Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Consolidation

The consolidated financial statements include the accounts of the Company and the Subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation.

Use of estimates

The preparation of these financial statements, in conformity with accounting principles generally accepted in the United States of America, required management to make estimates and assumptions that affected the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results may differ from these estimates.

Cash and cash equivalents

Cash equivalents are short-term, highly liquid instruments with original maturities of 90 days or less.

Inventories

Inventories consist primarily of merchandise purchased for resale and are stated at the lower of standard cost or market, using a standard cost method which approximates the first-in, first-out method. The Company had adjustments to its inventory carrying value totaling $56.0 million and $20.7 million as of December 31, 2014 and 2015, respectively. During the second quarter of 2014, the Company made a determination to adjust its inventory carrying value. Heightened media and regulatory scrutiny in Mainland China in the first part of 2014, and the voluntary actions the Company took in response to such scrutiny, had a negative impact on the size of the Company's limited-time offer in June 2014, which significantly reduced its expectations for plans to sell ageLOC TR90 in a limited-time offer later in 2014 or the beginning of 2015. This resulted in a $50.0 million write-down of estimated surplus inventory primarily in Mainland China. The Company similarly incurred a $37.9 million write-down of estimated surplus inventory primarily in the Greater China region in the third quarter of 2015 due to reduced expectations for future product sales.

Ending balance, adjustments to inventory carrying value	$	5,934		$	56,034		$	20,744

Property and equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation is recorded using the straight-line method over the following estimated useful lives:

	Buildings		39 years
	Furniture and fixtures		5 - 7 years
	Computers and equipment		3 - 5 years
	Leasehold improvements		Shorter of estimated useful life or lease term
	Scanners		3 years
	Vehicles		3 - 5 years

Expenditures for maintenance and repairs are charged to expense as incurred. When an asset is sold or otherwise disposed of, the cost and associated accumulated depreciation are removed from the accounts and the resulting gain or loss is recognized in the statement of income. Property and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. An impairment loss is recognized if the carrying amount of the asset exceeds its fair value.

Goodwill and other intangible assets

Goodwill is recorded when the cost of acquired businesses exceeds the fair value of the identifiable net assets acquired. Goodwill and intangible assets with indefinite useful lives are not amortized, but are assessed for impairment annually on June 30. In addition, impairment testing is conducted when events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Goodwill and intangible assets with indefinite useful lives would be written down to fair value if considered impaired. Guidance under Accounting Standards Codification ("ASC") 350, Intangibles - Goodwill and Other, requires an entity to test goodwill for impairment on at least an annual basis. The Company had the option to perform a qualitative assessment to determine whether further impairment testing is necessary or to perform a quantitative assessment by comparing the fair value of a reporting unit to its carrying amount, including goodwill. Under the qualitative assessment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. If under the quantitative assessment the fair value of a reporting unit is less than its carrying amount, then the amount of the impairment loss, if any, must be measured. The Company used the quantitative assessment for all periods presented. Intangible assets with finite useful lives are amortized to their estimated residual values over such finite lives using the straight-line method and reviewed for impairment whenever events or circumstances warrant such a review.

NU SKIN ENTERPRISES, INC.

Notes to Consolidated Financial Statements

No impairment charges were recorded for goodwill or intangibles during the periods presented.

Revenue recognition

Revenue is recognized when products are shipped, which is when title and risk of loss pass to the purchaser of the products. A reserve for product returns is accrued based on historical experience totaling $10.1 million and $7.8 million as of December 31, 2014 and 2015, respectively. During the years ended December 31, 2013, 2014 and 2015, the Company recorded sales returns of $79.4 million, $83.6 million and $65.6 million, respectively. The Company generally requires cash or credit card payment at the point of sale. Accounts receivable generally represents amounts due from credit card companies and are generally collected within a few days of the purchase. As such, the Company has determined that no allowance for doubtful accounts is necessary. Amounts received prior to shipment of products and title passage to the purchaser of the products are recorded as deferred revenue. The Company's sales compensation plans generally do not provide rebates or selling discounts for purchasing its products and services. The Company classifies selling discounts and rebates, if any, as a reduction of revenue at the time the sale is recorded.

Through the Company's product subscription and loyalty programs, which can vary from market to market, participants who commit to purchases on a monthly basis receive a discount from suggested retail or wholesale prices, as applicable. The Company applies this discount at the time of each purchase and not through a larger discount on the initial purchase. Participants may cancel their commitment at any time, however some markets charge a one-time early cancellation fee. All purchases under these programs are subject to the Company's standard product payment and return policies. In accordance with ASC 605-50, the Company classifies selling discounts and rebates, as a reduction of revenue at the time the sale is recorded.

Shipping and handling costs

Shipping and handling costs are recorded as cost of sales and are expensed as incurred.

Advertising expenses

Advertising costs are expensed as incurred. Advertising expense incurred for the years ended December 31, 2013, 2014 and 2015 totaled $11.3 million, $19.6 million and $11.0 million, respectively.

Selling expenses

Selling expenses are the Company's most significant expense and are classified as operating expenses. Selling expenses include distributor commissions as well as wages, benefits, bonuses and other labor and unemployment expenses the Company pays to its sales force in Mainland China. In each of the Company's markets, except Mainland China, Sales Leaders can earn "multi-level" compensation under the Company's global sales compensation plan, including commissions for product sales to their consumer groups as well as the product sales made through the sales network they have developed and trained. The Company does not pay commissions on sales materials.

NU SKIN ENTERPRISES, INC.

