EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you may pay when purchasing or selling Shares.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Claymore Exchange-Traded Fund Trust 1 | Guggenheim Enhanced Short Duration Bond ETF | USD ($)	29	145	271	641

The above Example reflects applicable contractual expense reimbursement arrangements for the duration of the arrangements only.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund will invest at least 80% of its net assets in fixed income securities and in exchange-traded funds ("ETFs") and closed-end funds that invest substantially all of their assets in fixed income securities. The Fund uses a low duration strategy to seek to outperform the Barclays Capital 1-3 Month U.S. Treasury Bill Index (the “Benchmark”) in addition to providing returns in excess of those available in U.S. Treasury bills, government repurchase agreements, and money market funds, while seeking to provide preservation of capital and daily liquidity. The Fund is not a money market fund and thus does not seek to maintain a stable net asset value ("NAV") of $1.00 per Share.

The Fund expects, under normal circumstances, to hold a diversified portfolio of fixed income instruments of varying maturities, but that have an average duration of less than one year. Duration is a measure of the price volatility of a debt instrument as a result of changes in interest rates, based on the weighted average timing of the instrument’s expected principal and interest payments. Duration differs from maturity in that it considers, among other characteristics, an instrument’s yield, coupon payments, principal payments and call features in addition to the amount of time until the instrument matures. As the value of an instrument changes over time, so will its duration.

The Fund may invest, without limitation, in short-term instruments such as commercial paper and/or repurchase agreements. Commercial paper includes variable amount master demand notes and asset-backed commercial paper. Commercial paper normally represents short-term unsecured promissory notes issued by banks or bank holding companies, corporations, finance companies and other issuers. Repurchase agreements are fixed-income securities in the form of agreements backed by collateral. These agreements, which may be viewed as a type of secured lending by the Fund, typically involve the acquisition by the Fund of securities from the selling institution (such as a bank or a broker-dealer), coupled with the agreement that the selling institution will repurchase the underlying securities at a specified price and at a fixed time in the future (or on demand). The Fund may accept a wide variety of underlying securities as collateral for the repurchase agreements entered into by the Fund. Such collateral may include U.S. government securities, corporate obligations, equity securities, municipal debt securities, mortgage-backed securities and convertible securities. Any such securities serving as collateral are marked-to-market daily in order to maintain full collateralization (typically purchase price plus accrued interest).

The Fund primarily invests in U.S. dollar-denominated investment grade debt securities, including U.S. Treasury securities and corporate bonds, rated Baa3 or higher by Moody’s Investors Service, Inc. (“Moody’s”), or equivalently rated by Standard & Poor’s Rating Group (“S&P”), Fitch Investor Services (“Fitch”), or any other nationally recognized statistical rating organization ("NRSRO"), or, if unrated, determined by the Investment Adviser to be of comparable quality. The Fund may invest no more than 10% of its assets in high yield securities (which also may be known as “junk bonds”), which are debt securities that are rated below investment grade by NRSROs, or are unrated securities that the Investment Adviser believes are of comparable quality. The Fund may invest in securities that are offered pursuant to Rule 144A (“Rule 144A”) under the Securities Act of 1933, as amended (“Securities Act”). Rule 144A securities are securities which, while privately placed, are eligible for purchase and resale pursuant to Rule 144A. This rule permits certain qualified institutional buyers, such as the Fund, to trade in privately placed securities even though such securities are not registered under the Securities Act. The Investment Adviser will evaluate the liquidity of Rule 144A securities prior to investing in such securities and monitor their liquidity thereafter. The Fund will not invest in securities that are in default at the time of investment. If a security defaults subsequent to purchase by the Fund, the Investment Adviser will determine in its discretion whether to hold or dispose of such security.

The Fund may invest in bank obligations, which include certificates of deposit, commercial paper, unsecured bank promissory notes, bankers’ acceptances, time deposits and other debt obligations. The Fund may invest in obligations issued or backed by U.S. banks when a bank has more than $1 billion in total assets at the time of purchase or is a branch or subsidiary of such a bank. In addition, the Fund may invest in U.S. dollar-denominated obligations issued or guaranteed by foreign banks that have more than $1 billion in total assets at the time of purchase, U.S. branches of such foreign banks (Yankee obligations), foreign branches of such foreign banks and foreign branches of U.S. banks having more than $1 billion in total assets at the time of purchase. Bank obligations may be general obligations of the parent bank or may be limited to the issuing branch by the terms of the specific obligation or by U.S. government regulation.

