Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Mannatech, Incorporated (together with its subsidiaries, the “Company”), located in Flower Mound, Texas, was incorporated in the state of Texas on November 4, 1993 and is listed on The Nasdaq Global Select Market under the symbol “MTEX”. The Company develops, markets, and sells high-quality, proprietary nutritional supplements, topical and skin care and anti-aging products, and weight-management products. We currently sell our products into three regions: (i) the Americas (the United States, Canada, Colombia and Mexico); (ii) EMEA (Austria, the Czech Republic, Denmark, Estonia, Finland, Germany, the Republic of Ireland, Namibia, the Netherlands, Norway, South Africa, Spain, Sweden and the United Kingdom); and (iii) Asia/Pacific (Australia, Japan, New Zealand, the Republic of Korea, Singapore, Taiwan, Hong Kong, and China). Associates and now preferred customers purchase the Company’s products at published wholesale prices. The Company cannot distinguish products sold for personal use from other sales, when sold to associates, because it is not involved with the products after delivery, other than usual and customary product warranties and returns. Only associates are eligible to earn commissions and incentives. The Company operates a non-direct selling business in mainland China. Our subsidiary in China, Meitai Daily Necessity & Health Products Co., Ltd. (“Meitai”), is operating as a traditional retailer under a cross-border e-commerce model in China. Meitai cannot legally conduct a direct selling business in China unless it acquires a direct selling license in China. Principles of Consolidation The consolidated financial statements and footnotes include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of the Company’s consolidated financial statements in accordance with generally accepted accounting principles requires the use of estimates that affect the reported value of assets, liabilities, revenues and expenses. These estimates are based on historical experience and various other factors. The Company continually evaluates the information used to make these estimates as the business and economic environment changes. Historically, actual results have not varied materially from the Company’s estimates and the Company does not currently anticipate a significant change in its assumptions related to these estimates. However, actual results may differ from these estimates under different assumptions or conditions. The use of estimates is pervasive throughout the consolidated financial statements, but the accounting policies and estimates considered the most significant are described in this note to the consolidated financial statements, Organization and Summary of Significant Accounting Policies . Foreign Currency Translation The United States dollar is the functional currency for the majority of the Company’s foreign subsidiaries. As a result, nonmonetary assets and liabilities are remeasured at their approximate historical rates, monetary assets and liabilities are remeasured at exchange rates in effect at the end of the year, and revenues and expenses are remeasured at weighted-average exchange rates for the year. The local currency is the functional currency of our subsidiaries in Columbia, Japan, Republic of Korea, Taiwan, Norway, Denmark, Sweden, Mexico and China. These subsidiaries’ assets and liabilities are translated into United States dollars at exchange rates existing at the balance sheet dates, revenues and expenses are translated at weighted-average exchange rates, and shareholders’ equity and intercompany balances are translated at historical exchange rates. The foreign currency translation adjustment is recorded as a separate component of shareholders’ equity and is included in accumulated other comprehensive income. Transaction losses totaled approximately $0.7 million for the year ended December 31, 2019 and transaction gains totaled approximately $0.3 million for the year ended December 31, 2018 , and are included in other expense, net in the Company’s consolidated statements of operations. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company includes in its cash and cash equivalents credit card receivables due from its credit card processor, as the cash proceeds from credit card receivables are received within 24 to 72 hours. As of December 31, 2019 and 2018 , credit card receivables were $0.7 million and $1.6 million , respectively, and cash and cash equivalents held in bank accounts in foreign countries totaled $18.2 million and $19.9 million , respectively. The Company invests cash in liquid instruments, such as money market funds and interest bearing deposits. The Company also holds cash in high quality financial institutions and does not believe it has an excessive exposure to credit concentration risk. At December 31, 2019, a portion of our cash and cash equivalent balances were concentrated within the Republic of South Korea, with total net assets within this foreign location totaling $19.2 million . In addition, for the year ended December 31, 2019, a concentrated portion of our operating cash flows were earned from operations within the Republic of South Korea. An adverse change in economic conditions within the Republic of South Korea could negatively affect the Company’s results of operations. Restricted Cash The Company is required to restrict cash for: (i) direct selling insurance premiums and credit card sales in the Republic of Korea; (ii) reserve on credit card sales in the United States and Canada; and (iii) Australia building lease collateral. As of December 31, 2019 and 2018 , our total restricted cash was $6.2 million and $8.7 million , respectively. The Company classifies the restricted cash held in Korea and Australia as long-term since it relates to assets and services contracted for longer than one year. The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Company's consolidated balance sheets to the total amount presented in the consolidated statement of cash flows ( in thousands ): December 31, 2019 December 31, 2018 Cash and cash equivalents at beginning of period $ 21,845 $ 37,682 Current restricted cash at beginning of period 1,514 1,514 Long-term restricted cash at beginning of period 7,225 7,565 Cash, cash equivalents, and restricted cash at beginning of period $ 30,584 $ 46,761 Cash and cash equivalents at end of period $ 24,762 $ 21,845 Current restricted cash at end of period 943 1,514 Long-term restricted cash at end of period 5,295 7,225 Cash, cash equivalents, and restricted cash at end of period $ 31,000 $ 30,584 Accounts Receivable Accounts receivable are carried at their estimated collectible amounts. Receivables are created upon shipment of an order if the credit card payment is rejected or does not match the order total. As of December 31, 2019 and 2018 , receivables consisted primarily of amounts due from preferred customers and associates. The Company periodically evaluates its receivables for collectability based on historical experience, recent account activities, and the length of time receivables are past due and writes-off receivables when they become uncollectible. As of December 31, 2019 and 2018 , the Company held an allowance for doubtful accounts of $0.7 million and $0.8 million , respectively. Inventories Inventories consist of raw materials, finished goods, and promotional materials that are stated at the lower of cost (using standard costs that approximate average costs) or net realizable value. The Company periodically reviews inventories for obsolescence and any inventories identified as obsolete are reserved or written off. Prepaid Expenses and Other Current Assets Prepaid expenses and other current assets were $2.2 million and $3.4 million at December 31, 2019 and 2018 , respectively. Included in the December 31, 2019 and 2018 balances were $0.8 million and $1.0 million in other prepaid assets, respectively. Also included in the balances at December 31, 2019 and 2018 were $0.7 million and $1.8 million for other prepaid deposits, respectively. At December 31, 2019 the balance in prepaid inventory was $0.7 million . Property and Equipment Property and equipment are stated at cost, less accumulated depreciation and amortization computed using the straight-line method over the estimated useful life of each asset. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the improvements. Expenditures for maintenance and repairs are charged to expense as incurred. The cost of property and equipment sold or otherwise retired and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in other operating costs in the accompanying consolidated statements of operations. The estimated useful lives of fixed assets are as follows: Estimated useful life Office furniture and equipment 5 to 7 years Computer hardware and software 3 to 5 years Automobiles 3 to 5 years Leasehold improvements (1) 2 to 10 years (1) The Company amortizes leasehold improvements over the shorter of the useful estimated life of the leased asset or the lease term. Property and equipment are reviewed for impairment whenever an event or change in circumstances indicates that the carrying amount of an asset or group of assets may not be recoverable. The impairment review includes a comparison of future projected cash flows generated by the asset or group of assets with its associated net carrying value. If the net carrying value of the asset or group of assets exceeds expected cash flows (undiscounted and without interest charges), an impairment loss is recognized to the extent the carrying amount of the asset exceeds its fair value. Other Assets At December 31, 2019 and 2018 , other assets were $9.6 million and $3.9 million , respectively. Included in the December 31, 2019 and 2018 balances were deposits for building leases in various locations of $2.2 million and $2.0 million , respectively. Also included in the December 31, 2019 and 2018 balances were $1.6 million and $1.7 million , respectively, representing a deposit with Mutual Aid Cooperative and Consumer in the Republic of Korea, an organization established by the Republic of Korea’s Fair Trade Commission’s approval to compensate and protect consumers who participate in network marketing activities from damages. Other assets at each of December 31, 2019 and 2018 also include $0.2 million of indefinite lived intangible assets relating to the Manapol ® powder trademark. The December 31, 2019 balance also includes $5.6 million of operating lease right-of-use assets. See Note 5, Leases for more information. Notes