in letters of credit under the Facility.  The Company had no borrowings under the Facility during the year ended December 31, 2014.  The Company initially paid a facility fee of 25.0 basis points per annum, however in August 2014, the fee was adjusted to 20.0 basis points per annum based on the Company's leverage ratio.  Once the Company achieves the Investment Grade Release Conditions, the facility fee per annum will be within a range of 12.5 to 35.0 basis points based on the Company's credit rating. The Investment Grade Release Conditions are defined as the date upon which the Company receives an investment grade credit rating by either Standard & Poor's or Moody's and meets the leverage ratio requirements of less than or equal to 2.25:1.00 for the prior two fiscal quarters. Under the terms of the Facility, the Company has two borrowing options, including borrowing at a rate tied to adjusted LIBOR plus a spread of 130.0 basis points or a base rate plus a margin of 30.0 basis points. The rates are determined by a leverage ratio, with a range of 130.0 to 190.0 basis points for LIBOR rate borrowings and a range of 30.0 to 90.0 basis points for base rate borrowings, until the occurrence of the Investment Grade Release Conditions, on and after which the rate will be determined by the Company’s credit ratings, with a range of 100.0 to 190.0 basis points for LIBOR rate borrowings and a range of 0.0 to 90.0 basis points for base rate borrowings.
	The Company is required to maintain compliance with two financial covenants included in the Facility - a minimum interest coverage ratio and a maximum leverage ratio.  The minimum interest coverage ratio, as defined in the agreement, is not permitted to be less than 3.50 to 1.00. The maximum leverage ratio, as defined in the agreement, is not permitted to be more than 3.00 to 1.00, unless the Company completes an acquisition of more than $100.0 million, which increases the maximum leverage ratio to 3.25 to 1.00 for the twelve months following the acquisition. As of December 31, 2014, the Company was in compliance with these two financial covenants in the Facility.
	In May 2013, the Company completed an offering of $150.0 million aggregate principal amount of 4.625 percent Senior notes due 2021 under a private offering to qualified institutional buyers in accordance with Rule 144A, and to persons outside the U.S. pursuant to Regulation S, under the Securities Act of 1933, as amended. Interest on the notes is payable semi-annually on May 15 and November 15 of each year, starting on November 15, 2013. The Company has the option to redeem some or all of the notes prior to maturity. The proceeds from this offering and cash on hand, including the proceeds from the liquidation of the Company's marketable securities, were used to repurchase $249.8 million of the Company's outstanding 11.250 percent Senior Secured Notes due 2016. In connection with this repurchase, the Company recorded a Loss on early extinguishment of debt in the Consolidated Statements of Operations of $32.3 million during the second quarter 2013.
	As provided under the terms of its loan agreement with the Fond du Lac County Economic Development Corporation, which is secured by the Company's property located in Fond du Lac, Wisconsin, up to a maximum of 43 percent of the principal due annually can be forgiven if the Company achieves certain employment targets as outlined in the agreement. The amount of loan forgiveness is based on average employment levels at the end of the previous four quarters. Total loan forgiveness was $2.1 million or 43 percent of the principal due for both the years ended December 31, 2014 and December 31, 2013.
	The Company’s debt repurchase activity for the years ended December 31, 2014 and December 31, 2013 was as follows:

Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract]
Postretirement Benefits	Note 17 – Postretirement Benefits
	Overview. The Company has defined contribution plans, qualified and nonqualified defined benefit pension plans, and other postretirement benefit plans covering substantially all of its employees. The Company's contributions to its defined contribution plans include a match and an annual discretionary contribution and are based on various percentages of compensation, and in some instances are based on the amount of the employees' contributions to the plans. The expense related to the defined contribution plans was $38.9 million, $35.8 million and $34.5 million in 2014, 2013 and 2012, respectively. Company contributions to multiemployer plans were $0.1 million, $0.1 million and $0.1 million in 2014, 2013 and 2012, respectively. The multiemployer plans are not significant individually or in the aggregate.
	The Company's domestic pension and retiree health care and life insurance benefit plans, which are discussed below, provide benefits based on years of service and, for some plans, average compensation prior to retirement. Benefit accruals are frozen for all plan participants. The Company uses a December 31 measurement date for these plans. The Company's foreign postretirement benefit plans are not significant individually or in the aggregate.
	Plan Developments. During 2014, the Company offered a voluntary lump sum pension payment opportunity to certain terminated vested U.S. pension plan participants. Total lump sum payments of $80.7 million, of which $71.9 million were considered settlement payments, for those participants electing to receive lump sums were made in 2014 using pension plan assets. The Company recognized pretax settlement losses of $27.9 million in the fourth quarter of 2014 for those plans where the settlement payment exceeded the sum of the plans' service and interest costs. Additionally, the Company initiated the process to offer lump sum payments to certain active pension plan participants, which is expected to be completed in November 2015. The Company expects to make approximately $70 million in payments from the plans in connection with this action and to incur an estimated settlement loss of $30 million to $35 million. However, since the final result of the offering is presently unknown, these amounts are subject to change.
	Costs. Pension and other postretirement benefit costs included the following components for 2014, 2013 and 2012:
		Pension Benefits											Other Postretirement Benefits

	The funded status of these pension plans includes the projected and accumulated benefit obligations for the Company's nonqualified pension plan of $39.7 million and $37.9 million at December 31, 2014 and 2013, respectively. The Company's nonqualified pension plan and other postretirement benefit plans are not funded.
