CREDIT SUISSE TRUST - GLOBAL SMALL CAP PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

                                                                January 19, 2006
Dear Shareholder:

      For the 12 months ended December 31, 2005, Credit Suisse Trust--Global
Small Cap Portfolio *,1 (the "Portfolio") had a gain of 16.14%, vs. an increase
of 12.10% for the Russell MidCap (R) Growth Index 2, an increase of 14.25% for
the Morgan Stanley Capital International World Small Cap Index (Price Only) 2,
and an increase of 10.02% for the Morgan Stanley World Index. 2

THE MARKET: FOREIGN STOCKS OUTPERFORM US EQUITIES

      The year was a broadly positive one for equities globally, and most
foreign markets handily outpaced US stocks, at least in local currency terms.
European markets generally posted double-digit gains in euro terms, aided in
part by a relatively benign interest-rate backdrop. Japan was a notable
standout, up about 40% locally, amid signs that the world's second largest
economy may be poised for a sustainable recovery at long last. For dollar-based
investors, a decline in major currencies vs. the dollar reduced returns, though
most foreign markets still outperformed the US on that basis. Emerging markets
generally had the best dollar-based results in 2005.

      From a sector standpoint, energy was the best performing area of the US
stock market. Energy stocks also outperformed abroad, though materials and
industrials stocks had even better returns overseas for the period. Consumer
stocks generally underperformed globally.

STRATEGIC REVIEW: AIDED BY STOCK SELECTION

      The Portfolio was supported by the favorable environment for small caps
globally, and its outperformance reflected good stock selection in a variety of
sectors. Stocks that contributed positively to the Portfolio's absolute and
relative performance included its materials, industrials, health care and
consumer-related holdings. The Portfolio's technology and utilities holdings
modestly underperformed in the period.

      With respect to noteworthy recent portfolio activity, our purchases
included Salesforce.com (1.4% of the Portfolio's net assets as of December 31,
2005), a software company that licenses its enterprise resource planning
applications to a number of large companies. Our late-period sales included Colt
Telecom, a UK based provider of business telecommunications services across
Europe. The stock had rallied to reach our sell target. We also exited our
position in Mega

Bloks, a Canadian toy company, based on valuation along with our concerns
regarding an acquisition the company made recently.

      Going forward, we will continue to employ a bottom-up investment approach,
seeking to identify companies trading at a discount to their projected growth
rates or intrinsic asset values. Factors we incorporate include price/earnings
growth, book value, strong returns on capital and reliability and effectiveness
of management.

      The Portfolio ordinarily holds equity securities of small companies from
at least three countries, including the US, and we seek to take advantage of
both growth and value opportunities. The Portfolio's investable universe is
hence broad and large, and our focus remains on attempting to find innovative
companies with unrecognized potential.

2     The Russell MidCap(R) Growth Index and the Morgan Stanley Capital
      International World Index were benchmarks for the Global Small Cap
      Portfolio. The Russell MidCap(R) Growth Index measures the performance of
      those companies in the Russell MidCap(R) Index with higher price-to-book
      ratios and higher forecasted growth values. The stocks are also members of
      the Russell 1000(R) Growth Index. It is an unmanaged index of common
      stocks that includes reinvestment of dividends and is compiled by Frank
      Russell Company. The Morgan Stanley Capital International World Index is a
      free float-adjusted market-capitalization index that is designed to
      measure global developed-market equity performance. It is the exclusive
      property of Morgan Stanley Capital International Inc. The Morgan Stanley
      Capital International World Small Cap Index is an unmanaged broadbased
      index comprised of small cap companies from 23 developed markets. The
      index returns shown above are price only and do not reflect the
      reinvestment of dividends. It is the exclusive property of Morgan Stanley
      Capital International Inc. In order to reflect changes to the Portfolio's
      investment policy and name, the Morgan Stanley Capital International World
      Small Cap Index replaced the Morgan Stanley Capital International World
      Index and the Russell MidCap(R) Growth Index as the Portfolio's benchmark
      effective February 21, 2005. Investor cannot invest directly in an index.

ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

INFORMATION ABOUT YOUR PORTFOLIO'S EXPENSES

      As an investor of the Portfolio, you incur two types of costs: ongoing
expenses and transaction costs. Ongoing expenses include management fees,
distribution and service (12b-1) fees and other Portfolio expenses. Examples of
transaction costs include sales charges (loads), redemption fees and account
maintenance fees, which are not shown in this section and which would result in
higher total expenses. The following table is intended to help you understand
your ongoing expenses of investing in the Portfolio and to help you compare
these expenses with the ongoing expenses of investing in other mutual funds. The
table is based on an investment of $1,000 made at the beginning of the six month
period ended December 31, 2005.

      The table illustrates your Portfolio's expenses in two ways:

      o     ACTUAL PORTFOLIO RETURN. This helps you estimate the actual dollar
            amount of ongoing expenses paid on a $1,000 investment in the
            Portfolio using the Portfolio's actual return during the period. To
            estimate the expenses you paid over the period, simply divide your
            account value by $1,000 (for example, an $8,600 account value
            divided by $1,000 = 8.6), then multiply the result by the number in
            the "Expenses Paid per $1,000" line under the share class you hold.

      o     HYPOTHETICAL 5% PORTFOLIO RETURN. This helps you to compare your
            Portfolio's ongoing expenses with those of other mutual funds using
            the Portfolio's actual expense ratio and a hypothetical rate of
            return of 5% per year before expenses. Examples using a 5%
            hypothetical fund return may be found in the shareholder reports of
            other mutual funds. The hypothetical account values and expenses may
            not be used to estimate the actual ending account balance or
            expenses you paid for the period.

      Please note that the expenses shown in these tables are meant to highlight
your ongoing expenses only and do not reflect any transaction costs, such as
sales charges (loads) or redemption fees. If these transaction costs had been
included, your costs would have been higher. The "Expenses Paid per $1,000" line
of the tables is useful in comparing ongoing expenses only and will not help you
determine the relative total expenses of owning different funds.

ANNUALIZED EXPENSE RATIOS*                                                1.40%

______________

*     EXPENSES ARE EQUAL TO THE PORTFOLIO'S ANNUALIZED EXPENSE RATIO MULTIPLIED
      BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY THE NUMBER OF
      DAYS IN THE MOST RECENT FISCAL HALF YEAR PERIOD, THEN DIVIDED BY 365.

      THE "EXPENSES PAID PER $1,000" AND THE "ANNUALIZED EXPENSE RATIOS" IN THE
      TABLES ARE BASED ON ACTUAL EXPENSES PAID BY THE PORTFOLIO DURING THE
      PERIOD, NET OF FEE WAIVERS AND/OR EXPENSE REIMBURSEMENTS. IF THOSE FEE
      WAIVERS AND/OR EXPENSE REIMBURSEMENTS HAD NOT BEEN IN EFFECT, THE
      PORTFOLIO'S ACTUAL EXPENSES WOULD HAVE BEEN HIGHER. EXPENSES DO NOT
      REFLECT ADDITIONAL CHARGES AND EXPENSES THAT ARE, OR MAY BE, IMPOSED UNDER
      THE VARIABLE CONTRACTS OR PLANS. SUCH CHARGES AND EXPENSES ARE DESCRIBED
      IN THE PROPECTUS OF THE INSURANCE COMPANY SEPERATE ACCOUNT OR IN THE PLAN
      DOCUMENTS OR OTHER INFOMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS. THE
      PORTFOLIO'S EXPENSES SHOULD BE CONSIDERED WITH THESE CHARGES AND EXPENSES
      IN EVALUATING THE OVERALL COST OF INVESTING IN THE SEPARATE ACCOUNT.

For more information, please refer to the Portfolio's prospectus.

CREDIT SUISSE TRUST - GLOBAL SMALL CAP PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
December 31, 2005
- --------------------------------------------------------------------------------

NOTE 1. ORGANIZATION

      Credit Suisse Trust, (the "Trust") is an open-end management investment
company registered under the Investment Company Act of 1940, as amended, and
currently offers eight managed investment portfolios of which one, the Global
Small Cap Portfolio (the "Portfolio"), is included in this report. The Portfolio
is a diversified investment fund that seeks long-term growth of capital. Shares
of the Portfolio are not available directly to individual investors but may be
offered only through (a) variable annuity contracts and variable life insurance
contracts offered by separate accounts of certain insurance companies and (b)
tax-qualified pension and retirement plans. The Portfolio may not be available
in connection with a particular contract or plan. The Trust was organized under
the laws of The Commonwealth of Massachusetts as a business trust on March 15,
1995. The name of the Portfolio was changed from Credit Suisse Trust - Global
Post-Venture Capital Portfolio effective February 21, 2005.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      A) SECURITY VALUATION - The net asset value of the Portfolio is determined
daily as of the close of regular trading on the New York Stock Exchange, Inc.
(the "Exchange") on each day the Exchange is open for business. The Portfolio's
equity investments are valued at market value, which is generally determined
using the closing price on the exchange or market on which the security is
primarily traded at the time of valuation (the "Valuation Time"). If no sales
are reported, equity investments are generally valued at the most recent bid
quotation as of the Valuation Time or at the lowest asked quotation in the case
of a short sale of securities. Debt securities with a remaining maturity greater
than 60 days are valued in accordance with the price supplied by a pricing
service, which may use a matrix, formula or other objective method that takes
into consideration market indices, yield curves and other specific adjustments.
Debt obligations that will mature in 60 days or less are valued on the basis of
amortized cost, which approximates market value, unless it is determined that
using this method would not represent fair value. Investments in mutual funds
are valued at the mutual fund's closing net asset value per share on the day of
valuation. Securities and other assets for which market quotations are not
readily available, or whose values have been materially affected by events
occurring before the Portfolio's Valuation Time but after the close of the
securities' primary markets, are valued at fair value as determined in good
faith by, or under the direction of, the Board of Trustees

                                       20




CREDIT SUISSE TRUST - GLOBAL SMALL CAP PORTFOLIO
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

- --------------------------------------------------------------------------------

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

under procedures established by the Board of Trustees. The Portfolio may utilize
a service provided by an independent third party which has been approved by the
Board of Trustees to fair value certain securities. When fair-value pricing is
employed, the prices of securities used by a fund to calculate its net asset
value may differ from quoted or published prices for the same securities.

      The Portfolio initially values its investments in private-equity
portfolios ("Private Funds") at the amount invested in the Private Funds, less
related expenses, where identifiable, unless and until Credit Suisse Asset
Management, LLC ("Credit Suisse") determines that such value does not represent
fair value. Thereafter, investments in Private Funds held by the Portfolio are
valued at their "fair values" using procedures approved by the Board of
Trustees. Credit Suisse shall review daily the Portfolio's fair valued
securities.

      B) FOREIGN CURRENCY TRANSACTIONS - The books and records of the Portfolio
are maintained in U.S. dollars. Transactions denominated in foreign currencies
are recorded at the current prevailing exchange rates. All assets and
liabilities denominated in foreign currencies are translated into U.S. dollar
amounts at the current exchange rate at the end of the period. Translation gains
or losses resulting from changes in the exchange rate during the reporting
period and realized gains and losses on the settlement of foreign currency
transactions are reported in the results of operations for the current period.
The Portfolio does not isolate that portion of realized gains and losses on
investments in EQUITY securities which is due to changes in the foreign exchange
rate from that which is due to changes in market prices of equity securities.
The Portfolio isolates that portion of realized gains and losses on investments
in DEBT securities which is due to changes in the foreign exchange rate from
that which is due to changes in market prices of debt securities.

      C) SECURITY TRANSACTIONS AND INVESTMENT INCOME - Security transactions are
accounted for on a trade date basis. Interest income is recorded on the accrual
basis. Dividends are recorded on the ex-dividend date. The cost of investments
sold is determined by use of the specific identification method for both
financial reporting and income tax purposes.

      D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS - Dividends from net
investment income and distributions of net realized capital gains, if any, are
declared and paid at least annually. However, to the extent that a net

                                       21

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

realized capital gain can be reduced by a capital loss carryforward, such gain
will not be distributed. Income and capital gain distributions are determined in
accordance with federal income tax regulations, which may differ from accounting
principles generally accepted in the United States of America ("GAAP").

      E) FEDERAL INCOME TAXES - No provision is made for federal taxes as it is
the Trust's intention to have the Portfolio continue to qualify for and elect
the tax treatment applicable to regulated investment companies under the
Internal Revenue Code of 1986, as amended, and to make the requisite
distributions to its shareholders, which will be sufficient to relieve it from
federal income and excise taxes.

      F) USE OF ESTIMATES - The preparation of financial statements in
conformity with GAAP 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 revenues and expenses during the reporting period.
Actual results could differ from these estimates.

      G) SHORT TERM INVESTMENTS - The Portfolio, together with other funds/
portfolios advised by Credit Suisse, an indirect, wholly-owned subsidiary of
Credit Suisse Group, pools available cash into either a short-term variable rate
time deposit issued by State Street Bank and Trust Company ("SSB"), the
Portfolio's custodian, or a money market fund advised by Credit Suisse. The
short-term time deposit issued by SSB is a variable rate account classified as a
short-term investment.

      H) FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into
forward foreign currency contracts for the purchase or sale of a specific
foreign currency at a fixed price on a future date. Risks may arise upon
entering into these contracts from the potential inability of counterparties to
meet the terms of their contracts and from unanticipated movements in the value
of a foreign currency. The Portfolio will enter into forward foreign currency
contracts primarily for hedging purposes. Forward foreign currency contracts are
adjusted by the daily forward exchange rate of the underlying currency and any
gains or losses are recorded for financial statement purposes as unrealized
until the contract settlement date or an offsetting position is entered into. At
December 31, 2005, the Portfolio had no open forward foreign currency contracts.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      I) SECURITIES LENDING - Loans of securities are required at all times to
be secured by collateral at least equal to 102% of the market value of domestic
securities on loan (including any accrued interest thereon) and 105% of the
market value of foreign securities on loan (including any accrued interest
thereon). Cash collateral received by the Portfolio in connection with
securities lending activity may be pooled together with cash collateral for
other funds/portfolios advised by Credit Suisse and may be invested in a variety
of investments, including certain Credit Suisse-advised funds, funds advised by
SSB, the Portfolio's securities lending agent, or money market instruments.
However, in the event of default or bankruptcy by the other party to the
agreement, realization and/or retention of the collateral may be subject to
legal proceedings.

      SSB has been engaged by the Portfolio to act as the Portfolio's securities
lending agent. The Portfolio's securities lending arrangement provides that the
Portfolio and SSB will share the net income earned from securities lending
activities. During the year ended December 31, 2005, total earnings from the
Portfolio's investment in cash collateral received in connection with securities
lending arrangements was $941,870, of which $722,872 was rebated to borrowers
(brokers). The Portfolio retained $153,845 in income from the cash collateral
investment, and SSB, as lending agent, was paid $65,153. The Portfolio may also
be entitled to certain minimum amounts of income from its securities lending
activities. Securities lending income is accrued as earned.

      J) PARTNERSHIP ACCOUNTING POLICY - The Portfolio records its pro-rata
share of the income/(loss) and capital gains/(losses) allocated from the
underlying partnerships and adjusts the cost of the underlying partnerships
accordingly. These amounts are included in the Portfolio's Statement of
Operations.

      K) OTHER - The Portfolio may invest in securities of foreign countries and
governments which involve certain risks in addition to those inherent in
domestic investments. Such risks generally include, among others, currency risk
(fluctuations in currency exchange rates), information risk (key information may
be inaccurate or unavailable) and political risk (expropriation, nationalization
or the imposition of capital or currency controls or punitive taxes). Other
risks of investing in foreign securities include liquidity and valuation risks.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      The Portfolio may be subject to taxes imposed by countries in which it
invests, with respect to its investments in issuers existing or operating in
such countries. Such taxes are generally based on income earned or repatriated
and capital gains realized on the sale of such investments. The Portfolio
accrues such taxes when the related income is earned or gains are realized.

      The Portfolio may invest up to 15% of its net assets in non-publicly
traded securities. Non-publicly traded securities may be less liquid than
publicly traded securities. Although these securities may be resold in privately
negotiated transactions, the prices realized from such sales could differ from
the price originally paid by the Portfolio or the current carrying values, and
the difference could be material.

NOTE 3. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

      Credit Suisse serves as investment adviser for the Portfolio. For its
investment advisory services, Credit Suisse is entitled to receive a fee from
the Portfolio at an annual rate of 1.25% of the Portfolio's average daily net
assets. For the year ended December 31, 2005, investment advisory fees earned
and voluntarily waived for the Portfolio were $1,445,342 and $217,554,
respectively. Credit Suisse will not recapture from the Portfolio any fees it
waived during the fiscal year ended December 31, 2005. Fee waivers and
reimbursements are voluntary and may be discontinued by Credit Suisse at any
time.

      Credit Suisse Asset Management Limited (U.K.) ("Credit Suisse U.K."), and
Credit Suisse Asset Management Limited (Australia) ("Credit Suisse Australia"),
each an affiliate of Credit Suisse, are sub-investment advisers to the Portfolio
(the "Sub-Advisers"). Credit Suisse U.K.'s and Credit Suisse Australia's
sub-investment advisory fees are paid by Credit Suisse out of Credit Suisse's
net investment advisory fee and are not paid by the Portfolio.

      Credit Suisse Asset Management Securities, Inc. ("CSAMSI"), an affiliate
of Credit Suisse, and SSB serve as co-administrators to the Portfolio.

      For its co-administrative services, CSAMSI currently receives a fee
calculated at an annual rate of 0.10% of the Portfolio's average daily net
assets. For the year ended December 31, 2005, co-administrative services fees
earned by CSAMSI were $115,628.

      For its co-administrative services, SSB receives a fee, exclusive of
out-of-pocket expenses, calculated in total for all the Credit Suisse
funds/portfolios

out-of-pocket expenses) were $91,017.

      In addition to serving as the Portfolio's co-administrator, CSAMSI

services to the Portfolio.

NOTE 4. LINE OF CREDIT

      The Portfolio, together with other funds/portfolios advised by Credit
Suisse (collectively, the "Participating Funds"), participates in a $75 million
committed, unsecured line of credit facility ("Credit Facility") for temporary
or emergency purposes with Deutsche Bank, A.G. as administrative agent and
syndication agent and SSB as operations agent. Under the terms of the Credit
Facility, the Participating Funds pay an aggregate commitment fee at a rate of
0.10% per annum on the average unused amount of the Credit Facility, which is
allocated among the Participating Funds in such manner as is determined by the
governing Boards of the Participating Funds. In addition, the Participating
Funds pay interest on borrowings at the Federal Funds rate plus 0.50%. At
December 31, 2005, and during the year ended December 31, 2005, the Portfolio
had no borrowings under the Credit Facility.

NOTE 5. PURCHASES AND SALES OF SECURITIES

      For the year ended December 31, 2005, purchases and sales of investment

the outstanding shares of the Portfolio was as follows:

of individual shareholders.

NOTE 8. FEDERAL INCOME TAXES

      Income and capital gain distributions are determined in accordance with
federal income tax regulations, which may differ from GAAP.

      The tax basis of components of distributable earnings differ from the
amounts reflected in the Statement of Assets and Liabilities by temporary
book/tax differences. These differences are primarily due to post-October
losses.

NOTE 8. FEDERAL INCOME TAXES

      At December 31, 2005, the components of distributable earnings on a tax
basis for the Portfolio was as follows:

      Accumulated net realized loss                   $ (48,201,486)
      Unrealized appreciation                            22,942,672

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

      At December 31, 2005, the Portfolio had capital loss carryforwards
available to offset possible future capital gains as follows:

               $23,847,620          $19,475,667         $4,878,199

      During the tax year ended December 31, 2005, the Portfolio utilized
$24,420,041 of the capital loss carryforward.

      Under current tax law, certain capital losses realized after October 31
within a taxable year may be deferred and treated as occurring on the first day
of the following tax year. For the tax period ended December 31, 2005 the
Portfolio elected to defer net losses arising between November 1, 2005 and
December 31, 2005 as follows:

                  CURRENCY                          CAPITAL
                ------------                       ---------
                   $11,454                            $--

      At December 31, 2005, the identified cost for federal income tax purposes,
as well as the gross unrealized appreciation from investments for those
securities having an excess of value over cost, gross unrealized depreciation
from investments for those securities having an excess of cost over value and
the net unrealized appreciation from investments were as follows: $143,770,823,
$26,060,414, $(3,122,399) and $ 22,938,015, respectively.

      At December 31, 2005, the Portfolio reclassified $440,844 to accumulated
net investment loss and $107,785 to accumulated net realized loss from
investments from paid-in capital, to adjust for current period permanent
book/tax differences which arose principally from differing book/tax treatments
of net operating losses, foreign currency transactions and security litigation.
Net assets were not affected by these reclassifications.

NOTE 9. CONTINGENCIES

      In the normal course of business, the Portfolio may provide general
indemnifications pursuant to certain contracts and organizational documents. The
Portfolio's maximum exposure under these arrangements is dependent on future
claims that may be made against the Portfolio and, therefore, cannot be
estimated; however, based on experience, the risk of loss from such claims is
considered remote.

CREDIT SUISSE TRUST - GLOBAL SMALL CAP PORTFOLIO
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Board of Trustees of Credit Suisse Trust and Shareholders of
Credit Suisse Trust - Global Small Cap Portfolio:

      In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Global Small Cap Portfolio (the
"Portfolio"), a portfolio of the Credit Suisse Trust, at December 31, 2005, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended and the financial highlights
for each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Portfolio's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements 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 are free of
material misstatement. An audit 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, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 2005 by
correspondence with the custodian and issuers, provide a reasonable basis for
our opinion.

CREDIT SUISSE TRUST - GLOBAL SMALL CAP PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED)
- --------------------------------------------------------------------------------

      In approving the Advisory and Sub-Advisory Agreements, the Board of
Trustees, including the Independent Trustees, considered the following factors
with respect to the Global Small Cap Portfolio (the "Portfolio"):

      INVESTMENT ADVISORY FEE RATES

      The Board reviewed and considered the contractual advisory fee rate of
1.25% paid by the Portfolio ("Contractual Advisory Fee") to Credit Suisse Asset
Management LLC ("Credit Suisse") in light of the extent and quality of the
advisory services provided by Credit Suisse or Credit Suisse Asset Management
Limited U.K. ("Credit Suisse U.K.") and Credit Suisse Asset Management Australia
("Credit Suisse Australia"). The Board also reviewed and considered the fee
waivers and/or expense reimbursement arrangements currently in place for the
Portfolio and considered the actual fee rate of 1.08% paid by the Portfolio
after taking waivers and reimbursements into account ("Net Advisory Fee"). The
Board acknowledged that the fee waivers and reimbursements could be discontinued
at any time. In addition, the Board noted that the compensation paid to Credit
Suisse U.K. and Credit Suisse Australia (collectively, the "Sub-Advisers") does
not increase the fees or expenses otherwise incurred by the Portfolio's
shareholders because the Sub-Advisers are paid by Credit Suisse, not the
Portfolio.

      Additionally, the Board received and considered information comparing each
Portfolio's Contractual Advisory Fee and Net Advisory Fee and the Portfolio's
overall expenses with those of funds in both the relevant expense group ("Peer
Group") and universe of funds (the "Universe") provided by Lipper Inc., an
independent provider of investment company data.

      NATURE, EXTENT AND QUALITY OF THE SERVICES UNDER THE ADVISORY AND
      SUB-ADVISORY AGREEMENTS

      The Board received and considered information regarding the nature, extent
and quality of services provided to the Portfolio by Credit Suisse under the
Advisory Agreement and by the Sub-Advisers under the Sub-Advisory Agreements.
The Board also noted information received at regular meetings throughout the
year related to the services rendered by Credit Suisse and the Sub-Advisers. The
Board reviewed background information about Credit Suisse and the Sub-Advisers,
including their respective Forms ADV. The Board considered the background and
experience of both Credit Suisse's and the Sub-Advisers' senior management and
the expertise of, and the amount of attention given to the Portfolio by, senior
personnel of Credit Suisse and the Sub-Advisers. With respect to the
Sub-Advisers, the Board also considered their expertise in managing the types of
global investments that the Portfolio utilizes in its investment strategy. In
addition, the Board reviewed the qualifications, backgrounds and
responsibilities of the portfolio management team primarily responsible for the
day-to-day portfolio management of the Portfolio and the extent of the resources
devoted to research and analysis of actual and potential investments. The Board
also received and considered information about the nature, extent and quality of
services and fee rates offered to other Credit Suisse clients for comparable
services.

CREDIT SUISSE TRUST - GLOBAL SMALL CAP PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      In approving the Sub-Advisory Agreements, the Board also considered the
benefits of retaining Credit Suisse's United Kingdom and Australian affiliates
given the increased complexity of the domestic and international securities
markets, specifically that retention of Credit Suisse U.K. and Credit Suisse
Australia expands the universe of companies and countries from which investment
opportunities could be sought and enhances the ability of the Portfolio to
obtain the best price and execution on trades in international markets.

      PORTFOLIO PERFORMANCE

      The Board received and considered the one-, two-, three-, four- and
five-year performance of the Portfolio, along with comparisons, for all
presented periods, both to the relevant performance group ("Performance Group")
and universe of funds ("Performance Universe") for the Portfolio. The Board was
provided with a description of the methodology used to arrive at the funds
included in the Performance Group and the Performance Universe.

      The Board reviewed information comparing the performance of various Credit
Suisse Funds to performance benchmarks that the Board had previously established
and progress that had been made in certain instances toward achieving those
benchmarks. The Board also reviewed comparisons between the Portfolio and its
identified benchmark over various time periods.

      CREDIT SUISSE PROFITABILITY

      The Board received and considered a profitability analysis of Credit
Suisse based on the fees payable under the Advisory Agreement for the Portfolio,
including any fee waivers or fee caps, as well as other relationships between
the Portfolio on the one hand and Credit Suisse affiliates on the other. The
Board received profitability information for the other funds in the Credit
Suisse family of funds.

      ECONOMIES OF SCALE

      The Board considered whether economies of scale in the provision of
services to the Portfolio were being passed along to the shareholders.
Accordingly, the Board considered whether alternative fee structures (such as
breakpoint fee structures) would be more appropriate or reasonable taking into
consideration economies of scale or other efficiencies that might accrue from
increases in the Portfolio's asset levels.

