Accounting Policies [Abstract] |
Consolidation, Policy [Policy Text Block] | Principles of Consolidation and Basis of Presentation The accompanying Consolidated Financial Statements include the accounts and operations of the Company. All inter-company accounts and transactions have been eliminated in consolidation. The accounting and reporting policies of the Company conform with accounting principles generally accepted in the United States of America (“US GAAP”).
Use of Estimates, Policy [Policy Text Block] | Use of Estimates The preparation of Consolidated Financial Statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. These estimates may be adjusted as more current information becomes available, and any adjustment could be significant.
Fiscal Period, Policy [Policy Text Block] | Fiscal Year The Company operates on a 52-53 week year, ending on the Saturday closest to December 31. Fiscal year 2020 was a 53-week year. Fiscal years 2019 and 2018 were 52-week years. Fiscal year 2020 covered the period December 29, 2019 to January 2, 2021 (hereinafter 2020). Fiscal year 2019 covered the period December 30, 2018 to December 28, 2019 (hereinafter 2019). Fiscal year 2018 covered the period December 31, 2017 to December 29, 2018 (hereinafter 2018).
Fair Value Measurement, Policy [Policy Text Block] | Fair Value Measurements The Company measures at fair value certain of its financial and non-financial assets and liabilities by using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, essentially an exit price, based on the highest and best use of the asset or liability. The levels of the fair value hierarchy are: ___________________________________
| (1) | The Company commenced operations in Germany, Spain, Italy, and Romania near the end of the second quarter of 2018.
| ● | Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.
| ● | Level 2 inputs are from other than quoted market prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.
| ● | Level 3 inputs are unobservable and are used to measure fair value in situations where there is little, if any, market activity for the asset or liability at the measurement date.
As of January 2, 2021 and December 28, 2019, the following financial assets and liabilities were measured at fair value on a recurring basis using the type of inputs shown:
|  |  |  |  |  | Fair Value Measurements Using |
|  | January 2, |  |  | Inputs |
|  | 2021 |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
Money market funds included in cash equivalents |  | $ | 224,092 |  |  | $ | 224,092 |  |  | $ | — |  |  | $ | — |
Foreign currency contracts included in other current liabilities |  |  | (1,470 | ) |  |  | — |  |  |  | (1,470 | ) |  |  | — |
|  | $ | 222,622 |  |  | $ | 224,092 |  |  | $ | (1,470 | ) |  | $ | — |

Money market funds included in cash equivalents |  | $ | 180,032 |  |  | $ | 180,032 |  |  | $ | — |  |  | $ | — |
Foreign currency contracts included in other current liabilities |  |  | (764 | ) |  |  | — |  |  |  | (764 | ) |  |  | — |
|  | $ | 179,268 |  |  | $ | 180,032 |  |  | $ | (764 | ) |  | $ | — |
There were no transfers of financial assets or liabilities between levels of the fair value hierarchy for the periods indicated. The majority of the Company’s non-financial assets, which include long-lived assets, are not required to be carried at fair value on a recurring basis. However, if an impairment charge is required, a non-financial asset would be written down to fair value. As of January 2, 2021 and December 28, 2019, there were no non-financial assets measured at fair value on a non-recurring basis.
Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair Value of Financial Instruments As of January 2, 2021 and December 28, 2019, the Company’s financial instruments include cash equivalents, accounts receivable, restricted cash, notes receivable, equity securities, accounts payable, and foreign currency contracts. The recorded values of cash equivalents, accounts receivable, restricted cash, and accounts payable approximate their fair values, based on their short-term nature. Historically, the carrying value of the notes receivable approximated fair value because the variable interest rates in the notes reflected current market rates. During 2017, an impairment was recorded on a note receivable based on the estimated recoverable amount using Level 3 inputs, which approximates fair value. This note receivable was settled during 2018.