	The amounts included in the Company's Consolidated Balance Sheets as of December 31, 2014 and 2013, were as follows:
		Pension Benefits								Other Postretirement Benefits
	(in millions)	2014				2013				2014			2013
	Accrued expenses	$	3.8			$	3.8			$	4.9		$	5.8

	Net amount recognized	$	349.5			$	293.3			$	49.5		$	47.7
	As of December 31, 2014 and 2013, the projected and accumulated benefit obligations for all of the Company's pension plans were in excess of plan assets. The projected and accumulated benefit obligations and fair value of plan assets for the Company's qualified and nonqualified pension plans at December 31 were as follows:
	(in millions)	2014				2013
	Projected benefit obligation	$	1,315.40			$	1,249.30
	Accumulated benefit obligation	$	1,315.40			$	1,249.30
	Fair value of plan assets	$	965.9			$	956
	Funded status	73		%		77		%
	Accumulated Other Comprehensive Income (Loss). The following pretax activity related to pensions and other postretirement benefits was recorded in Accumulated other comprehensive income (loss) as of December 31:
		Pension Benefits								Other Postretirement Benefits

	Total	$	528.6			$	441.3			$	(4.3	)	$	(10.2	)
The estimated pretax net actuarial loss in Accumulated other comprehensive income (loss) at December 31, 2014, expected to be recognized as a component of net periodic benefit cost in 2015 for the Company's pension plans, is $20.0 million, which excludes an estimated amount to be recognized for settlement losses in 2015. The estimated pretax prior service credit and net actuarial loss in Accumulated other comprehensive income (loss) at December 31, 2014, expected to be recognized as components of net periodic benefit cost in 2015 for the Company's other postretirement benefit plans, are $0.7 million and $1.3 million, respectively.
Prior service costs and credits associated with other postretirement benefits are being amortized on a straight-line basis over the average future working lifetime to full eligibility for active hourly plan participants and over the average remaining life expectancy for those plans' participants who are fully eligible for benefits. Actuarial gains and losses in excess of 10 percent of the greater of the benefit obligation or the market value of assets are amortized over the remaining service period of active plan participants and over the average remaining life expectancy of inactive plan participants.
Other Postretirement Benefits. Once participants eligible for other postretirement benefits turn 65 years old, the health care benefits become a flat dollar amount based on age and years of service. The assumed health care cost trend rate for other postretirement benefits for pre-age 65 benefits as of December 31 was as follows:
	Pre-age 65 Benefits
	2014			2013
Health care cost trend rate for next year	7.1	%		7.3	%
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)	4.5	%		4.5	%
Year rate reaches the ultimate trend rate	2028			2028
The health care cost trend rate assumption has an effect on the amounts reported. A one percent change in the assumed health care trend rate at December 31, 2014, would have the following effects:
(in millions)	One Percent Increase				One Percent Decrease
Effect on total service and interest cost	$	—			$	—
Effect on accumulated postretirement benefit obligation	$	0.2			$	(0.2	)
The Company monitors the cost of health care and life insurance benefit plans and reserves the right to make additional changes or terminate these benefits in the future.
Assumptions. In October 2014, the Society of Actuaries (SOA) issued updated mortality tables (RP-2014) and a mortality improvement scale (MP-2014), which reflect longer life expectancies than previously projected. The SOA RP-2014 and MP-2014 were considered in developing the Company's updated mortality assumptions for pension and postretirement benefit obligations recognized at December 31, 2014, and the amounts estimated for 2015 pension and postretirement benefit expense. The updated mortality assumptions resulted in an increase of approximately $59 million and $2 million in the Company's pension and postretirement benefit obligations, respectively, at December 31, 2014.
Weighted average assumptions used to determine pension and other postretirement benefit obligations at December 31 were as follows:
	Pension Benefits						Other Postretirement Benefits
	2014			2013			2014			2013
Discount rate	3.95	%		4.85	%		3.75	%		4.4	%
Rate of compensation increase(A)	—			—			—			—
(A) Assumption used in determining pension benefit obligation only. The rate of compensation increase was reduced to 0.00% at December 31, 2008, as a result of the decision to freeze future benefit accruals for those plans where benefits are based on average compensation.
Weighted average assumptions used to determine net pension and other postretirement benefit costs for the years ended December 31 were as follows:
	2014		2013		2012
Discount rate for pension benefits	4.85%		4.00%		4.50%
Discount rate for other postretirement benefits	4.40%		3.60%		4.20%
Long-term rate of return on plan assets(A)	6.25%		6.50%		7.00%
Rate of compensation increase(A)	—		—		—
(A) Assumption used in determining pension benefit cost only.
The Company utilizes a yield curve analysis to determine the discount rates for pension and other postretirement benefit obligations. The yield curve analysis matches the cash flows of the Company's benefit obligations. The yield curve consisted of spot interest rates at half year increments for each of the next 30 years and was developed based on pricing and yield information for high quality corporate bonds rated Aa by either Moody's or Standard & Poor's, private placement bonds that are traded in reliance with Rule 144A and are at least two years from date of issuance, bonds with make-whole provisions and bonds issued by foreign corporations that are denominated in U.S. dollars, excluding callable bonds and bonds less than a minimum size and other filtering criteria. Additionally, the Company's yield curve methodology includes bonds having a yield that is greater than the regression mean yield curve as the Company believes this methodology represents an appropriate estimate of the rates at which the Company could effectively settle its pension obligations.
