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

                                                               November 22, 2005

Dear Shareholder:

      For the 12 months ended October 31, 2005, Credit Suisse Institutional
Fund, Inc.--Large Cap Value Portfolio 1 (the "Portfolio") had a gain of 12.98%,
vs. an increase of 11.86% for the Russell 1000(R) Value Index. 2

MARKET OVERVIEW: STRONG START BUT LACKLUSTER FINISH

      The period was an overall positive one for the US stock market, though the
upward path was not smooth. Stocks initially surged in the wake of a decisive
Presidential election, but then fell early in 2005 when inflation and
interest-rate worries raised risk thresholds. The market rallied into the
summer, however, aided by benign inflation data and good earnings reports from a
number of visible companies. Hurricane activity and a surge in oil prices caused
the market to weaken again late in the period. The Federal Reserve, meanwhile,
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 October 2005: Third-quarter GDP growth was reported at an annualized rate
of 3.9%, the tenth consecutive quarter of 3% or greater growth.

      From a sector perspective, energy stocks as a group had the best
performance, buoyed by high oil and natural gas prices, while consumer
discretionary stocks were among the underperformers. Value stocks generally
outperformed growth stocks for the 12-month period, in part reflecting the
outperformance of energy stocks, which comprise a larger share of the value
universe.

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 and utilities areas. On the negative side, the
Portfolio's materials holdings struggled, while its producer durables and
technology stocks had positive yet lagging returns for the period.

      In terms of noteworthy recent activity, our purchases included Bank of New
York (1.1% of the net assets as of October 31, 2005), a diversified financial
services company that is nearing completion of a restructuring. We believe that
the stock is undervalued compared with its peers. We also initiated a position
in Kellogg (0.5% of the net assets as of October 31, 2005). We added the food
company after its stock had traded down to attractive valuation levels,

based on our view of the company's compelling fundamentals. Our late-period
eliminations included Smurfit-Stone, a packaging company in the materials
sector. This reflected our concerns regarding the company's pricing power amid
weaker demand for paper products in general.

      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.

CREDIT SUISSE INSTITUTIONAL FUND, INC. -- LARGE CAP VALUE PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
October 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 October 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.

      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.

CREDIT SUISSE INSTITUTIONAL FUND, INC. -- INTERNATIONAL FOCUS PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT
October 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

                                                               November 22, 2005

Dear Shareholder:

      For the 12 months ended October 31, 2005, Credit Suisse Institutional
Fund, Inc.--International Focus Portfolio 1 (the "Portfolio") had a gain of
19.95%, vs. an increase of 20.57% for the Morgan Stanley Capital International
ACWI (All Country World Index) Free Ex-USA Index. 2

MARKET OVERVIEW: GLOBAL GROWTH SUPPORTS BROAD 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.
Most foreign markets outpaced the US, at least in local-currency terms, helped
in part by a more supportive interest rate backdrop. A late-period surge in
Japan's equity market contributed to the outperformance, amid signs that the
world's second-largest economy might be coming back to life. Japan's political
news and the prospects for reforms were supportive as well. Emerging markets as
a group had overall strong returns, with many of these countries benefiting from
high and rising commodity prices.

      From a sector standpoint, returns were broadly positive, with energy,
industrials and materials companies outperforming. The technology and
telecommunications sectors had positive yet lagging returns, reflecting in part
weakness in certain European stocks in these areas. In terms of currency
influences, a rebound in the US dollar vs. the euro and yen in 2005 eroded some
of the gains achieved locally in Europe and Japan for dollar-based investors in
the period.

STRATEGIC REVIEW: AIDED BY STOCK SELECTION IN JAPAN

      The Portfolio modestly underperformed its benchmark for the period. On the
negative side, relatively speaking, the Fund's European holdings as a group
underperformed. Laggards included Royal Bank of Scotland (1.3% of the net assets
as of October 31, 2005), which was hampered in part by acquisition worries, and
Kingfisher (0.3% of the net assets as of October 31, 2005), a UK "do it
yourself" retailer.

      Factors that aided the Portfolio's performance included good stock
selection in Japan. Standouts represented a variety of sectors, including
Komatsu (1.8% of the net assets as of October 31, 2005), a manufacturer of
construction equipment with customers in Japan, the US, and China; and Yamada
Denki (3.0% of the net assets as of October 31, 2005), a retailer of

electronics goods that has improved its competitive position. Other good
performers for the Portfolio included Samsung Heavy (1.1% of the net assets as
of October 31, 2005), a South Korean ship builder with an order book geared to
liquid natural gas (LNG) tankers.

