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 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).

Active business building associates ("independent associates" or "associates" or "distributors") and 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.

In March 2020, the World Health Organization (“WHO”) declared the outbreak of COVID-19 as a pandemic, which has spread throughout our international regions and the United States. We closed some offices and have worked remotely.

The Company depends on an independent sales force of distributors to market and sell its products to consumers. Developments such as social distancing and shelter-in-place directives have impacted and may continue to impact their ability to engage with potential and existing customers. The adverse economic effects of COVID-19 may also materially decrease demand for the Company’s products based on changes in consumer behavior or the restrictions in place by governments trying to curb the outbreak. For example, the Company has rescheduled corporate sponsored events, and in some cases, our associates have canceled sales meetings.

For some products, the Company experienced shortages of raw materials, packaging supplies and ingredients. We have experienced challenges in getting these materials and ingredients to our contract manufacturers and finished products to our distribution centers resulting from reductions in global transportation capacity. Despite the impact on the global supply chain, the Company has overcome obstacles in shipping to our customers.

While the conditions described above are expected to be temporary, prolonged workforce disruptions, continued disruption in our supply chain and potential decreases in consumer demands negatively impacted our sales in fiscal year 2020 and may continue to negatively impact sales in fiscal year 2021 as well as the Company’s overall liquidity. We are actively monitoring the global situation with a focus on our financial condition, liquidity, operations, suppliers, industry, and workforce.

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 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 gains totaled approximately $1.1 million for the year ended December 31, 2020 and transaction losses totaled approximately $0.7 million for the year ended December 31, 2019, and are included in other income (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, 2020 and 2019, credit card receivables were $2.4 million and $0.7 million, respectively, and cash and cash equivalents held in bank accounts in foreign countries totaled $18.6 million and $18.2 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, 2020, 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 $21.0 million. In addition, for the year ended December 31, 2020, 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, 2020 and 2019, our total restricted cash was $5.3 million and $6.2 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 and 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, 2020		December 31, 2019
Cash and cash equivalents at beginning of period	$	24,762	$	21,845
Current restricted cash at beginning of period	943		1,514
Long-term restricted cash at beginning of period	5,295		7,225
Cash, cash equivalents, and restricted cash at beginning of period	$	31,000	$	30,584

Cash and cash equivalents at end of period	$	22,207	$	24,762
Current restricted cash at end of period	944		943
Long-term restricted cash at end of period	4,346		5,295
Cash, cash equivalents, and restricted cash at end of period	$	27,497	$	31,000

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, 2020 and 2019, 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, 2020 and 2019, the Company held an allowance for doubtful accounts of $0.8 million and $0.7 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 $3.0 million and $2.2 million at December 31, 2020 and 2019, respectively. Included in the December 31, 2020 and 2019 balances were $1.1 million and $0.8 million in other prepaid assets, respectively. Also included in the balances at December 31, 2020 and 2019 were $1.1 million and $0.7 million for other prepaid deposits, respectively. Also included in the balances at December 31, 2020 and 2019 were $0.8 million and $0.7 million in prepaid inventory, respectively.

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			2 to 10 years

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, 2020 and 2019, other assets were $12.0 million and $9.6 million, respectively. The December 31, 2020 and 2019 balances include operating lease right of use assets of $6.9 million and $5.6 million, respectively. See Note 5, Leases for more information. Included in each of the December 31, 2020 and 2019 balances were deposits for building leases in various locations of $2.2 million. Also included in the December 31, 2020 and 2019 balances were $2.6 million and $1.6 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, 2020 and 2019 also include $0.2 million of indefinite lived intangible assets relating to the Manapol® powder trademark.

Notes Payable

Notes payable were $0.6 million and $1.1 million as of December 31, 2020 and December 31, 2019, 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 6.0% and are collateralized by leasehold improvements and computer hardware and software. At December 31, 2020, the current portion was $0.6 million and the long-term portion was $0.0 million. At December 31, 2019, the current portion was $0.7 million and the long-term portion was $0.4 million.

