A disparate global economic landscape has formed, with the U.S. facing prospects for continued growth, while questions abound regarding the outlook for other regions. Employment, household income, and corporate profits have been rising in the U.S. and inflation pressures remain low. However, many countries across Europe as well as Japan face muted growth. In addition, a variety of factors have clouded the outlook for countries such as Russia and Brazil and China's investment-driven economy continues to slow. Monetary policies of major central banks are diverging, reflecting different economic conditions. With the U.S. economy no longer in need of extraordinary stimulus, the Federal Reserve Board may be closer to raising short-term interest rates. Conversely, the European Central Bank and the Bank of Japan are likely to be adding, not removing, stimulus. While we anticipate continued growth for the U.S., the outlook is far from certain, nor is the outlook for other regions necessarily dire. It remains to be seen how weakness outside the U.S. will affect global growth and whether easing monetary policies in other regions will spur an economic recovery. While these economic conditions may lead to increasing volatility in 2015, we believe the opportunity for investors to earn attractive returns will persist. However, in an environment where interest rates remain low and equity valuations have been buoyed by an extended bull market, we believe it is imperative investors adhere to a disciplined investment approach that is consistent with one's goals and objectives, being mindful of the tradeoff between risk and return. Since 1928 Pioneer's investment professionals have been focused on identifying and capitalizing on investment opportunities that present themselves in a variety of ever changing market conditions, including those we face today. We seek returns consistent with our strategies' stated style and 2 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 objectives and consistent with our shareholders' expectations, regardless of market conditions. We believe our shareowners benefit from the experience and tenure of our investment teams, the insights generated from extensive research resources and a commitment to prudent risk management designed to mitigate downside and preserve returns over time. We encourage you to work with your financial advisor to develop an overall investment plan that addresses both your short- and long-term goals, and to implement such a plan in a disciplined manner, as we do when deploying strategies on behalf of our shareowners. We greatly appreciate your trust in us in the past and look forward to continuing to serve you in the future. Sincerely, /s/ Lisa M. Jones Lisa M.

Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 3 Portfolio Management Discussion | 11/30/14 For the 12-month period ended November 30, 2014, returns for Pioneer Select Mid Cap Growth Fund underperformed the return of the Fund's benchmark, the Russell Midcap Growth Index, but exceeded the average returns of the Mid Cap Growth funds tracked by both Lipper and Morningstar. In the following interview, Ken Winston reviews the investment background and details some of the factors and decisions that drove the Fund's performance during the 12-month period. Mr. Winston, a vice president and a portfolio manager at Pioneer, is responsible for the day-to-day management of the Fund, along with Shaji John, a vice president and a portfolio manager at Pioneer, and Jon Stephenson, a vice president and a portfolio manager at Pioneer. Q How would you describe the investment environment for mid-cap equities during the 12-month period ended November 30, 2014? A Mid-cap stocks traced a very jagged path upward over the full 12-month period. Along the way, share prices of equities suffered four steep downturns that were triggered by such factors as disruptive winter weather in 2013-2014, weakening global economic growth, the Ebola virus outbreak and expectations of interest-rate hikes in 2015. In the long run, however, investors chose to focus on the strengthening U.S. economy as their best source of opportunity. Falling commodity prices and the near-absence of inflation were additional factors favoring the performance of equities. Towards the end of the period, lower energy prices acted as a de facto stimulus for the domestic economy, putting more money in the pockets of consumers and reducing operating expenses for businesses. At the same time, low levels of inflation gave the U.S. Federal Reserve System (the Fed) the leeway to delay any potential rate increases. Oil and gas prices, already slumping, dropped even further when the OPEC cartel (Organization of Petroleum Exporting Countries) opted to maintain current production levels. During the period, market participants favored owning stocks of larger rather than smaller companies. Thus, mid-cap portfolio managers and shareholders were rewarded if their investment choices tilted toward larger issues within the mid-cap style range. Q How did the Fund perform in that environment during the 12-month period ended November 30, 2014? A Pioneer Select Mid Cap Growth Fund's Class A shares returned 13.30% at net asset value during the 12-month period ended November 30, 2014, while the Fund's benchmark, the Russell Midcap Growth Index (the Russell Index), returned 15.80%. During the same period, the average return of the 4 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 419 mutual funds in