Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Sep. 30, 2012
Principles of Consolidation [Policy Text Block] |
(a) | Principles of Consolidation
| The consolidated financial statements include the financial statements of the Company and its subsidiaries. All significant inter-company balances and transactions have been eliminated prior to consolidation.
Cash and Cash Equivalents [Policy Text Block] |
(b) | Cash and Cash Equivalents
| Cash consists of cash on hand and in banks. The Company considers all highly liquid debt instruments, with initial terms of less than three months to be cash equivalents. As of September 30, 2011 and 2012, there were no cash equivalents.
Trade Accounts Receivable [Policy Text Block] |
(c) | Trade Accounts Receivable
| Trade accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts and sales returns. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing trade accounts receivable. The Company determines the allowance based on historical write-off experience, customer specific facts and economic conditions. Bad debt expense is included in general and administrative expenses.
| Outstanding accounts receivable balances are reviewed individually for collectability. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. To date, the Company has charged off US$15,627,742 from its outstanding accounts receivable balance as of September 30, 2012. The Company does not have any off-balance-sheet credit exposure to its customers, except for outstanding bills receivable discounted with banks (see note 23) that are subject to recourse for non-payment.
Inventories [Policy Text Block] |
(d) | Inventories
| Inventories are stated at the lower of cost or market. The cost of inventories is determined using weighted average cost method, and includes expenditure incurred in acquiring the inventories and bringing them to their existing location and condition. In case of finished goods and work in progress, cost includes an appropriate share of production overhead based on normal operating capacity.
| The Company regularly reviews the cost of inventories against their estimated fair market value and records a lower of cost or market write-down for inventories that have costs in their excess of estimated market value.
Property, Plant and Equipment [Policy Text Block] |
(e) | Property, Plant and Equipment
Property, plant and equipment (except construction in progress) are stated at cost less accumulated depreciation and impairment charge. Depreciation is calculated based on the straight-line method (after taking into account their respective estimated residual values) over the estimated useful lives of the assets as follows:
Lease Prepayments [Policy Text Block] |
(f) | Lease Prepayments
| Lease prepayments represent the cost of land use rights in the PRC. Land use rights are carried at cost and amortized on a straight-line basis over the period of rights of 50 years.
Foreign Currency Transactions and Translations PForeign Currency Transactions and Translationolicy [Policy Text Block] |
(g) | Foreign Currency Transactions and Translation
| The reporting currency of the Company is the United States dollar (“US dollar”). Transactions denominated in currencies other than US dollar are translated into US dollar at the average rates for the period. Monetary assets and liabilities denominated in currencies other than US dollar are translated into US dollar at the rates of exchange ruling at the balance sheet date. The resulting exchange differences are recorded in finance costs in the statement of operations and comprehensive loss.
The financial records of the Company’s operating subsidiaries are maintained in their local currency, the Renminbi (“RMB”), which is the functional currency. Assets and liabilities are translated at the exchange rates at the balance sheet date, equity accounts are translated at historical exchange rates, and income and expenses items are translated using the average rate for the period. The translation adjustments are recorded in accumulated other comprehensive income under shareholders’ equity.
| RMB is not a fully convertible currency. All foreign exchange transactions involving RMB must take place either through the People’s Bank of China (the “PBOC”) or other institutions authorized to buy and sell foreign exchange. The exchange rates adopted for the foreign exchange transactions are the rates of exchange quoted by the PBOC, which are determined largely by supply and demand. Translation of amounts from RMB into US dollar has been made at the following exchange rates for the respective years:
Intangible Assets [Policy Text Block] |
(h) | Intangible Assets
| Intangible assets are stated in the balance sheet at cost less accumulated amortization. The costs of the intangible assets are amortized on a straight-line basis over their estimated useful lives. The respective amortization periods for the intangible assets are as follows:
Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [PImpairment of Long-lived Assetsolicy Text Block] [Policy Text Block] |
(i) | Impairment of Long-lived Assets
| Long-lived assets, which include property, plant and equipment, lease prepayment and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
| Recoverability of long-lived assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.
Revenue Recognition [Policy Text Block] |
(j) | Revenue Recognition
| The Company recognizes revenue on product sales when products are delivered and the customer takes ownership and assumes risk of loss, collection of the relevant receivable is probable, persuasive evidence of an arrangement exists and the sales price is fixed or determinable.
| Net sales of products represent the invoiced value of goods sold, net of value added taxes (“VAT”), sales returns, trade discounts and allowances. The Company is subject to VAT which is levied on the majority of the products of Shenzhen BAK, BAK Electronics and BAK Tianjin at the rate of 17% on the invoiced value of sales. Output VAT is borne by customers in addition to the invoiced value of sales and input VAT is borne by the Company in addition to the invoiced value of purchases to the extent not refunded for export sales. Provision for sales returns are recorded as a reduction of revenue in the same period that revenue is recognized. The provision for sales returns, which is based on historical sales returns data, is the Company’s best estimate of the amount of goods that will be returned from its customers.
