Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The accompanying consolidated financial statements and footnotes have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") and with the instructions to Form 10-K and Regulation S-X. The Company's annual reporting period is based on a calendar year.
	Summary of Significant Accounting Policies
	Principles of Consolidation.    The consolidated financial statements include the accounts of Holdings and all of its subsidiaries. All inter-company transactions have been eliminated in consolidation. The Company has no relationships with unconsolidated entities or financial partnerships, commonly referred to as variable interest entities.
	Use of Estimates.    The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. Accordingly, these estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. On a regular basis, management reviews its estimates utilizing currently available information, changes in facts and circumstances, historical experience and reasonable assumptions. After such reviews and if deemed appropriate, those estimates are adjusted accordingly. Actual results could differ from those estimates.
	Cash and Cash Equivalents.    The Company considers cash and cash equivalents to include all cash and liquid deposits and investments with an original maturity of three months or less. The majority of payments due from banks for third-party credit and debit cards process within 24 to 72 hours, and are classified as cash equivalents.
	Receivables, net.    The Company extends credit terms for sales of product to its franchisees and, to a lesser extent, various third-party customers. Receivables consist principally of trade receivables of $133.4 million and $140.8 million at December 31, 2014 and 2013, respectively, and include unpaid invoices for product sales, franchisee royalties and lease payments. The Company monitors the financial condition of the Company's franchisees and other third-party customers and establishes an allowance for doubtful accounts for balances estimated to be uncollectible. In addition to considering the aging of receivable balances and assessing the financial condition of the Company's franchisees, the Company considers each domestic franchisees' inventory and fixed assets, which the Company can use as collateral in the event of a default by the franchisee. An allowance for international franchisees is calculated based on unpaid, non-collateralized amounts associated with their receivable balance. The allowance for doubtful accounts was $6.2 million and $1.9 million at December 31, 2014 and 2013, respectively. The current year allowance includes the impact of the international franchise receivable reserve detailed below.
	Inventories.    Inventory components consist of raw materials, work-in-process, finished product and packaging supplies. Inventories are stated at the lower of cost or market on a first in/first out basis ("FIFO"). The Company regularly reviews its inventory levels in order to identify slow moving and short dated products, expected length of time for product to be sold and future expiring product and adjusts the carrying value for such inventory to estimated net realizable value.
	Property, Plant and Equipment.    Property, plant and equipment expenditures are recorded at cost. Depreciation and amortization are recognized using the straight-line method over the estimated useful life of the property. The estimated useful lives range from one to fifteen years across all asset classes with the exception of buildings, which are depreciated over thirty years and building improvements, which are depreciated over their estimated useful life or the remaining useful life of the related building, whichever period is shorter. Furniture and fixtures are depreciated over three to fifteen years, and machinery and equipment is generally depreciated over ten years. Computer equipment and software costs are generally depreciated over three to five years. Improvements to retail leased premises are depreciated over the estimated useful life of the improvements or the related leases including renewals that are reasonably assured, whichever period is shorter.
	Expenditures that materially increase the value or clearly extend the useful life of property, plant and equipment are capitalized in accordance with the policies outlined above. Repair and maintenance costs incurred in the normal operations of business are expensed as incurred. Gains/losses from the sale of property, plant and equipment are recognized in current operations.
	Goodwill and Intangible Assets.    Goodwill represents the excess of purchase price over the fair value of identifiable net assets of businesses, including franchisees, acquired by the Company. Goodwill and intangible assets with indefinite useful lives are not amortized, but instead are tested for impairment at least annually or more frequently if events or changes in circumstances indicate that the assets might be impaired. The Company completes its annual impairment test in the fourth quarter.
	Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. The Company performs a qualitative assessment to determine whether it is "more likely than not" that the fair value of the reporting unit is less than its carrying value. The qualitative factors considered are general macroeconomic conditions, industry specific conditions, historical performance, and future outlooks. If it is concluded that it is "more likely than not" that the fair value of a reporting unit is less than its carrying value, the Company is required to perform a quantitative goodwill impairment test.
	The impairment test for intangible assets with indefinite useful lives consists of a comparison of the fair values of the intangible assets to their carrying values. If the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Similar to goodwill, the Company first performs a qualitative assessment to determine whether it is necessary to perform the quantitative impairment test.
	There have been no goodwill or indefinite-lived intangible asset impairments recorded to date. See Note 5, "Goodwill, Brands, and Other Intangible Assets, Net."
	Long-lived Assets.    The Company reviews the carrying value of property and equipment and amortizable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. Factors the Company considers important that may trigger an impairment review include significant changes in the manner of its use of assets, significant negative industry or economic trends, underperforming stores and store closings. These reviews may include an analysis of the current operations and capacity utilization, in conjunction with an analysis of the markets in which the businesses are operating. When an impairment review is considered necessary, a comparison is performed of the undiscounted projected cash flows from the use and eventual disposition of the asset group to the net book value of the related asset group. If it is determined that the carrying value of the asset group may not be recoverable, a charge to adjust the carrying value of the long-lived assets to estimated fair value may be required.
	Revenue Recognition.    The Company operates predominantly as a retailer, through company-owned stores, franchise stores and its e-commerce businesses and to a lesser extent through manufacturing and wholesale operations.
	The Retail segment recognizes revenue at the point of sale. Gross revenues are netted by actual customer returns and an allowance for expected customer returns. The Company records a reserve for expected customer returns based on management's estimate, which is derived from historical return data and expectations of future return volume. Revenue is deferred on sales of the Company's Gold Cards and subsequently amortized over the membership period, in order to match the discounts associated with the Gold Card program. During 2013, the Company completed the nationwide rollout of the Gold Card Member Pricing model, which evolved the Gold Card from a 20% discount the first week of the month to an everyday variable discount based on our Member Pricing model, for an annual fee.
	The Company also sells gift cards to its customers. Revenue from gift cards is recognized when the gift card is redeemed. These gift cards do not have expiration dates. Based upon historical redemption rates, a small percentage of gift cards will never be redeemed, referred to as "breakage." The Company recognizes gift card breakage revenue when the likelihood of redemption becomes remote and amounts are not escheatable.
	The Franchise segment generates revenues through product sales to franchisees, royalties and franchise fees. These revenues are netted by actual franchisee returns and an allowance for projected returns. The franchisees purchase a majority of the products they sell from the Company at wholesale prices. Revenue on product sales to franchisees is recognized when risk of loss, title and insurable risks have transferred to the franchisee. Franchise fees are paid in advance, deferred and recognized by the Company at the time of a franchise store opening. Franchise royalties are earned based on a percentage of the franchisees' sales and recognized in the period the franchisees' sales occur.
	The Manufacturing/Wholesale segment sells product to the Company's other segments and third-party customers. Revenue is recognized when risk of loss, title and insurable risks have transferred to the customer, net of estimated returns and allowances.
	Cost of Sales.    The Company purchases products directly from third-party manufacturers and manufactures its own products. The Company's cost of sales includes product costs, costs of warehousing and distribution and occupancy costs.
	Vendor Allowances.    The Company receives allowances from various vendors based on either sales or purchase volumes. As the right of offset exists under these arrangements, credit earned under both arrangements are recorded as a reduction in the vendors' accounts payable balances on the balance sheet and represent the estimated amounts due to the Company under the rebate provisions of such contracts. The corresponding rebate income is recorded as a reduction to cost of sales based on inventory turnover and was $89.5 million, $92.6 million and $81.5 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Research and Development.    Research and development costs arising from internally generated projects are expensed by the Company as incurred. The Company recognized $1.2 million, $1.4 million and $1.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. These costs are classified as "Other selling, general, and administrative" in the accompanying audited consolidated statements of income.
	Advertising Expenditures.    The Company recognizes advertising, promotion and marketing program costs the first time the advertising takes place, with the exception of the costs of producing advertising, which are expensed as incurred during production. The Company administers national advertising funds on behalf of its franchisees. In accordance with the franchisee contracts, the Company collects advertising fees from the franchisees and utilizes the proceeds to coordinate various advertising and marketing campaigns. The Company recognized advertising expense of $70.5 million, $67.2 million and $62.3 million for the years ended December 31, 2014, 2013 and 2012, respectively, net of approximately $15.9 million, $15.4 million and $14.4 million received from the national advertising fund derived from the Company's franchisees.
	Leases.    The Company has various operating leases for company-owned and franchise store locations, distribution centers, and equipment. Leases generally include amounts relating to base rental, percent rent and other charges such as common area maintenance fees and real estate taxes. Periodically, the Company receives varying amounts of reimbursements from landlords to compensate the Company for costs incurred in the construction of stores. These reimbursements are amortized by the Company as an offset to rent expense over the life of the related lease. The Company determines the period used for the straight-line rent expense for leases with option periods and conforms it to the term used for amortizing improvements.
	The Company leases an approximately 300,000 square foot-facility in Greenville, South Carolina where the majority of its proprietary products are manufactured. The Company also leases a 630,000 square foot complex located in Anderson, South Carolina, for packaging, materials receipt, lab testing, warehousing, and distribution. Both the Greenville and Anderson facilities are leased on a long-term basis pursuant to "fee-in-lieu-of-taxes" arrangements with the counties in which the facilities are located, but the Company retains the right to purchase each of the facilities at any time during the lease for $1.00, subject to a loss of tax benefits. As part of a tax incentive arrangement, the Company assigned the facilities to the counties and leases them back under operating leases. The Company leases the facilities from the counties where located, in lieu of paying local property taxes. Upon exercising its right to purchase the facilities back from the counties, the Company will be subject to the applicable taxes levied by the counties. As a result, the original cost basis of the facilities remains on the balance sheet and continues to be depreciated.
	Contingencies.    The Company accrues a loss contingency if it is probable and can be reasonably estimated (including the satisfaction of this criteria for matters that exist as of the balance sheet date based on information which becomes available subsequent to the date of the financial statements but before the financial statements are issued). If both of the conditions above are not met, disclosure is made when there is at least a reasonable possibility that a loss contingency has been incurred. If both of the conditions above are met, disclosure is made when there is at least a reasonable possibility that an additional loss has been incurred above what is recognized as a liability in the financial statements. As facts concerning contingencies evolve and become known, management reassesses the likelihood of probable loss and makes appropriate adjustments to its financial statements.
	Pre-Opening Expenditures.    The Company recognizes the cost associated with the opening of new stores as incurred. These costs are charged to expense and are not material for the periods presented. Franchise store pre-opening costs are incurred by the franchisees.
	Income Taxes. The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities result from (i) the future tax impact of temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and (ii) differences between the recorded value of assets acquired in business combinations accounted for as purchases for financial reporting purposes and their corresponding tax bases. Deferred income tax assets are reduced by a valuation allowance if it is more likely than not that some portion of the deferred income tax asset will not be realized.
	The Company recognizes the tax benefit from an uncertain tax position only if it is at least more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position. The amount of the tax benefit that is recognized is measured as the largest amount of benefit that is more likely than not to be realized upon effective settlement. The Company classifies interest and penalties accrued in connection with unrecognized tax benefits as income tax expense in its consolidated statements of income.
	Refer to Note 4, "Income Taxes," for more information.
	Self-Insurance.    The Company has procured insurance for: (1) general liability; (2) product liability; (3)  directors and officers liability; (4) network security and privacy liability; (5) property losses; (6) workers' compensation; and (7) various other areas. The Company is self-insured for: (1) medical benefits; (2) physical damage to the Company's vehicles for field personnel use; and (3) physical damages that may occur at the company-owned store locations. The Company is not insured for certain property and casualty risks due to the Company's assessment of frequency and severity of a loss, the cost of insurance and the overall risk analysis.
	The Company carries product liability insurance with a retention of $4.0 million per claim with an aggregate cap on retained losses of $10.0 million. The Company carries general liability insurance with retention of $250,000 per claim with an aggregate cap on retained losses of $1.0 million. The majority of the Company's workers' compensation and auto insurance policies are in deductible/retrospective plans. The Company reimburses the applicable insurance company for the workers' compensation and auto liability claims, subject to a $250,000 and $100,000 loss limit per claim, respectively.
	As part of the medical benefits program, the Company contracts with national service providers to provide benefits to its employees for all medical, dental, vision and prescription drug services. The Company then reimburses these service providers as claims are processed from Company employees. The Company maintains a specific stop loss provision of $500,000 per individual per plan year with a maximum lifetime benefit limit of $2.0 million per individual. The Company has no additional liability once a participant exceeds the $2.0 million ceiling. The Company's liability for medical claims is included as a component of accrued benefits in Note 7, "Deferred Revenue and Other Current Liabilities," and was $2.9 million and $2.0 million as of December 31, 2014 and 2013, respectively.
	The Company's self-insurance liabilities, including the estimated loss accruals for claims incurred but not paid, are determined by taking into account historical claims payment results and known trends such as claims frequency and claims severity. Management makes estimates, judgments, and assumptions with respect to the use of these calculations, including but not limited to, estimated lag time to report and pay claims, average cost per claim, network utilization rates, network discount rates, and other factors.
	Stock-based Compensation.    The Company utilizes the Black-Scholes model to calculate the fair value of stock option awards (herein referred to as "option awards"). The grant-date fair value of the Company's restricted stock awards, time vesting restricted stock units, and performance vesting restricted stock units (collectively herein referred to as "stock awards") are based on the closing price for a share of the Company's common stock on the New York Stock Exchange (the "NYSE") on the grant date. The resulting compensation cost is recognized in the Company's financial statements over the applicable vesting period for the relevant award, net of expected forfeitures.
	Earnings Per Share.    Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding adjusted for the additional dilutive effect of unexercised option awards and unvested stock awards.
	Foreign Currency.    For all foreign operations, the functional currency is the local currency. Assets and liabilities of those operations, denominated in foreign currencies, are translated into U.S. dollars using period-end exchange rates, and income and expenses are translated using the average exchange rates for the reporting period. At December 31, 2014 and 2013, foreign currency is the only component of accumulated other comprehensive income on the consolidated balance sheets. Gains or losses resulting from foreign currency transactions are included in the consolidated statements of income and were not material for the fiscal years ended December 31, 2014, 2013 and 2012.
	Transaction and restructuring related costs.    Restructuring related costs are recorded in the period in which the liability is incurred. Additionally, any change in the expected liability is recorded in the period the change in estimate occurs. In October 2013, the Company transitioned to a third-party product transportation network and moved away from the Company's existing private fleet. The cost related to this transition was $12.2 million, consisting of early lease termination on transportation equipment of $9.8 million and employee severance and other costs of $2.4 million. At December 31, 2013, the Company had an immaterial liability related to these restructuring costs. All remaining costs related to the restructuring were paid in the first quarter of 2014.
	The Company recognizes transaction related costs as expense in the period incurred. For the years ended December 31, 2013 and 2012, the Company incurred $0.2 million and $1.9 million, respectively, in transaction related costs.
	Other Items
	Management realignment. During 2014, the Company incurred $7.8 million of expenses associated with changes among the executive leadership team. These expenses related principally to $6.3 million in executive severance, $0.2 million of accelerated non-cash stock-based compensation expense net of forfeitures, and $1.3 million for the recruiting and hiring of new executive leadership.
	International franchise receivable reserve. During 2014, the Company recorded a $4.2 million reserve against receivables with its international franchisees. An allowance for international franchisees is calculated based on unpaid, non-collateralized amounts associated with their receivable balance. The collectability of receivables from certain international franchisees has become uncertain due principally to the current financial condition of those franchisees.
	Reversal of contingent purchase price. For the years ended December 31, 2014 and 2013, the Company reversed $4.4 million and $0.9 million, respectively, of contingent purchase price associated with Discount Supplements and LuckyVitamin.com ("Lucky Vitamin") based on changes in the probability that all required targets of the purchase agreement would be met ("Reversal of Contingent Purchase Price").
	Other (income) expense, net. Other (income) expense includes the gain on sale of company-owned stores to franchisees and foreign currency transaction (gain) loss. During the years ended December 31, 2014, 2013 and 2012 the Company sold 26, 9 and 10 company-owned stores to franchisees, respectively, resulting in gains of $9.9 million, $2.7 million and $0.8 million.
	Revision
	Certain amounts in the consolidated financial statements of prior year periods have been revised to conform to the current period's presentation with no impact on previously reported operating income or stockholders' equity. Specifically, the gains resulting from the sales of Company-owned stores are presented in "Other (income) expense, net" on the consolidated statements of income and the related cash proceeds are presented in "Other investing activities" as an investing cash inflow on the consolidated statements of cash flows. These gains were previously presented in “Gross profit” on the consolidated statements of income with the related cash proceeds being presented as an operating activity in the consolidated statements of cash flows. Certain other amounts in the consolidated financial statements of prior year periods have been revised to conform to the current period’s presentation. None of these revisions are material to any of the prior year periods.
	Recently Issued Accounting Pronouncements
	In June 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") ASU 2014-12, which updates guidance on performance stock awards. The update states that for any award that has a performance target that affects vesting and that could be achieved after the requisite period, that performance target should still be treated as a performance condition. This standard is effective for fiscal years beginning after December 15, 2015. The Company is currently evaluating the impact this guidance will have on the consolidated financial statements.
	In May 2014, the FASB issued ASU 2014-09, which updates revenue recognition guidance relating to contracts with customers. This standard states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This standard is effective for fiscal years beginning after December 15, 2016. The Company is currently evaluating the impact this guidance will have on the consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11 regarding the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This standard requires entities to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss ("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. This ASU requires entities to assess whether to net the unrecognized tax benefit with a deferred tax asset as of the reporting date. This guidance is effective for fiscal years beginning after December 15, 2013, with early adoption permitted. The Company adopted this guidance during the first quarter of 2014, and it did not have a material impact on the consolidated financial statements.

