Gary M. Gardner Secretary February __, 2000 COMBINED PROSPECTUS/PROXY STATEMENT Dated February __, 2000 INDEPENDENCE SQUARE INCOME SECURITIES, INC. c/o Bellevue Park Corporate Center 400 Bellevue Parkway Wilmington, DE 19809 (610) 964-8882 BLACKROCK FUNDS(SM) Bellevue Park Corporate Center 400 Bellevue Parkway Wilmington, DE 19809 (800) 441-7762 This Combined Prospectus/Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of Independence Square Income Securities, Inc. ("ISIS") in connection with a Special Meeting (the "Meeting") of Shareholders ("Shareholders") to be held on March __, 2000 at __:__ a.m./p.m. (Eastern time) at the offices of BlackRock Institutional Management Corporation, Bellevue Park Corporate Center, 400 Bellevue Parkway, Fourth Floor Conference Room, Wilmington, Delaware 19809, at which Shareholders will be asked to consider and approve a proposed Agreement and Plan of Reorganization dated December __, 1999 (the "Reorganization Agreement"), by and between ISIS and BlackRock Funds(SM) ("BlackRock"), and the matters contemplated therein (the "Reorganization"). A copy of the Reorganization Agreement is attached as Appendix A. ISIS is registered as a closed-end management investment company under the Investment Company Act of 1940, as amended (the "1940 Act"). BlackRock is registered as an open-end management investment company under the 1940 Act. BlackRock Institutional Management Corporation ("BIMC") currently serves as investment adviser to ISIS. BlackRock Advisors, Inc. ("BlackRock Advisors") currently serves as investment adviser for BlackRock and BlackRock Financial Management, Inc. ("BFM") currently serves as sub-adviser for BlackRock with respect to its High Yield Bond Portfolio (the "High Yield Bond Portfolio"). BIMC, BlackRock Advisors and BFM are each majority-owned, indirect subsidiaries of PNC Bank, N.A. ("PNC Bank"). In reviewing the proposed Reorganization, the Board of Directors of ISIS considered among other things: the reasons for the Reorganization; the terms of the Reorganization; the opportunity to combine ISIS and the High Yield Bond Portfolio to create a single, larger consolidated asset base; the investment objectives and policies of each of the Funds; BlackRock's service providers; the recommendations of BIMC and BlackRock Advisors with respect to the Reorganization; the effect of the Reorganization on ISIS; the fact that the Reorganization would constitute a tax-free reorganization; and the fact that the interests of Shareholders would not be diluted as a result of the Reorganization. The Reorganization Agreement provides that ISIS will transfer all of its assets and liabilities to the High Yield Bond Portfolio. In exchange for the transfer of these assets and liabilities, BlackRock will issue Series B Investor Shares of the High Yield Bond Portfolio to ISIS. The transaction is expected to occur on March ___, 2000, or as soon thereafter as is practicable. ISIS offers one class of shares. The High Yield Bond Portfolio offers six classes of shares. One class of shares offered by the High Yield Bond Portfolio, Series B Investor Shares, is the class of shares which Shareholders of ISIS will receive in the Reorganization, as further described in "Information Relating to the Proposed Reorganization -- Description of the Reorganization Agreement." ISIS will make a liquidating distribution of Series B Investor Shares to the Shareholders of ISIS, so that a holder of shares in ISIS will receive Series B Investor Shares of the High Yield Bond Portfolio with the same aggregate net asset value as the ISIS shares held by the Shareholder immediately before the transaction. Following the Reorganization, Shareholders of ISIS will be shareholders of the High Yield Bond Portfolio, and ISIS will be dissolved under state law and de-registered under the 1940 Act. The High Yield Bond Portfolio is currently conducting investment operations as described in this Combined Prospectus/Proxy Statement. This Combined Prospectus/Proxy Statement sets forth the information that a Shareholder of ISIS should know before voting on the Reorganization Agreement (and related transactions), and should be retained for future reference. The Prospectus relating to Series B Investor Shares of the High Yield Bond Portfolio, which describes the High Yield Bond Portfolio, 2 accompanies this Combined Prospectus/Proxy Statement and is incorporated herein by reference. Additional information is set forth in the Statements of Additional Information relating to the Series B Investor Shares of the High Yield Bond Portfolio and this Combined Prospectus/Proxy Statement, which are dated January 28, 1999 and February __, 2000, respectively, each of which is incorporated herein by reference. Each of these documents is on file with the Securities and Exchange Commission (the "SEC"), and is available without charge upon oral or written request by writing or calling either ISIS or BlackRock at the respective addresses or telephone numbers indicated above. This Combined Prospectus/Proxy Statement constitutes the Proxy Statement of ISIS for the meeting of its Shareholders, and BlackRock's Prospectus for Series B Investor Shares of the High Yield Bond Portfolio that have been registered with the SEC and are to be issued in connection with the Reorganization. This Combined Prospectus/Proxy Statement is expected to first be sent to Shareholders on or about February __, 2000.

ISIS' Semi-Annual Report to Shareholders and its Annual Report to Shareholders may be obtained free of charge by calling 1-800-852-4750 or writing c/o Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, DE 19809. The High Yield Bond Portfolio's Annual Report to Shareholders may be obtained free of charge by calling 1-800- 441-7762 or writing Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, Delaware 19809. Proposed Reorganization. Based upon their evaluation of the relevant information presented to them, and in light of their fiduciary duties under federal and state law, the Board of Directors of ISIS and the Board of Trustees of BlackRock, including a majority of their members who are not "interested persons" within the meaning of the 1940 Act, have determined that the proposed Reorganization is in the best interests of their Fund's respective shareholders and that the interests of such shareholders will not be diluted as a result of such Reorganization. Reasons for the Reorganization. When ISIS was organized in 1971, a closed- end structure was chosen as most appropriate for ISIS' method of operation because it was believed that such a structure, among other things, would permit management of its portfolio consistent with its investment objective and policies without the pressures and constraints to which open-end investment companies are subject as a result of cash inflows and redemptions. However, as a result of the relatively modest size of ISIS' assets (approximately $31.3 million as of September 30, 1999), changes in the securities markets, and changes to the way mutual funds account for certain securities, it has become increasingly difficult for ISIS to maintain its competitive level of dividends to Shareholders. BIMC and BlackRock Advisors have recommended that ISIS be reorganized into the High Yield Bond Portfolio as described in this Combined Prospectus/Proxy Statement. In light of this recommendation, after consideration of the reasons therefor and the proposed operations of the High 5 Yield Bond Portfolio after the Reorganization, and in consideration of the fact that the Reorganization will be tax-free and will not dilute the interests of Shareholders, the Board of Directors of ISIS has authorized the Reorganization Agreement and recommended approval of the Reorganization by Shareholders. Federal Income Tax Consequences. Drinker Biddle & Reath LLP, counsel to ISIS and to its Board of Directors, will issue an opinion (based on certain assumptions) as of the effective time of the Reorganization that the transaction will not give rise to the recognition of income, gain or loss for federal income tax purposes to ISIS, the High Yield Bond Portfolio or their respective shareholders. See "Information Relating to the Proposed Reorganization - Federal Income Tax Consequences." Overview of ISIS and the High Yield Bond Portfolio. The investment objective of ISIS is to seek as high a level of current income as is consistent with prudent investment. The High Yield Bond Portfolio's investment objective is to seek to provide current income by investing primarily in non-investment grade bonds. Each pursues its investment objective by investing primarily in debt securities. However, there are differences in each Fund's investment policies. For example, ISIS must invest at least 60% of its assets in: (1) marketable straight debt securities which are rated at the time of purchase within the four highest grades assigned by Moody's Investors Service, Inc. (Aaa, Aa, A or Baa), Standard & Poor's Ratings Group, Division of McGraw Hill (AAA, AA, A or BBB) or Fitch IBCA, Inc. (AAA, AA, A or BBB); (2) securities of, or guaranteed by, the United States government, its agencies or instrumentalities; (3) securities (payable in U.S. dollars) of, or guaranteed by, the government of Canada or of a Province of Canada under circumstances that would not subject the Fund to payment of U.S. Interest Equalization Tax; (4) commercial paper of companies having, at the time of purchase, an issue of outstanding debt securities rated as described in (1) above; and (5) cash or cash equivalents. ISIS may invest up to 40% of its assets in non-investment grade debt securities (i.e., rated lower than Baa by Moody's Investor Services, Inc. or rated lower than BBB by Standard & Poor's Ratings Group and Fitch-IBCA, Inc.). At least 25% of ISIS' assets must be invested in the securities of utility companies. As stated in its objective, the High Yield Bond Portfolio invests primarily in non-investment grade bonds. The High Yield Bond Portfolio normally invests at least 80% of its total assets 6 in bonds or convertible securities and at least 65% of its total assets in non- investment grade bonds. Non-investment grade bonds are commonly referred to as "junk bonds." The High Yield Bond Portfolio is not permitted to invest 25% or more of its assets in the utility industry or any one industry. See "Comparison of Investment Policies and Risk Factors" below and the High Yield Bond Portfolio's Prospectus, which is incorporated by reference herein, for a more detailed description of the investment objectives and policies of ISIS and the High Yield Bond Portfolio. Certain Arrangements with Service Providers -- ISIS. BIMC serves as the investment adviser for ISIS. BIMC is an indirect, majority-owned subsidiary of PNC Bank. Until June 18, 1998, PNC Bank served as sub-adviser to ISIS. On June 18, 1998, BIMC assumed PNC Bank's obligations as described below. For investment advisory services rendered to ISIS, BIMC is entitled to receive a quarterly fee of .05% (annually .20%) of ISIS' average net assets and .50% (annually 2.00%) of ISIS' gross income for such quarter. For the fiscal year ended December 31, 1998, BIMC received investment advisory fees of $119,712, which represents .36% of ISIS' average net assets during this period. Pursuant to the terms of ISIS' investment advisory agreement, and subject to the general supervision of the Board of Directors, BIMC is responsible for, makes decisions with respect to, and places orders for, all purchases and sales of ISIS' portfolio securities, and maintaining records relating to such purchases and sales. Pursuant to the investment advisory agreement, BIMC also serves as administrative agent for ISIS. BIMC maintains ISIS' financial accounts and records, prepares various returns and reports, and performs all other functions necessary to maintain its corporate existence and its relations with Shareholders, all at the request and subject to the supervision of ISIS' Board of Directors. These services are performed without additional cost to ISIS. Until June 18, 1998, PNC Bank, as sub-adviser to ISIS, provided investment research and credit analysis concerning prospective and existing fund investments, made recommendations with respect to ISIS' continuous investment program, recommended to BIMC the portion of ISIS' assets to be invested or held