1. Organization and basis of presentation

The consolidated financial statements include the financial statements of Highpower International, Inc.

Highpower and its subsidiaries are collectively referred to as the "Company".

Highpower was incorporated in the State of Delaware on January 3, 2006. HKHTC was incorporated in Hong Kong on July 4, 2003. All other subsidiaries are incorporated in the People’s Republic of China (“PRC”).

On May 15, 2013, GZ Highpower increased its paid-in capital from RMB15,000,000 ($2,381,293) to RMB30,000,000 ($4,807,847). On November 13, 2014, GZ Highpower increased its paid-in capital from RMB30,000,000 ($4,898,119) to RMB40,000,000 ($6,530,825) and the additional capital of RMB10,000,000 was contributed by SZ Highpower. As of March 31, 2016, SZ Highpower holds 70% of the equity interest of GZ Highpower, and four founding management members of GZ Highpower hold the remaining 30%.

In April 2014, the Company and certain institutional investors entered into a securities purchase agreement, pursuant to which the Company sold 1,000,000 shares of common stock and warrants exercisable for 500,000 shares of common stock in a registered direct offering at a price of $5.05 per fixed combination for aggregate proceeds of $5.05 million. The shares and warrants were sold in multiples of a fixed combination consisting of (i) one share of common stock and (ii) one immediately exercisable warrant to purchase 0.50 shares of common stock.

2. Summary of significant accounting policies

Basis of presentation

The accompanying consolidated balance sheet as of December 31, 2015, which has been derived from audited financial statements, and the unaudited interim consolidated financial statements as of March 31, 2016 and for the three ended March 31, 2016 and 2015 have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and disclosures, which are normally included in financial statements prepared in accordance with United States generally accepted accounting principles (U.S. GAAP), have been condensed or omitted pursuant to such rules and regulations. The interim financial information should be read in conjunction with the Financial Statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, previously filed with the SEC on March 29, 2016.

In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present a fair presentation of the Company’s consolidated financial position as of March 31, 2016, its consolidated results of operations and cash flows for the three months ended March 31, 2016 and 2015, as applicable, have been made. The interim results of operations are not necessarily indicative of the operating results for the full fiscal year or any future periods.

Principles of consolidation

The consolidated financial statements include the accounts of Highpower and its subsidiaries. All significant inter-company accounts and transactions have been eliminated in consolidation. Non-controlling interests represent the equity interest in the GZ Highpower that is not attributable to the Company.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant items subject to such estimates and assumptions include revenues; the allowance for doubtful receivables; recoverability of the carrying amount of inventory; fair values of financial instruments; and the assessment of deferred tax assets or liabilities. These estimates are often based on complex judgments and assumptions that management believes to be reasonable but are inherently uncertain and unpredictable. Actual results could differ significantly from these estimates.

2. Summary of significant accounting policies (continued)

Concentrations of credit risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of accounts receivable. The Company extends credit based on an evaluation of the customer’s financial condition, generally without requiring collateral or other security. In order to minimize the credit risk, the management of the Company has delegated a team responsible for determining credit limits, credit approvals and other monitoring procedures to ensure that follow-up action is taken to recover overdue debts. Further, the Company reviews the recoverable amount of each individual trade debt at each balance sheet date to ensure that adequate impairment losses are made for irrecoverable amounts. In this regard, the management of the Company considers that the Company’s credit risk is significantly reduced.

No customer accounted for 10% or more of total sales during the three months ended March 31, 2016 and 2015.

There was one major supplier that accounted for 14.4% of the total purchase amount during the three months ended March 31, 2016. And no supplier accounted for 10% or more of the total purchase amount during the three months ended March 31, 2015.

There was one major customer that accounted for 11.5% and 11.3% of the accounts receivable as of March 31, 2016 and December 31, 2015, respectively.

Cash

Cash include all cash and deposits in banks with initial maturities of three months or less.

Restricted cash

Restricted cash include time deposits and cash security for bank acceptance bills included in notes payable.

Accounts receivable

Accounts receivable are stated at the original amount less an allowance for doubtful receivables, if any, based on a review of all outstanding amounts at period end. An allowance is also made when there is objective evidence that the Company will not be able to collect all amounts due according to the original terms of the receivables. Bad debts are written off against the allowance after all collection efforts have ceased. The Company extends unsecured credit to customers in the normal course of business and believes all accounts receivable in excess of the allowances for doubtful receivables to be fully collectible. The Company does not accrue interest on trade accounts receivable.

Notes receivable

Notes receivable represent banks’ and commercial acceptances that have been arranged with third-party financial institutions by certain customers to settle their purchases from us. These banks’ acceptances are non-interest bearing and are collectible within one year.

2. Summary of significant accounting policies (continued)

Inventories

Inventories are stated at lower of cost or market. Cost is determined using the weighted average method. Inventory includes raw materials, packing materials, consumables, work in progress and finished goods. The variable production overhead is allocated to each unit of production on the basis of the actual use of the production facilities. The allocation of fixed production overhead to the costs of conversion is based on the normal capacity of the production facilities.

Property, plant and equipment

Property, plant and equipment, net are stated at cost less accumulated depreciation. Cost represents the purchase price of the asset and other costs incurred to bring the asset into its existing use. Maintenance, repairs and betterments, including replacement of minor items, are charged to expense; major additions to physical properties are capitalized.

Depreciation of property, plant and equipment is provided using the straight-line method over their estimated useful lives at the following annual rates:

Buildings	2.5% -5	%
Furniture, fixtures and office equipment	20	%
Leasehold improvement	Shorter of the remaining lease terms or estimated useful lives
Machinery and equipment	10	%
Motor vehicles	20	%

Upon sale or disposal, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount less proceeds from disposal is charged or credited to income.

Construction in progress represents capital expenditures for direct costs of construction or acquisition and design fees incurred, and the interest expenses directly related to the construction. Capitalization of these costs ceases and the construction in progress is transferred to the appropriate category of property, plant and equipment when substantially all the activities necessary to prepare the assets for their intended use are completed. Construction in progress is not depreciated.

Land use rights

Land use rights represent payments for the rights to use certain parcels of land for a certain period of time in the PRC. Land use rights are carried at cost and charged to expense on a straight-line basis over the period the rights are granted.

2. Summary of significant accounting policies (continued)

Other assets

Other assets represent a royalty-bearing, non-exclusive license to use certain patents owned by an unrelated party ("License Provider"), to manufacture rechargeable nickel metal hydride batteries for portable consumer applications (“Consumer Batteries”) in the PRC, and a royalty-bearing, non-exclusive worldwide license to use certain patents owned by License Provider to manufacture, sell and distribute Consumer Batteries. The value of the licenses was established based on historic acquisition costs.

An exclusive proprietary technology contributed by the four founding management members of GZ Highpower in exchange for the paid-in capital of GZ Highpower is recorded at the four management members’ historical cost basis of $nil.

Government grants

Government grants are recognized when received and all the conditions for their receipt have been met.

Specifically, government grants whose primary condition is that the Company should purchase, construct or otherwise acquire non-current assets is recognized on the consolidated balance sheet as deferred income and subsequently deducted in calculating the carrying amount of the related asset after the purchase, construction or acquisition completed. As of March 31, 2016 and December 31, 2015, the Company recorded deferred income of $861,369 and $879,944, respectively, for the government grants to purchase non-current assets.

Government grants for the purpose of giving immediate financial support to the Company by local government are recognized as other income when received. In the three months ended March 31, 2016 and 2015, $6,669 and $109,295 of government grants were recognized as other income, respectively.

Revenue recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, the sales price is fixed or determinable, delivery of the product has occurred, title and risk of loss have transferred to the customers and collectability of the receivable is reasonably assured. The majority of domestic sales contracts transfer title and risk of loss to customers upon receipt. The majority of oversea sales contracts transfer title and risk of loss to customers when goods were delivered to the carriers. Revenue is presented net of any sales tax and value added tax.

The Company does not have arrangements for returns from customers and does not have any future obligations directly or indirectly related to product resale by customers. The Company has no sales incentive programs.

Cost of sales

Cost of revenues consists primarily of material costs, employee compensation, depreciation and related expenses, which are directly attributable to the production of products. Write-down of inventories to lower of cost or market is also recorded in cost of revenues.

2. Summary of significant accounting policies (continued)

Research and development

Research and development expenses include expenses directly attributable to the conduct of research and development programs, including the expenses of salaries, employee benefits, materials, supplies, and maintenance of research equipment. All expenses associated with research and development are expensed as incurred.

Advertising

Advertising, which generally represents the cost of promotions to create or stimulate a positive image of the Company or a desire to buy the Company’s products and services, is expensed as incurred. No significant advertising expense was recorded for the three months ended March 31, 2016 and 2015.

Share-based compensation

The Company recognizes compensation expense associated with the issuance of equity instruments to employees for their services. The fair value of the equity instruments is estimated on the date of grant and is expensed in the financial statements over the vesting period. The input assumptions used in determining fair value are the expected life, expected volatility, risk-free rate and the dividend yield.

Share-based compensation associated with the issuance of equity instruments to non-employees is measured at the fair value of the equity instrument issued or committed to be issued, as this is more reliable than the fair value of the services received. The fair value is measured at the earlier of date that the commitment for performance by the counterparty has been reached or the counterparty's performance is complete.

Income taxes

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each period end based on enacted tax laws and statutory tax rates, applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

Uncertain tax positions

The Company accounts for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that the Company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized and recorded as necessary in the provision for income taxes. There were no uncertain tax positions as of March 31, 2016 and December 31, 2015.

Comprehensive loss

Recognized revenue, expenses, gains and losses are included in net income or loss. Although certain changes in assets and liabilities are reported as separate components of the equity section of the consolidated balance sheet, such items, along with net income or loss, are components of comprehensive income or loss. The components of other comprehensive income or loss are consisted solely of foreign currency translation adjustments, net of the income tax effect.

Foreign currency translation and transactions

Highpower’s functional currency is the United States dollar ("US$"). HKHTC's functional currency is the Hong Kong dollar ("HK$"). The functional currency of the Company’s subsidiaries in the PRC is the Renminbi ("RMB").

