NOT FDIC MAY LOSE VALUE INSURED NO BANK GUARANTEE TO OUR FELLOW SHAREHOLDERS HIGHLAND INSTITUTIONAL FLOATING RATE INCOME FUND DEAR SHAREHOLDER: I am pleased to submit this annual report for the period ended August 31, 2004. I am also pleased to have announced on April 15, 2004 that Highland Capital Management, L.P. ("Highland") entered into a new investment advisory agreement with the Highland Institutional Floating Rate Income Fund, formerly Columbia Institutional Floating Rate Income Fund. The agreement was approved at a special meeting of the Fund's shareholders held on July 30, 2004. As you may know, since April 15, 2004, when the investment management of the Fund was transferred to Highland and the distribution of the Fund to PFPC Distributors, Inc., Highland acted as advisor to the Fund under an interim agreement pending final shareholder approval. At the shareholder meeting, five new Trustees were elected to the Fund's Board of Trustees. The Fund's Board of Trustees now consists of: Timothy K. Hui, Scott F. Kavanaugh, James F. Leary, Bryan A. Ward and R. Joseph Dougherty. Mr. Dougherty is the only Trustee affiliated with Highland. Biographical information for each Trustee can be found in the report that follows. Effective October 18, 2004, PFPC Inc. ("PFPC") replaced Columbia Funds Services, Inc. as the Fund's transfer agent. As of that date, PFPC assumed all account servicing responsibilities for the Fund. Some changes that will affect shareholders of the Highland Institutional Floating Rate Income Fund include the following: Effective October 18, 2004, the name of the Fund changed from Columbia Institutional Floating Rate Income Fund to Highland Institutional Floating Rate Income Fund and you should anticipate new fund CUSIP numbers. (A CUSIP is a unique identification number assigned to each class of a fund by the Committee on Uniform Security Identification Procedures.) Ticker symbols for the Fund will remain the same. A list of the new CUSIP numbers and other information related to these changes are available online at www.highlandfunds.com, our new website. Please don't hesitate to contact your financial advisor or call Shareholder Services at 877-665-1287 for more information. In the report that follows, your portfolio manager talks in depth about investment strategies and other factors that affected your Fund's performance during the period. I encourage you to read the report carefully. I thank you for your business and I look forward to continuing to serve your investment needs. Sincerely, /s/ James D. Dondero James D.

There are transaction costs, which generally include sales charges on purchases and may include redemption or exchange fees. There are also continuing costs, which generally include investment advisory and/or Rule 12b-1 fees, and other fund expenses. The information on this page is intended to help you understand your ongoing costs of investing in the fund and to compare this cost with the continuing costs of investing in other funds. ANALYZING YOUR FUND'S EXPENSES To illustrate these ongoing costs, we have provided an example and calculated the expenses paid by investors in each share class during the reporting period. The information in the following table is based on an initial investment of $1,000, which is invested at the beginning of the reporting period and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the "actual" column is calculated using the fund's actual operating expenses and total return for the period. The amount listed in the "hypothetical" column for each share class assumes that the return each year is 5% before expenses and includes the fund's actual expense ratio. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during this reporting period. MARCH 1, 2004 - AUGUST 31, 2004 <Table> <Caption> ACCOUNT VALUE AT THE ACCOUNT VALUE AT THE EXPENSES PAID FUND'S ANNUALIZED BEGINNING OF THE PERIOD ($) END OF THE PERIOD ($) DURING THE PERIOD ($) EXPENSE RATIO (%) ACTUAL HYPOTHETICAL ACTUAL HYPOTHETICAL ACTUAL HYPOTHETICAL 1,000.00 1,000.00 1,009.17 1,008.87 3.79 3.79 0.75 </Table> Expenses paid during the period are equal to the fund's annualized expense ratio, multiplied by the average account value over the period, then multiplied by the number of days in most recent fiscal half-year and divided by 366. Had the advisor or its affiliates not waived or reimbursed a portion of expenses, total return would have been reduced. It is important to note that the expense amounts shown in the table are meant to highlight only continuing costs of investing in the fund and do not reflect any transactional costs, such as sales charges, redemption or exchange fees. Therefore, the hypothetical examples provided will not help you determine the relative total costs of owning different funds. If these transactional costs were included, your costs would have been higher. COMPARE WITH OTHER FUNDS Since all funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the fund with other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other fund companies, it is important to note that hypothetical examples are meant to highlight the continuing cost of investing in a fund and do not reflect any transactional costs, such as sales charges or redemption or exchange fees. [SIDENOTE] ESTIMATING YOUR ACTUAL EXPENSES To estimate the expenses that you paid over the period, first you will need your account balance at the end of the period: - - For shareholders who receive their account statements from PFPC Inc., your account balance is available online at www.highlandfunds.com or by calling Shareholder Services at 877.665.1287 - - For shareholders who receive their account statements from their brokerage firm, contact your brokerage firm to obtain your account balance. 