Accounting Policies [Abstract]	'
Significant Accounting Policies	'
	SIGNIFICANT ACCOUNTING POLICIES
	Organization and Business
	Nautilus was founded in 1986 and incorporated in the State of Washington in 1993. Our headquarters are located in Vancouver, Washington.
	We are committed to providing innovative, quality solutions to help people achieve a fit and healthy lifestyle. Our principal business activities include designing, developing, sourcing and marketing high-quality cardio and strength fitness products and related accessories for consumer use, primarily in the United States and Canada. Our products are sold under some of the most-recognized brand names in the fitness industry: Nautilus®, Bowflex®, Schwinn®, Schwinn Fitness™ and Universal®.
	We market our products through two distinct distribution channels, Direct and Retail, which we consider to be separate business segments. Our Direct business offers products directly to consumers through television advertising, catalogs and the Internet. Our Retail business offers our products through a network of independent retail companies with stores and websites located in the United States and internationally. We also derive a portion of our revenue from the licensing of our brands and intellectual property.
	Basis of Presentation
	The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and relate to Nautilus, Inc. and its subsidiaries, all of which are wholly-owned, directly or indirectly. Intercompany transactions and balances have been eliminated in consolidation.
	Discontinued Operations
	Results from discontinued operations relate to the disposal of our former Commercial business, which began in 2009 and was completed in April 2011. We reached substantial completion of asset liquidation at December 31, 2012. However, we continue to have legal and accounting expenses as we work with authorities on final deregistration of each entity and product liability expenses associated with product previously sold into the Commercial channel.
	Results of operations and certain assets associated with the commercial business have been presented in the consolidated financial statements as discontinued operations for all periods presented.
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities in the financial statements. Our most significant estimates relate to the following:
	•	Revenue recognition;
	•	Sales discounts and allowances;
	•	Goodwill and other long-term asset valuation;
	•	Product warranty obligations;
	•	Valuation of excess and obsolete inventory;
	•	Litigation and loss contingencies;
	•	Deferred tax assets and the related valuation allowance; and
	•	Unrecognized tax benefits.
	Actual results could differ from our estimates.
	Concentrations
	Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash held in bank accounts in excess of federally-insured limits and trade receivables. Trade receivables are generally unsecured and therefore collection is affected by the economic conditions in each of our principal markets.
	We rely on third-party contract manufacturers in Asia for substantially all of our products and for certain product engineering support. Business operations could be disrupted by natural disasters, difficulties in transporting products from non-U.S. suppliers, as well as political, social or economic instability in the countries where contract manufacturers or their vendors or customers conduct business. While any such contract manufacturing arrangement could be replaced over time, the temporary loss of the services of any primary contract manufacturer could delay product shipments and cause a significant disruption in our operations.
	We derive a significant portion of our Net Sales from a small number of our Retail customers. A loss of business from one or more of these large customers, if not replaced with new business, would negatively affect our operating results and cash flows. In 2013, 2012 and 2011, one customer accounted for more than 10%, but less than 15%, of our Net Sales.
	Cash and Cash Equivalents
	All highly liquid investments with maturities of three months or less at purchase are considered to be cash equivalents. As of December 31, 2013 and 2012, cash and cash equivalents consisted entirely of cash.
	Inventories
	Inventories are stated at the lower of cost or market, with cost determined based on the first-in, first-out method. We establish inventory allowances for excess, slow-moving and obsolete inventory based on inventory levels, expected product life and forecasted sales. Inventories are written down to market value based on historical demand, competitive factors, changes in technology and product lifecycles.
	Property, Plant and Equipment
	Property, plant and equipment is stated at cost, net of accumulated depreciation. Improvements or betterments which add new functionality or significantly extend the life of an asset are capitalized. Expenditures for maintenance and repairs are expensed as incurred. The cost of assets retired, or otherwise disposed of, and the related accumulated depreciation, are removed from the accounts at the time of disposal. Gains and losses resulting from asset sales and dispositions are recognized in the period in which assets are disposed. Depreciation is recognized, using the straight-line method, over the lesser of the estimated useful lives of the assets or, in the case of leasehold improvements, the lease term, including renewal periods if we expect to exercise our renewal options. Depreciation on computer equipment, machinery and equipment and furniture and fixtures is determined based on estimated useful lives, which generally range from three-to-five years.
	Goodwill
	Goodwill consists of the excess of acquisition costs over the fair values of net assets acquired in business combinations. We review goodwill for impairment in the fourth quarter of each year and when events or changes in circumstances indicate that the carrying amount may be impaired. For this purpose, goodwill is evaluated at the reporting unit level. Our goodwill is an asset of our Direct reporting unit. We performed a qualitative assessment of goodwill in the fourth quarters of 2013, 2012 and 2011 and concluded that circumstances did not more likely than not indicate an impairment had occurred. For further information regarding goodwill, see Note 6, Goodwill.
	Historically, our policy was to perform the annual impairment test for goodwill at October 31 of each year, or more frequently if impairment indicators arose. During the fourth quarter of 2013, we changed the date of our annual goodwill impairment test to October 1 to better align with our annual and long-term planning and budgeting process. Accordingly, we believe this change in accounting principle is preferable. The change did not delay, accelerate, or avoid an impairment charge. This change in the annual goodwill impairment testing date was applied prospectively beginning on October 1, 2013 as we determined that it was impracticable to objectively determine projected cash flows and related valuation estimates that would have been used as of each October 1 of prior reporting periods without the use of hindsight.
	Other Intangible Assets
	Finite-lived intangible assets, primarily acquired patents and patent rights, are stated at cost, net of accumulated amortization. We recognize amortization expense for our finite-lived intangible assets on a straight-line basis over the estimated useful lives.