Lipper's Mid Cap Growth Funds category was 10.40%, and the average return of the 747 mutual funds in Morningstar's Mid Cap Growth Funds category was 10.29%. Q Which of your investment strategies either contributed to or detracted from the Fund's performance during the 12-month period ended November 30, 2014? A The Fund underperformed the Russell Index during the 12-month period primarily because of unfavorable stock selection results. From an asset allocation perspective within the various market sectors, the Fund's positioning versus the benchmark was essentially neutral to relative performance. Health care, telecom services, utilities and consumer staples were the top-performing sectors in the Russell Index during the period. Meanwhile, energy, the worst-performing sector, finished in negative territory and consumer discretionary, while positive for the period, was the second-worst performer. Accordingly, the Fund's overweight in health care and an underweight in consumer discretionary benefited benchmark-relative performance. A greater-than-benchmark portfolio weighting in the slumping energy sector, plus underexposure to the strong telecom services and consumer staples sectors, essentially offset those positives. The Fund's sector weightings are not determined in advance, but are the result of our stock selection process. Health care delivered the best returns for the Fund relative to the benchmark when both stock selection and the effects of sector weightings are taken into consideration. Stock selection was also strong in the consumer staples sector, although that benefit was diluted somewhat by the portfolio's aforementioned underweight position. Stock selection in information technology also contributed to the Fund's benchmark-relative performance, while selection in six sectors - industrials, consumer discretionary, materials, energy, financials and utilities, in that order - held back the Fund's relative returns. Q Which individual holdings had the greatest positive effect on the Fund's performance during the 12-month period ended November 30, 2014? A The Fund's two best-performing stock positions during the period were American Airlines Group and Keurig Green Mountain. American's shares made the strongest contribution to the Fund's results over the period, encompassing the first four quarters after the merger between AMR Corp. (American's former parent) and U.S. Airways. The share price rose as investors began to appreciate the significantly enhanced earnings potential of the combined company. Keurig Green Mountain, a consumer staples firm that makes and distributes the popular Keurig one-cup coffee brewing Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 5 system, is the industry leader in that area. Early in 2014, Keurig Green Mountain's shares advanced sharply on news of a partnership with Coca-Cola (not in the portfolio). The two companies are developing a new single-serve counter-top system for cold beverages. Coca-Cola has also made a direct investment of up to 20% in Keurig Green Mountain. Other top performers for the Fund in consumer staples during the period were Monster Beverage and Constellation Brands, which aided relative results. In addition, our avoidance of Avon Products and Whole Foods Markets, both of which materially underperformed, helped the Fund's benchmark-relative returns in the consumer staples sector. In information technology, a position in Skyworks Solutions, which makes complete semiconductor solutions for mobile communications, was a standout performer for the Fund over the period. The shares appreciated greatly after the company reported strong results in consecutive quarters. Skyworks is also increasing its share of semiconductor content for mobile phones, including Apple's (not in the portfolio) newest iPhones, which have complex, specialized requirements. In health care, the Fund realized strong contributions from several portfolio holdings in the sector. Shares of Neurocrine Biosciences, a biopharmaceutical company, rose after the company reported positive Phase II results for a drug that targets movement disorders. In addition, Elagolix, Neurocrine's leading new product candidate, has shown positive Phase II trial data for the treatment of endometriosis and uterine fibroids. A position in Akorn Pharmaceuticals, which makes a wide range of ophthalmic and injectable therapies, was another strong performer during the 12-month period, while the Fund's shares of Shire rose based on strong results and its agreement to merge with AbbVie. The proposed merger eventually fell apart, but only after we had decided to take profits and sell the Fund's position in Shire. Q Which individual holdings detracted the most from the Fund's returns during the 12-month period ended November 30, 2014? A In energy, a position in Goodrich Petroleum, a Houston-based exploration and production company with assets in the Tuscaloosa Marine Shale and elsewhere, hurt the Fund's benchmark-relative performance the most during the 12-month period. Goodrich's shares declined in price when it became clear that the company's drilling and completion activities could not live up to Wall Street's expectations, given the collapse of oil prices as the period progressed. In industrials, a portfolio position in Chart Industries, which manufactures highly engineered cryogenic equipment for the natural gas industry, hurt benchmark-relative performance as the 6 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 company's