Portfolio Manager

To Our Shareholders:

Series A of the SBL Fund - Equity Series returned 12.89% during the year, lagging the benchmark S&P 500 Index’s return of 15.79% and the Series’ peer group median return of 13.92%. Over the last few years, higher beta, smaller capitalization companies have helped drive equity markets higher. In such environments, we tend to under perform. We still believe the market is not yet recognizing the potential in several high quality large capitalization companies. Our performance has been disappointing and we feel not indicative of our potential. We are focused on improving your Series’ returns by upgrading the talent on our equity research team and strengthening our research process. We believe that our approach will deliver good performance over a long-term investment horizon.

Our investment philosophy is centered around three key tenants: First, good investments are purchased at less than their intrinsic value; second, a long-term approach and patience are critical to successful investing; and lastly, we concentrate our investments in companies that have the greatest return potential.

Our process is a bottom-up research driven investment process that attempts to identify companies that have a competitive advantage or have the ability to become more competitive in the future. We focus on owning these companies for three to five years or longer which we believe differentiates us from a majority of our peers and ultimately allows us to make better investment decisions. We buy these companies when their current price trades below their intrinsic value. We closely monitor each company’s progress. We will sell a company if the valuation no longer makes sense, we’ve made a mistake, our investment thesis is no longer valid, or we have a more attractive investment alternative. For this Series, we apply the approach to a broad range of both growth and value names.

Financial, Technology, and Industrial Stocks Top Performers

The Series’ financial holdings were up 35% compared to 19% for the Index. This was driven almost entirely by our position in First Marblehead Corporation, up over 150%. Ill-placed short-term concerns over the company’s competitive position offered a great buying opportunity for a leading student lender with a significant competitive advantage as a result of their loan under writing capability, superior economics, and additional value-added services.

The technology sector was up over 17% versus the comparable sector Index return of 9%. The largest contributor was Unisys Corporation, up 34%. The company benefited from improving its competitive position by lowering costs and improving business execution. Not owning Intel, down 17% and Yahoo, down 34%, helped the Series as well. While both are good companies, the valuations did not meet our criteria for an attractive risk/reward profile.

General Dynamics Corporation in the industrial sector was up 32%, with the company benefiting from strong results in its defense related segment and corporate aircraft segment.

Energy and Telecom Disappointing

Energy overall negatively impacted the Series. In the Series the sector was up just over 6% versus up 24% for the energy sector return within the Index. This was driven in part by Evergreen Energy, Inc., down over 42% (previously known as KFx), and Halliburton Company, up only 1%. Evergreen Energy was hurt by concerns over the viability of the initial production results of its proprietary clean coal technology. Halliburton was impacted more generally by the recent exodus from oil services related names as a result of a weakening energy commodity market.

The telecom sector in the benchmark was up over 36%, while our sector return was down 11%. Not owning AT&T, up 53%, and Bell South, up 80%, negatively impacted the Series. It appears the market is more confident in the newly-merged telecom players. We've avoided these names because we believe it’s very difficult to determine which, if any, company will be able to create a lasting competitive advantage that allows them to generate acceptable returns on the significant capital expenditures required to build out their services offerings. Our position in Sprint Nextel Corporation, down 10%, hurt the Series’ performance. Concerns over how the integration of Nextel was progressing and lack of improvement in its core legacy Sprint operations contributed to the weakness. We still believe in management’s ability to show steady improvement as demonstrated by the spinoff of its slower growing wireline business.

2007 Market Outlook

The current low return investment environment that exists outside of equities has continued to make available ample liquidity in the U.S. equity market. Falling energy prices have helped increase consumer confidence and provide support to corporate profit margins through lower raw material input prices. Additionally, businesses have very healthy balance sheets to help drive future growth initiatives.


		Series A
Manager’s Commentary		(Equity Series)
February 15, 2007		(unaudited)

As we noted in last year’s shareholder letter, we’ve been concerned about a slowdown in U.S. consumer spending for some time. This concern has yet to materialize, but we still think it will happen. Lower energy prices will help, however, higher interest rates and a housing market slowdown provide likely headwinds. The Federal Reserve is walking a fine line between managing inflation risks while supporting economic growth. We’re unsure, like most in the market, what the Fed’s next move is. This uncertainty will weigh on the markets until it’s resolved.

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 value¹. 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

Series A vs. S&P 500 Index

LOGO

$10,000 Over 10 Years

The chart above assumes a hypothetical $10,000 investment in Series A (Equity Series) on December 31, 1996 and reflects the fees and expenses of Series A. 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.

Average Annual Returns


Periods Ended 12-31-06¹	1 Year		5 Years		10 Years
Series A	12.89	%	3.24	%	4.70	%

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, 2006 - December 31, 2006.

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.

Series Expenses


	Beginning Account Value 07-01-06		Ending Account Value 12-31-06¹		Expenses Paid During Period²


Series A (Equity Series)
Actual	$	1,000.00	$	1,107.60	$	4.83
Hypothetical		1,000.00		1,020.62		4.63

The actual ending account value is based on the actual total return of the Series for the period July 1, 2006 to December 31, 2006 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, 2006 to December 31, 2006 was 10.76%.

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

Portfolio Manager

To Our Shareholders:

Series B of the SBL Fund - Large Cap Value series returned 22.00% during the year, lagging the benchmark Russell 1000 Value Index’s return of 22.25%, but out performing the Series’ peer group median return of 18.86%. Good stock selection was offset slightly by our sector weights in 2006. While being disappointed that our results were below the benchmark, we believe that our approach delivers performance over the long-term.

Our investment philosophy is centered around three key tenants: first, good investments are purchased at less than their intrinsic value; second, a long-term approach and patience are critical to successful investing; and lastly, we concentrate our investments in companies that have the greatest return potential.

Our process is a bottom-up research driven investment process that attempts to identify companies that have the ability to become more competitive in the future. We focus on owning these companies for three to five years or longer which we believe differentiates us from a majority of our peers and ultimately allows us to make better investment decisions. We buy these companies when their current price trades below their intrinsic value. We closely monitor each company’s progress. We will sell a company if the valuation no longer makes sense, we’ve made a mistake and our investment thesis is no longer valid, or we have a more attractive investment alternative. For this Series, we apply this philosophy to a broad range of value names.

Financials and Industrial Stocks Top Performers

The Series’ Financial holdings were up 37% compared to 20% for the Index. This was driven almost entirely by our position in First Marblehead Corporation, up over 150%. Ill-placed short-term concerns over the company’s competitive position offered a great buying opportunity for a leading student lender with a significant competitive advantage as a result of their loan underwriting capability, superior economics, and additional value-added services.

Holdings International, Inc., the industrial sector were up 28%. McDermott appreciated 71%, driven by strong demand for its energy infrastructure construction related services. Hughes Supply was up 27% as it agreed to be acquired by Home Depot, Inc. Hughes’ strong position in the professional contractor market fits well into Home Depot’s expansion plans in that segment.

