Business and Liquidity

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Liquidity	Note 1 — Business and Liquidity (a) Organization and description of business Synthesis Energy Systems, Inc. (referred to herein as “we”, “us”, and “our”), together with its wholly-owned and majority-owned controlled subsidiaries, is a global clean energy company that owns proprietary technology, SES Gasification Technology (“SGT”), for the low-cost and environmentally responsible production of synthesis gas (referred to as “syngas”). Our focus has been on commercializing our technology both in China and globally through the regional business platforms we have created with partners in Australia, Australian Future Energy Pty Ltd (“AFE”), and in Poland, SES EnCoal Energy sp. z o.o (“SEE”). Over the past ten years, we have successfully deployed our technology into five industrial scale projects in China. We invested in two of those industrial projects and have licensed our technology into the remaining three. Today, four of these projects are operating and are successfully demonstrating our technology. Our first project, the smaller scale Synthesis Energy Systems (Zao Zhang) New Gas Company Ltd (“ZZ”) commercial demonstration plant, operated for several years and also successfully demonstrated our technology and was retired in 2015. Through 2018, our business model had been to create value from our technology in China, through TSEC, in Australia through AFE, in Poland through SEE and from licensing our technology globally into projects in regions such as Brazil and India. However, we have determined that we do not have adequate cash to continue the commercialization of SGT and is now undertaking steps to reduce our expenditures. In the current quarter, we have suspended our global SGT commercialization efforts and we have severed most of our SGT technology resources. We operate our business from our headquarters located in Houston, Texas and our office in Shanghai, China. (b) Liquidity, Management’s Plan and Going Concern As of March 31, 2019, we had $2.4 million in cash and cash equivalents and a negative $4.7 million in working capital. The negative working capital is primarily due to the reclassification of the Senior Secured Debentures (the “Debentures”) from a noncurrent to a current liability in connection with a technical default, see Note 5 – Senior Secured Debentures As of May 13, 2019, we had $1.8 million in cash and cash equivalents. Of the $1.8 million in cash and cash equivalents, $1.7 million resides in the United States or easily accessed foreign countries and approximately $0.1 million resides in China. In the quarter ended March 31, 2019, we undertook additional steps to reduce our overhead expenses through the termination of certain technology and administrative employees and other reductions associated with office expenses and professional fees. On February 8, 2019, DeLome Fair, President and Chief Executive Officer, and principal financial officer of the Company, notified the Company of her intention to resign as President and Chief Executive Officer, and as a director on the Board effective March 1, 2019. Robert Rigdon, Vice Chairman of the Board and the former Chief Executive Officer of the Company succeeded Ms. Fair as President and Chief Executive Officer and principal financial officer. Ms. Fair’s employment agreement with the Company as of February 2016 was also terminated effective as such date. On March 29, 2019, Clarksons Platou Securities, Inc. (“CPS”) was engaged by our Board of Directors to act as our financial advisor. CPS will advise us as it conducts a process to evaluate financing options and strategic alternatives such as but not limited to a strategic merger, a sale, a recapitalization and/or a financing consisting of equity and/or debt securities. We remain focused on maximizing shareholder value and protecting the interests of our debtholders. A definitive timetable for completion of the evaluation of financing and strategic alternatives has not been set and there can be no assurance that the process will result in any transaction being announced or completed in the future. As noted above, CPS has been engaged by our Board of Directors to act as our financial advisor to advise the Company as it conducts a process to evaluate financing options and strategic alternatives such as but not limited to a strategic merger, a sale, a recapitalization and/or a financing consisting of equity and/or debt securities. In addition, we are undertaking further expense reductions which we expect to be realized over the remainder of calendar year 2019 to improve our financial position and preserve our available cash to allow more time to complete the financing and strategic alternative options evaluation work. As part of our overall strategy, to the extent possible, we intend to (i) work with CPS to complete the evaluation of financing options and strategic alternatives for the Company; (ii) monitor support and facilitate our minority ownership interest in BFR in order to realize the financial value through dividend income or other means; (iii) work to recover cash and monetize our Yima Joint Venture and TSEC Joint Venture operations such as through a restructuring or divestiture; and (iv) taking any additional steps to utilize our existing cash reserves in the most financially productive means possible. We believe that with the strategies above, we can continue to operate for the next five months. Based on the uncertainty of our plans to improve our financial position, our historical negative operating cash flows, our continued limited cash inflows and the potential uncertainties regarding transferring our funds from China to the U.S., there is substantial doubt about the Company’s ability to continue as a going concern, as disclosed in our prior periodic reports. We currently plan to use our available cash for: (i) evaluating and implementing financing, divestitures and strategic restructuring options; (ii) paying the interest related to the Debentures; and (iii) working capital for general corporate and administrative expenses. We currently have very limited financial and human resources to fully implement our plans and due to employee resource reductions and we have suspended our SGT commercialization efforts. We can make no assurances that AFE and our other business operations including any potential return from BFR will provide us with sufficient and timely cash flows to continue our operations. As noted above, we are seeking to improve our financial position and we may choose to raise additional capital through alternatives such as equity and debt financing, divesting certain assets such as our interests in our Yima Joint Venture, our TSEC Joint Venture, and our technology, and/or restructuring the Company. We cannot provide any assurance that any of these alternatives will be available to us in the future on acceptable terms or at all. Any such alternative could be dilutive to our existing stockholders and debtholders. If we cannot raise required funds on acceptable terms, we may further substantially reduce our expenses and we may not be able to, among other things, (i) sustain our general and administrative expenses; (ii) fund certain obligations as they become due including license fees and other vendor payments; (iii) respond to unanticipated capital requirements; or (iv) repay our indebtedness. In addition, we may be forced to seek relief to avoid or end insolvency through other proceedings including bankruptcy.

Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 — Summary of Significant Accounting Policies (a) Reverse Stock Split On December 4, 2017, we enacted a 1 to 8 reverse stock split as approved by a special stockholder meeting in November 2017. All share and per share amounts in the condensed consolidated financial statements have been retroactively restated to reflect the reverse stock split. (b) Basis of presentation and principles of consolidation The condensed consolidated financial statements for the periods presented are unaudited. Operating results for the three and nine month period ending March 31, 2019 are not necessarily indicative of results to be expected for the fiscal year ending June 30, 2019. The condensed consolidated financial statements are in U.S. dollars. Non-controlling interests in consolidated subsidiaries in the consolidated balance sheets represents minority stockholders’ proportionate share of the equity, including any contractual relationships in such subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto reported in the Company’s Annual Report on Form 10-K for the year ended June 30, 2018. Significant accounting policies that are new or updated from those presented in the Company’s Annual Report on Form 10-K for the year ended June 30, 2018 are included below. The condensed consolidated financial statements have been prepared in accordance with the rules of the United States Securities and Exchange Commission (“SEC”) for interim financial statements and do not include all annual disclosures required by generally accepted accounting principles in the United States. The accompanying condensed consolidated interim financial statements have been prepared on the basis of a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. As such, conditions exist the may raise substantial doubt regarding the Company’s ability to continue as a going concern. These condensed consolidated interim financial statements do no give effect to any adjustment that would be necessary should the Company be unable to continue as a going concern and therefore need to realize its assets and liquidate its liabilities and commitments in other than the normal course of business and at amounts different from those in the accompanying condensed consolidated interim financial statements. In the opinion of management, all adjustments which are necessary for fair statements of results for interim periods have been included. Immaterial prior period corrections. ● The allocation of losses to the noncontrolling interests in our subsidiary Synthesis Energy Systems Investments, Inc. (“SESI”), should have excluded certain charges contractually agreed to with the noncontrolling interest shareholder. Accordingly, we made adjustments to increase the net loss attributable to SES stockholders by approximately $43,000 and $461,000 for the three and nine-month periods ending March 31, 2018 with corresponding adjustments to increase accumulated deficit and decrease noncontrolling interests as of March 31, 2018. ● We also adjusted the balances as of June 30, 2017 on the condensed consolidated statement of equity to increase the noncontrolling interest by approximately $0.5 million, to decrease the accumulated other comprehensive income for approximately $3.2 million which resulted in a decrease in the accumulated deficit for approximately $2.7 million related to the conversion of our Yima Joint Venture investment from the equity method to the cost method in 2013. ● We also adjusted the balances on the condensed consolidated balance sheets, statement of operations, comprehensive loss, cash flow and statement of equity related to reversing approximately $67,000 of revenue prematurely recognized in the quarter ending September 30, 2018, related to our Yima Joint Venture billings as the collection of the consideration was not considered probable and the billings have not yet been collected. (c) Accounting for Variable Interest Entities (“VIEs”) and Financial Statement Consolidation Criteria We have equity investments in various privately held entities. We account for these investments either under the equity method or cost method of accounting depending on our ownership interest and the level of our influence in each joint venture. Investments accounted for under the equity method are recorded based upon the amount of our investment and adjusted each period for our share of the investee’s income or loss. Cost method investments are recorded at cost less any impairments. All investments are reviewed for changes in circumstance or the occurrence of events that suggest an other-than-temporary event where our investment may not be recoverable. The joint ventures which we have entered into may be considered a variable interest entity, (“VIE”). We consolidate all VIEs where we are the primary beneficiary. This determination is made at the inception of our involvement with the VIE and is continuously re-assessed. We consider qualitative factors and form a conclusion that we, or another interest holder, has a controlling financial interest in the VIE and, if so, whether it is the primary beneficiary. To determine the primary beneficiary, we consider who has the power to direct activities of the VIE that most significantly impacts the VIE’s performance and has the obligation to absorb losses from or the right to receive benefits of the VIE that could be significant to the VIE. We do not consolidate VIEs where we are not the primary beneficiary. As noted above, we account for these unconsolidated VIEs using either the equity method if we have significant influence but not control, or the cost method and include our net investment on our consolidated balance sheet. Under the equity method, our equity interest in the net income or loss from our investments are recorded in non-operating income/expense on a net basis on our consolidated statements of operations. In the event of a change in ownership, any gain or loss resulting from an investee share issuance is recorded in earnings. Controlling interest is determined by majority ownership interest and the ability to unilaterally direct or cause the direction of management and policies of an entity after considering any third-party participatory rights. (d) Revenue Recognition We may receive upfront licensing fee payments when a license agreement is entered into. Typically, the majority of a license fee is due once project financing and equipment installation occur. We recognize license fees for the use of its gasification systems as revenue when the license fees become due and payable under the license agreement, subject to the deferral of the amount of the performance guarantee. Fees earned for engineering services, such as services that relate to integrating our technology to a customer’s project, are recognized using the percentage-of-completion method or as services are provided. We adopted Accounting Standards Codification No. 606, Revenue from Contracts with Customers (e) Use of estimates The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Management considers many factors in selecting appropriate operational and financial accounting policies and controls, and in developing the assumptions that are used in the preparation of these consolidated financial statements. Management must apply significant judgment in this process. Among the factors, but not fully inclusive of all factors that may be considered by management in these processes are: the range of accounting policies permitted by accounting principles generally accepted in the United States of America; management’s understanding of the Company’s business for both historical results and expected future results; the extent to which operational controls exist that provide high degrees of assurance that all desired information to assist in the estimation is available and reliable or whether there is greater uncertainty in the information that is available upon which to base the estimate; expectations of the future performance of the economy, both domestically, and globally, within various areas that serve the Company’s principal customers and suppliers of goods and services; expected rates of exchange, sensitivity and volatility associated with the assumptions used in developing estimates; and whether historical trends are expected to be representative of future trends. The estimation process often times may yield a range of potentially reasonable estimates of the ultimate future outcomes and management must select an amount that lies within that range of reasonable estimates based upon the risks associated with the variability that might be expected from the future outcome and the factors considered in developing the estimate. Management attempts to use its business and financial accounting judgment in selecting the most appropriate estimate, however, actual amounts could and will differ from those estimates. (f) Fair value measurements Accounting standards require that fair value measurements be classified and disclosed in one of the following categories: Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The Company’s financial assets and liabilities are classified based on the lowest level of input that is significant for the fair value measurement. The Company measures equity investments without readily determinable fair value on a non- recurring basis. The fair value of the Yima Joint Venture was determined as of June 30, 2018 through an impairment valuation. Since there were no triggering events during the nine-months ended March 31, 2019, the carrying value of the investment in the Yima Joint Venture remains the same.

Accounting Policies [Abstract]
Recently Issued Accounting Standards	Note 3 – Recently Issued Accounting Standards In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842). The guidance in this ASU supersedes the leasing guidance in Topic 840, Leases. Under the new guidance, lessees are required to recognize lease assets and lease liabilities on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases, which makes narrow scope improvements to the standard for specific issues. In July 2018, the FASB also issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which provides an optional transition method allowing the standard to be applied at the adoption date. The new standard is effective for fiscal years beginning after December 15, 2019. The Company is currently evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07, which expands the scope of Topic 718, “Compensation – Stock Compensation”, to include share-based payment transactions for acquiring goods and services from non-employees. An entity should apply the requirements of Topic 718 to non-employee awards except for specific guidance on inputs to an option pricing model and the attribution of cost. This amendment specifies that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. This amendment also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. We have elected to early adopt the ASU No. 2018-07 for the quarter ending December 31, 2018 and there was no material effect on our financial condition, results of operations, cash flows or financial disclosures.