1. Divide your ending account balance by $1,000. For example, if an account balance was $8,600 at the end of the period, the result would be 8.6 2. In the section of the table below titled "Expenses paid during the period," locate the amount for your share class. You will find this number is in the column labeled "actual." Multiply this number by the result from step 1. Your answer is an estimate of the expenses you paid on your account during the period 3 <Page> ECONOMIC UPDATE HIGHLAND INSTITUTIONAL FLOATING RATE INCOME FUND Despite occasional uncertainty about jobs and consumer spending, the US economy grew at a pace of more than 4.5% during the 12-month period that began September 1, 2003 and ended August 31, 2004. Growth slowed in the final months of the period, and many economists lowered their expectations for the balance of 2004. Nevertheless, the US economy remained on solid ground. Consumer confidence seesawed, mostly in reaction to changing job data, which dominated much of the economic news during the year. The Conference Board reported that confidence declined on weak job figures early in 2004. Confidence rose after the US labor markets added more than 1.2 million new jobs between March and May. However, disappointing job creation in June and July curbed consumer enthusiasm again in August. Consumers expressed their confidence in the economy by spending on retail goods, autos and housing. Low mortgage rates continued to fuel a red-hot housing market. However, consumer spending declined in two of the last three months of the period, the first such pullback in a year. Businesses stepped into the gap and helped fuel the economy during the period. Industrial production rose and factories utilized more of their capacity. Spending on technology and capital equipment picked up, and outlays for office and warehouse construction turned the corner after a three-year downturn. BONDS DELIVER RESPECTABLE RETURNS Despite periods of interest rate volatility, the US bond market delivered respectable gains. The yield on the 10-year US Treasury bond drifted generally lower for the first eight months of the period. Then it rose sharply as the economy strengthened, the employment picture brightened and investors began to anticipate a shift in the Federal Reserve Board's policy on short-term interest rates. The Fed delivered on these expectations and raised the federal funds rate, a key short-term rate, twice during the period--from 1.0% to 1.25% in June and to 1.50% in August.(1) A shaky stock market, higher energy prices and some weak economic data gave the bond market a boost in July and August as the 10-year Treasury yield fell to 4.1%, ending the period lower than where it started. As a result, the Lehman Brothers Aggregate Bond Index, a broad measure of investment grade bond market performance, returned 6.13%. Municipals were the best performers among investment-grade bonds, returning 7.11% as measured by the Lehman Municipal Bond Index. However, the high-yield sector outdistanced all other sectors. The Merrill Lynch US High Yield, Cash Pay Index returned 13.64%. US STOCKS OUTPERFORMED BONDS Buoyed by strong gains at the beginning of the period, the S&P 500 Index returned 11.46% during this 12-month reporting period. However, concerns about new terror threats and higher interest rates and energy prices sidelined investors as the period wore on. Late in the period, leadership passed from small-cap stocks, which were strong performers early in the period, to mid- and large-cap stocks. Value stocks continued to lead growth stocks. Energy stocks and real estate investment trusts were the best-performing sectors for the period. (1) The federal funds rate was raised to 1.75% in September. [SIDENOTE] SUMMARY FOR THE ONE-YEAR PERIOD ENDED AUGUST 31, 2004 - - Performance in the fixed income universe was led by high yield bonds. As measured by the Merrill Lynch US High Yield, Cash Pay Index, this sector posted a return more than seven percentage points higher than the return for investment-grade bonds, as measured by the Lehman Brothers Aggregate Bond Index. - - The US stock market rose as the economy strengthened. Both the Russell 3000 Index, which tracks approximately 98% of the US stock market, and the S&P 500 Index posted double-digit returns this period.

That was greater than the return of the fund's benchmark, the CSFB Leveraged Loan Index, which was 7.05% for the period. The fund also outperformed the Lipper Loan Participation Funds Category average, which was 8.82%.(1) These high returns reflect an advantageous environment for all types of credit instruments. We believe the fund was able to outperform because of favorable security selection and sector allocation. A STRONG CREDIT ENVIRONMENT The period ended August 31, 2004 was another strong year for the credit markets, fueled by improved earnings, strong job growth and increased demand for floating-rate loans. However, financial markets faced pressure from the political instability in the Middle East, high oil prices and increased interest rates. During both its June 30 and August 10 meetings, the Federal Reserve increased the fed funds rate 25 basis points, bringing the fed funds rate to 1.50%. Leveraged loan default rates continued to drop as corporate balance sheets improved. CABLE AND TELECOM - RESPECTABLE GAINS Cable and satellite television, which constituted 9.3% of the Portfolio's net assets, performed well for the portfolio. Century Cable and Olympus Cable (1.5% and 1.1% of net assets, respectively) had another strong year for the portfolio. Both of these holdings are wholly-owned subsidiaries of Adelphia, a cable industry bellwether. The portfolio's position in telecommunications contributed significantly to the Fund's strong performance. Telecommunications, which accounted for 8.6% of the portfolio's net assets, showed continued strength for the second year. Cricket Communications was a very solid performer for the portfolio. After trading well above par, the bank loans converted to Cricket Communications notes and equity in Leap Wireless during the year. Both the notes and equity had strong performance through the end of the period. Cricket Communications and Leap Wireless were 0.1% and 0.2% of net assets, respectively. (1) Lipper, Inc., a widely respected data provider in the industry, calculates an average total return for mutual funds with similar investment objectives as the fund. This fund falls under the Lipper Loan Participation Category average.

