               John Cleland

TO OUR SHAREHOLDERS:

The six month period ended June 30, 2000 was characterized by enormous interest
rate volatility which we believe is likely to continue as momentum investors
move large amounts of money into and out of fixed income asset classes and
maturity ranges. The volatility was heightened by an unusual element during the
period, the Treasury Department's announcement and implementation of a buy-back
program for long-term Treasury debt.

THE TREASURY DEPARTMENT BUYS BACK HIGH-INTEREST DEBT SECURITIES

Under the buy-back program the Treasury Department is purchasing outstanding
long-maturity government bonds in an effort to reduce the government's interest
expense burden. This program was made possible by the current budget surplus
which was a result of the country's strong economic growth. Treasury
Department's repurchase activity drove down interest rates on long-term
government securities as demand increased in the face of diminishing supply.
This decrease in long-term rates, coupled with the continued increases in
short-term interest rates put in place by the Federal Reserve Bank, resulted in
an inversion of the yield curve, increasing volatility in the markets.

THE FED MAY TAKE A "WAIT AND SEE" STANCE

After six successive rate increases by the Federal Reserve Bank's policy-making
Open Market Committee over the past year, the Committee's decision to leave
rates unchanged at their June 27 and 28, 2000 meeting acknowledged the
unmistakable signs of an economic slowdown. While the Federal Reserve is never
absent from the investment scene, we believe the possibility now exists that
they will make no further rate changes through the remainder of this year,
particularly in view of the upcoming election cycle. Instead, they could choose
to wait and see if evidence of an economic slowdown becomes more convincing.

If in fact the slowdown continues, it should offer bond investors the
opportunity to benefit from a corresponding decline in interest rates. We
believe fixed income investors may have an opportunity to generate superior
investment returns over the year as a whole for the first time in many years.

CONSOLIDATION OF FIXED INCOME PORTFOLIOS

Effective May 1, we merged the U.S. Government Series, the Limited Maturity
Series, and the Corporate Bond Series into one portfolio named the Diversified
Income Series. We believe this will offer investors the benefits of cost
effectiveness and a better diversified fixed income portfolio.

On the following pages our fixed income portfolio managers discuss their
portfolios' performances and the outlook for the months ahead. As always, we
welcome your questions and comments at any time.

Sincerely,

/s/ John Cleland

            MANAGER'S COMMENTARY

            SECURITY MUNICIPAL BOND FUND

            JUNE 30, 2000

[AMODEO PHOTO]
               Robert Amodeo

TO OUR SHAREHOLDERS:

Security Municipal Bond Fund benefited from a rally in the municipal bond market
in the first half of this year. The Fund generated a total return of +4.50% over
the six months, comparing favorably with the +4.48% return of the benchmark
Lehman Brothers Municipal Bond Index.(1) The Fund also handily outperformed the
+3.95% average return of its Lipper peer group of funds.

HIGHLIGHTS OF THE MUNICIPAL MARKET IN THE FIRST HALF

An uneventful transition into the year 2000 despite the "Y2K" fears that
prevailed late last year, accompanied by strong demand for tax exempt
securities, helped municipal bonds post positive price returns during the first
half of this year. Performance was especially robust during the first three
months, outpacing most other fixed income asset classes. During April and May,
however, municipals experienced some difficulty but turned around yet again to
close the half on a positive note in June.

A significant decline in municipal new issue supply helped maintain the positive
tone in the markets. Overall, $92 billion of new municipal supply came to the
market, representing a 22% decline versus the similar period last year. The drop
in municipal supply was due primarily to a lack of refunding activity (refunding
refers to replacing existing bond issues through the sale of new bond issues,
usually to lower the interest rate being paid). In this year's higher interest
rate environment it was difficult for issuers of municipal debt to achieve a
present value cost savings great enough to warrant replacing existing debt with
new debt. At the end of June, refunding activity was down 69% year to date from
the same period a year ago, while funding for new projects was relatively
unchanged. We estimate that $175 billion in municipal debt will be issued during
this year overall.

CHARACTERISTICS OF THE PORTFOLIO

Our philosophy of focusing on long-term fundamentals, rigorous credit analysis
and sector selection remains the foundation for managing the Municipal Bond
Fund. At the end of June the portfolio consisted of twenty-nine issues in
thirteen different states. It had an average maturity of sixteen years, with a
duration of about 8.5 years. The portfolio's overall average credit quality
remains at a strong AA rating. Sector weightings are well-balanced with the
greatest emphasis in general obligation, water and sewer, and transportation
bonds.