	Indefinite-lived intangible assets consist of acquired trademarks. Indefinite-lived intangible assets are stated at cost and are not amortized; instead, they are tested for impairment at least annually. We review our acquired trademarks for impairment in the fourth quarter of each year and when events or changes in circumstances indicate that the assets may be impaired. The fair value of trademarks is estimated using the relief from royalty approach, a standard form of discounted cash flow analysis used in the valuation of trademarks. If the carrying amount of trademarks exceeds the estimated fair value, we calculate impairment as the excess of carrying amount over the estimate of fair value. We tested our acquired trademarks for impairment in the fourth quarters of 2013, 2012 and 2011 and determined that no impairment was indicated. For further information regarding other intangible assets, see Note 7, Other Intangible Assets.
	Impairment of Long-Lived Assets
	Long-lived assets, including property, plant and equipment and finite-lived intangible assets, are evaluated for impairment when events or circumstances indicate the carrying value may be impaired. When such an event or condition occurs, we estimates the future undiscounted cash flows to be derived from the use and eventual disposition of the asset to determine whether a potential impairment exists. If the carrying value exceeds estimated future undiscounted cash flows, we record impairment expense to reduce the carrying value of the asset to its estimated fair value. No impairment charges were recorded in 2013, 2012 or 2011.
	Revenue Recognition
	Direct and Retail product sales and shipping revenues are recorded when products are shipped and title passes to customers. In most instances, Retail sales to customers are made pursuant to a sales contract that provides for transfer of both title and risk of loss to the customer upon our delivery to the carrier. For Direct sales, revenue is generally recognized when products are shipped. Revenue is recognized net of applicable sales incentives, such as promotional discounts, rebates and return allowances. We estimate the revenue impact of incentive programs based on the planned duration of the program and historical experience.
	Many Direct business customers finance their purchases through a third-party credit provider, for which we pay a commission or financing fee to the credit provider. Revenue for such transactions is recognized based on the sales price charged to the customer and the related commission or financing fee is included in Selling and Marketing expense.
	Sales Discounts and Returns Allowance
	Product sales and shipping revenues are reported net of promotional discounts and return allowances. We estimate the revenue impact of retail sales incentive programs based on the planned duration of the program and historical experience. If the amount of sales incentives is reasonably estimable, the impact of such incentives is recorded at the later of the time the customer is notified of the sales incentive or the time of the sale. We estimate our liability for product returns based on historical experience and record the expected obligation as a reduction of revenue. If actual return costs differ from previous estimates, the amount of the liability and corresponding revenue are adjusted in the period in which such costs occur. Activity in our sales discounts and returns allowance was as follows (in thousands):
		2013			2012			2011
	Balance, January 1	$	4,990		$	5,113		$	4,695
	Charges to reserve	13,345			11,730			10,735
	Reductions for sales discounts and returns	(14,229		)	(11,853		)	(10,317		)
	Balance, December 31	$	4,106		$	4,990		$	5,113
	Taxes Collected from Customers and Remitted to Governmental Authorities
	Taxes collected from customers and remitted to governmental authorities are recorded on a net basis and excluded from revenue.
	Shipping and Handling Fees
	Shipping and handling fees billed to customers are recorded gross and included in both revenue and cost of sales.
	Cost of Sales
	Cost of Sales primarily consists of: inventory costs; royalties paid to third parties; employment and occupancy costs of warehouse and distribution facilities, including depreciation of improvements and equipment; transportation expenses; product warranty expenses; distribution information systems expenses; and allocated expenses for shared administrative functions.
	Product Warranty Obligations
	Our products carry limited, defined warranties for defects in materials or workmanship which, according to their terms, generally obligate us to pay the costs of supplying and shipping replacement parts to customers and, in certain instances, pay for labor and other costs to service products. Outstanding product warranty periods range from sixty days to, in limited circumstances, the lifetime of certain product components. We record a liability at the time of sale for the estimated costs of fulfilling future warranty claims. If necessary, we adjust the liability for specific warranty-related matters when they become known and are reasonably estimable. Estimated warranty expense is included in Cost of Sales, based on historical warranty claim experience and available product quality data. Warranty expense is affected by the performance of new products, significant manufacturing or design defects not discovered until after the product is delivered to the customer, product failure rates, and higher or lower than expected repair costs. If warranty expense differs from previous estimates, or if circumstances change such that the assumptions inherent in previous estimates are no longer valid, the amount of product Warranty Obligations is adjusted accordingly.
	Litigation and Loss Contingencies
	From time to time, we may be involved in various claims, lawsuits and other proceedings. These legal and tax proceedings involve uncertainty as to the eventual outcomes and losses which may be realized when one or more future events occur or fail to occur. We record expenses for litigation and loss contingencies as a component of General and Administrative expense when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. When a loss contingency is not both probable and estimable, we do not establish an accrued liability. However, if the loss (or an additional loss in excess of the accrual) is at least a reasonable possibility and material, then we disclose an estimate of the possible loss or range of loss, if such estimate can be made, or disclose that an estimate cannot be made.
	Advertising and Promotion
	We expense our advertising and promotion costs as incurred. Production costs of television advertising commercials are recorded as prepaid expenses until the initial broadcast, at which time such costs are expensed. Advertising and promotion costs are included in Selling and Marketing expenses. Total advertising and promotion expenses were $35.8 million, $30.9 million and $28.6 million for the years ended December 31, 2013, 2012 and 2011, respectively. Prepaid advertising and promotion costs were $2.2 million and $1.3 million as of December 31, 2013 and 2012, respectively.
	Research and Development
	Internal research and development costs, which primarily consist of salaries and wages, employee benefits, expenditures for materials, and fees to use licensed technologies, are expensed as incurred. Third party research and development costs for products under development or being researched, if any, are expensed as the contracted work is performed.
Income Taxes
We account for income taxes based on the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to be in effect when the temporary differences are expected to be included, as income or expense, in the applicable tax return. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period of the enactment. Valuation allowances are provided against deferred income tax assets if we determine it is more likely than not that such assets will not be realized.
