The period was a volatile, though ultimately positive, one for equity markets around the world. Stocks initially rose, continuing a rally begun in March 2003 on hopes that a reviving U.S. economy would support growth globally. Markets finished the period on a weak note, however, hurt by fears of rising U.S. interest rates, worries that China's strong growth would be reined in (China has been a source of growth for a number of markets in Asia and elsewhere), and renewed geopolitical concerns. The Portfolio trailed its benchmark, in part due to underperformance of its Japan holdings. Selected via our bottom-up investment process, these holdings are what we consider to be higher-quality stocks representing companies with above average earnings potential. However, such stocks performed poorly in the period as a whole, in many instances for technical reasons (such as cross shareholding and pension-related selling overhangs). That notwithstanding, we believe our companies in Japan have good long-term prospects. The Portfolio's European holdings modestly underperformed as a group. On the positive side, the Portfolio's telecommunications holdings (especially within Latin America), aided its performance, as did its materials and energy holdings in general. In terms of noteworthy recent portfolio activity, one move we made was to increase our exposure to the energy area. We ended the period roughly neutrally weighted here, after being underweighted through much of 2003. Our decision to add was based on relative valuations -- energy stocks underperformed last year - -- combined with our more bullish outlook on energy prices. We believe that OPEC is determined to support relatively high oil prices, with firmer oil revenues needed to address local social concerns. Elsewhere, we selectively added some technology stocks, taking advantage of market pullbacks. Our view is that earnings could actually be quite strong in certain areas of technology as the year progresses. Our goal was to purchase these stocks prior to any positive earnings surprises that may be announced. In the consumer area, we purchased shares of a U.K. tobacco company that we feel is attractively valued, offers a relatively high dividend yield, and does not present the litigation risk associated with U.S. tobacco companies. We reduced 1 <Page> our exposure to the materials and consumer discretionary sectors as individual stocks began to reach our price targets. Late in the period we eliminated our direct exposure to China. Our view is that investor sentiment is tending toward a hard landing scenario for the Chinese economy, and that the market will likely be quite vulnerable to any disappointing data in the intermediate term. We also started to narrow our underweighting in the European pharmaceutical industry, where we think the risk/reward profile has improved. Looking ahead, we believe that the quality and consistency of earnings will likely be drivers of stock performance this year. In that context, we will continue to adhere to our discipline, focusing on what we deem to be profitable companies with sustainable earnings growth potential.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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 eight managed investment funds, one of which, the International Focus Portfolio (the "Portfolio"), is contained in this report. The Portfolio is classified as diversified and has long-term capital appreciation as its investment objective. The Fund was incorporated under the laws of the State of Maryland on May 14, 1992. Effective as of the close of business on August 22, 2003, the Portfolio acquired all of the net assets of Credit Suisse Institutional International Fund ("International Fund") in a tax-free exchange of shares. The Portfolio was also the accounting survivor in the tax-free exchange. The shares exchanged were 12,106,921 shares (valued at $100,609,127) of the Portfolio for 10,766,487 shares of International Fund. The International Fund's net assets of $100,609,127 at that date, which included $13,928,022 of unrealized appreciation, were combined with those of the Portfolio. The aggregate net assets of International Fund and the Portfolio immediately before the acquisition were $100,609,127 and $50,947,690, respectively, and the combined net assets of the Portfolio after the acquisition were $151,556,817. A) SECURITY VALUATION -- The net asset value of the Portfolio is determined daily as of the close of regular trading on the New York Stock Exchange, Inc. (the "Exchange") on each day the Exchange is open for business. The Portfolio's equity investments are valued at market value, which is generally determined using the closing price on the exchange or market on which the security is primarily traded at the time of valuation (the "Valuation Time"). If no sales are reported, equity investments are generally valued at the most recent bid quotation as of the Valuation Time or at the lowest asked quotation in the case of a short sale of securities. Debt securities with a remaining maturity greater than 60 days are valued in accordance with the price supplied by a pricing service, which may use a matrix, formula or other objective method that takes into consideration market indices, yield curves and other specific adjustments. Debt obligations that will mature in 60 days or less are valued on the basis of amortized cost, which approximates market value, unless it is determined that this method would not represent fair value. 