      OTHER BENEFITS TO CREDIT SUISSE

      The Board considered other benefits received by Credit Suisse, the
Sub-Advisers and their affiliates as a result of their relationships with the
Portfolio. Such benefits include, among others, research arrangements with
brokers who execute transactions on behalf of the Portfolio, administrative and
brokerage relationships with affiliates of Credit Suisse and the Sub-Advisers
and benefits potentially derived from an increase in Credit Suisse's and the
Sub-Advisers' businesses as a result of their relationship with the Portfolio
(such as the ability to market to shareholders other financial products offered
by Credit Suisse, the Sub-Advisers and their affiliates).

CREDIT SUISSE TRUST - GLOBAL SMALL CAP PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      The Board considered the standards applied in seeking best execution,
whether and to what extent soft dollar credits are sought and how any such
credits are utilized, any benefits that may be achieved by using an affiliated
broker and the existence of quality controls applicable to brokerage allocation
procedures. The Board also reviewed Credit Suisse's and the Sub-Advisers' method
for allocating portfolio investment opportunities among their advisory clients.

      CONCLUSIONS

      In selecting Credit Suisse and the Sub-Advisers, and approving the
Advisory Agreement and the investment advisory fee under such agreement and the
Sub-Advisory Agreements, the Board concluded that:

      o   Although both the Contractual and Net Advisory Fees were higher than
          the median of the Portfolio's Peer Group, the Board recognized that
          Credit Suisse has historically evidenced a willingness to waive fees.

      o   The Portfolio's one-, two- and three-year performance was above the
          Performance Universe's median and the highest in its Performance
          Group. The Portfolio's four-year performance was at the median for its
          Performance Group and below the median in its Performance Universe,
          while its five-year performance was the lowest in its Performance
          Group and below the median in its Performance Universe. The Board
          noted that Credit Suisse had made changes to the Portfolio's
          investment strategies and management team in response to performance
          issues previously raised by the Board.

      o   The Board was satisfied with the nature, extent and quality of the
          investment advisory services provided to the Portfolio by Credit
          Suisse and the Sub-Advisers and that, based on dialogue with
          management and counsel, the services provided by Credit Suisse under
          the Advisory Agreement and by the Sub-Advisers under the Sub-Advisory
          Agreements are typical of, and consistent with, those provided to
          mutual funds by other investment advisers.

      o   In light of the costs of providing investment management and other
          services to the Portfolio and Credit Suisse's ongoing commitment to
          the Portfolio and willingness to cap fees and expenses, the profits
          and other ancillary benefits that Credit Suisse and its affiliates
          received were considered reasonable.

      o   Credit Suisse's profitability based on fees payable under the Advisory
          Agreement was reasonable in light of the nature, extent and quality of
          the services provided to the Portfolio thereunder.

      o   In light of the relatively small size of the Portfolio and the amount
          of the Net Advisory Fees, the Portfolio's current fee structure
          (without breakpoints) was considered reasonable.

      No single factor reviewed by the Board was identified by the Board as the

independent legal counsel throughout the process.

CREDIT SUISSE TRUST -- INTERNATIONAL FOCUS PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

                                                                January 19, 2006

Dear Shareholder:

      For the 12 months ended December 31, 2005, Credit Suisse
Trust--International Focus Portfolio (the "Portfolio") had a gain of 17.56%, vs.
an increase of 17.12% for the Morgan Stanley Capital International All Country
World Ex-USA Index. 1

THE MARKETS: STRONG LOCALLY, BUT ERODED BY DOLLAR'S STRENGTH

      The year was a broadly positive one for equities globally, and most
foreign markets handily outpaced US stocks, at least in local currency terms.
European markets generally posted double-digit gains in euro terms, aided in
part by a relatively benign interest-rate backdrop. Japan was a notable
standout, up about 40% locally, amid signs that the world's second largest
economy may be poised for a sustainable recovery at long last. For dollar-based
investors, a decline in major currencies vs. the dollar reduced returns, though
most foreign markets still outperformed the US on that basis. Emerging markets
generally had the best dollar-based results in 2005.

      From a sector standpoint, materials, industrials and energy stocks were
the best performing areas of the market abroad. Consumer stocks had positive
absolute returns as a group but underperformed.

STRATEGIC REVIEW: GOOD STOCK SELECTION IN JAPAN

      The Portfolio outperformed its benchmark for the period. Factors that
aided the Portfolio's performance included strong stock selection in Japan.
Standouts represented a variety of sectors, including Komatsu (2.1% of the
Portfolio's net assets as of December 31, 2005), a manufacturer of construction
equipment with customers in Japan, the US, and China; and Yamada Denki (2.9% of
the Portfolio's net assets as of December 31, 2005), a retailer of electronics
goods that has improved its competitive position. Other good performers for the
Fund included Samsung Heavy (1.6% of the Portfolio's net assets as of December
31, 2005), a South Korean ship builder with an order book geared to liquid
natural gas (LNG) tankers.

      On the negative side, relatively speaking, the Portfolio's European
holdings as a group underperformed. Laggards included Royal Bank of Scotland
(1.4% of the Portfolio's net assets as of December 31, 2005), which was hampered
in part by acquisition worries, and Kingfisher, a UK "do it yourself" retailer.
We opted to eliminate the position in the period.

      In terms of noteworthy sector allocation, we ended the period with a
modest overweighting in the industrials area. We began the period with a large
overweighting in the sector, but reduced it on profit taking as certain holdings
reached our price target. Within health care, we went from being underweighted
to about neutrally positioned, adding to specific European pharmaceutical
holdings such as GlaxoSmithKline (2.1% of the Portfolio's net assets as of
December 31, 2005), based on our view of its valuation and product pipeline. We
also established a position in Novo Nordisk (2.0% of the Portfolio's net assets
as of December 31, 2005), a Denmark-based leader in diabetes treatments. During
the period we raised our exposure to the telecommunications sector, becoming
overweighted for the first time in over a year based on stock-specific factors.

      Going forward, we will maintain a value-based, bottom-up stock selection
process that seeks stocks we believe are trading at a discount, relative to
factors such as company earnings, assets or projected growth. Our focus is on
the world's major foreign equity markets, though we will maintain limited
exposure to emerging market companies when we deem them attractive.

      RETURNS REPRESENT PAST PERFORMANCE AND INCLUDE CHANGES IN SHARE PRICE AND
REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS. PAST PERFORMANCE CANNOT GUARANTEE
FUTURE RESULTS. THE CURRENT PERFORMANCE OF THE PORTFOLIO MAY BE LOWER OR HIGHER
THAN THE FIGURES SHOWN. RETURNS AND SHARE PRICE WILL FLUCTUATE, AND REDEMPTION
VALUE MAY BE MORE OR LESS THAN ORIGINAL COST. THE PERFORMANCE RESULTS DO NOT
REFLECT THE DEDUCTION OF TAXES THAT A SHAREHOLDER WOULD PAY ON PORTFOLIO
DISTRIBUTIONS OR THE REDEMPTION OF PORTFOLIO SHARES. PERFORMANCE INCLUDES THE
EFFECT OF DEDUCTING EXPENSES, BUT DOES NOT INCLUDE CHARGES AND EXPENSES
ATTRIBUTABLE TO ANY PARTICULAR VARIABLE CONTRACT OR PLAN. ACCORDINGLY, THE
PROSPECTUS OF THE SPONSORING PARTICIPATING INSURANCE COMPANY SEPARATE ACCOUNT OR
PLAN DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS SHOULD
BE CAREFULLY REVIEWED FOR INFORMATION ON RELEVANT CHARGES AND EXPENSES.
EXCLUDING THESE CHARGES AND EXPENSES FROM QUOTATIONS OF PERFORMANCE HAS THE
EFFECT OF INCREASING THE PERFORMANCE QUOTED, AND THE EFFECT OF THESE CHARGES
SHOULD BE CONSIDERED WHEN COMPARING PERFORMANCE TO THAT OF OTHER MUTUAL FUNDS.

ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

INFORMATION ABOUT YOUR PORTFOLIO'S EXPENSES

      As an investor of the Portfolio, you incur two types of costs: ongoing
expenses and transaction costs. Ongoing expenses include management fees,
distribution and service (12b-1) fees and other Portfolio expenses. Examples of
transaction costs include sales charges (loads), redemption fees and account
maintenance fees, which are not shown in this section and which would result in
higher total expenses. The following table is intended to help you understand
your ongoing expenses of investing in the Portfolio and to help you compare
these expenses with the ongoing expenses of investing in other mutual funds. The
table is based on an investment of $1,000 made at the beginning of the six month
period ended December 31, 2005.

      The table illustrates your Portfolio's expenses in two ways:

      o     ACTUAL PORTFOLIO RETURN. This helps you estimate the actual dollar
            amount of ongoing expenses paid on a $1,000 investment in the
            Portfolio using the Portfolio's actual return during the period. To
            estimate the expenses you paid over the period, simply divide your
            account value by $1,000 (for example, an $8,600 account value
            divided by $1,000 = 8.6), then multiply the result by the number in
            the "Expenses Paid per $1,000" line under the share class you hold.

      o     HYPOTHETICAL 5% PORTFOLIO RETURN. This helps you to compare your
            Portfolio's ongoing expenses with those of other mutual funds using
            the Portfolio's actual expense ratio and a hypothetical rate of
            return of 5% per year before expenses. Examples using a 5%
            hypothetical fund return may be found in the shareholder reports of
            other mutual funds. The hypothetical account values and expenses may
            not be used to estimate the actual ending account balance or
            expenses you paid for the period.

      Please note that the expenses shown in these tables are meant to highlight
your ongoing expenses only and do not reflect any transaction costs, such as
sales charges (loads) or redemption fees. If these transaction costs had been
included, your costs would have been higher. The "Expenses Paid per $1,000" line
of the tables is useful in comparing ongoing expenses only and will not help you
determine the relative total expenses of owning different funds.

ANNUALIZED EXPENSE RATIOS*                                                 1.45%

________________
*     EXPENSES ARE EQUAL TO THE PORTFOLIO'S ANNUALIZED EXPENSE RATIO MULTIPLIED
      BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY THE NUMBER OF
      DAYS IN THE MOST RECENT FISCAL HALF YEAR PERIOD, THEN DIVIDED BY 365.

      THE "EXPENSES PAID PER $1,000" AND THE "ANNUALIZED EXPENSE RATIOS" IN THE
      TABLES ARE BASED ON ACTUAL EXPENSES PAID BY THE PORTFOLIO DURING THE
      PERIOD, NET OF FEE WAIVERS AND/OR EXPENSE REIMBURSEMENTS. IF THOSE FEE
      WAIVERS AND/OR EXPENSE REIMBURSEMENTS HAD NOT BEEN IN EFFECT, THE
      PORTFOLIO'S ACTUAL EXPENSES WOULD HAVE BEEN HIGHER. EXPENSES DO NOT
      REFLECT ADDITIONAL CHARGES AND EXPENSES THAT ARE, OR MAY BE, IMPOSED UNDER
      THE VARIABLE CONTRACTS OR PLANS. SUCH CHARGES AND EXPENSES ARE DESCRIBED
      IN THE PROSPECTUS OF THE INSURANCE COMPANY SEPARATE ACCOUNT OR IN THE PLAN
      DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS. THE
      PORTFOLIO'S EXPENSES SHOULD BE CONSIDERED WITH THESE CHARGES AND EXPENSES
      IN EVALUATING THE OVERALL COST OF INVESTING IN THE SEPARATE ACCOUNT.

For more information, please refer to the Portfolio's prospectus.

CREDIT SUISSE TRUST -- INTERNATIONAL FOCUS PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
December 31, 2005
- --------------------------------------------------------------------------------

NOTE 1. ORGANIZATION

      Credit Suisse Trust (the "Trust") is an open-end management investment
company registered under the Investment Company Act of 1940, as amended, and
currently offers eight managed investment portfolios of which one, the
International Focus Portfolio (the "Portfolio"), is included in this report. The
Portfolio is a diversified investment fund that seeks long-term capital
appreciation. Shares of the Portfolio are not available directly to individual
investors but may be offered only through (a) variable annuity contracts and
variable life insurance contracts offered by separate accounts of certain
insurance companies and (b) tax-qualified pension and retirement plans. The
Portfolio may not be available in connection with a particular contract or plan.
The Trust was organized under the laws of The Commonwealth of Massachusetts as a
business trust on March 15, 1995.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      A) SECURITY VALUATION -- The net asset value of the Portfolio is
determined daily as of the close of regular trading on the New York Stock
Exchange, Inc. (the "Exchange") on each day the Exchange is open for business.
The Portfolio's equity investments are valued at market value, which is
generally determined using the closing price on the exchange or market on which
the security is primarily traded at the time of valuation (the "Valuation
Time"). If no sales are reported, equity investments are generally valued at the
most recent bid quotation as of the Valuation Time or at the lowest asked
quotation in the case of a short sale of securities. Debt securities with a
remaining maturity greater than 60 days are valued in accordance with the price
supplied by a pricing service, which may use a matrix, formula or other
objective method that takes into consideration market indices, yield curves and
other specific adjustments. Debt obligations that will mature in 60 days or less
are valued on the basis of amortized cost, which approximates market value,
unless it is determined that using this method would not represent fair value.
Investments in mutual funds are valued at the mutual fund's closing net asset
value per share on the day of valuation. Securities and other assets for which
market quotations are not readily available, or whose values have been
materially affected by events occurring before the Portfolio's Valuation Time
but after the close of the securities' primary markets, are valued at fair value
as determined in good faith by, or under the direction of, the Board of Trustees
under procedures established by the Board of Trustees. The Portfolio may utilize
a service provided by an independent

                                       19

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

third party which has been approved by the Board of Trustees to fair value
certain securities. When fair-value pricing is employed, the prices of
securities used by a fund to calculate its net asset value may differ from
quoted or published prices for the same securities.

      B) FOREIGN CURRENCY TRANSACTIONS -- The books and records of the Portfolio
are maintained in U.S. dollars. Transactions denominated in foreign currencies
are recorded at the current prevailing exchange rates. All assets and
liabilities denominated in foreign currencies are translated into U.S. dollar
amounts at the current exchange rate at the end of the period. Translation gains
or losses resulting from changes in the exchange rate during the reporting
period and realized gains and losses on the settlement of foreign currency
transactions are reported in the results of operations for the current period.
The Portfolio does not isolate that portion of realized gains and losses on
investments in EQUITY securities which is due to changes in the foreign exchange
rate from that which is due to changes in market prices of equity securities.
The Portfolio isolates that portion of realized gains and losses on investments
in DEBT securities which is due to changes in the foreign exchange rate from
that which is due to changes in market prices of debt securities.

      C) SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions
are accounted for on a trade date basis. Interest income is recorded on the
accrual basis. Dividends are recorded on the ex-dividend date. The cost of
investments sold is determined by use of the specific identification method for
both financial reporting and income tax purposes.

      D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net
investment income and distributions of net realized capital gains, if any, are
declared and paid at least annually. However, to the extent that a net realized
capital gain can be reduced by a capital loss carryforward, such gain will not
be distributed. Income and capital gain distributions are determined in
accordance with federal income tax regulations, which may differ from accounting
principles generally accepted in the United States of America ("GAAP").

      E) FEDERAL INCOME TAXES -- No provision is made for federal taxes as it is
the Trust's intention to have the Portfolio continue to qualify for and elect
the tax treatment applicable to regulated investment companies under the

distributions to its shareholders, which will be sufficient to relieve it from
federal income and excise taxes.

      F) USE OF ESTIMATES -- The preparation of financial statements in
conformity with GAAP 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 revenues and expenses during the reporting period.
Actual results could differ from these estimates.

      G) SHORT-TERM INVESTMENTS -- The Portfolio, together with other
funds/portfolios advised by Credit Suisse Asset Management, LLC ("Credit
Suisse"), an indirect, wholly-owned subsidiary of Credit Suisse Group, pools
available cash into either a short-term variable rate time deposit issued by
State Street Bank and Trust Company ("SSB"), the Portfolio's custodian, or a
money market fund advised by Credit Suisse. The short-term time deposit issued
by SSB is a variable rate account classified as a short-term investment.

      H) FORWARD FOREIGN CURRENCY CONTRACTS -- The Portfolio may enter into
forward foreign currency contracts for the purchase or sale of a specific
foreign currency at a fixed price on a future date. Risks may arise upon
entering into these contracts from the potential inability of counterparties to
meet the terms of their contracts and from unanticipated movements in the value
of a foreign currency. The Portfolio will enter into forward foreign currency
contracts primarily for hedging purposes. Forward foreign currency contracts are
adjusted by the daily forward exchange rate of the underlying currency and any
gains or losses are recorded for financial statement purposes as unrealized
until the contract settlement date or an offsetting position is entered into. At
December 31, 2005, the Portfolio had no open forward foreign currency contracts.

      I) SECURITIES LENDING -- Loans of securities are required at all times to
be secured by collateral at least equal to 102% of the market value of domestic
securities on loan (including any accrued interest thereon) and 105% of the
market value of foreign securities on loan (including any accrued interest
thereon). Cash collateral received by the Portfolio in connection with
securities lending activity may be pooled together with cash collateral for
other funds/portfolios advised by Credit Suisse and may be invested in a variety
of investments, including certain Credit Suisse-advised funds, funds advised by

                                       21

SSB, the Portfolio's securities lending agent, or money market instruments.
However, in the event of default or bankruptcy by the other party to the
agreement, realization and/or retention of the collateral may be subject to
legal proceedings.

      SSB has been engaged by the Portfolio to act as the Portfolio's securities
lending agent. The Portfolio's securities lending arrangement provides that the
Portfolio and SSB will share the net income earned from the securities lending
activities. During the year ended December 31, 2005, total earnings from the
Portfolio's investment in cash collateral received in connection with securities
lending arrangements was $668,397, of which $552,755 was rebated to borrowers
(brokers). The Portfolio retained $81,179 in income from the cash collateral
investment, and SSB, as lending agent, was paid $34,463. The Portfolio may also
be entitled to certain minimum amounts of income from its securities lending
activities. Securities lending income is accrued as earned.

      J) OTHER -- The Portfolio may invest in securities of foreign countries
and governments which involve certain risks in addition to those inherent in
domestic investments. Such risks generally include, among others, currency risk
(fluctuations in currency exchange rates), information risk (key information may
be inaccurate or unavailable) and political risk (expropriation, nationalization
or the imposition of capital or currency controls or punitive taxes). Other
risks of investing in foreign securities include liquidity and valuation risks.

      The Portfolio may be subject to taxes imposed by countries in which it
invests with respect to its investments in issuers existing or operating in such
countries. Such taxes are generally based on income earned or repatriated and
capital gains realized on the sale of such investments. The Portfolio accrues
such taxes when the related income or gains are earned.

      The Portfolio may invest up to 15% of its net assets in non-publicly
traded securities. Non-publicly traded securities may be less liquid than
publicly traded securities. Although these securities may be resold in privately
negotiated transactions, the prices realized from such sales could differ from
the price originally paid by the Portfolio or the current carrying values, and
the difference could be material.

out-of-pocket expenses, calculated in total for all the Credit Suisse
funds/portfolios co-administered by SSB and allocated based upon relative
average net assets of each fund/portfolio, subject to an annual minimum fee. For
the year ended December 31, 2005, co-administrative services fees earned by SSB
(including out-of-pocket expenses) were $69,515.

      In addition to serving as the Portfolio's co-administrator, CSAMSI

Facility, the Participating Funds pay an aggregate commitment fee at a rate of
0.10% per annum on the average unused amount of the Credit Facility, which is
allocated among the Participating Funds in such manner as is determined by the
governing Boards of the Participating Funds. In addition, the Participating
Funds pay interest on borrowings at the Federal Funds rate plus 0.50%. At
December 31, 2005, and during the year ended December 31, 2005, the Portfolio
had no borrowings under the Credit Facility.

NOTE 5. PURCHASES AND SALES OF SECURITIES

      On December 31, 2005, the number of shareholders that held 5% or more of
the outstanding shares of the Portfolio was as follows:

                   NUMBER OF              APPROXIMATE PERCENTAGE
                  SHAREHOLDERS            OF OUTSTANDING SHARES

      Some of the shareholders are omnibus accounts, which hold shares on behalf
of individual shareholders.

NOTE 7. FEDERAL INCOME TAXES

      Income and capital gain distributions are determined in accordance with
federal income tax regulations, which may differ from GAAP.

NOTE 7. FEDERAL INCOME TAXES

      The tax character of dividends paid during the years ended December 31,
2005, and 2004, respectively, for the Portfolio were as follows:

                                  ORDINARY INCOME
                               ----------------------
                                 2005          2004
                               --------     ---------
                               $739,766      $824,282

      The tax basis of components of distributable earnings differ from the
amounts reflected in the Statement of Assets and Liabilities by temporary
book/tax differences. These differences are primarily due to losses deferred on
wash sales and deferral of post-October losses.

      At December 31, 2005, the components of distributable earnings on a tax
basis for the Portfolio were as follows:

        Undistributed net investment income            $     967,038
        Accumulated net realized loss                   (112,870,927)
        Unrealized appreciation                           22,648,692
        Deferral of post-October currency losses             (21,062)
                                                       -------------

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

      At December 31, 2005, the Portfolio had capital loss carryforwards
available to offset possible future capital gains as follows:

                                   EXPIRES DECEMBER 31,

                          $72,374,131   $37,413,453   $3,083,343

      During the tax year ended December 31, 2005, the Portfolio utilized
$7,552,063 of the capital loss carryforward.

      At December 31, 2005, the identified cost for federal income tax purposes,
as well as the gross unrealized appreciation from investments for those
securities having an excess of value over cost, gross unrealized depreciation
from investments for those securities having an excess of cost over value and
the net unrealized appreciation from investments were as follows: $85,923,470,
$23,371,476, $(741,566) and $22,629,910, respectively.

      At December 31, 2005, the Portfolio reclassified $57,737 from
undistributed net investment income to accumulated net realized loss from
investments, to adjust for current period permanent book/tax differences which
arose principally from differing book/tax treatments of foreign currency
transactions and security litigation. Net assets were not affected by these
reclassifications.

NOTE 8. CONTINGENCIES

      In the normal course of business, the Portfolio may provide general
indemnifications pursuant to certain contracts and organizational documents. The
Portfolio's maximum exposure under these arrangements is dependent on future
claims that may be made against the Portfolio and, therefore, cannot be
estimated; however, based on experience, the risk of loss from such claims is
considered remote.

CREDIT SUISSE TRUST -- INTERNATIONAL FOCUS PORTFOLIO
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Board of Trustees of Credit Suisse Trust and Shareholders of Credit
Suisse Trust - International Focus Portfolio:

      In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of International Focus Portfolio (the
"Portfolio"), a portfolio of the Credit Suisse Trust, at December 31, 2005, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended and the financial highlights
for each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Portfolio's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements 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 are free of
material misstatement. An audit 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, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 2005 by
correspondence with the custodian, provide a reasonable basis for our opinion.

CREDIT SUISSE TRUST -- INTERNATIONAL FOCUS PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED)
- --------------------------------------------------------------------------------

      In approving the Advisory and Sub-Advisory Agreements, the Board of
Trustees, including the Independent Trustees, considered the following factors
with respect to the International Focus Portfolio (the "Portfolio"):

      INVESTMENT ADVISORY FEE RATES

      The Board reviewed and considered the contractual advisory fee rate of
1.00% paid by the Portfolio ("Contractual Advisory Fee") to Credit Suisse Asset
Management LLC ("Credit Suisse") in light of the extent and quality of the
advisory services provided by Credit Suisse or Credit Suisse Asset Management
Limited U.K. ("Credit Suisse U.K.") and Credit Suisse Asset Management Limited
Australia ("Credit Suisse Australia"). The Board noted that the compensation
paid to Credit Suisse U.K. and Credit Suisse Australia (collectively, the
"Sub-Advisers") does not increase the fees or expenses otherwise incurred by the
Portfolio's shareholders because the Sub-Advisers are paid by Credit Suisse, not
the Portfolio.

      Additionally, the Board received and considered information comparing the
Portfolio's Contractual Advisory Fee and the Portfolio's overall expenses with
those of funds in both the relevant expense group ("Peer Group") and universe of
funds (the "Universe") provided by Lipper Inc., an independent provider of
investment company data.

      NATURE, EXTENT AND QUALITY OF THE SERVICES UNDER THE ADVISORY AND
SUB-ADVISORY AGREEMENTS

      The Board received and considered information regarding the nature, extent
and quality of services provided to the Portfolio by Credit Suisse under the
Advisory Agreement and by the Sub-Advisers under the Sub-Advisory Agreements.
The Board also noted information received at regular meetings throughout the
year related to the services rendered by Credit Suisse and the Sub-Advisers. The
Board reviewed background information about Credit Suisse and the Sub-Advisers,
including their respective Form ADV. The Board considered the background and
experience of both Credit Suisse's and the Sub-Advisers' senior management and
the expertise of, and the amount of attention given to the Portfolio by, senior
personnel of Credit Suisse and the Sub-Advisers. With respect to the
Sub-Advisers, the Board also considered their expertise in managing the types of
global investments that the Portfolio utilizes in its investment strategy. In
addition, the Board reviewed the qualifications, backgrounds and
responsibilities of the portfolio management team primarily responsible for the
day-to-day portfolio management of the Portfolio and the extent of the resources
devoted to research and analysis of actual and potential

                                       28

- --------------------------------------------------------------------------------

investments. The Board also received and considered information about the
nature, extent and quality of services and fee rates offered to other Credit
Suisse clients for comparable services.

      In approving the Sub-Advisory Agreements, the Board also considered the
benefits of retaining Credit Suisse's United Kingdom and Australian affiliates
given the increased complexity of the domestic and international securities
markets, specifically that retention of Credit Suisse U.K. and Credit Suisse
Australia expands the universe of companies and countries from which investment
opportunities could be sought and enhances the ability of the Portfolio to
obtain the best price and execution on trades in international markets.

      PORTFOLIO PERFORMANCE

      The Board received and considered the one-, two-, three-, four-, five- and
ten-year performance of the Portfolio, along with comparisons, for all presented
periods, both to the relevant performance group ("Performance Group") and
universe of funds ("Performance Universe") for the Portfolio. The Board was
provided with a description of the methodology used to arrive at the funds
included in the Performance Group and the Performance Universe.

      The Board reviewed information comparing the performance of various Credit
Suisse Funds to performance benchmarks that the Board had previously established
and progress that had been made in certain instances toward achieving those
benchmarks. The Board also reviewed comparisons between the Portfolio and its
identified benchmark over various time periods.

