NOTES TO SCHEDULE OF INVESTMENTS (Unaudited)                                                        

For information on the Claymore Exchange–Traded Fund Trust’s (the “Trust”) policy regarding valuation of investments and other significant accounting policies, please refer to the Trust’s most recent semiannual or annual shareholder report.

1.  Significant Accounting Policies

The following significant accounting policies are in conformity with U.S. generally accepted accounting principles ("GAAP") and are consistently followed by the Trust. This requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

The Board of Trustees of the Funds (the “Board”) has adopted policies and procedures for the valuation of the Funds’ investments (the “Valuation Procedures”). Pursuant to the Valuation Procedures, the Board has delegated to a valuation committee, consisting of representatives from Guggenheim’s investment management, fund administration, legal and compliance departments (the “Valuation Committee”), the day-to-day responsibility for implementing the Valuation Procedures, including, under most circumstances, the responsibility for determining the fair value of the Funds’ securities or other assets.

Valuations of the Funds’ securities are supplied primarily by pricing services appointed pursuant to the processes set forth in the Valuation Procedures. The Valuation Committee convenes monthly, or more frequently as needed and will review the valuation of all assets which have been fair valued for reasonableness. The Funds’ officers, through the Valuation Committee and consistent with the monitoring and review responsibilities set forth in the Valuation Procedures, regularly review procedures used by, and valuations provided by, the pricing services.

If the pricing service cannot or does not provide a valuation for a particular security or such valuation is deemed unreliable, such security is fair valued by the Valuation Committee.

Equity securities listed on an exchange (New York Stock Exchange (“NYSE”) or American Stock Exchange) are valued at the last quoted sales price as of the close of U.S. business on the NYSE, usually 4:00 p.m. Eastern time on the valuation date. Equity securities listed on the NASDAQ market system are valued at the NASDAQ Official Closing Price on the valuation date, which may not necessarily represent the last sale price. If there has been no sale on such exchange or NASDAQ on such day, the security is valued at the mean of the most recent bid and ask prices on such day.

Open-end investment companies (“Mutual Funds”) are valued at their NAV as of the close of business on the valuation date. Exchange Traded Funds (“ETFs”) and closed-end investment companies are valued at the last quoted sales price.

U.S. government securities are valued by either independent pricing services, the last traded fill price, or at the reported bid price at the close of business. Debt securities with a maturity of greater than 60 days at acquisition are valued at prices that reflect broker/dealer supplied valuations or are obtained from independent pricing services, which may consider the trade activity, treasury spreads, yields or price of bonds of comparable quality, coupon, maturity, and type, as well as prices quoted by dealers who make markets in such securities. Short-term securities with remaining maturities of 60 days or less are valued at market price, or if a market price is not available, at amortized cost, provided such amount approximates market value. Money market funds are valued at net asset value.

Typically loans are valued using information provided by an independent third party pricing service which uses broker quotes. If the pricing service cannot or does not provide a valuation for a particular loan or such valuation is deemed unreliable, such loan is fair valued by the Valuation Committee.

Generally, trading in foreign securities markets is substantially completed each day at various times prior to the close of the NYSE. The values of foreign securities are determined as of the close of such foreign markets or the close of the NYSE, if earlier. All investments quoted in foreign currency are valued in U.S. dollars on the basis of the foreign currency exchange rates prevailing at the close of U.S. business at 4:00 p.m. Eastern time.  Investments in foreign securities may involve risks not present in domestic investments. The Valuation Committee will determine the current value of such foreign securities by taking into consideration certain factors which may include those discussed above, as well as the following factors, among others: the value of the securities traded on other foreign markets, ADR trading, closed-end fund trading, foreign currency exchange activity, and the trading prices of financial products that are tied to foreign securities such as World Equity Benchmark Securities. In addition, under the Valuation Procedures, the Valuation Committee and Guggenheim Funds Investment Advisors, LLC (“GFIA” or

the “Investment Adviser”) are authorized to use prices and other information supplied by a third party pricing vendor in valuing foreign securities.

Investments for which market quotations are not readily available are fair valued as determined in good faith by the Investment Adviser, subject to review by the Valuation Committee, pursuant to methods established or ratified by the Board. Valuations in accordance with these methods are intended to reflect each security’s (or asset’s) “fair value.” Each such determination is based on a consideration of all relevant factors, which are likely to vary from one pricing context to another. Examples of such factors may include, but are not limited to: (i) the type of security, (ii) the initial cost of the security, (iii) the existence of any contractual restrictions on the security’s disposition, (iv) the price and extent of public trading in similar securities of the issuer or of comparable companies, (v) quotations or evaluated prices from broker/dealers and/or pricing services, (vi) information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange traded securities), (vii) an analysis of the company’s financial statements, and (viii) an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold (e.g. the existence of pending merger activity, public offerings or tender offers that might affect the value of the security).

2.  Fair Value Measurement

In accordance with GAAP, fair value is defined as the price that the Funds would receive to sell an investment or pay to transfer a liability in an orderly transaction with an independent buyer in the principal market, or in the absence of a principal market, the most advantageous market for the investment or liability. GAAP establishes a three-tier fair value hierarchy based on the types of inputs used to value assets and liabilities and requires corresponding disclosure. The hierarchy and the corresponding inputs are summarized below:

Level 1 — quoted prices in active markets for identical assets or liabilities.