Information provided is calculated as a percentage of net assets. 5 <Page> The fund did not experience any major defaults during the period. Many lower rated companies have improved their financial condition via newfound access to the high yield bond market. As a result, lower quality credits performed well again this year. /s/ Mark Okada /s/ Joe Dougherty Mark Okada and Joe Dougherty have been portfolio managers of the Highland Institutional Floating Rate Income Fund since April 15, 2004. Just like any other investment, floating rate loan investments present financial risks. Defaults on the loans in the portfolio could reduce the fund's net asset value and its distributions, as could nonpayment of scheduled interest and principal. Prepayment of principal by a borrower could mean that the portfolio managers have to replace the loan with a lower-yielding security, which could affect the valuation of the portfolio's holdings. The fund is a continuously offered, closed-end management investment company and provides limited liquidity through a quarterly tender offer for between 5% and 25% of outstanding shares. Each quarter, the fund's trustees must approve the actual tender amount. Please read the prospectus carefully for more details. The Portfolio may invest a high percentage of assets in a limited number of loans, so the default of any individual holding can have a greater impact on the fund's net asset value than could a default in a more diversified portfolio. Floating rate loans are not covered by FDIC insurance or other guarantees relating to timely payment of principal and interest. Since economic and market conditions change frequently, there can be no assurance that the trends described here will continue or that the forecasts will come to pass. The opinions expressed are those of the portfolio managers and are subject to change. Prior investment returns are not indicative of future results. 6 <Page> FINANCIAL STATEMENTS AUGUST 31, 2004 HIGHLAND INSTITUTIONAL FLOATING RATE INCOME FUND A GUIDE TO UNDERSTANDING YOUR FUND'S FINANCIAL STATEMENTS INVESTMENT PORTFOLIO The investment portfolio details all of the fund's holdings and their market value as of the last day of the reporting period. Portfolio holdings are organized by type of asset, industry, country or geographic region (if applicable) to demonstrate areas of concentration and diversification. STATEMENT OF ASSETS AND LIABILITIES This statement details the fund's assets, liabilities, net assets and share price for each share class as of the last day of the reporting period. Net assets are calculated by subtracting all the fund's liabilities (including any unpaid expenses) from the total of the fund's investment and non-investment assets. The share price for each class is calculated by dividing net assets for that class by the number of shares outstanding in that class as of the last day of the reporting period. STATEMENT OF OPERATIONS This statement details income earned by the fund and the expenses accrued by the fund during the reporting period. The Statement of Operations also shows any net gain or loss the fund realized on the sales of its holdings during the period, as well as any unrealized gains or losses recognized over the period. The total of these results represents the fund's net increase or decrease in net assets from operations. STATEMENT OF CHANGES IN NET ASSETS This statement demonstrates how the fund's net assets were affected by its operating results, distributions to shareholders and shareholder transactions (e.g., subscriptions, redemptions and dividend reinvestments) during the reporting period. The Statement of Changes in Net Assets also details changes in the number of shares outstanding. STATEMENT OF CASH FLOWS The statement of cash flows reports net cash provided or used by operating, investing and financing activities and the net effect of those flows on cash and cash equivalents during the period.

ORGANIZATION Highland Institutional Floating Rate Income Fund (the "Fund") formerly Columbia Institutional Floating Rate Income Fund, is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended, as a non-diversified, closed-end management investment company. Effective October 13, 2003, the Fund changed its name from Stein Roe Institutional Floating Rate Income Fund to Columbia Institutional Floating Rate Income Fund. Also on that date, the Portfolio changed its name from Stein Roe Floating Rate Limited Liability Company to Columbia Floating Rate Limited Liability Company. Effective October 18, 2004, the Columbia Institutional Floating Rate Income Fund was renamed Highland Institutional Floating Rate Income Fund. Also on that date, the Columbia Floating Rate Limited Liability Company was renamed Highland Floating Rate Limited Liability Company. INVESTMENT GOAL The Fund invests all of its investable assets in Highland Floating Rate Limited Liability Company (the "Portfolio") formerly Columbia Floating Rate Limited Liability Company. The Portfolio seeks a high level of current income consistent with preservation of capital. THE PORTFOLIO The Portfolio is a non-diversified, closed-end management investment company organized as a Delaware limited liability company. The Portfolio allocates income, expenses, realized and unrealized gains and losses to each investor on a daily basis, based on methods in compliance with the Internal Revenue Code. At August 31, 2004, the Fund and the Columbia Floating Rate Fund owned 7.4% and 92.6%, respectively, of the Portfolio. FUND SHARES The Fund may issue an unlimited number of shares, which are offered continuously at net asset value. NOTE 2. SIGNIFICANT ACCOUNTING POLICIES USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies consistently followed by the Portfolio and the Fund in the preparation of their financial statements. SECURITY VALUATION The value of the