Notes to Consolidated Financial Statements

Outside of Mainland China, the Company's distributors may make profits by purchasing the products from the Company at a discount and selling them to consumers with a mark-up. The Company does not account for nor pay additional commissions on these mark-ups received by distributors. In many markets, the Company also allows individuals who are not members of its sales force, referred to as "preferred customers," to buy products directly from the Company at a discount. The Company pays commissions on preferred customer purchases to the referring member of its sales force.

Research and development

Research and development costs are expensed as incurred and are included in general and administrative expenses in the accompanying consolidated statements of income and totaled $18.0 million, $18.9 million and $20.1 million in 2013, 2014 and 2015, respectively.

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.

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 except for 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 2016 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.

Notes to Consolidated Financial Statements

A reconciliation of the beginning and ending amount of unrecognized tax benefits included in other liabilities is as follows (U.S. dollars in thousands):

	2013			2014			2015

Gross balance at January 1	$	9,045		$	7,484		$	5,987
Increases related to prior year tax positions	─			─				1,677
Increases related to current year tax positions		1,188			2,700			1,119
Settlements		(1,671	)	─			─
Decreases due to lapse of statutes of limitations		(1,086	)		(4,106	)		(667	)
Currency adjustments		8			(91	)		(344	)
Gross balance at December 31	$	7,484		$	5,987		$	7,772

At December 31, 2015, the Company had $7.8 million in unrecognized tax benefits of which $0.9 million, if recognized, would affect the effective tax rate. In comparison, at December 31, 2014, the Company had $6.0 million in unrecognized tax benefits of which $1.1 million, if recognized, would affect the effective tax rate. 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 increase within the next 12 months by a range of approximately $0 to $1 million.

During the years ended December 31, 2013, 2014 and 2015, the Company recognized $(0.1) million, $0.4 million and $0.4 million, respectively in interest and penalties expenses/(benefits). The Company had $0.9 million, $1.3 million and $1.7 million of accrued interest and penalties related to uncertain tax positions at December 31, 2013, 2014 and 2015, respectively. Interest and penalties related to uncertain tax positions are recognized as a component of income tax expense.

Net income per share

Net income per share is computed based on the weighted-average number of common shares outstanding during the periods presented. Additionally, diluted earnings per share data gives effect to all potentially dilutive common shares that were outstanding during the periods presented (Note 11).

Foreign currency translation

A significant portion of the Company's business operations occur outside of the United States. The local currency of each of the Company's Subsidiaries is considered its functional currency, except for the Company's subsidiaries in Singapore and Venezuela where the U.S. dollar is used. All assets and liabilities are translated into U.S. dollars at exchange rates existing at the balance sheet dates, revenue and expenses are translated at weighted-average exchange rates and stockholders' equity is recorded at historical exchange rates. The resulting foreign currency translation adjustments are recorded as a separate component of stockholders' equity in the consolidated balance sheets and transaction gains and losses are included in other income and expense in the consolidated financial statements. Net of tax, the accumulated other comprehensive income related to the foreign currency translation adjustments are $47.6 million (net of tax of $10.4 million), $52.6 million (net of tax of $10.8 million) and $71.6 million (net of tax of $10.9 million), at December 31, 2013, 2014 and 2015, respectively.

Classification of Venezuela as a Highly Inflationary Economy and Devaluation of Its Currency

The Company commenced operations in Venezuela in 2007, where it markets a variety of personal care and nutritional products. Total assets in Venezuela as of December 31, 2014 and 2015 are $14.6 million and $7.9 million, of which $8.2 million and $4.3 million are monetary assets in each year, respectively. The Venezuela subsidiary also had a $34.8 million and $33.7 million intercompany balance to its parent company as of December 31, 2014 and 2015, respectively, with respect to charges for inventory, commissions, license fees and service fees. The Company imports all of its products into Venezuela from the United States. Venezuela represents a very small portion of the Company's overall business with sales during 2013, 2014 and 2015 representing approximately 1.1%, 1.0% and 0.2% of the Company's overall revenue, respectively.

Since 2010, Venezuela has been considered a highly inflationary economy. A country is considered to have a highly inflationary economy if it has a cumulative inflation rate of approximately 100% or more over a three-year period as well as other qualitative factors including historic inflation rate trends (increasing and decreasing), the capital intensiveness of the operation and other pertinent economic factors. The functional currency in highly inflationary economies is required to be the functional currency of the entity's parent company (which for our Venezuela subsidiary is the U.S. dollar), and transactions denominated in the local currency are remeasured to the functional currency. The remeasurement of bolivars into U.S. dollars creates foreign currency transaction gains or losses, which the Company includes in its consolidated statement of income.

The Venezuela subsidiary did not transition to highly inflationary status until the first quarter of 2014. As a result, the Company continued to account for the Venezuela subsidiary as a bolivar functional currency entity, rather than a U.S. dollar functional currency entity. In the first quarter of 2014, the Company began to account for this subsidiary as highly inflationary, and therefore changed the functional currency of the entity to the U.S. dollar. The consolidated statement of income for the year ended December 31, 2014, includes an out-of-period adjustment of $6.3 million to correct this error as it was not deemed to be material to the current or prior period financial statements.

During the first quarter of 2014, two new foreign exchange mechanisms ("SICAD I" and "SICAD II") became available in Venezuela. As of March 31, 2014, the Company determined it would be most appropriate for it to utilize the SICAD I rate, which was approximately 10.7 bolivars per U.S. dollar. As a result of the adoption of this rate during the period ended March 31, 2014, the Company recorded a $14.7 million charge in Other Income (Expense) to reflect foreign currency transaction losses on its net monetary assets denominated in bolivar, which is reflected in the year ended December 31, 2014.