	At December 31, 2014 and 2013, the Company had deferred tax assets relating to foreign and state NOLs in the amount of $8.4 million with lives ranging from 5 to 20 years. As of December 31, 2014 and 2013, a valuation allowance was provided for certain NOLs, as the Company currently believes that these NOLs may not be realizable prior to their expiration. During 2014, 2013 and 2012, the Company recorded a valuation allowance adjustment of $1.6 million, $1.4 million and $1.2 million, respectively, which reduced income tax expense. The valuation allowance was adjusted based on a change in circumstances, including anticipated future earnings and a tax law change, which caused a change in judgment about the realizability of certain deferred tax assets related to NOLs.
	The Company does not have any material undistributed earnings of international subsidiaries at December 31, 2014 and 2013 as these subsidiaries are either considered to be branches for United States tax purposes, to have incurred cumulative NOLs, or to have only minimal undistributed earnings.
	Holdings files a consolidated federal tax return and various consolidated and separate tax returns as prescribed by the tax laws of the state, local and international jurisdictions in which it and its subsidiaries operate. The statutes of limitation for the Company’s U.S. federal income tax returns are closed for years through 2010. The Company's 2010 and 2011 federal income tax returns have been examined by the Internal Revenue Service. The Internal Revenue Service closed the examination without making any material adjustments to the returns. The Company has various state and local jurisdiction tax years open to possible examination (earliest open period 2010), and the Company also has certain state and local tax filings currently under audit. As of December 31, 2014, the Company believes that it is appropriately reserved for any potential federal and state income tax exposures.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
		December 31,
		2014				2013				2012
	(in thousands)
Balance of unrecognized tax benefits at beginning of period	$	10,848			$	12,882			$	10,574
Additions for tax positions taken during current period	1,524				873				1,215
Additions for tax positions taken during prior periods	116				1,965				4,220
Reductions for tax positions taken during prior periods	(527		)		(4,068		)		(1,439		)
Settlements	(309		)		(804		)		(1,688		)
Balance of unrecognized tax benefits at end of period	$	11,652			$	10,848			$	12,882
As of December 31, 2014, the Company is not aware of any positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within the next 12 months. Accrued interest and penalties were $4.2 million at December 31, 2014 and 2013. At December 31, 2014, the amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $11.7 million. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its unrecognized tax benefits reflect the most likely outcome. The Company adjusts these unrecognized tax benefits, as well as the related interest, in light of changing facts and circumstances. Settlement of any particular position could require the use of cash. Favorable resolution would be recognized as a reduction to the effective income tax rate in the period of resolution.

