Summary of significant accounting policies [Text Block] | Note 2 – Summary of significant accounting policies Liquidity In assessing the Company’s liquidity, the Company monitors and analyzes its cash on-hand and its operating and capital expenditure commitments. The Company’s liquidity needs are to meet its working capital requirements, operating expenses and capital expenditure obligations. The Company engages in the production of advanced construction materials for large scale infrastructure, commercial and residential developments. The Company’s business is capital intensive and the Company is highly leveraged. Debt financing in the form of short term bank loans, loans from related parties and bank acceptance notes have been utilized to finance the working capital requirements and the capital expenditures of the Company. Due to recurring losses, the Company’s working capital was approximately $6.9 million as of March 31, 2017, as compared to $16.4 million as of June 30, 2016. As of March 31, 2017, the Company had cash on-hand of approximately $1.4 million and restricted cash balances of approximately $3.9 million, with remaining current assets mainly composed of accounts receivables and prepayments and advances. Although the Company believes that it can realize its current assets in the normal course of business, the Company’s ability to repay its current obligations will depend on the future realization of its current assets. Management has considered its historical experience, the economic environment, trends in the construction industry, the expected collectability of its accounts receivable and other receivables and the realization of the prepayments on inventory, and provided for an allowance for doubtful accounts as of March 31, 2017. The Company expects to realize the balance of its current assets net of the allowance for doubtful accounts within the normal operating cycle of a twelve month period. If the Company is unable to realize its current assets within the normal operating cycle of a twelve month period, the Company may have to consider supplementing its available sources of funds through the following: • Financial support and credit guarantee commitments from the Company’s majority shareholders (See Note 7 - Related party transactions). • Other available sources of financing from PRC banks and other financial institutions, given the Company’s credit history. Based on the above considerations, the Company’s management is of the opinion that it has sufficient funds to meet the Company’s working capital requirements and debt obligations as they become due. However, there is no assurance that management will be successful in their plans. There are a number of factors that could potentially arise that could undermine the Company’s plans, such as changes in the demand for the Company’s products, economic conditions, competitive pricing in the concrete-mix industry, the Company’s operating results continuing to deteriorate, or the inability of the Company’s bank and shareholders to provide continued financial support. Basis of presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These financial statements include the accounts of all the directly and indirectly owned subsidiaries and VIEs listed below. All material intercompany transactions and balances have been eliminated in consolidation. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary to give a fair presentation have been included. Interim results are not necessarily indicative of results of a full year. The information in this Form 10-Q should be read in conjunction with information included in the annual report for the fiscal year ended June 30, 2016 on Form 10-K filed with the SEC on September 28, 2016. Principles of consolidation The unaudited condensed consolidated financial statements reflect the activities of the following subsidiaries and VIEs. All material intercompany transactions have been eliminated. Ownership Subsidiaries and VIEs Place incorporated percentage BVI-ACM British Virgin Island 100% China-ACMH Beijing, China 100% Xin Ao Beijing, China VIE Heng Yuan Zheng Ke*** Beijing, China VIE Hong Sheng An** Beijing, China VIE Heng Tai**** Beijing, China VIE Da Tong* Datong, China VIE Heng Xin** Luanxian, China VIE *Dissolved in August 2016 ** Dissolved in December 2016 *** Dissolved in January 2017 **** Dissolved in February 2017 VIEs are generally entities that lack sufficient equity to finance their activities without additional financial support from other parties or whose equity holders lack adequate decision making ability. All VIEs with which the Company is involved must be evaluated to determine the primary beneficiary of the risks and rewards of the VIEs. The primary beneficiary is required to consolidate the VIEs for financial reporting purposes. Management makes ongoing assessments of whether China ACM is the primary beneficiary of Xin Ao. Based upon a series of contractual arrangements, the Company determined that Xin Ao is a VIE subject to consolidation and that China ACM is the primary beneficiary. Accordingly, the accounts of Xin Ao are consolidated with those of China ACM. The carrying amount of the VIE’s assets and liabilities are as follows: March 31, June 30, 2017 2016 Current assets $ 83,167,372 $ 90,518,451 Property, plants and equipment 3,714,745 4,709,794 Total assets 86,882,117 95,228,245 Liabilities (74,066,412 ) (72,579,677 ) Intercompany payables* (6,971,710 ) (7,355,650 ) Total liabilities (81,038,122 ) (79,935,327 ) Net assets $ 5,843,995 $ 15,292,918 * Payables to China-ACMH and BVI-ACM have been eliminated upon consolidation. Use of estimates and assumptions The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. The significant estimates and assumptions made in the preparation of the Company’s unaudited condensed consolidated financial statements include allowance for doubtful accounts, deferred income taxes, prepayments and advances, stock-based compensation, and fair value and useful lives of property, plant and equipment. Actual results could be materially different from those estimates. Foreign currency translation The reporting currency of the Company is the U.S. dollar. The functional currency of China ACM and BVI-ACM is the U.S. dollar. China-ACMH