Equity Method Investments and Joint Ventures [Abstract]
Current Projects	Note 4 – Current Projects Australian Future Energy Pty Ltd In 2014, we established AFE together with an Australian company, Ambre Investments PTY Limited (“Ambre”). AFE is an independently managed Australian business platform established for the purpose of building a large-scale, vertically integrated business in Australia based on developing, building and owning equity interests in financially attractive and environmentally responsible projects that produce low-cost syngas as a competitive alternative to expensive local natural gas and LNG. On May 10, 2017, we entered into a project technology license agreement with AFE in connection with a project being developed by AFE in Queensland, Australia. AFE intends to form a subsidiary project company and assign the project technology license agreement to that company which will assume all of the obligations of AFE thereunder. Pursuant to the project technology license agreement, we granted a non-exclusive license to use our technology at the project to manufacture syngas and to use our technology in the design of the facility. In consideration, the project technology license agreement calls for a license fee to be finalized based on the designed plant capacity and a separate fee of $2.0 million for the delivery of a process design package. The license agreement calls for license fees to be paid as project milestones are reached throughout the planning, construction and first five years of plant operations. The success and timing of the project being developed by AFE will affect if and/or when we will be able to receive all of the payments related to this technology license agreement. However, there can be no assurance that AFE will be successful in developing this or any other project or that we will be able to deliver the technology for the project. In August 2017, AFE completed the acquisition of a mine development lease related to the 266-million ton coal resource near Pentland, Queensland through AFE’s wholly owned subsidiary, Great Northern Energy Pty Ltd. (“GNE”). In July 2018, we entered into a loan agreement (the “Loan Agreement”) with AFE to provide short-term funding in order to enable AFE to continue to progress its project related initiatives for the betterment of AFE shareholders and the successful promotion of their projects in the amount of 350,000 Australian Dollars, approximately $260,000. The Loan Agreement had a term of three months, subject to certain events, and an interest rate of 6%. AFE repaid the outstanding principal amount under the Loan Agreement plus interest in August 2018. In September 2018, AFE’s Gladstone Energy and Ammonia Project (“GEAP”) was formally announced in Queensland Parliament by Minister for State Development, Manufacturing, Innovation and Planning, Mr. Cameron Dick and was declared by the Queensland Co-Ordinator General as a Co-Ordinated Project. On April 4, 2019, we entered into a Technology Purchase Option Agreement (the “Agreement”) with AFE. Under the terms of the Agreement, AFE has an exclusive option through July 31, 2019 to purchase 100% ownership of Synthesis Energy Systems Technology, LLC, our wholly-owned subsidiary which owns our interest in the SGT. In addition, ownership rights to SGT are carved out of the transaction and retained by us for China and we have a three-year option period post-closing to monetize SGT for India, Brazil, Poland and for the DRI technology market segment. AFE issued one million shares to the Company in connection with the execution of the Agreement. AFE would also pay (i) an additional $2.0 million in three equal installments, with the first installment paid at closing and the remainder over the subsequent twelve months, and (ii) $3.8 million on the earlier of the closing of a contruction financing by AFE or five years from closing. The closing of the transaction is subject to the negotiation of definitive agreements and other conditions specified in the Agreement. In addition to the payment schedule above, AFE issued an additional one million shares with the execution of the Agreement and would also pay an additional $100,000 with the first installment paid at closing as full and final settlement of outstanding invoices owing AFE to us at the date of this Agreement. For our ownership interest in AFE, we have been contributing cash and engineering support for AFE’s business development while Ambre contributed cash and services. Additional ownership in AFE has been granted to the AFE management team and staff individuals providing services to AFE. In August 2017 and March 2018, we elected to make additional contributions of $0.47 million and $0.16 million respectively to assist AFE with developing its business in Australia. We account for our investment in AFE under the equity method. Our ownership interest of approximately 36% makes us the second largest shareholder. We also maintain a seat on the board of directors which allows us to have significant influence on the operations and financial decisions, but not control, of the company. Our carrying value of our AFE investment as of both March 31, 2019 and June 30, 2018 was zero. The following summarizes condensed financial information of AFE for the three and nine months ended March 31, 2019 and 2018 and as of March 31, 2019 and June 30, 2018 (in thousands): Three Months Ended Nine Months Ended March 31, March 31, Income Statement data: 2019 2018 2019 2018 Net loss $ (254 ) $ (181 ) $ (245 ) $ (1,178 ) Balance sheet data: March 31, 2019 June 30, 2018 Total assets $ 1,000 $ 421 Total Equity 542 (158 ) Batchfire Resources Pty Ltd As a result of AFE’s early stage business development efforts associated with the Callide coal mine in Central Queensland, Australia, AFE created BFR. BFR was a spin-off company for which ownership interest was distributed to the existing shareholders of AFE and to the new BFR management team in December 2015. BFR is registered in Australia and was formed for the purpose of purchasing the Callide thermal coal mine from Anglo-American plc (“Anglo-American”). The Callide mine is one of the largest thermal coal mines in Australia and has been in operation for more than 20 years. In October 2016, BFR stated that it had received investment support for the acquisition from Singapore-based Lindenfels Pte, Ltd, a subsidiary of commodity traders Avra Commodities, and as a result the acquisition of the Callide thermal coal mine from Anglo-American was completed in October 2016. We account for our investment in BFR under the cost method. Our limited ownership interest in BFR was approximately 11% and we do not have significant influence over the operation or financial decisions made by the company. At the time of the spin-off, the carrying amount of our investment in AFE was reduced to zero through equity losses. As such, the value of the investment in BFR post spin-off was also zero. As of March 31, 2019, our ownership interest in BFR was approximately 11% and the carrying value of our investment in BFR as of both March 31, 2019 and June 30, 2018 was zero. Townsville Metals Infrastructure Pty Ltd In August 2018, AFE formed a separate unrelated company, Townsville Metals Infrastructure Pty Ltd (“TMI”) for the purpose of completing the development of the required infrastructure such as rail and port modifications related to the transport of mined products including coal from the Pentland resource to the Townsville port. Ownership in TMI was distributed proportionately to the shareholders of AFE. Our ownership in TMI is approximately 38% upon the formation of TMI through our ownership interest in AFE. We account for our investment in TMI under the equity method. Our ownership interest of approximately 38% makes us the second largest shareholder. We may appoint one board director for each 15% ownership interest we hold in TMI which allows us to have significant influence on the operations and financial decisions, but not control, of the company. Our carrying value of our TMI investment as of March 31, 2019 was zero. Cape River Resources Pty Ltd In October 2018, AFE formed a separate unrelated company, Cape River Resources Pty Ltd (“CRR”) for the purpose of developing the Pentland resource into an operating thermal coal mine. Ownership in CRR was distributed proportionately to the shareholders of AFE with additional shares issued to the management team. Our ownership in CRR is approximately 38% upon the formation of CRR through our ownership interest in AFE. GNE sold its 100% ownership interest in the Pentland Coal Mine to CRR. CRR is currently finalizing the preparation of its Initial Advice Statement of the Pentland Coal Mine project to the Queensland Government for the development of the project for an initial 6.0 million metric tons per annum (“mtpa”) run of mine (“ROM”) coal operation, with allowance for expansion of the project for up to 9.0 million mtpa ROM coal operation. In its first phase of operation, 4.5 million mtpa of coal is planned for export to Asian markets with the balance of 1.5 million mtpa for feedstock to a future proposed coal gasification project. It is anticipated by CRR, based on current planning, for the project to be operational in 2022. CRR has indicated that a drilling program is planned to commence in late 2019 to expand the size and overall quality and understanding of the Pentland resource. We account for our investment in CRR under the equity method. Our ownership interest of approximately 38% makes us the second largest shareholder. We may appoint one board director for each 15% ownership interest we hold in CRR which allows us to have significant influence on the operations and financial decisions, but not control, of the company. Our carrying value of our CRR investment as of March 31, 2019 was zero. SES EnCoal Energy sp. z o. o. In October 2017, we entered into agreements with