Capital Stock

12 Months Ended

Dec. 31, 2023

Capital Stock [Abstract]

Capital Stock

8.	Capital Stock

The Company’s authorized capital stock consists of 25 million shares of preferred stock, par value $0.001 per share, 500 million shares of Class A common stock, par value $0.001 per share, and 100 million shares of Class B common stock, par value $0.001 per share. As of December 31, 2023 and 2022, there were no preferred or Class B common shares outstanding. Each share of Class A common stock entitles the holder to one vote on matters submitted to a vote of the Company’s stockholders. Stock dividends of Class A common stock may be paid only to holders of Class A common stock. Class A common stock has no conversion rights.

Weighted-average common shares outstanding

The following is a reconciliation of the weighted-average common shares outstanding for purposes of computing basic and diluted net income per share (in thousands):

	Year Ended December 31,
	2023		2022		2021
Basic weighted-average common shares outstanding		49,711		50,002		50,193
Effect of dilutive securities:
Stock awards and options		149		523		1,234
Diluted weighted-average common shares outstanding		49,860		50,525		51,427

For the years ended December 31, 2023, 2022 and 2021, other stock options totaling 1.8 million, 0.1 million and 0.1 million, respectively, were excluded from the calculation of diluted earnings per share because they were anti-dilutive.

Dividends

Quarterly cash dividends for the years ended December 31, 2023 and 2022 totaled $77.6 million and $77.0 million or $0.39 per share in all quarters of 2023 and $0.385 for all quarters of 2022. In February 2024, the board of directors has declared a quarterly cash dividend of $0.06 per share of Class A common stock to be paid on March 6, 2024 to stockholders of record on February 26, 2024.

Repurchases of common stock

In July 2018, the Company’s board of directors approved a stock repurchase plan with an authorization amount of $500 million. The repurchases are used primarily for strategic initiatives and to offset dilution from the Company’s equity incentive plans. During the years ended December 31, 2023, 2022 and 2021, the Company purchased 0.6 million, 1.7 million and 1.6 million shares under the 2018 plan for $13.0 million, $70.0 million and $80.4 million, respectively. At December 31, 2023, $162.4 million was available for repurchases under the 2018 stock repurchase plan.

- Definition

The entire disclosure for equity.

Stock-Based Compensation [Abstract]

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:

Stock Options:	December 31, 2021
Weighted-average grant date fair value of grants	$	16.10
Risk-free interest rate⁽¹⁾		0.5	%
Dividend yield⁽²⁾		2.9	%
Expected volatility⁽³⁾		49.5	%
Expected life in months⁽⁴⁾	56 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.

Stock-Based Compensation

9.	Stock–Based Compensation

At December 31, 2023, 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. On May 24, 2016, the Company’s stockholders approved a Second Amended and Restated 2010 Omnibus Incentive Plan, which among other things increased the number of shares available for awards by 3.8 million shares. On June 3, 2020, the Company’s stockholders approved a Third Amended and Restated 2010 Omnibus Incentive Plan, which among other things increased the number of shares available for awards by 5.9 million shares.

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:

Stock Options:	December 31, 2021
Weighted-average grant date fair value of grants	$	16.10
Risk-free interest rate⁽¹⁾		0.5	%

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, 2023. This amount varies based on the fair market value of the Company’s stock.

Cash proceeds, tax benefits and intrinsic value related to total stock options exercised during 2023, 2022 and 2021, were as follows (U.S. dollars in thousands):

Stock-based compensation expense is recognized 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. The Company recognized no expense related to service condition stock options in 2023, 2022 and 2021; and recognized $14.4 million, $14.3 million and $15.4 million of expense related to service condition restricted stock units in 2023, 2022 and 2021, respectively. For performance stock options and performance stock units, an expense is recorded each period for the estimated expense associated with the projected achievement of the performance-based targets. The Company recognized none, $2.0 million of income and $7.8 million of expense related to performance stock options in 2023, 2022 and 2021, respectively; and $1.2 million expense, none and none related to performance stock units in 2023, 2022 and 2021, respectively. The amount in 2022 reflects the reversal of stock compensation for awards no longer expected to vest.

As of December 31, 2023, there was no unrecognized stock-based compensation expense related to nonvested stock option awards. As of December 31, 2023, there was $26.8 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.

Commitments and Contingencies

16.	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. The Company is subject to loss contingencies, including various legal and regulatory proceedings, asserted and potential claims that arise in the ordinary course of business. An estimated loss from such contingencies is recognized as a charge to income if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

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.

