Derivative Instruments and Hedging Activities Disclosure [Text Block] | Derivatives The Company’s operating results are affected by changes to commodity prices. The Trade and Ethanol businesses have established “unhedged” position limits (the amount of a commodity, either owned or contracted for, that does not have an offsetting derivative contract to lock in the price). To reduce the exposure to market price risk on commodities owned and forward purchase and sale contracts, the Company enters into exchange traded commodity futures and options contracts and over-the-counter forward and option contracts with various counterparties. These contracts are primarily traded via regulated commodity exchanges. The Company’s forward purchase and sales contracts are for physical delivery of the commodity in a future period. Contracts to purchase commodities from producers generally relate to the current or future crop years for delivery periods quoted by regulated commodity exchanges. Most contracts for the sale of commodities to processors or other commercial consumers generally do not extend beyond one year . Most of these contracts meet the definition of derivatives. While the Company considers its commodity contracts to be effective economic hedges, the Company does not designate or account for its commodity contracts as hedges as defined under current accounting standards. The Company primarily accounts for its commodity derivatives at estimated fair value. The estimated fair value of the commodity derivative contracts that require the receipt or posting of cash collateral is recorded on a net basis (offset against cash collateral posted or received, also known as margin deposits) within commodity derivative assets or liabilities. Management determines fair value based on exchange-quoted prices and in the case of its forward purchase and sale contracts, estimated fair value is adjusted for differences in local markets and non-performance risk. For contracts for which physical delivery occurs, balance sheet classification is based on estimated delivery date. For futures, options and over-the-counter contracts in which physical delivery is not expected to occur but, rather, the contract is expected to be net settled, the Company classifies these contracts as current or noncurrent assets or liabilities, as appropriate, based on the Company’s expectations as to when such contracts will be settled. Realized and unrealized gains and losses in the value of commodity contracts (whether due to changes in commodity prices, changes in performance or credit risk, or due to sale, maturity or extinguishment of the commodity contract) and grain inventories are included in cost of sales and merchandising revenues. Generally accepted accounting principles permit a party to a master netting arrangement to offset fair value amounts recognized for derivative instruments against the right to reclaim cash collateral or obligation to return cash collateral under the same master netting arrangement. The Company has master netting arrangements for its exchange traded futures and options contracts and certain over-the-counter contracts. When the Company enters into a future, option or an over-the-counter contract, an initial margin deposit may be required by the counterparty. The amount of the margin deposit varies by commodity. If the market price of a future, option or an over-the-counter contract moves in a direction that is adverse to the Company’s position, an additional margin deposit, called a maintenance margin, is required. The margin deposit assets and liabilities are included in short-term commodity derivative assets or liabilities, as appropriate, in the Condensed Consolidated Balance Sheets. The following table presents at March 31, 2020 , December 31, 2019 and March 31, 2019 , a summary of the estimated fair value of the Company’s commodity derivative instruments that require cash collateral and the associated cash posted/received as collateral. The net asset or liability positions of these derivatives (net of their cash collateral) are determined on a counterparty-by-counterparty basis and are included within current or noncurrent commodity derivative assets (or liabilities) on the Condensed Consolidated Balance Sheets: March 31, 2020 December 31, 2019 March 31, 2019 (in thousands) Net derivative asset position Net derivative liability position Net derivative asset position Net derivative liability position Net derivative asset position Net derivative liability position Cash collateral paid $ 22,855 $ — $ 56,005 $ — $ 21,751 $ — Fair value of derivatives 20,977 — (10,323 ) — 38,580 — Balance at end of period $ 43,832 $ — $ 45,682 $ — $ 60,331 $ — The following table presents, on a gross basis, current and noncurrent commodity derivative assets and liabilities: March 31, 2020 (in thousands) Commodity Derivative Assets - Current Commodity Derivative Assets - Noncurrent Commodity Derivative Liabilities - Current Commodity Derivative Liabilities - Noncurrent Total Commodity derivative assets $ 164,700 $ 3,240 $ 9,648 $ 142 $ 177,730 Commodity derivative liabilities (38,485 ) (119 ) (100,139 ) (2,667 ) (141,410 ) Cash collateral paid 22,855 — — — 22,855 Balance sheet line item totals $ 149,070 $ 3,121 $ (90,491 ) $ (2,525 ) $ 59,175 December 31, 2019 (in thousands) Commodity Derivative Assets - Current Commodity Derivative Assets - Noncurrent Commodity Derivative Liabilities - Current Commodity Derivative Liabilities - Noncurrent Total Commodity derivative assets $ 92,429 $ 1,045 $ 7,439 $ 18 $ 100,931 Commodity derivative liabilities (40,571 ) (96 ) (54,381 ) (523 ) (95,571 ) Cash collateral paid 56,005 — — — 56,005 Balance sheet line item totals $ 107,863 $ 949 $ (46,942 ) $ (505 ) $ 61,365 March 31, 2019 (in thousands) Commodity Derivative Assets - Current Commodity Derivative Assets - Noncurrent Commodity Derivative Liabilities - Current Commodity Derivative Liabilities - Noncurrent Total Commodity derivative assets $ 142,262 $ 3,781 $ 665 $ 93 $ 146,801 Commodity derivative liabilities (5,736 ) (24 ) (67,288 ) (3,914 ) (76,962 ) Cash collateral paid 21,751 — — — 21,751 Balance sheet line item totals $ 158,277 $ 3,757 $ (66,623 ) $ (3,821 ) $ 91,590 The net pretax gains and losses on commodity derivatives not designated as hedging instruments included in the Company’s Condensed Consolidated Statements of Operations and the line item in which they are located for the three and three months ended March 31, 2020 and 2019 are as follows: Three months ended March 31, (in thousands) 2020 2019 Gains on commodity derivatives included in cost of sales and merchandising revenues $ 30,960 $ 66,419 The Company had the following volume of commodity derivative contracts outstanding (on a gross basis) at March 31, 2020 , December 31, 2019 and March 31, 2019 : March 31, 2020 Commodity (in thousands) Number of Bushels Number of Gallons Number of Pounds Number of Tons Non-exchange traded: Corn 555,782 — — — Soybeans 33,950 — — — Wheat 92,374 — — — Oats 56,582 — — — Ethanol — 103,252 — — Corn oil — — 6,275 — Other 18,734 1,500 296 2,010 Subtotal 757,422 104,752 6,571 2,010 Exchange traded: Corn 165,295 — — — Soybeans 37,875 — — — Wheat 59,135 — — — Oats 1,490 — — — Ethanol — 44,440 — — Propane — 11,760 — — Other — 11,970 — 213 Subtotal 263,795 68,170 — 213 Total 1,021,217 172,922 6,571 2,223 December 31, 2019 Commodity (in thousands) Number of Bushels Number of Gallons Number of Pounds Number of Tons Non-exchange traded: Corn 552,359 — — — Soybeans 34,912 — — — Wheat 100,996 — — — Oats 24,700 — — — Ethanol — 116,448 — — Corn oil — — 14,568 — Other 11,363 4,000 305 2,263 Subtotal 724,330 120,448 14,873 2,263 Exchange traded: Corn 221,740 — — — Soybeans 39,145 — — — Wheat 68,171 — — — Oats 2,090 — — — Ethanol — 175,353 — — Propane — 5,166 — — Other — 15 — 232 