Payable Notes payable were $1.1 million and $1.6 million as of December 31, 2019 and December 31, 2018 , respectively, as a result of funding from a capital financing agreement related to our investment in leasehold improvements, computer hardware and software and other financing arrangements. Payments are made monthly according to the terms of the agreements which have a weighted average effective interest rate of 5.8% and are collateralized by leasehold improvements and computer hardware and software. At December 31, 2019 , the current portion was $0.7 million and the long-term portion was $0.4 million . At December 31, 2018 , the current portion was $0.7 million and the long-term portion was $0.9 million . Other Long-Term Liabilities Other long-term liabilities were $6.2 million and $2.3 million for the years ending December 31, 2019 and 2018 , respectively. At December 31, 2018, we recorded $ 1.3 million of lease incentive obligation for leasehold improvements at our corporate headquarters. At each of December 31, 2019 and 2018 , we recorded $0.2 million , respectively, in other long-term liabilities related to uncertain income tax positions (see Note 7, Income Taxes ). Certain operating leases for the Company’s regional office facilities contain a restoration clause that requires the Company to restore the premises to its original condition. At December 31, 2019 and 2018 , accrued restoration costs related to these leases amounted to $0.3 million and $0.4 million , respectively. At December 31, 2019 and 2018 , government mandated severance accruals in certain international offices amounted to $0.4 million and $0.3 million , respectively. The Company also recorded a long-term liability for an estimated defined benefit obligation related to a non-U.S. defined benefit plan for its Japan operations of $0.3 million and $0.4 million as of December 31, 2019 and 2018 , respectively (See Note 9, Employee Benefit Plans ). The December 31, 2019 balance also includes $5.3 million of long-term operating lease right-of-use obligations. See Note 5, Leases for more information. Revenue Recognition The Company’s revenue is derived from sales of individual products and associate fees or, in certain geographic markets, starter and renewal packs. Substantially all of the Company’s product sales are made at published wholesale prices to associates and preferred customers. The Company records revenue net of any sales taxes and records a reserve for expected sales returns based on its historical experience. The Company recognizes revenue from shipped products when control of the product transfers to the customer, thus the performance obligation is satisfied. Corporate-sponsored event revenue is recognized when the event is held. Orders placed by associates or preferred customers constitute our contracts. Product sales placed in the form of an automatic order contain two performance obligations - a) the sale of the product and b) the loyalty program. For these contracts, the Company accounts for each of these obligations separately as they are each distinct. The transaction price is allocated between the product sale and the loyalty program on a relative standalone selling price basis. Sales placed through a one-time order contain only the first performance obligation noted above - the sale of the product. The Company provides associates with access to a complimentary three-month package for the Success Tracker TM and Mannatech+ online business tools with the first payment of an associate fee. The first payment of an associate fee contains three performance obligations a) the associate fee, whereby the Company provides an associate with the right to earn commissions, bonuses and incentives for a year, b) three months of complimentary access to utilize the Success Tracker™ online tool and c) three months of complimentary access to utilize the Mannatech+ online business tool. The transaction price is allocated between the three performance obligations on a relative standalone selling price basis. Associates do not have complimentary access to online business tools after the first contractual period. With regard to both of the aforementioned contracts, the Company determines the standalone selling prices based on our overall pricing objectives, taking into consideration market conditions and other factors, including the value of the contracts. Our sales mix for the years ended December 31, was as follows (in millions, except percentages) : 2019 Percentage 2018 Percentage Consolidated product sales $ 154.6 98.0 % $ 170.2 98.0 % Consolidated pack sales and associate fees (a) 2.3 1.5 % 2.5 1.5 % Consolidated other 0.8 0.5 % 0.9 0.5 % Total consolidated net sales $ 157.7 100.0 % $ 173.6 100.0 % Revenues by reporting segment are presented in Note 15 of our consolidated financial statements. We believe that the disaggregation of our revenues as reflected above, coupled with further discussion below, and the reporting segment in Note 15, depicts how the nature, amount, timing and uncertainty of our revenues and cash flows are affected by economic factors. Deferred Commissions The Company defers commissions on (i) the sales of products shipped but not received by customers by the end of the respective period and (ii) the loyalty program. Deferred commissions are incremental costs and are amortized to expense consistent with how the related revenue is recognized. Deferred commissions were $1.8 million and $2.4 million at December 31, 2019 and December 31, 2018 , respectively. The full $2.4 million balance at December 31, 2018 was amortized to commissions expense for the twelve months ended December 31, 2019 . Deferred Revenue The Company defers certain components of its revenue. Deferred revenue consisted of: (i) sales of products shipped but not received by the customers by the end of the respective period; (ii) revenue from the loyalty program; (iii) prepaid registration fees from customers planning to attend a future corporate-sponsored event; and (iv) prepaid annual associate fees. At December 31, 2019 and December 31, 2018 , the Company’s deferred revenue was $4.4 million and $5.3 million , respectively. The full $5.3 million balance at December 31, 2018 was recognized as revenue for the twelve months ended December 31, 2019 . The Company's customer loyalty program conveys a material right to the customer as it provides the promise to redeem loyalty points for the purchase of products, which is based on earning points through placing consecutive qualified automatic orders. The Company factors in breakage rates, which is the percentage of the loyalty points that are expected to be forfeited or expire, for purposes of revenue recognition. Breakage rates are estimated based on historical data and can be reasonably and objectively determined. The deferred revenue associated with the loyalty program at December 31, 2019 and December 31, 2018 was $3.1 million and $4.2 million , as follows: Loyalty program (in thousands) Loyalty deferred revenue as of January 1, 2018 $ 6,406 Loyalty points forfeited or expired (4,332 ) Loyalty points used (11,398 ) Loyalty points vested 12,469 Loyalty points unvested 1,086 Loyalty deferred revenue as of December 31, 2018 $ 4,231 Loyalty deferred revenue as of January 1, 2019 $ 4,231 Loyalty points forfeited or expired (4,348 ) Loyalty points used (9,127 ) Loyalty points vested 11,320 Loyalty points unvested 1,051 Loyalty deferred revenue as of December 31, 2019 $ 3,127 Sales Refund and Allowances The Company utilizes the expected value method to estimate the sales returns and allowance liability by taking the weighted average of the sales return rates over a rolling six-month period. The Company allocates the total amount recorded within the sales return and allowance liability as a reduction of the overall transaction price for the Company’s product sales. The Company deems the sales refund and allowance liability to be a variable consideration. Historically, our sales returns have not materially changed through the years, as the majority of our customers who return their merchandise do so within the first 90 days after the original sale. Sales returns have historically averaged 1.5% or less of our gross sales. For the years ended December 31, 2019 and December 31, 2018 , our sales return reserve consisted of the following (in thousands) : Sales reserve as of January 1, 2018 $ 117 Provision related to sales made in current period 1,198 Adjustment related to sales made in prior periods (10 ) Actual returns or credits related to current period (1,125 ) Actual returns or credits related to prior periods (104 ) Sales reserve as of December 31, 2018 $ 76 Sales reserve as of January 1, 2019 $ 76 Provision related to sales made in current period 1,037 Adjustment related to sales made in prior periods 31 Actual returns or credits related to current period (973 ) Actual returns or credits related to prior periods (103 ) Sales reserve as of December 31, 2019 $ 68 Shipping and Handling Costs The Company records inbound freight as a component of inventory and cost of sales. The Company records freight and shipping fees collected from its customers as fulfillment costs. Freight and shipping fees are not deemed to be separate performance obligations as these activities occur before the customer receives the product. Commission and Incentive Expenses Associates earn commissions and incentives based on their direct and indirect commissionable net sales over each month of the fiscal year. The Company accrues commissions and incentives when earned by associates and pays commissions on product and pack sales on a monthly basis. Advertising Expenses The Company expenses advertising and promotions in selling and administrative expenses when incurred. Advertising and promotional expenses were approximately $3.5 million and $5.6 million for the years ended December 31, 2019 and 2018 , respectively. Educational and promotional items, called sales aids, are sold to associates to assist in their sales efforts and are included in inventories and charged to cost of sales when sold. Research and Development Expenses The Company expenses research and development expenses as incurred. Research and development expenses related to new product development, enhancement of existing products, clinical studies and trials, Food and Drug Administration compliance studies, general supplies, internal salaries, third-party contractors, and consulting fees were approximately $1.1 million and $1.0 million , respectively, for the years ended December 31, 2019 and 2018 . Salaries and