Most of the Company’s oversea sales are priced and settled with US$. At the date a foreign currency transaction is recognized, each asset, liability, revenue, expense, gain, or loss arising from the transaction is measured initially in the functional currency of the recording entity by use of the exchange rate in effect at that date. The increase or decrease in expected functional currency cash flows upon settlement of a transaction resulting from a change in exchange rates between the functional currency and the currency in which the transaction is denominated is recognized as foreign currency transaction gain or loss that is included in determining net income for the period in which the exchange rate changes. At each balance sheet date, recorded balances that are denominated in a foreign currency are adjusted to reflect the current exchange rate.

The Company’s reporting currency is US$. Assets and liabilities of HKHTC and the PRC subsidiaries are translated at the current exchange rate at the balance sheet dates, revenues and expenses are translated at the average exchange rates during the reporting periods, and equity accounts are translated at historical rates. Translation adjustments are reported in other comprehensive income.

Segment Reporting

The Company uses the “management approach” in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company's chief operating decision maker for making operating decisions and assessing performance as the source for determining the Company's reportable segments. The Company’s reportable segments are based on products, geography, legal structure, management structure, or any other manner in which management disaggregates a company. Therefore the Company categorizes its business into three reportable segments, namely (i) Lithium Batteries; (ii) Ni-MH Batteries; and (iii) New Material.

Fair value of financial instruments

The carrying values of the Company’s financial instruments, including cash, restricted cash, trade and other receivables, deposits, trade and other payables and bank borrowings, approximate their fair values due to the short-term maturity of such instruments.

The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

The Company establishes a fair value hierarchy that requires maximizing the use of observable inputs and minimizing the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

The Company measures fair value using three levels of inputs that may be used to measure fair value:

-Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

-Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

-Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

Warrant Liabilities

For warrants that are not indexed to the Company’s stock, the Company records the fair value of the issued warrants as a liability at each balance sheet date and records changes in the estimated fair value as a non-cash gain or loss in the consolidated statement of operations and comprehensive income. The fair values of these warrants have been determined using the Black-Scholes pricing model. The Black-Scholes pricing model provides for assumptions regarding volatility, call and put features and risk-free interest rates within the total period to maturity. These values are subject to a significant degree of judgment on the part of the Company.

Loss per share

Basic loss per share is computed by dividing loss attributable to holders of common shares by the weighted average number of common shares outstanding during the year. Diluted earnings per share (“EPS”) reflect the potential dilution that could occur if securities or other contracts to issue common shares were exercised or converted into common shares. Potential dilutive securities are excluded from the calculation of diluted EPS in loss periods as their effect would be anti-dilutive.

Recently issued accounting pronouncements

In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, or ASU 2014-09. This new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to correlate with the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year, while allowing a company to adopt the new revenue standard early but not before the original effective date. This guidance will be effective as to us on January 1, 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. In April 2016, the FASB issued Accounting Standards Update 2016-10, Revenue from Contracts with Customers, or ASU 2016-10. These new standards will identify performance obligations. The Company is currently evaluating the impact of adopting ASU 2014-09 on our consolidated financial statements.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740). To simplify the presentation of deferred income taxes, the amendments in this Update require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in this Update apply to all entities that present a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this Update. For public business entities, the amendments in this Update are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. Under this ASU, inventory will be measured at the “lower of cost and net realizable value” and options that currently exist for “market value” will be eliminated. The ASU defines net realizable value as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” No other changes were made to the current guidance on inventory measurement. ASU 2015-11 is effective for interim and annual periods beginning after December 15, 2016. Early application is permitted and should be applied prospectively. The Company plans to early adopt this standard beginning with the 2016 fiscal year, but does not expect the adoption of this standard to have a material impact on the Company's consolidated financial position, results of operations, or related disclosures.

2. Summary of significant accounting policies (continued)

On February 25, 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842). It requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (i.e., January 1, 2019, for a calendar year entity). Early application is permitted for all public business entities and all nonpublic business entities upon issuance. The Company is currently evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements.

In March 2016, the FASB issued Accounting Standards Update (ASU) 2016-09, Compensation—Stock Compensation (Topic 718). Under this update, share-based payment transactions simplified several aspects of the accounting, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas for simplification apply only to nonpublic entities. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. The Company is currently evaluating the impact of adopting ASU 2016-09 on our consolidated financial statements.

We do not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the consolidated financial position, statements of operations and cash flows.

12. Taxation

The Company and its subsidiaries file tax returns separately.

1) VAT

Pursuant to the Provisional Regulation of the PRC on VAT and the related implementing rules, all entities and individuals ("taxpayers") that are engaged in the sale of products in the PRC are generally required to pay VAT at a rate of 17% of the gross sales proceeds received, less any deductible VAT already paid or borne by the taxpayers. Further, when exporting goods, the exporter is entitled to a portion of or all the refund of VAT that it has already paid or incurred. The Company’s PRC subsidiaries are subject to VAT at 17% of their revenues.

2) Income tax

United States

Highpower was incorporated in Delaware and is subject to U.S. federal income tax with a system of graduated tax rates ranging from 15% to 35%. As Highpower does not conduct any business in the U.S., it is not subject to U.S. federal income tax or Delaware state corporate income tax. No deferred U.S. taxes are recorded since all accumulated profits in the PRC will be permanently reinvested in the PRC.

Hong Kong

HKHTC, which is incorporated in Hong Kong, is subject to a corporate income tax rate of 16.5%.

PRC

In accordance with the relevant tax laws and regulations of the PRC, a company registered in the PRC is subject to income taxes within the PRC at the applicable tax rate on taxable income.

In China, the companies granted with National High-tech Enterprise (“NHTE”) status enjoy 15% income tax rate. This status needs to be renewed every three years. As of March 31, 2016, SZ Higpower, SZ Springpower, GZ Highpower, ICON and HZ HTC received NHTE status. Ifthese subsidiaries fail to renew NHTE status, they will be subject to income tax at a rate of 25% after the expiration of NHTE status.

All the PRC subsidiaries received NHTE status and enjoy 15% income tax rate for calendar year 2016 and 2015.

17. Share-based Compensation

The 2008 Omnibus Incentive Plan

The 2008 Omnibus Incentive Plan (the "2008 Plan") was approved by the Company’s Board of Directors on October 29, 2008 to be effective at such date, subject to approval of the Company’s stockholders, which occurred on December 11, 2008. The 2008 Plan has a ten year term. The 2008 Plan reserves two million shares of common stock for issuance, subject to adjustment in the event of a recapitalization in accordance with the terms of the 2008 Plan.

The 2008 Plan authorizes the issuance of awards including stock options, restricted stock units (RSUs), restricted stock, unrestricted stock, stock appreciation rights (SARs) and other equity and/or cash performance incentive awards to employees, directors, and consultants of the Company. Subject to certain restrictions, the Compensation Committee of the Board of Directors has broad discretion to establish the terms and conditions for awards under the 2008 Plan, including the number of shares, vesting conditions and the required service or performance criteria. Options and SARs may have a contractual term of up to ten years and generally vest over three to five years with an exercise price equal to the fair market value on the date of grant. Incentive stock options (ISOs) granted must have an exercise price equal to or greater than the fair market value of the Company’s common stock on the date of grant. Repricing of stock options and SARs is permitted without stockholder approval. If a particular award agreement so provides, certain change in control transactions may cause such awards granted under the 2008 Plan to vest at an accelerated rate, unless the awards are continued or substituted for in connection with the transaction. As of March 31, 2016, 393,141 shares of common stock remained available for issuance pursuant to awards granted under the 2008 Plan.

The aggregate intrinsic value of options vested and expected to vest as of March 31, 2016 and December 31, 2015 was approximately $1,000 and $178,000, respectively. Intrinsic value is calculated as the amount by which the current market value of a share of common stock exceeds the exercise price multiplied by the number of option shares.

During the three months ended March 31, 2016, the Company granted options to purchase 190,000 shares to two employees at a weighted average exercise price of $2.66 per share. No employees exercised their options and no options were forfeited or canceled.

During the three months ended March 31, 2015, the Company did not grant any new options to employees. Three employees exercised their options to purchase 3,551 shares of the Company’s common stock. No Options were forfeited or canceled.

The estimated fair value of share-based compensation to employees is recognized on a ratable basis over the requisite service period, which is generally the vesting period of the award.

18. Loss per share

Basic loss per common share is computed by dividing loss available to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per common share is computed by dividing income available to common stockholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock outstanding that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options and restricted shares. The dilutive effect of potential dilutive securities is reflected in diluted earnings per common share by application of the treasury stock method. Under the treasury stock method, an increase in the fair market value of the Company’s common stock can result in a greater dilutive effect from potentially dilutive securities. The Company excludes potential common stock in the diluted EPS computation in periods of losses from continuing operations, as their effect would be anti-dilutive.

The following table sets forth the computation of basic and diluted earnings per common share for the three months ended March 31, 2016 and 2015.

There were 1,716,927 and 1,406,736 options and warrants outstanding as of March 31, 2016 and 2015, respectively, which were not included in the computation of diluted EPS for the periods ended March 31, 2016 and 2015 because of the net loss sustained for the three months ended March 31, 2016 and 2015.

19. Securities Offering Transaction

In April 2014, the Company and certain institutional investors entered into a securities purchase agreement, pursuant to which the Company sold 1,000,000 shares of common stock and warrants exercisable for 500,000 shares of common stock in a registered direct offering at a price of $5.05 per fixed combination for aggregate proceeds of $5.05 million. The shares and warrants were sold in multiples of a fixed combination consisting of (i) one share of common stock and (ii) one immediately exercisable warrant to purchase 0.50 shares of common stock. The net proceeds from the offering were $4,633,164, after deducting fees due the placement agent and offering expenses.