As of June 30, 2014, the Company determined that it would be most appropriate for it to utilize the SICAD II rate, which was approximately 50 bolivars per U.S. dollar, as the Company had not been successful in getting approval under SICAD I and believed the SICAD II rate better reflects the rate at which the Company will be able to convert bolivars to U.S. dollars. As a result of the adoption of this rate during the three months ended June 30, 2014, the Company recorded an additional $25.3 million charge in Other Income (Expense) to reflect additional foreign currency translation losses on its net monetary assets denominated in bolivar, which is reflected in the year ended December 31, 2014.

In the first quarter of 2015, a new foreign exchange mechanism ("SIMADI") was announced, which utilizes a variable exchange rate that was approximately 193 bolivars per U.S. dollar. As a result of this new exchange mechanism, in 2015, the Company recorded charges totaling $10.2 million in other income (expense) to reflect additional foreign currency translation losses on its net monetary assets denominated in bolivars.

Notes to Consolidated Financial Statements

The current operating environment in Venezuela continues to be challenging, with high inflation in the country, government restrictions on foreign exchange and pricing controls, and the possibility of the government announcing further devaluations to its currency. Currency restrictions enacted by the Venezuelan government have impacted the ability of the Company to exchange foreign currency at the official rate to pay for imported products, license fees, commissions and other service fees. The Company has been unsuccessful in obtaining U.S. dollars at the official exchange rates and under alternative exchange mechanisms described below. As a result, these foreign exchange controls in Venezuela have limited the Company's ability to repatriate earnings and settle the Company's intercompany obligations, which has resulted in the accumulation of bolivar-denominated cash and cash equivalents in Venezuela.

Fair value of financial instruments

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 December 31, 2015 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. As of December 31, 2014 and 2015, the long-term debt fair value is $252.8 million and $252.4 million, respectively. The estimated fair value of the Company's debt is based on interest rates available for debt with similar terms and remaining maturities. 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 many financial instruments and certain other items at fair value. The Company has elected not to apply the fair value option to existing eligible items.

Stock-based compensation

All share-based payments, including grants of stock options and restricted stock units, are required to be recognized in our financial statements based upon their respective grant date fair values. The Black-Scholes option-pricing model is used to estimate the fair value of stock options. The determination of the fair value of stock options is affected by our stock price and a number of assumptions, including expected volatility, expected life, risk-free interest rate and expected dividends. We use historical volatility as the expected volatility assumption required in the Black-Scholes model. The expected life of the stock options is based on historical data trended into the future. The risk-free interest rate assumption is based on observed interest rates appropriate for the expected terms of our stock options. The fair value of our restricted stock units is based on the closing market price of our stock on the date of grant less our expected dividend yield. We recognize stock-based compensation net of any estimated forfeitures over the requisite service period of the award.

The total compensation expense related to equity compensation plans was $32.6 million, $17.5 million and $7.4 million for the years ended December 31, 2013, 2014 and 2015, respectively. In 2014 and 2015, these amounts reflect the reversal of $4.7 million and $7.6 million, respectively, for certain performance based awards that were no longer expected to vest. For the years ended December 31, 2013, 2014 and 2015, all stock-based compensation expense was recorded within general and administrative expenses.

Reporting comprehensive income

Comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, and it includes all changes in equity during a period except those resulting from investments by owners and distributions to owners.

Accounting for derivative instruments and hedging activities

The Company recognizes all derivatives as either assets or liabilities, with the instruments measured at fair value.

Portions of the Company's Japanese yen borrowings prior to its October 2014 refinancing were designated, and were effective as, economic hedges of the net investment in its foreign operations. Accordingly, foreign currency transaction gains or losses due to spot rate fluctuations on these debt instruments were included in foreign currency translation adjustments within other comprehensive income. Included in the cumulative translation adjustment are $10.5 million of pretax net losses, $1.4 million of pretax net gains and zero pretax net gains for the years ended December 31, 2013, 2014 and 2015, respectively, from Japanese yen borrowings.

Additionally, the Company's Subsidiaries enter into significant transactions with each other and third parties that may not be denominated in the respective Subsidiaries' functional currencies. The Company regularly monitors its foreign currency risks and seeks to reduce its exposure to fluctuations in foreign exchange rates using foreign currency exchange contracts and through certain intercompany loans of foreign currency.

Hedge effectiveness is assessed at inception and throughout the life of the hedge to ensure the hedge qualifies for hedge accounting treatment. Changes in fair value associated with hedge ineffectiveness, if any, are recorded in the results of operations currently. In the event that an anticipated transaction is no longer likely to occur, the Company recognizes the change in fair value of the derivative in its results of operations currently.

NU SKIN ENTERPRISES, INC.

Notes to Consolidated Financial Statements

Changes in the fair value of derivatives are recorded in current earnings or accumulated other comprehensive loss, depending on the intended use of the derivative and its resulting designation. The gains and losses in accumulated other comprehensive loss stemming from these derivatives will be reclassified into earnings in the period during which the hedged forecasted transaction affects earnings. The fair value of the receivable and payable amounts related to these unrealized gains and losses is classified as other current assets and liabilities. The Company does not use such derivative financial instruments for trading or speculative purposes. Gains and losses on certain intercompany loans of foreign currency are recorded as other income and expense in the consolidated statements of income.