and Xin Ao use their local currency Chinese Renminbi (“RMB”) as their functional currency. In accordance with the US GAAP guidance on Foreign Currency Translation, the Company’s results of operations and cash flows are translated at the average exchange rates during the period, assets and liabilities are translated at the exchange rates at the balance sheet dates, and equity is translated at historical exchange rates. As a result, amounts related to assets and liabilities reported on the consolidated statements of cash flows will not necessarily agree with changes in the corresponding balances on the consolidated balance sheets. Asset and liability accounts at March 31, 2017, and June 30, 2016, were translated at RMB6.89 to $1.00 and RMB6.64 to $1.00, respectively. The average translation rates applied to the consolidated statements of operations and comprehensive loss for the three months ended March 31, 2017, and 2016 were RMB6.89 and RMB6.54 to $1.00, respectively. The average translation rates applied to the consolidated statements of operations and comprehensive loss and cash flows for the nine months ended March 31, 2017, and 2016 were RMB6.79 and RMB6.40 to $1.00, respectively. Translation gains (losses) that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in the results of operations. There were no foreign currency transaction gains or losses for each of the three and nine months ended March 31, 2017, and 2016. The effects of foreign currency translation adjustments are included in shareholders’ equity as a component of accumulated other comprehensive income. Revenue recognition Revenue is realized or realizable and earned when four criteria are met: • Persuasive evidence of an arrangement exists (the Company considers its sales contracts to be pervasive evidence of an arrangement); • Delivery has occurred; • The seller’s price to the buyer is fixed or determinable; and • Collectability of payment is reasonably assured. The Company sells its concrete products primarily to major local construction companies. Sales agreements are signed with each customer. The agreements list all terms and conditions with the exception of delivery date and quantity, which are evidenced separately in purchase orders. The purchase price of products is fixed in the agreement and customers are not permitted to renegotiate after the contracts have been signed. The agreements include a cancellation clause if the Company or customers breach the contract terms specified in the agreement. The Company recognizes revenue when title and ownership of the goods are transferred upon shipment to the customer by the Company and collectability of payment is reasonably assured. The Company includes the shipping and handling fee in both revenue and cost of revenue. Financial instruments US GAAP regarding fair value of financial instruments and related fair value measurements define fair value, establish a three-level valuation hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs are defined as follows: Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets; Level 2 inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument; Level 3 inputs to the valuation methodology are unobservable. Financial instruments included in current assets and current liabilities are reported in the unaudited condensed consolidated balance sheets at face value or cost, which approximate fair value because of the short period of time between the origination of such instruments and their expected realization and their current market rates of interest. Cash and cash equivalents The Company considers all highly liquid investments with the original maturity of three months or less at the date of purchase to be cash equivalents. The Company currently maintains substantially all of its day-to-day operating cash balances with major financial institutions within the PRC and the United States. As of March 31, 2017, and June 30, 2016, the Company had deposits in excess of federally insured limits totaling approximately $1.2 million and $0.9 million, respectively, in the PRC. Restricted cash As of March 31, 2017, and June 30, 2016, restricted cash consisted of collateral representing cash deposits for bank guarantees and notes payable. Accounts and notes receivable The Company extends unsecured credit to its customers in the normal course of business. Accounts are considered past due after 30 days. In establishing the required allowance for doubtful accounts, management considers historical experience, the economic environment, trends in the construction industry and the expected collectability of the overdue receivables. Management reviews its accounts receivable each reporting period to determine if the allowance for doubtful accounts is adequate. An estimate for doubtful accounts is recorded when collection of the full amount is no longer probable. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovering is considered remote. The Company provides a provision of 15% of the allowance for doubtful accounts for accounts receivable balance that are past due more than 180 days but less than one year, 40% of the allowance for doubtful accounts for accounts receivable past due from one to two years, 75% of the allowance for doubtful accounts for accounts receivable past due beyond two years, 100% of the allowance for doubtful accounts for accounts receivable past due beyond three years, plus additional amounts as necessary, which the Company’s collection department had determined the collection of the full amount is remote with the approval from the Company’s management to provide 100% of the allowance for doubtful accounts. The Company’s management has continued to evaluate the reasonableness of the valuation allowance policy and will update it if necessary. Notes receivable represent trade accounts receivable from various customers where the customers' banks have guaranteed such customers’ obligation. The notes are non-interest bearing and typically have a three or six month maturity date. The Company has the ability to submit requests for payment to a customer's bank earlier than the scheduled maturity date, subject to a discount on interest charged and a processing fee. Inventories Inventories consist of raw