CHINA XD PLASTICS COMPANY LIMITED AND SUBSIDIARIES

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 - Basis of presentation, significant concentrations and risks

(a) Basis of presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by rules and regulations of the United States Securities and Exchange Commission ("SEC"). The condensed consolidated balance sheet as of December 31, 2017 was derived from the audited consolidated financial statements of  China XD Plastics Company Limited ("China XD") and subsidiaries (collectively, the "Company"). The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated balance sheet of the Company as of December 31, 2017, and the related consolidated statements of comprehensive income, changes in equity and cash flows for the year then ended, included in the Company's Annual Report on Form 10-K filed with the SEC on March 15, 2018.

In the opinion of the management, all adjustments (which include normal recurring adjustments) necessary to present a fair statement of the financial position as of June 30, 2018, the results of operations and cash flows for the six-month periods ended June 30, 2018 and 2017, have been made.

The preparation of condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the recoverability of the carrying amounts of property, plant and equipment, the realizability of inventories, the useful lives of property, plant and equipment, the collectability of accounts receivable, the fair values of stock-based compensation awards, and the accruals for tax uncertainties and other contingencies. The current economic environment has increased the degree of uncertainty inherent in those estimates and assumptions.

(b) Accounting Pronouncement Adopted in 2018

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers, which supersedes virtually all existing revenue recognition guidance. The new standard requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. This update also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. We adopted ASU 2014-09 in the first quarter 2018, using the modified retrospective transition approach, which did not have any material impact on how we recognize revenue or to our financial statements or disclosures. See below for additional information related to our recognition of revenue generated from customer contracts.

Revenue recognition

Effective January 1, 2018, we adopted the new guidance of ASC Topic 606, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition. Topic 606 requires us to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance requires us to apply the following steps: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, we satisfy a performance obligation. The adoption of this new guidance did not result in any changes to our revenue recognition practice.

ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash requires that the Statement of Cash Flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Company retrospectively adopted this guidance as of January 1, 2018, to each period presented.

(c) Significant concentrations and risks

Sales concentration

The Company sells its products primarily through approved distributors in the People's Republic of China (the "PRC"). To a lesser extent, the Company also sells its products to an overseas customer in the Republic of Korea (the "ROK"). The Company's sales are highly concentrated.  Sales to distributors and end customer individually exceeded 10% of the Company's revenues for the three-month and six-month periods ended June 30, 2018 and 2017, are as follows:

	Three-Month Period Ended June 30,
	2018					2017
	US$		%			US$		%
Distributor A, located in PRC		44,765,278		14.1	%		41,816,369		13.3	%
Distributor B, located in PRC		41,215,145		13.0	%		35,410,723		11.3	%
Distributor C, located in PRC		38,366,592		12.1	%		29,450,243		9.4	%
Direct Customer D, located in ROK		-		0.0	%		32,956,525		10.5	%
Total		124,347,015		39.2	%		139,633,860		44.5	%

	Six-Month Period Ended June 30,
	2018					2017
	US$		%			US$		%
Distributor A, located in PRC		92,497,187		14.7	%		84,034,202		15.2	%
Distributor B, located in PRC		76,782,431		12.2	%		63,921,050		11.6	%
Distributor C, located in PRC		70,719,605		11.3	%		51,681,940		9.4	%
Total		239,999,223		38.2	%		199,637,192		36.2	%

The Company expects revenues from these distributors to continue to represent a substantial portion of its revenue in the future. Any factor adversely affecting the automobile industry in the PRC or the business operations of these customers will have a material effect on the Company's business, financial position and results of operations.

Purchase concentration of raw materials and equipment

The principal raw materials used for the Company's production of modified plastics products are plastic resins, such as polypropylene, ABS and nylon. The Company purchases substantially all of its raw materials through a limited number of distributors.  Raw material purchases from these distributors, which individually exceeded 10% of the Company's total raw material purchases, accounted for approximately 20.5% (two distributors) and 71.1% (six distributors) for the three-month periods ended June 30, 2018 and 2017, respectively, and 10.0% (one distributor) and 60.0% (five distributors) of the Company's total raw materials purchases for the six-month periods ended June 30, 2018 and 2017, respectively of the Company's total raw material purchases, Management believes that other suppliers could provide similar raw materials on comparable terms. A change in suppliers, however, could cause a delay in manufacturing and a possible loss of sales, which would adversely affect the Company's business, financial position and results of operations.