GOODWILL, BRANDS, AND OTHER INTANGIBLE ASSETS, NET	12 Months Ended
	Dec. 31, 2014
Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL, BRANDS, AND OTHER INTANGIBLE ASSETS, NET	GOODWILL, BRANDS, AND OTHER INTANGIBLE ASSETS, NET
	In connection with the acquisition of the Company by Ares Corporate Opportunities Fund II L.P.  and Ontario Teachers’ Pension Plan Board in March 2007, the Company recorded approximately $600 million of goodwill and $720 million of indefinite-lived intangible assets related to its brands.  In 2011, the Company completed an initial public offering of its common stock, and in 2012, completed a series of selling stockholder offerings. As of December 31, 2014, these entities own an immaterial number of shares of the Company’s common stock.
	For the 2014 annual goodwill impairment assessment, management proceeded directly to the first step of the quantitative test for all of the Company's reporting units. The estimated fair values for all reporting units were substantially in excess of their respective carrying values, except for approximately $25 million of goodwill associated with the Discount Supplements reporting unit, which had an estimated fair value that exceeded its carrying value by less than 10%. As a result of the Company's annual test, no goodwill impairment was recorded. While the Discount Supplements reporting unit passed the first step of the impairment test, if its operating profits deteriorate in the future, the estimated fair value could decline and lead to a potential goodwill impairment in the future.
	For the years ended December 31, 2014, 2013 and 2012, the Company acquired 27, 16 and 29 franchise stores, respectively. These acquisitions are accounted for utilizing the acquisition method of accounting, and the Company allocated the purchase price by recognizing acquired inventory, fixed assets, franchise rights and other net assets at fair value with any excess being recognized as goodwill, with a related reduction to receivables and cash. For the years ended December 31, 2014, 2013 and 2012, the total purchase prices associated with these acquisitions were $3.7 million, $2.9 million and $4.4 million, respectively, of which $2.0 million, $1.7 million and $2.1 million was paid in cash.
	On April 17, 2014, the Company acquired the assets and assumed the liabilities of The Health Store, which was accounted for as a business combination. The total purchase price for this acquisition was approximately $8.9 million, of which $6.9 million,$0.8 million, and $1.2 million was allocated to goodwill, definite-lived intangible assets and other net assets, respectively. On October 2, 2013, the Company acquired the assets and assumed the liabilities of Discount Supplements, which was accounted for as a business combination. The total purchase price for this acquisition was approximately $33.3 million, of which $24.6 million, $9.6 million, $0.9 million was allocated to goodwill, definite-lived intangible assets and other net liabilities, respectively.
	The Company's acquisitions of Discount Supplements, The Health Store and franchise stores did not have a material impact on the Company's consolidated financial statements, and therefore, pro forma disclosures have not been presented.

	The following is a summary of the Company's debt:
	Senior Credit Facility.    In March 2011, General Nutrition Centers, Inc. ("Centers"), a wholly owned subsidiary of Holdings, entered into the Senior Credit Facility, consisting of the Term Loan Facility and the Revolving Credit Facility. As of December 31, 2014, the Company believes that it is in compliance with all covenants under the Senior Credit Facility. As of December 31, 2014, $1.1 million of letters of credit were pledged under the $130 million Revolving Credit Facility. The Senior Credit Facility permits the Company to prepay a portion or all of the outstanding balance without incurring penalties (except London Interbank Offering Rate ("LIBOR") breakage costs). GNC Corporation, the Company's indirect wholly owned subsidiary ("GNC Corporation"), and Centers' existing and future domestic subsidiaries have guaranteed Centers' obligations under the Senior Credit Facility. In addition, the Senior Credit Facility is collateralized by first priority pledges (subject to permitted liens) of substantially all of Centers' assets, including its equity interests and the equity interests of its domestic subsidiaries.
	On August 1, 2012, Centers amended the Senior Credit Facility to, among other amendments, provide additional commitments of $200 million for incremental term loans. In October 2012, Centers entered into an amendment to the Senior Credit Facility that included changes to ABR, LIBOR, and Applicable Margin rates. Specifically, as amended, the facility allowed the Company to borrow at a rate per annum equal to (A) the sum of (i) the greater of (a) the prime rate (as publicly announced by JPMorgan Chase Bank, N.A. as its prime rate in effect), (b) the federal funds effective rate plus 0.50%, (c) one month adjusted LIBOR plus 1.0% and (d) 2.25% with respect to the Revolving Credit Facility and 2.00% with respect to the Term Loan Facility plus (ii) the applicable margin of 2.0% with respect to the Revolving Credit Facility and 1.75% with respect to the Term Loan Facility or (B) the sum of (i) the greater of (a) adjusted LIBOR or (b) 1.25% with respect to Revolving Credit Facility and 1.00% with respect to Term Loan Facility plus (ii) an applicable margin of 3.0% for amounts borrowed under the Revolver Credit Facility and 2.75% with respect to amounts outstanding under the Term Loan Facility. As of December 31, 2012, the Company's interest rate on its Senior Credit Facility was 3.75%, as a result of the interest rate minimum requirement as described above.
	During the fourth quarter of 2013, Centers amended and restated the Senior Credit Facility to, among other amendments, increase the size of the Term Loan Facility by $252.5 million, increase the amount available for borrowings under the Revolving Credit Facility from $80 million to $130 million, extend the Revolving Credit Facility maturity date to March 2017, and extend the maturity of the Term Loan Facility to March 2019. The amendment also included changes to ABR, LIBOR, and Applicable Margin rates. Specifically, the Company may, at its option, borrow at a rate per annum equal to (A) the sum of (i) the greater of (a) the prime rate (as publicly announced by JPMorgan Chase Bank, N.A. as its prime rate in effect), (b) the federal funds effective rate plus 0.50%, (c) one month adjusted LIBOR plus 1.0% or (d) 1.75% plus (ii) the margin of 1.25% with respect to borrowings under the Revolving Credit Facility and 1.5% with respect to amounts outstanding under the Term Loan Facility or (B) the sum of (i) the greater of (a) adjusted LIBOR or (b) 0.75% plus (ii) the applicable margin of 2.25% with respect to borrowings under the Revolving Credit Facility and 2.5% with respect to amounts outstanding under the Term Loan Facility. As of December 31, 2014 and 2013, the Company's interest rate on its Senior Credit Facility was 3.25%, as a result of the interest rate minimum requirement as described above. As of December 31, 2014 and 2013, the outstanding letter of credit fee was 2.50%, and the commitment fee on the undrawn portion of the Revolving Credit Facility was 0.5%.
	The Senior Credit Facility contains customary covenants, including incurrence covenants and certain other limitations on the ability of GNC Corporation, Centers, and Centers' subsidiaries to, among other things, make optional payments in respect of other debt instruments, pay dividends or other payments on capital stock, and enter into arrangements that restrict their ability to pay dividends or grant liens.