Credit Agreement

On June 14, 2022, the Company entered into an Amended and Restated Credit Agreement (the “Credit Agreement”) with several financial institutions as lenders and Bank of America, N.A., as administrative agent, which amended and restated the 2018 Credit Agreement. The Credit Agreement provides for a $400 million term loan facility and a $500 million revolving credit facility, each with a term of five years. Both facilities bear interest at the SOFR, plus a margin based on the Company’s consolidated leverage ratio. Commitment fees payable under the Credit Agreement are also based on the consolidated leverage ratio as defined in the Credit Agreement and range from 0.175% to 0.30% on the unused portion of the total lender commitments then in effect. The term loan facility amortizes in quarterly installments in amounts resulting in an annual amortization of 2.5% during the first year and 5.0% during the second, third, fourth and fifth years after the closing date of the Credit Agreement, with the remainder payable at final maturity. The Credit Agreement is guaranteed by certain of the Company’s domestic subsidiaries and collateralized by assets of such subsidiaries, including a pledge of 65% of the capital stock of certain foreign subsidiaries. The Credit Agreement requires the Company to maintain a consolidated leverage ratio not exceeding 2.75 to 1.00 and a consolidated interest coverage ratio of no less than 3.00 to 1.00. As of December 31, 2023, the Company was in compliance with all covenants under the Credit Agreement.

The following table summarizes the Company’s debt facilities as of December 31, 2023 and 2022:

Facility or Arrangement	Original Principal Amount	Balance as of December 31, 2023 ⁽¹⁾⁽²⁾	Balance as of December 31, 2022 ⁽¹⁾⁽²⁾	Interest Rate	Repayment Terms

Segment Information [Abstract]

Segment Information

15.	Segment Information

The Company reports revenue from nine segments, consisting of its seven geographic Nu Skin segments—Americas, Mainland China, Southeast Asia/Pacific, South Korea, Japan, Europe & Africa, and Hong Kong/Taiwan—and two Rhyz segments—Manufacturing and Rhyz other. The Nu Skin other category includes miscellaneous corporate revenue and related adjustments. The Rhyz other segment includes other investments by our Rhyz business arm. These segments reflect the way the chief operating decision maker evaluates the Company’s business performance and allocates resources. Reported revenue includes only the revenue generated by sales to external customers.

Profitability by segment as determined under US GAAP is driven primarily by the Company’s transfer pricing 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, and marketing and supply chain functions not recorded at the segment level.

In the first quarter of 2023, the Company adjusted how it allocates certain corporate overhead costs to the segments. The prior-year segment information has been recast to comply with current presentation. Consolidated financial information is not affected.

Effective June 2023, the Company closed its Israel market. As a result the Europe, Middle East and Africa (“EMEA”) segment has been renamed Europe & Africa.

The accounting policies of the segments are the same as those described in Note 2, “Summary of Significant Accounting Policies.” 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.

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 $4.0 million and $4.9 million as of December 31, 2023 and 2022, respectively, that is restricted for the Company’s voluntary participation in a consumer protection cooperative in South Korea, along with investments in corporate securities.

Life insurance contracts: ASC 820 preserves practicability exceptions to fair value measurements provided by other applicable provisions of U.S. 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 13, “Deferred Compensation Plan.”

Derivative financial instruments asset and liability: Derivative financial instruments are measured at fair value based on observable market information and appropriate valuation methods. See Note 14, “Derivative Financial Instruments” for more information on derivative financial instruments.

Contingent consideration: Contingent consideration represents the obligations incurred in connection with acquisitions. The estimate of fair value of the contingent consideration obligations requires subjective assumptions to be made regarding the future business results, discount rates, discount periods and probabilities assigned to various potential business result scenarios and was determined using probability assessments with respect to the likelihood of reaching various targets or of achieving certain milestones. The fair value measurement is based on significant inputs unobservable in the market and thus represents a level 3 measurement. Changes in current expectations of progress could change the probability of achieving the targets within the measurement periods and result in an increase or decrease in the fair value of the contingent consideration obligation.

The following table provides a summary of changes in fair value of the Company’s Level 3 life insurance contracts (U.S. dollars in thousands):

	2023			2022
Beginning balance at January 1	$	40,055		$	49,851
Actual return on plan assets		6,216			(9,180	)
Sales and settlements		(1,230	)		(616	)
Ending balance at December 31	$	45,041		$	40,055

Changes in fair value of contingent consideration		64			3,977
Ending balance at December 31	$	(6,300	)	$	(6,364	)

Equity Investments

The Company maintains equity investments in companies which are accounted for under the measurement alternative described in ASC 321-10-35-2 for equity securities that lack readily determinable fair values. The carrying amount of equity securities held by the Company without readily determinable fair values was $28.1 million as of December 31, 2023 and 2022. During the year ended December 31, 2021, the Company recognized $18.1 million of upward fair value adjustments, based on the third quarter of 2021 valuation of additional equity issued by the investee which was deemed to be an observable transaction of a similar investment under ASC 321. The gain was recorded within Other expense, net on the consolidated statement of income. The upward fair value adjustment represents a nonrecurring fair value measurement based on observable price changes and is classified as a level 2 fair value measurement.