contract labor are included in selling and administrative expenses and all other research and development costs are included in other operating costs. Stock-Based Compensation The Company currently has one active stock-based compensation plan, the Mannatech, Incorporated 2017 Stock Incentive Plan, which was adopted by the Company’s Board of Directors (the "Board") on April 17, 2017 and was approved by its shareholders on June 8, 2017 , and subsequently amended by the Board at its February 2019 special meeting, which amendment was approved by the Company's shareholders on June 11, 2019 (as amended, the "2017 Plan"). The 2017 Plan supersedes the Mannatech, Incorporated 2008 Stock Incentive Plan (as amended the "2008 Plan"), which was set to expire on February 20, 2018 . The Board has reserved a maximum of 370,000 shares of our common stock that may be issued under the 2017 Plan (subject to adjustments for stock splits, stock dividends or other changes in corporate capitalization). The 2017 Plan provides for grants of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance stock and performance stock units to our employees, board members, and consultants. However, only employees of the Company and its corporate subsidiaries are eligible to receive incentive stock options. The exercise price per share for all stock options will be no less than the market value of a share of common stock on the date of grant. Any incentive stock option granted to an employee owning more than 10% of our common stock will have an exercise price of no less than 110% of our common stock’s market value on the grant date. The majority of stock options vest over two or three years, and generally are granted with a term of ten years, or five years in the case of an incentive option granted to an employee who owns more than 10% of our common stock. At date of grant, the Company determines the fair value of the stock option award and recognizes compensation expense over the requisite service period, or the vesting period of the award. The fair value of the stock option award is calculated using the Black-Scholes option-pricing model. The Company records stock-based compensation expense in selling and administrative expenses. Software Development Costs The Company capitalizes qualifying internal payroll and external contracting and consulting costs related to the development of internal use software that are incurred during the application development stage, which includes design of the software configuration and interfaces, coding, installation, and testing. Costs incurred during the preliminary project along with post-implementation stages of internal use software are expensed as incurred. During the years ended December 31, 2019 and 2018 , the Company capitalized $0.2 million and $0.3 million , respectively, of qualifying internal payroll costs. The Company amortizes such costs over the estimated useful life of the software, which is three to five years once the software is placed in service. Other Operating Costs Other operating costs include travel, accounting/legal/consulting fees, credit card processing fees, banking fees, off-site storage fees, utilities, and other miscellaneous operating expenses. Income Taxes The Company determines the provision for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years 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 rates is recognized as income in the period that includes the enactment date. 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 criterion for recognition. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being recognized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company recognizes both interest and penalties related to uncertain tax positions as part of the income tax provision. Comprehensive Income and Accumulated Other 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 includes all changes in equity during a period except those resulting from investments by owners and distributions to owners. The Company’s comprehensive income consists of the Company’s net income, foreign currency translation adjustments from its Japan, Republic of Korea, Taiwan, Denmark, Norway, Sweden, Colombia, Mexico and China operations, remeasurement of intercompany balances classified as equity from its Taiwan, Mexico and Cyprus operations, and changes in the pension obligation for its Japanese employees. Concentration Risk A significant portion of our revenue is derived from our Ambrotose Life ® , Advanced Ambrotose ® , TruHealth ™ , Manapol ® Powder, and GI-Pro products. A decline in sales value of such products could have a material adverse effect on our earnings, cash flows, and financial position. Revenue from these products were as follows for the years ended December 31, 2019 and 2018 ( in thousands, except percentages ): 2019 2018 Sales by % of total Sales by % of total Ambrotose Life ® $ 34,975 22.2 % $ 18,824 10.9 % Advanced Ambrotose ® 22,390 14.2 % 44,054 25.4 % TruHealth ™ 16,193 10.3 % 17,537 10.1 % Manapol ® Powder 8,793 5.6 % 8,636 5.0 % GI-Pro Balance 6,559 4.2 % 7,187 4.2 % Total $ 88,910 56.5 % $ 96,238 55.6 % Our business is not currently exposed to customer concentration risk given that no independent associate has ever accounted for more than 10% of our consolidated net sales. The Company maintains supply agreements with its suppliers and manufacturers. Some of the supply agreements contain exclusivity clauses and/or minimum annual purchase requirements. Failure to satisfy minimum purchase requirements could result in the loss of exclusivity. During the year ended December 31, 2019 , the Company purchased finished goods from four suppliers that accounted for 56.0% of the year's cost of sales. During the year ended December 31, 2018 , the Company purchased finished goods from two suppliers that accounted for 72.4% of the year's cost of sales. The Company maintains other supply and manufacturing agreements to minimize exposure to supplier risk. Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash and cash equivalents, investments, receivables, and restricted cash. The Company utilizes financial institutions that the Company considers to be of high credit quality and periodically evaluates the credit rating of such institutions and the allocation of their investments to minimize exposure to credit concentration risk. Fair Value of Financial Instruments The fair value of the Company’s financial instruments, including cash and cash equivalents, restricted cash, time deposits, money market investments, receivables, payables, and accrued expenses, approximate their carrying values due to their relatively short maturities. See Note 2 to our Consolidated Financial Statements, Fair Value , for more information. Recently Adopted Accounting Pronouncements The Company adopted Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842) ( "ASU 2016-02" ) as of January 1, 2019 and applied it on a modified retrospective basis approach and elected to not adjust periods prior to January 1, 2019. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which, among other things, allowed the carry forward of the historical lease classification. This new standard requires companies to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. The adoption increased assets, net of incentive, by $4.7 million and liabilities by $6.1 million on our consolidated balance sheets and did not have a significant impact on our consolidated statement of operations and statements of cash flows. These leases primarily relate to office buildings and office equipment. See Note 8, Leases for more information. In February 2018, the Financial Accounting Standards Board ("FASB") issued ASU 2018-02, Income Statement - Reporting Comprehensive Income, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220) ("ASU 2018-02") , which amended its standard on comprehensive income to provide an option for an entity to reclassify the stranded tax effects of the Tax Cuts and Jobs Act (the "TCJA") that was passed in December of 2017 from accumulated other comprehensive income directly to retained earnings. The stranded tax effects result from the remeasurement of deferred tax assets and liabilities which were originally recorded in comprehensive income but whose remeasurement is reflected in the income statement. This is a one-time amendment applicable only to the changes resulting from the TCJA. The Company adopted this standard on January 1, 2019. The overall financial impact of adopting this standard did not have a material effect on our consolidated financial statements. Accounting Pronouncements Issued But Not Yet Effective In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13") . This standard adds to U.S. GAAP an impairment model (known as the current expected credit loss ("CECL") model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which is intended to result in the more timely recognition of losses. Under the CECL model, entities will estimate credit losses over the entire contractual term of

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE The Company utilizes fair value measurements to record fair value adjustments to certain financial assets and to determine fair value disclosures. Fair Value Measurements (Topic 820) of the FASB establishes a fair value hierarchy that requires the use of observable market data, when available, and prioritizes the inputs to valuation techniques used to measure fair value in the following categories: • Level 1—Quoted unadjusted prices for identical instruments in active markets. • Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all observable inputs and significant value drivers are observable in active markets. • Level 3—Model derived valuations in which one or more significant inputs or significant value drivers are unobservable, including assumptions developed by the Company. The primary objective of the Company’s investment activities is to preserve principal while maximizing yields without significantly increasing risk. The investment instruments held by the Company are interest bearing deposits for which quoted market prices are readily available. The Company considers these highly liquid investments to be cash equivalents. These investments are classified within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets. The tables below present the recorded amount of financial assets measured at fair value, which approximately equates to the carrying value due to the relatively short maturities of these respective assets, (in thousands) on a recurring basis as of December 31, 2019 and 2018 .

