Documents

1. Special Risks Small-sized company stock is typically more volatile than that of larger company stock. It may take a substantial period of time to realize a gain on an investment in a small-sized company, if any gain is realized at all. Diversification does not guarantee profit or protect against loss.
2. Class I shares are only offered to eligible institutional investors that make a minimum initial investment of $1 million or more and to retirement plan service provider platforms. The minimum account balance for class I shares is $2.5 million. Class I shares are sold at net asset value without a sales charge. Please see Fund prospectuses for additional information.
3. The net expense ratio (where applicable) also takes into account contractual fee waivers and/or expense reimbursements without which performance would have been less. These undertakings may not be amended or withdrawn for one year from the date of the current prospectus, unless approved by the Board.
4. Access index definitions.
5. Holdings are subject to change, and are dollar weighted based on total net assets. Negative weightings may result from the use of leverage. Leverage involves the use of various financial instruments or borrowed capital in an attempt to increase investment return. Leverage risks include potential for higher volatility, greater decline of the fund's net asset value and fluctuations of dividends and distributions paid by the fund.
6. Holdings are subject to change, are dollar-weighted based on assets, and may not reflect the use of leverage in the Fund. Market Cap breakdown is calculated using Morningstar's methodology and those capitalization standards may not align with those in the Fund’s prospectus.
A. Daily net asset value and dollar change of the fund is as of the previous business day's closing. Fund net asset values are updated at approximately 7:00pm ET daily. ↩
B. The performance data quoted represents past performance, which does not guarantee future results. The investments return and principal value of an investment in the Fund will fluctuate so that an investor's shares, when redeemed, may be worth more or less than the original cost. Current performance and expense ratios may be lower or higher than the data quoted. Fund returns include changes in share price and reinvested distributions. Class I shares are not subject to a sales charge. Returns do not consider capital gains or income taxes on an individual's investment. ↩
C. "Year to Date" returns are cumulative, not annualized, and do not reflect sales charges (if sales charges are applicable to the Fund). These returns would be lower if sales charges were taken into consideration. Short-term returns may not be indicative of longer-term performance, which should also be considered when making investment decisions. ↩
D. There is no guarantee of the payment of any dividend or other distributions at any level. ↩

The funds invest in below-investment-grade debt securities, which may entail greater credit risks, as described in each fund’s prospectus. These securities (sometimes called “junk bonds”) may be subject to greater price fluctuations and risks of loss of income and principal than investment-grade municipal securities. The funds may invest substantially in municipal securities within a single state or related to similar type projects, which can increase volatility and exposure to regional issues. The funds may also invest substantially in Puerto Rico and other U.S. territories, commonwealths and possessions, and could be exposed to their local political and economic conditions. Deterioration of the Puerto Rican economy could have an adverse impact on Puerto Rican bonds and the performance of the Rochester municipal funds that hold them.The views represented herein are the opinions of the Portfolio Managers at Macquarie Capital Investment Management LLC and are not intended as investment advice or to predict or depict the performance of any investment. These views are as of the date indicated, and are subject to change based on subsequent developments.Funds returns may not match the return of its respective index, known as non-correlation risk, due to operating expenses incurred by the Funds. The alternate weighting approach employed by the Funds (i.e., using revenues as a weighting measure), while designed to enhance potential returns, may not produce the desired results. Because the Funds are rebalanced quarterly, portfolio turnover may exceed 100%. The greater the portfolio turnover, the greater the transaction costs, which could have an adverse effect on Fund performanceOn April 28, 2017, OFI Global Institutional, Inc., a registered investment adviser subsidiary within OFI Global Asset Management (“OFI Global”) acquired SNW Asset Management, LLC (“SNW”).
