Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) ^[1] and Rule 19b-4 thereunder,^[2] notice is hereby given that on May 16, 2007, The NASDAQ Stock Market LLC (“Nasdaq”), filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I and II below, which Items have been substantially prepared by Nasdaq. This order provides notice of the proposed rule change and approves the proposal on an accelerated basis.

I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change

Nasdaq proposes to trade, pursuant to unlisted trading privileges (“UTP”), shares (“Shares”) of the PowerShares DB Energy Fund, the PowerShares DB Oil Fund, the PowerShares DB Precious Metals Fund, the PowerShares DB Gold Fund, the PowerShares DB Silver Fund, the PowerShares DB Base Metals Fund, and the PowerShares DB Agriculture Fund (collectively the “Funds”). The text of the proposed rule change is available from Nasdaq's Web site at http://nasdaq.complinet.com, at Nasdaq's principal office, and at the Commission's Public Reference Room.

II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

In its filing with the Commission, Nasdaq included statements concerning the purpose of, and basis for, the proposed rule change and discussed any comments it received on the proposed rule change. The text of these statements may be examined at the places specified in Item III below. Nasdaq has prepared summaries, set forth in Sections A, B, and C below, of the most significant aspects of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

1. Purpose

Nasdaq is proposing to trade the Shares on a UTP basis. The Shares are currently trading on Nasdaq on a three-month pilot basis.^[3] Approval of this filing will allow the Shares to continue to trade after the expiration of the pilot. The Commission previously approved a proposal to list and trade the Shares of the Funds by the American Stock Exchange LLC (the “Amex”).^[4]

The Shares represent beneficial ownership interests in the corresponding Fund's net assets, consisting solely of the common units of beneficial interests of the DB Energy Master Fund, the DB Oil Master Fund, the DB Precious Metals Master Fund, the DB Gold Master Fund, the DB Silver Master Fund, the DB Base Metals Master Fund, and the DB Agriculture Master Fund, respectively (collectively, the “Master Funds”). DB Multi-Sector Commodity Master Trust (the “Master Trust”) is organized as a Delaware statutory trust with each of the Master Funds representing a series of the Master Trust. The Master Funds will hold primarily ^[5] futures contracts ^[6] on the commodities comprising the Deutsche Bank Liquid Commodity Index—Optimum Yield Energy Excess Return^TM, Deutsche Bank Liquid Commodity Index—Optimum Yield Crude Oil Excess Return^TM, Deutsche Bank Liquid Commodity Index—Optimum Yield Precious Metals Excess Return^TM, Deutsche Bank Liquid Commodity Index—Optimum Yield Gold Excess Return^TM, Deutsche Bank Liquid Commodity Index—Optimum Yield Silver Excess Return^TM, Deutsche Bank Liquid Commodity Index Optimum Yield Industrial Metals Excess Return^TM, and Deutsche Bank Liquid Commodity Index—Optimum Yield Agriculture Excess Return^TM (collectively, the “Indexes”), as the case may be. The sponsor of the Indexes is Deutsche Bank AG London (the “Index Sponsor”). Each of the Funds and each of the Master Funds are commodity pools operated by DB Commodity Services LLC (the “Managing Owner”).^[7]

Nasdaq deems the Shares to be equity securities, thus rendering trading in the Shares subject to the Nasdaq's existing rules governing the trading of equity securities, including Rule 4630. The Shares will trade on Nasdaq from 9:30 a.m. until 4:15 p.m. Eastern Time (“ET”), except that shares of the PowerShares DB Base Metals Fund will also trade from 4:15 p.m. until 8 p.m. ET, even if the Indicative Fund Value (“IFV”), as discussed below, is not disseminated from 4:15 p.m. until 8 p.m. ET.^[8] Nasdaq has appropriate rules to facilitate transactions in the Shares during these trading sessions.

Like other exchange-traded fund products, each of the Funds issues and redeems its Shares on a continuous basis at a price equal to the NAV per Share next determined after an order is received in proper form. Also, each of the Funds issues and redeem its Shares only in aggregations of 200,000 shares (“Basket Aggregations”) and only through qualified market participants that have entered into agreements with the Managing Owner (each, an “Authorized Participant”). Additional information about the creation and redemption process is included in the Amex Order. In summary, to create Shares, an Authorized Participant must properly place a creation order and ( printed page 32381) deliver the specified “cash deposit amount” ^[9] and applicable transaction fee to The Bank of New York (the “Fund Administrator”). The Fund Administrator will issue to the Authorized Participant the appropriate number of Basket Aggregations. To redeem Shares, an Authorized Participant must properly place a redemption order and deliver Shares that in the aggregate constitute one or more Basket Aggregations, plus any applicable transaction fee. The Fund Administrator will deliver the appropriate “cash redemption amount” ^[10] for each Basket Aggregation that an Authorized Participant redeems.

On each business day, the Administrator makes available immediately prior to the opening of trading on Amex, through the facilities of the Consolidated Tape Association (“CTA”), the Basket Amount for the creation of a Basket. According to the Amex Order, Amex disseminates every 15 seconds throughout the trading day, via the facilities of the CTA, an amount representing on a per-Share basis, the current values of the Basket Amounts for each of the Funds.