      CREDIT SUISSE PROFITABILITY

      The Board received and considered a profitability analysis of Credit
Suisse based on the fees payable under the Advisory Agreement for the Portfolio,
including other relationships between the Portfolio on the one hand and Credit
Suisse affiliates on the other. The Board received profitability information for
the other funds in the Credit Suisse family of funds.

      ECONOMIES OF SCALE

      The Board considered whether economies of scale in the provision of
services to the Portfolio were being passed along to the shareholders.
Accordingly, the Board considered whether alternative fee structures (such as
breakpoint fee structures) would be more appropriate or reasonable taking into
consideration economies of scale or other efficiencies that might accrue from
increases in the Portfolio's asset levels.

                                       29




CREDIT SUISSE TRUST -- INTERNATIONAL FOCUS PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      OTHER BENEFITS TO CREDIT SUISSE

      The Board considered other benefits received by Credit Suisse, the
Sub-Advisers and their affiliates as a result of their relationships with the
Portfolio. Such benefits include, among others, research arrangements with
brokers who execute transactions on behalf of the Portfolio, administrative and
brokerage relationships with affiliates of Credit Suisse and the Sub-Advisers
and benefits potentially derived from an increase in Credit Suisse's and the
Sub-Advisers' businesses as a result of their relationship with the Portfolio
(such as the ability to market to shareholders other financial products offered
by Credit Suisse, the Sub-Advisers and their affiliates).

      The Board considered the standards applied in seeking best execution,
whether and to what extent soft dollar credits are sought and how any such
credits are utilized, any benefits that may be achieved by using an affiliated
broker and the existence of quality controls applicable to brokerage allocation
procedures. The Board also reviewed Credit Suisse's and the Sub-Advisers' method
for allocating portfolio investment opportunities among their advisory clients.

      CONCLUSIONS

      In selecting Credit Suisse and the Sub-Advisers, and approving the
Advisory Agreement and the investment advisory fee under such agreement and the
Sub-Advisory Agreements, the Board concluded that:

      o     Both the Contractual Advisory Fee of 1.00% and the net advisory fee
            of 0.95% (when the voluntary fee waiver described below is taken
            into account) were higher than the median of the Portfolio's Peer
            Group. The Board considered the fee to be reasonable taking the fee
            waiver and the relatively small size of the Portfolio into account.

      o     The Portfolio's performance was in the fourth or fifth quintile of
            its Performance Group for all periods except the one-year
            performance, where it ranked in the second quintile. The Portfolio's
            performance was in the fourth or fifth quintile of its Performance
            Universe for all periods except the one-year performance, where it
            ranked in the third quintile. The Board noted that the Portfolio's
            performance for the one-, two-, three-, four- and five-year periods
            was above or reasonably close, within one standard deviation, of the
            Performance Universe's and Performance Group's median, while the
            Portfolio's ten-year performance was within two standard deviations
            below the median for its Performance Group and Performance Universe.
            The Board had previously identified the need to

                                       30




CREDIT SUISSE TRUST -- INTERNATIONAL FOCUS PORTFOLIO

            address the Portfolio's performance, and noted that Credit Suisse
            had taken steps in response to performance issues raised by the
            Board. After discussion with the Board, Credit Suisse had agreed to
            a one-year voluntary fee reduction of five basis points. The Board
            would continue to monitor steps undertaken by Credit Suisse to
            improve performance.

      o     Aside from performance (as described above), the Board was satisfied
            with the nature, extent and quality of the investment advisory
            services provided to the Portfolio by Credit Suisse and the
            Sub-Advisers and that, based on dialogue with management and
            counsel, the services provided by Credit Suisse under the Advisory
            Agreement and by the Sub-Advisers under the Sub-Advisory Agreements
            are typical of, and consistent with, those provided to mutual funds
            by other investment advisers. The Board understood that Credit
            Suisse had addressed or was in the process of addressing any
            performance issues.

      o     In light of the costs of providing investment management and other
            services to the Portfolio and Credit Suisse's ongoing commitment to
            the Portfolio, the profits and other ancillary benefits that Credit
            Suisse and its affiliates received were considered reasonable.

      o     Credit Suisse's profitability based on fees payable under the
            Advisory Agreement was reasonable in light of the nature, extent and
            quality of the services provided to the Portfolio thereunder.

      o     In light of the relatively small size of the Portfolio and the
            amount of the Contractual Advisory Fees, the Portfolio's current fee
            structure (without breakpoints) was considered reasonable.

      No single factor reviewed by the Board was identified by the Board as the
principal factor in determining whether to approve the Advisory Agreement and

CREDIT SUISSE TRUST -- SMALL CAP GROWTH PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

                                                                January 19, 2006

Dear Shareholder:

      For the 12 months ended December 31, 2005, Credit Suisse Trust--Small Cap
Growth Portfolio (the "Portfolio") had a loss of 2.68%, vs. an increase of 4.15%
for the Russell 2000(R) Growth Index. 1

THE MARKET: POSITIVE DESPITE RISING ENERGY COSTS, INTEREST RATES

      The period was an overall positive one for equities. Stocks initially
struggled, but rallied into the summer, aided by benign inflation data and good
earnings reports from a number of visible companies. To be sure, headwinds were
ever-present, notably in the form of hurricane activity, surging energy prices
and a Federal Reserve that continued to raise short-term interest rates in small
but steady increments. In the face of all this, the economy nonetheless appeared
resilient, at least as of late 2005: Third-quarter GDP growth was reported at an
annualized rate of 4.1%, the tenth consecutive quarter of 3% or greater growth.
The earnings backdrop remained generally supportive late in the year.

      In the market, high energy prices helped drive the outperformance of
energy related stocks, which, despite some late-period weakness, outpaced all
other economic sectors in the period. This was reflected in the outperformance
of value stocks over growth stocks, as energy companies comprise a relatively
large share of the value universe. Mid-capitalization stocks generally
outperformed both large- and small-cap stocks for the period.

STRATEGIC REVIEW: TECHNOLOGY HOLDINGS OUTPERFORM, BUT HEALTH CARE DISAPPOINTS

      The Portfolio underperformed its benchmark in the period, which we
attribute in large measure to stock selection in the health care sector. This
included sizable declines by Amerigroup and Molina Healthcare, two managed care
companies with significant Medicaid patient exposure. We opted to eliminate
these two positions late in the period based on their unexpectedly high costs
and dimmer intermediate-term prospects. The Portfolio's consumer discretionary
holdings also underperformed. Greenfield Online (0.5% of the Portfolio's net
assets as of December 31, 2005), an internet marketing services company, fell
amid disappointing demand for its information management services.

- --------------------------------------------------------------------------------

      On the positive side, factors that aided the Portfolio included good stock
selection in the technology sector, where the Portfolio's holdings collectively
advanced despite a generally lackluster year for small-cap technology stocks.
Trident Microsystems and Genesis Microchip were among the standouts, and we
eliminated the positions based on valuation. Both companies provide graphics
manipulation tools used in markets such as video games and high-definition
television. The Portfolio's financial services stocks also had good performance
in absolute as well as relative terms.

      Going forward, we will continue to seek to identify companies with
attractive capital-growth potential. Our stock-selection process emphasizes
companies we believe to have accelerating earnings, improving fundamentals,
competent management and compelling business models, and includes companies
still in their developmental stage as well as older companies that appear to be
entering a new stage of growth. Our general strategy is focused on a company's
longer-term prospects, though we also attempt to identify stocks we feel are
poised to benefit from specific market catalysts over the nearer term.

      RETURNS REPRESENT PAST PERFORMANCE AND INCLUDE CHANGES IN SHARE PRICE AND
REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS. PAST PERFORMANCE CANNOT GUARANTEE
FUTURE RESULTS. THE CURRENT PERFORMANCE OF THE PORTFOLIO MAY BE LOWER OR HIGHER
THAN THE FIGURES SHOWN. RETURNS AND SHARE PRICE WILL FLUCTUATE, AND REDEMPTION
VALUE MAY BE MORE OR LESS THAN ORIGINAL COST. THE PERFORMANCE RESULTS DO NOT
REFLECT THE DEDUCTION OF TAXES THAT A SHAREHOLDER WOULD PAY ON PORTFOLIO
DISTRIBUTIONS OR THE REDEMPTION OF PORTFOLIO SHARES. PERFORMANCE INCLUDES THE
EFFECT OF DEDUCTING EXPENSES, BUT DOES NOT INCLUDE CHARGES AND EXPENSES
ATTRIBUTABLE TO ANY PARTICULAR VARIABLE CONTRACT OR PLAN. ACCORDINGLY, THE
PROSPECTUS OF THE SPONSORING PARTICIPATING INSURANCE COMPANY SEPARATE ACCOUNT OR
PLAN DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS SHOULD
BE CAREFULLY REVIEWED FOR INFORMATION ON RELEVANT CHARGES AND EXPENSES.
EXCLUDING THESE CHARGES AND EXPENSES FROM QUOTATIONS OF PERFORMANCE HAS THE
EFFECT OF INCREASING THE PERFORMANCE QUOTED, AND THE EFFECT OF THESE CHARGES
SHOULD BE CONSIDERED WHEN COMPARING PERFORMANCE TO THAT OF OTHER MUTUAL FUNDS.

CREDIT SUISSE TRUST -- SMALL CAP GROWTH PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

INFORMATION ABOUT YOUR PORTFOLIO'S EXPENSES

      As an investor of the Portfolio, you incur two types of costs: ongoing
expenses and transaction costs. Ongoing expenses include management fees,
distribution and service (12b-1) fees and other Portfolio expenses. Examples of
transaction costs include sales charges (loads), redemption fees and account
maintenance fees, which are not shown in this section and which would result in
higher total expenses. The following table is intended to help you understand
your ongoing expenses of investing in the Portfolio and to help you compare
these expenses with the ongoing expenses of investing in other mutual funds. The
table is based on an investment of $1,000 made at the beginning of the six month
period ended December 31, 2005.

      The table illustrates your Portfolio's expenses in two ways:

      o     ACTUAL PORTFOLIO RETURN. This helps you estimate the actual dollar
            amount of ongoing expenses paid on a $1,000 investment in the
            Portfolio using the Portfolio's actual return during the period. To
            estimate the expenses you paid over the period, simply divide your
            account value by $1,000 (for example, an $8,600 account value
            divided by $1,000 = 8.6), then multiply the result by the number in
            the "Expenses Paid per $1,000" line under the share class you hold.

      o     HYPOTHETICAL 5% PORTFOLIO RETURN. This helps you to compare your
            Portfolio's ongoing expenses with those of other mutual funds using
            the Portfolio's actual expense ratio and a hypothetical rate of
            return of 5% per year before expenses. Examples using a 5%
            hypothetical fund return may be found in the shareholder reports of
            other mutual funds. The hypothetical account values and expenses may
            not be used to estimate the actual ending account balance or
            expenses you paid for the period.

      Please note that the expenses shown in these tables are meant to highlight
your ongoing expenses only and do not reflect any transaction costs, such as
sales charges (loads) or redemption fees. If these transaction costs had been
included, your costs would have been higher. The "Expenses Paid per $1,000" line
of the tables is useful in comparing ongoing expenses only and will not help you
determine the relative total expenses of owning different funds.

______________

*     EXPENSES ARE EQUAL TO THE PORTFOLIO'S ANNUALIZED EXPENSE RATIO MULTIPLIED
      BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY THE NUMBER OF
      DAYS IN THE MOST RECENT FISCAL HALF YEAR PERIOD, THEN DIVIDED BY 365.

      THE "EXPENSES PAID PER $1,000" AND THE "ANNUALIZED EXPENSE RATIOS" IN THE
      TABLES ARE BASED ON ACTUAL EXPENSES PAID BY THE PORTFOLIO DURING THE
      PERIOD, NET OF FEE WAIVERS AND/OR EXPENSE REIMBURSEMENTS. IF THOSE FEE
      WAIVERS AND/OR EXPENSE REIMBURSEMENTS HAD NOT BEEN IN EFFECT, THE
      PORTFOLIO'S ACTUAL EXPENSES WOULD HAVE BEEN HIGHER. EXPENSES DO NOT
      REFLECT ADDITIONAL CHARGES AND EXPENSES THAT ARE, OR MAY BE, IMPOSED UNDER
      THE VARIABLE CONTRACTS OR PLANS. SUCH CHARGES AND EXPENSES ARE DESCRIBED
      IN THE PROSPECTUS OF THE INSURANCE COMPANY SEPARATE ACCOUNT OR IN THE PLAN
      DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS. THE
      PORTFOLIO'S EXPENSES SHOULD BE CONSIDERED WITH THESE CHARGES AND EXPENSES
      IN EVALUATING THE OVERALL COST OF INVESTING IN THE SEPARATE ACCOUNT.

For more information, please refer to the Portfolio's prospectus.

CREDIT SUISSE TRUST -- SMALL CAP GROWTH PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
December 31, 2005
- --------------------------------------------------------------------------------

NOTE 1. ORGANIZATION

      Credit Suisse Trust (the "Trust") is an open-end management investment
company registered under the Investment Company Act of 1940, as amended, and
currently offers eight managed investment portfolios of which one, the Small Cap
Growth Portfolio (the "Portfolio"), is included in this report. The Portfolio is
a diversified investment fund that seeks capital growth. Shares of the Portfolio
are not available directly to individual investors but may be offered only
through (a) variable annuity contracts and variable life insurance contracts
offered by separate accounts of certain insurance companies and (b)
tax-qualified pension and retirement plans. The Portfolio may not be available
in connection with a particular contract or plan. The Trust was organized under
the laws of the Commonwealth of Massachusetts as a business trust on March 15,
1995.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      A) SECURITY VALUATION -- The net asset value of the Portfolio is
determined daily as of the close of regular trading on the New York Stock
Exchange, Inc. (the "Exchange") on each day the Exchange is open for business.
The Portfolio's equity investments are valued at market value, which is
generally determined using the closing price on the exchange or market on which
the security is primarily traded at the time of valuation (the "Valuation
Time"). If no sales are reported, equity investments are generally valued at the
most recent bid quotation as of the Valuation Time or at the lowest asked
quotation in the case of a short sale of securities. Debt securities with a
remaining maturity greater than 60 days are valued in accordance with the price
supplied by a pricing service, which may use a matrix, formula or other
objective method that takes into consideration market indices, yield curves and
other specific adjustments. Debt obligations that will mature in 60 days or less
are valued on the basis of amortized cost, which approximates market value,
unless it is determined that using this method would not represent fair value.
Investments in mutual funds are valued at the mutual fund's closing net asset
value per share on the day of valuation. Securities and other assets for which
market quotations are not readily available, or whose values have been
materially affected by events occurring before the Portfolio's Valuation Time
but after the close of the securities' primary markets, are valued at fair value
as determined in good faith by, or under the direction of, the Board of Trustees
under procedures established by the Board of Trustees. The Portfolio may utilize
a service provided by an independent

                                       16

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

third party which has been approved by the Board of Trustees to fair value
certain securities. When fair-value pricing is employed, the prices of
securities used by a fund to calculate its net asset value may differ from
quoted or published prices for the same securities.

      B) SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions
are accounted for on a trade date basis. Interest income is recorded on the
accrual basis. Dividends are recorded on the ex-dividend date. The cost of
investments sold is determined by use of the specific identification method for
both financial reporting and income tax purposes.

      C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net
investment income and distributions of net realized capital gains, if any, are
declared and paid at least annually. However, to the extent that a net realized
capital gain can be reduced by a capital loss carryforward, such gain will not
be distributed. Income and capital gain distributions are determined in
accordance with federal income tax regulations, which may differ from accounting
principles generally accepted in the United States of America ("GAAP").

      D) FEDERAL INCOME TAXES -- No provision is made for federal taxes as it is
the Trust's intention to have the Portfolio continue to qualify for and elect
the tax treatment applicable to regulated investment companies under the
Internal Revenue Code of 1986, as amended, and to make the requisite
distributions to its shareholders, which will be sufficient to relieve it from
federal income and excise taxes.

      E) USE OF ESTIMATES -- The preparation of financial statements in
conformity with GAAP 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 revenues and expenses during the reporting period.
Actual results could differ from these estimates.

      F) SHORT-TERM INVESTMENTS -- The Portfolio, together with other
funds/portfolios advised by Credit Suisse Asset Management, LLC ("Credit
Suisse"), an indirect, wholly-owned subsidiary of Credit Suisse Group, pools
available cash into either a short-term variable rate time deposit issued by
State Street Bank and Trust Company ("SSB"), the Portfolio's custodian, or a
money

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

market fund advised by Credit Suisse. The short-term time deposit issued by SSB
is a variable rate account classified as a short-term investment.

      G) SECURITIES LENDING -- Loans of securities are required at all times to
be secured by collateral at least equal to 102% of the market value of domestic
securities on loan (including any accrued interest thereon) and 105% of the
market value of foreign securities on loan (including any accrued interest
thereon). Cash collateral received by the Portfolio in connection with
securities lending activity may be pooled together with cash collateral for
other funds/portfolios advised by Credit Suisse and may be invested in a variety
of investments, including certain Credit Suisse-advised funds, funds advised by
SSB, the Portfolio's securities lending agent, or money market instruments.
However, in the event of default or bankruptcy by the other party to the
agreement, realization and/or retention of the collateral may be subject to
legal proceedings.

      SSB has been engaged by the Portfolio to act as the Portfolio's securities
lending agent. The Portfolio's securities lending arrangement provides that the
Portfolio and SSB will share the net income earned from the securities lending
activities. During the year ended December 31, 2005, total earnings from the
Portfolio's investment in cash collateral received in connection with securities
lending arrangements was $5,791,276, of which $5,295,748 was rebated to
borrowers (brokers). The Portfolio retained $347,679 in income from the cash
collateral investment, and SSB, as lending agent, was paid $147,849. The
Portfolio may also be entitled to certain minimum amounts of income from its
securities lending activities. Securities lending income is accrued as earned.

      H) OTHER -- The Portfolio may invest up to 15% of its net assets in
non-publicly traded securities. Non-publicly traded securities may be less
liquid than publicly traded securities. Although these securities may be resold
in privately negotiated transactions, the prices realized from such sales could
differ from the price originally paid by the Portfolio or the current carrying
values, and the difference could be material.

NOTE 3. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

      Credit Suisse serves as investment adviser for the Portfolio. For its
investment advisory services, Credit Suisse is entitled to receive a fee from
the Portfolio at an annual rate of 0.90% of the average daily net assets of the

earned were $5,795,796.

      Credit Suisse Asset Management Securities, Inc. ("CSAMSI"), an affiliate
of Credit Suisse, and SSB serve as co-administrators to the Portfolio.

      For its co-administrative services, CSAMSI currently receives a fee
calculated at an annual rate of 0.10% of the average daily net assets of the
Portfolio. For the year ended December 31, 2005, co-administrative services fees
earned by CSAMSI were $643,977.

      For its co-administrative services, SSB receives a fee, exclusive of
out-of-pocket expenses, calculated in total for all the Credit Suisse
funds/portfolios co-administered by SSB and allocated based upon relative
average net assets of each fund/portfolio, subject to an annual minimum fee. For
the year ended December 31, 2005, co-administrative services fees earned by SSB
(including out-of-pocket expenses) were $438,669.

      In addition to serving as the Portfolio's co-administrator, CSAMSI
currently serves as distributor of the Portfolio's shares without compensation.

      Merrill Corporation ("Merrill"), an affiliate of Credit Suisse, has been
engaged by the Portfolio to provide certain financial printing and fulfillment
services. For the year ended December 31, 2005, Merrill was paid $7,504 for its
services to the Portfolio.

NOTE 4. LINE OF CREDIT

      The Portfolio, together with other funds/portfolios advised by Credit
Suisse (collectively, the "Participating Funds"), participates in a $75 million
committed, unsecured line of credit facility ("Credit Facility") for temporary
or emergency purposes with Deutsche Bank, A.G. as administrative agent and
syndication agent and SSB as operations agent. Under the terms of the Credit
Facility, the Participating Funds pay an aggregate commitment fee at a rate of
0.10% per annum on the average unused amount of the Credit Facility, which is
allocated among the Participating Funds in such manner as is determined by the
governing Boards of the Participating Funds. In addition, the Participating
Funds pay interest on borrowings at the Federal Funds rate plus 0.50%. At
December 31, 2005 and during the year ended December 31, 2005, the Portfolio had
no borrowings under the Credit Facility.

      The Trust is authorized to issue an unlimited number of full and
fractional shares of beneficial interest, $.001 par value per share.

      On December 31, 2005, the number of shareholders that held 5% or more of
the outstanding shares of the Portfolio was as follows:

                SHAREHOLDERS            OF OUTSTANDING SHARES

                      3                          86%

      Some of the shareholders are omnibus accounts, which hold shares on behalf
of individual shareholders.

NOTE 7. FEDERAL INCOME TAXES

      Income and capital gain distributions are determined in accordance with
federal income tax regulations, which may differ from GAAP.

      The tax basis of components of distributable earnings differ from the
amounts reflected in the Statement of Assets and Liabilities by temporary
book/tax differences. These differences are primarily due to losses deferred on
wash sales.

      At December 31, 2005, the components of distributable earnings on a tax
basis for the Portfolio were as follows:

         Accumulated net realized loss            $(125,618,971)
         Unrealized appreciation                  $  25,102,011

NOTE 7. FEDERAL INCOME TAXES

      At December 31, 2005, the Portfolio had capital loss carryforwards
available to offset possible future capital gains as follows:

                              EXPIRES DECEMBER 31,
                    --------------------------------------

                     $27,132,018   $93,228,766   $5,258,187

      During the tax year ended December 31, 2005, the Portfolio utilized
$69,726,382 of the capital loss carryforward.

      At December 31, 2005, the identified cost for federal income tax purposes,
as well as the gross unrealized appreciation from investments for those
securities having an excess of value over cost, gross unrealized depreciation
from investments for those securities having an excess of cost over value and
the net unrealized appreciation from investments were as follows: $694,947,620
$80,887,208 ($55,785,197) and $25,102,011, respectively.

      At December 31, 2005, the Portfolio reclassified $6,603 to accumulated net
realized loss from investments and $5,406,158 to net investment loss from paid
in capital to adjust for current period permanent book/tax differences which
arose principally from differing book/tax treatments of net operating losses and
security litigation. Net assets were not affected by these reclassifications.

NOTE 8. CONTINGENCIES

      In the normal course of business, the Portfolio may provide general
indemnifications pursuant to certain contracts and organizational documents. The
Portfolio's maximum exposure under these arrangements is dependent on future
claims that may be made against the Portfolio and, therefore, cannot be
estimated; however, based on experience, the risk of loss from such claims is
considered remote.

CREDIT SUISSE TRUST -- SMALL CAP GROWTH PORTFOLIO
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Board of Trustees of Credit Suisse Trust and Shareholders of Credit
Suisse Trust - Small Cap Growth Portfolio:

      In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Small Cap Growth Portfolio (the
"Portfolio"), a portfolio of the Credit Suisse Trust, at December 31, 2005, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended, and the financial highlights
for each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Portfolio's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements 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 are free of
material misstatement. An audit 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, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 2005 by
correspondence with the custodian, provide a reasonable basis for our opinion.

CREDIT SUISSE TRUST -- SMALL CAP GROWTH PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED)
- --------------------------------------------------------------------------------

      In approving the Advisory Agreement, the Board of Trustees, including the
Independent Trustees, considered the following factors with respect to the Small
Cap Growth Portfolio (the "Portfolio"):

      INVESTMENT ADVISORY FEE RATES

      The Board reviewed and considered the actual and contractual advisory fee
rate of 0.90% paid by the Portfolio ("Contractual Advisory Fee") to Credit
Suisse Asset Management LLC ("Credit Suisse") in light of the extent and quality
of the advisory services provided by Credit Suisse. Additionally, the Board
received and considered information comparing the Portfolio's Contractual
Advisory Fee and the Portfolio's overall expenses with those of funds in both
the relevant expense group ("Peer Group") and universe of funds (the "Universe")
provided by Lipper Inc., an independent provider of investment company data.

      NATURE, EXTENT AND QUALITY OF THE SERVICES UNDER THE ADVISORY AGREEMENTS

      The Board received and considered information regarding the nature, extent
and quality of services provided to the Portfolio by Credit Suisse under the
Advisory Agreement. The Board also noted information received at regular
meetings throughout the year related to the services rendered by Credit Suisse.
The Board reviewed background information about Credit Suisse, including its
Form ADV. The Board considered the background and experience of Credit Suisse's
senior management and the expertise of, and the amount of attention given to the
Portfolio by, senior personnel of Credit Suisse. In addition, the Board reviewed
the qualifications, backgrounds and responsibilities of the portfolio management
team primarily responsible for the day-to-day portfolio management of the
Portfolio and the extent of the resources devoted to research and analysis of
actual and potential investments. The Board also received and considered
information about the nature, extent and quality of services and fee rates
offered to other Credit Suisse clients for comparable services.

      PORTFOLIO PERFORMANCE

      The Board received and considered the one-, two-, three-, four-, five- and
ten-year performance of the Portfolio, along with comparisons, for all presented
periods, both to the relevant performance group ("Performance Group") and
universe of funds ("Performance Universe") for the Portfolio. The Board was
provided with a description of the methodology used to arrive at the funds
included in the Performance Group and the Performance Universe.

CREDIT SUISSE TRUST -- SMALL CAP GROWTH PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      The Board reviewed information comparing the performance of various Credit
Suisse Funds to performance benchmarks that the Board had previously established
and progress that had been made in certain instances toward achieving those
benchmarks. The Board also reviewed comparisons between the Portfolio and its
identified benchmark over various time periods.

      CREDIT SUISSE PROFITABILITY

      The Board received and considered a profitability analysis of Credit
Suisse based on the fees payable under the Advisory Agreement for the Portfolio,
including other relationships between the Portfolio on the one hand and Credit
Suisse affiliates on the other. The Board received profitability information for
the other funds in the Credit Suisse family of funds.

      ECONOMIES OF SCALE

      The Board considered whether economies of scale in the provision of
services to the Portfolio were being passed along to the shareholders.
Accordingly, the Board considered whether alternative fee structures (such as
breakpoint fee structures) would be more appropriate or reasonable taking into
consideration economies of scale or other efficiencies that might accrue from
increases in the Portfolio's asset levels.