Cost of Revenues [Policy Text Block] |
(k) | Cost of Revenues
| 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 and market is also recorded in cost of revenues.
Income Taxes [Policy Text Block] |
(l) | Income Taxes
| Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets are reduced by a valuation allowance to the extent management concludes it is more likely than not that the assets will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the statement of operations and comprehensive loss in the period that includes the enactment date.
Research and Development and Advertising Expenses [Policy Text Block] |
(m) | Research and Development and Advertising Expenses
| Research and development and advertising expenses are expensed as incurred. Research and development expenses consist primarily of remuneration for research and development staff, depreciation and maintenance expenses of research and development equipment and material costs for research and development. Advertising expenses, included in sales and marketing expenses, amounted to US$33,482 and US$236,415 for the years ended September 30, 2011 and 2012 respectively.
Bills Payable [Policy Text Block] |
(n) | Bills Payable
| Bills payable represent bills issued by financial institutions to the Company’s vendors. The Company’s vendors receive payments from the financial institutions directly upon maturity of the bills and the Company is obliged to repay the face value of the bills to the financial institutions.
Government Grants [Policy Text Block] |
(o) | Government Grants
| Receipts of government grants to encourage research and development activities which are non-refundable are credited to deferred income upon receipt. The grants are used for purchases of assets, to subsidize the research and development expenses incurred, for compensating expenses already incurred or for good performance of the Company.
| Grants applicable to land are amortized over the life of the depreciable facilities constructed on it. For research and development expenses, the Company matches and offsets the government grants with the expenses of the research and development activities as specified in the grant approval document in the corresponding period when such expenses are incurred. Government grants received as compensation for expenses already incurred are recognized as income in the period they become recognizable.
| No government grants were offset against finance costs for the years ended September 30, 2011 and 2012. Government grants recorded as deferred revenue and included in accrued expenses and other payables (Note 13(b)) amounted to US$720,518 and US$882,161 as of September 30, 2011 and 2012, respectively.
| During the year ended September 30, 2011, the Company recorded government grant income of US$1,453,727. US$1,209,546 of the grant was received to reward the Company’s research on the special lithium battery projects of China and US$244,181 represented amortization of government subsidies received in relation to the additional cost of land use rights of BAK Industrial Park (Notes 15 and 16).
| During the year ended September 30, 2012, the Company recorded government grant income of US$5,353,554, of which US$5,101,085 was received to reward the Company’s research on the special lithium battery projects of China and US$252,469 represented amortization of government subsidies received in relation to the additional cost of land use rights of BAK Industrial Park (Notes 15 and 16).
Share-based Compensation [Policy Text Block] |
(p) | Share-based Compensation
| The Company adopted the provisions of ASC Topic 718 which requires the Company to measure and recognize compensation expenses for an award of equity instrument based on the grant-date fair value. The cost is recognized over the vesting period (or the requisite service period). ASC Topic 718 also requires the Company to measure the cost of a liability-classified award based on its current fair value. The fair value of the award will be remeasured subsequently at each reporting date through the settlement date. Changes in fair value during the requisite service period are recognized as compensation cost over that period. Further, ASC Topic 718 requires the Company to estimate forfeitures in calculating the expense related to stock-based compensation.
| The fair value of each option award is estimated on the date of grant using the Black-Scholes Option Valuation Model. The expected volatility was based on the historical volatilities of the Company’s listed common stocks in the United States and other relevant market information. The Company uses historical data to estimate share option exercises and employee departure behavior used in the valuation model. The expected terms of share options granted is derived from the output of the option pricing model and represents the period of time that share options granted are expected to be outstanding. Since the share options once exercised will primarily trade in the U.S. capital market, the risk-free rate for periods within the contractual term of the share option is based on the U.S. Treasury yield curve in effect at the time of grant.
Retirement and Other Post-retirement Benefits [Policy Text Block] |
(q) | Retirement and Other Post-retirement Benefits
| Contributions to retirement schemes (which are defined contribution plans) are charged to cost of revenues, research and development expenses, sales and marketing expenses and general and administrative expenses in the statement of operations and comprehensive loss as and when the related employee service is provided.