Derivative Financial Instruments

14.	Derivative Financial Instruments

Risk Management Objective of Using Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s borrowings.

Cash Flow Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. During 2023, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt.

For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in Accumulated Other Comprehensive Income and subsequently reclassified into interest expense/income in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense/income as interest payments are made/received on the Company’s variable-rate debt. During the next twelve months, the Company estimates that an additional $9.0 million will be reclassified as a reduction to interest expense.

As of December 31, 2023, the Company had four outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk with a total notional amount of $200 million.

Deferred Compensation Plan [Abstract]

Deferred Compensation Plan

13.	Deferred Compensation Plan

The Company has a deferred compensation plan for select management personnel, highly compensated employees, and members of the Company’s board of directors. Under this plan, the Company may make discretionary contributions to participants’ deferred compensation accounts; prior to 2021, the Company historically contributed 10% of base salary for participants above a specified job level. In addition, each participant has the option to defer a portion of their compensation up to a maximum of 80% of their base salary and 100% of their bonuses or director fees. Participant contributions are immediately vested. Company contributions made on or prior to December 31, 2020 will vest 50% after ten years of service and 5% each year of service thereafter. In addition, any unvested company contributions will fully vest on the earlier of: (a) the participant attaining 60 years of age; and (b) death or disability.

Effective January 1, 2021, the Company amended its deferred compensation plan. Under the revision, the Company shall make matching contributions up to 5% of base salary for participants above a specified job level. The revision continues to authorize the Company to make discretionary contributions to participants’ deferred compensation accounts. In view of the opportunity to receive a 5% match, the Company reduced its discretionary contributions to 5% of base salary each year, though the Company is not obligated to make these contributions. Under the amendment, the amounts contributed by the Company, adjusted for earnings and losses thereon, will vest 20% per year over five years, subject to acceleration upon the occurrence of certain events, including the completion of at least ten years of employment above a specified job level. All amounts a participant elects to defer, adjusted for earnings and losses thereon, are 100% vested at all times.

The Company recorded compensation expense of $2.8 million, $2.3 million and $4.0 million for the years ended December 31, 2023, 2022 and 2021, respectively, related to its contributions to the plan. The total long-term deferred compensation liability under the deferred compensation plan was $49.2 million and $44.4 million for the years ended December 31, 2023 and 2022, respectively, related to its contributions to the plan and is included in other long-term liabilities.

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 sheets of $45.0 million and $40.1 million for the years ended December 31, 2023 and 2022, respectively.

Summary of Significant Accounting Policies [Abstract]

Consolidation

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

Use of Estimates

Use of estimates

The preparation of these financial statements, in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), 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 and cash equivalents

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

Accounts Receivable

Accounts receivable

Accounts receivable represents amounts owed to us through our operating activities and are presented net of allowance for doubtful accounts. Accounts receivable for core Nu Skin consists primarily of credit card receivables, while accounts receivable for our Rhyz businesses consists primarily of trade receivables from customer sales. For the Company’s trade receivables from its Rhyz customers, the Company performs ongoing credit evaluations of its customers and maintains an allowance for expected credit losses. The allowance for expected credit losses represents the Company’s best estimate based on current and historical information, and reasonable and supportable forecasts of future events and circumstances.

Inventories

Inventories consist primarily of merchandise purchased for resale and are stated at the lower of standard cost or net realizable value, using a standard cost method which approximates the first-in, first-out method. The Company had reserves of its inventory carrying value totaling $83.4 million and $37.3 million as of December 31, 2023 and 2022, respectively.

Inventories consist of the following (U.S. dollars in thousands):

	December 31,
	2023		2022
Raw materials	$	140,133	$	163,797
Finished goods		139,845		182,386
Total inventory, net	$	279,978	$	346,183

Reserves of inventories consist of the following (U.S. dollars in thousands):

	2023			2022			2021
Beginning balance	$	37,267		$	18,643		$	14,249

Disposals		(41,997	)		(24,662	)		(26,906	)
Ending balance	$	83,378		$	37,267		$	18,643

Property and Equipment

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.

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, accrued expenses and operating lease liabilities on the consolidated balance sheets. Finance leases are included in other assets, accrued expenses and other liabilities on the consolidated balance sheets.

Operating lease ROU assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The Company uses its estimated incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU assets also include any lease payments made and exclude lease incentives and initial direct costs incurred. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Leases with a term of 12 months or less are not recorded on the balance sheet. The Company’s lease agreements do not contain any residual value guarantees.