Foreign Currency Transactions and Translations Policy [Policy Text Block] | Translation of Foreign Currencies The functional currency of the Company’s foreign subsidiaries is the local currency of their country of domicile. Assets and liabilities of the foreign subsidiaries are translated into U.S. dollar amounts at month-end exchange rates. Revenue and expense accounts are translated at the weighted-average rates for the monthly accounting period to which they relate. Equity accounts are translated at historical rates. Foreign currency translation adjustments are accumulated as a component of other comprehensive income. Gains and losses from foreign currency transactions are included in the “Other, net” component of Other income (expense) in the Company’s consolidated statements of comprehensive income.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less from the date of purchase to be cash equivalents. Cash equivalents as of January 2, 2021 and December 28, 2019 consisted primarily of money market fund investments and amounts receivable from credit card processors. Amounts receivable from credit card processors and other forms of electronic payment are considered cash equivalents because they are both short-term and highly liquid in nature and are typically converted to cash within three days of the sales transaction. Amounts receivable from credit card processors as of January 2, 2021 and December 28, 2019 totaled $15,424 and $12,619, respectively.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block] | Restricted Cash The Company is required to maintain cash deposits with banks in certain subsidiary locations for various operating purposes. The most significant of these cash deposits relates to a deposit held at a bank in China, the balance of which was $3,062 as of January 2, 2021, and $2,858 as of December 28, 2019. This deposit is required for the application of direct sales licenses by the Ministry of Commerce and the State Administration of Market Regulation (“SAMR”) of the People’s Republic of China, and will continue to be restricted during the periods while the Company holds these licenses.
Inventory, Policy [Policy Text Block] | Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using a standard costing system, which approximates the first-in, first-out method. The components of inventory cost include raw materials, labor, and overhead. Net realizable value is determined using various assumptions with regard to excess or slow-moving inventories, non-conforming inventories, expiration dates, current and future product demand, production planning, and market conditions. A change in any of these variables could result in an adjustment to inventory.
Accounts Receivable [Policy Text Block] | Accounts Receivable Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions and our customers’ financial condition, the amount of receivables in dispute, and the current receivables aging and current payment patterns. The Company reviews its allowance for doubtful accounts regularly. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Accounts Receivable is included in the “Prepaid expenses and other current assets” line item in the Company’s consolidated balance sheets.
Income Tax, Policy [Policy Text Block] | Income Taxes The Company accounts for income taxes using the asset and liability method, which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of the differences between the financial statement assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates that are expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax law is recognized in income in the period that includes the enactment date. Deferred tax expense or benefit is the result of changes in deferred tax assets and liabilities. The Company evaluates the probability of realizing the future benefits of its deferred tax assets and provides a valuation allowance for the portion of any deferred tax assets where the likelihood of realizing an income tax benefit in the future does not meet the “more-likely-than-not” criteria for recognition. The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the Financial Statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. The Company recognizes interest and penalties related to unrecognized tax benefits in income taxes.
Property, Plant and Equipment, Policy [Policy Text Block] | Property and Equipment Property and equipment are recorded at cost. Maintenance, repairs, and renewals, which neither materially add to the value of the property nor appreciably prolong its life, are charged to expense as incurred. Depreciation is provided in amounts sufficient to relate the cost of depreciable assets to operations over the estimated useful lives of the related assets. The straight-line method of depreciation and amortization is followed for financial statement purposes. Leasehold improvements are amortized over the shorter of the life of the respective lease or the useful life of the improvements. Property and equipment are reviewed for impairment whenever events or changes in circumstances exist that indicate the carrying amount of an asset may not be recoverable. When property and equipment are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations for the respective period.
Lessee, Leases [Policy Text Block] | Leases With the exception of the Company’s headquarters in Salt Lake City, Utah, and its facilities in New South Wales, Australia, and in Beijing and Tianjin, China, the Company leases its facilities. Each of the facility lease agreements is a non-cancelable operating lease generally structured with renewal options and expires prior to or during 2026. In connection with the production facilities in Beijing and Tianjin, China, the Company has prepaid land use rights, which represents a lease with the associated prepayment recorded as a Right-of-Use (“ROU”) asset. The Company also utilizes equipment under non-cancelable operating leases, expiring through 2025. At contract inception, the Company determines whether an arrangement is or contains a lease and whether the lease should be classified as an operating or a financing lease. A contract is or contains a lease if the contract conveys the right to control the use of the identified asset for a period of time in exchange for consideration. Control is determined based on the right to obtain all of the economic benefits from use of the identified asset and the right to direct the use of the identified asset. ROU assets for operating leases represent the right to use an underlying asset for the lease term, and operating lease liabilities represent the obligation to make lease payments. Lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date for leases exceeding 12 months. Minimum lease payments include only the fixed lease component of the agreement, as well as any variable rate payments that depend on an index, initially measured using the index at the lease commencement date. Non-lease components are accounted for separately from the fixed lease component for all leases. Most of the Company’s leases do not provide an implicit rate that can readily be determined. Therefore, the applied discount rate is based on the Company’s incremental borrowing rate, which is determined using its credit rating and other information available as of the commencement date and is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. Lease terms may include options to renew, which the Company factors into the determination of the lease term when it is reasonably certain that the Company will exercise that option. The ROU asset is measured at the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. Operating lease expense is recognized on a straight-line basis over the lease term and is included in “Cost of sales” and “Selling, general and administrative” line items in the Company’s consolidated statements of comprehensive income. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and the expense for these short-term leases is recognized on a straight-line basis over the lease term. The Company monitors for events or changes in circumstances that require a reassessment of its leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the ROU asset unless doing so would reduce the ROU asset to an amount less than zero, in which case the remaining adjustment would be recorded in the consolidated statements of comprehensive income. Results for reporting periods beginning on and after December 30, 2018 are presented under ASC 842, while prior period amounts continue to be presented in accordance with the Company’s historical accounting under ASC Topic 840.
Financing Receivable [Policy Text Block] | Notes Receivable In a prior year, the Company extended non-revolving credit to a former supplier to allow them to acquire equipment that was necessary to manufacture the USANA nutrition bars, which was secured by the equipment. This relationship was intended to provide improved supply chain stability for USANA and create a mutually beneficial relationship between the parties. Interest accrued at an annual interest rate of LIBOR plus 400 basis points. The note had a maturity date of February 1, 2024 and was to be repaid by a combination of cash payments and credits for the manufacture of USANA’s nutrition bars. There was no prepayment penalty. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments in accordance with the contractual terms of the loan. Factors considered in determining impairment include payment status, collateral value and the probability of collecting payments when due. During the first half of 2017, the Company experienced challenges with the former supplier of nutrition bars and subsequently determined to no longer use this supplier. The Company evaluated the recoverability of the note receivable from this supplier and recorded impairments totaling $2,734 during 2017. The total contractual unpaid principal balance, including accrued unpaid interest on the note receivable from this supplier as of December 30, 2017 was $6,734. During 2018, the Company reached a settlement with the supplier to terminate the relationship and received $4,800 in cash as payment in full under the terms of the settlement.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block] | Goodwill Goodwill represents the excess of the purchase price over the fair market value of identifiable net assets of acquired companies. Goodwill is not amortized, but rather is tested at the reporting unit level at least annually for impairment or more frequently if triggering events or changes in circumstances indicate impairment. Initially, qualitative factors are considered to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Some of these qualitative factors may include macroeconomic conditions, industry and market considerations, a change in financial performance, entity-specific events, a sustained decrease in share price, and consideration of the difference between the fair value and carrying amount of a reporting unit as determined in the most recent quantitative assessment. If, through this qualitative assessment, the conclusion is made that it is more likely than not that a reporting unit’s fair value is less than its carrying amount, a quantitative impairment analysis is performed. This analysis involves estimating the fair value of a reporting unit using widely accepted valuation methodologies including the income and market approaches, which requires the use of estimates and assumptions. These estimates and assumptions include revenue growth rates, discounts rates, and determination of appropriate market comparables. If the fair value of the reporting unit is less than its carrying amount, an impairment loss is recognized in an amount equal to the excess of the carrying amount over the fair value of the reporting unit, not to exceed the carrying amount of the goodwill. During 2020, 2019, and 2018, no impairment of goodwill was recorded.
Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block] | Intangible Assets Intangible assets represent amortized and indefinite-lived intangible assets acquired in connection with the purchase of the Company’s China subsidiary in 2010. Amortized intangible assets are amortized over their related useful lives, using a straight-line or accelerated method consistent with the underlying expected future cash flows related to the specific intangible asset. Amortized intangible assets are reviewed for impairment whenever events or changes in circumstances exist that indicate the carrying amount of an asset may not be recoverable. When indicators of impairment exist, an estimate of undiscounted net cash flows is used in measuring whether the carrying amount of the asset or related asset group is recoverable. Measurement of the amount of impairment, if any, is based upon the difference between the asset or asset group’s carrying value and fair value. Fair value is determined through various valuation techniques, including market and income approaches as considered necessary. Indefinite-lived intangible assets are not amortized; however, they are tested at least annually for impairment or more frequently if events or changes in circumstances exist that may indicate impairment. Initially, qualitative factors are considered to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount. If, through this qualitative assessment, the conclusion is made that it is more likely than not that an indefinite-lived intangible asset’s fair value is less than its carrying amount, a quantitative impairment analysis is performed by comparing the indefinite-lived intangible asset’s carrying amount to its fair value. The fair value for indefinite-lived intangible assets is determined through various valuation techniques, including market and income approaches as considered necessary. The amount of any impairment is measured as the difference between the carrying amount and the fair value of the impaired asset. During 2020, 2019, and 2018, no impairment of indefinite-lived intangible assets was recorded.
Equity Securities without Readily Determinable Fair Value [Policy Text Block] | Investment in Equity Securities Equity securities (“securities”) without readily determinable fair value that are not eligible to be measured in accordance with the net asset value practical expedient qualify for an election to initially estimate fair value using the measurement alternative at its cost. During the fourth quarter, the Company entered into a strategic collaboration and made a minority investment in a privately held company, which totaled $20,000 and is included in the “Other assets” line item on the Company’s consolidated balance sheets. The Company, at the time of the investment, elected to apply the measurement alternative, which may be applied to an equity interest on an instrument-by-instrument basis. Dividends received are reported in earnings. The initial value of the securities are remeasured to fair value if the securities are impaired or if observable price changes occur. These events are continually monitored and assessed at each reporting period. If a readily determinable fair value becomes available for the securities or observable price changes for the identical or a similar investment of the same issuer occur, the securities are measured at fair value as of the date the observable change occurred. Any resulting gains or losses on the securities for which the observable price changes occur will be recorded in net earnings. During 2020, no such observable price changes occurred. At each reporting period a qualitative assessment is made to consider impairment indicators to determine whether the securities are impaired. Impairment indicators may include but are not limited to earnings performance, business prospects by the investee, cash flows from operations, working capital, and noncompliance with debt covenants. If this qualitative assessment indicates impairment, fair value is determined and an impairment loss equal to the difference between the fair value of the investment and its carrying amount is recognized in net income. During 2020, no impairment of securities was recorded.
Self Insurance Reserve [Policy Text Block] | Self-Insurance The Company is self-insured, up to certain limits, for employee group health claims. The Company has purchased stop-loss insurance on both an individual and an aggregate basis, which will reimburse the Company for individual claims in excess of $150 and aggregate claims that are greater than $12,491. A liability is accrued for all unpaid claims. Total expense under this self-insurance program was $11,798, $11,846, and $10,869 in 2020, 2019, and 2018, respectively.
