CHINA XD PLASTICS COMPANY LIMITED AND SUBSIDIARIES

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 – Basis of presentation and 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, 2018 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, 2018, 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 April 15, 2019.

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 March 31, 2019, the results of operations and cash flows for the three-month periods ended March 31, 2019 and 2018, 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 accruals for tax uncertainties and other contingencies, and the discount rate used to determine the present value of the lease payments. The current economic environment has increased the degree of uncertainty inherent in those estimates and assumptions.

(b) Accounting pronouncement adopted in 2019

In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). The new guidance requires the recognition of lease assets and liabilities for operating leases with terms of more than 12 months, in addition to those currently recorded, on the Company’s consolidated balance sheets. Presentation of leases within the consolidated statements of comprehensive income and consolidated statements of cash flows will be generally consistent with the current lease accounting guidance. The Company has adopted this ASU on January 1, 2019 using a modified retrospective approach by recognizing a cumulative-effect adjustment tothe opening balance of retained earnings. This adoption approach resulted in a balance sheet presentation that was not be comparable to the prior period in the first year of adoption. Additionally, the Company used the package of practical expedients that allowed the Company to not reassess: (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases and (3) initial direct costs for any expired or existing leases. The Company also elected the hindsight practical expedient to determine the reasonably certain lease term for existing leases. The adoption of the standard resulted in recognition of right-of-use (“ROU”) assets and lease liabilities of approximately US$16.1 million and US$16.8 million, respectively, as of January 1, 2019. The difference between the initial operating right-of-use asset and operating lease liability of US$0.8 million was accrued rent previously recognized under ASC 840. There was no cumulative effect on retained earnings as of January 1, 2019 as a result of adoption.

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). The new guidance allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. The Company has adopted the standard on January 1, 2019, and there was no material impact on its consolidated financial statements as a result of the adoption.

In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”). The new guidance largely aligns the accounting for share-based awards issued to employees and nonemployees. Existing guidance for employee awards will apply to non-employee share-based transactions with limited exceptions. The new guidance also clarifies that any share based payment awards issued to customers should be evaluated under ASC 606, Revenue from Contracts with Customers. The Company has adopted the standard on January 1, 2019, and there was no material impact on its consolidated financial statements as a result of the adoption.

(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"). The Company's sales are highly concentrated. Sales to distributors individually exceeded 10% of the Company's revenues for the three-month periods ended March 31, 2019 and 2018, are as follows:

	For the Three-Month Period Ended March 31,
	2019					2018
	US$		%			US$		%
Distributor A, located in PRC		56,499,732		18.7	%		47,731,909		15.4	%
Distributor B, located in PRC		33,931,975		11.3	%		29,867,832		9.6	%
Distributor C, located in PRC		32,491,923		10.8	%		35,567,286		11.5	%
Distributor D, located in PRC		21,968,499		7.3	%		32,353,013		10.4	%
Total		144,892,129		48.1	%		145,520,040		46.9	%

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 37.8% (three distributors) and 30.3% (three distributors), of the Company's total raw material purchases for the three-month periods ended March 31, 2019 and 2018, respectively. 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 short-term restricted cash mentioned below maintained at banks consist of the following:

	March 31, 2019		December 31, 2018
	US$		US$
Renminbi (“RMB”) denominated bank deposits with:
Financial Institutions in the PRC		505,806,079		366,773,172
Financial Institutions in Hong Kong Special Administrative Region ("Hong Kong SAR")		8,134		8,134
Financial Institutions in Dubai, UAE		59		-
United States (“U.S.”) dollar denominated bank deposits with:
Financial Institution in the U.S.		6,131		40,390
Financial Institutions in the PRC		17,052		17,050
Financial Institution in Hong Kong SAR		39,299		131,892
Financial Institution in Macau Special Administrative Region ("Macau SAR")		6,095		6,144
Financial Institution in Dubai, UAE		581		14,464
Hong Kong dollar denominated bank deposits with:
Financial institution in Hong Kong SAR		156		156
Dirham denominated bank deposits with:
Financial institution in Dubai, UAE		329,725		438

7

The bank deposits with financial institutions in the PRC are insured by the government authority for up to RMB500,000. The bank deposits with financial institutions in the Hong Kong SAR are insured by the government authority for up to HK$500,000. The bank deposits with financial institutions in the Macau SAR are insured by the government authority for up to MOP$500,000. The bank deposits with financial institutions in the Dubai, UAE are not insured by the government authority. Total bank deposits amounted to $1,509,352 and $1,442,481 are insured as of March 31, 2019 and December 31, 2018, respectively. The Company has not experienced any losses in uninsured bank deposits and does not believe that it is exposed to any significant risks on cash held in bank accounts. 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.