The Fund may invest, without limitation, in U.S. dollar-denominated debt securities of foreign issuers, including emerging market issuers. The Fund may also invest up to 10% of its assets in sovereign and corporate debt securities denominated in foreign currencies. The Investment Adviser may attempt to reduce foreign currency exchange rate risk by entering into contracts with banks, brokers or dealers to purchase or sell securities or foreign currencies at a future date (“forward contracts”).The Fund may also invest up to 25% of its assets in municipal securities. The Fund will not invest in options contracts, futures contracts or swap agreements.

The Fund currently may invest up to 20% of its assets in mortgage-backed securities (“MBS”) or in other asset-backed securities ("ABS"). This limitation does not apply to securities issued or guaranteed by federal agencies and/or U.S. government sponsored instrumentalities, such as the Government National Mortgage Administration (“GNMA”), the Federal Housing Administration (“FHA”), the Federal National Mortgage Association (“FNMA”) and the Federal Home Loan Mortgage Corporation (“FHLMC”). In addition to securities issued or guaranteed by such agencies or instrumentalities, the Fund may invest in MBS or other ABS issued or guaranteed by private issuers. The MBS in which the Fund may invest may also include residential mortgage-backed securities (“RMBS”), collateralized mortgage obligations (“CMOs”) and commercial mortgage-backed securities (“CMBS”). The ABS in which the Fund may invest include collateralized debt obligations (“CDOs”). CDOs include collateralized bond obligations (“CBOs”), collateralized loan obligations (“CLOs”) and other similarly structured securities. A CBO is a trust which is backed by a diversified pool of high risk, below investment grade fixed income securities. A CLO is a trust typically collateralized by a pool of loans, which may include domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans.

The Fund may obtain exposure to the securities in which it normally invests by engaging in various investment techniques, including forward purchase agreements, mortgage dollar rolls and “TBA” mortgage trading. A mortgage dollar roll involves the sale of a MBS by the Fund and its agreement to repurchase the instrument (or one which is substantially similar) at a specified time and price. Most transactions in fixed-rate mortgage pass-through securities occur through standardized contracts for future delivery in which the exact mortgage pools to be delivered are not specified until a few days prior to settlements (a “TBA” transaction). The Fund may enter into such contracts on a regular basis. The Fund, pending settlement of such contracts, will invest its assets in high-quality, liquid short-term instruments, including shares of money market funds. The Fund will assume its pro rata share of the fees and expenses of any money market fund (or other investment company) that it may invest in, in addition to the Fund’s own fees and expenses. The Fund may also acquire interests in mortgage pools through means other than such standardized contracts for future delivery. The Fund also may invest directly in ETFs and other investment companies that provide exposure to fixed income securities similar to those securities in which the Fund may invest in directly.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Active Management Risk—The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, causing the Fund to fail to meet its investment objective or underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management, also called “high turnover,” may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

Asset-Backed Securities Risk—Investors in asset-backed securities, including mortgage-backed securities and structured finance investments, generally receive payments that are part interest and part return of principal. These payments may vary based on the rate at which the underlying borrowers pay off their loans. Some asset-backed securities, including mortgage-backed securities, may have structures that make their reaction to interest rates and other factors difficult to predict, causing their prices to be volatile. These instruments are particularly subject to interest rate, credit and liquidity and valuation risks.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Bank Obligations Risk—The Fund’s investments in bank obligations are subject to risks generally applicable to debt securities, but also expose the Fund to risks associated with adverse developments in or related to the banking industry. The activities of U.S. and most foreign banks are subject to comprehensive regulations, which, in the case of U.S. regulations, have undergone substantial changes in the past decade. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operations and profitability of domestic and foreign banks.

Collateralized Loan Obligations and Collateralized Debt Obligations Risk—Collateralized loan obligations (“CLOs”) bear many of the same risks as other forms of asset-backed securities, including interest rate risk, credit risk and default risk. As they are backed by pools of loans, CLOs also bear similar risks to investing in loans directly. CLOs issue classes or “tranches” that vary in risk and yield. CLOs may experience substantial losses attributable to loan defaults. Losses caused by defaults on underlying assets are borne first by the holders of subordinate tranches. The Fund’ss investment in CLOs may decrease in market value when the CLO experiences loan defaults or credit impairment, the disappearance of a subordinate tranche, or market anticipation of defaults and investor aversion to CLO securities as a class.

