President's Letter

Dear Shareowner,

Over the past several years, many investors experienced positive returns across
most major asset classes. However, 2015 was a tale of two markets, with
favorable market conditions in the first half of the year, followed by an abrupt
slowdown and increased volatility beginning in August. The global markets were
challenged by significant economic cross-currents in different geographic
regions and industrial sectors. While the U.S. economy gradually improved,
growth slowed in China. Emerging markets struggled following a decline in
commodity prices, especially oil. While lower energy prices are good for the
consumer, there were ripple effects throughout the global economy.

Against this backdrop, the Standard & Poor's 500 Index rose by just 1.4% in
2015, international equity markets were essentially flat, and emerging market
equities fell sharply. Across U.S. fixed-income sectors, U.S. government and
investment-grade corporate bonds were fairly flat for the year, while high-yield
bonds, as measured by the Bank of America Merrill Lynch Master II High Yield
Index, posted a -4.9% total return.

Entering 2016, we see the U.S. economy growing modestly, against an overall
global economic backdrop that remains fragile and points towards structurally
lower growth. As always in a Presidential election year, political rhetoric has
the potential to impact U.S. sectors such as health care in 2016. Economies
around the world in both developed and emerging markets are experiencing deep
structural change. Geopolitical instability on many fronts, the rising risk of
policy mistakes, and market liquidity issues all increase the possibility of
sharp swings in asset values. In this environment, financial markets remain
vulnerable to unusual levels of volatility. While divergences among regions and
industries is an important theme, we are generally optimistic about the outlook
for the U.S. economy, which we expect will see continued, positive growth led by
a strengthened consumer.

Throughout Pioneer's history, we have believed in the importance of active
management. In periods of market volatility, we believe that the value of active
management is even more compelling. Our experienced and tenured investment teams
focus on identifying value across global markets using proprietary research,
careful risk management, and a long-term perspective. Our ongoing goal is to
produce compelling returns consistent with the stated objectives of our
investment products, and with our shareowners' expectations. We believe our
shareowners can benefit from the experience and tenure of our investment teams
as well as the insights generated from our extensive research process.

2 Pioneer Real Estate Shares | Annual Report | 12/31/15


As always, and particularly during times of market uncertainty, 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.

We greatly appreciate the trust you have placed in us and look forward to
continuing to serve you in the future.

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 12/31/15

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, 2015.

Q    How did the Fund perform during the 12-month period ended December 31,
     2015?

A    Pioneer Real Estate Shares Class A shares returned 4.27% at net asset value
     during the 12-month period ended December 31, 2015, while the Fund's
     benchmark, the Morgan Stanley Capital International (MSCI) U.S. Real Estate
     Investment Trust (REIT) NR Index (the MSCI Index)(1), returned 1.28%.
     During the same period, the average return of the 264 mutual funds in
     Lipper's Real Estate Funds Category was 2.19%, and the average return of
     the 282 mutual funds in Morningstar's Real Estate Funds Category was 2.41%.

Q    How would you describe the market environment for REIT investors during the
     12-month period ended December 31, 2015?

A    While property transaction volume slowed a bit during 2015, real estate
     fundamentals and pricing continued to be strong. Apartment vacancy rates
     were steady, despite substantial construction deliveries during the year,
     as the so-called "Millennial" generation that recently became the nation's
     largest demographic group found jobs and formed households, soaking up new
     supply. Meanwhile, vacancy rates in other property types continued to trend
     downward, albeit slowly.

     On a national level, supply risk was limited outside of apartments and
     senior housing REITs. A few select office, industrial, and hotel markets
     saw meaningful construction, although in most cases, that has been in
     response to very strong demand in those same markets. An important
     exception is oil-sensitive markets, such as Houston, which have been
     deteriorating as substantial new supply runs into weakening demand.