Unrecognized Tax Benefits
We recognize a tax benefit from an uncertain tax position when it is more likely than not that the position will be sustained based on the technical merits of the position upon examination, including resolutions of any related appeals or litigation.
Foreign Currency Translation
We translate the accounts of our non-U.S. subsidiaries into U.S. dollars as follows: revenues, expenses, gains and losses are translated at weighted-average exchange rates during the year; and assets and liabilities are translated at the exchange rate on the balance sheet date. Translation gains and losses are reported in our Consolidated Balance Sheets as a component of Accumulated Other Comprehensive Income. In the fourth quarter of 2012, we substantially completed the liquidation of our investment in foreign subsidiaries formerly associated with the Commercial business. As a result, an accumulated translation adjustment of $6.2 million was removed from accumulated other comprehensive income and recognized as a gain of the discontinued operations.
Gains and losses arising from foreign currency transactions, including transactions between us and our non-U.S. subsidiaries, are recorded as a component of other income (expense) in our Consolidated Statements of Operations.
Fair Value of Financial Instruments
The carrying values of Cash and Cash Equivalents, Trade Receivables, Prepaid and Other Current Assets, Short-Term Notes Receivable, Trade Payables and Accrued Liabilities approximate fair value due to their short maturities.
We did not have any financial instruments that were recorded at fair value on a recurring basis at December 31, 2013 or 2012.
Stock-Based Compensation
We recognize stock-based compensation expense on a straight-line basis over the applicable vesting period, based on the grant-date fair value of the award. To the extent a stock-based award is subject to performance conditions, the amount of expense recorded in a given period, if any, reflects our assessment of the probability of achieving the performance targets.
Fair value of stock options is estimated using the Black-Scholes-Merton option valuation model; fair value of performance share unit awards is estimated using the binomial valuation model; fair value of restricted stock unit awards is based on the closing market price on the day preceding the grant.
Net Income Per Share
Basic per share amounts were computed using the weighted average number of common shares outstanding. Diluted per share amounts were calculated using the number of basic weighted average shares outstanding increased by dilutive potential common shares related to stock-based awards, as determined by the treasury stock method.
Related Party Transactions
In September 2010, we entered into an agreement to borrow $5.0 million from certain entities under common control of Sherborne Investors GP, LLC and its affiliates (collectively “Sherborne”). At the time, Sherborne was our largest shareholder and was controlled by Edward J. Bramson, our former Chairman and Chief Executive Officer, and Craig L. McKibben, a former member of our Board of Directors. We incurred interest expense of $0.4 million and $0.1 million with respect to such debt in 2011 and 2010, respectively. We repaid all amounts outstanding with respect to such debt in March 2012 and, accordingly, both the outstanding principal balance and amount of accrued interest expense as of December 31, 2013 and 2012 were zero.
New Accounting Pronouncements
ASU 2013-02
In February 2013, the FASB issued ASU No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of Accumulated Other Comprehensive Income (“AOCI”) by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. The adoption of ASU 2013-02 in January 2013 did not have any impact on our financial position, results of operations or cash flows.
ASU 2013-11
In July 2013, the FASB issued ASU No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” ASU 2013-11 amends the guidance related to the presentation of unrecognized tax benefits and allows for the reduction of a deferred tax asset for a net operating loss (“NOL”) 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. ASU 2013-11 is effective for annual and interim periods for fiscal years beginning after December 15, 2013, and early adoption is permitted. Since ASU 2013-11 relates only to the presentation of unrecognized tax benefits, we do not expect our adoption of ASU 2013-11 in January 2014 will have a material effect on our financial position, results of operations or cash flows.

	DISCONTINUED OPERATIONS
	On September 25, 2009, in light of continuing operating losses in our Commercial business and in order to focus exclusively on managing our Direct and Retail businesses, we committed to a plan for the complete divestiture of our Commercial business, which qualified for held-for-sale accounting treatment. The Commercial business is presented as Discontinued Operations in our Condensed Consolidated Statements of Operations for all periods.
	The disposal of the Commercial business assets was completed in April 2011. We reached substantial completion of asset liquidation at December 2012. However, we continue to have legal and accounting expenses as we work with authorities on final deregistration of certain European entities and product liability expenses associated with product previously sold into the Commercial channel. There was no revenue related to the Commercial business for the years ended December 31, 2013 or 2012.

	BORROWINGS
	Line of Credit
	We have a Credit Agreement (the "Loan Agreement") with Bank of the West that provides for a $15,750,000 maximum revolving secured credit line. The line of credit is available through March 31, 2015 for working capital, standby letters of credit and general corporate purposes. Borrowing availability under the Loan Agreement is subject to our compliance with certain financial and operating covenants at the time borrowings are requested. Standby letters of credit under the Loan Agreement are treated as a reduction of the available borrowing amount and are subject to covenant testing.
	The interest rate applicable to borrowings under the Loan Agreement is based on either, at our discretion, Bank of the West's base rate, a floating rate or LIBOR, plus an applicable margin based on certain financial performance metrics. Our borrowing rate was 1.67% as of December 31, 2013. The Loan Agreement contains customary covenants, including minimum fixed charge coverage ratio and leverage ratio, and limitations on capital expenditures, mergers and acquisitions, indebtedness, liens, dispositions, dividends and investments. The Loan Agreement also contains customary events of default. Upon an event of default, the lender has the option of terminating its credit commitment and accelerating all obligations under the Loan Agreement. Borrowings under the Loan Agreement are collateralized by substantially all of our assets, including intellectual property assets.
	As of December 31, 2013, we had no outstanding borrowings and $0.5 million in standby letters of credit issued under the Loan Agreement. As of December 31, 2013, we were in compliance with the financial covenants of the Loan Agreement and approximately $15.3 million was available for borrowing.