Cash deposits in bank that are restricted as to withdrawal or usage for up to 12 months are reported as restricted cash in the consolidated balance sheets.

Short-term bank deposits that are pledged as collateral for bills payable relating to purchases of raw materials are reported as restricted cash and amounted to US$300,296,989 and US$202,568,664 as of March 31, 2019 and December 31, 2018, respectively. Upon maturity and repayment of the bills payable, which is generally within 6 months, the cash becomes available for use by the Company.

Short-term bank deposits that are related to government grant are reported as restricted cash and amounted to US$1,499,691 and US$1,469,935 as of March 31, 2019 and December 31, 2018, respectively. 

Short-term bank deposits that are pledged as collateral for issuance of letter of guarantee are reported as restricted cash amounted to US$72,250,687 and US$70,885,301 as of March 31, 2019 and December 31, 2018, respectively.

Note 11 – 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 three-month periods ended March 31, 2019 and 2018 were 24.9% and 24.5%, respectively.  The effective income tax rate increased from 24.5% for the three-month period ended March 31, 2018 to 24.9% for the three-month period ended March 31, 2019, primarily due to the decrease of Sichuan Xinda's profit before tax ("PBT") ratio. The effective income tax rate for the three-month period ended March 31, 2019 differs from the PRC statutory income tax rate of 25% primarily due to Sichuan Xinda's preferential income tax rate and  75% additional deduction of R&D expenses of the major PRC operating entities.

As of March 31, 2019, the unrecognized tax benefits were US$34,626,289 and the interest relating to unrecognized tax benefits was US$13,710,137, of which the unrecognized tax benefits in year 2013 amounting to US$3,752,714 and related accrued interest amounting to US$3,164,360 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.

Note 19 - Leases

As discussed in Note 1, effective January 1, 2019, the Company adopted Topic 842. At the inception of a contract, the Company determines if the arrangement is, or contains, a lease. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Rent expense is recognized on a straight-line basis over the lease term.

The Company has made certain accounting policy elections whereby it does not recognize ROU assets or lease liabilities for short-term leases (those with original terms of 12-months or less). All of the Company’s existing leases as of March 31, 2019 were classified as operating leases. As of March 31, 2019, the Company had operating leases for land and office with remaining terms expiring from 2022 through 2037 and a weighted average remaining lease term of 18.01 years. Weighted average discount rate used in the calculation of the lease liabilities was 6.7%. The discount rate reflects the estimated incremental borrowing rate, which includes an assessment of the credit rating to determine the rate that the Company would have to pay to borrow, on a collateralized basis for a similar term, an amount equal to the lease payments in a similar economic environment.

Lease cost for the three-month period ended March 31, 2019 is as follows:

	Three-Month Period Ended March 31,

For the three months ended March 31, 2019, revenue from domestic market decreased by US$14.7 million as a combined result of: a decrease of 11.8% in sales volume; and a depreciation of RMB against USD by 6.5%; partially offset by an increase of 14.3% in the average RMB selling price of our products, as compared with those of last year.

According to the China Association of Automobile Manufacturers, automobile production and sales in China decreased by 9.8% and 11.3%, respectively, for the first quarter of 2019 as compared to the same period of 2018. As weakening in macroeconomic conditions since summer of 2018 continued to exacerbate auto business environment, our domestic sales during the first quarter of 2019 decreased by 4.9% as compared to the same period of the prior year, including 26.9% decrease in Southwest China and 22.0% decrease in East China. 

Thanks to our positive efforts to expand our customer bases and to meet their new requirements, the Company has increased significant growth of 13.6% in North China, and 12.0% in South China,

As for the RMB selling price, the increase of 14.3% was mainly due to more sales of higher-end products such as modified POM and PPO, and sales of new categories of higher-end products of PA66 and PA6 produced with high-priced raw materials for higher selling price in China.

(ii) Overseas market

For the three months ended March 31, 2019, revenues from overseas market was US$5.8 million as compared to US$54,854 of that in 2018.

