HOW TO USE THIS REPORT
 
For a quick overview of the Funds' performance during the past six months, refer
to the Highlights box below. The letters from the portfolio managers and
president provide a more detailed analysis of the Fund and financial markets.
 
The charts following the letters are useful because they provide more
information about your investments. The top holdings chart shows the types of
securities in which the Fund invests, and the pie chart shows a breakdown of the
Fund's assets by industry.
 
The performance chart graphically compares the Fund's total return performance
with a selected investment index. Remember, however, that an index may reflect
the performance of securities the Fund may not hold. Also, the index does not
deduct sales charges, investment advisory fees and other fund expenses, whereas
your fund does. Individuals cannot buy an unmanaged index fund without incurring
some charges and expenses.
 
This report is just one of several tools you can use to learn more about your
investment in the Fortis Family of Mutual Funds. Your investment representative,
who understands your personal financial situation, can best explain the features
of your investment and how it's designed to help you meet your financial goals.

GLOSSARY OF TERMS
Terms defined are in ITALICS in the shareholder letter
 
DURATION: The measure of a bond fund's sensitivity to interest rate changes.
Traditionally measured in years, higher durations mean potentially greater
fluctuations in bond values, just as lower durations typically mean less
volatility.
 
GDP (GROSS DOMESTIC PRODUCT): The market value of a countries total output of
goods and services.
 
YOUR U.S. GOVERNMENT SECURITIES FUND
 
MANAGED WITH A DISCIPLINED, CONSISTENT INVESTMENT APPROACH, THIS FUND IS
DESIGNED TO SEEK A STRONG TOTAL RETURN, AS WELL AS A RELATIVELY HIGH LEVEL OF
CURRENT INCOME, BY FOCUSING ITS INVESTMENTS IN U.S. GOVERNMENT BONDS, TREASURIES
AND MORTGAGE-BACKED SECURITIES.
 
REVIEW
 
In our last shareholder letter, we forecasted that economic growth would pick up
and that the economic expansion would continue well into 1998. We also felt that
the increasingly tight labor market would put pressure on wages and ultimately
result in a modest increase in inflation, prompting the Federal Reserve to raise
short term interest rates. In retrospect, our forecast was right about the
contributing factors. The second half of 1997 did see rapid growth, real GDP was
4.3% in the fourth quarter versus a 3.1% in quarter three. For the entire year,
real GDP was 3.8%, the most rapid gain in almost a decade. Even though the
year-over-year change in average hourly earnings moved up to its current 3.8%
from 3.6% for the July 1997 release (last shareholder letter), these pressures
have not worked their way into the overall inflation rate and the Fed did not
feel compelled to raise short term rates. In addition, the financial crisis in
the Far East resulted in significant inflows into the U.S. Treasury Bond market,
as investors sought a safe-haven for their money. The net result of these events
has resulted in a lower interest rate environment today than the one that
existed six months ago. The ten-year treasury yield has fallen close to 50 basis
points in this time period, with rates now in the 5.5% area versus the 6.0% area
on July 31. The shape of the Treasury yield curve has flattened over the last
six months, as yields on longer maturity Treasuries have fallen more than yields
on shorter maturity Treasuries. For instance, the yield on the two-year Treasury
has fallen by 42 basis points, while 30 year Treasury yields fell by 49 basis
points. The financial crisis in Asia which hit the bond market in October had an
impact on the various other areas of the fixed income market. The flight to
quality generally resulted in all non Treasury areas of the U.S. bond market
underperforming the Treasury market since October.
 
