Additionally, diluted earnings per share data gives effect to all potentially dilutive common shares that were outstanding during the periods presented. For the three-month periods ended September 30, 2012 and 2011, other stock options totaling 0.2 million and 0.1 million, respectively, and for the nine-month periods ended September 30, 2012 and 2011, other stock options totaling 0.1 million and 2.1 million, respectively, were excluded from the calculation of diluted earnings per share because they were anti-dilutive.

DEFERRED TAX ASSETS AND LIABILITIES	9 Months Ended
DEFERRED TAX ASSETS AND LIABILITIES	Sep. 30, 2012
DEFERRED TAX ASSETS AND LIABILITIES [Abstract]
DEFERRED TAX ASSETS AND LIABILITIES	7. DEFERRED TAX ASSETS AND LIABILITIES The Company accounts for income taxes in accordance with the Income Taxes topic of the Financial Accounting Standards Codification. These standards establish financial accounting and reporting standards for the effects of income taxes that result from an enterprise's activities during the current and preceding years. The Company takes an asset and liability approach for financial accounting and reporting of income taxes. The Company pays income taxes in many foreign jurisdictions based on the profits realized in those jurisdictions, which can be significantly impacted by terms of intercompany transactions between the Company and its foreign affiliates. Deferred tax assets and liabilities are created in this process. As of September 30, 2012 the Company had net deferred tax assets of $49.5 million. The Company nets these deferred tax assets and deferred tax liabilities by jurisdiction. The Company establishes valuation allowances when necessary to reduce deferred tax assets to the amounts expected to be ultimately realized.

UNCERTAIN TAX POSITIONS	9 Months Ended
UNCERTAIN TAX POSITIONS	Sep. 30, 2012
UNCERTAIN TAX POSITIONS [Abstract]
UNCERTAIN TAX POSITIONS	8. UNCERTAIN TAX POSITIONS The Company files income tax returns in the U.S. federal jurisdiction, and in various state and foreign jurisdictions. In 2009, the Company entered into a voluntary program with the United States Internal Revenue Service (the "IRS") called Compliance Assurance Process ("CAP"). The objective of CAP is to contemporaneously work with the IRS to achieve federal tax compliance and resolve all or most of the issues prior to filing of the tax return. The Company has elected to participate in the CAP program for 2013 and may elect to continue participating in CAP for future tax years; the Company may withdraw from the program at any time. During the third quarter of 2011, the Company entered into a closing agreement with the IRS for all adjustments for the 2005 through 2008 tax years. Due to the Company's participation in the IRS CAP program, the Company is no longer subject to US federal income tax examinations for the years before 2009. With a few exceptions, the Company is no longer subject to state and local income tax examination by tax authorities for the years before 2005. In major foreign jurisdictions, the Company is no longer subject to income tax examinations for years before 2006. In addition to its participation in CAP, the Company is currently under examination in certain foreign jurisdictions; however, the outcomes of those reviews are not yet determinable. The Company's unrecognized tax benefits relate to multiple foreign and domestic jurisdictions. Due to potential increases in unrecognized tax benefits from the multiple jurisdictions in which the Company operates, as well as the expiration of various statutes of limitation, it is reasonably possible that the Company's gross unrecognized tax benefits, net of foreign currency adjustments, may change within the next 12 months by a range of approximately $1 to $2 million. The amount of gross unrecognized tax benefits decreased by $1.3 million during the nine months ended September 30, 2012, due mainly to the expiration of various foreign and U.S. statutes of limitation. This decrease was offset by a decrease in corresponding deferred tax assets of $1.5 million for a net increase in liability of $0.3 million.