Financial Instruments, Owned, at Fair Value [Abstract]
FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS	FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS
	Fair value is defined as a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the standard establishes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:
	Level 1 — observable inputs such as quoted prices in active markets for identical assets and liabilities;
	Level 2 — observable inputs such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, other inputs that are observable, or can be corroborated by observable market data; and
	Level 3 — unobservable inputs for which there are little or no market data, which require the reporting entity to develop its own assumptions.
	The following table presents the Company's financial assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2014 by level within the fair value hierarchy:
		Fair Value Measurements Using
		Level 1		Level 2		Level 3
		(in thousands)
	Cash equivalents	$	43,365	$	—	$	—
	Other long-term assets	$	—	$	7,814	$	—
	The following table presents the Company's financial assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2013 by level within the fair value hierarchy:

		(in thousands)
	Cash equivalents	$	142,800	$	—	$	—
	Other long-term assets	$	—	$	6,124	$	—
	Other long-term assets classified as Level 2 consist of assets related to the Company's non-qualified deferred compensation plan. The assets related to this plan are adjusted based on changes in the fair value of the underlying investments. Since the fair value of the investments is based on quoted prices of similar items in active markets, the assets are classified within Level 2 on the fair value hierarchy.
	The actual and estimated fair values of the Company's financial instruments were as follows:
		December 31, 2014				December 31, 2013
		Carrying		Fair		Carrying		Fair
		Amount		Value		Amount		Value
		(in thousands)
	Cash and cash equivalents	$	133,834	$	133,834	$	226,217	$	226,217

	Long-term debt (including current portion)	1,342,378		1,288,683		1,347,099		1,343,732
	The carrying amounts of cash and cash equivalents, receivables, accounts payable and accrued liabilities approximate their respective fair values because of the short maturities of these instruments. Based on the interest rates currently available and their underlying risk, the carrying value of the franchise notes receivable approximates its fair value. As considerable judgment is required to determine these estimates, changes in the assumptions or methodologies may have an effect on these estimates. The Company determined the estimated fair value of its debt by using Level 2 inputs, which consist of the instrument's trading value in markets that are not active.

Leases, Operating [Abstract]
LONG-TERM LEASE OBLIGATIONS	LONG-TERM LEASE OBLIGATIONS
	The Company enters into operating leases covering its retail store locations. The Company is the primary lessor of the majority of all leased retail store locations and sublets applicable locations to individual franchisees. The leases generally provide for an initial term of between five and ten years, and may include renewal options for varying terms thereafter. The leases require minimum monthly rental payments and a pro rata share of landlord allocated common operating expenses. The majority of retail leases also require additional rentals based on a percentage of sales in excess of specified levels. According to the individual lease specifications, real estate taxes, insurance and other related costs may be included in the rental payment or charged in addition to rent. Other lease expenses relate to and include distribution facilities, transportation equipment, data processing equipment and automobiles.
	As the Company is the primary lessee for the majority of the franchise store locations, it is ultimately liable for the lease payments to the landlord. The Company makes the payments to the landlord directly, and then bills the franchisee for reimbursement of this cost. If a franchisee defaults on its sub-lease and its sub-lease is terminated, the Company has in the past converted, and expects in the future to, convert any such franchise store into a company-owned store and fulfill the remaining lease obligation.
	The composition of the Company's rental expense included the following components:
		Year ended December 31,

