Item 5.04. Temporary Suspension of Trading Under Registrant's Benefit Plans.

On November 21, 2007, we received a notice (the "Notice") required by Section 101(i)(2)(E) of the Employment Retirement Income Security Act of 1974, as amended, related to the spin-off of accounts of employees of our wholly owned subsidiary, Delaware Management Holdings, Inc., from the Lincoln National Corporation Employees' Savings and Profit Sharing 401(k) Plan (the "Lincoln Plan") into a new plan, the Delaware Management Holdings, Inc. Employees' Savings and 401(k) Plan (the "Delaware Plan") effective January 1, 2008. These participants constitute less than ten percent of the Lincoln Plan participants. The Notice describes a blackout period which will occur under the Lincoln Plan for participants in the Delaware Plan in connection with the separation of the Delaware Plan. The Notice is attached hereto as Exhibit 99.1 and is incorporated by reference herein. Shares of our common stock held in LNC common stock fund, a unitized fund investing exclusively in shares of LNC common stock, of the Lincoln Plan and, following the separation of the Delaware Plan, by participants in the Delaware Plan will be subject to the blackout period described in the Notice. The blackout period described in the Notice will not prohibit our directors and executive officers from engaging in transactions regarding shares of our common stock outside of the Lincoln and Delaware Plans. The blackout will impact one executive officer who will participate in the Delaware Plan. During the blackout period, this officer will not be able to direct any transactions with respect to the LNC common stock fund.