uninvested in cash or cash equivalents, supplied BIMC computer facilities and operating personnel, and provided certain statistical services. BIMC has assumed PNC Bank's 7 responsibilities under the sub-advisory agreement; BIMC's obligation to pay a fee to PNC Bank has been terminated; and the obligation of PNC Bank to provide facilities, personnel, services and to pay related expenses under the sub- advisory agreement were transferred to BIMC. Wilmington Trust Company ("WTC") serves as ISIS' custodian and automatic dividend investment plan agent. PFPC Inc. ("PFPC") serves as ISIS' transfer agent, registrar and dividend disbursing agent. Prior to December 31, 1998, PNC Bank served as ISIS' transfer agent, registrar and dividend disbursing agent. On December 31, 1998, PNC Bank assigned its rights and delegated its duties as transfer agent, registrar and dividend disbursing agent to PFPC. PFPC is an indirect, wholly-owned subsidiary of PNC Bank. For its services as transfer agent, PFPC is entitled to a fee payable at the rate of $0.4166 per month for each Shareholder account existing during such month, plus out-of-pocket expenses. Certain Arrangements with Service Providers -- the High Yield Bond Portfolio. BlackRock Advisors serves as the investment adviser and BFM serves as the sub-adviser for the High Yield Bond Portfolio. BlackRock Advisors and BFM are each indirect, majority-owned subsidiaries of PNC Bank. For its investment advisory services, BlackRock Advisors is entitled to fees computed daily and payable monthly at the maximum annual rate of .50% of the first $1 billion of average daily net assets, .45% of the next $1 billion of average daily not assets, .425% of the next $1 billion of average daily net assets, and .40% of average daily net assets over $3 billion. Out of these fees, BlackRock Advisors pays BFM a sub-advisory fee equal to .35% of the first $1 billion of average daily net assets, .30% of the next $1 billion of average daily net assets, .275% of the next $1 billion of average daily net assets, and .25% of average daily net assets over $3 billion. BlackRock Advisors has entered into an expense limitation agreement with BlackRock which requires BlackRock Advisors to waive or reimburse fees and expenses if operating expenses (which apply to expenses charged on Fund assets as a whole, but not expenses separately charged to the Series B Investor Shares) exceed .525% of average daily net assets. This expense limitation agreement continues until January 28, 2001. However, the High Yield Bond Portfolio may be required to repay such waived or reimbursed fees and expenses in the following two years if the repayments can be made within the expense limit noted above. For the fiscal year ended September 30, 1999, BlackRock Advisors received fees of $3,325, which represents .01% of the High Yield Bond Portfolio's average daily net assets during the period. Pursuant to the terms of the investment advisory agreement with BlackRock, BlackRock Advisors is responsible for the 8 overall investment management of the High Yield Bond Portfolio. BFM is responsible for the High Yield Bond Portfolio's day-to-day management and generally makes all buy and sell decisions. BFM also provides research and credit analysis. BlackRock Advisors and PFPC serve as co-administrators to BlackRock. Under the Administration Agreement, PFPC has agreed to: (i) maintain office facilities for BlackRock; (ii)furnish BlackRock with statistical and research data, clerical, accounting and bookkeeping services; (iii) provide and supervise the operation of an automated data processing system to process purchase and redemption orders; (iv) provide information and distribute written communications to shareholders; (v) handle shareholder problems and calls; (vi) research issues raised by financial intermediaries relating to investments in shares of any fund offered by BlackRock; (vii) review and provide advice with respect to communications for shares of any fund offered by BlackRock; (viii) monitor the investor programs that are offered in connection with shares of funds offered by BlackRock; (ix) provide oversight and related support services that are intended to ensure the delivery of quality services to the holders of shares of funds offered by BlackRock; and (x) provide certain other services required by BlackRock. Under the Administration Agreement, BlackRock Advisors is responsible for: (i) the supervision and coordination of BlackRock's service providers; (ii) the negotiation of service contracts and arrangements between BlackRock and its service providers; (iii) acting as a liaison between the trustees of BlackRock and BlackRock's service providers; and (iv) providing ongoing business management and support services in connection with BlackRock's operations. Pursuant to the terms of the Administration Agreement, BlackRock Advisors has delegated certain of its duties to BlackRock Distributors Inc. ("BDI"), the distributor for BlackRock. For their services as co-administrators, BlackRock Advisors and PFPC are entitled to receive fees computed daily and payable monthly at an aggregate annual rate of (i) .085% of the first $500 million of the High Yield Bond Portfolio's average daily net assets, .075% of the next $500 million of average daily net assets and .065% of the High Yield Bond Portfolio's average daily net assets in excess of $1 billion; and (ii) .145% of the first $500 million of average daily net assets allocated to the Series B Investor Shares of the High Yield Bond Portfolio, .135% of the next $500 million of such average daily net assets and 9 .125% of the average daily net assets of Series B Investor Shares of the High Yield Bond Portfolio in excess of $1 billion. PFPC also serves as the transfer agent and dividend disbursing agent for BlackRock. For its services in this capacity, PFPC is entitled to receive per account fees, with minimum annual fees of $24,000, plus disbursements, with respect to the Series B Investor Shares. Until further notice, transfer agency fees for Series B Investor Shares of the High Yield Bond Portfolio will not exceed the annual rate of .10% of the Series B Investor Shares' average daily net assets. PFPC Trust Company serves as the custodian to BlackRock. Prior to January 1, 1999, PNC Bank served as custodian to BlackRock. On January 1, 1999, PNC Bank assigned its rights and delegated its duties as custodian to PFPC Trust Company. PFPC Trust Company is an indirect, wholly-owned subsidiary of PNC Bank. For its services as custodian, PFPC Trust Company is entitled to receive fees at the rate of .015% of the first $500 million of average daily gross assets for Series B Investor Shares of the High Yield Bond Portfolio and .01% of the average daily gross assets in excess of $500 million. PFPC Trust Company is also entitled to out-of-pocket expenses and certain transaction charges. BDI serves as the distributor for BlackRock. BlackRock has adopted a distribution and service plan pursuant to Rule 12b- 1 under the 1940 Act which covers its Series B Investor Shares (the "BlackRock 12b-1 Plan"). Under the BlackRock 12b-1 Plan, Series B Investor Shares of the High Yield Bond Portfolio bear the expense of distribution and service fees payable to BDI, BlackRock Advisors or any other affiliate of PNC Bank at an annual rate of 1.15% of the average daily net assets attributable to such Series B Investor Shares. Of this amount, .75% represents distribution fees payable under the BlackRock 12b-1 Plan to BDI for distribution and Sales Support Services and affiliates of PNC Bank for sales support services provided in connection with the sale of Series B Investor Shares. This distribution fee may also be used by BDI and affiliates of PNC Bank to pay brokers, dealers, financial institutions and industry professionals (collectively, "Service Organizations") for sales support services and other related expenses. The remaining .40% represents shareholder service and shareholder processing fees. The service fee is .25% of average daily net assets and is paid to Service Organizations for the provision of general shareholder liaison services. The 10 shareholder processing fee is .15% of average daily net assets and is paid to Service Organizations for providing additional services to their clients who own Series B Investor Shares. Such additional services are intended to supplement the services provided to shareholders by the co-administrators or transfer agent. BlackRock Advisors determines the amount of shareholder service and shareholder processing fees paid to Service Organizations. BlackRock Advisors or any other affiliate of PNC Bank may serve as a Service Organization and receive fees under the BlackRock 12b-1 Plan. The BlackRock 12b-1 Plan is a "compensation" plan as opposed to a "reimbursement" plan. Accordingly, payments under the BlackRock 12b-1 Plan are based on a stated fee rather than on the specific amounts expended by BDI, BlackRock Advisors and BlackRock Advisors' affiliates for distribution and shareholder services. BDI, BlackRock Advisors and BlackRock Advisors' affiliates may be able to recover such amounts or may earn a profit from payments made by Series B Investor Shares of the High Yield Bond Portfolio under the BlackRock 12b-1 Plan. Comparative Fee and Expense Tables. The table below shows (i) information regarding the fees and expenses paid by ISIS during its most recent fiscal year, (ii) information regarding the fees and expenses paid by the High Yield Bond Portfolio's Series B Investor Shares during its most recent fiscal year, and (iii) estimated fees and expenses on a pro forma basis giving effect to the proposed Reorganization. The table indicates that total operating expenses for current ISIS Shareholders are going to significantly increase as a result of the Reorganization. 11 ------------------------------------------------------------------ The High Yield Bond Portfolio -- Series B Pro Forma ISIS Investor Shares Combined ---- ------------------ --------- SHAREHOLDER TRANSACTION EXPENSES (fees paid directly from your None None None investment) Maximum Sales Load Imposed on Purchases (as a percentage of offering price) Maximum Sales Load Imposed on None None None Reinvested Dividends (as a percentage of offering price) Contingent Deferred Sales None 4.50%/(1)/ 3.00%/(2)/ Charge (as a percentage of original purchase price or redemption proceeds, as applicable) Redemption Fee (as a None None None percentage of amount redeemed, if applicable) Exchange Fee None None None ------------------------------------------------------------------ ANNUAL FUND OPERATING EXPENSES (expenses that are deducted from Fund assets) (as a percentage of average net assets) Management Fees 0.36%/(3)/ 0.50% 0.50% Distribution and Service (12b-1) Fees 0.00% 1.15% 1.15% Interest Expenses 0.00% 0.39% 0.39% Other Expenses 0.40% 0.90%/(4)/ 0.90%/(4)/ ---- ---- ---- Total Annual Fund Operating Expenses 0.76% 2.94% 2.94% Fee Waivers and Expense Reimbursement 0.00% 0.63%/(5)/ 0.63%/(5)/ Net Expenses 0.76% 2.31%/(5)/ 2.31%/(5)/ ==== ==== ==== ----------------------------------------------------------------- _____________________________ (1) The Contingent Deferred Sales Charge ("CDSC") is 4.50% if shares are redeemed in less than one year. The CDSC for Series B Investor Shares decreases for redemptions made in subsequent years. After six years there is no CDSC on Series B Investor Shares. (2) Shareholders of ISIS will be given credit for a three year holding period for purposes of calculating the CDSC. See "Purchase, Redemption and Exchange Procedures." (3) ISIS pays BIMC a quarterly fee of .05% (annually .20%) of its average net assets and .50% (annually 2.00%) of the Fund's gross income for such quarter. (4) "Other Expenses" are based on estimated amounts for the current fiscal year. (5) BlackRock Advisors has contractually agreed to waive or reimburse fees or expenses in order to limit Fund expenses to 1.92% (excluding interest expense) of average daily net assets until January 28, 2001. The High Yield Bond Portfolio may have to repay some of these waivers and reimbursements to BlackRock Advisors in the following two years. 12 Example: This Example assumes that you invest $10,000 in the Funds for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that each Fund's operating expenses remain the same.

