Cash and cash equivalents Cash equivalents consist of highly liquid investments with original maturities of three may Accounts receivable, allowance for doubtful accounts , and credit risk Accounts receivable are recorded at the invoiced amount and do not bear interest. FutureFuel has established procedures to monitor credit risk and has not experienced significant credit losses in prior years. Accounts receivable have been reduced by an allowance for amounts that may Customer concentrations Significant portions of FutureFuel ’s sales are made to a relatively small number of customers.

FutureFuel records all derivative instruments at fair value. Fair value is determined by using the closing prices of the derivative instruments on the New York Mercantile Exchange at the end of an accounting period. Changes in fair value of the derivative instruments are recorded in the statements of operations as a component of cost of goods sold. FutureFuel maintains a margin account with a broker to collateralize these derivative instruments. In order to manage commodity price risk caused by market fluctuations in biofuel prices, future purchases of feedstock used in our biodiesel production, physical feedstock, finished product inventories attributed to the process, and other petroleum products purchased or sold, we may 815 20 25, 2016 2015. Our immediate recognition of derivative instrument gains and losses can cause net income to be volatile from period to period due to the timing of the change in valu e of the derivative instruments relative to the sale of the physical commodity sold.

Maintenance and repairs are charged to earnings; replacements and betterments are capitalized. When FutureFuel retires or otherwise disposes of an asset, it removes the cost of such asset and related accumulated depreciation from the accounts. FutureFuel records any profit and loss on retirement or other disposition in earnings. Depreciation is provided using the straight-line method over the following estimated useful lives: Building & building equipment (years) 20 - 39 Machinery and equipment (years) 3 – 33 Transportation equipment (years) 5 – 33 Other (years) 5 – 33 Impairment of assets Long-lived tangible assets FutureFuel evaluates the carrying value of long-lived tangible assets when events or changes in circumstances indicate that the carrying value may Indefinite-lived intangible asset Intangible assets with indefinite lives are not amortized, but are reviewed for impairment at least annually or whenever events or circumstances indicate the carrying value of the asset may fourth Deferred revenue FutureFuel has signed contracts with c ustomers to construct plant and related assets on FutureFuel’s property for the manufacture of custom chemicals. The cost of construction has been funded by the customers with title and risk of loss to the equipment residing with FutureFuel. Reimbursements are recognized as deferred revenue and are amortized over the expected life of the customer relationship starting upon the completion of construction and the asset being placed into service. Additionally, FutureFuel has been awarded grants from governme ntal agencies related to the construction of production equipment and infrastructural improvements at its plant site. The cost of construction of these projects has been either funded by the governmental agencies directly or funded by FutureFuel who has then been reimbursed by the governmental agencies. Direct payments and reimbursements for construction costs have been recognized as deferred revenue and will be amortized into earnings over the expected life of the applicable customer relationship or the life of the asset if no direct customer relationship is tied to the asset. Such amortization will not begin until the asset has been placed into service and all contingencies associated with the grants are fulfilled. Asset retirement obligations FutureFuel establishes reserves for closure/post-closure costs associated with the environmental and other assets it maintains. Env ironmental assets include but are not limited to waste management units such as destructors, landfills, storage tanks, and boilers. When these types of assets are constructed or installed, a liability is established for the future costs anticipated to be associated with the closure of the site based on an expected life of the environmental assets, the applicable regulatory closure requirements, and FutureFuel’s environmental policies and practices. These expenses are charged into earnings over the estimated useful life of the assets. Currently, FutureFuel estimates the useful life of each individual asset up to 35 Environmental costs are capitalized if they extend the life of the related property, increase its capacity, and/or mitigate or prevent future contamination. The cost of operating and maintaining environmental control facilities is charged to expense. Income taxes Income taxes are accounted for using the asset and liability method. Under this method, income tax assets and liabilities are recognized for temporary differences between financial statement carrying amounts of assets and liabilities and their respective income tax basis. A future income tax asset or liability is estimated for each temporary difference using enacted and substantively enacted income tax rates and laws expected to be in effect when the asset is realized or the liability settled. A valuation allowance is established, if necessary, to reduce any future income tax asset to an amount that is more likely than not to be realized.