	Sherborne Note Payable
	On September 3, 2010, we entered into a Note Purchase Agreement (the “Purchase Agreement”) with certain entities (collectively, the “Sherborne Purchasers”) under common control of Sherborne Investors GP, LLC and its affiliates (collectively “Sherborne”). Sherborne was formerly our largest shareholder and is controlled by Edward J. Bramson, our former Chairman and Chief Executive Officer, and Craig L. McKibben, a former member of our Board of Directors.
	Pursuant to the Purchase Agreement, we issued to the Sherborne Purchasers $6.1 million in aggregate principal amount at maturity of Increasing Rate Senior Discount Notes (the “Notes”). The Notes had an original principal amount totaling $5.0 million and an original maturity date of December 31, 2012. On March 12, 2012, the maturity date of the Notes was automatically extended under certain terms of the Purchase Agreement to May 2, 2013.
	On July 19, 2011, beneficial interest in the Notes was assigned by the Sherborne Purchasers pro-rata to their respective investors in the manner permitted by the Purchase Agreement. Such assignment was made in connection with the resignation of Messrs. Bramson and McKibben from their respective positions with Nautilus on May 26, 2011, and the subsequent pro-rata distribution by certain Sherborne-affiliated entities to their respective investors of our common stock owned by such entities.
	We repaid all amounts outstanding under the Notes on March 30, 2012. If all of the Notes were paid on the original maturity date, the effective rate of interest over the term of the Purchase Agreement would have been approximately 8.7% per annum, which was the rate at which interest expense was accrued in periods preceding the repayment date. The actual effective rate of interest through the repayment date was approximately 6.4% per annum.

As a result of certain realization requirements of ASC 718, the table of deferred tax assets and liabilities shown above does not include certain deferred tax assets as of December 31, 2013, and December 31, 2012, that arose directly from tax deductions related to equity compensation greater than compensation recognized for financial reporting. Equity will be increased by $0.3 million if and when such deferred tax assets are ultimately realized. We use tax law ordering when determining when excess tax benefits have been realized.
In the second quarter of 2013, we evaluated the potential realization of our Deferred Income Tax Assets, considering both positive and negative evidence, including cumulative income or loss for the past three years and forecasted taxable income. As a result of this evaluation we concluded that, as of June 30, 2013, a majority of the existing valuation allowance on our domestic Deferred Income Tax Assets was no longer required. As of December 31, 2013, we maintain the same position as the previous quarter that the partial release of valuation allowance is still appropriate. Accordingly, an income tax benefit of $38.9 million was recorded during 2013 related to the reduction of our existing valuation allowance.
Further there was a total of $4.4 million of Deferred Income Tax Asset reversal related to the expiration of capital loss and certain state net operating loss carryforwards during the fourth quarter of 2013. Accordingly a corresponding amount of valuation allowance was reversed in the same quarter.
Evaluating the need for, and amount of, a valuation allowance for deferred tax assets often requires significant judgment and extensive analysis of all available evidence on a jurisdiction-by-jurisdiction basis. Such judgments require us to interpret existing tax law and other published guidance as applied to our circumstances. As part of this assessment, we consider both positive and negative evidence. The weight given to the potential effect of positive and negative evidence must be commensurate with the extent to which the strength of the evidence can be objectively verified. We generally consider the following, but are not limited to, objectively verified evidence to determine the likelihood of realization of the deferred tax assets:
•	Our current financial position and our historical results of operations for recent years. We generally consider cumulative pre-tax losses in the three-year period ending with the current quarter to be significant negative evidence regarding our future profitability. A pattern of objectively-measured recent financial reporting losses is heavily weighted as a source of negative evidence. Further, we also consider the historical and current financial trends in the recent years.
•	Sources of taxable income of the appropriate character. Future realization of deferred tax assets is dependent on projected taxable income of the appropriate character from our continuing operations. Future reversals of existing temporary differences are heavily-weighted sources of objectively verifiable positive evidence. Projections of future taxable income exclusive of reversing temporary differences are a source of positive evidence only when the projections are combined with a history of recent profits and current financial trends and can be reasonably estimated.
•	Carryback and carryforward periods available. The long carryback and carryforward periods permitted under the tax law are objectively verified positive evidence.
•	Tax planning strategies. Tax planning strategies can be, depending on their nature, heavily-weighted sources of objectively verifiable positive evidence when the strategies are available and can be reasonably executed. We consider tax planning strategies only if they are feasible and justifiable considering our current operations and our strategic plan. Tax planning strategies, if executed, may accelerate the recovery of a deferred tax asset so the tax benefit of the deferred tax asset can be carried back.
During 2008, we determined that it was no longer more likely than not that the tax benefits from the existing U.S. deferred tax assets would be realized due to the substantial amount of the cumulative accounting losses realized in the recent years in the U.S. and the large taxable losses incurred in the U.S. in 2007 and 2008. Accordingly, we established a full valuation allowance against our U.S. net deferred tax assets in 2008.
Each quarter, we assess the total weight of positive and negative evidence and re-evaluate whether any adjustments or release of all or any portion of valuation allowance is appropriate. In our assessment during the second quarter of 2013, we heavily weighted the positive evidence of 1) cumulative profits realized in recent years combined with the upward financial trends of current periods; and 2) future realization of the existing U.S. deferred tax assets. Given our recent improved financial performance along with the sustained cumulative accounting profit, we projected a positive forecasted taxable income in the U.S. during the second quarter of 2013. Accordingly, based on our review of the objective evidence and our detailed analysis during the second quarter of 2013, we determined that a portion of our U.S. domestic valuation allowance was no longer required.
Of the remaining valuation allowance, $4.1 million relates to certain domestic loss and other credit carryforwards that we may not be able to utilize primarily due to their shorter remaining carryforward periods and $8.8 million relates to foreign net operating loss carryfowards. Should it be determined in the future that it is more likely than not that our domestic Deferred Income Tax Assets will be realized, an additional valuation allowance would be released during the period in which such an assessment is made. There have been no material changes to our foreign operations since December 31, 2012 and, accordingly, we maintain our existing valuation allowance on foreign Deferred Income Tax Assets in such jurisdictions at December 31, 2013.