Derivatives, Policy [Policy Text Block] | Derivative Financial Instruments The Company’s risk management strategy includes the select use of derivative instruments to reduce the effects of volatility in foreign currency exchange exposure on operating results and cash flows. In accordance with the Company’s risk management policies, the Company does not hold or issue derivative instruments for trading or speculative purposes. The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. When the Company becomes a party to a derivative instrument and intends to apply hedge accounting, the Company formally documents the hedge relationship and the risk management objective for undertaking the hedge, the nature of risk being hedged, and the hedged transaction, which includes designating the instrument for financial reporting purposes as a fair value hedge, a cash flow hedge, or a net investment hedge. The Company also documents how the hedging instrument’s effectiveness in offsetting the hedged risk will be assessed prospectively and retrospectively, and a description of the method used to measure ineffectiveness. The Company periodically uses derivative instruments to hedge the foreign currency exposure of its net investment in foreign subsidiaries into U.S. dollars. Initially, the Company records derivative assets on a gross basis in its consolidated balance sheets. Subsequently the fair value of derivatives is measured for each reporting period. The effective portion of gains and losses attributable to these net investment hedges is recorded to foreign currency translation adjustment (“FCTA”) within accumulated other comprehensive income (loss) (“AOCI”) to offset the change in the carrying value of the net investment being hedged, and will subsequently be reclassified to net earnings in the period in which the hedged investment is either sold or substantially liquidated. During 2020 and 2019, the Company entered into and settled a European option designated as a net investment hedge with a notional amount of $90,000 and $110,000 and realized a net gain of $846 and $276, respectively, which is recorded to FCTA within AOCI. The Company assessed hedge effectiveness under the forward rate method, determining the hedging instruments were highly effective. As of January 2, 2021 and December 28, 2019, there were no derivatives outstanding for which the Company has applied hedge accounting.
Stockholders' Equity, Policy [Policy Text Block] | Common Stock Share Repurchases The Company has a stock repurchase plan in place that has been authorized by the Board of Directors. As of January 2, 2021, $72,971 is available to repurchase shares under this plan. The excess of the repurchase price over par value is allocated between additional paid-in capital and retained earnings on a pro-rata basis. There currently is no expiration date on the remaining approved repurchase amount and no requirement for future share repurchases. Subsequent to January 2, 2021, on February 9, 2021, the Company's Board of Directors authorized an increase in the amount available under the share repurchase plan to a total of $150,000. The authorization is inclusive of the $72,971 that was remaining under the prior authorization at January 2, 2021.
Revenue from Contract with Customer [Policy Text Block] | Revenue Recognition Revenue is recognized when, or as, control of a promised product or service transfers to a customer, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring those products or services. Revenue excludes taxes that have been assessed by governmental authorities and that are directly imposed on revenue-producing transactions between the Company and its customers, including sales, use, value-added, and some excise taxes. Revenue recognition is evaluated through the following five-step process:
| 1) | identification of the contract with a customer;
| 2) | identification of the performance obligations in the contract;
| 3) | determination of the transaction price;
| 4) | allocation of the transaction price to the performance obligations in the contract; and
| 5) | recognition of revenue when or as a performance obligation is satisfied.
Product Revenue A majority of the Company’s sales are for products sold at a point in time and shipped to customers, for which control is transferred to the customer as goods are delivered to the third party carrier for shipment. The Company receives payment, primarily via credit card, for the sale of products at the time customers place orders and payment is required prior to shipment. The Company does not recognize assets associated with costs to obtain or fulfill a contract with a customer. The Company’s product sales contracts include terms that could cause variability in the transaction price for items such as discounts, credits, or sales returns. Accordingly, the transaction price for product sales includes estimates of variable consideration to the extent it is probable that a significant reversal of revenue recognized will not occur. At the time of sale, the Company estimates a refund liability for the variable consideration based on historical experience, which is recorded within the “Other current liabilities” line item in the consolidated balance sheet. Initial product orders with a new customer may include multiple performance obligations related to sales discounts earned under the Company’s initial order reward program. Under this program, the customer receives an option to apply the discounts earned on the initial order to two subsequent Auto Orders, which conveys a material right to the customer. As such, the initial order transaction price is allocated to each separate performance obligation based on its relative standalone selling price and is recognized as revenue as each