VALUE REPORT



Dear Investor

[Photo of Bill Nasgovitz]

The excitement of the holidays has subsided. It is time for us to reflect on the
year gone by and some of the lessons we have learned. In 1997, we were reminded
that overvalued stocks can become even more overvalued when passion rather than
prudence rules the day. We learned that a new generation of investors has
dismissed the collective wisdom of their elders and proclaimed a new golden age
for equities. We have realized that investors are so conditioned to buying
stocks on market dips that they are prone to ignore the economic fundamentals
that support equities valuations. Have these lessons inspired us to change our
investment philosophy and methodology? Hardly. In fact, we remain totally
committed to the principles of value investing that have guided us since
inception.

For those who may be tempted to abandon these principles and take up the mantra
of new age investing, I want to share the resolutions that I and every member of
the Heartland investment team reaffirm each and every new year.

1. I will look down as well as up in making investment decisions--endeavoring to
   assess risk as diligently as reward potential.

2. I will take the long view--realizing that short-term market trends are often
   the product of investor emotion, not reason.

3. I will focus on value--stocks that we believe are priced realistically
   relative to their "real world" economic value.

4. I will acknowledge the beneficial role bonds can play in a diversified
   investment portfolio.

5. I will be my own person--recognizing that consensus wisdom is often wrong.

If you stick to these resolutions, I believe you will prosper in what may be a
very challenging investment environment in 1998. 

If we are to continue to enjoy the "best of all possible worlds" for equity
investing--low inflation, low interest rates and strong corporate earnings
growth--perhaps for the time being, at least, high equity valuations are
justified. The issue is whether there is anything lurking out there to disrupt
this comfortable scenario. Due in part to the problems in Asia--devalued
currencies will likely increase low cost imports to the U.S., putting downward
pressure on domestic product pricing in the process--inflation is likely to
remain low. Consequently, we believe interest rates should stay low and probably
trend even lower in the year ahead.

But, what about earnings? The market seems to believe American companies will
continue to grow earnings at an 8-10% annual rate forever. We doubt it. In fact,
we think S&P earnings estimates for 1998 will prove to be optimistic. With U.S.
labor costs rising and, as aforementioned, pricing flexibility severely
restricted by cheap imports from Asia, corporate profit margins are likely to
suffer. I don't believe we can count on the kind of productivity

                                                                    VALUE REPORT


gains that have allowed companies to increase earnings at 2 to 3 times revenue
growth in recent years. If, as we anticipate, earnings fall well short of
consensus expectations, we could see a very substantial correction in stocks
that could last for more than just a few weeks.

Should investors sell all their stocks and equity mutual funds in anticipation
of a market correction? We don't think so. We do think investors would be
prudent to gravitate to individual stocks and equity mutual funds that offer
value as measured by time tested fundamental yardsticks such as low
price/earnings, low price/cash flow and low price/book value ratios. We also
believe they should consider bonds and bond funds. Today, you can make a
compelling case for bonds based solely on their own fundamental merits. In view
of what we see as the substantial risk in equities, bonds may currently be an
appealing alternative to stocks as well. It is worth noting that legendary
equity investor and fellow Graham & Dodd disciple, Warren Buffett, reportedly
bought several billions of dollars of zero coupon Treasury Bonds this Fall. We
don't know if neighbor Warren is still bullish on bonds, but he has
traditionally been a "buy and hold" type investor.

In our individual fund reports, we present examples of our investment selection
process. We hope you find them informative illustrations of our value oriented
discipline. Be advised, however, as with all our portfolio holdings, we
continuously monitor developments and reserve the right to change our views and
look for different opportunities.

In closing, over the last several years, stocks have delivered astounding
returns. We are delighted to have substantially enhanced our equity fund
shareholders' assets. We believe we will face a much sterner challenge in the
year ahead, but look forward to the opportunity to demonstrate the effectiveness
of our value discipline.

Warmest Regards,



William J. Nasgovitz
President

VALUE REPORT


Heartland Large Cap Value Fund



In full year 1997, the Fund returned 22.9% versus the S&P 500's 33.4% advance.
In fourth quarter 1997, the Fund declined 2.7% compared to the Standard & Poor's
500 Index's 2.9% gain. For more information on the Fund, including top ten
holdings, please see the Fund Fact Sheet on page 14.

In 1997, our financial holdings led the performance parade. Insurance stocks did
well and, we believe, will continue to contribute to returns in the year ahead.
Our bank stocks also boosted performance; however, due in our opinion to fairly
rich valuations, we have largely eliminated them from the portfolio. The Asian
economic crisis short-circuited earlier gains in cyclical stocks, which had
performed well until falling out of bed in the fourth quarter. El Nino dampened
returns from the energy sector. The Fund's substantial cash position--15%-20%
through most of 1997, and 23% going into the fourth quarter--restrained returns.
Comparisons to our S&P 500 benchmark were also made more difficult by the
particularly strong gains made by the "favored fifty" type growth stocks that
have such a disproportionate impact on the Index.

Sharp market corrections in late October and December gave us the opportunity to
deploy our substantial cash reserves. By year-end 1997, the Fund was nearly
fully invested. We added to our positions in energy stocks, which, in our view,
were unduly punished by investors' response to El Nino--a classic example of
overreaction to a short-term, random event. We are still consuming more energy
than we are producing. Longer term, this should be favorable for energy prices
and energy stock earnings. We also added to our positions in cyclicals, which,
as aforementioned, sold off due to concern over Asian economic weakness. We
believe

renewed economic momentum in Europe will help fill the void being created by the
downturn in Asia and that the earnings for cyclicals like paper companies will
surprise on the upside. We also beefed up positions in the deeply depressed
hospital and HMO stocks. We believe all the bad news is already built into
current stock prices and that the economics in these industries will improve in
1998.

Welcome Kmart Shoppers

Kmart has had its problems in recent years. However, we believe new management
is making progress with its sustained program to re-invigorate sales and improve
profit margins. The stock should be a beneficiary rather than a victim of Asian
economic problems, as the cost of goods imported from Asia declines. At year-end
1997, Kmart stock was trading at just 17% of sales, a substantial discount from
the retail group average, and at a rather modest 10% premium to book value.
Kmart has a price/earnings ratio of about 13 times our 1998 estimates and a
price/cash flow ratio of about 5.3 times our '98 projections. We will keep an
eye on management to see if our positive assessment is accurate, but we think
the stock is still too cheap for a company we believe is turning around.

Heartland Mid Cap Value Fund



In full year 1997, the Fund returned 22.8% versus the S&P Mid-Cap's 32.3%
advance. In fourth quarter 1997, the Fund declined 2.4% compared to the S&P
Mid-Cap Index's 0.8% gain. For more information on the Fund, including top ten
positions, please see the Fund Fact Sheet on page 15.

In 1997, the Fund's insurance company and bank holdings performed particularly
well. We are maintaining our positions in the insurers, but taking some profits
in bank stocks that we believe have become richly priced. Home builders, food
retailers and entertainment holdings also performed well. We continue to see
selected value in these groups.

Our holdings in cyclical companies, particularly the base metals like copper and
aluminum, disappointed. Investors appeared to recognize that weakness in Asian
economies would likely result in reduced demand and lower prices for the metals.
We think they are right, but that this will be a relatively temporary
phenomenon. As Asian countries attempt to export their way out of the current
economic malaise, we believe demand and base metals prices will recover.
Consequently, we are adding to positions in stocks we feel are very cheap
relative to longer-term prospects.

The Fund's median capitalization of approximately $1.3 billion compared to about
$2.8 billion for the S&P Mid-Cap Index also worked against us, as larger
mid-cap companies tended to outperform their smaller counterparts. We still are
finding more fundamental values in smaller mid-cap companies. In the year ahead,
we believe other investors will as well.