share price fell after it disclosed that the timing of certain orders and shipments to China would fail to meet previous expectations. In consumer discretionary, the Fund's position in LKQ, a leading provider of refurbished parts for cars and trucks, also detracted from benchmark-relative performance. During the period, an independent short-seller newsletter accused LKQ of using overly aggressive accounting methods with respect to the company's acquisitions, which hurt the stock price. In our opinion, the claims are exaggerated, and we maintain our positive outlook for LKQ, based on its compelling growth potential and well- informed acquisition strategy. Q Did you use derivative investments in managing the Fund during the 12-month period ended November 30, 2014, and did the derivatives have an effect on performance? A Yes, we did use derivatives during the period. Specifically, we sold call options against the shares of some companies we held in the portfolio. We did this in order to generate short-term income while still being able to retain those stocks in the portfolio. The selling of the call options made a minor, yet positive contribution to the Fund's performance during the period. Q What is your investment outlook? A The Fed has signaled its intention to raise short-term interest rates sometime in 2015. Ideally, such changes would be gradual and carefully timed so as not to disrupt the economic comfort zone in which corporations have been functioning so smoothly. We believe equity prices should be able to weather such a measured approach. For that matter, we believe rate hikes appear far from certain to occur, as falling commodity prices are constraining domestic inflation, while slackening global economic growth also argues against near-term rate increases. Although the U.S. economic expansion appears poised to continue, shortfalls in global growth or a miscalculation by the Fed could derail the long-running bull market. Also, the sharp drop in oil and gas prices implies a reduction of capital spending, much of which is normally seen in the energy sector. For next year, we see potential for respectable corporate earnings expansion in an environment of modest overall domestic economic growth. Equity returns have been understandably less robust than in earlier stages of the economic recovery as world economies have faced their own challenges, and continued weakness overseas could hold back economic growth at home. Also, the twin specters of continued geopolitical turmoil and the possibility of a resurgent, more aggressive spread of Ebola remain serious risks to U.S. investor confidence. Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 7 Overall, however, we feel the most likely scenario features sustainable, but moderate economic growth against a background of manageable inflation. That scenario will mostly favor companies such as those we strive to hold in the Fund's portfolio; corporations that we feel have the potential to grow over the long run, despite periodic economic setbacks. Searching for companies with sustainable growth prospects that are available at reasonable valuations in a diversified* portfolio will continue to define our investment strategy. * Diversification does not assure a profit nor protect against loss in a declining market.

Investments in mid-sized companies may offer the potential for higher returns, but are also subject to greater short-term price fluctuations than larger, more established companies. When interest rates rise, the prices of fixed income securities in the fund will generally fall. Conversely, when interest rates fall, the prices of fixed income securities in the fund will generally rise. The portfolio invests in REIT securities, the value of which can fall for a variety of reasons, such as declines in rental income, fluctuating interest rates, poor property management, environmental liabilities, uninsured damage, increased competition, or changes in real estate tax laws. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.

Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. The Fund acquired the assets and liabilities of Pioneer Select Mid Cap Growth Fund ("the predecessor fund") on June 7, 2013 ("the reorganization"). As a result of the reorganization, the predecessor fund's performance and financial history became the performance and financial history of the Fund. The predecessor fund did not offer Class R shares. Accordingly, the performance of Class R shares of the Fund is the performance of Class A shares of the predecessor fund for periods prior to the reorganization, restated to reflect the higher distribution and service fees of Class R shares, but not other differences in expenses. The predecessor fund was established in connection with the reorganization of Regions Morgan Keegan Select Mid Cap Growth Fund into the predecessor fund on May 15, 2009. The performance shown for Class R shares of the Fund for periods prior to May 15, 2009, is based on the performance of Regions Morgan Keegan Select Mid Cap Growth Fund's Class A shares, which has been restated to reflect differences in any applicable sales charges and the higher distribution and service fees of Class R shares of the Fund (but not differences in expenses). This adjustment has the effect of reducing the previously reported performance of Regions Morgan Keegan Select Mid Cap Growth Fund. A different investment adviser served as the adviser of Regions Morgan Keegan Select Mid Cap Growth Fund.

