PORTFOLIO MANAGER'S COMMENTARY                  JOHN B. JARES & TINO R. SELLITTO

PERFORMANCE

    The Berger IPT-100 Fund's (the "Fund") six-month return for the period ended
June 30, 1999, was 10.16%,(1) which bettered the 6.87% return for the S&P MidCap
400(2) index and lagged the 12.38% return for the Standard & Poor's (S&P) 500(3)
index.

    The stock market was mixed over this six-month period. After favoring large
cap stocks early in the year, the market began to broaden in April as investors
ventured beyond large caps. Mid cap stocks, among others, became more
attractive.

    The fact that our Fund outperformed the mid cap index but trailed the large
cap index reflects our balance between mid cap and large cap holdings in our
portfolio based on market opportunities. Portfolio moves made during this
reporting period attempted to take advantage of the second quarter market
broadening and enabled us to beat the mid cap index.

    Our performance during this period was significantly dampened by two of our
larger holdings--Cadence Design Systems and McKesson HBOC. Cadence Design
Systems, a maker of chip design software, was our single largest stock holding
at the beginning of the year. The stock lost more than half its value on the
announcement that the company could not meet demand and that there was a
shake-up in key management. McKesson HBOC's stock value plummeted upon news of
significant accounting problems following an announced merger. We no longer have
positions in either of these companies in our portfolio.

PERIOD IN REVIEW

    The energy sector continued to perform well as oil prices surged past $19 a
barrel, up from a low of $11. We increased our weighting in energy from 1.2% to
nearly 7% of Fund assets between December 31, 1998, and June 30, 1999. Our Fund
benefited from good performances from energy holdings Halliburton and Royal
Dutch Petroleum Company. We feel positive about future prospects for the energy
sector.

    Our largest sector continues to be technology, which we slightly increased
this reporting period from 24% to 28% of Fund assets. We believe in this sector
for the long term because of the critical role it plays, and will continue to
play, in the operations of businesses around the world. We had particularly
strong performances from Motorola, Xilinx, and Texas Instruments in the second
quarter.

    Among our consumer holdings, Best Buy turned in a strong performance in the
quarter ended June 30.

    Our overweighting in financial stocks early in the year served as a drag on
Fund performance. Particularly in the second quarter, concerns about rising
interest rates and hints of potential inflation worried investors. Financial
stocks were negatively impacted by this move up in interest rates.

LOOKING AHEAD

    Domestic economic growth is robust, and international economies are
recovering from the financial crisis that began nearly two years ago. These
factors should bode well for corporate earnings in the months ahead, although,
as expected, the Federal Reserve Board raised rates by one-quarter percent on
the last day of June. We are concerned about the likelihood of rising interest
rates here at home. This could put pressure on price/earnings multiples and
eventually slow the U.S. economy. We believe that there will be rotation in the
market over the last six months of the year, with periods of outperformance by
growth stocks followed by slower periods.

    Effective May 10, 1999, John Jares and Tino Sellitto became the co-managers
of the Fund replacing Patrick Adams. John has been a portfolio manager for the
Berger Balanced Fund since its inception in 1997. Tino has been the portfolio
manager of the Berger Growth & Income Fund since November 1998. Additionally,
John and Tino have been co-portfolio managers of the Berger 100 Fund since May
10, 1999.

BERGER IPT-GROWTH AND INCOME FUND SEMI-ANNUAL

PORTFOLIO MANAGER'S COMMENTARY                                  TINO R. SELLITTO

PERFORMANCE

    The Berger IPT-Growth and Income Fund (the "Fund") gained 18.34%(1) for the
six-month period ended June 30, 1999, and significantly outperformed the
Standard & Poor's (S&P) 500(2) index, which gained 12.38% over the same period.

    It was a very mixed market in the first half of 1999. During the first
quarter, the market continued to favor the large, high-quality growth companies
that dominate our portfolio. As a result, Fund performance benefited from
holdings in such large cap companies as America Online, At Home and Amgen.

    The market broadened considerably and moved away from these companies during
the second quarter. As a result, Fund performance was dragged down by some of
the same stocks that had buoyed it the previous quarter. However, because of our
emphasis in the technology, energy and consumer sectors, our Fund's six-month
performance was still able to better that of the index.