      OTHER BENEFITS TO CREDIT SUISSE

      The Board considered other benefits received by Credit Suisse and its
affiliates as a result of their relationship with the Portfolio. Such benefits
include, among others, research arrangements with brokers who execute
transactions on behalf of the Portfolio, administrative and brokerage
relationships with affiliates of Credit Suisse and benefits potentially derived
from an increase in Credit Suisse's businesses as a result of its relationship
with the Portfolio (such as the ability to market to shareholders other
financial products offered by Credit Suisse and its affiliates).

      The Board considered the standards applied in seeking best execution,
whether and to what extent soft dollar credits are sought and how any such
credits are utilized, any benefits that may be achieved by using an affiliated
broker and the existence of quality controls applicable to brokerage allocation
procedures. The Board also reviewed Credit Suisse's method for allocating
portfolio investment opportunities among its advisory clients.

CREDIT SUISSE TRUST -- SMALL CAP GROWTH PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      CONCLUSIONS

      In selecting Credit Suisse, and approving the Advisory Agreement and the
investment advisory fee under such agreement, the Board concluded that:

      o     Although the Contractual Advisory Fee was higher than the median of
            the Portfolio's Peer Group, the fee was reasonable given the
            Portfolio's asset size.

      o     Over the review period, the Portfolio's performance did not exceed
            the third quintile of its Performance Group. The Portfolio's
            performance was above the median for the three- and four-year period
            in the Performance Universe and within or close to one standard
            deviation from the median for the one-, two-, five- and ten-year
            periods. The Board noted that it would continue to monitor steps
            undertaken by Credit Suisse to improve performance.

      o     Aside from performance (as described above), the Board was satisfied
            with the nature, extent and quality of the investment advisory
            services provided to the Portfolio by Credit Suisse and that, based
            on dialogue with management and counsel, the services provided by
            Credit Suisse under the Advisory Agreement are typical of, and
            consistent with, those provided to mutual funds by other investment
            advisers. The Board understood that Credit Suisse had addressed or
            was in the process of addressing any performance issues.

      o     In light of the costs of providing investment management and other
            services to the Portfolio and Credit Suisse's ongoing commitment to
            the Portfolio, the profits and other ancillary benefits that Credit
            Suisse and its affiliates received were considered reasonable.

      o     Credit Suisse's profitability based on fees payable under the
            Advisory Agreement was reasonable in light of the nature, extent and
            quality of the services provided to the Portfolio thereunder.

      o     In light of the relatively small size of the Portfolio, the
            Portfolio's current fee structure (without breakpoints) was
            considered reasonable.

      No single factor reviewed by the Board was identified by the Board as the
principal factor in determining whether to approve the Advisory Agreement. The
Independent Trustees were advised by separate independent legal counsel
throughout the process.

CREDIT SUISSE TRUST -- MID-CAP GROWTH PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

                                                                January 19, 2006

Dear Shareholder:

      For the 12 months ended December 31, 2005, Credit Suisse Trust--Mid-Cap
Growth Portfolio 1 (the "Portfolio") had a gain of 6.97%, vs. an increase of
12.10% for the Russell Midcap(R) Growth Index 2 and an increase of 8.18% for
the Russell 2500 TM Growth Index 3.

THE MARKET: POSITIVE DESPITE RISING ENERGY COSTS, INTEREST RATES

      The period was an overall positive one for equities. Stocks initially
struggled, but rallied into the summer, aided by benign inflation data and good
earnings reports from a number of visible companies. To be sure, headwinds were
ever-present, notably in the form of hurricane activity, surging energy prices
and a Federal Reserve that continued to raise short-term interest rates in small
but steady increments. In the face of all this, the economy nonetheless appeared
resilient, at least as of late 2005: Third-quarter GDP growth was reported at an
annualized rate of 4.1%, the tenth consecutive quarter of 3% or greater growth.
The earnings backdrop remained generally supportive late in the year.

      In the market, high energy prices helped drive the outperformance of
energy related stocks, which, despite some late-period weakness, outpaced all
other economic sectors in the period. This was reflected in the outperformance
of value stocks over growth stocks, as energy companies comprise a relatively
large share of the value universe. Mid-capitalization stocks generally
outperformed both large and small-cap stocks for the period.

STRATEGIC REVIEW: HEALTH CARE HOLDINGS COUNTER GOOD STOCK SELECTION ELSEWHERE

      The Portfolio participated in the market's rally but underperformed its
benchmarks, which we attribute primarily to stock selection in the health care
sector. Amerigroup, a managed care company, had a sizable decline in share price
as rising medical costs weighed on the company's earnings. We decided to
eliminate the position in the period. Another underperformer was Taro
Pharmaceuticals (1.3% of the Portfolio's net assets as of December 31, 2005), a
maker of prescription and over-the-counter drugs. The stock struggled amid
pressure on its earnings due to heightened competition. In addition, the
Portfolio's financial services holdings collectively underperformed.

CREDIT SUISSE TRUST -- MID-CAP GROWTH PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

      On the positive side, strong stock selection in the consumer discretionary
and consumer staples sectors aided the Portfolio's relative performance. The
Portfolio's producer durables holdings also outperformed, led by Crown Castle
International (1.3% of the Portfolio's net assets as of December 31, 2005),
which owns and operates wireless communication towers. The stock's appreciation
in 2005 reflected rising demand for the company's services. Also of note,
Macromedia, a Portfolio holding in the technology sector, was purchased by Adobe
(2.6% of the Portfolio's net assets as of December 31, 2005) late in the period,
and the stock was a solid performer in 2005 as a result. We opted to keep the
merged entity in the Portfolio. We believe the company has an attractively
expanded suite of products.

      Going forward, we will continue to seek to identify companies with
attractive capital-growth potential. Our stock-selection process emphasizes
companies we believe to have accelerating earnings, improving fundamentals,
competent management and compelling business models, including companies still
in their developmental stage as well as older companies that appear to be
entering a new stage of growth.

      RETURNS REPRESENT PAST PERFORMANCE AND INCLUDE CHANGE IN SHARE PRICE AND
REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS. PAST PERFORMANCE CANNOT GUARANTEE
FUTURE RESULTS. THE CURRENT PERFORMANCE OF THE PORTFOLIO MAY BE LOWER OR HIGHER
THAN THE FIGURES SHOWN. RETURNS AND SHARE PRICE WILL FLUCTUATE, AND REDEMPTION
VALUE MAY BE MORE OR LESS THAN ORIGINAL COST. THE PERFORMANCE RESULTS DO NOT
REFLECT THE DEDUCTION OF TAXES THAT A SHAREHOLDER WOULD PAY ON PORTFOLIO
DISTRIBUTIONS OR THE REDEMPTION OF PORTFOLIO SHARES. PERFORMANCE INCLUDES THE
EFFECT OF DEDUCTING EXPENSES, BUT DOES NOT INCLUDE CHARGES AND EXPENSES
ATTRIBUTABLE TO ANY PARTICULAR VARIABLE CONTRACT OR PLAN. ACCORDINGLY, THE
PROSPECTUS OF THE SPONSORING PARTICIPATING INSURANCE COMPANY SEPARATE ACCOUNT OR
PLAN DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS SHOULD
BE CAREFULLY REVIEWED FOR INFORMATION ON RELEVANT CHARGES AND EXPENSES.
EXCLUDING THESE CHARGES AND EXPENSES FROM QUOTATIONS OF PERFORMANCE HAS THE
EFFECT OF INCREASING THE PERFORMANCE QUOTED, AND THE EFFECT OF THESE CHARGES
SHOULD BE CONSIDERED WHEN COMPARING PERFORMANCE TO THAT OF OTHER MUTUAL FUNDS.

CREDIT SUISSE TRUST -- MID-CAP GROWTH PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

INFORMATION ABOUT YOUR PORTFOLIO'S EXPENSES

      As an investor of the Portfolio, you incur two types of costs: ongoing
expenses and transaction costs. Ongoing expenses include management fees,
distribution and service (12b-1) fees and other Portfolio expenses. Examples of
transaction costs include sales charges (loads), redemption fees and account
maintenance fees, which are not shown in this section and which would result in
higher total expenses. The following table is intended to help you understand
your ongoing expenses of investing in the Portfolio and to help you compare
these expenses with the ongoing expenses of investing in other mutual funds. The
table is based on an investment of $1,000 made at the beginning of the six month
period ended December 31, 2005.

      The table illustrates your Portfolio's expenses in two ways:

      o     ACTUAL PORTFOLIO RETURN. This helps you estimate the actual dollar
            amount of ongoing expenses paid on a $1,000 investment in the
            Portfolio using the Portfolio's actual return during the period. To
            estimate the expenses you paid over the period, simply divide your
            account value by $1,000 (for example, an $8,600 account value
            divided by $1,000 = 8.6), then multiply the result by the number in
            the "Expenses Paid per $1,000" line under the share class you hold.

      o     HYPOTHETICAL 5% PORTFOLIO RETURN. This helps you to compare your
            Portfolio's ongoing expenses with those of other mutual funds using
            the Portfolio's actual expense ratio and a hypothetical rate of
            return of 5% per year before expenses. Examples using a 5%
            hypothetical fund return may be found in the shareholder reports of
            other mutual funds. The hypothetical account values and expenses may
            not be used to estimate the actual ending account balance or
            expenses you paid for the period.

      Please note that the expenses shown in these tables are meant to highlight
your ongoing expenses only and do not reflect any transaction costs, such as
sales charges (loads) or redemption fees. If these transaction costs had been
included, your costs would have been higher. The "Expenses Paid per $1,000" line
of the tables is useful in comparing ongoing expenses only and will not help you
determine the relative total expenses of owning different funds.

ANNUALIZED EXPENSE RATIOS*                                                 1.25%

_____________
*     EXPENSES ARE EQUAL TO THE PORTFOLIO'S ANNUALIZED EXPENSE RATIO MULTIPLIED
      BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY THE NUMBER OF
      DAYS IN THE MOST RECENT FISCAL HALF YEAR PERIOD, THEN DIVIDED BY 365.

      THE "EXPENSES PAID PER $1,000" AND THE "ANNUALIZED EXPENSE RATIOS" IN THE
      TABLES ARE BASED ON ACTUAL EXPENSES PAID BY THE PORTFOLIO DURING THE
      PERIOD, NET OF FEE WAIVERS AND/OR EXPENSE REIMBURSEMENTS. IF THOSE FEE
      WAIVERS AND/OR EXPENSE REIMBURSEMENTS HAD NOT BEEN IN EFFECT, THE
      PORTFOLIO'S ACTUAL EXPENSES WOULD HAVE BEEN HIGHER. EXPENSES DO NOT
      REFLECT ADDITIONAL CHARGES AND EXPENSES THAT ARE, OR MAY BE, IMPOSED UNDER
      THE VARIABLE CONTRACTS OR PLANS. SUCH CHARGES AND EXPENSES ARE DESCRIBED
      IN THE PROSPECTUS OF THE INSURANCE COMPANY SEPARATE ACCOUNT OR IN THE PLAN
      DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS. THE
      PORTFOLIO'S EXPENSES SHOULD BE CONSIDERED WITH THESE CHARGES AND EXPENSES
      IN EVALUATING THE OVERALL COST OF INVESTING IN THE SEPARATE ACCOUNT.

For more information, please refer to the Portfolio's prospectus.

CREDIT SUISSE TRUST -- MID-CAP GROWTH PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
December 31, 2005
- --------------------------------------------------------------------------------

NOTE 1. ORGANIZATION

      Credit Suisse Trust (the "Trust") is an open-end management investment
company registered under the Investment Company Act of 1940, as amended, and
currently offers eight managed investment portfolios of which one, the Mid-Cap
Growth Portfolio, is included in this report. The Portfolio is a diversified
investment fund that seeks maximum capital appreciation. Shares of the Portfolio
are not available directly to individual investors but may be offered only
through (a) variable annuity contracts and variable life insurance contracts
offered by separate accounts of certain insurance companies and (b)
tax-qualified pension and retirement plans. The Portfolio may not be available
in connection with a particular contract or plan. The Trust was organized under
the laws of The Commonwealth of Massachusetts as a business trust on March 15,
1995.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      A) SECURITY VALUATION -- The net asset value of the Portfolio is
determined daily as of the close of regular trading on the New York Stock
Exchange, Inc. (the "Exchange") on each day the Exchange is open for business.
The Portfolio's equity investments are valued at market value, which is
generally determined using the closing price on the exchange or market on which
the security is primarily traded at the time of valuation (the "Valuation
Time"). If no sales are reported, equity investments are generally valued at the
most recent bid quotation as of the Valuation Time or at the lowest asked
quotation in the case of a short sale of securities. Debt securities with a
remaining maturity greater than 60 days are valued in accordance with the price
supplied by a pricing service, which may use a matrix, formula or other
objective method that takes into consideration market indices, yield curves and
other specific adjustments. Debt obligations that will mature in 60 days or less
are valued on the basis of amortized cost, which approximates market value,
unless it is determined that this method would not represent fair value.
Investments in mutual funds are valued at the mutual fund's closing net asset
value per share on the day of valuation. Securities and other assets for which
market quotations are not readily available, or whose values have been
materially affected by events occurring before the Portfolio's Valuation Time
but after the close of the securities' primary markets, are valued at fair value
as determined in good faith by, or under the direction of, the Board of Trustees
under procedures established by the Board of Trustees. The Portfolio may utilize
a service provided by an independent third party which has been

                                       16

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

approved by the Board of Trustees to fair value certain securities. When
fair-value pricing is employed, the prices of securities used by a portfolio to
calculate its net asset value may differ from quoted or published prices for the
same securities.

      B) SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions
are accounted for on a trade date basis. Interest income is recorded on the
accrual basis. Dividends are recorded on the ex-dividend date. The cost of
investments sold is determined by use of the specific identification method for
both financial reporting and income tax purposes.

      C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net
investment income and distributions of net realized capital gains, if any, are
declared and paid at least annually. However, to the extent that a net realized
capital gain can be reduced by a capital loss carryforward, such gain will not
be distributed. Income and capital gain distributions are determined in
accordance with federal income tax regulations, which may differ from accounting
principles generally accepted in the United States of America ("GAAP").

      D) FEDERAL INCOME TAXES -- No provision is made for federal taxes as it is
the Trust's intention to have the Portfolio continue to qualify for and elect
the tax treatment applicable to regulated investment companies under the
Internal Revenue Code of 1986, as amended, and to make the requisite
distributions to its shareholders, which will be sufficient to relieve it from
federal income and excise taxes.

      E) USE OF ESTIMATES -- The preparation of financial statements in
conformity with GAAP 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 revenues and expenses during the reporting period.
Actual results could differ from these estimates.

      F) SHORT-TERM INVESTMENTS -- The Portfolio, together with other
funds/portfolios advised by Credit Suisse Asset Management, LLC ("Credit
Suisse"), an indirect, wholly-owned subsidiary of Credit Suisse Group, pools
available cash into either a short-term variable rate time deposit issued by
State Street Bank and Trust Company ("SSB"), the Portfolio's custodian, or a

be secured by collateral at least equal to 102% of the market value of domestic
securities on loan (including any accrued interest thereon) and 105% of the
market value of foreign securities on loan (including any accrued interest
thereon). Cash collateral received by the Portfolio in connection with
securities lending activity may be pooled together with cash collateral for
other funds/portfolios advised by Credit Suisse and may be invested in a variety
of investments, including certain Credit Suisse-advised funds, funds advised by
SSB, the Portfolio's securities lending agent, or money market instruments.
However, in the event of default or bankruptcy by the other party to the
agreement, realization and/or retention of the collateral may be subject to
legal proceedings.

      SSB has been engaged by the Portfolio to act as the Portfolio's securities
lending agent. The Portfolio's securities lending arrangement provides that the
Portfolio and SSB will share the net income earned from the securities lending
activities. During the year ended December 31, 2005, total earnings from the
Portfolio's investment in cash collateral received in connection with securities
lending arrangements was $160,765, of which $154,246 was rebated to borrowers
(brokers). The Portfolio retained $4,581 in income from the cash collateral
investment, and SSB, as lending agent, was paid $1,938. The Portfolio may also
be entitled to certain minimum amounts of income from its securities lending
activities. Securities lending income is accrued as earned.

fractional shares of beneficial interest, $0.001 par value per share.
Transactions in capital shares of the Portfolio were as follows:

      On December 31, 2005, the number of shareholders that held 5% or more of
the outstanding shares of the Portfolio was as follows:

      Some of the shareholders are omnibus accounts, which hold shares on behalf
of individual shareholders.

NOTE 7. FEDERAL INCOME TAXES

      Income and capital gain distributions are determined in accordance with
federal income tax regulations, which may differ from GAAP.

      The tax basis of components of distributable earnings differ from the
amounts reflected in the Statement of Assets and Liabilities by temporary
book/tax differences. These differences are primarily due to losses deferred on
wash sales.

      At December 31, 2005, the components of distributable earnings on a tax
basis for the Portfolio were as follows:

         Accumulated net realized loss       $(12,884,952)
         Unrealized appreciation                6,040,709

NOTE 7. FEDERAL INCOME TAXES

      At December 31, 2005, the Portfolio had capital loss carryforwards
available to offset possible future capital gains as follows:

                              EXPIRES DECEMBER 31,
                         ------------------------------

                          $ 8,819,060      $ 4,065,892

      During the tax year ended December 31, 2005, the Portfolio utilized
$4,977,294 of the capital loss carryforward.

      At December 31, 2005, the identified cost for federal income tax purposes,
as well as the gross unrealized appreciation from investments for those
securities having an excess of value over cost, gross unrealized depreciation
from investments for those securities having an excess of cost over value and
the net unrealized appreciation from investments were as follows: $37,523,625,
$7,002,439, $(961,730) and $6,040,709, respectively.

      At December 31, 2005, the Portfolio reclassified $1,797 to accumulated net
realized loss from investments and $272,207 to net investment loss from paid-in
capital, to adjust for current period permanent book/tax differences which arose
principally from differing book/tax treatments of net operating losses and
dividends received from Real Estate Investment Trusts. Net assets were not
affected by these reclassifications.

NOTE 8. CONTINGENCIES

      In the normal course of business, the Portfolio may provide general
indemnifications pursuant to certain contracts and organizational documents. The
Portfolio's maximum exposure under these arrangements is dependent on future
claims that may be made against the Portfolio and, therefore, cannot be
estimated; however, based on experience, the risk of loss from such claims is
considered remote.

CREDIT SUISSE TRUST -- MID-CAP GROWTH PORTFOLIO
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Board of Trustees of Credit Suisse Trust and Shareholders of Credit
Suisse Trust - Mid-Cap Growth Portfolio:

      In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Mid-Cap Growth Portfolio (the
"Portfolio"), a portfolio of the Credit Suisse Trust, at December 31, 2005, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended and the financial highlights
for each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Portfolio's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements 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 are free of
material misstatement. An audit 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, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 2005 by
correspondence with the custodian, provide a reasonable basis for our opinion.

CREDIT SUISSE TRUST -- MID-CAP GROWTH PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED)
- --------------------------------------------------------------------------------

      In approving the Advisory Agreement, the Board of Trustees, including the
Independent Trustees, considered the following factors with respect to the
Mid-Cap Growth Portfolio (the "Portfolio"):

      INVESTMENT ADVISORY FEE RATES

      The Board reviewed and considered the contractual advisory fee rate of
0.90% paid by the Portfolio ("Contractual Advisory Fee") to Credit Suisse Asset
Management LLC ("Credit Suisse") in light of the extent and quality of the
advisory services provided by Credit Suisse. The Board also reviewed and
considered the fee waivers and/or expense reimbursement arrangements currently
in place for the Portfolio and considered the actual fee rates of 0.82% paid by
the Portfolio ("Net Advisory Fee") after taking waivers and reimbursements into
account. The Board acknowledged that the fee waivers and reimbursements could be
discontinued at any time.

      Additionally, the Board received and considered information comparing the
Portfolio's Contractual Advisory Fee and Net Advisory Fee and the Portfolio's
overall expenses with those of funds in both the relevant expense group ("Peer
Group") and universe of funds (the "Universe") provided by Lipper Inc., an
independent provider of investment company data.

      NATURE, EXTENT AND QUALITY OF THE SERVICES UNDER THE ADVISORY AGREEMENT

      The Board received and considered information regarding the nature, extent
and quality of services provided to the Portfolio by Credit Suisse under the
Advisory Agreement. The Board also noted information received at regular
meetings throughout the year related to the services rendered by Credit Suisse.
The Board reviewed background information about Credit Suisse, including its
Form ADV. The Board considered the background and experience of Credit Suisse's
senior management and the expertise of, and the amount of attention given to the
Portfolio by, senior personnel of Credit Suisse. In addition, the Board reviewed
the qualifications, backgrounds and responsibilities of the portfolio management
team primarily responsible for the day-to-day portfolio management of the
Portfolio and the extent of the resources devoted to research and analysis of
actual and potential investments. The Board also received and considered
information about the nature, extent and quality of services and fee rates
offered to other Credit Suisse clients for comparable services.

CREDIT SUISSE TRUST -- MID-CAP GROWTH PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      PORTFOLIO PERFORMANCE

      The Board received and considered the one-, two-, three-, four- and
five-year performance of the Portfolio, along with comparisons, for all
presented periods, both to the relevant performance group ("Performance Group")
and universe of funds ("Performance Universe") for the Portfolio. The Board was
provided with a description of the methodology used to arrive at the funds
included in the Performance Group and the Performance Universe.

      The Board reviewed information comparing the performance of various Credit
Suisse Funds to performance benchmarks that the Board had previously established
and progress that had been made in certain instances toward achieving those
benchmarks. The Board also reviewed comparisons between the Portfolio and its
identified benchmark over various time periods.

      CREDIT SUISSE PROFITABILITY

      The Board received and considered a profitability analysis of Credit
Suisse based on the fees payable under the Advisory Agreement for the Portfolio,
including any fee waivers or fee caps, as well as other relationships between
the Portfolio on the one hand and Credit Suisse affiliates on the other. The
Board received profitability information for the other funds in the Credit
Suisse family of funds.

      ECONOMIES OF SCALE

      The Board considered whether economies of scale in the provision of
services to the Portfolio were being passed along to the shareholders.
Accordingly, the Board considered whether alternative fee structures (such as
breakpoint fee structures) would be more appropriate or reasonable taking into
consideration economies of scale or other efficiencies that might accrue from
increases in the Portfolio's asset levels.

      OTHER BENEFITS TO CREDIT SUISSE

      The Board considered other benefits received by Credit Suisse and its
affiliates as a result of their relationship with the Portfolio. Such benefits
include, among others, research arrangements with brokers who execute
transactions on behalf of the Portfolio, administrative and brokerage
relationships with affiliates of Credit Suisse and benefits potentially derived
from an increase in Credit Suisse's businesses as a result of its relationship
with the Portfolio (such as the ability to market to shareholders other
financial products offered by Credit Suisse and its affiliates).

CREDIT SUISSE TRUST -- MID-CAP GROWTH PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      The Board considered the standards applied in seeking best execution,
whether and to what extent soft dollar credits are sought and how any such
credits are utilized, any benefits that may be achieved by using an affiliated
broker and the existence of quality controls applicable to brokerage allocation
procedures. The Board also reviewed Credit Suisse's method for allocating
portfolio investment opportunities among its advisory clients.

      CONCLUSIONS

      In selecting Credit Suisse, and approving the Advisory Agreement and the
investment advisory fee under such agreement, the Board concluded that:

      o     Although the Contractual Advisory Fee was above the median of the
            Portfolio's Expense Group, the Net Advisory Fee was slightly below
            the median of the Portfolio's Expense Group and would be reduced
            further to 0.77% when the additional voluntary fee waiver (described
            below) is taken into account. The Board considered the fee to be
            reasonable taking into account the fee waiver and the Portfolio's
            relatively small size.

      o     The Portfolio's one-, two- three-, four- and five-year performance
            was higher than the median of the Portfolio's Performance Group,
            Performance Universe and benchmark, except that the Portfolio's
            two-year performance was equal to the median for the Performance
            Universe. The Board had previously identified the need to address
            the Portfolio's performance, and noted that Credit Suisse was in the
            process of addressing performance issues. After discussion with the
            Board, Credit Suisse had agreed to an additional one-year voluntary
            fee waiver of five basis points. The Board would continue to monitor
            steps undertaken by Credit Suisse to improve performance.

      o     The Board was satisfied with the nature and extent of the investment
            advisory services provided to the Portfolio by Credit Suisse, and
            that, based on dialogue with management and counsel, the services
            provided by Credit Suisse under the Advisory Agreement are typical
            of, and consistent with, those provided to mutual funds by other
            investment advisers. The Board understood that Credit Suisse was in
            the process of addressing any performance issues.

      o     In light of the costs of providing investment management and other
            services to the Portfolio and Credit Suisse's ongoing commitment to
            the Portfolio and willingness to cap fees and expenses, the profits
            and other ancillary benefits that Credit Suisse and its affiliates
            received were considered reasonable.

                                       25




CREDIT SUISSE TRUST -- MID-CAP GROWTH PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      o     Credit Suisse's profitability based on fees payable under the
            Advisory Agreement was reasonable in light of the nature, extent and
            quality of the services provided to the Portfolio thereunder.

      o     In light of the relatively small size of the Portfolio, the amount
            of the Net Advisory Fees and the additional voluntary fee reduction,
            the Portfolio's current fee structure (without breakpoints) was
            considered reasonable.

      No single factor reviewed by the Board was identified by the Board as the
principal factor in determining whether to approve the Advisory Agreement. The
Independent Trustees were advised by separate independent legal counsel
throughout the process.

CREDIT SUISSE TRUST -- LARGE CAP VALUE PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

                                                                January 26, 2006


Dear Shareholder:

      For the 12 months ended December 31, 2005, Credit Suisse Trust-Large Cap
Value Portfolio 1 (the "Portfolio") had a gain of 8.14%, vs. an increase of
7.05% for the Russell 1000(R) Value Index. 2

THE MARKET: POSITIVE DESPITE RISING ENERGY COSTS, INTEREST RATES

      The period was an overall positive one for equities. Stocks initially
struggled, but rallied into the summer, aided by benign inflation data and good
earnings reports from a number of visible companies. To be sure, headwinds were
ever-present, notably in the form of hurricane activity, surging energy prices
and a Federal Reserve that continued to raise short-term interest rates in small
but steady increments. In the face of all this, the economy nonetheless appeared
resilient, at least as of late 2005: Third-quarter GDP growth was reported at an
annualized rate of 4.1%, the tenth consecutive quarter of 3% or greater growth.
The earnings backdrop remained generally supportive late in the year.