Portfolio is determined in accordance with guidelines established and periodically reviewed by the Board of Trustees. Senior loans are generally valued using market prices or quotations provided by banks, dealers or pricing services with respect to secondary market transactions. The prices provided by these principal market makers may differ from the value that would be realized if the loans were sold and the difference could be material to the financial statements. In the absence of actual market values, the senior loans will be valued at fair value, which is intended to approximate market value, pursuant to procedures approved by the Board of Trustees. In determining fair value, the following factors, among others, will be considered on an on-going basis: (i) the creditworthiness of the Borrower; (ii) the current interest rate, the interest rate redetermination period and maturity of such senior loan interests; and (iii) recent prices in the market for instruments of similar quality, rate and interest rate redeterminiation period and maturity. Because of uncertainty inherent in the valuation process, the estimated value of a senior loan may differ significantly from the value that would have been used had there been market activity for that senior loan interest. Equity securities are valued at the last sale price on the principal exchange on which they trade, except for securities traded on the NASDAQ, which are valued at the NASDAQ official close price. Unlisted securities or listed securities for which there were no sales during 33 <Page> the day are valued at the closing bid price on such exchanges or over-the-counter markets. Short-term debt obligations maturing within 60 days are valued at amortized cost, which approximates market value. Investments for which market quotations are not readily available, or quotations which management believes are not appropriate, are valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees. SECURITY TRANSACTIONS Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes. REPURCHASE AGREEMENTS The Portfolio may engage in repurchase agreement transactions with institutions that the Portfolio's investment advisor has determined are creditworthy. The Portfolio, through its custodian, receives delivery of underlying securities collateralizing a repurchase agreement. Collateral is at least equal, at all times, to the value of the repurchase obligation including interest. A repurchase agreement transaction involves certain risks in the event of default or insolvency of the counterparty. These risks include possible delays or restrictions upon the Portfolio's ability to dispose of the underlying securities and a possible decline in the value of the underlying securities during the period while the Portfolio seeks to assert its rights. INCOME RECOGNITION Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. Facility fees received are treated as market discounts. Unamortized facility fees are reflected as deferred fees on the Statement of Assets and Liabilities. FEDERAL INCOME TAX STATUS The Fund intends to qualify each year as a "regulated investment company" under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its taxable income, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Portfolio is treated as a partnership for federal income tax purposes and all of its income is allocated to its owners based on methods in compliance with the Internal Revenue Service. Therefore, no federal income tax provision is recorded. DISTRIBUTIONS TO SHAREHOLDERS Dividends from net investment income are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. STATEMENT OF CASH FLOWS Information on financial transactions which have been settled through the receipt or disbursement of cash is presented in the Statement of Cash Flows. The cash amount shown in the Statement of Cash Flows is the amount included within the Portfolio's Statement of Assets and Liabilities and includes cash on hand at its custodian bank and does not include any short-term investments. NOTE 3. FEDERAL TAX INFORMATION The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to the Fund's capital accounts for permanent tax differences to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations. For the year ended August 31, 2004, permanent differences resulting primarily from differing treatments for discount accretion/premium amortization on debt securities were identified and reclassified among the components of the Fund's net assets as follows: <Table> <Caption> OVERDISTRIBUTED ACCUMULATED NET INVESTMENT NET REALIZED PAID-IN INCOME LOSS CAPITAL - ------------------------------------------------------------ $ 14,128 $ (14,129) $ 1 </Table> Net investment income and net realized gains (losses), as disclosed on the Statement of Operations, and net assets were not affected by this reclassification. 34 <Page> The tax character of distributions paid during the years ended August 31, 2004 and August 31, 2003 was as follows: <Table> <Caption> AUGUST 31, AUGUST 31, 2004 2003 - -------------------------------------------------------------------------------- DISTRIBUTIONS PAID FROM: ORDINARY INCOME* $ 3,568,779 $ 5,397,399 </Table> *For tax purposes short-term capital gains distributions, if any, are considered ordinary income distributions. As of August 31, 2004, the components of distributable earnings on a tax basis were as follows: <Table> <Caption> UNDISTRIBUTED UNDISTRIBUTED ORDINARY LONG-TERM NET UNREALIZED INCOME CAPITAL GAINS APPRECIATION* - ----------------------------------------------------------------------- $ 35,698 $ -- $ 42,839 </Table> *The differences between book-basis and tax-basis net unrealized appreciation/depreciation are primarily due to deferral of losses from wash sales and accretion/amortization on debt securities. Portfolio unrealized appreciation and depreciation at August 31, 