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 Portfolio may utilize a service provided by an 13 <Page> independent third party which has been approved by the Board of Directors to fair value certain portfolio securities. B) FOREIGN CURRENCY TRANSACTIONS -- The books and records of the Portfolio are maintained in U.S. dollars. Transactions denominated in foreign currencies are recorded at the current prevailing exchange rates. All assets and liabilities denominated in foreign currencies are translated into U.S. dollar amounts at the current exchange rate at the end of the period. Translation gains or losses resulting from changes in the exchange rate during the reporting period and realized gains and losses on the settlement of foreign currency transactions are reported in the results of operations for the current period. The Portfolio does not isolate that portion of realized gains and losses on investments in equity securities which is due to changes in the foreign exchange rate from that which is due to changes in market prices of equity securities. The Portfolio isolates that portion of realized gains and losses on investments in debt securities which is due to changes in the foreign exchange rate from that which is due to changes in market prices of debt securities. C) SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions are accounted for on a trade date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. The cost of investments sold is determined by use of the specific identification method for both financial reporting and income tax purposes. D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net investment income and distributions of net realized capital gains, if any, are declared and paid at least annually. However, to the extent that a net realized capital gain can be reduced by a capital loss carryover, such gain will not be distributed. Income and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America ("GAAP"). E) FEDERAL INCOME TAXES -- No provision is made for federal taxes as it is the Fund's intention to have the Portfolio continue to qualify for and elect the tax treatment applicable to regulated investment companies under the Internal Revenue Code of 1986, as amended, and 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 14 <Page> disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. G) SHORT-TERM INVESTMENTS -- The Portfolio, together with other funds/portfolios advised by Credit Suisse Asset Management, LLC ("CSAM"), an indirect, wholly-owned subsidiary of Credit Suisse Group, pools available cash into either a short-term variable rate time deposit issued by State Street Bank and Trust Company ("SSB"), the Portfolio's custodian, or a money market fund advised by 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 -- The Portfolio may enter into forward foreign currency contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency. The Portfolio will enter into forward foreign currency contracts primarily for hedging purposes. Forward foreign currency contracts are adjusted by the daily 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, 2004, the Portfolio had no open forward foreign currency contracts. I) SECURITIES LENDING -- Loans of securities are required at all times to be secured by collateral at least equal to 102% of the market value of domestic securities on loan (including any accrued interest thereon) and 105% of the market value of foreign securities on loan (including any accrued interest thereon). Cash collateral received by the Portfolio in connection with securities lending activity is 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 Portfolio's securities lending agent or money market instruments. However, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. 15 <Page> The market value of securities on loan to brokers and the value of collateral held by the Portfolio with respect to such loans at April 30, 2004 is as follows: <Table> <Caption> MARKET VALUE OF VALUE OF SECURITIES LOANED COLLATERAL RECEIVED ----------------- ------------------- $ 34,990,901 $ 36,841,138 </Table> Prior to March 17, 2004, Credit Suisse First Boston ("CSFB"), an affiliate of CSAM, had been engaged by the Portfolio to act as the Portfolio's securities lending agent. Effective March 17, 2004, SSB has been engaged by the Portfolio to act as the Portfolio's securities lending agent. The Portfolio's securities lending arrangement provides that the Portfolio and SSB will share the net income earned from securities lending activities, with the Portfolio receiving 70% and SSB receiving 30% of the earnings from the investment of cash collateral or any other securities lending income in accordance with the provisions of the securities lending agency agreement. Securities lending income is accrued as earned. J) OTHER -- The Portfolio may invest in securities of foreign countries and governments which involve certain risks in addition to those inherent in domestic investments. Such risks generally include, among others, currency risk (fluctuations in currency exchange rates), information risk (key information may be inaccurate or unavailable) and political risk (expropriation, nationalization or the imposition of capital or currency controls or punitive taxes). Other risks of investing in foreign securities include liquidity and valuation risks. The Portfolio may be subject to taxes imposed by countries in which it invests, with respect to its investments in issuers existing or operating in such countries. Such taxes are generally based on income earned or repatriated and capital gains realized on the sale of such investments. The Portfolio accrues such taxes when the related income or gains are earned. The Portfolio may invest up to 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. 16 <Page> NOTE 2. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES CSAM serves as investment adviser for the Portfolio. For its investment advisory services, CSAM is entitled to receive a fee from the Portfolio at an annual rate of 0.80% of the Portfolio's average daily net assets.

Merrill Corporation ("Merrill"), an affiliate of CSAM, has been engaged by the Portfolio to provide certain financial printing and fulfillment services. For six months ended April 30, 2004, Merrill was paid $6,780 for its services to the Portfolio. 17 <Page> NOTE 3. LINE OF CREDIT The Portfolio, together with other funds/portfolios advised by CSAM (collectively, the "Participating Funds"), participates in a $75 million committed, unsecured line of credit facility ("Credit Facility") for temporary or emergency purposes with Deutsche Bank, A.G. as administrative agent and syndication agent and SSB as operations agent. Under the terms of the Credit Facility, the Participating Funds pay an aggregate commitment fee at a rate of 0.10% per annum on the average unused amount of the Credit Facility, which is allocated among the Participating Funds in such manner as is determined by the governing Boards of the Participating Funds. In addition, the Participating Funds pay interest on borrowings at the Federal Funds rate plus 0.50%. At April 30, 2004 the Portfolio had no loans outstanding under the Credit Facility. During the six months ended April 30, 2004, the Portfolio had borrowings under the Credit Facility as follows: <Table> <Caption> AVERAGE DAILY WEIGHTED AVERAGE MAXIMUM DAILY LOAN BALANCE INTEREST RATE % LOAN OUTSTANDING ------------- ---------------- ---------------- $ 5,421,000 1.549% $ 8,671,000 </Table> NOTE 4. PURCHASES AND SALES OF SECURITIES For the six months ended April 30, 2004, purchases and sales of investment securities (excluding short-term investments) were $87,017,731 and $114,769,114, respectively. At April 30, 2004, the identified cost for federal income tax purposes, as well as the gross unrealized appreciation from investments for those securities having an excess of value over cost, gross unrealized depreciation from investments for those securities having an excess of cost over value and the net unrealized appreciation from investments were $164,460,433, $20,898,949, $(2,972,082) and $17,926,867, respectively. NOTE 5. CAPITAL SHARE TRANSACTIONS The Fund is authorized to issue up to sixteen billion full and fractional shares of common stock of separate series having a $.001 par value per share. Shares of eight series have been classified, one of which constitutes the 18 <Page> interest in the Portfolio. Transactions in capital shares of the Portfolio were as follows: <Table> <Caption> FOR THE SIX MONTHS ENDED FOR THE YEAR ENDED APRIL 30, 2004 (UNAUDITED) OCTOBER 31, 2003 -------------------------- ------------------ Shares sold 1,112,572 14,590,640 Shares exchanged due to merger -- 12,106,921 Shares issued in reinvestment of dividends and distributions 4,833,577 40,891 Shares redeemed (24,503,688) (14,776,756) ------------ ------------ Net increase (decrease) (18,557,539) 11,961,696 ============ ============ </Table> On April 30, 2004, the number of shareholders that held 5% or more of the outstanding shares of the Portfolio were as follows: <Table> <Caption> NUMBER OF APPROXIMATE PERCENTAGE SHAREHOLDERS OF OUTSTANDING SHARES ------------ ----------------------- 5 80% </Table> Some of the shareholders are omnibus accounts, which hold shares on behalf of individual shareholders. NOTE 6. CONTINGENCIES In the normal course of business, the Portfolio may provide general indemnifications pursuant to certain contracts and organizational documents. The Portfolio's maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated; however, based on experience, the risk of loss from such claims is considered remote. 19 <Page> CREDIT SUISSE INSTITUTIONAL FUND, INC. -- INTERNATIONAL FOCUS PORTFOLIO PRIVACY POLICY NOTICE (unaudited) IMPORTANT PRIVACY CHOICES FOR CONSUMERS We are committed to maintaining the privacy of every current and prospective customer.