Telecom and Energy Disappointing

The telecom sector in the benchmark was up over 39%, while our sector return was up just 1%. Not owning AT&T, up 53%, and Bell South, up 80%, negatively impacted the Series. It appears the market is more confident in the newly-merged telecom players. We’ve avoided these names because we believe it’s very difficult to determine which, if any, company will be able to create a lasting competitive advantage that allows them to generate acceptable returns on the significant capital expenditures required to build out their services offerings. Our position in Sprint Nextel Corporation, down 10%, hurt the Series’ performance. Concerns over how the integration of Nextel was progressing and lack of improvement in its core legacy Sprint operations contributed to the weakness. We still believe in management’s ability to show steady improvement as demonstrated by the spinoff of its slower growing wireline business.

Poor stock selection in the energy sector negatively impacted the Series as the sector underperformed the value index. Specifically, Halliburton Company, up just 1%, and an underweight position in Exxon Mobil Corporation, up 39%, had the largest negative impact. Halliburton was impacted more generally by the recent exodus from oil services related names as a result of a weakening energy commodity market. Exxon outperformed formed the diversified group of integrated oil companies we owned.

2007 Market Outlook

As we noted in last year’s shareholder letter, we’ve been concerned about a slowdown in U.S. consumer spending for some time. This concern has yet to materialize, but we still think it will happen. Lower energy prices will help; however, higher interest rates and a housing market slowdown provide likely headwinds. The Federal Reserve is walking a fine line between managing inflation risks while supporting economic growth. We’re unsure, like most in the market, what the Fed’s next move is. This uncertainty will weigh on the markets until it’s resolved.

Sincerely,

Mark A. Mitchell, Portfolio Manager

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, 2006 - December 31, 2006.

Advisor, Security Management Company, LLC

Christi Fletcher

Portfolio Manager

To Our Shareholders:

The first half of 2006 proved to be comparable to 2005. The Federal Reserve Board’s campaign to increase interest rates resulted in four rate increases during the Series’ fiscal year ending at 5.25%. The yield of the Series C of the SBL Fund—Money Market Series rose accordingly, returning 4.43% for the year ended December 31, 2006, which exceeded the benchmark I-Money Net Retail Tier 1 of 4.30% for the same period.

Aside from the increases in short-term interest rates, the continued threat of higher inflation and a flat yield curve the past year proved positive for credit issuers. Companies continued to display solid balance sheet fundamentals, strong cash flows and good profit growth. In addition, the trend continues as firms utilize the excess cash flows for increasing dividends or share repurchases (shareholder friendly), rather than bolstering credit quality.

Characteristics of Portfolio Assets

At December 31, 2006, the average maturity of Series C was 51 days, which was a couple of days longer than the benchmark. This strategy positioned the Series to take advantage of longer dated securities, as the threat of decreasing rates loomed.

The yield curve for money market instruments went from upward trending during the first half of 2006 to relatively flat in the second half. This made for interesting challenges for additional yield along the maturity spectrum and among various types of money market instruments. The majority of the Series assets lie in the corporate debt sector via commercial paper, floating rate securities and Yankee CD’s, due to the strong balance sheet fundamentals of credit and because it represented good value against other sectors. At year end, approximately 52% of the Series was made up of Commercial Paper, 30% in Floating Rate securities (which includes Corporate and U.S. Government-Backed), 7% in U.S. Government/Agency obligations, 7% in Yankee CD’s, 3% in funding agreements, and 1% Mortgage-related products.

Outlook for 2007

In 2006, the economy continued to grow but with strong head winds from the long anticipated correction in the housing market, the Federal Reserve rate increases that started to take effect, and commodity prices yet again hitting all time highs. Looking forward to 2007, the economy will continue to grow but at a slower pace versus recent years. We expect short-term rates to remain at 5.25% for most of 2007. We believe the approach the Federal Reserve will take is one of a wait-and-see attitude. We are not anticipating a cut in short-term rates but have not factored in an increase either, unless we see an increase in inflation. At this point, there is limited evidence of either situation unfolding during 2007.

With a stable U.S. economy predicted in 2007, as fundamentals in the corporate sector remain solid and companies continue to generate strong cash flows and earnings growth, the Series will continue to be invested heavily in the corporate debt sectors within the money market arena.

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,

Christina Fletcher

Portfolio Manager

To Our Shareholders

Series D of the SBL Fund - Global Series returned 17.34% under-performing the benchmark, Morgan Stanley Capital International, Inc. (MSCI) World Index return of 20.07% for the year ended December 31, 2006. Our investment philosophy is based on the idea that earnings growth drives stock prices and that we are most likely to identify long-term earnings growth opportunities by examining trends that provide tailwinds for growth in the coming decade. We are very interested in attributes of industries and companies within those industries that are likely to be beneficiaries of these long-term trends. Ideally, we like to buy these businesses at a bargain price, that is, a price where we have the opportunity to double our investment in three to five years. This rarely happens except when there is a perception that something has gone wrong with an excellent business. If we can determine that the difficulty is temporary rather than permanent, then we consider it to be a good investment.

We had notable successes with a number of our larger holdings, such as Infosys Technologies Ltd., Reckitt Benckiser plc and H&M Hennes & Mauritz AB. However, there were significant underperformers, most notably eBay, Inc., Advanced Micro Devices, Inc. and Boston Scientific Corporation.

Additionally there were other disappointments, including a significant market slowdown in the demand for implantable cardiac defibrillators as well as a deceleration in the growth rate of knee and hip replacements, both of which impacted our holdings. We remain confident that the long-term opportunity for all of the segments that faced setbacks in the past year remains excellent and that our original thesis will come to pass.

Our investments in software companies, Intuit, Inc. and Adobe Systems, Inc., continue to remain positive, as the companies remain innovative with new products that not only impress their existing customer bases but achieve broader appeal. Our investments in Inditex S.A., the owner of Zara stores, and Tesco plc, the UK’s leading grocery chain, have been worthwhile as they continue to grow rapidly worldwide, leveraging their scale and supply chain to achieve high economic returns. Our investments in television companies, Zee Telefilms Ltd. in India, and Grupo Televisa SA in Mexico, contributed positively to the Series’ performance as they continue to retain high market shares in their respective markets and as the appeal of their programming grows worldwide.

We are finding excellent opportunities across a variety of areas particularly in technology. It should be noted that our investment philosophy is based on returns over a three to five year period rather than the next quarter or two. We continue to favor a number of our existing holdings, such as L.M. Ericsson and Juniper Networks, Inc. Additional investments may be made as the opportunity for communication network build-outs remains robust. Additionally, we are finding quality investment opportunities in the areas of analog and mixed signal semiconductors.

Companies such as Maxim Integrated Products, Inc. and Linear Technology Corporation. continue to see high margin profitable growth and are now available at a fraction of their valuations of only a few years ago. Leading companies in the Programmable Logic Devices arena such as Altera Corporation. and Xilinx, Inc., we believe, also provide significant investment upside. We have also invested significantly in companies such as Carnival Corporation. which operates the Carnival Cruise Lines, and the car manufacturer Bayerische Motoren Werke AG (BMW), which we feel has solid franchises. Both are available at bargain prices. Automatic Data Processing, Inc., the leading payroll processor in the world, is another investment we highly favor. Its business opportunities expand as more companies look to outsource more of their non-core activities to high-quality, lower cost providers. As global growth continues to be positive and interest rates remain relatively low, we remain optimistic about markets generally. As such, we expect to continue to see productive opportunities for investment. We remain focused on our long-term investment philosophy that looks for “good companies in good businesses at good prices.”

