DERIVATIVE FINANCIAL INSTRUMENTS [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	4. DERIVATIVE FINANCIAL INSTRUMENTS The Company enters into non-designated foreign currency derivatives, primarily comprised of foreign currency forward contracts, for which hedge accounting does not apply. The changes in the fair market value of these non-designated derivatives are included in other income/expense in the Company's consolidated statements of income. The Company uses non-designated foreign currency derivatives to hedge foreign-currency-denominated intercompany transactions and to partially mitigate the impact of foreign-currency fluctuations. The fair value of the non-designated foreign currency derivatives is based on third-party quotes. As of June 30, 2017, the Company did not hold any non-designated derivative contracts. As of June 30, 2016, the Company held non-designated derivative contracts with notional amounts of 500 million Japanese yen ($4.8 million), 11.5 billion Korean won ($10.0 million), 3.9 million Canadian dollars ($3.0 million) and 16.0 million South African rand ($1.1 million). Gains and losses related to non-designated derivative contracts are recorded as part of Other Income (Expense). The following table summarizes gains (losses) related to derivative instruments not designated as hedging instruments during the three- and six-month periods ended June 30, 2017 and 2016 (U.S. dollars in thousands): Derivatives not designated as hedging instruments: Location of Gain (Loss) Recognized in Income Amount of Gain (Loss) Recognized in Income Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Foreign currency contracts Other income (expense) $ -- $ (474 ) $ (485 ) $ (478 ) The Company designates as cash-flow hedges those foreign currency forward contracts it enters to hedge forecasted intercompany transactions that are subject to foreign currency exposures. Changes in the fair value of these forward contracts designated as cash-flow hedges are recorded as a component of accumulated other comprehensive income (loss) within shareholders' equity (deficit), and are recognized in the consolidated statement of income during the period which approximates the time the hedged transaction is settled. As of June 30, 2017, the Company held forward contracts designated as foreign currency cash flow hedges with notional amounts totaling 2.2 billion Japanese yen and 1.0 million Euros ($19.6 million and $1.1 million, respectively), compared to 2.9 billion Japanese yen and 9.0 million euros ($28.1 million and $10.0 million, respectively) as of June 30, 2016, to hedge forecasted foreign-currency-denominated intercompany transactions. The fair value of these hedges were $0.3 million and $(2.9) million as of June 30, 2017 and 2016, respectively. The contracts held at June 30, 2017 have maturities through June 2018, and accordingly, all unrealized gains and losses on foreign currency cash flow hedges included in accumulated other comprehensive loss will be recognized in current earnings over the next 12 months. The following table summarizes gains (losses) related to derivative instruments recorded in other comprehensive income (loss) during the three-month periods ended June 30, 2017 and 2016 (U.S. dollars in thousands): Derivatives designated as hedging instruments: Amount of Gain (Loss) Recognized in Other Comprehensive Loss Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Foreign currency forward contracts related to intercompany license fee, product sales, and selling expense hedges $ 207 $ (1,170 ) $ (180 ) $ (2,860 ) The following table summarizes gains (losses) relating to derivative instruments reclassified from accumulated other comprehensive loss into income during the three- and six-month periods ended June 30, 2017 and 2016 (U.S. dollars in thousands): Derivatives designated as hedging instruments: Location of Gain (Loss) Reclassified from Accumulated Other Comprehensive Loss into Income Amount of Gain (Loss) Reclassified from Accumulated Other Comprehensive Loss into Income Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Foreign currency forward contracts related to intercompany license fees and product sales hedges Revenue $ 134 $ (401 ) $ 109 $ (479 ) Foreign currency forward contracts related to intercompany selling expense hedges Selling expenses $ 269 $ (525 ) $ 228 $ (632 ) As of June 30, 2017 and December 31, 2016, there were $0.2 million and $0.6 million, respectively, of unrealized gains/(losses) included in accumulated other comprehensive loss related to foreign currency cash flow hedges. The remaining $74.9 million and $84.7 million as of June 30, 2017 and December 31, 2016, respectively, in accumulated other comprehensive loss are related to cumulative translation adjustments. The Company assesses hedge effectiveness at least quarterly. During the three- and six- month periods ended June 30, 2017 and 2016, all hedges were determined to be effective. The Company reports its derivatives at fair value as either other current assets or accrued expenses within its consolidated balance sheet. See Note 13 Fair Value.

