                               Portfolio Manager

TO OUR SHAREHOLDERS:

Series A of the SBL Fund - Equity Series returned 4.33% in the 12-month period
ending December 31, 2005, lagging the benchmark S&P 500 Index's return of 4.91%
and the Series' peer group median return of 5.42%. Like 2004, the markets
favored lower quality, higher beta, and smaller market cap companies. In such
environments, we tend to under perform. While disappointing, we believe that our
approach delivers performance over the long-term.

Our approach to managing the Series is based on our investment philosophy
described below.

We understand a company's growth potential over the long-term based on our
bottom up fundamental investment process. We invest today based on future
potential. We concentrate our investments in companies with sustainable
competitive advantages when they are undervalued. Companies must demonstrate
management ability by consistently adding shareholder value. They must have
strong financial positions and be well positioned for growth. We are patient
buyers and sellers focused on the long-term, and we take advantage of investor
uncertainty and short-term thinking.

For this Series, we apply this philosophy to a broad range of both growth and
value names.

FINANCIAL STOCKS TOP PERFORMERS

The Series' financial sector holdings were up 10% compared to 6% for the Index.
Positions in First Marblehead Corporation, American International Group (AIG),
and American Express Company contributed positively to the Series. Both First
Marblehead Corporation and AIG had short-term issues surrounding business
practices and subsequent management changes. Our view was that these were
temporary issues that did not significantly diminish each company's competitive
position or growth prospects. These are good examples of our ability to
capitalize on market overreactions by allowing us to invest in what we believe
are superior businesses at very reasonable prices. American Express Company
benefited from the spin-off of its investment advisory business and solid
execution within its core charge and credit card operations.

TECHNOLOGY AND UTILITIES DISAPPOINTING

Technology stocks continued to be volatile with 2005 being a recovery year
following a poor 2004. Positive results from ADC Telecommunications, Inc. (ADC),
up 19%, were not able to offset not owning Apple Computer or Hewlett Packard.
ADC benefited from the broadband build out, while Apple had tremendous success
with new product launches. Hewlett Packard benefited from a new management team
and a strategy change that allows it to compete more effectively.

The utilities sector was up 17% in 2005 following strong performance in the
prior two years as well. Utilities continued to perform due to their attractive
dividend yields, reductions made in their operating risk profiles, de-leveraging
their balance sheets, and the anticipation of an improving regulatory
environment. For some time, we have felt that all of these catalysts have
already been priced into the sector; therefore we had no exposure. We feel
comfortable with our under weight position due to a belief that some of these
variables will reverse themselves in the future.

2006 MARKET OUTLOOK

Though we are positive on the equity market for 2006, we do have several
near-term concerns. The most significant, in our opinion, is the spending
capacity of the U.S. consumer. Above average consumer spending trends have
persisted as a result of favorable monetary and fiscal policies. These favorable
policy trends are now being reversed. Additionally, higher energy prices will
continue to weigh heavily on the consumer as we move through the winter heating
season.

We continue to look for opportunities that are long-term in nature and benefit
from both an attractive valuation and the ability to improve their fundamental
competitive position.

We believe that investing is a long-term pursuit that requires patience and a
consistent approach. Dollar cost averaging is a sound way to build long-term
value(1). We recognize there are many investment fund alternatives available
today and thank you for your business and the confidence you place in us.

Sincerely,


Mark A. Mitchell
Portfolio Manager

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 6.07%.

(2)  Expenses are equal to the Series annualized expense ratio 0.89% multiplied
     by the average account value over the period, multiplied by 184/365 (to
     reflect the one-half year period).

TO OUR SHAREHOLDERS:

Series B of the SBL Fund - Large Cap Value Series returned 10.52% in the
12-month period ended December 31, 2005, beating the benchmark Russell 1000
Value Index's return of 7.05% and the Series' peer group median return of 5.41%.
The S&P 500 BARRA Value index's return for the same period was 4.00%.

Security Management Company assumed investment management responsibilities on
June 30, 2005. The following comments are based on results for the six months
ended on December 31, 2005.

The Series' was up 11.15% compared to up 5.20% for the Russell 1000 Value Index
for the six-month period ended December 31, 2005. Strong stock selection drove
excellent results in the second half of 2005.

Our approach to managing the Series is based on our investment philosophy
described below.

We understand a company's growth potential over the long-term based on our
bottom up fundamental investment process. We invest today based on future
potential. We concentrate our investments in companies that have or can create
sustainable competitive advantages when they are undervalued. Companies must
demonstrate management ability by consistently adding shareholder value. They
must have strong financial positions and be well positioned for growth. We are
patient buyers and sellers focused on the long-term, and we take advantage of
investor uncertainty and short-term thinking.

For this Series, we apply this philosophy to a broad range of value names.

INDUSTRIALS AND ENERGY STOCKS TOP PERFORMERS IN LAST SIX MONTHS

The industrial sector holdings were up 26% compared to 9% for the Index.
McDermott International, Inc. appreciated 112%, driven by a favorable legacy
asbestos litigation ruling and strong demand for its energy infrastructure
construction related services. Shaw Group, Inc. was up 35% as a result of strong
demand for its infrastructure construction related services.

Energy stocks did well in the 3rd and 4th quarters as a result of continued
commodity price increases. Specifically, our energy sector return of 15%
bettered the index return of 6%. These strong results were do in part to owning
Sasol, Ltd. up 34%, Halliburton Company up 30%, and Williams Companies, Inc., up
22%.

TECHNOLOGY DISAPPOINTING OVER LAST SIX MONTHS

The Series' technology sector holdings, up 4%, lagged the benchmark's sector
return of 15%. Unisys Corporation negatively impacted our performance as the
company lowered its growth expectations due in part to a more difficult
competitive environment.

OVERVIEW OF FIRST 6 MONTHS BY PREVIOUS MANAGER

The following comments from Dreyfus cover the results prior to the investment
manager change on June 30, 2005.

The portfolio outperformed the index, S&P BARRA Value in the consumer staples,
utilities, industrials, information technology, and financials sectors. The
portfolio lagged the benchmark in the materials, energy, health care, consumer
discretionary, and telecommunication services sectors.

Within consumer staples, shares of grocer Safeway rose over 14% on improved
year-over-year sales growth and better-than-expected earnings.

Aiding the energy sector were Exxon Mobil and ConocoPhillips. Exxon Mobil, which
is not held in the benchmark, advanced over 13% and was the most significant
contributor. The company produced record 4th quarter 2004 earnings, which
translated into a 1st quarter 2005 earnings nearly 30% higher than street
estimates and drove a 20% surge in the stock price. Shares weakened during the
second quarter, but Exxon was still a top performer in the 1st half of 2005.
ConocoPhilips performed well during the period because of higher energy prices,
improved refining margins, and a solid 1st quarter earnings report released in
later April.

Within consumer discretionary, Advance Auto Parts continues to take market
share, drive traffic in newly remodeled stores, grow new stores, and expand
margins. It has grown earnings well over 20% year-over-year. And despite losing
two CEO's in the space of 15 months, Boeing benefited from the combination of
increased commercial airline orders and military hardware sales, and is expected
to raise revenues over the previous year.

Within industrials, Tyco negatively impacted the sector from a slight downward
revision in guidance for 2005 earnings and free cash flow. While this is
negative news, the thesis for owning the stock remains. Tyco is well positioned
for accelerating top line growth, steady margin expansion and significant share
repurchases. Clear Channel Communications has embarked on a major program to
reduce advertising inventory. This should ultimately make for a much healthier
radio industry. Unfortunately, weak current demand has muted impact of lower
supply and helped to hinder the consumer discretionary sector.

Within materials, International Paper was a poor performer, as demand for
industrial packaging materials and printing paper fell off - so much so that a
lack of orders forced more downtime at the company. And IBM fell short of 1st
quarter earnings expectations by 5 cents, citing soft economic conditions, while
concurrently announcing that the company will begin to expense equity
compensation and options.

2006 MARKET OUTLOOK

Though we are positive on the equity market for 2006, we do have several
near-term concerns.

The most significant, in our opinion, is the spending capacity of the U.S.
consumer. Above average consumer spending trends have persisted as a result of
favorable monetary and fiscal policies. These favorable policy trends are now
being reversed. Additionally, higher energy prices will continue to weigh
heavily on the consumer as we move through the winter heating season.

We continue to look for opportunities that are long-term in nature and benefit
from both an attractive valuation and the ability to improve their fundamental
competitive position.

We believe that investing is a long-term pursuit that requires patience and a
consistent approach. Dollar cost averaging is a sound way to build long-term
value(1). We recognize there are many investment fund alternatives available
today and thank you for your business and the confidence you place in us.

Sincerely,

Mark A. Mitchell, Portfolio Manager

The chart above assumes a hypothetical $10,000 investment in Series B (Large Cap
Value Series) on December 31, 1995 and reflects the fees and expenses of Series
B. Effective July 1, 2005, Series B changed its benchmark to the Russell 1000
Value Index. The Investment Manager has determined that the Russell 1000 Value
Index is a more appropriate index because the Russell 1000 Value Index more
closely reflects the types of securities in which the Series invests and thus
provides shareholders with a more appropriate benchmark against which to compare
the Series' performance. The S&P 500/Barra Value Index is a
capitalization-weighted index of all stocks in the S&P 50 Index that have low
price-to-book ratios. It is designed so that approximately 50% of the market
capitalization of the S&P 500 Index is in the S&P Barra Value Index. The Russell
1000 Value Index is an unmanaged index representing the performance of those
Russell 1000 Index companies with lower price-to-book ratios and lower
forecasted growth values.

(1)  Performance figures do not reflect fees and expenses associated with an
     investment in variable insurance products offered by Security Benefit Life

     expenses, performance would have been lower. Shares of a Series of SBL Fund
     are available only through the purchase of such products.

The performance data quoted above represents past performance. Past performance
is not predictive of future performance. The 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.

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

   Hypothetical   1,000.00        1,021.17           4.08


(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 10.07%.

(2)  Expenses are equal to the Series annualized expense ratio 0.80% multiplied
     by the average account value over the period, multiplied by 184/365 (to
     reflect the one-half year period).

TO OUR SHAREHOLDERS:

Once again, the main theme in the money market arena was the increase in the
federal funds rate by the Federal Reserve Bank's monetary policy committee. In
2005, the rate was raised 200 basis points, and yields of money market
instruments rose in step accordingly. Series C of the SBL Fund - Money Market
Series returned 2.70% for the year ended December 31, 2005.

Aside from higher short-term interest rates, the past year proved positive for
credit issuers. Companies continued to report solid cash flows and strong
earnings driven by the overall strength of the economy. One area of concern is
the growing tendency of companies to use their excess cash flow to increase
dividends or repurchase shares rather than bolster their credit quality.

CHARACTERISTICS OF PORTFOLIO ASSETS

At December 31, 2005 the average maturity of the holdings in Series C was 42
days, which was in precise alignment with the benchmark. This proved to be a
beneficial strategy to enhance the yield while providing the avenue to take
advantage of additional value adding opportunities.

The yield curve for money market instruments maintained an upward trend during
2005, thus facilitating our ability to select additional yield broadly along the
maturity spectrum and among various types of instruments. At year-end,
approximately 52% of the Series was invested in Commercial Paper, 30% in
Floating Rate securities (which includes Corporate and U.S. Government-Backed),
11% in U.S. Government/ Agency obligations, 4% in funding agreements, and 3% in
Bankers Acceptances.

OUTLOOK FOR 2006

Overall, the economy grew at a healthy pace in 2005, despite significant
increases in commodity prices, 2 percent higher short term interest rates, and
the hurricanes that battered New Orleans and other areas surrounding the Gulf of
Mexico. We expect the economy in 2006 to moderate to a 3% or lower real growth
rate that will be more attributable to business rather than consumer spending.
Therefore, our expectations for Federal Fund rates are to remain at 4.50% after
the January meeting of the Federal Reserve monetary policy committee.

As always, we will continue to monitor the economic and market conditions when
deciding portfolio strategies and will adjust the asset mix and maturity
structure in the portfolio accordingly.

Thank you for your investment in Series C. We appreciate the confidence that
you have placed in us and remain focused on achieving the Series' investment
goals.

Sincerely,


Christi Fletcher
Portfolio Manager

     are available only through the purchase of such products.

The performance data quoted above represents past performance. Past performance
is not predictive of future performance. The investment return and principal
value of an investment will fluctuate so that an investor's shares, when

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

   Hypothetical                     1,000.00        1,021.78          3.47


(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 1.58%.

(2)  Expenses are equal to the Series annualized expense ratio 0.68% multiplied
     by the average account value over the period, multiplied by 184/365 (to
     reflect the one-half year period).