Leases [Abstract]
Leases of Lessee Disclosure [Text Block]	LEASES Adoption of ASC Topic 842, Leases On January 1, 2019, the Company adopted ASC Topic 842, Leases, ("ASC Topic 842") using the modified retrospective approach using the effective date method, which was applied to historical leases that were still effective as of January 1, 2019. Results for reporting periods beginning January 1, 2019, are presented in accordance with ASC Topic 842, while prior period amounts are reported in accordance with historical accounting treatment under ASC Topic 840, Leases, ("ASC Topic 840"). In accordance with the adoption of ASC Topic 842, the Company now records an operating lease right-of-use ("ROU") asset and operating lease liability on the Consolidated Balance Sheets for all operating leases with a contract term in excess of 12 months. Prior to the adoption of ASC Topic 842, these same leases were treated as operating leases under ASC Topic 840 and therefore were not recorded on the December 31, 2018 Consolidated Balance Sheet. There was no impact to retained earnings and no significant impact on the Consolidated Statements of Operations or the Consolidated Statements of Cash Flows as a result of adopting ASC Topic 842. Lease Recognition The Company has entered into contractual lease arrangements to rent office space and other office equipment from third-party lessors. If a contract conveys the right to control the use of identified PP&E (an identified asset) for a period of time in exchange for consideration, the Company considers the contract to be a lease, or to contain a lease, in accordance with ASC Topic 842. Right of use (ROU) assets represent Mannatech’s right to use an underlying asset for the lease term, and lease liabilities represent Mannatech’s obligation to make future lease payments arising from the lease. Operating lease liabilities and financing lease liabilities are recorded at the present value of lease payments over the lease term at the commencement date. The related ROU assets are recorded on the same date at the amount of the initial liability, adjusted for incentives received, prepayments made to the lessor, and any initial direct costs incurred, as applicable. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company recognizes lease expense for these short-term leases on a straight-line basis over the lease term. The Company accounts for lease components, such as office space, separately from the non-lease components, such as maintenance service fees, based on estimated costs from the vendor. Mannatech uses the implicit interest rate when readily determinable; however, most of Mannatech's lease agreements do not provide an implicit interest rate. As such, the Company determines the present value of future lease payments using the incremental borrowing rate available at the commencement date of the contract, or as of January 1, 2019 in the case of existing leases at adoption of ASC 842. The incremental borrowing rate is the rate available to the Company for a fully collateralized, fully amortizing loan, with the same term as the lease. The operating lease ROU asset also includes any lease incentives received in the recognition of the present value of future lease payments. Certain of Mannatech's leases may also include escalation clauses or options to extend or terminate the lease. These options are included in the present value recorded for the leases when it is reasonably certain that Mannatech will exercise that option. None of Mannatech’s current leases contain guarantees of residual value. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Lease costs represent the straight-line lease expense of ROU assets and short-term leases. Mannatech determines if an arrangement is a lease at inception of the contract. Resulting operating lease assets are recorded on the Consolidated Balance Sheets as a component of "Other assets" with offsetting liabilities recorded as a component of "Accrued expenses" and "Other long-term liabilities". Finance lease assets are recorded on the Consolidated Balance Sheets as a component of “Property and equipment, net” with related liabilities recorded as “Current portion of finance leases” or as “Finance leases, excluding current portion”. As of December 31, 2019 , Mannatech has six financing leases, all of which pertain to certain equipment used in the business. In general, Mannatech’s operating leases relate to office space used in Mannatech’s operations, including its headquarters in Flower Mound, Texas, as well as office space in other locations around the globe in which the Company does business. As of December 31, 2019 , our leased assets and liabilities consisted of the following (in thousands): Leases Classification December 31, 2019 Assets ROU Assets from operating leases Other assets $ 5,568 ROU Assets from financing leases Property and equipment, net 269 Total leased assets 5,837 Liabilities Current Operating Accrued expenses $ 1,622 Financing Current portion of finance leases 87 Long-Term Operating Other long-term liabilities 5,307 Financing Finance leases, excluding current portion 176 Total leased liabilities $ 7,192 We incurred the following lease costs related to our operating and finance leases (in thousands): Lease Cost Classification Twelve Months Ended December 31, 2019 Operating lease cost Other operating cost $ 2,074 Finance lease cost Amortization of leased assets Depreciation and amortization 111 Interest on lease liabilities Interest expense 17 Total lease cost $ 2,202 For the twelve months ended December 31, 2019 , cash paid amounts included in the measurement of lease liabilities included (in thousands): Lease Payments Twelve Months Ended December 31, 2019 Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from operating leases $ 2,154 Financing cash flows from finance leases 222 Lease term and discount rates related to the Company's leases are as follows: December 31, 2019 Operating leases Weighted-average remaining lease term (years) 6.1 Weighted-average discount rate 4.04 % Financing leases Weighted-average remaining lease term (years) 3.2 Weighted-average discount rate 4.95 % As of December 31, 2019 , future minimum lease payments on operating and financing leases were as follows (in thousands): December 31, 2019 Maturity of lease liabilities Operating Leases Financing Leases 2020 $ 1,884 $ 104 2021 1,592 90 2022 1,163 64 2023 605 36 Thereafter 2,752 10 Total future minimum lease payments $ 7,996 $ 304 Imputed interest (1,067 ) (41 ) Present value of minimum lease payments $ 6,929 $ 263 Under ASC Topic 840 future minimum lease payments for non-cancelable leases existing at December 31, 2018 were as follows (in thousands): December 31, 2018 Maturity of lease liabilities Operating Leases Capital Leases 2019 $ 1,850 $ 81 2020 977 40 2021 583 28 2022 586 7 2023 586 — Thereafter 2,737 — Total of future minimum lease payments at December 31, 2018 $ 7,319 $ 156 Less: Amounts representing interest (effective interest rate 5.61%) — (9 ) Present Value of lease obligations as of December 31, 2018 $ 7,319 $ 147

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

In addition to net operating loss attributes, the Company has recorded a foreign tax credit carryforward of $ 4.2 million , which will begin to expire in 2025 and a charitable contribution carryforward of $0.1 million , which will expire between 2019-2023. The Company maintains a full valuation against both the foreign tax credits and the charitable contribution carryforward. At December 31, 2019 and 2018 , the Company’s valuation allowance was $12.4 million and $12.8 million , respectively. The provisions of ASC Topic 740 require a company to record a valuation allowance when the “more likely than not” criterion for realizing a deferred tax asset cannot be met. A company is to use judgment in reviewing both positive and negative evidence of realizing a deferred tax asset. Furthermore, the weight given to the potential effect of such evidence is commensurate with the extent the evidence can be objectively verified. The valuation allowances presented below (in millions) at December 31, 2019 and 2018 , represented a reserve against the Company’s net deferred tax asset the Company believed the “more likely than not ” criterion for recognition purposes could not be met. The U.S. valuation allowance decreased due to the utilization of net operating losses in the current year.

Topic 740 requires that a company recognize in its financial statements the impact of tax positions that meet a “more likely than not” threshold, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. As of December 31, 2019 , the Company recorded $0.2 million in other long-term liabilities related to uncertain income tax positions and income tax reserves associated with various audits. At December 31, 2019 , the Company had unrecognized tax benefits of $0.2 million that, if recognized, would impact the effective tax rate. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows, for the years ended December 31, 2019 and 2018 (in thousands): 2019 2018 Balance as of January 1 $ 79 $ 79 Additions for tax positions related to the current year — — Additions for tax positions of prior years — — Reductions of tax positions of prior years — — Settlements — — Balance as of December 31 $ 79 $ 79 The Company recognizes interest and/or penalties related to uncertain tax positions in current income tax expense.