The warrants have an initial exercise price of $6.33 per share and are exercisable until April 17, 2017. The exercise price of the warrants, and in some cases the number of shares issuable upon exercise of the warrants, will be subject to appropriate adjustment in relation to certain events. In addition, if the Company issues shares in the future at a price below $6.33 per share, the exercise price of the warrants will be reduced to such lower price. No adjustment will be made to the number of shares purchasable in such event.

The warrants were classified as a liability. The aggregate fair value of the warrant liability at issuance dates was $1,173,952. The residual balance of $3,459,212 was allocated to common shares issued.

The fair values of the warrants as of April 17, 2014 were calculated using the Black-Scholes pricing model with the following assumptions:

	April 17,2014
Expected volatility		85.76	%
Risk-free interest rate		0.9	%
Expected term (in years)		3.0
Dividend rate		-
Fair value	$	2.3

The fair value of the warrant liability is re-measured at each reporting period and recorded as a gain or loss on fair value of warrant liability. As of March 31, 2016 and December 31, 2015 the fair value of warrant liability was $21,080 and $140,549, respectively. For the three months ended March 31, 2016 and 2015, the Company recognized a gain of $119,469 and $346,299, respectively, on the change in the fair value of the warrant liability.

The fair values of the warrants as of March 31, 2016 and December 31, 2015 were calculated using the Black-Scholes pricing model with the following assumptions:

	March 31, 2016			December 31,2015
Expected volatility		69.45	%		79.85	%
Risk-free interest rate		0.6	%		0.56	%
Expected term (in years)		1.05			1.30
Dividend rate		-			-
Fair value	$	0.04		$	0.81

In conjunction with the securities offering transaction, the Company issued three year warrants to investment bankers to purchase 40,000 shares of the Company’s common stock at $6.33 per share. The aggregate fair value of the warrants was $94,982, which was recognized as a share-based compensation and resulted in an increase of additional paid-in capital. As such compensation was offering cost, it resulted in a reduction in additional paid-in capital.

20. Defined contribution plan

Full-time employees of the Company in the PRC participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, medical care, employee housing fund and other welfare benefits are provided to employees. Chinese labor regulations require that the PRC operating subsidiaries of the Company make contributions to the government for these benefits based on certain percentages of the employees’ salaries. Except for pension benefits, medical care, employee housing fund and other welfare benefits mentioned above, the Company has no legal obligation for the benefits beyond the contributions made.

The total amounts for such employee benefits, which were expensed as incurred, were $335,558 and $412,688 for the three months ended March 31, 2016 and 2015, respectively.

21. Non-controlling interest

As of March 31, 2016 and December 31, 2015, non-controlling interest related to the 30% minority interest in GZ Highpower in the consolidated balance sheet was $724,661 and $853,483, respectively.

Contingencies

On January 14, 2016, FirsTrust China, Ltd filed an amended complaint in the Delaware Chancery Court (amending its initial complaint filed February 25, 2015) naming Highpower as the defendant asserting a cause of action for breach of contract and conversion of stock, and seeking damages in the form of issuance of 150,000 shares or the value of such shares, plus interest thereon, attorneys’ fees and costs and expenses. On February 4, 2016, Highpower filed an answer, affirmative defenses and counterclaim against FirsTrust asserting claims for equitable rescission, declaratory relief and breach of contract, and seeking rescission of the contract, return of the 200,000 warrants and 150,000 shares of Highpower stock previously issued to FirsTrust, plus interest, attorneys’ fees and costs and expenses. The Company believes that it has meritorious defenses to this claim and intends to defend the claim vigorously. Highpower has also added as counter-defendants four individuals to whom it issued shares pursuant to FirsTrust’s request. In April 2016, FirsTrust filed a motion for judgment on the pleadings with respect to its complaint and a hearing date is scheduled for July 2016.

Overview

Highpower was incorporated in the state of Delaware on January 3, 2006 and was originally organized as a “blank check” shell company to investigate and acquire a target company or business seeking the perceived advantages of being a publicly held corporation. On November 2, 2007, we closed a share exchange transaction, pursuant to which we (i) became the 100% parent of HKHTC and its wholly-owned subsidiary, SZ Highpower, (ii) assumed the operations of HKHTC and its subsidiary and (iii) changed our name to Hong Kong Highpower Technology, Inc. We subsequently changed our name to Highpower International, Inc. in October 2010.

HKHTC was incorporated in Hong Kong in 2003 under the Companies Ordinance of Hong Kong. HKHTC formed HZ Highpower and SZ Springpower in 2008. HZ Highpower was dissolved in 2015. On October 8, 2013, SZ Springpower further increased its registered capital to $15,000,000. SZ Highpower holds 69.97% of the equity interest of SZ Springpower, and HKHTC holds the remaining 30.03%. In February 2011, HKHTC formed another wholly-owned subsidiary, Icon Energy System Company Limited, a company organized under the laws of the PRC, which commenced operations in July 2011.

On May 15, 2013, GZ Highpower increased its paid-in capital from RMB15,000,000 ($2,381,293) to RMB30,000,000 ($4,807,847). On November 13, 2014, GZ Highpower increased its paid-in capital from RMB30,000,000 ($4,898,119) to RMB40,000,000 ($6,530,825) and the additional capital of RMB10,000,000 was contributed by SZ Highpower. As of March 31, 2016, SZ Highpower holds 70% of the equity interest of GZ Highpower, and four founding management members of GZ Highpower hold the remaining 30%.

On November 27, 2015, the Company’s Board of Directors received a non-binding investment proposal letter from Anshan Co-Operation (Group) Co., Ltd. ("Anshan Co-Operation"), joined with Mr. DANG YU Pan, the Company’s Chairman and CEO, and certain management of Highpower International, and China Innovative Capital Management Ltd. Anshan Co-Operation (Group) Co., Ltd. ("Anshan Co-Operation"), proposing to purchase newly issued shares of Shenzhen Highpower Technology Co., Ltd., Springpower Technology (Shenzhen) Co., Ltd. and Icon Energy System (Shenzhen) Co., Ltd., the three subsidiaries in the PRC wholly-owned by the Company with not less than RMB650 million, or approximately US$101.7 million (based on an exchange rate of $6.39 as of November 26, 2015) based on the valuation of RMB280 million, or approximately US$43.8 million (based on an exchange rate of $6.39 as of November 26, 2015) for the three subsidiaries, in exchange for more than 50% of the equity of each of the three subsidiaries and become the controlling shareholder of each of the subsidiaries after the subscription. The Company's Board of Directors has formed a special committee consisting of the following independent directors to consider the proposal: Ping Li, who will serve as chairman, Xinhai Li and T. Joseph Fisher, III. The special committee has retained independent legal and financial advisors to assist it in the process.

Through SZ Highpower, we manufacture Nickel Metal Hydride (“Ni-MH”) batteries for both consumer and industrial applications. We have developed significant expertise in Ni-MH battery technology and large-scale manufacturing that enables us to improve the quality of our battery products, reduce costs, and keep pace with evolving industry standards. In 2008, we commenced manufacturing two lines of Lithium-Ion (“Li-ion”) and Lithium polymer rechargeable batteries through SZ Springpower for higher-end, high-performance applications, such as laptops, digital cameras and wireless communication products. Our automated machinery allows us to process key aspects of the manufacturing process to ensure high uniformity and precision, while leaving the non-key aspects of the manufacturing process to manual labor.

We employ a broad network of sales staff in China and Hong Kong, which target key customers by arranging in-person sales presentations and providing post-sale services. The sales staff works with our customers to better address customers’ needs.

The Securities and Exchange Commission (“SEC”) defines critical accounting policies as those that are, in management's view, most important to the portrayal of our financial condition and results of operations and those that require significant judgments and estimates.

The preparation of these consolidated financial statements requires our management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as the disclosure of contingent assets and liabilities at the date of our financial statements. We base our estimates on historical experience, actuarial valuations and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Some of those judgments can be subjective and complex and, consequently, actual results may differ from these estimates under different assumptions or conditions. While for any given estimate or assumption made by our management there may be other estimates or assumptions that are reasonable, we believe that, given the current facts and circumstances, it is unlikely that applying any such other reasonable estimate or assumption would materially impact the financial statements. The accounting principles we utilized in preparing our consolidated financial statements conform in all material respects to U.S. generally accepted accounting principles (U.S. GAAP).

36

Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant items subject to such estimates and assumptions include, but are not limited to, revenues; the allowance for doubtful receivables; recoverability of the carrying amount of inventory; fair values of financial instruments; and the assessment of deferred tax assets or liabilities. These estimates are often based on complex judgments and assumptions that management believes to be reasonable but are inherently uncertain and unpredictable. Actual results could differ significantly from these estimates.

Accounts Receivable. Accounts receivable are stated at original amount less allowance made for doubtful receivables, if any, based on a review of all outstanding amounts at the period end. An allowance is also made when there is objective evidence that the Company will not be able to collect all amounts due according to the original terms of receivables. Bad debts are written off against the allowance after all collection efforts have ceased. The Company extends unsecured credit to customers in the normal course of business and believes all accounts receivable in excess of the allowances for doubtful receivables to be fully collectible. The Company does not accrue interest on trade accounts receivable.

Revenue Recognition. The Company recognizes revenue when persuasive evidence of an arrangement exists, the sales price is fixed or determinable, delivery of the product has occurred, title and risk of loss have transferred to the customers and collectability of the receivable is reasonably assured. The majority of domestic sales contracts transfer title and risk of loss to customers upon receipt. The majority of oversea sales contracts transfer title and risk of loss to customers when goods were delivered to the carriers. Revenue is presented net of any sales tax and value added tax.

The Company does not have arrangements for returns from customers and does not have any future obligations directly or indirectly related to product resale by the customer. We have no incentive programs.

Inventories. Inventories are stated at the lower of cost or market value. Costs are determined on a weighted-average method. Inventory includes raw materials, packing materials, work-in-process, consumables and finished goods. The variable production overhead is allocated to each unit of production on the basis of the actual use of the production facilities. The allocation of fixed production overhead to the costs of conversion is based on the normal capacity of the production facilities.

