Basis of presentation and significant accounting policies	2. Basis of presentation and significant accounting policies (a) Basis of Presentation Basis of Presentation – The accompanying condensed unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. The details of subsidiaries are disclosed in Note 1. Significant inter-company balances and transactions have been eliminated upon consolidation. The condensed unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions in Regulation S-X. Accordingly they do not include all of the information and footnotes required by such accounting principles for complete financial statements. These financial statements should be read in conjunction with the consolidated financial statements and related footnotes included in the Company’s Annual Report on Form 10‑K for the year ended December 31, 2018. The accompanying interim condensed consolidated financial statements are unaudited, but in the opinion of the Company’s management, contain all necessary adjustments, which include normal recurring adjustments, for a fair statement of the results of operations, financial position and cash flows for the interim periods presented. The condensed consolidated balance sheet as of December 31, 2018 is derived from the Company’s audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The results of operations for the three months and six months ended June 30, 2019 are not necessarily indicative of the results of operations to be expected for the full fiscal year ending December 31, 2019. Estimation - The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Foreign Currencies - China Automotive, the parent company, and HLUSA maintain their books and records in United States Dollars, “USD,” their functional currency. The Company’s subsidiaries based in the PRC and Genesis maintain their books and records in Renminbi, “RMB,” their functional currency. The Company’s subsidiary based in Brazil maintains its books and records in Brazilian reais, “BRL,” its functional currency. In accordance with ASC Topic 830, “FASB Accounting Standards Codification”, foreign currency transactions denominated in currencies other than the functional currency are remeasured into the functional currency at the rate of exchange prevailing at the balance sheet date for monetary items. Nonmonetary items are remeasured at historical rates. Income and expenses are remeasured at the rate in effect on the transaction dates. Transaction gains and losses, if any, are included in the determination of net income for the period. (b) Recent Accounting Pronouncements On January 1, 2019, the Company adopted ASU 2016‑02, Leases (as amended by ASU Nos. 2018‑10, 2018‑11, 2018‑20, and 2019‑01), using the modified retrospective method. The impact of the adoption of the new standard on the consolidated financial statements is discussed in “Significant Accounting Policies” below. (c) Significant Accounting Policies The following significant accounting policies have been added or changed since the date of the Company’s 2018 Annual Report on Form 10‑K. Leases - As described in the “Recent Accounting Pronouncements” section, the Company adopted ASU 2016‑02, Leases, and other related ASUs (collectively, “ASC 842”) on January 1, 2019, using the modified retrospective method of adoption. The Company elected the transition method, which allows entities to initially apply the requirements of ASC 842 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As a result of electing this transition method, prior periods have not been restated. There is no material impact on the balance of retained earnings, right of use assets or associated lease liabilities as of January 1, 2019 due to the adoption of ASC 842. The Company elected the package of practical expedients permitted under the transition guidance within ASC 842, which includes not reassessing lease classification of existing leases. The Company did not elect the hindsight practical expedient. The Company determines if an arrangement is a lease upon inception. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The right to control the use of an asset includes the right to obtain substantially all of the economic benefits of the underlying asset and the right to direct how and for what purpose the asset is used. The Company’s major plants and buildings are self-owned and limited temporary small offices were rented. For leases with a term of 12 months or less, the Company makes an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. The Company recognizes lease expenses for such leases on a straight-line basis over the lease term. Operating lease assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The discount rate used to calculate present value is the Company’s incremental borrowing rate or, if available, the rate implicit in the lease. The Company determines the incremental borrowing rate for each lease based primarily on the lease term and the economic environment of the applicable country or region. The discount rate used by the Company for its operating lease was 4.49%. The operating lease right of use assets of $0.4 million as of June 30, 2019 are included in other current assets. The current portion of operating lease liabilities of $0.1 million as of June 30, 2019 is included in other current liabilities and the non-current portion of $0.3 million as of June 30, 2019 is included in other non-current liabilities. The lease expenses recognized for the three months ended June 30, 2019 and 2018 were $4,000 and $4,000, respectively. The lease expenses recognized for the six months ended June 30, 2019 and 2018 were $7,000 and $7,000, respectively. The weighted average remaining lease term was 4 years. The Company does not have finance lease arrangements as of June 30, 2019.

Please refer to Note 24. Contract Assets and Liabilities Contract assets, such as costs to obtain or fulfill contracts, are an insignificant component of the Company’s revenue recognition process. The majority of the Company’s cost of fulfillment as a manufacturer of products is classified as inventory, fixed assets and intangible assets, which are accounted for under the respective guidance for those asset types. Other costs of contract fulfillment are immaterial due to the nature of the Company’s products and their respective manufacturing processes. Contract liabilities are mainly customer deposits. Customer Deposits As of June 30, 2019 and December 31, 2018, the Company has customer deposits of $1.3 million and $0.8 million, respectively. During the six months ended June 30, 2019, $6.3 million was received and $5.7 million (including $0.8 million from the beginning balance of customer deposits) was recognized as net product sales revenue. Customer deposits represent non-refundable cash deposits for customers to secure rights to an amount of products produced by the Company under supply agreements. When the products are shipped to customers, the Company will recognize revenue and bill the customers to reduce the amount of the customer deposit liability.

Significant concentrations

Significant concentrations	20. Significant concentrations A significant portion of the Company’s business is conducted in China where the currency is the RMB. Regulations in China permit foreign owned entities to freely convert the RMB into foreign currency for transactions that fall under the "current account", which includes trade related receipts and payments, interest and dividends. Accordingly, the Company’s Chinese subsidiaries may use RMB to purchase foreign exchange for settlement of such "current account" transactions without pre-approval. Regulations in the PRC currently permit payment of dividends of a PRC company only out of accumulated profits as determined in accordance with accounting standards and regulations in China. Under PRC law, China-based subsidiaries are required to set aside at least 10% of their after-tax profit based on PRC accounting standards each year to their general reserves until the cumulative amount reaches 50% of their paid-in capital. These reserves are not distributable as cash dividends or as loans or advances. These foreign-invested enterprises may also allocate a portion of their after-tax profits, at the discretion of their boards of directors, to their staff welfare and bonus funds. Any amounts so allocated may not be distributed and, accordingly, would not be available for distribution to Genesis and HLUSA. Transactions other than those that fall under the "current account" and that involve conversion of RMB into foreign currency are classified as "capital account" transactions; examples of "capital account" transactions include repatriations of investment by or loans to foreign owners, or direct equity investments in a foreign entity by a China domiciled entity. "Capital account" transactions require prior approval from China’s State Administration of Foreign Exchange, or SAFE, or its provincial branch to convert a remittance into a foreign currency, such as USD, and transmit the foreign currency outside of China. This system could be changed at any time and any such change may affect the ability of the Company or its subsidiaries in China to repatriate capital or profits, if any, outside China. Furthermore, SAFE has a significant degree of administrative discretion in implementing the laws and has used this discretion to limit convertibility of current account payments out of China. Whether as a result of a deterioration in the Chinese balance of payments, a shift in the Chinese macroeconomic prospects or any number of other reasons, China could impose additional restrictions on capital remittances abroad. As a result of these and other restrictions under the laws and regulations of the PRC, the Company’s PRC subsidiaries are restricted in their ability to transfer a portion of their net assets to the parent. The Company has no assurance that the relevant Chinese governmental authorities in the future will not limit further or eliminate the ability of the Company’s PRC subsidiaries to purchase foreign currencies and transfer such funds to the Company to meet its liquidity or other business needs. Any inability to access funds in China, if and when needed for use by the Company outside of China, could have a material and adverse effect on the Company’s liquidity and its business.

Basis of presentation and significant accounting policies
Basis of Presentation	(a) Basis of Presentation Basis of Presentation – The accompanying condensed unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. The details of subsidiaries are disclosed in Note 1. Significant inter-company balances and transactions have been eliminated upon consolidation. The condensed unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions in Regulation S-X. Accordingly they do not include all of the information and footnotes required by such accounting principles for complete financial statements. These financial statements should be read in conjunction with the consolidated financial statements and related footnotes included in the Company’s Annual Report on Form 10‑K for the year ended December 31, 2018. The accompanying interim condensed consolidated financial statements are unaudited, but in the opinion of the Company’s management, contain all necessary adjustments, which include normal recurring adjustments, for a fair statement of the results of operations, financial position and cash flows for the interim periods presented. The condensed consolidated balance sheet as of December 31, 2018 is derived from the Company’s audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The results of operations for the three months and six months ended June 30, 2019 are not necessarily indicative of the results of operations to be expected for the full fiscal year ending December 31, 2019. Estimation - The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Foreign Currencies - China Automotive, the parent company, and HLUSA maintain their books and records in United States Dollars, “USD,” their functional currency. The Company’s subsidiaries based in the PRC and Genesis maintain their books and records in Renminbi, “RMB,” their functional currency. The Company’s subsidiary based in Brazil maintains its books and records in Brazilian reais, “BRL,” its functional currency. In accordance with ASC Topic 830, “FASB Accounting Standards Codification”, foreign currency transactions denominated in currencies other than the functional currency are remeasured into the functional currency at the rate of exchange prevailing at the balance sheet date for monetary items. Nonmonetary items are remeasured at historical rates. Income and expenses are remeasured at the rate in effect on the transaction dates. Transaction gains and losses, if any, are included in the determination of net income for the period.
Recent Accounting Pronouncements	(a) Recent Accounting Pronouncements On January 1, 2019, the Company adopted ASU 2016‑02, Leases (as amended by ASU Nos. 2018‑10, 2018‑11, 2018‑20, and 2019‑01), using the modified retrospective method. The impact of the adoption of the new standard on the consolidated financial statements is discussed in “Significant Accounting Policies” below.
Significant Accounting Policies	(a) Significant Accounting Policies The following significant accounting policies have been added or changed since the date of the Company’s 2018 Annual Report on Form 10‑K. Leases - As described in the “Recent Accounting Pronouncements” section, the Company adopted ASU 2016‑02, Leases, and other related ASUs (collectively, “ASC 842”) on January 1, 2019, using the modified retrospective method of adoption. The Company elected the transition method, which allows entities to initially apply the requirements of ASC 842 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As a result of electing this transition method, prior periods have not been restated. There is no material impact on the balance of retained earnings, right of use assets or associated lease liabilities as of January 1, 2019 due to the adoption of ASC 842. The Company elected the package of practical expedients permitted under the transition guidance within ASC 842, which includes not reassessing lease classification of existing leases. The Company did not elect the hindsight practical expedient. The Company determines if an arrangement is a lease upon inception. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The right to control the use of an asset includes the right to obtain substantially all of the economic benefits of the underlying asset and the right to direct how and for what purpose the asset is used. The Company’s major plants and buildings are self-owned and limited temporary small offices were rented. For leases with a term of 12 months or less, the Company makes an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. The Company recognizes lease expenses for such leases on a straight-line basis over the lease term. Operating lease assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The discount rate used to calculate present value is the Company’s incremental borrowing rate or, if available, the rate implicit in the lease. The Company determines the incremental borrowing rate for each lease based primarily on the lease term and the economic environment of the applicable country or region. The discount rate used by the Company for its operating lease was 4.49%. The operating lease right of use assets of $0.4 million as of June 30, 2019 are included in other current assets. The current portion of operating lease liabilities of $0.1 million as of June 30, 2019 is included in other current liabilities and the non-current portion of $0.3 million as of June 30, 2019 is included in other non-current liabilities. The lease expenses recognized for the three months ended June 30, 2019 and 2018 were $4,000 and $4,000, respectively. The lease expenses recognized for the six months ended June 30, 2019 and 2018 were $7,000 and $7,000, respectively. The weighted average remaining lease term was 4 years. The Company does not have finance lease arrangements as of June 30, 2019.