After a successful trial production at our production base in Dubai in November 2018, the Company has tried to develop new overseas customers besides the existing customer in the Republic of Korea, and has established business relationships with new customers in UAE and India, and shipped products to the end users in Europe. We are optimistic about the prospect of our business expansion overseas.

The Company continued to shift production mix from traditional lower-end products such as PP to higher-end products such as POM and PPO, primarily due to (i) greater growth potential of advanced modified plastics in luxury automobile models in China, (ii) the stronger demand as a result of promotion by the Chinese government for clean energy vehicles and (iii) better quality demand from and consumer recognition of higher-end cars made by automotive manufacturers from Chinese and Germany joint ventures, Sino-U.S. and Sino-Japanese joint ventures, which manufacturers tend to use more and higher-end modified plastics in quantity per vehicle in China.

R&D expenses were US$10.1 million during the quarter ended March 31, 2019 compared with US$5.0 million during the same period in 2018, an increase of US$5.1 million, or 102.0%. This significant increase was primarily due to (i) elevated R&D activities to meet the new higher specification requirements from potential customers, especially overseas; and (ii) increased efforts directed towards applications in new electrical equipment and electronics, alternative energy applications, power devices, aviation equipment and ocean engineering, in addition to other new products primarily for advanced industrialized applications in the automobile sector and in new verticals such as ships, airplanes, high-speed rail, 3D printing materials, biodegradable plastics, and medical devices.

As of March 31, 2019, the number of ongoing research and development projects was 355. We expect to complete and commence to realize economic benefits from approximately 25% of the projects in the near term. The remaining projects are expected to be carried out for a longer period. The majority of the projects are in the field of modified plastics in automotive applications and the rest are in advanced fields such as ships, airplanes, high-speed rail, medical devices, etc.Operating Income

Total operating income was US$31.2 million in the first quarter ended March 31, 2019 compared to $38.9 million in the same period of 2018, representing a decrease of 19.8% or US$7.7 million. This decrease is primarily due to the lower gross margin, higher R&D expenses, partially offset by the lower general & administration expenses and selling expenses.

Income Tax Expense			(3.6	)			(6.2	)			2.6			(41.9	)%

The effective income tax rates for the three-month periods ended March 31, 2019 and 2018 were 24.9% and 24.5%, respectively.  The effective income tax rate increased from 24.5% for the three-month period ended March 31, 2018 to 24.9% for the three-month period ended March 31, 2019, primarily due to the decrease of Sichuan Xinda's profit before tax ("PBT") ratio. The effective income tax rate for the three-month period ended March 31, 2019 differs from the PRC statutory income tax rate of 25% primarily due to Sichuan Xinda's preferential income tax rate and  75% additional deduction of R&D expenses of the major PRC operating entities.

Our PRC and Dubai subsidiaries have US$506.2 million of cash and restricted cash as of March 31, 2019, 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.  

Net Income

As a result of the above factors, we had a net income of US$11.0 million in the first quarter of 2019 compared to a net income of US$19.1 million in the same quarter of 2018.

As of March 31, 2019, we have contractual obligations to pay (i) lease commitments in the amount of US$28.7 million, including US$1.4 million due in one year; (ii) equipment acquisition and facility construction in the amount of US$279.0 million; and (iii) long-term bank loan in the amount of US$386.2 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.

	Three-Month Period Ended March 31,

Operating Activities

Net cash provided by operating activities was US$66.9 million for the three-month period ended March 31, 2019, as compared to US$28.4 million for the three-month period ended March 31, 2018, primarily due to (i) the decrease of approximately US$134.9 million in cash operating payments, including raw material purchases, rental and personnel costs, (ii) the decrease of US$4.8 million in income tax payments (iii) the decrease of US$1.6 million option contracts loss, (iv) the increase of US$0.5 million received from government grant, partially offset by (v) the decrease of approximately US$99.3 million in cash collected from our customers for the three-month period ended March 31, 2019, (v) the increase of US$2.3 million interest payments and (vi) the decrease of US$1.7 million in interest income received.

Investing Activities

Net cash used in the investing activities was US$11.5 million for the three-month period ended March 31, 2019 as compared to US$41.1 million for the same period of last year, mainly due to (i) the decrease of US$163.4 million purchase of time deposits, (ii) the decrease of US$53.0 million purchase of property, plant and equipment and partially offset by (iii) the decrease of US$119.7 million proceeds from maturity of time deposits, (iv) the decrease of US$60.1 million refund of deposit from an equipment supplier and (v) the decrease of US$7.0 million government grant related to the industrial project for 300,000 metric tons biological composite materials.