PERIOD IN REVIEW

    Our sector weighting in technology was virtually unchanged during this
reporting period. We continue to believe in technology's long-term prospects
because of the vital role that it plays in the operations of businesses around
the world. Texas Instruments had a particularly strong first half of the year,
selling its money-losing memory business and increasing its presence in wireless
with digital signal processors.

    The energy sector continued to perform well as oil prices surged past $19 a
barrel, up from a low of $11. We increased our weighting in energy from nearly
6% to 9% of Fund assets between December 31, 1998, and June 30, 1999. Our Fund
benefited from good performances from energy holdings Baker Hughes and
Burlington Resources. We feel positive about future prospects for the energy
sector.

    We also significantly added to our holdings in consumer cyclicals,
increasing investment in that sector from 6% of Fund assets to more than 10%.
Several stocks in this sector, including Dayton-Hudson and Intimate Brands
reported good gains.

    Some of our holdings in the financial sector were volatile this year because
of increasing investor concerns about rising interest rates. This was not the
case, however, for industry leader Charles Schwab. Schwab continued to gain an
impressive share of the market and is now the third-largest financial
institution in terms of U.S. household financial assets. Schwab is also a leader
in online trading and continues to have a low-cost operating structure compared
with full-service brokerage competitors. We believe Charles Schwab is one of the
premier growth companies in the U.S. and look for the company to continue to
expand market share and increase assets in the next few years.

LOOKING AHEAD

    In the second half of the year, we expect the market to be focused on the
direction of interest rates. If inflation continues higher, the Federal Reserve
Board will have to raise rates again, which could hurt the market as a whole.
Given the Fed's announced "neutral" stance on interest rates going forward and
our market analysis, we don't foresee that happening. We do, however, believe
that there will be rotation in the market over the last six months of the year,
with periods of outperformance by growth stocks followed by slower periods.

    be indicative of future performance. The investment return and principal
    value of an investment will fluctuate so that an investor's shares, when
    redeemed, may be worth more or less than their original cost.

(2) The S&P 500 is an unmanaged index, with dividends reinvested, which consists
    of the common stocks of 500 publicly traded U.S. companies. It is a
    generally recognized indicator used to measure overall performance of the

BERGER IPT-SMALL COMPANY GROWTH FUND SEMI-ANNUAL

PORTFOLIO MANAGER'S COMMENTARY                                     AMY K. SELNER

PERFORMANCE

    For the six-month period ended June 30, 1999, the Berger IPT-Small Company
Growth Fund gained 15.72%(1) compared with 9.28% for the Russell 2000 index.(2)

    In the first quarter of 1999, small cap performance, as measured by the
Russell 2000, lagged that of large caps, as measured by the Standard & Poor's
(S&P) 500,(3) by 10.4%. Tables were turned in the second quarter, however, as
small caps outperformed by 8.5%. This was the best quarterly outperformance for
small caps since the fourth quarter 1992 when the spread was 9.4%. Also, second
quarter was the first consecutive three-month period of outperformance by small
cap stocks since the spring of 1996.

    Strength in the Russell 2000 occurred despite general weakness in Internet
stocks, which accounted for 10% of the index. Within the small cap group, growth
stocks outperformed value stocks in the first quarter, and value stocks had a
very strong second quarter. Small cap value stocks had been pummeled in the
first quarter and were due for a short-term bounce.

    In June, small cap funds had positive inflows reversing five months of large
cash outflows in 1999. This is a trend we would like to see continue, along with
a broadening of the market. Rising interest rates in the short term may have
increased the attention given to small caps, which are much cheaper than large
caps on a relative valuation basis.

PERIOD IN REVIEW

    After taking a breather in April and May, technology stocks roared back in
June. Growth prospects remained explosive for the Internet infrastructure and
telecommunication and broadband companies. These are companies that provide the
"plumbing" that enables broad acceptance for Internet applications and services.
Within the semiconductor capital equipment stocks, we prefer the photomask,
Dupont Photomasks, and automation, PRI Automation, verticals. These companies
make the equipment to build semiconductors. Their customers are moving to
next-generation technologies, which bodes well for spending on equipment.