OUR MARKET OUTLOOK

We expect the domestic economy to pull back from its torrid pace of growth seen
in the first half of the year. However, we remain concerned about inflation
levels and rising commodity prices. While some recent economic data indicate a
moderating economy, we also note that inflation is not declining as quickly as
the economic data.

Overall, we believe the U.S. economy will remain stable this year as low
unemployment and strong consumer confidence will likely support demand for
goods. Furthermore, we believe the Federal Reserve Bank will engineer a good
balance between strong economic growth and an acceptable rate of inflation.

Sincerely,

Robert Amodeo, Portfolio Manager

            MANAGER'S COMMENTARY

            SECURITY INCOME FUND DIVERSIFIED INCOME SERIES

            JUNE 30, 2000

   Steven M. Bowser                                      Christopher L. Phalen

TO OUR SHAREHOLDERS:

The new Diversified Income Series of Security Income Fund appears for the first
time in this report, the result of the merger of the Corporate Bond Series, U.S.
Government Series, and Limited Maturity Series portfolios. The Diversified
Income Series gained 2.75% over the six month period ended June 30, 2000.(1) The
benchmark Lehman Brothers U.S. Aggregate Bond Index gained 3.99% over the same
period.

AN UNUSUAL TREASURY BOND MARKET

Price movement this year in the longer maturities of the Treasury bond market
this year was governed by an unusual factor. On January 13 the Department of the
Treasury formally announced its plan to repurchase outstanding U.S. Treasury
securities, saying it would buy back as much as $30 billion of these securities
during the year 2000. The buybacks during the first half of this year focused
primarily on the longer maturity issues bearing high interest rates. Through
this process the Treasury Department plans to substantially reduce the Federal
government's annual interest expenses.

The result for fixed income markets was an outsized gain in the price of
long-maturity Treasury bonds while corporate bonds, which didn't benefit from
the "buyback" effect, have lagged in total return. Steps taken by the Federal
Reserve Bank to increase interest rates pushed up yields on most fixed
instruments, but Treasury issues subject to the buyback process escaped most of
this impact.

RESULTS OF MERGER AND STRUCTURE OF THE COMBINED PORTFOLIO

In the process of merging the three portfolios a number of investment grade and
high yield bonds were sold. While some losses were incurred in these sales, we
completed the restructuring with a portfolio which we believe will be a solid
performer during the second half of the year.

At the close of June the Diversified Income Series was comprised of 35%
mortgage-backed securities, 27% Federal agency issues, 16% investment grade and
Yankee corporate bonds, 17% U.S. Treasury securities, and 5% high yield
corporate bonds. We plan to bring this mixture more closely in line with that of
the benchmark index over the coming months. At this time the Lehman Aggregate
Bond Index consists of 23% investment grade corporates, 30% Treasuries, 10%
Federal agencies, and 37% mortgage-backed issues.

The focus in the corporate bond portion of the portfolio will continue to be on
quality investment-grade companies with maturities primarily in the ten year or
lower range. We will use Treasury and Federal agency securities to fill in the
longer part of the maturity range, since these issues are less subject to event
risk that sometimes occurs with an issue in the corporate market spectrum.

HIGH YIELD BONDS WERE WEAK IN THE FIRST HALF

Prior to the merger, the high yield bond portions of the various portfolios
reduced overall return. High yield bonds tend to follow price movements in the
stock markets as well as in the bond markets, and many stock indexes were
negative in the first half of the year. In January, high yield issues made up
about 14% of assets in the former Corporate Bond Series and about 20% of the old
Limited Maturity Series. Because of their continuing underperformance, we
reduced the high yield position in the newly combined Series to its current 5%
weighting and plan to keep it generally between 5% and 10% of assets.

OUTLOOK FOR FIXED INCOME MARKETS

We believe the Federal Reserve Bank is near the end of its cycle of interest
rate increases. Once the economy exhibits solid evidence of slowing, as the Fed
intends, bonds should enjoy a period of price recovery. Because corporate,
mortgage-backed, and Federal agency securities

have suffered more than Treasuries so far this year, when the recovery is
underway, they should outperform during the upward price moves. Interest rate
spreads on these categories of bonds currently stand at historically wide levels
over comparable-maturity Treasury bonds. These spreads are expected to narrow
sharply when bond prices begin to recover.

