Pork Division

Seaboard’s Pork division is a vertically integrated pork producer and one of the largest producers and processors in the U.S. Seaboard is able to efficiently control pork production across the entire life cycle of a hog, beginning with research and development in nutrition and genetics and extending to the production of high quality meat products at Seaboard’s and its affiliates’ processing and further processing facilities.

This division’s hog processing plant is located in Guymon, Oklahoma. The plant is a double-shift operation that processes approximately 20,500 hogs per day and generally operates at capacity. Weekend shifts are added as market conditions dictate. Hogs processed at the plant are primarily Seaboard-raised hogs. The remaining hogs processed are raised by third parties and purchased under contract or occasionally in the open market. Seaboard produces and sells fresh and frozen pork products to further processors, food service operators, grocery stores, distributors and retail outlets throughout the U.S., Japan, Mexico, China and numerous other foreign markets.

Seaboard’s hog production facilities consist of genetic and commercial breeding, farrowing, nursery and finishing buildings located in the Central U.S. These facilities have a capacity to produce over five million hogs annually. Seaboard owns and operates seven centrally located feed mills to provide formulated feed to these hogs.

Seaboard produces biodiesel at facilities in Guymon, Oklahoma, and St. Joseph, Missouri. The biodiesel is produced from pork fat supplied by Seaboard’s Guymon pork processing plant and from other animal fat or vegetable oil supplied by non-Seaboard facilities. The biodiesel is sold to fuel blenders for distribution and in the retail markets.

Seaboard’s Pork division has agreements with Triumph Foods, LLC (“Triumph”), an independent pork processor, and Seaboard Triumph Foods, LLC (“STF”), a 50% non-consolidated, pork-processing affiliate, to market substantially all of the pork products produced at Triumph’s plant in St. Joseph, Missouri, and STF’s plant in Sioux City, Iowa. The agreements enhance the efficiency of Seaboard’s sales and marketing efforts and expand Seaboard’s geographic footprint. STF’s plant, which began operations in September 2017, is designed to process about three million market hogs annually when operating a single shift. Seaboard and Triumph each supply hogs to be processed at the STF plant. During 2017, the Pork division acquired hog inventory and related assets that provided additional sows to further increase its capacity to fulfill its hog supply commitment for processing at the STF plant, including its hog supply commitment for a second shift expansion. According to the trade publications Successful Farming and Informa Economics Seaboard was ranked number three in pork production (based on sows in production) and number four (based on daily processing capacity, including Triumph’s and STF’s capacities) in processing in the U.S. in 2017.

Seaboard’s Pork division also has a 50% noncontrolling interest in Daily’s Premium Meats, LLC (“Daily’s”). Daily’s produces and markets raw and pre-cooked bacon and ham primarily for the food service industry and, to a lesser extent, retail markets. Daily’s has three further processing plants located in Salt Lake City, Utah, Missoula, Montana, and St. Joseph, Missouri. Seaboard, Triumph and STF each supply raw product to Daily’s.

Commodity Trading and Milling Division

Seaboard’s Commodity Trading and Milling (“CT&M”) division is an integrated agricultural commodity trading, processing and logistics operation. This division sources, transports and markets approximately ten million metric tons per year of wheat, corn, soybeans, soybean meal and other commodities primarily to third-party customers and affiliated companies. These commodities are purchased worldwide, with primary destinations in Africa, South America, the Caribbean and Asia. This division integrates the delivery of commodities to its customers through the use of owned or chartered bulk vessels.

Seaboard’s CT&M division operates facilities in 28 countries. The commodity trading business has 13 offices in 12 countries, in addition to four non-consolidated affiliates in three other countries. The grain processing businesses operate facilities at 38 locations in 20 countries, with wheat flour mills in 16 countries, and include 6 consolidated and 18 non-consolidated affiliates primarily in Africa, South America, the Caribbean and Europe. Seaboard and its affiliates produce approximately five million metric tons of wheat flour, maize meal, manufactured feed and oilseed crush commodities per year in addition to other related grain-based products. In addition, on January 5, 2018, the CT&M division acquired five entities operating as Groupe Mimran (“Mimran”). Mimran operates three flour mills and an associated trading business located in Senegal, Ivory Coast and Monaco.

Marine Division

Seaboard’s Marine division provides cargo shipping services between the U.S., the Caribbean and Central and South America. This division’s primary operations, located in Miami, include an off-port warehouse for cargo consolidation and temporary storage and a terminal at PortMiami. At the Port of Houston, Seaboard’s Marine division operates a cargo terminal facility that includes on-dock warehouse space for temporary storage of bagged grains, resins and other cargoes. Seaboard also makes scheduled vessel calls to Brooklyn, New Orleans, Philadelphia and various ports in the Caribbean and Central and South America.

This division’s fleet consists of chartered and, to a lesser extent, owned vessels, and includes dry, refrigerated and specialized containers and other cargo related equipment. Seaboard’s Marine division is the largest shipper in terms of cargo volume in PortMiami and provides extensive service between its domestic ports of call and multiple foreign destinations.

To maximize fleet utilization, Seaboard’s Marine division uses a network of offices and agents throughout the U.S., Canada, the Caribbean and Central and South America to sell freight at multiple points. Seaboard’s full service capabilities allow transport by truck or rail of import and export cargo to and from various U.S. ports. Seaboard’s frequent sailings and fixed-day schedules allow customers to coordinate manufacturing schedules and maintain inventories at cost-efficient levels.

Sugar Division

In Argentina, Seaboard’s Sugar division grows sugarcane, which it uses to produce refined sugar and alcohol. The sugar is primarily marketed locally, with some exports to the U.S. and other countries. Seaboard’s sugar processing plant, one of the largest in Argentina, has an annual capacity to produce approximately 250,000 metric tons of sugar and approximately 27 million gallons of alcohol per year. The mill is located in the Salta Province of Argentina, with administrative offices in Buenos Aires. Land owned by Seaboard in Argentina is planted primarily with sugarcane, which supplies the majority of the raw material processed. Depending on local market conditions, sugar and alcohol may also be purchased from third parties for resale. In addition, Seaboard’s Sugar division sells dehydrated alcohol to certain oil companies under the Argentine governmental bio-ethanol program, which requires alcohol to be blended with gasoline. This division also owns a 51 megawatt cogeneration power plant, which is fueled by the burning of sugarcane by-products, natural gas and other biomass when available.

Power Division

In the Dominican Republic, Seaboard’s Power division is an unregulated independent power producer generating electricity for the local power grid from an owned barge with a capacity to generate 108 megawatts. This division primarily sells power on the spot market and is not directly involved in the transmission or distribution of electricity, and its principal buyers are government-owned distribution companies.

Other Division

Seaboard has a 50% noncontrolling voting interest in Butterball, LLC (“Butterball”). Butterball is one of the largest vertically integrated producers, processors and marketers of branded and non-branded turkey products in the U.S. Butterball has four processing plants, two further processing plants and numerous live production and feed milling operations located in North Carolina, Arkansas, Missouri and Kansas. Butterball produces over one billion pounds of turkey each year. Butterball is a national supplier to retail stores, foodservice outlets and industrial entities, and also exports products to Mexico and numerous other foreign markets.