After 4 p.m. ET each business day, the Administrator determines the NAV for each of the Funds, utilizing the current settlement value of the particular commodity futures contracts. The calculation methodology for the NAV is described in more detail in the Amex Order. After 4 p.m. ET each business day, the Administrator, Amex, and the Managing Owner disseminate the NAVs for the Shares and the Basket Amounts (for orders placed during the day). The Basket Amounts and the NAVs are communicated by the Administrator to all Authorized Participants via facsimile or e-mail, and the NAV is available on the Funds' Web site at http://www.dbfunds.db.com .^[11]

Quotations for and last-sale information regarding the Shares are disseminated through the Consolidated Tape System (“CTS”). The Index Sponsor publishes the value of each of the Indexes at least once every 15 seconds throughout each trading day on the CTA, Bloomberg, Reuters, and on the Fund's Web site at http://www.dbfunds.db.com. The closing Index levels similarly are provided by the Index Sponsor. In addition, any adjustments or changes to the Indexes are provided by the Index Sponsor and Amex on their respective Web sites.

The Web site for the Funds at http://www.powershares.com , which is publicly accessible at no charge, contains the following information: (a) The current NAV per Share daily and the prior business day's NAV and the reported closing price; (b) the mid-point of the bid-ask price in relation to the NAV as of the time the NAV is calculated (the “Bid-Ask Price”);^[12] (c) the calculation of the premium or discount of such price against such NAV; (d) data in chart form displaying the frequency distribution of discounts and premiums of the Bid-Ask Price against the NAV, within appropriate ranges for each of the four previous calendar quarters; (e) the prospectus; and (f) other applicable quantitative information.

As described above, the respective NAVs for the Funds are calculated and disseminated daily to all market participants at the same time. According to the Amex Order, Amex also intends to disseminate for each of the Funds on a daily basis by means of CTA/CTS High Speed Lines information with respect to the corresponding IFV (as discussed below), recent NAV, and shares outstanding. Amex will also make available on its Web site daily trading volume of the Shares of each of the Funds, closing prices of such Shares, and the corresponding NAV. The closing price and settlement prices of the futures contracts comprising the Indexes and held by the corresponding Master Funds are also readily available from the relevant futures exchanges, automated quotation systems, published or other public sources, or on-line information services such as Bloomberg or Reuters.

Amex has represented that it will disseminate through the facilities of the CTA an updated IFV for each of the Funds. The respective IFVs will be disseminated on a per-Share basis at least every 15 seconds from 9:30 a.m. to 4:15 p.m. ET, according to the Amex Order. The IFVs will be calculated based on the cash required for creations and redemptions for the respective Funds adjusted to reflect the price changes of the corresponding Index commodities through investments held by the Master Funds, i.e., futures contracts. The IFVs will not reflect price changes to the price of an underlying commodity between the close of trading of the futures contract at the relevant futures exchange and 4:15 p.m. ET. While the Shares will trade on Nasdaq from 9:30 a.m. to 4:15 p.m. ET (and until 8 p.m. ET in the case of the shares of the PowerShares DB Base Metals Fund), regular trading hours for each of the Index commodities on the various futures exchanges vary widely, as set forth in detail in the Amex Order. Therefore, the value of a Share may be influenced by non-concurrent trading hours between the Nasdaq and the various futures exchanges on which the futures contracts based on the Index commodities are traded.

Nasdaq will halt trading in the Shares under the conditions specified in Nasdaq Rules 4120 and 4121. The conditions for a halt include a regulatory halt by the listing market. UTP trading in the Shares will also be governed by provisions of Nasdaq Rule 4120 relating to temporary interruptions in the calculation or wide dissemination of the IFV or the value of the Index. Additionally, Nasdaq may cease trading the Shares if other unusual conditions or circumstances exist which, in the opinion of Nasdaq, make further dealings on Nasdaq detrimental to the maintenance of a fair and orderly market. Nasdaq will also follow any procedures with respect to trading halts as set forth in Nasdaq Rule 4120(c). Finally, Nasdaq will stop trading the Shares if the listing market delists them.

Nasdaq believes that its surveillance procedures are adequate to address any concerns about the trading of the Shares on Nasdaq. Trading of the Shares through Nasdaq facilities is currently subject to NASD's surveillance procedures for equity securities in general and ETFs in particular.^[13] Nasdaq is able to obtain information regarding trading in the Shares and the underlying futures contracts through its members in connection with the proprietary or customer trades that such members effect on any relevant market. In addition, Nasdaq may obtain trading information via the Intermarket Surveillance Group (“ISG”) from other exchanges who are members or affiliates of the ISG, including the CBOT and the NYBOT, and Nasdaq has Information Sharing Agreements in place with ICE, NYMEX, and LME. Nasdaq has issued an Information Circular to inform its members of the special characteristics and risks associated with trading the Shares.