Income Taxes. The Company recognizes deferred assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred income taxes are recognized for the consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each period end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

Foreign Currency Translation and Transactions. Highpower International’s functional currency is the United States dollar (“US$”). HKHTC’s functional currency is the Hong Kong dollar (“HK$”). The functional currency of the Company’s subsidiaries in the PRC is the Renminbi (“RMB”).

At the date a foreign currency transaction is recognized, each asset, liability, revenue, expense, gain, or loss arising from the transaction is measured initially in the functional currency of the recording entity by use of the exchange rate in effect at that date. The increase or decrease in expected functional currency cash flows upon settlement of a transaction resulting from a change in exchange rates between the functional currency and the currency in which the transaction is denominated is recognized as foreign currency transaction gain or loss that is included in determining net income for the period in which the exchange rate changes. At each balance sheet date, recorded balances that are denominated in a foreign currency are adjusted to reflect the current exchange rate.

The Company’s reporting currency is the US$. Assets and liabilities of HKHTC and the PRC subsidiaries are translated at the current exchange rate at the balance sheet dates, revenues and expenses are translated at the average exchange rates during the reporting periods, and equity accounts are translated at historical rates. Translation adjustments are reported in other comprehensive income.

Three months ended March 31, 2016 and 2015

Net sales

We generate revenues from the sale of our Ni-MH batteries, Lithium batteries and new materials for three months ended March 31, 2016. Revenues by segment were as follows:

	Three months ended March 31 ,
	2016		2015
	(Unaudited)		(Unaudited)
	$		$
Net sales
Lithium Batteries		15,314,945		16,820,628
Ni-MH Batteries		12,856,325		14,759,470
New Materials		925,785		557,550
Total		29,097,055		32,137,648

38

Net sales for the three months ended March 31, 2016 were $29.1 million compared to $32.1 million for the three months ended March 31, 2015, a decrease of $3.0 million, or 9.5%.The decrease was due to a $1.5 million decrease in net sales of our lithium batteries (resulting from a 6.1% decrease in the volume, measured in ampere hour, of batteries sold and a 3.1% decrease in the average selling price of such batteries), a $1.9 million decrease in net sales of our Ni-MH batteries (resulting from a 12.9% decrease in the average selling price of such batteries) and a $0.4 million increase in revenue from our new material business. The decrease of lithium batteries sales was mainly due to the decline of sales of iPhone backup power products.

Cost of sales

Cost of sales mainly consists of nickel, cobalt, lithium derived materials, labor, and overhead. Costs of sales were $23.2 million for the three months ended March 31, 2016, as compared to $26.6 million for the comparable period in 2015. As a percentage of net sales, cost of sales decreased to 79.8% for the three months ended March 31, 2016 compared to 82.7% for the comparable period in 2015, which was mainly due to the decrease of price of raw material as well as labor cost.

Gross profit

Gross profit for the three months ended March 31, 2016 was $5.9 million, or 20.2% of net sales, compared to $5.6 million, or 17.3% of net sales for the comparable period in 2015. Management considers gross profit margin a key performance indicator in managing our business. Gross profit margins are usually a factor of cost of sales, product mix and demand for product. This increase was attributable to improved production efficiency.

To cope with pressure on our gross margins we control production costs by preparing budgets for each department and comparing actual costs with our budgeted figures monthly and quarterly. Additionally, we have reorganized the Company’s production structure and have focused more attention on employee training to enhance efficiency. We also intend to expand our market share by investing in greater promotion of our products in regions such as the U.S., Russia, Europe and India, and by expanding our sales team with more experienced sales personnel. We have also begun production capacity expansion for our lithium batteries business to take advantage of the strong demand for such products globally.

Research and development

Research and development expenses were $1.6 million, or 5.6% of net sales, for the three months ended March 31, 2016, as compared to $1.7 million, or 5.2% of net sales for the comparable period in 2015.

Selling and distribution expenses

Selling and distribution expenses were $1.5 million, or 5.3% of net sales, for the three months ended March 31, 2016 compared to $1.8 million, or 5.6% of net sales, for the comparable period in 2015, a decrease of 14.7%. Selling and distribution expenses decreased due to a decrease in net sales.

General and administrative expenses

General and administrative expenses were $3.1 million, or 10.5% of net sales, for the three months ended March 31, 2016, compared to $3.0 million, or 9.4% of net sales, for the comparable period in 2015.

Foreign currency transaction (loss) gain

We experienced a loss of $90,436 for the three months ended March 31, 2016 and a gain of $370,311 for the three months ended March 31, 2015 on the exchange rate difference between the U.S. Dollar and the RMB. The gain (loss) in exchange rate difference was due to the influence of the RMB relative to the U.S. Dollar over the respective periods.

Interest expenses

Interest expenses were $274,992 for the three months ended March 31, 2016, as compared to $268,642 for the comparable period in 2015.

39

Other income

Other income, which consists of bank interest income, government grants and sundry income, was approximately $155,928 for the three months ended March 31, 2016, as compared to approximately $230,092 for the comparable period in 2015, a decrease of $74,164.

Change in fair value change of warrant liabilities

Change in fair value change of warrant liabilities was $119,469 for the three months ended March 31, 2016, as compared to a gain of $346,299, for the comparable period in 2015. It represented the fair value change of 500,000 shares of warrants issued on April 17, 2014.

Income tax (expenses) benefit

During the three months ended March 31, 2016, we recorded provision for income tax expense of $35,504 as compared to income tax benefit of $95,256 for the comparable period in 2015.

Net loss

Net loss attributable to the Company (excluding net loss attributable to non-controlling interest) for the three months ended March 31, 2016 was $342,608, compared to net loss attributable to the Company (excluding net loss attributable to non-controlling interest) of $123,358 for the comparable period in 2015.

40

Foreign Currency and Exchange Risk

Though the reporting currency is the US$, the Company maintains its financial records in the functional currency of Renminbi (“RMB”). Substantially all of our operations are conducted in the PRC and we pay the majority of our expenses in RMB. Approximately 60% of our sales are made in U.S. Dollars. During the three months ended March 31, 2016, the exchange rate of the RMB to the U.S. Dollar devaluated 0.7% from the level at the end of December 31, 2015. Future appreciation of the RMB against the U.S. Dollar would increase our costs when translated into U.S. Dollars and could adversely affect our margins unless we make sufficient offsetting sales. Conversion of RMB into foreign currencies is regulated by the People’s Bank of China through a unified floating exchange rate system. Although the PRC government has stated its intention to support the value of the RMB, there can be no assurance that such exchange rate will not continue to appreciate significantly against the U.S. Dollar. Exchange rate fluctuations may also affect the value, in U.S. Dollar terms, of our net assets. In addition, the RMB is not freely convertible into foreign currency and all foreign exchange transactions must take place through authorized institutions. Due to the volatility of the US Dollar to our functional currency the Company put into place a hedging program to attempt to protect it from significant changes to the US Dollar which affects the value of its US dollar receivables and sales.

Liquidity and Capital Resources

We had cash and cash equivalents of approximately $6.7 million as of March 31, 2016, as compared to $5.8 million as of December 31, 2015. Our funds are kept in financial institutions located in the PRC, which do not provide insurance for amounts on deposit. Moreover, we are subject to the regulations of the PRC which restrict the transfer of cash from the PRC, except under certain specific circumstances. Accordingly, such funds may not be readily available to us to satisfy obligations incurred outside the PRC.

To provide liquidity and flexibility in funding our operations, we borrowed funds under bank facilities and other external sources of financing. As of March 31, 2016, we had lines of credit with 8 financial institutions aggregating $76 million. The maturity of these facilities is generally within one year. The facilities are subject to regular review and approval. Certain of these banking facilities are guaranteed by our Chief Executive Officer, Mr. Dang Yu Pan, pledged by land use right and buildings, and contain customary affirmative and negative covenants for secured credit facilities of this type. Interest rates are generally based on the banks’ reference lending rates. No significant commitment fees are required to be paid for the banking facilities. As of March 31, 2016, we had utilized approximately $39 million under such general credit facilities and had available unused credit facilities of $37 million.

For the three months ended March 31, 2016, net cash provided by operating activities was approximately $4.0 million, as compared to $6.5 million used in operating activities for the comparable period in 2015. The net cash increase of $10.5 million used in operating activities is primarily attributable to, among other items, an increase of $4.7 million in cash inflow from accounts receivable, a decrease of $2.8 million in outflow from accounts payable.

Net cash used in investing activities was $1.1 million for the three months ended March 31, 2016 compared to $1.7 million for the comparable period in 2015. The net decrease of $0.6 million of cash used in investing activities was primarily attributable to a decrease in cash outflow from acquisition of plant and equipment for increase Auto-equipment.

Net cash used in financing activities was $2.0 million during the three months ended March 31, 2016, as compared to $3.6 million provided by financing activities for the comparable period in 2015. The net decrease of $5.6 million in net cash used in financing activities was primarily attributable to a decrease of $7.4 million in proceeds from notes payable and an increase of $1.5 million in proceeds from short-term bank loan.

For each of the three months ended March 31, 2016 and 2015, our inventory turnover was 4.8 times. The average days outstanding of our accounts receivable at March 31, 2016 was 105 days, as compared to 88 days at March 31, 2015. Inventory turnover and average days outstanding are key operating measures that management relies on to monitor our business.

In the next 12 months, we expect to expand our research, development and manufacturing of lithium-based batteries and anticipate additional capital expenditures.

41

We are required to contribute a portion of our employees’ total salaries to the Chinese government’s social insurance funds, including medical insurance, unemployment insurance and job injuries insurance, and a housing assistance fund, in accordance with relevant regulations. Total contributions to the funds were approximately $335,558 and $412,688 for the three months ended March 31, 2016 and 2015, respectively. We expect the amount of our contribution to the government’s social insurance funds to increase in the future as we expand our workforce and operations.

Based upon our present plans, we believe that cash on hand, cash flow from operations and funds available under our bank facilities will be sufficient to meet our capital needs for the next 12 months. However, our ability to maintain sufficient liquidity depends partially on our ability to achieve anticipated levels of revenue, while continuing to control costs. If we did not have sufficient available cash, we would have to seek additional debt or equity financing through other external sources, which may not be available on acceptable terms, or at all. Failure to maintain financing arrangements on acceptable terms would have a material adverse effect on our business, results of operations and financial condition.