Income Tax Carryforwards
As of December 31, 2013, we had the following income tax carryforwards (in millions):
			Amount				Expires in
Net operating loss carryforwards:
	U.S. Federal		$	64.4			2029 - 2031
	U.S. State		98.3				2014 - 2031
	Germany		11.2				Indefinite

Income tax credit carryforwards:
	U.S. Federal		2.9				2018 - 2033
	U.S. State		0.4				2019 - 2022
The timing and manner in which we are permitted to utilize our net operating loss carryforwards may be limited by Internal Revenue Code Section 382, Limitation on Net Operating Loss Carry-forwards and Certain Built-in-Losses Following Ownership Change.
Unrecognized Tax Benefits
Following is a reconciliation of gross unrecognized tax benefits from uncertain tax positions, excluding the impact of penalties and interest (in thousands):

Lapses of statutes of limitations	(314		)		(874		)		(56		)
Unrecognized tax benefits, end of year	$	1,964			$	2,530			$	4,376
Of the $2.0 million of gross unrecognized tax benefits from uncertain tax positions outstanding as of December 31, 2013, $1.6 million would affect our effective tax rate if recognized.
We recognize tax-related interest and penalties as a component of income tax expense. We had $1.6 million cumulative liability for interest and penalties related to uncertain tax positions for both years 2013 and 2012.
Our U.S. federal income tax returns for 2009 through 2013 are open to review by the U.S. Internal Revenue Service. Our state income tax returns for 2006 through 2013 are open to review, depending on the respective statute of limitation in each state. In addition, we file income tax returns in several non-U.S. jurisdictions with varying statutes of limitation.
As of December 31, 2013, we believe it is reasonably likely that, within the next 12 months, $0.1 million of previously unrecognized tax benefits related to certain U.S. and non-U.S. filing positions will be recognized as statutes of limitation expire.

	STOCK-BASED COMPENSATION
	2005 Long-Term Incentive Plan
	Our 2005 Long-Term Incentive Plan (the “2005 Plan”), which is administered by the Compensation Committee of the Board of Directors, authorizes us to grant various types of stock-based awards including: stock options, stock appreciation rights, restricted stock, restricted stock units ("RSUs") and performance stock units ("PSUs"). Stock options granted under the 2005 Plan shall not have an exercise price less than the fair market value of our common stock on the date of the grant. The exercise price of a stock option or stock appreciation right may not be reduced without shareholder approval. Stock options generally vest over periods of three or four years of continuous service, commencing on the date of grant. Stock options granted under the 2005 Plan have a seven-year contractual term. Stock options granted under the preceding plan expire after ten years.
	Upon adoption, there were approximately 4.0 million shares available for issuance under the 2005 Plan. The number of shares available for issuance is increased by any shares of common stock which were previously reserved for issuance under our preceding stock option plan, and were not subject to grant on June 6, 2005, or as to which the stock-based compensation award is forfeited on or after June 6, 2005. The number of shares available for issuance is reduced by (i) two shares for each share delivered in settlement of any stock appreciation rights, for each share of restricted stock, and for each stock unit or performance unit award, and (ii) one share for each share delivered in settlement of a stock option award. In no event shall more than 1.0 million aggregate shares of common stock subject to stock options, stock appreciation rights, restricted stock or performance stock unit awards be granted to any one participant in any one year under the 2005 Plan. At December 31, 2013, we had 3.8 million shares available for future grant under our 2005 Plan and we had 5.1 million shares of our common stock reserved for future issuance pursuant to the 2005 Plan and our previous plan.

	PSU Activity
	In April 2010, we granted PSU awards covering a total of 146,000 shares of our common stock to key members of our executive team. The PSUs were subject to both time-based vesting (one-third annually over three years) and achievement of a stock price target of two times the grant date price. If, over the three-year period, the stock price did not close at or above two times the grant date price over any 20 of 30 consecutive days, the entire award would have been forfeited. Compensation expense for PSUs is recognized over the estimated requisite service period based on the number of PSUs ultimately expected to vest. These awards vested in full over the three-year vesting period.
	In February and August 2012, we granted PSU awards to certain executive officers covering a total of 82,000 shares of our common stock. The PSUs vest based on achievement of certain operating income and return on asset goals established for a three-year performance period. The number of PSUs that ultimately vest following conclusion of the performance period will be determined based on the level at which the financial goals are achieved. The number of PSUs that vest can range from 60% of the PSUs if minimum thresholds are achieved to a maximum of 150%.
	In May 2013, we granted PSU awards to certain of our executive officers covering a total of 24,500 shares of our common stock. The PSUs vest based on achievement of certain operating income and return on asset goals established for a three-year performance period. The number of shares vesting under the PSU awards following conclusion of the performance period will be determined based on the level at which the financial goals are achieved. The number of shares vesting can range from 60% of the PSU awards if minimum thresholds are achieved to a maximum of 150%.

	As of December 31, 2013, unrecognized compensation expense for outstanding, but unvested stock-based awards was $0.5 million, which is expected to be recognized over a weighted average period of 1.5 years.
	Assumptions used in calculating the fair value of stock-option grants were as follows:
		Year Ended December 31,
		2013		2012			2011
Dividend yield	—	%	—	%		—	%
Risk-free interest rate	0.9	%	0.9	%		1.5	%
Expected life (years)	4.75		4.75			4.75
Expected volatility	89	%	92	%		92	%
Expected dividend yield is based on our current expectation that no dividend payments will be made in future periods.
Risk-free interest rate is the U.S. Treasury zero-coupon rate, as of the grant date, for issues having a term approximately equal to the expected life of the stock option.
