Significant Accounting Policies [Text Block] | 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated on consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Significant accounting estimates reflected in the Company’s consolidated financial statements include valuation allowance for deferred income tax assets, allowance for doubtful accounts, impairment of long-term investments, inventory valuation, useful lives for property and equipment, impairment of long-lived assets, pension and uncertain tax liabilities, and contingencies. The COVID- 19 not December 31, 2021 2020. not Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents, restricted cash, short-term investments and accounts receivable. Cash is deposited with high credit quality financial institutions. For cash equivalents, restricted cash and short-term investments, the Company invests primarily in time deposits at the banks with good credit rating. For accounts receivable, the Company performs ongoing credit evaluations of its customers’ financial condition and the Company maintains an allowance for doubtful accounts based upon a review of the expected collectability of individual accounts. For the year ended December 31, 2021, one December 31, 2021. December 31, 2020, two two December 31, 2020. Additionally, for the year ended December 31, 2021, five five December 31, 2021. December 31, 2020, four four December 31, 2020. Fair Value of Financial Instruments The Company’s financial instruments include cash and cash equivalents, restricted cash, short-term investments, long-term investments, accounts receivable and accounts payable. The carrying amounts approximate the fair value due to the short-term maturity of those instruments. Long-term investments in public company equity securities are measured using the quoted market prices. Long-term investments in private company equity securities are measured at cost with adjustments for observable changes in price or impairments. Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of not three three Restricted Cash The Company classifies deposits made for customs and cash pledged to a bank for the issuance of letters of credit as restricted cash.

Major additions and betterments are capitalized, while maintenance and repairs are expensed as incurred. Depreciation is computed on a straight-line basis over estimated service lives that range as follows: buildings - 35 to 50 years, equipment - 3 to 7 years, furniture and fixtures - 3 to 7 years, leasehold improvements - the shorter of the estimated useful life or the lease term, which is 2 to 5 years, and transportation equipment - 5 years.

A lease exists when a contract conveys to the customer the right to control the use of an identified asset for a period of time in exchange for consideration. The definition of a lease embodies two 1 2 not not Payments for leases of low-value assets under the Company’s capitalization policy and short-term leases with a lease term less than 12 For lease arrangements where the Company is the lessor, the Company recognizes lease income from operating leases on a straight-line basis over the lease term.

The Company determines revenue recognition through the following steps: ( 1 2 3 4 5 Product Sales The Company generates revenue primarily from product sales, either directly to a customer or through a distributor. Revenue from product sales is recognized upon transfer of control of promised products to direct end customers or distributor in an amount that reflects the consideration the Company expects to receive in exchange for those products. In determining whether a contract exists, the Company evaluates the terms of the arrangement including rights, obligations and payment term, the relationship with the customer or distributor and their ability to pay. At contract inception, the Company assesses the goods and shipping services promised in its contracts with customers and identifies a single performance obligation that the Company satisfies at a point in time. Payment for sales to customers is generally due on standard commercial terms. The revenue recognized is adjusted based on an analysis of historical data and contractual terms. These adjustments, which are not Licensing revenue The Company recognizes licensing revenues when the Company satisfies a performance obligation by transferring a promised service (that is, an asset) to a customer. An asset is transferred when the customer obtains control of that asset. Freight Costs Costs of shipping and handling for delivery of the Company’s products that are reimbursed by customers are included as revenue in the consolidated statements of operations and comprehensive income. Shipping and handling costs are charged to cost of revenues as incurred. Research and Development Research and development costs consist of expenditures incurred during the course of planned research and investigation aimed at the discovery of new knowledge and intellectual property that will be useful in developing new products or processes, or at significantly enhancing existing products or production processes as well as expenditures incurred for the design and testing of product alternatives or construction of prototypes.

December 2020, Income Tax The provision for income tax represents income tax paid and payable for the current year plus the changes in the deferred income tax assets and liabilities during the relevant years. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. The Company believes that uncertainty exists regarding the realizability of certain deferred income tax assets and, accordingly, has established a valuation allowance for those deferred income tax assets to the extent the realizability is not not. The Company utilizes a two first not second 50% Stock-based Compensation The Company grants stock options to its employees and certain non-employees and estimates the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service periods. The Company has elected to use the Black-Scholes option pricing model to determine the fair value of stock options on the date of grant. The Company also grants RSUs to its employees and the RSUs are measured based on the fair market value of the underlying stock on the date of grant. Foreign Currency Transactions The functional currency is the local currency of the respective entities. Foreign currency transactions are recorded at the rate of exchange in effect when the transaction occurs. Gains or losses, resulting from the application of different foreign exchange rates when cash in foreign currency is converted into the entities’ functional currency, or when foreign currency receivable and payable are settled, are credited or charged to income in the period of conversion or settlement. At year-end, the balances of foreign currency monetary assets and liabilities are recorded based on prevailing exchange rates and any resulting gains or losses are credited or charged to non-operating income or loss. Translation of Foreign Currency Financial Statements The reporting currency of the Company is the US dollar. Accordingly, the financial statements of the foreign subsidiaries are translated into US dollars at the following exchange rates: assets and liabilities - current rate on balance sheet date; shareholders’ equity - historical rate; income and expenses - weighted average rate during the year. The resulting translation adjustment is recorded as a separate component of shareholders’ equity. Comprehensive Income (Loss) Comprehensive income (loss) represents net income (loss) plus the results of certain changes in shareholders’ equity during a period from non-owner sources .

A reconciliation of the numerator and denominator of basic and diluted earnings (loss) per share calculations was as follows: Years Ended December 31 2021 2020 2019 Net income (loss) (in thousands) $ 12,113 $ 6,127 $ (5,039 ) Weighted average shares outstanding (in thousands) – basic 1,418,541 1,348,899 1,316,032 Effect of dilutive securities: Options and RSUs (in thousands) 137,489 87,309 - Weighted average shares outstanding (in thousands) – diluted 1,556,030 1,436,208 1,316,032 Earnings (loss) per share Basic $ 0.01 $ - $ - Diluted $ 0.01 $ - $ - Earnings (loss) per ADS Basic $ 0.43 $ 0.23 $ (0.19 ) Diluted $ 0.39 $ 0.21 $ (0.19 ) Certain outstanding options and RSUs were excluded from the computation of diluted EPS since their effect would have been anti-dilutive. The anti-dilutive stock options excluded and their associated exercise prices per share were 45,556,000 shares at $0.1270 to $0.1790 as of December 31, 2021, December 31, 2020, December 31, 2019.

In determining whether a contract exists, the Company evaluates the terms of the arrangement including rights, obligations and payment term, the relationship with the customer or distributor and their ability to pay. At contract inception, the Company assesses the goods and shipping services promised in its contracts with customers and identifies a single performance obligation that the Company satisfies at a point in time. Payment for sales to customers is generally due on standard commercial terms. The revenue recognized is adjusted based on an analysis of historical data and contractual terms.