The ratio of operating expenses to average net assets of ISIS for the fiscal year ended December 31, 1998 was 0.76%. Expense Ratio -- Series B Investor Shares of The High Yield Bond Portfolio. The ratio of operating expenses to average net assets of Series B Investor Shares of the High Yield Bond Portfolio for the fiscal period ended September 30, 1999 was 1.92% (excluding interest expense), after waivers by BlackRock Advisors. Organization. ISIS is organized as a Maryland corporation and BlackRock is organized as a Massachusetts business trust. Purchase, Redemption and Exchange Procedures. ISIS' shares currently trade on The NASDAQ Small Cap Market/(SM)/ ("NASDAQ") and may only be purchased or sold through a broker or dealer at the current market price plus a brokerage commission. ISIS' shares have frequently traded at a discount from its net asset value. After the Reorganization, ISIS will no longer trade on the NASDAQ. If the Reorganization is approved by the Shareholders, any premium or discount existing on the date of such approval might be reduced prior to the date of the Reorganization to the extent purchasers of ISIS' shares in the open market are willing to pay less of a premium or accept less of a discount in anticipation of the Reorganization. There is no exchange privilege for shares of ISIS. Additional information concerning the trading of ISIS' shares on the NASDAQ is contained in Appendix C. Series B Investor Shares of the High Yield Bond Portfolio are offered to the public on a continuous basis at net asset value per share. There is no sales charge when you purchase Series B Investor Shares. Shareholders do pay a contingent deferred sales charge ("CDSC") when they redeem shares. The CDSC declines over six years from a high of 4.50% of the net assets redeemed. The CDSC is not charged under certain circumstances, including share exchanges and redemptions made in connection with certain retirement plans and in connection with certain shareholder services offered by BlackRock. After seven years, the Series B Investor Shares automatically convert to Series A Investor Shares, which have lower fees and no CDSC, as described more fully below. Series B Investor Shares may be redeemed through a shareholder's registered investment professional, who may charge for this service, or by sending a written redemption request to BlackRock Funds, c/o PFPC, P.O. Box 8907, Wilmington, DE 19899- 14 8907. BlackRock will redeem shares at the next net asset value calculated after the redemption request is received by PFPC minus any applicable CDSC. In connection with the Reorganization, Shareholders of ISIS will receive three years of holding period credit for purposes of calculating the CDSC and conversion to Series A Investor Shares with respect to the Series B Investor Shares received in the Reorganization. Accordingly, shareholders redeeming within one year of the Reorganization would be subjected to a 3.00% CDSC. After one year, the CDSC would decrease to 2.00%, and after two years the CDSC would decrease to 1.00%. There would be no CDSC after three years, and the Series B Investor Shares would automatically convert to Series A Investor Shares on the fourth anniversary of the Reorganization without any CDSC being charged. The conversion will take place at net asset value and, as a result, a shareholder will receive dollar-for-dollar the same value of Series A Investor Shares as the shareholder had of Series B Investor Shares. Because of this conversion feature, certain disclosures are necessary about Series A Investor Shares. Series A Investor Shares and Series B Investor Shares are both invested in the same portfolio of securities. These two classes differ in the fees and expenses charged to shareholders. Series A Investor Shares have no CDSC, but are subject to a front-end sales charge of 5.00%, which is subject to reduction for certain large purchases. No front-end sales charge will be charged on the conversion from Series B Investor Shares to Series A Investor Shares. In addition, the distribution and service fees charged to Series A Investor Shares are lower than those charged to Series B Investor Shares. Series A Investor Shares bear distribution and service fees at an annual rate of .50% of the average daily net assets of such shares. Of this amount, .10% represents distribution fees payable under the BlackRock 12b-1 Plan. The remaining .40% represents shareholder service and shareholder processing fees identical to those paid on Series B Investor Shares. After the Reorganization, shareholders may exchange their shares received in the Reorganization for other Series B Investor Shares of funds offered by BlackRock. 15 Dividends, Distributions and Pricing. Shareholders of ISIS and the High Yield Bond Portfolio are entitled to dividends and distributions declared from the net investment income and net realized gains, if any, earned on investments in each Fund's investment portfolio. ISIS and the High Yield Bond Portfolio each distributes its net investment income monthly and distributes its net realized capital gains, if any, at least annually. Dividends and distributions are paid to Shareholders of ISIS in cash unless they have elected to participate in the Automatic Dividend Investment Plan (the "DRIP"). Pursuant to the DRIP, the reinvestment of dividends and distributions in additional shares of ISIS are made at the lower of net asset value or market value (but not less than 95% of market value). Dividends and distributions of the High Yield Bond Portfolio are automatically reinvested in additional shares at net asset value unless PFPC, the Fund's transfer agent, is instructed in writing to pay such dividends and distributions in cash. The net asset value per share of ISIS is determined once a week, on the last business day of the week, and on the last business day of the month. The net asset value per share of the High Yield Bond Portfolio is determined each day that the New York Stock Exchange is open, at 4:00 p.m. Eastern time. Voting Information. This Combined Prospectus/Proxy Statement is being furnished in connection with the solicitation of proxies by ISIS' Board of Directors for use at the Meeting. Only Shareholders of record at the close of business on February _____, 2000 will be entitled to vote at the Meeting or any adjournment thereof. Shares represented by a properly executed proxy will be voted in accordance with the instructions thereon or if no specification is made, the persons named as proxies will vote in favor of the proposal set forth in the Notice of Meeting. Proxies may be revoked at any time before they are exercised by the subsequent execution and submission of a revised proxy, by written notice of revocation to ISIS, or by voting in person at the Meeting. RISK FACTORS The following discussion highlights the principal risk factors associated with an investment in ISIS and the High Yield Bond Portfolio and is qualified in its entirety by the more extensive discussion of risk factors set forth below under 16 "Comparison of Investment Policies and Risk Factors" and in the Prospectus and Statement of Additional Information of the High Yield Bond Portfolio, which are incorporated herein by reference. Each Fund seeks to achieve its investment objective through investments in debt securities. The investment adviser for each Fund attempts to choose debt securities that may provide above average current income, however, there is no guarantee that shares of each Fund will not lose value. The market value of securities held by the Funds is expected to vary according to, among other factors, changes in prevailing interest rates. The variation tends to be greater for portfolios with longer average weighted maturities. In general, if interest rates increase from the time a fixed income security is purchased, the market value of that security will decline. Similarly, if interest rates decrease from the time a fixed income security is purchased, the market value of that security is likely to increase. Each Fund is also subject to call risk, credit risk and event risk. Call risk is the possibility that during periods of falling interest rates, certain debt securities with high interest rates may be pre-paid (or "called") by the issuers prior to maturity. This may cause a Fund's average weighted maturity to fluctuate, and may require a Fund to invest the resulting proceeds at lower interest rates. Credit risk refers to the possibility that the issuer of the bond will not be able to make principal and interest payments. Event risk is the possibility that securities may suffer declines in credit quality and market value due to issuer restructuring or other factors. Each Fund's ability to invest in debt securities rated below investment grade (i.e., rated lower than Baa by Moody's Investor Services, Inc. or rated lower than BBB by Standard & Poor's Ratings Group and Fitch-IBCA, Inc.) also involves risk. Lower-rated securities will usually offer higher yields than investment grade securities. However, there is more risk associated with these investments because of reduced creditworthiness and increased risk of default. In addition, the market values of certain lower-rated debt securities tend to reflect specific developments with respect to the issuer to a greater extent then do higher rated securities, which react primarily to fluctuations in the general level of interest rates, and tend to be more sensitive to economic conditions than higher rated securities. Issuers of lower-rated debt securities often are highly leveraged and may not have available to them more traditional methods of financing. 17 Securities rated below BBB or Baa by a rating agency are characterized by the rating agencies as predominantly speculative; the future of the issuers cannot be considered as well assured, and often the protection of interest and principal payments may be very moderate and may face major ongoing uncertainties or exposure to adverse business, financial or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. Factors adversely affecting the market price and yield of lower-rated securities, will adversely affect a Fund's net asset value. In addition, the retail secondary market for these securities may be less liquid than that for higher rated securities; adverse conditions could make it difficult at times for a Fund to sell certain securities or could result in lower prices than those used in calculating its net asset value. Like other investment companies, financial and business organizations and individuals around the world, the Funds could be adversely affected if the computer systems used by BIMC, BlackRock Advisors and the Funds' other service providers, and by persons with whom they have transactions, do not properly process and calculate date-related information and data from and after January 1, 2000. This is commonly known as the "Year 2000 Problem." BIMC and BlackRock Advisors are taking steps to solve the Year 2000 Problem with respect to the computer systems that they use before January 1, 2000 and are working with the Funds' other major service providers to determine their systems' ability to handle Year 2000 problems. At this time, however, there can be no assurance that these steps will be sufficient to avoid any adverse impact on a Fund as a result of the Year 2000 Problem. Year 2000 problems may also hurt issuers whose securities the Funds hold or security markets in general There is no assurance that either Fund will achieve its investment objective. INFORMATION RELATING TO THE PROPOSED REORGANIZATION The terms and conditions under which the Reorganization may be consummated are set forth in the Reorganization Agreement. Significant provisions of the Reorganization Agreement are summarized below; however, this summary is qualified in its entirety by reference to the Reorganization Agreement, a copy of which is attached as Appendix A to this Combined Prospectus/Proxy Statement and which is incorporated herein by reference. 18 Description of the Reorganization Agreement. The Reorganization Agreement provides that at the Effective Time of the Reorganization (as defined in Article VIII of the Reorganization Agreement), the assets and liabilities of ISIS will be transferred to and assumed by the High Yield Bond Portfolio. In exchange for the transfer of the assets of, and the assumption of the liabilities of ISIS, BlackRock will issue at the Effective Time of the Reorganization full and fractional Series B Investor Shares of the High Yield Bond Portfolio equal in aggregate dollar value to the aggregate net assest value of full and fractional outstanding shares of ISIS as determined at the valuation time specified in the Reorganization Agreement. The Reorganization Agreement provides that ISIS will declare a dividend or dividends prior to the Effective Time of the Reorganization which, together with all previous dividends, will have the effect of distributing to the Shareholders of ISIS all undistributed net investment income earned and net capital gains realized up to and including the Effective Time of the Reorganization. Following the transfer of assets to, and the assumption of the liabilities of ISIS by, the High Yield Bond Portfolio, ISIS will distribute the Series B Investor Shares of the High Yield Bond Portfolio received from BlackRock to the Shareholders of ISIS in liquidation of ISIS. Each Shareholder of ISIS at the Effective Time of the Reorganization will receive an amount of Series B Investor Shares with a total net asset value equal to the net asset value of their shares of common stock of ISIS, plus the right to receive any dividends or distributions which were declared before the Effective Time of the Reorganization but that remained unpaid at that time with respect to the shares of ISIS. Following the Reorganization, the registration of ISIS as an investment company under the 1940 Act will be terminated, and ISIS will be dissolved under state law. Approval of the Reorganization Agreement shall constitute the approval of a change in ISIS' by-laws and its fundamental limitations which may be deemed to prevent ISIS from taking the actions necessary to effectuate the Reorganization. The change is: Current Proposed ------- -------- The Fund may not purchase This limitation/by-law would be securities of other investment restated as follows: companies except by purchase of 19 Current Proposed ------- -------- securities of closed-end The Fund may not acquire any companies in the open market other investment company or involving only customary investment company security broker's commissions or except in connection with a acquisition of such securities merger, consolidation, as part of a merger, reorganization, sale or acquisition consolidation, reorganization of assets or where otherwise or purchase of assets approved permitted by the Investment by the Fund's shareholders, if Company Act of 1940. required by law. After the Reorganization all of the issued and outstanding shares of ISIS shall be cancelled on the books of ISIS and the stock transfer books of ISIS will be permanently closed. The Reorganization is subject to a number of conditions, including without limitation approval of the Reorganization Agreement and the transactions contemplated thereby described in this Combined Prospectus/Proxy Statement by the Shareholders of ISIS; the receipt of certain legal opinions described in the Reorganization Agreement (which include an opinion of Ropes & Gray that the shares of the High Yield Bond Portfolio issued to Shareholders of ISIS in accordance with the terms of the Reorganization Agreement will be validly issued, fully paid and non-assessable); the receipt of certain certificates from the parties concerning the continuing accuracy of the representations and warranties in the Reorganization Agreement and other matters; and the parties' performance in all material respects of their respective agreements and undertakings in the Reorganization Agreement. Assuming satisfaction of the conditions in the Reorganization Agreement, the Effective Time of the Reorganization will be on March _______, 2000 or such other date as is agreed to by the parties, provided, however, that unless an officer of BlackRock and ISIS determine otherwise, the Effective Time of the Reorganization shall not occur until the period has run for any objecting Shareholder of ISIS to make a written demand for payment for his or her stock pursuant to the Maryland General Corporation Law, as described more fully below under "Information Relating to Voting Matters - Appraisal Rights." The expenses of ISIS and BlackRock in connection with the Reorganization will be borne by BIMC. 20 The Reorganization Agreement and the Reorganization described herein may be abandoned at any time prior to the Effective Time of the Reorganization by the mutual consent of the parties to the Reorganization Agreement. The Reorganization Agreement provides further that at any time prior to or (to the fullest extent permitted by law) after approval of the Reorganization Agreement by the Shareholders of ISIS (a) the parties thereto may, by written agreement authorized by their respective Boards or executive officers, and with or without the approval of their respective shareholders, amend any of the provisions of the Reorganization Agreement and (b) any party may waive any breach by the other party or the failure to satisfy any of the conditions to its obligations (such waiver to be in writing and authorized by an officer of the waiving party with or without the approval of such party's shareholders). Board Considerations. In its consideration and approval of the Reorganization at meetings held on March 12, 1999, May 20, 1999, June 23, 1999, September 9, 1999 and October 12, 1999, the Board of Directors of ISIS considered and discussed the future of ISIS and how to best serve the Shareholders' interests. The directors discussed the size of ISIS' investment portfolio (approximately $31.3 million as of September 30, 1999) and the increasing difficulty in maintaining a high current rate of dividend income. The Board discussed ISIS' concentration in utility securities and changes affecting the utilities industry. They discussed proposed changes to general accounting rules which would change the way ISIS amortizes and/or accretes the premiums and discounts on portfolio securities, and the impact of such changes on the Fund's dividend income. The Board of Directors employed an independent consultant to review ISIS' present operations. The directors and the independent consultant reviewed proposals to: modify the Fund's investment policies to change it into a non-investment grade portfolio; liquidate the assets; increase assets through a private placement or a rights offering; change investment advisers; convert ISIS to an open-end fund; merge ISIS with other closed-end investment companies; and merge ISIS into a fund of BlackRock. After discussions, it was decided to pursue the Reorganization with the High Yield Bond Portfolio. In considering the High Yield Bond Portfolio as opposed to an investment grade investment portfolio offered by BlackRock, the Board of Directors reviewed the history of ISIS, noting that the Fund has traditionally been an income-producing investment for its Shareholders, and that the High Yield Bond Portfolio was probably a more likely investment vehicle to sustain the 21 competitive dividend level. The directors did consider, however, that investments in high yield securities involve greater risks than investments in investment grade securities. The directors noted that Shareholders wishing an investment grade bond fund would be able to exchange into such a fund of BlackRock without being charged a CDSC. Such an exchange would be, however, a taxable event. With regard to the CDSC, it was noted that ISIS has frequently traded on the NASDAQ at a discount to its net asset value. The Board also considered that as shareholders of the High Yield Bond Portfolio, ISIS' Shareholders could redeem their Series B Investor Shares at net asset value and pay a 3.00% CDCS (or less in later years) upon redemption. Currently, ISIS' Shareholders have to sell shares at current market value, which has frequently been less than net asset value, and pay brokerage commissions. The directors also considered the fee structure of the Series B Investor Shares of the High Yield Bond Portfolio, noting that total operating expenses were higher than those of ISIS. They also considered the fact that BlackRock Advisors and its affiliates may benefit from these increased fees. In its consideration and approval of the Reorganization, the Board of Directors of ISIS considered, among other things: the terms of the Reorganization Agreement; a comparison of each Fund's historical and projected expense ratios; the comparative investment performance of the Funds; the effect of such Reorganization on ISIS and its Shareholders; the fact that the day-to-day portfolio management would be unchanged by the Reorganization; the investment advisory services supplied by BlackRock Advisors; the management and other fees payable by the High Yield Bond Portfolio; the similarities and differences of the investment objective and policies of the Funds; the opportunity to combine ISIS and the High Yield Bond Portfolio into a single, larger asset base; the recommendations of BIMC and BlackRock Advisors with respect to the proposed Reorganization; the fact that the Reorganization would constitute a tax-free reorganization; the determination that the proposed Reorganization is in the best interests of the shareholders and the fact that the interests of Shareholders would not be diluted as a result of the Reorganization. After considering the foregoing factors, together with such other information as they believed to be relevant, the Board of Directors of ISIS approved the Reorganization Agreement and directed that it be submitted to Shareholders for approval. 22 THE BOARD OF DIRECTORS OF ISIS RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" APPROVAL OF THE REORGANIZATION AGREEMENT. The Board of Directors of ISIS has not determined what action ISIS will take in the event Shareholders fail to approve the Reorganization Agreement or for any reason the Reorganization is not consummated. In either such event, the Board will consider other appropriate courses of action, including the sale of assets to, or merger with, another investment company, the possible liquidation of ISIS, or continuing the operations of ISIS in its present form. Similarly, at meetings held on August 11, 1999 and October 4, 1999, the Board of Trustees of BlackRock considered the proposed Reorganization. Based upon its evaluation of the relevant information provided to it, and in light of its fiduciary duties under federal and state law, the Board of Trustees determined that (i) the proposed Reorganization is in the best interests of the shareholders of the High Yield Bond Portfolio and (ii) the interests of the High Yield Bond Portfolio's shareholders would not be diluted as a result of the Reorganization. Federal Income Tax Consequences. Consummation of the Reorganization is subject to the condition that ISIS and BlackRock receive an opinion from Drinker Biddle & Reath LLP to the effect that for federal income tax purposes: (i) the transfer of all of the assets and liabilities of ISIS to the High Yield Bond Portfolio in exchange for Series B Investor Shares of the High Yield Bond Portfolio and the liquidating distributions to Shareholders of Series B Investor Shares of the High Yield Bond Portfolio so received, as described in the Reorganization Agreement, will constitute a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"), and with respect to the Reorganization, ISIS and the High Yield Bond Portfolio will each be considered "a party to a reorganization" within the meaning of 368(b) of the Code; (ii) no gain or loss will be recognized by ISIS as a result of such transaction; (iii) no gain or loss will be recognized by the High Yield Bond Portfolio as a result of such transaction; (iv) no gain or loss will be recognized by the Shareholders of ISIS on the distribution to such Shareholders of Series B Investor Shares of the High Yield Bond Portfolio in exchange for their shares of ISIS; (v) the aggregate basis of Series B Investor Shares of the High Yield Bond Portfolio received by a Shareholder of ISIS will be the 23 same as the aggregate basis of the Shareholder's shares of ISIS immediately prior to the Reorganization; (vi) the basis of the High Yield Bond Portfolio in the assets of ISIS received pursuant to such transaction will be the same as the basis of such assets in the hands of ISIS immediately before such transaction; (vii) a Shareholder's holding period for Series B Investor Shares of the High Yield Bond Portfolio will be determined by including the period for which the Shareholder held ISIS shares exchanged therefor, provided that the Shareholder held such shares in ISIS as a capital asset; and (viii) the High Yield Bond Portfolio's holding period with respect to the assets received in the Reorganization will include the period for which such assets were held by ISIS. BlackRock and ISIS have not sought a tax ruling from the Internal Revenue Service ("IRS"), but are acting in reliance upon the opinion of counsel discussed in the previous paragraph. That opinion is not binding on the IRS and does not preclude the IRS from adopting a contrary position. Shareholders should consult their own advisers concerning the potential tax consequences to them, including state and local income taxes. Capitalization. Because ISIS will be combined with the High Yield Bond Portfolio in the Reorganization, the total capitalization of the High Yield Bond Portfolio after the Reorganization is expected to be greater than the current capitalization of ISIS. The following table sets forth as of September 30, 1999: (i) the capitalization of ISIS; (ii) the capitalization of the High Yield Bond Portfolio; and (iii) the pro forma capitalization of the High Yield Bond Portfolio as adjusted to give effect to the proposed Reorganization. There is, of course, no assurance that the Reorganization will be consummated. Moreover, if consummated, the capitalizations of the High Yield Bond Portfolio and ISIS are likely to be different at the Effective Time of the Reorganization as a result of fluctuations in the value of portfolio securities of both Funds and daily share purchase and redemption activity in the High Yield Bond Portfolio. 