In closing, please remember that investing in foreign markets entails additional risks, including the risks associated with currency fluctuations and political uncertainties, as described in the prospectus.

Sincerely,

Rajeev Bhaman

To Our Shareholders:

2006 proved to be an interesting year for the fixed income markets. Interest rates across the yield curve increased, with long-term rates increasing less than short-term rates resulting in a more inverted yield curve. The Federal Reserve held the Fed funds’ rate unchanged at the August meeting after 17 consecutive increases, citing moderating economic growth, a slow down in the housing market, and the lagged effects of previous interest rate increases. Inflation still remained above levels preferred by the Fed so for the remainder of the year the market debated whether economic growth would slow down causing an interest rate cut, or inflation would continue to be high and cause another increase. The market also debated the impact of the inverted yield curve, which historically is a good indicator of future economic weakness, as equities and credit spreads continued to generate good performance signaling strong economic growth. Series E of the SBL Fund - Diversified Income Series earned a return of 3.80% for the year ended December 31, 2006, which lagged the benchmark Lehman Brothers Aggregate Index return of 4.33% for the same period.

Factors Affecting Performance in 2006

The returns for the bond market were again impacted by the Federal Reserve Bank’s four interest rate increases in the first half of 2006. As bond interest rates moved up across the yield curve, prices of bonds fell. The yield curve also inverted, with short-term rates higher than long term rates, which historically increases the risk of recession. Treasury securities underperformed the other fixed income sectors due to their lower yield.

During 2006, the Series was positioned shorter than the average maturity of its benchmark to mitigate the impact of rising rates. This strategy was correct and protected the Series from loss due to declining bond prices. The Series was slightly overweighted corporate bonds to take advantage of the strong credit fundamentals and low volatility of corporate spreads. While the corporate overweight was correct, it should have been larger given the strong performance of the sector. We kept the corporate weighting lower due to concerns about valuations and event risk in the sector. Mortgage-backed securities were slightly overweighted to take advantage of the additional yield and low volatility levels. This over weight proved successful as mortgage-backed securities were the top performing sector in the Lehman Aggregate Index. Again, to maximize performance the overweight should have been larger.

The Composition of Portfolio Assets

At the end of the year, the Series held 22% in mortgage backed securities, 2% in asset-backed and commercial mortgage-backed securities, 31% in corporate issues, 43% in U.S. Treasury and Government agencies, and 2% in cash. This portfolio composition is over weighted corporate bonds and mortgage-backed securities and underweighted in Treasury and Agency issues relative to the benchmark.

Outlook for 2007

In 2006 the economy continued to grow but with strong head winds from the long anticipated correction in the housing market, the Federal Reserves rate increases starting to take effect, and commodity prices hitting all time highs. Looking for ward to 2007 the economy should continue to grow but at a slower rate than the recent past. One of the main concerns widely discussed in 2006 was the slowdown in the housing market. The housing slowdown had a negative impact on economic growth in 2006, but it does not appear to be enough to push the economy into a recession with unemployment near all time lows and wage inflation still relatively high. The strong labor market should also drive consumer spending to continue growing at a reasonable rate. Commodity prices also declined in late 2006, which should add some positive stimulus to the economy and lower inflation expectations.

The yield curve remains flat or inverted which traditionally has been a sign of future economic weakness. In the current environment we believe that the strong demand for long U.S. Treasury securities from global investors and investors searching to match long liabilities has largely contributed to this situation rather than a pending recession.

We expect short term rates to remain at 5.25% for most of 2007. We believe the Fed has paused and will remain paused with a wait-and-see attitude. We believe it won’t raise rates because there’s no compelling reason to do so. On the other hand, we believe it won’t cut rates either. For the Fed to raise rates again, inflation would have to increase while the economy remained strong. For the Fed to cut rates, inflation would have to decline into its preferred range and economic growth would have to slow down. At this point, there is limited evidence of either situation. Also, due to the increasing amounts of leverage in the capital markets we believe cutting rates

will also send an unwarranted bullish signal to the credit and equity markets. Our bias will be to position the portfolio short of the average maturity of the benchmark because the market is pricing in a higher probability of a Fed rate decrease than we believe will occur.

With a stable and growing economy predicted in 2007, the Series will be overweighted corporate bonds for their additional yield. Fundamentals in the corporate sector remain strong as companies generate strong cash flow and profit growth. The primary short-term risk in corporate bonds is increased share repurchases and leveraged buyouts, which negatively impact credit quality. Our focus will continue to be on companies and sectors where this activity has a low probability.

Our primary concern for 2007 is that most risk assets are priced at high valuations and the economy is entering the fifth year of an expansion. We find ourselves constantly asking when the wind will blow the other direction with the economy slowing and credit spreads widening. At this point the evidence tells us to continue to own the additional yield these assets provide but be prepared to change our views if the data changes.

Sincerely,

Steven M. Bowser and Christopher L. Phalen

		Series H
Manager’s Commentary		(Enhanced Index Series)
February 15, 2007		(unaudited)

LOGO

Advisor, Northern Trust

To Our Shareholders:

Series H of the SBL Fund - Enhanced Index Series posted a total return of 15.55% for the year ended December 31, 2006. Its benchmark, the S&P 500 Index, was up 15.79%.

The U.S. equity market ended up for the fourth straight year in 2006. The first half of 2006 was characterized by mixed macroeconomic and earnings reports, inflation concerns, record oil prices, and increased geopolitical risk. The second half of the year saw a sustained market rally fed by falling oil prices, the announcement of several large M&A deals, and the Fed’s decision to pause on rates.

The Series 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 the individual stocks, sectors, industries, style and size.

Keys to the Series’ Gain

Driving the Series’ positive outperformance in 2006 was the portfolio’s exposure to companies with healthy accruals, management share buybacks, and book-to-price, whereas exposure to companies with analyst diffusion and momentum was a detractor.

During 2006, the market rewarded moderately valued securities that displayed attractive growth characteristics, especially within the Information Technology sector, where our bottom up stock selection model worked most effectively. Within that sector, the fund achieved a 15.4% return relative to the benchmark sector return of 8.6%, while maintaining neutral exposure to sectors at the portfolio level. The Series’ portfolio construction methodology is designed to ensure the portfolio will have neutral exposures to all sectors in line with the benchmark, and relies on stock selection within sectors to enhance returns.

Despite a discernable slowdown in U.S. economic growth, global financial markets powered ahead in the final quarter of 2006. Still-higher corporate profits and falling oil prices were the most prominent catalysts driving further advances in risk-based security prices. As 2006 came to a close, a series of positive economic reports also suggested that investors’ percolating recession fears were perhaps overblown, and the U.S. economy’s much-coveted soft-landing was safely “wheels down.”