The use of working capital is primarily for the maintenance of our accounts receivable and inventory. We provide our major customers with payment terms ranging from 30 to 90 days. Additionally, our production lead time is approximately 30 to 40 days, from the inspection of incoming materials, to production, testing and packaging. We need to keep a large supply of raw materials, work-in-process and finished goods inventory on hand to ensure timely delivery of our products to customers. We use two methods to support our working capital needs: (i) paying our suppliers under payment terms ranging from 60 to 120 days; and (ii) using short-term bank loans. Upon receiving payment for our accounts receivable, we pay our short-term loans. Our working capital management practices are designed to ensure that we maintain sufficient working capital.

Recent Accounting Pronouncements

As of May 16, 2016, the Financial Accounting Standards Board (“FASB”) has issued ASU No. 2016-1 Financial Instruments through ASU No. 2016-11 Revenue Recognition and Derivatives and Hedging.

In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, or ASU 2014-09. This new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to correlate with the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year, while allowing a company to adopt the new revenue standard early but not before the original effective date. This guidance will be effective as to us on January 1, 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. In March and April 2016, the FASB issued Accounting Standards Update 2016-08 and 2016-10, Revenue from Contracts with Customers, or ASU 2016-08 and ASU 2016-10. These new standards will amend the reporting revenue gross versus net and identify performance obligations and licensing. The Company is currently evaluating the impact of adopting ASU 2014-09 on our consolidated financial statements.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740). To simplify the presentation of deferred income taxes, the amendments in this Update require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in this Update apply to all entities that present a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this Update. For public business entities, the amendments in this Update are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.

42

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. Under this ASU, inventory will be measured at the “lower of cost and net realizable value” and options that currently exist for “market value” will be eliminated. The ASU defines net realizable value as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” No other changes were made to the current guidance on inventory measurement. ASU 2015-11 is effective for interim and annual periods beginning after December 15, 2016. Early application is permitted and should be applied prospectively. The Company plans to early adopt this standard beginning with the 2016 fiscal year, but does not expect the adoption of this standard to have a material impact on the Company's consolidated financial position, results of operations, or related disclosures.

On February 25, 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842). It requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (i.e., January 1, 2019, for a calendar year entity). Early application is permitted for all public business entities and all nonpublic business entities upon issuance. The Company is currently evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements.

In March 2016, the FASB issued Accounting Standards Update (ASU) 2016-09, Compensation—Stock Compensation (Topic 718). Under this update, share-based payment transactions simplified several aspects of the accounting, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas for simplification apply only to nonpublic entities. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. The Company is currently evaluating the impact of adopting ASU 2016-09 on our consolidated financial statements.

We do not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the consolidated financial position, statements of operations and cash flows.

Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

1. Organization and basis of presentation

The consolidated financial statements include the financial statements of Highpower International, Inc. ("Highpower") and its subsidiaries, Hong Kong Highpower Technology Company Limited ("HKHTC"), Shenzhen Highpower Technology Company Limited ("SZ Highpower"), Springpower Technology (Shenzhen) Company Limited ("SZ Springpower"), Ganzhou Highpower Technology Company Limited ("GZ Highpower"), Icon Energy System Company Limited ("ICON") and Huizhou Highpower Technology Co., Ltd (HZ HTC). Highpower and its subsidiaries are collectively referred to as the "Company".

Highpower was incorporated in the State of Delaware on January 3, 2006. HKHTC was incorporated in Hong Kong on July 4, 2003. All other subsidiaries are incorporated in the People’s Republic of China (“PRC”).

On May 15, 2013, GZ Highpower increased its paid-in capital from RMB15,000,000 ($2,381,293) to RMB30,000,000 ($4,807,847). On November 13, 2014, GZ Highpower increased its paid-in capital from RMB30,000,000 ($4,898,119) to RMB40,000,000 ($6,530,825) and the additional capital of RMB10,000,000 was contributed by SZ Highpower. As of March 31, 2016, SZ Highpower holds 70% of the equity interest of GZ Highpower, and four founding management members of GZ Highpower hold the remaining 30%.

In April 2014, the Company and certain institutional investors entered into a securities purchase agreement, pursuant to which the Company sold 1,000,000 shares of common stock and warrants exercisable for 500,000 shares of common stock in a registered direct offering at a price of $5.05 per fixed combination for aggregate proceeds of $5.05 million. The shares and warrants were sold in multiples of a fixed combination consisting of (i) one share of common stock and (ii) one immediately exercisable warrant to purchase 0.50 shares of common stock. The net proceeds from the offering were $4,633,164, after deducting fees due the placement agent and offering expenses.

Highpower Energy Technology (Huizhou) Company Limited (“HZ Highpower”) which was formed by HKHTC in 2008, was dissolved in September 2015. The subsidiary did not commence operation since establishment. Therefore, the Company did not consider it as a strategic shift.

Significant Accounting Policies [Text Block]

2. Summary of significant accounting policies

Basis of presentation

The accompanying consolidated balance sheet as of December 31, 2015, which has been derived from audited financial statements, and the unaudited interim consolidated financial statements as of March 31, 2016 and for the three ended March 31, 2016 and 2015 have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and disclosures, which are normally included in financial statements prepared in accordance with United States generally accepted accounting principles (U.S. GAAP), have been condensed or omitted pursuant to such rules and regulations. The interim financial information should be read in conjunction with the Financial Statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, previously filed with the SEC on March 29, 2016.

In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present a fair presentation of the Company’s consolidated financial position as of March 31, 2016, its consolidated results of operations and cash flows for the three months ended March 31, 2016 and 2015, as applicable, have been made. The interim results of operations are not necessarily indicative of the operating results for the full fiscal year or any future periods.

Principles of consolidation

 

The consolidated financial statements include the accounts of Highpower and its subsidiaries. All significant inter-company accounts and transactions have been eliminated in consolidation. Non-controlling interests represent the equity interest in the GZ Highpower that is not attributable to the Company.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant items subject to such estimates and assumptions include revenues; the allowance for doubtful receivables; recoverability of the carrying amount of inventory; fair values of financial instruments; and the assessment of deferred tax assets or liabilities. These estimates are often based on complex judgments and assumptions that management believes to be reasonable but are inherently uncertain and unpredictable. Actual results could differ significantly from these estimates.

Concentrations of credit risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of accounts receivable. The Company extends credit based on an evaluation of the customer’s financial condition, generally without requiring collateral or other security. In order to minimize the credit risk, the management of the Company has delegated a team responsible for determining credit limits, credit approvals and other monitoring procedures to ensure that follow-up action is taken to recover overdue debts. Further, the Company reviews the recoverable amount of each individual trade debt at each balance sheet date to ensure that adequate impairment losses are made for irrecoverable amounts. In this regard, the management of the Company considers that the Company’s credit risk is significantly reduced.

No customer accounted for 10% or more of total sales during the three months ended March 31, 2016 and 2015.

There was one major supplier that accounted for 14.4% of the total purchase amount during the three months ended March 31, 2016. And no supplier accounted for 10% or more of the total purchase amount during the three months ended March 31, 2015.

There was one major customer that accounted for 11.5% and 11.3% of the accounts receivable as of March 31, 2016 and December 31, 2015, respectively.

Cash

Cash include all cash and deposits in banks with initial maturities of three months or less.

Restricted cash

Restricted cash include time deposits and cash security for bank acceptance bills included in notes payable.

Accounts receivable

Accounts receivable are stated at the original amount less an allowance for doubtful receivables, if any, based on a review of all outstanding amounts at period end. An allowance is also made when there is objective evidence that the Company will not be able to collect all amounts due according to the original terms of the receivables. Bad debts are written off against the allowance after all collection efforts have ceased. The Company extends unsecured credit to customers in the normal course of business and believes all accounts receivable in excess of the allowances for doubtful receivables to be fully collectible. The Company does not accrue interest on trade accounts receivable.

Notes receivable

Notes receivable represent banks’ and commercial acceptances that have been arranged with third-party financial institutions by certain customers to settle their purchases from us. These banks’ acceptances are non-interest bearing and are collectible within one year.

Inventories

Inventories are stated at lower of cost or market. Cost is determined using the weighted average method. Inventory includes raw materials, packing materials, consumables, work in progress and finished goods. The variable production overhead is allocated to each unit of production on the basis of the actual use of the production facilities. The allocation of fixed production overhead to the costs of conversion is based on the normal capacity of the production facilities.

Property, plant and equipment

Property, plant and equipment, net are stated at cost less accumulated depreciation. Cost represents the purchase price of the asset and other costs incurred to bring the asset into its existing use. Maintenance, repairs and betterments, including replacement of minor items, are charged to expense; major additions to physical properties are capitalized.

Depreciation of property, plant and equipment is provided using the straight-line method over their estimated useful lives at the following annual rates:

Buildings	2.5% -5	%
Furniture, fixtures and office equipment	20	%
Leasehold improvement	Shorter of the remaining lease terms or estimated useful lives
Machinery and equipment	10	%
Motor vehicles	20	%

Upon sale or disposal, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount less proceeds from disposal is charged or credited to income.

Construction in progress represents capital expenditures for direct costs of construction or acquisition and design fees incurred, and the interest expenses directly related to the construction. Capitalization of these costs ceases and the construction in progress is transferred to the appropriate category of property, plant and equipment when substantially all the activities necessary to prepare the assets for their intended use are completed. Construction in progress is not depreciated.

Land use rights

Land use rights represent payments for the rights to use certain parcels of land for a certain period of time in the PRC. Land use rights are carried at cost and charged to expense on a straight-line basis over the period the rights are granted.

Other assets

Other assets represent a royalty-bearing, non-exclusive license to use certain patents owned by an unrelated party ("License Provider"), to manufacture rechargeable nickel metal hydride batteries for portable consumer applications (“Consumer Batteries”) in the PRC, and a royalty-bearing, non-exclusive worldwide license to use certain patents owned by License Provider to manufacture, sell and distribute Consumer Batteries. The value of the licenses was established based on historic acquisition costs.