2004, based on cost of investments for federal income tax purposes and excluding any unrealized appreciation and depreciation from changes in the value of other assets and liabilities resulting from changes in exchange rates, was: <Table> UNREALIZED APPRECIATION $ 59,826,952 UNREALIZED DEPRECIATION (59,232,503) --------------- NET UNREALIZED APPRECIATION $ 594,449 </Table> The following capital loss carryforwards may be available to reduce taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code: <Table> <Caption> YEAR OF CAPITAL LOSS EXPIRATION CARRYFORWARD - ---------------------------------------------------------------- 2009 $ 16,991 2010 2,799,382 2011 1,685,798 2012 2,947,361 $ 7,449,532 </Table> NOTE 4. FEES AND COMPENSATION PAID TO AFFILIATES Effective April 15, 2004, Highland Capital Management, L.P. ("Highland") is the investment advisor to the Portfolio and the Fund. Prior to April 15, 2004, Columbia Management Advisors, Inc. ("Columbia") was the investment advisor to the Portfolio and the Fund. Columbia was an indirect, wholly owned subsidiary of FleetBoston Financial Corporation ("FleetBoston"), however effective April 1, 2004, FleetBoston, including the Portfolio's and the Fund's investment advisor, transfer agent and distributor, was acquired by Bank of America Corporation ("BOA"). The change in investment advisor will not impact the Portfolio's investment strategy. INVESTMENT ADVISORY FEE Highland receives a monthly investment advisory fee based on the Portfolio's average daily net assets at the following annual rates: <Table> <Caption> AVERAGE DAILY NET ASSETS ANNUAL FEE RATE - ----------------------------------------------------------- FIRST $1 BILLION 0.45% NEXT $1 BILLION 0.40% OVER $2 BILLION 0.35% </Table> For the period November 1, 2003 through April 14, 2004, Columbia received a monthly investment advisory fee based on the same fee schedule. Prior to November 1, 2003, Columbia was entitled to receive a monthly investment advisory fee at the annual rate of 0.45% of the Portfolio's average daily net assets. For the year ended August 31, 2004, the Portfolio's effective investment advisory fee rate was 0.45%. ADMINISTRATION FEES During the year ended August 31, 2004, Columbia provided administrative and other services to the Fund for a monthly administration fee at the annual rate of 0.20% of the Fund's average daily net assets. Effective October 18, 2004, Highland replaced Columbia to provide administrative services to the Fund for a monthly administration fee at the annual rate of 0.20% of the Fund's average daily managed assets. Also effective October 18, 2004, under a separate agreement, Highland has delegated certain administrative functions to PFPC, Inc. ("PFPC"). PFPC receives a fee from Highland at the annual rate of 0.01% of the Fund's average daily managed assets. PRICING AND BOOKKEEPING FEES During the year ended August 31, 2004, Columbia was responsible for providing pricing and bookkeeping services to the Portfolio and the Fund under a pricing and bookkeeping agreement. Under a separate agreement (the "Outsourcing Agreement"), Columbia delegated those functions to State Street Corporation ("State Street"). As a result, Columbia paid the total fees collected to State Street under the Outsourcing 35 <Page> Agreement. Under its pricing and bookkeeping agreement with the Portfolio and the Fund, Columbia received from the Portfolio and the Fund an annual flat fee of $10,000 and $5,000, respectively, paid monthly, and in any month that the Fund's average daily net assets exceeded $50 million, an additional monthly fee. The additional fee rate was calculated by taking into account the fees payable to State Street under the Outsourcing Agreement. This rate is applied to the average daily net assets of the Fund for that month. The Portfolio also paid additional fees for pricing services based on the number of securities held by the Portfolio. For the year ended August 31, 2004, the Fund's and the Portfolio's effective pricing and bookkeeping fee rates, inclusive of out-of-pocket expenses, was 0.031% and 0.030% respectively. Effective October 18, 2004, the pricing and bookkeeping agreement with Columbia was terminated, and the Fund entered into a new agreement with PFPC to provide accounting services. TRANSFER AGENT FEE During the year ended August 31, 2004, Columbia Funds Services, Inc. (the "Transfer Agent"), an affiliate of Columbia, provided shareholder services to the Fund. For such services, the Transfer Agent received a fee, paid monthly, at the annual rate of $34.00 per open account. The Transfer Agent also received reimbursement for certain out-of-pocket expenses. The Portfolio paid the Transfer Agent a monthly fee equal to $6,000 annually. Prior to November 1, 2003, the Transfer Agent was entitled to receive a monthly transfer agent fee, in addition to reimbursement for certain out-of-pocket expenses, at the annual rate of 0.06% of the Fund's average daily net assets plus flat-rate charges based on the number of shareholder accounts and transactions. For the year ended August 31, 2004, the Fund's and the Portfolio's effective transfer agent fee rate, inclusive of out-of-pocket expenses, was 0.02% and 0.001% respectively. Effective October 18, 2004, PFPC replaced Columbia Funds Services, Inc., to provide shareholder services to the Fund. EXPENSE LIMITS AND FEE REIMBURSEMENTS Highland has voluntarily agreed to waive fees and reimburse certain expenses to the extent that total expenses (inclusive of allocated Portfolio expenses but exclusive of brokerage commissions, interest, commitment fees, taxes and extraordinary expenses, if any) exceed 0.75% annually of the Fund's average daily net assets. This arrangement may be revised or discontinued by Highland at any time. Prior to April 15, 2004, Columbia voluntarily waived fees and reimbursed certain expenses