24 ================================================================================ The High Yield Bond Pro Forma ------------------- ISIS Portfolio Combined ---- --------- -------- - -------------------------------------------------------------------------------- Total Net Assets ($) 31,274,404 83,325,011 114,599,415 - -------------------------------------------------------------------------------- Shares Outstanding 1,822,752 1,274,781 (Series B 4,489,005 (Series B Investor shares) Investor Shares) - -------------------------------------------------------------------------------- Net Asset Value Per 17.16 9.73 (Series B 9.73 (Series B Share ($) Investor Shares) Investor Shares) ================================================================================ COMPARISON OF INVESTMENT POLICIES AND RISK FACTORS The following discussion summarizes some of the similarities and differences in the investment policies and risk factors of the Funds, and is qualified in its entirety by the discussion in the Prospectus and Statement of Additional Information of the High Yield Bond Portfolio, which are incorporated herein by reference. The investment objective of ISIS is to seek as high a level of current income as is consistent with prudent investment. The investment objective of the High Yield Bond Portfolio is to seek current income by investing primarily in non-investment grade bonds. The investment objective of ISIS is fundamental, meaning that it may not be changed without the affirmative vote of the holders of a majority of its outstanding shares, as defined in the 1940 Act. The investment objective of the High Yield Bond Portfolio is not fundamental and may be changed by its Board of Trustees without shareholder approval, although shareholders will be given 30 days' notice of any such change. General. Both Funds invest in debt securities. The High Yield Bond Portfolio invests primarily in non-investment grade bonds (i.e., rated lower than Baa by Moody's Investor Services, Inc. or rated lower than BBB by Standard & Poor's Ratings Group and Fitch-IBCA, Inc.) in the ten to fifteen year maturity range. The High Yield Bond Portfolio normally invests at least 80% of its total assets in bonds or convertible securities and at least 65% of its total assets in non-investment grade (i.e., junk) bonds. The High Yield Bond Portfolio may invest up to 10% of its total assets in bonds of foreign issuers. 25 ISIS must invest at least 60% of its assets in: (1) marketable straight debt securities which are rated at the time of purchase within the four highest grades assigned by Moody's Investors Service, Inc. (Aaa, Aa, A or Baa), Standard & Poor's Ratings Group, Division of McGraw Hill (AAA, AA, A or BBB) or Fitch IBCA, Inc. (AAA, AA, A or BBB); (2) securities of, or guaranteed by, the United States government, its agencies or instrumentalities; (3) securities (payable in U.S. dollars) of, or guaranteed by, the government of Canada or of a Province of Canada under circumstances that would not subject the Fund to payment of U.S. Interest Equalization Tax; (4) commercial paper of companies having, at the time of purchase, an issue of outstanding debt securities rated as described in (1) above; and (5) cash or cash equivalents. ISIS is permitted to invest up to 40% of its assets in non-investment grade securities. ISIS is required to invest at least 25% of its assets in the securities of utility companies. A principal difference in investment policies is that ISIS invests primarily in investment grade securities while the High Yield Bond Portfolio invests primarily in non-investment grade securities. Another principal difference is the range of securities and investment techniques available to the High Yield Bond Portfolio. The following summarizes those investment policies and compares them to ISIS' policies. The High Yield Bond Portfolio can invest in a wide range of securities including mezzanine investments, collateralized bond obligations ("CBOs"), bank loans, and mortgage-backed and asset-backed securities. ISIS does not have a stated policy to invest in these types of securities; however, it has no investment policy or limitation which would prohibit investments in these securities. The High Yield Bond Portfolio may invest in mezzanine investments. Mezzanine investments are subordinated debt securities which receive payments of interest and principal after other more senior security holders are paid. They are generally issued in private placements in connection with an equity security. Mezzanine securities carry the risk that the issuer will not be able to meet its obligations and that the equity securities purchased with the mezzanine investments may lose value. The High Yield Bond Portfolio may invest in CBOs, which are securities backed by a diversified pool of high yield securities. The pool of high yield securities underlying CBOs 26 is typically separated into groupings, called tranches, representing different degrees of credit quality. The higher quality tranches have greater degrees of protection and pay lower interest rates. The lower tranches, with greater risk, pay higher interest rates. The High Yield Bond Portfolio may invest in bank loans. Bank loans are fixed and floating rate loans arranged through private negotiations between a company or a foreign government and one or more financial institutions. The Fund considers such investments to be debt securities. The market for bank loans may not be highly liquid and the Fund may have difficulty selling them. These investments expose a fund to the risk of investing in both the financial institution and the underlying borrower. The High Yield Bond Portfolio may make investments in residential and commercial mortgage-backed securities ("CMBS")and other asset-backed securities. CMBS are bonds that are backed by a mortgage loan or pool of loans secured by commercial property, not residential mortgages. Asset-backed securities are bonds that are backed by a pool of assets, usually loans such as installment sale contracts or credit card receivables. The characteristics of these mortgage-backed and asset-backed securities differ from traditional fixed income securities. A main difference is that the principal on mortgage- or asset-backed securities may normally be prepaid at any time, which will reduce the yield and market value of these securities. Asset-backed securities and CMBS generally experience less prepayment than residential mortgage-backed securities. In periods of falling interest rates, the rate of prepayments tends to increase (as does price fluctuation) as borrowers are motivated to pay off debt and refinance at new lower rates. During such periods, reinvestment of the prepayment proceeds by the investment adviser will generally be at lower rates of return than the return on the assets which were prepaid. Certain commercial mortgage-backed securities are issued in several classes with different levels of yield and credit protection. The High Yield Bond Portfolio's investments in commercial mortgage-backed securities with several classes will normally be in the lower classes that have less credit protection. Certain asset-backed securities are based on loans that are unsecured, which means that there is no collateral to seize if 27 the underlying borrower defaults. Other asset-backed securities may not have the benefit of as much collateral as mortgage-backed securities. The High Yield Bond Portfolio may, when consistent with the Fund's investment objective, use options or futures (commonly known as derivatives). The primary purpose of using derivatives is to attempt to reduce risk to the Fund as a whole (i.e., to hedge) but they also may be used to maintain liquidity, commit cash pending investment or to increase returns. The High Yield Bond Portfolio may also enter into interest rate or foreign currency transactions as a hedging technique. In these transactions, the Fund exchanges its right to pay or receive interest or currencies with another party for their right to pay or receive interest or another currency in the future. ISIS does not have a stated policy to invest in these types of securities; however, it has no investment policy or limitation which would prohibit investments in these securities. The High Yield Bond Portfolio's use of derivatives, interest rate and foreign currency transactions may reduce its returns and/or increase volatility, which is defined as the characteristic of a security or a market to fluctuate significantly in price within a short period of time. The High Yield Bond Portfolio may invest up to 10% of its total assets in bonds of foreign issuers. ISIS has no explicit investment policy or limitation concerning investments in foreign issuers. Foreign securities involve risks not typically associated with investing in U.S. securities. These risks include but are not limited to: currency risks (the risk that the value of interest paid on foreign securities, or the value of the securities themselves, may fall if currency exchange rates change), the risk that a security's value will be hurt by changes in foreign political or social conditions, the possibility of heavy taxation or expropriation and more difficulty obtaining information on foreign securities or companies. In addition, a portfolio of foreign securities may be harder to sell and may be subject to wider price movements than comparable investments in U.S. companies. There is also less government regulation of foreign securities markets. In addition, political and economic structures in developing countries may be undergoing rapid change and these countries may lack the social, political and economic stability of more developed countries. As a result some of the risks described above, including the risks of nationalization or expropriation of assets and the existence of smaller, more 28 volatile and less regulated markets, may be increased. The value of many investments in emerging market countries recently has dropped significantly due to economic and political turmoil in many of these countries. On January 1, 1999, eleven European countries implemented a new currency unit called the "Euro" which is expected to reshape financial markets, banking systems and monetary policies in Europe and other parts of the world. While it is impossible to predict the impact of the "Euro," it is possible that it could increase volatility in financial markets worldwide which could hurt the value of shares of the High Yield Bond Portfolio. The High Yield Bond Portfolio may invest in securities rated as low as "C." These securities are very risky and have uncertainties regarding the issuer's ability to make interest and principal payments. As stated above, ISIS can invest up to 40% of its assets in securities rated below investment grade, including securities rated "C." ISIS has no explicit limitation on what ratings are acceptable. Accordingly, ISIS could invest in securities rated "C" or below. Each Fund can borrow money to buy additional securities. This practice is known as "leverage." The High Yield Bond Portfolio may borrow from banks or other financial institutions or through reverse repurchase agreements (under which the Fund sells securities and agrees to buy them back at a particular date and price). The High Yield Bond Portfolio currently may borrow up to 33-1/3% of the value of its total assets, and may borrow an additional 5% of its total assets for temporary purposes. ISIS also may borrow money to purchase securities. ISIS currently