Warsaw-based EnInvestments sp. z o.o. Under the terms of the agreements, we and EnInvestments are equal shareholders of SEE and SEE will exclusively market, develop, and commercialize projects in Poland which utilize our technology, services and proprietary equipment and we share with SEE a portion of the technology license payments, net of fees, we receive from Poland. The goal of SEE is to establish efficient clean energy projects that provide Polish industries superior economic benefits as compared to the use of expensive, imported natural gas and LNG, while providing energy independence through our technological capabilities to convert the wide range of Poland’s indigenous coals, coal waste, biomass and municipal waste to valuable syngas products. SEE has developed a pipeline of projects and together we are actively working with Polish customers and partners to complete necessary project feasibility, permitting, and SGT technology agreement steps required prior to starting construction on the projects. For our ownership interest in SEE, we have been contributing cash and assisting in the development of SEE. SEE was funded in January 2018 with a cash contribution of approximately $6,000 and additional funding in March 2018 of approximately $76,000. In August 2018 we made an additional cash contribution of approximately $11,000. We account for our investment in SEE under the equity method. Our ownership interest of 50% makes us an equal shareholder and we also maintain two of the four seats on the management board which allows us to have significant influence on the operations and financial decisions, but not control, of the company. Our carrying value of our investment in SEE as of March 31, 2019 and June 30, 2018 was approximately $23,000 and $36,000, respectively. Yima Joint Venture In August 2009, we entered into joint venture contracts and related agreements with Yima Coal Industry Group Company (“Yima”). We continue to own a 25% interest in the Yima Joint Venture and Yima owns a 75% interest. In December 2017 and January 2018, on-going development cooperation and discussions with the Yima Joint Venture management resulted in the joint venture agreeing to pay various costs incurred by us during the construction and commissioning period of the facility in the amount of approximately 16 million Chinese Renminbi yuan, (“RMB”), (approximately $2.3 million). As of June 30, 2018, we have received 6.15 million RMB (approximately $0.9 million) of payments from the Yima Joint Venture related to these costs. Additional payments may be forthcoming. Due to uncertainty, revenues will be recorded upon receipt of payment. Dispite our continuous collection efforts, we have not received any additional payments during the nine-months ending March 31, 2019. Since 2014, we have accounted for this joint venture under the cost method of accounting. Our conclusion to account for this joint venture under this methodology is based upon our historical lack of significant influence in the Yima Joint Venture. The lack of significant influence was determined based upon our interactions with the Yima Joint Venture related to our limited participation in operating and financial policymaking processes coupled with our limited ability to influence decisions which contribute to the financial success of the Yima Joint Venture. We continue to evaluate our level of influence over the Yima Joint Venture. We evaluated the conditions of the Yima Joint Venture to determine whether an other-than-temporary decrease in value had occurred as of June 30, 2018 and 2017. At June 30, 2018, management determined there was a triggering event related to the value of its investment in the Yima Joint Venture. Lower production levels in the fourth quarter reduced the annual production below expectations, which resulted in a net increase in the working capital deficit and the debt level of the joint venture. At June 30, 2017, management determined that there were triggering events related to the value of its investment and these were the lower than expected production levels and the increased debt levels as compared to the previous year, which indicated a continued cash flow concern for the joint venture. Management determined these events in both years were other-than-temporary in nature and therefore conducted an impairment analysis utilizing a discounted cash flow fair market valuation and a Black-Sholes Model-Fair Value of Optionality used in valuing companies with substantial amounts of debt where a discounted cash flow valuation may be inadequate for estimating fair value with the assistance of a third-party valuation expert. In these valuations, significant unobservable inputs were used to calculate the fair value of the investment (see Note 2 – (e) Use of Estimates As of March 31, 2019, the Yima Joint Venture’s third-party loans balance was approximately 46.9 million Chinese Renminbi yuan (“RMB”), approximately $7.0 million, with $5.0 million due in April 2019 and $2.0 million due in April 2020. Management determined that there was not an other-than-temporary triggering event during the quarter ended March 31, 2019. The carrying value of our Yima Joint Venture investment was approximately $5.0 million as of both March 31, 2019 and June 30, 2018. We continue to monitor the Yima Joint Venture and could record an additional impairment in the future if operating conditions deteriorate or if the cash flow situation worsens. Tianwo-SES Clean Energy Technologies Limited Joint Venture Contract In February 2014, SES Asia Technologies Limited, one of our wholly owned subsidiaries, entered into a Joint Venture Contract (the “JV Contract”) with Zhangjiagang Chemical Machinery Co., Ltd., which subsequently changed its legal name to Suzhou Thvow Technology Co. Ltd. (“STT”), to form Tianwo-SES Clean Energy Technologies Limited (the “TSEC Joint Venture”). The purpose of the TSEC Joint Venture is to establish our gasification technology as the leading gasification technology in the TSEC Joint Venture territory (which is China, Indonesia, the Philippines, Vietnam, Mongolia and Malaysia) by becoming a leading provider of proprietary equipment and engineering services for the technology. The scope of the TSEC Joint Venture is to market and license our gasification technology via project sublicenses; procurement and sale of proprietary equipment and services; coal testing; and engineering, procurement and research and development related to the technology. In August 2017, we entered into a restructuring agreement of the TSEC Joint Venture (“Restructuring Agreement”). The agreed change in share ownership, reduction in the registered capital of the joint venture, and the final transfer of shares with local government authorities was completed in December 2017. In this restructuring, an additional party was added to the JV Contract, upon receipt of final government approvals, The Innovative Coal Chemical Design Institute (“ICCDI”) has become a 25% owner of the TSEC Joint Venture, we have decreased our ownership to 25% and STT has decreased its ownership to 50%. ICCDI previously served as general contractor and engineered and constructed all three projects for the Aluminum Corporation of China. We received 11.15 million RMB (approximately $1.7 million) from ICCDI as a result of the restructuring. In conjunction with the joint venture restructuring, we also received 1.2 million RMB (approximately $180,000) related to outstanding invoices for services we had provided to the TSEC Joint Venture. TSEC Joint Venture financial data The following summarizes condensed financial information of TSEC Joint Venture for the three and nine months ended March 31, 2019 and 2018 and as of March 31, 2019 and June 30, 2018 (in thousands): Three Months Ended Nine Months Ended March 31, March 31, Income Statement data: 2019 2018 2019 2018 Revenue $ 32 $ — $ 32 $ 109 Operating loss (556 ) (244 ) (1,023 ) (1,485 ) Net loss (556 ) (244 ) (1,023 ) (1,485 ) Balance sheet data: March 31, 2019 June 30, 2018 Current assets $ 4,092 $ 5,151 Noncurrent assets 105 1,376 Current liabilities 4,056 4,011 Equity 141 2,516 The TSEC Joint Venture is accounted for under the equity method. Our initial capital contribution in the formation of the venture was the Technology Usage and Contribution Agreement (“TUCA”), which is an intangible asset. As such, we did not record a carrying value at the inception of the venture. The carrying value of our investment in the TSEC Joint Venture as of both March 31, 2019 and June 30, 2018 was zero. Under the equity method of accounting, losses in the venture are not recorded if the losses cause the carrying value to be negative and there is no requirement to contribute additional capital. As we are not required to contribute additional capital, we have not recognized losses in the venture, as this would cause the carrying value to be negative. Had we recognized our share of the losses related to the venture, we would have recognized losses of approximately $0.3 million and $0.4 million for the nine months ended March 31, 2019 and 2018 respectively, and approximately $3.7 million from inception to date. TUCA Pursuant to the TUCA, we have contributed to the TSEC Joint Venture certain exclusive rights to our gasification technology in the TSEC Joint Venture territory, including the right to: (i) grant site specific project sub-licenses to third parties; (ii) use our marks for proprietary equipment and services; (iii) engineer and/or design processes that utilize our technology or our other intellectual property; (iv) provide engineering and design services for joint venture projects and (v) take over the development of projects in the TSEC Joint Venture territory that have previously been developed by us and our affiliates. As a result of the Restructuring Agreement, ICCDI was added as a party to the TUCA, but all other material terms remained the same.