The Securities and Exchange Commission requires a five-year comparison of stock performance for Seaboard with that of an appropriate broad equity market index and similar industry index. Seaboard’s common stock is traded on the NYSE American and provides an appropriate comparison for Seaboard’s stock performance. In July 2017, the NYSE MKT exchange transitioned to the NYSE American exchange. Because there is no single industry index to compare stock performance, the companies comprising the Dow Jones Food and Marine Transportation Industry indices (the “Peer Group”) were chosen as the second comparison.

The following graph shows a five-year comparison of cumulative total return for Seaboard Corporation, the NYSE American Index and the companies comprising the Dow Jones U.S. Food Products and the Dow Jones U.S.  Marine Transportation indices, weighted by market capitalization for the five fiscal years commencing December 31, 2012 and ending December 31, 2017. The information presented in the performance graph is historical in nature and is not intended to represent or guarantee future returns.

The comparison of cumulative total returns presented in the above graph was plotted using the following index values and common stock price values:

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

Seaboard is a diverse global agribusiness and transportation company with operations in several industries. Most of the sales and costs of Seaboard’s segments are significantly influenced by worldwide fluctuations in commodity prices and changes in foreign political and economic conditions. Accordingly, sales, operating income and cash flows can fluctuate significantly from year to year. As each segment operates in a distinct industry and a different geographical location, management evaluates their operations separately. Seaboard’s reporting segments are based on information used by Seaboard’s Chief Executive Officer in his capacity as chief operating decision maker to determine allocation of resources and assess performance.

Pork Segment

The Pork segment is primarily a United States (“U.S.”) business with some export sales to Japan, Mexico, China and numerous other foreign markets. Revenues from the sale of pork products are primarily generated from a single hog processing plant in Guymon, Oklahoma, which generally operates at daily double-shift processing capacity of approximately 20,500 hogs, and a ham boning and processing plant in Mexico. In 2017, Seaboard raised approximately 87% of the hogs processed at the Guymon plant, with the remaining hog requirements purchased primarily under contracts from independent producers. This segment is Seaboard’s most capital intensive segment, representing approximately 58% of Seaboard’s total fixed assets, in addition to 44% of total inventories.

Within the portfolio of Seaboard’s businesses, management believes profitability of the Pork segment is most susceptible to commodity price fluctuations. As a result, this segment’s operating income and cash flows can materially fluctuate from year to year, significantly affecting Seaboard’s consolidated operating income and cash flows. Sales prices are directly affected by both domestic and worldwide supply and demand for pork products and other proteins. Feed accounts for the largest input cost in raising hogs and is materially affected by price changes for corn and soybean meal. Market prices for hogs purchased from third parties for processing at the plant also represent a major cost factor. With the Guymon plant generally operating at capacity, Seaboard is continually looking for ways to enhance the plant’s operational efficiency, while also looking to increase margins by introducing new, higher value products.

The Pork segment also produces biodiesel, which is sold to third parties. Biodiesel is produced from pork fat from Seaboard’s pork processing plant and from other animal fat or vegetable oil purchased from third parties.

The Pork segment has a 50% noncontrolling interest in Seaboard Triumph Foods, LLC (“STF”), which operates a pork processing plant in Sioux City, Iowa, that began operations in September 2017. Seaboard has agreements with Triumph Foods, LLC (“Triumph”) and STF to market substantially all of the pork products produced at Triumph’s plant in St. Joseph, Missouri and STF’s pork processing plant. The STF plant is designed to process about three million market hogs annually when operating a single shift. Seaboard’s sales prices for its pork products are primarily based on a margin sharing arrangement that considers the average sales price and mix of products sold from the Seaboard, Triumph and STF hog processing plants. Seaboard and Triumph each agreed to provide a portion of the hogs to be processed at the STF plant. During 2017, the Pork segment acquired hog inventory and related assets to further increase its capacity to fulfill the hog supply commitment for single and double shift processing at the STF plant.

The Pork segment also has a 50% noncontrolling interest in Daily’s Premium Meats, LLC (“Daily’s”). Daily’s produces and markets raw and pre-cooked bacon and ham primarily for the food service industry and, to a lesser extent, retail markets. Daily’s has three further processing plants located in Salt Lake City, Utah, Missoula, Montana, and St. Joseph, Missouri.

Commodity Trading and Milling Segment

The Commodity Trading and Milling (“CT&M”) segment, which is managed under the name of Seaboard Overseas and Trading Group, primarily operates overseas and is an integrated agricultural commodity trading, processing and logistics operation with locations in Africa, South America, the Caribbean, Asia and Europe. These foreign operations can be significantly impacted by changes in local crop production, political instability and local government policies, as well as fluctuations in economic and industry conditions and foreign currency exchange rates. This segment’s sales are also significantly affected by fluctuating prices of various commodities, such as wheat, corn, soybeans and soybean meal. Although this segment owns three vessels, the majority of the trading business is transacted with chartered ships. Freight rates, influenced by available charter capacity for worldwide trade in bulk cargoes, and related fuel costs affect business volumes and margins. Consolidated and non-consolidated affiliates operate the grain processing businesses in foreign

countries that are in most cases lesser developed. Flour exports of various countries can exacerbate volatile market conditions that may have a significant impact on both the trading and milling businesses’ sales and operating income. This segment represents approximately 44% of Seaboard’s total inventories at December 31, 2017.

The majority of CT&M segment’s sales are derived from its commodity trading business in which agricultural commodities are sourced from multiple origins and delivered to third-party and affiliate customers in various international locations. The execution of these purchase and delivery transactions have long cycles of completion, which may extend for several months with a high degree of price volatility. As a result, these factors can significantly affect sales volumes, operating income, working capital and related cash flows from quarter to quarter. Profit margins are sometimes protected by using commodity derivatives and other risk management practices. Seaboard’s CT&M segment invested in several entities in recent years and continues to seek opportunities to expand its trading, milling and agro-processing business.

Marine Segment

The Marine segment provides cargo shipping services primarily between the U.S. and 28 countries in the Caribbean and Central and South America. Fluctuations in economic conditions and political instability in the regions or countries in which this segment operates may affect trade volumes and operating profits. In addition, cargo rates can fluctuate depending on local supply and demand for shipping services. The Marine segment time-charters the majority of its ocean cargo vessels and is therefore affected by fluctuations in charter hire rates as well as fuel costs. This segment continues to explore ways to increase volumes on existing routes while seeking opportunities to broaden its route structure in the regions it serves.

