Exhibit 17(b) - -------------------------------------------------------------------------------- Dear Shareholder: We are pleased to provide you with this Annual Report for the Merrill Lynch Funds For Institutions Series. Merrill Lynch Premier Institutional Fund For the year ended April 30, 2000, Merrill Lynch Premier Institutional Fund's net yield was 5.38%. The Fund's seven-day annualized yield as of April 30, 2000, was 6.00%. The average portfolio maturity for the Merrill Lynch Premier Institutional Fund at April 30, 2000, was 62 days, compared to 64 days at October 31, 1999. During the period ended April 30, 2000, Merrill Lynch Premier Institutional Fund maintained an average life ranging from a low of 52 days to a high of 71 days. The US economy has shrugged off repeated attempts by the Federal Reserve Board to slow it down, and appears to be accelerating at a faster pace in recent months. While it has been our opinion that the Federal Reserve Board would continue to raise interest rates, value in some longer-dated securities has led us to maintain our average life in the 60-day range. Much of our effort early in the period was focused on preparation for the arrival of the year 2000 (Y2K). Even though we believed that the Federal Reserve Board had taken adequate steps to ensure that markets would remain orderly, we thought that it was important to provide enhanced shareholder liquidity toward year-end. As such, we focused the Fund's investments on securities maturing in December. As the period progressed and it became apparent that the Federal Reserve Board would continue to raise interest rates, we increased our position in floating rate securities since we believed that they would benefit the Fund as interest rates increased. Later in the period, we took advantage of the relatively steep yield curve by investing in one-year bank issues. Looking ahead, we expect the rapid growth of the US economy coupled with signs of accelerating price pressures to keep the Federal Reserve Board in a tightening mode. Merrill Lynch Institutional Fund For the year ended April 30, 2000, Merrill Lynch Institutional Fund's net yield was 5.32%. The Fund's seven-day annualized yield as of April 30, 2000, was 5.96%. The average portfolio maturity for the Merrill Lynch Institutional Fund at April 30, 2000, was 62 days, compared to 67 days at October 31, 1999. During the period ended April 30, 2000, Merrill Lynch Institutional Fund maintained an average life ranging from a low of 51 days to a high of 72 days.

Merrill Lynch Rated Institutional Fund For the year ended April 30, 2000, Merrill Lynch Rated Institutional Fund's net yield was 5.29%. The Fund's seven-day annualized yield as of April 30, 2000, was 5.85%. The average portfolio maturity for the Merrill Lynch Rated Institutional Fund at April 30, 2000, was 52 days, compared to 39 days at October 31, 1999. During the period ended April 30, 2000, Merrill Lynch Rated Institutional Fund maintained an average life ranging from a low of 28 days to a high of 55 days. The US economy has shrugged off repeated attempts by the Federal Reserve Board to slow it down, and appears to be accelerating at a faster pace in recent months. While it has been our opinion that the Federal Reserve Board would continue to raise interest rates, value in some longer-dated securities has led us to maintain our average life in the 50-day range.

