Item 5.03		Amendments to Articles of Incorporation or Bylaws; Changes in Fiscal Year.

On December 4, 2007, the Board of Directors of Advanced Energy Industries, Inc. (the “Company”) amended Section 34, 35 and 36 of Article VII of the Company’s Bylaws to clarify the authority to issue uncertificated shares of the Company’s stock and the procedures relating to the transfer of shares of the Company’s common stock. The ability to issue uncertificated shares allows the Company’s securities to be eligible for the direct registration system as required by Nasdaq Stock Market regulations effective January 1, 2008. The direct registration system, or “DRS”, allows an investor’s ownership to be recorded directly on the books of the issuer or the issuer’s transfer agent, without the need for the investor to hold a physical certificate.

The Amendment to the Company’s Bylaws is attached as Exhibit 3.1 to this report and is incorporated by reference.