Recent accounting pronouncements

In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This ASU changes the threshold for a disposal to qualify as a discontinued operation. To be considered a discontinued operation, a disposal now must represent a strategic shift that has or will have a major effect on an entity's operations and financial results. This ASU also requires new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. This update will be applied prospectively and was effective for annual periods, and interim periods within those years, beginning after December 15, 2014. The adoption of this standard did not have a material impact on the Company's financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company 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 ASU is effective for annual periods beginning after December 15, 2017 and shall be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the potential impact of this adoption on its consolidated financial statements.

In June 2014, the FASB issued ASU No. 2014-12, Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force). This ASU clarifies that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. This ASU is effective for annual periods, and interim periods within those years, beginning after December 15, 2015. Early adoption is permitted. This ASU may be applied either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

Notes to Consolidated Financial Statements

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements — Going Concern (Subtopic 205-40). The purpose of this ASU is to incorporate into U.S. GAAP management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern within one year after the date that the financial statements are issued, and to provide related footnote disclosures. This update is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This guidance requires that debt issuance costs be presented as a direct reduction to the carrying amount of the related debt in the balance sheet rather than as a deferred charge, consistent with the presentation of discounts on debt. ASU 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs associated with Line-of-Credit Arrangements, was issued in August 2015 to clarify that the U.S. Securities and Exchange Commission ("SEC") staff would not object to an entity deferring and presenting debt issuance costs related to a line-of-credit arrangement as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The guidance is effective for fiscal years beginning after December 15, 2015, and is to be applied retrospectively. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on the Company's consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This guidance requires an entity to measure inventory at the lower of cost and net realizable value, rather than at the lower of cost or market. The guidance is effective for interim and annual periods beginning after December 15, 2016, and is to be applied prospectively. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on the Company's consolidated financial statements.

In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. This guidance requires entities to classify deferred tax liabilities and assets as noncurrent in a classified statement of financial position. The guidance is effective for interim and annual periods beginning after December 15, 2016, and may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. As permitted, the Company elected to early adopt this guidance effective December 31, 2015, and has applied the guidance prospectively. As of December 31, 2014, the Company had $40.8 million of current deferred tax assets and no current deferred tax liabilities which remain classified as current in the consolidated balance sheet. The adoption of this guidance did not have a significant impact on the Company's consolidated financial statements, other than the prospective classification of deferred tax liabilities and assets as long-term in accordance with the new presentation requirements. There was no impact on the Company's results of operations as a result of the adoption of ASU 2015-17.

In the year ended December 31, 2015, the Company wrote-off approximately $12.0 million of fully amortized intangible assets.

All of the Company's goodwill is based in the U.S. Goodwill and indefinite life intangible assets are not amortized, rather they are subject to annual impairment tests. Annual impairment tests were completed resulting in no impairment charges for any of the periods shown. Finite life intangibles are amortized over their useful lives unless circumstances occur that cause the Company to revise such lives or review such assets for impairment.

Long-Term Debt [Abstract]

Long-Term Debt

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 December 31, 2014 and 2015, the Company had outstanding balances of $72.5 million and $47.5 million 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.

The following table summarizes the Company's debt facilities as of December 31, 2014 and 2015:

Facility or Arrangement	Original Principal Amount	Balance as of December 31, 2014	Balance as of December 31, 2015⁽¹⁾⁽²⁾	Interest Rate	Repayment terms

Credit Agreement term loan facility:

U.S. dollar denominated:	$127.5 million	$125.9 million	$118.7 million	Variable 30 day: 2.4815%	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	6.5 billion yen ($54.4 million as of December 31, 2014)	6.1 billion yen ($51.1 million as of December 31, 2015)	Variable 30 day: 2.30%	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.

Credit Agreement revolving credit facility:

		$72.5 million	$47.5 million	Variable 30 day: 2.4815%	Revolving line of credit expires October 2019.

Korean subsidiary loan:	$20.0 million	─	$20.0 million	1.12%	One half of the principal amount payable on March 17, 2017 and the remainder payable on March 16, 2018.

Japan subsidiary loan:	2.0 billion yen	─	2.0 billion yen ($16.6 million as of December 31, 2015)	0.66%	Payable in semi-annual installments over three years that began on January 31, 2016.

⁽¹⁾

As of December 31, 2015, the current portion of the Company's debt (i.e. becoming due in the next 12 months) included $57.8 million of the balance of its U.S. dollar denominated debt under the Credit Agreement facility, $4.5 million of the balance of its Japanese yen-denominated debt under the Credit Agreement facility and $5.5 million of the Japan subsidiary loan. The Company has classified the amounts 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 $4.3 million, which is not reflected in this table.

Lease and Financing Obligations [Abstract]

Lease and Financing Obligations

10. Lease and Financing Obligations

In 2014, the Company's subsidiary in South Korea entered into a lease agreement (the "Lease") with a third-party landlord for a new regional headquarters. As part of the Lease, the landlord agreed to renovate an existing building (the "Existing Building") and construct a new building (the "New Building") adjacent to the Existing Building. The Lease provided that when such renovations and construction were completed, the Company and the landlord would enter into a new lease agreement (the "New Lease") for the Existing Building and the New Building. In April 2015, the Company and the landlord entered into the New Lease on terms generally consistent with the 2014 lease. The New Lease term is for the period May 1, 2015 through April 30, 2025, with an option to extend the agreement for 10 years.

The Company accounts for its lease of the Existing Building as an operating lease. As an inducement to enter into the Lease, the landlord agreed to make certain improvements on behalf of the Company to the Existing Building. The improvements have been accounted for by the Company as a tenant incentive.