Debt Disclosure [Abstract]
Senior Secured Debentures	Note 5 — Senior Secured Debentures On October 24, 2017, we entered into a securities purchase agreement (the “Purchase Agreement”) with certain accredited investors (the “Purchasers”) for the purchase of $8.0 million in principal amount of Debentures. The Debentures have a term of 5 years with an interest rate of 11% that adjusts to 18% in the event the Company defaults on an interest payment. The Debentures require that dividends received from BFR are used to pay down the principal amounts of outstanding Debentures. Additionally, we issued warrants to purchase 1,000,000 shares of common stock at $4.00 per common share. The Purchase Agreement and the Debentures contain certain customary representations, warranties and covenants. There are no financial metric covenants related to the Debentures. The transaction was approved by a special committee of our board of directors due to the fact that certain board members were Purchasers. Interest on the outstanding balance of Debentures is payable quarterly and commenced on January 2, 2018. All unpaid principal and interests on the Debentures will be due on October 23, 2022. The net offering proceeds to us from the sale of the Debentures and warrants, after deducting the placement agent’s fee and associated costs and expenses, was approximately $7.4 million, not including the proceeds, if any, from the exercise of the warrants issued in this offering. As compensation for their services, we paid T.R. Winston & Company, LLC (the “Placement Agent”): (i) a cash fee of $0.56 million (representing an aggregate fee equal to 7% of the face amount of the Debentures); and (ii) a warrant to purchase 70,000 shares of common stock, 7% of the warrants issued to the Purchasers (the “Placement Agent Warrants”). We also reimbursed certain expenses of the Placement Agent. The fair market value of the warrants was approximately $137,000 at the time of issuance and recorded as debt issuance cost. A total of approximately $1.0 million debt issuance cost was recorded as a result and is being amortized to interest expense over the term of the Debentures by using effective interest method beginning in October 2017. The warrants and Placement Agent Warrants contain provisions providing for the adjustment of the purchase price and number of shares into which the securities are exercisable in certain events. Also, under certain events, we shall, at the holder’s option, purchase the warrants from the holder by paying the holder an amount in cash based on a Black Scholes Option Pricing Model for remaining unexercised warrants. Under U.S. GAAP, this potential cash transaction requires us to record the fair market value of the warrants as a liability as opposed to equity. Management used a Monte Carlo Simulation method to value the warrants with Anti-Dilution Protection with the assistance of a third-party valuation expert. To execute the model and value the warrants, certain assumptions were needed as noted below: Valuation Date: October 24, 2017 Warrant Expiration Date: October 31, 2022 Total Number of Warrants Issued: 1,000,000 Contracted Conversion Ratio: 1:1 Warrant Exercise Price (USD) 4.00 Next Capital Raise Date: October 31, 2018 Threshold exercise price post Capital raise: 2.51 Spot Price (USD): 3.28 Expected Life (Years): 5.0 Volatility: 66.0 % Volatility (Per-period Equivalent): 19.1 % Risk Free Interest Rate: 2.04 % Risk Free Rate (Per-period Equivalent): 0.17 % Nominal Value (USD Mn): 4.0 No of Shares on conversion (Mn): 8.0 The results of the valuation exercise valued the warrants issued at $1.9528 per share, or $2.0 million in total. The total proceeds received are first allocated to the fair value of all the derivative instruments, and the remaining proceeds are then allocated to the Debentures, resulting in the Debentures being recorded at a discount from the face value. The Company recorded $8.0 million as the face value of the Debentures and a total of $2.0 million as discount of Debentures and $0.1 million as debt issuance cost for warrants issued to investors and placement agent, which is be amortized to interest expense over the term of the Debenture which resulted in a charge to interest expense of $0.3 million for both the three months ended March 31, 2019 and 2018, and $1.0 million and $0.6 million for the nine month periods ended March 31, 2019 and 2018 respectively. The effective annual interest rate of the debentures is approximately 18% after considering this $2.0 million discount related to the Debentures. The Debentures are guaranteed by the U.S. subsidiaries of the Company, as well as the Company’s British Virgin Islands subsidiary, pursuant to a Subsidiary Guarantee, in favor of the holders of the Debentures by the subsidiary guarantors, party thereto, as well as any future subsidiaries which the Company forms or acquires. The Debentures are secured by a lien on substantially all of the assets of the Company and the subsidiary guarantors, other than their equity ownership interest in the Company’s foreign subsidiaries, pursuant to the terms of the Purchase Agreement among the Company, the subsidiary guarantors and the holders of the Debentures. On November 5, 2018, a default occurred related to the Purchase Agreement and the Debentures due to the Company failing to timely file its Annual Report on Form 10-K. If the default is not waived by the holders of the Debentures, the holders may have the option to accelerate the principal and interest outstanding and other mandatory charges on the Debentures. The default has not been waived at the time of filing this Quarterly Report on Form 10-Q and accordingly, we have continued to reclassify the Debenture liabilities from noncurrent liabilities to current liabilities.