The Company evaluates its assumption regarding the estimated long-term rate of return on plan assets based on historical experience, future expectations of investment returns, asset allocations, investment strategies and views of investment professionals. The Company's long-term rate of return on assets assumptions of 6.25 percent for 2014, 6.50 percent for 2013, and 7.00 percent for 2012, reflect expectations of projected weighted average market returns for the plans' assets. These changes in expected returns also reflected adjustments to the Company's targeted asset allocation.
Master Trust Investments. Assets of the Company's Master Pension Trust (Trust) are invested solely in the interest of the plan participants for the purpose of providing benefits to participants and their beneficiaries. Investment decisions within the Trust are made after giving appropriate consideration to the prevailing facts and circumstances that a prudent person acting in a like capacity would use in a similar situation, and follow the guidelines and objectives established within the investment policy statement for the Trust. In general, the Trust's investment strategy is to invest in a diversified portfolio of assets that will generate returns equal to or in excess of the discount rate used to measure plan liabilities. The excess returns generated from this strategy will contribute to improving the funded position of the plan. In order for returns to exceed the discount rate, the Trust will invest in equities and other asset classes which have had historically higher rates of returns than fixed income investments. These asset classes have also had lower correlations to changes in plan liabilities resulting from changes in the discount rate. All investments are continually monitored and reviewed, with a focus on asset allocation, investment vehicles and performance of the individual investment managers, as well as overall Trust performance. Over time, the Company will be shifting a greater percentage of the Trust's assets into long-term fixed-income securities, with an objective of achieving an improved matching of asset returns with changes in liabilities. The Company will consider these changes in asset allocation based on a number of factors including improvements in the plans' funded position, performance of equity investments and changes in the discount rate used to measure plan liabilities.
The Trust asset allocation at December 31, 2014 and 2013, and target allocation for 2015 are as follows:
	2014		2013		Target
					Allocation for 2015
Equity securities:
United States	17%		25%		17%
International	3%		5%		3%
Fixed-income securities	66%		46%		80%

The following is a description of the valuation methodologies used for assets and liabilities measured at fair value. See Note 7 – Fair Value Measurements for further description of the procedures the Company performs with respect to its Level 2 measurements:
Equity securities: The indexed equity funds are valued at the net asset value (NAV) provided by the investment managers. The NAV is based on the value of the underlying assets owned by the fund, minus its liabilities, divided by the number of units outstanding. The indexed equity funds are invested in portfolios of equity securities with the goal of matching returns to specific indices. Investments in United States equity securities are invested in an index fund that tracks the Russell 3000 index, which is an all cap market index. International equities are invested in an index fund that tracks the MSCI EAFE index, which is an index that tracks international equity markets of developed countries worldwide.
Corporate debt securities: Corporate debt securities are valued based on prices provided by third-party pricing sources, which are based on estimated prices at which a dealer would pay for or sell a security.
Government debt securities: U.S. Treasury bonds are valued using quoted market prices in active markets. Other agency securities are valued based on prices provided by third-party pricing sources, which are based on estimated prices at which a dealer would pay for or sell a security.
Short-term investments, commingled funds: Short-term investments and commingled funds are valued at the NAV provided by the investment managers. The NAV is based on the value of the underlying assets owned by the fund, minus its liabilities, divided by the number of units outstanding. Investments in fixed income commingled funds include long-duration corporate bonds and government-related securities with the goal of preserving capital and maximizing total return consistent with prudent investment management.
Other investments: Derivative instruments are valued using market indices.
There were no pension plan assets using significant unobservable inputs (Level 3) for the years ended December 31, 2014 and December 31, 2013.
Expected Cash Flows. The expected cash flows for the Company's pension and other postretirement benefit plans follow:

Share-based Compensation [Abstract]
Stock Plans and Management Compensation	Note 18 – Stock Plans and Management Compensation
	On May 7, 2014, the Company's shareholders approved the Brunswick Corporation 2014 Stock Incentive Plan (Plan), which replaced the Company's 2003 Stock Incentive Plan. Under the Plan, the Company may grant stock options, stock appreciation rights (SARs), non-vested stock awards and performance awards to executives, other employees and non-employee directors, with 5.0 million shares from treasury shares and from authorized, but unissued, shares of common stock initially available for grant, in addition to any shares reacquired by the Company through the forfeiture of past awards, or settlement of such awards in cash. As of December 31, 2014, 5.4 million shares remained available for grant.
	Stock Options and SARs
	Through 2004, the Company issued stock options, and between 2005 and 2012, the Company issued stock-settled SARS. The Company did not issue SARS in 2014 or 2013. Generally, stock options and SARs are exercisable over a period of 10 years, or as otherwise determined by the Human Resources and Compensation Committee of the Board of Directors, and subject to vesting periods of generally 4 years. However, with respect to stock options and SARs, all grants vest immediately: (i) in the event of a change in control; (ii) upon death or disability of the grantee; or (iii) with respect to awards granted prior to 2008, upon the sale or divestiture of the business unit to which the grantee is assigned. With respect to stock option and SAR awards granted prior to 2006, grantees continued to vest in accordance with the applicable vesting schedule even upon termination of employment if the sum of (A) the age of the grantee, and (B) the grantee's total number of years of service, equals 65 or more. With respect to SARs granted in 2006 through April 2009, grantees continue to vest in accordance with the vesting schedule even upon termination if (A) the grantee has attained the age of 62, and (B) the grantee's age plus total years of service equals 70 or more.
