Summary of significant accounting policies | Note 2 – Summary of significant accounting policies Principal of Consolidation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The consolidated financial statements include the financial statements of Tantech BVI and its subsidiaries, and entities controlled through a series of agreements known as variable interest agreements (“VIE”) (collectively, the “Company”). All significant inter-company balances and transactions are eliminated upon consolidation. Non-controlling interest Non-controlling interest represents 30% of the equity interest in Shangchi Automobile and its subsidiary Shenzhen Yimao owned by Zhangjiagang Jinke Chuangtou Co., Ltd., which is not under the Company’s control. Business Combinations Business combinations are accounted for under the purchase method of accounting. Under the purchase method, assets and liabilities of the business acquired are recorded at their estimated fair values as of the date of acquisition with any excess of the cost of the acquisition over the fair value of the net tangible and intangible assets acquired recorded as goodwill. Results of operations of the acquired business are included in the statement of comprehensive income from the date of acquisition. Reclassification Certain prior year amounts have been reclassified to conform to the current year presentation, such as reclassification of customer advance to due to related parties, presentation of discontinued operations due to disposition of Tantech Energy in fiscal 2019. These reclassifications had no effect on the reported revenues, net income (loss) and cash flows. Discontinued operation In accordance with ASU No. 2014‑08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, a disposal of a component of an entity or a group of components of an entity is required to be reported as discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the components of an entity meets the criteria in paragraph 205‑20‑45‑1E to be classified as held for sale. When all of the criteria to be classified as held for sale are met, including management, having the authority to approve the action, commits to a plan to sell the entity, the major current assets, other assets, current liabilities, and noncurrent liabilities shall be reported as components of total assets and liabilities separate from those balances of the continuing operations. At the same time, the results of all discontinued operations (which we presented as operations to be disposed and operations disposed), less applicable income taxes (benefit), shall be reported as components of net income (loss) separate from the net income (loss) of continuing operations in accordance with ASC 205‑20‑45. Use of Estimates In preparing the consolidated financial statements in conformity with US GAAP, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the dates of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting year. Significant items subject to such estimates and assumptions include the fair value estimates used in the purchase price allocation, the useful lives of property and equipment and intangible assets, allowances pertaining to the allowance for doubtful accounts and advance to suppliers, the valuation of inventories, the impairment of long-lived assets, and the realizability of deferred tax assets. Fair Value of Financial Instruments The Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurements”, defines fair value, establishes a three-level valuation hierarchy for fair value measurements and enhances disclosure requirements. The three levels are defined as follows: Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted market prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data. Level 3 - inputs to the valuation methodology are unobservable. Unless otherwise disclosed, the fair value of the Company’s financial instruments including cash, restricted cash, accounts receivable, advances to suppliers, other receivables, accounts payable, customer deposits, accrued expenses, short term bank loans and bank acceptance notes payable approximates their recorded values due to their short-term maturities. Cash and cash equivalents For purposes of the statements of cash flows, the Company considers all highly liquid instruments purchased with an original maturity of three months or less and money market accounts to be cash equivalents. All cash balances are in bank accounts in PRC and are not insured by the Federal Deposit Insurance Corporation or other programs. Restricted Cash Restricted cash represents required cash deposits as a part of collateral for bank acceptance notes payable and letters of credit. The Company is required to maintain 0% to 100% of the balance of the bank acceptance notes payable in restricted cash to ensure future credit availability. The Company earns interest at a variable rate per month on this restricted cash. Concentrations of credit risk Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash, trade accounts receivable and advances to suppliers. All of the Company’s cash is maintained with banks within the People’s Republic of China of which no deposits are covered by insurance. The Company has not experienced any losses in such accounts. A significant portion of the Company’s sales are credit sales which are primarily to customers whose ability to pay is dependent upon the industry economics prevailing in these areas. The Company also makes cash advances to certain suppliers to ensure the stable supply of key raw materials. The Company performs ongoing credit evaluations of its customers and key suppliers to help further reduce credit risk. Accounts receivable Accounts receivable are presented at invoiced amount net of an allowance for doubtful accounts. The Company maintains an allowance for doubtful accounts for estimated losses. The Company reviews its accounts