Investors enter 2007 with a backdrop of favorable economic and financial trends: Global growth remains solid and the global economy appears set to strengthen in the first half of this year, sustaining the strongest business cycle since the early 1970s; credit and liquidity are plentiful; company balance sheet strength is its strongest in a decade; and corporate earnings remains in record territory as U.S. companies report better-than-expected results for the fourth quarter.

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

		Series J
Manager’s Commentary		(Mid Cap Growth Series)
February 15, 2007		(unaudited)

LOGO

Advisor, Security Management Company, LLC

LOGO

James P. Schier

Senior Portfolio Manager

To Our Shareholders:

Series J of the SBL Fund - - Mid Cap Growth Series posted a return of 4.93% for the year. These results lagged the benchmark, the Russell 2500 Growth, which gained 12.26%, and the median peer return of 8.70%.

Our approach to the Series is to seek securities of companies that are able to grow and/or reinvest in increasingly profitable ventures and hold them over three to five 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.

Stock Selection in Financials and Materials Helped Performance

Stock selection in financials was driven predominantly by First Marblehead Corporation, appreciating 76%. First Marblehead was driven brutally low on misplaced fears of competition and client losses that eventually proved to be ill-founded concerns. The Series benefited by acquiring the stock during this period of opportunity.

Stock selection was also positive in the materials sector lead by a 63% gain in Pactiv Corporation. Pactiv is a packaging company best known for its Hefty consumer plastic bag lines. It posted very solid earnings results in the face of commodity price input pressures.

Overweight Energy Sector Weight and Energy Stock Selection Negatively Affected Returns

The Series’ average energy weighting of 17% versus 7% for the benchmark provided a headwind as energy was a below average performer in 2006. Evergreen Energy, Inc., formerly known as KFx, declined 42%. Evergreen Energy suffered as investors moved away from the coal industry and short sellers spread negative rumors about the company. None of the rumors have proven to have any validity to date. We remain confident that the weakness in the stock is transitory and that the stock’s prior price levels can be easily re-attained. Evergreen Energy has a significant technological lead as the first company to provide a clean coal technology. We believe the clean coal industry has substantial competitive barriers, but will be a scalable business with a large addressable market for its product.

2007 Market Outlook

We continue to expect lack-luster returns for the market in 2007. This is similar to our outlook for the past two years, though the market did quite well.

Despite this, we remain firm on our outlook based on our bottom-up research rather than any global macro forecast. Most companies appear to be operating at very high levels of profitability and it is very difficult to confidently predict continued margin expansion. At present, the market is acting with a high degree of complacency.

The prevailing attitude appears to assume that either the Federal Reserve will panic and ease in the face of any operating weakness that is widespread or that the private equity market will bid for any public company that trades down. We view the recent M&A activity as somewhat bearish. If companies had abundant reinvestment opportunities in their core businesses, they wouldn’t need to pay inflated prices for acquisition candidates. Most recent mergers seem to fit the “acquisition out of desperation” category rather than the “acquisition of opportunity” camp.

Also in this environment, we have seen fewer companies with large revenue growth or large profit margin expansion potential. This is the major reason we maintained the energy overweight last year, even though the commodity price appeared extended and inventories were starting to build. The world consumes about six to seven barrels of oil for every new barrel discovered. Our research suggests that there is less excess capacity than is generally perceived. This coupled with the general political instability in key geographical regions suggests to us that energy could have a move again.

Industrials are also another sector that seems to offer good opportunity. The holdings we have in this sector are generally biased toward infrastructure and energy efficiency names that should benefit from pent up demand and a weaker dollar environment.

On behalf of Security Management Company, I would like to thank you for placing your trust and money with us.

Sincerely,

James P. Schier, Senior Portfolio Manager

Portfolio Manager

Environment

Despite a sharp decline from mid-May through mid-June, U.S. stocks rose strongly in 2006, the market’s fourth consecutive year of gains since the end of the 2000-2002 bear market. In fact, several major indexes reached six-year highs, if not record levels. Equities were lifted by substantial merger and leveraged buyout activity, continued strong corporate earnings growth despite an economic deceleration, and declining oil prices and long-term interest rates in the second half of the year. Investors were also pleased that the Federal Reserve, which increased the federal funds target rate to 5.25% by mid-year, refrained from raising it in the last six months in anticipation that slower economic growth would allow inflation to moderate over time.

U.S. bonds produced good returns in 2006, thanks primarily to favorable performance stemming from falling intermediate- and long-term interest rates in the last six months. The economy appears to be in the middle of a “soft landing”, a period of below-average growth during an economic expansion that allows inflation and interest rates to ease but does not result in a recession. High-yield corporate bonds substantially outperformed investment-grade issues, as investors seeking higher returns continued to embrace risk. In the high-quality universe, mortgage-backed securities fared best, but asset-backed and corporate securities also did well. Treasuries lagged, as yields across all maturities at the end of 2006 were higher than at the end of 2005.

Non-U.S. stocks outperformed their domestic counterparts, as returns were enhanced by the U.S. dollar’s weakness versus European and some Asian currencies. Emerging markets did best, led by shares in Latin America. In the developed regions of the world, European equities produced excellent returns, whereas Japanese stock gains in U.S. dollar terms were more moderate. The MSCI EAFE Index, which measures the performance of equities in Europe, Australia, and the Far East, returned 10.40%.

Performance

Series N of the SBL Fund - Managed Asset Allocation Series returned 12.08% for the year ended December 31, 2006, outperforming its 60% S&P 500/40% Lehman Brothers U.S. Aggregate benchmark, which returned 11.11%. Overweighting stocks relative to bonds added to results. The S&P 500 returned 15.79% over the past year, and the Lehman Brothers U.S. Aggregate Index returned 4.33%.

Portfolio Highlights

At the start of the year, the Series had a 6% overweight in stocks and ended with a 3.5% overweight in stocks which benefited overall performance. Although we remain over weight stocks versus bonds, we have moderated our overweight position in light of lower economic growth expectations.

Stocks significantly outperformed bonds during the year. Series performance was helped by both the U.S. large-cap and international equity components. Following a prolonged period of outperformance by small-cap stocks and due to less compelling valuations, we have been favoring large-cap over small-cap stocks. Against a backdrop of potentially lower U.S. growth, sectors that are more sensitive to the domestic economy, such as small-cap stocks, may face a more challenging profit environment.

Outlook

Economic growth and corporate profits remain supportive of equities, although both are likely to trend lower reflecting the more moderate growth environment and input price pressures.

Sincerely,

Edmund N. Notzon,

Portfolio Manager

Performance

Series O of the SBL Fund - Equity Income Series returned 18.82% during the year, outperforming its benchmark the S&P 500 Index return of 15.79%. The portfolio also outpaced the Lipper Equity Income Funds Index, a measure of the performance of leading equity income funds. Effective stock selection and allocation decisions across a number of sectors helped the portfolio beat its benchmark. Energy was the only sector that detracted from relative returns.