	June 30, 2018		December 31, 2017

To limit exposure to credit risk, the Company primarily places bank deposits with large financial institutions in the PRC, Hong Kong SAR, Macau SAR and Dubai, UAE with acceptable credit rating.

The effective income tax rates for the six-month periods ended June 30, 2018 and 2017 were 20.2% and 16.8%, respectively.  The effective income tax rate increased from 16.8% for the six-month period ended June 30, 2017 to 20.2% for the six-month period ended June 30, 2018, primarily due to the increase of continuous operating losses occurred in overseas subsidiaries such as Dubai Xinda and Xinda Holding (HK), the decrease of 50% additional deduction of R&D expense and partially offset by the increase of Sichuan Xinda’s profit before tax (“PBT”) percentage within the consolidating entities. The effective income tax rate for the six-month period ended June 30, 2018 differs from the PRC statutory income tax rate of 25% primarily due to Sichuan Xinda's preferential income tax rate, the reversal of the unrecognized tax benefits accrued in year 2012 and 50% additional deduction of R&D expenses of the major PRC operating entities.

US$2,898,304 previously unrecognized tax benefits accrued in year 2012 and the related accrued interest amounting to US$ 2,721,753 were reversed due to the expiration of five-year tax assessment period on May 31, 2018. As of June 30, 2018, the unrecognized tax benefits were US$35,306,965 and the interest relating to unrecognized tax benefits was US$9,973,520, of which the unrecognized tax benefits in year 2013 amounting to US$3,819,016 and related accrued interest amounting to US$2,721,430 were classified as current liabilities as the five-year tax assessment period will expire on May 31, 2019. No penalties expense related to unrecognized tax benefits were recorded. The Company is currently unable to provide an estimate of a range of the total amount of unrecognized tax benefits that is reasonably possible to change significantly within the next twelve months.

The Company has also received RMB45 million (equivalent to US$6.8 million) from Harbin Bureau of Finance for Biomedical composites project as of June 30, 2018.

Since the funding is related to the construction of long-term assets, the amounts were recognized as government grant, which is included in deferred income on the condensed consolidated balance sheets, and to be recognized as other income in the condensed consolidated statements of comprehensive income over the periods and in the proportions in which depreciation expense on the long-term assets is recognized.

The Sichuan factory has been operational since July 2016. A cumulative RMB54.9 million (equivalent to US$8.3 million) government grants have been amortized as other income proportionate to the depreciation of the related assets, of which RMB15.6 million (equivalent to US$2.5 million) was amortized in the six-month period ended June 30, 2018.

As of June 30, 2018, in Harbin, Heilongjiang Province, we had approximately 290,000 metric tons of production capacity across 64 automatic production lines utilizing German twin-screw extruding systems, automatic weighing systems and Taiwanese conveyer systems. In December 2013, we broke ground on the construction of our fourth production plant in Nanchong City, Sichuan Province, with additional 300,000 metric tons of annual production capacity, expecting to bring total domestic installed production capacity to 690,000 metric tons with additional 70 new production lines at the completion of the construction of our fourth production plant. Sichuan Xinda has supplied to its customers since 2013. We installed 50 production lines in the second half of 2016 in our Sichuan plant with production capacity of 216,000 metric tons during the year of 2017.  As of June 30, 2018, there is still construction ongoing on the site of our Sichuan plant which is to be expected to be completed by the end of the September of 2018. In order to meet the increasing demand from our customer in the ROK and to develop potential overseas markets, Dubai Xinda obtained one leased property and two purchased properties, approximately 52,530 square meters in total, including one leased 10,000 square meters, and two purchased 20,206 and 22,324 square meters on January 25, 2015, June 28, 2016 and September 21, 2016, respectively, from Jebel Ali Free Zone Authority ("JAFZA") in Dubai, UAE, with constructed building comprising warehouses, offices and service blocks.