                               TO OUR SHAREHOLDERS

For the 12-month period ending December 31, 2005, Series D of the SBL Fund -
Global Series posted a total return of 13.53% versus 9.49% return for its
benchmark, MSCI World Index.

It is important to bear in mind that the following discussion of the stocks that
added to or detracted from the Series' performance is provided to illustrate our
investment approach rather than suggest any attempt to make a country, sector or
thematic wager.

TOP PERFORMERS

The Series benefited from a number of holdings, mostly for company-specific
reasons. Hyundai Heavy Industries, the world's largest shipbuilder, was one of
the Series' best performing stocks. A long-term holding for the Series, Hyundai
Heavy stock was initially purchased based on the assessment that the average
tanker age of the world fleet was high and that the shipping industry's move
toward double-hulled tankers would create demand for new ship construction. The
initial investment in the stock was at a very reasonable price due to various
market concerns, including the company's ownership of non-core businesses. The
issues have now been resolved, and the stock's price more than doubled during
the reporting period.

Series performance was also enhanced by the investment in AMD, whose new dual
core processor chip achieved significant traction in the server market ahead of
Intel's competitive offering. The market's skepticism of AMD's competitive
position turned to acceptance over the period, leading to a rise in the stock's
price. Two additional contributors to the Series performance were Husky Energy,
Inc., an oil reserves company, and Transocean, Inc., an oil driller, both of
which benefited from the rising price of oil and natural gas.

DISAPPOINTMENTS

A few of the Series' holdings hindered returns during the reporting period,
including JDS Uniphase Corporation, an optical components company. The stock had
been initially purchased in previous years based on the evaluation that there
was a significant opportunity for a turnaround and that the risk was reflected
in its stock price. However, the turnaround never materialized and the stock was
sold.

Another negative contributor was Vodafone. As one of the Series' largest
holdings, Vodafone has yet to deliver performance in line with expectations. A
slow market in Europe, a greater-than-expected expenditure by the company in
Japan and a realized tax change all contributed to hurt expected results. A
lengthening of the sales cycle in video conferencing technology led to earnings
disappointments at Tandberg, one of the poorest performers in the Series.
However, we continue to view its technology as having merit with adoption of it
in the coming year. Holdings in International Game Technology, the world's
largest manufacturer of casino gaming machines, also disappointed. The company's
earnings growth did not meet investors' expectations and, consequently, its
stock price fell. Nevertheless, the company is a leader in its industry and its
long-term prospects remain strong. We, therefore, made a modest additional
investment in the company at its reasonably-priced stock level.

Our investment approach is to seek secular long-term growth opportunities that
are available at reasonable prices and hold them for a three-to-five year
timeframe in order to realize significant appreciation. We continue to seek such
opportunities as we move forward into 2006.

Sincerely,


William L. Wilby

(1)  Performance figures do not reflect fees and expenses associated with an
     investment in variable insurance products offered by Security Benefit Life
     Insurance Company. If returns had taken into account these fees and
     expenses, performance would have been lower. Shares of a Series of SBL Fund
     are available only through the purchase of such products.

The performance data quoted above represents past performance. Past performance
is not predictive of future performance. The 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.

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 14.08%.

(2)  Expenses are equal to the Series annualized expense ratio 1.25% multiplied
     by the average account value over the period, multiplied by 184/365 (to
     reflect the one-half year period).

TO OUR SHAREHOLDERS:

2005 was an unusual year in the fixed income market. Long-term interest rates
declined and economic growth was resilient despite eight consecutive interest
rate increases by the Federal Reserve Bank that cumulatively equaled 2 percent.
Two factors were instrumental in restricting an increase in longer maturity
rates: core CPI (Consumer Price Index excluding food and fuel) was contained
despite sharply rising prices of commodities, including oil and gold; and
purchases of U.S. bonds by foreign investors set a record high. Nevertheless,
bond returns were lackluster in 2005 with the broad bond market return as
represented by the Lehman Brothers Aggregate Index posting a total of 2.43% for
the year. Correspondingly, the SBL E -Diversified Income Series advanced only
1.85% for the 12-month period ended December 31, 2005.

FACTORS AFFECTING PERFORMANCE IN 2005

The sluggish bond market returns resulted from the Federal Reserve Bank's
interest rate increases that caused the interest rates of short and intermediate
maturity government bonds to move up during the year and adversely impacted the
equity market. Also contributing to the bond market's sub-par performance was
the negative impact from the credit rating agencies' downgrades of General
Motors and Ford. These actions resulted in the elimination of two very large
issuers from the investment grade indices. Corporate bonds under-performed
government bonds in 2005 despite earning a higher yield premium for the added
credit risk and the reasonably healthy economic environment.

During 2005, the Series was positioned more heavily in shorter maturity bonds to
mitigate the impact of rising interest rates. This strategy was correct in that
most rates did rise; however, shorter rates rose more steeply than intermediate
and longer rates, causing the Series to lose value due to the yield curve
effect. The yield curve flattened throughout the year benefiting portfolios with
a significant barbell structure, or over-weighting of long and short maturities
and under-weighting of intermediate maturities. The Series was slightly
over-weighted in corporate bonds to take advantage of the robust economy and a
low volatility corporate yield spread environment. Though the under-weighting of
GM and Ford was beneficial to the Series, the under-weighting of long maturity
U.S. Treasury and agency bonds was problematic. The long maturities in the
portfolio were invested primarily in corporate bonds, which under-performed long
maturity government bonds.

THE COMPOSITION OF PORTFOLIO ASSETS

At the end of the year, the Series held 38% in mortgage-backed securities, 3% in
asset-backed and commercial mortgage-backed securities, 28% in corporate issues,
17% in U.S.

Treasury issues, 8% in federal agency issues, and 6% in cash. This portfolio
composition is over-weighted in corporate bonds and mortgage-backed securities
and under-weighted in Treasury and Agency issues relative to the benchmark.

OUTLOOK FOR 2006

The economy grew at a healthy pace in 2005, despite very large increases in
commodity prices, 2 percent higher short-term interest rates, and the hurricanes
which battered New Orleans and other areas surrounding the Gulf of Mexico. We
expect the economy in 2006 to moderate to a 3% or lower real growth rate that
will be more attributable to business rather than consumer spending. Over the
past few years, consumer spending has been the main driver of the U.S. economy
due to an accommodative Federal Reserve Bank's policy. The low interest rate
environment led to large amounts of equity withdrawal from increased home
values, which then fueled consumer demand. The monetary accommodation has now
been removed after thirteen straight rate increases, leaving short-term interest
rates at or near long-term interest rates for the first time since early 2000.
Consumer spending from home equity extraction will subside in 2006 due to higher
mortgage rates and slower home price appreciation. However, employment gains
seem to be improving, which should keep consumer spending at a reasonable pace.

While the flat or inverted yield curve condition has led to slow economic growth
in the past, we do not expect significant weakness in 2006. In the past, the
curve inverted due to Federal Reserve hikes of the short-term rates well above
the inflation rate and above rising long-term interest rates. We believe the
current flatness of the yield curve is partly due to foreign purchases of U.S.
debt as well as to demand from pension funds for longer maturity debt to match
long liabilities in defined benefit plans. Growth should remain healthy in the
low long-term interest rate environment.

We expect shorter-term rates to remain around 4.50% after the January meeting of
the Federal Reserve but expect longer-term rates to continue to rise. As a
result, longer maturities will be under-weighted in the Series while shorter
maturities will be over-weighted to benefit from a steepening in the slope of
the yield curve. Interest rate volatility will most likely remain low, thereby
mitigating the need for call protection as part of the portfolio strategy. We
expect credit risk premiums to continue to increase gradually but to remain
below long-term averages for 2006.

In the coming year we are most concerned with event risk in investment grade
corporate bonds. Due to the outlook described above, we will continue to hold
larger-than-index weights in mortgage-backed securities, asset-backed
securities, and corporate debt for the yield advantage, but will avoid corporate
issuers who, we believe, are prone to increase the debt in their capital
structure.

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

Hypothetical      1,000.00        1,021.32          3.92


(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was (0.09%).

(2)  Expenses are equal to the Series annualized expense ratio 0.77% (net of
     expense waivers) multiplied by the average account value over the period,
     multiplied by 184/365 (to reflect the one-half year period).

TO OUR SHAREHOLDERS:

Series G of the SBL Fund - Large Cap Growth Series returned 3.33% for the
12-month period ended December 31, 2005, lagging the benchmark Russell 1000
Growth Index's return of 5.26% and the Series' peer group median return of
6.79%. The last few years, the market favored lower quality, higher beta stocks.
In such environments, we tend to under perform. While disappointing, we believe
that our approach delivers performance over the long term.

Our approach to managing the Series is based on our investment philosophy
described below.

We understand a company's growth potential over the long-term based on our
bottom up fundamental investment process. We invest today based on future
potential. We concentrate our investments in companies with sustainable
competitive advantages when they are undervalued. Companies must demonstrate
management ability by consistently adding shareholder value. They must have
strong financial positions and be well positioned for growth. We are patient
buyers and sellers focused on the long-term, and we take advantage of investor
uncertainty and short-term thinking.

For this Series, we apply this philosophy to a broad range of growth companies.

INDUSTRIAL AND FINANCIAL STOCKS TOP PERFORMERS

The Series' industrial sector holdings were up 6% compared to up 4% for the
Index. Positions in J.B. Hunt Transport Services, Inc. (JB Hunt) and W.W.
Grainger, Inc. (Grainger) contributed positively to the Series' performance. JB
Hunt, up over 25%, benefited from solid trucking demand in a supply constrained
industry. Grainger, up 14%, was driven by strong economic growth and progress on
internal productivity initiatives.

Within the financial sector, First Marblehead Corporation was up over 48%. The
company experienced short-term issues surrounding business practices and
subsequent management changes. Our view was that these were temporary issues
that did not significantly diminish the company's competitive position or growth
prospects. This is a good example of our ability to capitalize on market
overreactions by allowing us to invest in what we believe is a superior business
at a very reasonable price.

HEALTHCARE AND TECHNOLOGY DISAPPOINTING

Healthcare, as a sector overall, under performed the index. Zimmer Holdings,
Inc. (Zimmer) and Boston Scientific both had negative impact on the Series.
Zimmer was down over 15% as a result of concerns regarding the industry pricing
environment and its longer term growth prospects. We believe these are
short-term issues that will be more than offset by Zimmer's strong competitive
position in the health industry. Boston Scientific was down over 24% as a result
of concerns regarding its long-term growth prospects and declining market share
in the drug eluting stent market in the U.S.

Technology, as a sector overall, produced limited returns in 2005. However,
there were good performers at the company level. Apple Computers, Inc. (Apple),
up 123%, benefited significantly from the excitement around new product launches
in its flagship iPod digital music player and notebook computer lines. While we
believe Apple is a good company, it does not meet our valuation criteria.

2006 MARKET OUTLOOK

Though we are positive on the equity market for 2006, we do have several
near-term concerns. The most significant, in our opinion, is the spending
capacity of the U.S. consumer. Above average consumer spending trends have
persisted as a result of favorable monetary and fiscal policies. These favorable
policy trends are now being reversed. Additionally, higher energy prices will
continue to weigh heavily on the consumer as we move through the winter heating
season.

We continue to look for opportunities that are long-term in nature and benefit
from both an attractive valuation and the ability to improve their fundamental
competitive positions.

We believe that investing is a long-term pursuit that requires patience and a
consistent approach. Dollar cost averaging is a sound way to build long-term
value(1). We recognize there are many investment fund alternatives available
today and thank you for your business and the confidence you place in us.

Sincerely,


Mark A. Mitchell
Portfolio Manager

     expenses, performance would have been lower. Shares of a Series of SBL Fund
     are available only through the purchase of such products.

The performance data quoted above represents past performance. Past performance
is not predictive of future performance. The 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.

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 5.68%.

(2)  Expenses are equal to the Series annualized expense ratio (net of expense
     waivers and earnings credits) of 0.94% multiplied by the average account
     value over the period, multiplied by 184/365 (to reflect the one-half year
     period).

TO OUR SHAREHOLDERS:

Series H of the SBL Fund - Enhanced Index Series posted a total return of 5.04%
for the 12-month period ended December 31, 2005 versus 4.91% for its benchmark,
the S&P 500 Index.

Though U.S. equity markets posted gains in 2005, there were a number of factors
that contributed to the overall weak returns. The Federal Reserve Bank raised
interest rates eight times during the year, bringing the total to thirteen 25
basis point increases since the tightening cycle began in June 2004. As of the
end of 2005, the federal funds rate stood at 4.25%. As oil prices and the dollar
strengthened, fresh inflation concerns and speculative demand drove gold prices
to their highest level in nearly 25 years, rising 25% and peaking at $540.90
toward the end of December. In the third quarter of 2005, the impact of
hurricanes Katrina and Rita in the U.S. pushed crude oil prices briefly above
$71 before retreating during the fourth quarter and finishing the year at $61.