This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value (divided by) $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Select Mid Cap Growth Fund Based on actual returns from June 1, 2014 through November 30, 2014. ------------------------------------------------------------------------------------------ Share Class A C R Y ------------------------------------------------------------------------------------------ Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 6/1/14 ------------------------------------------------------------------------------------------ Ending Account $1,062.55 $1,058.00 $1,060.12 $1,064.41 Value (after expenses) on 11/30/14 ------------------------------------------------------------------------------------------ Expenses Paid $ 5.64 $ 9.85 $ 7.69 $ 3.93 During Period* ------------------------------------------------------------------------------------------ * Expenses are equal to the Fund's annualized net expense ratio of 1.09%, 1.91% 1.49% and 0.76% for Class A, Class C, Class R and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period). Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 15 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher. Expenses Paid on a $1,000 Investment in Pioneer Select Mid Cap Growth Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from June 1, 2014 through November 30, 2014. ----------------------------------------------------------------------------------------- Share Class A C R Y ----------------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 6/1/14 ----------------------------------------------------------------------------------------- Ending Account $1,019.60 $1,015.49 $1,017.60 $1,021.26 Value (after expenses) on 11/30/14 ----------------------------------------------------------------------------------------- Expenses Paid $ 5.52 $ 9.65 $ 7.54 $ 3.85 During Period* ----------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.09%, 1.91% 1.49% and 0.76% for Class A, Class C, Class R and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period). 16 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 Schedule of Investments | 11/30/14 ----------------------------------------------------------------------------------- Shares Value ----------------------------------------------------------------------------------- COMMON STOCKS -- 99.2% ENERGY -- 5.0% Oil & Gas Exploration & Production -- 4.0% 427,729 Cabot Oil & Gas Corp. $ 14,132,166 68,442 Cimarex Energy Co. 7,182,988 494,267 Goodrich Petroleum Corp.* 2,990,315 120,634 Gulfport Energy Corp.* 5,757,861 613,698 Memorial Resource Development Corp.* 13,255,877 193,356 Rice Energy, Inc. 4,814,564 -------------- $ 48,133,771 ----------------------------------------------------------------------------------- Oil & Gas Refining & Marketing -- 0.2% 23,467 Tesoro Corp. $ 1,798,042 ----------------------------------------------------------------------------------- Oil & Gas Storage & Transportation -- 0.8% 248,127 Boardwalk Pipeline Partners LP* $ 4,094,096 78,991 SemGroup Corp. 5,844,544 -------------- $ 9,938,640 -------------- Total Energy $ 59,870,453 ----------------------------------------------------------------------------------- MATERIALS -- 3.8% Commodity Chemicals -- 1.1% 115,807 Methanex Corp. $ 5,982,590 114,889 Westlake Chemical Corp. 7,306,940 -------------- $ 13,289,530 ----------------------------------------------------------------------------------- Specialty Chemicals -- 1.1% 197,585 Flotek Industries, Inc.* $ 3,848,956 71,043 RPM International, Inc. 3,388,751 62,685 WR Grace & Co.* 6,022,148 -------------- $ 13,259,855 ----------------------------------------------------------------------------------- Construction Materials -- 1.0% 76,101 Eagle Materials, Inc. $ 6,269,961 53,693 Martin Marietta Materials, Inc. 6,445,308 -------------- $ 12,715,269 ----------------------------------------------------------------------------------- Metal & Glass Containers -- 0.3% 124,436 Berry Plastics Group, Inc.* $ 3,601,178 ----------------------------------------------------------------------------------- Paper Products -- 0.3% 104,536 KapStone Paper and Packaging Corp. $ 3,122,490 -------------- Total Materials $ 45,988,322 ----------------------------------------------------------------------------------- CAPITAL GOODS -- 4.5% Aerospace & Defense -- 0.5% 70,236 B/E Aerospace, Inc.* $ 5,469,277 ----------------------------------------------------------------------------------- Construction & Engineering -- 0.1% 56,981 Quanta Services, Inc.* $ 1,737,920 ----------------------------------------------------------------------------------- The accompanying notes are an integral part of these financial statements.