Although it is not reasonably possible to estimate the amount by which unrecognized tax benefits may increase or decrease within the next twelve months due to uncertainties regarding the timing of any examinations, the Company does not expect its unrecognized tax benefits to decrease during the next twelve months. The Company files income tax returns in the United States federal jurisdiction and various state and foreign jurisdictions. As of December 31, 2019, the tax years that remained subject to examination by a major tax jurisdiction for the Company’s most significant subsidiaries were as follows: Jurisdiction Open Years Australia 2012-2018 Japan 2015-2018 Republic of Korea 2015-2018 Switzerland 2015-2018 United States 2016-2018

The 2017 Plan supersedes the Mannatech, Incorporated 2008 Stock Incentive Plan, as amended, which was set to expire on February 20, 2018 . The Board has reserved a maximum of 370,000 shares of our common stock that may be issued under the 2017 Plan (subject to adjustments for stock splits, stock dividends or other changes in corporate capitalization). As of December 31, 2019 , the Company had a total of 162,767 shares available for grant under the 2017 Plan, which expires on April 16, 2027 . The 2017 Plan provides for grants of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance stock and performance stock units to our employees, board members, and consultants. However, only employees of the Company and its corporate subsidiaries are eligible to receive incentive stock options. The exercise price per share for all stock options will be no less than the market value of a share of common stock on the date of grant. Any incentive stock option granted to an employee owning more than 10% of our common stock will have an exercise price of no less than 110% of our common stock’s market value on the grant date. The majority of stock options vest over two or three years, and generally are granted with a term of ten years, or five years in the case of an incentive option granted to an employee who owns more than 10% of our common stock. A summary of changes in stock options outstanding during the year ended December 31, 2019 , is as follows: 2019 Number of Options (in thousands) Weighted average exercise price Weighted average remaining contractual life (in years) Aggregate intrinsic value (in thousands) Outstanding at beginning of year 421 $ 16.68 Granted 15 16.68 Exercised (2 ) 5.72 Expired (28 ) 23.88 Forfeit (25 ) 16.37 Outstanding at end of year 381 $ 16.24 4.97 $ — Options exercisable at year end 326 $ 16.25 5.48 $ — During 2019 , the Company issued 1,667 new shares upon the exercise of options and granted 15,000 new options to management and members of the Board. Options exercised during the year ending December 31, 2019 and December 31, 2018 had a total intrinsic value, calculated as the difference between the exercise date stock price and the exercise price of less than $0.1 million . Non-vested shares at December 31, 2019 and 2018 were approximately 55,335 and 126,000 , respectively. Valuation and Expense Information Under FASB ASC Topic 718 Compensation – Stock Compensation The Company is required to measure and recognize compensation expense related to any outstanding and unvested stock options previously granted, and thereafter recognize, in its consolidated financial statements, compensation expense related to any new stock options granted after implementation using a calculated fair-value based option-pricing model. The Company uses the Black-Scholes option-pricing model to calculate the fair value of all of its stock options and its assumptions are based on historical information. The following assumptions were used to calculate the compensation expense and the calculated fair value of stock options granted each year: 2019 2018 Dividend yield: 7.5 % 2.4-2.9 % Risk-free interest rate: 1.9 % 2.5-2.8 % Expected market price volatility: 47.6 % 55.6-56.4 % Average expected life of stock options: 4.5 years 4.5 years The computation of the expected volatility assumption used in the Black-Scholes calculations for new grants is based on historical volatilities of the Company’s stock. The expected life assumptions are based on the Company’s historical employee exercise and forfeiture behavior. The weighted-average grant-date fair value of stock options granted during the years ended December 31, 2019 and 2018 was $3.72 and $7.29 per share, respectively. The total fair value of awards vested during the years ended December 31, 2019 and 2018 was $0.4 million and $0.6 million , respectively. The Company recorded the following amounts related to the expense of the fair values of options and restricted share awards during the years ended December 31, 2019 and 2018 (in thousands) : 2019 2018 Selling, general and administrative expenses and income from operations before income taxes $ 456 $ 888 Benefit for income taxes (23 ) (50 ) Effect on net income $ 433 $ 838 As of December 31, 2019 , the Company had approximately $0.2 million of total unrecognized compensation expense related to stock options and restricted share awards currently outstanding, to be recognized in future years, ending December 31, as follows (in thousands): Total gross unrecognized compensation expense Total tax benefit associated with unrecognized compensation expense Total net unrecognized compensation expense 2020 $ 136 $ 11 $ 125 2021 15 3 12 $ 151 $ 14 $ 137

It is not possible at this time to predict whether the Company will incur any liability, or to estimate the ranges of damages, if any, which may be incurred in connection with this matter. However, the Company believes it has a valid defense and will vigorously defend this claim. This matter remains open. Litigation in General The Company has incurred several claims in the normal course of business. The Company believes such claims can be resolved without any material adverse effect on its consolidated financial position, results of operations, or cash flows. The Company maintains certain liability insurance; however, certain costs of defending lawsuits are not covered by or only partially covered by its insurance policies, including claims that are below insurance deductibles. Additionally, insurance carriers could refuse to cover certain claims, in whole or in part. The Company accrues costs to defend itself from litigation as they are incurred. The outcome of litigation is uncertain, and despite management’s views of the merits of any litigation, or the reasonableness of the Company’s estimates and reserves, the Company’s financial statements could nonetheless be materially affected by an adverse judgment. The Company believes it has adequately reserved for the contingencies arising from current legal matters where an outcome was deemed to be probable, and the loss amount could be reasonably estimated.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE The Company calculates basic Earnings per Share ("EPS") by dividing net income (loss) by the weighted-average number of common shares outstanding for the period. Diluted EPS also reflects the potential dilution that could occur if common stock were issued for awards outstanding under the Mannatech, Incorporated 2017 Stock Incentive Plan. In determining the potential dilution effect of outstanding stock options during 2019, the Company used the average common stock close price of $17.11 per share. For the year ended December 31, 2019, there were 2.39 million weighted-average common shares outstanding used for the basic EPS calculation. Approximately 0 .05 million shares subject to options were included in the calculation resulting in 2.44 million dilutive shares used to calculate diluted EPS. For the year ended December 31, 2019, approximately 1.0 million of the Company's stock options were excluded from the diluted EPS calculation as the effect would have been antidilutive. For the year ended December 31, 2018, shares of the Company's stock subject to options were excluded from the diluted EPS calculation as their effect would have been antidilutive. The Company reported a net loss for the year ended December 31, 2018.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company's sole reporting segment is one where we sell proprietary nutritional supplements, skin care and anti-aging products, and weight-management and fitness products through network marketing distribution channels operating in twenty-five countries. Each of the business units sells similar packs (with the exception of the United States, Canada, South Africa, Japan, Australia, New Zealand, Singapore, Hong Kong, and Taiwan where packs have been replaced with associate fees, see Note 1 Organization and Summary of Significant Accounting Policies ) and products and possesses similar economic characteristics, such as selling prices and gross margins. In each country, the Company markets its products and pays commissions and incentives in similar market environments. The Company’s management reviews its financial information by country and focuses its internal reporting and analysis of revenues by packs and product sales. The Company sells its products through its independent associates who occupy positions in our network and distribute products through similar distribution channels in each country. No single independent associate has ever accounted for more than 10% of the Company’s consolidated net sales. The Company also operates a non-direct selling business in mainland China. Our subsidiary in China, Meitai, is operating as a traditional retailer under a cross-border e-commerce model. Meitai cannot legally conduct a direct selling business in China unless it acquires a direct selling license in China. The Company operates facilities in thirteen countries and sells product in twenty-six countries around the world. These facilities are located in the United States, Canada, Australia, the United Kingdom, Japan, the Republic of Korea (South Korea), Taiwan, South Africa, Mexico, Hong Kong, Singapore, Colombia and China. Each facility services different geographic areas. We currently sell our products in three regions: (i) the Americas (the United States, Canada, Colombia and Mexico); (ii) EMEA (Austria, the Czech Republic, Denmark, Estonia, Finland, Germany, the Republic of Ireland, Namibia, the Netherlands, Norway, South Africa, Spain, Sweden and the United Kingdom); (iii) Asia/Pacific (Australia, Japan, New Zealand, the Republic of Korea, Singapore, Taiwan, Hong Kong and China).

