Summary of significant accounting policies | Note 2 – Summary of significant accounting policies Basis of presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary to make the financial statements not misleading have been included. Operating results for the three months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the fiscal year ending June 30, 2016. The information included in this Form 10-Q should be read in conjunction with the “Management’s Discussion and Analysis” section, and the financial statements and notes thereto, included in the Annual Report. Principles of consolidation The accompanying unaudited consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The unaudited consolidated financial statements include the financial statements of the Company, its wholly-owned subsidiaries – Top Favour and Hongyuan, and its VIEs – Hongli and its subsidiaries. All significant inter-company transactions and balances between the Company, its subsidiaries and VIEs are eliminated upon consolidation. 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 are evaluated to determine the primary beneficiary of the risks and rewards of the VIE. The primary beneficiary is required to consolidate the VIE for financial reporting purposes. As a result of the contractual arrangements described below, the Company, through Hongyuan, is obligated to absorb a majority of the risk of loss from Hongli’s activities and the Company is enabled to receive a majority of Hongli’s expected residual returns. The Company accounts for Hongli as a VIE and is the primary beneficiary. The primary beneficiary is required to consolidate the VIE for financial reporting purposes. Management makes ongoing assessments of whether Hongyuan is the primary beneficiary of Hongli and its subsidiaries. Accounting Standards Codification (“ASC”) 810 – “Consolidation” addresses whether certain types of entities referred to as VIEs, should be consolidated in a company’s consolidated financial statements. The contractual arrangements entered into between Hongyuan and Hongli comprises the following series of agreements: (1) a Consulting Services Agreement, through which Hongyuan has the right to advise, consult, manage and operate Hongli and its subsidiaries (“the Operating Companies”), collect, and own all of the respective net profits of the Operating Companies; (2) an Operating Agreement, through which Hongyuan has the right to recommend director candidates and appoint the senior executives of the Operating Companies, approve any transactions that may materially affect the assets, liabilities, rights or operations of the Operating Companies, and guarantee the contractual performance by the Operating Companies of any agreements with third parties, in exchange for a pledge by the Operating Companies of their respective accounts receivable and assets; (3) a Proxy Agreement, under which the equity holders of the Operating Companies have vested their voting control over the Operating Companies to Hongyuan and will only transfer their equity interests in the Operating Companies to Hongyuan or its designee(s); (4) an Option Agreement, under which the equity holders of the Operating Companies have granted Hongyuan the irrevocable right and option to acquire all of its equity interests in the Operating Companies, or, alternatively, all of the assets of the Operating Companies; and (5) an Equity Pledge Agreement, under which the equity holders of the Operating Companies have pledged all of their rights, title and interest in the Operating Companies to Hongyuan to guarantee the Operating Companies’ performance of their respective obligations under the Consulting Services Agreement. Because Top Favour, Hongyuan and Hongli are under common control, the above contractual arrangements have been accounted for as a reorganization of entities and the consolidation of the Top Favour, Hongyuan and Hongli has been accounted for at the historical cost and prepared on the basis as if the contractual arrangements had become effective as of the beginning of the first period presented in the accompanying consolidated financial statements. Use of estimates The preparation of the unaudited consolidated financial statements in conformity with U.S. 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 unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to materials that may contain coal that are the basis for future cash flow estimates and units-of-production depletion calculations; asset impairments; allowance for doubtful accounts and loans receivable; valuation allowances for deferred income taxes; reserves for contingencies; stock-based compensation and the fair value and accounting treatment for warrants. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results may differ significantly from these estimates. Stock-based compensation The Company records share-based compensation expense based upon the grant date fair value of share-based awards. The value of the award is principally recognized as expense ratably over the requisite service periods. The Company uses the Black-Scholes Merton (“BSM”) option-pricing model, which incorporates various assumptions including volatility, expected life and interest rates to determine fair value. The Company’s expected volatility assumption is based on the historical volatility of Company’s stock. The expected life assumption is primarily based on the simplified method of the terms of the options. 