The accompanying notes are an integral part of these financial statements. Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 33 Notes to Financial Statements | 11/30/14 1. Organization and Significant Accounting Policies Pioneer Select Mid Cap Growth Fund (the Fund) is one of two portfolios comprising Pioneer Series Trust II (the Trust), a Delaware statutory trust. The Fund is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Fund acquired the assets and liabilities of Pioneer Select Mid Cap Growth Fund (the "predecessor fund"), a series of Pioneer Series Trust I on June 7, 2013. The predecessor fund was the accounting survivor of the reorganization. Accordingly, the predecessor fund's performance and financial history became the performance and financial history of the Fund. The financial highlights and shareholder activity, as reflected in the Statement of Changes in net assets, have been adjusted to reflect the conversion ratios used for the reorganization of the Fund with the predecessor fund. Prior to the reorganization, the Fund was named Pioneer Growth Opportunities Fund. The investment objective of the Fund is long-term capital growth. During the periods covered by this report, the Fund offered five classes of shares designated as Class A, Class B, Class C, Class R and Class Y shares. The predecessor fund did not offer Class B shares or Class R shares. Accordingly, financial reporting for Class B shares and Class R shares commenced on June 7, 2013, and no financial information has been presented for Class B shares or Class R shares for prior periods. The Fund ceased to offer Class B shares on November 10, 2014. Class B shares were converted to Class A shares as of the close of business on November 10, 2014. Each class of shares represents an interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different rates of class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends from net investment income earned by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class has exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the 34 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities that have traded on an exchange are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are valued at the mean between the last bid and asked prices. Shares of money market mutual funds are valued at such funds' net asset value. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Securities for which independent pricing services are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued by a fair valuation team comprised of certain personnel of Pioneer Investment Management, Inc. (PIM), the Fund's investment adviser, pursuant to procedures adopted by the Fund's Board of Trustees. PIM's fair valuation team uses fair value methods approved by the Valuation Committee of the Board of Trustees. PIM's fair valuation team is responsible for monitoring developments that may impact fair valued securities and for discussing and assessing fair values on an ongoing basis, and at least quarterly, with the Valuation Committee of the Board of Trustees. Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Examples of a significant event might include political or economic news, corporate restructurings, natural Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 35 disasters, terrorist activity or trading halts. Thus, the valuation of the Fund's securities may differ significantly from exchange prices and such differences could be material. At November 30, 2014, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services or broker-dealers). B. Investment Income and Transactions Dividend income is recorded on the ex-dividend date except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. C. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no provision for federal income taxes is required. As of November 30, 2014, the Fund did not accrue any interest or penalties with respect to uncertain tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax returns filed within the prior three years are subject to examination by Federal and State tax authorities. The amount and character of income and capital gain distributions to shareowners are determined in accordance with federal income tax rules, which may differ from U.S. generally accepted accounting principles. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences. At November 30, 2014, the Fund reclassified $62,698 to decrease paid in capital, $6,064,135 to increase undistributed net investment income and $6,001,437 to decrease accumulated net realized gain on investments and foreign currency transactions to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. 36 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 The tax character of distributions paid during the years ended November 30, 2014 and November 30, 2013 were as follows: ---------------------------------------------------------------------------- 2014 2013 ---------------------------------------------------------------------------- Distributions paid from: Ordinary Income $ 3,202,734 $ 4,565,456 Long-term capital gain 159,324,451 93,604,512 ---------------------------------------------------------------------------- Total $162,527,185 $98,169,968 ============================================================================ The following shows the components of distributable earnings on a federal income tax basis at November 30, 2014: ---------------------------------------------------------------------------- 2014 ---------------------------------------------------------------------------- Distributable earnings: Late Year Post October Loss Deferral $ (3,607,647) Undistributed long-term gain 7,866,417 Net unrealized appreciation 279,658,223 ---------------------------------------------------------------------------- Total $283,916,993 ============================================================================ The difference between book-basis and tax-basis net unrealized appreciation is attributable to the tax deferral of losses on wash sales and the tax basis adjustments on partnerships and other holdings. D. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned $66,418 in underwriting commissions on the sale of Class A shares during the year ended November 30, 2014. E. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on its respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class C and Class R shares of the Fund, respectively (see Note 4). Class Y shares do not pay distribution fees. All expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services are allocated among the classes of shares based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 37 Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time, except that net investment income dividends to Class A, Class C, Class R and Class Y shares can reflect different transfer agent and distribution expense rates. F. Risks At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political or regulatory developments or other risks affecting these industries or sectors. The Fund's prospectus contains unaudited information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. G. Option Writing The Fund may write put and covered call options to seek to increase total return. When an option is written, the Fund receives a premium and becomes obligated to purchase or sell the underlying security at a fixed price, upon the exercise of the option. When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains from investments. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Fund has realized a gain or loss. The Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option. The average value of contracts open during the year ended November 30, 2014 was $8,214. Written put option contracts outstanding at year end are listed at the end of the Fund's schedule of investments. There were no written options outstanding at November 30, 2014. Transactions in written options for the year ended November 30, 2014 are summarized as follows: ------------------------------------------------------------------------------------- Number of Contracts Premium Received ------------------------------------------------------------------------------------- Options open at beginning of period -- $ -- Options opened (787) (125,400) Options exercised -- -- Options closed -- -- Options expired 787 125,400 ------------------------------------------------------------------------------------- Options open at end of period -- $ -- ===================================================================================== 38 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at an annual rate equal to 0.625% of the Fund's average daily net assets up to $500 million, 0.60% of the next $500 million and 0.575% on assets over $1 billion. Prior to June 7, 2013, the Fund paid an annual fee equal to 0.65% of the Fund's average daily net assets. Prior to June 7, 2013, the predecessor fund paid a management fee at an annual rate equal to 0.625% of the predecessor fund's average daily net assets up to $500 million, 0.60% of the next $500 million and 0.575% on assets over $1 billion. For the year ended November 30, 2014, the effective management fee was equivalent to 0.61% of the Fund's average daily net assets. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund as administrative reimbursements. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $101,362 in management fees, administrative costs and certain other reimbursements payable to PIM at November 30, 2014. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the year ended November 30, 2014, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $697,109 Class B 24,003 Class C 107,116 Class R 30,867 Class Y 79,959 -------------------------------------------------------------------------------- Total $939,054 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $226,191 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at November 30, 2014. Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 39 4. Distribution Plan The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A and Class C shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily net assets attributable to Class C shares. The fee for Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class C shares. Pursuant to the Plan, the Fund further pays PFD 0.50% of the average daily net assets attributable to Class R shares for distribution services. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $46,772 in distribution fees payable to PFD at November 30, 2014. The Fund also has adopted a separate service plan for Class R shares (Service Plan). The Service Plan authorizes the Fund to pay securities dealers, plan administrators or other service organizations that agree to provide certain services to retirement plans or plan participants holding shares of the Fund a service fee of up to 0.25% of the Fund's average daily net assets attributable to Class R shares held by such plans. In addition, redemptions of each class of shares (except Class R and Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 12 months of purchase. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%, based on the lower of cost or market value of shares being redeemed. Shares purchased as part of an exchange remain subject to any CDSC that applied to the original purchase of those shares. There is no CDSC for Class R or Class Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended November 30, 2014, CDSCs in the amount of $15,582 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended November 30, 2014, the Fund's expenses were not reduced under such arrangements. 6. Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), participates in a committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund 40 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 may borrow up to the lesser of the amount available under the facility or the limits set for borrowing by the Fund's prospectus and the 1940 Act. The credit facility in effect until February 12, 2014 was in the amount of $215 million. As of February 12, 2014, the facility is in the amount of $240 million. Under such facility, depending on the type of loan, interest on borrowings is payable at the London Interbank Offered Rate (LIBOR) plus 0.90% (0.85% as of February 12, 2014) on an annualized basis, or the Alternate Base Rate, which is the greater of (a) the facility's administrative agent's daily announced prime rate on the borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing date and (c) 2% plus the overnight Euro dollar rate on the borrowing date. The Funds pay an annual commitment fee to participate in a credit facility. The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the year ended November 30, 2014, the Fund had no outstanding borrowings. 7. Reorganization Information On June 7, 2013 ("Closing Date"), the predecessor fund was reorganized with the Fund. The purpose of this transaction was to combine two funds (managed by PIM) with similar investment objectives and strategies. This tax-free reorganization was accomplished by exchanging the assets and liabilities of the predecessor fund for shares of the Fund. Shareowners holding Class A, Class C and Class Y shares of the predecessor fund received Class A, Class C and Class Y shares of the Fund, respectively, in the reorganization. The predecessor fund did not offer Class B shares* or Class R shares. Financial reporting for Class B shares and Class R shares commenced on June 7, 2013. The investment portfolio of the predecessor fund, with an aggregate value of $552,334,360 and an identified cost of $442,091,974 at June 7, 2013, was the principal asset acquired by the Fund. For financial reporting purposes, assets received and shares issued by the Fund were recorded at net asset value, however, the cost basis of the investments received from the predecessor fund was carried forward to align ongoing reporting of the Fund's realized and unrealized gains and losses with amounts distributable to shareowners for tax reporting purposes. The Fund was the legal survivor of the reorganization. The predecessor fund was the accounting survivor of the reorganization. Accordingly, the predecessor fund's performance and financial history became the performance and financial history of the Fund. Prior to the reorganization, the Fund was named Pioneer Growth Opportunities Fund. * Class B shares of the Fund converted to Class A shares on November 10, 2014. See Note 9.