INVESTMENT MANAGEMENT CRITERIA

The Series is managed using a proprietary quantitative stock selection model
that assigns each company in the S&P 500 an expected return based upon multiple
factors. These factors are based on four broad characteristics: Valuation (is
the stock reasonably priced?), Momentum (Price and Earnings Momentum), Earnings
(Earnings Quality and Stability) and Management Signals (signals given by
management and insiders trading in company stock). Additionally, there are
strict risk constraints that limit deviations from the benchmark with respect to
individual stocks, sectors, industries, style and size.

KEYS TO THE SERIES' GAIN

Driving the Series' positive performance in 2005 were the portfolio's exposures
to companies with strong price momentum, high earnings yield, and positive
earnings surprises -- all factors that performed well across a broad number of
sectors.

During 2005, the market rewarded moderately valued securities that displayed
attractive growth characteristics, especially within the energy and utilities
sectors. The energy sector returned 31.3% for the year while the utilities
sector returned 16.8%. The Series' bottom up stock selection model and portfolio
construction methodology are designed to ensure the portfolio will have
exposures to all sectors, relying on stock selection within sectors to enhance
returns relative to the benchmark. For example, within the energy sector the
model recommended overweight positions in Burlington Resources and Nabors
Industries, both stocks with reasonable valuations, favorable earnings
indicators and strong price momentum characteristics. These stocks returned
99.3% and 47.7% respectively, helped by sharply rising energy prices in the wake
of the hurricanes and strong global demand.

Less favorable in the energy sector was the model's recommendation of
underweight in Valero Energy Corporation, which was rated low because of rich
valuations but that nevertheless appreciated in the strong energy markets,
rising 128% during the year.

In 2006, we expect to see continued solid economic growth and constrained
inflation, which will present an attractive backdrop for equities.

We express our gratitude to our shareholders for their confidence in the Series
and assure them that we will continue to apply our disciplined, quantitative
approach while adhering to our strict risk control process.

Sincerely,


Enhanced Index Team

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 5.39%.

(2)  Expenses are equal to the Series annualized expense ratio (net of expense
     waivers) of 0.78% multiplied by the average account value over the period,
     multiplied by 184/365 (to reflect the one-half year period).

TO OUR SHAREHOLDERS:

Series J of the SBL Fund - Mid Cap Growth Series returned 7.82% in the 12-month
period ended December 31, 2005, lagging the benchmark Russell 2500 Growth
Index's return of 8.17% and the Series' peer group median return of 11.10%. A
smaller average market capitalization vs. benchmark and peers as well as
challenging stock selection in a few sectors proved problematic for the Series.

Our approach with the Series is to seek securities of companies that are able to
grow and/or reinvest in increasingly profitable ventures and hold them over 3-5
years to capture the best part of the improvements in profits or profitability.
We are focused in investing in securities when we find opportunities, with our
individual position sizes reflecting the magnitude and the confidence in the
opportunity. For this Series, we target securities of companies that appear
likely to generate above average profitability at prices that, as of yet, do not
reflect that potential.

ENERGY AND FINANCIALS LED GAINS

An overweight position in energy vs. the benchmark aided performance. The energy
sector gained 57% during the year and easily outdistanced any other sector. The
Series held an average 20% in energy vs. 6.7% for the benchmark.

By limiting exposure in the financial sector, performance was helped. Northern
Trust gained 13% in a sector that posted negative total returns. Northern Trust,
which has a large recurring fee revenue component, benefited in the rising
interest rate environment.

HEALTHCARE AND INDUSTRIALS LAG

Difficult stock selection in healthcare hurt the Series. The holdings in this
sector lost 27% in value while the benchmark gained 7%. The Series bias towards
early stage biotechnology and medical device companies hurt due mostly to
product development setbacks and delays. Ligand Pharmaceuticals declined 40% as
the company delayed filing its quarterly report and also experienced
disappointing sales of one of its lead products, Avinza. Ligand remains one of
the few biotechs with numerous product opportunities and is also approaching
profitability. At current prices, we are quite content to continue holding the
stock. Sciclone Pharmaceuticals, another biotechnology holding, showed weak
results for Zadaxin, a hepatitis C drug in Phase 3 trials. With this product no
longer viable, the valuation reflected more than adequately the company's
potential in its other early stage products; hence the position was sold.

Stock selection in industrials was also sub par. Exposure in this sector while
gaining 8.6% lagged the 13.8% gain of the benchmark. Power One fell 32.5% as the
company restructured and had delays despite being on the verge of a significant
product release. 2006 should be a crucial year for the company and we continue
to hold the position in anticipation of better times.

OUTLOOK FOR 2006

The stock market has been surprisingly buoyant the past year given rising energy
prices and restrictive Federal Reserve Bank policies. Logic would tend to
suggest that an unusually conservative positioning would be prudent. However,
companies with high earnings stability and visibility currently have high
valuations suggesting that the market has already priced in this outlook. In
addition, the out-performance of value stocks over the last few years may also
reflect this conservative tendency in the market. Given this view, the Series
plans to continue to under-weight in the traditionally stable sectors such as
finance, consumer discretionary, and consumer staples. With the sizable move in
the energy sector, the Series has been trimming exposure slightly.

At present, we are finding that the most compelling opportunities lie in the
industrial and technology sectors of the market. Specifically, we favor
companies in the water, wastewater, telecommunications equipment and highway
development industries. In addition, many of the new commitments have also
tended to the larger end of our market capitalization spectrum.

On behalf of SBL Fund - Series J - Mid Cap Growth Series, thank you for trusting
your investment with us. We are excited to see what opportunities present
themselves over 2006.

Sincerely,


James P. Schier,
Senior Portfolio Manager

The chart above assumes a hypothetical $10,000 investment in Series J (Mid Cap
Growth Series) on December 31, 1995 and reflects the fees and expenses of Series
J. The Investment Adviser has determined that the Russell 2500 Growth Index is a
more appropriate index than the S&P MidCap 400/Barra Growth Index, which is
created by Standard & Poor's and Barra by dividing the S&P MidCap 400 Index
equally between growth and value based upon a price to book value calculation
because the Russell 2500 Growth Index more closely reflects the types of
securities in which the Series invests and thus provides shareholders with a
more appropriate benchmark against which to compare the Series' performance. The
Russell 2500 Growth Index is an unmanaged index that measures the performance of
securities of small-to-mid U.S. companies with greater-than-average growth
orientation.

(1)  Performance figures do not reflect fees and expenses associated with an
     investment in variable insurance products offered by Security Benefit Life

     expenses, performance would have been lower. Shares of a Series of SBL Fund
     are available only through the purchase of such products.

The performance data quoted above represents past performance. Past performance
is not predictive of future performance. The 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.

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 10.95%.

(2)  Expenses are equal to the Series annualized expense ratio 0.90% multiplied
     by the average account value over the period, multiplied by 184/365 (to
     reflect the one-half year period).

TO OUR SHAREHOLDERS:

Series N of SBL Fund - Managed Asset Allocation Series seeks to provide a high
level of total return. The Series pursues its objective by normally investing
approximately 60% of its total assets in U.S. and foreign common stocks and 40%
in fixed-income securities. The mix may vary over shorter time periods, with the
fixed income portion between 30%-50% of assets and the equity portion between
50%-70% of assets. As the sub-advisor, we generally concentrate common stock
investments in larger, established companies but may invest in small and
medium-sized companies with good growth prospects.

ENVIRONMENT

U.S. stocks produced a third consecutive year of positive returns in 2005, but
gains were more modest than in the prior two years. Equities sagged through
April amid concerns about inflation and rising short-term interest rates. Stocks
worked their way higher as the year progressed, supported by firm economic and
corporate earnings growth and merger activity. The year ended on a weak note,
however, as investors became concerned that economic growth would slow in 2006.

U.S. bonds trailed domestic stocks in 2005. Returns were modestly positive, as
falling bond prices offset income. The Federal Reserve Bank raised the federal
funds target rate in eight quarter-point increments - from 2.25% to 4.25%, a
level not seen in four years - but hinted after the most recent rate increase in
mid-December that it may be nearing the end of its rate tightening program,
which began in June 2004 when the federal fund's rate was 1.00%.

Non-U.S. stocks outperformed domestic stocks in 2005, despite the fact that a
stronger greenback against major foreign currencies eroded returns to U.S.
investors. Japanese shares produced robust returns in U.S. dollar terms and
reached five-year highs, whereas European bourses generated solid yet more
modest gains.

We overweighted stocks relative to bonds throughout 2005. We ended the year with
a 6% overweight. The overweight aided returns, as stocks outperformed bonds.
Within our bond portfolio, we are underweight in high yield bonds, given their
rich valuations. We are roughly neutral in international stocks. The Series'
allocation to international stocks also aided relative results, given the strong
returns for non-U.S. equities.

PERFORMANCE

The Series returned 4.35% (net of fees) for the one-year period ended December
31, 2005, versus the 4.00% return of a weighted benchmark comprising 60% in the
S&P 500 Index and 40% in the Lehman Brothers U.S. Aggregate Index. The Series
was helped by overweighting stocks versus bonds in a period in which stocks
outperformed relative to bonds. The S&P 500 returned 4.91% over the past 12
months and the Lehman Brothers U.S. Aggregate Index returned 2.43%.

PORTFOLIO HIGHLIGHTS

The portfolio currently has a 6% overweight in equities relative to bonds.
Although corporate profit growth remains solid and should be supportive of
equities, it is likely to continue decelerating given the cumulative impact of
higher interest rates and energy prices,

In light of relatively rich valuations, the Series is underweight in high yield
versus investment grade bonds. In general, high yield fundamentals remain
favorable, with good corporate profits and historically low corporate default
rates.

The Series is roughly neutral in non-U.S. equity markets. Valuations are
reasonable in EAFE-related markets, as productivity increases are helping to
maintain earnings growth despite modest revenue growth.

OUTLOOK

We do not necessarily believe that the equity markets will outperform over the
next three to six months, but we believe that, given the prospects for upward
pressure on interest rates consistent with a maturing economic cycle, equities
should fare better than bonds over the next couple of years.

Thank you for investing in the SBL N - Managed Asset Allocation Series.

Sincerely,


Edmund N. Notzon

(1)  Performance figures do not reflect fees and expenses associated with an
     investment in variable insurance products offered by Security Benefit Life

     expenses, performance would have been lower. Shares of a Series of SBL Fund
     are available only through the purchase of such products.

The performance data quoted above represents past performance. Past performance
is not predictive of future performance. The investment return and principal
value of an investment will fluctuate so that an investor's shares, when

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

   Hypothetical   1,000.00        1,018.10          7.17


(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 3.83%.

(2)  Expenses are equal to the Series annualized expense ratio (net of earnings
     credits) of 1.41% multiplied by the average account value over the period,
     multiplied by 184/365 (to reflect the one-half year period).

TO OUR SHAREHOLDERS:

Series O of the SBL Fund - Equity Income Series seeks to provide substantial
dividend income and also capital appreciation. The  Series
pursues its objective by  investing, under normal market
conditions, at least 80% of its net assets in common stocks, with 65% in the
common stocks of well-established companies paying above-average dividends. As
sub-advisor, we typically employ a value-oriented strategy in selecting
investments for the Series. Our research team identifies companies that appear
to be undervalued by various measures and may be temporarily out of favor, but
have good prospects for capital appreciation and dividend growth.

ENVIRONMENT

The widely followed Dow Jones Industrial Average was essentially flat for the
year, while most of the other major indices posted modest gains. Energy
dominated the equities markets in 2005 with a powerful advance, and utilities
were the only other sector to provide a double-digit return. Consumer
discretionary and telecommunications services were the worst sectors over the
year, affected by a weak auto sector and competition from wireless companies,
respectively.

PERFORMANCE REVIEW

The Series delivered a moderate return of 3.74% for 2005, performing in line
with the 4.91% return of the S&P 500 Index. An overweighting in the weak
consumer discretionary sector, particularly media, along with poor stock
selection within the group detracted from relative results. New York Times
Company, Comcast Corporation, Tribune Company, and Dow Jones & Company, Inc.
were four of the Series' top ten detractors from performance over the year. We
remain sanguine on the group, however, and believe it will provide significant
value in the long term based on the unique content these companies provide. Also
of note in the consumer discretionary sector is Eastman Kodak Company, one of
the top five detractors from performance. The company suffered from
disappointing growth in its digital products business and declining sales in its
traditional film business, prompting the rating agencies to cut the company's
unsecured debt to junk status. Other areas of disappointment were materials and
chemicals where International Paper and International Flavors & Fragrance,
respectively, hindered results.