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. Stock-based compensation expense is recognized based on awards expected to vest. U.S. GAAP require forfeitures to be estimated at the time of grant and revised in subsequent periods, if necessary, when actual forfeitures differ from those estimates. There were no estimated forfeitures as the Company has a short history of issuing options. Revenue recognition Coal and coke sales are recognized at the date of shipment to customers when a formal arrangement exists, the price is fixed or determinable, the delivery is completed, no other significant obligations of the Company exist and collectability is reasonably assured. This generally occurs when coal and coke is loaded onto trains or trucks at one of the Company’s loading facilities or at third party facilities. Substantially, if not all, of the electricity generated by Hongguang Power is typically used internally by Baofeng Coking. Supply of surplus electricity generated by Hongguang Power to the national power grid is mandated by the local utilities board. The value of the surplus electricity supplied, if it exists, is calculated based on actual kilowatt-hours produced and transmitted and at a fixed rate determined under contract. During the three months ended September 30, 2015 and 2014, the Company did not generate any electricity power because Hongguang Power has been temporarily closed since July 2014. The Company generally sells syngas under long-term agreements at fixed vending prices. In some cases, syngas may be sold with periodic price adjustments. Revenues are recognized when the products are delivered, which occurs when the customer has taken title and has assumed the risks and rewards of ownership, prices are fixed or determinable and collectability is reasonably assured. Coal, coke and syngas sales represent the invoiced value of goods, net of a value-added tax (“VAT”), sales discounts and actual returns at the time when product is sold to the customer. Foreign currency translation and other comprehensive income The reporting currency of the Company is the U.S. dollar. The functional currency of the Company, its subsidiaries and VIEs in the PRC is denominated in RMB. For the subsidiaries and VIEs whose functional currencies are other than the U.S. dollar, all assets and liabilities accounts were translated at the exchange rate on the balance sheet date; shareholders’ equity is translated at the historical rates and items in the statement of operations are translated at the average rate for the period. Items in the cash flow statement are also translated at average translation rates for the periods, therefore, amounts reported on the statement of cash flows will not necessarily agree with changes in the corresponding balances on the balance sheet. Translation adjustments resulting from this process are included in accumulated other comprehensive income in the statement of equity. The resulting transaction gains and 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. The balance sheet amounts, with the exception of equity, at September 30 and June 30, 2015 were translated at RMB 6.35 to $1 and RMB 6.11 to $1, respectively. The average translation rates applied to income and cash flow statement amounts were at RMB 6.25 to $1 and RMB 6.16 to $1 for the three months ended September 30, 2015 and 2014, respectively. Fair value of financial instruments The Company uses a three-level valuation hierarchy for disclosures of fair value measurement. The carrying amounts reported in the accompanying consolidated balance sheets for receivables, payables and short term loans qualify as financial instruments are a reasonable estimate of fair value because of the short period of time between the origination of such instruments, their expected realization and, if applicable, the stated rate of interest is equivalent to rates currently available. The three levels of valuation hierarchy 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 assets or liability, either directly or indirectly, for substantially the full term of the financial instruments. Level 3 Inputs to the valuation methodology are unobservable. The Company determined that the carrying value of its long-term loans approximated their fair value using level 2 inputs by comparing the stated loan interest rate to the rate charged by the Bairui Trust on similar loans (see Note 13). The following table sets forth by level within the fair value hierarchy the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2015: Carrying value at Fair value measurement at Level 1 Level 2 Level 3 Warrants liability $ 380,237 $ - $ 380,237 $ - The following is a reconciliation of the beginning and ending balances of warrants liability measured at fair value on a recurring basis using observable inputs as of September 30 and June 30, 2015: September 30, June 30, 2015 2015 Beginning fair value $ 2,915,649 $ 16 Realized gain recorded in earnings (2,515,412 ) (7,131,724 ) Granted financial instrument - 10,047,357 Ending fair value $ 380,237 $ 2,915,649 September 30, June 30, Number of shares exercisable 1,671,664 1,721,664 Range of exercise price $ 6.08-48.00 $ 6.08-48.00 Stock price $ 0.44 $ 1.75 Expected term (years) 1.53-3.82 0.00-4.07 Risk-free interest rate 0. 49-1.10 0.02-1.34 % Expected volatility 86 -121 % 51-88 % In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Company is required to record certain financial assets and liabilities at fair value on a non-recurring basis. Generally, assets are recorded at fair value on a non-recurring basis as a result of impairment charges. For the three months ended September 30, 2015 and 2014, the Company’s two long term investments were not considered impaired. The Company did not identify any other assets and liabilities that are required to be presented on the consolidated balance sheets at fair value. Cash The Company considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents for cash flow statement purposes. Cash includes cash on hand and demand deposits in accounts maintained with state owned banks within the PRC and with banks in Hong Kong and in the United States. Balances at financial institutions or state owned banks within the PRC are not covered by insurance. Balances at financial institutions in Hong Kong may, from time to time, exceed Hong Kong Deposit Protection Board’s insured limits. As of September 30 and June 30, 