In general, the market was aided by optimism that a reviving U.S. economy would lead to better corporate earnings results in due course. In fact, earnings reported late in the period exceeded expectations in many cases. However, the period ended on an uncertain note in the stock market. While the economic news remained generally good, inflation pressures appeared to be building. The Federal Reserve hinted that rate hikes could therefore come sooner rather than later, and stocks gave back some gains in March and April. The Portfolio underperformed its benchmark for the period, attributable in large part to its general avoidance of lower-quality stocks -- e.g., those representing companies with little or no earnings and leveraged balance sheets - -- which had strong showings in the October-through-January span. The Portfolio outperformed its benchmark in the period's second half, as higher-quality stocks began to gain favor in the market. Stocks that hampered the Portfolio included its energy and technology holdings. On the positive side, the Portfolio's financial services, healthcare and consumer staples stocks aided its return. With regard to portfolio activity, we increased our exposure to the energy sector, based on valuations, along with our contrarian view on oil and gas prices. While we expect energy prices to decline from current levels, we think that relatively high -- and higher-than-consensus -- forecast prices will likely prevail. We also believe that energy services companies could benefit from increased spending by exploration and production companies. Elsewhere of note, we ended the period overweighted in the healthcare and producer durables sectors, and underweighted in the utilities and consumer-discretionary areas. We continued to underweight the financial-services sector -- which accounts for more than 30% of the Portfolio's benchmark -- in order to avoid excessive interest-rate risk. Going forward, we will continue to focus on companies that, in our view, put their cash to productive use. We look for companies that use excess cash accumulated in the ongoing economic upturn in ways that can add to shareholder value via share buybacks, higher dividend payouts or investments in organic growth. 1 <Page> The Credit Suisse Value Team Stephen J.

In general, the market was aided by optimism that a reviving U.S. economy would lead to better corporate earnings results in due course. In fact, earnings reported late in the period exceeded expectations in many cases. The period ended on an uncertain note in the stock market. While the economic news remained generally good, inflation pressures appeared to be building. The Federal Reserve hinted that rate hikes could therefore come sooner rather than later, and stocks gave back some gains in April. The Portfolio's outperformance was largely attributable to a sharp increase in value of its holding of Prescient Systems, Inc. ("Prescient"), a privately held concern that provides supply chain software. Because the Portfolio is small (only about $2 million in net assets as of April 30, 2004), the increase had a significant impact on the Portfolio's net asset value. On the last day of the period covered by the report, Prescient represented about 16% of the Portfolio's assets. Such outperformance is not necessarily representative of the Portfolio's long-term performance. The Portfolio also benefited from good stock selection in the consumer discretionary, healthcare and energy sectors. The Portfolio remained well-diversified by sector, with overweightings in the consumer discretionary and energy sectors as of the end of the period, along with a modest underweighting in the healthcare and financial services areas. With respect to noteworthy recent portfolio activity, new purchases included a company that provides physical intellectual property components for the design and manufacture of complex integrated circuits. The company offers libraries that facilitate semiconductor design, demand for which should increase as leading edge technologies become more expensive to develop. We also added to a video game manufacturer whose products are entering a favorable cycle in our view. On the sell side, our activity included eliminating certain technology, energy and healthcare stocks based on valuations, in the wake of strong performance. Going forward, while our general view on the U.S. economy and corporate profits is positive, we believe that market volatility could remain high for a spell, with stocks vulnerable to interest-rate worries and the ever-present 4 <Page> threat of geopolitical tensions. Still, on a company-specific basis, we also believe that good opportunities exist in a variety of sectors, and we will remain focused on companies we deem to be well-managed companies with healthy finances and compelling longer-term business models.