Positive contributors included information technology, the Series' best relative
contributor due mostly to stock selection. Within computers and peripherals,
Hewlett-Packard Company was a major relative contributor and one of the largest
absolute contributors, driven by solid earnings and revenues. International
Business Machines Corporation also had a strong impact on relative performance
due in part to a timely purchase. Within communications equipment, Motorola,
Inc. and Nokia were beneficial, the former benefiting from new high-end cell
phone products and a stock repurchase program, and the latter from strong global
demand for handsets and an increase in market share. We have been taking profits
in Hewlett-Packard, Texas Instruments, and other stocks that have done well and
reinvesting the proceeds in strong companies with relatively low valuations such
as Cisco Systems, Inc.

The industrial and business services sector was another significant contributor
to the Series' relative return. The Series' industrial conglomerate holdings did
well, and an overweight in roads and rails also aided results. Railroad stock,
Union Pacific Corporation, was one of the five largest contributors to overall
performance thanks to stronger yields and gains from real estate sales.

OUTLOOK

Corporations are enjoying strong profits and cash flow, which together provide
the incentive for new corporate investments. We believe earnings will continue
to grow in 2006, although at a more moderate pace due to lower consumer spending
reflecting higher energy prices and mortgage rates. Stock market fundamentals
remain sound at the beginning of the year.

Globalization, competition, and high productivity growth are restraining
inflation, which reduces pressure on the Federal Reserve Bank to raise
short-term rates much higher. Our worst case scenario calls for moderate stock
market gains during the next 12 months, although significant corporate liquidity
could set the stage for better performance than we saw in 2005. We expect
companies to increase their dividend payments in 2006 and merger and acquisition
activity to remain robust, which could provide additional ballast for stocks. As
always, we will focus on reasonably valued stocks with relatively high dividend
yields in our ongoing effort to provide value for investors.

Thank you for investing in the Series O of the SBL Fund-Equity Income Series.

Sincerely,

Brian C. Rogers, Portfolio Manager

(1)  Performance figures do not reflect fees and expenses associated with an
     investment in variable insurance products offered by Security Benefit Life
     Insurance Company. If returns had taken into account these fees and
     expenses, performance would have been lower. Shares of a Series of SBL Fund
     are available only through the purchase of such products.

The performance data quoted above represents past performance. Past performance
is not predictive of future performance. The 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.

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 3.46%.

(2)  Expenses are equal to the Series annualized expense ratio (net of earnings
     credits) of 1.15% multiplied by the average account value over the period,
     multiplied by 184/365 (to reflect the one-half year period).

     expenses, performance would have been lower. Shares of a series of SBL Fund
     are available only through the purchase of such products.

(b)  Total expense information reflects expense ratios absent fund expense
     reductions by the Investment Manager.

(c)  Net expense information reflects the expense ratios after custodian
     earnings credits.

TO OUR SHAREHOLDERS:

The high yield market, coming off two successive strong years of double-digit
percentage gains, was unable to continue its streak in 2005. The U.S. economy's
robust growth allowed corporations to increase profits and to further improve
their balance sheets, which helped keep the corporate default rate low. Although
the economic environment was favorable and corporate fundamentals improved, the
high yield market, as measured by the Lehman Brothers High Yield Index, was only
able to produce a lackluster return of 2.74% for the year. Series P of the SBL
Fund - High Yield Series was up 3.81% for the 12-month period ended December 31,
2005.

LACKLUSTER PERFORMANCE IN 2005

Although the Series' return was in the low single-digits, it performed in-line
with other competing fixed income asset classes. Specifically, government bonds
returned 2.6%, higher quality corporate bonds 2.0%, and leveraged bank loans
4.6%, while the S&P 500 could only muster a 3.0% return. The sluggish returns
resulted from the Federal Reserve Bank's eight interest rate increases during
the year which caused government bond interest rates to move up slightly during
the year and adversely impacted the equity market. Also contributing to the high
yield market's sub-par performance was the negative impact from the credit
rating agencies' downgrades of General Motors and Ford. These actions resulted
in two very large issuers being added to the high yield universe, thereby
increasing the automotive sector's weight to around 14% of the high yield
market. This sector alone was down 11.4% for the year.

During 2005, the Series was positioned in shorter maturity bonds to mitigate
rising interest rates and was slightly overweighted in lower quality bonds to
take advantage of the robust economy and a low corporate default rate. The high
yield corporate default rate, after reaching bottom at mid-year, slightly
increased during the second half of the year to finish at 2.2%, down from 2.7%
at year-end 2004. High yield corporate bond spreads, after nearly reaching
historic lows in the first quarter, trended wider throughout the year thereby
causing bond prices to decline slightly.

SHORTER MATURITY BONDS PROVIDED STABLE INCOME

The Series' core holdings in shorter maturity bonds provided solid income
generation and stable current yields for the Series during the year. These
shorter maturity bonds are not as sensitive to interest rate movements.
Therefore, as rates moved higher during the year, these bonds lost little, if
any, of their principal value while collecting their interest payments. One of
the Series' largest holdings, Qwest Communications, was one of these bonds and
it produced an 11% return.

SPECIFIC PORTFOLIO INVESTMENTS ENHANCED RETURNS

The Series was able to enhance its return by investing in some lower quality,
higher yielding securities. As the economy continued to grow robustly, many of
the Series' holdings benefited. One of the Series' best contributors was
Worldspan, a travel services company, which returned 18% as air travel and
lodging soared. Another company leveraged to the economy and residential and
commercial construction boom, United Rentals, an equipment rental company,
returned 17%. Capitalizing on rising energy prices, an oil service company, Oil
States International returned 25%. Finally, the Series' continued overweight to
the wireless telecommunications sector boosted returns due in part to its
holding in Rural Cellular which produced an 11% return.

AVOIDING AUTOMOTIVE AND PAPER SECTORS PROVED SUCCESSFUL

The Series' underweight positions in both the automotive and paper sectors
helped the Series to outperform its benchmark index. The auto sector performed
poorly because of the weak operating results from GM and Ford and consequently
their suppliers were negatively impacted as well. Some of the auto suppliers
filed for bankruptcy protection, and others were perilously close. The paper
sector also performed poorly during 2005. Higher energy prices, rising labor and
freight costs and the strengthening Canadian dollar put pressure on this sector
throughout the year.

OUTLOOK AND STRATEGY FOR 2006

For 2006, the economy is expected to maintain its growth rate during the first
half and weaken slightly into year-end. The corporate default rate is expected
to slightly increase throughout the year and possibly reach 3.5% by year-end,
but still remain well below the long run average of around 5%. The significant
increase in mergers and acquisitions and leveraged buy-outs may help the high
yield bonds for those companies being acquired. However, new issuance as a
result of these leveraging transactions will be of much lower quality and these
highly levered issuers will be much less able to weather an economic slowdown.
This lower quality issuance may cause the default rate to increase over the next
few years. Therefore, the Series will continue to hold shorter maturity bonds
and opportunistically add selective lower quality securities to enhance returns.
Finally, given the high yield market's outlook, we believe it is poised to offer
attractive returns versus other investment choices in the upcoming year.

Sincerely,

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 3.36%.

(2)  Expenses are equal to the Series annualized expense ratio 0.97% multiplied

(a)  Total return does not take into account any of the expenses associated with
     an investment in variable insurance products offered by Security Benefit
     Life Insurance Company. If total return had taken into account these
     expenses, performance would have been lower. Shares of a series of SBL Fund
     are available only through the purchase of such products.

(b)  As required, effective January 1, 2001, the Funds adopted the provisions of
     the AICPA Audit and Accounting Guide for Investment Companies and began
     amortizing premiums on fixed income securities. The effect of this change
     for the period ended December 31, 2001 was to decrease net investment
     income per share by less than 1/2 of a cent, increase net realized and
     unrealized gains and losses per share by less than 1/2 of a cent and
     increase (decrease) the ratio of net investment income to average net
     assets from (0.02%) to 0.12%. Per share, ratios and supplemental data for
     periods prior to January 1, 2001 have not been restated to reflect this
     change in presentation.

     highlights of Series K. The assets of Series K were acquired by Series P on
     August 27, 2002.

TO OUR SHAREHOLDERS:

The equity markets got off to a rough start in 2005, but finished the year
firmly in positive territory. Series Q of SBL Fund - Small Cap Value Series
outperformed the Russell 2000 for the year. The Series returned 14.51% for the
year, versus the index's return of 4.55%. Soaring real-estate prices,
devastating storms and the rising values of commodities, magnified due to the
hurricane effects, marked the year. In the fourth quarter, the economy and
corporate profits continued to exhibit solid growth and oil prices eased from
all time highs reached earlier in the year. The small-cap value asset class had
positive performance during the quarter, but fell short relative to other asset
classes. Growth stocks started to creep back into the limelight, while mid and
large cap stocks outperformed small cap names.

The materials sector was the main area of positive contribution to the Series
performance. The overweighting in materials, as well as superior stock selection
within the metals and mining sector added significant value to the Series
portfolio. During the quarter, we witnessed a continued rise in the price of
commodities, particularly gold and silver. Gold reached multi-decade highs and
positively impacted stocks. The team continues to favor metals and mining
stocks, as these companies appear to be relatively cheap, exhibit positive cash
flows, and have clean balance sheets.

Technology was also an area that contributed positively to performance. Although
the portfolio was slightly underweighted relative to the benchmark, good stock
selection added value. Electronic equipment and semiconductor names in
particular produced exceptional returns during the year. The portfolio is
currently underweighted in the semiconductor industry, however we are actively
looking for opportunities within this area.

The financial sector produced mixed results. Stock selection within the area
enhanced performance, however the portfolio's underweighted exposure negatively
impacted relative performance. Insurance and commercial bank holdings were
strong during the fourth quarter, which provided alpha to the portfolio.
However, a significant underweighting in real estate investment trusts (REITs)
and commercial banks relative to the benchmark detracted from performance. The
Series' portfolio has remained underweight to financials for some time. Our
investment approach, which identifies undervalued stocks, tends not to lead us
to these names, especially at current valuations.

The Series' overweighted exposure to the energy sector was the primary area of
detraction during the fourth quarter. However, the sector has been a key driver
of performance throughout much of the year. Stock selection was weak across the
board during the quarter as energy prices declined from highs experienced
earlier in the year. Despite short-term disruptions, the team believes energy
names will add value as the supply/demand equation for oil and natural gas
remains favorable in the long-term.

Looking ahead, the team is somewhat cautious in the near-term about the
small-cap value asset class as money flows to growth stocks. However, over the
long-term we believe the asset class remains attractive as many small cap names
continue to be underfollowed. We will continue working to exploit inefficiencies
within the small-cap value asset class, as we believe the current markets reward
active managers with strong stock picking abilities. We remain focused on
identifying investment opportunities in stocks with quality management and
strong fundamentals that we believe are attractively valued.

Sincerely,

(1)  Performance figures do not reflect fees and expenses associated with an
     investment in variable insurance products offered by Security Benefit Life
     Insurance Company. If returns had taken into account these fees and
     expenses, performance would have been lower. Shares of a Series of SBL Fund
     are available only through the purchase of such products.

The performance data quoted above represents past performance. Past performance
is not predictive of future performance. The 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.

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

   Hypothetical      1,000.00        1,019.00         6.26


(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 13.83%.

(2)  Expenses are equal to the Series annualized expense ratio (net of earnings
     credits) of 1.23% multiplied by the average account value over the period,
     multiplied by 184/365 (to reflect the one-half year period).

(a)  Total return does not take into account any of the expenses associated with
     an investment in variable insurance products offered by Security Benefit
     Life Insurance Company. If total return had taken into account these
     expenses, performance would have been lower. Shares of a series of SBL Fund
     are available only through the purchase of such products.

(b)  Total expense information reflects expense ratios absent fund expense
     reductions by the Investment Manager.

(c)  Net expense information reflects the expense ratios after custodian
     earnings credits.

TO OUR SHAREHOLDERS:

2005 produced solid returns. SBL S - Social Awareness Series returned 5.00% in
the 12-month period ending December 31, 2005, slightly ahead of the benchmark,
S&P 500 Index's return of 4.91% and slightly below the Series' peer group median
return of 5.42%. For comparison purposes, the DSI 400 Index was up 3.00% for the
same period. The performance was driven primarily by strong stock selection
offset by not participating in the energy sector's strong performance due to
social criteria.

Our approach to managing the Series is based on our investment philosophy
described below.

We understand a company's growth potential over the long-term based on our
bottom up fundamental investment process. We invest today based on future
potential. We concentrate our investments in companies with sustainable
competitive advantages when they are undervalued. Companies must demonstrate
management ability by consistently adding shareholder value. They must have
strong financial positions and be well positioned for growth. We are patient
buyers and sellers focused on the long-term, and we take advantage of investor
uncertainty and short-term thinking.

Once we determine that companies meet our investment criteria, we review them to
ensure they meet our social criteria as well. We employ this philosophy to a
universe of value and growth companies.