SEGMENT INFORMATION [Abstract]
SEGMENT INFORMATION	6. SEGMENT INFORMATION As a result of the Company's management changes in the first quarter of 2017, the Company concluded that the Chief Operating Decision Maker, as defined in ASC 280 is now comprised of the CEO, President and CFO. This change required the Company to reevaluate its determination of operating segments. The Company's operating segments are based on geographic regions that generate revenue and hold its long-lived assets. The Company sells and distributes its products through a global network of customers and sales leaders in approximately 50 markets. The Company has divided these markets into seven operating segments, which are the Company's reportable segments: Mainland China, Hong Kong/Taiwan, South Korea, Japan, South Asia/Pacific, Americas and EMEA. The seven reportable segments generate revenue from the sale of personal care products and nutritional supplements under the Nu Skin and Pharmanex brands, have similar business characteristics and align with how the CODM function began assessing performance and allocating resources in the first quarter of 2017. Profitability by segment as reported under US GAAP is driven primarily by the Company's international taxation policies. Segment contribution, which is the Company's segment profitability metric presented in the table below, excludes certain intercompany charges, specifically royalties, license fees, transfer pricing, discrete charges and other miscellaneous items. These charges have been included in Corporate and other expenses. Corporate and other expenses also include costs related to the Company's executive and administrative offices, information technology, research and development, marketing and supply chain functions not recorded at the segment level. The accounting policies of the segments are the same as those described in Note 1 - The Company. The Company evaluates the performance of its segments based on revenue and segment contribution. Each segment records direct expenses related to its employees and its operations. Summarized financial information for the Company's reportable segments is shown in the following tables. Asset information is not reviewed or included with the Company's internal management reporting. Therefore, the Company has not disclosed asset information for each reportable segment.

GOODWILL [Abstract]
GOODWILL	7. GOODWILL During the first quarter of 2017, the Company realigned its operational segments and reporting structure to reflect how the business will be managed going forward. As part of this realignment, the Company divided its single operating segment into seven geographical reporting segments. The Company's reporting units for goodwill are its operating segments, which are also its reportable segments. As a result of the segment changes, the historical goodwill of $115.0 million was allocated to the seven reportable segments.

DEFERRED TAX ASSETS AND LIABILITIES [Abstract]
DEFERRED TAX ASSETS AND LIABILITIES	9. 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. The Company has netted these deferred tax assets and deferred tax liabilities by jurisdiction. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be ultimately realized. As of June 30, 2017 and December 31, 2016, the Company had net deferred tax assets of $30.8 million and $35.1 million, respectively. The Company evaluates its indefinite reinvestment assertions with respect to foreign earnings for each quarter. Other than earnings the Company intends to reinvest indefinitely, the Company accrues for the U.S. federal and state income taxes applicable to the earnings. For all foreign earnings, the Company accrues the applicable foreign income taxes. The Company intends to utilize the offshore earnings to fund foreign investments, specifically capital expenditures. Undistributed earnings that the Company has indefinitely reinvested, for which no federal or state income taxes in the U.S. have been provided, aggregate to $70.0 million as of December 31, 2016. If the amount designated as indefinitely reinvested as of December 31, 2016 was repatriated to the United States, the amount of incremental taxes would be approximately $7.6 million.

UNCERTAIN TAX POSITIONS [Abstract]
UNCERTAIN TAX POSITIONS	10. UNCERTAIN TAX POSITIONS The Company files income tax returns in the U.S. federal jurisdiction, and in various state and foreign jurisdictions. The Company is no longer subject to tax examinations from the IRS for all years for which tax returns have been filed before 2011. With a few exceptions, the Company is no longer subject to state and local income tax examination by tax authorities for the years before 2011. In 2009, the Company entered into a voluntary program with 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 2017 and may elect to continue participating in CAP for future tax years; the Company may withdraw from the program at any time. In major foreign jurisdictions, the Company is generally no longer subject to income tax examinations for years before 2010. However, statutes in certain countries may be as long as ten years for transfer pricing related issues. Along with the IRS examination of 2011, 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. There are potential changes in unrecognized tax benefits from the multiple jurisdictions in which the Company operates, as well as the expiration of various statutes of limitation and possible completion of tax examinations; however, the Company does not anticipate that total unrecognized tax benefits will significantly change over the next 12 months.