4 Pioneer Real Estate Shares | Annual Report | 12/31/15


     Nationally, rents have been moving up in all property types, and some
     longer-lease property types are transitioning to an environment where new
     lease agreements will command higher rents than the in-place leases signed
     in the aftermath of the global financial crisis. We think that could
     provide a boost to net operating income.

Q    Which investments or strategies aided the Fund's benchmark-relative
     performance during the 12-month period ended December 31, 2015?

A    The Fund's outperformance relative to the MSCI Index during the period
     derived mainly from positive stock selection results and positive sector
     allocation results. In terms of stock selection, benchmark-relative
     performance was strongest in the storage, regional mall, and diversified
     REIT sectors. Positive sector allocation results were due primarily to the
     Portfolio's underweight exposures to the underperforming triple-net-lease
     and health care sectors, and an overweight position in the outperforming
     storage REIT sector.

     Among individual REITs, top contributors to benchmark-relative performance
     during the period included overweight Fund positions in the outperforming
     self-storage company CubeSmart and in apartment REIT Equity Residential, as
     well as a lack of exposure to underperforming diversified company NorthStar
     Realty Finance. Within the storage sector, both demand and supply
     fundamentals remain strong, and CubeSmart reported better-than-expected
     quarterly results throughout the fiscal year as the company continued to
     acquire assets and grow its development pipeline. In the apartment sector,
     Equity Residential continued to post solid quarterly results over the
     12-month period, benefiting from strong lease-up of its development
     pipeline. In the diversified sector, NorthStar is an externally managed
     REIT that owns a portfolio of health care, manufactured housing, and
     net-lease properties. During the period, the company authorized a share
     repurchase program of up to $500 million and spun off NorthStar Realty
     Europe, a pure-play office REIT. The stock underperformed during execution
     of the company's strategy, and the Fund benefited from not owning it.

Q    Which investments or strategies detracted from the Fund's
     benchmark-relative performance results for the 12-month period ended
     December 31, 2015?

A    Stock selection results in the hotel and apartment sectors hurt the Fund's
     benchmark-relative returns the most during the period. Among individual
     names, the top detractors from relative performance included overweight
     portfolio positions in two underperforming hotel REITs, RLJ Lodging Trust
     and Hilton Worldwide, and lack of exposure to the outperforming apartment
     company Essex Property Trust. The hotel sector was the worst performer
     among REITs, by far, during 2015, due to concerns about slowing

                         Pioneer Real Estate Shares | Annual Report | 12/31/15 5


     revenue-per-available-room growth, new supply, and international travel
     worries. As a result, the Fund's overweight positions in RLJ and Hilton
     were drags on performance. We still like the relative value of hotel
     companies, however, and following the correction, we moved the Fund from an
     underweight position to a market-weight position in the sector.

Q    Did you make any adjustments to the Fund's strategy or sector allocations
     during the 12-month period ended December 31, 2015, particularly related to
     the anticipated rising-interest-rate environment?

A    We didn't make any significant changes to the Fund's investment strategy
     during 12-month period. The portfolio continued to be well diversified* by
     property type and geographic region, and our investment process continued
     to focus on security selection within each property sector.

     As always, we sought to construct a portfolio that we believed could help
     the Fund outperform in different economic and market environments. Based on
     property market fundamentals and relative valuations within the REIT
     sector, we increased the Fund's overweight in the regional mall sector
     during the period, with a particular focus on companies with "Class A"
     malls. We also moved the portfolio from an underweight to an overweight
     position in the apartment sector, as fundamentals "re-accelerated" with
     rent growth growing once again. Finally, we decreased the Fund's overweight
     in the storage sector after several quarters of strong outperformance. The
     triple-net-lease and health care sectors remain the portfolio's largest
     underweights relative to the MSCI Index, as their fixed-lease structures
     tend to makes their cash flows the most bond-like, which, in our view,
     could expose both sectors to the price-dampening pressures of a rising-
     interest-rate environment.

Q    Did the Fund invest in any derivative securities during the 12-month period
     ended December 31, 2015?

A    No. We did not engage in any derivatives trading during the period.

