NOTES TO SCHEDULES OF INVESTMENTS (Unaudited)

ORGANIZATION

The Oppenheimer Revenue Weighted ETF Trust (the “Trust”) was organized as a Delaware statutory trust on December 15, 2006 and has authorized capital of unlimited shares. The Trust is an open-end management investment company, registered under the Investment Company Act of 1940, as amended (the “Act”), which, as of the date of this report, is comprised of ten active funds (collectively, the “Funds” and each individually a “Fund”). The Funds are investment companies and accordingly follow the Investment Company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946 Financial Services Investment Companies. The Oppenheimer Large Cap Revenue ETF, the Oppenheimer Mid Cap Revenue ETF, the Oppenheimer Small Cap Revenue ETF, the Oppenheimer Global ESG Revenue ETF, the Oppenheimer ESG Revenue ETF, the Oppenheimer Global Revenue ETF, the Oppenheimer International Revenue ETF, and the Oppenheimer Emerging Markets Revenue ETF are diversified funds under the Act. The Oppenheimer Financials Sector Revenue ETF and the Oppenheimer Ultra Dividend Revenue ETF are not diversified. Each Fund’s investment objective is to outperform the total return performance of the Fund’s corresponding benchmark index (each a “Benchmark Index” and, collectively, the “Benchmark Indexes”). The Trust’s investment adviser is VTL Associates, LLC (“VTL” or the “Adviser”).

The following is a summary of significant accounting policies followed in the Funds’ preparation of financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”).

Securities Valuation

The Net Asset Value (“NAV”) per share of each Fund is computed by dividing the value of the net assets of each Fund by the total number of outstanding shares of that Fund, rounded to the nearest cent. The Bank of New York Mellon calculates each Fund’s NAV as of 4:00 p.m., Eastern Time on each day that the NYSE is open, except in the case of a scheduled early closing of the NYSE, in which case the Fund will calculate the NAV of the shares as of the scheduled early closing time of the NYSE.

Valuation Methods and Inputs. Securities traded on a national securities exchange are valued based on the official closing price. Price information on listed securities is taken from the exchange where the security is primarily traded. Securities regularly traded in an over the counter market are valued at the official closing price. Other portfolio securities and assets for which market quotations are not readily available are valued based on fair value as determined in good faith and in accordance with procedures adopted by the Trust’s Board.

Short-term money market type debt securities are valued at the mean between the “bid” and “asked” prices utilizing evaluated prices obtained from third party pricing services or broker-dealers.

The authoritative guidance for fair value measurements and disclosures, Accounting Standards Codification™ Topic 820 (“Topic 820”), establishes an authoritative framework for the measurement of fair value, and enhances disclosures about fair value measurements. Furthermore, Topic 820 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring the most observable inputs be used when available. The Funds utilized various inputs in determining the value of each Fund’s investments. These inputs are summarized in the three broad levels as follows:

Level 1 — quoted prices in active markets for identical securities

Level 2 — other significant observable inputs (including quoted prices in an active market for similar securities, the intrinsic value of securities such as rights, warrants or options, etc.)

Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The following summarizes inputs used as of September 30, 2017 in valuing the Funds’ assets carried at fair value:

	(Level 1)						(Level 2)						(Level 3)

At September 30, 2017, the Funds did not hold any Level 3 securities. Please refer to each Fund’s Schedule of Investments to view equity securities segregated by industry type.

The Funds’ policy is to disclose transfers between Levels based on valuations at the beginning of the reporting period.

For the period ended September 30, 2017, there were no transfers between levels.