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES
	Litigation
	The Company is engaged in various legal actions, claims and proceedings arising in the normal course of business, including claims related to breach of contracts, products liabilities, intellectual property matters and employment-related matters resulting from the Company's business activities.
	The Company records accruals for outstanding legal matters when it believes it is probable that a loss will be incurred and the amount of such loss can be reasonably estimated. The Company evaluates, on a quarterly basis, developments in legal matters that could affect the amount of any accrual and developments that would make a loss contingency both probable and reasonably estimable. If a loss contingency is not both probable and estimable, the Company does not establish an accrued liability. Currently, none of the Company's accruals for outstanding legal matters are material individually or in the aggregate to the Company's financial position. However, if the Company ultimately is required to make a payment in connection with an adverse outcome in any of the matters discussed below, it is possible that it could have a material adverse effect on the Company's business, financial condition, results of operations or cash flows.
	The Company's contingencies are subject to substantial uncertainties, including for each such contingency the following, among other factors: (i) the procedural status of the case; (ii) whether the case has or may be certified as a class action suit; (iii) the outcome of preliminary motions; (iv) the impact of discovery; (v) whether there are significant factual issues to be determined or resolved; (vi) whether the proceedings involve a large number of parties and/or parties and claims in multiple jurisdictions or jurisdictions in which the relevant laws are complex or unclear; (vii) the extent of potential damages, which are often unspecified or indeterminate; and (viii) the status of settlement discussions, if any, and the settlement posture of the parties. Consequently, except as otherwise noted below with regard to a particular matter, the Company cannot predict with any reasonable certainty the timing or outcome of the legal matters described below, and the Company is unable to estimate a possible loss or range of loss.
	As a manufacturer and retailer of nutritional supplements and other consumer products that are ingested by consumers or applied to their bodies, the Company has been and is currently subjected to various product liability claims. Although the effects of these claims to date have not been material to the Company, it is possible that current and future product liability claims could have a material adverse effect on its business or financial condition, results of operations or cash flows. The Company currently maintains product liability insurance with a deductible/retention of $4.0 million per claim with an aggregate cap on retained loss of $10.0 million. The Company typically seeks and has obtained contractual indemnification from most parties that supply raw materials for its products or that manufacture or market products it sells. The Company also typically seeks to be added, and has been added, as an additional insured under most of such parties' insurance policies. The Company is also entitled to indemnification by Numico for certain losses arising from claims related to products containing ephedra or Kava Kava sold prior to December 5, 2003. However, any such indemnification or insurance is limited by its terms and any such indemnification, as a practical matter, is limited to the creditworthiness of the indemnifying party and its insurer, and the absence of significant defenses by the insurers. Consequently, the Company may incur material products liability claims, which could increase its costs and adversely affect its reputation, revenue and operating income.
	Hydroxycut Claims.    On May 1, 2009, the FDA issued a warning on several Hydroxycut-branded products manufactured by Iovate Health Sciences U.S.A., Inc. ("Iovate") based on 23 reports of liver injuries from consumers who claimed to have used the products between 2002 and 2009. As a result, Iovate voluntarily recalled 14 Hydroxycut-branded products.
	Following the recall, the Company was named, among other defendants, in approximately 93 lawsuits related to Hydroxycut-branded products in 14 states. The United States Judicial Panel on Multidistrict Litigation consolidated pretrial proceedings of many of the pending actions in the Southern District of California (In re: Hydroxycut Marketing and Sales Practices Litigation, MDL No. 2087), and Iovate previously accepted the Company’s tender request for defense and indemnification under its purchasing agreement with the Company in these matters.
	As of December 31, 2014, there were 73 pending lawsuits related to Hydroxycut in which the Company had been named: 67 individual, largely personal injury claims and six putative class action cases, generally inclusive of claims of consumer fraud, misrepresentation, strict liability and breach of warranty. In May 2013, the parties to the individual personal injury cases signed a Master Settlement Agreement, under which the Company is not required to make any payments. Settlement payments are being made exclusively by Iovate and dismissals are expected to be entered in these actions in the near term. The parties in the consolidated class actions reached a settlement, which was approved by the Court on October 20, 2014 and which does not require the Company to make any payments. Following final resolution of the individual personal injury cases and the settlement of the consolidated class action suits, all of the Hydroxycut claims currently pending against the Company will be resolved without any payment by the Company.
	DMAA/Aegeline Claims.    Prior to December 2013, the Company sold products manufactured by third parties that contained derivatives from geranium known as 1.3-dimethylpentylamine/ dimethylamylamine/13-dimethylamylamine, or "DMAA," which were recalled from the Company's stores in November 2013, and/or Aegeline, a compound extracted from bael trees. As of December 31, 2014, the Company was named in 21 lawsuits involving products containing DMAA, including 18 personal injury cases and three putative class action cases.
	As a general matter, the proceedings associated with the personal injury cases, which generally seek indeterminate money damages, are in the early stages, and any losses that may arise from these matters are not probable or reasonably estimable at this time. The Company is contractually entitled to indemnification by its third-party vendors with regard to these matters, although the Company’s ability to obtain full recovery in respect of any such claims against it is dependent upon the creditworthiness of the vendors and/or their insurance coverage and the absence of any significant defenses available to its insurer.
	The Company previously was named in a third putative class action case in the United States District Court for the Disctrict of New Jersey, which was dismissed with prejudice in December 2014. The two remaining class action claims were consolidated and, in October 2014, the United States District Court for the Northern District of Florida preliminarily a settlement agreement among the parties. A final hearing with regard to the proposed settlement, which does not require any payment by the Company, currently is scheduled for February 26, 2015.
	California Wage and Break Claim.    On November 4, 2008, 98 plaintiffs filed individual claims against the Company in the Superior Court of the State of California for the County of Orange, which was removed to the U.S. District Court, Central District of California on February 17, 2009. Each of the plaintiffs had previously been a member of a purported class in a lawsuit filed against the Company in 2007 and resolved in September 2009. The plaintiffs allege that they were not provided all of the rest and meal periods to which they were entitled under California law, and further allege that the Company failed to pay them split shift and overtime compensation to which they were entitled under California law. The plaintiffs also allege derivative claims for inaccurate wage statements, failure to pay wages due at termination, and penalty claims under the California Labor Code. In June 2013, a trial was conducted with respect to the claims of seven of the plaintiffs. The jury returned a verdict in favor of the Company on all claims submitted to the jury, and the Court entered an order in favor of the Company on the one claim submitted to the Court. The claims of five other plaintiffs have been resolved and the claims of eighty-six plaintiffs remain, with respect to which discovery is ongoing. As any losses that may arise from these matters are not probable or reasonably estimable at this time, no liability has been accrued in the accompanying financial statements.
	On July 21, 2011, Charles Brewer, on behalf of himself and all others similarly situated, sued General Nutrition Corporation in federal court, alleging state and federal wage and hour claims (U.S. District Court, Northern District of California, Case No. 11CV3587). On October 7, 2011, plaintiff filed an eight-count amended complaint alleging, inter alia, meal, rest break and overtime violations. On October 21, 2011, the Company filed a motion to dismiss the complaint and on December 14, 2011 the court dismissed count six (the federal overtime claim) giving plaintiffs an opportunity to amend the complaint within thirty days. On January 13, 2012, plaintiff filed a Second Amended complaint. On September 18, 2012, Plaintiff filed a Motion for Conditional Certification and on January 7, 2013, the Court conditionally certified a Fair Labor Standards Act class with respect to one of Plaintiff's claims. As any losses that may arise from these matters are not probable or reasonably estimable at this time, no liability has been accrued in the accompanying financial statements.
	On February 29, 2012, former Senior Store Manager, Elizabeth Naranjo, individually and on behalf of all others similarly situated sued General Nutrition Corporation in the Superior Court of the State of California for the County of Alameda (Case No. RG 12619626). The complaint contains eight causes of action, alleging, inter alia, meal, rest break, and overtime violations. As any losses that may arise from these matters are not probable or reasonably estimable at this time, no liability has been accrued in the accompanying financial statements.
	FLSA Matters. On June 29, 2010, Dominic Vargas and Anne Hickok, on behalf of themselves and all others similarly situated, sued General Nutrition Corporation and the Company in federal court (U.S. District Court, Western District of Pennsylvania, Case No. 2:05-mc-02025). The two-count complaint alleged, generally, that plaintiffs were required to perform work on an uncompensated basis and that the Company failed to pay overtime for such work. The parties to the case reached a tentative settlement on December 3, 2014. The settlement remains subject to Court approval.
	Jason Olive v. General Nutrition Corp. In April 2012, Jason Olive filed a complaint in the Superior Court of California, County of Los Angeles (Case No. BC482686), for misappropriation of likeness in which he alleges that the Company continued to use his image in stores after the expiration of the license to do so in violation of common law and California statutes. Mr. Olive is seeking compensatory, punitive and statutory damages and attorneys’ fees and costs. The trial in this matter previously scheduled for December 2014 was postponed and no new trial date has been set. As of December 31, 2014, an immaterial liability has been accrued in the accompanying financial statements.
	Commitments
	In addition to operating leases obtained in the normal course of business, the Company maintains certain purchase commitments with various vendors to ensure its operational needs are fulfilled. As of December 31, 2014, such future purchase commitments consisted of $2.4 million. Other commitments related to the Company's business operations cover varying periods of time and are not significant. All of these commitments are expected to be fulfilled with no adverse consequences to the Company's operations or financial condition.
	Environmental Compliance
	In March 2008, the South Carolina Department of Health and Environmental Control (the "DHEC") requested that the Company investigate contamination associated with historical activities at its South Carolina facility. These investigations have identified chlorinated solvent impacts in soils and groundwater that extend offsite from the facility. The Company entered into a Voluntary Cleanup Contract with the DHEC regarding the matter on September 24, 2012. Pursuant to such contract, the Company will submit a plan for additional investigations to the DHEC and will implement the plan upon DHEC's approval. After the Company completes the investigations to understand the extent of the chlorinated solvent impacts, the Company will develop appropriate remedial measures for DHEC approval. At this stage of the investigation, however, it is not possible to estimate the timing and extent of any remedial action that may be required, the ultimate cost of remediation, or the amount of the Company's potential liability, therefore no liability is recorded.
	In addition to the foregoing, the Company is subject to numerous federal, state, local and foreign environmental and health and safety laws and regulations governing its operations, including the handling, transportation and disposal of the Company's non-hazardous and hazardous substances and wastes, as well as emissions and discharges from its operations into the environment, including discharges to air, surface water and groundwater. Failure to comply with such laws and regulations could result in costs for remedial actions, penalties or the imposition of other liabilities. New laws, changes in existing laws or the interpretation thereof, or the development of new facts or changes in their processes could also cause the Company to incur additional capital and operating expenditures to maintain compliance with environmental laws and regulations and environmental permits. The Company is also subject to laws and regulations that impose liability and cleanup responsibility for releases of hazardous substances into the environment without regard to fault or knowledge about the condition or action causing the liability. Under certain of these laws and regulations, such liabilities can be imposed for cleanup of previously owned or operated properties, or for properties to which substances or wastes that were sent in connection with current or former operations at its facilities. The presence of contamination from such substances or wastes could also adversely affect the Company's ability to sell or lease its properties, or to use them as collateral for financing. From time to time, the Company has incurred costs and obligations for correcting environmental and health and safety noncompliance matters and for remediation at or relating to certain of the Company's properties or properties at which the Company's waste has been disposed. However, compliance with the provisions of national, state and local environmental laws and regulations has not had a material effect upon the Company's capital expenditures, earnings, financial position, liquidity or competitive position. The Company believes it has complied with, and is currently complying with, its environmental obligations pursuant to environmental and health and safety laws and regulations and that any liabilities for noncompliance will not have a material adverse effect on its business, financial performance or cash flows. However, it is difficult to predict future liabilities and obligations, which could be material.