Market Environment

Every sector contributed positively to the index’s gains for the year, led by telecommunication services; energy and utilities also per formed very well. Health care performed the worst of the broad sectors but was still up more than 7%. Information technology was the only other sector in the index to post single-digit returns for the year. Looking at returns by size among the S&P indexes, large- and small-caps outperformed shares of medium-sized companies, while value again outperformed growth by a wide margin.

Portfolio Review

Stock selection in industrials and business services was key to the portfolio’s outperformance, led by positioning in the machinery and commercial services and supplies industries. The single largest contributor in the sector was equipment company Deere, which enjoyed record fourth-quarter earnings. Waste Management was a leading contributor in the commercial services industry, as healthy economic growth early in the year meant strong demand for its products.

In information technology, effective stock selection and an under weight to this lagging sector contributed to relative results. In particular, the portfolio had no exposure to the relatively poor performing Internet software and services industry. It was a similar story in computers and peripherals, where the portfolio was overweight in Dell, which had negative returns for the year. At the same time, we were over weight in IBM, which rallied after reporting strong third-quarter revenue growth. It’s worth mentioning that we added select tech names where we saw attractive values, building a sizable position in Microsoft during the year.

Health care was another sector where stock selection and an underweight position helped relative returns. The portfolio’s health care holdings are focused largely on the pharmaceutical industry, which performed well for the full year. Merck was the leading contributor in this segment, benefiting when one of its vaccines was made part of the routine vaccination schedule for girls.

At the other end of the spectrum, our performance would have been even better relative to the benchmark but for disappointing stock selection among energy shares. An underweight to ExxonMobil and poor performance by portfolio holding Anadarko limited the portfolio’s relative return.

In addition, our stock selection detracted in both the telecommunication services and consumer discretionary sectors; however, overweights to these winning sectors made them positive contributors overall.

Outlook

Going forward, we expect the pace of corporate earnings growth to slow along with the economy, though we still find equity valuations to be reasonable-valuations are neither too high nor compellingly attractive, and liquidity is good. Overall, we’re generally constructive on the outlook for stocks over the next few years, and we think the greater risk today is not a substantial decline from current levels but rather the improbability of earning higher-than-average returns over the foreseeable future. We will continue to employ the discipline that has served investors well over the years, seeking out reasonably valued stocks of high-quality companies while monitoring general economic conditions.

Sincerely,

Brian C. Rogers, Portfolio Manager

Manager’s Commentary

February 15, 2007

Series P

(High Yield Series)

(unaudited)

Advisor, Security Management Company, LLC

David Toussaint

Portfolio Manager

To Our Shareholders:

The high yield market, after producing lackluster results in 2005, came roaring back with an 11.9% return in 2006, its second best year since 1997. The U.S. economy’s continued growth allowed corporations to continue to increase profits and to further generate cash flow and improve their balance sheets, which helped move the high yield default rate near historic lows. At mid-year 2006, the Federal Reserve paused in its interest rate tightening cycle and this provided a spark to the equity and high yield markets. Series P of the SBL Fund—High Yield Series recorded a 11.18% return and the Series’ peer group was up 10.1% for the year. Part of the index's strong return is due to the large index weightings of automotive giants, General Motors and Ford. Both of these are around 6% of the index and GM returned 25% and Ford 22% during 2006. The high yield index without these two would have returned 10.2%, a full 1.7% lower. The high yield market was able to keep pace with the S&P 500’s return of 15.8% and easily outdistanced other competing fixed income returns such as government bonds which returned 3.5%, higher quality corporate bonds at 4.3%, and leveraged bank loans at 7.1%.

One of the primary reasons for high yield’s strong performance was the high yield corporate bond default rate nearly reaching historic lows. The high yield corporate default rate, which was expected to increase from 2005’s 2.3%, actually fell throughout the second half of 2006 and finished the year at 1.8%, the lowest since April 1997’s 1.7%. As a result, high yield corporate bond spreads, after widening slightly in the second quarter, tightened significantly in the second half and nearly reached historic lows by year-end.

The biggest story for 2006 was the amount of new issuance in the high yield market. In 2006, a record $142.4 billion was issued, surpassing the previous record of $137.3 in 1998. The issuance resulted from highly publicized mergers, acquisitions and leveraged buyouts. In fact, the top three LBO-related issues were almost $6 billion each. New issuance is expected to remain near these levels in 2007 as these transactions continue.

Shorter Maturity Bonds Provide 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 shor ter 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. Furthermore, most of these positions were in higher coupon issues. With ample liquidity in the bank loan market, these companies were able to refinance these bonds and tendered them at a premium. One such holding, Evergreen Aviation, returned 30% as it was able to refinance its bonds with a new bank loan.

Specific Portfolio Investments Enhanced Returns

The Series was able to enhance its return by investing in some lower quality, higher yielding securities. As the liquidity in the market was abundant, many of the Series’ holdings benefited. One of the Series’ best contributors was Worldspan, a travel services company, which returned 31% as air travel and lodging soared and the company was acquired in December. GMAC, the finance subsidiary of General Motors, returned 25% as a controlling interest in the company was sold to a private equity consortium and the corporate credit ratings were upgraded. United Rentals, an equipment rental company that is leveraged to the economy and to commercial construction booms, returned 20%.

Airline Exposure Proved Successful

The Series’ overweight to the airline sector helped the Fund. The Series was positioned in EETCs (Enhanced Equipment Trust Certificates) that performed well with the recovery in the airline industry and with the increasing value of the underlying aircraft collateral, returning around 20%, The Series’ position in these securities was a more conservative strategy to increase exposure to a risky industry.

Underweight to Riskier Large Issuers Hurt Performance versus Index

As mentioned earlier, some of the largest issuers in the index produced great returns in 2006. GM and Ford, each with a weighting of 6% of the index, returned approximately 25% and 22%, respectively. Charter Communications, a highly leveraged cable television company and 1.5% of the index, returned 34%. The Series had only a 2% weight in GM and 0.5% weight in Ford throughout the year and did not hold Charter. The Series does not think it is prudent to hold large concentrations in one issuer and typically will not hold more than 3% in any one issuer. Charter remained free cash flow negative throughout the year but was helped by some debt restructuring and the liquidity in the market.

Manager’s Commentary

February 15, 2007

Series P

(High Yield Series)

(unaudited)

Outlook and Strategy for 2007

For 2007, the economy’s growth rate is expected to moderate. The corporate default rate is expected to slightly increase throughout the year and possibly reach 2.5% to 3% by year-end, but still remain well below the long run average of around 5%. The significant increase in mergers, acquisitions and leveraged buyouts may continue to help the high yield bonds for those companies being acquired. However, as a result of these leveraging transactions, new issuance will be of much lower quality. Additionally, highly levered issuers will be less able to weather an economic slowdown. Lower quality issuance may cause the default rate to increase over the next few years. Therefore, the Series will continue to hold shor ter maturity bonds to reduce interest rate and credit risk, while oppor tunistically adding selective lower quality securities to enhance returns.

Thank you for being an investor in the Series.