      In the market, high energy prices helped drive the outperformance of
energy related stocks, which, despite some late-period weakness, outpaced all
other economic sectors in the period. This was reflected in the outperformance
of value stocks over growth stocks, as energy companies comprise a relatively
large portion of the value universe. Mid-capitalization stocks generally
outperformed both large- and small-cap stocks for the period.

STRATEGIC REVIEW: CONSUMER AND ENERGY HOLDINGS DRIVE OUTPERFORMANCE

      The Portfolio outperformed its benchmark in the period, aided by good
stock selection in the consumer sector, in particular retailers and providers of
consumer staples products. The Portfolio's performance also reflected favorable
stock selection in the energy, utilities and transportation areas. On the
negative side, the Portfolio's materials and technology holdings struggled.

      With regard to noteworthy recent portfolio activity, our purchases
included Chevron (3.2% of the Portfolio's net assets as of December 31, 2005), a
major integrated oil company that we believe could benefit from a recent
acquisition, in part due to expanded exploration opportunities. We also
established a position in AT&T (1.5% of the Portfolio's net assets as of
December 31, 2005).

CREDIT SUISSE TRUST -- LARGE CAP VALUE PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

The stock was attractively valued in our view, and offered a relatively high
dividend yield. Our sales included the elimination of Burlington Resources, an
energy exploration and production company focused primarily on natural gas. The
stock had a sharp upward spike late in the period and it reached our valuation
target.

      Going forward, we will continue to adhere to our general strategy of
investing in dividend-paying stocks of companies with large market
capitalizations. Using proprietary bottom-up equity research and detailed
quantitative analyses, we look for stocks that are deeply discounted relative to
our view of their upside potential, in terms of valuation and/or income, with an
emphasis on companies that stand to benefit from the positive impact of a likely
significant event.

      RETURNS REPRESENT PAST PERFORMANCE AND INCLUDE CHANGES IN SHARE PRICE AND
REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS. PAST PERFORMANCE CANNOT GUARANTEE
FUTURE RESULTS. THE CURRENT PERFORMANCE OF THE PORTFOLIO MAY BE LOWER OR HIGHER
THAN THE FIGURES SHOWN. RETURNS AND SHARE PRICE WILL FLUCTUATE, AND REDEMPTION
VALUE MAY BE MORE OR LESS THAN ORIGINAL COST. THE PERFORMANCE RESULTS DO NOT
REFLECT THE DEDUCTION OF TAXES THAT A SHAREHOLDER WOULD PAY ON PORTFOLIO
DISTRIBUTIONS OR THE REDEMPTION OF PORTFOLIO SHARES. PERFORMANCE INCLUDES THE
EFFECT OF DEDUCTING EXPENSES, BUT DOES NOT INCLUDE CHARGES AND EXPENSES
ATTRIBUTABLE TO ANY PARTICULAR VARIABLE CONTRACT OR PLAN. ACCORDINGLY, THE
PROSPECTUS OF THE SPONSORING PARTICIPATING INSURANCE COMPANY SEPARATE ACCOUNT OR
PLAN DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS SHOULD
BE CAREFULLY REVIEWED FOR INFORMATION ON RELEVANT CHARGES AND EXPENSES.
EXCLUDING THESE CHARGES AND EXPENSES FROM QUOTATIONS OF PERFORMANCE HAS THE
EFFECT OF INCREASING THE PERFORMANCE QUOTED, AND THE EFFECT OF THESE CHARGES
SHOULD BE CONSIDERED WHEN COMPARING PERFORMANCE TO THAT OF OTHER MUTUAL FUNDS.

ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
December 31, 2005 (unaudited)

INFORMATION ABOUT YOUR PORTFOLIO'S EXPENSES

      As an investor of the Portfolio, you incur two types of costs: ongoing
expenses and transaction costs. Ongoing expenses include management fees,
distribution and service (12b-1) fees and other Portfolio expenses. Examples of
transaction costs include sales charges (loads), redemption fees and account
maintenance fees, which are not shown in this section and which would result in
higher total expenses. The following table is intended to help you understand
your ongoing expenses of investing in the Portfolio and to help you compare
these expenses with the ongoing expenses of investing in other mutual funds. The
table is based on an investment of $1,000 made at the beginning of the six month
period ended December 31, 2005.

      The table illustrates your Portfolio's expenses in two ways:

      o     ACTUAL PORTFOLIO RETURN. This helps you estimate the actual dollar
            amount of ongoing expenses paid on a $1,000 investment in the
            Portfolio using the Portfolio's actual return during the period. To
            estimate the expenses you paid over the period, simply divide your
            account value by $1,000 (for example, an $8,600 account value
            divided by $1,000 = 8.6), then multiply the result by the number in
            the "Expenses Paid per $1,000" line under the share class you hold.

      o     HYPOTHETICAL 5% PORTFOLIO RETURN. This helps you to compare your
            Portfolio's ongoing expenses with those of other mutual funds using
            the Portfolio's actual expense ratio and a hypothetical rate of
            return of 5% per year before expenses. Examples using a 5%
            hypothetical fund return may be found in the shareholder reports of
            other mutual funds. The hypothetical account values and expenses may
            not be used to estimate the actual ending account balance or
            expenses you paid for the period.

      Please note that the expenses shown in these tables are meant to highlight
your ongoing expenses only and do not reflect any transaction costs, such as
sales charges (loads) or redemption fees. If these transaction costs had been
included, your costs would have been higher. The "Expenses Paid per $1,000" line
of the tables is useful in comparing ongoing expenses only and will not help you
determine the relative total expenses of owning different funds.

      PERIOD, NET OF FEE WAIVERS AND/OR EXPENSE REIMBURSEMENTS. IF THOSE FEE
      WAIVERS AND/OR EXPENSE REIMBURSEMENTS HAD NOT BEEN IN EFFECT, THE

      REFLECT ADDITIONAL CHARGES AND EXPENSES THAT ARE, OR MAY BE, IMPOSED UNDER
      THE VARIABLE CONTRACTS OR PLANS. SUCH CHARGES AND EXPENSES ARE DESCRIBED
      IN THE PROSPECTUS OF THE INSURANCE COMPANY SEPARATE ACCOUNT OR IN THE PLAN
      DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS. THE
      PORTFOLIO'S EXPENSES SHOULD BE CONSIDERED WITH THESE CHARGES AND EXPENSES
      IN EVALUATING THE OVERALL COST OF INVESTING IN THE SEPARATE ACCOUNT.

CREDIT SUISSE TRUST -- LARGE CAP VALUE PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
December 31, 2005
- --------------------------------------------------------------------------------

NOTE 1. ORGANIZATION

      Credit Suisse Trust (the "Trust") is an open-end management investment
company registered under the Investment Company Act of 1940, as amended, and
currently offers eight managed investment portfolios of which one, the Large Cap
Value Portfolio (the "Portfolio"), is included in this report. The Portfolio is
a diversified investment fund that seeks long-term growth of capital and income.
Shares of the Portfolio are not available directly to individual investors but
may be offered only through (a) variable annuity contracts and variable life
insurance contracts offered by separate accounts of certain insurance companies
and (b) tax-qualified pension and retirement plans. The Portfolio may not be
available in connection with a particular contract or plan. The Trust was
organized under the laws of The Commonwealth of Massachusetts as a business
trust on March 15, 1995.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      A) SECURITY VALUATION -- The net asset value of the Portfolio is
determined daily as of the close of regular trading on the New York Stock
Exchange, Inc. (the "Exchange") on each day the Exchange is open for business.
The Portfolio's equity investments are valued at market value, which is
generally determined using the closing price on the exchange or market on which
the security is primarily traded at the time of valuation (the "Valuation
Time"). If no sales are reported, equity investments are generally valued at the
most recent bid quotation as of the Valuation Time or at the lowest asked
quotation in the case of a short sale of securities. Debt securities with a
remaining maturity greater than 60 days are valued in accordance with the price
supplied by a pricing service, which may use a matrix, formula or other
objective method that takes into consideration market indices, yield curves and
other specific adjustments. Debt obligations that will mature in 60 days or less
are valued on the basis of amortized cost, which approximates market value,
unless it is determined that using this method would not represent fair value.
Investments in mutual funds are valued at the mutual fund's closing net asset
value per share on the day of valuation. Securities and other assets for which
market quotations are not readily available, or whose values have been
materially affected by events occurring before the Portfolio's Valuation Time
but after the close of the securities' primary markets, are valued at fair value
as determined in good faith by, or under the direction of, the Board of Trustees
under procedures established by the Board of Trustees. The Portfolio may utilize
a service provided by an independent

                                       16




CREDIT SUISSE TRUST -- LARGE CAP VALUE PORTFOLIO
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

- --------------------------------------------------------------------------------

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

third party which has been approved by the Board of Trustees to fair value
certain securities. When fair-value pricing is employed, the price of securities
used by the fund to calculate its net asset value may differ from quoted or
published prices for the same securities.

      B) FOREIGN CURRENCY TRANSACTIONS -- The books and records of the Portfolio
are maintained in U.S. dollars. Transactions denominated in foreign currencies
are recorded at the current prevailing exchange rates. All assets and
liabilities denominated in foreign currencies are translated into U.S. dollar
amounts at the current exchange rate at the end of the period. Translation gains
or losses resulting from changes in the exchange rate during the reporting
period and realized gains and losses on the settlement of foreign currency
transactions are reported in the results of operations for the current period.
The Portfolio does not isolate that portion of realized gains and losses on
investments in EQUITY securities which is due to changes in the foreign exchange
rate from that which is due to changes in market prices of equity securities.
The Portfolio isolates that portion of realized gains and losses on investments
in DEBT securities which is due to changes in the foreign exchange rate from
that which is due to changes in market prices of debt securities.

      C) SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions
are accounted for on a trade date basis. Interest income is recorded on the
accrual basis. Dividends are recorded on the ex-dividend date. The cost of
investments sold is determined by use of the specific identification method for
both financial reporting and income tax purposes.

      D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net
investment income and distributions of net realized capital gains, if any, are
declared and paid at least annually. However, to the extent that a net realized
capital gain can be reduced by a capital loss carryforward, such gain will not
be distributed. Income and capital gain distributions are determined in
accordance with federal income tax regulations, which may differ from accounting
principles generally accepted in the United States of America ("GAAP").

      E) FEDERAL INCOME TAXES -- No provision is made for federal taxes as it is
the Trust's intention to have the Portfolio continue to qualify for and elect
the tax treatment applicable to regulated investment companies under the
Internal Revenue Code of 1986, as amended, and to make the requisite

                                       17

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

distributions to its shareholders, which will be sufficient to relieve it from
federal income and excise taxes.

      F) USE OF ESTIMATES -- The preparation of financial statements in
conformity with GAAP requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent asset and liabilities at the date of the financial statements and the
reported amounts of revenues and expenses during the reporting year. Actual
results could differ from these estimates.

      G) SHORT-TERM INVESTMENTS -- The Portfolio, together with other
funds/portfolios advised by Credit Suisse Asset Management, LLC ("Credit
Suisse"), an indirect, wholly-owned subsidiary of Credit Suisse Group, pools
available cash into either a short-term variable rate time deposit issued by
State Street Bank and Trust Company ("SSB"), the Portfolio's custodian, or a
money market fund advised by Credit Suisse. The short-term time deposit issued
by SSB is a variable rate account classified as a short-term investment.

      H) SECURITIES LENDING -- Loans of securities are required at all times to
be secured by collateral at least equal to 102% of the market value of domestic
securities on loan (including any accrued interest thereon) and 105% of the
market value of foreign securities on loan (including any accrued interest
thereon). Cash collateral received by the Portfolio in connection with
securities lending activity may be pooled together with cash collateral for
other funds/portfolios advised by Credit Suisse and may be invested in a variety
of investments, including certain Credit Suisse-advised funds, funds advised by
SSB, the Portfolio's securities lending agent, or money market instruments.
However, in the event of default or bankruptcy by the other party to the
agreement, realization and/or retention of the collateral may be subject to
legal proceedings.

      SSB has been engaged by the Portfolio to act as the Portfolio's securities
lending agent. The Portfolio's securities lending arrangement provides that the
Portfolio and SSB will share the net income earned from securities lending
activities. During the year ended December 31, 2005, total earnings from the
Portfolio's investment in cash collateral received in connection with securities
lending arrangements was $31,089 of which $26,111 was rebated to borrowers
(brokers). The Portfolio retained $3,490 in income from the cash collateral
investment, and SSB, as lending agent, was paid $1,488. The Portfolio may also

be entitled to certain minimum amounts of income from its securities lending
activities. Securities lending income is accrued as earned.

NOTE 3. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

      Credit Suisse serves as investment adviser for the Portfolio. For its
investment advisory services, Credit Suisse is entitled to receive a fee from
the Portfolio at an annual rate of 0.75% of the Portfolio's average daily net
assets. For the year ended December 31, 2005, investment advisory fees earned
and voluntarily waived were $408,312 and $50,255 respectively. Credit Suisse
will not recapture from the Portfolio any fees it waived during the fiscal year
ended December 31, 2005. Fee waivers and reimbursements are voluntary and may be
discontinued by Credit Suisse at any time.

      Credit Suisse Asset Management Securities, Inc. ("CSAMSI"), an affiliate
of Credit Suisse, and SSB serve as co-administrators to the Portfolio.

      For its co-administrative services, CSAMSI currently receives a fee
calculated at an annual rate of 0.10% of the average daily net assets of the
Portfolio. For the year ended December 31, 2005, co-administrative services fees
earned by CSAMSI were $54,442.

      For its co-administrative services, SSB receives a fee, exclusive of
out-of-pocket expenses, calculated in total for all the Credit Suisse
funds/portfolios co-administered by SSB and allocated based upon relative
average net assets of each fund/portfolio, subject to an annual minimum fee. For
the year ended December 31, 2005, co-administrative services fees earned by SSB
(including out-of-pocket expenses) were $49,055.

      In addition to serving as the Portfolio's co-administrator, CSAMSI
currently serves as distributor of the Portfolio's shares without compensation.

      Merrill Corporation ("Merrill"), an affiliate of Credit Suisse, has been
engaged by the Portfolio to provide certain financial printing and fulfillment
services. For the year ended December 31, 2005, Merrill was paid $4,184 for its
services to the Portfolio.

NOTE 4. LINE OF CREDIT

      The Portfolio, together with other funds/portfolios advised by Credit
Suisse (collectively, the "Participating Funds"), participates in a $75 million
committed, unsecured line of credit facility ("Credit Facility") for temporary

emergency purposes with Deutsche Bank, A.G. as administrative agent and
syndication agent and SSB as operations agent. Under the terms of the Credit
Facility, the Participating Funds pay an aggregate commitment fee at a rate of
0.10% per annum on the average unused amount of the Credit Facility, which is
allocated among the Participating Funds in such manner as is determined by the
governing Boards of the Participating Funds. In addition, the Participating
Funds pay interest on borrowings at the Federal Funds rate plus 0.50%. At

NOTE 7. FEDERAL INCOME TAXES

      Income and capital gain distributions are determined in accordance with
federal income tax regulations, which may differ from GAAP.

      The tax characteristics of dividends paid during the year ended December
31, 2005 and 2004, respectively, for the Portfolio were as follows:

                                  ORDINARY INCOME
                               --------------------
                                 2005        2004
                               --------    --------
                               $473,434    $221,475

      The tax basis of components of distributable earnings differ from the
amounts reflected in the Statement of Assets and Liabilities by temporary
book/tax differences. These differences are primarily due to losses deferred on
wash sales and deferral of post-October losses.

      At December 31, 2005, the components of distributable earnings on a tax
basis for the Portfolio were as follows:

      Undistributed net investment income               $  560,486
      Accumulated net realized loss                       (159,564)
      Unrealized appreciation                            7,396,648
      Deferral of post-October currency losses                (888)
                                                        ----------

                                                        $7,796,682
                                                        ==========

      At December 31, 2005, the Portfolio had capital loss carryforwards
available to offset possible future capital gains as follows:

                              EXPIRES DECEMBER 31,
                              --------------------
                                      2012
                                    --------
                                    $159,564

      Under current tax law, certain capital losses realized after October 31
within a taxable year may be deferred and treated as occuring on the first day
of the following tax year. For the tax period ended December 31, 2005, the
Portfolio elected to defer net losses arising between November 1, 2005 and
December 31, 2005 of $888.

      During the tax year ended December 31, 2005, the Portfolio utilized
$4,016,886 of the capital loss carryforward.

      At December 31, 2005, the identified cost for federal income tax purposes,
as well as the gross unrealized appreciation from investments for those
securities having an excess of value over cost, gross unrealized depreciation
from investments for those securities having an excess of cost over value and
the net unrealized appreciation from investments were as follows: $52,104,891,
$7,979,751, $(583,083) and $7,396,668, respectively.

NOTE 7. FEDERAL INCOME TAXES

      At December 31, 2005, the Portfolio reclassified $66 to undistributed net
investment income from accumulated net realized loss, to adjust for current
period permanent book/tax treatments on foreign currency transactions. Net
assets were not affected by these reclassifications.

NOTE 8. CONTINGENCIES

      In the normal course of business, the Portfolio may provide general
indemnifications pursuant to certain contracts and organizational documents. The
Portfolio's maximum exposure under these arrangements is dependent on future
claims that may be made against the Portfolio and, therefore, cannot be
estimated; however, based on experience, the risk of loss from such claims is
considered remote.

CREDIT SUISSE TRUST -- LARGE CAP VALUE PORTFOLIO
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Board of Trustees of Credit Suisse Trust and Shareholders of Credit
Suisse Trust - Large Cap Value Portfolio:

      In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Large Cap Value Portfolio (the
"Portfolio"), a portfolio of the Credit Suisse Trust, at December 31, 2005, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended and the financial highlights
for each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Portfolio's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements 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 are free of
material misstatement. An audit 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, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 2005 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

CREDIT SUISSE TRUST -- LARGE CAP VALUE PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED)
- --------------------------------------------------------------------------------

      In approving the Advisory Agreement, the Board of Trustees, including the
Independent Trustees, considered the following factors with respect to the Large
Cap Value Portfolio (the "Portfolio"):

      INVESTMENT ADVISORY FEE RATES

      The Board reviewed and considered the contractual advisory fee rate of
0.75% for the Portfolio ("Contractual Advisory Fee") in light of the extent and
quality of the advisory services provided by Credit Suisse Asset Management LLC
("Credit Suise"). The Board also reviewed and considered the fee waivers and/or
expense reimbursement arrangements currently in place for the Portfolio and
considered the actual fee rates after taking waivers and reimbursements into
account of 0.61% paid by the Portfolio ("Net Advisory Fee"). The Board
acknowledged that the fee waivers and reimbursements could be discontinued at
any time.

      Additionally, the Board received and considered information comparing the
Portfolio's Contractual Advisory Fee and Net Advisory Fee and the Portfolio's
overall expenses with those of funds in both the relevant expense group ("Peer
Group") and universe of funds (the "Universe") provided by Lipper Inc., an
independent provider of investment company data.

      NATURE, EXTENT AND QUALITY OF THE SERVICES UNDER THE ADVISORY AGREEMENT

      The Board received and considered information regarding the nature, extent
and quality of services provided to the Portfolio by Credit Suisse under the
Advisory Agreement. The Board also noted information received at regular
meetings throughout the year related to the services rendered by Credit Suisse.
The Board reviewed background information about Credit Suisse, including its
Form ADV. The Board considered the background and experience of Credit Suisse's
senior management and the expertise of, and the amount of attention given to the
Portfolio by, senior personnel of Credit Suisse. In addition, the Board reviewed
the qualifications, backgrounds and responsibilities of the portfolio management
team primarily responsible for the day-to-day portfolio management of the
Portfolio and the extent of the resources devoted to research and analysis of
actual and potential investments. The Board also received and considered
information about the nature, extent and quality of services and fee rates
offered to other Credit Suisse clients for comparable services.

      PORTFOLIO PERFORMANCE

      The Board received and considered the one-, two-, three-, four- and
five-year performance of the Portfolio, along with comparisons, for all
presented periods, both to the relevant performance group ("Performance Group")
and universe

                                       24

- --------------------------------------------------------------------------------

of funds ("Performance Universe") for the Portfolio. The Board was provided with
a description of the methodology used to arrive at the funds included in the
Performance Group and the Performance Universe.

      The Board reviewed information comparing the performance of various Credit
Suisse Funds to performance benchmarks that the Board had previously established
and progress that had been made in certain instances toward achieving those
benchmarks. The Board also reviewed comparisons between the Portfolio and its
identified benchmark over various time periods.

      CREDIT SUISSE PROFITABILITY

      The Board received and considered a profitability analysis of Credit
Suisse based on the fees payable under the Advisory Agreement for the Portfolio,
including any fee waivers or fee caps, as well as other relationships between
the Portfolio on the one hand and Credit Suisse affiliates on the other. The
Board received profitability information for the other funds in the Credit
Suisse family of funds.

      ECONOMIES OF SCALE

      The Board considered whether economies of scale in the provision of
services to the Portfolio were being passed along to the shareholders.
Accordingly, the Board considered whether alternative fee structures (such as
breakpoint fee structures) would be more appropriate or reasonable taking into
consideration economies of scale or other efficiencies that might accrue from
increases in the Portfolio's asset levels.

      OTHER BENEFITS TO CREDIT SUISSE

      The Board considered other benefits received by Credit Suisse and its
affiliates as a result of their relationship with the Portfolio. Such benefits
include, among others, research arrangements with brokers who execute
transactions on behalf of the Portfolio, administrative and brokerage
relationships with affiliates of Credit Suisse and benefits potentially derived
from an increase in Credit Suisse's businesses as a result of its relationship
with the Portfolio (such as the ability to market to shareholders other
financial products offered by Credit Suisse and its affiliates).

      The Board considered the standards applied in seeking best execution,
whether and to what extent soft dollar credits are sought and how any such
credits are utilized, any benefits that may be achieved by using an affiliated
broker and the existence of quality controls applicable to brokerage allocation

                                       25

procedures. The Board also reviewed Credit Suisse's method for allocating
portfolio investment opportunities among its advisory clients.

      CONCLUSIONS

      In selecting Credit Suisse, and approving the Advisory Agreement and the
investment advisory fee under such agreement, the Board concluded that:

      o     Although the Contractual Advisory Fee was higher than that of the
            Portfolio's Peer Group, the Net Advisory Fee was below the median of
            the Portfolio's Peer Group. In addition, the Board recognized that
            Credit Suisse has historically evidenced a willingness to waive
            fees. In light of the Portfolio's relatively small size, the fee was
            considered reasonable.

      o     The Portfolio's one- and two-year performance was in the third and
            second quintile, respectively, for its Performance Group and in the
            second quintile for both periods in its Performance Universe. The
            Portfolio's three-, four- and five-year performance was below the
            median for its Performance Universe, although the Portfolio's five
            year performance was in the second quintile for its Performance
            Group. The Board noted that the Portfolio's performance for the
            periods under review was above or within a reasonable range, one
            standard deviation, of the median for its Performance Group. The
            Board noted the Portfolio's performance was improving in absolute
            terms and that Credit Suisse was in the process of addressing
            performance issues.

      o     Aside from performance (as described above), the Board was satisfied
            with the nature and extent of the investment advisory services
            provided to the Portfolio by Credit Suisse, and that based on
            dialogue with management and counsel, the services provided by
            Credit Suisse under the Advisory Agreement are typical of, and
            consistent with, those provided to mutual funds by other investment
            advisers. The Board understood that Credit Suisse had or was in the
            process of addressing any performance issues.

      o     In light of the costs of providing investment management and other
            services to the Portfolio and Credit Suisse's ongoing commitment to
            the Portfolio and willingness to cap fees and expenses, the profits
            and other ancillary benefits that Credit Suisse and its affiliates
            received were considered reasonable.

      o     Credit Suisse's profitability based on fees payable under the
            Advisory Agreement was reasonable in light of the nature, extent and
            quality of the services provided to the Portfolio thereunder.

                                       26




CREDIT SUISSE TRUST -- LARGE CAP VALUE PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      o     In light of the relatively small size of the Portfolio and the
            amount of the Net Advisory Fees, the Portfolio's current fee
            structure (without breakpoints) was considered reasonable.

      No single factor reviewed by the Board was identified by the Board as the
principal factor in determining whether to approve the Advisory Agreement. The
Independent Trustees were advised by separate independent legal counsel
throughout the process.

CREDIT SUISSE TRUST -- SMALL CAP VALUE PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

                                                                January 26, 2006

Dear Shareholder:

      For the 12 months ended December 31, 2005, Credit Suisse Trust--Small Cap
Value Portfolio 1 (the "Portfolio") had a gain of 7.67%, vs. an increase of
4.55% for the Russell 2000(R) Index 2 and an increase of 4.71% for the Russell
2000(R) Value Index. 3

THE MARKET: POSITIVE DESPITE RISING ENERGY COSTS, INTEREST RATES

      The period was an overall positive one for equities. Stocks initially
struggled, but rallied into the summer, aided by benign inflation data and good
earnings reports from a number of visible companies. To be sure, headwinds were
ever-present, notably in the form of hurricane activity, surging energy prices
and a Federal Reserve that continued to raise short-term interest rates in small
but steady increments. In the face of all this, the economy nonetheless appeared
resilient, at least as of late 2005: Third-quarter GDP growth was reported at an
annualized rate of 4.1%, the tenth consecutive quarter of 3% or greater growth.
The earnings backdrop remained generally supportive late in the year.

      In the market, high energy prices helped drive the outperformance of
energy related stocks, which, despite some late-period weakness, outpaced all
other economic sectors in the period. This was reflected in the outperformance
of value stocks over growth stocks, as energy companies comprise a relatively
large portion of the value universe. Mid-capitalization stocks generally
outperformed both large and small-cap stocks for the period.

STRATEGIC REVIEW: AIDED BY STOCK SELECTION

      The Portfolio's outperformance was attributable to good stock selection in
the energy, producer durables, financial services and transportation sectors.
The Portfolio's overweighting in the energy sector also proved beneficial to its
performance. Negative contributors to the Portfolio's performance in the period
included its consumer discretionary and health care holdings, as well as its
underweighting in the utilities sector, as it outpaced the broader market in
2005.

ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

      With regard to noteworthy portfolio activity, our recent purchases
included Salem Communications (1.4% of the Portfolio's net assets as of December
31, 2005), a leading provider of religious radio programming. While the audience
for traditional radio formats has continued to decline, Salem's audience has
been growing. The market, however, was valuing Salem's shares similarly to other
radio broadcasters, which were trading at historically low valuations, at our
time of purchase. We also established a position in CACI International (1.6% of
the Portfolio's net assets as of December 31, 2005), a provider of information
technology solutions to government defense and intelligence agencies. Investors'
concerns about congressional budget delays led to a market price decline for the
shares, creating an attractive buying opportunity in our judgment.

      Our late-period sales included Eagle Materials, whose materials are used
in residential and commercial construction. The stock had rallied to reach our
sell target. We also pared our overall exposure to energy companies before
energy stocks tumbled in the fourth quarter of 2005, selling stocks such as
Oceaneering International that had performed well.

      Going forward, we will continue to seek to identify undervalued stocks of
small US companies. Using proprietary bottom-up equity research, we look for
stocks that are deeply discounted relative to our view of their upside
potential, with an emphasis on companies we believe stand to benefit from the
positive impact of a likely significant event.

      RETURNS REPRESENT PAST PERFORMANCE AND INCLUDE CHANGE IN SHARE PRICE AND
REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS. PAST PERFORMANCE CANNOT GUARANTEE
FUTURE RESULTS. THE CURRENT PERFORMANCE OF THE PORTFOLIO MAY BE LOWER OR HIGHER
THAN THE FIGURES SHOWN. RETURNS AND SHARE PRICE WILL FLUCTUATE, AND REDEMPTION
VALUE MAY BE MORE OR LESS THAN ORIGINAL COST. THE PERFORMANCE RESULTS DO NOT
REFLECT THE DEDUCTION OF TAXES THAT A SHAREHOLDER WOULD PAY ON PORTFOLIO
DISTRIBUTIONS OR THE REDEMPTION OF PORTFOLIO SHARES. PERFORMANCE INCLUDES THE
EFFECT OF DEDUCTING EXPENSES, BUT DOES NOT INCLUDE CHARGES AND EXPENSES
ATTRIBUTABLE TO ANY PARTICULAR VARIABLE CONTRACT OR PLAN. ACCORDINGLY, THE
PROSPECTUS OF THE SPONSORING PARTICIPATING INSURANCE COMPANY SEPARATE ACCOUNT OR
PLAN DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS SHOULD
BE CAREFULLY REVIEWED FOR INFORMATION ON RELEVANT CHARGES AND EXPENSES.
EXCLUDING THESE CHARGES AND EXPENSES FROM QUOTATIONS OF PERFORMANCE HAS THE
EFFECT OF INCREASING THE PERFORMANCE QUOTED, AND THE EFFECT OF THESE CHARGES
SHOULD BE CONSIDERED WHEN COMPARING PERFORMANCE TO THAT OF OTHER MUTUAL FUNDS.
PERFORMANCE INFORMATION CURRENT TO THE MOST RECENT MONTH-END IS AVAILABLE AT
WWW.CREDIT-SUISSE.COM/US.

CREDIT SUISSE TRUST -- SMALL CAP VALUE PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

INFORMATION ABOUT YOUR PORTFOLIO'S EXPENSES

      As an investor of the Portfolio, you incur two types of costs: ongoing
expenses and transaction costs. Ongoing expenses include management fees,
distribution and service (12b-1) fees and other Portfolio expenses. Examples of
transaction costs include sales charges (loads), redemption fees and account
maintenance fees, which are not shown in this section and which would result in
higher total expenses. The following table is intended to help you understand
your ongoing expenses of investing in the Portfolio and to help you compare
these expenses with the ongoing expenses of investing in other mutual funds. The
table is based on an investment of $1,000 made at the beginning of the six month
period ended December 31, 2005.

      The table illustrates your Portfolio's expenses in two ways:

      o     ACTUAL PORTFOLIO RETURN. This helps you estimate the actual dollar
            amount of ongoing expenses paid on a $1,000 investment in the
            Portfolio using the Portfolio's actual return during the period. To
            estimate the expenses you paid over the period, simply divide your
            account value by $1,000 (for example, an $8,600 account value
            divided by $1,000 = 8.6), then multiply the result by the number in
            the "Expenses Paid per $1,000" line under the share class you hold.

      o     HYPOTHETICAL 5% PORTFOLIO RETURN. This helps you to compare your
            Portfolio's ongoing expenses with those of other mutual funds using
            the Portfolio's actual expense ratio and a hypothetical rate of
            return of 5% per year before expenses. Examples using a 5%
            hypothetical fund return may be found in the shareholder reports of
            other mutual funds. The hypothetical account values and expenses may
            not be used to estimate the actual ending account balance or
            expenses you paid for the period.

      Please note that the expenses shown in these tables are meant to highlight
your ongoing expenses only and do not reflect any transaction costs, such as
sales charges (loads) or redemption fees. If these transaction costs had been
included, your costs would have been higher. The "Expenses Paid per $1,000" line
of the tables is useful in comparing ongoing expenses only and will not help you
determine the relative total expenses of owning different funds.

ANNUALIZED EXPENSE RATIOS*                                                 1.29%

_______________

*     EXPENSES ARE EQUAL TO THE PORTFOLIO'S ANNUALIZED EXPENSE RATIO MULTIPLIED
      BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY THE NUMBER OF
      DAYS IN THE MOST RECENT FISCAL HALF YEAR PERIOD, THEN DIVIDED BY 365.

      THE "EXPENSES PAID PER $1,000" AND THE "ANNUALIZED EXPENSE RATIOS" IN THE
      TABLES ARE BASED ON ACTUAL EXPENSES PAID BY THE PORTFOLIO DURING THE
      PERIOD, NET OF FEE WAIVERS AND/OR EXPENSE REIMBURSEMENTS. IF THOSE FEE
      WAIVERS AND/OR EXPENSE REIMBURSEMENTS HAD NOT BEEN IN EFFECT, THE
      PORTFOLIO'S ACTUAL EXPENSES WOULD HAVE BEEN HIGHER. EXPENSES DO NOT
      REFLECT ADDITIONAL CHARGES AND EXPENSES THAT ARE, OR MAY BE, IMPOSED UNDER
      THE VARIABLE CONTRACTS OR PLANS. SUCH CHARGES AND EXPENSES ARE DESCRIBED
      IN THE PROSPECTUS OF THE INSURANCE COMPANY SEPARATE ACCOUNT OR IN THE PLAN
      DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS. THE
      PORTFOLIO'S EXPENSES SHOULD BE CONSIDERED WITH THESE CHARGES AND EXPENSES
      IN EVALUATING THE OVERALL COST OF INVESTING IN THE SEPARATE ACCOUNT.

For more information, please refer to the Portfolio's prospectus.

CREDIT SUISSE TRUST -- SMALL CAP VALUE PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
December 31, 2005
- --------------------------------------------------------------------------------

NOTE 1. ORGANIZATION

      Credit Suisse Trust (the "Trust") is an open-end management investment
company registered under the Investment Company Act of 1940, as amended, and
currently offers eight managed investment portfolios of which one, the Small Cap
Value Portfolio (the "Portfolio"), is included in this report. The Portfolio is
a diversified investment fund that seeks a high level of growth of capital.
Shares of the Portfolio are not available directly to individual investors but
may be offered only through (a) variable annuity contracts and variable life
insurance contracts offered by separate accounts of certain insurance companies
and (b) tax-qualified pension and retirement plans. The Portfolio may not be
available in connection with a particular contract or plan. The Trust was
organized under the laws of The Commonwealth of Massachusetts as a business
trust on March 15, 1995.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      A) SECURITY VALUATION -- The net asset value of the Portfolio is
determined daily as of the close of regular trading on the New York Stock
Exchange, Inc. (the "Exchange") on each day the Exchange is open for business.
The Portfolio's equity investments are valued at market value, which is
generally determined using the closing price on the exchange or market on which
the security is primarily traded at the time of valuation (the "Valuation
Time"). If no sales are reported, equity investments are generally valued at the
most recent bid quotation as of the Valuation Time or at the lowest asked
quotation in the case of a short sale of securities. Debt securities with a
remaining maturity greater than 60 days are valued in accordance with the price
supplied by a pricing service, which may use a matrix, formula or other
objective method that takes into consideration market indices, yield curves and
other specific adjustments. Debt obligations that will mature in 60 days or less
are valued on the basis of amortized cost, which approximates market value,
unless it is determined that using this method would not represent fair value.
Investments in mutual funds are valued at the mutual fund's closing net asset
value per share on the day of valuation. Securities and other assets for which
market quotations are not readily available, or whose values have been
materially affected by events occurring before the Portfolio's Valuation Time
but after the close of the securities' primary markets, are valued at fair value
as determined in good faith by, or under the direction of, the Board of Trustees
under procedures established by the Board of Trustees. The Portfolio may utilize
a service provided by an independent

                                       17

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

third party which has been approved by the Board of Trustees to fair value
certain securities. When fair-value pricing is employed, the prices of
securities used by a fund to calculate its net asset value may differ from
quoted or published prices for the same securities.

      B) SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions
are accounted for on a trade date basis. Interest income is recorded on the
accrual basis. Dividends are recorded on the ex-dividend date. The cost of
investments sold is determined by use of the specific identification method for
both financial reporting and income tax purposes.

      C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net
investment income and distributions of net realized capital gains, if any, are
declared and paid at least annually. However, to the extent that a net realized
capital gain can be reduced by a capital loss carry- forward, such gain will not
be distributed. Income and capital gain distributions are determined in
accordance with federal income tax regulations, which may differ from accounting
principles generally accepted in the United States of America ("GAAP").

      D) FEDERAL INCOME TAXES -- No provision is made for federal taxes as it is
the Trust's intention to have the Portfolio continue to qualify for and elect
the tax treatment applicable to regulated investment companies under the
Internal Revenue Code of 1986, as amended, and to make the requisite
distributions to its shareholders, which will be sufficient to relieve it from
federal income and excise taxes.

      E) USE OF ESTIMATES -- The preparation of financial statements in
conformity with GAAP 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 revenues and expenses during the reporting period.
Actual results could differ from these estimates.

      F) SHORT-TERM INVESTMENTS -- The Portfolio, together with other
funds/portfolios advised by Credit Suisse Asset Management, LLC ("Credit
Suisse"), an indirect, wholly-owned subsidiary of Credit Suisse Group, pools
available cash into either a short-term variable rate time deposit issued by
State Street Bank and Trust Company ("SSB"), the Portfolio's custodian, or a
money

market fund advised by Credit Suisse. The short-term time deposit issued by SSB
is a variable rate account classified as a short-term investment.

      G) SECURITIES LENDING -- Loans of securities are required at all times to
be secured by collateral at least equal to 102% of the market value of domestic
securities on loan (including any accrued interest thereon) and 105% of the
market value of foreign securities on loan (including any accrued interest
thereon). Cash collateral received by the Portfolio in connection with
securities lending activity may be pooled together with cash collateral for
other funds/portfolios advised by Credit Suisse and may be invested in a variety
of investments, including certain Credit Suisse-advised funds, funds advised by
SSB, the Portfolio's securities lending agent, or money market instruments.
However, in the event of default or bankruptcy by the other party to the
agreement, realization and/or retention of the collateral may be subject to
legal proceedings.

      SSB has been engaged by the Portfolio to act as the Portfolio's securities
lending agent. The Portfolio's securities lending arrangement provides that the
Portfolio and SSB will share the net income earned from the securities lending
activities. During the year ended December 31, 2005, total earnings from the
Portfolio's investment in cash collateral received in connection with securities
lending arrangements was $144,421, of which $137,661 was rebated to borrowers
(brokers). The Portfolio retained $4,751 in income from the cash collateral
investment, and SSB, as lending agent, was paid $2,009. The Portfolio may also
be entitled to certain minimum amounts of income from its securities lending
activities. Securities lending income is accrued as earned.

NOTE 3. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

      Credit Suisse serves as investment adviser for the Portfolio. For its
investment advisory services, Credit Suisse is entitled to receive a fee,

      Credit Suisse Asset Management Securities, Inc. ("CSAMSI"), an affiliate

      For its co-administrative services, CSAMSI currently receives a fee
calculated at an annual rate of 0.10% of the Portfolio's average daily net
assets. For the year ended December 31, 2005, co-administrative services fees
earned by CSAMSI were $31,194.

      For its co-administrative services, SSB receives a fee, exclusive of
out-of-pocket expenses, calculated in total for all the Credit Suisse
funds/portfolios co-administered by SSB and allocated based upon relative
average net assets of each fund/portfolio, subject to an annual minimum fee. For
the year ended December 31, 2005, co-administrative services fees earned by SSB
(including out-of-pocket expenses) were $ 35,482.

      In addition to serving as the Portfolio's co-administrator, CSAMSI
currently serves as distributor of the Portfolio's shares without compensation.

      Merrill Corporation ("Merrill"), an affiliate of Credit Suisse, has been
engaged by the Portfolio to provide certain financial printing and fulfillment
services. For the year ended December 31, 2005, Merrill was paid $3,582 for its
services to the Portfolio.

NOTE 4. LINE OF CREDIT

      The Portfolio, together with other funds/portfolios advised by Credit
Suisse (collectively, the "Participating Funds"), participates in a $75 million
committed, unsecured line of credit facility ("Credit Facility") for temporary
or emergency purposes with Deutsche Bank, A.G. as administrative agent and
syndication agent and SSB as operations agent. Under the terms of the Credit
Facility, the Participating Funds pay an aggregate commitment fee at a rate of
0.10% per annum on the average unused amount of the Credit Facility, which is
allocated among the Participating Funds in such manner as is determined by the
governing Boards of the Participating Funds. In addition, the Participating
Funds pay interest on borrowings at the Federal Funds rate plus 0.50%. At
December 31, 2005, the Portfolio had no loans outstanding under the Credit
Facility. During the year ended December 31, 2005, the Portfolio had borrowings

      On December 31, 2005, the number of shareholders that held 5% or more of
the outstanding shares of the Portfolio was as follows:

                   NUMBER OF               APPROXIMATE PERCENTAGE

of individual shareholders.

NOTE 7. FEDERAL INCOME TAXES

      Income and capital gain distributions are determined in accordance with
federal income tax regulations, which may differ from GAAP.

CREDIT SUISSE TRUST -- SMALL CAP VALUE PORTFOLIO
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
December 31, 2005
- --------------------------------------------------------------------------------

NOTE 7. FEDERAL INCOME TAXES

      The tax characteristics of dividends and distributions paid during the
years ended December 31, 2005 and 2004, respectively, by the Portfolio were as
follows:

                  ORDINARY INCOME          LONG-TERM CAPITAL GAINS
              ----------------------       -----------------------

              --------      --------       --------      --------
              $387,358       $ --          $624,052        $ --

      The tax basis of components of distributable earnings differ from the
amounts reflected in the Statement of Assets and Liabilities by temporary
book/tax differences. These differences are primarily due to losses deferred on
wash sales and dividends received from Real Estate Investment Trusts.

      At December 31, 2005, the components of distributable earnings on a tax
basis for the Portfolio were as follows:

          Undistributed net investment income            $  345,453
          Accumulated net realized gain                   1,415,772
          Unrealized appreciation                         5,395,819
                                                         ----------
                                                         $7,157,044
                                                         ==========

      At December 31, 2005, the Portfolio had no capital loss carryforwards
available to offset possible future capital gains.

      At December 31, 2005, the identified cost for federal income tax purposes,
as well as the gross unrealized appreciation from investments for those
securities having an excess of value over cost, gross unrealized depreciation
from investments for those securities having an excess of cost over value and
the net unrealized appreciation from investments were as follows: $28,895,999,
$5,840,585, $(444,766) and $5,395,819, respectively.

      At December 31, 2005, the Portfolio reclassified $1,918 from accumulated
net realized gain on investments to undistributed net investment income, to
adjust for current period permanent book/tax differences which arose principally
from differing book/tax treatments of net operating losses, security litigation
and dividends received from Real Estate Investment Trusts. Net assets were not
affected by these reclassifications.

NOTE 8. CONTINGENCIES

      In the normal course of business, the Portfolio may provide general
indemnifications pursuant to certain contracts and organizational documents. The
Portfolio's maximum exposure under these arrangements is dependent on future
claims that may be made against the Portfolio and, therefore, cannot be
estimated; however, based on experience, the risk of loss from such claims is
considered remote.

CREDIT SUISSE TRUST -- SMALL CAP VALUE PORTFOLIO
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Board of Trustees of Credit Suisse Trust and Shareholders of
Credit Suisse Trust - Small Cap Value Portfolio:

      In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Small Cap Value Portfolio (the
"Portfolio"), a portfolio of the Credit Suisse Trust, at December 31, 2005, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended and the financial highlights
for each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Portfolio's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements 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 are free of
material misstatement. An audit 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, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 2005 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

CREDIT SUISSE TRUST -- SMALL CAP VALUE PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED)
- --------------------------------------------------------------------------------

      In approving the Advisory Agreement, the Board of Trustees, including the
Independent Trustees, considered the following factors with respect to the Small
Cap Value Portfolio (the "Portfolio"):

      INVESTMENT ADVISORY FEE RATES

      The Board reviewed and considered the contractual advisory fee rate of
0.875% of average daily net assets up to $100 million, declining to 0.75% on the
next $100 million and to 0.50% on assets in excess of $200 million, paid by the
Portfolio ("Contractual Advisory Fee"), which is reduced to 0.57% after
voluntary fee waivers and/or expense reimbursements ("Net Advisory Fee"), to
Credit Suisse Asset Management, LLC ("Credit Suisse") in light of the extent and
quality of the advisory services provided by Credit Suisse. The Board
acknowledged that fee waivers and expense reimbursements can be discontinued at
any time.

      Additionally, the Board received and considered information comparing the
Portfolio's Contractual Advisory Fee and the Portfolio's overall expenses with
those of funds in both the relevant expense group ("Expense Group") and universe
of funds (the "Expense Universe") provided by Lipper Inc., an independent
provider of investment company data.

      NATURE, EXTENT AND QUALITY OF THE SERVICES UNDER THE ADVISORY AGREEMENT

      The Board received and considered information regarding the nature, extent
and quality of services provided to the Portfolio by Credit Suisse under the
Advisory Agreement. The Board also noted information received at regular
meetings throughout the year related to the services rendered by Credit Suisse.
The Board reviewed background information about Credit Suisse, including its
Form ADV. The Board considered the background and experience of Credit Suisse's
senior management and the expertise of, and the amount of attention given to the
Portfolio by, senior personnel of Credit Suisse. In addition, the Board reviewed
the qualifications, backgrounds and responsibilities of the portfolio management
team primarily responsible for the day-to-day portfolio management of the
Portfolio and the extent of the resources devoted to research and analysis of
actual and potential investments. The Board also received and considered
information about the nature, extent and quality of services and fee rates
offered to other Credit Suisse clients for comparable services.

      PORTFOLIO PERFORMANCE

      The Board received and considered the one-, two- and three-year
performance of the Portfolio, along with comparisons, for all presented periods,
both to the relevant performance group ("Performance Group") and universe

                                       24




CREDIT SUISSE TRUST -- SMALL CAP VALUE PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

of funds ("Performance Universe") for the Portfolio. The Board was provided with
a description of the methodology used to arrive at the data for the funds
included in the Performance Group and the Performance Universe.

      The Board reviewed information comparing the performance of various Credit
Suisse Funds to performance benchmarks that the Board had previously established
and progress that had been made in certain instances toward achieving those
benchmarks. The Board also reviewed comparisons between the Portfolio and its
identified benchmark over various time periods.

      CREDIT SUISSE PROFITABILITY

      The Board received and considered a profitability analysis of Credit
Suisse based on the fees payable under the Advisory Agreement for the Portfolio,
including other relationships between the Portfolio on the one hand and Credit
Suisse affiliates on the other. The Board received profitability information for
the other funds in the Credit Suisse family of funds.

      ECONOMIES OF SCALE

      The Board considered whether economies of scale in the provision of
services to the Portfolio were being passed along to the shareholders.
Accordingly, the Board considered whether the breakpoints in the Portfolio's
advisory fee structure were appropriate or reasonable taking into consideration
economies of scale or other efficiencies that might accrue from increases in the
Portfolio's asset levels.

      OTHER BENEFITS TO CREDIT SUISSE

      The Board considered other benefits received by Credit Suisse and its
affiliates as a result of their relationship with the Portfolio. Such benefits
include, among others, research arrangements with brokers who execute
transactions on behalf of the Portfolio, administrative and brokerage
relationships with affiliates of Credit Suisse and benefits potentially derived
from an increase in Credit Suisse's businesses as a result of its relationship
with the Portfolio (such as the ability to market to shareholders other
financial products offered by Credit Suisse and its affiliates).

      The Board considered the standards applied in seeking best execution,
whether and to what extent soft dollar credits are sought and how any such
credits are utilized, any benefits that may be achieved by using an affiliated
broker and the existence of quality controls applicable to brokerage allocation
procedures. The Board also reviewed Credit Suisse's method for allocating
portfolio investment opportunities among its advisory clients.

CREDIT SUISSE TRUST -- SMALL CAP VALUE PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      CONCLUSIONS

      In selecting Credit Suisse, and approving the Advisory Agreement and the
investment advisory fee under such agreement, the Board concluded that:

      o     While the Contractual Advisory Fee was slightly below the median,
            the Net Advisory Fee was the lowest in the Portfolio's Expense Group
            and was considered reasonable.

      o     The Portfolio's one-year performance was above the median in the
            Performance Group and in the Performance Universe and superior to
            the Lipper index of similar funds. The Portfolio's two-year
            performance was at the median for the Performance Group and slightly
            below the median for the Performance Universe. The three-year
            performance was the lowest in the Performance Group and Performance
            Universe. The Board had previously identified the need to address
            the Portfolio's performance, and noted that Credit Suisse is in the
            process of addressing performance issues. The Board would continue
            to monitor steps taken by Credit Suisse to improve performance.

      o     Aside from performance (as described above), the Board was satisfied
            with the nature and extent of the investment advisory services
            provided to the Portfolio by Credit Suisse and that, based on
            dialogue with management and counsel, the services provided by
            Credit Suisse under the Advisory Agreement is typical of, and
            consistent with, those provided to similar mutual funds by other
            investment advisers. The Board understood that Credit Suisse had
            addressed or was in the process of addressing any performance
            issues.

      o     In light of the costs of providing investment management and other
            services to the Portfolio and Credit Suisse's ongoing commitment to
            the Portfolio, the profits and other ancillary benefits that Credit
            Suisse and its affiliates received were considered reasonable.

      o     Credit Suisse's profitability based on fees payable under the
            Advisory Agreement was reasonable in light of the nature, extent and
            quality of the services provided to the Portfolio thereunder.

      o     In light of the amount of the Net Advisory Fee, the Portfolio's
            current fee structure was considered reasonable.

      No single factor reviewed by the Board was identified by the Board as the
principal factor in determining whether to approve the Advisory Agreement. The
Independent Trustees were advised by separate independent legal counsel
throughout the process.

CREDIT SUISSE TRUST--EMERGING MARKETS PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT
December 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

                                                                January 19, 2006

Dear Shareholder:

      For the 12 months ended December 31, 2005, Credit Suisse Trust--Emerging
Markets Portfolio1 (the "Portfolio") had a gain of 27.84%, vs. an increase of
34.54% for the Morgan Stanley Capital International Emerging Markets Index.2

MARKET OVERVIEW: EMERGING MARKETS OUTPERFORM IN GLOBAL RALLY

      The period was a positive one for stock markets around the world, aided by
optimism over global economic growth and generally favorable earnings reports.
Emerging markets as a group had overall strong returns in absolute terms and as
compared with developed stock markets, helped in part by high and rising
commodity prices, which for many commodity-exporting emerging economies resulted
in stronger financial profiles.

      By region, Latin America outpaced the broad emerging market universe,
reflecting strong returns from Brazil and Mexico. Asia was positive across the
board, but as a region underperformed. The Europe/Middle East/Africa segment
(EMEA) was in the middle of the pack, though certain of its smaller markets
posted large gains for the period.

STRATEGIC REVIEW: ASIAN HOLDINGS UNDERPERFORM WHILE EMEA STOCKS SHINE

      The Portfolio participated in the broad rally in emerging markets,
although it underperformed its benchmark, which we attribute in large part to
its positioning in Asia. Most specifically, we were underweighted in Taiwanese
technology-exporting companies, which outperformed the domestic companies we
favored, and had limited exposure to certain South Korean stocks that had strong
showings. Within Latin America, stock selection in Chile detracted from
performance, countering good performance from the Portfolio's holdings in
Mexico. Elsewhere, the Portfolio was aided by good stock selection within EMEA,
in particular with regard to its Russian and South African holdings. This more
than offset the Portfolio's underweighting in smaller EMEA markets, such as
Egypt, that outperformed.

      In terms of regional allocation, as of the end of the period we were
modestly overweighted in Latin America, with a focus on Brazil and Mexico, where
we believe earnings growth and interest rate reductions could support equities.
We had an underweighting in EMEA as a whole, primarily due to our
underweightings in the smaller central European markets, lack of exposure to
smaller Middle Eastern markets and our underweighting in South Africa. We

                                        1

ended the period overweighted in Russia, which we think could benefit from high
oil prices and a related improvement in domestic liquidity. We remain broadly
neutral in Asia, with an emphasis on China, South Korea and, to a lesser extent,
Thailand. As of the end of the period, Taiwan and India were underweighted
positions in the Portfolio, as were certain smaller southeastern Asian markets.

      In the wake of several years of strong absolute and relative performance,
emerging markets could be vulnerable to any negative shocks (such as rising US
short-term rates or unforeseen oil price spikes). Still, against what we expect
to be a fairly benign global scenario this year, we believe that investors will
continue find emerging markets compelling, given the valuation and earnings
differentials with developed markets and the generally favorable domestic
economic conditions prevailing in many developing countries.