INDUSTRIAL AND CONSUMER STAPLES STOCKS TOP PERFORMERS

The industrial sector was up over 18% for the Series versus up 2% for the
benchmark. Shaw Group, Inc. and J.B. Hunt Transport Services, Inc. (JB Hunt)
were the major drivers within the sector. Shaw Group was up 63% as a result of
continued worldwide economic growth and the corresponding demand for its
infrastructure related services. JB Hunt was up 29%, benefiting from solid
trucking demand in a supply constrained industry.

Within consumer staples, CVS Corporation (CVS) and Costco Wholesale Corporation
(Costco) were up 18% and 15% respectively. CVS benefited from continued
execution in its core drug store business and good progress in the integration
of Eckard, an acquisition completed in July 2004. Costco was positively impacted
by solid execution within its core business of retail warehouse clubs.

ENERGY AND TECHNOLOGY DISAPPOINTING

The energy sector was up over 47% for the period driven by rapidly increasing
commodity prices. Many energy-related companies have environmental concerns that
do not meet our social screening criteria. These limitations are not in place in
the benchmark (S&P 500), or the core peer group we use for comparison purposes.

Technology, as a sector overall, produced limited returns in 2005. However,
there were good performers at the company level. Apple, up 123%, benefited
significantly from the excitement around new product launches in its flagship
iPod digital music player and notebook computer lines. While we believe Apple is
a good company, it does not meet our valuation criteria.

2006 MARKET OUTLOOK

Though we are positive on the equity market for 2006, we do have several
near-term concerns. The most significant, in our opinion, is the spending
capacity of the U.S. consumer. Above average consumer spending trends have
persisted as a result of favorable monetary and fiscal policies. These favorable
policy trends are now being reversed. Additionally, higher energy prices will
continue to weigh heavily on the consumer as we move through the winter heating
season.

We continue to look for opportunities that are long-term in nature and benefit
from both an attractive valuation and the ability to improve their fundamental
competitive positions.

We believe that investing is a long-term pursuit that requires patience and a
consistent approach. Dollar cost averaging is a sound way to build long-term
value(1). We recognize there are many investment fund alternatives available
today and thank you for your business and the confidence you place in us.

Sincerely,

Mark A. Mitchell
Portfolio Manager

The chart above assumes a hypothetical $10,000 investment in Series S (Social
Awareness Series) on December 31, 1995 and reflects the fees and expenses of
Series S. Series S is changing its benchmark index to the S&P 500 because, among
other reasons, the Domini Social 400 is not as widely utilized and reported an
index as the S&P 500, performance attribution analysis of the Domini Social 400
is no longer available to the Series and the change to the S&P 500 allows
shareholders to compare the Series' performance to that of a broader measure of
the stock market's overall performance as compared to the Domini 400. The Domini
Social Index, modeled on the S&P 500 Index, is a socially screened
capitalization weighted index of 400 common stocks. The S&P 500 Index is a
capitalization-weighted index composed of 500 selected common stocks that
represent the broad domestic economy and is a widely recognized unmanaged index
of market performance.

(1)  Performance figures do not reflect fees and expenses associated with an
     investment in variable insurance products offered by Security Benefit Life
     Insurance Company. If returns had taken into account these fees and
     expenses, performance would have been lower. Shares of a Series of SBL Fund
     are available only through the purchase of such products.

The performance data quoted above represents past performance. Past performance
is not predictive of future performance. The 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.

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 6.68%.

(2)  Expenses are equal to the Series annualized expense ratio 0.91% multiplied
     by the average account value over the period, multiplied by 184/365 (to
     reflect the one-half year period).

TO OUR SHAREHOLDERS:

Series V of SBL Fund - Mid Cap Value Series returned 16.21% in the 12-month
period that ended December 31, 2005, beating the benchmark Russell 2500 Value
Index's return of 7.74% and out James P.Schier performing the Series' peer group
median return of 9.40%. Strong stock selection and sector positioning drove
excellent results in 2005.

Our approach with Series V is to seek appreciable securities of companies that
are able to grow and/or reinvest in increasingly profitable ventures and hold
them over 3-5 years to capture the better part of the improvements in
profitability. We are focused on investing in securities when we find
opportunities, with our individual position sizes reflecting the magnitude and
the confidence in the opportunity. For this Series, we target securities
generally priced at or below a market multiple that are able to increase their
return on capital over time.

INDUSTRIALS, ENERGY AND FINANCIALS LED GAINS

For the Series, the industrial sector was the largest contributor to results,
gaining 40% vs. 9.8% for the benchmark. Energy infrastructure names such as
McDermott International, Inc. and Shaw Group, Inc. were the biggest contributors
gaining 142%, and 63% respectively. McDermott's marine construction business
received renewed interest after Hurricane Katrina and progress on asbestos
liability litigation prompted strong interest in the name. Shaw Group
experienced rapid backlog growth in utility base load construction and refinery
projects.

The energy sector was also a big contributor. Arch Coal gained 125%. The stock
rallied in sympathy with a robust coal market. Prior to this year, coal lagged
the appreciation of other fossil fuels. In addition, efforts to make coal
generation a cleaner source appear to be gaining traction in the market. This
feature serves to boost its attractiveness as a fuel.

Good stock selection in financials also benefited the Series as stocks in this
sector rose 17% vs. 5.5% for the benchmark. W.R. Berkley Corporation, a
specialty property and casualty insurer, gained 52%. The company reported
improving financial metrics despite a difficult catastrophe year for the
industry. United Rentals, Inc. gained 27% and First Marblehead Corporation
gained 23%. Both were hurt by short term events that were eventually sorted out
by the market.

TECHNOLOGY AND HEALTHCARE LAG

During 2005 stock selection in technology was difficult. The Series' holdings in
this sector declined 14%. The fiber optic component supplier Avanex Corporation
fell 58% as restructuring costs and cash burn fears were compounded with a
slower than expected up tick in its business. Merix Corporation, Inc. declined
37% as the market questioned its purchase of a high volume Asian circuit board
manufacturer.

Health care also provided turbulence. Hooper Holmes, Inc. declined 56% as the
porta-medic business continues to languish. The company also experienced a lack
of progress in a promised diversification effort. Hooper continues to have a
strong business position in its niche and generates free cash flow. The Series
continues to patiently hold this issue.

OUTLOOK FOR 2006

The stock market has been surprisingly buoyant the past year given rising energy
prices and restrictive Federal Reserve Bank policies. Logic would tend to
suggest that an unusually conservative positioning would be prudent. However,
companies with high earnings stability and visibility currently have high
valuations suggesting that the market has already priced in this outlook. In
addition, the out-performance of value stocks over the last few years may also
reflect this conservative tendency in the market. Given this view, the Series
plans to continue to under-weight the traditionally stable sectors such as
finance, consumer discretionary, and consumer staples. With the sizable move in
the energy sector, the Series has been trimming exposure slightly.

At present, we are finding that the most compelling opportunities lie in the
industrial and technology sectors of the market. Specifically, we like companies
in the water, wastewater, telecomm equipment and highway development industries.
In addition, many of the new commitments have also tended to the larger end of
our market capitalization spectrum.

On behalf of the Series, thank you for trusting your investment with us. We are
excited to see what opportunities present themselves over 2006.

Sincerely,


James P. Schier
Senior Portfolio Manager

                            $10,000 SINCE INCEPTION

The chart above assumes a hypothetical $10,000 investment in Series V (Mid Cap
Value Series) on May 1, 1997 (date of inception) and reflects the fees and
expenses of Series V. Series V changed its benchmark index to the Russell 2500
Value Index. The Investment Adviser has determined that the Russell 2500 Value
Index is a more appropriate index than the S&P MidCap 400/Barra Value Index,
which is created by Standard & Poor's and Barra by dividing the S&P MidCap 400
Index equally between growth and value based upon a price-to-book value
calculation, because the Russell 2500 Value Index more closely reflects the
types of securities in which the Series invests and thus provides shareholders
with a more appropriate benchmark against which to compare the Series'
performance. The S&P MidCap 400/Barra Value Index, which is created by Standard
& Poor's and Barra by dividing the S&P MidCap 400 Index equally between growth
and value based upon a price-to-book value calculation. The Russell 2500 Value
Index is an unmanaged index that measures the performance of Securities of
small-to-mid cap U.S. companies with greater-than-average value orientation.

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 13.21%.

(2)  Expenses are equal to the Series annualized expense ratio 0.91% multiplied
     by the average account value over the period, multiplied by 184/365 (to
     reflect the one-half year period).

TO OUR SHAREHOLDERS:

For the 12-month period ended December 31, 2005, Series W of the SBL Fund - Main
Street Growth & Income(R) Series provided an average annual total return of
5.39%, outpacing the 4.91% return of its benchmark, the S&P 500 Index. The
Series' strong relative performance can be attributed to the securities selected
that more Portfolio Manager than offset the weakness among mega-cap stocks in
2005.

However, the Series' absolute returns were limited by relatively lackluster
conditions in the U.S. stock market during 2005. Although corporate earnings
continued to grow in a steadily expanding economy, investors became concerned
early in the reporting period that stronger-than-expected economic growth might
cause the Federal Reserve Board to raise short-term interest rates more than
many investors previously expected, potentially eroding profit margins. In
addition, investors worried during the spring and summer that soaring energy
prices might adversely affect corporate earnings. Finally, the disruptions
caused by the hurricanes gave investors cause for concern in the fall.

2005 INVESTMENT STRATEGY

The investment model guides us toward companies displaying certain desirable
criteria: high-quality earnings, attractive valuations and solid momentum behind
them. Based on these and other factors, the model led to establishing a modest
overweighting in the energy sector. The Series' energy holdings had strong
balance sheets, were highly profitable and offered attractive valuations, and
therefore performed well in the last six months of the year. By contrast, the
model led to the reduction of the portfolio's weighting in the information
technology sector. At the start of 2005, technology stocks comprised the largest
area of overweight, in part to benefit from seasonal trends. By period end,
technology became one of the largest underweights relative to the S&P 500 as the
model suggested high quality, less speculative firms would fare better. Although
various market sectors are regularly overweighted and underweighted, risk is
managed by keeping the weightings reasonably close to those of the index as well
as by avoiding excessive concentration in any individual holding.

ENERGY HOLDINGS SHOWED GAINS; INFORMATION TECHNOLOGY AND TELECOMMUNICATIONS
DISAPPOINTING

The Series' overweighted position and security selection strategy in the energy
sector proved to be particularly rewarding. In addition to identifying winners
among U.S.-based energy companies, the Series received strong contributions from
several Canadian energy firms. The Series' performance also benefited from its
relatively light exposure to consumer discretionary companies, which provided
disappointing results.

The Series' slightly overweighted exposure to information technology stocks
detracted modestly from performance, due primarily to poor returns from some of
the sector's larger companies. The Series' holdings of very large
telecommunications companies also held back returns.

Finally, the Series benefited during 2005 from a better balance across
capitalization ranges. Early in the year, emphasis on mega-cap stocks was
reduced in favor of large-cap stocks, thus avoiding the full brunt of relative
weakness among the market's largest companies.

SECOND-HALF SHIFTS IN SECTOR INVESTMENTS

During the second half of 2005 significant changes occurred in the ratings
assigned by the statistical models to individual stocks. The shifts are
attributable to seasonal factors, in which more growth-oriented,
economically-sensitive stocks historically have tended to fare better than
value-oriented shares during the fourth and first quarters of the year. As a
result, information technology companies replaced financial and energy stocks as
the Series' most overweighted market sector. Nonetheless, the Series is still
overweighted in energy and it is now overweighted in healthcare. All other
sectors are underweighted relative to its benchmark, S&P 500 Index, including
the financial sector which was the most overweighted sector in mid-2005.

In 2005, equity returns were particularly strong among mid-cap stocks. Excluding
the mega-cap stocks, large-cap stocks posted better returns in 2005 than either
small-cap or micro-cap stocks. However, mega-cap stocks continued to languish
but micro-cap stocks also faltered. Lower-quality stocks maintained their edge
over higher quality stocks, as investors favored smaller, more speculative
stocks over the well-established, multinational giants that comprise the
market's largest companies. It is important to note, however, that the market's
year-end rally was strongest among mega-cap stocks, suggesting that, should this
trend be sustained, blue-chip companies may be returning to favor.

Although we do not make investment decisions based on a macroeconomic outlook,
we are encouraged by signs that larger-cap stocks may finally be returning to
favor. Regardless of the market's direction in 2006, we will continue to employ
our quantitative models when constructing a broadly diversified, fully invested
stock fund.

Sincerely,


Nikolaos Monoyios, Portfolio Manager

(1)  Performance figures do not reflect fees and expenses associated with an
     investment in variable insurance products offered by Security Benefit Life
     Insurance Company. If returns had taken into account these fees and
     expenses, performance would have been lower. Shares of a Series of SBL Fund
     are available only through the purchase of such products.