EARNINGS PER SHARE	The following table represents the Company's basic and dilutive weighted average shares:
		Year ended December 31,
		2014	2013	2012
		(in thousands)
	Basic weighted average shares	90,493	96,481	103,503
	Effect of dilutive employee stock-based compensation awards	425	902	1,408
	Diluted weighted averages shares	90,918	97,383	104,911
	For the years ended December 31, 2014, 2013 and 2012, the Company had immaterial amounts of shares from unexercised stock options that were not included in the computation of diluted earnings per share because the impact of applying the treasury stock method to these options was anti-dilutive.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION PLANS	STOCK-BASED COMPENSATION PLANS
	The Company has outstanding stock-based compensation awards that were granted by the compensation committee of Holdings' Board of Directors (the "Compensation Committee") under the following two stock-based employee compensation plans:
	•	the GNC Holdings, Inc. 2011 Stock and Incentive Plan (the "2011 Stock Plan") adopted in March 2011; and
	•	the GNC Acquisition Holdings Inc. 2007 Stock Incentive Plan adopted in March 2007 (as amended, the "2007 Stock Plan").
	Both plans have provisions that allow for the granting of stock options, restricted stock and other stock based awards and are available to certain eligible employees, directors, consultants or advisors as determined by the Compensation Committee. Stock options under the plans were granted with exercise prices at or above fair market value on the date of grant, typically vest over a four- or five-year period and expire seven or ten years from the date of grant. No stock appreciation rights, restricted stock, deferred stock or performance shares were granted under the 2007 Stock Plan. The Company will not grant any additional awards under the 2007 Stock Plan.
	Up to 8.5 million shares of common stock may be issued under the 2011 Stock Plan (subject to adjustment to reflect certain transactions and events specified in the 2011 Stock Plan for any award grant), of which 5.9 million shares remain available for issuance as of December 31, 2014. If any award granted under the 2011 Stock Plan expires, terminates or is cancelled without having been exercised in full, the number of shares underlying such unexercised award will again become available for awards under the 2011 Stock Plan. The total number of shares of common stock available for awards under the 2011 Stock Plan will be reduced by (i) the total number of stock options or stock appreciation rights exercised, regardless of whether any of the shares of common stock underlying such awards are not actually issued to the participant as the result of a net settlement, and (ii) any shares of common stock used to pay any exercise price or tax withholding obligation. In addition, the number of shares of common stock that are subject to restricted stock, performance shares or other stock-based awards that are not subject to the appreciation of the value of a share of common stock ("Full Share Awards") that may be granted under the 2011 Stock Plan is limited by counting shares granted pursuant to such awards against the aggregate share reserve as 1.8 shares for every share granted. If any stock option, stock appreciation right or other stock-based award that is not a Full Share Award is cancelled, expires or terminates unexercised for any reason, the shares covered by such awards will again be available for the grant of awards under the 2011 Stock Plan. If any shares of common stock that are subject to restricted stock, performance shares or other stock-based awards that are Full Share Awards are forfeited for any reason, 1.8 shares of common stock will again be available for the grant of awards under the 2011 Stock Plan.
	The Company utilizes the Black Scholes model to calculate the fair value of options under both the 2011 Stock Plan and the 2007 Stock Plan. The resulting compensation cost is recognized in the Company's financial statements over the option vesting period. The Company recognized $5.9 million, $7.8 million and $4.8 million of non-cash compensation expense relating to all stock-based awards for the years ended December 31, 2014, 2013 and 2012, respectively. At December 31, 2014, there was approximately $6.5 million of total unrecognized compensation cost related to non-vested stock-based compensation for all awards previously made that are expected to be recognized over a weighted average period of approximately 1.6 years.
	During the year ended December 31, 2014, the total intrinsic value of options exercised was $13.9 million and the total amount of cash received from the exercise of options was $22.2 million. The total tax impact associated with all awards for the year ended December 31, 2014 resulted in an excess tax benefit of $3.7 million, which was recorded to paid-in-capital.
	During the year ended December 31, 2013, the total intrinsic value of options exercised was $44.6 million and the total amount of cash received from the exercise of options was $14.6 million. The total tax impact associated with all awards for the year ended December 31, 2013 resulted in an excess tax benefit of $15.4 million, which was recorded to paid-in-capital.
	During the year ended December 31, 2012, the total intrinsic value of options exercised was $101.8 million and the total amount of cash received from the exercise of options was $26.0 million. The total tax impact associated with all awards for the year ended December 31, 2012 resulted in an excess benefit of $37.5 million, which was recorded to paid-in-capital.
	The following table sets forth a summary of stock options under all plans for the year ended December 31, 2014:
		Total Options			Weighted		Weighted Average		Aggregate
					Average		Remaining		Intrinsic Value
					Exercise Price		Contractual Term		(in thousands)
							(in years)
	Outstanding at December 31, 2013	1,887,154			$	24.14
	Granted	202,606			$	34.2
	Exercised	(970,444	)		$	22.78
	Forfeited	(372,783	)		$	29.03
	Outstanding at December 31, 2014	746,533			$	26.19	5.9		$	15,505
	Exercisable at December 31, 2014	286,136			$	21.24	4.5		$	7,359
	The weighted average fair value of options granted during 2014, 2013 and 2012 was $11.08, $16.16, and $10.38, respectively.
	The Black-Scholes model utilizes the following assumptions in determining a fair value: price of underlying stock, award exercise price, expected term, risk-free interest rate, expected dividend yield and expected stock price volatility over the award's expected term. Due to the utilization of these assumptions, the existing models do not necessarily represent the definitive fair value of awards for future periods. As the IPO occurred during the second quarter of 2011, the option term has been estimated by considering both the vesting period, which typically for both plans has been five or four years, and the contractual term, which historically has been either seven or ten years. Prior to the IPO, the fair value of the common stock was estimated based upon the net enterprise value of the Company, discounted to reflect the lack of liquidity and control associated with the stock. Since the consummation of the IPO, the fair value of the stock has been based upon the closing price of the common stock as reported on the NYSE. Volatility is estimated based upon the Company utilizing its current peer group average.
	The assumptions used in the Company's Black Scholes valuation related to stock option grants made during each period below were as follows:
		Year ended December 31,
		2014		2013		2012
	Dividend yield	1.5% - 1.9%		1.0% - 1.4%		1.2%-1.4%
	Expected option life	6.3 years		4.8 years		4.8-5.0 years
	Volatility factor percentage of market price	37.6% - 37.9%		35.9% - 40.5%		40.0%-40.7%
	Discount rate	1.7% - 1.9%		0.7% - 1.4%		0.6% - 0.9%
	The following table sets forth a summary of restricted stock awards granted under the 2011 Stock Plan and related information for the year ended December 31, 2014:
		Restricted			Weighted
		Stock			Average Grant-
					Date Fair Value
	Outstanding at December 31, 2013	114,981			$	25.16
	Granted	10,404			$	36.52
	Vested	(34,342	)		$	30.5
	Forfeited	(58,889	)		$	23.58
	Outstanding at December 31, 2014	32,154			$	26.03
	Under the 2011 Stock Plan, the Company granted time vesting and performance vesting restricted stock units. Time vesting restricted stock units vest over a period of three years. Performance vesting restricted stock units vest based on the passage of time, earnings per share, and revenue growth; based on the extent to which the targets are achieved, vested shares may range from 0% to 200% of the original share amount. The unrecognized compensation cost related to the performance vesting restricted stock units is adjusted as necessary to reflect changes in the probability that the vesting criteria will be achieved.
	The following table sets forth a summary of restricted stock units and performance stock units granted under the 2011 Stock Plan and related information for the year ended December 31, 2014:

RETIREMENT PLANS	RETIREMENT PLANS
	The Company sponsors a 401(k) defined contribution savings plan covering substantially all employees. Full time employees who have completed 30 days of service and part time employees who have completed 1000 hours of service are eligible to participate in the plan. The plan provides for employee contributions of 1% to 80% of individual compensation into deferred savings, subject to IRS limitations. The plan provides for Company contributions upon the employee meeting the eligibility requirements. The Company match consists of both a fixed and a discretionary match which is based on a specified financial target for all participants in the plan. The fixed match is 50% on the first 3% of the salary that an employee defers and the discretionary match could be up to an additional 50% match on the 3% deferral. A discretionary match can be approved at any time by the Company.
	An employee becomes vested in the Company match portion as follows:
	Years of Service	Percent
		Vested
	0-1	0	%
	2-Jan	33	%
	3-Feb	66	%
	3+	100	%
	The Company made cash contributions to the 401(k) plan of $1.5 million, $1.6 million and $1.5 million for the years ended December 31, 2014, 2013 and 2012, respectively. In addition, the Company made a discretionary match for the 2012 plan year of $1.5 million in February 2013, and for the 2013 plan year $0.8 million in February 2014.
	The Company has a Non-qualified Executive Retirement Arrangement Plan that covers key employees. Under the provisions of this plan, certain eligible key employees are granted cash compensation, which in the aggregate was not significant for any year presented.
	The Company has a Non-qualified Deferred Compensation Plan that provides benefits payable to certain qualified key employees upon their retirement or their designated beneficiaries upon death. This plan allows participants the opportunity to defer pretax amounts ranging from 2% to 100% of their base compensation plus bonuses. During 2014, the Company elected to match a percentage of the contributions from employees. For the year ended December 31, 2014 this contribution was $0.3 million. The Company has elected to finance any potential plan benefit obligations using corporate owned life insurance policies. All assets relating to the non-qualified deferred compensation plan are held in a rabbi trust.

Segment Reporting [Abstract]
SEGMENTS	SEGMENTS
	The Company aggregates its operating segments into three reportable segments, which include Retail, Franchising, and Manufacturing/Wholesale. The Retail reportable segment includes the Company's corporate store operations in the United States, Canada, Puerto Rico, Ireland and its websites GNC.com, Lucky Vitamin, and Discount Supplements. The Franchise reportable segment represents the Company's franchise operations, both domestically and internationally. The Manufacturing/Wholesale reportable segment represents the Company's manufacturing operations in South Carolina and the Wholesale business. This segment supplies the Retail and Franchise segments, along with various third parties, with finished products for sale. The accounting policies of the segments are the same as those described in Note 2, "Basis of Presentation and Summary of Significant Accounting Policies." The Company's chief operating decision maker evaluates segment operating results based primarily on performance indicators, including sales and operating income or loss. Operating income or loss of each reportable segment excludes certain items that are managed at the consolidated level, such as warehousing, distribution and other corporate costs. The following table represents key financial information for each of the Company's reportable segments.