The Company has concluded that it is the deemed owner (for accounting purposes only) of the New Building during the construction period under build-to-suit lease accounting. Construction of the New Building began in June 2014 and was completed in June 2015. During the construction period, the Company recorded estimated project construction costs as a construction in progress asset in "Property and equipment, net" and a corresponding long-term liability in "Other liabilities," respectively, in its consolidated balance sheets. In addition, the amounts that the Company has paid or incurred for normal tenant improvements were also recorded to the construction-in-progress asset.

Notes to Consolidated Financial Statements

At the end of the construction period in June 2015, the Company concluded that the New Lease of the New Building did not meet "sale-leaseback" criteria; therefore, the asset and obligation recognized during construction will remain recorded in the Company's consolidated balance sheets. As of December 31, 2015, the completed building and normal tenant improvements under the lease have been reclassified from construction in progress to buildings and leasehold improvements, respectively. The Company accounts for the New Lease of the New Building as a financing with the associated lease payments allocated between the New Building and the underlying parcel of land on a relative fair value basis. Rent expense attributed to the underlying parcel of land, and representing the imputed cost to lease the land, is accounted for on a straight-line basis as the land element is an operating lease.

Lease payments attributed to the New Building are allocated between principal and interest expense using the effective interest method. The principal portion of the lease payment attributed to the New Building is reflected as a principal reduction of the financing obligation. In addition, the asset, which represents the total estimated cost of construction of the New Building at the end of the construction period, is being depreciated over the initial ten-year term of the New Lease to its expected residual value. At the conclusion of the New Lease, the Company will de-recognize both the net book value of the asset and the unamortized portion of the financing obligation. The amount of asset depreciation and financing obligation amortization is structured at the outset such that the remaining residual book value of the asset is equal to the remaining financing obligation at the end of the lease term.

At December 31, 2014, the Company had recognized $13.1 million in estimated project costs associated with the construction of the New Building as part of construction-in-progress and a financing obligation in the amount of $10.4 million, net of a $2.7 million deposit paid directly to the landlord, as part of Other liabilities in its consolidated balance sheet. As of December 31, 2015, the Company had recognized $19.9 million as the value of the New Building offset by accumulated depreciation of $0.3 million and a financing obligation in the amount of $10.6 million, net of a $9.3 million deposit paid directly to the landlord, as part of Other liabilities in its consolidated balance sheet.

As of December 31, 2014, the tenant incentive asset and deferred tenant incentive liability associated with the Existing Building each totaled $6.4 million. As of December 31, 2015, the tenant incentive asset and deferred tenant incentive liability associated with the Existing Building totaled $5.6 million and $5.1 million, respectively.

Notes to Consolidated Financial Statements

In addition to the lease arrangements described above, the Company leases office space and computer hardware under noncancelable long-term operating leases. Most leases include renewal options of at least three years.

Minimum future operating leases and financing obligations at December 31, 2015 are as follows (U.S. dollars in thousands):

Year Ending December 31,	Operating Leases		Financing Obligations

2020		8,927		709
Thereafter		1,921		3,290
Total minimum lease payments	$	117,867	$	6,636

Rent expense for operating leases totaled $34.6 million, $52.3 million, and $52.4 million for the years ended December 31, 2013, 2014 and 2015, respectively. Interest expense associated with the financing obligations was nil for the years ended December 31, 2013 and 2014 and $0.1 million for the year ended December 31, 2015.

Notes to Consolidated Financial Statements

For the years ended December 31, 2013, 2014 and 2015, other stock options totaling 1.2 million, 2.7 million and 1.8 million, respectively, were excluded from the calculation of diluted earnings per share because they were anti-dilutive.

Repurchases of common stock

In 1998, the Company's board of directors approved a stock repurchase plan authorizing the Company to repurchase $10.0 million of its outstanding shares of Class A common stock on the open market or in private transactions. The Company's board from time to time increased the amount authorized under the 1998 stock repurchase plan, including an increase of $400.0 million announced in August 2013. In October 2015, the Company's board terminated the 1998 stock repurchase plan and approved a new repurchase plan with an initial authorization amount of $500.0 million. The repurchases are used primarily to offset dilution from our equity incentive plans and for strategic initiatives. During the years ended December 31, 2013, 2014 and 2015, the Company repurchased 1.7 million, 0.8 million and 3.8 million shares of Class A common stock for an aggregate price of $140.9 million, $45.7 million and $164.1 million, respectively. At December 31, 2015, $446.9 million was available for repurchases under the 2015 stock repurchase plan.

Stock Based Compensation [Abstract]

Stock Based Compensation

12. Stock–Based Compensation

At December 31, 2015, the Company had the following stock-based employee compensation plans:

Equity Incentive Plans

In April 2010, the Company's Board of Directors approved the Nu Skin Enterprises, Inc. 2010 Omnibus Incentive Plan (the "2010 Omnibus Incentive Plan"). This plan was approved by the Company's stockholders at the Company's 2010 Annual Meeting of Stockholders held in May 2010. The 2010 Omnibus Incentive Plan provides for granting of a variety of equity based awards including stock options, stock appreciation rights, restricted stock, restricted stock units, other share based awards, performance cash, performance shares and performance units to executives, other employees, independent consultants and directors of the Company and its subsidiaries. Options granted under the 2010 Omnibus Incentive Plan are generally non-qualified stock options, but the 2010 Omnibus Incentive Plan permits some stock options granted to qualify as "incentive stock options" under the U.S. Internal Revenue Code. The exercise price of a stock option generally is equal to the fair market value of the Company's common stock on the stock option grant date. The contractual term of a stock option granted under the 2010 Omnibus Incentive Plan is seven years. Currently, all shares issued upon the exercise of stock options are from the Company's treasury shares. Subject to certain adjustments, 7.0 million shares were authorized for issuance under the 2010 Omnibus Incentive Plan. On June 3, 2013, the Company's stockholders approved an Amended and Restated 2010 Omnibus Incentive Plan, which among other things increased the number of shares available for awards by 3.2 million shares.

