PORTFOLIO MANAGEMENT DISCUSSION 6/30/03

High-yield bonds profited from a vibrant rally during the six months ended
June 30, 2003. In the following interview, manager Margaret Patel outlines the
strategy that helped the Portfolio outperform the high-yield market during the
six-month period.

Q:  HOW DID THE PORTFOLIO PERFORM?

A:  During the six months ended June 30, 2003, the Portfolio had a total return
    based on net asset value of 21.23% for the Portfolio's Class I shares. To
    compare, the Merrill Lynch High Yield Master II Index returned 17.88%.

Q:  WHAT WAS THE ENVIRONMENT LIKE FOR THE HIGH-YIELD MARKET DURING THE PAST SIX
    MONTHS?

A:  High-yield bonds enjoyed a strong rally, reflecting a substantial decline in
    the default rate and sustained, albeit sluggish, economic growth. High-yield
    bonds significantly outperformed other segments of the bond market and
    equities as well, rebounding from oversold price levels. Investors became
    attracted to junk bonds against a backdrop of modest economic growth and
    historically low interest rates. Yields offered by Treasuries and other
    higher-quality bond sectors were very low, leading many in the markets to
    look for opportunities among beaten down high-yield bonds.

Q:  WHAT FACTORS HELPED THE PORTFOLIO OUTPERFORM THE MERRILL LYNCH HIGH YIELD
    MASTER II INDEX.

A:  The main factor was the strong performance of a number of the Portfolio's
    investments in convertible securities, which are not part of the Merrill
    Lynch Index. Both the bond and the stock markets heavily influence these
    securities. Many of the Portfolio's convertible positions rose in concert
    with the high-yield bond market, with the rising prices of their underlying
    equities helping to advance their prices as well.

Q:  WHAT WAS YOUR STRATEGY DURING THE PERIOD?

A:  It was unchanged. We continued to focus on companies with business positions
    and liquid resources strong enough to survive in a period of limited
    economic growth. We also looked to invest in companies that were ready to
    benefit from the accelerating economic growth that we expect should occur
    during the second half of 2003. To that end, we added investments in
    economically sensitive sectors such as basic materials, non-ferrous metals,
    chemicals, paper and forest products, and packaging. We also maintained a
    significant allocation to the technology sector, as well as to health care.
    The steady-growth quality of the Portfolio's health care investments - a
    sector that we favor due to its positive demographic trends - worked to
    balance the Portfolio with the economic sensitivity found in other parts.

Q:  DID YOU MAINTAIN A SPECIAL FOCUS ON CONVERTIBLE SECURITIES?

A:  Yes, they are still an important tool for us. Convertible securities are
    bonds that are exchangeable for a set number of shares of common stock at a
    certain price. When we invest in convertible securities, we try to locate
    those that are selling at discounted prices and offering high yields. Our
    aim is to invest in convertible securities issued by companies in industries
    where generic high-yield bonds are not in strong supply, especially smaller
    companies within rapidly growing industries. Discounted convertible
    securities are attractive because their prices can appreciate more than
    regular bonds if the underlying value of the company's stock rises. At the
    same time, holders of convertible bonds can earn the same attractive yields
    as those found in the high-yield market. Technology and health care are two
    sectors where the Portfolio is heavily invested in convertible securities.

Q:  WHICH INVESTMENTS PROVED TO BE SOME OF THE TOP PERFORMERS DURING THE FISCAL
    YEAR? WHICH DISAPPOINTED?