      RETURNS REPRESENT PAST PERFORMANCE AND INCLUDE CHANGES IN SHARE PRICE AND
REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS. PAST PERFORMANCE CANNOT GUARANTEE
FUTURE RESULTS. THE CURRENT PERFORMANCE OF THE PORTFOLIO MAY BE LOWER OR HIGHER
THAN THE FIGURES SHOWN. RETURNS AND SHARE PRICE WILL FLUCTUATE, AND REDEMPTION
VALUE MAY BE MORE OR LESS THAN ORIGINAL COST. THE PERFORMANCE RESULTS DO NOT
REFLECT THE DEDUCTION OF TAXES THAT A SHAREHOLDER WOULD PAY ON PORTFOLIO
DISTRIBUTIONS OR THE REDEMPTION OF PORTFOLIO SHARES. PERFORMANCE INCLUDES THE
EFFECT OF DEDUCTING EXPENSES, BUT DOES NOT INCLUDE CHARGES AND EXPENSES
ATTRIBUTABLE TO ANY PARTICULAR VARIABLE CONTRACT OR PLAN. ACCORDINGLY, THE
PROSPECTUS OF THE SPONSORING PARTICIPATING INSURANCE COMPANY SEPARATE ACCOUNT OR
PLAN DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS SHOULD
BE CAREFULLY REVIEWED FOR INFORMATION ON RELEVANT CHARGES AND EXPENSES.
EXCLUDING THESE CHARGES AND EXPENSES FROM QUOTATIONS OF PERFORMANCE HAS THE
EFFECT OF INCREASING THE PERFORMANCE QUOTED, AND THE EFFECT OF THESE CHARGES
SHOULD BE CONSIDERED WHEN COMPARING PERFORMANCE TO THAT OF OTHER MUTUAL FUNDS.
PERFORMANCE INFORMATION CURRENT TO THE MOST RECENT MONTH-END IS AVAILABLE AT
WWW.CREDIT-SUISSE.COM/US.

ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)

INFORMATION ABOUT YOUR PORTFOLIO'S EXPENSES

      As an investor of the Portfolio, you incur two types of costs: ongoing
expenses and transaction costs. Ongoing expenses include management fees,
distribution and service (12b-1) fees and other Portfolio expenses. Examples of
transaction costs include sales charges (loads), redemption fees and account
maintenance fees, which are not shown in this section and which would result in
higher total expenses. The following table is intended to help you understand
your ongoing expenses of investing in the Portfolio and to help you compare
these expenses with the ongoing expenses of investing in other mutual funds. The
table is based on an investment of $1,000 made at the beginning of the six month
period ended December 31, 2005.

      The table illustrates your Portfolio's expenses in two ways:

      o     ACTUAL PORTFOLIO RETURN. This helps you estimate the actual dollar
            amount of ongoing expenses paid on a $1,000 investment in the
            Portfolio using the Portfolio's actual return during the period. To
            estimate the expenses you paid over the period, simply divide your
            account value by $1,000 (for example, an $8,600 account value
            divided by $1,000 = 8.6), then multiply the result by the number in
            the "Expenses Paid per $1,000" line under the share class you hold.

      o     HYPOTHETICAL 5% PORTFOLIO RETURN. This helps you to compare your
            Portfolio's ongoing expenses with those of other mutual funds using
            the Portfolio's actual expense ratio and a hypothetical rate of
            return of 5% per year before expenses. Examples using a 5%
            hypothetical fund return may be found in the shareholder reports of
            other mutual funds. The hypothetical account values and expenses may
            not be used to estimate the actual ending account balance or
            expenses you paid for the period.

      Please note that the expenses shown in these tables are meant to highlight
your ongoing expenses only and do not reflect any transaction costs, such as
sales charges (loads) or redemption fees. If these transaction costs had been
included, your costs would have been higher. The "Expenses Paid per $1,000" line
of the tables is useful in comparing ongoing expenses only and will not help you
determine the relative total expenses of owning different funds.

_________________

*     EXPENSES ARE EQUAL TO THE PORTFOLIO'S ANNUALIZED EXPENSE RATIO MULTIPLIED
      BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY THE NUMBER OF
      DAYS IN THE MOST RECENT FISCAL HALF YEAR PERIOD, THEN DIVIDED BY 365.

      THE "EXPENSES PAID PER $1,000" AND THE "ANNUALIZED EXPENSE RATIOS" IN THE
      TABLES ARE BASED ON ACTUAL EXPENSES PAID BY THE PORTFOLIO DURING THE
      PERIOD, NET OF FEE WAIVERS AND/OR EXPENSE REIMBURSEMENTS. IF THOSE FEE
      WAIVERS AND/OR EXPENSE REIMBURSEMENTS HAD NOT BEEN IN EFFECT, THE
      PORTFOLIO'S ACTUAL EXPENSE WOULD HAVE BEEN HIGHER. EXPENSES DO NOT REFLECT
      ADDITIONAL CHARGES AND EXPENSES THAT ARE, OR MAY BE, IMPOSED UNDER THE
      VARIABLE CONTRACTS OR PLANS. SUCH CHARGES AND EXPENSES ARE DESCRIBED IN
      THE PROSPECTUS OF THE INSURANCE COMPANY SEPARATE ACCOUNT OR IN THE PLAN
      DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS. THE
      PORTFOLIO'S EXPENSES SHOULD BE CONSIDERED WITH THESE CHARGES AND EXPENSES

CREDIT SUISSE TRUST--EMERGING MARKETS PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
December 31, 2005
- --------------------------------------------------------------------------------

NOTE 1. ORGANIZATION

      Credit Suisse Trust (the "Trust") is an open-end management investment
company registered under the Investment Company Act of 1940, as amended, and
currently offers eight managed investment portfolios of which one, the Emerging
Markets Portfolio (the "Portfolio"), is included in this report. The Portfolio
is a diversified investment fund that seeks long-term growth of capital. Shares
of the Portfolio are not available directly to individual investors but may be
offered only through (a) variable annuity contracts and variable life insurance
contracts offered by separate accounts of certain insurance companies and (b)
tax-qualified pension and retirement plans. The Portfolio may not be available
in connection with a particular contract or plan. The Trust was organized under
the laws of The Commonwealth of Massachusetts as a business trust on March 15,
1995.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      A) SECURITY VALUATION - The net asset value of the Portfolio is determined
daily as of the close of regular trading on the New York Stock Exchange, Inc.
(the "Exchange") on each day the Exchange is open for business. The Portfolio's
equity investments are valued at market value, which is generally determined
using the closing price on the exchange or market on which the security is
primarily traded at the time of valuation (the "Valuation Time"). If no sales
are reported, equity investments are generally valued at the most recent bid
quotation as of the Valuation Time or at the lowest asked quotation in the case
of a short sale of securities. Debt securities with a remaining maturity greater
than 60 days are valued in accordance with the price supplied by a pricing
service, which may use a matrix, formula or other objective method that takes
into consideration market indices, yield curves and other specific adjustments.
Debt obligations that will mature in 60 days or less are valued on the basis of
amortized cost, which approximates market value, unless it is determined that
using this method would not represent fair value. Investments in mutual funds
are valued at the mutual fund's closing net asset value per share on the day of
valuation. Securities and other assets for which market quotations are not
readily available, or whose values have been materially affected by events
occurring before the Portfolio's Valuation Time but after the close of the
securities' primary markets, are valued at fair value as determined in good
faith by, or under the direction of, the Board of Trustees under procedures
established by the Board of Trustees. The Portfolio may utilize a service
provided by an independent third party which has been approved by

                                       21




CREDIT SUISSE TRUST--EMERGING MARKETS PORTFOLIO

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

the Board of Trustees to fair value certain securities. When fair-value pricing
is employed, the prices of securities used by a fund to calculate its net asset
value may differ from quoted or published prices for the same securities.

      B) FOREIGN CURRENCY TRANSACTIONS - The books and records of the Portfolio
are maintained in U.S. dollars. Transactions denominated in foreign currencies
are recorded at the current prevailing exchange rates. All assets and
liabilities denominated in foreign currencies are translated into U.S. dollar
amounts at the current exchange rate at the end of the period. Translation gains
or losses resulting from changes in the exchange rate during the reporting
period and realized gains and losses on the settlement of foreign currency
transactions are reported in the results of operations for the current period.
The Portfolio does not isolate that portion of realized gains and losses on
investments in EQUITY securities which is due to changes in the foreign exchange
rate from that which is due to changes in market prices of equity securities.
The Portfolio isolates that portion of realized gains and losses on investments
in DEBT securities which is due to changes in the foreign exchange rate from
that which is due to changes in market prices of debt securities.

      C) SECURITY TRANSACTIONS AND INVESTMENT INCOME - Security transactions are
accounted for on a trade date basis. Interest income is recorded on the accrual
basis. Dividends are recorded on the ex-dividend date. The cost of investments
sold is determined by use of the specific identification method for both
financial reporting and income tax purposes.

      D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS - Dividends from net
investment income and distributions of net realized capital gains, if any, are
declared and paid at least annually. However, to the extent that a net realized
capital gain can be reduced by a capital loss carryforward, such gain will not
be distributed. Income and capital gain distributions are determined in
accordance with federal income tax regulations, which may differ from accounting
principles generally accepted in the United States of America ("GAAP").

      E) FEDERAL INCOME TAXES - No provision is made for federal taxes as it is
the Trust's intention to have the Portfolio continue to qualify for and elect
the tax treatment applicable to regulated investment companies under the
Internal Revenue Code of 1986, as amended, and to make the requisite
distributions to

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

its shareholders, which will be sufficient to relieve it from federal income and
excise taxes.

      F) USE OF ESTIMATES - The preparation of financial statements in
conformity with GAAP 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 revenues and expenses during the reporting period.
Actual results could differ from these estimates.

      G) SHORT-TERM INVESTMENTS - The Portfolio, together with other
funds/portfolios advised by Credit Suisse Asset Management, LLC ("Credit
Suisse"), an indirect, wholly-owned subsidiary of Credit Suisse Group, pools
available cash into either a short-term variable rate time deposit issued by
State Street Bank and Trust Company ("SSB"), the Portfolio's custodian, or a
money market fund advised by Credit Suisse. The short-term time deposit issued
by SSB is a variable rate account classified as a short-term investment.

      H) FORWARD FOREIGN CURRENCY CONTRACTS - The Portfolio may enter into
forward foreign currency contracts for the purchase or sale of a specific
foreign currency at a fixed price on a future date. Risks may arise upon
entering into these contracts from the potential inability of counterparties to
meet the terms of their contracts and from unanticipated movements in the value
of a foreign currency. The Portfolio will enter into forward foreign currency
contracts primarily for hedging purposes. Forward foreign currency contracts are
adjusted by the daily forward exchange rate of the underlying currency, and any
gains or losses are recorded for financial statement purposes as unrealized
until the contract settlement date or an offsetting position is entered into. At
December 31, 2005, the Portfolio had no open forward foreign currency contracts.

      I) SECURITIES LENDING - Loans of securities are required at all times to
be secured by collateral at least equal to 102% of the market value of domestic
securities on loan (including any accrued interest thereon) and 105% of the
market value of foreign securities on loan (including any accrued interest
thereon). Cash collateral received by the Portfolio in connection with
securities lending activity may be pooled together with cash collateral for
other funds/portfolios advised by Credit Suisse and may be invested in a variety
of investments, including certain Credit Suisse-advised funds, funds advised by

                                       23

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

SSB, the Portfolio's securities lending agent, or money market instruments.
However, in the event of default or bankruptcy by the other party to the
agreement, realization and/or retention of the collateral may be subject to
legal proceedings.

      SSB has been engaged by the Portfolio to act as the Portfolio's securities
lending agent. The Portfolio's securities lending arrangement provides that the
Portfolio and SSB will share the net income earned from the securities lending
activities. During the year ended December 31, 2005, total earnings from the
Portfolio's investment in cash collateral received in connection with securities
lending arrangements was $296,288, of which $263,518 was rebated to borrowers
(brokers). The Portfolio retained $22,883 in income from the cash collateral
investment and SSB, as lending agent, was paid $9,887. The Portfolio may also be
entitled to certain minimum amounts of income from its securities lending
activities. Securities lending income is accrued as earned.

      J) OTHER - The Portfolio may invest in securities of foreign countries and
governments which involve certain risks in addition to those inherent in
domestic investments. Such risks generally include, among others, currency risk
(fluctuations in currency exchange rates), information risk (key information may
be inaccurate or unavailable) and political risk (expropriation, nationalization
or the imposition of capital or currency controls or punitive taxes). Other
risks of investing in foreign securities include liquidity and valuation risks.

      The Portfolio's investments in securities of issuers located in less
developed countries considered to be "emerging markets" involve risks in
addition to those generally applicable to foreign securities. Focusing on
emerging (less developed) markets involves higher levels of risk, including
increased currency, information, liquidity, market, political and valuation
risks. Deficiencies in regulatory oversight, market infrastructure, shareholder
protections and company laws could expose the Portfolio to operational and other
risks as well. Some countries may have restrictions that could limit the
Portfolio's access to attractive investment opportunities. Additionally,
emerging markets often face serious economic problems (such as high external
debt, inflation and unemployment) that could subject the Portfolio to increased
volatility or substantial declines in value.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      The Portfolio may be subject to taxes imposed by countries in which it
invests with respect to its investments in issuers existing or operating in such
countries. Such taxes are generally based on income earned or repatriated and
capital gains realized on the sale of such investments. The Portfolio accrues
such taxes when the related income or capital gains are earned.

NOTE 3. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

      Credit Suisse serves as investment adviser for the Portfolio. For its
investment advisory services, Credit Suisse is entitled to receive a fee from
the Portfolio at an annual rate of 1.25% of the Portfolio's average daily net
assets. For the year ended December 31, 2005, investment advisory fees earned
and voluntarily waived were $1,686,255 and $342,098, respectively. Credit Suisse
will not recapture from the Portfolio any fees it waived during the fiscal year
ended December 31, 2005. Fee waivers and reimbursements are voluntary and may be
discontinued by Credit Suisse at any time.

      Credit Suisse Asset Management Limited (U.K.) ("Credit Suisse U.K.") and
Credit Suisse Asset Management Limited (Australia) ("Credit Suisse Australia"),
affiliates of Credit Suisse, are sub-investment advisers to the Portfolio (the
"Sub-Advisers"). Credit Suisse U.K's and Credit Suisse Australia's
sub-investment advisory fees are paid by Credit Suisse out of Credit Suisse's
net investment advisory fee and are not paid by the Portfolio.

      Credit Suisse Asset Management Securities, Inc. ("CSAMSI"), an affiliate
of Credit Suisse, and SSB serve as co-administrators to the Portfolio.

      For its co-administrative services, CSAMSI currently receives a fee
calculated at an annual rate of 0.10% of the Portfolio's average daily net
assets. For the year ended December 31, 2005, co-administrative services fees
earned by CSAMSI were $134,900.

      For its co-administrative services, SSB receives a fee, exclusive of
out-of-pocket expenses calculated in total for all the Credit Suisse
funds/portfolios co-administered by SSB and allocated based upon relative
average net assets of each fund/portfolio, subject to an annual minimum fee. For
the year ended December 31, 2005, co-administrative services fees earned by SSB
(including out-of-pocket expenses) were $106,932.

      In addition to serving as the Portfolio's co-administrator, CSAMSI
currently serves as distributor of the Portfolio's shares without compensation.

engaged by the Portfolio to provide certain financial printing and fulfillment
services. For the year ended December 31, 2005, Merrill was paid $8,048 for its
services to the Portfolio.

NOTE 4. LINE OF CREDIT

      The Portfolio, together with other funds/portfolios advised by Credit
Suisse (collectively, the "Participating Funds"), participates in a $75 million
committed, unsecured line of credit facility ("Credit Facility") for temporary
or emergency purposes with Deutsche Bank, A.G. as administrative agent and
syndication agent and SSB as operations agent. Under the terms of the Credit
Facility, the Participating Funds pay an aggregate commitment fee at a rate of
0.10% per annum on the average unused amount of the Credit Facility, which is
allocated among the Participating Funds in such manner as is determined by the
governing Boards of the Participating Funds. In addition, the Participating
Funds pay interest on borrowings at the Federal Funds rate plus 0.50%. At
December 31, 2005 and during the year ended December 31, 2005, the Portfolio had
no borrowings under the Credit Facility.

NOTE 5. PURCHASES AND SALES OF SECURITIES

      For the year ended December 31, 2005, purchases and sales of investment
securities (excluding short-term investments) were $133,149,699 and
$100,785,041, respectively.

NOTE 6. CAPITAL SHARE TRANSACTIONS

      On December 31, 2005, the number of shareholders that held 5% or more of
the outstanding shares was as follows:

           NUMBER OF                      APPROXIMATE PERCENTAGE
          SHAREHOLDERS                    OF OUTSTANDING SHARES
          ------------                    ----------------------
               6                                   95%

      Some of the shareholders are omnibus accounts, which hold shares on behalf
of individual shareholders.

NOTE 7. FEDERAL INCOME TAXES

      Income and capital gain distributions are determined in accordance with
federal income tax regulations, which may differ from GAAP.

      The tax characteristics of dividends paid during the years ended December
31, 2005, and 2004, respectively, by the Portfolio were as follows:

                           ORDINARY INCOME
                           ---------------
                       2005                   2004
                     --------               --------
                     $986,165               $257,121

      The tax basis of components of distributable earnings differ from the
amounts reflected in the Statement of Assets and Liabilities by temporary
book/tax differences. These differences are primarily due to mark-to-market of
foreign currency transactions, losses deferred due to wash sales, post-October
losses and the mark-to-market income from Passive Foreign Investment Companies.

      At December 31, 2005, the components of distributable earnings on a tax
basis for the Portfolio was as follows:

        Undistributed net investment income            $ 1,930,527
        Accumulated net realized gain                    2,149,933
        Unrealized appreciation                         51,697,471
        Deferral of post-October currency losses           (77,933)
                                                       -----------
                                                       $55,699,998
                                                       ===========

      During the tax year ended December 31, 2005, the Portfolio utilized
$5,569,803 of the capital loss carryforward.

NOTE 7. FEDERAL INCOME TAXES

      Under current tax law, certain capital losses realized after October 31
within a taxable year may be deferred and treated as occurring on the first day
of the following tax year. For the tax period ended December 31, 2005, the
Portfolio elected to defer net losses arising between November 1, 2005 and
December 31, 2005 as follows:

                                    CURRENCY
                                    --------
                                     $77,933

      As of December 31, 2005, the identified cost for federal income tax
purposes, as well as the gross unrealized appreciation from investments for
those securities having an excess of value over cost, gross unrealized
depreciation from investments for those securities having an excess of cost over
value and the net unrealized appreciation from investments were as follows:
$146,595,662 $53,837,534, $(2,024,328) and $51,813,206, respectively.

      At December 31, 2005, the Portfolio reclassified $189,232 from
undistributed net investment income to accumulated net realized loss from
investments, to adjust for current year permanent book/tax differences which
arose principally from differing book/tax treatments of foreign currency
transactions, realized capital gains tax and security litigation, and the sale
of Passive Foreign Investment Companies. Net assets were not affected by these
reclassifications.

NOTE 8. CONTINGENCIES

      In the normal course of business, the Portfolio may provide general
indemnifications pursuant to certain contracts and organizational documents. The
Portfolio's maximum exposure under these arrangements is dependent on future
claims that may be made against the Portfolio and, therefore, cannot be
estimated; however, based on experience, the risk of loss from such claims is
considered remote.

CREDIT SUISSE TRUST--EMERGING MARKETS PORTFOLIO
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Board of Trustees of Credit Suisse Trust and Shareholders of Credit
Suisse Trust - Emerging Markets Portfolio:

      In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Emerging Markets Portfolio (the
"Portfolio"), a portfolio of the Credit Suisse Trust, at December 31, 2005, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended and the financial highlights
for each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Portfolio's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements 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 are free of
material misstatement. An audit 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, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 2005 by
correspondence with the custodian, provide a reasonable basis for our opinion.

CREDIT SUISSE TRUST--EMERGING MARKETS PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED)
- --------------------------------------------------------------------------------

      In approving the Advisory and Sub-Advisory Agreements, the Board of
Trustees, including the Independent Trustees, considered the following factors
with respect to the Emerging Markets Portfolio (the "Portfolio"):

INVESTMENT ADVISORY FEE RATES

      The Board reviewed and considered the contractual advisory fee rate of
1.25% for the Portfolio ("Contractual Advisory Fee") in light of the extent and
quality of the advisory services provided by Credit Suisse Asset Management, LLC
("Credit Suisse") or Credit Suisse Asset Management Limited U.K. ("Credit Suisse
U.K.") and Credit Suisse Asset Management Limited Australia ("Credit Suisse
Australia"). The Board also reviewed and considered the fee waivers and/or
expense reimbursement arrangements currently in place for the Portfolio and
considered the actual fee rates of 0.96% paid by the Portfolio after taking
waivers and reimbursements into account ("Net Advisory Fee"). The Board
acknowledged that the fee waivers and reimbursements could be discontinued at
any time. In addition, the Board noted that the compensation paid to Credit
Suisse U.K. and Credit Suisse Australia (collectively, the "Sub-Advisers") does
not increase the fees or expenses otherwise incurred by the Portfolio's
shareholders.

      Additionally, the Board received and considered information comparing the
Portfolio's Contractual Advisory Fee and Net Advisory Fee and the Portfolio's
overall expenses with those of funds in both the relevant expense group ("Peer
Group") and universe of funds (the "Universe") provided by Lipper Inc., an
independent provider of investment company data.

      NATURE, EXTENT AND QUALITY OF THE SERVICES UNDER THE ADVISORY AND
      SUB-ADVISORY AGREEMENTS

      The Board received and considered information regarding the nature, extent
and quality of services provided to the Portfolio by Credit Suisse under the
Advisory Agreement and by the Sub-Advisers under the Sub-Advisory Agreements.
The Board also noted information received at regular meetings throughout the
year related to the services rendered by Credit Suisse and the Sub-Advisers. The
Board reviewed background information about Credit Suisse and the Sub-Advisers,
including their respective Form ADV. The Board considered the background and
experience of both Credit Suisse's and the Sub-Advisers' senior management and
the expertise of, and the amount of attention given to the Portfolio by, senior
personnel of Credit Suisse and the Sub-Advisers. With respect to the
Sub-Advisers, the Board also considered their expertise in managing the types of
global investments that the Portfolio utilizes in its investment strategy. In
addition, the Board reviewed the qualifications, backgrounds and
responsibilities of the portfolio management team primarily responsible for the
day-to-day portfolio management of the Portfolio and the extent of the resources
devoted to research and analysis of actual and potential investments. The Board
also received and considered information about the nature, extent and quality of
services and fee rates offered to other Credit Suisse clients for comparable
services.

      In approving the Sub-Advisory Agreements, the Board also considered the
benefits of retaining Credit Suisse's United Kingdom and Australian affiliates
given the increased complexity of the domestic and international securities
markets,

CREDIT SUISSE TRUST--EMERGING MARKETS PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

specifically that retention of Credit Suisse U.K. and Credit Suisse Australia
expands the universe of companies and countries from which investment
opportunities could be sought and enhances the ability of the Portfolio to
obtain the best price and execution on trades in international markets.

      PORTFOLIO PERFORMANCE

      The Board received and considered the one-, two-, three-, four- and
five-year performance of the Portfolio, along with comparisons, for all
presented periods, both to the relevant performance group ("Performance Group")
and universe of funds ("Performance Universe") for the Portfolio. The Board was
provided with a description of the methodology used to arrive at the funds
included in the Performance Group and the Performance Universe.

      The Board reviewed information comparing the performance of various Credit
Suisse Funds to performance benchmarks that the Board had previously established
and progress that had been made in certain instances toward achieving those
benchmarks. The Board also reviewed comparisons between the Portfolio and its
identified benchmark over various time periods.

      CREDIT SUISSE PROFITABILITY

      The Board received and considered a profitability analysis of Credit
Suisse based on the fees payable under the Advisory Agreement for the Portfolio,
including any fee waivers or fee caps, as well as other relationships between
the Portfolio on the one hand and Credit Suisse affiliates on the other. The
Board received profitability information for the other funds in the Credit
Suisse family of funds.

      ECONOMIES OF SCALE

      The Board considered whether economies of scale in the provision of
services to the Portfolio were being passed along to the shareholders.
Accordingly, the Board considered whether alternative fee structures (such as
breakpoint fee structures) would be more appropriate or reasonable taking into
consideration economies of scale or other efficiencies that might accrue from
increases in the Portfolio's asset levels.

      OTHER BENEFITS TO CREDIT SUISSE

      The Board considered other benefits received by Credit Suisse, the
Sub-Advisers and their affiliates as a result of their relationship with the
Portfolio. Such benefits include, among others, research arrangements with
brokers who execute transactions on behalf of the Portfolio, administrative and
brokerage relationships with affiliates of Credit Suisse and the Sub-Advisers
and benefits potentially derived from an increase in Credit Suisse's and the
Sub-Advisers' businesses as a result of their relationship with the Portfolio
(such as the ability to market to shareholders other financial products offered
by Credit Suisse, the Sub-Advisers and their affiliates).

      The Board considered the standards applied in seeking best execution,
whether and to what extent soft dollar credits are sought and how any such
credits are utilized, any benefits that may be achieved by using an affiliated
broker and the existence of quality controls applicable to brokerage allocation
procedures. The Board also reviewed Credit Suisse's and the Sub-Advisers' method
for allocating portfolio investment opportunities among their advisory clients.

CREDIT SUISSE TRUST--EMERGING MARKETS PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      CONCLUSIONS

      In selecting Credit Suisse and the Sub-Advisers, and approving the
Advisory Agreement and the investment advisory fee under such agreement and the
Sub-Advisory Agreements, the Board concluded that:

      o     Although the Contractual Advisory Fee was greater than the median of
            the Portfolio's Peer Group, the Net Advisory Fee was lower than the
            median of the Portfolio's Peer Group. In addition, the Board
            recognized that Credit Suisse has historically evidenced a
            willingness to waive fees. The Board considered that the Net
            Advisory Fee would decrease to 0.91% when the additional voluntary
            fee waiver (described below) is taken into account. The Board
            considered the Net Advisory Fee to be reasonable.

      o     The Portfolio's one-, two-, three-, four- and five-year performance
            lagged that of the Portfolio's Performance Group and Performance
            Universe. The Board had previously identified the need to address
            the Portfolio's performance, and noted that Credit Suisse was in the
            process of addressing performance issues. After discussion with the
            Board, Credit Suisse had agreed to an additional one-year voluntary
            fee reduction of five basis points. The Board would continue to
            monitor steps undertaken by Credit Suisse to improve performance.

      o     Aside from performance (as described above), the Board was satisfied
            with the nature, extent and quality of the investment advisory
            services provided to the Portfolio by Credit Suisse and the
            Sub-Advisers and that, based on dialogue with management and
            counsel, the services provided by Credit Suisse under the Advisory
            Agreement and by the Sub-Advisers under the Sub-Advisory Agreements
            are typical of, and consistent with, those provided to mutual funds
            by other investment advisers. The Board understood that Credit
            Suisse was in the process of addressing performance issues.

      o     In light of the costs of providing investment management and other
            services to the Portfolio and Credit Suisse's ongoing commitment to
            the Portfolio and willingness to cap fees and expenses, the profits
            and other ancillary benefits that Credit Suisse and its affiliates
            received were considered reasonable.

      o     Credit Suisse's profitability based on fees payable under the
            Advisory Agreement was reasonable in light of the nature, extent and
            quality of the services provided to the Portfolio thereunder.

      o     In light of the relatively small size of the Portfolio, the amount
            of the Net Advisory Fee and the additional voluntary fee reduction,
            the Portfolio's current fee structure (without breakpoints) was
            considered reasonable.