Expected life is the period of time over which stock options are expected to remain outstanding. We calculate expected term based on the average of the sum of the vesting periods and the full contractual term.
Expected volatility is the percentage amount by which the price of our common stock is expected to fluctuate annually during the estimated expected life for stock options. Expected price volatility is calculated using historical daily closing prices over a period matching the weighted-average expected life, as management believes such changes are the best indicator of future volatility.
We estimate future forfeitures, at the time of grant and in subsequent periods, based on historical turnover rates, previous forfeiture experience and changes in the business or key personnel that would suggest future forfeitures may differ from historical data. We recognize compensation expense for only those stock options and other stock-based awards that are expected to vest. We reevaluate estimated forfeitures each quarter and, if applicable, recognize a cumulative effect adjustment in the period of the change if the revised estimate of the impact of forfeitures differs significantly from the previous estimate.

	We have two reportable segments - Direct and Retail. Contribution is the measure of profit or loss, defined as net sales less product costs and directly attributable expenses. Directly attributable expenses include Selling and Marketing expenses, General and Administrative expenses, and Research and Development expenses that are directly related to segment operations. Segment assets are those directly assigned to an operating segment's operations, primarily Accounts Receivable, Inventories and Intangible Assets. Unallocated assets primarily include shared information technology infrastructure, distribution centers, corporate headquarters, Prepaids and Other Current Assets, Deferred Income Tax Assets and Other Assets.

	We lease property and equipment under non-cancelable operating leases which, in the aggregate, extend through 2019.

	Guarantees, Commitments and Off-Balance Sheet Arrangements
	As of December 31, 2013, we had approximately $0.5 million in standby letters of credit with certain vendors with expiration dates through 2014.
	We have long lead times for inventory purchases and, therefore, must secure factory capacity from our vendors in advance. As of December 31, 2013, we had approximately $8.8 million in non-cancelable market-based purchase obligations, primarily for inventory purchases expected to be received within the next twelve months. Purchase obligations can vary from quarter-to-quarter and versus the same period in prior years due to a number of factors, including the amount of products that are shipped directly to Retail customer warehouses versus through Nautilus warehouses.
	In the ordinary course of business, we enter into agreements that require us to indemnify counterparties against third-party claims. These may include: agreements with vendors and suppliers, under which we may indemnify them against claims arising from use of their products or services; agreements with customers, under which we may indemnify them against claims arising from their use or sale of our products; real estate and equipment leases, under which we may indemnify lessors against third-party claims relating to the use of their property; agreements with licensees or licensors, under which we may indemnify the licensee or licensor against claims arising from their use of our intellectual property or our use of their intellectual property; and agreements with parties to debt arrangements, under which we may indemnify them against claims relating to their participation in the transactions.
	The nature and terms of these indemnification obligations vary from contract to contract, and generally a maximum obligation is not stated within the agreements. We hold insurance policies that mitigate potential losses arising from certain types of indemnification obligations. Management does not deem these obligations to be significant to our financial position, results of operations or cash flows and, therefore, no related liabilities were recorded as of December 31, 2013.
	Legal Matters
	From time to time, we may be involved in various claims, lawsuits and other proceedings. These legal and tax proceedings involve uncertainty as to the eventual outcomes and losses which may be realized when one or more future events occur or fail to occur.
	Litigation and jury verdicts are, to some degree, inherently unpredictable, and although we have determined that a loss is not probable in connection with any current legal proceeding, it is reasonably possible that a loss may be incurred in connection with proceedings to which we are a party. Assessment of whether incurrence of a loss is probable, or a reasonable possibility, in connection with a particular proceeding, and estimation of the loss, or a range of loss, involves complex judgments and numerous uncertainties. Management is unable to estimate a range of reasonably possible losses related to litigation in its early stages, especially when the damages sought are indeterminate, or the legal and factual basis for the relevant claims have not been developed with specificity, as such zero liability is recorded as of December 31, 2013.
	We regularly monitor our estimated exposure to these contingencies and, as additional information becomes known, may change our estimates accordingly. We evaluate, on a quarterly basis, developments in legal proceedings, investigations or claims that could affect the amount of any accrual, as well as any developments that would make a loss probable or reasonably possible, and whether the amount of a probable or reasonably possible loss is estimable. Among other factors, we evaluate the advice of internal and external counsel, the outcomes from similar litigation, current status of the lawsuits (including settlement initiatives), legislative developments and other factors. Due to the numerous variables associated with these judgments and assumptions, both the precision and reliability of the resulting estimates of the related loss contingencies are subject to substantial uncertainties.

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Discontinued Operation	'
	Discontinued Operations
	Results from discontinued operations relate to the disposal of our former Commercial business, which began in 2009 and was completed in April 2011. We reached substantial completion of asset liquidation at December 31, 2012. However, we continue to have legal and accounting expenses as we work with authorities on final deregistration of each entity and product liability expenses associated with product previously sold into the Commercial channel.
Use of estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities in the financial statements. Our most significant estimates relate to the following:
	•	Revenue recognition;
	•	Sales discounts and allowances;
	•	Goodwill and other long-term asset valuation;
	•	Product warranty obligations;
	•	Valuation of excess and obsolete inventory;
	•	Litigation and loss contingencies;
	•	Deferred tax assets and the related valuation allowance; and
	•	Unrecognized tax benefits.
	Actual results could differ from our estimates.
Concentrations of risk	'
	Concentrations
	Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash held in bank accounts in excess of federally-insured limits and trade receivables. Trade receivables are generally unsecured and therefore collection is affected by the economic conditions in each of our principal markets.
	We rely on third-party contract manufacturers in Asia for substantially all of our products and for certain product engineering support. Business operations could be disrupted by natural disasters, difficulties in transporting products from non-U.S. suppliers, as well as political, social or economic instability in the countries where contract manufacturers or their vendors or customers conduct business. While any such contract manufacturing arrangement could be replaced over time, the temporary loss of the services of any primary contract manufacturer could delay product shipments and cause a significant disruption in our operations.