COMMITMENTS AND CONTINGENCIES [Abstract]
COMMITMENTS AND CONTINGENCIES	11. COMMITMENTS AND CONTINGENCIES The Company is subject to government regulations pertaining to product formulation, labeling and packaging, product claims and advertising, and 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 sales force is not in compliance with existing statutes, laws, rules or regulations could 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. 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, results of operations or cash flows. The Company and its Subsidiaries are defendants in litigation, investigations and other proceedings involving various matters. In the opinion of the Company's management, based upon advice of its counsel handling such litigation, investigations and other 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.

DEBT [Abstract]
DEBT	12. DEBT Credit Agreement On October 9, 2014, the Company entered into a Credit Agreement (the "Credit Agreement") with various financial institutions, and Bank of America, N.A. as administrative agent. The Credit Agreement provides for a $127.5 million term loan facility, a 6.6 billion Japanese yen term loan facility and a $187.5 million revolving credit facility, each with a term of five years. On October 10, 2014, the Company drew the full amount of the term loan facilities, and as of June 30, 2017 and December 31, 2016, the Company had an outstanding balance of $72.5 million and $47.5 million, respectively, on the revolving credit facility. Any additional amounts drawn under the revolving credit facility will bear interest at rates that will be determined in accordance with the Credit Agreement. The Credit Agreement requires that the Company maintains a consolidated leverage ratio not exceeding 2.25 to 1.00 and a consolidated interest coverage ratio of no less than 3.00 to 1.00. The Company believes these covenants provide it with greater flexibility to pay dividends and repurchase stock. The Company is in compliance with its debt covenants. Convertible Note On June 16, 2016, the Company issued $210.0 million of convertible senior notes (the "Convertible Notes") in a private offering to a Chinese investor (the "Holder"). The Convertible Notes are senior unsecured obligations which will rank equal in right of payment to all senior unsecured indebtedness of the Company, and will rank senior in right of payment to any indebtedness that is contractually subordinated to the Convertible Notes. Interest on the Convertible Notes is payable semiannually in arrears on June 15 and December 15 of each year at a rate of 4.75% per annum. The Convertible Notes mature on June 15, 2020, unless repurchased or converted prior to maturity. Prior to the stated maturity date, the Company may, at its option, redeem all or part of the Convertible Notes at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, provided that its common stock share price is equal to or exceeds 180% of the applicable conversion price for 20 or more trading days (including the final three trading days) in the 30 consecutive trading days prior to the Company's exercise of such redemption right. The Holder of the Convertible Notes may, at its option, cause the Company to repurchase all of such Holder's Convertible Notes or any portion thereof that is equal to $1,000 in principal amount or multiples of $1,000 upon a change in control or a termination of trading of the Company's common stock, as those terms are defined in the indenture governing the Convertible Notes. In addition, each holder of the Convertible Notes shall have the right, at such holder's option, to convert all or any portion thereof that is equal to $1,000 in principal amount or multiples of $1,000 at any time beginning six calendar months following June 16, 2016, at the then-applicable conversion rate. Upon conversion by the Holder, the Convertible Notes will be settled in cash with respect to principal and any accrued and unpaid interest to such date and in the Company's common shares with respect to any additional amounts, based on the applicable conversion rate at such time. The Convertible Notes had an initial conversion rate of 21.5054 common shares per $1,000 principal amount of the Convertible Notes (which is equal to an initial conversion price of approximately $46.50 per common share). Throughout the term of the Convertible Notes, the conversion rate may be adjusted upon the occurrence of certain specified events. Of the $210.0 million in proceeds received from the issuance of the Convertible Notes, $199.1 million was allocated to long-term debt (the "Liability Component") and $10.9 million was allocated to additional paid-in capital (the "Equity Component") within the Company's consolidated balance sheet. The Liability Component was calculated by measuring the fair value of a similar debt instrument that does not have an associated conversion feature. The amount allocated to the Equity Component, which represents the conversion option, was calculated by deducting the fair value of the Liability Component from the par value of the Convertible Notes. The Company determined that the conversion option does not require separate accounting treatment as a derivative instrument because it is both indexed to the Company's own stock and would be classified in stockholders' equity if freestanding. The Equity Component will not be remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the Liability Component over its carrying amount (the "Debt Discount") will be amortized to interest expense over the term of the Convertible Notes. As a result, the Liability Component will be accreted up to the Convertible Notes' $210.0 million face value, resulting in additional non-cash interest expense being recognized within the Company's consolidated statement of income. The effective interest rate on the Convertible Notes is approximately 7.1% per annum. The net carrying amount of the Liability Component is as follows (U.S. dollars in thousands): June 30, 2017 Principal $ 210,000 Unamortized debt discount (conversion option) (8,372 ) Total long-term debt, net 201,628 Unamortized debt discount (issuance costs) (4,791 ) Net carrying amount $ 196,837 The net carrying amount of the Liability Component was recorded to long-term debt within the Company's consolidated balance sheet. The Company incurred approximately $6.6 million of issuance costs related to the issuance of the Convertible Notes. Of the $6.6 million in issuance costs incurred, $6.3 million and $0.3 million were recorded to deferred financing cost and additional paid-in capital, respectively, in proportion to the allocation of the proceeds of the Convertible Notes. The $6.3 million recorded to deferred financing cost on the Company's consolidated balance sheet as a reduction of long-term debt is being amortized over the contractual term of the Convertible Notes using the effective interest method. During the three months ended June 30, 2017, the Company recognized $3.5 million in interest expense related to the Convertible Notes, which included $2.5 million of contractual interest and $1.0 million in amortization of debt issuance costs and in amortization of the Debt Discount. The following table summarizes the Company's debt facilities as of June 30, 2017 and December 31, 2016: Facility or Arrangement Original Principal Amount Balance as of June 30, 2017 (1)(2) Balance as of December 31, 2016 Interest Rate Repayment terms Credit Agreement term loan facility: U.S. dollar denominated: $127.5 million $102.0 million $108.4 million Variable 30 day: 3.98% One half of the principal amount payable in increasing quarterly installments over a five-year period beginning on December 31, 2014, with the remainder payable at the end of the five-year term. Japanese yen denominated: 6.6 billion yen 5.3 billion yen ($46.9 million as of June 30, 2017) 5.6 billion yen ($47.9 million as of December 31, 2016) Variable 30 day: 2.75% One half of the principal amount payable in increasing quarterly installments over a five-year period beginning on December 31, 2014, with the remainder payable at the end of the five-year term.

