SIGNIFICANT ACCOUNTING POLICIES Principles of consolidation: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Bion Integrated Projects Group, Inc. (“Projects Group”), Bion Technologies, Inc., BionSoil, Inc., Bion Services, PA1, PA2; 58.9% Cash and cash equivalents : The Company considers all highly liquid investments purchased with an original maturity of three Property and equipment: Property and equipment are stated at cost and are depreciated, when placed into service, using the straight-line method over the estimated useful lives of the related assets, generally three twenty no no may not Stock-based compensation: The Company follows the provisions of Accounting Standards Codification (“ASC”) 718, Derivative Financial Instruments: Pursuant to ASC Topic 815 815” may Warrants: The Company has issued warrants to purchase common shares of the Company. Warrants are valued using a fair value based method, whereby the fair value of the warrant is determined at the warrant issue date using a market-based option valuation model based on factors including an evaluation of the Company’s value as of the date of the issuance, consideration of the Company’s limited liquid resources and business prospects, the market price of the Company’s stock in its mostly inactive public market and the historical valuations and purchases of the Company’s warrants. When warrants are issued in combination with debt or equity securities, the warrants are valued and accounted for based on the relative fair value of the warrants in relation to the total value assigned to the debt or equity securities and warrants combined. Concentrations of credit risk: The Company's financial instruments that are exposed to concentrations of credit risk consist of cash. The Company's cash is in demand deposit accounts placed with federally insured financial institutions and selected brokerage accounts. Such deposit accounts at times may not Noncontrolling interests: In accordance with ASC 810, Fair value measurements: Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market. The Company uses a fair value hierarchy that has three Level 1 Level 2 1, not Level 3 Observable inputs are based on market data obtained from independent sources, while unobservable inputs are based on the Company’s market assumptions. Unobservable inputs require significant management judgment or estimation. In some cases, the inputs used to measure an asset or liability may The fair value of cash and accounts payable approximates their carrying amounts due to their short-term maturities. The fair value of the loan payable is indeterminable at this time due to the nature of the arrangement with a state agency and the fact that it is in default. The fair value of the redeemable preferred stock approximates its carrying value due to the dividends accrued on the preferred stock which are reflected as part of the redemption value. The fair value of the deferred compensation and convertible notes payable - affiliates are not Revenue Recognition: Revenues are generated from the sale of nutrient reduction credits. The Company recognizes revenue from the sale of nutrient credits when there is persuasive evidence that an arrangement exists, when title has passed, the price is fixed or determinable, and collection is reasonably assured. The Company expects that technology license fees will be generated from the licensing of Bion’s integrated system. The Company anticipates that it will charge its customers a non-refundable up-front technology license fee, which will be recognized over the estimated life of the customer relationship. In addition, any on-going technology license fees will be recognized as earned based upon the performance requirements of the agreement. Annual waste treatment fees will be recognized upon receipt. Revenues, if any, from the Company’s interest in Integrated Projects will be recognized when the entity in which the Integrated Project has been developed recognizes such revenue. Income taxes: The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their tax bases, as well as net operating losses. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets or liabilities of a change in tax rates is recognized in the period in which the tax change occurs. A valuation allowance is provided to reduce the deferred tax assets by 100%, not not The Company is no 2009. not 12 The Company's policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. As of June 30, 2018, no June 30, 2018 2017. Loss per share: Basic loss per share amounts are calculated using the weighted average number of shares of common stock outstanding during the period. Diluted loss per share assumes the conversion, exercise or issuance of all potential common stock instruments, such as options or warrants, unless the effect is to reduce the loss per share or increase the earnings per share. During the years ended June 30, 2018 2017, The following table represents the warrants, options and convertible securities excluded from the calculation of basic loss per share: June 30, 2018 June 30, 2017 Warrants 12,245,452 8,588,729 Options 6,827,225 4,545,037 Convertible debt 7,549,082 9,115,428 Convertible preferred stock 17,000 16,000 The following is a reconciliation of the denominators of the basic and diluted loss per share computations for the years ended June 30, 2018 2017: Year ended June 30, 2018 Year ended June 30, 2017 Shares issued – beginning of period 24,748,213 23,573,057 Shares held by subsidiaries (Note 8) (704,309 ) (704,309 ) Shares outstanding – beginning of period 24,043,904 22,868,748 Weighted average shares for fully vested stock bonuses - 177,534 Weighted average shares issued during the period 395,155 413,649 Basic weighted average shares – end of period 24,439,059 23,459,931 Use of estimates: In preparing the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Recent Accounting Pronouncements: The Company continually assesses any new accounting pronouncements to determine their applicability. When it is determined that a new accounting pronouncement affects the Company’s financial reporting, the Company undertakes a study to determine the consequences of the change to its financial statements and assures that there are proper controls in place to ascertain that the Company’s financial statements properly reflect the change.