Revenue recognition For most product sales, revenue is recognized when product is shipped from our facilities and risk of loss and title have passed to the customer, which is in accordance with our customer contracts and the stated shipping terms. All custom manufactured products are manufactured under written contracts. Performance chemicals and biofuels are usually sold pursuant to the terms of written purchase orders. In general, customers do not have any rights of return, except for quality disputes. However, all of our products are tested for quality before shipment, and historically returns have been inconsequential. FutureFuel does not offer rebates or other warranties.

Co mprehensive income Comprehensive income is comprised of net income and other comprehensive income/(losses) (“ OCI”). Comprehensive income comprises all changes in stockholders’ equity from transactions and other events and circumstances from non-owner sources.

Commitments and contingent liabilities In the ordinary course of its business, FutureFuel enters into supply and sales contracts as deemed commercially desirable.

FutureFuel and its operations from time to time may investigations, and proceedings including product liability, personal injury, patent and intellectual property, commercial, contract, environmental, health and safety, and environmental matters, which are handled and defended in the ordinary course of business. FutureFuel accrues a liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, FutureFuel accrues the minimum amount. Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during a reporting period. Estimates are used when accounting for allowance for doubtful accounts, depreciation, amortization, asset retirement obligations, and income taxes as well as the evaluation of potential losses due to impairments or future liabilities. Actual results could differ materially from those estimates. Segment reporting FutureFuel identifies operating segments when separate financial information is available that is evaluated regularly b y its chief operating decision maker in assessing the performance of those segments and in determining how to allocate resources. FutureFuel has determined that it has two

Segment Reporting Disclosure [Text Block]	20) Segment information FutureFuel has two – chemicals and biofuels. The accounting policies of the segments are the same as those described in the summary of significant accounting policies in Note 2. Chemicals FutureFuel ’s chemicals segment manufactures diversified chemical products that are sold to third two Biofuels FutureFuel ’s biofuels business segment manufactures and markets biodiesel. Biodiesel revenues are generated through the sale of biodiesel to customers through FutureFuel’s distribution network at the Batesville Plant, through distribution facilities available at leased oil storage facilities, and through a network of remotely located tanks. Results of the biofuels business segment also reflect the sale of biodiesel blends with petrodiesel, petrodiesel with no biodiesel added, RINs, biodiesel production byproducts, and the purchase and sale of other petroleum products on common carrier pipelines. Summary of long-lived assets and revenues by geographic area All of FutureFuel ’s long-lived assets are located in the U.S. Most of FutureFuel ’s sales are transacted with title passing at the time of shipment from the Batesville Plant, although some sales are transacted based on title passing at the delivery point. While many of FutureFuel’s chemicals are utilized to manufacture products that are shipped, further processed, and/or consumed throughout the world, the chemical products, with limited exceptions, generally leave the United States only after ownership has transferred from FutureFuel to the customer. Rarely is FutureFuel the exporter of record, never is FutureFuel the importer of record into foreign countries, and FutureFuel is not always aware of the exact quantities of its products that are moved into foreign markets by its customers. FutureFuel does track the addresses of its customers for invoicing purposes and uses this address to determine whether a particular sale is within or without the United States.

Description of New Accounting Pronouncements Not yet Adopted [Text Block]	25) Recently issued accounting standards In May 2014, entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. To achieve the core principle, the guidance establishes the following five 1) 2) 3) 4) 5) December 15, 2016, July 2015, one May 2016, December 2016, In August 2016, Financial Accounting Standards Board (the “FASB”) issued guidance to reduce existing diversity in practice in regards to how cash receipts and cash payments are presented and classified in the statement of cash flows. The guidance specifically addresses the following items: debt prepayment or debt extinguishment costs; settlement of zero December 15, 2017, During June 2016, dit loss methodology and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. Purchased credit deteriorated loans will receive an allowance account for expected credit losses at the acquisition date that represents a component of the purchase price allocation. Credit losses relating to available for sale debt securities will be recorded through an allowance for expected credit losses, with such allowance limited to the amount by which fair value is below amortized cost. An allowance will be established for estimated credit losses on held to maturity securities. This guidance is effective for fiscal years beginning after December 15, 2019 In March 2016, ion as a part of the simplification initiative that covers related tax accounting, cash flow presentation, and forfeitures. The two December 15, 2016, In February 2016, requires organizations that lease assets to recognize assets and liabilities on the balance sheet related to the rights and obligations created by those leases, regardless of whether they are classified as finance or operating leases. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease primarily will depend on its classification as a finance or operating lease. The guidance also requires new disclosures in order to help users of financial statements better understand the amount, timing, and uncertainty of cash flows arising from leases. The new standard is effective for annual reporting periods beginning after December 15, 2018, In November 2015, under the simplification and productivity initiative for presentation of deferred income tax liabilities and assets. This guidance simplifies the presentation of deferred income taxes such that deferred tax liabilities and assets are to be classified as noncurrent in a classified balance sheet. The update does not amend the current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount. This guidance was effective for annual reporting periods beginning after December 15, 2016, fourth 2016 2015 $7,188 $7,188.