According to the China Association of Automobile Manufacturers, automobile production and sales in China increased by 4.15% and 5.57%, respectively, for the first half year of 2018 as compared to the same period of 2017.

An improvement in macroeconomic conditions since 2017 has improved business conditions and ease pricing pressures.

Driven by accelerating growth of 1.5% in Northeast China, 120.8% in Central China, 111.0% in South China, 52.1% in Southwest China, 1.0% in North China, and 1.7% in East China, our domestic sales during the three months ended June 30, 2018 increased by 13.0%, as compared to the same period of the prior year.

As for the RMB selling price, the increase was mainly due to more sales of higher-end products of modified PA66, PLA and PPO in China.

(ii) Overseas market

For the three months ended June 30, 2018, revenues from overseas market was US$53,353 as compared to US$33.0 million of that in 2017.

The Company has tried to develop new customers overseas besides the existing ROK customer.  The sales with this ROK customer was suspended due to the accounts receivable balance overdue situation.  As of June 30, 2018, the ROK customer has an outstanding balance of US$46.6 million, among which balance of US$10.2 million was overdue for less than 3 months, US$32.4 million was 3-6 month past due, US$4.0 million was overdue for 7-12 month past due.  The ROK customer expected to pay off the outstanding balance by September 2018.  As the accounts receivable balance was overdue, the Company suspended sales to the ROK customer in 2018.

The effective income tax rates for the three-month periods ended June 30, 2018 and 2018 were 16.8% and 12.8%, respectively. The increase of effective income tax rate was primarily due to increase of continuous operating losses occurred in overseas subsidiaries such as Dubai Xinda and Xinda Holding (HK), the decrease of 50% additional deduction of R&D expense and partially offset by the increase of Sichuan Xinda’s PBT percentage within the consolidating entities. The effective income tax rate for the three-month ended June 30, 2018 differs from the PRC statutory income tax rate of 25% primarily due to Sichuan Xinda's preferential income tax rate, the reversal of the unrecognized tax benefits accrued in year 2012 and 50% additional deduction of R&D expenses of the major PRC operating entities.

Our PRC and Dubai subsidiaries have US$447.3 million of cash and cash equivalents, restricted cash and time deposits as of June 30, 2018, which are planned to be indefinitely reinvested in the PRC and Dubai. Due to our policy of indefinitely reinvesting our earnings in our PRC business, we have not provided for deferred income tax liabilities related to PRC withholding income tax on undistributed earnings of our PRC subsidiaries. In addition, due to our policy of indefinitely reinvesting our earnings in Dubai, UAE, we have not provided for deferred income tax liabilities related to Dubai Xinda in Dubai, UAE, on undistributed earnings.

Inventories increased by 30.4% as a result of more purchases of the raw materials and the Company's strategy to stock up the finished goods for the upcoming order.  Prepaid expenses and other current assets decreased by 41.0% or US$59.1 million as Sichuan Xinda received the refund of prepayment from Hailezi in January 2018. Prepayments to equipment and construction suppliers increased by 166.2% or US$316.7 million because HLJ Xinda Group prepaid to Hailezi to purchase equipment for the industrial project of upgrading existing equipment for 300,000 metric tons of biological based composite material and 100,000 metric tons of engineering plastics and Sichuan Xinda prepaid to Hailezi to purchase equipment for the production of 300,000 metric tons of bio-composite materials. The aggregate short-term and long-term bank loans decreased by 13.7% due to the repayments of the loans. We define the manageable debt level as the sum of aggregate short-term and long-term loans, and notes payable over total assets.