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements and footnotes include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the Company’s consolidated financial statements in accordance with generally accepted accounting principles requires the use of estimates that affect the reported value of assets, liabilities, revenues and expenses. These estimates are based on historical experience and various other factors. The Company continually evaluates the information used to make these estimates as the business and economic environment changes. Historically, actual results have not varied materially from the Company’s estimates and the Company does not currently anticipate a significant change in its assumptions related to these estimates. However, actual results may differ from these estimates under different assumptions or conditions. The use of estimates is pervasive throughout the consolidated financial statements, but the accounting policies and estimates considered the most significant are described in this note to the consolidated financial statements, Organization and Summary of Significant Accounting Policies .
Foreign Currency Translation	Foreign Currency Translation The United States dollar is the functional currency for the majority of the Company’s foreign subsidiaries. As a result, nonmonetary assets and liabilities are remeasured at their approximate historical rates, monetary assets and liabilities are remeasured at exchange rates in effect at the end of the year, and revenues and expenses are remeasured at weighted-average exchange rates for the year. The local currency is the functional currency of our subsidiaries in Columbia, Japan, Republic of Korea, Taiwan, Norway, Denmark, Sweden, Mexico and China. These subsidiaries’ assets and liabilities are translated into United States dollars at exchange rates existing at the balance sheet dates, revenues and expenses are translated at weighted-average exchange rates, and shareholders’ equity and intercompany balances are translated at historical exchange rates. The foreign currency translation adjustment is recorded as a separate component of shareholders’ equity and is included in accumulated other comprehensive income. Transaction losses totaled approximately $0.7 million for the year ended December 31, 2019 and transaction gains totaled approximately $0.3 million for the year ended December 31, 2018 , and are included in other expense, net in the Company’s consolidated statements of operations.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company includes in its cash and cash equivalents credit card receivables due from its credit card processor, as the cash proceeds from credit card receivables are received within 24 to 72 hours. As of December 31, 2019 and 2018 , credit card receivables were $0.7 million and $1.6 million , respectively, and cash and cash equivalents held in bank accounts in foreign countries totaled $18.2 million and $19.9 million , respectively. The Company invests cash in liquid instruments, such as money market funds and interest bearing deposits. The Company also holds cash in high quality financial institutions and does not believe it has an excessive exposure to credit concentration risk. At December 31, 2019, a portion of our cash and cash equivalent balances were concentrated within the Republic of South Korea, with total net assets within this foreign location totaling $19.2 million . In addition, for the year ended December 31, 2019, a concentrated portion of our operating cash flows were earned from operations within the Republic of South Korea. An adverse change in economic conditions within the Republic of South Korea could negatively affect the Company’s results of operations.
Restricted Cash	Restricted Cash The Company is required to restrict cash for: (i) direct selling insurance premiums and credit card sales in the Republic of Korea; (ii) reserve on credit card sales in the United States and Canada; and (iii) Australia building lease collateral. As of December 31, 2019 and 2018 , our total restricted cash was $6.2 million and $8.7 million , respectively. The Company classifies the restricted cash held in Korea and Australia as long-term since it relates to assets and services contracted for longer than one year.
Accounts Receivable	Accounts Receivable Accounts receivable are carried at their estimated collectible amounts. Receivables are created upon shipment of an order if the credit card payment is rejected or does not match the order total. As of December 31, 2019 and 2018 , receivables consisted primarily of amounts due from preferred customers and associates. The Company periodically evaluates its receivables for collectability based on historical experience, recent account activities, and the length of time receivables are past due and writes-off receivables when they become uncollectible. As of December 31, 2019 and 2018 , the Company held an allowance for doubtful accounts of $0.7 million and $0.8 million , respectively.
Inventories	Inventories Inventories consist of raw materials, finished goods, and promotional materials that are stated at the lower of cost (using standard costs that approximate average costs) or net realizable value. The Company periodically reviews inventories for obsolescence and any inventories identified as obsolete are reserved or written off.
Prepaid Expense and Other Current Assets [Policy Text Block]	Prepaid Expenses and Other Current Assets Prepaid expenses and other current assets were $2.2 million and $3.4 million at December 31, 2019 and 2018 , respectively. Included in the December 31, 2019 and 2018 balances were $0.8 million and $1.0 million in other prepaid assets, respectively. Also included in the balances at December 31, 2019 and 2018 were $0.7 million and $1.8 million for other prepaid deposits, respectively. At December 31, 2019 the balance in prepaid inventory was $0.7 million .
Property and Equipment	Property and Equipment Property and equipment are stated at cost, less accumulated depreciation and amortization computed using the straight-line method over the estimated useful life of each asset. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the improvements. Expenditures for maintenance and repairs are charged to expense as incurred. The cost of property and equipment sold or otherwise retired and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in other operating costs in the accompanying consolidated statements of operations. The estimated useful lives of fixed assets are as follows: Estimated useful life Office furniture and equipment 5 to 7 years Computer hardware and software 3 to 5 years Automobiles 3 to 5 years Leasehold improvements (1) 2 to 10 years (1) The Company amortizes leasehold improvements over the shorter of the useful estimated life of the leased asset or the lease term. Property and equipment are reviewed for impairment whenever an event or change in circumstances indicates that the carrying amount of an asset or group of assets may not be recoverable. The impairment review includes a comparison of future projected cash flows generated by the asset or group of assets with its associated net carrying value. If the net carrying value of the asset or group of assets exceeds expected cash flows (undiscounted and without interest charges), an impairment loss is recognized to the extent the carrying amount of the asset exceeds its fair value.
Other Assets	Other Assets At December 31, 2019 and 2018 , other assets were $9.6 million and $3.9 million , respectively. Included in the December 31, 2019 and 2018 balances were deposits for building leases in various locations of $2.2 million and $2.0 million , respectively. Also included in the December 31, 2019 and 2018 balances were $1.6 million and $1.7 million , respectively, representing a deposit with Mutual Aid Cooperative and Consumer in the Republic of Korea, an organization established by the Republic of Korea’s Fair Trade Commission’s approval to compensate and protect consumers who participate in network marketing activities from damages. Other assets at each of December 31, 2019 and 2018 also include $0.2 million of indefinite lived intangible assets relating to the Manapol ® powder trademark. The December 31, 2019 balance also includes $5.6 million of operating lease right-of-use assets. See Note 5, Leases for more information.
Notes Payable	Notes Payable Notes payable were $1.1 million and $1.6 million as of December 31, 2019 and December 31, 2018 , respectively, as a result of funding from a capital financing agreement related to our investment in leasehold improvements, computer hardware and software and other financing arrangements. Payments are made monthly according to the terms of the agreements which have a weighted average effective interest rate of 5.8% and are collateralized by leasehold improvements and computer hardware and software. At December 31, 2019 , the current portion was $0.7 million and the long-term portion was $0.4 million . At December 31, 2018 , the current portion was $0.7 million and the long-term portion was $0.9 million .
Other Long-Term Liabilities	Other Long-Term Liabilities Other long-term liabilities were $6.2 million and $2.3 million for the years ending December 31, 2019 and 2018 , respectively. At December 31, 2018, we recorded $ 1.3 million of lease incentive obligation for leasehold improvements at our corporate headquarters. At each of December 31, 2019 and 2018 , we recorded $0.2 million , respectively, in other long-term liabilities related to uncertain income tax positions (see Note 7, Income Taxes ). Certain operating leases for the Company’s regional office facilities contain a restoration clause that requires the Company to restore the premises to its original condition. At December 31, 2019 and 2018 , accrued restoration costs related to these leases amounted to $0.3 million and $0.4 million , respectively. At December 31, 2019 and 2018 , government mandated severance accruals in certain international offices amounted to $0.4 million and $0.3 million , respectively. The Company also recorded a long-term liability for an estimated defined benefit obligation related to a non-U.S. defined benefit plan for its Japan operations of $0.3 million and $0.4 million as of December 31, 2019 and 2018 , respectively (See Note 9, Employee Benefit Plans ). The December 31, 2019 balance also includes $5.3 million of long-term operating lease right-of-use obligations. See Note 5, Leases for more information.