On April 10, 2020, the Company received loan proceeds of $2.2 million (the “Loan”) under the Paycheck Protection Program (“PPP”). The PPP was established under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), enacted on March 27, 2020, and is administered by the U.S. Small Business Administration (the “SBA”). The Loan to the Company was made through JPMorgan Chase Bank, N. A., the Company’s existing banker (the “Lender”). At the time the Company applied for and received the Loan, the Company planned to use the Loan proceeds for covered payroll costs, rent and utilities in accordance with the relevant terms and conditions of the CARES Act. After the Company received the proceeds of the Loan, the SBA provided subsequent guidance interpreting the PPP. Based on such subsequent guidance, the Company made the determination to repay the Loan in full, which it did on April 30, 2020.

Other Long-Term Liabilities

Other long-term liabilities were $7.2 million and $6.2 million for the years ending December 31, 2020 and 2019, respectively. At December 31, 2020 and 2019, we recorded long-term lease liabilities related to operating leases of $6.1 million and $5.3 million, respectively. See Note 5, Leases for more information. At each of December 31, 2020 and 2019, 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 each of December 31, 2020 and 2019, accrued restoration costs related to these leases amounted to $0.3 million. At December 31, 2020 and 2019, government mandated severance accruals in certain international offices amounted to $0.5 million and $0.4 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 $0.4 million and $0.3 million as of December 31, 2020 and 2019, respectively (See Note 9, Employee Benefit Plans).

Revenue Recognition

The Company’s revenue is derived from sales of individual products and associate fees or, in certain geographic markets, starter 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 TrackerTM 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):


	2020		Percentage		2019		Percentage
Consolidated product sales	$	146.2	96.5	%	$	154.6	98.0	%
Consolidated pack sales and associate fees	4.2		2.8	%	2.3		1.5	%
Consolidated other	1.0		0.7	%	0.8		0.5	%

We believe that the disaggregation of our revenues as reflected above, coupled with further discussion below, and the reporting segment in Note 15, Segment Information 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 $2.3 million and $1.8 million at December 31, 2020 and December 31, 2019, respectively. The full $1.8 million balance at December 31, 2019 was amortized to commissions expense for the twelve months ended December 31, 2020.

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, 2020 and December 31, 2019, the Company’s deferred revenue was $5.5 million and $4.4 million, respectively. The full $4.4 million balance at December 31, 2019 was recognized as revenue for the twelve months ended December 31, 2020.

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, 2020 and December 31, 2019 was $4.5 million and $3.1 million, as follows:


Loyalty program	(in thousands)
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


Loyalty deferred revenue as of January 1, 2020	$	3,127
Loyalty points forfeited or expired	(3,249)
Loyalty points used	(9,385)
Loyalty points vested	12,771
Loyalty points unvested	1,223
Loyalty deferred revenue as of December 31, 2020	$	4,487

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, 2020 and December 31, 2019, our sales return reserve consisted of the following (in thousands):


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)

Adjustment related to sales made in prior periods	5
Actual returns or credits related to current period	(959)
Actual returns or credits related to prior periods	(71)
Sales reserve as of December 31, 2020	$	71

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 remained constant at $3.5 million for each of the years ended December 31, 2020 and 2019. 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 $0.8 million and $1.1 million, respectively, for the years ended December 31, 2020 and 2019. 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 the Company's 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, 2020 and 2019, the Company capitalized $0.3 million and $0.2 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®, TruHealth™, Advanced Ambrotose®, Optimal Support Packets, 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, 2020 and 2019 (in thousands, except percentages):


	2020				2019
	Sales by product		% of total net sales		Sales by product		% of total net sales
Ambrotose Life®	$	36,066	23.8	%	$	34,975	22.2	%
TruHealth™	16,263		10.7	%	16,193		14.2	%
Advanced Ambrotose®	14,662		9.7	%	22,390		10.3	%
Optimal Support Packets	7,996		5.3	%	4,110		2.6	%
GI-Pro (MicroBiome)	7,513		5.0	%	6,559		4.2	%
Total	$	82,500	54.5	%	$	84,227	53.5	%

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, 2020, the Company purchased finished goods from four suppliers that accounted for 56.8% of the year's cost of sales. 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. 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 a lease incentive, by $4.7 million and increased 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 5, 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 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 Topic 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

Fair Value Disclosures [Abstract]

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, 2020 and 2019. The Company did not have any material financial liabilities that were required to be measured at fair value on a recurring basis at December 31, 2020 and 2019.

