Dear Shareholder:

      For the six months ended April 30, 2005, Credit Suisse Institutional Fund,
Inc.--Large Cap Value Portfolio 1 (the "Portfolio") had a gain of 6.64%, versus
an increase of 6.72% for the Russell 1000(R) Value Index. 2

MARKET OVERVIEW: STRONG START, BUT MOMENTUM FADES

      Stocks surged in the first two months of the period, aided by a concluded
Presidential election that removed a good deal of political uncertainty.
Encouraging employment and inflation data at the time also helped. Market
sentiment turned negative in early March, however, as investors grew cautious
amid signs of economic softening seemingly brought on by high oil prices and
rising short term interest rates. On the earnings front, while first-quarter
2005 results generally met or exceeded expectations, this provided little
support late in the period as the future profit picture dimmed.

      Health care, consumer staples and utilities stocks outperformed as
investors favored relatively defensive sectors. Energy was another good
performer amid high oil prices. Technology stocks and the oil-sensitive
transportation sector were among the poor performers for the period.

STRATEGIC REVIEW: TECHNOLOGY PERFORMS WELL DESPITE OUT-OF-FAVOR SECTOR

      The Portfolio performed roughly in line with its benchmark for the period.
Factors that aided the Portfolio's performance included stock selection in the
financial services, major oil, and transportation sectors. Our exposure within
the last area was largely limited to Burlington Northern (1.3% of the Portfolio
as of April 30, 2005), a railroad company that performed well as
commodity-shipping revenues rose. The Portfolio's technology stocks collectively
had a gain, despite a poor environment for technology stocks generally. The
Portfolio's energy services stocks had lagging results. The Portfolio's consumer
discretionary holdings had negative performance in both absolute and relative
terms.

      In terms of noteworthy recent portfolio activity, our purchases included
Pfizer (1.0% of the Portfolio as of April 30, 2005), which had declined over the
past year on product-pipeline concerns. We believed that a fair amount of
negativity had become priced into the stock, which could be aided going forward
by the company's recently announced cost-cutting program. We also

purchased Office Depot (1.3% of the Portfolio as of April 30, 2005), a retailer
that we believe might be a successful turnaround story under a new CEO. The
company is generating good free cash flows and we see potential for significant
stock repurchases.

      On the sales side, we eliminated our position in Alcoa based in part on
our concerns over the company's input costs. We also sold our position in
Tribune, a newspaper publisher, based on a weaker than expected recovery in
advertising revenues and the related increased competition from internet
companies.

      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 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.

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 April 30, 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.

Dear Shareholder:

      For the six months ended April 30, 2005, Credit Suisse Institutional Fund,
Inc.--International Focus Portfolio 1 (the "Portfolio") had a gain of 8.19%,
versus an increase of 9.14% for the Morgan Stanley Capital International ACWI
(All Country World Index) Free Ex-USA Index. 2

MARKET OVERVIEW: STRONG START, BUT MOMENTUM FADES

      Foreign stock markets began the period on a solid note, aided by a mostly
supportive inflation and interest-rate backdrop and generally good earnings
reports. The rally stalled in early March, however, amid worries that rising US
interest rates and persistently high oil prices would erode global economic
growth. Emerging markets, which were particularly hard hit by rate worries,
nonetheless ended the period with a gain exceeding that of the developed market
group. Within most markets, gains generated locally were even better for
dollar-based investors, as the euro, yen, UK pound and various emerging market
currencies rose against the dollar for the six months as a whole.

      From a sector standpoint, health care, consumer staples and utilities
stocks outperformed as investors favored relatively defensive sectors. Energy
was another good performer amid high oil prices. The technology sector
underperformed, but nonetheless posted a modest gain.

STRATEGIC REVIEW: OUTPERFORMANCE IN ASIA, LATIN AMERICA COUNTERED BY EUROPE

      The Portfolio participated in the rally in foreign stock markets, but it
trailed its benchmark. Good performances from the Portfolio's Asian and Latin
American holdings were countered by underperformance in Europe. This partially
reflected underperformance in the UK, which accounts for about 20% of the
European weighting in the Portfolio's benchmark.

