President's Letter

Dear Shareowner,

Today's market environment presents numerous opportunities as well as challenges
for investors. 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

                 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.

Please refer to the Schedule of Investments on pages 17-25 for a full listing of
Fund securities.

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.

These risks may increase share price volatility.

Before investing, consider the product's investment objectives, risks, charges
and expenses. Contact your advisor or Pioneer Investments for a prospectus or

Index Definition
--------------------------------------------------------------------------------
The Russell Midcap Growth Index is an unmanaged index that measures the
performance of U.S. mid-cap growth stocks. Index returns are calculated monthly,
assume reinvestment of dividends and, unlike Fund returns, do not reflect any
fees, expenses or sales charges. It is not possible to invest directly in an
index.

The index defined here pertains to the "Value of $10,000 Investment" and "Value
of $5 Million Investment" charts on pages 11-14.

*   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.
    Historical per share amounts prior to June 7, 2013 have been adjusted to
    reflect the conversion ratios used for the reorganization. The predecessor
    fund did not offer Class R Shares. Financial reporting for Class R shares
    commenced on June 7, 2013.

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. 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
performance of Class A shares of the Fund is the performance of Class A shares
of the predecessor fund for periods prior to the reorganization, and has not
been restated to reflect any 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 of Class A shares of the predecessor fund for
periods prior to May 15, 2009, includes 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 (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.

result of the reorganization, the predecessor fund's performance and financial

Class R shares of the Fund is the performance of Class A shares of the

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

Class Y shares are not subject to sales charges and are available for limited
groups of eligible investors, including institutional investors. All results are
historical and assume the reinvestment of dividends and capital gains. Other
share classes are available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. 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
performance of Class Y shares of the Fund is the performance of Class Y shares
of the predecessor fund for periods prior to the reorganization, and has not
been restated to reflect any 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 of Class Y shares of the predecessor fund for
periods prior to May 15, 2009, includes the performance of Regions Morgan Keegan
Select Mid Cap Growth Fund's Class I shares, which has been restated to reflect
differences in any applicable sales charges (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.

Comparing Ongoing Fund Expenses

As a shareowner in the Fund, you incur two types of costs:

(1) ongoing costs, including management fees, distribution and/or service
    (12b-1) fees, and other Fund expenses; and

(2) transaction costs, including sales charges (loads) on purchase payments.

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 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).

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.

Purchases and sales of securities (excluding temporary cash investments) for the
year ended November 30, 2014 aggregated $1,240,230,421 and $1,352,751,675,
respectively.

Various inputs are used in determining the value of the Fund's investments.
These inputs are summarized in the three broad levels listed below.

    Level 1 -- quoted prices in active markets for identical securities.

    Level 2 -- other significant observable inputs (including quoted prices for
               similar securities, interest rates, prepayment speeds, credit
               risk, etc.) See Notes to Financial Statements -- Note 1A.

    Level 3 -- significant unobservable inputs (including the Fund's own
               assumptions in determining fair value of investments) See Notes
               to Financial Statements -- Note 1A.

Generally, equity securities are categorized as Level 1, fixed income securities
and senior loans as Level 2 and securities valued using fair value methods
(other than prices supplied by independent pricing services or broker-dealers)
as Level 3.

                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.

    The tax character of distributions paid during the years ended November 30,
    2014 and November 30, 2013 were as follows:



    ----------------------------------------------------------------------------
                                                             2014           2013

    ----------------------------------------------------------------------------
         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:

    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:

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,

reimbursements payable to PIM at November 30, 2014.

3. Transfer Agent

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.

Assuming the Reorganization had been completed on December 1, 2012, the pro
forma results of operations for the fiscal year ended November 30, 2013, were as
follows:

Because the combined investment portfolios have been managed as a single
integrated portfolio since the reorganization was completed, it is not practical
to separate the amounts of revenue and earnings of the Fund that have been
included in the Statements of Operations since the Reorganization was
consummated.

8. Additional Disclosures about Derivative Instruments and Hedging Activities

ended November 30, 2014 was as follows:

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.

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.

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.

  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.