Collateralized debt obligations (“CDOs”) are structured similarly to CLOs and bear the same risks as CLOs including interest rate risk, credit risk and default risk. CDOs are subject to additional risks because they are backed by pools of assets other than loans including securities (such as other asset-backed securities), synthetic instruments or bonds and may be highly leveraged. Like CLOs, losses incurred by a CDO are borne first by holders of subordinate tranches. Accordingly, the risks of CDOs depend largely on the type of underlying collateral and the tranche of CDOs in which the Fund invests. For example, CDOs that obtain their exposure through synthetic investments entail the risks associated with derivative instruments.

Commercial Paper Risk—The value of the Fund’s investment in commercial paper, which is an unsecured promissory note that generally has a maturity date between one and 270 days and is issued by a U.S. or foreign entity, is susceptible to changes in the issuer’s financial condition or credit quality. Investments in commercial paper are usually discounted from their value at maturity. Commercial paper can be fixed-rate or variable rate and can be adversely affected by changes in interest rates.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Currency Risk—Indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, which would cause a decline in the U.S. value of the holdings of the Fund. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the imposition of currency controls or other political, economic and tax developments in the U.S. or abroad. The Fund’s foreign currency hedging transactions and techniques may not be effective and, in certain cases, may adversely affect the Fund. In addition, the Fund’s ability to engage in these transactions and techniques may be limited under certain circumstances.

Dollar Roll Transaction Risk—The Fund may enter into dollar roll transactions, in which the Fund sells a mortgage-backed or other security for settlement on one date and buys back a substantially similar security for settlement at a later date. Dollar rolls involve a risk of loss if the market value of the securities that the Fund is committed to buy declines below the price of the securities the Fund has sold.

Emerging Markets Risk—Investments in or exposure to emerging markets securities are generally subject to a greater level of those risks associated with investing in foreign securities, as emerging markets are considered less developed than developing countries. Furthermore, investments in emerging market countries are generally subject to additional risks, including trading on smaller markets, having lower volumes of trading, and being subject to lower levels of government regulation and less extensive accounting, financial and other reporting requirements.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements.  The Fund may be adversely affected by events or developments negatively impacting the financial sector.

Foreign Securities Risk—The Fund may invest in U.S. and non-U.S. dollar-denominated bonds of foreign corporations, governments, agencies and supra-national agencies. Foreign securities carry unique or additional risks when compared to U.S. securities, including currency fluctuations, adverse political and economic developments, unreliable or untimely information, less liquidity, limited legal recourse and higher transactional costs.

High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as "junk bonds") may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Investment in Investment Companies Risk—Investing in other investment other investment companies, including ETFs and closed-end funds, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying investment companies’ expenses, which will reduce the Fund’s performance, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of substantial premiums above the value of such companies' portfolio securities or NAVs. In addition, investments by the Fund in another ETF are subject to, among other risks, the risk that the ETF's shares may trade at a discount or premium relative to the NAV of the shares and the listing exchange may halt trading of the ETF's shares.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value, causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk-The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets. The Fund is not a money market fund and thus does not seek to maintain a stable NAV of $1.00 per Share.

Municipal Securities Risk—Municipal securities may be subject to credit, interest, prepayment, liquidity and valuation risks. In addition, municipal securities can be affected by unfavorable legislative or political developments and adverse changes in the economic and fiscal conditions of state and municipal issuers or the federal government in case it provides financial support to such issuers. Certain sectors of the municipal bond market have special risks that can affect them more significantly than the market as a whole. Because many municipal instruments are issued to finance similar projects, conditions in these industries can significantly affect the overall municipal market. Municipal securities that are insured by an insurer may be adversely affected by developments relevant to that particular insurer, or more general developments relevant to the market as a whole. Municipal securities can be difficult to value and be less liquid than other investments, which may affect the Fund’s performance.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Repurchase Agreements Risk—In the event of the insolvency of the counterparty to a repurchase agreement, recovery of the repurchase price owed to the Fund may be delayed.

Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

To-Be-Announced (“TBA”) Transactions Risk—The Fund may enter into TBA transactions to purchase or sell mortgage-backed securities for a fixed price at a future date. TBA purchase commitments involve a risk of loss if the value of the securities to be purchased declines prior to settlement date or if the counterparty may not deliver the securities as promised. Selling a TBA involves a risk of loss if the value of the securities to be sold goes up prior to settlement date.