LIQUIDITY AND CAPITAL RESOURCES

Historically, our primary uses of cash have been to finance working capital needs and capital expenditures for new production lines. We have financed these requirements primarily from cash generated from operations, bank borrowings and the issuance of our convertible preferred stocks and debt financings. As of June 30, 2018 and December 31, 2017, we had US$449.4 million and US$608.1 million, respectively, in the total amount of cash and cash equivalents, restricted cash and time deposits, which were primarily deposited with banks in China (including Hong Kong and Macau SAR), UAE and U.S. As of June 30, 2018, we had US$635.5 million outstanding short-term bank loans (including the current portion of long-term bank loans), including US$322.2 million unsecured loan and US$68.0 million loans secured by accounts receivable, US$69.5 million loans secured by restricted cash, and US$175.8 long-term bank loans that due in one year. We also had US$132.3 million unsecured long-term loans (excluding the current portion). Short-term and long-term bank loans in total bear a weighted average interest rate of 4.4% per annum and do not contain any renewal terms. We have historically been able to make repayments when due.

We have historically been able to make repayments when due. As of June 30, 2018, we have contractual obligations to pay (i) lease commitments in the amount of US$29.9 million, including US$1.6 million due in one year; (ii) equipment acquisition and facility construction in the amount of US$344.6 million; and (iii) long-term bank loan in the amount of US$335.9 million (including principals and interests).

We expect that we will be able to meet our needs to fund operations, capital expenditures and other commitments in the next 12 months primarily with our cash and cash equivalents, operating cash flows and bank borrowings. 

We may, however, require additional cash resources due to changes in business conditions or other future developments. If these sources are insufficient to satisfy our cash requirements, we may seek to sell additional equity or debt securities or obtain a credit facility. The sale of additional equity or equity-linked securities could result in additional dilution to stockholders. The incurrence of indebtedness would result in increased debt service obligations and could result in operating and financial covenants that would restrict operations. Financing may not be available in amounts or on terms acceptable to us, or at all.

The following table sets forth a summary of our cash flows for the periods indicated.

	Six-Month Period Ended June 30,
(in millions US$)	2018			2017
Net cash provided by operating activities		152.6			166.6
Net cash used in investing activities		(90.0	)		(176.3	)
Net cash (used in) provided by financing activities		(41.2	)		130.1
Effect of foreign currency exchange rate changes on cash, cash equivalents and restricted cash		(5.5	)		8.0
Net increase in cash, cash equivalents, and restricted cash		15.9			128.4
Cash, cash equivalents, and restricted cash at the beginning of period		320.1			271.6
Cash, cash equivalents, and restricted cash at the end of period		336.0			400.0

Operating Activities

Net cash provided by operating activities was US$152.6 million for the six-month period ended June 30, 2018, as compared to US$166.6 million provided in operating activities for the six-month period ended June 30, 2017, due to (i) the decrease of approximately US$140.6 million in cash collected from our customers for the six-month period ended June 30, 2018, (ii) the increase of US$5.4 million in income tax payments for the six-month period ended June 30, 2018, (iii) the increase of US$1.6 million option contracts loss and (iv) the increase of US$5.9 million interest payments, partially offset by (v) the decrease of approximately US$139.1 million in cash operating payments, including raw material purchases, rental and personnel costs and (vi) the increase of US$0.4 million received from government grant.

Investing Activities

Net cash used in the investing activities was US$90.0 million for the six-month period ended June 30, 2018 as compared to US$176.3 million for the same period of last year, due to (i) the increase of US$143.3 million proceeds from maturity of time deposits, (ii) the increase of US$3.5 million government grant, (iii) the decrease of US$6.2 million acquisition of land use right, (iv) the decrease of US$5.2 million purchase of time deposits, partially offset by (v) the increase of US$53.2 million purchase of property, plant and equipment, (vi) the decrease of US$15.1 million refund of deposit from an equipment supplier and the increase of US$3.6 million deposits for acquisition of equity.

Financing Activities

Net cash used in the financing activities was US$41.2 million for the six-month period ended June 30, 2018, as compared to US$130.1 million provided by financing activities for the same period of last year, primarily as a result of (i) the increase of US$275.9 million repayments of bank borrowings for the three-month period ended June 30, 2018, partially offset by (ii) the increase of the proceeds of US$29.0 million from bank borrowings and (iii) the increase of US$75.6 million in investment received in advance from a related party.