There's No Business Like Show Business

King World Productions is one of the leading syndicators of television
programming, with an impressive roster that includes The Oprah Winfrey Show,
Wheel of Fortune, and The New Hollywood Squares. The stock got hit hard when it
was rumored that Oprah was going to hang up her microphone to direct and act in
more movies. We bought the stock shortly after Oprah announced she would
continue with the show.

King World stock has recovered nicely, rebounding from a 1997 low below $35 per
share to $57.75 at year-end 1997. On January 19, 1998 shareholders approved a
2-for-1 stock split. We think it still represents value. Prices for leading
syndicated programming are trending up. We expect King World's earnings will as
well. The company has a rock-solid balance sheet featuring around $370 million
in cash. Oprah owns 5% and the King family, including the Chairman and CEO, owns
around 20%. So, management and leading talent should be motivated to keep the
show on the road. At year-end 1997, King World stock was trading at around 14
times our 1998 earnings estimates and at around 2.6 times book value. Of course,
we'll stay tuned to developments, but for now, that is an attractive enough
value to keep us from changing the channel.

"Barbelling our portfolio provided a total return advantage over concentrating
investments in intermediate term Treasuries."

In full year 1997, the Fund returned 9.7% versus the benchmark index's 7.7%
advance. In fourth quarter 1997, the Fund returned 3.4% compared to the Lehman
Intermediate Term Treasury Index's 2.2% gain.

Declining interest rates along the yield curve buoyed bond returns in 1997. In
fourth quarter 1997, investors' "flight to quality" from a highly volatile stock
market benefited Treasury securities in particular, with yield spreads to
corporates widening due, in our opinion, to developing concerns over the impact
the Asian crisis would have on corporate earnings and balance sheets.
Consequently, our decision earlier this year to eliminate corporate bonds from
the Fund's portfolio proved advantageous.

Our decision to limit interest rate risk by keeping the Fund's average portfolio
duration between 3 to 6 years might have restrained returns, as the long end of
the government bond market performed spectacularly well. However, we had
"barbelled" the portfolio, with heavy weightings in longer term bonds at one end
and short term mortgage agencies with higher yields than short term Treasuries
on the other. This strategy provided a total return advantage over concentrating
investments in intermediate term Treasuries.

As of year-end 1997, the Fund has approximately 60% of its assets in short and
intermediate duration Government Agency mortgage bonds. While mortgage bonds are
subject to prepayment risk, they provide a significant yield advantage over
similar duration Treasuries.

Looking ahead to 1998, we think interest rates will continue to trend down,
albeit not immediately and not as dramatically as in 1997. The federal budget
deficit is shrinking and some economists are forecasting a budget surplus in
1998. U.S. government securities still have a yield advantage over bonds from
other

developed nations--somewhat confounding in that America has the lowest deficit
to Gross Domestic Product of the G7 nations. So, we think foreign investment
will continue to be strong. Declining issuance of U.S. government bonds may also
result in a "scarcity" premium.

With our favorable outlook for the bond market, increasing volatility in the
stock market as growth stocks blow up on a regular basis, and certain foreign
markets offering all the safety of a minefield, we believe prudent investors
should consider allocating a larger portion of their assets to U.S. government
bond funds.

Oh Give Me a Home

As investors spooked by the volatile stock market stampeded into Treasuries,
prices took off. As value investors, we saw where the herd was heading and went
to an alternative water hole--non-callable Federal Home Loan Bank bonds. Our
reasoning was that, as Treasuries became more fully priced, some of the
buffaloes would seek value elsewhere. We were already sipping at this higher
yielding spring when they arrived. So, the portfolio got a yield boost and some
attractive capital appreciation as well as other investors dipped in.

"We believe high-yielding stocks such as utilities and REITs may be a safe
port in a market storm."

In full year 1997, the Fund returned 30.6% versus the Russell 2000 Index's 22.4%
advance. In fourth quarter 1997, the Fund returned 2.3% compared to the Russell
2000 Index's decline of 3.3%. For more information on the Fund, including top
ten positions, please see the Fund Fact Sheet on page 17.

Value Plus really lived up to its name in 1997. Thirteen portfolio holdings were
taken over. It appears strategic corporate buyers are value investors as well.
Our financial stocks, including Real Estate Investment Trusts (REITs) performed
quite well, as did our substantial utilities holdings, with investors appearing
to recognize that deregulation may prove to be a blessing instead of a curse. We
also saw some nice moves in convertible preferred and convertible bond holdings.
It is hard to single out any industry group of any size in the portfolio that
truly disappointed. Our investment in Amway Asia Pacific Ltd. was premature and
we sold out at a loss. Also, several small positions in South African gold
mining stocks are presently underwater, but we believe they can do better in the
year ahead, if gold regains some of its glitter.

We believe that high-yielding groups like utilities and REITs, which together
represented about 24% of the Fund's net assets at year-end 1997, will contribute
to performance in the year ahead. We don't think these groups are as vulnerable
to earnings disappointments as other sectors of the market. Also, we believe
they will be perceived as safe havens and/or bond alternatives for equity
investors seeking a port in what may be a stock market storm.

By the Time They Get to Tucson, We'll be Waiting

In 1992, Tucson Electric Power Company was in bankruptcy. Despite explosive
growth in its market, the company was saddled with uneconomic long-term coal
contracts--all its electric generating plants were coal fired--and local
regulators who would not grant sufficient rate relief to ensure the company's
financial health. The Company was able to re-negotiate contracts with its coal
suppliers at prevailing market prices and emerge from bankruptcy in January,
1998, under a new name, UniSource Energy Corporation.

At year-end 1997, the company's stock was trading at 3.3 times our 1998 cash
flow estimates and 10.7 times our 1998 earnings projections. This compares to
price-to-cash flows in the 5 to 6 range and P/Es in the low to mid teens range
for other electric utilities. Why so cheap? In our opinion, it is the current
lack of a dividend. We believe the company will reinstitute a dividend as early
as second half 1998 and begin attracting traditionally yield-oriented stock
investors. UniSource Energy may attract other investors in the form of larger,
more well-heeled utilities from upstate or over in California with designs on
the fast-growing Tucson market. If the story continues to develop as we think it
will, by the time other investors get to Tucson, we'll be waiting.

"We are not inclined to cancel our life insurance, because we didn't get hit by
 a bus last year."


In full year 1997, the Fund returned 13.7% versus the Russell 2000 Index's 22.4%
advance. In fourth quarter 1997, the Fund declined 8.7% compared to a 3.3% drop
in the Russell 2000 Index. For more information on the Fund, including top ten
holdings, please see the Fund Fact Sheet on page 18.

Mergers and acquisitions were responsible for much of our gains as 10 portfolio
companies were taken over in 1997. We buy stocks based on value, not takeover
prospects. However, we believe strategic corporate buyers are also using value
criteria in assessing potential acquisitions.

The Fund's defensive posture restrained performance. At year-end 1997,
approximately 25% of total assets was allocated to short sales, another 22% was
hedged via S&P 500 short futures, and 8% was held in cash and equivalents. We
actually had nice gains in some of our shorts, most notably Liposome Company,
Inc., Oracle Corporation, and Oxford Health Plans, Inc. Nevertheless, as a
percentage of average 1997 net assets, our short positions resulted in a 2.5%
loss for the year. However, we did successfully short S&P 500 index futures to
hedge the portfolio and produce a positive return for the year. We plan to
remain somewhat defensive in 1998 and are not inclined to cancel our life
insurance, because we didn't get hit by a bus last year.

The Long and the Short of It

To demonstrate our value discipline, we thought it would be interesting to
discuss a long and a short in the same industry. Matrix Pharmaceuticals, Inc. is
a small research and development oriented drug company whose Intradose, a
promising new treatment for shrinking cancerous tumors in the head and neck
region, is now in final clinical trials at the FDA. On the company's
announcements of the withdrawal of one product from

testing and an internal restructuring program, the stock dropped from a 1997
high near $8 per share. Based on most recently stated book values at the end of
the third quarter, Matrix was trading below its stated $3.78 book value and just
above its $2.75 per share in cash. We believe Matrix is a value oriented
opportunity in an industry group that is generally very richly priced.