may borrow up to 25% of the value of its total assets. ISIS also may borrow money from banks for temporary or emergency purposes. Leverage is a speculative technique which may expose a Fund to greater risk and increase its costs. Increases and decreases in the value of a Fund's portfolio will be magnified when the Fund uses leverage. A Fund will also have to pay interest on its borrowings, reducing return. The High Yield Bond Portfolio may lend some of its securities on a short- term basis in order to earn extra income. The High Yield Bond Portfolio will receive collateral in cash or high quality securities equal to the current value of the loaned securities. These loans will be limited to 33-1/3% of the value of the Fund's total assets. Securities loans involve the risk of a delay in receiving additional collateral if the value of the securities goes up while they are on loan. There is also 29 the risk of delay in recovering the loaned securities and of losing rights to the collateral if a borrower goes bankrupt. ISIS may also lend securities. These loans are limited to 20% of the value of its total assets. Investment Limitations. Neither ISIS nor the High Yield Bond Portfolio may change their fundamental investment limitations without the affirmative vote of a majority of the outstanding shares, as defined in the 1940 Act. The following discusses the similarities and differences in their fundamental limitations. Each Fund is a diversified investment portfolio and, therefore, has a fundamental policy limiting investments in securities of any one issuer to 5% of total assets and excludes securities issued or guaranteed by the U.S. Government, its agencies, enterprises or instrumentalities. This limitation applies to 100% of ISIS' total assets. This limitation only applies to 75% of the High Yield Bond Portfolio's total assets. Consequently, up to 25% of the High Yield Bond Portfolio's total assets may be invested without regard to this 5% limitation. Neither Fund will invest more than 25% of its total assets in the securities of issuers in any one industry, except that, as stated above, ISIS is required to invest at least 25% of its total assets in securities of utility companies. Neither Fund will make loans, except that: (a) each may purchase or hold certain debt instruments and engage in repurchase agreements; and (b) each may lend portfolio securities as described above. Neither Fund will issue senior securities, except that: (a) each may borrow money for temporary or emergency purposes up to 5% of total assets; and (b) each may borrow money to purchase additional securities as described above. Neither Fund may purchase or sell real estate, except that the Funds may purchase securities of issuers which deal in real estate and may purchase securities which are secured by interests in real estate. The High Yield Bond Portfolio may not acquire any other investment company or investment company security except in connection with a merger, consolidation, reorganization or acquisition of assets or where otherwise permitted by the 1940 Act. ISIS is only permitted to purchase shares of other closed- 30 end funds in the open market involving only customary broker's commissions or acquire shares of other investment companies in connection with a merger, consolidation, reorganization or purchase of assets approved by the Fund's Shareholders, if required by law. However, as described above under "Information Relating to the Proposed Reorganization - Description of the Reorganization Agreement," approval of the Reorganization Agreement will constitute the approval of a change to this limitation which will make it substantially the same as the High Yield Bond Portfolio's limitation. Neither Fund will act as an underwriter of securities within the meaning of the Securities Act of 1933 except to the extent that the purchase of obligations directly from the issuer thereof, or the disposition of securities, may be deemed to be an underwriting. Neither Fund may purchase securities of companies for the purpose of exercising control. Neither Fund may purchase or sell commodities or commodity contracts. The High Yield Bond Portfolio may, however, invest in companies engaging in whole or in part in such activities. Additionally, the High Yield Bond Portfolio does not consider currency contracts, futures contracts and related options to be covered by this limitation. Neither Fund may purchase securities on margin, make short sales or maintain a short position. However, the High Yield Bond Portfolio does not consider futures contracts and related options to be covered by this limitation. In addition, the High Yield Bond Portfolio would be allowed to sell a security short-against-the-box. The following fundamental limitations of the High Yield Bond Portfolio have no counterpart in ISIS. The High Yield Bond Portfolio may not: write or sell put options, call options, straddles, spreads, or any combination thereof, except for transactions in options on securities, securities indices, futures contracts and options thereon; or invest in oil, gas or mineral exploration or development programs, but may invest in companies engaged in whole or in part in such activities. See "Additional Investment Limitations" in the High Yield Bond Portfolio's Statement of Additional Information which is incorporated by reference herein for the complete list of fundamental investment limitations. 31 Other Information.

ISIS is organized as a Maryland corporation and is subject to the provisions of its Articles of Incorporation and By-laws. BlackRock is organized as a Massachusetts business trust and is subject to the provisions of its Declaration of Trust and Amended and Restated Code of Regulations. Shares of both ISIS and BlackRock: (i) are entitled to one vote for each full share held and a proportionate fractional vote for each fractional share held; and (ii) are entitled to participate equally in the dividends and distributions that are declared with respect to a particular investment portfolio and in the net distributable assets of such portfolio on liquidation.

Shareholders may obtain copies of the Articles of Incorporation and By-laws of ISIS and the Declaration of Trust and Amended and Restated Code of Regulations of BlackRock upon written request at the addresses shown on the cover page of this Combined Prospectus/Proxy Statement. 32 INFORMATION RELATING TO VOTING MATTERS General Information. This Combined Prospectus/Proxy Statement is being furnished in connection with the solicitation of proxies by the Board of Directors of ISIS for use at the Meeting. It is expected that the solicitation of proxies will be primarily by mail. ISIS' officers and service providers may also solicit proxies by telephone, facsimile machine, telegraph or personal interview. In addition, although it has not done so to date, ISIS may retain the services of one or more outside organizations to aid in the solicitation of proxies. Such organizations normally charge a fee plus out-of-pocket expenses. Any Shareholder giving a proxy may revoke it at any time before it is exercised by submitting to ISIS a written notice of revocation or a subsequently executed proxy or by attending the Meeting and electing to vote in person. Only Shareholders of record at the close of business on February __, 2000 will be entitled to vote at the Meeting. On that date, there were outstanding and entitled to be voted _________ shares. Each share or fraction thereof is entitled to one vote or fraction thereof. If the accompanying proxy is executed and returned in time for the Meeting, the shares covered thereby will be voted in accordance with the proxy on all matters that may properly come before the meeting (or any adjournment thereof). Shareholder and Board Approvals. Approval of the Reorganization Agreement (and the transactions contemplated thereby) requires the affirmative vote of at least a majority of the outstanding shares of ISIS. In tallying Shareholder votes, abstentions and broker non-votes (i.e., proxies sent in by brokers and other nominees that cannot be voted on a proposal because instructions have not been received from the beneficial owners) will be counted for purposes of determining whether or not a quorum is present for purposes of convening the Meeting. On the Reorganization proposal, abstentions and broker non-votes will be considered to be a vote against the Reorganization proposal. The approval of the Reorganization by the shareholders of the High Yield Bond Portfolio is not being solicited because their approval or consent is not legally required. 33 At February __, 2000, the directors and officers of ISIS as a group owned ____% of the outstanding shares of ISIS. At February __, 2000, the name, address and percentage ownership of the persons who owned beneficially more than 5% of the outstanding shares of ISIS and the percentage of Series B Investor Shares of the High Yield Bond Portfolio that would be owned by such persons upon consummation of the Reorganization based upon their holdings at February __, 2000 are as follows: ================================================================================ Percentage of ISIS Percentage of Series B Name and Amount of Shares Shares Owned on Investor Shares of the Address Owned Record Date High Yield Bond ------- ----- ----------- Portfolio Owned Upon Consummation ------------ - -------------------------------------------------------------------------------- ISIS ================================================================================ At February __, 2000, the trustees and officers of BlackRock as a group owned less than 1% of the outstanding shares of the High Yield Bond Portfolio. At February __, 2000, the name, address and share ownership of the persons who owned beneficially more than 5% of any class of the High Yield Bond Portfolio and the percentage of shares that would be owned by such person upon consummation of the Reorganization based upon their holdings at February __, 2000 were as follows: =================================================================================================================== Percentage of Fund Percentage of Percentage of Shares Class Owned The High Yield Name and Class and Amount Class Owned on Owned on Upon Bond Portfolio Address of Shares Owned Record Date Record Date Consummation - -------------- ------- --------------- ----------- ----------- ------------ - ------------------------------------------------------------------------------------------------------------------- - ------------------------------------------------------------------------------------------------------------------- =================================================================================================================== Appraisal Rights. Under the Maryland General Corporation Law, certain relevant sections of which are attached to this Combined Prospectus/Proxy Statement as Appendix D, each Shareholder of ISIS will be entitled to demand and receive payment of the "fair value" of his or her shares in cash, if he or she (i) prior to or at the Meeting, files with ISIS a written objection to the Reorganization, (ii) does not vote in favor of the Reorganization by person or by proxy and (iii) within 20 days after the Articles of Transfer with respect to the Reorganization have been accepted for record by the Maryland State Department of Assessments and Taxation (the "Maryland 34 SDAT") makes a written demand on BlackRock for payment of his or her shares (a "Payment Demand"), stating the number of shares for which payment is demanded. A Payment Demand should be sent to BlackRock at Bellevue Park Corporate Center, 400 Bellevue Parkway, Wilmington, Delaware 19809, Attn: Brian P. Kindelan, Secretary. Any Shareholder of ISIS who fails to comply with the requirements described above will be bound by the terms of the Reorganization. Under the Maryland General Corporation Law, "fair value" would be determined as of the close of business on the day that the Shareholders vote on the Reorganization and would not include any appreciation or depreciation that results, directly or indirectly, from the Reorganization or from its proposal. Moreover, in that regard, a Shareholder who makes a Payment Demand for his or her shares would not be entitled to receive any of the dividends or distributions that will be payable to Shareholders of record of those shares on a record date that is after the close of business on the day the Shareholders vote on the Reorganization. BlackRock will promptly deliver or send by certified mail, return receipt requested, to each Shareholder of ISIS who has filed a written objection to the