A:  In such a strong period, many of the Portfolio's holdings enjoyed
    particularly healthy gains, and very few lost value. Biotechnology holdings
    such as Imclone and Ligand Pharmaceuticals benefited from a change in
    investor sentiment brought on by well-publicized drug discoveries and an
    expectation that the Food and Drug Administration would speed up its
    approval process. Alpharma and IVAX, two generic pharmaceutical
    manufacturers, posted improved operating results. Technology was very
    strong, with the semiconductor and associated industries showing marked
    improvement, reflecting improving demand. Semiconductor manufacturer
    Conexant Systems was one Portfolio holding that was part of this trend. In
    lodging, Meristar Hospitality - which owns and operates upscale,
    full-service hotels - benefited from an expected turnaround in the travel
    market. Within basic materials, Freeport-MacMoRan rose in response to
    increasing copper prices. On the down side, our very small stake in DDI, a
    specialized computer equipment manufacturer, declined due to reduced demand,
    and we sold the position. PolyOne, a chemical firm, rose but underperformed
    the market as a whole due to pricing pressures.

Q:  WHAT IS YOUR OUTLOOK?

A:  We believe it is likely that the economy will continue to grow, with a
    modest acceleration over the balance of the year and into 2004. With a
    stronger economy and a continued, gradual decline in default rates, we think
    that high-yield bonds should provide attractive yields relative to
    alternatives in more conservative areas of the bond market.

THE PRECEDING INFORMATION IS THE OPINION OF FUND MANAGEMENT. PAST PERFORMANCE IS
NO GUARANTEE OF FUTURE RESULTS, AND THERE IS NO GUARANTEE THAT MARKET FORECASTS
DISCUSSED WILL BE REALIZED.

[SIDENOTE]

The Portfolio invests in high-yield bonds, which may be subject to greater price
fluctuations than investment-grade bonds.

The Portfolio's investment adviser, Pioneer Investment Management, Inc., reduced
its management fee and certain other expenses; otherwise, returns would have
been lower.

PIONEER HIGH YIELD VCT PORTFOLIO

NOTES TO FINANCIAL STATEMENTS 6/30/03 (UNAUDITED)

1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Pioneer Variable Contracts Trust (the Trust) is a Delaware business trust
registered under the Investment Company Act of 1940 as an open-end management
investment company. The Trust consists of sixteen separate portfolios
(collectively, the Portfolios, individually the Portfolio) as follows:

PORTFOLIOS:

    Pioneer Emerging Markets VCT Portfolio (Emerging Markets Portfolio)
    Pioneer Europe VCT Portfolio (Europe Portfolio)
    Pioneer International Value VCT Portfolio (International Value Portfolio)
    Pioneer Small Cap Value VCT Portfolio (Small Cap Value Portfolio)
    Pioneer Small Company VCT Portfolio (Small Company Portfolio
    Pioneer Mid Cap Value VCT Portfolio (Mid-Cap Value Portfolio)
    Pioneer Growth Shares VCT Portfolio (Growth Shares Portfolio)
    Pioneer Real Estate Shares VCT Portfolio (Real Estate Shares Portfolio)
    Pioneer Fund VCT Portfolio (Fund Portfolio)
    Pioneer Equity Income VCT Portfolio (Equity-Income Portfolio)
    Pioneer Balanced VCT Portfolio (Balanced Portfolio)
    Pioneer Value VCT Portfolio (Value Portfolio) (Class II only)
    Pioneer Strategic Income VCT Portfolio (Strategic Income Portfolio)
    Pioneer America Income VCT Portfolio (America Income Portfolio)
    Pioneer Money Market VCT Portfolio (Money Market Portfolio)
    Pioneer High Yield VCT Portfolio (High Yield Portfolio)

Portfolio shares may be purchased by insurance companies for the purpose of
funding variable annuity or variable life insurance contracts, and may also be
purchased by qualified pension and retirement plans.

The investment objective of High Yield Portfolio is to maximize total return
through a combination of income and capital appreciation.

The Trust's financial statements have been prepared in conformity with
accounting principles generally accepted in the United States that require the
management of the Trust 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 revenues and expenses during the reporting years. Actual
results could differ from those estimates. The following is a summary of
significant accounting policies consistently followed by the Trust, which are in
conformity with those generally accepted in the investment company industry:

A.  SECURITY VALUATION

    Security transactions are recorded as of trade date. Net asset values for
    the portfolios are computed once daily, on each day the New York Stock
    Exchange is open, as of the close of regular trading on the Exchange. In
    computing the net asset values, securities 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
    generally reported, are valued at the mean between the last bid and asked
    prices. Trading in foreign equity securities is substantially completed each
    day at various times prior to the close of the New York Stock Exchange. The
    value of such securities used in computing the net asset value of the
    Portfolio's shares, based on the last sale price on the principal exchange
    where they traded, are determined as of such times.

