Dear Preferred Shareholder:

The annual meeting of shareholders of Advent Claymore Convertible Securities and Income Fund (“AVK”) and Advent Claymore Convertible Securities and Income Fund II (“AGC” and together with AVK, the “Trusts”) on October 24, 2012 has been adjourned to Wednesday, November 14, 2012 at 10:00 a.m. Eastern time with respect to the election of trustees by the holders of preferred shares voting as a separate class to provide shareholders who have not yet cast their proxy vote with additional time to do so.  The reconvened annual meeting will be held at the offices of the Trusts’ counsel, Skadden, Arps, Slate, Meagher & Flom LLP, 4 Times Square, New York, New York 10036

Our records indicate that you are a record date holder of preferred shares and your vote has not yet been received. It is critical that your proxy vote is received before the reconvened annual meeting. Additional solicitation efforts are costly and could delay the important business of the Trusts.

Enclosed you will find another copy of your proxy ballot(s) which lists the proposals to be voted on.  If you need another copy of the Trusts’ proxy statement or have any proxy-related questions, please contact the Trusts at (866) 274-2227.

I thank you in advance for your help with this urgent matter.

Sincerely