Sincerely,

David Toussaint, Portfolio Manager

I. Charles Rinaldi

Portfolio Manager

To Our Shareholders:

This year’s market performance surprised many investors, especially those who thought the small cap, emerging and real estate markets had cooled off at the end of 2005. Small cap stocks, evidenced by value stocks in the Russell 2000 Index, turned in a very strong 4th quarter to finish the year at 23.48%. Series Q of the SBL Fund - Small Cap Value Series returned 13.41% in 2006, underperforming the Russell 2000 Value. As we look back to September 2005, we note the value of the portfolio’s energy stocks contributed to the overall investment results for 2005. We believe the portfolio’s natural gas infrastructure and crude oil producers stand to outperform the market as domestic companies race to ramp up supply across all energy sub-industries, in light of strong global demand for natural resources. In addition, our thorough stock selection in a number of industries has positioned the portfolio to outperform the market. With respect to the index’s strong performance in 2006, our significant underweight in banks and real estate investment trusts (REITs) was a major source of underperformance versus the benchmark. On a capitalization basis, large caps outperformed in December but small caps outperformed for the year. This was the eighth straight year that the Russell 2000 Index outperformed the S&P 500 Index. The two most recent years, however, have seen that margin narrow.

Our selection of materials and industrial processing stocks for the Series is comprised of 29 stocks that have met our requirements for inclusion in the portfolio. For the year, our materials stocks, specifically steel, chemical and gold, added the most value in terms of contribution to return. Much of the drive behind steel stocks has been the winds of worldwide steel mergers. While the steel stocks in the portfolio make up a small percentage of the total, the excellent returns in this area added over 1% to the year’s return. Chemicals stocks were also strong; a welcome change. Our identification of these stocks took place a number of years ago, with many of the companies coming through our intrinsic value process.

Gold dipped late in the year, yet still finished up 20% for the year. Gold mining stocks represent a small part of the portfolio, and have been solid performers, displaying sustained strength over the past four years. Paper companies staged a turnaround after a tough year in 2005. A top ten holding, Chicago Bridge & Iron, was up in the year. The power, environmental and natural gas services company continues to win large projects and has a significant backlog in the pipeline. We saw weakness in synthetic fiber company, Wellman and in Intertape Polymer, a resin and synthetic products company. Higher commodity prices, among other factors, caused pressure on these companies. Fifteen industries are represented in this sector, diversifying exposure to a broad slice of these types of stocks. For 2007, we look to the high cash levels at companies and the overall liquidity in the system to push projects at each of these industrials.

Total holdings in technology, a place where we have found cheap stocks and good values, have increased in the year. At least one of the themes we are seeing materialize is in radio frequency identification (RFID), a technology to allow for better inventory control in warehouses and stores. We’ve identified undervalued companies with excellent prospects and strong balance sheets as potential candidates. Technology stocks are represented by 17 companies spread throughout multiple sub-industries, including enterprise software, semi-conductors, testing hardware, and networking to name a few. For the year, we saw a small group of unrelated companies experience increased volatility in their prices. A significant detractor was Embarcadero, mired in an accounting issue. On the positive side, Symbol Technologies, a maker of handheld scanners commonly used at checkouts, was acquired by Motorola in September.

Cray Computer had a strong year, adding value to the portfolio’s return. The supercomputer maker in Seattle won a number of government and education contracts, fueling its stock price. Cray, a small niche player in a large market, has a long history developing large scale computers. Intermec, a company involved in barcode technology and also RFID research and development, was down sharply in the year. The company is in the midst of restructuring and has announced a reduction in its workforce. For 2007, we look to our selection of technology stocks to add value relative to the index.

The portfolio’s consumer stocks were up in the year; however, they underperformed the benchmark’s return in this sector. Our over weight in commercial services proved to add value to the year’s results from a broad group of companies.

Consumer stocks represent about 17% of the portfolio, with half of these stocks in commercial services, an area where we have found attractive valuations. ABM Industries, a company servicing high rise buildings, is an

	Series Q

example of a well run company with large contracts to run everything from janitorial to security operations for companies. Commercial information services company ProQuest was off sharply, dragging down the sector following its announcement of a potential restatement of quarterly earnings. Traditional retailers contributed to performance, but underperformed the market. We have found the best value in companies with predictable revenue streams, such as those found in commercial services.

Our overweight in energy stocks helped boost performance for the year. Despite widespread concern over energy prices in the summer of 2006, the portfolio’s oil well and natural gas equipment and service stocks per formed well relative to the index, adding almost 200 basis points to the year’s return. We believe we are in a multi-year period of capital projects expansion in this industry, due to an extended time of underinvestment in domestic energy projects. Under water pipeline repair company Oceaneering International had a strong year, up over 50%. The company, which utilizes remote operated vehicles to repair lines, serves a niche market in deep water pipeline repair and has been an excellent addition to the portfolio. Global Industries, a top holding in the portfolio, began serving the offshore oil and gas industry over 25 years ago and has evolved into one of the largest providers of offshore services in the Gulf of Mexico. The company’s earnings have been improving as the framework laid a number of years ago has continued to reap benefits for shareholders.

Key Energy Services, also a top holding, continues to post improving rig hours in the U.S. and internationally amid strong demand for its services. The company has yet to file regulatory documents for previous years, a situation we are monitoring closely. Helmerich & Payne, a Tulsa, OK-based driller, was down in the year, despite a rather strong earnings announcement in November. Since September 2005, we have been reducing portfolio holdings in crude oil related companies, on our thesis that while there is opportunity in the long-term in these stocks, near term pressure may not be favorable to owning oil stocks. We witnessed extended volatility in oil throughout the year and used our vast research to steer us from a negative impact on performance. Lastly, another Tulsa-based oil service company, Matrix Service, positively contributed to the year’s return. In utilities, Cincinnati Bell continues to increase its revenue and operating income, sending its shares up in the past year. The company fits our investment criteria, having a solid customer base and multiple lines of business.

Financials were very strong in the year and our under weight in the area hurt our performance. The benchmark’s financials sector makes up 35% of the entire index, dominated by banks and real estate investment trusts (REIT). Our bottom-up process has identified a small number of REITs. The portfolio currently maintains approximately 4 percent in property and casualty insurance companies, an area where we believe value exists. REITs have been a large part of the index’s performance for the year; however, in December the small cap portfolio outperformed in this area.

Our underweight in banking and REITs has been an area of underperformance due to the continued extraordinary returns seen in commercial property, hotels and other related real estate vehicles. We have found a select number of REITs, of which some are recent IPOs, and added them to the portfolio throughout the year. We also continue to favor some insurance companies on the thesis their valuations may not be fully realized.

In healthcare, the services industry comprised of companies providing ser vices to hospitals, nursing homes, prisons and clinics, was the leading contributor in our healthcare stocks for the year. Gentiva Health Services and Healthcare Services Group were steady per formers throughout the year. Gentiva provides comprehensive home health services including nursing in the U.S. In February, Gentiva acquired the Healthfield Group, another provider of services to southeastern states with over 130 locations. Healthcare Services Group provides housekeeping, laundry, linen and food services to the healthcare industry. Laundry and linen represent a significant part of the company’s revenue. The portfolio is slightly over weight in the index in healthcare.