	With respect to SARs granted in May 2009 and thereafter, grantees continue to vest in accordance with the vesting schedule even upon termination if (A) the grantee has attained the age of 62, or (B) the grantee's age plus total years of service equals 70 or more. An additional provision applies that prorates the grant in the event of termination prior to the first anniversary of the date of grant, provided the participant had met the appropriate retirement age definition of rule of 70 or age 62.

	The Company did not grant SARs in 2014 or 2013. The weighted average fair value of individual SARs granted during 2012 was $12.70. The Company estimated the fair value of each grant on the date of grant using the Black-Scholes-Merton pricing model, utilizing the following weighted average assumptions for 2012:
		2012
	Risk-free interest rate	1.1	%
	Dividend yield	0.2	%
	Volatility factor (A)	58.3	%
	Weighted average expected life	5.2 – 6.7 years
	(A) The Company uses a combination of implied and historical volatility in calculating the fair value of each grant.
	Total stock option and SARs expense was $1.3 million, $3.0 million and $6.4 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Non-vested stock awards
	The Company grants both stock-settled and cash-settled non-vested stock units and awards to key employees as determined by the Human Resources and Compensation Committee. Non-vested stock units and awards have vesting periods of three or four years. Non-vested stock units and awards are eligible for dividends, which are reinvested and non-voting. All non-vested units and awards have restrictions on the sale or transfer of such awards during the vesting period.
	Generally, grants of non-vested stock units and awards are forfeited if employment is terminated prior to vesting. Non-vested stock units and awards granted in 2006 and later vest pro rata if (A) the grantee has attained the age of 62, or (B) the grantee's age plus total years of service equals 70 or more.
	The Company recognizes the cost of non-vested stock units and awards on a straight-line basis over the requisite service period. Additionally, cash-settled non-vested stock units and awards are recorded as a liability in the balance sheet and adjusted to fair value each reporting period through stock compensation expense. During December 31, 2014, 2013 and 2012, there was $10.5 million, $10.1 million and $6.4 million, respectively, charged to compensation expense for non-vested stock awards.
	The weighted average price per non-vested stock award at grant date was $40.41, $34.64 and $23.79 for the non-vested stock awards granted in 2014, 2013 and 2012, respectively. Non-vested stock award activity for all plans for the three years ended December 31 was as follows:
	(in thousands)	2014		2013			2012
	Outstanding at January 1	815		798			541
	Granted	322		298			306
	Released	(220	)	(266	)		(20	)
	Forfeited	(37	)	(15	)		(29	)
	Outstanding at December 31	880		815			798
	As of December 31, 2014, there was $5.7 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements. The Company expects this cost to be recognized over a weighted average period of 0.8 years.
	Performance Awards
	In February 2014, 2013 and 2012, the Company granted performance shares to certain senior executives. The share awards are based on two performance measures--a cash flow return on investment (CFROI) measure and a total shareholder return (TSR) modifier. Target performance shares are earned based on a one-year CFROI performance period, commencing at the beginning of the calendar year of each grant. The performance shares earned from CFROI performance are then subject to a TSR modifier based on stock price performance measured against a predefined comparator group over a three-year performance period which starts at the beginning of the calendar year of each grant.
	Additionally, in February 2014 and 2013, the Company granted 24,600 and 26,000 performance shares, respectively, to certain officers and certain senior managers based solely on the CFROI measure utilizing the same one-year performance period mentioned above. Expense related to each grant is recognized over the vesting period and is based on projections of probable attainment of the CFROI measure and the projected TSR modifier used to determine performance awards. Amounts charged to compensation expense for the years ended December 31, 2014, 2013 and 2012 were $6.5 million, $5.0 million and $2.2 million, respectively.
	The fair values of the senior executives' performance share award grants with a TSR modifier at the grant date in 2014, 2013 and 2012 were $41.38, $35.93 and $26.81, respectively, which were estimated using the Monte Carlo valuation model, and incorporated the following assumptions:
		2014		2013			2012
	Risk-free interest rate	0.6	%	0.4	%		0.4	%
	Dividend yield	1	%	0.1	%		0.2	%
	Volatility factor	43.7	%	53	%		67.9	%
	Expected life of award	2.9 years		2.9 years			2.9 years
	The fair value of certain officers and certain senior managers' performance awards granted based solely on the CFROI performance factor was $40.44 and $34.65, which was equal to the stock price on the date of grant in 2014 and 2013, respectively.
	Performance award activity for the years ended December 31, 2014, 2013 and 2012 was as follows:
	(in thousands)	2014		2013			2012
	Outstanding at January 1	249		96			—
	Granted	152		153			99
	Forfeited	(25	)	—			(3	)
	Outstanding at December 31	376		249			96
	As of December 31, 2014, the Company had $0.8 million of total unrecognized compensation cost related to performance awards. The Company expects this cost to be recognized over a weighted average period of 0.7 years.
Excess Tax Benefits
For tax purposes, share-based compensation expense is deductible in the year of exercise or release based on the intrinsic value of the award on the date of exercise or release. For financial reporting purposes, share-based compensation expense is based upon grant-date fair value, which is amortized over the vesting period. Excess or "windfall" tax benefits represent the excess tax deduction received by the Company resulting from the difference between the share-based compensation expense deductible for tax purposes and the share-based compensation expense recognized for financial reporting purposes. Windfall tax benefits are recorded directly to Additional paid-in capital in Shareholders' equity on the Company's Consolidated Balance Sheets. The Company has accounted for windfall tax benefits since the adoption of share-based accounting pronouncements in 2006. Windfall tax benefits for the years ended December 31, 2014, 2013 and 2012 were $8.4 million, $37.2 million and $5.3 million, respectively, and are netted out of cash from operating activities and are reflected as a cash inflow from financing activities in the Consolidated Statements of Cash Flows.
Director Awards
The Company issues stock awards to non-employee directors in accordance with the terms and conditions determined by the Nominating and Corporate Governance Committee of the Board of Directors.  A portion of each director’s annual fee is paid in Brunswick common stock, the receipt of which may be deferred until a director retires from the Board of Directors.  Each director may elect to have the remaining portion paid in cash, in Brunswick common stock distributed at the time of the award, or in deferred Brunswick common stock units with a 20 percent premium.

	Estimates in these consolidated financial statements include, but are not limited to:
	•Allowances for doubtful accounts;
	•Inventory valuation reserves;
	•Reserves for dealer allowances;
	•Reserves related to repurchase and recourse obligations;
	•Warranty related reserves;
	•Losses on litigation and other contingencies;
	•Environmental reserves;
	•Insurance reserves;
	•Valuation of goodwill and other intangible assets;
	•Impairments of long-lived assets;
	•Reserves related to restructuring activities;
	•Postretirement benefit liabilities;
	•Valuation allowances on deferred tax assets; and
	•Income tax reserves.
	The Company records a reserve when it is probable that a loss has been incurred and the loss can be reasonably estimated. The Company establishes its reserves based on its best estimate within a range of losses. If the Company is unable to identify the best estimate, the Company records the minimum amount in the range.
Cash and Cash Equivalents	Cash and Cash Equivalents. The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. These investments include, but are not limited to, investments in money market funds, bank deposits, federal government and agency debt securities and commercial paper.
Investments in Marketable Securities	Investments in Marketable Securities. The Company classifies investments in debt securities that are not considered to be cash equivalents as Short-term investments in marketable securities as discussed in Note 9 – Investments. Short-term investments in marketable securities have a stated maturity of twelve months or less from the balance sheet date. These securities are considered as available for sale and are reported at fair value. Unrealized gains and losses would be recorded net of tax as a component of Accumulated other comprehensive loss in Unrealized investment losses within Shareholders' equity. Declines in market value from the original cost deemed to be "other-than-temporary" are charged to Other income, net, in the period in which the loss occurs. The Company considers both the duration for which a decline in value has occurred and the extent of the decline in its determination of whether a decline in value has been “other than temporary.” Realized gains and losses are calculated based on the specific identification method and are included in Other income, net, in the Consolidated Statement of Operations.
	The Company invests a portion of its cash reserves in marketable debt securities.  These investments are reported in Short-term investments in marketable securities on the Consolidated Balance Sheets. Furthermore, the debt securities have readily determinable market values and are being accounted for as available-for-sale investments.  These investments are recorded at fair value with unrealized gains and losses reflected in Accumulated other comprehensive loss, a component of Shareholders’ equity on the Company’s Consolidated Balance Sheets, on an after-tax basis.
Restricted Cash	Restricted Cash. The Company considers the cash deposited in a trust that is pledged as collateral against certain workers' compensation related obligations to be restricted cash. Refer to Note 13 – Commitments and Contingencies for more information.
Accounts and Notes Receivable and Allowance for Doubtful Accounts	Accounts and Notes Receivable and Allowance for Doubtful Accounts. The Company carries its accounts and notes receivable at their face amounts less an allowance for doubtful accounts. On a regular basis, the Company records an allowance for uncollectible receivables based upon known bad debt risks and past loss history, customer payment practices and economic conditions. Actual collection experience may differ from the current estimate of net receivables. A change to the allowance for doubtful accounts may be required if a future event or other change in circumstances results in a change in the estimate of the ultimate collectability of a specific account.
	The Company treats the sale of receivables in which the Company retains an interest as a secured obligation. Accordingly, the short-term portion of the receivables sold that are subject to recourse is recorded in Accounts and notes receivable and Accrued expenses in the Consolidated Balance Sheets.
Inventories	Inventories. Inventories are valued at the lower of cost or market, with market based on replacement cost or net realizable value. Approximately 47 percent and 48 percent of the Company's inventories were determined by the first-in, first-out method (FIFO) at December 31, 2014 and December 31, 2013, respectively. Remaining inventories valued at the last-in, first-out method (LIFO), were $122.4 million and $118.0 million lower than the FIFO cost of inventories at December 31, 2014 and 2013, respectively. The Company has reclassified certain prior year work-in-process inventory balances to raw materials to conform to the current period presentation. Additionally, certain prior year LIFO reserves have been reclassified from finished goods to work-in-process and raw materials to reflect a proportional allocation between inventory categories to conform to the current period presentation. Inventory cost includes material, labor and manufacturing overhead.
