HOW TO USE THIS REPORT
 
For a quick overview of the fund's performance during the past twelve months,
refer to the Highlights box below. The letter from the portfolio manager and
president provides a more detailed analysis of the fund and financial markets.
 
The charts alongside the letter 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 sector or 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

"It was critical I achieve my goals, and I found what I was looking for in the
Fortis U.S. Government Securities Fund. It fit my needs perfectly."
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.
 
During the twelve months ended July 31, 1998, the U.S. economy continued its
brisk pace of growth. Fueled by a rapidly expanding work force, nearly 3 million
more jobs were created and with strong consumer demand, real gross domestic
product, or GDP grew at a 3.5 percent annualized rate.
 
After a scare from the emerging markets in January, it appeared that the
economic problems overseas, Asia in particular, would remain localized, and that
the strong U.S. domestic economy would force the Federal Reserve to raise rates.
As 1998 progressed, however, it became clear that the problems in Asia were more
severe and far reaching than the marketplace originally anticipated. The ripple
effects of Asia began to affect the U.S. economy, negatively impacting GDP.
 
As a result, growth slowed dramatically from the first quarter 1998, 5.5 percent
real GDP in the first quarter 1998, to 1.4 percent real GDP in the second
quarter of 1998. The net result of these events was that interest rates
increased during both February and April, and then declined significantly later
in the second quarter. The 30-year treasury began the year at 5.92 percent,
increased to as high as 6.0 percent, and fell to 5.72 percent on July 31, 1998.
Year to date, long-term rates decreased more than short-term rates. We did not
believe the problems in Asia would remedy quickly, and used the back-up in
interest rates that accompanied the market's premature relief to extend the
portfolio's duration. Currently, the portfolio's duration is 4.75 years.
Duration is a measure of a bond portfolio's sensitivity to changes in interest
rates; therefore a "long duration" portfolio assumes interest rates will
decline.
 
Since callable bonds perform poorly in periods of declining interest rates, we
also improved the overall call protection in the portfolio. This involved
selling conventional mortgage-backed securities, or MBS, which are subject to
immediate prepayment; and buying MBS with better call protection and
non-callable agency debentures. If rates either remain at current levels or
decline further, these securities should provide better total rates of return
than the issues we sold.
 
The fund's return benefitted from our strategies regarding duration, sector
allocation and security selection. Our 12-month total rate of return of 7.42
percent for Class E shares before sales charge compares favorably to the 6.75
percent return for the Morningstar intermediate term govenment bond fund
category average before sales charge and the 6.83 percent for the Lehman
Brothers Intermediate Government Index.
 
Our strategy going forward will depend once again on the severity and duration
of the Asian crisis. Should Asia's problems continue, we anticipate that the
U.S. dollar will remain strong, exports will continue to be restrained, and the
drag on the U.S. economy will prevent the Federal Reserve from having to raise
short-term interest rates. In addition, foreign investors will look to our
markets for "safe-haven investing". These outcomes all suggest interest rates
will likely remain at these levels or move lower.
 
Sincerely,
 
/s/ Dean C. Kopperud                         /s/ Howard G. Hudson

"The Strategic Income Fund gives me an opportunity to diversify my investments.
With its unique investment approach and monthly income, I plan to achieve my
financial goals."
 
YOUR 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.
 
For the U.S. financial markets, in the period since the Strategic Income Fund's
inception on December 1, 1997 through July 31, 1998, domestic economic events
have been overshadowed by a variety of international concerns. These concerns
centered, at least initially, on Southeast Asia and the former Soviet Union. As
time went on, concern spread and worsened to include other "emerging markets"
despite intermittent stopgap efforts of the International Monetary Fund and
other private entities to provide sufficient financing to stop the bleeding.
 
In this environment, the domestic bond market, which was the beneficiary of a
combination of favorable domestic circumstances, continued to be a sympathetic
partner to the equity market in its climb to lofty valuations. These financial
circumstances included a steady monetary policy which featured the right amount
of carefully worded anti-inflationary commentary from the Chairman of the
Federal Reserve, healthy but not excessive growth ( despite quarterly spikes in
activity ), reduced issuance of public sector debt accruing to the balancing of
our federal budget, and the difficulties abroad. As the problems intensified
internationally, the dollar continued to strengthen. This desirable currency
factor, supported by relatively high real rates and the depth, accessibility and
liquidity of U.S. debt markets, created demand for our bonds from foreign
investors. These related factors combined to push our interest rates lower and,
bond prices higher.
 
Given the market environment we diversified the portfolio gradually, weighting
domestic issues more heavily than foreign, establishing small positions in only
a few better quality foreign issues while avoiding most of the more troubled
"emerging markets". Since our fund was initiated at a time of lower interest
rates than most all of our competitors, we found ourselves at somewhat of a
disadvantage but, nonetheless, restrained our investments in the higher yielding
areas. This approach is beginning to bear fruit. The total return of the fund
for the period from December 1, 1997 to July 31, 1998 was 4.77 percent for Class
A shares before sales charge, which compares to 5.20 percent return for the
Lehman Brothers Aggregate Bond Index.
 