      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 (2.4% of the net assets as of October 31,
2005), based on our view of its valuation and product pipeline. We also
established a position in Novo Nordisk (1.8% of the net assets as of October 31,
2005), a Denmark-based leader in diabetes treatments. Late in 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.

      International investing entails special risk considerations, including
currency fluctuations, lower liquidity, economic and political risks, and
differences in accounting methods. The portfolio's 15 largest holdings may
account for 40% or more of the portfolio's assets. As a result of this strategy,
the portfolio may be subject to greater volatility than a portfolio that invests
in a larger number of issuers.

      In addition to historical information, this report contains
forward-looking statements, which may concern, among other things, domestic and
foreign market, industry and economic trends and developments and government
regulation and their potential impact on the portfolio's investments. These
statements are subject to risks and uncertainties and actual trends,
developments and regulations in the future and their impact on the portfolio
could be materially different from those projected, anticipated or implied. The
portfolio has no obligation to update or revise forward-looking statements.

CREDIT SUISSE INSTITUTIONAL FUND, INC. -- INTERNATIONAL FOCUS PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
October 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 October 31, 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.

      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.

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

                                                               November 22, 2005

Dear Shareholder:

      For the 12 months ended October 31, 2005, Credit Suisse Institutional
Fund, Inc.--Select Equity Portfolio 1 (the "Portfolio") had a gain of 6.48%, vs.
an increase of 8.72% for the Standard & Poor's 500 Index. 2

MARKET OVERVIEW: STRONG START BUT LACKLUSTER FINISH

      The period was an overall positive one for the US stock market, though the
upward path was not smooth. Stocks initially surged in the wake of a decisive
Presidential election, but then fell early in 2005 when inflation and
interest-rate worries raised risk thresholds. The market rallied into the
summer, however, aided by benign inflation data and good earnings reports from a
number of visible companies. Hurricane activity and a surge in oil prices caused
the market to weaken again late in the period. The Federal Reserve, meanwhile,
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 October 2005: Third-quarter GDP growth was reported at an annualized rate
of 3.9%, the tenth consecutive quarter of 3% or greater growth.

      From a sector perspective, energy stocks as a group had the best
performance, buoyed by high oil and natural gas prices, while consumer
discretionary stocks were among the underperformers.

STRATEGIC REVIEW: FOCUS ON COMPANY FUNDAMENTALS

      The Portfolio participated in the market's rally but underperformed its
benchmark. Stocks that hindered the Portfolio's performance included its
consumer discretionary holdings, chiefly certain retail and media companies. The
Portfolio's materials and utilities holdings also underperformed. On the
positive side, the portfolio's technology and energy stocks had good performance
in both absolute and relative terms.

      With respect to noteworthy recent portfolio activity, our purchases
included Alltel (0.9% of the net assets as of October 31, 2005), a telecom
services provider that recently announced a spinoff of a wireline business in
addition to merging with a wireless provider. We believe these moves could
provide investors with a strong wireless pure play in a consolidating industry
with attractive growth forecasts. In the health care area we added WellChoice
(1.1% of the net assets as of October 31, 2005), based on its compelling Blue
Cross business in New York and after recent legislation lowered the company's
political risk in our view.

      Our late-period sales included Textron, an industrials company, based on
escalating raw material costs and weakening end-market demand. We believe these
trends could adversely impact earnings. Another sale was retailer TJX, based on
our concerns over recent weak sales data.

      Going forward, we think stock selection, as opposed to sector allocation,
should prove most critical to performance over the next few months. In this
context, we will continue to seek companies we believe to have good
return-on-invested-capital trends, in a variety of industries. Our focus will
remain on companies that appear committed to creating shareholder value via debt
reduction, higher dividend payments, and/or share repurchase programs, factors
that are often associated with capital-return improvements.

      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 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 information current to the most
recent month-end is available at www.Csam.Com/us.

ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
October 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 October 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 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
of the tables is useful in comparing ongoing expenses only and will not help you
determine the relative total expenses of owning different funds.