Q    What is your outlook for REITs in 2016?

A    We believe the REIT market appears to offer fair valuations as compared
     with other asset classes. At the end of 2015, REITs were trading at a 6%
     discount to their net asset values, and U.S. REIT dividend yields stood at
     3.9%. REIT yield spreads-to-bonds were mixed, however, as they continued to
     trade at wider-than-average spreads to Treasuries (meaning they were
     relatively less expensive than usual), but were further inside corporate
     bond yields, and thus relatively more expensive than normal.

6 Pioneer Real Estate Shares | Annual Report | 12/31/15


     While the REIT market may continue to react nervously to upward moves in
     interest rates over the short term, we believe earnings should support
     ample dividend** growth and help to offset the negative effects of gradual
     interest-rate increases. Going forward, we expect REIT returns to be driven
     more by current yield and improving earnings fundamentals than by
     additional multiples expansion. All told, we expect average cash-flow
     growth for REITs to be in the upper single digits for 2016.

     Given our bottom-up stock selection process and our view of the REIT market
     at the start of 2016, we see the best relative value - and are maintaining
     the Fund's largest overweight positions - in the regional mall, apartment,
     and manufactured home sectors. The portfolio's largest underweight
     exposures relative to the MSCI Index as of period-end were to the
     triple-net-lease, health care, and office sectors.

Please refer to the Schedule of Investments on pages 15-17 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.

Before investing, consider the product's investment objectives, risks, charges
and expenses. Contact your advisor or Pioneer Investments for a prospectus or
summary prospectus containing this information. Read it carefully.

Index Definition
--------------------------------------------------------------------------------
The MSCI U.S. REIT NR 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 10-12.

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.

12 Pioneer Real Estate Shares | Annual Report | 12/31/15


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 1.41%,
     2.24% and 1.02% for Class A, C, and Y shares, respectively, multiplied by
     the average account value over the period, multiplied by 184/365 (to
     reflect the one-half year 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

Notes to Financial Statements | 12/31/15

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 offered three classes of shares designated as Class A, Class C and
Class Y shares. 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 of Trustees 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 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:

A.   Security Valuation

     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.

                        Pioneer Real Estate Shares | Annual Report | 12/31/15 25


     Equity securities that have traded on an exchange are valued by using the
     last sale price on the principal exchange where they are traded. Equity
     securities that have not traded on the date of valuation, or securities for
     which sale prices are not available, generally are valued using the mean
     between the last bid and asked prices or, if both last bid and asked prices
     are not available, at the last quoted bid price. Last sale and bid and
     asked prices are provided by independent third party pricing services. In
     the case of equity securities not traded on an exchange, prices are
     typically determined by independent third party pricing services using a
     variety of techniques and methods.

     Foreign securities are valued in U.S. dollars based on foreign currency
     exchange rate quotations supplied by a third party pricing service. Trading
     in non-U.S. equity 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. The fund may use a fair value model developed by an
     independent pricing service to value non-U.S. equity securities.

     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, 2015, 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).

26 Pioneer Real Estate Shares | Annual Report | 12/31/15


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, 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.

     Security transactions are recorded as of trade date. 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 net 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, 2015, 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.

     A portion of the dividend income recorded by the Fund is from distributions
     by publicly traded REITs, and such distributions for tax purposes may also
     consist of capital gains and return of capital. The actual return of
     capital and capital gains portions of such distributions will be determined
     by formal notifications from the REITs subsequent to the calendar year-end.
     Distributions received from the REITs that are determined to be a return of
     capital are recorded by the Fund as a reduction of the cost basis of the
     securities held and those determined to be capital gain are reflected as
     such on the Statement of Operations.

     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.

          Total                                                  $67,538,668
     =======================================================================


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

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 $15,870 in underwriting commissions on the sale of
     Class A shares during the year ended December 31, 2015.