    Although small cap health care stocks lagged the index in performance, our
holdings turned in respectable performances. As uncertainty surrounding
prescription drug benefits and the government's impact on pricing within the
drug industry lifts, we expect performance to be even stronger. We continued to
emphasize growth companies in the bio-tech area such as Cephalon, which focuses
on treatment of neurological disorders and cancer, and on companies with strong
pipelines, consistent earnings growth and strong management.

    We also continued our heavy weighting in energy, which began mid first
quarter 1999. This has proved advantageous. Supply/demand dynamics within the
sector have improved, energy prices have risen, and energy stocks have been
strong. Since the first of the year, crude oil prices are up close to 60%,
driven largely by high levels of OPEC compliance and an improving outlook for
demand in 2000/2001. Natural gas prices also remain strong. Both Veritas DGC and
Basin Exploration have been strong performers for our Fund.

LOOKING AHEAD

    The market has quickly discounted the Federal Reserve Board's one-quarter
percent increase in interest rates and is assuming the Fed will remain neutral
during the second half of the year. We expect consumption growth will moderate
to more sustainable levels and housing growth to slow. Even with this
moderation, there is a risk the Fed may raise rates again to squelch any
inflation fears, which today are nonexistent. We believe market leadership will
continue to rotate from sector to sector, and we look for growth stocks to
continue to outperform.

    While relative valuation currently favors small caps, the operating profit
growth of small caps must improve relative to large caps in order for this
outperformance to be sustained. This may be difficult when GDP growth
internationally may be accelerating relative to domestic growth in 2000. Larger
cap stocks would generally have better profit prospects under that scenario. We
continue to focus on exceptional stock selection to distinguish the relative
performance of our Fund.

BERGER/BIAM IPT-INTERNATIONAL FUND SEMI-ANNUAL

PORTFOLIO MANAGER'S COMMENTARY      BANK OF IRELAND ASSET MANAGEMENT (U.S.) LTD.

PERFORMANCE

    The Berger/BIAM IPT-International Fund (the "Fund") gained 6.24%(1) over the
six-month period ended June 30, 1999, which bettered the 4.11% gain for the MSCI
EAFE Index.(2) Several stocks in the Growth in Telecommunications theme were
among the most significant contributors to this solid performance, particularly
Vodafone in the first quarter and NTT DoCoMo in the second quarter. Mannesmann
delivered strong returns in both quarters.

    Telecom stocks were driven higher primarily by explosive growth in worldwide
mobile phone usage. Analysts have consistently underestimated the rate of this
growth, and there is little reason to believe the rate will slow in the near
future. The industry also benefited from rising fixed-line call volume, boosted
by Internet traffic, and increasing merger and acquisition activity.

    Japanese companies in the Technological Innovation theme aided Fund
performance this reporting period. Canon unveiled positive earnings news and
announced an alliance with Toshiba to develop flat panel TV screens. Murata
Manufacturing, despite a decline in profits, had a stronger than anticipated
order book and forecast a profit increase over the next 12 months. Sony's stock
received a boost following the company's announcement that it would refocus on
its traditional electronics businesses.

    Other Japanese companies in a variety of themes also made positive
contributions to Fund performance. This is not surprising given that Japan has
been the best performer among the world's major equity markets since January 1,
1999.

    On the negative side, a number of stocks in the Healthcare Needs theme did
not fare well, as many investors decided cyclical companies offered better value
than traditional growth companies such as pharmaceuticals. Glaxo Wellcome
suffered after reporting increased competition for some of its key drugs.
Insurance companies also generally underperformed because of concerns about the
impact of rising U.S. interest rates. Swiss Re, the world's second-largest
reinsurer declined on belief that non-life reinsurance will suffer as the number
of natural catastrophes increases.

PERIOD IN REVIEW

    European stock markets have been on a six-month roller-coaster ride. They
got off to a flying start in January as investors came back into the market
following the introduction of the new euro currency. But signs of deteriorating
market conditions led the markets down in February. After a stronger March, the
European Central Bank cut interest rates by one-half percent in April--twice the
level expected. The markets performed well that month but were weaker in May.
The unexpected neutral interest rate bias announced by the U.S. Federal Reserve
Board sparked a June rally.