Compare this with Organogenesis, Inc., a biotech company competing with six
other firms in developing artificial tissue for skin grafts. The company is
losing money, and 1997 revenues are forecast at just $270,000. We estimate book
value at $0.67 per share. Yet, at year-end 1997, the stock was trading at around
40 times book value, with a $484 million market cap. The company submitted its
technology to the FDA for initial testing nearly three years ago. While the
company recently announced that it received premarket approval from the FDA, we
still feel that the stock is overpriced. We are monitoring the situation
carefully and will close our short position if we see evidence Organogenesis can
live up to all the promise baked into its fanciful valuation.

"...we don't think it is an accident that our portfolio performance was enhanced
by takeovers in 1997."


Heartland Value Fund

In 1997, the Fund returned 23.2% versus the Russell 2000 Index's 22.4% advance.
However, in fourth quarter 1997, the Fund declined 5.9% compared to the Russell
2000 Index's decline of 3.3%. For more complete information on the Fund,
including top ten holdings, please refer to the Fund Fact Sheet on page 19.

We are pleased to have materially outperformed the Russell 2000, our benchmark
index for the year. Some of the credit must go to strategic corporate buyers,
who provided new homes for 21 of our portfolio holdings. Strategic corporate
buyers are seeking to extend product lines and distribution systems by acquiring
niche companies in related industries. They appear to be looking for the same
things we are--companies with strong free cash flow, positive earnings dynamics,
capable management and sound balance sheets. Consequently, we don't think it is
an accident that our performance was enhanced by takeovers in 1997.

On an industry group basis, our financial service stocks--brokers, banks and
insurance companies--were among our best performing investments. We have been
reducing the portfolio's exposure to bank stocks, which in our opinion, have
gotten rather richly priced. Our investments in small, specialty retailers hurt
portfolio performance. We must confess to being caught in a "value trap" in this
group. Fundamentally, the stocks looked cheap. But, retailers in general have
struggled this year, especially small, single-category retailers, which have
been hurt worst of all. We have weeded out several losers, but still believe the
sector has merit at current valuations.

Buying the Steak not the Sizzle

Lone Star Steakhouse and Saloon, Inc. stock was sizzling from January 1995 
through April 1996. Then, growth

slowed and momentum investors bailed out, dropping the stock from a high of $45
down to the mid teens. We looked at the menu carefully. It appeared the sizzle
was out of the stock, but that a fundamentally appetizing steak remained. We
began accumulating the stock at $18 per share.

With approximately 265 restaurants, Lone Star is second only to Outback in the
steakhouse category. The balance sheet is squeaky clean, with virtually no debt
and about $150 million in cash. We believe management will use this cash to
renew expansion. Lone Star plans on adding approximately 50 new restaurants and
to broaden its menu in 1998. The company is increasing its advertising budget in
an attempt to revive sales.

At year-end 1997, the stock was trading at around 10.6 times our 1998 earnings
projections and at a relatively modest premium to our estimated $13.91 per share
1997 book value. Insiders own approximately 16% of the stock--with the CEO
personally owning approximately 6% with another 2.5% in stock options at $28 per
share. So, management should be financially motivated to reinvigorate the
company. We expect relatively flat earnings in 1998, but looking farther out, we
believe Lone Star can grow earnings at around 15% annually. If we are right, we
think Lone Star Steakhouse stock will regain some of its sizzle.

VALUE REPORT


Heartland Small Cap Contrarian Fund

With a focus on small company stocks, this Fund seeks maximum long-term growth
through an aggressive value-based strategy. It seeks to take advantage of both
undervalued and overvalued stocks, as well as both rising and declining markets.
The Fund can short stocks it regards as overvalued, use leverage--or borrow--to
enhance returns, and use options and futures to hedge the portfolio. In exchange
for potentially greater returns, these sophisticated techniques involve
additional risks. (Closed to new investors since 11/1/97)

VALUE REPORT


                        Heartland's Risk/Return Spectrum


          [graphic - A spectrum illustrates the potential risk/return of the
          following categories, both the categories and the funds within them
          being listed in an aggregate order of lower to higher potential
          risk/return, respectively: Money Market, which includes the Firstar
          Money Market; Bond, which includes Short Duration High-Yield
          Municipal, U.S. Government Securities and High-Yield Municipal Bond;
          and Equity or Stock, which includes Large Cap Value, Value Plus,
          Mid Cap Value, Value and Small Cap Contrarian.]


In general, with mutual funds, as with other investments, the higher the risk,
the greater the potential return over time. Each investor should choose a fund
with an investment strategy that matches his or her particular investment goals.
Investment return and principal value of an investment will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than their original
cost. There is no assurance that the Firstar Money Market Fund will be able to
maintain a stable net asset value of $1. Firstar Funds are not deposits or
obligations of or guaranteed by Firstar Bank or its affiliates, nor are they
insured by the FDIC, the U.S. Government or any governmental agency. For more
complete information, including charges and expenses, call Heartland Advisors at

                                   Definitions

PLEASE NOTE...

Defined below are the Alpha, Beta and R-Squared measurements presented for our
equity funds. These definitions were provided by Russell Analytics, a division
of the Frank Russell Company, highly regarded specialists in investment
information and statistics. When calculating these measurements for each
Heartland equity fund, we have substituted the Fund's benchmark index for a
"market return" as indicated in the presentation for each fund.

Alpha. A measure of a portfolio's return in excess of the market return, both
adjusted for risk. It is a measure of the manager's contribution to performance
due to security selection. A positive Alpha indicates that the portfolio
outperformed the market on a risk-adjusted basis, and a negative Alpha indicates
the portfolio did worse than the market.

Beta. A measure of the sensitivity of a portfolio's rates of return against
those of the market. A Beta greater than 1.00 indicates volatility greater than
that of the market.

R-Squared. A measure that indicates the extent to which fluctuations in
portfolio returns are correlated with those of the general market. An R-Squared
of .75 indicates that 75% of the fluctuation in a portfolio's return is
explained by the fluctuation of the market.

                        REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------
To the Board of Directors and Shareholders of Heartland Group, Inc.:

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the Heartland Small Cap Contrarian
Fund, Heartland Value Fund, Heartland Mid Cap Value Fund, Heartland Large Cap
Value Fund, Heartland Value Plus Fund and Heartland U.S. Government Securities
Fund (six of the portfolios constituting Heartland Group, Inc., hereafter
referred to as the "Funds") at December 31, 1997, the results of each of their
operations, the changes in each of their net assets and the financial highlights
for the year then ended, in conformity with generally accepted accounting
principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Funds'
management; our responsibility is to express an opinion on these financial
statements based on our audit. We conducted our audit of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit 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 audit, which included
confirmation of securities at December 31, 1997 by correspondence with the
custodian and brokers and application of alternative auditing procedures where
confirmations were not received, provides a reasonable basis for the opinion
expressed above. The financial statements of the Funds presented for the periods
ended on or prior to December 31, 1996 were audited by other independent
accountants whose report dated February 7, 1997 expressed an unqualified opinion
on those statements.

                         NOTES TO FINANCIAL STATEMENTS
                               December 31, 1997
- --------------------------------------------------------------------------------
(1)  Organization

     Heartland Group, Inc. (the "Corporation") is registered as an open-end
     management company under the Investment Company Act of 1940. The Small Cap
     Contrarian Fund, Value Fund, Mid Cap Value Fund, Large Cap Value Fund,
     Value Plus Fund, and U.S. Government Securities Fund (the "Funds"), each of
     which is a diversified fund, are six of the nine series of funds issued by
     the Corporation at December 31, 1997.