Leases [Abstract]

Leases of Lessee Disclosure [Text Block]

LEASES

The Company leases office space and equipment from third-party lessors. On January 1, 2019, the Company adopted ASC Topic 842, Leases, ("Topic 842") and related disclosures. See note 5 to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2019. As of December 31, 2020, the Company had net operating lease right of use ("ROU") assets of $6.9 million and net finance lease right of use assets of $0.3 million. At December 31, 2020, our operating lease liabilities were $8.2 million and our finance lease liabilities were $0.2 million.

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. 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 lessor. ROU assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make future lease payments arising from the lease.

Operating lease liabilities and finance 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. The Company uses the discount rate implicit in the lease when it is readily determinable. When it is not readily available, the Company discounts future lease payments using the incremental borrowing rate available to the Company as of the commencement date of the contract, or as of January 1, 2019 in the case of existing leases at the 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.

Operating lease costs are recognized on a straight-line basis over the lease term. Finance lease costs are composed of the amortization of the ROU asset and the amounts recorded as interest. Leases with an initial term of 12 months or less are considered short term and are not recorded on the balance sheet. The Company recognizes a lease expense for short term leases on a straight-line basis over the lease term.

Certain of the Company's leases may also include rent 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 the Company will exercise that option. None of the Company’s current leases contain guarantees of residual value.

The Company determines whether an arrangement is a lease at the inception of the contract. Resulting operating lease right of use assets are recorded on the Consolidated Balance Sheets as a component of "Other assets" and resulting operating lease liabilities are recorded as a component of "Accrued expenses" and "Other long-term liabilities". Generally, the Company’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. 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, 2020, all of the Company’s finance leases pertain to certain equipment used in the business.

For the years ended December 31, 2020 and 2019, the Company’s effective tax rate was (9.4)% and 42.5%, respectively. In 2020, the Company had a significant decrease in its rate due to the carryback of U.S net operating losses as allowed by the CARES Act. In 2019, the Company had a higher effective rate due to the mix of earnings across jurisdictions and valuation allowance recorded on certain losses.

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.

The United States fully utilized its federal net operation losses due to the passage of the CARES Act. In addition to net operating loss attributes, the Company has recorded a foreign tax credit carryforward of $4.6 million, which will begin to expire in 2025. The Company maintains a full valuation against the foreign tax credits.

At December 31, 2020 and 2019, the Company’s valuation allowance was $11.9 million and $12.4 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 allowance against the Company's deferred tax assets consisted of the following at December 31 (in thousands):

On January 1, 2007, the Company adopted FIN 48, which was codified into Topic 740, which 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. As of December 31, 2020, 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, 2020, 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, 2020 and 2019 (in thousands):

The Company recognizes interest and/or penalties related to uncertain tax positions in current income tax expense. For each of the years ended December 31, 2020 and 2019, the Company had accrued interest and penalties of $0.1 million in the consolidated balance sheet, of which $11 thousand and $13 thousand were expensed in the consolidated statement of operations, for December 31, 2020 and 2019, respectively. 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, 2020, the tax years that remained subject to examination by a major tax jurisdiction for the Company’s most significant subsidiaries were as follows:

EMPLOYEE BENEFIT PLANS

Employee Retirement Plan

Effective May 9, 1997, the Company adopted a Defined Contribution 401(k) and Profit Sharing Plan (the “401(k) Plan”) for its United States and Canada employees. The 401(k) Plan covers all regular full-time and part-time employees who have completed three months of service and attained the age of twenty-one. United States employees can contribute up to 100 percent of their annual compensation but are limited to the maximum annual dollar amount allowable under the Internal Revenue Code. The 401(k) plan permits matching and discretionary employer contributions. The Company’s matching contributions for its United States and Canada employees vest ratably over a five-year period. During each of the years ended December 31, 2020 and 2019, the Company contributed approximately $0.2 million and $0.3 million to the 401(k) Plan for matching contributions, respectively.