Our healthcare facilities stocks added value to the year’s performance. The portfolio has a small exposure to biotech research companies. One stock is Infinity Pharmaceuticals, a cancer drug development company, which had a busy year making progress on a number of its cancer drugs and completing a reverse merger with Discovery Partners. In pharma stocks, the portfolio’s holdings detracted largely due to CV Therapeutics, which was pushed lower on a delay in obtaining regulatory approval for its main drug Ranexa. Late in the year, the company filed for EU approval of its heart drug, in the face of domestic regulatory challenges.

The eight transportation stocks added a small contribution to the year’s return, with railroader Rail America coming in with a strong year, up nearly 50%. The short-haul transporter agreed to be sold to a hedge fund group at a 32% premium to its trading price in mid-November. In air transport, an industry in which the portfolio has 5 holdings, results were flat for the year. EGL Inc. was a detractor in this sector, pushed lower by flat revenue from its air transport segment, which accounts for over 60% of its sales. Slightly over 5% of the portfolio is invested in transportation related stocks.

	Series Q
Manager’s Commentary	(Small Cap Value Series	)
February 15, 2007	(unaudited	)

Producer durables account for approximately 2% of the portfolio, versus 6% in the index. Our allocation to this area was a detractor to performance; in addition, stock selection also did not work in our favor. In the past year, we have begun adding manufactured housing related stocks, on our belief that the value proposition for these types of companies fits well into current housing climate. Late in the year, these stocks were not favored by investors, being dragged down by the market’s overall negative investment view towards housing.

Thank you for your confidence in our investment team. We wish you all the best in 2007 and look forward to our partnership for many years to come.

Sincerely,

		Series V
Manager’s Commentary		(Mid Cap Value Series)
February 15, 2007		(unaudited)

LOGO

Advisor, Security Management Company, LLC

LOGO

James P. Schier

Portfolio Manager

To Our Shareholders:

Series V of the SBL Fund - Mid Cap Value Series posted a solid return year gaining 14.66%. While these numbers were better than most broad market indices, the results lagged the gains provided by the Series’ benchmark. The Russell 2500 Value index was up 20.18%, but exceeded the Series’ median peer fund return of 14.46%.

Our approach to the Mid-Cap Value Series is to seek appreciable securities of companies that are able to grow and/or reinvest in increasingly profitable ventures and hold them over three to five 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 priced at or below a market multiple that are able to increase their return on invested capital over time.

Stock Selection in Energy, Consumer Staples, and Financials Drove Outperformance

McDermott, an energy company, gained 71% during the year. The company benefited from strong end markets in marine oil drilling construction and nuclear power. The company was also the beneficiary of a favorable resolution and settlement of its asbestos liabilities.

Archer Daniels Midland gained 55% as it continued to benefit from interest in its ethanol production capabilities. Having realized a four-fold appreciation in our investment in this stock since 1999, we sold our entire position in 2006.

Stock selection was also favorable in financials driven predominantly by First Marblehead, appreciating 151% during 2006. First Marblehead was driven brutally low on misplaced fears of competition and client losses that eventually proved to be ill-founded concerns. The Series benefited by acquiring the stock during this period of opportunity.

Overweight Energy Sector Weight and Energy Stock Selection Negatively Affected Returns

The Series’ average energy weighting of 15% versus 4% for the benchmark provided a headwind as energy was a below average performer in 2006. Evergreen Energy, formerly known as KFx, declined 42%. Evergreen Energy suffered as investors moved away from the coal industry and short sellers spread negative rumors about the company. None of the rumors have proven to have any validity to date. We remain confident that the weakness in the stock is transitory and that the stock’s prior price levels can be easily re-attained. Evergreen Energy has a significant technological lead as the first company to provide a clean coal technology. We believe the clean coal industry has substantial competitive barriers, but will be a scalable business with a large addressable market for its product.

2007 Market Outlook

We continue to expect lack-luster returns for the market in 2007. This is similar to our outlook for the past two years, though the market has done quite well.

Despite this, we remain firm in our outlook based on our bottom-up research rather than any global macro forecast. Most companies appear to be operating at very high levels of profitability and it is very difficult to confidently predict continued margin expansion. At present, the market is acting with a high degree of complacency.

On behalf of Security Management Company, I would like to thank you for placing your trust and money with us.

Sincerely,

James P. Schier, Senior Portfolio Manager

Manager’s Commentary		(Small Cap Growth Series)

Bill Wolfenden

Portfolio Manager

To Our Shareholders:

The stock market and small-cap stocks continued their strong run in 2006. After three years of solid performance, 2006 proved to be a strong follow-on to what is now a multi-year small-cap rally. Unfortunately, Series X of the SBL Fund - Small-Cap Growth Series did not fare as well in 2006. The portfolio finished the fourth quarter with a 7.68% gross of fees (7.53% net of fees) rise, slightly trailing the 8.77% return of the benchmark Russell 2000^® Growth Index. For the calendar year, the portfolio was up a disappointing 5.71% gross of fees (5.13% net of fees) compared with a strong increase of 13.35% for the benchmark.

Although the portfolio has often trailed in sharp small-cap rallies like those in the first and fourth quarters of 2006, our underperformance for the calendar year can be attributed to poor stock selection. We endured a number of problem stocks in the technology sector, which contributed nearly 50% of our 2006 underperformance. We are disappointed with this year’s return, but retain confidence in our investment process, which has served investors well over longer periods of time. In fact, we saw some encouraging performance signs in the fourth quarter that give us reason for optimism as we enter 2007.

Technology, Energy Sectors Yield Positive Returns

The technology sector was a source of positive returns in the fourth quarter. Over the past two quarters, our tech exposure has eased as we seek to concentrate assets in only the highest-conviction companies. That paid off as we experienced healthy gains from a number of top 20 positions, and avoided any further meaningful tech stock problems.

Omniture provides online business optimization software to a broad range of institutional clients. The company went public in summer 2006, and we started our position at that time. We built the position as the stock treaded water for much of the summer. In Omniture we have a business in a large secular growth market that is capable of growing both the revenue and the earnings line at more than 50% year over year. The stock provided a strong source of fourth quarter returns. We also enjoyed strong gains from Equinix, a leading provider of co-location data centers for businesses’ critical Internet and Internet Protocol operations. The stock was a strong contributor to gains in the second half of 2006.

One company in the tech universe that exhibits the attributes we look for in our process is SRS Labs. SRS had a breakout year in 2006, and we believe that the future looks bright for the company. SRS has a patented, defensible market position in delivering surround-sound systems and audio enhancement products for the flat-panel TV, mobile handset, automotive, PDA, PC and home theater markets. While operating results were satisfactory, the stock treaded water. We remained patient because the company possesses the critical elements that we look for: a definable competitive advantage, attractive valuation, and solid long-term anchor points (long-term goals and objectives that we or the company’s management team have set) around which it was growing its business.