Derivative Liabilities	Note 6 — Derivative Liabilities The warrants issued to the Debenture investors and the Placement Agent contain provisions providing for the adjustment of the purchase price and number of shares into which the securities are exercisable under certain events. Under certain events, the Company shall, at the holder’s option, purchase the warrants from the holder by paying the holder an amount in cash based on a Black Scholes Option Pricing Model for remaining unexercised warrants. ASC 815, which establishes accounting and reporting standards for derivative instruments including certain derivative instruments embedded in other financial instruments or contracts and requires recognition of all derivatives on the balance sheet at fair value. Management used a Monte Carlo Simulation method to value the warrants with Anti-Dilution Protection with the assistance of a third-party valuation expert to initially record the fair value of these derivatives. The third-party valuation expert also assisted management in valuing the derivatives as of the year ended June 30, 2018 and the quarters ended September 30, 2018, December 31, 2018 and March 31, 2019 with the changes in the fair value reported as non-operating income or expense. To execute the model and value the derivatives, certain assumptions were needed as noted below: Assumptions Year Ended June 30, 2018 Quarter Ended March 31, 2019 Warrant Issue Date: October 24, 2017 October 24, 2017 Valuation Date: June 30, 2018 March 31, 2019 Warrant Expiration Date: October 31, 2022 October 31, 2022 Total Number of Warrants Issued: 1,070,000 1,070,000 Warrant Exercise Price (USD): 4.00 4.00 Next Capital Raise Date: (1) June 30, 2019 September 30, 2019 Threshold Exercise Price Post Capital Raise: (2) 2.15 0.80 Spot Price (USD): 3.28 0.55 Expected Life (Years): 4.3 3.6 Volatility: 65.0 % 75.0 % Volatility (Per-period Equivalent): 18.8 % 21.7 % Risk Free Interest Rate: 2.71 % 2.21 % Risk Free Rate (Per-period Equivalent): 0.22 % 0.18 % Nominal Value (USD Mn): 4.3 4.3 No. of Shares on Conversion (Mn): 1.1 1.1 Contracted Conversion Ratio: 1:1 1:1 Fair Values (in thousands) Fair Value without Anti-Dilution Protection: $ 1,704 $ 76 Fair Value of Embedded Derivative: 260 175 Fair Value of the Warrants Issued: $ 1,964 $ 251 Gain/(Loss) on Fair Value Adjustments to Derivative Liabilities $ 126 $ 203 (1) Next Capital Raise Date was assumed to be within a year of the debt offering and each valuation date. This was assumed as the Company has registered some type of capital raise in each year for the past 3 years. The Company may not have executed the capital raise but did register. (2) Threshold Exercise Price Post Capital Raise is assumed to be the 52-week low closing price, not to be confused with the 52-week low of the stock price with a floor price of $0.80 referenced in the Common Stock Purchase Warrant. The change in the derivative liability was mostly due to the Company’s stock price movements. Other changes in assumptions are listed above, some change with the passage time, interest rate fluctuations and stock market volatility.

The negative working capital is primarily due to the reclassification of the Debentures from noncurrent liabilities to current liabilities in connection with the technical default discussed above in Note 5 – Senior Secured Debentures. As of May 13, 2019, we had $1.8 million in cash and cash equivalents. Of the $1.8 million in cash and cash equivalents, $1.7 million resides in the United States or easily accessed foreign countries and approximately $0.1 million resides in China. In the quarter ended March 31, 2019, we undertook additional steps to reduce our overhead expenses through the termination of certain technology and administrative employees and other reductions associated with office expenses and professional fees. As part of our overall strategy, to the extent possible, we intend to (i) support AFE and SEE in those endeavors to develop energy, chemicals and resource projects where we would own an earned or carried equity interest in the project; (ii) monitor support and facilitate our minority ownership in BFR in order to realize the financial value through dividend income or other means; (iii) work to recover cash and monetize our Yima Joint Venture and TSEC Joint Venture operations; and (iv) taking any additional steps to utilize our existing cash reserves in the most financially productive means possible. We are undertaking strategies to improve our financial position and preserve our available cash to allow more time to realize the value we believe is in our assets, such as BFR, the Pentland coal resource and AFE. These strategies include the evaluation of a full range of financing, restructuring and strategic alternative options which may help us more fully realize the value in those assets. In addition, we are undertaking further expense reductions which we expect to be realized over the remainder of calendar year 2019 and we are also undertaking the necessary steps to transfer funds currently in our Chinese bank accounts to our U.S. based bank account in order to improve our available working capital. We may also divest assets such as our Yima Joint Venture, our TSEC Joint Venture and our technology. We believe that with the strategies above, we can continue to operate for the next five months, assuming we can successfully transfer our funds currently in China to the U.S. Based on the uncertainty of our plans to improve our financial position, our historical negative operating cash flows , our continued limited cash inflows and the potential uncertainties regarding transferring our funds from China to the U.S., there is substantial doubt about the Company’s ability to continue as a going concern, as disclosed in our prior periodic reports. We currently plan to use our available cash for: (i) evaluation and implementing financing, divestitures and strategic restructuring options; (ii) paying the interest related to the Senior Secured Debentures; and (iii) working capital for general corporate and administrative expenses. We currently have very limited financial and human resources to fully implement our plans and due to employee resource reductions, we have limited technology delivery capabilities. We can make no assurances that AFE, SEE and our other business operations including any potential return from BFR will provide us with sufficient and timely cash flows to continue our operations. Pursuant to our joint venture contracts, we are committed to providing technology and related support to our partners. If we do not to perform or deliver on these obligations, our partners could pursue legal action against us and our business and operating results could be seriously harmed. We cannot assure you that we will satisfy the conditions required to maintain these relationships under existing agreements or that we can prevent the termination of these agreements. In addition, our efforts to monetize our gasification technology are dependent on our ability to successfully maintain and transfer our intellectual property. Should we be unable to satisfactorily do so, we may lose all or part of the value of our technology. As noted in Note 1, Business and Liquidity On February 5, 2019, we received a notification from the NASDAQ Stock Market (the “NASDAQ”) indicating that the minimum bid price of our common stock has been below $1.00 per share for 30 consecutive business days and as a result, we are not in compliance with the minimum bid price requirement for continued listing. The NASDAQ notice has no immediate effect on the listing or trading of our common stock. Under NASDAQ Listing Rule 5810(c)(3)(A), we have a grace period of 180 calendar days, or until August 5, 2019, in which to regain compliance with the minimum bid price rule. To regain compliance, the closing bid price of our common stock must meet or exceed $1.00 per share for a minimum of ten consecutive business days during this grace period. If we do not regain compliance before August 5, 2019, the NASDAQ stated that it will provide us with written notice that our securities are subject to delisting. At that time, we may appeal the NASDAQ’s determination to a NASDAQ Listing Qualifications Panel, which would stay any further delisting action by the NASDAQ pending the final decision by the panel. Alternatively, we may be eligible for an additional grace period if we meet the initial listing standards, with the exception of bid price, for the NASDAQ Capital Market, and we effect a reverse stock split. As part of the proxy statement for the Company’s Annual Meeting of Stockholders for the year ended June 30, 2018, the Company is seeking stockholder approval to authorize a reverse split with the Board’s discretion to regain compliance. We cannot provide any assurances that such approval will be received. On November 5, 2018, a default occurred related to the Purchase Agreement and the Debentures due to the Company failing to timely file its Annual Report on Form 10-K. If the default is not waived by the holders of the Debentures, the holders may have the option to accelerate the principal and interest outstanding and other mandatory charges on the Debentures. Our ability to make payments on and to refinance our indebtedness, including our Debentures, and to fund planned capital expenditures will depend on our ability to generate sufficient cash flow from operations in the future. To a certain extent, this is subject to general economic, financial, competitive, legislative and regulatory conditions and other factors that are beyond our control. We cannot assure you that our business will generate sufficient cash flow from operations in an amount sufficient to enable us to pay principal and interest on our indebtedness, including our Debentures, or to fund our other liquidity needs. If our cash flow and capital resources are insufficient to fund our debt obligations, we may be forced to sell assets, seek additional equity or debt capital or restructure our debt. We cannot assure you that any of these remedies could, if necessary, be affected on commercially reasonable terms, or at all. Our cash flow and capital resources may be insufficient for payment of interest on and principal of our debt in the future, including payments on our recently issued Debentures, and any such alternative measures may be unsuccessful or may not permit us to meet scheduled debt service obligations, which could cause us to default on our obligations and could impair our liquidity or could force us to seek relief to avoid or end insolvency through other proceedings. We may be subject to future impairment losses due to potential declines in the fair value of our assets. As noted in Note 4 – Current Projects Yima Joint Venture Should general economic, market or business conditions decline further, and continue to have a negative impact on our revenues or other aspects of our business, we may be required to record impairment charges in the future, which could materially and adversely affect financial condition and results of operation.

Earnings Per Share [Abstract]
Net Loss Per Share	Note 10 – Net Loss Per Share All share amounts and number of shares used in the calculation of earnings per share have been adjusted for the 1 for 8 reverse stock split which became effective on December 4, 2017. Historical net loss per share of common stock is computed using the weighted average number of shares of common stock outstanding. Basic loss per share excludes dilution and is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding for the period. Stock options, warrants and unvested restricted stock are the only potential dilutive share equivalents the Company had outstanding for the periods presented. For the nine months ended March 31, 2019 and 2018, options, restricted shares and warrants to purchase common stock totaling 3.0 million and 3.6 million shares, respectively, were excluded from the computation of diluted earnings per share as their effect would have been anti-dilutive as the Company incurred net losses during those periods.

Commitments and Contingencies	Note 11 — Commitments and Contingencies Litigation The Company is currently not a party to any legal proceedings. Contractual Obligations In October 2017, the Company extended its corporate office lease term for an additional 13 months ending January 31, 2019 with rental related payments of approximately $18,000 per month (monthly rent changes depending on actual utility usage each month). In November 2018, the Company entered into a new office lease agreement for 12 months ending December 31, 2019 with rental related payments of approximately $3,300 per month (monthly rent can change depending on additional services usage each month). The Debentures have a term of 5 years and will mature in October 2022. Governmental and Environmental Regulation The Company’s operations are subject to stringent federal, state and local laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. Numerous governmental agencies, such as the U.S. Environmental Protection Agency, and various Chinese authorities, issue regulations to implement and enforce such laws, which often require difficult and costly compliance measures that carry substantial administrative, civil and criminal penalties or may result in injunctive relief for failure to comply. These laws and regulations may require the acquisition of a permit before operations at a facility commence, restrict the types, quantities and concentrations of various substances that can be released into the environment in connection with such activities, limit or prohibit construction activities on certain lands lying within wilderness, wetlands, ecologically sensitive and other protected areas, and impose substantial liabilities for pollution resulting from our operations. The Company believes that it is in substantial compliance with current applicable environmental laws and regulations and it has not experienced any material adverse effect from non-compliance with these environmental requirements.

Subsequent Events [Abstract]
Subsequent Events	Note 13 — Subsequent Events On April 4, 2019, we entered into a Techonology Purchase Option Agreement (the “Agreement”) with AFE. Under the terms of the Agreement, AFE has an exclusive option through July 31, 2019 to purchase 100% ownership of Synthesis Engergy Systems Technology, LLC, a wholly-owned subsidiary which owns our interest in the SGT. In addition, ownership rights to SGT are carved out of the transaction and retained by us for China and we have a three-year option period post-closing to monetize SGT for India, Brazil and Poland, and for the DRI technology market segment. AFE issued one million shares to us in connection with the execution of the Agreement. AFE would also pay (i) an additional $2.0 million in three equal installments, with the first installment paid at closing and the remainder over the subsequent twelve months, and (ii) $3.8 million on the earlier of the closing of a construction financing by AFE or five years from closing. The closing of the transaction is subject to the negotiation of definitive agreements and other conditions specified in the Agreement. In addition to the payment schedule above, AFE issued an additional one million shares with the execution of the Agreement and would also pay an additional $100,000 with the first instament paid at closing as full and final settlement of outstanding invoices owed by AFE to us at the date of this Agreement. On April 29, 2019, BFR issued additional shares as part of a rights offering. We did not execute our rights in this offering and therefore after the completion of the offering process and the issuance of the additional shares, our ownership interest has been diluted from approximately 11% to approximately 7%.

Accounting Policies [Abstract]
Reverse Stock Split	(a) Reverse Stock Split On December 4, 2017, we enacted a 1 to 8 reverse stock split as approved by a special stockholder meeting in November 2017. All share and per share amounts in the condensed consolidated financial statements have been retroactively restated to reflect the reverse stock split.
Basis of Presentation and Principles of Consolidation	(b) Basis of presentation and principles of consolidation The condensed consolidated financial statements for the periods presented are unaudited. Operating results for the three and nine month period ending March 31, 2019 are not necessarily indicative of results to be expected for the fiscal year ending June 30, 2019. The condensed consolidated financial statements are in U.S. dollars. Non-controlling interests in consolidated subsidiaries in the consolidated balance sheets represents minority stockholders’ proportionate share of the equity, including any contractual relationships in such subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto reported in the Company’s Annual Report on Form 10-K for the year ended June 30, 2018. Significant accounting policies that are new or updated from those presented in the Company’s Annual Report on Form 10-K for the year ended June 30, 2018 are included below. The condensed consolidated financial statements have been prepared in accordance with the rules of the United States Securities and Exchange Commission (“SEC”) for interim financial statements and do not include all annual disclosures required by generally accepted accounting principles in the United States. The accompanying condensed consolidated interim financial statements have been prepared on the basis of a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. As such, conditions exist the may raise substantial doubt regarding the Company’s ability to continue as a going concern. These condensed consolidated interim financial statements do no give effect to any adjustment that would be necessary should the Company be unable to continue as a going concern and therefore need to realize its assets and liquidate its liabilities and commitments in other than the normal course of business and at amounts different from those in the accompanying condensed consolidated interim financial statements. In the opinion of management, all adjustments which are necessary for fair statements of results for interim periods have been included. Immaterial prior period corrections. ● The allocation of losses to the noncontrolling interests in our subsidiary Synthesis Energy Systems Investments, Inc. (“SESI”), should have excluded certain charges contractually agreed to with the noncontrolling interest shareholder. Accordingly, we made adjustments to increase the net loss attributable to SES stockholders by approximately $43,000 and $461,000 for the three and nine-month periods ending March 31, 2018 with corresponding adjustments to increase accumulated deficit and decrease noncontrolling interests as of March 31, 2018. ● We also adjusted the balances as of June 30, 2017 on the condensed consolidated statement of equity to increase the noncontrolling interest by approximately $0.5 million, to decrease the accumulated other comprehensive income for approximately $3.2 million which resulted in a decrease in the accumulated deficit for approximately $2.7 million related to the conversion of our Yima Joint Venture investment from the equity method to the cost method in 2013. ● We also adjusted the balances on the condensed consolidated balance sheets, statement of operations, comprehensive loss, cash flow and statement of equity related to reversing approximately $67,000 of revenue prematurely recognized in the quarter ending September 30, 2018, related to our Yima Joint Venture billings as the collection of the consideration was not considered probable and the billings have not yet been collected.
Accounting for Variable Interest Entities ("VIEs") and Financial Statement Consolidation Criteria	(c) Accounting for Variable Interest Entities (“VIEs”) and Financial Statement Consolidation Criteria We have equity investments in various privately held entities. We account for these investments either under the equity method or cost method of accounting depending on our ownership interest and the level of our influence in each joint venture. Investments accounted for under the equity method are recorded based upon the amount of our investment and adjusted each period for our share of the investee’s income or loss. Cost method investments are recorded at cost less any impairments. All investments are reviewed for changes in circumstance or the occurrence of events that suggest an other-than-temporary event where our investment may not be recoverable. The joint ventures which we have entered into may be considered a variable interest entity, (“VIE”). We consolidate all VIEs where we are the primary beneficiary. This determination is made at the inception of our involvement with the VIE and is continuously re-assessed. We consider qualitative factors and form a conclusion that we, or another interest holder, has a controlling financial interest in the VIE and, if so, whether it is the primary beneficiary. To determine the primary beneficiary, we consider who has the power to direct activities of the VIE that most significantly impacts the VIE’s performance and has the obligation to absorb losses from or the right to receive benefits of the VIE that could be significant to the VIE. We do not consolidate VIEs where we are not the primary beneficiary. As noted above, we account for these unconsolidated VIEs using either the equity method if we have significant influence but not control, or the cost method and include our net investment on our consolidated balance sheet. Under the equity method, our equity interest in the net income or loss from our investments are recorded in non-operating income/expense on a net basis on our consolidated statements of operations. In the event of a change in ownership, any gain or loss resulting from an investee share issuance is recorded in earnings. Controlling interest is determined by majority ownership interest and the ability to unilaterally direct or cause the direction of management and policies of an entity after considering any third-party participatory rights.
Revenue Recognition	(d) Revenue Recognition We may receive upfront licensing fee payments when a license agreement is entered into. Typically, the majority of a license fee is due once project financing and equipment installation occur. We recognize license fees for the use of its gasification systems as revenue when the license fees become due and payable under the license agreement, subject to the deferral of the amount of the performance guarantee. Fees earned for engineering services, such as services that relate to integrating our technology to a customer’s project, are recognized using the percentage-of-completion method or as services are provided. We adopted Accounting Standards Codification No. 606, Revenue from Contracts with Customers
Use of estimates	(e) Use of estimates The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Management considers many factors in selecting appropriate operational and financial accounting policies and controls, and in developing the assumptions that are used in the preparation of these consolidated financial statements. Management must apply significant judgment in this process. Among the factors, but not fully inclusive of all factors that may be considered by management in these processes are: the range of accounting policies permitted by accounting principles generally accepted in the United States of America; management’s understanding of the Company’s business for both historical results and expected future results; the extent to which operational controls exist that provide high degrees of assurance that all desired information to assist in the estimation is available and reliable or whether there is greater uncertainty in the information that is available upon which to base the estimate; expectations of the future performance of the economy, both domestically, and globally, within various areas that serve the Company’s principal customers and suppliers of goods and services; expected rates of exchange, sensitivity and volatility associated with the assumptions used in developing estimates; and whether historical trends are expected to be representative of future trends. The estimation process often times may yield a range of potentially reasonable estimates of the ultimate future outcomes and management must select an amount that lies within that range of reasonable estimates based upon the risks associated with the variability that might be expected from the future outcome and the factors considered in developing the estimate. Management attempts to use its business and financial accounting judgment in selecting the most appropriate estimate, however, actual amounts could and will differ from those estimates.
Fair value measurements	(f) Fair value measurements Accounting standards require that fair value measurements be classified and disclosed in one of the following categories: Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The Company’s financial assets and liabilities are classified based on the lowest level of input that is significant for the fair value measurement. The Company measures equity investments without readily determinable fair value on a non- recurring basis. The fair value of the Yima Joint Venture was determined as of June 30, 2018 through an impairment valuation. Since there were no triggering events during the nine-months ended March 31, 2019, the carrying value of the investment in the Yima Joint Venture remains the same. The following table summarizes the assets of the Company measured at fair value as of March 31, 2019 and June 30, 2018 (in thousands): March 31, 2019 Level 1 Level 2 Level 3 Total Assets: Certificates of Deposit $ — $ 50 (1) $ — $ 50 Money Market Funds 454 (2) — — 454 Liabilities: Derivative Liabilities $ — $ — $ 251 $ 251 June 30, 2018 Level 1 Level 2 Level 3 Total Assets: Certificates of Deposit $ — $ 50 (1) $ — $ 50 Money Market Funds 4,345 (2) — — 4,345 Non-recurring Investment in Yima Joint Venture — — 5,000 5,000 Liabilities: Derivative Liabilities $ — $ — $ 1,964 $ 1,964 (1) Amount included in current assets on the Company’s consolidated balance sheets.

The carrying value of other financial instruments, including accounts receivable and accounts payable, approximate their fair values due to the short maturities on those instruments. Our Debentures are recorded at face value of $8.0 million and fair value is unable to be determined. The derivative liabilities are measured at fair value using a Monte Carlo simulation valuation methodology. See also Note 6 – Derivative Liabilities