	We derive a significant portion of our Net Sales from a small number of our Retail customers. A loss of business from one or more of these large customers, if not replaced with new business, would negatively affect our operating results and cash flows. In 2013, 2012 and 2011, one customer accounted for more than 10%, but less than 15%, of our Net Sales.
Cash, cash equivalents and restricted cash	'
	Cash and Cash Equivalents
	All highly liquid investments with maturities of three months or less at purchase are considered to be cash equivalents. As of December 31, 2013 and 2012, cash and cash equivalents consisted entirely of cash.
Inventories	'
	Inventories
	Inventories are stated at the lower of cost or market, with cost determined based on the first-in, first-out method. We establish inventory allowances for excess, slow-moving and obsolete inventory based on inventory levels, expected product life and forecasted sales. Inventories are written down to market value based on historical demand, competitive factors, changes in technology and product lifecycles.
Property, plant and equipment	'
	Property, Plant and Equipment
	Property, plant and equipment is stated at cost, net of accumulated depreciation. Improvements or betterments which add new functionality or significantly extend the life of an asset are capitalized. Expenditures for maintenance and repairs are expensed as incurred. The cost of assets retired, or otherwise disposed of, and the related accumulated depreciation, are removed from the accounts at the time of disposal. Gains and losses resulting from asset sales and dispositions are recognized in the period in which assets are disposed. Depreciation is recognized, using the straight-line method, over the lesser of the estimated useful lives of the assets or, in the case of leasehold improvements, the lease term, including renewal periods if we expect to exercise our renewal options. Depreciation on computer equipment, machinery and equipment and furniture and fixtures is determined based on estimated useful lives, which generally range from three-to-five years.
Goodwill	'
	Goodwill
	Goodwill consists of the excess of acquisition costs over the fair values of net assets acquired in business combinations. We review goodwill for impairment in the fourth quarter of each year and when events or changes in circumstances indicate that the carrying amount may be impaired. For this purpose, goodwill is evaluated at the reporting unit level. Our goodwill is an asset of our Direct reporting unit. We performed a qualitative assessment of goodwill in the fourth quarters of 2013, 2012 and 2011 and concluded that circumstances did not more likely than not indicate an impairment had occurred. For further information regarding goodwill, see Note 6, Goodwill.
Other intangible assets	'
	Other Intangible Assets
	Finite-lived intangible assets, primarily acquired patents and patent rights, are stated at cost, net of accumulated amortization. We recognize amortization expense for our finite-lived intangible assets on a straight-line basis over the estimated useful lives.
	Indefinite-lived intangible assets consist of acquired trademarks. Indefinite-lived intangible assets are stated at cost and are not amortized; instead, they are tested for impairment at least annually. We review our acquired trademarks for impairment in the fourth quarter of each year and when events or changes in circumstances indicate that the assets may be impaired. The fair value of trademarks is estimated using the relief from royalty approach, a standard form of discounted cash flow analysis used in the valuation of trademarks. If the carrying amount of trademarks exceeds the estimated fair value, we calculate impairment as the excess of carrying amount over the estimate of fair value. We tested our acquired trademarks for impairment in the fourth quarters of 2013, 2012 and 2011 and determined that no impairment was indicated. For further information regarding other intangible assets, see Note 7, Other Intangible Assets.
Impairment of long-lived assets	'
	Impairment of Long-Lived Assets
	Long-lived assets, including property, plant and equipment and finite-lived intangible assets, are evaluated for impairment when events or circumstances indicate the carrying value may be impaired. When such an event or condition occurs, we estimates the future undiscounted cash flows to be derived from the use and eventual disposition of the asset to determine whether a potential impairment exists. If the carrying value exceeds estimated future undiscounted cash flows, we record impairment expense to reduce the carrying value of the asset to its estimated fair value. No impairment charges were recorded in 2013, 2012 or 2011.
Revenue recognition	'
	Revenue Recognition
	Direct and Retail product sales and shipping revenues are recorded when products are shipped and title passes to customers. In most instances, Retail sales to customers are made pursuant to a sales contract that provides for transfer of both title and risk of loss to the customer upon our delivery to the carrier. For Direct sales, revenue is generally recognized when products are shipped. Revenue is recognized net of applicable sales incentives, such as promotional discounts, rebates and return allowances. We estimate the revenue impact of incentive programs based on the planned duration of the program and historical experience.
	Many Direct business customers finance their purchases through a third-party credit provider, for which we pay a commission or financing fee to the credit provider. Revenue for such transactions is recognized based on the sales price charged to the customer and the related commission or financing fee is included in Selling and Marketing expense.
Sales discounts and allowances	'
	Sales Discounts and Returns Allowance
	Product sales and shipping revenues are reported net of promotional discounts and return allowances. We estimate the revenue impact of retail sales incentive programs based on the planned duration of the program and historical experience. If the amount of sales incentives is reasonably estimable, the impact of such incentives is recorded at the later of the time the customer is notified of the sales incentive or the time of the sale. We estimate our liability for product returns based on historical experience and record the expected obligation as a reduction of revenue. If actual return costs differ from previous estimates, the amount of the liability and corresponding revenue are adjusted in the period in which such costs occur. Activity in our sales discounts and returns allowance was as follows (in thousands):
Taxes collected from customers and remitted to governmental authorities	'
	Taxes Collected from Customers and Remitted to Governmental Authorities
	Taxes collected from customers and remitted to governmental authorities are recorded on a net basis and excluded from revenue.
Shipping and handling fees	'
	Shipping and Handling Fees
	Shipping and handling fees billed to customers are recorded gross and included in both revenue and cost of sales.