of the Fund based on the same fee structure. CUSTODY CREDITS During the year ended August 31, 2004, the Portfolio had an agreement with its custodian bank under which custody fees may be reduced by balance credits. The Portfolio could have invested a portion of the assets utilized in connection with the expense offset arrangement in an income-producing asset if it had not entered into such an agreement. Effective October 18, 2004, the agreement with its former custodian bank was terminated. FEES PAID TO OFFICERS AND TRUSTEES Effective August 5, 2004, new officers of the Fund were elected. The Fund pays no compensation to these officers, all of whom are employees of Highland. Prior to this date, all of the Fund's officers were employees of Columbia or its affiliates. The Fund's previous officers also received no compensation from the Fund. Effective July 30, 2004, the shareholders of the Fund voted to elect a new Board of Trustees in connection with the change in Investment Advisor. The Portfolio pays each Trustee of the Fund a flat rate fee of $20,000 per year for services provided as a Board member of the Fund. This fee is allocated between the Fund and the Highland Floating Rate Fund. Prior to July 30, 2004, the previous Trustees of the Fund participated in a deferred compensation plan. Any continuing obligations of the plan will be paid solely out of the Fund's assets. OTHER Columbia provided certain services to the Fund related to Sarbanes-Oxley compliance. For the year ended August 31, 2004, the Fund paid $1,428 to Columbia for such services. This amount is included in "Other expenses" on the Statement of Operations. NOTE 5. PORTFOLIO INFORMATION For the year ended August 31, 2004, the cost of purchases and proceeds from sales of securities, 36 <Page> excluding short-term obligations, were $891,194,827 and $612,433,161, respectively. NOTE 6. TENDER OF SHARES The Board of Trustees has adopted a policy of making tender offers on a quarterly basis. The Board has designated the 15th day of March, June, September and December of each year, or the next business day if the 15th is not a business day, as the Repurchase Request Deadline. Tender offers are made for a portion of the Fund's outstanding shares at the net asset value of the shares as of the Repurchase Pricing Date. The tender amount, which is determined by the Board of Trustees, will be at least 5% and no more than 25% of the total number of shares outstanding on the Repurchase Request Deadline. The Fund may repurchase an additional amount of shares up to 2% of the shares outstanding on the Repurchase Request Deadline if the shareholders' offer for repurchase exceeds the Repurchase Offer Amount. For the year ended August 31, 2004, there were four tender offers in September, December, March and June. For each tender, the Fund offered to repurchase 10%, 10%, 10% and 25%, respectively, of its shares, and 8.50%, 0.00%, 1.28% and 26.81%, respectively, of shares outstanding were tendered. NOTE 7. SENIOR LOAN PARTICIPATION COMMITMENTS The Portfolio invests primarily in participations and assignments, or acts as a party to the primary lending syndicate of Variable Rate Senior Loan interests to United States corporations, partnerships, and other entities. If the lead lender in a typical lending syndicate becomes insolvent, enters FDIC receivership or, if not FDIC insured enters into bankruptcy, the Portfolio may incur certain costs and delays in receiving payment or may suffer a loss of principal and/or interest. When the Portfolio purchases a participation of a senior loan interest, the Portfolio typically enters into a contractual agreement with the lender or other third party selling the participation, not with the borrower directly. As such, the Portfolio assumes the credit risk of the Borrower, Selling Participant or other persons interpositioned between the Portfolio and the Borrower. The ability of Borrowers to meet their obligations may be affected by economic developments in a specific industry. At August 31, 2004, the following sets forth the selling participants with respect to interests in senior loans purchased by the Portfolio on a participation basis. <Table> <Caption> PRINCIPAL SELLING PARTICIPANT AMOUNT VALUE - -------------------------------------------------------------------------------- CITIBANK: INSIGHT HEALTH SERVICES CORP. TERM LOAN B $ 4,353,030 $ 4,385,678 NEXTEL FINANCE CO, INC. TERM LOAN E 2,992,481 3,011,645 GOLDMAN SACHS: BRIDGE INFORMATION SYSTEMS, INC. MULTIDRAW TERM LOAN 508,890 30,533 </Table> NOTE 8. UNFUNDED LOAN COMMITMENTS As of August 31, 2004, the Portfolio had unfunded loan commitments of $16,117,889, which could be extended at the option of the Borrower, pursuant to the following loan agreements: <Table> <Caption> UNFUNDED BORROWER COMMITMENT - -------------------------------------------------------------------------------- CELANESE $ 1,861,107 CENTENNIAL CELLULAR OPERATING CO - TRANCHE B REVOLVER 2,250,000 CSC HOLDINGS, INC. 395,833 DOBSON CELLULAR SYSTEMS, INC. - REVOLVER 1,016,667 FEDERAL-MOGUL CORP. 109,615 SBA SENIOR FINANCE 484,615 TYCO INTERNATIONAL GROUP SA 10,000,000 ------------- $ 16,117,889 </Table> NOTE 9. LINE OF CREDIT During the year ended August 31, 2004, the Portfolio and other affiliated funds participate in a $350,000,000 credit facility, or emergency purposes to facilitate portfolio liquidity. Interest was charged to the Portfolio based on its borrowings. In addition, the Portfolio agreed to pay commitment fees on its pro-rata portion of the unutilized line of credit. The commitment fee is included in "Other expenses" on the Statement of Operations. For the year ended August 31, 2004, the average daily loan balance outstanding on days where borrowings existed was $36,714,286 at a weighted average interest rate of 1.55%. Effective September 13, 2004, the $350,000,000 