U.S. Government Securities Risk—U.S. government securities may or may not be backed by the full faith and credit of the U.S. government. U.S. government securities are subject to the risks associated with fixed-income and debt securities, particularly interest rate risk and credit risk.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 85% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 2016 Index. The 2016 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 73 investment grade corporate bonds with effective maturities in the year 2016. The 2016 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 2016. 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 2016 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 2016 and will terminate on or about December 31, 2016. 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 2016 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 2016 Index. As the Fund is in the final year of its operations, the bonds in the 2016 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, 2016 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 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, 2016, the financial sector represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—As the Fund is in the final year of its operations, the bonds held by the Fund are maturing and the Fund’s portfolio is transitioning to cash and cash equivalents. Accordingly, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Guggenheim BulletShares 2017 Corporate Bond ETF (BSCH)

INVESTMENT OBJECTIVE

The Guggenheim BulletShares 2017 Corporate Bond ETF (the "Fund") seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares® USD Corporate Bond 2017 Index (the “2017 Index” or the “Index”).

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you may pay when purchasing or selling Shares.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 11% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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, 2016, approximately 326 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 0.5 to 1 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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 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, 2016, the financial sector represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Non-Diversification Risk—The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Non-Diversification Risk—The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Claymore Exchange-Traded Fund Trust 1 | Guggenheim BulletShares 2019 Corporate Bond ETF

Guggenheim BulletShares 2019 Corporate Bond ETF (BSCJ)

INVESTMENT OBJECTIVE

The Guggenheim BulletShares 2019 Corporate Bond ETF (the "Fund") seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares® USD Corporate Bond 2019 Index (the “2019 Index” or the “Index”).

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you may pay when purchasing or selling Shares.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 11% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 2019 Index. The 2019 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 339 investment grade corporate bonds with effective maturities in the year 2019. The 2019 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 2019. 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 2019 Index, and thus of the Fund, is 1 to 3 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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 2019 and will terminate on or about December 31, 2019. 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 2019 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 2019 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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, 2019 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 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, 2016, the financial and consumer staples sectors each represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Consumer Staples Sector Risk—Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a derivatives transaction or other transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance.

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, 2016, the financial and consumer staples sectors each represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Consumer Staples Sector Risk—Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Non-Diversification Risk—The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Claymore Exchange-Traded Fund Trust 1 | Guggenheim BulletShares 2021 Corporate Bond ETF

Guggenheim BulletShares 2021 Corporate Bond ETF (BSCL)

INVESTMENT OBJECTIVE

The Guggenheim BulletShares 2021 Corporate Bond ETF (the "Fund") seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares® USD Corporate Bond 2021 Index (the “2021 Index” or the “Index”).

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you may pay when purchasing or selling Shares.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 6% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 2021 Index. The 2021 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 287 investment grade corporate bonds with effective maturities in the year 2021. The 2021 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 2021. 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 2021 Index, and thus of the Fund, is 3 to 5 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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 2021 and will terminate on or about December 31, 2021. 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 2021 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 2021 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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, 2021 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 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, 2016, the financial sector represented a substantial portion of the Index.

In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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, 2022 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 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, 2015, the financial and consumer staples sectors each represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Consumer Staples Sector Risk—Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Non-Diversification Risk—The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Claymore Exchange-Traded Fund Trust 1 | Guggenheim BulletShares 2023 Corporate Bond ETF

Guggenheim BulletShares 2023 Corporate Bond ETF (BSCN)

INVESTMENT OBJECTIVE

The Guggenheim BulletShares 2023 Corporate Bond ETF (the "Fund") seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares® USD Corporate Bond 2023 Index (the “2023 Index” or the “Index”).

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you may pay when purchasing or selling Shares.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Claymore Exchange-Traded Fund Trust 1 | Guggenheim BulletShares 2023 Corporate Bond ETF | USD ($)	25	132	249	592

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 2023 Index. The 2023 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 210 investment grade corporate bonds with effective maturities in the year 2023. The 2023 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 2023. 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 2023 Index, and thus of the Fund, is 5 to 7 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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 2023 and will terminate on or about December 31, 2023. 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 2023 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 2023 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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, 2023 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 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, 2016, the financial and consumer staples sectors each represented a substantial portion of the Index.

These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

The 2024 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 197 investment grade corporate bonds with effective maturities in the year 2024. The 2024 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 2024. 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 2024 Index, and thus of the Fund, is 6 to 8 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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 2024 and will terminate on or about December 31, 2024. 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 2024 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 2024 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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, 2024 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 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, 2016, the financial sector represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Non-Diversification Risk—The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

INVESTMENT OBJECTIVE

The Guggenheim BulletShares 2025 Corporate Bond ETF (the "Fund") seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares® USD Corporate Bond 2025 Index (the “2025 Index” or the “Index”).