Sugar Segment

The Sugar segment operates a vertically integrated sugar and alcohol production facility in Argentina. This segment’s sales and operating income are significantly affected by local and worldwide sugar and alcohol prices. Domestic sugar production levels in Argentina affect the local price. Global sugar price fluctuations, to a lesser extent, have an impact in Argentina as well. Depending on local market conditions, this segment purchases sugar and alcohol from third parties for resale. The Sugar segment sells dehydrated alcohol to certain oil companies under an Argentine government bio-ethanol program, which mandates that alcohol be blended with gasoline. This segment also owns a 51 megawatt cogeneration power plant, which is fueled by the burning of sugarcane by-products, natural gas and other biomass when available. The functional currency of the Sugar segment is the Argentine peso. The currency exchange rate can have an impact on reported U.S. dollar sales, operating income and cash flows. Seaboard continues to explore various ways to improve and expand this segment, investing in efficiency improvements and production capacity increases.

Power Segment

The Power segment is an unregulated independent power producer in the Dominican Republic generating electricity for the local power grid from a system of diesel engines mounted on a barge. Seaboard sells power on the spot market primarily to government-owned distribution companies. This segment is subject to delays in obtaining timely collections from sales to these government-related entities. Supply of power in the Dominican Republic is determined by a government body and is subject to fluctuations based on governmental budgetary constraints. While fuel is this segment’s largest cost component and is subject to price fluctuations, higher fuel costs generally have been passed on to customers.

Turkey Segment

Seaboard has a 50% noncontrolling voting interest in Butterball, LLC (“Butterball”). Butterball is a vertically integrated producer, processor and marketer of branded and non-branded turkey products. Butterball has four processing plants, two further processing plants and numerous live production and feed milling operations located in North Carolina, Arkansas, Missouri and Kansas. During 2017, Butterball closed its Montgomery, Illinois, further processing plant, which was sold during the first quarter of 2018. Sales prices are directly affected by both domestic and worldwide supply and demand for turkey products and other proteins. Feed accounts for the largest input cost in raising turkeys and is materially affected by price changes for corn and soybean meal. As a result, commodity price fluctuations can significantly affect the profitability and cash flows of Butterball. The turkey business is seasonal only on the whole bird side, with the Thanksgiving and Christmas holidays driving the majority of those sales.

LIQUIDITY AND CAPITAL RESOURCES

Summary of Sources and Uses of Cash

Cash and short-term investments as of December 31, 2017 increased $338 million from December 31, 2016. The increase was primarily the result of net cash from operating activities of $245 million, repayments of affiliate notes receivable of $167 million and proceeds from short-term and long-term debt of $83 million. Partially offsetting the increase was cash

used for capital expenditures of $173 million. Cash from operating activities decreased $182 million from 2016 primarily as a result of lower net earnings including adjustments and working capital changes.

Cash and short-term investments as of December 31, 2016 increased $50 million from December 31, 2015. The increase was primarily the result of net cash from operating activities of $427 million, net proceeds from short-term investments of $53 million and proceeds from sale of fixed assets of $47 million. Partially offsetting the increase was cash used for acquisition of businesses of $219 million, capital expenditures of $158 million, investments in affiliates of $71 million and purchase of long-term investments of $31 million. Cash from operating activities increased $11 million for 2016 primarily as a result of higher net earnings, partially offset by working capital changes.

Capital Expenditures, Acquisitions and Other Investing Activities

During 2017, Seaboard invested $173 million in property, plant and equipment, of which $100 million was in the Pork segment, $15 million in the CT&M segment, $37 million in the Marine segment and $20 million in the Sugar segment. The Pork segment expenditures were primarily for improvements to existing facilities and related equipment and additional hog finishing barns. The Sugar segment expenditures were primarily related to a new bioethanol distillery. All other capital expenditures were primarily of a normal recurring nature and included replacements of machinery and equipment, and general facility modernizations and upgrades.

The total 2018 capital expenditures budget is $271 million. The Pork segment budgeted $115 million primarily for improvements to existing facilities and related equipment and additional hog finishing barns. The CT&M segment budgeted $48 million primarily for milling assets and other improvements to existing facilities and related equipment. The Marine segment budgeted $81 million primarily for additional cargo carrying and handling equipment and port improvements. The Sugar segment budgeted $26 million primarily for increasing the milling capacity and improving logistics infrastructure. The balance of $1 million is planned to be spent in all other businesses primarily for normal upgrades to existing operations. Management anticipates paying for these capital expenditures from a combination of available cash, the use of available short-term investments and Seaboard’s available borrowing capacity.

During 2016, Seaboard invested $158 million in property, plant and equipment, of which $69 million was in the Pork segment, $35 million in the CT&M segment, $19 million in the Marine segment and $34 million in the Sugar segment. The Pork segment expenditures were primarily for improvements to existing facilities and related equipment, additional hog finishing barns and the June 2016 purchase and improvement of a biodiesel plant in St. Joseph, Missouri, for $6 million that became operational in the third quarter. Of the CT&M segment expenditures, $29 million was for the construction of two dry bulk vessels, which were delivered and then sold and leased back by Seaboard at book value of $44 million during the first quarter of 2016. The Marine segment expenditures were primarily for purchases of cargo carrying and handling equipment. The Sugar segment expenditures were primarily for milling capacity increase and fermentation and distillery equipment upgrades. All other capital expenditures were primarily of a normal recurring nature and included replacements of machinery and equipment, and general facility modernizations and upgrades.

During 2015, Seaboard invested $139 million in property, plant and equipment, of which $40 million was in the Pork segment, $40 million in the CT&M segment and $43 million in the Marine segment. The Pork segment expenditures were primarily for improvements to existing facilities and related equipment and additional hog finishing barns. Of the CT&M segment expenditures, $30 million was for the construction of dry bulk vessels, two of which were delivered and then sold and leased back by Seaboard at book value of $44 million in 2015. The Marine segment expenditures were primarily for purchases of cargo carrying and handling equipment and $8 million for the purchase of a containerized cargo vessel. All other capital expenditures were of a normal recurring nature and primarily included replacements of machinery and equipment, and general facility modernizations and upgrades.

During 2017, 2016 and 2015, Seaboard contributed $73 million, $51 million and $26 million, respectively, to STF for construction of a pork processing plant in Sioux City, Iowa, which began operations in September 2017. In addition to capital contributions, Seaboard also agreed to provide a portion of the hogs to be processed at the plant, including a portion of those needed for a second shift expansion. During 2016, Seaboard acquired hog inventory and related assets through acquisitions of existing farm operations for a total investment of $219 million. These assets increased Seaboard’s hog production capacity to meet the majority of such hog supply commitment for single-shift processing at the new plant. During 2017, Seaboard acquired additional hog inventory and hog farms to further increase its capacity. See Note 12 to the consolidated financial statements for further discussion of the significant acquisitions.

Also during 2017, Seaboard’s CT&M segment acquired a pulse and grain elevator in Canada for total cash consideration of $14 million, and invested an additional $7 million in a grain trading and poultry business in Morocco, increasing its

ownership interest in this Moroccan business to 19.4%. See Note 12 to the consolidated financial statements for further information on the elevator purchase and Note 4 to the consolidated financial statements for further discussion of this investment.