Franchise Revenue
As of December 31, 2014, the Company had over 3,200 franchise locations domestically and internationally. The Company's Franchise segment generates revenues primarily through product sales to franchisees, royalties and franchise fees. The Company enters into franchise agreements with initial terms of ten years. The Company charges franchisees three types of flat franchise fees associated with stores: initial, transfer and renewal. The initial franchise fee is payable prior to the franchise store opening as consideration for the initial franchise rights and services performed by the Company. Transfer fees are paid as consideration for the same rights and services as the initial fee and occur when a former franchisee transfers ownership of the franchise location to a new franchisee. This is typically a reduced fee compared to the initial franchise fee. The renewal franchise fee is charged to existing franchisees upon renewal of the franchise contract. This fee is similar to, but typically less than, the initial fee.
Once the franchise store is opened, transferred or renewed, the Company has no further obligations under these fees to the franchisee. Therefore, all initial, transfer and renewal franchise fee revenue is recognized in the period in which a franchise store is opened, transferred or date the contract period is renewed. The Company recognized initial franchise fees of $3.6 million, $4.9 million, and $3.7 million for the years ended December 31, 2014, 2013 and 2012, respectively.
The following is a summary of the Company's franchise revenue by type:
	Year ended December 31,
	2014			2013			2012
	(in thousands)
Product sales	$	358,247		$	363,810		$	339,922

Other	7,944			6,924			6,564
Total franchise revenue	$	432,828		$	436,917		$	406,297
In addition to the Retail and Franchise revenue discussed above, Manufacturing/Wholesale sales are generated from sales of manufactured products to third parties, primarily in the VMHS product category.