Cost of sales	'
	Cost of Sales
	Cost of Sales primarily consists of: inventory costs; royalties paid to third parties; employment and occupancy costs of warehouse and distribution facilities, including depreciation of improvements and equipment; transportation expenses; product warranty expenses; distribution information systems expenses; and allocated expenses for shared administrative functions.
Product warranty obligations	'
	Product Warranty Obligations
	Our products carry limited, defined warranties for defects in materials or workmanship which, according to their terms, generally obligate us to pay the costs of supplying and shipping replacement parts to customers and, in certain instances, pay for labor and other costs to service products. Outstanding product warranty periods range from sixty days to, in limited circumstances, the lifetime of certain product components. We record a liability at the time of sale for the estimated costs of fulfilling future warranty claims. If necessary, we adjust the liability for specific warranty-related matters when they become known and are reasonably estimable. Estimated warranty expense is included in Cost of Sales, based on historical warranty claim experience and available product quality data. Warranty expense is affected by the performance of new products, significant manufacturing or design defects not discovered until after the product is delivered to the customer, product failure rates, and higher or lower than expected repair costs. If warranty expense differs from previous estimates, or if circumstances change such that the assumptions inherent in previous estimates are no longer valid, the amount of product Warranty Obligations is adjusted accordingly.
Litigation and loss contingencies	'
	Litigation and Loss Contingencies
	From time to time, we may be involved in various claims, lawsuits and other proceedings. These legal and tax proceedings involve uncertainty as to the eventual outcomes and losses which may be realized when one or more future events occur or fail to occur. We record expenses for litigation and loss contingencies as a component of General and Administrative expense when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. When a loss contingency is not both probable and estimable, we do not establish an accrued liability. However, if the loss (or an additional loss in excess of the accrual) is at least a reasonable possibility and material, then we disclose an estimate of the possible loss or range of loss, if such estimate can be made, or disclose that an estimate cannot be made.
Advertising and promotion	'
	Advertising and Promotion
	We expense our advertising and promotion costs as incurred. Production costs of television advertising commercials are recorded as prepaid expenses until the initial broadcast, at which time such costs are expensed. Advertising and promotion costs are included in Selling and Marketing expenses. Total advertising and promotion expenses were $35.8 million, $30.9 million and $28.6 million for the years ended December 31, 2013, 2012 and 2011, respectively. Prepaid advertising and promotion costs were $2.2 million and $1.3 million as of December 31, 2013 and 2012, respectively.
Research and development	'
	Research and Development
	Internal research and development costs, which primarily consist of salaries and wages, employee benefits, expenditures for materials, and fees to use licensed technologies, are expensed as incurred. Third party research and development costs for products under development or being researched, if any, are expensed as the contracted work is performed.
Income taxes	'
	Income Taxes
	We account for income taxes based on the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to be in effect when the temporary differences are expected to be included, as income or expense, in the applicable tax return. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period of the enactment. Valuation allowances are provided against deferred income tax assets if we determine it is more likely than not that such assets will not be realized.
	Unrecognized Tax Benefits
	We recognize a tax benefit from an uncertain tax position when it is more likely than not that the position will be sustained based on the technical merits of the position upon examination, including resolutions of any related appeals or litigation.
Foreign currency translation	'
	Foreign Currency Translation
	We translate the accounts of our non-U.S. subsidiaries into U.S. dollars as follows: revenues, expenses, gains and losses are translated at weighted-average exchange rates during the year; and assets and liabilities are translated at the exchange rate on the balance sheet date. Translation gains and losses are reported in our Consolidated Balance Sheets as a component of Accumulated Other Comprehensive Income. In the fourth quarter of 2012, we substantially completed the liquidation of our investment in foreign subsidiaries formerly associated with the Commercial business. As a result, an accumulated translation adjustment of $6.2 million was removed from accumulated other comprehensive income and recognized as a gain of the discontinued operations.
	Gains and losses arising from foreign currency transactions, including transactions between us and our non-U.S. subsidiaries, are recorded as a component of other income (expense) in our Consolidated Statements of Operations.
Fair value of financial instruments	'
	Fair Value of Financial Instruments
	The carrying values of Cash and Cash Equivalents, Trade Receivables, Prepaid and Other Current Assets, Short-Term Notes Receivable, Trade Payables and Accrued Liabilities approximate fair value due to their short maturities.
Net Income Per Share	'
	Net Income Per Share
	Basic per share amounts were computed using the weighted average number of common shares outstanding. Diluted per share amounts were calculated using the number of basic weighted average shares outstanding increased by dilutive potential common shares related to stock-based awards, as determined by the treasury stock method.
Share-based based compensation	'
	Stock-Based Compensation
	We recognize stock-based compensation expense on a straight-line basis over the applicable vesting period, based on the grant-date fair value of the award. To the extent a stock-based award is subject to performance conditions, the amount of expense recorded in a given period, if any, reflects our assessment of the probability of achieving the performance targets.
	Fair value of stock options is estimated using the Black-Scholes-Merton option valuation model; fair value of performance share unit awards is estimated using the binomial valuation model; fair value of restricted stock unit awards is based on the closing market price on the day preceding the grant.
New Accounting Pronouncements	'
	New Accounting Pronouncements
	ASU 2013-02
	In February 2013, the FASB issued ASU No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of Accumulated Other Comprehensive Income (“AOCI”) by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. The adoption of ASU 2013-02 in January 2013 did not have any impact on our financial position, results of operations or cash flows.
	ASU 2013-11
	In July 2013, the FASB issued ASU No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” ASU 2013-11 amends the guidance related to the presentation of unrecognized tax benefits and allows for the reduction of a deferred tax asset for a net operating loss (“NOL”) 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. ASU 2013-11 is effective for annual and interim periods for fiscal years beginning after December 15, 2013, and early adoption is permitted. Since ASU 2013-11 relates only to the presentation of unrecognized tax benefits, we do not expect our adoption of ASU 2013-11 in January 2014 will have a material effect on our financial position, results of operations or cash flows.