proposed Reorganization with BlackRock, written notice of the date of acceptance of the Articles of Transfer with respect to the Reorganization for record by the Maryland SDAT and of the Effective Time of the Reorganization. Such notice may include a written offer by BlackRock to pay the objecting Shareholder what BlackRock considers to be the fair value of their shares of common stock of ISIS. Within 50 days after the Reorganization, any Shareholder who has made a Payment Demand but has not received payment for his or her shares may petition a court of equity in Baltimore City, Maryland, for an appraisal to determine the "fair value" of such shares. If the court finds that a Shareholder is entitled to appraisal of his or her stock, the court will appoint three disinterested appraisers to determine the "fair value" of such shares on terms and conditions the court considers proper, and the appraisers will, within 60 days after appointment (or such longer period as the court may direct), file with the court and mail to each party to the proceeding their report stating their conclusion as to the "fair value" of the shares. Within 15 days after the filing of the report, any party may object to the report and request a hearing thereon. The court will, upon motion of any party, enter an order either confirming, modifying or rejecting the report and, if confirmed or modified, enter judgment directing the time within which payment must be made. If the appraisers' report is rejected, the court may determine the "fair value" of the shares of common stock of the Shareholder of ISIS requesting appraisal or may remit the proceeding to the same or other appraisers. Any judgment entered pursuant to a court proceeding will include interest from the date of the Meeting unless the court finds that the Shareholder's refusal to accept a written offer to 35 purchase the stock which may previously have been made by BlackRock in accordance with Section 3-207 of the Maryland General Corporation Law, was arbitrary and vexatious or not in good faith. BlackRock's costs of the proceeding (not including attorneys' fees) will be determined by the court and will be assessed against BlackRock or, under certain circumstances, the Shareholder, or both. At any time after the filing of a petition for appraisal, the court may require a Shareholder who has filed such petition to submit his or her certificates representing shares to the clerk of the court for notation of the pendency of the appraisal proceedings. In order to receive payment, whether by agreement with BlackRock or pursuant to a judgment, such Shareholder of ISIS must surrender the stock certificates endorsed in blank and in proper form for transfer. A Shareholder who has made a Payment Demand will not have the right to receive any dividends or distributions payable to holders of record after the close of business on the date of the Meeting and shall cease to have any rights as a Shareholder of ISIS with respect to the shares except the right to receive payment of the "fair value" thereof. The rights of a Shareholder who has made a Payment Demand may be restored only upon the withdrawal, with the consent of BlackRock, of the Payment Demand, failure to file a petition for appraisal within the time required, a determination of the court that the Shareholder is not entitled to an appraisal, or the abandonment or recession of the Reorganization. For information relating to the exercise of appraisal rights, see Appendix D to this Combined Prospectus/Proxy Statement. 36 Quorum. In the event that a quorum is not present at the Meeting, or in the event that a quorum is present at the Meeting but sufficient votes to approve the Reorganization Agreement are not received, the persons named as proxies, or their substitutes, may propose one or more adjournments of the Meeting to permit further solicitation of proxies. Any such adjournment will require the affirmative vote of a majority of those shares affected by the adjournment represented at the Meeting in person or by proxy. If a quorum is present, the persons named as proxies will vote those proxies which they are entitled to vote FOR the Reorganization Agreement in favor of such adjournment, and will vote those proxies required to be voted AGAINST such proposal, against any adjournment. A quorum is constituted with respect to ISIS by the presence in person or by proxy of the holders of a majority of the outstanding shares of ISIS entitled to vote at the Meeting. Proxies properly executed and marked with a negative vote, broker non-votes or an abstention will be considered to be present at the Meeting for the purposes of determining the existence of a quorum for the transaction of business. Annual Meetings. BlackRock does not presently intend to hold annual meetings of shareholders for the election of trustees and other business unless and until such time as required by law. Under certain circumstances, however, shareholders have the right to call a meeting of shareholders, and such meetings will be called when requested by the holders of record of 10% or more of BlackRock's outstanding shares of beneficial interest. To the extent required by law, BlackRock will assist in shareholder communications in such matters. In addition, BlackRock will hold special meetings of shareholders when required under the 1940 Act or in accordance with SEC policy. 37 ADDITIONAL INFORMATION ABOUT BLACKROCK Information about the High Yield Bond Portfolio and its Series B Investor Shares is included in the Prospectus dated January 28, 1999 accompanying this Combined Prospectus/Proxy Statement, which is incorporated by reference herein.

WHEREAS, the parties intend that all of the assets and liabilities of ISIS be transferred to, and be acquired and assumed by, the BlackRock High Yield Bond Portfolio (the "Acquiring Fund"), an investment portfolio offered by BlackRock, in exchange for Series B Investor Shares of the Acquiring Fund (the "Series B Investor Shares") which shall thereafter be distributed by ISIS to the holders of its shares, all as described in this Agreement (the "Reorganization"); WHEREAS, the parties intend that the transfer of assets, assumption of liabilities, and distribution of the Series B Investor Shares be treated as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"); and WHEREAS, the parties intend that after the Reorganization, the registration of ISIS as an investment company under the Investment Company Act of 1940, as amended (the "1940 Act") shall be terminated and ISIS shall be dissolved under state law as provided in this Agreement. NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth and subject to the terms and conditions hereof, and intending to be legally bound hereby, BlackRock and ISIS agree as follows: I. Transfer of Assets. ------------------ 1.01 At the Effective Time of the Reorganization (as defined in Article VIII), all property of every description, and all interests, rights, privileges and powers of ISIS except (i) cash in an amount necessary to pay any unpaid dividends and distributions as provided in Article IV(h) and (ii) corporate records of ISIS (such assets, the "Assets") shall be transferred and conveyed by ISIS to BlackRock on behalf of the Acquiring Fund, and shall be acquired by BlackRock on behalf of the Acquiring Fund, and BlackRock, on behalf of the Acquiring Fund, shall assume all liabilities, whether accrued, absolute, contingent or otherwise, of ISIS, which liabilities shall also include without limitation the obligation of ISIS to indemnify the directors and officers of ISIS to the fullest extent permitted by ISIS' Articles of Incorporation, as in effect at of the date of this Agreement (the "Liabilities"), so that at and after the Effective Time of the Reorganization: (i) the Assets shall become and be the assets of BlackRock on behalf of the Acquiring Fund; and (ii) the Liabilities shall be assumed by BlackRock on behalf of the Acquiring Fund. Without limiting the generality of the foregoing, the Assets shall include all property and assets of any nature whatsoever, including, without 2 limitation, all cash, cash equivalents, securities, claims and receivables (including dividend and interest receivables) owned by ISIS, and all deferred or prepaid expenses shown as assets on the books of ISIS, at the Effective Time of the Reorganization, and all good will, all other intangible property and all financial books and records belonging to ISIS. Recourse by any person for the Liabilities shall, at and after the Effective Time of the Reorganization, be limited to the Acquiring Fund. 1.02 In exchange for the transfer of the Assets and the assumption of the Liabilities, BlackRock shall simultaneously issue at the Effective Time of the Reorganization to ISIS that number of full and fractional (to the third decimal place) Series B Investor Shares of the Acquiring Fund that then have an aggregate net asset value equal to the aggregate net asset value at such time of the outstanding shares of common stock of ISIS. 1.03 The net asset value of the Series B Investor Shares of the Acquiring Fund shall be computed in the manner set forth in the Acquiring Fund's then current prospectus under the Securities Act of 1933, as amended (the "1933 Act"). The net asset value of the outstanding shares of common stock of ISIS shall be computed by the investment adviser of ISIS in accordance with the policies and procedures of ISIS that are then in effect, shall be reviewed by the independent auditors of ISIS and shall be subject to adjustment by the amount, if any, agreed to by BlackRock and 3 ISIS. ISIS shall deliver a copy of its valuation report to BlackRock at the Valuation Time (as defined in Article III). In the event that the value of a security in the portfolio of ISIS as determined in accordance with the policies and procedures of ISIS differs from the value of such security as determined in accordance with the valuation procedures of the Acquiring Fund, the Acquiring Fund's accounting agent shall make a final determination as to the value of such security, except that, if such valuation differs because of the amortization and/or accretion of premiums and discounts on such security, then such security shall be valued using ISIS' current methodology on premiums and discounts. 1.04 ISIS shall file Articles of Transfer for recordation with the Department of Assessments and Taxation of the State of Maryland, and shall take, in accordance with the Maryland General Corporation Law, all other steps as shall be necessary to effect the Reorganization. II. Liquidating Distribution and Termination of ISIS. Immediately after ------------------------------------------------ the Effective Time of the Reorganization, ISIS shall distribute in complete liquidation pro rata to its stockholders as of the Effective Time of the Reorganization the Series B Investor Shares of the Acquiring Fund received by ISIS in the Reorganization. In addition, the stockholders of ISIS shall have the right to receive any unpaid dividends or other distributions payable to them which were declared by ISIS before 4 the Effective Time of the Reorganization. In accordance with instructions it receives from ISIS, BlackRock shall record on its books the ownership of Series B Investor Shares of the Acquiring Fund by the record stockholders of ISIS. All of the outstanding shares of ISIS shall be cancelled on its books at the Effective Time of the Reorganization and shall thereafter represent only the right to receive the Series B Investor Shares of the Acquiring Fund, and the transfer books of ISIS shall be closed permanently. As soon as practicable after the Effective Time of the Reorganization, ISIS shall file an application pursuant to Section 8(f) of the 1940 Act for an order declaring that it has ceased to be an investment company and, upon receipt of such order, shall make all filings and take all other steps as shall be necessary and proper to effect its complete dissolution. After the Effective Time of the Reorganization, ISIS shall not conduct any business except in connection with its liquidation, deregistration, and dissolution. III. Valuation Time. The Valuation Time for the Reorganization shall be -------------- 4:00 p.m., Eastern time, on such date as may be agreed in writing by the duly authorized officers of BlackRock and ISIS. IV. Certain Representations, Warranties and Agreements of ISIS. ISIS ---------------------------------------------------------- represents and warrants to, and agrees with, BlackRock as follows: 5 (a) It is a Maryland corporation which was duly organized and is validly existing and in good standing under the laws of the State of Maryland.