materials and are stated at the lower of cost or market, as determined using the weighted average cost method. Management compares the cost of inventories with the market value and an allowance is made for writing down the inventory to its market value, if lower than cost. As of March 31, 2017, and June 30, 2016, the Company determined that no reserves for obsolescence were necessary. Other receivables Other receivables primarily include prepayments to be refunded by our suppliers if the supplies do not meet the Company’s specification needs, advances to employees, amounts due from unrelated entities, VAT tax refunds and other deposits. Management regularly reviews the aging of receivables and changes in payment trends and records allowances when management believes collection of amounts due are at risk. Accounts considered uncollectible are written off against allowances after exhaustive efforts at collection are made. The Company provides a provision of 5% of the allowance for doubtful accounts for other receivables balance that are aged within one year, 50% of the allowance for doubtful accounts for other receivables aged from one to two years, and 100% of the allowance for doubtful accounts for other receivables aged beyond two years. Prepayments and advances Prepayments are funds deposited or advanced to outside vendors for future inventory purchases. As is standard practice in the PRC, many of the Company’s vendors require a certain amount to be deposited with them as a guarantee that the Company will complete its purchases on a timely basis. This amount is refundable and bears no interest. The Company has legally binding contracts with its vendors, which require any outstanding prepayments to be returned to the Company when such contracts end. The Company recovered approximately $18,000 and wrote off $0.2 million on unrealizable prepayments for the three and nine months ended March 31, 2017, respectively. Property, plants and equipment Property, plants and equipment are stated at cost. Expenditures for maintenance and repairs are charged to operations as incurred while additions, renewals and improvements are capitalized. Depreciation is provided over the estimated useful life of each class of depreciable assets and is computed using the straight-line method with a 5% residual value. Leasehold improvements are amortized over the lesser of estimated useful lives or lease terms, as appropriate. The estimated useful lives of assets are as follows: Useful life Transportation equipment 7 - 10 years Plants and machinery 10 years Office equipment 5 years Buildings and improvements 3 - 20 years Accounting for long-lived assets The Company classifies its long-lived assets into: (i) machinery and equipment; (ii) transportation equipment; (iii) office and equipment; and (iv) buildings and improvements. Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of such assets may not be fully recoverable. It is possible that these assets could become impaired as a result of technological or other industry changes. If circumstances require a long-lived asset or asset group to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques, including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. If the value of an asset is determined to be impaired, the impairment to be recognized is measured in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or the fair value, less disposition costs. Due to recurring losses, the deterioration of the concrete-mix industry in Beijing, PRC, and competitive pricing pressures, the Company has performed an impairment analysis and determined its long-lived assets were impaired during the year ended June 30, 2016. As a result, the Company recorded an impairment charge of $2.6 million for the year ended June 30, 2016. These charges were related to the impairment of the Company’s transportation equipment, plants and machinery. The loss was determined using Level 3 inputs. There were no impairment charges for the three and nine months ended March 31, 2017 and 2016. Competitive pricing pressures and changes in interest rates could materially and adversely affect the Company’s estimates of future net cash flows to be generated by the long-lived assets, and thus could result in future impairment losses. Stock-based compensation The Company records stock-based compensation expense at fair value on the grant date and recognizes the expense over the employee's requisite service period. The Company’s expected volatility assumption is based on the historical volatility of Company’s stock. The expected life assumption is primarily based on historical exercise patterns and employee post-vesting termination behavior. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The expected dividend yield is based on the Company’s current and expected dividend policy. Income taxes The Company accounts for income taxes in accordance with ASC 740, “Income Taxes,” which requires the Company to use the assets and liability method of accounting for income taxes. Under the assets and liability method, deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between financial statement carrying amounts and the tax bases of existing assets and liabilities and operating loss and tax credit carry forwards. Under this accounting standard, the effect on deferred income taxes of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized if it is more likely than not that some portion, or all of, a deferred tax asset will not be realized. ASC 740-10, “Accounting for Uncertainty in Income Taxes,” defines uncertainty in income taxes and the evaluation of a tax position as a two-step process. The first step is to determine whether it is more likely than not that a tax position will be sustained upon examination, including the resolution of any related appeals or litigation based on the technical merits of that position. The second step is to measure a tax position that meets the more-likely-than-not threshold to determine the amount of benefit to be recognized in the financial statements. A tax position is measured at the largest amount of benefit that is greater than 50 percent likelihood of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent period in which the threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not criteria should be de-recognized in the first subsequent financial reporting period in which the threshold is no longer met. Penalties and interest incurred related to underpayment of income tax are classified as income tax expense in the period incurred. United States federal, state and local income tax returns prior to 2013 are not subject to examination by any applicable tax authorities. Value Added Tax Enterprises or individuals who sell commodities, engage in repair and maintenance, or import and export goods in the PRC are subject to a value added tax. The standard VAT rate for the Company’s industry is 3% of gross sales. Research and development Research and development costs are expensed as incurred. The cost of materials and equipment that are acquired or constructed for research and development activities, and have alternative future uses, either in research and development, marketing, or sales, are classified as property and equipment, and depreciated over their estimated useful lives. Earnings (loss) per share The Company reports earnings (losses) per share in accordance with the US GAAP, which requires presentation of basic and diluted earnings (losses) per share in conjunction with the disclosure of the methodology used in computing such earnings per share. Basic earnings (losses) per share excludes dilution and is computed by dividing income (loss) available to common shareholders by the weighted average common shares outstanding during the period. Diluted earnings per share takes into account the potential dilution that could occur if securities or other contracts, such as warrants, options, restricted stock based grants and convertible preferred stock, to issue common stock were exercised and converted into common stock. Common stock equivalents having an anti-dilutive effect on earnings per share are excluded from the calculation of diluted earnings per share.. Stock dividends or stock splits are to be accounted for retroactively if the stock dividends or stock splits occur during the period, or retroactively if the stock dividends or stock splits occur after the end of the period but before the release of the financial statements, by considering if outstanding of the entirety of each period presented. Dilution is computed by applying the treasury stock method. Under this method, options and warrants are assumed to be exercised at the beginning of the period (or at the time of issuance, if later), and as if funds obtained thereby were used to purchase common stock at the average market price during the period. Comprehensive income (loss) Comprehensive income (loss) consists of net income (loss) and foreign currency translation adjustments. Recent Accounting Pronouncements In August 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments provide guidance on the following eight specific cash flow issues: (1) Debt Prepayment or Debt Extinguishment Costs; (2) Settlement of Zero-Coupon Debt Instruments or Other Debt Instruments with Coupon Interest Rates That Are Insignificant in Relation to the Effective Interest Rate of the Borrowing; (3) Contingent Consideration Payments Made after a Business Combination; (4) Proceeds from the Settlement of Insurance Claims; (5) Proceeds from the Settlement of Corporate-Owned Life Insurance Policies, including Bank-Owned; (6) Life Insurance Policies; (7) Distributions Received from Equity Method Investees; (8) Beneficial Interests in Securitization Transactions; and Separately Identifiable Cash Flows and Application of the Predominance Principle. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The amendments should be applied using a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. Management does not believe the adoption of this ASU would have a material effect on the Company’s unaudited condensed consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-17, Consolidation (Topic 810): Interests held through related parties that are under common control. The amendments in this ASU require that the reporting entity, in determining whether it satisfies the second characteristic of a primary beneficiary, to include all of its direct variable interests in a VIE and, on a proportionate basis, its indirect variable interests in a VIE held through related parties, including related parties that are under common control with the reporting entity. The amendments are effective for public business entities for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. For all other entities, the amendments in this ASU are effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. Management does not believe the adoption of this ASU would have a material effect on the Company’s consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows: Restricted Cash". The amendments address diversity in practice that exists in the classification and presentation of changes in restricted cash on the statement of cash flows. The amendment is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Management believes that the adoption of this ASU on the Company’s statement of cash flows will increase cash and cash equivalents by the amount of the restricted cash on the Company’s unaudited condensed consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the definition of a business. The amendments in this ASU is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The amendments are effective for public business entities for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. For all other entities, the amendments in this ASU are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. The Company does not believe the adoption of this ASU would have a material effect on the Company’s consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting, which amends the scope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. For all entities, this ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period. The Company does not expect that the adoption of this guidance will have a material impact on the Company’s unaudited condensed consolidated financial statements. Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications have no effect on the accompanying unaudited condensed consolidated financial statements. |