On January 5, 2018, the CT&M segment completed the acquisition of Groupe Mimran (“Mimran”), including three flour mills in Senegal and Ivory Coast having a combined capacity of approximately 2,750 metric tons a day, and a trading business located in Monaco that is expected to increase Seaboard’s annual grain trading volume by approximately 900,000 tons. The purchase price was $375 million, plus an earn-out between zero and $48 million, using the exchange rate in effect at closing.

Seaboard purchased equity interests in two limited liability companies that operate refined coal processing plants, one in Oklahoma during 2015 and one in Nebraska during 2016. Production of refined coal generates federal income tax credits. Seaboard’s funding commitment for these companies varies depending on production and, based on current production estimates, is anticipated to total approximately $14 million per year until 2021, for a total estimate of approximately $52 million as of December 31, 2017. Seaboard invested $10 million, $14 million and $9 million during 2017, 2016 and 2015, respectively.

In 2016, Seaboard invested $7 million of cash and converted its $8 million note receivable to equity for a 36% noncontrolling interest in a holding company that owns a Caribbean start-up terminal operation. The investment is accounted for in the Marine segment using the equity method and reported on a three-month lag.

During 2016 and 2015, Seaboard invested an additional $14 million and $28 million, respectively, in equity and long-term advances in a flour production business in Brazil, of which Seaboard now holds a 98% controlling interest. See Note 4 to the consolidated financial statements for further discussion of this investment.

During 2015, the CT&M and Power segments invested in several businesses. Seaboard’s CT&M segment contributed $13 million in cash, a small amount of other assets, certain employees and rights to sell certain agricultural commodities that Seaboard had previously sold through its subsidiary, PS International, LLC, for a 40% noncontrolling interest in a commodity trading business in Atlanta, Georgia. Also, Seaboard invested $8 million in a flour milling business in Botswana for a 49% noncontrolling interest, $10 million for a 45% noncontrolling interest in a commodity trading and flour milling business in Uruguay, $10 million in an oilseed crushing business in the Republic of Turkey for a 25% noncontrolling interest, and $18 million for a 12% noncontrolling interest in a grain trading and poultry business in Morocco, which at the time was accounted for using the cost method. During 2015, the Power segment invested $10 million in a business operating a 300 megawatt electricity generating facility in the Dominican Republic, increasing Seaboard’s ownership interest to 29.9%. See Note 4 to the consolidated financial statements for further discussion.

Financing Activities, Debt and Related Covenants

The following table presents a summary of Seaboard’s available borrowing capacity as of December 31, 2017. At December 31, 2017, borrowings under the uncommitted lines of credit totaled $162 million, with $115 million of borrowings related to foreign subsidiaries. See Note 7 to the consolidated financial statements for further discussion.

In 2017, Seaboard renewed its $100 million committed line of credit with Wells Fargo Bank, National Association (“Wells Fargo”) for another year until September 28, 2018. Interest is computed at LIBOR plus 0.50%, and Seaboard incurs an unused commitment fee of 0.09% per annum. This line of credit is secured by certain short-term investments and is subject to standard representations and covenants. There was no outstanding balance as of December 31, 2017.

At December 31, 2017, Seaboard had an unsecured term loan, which matures in 2022, with a balance of $484 million and $52 million of foreign subsidiary debt, primarily denominated in Argentine pesos. Seaboard was in compliance with all restrictive covenants related to these loans and facilities as of December 31, 2017. Seaboard has capacity under existing loan covenants to undertake additional debt financings of approximately $1,533 million at December 31, 2017. See Note 7 to the consolidated financial statements for further discussion of notes payable and long-term debt.

As of December 31, 2017, Seaboard had cash and short-term investments of $1,692 million and additional total working capital of $618 million. Accordingly, management believes Seaboard’s combination of internally generated cash, liquidity, capital resources and borrowing capabilities will be adequate for its existing operations and any currently known potential plans for expansion of existing operations or business segments for 2018. Management intends to continue seeking opportunities for expansion in the industries in which Seaboard operates, utilizing existing liquidity, available borrowing capacity and other financing alternatives.

As of December 31, 2017, $380 million of the $1,692 million of cash and short-term investments were held by Seaboard’s foreign subsidiaries. Historically, Seaboard has considered substantially all foreign profits as being permanently invested in its foreign operations, including all cash and short-term investments held by foreign subsidiaries. Seaboard intends to continue permanently reinvesting these funds outside the U.S. as current plans do not demonstrate a need to repatriate them to fund Seaboard’s U.S. operations and therefore, Seaboard has not recorded deferred taxes for state or foreign withholding taxes that would result upon repatriation to the U.S. However,  with the December 22, 2017 enactment of the Tax Cuts and Job Act (the “2017 Tax Act”), Seaboard accrued a provisional $112 million of federal tax in its consolidated financial statements as of December 31, 2017 associated with the mandatory deemed repatriation of these balances. See Note 6 to the consolidated financial statements for further discussion on the tax reform.

No shares of common stock were repurchased by Seaboard in 2017, 2016 or 2015. In each of the four quarters of 2017, Seaboard declared and paid quarterly dividends of $1.50 per share of common stock. Seaboard’s Board of Directors intends that Seaboard will continue to pay quarterly dividends for the reasonably foreseeable future, with the amount of any dividends being dependent upon such factors as Seaboard’s financial condition, results of operations and current and anticipated cash needs, including capital requirements. There were no dividends paid in 2016 or 2015. See Note 11 to the consolidated financial statements for further discussion on stockholders’ equity.

Contractual Obligations and Off-Balance Sheet Arrangements

The following table provides a summary of Seaboard’s contractual obligations as of December 31, 2017.

(a)  Interest payments in the table above include cash payments for interest on variable rate long-term debt based on interest rates as of December 31, 2017.

(b)  Retirement benefit payments in the table above represent expected benefit payments for various non-qualified pension plans and supplemental retirement arrangements as discussed in Note 9 to the consolidated financial statements, which are unfunded obligations that are deemed to be employer contributions. No contributions are planned at this time to the qualified pension plan.

(c)  U.S. federal income tax on mandatory deemed repatriation is payable over eight years pursuant to the 2017 Tax Act.

(d)  Investment in affiliates represents obligations made to equity method investments, primarily for expected funding commitments to two limited liability companies that operate refined coal processing plants.

Several of Seaboard’s segments have long-term contractual obligations, including non-cancelable operating lease agreements for facilities and equipment. The Marine and CT&M segments enter into contracts to time-charter vessels for use in operations. The Pork segment has contract grower agreements in place with farmers to raise a portion of Seaboard’s hogs to support its operations. The Pork segment has also entered into grain and feed ingredient purchase contracts to support the segment’s live hog operations, and has contracted for the purchase of additional hogs from third parties. The CT&M segment enters into commodity purchase contracts, primarily to support sales commitments. See Note 10 to the consolidated financial statements for further discussion on Seaboard’s contractual obligations and for a more detailed listing of other purchase commitments.

Non-current deferred income taxes and certain other long-term liabilities on the consolidated balance sheets are not included in the table above as management is unable to reliably estimate the timing of the payments for these items. In addition, deferred revenues and other deferred credits included in other long-term liabilities on the consolidated balance sheets have been excluded from the table above because they do not represent contractual obligations.