(c) This Agreement has been duly authorized, executed and delivered by ISIS, and is valid and binding on ISIS, enforceable in accordance with its terms, subject to bankruptcy, insolvency, reorganization, arrangement, moratorium, and other similar laws of general applicability relating to or affecting creditor's rights and to general principles of equity.

(d) ISIS has elected to qualify and has qualified as a "regulated investment company" under Subtitle A, Chapter 1, Subchapter M, Part I of the Code, as of and since its first taxable year; has been a regulated investment company at all times since the end of its first taxable year when it so qualified; and qualifies and shall continue to qualify as a regulated investment company until the Effective Time of the Reorganization. (e) All federal, state, local and foreign income, profits, franchise, sales, withholding, customs, transfer and other taxes, including interest, additions to tax and penalties (collectively, "Taxes") relating to the Assets due or properly shown to be due on any return filed by ISIS with respect to taxable periods ending on or prior to, and the portion of any interim period up to, the date hereof have been fully and timely paid or provided for; and there are no levies, liens, or other encumbrances relating to Taxes existing, threatened or pending with respect to the Assets. 7 At the Effective Time of the Reorganization, all returns and reports of ISIS respecting Taxes required by law to have been filed by such time shall have been filed. (f) The financial statements of ISIS for its fiscal year ended December 31, 1998, audited by PricewaterhouseCoopers LLP, copies of which have been previously furnished to BlackRock, present fairly the financial position of ISIS as of December 31, 1998 and the results of its operations and the changes in its net assets for the period then ended, in conformity with generally accepted accounting principles.

(g) The unaudited financial statements of ISIS for the six-month period ended June 30, 1999, copies of which have been previously furnished to BlackRock, present fairly the financial position of ISIS as 8 of June 30, 1999 and the results of its operations for the period then ended, in conformity with generally accepted accounting principles. (h) Prior to the Valuation Time, ISIS shall have declared a dividend or dividends, with a record date and ex-dividend date prior to the Valuation Time, which, together with all previous dividends, shall have the effect of distributing to its stockholders all of its net investment company income, if any, for the taxable year ended on December 31, 1999 and for the period from said date to and including the Effective Time of the Reorganization (computed without regard to any deduction for dividends paid), and all of its net capital gain, if any, realized in the taxable year ended December 31, 1999 and for the period from said date to and including the Effective Time of the Reorganization.

RECENT PORTFOLIO MANAGEMENT ACTIVITY: . SINCE THE PORTFOLIO'S INCEPTION IN NOVEMBER 1998 THE HIGH YIELD MARKET HAS PERFORMED WELL AS YIELD SPREADS HAVE NARROWED COMPARED TO TREASURIES. INVESTORS CONTINUE TO EMPHAZISE HIGHER QUALITY NON-INVESTMENT GRADE CREDITS INSTEAD OF LOWER TIER CREDITS. THE MANAGER HAS TAKEN ADVANTAGE OF THIS DURING THE PERIOD BY FOCUSING ON B-RATED CREDITS, WHERE YIELD SPREADS CONTINUE TO TIGHTEN, WHILE UNDERWEIGHTING CCC-RATED SECURITIES. . THE PORTFOLIO HAS BENEFITED FROM BEING OVERWEIGHT RELATIVE TO THE INDEX IN THE TELECOM, OIL AND GAS AND CABLE SECTORS. PARTICULAR EMPHASIS HAS BEEN PLACED ON THESE SECTORS AS IMPROVING FUNDAMENTALS AND THE POTENTIAL FOR CONSOLIDATION CONTINUE TO BE A MAJOR CONTRIBUTOR TO THEIR STRONG PERFORMANCE. THE PORTFOLIO HAS BEEN UNDERWEIGHT THE HEALTHCARE AND TEXTILE SECTORS, WHICH HAVE BEEN WEAK PERFORMERS. . THE MANAGER BELIEVES THAT THE SUPPLY AND DEMAND TECHNICALS OF THE HIGH YIELD MARKET APPEAR TO BE FAVORABLE, AS STRONG MONEY INFLOWS AND LOWER SUPPLY RELATIVE TO LAST YEAR MAY BODE WELL FOR HIGH YIELD INVESTORS. Although the portfolio holdings and sectors listed above were current as of the end of the annual period ended September 30, 1999, the Portfolio is actively managed and the composition will vary.

Summary of Significant Accounting Policies Following is a summary of significant accounting policies which are consistently followed by BlackRock Funds High Yield Bond Portfolio/Independence Square Income Securities, Inc. in the preparation of its financial statements. The policies are in conformity with generally accepted accounting principles. Preparation of the financial statements includes the use of management estimates. Actual results could differ from those estimates. Security Valuation - Portfolio securities for which market quotations are readily available are valued at market value that is currently determined using the last reported sales price. If no sales are reported, for BlackRock Funds High Yield Portfolio, portfolio securities are valued at the mean between the last reported bid and asked prices. For Independence Square Income Securities, Inc. securities not listed or not traded on that day are valued at their most recent quoted bid prices or at prices determined by investment bankers or brokers. Short-term obligations with maturities of 60 days or less are valued at amortized cost, which approximates market value. For BlackRock Funds High yield Portfolio discounts and premiums on debt securities are amortized for book and tax purposes using the effective yield-to-maturity method over the term of the instrument. Independence Square Income Securities, Inc. does not amortize premiums or discounts on bonds held for investment for financial reporting or federal income tax purposes. Security Transactions and Investment Income - Investment transactions are accounted for on the trade date. The cost of investments sold is determined by use of the specific identification method for both financial reporting and federal income tax purposes. Interest income is recorded on the accrual basis. Federal Income Taxes - BlackRock Funds High Yield Portfolio/Independence Square Income Securities, Inc. intends to qualify for tax treatment applicable to regulated investment companies under the Internal Revenue Code of 1986 (the "Code"), as amended, and distribute all of its taxable income to its shareholders. Therefore, no provision has been recorded for Federal income or excise taxes. Distributions to Shareholders - Distributions from net investment income are declared by BlackRock Funds High Yield Bond Portfolio each day and monthly by Independence Square Income Securities, Inc. on "settled" shares. Both funds pay the net investment income monthly. Net realized capital gains, if any will be distributed annually. 12 FORM N-14 --------- Part C - Other Information -------------------------- Item 15. Indemnification. --------------- Indemnification of Registrant's principal underwriter against certain losses is provided for in Section 7 of the Distribution Agreement incorporated by reference herein as Exhibit 5(a). Indemnification of Registrant's Custodian, Transfer Agent and Administrators is provided for, respectively, in Section 22 of the Custodian Agreement incorporated by reference herein as Exhibit 7(a), Section 17 of the Transfer Agency Agreement incorporated by reference herein as Exhibit 8(c) and Section 11 of the Administration Agreement which is Exhibit 8(a) hereof. Registrant intends to obtain from a major insurance carrier a trustees and officers liability policy covering certain types of errors and omissions. In addition, Section 9.3 of the Registrant's Declaration of Trust incorporated by reference herein as Exhibit 1(a) provides as follows: Indemnification of Trustees, Officers, Representatives and Employees. -------------------------------------------------------------------- The Trust shall indemnify each of its Trustees against all liabilities and expenses (including amounts paid in satisfaction of judgments, in compromise, as fines and penalties, and as counsel fees) reasonably incurred by him in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, in which he may be involved or with which he may be threatened, while as a Trustee or thereafter, by reason of his being or having been such a Trustee except ------ with respect to any matter as to which he shall have been adjudicated to have acted in bad faith, willful misfeasance, gross negligence or reckless disregard of his duties, provided that as to any matter disposed of by a -------- compromise payment by such person, pursuant to a consent decree or otherwise, no indemnification either for said payment or for any other expenses shall be provided unless the Trust shall have received a written opinion from independent legal counsel approved by the Trustees to the effect that if either the matter of willful misfeasance, gross negligence or reckless disregard of duty, or the matter of bad faith had been adjudicated, it would in the opinion of such counsel have been adjudicated in favor of such person. The rights accruing to any person under these provisions shall not exclude any other right to which he may be lawfully entitled, provided that no person may satisfy any right of indemnity or -------- reimbursement hereunder except out of the property of the Trust. The Trustees may make advance payments in connection with the indemnification under this Section 9.3, provided that the indemnified person shall have -------- given a written undertaking to reimburse the Trust in the event it is subsequently determined that he is not entitled to such indemnification. The Trustee shall indemnify officers, representatives and employees of the Trust to the same extent that Trustees are entitled to indemnification pursuant to this Section 9.3. C-1 Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to trustees, officers and controlling persons of Registrant pursuant to the foregoing provisions, or otherwise, Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Registrant of expenses incurred or paid by a trustee, officer or controlling person of Registrant in the successful defense of any action suit or proceeding) is asserted by such trustee, officer or controlling person in connection with the securities being registered, registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. Section 9.6 of the Registrant's Declaration of Trust, filed herein as Exhibit 1(a), also provides for the indemnification of shareholders of the Registrant. Section 9.6 states as follows: Indemnification of Shareholders. In case any Shareholder or former ------------------------------- Shareholder shall be held to be personally liable solely by reason of his being or having been a Shareholder and not because of his acts or omissions or for some other reason, the Shareholder or former Shareholder (or his heirs, executors, administrators or other legal representatives or, in the case of a corporation or other entity, its corporate or other general successor) shall be entitled out of the assets belonging to the classes of Shares with the same alphabetical designation as that of the Shares owned by such shareholder to be held harmless from and indemnified against all loss and expense arising from such liability. The Trust shall, upon request by the Shareholder, assume the defense of any claim made against any Shareholder for any act or obligations of the Trust and satisfy any judgment thereon from such assets.