    Fixed income securities are valued at prices supplied by independent pricing
    services, which consider such factors as Treasury spreads, yields,
    maturities and ratings. Valuations may be supplemented by dealers and other
    sources, as required. Securities for which market quotations are not readily
    available are valued at their fair values as determined by, or under the
    direction of, the Board of Trustees.

    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 Portfolio is informed 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, net of
    unrecoverable foreign taxes withheld at the applicable country rates. All
    discounts/premiums are accreted/amortized for financial reporting purposes.

    Gains and losses from sales on investments are calculated on the identified
    cost method for both financial reporting and federal income tax purposes.

    The High Yield Portfolio invests in below investment grade (high yield) debt
    securities and preferred stocks. These high yield securities may be
    convertible into equity securities of the issuer. Debt securities rated
    below investment grade are commonly referred to as "junk bonds" and are
    considered speculative. These securities involve greater risk of loss, are
    subject to greater price volatility, and are less liquid, especially during
    years of economic uncertainty or change, than higher rated debt securities.

                                       13

B.  FOREIGN CURRENCY TRANSLATION

    The books and records of the Portfolio are maintained in U.S. dollars.
    Amounts denominated in foreign currencies are translated into U.S. dollars
    using current exchange rates.

    Net realized gains and losses on foreign currency transactions represent,
    the net realized gains and losses on foreign currency contracts, disposition
    of foreign currencies, and the difference between the amount of income
    accrued and the U.S. dollar actually received. Further, the effects of
    changes in foreign currency exchange rates on investments are not segregated
    in the statement of operations from the effects of changes in market price
    of those securities but are included with the net realized and unrealized
    gain or loss on investments.

C.  FORWARD FOREIGN CURRENCY CONTRACTS

    The Portfolio enters into forward foreign currency contracts (contracts) for
    the purchase or sale of a specific foreign currency at a fixed price on a
    future date as a hedge or cross-hedge against either specific investment
    transactions (settlement hedges) or portfolio positions (portfolio hedges).
    All contracts are marked to market daily at the applicable exchange rates,
    and any resulting unrealized gains or losses are recorded in the Portfolios'
    financial statements. The Portfolio records realized gains and losses at the
    time a portfolio hedge is offset by entry into a closing transaction or
    extinguished by delivery of the currency. Risks may arise upon entering into
    these contracts from the potential inability of counterparties to meet the
    terms of the contract and from unanticipated movements in the value of
    foreign currencies relative to the U.S. dollar.

D.  TAXES

    It is the Trust'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 federal income tax provision is required.

    In addition to the requirements of the Internal Revenue Code, the Portfolio
    may also be required to pay local taxes on the recognition of capital gains
    and/or the repatriation of foreign currencies in certain countries. During
    the six months ended June 30, 2003, the no such taxes were paid.

    The characterization of distributions to shareowners for financial reporting
    purposes is determined in accordance with income tax rules. Therefore, the
    source of each Portfolio's distributions may be shown in the accompanying
    financial statements as either from or in excess of net investment income or
    net realized gain on investment transactions, or from paid-in capital,
    depending on the type of book/tax differences that may exist.

    Capital loss carryforwards are available to offset future realized capital
    gains. At December 31, 2002, High Yield VCT Portfolio had a capital loss
    carryforward of $631,431, which will expire between 2009 and 2010 if not
    utilized.

    The Portfolio elected to defer $59,748 in capital losses recognized between
    November 1, 2002 and December 31, 2002 to its fiscal year ending December
    31, 2003.