The Company also sponsors a non-U.S. defined benefit plan covering its employees in its Japan subsidiary (the “Benefit Plan”). Benefits under the Benefit Plan are based on a point system for position grade and years of service. The Company utilizes actuarial methods. Inherent in the application of these actuarial methods are key assumptions, including, but not limited to, discount rates and expected long-term rates of return on plan assets. Changes in the related Benefit Plan costs may occur in the future due to changes in the underlying assumptions, changes in the number and composition of plan participants, and changes in the level of benefits provided. The Company uses a measurement date of December 31 to evaluate and record any post-retirement benefits related to the Benefit Plan.

The Company currently has one active stock-based compensation plan, the 2017 Plan, which was adopted by the Company’s Board of Directors on April 17, 2017 and was approved by its shareholders on June 8, 2017, and subsequently amended by the Board in February 2019, which was approved by the Company's shareholders on June 11, 2019. 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, 2020, the Company had a total of 165,393 shares available for grant under the 2017 Plan, which expires on April 16, 2027.

A summary of changes in stock options outstanding during the year ended December 31, 2020, is as follows:


	2020
	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	381	$	16.24

During 2020, the Company issued 28,157 new shares upon the exercise of options and granted 5,000 new options to management and members of the Board. Options exercised during the year ending December 31, 2020 and December 31, 2019 had a total intrinsic value, calculated as the difference between the exercise date stock price and the exercise price of $0.1 million and less than $0.1 million, respectively. Non-vested shares at December 31, 2020 and 2019 were approximately 8,336 and 55,335, 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:


	2020		2019
Dividend yield:	3.0	%	7.5	%
Risk-free interest rate:	.3	%	1.9	%
Expected market price volatility:	52.5	%	47.6	%
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 volatility 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, 2020 and 2019 was $4.00 and $3.72 per share, respectively. The total fair value of awards vested during the years ended December 31, 2020 and 2019 was $0.3 million and $0.4 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, 2020 and 2019 (in thousands):


	2020		2019
Selling, general and administrative expenses and income from operations before income taxes	$	124	$	456
Benefit for income taxes	(9)		(23)
Effect on net income	$	115	$	433

As of December 31, 2020, the Company had less than $0.1 million of total unrecognized compensation expense related to stock options 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

LITIGATION [Abstract]
LITIGATION	LITIGATION Administrative Proceedings Mannatech Korea, Ltd. v. Busan Custom Office, Busan District Court, Korea On or before April 12, 2015, Mannatech Korea Co., Ltd. (“Mannatech Korea”) filed a suit against the Busan Custom Office (“BCO”) to challenge BCO’s method of calculation regarding its assessment notice issued on July 11, 2013. The assessment notice included an audit of Mannatech Korea’s imported goods covering fiscal years 2008 through 2012 and required Mannatech Korea to pay $1.0 million for this assessment, all of which was paid in January 2014. Both parties submitted a response to the Court’s inquiry on January 15, 2016. The final hearing for the case was held on May 26, 2016 where each party presented their respective arguments. The Court set the decision hearing on October 27, 2016, and the Court decided the case in Mannatech Korea’s favor. However, on November 18, 2016, BCO filed an appeal to the Busan High Court. The first hearing occurred on March 31, 2017, and the second hearing occurred on April 21, 2017. The final hearing was held on June 2, 2017. The Court issued its decision on June 30, 2017 in favor of the BCO. Mannatech Korea appealed this decision on August 24, 2017. On December 24, 2020 Mannatech Korea received notice that the Court issued its decision and ruled to reject its appeal, which means the customs imposition is now final and conclusive. Mannatech Korea and the Company consider this matter closed. Litigation - Product Liability Meeja Kim, et al., v. Mannatech Korea and Eunbee Cho, Seoul Southern District Court 2020-Gadan-216374 On March 4, 2020, a complaint was filed against Mannatech Korea. Mannatech Korea was served on March 10, 2020. The plaintiffs are the surviving spouse and three children (the “Plaintiffs”) of Kong Seokhwan, a cancer patient who died in October 2017. The Plaintiffs allege that co-defendant and former independent associate, Eunbee Cho, instructed the deceased to take the Company’s products as treatment for cancer. Eunbee Cho was found guilty of fraud and began serving a sentence of one year and six months in November 2019. The Plaintiffs are seeking damages in the amount of 110 million KRW (USD $90,000.00) plus interest of 12% per year. Mannatech Korea has engaged local counsel to defend this matter. An evidentiary hearing was held on October 21, 2020. Due to restrictions in place relating to COVID-19, hearings scheduled during the fourth quarter of 2020 for this matter were postponed; an evidentiary hearing was held on March 10, 2021 where another hearing was scheduled for April 28, 2021. It is not possible at this time to predict whether Mannatech Korea will incur any liability, or to estimate the ranges of damages, if any, which may be incurred in connection with this matter. However, Mannatech Korea believes it has a valid defense and will vigorously defend this claim. This matter remains open. Ruiguo Ma v. MTEX Hong Kong Limited and Beili Guan, Case No. 2019-Jin-0116-Civil-2339, Binhai New District Court, Tianjin, China On or before September 2, 2019, MTEX Hong Kong Limited (“MTEX Hong Kong”) received service of process of the above-captioned matter. Ruiguo Ma (the "Plaintiff") is alleging that his child suffered tooth decay after consuming the Company's MannaBears product and underwent several surgeries. The Plaintiff is seeking damages of approximately $50,000 USD. MTEX Hong Kong has engaged local counsel to defend this case. The Company has provided notice to its insurance carrier. At this time the potential damages do not meet the deductible; therefore, the case has not been tendered to the carrier. The first hearing occurred on September 11, 2019, and the second hearing occurred on October 30, 2019, where each party presented their respective arguments. On August 25, 2020, the court denied all of the Plaintiff's motions and granted judgment in favor of MTEX Hong Kong. The Plaintiff appealed the decision on September 21, 2020. On January 27, 2021, the appellate court issued a judgment upholding the lower court’s decision. MTEX Hong Kong and the Company consider this matter closed. Hong Wang v. Beili Guan, MTEX Hong Kong Limited, and Mannatech, Incorporated, Case No. 2020-Jin-0116- Civil-7655, Binhai New District Court, Tianjin, China On November 16, 2020, MTEX Hong Kong received service of process of the above-captioned matter. Hong Wang (the “Plaintiff”) is alleging that various Mannatech’s products that she purchased violate the China Food Safety Law. In addition, Plaintiff alleges that her son suffered from tooth decay after consuming the MannaBears product and that the product violates the China Consumer Protection Law. The Plaintiff is seeking damages of approximately USD $286,600. On November 22, 2020, MTEX Hong Kong filed a motion challenging the court’s jurisdiction. It is not possible at this time to predict whether MTEX Hong Kong will incur any liability, or to estimate the ranges of damages, if any, which may be incurred in connection with this matter. However, MTEX Hong Kong 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. No legal reserve was deemed necessary at December 31, 2020.

Equity [Abstract]

SHAREHOLDERS' EQUITY

SHAREHOLDERS’ EQUITY

Preferred Stock

On May 19, 1998, the Company amended its Amended and Restated Articles of Incorporation to reduce the number of authorized shares of common stock from 100.0 million to 99.0 million and the Company authorized 1.0 million shares of preferred stock with a par value of $0.01 per share. No shares of preferred stock have ever been issued or outstanding.

