Proposed Reorganization. The Board of Trustees of Fidelity Income Fund has unanimously approved an Agreement and Plan of Reorganization ("Agreement") between Fidelity Managed Retirement 2035 Fund℠ and Fidelity Freedom® Blend 2030 Fund pursuant to which Fidelity Managed Retirement 2035 Fund℠ would be reorganized on a tax-free basis with and into Fidelity Freedom® Blend 2030 Fund.