RESULTS OF OPERATIONS

Net sales for the years ended December 31, 2017, 2016 and 2015 were $5,809 million, $5,379 million and $5,594 million, respectively. The increase for 2017 compared to 2016 primarily reflected higher sales prices and volumes for certain commodities in the CT&M segment, higher overall prices for pork products sold, higher sales volume of market hogs and higher biodiesel revenue in the Pork segment, higher cargo volumes in the Marine segment and higher selling prices and volumes for alcohol in the Sugar segment. The decrease for 2016 compared to 2015 primarily reflected lower commodity prices and the mix of products sold for the CT&M segment, lower volumes of sugar sold in the Sugar segment, and lower cargo rates in the Marine segment, partially offset by higher sales volume of market hogs from 2016 acquisitions of live operations and higher biodiesel volumes from the acquisition of a second biodiesel plant in the Pork segment.

Operating income for the years ended December 31, 2017, 2016 and 2015 were $232 million, $222 million and $126 million, respectively. The increase for 2017 compared to 2016 primarily reflected higher margins from sugar in the Sugar segment and higher margins from meat prices in the Pork segment, partially offset by lower margins on biodiesel in the Pork segment, lower margins on commodities in the CT&M segment and lower cargo rates and higher fuel costs in the Marine segment. The increase for 2016 compared to 2015 primarily reflected lower feed costs for hogs internally grown in the Pork segment and higher margins on commodity trades to third parties in the CT&M segment, partially offset by higher production costs for sugar in the Sugar segment.

Pork Segment

Net sales for the Pork segment increased $166 million for the year ended December 31, 2017 compared to 2016. The increase was primarily the result of higher overall prices for pork products sold, higher sales volume of market hogs related to the August 2017 acquisition, higher biodiesel revenue and, to a lesser extent, a higher volume of pork products sold internationally.

Operating income for the Pork segment increased $13 million for the year ended December 31, 2017 compared to 2016. The increase was primarily the result of improved overall margins from higher meat prices and market hog sales, partially offset by lower biodiesel margins because the Federal blender’s credits were not renewed during 2017. In February 2018, Congress retroactively extended the Federal blender’s credits for 2017 which will cause Seaboard to recognize approximately $42 million of revenue in the first quarter of 2018. Management is unable to predict future market prices for pork products, the cost of feed or third-party hogs or the government’s intentions with the Federal blenders’ credits; however, management anticipates positive operating income for this segment in 2018.

Income from affiliates decreased $21 million for the year ended December 31, 2017 compared to 2016, primarily due to the start-up of STF operations, which began in September 2017, partially offset by earnings from its other non-consolidated affiliate, Daily’s.

Net sales for the Pork segment increased $111 million for the year ended December 31, 2016 compared to 2015. The increase was primarily the result of higher sales volume of market hogs related to 2016 acquisitions, higher prices for pork products sold and increased volume and sales prices for biodiesel resulting from increased output from the Guymon plant and the acquisition of a second biodiesel plant in St. Joseph, Missouri, during 2016. The increase was partially offset by lower volume of pork products sold.

Operating income for the Pork segment increased $59 million for the year ended December 31, 2016 compared to 2015. The increase was primarily the result of lower feed costs for hogs internally grown and improved overall margins from higher meat prices.

Income from affiliates for the Pork segment in 2016 and 2015 was solely from Seaboard’s 50% ownership interest in Daily’s, accounted for using the equity method.

Commodity Trading and Milling Segment

Net sales for the CT&M segment increased $167 million for the year ended December 31, 2017 compared to 2016. The increase primarily reflected higher sales prices for wheat sales to third parties and higher volumes of sales to affiliates and third parties, partially offset by lower corn and soybean meal sales prices and volumes to third parties.

Operating income for the CT&M segment decreased $13 million for the year ended December 31, 2017 compared to 2016. The decrease primarily reflected lower margins on commodities and higher selling, general and administrative expense, partially offset by higher gains of $4 million on mark-to-market derivative contracts as further discussed below. Excluding the effects of the mark-to-market adjustments for derivatives contracts, operating income decreased $17 million primarily due to a decrease in commodity prices in the pulse market.

Due to worldwide commodity price fluctuations, the uncertain political and economic conditions in the countries in which Seaboard operates, and the current volatility in the commodity markets, management is unable to predict future sales and operating results for this segment. However, management anticipates positive operating income for this segment in 2018, excluding the effects of marking to market derivative contracts.

Had Seaboard not applied mark-to-market accounting to its derivative instruments, operating income for this segment would have been lower by $4 million in 2017, remained the same in 2016 and been lower by $5 million in 2015. While management believes its commodity futures, options and foreign exchange contracts are primarily economic hedges of its firm purchase and sales contracts or anticipated sales contracts, Seaboard does not perform the extensive record-keeping required to account for these transactions as hedges for accounting purposes. Accordingly, while the changes in value of the derivative instruments were marked to market, the changes in value of the firm purchase or sales contracts were not. As products are delivered to customers, these existing mark-to-market adjustments should be primarily offset by realized margins or losses as revenue is recognized over time and therefore, these mark-to-market adjustments could reverse in fiscal 2018. Management believes eliminating these mark-to-market adjustments provides a more reasonable presentation to compare and evaluate period-to-period financial results for this segment.

Income from affiliates for the CT&M segment increased by $17 million for the year ended December 31, 2017 compared to 2016. The increase primarily reflected consolidation of an equity method investment that incurred $10 million of losses during 2016. See Note 4 to the consolidated financial statements for further discussion of this affiliate. Based on the uncertainty of local political and economic environments in the countries in which Seaboard’s affiliates operate, management cannot predict future results.

Net sales for the CT&M segment decreased $244 million for the year ended December 31, 2016 compared to 2015. The decrease primarily reflected lower sales prices, resulting from lower commodity prices and the mix of products sold, partially offset by higher volumes in corn and soybeans.

Operating income for the CT&M segment increased $36 million for the year ended December 31, 2016 compared to 2015. The increase primarily reflected higher margins on commodity trades to third parties and affiliates and fluctuations of $5

million of mark-to-market derivative contracts. Excluding the effects of mark-to-market adjustments for derivatives contracts, operating income increased $41 million.

Loss from affiliates for the CT&M segment decreased $40 million for the year ended December 31, 2016 compared to 2015. The decrease primarily reflected lower operating and currency losses recorded against the investment and lower reserves for notes receivable and advances from an affiliate in Brazil. Seaboard’s loss from this Brazilian affiliate totaled $60 million in 2015 compared to $10 million in 2016. This Brazilian affiliate was consolidated in the fourth quarter of 2016.

Marine Segment

Net sales for the Marine segment increased $40 million for the year ended December 31, 2017 compared to 2016. The increase was primarily the result of higher volumes in certain markets during 2017 compared to 2016, partially offset by lower cargo rates.

