Summary of Business, Basis of Presentation and Liquidity	1. Summary of Business, Basis of Presentation and Liquidity Marrone Bio Innovations, Inc. (“Company”), formerly Marrone Organic Innovations, Inc., was incorporated under the laws of the State of Delaware on June 15, 2006, and is located in Davis, California. In July 2012, the Company formed a wholly-owned subsidiary, Marrone Michigan Manufacturing LLC (“MMM LLC”), which holds the assets of a manufacturing plant the Company purchased in July 2012. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation. The Company makes bio-based pest management and plant health products. The Company targets the major markets that use conventional chemical pesticides, including certain agricultural and water markets where its bio-based products are used as alternatives for, or mixed with, conventional chemical pesticides. The Company also targets new markets for which (i) there are no available conventional chemical pesticides or (ii) the use of conventional chemical pesticides may not be desirable or permissible either because of health and environmental concerns (including for organically certified crops) or because the development of pest resistance has reduced the efficacy of conventional chemical pesticides. The Company delivers EPA-approved and registered biopesticide products and other bio-based products that address the global demand for effective, safe and environmentally responsible products. The Company is an early stage company with a limited operating history and has a limited number of commercialized products. As of June 30, 2016, the Company had an accumulated deficit of $219,635,000, has incurred significant losses since inception and expects to continue to incur losses for the foreseeable future. The Company has funded operations primarily with net proceeds from public offerings of common stock, private placements of convertible preferred stock, convertible notes, and promissory notes and term loans, as well as with the proceeds from the sale of its products and payments under strategic collaboration and distribution agreements and government grants. The Company will need to generate significant revenue growth to achieve and maintain profitability. As of June 30, 2016, the Company had working capital of $24,056,000, including cash and cash equivalents of $21,159,000. As of June 30, 2016, the Company had debt and debt due to related parties of $21,647,000 and $36,086,000, respectively, for which the underlying debt agreements contain various financial and non-financial covenants, as well as certain material adverse change clauses. If the Company breaches any of the covenants contained within the debt agreements or if the material adverse change clauses are triggered, the entire unpaid principal and interest balances would be due and payable upon demand. In addition, as of June 30, 2016, the Company had a total of $3,004,000 of restricted cash relating to a debt agreement (see Note 6). The Company participates in a heavily regulated and highly competitive crop protection industry and believes that adverse changes in any of the following areas could have a material effect on the Company’s future financial position, results of operations or cash flows: inability to obtain regulatory approvals, increased competition in the pesticide market, market acceptance of the Company’s products, weather and other seasonal factors beyond the Company’s control, litigation or claims against the Company related to intellectual property, patents, products or governmental regulation, and the Company’s ability to support increased growth. Although the Company recognizes that it will likely need to raise additional funds in the future, there can be no assurance that such efforts will be successful or that, in the event that they are successful, the terms and conditions of such financing will not be unfavorable. Any future equity financing may result in dilution to existing shareholders and any debt financing may include additional restrictive covenants. Any failure to obtain additional financing or to achieve the revenue growth necessary to fund the Company with cash flows from operations will have a material adverse effect upon the Company and will likely result in a substantial reduction in the scope of the Company’s operations and impact the Company’s ability to achieve its planned business objectives. Without entering into a continuation of its current waiver due to expire December 31, 2016, entering into strategic agreements that include significant cash payments upfront, significantly increasing revenues from sales or raising additional capital through the issuance of equity, the Company expects it will exceed its maximum debt-to-worth requirement under a promissory note with Five Star Bank. Further, a violation of a covenant in one debt agreement will cause the Company to be in violation of certain covenants under each of its other debt agreements. Breach of covenants included in the Company’s debt agreements, which could result in the lenders demanding payment of the unpaid principal and interest balances, will have a material adverse effect upon the Company and would likely require the Company to seek to renegotiate these debt arrangements with the lenders. If such negotiations are unsuccessful, the Company may be required to seek protection from creditors through bankruptcy proceedings. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management is focused on efforts to increase liquidity in the near-term and plans to request an extension of the waiver on the debt-to-worth ratio. Such strategic collaborations and relief under the debt agreements may not be available or may be on terms that are not favorable to the Company. The Company’s inability to maintain compliance with its debt covenants could have a negative impact on the Company’s financial condition and ability to continue as a going concern. If the Company becomes unable to continue as a going concern, the Company may have to liquidate its assets, and might realize significantly less than the values at which they are carried on its financial statements, and stockholders may lose all or part of their investment in the Company’s common stock. The accompanying financial statements have been prepared under the assumption that the Company will continue to operate as a going concern, which contemplates the realization of assets and the settlement of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts of liabilities that may result from uncertainty related to the Company’s ability to continue as a going concern.