(2)  Summary of Significant Accounting Policies

     The following is a summary of significant accounting policies followed
     by the Funds in the preparation of the financial statements:

     (a)  Portfolio securities which are traded on stock exchanges are valued at
          the last sales price as of the close of business on the day the
          securities are being valued, or, lacking any sales, at the latest bid
          price. Each over-the-counter security for which the last sale price on
          the day of valuation is available from NASDAQ and falls within the
          range of the latest bid and asked quotations is valued at that price.
          All other securities traded in the over-the-counter market are valued
          at the most recent bid prices. Foreign securities are valued on the
          basis of quotations from the primary market in which they are traded,
          and are translated from the local currency into U.S. dollars using
          exchange rates as of the close of the New York Stock Exchange. Debt
          securities are stated at fair value as furnished by independent
          pricing services based primarily upon information concerning market
          transactions and dealer quotations for similar securities, or by
          dealers who make markets in such securities. Debt securities having
          maturities of 60 days or less are valued at acquisition cost, plus or
          minus any amortized discount or premium. Securities and other assets
          for which quotations are not readily available are valued at their
          fair value using methods determined by the Board of Directors.

     (b)  The Funds' policy is to comply with the requirements of the Internal
          Revenue Code which are applicable to regulated investment companies
          and to distribute substantially all of their taxable income to their
          shareholders. The Funds accordingly paid no Federal income taxes, and
          no Federal income tax provision is required.

          At December 31, 1997, the U.S. Government Securities Fund had Federal
          income tax capital loss carryforwards of $4,940,986 expiring in 2002,
          $858,458 expiring in 2003, and $358,754 expiring in 2005. The Fund
          does not intend to make distributions of any future realized capital
          gains until its Federal income tax capital loss carryforwards are
          completely utilized. The Mid Cap Value and Large Cap Value Funds
          utilized capital loss carryforwards of $3,604 and $1,071,
          respectively, in 1997.

          Net realized gains or losses may differ for Federal income tax
          purposes primarily as a result of post-October losses which may not be
          recognized for tax purposes until the first day of the following
          fiscal year, wash sales, and the marking-to-market of open futures
          contracts at December 31, 1997.
     
          Statement of Position 93-2 requires that permanent financial reporting
          and tax differences be reclassified to paid in capital. Net assets are
          not affected by these reclassifications.

     (c)  Net investment income, if any, is distributed to each shareholder as a
          dividend. Dividends from the Small Cap Contrarian, Value, Mid Cap
          Value and Large Cap Value Funds are declared and paid annually.
          Dividends from the Value Plus Fund are declared and paid quarterly.
          Dividends from the U.S. Government Securities Fund are declared daily
          and distributed monthly. Dividends are recorded on the ex-dividend
          date. Net realized gains on investments, if any, are distributed
          annually.

     (d)  The Funds record security and shareholder transactions on trade date.
          Net realized gains and losses on investments are computed on the
          identified cost basis. The portion of security gains and losses
          resulting from changes in foreign exchange rates is included with net
          realized and unrealized gains or losses from investments. Dividend
          income is recognized on the ex-dividend date, and interest income is
          recognized on an accrual basis. The Funds amortize premium and accrete
          discount on investments utilizing the effective interest method.

          The Funds are charged for those expenses that are directly
          attributable to them. Expenses that are not directly attributable to
          any one Fund are typically allocated among all Funds issued by the
          Corporation in proportion to their respective net assets, number of
          open shareholder accounts, or net sales, as applicable.

     (e)  Each Fund may enter into futures contracts for hedging purposes, such
          as to protect against anticipated declines in the market value of its
          portfolio securities or to manage exposure to changing interest rates.
          Upon entering into a futures contract, a Fund pledges to the broker
          securities equal to the minimum "initial margin" requirements of the
          exchange. Additionally, the Fund receives from or pays to the broker
          an amount of cash equal to the daily fluctuation in value of the
          contract. Such receipts or payments are known as "variation margin,"
          and are recorded by a Fund as unrealized gains
                                                                              35
<PAGE>
 
          or losses. When the futures contract is closed, a Fund records a
          realized gain or loss equal to the difference between the value of the
          contract at the time it was opened and the value at the time it was
          closed.

          The use of futures contracts involves, to varying degrees, elements of
          market risk in excess of the amount recognized in the Statement of
          Assets and Liabilities. The predominant risk is that the movement of a
          futures contract's price may result in a loss which could render a
          portfolio's hedging strategy unsuccessful.

          The Small Cap Contrarian Fund had the following open short futures
          contracts at December 31, 1997:

          S&P 500            (340)           March 1998       ($3,682,762)
</TABLE> 
     (f)  The Small Cap Contrarian Fund may enter into transactions where it
          will sell a security short (sell a security which the Fund does not
          own for delivery at a future date) and subsequently borrow the same
          security from a broker or other institution to complete the sale. The
          predominant risk is that the market price may increase between the
          date of the short sale and the date on which the Fund must replace the
          borrowed security.

          The Small Cap Contrarian, Value, Mid Cap Value, Large Cap Value and
          Value Plus Funds may each engage in "short sales against the box."
          These transactions involve selling a security that a Fund owns for
          delivery at a specified date in the future. Similarly, each of these
          Funds may also engage in short sales of securities of an issuer
          ("acquiror") that has publicly announced a proposed or pending
          transaction in which a portfolio security of the Fund will be
          converted into securities of the acquiror.

          For financial statement purposes, an amount equal to the settlement
          amount is included in the Statement of Assets and Liabilities as an
          asset and an equivalent liability. The amount of the liability is
          subsequently marked-to-market to reflect the current value of the
          short position. Subsequent fluctuations in the market prices of
          securities sold short, at value, may require purchasing the securities
          at prices which may differ from the market value reflected on the
          Statement of Assets and Liabilities. The Fund is liable for any
          dividends payable on securities while those securities are in a short
          position.

          Each Fund maintains a segregated collateral account with its custodian
          consisting of cash or liquid assets to cover short positions,
          including short sales in acquiror securities. At December 31, 1997,
          the Small Cap Contrarian Fund had cash and liquid assets in the amount
          of $115,994,277 committed as collateral for open short positions. The
          Fund's receivable from securities sold short and deposits with brokers
          for securities sold short are with one major securities dealer. The
          Fund does not require the broker to maintain collateral in support of
          the receivable from securities sold short.

     (g)  A restricted security is a security which has been purchased through a
          private offering and cannot be resold to the general public without
          prior registration under the Securities Act of 1933 (the "Act") or
          pursuant to the resale limitations provided by rule 144 under the Act,
          or an exemption from the registration requirements of the Act. At
          December 31, 1997, the Small Cap Contrarian and Value Plus Funds held
          restricted securities equaling 4.0% and 7.3% of total assets,
          respectively.

          Restricted securities that are eligible for resale to qualified
          institutional buyers pursuant to Rule 144A under the Act, provided
          that such securities have been determined to be liquid pursuant to the
          guidelines adopted by the Board of Directors, are valued at fair value
          as furnished by independent pricing services. All other restricted
          securities are identified below.

     (i)  The preparation of financial statements in conformity with generally
          accepted accounting principles requires management to make estimates
          and assumptions that affect the reported amounts of assets and
          liabilities and disclosure of contingent assets and liabilities at the
          date of the financial statements and the reported amounts of revenues
          and expenses during the reporting period. Actual results could differ
          from those estimates.

(3)  Credit Facility
   
     Firstar Trust Company has made available to the Small Cap Contrarian Fund a
     $25 million credit facility pursuant to a Credit Agreement ("Agreement")
     dated September 5, 1997. The Agreement terminates September 4, 1998.
     Outstanding principal amounts under the credit facility bear interest at a
     rate per annum equal to the prime rate or at the LIBOR rate plus 1.25%.
     Advances are collateralized by securities owned by the Fund and held in its
     custody account pursuant to a Collateral Pledge Arrangement dated September
     5, 1997. During the period September 5, 1997 through December 31, 1997, the
     Fund had an outstanding average daily balance of $1,058,475. The maximum
     amount outstanding during the year ended December 31, 1997 was $17.5
     million. At December 31, 1997, the Fund had no outstanding principal
     amounts under the credit facility. Interest expense amounted to $29,490 for
     the year ended December 31, 1997.