Financing Activities

Net cash provided by the financing activities was US$76.5 million for the three-month period ended March 31, 2019, as compared to US$96.2 million used in financing activities for the same period of last year, primarily as a result of (i) the increase of the proceeds of US$106.2 million from bank borrowings and (ii) the increase of US$0.3 million interest-free proceeds from related parties, and partially offset by (iii) the decrease of US$66.2 million repayments of bank borrowings.

As of March 31, 2019, our cash and restricted cash balance was US$506.2 million, as compared to US$367.0 million at December 31, 2018.

Days Sales Outstanding ("DSO") has decreased from 84 days for the year ended December 31, 2018 to 67 days for the quarter ended March 31, 2019 as a result of faster accounts receivable collection from the domestic customers.

35

We believe that our DSO is well below industry average Industry Standard Customer and Supplier Payment Terms (days) as below:

	Three-month period ended March 31, 2019	Year ended December 31, 2018
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 178 days for the year ended December 31, 2018 to 253 days for the quarter ended March 31, 2019. Turnover days of payables have decreased from 53 days for the year ended December 31, 2018 to 23 days for the quarter ended March 31, 2019.

Based on past performance and current expectations, we believe our cash and cash equivalents provided by operating activities and financing 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.

Thus the original contracts have been terminated with the amount of RMB2,222.9 million (equivalent to US$330.1 million), and Hailezi agreed to refund the prepayment in the amount of RMB1,704.9 million (equivalent to US$253.2 million) by the end of March 2018, out of the total prepayment made by Sichuan Xinda of RMB1,722.9 million (equivalent to US$255.9 million).

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, cash and cash equivalents, and restricted cash. 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 March 31, 2019 would decrease income before income taxes by approximately US$2.3 million for the quarter ended March 31, 2019. 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.

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 March 31, 2019, the RMB traded at 6.7335 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, 2018.

Notwithstanding management's assessment that our internal control over financial reporting was ineffective as of March 31, 2019. 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 three months ended March 31, 2019 in all material respects.

39

(b) Changes in internal controls.

During the three months ended March 31, 2019, 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; We plan to improve on the above-referenced weakness by the end of the fiscal year ending December 31, 2019.

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 first fiscal quarter ended March 31, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Basis of presentation and significant concentrations and risks

Note 1 – Basis of presentation and 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, 2018 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, 2018, 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 April 15, 2019.

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 March 31, 2019, the results of operations and cash flows for the three-month periods ended March 31, 2019 and 2018, 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 accruals for tax uncertainties and other contingencies, and the discount rate used to determine the present value of the lease payments. The current economic environment has increased the degree of uncertainty inherent in those estimates and assumptions.

(b) Accounting pronouncement adopted in 2019

In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). The new guidance requires the recognition of lease assets and liabilities for operating leases with terms of more than 12 months, in addition to those currently recorded, on the Company’s consolidated balance sheets. Presentation of leases within the consolidated statements of comprehensive income and consolidated statements of cash flows will be generally consistent with the current lease accounting guidance. The Company has adopted this ASU on January 1, 2019 using a modified retrospective approach by recognizing a cumulative-effect adjustment tothe opening balance of retained earnings. This adoption approach resulted in a balance sheet presentation that was not be comparable to the prior period in the first year of adoption. Additionally, the Company used the package of practical expedients that allowed the Company to not reassess: (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases and (3) initial direct costs for any expired or existing leases. The Company also elected the hindsight practical expedient to determine the reasonably certain lease term for existing leases. The adoption of the standard resulted in recognition of right-of-use (“ROU”) assets and lease liabilities of approximately US$16.1 million and US$16.8 million, respectively, as of January 1, 2019. The difference between the initial operating right-of-use asset and operating lease liability of US$0.8 million was accrued rent previously recognized under ASC 840. There was no cumulative effect on retained earnings as of January 1, 2019 as a result of adoption.

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). The new guidance allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. The Company has adopted the standard on January 1, 2019, and there was no material impact on its consolidated financial statements as a result of the adoption.