      From a sector standpoint, the Portfolio's consumer staples and financial
services holdings underperformed. In the latter area, laggards included Mega
Financial (a Taiwanese stock that we decided to eliminate from the Portfolio)
and Royal Bank of Scotland (1.7% of the Portfolio as of April 30, 2005), whose
longer-term prospects we nonetheless continue to view favorably. On the positive
side, the Portfolio's telecommunications stocks outperformed, where standouts
included Hellenic Telecom (2.0% of the Portfolio as of April 30, 2005), a
leading provider of fixed-line and wireless telephony services in Greece. The
Portfolio's industrials holdings also were positive contributors, led by Samsung

Heavy (1.0% of the Portfolio as of April 30, 2005), a South Korean ship builder
we purchased late in 2004 in the belief that the stock might benefit from a
pullback in steel prices.

      In terms of noteworthy portfolio adjustments in the period, we scaled back
our exposure to emerging markets based on overall valuations, in the wake of
continued strong performance by the asset class (though we purchased a Brazilian
telecom stock after it sold off sharply in a market downturn). We narrowed our
overweighting in the industrials sector, broadly defined, as certain holdings
became fully valued in our judgment. We remained underweight in the materials
sector, reflecting our belief that there is and will continue to be considerable
excess capacity in areas such as chemicals and steel.

      We were underweighted in the health care sector, where our focus remained
on European pharmaceutical stocks. We narrowed this underweighting, however, as
we believe a fair degree of negative sentiment, regarding issues such as patent
concerns, has been priced into drug stocks. We also see an improving earnings
backdrop for certain companies. We were overweighted in energy through the
period. While we think that there might be an intermediate-term decline in oil
prices based in part on seasonal factors, we believe that spare capacity and
political forces could support a higher-than-expected level for oil prices over
the longer term, and we will attempt to take advantage of pullbacks to
selectively increase our oil exposure.

      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 April 30, 2005.

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

      o   ACTUAL FUND 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% FUND 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.

Dear Shareholder:

      For the six months ended April 30, 2005, Credit Suisse Institutional Fund,
Inc.--Select Equity Portfolio 1 (the "Portfolio") had a gain of 3.93%, versus an
increase of 3.28% for the Standard & Poor's 500 Index. 2

MARKET OVERVIEW: STRONG START, BUT MOMENTUM FADES

      Stocks surged in the first two months of the period, aided by a concluded
Presidential election that removed a good deal of political uncertainty.
Encouraging employment and inflation data at the time also helped. Market
sentiment turned negative in early March, however, as investors grew cautious
amid signs of economic softening seemingly brought on by high oil prices and
rising short term interest rates. On the earnings front, while first-quarter
2005 results generally met or exceeded expectations, this provided little
support late in the period as the future profit picture dimmed.

      Health care, consumer staples and utilities stocks outperformed as
investors favored relatively defensive sectors. Energy was another good
performer amid high oil prices. The technology and consumer discretionary
sectors were poor performers for the period.

STRATEGIC REVIEW: FOCUS ON COMPANY FUNDAMENTALS

      The Portfolio outperformed its benchmark in the period, aided by good
stock selection in the financial services sector and the technology sector,
where our holdings had a gain despite the generally negative environment for
technology stocks. Stock selection in the energy sector was also beneficial, as
was our decision to increase the Portfolio's energy weighting during the period.
On the negative side, relatively speaking, the Portfolio was hindered by stock
selection in the health care sector and by its underweightings in the consumer
staples and utilities areas.