COMMITMENTS AND CONTINGENCIES	9 Months Ended
COMMITMENTS AND CONTINGENCIES	Sep. 30, 2012
COMMITMENTS AND CONTINGENCIES [Abstract]
COMMITMENTS AND CONTINGENCIES	9. COMMITMENTS AND CONTINGENCIES The Company is subject to governmental regulations pertaining to product formulation, labeling and packaging, product claims and advertising and to the Company's direct selling system. The Company is also subject to the jurisdiction of numerous foreign tax and customs authorities. Any assertions or determination that either the Company or the Company's distributors is not in compliance with existing statutes, laws, rules or regulations could potentially have a material adverse effect on the Company's operations. In addition, in any country or jurisdiction, the adoption of new statutes, laws, rules or regulations or changes in the interpretation of existing statutes, laws, rules or regulations could have a material adverse effect on the Company and its operations. Although management believes that the Company is in compliance in all material respects with the statutes, laws, rules and regulations of every jurisdiction in which it operates, no assurance can be given that the Company's compliance with applicable statutes, laws, rules and regulations will not be challenged by foreign authorities or that such challenges will not have a material adverse effect on the Company's financial position or results of operations or cash flows. The Company and its Subsidiaries are defendants in litigation and proceedings involving various matters. Except as noted below, in the opinion of the Company's management, based upon advice of its counsel handling such litigation and proceedings, adverse outcomes, if any, will not likely result in a material effect on the Company's consolidated financial condition, results of operations or cash flows. The Company is subject to regular audits by federal, state and foreign tax authorities. These audits may result in additional tax liabilities. The Company believes it has appropriately provided for income taxes for all years. Several factors drive the calculation of its tax reserves. Some of these factors include: (i) the expiration of various statutes of limitations; (ii) changes in tax law and regulations; (iii) issuance of tax rulings; and (iv) settlements with tax authorities. Changes in any of these factors may result in adjustments to the Company's reserves, which would impact its reported financial results. The Company is currently involved in a dispute with customs authorities in Japan with respect to duty assessments on several of the Company's Pharmanex nutritional products, which is separate and distinct from the dispute discussed in Note 12. The dispute relates to additional customs assessments made by Yokohama Customs for the period of October 2006 through September 2009 in connection with post-importation audits, as well as the disputed portion of the Company's import duties from October 2009 to the present, which the Company has or will hold in bond or pay under protest. The aggregate amount of these assessments and disputed duties was approximately 4.3 billion Japanese yen as of September 30, 2012 (approximately $55.4 million), net of any recovery of consumption taxes. Additional assessments related to any prior period would be barred by applicable statutes of limitations. The issue in this case is whether a United States entity utilizing a commissionaire agent in Japan to import its products can use the manufacturer's invoice or must use another valuation method, and, if an alternative method must be used, what the allowable deductions would be in determining the proper valuation. Following the Company's review of the assessments and after consulting with the Company's legal and customs advisors, the Company believes that the additional assessments are improper and are not supported by applicable customs laws. The Company filed letters of protest with Yokohama Customs, which were rejected. The Company then appealed the matter to the Ministry of Finance in Japan. In May 2011, the Company received notice that the Ministry of Finance in Japan denied the Company's administrative appeal. The Company disagrees with the Ministry of Finance's administrative decision. The Company is now pursuing the matter in Tokyo District Court, which the Company believes will provide a more independent determination of the matter. In addition, the Company is currently being required to post a bond or make a deposit equal to the difference between the Company's declared duties and the amount the customs authorities have determined the Company should be paying on all current imports. Because the Company believes that the assessment of higher duties by the customs authorities is an improper application of the regulations, the Company is currently expensing the portion of the duties the Company believes is supported under applicable customs law, and recording the additional deposit or payment as a receivable within long-term assets on its consolidated financial statements. If the Company is unsuccessful in recovering the amounts assessed and paid or held in bond, the Company will likely be required to record a non-cash expense for the full amount of the disputed assessments. The Company anticipates that additional disputed duties will be reduced going forward as the Company now purchases a majority of the affected products in Japan from a Japanese company that purchases and imports the products from the manufacturer.

ACCOUNTING PRONOUNCEMENTS	Sep. 30, 2012
Accounting Pronouncements [Abstract]
Accounting Pronouncements	11. ACCOUNTING PRONOUNCEMENTS In May 2011, the FASB issued ASU 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. ASU 2011-04 provides a consistent definition of fair value and ensures that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. The adoption of ASU 2011-04 did not have a significant impact on the Company's financial statements. In June 2011, the FASB issued ASU 2011-05 as amended by ASU 2011-12, Presentation of Comprehensive Income. ASU 2011-05 requires entities to present items of net income and other comprehensive income either in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive, statements of net income and other comprehensive income. Beginning with the three months ended March 31, 2012, the Company provided the required financial reporting presentation pursuant to ASU 2011-05 and ASU 2011-12 herein. In September 2011, the FASB ratified ASU No. 2011-08, Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment. ASU 2011-08 allows an entity the option of performing a qualitative assessment before calculating the fair value of its reporting units. If, based on the qualitative assessment, an entity concludes it is more likely than not that the fair value of the reporting unit exceeds its carrying value, quantitative testing for impairment is not necessary. The adoption of ASU No. 2011-08, effective January 1, 2012, had no impact on the Company's consolidated financial statements. In July 2012, the FASB issued ASU No. 2012-02, Intangibles-Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. The standard gives companies the option to perform a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired rather than calculating the fair value of the indefinite-lived intangible asset. It is effective prospectively for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The adoption of ASU No. 2012-02 will not have a material impact on the Company's consolidated financial statements.

12.	COST OF SALES

In March 2011, the Tokyo District Court upheld a disputed $32.8 million customs assessment on certain of the Company's products imported into Japan during the period of October 2002 through July 2005. As a result of this decision, the Company recorded an expense for the full amount of the disputed assessments in the first quarter of 2011. The charge was a non-cash item, as the Company was previously required to pay the assessments. The Company has appealed this decision and currently anticipates a decision on the appeal by the end of 2012.