credit facility was terminated and the Portfolio entered into a $150,000,000 credit facility which replaced the credit facility mentioned above. The new credit facility is used for temporary or emergency purposes to facilitate portfolio liquidity. Interest is charged to the Portfolio based on its 37 <Page> borrowings. In addition, the Portfolio has agreed to pay commitment fees on the unutilized line of credit. NOTE 10. SHARES OF BENEFICIAL INTEREST As of August 31, 2004, 91.7% of the outstanding shares of the Fund were held by five shareholders, each of which represents in excess of 5% of the Fund's shares outstanding. Subscription and redemption activity of these shareholders may have a material effect on the Fund. NOTE 11. DISCLOSURE OF SIGNIFICANT RISKS AND CONTINGENCIES INDUSTRY FOCUS The Fund may focus its investments in certain industries, subjecting it to greater risk than a fund that is more diversified. NON-PAYMENT RISK Senior Loans, like other corporate debt obligations, are subject to the risk of non-payment of scheduled interest or principal. Non-payment would result in a reduction of income to the Portfolio, a reduction in the value of the Senior Loan experiencing non-payment and a potential decrease in the net asset value of the Fund. CREDIT RISK Securities rated below investment grade are commonly referred to as high-yield, high risk or "junk debt". They are regarded as predominantly speculative with respect to the issuing company's continuing ability to meet principal and interest payments. Investments in high-yield Senior Loans may result in greater net asset value fluctuation than if the Portfolio did not make such investments. LEGAL PROCEEDINGS Columbia, Columbia Funds Distributor, Inc. ("CFDI"), certain of their affiliates and the Fund (collectively, "The Columbia Group"), have received information requests and subpoenas from various regulatory and law enforcement authorities in connection with their investigations of late trading and market timing in mutual funds as well as other industry wide issues. On February 24, 2004, the Securities and Exchange Commission ("SEC") filed a civil complaint in the United States District Court for the District of Massachusetts against Columbia and CFDI, alleging that they had violated certain provisions of the federal securities laws in connection with trading activity in mutual fund shares. Also on February 24, 2004, the New York Attorney General ("NYAG") filed a civil complaint in New York Supreme Court, County of New York against Columbia and CFDI alleging that Columbia and CFDI had violated certain New York anti-fraud statutes. On March 15, 2004, Columbia and CFDI entered into agreements in principle with the SEC Division of Enforcement and NYAG in settlement of the charges. In a separate agreement with the NYAG, the Columbia Group and its affiliate Banc of America Capital Management, LLC have agreed to collectively reduce mutual fund fees by $160 million over a five-year period. As a result of these matters or any adverse publicity or other developments resulting from them, there may be increased redemptions or reduced sales of fund shares, which could increase transaction costs or operating expenses, or have other adverse consequences for the fund. In connection with the events described in detail above, various parties have filed suit against certain funds (including the Fund), their Boards and/or FleetBoston (and affiliated entities). More than 300 cases (including those filed against entities unaffiliated with the funds, their Boards and/or FleetBoston and its affiliated entities) have been consolidated in a multi-district proceeding and transferred to the Federal District Court in Maryland. Recently, certain Columbia funds and affiliated entities and the Fund have been named as defendants in several derivative actions under various sections of the Investment Company Act of 1940, as amended, alleging, among other things, that the fees and expenses paid by those funds are excessive. The funds and the other defendants to these actions, including Columbia and various affiliates, certain other mutual funds advised by Columbia and its affiliates, and various directors of such funds and the Fund have denied these allegations and are contesting the plaintiffs' claims. These suits and certain regulatory investigations are ongoing, however, based on currently available information, Columbia believes that these lawsuits are without merit and that the likelihood they will have a material adverse impact on any fund is remote. 38 <Page> This page intentionally left blank. <Page> FINANCIAL HIGHLIGHTS HIGHLAND FLOATING RATE LIMITED LIABILITY COMPANY SELECTED DATA FOR AN INTEREST OUTSTANDING THROUGHOUT EACH PERIOD IS AS FOLLOWS: <Table> <Caption> YEAR ENDED AUGUST 31, 2004 2003 2002 2001 2000 - ---------------------------------------------------------------------------------------------------------------- RATIOS TO AVERAGE NET ASSETS/SUPPLEMENTAL DATA: Total return 10.39% 11.68%(a) (2.20)% 5.15% 8.73% Operating expenses 0.52%(b) 0.57%(b) 0.55%(b) 0.53%(b) 0.55% Interest expense --(c) --(c) 0.03% -- -- Net expenses 0.52%(b) 0.57%(b) 0.58%(b) 0.53%(b) 0.55% Net investment income 4.45%(b) 5.96%(b) 6.42%(b)(d) 8.94%(b) 9.26% Portfolio turnover rate 97% 75% 70% 63% 21% </Table> (a) Total return includes a voluntary reimbursement by the Investment Advisor for a realized investment loss on an investment not meeting the Portfolio's investment restrictions.

These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's and the Portfolio's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States), which require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of investments held at August 31, 2004 by correspondence with the custodian and the banks with whom the Portfolio owns participations in loans, provide a reasonable basis for our opinion.

The Registrant has adopted a code of ethics that applies to the Registrant's principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT. The Registrant's Board of Trustees (the "Board") has determined that James Leary, a member of the Audit Committee of the Board, is an audit committee financial expert as defined by the Securities and Exchange Commission (the "SEC"). Mr. Leary is "independent" as defined by the SEC for purposes of audit committee financial expert determinations. ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES. (a) AUDIT FEES. The aggregate fees billed for each of the last two fiscal years (the "Reporting Periods") for professional services rendered by the Registrant's principal accountant (the "Auditor") for the audit of the Registrant's annual financial statements, or services that are normally provided by the Auditor in connection with the statutory and regulatory filings or engagements for the Reporting Periods, were $9,060 in 2003 and $8,240 in 2004. (b) AUDIT-RELATED FEES. The aggregate fees billed in the Reporting Periods for assurance and related services by the Auditor that are reasonably related to the performance of the audit of the Registrant's financial statements and are not reported under paragraph (a) of this Item 4 were $4,000 in 2003 and $3,500 in 2004. These services consisted of the review of the semi-annual financial statements, and agreed-upon procedures required by lending organizations. The aggregate fees billed in the Reporting Periods for non-audit assurance and related services by the Auditor to the Registrant's investment adviser (not including any sub-investment adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the Registrant ("Service Affiliates") which required pre-approval by the Audit Committee were $0 in 2003 and $0 in 2004 that were reasonably related to the performance of the annual audit of the Service Affiliate. 2 <Page> (c) TAX FEES. The aggregate fees billed in the Reporting Periods for professional services rendered by the Auditor for tax compliance, tax advice and tax planning ("Tax Services") were $2,000 in 2003 and $2,112 in 2004.

NON-AUDIT FEES. The aggregate non-audit fees billed by the Auditor for services rendered to the Registrant, and rendered to Service Affiliates, for the Reporting Periods were $0 in 2003 and $0 in 2004. AUDITOR INDEPENDENCE. The Registrant's Audit Committee has considered whether the provision of non-audit services that were rendered to Service Affiliates which were not pre-approved (not requiring pre-approval) is compatible with maintaining the Auditor's independence. ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS. Not applicable. ITEM 6. SCHEDULE OF INVESTMENTS. Not applicable. ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES. The Registrant has delegated voting of proxies in respect of portfolio holdings to its investment adviser, Highland Capital Management, L.P. ("HCMLP"), to vote the Registrant's proxies in accordance with HCMLP's proxy voting guidelines and procedures. HCMLP has adopted proxy voting guidelines (the "Guidelines") that provide as follows: - HCMLP votes proxies in respect of the Registrant's securities in the Registrant's best interests and without regard to the interests of HCMLP or any client of HCMLP. 3 <Page> - Unless HCMLP's Proxy Voting Committee (the "Committee") otherwise determines (and documents the basis for its decisions) or as otherwise provided below, HCMLP votes proxies in a manner consistent with the Guidelines. - To avoid material conflicts of interest, HCMLP applies the Guidelines in an objective and consistent manner across the Registrant's accounts. Where a material conflict of interest has been identified and the matter is covered by the Guidelines, the Committee votes in accordance with the Guidelines. For the Registrant, where a conflict of interest has been identified and the matter is not covered in the Guidelines, HCMLP will disclose the conflict and the Committee's determination of the matter in which to vote to the Registrant's Board. - HCMLP also may determine not to vote proxies in respect of securities of the Registrant if it determines it would be in the Registrant's best interests not to vote. HCMLP's Guidelines also address how it will vote proxies on particular types of matters such as corporate governance matters, disclosure of executive compensation and share repurchase programs. For example, HCMLP generally will: - Support management in most elections for directors, unless the board gives evidence of acting contrary to the best economic interests of shareholders; - Support proposals seeking increased disclosure of executive compensation; and - Support management proposals to institute share repurchase plans in which all shareholders may participate on equal terms. ITEM 8. PURCHASE OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT INVESTMENT COMPANIES AND AFFILIATED PURCHASERS. Not applicable. ITEM 9. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. The Registrant has a Nominating Committee (the "Committee") of the Board responsible for selecting and nominating persons as members of the Board for election or appointment by the Board and for election by stockholders. The Committee has adopted a Nominating Committee Charter (the "Charter"), pursuant to which the Committee will consider recommendations for nominees from stockholders submitted to the Secretary of the Registrant, Two Galleria Tower, 13455 Noel Road, Dallas, Texas 75240. In evaluating potential nominees, including any nominees recommended by stockholders, the Committee takes into consideration various factors including character and integrity, business and professional experience, and whether the Committee believes the person has the ability to apply sound and independent business judgment and would act in the interest of the Registrant and its stockholders. Submissions must include all information relating to the recommended nominee that is required to be disclosed in solicitations or proxy statements for the election of Board members, as well as information sufficient to evaluate the factors to be considered by the Committee. Submissions must be accompanied by a written consent of the individual to stand for election if nominated by the Board and to serve if elected by the stockholders, and such additional information must be provided regarding the recommended nominee as reasonably requested by the Committee. ITEM 10. CONTROLS AND PROCEDURES. (a) The Registrant's principal executive and principal financial officers have concluded, based on their evaluation of the Registrant's disclosure controls and procedures as of a date within 90 days of 4 <Page> the filing date of this report, that the Registrant's disclosure controls and procedures are reasonably designed to ensure that information required to be disclosed by the Registrant on Form N-CSR is recorded, processed, summarized and reported within the required time periods and that information required to be disclosed by the Registrant in the reports that it files or submits on Form N-CSR is accumulated and communicated to the Registrant's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. (b) There were no changes to the Registrant's internal control over financial reporting that occurred during the Registrant's most recently ended fiscal half-year that have materially affected, or are reasonably likely to materially affect, the Registrant's internal control over financial reporting.