      With respect to noteworthy recent portfolio activity, our purchases
included Boeing (2.1% of the Portfolio as of April 30, 2005), which we think
could benefit from rising commercial aerospace orders, strengthening aircraft
lease rates, and general productivity improvements. We also added Dominion
Resources (1.7% of the Portfolio as of April 30, 2005), a utilities company
whose operating profit could improve going forward, in our view, as unfavorable
oil and gas hedges expire. In addition to generating and distributing energy,
the company has exploration and production activities that could benefit if high
energy prices

persist. Our sales included Alcoa, based on our view that the aluminum company
faces rising input costs along with a potential slowdown in the building
construction and auto production areas.

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 April 30, 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 expense 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

Dear Shareholder:

      For the six months ended April 30, 2005, Credit Suisse Institutional Fund,
Inc.--Capital Appreciation Portfolio 1 (the "Portfolio") had a gain of 1.24%,
versus an increase of 1.15% for the Russell 1000(R) Growth Index. 2

MARKET OVERVIEW: STRONG START, BUT MOMENTUM FADES

      Stocks surged in the first two months of the period, aided by a concluded
Presidential election that removed a good deal of political uncertainty.
Encouraging employment and inflation data at the time also helped. Market
sentiment turned negative in early March, however, as investors grew cautious
amid signs of economic softening seemingly brought on by high oil prices and
rising short term interest rates. On the earnings front, while first-quarter
2005 results generally met or exceeded expectations, this provided little
support late in the period as the future profit picture dimmed.

      Health care, consumer staples and utilities stocks outperformed as
investors favored relatively defensive sectors. Energy was another good
performer amid high oil prices. Technology stocks and the oil-sensitive
transportation sector were among the poor performers for the period.

STRATEGIC REVIEW: ADDING TO PHARMACEUTICALS

      The Portfolio had a gain and outperformed its benchmark. The Portfolio's
technology holdings collectively had a gain, overcoming a weak period for
technology stocks in general. In addition, the Portfolio's transportation
holdings rose within a negative period for the sector. On the negative side,
stock selection in the consumer discretionary sector hindered the Portfolio's
relative performance, with online auction company eBay declining sharply early
in 2005 after a strong showing in 2004. We decided to eliminate the position,
based on the near-term headwinds from eBay's investment spending.

      Our noteworthy recent portfolio activity included purchasing two
pharmaceutical companies. We added Pfizer (1.0% of the Portfolio as of April 30,
2005), a stock that had steadily declined to reach a valuation that we viewed as
attractive relative to the company's growth prospects. We also purchased Wyeth
(1.0% of the Portfolio as of April 30, 2005), which we believe has renewed
growth potential in the wake of surviving numerous product difficulties.

      Elsewhere of note, we established a position in Boeing (1.6% of the
Portfolio as of April 30, 2005), a company we think could benefit from an upturn
in the aerospace cycle. Our late-period sales included EMC Corp., a technology
company focused on data storage systems. The elimination reflected our concerns
over revenue growth within a lackluster technology spending environment. We also
reduced our overall exposure to the industrial sector, in part to increase our
aerospace exposure.

      Going forward, we will continue to adhere to our general strategy of
seeking sectors and companies that we believe have potential to outperform the
overall market. We look for stocks available at a reasonable price relative to
projected growth, while employing themes or patterns associated with growth
companies, such as significant fundamental changes, generation of large free
cash flows or company share-buyback programs.

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 April 30, 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.

                                                                    June 1, 2005

Dear Shareholder:

      For the six months ended April 30, 2005, Credit Suisse Institutional Fund,
Inc.--Harbinger Portfolio 1 (the "Portfolio") had a decline of 0.37%, versus an
increase of 1.13% for the Russell 2500 TM Growth Index. 2

MARKET OVERVIEW: STRONG START, BUT MOMENTUM FADES

      Stocks surged in the first two months of the period, aided by a concluded
Presidential election that removed a good deal of political uncertainty.
Encouraging employment and inflation data at the time also helped. Market
sentiment turned negative in early March, however, as investors grew cautious
amid signs of economic softening seemingly brought on by high oil prices and
rising short term interest rates. On the earnings front, while first-quarter
2005 results generally met or exceeded expectations, this provided little
support late in the period as the future profit picture dimmed. The uncertainty
especially weighed on aggressive growth stocks.