    The following chart shows the components of distributable earnings
    (accumulated losses) as of December 31, 2002 and the distributions paid
    during the year ended December 31, 2002 on a tax basis as of December 31,

    the end of the current fiscal year. These amounts do not include the capital
    loss carryforward detailed above.

</Table>

    The difference between book-basis and tax-basis unrealized appreciation
    (depreciation) is primarily attributable to the tax deferral of losses on
    wash sales, returns of capital on REITs, and the recognition of unrealized
    gains or losses on certain futures contracts.

F.  PORTFOLIO SHARES

    The Portfolio records sales and repurchases of its shares as of trade date.
    Certain insurance companies paid Pioneer Funds Distributor, Inc. (PFD), the
    principal underwriter for the Trust and a wholly owned indirect subsidiary
    of UniCredito Italiano S.p.A. (UniCredito Italiano), $30,371 in commissions
    on the sale of portfolio shares for the six months ended June 30, 2003. All
    Dividends are paid on a monthly basis. Short-term capital gain
    distributions, if any, may be declared with the daily dividends. Dividends
    and distributions to shareowners are recorded on the ex-dividend date.

G.  SECURITIES LENDING

    The Portfolio lends securities in its portfolio to certain broker-dealers or
    other institutional investors, with the Portfolios' custodian acting as the
    lending agent. When entering into a loan, the Portfolio receives collateral
    which is maintained by the custodian and earns income in the form of
    negotiated lenders' fees. The Portfolio also continues to receive interest
    or dividends on the securities loaned, and gain or loss in the fair value of
    the securities loaned that may occur during the term of the loan, will be
    for account of the Portfolio. The loans are secured by collateral of at
    least 102%, at all times, of the fair value of the securities loaned. The
    fair value of the collateral will be adjusted daily to reflect any price
    fluctuation in the value of the loaned securities. The value of loaned
    securities and cash collateral at year end are disclosed on the balance
    sheet. The Trust invests cash collateral in the Securities Lending
    Investment Fund which is managed by Brown Brothers Harriman & Co., the
    Trust's custodian.

H.  REPURCHASE AGREEMENTS

    With respect to repurchase agreements entered into by the Portfolio, the
    value of the underlying securities (collateral), including accrued interest
    received from counterparties, is required to be at least equal to or in
    excess of the value of the repurchase agreement at the time of purchase. The
    collateral for all repurchase agreements is held in safekeeping in the
    customer-only account of the Portfolio's custodian, or subcustodian. The
    Trust's investment adviser, Pioneer Investment Management, Inc. (PIM), is
    responsible for determining that the value of the collateral remains at
    least equal to the repurchase price.

2.  MANAGEMENT AGREEMENT

PIM manages the Portfolio, and is a wholly owned indirect subsidiary of
UniCredito Italiano. Management fees are calculated daily at the following
annual rate of 0.65% of the Portfolios' average daily net assets.

PIM has agreed not to impose all or portion of its management fee and to assume
other operating expenses of the Trust to the extent necessary to limit Class I
expenses to 1.30% of the average daily net assets attributable to Class I
shares; the portion of the Trust-wide expenses attributable to Class II shares
will be reduced only to the extent that such expenses are reduced for Class I
shares.

In addition, under the management and administration agreement, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Portfolio. At June 30, 2003, $35,182 was payable to
PIM related to management fees, administrative fees and certain other services.

3.  TRANSFER AGENT

Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned
indirect subsidiary of UniCredito Italiano provides substantially all transfer
agent and shareowner services to the Trust at negotiated rates. Included in due
to affiliates is $857 in transfer agent fees payable to PIMSS at June 30, 2003.

4.  DISTRIBUTION PLANS

The Portfolio has adopted a plan of distribution for Class II shares in
accordance with Rule 12b-1 under the Investment Company Act of 1940. Under the
plan, the Portfolio pays PFD a distribution fee of 0.25% of the average daily
net assets attributable to Class II shares. Included in due to affiliates is
$166 payable to PFD at June 30, 2003.

with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