The Company has lease agreements with lease and non-lease components. The Company accounts for the lease and non-lease components as a single lease component.

Goodwill and Other Intangible Assets

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 October 1. 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 (“ASC 350”), 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 elected to perform the qualitative assessment during fiscal year 2023 and 2021, and determined that it is not more likely than not the carrying value exceeds the fair value of the reporting units. In fiscal years 2022, a quantitative assessment was performed. 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.

As discussed further in Note 20 of the Notes to Consolidated Financial Statements, during the fourth quarter of fiscal year 2021, the Company recognized an $18.2 million goodwill and intangibles impairment charge related to the Grow Tech segment, which was included in Restructuring and impairment expenses in the consolidated statement of income. During fiscal year 2022, the Company recorded a $1.7 million impairment of other intangibles.

The Company completed the annual goodwill and indefinite-lived intangible asset impairment testing as of October 1, 2023, and concluded the qualitative assessment indicated that the fair value of the Company’s reporting units exceeded their carrying value and therefore were not at risk for impairment. If there is continued deterioration of economic conditions it may lead to an impairment. As of the October 1, 2022 quantitative analysis testing date, the fair value of the Manufacturing reporting unit was estimated to be approximately 8% in excess of its carrying amount, and therefore the reporting unit is considered to be at risk of future impairment. The Manufacturing reporting unit’s fair value remains sensitive to significant unfavorable changes in revenue, gross margin and discount rates that could negatively impact future analyses.

Equity Investments

Equity investments

The Company holds strategic investments in other companies. These investments are accounted for under the measurement alternative described in ASC 321, Investments - Equity Securities (“ASC 321”) for equity investments that do not have readily determinable fair values. These investments are measured at cost, less impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer. The Company does not exercise significant influence over these companies. These investments are carried on the consolidated balance sheets within Other Assets. Changes in fair value based on impairments or resulting from observable price changes are recorded in Other Income (expense), net on the consolidated statements of income. See Note 10 – Fair Value and Equity Investments, for further details around the Company’s equity investments.

Revenue Recognition

Revenue recognition

Net sales include products and shipping and handling charges, net of estimates for product returns and any related sales incentives. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products. All revenue is recognized when we satisfy our performance obligations under the contract. The Company recognizes revenue by transferring the promised products to the customer, with revenue recognized at shipping point, the point in time the customer obtains control of the products. The Company recognizes revenue for shipping and handling charges at the time the products are delivered to or picked up by the customer. A reserve for product returns is accrued based on historical experience totaling $4.7 million and $3.4 million as of December 31, 2023 and 2022, respectively. During the years ended December 31, 2023, 2022 and 2021, the Company recorded sales returns of $34.7 million, $31.6 million and $52.1 million, respectively. The majority of the Company’s contracts have a single performance obligation and are short term in nature. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales.

Contract Liabilities – Customer Loyalty Programs

Contract liabilities, recorded as deferred revenue within the accrued expenses line in the consolidated balance sheets, include loyalty point program deferrals with certain customers which are accounted for as a reduction in the transaction price and are generally recognized as points are redeemed for additional products.

The balance of deferred revenue related to contract liabilities was $12.6 million and $18.7 million as of December 31, 2023, and 2022, respectively. The contract liabilities impact to revenue for the years ended December 31, 2023, 2022 and 2021 was an increase of $6.1 million, an increase of $3.3 million and a decrease of $3.8 million, respectively.

Disaggregation of Revenue

Please refer to Note 15 - Segment Information for revenue by segment and product line.

Arrangements with Multiple Performance Obligations

The Company’s contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenues to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices charged to customers for individual products sales to customers.

Shipping and Handling Costs

Shipping and handling costs

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

Advertising Expenses

Advertising expenses

Advertising costs are expensed as incurred and are included in general and administrative expenses in the accompanying consolidated statements of income. Advertising expense incurred for the years ended December 31, 2023, 2022 and 2021 totaled $18.0 million, $14.5 million and $15.5 million, respectively.

Selling Expenses

Selling expenses

Selling expenses are the Company’s most significant expense and are classified as operating expenses. Selling expenses include commissions the Company pays to its Brand Affiliates, as well as salaries, service fees, benefits, bonuses and other labor and unemployment expenses the Company pays to its sales force in Mainland China. Selling expenses do not include amounts the Company pays to its sales force based on their personal purchases; rather, such amounts are reflected as reductions to revenue. The term “Brand Affiliates” refers to members of the Company’s independent sales force in all of the Company’s markets besides 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.