      Health care, consumer staples and utilities stocks generally outperformed
as investors favored relatively defensive sectors. The energy sector was a
strong performer amid high oil prices. Technology stocks and the oil-sensitive
transportation sector were among the poor performers for the period.

STRATEGIC REVIEW: FOCUS ON COMPANY FUNDAMENTALS

      The Portfolio's decline and underperformance of its benchmark is
attributable to stock selection in the materials sector, specifically its
position in GrafTech (2.5% of the Portfolio as of April 30, 2005). The stock
declined sharply on revenue and earnings disappointments, despite the company's
exposure to steel (its products are used in the manufacture of steel), a
commodity whose price has soared over the past two years. We opted to eliminate
this position recently, based on our concerns over the company's management of
pricing contracts.

      On the positive side, the Portfolio's technology holdings collectively had
a gain, despite the generally negative environment for technology stocks in the
period. Standouts included Macromedia (6.2% of the Portfolio as of April 30,
2005), which rallied on news that the company, which provides web-publishing
products, would be acquired by Adobe. The Portfolio's consumer discretionary
holdings also performed well, paced by Activision (2.6% of the Portfolio as of
April 30, 2005) in the entertainment software area.

      Recent market weakness notwithstanding, we remain very stock specific in
our focus and believe we can continue to find companies that we feel can benefit
over the longer term from themes such as the growth of internet advertising.
Another area that we think presents opportunity is specialized semiconductor
companies, and we continue to look for names that are compelling. Health care
services is another theme in the portfolio, including companies with exposure to
Medicaid services. Finally, we continue to believe that the lodging industry
could benefit from rising levels of consumer and business travel in 2005.

Dear Shareholder:

      For the six months ended April 30, 2005, Credit Suisse Institutional Fund,
Inc-Investment Grade Fixed Income Portfolio 1 (the "Portfolio") generated a
return of 1.35%, versus a same period gain of 0.98% for the Lehman Brothers
Aggregate Bond Index. 2

MARKET OVERVIEW: A SHIFT IN THE CYCLE

      The major factor driving activity in the period was the Federal Open
Market Committee's graduated approach to monetary tightening, which brought the
fed funds rate up 100 basis points, from 1.75% to 2.75% during the Portfolio's
fiscal half-year. In support of these measured rate hikes the central bank cited
continued improvement in labor-market conditions and growth in total output,
alongside balanced inflation risks. The upward trend in crude oil prices, which
reached a new high of $58 per barrel in March, contributed merely to a
transitory soft patch in economic growth. While short-term interest rates tended
to follow the Fed higher, rates on the long end strangely declined, due in our
view to strong foreign demand for US assets of longer duration. This resulted in
a significant flattening of the yield curve, as the spread between 2-year and
10-year Treasuries dropped from 150 to 55 basis points.

      Fed Chairman Greenspan termed the unusual yield curve phenomenon a
conundrum, but we believe the real mystery was the lack of risk aversion among
bond market participants. The longstanding hunger for yield in bonds remained
avid into the new year, particularly for lower rated investment grade and high
yield corporate credits whose valuations had reached historic highs. The
correction finally came in mid-March in a sell-off triggered by a General Motors
(GM) earnings warning, as a new risk-premium got priced into the market. In our
view, the GM news helped to accelerate a long-awaited shift in the credit cycle,
as we begin to witness increasingly shareholder-friendly action among
corporations such as buy-backs and increased dividends.