Operating income for the Marine segment decreased $12 million for the year ended December 31, 2017 compared to 2016. The decrease was primarily the result of lower cargo rates and higher fuel costs, partially offset by lower other voyage costs. Management cannot predict changes in future cargo volumes, cargo rates and fuel costs, or to what extent changes in economic conditions in markets served will affect net sales or operating income during 2018. However, management anticipates this segment will have positive operating income for 2018.

Income from affiliates decreased $8 million for the year ended December 31, 2017 compared to 2016 primarily due to an other-than-temporary impairment charge of $6 million related to Seaboard’s equity-method investment in a holding company that owns a start-up terminal operation. See Note 4 to the consolidated financial statements for further information on this affiliate.

Net sales for the Marine segment decreased $24 million for the year ended December 31, 2016 compared to 2015. The decrease was primarily the result of lower cargo rates in certain markets during 2016 compared to 2015, partially offset by higher volumes.

Operating income for the Marine segment increased $14 million for the year ended December 31, 2016 compared to 2015. The increase was primarily the result of lower voyage costs, principally fuel costs, on a per unit shipped basis, partially offset by lower cargo rates.

Sugar Segment

Net sales for the Sugar segment increased $39 million for the year ended December 31, 2017 compared to 2016. The increase primarily reflected higher volumes and selling prices of alcohol and higher selling prices for sugar, partially offset by lower volumes of sugar sold. Sugar and alcohol sales are denominated in Argentine pesos, and an increase in local sales prices in terms of U.S. dollars was partially offset by exchange rate changes as the Argentine peso continued to weaken against the U.S. dollar in 2017. Management cannot predict local sugar and alcohol prices for 2018, but management anticipates that the Argentine peso will continue to weaken against the U.S. dollar.

Operating income for the Sugar segment increased $33 million for the year ended December 31, 2017 compared to 2016. The increase primarily reflected higher margins from sugar, alcohol and cogeneration primarily related to increased selling prices, partially offset by higher selling, general and administrative costs. During 2016, labor strikes and inclement weather negatively impacted volumes and resulted in a $12 million inventory charge. Based on recent market conditions, management currently cannot predict if this segment will be profitable in 2018.

Net sales for the Sugar segment decreased $41 million for the year ended December 31, 2016 compared to 2015. The decrease primarily reflected lower volumes and lower selling prices of sugar sold. During the third and fourth quarters of 2016, labor strikes and inclement weather negatively impacted volumes and resulted in a $12 million inventory charge to cost of sales for fixed manufacturing costs associated with the revised production forecasts. Sugar and alcohol sales are denominated in Argentine pesos, and an increase in local sales prices in terms of U.S. dollars was principally offset by exchange rate changes as the Argentine peso continued to weaken against the U.S. dollar in 2016.

Operating income for the Sugar segment decreased $14 million for the year ended December 31, 2016 compared to 2015. The decrease primarily reflected lower sales prices, lower volumes and the $12 million inventory charge, partially offset by reduced selling, general and administrative expenses from decreased personnel-related costs.

Power Segment

Net sales for the Power segment increased $18 million for the year ended December 31, 2017 compared to 2016. The increase primarily reflected higher spot market rates.

Operating income for the Power segment increased $2 million for the year ended December 31, 2017 compared to 2016 primarily due to higher spot market rates, partially offset by higher fuel costs. Management cannot predict future fuel costs or the extent that spot market rates will fluctuate compared to fuel costs; however, management anticipates positive operating income for this segment in 2018.

Net sales for the Power segment decreased $18 million for the year ended December 31, 2016 compared to 2015. The decrease primarily reflected lower spot market rates, which were attributable primarily to lower fuel costs, a component of pricing.

Operating income for the Power segment was flat for the year ended December 31, 2016 compared to 2015 primarily due to the lower spot market rates being offset by lower fuel costs per kilowatt hour generated and other lower production costs.

Turkey Segment

The Turkey segment, accounted for using the equity method, represents Seaboard’s investment in Butterball. The decrease in income from affiliate for 2017 compared to 2016 was primarily the result of lower prices for turkey products sold, pricing pressure from competing proteins and higher live growing costs. Also, the decrease included the 2017 closure of a further processing plant located in Montgomery, Illinois. Butterball’s closure and subsequent sale in 2018 of the plant, resulted in charges primarily related to impaired fixed assets and accrued severance. Seaboard’s proportionate share of these charges, recognized in income (loss) from affiliates, was $18 million, all of which was recorded in 2017. Management is unable to predict future market prices for turkey products or the cost of feed; however, management anticipates positive income for this segment in 2018.

The decrease in income from affiliate for 2016 compared to 2015 was primarily the result of lower volume and prices for turkey products sold.

Selling, General and Administrative Expenses

Selling, general and administrative (“SG&A”) expenses for the year ended December 31, 2017 increased $42 million over 2016 to $317 million. The increase was primarily the result of increased personnel-related costs, including costs related to Seaboard’s deferred compensation program, which were offset by the effect of the mark-to-market on investments recorded in other investment income. As a percentage of revenues, SG&A was 5% for 2017 and 2016.

SG&A expenses for the year ended December 31, 2016 increased $5 million over 2015 to $275 million. The increase was primarily the result of increased costs related to Seaboard’s deferred compensation program, which were offset by the effect of the mark-to-market on investments recorded in other investment income. As a percentage of revenues, SG&A was 5% for 2016 and 2015.

Interest Expense

Interest expense totaled $29 million, $29 million and $18 million for the years ended December 31, 2017, 2016 and 2015, respectively. The increase in 2016 compared to 2015 primarily related to long-term debt issued in December 2015.

Interest Income

Interest income totaled $15 million, $15 million and $40 million for the years ended December 31, 2017, 2016 and 2015, respectively. The decrease for 2016 compared to 2015 primarily reflected lower interest recognized on customer receivable balances in the Power segment. In December 2015, the Power segment recognized $31 million of interest income related to aged receivable balances. See Note 13 to the consolidated financial statements for further discussion.

Interest Income from Affiliates

Interest income from affiliates totaled $22 million, $24 million and $29 million for the years ended December 31, 2017, 2016 and 2015, respectively, and primarily relates to a Butterball note receivable, which was repaid in December 2017. The decrease for 2016 compared to 2015 primarily reflected the modification of a Butterball note receivable. See Note 4 to the consolidated financial statements for further discussion of the modification.

Other Investment Income (Loss), Net

Other investment income (loss), net totaled $177 million, $69 million and $(5) million for the years ended December 31, 2017, 2016 and 2015, respectively. The increase for 2017 compared to 2016 primarily reflects higher income on short-term investments related to mark-to-market fluctuation and dividends. The increase for 2016 compared to 2015 primarily reflects higher income on short-term investments related to mark-to-market fluctuation and dividends, partially offset by higher losses associated with its investments in refined coal processing plants, of which a portion is offset by tax credits in income tax expense.