Going forward, we will continue to search for opportunities in the foreign
sector which has up to now been underweighted. In the interim, since we believe
the international difficulties to be long-lasting, our domestic high quality
orientation should benefit performance.
 
Sincerely,

YOUR 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.
 
During this twelve-month reporting period, from August 1, 1997 to July 31, 1998,
we've added a new portfolio manager, Ho Wang. Mr. Wang brings to Fortis more
than twenty eight years of experience as a high-yield specialist. He focuses on
investing in high-yield bonds that will maximize the total return for
shareholders. The fund's total return was 4.31 percent for Class A shares before
sales charge for the twelve months ending July 31, 1998, compared to 9.01
percent for the Lehman Brothers High Yield Index.
 
The primary reason this fund underperformed expectations was due to ongoing
problems stemming from two specific holdings in our portfolio, Australis and
Wireless One. The negative earnings situation with these companies began late
last year and continued to deteriorate throughout this reporting period. In
addition, our overweighting in the telecommunications sector hurt performance as
that sector lagged the rest of the market during this period.
 
Our decision to underweight emerging market bonds has significantly helped the
returns for the fund. Specifically, Southeast Asia, Japan and Russia, have
underperformed during 1998.
 
We have refocused our efforts on selecting higher-quality securities for this
portfolio. This strategy is an important element in producing consistant total
rates of return.
 
Looking ahead, we see U.S. economic activity beginning to moderate but we do not
expect this to have a significant influence on the fund. Although we're
currently underweighted in the emerging market sector, we will continue to look
for opportunities within the sector that may add value in the coming months.
 
Sincerely,
 
/s/ Dean C. Kopperud                        /s/ Howard G. Hudson

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) investment and 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 A and E shares are sold with a front-end sales
   charge. For U.S. Government Fund, Class E shares are only available to
   existing shareholders on November 14, 1994. 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 July
   31, 1998, U.S. Government Fund and Strategic Income Fund had entered into
   outstanding when-issued or forward commitments of $4,095,768 and $503,235,
   respectively.
 
   Consistent with its ability to purchase securities on a when-issued basis,
   the U.S. Government Fund and the Strategic Income Fund have entered 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 year ended July 31, 1998, the cost of purchases and proceeds from
   sales of securities (other than short-term securities) were as follows:

</TABLE>
 
   LENDING OF PORTFOLIO SECURITIES: At July 31, 1998, securities valued at
   $159,357,067 were on loan to brokers from U.S. Government. For collateral,
   the Fund's custodian received $164,806,638 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 $154,012 for U.S.
   Government for the year ended July 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.
 
                                                                              25

- --------------------------------------------------------------------------------
 
   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 funds 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 funds 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 funds. 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.
 
   On the Statement of Assets and Liabilities, due to permanent book-to-tax
   differences High Yield's undistributed net investment income has been
   increased $3,247 resulting in reclassifications to paid-in-capital by the
   same amounts.
 
   For federal income tax purposes U.S. Government had a capital loss carryover
   of $65,049,930 and High Yield had $9,435,408 at July 31, 1998, which, if not
   offset by subsequent capital gains, will expire in 1999 through 2007. 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 July 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 June 30, 1998, was $478,125 for Strategic Income and
   $16,235,160 for High Yield which represents 2.05% and 7.26 % 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.
 
   HIGH-YIELD DEBT SECURITIES: Although High Yield and Strategic Income are
   diversified portfolios, the funds have 93.31% and 34.11% of total net assets
   invested in non-investment grade (high-yield) and comparable quality unrated
   high-yield securities, respectively. Participation in high-yielding
   securities transactions generally involves greater returns in the form of
   higher average yields. However, participation in such
   transactions involves greater risks, often related to sensitivity to interest
   rates, economic changes, solvency, and relative liquidity in the secondary
   trading market. Lower ratings may reflect a greater possibility that the
   financial condition of the issuer, or adverse changes in general economic
   conditions, or both, may impair the ability of the issuer to make payments of
   interest and principal. The prices and yields of lower rated securities
   generally fluctuate more than higher quality securities, and such prices may
   decline significantly in periods of general economic difficulty of rising
   interest rates.
 
   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 1.00% 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:

INDEPENDENT AUDITOR'S REPORT
 
The Board of Directors and Shareholders
 
Fortis Income Portfolios, Inc.
Fortis Advantage Portfolios, Inc.:
 
We have audited the accompanying statements of assets and liabilities, including
the schedules of investments in securities, of U.S. Government Securities Fund
and Strategic Income Fund (funds within Fortis Income Portfolios, Inc.) and High
Yield Portfolio (a fund within Fortis Advantage Portfolios, Inc.), as of July
31, 1998 and the related statements of operations, statement of changes in net
assets and the financial highlights for the periods presented. These financial
statements and the financial highlights are the responsibility of fund
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Investment securities held in custody are confirmed to us by the
custodian. As to securities purchased and sold but not received or delivered, we
request confirmations from brokers, and where replies are not received, we carry
out other appropriate auditing procedures. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of U.S.
Government Securities Fund, Strategic Income Fund and High Yield Portfolio as of
July 31, 1998 and the results of their operations, changes in their net assets
and the financial highlights for the periods presented, in conformity with
generally accepted accounting principles.