The performance data quoted above represents past performance. Past performance
is not predictive of future performance. The 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.

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 5.39%.

(2)  Expenses are equal to the Series annualized expense ratio (net of earnings
     credits) of 1.24% multiplied by the average account value over the period,
     multiplied by 184/365 (to reflect the one-half year period).

TO OUR SHAREHOLDERS:

In 2005, Series X of the SBL Fund - Small Cap Growth Series outperformed its
benchmark, the Russell 2000 Growth Index, rising a strong Bill Wolfenden 8.10%
gross of fees (7.51% net of Portfolio Manager fees) compared to a 4.15% increase
in the benchmark.

The Series' continued to reap performance rewards from various companies in the
technology sector in 2005. The Series' technology holdings are broadly
diversified across different industries and use technology in varied
applications. An example is Digitas, Inc. a fast growing marketing services
company that is benefiting from large Fortune 1000 companies moving more
advertising dollars to various Internet- and Web-based mediums. New business
growth has helped drive Digitas revenue growth north of 20%. The company
produces strong gross margins that we believe will continue to fuel earnings
growth into 2006 and beyond.

The Series' benefited from a number of strong performing stocks in the financial
services sector. Two small-cap property and casualty insurance companies
provided strong returns as the calamities of late 2005 rippled through the
insurance industry. As capacity has been withdrawn from the market, pricing in
some segments has remained very strong. Tower Group, Inc., a specialty property
and casualty insurer, contributed strong returns in 2005. Tower Group focuses on
underserved niches, primarily in the greater New York markets. The company went
public in late 2004 and the stock has been a strong performer in the portfolio.

The Series' was negatively impacted by health care in 2005. Some of the poorly
performing names included QLT and VaxGen. Historically, the Series has had
strong performance in the health care sector, but 2005 was very disappointing.
The holdings in this sector have been repositioned over the past couple months,
hoping to have much better attribution from this important growth sector in
2006.

Energy has been a significant contributor to many small-cap growth managers'
returns in 2005. In fact, energy contributed more than 50% of the return to the
Russell 2000 Growth Index in calendar year 2005. While we have been bullish on
segments of energy for two years, we have taken our weighting down to slightly
under the benchmark over the last few quarters. Closing out the year, the Series
owned a number of energy-related positions, with an emphasis on energy service
companies like Superior Energy Services, Inc. and Oil States International, Inc.
While these service providers sold off in the fourth quarter, dragging down
returns in the short run, we believe they are well positioned to benefit from
continued ramp up in drilling for new oil and natural gas reserves.

Historically rising interest rates and rapidly rising oil prices have been bad
for small companies, but small-caps overcame these events in 2005. Stocks also
persevered through major hurricanes, continued unrest in Iraq, and sporadic
worldwide terrorist activities. If interest rates can stabilize and oil prices
decline or moderate, then 2006 could be another solid year for small-cap stocks.
That said, the Series is positioned today for flat to modestly positive Gross
Domestic Product in 2006. The portfolio holds companies offering unique
products, services, and/or business models that can grow sales and earnings by
creating new markets or capturing market share. We appreciate your continued
support.

Sincerely,

(1)  Performance figures do not reflect fees and expenses associated with an
     investment in variable insurance products offered by Security Benefit Life
     Insurance Company. If returns had taken into account these fees and
     expenses, performance would have been lower. Shares of a Series of SBL Fund
     are available only through the purchase of such products.

The performance data quoted above represents past performance. Past performance
is not predictive of future performance. The 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.

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

   Hypothetical      1,000.00        1,019.26          6.01


(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 7.95%.

(2)  Expenses are equal to the Series annualized expense ratio (net of earnings
     credits) of 1.18% multiplied by the average account value over the period,
     multiplied by 184/365 (to reflect the one-half year period).

                                Mark A. Mitchell
                                Portfolio Manager

TO OUR SHAREHOLDERS:

Series Y of SBL Fund - Select 25 Series returned 11.75% in the 12-month period
ended December 31, 2005, beating the benchmark Russell 1000 Growth Index's
return of 5.26% and out performing the Series' peer group median return of
6.83%. Strong stock selection and sector positioning drove excellent results in
2005.

Our approach to managing Series Y is based on our investment philosophy
described below.

We understand a company's growth potential over the long-term based on our
bottom up fundamental investment process. We invest today based on future
potential. We concentrate our investments in companies with sustainable
competitive advantages when they are undervalued. Companies must demonstrate
management ability by consistently adding shareholder value. They must have
strong financial positions and be well positioned for growth. We are patient
buyers and sellers focused on the long-term, and we take advantage of investor
uncertainty and short-term thinking.

This philosophy is applied to a broad range of growth names. Our research
analysts recommend their favorite stocks based on this analysis. We then narrow
the list down to our favorite 25-30 names that get included in the portfolio.

ENERGY AND INDUSTRIALS STOCKS TOP PERFORMERS

The Series' energy sector holdings were up 41% for the year. The sector
benefited significantly as a result of the increase in the price of crude oil.
Positions in BJ Services Company (BJ Services), Williams Companies, Inc.
(Williams) and KFx, Inc. contributed positively to the Series. BJ Services and
Williams, up 59% and 44% respectively, benefited from rising oil prices. KFx
appreciated 18% as a result of progress being made in the commercialization of
the company's proprietary clean coal technology.

The industrial sector was up over 23% for the Series versus up 4% for the
benchmark. Shaw Group, Inc. and J.B. Hunt Services, Inc. (JB Hunt) were the
major drivers within the sector. Shaw Group was up 63% as a result of continued
worldwide economic growth and the corresponding demand for its infrastructure
related services. JB Hunt was up 17%, benefiting from solid trucking demand in a
supply constrained industry.

HEALTHCARE AND CONSUMER SECTORS DISAPPOINT

Healthcare, as a sector overall, under performed the index. Strong performance
by Amgen, Inc. was partially offset by the negative impact of Boston Scientific.
Amgen was up over 22% as a result of posting solid operating results and
diminishing fears regarding the reimbursement environment. Boston Scientific was
down over 18% as a result of concerns regarding its long-term growth prospects
and declining market share in the drug eluting stent market in the U.S.

Both the consumer discretionary and consumer staples sectors under performed
their respective benchmark. Harley Davidson, down 18%, and Wal-Mart, down 10%,
impacted the Series negatively. Harley Davidson was down as a result of lowering
its 2005 production schedule and general concerns over a slowdown in consumer
spending. Wal-Mart, too, was negatively impacted by consumer slowdown fears as
well as questions concerning its long-term growth prospects.

2006 MARKET OUTLOOK

Though we are positive on the equity market for 2006, we do have several
near-term concerns. The most significant, in our opinion, is the spending
capacity of the U.S. consumer. Above average consumer spending trends have
persisted as a result of favorable monetary and fiscal policies. These favorable
policy trends are now being reversed. Additionally, higher energy prices will
continue to weigh heavily on the consumer as we move through the winter heating
season.

We continue to look for opportunities that are long-term in nature and benefit
from both an attractive valuation and the ability to improve their fundamental
competitive position.

We believe that investing is a long-term pursuit that requires patience and a
consistent approach. Dollar cost averaging is a sound way to build long-term
value(1). We recognize there are many investment fund alternatives available
today and thank you for your business and the confidence you place in us.

Sincerely,


Mark A. Mitchell
Portfolio Manager

                             $10,000 SINCE INCEPTION

The chart above assumes a hypothetical $10,000 investment in Series Y (Select 25
Series) on May 3, 1999 (date of inception), and reflects the fees and expenses
of Series Y. Series Y changed its benchmark index to the Russell 1000 Growth
Index. The Investment Manager has determined that the Russell 1000 Growth Index
is a more appropriate index than the S&P 500 Index, which is a
capitalization-weighted index composed of 500 selected common stocks that
represent the broad domestic economy and is a widely recognized unmanaged index
of market performance, because the Russell 1000 Growth Index more closely
reflects the types of securities in which the Series invests and thus provides
shareholders with a more appropriate benchmark against which to compare the
Series' performance. The S&P 500 Index is a capitalization-weighted index
composed of 500 selected common stocks that represent the broad domestic economy
and is a widely recognized unmanaged index of market performance. The Russell
1000 Growth Index is an unmanaged capitalization-weighted index which includes
stocks incorporated in the United States and its territories and measures the
performance of the Russell 1000 companies with higher price-to-book ratios and
higher forecasted growth values.

(1)  Performance figures do not reflect fees and expenses associated with an
     investment in variable insurance products offered by Security Benefit Life
     Insurance Company. If returns had taken into account these fees and
     expenses, performance would have been lower. Shares of a Series of SBL Fund
     are available only through the purchase of such products.

     The performance data quoted above represents past performance. Past
     performance is not predictive of future performance. The 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.

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 13.51%.

(2)  Expenses are equal to the Series annualized expense ratio 1.00% multiplied
     by the average account value over the period, multiplied by 184/365 (to
     reflect the one-half year period).

TO OUR SHAREHOLDERS:

With a strong second half of the year, Series Z of SBL Fund - Alpha Opportunity
Series, returned 6.66% for the 12-month period ended December 31, 2005,
outpacing the Series' median peer group return of 5.45%, and the 4.91% return
for the S&P 500 Total Return Index for the same timeframe. We believe our
investment approach delivers significant long-term value, as demonstrated by the
Series' total return of 42.07% since its July 7, 2003 inception, which has
exceeded the S&P 500's Total Return by 15.18%.

During the year, the active investing strategy of the Series exceeded the Index,
and the passive investing strategy performed as expected. The passive strategy
replicates the Index by investing in high-quality, short-term fixed income
instruments and by being long in index futures. While the passive strategy
provides the necessary liquidity, the active strategy focuses on adding value
long term.

Through an actively managed portfolio of mainly common stocks, both long and
short, we are investors focused on generating positive (absolute) returns over
time during various market environments while maintaining a risk profile that is
less than the marketplace in general. We are sensitive to changes in stock
prices and company and market information. This proactive approach helps keep
our investment themes fresh and risk level moderate.

TOP PERFORMERS IN WORLDWIDE INFRASTRUCTURE BUILDING

For the year 2005, the Series' most successful holdings were in the basic
materials, energy, engineering and industrial machinery sectors, all of which
benefited from worldwide infrastructure building, particularly in China. These
included Phelps Dodge Corporation, Joy Global Inc., Fluor Corporation, Arch
Coal, Inc., and Bucyrus International, Inc. There were company specific
disappointments, however. Texas Industries, Inc., Braskem S.A. and Avery
Dennison Corporation experienced earnings shortfalls and therefore were
underperformers.

As of year-end, the active portion of our portfolio was composed of
approximately 87% long equities and the balance in cash. Individual holdings
remain broadly diversified with sector concentrations in materials and
processing, producer durables and selected transports. The Series' holdings at
year-end included Weyerhaeuser Company, Caterpillar Inc., Eagle Materials, Inc.,
Southwest Airlines Company, Cascade Corporation, Arch Coal, Inc. and CNF, Inc.


OUTLOOK FOR 2006

We see opportunity ahead. Our investment approach remains intact. Our investment
process principally screens for trend, value and theme. The vast majority of
stocks are trending positively. Currently equities offer attractive value over
bonds, real estate and most other assets. We continue to be focused on the best
relative -value sectors which include the materials, energy and production
segments of the economy. Cyclicals look attractive relative to non-cyclicals.

In selected sectors, we believe a strong market rally may unfold. Investors
continue to have generally low expectations for equities and are both absolutely
and relatively underinvested in the market. Our "post boom/bust" investment
theme remains in clear focus and we expect to see a solid market rally led by
energy, materials, industrials and transportation.

We appreciate your commitment and investment in the Series and look forward to
continuing our service in 2006.

Sincerely,


Bill Jenkins, Co-Portfolio Manager
Mark Lamb, Co-Portfolio Manager

PERFORMANCE

INFORMATION ABOUT YOUR SERIES EXPENSES

CALCULATING YOUR ONGOING SERIES EXPENSES

EXAMPLE

As a shareholder of the Series, you incur ongoing costs, including management
fees and other series expenses. Performance figures and expense ratios do not
reflect fees and expenses associated with an investment in variable insurance
products. Shares of a Series of SBL Fund are available only through the purchase
of such products. This example is intended to help you understand your ongoing
costs (in dollars) of investing in the Series and to compare these costs with
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 invested at the beginning of the period and held for the
entire period, July 1, 2005 - December 31, 2005.

ACTUAL EXPENSES

The first line in the table provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table provides information about hypothetical account
values and hypothetical expenses based on the Series actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Series
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Series and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any fees and expenses associated with an
investment in variable insurance products. Therefore, the second line is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these fees and expenses
associated with an investment in variable insurance products were included, your
costs would have been higher.

