The following information is a Summary of Material Modifications/Notice of changes relating to certain investment options under the Lincoln National Corporation Agents' Deferred Compensation Plan ("Plan"). More information about each of the investment options offered under the Plan (except for the LNC Stock Fund) can be obtained by logging in to your account on Nolan's website at:, or call Nolan's Deferred Compensation Customer Service Line at 888 907-8633.

SSgA Target Retirement 2010 Fund/Target Retirement Income Fund:

Effective April 1, 2015, the SSgA Target Retirement 2010 Fund (the "2010 Fund") will merge into or become part of the SSgA Target Retirement Income Fund (the "Income Fund").  The Income Fund is designed for those participants who are in retirement and it does not evolve its mix of stocks and bonds.  It has the lowest exposure to stocks compared to other SSgA Target Retirement Funds.

The 2010 Fund was designed to evolve to reduce its exposure to stocks until its mix of investments matched the Income Fund (i.e., they eventually would have the same asset allocation).  Because the 2010 Fund now mirrors the Income Fund, the 2010 Fund is being merged into the Income Fund.

If you are invested in the 2010 Fund, your investments in that fund will move automatically into the Income Fund after the close of business on March 30, 2015.  Beginning April 1, 2015, you will no longer see the 2010 Fund in your account; instead you will see the Income Fund.

SSgA Target Retirement 2060 Fund:

Effective April 1, 2015, the new SSgA Target Retirement 2060 Fund (the "2060 Fund") will be offered under the Plan.  The 2060 Fund, designed for those participants whose retirement is over 40 years away, invests in a mix of stocks and bonds and will adjust its mix of investments automatically over time to stay appropriate with a participant's age.

The 2060 Fund will be the default fund for those participants who have not made an affirmative investment election under the Plan and for whom the Fund most closely matches the year such participant attains age 65.

You do not need to make any changes to your Plan account as a result of these changes. However, you may wish to review your current investment selections to ensure they are right for you.