Property	Property. Property, including major improvements and product tooling costs, is recorded at cost. Product tooling costs principally comprise the cost to acquire and construct various long-lived molds, dies and other tooling owned by the Company and used in its manufacturing processes. Design and prototype development costs associated with product tooling are expensed as incurred. Maintenance and repair costs are also expensed as incurred. Depreciation is recorded over the estimated service lives of the related assets, principally using the straight-line method. Buildings and improvements are depreciated over a useful life of five to forty years. Equipment is depreciated over a useful life of two to twenty years. Product tooling costs are amortized over the shorter of the useful life of the tooling or the anticipated life of the applicable product, for a period not to exceed eight years. Gains and losses recognized on the sale and disposal of property are included in either Selling, general and administrative expenses or Restructuring, exit and impairment charges as appropriate.
Software Development Costs	Software Development Costs. The Company expenses all software development and implementation costs incurred until the Company has determined that the software will result in probable future economic benefit and management has committed to funding the project. Once this is determined, external direct costs of material and services, payroll-related costs of employees working on the project and related interest costs incurred during the application development stage are capitalized. These capitalized costs are amortized over three to seven years. All other related costs, including training costs and costs to re-engineer business processes are expensed as incurred.
Goodwill and Other Intangibles	Goodwill and Other Intangibles. Goodwill and other intangible assets primarily result from business acquisitions. The excess of cost over net assets of businesses acquired is recorded as goodwill. The Company reviews these assets for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The reporting units with goodwill balances are the Company's Fitness and Marine Engine segments.
	For 2014, the impairment test for goodwill was a two-step process. The first step compares the fair value of a reporting unit with its carrying amount. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired. If the carrying amount of the reporting unit exceeds its fair value, the second step is performed to measure the amount of the impairment loss, if any. In this second step, the implied fair value of the reporting unit’s goodwill is compared with the carrying amount of the goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess, not to exceed the carrying amount of the goodwill.
	The Company calculates the fair value of its reporting units considering both the income approach and the guideline public company method.  The income approach calculates the fair value of the reporting unit using a discounted cash flow approach utilizing a Gordon Growth model.  Internally forecasted future cash flows, which the Company believes reasonably approximate market participant assumptions, are discounted using a weighted average cost of capital (Discount Rate) developed for each reporting unit.  The Discount Rate is developed using market observable inputs, as well as considering whether or not there is a measure of risk related to the specific reporting unit’s forecasted performance.  Fair value under the guideline public company method is determined by applying market multiples for that reporting unit’s comparable public companies to the unit’s financial results.  The key uncertainties in these calculations are the assumptions used in a reporting unit’s forecasted future performance, including revenue growth and operating margins, as well as the perceived risk associated with those forecasts, and selecting representative market multiples.
	During 2011, the Company early adopted an amendment to the Intangibles - Goodwill and Other topic of the Accounting Standards Codification. The Company determined through its qualitative assessment during 2013 and 2012 that it was not “more likely than not” that the fair values of its reporting units are less than their carrying values. As a result, the Company was not required to perform the two-step impairment test for 2013 or 2012. As part of the qualitative assessment process, the Company calculates the fair value of its reporting units using the income approach as described above. The Company compares the fair value of a reporting unit with its carrying amount to support its qualitative assessment conclusions.
	The fair value of the Company's reporting units was significantly above their carrying values as of December 31, 2014. The Company did not record any goodwill impairments in 2014, 2013 or 2012.
	The Company's primary intangible assets are customer relationships and trade names acquired in business combinations. The costs of amortizable intangible assets are amortized over their expected useful lives, typically between three and fifteen years, using the straight-line method. Intangible assets that are subject to amortization are evaluated for impairment using a process similar to that used to evaluate long-lived assets described below. Intangible assets not subject to amortization are assessed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The impairment test for indefinite-lived intangible assets consists of a comparison of the fair value of the intangible asset with its carrying amount. An impairment loss is recognized for the amount by which the carrying value exceeds the fair value of the asset. The fair value of trade names is measured using a relief-from-royalty approach, which assumes the value of the trade name is the discounted cash flows of the amount that would be paid to third parties had the Company not owned the trade name and instead licensed the trade name from another company. Higher royalty rates are assigned to premium brands within the marketplace based on name recognition and profitability, while other brands receive lower royalty rates. The basis for future cash flow projections is internal revenue forecasts by brand, which the Company believes represent reasonable market participant assumptions, to which the selected royalty rate is applied. These future cash flows are discounted using the applicable Discount Rate, which considers the annual goodwill impairment testing process noted above, as well as any potential risk premium to reflect the inherent risk of holding a standalone intangible asset. The key uncertainties in this calculation are the selection of an appropriate royalty rate and assumptions used in developing internal revenue growth forecasts, as well as the perceived risk associated with those forecasts in developing the Discount Rate.