2015, the Company had $63,203 and $37,911 of cash deposits, which were not covered by insurance, respectively. The Company has not experienced any losses in such accounts. Accounts receivable, net During the normal course of business, the Company extends unsecured credit not exceeding three months to its customers. Management regularly reviews aging of receivables and changes in payment trends by its customers, and records an allowance when management believes collection of amounts due are at risk. Accounts receivables are considered past due after three months from the date credit was granted. Accounts considered uncollectible after exhaustive efforts to collect are written off. The Company regularly reviews the credit worthiness of its customers and, based on the results of the credit review, determines whether extended payment terms can be granted to or, in some cases, partial prepayment is required from certain customers. As of September 30 and June 30, 2015, $626,073 and $217,905 allowance for doubtful accounts was provided, respectively. Other receivables and deposit Other receivables include security deposit made for auction of purchasing non-performing assets, advances to employees for general business purposes and other short term non-traded receivables from unrelated parties, primarily as unsecured demand loans, with no stated interest rate or due date. Management regularly reviews aging of receivables and changes in payment trends and records a reserve when management believes collection of amounts due are at risk. Accounts considered uncollectible are written off after exhaustive efforts at collection. There was no allowance for doubtful accounts provided as of September 30, 2015 or June 30, 2015, respectively Inventories Inventories are stated at the lower of cost or market, using the weighted average cost method. Inventories consist of raw materials, supplies, work in process, and finished goods. Raw materials mainly consist of coal (mined and purchased), rail, steel, wood and additives used by the Company. The cost of finished goods includes (1) direct costs of raw materials, (2) direct labor, (3) indirect production costs, such as allocable utilities cost, and (4) indirect labor related to the production activities, such as assembling and packaging. 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. On an ongoing basis, inventories are reviewed for potential write-down for estimated obsolescence or unmarketable inventories equal to the difference between the costs of inventories and the estimated net realizable value based upon forecasts for future demand and market conditions. When inventories are written-down to the lower of cost or market, they are not marked up subsequently based on changes in underlying facts and circumstances. As of September 30 and June 30, 2015, amount to $42,877 and $44,597 was reported as allowance for impairment. Advances to suppliers The Company advances monies or may legally assign its notes receivable-trade (which are guaranteed by banks) to certain suppliers for raw material purchases. Such advances are interest-free and unsecured. Management regularly reviews aging of advances to suppliers and changes in materials receiving trends and records an allowance when management believes collection of materials due are at risk. Advances aged over one year and considered uncollectible are written off after exhaustive efforts at collection. As of September 30 and June 30, 2015, $1,312,298 and $1,512,785 allowance for doubtful accounts was provided, respectively. Plant and equipment, net Plant and equipment are stated at cost. Expenditures for maintenance and repairs are charged to earnings as incurred, while additions, renewals and betterments that extend the useful life are capitalized. When items of plant and equipment are retired or otherwise disposed, the related cost and accumulated depreciation are removed from the respective accounts, and any gain or loss is included in operations. Mine development costs are capitalized and amortized by the units of production method over estimated total amount of mineralized coal materials. Depreciation of plant and equipment is provided using the straight-line method for substantially all assets with estimated lives as follows: Estimated useful life Building and plant 20 years Machinery and equipment 10-20 years Other equipment 1-5 years Transportation equipment 5-7 years Construction-in-progress (“CIP”) includes direct costs of constructions for coke gasification facility, UCG underground safety improvement, and the Company’s new coking plant. Interest incurred during the period of construction, if material, is capitalized. For the three months ended September 30, 2015 and 2014, no interests were capitalized into CIP for construction is halted during the period. All other interest is expensed as incurred. CIP is not depreciated until such time the asset in question is completed and put into service. Security deposit A deposit was made to Henan Coal Seam Gas and is related to its joint venture with Zhonghong (see Note 12). Management regularly reviews aging of the deposit and changes in payment trends and records a reserve when management believes collection of amounts due are at risk. Accounts considered uncollectible are written off after exhaustive efforts at collection. As of September 30 and June 30, 2015, $4,721,584 and $4,887,984 allowance for doubtful accounts was provided, respectively. Intangible assets Costs to obtain land use rights are recorded based on the fair value at acquisition and amortized over 36 to 40 years, the contractual period of the rights. Intangible assets with finite lives are amortized over their useful lives and reviewed at least annually for impairment. Mining rights are capitalized at fair value when acquired, including amounts associated with any value beyond the total amount of mineralized coal materials, and amortized to operations