Treasury Stock

On June 30, 2004, the Company’s Board of Directors authorized the Company to repurchase, in the open market, the lesser of (i) 131,756 shares of its common stock and (ii) $1.3 million of its shares, (the “June 2004 Plan”). On August 28, 2006, a second program permitting the Company to purchase, in the open market, up to $20 million of its outstanding shares was approved by our Board of Directors (the “August 2006 Plan”). On July 14, 2011, the Company’s Board of Directors authorized the Company to reactivate the June 2004 Plan. On August 31, 2016, the Company's Board of Directors reactivated the August 2006 Plan. In August of 2016, and December of 2017, the Company's Board of Directors authorized the Company to repurchase up to $0.5 million, respectively, of the Company's outstanding common shares in open market transactions. In August of 2018 and November of 2018, the Company's Board of Directors reactivated an additional $0.5 million (of the original $20.0 million authorization), respectively, in shares of the Company's common stock to be repurchased in the open market. In December of 2019, the Company’s Board of Directors approved a share repurchase program to acquire up to $1.0 million (of the original $20.0 million authorization) of the Company’s common stock through March 1, 2020. In August 2020, the Company’s Board of Directors approved a share repurchase program to acquire up to $1.0 million (of the original $20.0 million authorization) of the Company’s common stock through August 16, 2021. As of August 8, 2017, the maximum number of shares available for repurchase under the June 2004 Plan was 19,084, and the total number of shares purchased in the open market under the June 2004 Plan was 112,672. As of December 31, 2020, there was $12.6 million remaining for repurchase under the August 2006 Plan, and the total value of shares repurchased in the open market under the August 2006 Plan was $1.5 million. The Company does not have any stock repurchase plans or programs other than the June 2004 Plan and the August 2006 Plan.

On May 29, 2020, the Company commenced a modified Dutch auction cash tender offer to purchase up to $5.0 million of its outstanding common stock, par value $0.0001 per share, at a per share price not greater than $17.00 nor less than $15.00, to each seller in cash, less any applicable withholding taxes and without interest (the "tender offer"). The tender offer expired on June 25, 2020. As a result of the tender offer, the Company accepted for purchase a total of 294,117 shares of its common stock, which were properly tendered and not properly withdrawn at the price of $17.00 per share, for an aggregate purchase price of $5.0 million, which was funded from cash on hand. Due to the tender offer being oversubscribed, the Company purchased only a prorated portion of those shares properly tendered by each tendering shareholder (other than "odd lot" holders whose shares were purchased on a priority basis) at or below the final per share purchase price. The final proration factor for the tender offer was approximately 86%. The common shares represented approximately 12.31% of the Company's total outstanding shares as of April 30, 2020.

During the year ended December 31, 2020, the Company repurchased 351,581 shares of its common stock, which includes the 294,117 shares repurchased pursuant to the tender offer, at an average price of $17.79. During the year ended December 31, 2019, the Company repurchased 18,753 shares at an average price of $16.25.

EARNINGS PER SHARE	12 Months Ended
EARNINGS PER SHARE	Dec. 31, 2020
Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE The Company calculates basic Earnings per Share ("EPS") by dividing net income 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 2020, the Company used the average common stock close price of $15.34 per share. For the year ended December 31, 2020, there were 2.24 million weighted-average common shares outstanding used for the basic EPS calculation. For the year ended December 31, 2020, approximately 0.03 million shares subject to options were included in the calculation resulting in 2.26 million dilutive shares used to calculate diluted EPS. For the year ended December 31, 2020, approximately 0.9 million of the Company's common stock subject to options were excluded from the diluted EPS calculation as the effect would have been antidilutive. 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. For the year ended December 31, 2019, 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 common stock subject to options were excluded from the diluted EPS calculation as the effect would have been antidilutive.

Segment Reporting [Abstract]

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-four countries. Each of the business units receives associate fees or sells similar packs (in the case of Mexico and South Korea, where packs have not 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 pack sales and associate fees 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 eleven countries and sells product in twenty-five 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 and China. Each facility services different geographic areas. We currently sell our products in three regions: (i) the Americas (the United States, Canada 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).

Unrecognized tax benefits

Topic 740, which 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. As of December 31, 2020, 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, 2020, the Company had unrecognized tax benefits of $0.2 million that, if recognized, would impact the effective tax rate.