    Positive sentiment toward the Japanese market was revived in January as
investors were encouraged by merger rumors in the banking sector and indications
of plans to apply for additional public funding by a number of banks. After
moving sideways in February, the market rose sharply in March, driven primarily
by overseas buying. The rally continued in April but stalled in May following
some trade friction with the U.S. and a drop in industrial production. After the
announcement of first-quarter GDP growth of 1.9%, the Japanese market took off
again. International investors, particularly Americans, continued to build their
weightings in Japanese companies, fueling the positive sentiment.

    Other Asian markets began to show signs of recovery in March and enjoyed an
explosive rally in April. Throughout the region, a pickup in industrial
production and imports was hailed as a signal of the end of economic crisis.
Asian markets continued strong in June, aided by falling interest rates and
positive investor sentiment. Economies across Asia are looking better, and
recovery from the bottom is definitely evident.

LOOKING AHEAD

    Much investor focus has been on whether the cyclical stock rally is
long-term or temporary. We continue to look for companies capable of
above-average earnings growth on a company-by-company basis rather than
across-the-board sector allocations. We remain extremely cautious about
investing in Southeast Asia, even though the acute crisis appears to be over.
Although Japanese figures have been strong, we believe Japan is a stock-picker's
market because not all companies will deliver on the promises they are making to
investors. In Europe, the new euro currency received negative press following
its steady decline against the U.S. dollar and other major currencies. The euro
is acting as a catalyst for change, however, and is increasing competition
across Europe. We will continue to seek companies at the forefront of this
change that can significantly grow their earnings in the single-currency
environment. We believe telecommunications, pharmaceutical and financial service
companies are most likely to benefit from the single currency and have
positioned the portfolio accordingly.

                         NOTES TO FINANCIAL STATEMENTS

                           JUNE 30, 1999 (UNAUDITED)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

    Berger Institutional Products Trust (the "Trust"), a Delaware business
trust, was established on October 17, 1995 as a diversified open-end management
investment company. The Trust is authorized to issue an unlimited number of
shares of beneficial interest in series or portfolios. Currently, the series
comprising Berger IPT-100 Fund ("IPT-100"), Berger IPT-Growth and Income Fund
("IPT-G&I"), Berger IPT-Small Company Growth Fund ("IPT-SCG") and Berger/BIAM
IPT-International Fund ("IPT-International"), (individually the "Fund" and
collectively the "Funds") are the only portfolios established under the Trust,
although others may be added in the future. The Funds commenced investment
operations on May 1, 1996, except for IPT-International which commenced
investment operations on May 1, 1997.

    The Trust is registered under the Investment Company Act of 1940 and its
shares are registered under the Securities Act of 1933 (the "Acts"). Shares of
each Fund are fully paid and non-assessable when issued. All shares issued by a
particular Fund participate equally in dividends and other distributions by that
Fund. The Trust's shares are not offered directly to the public, but are sold
exclusively to insurance companies ("Participating Insurance Companies") as a
pooled funding vehicle for variable annuity and variable life insurance
contracts issued by separate accounts of Participating Insurance Companies and
to qualified plans. All costs incurred in organizing the Trust were paid by
Berger Associates, Inc. ("Berger"), the investment advisor to IPT-100, IPT-G&I
and IPT-SCG and by BBOI Worldwide LLC ("BBOI"), the investment advisor to
IPT-International.

    At June 30, 1999, Berger, directly or indirectly, owned 6% and 45% of the
outstanding shares of IPT-100 and IPT-International, respectively.

SIGNIFICANT ACCOUNTING POLICIES

    The following is a summary of significant accounting policies consistently
followed by the Funds in the preparation of their financial statements. The
policies are in conformity with generally accepted accounting principles.

INVESTMENT VALUATION

    Securities are valued at the close of the regular trading session of the New
York Stock Exchange (the "Exchange") on each day that the Exchange is open.
Securities listed on national exchanges, the NASDAQ Stock Market and foreign
exchanges are valued at the last sale price on such markets, or, if no last sale
price is available, they are valued using the mean between their current bid and
asked prices. Securities traded in the over-the-counter market are valued at the
mean between their current bid and asked prices. Short-term obligations maturing
within sixty days are valued at amortized cost, which approximates market value.
Securities for which quotations are not readily available are valued at fair
values determined in good faith pursuant to consistently applied procedures
established by the trustees of the Funds.

    Generally, trading in foreign securities markets is substantially completed
each day at various times prior to the close of the Exchange. The values of
foreign securities used in computing the net asset value of the shares in the
Funds are determined as of the earlier of such market close or the closing time
of the Exchange. Occasionally, events affecting the value of such securities may
occur between the times at which they are determined and the close of the
Exchange, or when the foreign market on which such securities trade is closed
but the Exchange is open, which will not be reflected in the computation of net
asset value. If during such periods, events occur which materially affect the
value of such securities, the securities will be valued at their fair market
value as determined in good faith pursuant to consistently applied procedures
established by the trustees.

FORWARD CONTRACTS AND OPTIONS

    Each Fund may hold certain types of forward foreign currency contracts
and/or options (except for IPT-International, which may only hold forward
foreign currency exchange contracts) for the purpose of hedging each portfolio
against exposure to market fluctuations. The use of such instruments may involve
certain risks as a result of unanticipated movements in the market. A lack of
correlation between the value of such instruments and the assets being hedged,
or unexpected adverse price movements, could render a Fund's hedging strategy
unsuccessful. In addition, there can be no

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                           JUNE 30, 1999 (UNAUDITED)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
assurance that a liquid secondary market will exist for the instrument. Realized
gains or losses on these securities are included in Net Realized Gain (Loss) on
Investments and Foreign Currency Transactions in the Statement of Operations.

CONCENTRATION OF RISK

    The Fund may have elements of risk due to concentrated investments in
specific industries or foreign issuers located in a specific country. Such
concentrations may subject the Fund to additional risks resulting from future
political or economic conditions and/or possible impositions of adverse foreign
governmental laws or currency exchange restrictions. Net realized and unrealized
gain or loss from investment securities includes fluctuations from currency
exchange rates and fluctuations in market value.

CALCULATION OF NET ASSET VALUE

    Each Fund's per share calculation of net asset value is determined by
dividing the total value of its assets, less liabilities, by the total number of
shares outstanding.

FEDERAL INCOME TAX STATUS

    It is the Funds' policy to comply with the requirements of the Internal
Revenue Code ("Code") applicable to regulated investment companies and to
distribute all of their taxable income to shareholders. Therefore, no income tax
provision is required.

FOREIGN CURRENCY TRANSLATION

    Assets and liabilities initially expressed in terms of foreign currencies
are translated into U.S. dollars at the prevailing market rates as quoted by one
or more banks or dealers on the date of valuation. The cost of securities is
translated into U.S. dollars at the rates of exchange prevailing when such
securities were acquired. Income and expenses are translated into U.S. dollars
at rates of exchange prevailing when accrued.

INVESTMENT TRANSACTIONS AND INVESTMENT INCOME

    Investment transactions are accounted for on the date investments are
purchased or sold. Dividend income is recorded on the ex-dividend date. Certain
dividends from foreign securities will be recorded as soon as the Fund is
informed of the dividend if such information is obtained subsequent to the
ex-dividend date. Interest income is recorded on the accrual basis and includes
amortization of discounts and premiums. Gains and losses are computed on the
identified cost basis for both financial statement and federal income tax
purposes for all securities.

COMMON EXPENSES

    Certain expenses, which are not directly allocable to a specific fund of the
Trust, are allocated to the Funds on the basis of relative net assets.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of increases and decreases in net assets
from operations during the reporting period. Actual results could differ from
those estimates.

2. AGREEMENTS

    Berger serves as the investment advisor to IPT-100, IPT-G&I and IPT-SCG and
BBOI serves as the investment advisor to IPT-International. Berger and Bank of
Ireland Asset Management (U.S.) Limited ("BIAM") each own 50% of BBOI. BBOI has
delegated the day-to-day portfolio management of IPT-International to BIAM. As
compensation for their

2. AGREEMENTS (CONTINUED)
services to the Funds, Berger and BBOI receive an investment advisory fee, which
is accrued daily at the applicable rate and paid monthly. The fees are based on
an annual rate of each Fund's average daily net assets as follows: IPT-100 and
IPT-G&I at .75%; IPT-SCG and IPT-International at .90%. As sub-advisor to
IPT-International, BIAM receives a sub-advisory fee from BBOI at an annual rate
of .40% of the average daily net assets of the Fund. Such sub-advisory fees have
been voluntarily waived by BIAM for the period from May 1, 1997 to October 15,
2000. Additionally, Berger and BBOI have agreed to waive their advisory fees and
reimburse expenses to the Funds to the extent that normal operating expenses in
any fiscal year (including the advisory fee but excluding brokerage commissions,
interest, taxes and extraordinary expenses) exceed 1.00% of the average daily
net assets of both IPT-100 and IPT-G&I, 1.15% of the average daily net assets of
IPT-SCG and 1.20% of the average daily net assets of IPT-International.