Outside of Mainland China, the Company’s Brand Affiliates 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 Brand Affiliates. 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

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 $22.6 million, $23.3 million and $27.2 million in 2023, 2022 and 2021, respectively.

Deferred Tax Assets and Liabilities

Deferred tax assets and liabilities

The Company accounts for income taxes in accordance with ASC 740 “Income Taxes.” 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. These deferred tax assets assume sufficient future earnings will exist for their realization, and are calculated using anticipated tax rates. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be ultimately realized.

Uncertain Tax Positions

Uncertain tax positions

The Company files income tax returns in the U.S. federal jurisdiction, and in various state and foreign jurisdictions. In 2009, we entered into a voluntary program with the IRS called Compliance Assurance Process (“CAP”). Under the CAP program, the IRS audits the tax position of the Company to identify and resolve any tax issues that may arise throughout the tax year. The IRS has developed a new pilot phase called “Bridge Plus.” Under Bridge Plus the taxpayer is required to provide book-to-tax reconciliations, credit utilization and other supporting documentation shortly after their audited financial statement is finalized. The company was selected for Bridge Plus for the 2022, 2023, and 2024 tax years. As of December 31, 2023, all open tax years except 2021 have been audited and are effectively closed to further examination. For the tax year 2021, the Company was in the Bridge phase of the CAP program, pursuant to which the IRS did not accept disclosures, did not conduct reviews and did not provide letters of assurance for the year. There are limited circumstances that tax years in the Bridge phase will be opened for examination. With a few exceptions, we are no longer subject to state and local income tax examination by tax authorities for the years before 2020. Foreign jurisdictions have varying lengths of statutes of limitations for income tax examinations. Some statutes are as short as three years and in certain markets may be as long as ten years. The Company is currently under examination in certain foreign jurisdictions; however, the outcomes of those reviews are not yet determinable.

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

	2023			2022			2021
Gross balance at January 1	$	23,099		$	15,090		$	17,620
Increases related to prior year tax positions		180			6,768			4,146
Increases related to current year tax positions		3,065			5,485			1,794
Settlements		(2,378	)		(2,590	)		(5,494	)
Decreases due to lapse of statutes of limitations		(1,284	)		(95	)		(2,409	)
Currency adjustments		(680	)		(1,559	)		(567	)
Gross balance at December 31	$	22,002		$	23,099		$	15,090

At December 31, 2023, the Company had $22.0 million in unrecognized tax benefits of which $22.0 million, if recognized, would affect the effective tax rate. In comparison, at December 31, 2022, the Company had $23.1 million in unrecognized tax benefits of which $23.1 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 changes 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 $2.0 to $3.0 million.

During the years ended December 31, 2023, 2022 and 2021 the Company recognized $0.6 million, $5.7 million and $1.6 million, respectively in interest and penalties expenses related to uncertain tax positions. The Company had $13.0 million, $12.4 million and $6.7 million of accrued interest and penalties related to uncertain tax positions at December 31, 2023, 2022 and 2021, 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

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 8).

Foreign Currency Translation and Classification of a Highly Inflationary Economy

Foreign currency translation

A significant portion of the Company’s business operations occurs 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 countries deemed highly inflationary 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 (expense) in the consolidated statements of income. Net of tax, the accumulated other comprehensive loss related to the foreign currency translation adjustments are $110.0 million (net of tax of $7.4 million), $102.0 million (net of tax of $8.1 million), and $79.1 million (net of tax of $7.5 million), at December 31, 2023, 2022 and 2021, respectively.

Classification of a highly inflationary economy

A market 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, and transactions denominated in the local currency are remeasured to the functional currency. The remeasurement of local currency into U.S. dollars creates foreign currency transaction gains or losses, which the Company includes in its consolidated statements of income.

In the second quarter of 2018, published inflation indices indicated that the three-year cumulative inflation in Argentina exceeded 100 percent, and as of July 1, 2018, we elected to adopt highly inflationary accounting for our subsidiary in Argentina. Under highly inflationary accounting, Argentina’s functional currency became the U.S. dollar, and its income statement and balance sheet have been measured in U.S. dollars using both current and historical rates of exchange. The effect of changes in exchange rates on peso-denominated monetary assets and liabilities has been reflected in earnings in Other expense, net and was not material. As of December 31, 2023, and 2022, Argentina had a small net peso monetary position. Net sales of Argentina were less than 1 percent of our consolidated net sales for the years ended December 31, 2023, 2022 and 2021.

Fair Value of Financial Instruments

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, 2023 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, 2023 and 2022, the fair value of debt was $505.0 million and $405.0 million, respectively. The fair value of the Company’s debt is estimated using level 2 inputs based on interest rates available for debt with similar terms and remaining maturities.