STRATEGIC REVIEW: DURATION TRADES AND SECURITY SELECTION

      In the Portfolio we took advantage of the Fed's measured rate hikes
through a curve flattening trade, underweighting shorter duration securities and

                                       32

overweighting intermediate duration securities. With regard to the credit
sector, we positioned the Portfolio defensively well in advance of the GM
earnings warning, reducing our exposure to lower quality investment grade
issuers and any credits we believe likely to be impacted by the implosion in the
automotive sector. Our positions in Mortgage Backed Securities (MBS) benefited
due to low volatility and an emphasis on selected mortgage pools with lower
probability of refinancing. In addition, we maintained exposure to select
emerging market bonds, which added to our outperformance for the period.
Negative contributions to performance included our underweight allocation to US
Agencies, which strengthened in spite of the continuing turbulence at Fannie
Mae.

MARKET OUTLOOK: FUNDAMENTALLY SOUND

      In spite of the difficult environment among spread product in the latter
part of the fiscal half-year, we believe the credit environment remains
fundamentally sound thanks to moderate increases in corporate profitability and
the continuing build-up of cash on corporate balance sheets. Given our positive
outlook on credit fundamentals, we would view any further widening in corporate
spreads as an opportunity to increase our weighting relative to the index.

SEMIANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
April 30, 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 April 30, 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 RATIO" 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.

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

1     For the period May 1, 2002 (inception date) through October 31, 2002.

2     As required, effective November 1, 2001, the Portfolio adopted the
      provisions of AICPA Audit and Accounting Guide for Investment Companies
      and began including paydown gains and losses in interest income. The
      effect of this change is less than $0.01 per share for the year ended

      gains and losses and the ratio of net investment income to average net
      assets.

NOTE 1. ORGANIZATION

      The Credit Suisse Institutional Fund, Inc. (the "Fund") is registered
under the Investment Company Act of 1940, as amended, as an open-end management
investment company and currently offers six managed investment funds. The Large
Cap Value Portfolio ("Large Cap Value"), the International Focus Portfolio
("International Focus"), the Capital Appreciation Portfolio ("Capital
Appreciation"), the Select Equity Portfolio ("Select Equity"), and the
Investment Grade Fixed Income Portfolio ("Investment Grade Fixed Income") are
each classified as diversified and the Harbinger Portfolio ("Harbinger") is
classified as non-diversified (each a "Portfolio" and collectively, the
"Portfolios"). The Fund was incorporated under the laws of the State of Maryland
on May 14, 1992.

      Investment objectives for each Portfolio are as follows: Large Cap Value
and Investment Grade Fixed Income seek total return; Capital Appreciation,
International Focus and Select Equity seek long-term capital appreciation;
Harbinger seeks long-term growth of capital.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      A) SECURITY VALUATION -- The net asset value of each 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.
Each 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.
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 Directors under procedures established by
the Board of Directors. The Portfolios may utilize a service provided by an

                                       76

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

independent third party which has been approved by the Board of Directors to
fair value certain securities.

      B) FOREIGN CURRENCY TRANSACTIONS -- The books and records of the
Portfolios 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 Portfolios do 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 Portfolios isolate 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 for Large Cap Value, Capital Appreciation,
International Focus, Select Equity and Harbinger. Dividends from net investment
income are declared daily and paid monthly for Investment Grade Fixed Income.
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
each Portfolio's intention to 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

                                       77

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

      H) FORWARD FOREIGN CURRENCY CONTRACTS -- Each 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. Each 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 April 30, 2005, Investment Grade Fixed Income had the following open
forward foreign currency contracts:

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      I) TBA PURCHASE COMMITMENTS -- Each Portfolio may enter into "TBA" (to be
announced) purchase commitments to purchase securities for a fixed price at a
future date, typically not exceeding 45 days. TBA purchase commitments may be
considered securities in themselves, and involve a risk of loss if the value of
the security to be purchased declines prior to settlement date. This risk is in
addition to the risk of decline in each Portfolio's other assets. Unsettled TBA
purchase commitments are valued at the current market value of the underlying
securities, according to the procedures described under "Security Valuation"
above.