BASIS_OF_PRESENTATION_AND_SUMM1

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation.    The consolidated financial statements include the accounts of Holdings and all of its subsidiaries. All inter-company transactions have been eliminated in consolidation. The Company has no relationships with unconsolidated entities or financial partnerships, commonly referred to as variable interest entities.
Use of Estimates	Use of Estimates.    The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. Accordingly, these estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. On a regular basis, management reviews its estimates utilizing currently available information, changes in facts and circumstances, historical experience and reasonable assumptions. After such reviews and if deemed appropriate, those estimates are adjusted accordingly. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents.    The Company considers cash and cash equivalents to include all cash and liquid deposits and investments with an original maturity of three months or less. The majority of payments due from banks for third-party credit and debit cards process within 24 to 72 hours, and are classified as cash equivalents.
Receivables, net	Receivables, net.    The Company extends credit terms for sales of product to its franchisees and, to a lesser extent, various third-party customers. Receivables consist principally of trade receivables of $133.4 million and $140.8 million at December 31, 2014 and 2013, respectively, and include unpaid invoices for product sales, franchisee royalties and lease payments. The Company monitors the financial condition of the Company's franchisees and other third-party customers and establishes an allowance for doubtful accounts for balances estimated to be uncollectible. In addition to considering the aging of receivable balances and assessing the financial condition of the Company's franchisees, the Company considers each domestic franchisees' inventory and fixed assets, which the Company can use as collateral in the event of a default by the franchisee. An allowance for international franchisees is calculated based on unpaid, non-collateralized amounts associated with their receivable balance. The allowance for doubtful accounts was $6.2 million and $1.9 million at December 31, 2014 and 2013, respectively.
Inventories	Inventories.    Inventory components consist of raw materials, work-in-process, finished product and packaging supplies. Inventories are stated at the lower of cost or market on a first in/first out basis ("FIFO"). The Company regularly reviews its inventory levels in order to identify slow moving and short dated products, expected length of time for product to be sold and future expiring product and adjusts the carrying value for such inventory to estimated net realizable value.
Property, Plant and Equipment	Property, Plant and Equipment.    Property, plant and equipment expenditures are recorded at cost. Depreciation and amortization are recognized using the straight-line method over the estimated useful life of the property. The estimated useful lives range from one to fifteen years across all asset classes with the exception of buildings, which are depreciated over thirty years and building improvements, which are depreciated over their estimated useful life or the remaining useful life of the related building, whichever period is shorter. Furniture and fixtures are depreciated over three to fifteen years, and machinery and equipment is generally depreciated over ten years. Computer equipment and software costs are generally depreciated over three to five years. Improvements to retail leased premises are depreciated over the estimated useful life of the improvements or the related leases including renewals that are reasonably assured, whichever period is shorter.
	Expenditures that materially increase the value or clearly extend the useful life of property, plant and equipment are capitalized in accordance with the policies outlined above. Repair and maintenance costs incurred in the normal operations of business are expensed as incurred. Gains/losses from the sale of property, plant and equipment are recognized in current operations.
Goodwill and Intangible Assets	Goodwill and Intangible Assets.    Goodwill represents the excess of purchase price over the fair value of identifiable net assets of businesses, including franchisees, acquired by the Company. Goodwill and intangible assets with indefinite useful lives are not amortized, but instead are tested for impairment at least annually or more frequently if events or changes in circumstances indicate that the assets might be impaired. The Company completes its annual impairment test in the fourth quarter.
	Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. The Company performs a qualitative assessment to determine whether it is "more likely than not" that the fair value of the reporting unit is less than its carrying value. The qualitative factors considered are general macroeconomic conditions, industry specific conditions, historical performance, and future outlooks. If it is concluded that it is "more likely than not" that the fair value of a reporting unit is less than its carrying value, the Company is required to perform a quantitative goodwill impairment test.
	The impairment test for intangible assets with indefinite useful lives consists of a comparison of the fair values of the intangible assets to their carrying values. If the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Similar to goodwill, the Company first performs a qualitative assessment to determine whether it is necessary to perform the quantitative impairment test.
	There have been no goodwill or indefinite-lived intangible asset impairments recorded to date. See Note 5, "Goodwill, Brands, and Other Intangible Assets, Net."
Long-lived Assets	Long-lived Assets.    The Company reviews the carrying value of property and equipment and amortizable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. Factors the Company considers important that may trigger an impairment review include significant changes in the manner of its use of assets, significant negative industry or economic trends, underperforming stores and store closings. These reviews may include an analysis of the current operations and capacity utilization, in conjunction with an analysis of the markets in which the businesses are operating. When an impairment review is considered necessary, a comparison is performed of the undiscounted projected cash flows from the use and eventual disposition of the asset group to the net book value of the related asset group. If it is determined that the carrying value of the asset group may not be recoverable, a charge to adjust the carrying value of the long-lived assets to estimated fair value may be required.
Revenue Recognition	Revenue Recognition.    The Company operates predominantly as a retailer, through company-owned stores, franchise stores and its e-commerce businesses and to a lesser extent through manufacturing and wholesale operations.
	The Retail segment recognizes revenue at the point of sale. Gross revenues are netted by actual customer returns and an allowance for expected customer returns. The Company records a reserve for expected customer returns based on management's estimate, which is derived from historical return data and expectations of future return volume. Revenue is deferred on sales of the Company's Gold Cards and subsequently amortized over the membership period, in order to match the discounts associated with the Gold Card program. During 2013, the Company completed the nationwide rollout of the Gold Card Member Pricing model, which evolved the Gold Card from a 20% discount the first week of the month to an everyday variable discount based on our Member Pricing model, for an annual fee.
	The Company also sells gift cards to its customers. Revenue from gift cards is recognized when the gift card is redeemed. These gift cards do not have expiration dates. Based upon historical redemption rates, a small percentage of gift cards will never be redeemed, referred to as "breakage." The Company recognizes gift card breakage revenue when the likelihood of redemption becomes remote and amounts are not escheatable.
	The Franchise segment generates revenues through product sales to franchisees, royalties and franchise fees. These revenues are netted by actual franchisee returns and an allowance for projected returns. The franchisees purchase a majority of the products they sell from the Company at wholesale prices. Revenue on product sales to franchisees is recognized when risk of loss, title and insurable risks have transferred to the franchisee. Franchise fees are paid in advance, deferred and recognized by the Company at the time of a franchise store opening. Franchise royalties are earned based on a percentage of the franchisees' sales and recognized in the period the franchisees' sales occur.
	The Manufacturing/Wholesale segment sells product to the Company's other segments and third-party customers. Revenue is recognized when risk of loss, title and insurable risks have transferred to the customer, net of estimated returns and allowances.
Cost of Sales	Cost of Sales.    The Company purchases products directly from third-party manufacturers and manufactures its own products. The Company's cost of sales includes product costs, costs of warehousing and distribution and occupancy costs.
Vendor Allowances	Vendor Allowances.    The Company receives allowances from various vendors based on either sales or purchase volumes. As the right of offset exists under these arrangements, credit earned under both arrangements are recorded as a reduction in the vendors' accounts payable balances on the balance sheet and represent the estimated amounts due to the Company under the rebate provisions of such contracts. The corresponding rebate income is recorded as a reduction to cost of sales based on inventory turnover and was $89.5 million, $92.6 million and $81.5 million for the years ended December 31, 2014, 2013 and 2012, respectively.
Research and Development	Research and Development.    Research and development costs arising from internally generated projects are expensed by the Company as incurred. The Company recognized $1.2 million, $1.4 million and $1.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. These costs are classified as "Other selling, general, and administrative" in the accompanying audited consolidated statements of income.
Advertising Expenditures	Advertising Expenditures.    The Company recognizes advertising, promotion and marketing program costs the first time the advertising takes place, with the exception of the costs of producing advertising, which are expensed as incurred during production. The Company administers national advertising funds on behalf of its franchisees. In accordance with the franchisee contracts, the Company collects advertising fees from the franchisees and utilizes the proceeds to coordinate various advertising and marketing campaigns.
Leases	Leases.    The Company has various operating leases for company-owned and franchise store locations, distribution centers, and equipment. Leases generally include amounts relating to base rental, percent rent and other charges such as common area maintenance fees and real estate taxes. Periodically, the Company receives varying amounts of reimbursements from landlords to compensate the Company for costs incurred in the construction of stores. These reimbursements are amortized by the Company as an offset to rent expense over the life of the related lease. The Company determines the period used for the straight-line rent expense for leases with option periods and conforms it to the term used for amortizing improvements.
	The Company leases an approximately 300,000 square foot-facility in Greenville, South Carolina where the majority of its proprietary products are manufactured. The Company also leases a 630,000 square foot complex located in Anderson, South Carolina, for packaging, materials receipt, lab testing, warehousing, and distribution. Both the Greenville and Anderson facilities are leased on a long-term basis pursuant to "fee-in-lieu-of-taxes" arrangements with the counties in which the facilities are located, but the Company retains the right to purchase each of the facilities at any time during the lease for $1.00, subject to a loss of tax benefits. As part of a tax incentive arrangement, the Company assigned the facilities to the counties and leases them back under operating leases. The Company leases the facilities from the counties where located, in lieu of paying local property taxes. Upon exercising its right to purchase the facilities back from the counties, the Company will be subject to the applicable taxes levied by the counties. As a result, the original cost basis of the facilities remains on the balance sheet and continues to be depreciated.
Contingencies	Contingencies.    The Company accrues a loss contingency if it is probable and can be reasonably estimated (including the satisfaction of this criteria for matters that exist as of the balance sheet date based on information which becomes available subsequent to the date of the financial statements but before the financial statements are issued). If both of the conditions above are not met, disclosure is made when there is at least a reasonable possibility that a loss contingency has been incurred. If both of the conditions above are met, disclosure is made when there is at least a reasonable possibility that an additional loss has been incurred above what is recognized as a liability in the financial statements. As facts concerning contingencies evolve and become known, management reassesses the likelihood of probable loss and makes appropriate adjustments to its financial statements.
Pre-Opening Expenditures	Pre-Opening Expenditures.    The Company recognizes the cost associated with the opening of new stores as incurred. These costs are charged to expense and are not material for the periods presented. Franchise store pre-opening costs are incurred by the franchisees.
Income Taxes	Income Taxes. The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities result from (i) the future tax impact of temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and (ii) differences between the recorded value of assets acquired in business combinations accounted for as purchases for financial reporting purposes and their corresponding tax bases. Deferred income tax assets are reduced by a valuation allowance if it is more likely than not that some portion of the deferred income tax asset will not be realized.
	The Company recognizes the tax benefit from an uncertain tax position only if it is at least more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position. The amount of the tax benefit that is recognized is measured as the largest amount of benefit that is more likely than not to be realized upon effective settlement. The Company classifies interest and penalties accrued in connection with unrecognized tax benefits as income tax expense in its consolidated statements of income.
	Refer to Note 4, "Income Taxes," for more information.
Self-Insurance	Self-Insurance.    The Company has procured insurance for: (1) general liability; (2) product liability; (3)  directors and officers liability; (4) network security and privacy liability; (5) property losses; (6) workers' compensation; and (7) various other areas. The Company is self-insured for: (1) medical benefits; (2) physical damage to the Company's vehicles for field personnel use; and (3) physical damages that may occur at the company-owned store locations. The Company is not insured for certain property and casualty risks due to the Company's assessment of frequency and severity of a loss, the cost of insurance and the overall risk analysis.
	The Company carries product liability insurance with a retention of $4.0 million per claim with an aggregate cap on retained losses of $10.0 million. The Company carries general liability insurance with retention of $250,000 per claim with an aggregate cap on retained losses of $1.0 million. The majority of the Company's workers' compensation and auto insurance policies are in deductible/retrospective plans. The Company reimburses the applicable insurance company for the workers' compensation and auto liability claims, subject to a $250,000 and $100,000 loss limit per claim, respectively.
	As part of the medical benefits program, the Company contracts with national service providers to provide benefits to its employees for all medical, dental, vision and prescription drug services. The Company then reimburses these service providers as claims are processed from Company employees. The Company maintains a specific stop loss provision of $500,000 per individual per plan year with a maximum lifetime benefit limit of $2.0 million per individual. The Company has no additional liability once a participant exceeds the $2.0 million ceiling. The Company's liability for medical claims is included as a component of accrued benefits in Note 7, "Deferred Revenue and Other Current Liabilities," and was $2.9 million and $2.0 million as of December 31, 2014 and 2013, respectively.
	The Company's self-insurance liabilities, including the estimated loss accruals for claims incurred but not paid, are determined by taking into account historical claims payment results and known trends such as claims frequency and claims severity. Management makes estimates, judgments, and assumptions with respect to the use of these calculations, including but not limited to, estimated lag time to report and pay claims, average cost per claim, network utilization rates, network discount rates, and other factors.
Stock-based Compensation	Stock-based Compensation.    The Company utilizes the Black-Scholes model to calculate the fair value of stock option awards (herein referred to as "option awards"). The grant-date fair value of the Company's restricted stock awards, time vesting restricted stock units, and performance vesting restricted stock units (collectively herein referred to as "stock awards") are based on the closing price for a share of the Company's common stock on the New York Stock Exchange (the "NYSE") on the grant date. The resulting compensation cost is recognized in the Company's financial statements over the applicable vesting period for the relevant award, net of expected forfeitures.
Earnings Per Share	Earnings Per Share.    Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding adjusted for the additional dilutive effect of unexercised option awards and unvested stock awards.
Foreign Currency	Foreign Currency.    For all foreign operations, the functional currency is the local currency. Assets and liabilities of those operations, denominated in foreign currencies, are translated into U.S. dollars using period-end exchange rates, and income and expenses are translated using the average exchange rates for the reporting period. At December 31, 2014 and 2013, foreign currency is the only component of accumulated other comprehensive income on the consolidated balance sheets. Gains or losses resulting from foreign currency transactions are included in the consolidated statements of income and were not material for the fiscal years ended December 31, 2014, 2013 and 2012.
Transaction and restructuring related costs	Transaction and restructuring related costs.    Restructuring related costs are recorded in the period in which the liability is incurred. Additionally, any change in the expected liability is recorded in the period the change in estimate occurs. In October 2013, the Company transitioned to a third-party product transportation network and moved away from the Company's existing private fleet. The cost related to this transition was $12.2 million, consisting of early lease termination on transportation equipment of $9.8 million and employee severance and other costs of $2.4 million. At December 31, 2013, the Company had an immaterial liability related to these restructuring costs. All remaining costs related to the restructuring were paid in the first quarter of 2014.
	The Company recognizes transaction related costs as expense in the period incurred. For the years ended December 31, 2013 and 2012, the Company incurred $0.2 million and $1.9 million, respectively, in transaction related costs.
Revision	Revision
	Certain amounts in the consolidated financial statements of prior year periods have been revised to conform to the current period's presentation with no impact on previously reported operating income or stockholders' equity. Specifically, the gains resulting from the sales of Company-owned stores are presented in "Other (income) expense, net" on the consolidated statements of income and the related cash proceeds are presented in "Other investing activities" as an investing cash inflow on the consolidated statements of cash flows. These gains were previously presented in “Gross profit” on the consolidated statements of income with the related cash proceeds being presented as an operating activity in the consolidated statements of cash flows. Certain other amounts in the consolidated financial statements of prior year periods have been revised to conform to the current period’s presentation. None of these revisions are material to any of the prior year periods.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements
	In June 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") ASU 2014-12, which updates guidance on performance stock awards. The update states that for any award that has a performance target that affects vesting and that could be achieved after the requisite period, that performance target should still be treated as a performance condition. This standard is effective for fiscal years beginning after December 15, 2015. The Company is currently evaluating the impact this guidance will have on the consolidated financial statements.
	In May 2014, the FASB issued ASU 2014-09, which updates revenue recognition guidance relating to contracts with customers. This standard states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This standard is effective for fiscal years beginning after December 15, 2016. The Company is currently evaluating the impact this guidance will have on the consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11 regarding the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This standard requires entities to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss ("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. This ASU requires entities to assess whether to net the unrecognized tax benefit with a deferred tax asset as of the reporting date. This guidance is effective for fiscal years beginning after December 15, 2013, with early adoption permitted. The Company adopted this guidance during the first quarter of 2014, and it did not have a material impact on the consolidated financial statements.