Our strategy over the last six months was similar in many ways to the strategy
that we applied in the prior period. We extended the portfolio's DURATION as
interest rates rose, given our positive long term outlook on rates, and moved
the portfolio's duration to neutral versus our benchmark when rates fell. Once
the crisis in Asia hit, we felt the prudent move was to expose the portfolio to
minimal interest rate risk. Accordingly, we maintained a neutral duration
relationship relative to our benchmark from mid-September to the end of January.
Our duration currently stands at 4.54 years which is virtually unchanged from
the end of July. Currently, 19.8% of our holdings are in agency notes, as we
continue to believe the extra yield these securities offer will enhance total
return. Relative to our benchmark we are underweighted in Mortgage-Backed
Security Pass-Throughs and CMO's as we believe that the better structured agency
and U.S. Treasury securities are a better investment choice as this point in
time. Overall, the Fund produced a return of 4.66% for Class E before sales
charge, compared to the 5.39% return for the Lehman Government Index. The Fund
underperformed the index primarily due to the fact that the Fund generally
invests in more conservative securities than those contained in the index. The
Fund's performance does however compare favorably to the 4.39% return for the
Morningstar universe of U.S. Intermediate Government Bond funds.
 
OUTLOOK
 
Our strategy going forward will depend upon the severity and duration of the
Asian crisis. Specifically, should the difficulties in the Far East continue as
anticipated, it is likely that the spillover will slow U.S. economic growth, due
to a deterioration in net exports. In addition, a continuation of the crisis
should perpetuate the strength of the U.S. Dollar, making foreign goods cheaper
and decreasing the risks of inflation. If this scenario plays out, rates most
likely will move lower, possibly much lower and mortgage-backed securities would
see a large jump in prepayments thus hurting returns in this sector. If the
situation in the Far East is resolved quickly, the current

reinvestment of all dividend and capital gains distributions. The performance of
the separate classes (E, A, B, C, and H) will vary based on the differences in
sales loads and distribution fees paid by shareholders investing in the
different classes. Class E and A have a maximum sales charge of 4.50%, Class B
and H have a CDSC of 4.00% if redeemed within two years of purchase, or 3.00% if
redeemed in year three or four (with a waiver of 10% of the amount invested).

With its unique investment approach and monthly income, I plan to achieve my
financial goals."
 
YOUR FORTIS STRATEGIC INCOME FUND
 
THE FUND'S INVESTMENT OBJECTIVE IS TO MAXIMIZE TOTAL RETURN (FROM CURRENT INCOME
AND CAPITAL APPRECIATION) BY PRIMARILY INVESTING IN A DIVERSIFIED PORTFOLIO OF
U.S. GOVERNMENT SECURITIES, INVESTMENT AND NON-INVESTMENT GRADE BONDS ISSUED BY
FOREIGN GOVERNMENTS AND COMPANIES, AND NON-INVESTMENT GRADE BONDS ISSUED BY U.S.
COMPANIES.
 
REVIEW
 
The Strategic Income Fund commenced operations on December 1, 1997 amidst
turbulent international cross-currents. The currency and banking crisis that
began during the summer in Thailand spread throughout Asia by year end. In
general, fixed income markets in less-developed economies, like Russia and
Brazil, were all negatively affected. Many of these bond markets had been among
the outstanding total return performers for the last two years. As the crisis
worsened in late December and early January, investors continued to flee for the
safe haven of U.S. Treasuries and the U.S. dollar, which pushed up the values
for these assets.
 
Our initial posture was to minimize the Fund's exposure to the Asian chaos and,
consequently, over 77% of the Fund was invested in U.S.-related securities by
January 31st. Of the 22% exposure to foreign bonds, 19% of the portfolio was
invested in investment-grade issuers, like the Province of Quebec and the Bank
of Austria. Our holdings in the more aggressive foreign markets were limited to
government bonds issued by Mexico. Our lower-rated, U.S. high yield exposure was
approximately 27% as of January 31st. All of our investments in the Fund were
dollar-denominated. The Fund returned 2.89% for Class A before sales charge,
from December 1, 1997 to January 31, 1998. The Lehman Aggregate Bond Index
returned 2.29% during this same time period. The Fund's outperformance of the
index was due mainly to the performance of the Fund's high yield holdings.
 
OUTLOOK
 
Going forward, we believe that a slowdown in the global economy precipitated by
the Asian crisis should mute inflationary pressures, which should generally
prove beneficial for bonds. We also believe that some of our best opportunities
in the future may lie within the Pacific Rim markets or other less-developed
foreign markets that have been unfairly tarnished by the recent world-wide
volatility.
 