      J) FUTURES -- Each Portfolio may enter into futures contracts to the
extent permitted by its investment policies and objectives. Upon entering into a
futures contract, each Portfolio is required to deposit cash or pledge U.S.
Government securities as initial margin. Subsequent payments, which are
dependent on the daily fluctuations in the value of the underlying instrument,
are made or received by the Portfolio each day (daily variation margin) and are
recorded as unrealized gains or losses until the contracts are closed.

      When the contracts are closed, the Portfolio records a realized gain or
loss equal to the difference between the proceeds from (or cost of) the closing
transactions and the Portfolio's basis in the contract. Risks of entering into
futures contracts for hedging purposes include the possibility that a change in
the value of the contract may not correlate with the changes in the value of the
underlying instruments. In addition, the purchase of a futures contract involves
the risk that the Portfolio could lose more than the original margin deposit and
subsequent payments required for a futures transaction. At April 30, 2005,
Investment Grade Fixed Income had the following open futures contracts:




                                                                                      UNREALIZED

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      K) OPTIONS -- Investment Grade Fixed Income may purchase and write (sell)
call and put options on securities, currencies and swap agreements (options on
swap agreements are commonly known as "swaptions"). The Portfolio may write
covered and uncovered put and call options and purchase put and call options for
hedging purposes or to increase total return. The risk associated with
purchasing an option is that the Portfolio pays a premium whether or not the
option is exercised. Additionally, the Portfolio bears the risk of loss of
premium and change in market value should the counterparty not perform under the
contract. Put and call options purchased are accounted for in the same manner as
portfolio securities. The cost of securities acquired through the exercise of
call options is increased by the premium paid. The proceeds from securities sold
through the exercise of put options are decreased by the premium paid.

      When the Portfolio writes an option, the premium received by the Portfolio
is recorded as a liability and is subsequently adjusted to the current market
value of the option written. Premiums received from writing options that expire
unexercised are recorded by the Portfolio on the expiration date as realized
gains from options transactions. The difference between the premium received and
the amount paid on effecting a closing purchase transaction, including brokerage
commissions, is also treated as a realized gain, or if the premium received is
less than the amount paid for the closing purchase transaction, as a realized
loss. If a call option is exercised, the premium received is added to the
proceeds from the sale of the underlying security in determining whether the
Portfolio has realized a gain or loss. If a put option is exercised, the premium
received reduces the cost basis of the security purchased by the Portfolio. The
risk involved in writing an option is that, if the option is exercised, the
underlying security could then be purchased or sold by the Portfolio at a
disadvantageous price. Uncovered options are riskier than covered options
because there is no underlying security held by the Portfolio that can act as a
partial hedge. Uncovered calls have speculative characteristics and the
potential for loss is unlimited. There is also a risk that the securities on
which the option is written may not be available for purchase if the call option
is exercised. Uncovered put options have speculative characteristics and the
potential loss is substantial.

      Exchange-traded options are valued at the last sale price in the market
where such contracts are principally traded. OTC equity/index options are priced

      L) 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 each Portfolio in connection with
securities lending activity may be pooled together with cash collateral for
other funds/portfolios advised by CSAM and may be invested in a variety of
investments, including certain CSAM-advised funds, funds advised by SSB, the
Portfolios' 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 Portfolios to act as the Portfolios'
securities lending agent. The Portfolios' securities lending arrangement
provides that the Portfolios and SSB will share the net income earned from
securities lending activities. During the six months ended April 30, 2005, total
earnings from Large Cap Value, International Focus, Select Equity, Harbinger and
Investment Grade Fixed Income's investment in cash collateral received in
connection with securities lending arrangements was $4,330, $55,130, $4,313,
$6,644, and $4,480, respectively, of which $3,800, $42,483, $4,152, $5,745, and
$4,165, respectively, was rebated to borrowers (brokers). Large Cap Value,
International Focus, Select Equity, Harbinger and Investment Grade Fixed Income
retained $372, $8,702, $113, $634, and $222, respectively, from the cash
collateral investment

and SSB, as lending agent, was paid $158, $3,945, $48, $265, and $93,
respectively. The Portfolios may also be entitled to certain minimum amounts of
income from their securities lending activities. Securities lending income is
accrued as earned.

