Prior to these actions, the company had maintained the Tenneco Automotive Inc. Supplemental Executive Compensation Plan ("SERP"), Key Executive Pension Plan ("KEPP") and Deferred Compensation Plan ("DC Plan"), each of which has been filed as an exhibit to the company's periodic reports under the Securities Exchange Act of 1934. The company amended the SERP, KEPP and DC Plan to "freeze" these plans with respect to participation, contributions and deferrals as of December 31, 2004. At the same time, the company adopted the Tenneco Automotive Inc. Supplemental Retirement Plan, Supplemental Pension Plan for Management and Incentive Deferral Plan. The company took these actions so that the participants under these plans could avoid negative tax implications that would have resulted from the passage of the American Jobs Creation Act of 2004 and its creation of Internal Revenue Code Section 409A. The new plans do not change the benefit levels that participants are entitled to receive. The Supplemental Retirement Plan provides retirement benefits with respect to certain employees that are equal to the retirement benefits lost under the company's pension plan for salaried employees as a result of the imposition of limitations included in the Internal Revenue Code of 1986. The Supplemental Pension Plan for Management provides further retirement benefits for a select group of key employees. The Incentive Deferral Plan provides directors and certain employees with the opportunity to defer compensation received by them from the company. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