As of June 30, 2018, our cash, cash equivalents and restricted cash balance was US$336.0 million, as compared to US$320.1 million at December 31, 2017.

Days Sales Outstanding ("DSO") has decreased from 99 days for the year ended December 31, 2017 to 87 days for the six-month period ended June 30, 2018 as a result of faster accounts receivable collection from the domestic customers.

It takes shorter to collect from our customers. We believe that our DSO is well below industry average Industry Standard Customer and Supplier Payment Terms (days) as below:

	Six-month period ended June 30, 2018	Year ended December 31, 2017
Customer Payment Term	Payment in advance/up to 90 days	Payment in advance/up to 90 days
Supplier Payment Term	Payment in advance/up to 90 days	Payment in advance/up to 90 days

Inventory turnover days have increased from 120 days for the year ended December 31, 2017 to 169 days for the six-month period ended June 30, 2018. Turnover days of payables have decreased from 94 days for the year ended December 31, 2017 to 69 days for the six-month period ended June 30, 2018.

Based on past performance and current expectations, we believe our cash and cash equivalents provided by operating activities will satisfy our working capital needs, capital expenditures and other liquidity requirements associated with our operations for at least the next 12 months.

The majority of the Company's revenues and expenses were denominated primarily in Renminbi ("RMB"), the currency of the People's Republic of China. There is no assurance that exchange rates between the RMB and the U.S. Dollar will remain stable.  Inflation has not had a material impact on the Company's business.

Off-Balance Sheet Arrangements

We have not engaged in any off-balance sheet transactions.

Item 3. Quantitative and Qualitative Disclosures about Market Risks

Interest Rate Risk

We are exposed to interest rate risk primarily with respect to our short-term loans, long-term bank loans, notes payable, cash and cash equivalents, restricted cash and time deposits. Although the interest rates, which are based on the banks' prime rates are fixed for the terms of the loans and deposits, increase in interest rates will increase our interest expense.

A hypothetical 1.0% increase in the annual interest rate for all of our credit facilities under which we had outstanding borrowings as of June 30, 2018 would decrease income before income taxes by approximately US$3.8 million for the six-month period ended June 30, 2018. Management monitors the banks' prime rates in conjunction with our cash requirements to determine the appropriate level of debt balances relative to other sources of funds. We have not entered into any hedging transactions in an effort to reduce our exposure to interest rate risk.

31

Foreign Currency Exchange Rates

The majority of our revenues are collected in and our expenses are paid in RMB. We face foreign currency rate translation risks when our results are translated to U.S. dollars.

The RMB was relatively stable against the U.S. dollar at approximately 8.28 RMB to the US$1.00 until July 21, 2005 when the Chinese currency regime was altered resulting in a 2.1% revaluation versus the U.S. dollar. From July 21, 2005 to June 30, 2010, the RMB exchange rate was no longer linked to the U.S. dollar but rather to a basket of currencies with a 0.3% margin of fluctuation resulting in further appreciation of the RMB against the U.S. dollar. Since June 30, 2009, the exchange rate had remained stable at 6.8307 RMB to 1.00 U.S. dollar until June 30, 2010 when the People's Bank of China allowed a further appreciation of the RMB by 0.43% to 6.798 RMB to 1.00 U.S. dollar. The People's Bank of China allowed the RMB and U.S. dollar exchange rate to fluctuate within 1% on April 16, 2012 and 2% on March 17, 2014, respectively. On June 30, 2018, the RMB traded at 6.6166 RMB to 1.00 U.S. dollar.

There remains international pressure on the Chinese government to adopt an even more flexible currency policy and the exchange rate of RMB is subject to changes in China's government policies which are, to a large extent, dependent on the economic and political development both internationally and locally and the demand and supply of RMB in the domestic market. There can be no assurance that such exchange rate will continue to remain stable in the future amongst the volatility of currencies, globalization and the unstable economies in recent years. Since (i) our revenues and net income of our PRC operating entities are denominated in RMB, and (ii) the payment of dividends, if any, will be in U.S. dollars, any decrease in the value of RMB against U.S. dollars would adversely affect the value of the shares and dividends payable to shareholders, in U.S. dollars.