            SECURITY INCOME FUND HIGH YIELD SERIES

            JUNE 30, 2000

[TOUSSAINT PHOTO]
            David G. Toussaint

TO OUR SHAREHOLDERS:

The High Yield Series of Security Income Fund generated a total return of -1.99%
during the first half of this year, compared to the -1.21% produced by the
benchmark Lehman Brothers Corporate High Yield Index.(1) As you know, high yield
bonds often track the stock markets more closely than the bond markets. In the
six months just completed, many stock market indexes produced negative results
as well.

A RECAP OF THE FIRST HALF

The high yield bond markets in general declined through most of the first five
months of 2000. June brought a reversal, with bond prices rising as investors
perceived that the Federal Reserve Bank was at or near the end of its cycle of
raising interest rates. After several months of outflows of cash from high yield
mutual funds, money started returning to these funds when yields became more
attractive on a historic basis.

When investor interest was rekindled and cash flows increased late in the first
half, many corporate treasurers moved quickly to the high yield markets with
offerings of new bond issues. These new issues were mostly from higher quality,
more established high yield companies and were very well received by investors.
This increase in supply, however, may dampen investors' enthusiasm in the coming
months if it keeps bond prices from improving as much as they would have in its
absence.

DEFAULT RATES HAVE RISEN

Throughout 1997 and 1998 high yield bond issuance was heavy, meeting the demands
of investors looking for yield. We now are seeing the darker side of this
abundant new issuance, with default rates among high yield companies rising in
recent months. Nursing home operators Genesis Health Ventures Inc. and Multicare
Companies Inc. both announced that they would be unable to meet regular coupon
interest payments that came due in March and April. Both companies were hurt by
federal legislation which cut their Medicare reimbursement payments.

Oakwood Homes Corporation, a producer of manufactured homes, reported a greater
than expected quarterly loss and a sharp decline in sales. Their increasing lack
of financial flexibility led to a downgrade in the company's securities.
American Eco Corporation, which outsources services to the energy and power
generation industries, said in its quarterly report released in April that it
was not in compliance with some of its credit covenants.

STRONG PERFORMANCE FROM ENERGY, GAMING, AND TECHNOLOGY

But there is much good news among our portfolio holdings as well. Energy-related
companies saw their bond prices rise substantially as the price of crude oil
climbed from $21 at the beginning of the year to $32 at the end of the first
half. Among these companies, we own securities issued by Ocean Energy
Corporation, Crown Central Petroleum Corporation, and Giant Industries, Inc.

In the leisure sector many gaming companies benefited from increased cash flows
attributed to the strong economy. We concentrated on the higher quality BB-rated
issues, and saw nice price gains in many of these names. Included in this group
are bonds issued by MGM Grand, Inc., Harrah's Entertainment, Inc., Park Place
Entertainment Corporation (which operates under the brand names Bally's,
Caesars, Flamingo, Grand, and Hilton), and Isle of Capri Casinos, Inc.

The third group which proved beneficial in the first half is technology. Amkor
Technology, Inc., provides semiconductor packaging and test services. Orius
Corporation operates in the telecommunications service arena, laying

cable and installing premise wiring as well as providing outsourcing services.

HIGH YIELD MARKETS APPEAR TO HAVE STABILIZED

Our cash positions have been a bit higher than usual throughout the first half
of the year, reflecting our caution about investing in a somewhat shaky market.
In recent weeks, however, the high yield markets seem to be more stable,
particularly following the positive movements in the stock markets. We plan to
put the cash to work as appropriate opportunities arise, concentrating on BB
rated credits and better single-B rated names. We believe the Federal Reserve
Bank is near the conclusion of its cycle of interest rate increases, and high
yield bonds should perform well when interest rates begin declining.

            JUNE 30, 2000

TO OUR SHAREHOLDERS:

During the first half of this year, as in the second half of 1999, money market
funds were the only fixed income sector to benefit from the Federal Reserve
Bank's series of interest rate increases. Higher interest rates increased the
return of the Fund without damaging your invested principal. The seven-day
annualized yield of the Fund at June 30 was 5.73%, up from 5.28% at the close of
last year. The total return for the six month period ended June 30, 2000 was
2.59%, close to the 2.66% average of its Lipper peer group of funds.(1)

increases in its target interest rates, it is referring to the Federal funds
rate, which is the rate at which banks lend money to each other on an overnight
basis. The FOMC often increases its discount rate as well; this is the rate at
which the Federal Reserve Bank lends funds to member banks. Both of these rates
are short term; consequently, the impact on money market instruments is
immediate. In fact, many times investors in money market instruments anticipate
the likelihood that the FOMC will increase rates and force up the rates on money
market instruments ahead of the actual announcement.