Foreign Currency Gains, Net

Foreign currency gains, net totaled $14 million, $2 million and $1 million for the years ended December 31, 2017, 2016 and 2015, respectively. The increase in foreign currency gains, net in 2017 compared to 2016 primarily reflected gains in the euro and British pound on Seaboard’s short-term investments and the Zambian kwacha on Seaboard’s operations, partially offset by losses in the South African rand, among fluctuations of other currency exchange rates in several foreign countries. The increase in foreign currency gains, net in 2016 compared to 2015 primarily reflected gains in the South African rand, partially offset by losses in the Zambian kwacha, among fluctuations of other currency exchange rates in several foreign countries. The political and economic conditions of the countries in which Seaboard operates and does business, along with fluctuations in the value of the U.S. dollar cause volatility in currency exchange rates, which exposes Seaboard to fluctuating foreign currency gains and losses that cannot be predicted by Seaboard. Although Seaboard does not utilize hedge accounting, Seaboard does utilize foreign currency exchange contracts to manage its risks and exposure to foreign currency fluctuations. Management believes gains and losses on commodity transactions, including the mark-to-market effects, of such foreign currency exchange contracts relate to the underlying commodity transactions and classifies such gains and losses in cost of sales. All other gains and losses on foreign currency exchange contracts are included in foreign currency gains (losses), net.

Income Tax Expense

On December 22, 2017, the President of the U.S. signed into law the Tax Cuts and Job Act (the “2017 Tax Act”). The 2017 Tax Act changes U.S. tax law by, among other things, lowering corporate income tax rates, implementing a territorial tax system and imposing a repatriation tax on mandatory deemed repatriated earnings of foreign subsidiaries. The 2017 Tax Act permanently reduces the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018. The effective tax rate for 2017 was higher than 2016 primarily due to the enactment of the 2017 Tax Act, partially offset by the expiration of the U.S. biodiesel tax provisions on December 31, 2016 and lower tax credits in 2017. The effective tax rate reflects an increase in Seaboard’s taxes payable resulting from the one-time mandatory deemed repatriation charge and a decrease in value of Seaboard’s deferred tax assets due to the corporate rate decrease from 35% to 21%. This change was partially offset by reduced tax expense resulting from the rate decrease impact on the deferred tax liabilities.

OTHER FINANCIAL INFORMATION

Management does not believe its businesses have been materially adversely affected by inflation. See Note 1 to the consolidated financial statements for a discussion of recently issued accounting standards.

CRITICAL ACCOUNTING ESTIMATES

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the U.S. (“GAAP”) requires management 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 consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Management has identified the accounting estimates believed to be the most important to the portrayal of Seaboard’s financial condition and results, and that require management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Management has reviewed these critical accounting estimates with the Audit Committee of the Board of Directors.

Allowance for Doubtful Accounts – Seaboard primarily uses a specific identification approach to evaluate the adequacy of this reserve for estimated uncollectible receivables at the consolidated balance sheet date. Changes in estimates, developing trends and other new information can have a material affect on future evaluations. Furthermore, Seaboard’s total current receivables are heavily weighted toward foreign receivables ($343 million or 75% at December 31, 2017), including foreign receivables due from affiliates ($104 million at December 31, 2017), which generally represent more of a collection risk than its domestic receivables. Receivables due from affiliates are generally associated with entities located in foreign countries considered less developed than the U.S. that can experience conditions causing sudden changes to their ability to pay such receivables on a timely basis or in full. Based on various historical experiences, future collections of receivables or lack thereof could result in a material charge or credit to earnings depending on the ultimate resolution of each individual customer past due receivable. Bad debt expense for the years ended December 31, 2017, 2016 and 2015 was $12 million, $15 million and $13 million, respectively.

Valuation of Inventories – Inventories are generally valued at the lower of cost and net realizable value. In determining net realizable value, management makes assumptions regarding estimated sales prices, estimated costs to complete and estimated disposal costs. For commodity trading inventories, when contract performance by a customer becomes a concern, management must also evaluate available options to dispose of the inventory, including assumptions about potential negotiated changes to sales contracts, sales prices in alternative markets in various foreign countries and potentially additional transportation costs. At times, management must consider probability, weighting various viable alternatives, in its determination of the net realizable value of the inventories. These assumptions and probabilities are subjective in nature, and are based on management’s best estimates and judgments existing at the time of preparation. Changes in future market prices or facts and circumstances could result in a material write down in value of inventory or decreased future margins on the sale of inventory.

Impairment of Long-Lived Assets – At each balance sheet date, long-lived assets, primarily property, plant and equipment, are reviewed for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the asset group. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Some of the key assumptions utilized in determining future projected cash flows include estimated growth rates, expected future sales prices and estimated costs. In some cases, judgment is also required in assigning probability weighting to the various future cash flow scenarios. The probability weighting percentages used and the various future projected cash flow models prepared by management are based on facts and circumstances existing at the time of preparation and management’s best estimates and judgment of future operating results. Seaboard cannot predict the occurrence of certain future events that might adversely affect the reported value of long-lived assets, which include, but are not limited to, a change in the business climate, government incentives, a negative change in relationships with significant customers, and changes to strategic decisions made in response to economic and competitive conditions. Changes in these facts, circumstances and management’s estimates and judgment could result in an impairment of property, plant and equipment, resulting in a material charge to earnings.

Investments in and Advances to Affiliates and Notes Receivable From Affiliates – Seaboard has numerous investments in and advances to various businesses that it owns 50% or less for a noncontrolling interest and are accounted for using the equity method. In addition, for some of these investments, Seaboard also has notes receivable for loans it provided to these businesses. For the CT&M segment, these investments are primarily in foreign countries, which are less developed than the U.S., and therefore, expose Seaboard to greater financial risks. At certain times when there are ongoing operating losses, local economies are depressed, commodity-based markets are less stable, or foreign governments cause challenging business conditions, the fair value of the equity method investment is evaluated by management. The fair value of these

investments is not readily determinable as almost all of these investments are not publicly traded. Management will use other methods to determine fair value such as estimated future cash flows, including assumptions on growth rates, for the business and consideration of other local business conditions as applicable. If the fair value of the investment is determined to be less than the carrying value and the decline in value is considered to be other than temporary, an appropriate write down is recorded to income (loss) from affiliates based on the excess of the carrying value over the best estimate of fair value of the investment. In addition, if based on current information and events it is probable that Seaboard will be unable to collect all amounts due according to the contractual terms of the notes receivable from affiliates and an amount can be reasonably estimated, Seaboard will write down the amounts to estimated realizable value. Information and events creating uncertainty about the realization of recorded amounts for notes from affiliates include, but are not limited to, the estimated cash flows generated by the affiliate’s business, the sufficiency of collateral securing the amounts, the creditworthiness of the counterparties involved, and the consideration of other local business conditions as applicable. Changes in facts, circumstances and management’s estimates and judgment could result in a material charge to earnings. See Note 4 to the consolidated financial statements for further discussion on Seaboard’s affiliates.

Income Taxes – Income taxes are determined by management based on current tax regulations in the various worldwide taxing jurisdictions in which Seaboard conducts its business. In various situations, accruals have been made for estimates of the tax effects for certain transactions, business structures, the estimated reversal of timing differences and future projected profitability of Seaboard’s various business units based on management’s interpretation of existing facts, circumstances and tax regulations. The Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118 to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the 2017 Tax Act. Seaboard has recognized provisional tax impacts related to the mandatory deemed repatriated earnings and the revaluation of deferred tax assets and liabilities and included these amounts in its consolidated financial statements for the year ended December 31, 2017. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions Seaboard has made, additional regulatory guidance that may be issued, and actions Seaboard may take as a result of the 2017 Tax Act. The accounting is expected to be complete when the 2017 U.S. corporate income tax return is filed in 2018. See Note 6 to the consolidated financial statements for further discussion on income taxes.

Accrued Pension Liability – The measurement of Seaboard’s pension liability and related expense is dependent on a variety of assumptions and estimates regarding future events. These assumptions include discount rates, assumed rate of return on plan assets, compensation increases, turnover rates, mortality rates and retirement rates. The discount rate and return on plan assets are important elements of liability and expense measurement, and are reviewed on an annual basis. The effect of decreasing both the discount rate and assumed rate of return on plan assets by 50 basis points would be an increase in pension expense of approximately $3 million per year. The effects of actual results differing from the assumptions (i.e. gains or losses) are primarily accumulated in accrued pension liability and amortized over future periods if it exceeds the 10% corridor and, therefore, could affect Seaboard’s recognized pension expense in such future periods, as permitted under GAAP. Accordingly, accumulated gains or losses in excess of the 10% corridor are amortized over the average future service of active participants. See Note 9 to the consolidated financial statements for further discussion.

DERIVATIVE INFORMATION

Seaboard is exposed to various types of market risks in its day-to-day operations. Primary market risk exposures result from changing commodity prices, foreign currency exchange rates, interest rates and equity prices. Occasionally derivatives are used to manage all of these overall market risks; however, Seaboard does not perform the extensive record-keeping required to account for derivative transactions as hedges. Management believes it uses derivatives primarily as economic hedges, although they do not qualify as hedges for accounting purposes. Because these derivatives are not accounted for as hedges, fluctuations in the related prices could have a material impact on earnings in any given year. Seaboard also enters into speculative derivative transactions related to its market risks.

Changes in commodity prices affect the cost of necessary raw materials and other inventories, finished product sales and firm sales commitments. Seaboard uses various grain, oilseed and other commodity futures and options purchase contracts to manage certain risks of increasing prices of raw materials and firm sales commitments or anticipated sales contracts. Short sales contracts are then used to offset the open purchase derivatives when the related commodity inventory is purchased in advance of the derivative maturity, effectively offsetting the initial futures or option purchase contract. From time to time, hog futures are used to manage risks of increasing prices of live hogs acquired for processing, and hog futures are used to manage risks of fluctuating prices of pork product inventories and related future sales. Inventories that are

sensitive to changes in commodity prices, including carrying amounts at December 31, 2017 and 2016, are presented in Note 3 to the consolidated financial statements. Raw material requirements, finished product sales and firm sales commitments are also sensitive to changes in commodity prices.

Because changes in foreign currency exchange rates affect the cash paid or received on foreign currency denominated receivables and payables, Seaboard manages certain of these risks through the use of foreign currency exchange agreements. Because changes in interest rates affect the cash required to service variable-rate debt, Seaboard sometimes uses interest rate exchange agreements to manage risks of increasing interest rates. During 2010, Seaboard entered into three ten-year interest rate exchange agreements, which involved the exchange of fixed-rate and variable-rate interest payments over the life of the agreements without the exchange of the underlying notional amounts to mitigate the effects of fluctuations in interest rates on variable-rate debt. Seaboard paid a fixed rate and received a variable rate of interest on the three notional amounts of $25 million each. Seaboard terminated these agreements in December 2017. None of these interest rate exchange agreements qualified as hedges for accounting purposes and, accordingly, the changes in fair value of these agreements were recorded in miscellaneous, net in the consolidated statements of comprehensive income.

Equity price risk is the risk that Seaboard may incur losses due to adverse changes in the market prices of the equity securities it holds in its short-term investment portfolio. Market prices for equity securities are subject to fluctuation and may result from perceived changes in the underlying economic characteristics of the investee, the relative price of alternative investments and general market conditions. As of December 31, 2017 and 2016, the fair value of Seaboard’s marketable equity securities was approximately $1 billion and $700 million, respectively.

The following table presents the sensitivity of the fair value of Seaboard’s open net commodity future and option contracts, foreign currency exchange agreements and marketable equity securities to a hypothetical 10% change in market prices, and foreign exchange rates as of December 31, 2017 and December 31, 2016. For all open derivatives, the fair value of such positions is a summation of the fair values calculated for each item by valuing each net position at quoted market prices as of the applicable date.

The table below provides information about Seaboard’s non-trading financial instruments sensitive to changes in interest rates at December 31, 2017. For debt obligations, the table presents principal cash flows and related weighted average interest rates by expected maturity dates. Long-term variable debt included foreign subsidiary obligations payable in Argentine pesos of $13 million and $16 million at December 31, 2017 and 2016, respectively.

Non-trading financial instruments sensitive to changes in interest rates at December 31, 2016 consisted of variable rate long-term debt totaling $517 million with an average interest rate of 3.09%.

SEABOARD CORPORATION

Management’s Reports

Management’s Responsibility for Consolidated Financial Statements

The management of Seaboard Corporation and its consolidated subsidiaries (“Seaboard”) is responsible for the preparation of its consolidated financial statements and related information appearing in this report. Management believes that the consolidated financial statements fairly present Seaboard’s financial position and results of operations in conformity with U.S. generally accepted accounting principles, and necessarily includes amounts that are based on estimates and judgments which it believes are reasonable based on current circumstances with due consideration given to materiality.

Management relies on a system of internal controls over financial reporting that is designed to provide reasonable assurance that assets are safeguarded, transactions are executed in accordance with company policy and U.S. generally accepted accounting principles and are properly recorded, and accounting records are adequate for preparation of financial statements and other information and disclosures. The concept of reasonable assurance is based on recognition that the cost of a control system should not exceed the benefits expected to be derived, and such evaluations require estimates and judgments. The design and effectiveness of the system are monitored by a professional staff of internal auditors.

All internal control systems, no matter how well designed, have inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance, and is subject to lapses in judgment and breakdowns resulting from human failures. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The Board of Directors pursues its review of auditing internal controls and financial statements through its audit committee, composed entirely of independent directors. In the exercise of its responsibilities, the audit committee meets periodically with management, with the internal auditors and with the independent registered public accounting firm to review the scope and results of audits.

Seaboard Corporation:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Seaboard Corporation and subsidiaries (“the Company”) as of December 31, 2017 and 2016, the related consolidated statements of comprehensive income, changes in equity, and cash flows for each of the years in the three‑year period ended December 31, 2017, and the related notes (collectively, the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 21, 2018 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 1959.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