performance obligation is satisfied. From time to time, the Company will run specific product promotions, such as, discounted product or customer incentive promotions, which are classified as Associate incentives. These incentives and promotions are recorded at the point of corresponding product purchase. Associate incentives represent consideration paid to a customer and include all forms of commissions, and other incentives paid to our Associates. With the exception of commissions paid to Associates on personal purchases, which are considered a sales discount and are reported as a reduction to net sales, the incentives are paid for distinct services related to the Company’s product sales and are recorded as an expense when revenue for the goods is recognized. Shipping and handling activities are performed upon delivery to the third party carrier for shipment. The Company accounts for these activities as fulfillment costs. Therefore, the Company recognizes the costs of these activities when revenue for the goods is recognized. Shipping and handling costs are included in cost of sales for all periods presented. With respect to will-call orders, the Company periodically assesses the likelihood that customers will exercise their contractual right to pick up orders and revenue is recognized when the likelihood that customers will pick up orders is remote. Other Revenue Other types of revenue include fees, which are paid by the customer at the beginning of the service period, for access to online customer service applications and annual account renewal fees for Associates, for which control is transferred over time as services are delivered and are recognized as revenue on a straight-line basis over the term of the respective contracts. The following table presents Other Revenue for the periods indicated:
|  | Year Ended |
|  | 2020 |  |  | 2019 |  |  | 2018 |
Other Revenue |  | $ | 3,805 |  |  | $ | 3,059 |  |  | $ | 4,007 |
Revenue Disaggregation Disaggregation of revenue by geographical region and major product line is included in Note L – Segment Information. Contract Balances When the timing of our provision of goods or services is different from the timing of the payments made by our customers, we recognize either a contract asset (performance precedes contractual due date) or a contract liability (customer payment precedes performance). Contract liabilities relate to deferred revenue for product sales for customer payments received in advance of shipment, for outstanding material rights under the initial order program, and for services where the performance obligations are satisfied over time as services are delivered. Contract liabilities are recorded as deferred revenue within the "Other current liabilities" line item in the consolidated balance sheets. The Company typically does not have contract assets based on the payment terms included in the Company’s contracts and the balance of contract assets was $0 at January 2, 2021 and December 28, 2019. The following table provides information about contract liabilities from contracts with customers, including significant changes in the contract liabilities balances during the period.
|  | January 2, |  |  | December 28, |
|  | 2021 |  |  | 2019 |
Contract liabilities at beginning of period |  | $ | 13,852 |  |  | $ | 15,055 |
Increase due to deferral of revenue at period end |  |  | 15,952 |  |  |  | 13,852 |
Decrease due to beginning contract liabilities recognized as revenue |  |  | (13,852 | ) |  |  | (15,055 | )
Contract liabilities at end of period |  | $ | 15,952 |  |  | $ | 13,852 |
Product Return [Policy Text Block] | Product Return Policy All product orders that are unused and returned within the first 30 days following purchase are refunded at 100% of the sales price. All product orders that are unused and resalable are refunded up to one year from the date of purchase at 100% of the sales price. This standard policy differs in a few of our international markets due to the regulatory environment in those markets. Depending upon the conditions under which product was returned, customers may either receive a refund based on their original form of payment, or credit on account for a product exchange. The Company monitors Associate activity to ensure that all such practices are in line with established Company policies. Product returns totaled approximately 0.7% of net sales in 2020, 2019, and 2018.
Associate Incentives [Policy Text Block] | Associate Incentives Associate incentives expenses include all forms of commissions, and other incentives paid to our Associates, less commissions paid to Associates on personal purchases, which are considered a sales discount and are reported as a reduction to net sales.
Selling, General and Administrative Expenses, Policy [Policy Text Block] | Selling, General and Administrative Selling, general and administrative expenses include wages and benefits, depreciation and amortization, rents and utilities, Associate event costs, advertising and professional fees, marketing, and research and development expenses.
Share-based Payment Arrangement [Policy Text Block] | Equity-Based Compensation The Company records compensation expense in the Financial Statements for equity-based awards based on the grant date fair value, which for restricted stock units is the closing market value of the Company’s common stock on the date of the grant. The grant date fair value of each stock-settled stock appreciation right is based upon the Black-Scholes option pricing model. Equity-based compensation expense is recognized under the straight-line method over the period that service is provided, which is generally the vesting term. Further information regarding equity awards can be found in Note K – Equity-Based Compensation.