      M) OTHER -- The Portfolios 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 risks
(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 Portfolios may be subject to taxes imposed by countries in which they
invest, with respect to their 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 Portfolios
accrue such taxes when the related income or gains are earned.

      Each Portfolio may invest up to 15% (except International Focus, which may
invest up to 10%) 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.

advisory services, CSAM is entitled to receive a fee from each Portfolio based

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

NOTE 7. CONTINGENCIES

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

CREDIT SUISSE INSTITUTIONAL FUND, INC.
BOARD APPROVAL OF ADVISORY AGREEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

      In approving the Advisory Agreements and Sub-Advisory Agreements, the
Board of Directors of the Fund, including the Independent Directors, considered
the following factors with respect to the Fund:

      INVESTMENT ADVISORY FEE RATE

      The Board reviewed and considered the contractual advisory fee rates of
0.75%, 0.50%, 0.50% 0.30%, 1.00% and 0.80% paid by the Large Cap Value
Portfolio, Select Equity Portfolio, Capital Appreciation Portfolio, Investment
Grade Fixed Income Portfolio, Harbinger Portfolio and the International Focus
Portfolio, respectively (the "Contractual Advisory Fee") to CSAM in light of the
extent and quality of the advisory services provided. The Board also reviewed
and considered the fee waivers and/or expense reimbursement arrangements
currently in place and considered the actual fee rates after taking waivers and
reimbursements into account of 0.18%, 0.00%, 0.00%, 0.00%, 0.00% and 0.58%, for
the Large Cap Value Portfolio, Select Equity Portfolio, Capital Appreciation
Portfolio, Investment Grade Fixed Income Portfolio, Harbinger Portfolio and the
International Focus Portfolio, respectively, (the "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 each
Portfolio's Contractual Advisory Fees and Net Advisory Fees and their overall
expenses with those of funds in both the relevant expense group ("Peer Group")
and universe of funds (the "Universe") provided by 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 each Portfolio by CSAM under the Advisory
Agreements with respect to that portfolio. The Board also noted information
received at regular meetings throughout the year related to the services
rendered by CSAM. The Board reviewed background information about CSAM,
including its Form ADV and its record of compliance with the federal securities
law. The Board considered the background and experience of CSAM's senior
management and the expertise of, and the amount of attention given to the
Portfolios by, both junior and senior personnel of CSAM. In addition, the Board
reviewed the qualifications, backgrounds and responsibilities of the portfolio
management teams primarily responsible for the day-to-day portfolio management
of the Portfolios and the extent of the resources devoted to research and
analysis of actual and potential investments.

                                       88




CREDIT SUISSE INSTITUTIONAL FUND, INC.
BOARD APPROVAL OF ADVISORY AGREEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

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

      PORTFOLIO PERFORMANCE
      ---------------------

      The Board received and considered the one and two-year performance of each
Portfolio, along with comparisons, for all presented periods, both to the Peer
Group and the Universe. The Board was provided with a description of the
methodology used to arrive at the funds included in the Peer Group and the
Universe.

      The Board reviewed information comparing the performance of the 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 each
Portfolio and its identified benchmark over various time periods.

      CSAM PROFITABILITY
      ------------------

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

      ECONOMIES OF SCALE
      ------------------

      The Board considered whether economies of scale in the provision of
services to each Portfolio was 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 Portfolios' asset levels.

      OTHER BENEFITS TO CSAM
      ----------------------

      The Board considered other benefits received by CSAM and its affiliates as
a result of their relationship with each Portfolio. Such benefits include, among
others, research arrangements with brokers who execute transactions on behalf of
the Portfolios, administrative and brokerage relationships with affiliates of
CSAM and benefits potentially derived from an increase in CSAM's business as

                                       89




CREDIT SUISSE INSTITUTIONAL FUND, INC.
BOARD APPROVAL OF ADVISORY AGREEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

a result of their relationship with the Portfolios (such as the ability to
market to shareholders other financial products offered by CSAM 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 CSAM's method for allocating portfolio
investment opportunities among the Portfolios and other advisory clients.