An exclusive proprietary technology contributed by the four founding management members of GZ Highpower in exchange for the paid-in capital of GZ Highpower is recorded at the four management members’ historical cost basis of $nil.

Government grants

Government grants are recognized when received and all the conditions for their receipt have been met.

Specifically, government grants whose primary condition is that the Company should purchase, construct or otherwise acquire non-current assets is recognized on the consolidated balance sheet as deferred income and subsequently deducted in calculating the carrying amount of the related asset after the purchase, construction or acquisition completed. As of March 31, 2016 and December 31, 2015, the Company recorded deferred income of $861,369 and $879,944, respectively, for the government grants to purchase non-current assets.

Government grants for the purpose of giving immediate financial support to the Company by local government are recognized as other income when received. In the three months ended March 31, 2016 and 2015, $6,669 and $109,295 of government grants were recognized as other income, respectively.

Revenue recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, the sales price is fixed or determinable, delivery of the product has occurred, title and risk of loss have transferred to the customers and collectability of the receivable is reasonably assured. The majority of domestic sales contracts transfer title and risk of loss to customers upon receipt. The majority of oversea sales contracts transfer title and risk of loss to customers when goods were delivered to the carriers. Revenue is presented net of any sales tax and value added tax.

The Company does not have arrangements for returns from customers and does not have any future obligations directly or indirectly related to product resale by customers. The Company has no sales incentive programs.

Cost of sales

Cost of revenues consists primarily of material costs, employee compensation, depreciation and related expenses, which are directly attributable to the production of products. Write-down of inventories to lower of cost or market is also recorded in cost of revenues.

Research and development

Research and development expenses include expenses directly attributable to the conduct of research and development programs, including the expenses of salaries, employee benefits, materials, supplies, and maintenance of research equipment. All expenses associated with research and development are expensed as incurred.

Advertising

Advertising, which generally represents the cost of promotions to create or stimulate a positive image of the Company or a desire to buy the Company’s products and services, is expensed as incurred. No significant advertising expense was recorded for the three months ended March 31, 2016 and 2015.

Share-based compensation

The Company recognizes compensation expense associated with the issuance of equity instruments to employees for their services. The fair value of the equity instruments is estimated on the date of grant and is expensed in the financial statements over the vesting period. The input assumptions used in determining fair value are the expected life, expected volatility, risk-free rate and the dividend yield.

Share-based compensation associated with the issuance of equity instruments to non-employees is measured at the fair value of the equity instrument issued or committed to be issued, as this is more reliable than the fair value of the services received. The fair value is measured at the earlier of date that the commitment for performance by the counterparty has been reached or the counterparty's performance is complete.

Income taxes

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each period end based on enacted tax laws and statutory tax rates, applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

Uncertain tax positions

The Company accounts for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that the Company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized and recorded as necessary in the provision for income taxes. There were no uncertain tax positions as of March 31, 2016 and December 31, 2015.

Comprehensive loss

Recognized revenue, expenses, gains and losses are included in net income or loss. Although certain changes in assets and liabilities are reported as separate components of the equity section of the consolidated balance sheet, such items, along with net income or loss, are components of comprehensive income or loss. The components of other comprehensive income or loss are consisted solely of foreign currency translation adjustments, net of the income tax effect.

Foreign currency translation and transactions

Highpower’s functional currency is the United States dollar ("US$"). HKHTC's functional currency is the Hong Kong dollar ("HK$"). The functional currency of the Company’s subsidiaries in the PRC is the Renminbi ("RMB").

Most of the Company’s oversea sales are priced and settled with US$. At the date a foreign currency transaction is recognized, each asset, liability, revenue, expense, gain, or loss arising from the transaction is measured initially in the functional currency of the recording entity by use of the exchange rate in effect at that date. The increase or decrease in expected functional currency cash flows upon settlement of a transaction resulting from a change in exchange rates between the functional currency and the currency in which the transaction is denominated is recognized as foreign currency transaction gain or loss that is included in determining net income for the period in which the exchange rate changes. At each balance sheet date, recorded balances that are denominated in a foreign currency are adjusted to reflect the current exchange rate.

The Company’s reporting currency is US$. Assets and liabilities of HKHTC and the PRC subsidiaries are translated at the current exchange rate at the balance sheet dates, revenues and expenses are translated at the average exchange rates during the reporting periods, and equity accounts are translated at historical rates. Translation adjustments are reported in other comprehensive income.

Segment Reporting

The Company uses the “management approach” in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company's chief operating decision maker for making operating decisions and assessing performance as the source for determining the Company's reportable segments. The Company’s reportable segments are based on products, geography, legal structure, management structure, or any other manner in which management disaggregates a company. Therefore the Company categorizes its business into three reportable segments, namely (i) Lithium Batteries; (ii) Ni-MH Batteries; and (iii) New Material.

Fair value of financial instruments

The carrying values of the Company’s financial instruments, including cash, restricted cash, trade and other receivables, deposits, trade and other payables and bank borrowings, approximate their fair values due to the short-term maturity of such instruments.

The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

The Company establishes a fair value hierarchy that requires maximizing the use of observable inputs and minimizing the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

The Company measures fair value using three levels of inputs that may be used to measure fair value:

-Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

-Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

-Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

Warrant Liabilities

For warrants that are not indexed to the Company’s stock, the Company records the fair value of the issued warrants as a liability at each balance sheet date and records changes in the estimated fair value as a non-cash gain or loss in the consolidated statement of operations and comprehensive income. The fair values of these warrants have been determined using the Black-Scholes pricing model. The Black-Scholes pricing model provides for assumptions regarding volatility, call and put features and risk-free interest rates within the total period to maturity. These values are subject to a significant degree of judgment on the part of the Company.

Loss per share

Basic loss per share is computed by dividing loss attributable to holders of common shares by the weighted average number of common shares outstanding during the year. Diluted earnings per share (“EPS”) reflect the potential dilution that could occur if securities or other contracts to issue common shares were exercised or converted into common shares. Potential dilutive securities are excluded from the calculation of diluted EPS in loss periods as their effect would be anti-dilutive.

Recently issued accounting pronouncements

In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, or ASU 2014-09. This new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to correlate with the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year, while allowing a company to adopt the new revenue standard early but not before the original effective date. This guidance will be effective as to us on January 1, 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. In April 2016, the FASB issued Accounting Standards Update 2016-10, Revenue from Contracts with Customers, or ASU 2016-10. These new standards will identify performance obligations. The Company is currently evaluating the impact of adopting ASU 2014-09 on our consolidated financial statements.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740). To simplify the presentation of deferred income taxes, the amendments in this Update require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in this Update apply to all entities that present a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this Update. For public business entities, the amendments in this Update are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. Under this ASU, inventory will be measured at the “lower of cost and net realizable value” and options that currently exist for “market value” will be eliminated. The ASU defines net realizable value as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” No other changes were made to the current guidance on inventory measurement. ASU 2015-11 is effective for interim and annual periods beginning after December 15, 2016. Early application is permitted and should be applied prospectively. The Company plans to early adopt this standard beginning with the 2016 fiscal year, but does not expect the adoption of this standard to have a material impact on the Company's consolidated financial position, results of operations, or related disclosures.

 

On February 25, 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842). It requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (i.e., January 1, 2019, for a calendar year entity). Early application is permitted for all public business entities and all nonpublic business entities upon issuance. The Company is currently evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements.

In March 2016, the FASB issued Accounting Standards Update (ASU) 2016-09, Compensation—Stock Compensation (Topic 718). Under this update, share-based payment transactions simplified several aspects of the accounting, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas for simplification apply only to nonpublic entities. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. The Company is currently evaluating the impact of adopting ASU 2016-09 on our consolidated financial statements.

We do not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the consolidated financial position, statements of operations and cash flows.

12. Taxation

 

The Company and its subsidiaries file tax returns separately.

1) VAT

Pursuant to the Provisional Regulation of the PRC on VAT and the related implementing rules, all entities and individuals ("taxpayers") that are engaged in the sale of products in the PRC are generally required to pay VAT at a rate of 17% of the gross sales proceeds received, less any deductible VAT already paid or borne by the taxpayers. Further, when exporting goods, the exporter is entitled to a portion of or all the refund of VAT that it has already paid or incurred. The Company’s PRC subsidiaries are subject to VAT at 17% of their revenues.

2) Income tax

United States

Highpower was incorporated in Delaware and is subject to U.S. federal income tax with a system of graduated tax rates ranging from 15% to 35%. As Highpower does not conduct any business in the U.S., it is not subject to U.S. federal income tax or Delaware state corporate income tax. No deferred U.S. taxes are recorded since all accumulated profits in the PRC will be permanently reinvested in the PRC.

Hong Kong

HKHTC, which is incorporated in Hong Kong, is subject to a corporate income tax rate of 16.5%.

PRC

In accordance with the relevant tax laws and regulations of the PRC, a company registered in the PRC is subject to income taxes within the PRC at the applicable tax rate on taxable income.

In China, the companies granted with National High-tech Enterprise (“NHTE”) status enjoy 15% income tax rate. This status needs to be renewed every three years. As of March 31, 2016, SZ Higpower, SZ Springpower, GZ Highpower, ICON and HZ HTC received NHTE status. If these subsidiaries fail to renew NHTE status, they will be subject to income tax at a rate of 25% after the expiration of NHTE status.

All the PRC subsidiaries received NHTE status and enjoy 15% income tax rate for calendar year 2016 and 2015.

The 2008 Omnibus Incentive Plan

The 2008 Omnibus Incentive Plan (the "2008 Plan") was approved by the Company’s Board of Directors on October 29, 2008 to be effective at such date, subject to approval of the Company’s stockholders, which occurred on December 11, 2008. The 2008 Plan has a ten year term. The 2008 Plan reserves two million shares of common stock for issuance, subject to adjustment in the event of a recapitalization in accordance with the terms of the 2008 Plan.