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

Stock-based compensation

All share-based payments, including grants of stock options and restricted stock units, are required to be recognized in the Company’s 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 the Company’s stock price and a number of assumptions, including expected volatility, expected life, risk-free interest rate and expected dividends. The Company uses 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 the Company’s stock options. The fair value of the Company’s restricted stock units is based on the closing market price of its stock on the date of grant less the Company’s expected dividend yield. The Company recognizes stock-based compensation net of actual forfeitures over the requisite service period of the award.

The total compensation expense related to equity compensation plans was $15.6 million, $12.4 million and $23.2 million for the years ended December 31, 2023, 2022 and 2021, respectively. In 2023, 2022 and 2021, these amounts reflect the reversal of $0, $1.3, and $0, respectively, for certain performance-based awards that were no longer expected to vest. For the years ended December 31, 2023, 2022 and 2021, all stock-based compensation expense was recorded within general and administrative expenses.

Reporting Comprehensive Income

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.

Derivative Instruments and Hedging Activities

Derivative instruments and hedging activities

FASB ASC 815, Derivatives and Hedging (“ASC 815”), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments.

As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

In accordance with the FASB’s fair value measurement guidance in ASU 2011-04, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.

Recent Accounting Pronouncements

Recent accounting pronouncements

In November 2023, the FASB issued ASU 2023-07,Segment Reporting (Topic 280):Improvements to Reportable Segment Disclosures, expanding segment disclosure requirements. The amendments require enhanced disclosure for certain segment items and required disclosure on how management uses reported measures to assess segment performance. The amendments do not change how segments are determined, aggregated, or how thresholds are applied to determine reportable segments. ASU 2023-07 is effective for the Company’s annual periods beginning January 1, 2024, and for interim periods beginning January 1, 2025, with early adoption permitted. The Company is currently evaluating the potential effect that the updated standard will have on their financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The guidance requires disclosure of disaggregated income taxes paid, prescribes standardized categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. ASU 2023-09 is effective for the Company’s annual periods beginning January 1, 2025, with early adoption permitted. The Company is currently evaluating the potential effect that the updated standard will have on their financial statement disclosures.

Restructuring and Severance Charges

20.	Restructuring and Severance Charges

In 2021, the Company determined to exit the Grow Tech segment to better align its resources on key strategic initiatives to achieve the future growth objectives and priorities of the core Nu Skin business. The Grow Tech segment was pursuing the commercialization of controlled-environment agriculture for use in the agriculture feed industry. This segment operated as part of the Company’s Rhyz strategic investment arm. As a result of the restructuring program, the Company recorded a non-cash charge of $38.5 million in 2021, including $9.2 million for impairment of goodwill, $9.0 million for impairment of intangibles, $13.7 million of fixed asset impairments and $6.6 million for inventory write-off, and $20.0 million of cash charges, including $6.5 million for employee severance and $13.5 million for other related cash charges with our restructuring. The restructuring charges were recorded in the Grow Tech segment. During 2022, the Company incurred $5.0 million in incremental cash charges associated with the exit activities and legal settlements. During 2022, the Company made cash payments of $20.0 million, leaving a restructuring accrual of $5.0 million as of December 31, 2022. The Company paid this amount during 2023, leaving no restructuring accrual related to our exit of the Grow Tech segment as of December 31, 2023.

In the third quarter of 2022, the Company adopted a strategic plan (“2022 Plan”) to focus resources on the Company’s strategic priorities and optimize future growth and profitability. The global program includes workforce reductions and footprint optimization. The Company incurred total charges under the program of approximately $53.3 million, with $40.8 million in cash charges of severance and lease termination cost and approximately $12.5 million of non-cash charges of impairment of fixed assets, acceleration of depreciation and impairment of other intangibles related to the footprint optimization. During 2022, the Company incurred charges to be settled in cash of $20.1 million in severance charges, $7.4 million in lease termination cost, and $5.2 million in other associated cost, and non-cash charges of $8.2 million in fixed asset impairments, $0.9 million in accelerated depreciation and $1.7 million in impairment of other intangibles. During 2022, the Company made cash payments of $21.0 million related to this global program, leaving an ending restructuring accrual of $11.7 million. During 2023, the Company incurred charges to be settled in cash of $4.0 million in severance charges, $1.9 million in lease termination cost, and $2.2 million in other associated cost, and non-cash charges of $1.7 million in accelerated depreciation. In 2023, the Company made cash payments of $19.8 million, leaving no restructuring accrual related to this plan as of December 31, 2023.