Looking ahead, we expect the rapid growth of the US economy coupled with signs of accelerating price pressures to keep the Federal Reserve Board in a tightening mode. Merrill Lynch Government Fund For the year ended April 30, 2000, Merrill Lynch Government Fund's net yield was 5.22%. The Fund's seven-day annualized yield as of April 30, 2000, was 5.79%. The average portfolio maturity for the Merrill Lynch Government Fund at April 30, 2000, was 55 days, compared to 56 days at October 31, 1999. For the six months ended April 30, 2000, Merrill Lynch Government Fund generally held its average life close to the 60-day area. This reflected our involvement in a steep yield curve environment that was driven initially by Y2K concerns and a more restrictive monetary policy. For the balance of 1999, we prepared the Fund for Y2K. We reduced our overnight position from 30% of net assets to 18% by 1999 year-end. Conversely, we added a three-month agency exposure as financing levels declined dramatically. On the floating rate front, we favored securities with an interest rate floor that were reset off the weekly three-month Treasury bill auction. Recent months have seen a pronounced change in the Fund's structure. We believed that, despite rising interest rates, the lack of Treasury supply resulting from diminished issuance and buybacks would invert the yield curve. As a result, we adopted a barbell structure. At April 30, 2000, nearly 50% of the Fund's net assets were invested in overnight issues, with 30% in floating rate issues and the balance in the one-year sector. This allows the greater portion of the Fund's assets to take advantage of rising interest rates while the longer-term investments should provide yield enhancement and potential price appreciation. 2 Merrill Lynch Treasury Fund For the year ended April 30, 2000, Merrill Lynch Treasury Fund's net yield was 4.83%. The Fund's seven-day annualized yield as of April 30, 2000, was 5.54%. The average portfolio maturity for Merrill Lynch Treasury Fund at April 30, 2000, was 54 days, compared to 55 days at October 31, 1999. For the six months ended April 30, 2000, Merrill Lynch Treasury Fund largely maintained its average life near the 60-day limit as relatively tight technicals fostered a steep yield curve and a favorable interest rate environment. The first half of the period dealt with uncertainty surrounding the Y2K phenomena. We believed that while our asset base usually grows temporarily at year-end, the assets attracted by this event would be invested for an extremely short term as a result of their tenuous nature. As a result, the Fund's average life fell to a low of 30 days in recognition that preservation of capital would take precedent over yield. More recently, we have taken a more aggressive stance. Changes to the Treasury's auction calendar have steepened the yield curve in the front end and dramatically tightened Treasury liquidity spreads. As a result, we eliminated our Treasury note position and extended the Fund's average life to the high 50-day area. We have targeted early May, June and July bills as sectors with value. Reinvestment of April cash management bills coupled with the results of the Federal Reserve Board's meeting on May 16 have continued to keep the front end of the yield curve steep. Merrill Lynch Institutional Tax-Exempt Fund For the year ended April 30, 2000, Merrill Lynch Institutional Tax-Exempt Fund's net yield was 3.36%. The Fund's seven-day annualized yield as of April 30, 2000, was 4.28%. The average portfolio maturity for Merrill Lynch Institutional Tax-Exempt Fund at April 30, 2000, was 50 days, compared to 65 days at October 31, 1999. We continued to pursue a neutral investment strategy throughout the six-month period ended April 30, 2000. Tight labor conditions persisted throughout the period, while economic growth continued at an accelerated rate. As a result of an increase in energy prices, inflation, which had remained somewhat subdued for the majority of the period, began to show signs of filtering into the economy by the end of the period. The Federal Reserve Board continued its approach to monetary policy by increasing the Federal Funds rate in a series of 25 basis point (0.25%) moves to slow economic growth. The latest move came at the May 16, 2000 Federal Open Market Committee meeting, when the Federal Funds rate was increased to 6.50%. We allowed the average life of the Fund, which began the period in the 70-day range, to decline steadily and to end the period in the 50-day range. In an attempt to stabilize the Fund's yield during periods when variable rate demand note (VRDN) rates became volatile, we pursued short-term municipal notes and purchased tax-exempt commercial paper in the 60-day to 90-day range. At the beginning of the period, we anticipated that short-term municipal issuance would subside with the coming of Y2K, however a steady inventory of smaller local municipal note issuance persisted. This issuance allowed yields on one-year municipal notes to increase from the 3.70% range to the 4.00% range in December and end the period in the 4.25% range. In December, we had prepared for an anticipated increase in subscriptions from individuals seeking a safe haven from Y2K and from corporations taking advantage of an anticipated spike in VRDN yields that were caused by seasonal year-end factors. However, the Fund's net assets did not increase but declined. As for the short-term, tax-exempt municipal market in general, year-end cash flows were similar to those of the previous year with no noticeable irregularities created by the effects of Y2K. The Fund was well situated in January and February as a seasonal increase in subscriptions allowed yields on VRDN securities to decline below attractive tax-equivalent levels. This reduction in VRDN yield levels allowed 3 the Fund to perform well because of its smaller exposure to such securities. In March, we began to increase the Fund's exposure to VRDNs to seek to take advantage of the anticipated rise in VRDN yield levels offered during the annual tax season. The net assets of the Fund, which began the period at $2.4 billion, increased to a high of nearly $2.5 billion on December 2, 1999 before ending the period at $2.1 billion. In the coming months, we will continue to monitor the changes in the economic environment in accordance with the Fund's investment strategy. As inflationary data begins to show signs of accelerating, the Federal Reserve Board remains prepared to continue to raise short-term interest rates in an effort to slow economic growth. The emphasis will be on how high short-term interest rates will have to go in order to slow the domestic economy. However, with the equity markets beginning to become more volatile, it has become unclear as to what effect this will have on the Federal Reserve Board's agenda. We will begin the upcoming period pursuing a more defensive approach to the market as we continue through a period of higher short-term municipal rates created from seasonal tax-related redemptions. We expect to continue to concentrate on maintaining tax-exempt commercial paper in the 60-day to 90-day range while looking to increase the Fund's exposure to VRDNs. We will also pursue short-term municipal notes when yield levels warrant it. Finally, we will closely monitor credit quality while at the same time seek to maintain an attractive tax-exempt yield for our shareholders. We thank you for your continued interest in Merrill Lynch Funds For Institutions Series, and we look forward to serving your investment needs in the months and years ahead. Sincerely, /s/ Robert W.