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

The Company's management has evaluated, under the supervision and with the participation of the Company's Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operations of the Company's disclosure controls and procedures (as defined in Securities Exchange Act Rule 13a-15(e)), as of the end of the period covered by this report. Based on that evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were not effective because of material weakness in our internal control over financial reporting as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

Notwithstanding management's assessment that our internal control over financial reporting was ineffective as of June 30, 2018. We believe that our unaudited condensed consolidated financial statements included in this Quarterly Report present fairly our financial position, results of operations and cash flows for the six-month period ended June 30, 2018 in all material respects.

(b) Changes in internal controls.

During the six-month period ended June 30, 2018 , our efforts to improve our internal controls over financial reporting 1) adopting procedures to evaluate and assess performance of directors, officers and employees of the Company, (2) internal meetings, discussions, trainings and seminars periodically to review and improve our internal control procedures; (3) recruiting qualified accounting staff in Xinda CI (Beijing) with requisite expertise and knowledge to help improve our internal control procedures. We plan to improve on the above-referenced weakness by the end of the fiscal year ending December 31, 2018.

Other than the foregoing, there has been no other changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during our six-month period ended June 30, 2018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Basis of presentation, significant concentrations and risks [Abstract]

Basis of presentation, significant concentrations and risks

Note 1 - Basis of presentation, significant concentrations and risks

(a) Basis of presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by rules and regulations of the United States Securities and Exchange Commission ("SEC"). The condensed consolidated balance sheet as of December 31, 2017 was derived from the audited consolidated financial statements of  China XD Plastics Company Limited ("China XD") and subsidiaries (collectively, the "Company"). The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated balance sheet of the Company as of December 31, 2017, and the related consolidated statements of comprehensive income, changes in equity and cash flows for the year then ended, included in the Company's Annual Report on Form 10-K filed with the SEC on March 15, 2018.

In the opinion of the management, all adjustments (which include normal recurring adjustments) necessary to present a fair statement of the financial position as of June 30, 2018, the results of operations and cash flows for the six-month periods ended June 30, 2018 and 2017, have been made.

The preparation of condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the recoverability of the carrying amounts of property, plant and equipment, the realizability of inventories, the useful lives of property, plant and equipment, the collectability of accounts receivable, the fair values of stock-based compensation awards, and the accruals for tax uncertainties and other contingencies. The current economic environment has increased the degree of uncertainty inherent in those estimates and assumptions.

b) Accounting Pronouncement Adopted in 2018

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers, which supersedes virtually all existing revenue recognition guidance. The new standard requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. This update also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. We adopted ASU 2014-09 in the first quarter 2018, using the modified retrospective transition approach, which did not have any material impact on how we recognize revenue or to our financial statements or disclosures. See below for additional information related to our recognition of revenue generated from customer contracts.

Revenue recognition

Effective January 1, 2018, we adopted the new guidance of ASC Topic 606, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition. Topic 606 requires us to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance requires us to apply the following steps: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, we satisfy a performance obligation. The adoption of this new guidance did not result in any changes to our revenue recognition practice.

ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash requires that the Statement of Cash Flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Company retrospectively adopted this guidance as of January 1, 2018, to each period presented.

(c) Significant concentrations and risks

Sales concentration

The Company sells its products primarily through approved distributors in the People's Republic of China (the "PRC"). To a lesser extent, the Company also sells its products to an overseas customer in the Republic of Korea (the "ROK"). The Company's sales are highly concentrated.  Sales to distributors and end customer individually exceeded 10% of the Company's revenues for the three-month and six-month periods ended June 30, 2018 and 2017, are as follows:

	Three-Month Period Ended June 30,
	2018					2017
	US$		%			US$		%
Distributor A, located in PRC		44,765,278		14.1	%		41,816,369		13.3	%
Distributor B, located in PRC		41,215,145		13.0	%		35,410,723		11.3	%
Distributor C, located in PRC		38,366,592		12.1	%		29,450,243		9.4	%
Direct Customer D, located in ROK		-		0.0	%		32,956,525		10.5	%
Total		124,347,015		39.2	%		139,633,860		44.5	%

	Six-Month Period Ended June 30,
	2018					2017
	US$		%			US$		%
Distributor A, located in PRC		92,497,187		14.7	%		84,034,202		15.2	%
Distributor B, located in PRC		76,782,431		12.2	%		63,921,050		11.6	%
Distributor C, located in PRC		70,719,605		11.3	%		51,681,940		9.4	%
Total		239,999,223		38.2	%		199,637,192		36.2	%

The Company expects revenues from these distributors to continue to represent a substantial portion of its revenue in the future. Any factor adversely affecting the automobile industry in the PRC or the business operations of these customers will have a material effect on the Company's business, financial position and results of operations.

Purchase concentration of raw materials and equipment

The principal raw materials used for the Company's production of modified plastics products are plastic resins, such as polypropylene, ABS and nylon. The Company purchases substantially all of its raw materials through a limited number of distributors.  Raw material purchases from these distributors, which individually exceeded 10% of the Company's total raw material purchases, accounted for approximately 20.5% (two distributors) and 71.1% (six distributors) for the three-month periods ended June 30, 2018 and 2017, respectively, and 10.0% (one distributor) and 60.0% (five distributors) of the Company's total raw materials purchases for the six-month periods ended June 30, 2018 and 2017, respectively of the Company's total raw material purchases, Management believes that other suppliers could provide similar raw materials on comparable terms. A change in suppliers, however, could cause a delay in manufacturing and a possible loss of sales, which would adversely affect the Company's business, financial position and results of operations.

Cash concentration

Cash and cash equivalents, short-term restricted cash and time deposits mentioned below maintained at banks consist of the following:

	June 30, 2018		December 31, 2017

Income tax

Note 12 – Income tax

Pursuant to an approval from the local tax authority in July 2013, Sichuan Xinda, a subsidiary of China XD, became a qualified enterprise located in the western region of the PRC, which entitled it to a preferential income tax rate of 15% from January 1, 2013 to December 31, 2020. Under the current laws of Dubai, Dubai Xinda, a subsidiary of China XD, is exempted from income taxes.

The effective income tax rates for the six-month periods ended June 30, 2018 and 2017 were 20.2% and 16.8%, respectively.  The effective income tax rate increased from 16.8% for the six-month period ended June 30, 2017 to 20.2% for the six-month period ended June 30, 2018, primarily due to the increase of continuous operating losses occurred in overseas subsidiaries such as Dubai Xinda and Xinda Holding (HK), the decrease of 50% additional deduction of R&D expense and partially offset by the increase of Sichuan Xinda’s profit before tax (“PBT”) percentage within the consolidating entities. The effective income tax rate for the six-month period ended June 30, 2018 differs from the PRC statutory income tax rate of 25% primarily due to Sichuan Xinda's preferential income tax rate, the reversal of the unrecognized tax benefits accrued in year 2012 and 50% additional deduction of R&D expenses of the major PRC operating entities.

US$2,898,304 previously unrecognized tax benefits accrued in year 2012 and the related accrued interest amounting to US$ 2,721,753 were reversed due to the expiration of five-year tax assessment period on May 31, 2018. As of June 30, 2018, the unrecognized tax benefits were US$35,306,965 and the interest relating to unrecognized tax benefits was US$9,973,520, of which the unrecognized tax benefits in year 2013 amounting to US$3,819,016 and related accrued interest amounting to US$2,721,430 were classified as current liabilities as the five-year tax assessment period will expire on May 31, 2019. No penalties expense related to unrecognized tax benefits were recorded. The Company is currently unable to provide an estimate of a range of the total amount of unrecognized tax benefits that is reasonably possible to change significantly within the next twelve months.