In general, the market was aided by optimism that a reviving U.S. economy would lead to better corporate earnings results in due course. In fact, earnings reported late in the period exceeded expectations in many cases. The period ended on an uncertain note in the stock market. While the economic news remained generally good, inflation pressures appeared to be building. The Federal Reserve hinted that rate hikes could therefore come sooner than later, and stocks gave back some gains in March and April. The Portfolio underperformed its benchmark, attributable in large part to the market's rally (over the October-through-January span) being paced by stocks of companies with lackluster or even negative economic profit. However, our focus remained on companies we deemed to have compelling economic profit characteristics -- i.e., those that earn a return-on-invested-capital that exceed their cost of capital or have improving profitability trends. While the trend reversed late in the period, lower-quality stocks nonetheless outperformed for the six months as a whole. We maintained a bottom-up stock selection process, and as such remained focused on company selection. Recent activity in the Portfolio involved the purchase and sale of stocks on company-specific factors. On the purchase side, new positions included a leading provider of securities custody services. We believe it stands to benefit from increased activity in a recovering stock market. We also took a position in a conglomerate whose leading position in a number of industries has generated substantial cashflow and profit. Our sales included a department-store retailer whose stock, after a lengthy rally, had reached fair value in our estimation. As a result of our recent strategic trading activity, we ended the period with overweights in the industrials, consumer discretionary, and materials sectors; and underweights in the consumer staples, healthcare, information technology, and telecommunications sectors. Going forward, we will continue to adhere to our bottom-up investment approach. Our efforts will remain focused on striving to identify companies with the strongest economic profit characteristics and compelling valuation. We believe that over time economic profit provides a reliable, objective gauge 7 <Page> of corporate performance and that over time the market tends to reward outstanding performance. D.

The Portfolio slightly trailed its benchmark for the period; the underperformance occurred in the period's first half, in part due to the Portfolio's underweighting or avoidance of certain higher-risk stocks (e.g., stocks of companies with low or no earnings), as such stocks initially rallied on expectations that an improving economy would benefit them the most. However, these types of stocks underperformed over the February-through-April span, a period in which the Portfolio's relative performance improved. From a sector perspective, its healthcare, consumer discretionary and transportation stocks aided its performance, while the Portfolio's consumer staples, producer durables, and technology holdings hampered return. In terms of sector allocation, which results from our bottom-up stock-selection process, we maintained a significant overweight in the consumer discretionary area, where our adjustments included establishing a position in a food/beverage retail chain exhibiting solid growth in the U.S. and abroad. Within the media subsector, which we also continued to overweight, we shifted a little more toward "new media" companies. We believe that these companies have the potential for strong growth rates as advertisers allocate more dollars to Internet ad campaigns over time. Elsewhere of note, we remained underweight in the consumer staples sector, where we continue to see relatively few compelling growth stories. We became somewhat more underweighted in technology, paring exposure to certain names based on valuations and company growth prospects. We also became a little more underweighted in financial services, where we sold an asset management stock that had become richly valued in the wake of good 10 <Page> performance. However, we continued to see opportunities in the sector as well. We established a position in an outsourcing services company that we believe stands to benefit from an improving labor market. We continued to slightly overweight the producer durables sector, reflecting our view that the group is well leveraged to an expanding economy and a recovery in industrial America. Our investment process remains bottom-up and focused on stock selection. We continue to look for companies we think are leveraged to benefit from an improving economy along with companies leveraged to secularly improving businesses. Jeffrey T. Rose Marian U.

Stocks initially rose, continuing a rally begun in March 2003 on improvements in U.S. economic data and corporate profits. Markets finished the period on a weak note, however, hurt by fears of rising U.S. interest rates, worries that China's strong growth would be reined in, and renewed geopolitical concerns. The Portfolio trailed its benchmark for the period, due primarily to the underperformance of its consumer-discretionary holdings. On the positive side, factors that helped the Portfolio included its overweighting in the healthcare sector, which had good performance for the six months. In terms of noteworthy recent strategies, we have been adjusting our exposure to semiconductor stocks, which had strong performance in 2003 due to an increase in global demand for semiconductors and electronic components. We believe that growth for electronic components should moderate going forward. In that context, we decided to sell certain stocks, such as a large manufacturer of commodity memory components, after they appreciated to reach our price target. Going forward, while our general view on the U.S. economy and corporate profits is positive, we believe that market volatility could remain high for a spell, with stocks vulnerable to interest-rate worries and the ever-present threat of geopolitical tensions. Still, on a company-specific basis, we also believe that good opportunities exist in a variety of sectors, and we will remain focused on companies we believe have the financial wherewithal to execute their longer-term business models.