Property, Plant and Equipment, Policy [Policy Text Block]	Property, plant , and equipment Property, plant, and equipment is carried at cost. Maintenance and repairs are charged to earnings; replacements and betterments are capitalized. When FutureFuel retires or otherwise disposes of an asset, it removes the cost of such asset and related accumulated depreciation from the accounts. FutureFuel records any profit and loss on retirement or other disposition in earnings. Depreciation is provided using the straight-line method over the following estimated useful lives: Building & building equipment (years) 20 - 39 Machinery and equipment (years) 3 – 33 Transportation equipment (years) 5 – 33 Other (years) 5 – 33

Revenue Recognition, Deferred Revenue [Policy Text Block]	Deferred revenue FutureFuel has signed contracts with c ustomers to construct plant and related assets on FutureFuel’s property for the manufacture of custom chemicals. The cost of construction has been funded by the customers with title and risk of loss to the equipment residing with FutureFuel. Reimbursements are recognized as deferred revenue and are amortized over the expected life of the customer relationship starting upon the completion of construction and the asset being placed into service. Additionally, FutureFuel has been awarded grants from governme ntal agencies related to the construction of production equipment and infrastructural improvements at its plant site. The cost of construction of these projects has been either funded by the governmental agencies directly or funded by FutureFuel who has then been reimbursed by the governmental agencies. Direct payments and reimbursements for construction costs have been recognized as deferred revenue and will be amortized into earnings over the expected life of the applicable customer relationship or the life of the asset if no direct customer relationship is tied to the asset. Such amortization will not begin until the asset has been placed into service and all contingencies associated with the grants are fulfilled.
Asset Retirement Obligations, Policy [Policy Text Block]	Asset retirement obligations FutureFuel establishes reserves for closure/post-closure costs associated with the environmental and other assets it maintains. Env ironmental assets include but are not limited to waste management units such as destructors, landfills, storage tanks, and boilers. When these types of assets are constructed or installed, a liability is established for the future costs anticipated to be associated with the closure of the site based on an expected life of the environmental assets, the applicable regulatory closure requirements, and FutureFuel’s environmental policies and practices. These expenses are charged into earnings over the estimated useful life of the assets. Currently, FutureFuel estimates the useful life of each individual asset up to 35 Environmental costs are capitalized if they extend the life of the related property, increase its capacity, and/or mitigate or prevent future contamination. The cost of operating and maintaining environmental control facilities is charged to expense.
Income Tax, Policy [Policy Text Block]	Income taxes Income taxes are accounted for using the asset and liability method. Under this method, income tax assets and liabilities are recognized for temporary differences between financial statement carrying amounts of assets and liabilities and their respective income tax basis. A future income tax asset or liability is estimated for each temporary difference using enacted and substantively enacted income tax rates and laws expected to be in effect when the asset is realized or the liability settled. A valuation allowance is established, if necessary, to reduce any future income tax asset to an amount that is more likely than not to be realized.

When a single amount cannot be reasonably estimated but the cost can be estimated within a range, FutureFuel accrues the minimum amount.
Use of Estimates, Policy [Policy Text Block]	Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during a reporting period. Estimates are used when accounting for allowance for doubtful accounts, depreciation, amortization, asset retirement obligations, and income taxes as well as the evaluation of potential losses due to impairments or future liabilities. Actual results could differ materially from those estimates.
Segment Reporting, Policy [Policy Text Block]	Segment reporting FutureFuel identifies operating segments when separate financial information is available that is evaluated regularly b y its chief operating decision maker in assessing the performance of those segments and in determining how to allocate resources.