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 and Class C shares of the Fund (see Note 4). Class
     Y shares do not pay distribution fees. All expenses and fees paid to the
     Fund's transfer agent 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 C and Class Y shares can
     reflect different transfer agent and distribution expense rates.

F.   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.

G.   Repurchase Agreements

     Repurchase agreements are arrangements under which the Fund purchases
     securities from a broker-dealer or a bank, called the counterparty, upon
     the agreement of the counterparty to repurchase the securities from the
     Fund at a later date, and at a specific price, which is typically higher
     than the purchase price paid by the Fund. The securities purchased serve as
     the Fund's collateral for the obligation of the counterparty to repurchase
     the securities. The value of the 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. The Fund's investment adviser, PIM is responsible for determining
     that the value of the collateral remains at least equal to the repurchase
     price. In the event of a default by the counterparty, the Fund is entitled
     to sell the securities, but the Fund may not be able to sell them for the
     price at which they were purchased, thus causing a loss to the Fund.
     Additionally, if the counterparty becomes insolvent, there is some risk
     that the Fund will not have a right to the securities, or the immediate
     right to sell the securities. As of and for the year ended December 31,
     2015, the Fund had no open repurchase agreements.

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, 2015, the effective management fee
(excluding waivers and/or assumption of expenses) was equal to 0.80% of

                        Pioneer Real Estate Shares | Annual Report | 12/31/15 29


the Fund's daily net assets. PIM pays a portion of the management 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
$4,902 in management fees, administrative costs and certain other reimbursements
payable to PIM at December 31, 2015.

3. Transfer Agent

Prior to November 2, 2015, Pioneer Investment Management Shareholder Services,
Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, provided
substantially all transfer agent and shareowner services to the Fund at
negotiated rates.

Effective November 2, 2015, Boston Financial Data Services serves as the
transfer agent to the Fund at negotiated rates.

In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses
incurred by the transfer agent related to shareholder communications activities
such as proxy and statement mailings, outgoing phone calls and omnibus
relationship contracts. For the year ended December 31, 2015, such out-of-pocket
expenses by class of shares were as follows:



-------------------------------------------------------------------------------
 Shareholder Communications:
-------------------------------------------------------------------------------
                                                                    
 Class A                                                               $ 87,120
 Class C                                                                 13,018
 Class Y                                                                 31,142
-------------------------------------------------------------------------------
     Total                                                             $131,280
===============================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $20,340 in transfer agent fees and out-of-pocket reimbursements
payable to the transfer agent at December 31, 2015.

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

30 Pioneer Real Estate Shares | Annual Report | 12/31/15


distribution services with regard to Class C shares. Included in "Due to
affiliates" reflected on the Statement of Assets and Liabilities is $2,088 in
distribution fees payable to PFD at December 31, 2015.

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. 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 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 CDSCs are paid to PFD. For the
year ended December 31, 2015, CDSCs in the amount of $1,885 were paid to PFD.

5. Expense Offset Arrangements

The Fund entered into certain expense offset arrangements with PIMSS. For the
year ended December 31, 2015, 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 until June 9, 2015, was in the amount of $215 million.
As of June 9, 2015, 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 0.85% 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
Eurodollar 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, 2015, the Fund had no borrowings
under the 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, 2015, and the related statement of operations for the year then
ended and the statements of changes in net assets and the financial highlights
for each of the two 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. The financial highlights for the years
ended December 31, 2013, 2012, and 2011 were audited by other auditors. Those
auditors expressed an unqualified opinion on those financial statements and
financial highlights in their report dated February 25, 2014.

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. The Fund
is not required to have, nor were we engaged to perform, an audit of its
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, 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 December 31, 2015, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. 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 as of December 31, 2015, the results of its
operations for the year then ended and the changes in its net assets and the
financial highlights for each of the two years in the period then ended, in
conformity with accounting principles generally accepted in the United States of
America.