as depletion expense using the units-of-production method over the estimated amount of mineralized coal materials. The Company’s coal mines are controlled through its VIEs, which control generally lasts until the mineralized coal materials are depleted . Impairment of long - lived assets The Company evaluates long-lived tangible and intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable from its estimated future cash flows, in accordance with the accounting guidance regarding “Disposal of Long-Lived Assets.” Recoverability is measured by comparing an asset’s carrying value to the related projected undiscounted cash flows generated by the long-lived asset or asset group, considering a number of factors including past operating results, budgets, economic projections, market trends and product development cycles. When the carrying value of the asset exceeds the related undiscounted cash flows, the asset is considered impaired, and a second test is performed to measure the amount of impairment loss to the extent that the carrying value exceeds its fair value As of September 30 and June 30, 2015, $2,348,936 and $2,431,718 impairment reserve against long-lived assets. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third party independent appraisals, as considered necessary. Long-term investments Investments in equity securities of privately-held companies in which the Company holds less than 20% voting interest and to which the Company does not have the ability to exercise significant influence are accounted for under the cost method. Entities in which the Company has the ability to exercise significant influence, but does not have a controlling interest, are accounted for under the equity method. Significant influence is generally considered to exist when the Company has between 20% and 50% of ownership interest in the voting share, but other factors, such as representation on the board of directors, voting rights and the impact of commercial arrangements, are considered in determining whether the equity method of accounting is appropriate. The Company evaluates potential impairment whenever events or changes in circumstances indicate that the carrying amount of the investments may not be recoverable. For investments carried at cost, the Company recognizes impairment in the event that the carrying value of the investment exceeds the Company’s proportionate share of the net book value of the investee. Management believes that no impairment charge was necessary as of September 30 and June 30, 2015. Asset retirement cost and obligations The Company accounts for the asset retirement cost and obligations to retire tangible long-lived assets in accordance with U.S. GAAP, which requires that the Company’s legal obligations associated with the retirement of long-lived assets be recognized at fair value at the time the obligations are incurred. Such obligations are incurred when development commences for underground mines or construction begins for support facilities, refuse areas and slurry ponds. If an entity has a conditional asset retirement obligation, a liability should be recognized when the fair value of the obligations can be reasonably estimated. The obligation’s fair value is determined using discounted cash flow techniques and is accreted over time to its expected settlement value. Upon initial recognition of a liability, a corresponding amount is capitalized as part of the carrying amount of the related long-lived asset. Amortization of the related asset is calculated on a unit-of-production method by amortizing the total estimated cost over the salable materials that may contain coal as determined under SEC Industry Guide 7, multiplied by the production during the period. Asset retirement costs generally include the cost of reclamation (the process of bringing the land back to its natural state after completion of exploration activities) and environmental remediation (the physical activity of taking steps to remediate, or remedy, any environmental damage caused). In May 2009, the Henan Bureau of Finance and the Bureau of Land and Resource issued regulations requiring mining companies to file an evaluation report regarding the environmental impacts of their mining (the “Evaluation Report”) before December 31, 2010. The relevant authorities would then determine whether to approve the Evaluation Report after performing on-site investigation, and the asset retirement obligation would be determined by the authorities based on the approved filing. Such requirement was extended along with the extension of the provincial mine consolidation schedule, although the specific extension date has not been finalized by the relevant provincial authorities. The Company did not record any asset retirement obligation as of September 30 and June 30, 2015 because the Company did not have sufficient information to reasonably estimate the fair value of such obligation. The range of time over which the Company may settle the obligation is unknown and cannot be reasonably estimated. In addition, the settlement method for the obligation cannot be reasonably determined. The amount of the obligation to be determined by the relevant authorities is affected by several factors, such as the extent of remediation required in and around the mining area, the methods to be used to remediate the mining site, and any government grants which may or may not be credited to the mining companies. The Company will recognize the liability in the period in which sufficient information is available to reasonably estimate its fair value. Income taxes Deferred income taxes are provided on the asset and liability method for temporary differences arising from differences between the carrying amount of assets and liabilities in the financial statements and the corresponding tax basis used in the computation of assessable tax profit. In principle, deferred tax liabilities are recognized