	The Company did not record any indefinite-lived intangible asset impairments during 2014 and 2013. In 2012, the Company recorded $0.8 million of indefinite-lived intangible asset impairments during the annual impairment testing. An additional $0.7 million of indefinite-lived intangible asset impairment charges were recorded in 2012 for trade names connected with brands experiencing continued weakness in the fiberglass sterndrive boat market segments as well as the refinement of its North American boat product portfolio. Refer to Note 3 – Restructuring Activities for further discussion.
Equity Investments	Equity Investments. For investments in which Brunswick owns or controls from 20 percent to 50 percent of the voting shares, which includes all of Brunswick's unconsolidated joint venture investments, the Company uses the equity method of accounting. The Company's share of net earnings or losses from equity method investments is included in the Consolidated Statements of Operations. The Company accounts for other investments, over which the Company does not have the ability to exercise significant influence, under the cost method of accounting.
	The Company periodically evaluates the carrying value of its investments, and at December 31, 2014 and 2013, such investments were recorded at the lower of cost or fair value.
Long-Lived Assets	Long-Lived Assets. The Company continually evaluates whether events and circumstances have occurred that indicate the remaining estimated useful lives of its definite-lived intangible assets--excluding goodwill and indefinite-lived trade names--and other long-lived assets may warrant revision or that the remaining balance of such assets may not be recoverable. Once an impairment indicator is identified, the Company tests for recoverability of the related asset group using an estimate of undiscounted cash flows over the remaining asset group's life. If an asset group's carrying value is not recoverable, the Company records an impairment loss based on the excess of the carrying value of the asset group over the long-lived asset group's fair value. Fair value is determined using observable inputs, including the use of appraisals from independent third parties, when available, and, when observable inputs are not available, based on the Company's assumptions of the data that market participants would use in pricing the asset, based on the best information available in the circumstances. Specifically, the Company uses discounted cash flows to determine the fair value of the asset when observable inputs are unavailable. The Company tested its long-lived asset balances for impairment as indicators presented themselves during 2014, 2013 or 2012, resulting in impairment charges of $1.5 million, $7.1 million and $11.4 million, respectively, which are recognized in Restructuring, exit and impairment charges and Selling, general and administrative expense in the Consolidated Statements of Operations.
Other Long-Term Assets	Other Long-Term Assets. Other long-term assets are mainly long-term receivables originated by the Company and assigned to third parties, deferred debt issuance costs and other long-term notes receivable. As of December 31, 2014 and 2013, amounts assigned to third parties totaled $19.6 million and $18.9 million, respectively. The assignment of these instruments does not meet sale criteria as a result of the Company's contingent obligation to repurchase the receivables in the event of customer non-payment and therefore is treated as a secured obligation. Accordingly, these amounts were recorded in the Consolidated Balance Sheets under Other long-term assets and Long-term liabilities – Other. Fees and expenses related to acquiring the Company's debt are capitalized and then amortized over the life of the corresponding debt. As of December 31, 2014 and 2013, deferred debt issuance costs were $7.3 million and $6.6 million, respectively.
Revenue Recognition	Revenue Recognition. Brunswick's revenue is derived primarily from the sale of boats, marine engines, marine parts and accessories, fitness equipment and billiards tables. Revenue is recognized in accordance with the terms of the sale, primarily upon shipment to customers, once the sales price is fixed or determinable and collectability is reasonably assured. Brunswick offers discounts and sales incentives that include retail promotions, rebates and manufacturer coupons that are recorded as reductions of revenues in Net sales in the Consolidated Statements of Operations. The estimated liability and reduction in revenue for sales incentives is recorded at the later of when the program has been communicated to the customer or at the time of sale. Revenues from freight are included as a part of Net sales in the Consolidated Statements of Operations, whereas shipping, freight and handling costs are included in Cost of sales.
Advertising Costs	Advertising Costs. The Company records advertising and promotion costs in Selling, general and administrative expense in the Consolidated Statements of Operations in the period when the advertising first takes place.
Foreign Currency	Foreign Currency. The functional currency for the majority of Brunswick's operations is the U.S. dollar. All assets and liabilities of operations with a functional currency other than the U.S. dollar are translated at period end current rates. The resulting translation adjustments are recorded in Accumulated other comprehensive income (loss), net of tax. Revenues and expenses of operations with a functional currency other than the U.S. dollar are translated at the average exchange rates for the period.
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss). Accumulated other comprehensive loss includes prior service costs and credits and net actuarial gains and losses for defined benefit plans, currency translation adjustments and unrealized derivative and investment gains and losses, all net of tax. The net effect of these items reduced Shareholders' equity on a cumulative basis by $480.5 million and $401.5 million as of December 31, 2014 and 2013, respectively. The change from 2013 to 2014 was primarily due to changes in Net actuarial losses related to unfavorable adjustments to defined benefit plan liabilities resulting from decreases in the discount rate and changes to assumptions regarding mortality, partially offset by better than expected return on plan assets, the amortization of net actuarial losses and the impact of lump sum payout actions during 2014. Additionally, the strengthening of the U.S. dollar against foreign currencies resulted in unfavorable currency translation adjustments.
Stock-Based Compensation	Stock-Based Compensation. The Company records amounts for all share-based payments to employees, including grants of stock options and the compensatory elements of employee stock purchase plans over the vesting period in the income statement based upon their fair values at the date of the grant. Share-based employee compensation costs are recognized as a component of Selling, general and administrative expense in the Consolidated Statements of Operations. See Note 18 – Stock Plans and Management Compensation for a description of the Company's accounting for stock-based compensation plans.