In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”). The new guidance largely aligns the accounting for share-based awards issued to employees and nonemployees. Existing guidance for employee awards will apply to non-employee share-based transactions with limited exceptions. The new guidance also clarifies that any share based payment awards issued to customers should be evaluated under ASC 606, Revenue from Contracts with Customers. The Company has adopted the standard on January 1, 2019, and there was no material impact on its consolidated financial statements as a result of the adoption.

(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"). The Company's sales are highly concentrated. Sales to distributors individually exceeded 10% of the Company's revenues for the three-month periods ended March 31, 2019 and 2018, are as follows:

	For the Three-Month Period Ended March 31,
	2019					2018
	US$		%			US$		%
Distributor A, located in PRC		56,499,732		18.7	%		47,731,909		15.4	%
Distributor B, located in PRC		33,931,975		11.3	%		29,867,832		9.6	%
Distributor C, located in PRC		32,491,923		10.8	%		35,567,286		11.5	%
Distributor D, located in PRC		21,968,499		7.3	%		32,353,013		10.4	%
Total		144,892,129		48.1	%		145,520,040		46.9	%

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 37.8% (three distributors) and 30.3% (three distributors), of the Company's total raw material purchases for the three-month periods ended March 31, 2019 and 2018, respectively. 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 short-term restricted cash mentioned below maintained at banks consist of the following:

	March 31, 2019		December 31, 2018
	US$		US$
Renminbi (“RMB”) denominated bank deposits with:
Financial Institutions in the PRC		505,806,079		366,773,172
Financial Institutions in Hong Kong Special Administrative Region ("Hong Kong SAR")		8,134		8,134
Financial Institutions in Dubai, UAE		59		-
United States (“U.S.”) dollar denominated bank deposits with:
Financial Institution in the U.S.		6,131		40,390
Financial Institutions in the PRC		17,052		17,050
Financial Institution in Hong Kong SAR		39,299		131,892
Financial Institution in Macau Special Administrative Region ("Macau SAR")		6,095		6,144
Financial Institution in Dubai, UAE		581		14,464
Hong Kong dollar denominated bank deposits with:
Financial institution in Hong Kong SAR		156		156
Dirham denominated bank deposits with:
Financial institution in Dubai, UAE		329,725		438

The bank deposits with financial institutions in the PRC are insured by the government authority for up to RMB500,000. The bank deposits with financial institutions in the Hong Kong SAR are insured by the government authority for up to HK$500,000. The bank deposits with financial institutions in the Macau SAR are insured by the government authority for up to MOP$500,000. The bank deposits with financial institutions in the Dubai, UAE are not insured by the government authority. Total bank deposits amounted to $1,509,352 and $1,442,481 are insured as of March 31, 2019 and December 31, 2018, respectively. The Company has not experienced any losses in uninsured bank deposits and does not believe that it is exposed to any significant risks on cash held in bank accounts. 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.

Cash deposits in bank that are restricted as to withdrawal or usage for up to 12 months are reported as restricted cash in the consolidated balance sheets.

Short-term bank deposits that are pledged as collateral for bills payable relating to purchases of raw materials are reported as restricted cash and amounted to US$300,296,989 and US$202,568,664 as of March 31, 2019 and December 31, 2018, respectively. Upon maturity and repayment of the bills payable, which is generally within 6 months, the cash becomes available for use by the Company.

Short-term bank deposits that are related to government grant are reported as restricted cash and amounted to US$1,499,691 and US$1,469,935 as of March 31, 2019 and December 31, 2018, respectively. 

Short-term bank deposits that are pledged as collateral for issuance of letter of guarantee are reported as restricted cash amounted to US$72,250,687 and US$70,885,301 as of March 31, 2019 and December 31, 2018, respectively.

Note 11 – 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 three-month periods ended March 31, 2019 and 2018 were 24.9% and 24.5%, respectively.  The effective income tax rate increased from 24.5% for the three-month period ended March 31, 2018 to 24.9% for the three-month period ended March 31, 2019, primarily due to the decrease of Sichuan Xinda's profit before tax ("PBT") ratio. The effective income tax rate for the three-month period ended March 31, 2019 differs from the PRC statutory income tax rate of 25% primarily due to Sichuan Xinda's preferential income tax rate and  75% additional deduction of R&D expenses of the major PRC operating entities.

As of March 31, 2019, the unrecognized tax benefits were US$34,626,289 and the interest relating to unrecognized tax benefits was US$13,710,137, of which the unrecognized tax benefits in year 2013 amounting to US$3,752,714 and related accrued interest amounting to US$3,164,360 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.