Loss per share [Policy Text Block] |
(r) | Loss per Share
| Basic loss per share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the year. Diluted loss per share is computed by dividing net loss by the sum of the weighted average number of ordinary shares outstanding and dilutive potential ordinary shares during the year. The effects of common stock equivalents that are anti-dilutive are excluded from the dilutive loss per share calculations.
Use of Estimates [Policy Text Block] |
(s) | Use of Estimates
| The preparation of the consolidated financial statements in accordance with US GAAP requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the recoverability of the carrying amount of long-lived assets; valuation allowance for obsolete inventories, receivables and deferred tax assets; provision for sales returns; valuation of share-based compensation expense; and fair value assessment of financial guarantees. Actual results could differ from those estimates.
Segment Reporting [Policy Text Block] |
(t) | 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. Management, including the chief operating decision maker, reviews operating results solely by monthly revenue of Li-ion rechargeable batteries (but not by sub-product type or geographic area) and operating results of the Company and, as such, the Company has determined that the Company has one operating segment as defined by ASC Topic 280 “Segment Reporting”.
Commitments and Contingencies [Policy Text Block] |
(u) | Commitments and Contingencies
| Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment can be reasonably estimated.
Recently Issued Accounting Standards [Policy Text Block] |
(v) | Recently Issued Accounting Standards
In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2011-04, “Fair Value Measurements (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (“ASU 2011-04”). ASU 2011-04 changes the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements to ensure consistency between U.S. GAAP and IFRS. This standard also expands the disclosure requirements particularly for level 3 fair value measurements. This standard is effective on a prospective basis for reporting periods beginning on or after December 15, 2011. The Company is currently evaluating what impact, if any, this standard will have on its consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (“ASU 2011-05”). ASU 2011-05 eliminates the option to report other comprehensive income and its components in the statement of changes in equity. Under this standard, an entity can elect to present items of net income and other comprehensive income in one continuous statement of comprehensive income or in two separate but consecutive statements. This new guidance is to be applied retrospectively for fiscal years, and for interim periods within those years, beginning after December 15, 2011. The Company is currently evaluating what impact, if any, this standard will have on its consolidated financial statements. In September 2011, the FASB issued ASU 2011-08, “Intangibles-Goodwill and Other (Topic 350)”. The amendments in this update will allow an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under these amendments, an entity would not be required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amendments include a number of events and circumstances for an entity to consider in conducting the qualitative assessment. The amendments in this ASU are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. The Company is currently evaluating what impact, if any, this standard will have on its consolidated financial statements. In September 2011, the FASB issued ASU 2011-09, “Compensation-Retirement Benefits – Multiemployer Plans (Subtopic 715 - 80)”. The amendments in this update require additional disclosures about an employer’s participation in a multiemployer plan. ASU 2011-09 is effective for annual periods for fiscal years ending after December 15, 2011, and early adoption is permitted. ASU 2011-09 should be applied retrospectively for all prior periods presented. The adoption of this ASU update has no material impact on the Company’s consolidated financial statements. In December 2011, the FASB issued ASU 2011-11, “Balance Sheet (Topic 210)”. The objective of this update is to provide enhanced disclosures that will enable users of its financial statements to evaluate the effect or potential effect of netting arrangements on an entity’s financial position. This includes the effect or potential effect of rights of setoff associated with an entity’s recognized assets and recognized liabilities within the scope of this update. The amendments require enhanced disclosures by requiring improved information about financial instruments and derivative instruments that are either (1) offset in accordance with either Section 210-20-45 or Section 815-10-45 or (2) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in accordance with either Section 210-20-45 or Section 815-10-45. An entity is required to apply the amendments retrospectively for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The Company is currently evaluating what impact, if any, this standard will have on its consolidated financial statements. In December 2011, the FASB issued ASU 2011-12 “Comprehensive Income (Topic 220)”. The amendments in this update supersede certain pending paragraphs in Accounting Standards Update No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income”, to effectively defer only those changes in Update 2011-05 that relate to the presentation of reclassification adjustments out of accumulated other comprehensive income. The amendments will be temporary to allow time to redeliberate the presentation requirements for reclassifications out of accumulated other comprehensive income for annual and interim financial statements for public, private, and non-profit entities. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. Early application by public entities is permitted. The Company is currently evaluating what impact, if any, this standard will have on its consolidated financial statements. In July 2012, the FASB issued ASU 2012-02 on impairment testing for indefinite-lived intangible assets. This ASU amends FASB Codification Topic 350, Intangibles-Goodwill and Other, to allow, but not require, an entity, when performing its annual or more frequent indefinite-lived intangible asset impairment test, to first assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired then, the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted. The Company is currently evaluating what impact, if any, this standard will have on its consolidated financial statements.