Revenue Recognition and Deferred Commissions		Revenue Recognition The Company’s revenue is derived from sales of individual products and associate fees or, in certain geographic markets, starter and renewal packs. Substantially all of the Company’s product sales are made at published wholesale prices to associates and preferred customers. The Company records revenue net of any sales taxes and records a reserve for expected sales returns based on its historical experience. The Company recognizes revenue from shipped products when control of the product transfers to the customer, thus the performance obligation is satisfied. Corporate-sponsored event revenue is recognized when the event is held. Orders placed by associates or preferred customers constitute our contracts. Product sales placed in the form of an automatic order contain two performance obligations - a) the sale of the product and b) the loyalty program. For these contracts, the Company accounts for each of these obligations separately as they are each distinct. The transaction price is allocated between the product sale and the loyalty program on a relative standalone selling price basis. Sales placed through a one-time order contain only the first performance obligation noted above - the sale of the product. The Company provides associates with access to a complimentary three-month package for the Success Tracker TM and Mannatech+ online business tools with the first payment of an associate fee. The first payment of an associate fee contains three performance obligations a) the associate fee, whereby the Company provides an associate with the right to earn commissions, bonuses and incentives for a year, b) three months of complimentary access to utilize the Success Tracker™ online tool and c) three months of complimentary access to utilize the Mannatech+ online business tool. The transaction price is allocated between the three performance obligations on a relative standalone selling price basis. Associates do not have complimentary access to online business tools after the first contractual period. With regard to both of the aforementioned contracts, the Company determines the standalone selling prices based on our overall pricing objectives, taking into consideration market conditions and other factors, including the value of the contracts. Our sales mix for the years ended December 31, was as follows (in millions, except percentages) : 2019 Percentage 2018 Percentage Consolidated product sales $ 154.6 98.0 % $ 170.2 98.0 % Consolidated pack sales and associate fees (a) 2.3 1.5 % 2.5 1.5 % Consolidated other 0.8 0.5 % 0.9 0.5 % Total consolidated net sales $ 157.7 100.0 % $ 173.6 100.0 % Revenues by reporting segment are presented in Note 15 of our consolidated financial statements. We believe that the disaggregation of our revenues as reflected above, coupled with further discussion below, and the reporting segment in Note 15, depicts how the nature, amount, timing and uncertainty of our revenues and cash flows are affected by economic factors. Deferred Commissions The Company defers commissions on (i) the sales of products shipped but not received by customers by the end of the respective period and (ii) the loyalty program. Deferred commissions are incremental costs and are amortized to expense consistent with how the related revenue is recognized. Deferred commissions were $1.8 million and $2.4 million at December 31, 2019 and December 31, 2018 , respectively. The full $2.4 million balance at December 31, 2018 was amortized to commissions expense for the twelve months ended December 31, 2019 . Deferred Revenue The Company defers certain components of its revenue. Deferred revenue consisted of: (i) sales of products shipped but not received by the customers by the end of the respective period; (ii) revenue from the loyalty program; (iii) prepaid registration fees from customers planning to attend a future corporate-sponsored event; and (iv) prepaid annual associate fees. At December 31, 2019 and December 31, 2018 , the Company’s deferred revenue was $4.4 million and $5.3 million , respectively. The full $5.3 million balance at December 31, 2018 was recognized as revenue for the twelve months ended December 31, 2019 . The Company's customer loyalty program conveys a material right to the customer as it provides the promise to redeem loyalty points for the purchase of products, which is based on earning points through placing consecutive qualified automatic orders. The Company factors in breakage rates, which is the percentage of the loyalty points that are expected to be forfeited or expire, for purposes of revenue recognition. Breakage rates are estimated based on historical data and can be reasonably and objectively determined. The deferred revenue associated with the loyalty program at December 31, 2019 and December 31, 2018 was $3.1 million and $4.2 million , as follows: Loyalty program (in thousands) Loyalty deferred revenue as of January 1, 2018 $ 6,406 Loyalty points forfeited or expired (4,332 ) Loyalty points used (11,398 ) Loyalty points vested 12,469 Loyalty points unvested 1,086 Loyalty deferred revenue as of December 31, 2018 $ 4,231 Loyalty deferred revenue as of January 1, 2019 $ 4,231 Loyalty points forfeited or expired (4,348 ) Loyalty points used (9,127 ) Loyalty points vested 11,320 Loyalty points unvested 1,051 Loyalty deferred revenue as of December 31, 2019 $ 3,127 Sales Refund and Allowances The Company utilizes the expected value method to estimate the sales returns and allowance liability by taking the weighted average of the sales return rates over a rolling six-month period. The Company allocates the total amount recorded within the sales return and allowance liability as a reduction of the overall transaction price for the Company’s product sales. The Company deems the sales refund and allowance liability to be a variable consideration. Historically, our sales returns have not materially changed through the years, as the majority of our customers who return their merchandise do so within the first 90 days after the original sale. Sales returns have historically averaged 1.5% or less of our gross sales. For the years ended December 31, 2019 and December 31, 2018 , our sales return reserve consisted of the following (in thousands) : Sales reserve as of January 1, 2018 $ 117 Provision related to sales made in current period 1,198 Adjustment related to sales made in prior periods (10 ) Actual returns or credits related to current period (1,125 ) Actual returns or credits related to prior periods (104 ) Sales reserve as of December 31, 2018 $ 76 Sales reserve as of January 1, 2019 $ 76 Provision related to sales made in current period 1,037 Adjustment related to sales made in prior periods 31 Actual returns or credits related to current period (973 ) Actual returns or credits related to prior periods (103 ) Sales reserve as of December 31, 2019 $ 68
Shipping and Handling Costs	Shipping and Handling Costs The Company records inbound freight as a component of inventory and cost of sales. The Company records freight and shipping fees collected from its customers as fulfillment costs. Freight and shipping fees are not deemed to be separate performance obligations as these activities occur before the customer receives the product.
Commission and Incentive Expenses	Commission and Incentive Expenses Associates earn commissions and incentives based on their direct and indirect commissionable net sales over each month of the fiscal year. The Company accrues commissions and incentives when earned by associates and pays commissions on product and pack sales on a monthly basis.
Advertising Expenses	Advertising Expenses The Company expenses advertising and promotions in selling and administrative expenses when incurred. Advertising and promotional expenses were approximately $3.5 million and $5.6 million for the years ended December 31, 2019 and 2018 , respectively.

Research and Development Expenses	Research and Development Expenses The Company expenses research and development expenses as incurred. Research and development expenses related to new product development, enhancement of existing products, clinical studies and trials, Food and Drug Administration compliance studies, general supplies, internal salaries, third-party contractors, and consulting fees were approximately $1.1 million and $1.0 million , respectively, for the years ended December 31, 2019 and 2018 . Salaries and contract labor are included in selling and administrative expenses and all other research and development costs are included in other operating costs.