Significant Accounting Policies Merrill Lynch Funds For Institutions Series (the "Trust") was organized as a Massachusetts business trust on May 7, 1987, and is registered under the Investment Company Act of 1940 as a diversified, open-end management company. On June 15, 1998, Merrill Lynch Rated Institutional Fund commenced operations as a separate series of the Trust. On January 27, 1997, Merrill Lynch Premier Institutional Fund commenced operations as a separate series of the Trust. The Trust has a fiscal year end of April 30. The Trust's financial statements are prepared in accordance with generally accepted accounting principles, which may require the use of management accruals and estimates. The following is a summary of significant accounting policies consistently followed by the Trust in conformity with generally accepted accounting principles. (a) The value of the Premier Institutional, Institutional, Rated Institutional, Government and Treasury Fund portfolio securities is determined on the basis of fair value as determined in good faith by the Board of Trustees (the "Trustees") of the Trust. In determining fair value, securities for which market quotations are readily available are valued at market value. Other securities, if any, are valued at their fair value in the best judgment of Fund Asset Management, L.P., ("FAM") under procedures established by, and under the supervision of, the Trustees. Securities with remaining maturities of 60 days or less are valued by use of the amortized cost method. Institutional Tax-Exempt Fund's portfolio securities are carried at amortized cost which approximates market value. For the purpose of valuation, the maturity of a variable rate demand instrument is deemed to be the next coupon date on which the interest rate is to be adjusted. In the case of a floating rate instrument, the remaining maturity is deemed to be the demand notice payment period. (b) It is the Trust's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. (c) Realized gains and losses on investments are computed on the basis of identified cost of the security sold. (d) Security transactions are accounted for on the date the securities are purchased or sold (the trade date). Interest income (after adjustment for amortization of premium or accretion of discount) is recorded as earned. (e) Prepaid registration fees are charged to income as the related shares are sold. (f) Repurchase agreements--The Premier Institutional Fund, the Institutional Fund, the Rated Institutional Fund and the Government Fund invest in U.S. Government & Agency securities pursuant to repurchase agreements with member banks of the Federal Reserve System or primary dealers in U.S. Government securities. Under such agreements, the bank or primary dealer agrees to repurchase the security at a mutually agreed upon time and price. The Trust takes possession of the underlying securities, marks to market such securities daily and, if necessary, receives additional securities to ensure that the contract is adequately collateralized. (g) During the year ended April 30, 2000, Merrill Lynch Institutional Tax-Exempt Fund reclassified amounts to reflect a decrease of $6,729 and $115,302 in accumulated capital losses and undistributed net investment income, respectively, as a result of permanent differences arising from different treatments of market discount for book and tax purposes. 2.

For the period ended April 30, 1999, the effective fee payable to FAM was 0.16% of the Fund's average daily assets. FAM has agreed to waive a portion of its advisory fees for the Institutional, Government, Treasury and Tax-Exempt Funds. The effective fee payable to FAM will be at the annual rate of 0.20% of each Fund's average daily net assets. FAM may discontinue waiver of the fee in whole or in part at any time without notice. For the period ended April 30, 2000, FAM waived a portion of its fees amounting to $10,758,313 for the Institutional Fund, $3,018,131 for the Government Fund, $1,024,599 for the Treasury Fund and $5,377,309 for the Institutional Tax-Exempt Fund.

Distributions The Funds declare dividends daily, pay dividends monthly and automatically reinvest such dividends in additional Fund shares at net asset value, unless shareholders request payment in cash. Dividends for the Premier Institutional, Institutional, Rated Institutional, Government and Treasury Funds are declared from the total net investment income plus or minus realized gains or losses, if any, on investments. Dividends for the Institutional Tax-Exempt Fund are declared from net investment income- excluding discounts earned other than original issue discounts. Net realized capital gains, if any, are normally distributed annually, after deducting prior years' loss carryovers. The Fund may distribute capital gains more frequently than annually in order to maintain the Fund's net asset value at $1.00 per share. At April 30, 2000, the Institutional Tax-Exempt Fund had net capital loss carryovers of $128,519 of which $124,729 expire in the year 2003, and $3,790 expire in 2007. 5. Trustees' Fees Each Trustee who is not affiliated with the Trust or its adviser is paid an annual fee of $36,000 by the Trust. Trustees' fees are allocated among the six series of the Trust based on the net assets under management. 54 - -------------------------------------------------------------------------------- INDEPENDENT AUDITORS' REPORT ================================================================================ To the Trustees of and the Shareholders of Merrill Lynch Funds For Institutions Series: We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of Merrill Lynch Funds For Institutions Series (the "Trust"), consisting of Merrill Lynch Premier Institutional Fund, Merrill Lynch Institutional Fund, Merrill Lynch Rated Institutional Fund, Merrill Lynch Government Fund, Merrill Lynch Treasury Fund, and Merrill Lynch Institutional Tax-Exempt Fund (the "Funds"), each a separate series of the Trust, as of April 30, 2000, and the related statements of operations for the year then ended, and the statements of changes in net assets and the financial highlights for each of the respective periods then ended.