Leases [Abstract]

Leases

Note 19 - Leases

As discussed in Note 1, effective January 1, 2019, the Company adopted Topic 842. At the inception of a contract, the Company determines if the arrangement is, or contains, a lease. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Rent expense is recognized on a straight-line basis over the lease term.

The Company has made certain accounting policy elections whereby it does not recognize ROU assets or lease liabilities for short-term leases (those with original terms of 12-months or less). All of the Company’s existing leases as of March 31, 2019 were classified as operating leases. As of March 31, 2019, the Company had operating leases for land and office with remaining terms expiring from 2022 through 2037 and a weighted average remaining lease term of 18.01 years. Weighted average discount rate used in the calculation of the lease liabilities was 6.7%. The discount rate reflects the estimated incremental borrowing rate, which includes an assessment of the credit rating to determine the rate that the Company would have to pay to borrow, on a collateralized basis for a similar term, an amount equal to the lease payments in a similar economic environment.

Lease cost for the three-month period ended March 31, 2019 is as follows:

	Three-Month Period Ended March 31,
	2019
	US$
Operating lease cost		423,571
Short-term lease cost		179,195
Total lease cost		602,766

	Remaining Lease Payments US$
2019		1,036,925

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, 2018 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, 2018, 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 April 15, 2019.

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 March 31, 2019, the results of operations and cash flows for the three-month periods ended March 31, 2019 and 2018, 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 accruals for tax uncertainties and other contingencies, and the discount rate used to determine the present value of the lease payments. The current economic environment has increased the degree of uncertainty inherent in those estimates and assumptions.

Accounting Pronouncement Adopted in 2019

(b) Accounting pronouncement adopted in 2019

In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). The new guidance requires the recognition of lease assets and liabilities for operating leases with terms of more than 12 months, in addition to those currently recorded, on the Company’s consolidated balance sheets. Presentation of leases within the consolidated statements of comprehensive income and consolidated statements of cash flows will be generally consistent with the current lease accounting guidance. The Company has adopted this ASU on January 1, 2019 using a modified retrospective approach by recognizing a cumulative-effect adjustment tothe opening balance of retained earnings. This adoption approach resulted in a balance sheet presentation that was not be comparable to the prior period in the first year of adoption. Additionally, the Company used the package of practical expedients that allowed the Company to not reassess: (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases and (3) initial direct costs for any expired or existing leases. The Company also elected the hindsight practical expedient to determine the reasonably certain lease term for existing leases. The adoption of the standard resulted in recognition of right-of-use (“ROU”) assets and lease liabilities of approximately US$16.1 million and US$16.8 million, respectively, as of January 1, 2019. The difference between the initial operating right-of-use asset and operating lease liability of US$0.8 million was accrued rent previously recognized under ASC 840. There was no cumulative effect on retained earnings as of January 1, 2019 as a result of adoption.

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). The new guidance allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. The Company has adopted the standard on January 1, 2019, and there was no material impact on its consolidated financial statements as a result of the adoption.

In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”). The new guidance largely aligns the accounting for share-based awards issued to employees and nonemployees. Existing guidance for employee awards will apply to non-employee share-based transactions with limited exceptions. The new guidance also clarifies that any share based payment awards issued to customers should be evaluated under ASC 606, Revenue from Contracts with Customers. The Company has adopted the standard on January 1, 2019, and there was no material impact on its consolidated financial statements as a result of the adoption.

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"). The Company's sales are highly concentrated. Sales to distributors individually exceeded 10% of the Company's revenues for the three-month periods ended March 31, 2019 and 2018, are as follows:

	For the Three-Month Period Ended March 31,
	2019					2018
	US$		%			US$		%
Distributor A, located in PRC		56,499,732		18.7	%		47,731,909		15.4	%
Distributor B, located in PRC		33,931,975		11.3	%		29,867,832		9.6	%
Distributor C, located in PRC		32,491,923		10.8	%		35,567,286		11.5	%
Distributor D, located in PRC		21,968,499		7.3	%		32,353,013		10.4	%
Total		144,892,129		48.1	%		145,520,040		46.9	%

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 37.8% (three distributors) and 30.3% (three distributors), of the Company's total raw material purchases for the three-month periods ended March 31, 2019 and 2018, respectively. 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.