Derivatives	Derivatives. The Company uses derivative financial instruments to manage its risk associated with movements in foreign currency exchange rates, interest rates and commodity prices. These instruments are used in accordance with guidelines established by the Company's management and are not used for trading or speculative purposes. All derivatives are recorded on the Consolidated Balance Sheets at fair value. See Note 14 – Financial Instruments for further discussion.
Recent Accounting Pronouncements	Recent Accounting Pronouncements.  The Company evaluates the pronouncements of various authoritative accounting organizations, primarily the Financial Accounting Standards Board (FASB), the SEC, and the Emerging Issues Task Force, to determine the impact of new pronouncements on GAAP and the impact on the Company.  The following are recent accounting pronouncements that have been adopted during 2014, or will be adopted in future periods.
	Going Concern: In August 2014, the FASB amended the Accounting Standards Codification (ASC) to provide guidance on determining when and how an entity must disclose going concern uncertainties in its financial statements. The amendment requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date of issuance of an entity's financial statements. If there is substantial doubt about the entity's ability to continue as a going concern, an entity must provide certain footnote disclosures. The amendment is effective for fiscal years, and the interim periods thereafter, beginning after December 15, 2016, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material effect on the Company's consolidated financial statements.
	Revenue Recognition: In May 2014, the FASB and International Accounting Standards Board jointly issued a final standard on revenue recognition which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This standard will supersede most current revenue recognition guidance. Under the new standard, entities are required to identify the contract with a customer; identify the separate performance obligations in the contract; determine the transaction price; allocate the transaction price to the separate performance obligations in the contract; and recognize the appropriate amount of revenue when (or as) the entity satisfies each performance obligation. The standard is effective for fiscal years, and the interim periods within those years, beginning on or after January 1, 2017. Entities have the option of using either retrospective transition or a modified approach in applying the new standard. The Company is currently evaluating the approach it will use to apply the new standard and the impact that the adoption of the new standard will have on the Company’s consolidated financial statements.
	Discontinued Operations: In April 2014, the FASB amended the ASC to raise the threshold for a disposal to qualify as a discontinued operation. Under the new guidance, a discontinued operation represents a strategic shift that has or will have a major effect on an entity's operations and financial results. The guidance also expands the disclosures for discontinued operations, including new disclosures related to individually material disposals that do not meet the definition of a discontinued operation. The amendment is effective for fiscal years, and the interim periods within those years, beginning after December 15, 2014, with early adoption permitted only for disposals that have not been reported in financial statements previously issued. The Company did not early adopt this ASC amendment and is currently evaluating the impact of adopting this ASC amendment, but does not expect it will have a material effect on the Company's consolidated financial statements.
	Unrecognized Tax Benefit: In July 2013, the FASB amended the ASC to provide guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss (NOL) carryforward, a similar tax loss, or a tax credit carryforward exists. The guidance states that entities should present an unrecognized tax benefit as a reduction of a deferred tax asset for an NOL or tax credit carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. The amendment is effective for fiscal years, and the interim periods within those years, beginning after December 15, 2013, with early adoption permitted. The Company adopted this amendment in 2014 and it did not have a material impact on the Company’s consolidated results of operations and financial condition.

	Liabilities (B)	(1.6		)	(1.4		)
	Total maximum loss exposure	$	46.5		$	46.8
	(A)	Repurchase and recourse obligations are off-balance sheet obligations provided by the Company for the Boat and Marine Engine segments, respectively, and are included within the Maximum Potential Obligations disclosed in Note 13 – Commitments and Contingencies.  Repurchase and recourse obligations are mainly related to a North American repurchase agreement with GECDF and could be reduced by repurchase activity occurring under other similar agreements with GECDF and affiliates.  The Company’s risk under these repurchase arrangements is partially mitigated by the value of the products repurchased as part of the transaction.  Amounts above exclude any potential recoveries from the value of the repurchased product. The previously reported amount of $51.8 million as of December 31, 2013, reflects repurchase and recourse obligations under the Company's global repurchase agreement that was replaced in 2013 with the North American repurchase agreement described above.
	(B)	Represents accrued amounts for potential losses related to recourse exposure and the Company’s expected losses on obligations to repurchase products, after giving effect to proceeds anticipated to be received from the resale of these products to alternative dealers.

[1]	Repurchase and recourse obligations are off-balance sheet obligations provided by the Company for the Boat and Marine Engine segments, respectively, and are included within the Maximum Potential Obligations disclosed in Note 13 b Commitments and Contingencies. Repurchase and recourse obligations are mainly related to a North American repurchase agreement with GECDF and could be reduced by repurchase activity occurring under other similar agreements with GECDF and affiliates. The Companybs risk under these repurchase arrangements is partially mitigated by the value of the products repurchased as part of the transaction. Amounts above exclude any potential recoveries from the value of the repurchased product. The previously reported amount of $51.8 million as of December 31, 2013, reflects repurchase and recourse obligations under the Company's global repurchase agreement that was replaced in 2013 with the North American repurchase agreement described above.
[2]	Represents accrued amounts for potential losses related to recourse exposure and the Companybs expected losses on obligations to repurchase products, after giving effect to proceeds anticipated to be received from the resale of these products to alternative dealers.