CREDIT SUISSE INSTITUTIONAL FUND, INC. -- CAPITAL APPRECIATION PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT
October 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

                                                               November 22, 2005

Dear Shareholder:

      For the 12 months ended October 31, 2005, Credit Suisse Institutional
Fund, Inc.--Capital Appreciation Portfolio 1 (the "Portfolio") had a gain of
8.42%, vs. an increase of 8.81% for the Russell 1000(R) Growth Index. 2

MARKET OVERVIEW: STRONG START BUT LACKLUSTER FINISH

      The period was an overall positive one for the US stock market, though the
upward path was not smooth. Stocks initially surged in the wake of a decisive
Presidential election, but then fell early in 2005 when inflation and
interest-rate worries raised risk thresholds. The market rallied into the
summer, however, aided by benign inflation data and good earnings reports from a
number of visible companies. Hurricane activity and a surge in oil prices caused
the market to weaken again late in the period. The Federal Reserve, meanwhile,
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 October 2005: Third-quarter GDP growth was reported at an annualized rate
of 3.9%, the tenth consecutive quarter of 3% or greater growth.

      From a sector perspective, energy stocks as a group had the best
performance, buoyed by high oil and natural gas prices, while consumer
discretionary stocks were among the underperformers. Value stocks generally
outperformed growth stocks for the 12-month period, in part reflecting the
outperformance of energy stocks, which comprise a larger share of the value
universe.

STRATEGIC REVIEW: FOCUS ON COMPANY FUNDAMENTALS

      The Portfolio had a gain but trailed its benchmark, which we attribute
primarily to underperformance from the Portfolio's consumer discretionary and
financial services stocks. The Portfolio was also underweighted in health-care
services and pharmaceutical stocks, early in the period, when such stocks
outperformed. On the positive side, the Portfolio's materials, consumer staples
and technology holdings had good performance. In addition, the Portfolio had a
small but strong-performing position in the transportation sector during the
period.

      Our noteworthy recent portfolio activity included establishing a position
in Northern Trust (1.3% of the net assets as of October 31, 2005), which we
deemed to be attractively priced relative to its growth prospects, most
particularly within its high-net-worth client business. The company's potential
to benefit

from consolidation activity is also a factor in our view. In the retail area we
added Home Depot (1.8% of the net assets as of October 31, 2005), viewing it as
attractive based on the health of its business and the company's efforts to
control expenses. Our sales included Harrah's Entertainment and Starwood Hotels,
which in our estimation had become fully valued.

      Going forward, we will continue to adhere to our general strategy of
seeking sectors and companies with the 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.

      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 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 information current to the most
recent month-end is available at www.Csam.Com/us.

ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
October 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 October 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.

      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.

CREDIT SUISSE INSTITUTIONAL FUND, INC. -- HARBINGER PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT
October 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

                                                               November 22, 2005

Dear Shareholder:

      For the 12 months ended October 31, 2005, Credit Suisse Institutional
Fund, Inc.--Harbinger Portfolio 1 (the "Portfolio") had a gain of 12.58%, vs. an
increase of 13.83% for the Russell 2500(TM) Growth Index. 2

MARKET OVERVIEW: STRONG START BUT LACKLUSTER FINISH

      The period was an overall positive one for the US stock market, though the
upward path was not smooth. Stocks initially surged in the wake of a decisive
Presidential election, but then fell early in 2005 when inflation and
interest-rate worries raised risk thresholds. The market rallied into the
summer, however, aided by benign inflation data and good earnings reports from a
number of visible companies. Hurricane activity and a surge in oil prices caused
the market to weaken again late in the period. The Federal Reserve, meanwhile,
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 October 2005: Third-quarter GDP growth was reported at an annualized rate
of 3.9%, the tenth consecutive quarter of 3% or greater growth.

      From a sector perspective, energy stocks as a group had the best
performance, buoyed by high oil and natural gas prices, while consumer
discretionary stocks were among the underperformers. Value stocks generally
outperformed growth stocks for the 12-month period, in part reflecting the
outperformance of energy stocks, which comprise a larger share of the value
universe.

STRATEGIC REVIEW: FOCUS ON COMPANY FUNDAMENTALS

      The Portfolio participated in the market's rally but trailed its benchmark
for the period. The Portfolio's health care holdings collectively had a gain yet
underperformed, reflecting a sizable decline posted by Medicines Co., a provider
of pharmaceutical products used in acute hospital care. We opted to eliminate
the position in the period based on our diminished view on its growth prospects.
The Portfolio's materials holdings also contributed negatively to its
performance.