CHARACTERISTICS OF PORTFOLIO ASSETS

In periods when interest rates are rising, we believe it is prudent to keep the
average maturity of the securities in the portfolio shorter than usual in order
to more quickly take advantage of higher rates. The average maturity of the
holdings in Security Cash Fund at June 30, 2000 was 39.5 days, compared with the
52 day average maturity of the benchmark Money Fund Report.

The portfolio is currently made up of 53.5% commercial paper, 19.4% Federal
agency discount notes and securities, 4.9% SBA issues, 1.7% floating rate
government securities, 8.4% funding agreements, and 12.1% Sallie Mae floating
rate issues. A broadly diversified portfolio such as this gives us more
flexibility to adjust in a rising interest rate environment.

OUTLOOK FOR THE SECOND HALF OF 2000

We believe the Federal Reserve is at or near the end of its cycle of interest
rate increases. We are monitoring economic and market conditions carefully and
plan to lengthen our maturities a bit when rates begin to come down. By doing
this, we can retain the benefits of today's higher rates for a longer period of
time. As usual, we continue to compare rates paid on various money market
instruments in order to take advantage of the best offerings.

Sincerely,

Fixed Income Team

            NOTES TO FINANCIAL STATEMENTS

JUNE 30, 2000

1. SIGNIFICANT ACCOUNTING POLICIES
    Security Income Fund, Security Municipal Bond Fund and Security Cash Fund
(the Funds) are registered under the Investment Company Act of 1940, as amended,
as diversified open-end management investment companies. The shares of Security
Income Fund are currently issued in multiple series, with each series, in
effect, representing a separate Fund. The Income Fund is required to account for
each series separately and to allocate general expenses to each series based on
the net asset value of each series. Class A shares are sold with a sales charge
at the time of purchase. Class A shares are not subject to a sales charge when
they are redeemed, except that purchases of Class A shares of $1 million or more
sold without a front-end sales charge are subject to a contingent deferred sales
charge if redeemed within one year of purchase. Class B and Class C shares are
offered without a front-end sales charge but incur additional class-specific
expenses. Redemptions of the shares within five years of acquisition for Class B
and within one year of acquisition for Class C incur a contingent deferred sales
charge. The following is a summary of the significant accounting policies
followed by the Funds in the preparation of their financial statements.
    A. SECURITY VALUATION -- Valuations of Security Income and Municipal Bond
Funds' securities are supplied by pricing services approved by the Board of
Directors. Securities listed or traded on a national securities exchange are
valued on the basis of the last sales price. If there are no sales on a
particular day, then the securities are valued at the last bid price. Securities
for which market quotations are not readily available are valued by a pricing
service considering securities with similar yields, quality, type of issue,
coupon, duration and rating. If there is no bid price or if the bid price is
deemed to be unsatisfactory by the Board of Directors or by the Funds'
investment manager, then the securities are valued in good faith by such method
as the Board of Directors determines will reflect the fair value. The Funds'
officers, under the general supervision of the Board of Directors, regularly
review procedures used by, and valuations provided by, the pricing service.
    Cash Fund, by approval of the Board of Directors, utilizes the amortized
cost method for valuing portfolio securities, whereby all investments are valued
by reference to their acquisition cost as adjusted for amortization of premium
or accretion of discount.
    B. OPTIONS -- Diversified Income Series and the High Yield Series may
purchase put and call options and write such options on a covered basis on
securities that are traded on recognized securities exchanges and
over-the-counter markets. Call and put options on securities give the holder the
right to purchase or sell, respectively (and the writer of the obligation to
sell or purchase), a security at a specified price, until a certain date. The
primary risks associated with the use of options are an imperfect correlation
between the change in market value of the securities held by the Series and the
price of the option, the possibility of an illiquid market, and the inability of
the counter-party to meet the terms of the contract.
    The premium received for a written option is recorded as an asset, with an
equal liability which is marked to market based on the option's quoted daily
settlement price. Fluctuations in the value of such instruments are recorded as
unrealized appreciation (depreciation) until terminated, at which time realized
gains and losses are recognized.
    C. SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions are
accounted for on the date the securities are purchased or sold. Realized gains
and losses are reported on an identified cost basis. Interest income is
recognized on the accrual basis. Premiums and discounts (except original issue
discounts) on debt securities are not amortized, except Security Municipal Bond
Fund, which amortizes premiums.
    D. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are
recorded on the ex-dividend date. The character of distributions made during the
year from net investment income or net realized gains may differ from their
ultimate characterization for federal income tax purposes. These differences are
primarily due to the treatment of paydown gains and losses on mortgage-backed
securities.
    E. TAXES -- The Funds complied with the requirements of the Internal Revenue
Code applicable to regulated investment companies and distributed all of their
taxable net income and net realized gains sufficient to relieve them from all,
or substantially all, federal income, excise and state income taxes. Therefore,
no provision for federal or state income tax is required.
    F. EARNINGS CREDITS -- Under the fee schedule with the custodian, the Funds
earn credits based on overnight custody cash balances. These credits are
utilized to reduce related custodial expenses. The custodian fees disclosed in
the statement of operations do not reflect the reduction in expense from the
related earnings credits.
    G. USE OF ESTIMATES -- The preparation of financial statements in conformity
with accounting principles generally accepted in the United States 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 increases and
decreases in net assets from operations during the reporting period. Actual
results could differ from those estimates.

2. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES
    Management fees are payable to Security Management Company, LLC (SMC) under
investment advisory contracts at an annual rate of .50 of 1% of the average
daily net assets of Municipal Bond Fund and Cash Fund; .35 of 1% of the average
daily net assets for Diversified Income Series and .60% of 1% of the average
daily net assets of the High Yield Series. For the period 12/31/99 to 2/4/00,
management fees for the Diversified Income Series were .50 of 1% of the average
daily net assets. SMC pays Salomon Brothers Asset Management, Inc., an annual
fee equal to .22% of the average daily net assets of Security Municipal Bond
Fund for management services provided to the Fund. The investment advisory
contract for Security Income Fund provides that the total annual expenses of

each Series of the Fund (including management fees and custodian fees net of
earnings credits, but excluding interest, taxes, brokerage commissions,
extraordinary expenses and distribution fees paid under the Class B and Class C
distribution plans) will not exceed the level of expenses which Income Fund is
permitted to bear under the most restrictive expense limitation imposed by any
state in which shares of the Fund are qualified for sale. For the six months
ended June 30, 2000, SMC agreed to limit the total expenses of Diversified
Income Series to an annual rate of 0.95% of the average daily net asset value of
Class A shares and 1.70% of Class B shares and Class C shares. SMC also agreed
to limit the total expenses of the High Yield Series to 2.0% for Class A Shares
and 2.75% for Class B shares. The investment advisory contract for Municipal
Bond Fund provides that the total annual expenses of the Fund, exclusive of
interest, taxes, Rule 12b-1 fees, brokerage fees and commissions and
extraordinary expenses, will not exceed an amount equal to an annual rate of
1.0% of the average net assets of the Fund as calculated on a daily basis. The
investment advisory contract for Security Cash Fund provides that the total
annual expenses of the Fund, exclusive of interest, taxes, brokerage fees and
commissions and extraordinary expenses, will not exceed an amount equal to an
annual rate of 1% of the average net assets of the Fund as calculated on a daily
basis.
    The Funds have entered into contracts with SMC for transfer agent services
and certain other administrative services which SMC provides to the Funds. SMC
is paid an annual fixed charge per account and shareholder and dividend
transaction fees.
    As the administrative agent for the Funds, SMC performs administrative
functions, such as regulatory filings, bookkeeping, accounting and pricing
functions for the Funds. For this service SMC receives on an annual basis, a fee
of 0.9% of the average daily net assets of Diversified Income Series, High Yield
Series, and Municipal Bond Fund and .045% of the average daily net assets of
Cash Fund calculated daily and payable monthly.
    Security Income and Municipal Bond Funds have adopted Distribution Plans
related to the offering of Class B shares and Security Income Fund has adopted a
Distribution Plan relating to the Offering of Class C shares, each such
Distribution Plan has been adopted pursuant to Rule 12b-1 of the Investment
Company Act of 1940. The Plans provide for payments at an annual rate of 1.0% of
the average daily net assets of Class B shares and Class C shares, respectively,
Class A shares of Security Income Fund and Security Municipal Bond Fund incur
12b-1 distribution fees at an annual rate of .25% of the average daily net
assets of each Series.
    Security Distributors, Inc. (SDI), a wholly-owned subsidiary of Security
Benefit Group, Inc., a financial services holding company, is national
distributor for Security Income and Municipal Bond Funds. SDI received net
underwriting commissions on sales of Class A shares and contingent deferred
sales charges (CDSC) on redemptions occurring within 5 years of the date of
purchase of Class B shares and within one year of the date of purchase of Class
C shares, after allowances to brokers and dealers for the six months ended June
30, 2000, in the amounts presented below:
