GUGGENHEIM BULLETSHARES 2017 CORPORATE BOND ETF (BSCH) Exchange: NYSE ARCA

DELISTED - The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the 2017 Index. The 2017 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 99 investment grade corporate bonds with effective maturities in the year 2017. The 2017 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the year 2017. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may "call" or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the 2017 Index, and thus of the Fund, is 0 to 0.25 years. Accretive is affiliated with Guggenheim Funds Investment Advisors, LLC, the Fund's investment adviser (the "Investment Adviser"), and Guggenheim Funds Distributors, LLC, the Fund's distributor (the "Distributor").The Fund has a designated year of maturity of 2017 and will terminate on or about December 31, 2017. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the 2017 Index. Under normal circumstances, the Fund will invest at least 80% of its net assets in corporate bonds. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the 2017 Index. As the Fund is in the final year of its operations, the bonds in the 2017 Index are maturing, and the Fund’s portfolio is in the process of transitioning to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2017 without requiring additional approval by the Board of Trustees (the “Board”) of Claymore Exchange-Traded Fund Trust (the "Trust") or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated. The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Investment Adviser uses quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Index components on the performance of the Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Index with the same weights as the Index. There may also be instances when the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index, which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Index. In addition, from time to time, securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index pursuant to scheduled reconstitutions and rebalancings of the Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Index is so concentrated. As of May 31, 2017, the financial sector represented a substantial portion of the Index.Guggenheim Investments announced on September 28, 2017, that it has entered into a definitive agreement to sell its exchange-traded funds business to Invesco Ltd. (“Invesco”), a leading global investment management company. As a result, the Investment Adviser expects to propose to the Board that it approve a reorganization of the Fund into a newly organized exchange-traded fund advised by an affiliate of Invesco. If approved by the Board, the reorganization of the Fund would be submitted to the shareholders of the Fund for their approval.