Advertising Cost [Policy Text Block] | Advertising Advertising costs are charged to expense as incurred and are presented as part of the “Selling, general and administrative” line item. Advertising expense totaled $9,853, $11,615, and $10,345 in 2020, 2019, and 2018, respectively.
Research and Development Expense, Policy [Policy Text Block] | Research and Development Research and development costs are charged to expense as incurred and are presented as part of the “Selling, general and administrative” line item. Research and development expense totaled $10,633, $10,259, and $10,242 in 2020, 2019, and 2018, respectively.
Earnings Per Share, Policy [Policy Text Block] | Earnings Per Share Basic earnings per common share (EPS) are based on the weighted-average number of common shares that were outstanding during each period. Diluted EPS include the effect of potentially dilutive common shares calculated using the treasury stock method, which include in-the-money, equity-based awards that have been granted but have not been issued. When there is a loss, potential common shares are not included in the computation of diluted EPS, because to do so would be anti-dilutive.
New Accounting Pronouncements, Policy [Policy Text Block] | Recent Accounting Pronouncements Adopted accounting pronouncements In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 modifies the disclosure requirements for fair value measurements. The modifications removed the following disclosure requirements: (i) the amount of, and reasons for, transfers between Level 1 and Level 2 of the fair value hierarchy; (ii) the policy for timing of transfers between levels; and (iii) the valuation processes for Level 3 fair value measurements. This ASU added the following disclosure requirements: (i) the changes in unrealized gains and losses for the period included in other comprehensive income (“OCI”) for recurring Level 3 fair value measurements held at the end of the reporting period; and (ii) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted ASU 2018-13 during the first quarter of 2020 and the adoption of the standard did not have an impact on its Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-15, “Intangibles - Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The capitalized implementation costs of a hosting arrangement that is a service contract will be expensed over the term of the hosting arrangement. For public business entities, the amendments in this ASU are effective for annual and interim periods beginning after December 15, 2019. Early adoption is permitted, including adoption in any interim period. The amendments can be applied either retrospectively or prospectively to all implementation costs incurred after the adoption date. The Company adopted ASU 2018-15 during the first quarter of 2020 and the adoption of the standard did not have an impact on its Consolidated Financial Statements. In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” ASU 2020-04 is intended to provide temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. This ASU is effective upon issuance through December 31, 2022 on a prospective basis. The Company will evaluate transactions or contract modifications occurring as a result of reference rate reform and determine whether to apply the optional guidance on an ongoing basis. The Company adopted ASU 2020-04 during the first quarter of 2020 and the adoption of the standard did not have an impact on its Consolidated Financial Statements. In January 2020, the FASB issued ASU No. 2020-01, “Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815).” ASU 2020-01 clarifies the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. The amendments in this ASU affect all entities that apply the guidance in Topics 321, 323, and 815 and (1) elect to apply the measurement alternative or (2) enter into a forward contract or purchase an option to purchase securities that, upon settlement of the forward contract or exercise of the purchased option, would be accounted for under the equity method of accounting. The Company has elected to apply the measurement alternative to certain securities held for investment but has not entered into any derivatives to purchase securities. This ASU clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. For public business entities, the amendments in this ASU are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted, including early adoption in an interim period and for public business entities for periods for which financial statements have not yet been issued. The amendments in this ASU should be applied prospectively and an entity should apply the amendments at the beginning of the interim period that includes the adoption date. The Company elected to early adopt this ASU during the fourth quarter of 2020 and the adoption of the standard did not have an impact on its Consolidated Financial Statements. Issued accounting pronouncements not yet adopted In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 is intended to simplify various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and clarifying certain aspects of the current guidance to promote consistency among reporting entities. The amendments in this ASU are effective for annual periods beginning after December 15, 2020 and interim periods within those annual periods, with early adoption permitted. An entity that elects early adoption must adopt all the amendments in the same period. Most amendments within this ASU are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. The Company does not expect the adoption of ASU 2019-12 will have a material impact on its Consolidated Financial Statements. No other new accounting pronouncement issued or effective during the fiscal year had, or is expected to have, a material impact on our Consolidated Financial Statements.