      On the positive side, factors that aided the Portfolio included good stock
selection in the technology sector, where Trident Microsystems Microchip (4.9%
of the net assets as of October 31, 2005) and Genesis Microchip (4.9% of the net
assets as of October 31, 2005) were among the standouts. Both companies provide
graphics manipulation tools used in markets such as video games and

high-definition television. The Portfolio's underweighting in the financial
services sector was also supportive to its relative performance, as the sector
overall had a positive yet lagging return.

      Going forward, we will continue to seek long-term growth of capital by
investing in US companies considered to be in their post-venture-capital stage
of development. We define a post-venture-capital company as one that has
received venture capital financing (within 10 years prior to the Portfolio's
purchase of the company's securities) either during the early stages of the
company's existence, during an early stage of a new product or service, or as
part of a restructuring or recapitalization of the company. Our view is that a
carefully chosen portfolio of such companies has the potential to reward
investors willing to accept heightened short-term volatility over time.

      Because of the nature of the portfolio's post-venture-capital investments
and certain aggressive strategies it may use, an investment in the portfolio may
not be appropriate for all investors.

      In addition to historical information, this report contains
forward-looking statements, which may concern, among other things, domestic and
foreign market, industry and economic trends and developments and government
regulation and their potential impact on the portfolio's investments. These
statements are subject to risks and uncertainties and actual trends,
developments and regulations in the future and their impact on the portfolio
could be materially different from those projected, anticipated or implied. The
portfolio has no obligation to update or revise forward-looking statements.

CREDIT SUISSE INSTITUTIONAL FUND, INC. -- HARBINGER PORTFOLIO
ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
October 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 October 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.

CREDIT SUISSE INSTITUTIONAL FUND, INC. -- INVESTMENT GRADE FIXED INCOME
PORTFOLIO ANNUAL INVESTMENT ADVISER'S REPORT
October 31, 2005 (unaudited)
- --------------------------------------------------------------------------------

                                                               November 22, 2005

Dear Shareholder:

      For the twelve months ended October 31, 2005, the Credit Suisse
Institutional Fund, Inc. - Investment Grade Fixed Income Portfolio 1 (the
"Portfolio") generated a return of 1.38%, versus a same-period gain of 1.13% for
the Lehman Brothers Aggregate Bond Index 2.

MARKET OVERVIEW: ECONOMY GROWS, RATES RISE, CURVE FLATTENS

      The US economy grew at a robust rate of 3.6% throughout the Portfolio's
fiscal year and seemed resilient enough to shrug off the negative effects of
repeated Gulf storms. But sharp increases in prices for commodities such as
gasoline and heating oil, combined with higher interest rates, have gradually
worn down consumer enthusiasm to spend, the force behind much of our economic
recovery. Yet, as signs emerge of a potential economic slowdown, the Federal
Open Market Committee confirmed in its November 1 statement that inflation, not
slower growth, is the greater threat, and that combating the "cumulative rise in
energy and other costs" remains job one.

      In fact, the main driver of the fixed income markets during the
Portfolio's fiscal year was the Fed's measured pace of monetary tightening,
which brought the fed funds rate up 200 basis points, from 1.75% to 3.75%, in
that period. But even as the Fed tightened, the conundrum of lower long-term
rates remains. While yields on the two year Treasury were up 183 basis points
(to 4.38% from 2.55%), the ten year Treasury was up only 52 basis points (to
4.55% from 4.03%), as the spread between them tightened from 147 to a
pencil-thin 18 basis points. This prompted passing fears among market
participants of an inverted curve and that which it has usually tended to
precede: recession.

      In this environment, emerging market debt, boosted by ratings upgrades and
soaring export revenues, outperformed all other fixed income categories,
followed distantly by high yield. Corporate earnings are at record levels,
although stock prices remain range-bound at best. In light of this, company
managements have turned increasingly to share repurchases, dividend increases
and other measures in an effort to boost shareholder value. This shift in
management attention toward shareholders and away from bondholders suggests to
us that the pendular swing in the corporate credit cycle is well underway.

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

STRATEGIC REVIEW: CAUTIOUS POSITIONING IN A RISING RATE ENVIRONMENT

      In the Portfolio we benefited from the rising rate environment through a
curve-flattening trade, underweighting shorter duration securities and
overweighting intermediate duration securities. Otherwise, given our cautious
outlook, we pursued an increasingly conservative investment philosophy as the
year proceeded, building an overweight to cash and increasing our position in
Treasuries over the course of the year relative to the Index.

      After taking gains from our overweight to investment grade credit as well
as several non-benchmark categories (including high yield and emerging market
debt), we moved to an underweight in these sectors. We also reduced our exposure
to Asset Backed Securities and increased our exposure to Commercial Mortgage
Backed Securities, as we saw potential opportunities in commercial real estate.
We remain overweight relative to the Index in both sectors. With regard to
credit, we positioned the Portfolio defensively well in advance of the
threatened downgrade of both General Motors and Ford to junk status, 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. (As of
October 31, 2005, below-investment-grade securities issued by General Motors and
Ford accounted for 0.3% and 1.0% of the net assets, respectively.)

MARKET OUTLOOK: ONWARD AND UPWARD WITH RATES

      Looking ahead, we believe that high energy prices and broad inflation
fears could eventually prove a tax on earnings and a disruption to economic
growth. In addition, fed funds futures are currently pricing in a target rate of
4.25% by year-end, another potential catalyst for market weakness ahead. With
each step in the Federal Reserve's measured pace of monetary tightening, the
market has registered slightly greater risk aversion; low yields and tight
spreads in most spread product only increase the vulnerability to interest rate
risk. Therefore, we will remain cautious on the most interest rate sensitive
securities.

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 October 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.

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

NOTES TO FINANCIAL STATEMENTS
October 31, 2005
- --------------------------------------------------------------------------------

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, 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.
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

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

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 independent third party which has been approved
by the Board of Directors 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) 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").

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      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 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 October 31, 2005, Investment Grade Fixed Income had the following open
forward foreign currency contracts:

      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 October 31, 2005,
Investment Grade Fixed Income had the following open futures contracts:

      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

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

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
according to the contract specifications (days to expiration, current spot index
level, interest rates, dividends, strike price) using the Black-Scholes pricing
model, modified for dividends. The volatility input assumption is interpolated
from the previous day's price. On a weekly basis and at month end, CSAM receives
a price indication sheet from the various broker dealers and inputs these prices
to update the volatility.

      Transactions in written options for puts and calls for the year ended
October 31, 2005 were as follows:

      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.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

      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 year ended October 31, 2005, total
earnings from Large Cap Value, International Focus, Select Equity, Capital
Appreciation, Harbinger and Investment Grade Fixed Income's investment in cash
collateral received in connection with security lending arrangements was
$16,825, $188,430, $5,799, $990, $11,457 and $22,650, respectively, of which
$15,432, $147,084, $5,617, $934, $9,857 and $20,190, respectively, was rebated
to borrowers (brokers). Large Cap Value, International Focus, Select Equity,
Capital Appreciation, Harbinger and Investment Grade Fixed Income retained $978,
$29,044, $128, $40, $1,126, and $1,722 in income, respectively, from the cash
collateral investment and SSB, as lending agent, was paid $415, $12,302, $54,
$16, $474 and $738, 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.

      The tax basis 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, mark to market of forward foreign currency contracts and futures
contracts, and capital losses from fund mergers. At October 31, 2005, the
components of distributable earnings on a tax basis were as follows:

      At October 31, 2005, accumulated undistributed net investment income,
accumulated net realized gain (loss) from investments and paid-in capital have
been adjusted for current period permanent book/tax differences, which arose
principally from differing book/tax treatments of paydowns, gains and losses,
interest accrual on defaulted bonds and forward foreign currency contracts. Net
assets were not affected by these reclassifications:

NOTE 8. 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors of Credit Suisse Institutional Fund, Inc. and
Shareholders of Credit Suisse Institutional Fund, Inc.:

      In our opinion, the accompanying statements of assets and liabilities,
including the schedules 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,
International Focus Portfolio, Select Equity Portfolio, Capital Appreciation
Portfolio, Harbinger Portfolio, and Investment Grade Fixed Income Portfolio
(constituting Credit Suisse Institutional Fund, Inc., hereafter referred to as
the "Fund") at October 31, 2005, the results of each of their operations for the
year then ended, the changes in each of their net assets for each of the two
years in the period then ended and the financial highlights for each of the
years (or periods) presented, 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 Fund'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 October 31, 2005 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

(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
accounting firm to the registrant and (ii) all permissible non-audit services to
be provided by the independent registered public accounting firm to CSAM and any
Covered Services Provider if the engagement relates directly to the operations
and financial reporting of the registrant. The Committee may 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 Committee may also
establish detailed pre-approval policies and procedures for 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 CSAM 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, CSAM 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.

services (other than audit, review or attest services) rendered by PwC to the