      No single factor reviewed by the Board was identified by the Board as the
principal factor in determining whether to approve the Advisory Agreement and
the Sub-Advisory Agreements. The Independent Trustees were advised by separate
independent legal counsel throughout the process.

ANNUAL INVESTMENT ADVISER'S REPORT
December 31, 2005 (unaudited)

                                                                January 26, 2006

Dear Shareholder:

      For the 12 months ended December 31, 2005, Credit Suisse Trust -- Blue
Chip Portfolio 1 (the "Portfolio") had a gain of 5.78%, vs. an increase of 4.91%
for the S&P 500 Index. 2

THE MARKET: POSITIVE DESPITE RISING ENERGY COSTS, INTEREST RATES

      The period was an overall positive one for equities. Stocks initially
struggled, but rallied into the summer, aided by benign inflation data and good
earnings reports from a number of visible companies. To be sure, headwinds were
ever-present, notably in the form of hurricane activity, surging energy prices
and a Federal Reserve that continued to raise short-term interest rates in small
but steady increments. In the face of all this, the economy nonetheless appeared
resilient, at least as of late 2005: Third-quarter GDP growth was reported at an
annualized rate of 4.1%, the tenth consecutive quarter of 3% or greater growth.
The earnings backdrop remained generally supportive late in the year.

      In the market, high energy prices helped drive the outperformance of
energy related stocks, which, despite some late-period weakness, outpaced all
other economic sectors in the period. This was reflected in the outperformance
of value stocks over growth stocks, as energy companies comprise a relatively
large portion of the value universe. Mid-capitalization stocks generally
outperformed both large- and small-cap stocks for the period.

STRATEGIC REVIEW: CONSUMER STOCKS AID PERFORMANCE

      The Portfolio outperformed its benchmark in the period, aided by good
stock selection in the consumer area, in particular retail companies. The
Portfolio energy holdings also supported performance, in both absolute and
relative terms. On the negative side, relatively speaking, the Portfolio's
industrials and technology stocks modestly detracted from its performance.

      As a reminder, effective June 1, 2005, the Credit Suisse Quantitative
Resources Group manages the Portfolio. We employ quantitative portfolio
techniques to select portfolio securities. Our quantitative models are designed
to (1) forecast the expected relative returns of stocks by analyzing a number of
fundamental factors, (2) to identify stocks that might likely suffer price
declines if market conditions deteriorate and limit the Portfolio's exposure to
such low

      RETURNS REPRESENT PAST PERFORMANCE AND INCLUDE CHANGE IN SHARE PRICE AND
REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS. PAST PERFORMANCE CANNOT GUARANTEE
FUTURE RESULTS. THE CURRENT PERFORMANCE OF THE PORTFOLIO MAY BE LOWER OR HIGHER
THAN THE FIGURES SHOWN. RETURNS AND SHARE PRICE WILL FLUCTUATE, AND REDEMPTION
VALUE MAY BE MORE OR LESS THAN ORIGINAL COST. THE PERFORMANCE RESULTS DO NOT
REFLECT THE DEDUCTION OF TAXES THAT A SHAREHOLDER WOULD PAY ON PORTFOLIO
DISTRIBUTIONS OR THE REDEMPTION OF PORTFOLIO SHARES. PERFORMANCE INCLUDES THE
EFFECT OF DEDUCTING EXPENSES, BUT DOES NOT INCLUDE CHARGES AND EXPENSES
ATTRIBUTABLE TO ANY PARTICULAR VARIABLE CONTRACT OR PLAN. ACCORDINGLY, THE
PROSPECTUS OF THE SPONSORING PARTICIPATING INSURANCE COMPANY SEPARATE ACCOUNT OR
PLAN DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS SHOULD
BE CAREFULLY REVIEWED FOR INFORMATION ON RELEVANT CHARGES AND EXPENSES.
EXCLUDING THESE CHARGES AND EXPENSES FROM QUOTATIONS OF PERFORMANCE HAS THE
EFFECT OF INCREASING THE PERFORMANCE QUOTED, AND THE EFFECT OF THESE CHARGES
SHOULD BE CONSIDERED WHEN COMPARING PERFORMANCE TO THAT OF OTHER MUTUAL FUNDS.
PERFORMANCE INFORMATION CURRENT TO THE MOST RECENT MONTH-END IS AVAILABLE AT

ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
December 31, 2005 (unaudited)

INFORMATION ABOUT YOUR PORTFOLIO'S EXPENSES

      As an investor of the Portfolio, you incur two types of costs: ongoing
expenses and transaction costs. Ongoing expenses include management fees,
distribution and service (12b-1) fees and other Portfolio expenses. Examples of
transaction costs include sales charges (loads), redemption fees and account
maintenance fees, which are not shown in this section and which would result in
higher total expenses. The following table is intended to help you understand
your ongoing expenses of investing in the Portfolio and to help you compare
these expenses with the ongoing expenses of investing in other mutual funds. The
table is based on an investment of $1,000 made at the beginning of the six month
period ended December 31, 2005.

      The table illustrates your Portfolio's expenses in two ways:

      o     ACTUAL PORTFOLIO RETURN. This helps you estimate the actual dollar
            amount of ongoing expenses paid on a $1,000 investment in the
            Portfolio using the Portfolio's actual return during the period. To
            estimate the expenses you paid over the period, simply divide your
            account value by $1,000 (for example, an $8,600 account value
            divided by $1,000 = 8.6), then multiply the result by the number in
            the "Expenses Paid per $1,000" line under the share class you hold.

      o     HYPOTHETICAL 5% PORTFOLIO RETURN. This helps you to compare your
            Portfolio's ongoing expenses with those of other mutual funds using
            the Portfolio's actual expense ratio and a hypothetical rate of
            return of 5% per year before expenses. Examples using a 5%
            hypothetical fund return may be found in the shareholder reports of
            other mutual funds. The hypothetical account values and expenses may
            not be used to estimate the actual ending account balance or
            expenses you paid for the period.

      Please note that the expenses shown in these tables are meant to highlight
your ongoing expenses only and do not reflect any transaction costs, such as
sales charges (loads) or redemption fees. If these transaction costs had been
included, your costs would have been higher. The "Expenses Paid per $1,000" line
of the tables is useful in comparing ongoing expenses only and will not help you
determine the relative total expenses of owning different funds.

ANNUALIZED EXPENSE RATIOS*                                                0.95%

______________

*     EXPENSES ARE EQUAL TO THE PORTFOLIO'S ANNUALIZED EXPENSE RATIO MULTIPLIED
      BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY THE NUMBER OF
      DAYS IN THE MOST RECENT FISCAL HALF YEAR PERIOD, THEN DIVIDED BY 365.

      THE "EXPENSES PAID PER $1,000" AND THE "ANNUALIZED EXPENSE RATIOS" IN THE
      TABLES ARE BASED ON ACTUAL EXPENSES PAID BY THE PORTFOLIO DURING THE
      PERIOD, NET OF FEE WAIVERS AND/OR EXPENSE REIMBURSEMENTS. IF THOSE FEE
      WAIVERS AND/OR EXPENSE REIMBURSEMENTS HAD NOT BEEN IN EFFECT, THE
      PORTFOLIO'S ACTUAL EXPENSES WOULD HAVE BEEN HIGHER. EXPENSES DO NOT
      REFLECT ADDITIONAL CHARGES AND EXPENSES THAT ARE, OR MAY BE, IMPOSED UNDER
      THE VARIABLE CONTRACTS OR PLANS. SUCH CHARGES AND EXPENSES ARE DESCRIBED
      IN THE PROSPECTUS OF THE INSURANCE COMPANY SEPARATE ACCOUNT OR IN THE PLAN
      DOCUMENTS OR OTHER INFORMATIONAL MATERIALS SUPPLIED BY PLAN SPONSORS. THE
      PORTFOLIO'S EXPENSES SHOULD BE CONSIDERED WITH THESE CHARGES AND EXPENSES
      IN EVALUATING THE OVERALL COST OF INVESTING IN THE SEPARATE ACCOUNT.

For more information, please refer to the Portfolio's prospectus.

CREDIT SUISSE TRUST -- BLUE CHIP PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
December 31, 2005
- --------------------------------------------------------------------------------

NOTE 1. ORGANIZATION

      Credit Suisse Trust (the "Trust") is an open-end management investment
company registered under the Investment Company Act of 1940, as amended, and
currently offers eight managed investment portfolios of which one, the Blue Chip
Portfolio (the "Portfolio"), is included in this report. The Portfolio is a
diversified investment fund that seeks long-term capital appreciation. Shares of
the Portfolio are not available directly to individual investors but may be
offered only through (a) variable annuity contracts and variable life insurance
contracts offered by separate accounts of certain insurance companies and (b)
tax-qualified pension and retirement plans. The Portfolio may not be available
in connection with a particular contract or plan. The Trust was organized under
the laws of The Commonwealth of Massachusetts as a business trust on March 15,
1995.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      A) SECURITY VALUATION -- The net asset value of the Portfolio is
determined daily as of the close of regular trading on the New York Stock
Exchange, Inc. (the "Exchange") on each day the Exchange is open for business.
The Portfolio's equity investments are valued at market value, which is
generally determined using the closing price on the exchange or market on which
the security is primarily traded at the time of valuation (the "Valuation
Time"). If no sales are reported, equity investments are generally valued at the
most recent bid quotation as of the Valuation Time or at the lowest asked
quotation in the case of a short sale of securities. Debt securities with a
remaining maturity greater than 60 days are valued in accordance with the price
supplied by a pricing service, which may use a matrix, formula or other
objective method that takes into consideration market indices, yield curves and
other specific adjustments. Debt obligations that will mature in 60 days or less
are valued on the basis of amortized cost, which approximates market value,
unless it is determined that using this method would not represent fair value.
Investments in mutual funds are valued at the mutual fund's closing net asset
value per share on the day of valuation. Securities and other assets for which
market quotations are not readily available, or whose values have been
materially affected by events occurring before the Portfolio's Valuation Time
but after the close of the securities' primary markets, are valued at fair value
as determined in good faith by, or under the direction of, the Board of Trustees
under procedures established by the Board of Trustees. The Portfolio may utilize
a service provided by an independent

                                       18

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

third party which has been approved by the Board of Trustees to fair value
certain securities. When fair-value pricing is employed, the prices of
securities used by a fund to calculate its net asset value may differ from
quoted or published prices for the same securities.

      B) SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions
are accounted for on a trade date basis. Interest income is recorded on the
accrual basis. Dividends are recorded on the ex-dividend date. The cost of
investments sold is determined by use of the specific identification method for
both financial reporting and income tax purposes.

      C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net
investment income and distributions of net realized capital gains, if any, are
declared and paid at least annually. However, to the extent that a net realized
capital gain can be reduced by a capital loss carry- forward, such gain will not
be distributed. Income and capital gain distributions are determined in
accordance with federal income tax regulations, which may differ from accounting
principles generally accepted in the United States of America ("GAAP").

      D) FEDERAL INCOME TAXES -- No provision is made for federal taxes as it is
the Trust's intention to have the Portfolio continue to qualify for and elect
the tax treatment applicable to regulated investment companies under the
Internal Revenue Code of 1986, as amended, and to make the requisite
distributions to its shareholders, which will be sufficient to relieve it from
federal income and excise taxes.

      E) USE OF ESTIMATES -- The preparation of financial statements in
conformity with GAAP 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 revenues and expenses during the reporting period.
Actual results could differ from these estimates.

      F) SHORT-TERM INVESTMENTS -- The Portfolio, together with other
funds/portfolios advised by Credit Suisse Asset Management, LLC ("Credit
Suisse"), an indirect, wholly-owned subsidiary of Credit Suisse Group, pools
available cash into either a short-term variable rate time deposit issued by
State Street Bank and Trust Company ("SSB"), the Portfolio's custodian, or a
money

market fund advised by Credit Suisse. The short-term time deposit issued by SSB
is a variable rate account classified as a short-term investment.

      G) SECURITIES LENDING -- Loans of securities are required at all times to
be secured by collateral at least equal to 102% of the market value of domestic
securities on loan (including any accrued interest thereon) and 105% of the
market value of foreign securities on loan (including any accrued interest
thereon). Cash collateral received by the Portfolio in connection with
securities lending activity may be pooled together with cash collateral for
other funds/portfolios advised by Credit Suisse and may be invested in a variety
of investments, including certain Credit Suisse-advised funds, funds advised by
SSB, the Portfolio's securities lending agent, or money market instruments.
However, in the event of default or bankruptcy by the other party to the
agreement, realization and/or retention of the collateral may be subject to
legal proceedings. The Portfolio had no securities out on loan at December 31,
2005.

      SSB has been engaged by the Portfolio to act as the Portfolio's securities
lending agent. The Portfolio's securities lending arrangement provides that the
Portfolio and SSB will share the net income earned from the securities lending
activities. The Portfolio may also be entitled to certain minimum amounts of
income from its securities lending activities. Securities lending income is
accrued as earned.

NOTE 3. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

      Credit Suisse serves as investment adviser for the Portfolio. For its
investment advisory services, Credit Suisse is entitled to receive a fee from
the Portfolio at an annual rate of 0.50% of the Portfolio's average daily net
assets. Prior to June 1, 2005, Credit Suisse was entitled to receive a fee,
based on the following fee schedule:

      AVERAGE DAILY NET ASSETS                    ANNUAL RATE
      ------------------------                    -----------
         First $100 million            0.75% of average daily net assets
         Over $100 million             0.50% of average daily net assets

      For the year ended December 31, 2005, investment advisory fees earned and
voluntarily waived were $78,822 and $61,177 respectively. Credit Suisse will not
recapture from the Portfolio any fees it waived during the fiscal year ended
December 31, 2005. Fee waivers and reimbursements are voluntary and may be
discontinued by Credit Suisse at any time.

of Credit Suisse, and SSB serve as co-administrators to the Portfolio.

      For its co-administrative services, SSB receives a fee, exclusive of
out-of-pocket expenses, calculated in total for all the Credit Suisse
funds/portfolios co-administered by SSB and allocated based upon relative
average net assets of each fund/portfolio, subject to an annual minimum fee. For
the year ended December 31, 2005, co-administrative services fees earned by SSB
(including out-of-pocket expenses) were $24,508.

      In addition to serving as the Portfolio's co-administrator, CSAMSI
currently serves as distributor of the Portfolio's shares without compensation.

      Merrill Corporation ("Merrill"), an affiliate of Credit Suisse, has been
engaged by the Portfolio to provide certain financial printing and fulfillment
services. For the year ended December 31, 2005, Merrill was paid $3,426 for its
services to the Portfolio.

NOTE 4. LINE OF CREDIT

      The Portfolio, together with other funds/portfolios advised by Credit
Suisse (collectively, the "Participating Funds"), participates in a $75 million
committed, unsecured line of credit facility ("Credit Facility") for temporary
or emergency purposes with Deutsche Bank, A.G. as administrative agent and
syndication agent and SSB as operations agent. Under the terms of the Credit
Facility, the Participating Funds pay an aggregate commitment fee at a rate of

allocated among the Participating Funds in such manner as is determined by the
governing Boards of the Participating Funds. In addition, the Participating
Funds pay interest on borrowings at the Federal Funds rate plus 0.50%. At

      The tax basis of components of distributable earnings differ from the
amounts reflected in the Statement of Assets and Liabilities by temporary
book/tax differences. These differences are primarily due to differing
treatments of losses deferred on wash sales.

      At December 31, 2005, the components of distributable earnings on a tax
basis for the Portfolio were as follows:

      Undistributed net investment income             $     96,044
      Accumulated net realized loss                     (2,545,588)
      Unrealized appreciation                              800,331
                                                      ------------
                                                      $ (1,649,213)
                                                      ============

      At December 31, 2005, the Portfolio had capital loss carryforwards
available to offset possible future capital gains as follows:

                              EXPIRES DECEMBER 31,
                              --------------------
                                      2011
                                   ----------
                                   $2,545,588

      It is uncertain that the Portfolio will realize the full benefit of these
losses prior to expiration.

      During the tax year ended December 31, 2005, the Portfolio utilized
$1,355,607 of the capital loss carryforward.

      At December 31, 2005, the identified cost for federal income tax purposes,
as well as the gross unrealized appreciation from investments for those
securities having an excess of value over cost, gross unrealized depreciation
from investments for those securities having an excess of cost over value and
the net unrealized appreciation from investments were $10,297,342, $1,089,876,
$(289,545) and $800,331, respectively.

NOTE 8. CONTINGENCIES

      In the normal course of business, the Portfolio may provide general
indemnifications pursuant to certain contracts and organizational documents. The
Portfolio's maximum exposure under these arrangements is dependent on future
claims that may be made against the Portfolio and, therefore, cannot be
estimated; however, based on experience, the risk of loss from such claims is
considered remote.

CREDIT SUISSE TRUST -- BLUE CHIP PORTFOLIO
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Board of Trustees of Credit Suisse Trust and Shareholders of
Credit Suisse Trust - Blue Chip Portfolio:

      In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Blue Chip Portfolio (the
"Portfolio"), a portfolio of the Credit Suisse Trust, at December 31, 2005, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended and the financial highlights
for each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Portfolio's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements 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 are free of
material misstatement. An audit 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, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 2005 by
correspondence with the custodian, provide a reasonable basis for our opinion.

CREDIT SUISSE TRUST -- BLUE CHIP PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED)
- --------------------------------------------------------------------------------

      In approving the Advisory Agreement, the Board of Trustees, including the
Independent Trustees, considered the following factors with respect to the Blue
Chip Portfolio (the "Portfolio"):

      INVESTMENT ADVISORY FEE RATES

      The Board reviewed and considered the contractual advisory fee rate of
0.75% on the first $100 million of average daily net assets, declining to 0.50%
on assets in excess of $100 million, for the Portfolio ("Contractual Advisory
Fee"), which was reduced to 0.25% after voluntary fee waivers and/or expense
reimbursements ("Net Advisory Fee"), paid to Credit Suisse Asset Management, LLC
("Credit Suisse") in light of the extent and quality of the advisory services
provided by Credit Suisse. The Board acknowledged that fee waivers and expense
reimbursements could be discontinued at any time. The Board further acknowledged
that effective June 1, 2005, in connection with a change in the Portfolio's
investment strategies to adopt a quantitative approach, the Fund's Contractual
Advisory Fee had been reduced to 0.50% and, as a result of fee waivers and/or
expense reimbursements, the Portfolio's Net Advisory Fee had been reduced to
0.04%. The new fees were not reflected in the information presented to the
Board.

      Additionally, the Board received and considered information comparing the
Portfolio's Contractual Advisory Fee and the Portfolio's overall expenses with
those of funds in both the relevant expense group ("Expense Group") and universe
of funds (the "Expense Universe") provided by Lipper Inc., an independent
provider of investment company data.

      NATURE, EXTENT AND QUALITY OF THE SERVICES UNDER THE ADVISORY AGREEMENT

      The Board received and considered information regarding the nature, extent
and quality of services provided to the Portfolio by Credit Suisse under the
Advisory Agreement. The Board also noted information received at regular
meetings throughout the year related to the services rendered by Credit Suisse.
The Board reviewed background information about Credit Suisse, including its
Form ADV. The Board considered the background and experience of Credit Suisse's
senior management and the expertise of, and the amount of attention given to the
Portfolio by, senior personnel of Credit Suisse. In addition, the Board reviewed
the qualifications, backgrounds and responsibilities of the portfolio management
team primarily responsible for the day-to-day portfolio management of the
Portfolio and the extent of the resources devoted to research and analysis of
actual and potential investments. The Board also received and

CREDIT SUISSE TRUST -- BLUE CHIP PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

considered information about the nature, extent and quality of services and fee
rates offered to other Credit Suisse clients for comparable services.

      PORTFOLIO PERFORMANCE

      The Board received and considered the one-, two- and three-year
performance of the Portfolio, along with comparisons, for all presented periods,
both to the relevant performance group ("Performance Group") and universe of
funds ("Performance Universe") for the Portfolio. The Board was provided with a
description of the methodology used to arrive at the data for the funds included
in the Performance Group and the Performance Universe.

      The Board reviewed information comparing the performance of various Credit
Suisse Funds to performance benchmarks that the Board had previously established
and progress that had been made in certain instances toward achieving those
benchmarks. The Board also reviewed comparisons between the Portfolio and its
identified benchmark over various time periods.

      CREDIT SUISSE PROFITABILITY

      The Board received and considered a profitability analysis of Credit
Suisse based on the fees payable under the Advisory Agreement for the Portfolio,
including other relationships between the Portfolio on the one hand and Credit
Suisse affiliates on the other. The Board received profitability information for
the other funds in the Credit Suisse family of funds.

      ECONOMIES OF SCALE

      The Board considered whether economies of scale in the provision of
services to the Portfolio were being passed along to the shareholders.
Accordingly, the Board considered whether the breakpoints in the Portfolio's fee
structure were appropriate or reasonable taking into consideration economies of
scale or other efficiencies that might accrue from increases in the Portfolio's
asset levels.

      OTHER BENEFITS TO CREDIT SUISSE

      The Board considered other benefits received by Credit Suisse and its
affiliates as a result of their relationship with the Portfolio. Such benefits
include, among others, research arrangements with brokers who execute
transactions on behalf of the Portfolio, administrative and brokerage
relationships with affiliates of Credit Suisse and benefits potentially derived
from an increase in Credit Suisse's businesses as a result of its relationship
with the Portfolio (such as the ability to market to shareholders other
financial products offered by Credit Suisse and its affiliates).

CREDIT SUISSE TRUST -- BLUE CHIP PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      The Board considered the standards applied in seeking best execution,
whether and to what extent soft dollar credits are sought and how any such
credits are utilized, any benefits that may be achieved by using an affiliated
broker and the existence of quality controls applicable to brokerage allocation
procedures. The Board also reviewed Credit Suisse's method for allocating
portfolio investment opportunities among its advisory clients.

      CONCLUSIONS

      In selecting Credit Suisse, and approving the Advisory Agreement and the
investment advisory fee under such agreement, the Board concluded that:

      o     As the Contractual Advisory Fee of 0.50% was the second lowest in
            the Expense Group and its Net Advisory Fee of 0.04% was the lowest
            in the Expense Group, the Portfolio's fees were considered
            reasonable.

      o     The Portfolio's one-year and two-year performance was above the
            median in the Portfolio's Performance Group and higher than the
            Lipper index of comparable funds. In the Performance Universe, the
            Portfolio's one-year performance was above the median and its
            two-year performance was within a reasonable range (within one
            standard deviation) below the median. The Portfolio's three-year
            performance was in a reasonable range (within one standard
            deviation) in both the Performance Group and Performance Universe
            and was higher than the Lipper index of comparable funds. The Board
            noted that it had previously identified the need to address the
            Portfolio's performance, and that Credit Suisse had adopted a
            quantitative approach for the Portfolio and changed portfolio
            managers effective June 1, 2005. The Board noted that the results of
            this change were not fully reflected in the Portfolio's performance
            and that Credit Suisse was in the process of addressing performance
            issues. The Board noted that it would continue to monitor steps
            taken to improve performance.

      o     Aside from performance (as described above), the Board was satisfied
            with the nature and extent of the investment advisory services
            provided to the Portfolio by Credit Suisse and that, based on
            dialogue with management and counsel, the services provided by
            Credit Suisse under the Advisory Agreement is typical of, and
            consistent with, those provided to similar mutual funds by other
            investment advisers. The Board understood that Credit Suisse had or
            was in the process of addressing any performance issues.

                                       27




CREDIT SUISSE TRUST -- BLUE CHIP PORTFOLIO
BOARD APPROVAL OF ADVISORY AGREEMENT (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      o     In light of the costs of providing investment management and other
            services to the Portfolio and Credit Suisse's ongoing commitment to
            the Portfolio, the profits and other ancillary benefits that Credit
            Suisse and its affiliates received were considered reasonable.

      o     Credit Suisse's profitability based on fees payable under the
            Advisory Agreement was reasonable in light of the nature, extent and
            quality of the services provided to the Portfolio thereunder.

      o     In light of the amount of the Net Advisory Fee, the Portfolio's
            current fee structure was considered reasonable.

      No single factor reviewed by the Board was identified by the Board as the
principal factor in determining whether to approve the Advisory Agreement. The
Independent Trustees were advised by separate independent legal counsel
throughout the process.

(e)(1) Pre-Approval Policies and Procedures. The Audit Committee ("Committee")
of the registrant is responsible for pre-approving (i) all audit and permissible
non-audit services to be provided by the independent registered public

delegate its responsibility to pre-approve any such audit and permissible
non-audit services to the Chairperson of the Committee, and the Chairperson
shall report to the Committee, at its next regularly scheduled meeting after the
Chairperson's pre-approval of such services, his or her decision(s). The

pre-approval of such services in accordance with applicable laws, including the
delegation of some or all of the Committee's pre-approval responsibilities to
other persons (other than Credit Suisse or the registrant's officers).
Pre-approval by the Committee of any permissible non-audit services shall not be
required so long as: (i) the aggregate amount of all such permissible non-audit
services provided to the registrant, Credit Suisse and any Covered Services
Provider constitutes not more than 5% of the total amount of revenues paid by
the registrant to its independent registered public accounting firm during the
fiscal year in which the permissible non-audit services are provided; (ii) the
permissible non-audit services were not recognized by the registrant at the time
of the engagement to be non-audit services; and (iii) such services are promptly
brought to the attention of the Committee and approved by the Committee (or its
delegate(s)) prior to the completion of the audit.
