SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements - In May 2014, the FASB issued ASU 2014-09, Revenues from Contracts with Customers. The new revenue guidance broadly replaces the revenue guidance provided throughout the Codification. The core principle of the revenue guidance is that an 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 or services. To achieve that core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The new revenue guidance also requires the capitalization of certain contract acquisition costs. Reporting entities must prepare new disclosures providing qualitative and quantitative information on the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. New disclosures also include qualitative and quantitative information on significant judgments, changes in judgments, and contract acquisition assets. At issuance, ASU 2014-09 was effective starting in 2017 for calendar-year public entities, and interim periods within that year. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which defers the adoption of ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. During the fourth quarter of 2016, The Cooperative completed the initial evaluation of the new standard and the related assessment and review of existing revenue contracts with its customers. The Cooperative determined, on a preliminary basis, that the timing, pattern and amount of revenue recognized during the year should remain substantially the same. The Cooperative anticipates utilizing the full retrospective transition method. The primary impact of the adoption on the Cooperative’s financial statements will be the additional required disclosures around revenue recognition in the notes to the financial statements.
Investments	Investments — The Cooperative’s investment securities are held to maturity and recorded at amortized cost. The Cooperative’s investment in ProGold is recorded at historical cost plus its pro-rata share of ProGold’s net income and additional paid-in capital less distributions received from ProGold. Unrealized gains or losses are recorded in accumulated other comprehensive income within members’ equity. Gains and losses are determined using the specific identification method.
Cash and Cash Equivalents	Cash and Cash Equivalents — The Cooperative considers all demand accounts to be cash equivalents and overnight sweep accounts. Cash equivalents do not include money market accounts maintained by the Cooperative’s investment managers. Cash equivalents do not include any investment with a stated maturity date, regardless of the term to maturity.
Income Taxes	Income Taxes – Beginning September 1, 2009, Golden Growers Cooperative is taxed as a limited liability company under Subchapter K of the Internal Revenue Code. As such, the Cooperative will generally not be subject to income taxes. Instead, net income will be reported by its members who will be responsible for any income taxes which may be due. Prior to September 1, 2009, Golden Growers Cooperative was an exempt cooperative for federal income tax purposes. As such, the cooperative was generally not subject to income taxes. Instead, net proceeds were allocated to the Cooperative's patrons who were responsible for any income taxes which may have been due. The Cooperative’s net financial basis in its assets and liabilities exceeded its tax basis by approximately $8 million and $11 million as of December 31, 2016 and 2015, respectively.
Property and Equipment	Property and Equipment — Property and equipment are stated at cost. Depreciation on assets placed in service is provided using the straight-line method over estimated useful lives ranging from 5 to 10 years.
Accounting Estimates	Accounting Estimates — The preparation of the financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of 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.
Revenue Recognition	Revenue Recognition —The Cooperative’s members are contractually obligated to annually deliver corn to the Cooperative by either Method A or Method B or a combination of both. Under Method A, a member is required to physically deliver corn to the cooperative and under Method B a member appoints the cooperative as its agent to arrange for the acquisition and delivery of corn on the member’s behalf. For an annual fee of $92,000 paid quarterly, the Cooperative contractually appoints Cargill as its agent to arrange for the delivery of the corn by its members who elect to deliver corn using Method A and to acquire corn on its behalf for its members who elect to deliver corn using Method B. The price per bushel paid to the member who elects to deliver corn using Method B is equal to the price per bushel paid by Cargill to acquire the corn as the Cooperative’s agent. Members who deliver corn under Method A are paid the market price or contracted price for their corn at the time of delivery. The Cooperative pays members who deliver corn under Method A an incentive payment of $.05 per bushel while members who elect Method B to deliver corn pay the Cooperative a $.02 per bushel agency fee for the cost of having the Cooperative deliver corn on their behalf. The board has the discretion to change the incentive fee and the agency fee based on the Cooperative’s corn delivery needs. The incentive fee and agency fee are a component of Corn Expense. With respect to all Method A corn that is delivered, Cargill pays the aggregate purchase price for corn purchased from the Cooperative’s members to the Cooperative and then, on the Cooperative’s behalf, makes individual payments for corn directly to its members. If a Method A member fails to fully satisfy the corn delivery requirement, Cargill purchases replacement corn for which the Cooperative reimburses Cargill the amount by which the underlying contracted corn price is less than the price of buying the replacement corn that was due on the delivery date. The Method A member who fails to deliver corn is then invoiced by the Cooperative for the price of the corn. Based on what is to be delivered by its members using Method A, Cargill then purchases the remainder of the corn to be delivered by the Cooperative on behalf of its Method B delivering members. Because Cargill purchases the corn on the Cooperative’s behalf of Method B delivering members, the purchase price for the corn that would be paid to the Cooperative’s members if they actually delivered the corn offsets against the payment to be made by the Cooperative to Cargill for the cost to purchase the corn, thus no payment is made from Cargill to the Cooperative for corn delivered using Method B. The Cooperative has determined Corn Expense for Method B deliveries based on the average quarterly cost per bushel paid by Cargill to the Cooperative’s members for Method A quarterly deliveries.
Concentrations	Concentrations - Several times during the year, the Cooperative maintained a cash balance in excess of the Federal Deposit Insurance Corporation (“FDIC”) limits. At December 31, 2016, the Cooperative’s cash balance exceeded the FDIC insurance limits by approximately $2.8 million.
Fair Value Measurements	Fair Value Measurements - The Cooperative has determined the fair value of certain assets and liabilities in accordance with the provisions of Accounting Standards Codification (“ASC”) 820-10, which provides a framework for measuring fair value under generally accepted accounting principles. ASC 820-10 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820-10 requires that valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820-10 also establishes a fair value hierarchy, which prioritizes the valuation inputs into three broad levels. Level 1 inputs consist of quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the related asset or liability. Level 3 inputs are unobservable inputs related to the asset or liability.