    IPT-100, IPT-G&I and IPT-SCG have entered into administrative services
agreements with Berger. The administrative services agreements provide for a fee
at the annual rate of .01% of the average daily net assets of each Fund. Such
fee is accrued daily and paid monthly. IPT-International has entered into an
administrative services agreement with BBOI. The administrative services
agreement provides for a fee at an annual rate of .01% of the average daily net
assets of the Fund accrued daily and paid monthly. BBOI has delegated the
day-to-day administrative duties to Berger. Berger receives a sub-administration
fee from BBOI at an annual rate of .20% of the average daily net assets of
IPT-International. Berger has voluntarily waived such sub-administration fee for
the period from May 1, 1997 to June 30, 1999.

    The Trust has entered into a recordkeeping and pricing agreement with
Investors Fiduciary Trust Company ("IFTC"), who also serves as each Fund's
custodian and transfer agent. The recordkeeping and pricing agreement provides
for the monthly payment of a base fee per Fund plus a fee computed as a
percentage of average daily net assets on a total relationship basis. IFTC's
fees for custody, recordkeeping, pricing, and transfer agency services are
subject to reduction by credits earned by each Fund, based on the cash balances
of the Fund held by IFTC as custodian or by credits received from directed
brokerage transactions.

    DST Systems, Inc. ("DST"), an affiliate of Berger through a degree of common
ownership, provides shareholder accounting services to the Funds. DST
Securities, Inc., a wholly owned subsidiary of DST, is designated as an
introductory broker on certain portfolio transactions. The Funds receive an
amount equal to the brokerage commissions paid to DST Securities, Inc. as
credits against transfer agent fees and expenses. For the six months ended June
30, 1999, the IPT-100 and IPT-G&I, received brokerage credits totaling $385 and
$266 respectively.

    Certain officers and/or directors of Berger and BBOI are also officers
and/or trustees of the Trust. Trustees who are not affiliated with Berger or
BBOI received trustees' fees totaling $224, $598, $529 and $288 from IPT-100,
IPT-G&I, IPT-SCG, and IPT-International Fund, respectively, for the six months
ended June 30, 1999.

    The Trust adopted a trustee fee deferral plan (the "Plan") which allows the
trustees to defer the receipt of all or a portion of the fees payable. The
deferred fees are invested in various Berger Funds until distribution in
accordance with the Plan.

FEDERAL INCOME TAXES

    Dividends received by shareholders of the Funds which are derived from
foreign source income and foreign taxes paid by the Funds are to be treated, to
the extent allowable under the Code, as if received and paid by the shareholders
of the fund.

    At December 31, 1998, the IPT-100, IPT-G&I and IPT-International had
$156,868, $418,961 and $172,062, respectively, in net capital loss carryovers
which expire in the year 2006. Additionally, IPT-SCG had $16,903, $39,451 and
$931,350 in capital loss carryovers which expire in the years 2004, 2005, and
2006, respectively. The capital loss carryovers may be used to offset future
realized capital gains for federal income tax purposes.

    Additionally, IPT-100, IPT-SCG and IPT-International incurred and elected to
defer post-October 31 net capital and/or currency losses of $6,312, $34,842, and
$45,992, respectively, to the year ended December 31, 1999.

    The Funds distribute net realized capital gains, if any, to their
shareholders at least annually, if not offset by capital loss carryovers. Income
distributions and capital gain distributions are determined in accordance with
income tax regulations which may differ from generally accepted accounting
principles.

    The differences are primarily due to the differing treatment of net
operating losses, wash sale deferrals, capital loss carryforwards and foreign
currency transactions. Accordingly, these differences in the character of income
and distributions between financial statements and tax basis have been
reclassified to paid-in-capital.