Korea subsidiary loan: $20.0 million — $10.0 million 1.12% Loan paid in full as of March 2017. Japan subsidiary loan: 2.0 billion yen 1.0 billion yen ($8.9 million as of June 30, 2017) 1.3 billion yen ($11.4 million as of December 31, 2016) 0.66% Payable in semi-annual installments over three years that began on January 31, 2016. Convertible note: $210.0 million $210.0 million $210.0 million 4.75% Principal amount payable on June 15, 2020. (1) As of June 30, 2017, the current portion of the Company's debt (i.e. becoming due in the next 12 months) included $15.1 million of the balance of its U.S. dollar denominated debt under the Credit Agreement facility, $7.0 million of the balance of its Japanese yen-denominated debt under the Credit Agreement facility and $5.9 million of the Japan subsidiary loan. The Company has classified the $72.5 million borrowed under the revolving line of credit as short term because it is the Company's intention to use the line of credit to borrow and pay back funds over short periods of time. (2) The carrying value of the debt reflects the amounts stated in the above table less a debt discount of $11.0 million and debt issuance costs of $4.8 million (consisting of $13.2 million related to the Convertible Note and $2.6 million related to the credit agreement), which is not reflected in this table.

FAIR VALUE [Abstract]
FAIR VALUE	13. FAIR VALUE The carrying value of financial instruments including cash and cash equivalents, accounts receivable and accounts payable approximate fair values due to the short-term nature of these instruments. The Company's current investments as of June 30, 2017 include certificates of deposits and pre-refunded municipal bonds that are classified by management as held-to-maturity as the Company had the positive intent and ability to hold to maturity. The carrying value of these current investments approximate fair values due to the short-term nature of these instruments. The Company has classified these instruments as Level 2 in the fair value hierarchy. Fair value estimates are made at a specific point in time, based on relevant market information. The FASB Codification defines fair value as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. On a quarterly basis, the Company measures at fair value certain financial assets, including cash equivalents. Accounting standards specify a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect data obtained from independent sources, while unobservable inputs reflect the Company's market assumptions. These two types of inputs have created the following fair-value hierarchy: ▪ Level 1 – quoted prices in active markets for identical assets or liabilities; ▪ Level 2 – inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; ▪ Level 3 – unobservable inputs based on the Company's own assumptions. Accounting standards permit companies, at their option, to measure certain financial instruments and other eligible items at fair value. The Company has elected not to apply the fair value option to existing eligible items beyond what is required by US GAAP. The following tables present the fair value hierarchy for those assets and liabilities measured at fair value on a recurring basis (U.S. dollars in thousands): Fair Value at June 30, 2017 Level 1 Level 2 Level 3 Total Financial assets (liabilities): Cash equivalents and current investments $ 33,812 $ — $ — $ 33,812 Other long-term assets 3,463 — — 3,463 Forward contracts — 256 — 256 Life insurance contracts — — 35,627 35,627 Total $ 37,275 $ 256 $ 35,627 $ 73,158 Fair Value at December 31, 2016 Level 1 Level 2 Level 3 Total Financial assets (liabilities): Cash equivalents and current investments $ 50,307 $ — $ — $ 50,307 Other long-term assets 2,782 — — 2,782 Forward contracts — 1,371 — 1,371 Life insurance contracts — — 32,286 32,286 Total $ 53,089 $ 1,371 $ 32,286 $ 86,746 The following table provides a summary of changes in fair value of the Company's Level 3 marketable securities (U.S. dollars in thousands): Life Insurance Contracts Beginning balance at January 1, 2017 $ 32,286 Actual return on plan assets: Relating to assets still held at the reporting date 2,606 Purchases and issuances 895 Sales and settlements (160 ) Transfers into Level 3 -- Ending balance at June 30, 2017 $ 35,627

The objective of this update was to simplify several aspects of the accounting for employee share-based payment transactions, including accounting for income taxes related to share-based compensation, the related classification in the statement of cash-flows, and accounting for share award forfeitures. This ASU was effective for the Company beginning on January 1, 2017 As permitted, the Company elected to classify excess tax benefits as an operating activity in the Statement of Cash Flows instead of as a financing activity on a prospective basis and did not retroactively adjust prior periods. As also permitted by the new guidance, beginning January 1, 2017 the Company has elected to account for share award forfeitures as they occur. Previously, share-based compensation expense was recorded net of estimated forfeitures. A cumulative adjustment of $2.8 million was recorded to retained earnings and additional paid-in capital as of January 1, 2017. Prior periods were not retroactively adjusted. In the second half of 2016, the FASB issued ASU Nos. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments Statement of Cash Flows (Topic 230): Restricted Cash. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . This guidance simplifies the required test of goodwill for impairment by eliminating Step 2 from the goodwill impairment test. If a company determines in Step 1 of the goodwill impairment test that the carrying value of goodwill is less than the fair value, an impairment in that amount should be recorded to the income statement, rather than proceeding to Step 2. This ASU is effective for interim and annual impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

COST OF SALES	15. COST OF SALES In April 2017, the Tokyo High Court issued a ruling on a dispute between the Company and the customs authorities in Japan. The High Court affirmed the Tokyo District Court's February 2016 decision upholding previous customs assessments related to the importation of several of the Company's products into Japan during 2010. The High Court's decision applies only to imports that occurred during 2010; the Company's appeal regarding imports during the other time periods in the dispute is still pending with the High Court. The Company has appealed the High Court's decision to the Japan Supreme Court. As previously disclosed, the Company already recorded a charge of $31.4 million to cost of sales in the first quarter of 2016, when the District Court issued its decision. This was a non-cash item because the Company was previously required to pay the assessments. This charge represents the full amount that was disputed, including assessments for the period of October 2006 through September 2009 in connection with post-importation audits, as well as the disputed portion of our import duties from October 2009 to the date of the District Court's decision.