(4)  Investment Management Fees and Transactions with Related Parties
   
     The Funds have management agreements with Heartland Advisors, Inc. (the
     "Advisor") to serve as investment advisor and manager. Under the terms of
     the agreements, the Small Cap Contrarian, Value, Mid Cap Value, and Large
     Cap Value Funds pay the Advisor a monthly management fee at the annual rate
     of .75% of the daily net asset value of the Funds; the Value Plus Fund pays
     the Advisor a monthly management fee at the annual rate of .70% of the
     daily net asset value of the Fund; and the U.S. Government Securities Fund
     pays the Advisor a monthly management fee at the annual rate of .65% of the
     first $100 million of the Fund's average daily net assets, .50% of the next
     $400 million of net assets, and .40% on net assets in excess of $500
     million.
   
     Effective October 1, 1997, the Advisor has voluntarily committed to waive
     the entire management and distribution fees and to reimburse all other
     expenses for the Large Cap Value Fund and to reimburse the Mid Cap Value
     Fund to the extent that annual total fund operating expenses would exceed
     1.25%. The Advisor collected a partial fee for the U.S. Government
     Securities Fund at the annual rate of .50% of the Fund's average daily net
     assets for the period from January 1, 1997 though March 30, 1997 and at the
     annual rate of .25% of the Fund's average daily net assets for the period
     from March 31, 1997 through December 31, 1997. The Advisor may reinstate
     all or a portion of the Funds' fees or discontinue reimbursements at any
     time.
   
     The Funds have adopted a Distribution Plan (the "Plan") pursuant to Rule
     12b-1 under the Investment Company Act of 1940. The Distributor is
     Heartland Advisors, Inc. (the "Distributor"). The Plan requires the Funds
     to pay to the Distributor a quarterly distribution fee on an annual basis
     up to .25% of their daily net

38
<PAGE>
 
     assets. Additionally, for the year ended December 31, 1997, the Distributor
     received for the Value, Value Plus, and U.S.Government Securities Funds
     $10,491, $285 and $3,268, respectively, from investors for commissions for
     Fund shares redeemed and for the Small Cap Contrarian, Value, Mid Cap
     Value, and Value Plus Funds, $48,716, $159,609, $306, and $12,093,
     respectively, for brokerage fees on the execution of purchases and sales of
     portfolio investments.
   
     Officers and certain directors of the Corporation are also officers and/or
     directors of Heartland Advisors, Inc.; however, they receive no
     compensation from the Funds.
   
     As permitted under Rule 10f-3 of the Investment Company Act of 1940, the
     Board of Directors of the Corporation has adopted a plan which will allow
     the Funds, under certain conditions described in the Rule, to acquire 
     newly-issued securities from syndicates in which the Distributor is a
     member.

(5)  Deferred Organization Expenses
   
     For the Small Cap Contrarian, Mid Cap Value, Large Cap Value and Value Plus
     Funds, organization expenses have been deferred and are being amortized on
     a straight-line basis over sixty months. Payments for these expenses were
     advanced by the Advisor, who will be reimbursed by the Funds over the same
     period. The proceeds of any redemption of the initial shares by the
     original shareholders will be reduced by a pro-rata portion of any then
     unamortized expenses. Unamortized deferred organization expenses and the
     related payable to the Advisor at December 31, 1997, were $23,008, $12,321,
     $12,321 and $8,258, respectively. Reimbursement to the Advisor of these
     amounts by the Funds will be subject to any expense limitations and
     reimbursements in effect for the Funds at the time.

VALUE REPORT


Dear Tax-Free Investor

January 2, 1998 marked the first anniversary of the Short Duration High-Yield
Municipal and High-Yield Municipal Bond Funds. We believe both Funds achieved
their stated investment objectives--providing a high level of federally
tax-exempt income.* For the 30 days ending December 31, 1997, the Short Duration
High-Yield Municipal Fund had an SEC yield of 5.6% and the High-Yield Municipal
Bond Fund had an SEC yield of 6.3%.* Short Duration also displayed limited price
volatility--another important objective specific to the Fund.

With interest rates declining along the yield curve, bonds performed better in
1997 than in recent years. In addition, stock market volatility in the fourth
quarter prompted many investors to seek relative safety in the bond market,
sending prices higher and yields lower. We don't know if investors' recent
infatuation with bonds will develop into a more serious romance, but we believe
the fundamental outlook for bonds is very positive at this time. If stocks get
hit hard in 1998 and more investors gravitate to bonds, it should have a
favorable impact on bond pricing.

Regardless of what the stock market does in 1998 and beyond, we believe prudent
investors should have a balanced investment diet with meat (stocks), vegetables
(bonds) and a side of cash. Until quite recently, the majority of investors have
been gorging on stocks and pushing bonds to the side of the plate. This rich
diet could cause a touch of indigestion in the year ahead. Echoing parents
everywhere, we urge investors to Eat Your Vegetables!

As of the end of 1997, the Short Duration High-Yield Municipal Fund had 60% of
net assets in non-rated securities. High-Yield Municipal Bond had 90% in
non-rated bonds. To clear up any misunderstandings investors may have about
non-rated bonds, we want to emphasize that the lack of a rating from the major
credit rating agencies does not necessarily reflect inferior credit quality.
Smaller issues are often non-rated simply because of the costs associated with
receiving a rating. In evaluating non-rated bonds, we do our own intensive
credit analysis and internally assign a rating that we believe accurately
reflects credit quality. Most individual investors don't have the talent or time
to do this and prefer relying on the major credit rating agencies. This is one
of the reasons non-rated bonds generally offer a yield advantage over comparable
credit quality rated bonds.

As many of our shareholders may be aware, for certain investors, a portion of
the Funds' income may be subject to the alternative minimum tax. We are very
sensitive to this issue and have made substantial progress in reducing the
number of securities in the portfolio providing income subject to such
taxation.*

In closing, we are gratified by the Funds' success in their first year of
operations and look forward to continuing to serve our shareholders.

         Sincerely,

"We believe the Fund's focus on essential service issues helped provide high
yields while lowering credit risk."



In fourth quarter 1997, the Fund returned 1.8% compared to the Lehman Brothers
Municipal 1-3 Year Non-Investment Grade Bond Index's 1.4% advance. Since
inception on January 2, 1997, the Fund returned 7.4% compared to a 1997 return
of 7.1% for the Index. For more information on the Fund, please see the Fund
Fact Sheet on page 6.

Before reviewing Short Duration High-Yield's first year of operations, we wanted
to comment briefly on the differences between the Fund and its benchmark index.
The Fund generally holds some cash for liquidity purposes whereas the Index is
always fully invested. At year-end 1997, the Fund had an average portfolio
credit rating of BBB (with 60% in non-rated securities with equivalent credit
ratings assigned by Heartland Advisors). This is somewhat higher than the
Index's maximum credit quality of Ba1. Higher credit quality generally
translates into lower yield. The portfolio may have a longer average maturity
than the Index, giving it a modest yield advantage. All things considered, we
believe these differences will always make our benchmark index a particularly
challenging target.

We believe the Fund's focus on essential service securities (issuers providing a
vital service to a large segment of the public) helped provide high yields while
lowering credit risk. We have included an example of the kind of essential
service bond we favor below. At year-end 1997, hospital, retirement community
and nursing home issues composed nearly 50% of Fund net assets. Electric
utilities, resource recovery and essential service industrial revenue bonds
represented almost 25% and multi-family housing another 15% of Fund net assets.

