LETTER TO SHAREHOLDERS ---------------------- IAI CAPITAL APPRECIATION FUND, IAI EMERGING GROWTH FUND, IAI GROWTH FUND, IAI GROWTH AND INCOME FUND, IAI MIDCAP GROWTH FUND, IAI REGIONAL FUND, IAI VALUE FUND OUTLOOK 2000 A summary of the economic outlook as provided by Larry Hill, IAI's Chief Fixed Income Officer, follows. While the U.S. economy continues to show strong growth with modest inflation, concerns that growth cannot continue without igniting inflationary pressures have become widespread. In the last half of the 1990s, corporate mergers and cost reductions have helped to contain wage pressures while a strong dollar, excess capacity, new technology and fierce competition have helped to suppress domestic pricing power. Thus, inflation remains surprisingly benign for the ninth year of an economic expansion. Yet, a shift now appears to be under way. Labor markets are extremely tight. The unemployment rate is at the lowest level in almost 30 years and many firms have been forced to offer bonuses to attract qualified workers. Tight labor markets are threatening to push wage rates, and ultimately inflation, higher. Commodity prices are also in an upswing. Energy prices have vaulted ahead 52% from a year ago. Gold also registered a big move. After languishing below $260 per ounce, gold rocketed to $300 at quarter-end in response to a decision by central bankers to restrict anticipated sales gold over the next 5 years. Other commodities have begun to show signs of acceleration as well during the past few months. The value of the dollar, which had been in a major uptrend for nearly 4 years has weakened in 1999. The strong dollar has had a dampening effect on inflation as U.S. producers have not been able to increase prices in the face of "cheap" imports. Continued growth in Europe, recovery in non-Japan Asia and early signs of life from the Japanese economy suggest that pressure on commodity prices will continue. As excess overseas capacity is absorbed by growth in foreign economies, pricing power may emerge for U.S. companies. While the trend of mega-mergers and cost reductions continues, many of the other elements of the strong growth, modest inflation era of the 1990's have deteriorated. As a result, the Fed is on alert. Policy makers have already moved interest rates higher twice this year and are likely to raise rates again if compelling evidence of slower growth does not materialize. This tightening bias is a threat to financial assets. Another widely discussed unknown for the financial markets is the potential impact of Y2K. The financial services industry has taken significant steps to test trading, settlement and other systems for Y2K compliance. However, broker 2

This will have an impact on liquidity in the markets. Couple this with the probable pre-funding of needs by fixed income borrowers prior to Y2K and the markets are likely to remain volatile through the remainder of the year. In our view, the Federal Reserve's actions will have an impact on growth in the economy. Early indications suggest that rate increases are having an impact as housing starts have softened in response to higher mortgage rates. As this works itself through the broader economy, activity will slacken. A recession, however, remains only a remote possibility. Slowing economic growth and a modest increase in inflation implies a continuation of this aging economic recovery into the year 2000.

FUND MANAGER'S REVIEW --------------------- IAI CAPITAL APPRECIATION FUND IAI CAPITAL APPRECIATION FUND FUND MANAGEMENT IAI SMALL CAP/ MIDCAP TEAM CURT D. MCLEOD, CFA SCOTT A. BILLEADEAU, CFA ROBERT E. SCOTT, CFA ROBERT J. MLNARIK TOP FIVE SECTORS % OF NET ASSETS AS OF 9/30/99 [BAR CHART] TECHNOLOGY SERVICES 18.4% ELECTRONIC TECHNOLOGY 14.1% FINANCIAL 13.1% COMMERICAL SERVICES 8.4% CONSUMER DURABLES 6.1% * PERCENTAGE OF NET ASSETS AS OF 9/30/99. HOW HAS THE FUND PERFORMED? For the past six months the returns were 7.48% for the IAI Capital Appreciation Fund, 12.75% for the Russell 2500 Growth Index and 0.36% for the S&P 500 Index. WHICH HOLDINGS WERE PARTICULARLY SUCCESSFUL FOR THE FUND? WERE THERE ANY DISAPPOINTMENTS? Our healthcare stocks were among the strongest contributors to performance in the past six months. Leading the way were Mentor