In November 2010, the compensation committee of the board of directors approved the grant of performance stock options to certain key employees under the 2010 Omnibus Incentive Plan. Vesting for the options is performance based, with the options vesting in three installments if the Company's earnings per share equal or exceed the three established performance levels, measured in terms of diluted earnings per share. One third of the options will vest upon earnings per share meeting or exceeding the first performance level, one third of the options will vest upon earnings per share meeting or exceeding the second performance level and one third of the options will vest upon earnings per share meeting or exceeding the third performance level. During the second quarter of 2012, first quarter of 2013 and third quarter of 2013 the first, second and third performance levels were fully achieved.

NU SKIN ENTERPRISES, INC.

Notes to Consolidated Financial Statements

In July 2013, the compensation committee of the board of directors approved the grant of performance stock options to certain key employees under the Amended and Restated 2010 Omnibus Incentive Plan. Vesting for the options is performance based, with the options vesting in four installments if the Company's earnings per share equal or exceed the four established performance levels, measured in terms of diluted earnings per share. One fourth of the options will vest upon earnings per share meeting or exceeding the first performance level, one fourth of the options will vest upon earnings per share meeting or exceeding the second performance level, one fourth of the options will vest upon earnings per share meeting or exceeding the third performance level and one fourth of the options will vest upon earnings per share meeting or exceeding the fourth performance level. The unvested options will terminate upon the Company's failure to meet certain performance thresholds for each of years 2013 through 2019. In addition, all unvested options will terminate on March 30, 2020. The Company records an expense each period for the estimated amount of expense associated with the Company's projected achievement of the performance based targets. The Company recognized $23.2 million of expense, $5.2 million of expense and $6.4 million of income related to these awards in 2013, 2014 and 2015, respectively. The amounts in 2014 and 2015 reflect the reversal of stock compensation for awards no longer expected to vest.

The Company has also issued other performance-based awards to a limited number of participants that similarly vest, or become eligible for vesting, upon achievement of various performance targets.

The fair value of stock option awards was estimated using the Black-Scholes option-pricing model with the following assumptions and weighted-average fair values as follows:

	December 31,
Stock Options:	2013		2014		2015

Weighted average grant date fair value of grants	$	22.10	$	23.01	$	16.26
Risk-free interest rate⁽¹⁾		1.4%		1.7%		1.7%
Dividend yield⁽²⁾		3.1%		1.9%		2.1%
Expected volatility⁽³⁾		41.7%		45.4%		46.8%
Expected life in months⁽⁴⁾	62 months		62 months		65 months

⁽¹⁾

The risk-free interest rate is based upon the rate on a zero coupon U.S. Treasury bill, for periods within the contractual life of the option, in effect at the time of the grant.

⁽²⁾

The dividend yield is based on the average of historical stock prices and actual dividends paid.

⁽³⁾

Expected volatility is based on the historical volatility of the Company's stock price, over a period similar to the expected life of the option.

⁽⁴⁾

The expected term of the option is based on the historical employee exercise behavior, the vesting terms of the respective option, and a contractual life of either seven or ten years.

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between the Company's closing stock price on the last trading day of the respective years and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2015. This amount varies based on the fair market value of the Company's stock. The total fair value of options vested was $13.2 million, $4.2 million and $2.8 million in income, net of tax, for the years ended December 31, 2013, 2014 and 2015, respectively.

Cash proceeds, tax benefits and intrinsic value related to total stock options exercised during 2013, 2014 and 2015, were as follows (U.S. dollars in thousands):

The Company recognizes stock-based compensation on a straight-line basis, except for performance based awards for which expense is recognized using a graded-attribution method if the results are materially different than the straight-line method. As of December 31, 2015, there was 22.2 million of unrecognized stock-based compensation expense related to nonvested restricted stock awards. That cost is expected to be recognized over a weighted-average period of 2.5 years. As of December 31, 2015, there was $4.4 million of unrecognized stock-based compensation expense related to nonvested stock option awards. That cost is expected to be recognized over a weighted-average period of 2.6 years.

Notes to Consolidated Financial Statements

The following methods and assumptions were used to determine the fair value of each class of assets and liabilities recorded at fair value in the consolidated balance sheets:

Cash equivalents and current investments: Cash equivalents and current investments primarily consist of highly rated money market funds with maturities of three months or less, and are purchased daily at par value with specified yield rates. Due to the high ratings and short-term nature of the funds, the Company considers all cash equivalents and current investments as Level 1. Current investments include $11.8 million and $14.4 million as of December 31, 2014 and 2015, respectively, that is restricted for the Company's voluntary participation in a consumer protection cooperative in South Korea.

Forward contracts: To hedge foreign currency risks, the Company uses foreign currency exchange forward contracts, where possible and practical. These forward contracts are valued using standard valuation formulas with assumptions about foreign currency exchange rates derived from existing exchange rates as discussed in Note 17 "Derivative Financial Instruments".

Life insurance contracts: ASC 820 preserves practicability exceptions to fair value measurements provided by other applicable GAAP. The guidance in ASC 715-30-35-60 allows a reporting entity, as a practical expedient, to use cash surrender value or conversion value as an expedient for fair value when it is present. Accordingly, the Company determines the fair value of its life insurance contracts as the cash-surrender value of life insurance policies held in its Rabbi Trust as disclosed in Note 16 "Executive Deferred Compensation Plan".