Additional Information

PIM, the Fund's investment adviser, is currently an indirect, wholly owned
subsidiary of UniCredit. On November 11, 2015, UniCredit announced that it
signed a binding master agreement with Banco Santander and affiliates of Warburg
Pincus and General Atlantic (the "Private Equity Firms") with respect to Pioneer
Investments ("Pioneer") and Santander Asset Management ("SAM") (the
"Transaction").

The Transaction, as previously announced by UniCredit, will establish a holding
company, with the name Pioneer Investments, to be owned by UniCredit (50%) and
the Private Equity Firms (50% between them). The holding company will control
Pioneer's U.S. operations, including the Adviser. The holding company also will
own 66.7% of Pioneer's and SAM's combined operations outside the U.S., while
Banco Santander will own directly the remaining 33.3% stake. The closing of the
Transaction is expected to happen in 2016, subject to certain regulatory and
other approvals.

Under the Investment Company Act of 1940, completion of the Transaction will
cause the Fund's current investment advisory agreement with PIM to terminate.
Accordingly, the Fund's Board of Trustees will be asked to approve a new
investment advisory agreement. If approved by the Board, the Portfolio's new
investment advisory agreement will be submitted to the shareholders of the Fund
for their approval.

                        Pioneer Real Estate Shares | Annual Report | 12/31/15 33


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. 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 to remain the
investment adviser of the Fund and the sub-adviser to remain the sub-adviser of
the Fund, 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 January 2015 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 2015 and July
2015. Supplemental contract review materials were provided to the Trustees in
September 2015. 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 and sub-advisory agreements.

In March 2015, 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 the sub-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 2015, 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 2015, including the materials provided by the
sub-adviser to the Fund.

At a meeting held on September 15, 2015, 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

34 Pioneer Real Estate Shares | Annual Report | 12/31/15


the sub-advisory agreement for another year. In approving 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. 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 PIM and the sub-adviser to the Fund, taking into account the
investment objective and strategy of the Fund. The Trustees also reviewed the
sub-adviser's investment approach for the Fund and its research process. The
Trustees considered the resources of PIM and the sub-adviser and the personnel
of PIM and the sub-adviser 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 further considered differences in services provided by PIM
and the sub-adviser under the investment advisory agreement and the sub-advisory
agreement, respectively.

The Trustees considered that PIM supervises and monitors the performance of the
Fund's service providers (including the sub-adviser) 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 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

In considering the Fund's performance, the Trustees regularly review and discuss
throughout the year 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
and the sub-adviser on a regular basis. The Trustees' regular reviews and
discussions were factored into the Trustees' deliberations concerning the
renewal of the advisory and sub-advisory agreements.

                        Pioneer Real Estate Shares | Annual Report | 12/31/15 35


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 also considered that PIM, not the Fund, paid the sub-adviser pursuant
to the sub-advisory agreement. The Trustees evaluated both the fee under the
sub-advisory agreement and the portion of the fee under the investment advisory
agreement retained by PIM. In all quintile rankings referred to below, first
quintile is most favorable to the Fund's shareowners.

The Trustees considered that the Fund's management fee for the most recent
fiscal year 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
expense ratio of the Fund's Class A shares for the most recent fiscal year was
in the fourth quintile relative to its Morningstar peer group and in the fourth
quintile relative its Strategic Insight peer group, in each case for the
comparable period. The Trustees noted the Fund's relatively small asset size
compared to most of the other funds in its peer groups, and that the Fund has
not been able to take advantage of the economies of scale afforded by greater
asset size. 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. They Trustees considered
that such non-management fee operating expenses generally are spread over a
smaller asset base than the other funds in the peer group, which results in
these fees being significantly higher as a percentage of assets. 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

36 Pioneer Real Estate Shares | Annual Report | 12/31/15


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 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 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. 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 breakpoint 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

                        Pioneer Real Estate Shares | Annual Report | 12/31/15 37


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 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.
Pioneer is the principal U.S. asset management business of Pioneer Global 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 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.

                 firm, the scope of the Audit
                 Services would likely
                 increase.  The Services are

                 professional standards (AICPA,

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

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.