In the latter part of the year, a few shareholders called to ask why the Fund's
net asset value remained largely unchanged while other bond fund NAVs were
rising as interest rates declined. Low price volatility is part of

our objective. This is a short duration portfolio and therefore, less sensitive
to interest rate swings than a longer term bond fund. Also, the smaller
non-rated issues we favor are generally less interest rate sensitive than
larger, more widely traded issues.

Quality Care

As the name implies, the Alzheimer's Resource Center of Connecticut, a 120-bed
facility located 15 miles southeast of Hartford, is a nursing home specifically
for patients suffering from Alzheimer's Disease. At year-end 1997, the Center
had a 100% occupancy rate and a lengthy waiting list. This unique facility was
financed by the Connecticut Development Authority. The bonds are secured by a
first lien on the net revenues of the facility and by a first mortgage lien on
all property. Additional security is provided by a debt service reserve fund
that was fully funded on June 30, 1997. As of that same date, the bonds had debt
service coverage of 1.2x. The Center is managed by C.A. Moffie, Inc., a firm
with a long and distinguished track record in the long-term care industry. At
year-end 1997, the Connecticut Development Authority bonds for the Alzheimer's
Resource Center of Connecticut produced an attractive yield for a short duration
security that we have assigned a BB+ equivalent credit rating.

"Contrary to the conventional wisdom, the municipal bond market is very
inefficient. Dedicated research can uncover truly special situations."


In fourth quarter 1997, the Fund returned 3.6% compared to the Lehman Brothers
Municipal Non-Investment Grade Bond Index's 3.3% gain. Since inception on
January 2, 1997, the Fund returned 11.7% versus the benchmark index's 1997 10.9%
advance. For more information on the Fund, please see the Fund Fact Sheet on
page 7.

We are pleased to have materially exceeded our benchmark index in the Fund's
first year of operations. We did not accomplish this by making any aggressive
interest rate bets. The Fund's average duration was within a relatively tight
range and finished 1997 at 5.2. We did it by bottoms-up "bond picking". Contrary
to the conventional wisdom, we believe the municipal bond market is very
inefficient. Dedicated research can uncover truly special situations,
particularly in small, less-widely followed non-rated issues. We look at a lot
of these smaller non-rated deals and work extremely hard in our credit analysis
to try to identify solid credits with attractive yields.

As advertised, we have also focused on essential service issuers in regional and
local areas where the demographics should support these services' continued
importance. We have included an example of the kind of essential service bond we
favor below. At the close of the year, nearly 55% of the portfolio's net assets
was in hospital, retirement facility and nursing home credits, another 32% was
in multi-family housing, water and sewer, and resource recovery issues. We
believe our essential service investment themes--the aging of America, the
rebuilding of infrastructure, low cost housing development and resource
recovery--will continue to lead us to attractive, high-yield investment
opportunities.

services located in Mitchell County, Iowa. Mitchell County, Iowa issued a series
of revenue bonds to fund the renovation of MCRHC's hospital and the construction
of new obstetrics and surgical wings and a medical clinic. The Fund owns
$250,000 of the MCRHC 6.35%s due 12/01/14 and $1 million of MCRHC 6.5%s due
12/01/19. Interest and principal payments are secured by the pledge of revenues
from the hospital.

MCRHC is the only hospital in Mitchell County. Since becoming affiliated with
North Iowa Mercy Health Center in Mason City, Iowa in 1994, management's cost
cutting and other initiatives have led to a notable improvement of the
Hospital's financial position. In our opinion, MCRHC is in good shape
financially with no other outstanding debt aside from the $4 million issued. The
hospital and its affiliates have a $1.7 million equity interest in the
renovation/construction project and have established a $180,000 debt service
reserve. When the project is completed, we estimate debt coverage will be in
excess of 2x. While the project is subject to risk, including construction risk
and leverage, we believe this is a solid credit (we have assigned the bonds a
BBB equivalent rating) and a good example of identifying value in a small,
non-rated essential service issue.

                NOTES TO FINANCIAL STATEMENTS o December 31, 1997
- --------------------------------------------------------------------------------
(1)  Organization

     Heartland Group, Inc. (the "Corporation") is registered as an open-end
     management company under the Investment Company Act of 1940. The Short
     Duration High-Yield Municipal Fund and the High-Yield Municipal Bond Fund
     (the "Funds"), each of which is a diversified fund, are two of the nine
     series of funds issued by the Corporation at December 31, 1997.

(2)  Summary of Significant Accounting Policies

     The following is a summary of significant accounting policies followed by
     the Funds in the preparation of the financial statements:

     (a)  Debt securities are stated at fair value as furnished by independent
          pricing services based primarily upon information concerning market
          transactions and dealer quotations for similar securities, or by
          dealers who make markets in such securities. Debt securities having
          maturities of 60 days or less are valued at acquisition cost, plus or
          minus any amortized discount or premium. Securities and other assets
          for which quotations are not readily available are valued at their
          fair value using methods determined by the Board of Directors.

     (b)  The Funds' policy is to comply with the requirements of the Internal
          Revenue Code which are applicable to regulated investment companies
          and to distribute substantially all of their taxable income to their
          shareholders. The Funds accordingly paid no Federal income taxes, and
          no Federal income tax provision is required.

          At December 31, 1997, the Short Duration High-Yield Municipal Fund had
          a Federal income tax capital loss carryforward of $27,690 expiring in
          2005. The Fund does not intend to make distributions of any future
          realized capital gains until its Federal income tax capital loss
          carryforward is completely utilized.

          Net realized gains or losses may differ for Federal income tax
          purposes primarily as a result of post-October losses which may not
          be recognized for tax purposes until the first day of the following
          fiscal year, wash sales, and the marking-to-market of open futures
          contracts at December 31, 1997.

          Statement of Position 93-2 requires that permanent financial reporting
          and tax differences be reclassified to paid in capital. Net assets are
          not affected by these reclassifications.

     (c)  Net investment income is distributed to each shareholder as a
          dividend. Dividends are declared daily and distributed monthly and are
          recorded by the Funds on the ex-dividend date. Net realized gains on
          investments, if any, are distributed annually.

     (d)  The Funds record security and shareholder transactions on trade date.
          Net realized gains and losses on investments are computed on the
          identified cost basis. Interest income is recognized on an accrual
          basis. The Funds amortize premium and accrete original issue discount
          on investments utilizing the effective interest method.

          The Funds are charged for those expenses that are directly
          attributable to them. Expenses that are not directly attributable to
          any one Fund are typically allocated among all Funds issued by the
          Corporation in proportion to their respective net assets, number of
          open shareholder accounts, or net sales, as applicable.

     (e)  The Funds may enter into futures contracts for hedging purposes, such
          as to protect against anticipated declines in the market value of
          their portfolio securities or to manage exposure to changing interest
          rates. Upon entering into a futures contract, a Fund pledges to the
          broker securities equal to the minimum "initial margin" requirements
          of the exchange. Additionally, the Fund receives from or pays to the
          broker an amount of cash equal to the daily fluctuation in value of
          the contract. Such receipts or payments are known as "variation
          margin," and are recorded by the Fund as unrealized gains or losses.
          When the futures contract is closed, the Fund records a realized gain
          or loss equal to the difference between the value of the contract at
          the time it was opened and the value at the time it was closed.

          The use of futures contracts involves, to varying degrees, elements of
          market risk in excess of the amount recognized in the Statements of
          Assets and Liabilities. The predominant risk is that the movement of a
          futures contract's price may result in a loss which could render a
          portfolio's hedging strategy unsuccessful.

          The Funds had the following open short futures contracts at December
          31, 1997:

          Short Duration High-Yield Municipal Fund

                                   Number        Expiration        Unrealized

     (f)  The preparation of financial statements in conformity with generally
          accepted accounting principles requires management to make estimates
          and assumptions that affect the reported amounts of assets and
          liabilities and disclosure of contingent assets and liabilities at the
          date of the financial statements and the reported amounts of revenues
          and expenses during the reporting period. Actual results could differ
          from those estimates.

(3)  Investment Management Fees and Transactions with Related Parties 

     The Funds have management agreements with Heartland Advisors, Inc. (the
     "Advisor") to serve as investment advisor and manager. Under the terms of
     the agreements, the Short Duration High-Yield Municipal Fund pays the
     Advisor a monthly management fee at the annual rate of .40% of the daily
     net asset value of the Fund and the High-Yield Municipal Bond Fund pays the
     Advisor a monthly management fee at the annual rate of .60% of the daily
     net asset value of the Fund.

     The Funds have adopted a Distribution Plan (the "Plan") pursuant to Rule
     12b-1 under the Investment Company Act of 1940. The Distributor is
     Heartland Advisors, Inc. (the "Distributor"). The Plan requires the Funds
     to pay to the Distributor a quarterly distribution fee on an annual basis
     up to .25% of their daily net assets.

     The Advisor has voluntarily committed to waive the entire management and
     Rule 12b-1 fees and to reimburse all other expenses for the Funds for the
     fiscal year ending December 31, 1997. As a result, the Funds did not incur
     any operating expenses for the period ended December 31, 1997. Effective
     January 1, 1998, the Advisor began to reduce the amount of this waiver and
     reimbursement each month by 0.15% on an annualized basis, but will
     voluntarily reimburse the Funds to the extent that annual total fund
     operating expenses would exceed 0.75% for the Short Duration High-Yield
     Municipal Fund and 0.95% for the High-Yield Municipal Bond Fund.

     Officers and certain directors of the Corporation are also officers and/or
     directors of Heartland Advisors, Inc.; however, they receive no
     compensation from the Funds.

     As permitted under Rule 10f-3 of the Investment Company Act of 1940, the
     Board of Directors of the Corporation has adopted a plan which will allow
     the Funds, under certain conditions described in the Rule, to acquire
     newly-issued securities from syndicates in which the Distributor is a
     member. 

(4)  Deferred Organization Expenses

     Organization expenses have been deferred and are being amortized on a
     straight-line basis over sixty months. Payments for these expenses were
     advanced by the Advisor, who will be reimbursed by the Funds over the same
     period. The proceeds of any redemption of the initial shares by the
     original shareholders will be reduced by a pro-rata portion of any then
     unamortized expenses. Unamortized deferred organization expenses and the
     related payable to the Advisor at December 31, 1997, were $18,914 for each
     Fund. Reimbursement to the Advisor of these amounts by the Funds will be
     subject to the expense limitations and reimbursements in effect for the
     Funds at the time. 

(5)  Investment Transactions

     During the period ended December 31, 1997, purchases and sales of
     securities, other than short-term obligations, were as follows (in
     thousands):

                                               Short Duration   High-Yield

                        REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------
To the Board of Directors and Shareholders of Heartland Group, Inc.

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Heartland Short Duration High-Yield
Municipal Fund and Heartland High-Yield Municipal Bond Fund (two of the
portfolios constituting Heartland Group, Inc., hereafter referred to as the
"Funds") at December 31, 1997, the results of each of their operations, the
changes in each of their net assets and the financial highlights for the period
January 2, 1997 (commencement of operations) through December 31, 1997, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Funds' management; our responsibility
is to express an opinion on these financial statements based on our audit. We
conducted our audit of these financial statements in accordance with generally
accepted auditing standards which require that we plan and perform the audit 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
audit, which included confirmation of securities at December 31, 1997 by
correspondence with the custodian and brokers and application of alternative
auditing procedures where confirmations were not received, provides a reasonable
basis for the opinion expressed above.

VALUE REPORT

                             [Photo of Pat Retzer]

Dear Fellow Shareholders

Fourth quarter 1997 was full of surprises, among the most pleasant of which was
a big bond rally. As you know from the introductory letter in the Fund's Third
Quarter Value Report, my longer term outlook for interest rates and bonds was
rather bullish. However, I did not anticipate interest rates plunging the way
they did in the fourth quarter as investors, spooked by a volatile stock market,
flocked into fixed income securities. Can we expect this bond rally to carry
over into 1998? If stock market volatility persists, we may see continued
enthusiasm for bonds and even lower interest rates.

However, I am not a stock market forecaster and don't believe short-term trends
in the equity market should be the primary reason for owning bonds. I believe
income and relative safety of principal are good enough reasons in their own
right to devote a portion of your assets to fixed income securities. If you are
a Wisconsin citizen, I believe you should consider double tax-exempt Wisconsin
municipal securities.

 .    Wisconsin's economy is in excellent shape.

 .    Although the Fund has held over 200 different issues since inception, the
     Fund has never held an issue that has gone into default while in its
     portfolio.*

 .    Your investment goes to finance essential services and other worthwhile
     projects for your State and its communities.

 .    The income from your investment is free from both federal and state income
     taxes.**

We will continue to employ our experience and expertise in the Wisconsin
municipal bond market, and our size advantage over other Wisconsin tax-exempt
funds, to maintain a diversified portfolio of what we view as attractive
municipal issues.

Thank you for your continued support.

                  Sincerely,




                  Patrick J. Retzer, CPA
                  Portfolio Manager

The Value of Double Tax-Free Income


As you can see below, the Heartland Wisconsin Tax Free Fund is designed to
produce income you can keep. And the higher your federal income tax bracket, the
more benefit you realize from double tax-free investing.

VALUE REPORT


                       Heartland Wisconsin Tax Free Fund


In fourth quarter 1997, the Fund returned 2.4% compared to the Lehman 10 Year
Municipal Bond and 20 Year Municipal Bond Indices' 2.6% and 3.4% respective
gains. In full year 1997, the Fund returned 8.1% versus the two benchmark
indices' 9.2% and 10.8% advances. For the year, the Fund's share price rose from
$10.16 to $10.44 while paying dividends of $.52 per share. Dividends were 100%
exempt from both Wisconsin and federal income tax.* For additional information
on the Fund, please see the Fund Fact Sheet on page 4.

Although our long-term outlook for bonds was relatively bullish, concerns about
a very strong economy and rising wage costs led us to shorten the portfolio's
average duration by hedging to protect against the potential for rising interest
rates in the second half of 1997. This restrained returns as long rates plunged
and long bonds soared. We did not foresee two rather extraordinary events: the
problems in Asia, which will very probably take inflationary pressure off the
U.S. economy, and equity investors' renewed enthusiasm for bonds. At year end,
the Fund's weighted average portfolio duration was 9.7 years.

As we have discussed in the past, since the Fund's portfolio consists of only
bonds exempt from federal and Wisconsin income tax, its performance can be
expected to differ from the unmanaged benchmarks, which consist of municipal
bonds from across the country. Given the high demand and limited supply of
double-exempt bonds in Wisconsin, our state's municipal bonds are generally less
sensitive to a volatile interest rate environment than some of the more widely-
held securities in the bench-mark. While this factor may have contributed to our
under-performance in the second half of 1997, in our view, it can also work in
our favor when rising interest rates are on the horizon. In light of the Fund's
Wisconsin double tax-exempt nature, we are pleased with the results we were able
to achieve for our shareholders in 1997.

"Wisconsin municipal bonds are generally not as interest rate sensitive as more
liquid Treasuries."

Bringing Something to the Table

The Community Development Authority of the City of Oconto Falls, Wisconsin,
7.75%s due 12/1/22, are financing a portion of the costs for the acquisition,
construction, and start up of a tissue mill. The mill, which uses 100% recycled
fiber, will produce a unique, high quality product for use in decorative colored
paper napkins and table covers. Management is experienced and financially
committed to the project, with the owner and its members having put up $11.6
million in cash and letters of credit, comprising 31% of the project's cost.
They have a long-term sales contract for 26,000 tons of tissue per year, which
is 100% of the planned initial output. Cash flow from the project is projected
to cover interest expenses at an average rate of 12.2x over the life of the
bonds. While the project is subject to risks, including construction risks and
leverage, in our opinion, this strong projected debt coverage ratio along with
10 years of stable tissue pricing should insulate this project from many risks
on a short-and long-term basis. We feel this is a good example of how we seek to
bring value to the Fund's table and look forward to what we believe will be
decorative returns.


