Item 2.05 – Costs Associated with Exit or Disposal Activities.

On March 30, 2015, Campbell Soup Company (the “Company”) commenced a voluntary employee separation program (the “Program”) as part of its recently-announced initiatives to reduce costs and to streamline its organizational structure. The Program is available to certain U.S.-based salaried employees nearing retirement who meet the Program’s age, length-of-service and business unit/function criteria. Employees who elect the Program will receive enhanced separation benefits. The Program is expected to be substantially completed by the end of fiscal 2015. Executive officers and other members of senior management are not eligible for the Program.

The Company currently does not know which employees will elect to participate in the Program. Therefore, the Company is unable to estimate the costs of the Program, although the Company expects these costs to consist primarily of employee severance and benefits-related costs. The Company will provide an estimate of the amount or range of costs expected to be incurred when a good faith determination can be made.