Subtotal 331,146 180,534 — 232 Total 1,055,476 300,982 14,873 2,495 March 31, 2019 Commodity (in thousands) Number of Bushels Number of Gallons Number of Pounds Number of Tons Non-exchange traded: Corn 624,612 — — — Soybeans 42,859 — — — Wheat 118,909 — — — Oats 26,361 — — — Ethanol — 233,420 — — Corn oil — — 6,733 — Other 5,574 2,032 6 2,508 Subtotal 818,315 235,452 6,739 2,508 Exchange traded: Corn 197,210 — — — Soybeans 47,860 — — — Wheat 103,955 — — — Oats 770 — — — Ethanol — 110,758 — — Gasoline — 12,936 — — Propane — 14,784 — — Other 2 — — 205 Subtotal 349,797 138,478 — 205 Total 1,168,112 373,930 6,739 2,713 Interest Rate and Other Derivatives The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The gains or losses on the derivatives are recorded in Other Comprehensive Income (Loss) and subsequently reclassified into interest expense in the same periods during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. At March 31, 2020 , December 31, 2019 and March 31, 2019 , the Company had recorded the following amounts for the fair value of the Company's other derivatives: (in thousands) March 31, 2020 December 31, 2019 March 31, 2019 Derivatives not designated as hedging instruments Interest rate contracts included in Other long-term liabilities $ (1,913 ) $ (1,007 ) $ (4,494 ) Foreign currency contracts included in Other current assets (Accrued expenses and other current liabilities) $ 440 $ 2,742 $ (344 ) Derivatives designated as hedging instruments Interest rate contracts included in Accrued expenses and other current liabilities $ (8,081 ) $ (3,118 ) $ — Interest rate contracts included in Other long-term assets (Other long-term liabilities) $ (22,620 ) $ (9,382 ) $ (4,552 ) The recording of derivatives gains and losses and the financial statement line in which they are located are as follows: Three months ended March 31, (in thousands) 2020 2019 Derivatives not designated as hedging instruments Interest rate derivative gains (losses) included in Interest income (expense), net $ (784 ) $ (990 ) Foreign currency derivative gains (losses) included in Other income (loss), net $ — $ (1,467 ) Derivatives designated as hedging instruments Interest rate derivative gains (losses) included in Other Comprehensive Income (Loss) $ (18,182 ) $ (4,991 ) Interest rate derivatives gains (losses) included in Interest income (expense), net $ (1,290 ) $ 165 Outstanding interest rate derivatives, as of March 31, 2020 , are as follows: Interest Rate Hedging Instrument Year Entered Year of Maturity Initial Notional Amount (in millions) Description Interest Rate Long-term Swap 2014 2023 $ 23.0 Interest rate component of debt - not accounted for as a hedge 1.9% Collar 2016 2021 $ 40.0 Interest rate component of debt - not accounted for as a hedge 3.5% to 4.8% Swap 2017 2022 $ 20.0 Interest rate component of debt - accounted for as a hedge 1.8% Swap 2018 2023 $ 10.0 Interest rate component of debt - accounted for as a hedge 2.6% Swap 2018 2025 $ 20.0 Interest rate component of debt - accounted for as a hedge 2.7% Swap 2018 2021 $ 40.0 Interest rate component of debt - accounted for as a hedge 2.6% Swap 2019 2021 $ 25.0 Interest rate component of debt - accounted for as a hedge 2.5% Swap 2019 2021 $ 50.0 Interest rate component of debt - accounted for as a hedge 2.5% Swap 2019 2025 $ 100.0 Interest rate component of debt - accounted for as a hedge 2.5% Swap 2019 2025 $ 50.0 Interest rate component of debt - accounted for as a hedge 2.5% Swap 2019 2025 $ 50.0 Interest rate component of debt - accounted for as a hedge 2.5% Swap 2020 2023 $ 50.0 Interest rate component of debt - accounted for as a hedge 0.8% Swap 2020 2023 $ 50.0 Interest rate component of debt - accounted for as a hedge 0.7% Swap 2020 2030 $ 50.0 Interest rate component of debt - accounted for as a hedge 0.0% to 0.8% Swap 2020 2030 $ 50.0 Interest rate component of debt - accounted for as a hedge 0.0% to 0.8% |