(1)  The actual ending account value is based on the actual total return of the
     Series for the period July 1, 2005 to December 31, 2005 after actual
     expenses and will differ from the hypothetical ending account value which
     is based on the Series expense ratio and a hypothetical annual return of 5%
     before expenses. The actual cumulative return at net asset value for the
     period July 1, 2005 to December 31, 2005 was 7.96%.

(2)  Expenses are equal to the Series annualized expense ratio 2.51% multiplied
     by the average account value over the period, multiplied by 184/365 (to
     reflect the one-half year period).

Notes to Financial Statements
December 31, 2005

1.SIGNIFICANT ACCOUNTING POLICIES

     SBL Fund (The Fund) is registered under the Investment Company Act of 1940,
as amended, as an open-end management investment company of the series type.
Each series, in effect, represents a separate fund. The Fund is required to
account for the assets of each series separately and to allocate general
liabilities of the Fund to each series based on the net asset value of each
series. Shares of the Fund will be sold only to separate accounts of Security
Benefit Life Insurance Company (SBL). The following is a summary of the
significant accounting policies followed by the Fund in the preparation of its
financial statements.

     A. SECURITY VALUATION - Valuations of the Fund's securities are supplied by
pricing services approved by the Board of Directors. The Fund's officers, under
the general supervision of the Board of Directors, regularly review procedures
used by, and valuations provided by, the pricing services. Each security owned
by a Fund that is listed on a securities exchange is valued at its last sale
price on that exchange on the date as of which assets are valued. Where the
security is listed on more than one exchange, the Fund will use the price of
that exchange that it generally considers to be the principal exchange on which
the stock is traded. Securities listed on the Nasdaq Stock Market, Inc.
("Nasdaq") will be valued at the Nasdaq Official Closing 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 Fund's
investment manager, then the securities are valued in good faith by such method
as the Board of Directors determines will reflect the fair value. If events
occur after the close of the foreign exchange that will affect the value of a
fund's portfolio securities before the time as of which the NAV is calculated (a
"significant event"), the security will generally be priced using a fair value
procedure. If the Valuation Committee determines a significant event has
occurred, it will evaluate the impact of that event on an affected security or
securities, to determine whether a fair value adjustment would materially affect
the Fund's net asset value per share. Some of the factors which may be
considered by the Board of Directors in determining fair value are fundamental
analytical data relating to the investment; the nature and duration of any
restrictions on disposition; trading in similar securities of the same issuer or
comparable companies; information from broker-dealers; and an evaluation of the
forces that influence the market in which the securities are purchased and sold.
The Fund generally will value short-term debt securities at prices based on
market quotations for such securities or securities of similar type, yield,
quality and duration, except those securities purchased with 60 days or less to
maturity are valued on the basis of amortized cost which approximates market
value.

     Generally, trading in foreign securities markets is substantially completed
each day at various times prior to the close of the New York Stock Exchange. The
values of foreign securities are determined as of the close of such foreign
markets or the close of the New York Stock Exchange, if earlier. All investments
quoted in foreign currency are valued in U.S. dollars on the basis of the
foreign currency exchange rates prevailing at the close of business. Investments
in foreign securities may involve risks not present in domestic investments. The
Valuation Committee will determine the current value of such foreign securities
by taking into consideration certain factors which may include those discussed
above, as well as the following factors, among others: the value of the
securities traded on other foreign markets, ADR trading, closed-end fund
trading, foreign currency exchange activity, and the trading prices of financial
products that are tied to foreign securities such as WEBS(R). In addition, the
Board of Directors has authorized the Valuation Committee and Administrator to
use prices and other information supplied by Interactive Data Corporation's Fair
Value Information Service in valuing foreign securities. Since foreign
securities may be denominated in a foreign currency and involve settlement and
pay interest or dividends in foreign currencies, changes in the relationship of
these foreign currencies to the U.S. dollar can significantly affect the value
of the investments and earnings of the Fund. Foreign investments may also
subject the Series to foreign government exchange restrictions, expropriation,
taxation or other political, social or economic developments, all of which could
affect the market value and/or credit risk of the investments.

     B. REPURCHASE AGREEMENTS - In connection with transactions in repurchase
agreements, it is the Fund's policy that its custodian take possession of the
underlying collateral and that the fair value of the collateral exceed the
principal amount of the repurchase transaction, including accrued interest, at
all times. If the seller defaults, and the fair value of the collateral
declines, realization of the collateral by the Funds may be delayed or limited.

     C. FOREIGN CURRENCY TRANSACTIONS- The accounting records of the Fund are
maintained in U.S. dollars. All assets and liabilities initially expressed in
foreign currencies are converted into U.S. dollars at prevailing exchange rates.
Purchases and sales of investment securities, dividend and interest income, and
certain expenses are translated at the rates of exchange prevailing on the
respective dates of such transactions.

     The Fund does not isolate that portion of the results of operations
resulting from changes in the foreign exchange rates on investments from the
fluctuations arising from changes in the market prices of securities held. Such
fluctuations are included with the net realized and unrealized gain or loss on
investments.

     Net realized foreign exchange gains and losses arise from sales of
portfolio securities, sales of foreign currencies, and the difference between
asset and liability amounts initially stated in foreign currencies and the U.S.
dollar value of the amounts actually received or paid. Net unrealized foreign
exchange gains or losses arise from changes in the value of other assets and
liabilities at the end of the reporting period, resulting from changes in the
exchange rates.

     D. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS - The Fund may enter into
forward foreign exchange contracts in order to manage foreign currency risk from
purchase or sale of securities denominated in foreign currency. A series may
also enter into such contracts to manage the effect of changes in


                                      190



Notes to Financial Statements
December 31, 2005

foreign currency exchange rates on portfolio positions. These contracts are
marked to market daily, by recognizing the difference between the contract
exchange rate and the current market rate as unrealized gains or losses.
Realized gains or losses are recognized when contracts are settled and are
reflected in the Statement of Operations. These contracts involve market risk in
excess of the amount reflected in the Statement of Assets and Liabilities. The
face or contract amount in U.S. dollars reflects the total exposure these funds
have in that particular currency contract. Losses may arise due to changes in
the value of the foreign currency or if the counterparty does not perform under
the contract.

     E. FUTURES - The Fund may utilize futures contracts to a limited extent,
with the objectives of maintaining full exposure to the underlying stock market,
enhancing returns, maintaining liquidity, minimizing transaction costs and
hedging possible variations in foreign exchange rates. The Fund may purchase or
sell financial and foreign currency futures contracts to immediately position
incoming cash in the market, thereby simulating a fully invested position in the
underlying index while maintaining a cash balance for liquidity. In the event of
redemptions, the series may pay from its cash balances and reduce its future
positions accordingly. Returns may be enhanced by purchasing futures contracts
instead of the underlying securities when futures are believed to be priced more
attractively than the underlying securities. The primary risks associated with
the use of futures contracts are imperfect correlation between changes in market
values of stocks contained in the indexes and the prices of futures contracts,
and the possibility of an illiquid market. Futures contracts are valued based
upon their quoted daily settlement prices. Upon entering into a futures
contract, the series are required to deposit and maintain as collateral either
cash or securities, representing the initial margin, equal to a certain
percentage of the contract value. Cash deposits are shown as restricted cash on
the Statement of Assets and Liabilities; securities held as collateral are noted
in the Schedule of Investments. Subsequent changes in the value of the contract
are recorded as unrealized gains or losses. The variation margin is paid or
received in cash daily by the series. The series realizes a gain or loss when
the contract is closed or expires.

     F. OPTIONS WRITTEN - The Fund 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 (and the writer the
obligation to sell or purchase), respectively, a security at a specified price,
until a certain date. Options may be used to hedge the series portfolio, to
increase returns or to maintain exposure to the equity markets. 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
counterparty 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.

     G. SECURITY TRANSACTIONS AND INVESTMENT INCOME - Security transactions are
accounted for on the date the securities are purchased or sold (trade date).
Realized gains and losses are reported on an identified cost basis. Dividend
income is accrued as of the ex-dividend date, except that certain dividends for
foreign securities where the ex-dividend date may have passed are recorded as
soon as the fund is informed of the dividend in the exercise of reasonable
diligence. Interest income is recognized on the accrual basis including the
amortization of premiums and accretion of discounts on debt securities.

     H. EXPENSES - Expenses that are directly related to one of the series are
charged directly to that series. Other operating expenses are allocated to the
series on the basis of relative net assets within the Fund.

     I. 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.

     J. TAXES - The Fund intends to comply with the requirements of the Internal
Revenue Code applicable to regulated investment companies and distribute all of
its taxable net income and net realized gains sufficient to relieve it from all,
or substantially all, federal income, excise and state income taxes. Therefore,
no provision for federal or state income tax is required.

     K. EARNINGS CREDITS - Under the fee schedule with the custodian, the Fund
may 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 are before the reduction in expense from the related
earnings credits.

     L. USE OF ESTIMATES - The preparation of financial statements in conformity
with U.S. 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 increases and decreases in
net assets from operations during the reporting period. Actual results could
differ from those estimates.

     M. SHORT SALES - Certain of the series may make short sales "against the
box," in which the series enters into a short sale of a security it owns. At no
time will more than 15% of the value of the series' net assets be in deposits on
short sales against the box. In a short sale that is not "against the box," a
series sells a security which it does not own, in anticipation of a decline in
the market value of the security. To complete the sale, the series must borrow
the security generally from the broker through which the short sale is made in
order to make delivery to the buyer. The series must replace the security
borrowed by purchasing it at the market price at the time of replacement. The
series is said to have a "short position" in


                                      191



Notes to Financial Statements
December 31, 2005

securities sold until it delivers them to the broker. 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, but not yet purchased, may require purchasing the securities at prices
which differ from the market value reflected on the Statement of Assets and
Liabilities. The series are liable for any dividends or interest payable on
securities while those securities are in a short position. As collateral for its
short positions, the series are required under the Investment Company Act of
1940 to maintain segregated assets consisting of cash, cash equivalents or
liquid securities. These segregated assets are valued consistent with Note 1A
above. These segregated assets are required to be adjusted daily to reflect
changes in the market value of the securities sold short.

     N. INDEMNIFICATIONS - Under the Fund's organizational documents, its
Officers and Directors are indemnified against certain liabilities arising out
of the performance of their duties to the Fund. In addition, in the normal
course of business, the Fund enters into contracts that provide general
indemnification to other parties. The Fund's maximum exposure under these
arrangements is unknown as this would involve future claims that may be made
against the Fund that have not yet occurred, and may not occur. However, the
Fund has not had prior claims or losses pursuant to these contracts and expects
the risk of loss to be remote.

2. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

     Management fees are paid monthly to Security Management Company, LLC (SMC),
based on the following annual rates:

*    Series Z's management fee will range from 1.25% to 2.75% of aver- age daily
     net assets as discussed below.

(1)  SMC receives a management fee from Series Z that consists of two
     components. The first component is an annual base fee equal to 2.00% of
     Series Z's average daily net assets. The second component is a base fee
     adjustment that either increases or decreases the base fee, depending upon
     how Series Z performed relative to the S&P 500 Index over the prior
     12-month period (the "Measuring Period"). SMC will receive the base fee of
     2.00% without adjustment if the performance of Series Z matches the
     performance of the S&P 500 Index. The maximum base fee adjustment at each
     calculation period is equal to 1/12th of 0.75% up or down in the event that
     Series Z outperforms or underperforms the S&P 500 Index by 15% or more. SMC
     calculates the base fee adjustment each month based upon Series Z's
     performance relative to the S&P 500 Index during the Performance Period
     ending on the last day of the month. If Series Z outperforms the S&P 500
     Index over the Measuring Period, the base fee is adjusted upward. The
     monthly upward adjustment is equal to the amount by which Series Z's
     performance exceeds that of the S&P 500 Index divided by 15 and multiplied
     by the average daily net assets of Series Z during the Measuring Period to
     determine the base fee adjustment for the month. If Series Z underperforms
     the Index, the base fee is adjusted downward on the same basis. SMC will
     determine the dollar amount of any performance adjustment each month by
     multiplying the adjustment percentage by the average daily net assets of
     Series Z during the Measuring Period and dividing by the number of days in
     the Measuring Period and then multiplying that amount by the number of days
     in the current month.

(2)  Prior to June 30, 2005, management fees were payable to SMC at an annual
     rate of 0.75% of the average daily net assets. Effective June 30, 2005,
     management fees were payable at an annual rate of 0.65% of the average
     daily net assets.

     SMC also acts as the administrative agent and transfer agent for the Fund,
and as such performs administrative functions, transfer agency and dividend
disbursing services, and the bookkeeping, accounting and pricing functions for
each series. At a meeting held on November 18, 2005, the Board of Directors
approved a new administrative fee schedule. This new fee schedule was effective

*    The minimum annual charge for administrative fees is $25,000 for each
     series.