receivable on a periodic basis and makes general and specific allowances when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balances, the Company considers many factors, including the age of the balance, customer’s payment history, its current credit-worthiness and current economic trends. Accounts are written off after efforts at collection prove unsuccessful. Inventory The Company values its inventories at the lower of cost, determined on a weighted average basis, or net realizable value. The Company reviews its inventories periodically to determine if any reserves are necessary for potential obsolescence or if a write-down is necessary if the carrying value exceeds net realizable value. Advances to suppliers In order to ensure a steady supply of raw materials, the Company is required from time to time to make cash advances when placing its purchase orders. The Company reviews its advances to suppliers on a periodic basis and makes general and specific allowances when there is doubt as to the ability of a supplier to refund an advance or provide supplies to the Company. Property and Equipment and Construction in Progress Property and equipment are stated at cost less accumulated depreciation. The cost of an asset comprises its purchase price and any directly attributable costs of bringing the asset to its present working condition and location for its intended use. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets. The estimated useful lives for significant property and equipment are as follows: Buildings 20 years Machinery and equipment 5 - 10 years Transportation equipment 4 - 5 years Office equipment 4 - 5 years Electronic equipment 3 - 5 years Repairs and maintenance costs are normally charged to earnings in the year in which they are incurred. In situations where it can be clearly demonstrated that the expenditure has resulted in an increase in the future economic benefits expected to be obtained from the use of the asset, the expenditure is capitalized as an additional cost of the asset. Construction in progress includes direct costs of construction or acquisition of equipment, interest expense associated with the loans used for the construction and design fees incurred. Capitalization of these costs ceases and the construction in progress is transferred to plant and equipment when substantially all the activities necessary to prepare the assets for their intended use are completed. No depreciation is provided until it is completed and ready for its intended use. Intangible assets Intangible assets are acquired individually or as part of a group of assets, and are initially recorded at cost. The cost of a group of assets acquired in a transaction is allocated to the individual assets based on their relative fair values. Intangible assets are carried at cost less accumulated amortization and any recorded impairment. Intangible assets with finite useful lives are amortized using a straight-line method over the period of estimated useful life. The estimated useful lives of the Company’s intangible assets are as follows: Estimated Useful Life Licenses and permits Indefinite Software 5 - 10 years Land use right 50 years Patents 10 years The Company evaluates intangible assets for impairment whenever events or changes in circumstances indicate that the assets might be impaired. Goodwill Goodwill represents the excess of the consideration over the fair value of the net assets acquired at the date of acquisition. Goodwill is not amortized but rather tested for impairment at least annually at the reporting unit level by applying a fair-value based test in accordance with accounting and disclosure requirements for goodwill and other indefinite-lived intangible assets. This test is performed by management annually or more frequently if the Company believes impairment indicators are present. The Company has the option to assess qualitative factors first to determine whether it is necessary to perform the two-step test in accordance with ASC 350-20, Intangibles - Goodwill and Other. If the Company believes, as a result of the qualitative assessment, that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount, the two-step quantitative impairment test described above is required. Otherwise, no further testing is required. In the qualitative assessment, the Company considers primary factors such as industry and market considerations, overall financial performance of the reporting unit, and other specific information related to the operations. In performing the two-step quantitative impairment test, the first step compares the carrying amount of the reporting unit to the fair value of the reporting unit based on estimated fair value using the income approach. If the fair value of the reporting unit exceeds the carrying value of the reporting unit, goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the reporting unit exceeds the fair value of the reporting unit, then the Company must perform the second step of the impairment test in order to determine the implied fair value of the reporting unit's goodwill. The fair value of the reporting unit is allocated to its assets and liabilities in a manner similar to a purchase price allocation in order to determine the implied fair value of the reporting unit’s goodwill. If the carrying amount of the goodwill is greater than its implied fair value, the excess is recognized as an impairment loss in general and administrative expenses. As of December 31, 2019, the Company wrote off the goodwill acquired from the acquisition of Shangchi Automobile (formerly known as Suzhou E-Motors) in fiscal 2017 of $8,480,668. Long term investments The Company accounts for investment in equity investees over which it has significant influence but does not own a majority of the equity interest or lack of control using the equity method. For investment