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 3% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Consumer Staples Sector Risk—Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 41% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 High Yield 2016 Index. The High Yield 2016 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 25 high yield corporate bonds (which also may be known as "junk bonds") with effective maturities in the year 2016. The High Yield 2016 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield corporate bonds with effective maturities in the year 2016. 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 High Yield 2016 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 2016 and will terminate on or about December 31, 2016. 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 Index. Under normal circumstances, the Fund will invest at least 80% of its net assets in high yield securities, which are debt securities that are rated below investment grade by nationally recognized statistical rating organizations, or are unrated securities that the Investment Adviser believes are of comparable quality. 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 Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. As the Fund is in the final year of its operations, the bonds in the High Yield 2016 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, 2016 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 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, 2016, no sector represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—As the Fund is in the final year of its operations, the bonds held by the Fund are maturing and the Fund’s portfolio is transitioning to cash and cash equivalents. Accordingly, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as "junk bonds") may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Guggenheim BulletShares 2017 High Yield Corporate Bond ETF (BSJH)

INVESTMENT OBJECTIVE

The Guggenheim BulletShares 2017 High Yield Corporate Bond ETF (the "Fund") seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares® USD High Yield Corporate Bond 2017 Index (the “High Yield 2017 Index” or the “Index”).

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	Claymore Exchange-Traded Fund Trust 1 Guggenheim BulletShares 2017 High Yield Corporate Bond ETF
Management Fees (as a percentage of Assets)	0.42%
Other Expenses (as a percentage of Assets):	0.01%
Net Expenses (as a percentage of Assets)	0.43%

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you may pay when purchasing or selling Shares.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Claymore Exchange-Traded Fund Trust 1 | Guggenheim BulletShares 2017 High Yield Corporate Bond ETF | USD ($)	44	192	354	823

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 24% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 High Yield 2017 Index. The High Yield 2017 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 118 high yield corporate bonds (which also may be known as "junk bonds") with effective maturities in the year 2017. The High Yield 2017 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield 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 High Yield 2017 Index, and thus of the Fund, is 0.5 to 1 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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 Index. Under normal circumstances, the Fund will invest at least 80% of its net assets in high yield securities, which are debt securities that are rated below investment grade by nationally recognized statistical rating organizations, or are unrated securities that the Investment Adviser believes are of comparable quality. 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 Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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 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, 2016, the financial sector represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as "junk bonds") may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility.

Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Non-Diversification Risk—The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

The Guggenheim BulletShares 2018 High Yield Corporate Bond ETF (the "Fund") seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares® USD High Yield Corporate Bond 2018 Index (the “High Yield 2018 Index” or the “Index”).

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	Claymore Exchange-Traded Fund Trust 1 Guggenheim BulletShares 2018 High Yield Corporate Bond ETF
Management Fees (as a percentage of Assets)	0.42%
Other Expenses (as a percentage of Assets):	0.01%
Net Expenses (as a percentage of Assets)	0.43%

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you may pay when purchasing or selling Shares.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 High Yield 2018 Index. The High Yield 2018 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 137 high yield corporate bonds (which also may be known as "junk bonds") with effective maturities in the year 2018. The High Yield 2018 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield corporate bonds with effective maturities in the year 2018. 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 High Yield 2018 Index, and thus of the Fund, is 0.5 to 2 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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 2018 and will terminate on or about December 31, 2018. 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 Index. Under normal circumstances, the Fund will invest at least 80% of its net assets in high yield securities, which are debt securities that are rated below investment grade by nationally recognized statistical rating organizations, or are unrated securities that the Investment Adviser believes are of comparable quality. 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 Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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, 2018 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 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, 2016, the financial and consumer staples sectors each represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Consumer Staples Sector Risk—Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as "junk bonds") may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Non-Diversification Risk—The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

INVESTMENT OBJECTIVE

The Guggenheim BulletShares 2019 High Yield Corporate Bond ETF (the "Fund") seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares® USD High Yield Corporate Bond 2019 Index (the “High Yield 2019 Index” or the “Index”).