     SMC is paid the following for providing transfer agent services to the
Fund:


                             
Annual charge per account       $5.00 - $8.00

Certain out-of-pocket charges       Varies


     The investment advisory contract between the Fund and SMC provides that the
total annual expenses of each series (including management fees, but excluding
interest, taxes, brokerage commissions and extraordinary expenses) will not
exceed the level of expenses which the series is permitted to bear under the
most restrictive expense limitation imposed by any state in which shares of the
Fund are then offered for sale. For the year ended December 31, 2005, SMC agreed
to limit the total expenses for Series P, V and X to an annual rate of 2% of the
average daily net asset value of each respective series, and limit Series G, H,
Q, W and Y to an annual rate of 1.75%. SMC has agreed to limit the total other
expenses for Series Z to 0.50%.

     At December 31, 2005, Security Benefit Life Insurance Company, through
their insurance company separate accounts, owned 100% of the outstanding shares
of the Fund and the respective series.

7. FEDERAL TAX MATTERS

     Net investment income and net realized gains (losses) may differ for
financial statement and tax purposes because of temporary or permanent book/tax
differences. These differences are primarily due to interest income accrued for
defaulted and variable rate securities for tax purposes, differing book and tax
amortization methods for premium and market discount, consent dividends,
ordinary net operating losses and the expiration of capital loss carryovers. To
the extent these differences are permanent differences, adjustments are made to
the appropriate equity accounts in the period that the differences arise. The
following adjustments were made to the Statement of Assets and Liabilities to
reflect permanent differences:

sales, the realization for tax purposes of unrealized gains on certain forward
foreign currency contracts, passive foreign investment companies and certain
appreciated securities at January 1, 2001.

Report of Independent Registered Public Accounting Firm

TO THE CONTRACTHOLDERS AND BOARD OF DIRECTORS
SBL FUND

We have audited the accompanying statements of assets and liabilities, including
the schedules of investments, of SBL Fund (comprised of Series A, B, C, D, E, G,
H, J, N, O, P, Q, S, V, W, X, Y and Z portfolios) (the Fund), as of December 31,
2005, and the related statements of operations for the year then ended, the
statement of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the periods indicated therein.
These financial statements and financial highlights are the responsibility of
the Fund's 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 the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion of the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
investments owned as of December 31, 2005, by correspondence with custodians and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. 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 each
of the respective portfolios constituting the Fund at December 31, 2005, the
results of their operations for the year then ended, the changes in their net
assets for each of the two years in the period then ended, and the financial
highlights for each of the periods indicated therein, in conformity with U.S.
generally accepted accounting principles.

                                                               ERNST & YOUNG LLP

Directors' Disclosure
(unaudited)

DIRECTOR APPROVAL OF INVESTMENT ADVISORY AGREEMENT

     At an in-person meeting of the Fund's Boards of Directors held on November
17-18, 2005, called for the purpose of, among other things, voting on the
renewal of the investment advisory and sub-advisory agreements applicable to the
Fund, the Fund's Board of Directors, including the Independent Directors,
unanimously approved the continuation for a one-year period of the investment
advisory agreement between the Fund and Security Management Company, LLC
("SMC"), as well as each investment sub-advisory agreement applicable to the
Fund. In reaching this conclusion, the Directors requested and obtained from SMC
and each investment sub-adviser such information as the Directors deemed
reasonably necessary to evaluate the proposed renewal of the agreements. The
Fund's Board of Directors carefully evaluated this information, and was advised
by legal counsel with respect to its deliberations.

     In considering the proposed continuation of the investment advisory and
sub-advisory agreements, the Independent Directors evaluated a number of
considerations, including, among others, (1) the nature, extent, and quality of
the advisory services to be provided by SMC and the investment sub-advisers; (2)
the investment performance of the Fund, SMC and the various investment
sub-advisers; (3) the costs of the services to be provided and profits to be
realized by SMC and its affiliates from the relationship with the Fund; (4) the
extent to which economies of scale would be realized as the Fund grows; and (5)
whether advisory and sub-advisory fee levels reflect these economies of scale
for the benefit of Fund investors. Each Board of Directors also took into
account other considerations that it believed, in light of the legal advice
furnished to the Independent Directors by their independent legal counsel and
the Directors' own business judgment, to be relevant. Following its review, the
Fund's Board of Directors determined that the investment advisory agreement and
each investment sub-advisory agreement applicable to the Fund (if any) will
enable Fund shareholders to obtain high quality services at a cost that is
appropriate, reasonable, and in the best interests of shareholders. Accordingly,
the Directors, including the Independent Directors, unanimously approved the
renewal of the investment advisory and investment sub-advisory agreements based
upon the following considerations, among others:

     -    THE NATURE, EXTENT AND QUALITY OF THE ADVISORY SERVICES TO BE
          PROVIDED. The Board of Directors concluded that SMC and the investment
          sub-advisers retained to provide portfolio management services with
          respect to the Fund are capable of providing high quality services to
          the Fund, as indicated by the nature and quality of services provided
          in the past, SMC's management capabilities demonstrated with respect
          to the Fund and other mutual funds managed by SMC, the professional
          qualifications and experience of SMC's and the various sub-advisers'
          portfolio managers, and SMC's investment and management oversight
          processes. The Directors also determined that SMC and the sub-advisers
          proposed to provide investment and related services that were of the
          same quality and quantity as services provided to the Fund in the
          past, and that these services are appropriate in scope and extent in
          light of the Fund's operations, the competitive landscape of the
          investment company business and investor needs.

     -    THE INVESTMENT PERFORMANCE OF THE FUND. With respect to the Fund, the
          Directors concluded on the basis of information supplied by Lipper
          that SMC and the investment sub-advisers had achieved investment
          performance that was acceptable, and competitive or superior relative
          to comparable funds over trailing periods. On the basis of the
          Directors' assessment of the nature, extent and quality of advisory
          services to be provided or procured by SMC, the Directors concluded
          that SMC is capable of generating a level of long-term investment
          performance that is appropriate in light of the Fund's investment
          objectives, policies and strategies and competitive with many other
          investment companies.

     -    THE COST OF ADVISORY SERVICES PROVIDED AND THE LEVEL OF PROFITABILITY.
          On the basis of each Board's review of the fees to be charged by SMC
          for investment advisory and other services, and the estimated
          profitability of SMC's relationship with the Fund, each Board
          concluded that the level of investment advisory fees and SMC's
          profitability are appropriate in light of the management fees and
          overall expense ratios of comparable investment companies and the
          anticipated profitability of the relationship between the Fund and SMC
          and its affiliates. On the basis of comparative information supplied
          by Lipper the Directors determined that the advisory fees and
          estimated overall expense ratio of the Fund are consistent with, and
          often below, industry medians, particularly with respect to mutual
          funds of comparable size. With respect to the Series Z (Alpha
          Opportunity Series), the Directors noted that the Series had a strong
          performance record year to date, which helped to compensate for Series
          Z's higher than average expense ratio. Further, the Directors noted
          that the Series Z's investment advisory fee and expense ratio were
          above median due, at least in part, to its strong performance relative
          to its benchmark index, which increased the advisory fee payable under
          that Fund's "fulcrum" advisory fee arrangement.

     -    WHETHER THE ADVISORY FEES REFLECT ECONOMIES OF SCALE. The Directors
          concluded that the Fund's investment advisory fees appropriately
          reflect the current economic environment for SMC and the competitive
          nature of the mutual fund market. The Directors further determined
          that the Fund has yet to achieve meaningful economies of scale, which,
          therefore, cannot be reflected in the investment advisory fees.

     -    THE EXTENT TO WHICH ECONOMIES OF SCALE WILL BE REALIZED AS THE FUND
          GROWS. While the Fund's investment advisory fees do not reduce should
          Fund assets grow


                                       204



Directors' Disclosure
(unaudited)

          meaningfully, the Directors determined that the investment advisory
          fees payable by the Fund other than Series Z (Alpha Opportunity
          Series) (whose investment advisory fee varies depending on that Fund's
          performance relative to its benchmark index) already reflect potential
          future economies of scale to some extent by virtue of their
          competitive levels (determined with reference to industry standards as
          reported by Lipper and SMC's estimated profitability at current or
          foreseeable asset levels. The Directors also considered that they will
          have the opportunity to periodically reexamine whether a Fund has
          achieved economies of scale, and the appropriateness of investment
          advisory fees payable to SMC and fees payable by SMC to the investment
          sub-advisers, in the future.

     -    BENEFITS (SUCH AS SOFT DOLLARS) TO SMC FROM ITS RELATIONSHIP WITH THE
          FUND (AND ANY CORRESPONDING BENEFITS TO THE FUND). The Directors
          concluded that other benefits described by SMC and the investment
          sub-advisers from their relationships with the Fund, including "soft
          dollar" benefits in connection with Fund brokerage transactions, are
          reasonable and fair, and consistent with industry practice and the
          best interests of the Fund and their shareholders. In addition, the
          Directors determined that the administration, transfer agency and fund
          accounting fees paid by the Fund to SMC are reasonable, fair and in
          the best interests of Fund shareholders in light of the nature and
          quality of the services provided, the associated costs, and the
          necessity of the services for the Fund's operations.

     -    OTHER CONSIDERATIONS: In approving the investment advisory and
          sub-advisory agreements, the Directors determined that SMC has made a
          substantial commitment to the recruitment and retention of high
          quality personnel, and maintains the financial, compliance and
          operational resources reasonably necessary to manage the Fund in a
          professional manner that is consistent with the best interests of the
          Fund and their shareholders. In this regard, the Directors favorably
          considered the compliance track record of the Fund and SMC. The
          Directors also concluded that SMC has made a significant
          entrepreneurial commitment to the management and success of the Fund,
          which entails a substantial financial and professional commitment,
          including investment advisory fee waivers and expense limitation
          arrangements with respect to the Fund to the benefit of Fund
          shareholders.

ITEM 4.       PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a)    Audit Fees. The aggregate fees billed for each of the last two fiscal
       years (the "Reporting Periods") for professional services rendered by the
       Registrant's principal accountant (the "Auditor") for the audit of the
       Registrant's annual financial statements, or services that are normally
       provided by the Auditor in connection with the statutory and regulatory
       filings or engagements for the Reporting Periods, were $303,000 in 2004
       and $327,000 in 2005.

(b)    Audit-Related Fees. The aggregate fees billed in the Reporting Periods

       $5,000 in 2004 and $5,000 in 2005. These services consisted of a review
       of the Registrant's semi-annual financial statements.

       The aggregate fees billed in the Reporting Periods for assurance and
       related services by the Auditor to the Registrant's investment adviser
       (not including any sub-investment adviser whose role is primarily
       portfolio management and is subcontracted with or overseen by another
       investment adviser), and any entity controlling, controlled by or under

       the Audit Committee were $18,000 in 2004 and $17,000 in 2005, which
       related to the review of the transfer agent function.(1)

       ----------
       (1)Prior to May 6, 2003, the Registrant's Audit Committee was not
          required to pre-approve non-audit services. Therefore, the information
          here represents only fees for pre-approved non-audit services rendered
          after May 6, 2003, to Service Affiliates.

(c)    Tax Fees. The aggregate fees billed to the Registrant in the Reporting
       Periods for professional services rendered by the Auditor for tax
       compliance, tax advice and tax planning ("Tax Services") were $47,000 in

       U.S. federal, state and local tax planning, advice and assistance
       regarding statutory, regulatory or administrative developments, (iii) tax

       Audit Committee were $0 in 2004 and $0 in 2005.(2)

       ----------
       (2)Prior to May 6, 2003, the Registrant's Audit Committee was not
          required to pre-approve Tax Services. Therefore, the information here

          6, 2003, to Service Affiliates.

(d)    All Other Fees. The aggregate fees billed to the Registrant in the

       other than the services reported in paragraphs (a) through (c) of this
       Item, were $0 in 2004 and $0 in 2005.

       The aggregate fees billed in the Reporting Periods for Non-Audit Services

       ----------
       (3)Prior to May 6, 2003, the Registrant's Audit Committee was not
          required to pre-approve these services. Therefore, the information

(e)    (1)  Audit Committee Pre-Approval Policies and Procedures. The

            for pre-approval of the auditor's engagements for audit and
            non-audit services to the Registrant. Pre-approval considerations
            include whether the proposed services are compatible with
            maintaining the auditor's independence as specified in applicable
            rules.

(e)    (2)  Percentage of Non-Audit Services Approved under (c)(7)(i)(C). The

       information relating to the provision of non-audit services by E&Y to the
       Registrant (and its affiliates) that were not pre-approved by the Audit
       Committee so that a determination could be made whether the provision of