Corp. (4.7%)* and Xomed Surgical Products. The financial and consumer cyclical sectors were the weakest performing sectors in the Fund. Although technology fared well during the past six months, our technology holdings declined as a group. International Telecommunications Data Systems (ITDS) (1.5%)*, Inspire Insurance Solutions (0.8%)*, and Billing Concepts all experienced deteriorating fundamental conditions. WERE THERE ANY SIGNIFICANT CHANGES? Portfolio activity was higher than normal during the past six months as we exerted our strict sell discipline and eliminated a number of companies including Xomed Surgical Products, Barnett Inc., Billing Concepts, Flanders, Sinclair Broadcasting and Watsco. We also made a number of new additions to the Fund including Wild Oats Markets (2.6%)*, 99 Cents Only Stores (2.6%)*, Papa John's International (2.1%)*, JAKKS Pacific (0.8%)*, Renal Care Group (2.3%)*, DSET Corp. (1.6%)*, Mercury Computer Systems (1.6%)*, REMEC (1.5%)*, and Sawtek (2.2%)*. CAN YOU POINT TO ANY SPECIFIC MARKET FACTORS THAT INFLUENCED THE FUND'S PERFORMANCE? Indications of a stronger economy helped boost small caps in the first half of the period, in particular those stocks with strong price momentum. Earnings-based valuation appeared to have lost most of its relevance. As inflation concerns took center stage during the last three months the Federal Reserve engineered two interest rate increases over the summer. With that backdrop, the market sold off and impacted both small and large cap stocks equally, with each index declining (6.3%) as measured by the Russell 2000 and S&P 500, respectively. WHAT IS YOUR OUTLOOK FOR THE FUND? We continue to be encouraged about the long-term outlook for the small cap market. We believe that the increased acquisition activity within the small cap market illustrates the tremendous value in the stocks of small companies. Earnings growth in general continues to be strong as the domestic economy continues to grow. Interest rate fears notwithstanding, we believe small cap stocks offer one of the most attractive market opportunities. 4

SCOTT, CFA ROBERT J. MLNARIK TOP FIVE COMMON STOCK SECTORS % OF NET ASSETS AS OF 9/30/99 [BAR CHART] ELECTRONIC TECHNOLOGY 23.2% TECHNOLOGY SERVICES 23.0% HEALTH SERVICES 8.3% RETAIL TRADE 6.8% CONSUMER SERVICES 6.0% * PERCENTAGE OF NET ASSETS AS OF 9/30/99. HOW HAS THE FUND PERFORMED? The IAI Emerging Growth Fund showed a return of (0.95%) for the past six months, as compared to the Russell 2500 Growth 12.75% and the S&P 500 Indices 0.36% respectively. WHICH HOLDINGS WERE PARTICULARLY SUCCESSFUL FOR THE FUND? WERE THERE ANY DISAPPOINTMENTS? Technology and consumer stocks helped the Fund's performance as Peregrine Systems (2.8%)*, Sawtek (2.6%)*, Legato Systems (1.5%)* and Navigant Consulting (2.5%)*, posted sharp gains. Tut Systems (1.5%)*, a significant holding of the Fund in the past six months, detracted from performance as restricted holders of the stock were finally allowed to sell, putting downward pressure on the share price. WERE THERE ANY SIGNIFICANT CHANGES? We were able to reduce our position in Tut Systems from approximately 30% of the Fund down to under 2% as the restrictions on the stock were lifted. This sale resulted in a significant gain for the Fund's shareholders since our initial investment in the company. We put the proceeds from the Tut sale to work in several technology stocks including Creo Products (1.4%)*, Tollgrade Communications (2.9%)*, DII Group (2.9%)* and Mastech Corp. (1.9%)*. CAN YOU POINT TO ANY SPECIFIC MARKET FACTORS THAT INFLUENCED THE FUND'S PERFORMANCE? The period witnessed substantial volatility with strong performance exhibited the first half as small caps led the market advance. However, the equity markets sold off across the board during the second half of the period as two short-term interest rate hikes by the Federal Reserve took hold. The Fed has moved to a tightening bias as it wants to be vigilant in heading off future inflation. WHAT IS YOUR OUTLOOK FOR THE FUND? We are seeing signs that sustainable, strong near-term relative performance for small cap stocks could be close at hand. Over the last six months, small cap stocks have outperformed their larger cap counterparts. This recent trend is a reversal of the large cap leadership that has been in place for the last several years. We also believe that the increased acquisition activity within the small cap market illustrates the tremendous value in the stocks of small companies and bodes well for this segment of the market. 6