Acquisitions

19.	Acquisitions

In April 2023, the Company acquired 60 percent of LifeDNA, Inc. (“LifeDNA”), a DNA assessment company. Consideration paid included $4.0 million of cash, along with the conversion of a previous $3.0 million Simple Agreement for Future Equity (“SAFE”), and a $0.2 million convertible note. The acquisition enables the Company to continue to expand its digital tools. The Company allocated the fair value of $12.0 million to the assets acquired and liabilities assumed at estimated fair values. The estimated fair value of assets acquired included $7.3 million of intangible assets, $1.7 million of cash, $0.1 million of current assets, $0.9 million of accrued liabilities and also resulted in a deferred tax liability of $0.9 million. The excess purchase price over the aggregate fair value of assets acquired less liabilities assumed of $4.7 million was recorded as goodwill. The goodwill recognized is attributable primarily to expected synergies. None of the goodwill is expected to be deductible for income tax purposes. The intangible assets acquired comprised $0.6 million of customer relationships, $1.7 million of technology, $1.0 million of tradenames and $4.1 million of other intangibles. The intangibles were assigned useful lives of 7 years for the technology, tradenames and other intangibles, and 2 years for the customer relationships. All the goodwill was assigned to our Rhyz Other segment. The numbers above are stated net of measurement period adjustments recorded during the fourth quarter of 2023 of $1.1 million to deferred tax liability and goodwill. The allocation of the fair value of assets acquired and liabilities assumed for the acquisition was finalized during the three months ended December 31, 2023.

In June 2023, the Company acquired 100 percent ownership in Beauty Biosciences, LLC (“BeautyBio”), making BeautyBio a wholly owned subsidiary of the Company. The acquisition expands the Company’s product and device offerings within its Rhyz segment. The purchase price for BeautyBio was $75.0 million, net of cash acquired of $1.5 million, all payable in cash. The Company allocated the gross purchase price of $76.5 million to the assets acquired and liabilities assumed at estimated fair values. The estimated fair value of assets acquired included $43.0 million of intangible assets, $1.5 million of cash, $3.5 million of accounts receivable, $10.3 million of inventory, $0.8 million of prepaid and other assets, $1.0 million of fixed assets, $1.2 million of an ROU operating lease asset and corresponding lease liability, $2.5 million of accounts payable and accrued liabilities and also resulted in a deferred tax liability of $0.7 million. The excess purchase price over the aggregate fair value of assets acquired less liabilities assumed of $19.6 million was recorded as goodwill. The goodwill recognized is attributable primarily to expected synergies. None of the goodwill is expected to be deductible for income tax purposes. The intangible assets acquired comprised $18.4 million of customer relationships, $2.3 million of technology, $20.9 million of tradenames and $1.4 million of other intangibles. The intangibles were assigned useful lives of approximately 19 years for the technology and tradenames, approximately 9 years for the customer relationships and 3 years for the other intangibles. All the goodwill was assigned to our Rhyz Other segment. The numbers above are stated net of measurement period adjustments recorded during the fourth quarter of 2023 of $(1.2) million to accounts receivable, $(0.7) million of inventory, $(0.5) million of accrued liabilities, $0.7 million of deferred tax liability, $(0.3) of intangible assets and $2.4 million of goodwill. As of December 31, 2023, the allocation of the purchase price for the acquisition of BeautyBio is not yet finalized and is subject to adjustments as the Company completes the valuation analysis for this acquisition.

The financial results of LifeDNA and BeautyBio are included in the Rhyz other segment from the date of acquisition. For the year ended December 31, 2023, the Company included $10.6 million of revenue from these acquisitions. The unaudited pro forma revenue for the Company, including LifeDNA and BeautyBio, as if the acquisitions occurred on January 1, 2021, would have been $1,978.8 million and $2,254.2 million and $2,719.8 million for the years ended December 31, 2023, 2022 and 2021, respectively.

At December 31, 2023, the Company had foreign operating loss carryforwards of $46.7 million for tax purposes, which will be available to offset future taxable income. If not used, $34.9 million of carryforwards will expire between 2024 and 2033, while $11.8 million do not expire. Tax effected, the foreign operating losses are $19.7 million. A valuation allowance has been placed on foreign operating loss carryforwards of $19.7 million. In addition, a valuation allowance of $25.1 million has been recorded on a portion of the foreign tax credit carryforwards which will expire between 2028 and 2031, and all of the R&D credit carryforward of $2.3 million which will expire between 2036 and 2042.

The Company uses the tax law ordering approach when determining when excess tax benefits have been realized.

Valuation allowances have been recognized for a portion of the foreign tax credit, the foreign net operating loss carryforwards, and the R&D credit carryforward. During 2023, the Company incurred restructuring charges that primarily affected their U.S. earnings. These additional expenses in the U.S. reduced the Company’s ability to utilize foreign tax credits. As a result, the Company recorded an additional $6.1 million valuation allowance against the Company’s foreign tax credits. The remaining valuation allowances were recognized for assets 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 positive evidence to utilize the remaining foreign tax credits, the foreign net operating losses, or the R&D credit carryforward, the valuation allowance will be released which would reduce the provision for income taxes.