in equity investees over which the Company does not have significant influence or the underlying shares the Company invested in are not considered in-substance common stock and have no readily determinable fair value, the cost method accounting is applied. The Company records the equity method investments at historical cost and subsequently adjusts the carrying amount each period for share of the earnings or losses of the investee and other adjustments required by the equity method of accounting. Dividends received from the equity method investments are recorded as reductions in the cost of such investments. The Company records the cost method investments at historical cost and subsequently record any dividends received from the net accumulated earnings of the investee as income. Dividends received in excess of earnings are considered a return of investment and are recorded as reductions in the cost of the investments. Investment in equity investees are evaluated for impairment when facts or circumstances indicate that the fair value of the investment is less than its carrying value. An impairment is recognized when a decline in fair value is determined to be other-than-temporary. The Company reviews several factors to determine whether a loss is other-than-temporary. These factors include, but are not limited to, the: (i) nature of the investment; (ii) cause and duration of the impairment; (iii) extent to which fair value is less than cost; (iv) financial condition and near term prospects of the investments; and (v) ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. Impairment of Long-Lived Assets The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances, such as a significant adverse change to market conditions that will impact the future use of the assets, indicate that the carrying amount of an asset may not be fully recoverable. When these events occur, the Company evaluates the recoverability of long-lived assets by comparing the carrying amount of the assets to the future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Company recognizes an impairment loss based on the excess of the carrying amount of the assets over their fair value. Fair value is generally determined by discounting the cash flows expected to be generated by the assets, when the market prices are not readily available. Customer Deposits Customer deposits represent amounts received from customers in advance of shipments relating to the sales of the Company’s products. Due to Third Parties Due to third parties represent amounts the Company borrowed from third parties for working capital purpose. The due to third parties balance are unsecured, interest-free and due upon demand. As of December 31, 2020 and 2019, the due to third parties balance amounted to $306,600 and $287,200, respectively. Leases In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-02, Leases. The standard requires lessees to recognize lease assets and lease liabilities on the balance sheet and requires expanded disclosures about leasing arrangements. The new standard establishes a right-of-use model ("ROU") that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. The Company adopted this standard on January 1, 2019 on a modified retrospective basis and elected the practical expedients permitted under the transition guidance, which allows the Company to carryforward the historical lease classification, the assessment on whether a contract is or contains a lease, and the initial direct costs for any leases that exist prior to adoption of the new standard. Leases with an initial term of 12 months or less are not recognized on the balance sheet and the associated lease payments are included in the consolidated statements of comprehensive income (loss) on a straight-line basis over the lease term. The new standard has no material effect on the consolidated financial statements as the Company does not have a lease with a term longer than 12 months. Revenue Recognition The Company adopted ASC Topic 606 Revenue from Contracts with Customers (“ASC 606”) on January 1, 2018 using the modified retrospective approach. There is no adjustment to the opening balance of retained earnings at January 1, 2018 since there was no change to the timing and pattern of revenue recognition upon adoption of ASC 606. Under ASC 606, revenue is recognized when control of promised goods or services is transferred to the Company’s customers in an amount of consideration to which an entity expects to be entitled to in exchange for those goods or services. The Company’s revenues are primarily derived from the following sources: Sales of products: The Company recognizes sales revenue, net of sales taxes and estimated sales returns, at the time the product is delivered to the customer and control is transferred (point of sale). Commission income: The Company acts as an agent without assuming the risks and rewards of ownership of the goods and reports the revenue on a net basis. Revenue is recognized based on the completion of the contracted service. Government manufacturing rebate income: The Company sells electric vehicles in China and is eligible for a government manufacturing rebate on each qualifying electric vehicle sold. The government manufacturing rebates are recognized as part of revenue when sales are finalized, amount of rebates can be reasonably estimated and collection is assured. The collectability of rebates can be assured as long as the sales are deemed qualifying based on the criteria set by the government. Revenue is reported net of all value added taxes. The Company does not routinely permit customers to return products and historically, customer returns have been immaterial. Cost of Revenues Cost of revenues includes cost of raw materials purchased, inbound freight cost, cost of direct labor, depreciation expense and other overhead. Write-down of