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you may pay when purchasing or selling Shares.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 High Yield 2019 Index. The High Yield 2019 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 166 high yield corporate bonds (which also may be known as "junk bonds") with effective maturities in the year 2019. The High Yield 2019 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield corporate bonds with effective maturities in the year 2019. 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 High Yield 2019 Index, and thus of the Fund, is 1 to 3 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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 2019 and will terminate on or about December 31, 2019. 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 Index. Under normal circumstances, the Fund will invest at least 80% of its net assets in high yield securities, which are debt securities that are rated below investment grade by nationally recognized statistical rating organizations, or are unrated securities that the Investment Adviser believes are of comparable quality. 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 Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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, 2019 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 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, 2016, the telecommunications sector represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as "junk bonds") may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk—The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

INVESTMENT OBJECTIVE

The Guggenheim BulletShares 2020 High Yield Corporate Bond ETF (the "Fund") seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares® USD High Yield Corporate Bond 2020 Index (the “High Yield 2020 Index” or the “Index”).

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you may pay when purchasing or selling Shares.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 13% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 High Yield 2020 Index. The High Yield 2020 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 199 high yield corporate bonds (which also may be known as "junk bonds") with effective maturities in the year 2020. The High Yield 2020 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield corporate bonds with effective maturities in the year 2020. 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 High Yield 2020 Index, and thus of the Fund, is 1 to 4 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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 2020 and will terminate on or about December 31, 2020. 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 Index. Under normal circumstances, the Fund will invest at least 80% of its net assets in high yield securities, which are debt securities that are rated below investment grade by nationally recognized statistical rating organizations, or are unrated securities that the Investment Adviser believes are of comparable quality. 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 Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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, 2020 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 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, 2016, the telecommunications and consumer staples sectors each represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Consumer Staples Sector Risk—Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as "junk bonds") may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Non-Diversification Risk—The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk—The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 15% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 High Yield 2021 Index. The High Yield 2021 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 203 high yield corporate bonds (which also may be known as "junk bonds") with effective maturities in the year 2021. The High Yield 2021 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield corporate bonds with effective maturities in the year 2021. 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 High Yield 2021 Index, and thus of the Fund, is 2 to 5 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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 2021 and will terminate on or about December 31, 2021. 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 Index. Under normal circumstances, the Fund will invest at least 80% of its net assets in high yield securities, which are debt securities that are rated below investment grade by nationally recognized statistical rating organizations, or are unrated securities that the Investment Adviser believes are of comparable quality. 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 Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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, 2021 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 objective if practicable.

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, 2016, the telecommunications, consumer staples and consumer discretionary sectors each represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Consumer Discretionary Sector Risk—The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers' disposable income, consumer preferences, social trends and marketing campaigns. The Fund may be adversely affected by events or developments negatively impacting the consumer discretionary sector or issuers within the consumer discretionary sector.

Consumer Staples Sector Risk—Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as "junk bonds") may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Non-Diversification Risk—The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk—The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

Guggenheim BulletShares 2022 High Yield Corporate Bond ETF (BSJM)

INVESTMENT OBJECTIVE

The Guggenheim BulletShares 2022 High Yield Corporate Bond ETF (the "Fund") seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares® USD High Yield Corporate Bond 2022 Index (the “High Yield 2022 Index” or the “Index”).

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you may pay when purchasing or selling Shares.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 11% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 High Yield 2022 Index. The High Yield 2022 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2016, approximately 174 high yield corporate bonds (which also may be known as "junk bonds") with effective maturities in the year 2022. The High Yield 2022 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield corporate bonds with effective maturities in the year 2022. 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 High Yield 2022 Index, and thus of the Fund, is 3 to 6 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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 2022 and will terminate on or about December 31, 2022. 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 Index. Under normal circumstances, the Fund will invest at least 80% of its net assets in high yield securities, which are debt securities that are rated below investment grade by nationally recognized statistical rating organizations, or are unrated securities that the Investment Adviser believes are of comparable quality. 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 Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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, 2022 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 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, 2016, the telecommunications and consumer staples sectors each represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Consumer Staples Sector Risk—Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as "junk bonds") may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Non-Diversification Risk—The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk—The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 3% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 High Yield 2023 Index. The High Yield 2023 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of September 30, 2016, approximately 120 high yield corporate bonds (which also may be known as "junk bonds") with effective maturities in the year 2023. The High Yield 2023 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield corporate bonds with effective maturities in the year 2023. 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 High Yield 2023 Index, and thus of the Fund, is 4 to 7 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund's expected duration will become shorter. 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 2023 and will terminate on or about December 31, 2023. 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 Index. Under normal circumstances, the Fund will invest at least 80% of its net assets in high yield securities, which are debt securities that are rated below investment grade by nationally recognized statistical rating organizations, or are unrated securities that the Investment Adviser believes are of comparable quality. 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 Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition 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, 2023 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 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, 2016, the telecommunications, consumer staples and consumer discretionary sectors each represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Consumer Discretionary Sector Risk—The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers' disposable income, consumer preferences, social trends and marketing campaigns. The Fund may be adversely affected by events or developments negatively impacting the consumer discretionary sector or issuers within the consumer discretionary sector.