The 2008 Plan authorizes the issuance of awards including stock options, restricted stock units (RSUs), restricted stock, unrestricted stock, stock appreciation rights (SARs) and other equity and/or cash performance incentive awards to employees, directors, and consultants of the Company. Subject to certain restrictions, the Compensation Committee of the Board of Directors has broad discretion to establish the terms and conditions for awards under the 2008 Plan, including the number of shares, vesting conditions and the required service or performance criteria. Options and SARs may have a contractual term of up to ten years and generally vest over three to five years with an exercise price equal to the fair market value on the date of grant. Incentive stock options (ISOs) granted must have an exercise price equal to or greater than the fair market value of the Company’s common stock on the date of grant. Repricing of stock options and SARs is permitted without stockholder approval. If a particular award agreement so provides, certain change in control transactions may cause such awards granted under the 2008 Plan to vest at an accelerated rate, unless the awards are continued or substituted for in connection with the transaction. As of March 31, 2016,  393,141 shares of common stock remained available for issuance pursuant to awards granted under the 2008 Plan.

Exercisable, March 31, 2016		617,407		3.21		6.49

The aggregate intrinsic value of options vested and expected to vest as of March 31, 2016 and December 31, 2015 was approximately $1,000 and $178,000, respectively. Intrinsic value is calculated as the amount by which the current market value of a share of common stock exceeds the exercise price multiplied by the number of option shares.

During the three months ended March 31, 2016, the Company granted options to purchase 190,000 shares to two employees at a weighted average exercise price of $2.66 per share. No employees exercised their options and no options were forfeited or canceled.

During the three months ended March 31, 2015, the Company did not grant any new options to employees. Three employees exercised their options to purchase 3,551 shares of the Company’s common stock. No Options were forfeited or canceled.

The estimated fair value of share-based compensation to employees is recognized on a ratable basis over the requisite service period, which is generally the vesting period of the award.

Restricted Stock Awards Granted to Employees

There were no RSAs granted to employees during the three months ended March 31, 2016.

Total Share-based Compensation Expenses

As of March 31, 2016 the gross amount of unrecognized share-based compensation expense relating to unvested share-based awards held by employees was approximately $484,000, which the Company anticipates recognizing over a weighted average period of 1.81 years.

In connection with the grant of stock options, restricted stock awards and warrants to employees, the Company recorded stock-based compensation expenses of $110,710 and $121,361 for the three-month period ended March 31, 2016 and 2015, respectively.

Earnings per share [Abstract]

Earnings Per Share [Text Block]

18. Loss per share

Basic loss per common share is computed by dividing loss available to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per common share is computed by dividing income available to common stockholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock outstanding that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options and restricted shares. The dilutive effect of potential dilutive securities is reflected in diluted earnings per common share by application of the treasury stock method. Under the treasury stock method, an increase in the fair market value of the Company’s common stock can result in a greater dilutive effect from potentially dilutive securities. The Company excludes potential common stock in the diluted EPS computation in periods of losses from continuing operations, as their effect would be anti-dilutive.

The following table sets forth the computation of basic and diluted earnings per common share for the three months ended March 31, 2016 and 2015.

Diluted earnings per share takes into account the potential dilution that could occur if securities or other contracts to issue common stock were exercised and converted into common stock.

There were 1,716,927 and 1,406,736 options and warrants outstanding as of March 31, 2016 and 2015, respectively, which were not included in the computation of diluted EPS for the periods ended March 31, 2016 and 2015 because of the net loss sustained for the three months ended March 31, 2016 and 2015.

Securities Offering Transaction [Abstract]

Stockholders' Equity Note Disclosure [Text Block]

19. Securities Offering Transaction

In April 2014, the Company and certain institutional investors entered into a securities purchase agreement, pursuant to which the Company sold 1,000,000 shares of common stock and warrants exercisable for 500,000 shares of common stock in a registered direct offering at a price of $5.05 per fixed combination for aggregate proceeds of $5.05 million. The shares and warrants were sold in multiples of a fixed combination consisting of (i) one share of common stock and (ii) one immediately exercisable warrant to purchase 0.50 shares of common stock. The net proceeds from the offering were $4,633,164, after deducting fees due the placement agent and offering expenses.

The warrants have an initial exercise price of $6.33 per share and are exercisable until April 17, 2017. The exercise price of the warrants, and in some cases the number of shares issuable upon exercise of the warrants, will be subject to appropriate adjustment in relation to certain events. In addition, if the Company issues shares in the future at a price below $6.33 per share, the exercise price of the warrants will be reduced to such lower price. No adjustment will be made to the number of shares purchasable in such event.

The warrants were classified as a liability. The aggregate fair value of the warrant liability at issuance dates was $1,173,952. The residual balance of $3,459,212 was allocated to common shares issued.

The fair values of the warrants as of April 17, 2014 were calculated using the Black-Scholes pricing model with the following assumptions:

	April 17,2014
Expected volatility		85.76	%
Risk-free interest rate		0.9	%
Expected term (in years)		3.0
Dividend rate		-
Fair value	$	2.3

The fair value of the warrant liability is re-measured at each reporting period and recorded as a gain or loss on fair value of warrant liability. As of March 31, 2016 and December 31, 2015 the fair value of warrant liability was $21,080 and $140,549, respectively. For the three months ended March 31, 2016 and 2015, the Company recognized a gain of $119,469 and $346,299, respectively, on the change in the fair value of the warrant liability.

The fair values of the warrants as of March 31, 2016 and December 31, 2015 were calculated using the Black-Scholes pricing model with the following assumptions:

	March 31, 2016			December 31,2015
Expected volatility		69.45	%		79.85	%
Risk-free interest rate		0.6	%		0.56	%
Expected term (in years)		1.05			1.30
Dividend rate		-			-
Fair value	$	0.04		$	0.81

In conjunction with the securities offering transaction, the Company issued three year warrants to investment bankers to purchase 40,000 shares of the Company’s common stock at $6.33 per share. The aggregate fair value of the warrants was $94,982, which was recognized as a share-based compensation and resulted in an increase of additional paid-in capital. As such compensation was offering cost, it resulted in a reduction in additional paid-in capital.

Summary of significant accounting policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

Basis of presentation

The accompanying consolidated balance sheet as of December 31, 2015, which has been derived from audited financial statements, and the unaudited interim consolidated financial statements as of March 31, 2016 and for the three ended March 31, 2016 and 2015 have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and disclosures, which are normally included in financial statements prepared in accordance with United States generally accepted accounting principles (U.S. GAAP), have been condensed or omitted pursuant to such rules and regulations. The interim financial information should be read in conjunction with the Financial Statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, previously filed with the SEC on March 29, 2016.

In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present a fair presentation of the Company’s consolidated financial position as of March 31, 2016, its consolidated results of operations and cash flows for the three months ended March 31, 2016 and 2015, as applicable, have been made. The interim results of operations are not necessarily indicative of the operating results for the full fiscal year or any future periods.

Consolidation, Policy [Policy Text Block]

Principles of consolidation

 

The consolidated financial statements include the accounts of Highpower and its subsidiaries. All significant inter-company accounts and transactions have been eliminated in consolidation. Non-controlling interests represent the equity interest in the GZ Highpower that is not attributable to the Company.

Use of Estimates, Policy [Policy Text Block]

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant items subject to such estimates and assumptions include revenues; the allowance for doubtful receivables; recoverability of the carrying amount of inventory; fair values of financial instruments; and the assessment of deferred tax assets or liabilities. These estimates are often based on complex judgments and assumptions that management believes to be reasonable but are inherently uncertain and unpredictable. Actual results could differ significantly from these estimates.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Concentrations of credit risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of accounts receivable. The Company extends credit based on an evaluation of the customer’s financial condition, generally without requiring collateral or other security. In order to minimize the credit risk, the management of the Company has delegated a team responsible for determining credit limits, credit approvals and other monitoring procedures to ensure that follow-up action is taken to recover overdue debts. Further, the Company reviews the recoverable amount of each individual trade debt at each balance sheet date to ensure that adequate impairment losses are made for irrecoverable amounts. In this regard, the management of the Company considers that the Company’s credit risk is significantly reduced.

No customer accounted for 10% or more of total sales during the three months ended March 31, 2016 and 2015.

There was one major supplier that accounted for 14.4% of the total purchase amount during the three months ended March 31, 2016. And no supplier accounted for 10% or more of the total purchase amount during the three months ended March 31, 2015.

There was one major customer that accounted for 11.5% and 11.3% of the accounts receivable as of March 31, 2016 and December 31, 2015, respectively.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash include all cash and deposits in banks with initial maturities of three months or less.

Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]

Restricted cash

Restricted cash include time deposits and cash security for bank acceptance bills included in notes payable.

Receivables, Policy [Policy Text Block]

Accounts receivable

Accounts receivable are stated at the original amount less an allowance for doubtful receivables, if any, based on a review of all outstanding amounts at period end. An allowance is also made when there is objective evidence that the Company will not be able to collect all amounts due according to the original terms of the receivables. Bad debts are written off against the allowance after all collection efforts have ceased. The Company extends unsecured credit to customers in the normal course of business and believes all accounts receivable in excess of the allowances for doubtful receivables to be fully collectible. The Company does not accrue interest on trade accounts receivable.

Finance, Loans and Leases Receivable, Policy [Policy Text Block]

Notes receivable

Notes receivable represent banks’ and commercial acceptances that have been arranged with third-party financial institutions by certain customers to settle their purchases from us. These banks’ acceptances are non-interest bearing and are collectible within one year.

Inventory, Policy [Policy Text Block]

Inventories

Inventories are stated at lower of cost or market. Cost is determined using the weighted average method. Inventory includes raw materials, packing materials, consumables, work in progress and finished goods. The variable production overhead is allocated to each unit of production on the basis of the actual use of the production facilities. The allocation of fixed production overhead to the costs of conversion is based on the normal capacity of the production facilities.