inventory for lower of cost or net realizable value adjustments is also recorded in cost of revenues. Shipping and Handling Shipping and handling costs are expensed as incurred and included in selling expenses. Subsidy Income The Company periodically receives various government grants such as “High Technology Projects Subsidy” and “Scientific Research Grant”. There is no guarantee the Company will continue to receive such grants in the future. Foreign Currency Translation The Company’s financial information is presented in U.S. dollars. The functional currency of the Company’s subsidiaries in the PRC is the RMB, the currency of the PRC. Any subsidiary transactions, which are denominated in currencies other than RMB, are translated into RMB at the exchange rate quoted by the People’s Bank of China prevailing at the dates of the transactions, and exchange gains and losses are included in the statements of comprehensive income (loss) as foreign currency transaction gain or loss. The consolidated financial statements of the Company have been translated into U.S. dollars in accordance with ASC 830, “Foreign Currency Matters”. The financial information is first prepared in RMB and then is translated into U.S. dollars at period-end exchange rates for assets and liabilities and average exchange rates for revenue and expenses. Capital accounts are translated at their historical exchange rates when the capital transactions occurred. The effects of foreign currency translation adjustments are included as a component of accumulated other comprehensive income in stockholders’ equity. Cash flows from the Company’s operations are calculated based upon the local currencies using the average translation rate. As a result, amounts related to assets and liabilities reported on the statements of cash flows will not necessarily agree with changes in the corresponding balances on the balance sheets. The following table outlines the currency exchange rates that were used in creating the consolidated financial statements in this report: December 31, 2020 December 31, 2019 December 31, 2018 US$:RMB exchange rate Period End $ 0.1533 Period End $ 0.1436 Period End $ 0.1513 Average $ 0.1448 Average $ 0.1448 Average $ 0.1454 Comprehensive Income (loss) Comprehensive income (loss) consists of two components, net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) refers to revenue, expenses, gains and losses that under GAAP are recorded as an element of stockholders’ equity but are excluded from net income (loss). Other comprehensive income (loss) consists of foreign currency translation adjustment from those subsidiaries not using the U.S. dollar as their functional currency. Income Taxes The Company’s subsidiaries in China are subject to the income tax laws of the PRC. No taxable income was generated outside the PRC for the years ended December 31, 2020, 2019 and 2018. The Company accounts for income taxes in accordance with ASC 740, “Income Taxes”. ASC 740 requires an asset and liability approach for financial accounting and reporting for income taxes and allows recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for 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. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or future deductibility is uncertain. ASC 740‑10‑25 prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken (or expected to be taken) in a tax return. It also provides guidance on the recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, years open for tax examination, accounting for income taxes in interim periods and income tax disclosures. There were no material uncertain tax positions as of December 31, 2020 and 2019. All tax returns since the Company’s inception are subject to examination by tax authorities. Value Added Tax (“VAT”) The Company is subject to VAT for selling merchandise. The applicable VAT rate is 11% or 13% or 17% (depending on the type of goods involved) for products sold in the PRC. The applicable VAT rate of 17% and 11% decreased to 16% and 10% starting from May 2018, and further decreased to 13% and 9% from April 1, 2019. The amount of VAT liability is determined by applying the applicable tax rate to the invoiced amount of goods sold (output VAT) less VAT paid on purchases made with the relevant supporting invoices (input VAT). Under the commercial practice of the PRC, the Company pays VAT based on tax invoices issued. The tax invoices may be issued subsequent to the date on which revenue is recognized, and there may be a considerable delay between the date on which the revenue is recognized and the date on which the tax invoice is issued. In the event the PRC tax authorities dispute the date on which revenue is recognized for tax purposes, the PRC tax office has the right to assess a penalty based on the amount of taxes which is determined to be late or deficient, with any penalty being expensed in the period when a determination is made by the tax authorities that a penalty is due. During the reporting periods, the Company had no dispute with PRC tax authorities and there was no tax penalty incurred. Earnings (loss) per Share (“EPS”) The Company computes earnings (loss) per share (“EPS”) in accordance with ASC 260, “Earnings per Share” (“ASC 260”), and SEC Staff Accounting Bulletin No. 98 (“SAB 98”). ASC 260 requires companies with complex capital structures to present basic and diluted EPS. Basic EPS is measured as net income divided by the weighted average common shares outstanding for the period. Diluted EPS is similar to basic EPS but presents the dilutive effect on a per share basis of potential common shares (e.g., convertible securities, options and warrants) as if they had been converted at the beginning of the periods presented, or issuance date, if later. Potential common shares that have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted EPS. As of December 31, 2020 and 2019, the total number of registered and unregistered warrants outstanding was 6,557,635 and 1,078,045, respectively. For the years ended December 31, 2020, 2019 and 2018, no warrants were included in the diluted income (loss) per share as they would be anti-dilutive. Statement of Cash Flows In accordance with ASC 230, “Statement of Cash Flows,” cash flows from the Company’s operations are calculated based upon the local currencies. As a result, amounts related to assets and liabilities reported on the statements of cash flows will not necessarily agree with changes in the corresponding balances on the balance sheets. Risks and Uncertainties The operations of the Company are located in the PRC. Accordingly, the Company’s business, financial condition, and results of operations may be influenced by the political, economic, and legal environments in the PRC, in addition to the general state of the PRC economy. The Company’s results may be adversely affected by changes in the political and social conditions in the PRC, and by changes in governmental policies with respect to laws and regulations, anti-inflationary measures, currency conversion and remittance abroad, and rates and methods of taxation, among other things. The Company’s sales, purchases and expense transactions are denominated in RMB, and all of the Company’s assets and liabilities are also denominated in RMB. The RMB is not freely convertible into foreign currencies under the current law. In China, foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the People’s Bank of China, the central bank of China. Remittances in currencies other than RMB may require certain supporting documentation in order to affect the remittance. The Company does not carry any business interruption insurance, products liability insurance or any other insurance policy except for a limited property insurance policy. As a result, the Company may incur uninsured losses, increasing the possibility that investors would lose their entire investment in the Company. COVID-19 The Company’s operations are affected by the recent and ongoing outbreak of the coronavirus disease 2019 (COVID-19) which in March 2020, was declared a pandemic by the World Health Organization. The COVID-19 outbreak is causing lockdowns, travel restrictions, and closures of businesses. The Company’s business has been negatively impacted by the COVID-19 coronavirus outbreak to certain extent. From late January 2020 to the middle of February 2020, the Company had to temporarily suspend our manufacturing activities due to government restrictions. During the temporary business closure period, our employees had very limited access to our manufacturing facilities and the shipping companies were not available and as a result, the Company experienced difficulty delivering our products to the customers on a timely basis. In addition, due to the COVID-19 outbreak, some of the customers or suppliers may experience financial distress, delay or default on their payments, reduce the scale of their business, or suffer disruptions in their business due to the outbreak. Any increased difficulty in collecting accounts receivable, delayed raw materials supply, bankruptcy of small and medium businesses, or early termination of agreements due to deterioration in economic conditions could negatively impact our results of operations. During the year ended December 31, 2020, the Company’s revenues for consumer product segment decreased approximately 36% as compared to the same period of last year, however, the sales for trading segment increased significantly for approximately 269% due to the significant increased demand for bamboo charcoal used for air purification and sanitation products. As of the date of this filing, the COVID-19 coronavirus outbreak in China appears to have slowed down and most provinces and cities have resumed business activities under the guidance and support of the government. However, there is still significant uncertainty regarding the possibility of a second wave of infections, and the breadth and duration of business disruptions related to COVID-19, which could continue to have material impact to the Company’s operations. Recent accounting pronouncements The Company considers the applicability and impact of all accounting standards updates (“ASUs”). Management periodically reviews new accounting standards that are issued. In August 2018, the FASB Accounting Standards Board issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”). ASU 2018-13 modifies the disclosure requirements on fair value measurements. ASU 2018-13 is effective for public entities for fiscal years beginning after December 15, 2019, with early adoption permitted for any removed or modified disclosures. The removed and modified disclosures will be adopted on a retrospective basis and the new disclosures will be adopted on a prospective basis. The Company adopted this guidance in fiscal 2020 and this guidance did not have a material impact on the consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes” (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 will simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company does not expect that the requirements of ASU 2019-12 will have a material impact on its consolidated financial statements. In January 2020, the FASB issued ASU 2020-01, Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) (“ASU 2020-01”), which is intended to clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. ASU 2020-01 is effective for the Company beginning January 1, 2021. The Company is currently evaluating the effect of adopting this ASU on the Company’s financial statements. Except for the above-mentioned pronouncements, there are no new recent issued accounting standards that will have material impact on the consolidated financial statements. |