Consumer Staples Sector Risk—Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument.

Declining Yield Risk—During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk—During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk—The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk—The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as "junk bonds") may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk—The Fund's income may decline during period of falling interest rates or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund's shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk—Investments in fixed-income securities are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s securities and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment. Fixed-income securities with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Adviser for purposes of the Fund’s net asset value ("NAV"), causing the Fund to be less liquid and unable to realize what the Investment Adviser believes should be the price of the investment.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Non-Diversification Risk—The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Prepayment Risk—Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions—In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk—The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

PERFORMANCE INFORMATION

As of the date of this Prospectus, the Fund has not yet completed a full calendar year of investment operations. When the Fund has completed a full calendar year of investment operations, this section will include charts that show annual total returns, highest and lowest quarterly returns and average annual total returns (before and after taxes) compared to the Index and a broad measure of market performance.

Claymore Exchange-Traded Fund Trust 1 | Guggenheim S&P Global Dividend Opportunities Index ETF

Guggenheim S&P Global Dividend Opportunities Index ETF (LVL)

INVESTMENT OBJECTIVE

The Guggenheim S&P Global Dividend Opportunities Index ETF (the "Fund") seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the S&P Global Dividend Opportunities Index (the “Dividend Opportunities Index” or the “Index”).

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	Claymore Exchange-Traded Fund Trust 1 Guggenheim S&P Global Dividend Opportunities Index ETF
Management Fees (as a percentage of Assets)	0.50%
Other Expenses (as a percentage of Assets):	0.27%
Expenses (as a percentage of Assets)	0.77%
Fee Waiver or Reimbursement	0.13%
Net Expenses (as a percentage of Assets)	0.64%

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example does not take into account brokerage commissions that you may pay when purchasing or selling Shares.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Claymore Exchange-Traded Fund Trust 1 | Guggenheim S&P Global Dividend Opportunities Index ETF | USD ($)	65	259	499	1,188

The above Example reflects applicable contractual expense reimbursement arrangements for the current duration of the arrangements only.

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 85% of the average value of its portfolio. 

PRINCIPAL INVESTMENT STRATEGIES

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 Dividend Opportunities Index. As of August 31, 2016, the Dividend Opportunities Index consisted of 100 common stocks and sponsored and unsponsored American depositary receipts (“ADRs”) (which may include other investment companies, including business development companies ("BDCs")) that offer high dividend yields chosen from a universe consisting of the stocks listed on the exchanges of those countries included in the S&P Global Broad Market Index (BMI). As of August 31, 2016, the countries in the Dividend Opportunities Index that allow for free in-kind transfer of shares were Australia, Canada, the Czech Republic, Finland, France, Germany, Hong Kong, Italy, Japan, Mexico, the Netherlands, New Zealand, Norway, Portugal, South Africa, Spain, Sweden, Switzerland, Turkey, the United Kingdom and the United States. Potential Index constituents include common stocks and ADRs with market capitalizations greater than $1.0 billion at the time of reconstitution, which for ADRs is determined based on an evaluation of the underlying security, and includes securities of mid- and large-capitalization companies, as defined by Standard & Poor’s, a division of The McGraw-Hill Companies, Inc., the Fund’s index provider (“S&P” or the “Index Provider”). The Fund will invest at least 90% of its total assets in common stocks and ADRs that comprise the Index and depositary receipts and shares representing common stocks that comprise the Index (or underlying securities representing ADRs that comprise the Index.) 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 Index. The Board of Trustees (the “Board”) of Claymore Exchange-Traded Fund Trust (the "Trust") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by the ADRs comprising the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing more liquidity than the ADR; (b) when an ADR is trading at a significantly different price than its underlying security; or (c) the timing of trade execution is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding ADR is traded.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. 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 included in the Index, (ii) restrictions or requirements in local markets possibly rendering it infeasible or inefficient for the Fund to purchase or sell a security in the Index or (iii) 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, 2016, the energy, financial and utilities sectors each represented a substantial portion of the Index.