Change in Independent Registered Public Accounting Firm The Board of Trustees of the Fund, with the approval and recommendation of the Audit Committee, appointed Deloitte & Touche LLP to serve as the Fund's independent registered public accounting firm for the fiscal year ending November 30, 2014. Deloitte & Touche LLP replaces Ernst & Young LLP, which resigned as the Fund's independent registered public accounting firm, effective upon completion of the audit of the Fund's financial statements for the fiscal year ended November 30, 2013. During the periods that Ernst & Young LLP served as the Fund's independent registered public accounting firm, including the Fund's two most recent fiscal years ending November 30, 2013 and November 30, 2012, Ernst & Young LLP's reports on the financial statements of the Fund have not contained an adverse opinion or disclaimer of opinion and have not been qualified or modified as to uncertainty, audit scope or accounting principles. Further, there have been no disagreements with Ernst & Young LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Ernst & Young LLP would have caused Ernst & Young LLP to make reference to the subject matter of the disagreement in connection with its report on the financial statements. In addition, there have been no reportable events of the kind described in Item 304 (a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934. 10. Conversion of Class B Shares As of the close of business on November 10, 2014 (the "Conversion Date"), all outstanding Class B shares of the Fund were converted to Class A shares. Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 43 Report of Independent Registered Public Accounting Firm To the Board of Trustees of Pioneer Series Trust II and Shareowners of Pioneer Select Mid Cap Growth Fund: -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer Select Mid Cap Growth Fund (the "Fund") (one of two portfolios comprising Pioneer Series Trust II (the Trust)), as of November 30, 2014, and the related statements of operations and changes in net assets, and the financial highlights for year then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audit. The statement of changes in net assets of the Fund for the year ended November 30, 2013, and the financial highlights for the years ended November 30, 2013, 2012, 2011, and 2010 were audited by other auditors. Those auditors expressed an unqualified opinion on those financial statements and financial highlights in their report dated January 24, 2014. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of November 30, 2014, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audit provides a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Select Mid Cap Growth Fund as of November 30, 2014, and the results of its operations, the changes in its net assets, and the financial highlights for the year then ended, in conformity with accounting principles generally accepted in the United States of America. /s/ Deloitte & Touche LLP Boston, Massachusetts January 26, 2015 44 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer Select Mid Cap Growth Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. In order for PIM to remain the investment adviser of the Fund, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement for the Fund. The contract review process began in January 2014 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. Contract review materials were provided to the Trustees in March 2014 and July 2014. Supplemental contract review materials were provided to the Trustees in September 2014. In addition, the Trustees reviewed and discussed the Fund's performance at regularly scheduled meetings throughout the year, and took into account other information related to the Fund provided to the Trustees at regularly scheduled meetings, in connection with the review of the Fund's investment advisory agreement. In March 2014, the Trustees, among other things, discussed the memorandum provided by Fund counsel that summarized the legal standards and other considerations that are relevant to the Trustees in their deliberations regarding the renewal of the investment advisory agreement, and reviewed and discussed the qualifications of the investment management teams, as well as the level of investment by the Fund's portfolio managers in the Fund. In July 2014, the Trustees, among other things, reviewed the Fund's management fee and total expense ratios, the financial statements of PIM and its parent companies, the profitability analyses provided by PIM, and possible economies of scale. The Trustees also reviewed the profitability of the institutional business of PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer"), as compared to that of PIM's fund management business, and considered the differences between the fees and expenses of the Fund and the fees and expenses of Pioneer's institutional accounts, as well as the different services provided by PIM to the Fund and by Pioneer to the institutional accounts. The Trustees further considered contract review materials in September 2014. At a meeting held on September 16, 2014, based on their evaluation of the information provided by PIM and third parties, the Trustees of the Fund, including the Independent Trustees voting separately, unanimously approved the renewal of the investment advisory agreement for another year. In considering the renewal of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. In all quintile rankings referred to throughout this Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 45 disclosure, first quintile is most favorable to