Although over 50% of the Fund's holdings outperformed the market during the past six months, the numbers were insufficient to offset poor showings in a few large holdings, namely Bergen Brunswig, Republic Services Group and Waste Management, which were eliminated. A downward revision in earnings expectations was the catalyst in all three cases. On the positive side of the ledger, technology was the largest contributor to returns. The best performing stocks were Patterson Dental (3.9%)*, BMC Software (3.2%)* and Comverse Technology (1.9%)*. WERE THERE ANY SIGNIFICANT CHANGES? Transaction activity was skewed more toward the sell side, with eight positions eliminated due to either achieving our price targets or deteriorating fundamentals. Positions eliminated in addition to those mentioned above include Abbott Laboratories, Clorox, Fiserv, Galileo International, Gillette and Xerox. Positions were initiated in two stocks: Citrix (1.1%)* and Electronic Arts (1.9%)*. CAN YOU POINT TO ANY SPECIFIC MARKET FACTORS THAT INFLUENCED THE FUND'S PERFORMANCE? Mounting inflationary pressures prompted the federal reserve Board to raise interest rates, sparking a correction in financial markets. The S&P 500 index was flat, with interest sensitive and cyclical stocks faring the worst. WHAT IS YOUR OUTLOOK FOR THE FUND? We remain cautious on the market as interest rates are biased upwards, which is likely to preclude any meaningful upside moves. Although domestic Y2K related risks appear more manageable than earlier believed, risks do remain. As we move beyond the new year, we believe that interest rates will flatten out and returns will reflect growth in corporate earnings. This suggests returns more in line with historic norms of low double digits. 8

FUND MANAGER'S REVIEW --------------------- IAI GROWTH AND INCOME FUND IAI GROWTH AND INCOME FUND FUND MANAGEMENT IAI LARGE CAP TEAM KEITH WIRTZ, CFA DAVID A. MCDONALD JEFF MALET PAUL ROACH TOP FIVE COMMON STOCK SECTORS % OF NET ASSETS AS OF 9/30/99 [BAR CHART] FINANCIAL 19.1% UTILITIES 15.6% PRODUCER MANUFACTURING 10.4% CONSUMER DURABLES 7.8% HEALTH SERVICES 7.3% * PERCENTAGE OF NET ASSETS AS OF 9/30/99. HOW HAS THE FUND PERFORMED? The return for the past six months for the IAI Growth and Income Fund was (2.9%), compared to the S&P 500 Index return of 0.36%. WHICH HOLDINGS WERE PARTICULARLY SUCCESSFUL FOR THE FUND? WERE THERE ANY DISAPPOINTMENTS? Specific stocks performing well were two Communications Services companies Bell Atlantic (3.3%)* and SBC Communications (2.6%)* Communication Services companies continue to benefit increase traffic via the Internet and industry consolidation. The worst performing stocks during the past six months were Newell Rubbermaid (1.3%)* and United Healthcare Corp. (2.1%)*. Newell Rubbermaid stock continues to be under pressure due to a slower than anticipated integration of the merger of Newell and Rubbermaid. United Healthcare stock was hurt by the increased likelihood of negative legislation coming out Washington regarding Health Maintenance Organizations. CAN YOU POINT TO ANY SPECIFIC MARKET FACTORS THAT INFLUENCED THE FUND'S PERFORMANCE? For most companies, the strength of the economy is the major determining factor as to how fast a company can grow their business and thus their free cashflow/earnings. It is difficult to imagine overall economic activity picking up meaningfully from current strong levels without a corresponding increase in inflation causing the Federal Reserve to increase interest rates further. At current stock prices, we believe relatively strong growth is already priced in most stocks, leaving interest rates as the primary variable that will determine future stock prices. WHAT IS YOUR OUTLOOK FOR THE FUND? Valuations remain high even after the declines experienced over the last few months. If anything has changed in the recent past it is that market sentiment/psychology has started to turn decidedly cautious if not negative. It is our belief, given the high valuation level of stocks, that there is little room for stocks to move meaningfully higher on strong business fundamentals alone. Interest rates must at a minimum stabilize and probably need to go lower for stocks to be significantly higher by year end. While we have no strong conviction as to the future direction of interest rates, we will continue to try to find stocks that have strong business fundamentals that are not reflected in the price of the stock and thus have a built in margin of safety should interest rates continue to rise. 10