Property, Plant and Equipment, Policy [Policy Text Block]

Property, plant and equipment

Property, plant and equipment, net are stated at cost less accumulated depreciation. Cost represents the purchase price of the asset and other costs incurred to bring the asset into its existing use. Maintenance, repairs and betterments, including replacement of minor items, are charged to expense; major additions to physical properties are capitalized.

Depreciation of property, plant and equipment is provided using the straight-line method over their estimated useful lives at the following annual rates:

Buildings	2.5% -5	%
Furniture, fixtures and office equipment	20	%
Leasehold improvement	Shorter of the remaining lease terms or estimated useful lives
Machinery and equipment	10	%
Motor vehicles	20	%

Upon sale or disposal, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount less proceeds from disposal is charged or credited to income.

Construction in progress represents capital expenditures for direct costs of construction or acquisition and design fees incurred, and the interest expenses directly related to the construction. Capitalization of these costs ceases and the construction in progress is transferred to the appropriate category of property, plant and equipment when substantially all the activities necessary to prepare the assets for their intended use are completed. Construction in progress is not depreciated.

Land Use Rights [Policy Text Block]

Land use rights

Land use rights represent payments for the rights to use certain parcels of land for a certain period of time in the PRC. Land use rights are carried at cost and charged to expense on a straight-line basis over the period the rights are granted.

Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]

Other assets

Other assets represent a royalty-bearing, non-exclusive license to use certain patents owned by an unrelated party ("License Provider"), to manufacture rechargeable nickel metal hydride batteries for portable consumer applications (“Consumer Batteries”) in the PRC, and a royalty-bearing, non-exclusive worldwide license to use certain patents owned by License Provider to manufacture, sell and distribute Consumer Batteries. The value of the licenses was established based on historic acquisition costs.

An exclusive proprietary technology contributed by the four founding management members of GZ Highpower in exchange for the paid-in capital of GZ Highpower is recorded at the four management members’ historical cost basis of $nil.

Revenue Recognition, Deferred Revenue [Policy Text Block]

Government grants

Government grants are recognized when received and all the conditions for their receipt have been met.

Specifically, government grants whose primary condition is that the Company should purchase, construct or otherwise acquire non-current assets is recognized on the consolidated balance sheet as deferred income and subsequently deducted in calculating the carrying amount of the related asset after the purchase, construction or acquisition completed. As of March 31, 2016 and December 31, 2015, the Company recorded deferred income of $861,369 and $879,944, respectively, for the government grants to purchase non-current assets.

Government grants for the purpose of giving immediate financial support to the Company by local government are recognized as other income when received. In the three months ended March 31, 2016 and 2015, $6,669 and $109,295 of government grants were recognized as other income, respectively.

Revenue Recognition, Policy [Policy Text Block]

Revenue recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, the sales price is fixed or determinable, delivery of the product has occurred, title and risk of loss have transferred to the customers and collectability of the receivable is reasonably assured. The majority of domestic sales contracts transfer title and risk of loss to customers upon receipt. The majority of oversea sales contracts transfer title and risk of loss to customers when goods were delivered to the carriers. Revenue is presented net of any sales tax and value added tax.

The Company does not have arrangements for returns from customers and does not have any future obligations directly or indirectly related to product resale by customers. The Company has no sales incentive programs.

Cost of Sales, Policy [Policy Text Block]

Cost of sales

Cost of revenues consists primarily of material costs, employee compensation, depreciation and related expenses, which are directly attributable to the production of products. Write-down of inventories to lower of cost or market is also recorded in cost of revenues.

Research and Development Expense, Policy [Policy Text Block]

Research and development

Research and development expenses include expenses directly attributable to the conduct of research and development programs, including the expenses of salaries, employee benefits, materials, supplies, and maintenance of research equipment. All expenses associated with research and development are expensed as incurred.

Advertising Costs, Policy [Policy Text Block]

Advertising

Advertising, which generally represents the cost of promotions to create or stimulate a positive image of the Company or a desire to buy the Company’s products and services, is expensed as incurred. No significant advertising expense was recorded for the three months ended March 31, 2016 and 2015.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Share-based compensation

The Company recognizes compensation expense associated with the issuance of equity instruments to employees for their services. The fair value of the equity instruments is estimated on the date of grant and is expensed in the financial statements over the vesting period. The input assumptions used in determining fair value are the expected life, expected volatility, risk-free rate and the dividend yield.

Share-based compensation associated with the issuance of equity instruments to non-employees is measured at the fair value of the equity instrument issued or committed to be issued, as this is more reliable than the fair value of the services received. The fair value is measured at the earlier of date that the commitment for performance by the counterparty has been reached or the counterparty's performance is complete.

Income Tax, Policy [Policy Text Block]

Income taxes

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred income taxes are recognized for the tax consequences in future years of differences between the tax bases of assets and liabilities and their financial reporting amounts at each period end based on enacted tax laws and statutory tax rates, applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

Income Tax Uncertainties, Policy [Policy Text Block]

Uncertain tax positions

The Company accounts for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that the Company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized and recorded as necessary in the provision for income taxes. There were no uncertain tax positions as of March 31, 2016 and December 31, 2015.

Comprehensive Income, Policy [Policy Text Block]

Comprehensive loss

Recognized revenue, expenses, gains and losses are included in net income or loss. Although certain changes in assets and liabilities are reported as separate components of the equity section of the consolidated balance sheet, such items, along with net income or loss, are components of comprehensive income or loss. The components of other comprehensive income or loss are consisted solely of foreign currency translation adjustments, net of the income tax effect.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign currency translation and transactions

Highpower’s functional currency is the United States dollar ("US$"). HKHTC's functional currency is the Hong Kong dollar ("HK$"). The functional currency of the Company’s subsidiaries in the PRC is the Renminbi ("RMB").

Most of the Company’s oversea sales are priced and settled with US$. At the date a foreign currency transaction is recognized, each asset, liability, revenue, expense, gain, or loss arising from the transaction is measured initially in the functional currency of the recording entity by use of the exchange rate in effect at that date. The increase or decrease in expected functional currency cash flows upon settlement of a transaction resulting from a change in exchange rates between the functional currency and the currency in which the transaction is denominated is recognized as foreign currency transaction gain or loss that is included in determining net income for the period in which the exchange rate changes. At each balance sheet date, recorded balances that are denominated in a foreign currency are adjusted to reflect the current exchange rate.

The Company’s reporting currency is US$. Assets and liabilities of HKHTC and the PRC subsidiaries are translated at the current exchange rate at the balance sheet dates, revenues and expenses are translated at the average exchange rates during the reporting periods, and equity accounts are translated at historical rates. Translation adjustments are reported in other comprehensive income.

Segment Reporting, Policy [Policy Text Block]

Segment Reporting

The Company uses the “management approach” in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company's chief operating decision maker for making operating decisions and assessing performance as the source for determining the Company's reportable segments. The Company’s reportable segments are based on products, geography, legal structure, management structure, or any other manner in which management disaggregates a company. Therefore the Company categorizes its business into three reportable segments, namely (i) Lithium Batteries; (ii) Ni-MH Batteries; and (iii) New Material.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair value of financial instruments

The carrying values of the Company’s financial instruments, including cash, restricted cash, trade and other receivables, deposits, trade and other payables and bank borrowings, approximate their fair values due to the short-term maturity of such instruments.

The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

The Company establishes a fair value hierarchy that requires maximizing the use of observable inputs and minimizing the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

The Company measures fair value using three levels of inputs that may be used to measure fair value:

-Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

-Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

-Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

Warrant Liabilities Policy [Policy Text Block]

Warrant Liabilities

For warrants that are not indexed to the Company’s stock, the Company records the fair value of the issued warrants as a liability at each balance sheet date and records changes in the estimated fair value as a non-cash gain or loss in the consolidated statement of operations and comprehensive income. The fair values of these warrants have been determined using the Black-Scholes pricing model. The Black-Scholes pricing model provides for assumptions regarding volatility, call and put features and risk-free interest rates within the total period to maturity. These values are subject to a significant degree of judgment on the part of the Company.

Earnings Per Share, Policy [Policy Text Block]

Loss per share

Basic loss per share is computed by dividing loss attributable to holders of common shares by the weighted average number of common shares outstanding during the year. Diluted earnings per share (“EPS”) reflect the potential dilution that could occur if securities or other contracts to issue common shares were exercised or converted into common shares. Potential dilutive securities are excluded from the calculation of diluted EPS in loss periods as their effect would be anti-dilutive.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently issued accounting pronouncements

In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, or ASU 2014-09. This new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to correlate with the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year, while allowing a company to adopt the new revenue standard early but not before the original effective date. This guidance will be effective as to us on January 1, 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. In April 2016, the FASB issued Accounting Standards Update 2016-10, Revenue from Contracts with Customers, or ASU 2016-10. These new standards will identify performance obligations. The Company is currently evaluating the impact of adopting ASU 2014-09 on our consolidated financial statements.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740). To simplify the presentation of deferred income taxes, the amendments in this Update require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in this Update apply to all entities that present a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this Update. For public business entities, the amendments in this Update are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. Under this ASU, inventory will be measured at the “lower of cost and net realizable value” and options that currently exist for “market value” will be eliminated. The ASU defines net realizable value as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” No other changes were made to the current guidance on inventory measurement. ASU 2015-11 is effective for interim and annual periods beginning after December 15, 2016. Early application is permitted and should be applied prospectively. The Company plans to early adopt this standard beginning with the 2016 fiscal year, but does not expect the adoption of this standard to have a material impact on the Company's consolidated financial position, results of operations, or related disclosures.

 

On February 25, 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842). It requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (i.e., January 1, 2019, for a calendar year entity). Early application is permitted for all public business entities and all nonpublic business entities upon issuance. The Company is currently evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements.

In March 2016, the FASB issued Accounting Standards Update (ASU) 2016-09, Compensation—Stock Compensation (Topic 718). Under this update, share-based payment transactions simplified several aspects of the accounting, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas for simplification apply only to nonpublic entities. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. The Company is currently evaluating the impact of adopting ASU 2016-09 on our consolidated financial statements.

We do not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the consolidated financial position, statements of operations and cash flows.
