Item 5.04 Temporary Suspension of Trading Under Registrant's Employee Benefit
Plans.
E. I. du Pont de Nemours and Company (the "Company") has decided to transition to new investment choices under the DuPont Savings and Investment Plan, the DuPont Retirement Savings Plan, the DuPont 401(k) and Profit Sharing Plan and the Thrift and Savings Plan for Employees of Sentinel Transportation, LLC (together, the "Plans"), which will require a blackout period during which eligible employees will be unable to enroll in the Plans and participants in the Plans will be temporarily unable to change their contribution rates, direct or diversify investments in their individual accounts, including accounts that hold the common stock of the Company, or to obtain a loan or distribution from the Plans. The blackout period will also apply to the DuPont Retirement Savings Restoration Plan and the DuPont Salary Deferral and Savings Restoration Plan to the extent the aforementioned rights normally are available under those plans.
On December 5, 2007, the Company received notice of the blackout period pursuant to Section 101(i)(2)(E) of the Employee Retirement Income Security Act of 1974 with respect to the Plans. On December 11, 2007, the Company sent a Notice of Blackout Period Memorandum (the "Memorandum") to its directors and executive officers informing them that a blackout period is expected to be in effect beginning at 3 p.m. ET on January 25, 2008 and ending at 12 a.m. ET on February 4, 2008. However, the blackout period may be extended due to events beyond the Company's control that may arise as part of the transition, in which case notice will be given to the directors and executive officers as soon as reasonably practicable.
The Memorandum was provided to the Company's directors and executive officers pursuant to the requirements of Section 306 of the Sarbanes-Oxley Act of 2002 and Rule 104 of the Securities and Exchange Commission's Regulation BTR.
During the blackout period and for a period of two years after the ending date of the blackout period, holders of the Company's common stock and other interested parties may obtain, without charge, the actual beginning and ending dates of the blackout period by sending a written request to James C. Borel, Vice President, E. I. du Pont de Nemours and Company, 1007 Market Street, Wilmington, Delaware 19898 or by calling (302) 774-1000.
A copy of the Memorandum is attached as Exhibit 99.1 to this current Report on Form 8-K and incorporated herein by reference. Item 9.01 Financial Statements and Exhibits.