Level 2 — significant other observable inputs (for example quoted prices for securities that are similar based on characteristics such as interest rates, prepayment speeds, credit risk, etc.).

Level 3— significant unobservable inputs based on the best information available under the circumstances, to the extent observable inputs are not available, which may include assumptions.

The types of inputs available depend on a variety of factors, such as the type of security and the characteristics of the markets in which it trades, if any. Fair valuation determinations that rely on fewer or no observable inputs require greater judgment. Accordingly, fair value determinations for Level 3 securities require the greatest amount of judgment.

The following tables summarize the inputs used to value the Funds’ investments at August 31, 2015:

Independent pricing services are used to value a majority of the Funds’ investments. When values are not available from a pricing service, they will be determined under the valuation policies that have been reviewed and approved by the Board of Trustees. In any event, values are determined using a variety of sources and techniques, including: market prices; broker quotes; and models which derive prices based on inputs such as prices of securities with comparable maturities and characteristics or based on inputs such as anticipated cash flows or collateral, spread over Treasuries, and other information and analysis. A significant portion of the Funds’ assets and liabilities are categorized as Level 2.

Indicative quotes from broker-dealers, adjusted for fluctuations in criteria such as credit spreads and interest rates, may be also used to value the Funds’ assets and liabilities, i.e. prices provided by a broker-dealer or other market participant what has not committed to trade at that price. Although indicative quotes are typically received from established market participants, the Funds may not have the transparency to view the underlying inputs which support the market quotations. Significant changes in an indicative quote would generally result in significant changes in the fair value of the security.

Certain fixed income securities are valued by obtaining a monthly indicative quote from a broker-dealer, adjusted for fluctuations in criteria such as credit spreads and interest rates. The Funds’ fair valuation guidelines were recently revised to transition such monthly indicative quoted securities from Level 2 to Level 3.

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The suitability of the techniques and sources employed to determine fair valuation are regularly monitored and subject to change.

Transfers between investment levels may occur as the markets fluctuate and/or the availability of data used in an investment’s valuation changes. Transfers between valuation levels, if any, are in comparison to the valuation levels at the end of the previous fiscal year, and are effective using the fair value as of the end of the current period.

The transfers in and out of the valuation levels as of August 31, 2015 compared to the valuation levels at the end of the previous fiscal year are detailed below:

Guggenheim Enhanced Short Duration ETF
Transfer from Level 3 to Level 2	$473,522

The transfer from Level 3 to Level 2 was due to the availability of market price information for the respective security at August 31, 2015.

Except for Guggenheim Enhanced Short Duration ETF, there were no transfers between levels for the Funds for the period ended August 31, 2015.

Summary of Fair Value Level 3 Activity

Following is a reconciliation of Level 3 assets for which significant unobservable inputs were used to determine fair value for the period ended August 31, 2015:

4.  Portfolio Securities Loaned

Each Fund may lend portfolio securities to certain creditworthy borrowers, including the Funds’ securities lending agent. The loans are collateralized at all times by cash and/or high grade debt obligations in an amount at least equal to 102% of the market value of domestic securities loaned and 105% of foreign securities loaned as determined at the close of business on the preceding business day. The cash collateral received is held in a separately managed account established for each respective Fund and maintained by the lending agent exclusively for the investment of securities lending cash collateral on behalf of each Fund. The separately managed accounts invest in short-term investments valued at amortized cost, which approximates market value. Each Fund receives compensation for lending securities from interest or dividends earned on the cash, cash equivalents or U.S. government securities held

as collateral, net of fee rebates paid to the borrower plus reasonable administrative and custody fees paid to the lending agent. Such compensation is accrued daily and payable to the Fund monthly. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. The borrower pays to the Funds an amount equal to any dividends or interest received on loaned securities. These payments from the borrower are not eligible for reduced tax rates as “qualified dividend income” under the Jobs and Growth Tax Reconciliation Act of 2003. The Funds retain all or a portion of the interest received on investment of cash collateral or receive a fee from the borrower. Lending portfolio securities could result in a loss or delay in recovering each Fund’s securities if the borrower defaults.

As of August 31, 2015, the Funds participated in securities lending as follows:

5.  Repurchase Agreements

Each of the Funds may engage in repurchase agreements. Repurchase agreements are fixed income securities in the form of agreements backed by collateral. These agreements typically involve the acquisition by the Fund of

securities from the selling institution 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. The Fund may accept a wide variety of

underlying securities as collateral for the repurchase agreements entered into by the Fund. Any such securities serving as collateral are marked-to-market daily in order to maintain full collateralization.

The use of repurchase agreements involves certain risks. For example, if the selling institution defaults on its obligation to repurchase the underlying securities at a time when the value of securities has declined, the Fund may incur a loss upon disposition of them. In the event of an insolvency or bankruptcy by the selling institution, the Funds right to control the collateral could be affected and result in certain costs and delays. In addition, the Fund could incur a loss if the value of the underlying collateral falls below the agreed upon repurchase price.

As of August 31, 2015, the repurchase agreements held in Guggenheim Enhanced Short Duration ETF in the joint account were as follows:
