President's Letter

Dear Shareowner,

When we look into 2014, we foresee U.S. economic growth matching or exceeding
2013 levels. While unemployment remains high, employment has been rising
steadily. Consumer incomes, savings, wealth, and debt-servicing capacity have
been solid buttresses for the recovering housing and auto industries. Industrial
activity is growing only moderately, but current corporate profits are generally
solid and balance sheets appear able to support needed capital spending and
dividend* payouts. Tax hikes, spending restraint and a better economy have
meaningfully cut the federal budget deficit. A modestly improving European
economy, continuing economic improvement in Japan, and a "soft landing" of 7%
growth in China appear likely to result in improving global growth in 2014,
further supporting the U.S. economy. In addition, we feel that continuing slack
in labor markets and capacity utilization offers the potential for continuing
growth without bottlenecks and rising inflation, making it possible for the
Federal Reserve (the Fed) to continue its accommodative monetary policies.

After observing the strengthening economic trends, the Fed decided in December
2013 to start scaling back its QE (quantitative easing) program, but also said
that short-term interest rates are likely to remain near zero for some time to
come, given that inflation remains subdued and unemployment remains high.

The U.S. government's partial shutdown in October 2013 rattled the markets to a
degree, but does not appear to have had a significant negative impact on the
economy or capital markets. As the year drew to a close, leaders in Washington
reached a bipartisan budget agreement that establishes top-line government
spending levels for the next two fiscal years, a move which should help to
defuse the threat of another shutdown. That certainly was welcome news for
investors who had grown weary of infighting in Washington and wary of the risks
the policy uncertainty caused.

There are certainly risks and uncertainties facing the global economy as we head
into 2014. The European economy, while improving, remains weak, the Japanese
economy faces a tax hike this spring, and a number of emerging market countries
are experiencing difficulties. There are also geopolitical worries abroad and
the aforementioned political fights at home. While most of the widely recognized
risks we've outlined may already be "priced into" the market, we believe
investors should continue to expect market volatility.

goals and work together to develop an investment strategy that meets your
individual needs, keeping in mind that there is no single best strategy that

Portfolio Management Discussion | 12/31/13

In the following interview, Matthew Troxell of AEW Capital Management, L.P.,
sub-adviser for Pioneer Real Estate Shares, discusses the market environment for
real estate-related investments and the Fund's performance during the 12-month
period ended December 31, 2013.

Q   How would you describe the investment environment for real estate
    investments in 2013?

A   While real estate investment trusts (REITs) turned in positive performance
    during the 12-month period, the asset class underwent a significant
    correction in the second and third quarters of 2013 as investors began to
    once again price risk into the market. The correction was primarily due to
    the Federal Reserve's (the Fed's) announcement in May which hinted at an
    eventual winding down of its stimulative quantitative easing (QE)
    bond-buying program, and the Fed's decision in December to actually begin
    tapering QE in January 2014. Interest-rate-sensitive investments, including
    REITs, struggled in the aftermath of the Fed's May announcement, as their
    prices declined in anticipation of higher rates. Unlike bonds, however,
    which saw the end of a five-year rally during the period, the ability of
    REITs to grow earnings and dividends in an expanding economy aided their
    overall performance.

Q   How did Pioneer Real Estate Shares perform during the 12-month period ended
    December 31, 2013?

A   Class A shares of Pioneer Real Estate Shares returned 1.14% at net asset
    value during the 12-month period ended December 31, 2013, while the Fund's
    benchmark, the Morgan Stanley Capital International (MSCI) U.S. REIT Index
    (the MSCI Index)(1), returned 2.47%. During the same period, the average
    return of the 259 mutual funds in Morningstar's Real Estate Funds category
    was 1.55%, and the average return of the 242 mutual funds in Lipper's Real
    Estate Funds category was 1.72% for the same 12-month period.

Q   Did your search for attractive investment opportunities lead to any notable
    shift in the Fund's strategy or sector allocations during the 12-month
    period ended December 31, 2013?

A   Heading into 2013, the Fund's portfolio was tilted toward undervalued
    companies with stronger balance sheets and higher-quality assets in top-tier
    markets that we thought were best positioned to grow earnings as the economy
    recovered. We also thought that the companies' balance sheets would be
    better positioned for a rising interest-rate environment. Consequently, when
    the Fed made its announcement in May about a possible QE taper, the Fund's
    portfolio already had a more defensive bias than many of its peers, which
    was beneficial for performance during the REIT market correction, although
    the positioning did hold back performance when the markets were rallying
    prior to May event.

Q   Which of your investment strategies and/or individual portfolio holdings
    detracted most from the Fund's performance during the 12-month period ended
    December 31, 2013?

A   We attribute the Fund's underperformance relative to the MSCI Index during
    the period to negative stock selection results in the industrial, health
    care, and, in particular, the apartment REIT sector.

    The positions that detracted the most from the Fund's benchmark-relative
    performance during the 12-month period included Camden Property Trust,
    AvalonBay Communities, and American Campus Communities. The apartment sector
    lagged the MSCI Index during the period, turning in negative performance for
    2013, as slowing rent growth and the prospect of higher interest rates
    weighed on the sector. Our decision to overweight the Fund's portfolio to
    these three apartment REITs further detracted from relative performance
    during the 12-month period.

Q   Which of your investment strategies and/or individual portfolio holdings
    benefited the Fund's performance during the 12-month period ended December
    31, 2013?

A   Sector allocation strategies were positive for the Fund's relative
    performance during the period, most notably our decision to hold an
    underweight exposure in the portfolio to the underperforming health care
    sector, and to overweight the outperforming diversified and storage sectors.

    The top individual contributors to the Fund's benchmark-relative performance
    during the 12-month period included overweight positions in the
    outperforming Forest City Enterprises, Extra Space Storage, and Host Hotels
    & Resorts. Forest City Enterprises continued to reduce its debt during the
    year, which favorably affected its balance sheet. Toward the end of 2013,
    the company announced that it was forming a joint-venture

                         Pioneer Real Estate Shares | Annual Report | 12/31/13 5


    partnership for two large development projects, which removed a great deal
    of development risk that had been pressuring the stock. Within the storage
    sector, Extra Space Storage posted stronger-than-expected earnings results
    throughout 2013. Host Hotels & Resorts benefited during the period from the
    continued improvement in hotel market fundamentals.

Q   What is your outlook for REITs in 2014?

A   During the fourth quarter of 2013, the outlook for REITs firmed
    considerably when the political backdrop in Washington improved and better
    economic data allowed the Fed to take the first steps toward normalizing
    monetary policy by reducing its bond purchases (beginning in January). Thus,
    the headline risk has diminished, removing a barrier to business confidence
    as well as improving considerably the baseline expectations for U.S.
    economic performance going into 2014.

    With the overall economic outlook improving, however, higher interest rates
    become more of a risk factor. In our experience, how fast and how far
    interest rates rise has been a key indicator of where REIT values are
    headed. Large, rapid increases in interest rates would clearly be a negative
    for REIT values - not to mention for the bond market in general. In our
    view, such an outcome is unlikely, given dormant inflation, the likelihood
    that such an abrupt shock could lead to a recession, and new leadership at
    the Fed, in the person of Janet Yellin, who has been a proponent of the
    central bank's stimulative bond-buying campaign aimed at bringing down
    interest rates and encouraging economic growth. Rather, we believe a
    moderate pace of rate increases to be the more likely scenario, and we think
    that has already been priced into the market.

    Given the 2013 correction in U.S. REIT prices, valuations have reached fair
    levels, in our view, and are more in line with historical averages after
    several years of being elevated. Consequently, we think the asset class
    appears more appealing than it has since the beginning of 2009, roughly five
    years ago. Furthermore, the real estate sector's underlying fundamentals
    continue to improve, and we believe that the resulting higher property
    incomes should offset any further upward move in capitalization rates, which
    represents the ratio of net operating income to the value of the property.
    We think that should allow the sector to deliver positive results for
    investors in 2014. And finally, vacancy rates declined considerably in 2013,
    most notably in the office, industrial, and shopping center markets, while
    demand in multi-family markets outpaced supply. Thus, supply risk continues
    to be minimal, with only the apartment sector reverting back to long-term
    construction averages.

6 Pioneer Real Estate Shares | Annual Report | 12/31/13


As 2014 begins, we are seeing rents moving up in all property types, and some
longer-lease property types should soon transition to an environment where
leases will be signed at higher rents than at current levels - a substantial
positive for net operating income. Thus, with U.S. job growth expected to
continue improving and the Fed transitioning to a more normalized monetary
policy in 2014, we think REIT earnings should continue to grow and contribute to
investment results. This year, those results will likely be driven less by
macroeconomic factors and more by leasing fundamentals, balance sheet quality,
and capital allocation acumen at the individual company and property sector
levels.

Please refer to the Schedule of Investments on pages 17-19 for a full listing of
Fund securities.

The Fund 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.

The Fund invests in a limited number of securities and, as a result, the Fund's
performance may be more volatile than the performance of other funds holding
more securities.

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.

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 or sectors.

These risks may increase share price volatility.

Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

Any information in this shareholder report regarding market or economic trends
or the factors influencing the Fund's historical or future performance are

Index Definition
--------------------------------------------------------------------------------
The MSCI U.S. REIT Index is an unmanaged, widely used index comprising a broad
representation of the most actively traded real estate trusts, and is designed
to be a measure of real estate equity performance. 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.

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.

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.

Comparing Ongoing Fund Expenses (continued)

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 December 31, 2013 aggregated $23,574,433 and $25,232,941,
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) as Level 3.

The following is a summary of the inputs used as of December 31, 2013, in
valuing the Fund's investments:

Notes to Financial Statements | 12/31/13

1. Organization and Significant Accounting Policies

Pioneer Real Estate Shares (the Fund) is a Delaware statutory trust registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objective of the Fund is to seek long-term
growth of capital. Current income is a secondary objective.

The Fund offers four classes of shares designated as Class A, Class B, Class C
and Class Y shares. Effective as of the close of business on December 31, 2009,
Class B shares are no longer offered to new or existing shareholders, except
that dividends and/or capital gain distributions may continue to be reinvested
in Class B shares, and shareholders may exchange their Class B shares for Class
B shares of other Pioneer funds, as permitted by existing exchange privileges.
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. Class B shares convert to Class A shares approximately eight years after
the date of purchase.

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 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:

28 Pioneer Real Estate Shares | Annual Report | 12/31/13


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. Short-term fixed income securities
    with remaining maturities of sixty days or less generally are valued at
    amortized cost. 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
    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 December 31, 2013, there were no securities that were valued using fair
    value methods (other than securities that were valued using prices supplied
    by independent pricing services).

                        Pioneer Real Estate Shares | Annual Report | 12/31/13 29


    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, including interest on
    income bearing cash accounts, 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.

B.  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 December 31, 2013, the Fund did not accrue any interest or penalties
    related 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 remain 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.

    During the year ended December 31, 2013, a capital loss carryforward of
    $6,306,554 was utilized to offset net realized gains by the Fund.

    The tax character of distributions paid during the years ended December 31,
    2013 and December 31, 2012 was as follows:



    ----------------------------------------------------------------------------
                                                       2013                 2012
    ----------------------------------------------------------------------------
                                                                
    Distributions paid from:
    Ordinary income                              $1,286,381           $2,324,579
    Long-term capital gain                        1,449,677                   --

    ============================================================================


30 Pioneer Real Estate Shares | Annual Report | 12/31/13


    The following shows the components of distributable earnings on a federal
    income tax basis at December 31, 2013:



    ----------------------------------------------------------------------------
                                                                            2013
    ----------------------------------------------------------------------------
                                                                  
    Distributable Earnings:
    Undistributed long-term capital gain                             $ 1,239,344
    Net unrealized appreciation                                       53,485,771
    ----------------------------------------------------------------------------
         Total                                                       $54,725,115
    ============================================================================


    The difference between book-basis and tax-basis net unrealized appreciation
    is attributable to the tax deferral of losses on wash sales.

C.  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 $14,947 in underwriting commissions on the sale of Class A shares
    during the year ended December 31, 2013.

D.  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 B and Class C 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).

    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 B, Class C and Class Y shares
    can reflect different transfer agent and distribution expense rates.

                        Pioneer Real Estate Shares | Annual Report | 12/31/13 31


E.  Risks

    Because the Fund may invest a substantial portion of its assets in Real
    Estate Investment Trusts (REITs), the Fund may be subject to certain risks
    associated with direct investments in REITs. REITs may be affected by
    changes in the value of their underlying properties and by defaults of their
    borrowers or tenants. REITs depend generally on their ability to generate
    cash flow to make distributions to shareowners, and certain REITs have self-
    liquidation provisions by which mortgages held may be paid in full and
    distributions of capital returns may be made at any time. In addition, the
    performance of a REIT may be affected by its failure to qualify for tax-free
    pass through of income under the Internal Revenue Code or its failure to
    maintain exemption from registration under the Investment Company Act of
    1940. 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.

F.  Repurchase Agreements

    With respect to repurchase agreements entered into by the Fund, the value of
    the underlying securities (collateral), including accrued interest, is
    required to be equal to or in excess of the repurchase price. The collateral
    for all repurchase agreements is held in safekeeping in the customer-only
    account of the Fund's custodian or a subcustodian of the Fund. PIM is
    responsible for determining that the value of the collateral remains at
    least equal to the repurchase price.

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. Management fees are calculated daily at the annual rate of 0.80% of
the Fund's average daily net assets up to $1 billion and 0.75% on assets over $1
billion. For the year ended December 31, 2013, the effective management fee
(excluding waivers and/or assumption of expenses) was equal to 0.80% of the
Fund's daily net assets. PIM pays a portion of the fee it receives from the Fund
to AEW Capital Management, L.P. as compensation for sub-advisory services to the
Fund.

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
$13,495 in management fees, administrative costs and certain other
reimbursements payable to PIM at December 31, 2013.

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 December 31, 2013, such out-of-pocket expenses by class of shares
were as follows:

--------------------------------------------------------------------------------
  Total                                                                 $133,316
================================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $32,635 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at December 31, 2013.

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, Class B 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 B and Class C shares. The fee for
Class B and 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 B and Class C
shares. Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $3,763 in distribution fees payable to PFD at December 31, 2013.

In addition, redemptions of each class of shares (except 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. Class B shares that are redeemed within five years
of purchase are subject to a CDSC at declining rates beginning at 4.00%, based
on the lower of cost or market value of shares being redeemed. Redemptions of
Class C shares within 12 months of purchase are subject to a CDSC of 1.00%,
based on the lower of cost or market value of shares being

                        Pioneer Real Estate Shares | Annual Report | 12/31/13 33


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 Y shares. Proceeds from the CDSC are paid to PFD. For the year ended
December 31, 2013, CDSC in the amount of $4,343 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 December 31, 2013, 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 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 during the fiscal year ended December 31, 2013 was in
the amount of $215 million. Under such facility, depending on the type of loan,
interest on borrowings was payable at LIBOR plus 0.90% on an annualized basis,
or the Alternate Base Rate, which was 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 December 31, 2013, the Fund had no borrowings
under a credit facility.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareowners of Pioneer Real Estate Shares:
--------------------------------------------------------------------------------

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Real Estate Shares (the "Fund"), as of
December 31, 2013, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period 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
audits.

We conducted our audits 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. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits 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 and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of December 31, 2013, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. We believe that our audits provide 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 Real Estate Shares at December 31, 2013, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and financial highlights for each of the five years in
the period then ended, in conformity with U.S. generally accepted accounting
principles.

                                                           /s/ Ernst & Young LLP

Approval of Investment Advisory and Sub-Advisory Agreements

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Real Estate Shares (the Fund) pursuant to an investment advisory
agreement between PIM and the Fund. PIM has retained AEW Capital Management,
L.P. (the Sub-Adviser) to serve as the sub-adviser to the Fund pursuant to a
sub-advisory agreement between PIM and the sub-adviser. In order for PIM and
the Sub-Adviser to remain the investment adviser and sub-adviser of the Fund,
respectively, the Trustees of the Fund must determine annually whether to renew
the investment advisory agreement and the sub-advisory agreement for the Fund.

The contract review process began in March 2013 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the process.
In July 2013, the Trustees approved the format of the contract review materials
and submitted their formal request to PIM to furnish information necessary to
evaluate the terms of the investment advisory agreement and the sub-advisory
agreement. The contract review materials were provided to the Trustees in July
2013 and September 2013. After reviewing and discussing the materials, the
Trustees submitted a request for additional information to PIM, and materials
were provided in response to this request. Meetings of the Independent Trustees
of the Fund were held in July, September, and November, 2013 to review and
discuss the contract review materials. In addition, the Trustees took into
account the information related to the Fund provided to the Trustees at
regularly scheduled meetings.

At a meeting held on November 12, 2013, based on their evaluation of the
information provided by PIM, the Sub-Adviser and third parties, the Trustees of
the Fund, including the Independent Trustees voting separately, unanimously
approved the renewal of the investment advisory agreement and the sub-advisory
agreement for another year. In considering the renewal of the investment
advisory agreement and the sub-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
disclosure, first quintile is most favorable to the Fund's shareowners. Thus,
highest relative performance would be first quintile and lowest relative
expenses would also be first quintile. The Trustees did not identify any single
factor as the controlling factor in determining to approve the renewal of the
agreements.

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by each of PIM and the Sub-Adviser to the Fund, taking into
account the investment objective and strategy of the Fund. The Trustees reviewed
the terms of the investment advisory agreement and the sub-advisory agreement.

36 Pioneer Real Estate Shares | Annual Report | 12/31/13


With respect to PIM, the Trustees considered that PIM supervises and monitors
the performance of the Sub-Adviser and the Fund's other 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 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 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.

With respect to the Sub-Adviser, the Trustees considered the Sub-Adviser's
investment approach for the Fund and its research process. The Trustees
considered the resources of the Sub-Adviser and the personnel of the Sub-
Adviser who provide investment management services to the Fund. Based on these
considerations, the Trustees concluded that the nature, extent and quality of
services that had been provided by each of PIM and the Sub-Adviser to the Fund
were satisfactory and consistent with the terms of the investment advisory
agreement and the sub-advisory agreement, respectively.

Performance of the Fund

The Trustees review the Fund's performance on a regular basis, based on analysis
and data prepared by PIM for this purpose and discuss performance issues with
PIM on an ongoing basis. For purposes of their contract renewal deliberations,
the Trustees considered the performance results of the Fund over various time
periods. They reviewed information comparing the Fund's performance with the
performance of its peer group of funds as classified by Morningstar, Inc.
(Morningstar), an independent provider of investment company data, and with the
performance of the Fund's benchmark index. The Trustees considered that the
Fund's annualized total return was in the second quintile of its Morningstar
category for the one, five, and ten year periods ended June 30, 2013, and in the
third quintile of its Morningstar category for the three year period ended June
30, 2013. The Trustees noted the discussions held throughout the year regarding
the Fund's performance and confirmed that those discussions were factored into
the Trustees' deliberations concerning the renewal of the advisory and
sub-advisory agreements. The Trustees concluded that the investment performance
of the Fund was satisfactory.

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

                        Pioneer Real Estate Shares | Annual Report | 12/31/13 37


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 also considered that PIM, not the Fund, paid the
Sub-Adviser pursuant to the sub-advisory agreement. The Trustees evaluated the
fee under the sub-advisory agreement and the portion of the fee under the
investment advisory agreement retained by PIM, and the services provided by the
respective parties under such agreements.

The Trustees considered that the Fund's management fee for the twelve months
ended June 30, 2013 was in the third quintile relative to the management fees
paid by other funds in its Morningstar peer group for the comparable period. The
Trustees also considered the breakpoint in the management fee schedule and the
reduced fee rate above a certain asset level.

The Trustees considered that the Fund's expense ratio for the twelve months
ended June 30, 2013 was in the fourth quintile relative to both its Morningstar
peer group and 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,
and noted the impact of expenses relating to small accounts and omnibus accounts
on transfer and sub-transfer agency expenses generally. 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 PIM and PIM's affiliate,
Pioneer Institutional Asset Management, Inc. (together with PIM, "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 Sub-Adviser and the Fund's
other service providers and activities related to compliance and the extensive
regulatory and tax regimes to 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.

38 Pioneer Real Estate Shares | Annual Report | 12/31/13


The Trustees reviewed management fees charged by the Sub-Adviser to its other
clients. The Trustees noted that the sub-advisory fees paid to the Sub-Adviser
with respect to the Fund were within the range of the fee rates charged by the
Sub-Adviser to its other clients.

The Trustees concluded that the management fee payable by the Fund to PIM, as
well as the fees payable by PIM to the Sub-Adviser, were reasonable in relation
to the nature and quality of the services provided by PIM and the Sub-Adviser 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. The Trustees further
considered the sub-advisory fees received by the Sub-Adviser with respect to the
Fund and the percentage that such fees represented of the Sub-Adviser's overall
revenues. 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 and also that the
percentage that sub-advisory fees represented of the Sub-Adviser's overall
revenues was not unreasonable with respect to the sub-advisory services provided
to the Fund.

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 breakpoint in the management fee schedule. The Trustees recognize that
economies of scale are difficult to identify and quantify, rarely identifiable
on a fund-by-fund basis, 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 particularly, for example during the recent difficult periods for
financial markets, as the level of

                        Pioneer Real Estate Shares | Annual Report | 12/31/13 39


services was maintained notwithstanding a significant decline in PIM's fee
revenues from the Fund. Accordingly, the Trustees concluded that economies of
scale, if any, were being appropriately shared with the Fund.

Other Benefits

The Trustees considered the other benefits to each of PIM and the Sub-Adviser
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. The Trustees considered the intangible benefits to each of PIM
and the Sub-Adviser by virtue of its relationship with the Fund and the other
Pioneer funds. The Trustees concluded that the receipt of these benefits was
reasonable in the context of the overall relationship between each of PIM and
the Sub-Adviser and the Fund.

Conclusion

After consideration of the factors described above as well as other factors, the
Trustees, including all of the Independent Trustees, concluded that each of the
investment advisory agreement between PIM and the Fund and the sub-advisory
agreement between PIM and the Sub-Adviser, including, in each case, the fees
payable thereunder, was fair and reasonable and voted to approve the proposed
renewal of each of the investment advisory agreement and the sub-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.