Sentiment and perceptions were fairly consistent in November through March, and then shifted abruptly in April. In each case, expectations regarding the directional trend of interest rates appeared to be the key influence on market returns. The November-March period was generally characterized by stable-to-falling bond yields even as the economic backdrop continued to strengthen. While many indicators of economic activity prompted jitters that the Federal Reserve might raise rates, the collective impact of others (I.E., low inflation, weak jobs growth, high productivity) seemed to leave enough slack in the economy for rates to remain unchanged. Prices of Treasury securities additionally benefited from significant purchases by foreign central banks and risk aversion in response to terrorist attacks in Spain and the Middle East. All of this changed rapidly, however, with the release of the March payroll report on April 2. This better-than-expected measure of employment, coupled with rising inflation metrics, a surge in oil prices, and remarks by Fed Chairman Alan Greenspan, was widely interpreted as signalling that the Fed would most likely be compelled to tighten monetary policy. Investors re-evaluated their interest-rate expectations and began to sell bonds aggressively. By the end of April, yields had risen sharply across the maturity spectrum. We attribute the Portfolio's mild underperformance versus the benchmark in the half-year mainly to two aspects of our strategy: - We kept the portfolio's average duration somewhat shorter than that of the benchmark out of concern that improving economic activity might push bond yields higher. As we have described, though, yields declined in much of the period, and the Portfolio's relative return was hurt accordingly. - We held small positions in foreign currencies. While these positions augmented performance early in the period, unanticipated appreciation in the U.S. dollar at the end of the period meant that our currency holdings made a modestly negative contribution to performance in the half-year as a whole. 16 <Page> On the positive side of the ledger, the Portfolio's relative return benefited from our positions in investment-grade corporate bonds. We overweighted corporates, which outperformed the benchmark, and emphasized comparatively lower-quality issues, which fared especially well. We also held a small exposure to German government bonds that outperformed their U.S. Treasury counterparts. Credit Suisse Fixed Income Management Team Jo Ann Corkran Michael Buchanan Kevin D.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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 seven managed investment funds, of which six are contained in this report. The Large Cap Value Portfolio ("Large Cap Value"), the Capital Appreciation Portfolio ("Capital Appreciation"), the Small Cap Growth Portfolio ("Small Cap Growth"), 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. Effective April 28, 2004, the Small Cap Growth Portfolio closed to new investments, except for the reinvestments of dividends and distributions. Investment objectives for each Portfolio are as follows: Large Cap Value and Investment Grade Fixed Income seek total return; Small Cap Growth seeks capital growth; Capital Appreciation and Select Equity seek long-term capital appreciation; and Harbinger seeks long-term growth of capital. 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 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 independent third party which has been approved by the Board of Directors to fair value certain portfolio securities. 54 <Page> 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, Small Cap Growth, 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 for Investment Grade Fixed Income. However, to the extent that a net realized capital gain can be reduced by a capital loss carryover, 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 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 55 <Page> 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. The Portfolio will enter into forward foreign currency contracts primarily for hedging purposes. Forward foreign currency contracts are adjusted by the daily 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, 2004, Investment Grade Fixed Income had the following open forward foreign currency contracts: <Table> <Caption> FOREIGN CURRENCY EXPIRATION TO BE CONTRACT CONTRACT UNREALIZED FORWARD FOREIGN CURRENCY CONTRACT DATE PURCHASED/(SOLD) AMOUNT VALUE GAIN (LOSS) - --------------------------------- ---------- ----------------- --------- --------- ----------- British Pound 7/2/2004 L (36,500) $ (66,590) $ (64,393) $ 2,197 European Economic Unit 7/2/2004 EURO (56,000) (67,453) (66,952) 501 European Economic Unit 7/2/2004 EURO (55,000) (66,463) (65,757) 706 European Economic Unit 7/2/2004 EURO (20,000) (24,540) (23,912) 628 Japanese Yen 7/2/2004 Y 7,145,992 67,453 64,878 (2,575) Japanese Yen 7/2/2004 Y 6,985,220 66,463 63,418 (3,045) Japanese Yen 7/2/2004 Y 7,100,000 68,269 64,460 (3,809) Japanese Yen 7/2/2004 Y 7,000,000 67,530 63,552 (3,978) --------- --------- ----------- $ 44,669 $ 35,294 $ (9,375) ========= ========= =========== </Table> 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. 