Part I ITEM 1. BUSINESS, continued DowDuPont Cost Synergy Program 2017 Restructuring Program Spin-off of Performance Chemicals Segment Information Principal Product Information Agriculture 4 The agriculture product line offers a broad portfolio of products and services that are specifically targeted to achieve gains in crop yields and productivity for the global production agriculture industry. The agriculture product line includes hybrid corn seed and soybean seed varieties, primarily under the Pioneer$^{®}$ brand name, as well as canola, sunflower, sorghum, wheat and rice seed, silage inoculants, weed, insect and disease control products, as well as agronomic software. Seed sales amounted to 27 percent, 15 percent, 34 percent and 29 percent of the company's total consolidated net sales for the year ended December 31, 2018, the period September 1 through December 31, 2017, the period January 1 through August 31, 2017, and the year ended December 31, 2016, respectively. Subsidiaries and affiliates of Historical DuPont conduct manufacturing, seed production and/or selling activities and some are distributors of products manufactured by the company. The following describes the company’s principal product lines including major brands and technologies: Effective with the Merger, Historical DuPont’s business activities are components of its parent company’s business operations. Historical DuPont’s business activities, including the assessment of performance and allocation of resources, are reviewed and managed by DowDuPont. Information used by the chief operating decision maker of Historical DuPont relates to the company in its entirety. Accordingly, there are no separate reportable business segments for Historical DuPont under Accounting Standards Codification ("ASC") Topic 280 “Segment Reporting” and Historical DuPont's business results are reported in this Form 10-K as a single operating segment. On July 1, 2015, Historical DuPont completed the separation of its Performance Chemicals segment through the spin-off of all of the issued and outstanding stock of The Chemours Company. In connection with the separation, the company and Chemours entered into a Separation Agreement and a Tax Matters Agreement as well as certain ancillary agreements. In accordance with generally accepted accounting principles in the U.S. ("GAAP"), the results of operations of its former Performance Chemicals segment are presented as discontinued operations and, as such, are included within (loss) income from discontinued operations after income taxes in the Consolidated Statements of Operations for all periods presented. Additional details regarding the separation and other related agreements can be found in Note 4 to the Consolidated Financial Statements. During the first quarter 2017, Historical DuPont committed to take actions to improve plant productivity and better position its product lines for productivity and growth before and after the anticipated closing of the Merger Transaction (the "2017 restructuring program"). In connection with these actions, the company incurred pre-tax charges of $313 million for the period January 1 through August 31, 2017 recognized in restructuring and asset related charges - net in the company's Consolidated Statements of Operations. The charge is comprised of $279 million of asset related charges and $34 million in severance and related benefit costs. These charges primarily relate to the second quarter closure of the safety and construction product line at the Cooper River manufacturing site located near Charleston, South Carolina. The asset related charges mainly consist of accelerated depreciation associated with the closure. The actions associated with this plan are substantially complete. The company anticipates including savings associated with these actions within the targeted cost synergies associated with the Merger Transaction. Additional details related to this plan can be found in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, on page 18 of this report and Note 6 to the Consolidated Financial Statements. In September and November 2017, DowDuPont and the company approved post-merger restructuring actions to achieve targeted cost synergies under the DowDuPont Cost Synergy Program (the “Synergy Program”), adopted by the DowDuPont Board of Directors. The Synergy Program is designed to integrate and optimize the organization following the Merger and in preparation for the Intended Business Separations. Based on all actions approved to date under the Synergy Program, Historical DuPont expects to record total pre-tax restructuring charges of $575 million to $675 million, comprised of approximately $370 million to $400 million of severance and related benefits costs; $80 million to $100 million of costs related to contract terminations; and $125 million to $175 million of asset related charges. The company anticipates including savings associated with these actions within DowDuPont's cost synergy commitment of $3.6 billion associated with the Merger Transaction. Additional details related to this plan can be found in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, on page 18 of this report and Note 6 to the Consolidated Financial Statements.