The deferred tax asset valuation adjustments for the years ended December 31, 2023, 2022 and 2021 are as follows (U.S. dollars in thousands):

	Year Ended December 31,
	2023			2022			2021
Balance at the beginning of period	$	33,557		$	80,186		$	67,340
Additions charged to cost and expenses		13,183	⁽¹⁾		3,231	⁽⁴⁾		12,674	⁽⁶⁾
Decreases		(1,825	)⁽²⁾		(50,315	)⁽⁵⁾		—	⁽⁷⁾
Adjustments		2,227	⁽³⁾		455	⁽³⁾		172	⁽³⁾
Balance at the end of the period	$	47,142		$	33,557		$	80,186

(1)	Increase in valuation is due primarily to net operating losses in foreign markets and the $6.1 million that was recorded on the foreign tax credit carryforward.

(2)	The decrease was due to expiration of foreign net operating losses.

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

(4)	Increase in valuation is primarily due to net operating losses in foreign markets.

(5)	The decrease was due to utilization of $18.1 million of foreign tax credits and the valuation allowance release of $32.2 million foreign tax credits.

(6)	Increase in valuation is primarily due to $11.9 million that was recorded on the foreign tax credit carryforward due to the disposal of the Company’s Grow Tech segment. The additional amount is due to net operating losses in foreign markets.

(7)	No decreases in 2021.

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

	Year Ended December 31,
	2023		2022
Net noncurrent deferred tax assets	$	105,529	$	89,770
Net noncurrent deferred tax liabilities		522		439
Deferred taxes, net	$	105,007	$	89,331

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, 2023, 2022 and 2021 compared to the statutory U.S. Federal tax rate is as follows:

	Year Ended December 31,
	2023			2022			2021
Income taxes at statutory rate		21.00	%		21.00	%		21.00	%
Excess tax benefit from equity award		5.04	%		(0.12	)%		(0.19	)%
Deferred compensation		(4.28	)%		2.18	%		(0.46	)%
Executive salary limitation		1.59	%		2.06	%		0.47	%
State taxes		7.34	%		0.25	%		0.50	%
Foreign exchange		(1.91	)%		0.68	%		(0.07	)%
Non-U.S. income taxed at different rates		12.70	%		4.78	%		6.06	%
Foreign withholding taxes		13.31	%		(0.73	)%		4.71	%
Change in reserve for uncertain tax positions		1.74	%		17.69	%		(0.06	)%
Valuation allowance recognized foreign tax credit & others		24.66	%		(56.17	)%		5.12	%
Foreign-Derived Intangible Income (FDII)		(14.11	)%		(8.14	)%		(0.87	)%
Other		0.58	%		(1.25	)%		0.44	%
		67.66	%		(17.77	)%		36.65	%

The increase in the Company’s effective tax rate for 2023 was primarily due to the Company incurring restructuring charges that primarily affected their U.S. earnings. These additional expenses in the U.S. reduced the Company’s ability to utilize foreign tax credits. The decrease in the effective tax rate for 2022 was primarily due to the Company making an election to change its capitalization policy for tax purposes related to certain direct and indirect costs for inventory and self-constructed assets under Internal Revenue Code (“IRC”) Section 263A. This method change allows the Company to utilize a portion of its tax attributes related to foreign tax credits in the United States that were previously fully reserved.

The cumulative amount of undistributed earnings of the Company’s non-U.S. Subsidiaries held for indefinite reinvestment is approximately $60.0 million, at December 31, 2023. If this amount were repatriated to the United States, the amount of incremental taxes would be approximately $6.0 million.

Amortization of finite-life intangible assets totaled $11.9 million, $9.7 million and $11.7 million for the years ended December 31, 2023, 2022 and 2021, respectively.

The estimated annual amortization expense for each of the five succeeding fiscal years are as follows (U.S. dollars in thousands):

Year Ending December 31,
2024	$	15,813
2025		12,745
2026		10,895
2027		8,340
2028		8,028

Indefinite life intangible assets are not amortized, rather they are subject to annual impairment tests. 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. In connection with the Company’s decision to exit the Grow Tech segment, a $3.8 million impairment charge related to other indefinite lived intangibles and a $5.2 million impairment charge related to other finite lived intangibles was recorded in the year ended December 31, 2021, see Note 20 for further discussion restructuring and impairment of the Grow Tech segment. During 2022, the Company recorded a $1.7 million impairment charge for other intangibles associated with our 2022 restructuring. See Note 20 for further discussion.