56 <Page> J) FUTURES -- Each Portfolio may enter into futures contracts to the extent permitted by its investment objectives and policies. Upon entering into a futures contract, a 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, 2004, Investment Grade Fixed Income had the following open futures contracts: <Table> <Caption> UNREALIZED NUMBER OF EXPIRATION CONTRACT CONTRACT APPRECIATION/ FUTURES CONTRACTS CONTRACTS DATE AMOUNT VALUE (DEPRECIATION) - ----------------- --------- ---------- ---------- ---------- --------------- U.S. Treasury 5 Year Notes Futures 3 06/21/04 $ 330,343 $ 329,812 $ (531) U.S. Treasury Bonds Futures 5 06/21/04 567,502 535,469 (32,033) ---------- ---------- --------------- 897,845 865,281 (32,564) ---------- ---------- --------------- U.S. Treasury 2 Year Notes Futures (4) 06/29/04 (852,700) (850,188) 2,512 ---------- ---------- --------------- $ 45,145 $ 15,093 $ (30,052) ========== ========== =============== </Table> K) SECURITIES LENDING -- Loans of securities are required at all times to be secured by collateral at least equal to 102% of the market value of domestic securities on loan (including any accrued interest thereon) and 105% of the market value of foreign securities on loan (including any accrued interest thereon). Cash collateral received by the Portfolios 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 Funds' 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. 57 <Page> The market value of securities on loan to brokers and the value of collateral held by each Fund with respect to such loans at April 30, 2004 are as follows: <Table> <Caption> MARKET VALUE OF VALUE OF PORTFOLIO SECURITIES LOANED COLLATERAL RECEIVED --------- ----------------- ------------------- Large Cap Value $ 2,926,020 $ 3,018,770 Small Cap Growth 420,466 443,342 Select Equity 702,743 745,350 Capital Appreciation 1,752,978 1,838,701 Harbinger 250,128 256,486 Investment Grade Fixed Income 1,718,935 1,755,601 </Table> Prior to March 17, 2004, Credit Suisse First Boston ("CSFB"), an affiliate of CSAM, had been engaged by the Portfolios to act as the Portfolios' securities lending agent. The Fund earned no income from securities lending through the period ended March 17, 2004. Effective March 17, 2004, 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 with each Portfolio receiving 70% and SSB receiving 30% of the earnings from the investment of cash collateral or any other securities lending income in accordance with the provisions of the securities lending agency agreement. Securities lending income is accrued as earned. L) 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 Small Cap Growth, 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, 58 <Page> the prices realized from such sales could differ from the price originally paid by the Portfolio or the current carrying values, and the difference could be material. NOTE 2. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES CSAM serves as investment adviser for each Portfolio. For its investment advisory services, CSAM is entitled to receive a fee from the Portfolios based on the following fee schedules: <Table> <Caption> PORTFOLIO ANNUAL RATE --------- ----------- Large Cap Value 0.75% of average daily net assets Small Cap Growth 0.90% of average daily net assets Select Equity 0.50% of average daily net assets Capital Appreciation 0.50% of average daily net assets Harbinger 1.00% of average daily net assets Investment Grade Fixed Income 0.30% of average daily net assets </Table> For the six months ended April 30, 2004, investment advisory fees earned, voluntarily waived and expenses reimbursed for each Portfolio were as follows: <Table> <Caption> GROSS NET ADVISORY ADVISORY EXPENSE PORTFOLIO FEE WAIVER FEE REIMBURSEMENT --------- ---------- --------- -------- ------------- Large Cap Value $ 110,979 $ (84,786) $ 26,193 $ -- Small Cap Growth 94,859 (78,626) 16,233 -- Select Equity 37,503 (37,503) -- (14,136) Capital Appreciation 22,853 (22,853) -- (31,566) Harbinger 12,878 (12,878) -- (33,223) Investment Grade Fixed Income 18,087 (18,087) -- (59,668) </Table> Credit Suisse Asset Management Securities, Inc.

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. 63 <Page> CREDIT SUISSE INSTITUTIONAL FUND, INC.