for all taxable temporary differences, and deferred tax assets are recognized to the extent that it is probably that taxable profit will be available against which deductible temporary differences can be utilized. Deferred tax is calculated at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled. Deferred tax is charged or credited in the income statement, except when it related to items credited or charged directly to equity, in which case the deferred tax is also dealt with in equity. An uncertain tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Penalties and interest incurred related to underpayment of income tax are classified as income tax expense in the period incurred. No significant penalties or interest relating to income taxes were incurred during the three months ended September 30, 2015 and the year ended June 30, 2015. Chinese income taxes The Company’s subsidiary and VIEs that operate in the PRC are governed by the national and local income tax laws of that country (the “Income Tax Laws”), and are generally subject to a statutory income tax rate of 25% of taxable income, which is based on the net income reported in the statutory financial statements after appropriate tax adjustment. Value added tax (“VAT”) Sales revenue represents the invoiced value of goods, net of VAT. All of the Company’s coal and coke are sold in the PRC and subject to a VAT at a rate of 17% of the gross sales price. This VAT may be offset by VAT paid by the Company on raw materials and other materials included in the cost of producing finished products. The Company records VAT payable and VAT receivable net of payments in its consolidated financial statements. The VAT tax return is filed to offset the payables against the receivables. Warrants liability A contract is designated as an asset or a liability and is carried at fair value on the Company’s balance sheet, with any changes in fair value recorded in its results of operations. The Company then determines which options, warrants and embedded features require liability accounting and records the fair value as a derivative liability. The changes in the values of these instruments are shown in the accompanying consolidated statements of income and other comprehensive income as “change in fair value of warrants.” In connection with the Company’s share exchange transaction in February 2010 with Top Favour, whereby Top Favour became a wholly-owned subsidiary of the Company (the “Share Exchange”), the Company adopted the provisions of an accounting standard regarding instruments that are indexed to an entity’s own stock. This accounting standard specifies that a contract that would otherwise meet the definition of a derivative but is both (a) indexed to the Company’s own stock and (b) classified in equity in the statement of financial position would not be considered a derivative financial instrument. It provides a new two-step model to be applied in determining whether a financial instrument or an embedded feature is indexed to an issuer’s own stock and thus able to qualify for the scope exception within the standards. As a result of adopting this accounting standard, all warrants issued after the Share Exchange are recorded as a liability because their strike price is denominated in U.S. dollars, while the Company’s functional currency is denominated in RMB. All warrants issued before the Share Exchange, which were treated as equity pursuant to the derivative treatment exemption prior to the Share Exchange, are also no longer afforded equity treatment for the same reason. Since such warrants are no longer considered indexed to the Company’s own stock, all future changes in their fair value will be recognized currently in earnings until they are exercised or expire. Noncontrolling interests As further discussed in Note 20, noncontrolling interests mainly consist of a 40% equity interest of Xingsheng Coal owned by unrelated parties. For the three months ended September 30, 2015 and 2014, there was no net income or loss attributable to such noncontrolling interests because Xingsheng Coal was not operational during such periods. Earnings (losses) per share The Company reports earnings per share in accordance with the provisions of ASC – 260 “Earnings per Share.” This standard requires presentation of basic and diluted earnings per share in conjunction with the disclosure of the methodology used in computing such earnings per share. Basic earnings per share excludes dilution and is computed by dividing income available to common stockholders 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 to issue common stock were exercised and converted into common stock. Dilution is computed by applying the treasury stock method. Under this method, option 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 are used to purchase common stock at the average market price during the period. Comprehensive income Accounting standard regarding comprehensive income establishes requirements for the reporting and display of comprehensive income, its components and accumulated balances in a full set of general purpose financial statements. This accounting standard defines comprehensive income to include all changes in equity except those resulting from investments by owners and distributions to owners. Among other disclosures, it also requires all items recognized under current accounting standards as components of comprehensive income to be reported in financial statement that is presented with the same prominence as other financial statements. The Company's only current component of comprehensive income is foreign currency translation adjustments. Reclassifications Certain reclassifications have been made to the prior periods’ financial statements to conform to the current year presentation. These reclassifications had no effect on previously reported results of operations or the sum of retained earnings and statutory reserves.