PRINCIPAL RISKS

Investors should consider the principal risks associated with investing in the Fund, which are summarized below. The value of an investment in the Fund will fluctuate and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class Risk—The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk—If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Depositary Receipt Risk—The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Fund’s portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Fund’s portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.

Dividend-Paying Stock Risk—As a category, dividend-paying stocks may underperform non-dividend paying stocks (and the stock market as a whole) over any period of time. In addition, issuers of dividend-paying stocks may have discretion to defer or stop paying dividends for a stated period of time. If the dividend-paying stocks held by the Fund reduce or stop paying dividends, the Fund’s ability to generate income may be adversely affected.

Emerging Markets Risk—Investments in or exposure to emerging markets securities are generally subject to a greater level of those risks associated with investing in foreign securities, as emerging markets are considered less developed than developing countries. Furthermore, investments in emerging market countries are generally subject to additional risks, including trading on smaller markets, having lower volumes of trading, and being subject to lower levels of government regulation and less extensive accounting, financial and other reporting requirements.

Energy Sector Risk—The energy sector is often cyclical and highly dependent on commodities prices. Securities prices for companies in the energy sector may be affected by a variety of factors, including, among others, worldwide energy prices, exploration costs, energy conservation efforts, changes in currency exchange rates, government regulation and market, economic and political risks of the countries where energy companies are located or do business. The Fund may be adversely affected by events or developments negatively impacting the energy sector or issuers within the energy sector.

Equity Securities Risk—The prices of equity securities generally fluctuate in value more than other investments. The prices of equity securities may rise or fall rapidly or unpredictably and reflect changes in the issuing company’s financial condition and changes in the overall market. A decline in the value of equity securities held by the Fund will adversely affect the value of your investment in the Fund. Common stocks generally represent the riskiest investment in a company. The Fund may lose a substantial part, or even all, of its investment in a company’s stock.

Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Foreign Securities and Currency Risk—Foreign securities carry unique or additional risks when compared to U.S. securities, including currency fluctuations, adverse political and economic developments, unreliable or untimely information, less liquidity, limited legal recourse and higher transactional costs.

Geographic Focus Risk—Europe—Because the Fund may focus its investments in Europe, the Fund’s performance may be particularly susceptible to adverse social, political and economic conditions or events within Europe. The European financial markets have recently experienced volatility due to concerns about rising government debt levels of several European countries and increased unemployment levels. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness (which may be located in countries other than those listed in the previous sentence). These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including European Union ("EU") member countries that do not use the euro and non-EU member countries. As a result, the Fund’s performance may be more volatile than the performance of a more geographically diversified fund.

Investment in Investment Companies Risk—Investing in other investment other investment companies, including exchange-traded funds ("ETFs"), closed-end funds and BDCs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying investment companies’ expenses, which will reduce the Fund’s performance, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of substantial premiums above the value of such companies' portfolio securities or net asset values ("NAVs"). In addition, investments by the Fund in another ETF are subject to, among other risks, the risk that the ETF's shares may trade at a discount or premium relative to the NAV of the shares and the listing exchange may halt trading of the ETF's shares.

Issuer-Specific Changes Risk—The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Large-Capitalization Securities Risk—The Fund is subject to the risk that large-capitalization securities may underperform other segments of the equity market or the equity market as a whole. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and may not be able to attain the high growth rate of smaller companies, especially during extended periods of economic expansion.

Market Price Risk—Shares are listed for trading on NYSE Arca, Inc. ("NYSE Arca") and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world because of the interconnected global economies and financial markets.

Mid-Capitalization Securities Risk—The Fund is subject to the risk that mid-capitalization securities may underperform other segments of the equity market or the equity market as a whole. Securities of mid-capitalization companies may be more speculative, volatile and less liquid than securities of large companies. Mid-capitalization companies tend to have inexperienced management as well as limited product and market diversification and financial resources, and may be more vulnerable to adverse developments than large capitalization companies.

Non-Correlation Risk—The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a semi-annual basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other ETFs that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Passive Management Risk—Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund.

Utilities Sector Risk—Stock prices for companies in the utilities sector are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities and rate caps or rate changes. Certain utility companies have experienced full or partial deregulation in recent years. Deregulation may permit certain utility companies to earn more than their traditional regulated rates of return; however, some deregulated companies face greater competition and may be forced to defend their core business and may be less profitable. The Fund may be adversely affected by events or developments negatively impacting the utilities sector or issuers within the utilities sector.