the Fund's shareowners. The Trustees did not identify any single factor as the controlling factor in determining to approve the renewal of the agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by PIM to the Fund, taking into account the investment objective and strategy of the Fund. The Trustees reviewed the terms of the investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also reviewed the amount of non-Fund assets managed by the portfolio managers of the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees noted the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund In considering the Fund's performance, the Trustees regularly review and discuss analysis and data prepared by PIM and information comparing the Fund's performance with the performance of its peer group of funds as classified by each of Morningstar, Inc. (Morningstar) and Lipper, and with the performance of the Fund's benchmark index. They also discuss the Fund's performance with PIM on a regular basis. The Trustees confirmed that these regular reviews and discussions were factored into the Trustees' deliberations concerning the renewal of the advisory agreement. For purposes of their contract renewal deliberations, the Trustees considered the discussions held throughout the year regarding the Fund's performance and the performance results of the Fund over various time periods, including the Fund's 46 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 performance results for periods ended June 30, 2014. The Trustees indicated that the Fund's performance was satisfactory and supported the renewal of the investment advisory agreement. Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of its peer group of funds as classified by Morningstar and also to the expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2014 was in the first quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees also considered the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels. The Trustees considered that the expense ratio of the Fund's Class A shares for the twelve months ended June 30, 2014 was in the second quintile relative to its Morningstar peer group and in the first quintile relative its Strategic Insight peer group, in each case for the comparable period. The Trustees considered the impact of transfer agency, sub-transfer agency, and other non-management fee expenses on the expense ratios of the Fund. The Trustees noted that they separately review the Fund's transfer agency, sub-transfer agency and intermediary arrangements. The Trustees reviewed management fees charged by Pioneer to institutional and other clients, including publicly offered European funds sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory capacity), and unaffiliated foreign and domestic separate accounts. The Trustees also considered PIM's costs in providing services to the Fund and Pioneer's costs in providing services to the other clients and considered the differences in management fees and profit margins for Fund and non-Fund services. In evaluating the fees associated with Pioneer's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and client accounts. The Trustees noted that, in some instances, the fee rates for those clients were lower than the management fee for the Fund and considered that, under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and activities related to compliance and the extensive regulatory and tax regimes to Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 47 which the Fund is subject. The Trustees also considered the different entrepreneurial risks associated with PIM's management of the Fund and Pioneer's management of the other client accounts. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees noted the breakpoints in the management fee schedule. The Trustees recognize that economies of scale are difficult to identify and quantify, and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Fund. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons including reductions in expenses. The Trustees concluded that economies of scale, if any, were being appropriately shared with the Funds. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. Pioneer is the principal U.S. asset management business of Pioneer Global 48 Pioneer Select Mid Cap Growth Fund | Annual Report | 11/30/14 Asset Management, the worldwide asset management business of UniCredit Group, which manages over $150 billion in assets (including the Funds). Pioneer and the Funds receive reciprocal intangible benefits from the relationship, including mutual brand recognition and, for the Funds, direct and indirect access to the resources of a large global asset manager. The Trustees concluded that any such benefits received by Pioneer as a result of its relationship with the Funds were reasonable and their consideration of the advisory agreement between the Fund and PIM and the fees thereunder were unaffected by Pioneer's possible receipt of any such intangible benefits. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment advisory agreement for the Fund.

PIONEER FUNDS APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES PROVIDED BY THE INDEPENDENT AUDITOR SECTION I - POLICY PURPOSE AND APPLICABILITY The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Pioneer Investment Management, Inc ("PIM"), the audit committee and the independent auditors. The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence. Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii). In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived. Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.