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	2014			2015

Beginning balance at January 1	$	23,172		$	26,280
Actual return on plan assets:

The Company's foreign taxes paid are high relative to foreign operating income and the Company's U.S. taxes paid are low relative to U.S. operating income due largely to the flow of funds among the Company's Subsidiaries around the world. As payments for services, management fees, license arrangements and royalties are made from the Company's foreign affiliates to its U.S. corporate headquarters, these payments often incur withholding and other forms of tax that are generally creditable for U.S. tax purposes. Therefore, these payments lead to increased foreign effective tax rates and lower U.S. effective tax rates. Variations occur in the Company's foreign and U.S. effective tax rates from year to year depending on several factors. These factors include the impact of global transfer prices, the timing and level of remittances from foreign affiliates, profits and losses in various markets, the valuation of deferred tax assets or liabilities, or changes in tax laws, regulations, accounting principles, or interpretations thereof.

Valuation allowance		(35,999	)		(49,271	)
Deferred taxes, net	$	39,951		$	24,196

At December 31, 2015, the Company had foreign operating loss carryforwards of $34.7 million for tax purposes, which will be available to offset future taxable income. If not used, $15.0 million of carryforwards will expire between 2016 and 2025, while $19.7 million do not expire. A valuation allowance has been placed on foreign operating loss carryforwards of $28.4 million.

The valuation allowance primarily represents amounts for foreign operating loss carryforwards and unrealized foreign exchange losses for which it is more likely than not some portion or all of the deferred tax asset will not be realized. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary difference, projected future taxable income, tax planning strategies and recent financial operations. When the Company determines that there is sufficient taxable income to utilize the net operating losses, the valuation will be released which would reduce the provision for income taxes.

Decreases in valuation allowance due to lapse in statute of limitation of the net operating losses carryforward which had no impact to the income statement.

⁽²⁾

Represents the net currency effects of translating valuation allowances at current rates of exchange.

⁽³⁾

The increase was due primarily to the deferred tax assets created by the unrealized loss in Venezuela for which the Company set up a full valuation allowance.

The components of deferred taxes, net on a jurisdiction basis are as follows (U.S. dollars in thousands):

	Year Ended December 31,
	2014		2015
Net current deferred tax assets	$	40,840	$	─
Net noncurrent deferred tax assets		15,128		40,373
Total net deferred tax assets		55,968		40,373

Net current deferred tax liabilities	─		─
Net noncurrent deferred tax liabilities		16,017		16,177
Total net deferred tax liabilities		16,017		16,177
Deferred taxes, net	$	39,951	$	24,196

Effective December 31, 2015, the Company elected to early adopt ASU 2015-17, which requires entities to classify deferred tax liabilities and assets as noncurrent. This guidance has been applied prospectively for the year ended December 31, 2015. The Company has not adjusted the balances for the year ended December 31, 2014.

The Company is subject to regular audits by federal, state and foreign tax authorities. These audits may result in proposed assessments that may result in additional tax liabilities.

The actual tax rate for the years ended December 31, 2013, 2014 and 2015 compared to the statutory U.S. Federal tax rate is as follows:

	Year Ended December 31,
	2013			2014			2015

Income taxes at statutory rate		35.00	%		35.00	%		35.00	%
Foreign tax rate differential		(0.76	)	─				.92
Non-deductible expenses		0.12			0.12			0.09
Controlled foreign corporation losses	─				1.48			1.09
Other		0.12			0.03			0.13
		34.48	%		36.63	%		37.23	%

The lower effective tax rate in 2013 compared to 2014 and 2015 was primarily attributable to indefinitely invested earnings of non-U.S. Subsidiaries. The effective tax rate in 2014 was also impacted by the foreign currency charge relating to Venezuela, for which a valuation allowance was recognized, offset by the re-measurement of Venezuela's books due to the highly inflationary accounting treatment under U.S. GAAP. The year-over-year increase in the effective tax rate for 2015 was due largely to the lower than anticipated profits in China caused by the charge to inventory. Consequently, a deferred tax asset associated with China could not be recognized, thereby impacting the annual effective tax rate.

The cumulative amount of undistributed earnings of the Company's non-U.S. Subsidiaries held for indefinite reinvestment is approximately $50.0 million, $50.0 million and $70.0 million at December 31, 2013, 2014 and 2015, respectively. If this amount were repatriated to the United States, the amount of incremental taxes would be approximately $3.4 million.

All benefits under the deferred compensation plan are unsecured obligations of the Company. The Company has contributed assets to a "rabbi trust" for the payment of benefits under the deferred compensation plan. As the assets of the trust are available to satisfy the claims of general creditors if the Company becomes insolvent, the amounts held in the trust are accounted for as an investment on the Company's consolidated balance sheet of $26.3 million and $27.3 million for the years ended December 31, 2014 and 2015, respectively.