      CONCLUSIONS
      -----------

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

      LARGE CAP VALUE

      o   although the Contractual Advisory Fee was higher than the median of
          its Peer Group, the fee was considered reasonable recognizing that the
          amount that shareholders were actually charged, the Net Advisory Fee,
          was lower than median of its Peer Group.

      o   although the Portfolio's three and five-year performance lagged that
          of its Peer Group, which the Board discussed with CSAM, the Board
          noted that the Portfolio's performance had shown improvement and its
          one-year performance was better than the median of its Peer Group.

      SELECT EQUITY

      o   the Contractual Advisory Fee was the lowest of its Peer Group and the
          fee was considered reasonable.

      o   the Portfolio's one and two-year performance lagged that of its Peer
          Group. The Board discussed the underperformance with CSAM and CSAM
          subsequently advised the Board that changes in the methodology for
          managing the Portfolio are under review in order to address
          underperformance.

      CAPITAL APPRECIATION

      o   the Contractual Advisory Fee was lower than the median of its Peer
          Group and the fee was considered reasonable.

      o   the Portfolio's one and two-year performance lagged that of its Peer
          Group. The Board discussed the underperformance with CSAM, but

CREDIT SUISSE INSTITUTIONAL FUND, INC.
BOARD APPROVAL OF ADVISORY AGREEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

          considered the enhanced research and investment changes that have been
          instituted by CSAM to address underperformance.

      INVESTMENT GRADE FIXED INCOME

      o   the fee was considerable reasonable since the Contractual Advisory Fee
          was lower than the median of its Peer Group and the Net Advisory Fee
          was the lowest of its Peer Group.

      o   recognizing that the Portfolio's one and two-year performance lagged
          that of its Peer Group, the Board discussed the matter with CSAM. CSAM
          advised the Board that it had implemented enhanced research and
          investment changes in order to address underperformance.

      HARBINGER

      o   although the Contractual Advisory Fee was higher than the median of
          its Peer Group, the fee was considered reasonable recognizing that the
          amount that shareholders were actually charged, the Net Advisory Fee,
          was lower than median of its Peer Group.

      o   although the Portfolio's one-year performance lagged that of its Peer
          Group, which the Board discussed with CSAM, CSAM advised the Board
          that changes in the methodology for managing the Portfolio are under
          review in order to address underperformance.

      INTERNATIONAL FOCUS

      o   the Contractual Advisory Fee and Net Advisory Fee were each lower than
          the median of its Peer Group and the fee was considered reasonable.

      o   the Portfolio's three and five-year performance were within a
          reasonable range around the median of its Peer Group. Nevertheless,
          the Board directed CSAM to suggest a means to improve performance.
          CSAM subsequently advised the Board that changes in the Portfolio are
          under review to address underperformance.

      ALL PORTFOLIOS

      o   aside from performance (as described above), the Board was satisfied
          with the nature and extent of the investment advisory services
          provided to each Portfolio by CSAM and that, based on dialogue with
          management and counsel, the services provided by CSAM under the
          Advisory Agreements are typical of, and consistent with, those
          provided to mutual funds by

                                       91

          other investment advisers. The Board understood that CSAM 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 each Portfolio and CSAM's ongoing commitment to each
          Portfolio and willingness to cap fees and expenses, the profits and
          other ancillary benefits that CSAM and its affiliates received were
          considered reasonable.

      o   CSAM'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 each Portfolio thereunder.

      o   in light of (the relatively small size of the Portfolios and) the
          amount of the Net Advisory Fees, each 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 with
respect to each Portfolio. The Independent Directors were advised by separate
independent legal counsel throughout the process.