Basis of presentation, significant concentrations and risks [Abstract]

Basis of presentation

(a) Basis of presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by rules and regulations of the United States Securities and Exchange Commission ("SEC"). The condensed consolidated balance sheet as of December 31, 2017 was derived from the audited consolidated financial statements of  China XD Plastics Company Limited ("China XD") and subsidiaries (collectively, the "Company"). The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated balance sheet of the Company as of December 31, 2017, and the related consolidated statements of comprehensive income, changes in equity and cash flows for the year then ended, included in the Company's Annual Report on Form 10-K filed with the SEC on March 15, 2018.

In the opinion of the management, all adjustments (which include normal recurring adjustments) necessary to present a fair statement of the financial position as of June 30, 2018, the results of operations and cash flows for the six-month periods ended June 30, 2018 and 2017, have been made.

The preparation of condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the recoverability of the carrying amounts of property, plant and equipment, the realizability of inventories, the useful lives of property, plant and equipment, the collectability of accounts receivable, the fair values of stock-based compensation awards, and the accruals for tax uncertainties and other contingencies. The current economic environment has increased the degree of uncertainty inherent in those estimates and assumptions.

Accounting Pronouncement Adopted in 2018

b) Accounting Pronouncement Adopted in 2018

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers, which supersedes virtually all existing revenue recognition guidance. The new standard requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. This update also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. We adopted ASU 2014-09 in the first quarter 2018, using the modified retrospective transition approach, which did not have any material impact on how we recognize revenue or to our financial statements or disclosures. See below for additional information related to our recognition of revenue generated from customer contracts.

Revenue recognition

Effective January 1, 2018, we adopted the new guidance of ASC Topic 606, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition. Topic 606 requires us to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance requires us to apply the following steps: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, we satisfy a performance obligation. The adoption of this new guidance did not result in any changes to our revenue recognition practice.

ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash requires that the Statement of Cash Flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Company retrospectively adopted this guidance as of January 1, 2018, to each period presented.

Significant concentrations and risks

(c) Significant concentrations and risks

Sales concentration

The Company sells its products primarily through approved distributors in the People's Republic of China (the "PRC"). To a lesser extent, the Company also sells its products to an overseas customer in the Republic of Korea (the "ROK"). The Company's sales are highly concentrated.  Sales to distributors and end customer individually exceeded 10% of the Company's revenues for the three-month and six-month periods ended June 30, 2018 and 2017, are as follows:

	Three-Month Period Ended June 30,

Distributor A, located in PRC		92,497,187		14.7	%		84,034,202		15.2	%
Distributor B, located in PRC		76,782,431		12.2	%		63,921,050		11.6	%
Distributor C, located in PRC		70,719,605		11.3	%		51,681,940		9.4	%
Total		239,999,223		38.2	%		199,637,192		36.2	%

The Company expects revenues from these distributors to continue to represent a substantial portion of its revenue in the future. Any factor adversely affecting the automobile industry in the PRC or the business operations of these customers will have a material effect on the Company's business, financial position and results of operations.

Purchase concentration of raw materials and equipment

The principal raw materials used for the Company's production of modified plastics products are plastic resins, such as polypropylene, ABS and nylon. The Company purchases substantially all of its raw materials through a limited number of distributors.  Raw material purchases from these distributors, which individually exceeded 10% of the Company's total raw material purchases, accounted for approximately 20.5% (two distributors) and 71.1% (six distributors) for the three-month periods ended June 30, 2018 and 2017, respectively, and 10.0% (one distributor) and 60.0% (five distributors) of the Company's total raw materials purchases for the six-month periods ended June 30, 2018 and 2017, respectively of the Company's total raw material purchases, Management believes that other suppliers could provide similar raw materials on comparable terms. A change in suppliers, however, could cause a delay in manufacturing and a possible loss of sales, which would adversely affect the Company's business, financial position and results of operations.

Due to a redesign of outdoor storage facility in June 2017, HLJ Xinda Group entered into a supplementary agreement with Hailezi, which decreased the original contract amount to RMB283.7 million (equivalent to US$42.9 million).