FUND MANAGER'S REVIEW --------------------- IAI MIDCAP GROWTH FUND IAI MIDCAP GROWTH FUND FUND MANAGEMENT IAI SMALL CAP/ MIDCAP TEAM CURT D. MCLEOD, CFA SCOTT A. BILLEADEAU, CFA ROBERT E. SCOTT, CFA ROBERT J. MLNARIK TOP FIVE COMMON STOCK SECTORS % OF NET ASSETS AS OF 9/30/99 [BAR CHART] ELECTRONIC TECHNOLOGY 23.4% TECHNOLOGY SERVICES 12.2% COMMERCIAL SERVICES 11.5% HEALTH TECHNOLOGY 10.0% RETAIL TRADE 8.6% * PERCENTAGE OF NET ASSETS AS OF 9/30/99. HOW HAS THE FUND PERFORMED? The past six months showed a return of 2.0% on the IAI Midcap Growth Fund compared with the S&P 500 showing a return of 0.36%, the S&P Midcap's return of 4.57% and the S&P Midcap Growth's return of 5.55%. WHICH HOLDINGS WERE PARTICULARLY SUCCESSFUL FOR THE FUND? WERE THERE ANY DISAPPOINTMENTS? Technology again was one of the leading sectors in the market driven by strong earnings growth. Within technology, Navigant Consulting (2.8%)*, a leading consultant to the utility industry, was the top performer, rising nearly 70%. Legato Systems (2.6%)* and Veritas Software (1.9%)*, also contributed strongly to performance. We had a few healthcare companies report disappointing earnings, including Health Management (1.1%)*, Quintiles (.38%)*, and Total Renal Care (0%)*. WERE THERE ANY SIGNIFICANT CHANGES? With regards to transaction activity during the past six months, we eliminated Keane, Republic Services, Starbucks, and Total Renal Care due to announced earnings shortfalls. We eliminated our position in Qualcomm, taking profits in one of our biggest contributors to performance this year. We added only one new investment in the Fund, Papa John's International (1.6%)*, a leading operator of pizza delivery and carryout restaurants. CAN YOU POINT TO ANY SPECIFIC MARKET FACTORS THAT INFLUENCED THE FUND'S PERFORMANCE? The past six months were a volatile period for the Fund. The first three months saw strong performance as small and midcap stocks led the market advance. Both the S&P Midcap Index and the Russell 2000, with a gain of 15.6% doubled the 7.1% return of the S&P 500 index. However, as the impact of two short-term interest rate increases by the Federal Reserve during the last three months took hold, the market surrendered approximately half of its earlier gains. Only two sectors, technology and utilities, posted positive returns. The interest rate sensitive sectors were the hardest hit. WHAT IS YOUR OUTLOOK FOR THE FUND? While the near-term outlook for the market is somewhat uncertain due to the current negative interest rate environment and as the market prepares for the uncertainties surrounding any Y2K impact, we believe the longer-term outlook for the midcap sector is quite positive. We think as the market broadens out from the leading mega-cap growth companies, which have been the performance leaders over the last few years, the midcap sector will benefit. Furthermore, valuations for midcap stocks continue to be very attractive versus large cap stocks. 12

FUND MANAGER'S REVIEW --------------------- IAI REGIONAL FUND IAI REGIONAL FUND FUND MANAGEMENT IAI REGIONAL TEAM JULIAN P. "BING" CARLIN, CFA AMY DENN TOP FIVE COMMON STOCK SECTORS % OF NET ASSETS AS OF 9/30/99 [BAR CHART] HEALTH TECHNOLOGY 14.3% PROCESS INDUSTRIES 8.8% RETAIL TRADE 7.7% UTLITIES 7.5% ELECTRONIC TECHNOLOGY 6.6% * PERCENTAGE OF NET ASSETS AS OF 9/30/99. HOW HAS THE FUND PERFORMED? The IAI Regional Fund showed a return of 5.99% over the last six months compared to the S&P 500's 0.36% return. WHICH HOLDINGS WERE PARTICULARLY SUCCESSFUL FOR THE FUND? WERE THERE ANY DISAPPOINTMENTS? Performance was led by Recovery Engineering, a Minneapolis company that makes water filtration systems. Proctor & Gamble announced they would initiate a tender