2. Statutory Basis

Nasdaq believes that the proposal is consistent with Section 6(b) of the Act ^[14] in general and Section 6(b)(5) of the Act ^[15] in particular, in that in that it is designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, remove impediments to a free and open market and a national market system, and, in general, to protect investors and the public interest. In addition, Nasdaq believes that the proposal is consistent with Rule 12f-5 under the Act ^[16] because it deems the Shares to be an equity securities, thus rendering trading in the Shares subject to Nasdaq's existing rules governing the trading of equity securities.

B. Self-Regulatory Organization's Statement on Burden on Competition

Nasdaq does not believe that the proposed rule change will impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act.

C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants or Others

Written comments on the proposed rule change were neither solicited nor received.

III. Solicitation of Comments

Interested persons are invited to submit written data, views, and arguments concerning the foregoing, including whether the proposed rule change is consistent with the Act. Comments may be submitted by any of the following methods:

• Send paper comments in triplicate to Nancy M. Morris, Secretary, Securities and Exchange Commission, 100 F Street, NE., Washington, DC 20549-1090.

IV. Commission's Findings and Order Granting Accelerated Approval of the Proposed Rule Change

After careful review, the Commission finds that the proposed rule change is consistent with the requirements of the Act and the rules and regulations thereunder applicable to a national securities exchange.^[17] In particular, the Commission finds that the proposed rule change is consistent with Section 6(b)(5) of the Act,^[18] which requires that an exchange have rules designed, among other things, to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and in general to protect investors and the public interest. The Commission believes that this proposal should benefit investors by increasing competition among markets that trade the Shares.

In addition, the Commission finds that the proposal is consistent with Section 12(f) of the Act,^[19] which permits an exchange to trade, pursuant to UTP, a security that is listed and registered on another exchange.^[20] The Commission notes that it previously approved the listing and trading of the Shares on Amex.^[21] The Commission also finds that the proposal is consistent with Rule 12f-5 under the Act,^[22] which provides that an exchange shall not extend UTP to a security unless the exchange has in effect a rule or rules providing for transactions in the class or type of security to which the exchange extends UTP. The Exchange has represented that it meets this requirement because it deems the Shares to be equity securities, thus rendering trading in the Shares subject to the Exchange's existing rules governing the trading of equity securities.

The Commission further believes that the proposal is consistent with Section 11A(a)(1)(C)(iii) of the Act,^[23] which sets forth Congress' finding that it is in the public interest and appropriate for the protection of investors and the maintenance of fair and orderly markets to assure the availability to brokers, dealers, and investors of information with respect to quotations for and transactions in securities. Quotations for and last-sale information regarding the Shares are disseminated through the facilities of the CTA and the Consolidated Quotation System. Furthermore, the IFV of each Fund is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund is listed or by other information providers or market data vendors.

The Commission also believes that the Exchange's trading halt rules are reasonably designed to prevent trading in an ETF when transparency is impaired. Nasdaq will halt trading in the Shares under the conditions specified in Nasdaq Rules 4120 and 4121. The conditions for a halt include a regulatory halt by the listing market. UTP trading in the Shares will also be governed by provisions of Nasdaq Rule 4120 relating to temporary interruptions in the calculation or wide dissemination of the IFV or the value of the Index. Additionally, Nasdaq may cease trading the Shares if other unusual conditions ( printed page 32383) or circumstances exist which, in the opinion of Nasdaq, make further dealings on Nasdaq detrimental to the maintenance of a fair and orderly market. Nasdaq will also follow any procedures with respect to trading halts as set forth in Nasdaq Rule 4120(c).

The Commission notes that, if the Shares should be delisted by the listing exchange, the Exchange would no longer have authority to trade the Shares pursuant to this order.

In support of this proposal, the Exchange has represented that its surveillance procedures are adequate to properly monitor Exchange trading of the Shares in all trading sessions and to deter and detect violations of Exchange rules. This approval order is conditioned on the Exchange's adherence to this representation.

In addition, the Commission recently approved the trading of the Shares on the Exchange pursuant to UTP for a pilot period of three months.^[24] In the Pilot Order, the Commission noted that exchanges that trade commodity-related securities generally have in place surveillance arrangements with markets that trade the underlying securities. In its proposal to trade the Shares for a pilot period, the Exchange represented that it was in the process of completing these surveillance arrangements and expected to do so “in the near future.” The Exchange recently provided the Commission with evidence that it has completed these surveillance arrangements.

The Commission finds good cause for approving this proposal before the thirtieth day after the publication of notice thereof in the Federal Register . As noted previously, the Commission previously found that the listing and trading of the Shares on Amex is consistent with the Act. The Commission presently is not aware of any regulatory issue that should cause it to revisit that finding or would preclude the trading of the Shares on the Exchange pursuant to UTP. Therefore, accelerating approval of this proposal should benefit investors by creating, without undue delay, additional competition in the market for the Shares.

V. Conclusion

It is therefore ordered , pursuant to Section 19(b)(2) of the Act,^[25] that the proposed rule change (SR-NASDAQ-2007-053) thereto, be and it hereby is, approved on an accelerated basis.