* For 1997, 11.47% of the Fund's income was an item of tax preference for
  purposes of computing the federal alternative minimum tax.

  On December 31, 1997 the Fund's City of Oconto Falls Community Development
  Authority bonds-- 7.75% due 12/1/22-- were valued at $3,030,000 representing
  2.3% of the Fund's net assets.

                        HEARTLAND WISCONSIN TAX FREE FUND
                NOTES TO FINANCIAL STATEMENTS . December 31, 1997
- --------------------------------------------------------------------------------
(1)  Organization

     Heartland Group, Inc. (the "Corporation") is registered as an open-end
     management company under the Investment Company Act of 1940. The Wisconsin
     Tax Free Fund (the "Fund"), which is a non-diversified Fund, is one of the
     nine series of funds issued by the Corporation at December 31, 1997.

(2)  Summary of Significant Accounting Policies

     The following is a summary of significant accounting policies followed by
     the Fund in preparation of the financial statements:

     (a)  Debt securities are stated at fair value as furnished by independent
          pricing services based primarily upon information concerning market
          transactions and dealer quotations for similar securities, or by
          dealers who make markets in such securities. Debt securities having
          maturities of 60 days or less are valued at acquisition cost, plus or
          minus any amortized discount or premium. Securities and other assets
          for which quotations are not readily available are valued at their
          fair value using methods determined by the Board of Directors.

     (b)  The Fund's policy is to comply with the requirements of the Internal
          Revenue Code which are applicable to regulated investment companies
          and to distribute substantially all of its taxable income to its
          shareholders. The Fund accordingly paid no Federal income taxes, and
          no Federal income tax provision is required.

          At December 31, 1997, the Fund had Federal income tax capital loss
          carryforwards of $534,679 expiring in 2003 and $333,310 expiring in
          2005. The Fund does not intend to make a distribution of any future
          realized capital gains until its Federal income tax capital loss
          carryforward is completely utilized.

          Net realized gains or losses may differ for Federal income tax
          purposes primarily as a result of post-October losses which may not be
          recognized for tax purposes until the first day of the following
          fiscal year, wash sales, and the marking-to-market of open futures
          contracts at December 31, 1997.

          Statement of Position 93-2 requires that permanent financial reporting
          and tax differences be reclassified to paid in capital. Net assets are
          not affected by these reclassifications.

     (c)  Net investment income is distributed to each shareholder as a
          dividend. Dividends are declared daily and distributed monthly and are
          recorded by the Fund on the ex-dividend date. Net realized gains on
          investments, if any, are distributed annually.

     (d)  The Fund records security and shareholder transactions on trade date.
          Net realized gains and losses on investments are computed on the
          identified cost basis. Interest income is recognized on an accrual
          basis. The Fund amortizes premium and accretes original issue discount
          on investments utilizing the effective interest method.

          The Fund is charged for those expenses that are directly attributable
          to it. Expenses that are not directly attributable to the Fund are
          typically allocated among all Funds issued by the Corporation in
          proportion to their respective net assets, number of open shareholder
          accounts, or net sales, as applicable.

     (e)  The Fund may enter into futures contracts for hedging purposes, such
          as to protect against anticipated declines in the market value of its
          portfolio securities or to manage exposure to changing interest rates.
          Upon entering into a futures contract, the Fund pledges to the broker
          securities equal to the minimum "initial margin" requirements of the
          exchange. Additionally, the Fund receives from or pays to the broker
          an amount of cash equal to the daily fluctuation in value of the
          contract. Such receipts or payments are known as "variation margin,"
          and are recorded by the Fund as unrealized gains or losses. When the
          futures contract is closed, the Fund records a realized gain or loss
          equal to the difference between the value of the contract at the time
          it was opened and the value at the time it was closed.

          The use of futures contracts involves, to varying degrees, elements of
          market risk in excess of the amount recognized in the Statement of
          Assets and Liabilities. The predominant risk is that the movement of a
          futures contract's price may result in a loss which could render a
          portfolio's hedging strategy unsuccessful.

                                                                              11
<PAGE>
 
          The Fund had the following open short futures contracts at December
          31, 1997:


                                        Number         Expiration    Unrealized
          Type                       of Contracts         Date      Appreciation
          ----                       ------------      ----------   ------------
          U.S. Treasury Bond Index      (200)          March 1998     $ 56,788

     (f)  The Fund has entered into a fee arrangement with its custodian bank
          and transfer agent which provides for a reduction in custody and
          transfer agent fees based upon net amounts of uninvested cash
          balances. This reduction of expenses is shown on the Statement of
          Operations as "Fees Paid Indirectly."

     (g)  The preparation of financial statements in conformity with generally
          accepted accounting principles requires management to make estimates
          and assumptions that affect the reported amounts of assets and
          liabilities and disclosure of contingent assets and liabilities at the
          date of the financial statements and the reported amounts of revenues
          and expenses during the reporting period. Actual results could differ
          from those estimates.

(3)  Investment Management Fees and Transactions with Related Parties

     The Fund has a management agreement with Heartland Advisors, Inc. (the
     "Advisor") to serve as investment advisor and manager. Under the terms of
     the agreement, the Fund pays the Advisor a monthly management fee at the
     annual rate of .65% of the daily net asset value of the Fund.

     Officers and certain directors of the Corporation are also officers and/or
     directors of the Advisor; however, they receive no compensation from the
     Fund.

     As permitted under Rule 10f-3 of the Investment Company Act of 1940, the
     Board of Directors of the Corporation has adopted a plan which will allow
     the Fund, under certain conditions described in the Rule, to acquire
     newly-issued securities from syndicates in which the Advisor is a member.

(4)  Deferred Organization Expenses

     Organization expenses have been deferred and were amortized on a
     straight-line basis over sixty months. Payments for these expenses were
     advanced by the Advisor, who was reimbursed by the Fund over the same
     period. As of December 31, 1997 all organization expenses have been
     amortized.

(5)  Investment Transactions

     During the year ended December 31, 1997, cost of purchases and proceeds
     from sales of securities, other than short-term obligations, were
     $14,705,016 and $9,772,893, respectively.

     At December 31, 1997, the gross unrealized appreciation and depreciation on
     securities for tax purposes were $5,753,072 and $75,368, respectively,
     netting to $5,677,704.

     Cost of investments is substantially the same for financial reporting
     purposes and federal income tax purposes.

                      END OF NOTES TO FINANCIAL STATEMENTS


Effective March 26, 1997, Arthur Andersen LLP was dismissed as the Corporation's
independent accountants. For the years ended December 31, 1993 through December
31, 1996, Arthur Andersen LLP expressed an unqualified opinion on the
Corporation's financial statements. There were no disagreements between the
Corporation's management and Arthur Andersen LLP prior to their dismissal. The
Board of Directors approved the dismissal of Arthur Andersen LLP and the
appointment of Price Waterhouse LLP as the Corporation's independent
accountants.


                        REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------
To the Board of Directors and Shareholders of Heartland Group, Inc.

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the Heartland Wisconsin Tax Free
Fund (one of the portfolios constituting Heartland Group, Inc., hereafter
referred to as the "Fund") at December 31, 1997, the results of its operations,
the changes in its net assets and the financial highlights for the year then
ended, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit 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 audit, which included confirmation of securities at December
31, 1997 by correspondence with the custodian and brokers and application of
alternative auditing procedures where confirmations were not received, provides
a reasonable basis for the opinion expressed above. The financial statements of
the Fund for the four years ended December 31, 1996 were audited by other
independent accountants whose report dated February 7, 1997 expressed an
unqualified opinion on those statements.