offer for $35.25/share, a price representing a premium of approximately 100% above Recovery's current stock price. Although Financials was an underperforming sector due to rising interest rates, our position in Chicago Title, the nation's third largest title company, appreciated significantly on news that they would be acquired by Fidelity National Financial. Both positions were eliminated after the announcement. Biomet and Spyglass were the biggest detractors from performance and were eliminated from the Fund. WERE THERE ANY SIGNIFICANT CHANGES? Several stocks were added to the Fund during the third quarter, including General Electric (2.4%)*, Minnesota Mining & Manufacturing (1.7%)*, Anheuser-Busch (2.1%)*, General Mills (2.4%)*, Exxon (2.5%)*, TCF Financial (2.0%)*, Lucent Technologies (2.1%)* and Time Warner (1.5%)*. Among the stocks eliminated from the Fund were Ecolab, AT&T Corp., Tootsie Roll Industries, Allstate and Galileo International. The cash position of the Fund remained at above-normal levels. CAN YOU POINT TO ANY SPECIFIC MARKET FACTORS THAT INFLUENCED THE FUND'S PERFORMANCE? The past six months continued in the negative direction that the market has been in since April with 65% of stocks showing negative returns for 1999. Performance has reflected this trend and we continue to fight a defensive investment battle. A handful of stocks have masked the problem and driven the NASDAQ Index higher. These investments have centered on Internet and high-tech companies whose valuations are extremely lofty and stock prices appear extended. We have refused to play in this sector due to its high valuation risk. WHAT IS YOUR OUTLOOK FOR THE FUND? As we work our way through the fourth quarter, we will be looking for investment targets with more reasonable valuations. We continue to focus on (1) aging of America, (2) globalization and (3) technology/productivity as major investment themes. One segment of technology that we are currently invested in is telecommunications. We believe that wireless and broadband infrastructure will continue to play an important role in the coming years. We hope the next six months will prove to be more favorable for investors than the past six months, but our guard remains alert! 14

FUND MANAGER'S REVIEW --------------------- IAI VALUE FUND IAI VALUE FUND FUND MANAGEMENT IAI SMALL CAP/ MIDCAP TEAM CURT D. MCLEOD, CFA SCOTT A. BILLEADEAU, CFA ROBERT E. SCOTT, CFA ROBERT J. MLNARIK TOP FIVE COMMON STOCK SECTORS % OF NET ASSETS AS OF 9/30/99 [BAR CHART] PRODUCER MANUFACTURING 14.6% HEALTH SERVICES 13.1% CONSUMER DURABLES 11.2% ELECTRONIC TECHNOLOGY 10.7% TECHNOLOGY SERVICES 8.8% * PERCENTAGE OF NET ASSETS AS OF 9/30/99. HOW HAS THE FUND PERFORMED? For the past six months the return for the IAI Value Fund was (29.08%) as compared to the Russell 2500 Growth Index's return of 12.75% and the S&P 500's return of 0.36%. WHICH HOLDINGS WERE PARTICULARLY SUCCESSFUL FOR THE FUND? WERE THERE ANY DISAPPOINTMENTS? The Fund underperformed in the past six months primarily due to the performance of its two largest holdings, Tut Systems and Pathnet PFD, which were eliminated. Positive performers during the past six months were First Health (2.6%)* and CompX (3.5%)*. First Health group announced a strong list of new clients and CompX made an acquisition which should enhance its growth prospects. WERE THERE ANY SIGNIFICANT CHANGES? There were significant changes during the past six months. The large positions in Pathnet PFD and Tut Systems were eliminated and 16 new stocks were added. The Tut Systems sale resulted in a significant gain for Fund shareholders since our initial investment in the company. CAN YOU POINT TO ANY SPECIFIC MARKET FACTORS THAT INFLUENCED THE FUND'S PERFORMANCE? The relatively strong performance of growth stocks had an impact on the fund. The Russell 2500 Growth Index returned 8.89% during the past six months vs. the Russell 2500 Value Index performance of 6.00%. The Fund's emphasis on valuation was not beneficial during the last six months. WHAT IS YOUR OUTLOOK FOR THE FUND? We suspect changes in economic conditions, Federal Reserve policy and market psychology will continue to result in volatile short-term market performance. Changes in the market sentiment does not change our focus.

NOTES TO FINANCIAL STATEMENTS ----------------------------- IAI CAPITAL APPRECIATION FUND, IAI EMERGING GROWTH FUND, IAI GROWTH FUND, IAI GROWTH AND INCOME FUND, IAI MIDCAP GROWTH FUND, IAI REGIONAL FUND, IAI VALUE FUND SEPTEMBER 30, 1999 (UNAUDITED) [1] SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The IAI Mutual Funds are registered under the Investment Company Act of 1940 (as amended) as diversified, open-end management investment companies, or series thereof. IAI Capital Appreciation Fund (Capital Appreciation), IAI Emerging Growth Fund (Emerging Growth) and IAI Midcap Growth Fund (Midcap Growth) are separate portfolios of IAI Investment Funds VI, Inc., IAI Growth Fund (Growth Fund) is a separate portfolio of IAI Investment Funds II, Inc., IAI Growth and Income Fund (Growth and Income Fund) is a separate portfolio of IAI Investment Funds VII, Inc., IAI Regional Fund (Regional Fund) is a separate portfolio of IAI Investment Funds IV, Inc. and IAI Value Fund (Value Fund) is a separate portfolio of IAI Investment Funds VIII, Inc. The Funds have a primary objective of long-term appreciation through investment in equity securities. Significant accounting policies followed by the Funds are summarized below: SECURITY VALUATION Portfolio securities are valued at the close of the New York Stock Exchange on each trading day. Listed and unlisted securities for which such information is regularly reported are valued at the last sale price of the day or, in the absence of sales, at values based on the closing bid or the last sale price on the prior trading day. Long-term and short-term "non-money market" debt securities are valued by a portfolio pricing service. Securities which cannot be valued by the portfolio pricing service are valued using dealer-supplied valuations, or are valued under consistently applied procedures established by the Board of Directors to determine fair value in good faith. Short-term "money market type" debt securities having a remaining maturity of 60 days or less at acquisition are valued at cost adjusted for amortization to maturity of any premium or discount. Restricted securities for which there is no public market are valued at fair value in good faith under procedures established by the Board of Directors. Such procedures consider various factors including, but not limited to, the cost of the security at the date of purchase, the current financial statements of the issuer and special reports prepared by analysts, the size of the position held, recent purchases or sales of securities of the company, prices and public trading activity of comparable companies, prices of unrestricted securities of the same class discounted to reflect the nature and duration of restrictions on disposition, pending public offerings with respect to the security, changes in economic conditions and industry developments affecting the issuer, and other relevant matters. Restricted securities represent $1,465,601 (2.8% of net assets) for Emerging Growth, $787,853 (2.2% of net assets) for Growth and Income Fund, $3,202,302 (1.6% of net assets) for the Regional Fund and $440,335 (6.2% of net assets) for Value Fund. Because of the inherent uncertainty of valuation, those estimated values may differ significantly from the values that would have been used had a ready market for the securities existed, and the differences could be material. FUTURES AND OPTIONS CONTRACTS In order to increase exposure to and hedge against changes in the market, the Funds may buy and sell futures contracts and options. The risks of entering into future and option contracts include the possibility that changes in the value of these contracts may not correlate with changes in the underlying security. Futures contracts are valued at the settlement price of the exchange on which they are traded. Upon entering into a futures contract, a Fund is required to deposit either cash or securities, representing the initial margin, equal to a certain percentage of the contract value. Subsequent changes in the value of the contract or variation margin, are recorded daily as unrealized gains or losses. The variation margin is paid or received in cash daily by the Fund. The Fund will realize a gain or loss upon expiration or closing of the option transaction. 55

NOTES TO FINANCIAL STATEMENTS ----------------------------- IAI CAPITAL APPRECIATION FUND, IAI EMERGING GROWTH FUND, IAI GROWTH FUND, IAI GROWTH AND INCOME FUND, IAI MIDCAP GROWTH FUND, IAI REGIONAL FUND, IAI VALUE FUND SEPTEMBER 30, 1999 (UNAUDITED) [1] SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT.) When an option is exercised, the proceeds on sales for a written call option, the purchase cost for a written put option or the cost of a security for a purchased put or call option is adjusted by the amount of premium received or paid. FEDERAL TAXES Since it is each Fund's policy to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to its shareholders, no provision for income taxes is required. In order to avoid the payment of any federal excise taxes, the Fund is required to distribute substantially all of its net investment income and net realized gains on a calendar year basis. Distributions in excess of book basis net investment income (but which are not tax returns of capital) are presented as "excess distributions" in the statement of changes in net assets and the financial highlights. Net investment income and net realized gains differ for financial statement and tax purposes primarily because of recognition of limited partnership income and the deferral of "wash sale" losses for tax purposes. The character of distributions made during the year from net investment income or net realized gains may also differ from its ultimate characterization for tax purposes. SECURITY TRANSACTIONS AND INVESTMENT INCOME The Funds record security transactions on trade date, the date the securities are purchased or sold. Dividend income is recorded on the ex-dividend date. Interest Income is recorded on the accrual basis. The Funds amortize discount purchased on long-term bonds using the level yield method of amortization. Security gains and losses are determined on the basis of identified cost, which is the same basis used for federal income tax purposes. The Funds use the equity method of accounting for limited partnerships. DISTRIBUTIONS TO SHAREHOLDERS Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income are paid semi-annually. Capital gains, if any, are primarily distributed as of the end of the calendar year. Additional capital gains distributions as needed to comply with federal tax regulations are distributed during the year. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts in the financial statements. Actual results could differ from those estimates. [2] COMMITMENTS AND CONTINGENCIES INSURANCE For purposes of obtaining certain types of insurance coverage for the Funds and its officers and directors, the Funds are policyholders in an industry-sponsored mutual insurance company (the Company). In connection with their obligations as policyholders, the Funds are committed to make capital contributions, if requested by the Company. LITIGATION In July 1998, a lawsuit was filed against Value Fund, Advisers and certain of their officers and directors relating to the pricing of a restricted security held by the Fund. Management, after review with legal counsel, believes the ultimate disposition of this matter will not have a material effect on the Fund's financial condition. LIMITED PARTNERSHIP COMMITMENTS At September 30, 1999, the Regional Fund is committed to invest an additional $613,000 in Spell Capital Partners Fund I limited partnership. Default by a limited partner of payment of a properly requested capital contribution, other than default due to a legal determination that such contribution need 56

The Fund's management intends to finance the aforementioned commitment with available cash or with proceeds from the sale of investments in short-term securities. The Fund maintains in a segregated account an amount equal to the aggregate unpaid commitments. [3] FEES AND EXPENSES Under terms of each Fund's Management Agreement, Investment Advisers, Inc. (Advisers) is required to pay for all expenses of each Fund, except certain costs (primarily those incurred in the purchase and sale of assets, taxes, interest and extraordinary expenses), in return for each Fund paying an all inclusive management fee (unified fee) to Advisers. The fee is equal to an annual rate of 1.25% (1.40% for Capital Appreciation) declining to 1.10% (1.00% for Growth and 1.00% for Growth and Income Fund) of average daily net assets. This fee is paid monthly. The Management Agreements further provides that Advisers will reimburse the Funds for the fees and expenses it pays to Directors who are not "interested persons" of the Funds or reduce its fee by an equivalent amount. [4] CAPITAL STOCK The Funds have authorized 10 billion shares of $.01 par value stock.