Sincerely,

"It makes sense to put part of my money into the High Yield Portfolio. I want
the opportunity to earn the kind of returns that high yield bonds can offer."
 
YOUR FORTIS HIGH YIELD PORTFOLIO
 
LONG-TERM INVESTORS, WILLING TO ACCEPT GREATER PRICE FLUCTUATIONS, MAY CHOOSE TO
DIVERSIFY THEIR STOCK OR BOND INVESTMENTS WITH THIS PORTFOLIO OF HIGHER YIELDING
BONDS. ITS MONEY MANAGERS INVEST IN A WIDELY DIVERSIFIED PORTFOLIO OF
LOWER-RATED CORPORATE BONDS.
 
REVIEW
 
Buoyed by the strength of the global economy, low default rates, low inflation
and robust U.S. stock and Treasury bond markets, high yield securities, on
average, recorded their third straight year of double-digit returns in the
period ended January 31, 1998.
 
The High Yield Portfolio recorded a disappointing 3.66 percent return for Class
A before sales charge for the semi-annual period. Although the Portfolio
generated well above-average income, it fell short of its goal of delivering
above-average total returns (income plus change in market value) versus its
competitive universe. Most of the shortfall in the 1997's performance can be
attributed to specific bond holdings, rather than industry sector or quality
weightings.
 
Australis Media, an Australian pay-television operator, had its bonds drop
substantially in price after a failed merger. The bonds of Wireless One, a U.S.
wireless cable television company, declined throughout the year as concerns
increased that the company had insufficient cash to continue the construction of
its cable systems. From an industry sector standpoint, our focus on
telecommunication companies and traditional cable television companies helped
the Portfolio's performance. Also beneficial was our avoidance of supermarket
bonds, and generally, bonds issued by companies sensitive to the business cycle,
like steel, chemical and forest products concerns.
 
OUTLOOK
 
Our 1998 outlook for high yield bonds is positive, but cautious. The
near-collapse of the Asian economies may slow the U.S. economy in 1998 and
thereby increase the risk of default among lower-rated issuers of corporate
debt. Although demand for high yielding, lower-rated paper is at all-time highs,
the difference ("spread") between these securities and U.S. government bonds is
historically narrow. In addition, the U.S. stock market, often the primary
source for companies looking to reduce their debt burden, has had an
unprecedented three-year upswing, which may prove hard to match in 1998. Our
current strategy is to work to improve the overall credit quality of the
portfolio. While this may result in lower dividends at some point in the year,
our efforts will be focused on improving the total return of the portfolio.
 
Sincerely,

FORTIS BOND FUND
 
Notes to Financial Statements
 
- --------------------------------------------------------------------------------
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: The funds are open-end,
   diversified management investment companies, each of which has different
   investment objectives and their own investment portfolios and net asset
   values. U.S. Government Securities Fund ("U.S. Government") and Strategic
   Income Fund are series of Fortis Income Portfolios, Inc. ("Fortis Income")
   and Fortis High Yield Portfolio ("High Yield") is an investment portfolio in
   Fortis Advantage Portfolios, Inc. ("Fortis Advantage"). The investment
   objectives of each portfolio are as follows:
 
   - The objective of the U.S. Government Securities Fund is to maximize total
     return (from current income and capital appreciation), while providing
     shareholders with a level of current income consistent with prudent
     investment risk.
 
   - The objective of the Strategic Income Fund is to maximize total return
     (from current income and capital appreciation) by primarily investing in
     (a) U.S. Government securities, (b) investment and non-investment grade
     fixed income securities issued by foreign governments and companies, and
     (c) non-investment grade fixed income securities issued by U.S. issuers,
     which, in the opinion of the portfolio's investment adviser, do not subject
     the fund to unreasonable investment risk.
 
   - The objective of the Fortis High Yield Portfolio is to maximize total
     return (from current income and capital appreciation) with a focus on high
     current income by investing primarily in a diversified portfolio of high
     yielding, fixed income securities which, in the opinion of the portfolio's
     investment adviser, do not subject the portfolio to unreasonable investment
     risk.
 
   The Articles of Incorporation of Fortis Income and Fortis Advantage permit
   the Board of Directors to create additional portfolios in the future.
 
   The funds offer Class A, Class B, Class C, Class E (for U.S. Government only)
   and Class H shares.
 
   The U.S. Government Fund and Fortis High Yield Portfolio began to issue
   multiple class shares effective November 14, 1994. The inception of Strategic
   Income Fund was November 10, 1997, and the commencement of operations was
   December 1, 1997. Class E shares are only available to existing shareholders
   on November 14, 1994. Class A and E shares are sold with a front-end sales
   charge. Class B and H shares are sold without a front-end sales charge and
   may be subject to a contingent deferred sales charge for six years, and such
   shares automatically convert to Class A after eight years. Class C shares are
   sold without a front-end sales charge and may be subject to a contingent
   deferred sales charge for one year. All classes of shares have identical
   voting, dividend, liquidation and other rights and the same terms and
   conditions, except that the level of distribution fees charged differs
   between classes. Income, expenses (other than expenses incurred under each
   class's distribution agreement) and realized and unrealized gains or losses
   on investments are allocated to each class of shares based on its relative
   net assets.
 
   The significant accounting policies followed by the Funds are summarized as
   follows:
 
   SECURITY VALUATION: Investments in securities traded on a national securities
   exchange or on the NASDAQ National Market System are valued at the last
   reported sales price. Securities for which over-the-counter market quotations
   are readily available are valued on the basis of the last current bid price.
   An outside pricing service may be utilized to provide such valuations. For
   fixed income securities, the pricing service may employ electronic data
   processing techniques and/or a matrix system to determine valuations using
   methods which include consideration of yields or prices of bonds of
   comparable quality, type of issue, coupon, maturity and rating indications as
   to value from dealers, and general market conditions. Securities for which
   quotations are not readily available are valued at fair value as determined
   in good faith by management under supervision of the Board of Directors.
   Short-term investments, with maturities of less than 60 days when acquired,
   or which subsequently are within 60 days of maturity, are valued at amortized
   cost.
 
   SECURITIES PURCHASED ON A WHEN-ISSUED BASIS: Delivery and payment for
   securities that have been purchased by the funds on a forward commitment or
   when-issued basis can take place a month or more after the transaction date.
   During this period, such securities are subject to market fluctuation and the
   portfolio maintains, in a segregated account with its custodian, assets with
   a market value equal to the amount of its purchase commitments. As of January
   31, 1998, U.S. Government Fund and Strategic Income Fund had entered into
   outstanding when-issued or forward commitments of $49,615,962 and $752,976,
   respectively.
 
   Consistent with its ability to purchase securities on a when-issued basis,
   the U.S. Government Fund and the Strategic Income Fund may enter into
   transactions to defer settlement of its purchase commitments. As an
   inducement to defer settlement, the portfolio repurchases a similar security
   for settlement at a later date at a lower purchase price relative to the
   current market. This transaction is referred to as a "dollar roll".
 
   SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME: Security transactions
   are accounted for on the trade date. Interest income is recorded on the
   accrual basis. Realized security gains and losses are determined using the
   identified cost method. Each fund amortizes original issue discount, long
   term bond premium, and market discount.
 
   For the period ended January 31, 1998, the cost of purchases and proceeds
   from sales of securities (other than short-term securities) were as follows:

Fortis High Yield Portfolio..................      283,543,064       269,420,589
</TABLE>
 
   LENDING OF PORTFOLIO SECURITIES: At January 31, 1998, securities valued at
   $160,601,078 were on loan to brokers from U.S. Government. For collateral,
   the Fund's custodian received $164,483,619 in cash which is maintained in a
   separate account and invested by the custodian in short term investment
   vehicles. Fee income from securities lending amounted to $87,195 for U.S.
   Government for the period ended January 31, 1998. The risks to the funds in
   security lending transactions are that the borrower may not provide
   additional collateral when required or return the securities when due and
   that the proceeds from the sale of investments made with cash collateral
   received will be less than amounts required to be returned to the borrowers.

- --------------------------------------------------------------------------------
 
   DEFERRED COSTS: Registration costs are deferred and charged to income over
   the registration period. Organizational costs were incurred with the
   commencement of operations of the Strategic Income Fund. These costs will be
   amortized over 60 months on a straight line basis, beginning December 1,
   1997.
 
   FEDERAL TAXES: The Portfolios intend to qualify, under the Internal Revenue
   Code, as regulated investment companies and if so qualified, will not have to
   pay federal income taxes to the extent their taxable net income is
   distributed. On a calendar year basis, the Portfolios intend to distribute
   substantially all of their net investment income and realized gains, if any,
   to avoid the payment of federal excise taxes.
 
   Net investment income and net realized gains may differ for financial
   statement and tax purposes. The character of distributions made during the
   year from net investment income or net realized gains may, therefore, differ
   from their ultimate characterization for federal income tax purposes. Also,
   due to the timing of dividend distributions, the fiscal year in which amounts
   are distributed may differ from the year that the income or realized gains
   (losses) were recorded by the Portfolios. The effect on dividend
   distributions of certain current year permanent book-to-tax differences is
   reflected as excess distributions of net realized gains in the statements of
   changes in net assets and the financial highlights.
 
   For federal income tax purposes U.S. Government had a capital loss carryover
   of $72,061,071 and High Yield had $12,157,664 at July 31, 1997, which, if not
   offset by subsequent capital gains, will expire in 1998 through 2006. It is
   unlikely the Board of Directors will authorize a distribution of any net
   realized gains until the available capital loss carryover has been offset or
   expired.
 
   INCOME AND CAPITAL GAINS DISTRIBUTIONS: Distributions from net investment
   income are declared daily and paid monthly. The funds will generally make
   annual distributions of any realized capital gains as required by law. These
   income and capital gains distributions may be reinvested in additional shares
   of the fund at net asset value without any charge to the shareholder or
   payable in cash.
 
   ILLIQUID SECURITIES: At January 31, 1998, investments in securities for the
   Strategic Income Fund and High Yield Portfolio included issues that are
   illiquid. The funds currently limit investments in illiquid securities to 15%
   of net assets, at market value, at the date of purchase. The aggregate value
   of such securities at January 31, 1998, was $1,041,874 for Strategic Income
   and $15,215,684 for High Yield which represents 4.95% and 6.74 % of net
   assets respectively. Pursuant to guidelines adopted by the Board of
   Directors, certain unregistered securities are determined to be liquid and
   are not included within the 15% limitation specified above.
 
   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 of assets and
   liabilities and disclosure of contingent assets and liabilities at the date
   of the financial statements and the reported amounts of increase and decrease
   in net assets from operations during the reporting period. Actual results
   could differ from those estimates.
 
2. PAYMENTS TO RELATED PARTIES: Fortis Advisers, Inc., is the investment adviser
   for the fund. Investment advisory and management fees are computed at an
   annual rate of .8% of the first $50 million of average daily net assets and
   .7% of net assets in excess of $50 million for U.S. Government, Strategic
   Income, and High Yield. In addition to the investment advisory and management
   fee, Classes A, B, C and H pay Fortis Investors, Inc., (the principal
   underwriter) distribution fees equal to .25% of average daily net assets for
   Class A for U.S. Government and Strategic Income and .35% of average daily
   net assets for Class A of High Yield and U.S. Government, Strategic Income,
   and High Yield (Class B, C and H) of average daily net assets (of the
   respective classes) on an annual basis, to be used to compensate those who
   sell shares of the fund and to pay certain other expenses of selling fund
   shares. Fortis Investors, Inc., also received sales charges (paid by
   purchasers or redeemers of the fund's shares) as follows:

   Advisers has voluntarily undertaken to limit annual expenses for Strategic
   Income (exclusive of interest, taxes, brokerage commissions and non-recurring
   extraordinary charges and expenses) commencing December 1, 1997 to 1.10% of
   daily net assets. During the semi-annual period ended January 31, 1998,
   Advisers waived $5,340 of its advisory fee.
 
   For the period ended January 31, 1998, legal fees and expenses were paid to a
   law firm of which the secretary of the fund is a partner.