Stock-Based Compensation	Stock-Based Compensation The Company currently has one active stock-based compensation plan, the Mannatech, Incorporated 2017 Stock Incentive Plan, which was adopted by the Company’s Board of Directors (the "Board") on April 17, 2017 and was approved by its shareholders on June 8, 2017 , and subsequently amended by the Board at its February 2019 special meeting, which amendment was approved by the Company's shareholders on June 11, 2019 (as amended, the "2017 Plan"). The 2017 Plan supersedes the Mannatech, Incorporated 2008 Stock Incentive Plan (as amended the "2008 Plan"), which was set to expire on February 20, 2018 . The Board has reserved a maximum of 370,000 shares of our common stock that may be issued under the 2017 Plan (subject to adjustments for stock splits, stock dividends or other changes in corporate capitalization). The 2017 Plan provides for grants of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance stock and performance stock units to our employees, board members, and consultants. However, only employees of the Company and its corporate subsidiaries are eligible to receive incentive stock options. The exercise price per share for all stock options will be no less than the market value of a share of common stock on the date of grant. Any incentive stock option granted to an employee owning more than 10% of our common stock will have an exercise price of no less than 110% of our common stock’s market value on the grant date. The majority of stock options vest over two or three years, and generally are granted with a term of ten years, or five years in the case of an incentive option granted to an employee who owns more than 10% of our common stock. At date of grant, the Company determines the fair value of the stock option award and recognizes compensation expense over the requisite service period, or the vesting period of the award. The fair value of the stock option award is calculated using the Black-Scholes option-pricing model. The Company records stock-based compensation expense in selling and administrative expenses.
Software Development Costs	Software Development Costs The Company capitalizes qualifying internal payroll and external contracting and consulting costs related to the development of internal use software that are incurred during the application development stage, which includes design of the software configuration and interfaces, coding, installation, and testing. Costs incurred during the preliminary project along with post-implementation stages of internal use software are expensed as incurred. During the years ended December 31, 2019 and 2018 , the Company capitalized $0.2 million and $0.3 million , respectively, of qualifying internal payroll costs. The Company amortizes such costs over the estimated useful life of the software, which is three to five years once the software is placed in service.
Other Operating Costs	Other Operating Costs Other operating costs include travel, accounting/legal/consulting fees, credit card processing fees, banking fees, off-site storage fees, utilities, and other miscellaneous operating expenses.
Income Taxes	Income Taxes The Company determines the provision for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years 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 rates is recognized as income in the period that includes the enactment date. 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 criterion for recognition. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being recognized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company recognizes both interest and penalties related to uncertain tax positions as part of the income tax provision.
Comprehensive Income and Accumulated Other Comprehensive Income	Comprehensive Income and Accumulated Other 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 includes all changes in equity during a period except those resulting from investments by owners and distributions to owners. The Company’s comprehensive income consists of the Company’s net income, foreign currency translation adjustments from its Japan, Republic of Korea, Taiwan, Denmark, Norway, Sweden, Colombia, Mexico and China operations, remeasurement of intercompany balances classified as equity from its Taiwan, Mexico and Cyprus operations, and changes in the pension obligation for its Japanese employees.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration Risk A significant portion of our revenue is derived from our Ambrotose Life ® , Advanced Ambrotose ® , TruHealth ™ , Manapol ® Powder, and GI-Pro products. A decline in sales value of such products could have a material adverse effect on our earnings, cash flows, and financial position.
Concentration Risk	Concentration Risk A significant portion of our revenue is derived from our Ambrotose Life ® , Advanced Ambrotose ® , TruHealth ™ , Manapol ® Powder, and GI-Pro products. A decline in sales value of such products could have a material adverse effect on our earnings, cash flows, and financial position. Revenue from these products were as follows for the years ended December 31, 2019 and 2018 ( in thousands, except percentages ): 2019 2018 Sales by % of total Sales by % of total Ambrotose Life ® $ 34,975 22.2 % $ 18,824 10.9 % Advanced Ambrotose ® 22,390 14.2 % 44,054 25.4 % TruHealth ™ 16,193 10.3 % 17,537 10.1 % Manapol ® Powder 8,793 5.6 % 8,636 5.0 % GI-Pro Balance 6,559 4.2 % 7,187 4.2 % Total $ 88,910 56.5 % $ 96,238 55.6 % Our business is not currently exposed to customer concentration risk given that no independent associate has ever accounted for more than 10% of our consolidated net sales. The Company maintains supply agreements with its suppliers and manufacturers. Some of the supply agreements contain exclusivity clauses and/or minimum annual purchase requirements. Failure to satisfy minimum purchase requirements could result in the loss of exclusivity. During the year ended December 31, 2019 , the Company purchased finished goods from four suppliers that accounted for 56.0% of the year's cost of sales. During the year ended December 31, 2018 , the Company purchased finished goods from two suppliers that accounted for 72.4% of the year's cost of sales. The Company maintains other supply and manufacturing agreements to minimize exposure to supplier risk. Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash and cash equivalents, investments, receivables, and restricted cash. The Company utilizes financial institutions that the Company considers to be of high credit quality and periodically evaluates the credit rating of such institutions and the allocation of their investments to minimize exposure to credit concentration risk.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value of the Company’s financial instruments, including cash and cash equivalents, restricted cash, time deposits, money market investments, receivables, payables, and accrued expenses, approximate their carrying values due to their relatively short maturities. See Note 2 to our Consolidated Financial Statements, Fair Value , for more information.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements The Company adopted Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842) ( "ASU 2016-02" ) as of January 1, 2019 and applied it on a modified retrospective basis approach and elected to not adjust periods prior to January 1, 2019. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which, among other things, allowed the carry forward of the historical lease classification. This new standard requires companies to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. The adoption increased assets, net of incentive, by $4.7 million and liabilities by $6.1 million on our consolidated balance sheets and did not have a significant impact on our consolidated statement of operations and statements of cash flows. These leases primarily relate to office buildings and office equipment. See Note 8, Leases for more information. In February 2018, the Financial Accounting Standards Board ("FASB") issued ASU 2018-02, Income Statement - Reporting Comprehensive Income, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220) ("ASU 2018-02") , which amended its standard on comprehensive income to provide an option for an entity to reclassify the stranded tax effects of the Tax Cuts and Jobs Act (the "TCJA") that was passed in December of 2017 from accumulated other comprehensive income directly to retained earnings. The stranded tax effects result from the remeasurement of deferred tax assets and liabilities which were originally recorded in comprehensive income but whose remeasurement is reflected in the income statement. This is a one-time amendment applicable only to the changes resulting from the TCJA. The Company adopted this standard on January 1, 2019. The overall financial impact of adopting this standard did not have a material effect on our consolidated financial statements. Accounting Pronouncements Issued But Not Yet Effective In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13") . This standard adds to U.S. GAAP an impairment model (known as the current expected credit loss ("CECL") model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which is intended to result in the more timely recognition of losses. Under the CECL model, entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications) from the date of initial recognition of the financial instrument. Measurement of expected credit losses are to be based on relevant forecasts that affect collectability. The scope of financial assets within the CECL methodology is broad and includes trade receivables from certain revenue transactions and certain off-balance sheet credit exposures. Different components of the guidance require modified retrospective or prospective adoption. ASU 2019-10 deferred the effective date of ASU 2016-13 for all entities except SEC filers that are not smaller reporting companies. This standard will be effective for us as of January 1, 2023. While our review is ongoing, we believe ASU 2016-13 will only have applicability to our receivables from revenue transactions. Under ASC 606, revenue is recognized when, among other criteria, it is probable that the entity will collect the consideration to which it is entitled for goods or services transferred to a customer. At the point that trade receivables are recorded, they become subject to the CECL model and estimates of expected credit losses on trade receivables over their contractual life will be required to be recorded at inception based on historical information, current conditions, and reasonable and supportable forecasts. The Company is currently evaluating whether the new guidance will have an impact on our consolidated financial statements or existing internal controls. Other recently issued accounting pronouncements did not or are not believed by management to have a material impact on the Company's present or future financial statements.
Fair Value Measurement	Fair Value Measurements (Topic 820) of the FASB establishes a fair value hierarchy that requires the use of observable market data, when available, and prioritizes the inputs to valuation techniques used to measure fair value in the following categories: • Level 1—Quoted unadjusted prices for identical instruments in active markets. • Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all observable inputs and significant value drivers are observable in active markets. • Level 3—Model derived valuations in which one or more significant inputs or significant value drivers are unobservable, including assumptions developed by the Company.

Unrecognized tax benefits	Topic 740 prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements, uncertain tax positions that it has taken or expects to take on a tax return. Topic 740 requires that a company recognize in its financial statements the impact of tax positions that meet a “more likely than not” threshold, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement.
