All significant inter-company balances or transactions have been eliminated on consolidation. The Company has evaluated the relationship with Heilongjiang Shuaiyi, Daqing Shuaiyi and Harbin Shuaiyi and based on the result of the evaluation, believes that these entities are variable interest entities and that it is the primary beneficiary of these entities. Consequently, the Company has included the results of operations of these variable interest entities in the consolidated financial statements. The Company’s relationships with Heilongjiang Shuaiyi, Daqing Shuaiyi and Harbin Shuaiyi are governed by a series of contractual arrangements. Under PRC laws, Heilongjiang Shuaiyi, Daqing Shuaiyi and Harbin Shuaiyi are independent legal persons and none of them is exposed to liabilities incurred by the other parties.

The Company accounts for income taxes in accordance with FASB ASC Topic 740, “Income Taxes”. FASB ASC Topic 740 requires an asset and liability approach for financial accounting and reporting for income taxes and allows recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or that future deductibility is uncertain. The Company’s income tax returns are subject to examination by the Internal Revenue Service (“IRS”) and other tax authorities in the locations where it operates. The Company assesses potentially unfavorable outcomes of such examinations based on the criteria of FASB ASC 740-10-25-5 through 740-10-25-7 and 740-10-25-13 (formerly FASB Interpretation No. 48 (“FIN 48”) “Accounting for Uncertainty in Income Taxes”). The interpretation prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken (or expected to be taken) in a tax return. This Interpretation also provides guidance on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods and income tax disclosures.falsefalsefalsenonnum:textBlockItemTypenaDisclosure of accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 3 -URI http://asc.fasb.org/extlink&oid=6367646&loc=d3e18780-107790 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 10 -URI http://asc.fasb.org/subtopic&trid=2144681 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 30 -URI http://asc.fasb.org/subtopic&trid=2144749 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 10 -Section 50 -Paragraph 19 -URI http://asc.fasb.org/extlink&oid=6907707&loc=d3e32840-109319 Reference 5: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 954 -SubTopic 740 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6491622&loc=d3e9504-115650 Reference 6: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 10 -Section 50 -Paragraph 17 -Subparagraph (b) -URI http://asc.fasb.org/extlink&oid=6907707&loc=d3e32809-109319 Reference 7: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 10 -Section 45 -Paragraph 25 -URI http://asc.fasb.org/extlink&oid=21917399&loc=d3e32247-109318 Reference 8: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 10 -Section 45 -Paragraph 28 -URI http://asc.fasb.org/extlink&oid=21917399&loc=d3e32280-109318 false0Income taxes [Policy Text Block]14false 4us-gaap_ResearchDevelopmentAndComputerSoftwarePolicyTextBlockus-gaap_truenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00 Research and development costs Research and development costs are expensed as incurred, and are charged to general and administrative expenses.

For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. This would be the case when a portion of the amount reclassified out of accumulated other comprehensive income is reclassified to a balance sheet account (for example, inventory) instead of directly to income or expense in the same reporting period. For public entities, the amendments are effective prospectively for reporting periods beginning after December 15, 2012. The adoption of this update did not have a significant impact on its consolidated financial statements. In March 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2013-05, Foreign Currency Matters, (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (ASU 2013-05), to resolve a diversity in accounting for the cumulative translation adjustment of foreign currency upon derecognition of a foreign subsidiary or group of assets. ASU 2013-05 requires the parent to apply the guidance in Subtopic 830-30 to release any related cumulative translation adjustment into net income when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets within a foreign entity. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. Further, ASU 2013-05 clarified that the parent should apply the guidance in subtopic 810-10 if there is a sale of an investment in a foreign entity, including both (1) events that result in the loss of a controlling financial interest in a foreign entity and (2) events that result in an acquirer obtaining control of an acquiree in which it held an equity interest immediately before the acquisition date. Accordingly, the cumulative translation adjustment should be released into net income upon the occurrence of those events. ASU 2013-05 is effective prospectively for the Company in our first quarter of fiscal 2014, with early adoption permitted. The Company does not expect ASU 20 13-05 to have a significant impact on its consolidated result of operations and financial condition. In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740)(ASU 2013-11). The amendments in this update provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, similar tax loss, or tax credit carryforward exists. These amendments provide that an unrecognized tax benefit, or a portion thereof, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent that a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented as a liability. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The Company does not expect ASU 2013-11 to have a significant impact on its consolidated result of operations and financial condition. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s consolidated financial statements upon adoption.falsefalsefalsenonnum:textBlockItemTypenaDisclosure of accounting policy pertaining to new accounting pronouncements that may impact the entity's financial reporting.