Commitments and Contingencies	12 Months Ended
Commitments and Contingencies	Dec. 31, 2015
Commitments and Contingencies [Abstract]
Commitments and Contingencies	20. 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. 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. NU SKIN ENTERPRISES, INC. Notes to Consolidated Financial Statements The Company is currently involved in a dispute related to customs assessments by Yokohama Customs on several of the Company's products 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 Company was previously required to post a bond or make a deposit to secure any additional duties that may have been due and payable on current imports, but it is no longer required to do so). Additional assessments related to any prior period are barred by applicable statutes of limitations. The aggregate amount of these assessments and disputed duties was approximately 4.3 billion Japanese yen as of December 31, 2015 (approximately $35.4 million), net of recovery of consumption taxes. 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 pursuant to the transaction value method under the World Trade Organization Customs Valuation Agreement or whether it must use one of the alternative valuation methods provided in that agreement, 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 use of the manufacturer's invoice is the appropriate valuation method and that the additional assessments are improper and are not supported by applicable customs laws because they are based on an alternative valuation method. 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. The Company filed letters of protest with the applicable Customs authorities, which were rejected. The Company then appealed the matter to the Ministry of Finance in Japan. In the second quarter of 2011, 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 is not required to give deference to the decision made by the Ministry of Finance and which the Company believes will provide a more independent determination of the matter. In June 2015, the Tokyo District Court closed the proceedings, and we currently anticipate a decision on the matter during the first quarter of 2016. If the Company is unsuccessful in recovering the amounts assessed and paid, the Company will record a non-cash expense in Cost of sales for the full amount of the disputed assessments. The Company anticipates that additional disputed duties will be limited going forward as the Company purchases a majority of the affected products in Japan from a Japanese company that purchases and imports the products from the manufacturers. The Company is also currently being sued in a purported class action lawsuit and derivative claim relating to negative media and regulatory scrutiny regarding the Company's business in Mainland China and the associated decline in the Company's stock price. Beginning in January 2014, six purported class action complaints were filed in the United States District Court for the District of Utah. On May 1, 2014, the court consolidated the various purported class actions, appointed State-Boston Retirement System as lead plaintiff in the consolidated action and appointed the law firm Labaton Sucharow as lead counsel for the purported class in the consolidated action. In June 2014, a consolidated class action complaint was filed. In February 2015, the court denied the Company's motion to dismiss the case. The consolidated class action complaint purports to assert claims on behalf of certain of the Company's stockholders under Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder against Nu Skin Enterprises, Ritch N. Wood, and M. Truman Hunt and to assert claims under Section 20(a) of the Securities Exchange Act of 1934 against Messrs. Wood and Hunt. The consolidated class action complaint alleges that, inter alia, the Company made materially false and misleading statements regarding its sales operations in and financial results derived from Mainland China, including purportedly operating a pyramid scheme based on illegal multi-level marketing activities. The parties are engaging in a mediation process in an effort to resolve this matter. The Company believes the claims are without merit, but has entered into this process in an effort to avoid potentially lengthy, costly, distracting and time-consuming litigation. NU SKIN ENTERPRISES, INC. Notes to Consolidated Financial Statements In addition, beginning in February 2014, five purported shareholder derivative complaints were filed in the United States District Court for the District of Utah. In May 2014, the court issued an order consolidating the derivative actions, appointing plaintiffs Amos. C. Acoff and Analisa Suderov as co-lead plaintiffs in the consolidated action, and appointing the law firms Bernstein Litowitz Berger & Grossmann LLP and The Weiser Law Firm, P.C. as co-lead counsel for the plaintiffs in the consolidated action. In July 2014, a consolidated derivative complaint was filed. In July 2015, the court stayed the derivative action pending a resolution in the securities class action lawsuit and denied the Company's motion to dismiss without prejudice to renewing the motion when the stay is lifted. The consolidated derivative complaint purports to assert claims on behalf of Nu Skin Enterprises, Inc. for, inter alia, breach of fiduciary duties for disseminating false and misleading information, failing to maintain adequate internal controls, unjust enrichment, abuse of control, and gross mismanagement against M. Truman Hunt, Ritch N. Wood, Steven J. Lund, Nevin N. Andersen, Neil H. Offen, Daniel W. Campbell, Andrew W. Lipman, Patricia A. Negrón, Thomas R. Pisano, and nominally against Nu Skin Enterprises, Inc. The consolidated derivative complaint also purports to assert claims on behalf of Nu Skin Enterprises, Inc. for breach of fiduciary duty for insider selling and misappropriation of information against Messrs. Wood, Lund and Campbell. The consolidated derivative complaint alleges that, inter alia, the defendants allowed materially false and misleading statements to be made regarding their sales operations in and financial results derived from Mainland China, including purportedly operating a pyramid scheme based on illegal multi-level marketing activities, and that certain defendants sold common stock on the basis of material, adverse non-public information. The purported class action lawsuit and derivative claim, or others filed alleging similar facts, could result in monetary or other penalties that may materially affect the Company's operating results and financial condition. At this stage of the proceedings, the Company is unable to make an estimate of the potential loss, if any, arising from these matters.

Stock Option Valuation Assumptions

The fair value of stock option awards was estimated using the Black-Scholes option-pricing model with the following assumptions and weighted-average fair values as follows:

	December 31,
Stock Options:	2013		2014		2015

Weighted average grant date fair value of grants	$	22.10	$	23.01	$	16.26
Risk-free interest rate⁽¹⁾		1.4%		1.7%		1.7%
Dividend yield⁽²⁾		3.1%		1.9%		2.1%
Expected volatility⁽³⁾		41.7%		45.4%		46.8%
Expected life in months⁽⁴⁾	62 months		62 months		65 months

⁽¹⁾

The risk-free interest rate is based upon the rate on a zero coupon U.S. Treasury bill, for periods within the contractual life of the option, in effect at the time of the grant.

⁽²⁾

The dividend yield is based on the average of historical stock prices and actual dividends paid.

⁽³⁾

Expected volatility is based on the historical volatility of the Company's stock price, over a period similar to the expected life of the option.

⁽⁴⁾

The expected term of the option is based on the historical employee exercise behavior, the vesting terms of the respective option, and a contractual life of either seven or ten years.