We believed that SRS Labs could shed its money-losing semiconductor business and focus solely on its licensing business, which would greatly lower costs and improve margins, and free up management bandwidth to focus on new licensees and accelerate growth. In addition we believed that over time, SRS would gain market share to the point that it could tap into high-volume applications such as flat-panel TVs in China and mobile handsets (Motorola and Samsung were major wins). Management executed on its plan and now has a huge unit-growth opportunity as its technology is designed into many of the above-mentioned customers’ appliances. In essence, SRS has built a solid franchise through its design wins, and a waterfall of license revenues is imminent. We saw that come through in strong third quarter 2006 earnings results, and the stock responded with a 150% increase over its August low. This sharp rise in a short period of time has prompted us to reduce our position. We think SRS is in the early stages of discovery by other small-cap investors, however, and that we will be rewarded for early recognition and patience.

Energy-related positions also contributed positive returns in the final quarter, after proving difficult for much of the year. We had good returns from Superior Energy Services and Oil States International. Both companies provide equipment and services to offshore and land-based oil and natural gas drillers. The stocks had been beaten down over the summer and enjoyed a nice rally through the fourth quarter. We finished the year with modest energy exposure of approximately 5%, less than the benchmark weighting. We expect a tougher environment for these stocks in 2007.

Financial Sector Mixed

Financial services currently represent approximately 14% of the portfolio, a healthy overweighting with the index. We own a broad range of companies in this segment, ranging from specialty insurance providers, to asset management and private banking, to companies leverging technology across a number of financial ser vices applications. Some of these companies endured stock declines in the fourth quarter, detracting from our returns during the period. Investment Technology Group provides a number of trade management and execution services to money managers. Its stock declined during the fourth quarter as October trade volumes from its client base were lower than expected. We viewed the trade volume decline as transitory, and confirmed that long-term anchor points for the business remained solidly in place. The weakness hurt fourth quarter returns, but the stock has climbed back from much of the decline.

Online Resources Corporation is a leading provider of online banking technology services to small banks. It’s capturing significant market share as the small-bank market seeks to modernize its ser vice offering with online banking and automated bill payment. The company acquired Princeton eCom last year, thereby bolstering its client reach and removing a

competitor from the marketplace. The acquisition looks to be dilutive in the short-term, which prompted a decline in the stock in the fourth quarter. We remain optimistic about the long-term opportunity and retain our position in Online Resources.

2007 Outlook

Interest rates have stopped rising (at least for the time being), oil prices have declined, and it seems as though the housing correction is near an end. These headwinds have historically been bad for the consumer and for small companies, yet the broad stock market, and small-caps have per formed well throughout. I am looking forward to a time when the wind may actually be at our backs for a change, and that could be 2007. As I have mentioned in previous letters, however, the Series is not dependent on positive macro events and is structured for flat-to-modestly positive growth in the Gross Domestic Product. The Series 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 measure the success (or the lack thereof) by pegging them to anchor points. We believe that fast-growing companies with seasoned management teams, unique business models, and a strong competitive advantage can usually achieve their goals over time and hit these anchor points. When this execution success occurs, great stock performance often accompanies it.

Looking to 2007, I continue to believe that our investment process works over the long-term, which is reflected in our long-term results. As a fellow investor in the strategy, I thank you for your continued confidence and support.

Sincerely,

Bill Wolfenden, Portfolio Manager

Manager’s Commentary		(Select 25 Series)
February 15, 2007		(unaudited)

Advisor Security Management Company, LLC

Mark A. Mitchell

Portfolio Manager

To Our Shareholders:

Series Y of the SBL Fund - Select 25 Series returned 7.54% in the year, lagging the benchmark Russell 1000 Growth Index’s return of 9.07%, but out performing the Series’ peer group median return of 6.37%. Poor stock selection was only partially offset by solid sector positioning in 2006. While being disappointed that our results were below the benchmark, we believe that our approach delivers performance over the long-term.

Our bottom-up research driven investment process attempts to identify companies that have a competitive advantage or have the ability to become more competitive in the future. We focus on owning these companies for three to five years or longer which we believe differentiates us from a majority of our peers and ultimately allows us to make better investment decisions. We buy these companies when their current price trades below their intrinsic value. We closely monitor each company’s progress. We will sell a company if the valuation no longer makes sense, we’ve made a mistake and our investment thesis is no longer valid, or we have a more attractive investment alternative.

We ultimately structure the portfolio with 25-30 names. This philosophy is applied to a broad range of growth names.

Financials and Technology Stocks Top Performers

The Series’ Financial holdings were up 54% compared to 17% for the index. This was driven almost entirely by our position in First Marblehead, up over 150%. III-placed short-term concerns over the company’s competitive position offered a great buying opportunity for a leading student lender with a significant competitive advantage as a result of its loan underwriting capability, superior economics, and additional value-added services.

The Technology sector was up 12% versus the comparable sector index return of 7%. The largest contributor was an overweight position in Cisco, up 60%. Cisco benefited from strong enterprise equipment demand and continued solid business execution. ADC Telecom had a negative impact, down 35%. The company was hurt by unanticipated spending delays by telecom carriers as the industry has undergone significant consolidation.

Energy and Industrial Sectors Disappoint

The Energy sector was down over 14%, compared to up 4% for the benchmark. Evergreen Energy, down 42% (previously known as KFx), and BJ Services, down 20%, both contributed negatively to the fund. Evergreen Energy was hurt by concerns over the viability of the initial production results of its proprietary clean coal technology. BJ Services was impacted more generally by the recent exodus from oil services related names as a result of a weakening energy commodity market.

Holdings in the Industrial sector performed poorly this year. We were positioned to take advantage of several unique opportunities in companies that benefit broadly from strong global economic growth. Concerns regarding a slowdown in the U.S. have impacted the group. We still like the fundamentals of the companies we own, including FedEx Corporation, W.W. Grainger, L-3 Communications, and Shaw Group.

2007 Market Outlook

As we noted in last year’s shareholder letter, we’ve been concerned about a slowdown in U.S. consumer spending for some time. This concern has yet to materialize, but we still think in will happen. Lower energy prices will help, however, higher interest rates and a housing market slowdown provide likely headwinds. The Federal Reserve is walking a fine line between managing inflation risks while supporting economic growth. We’re unsure, like most in the market, what the Fed’s next move is. This uncertainty will weigh on the markets until it’s resolved.

		Series Z
Managers’ Commentary		(Alpha Opportunity Series)
February 15, 2007		(unaudited)



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

To Our Shareholders:

For the year ended December 31, 2006, Series Z of the SBL Fund - Alpha Opportunity Series total return was 13.13%, trailing the Series’ median peer group return of 13.92% and the 15.79% return for the costless S&P 500 Total Return Index. Although disappointed with the Series’ return that trailed its S&P 500 benchmark, we believe our investment approach delivers significant long-term value, as demonstrated by the Series’ cumulative total return of 60.72% since its July 7, 2003 inception, which exceeded the S&P 500’s Total Return by 10.27%.

During this period, the performance of the Series’ assets managed using the active value strategy underperformed the index, while the passive strategy of the Series performed as expected. The passive strategy replicates the index by investing in high-quality, short-term fixed income instruments and by being long the index futures. While the passive strategy provides the necessary liquidity, the active strategy focuses on adding long-term value while maintaining a risk profile that is less than the marketplace in general.

The 2006 underperformance of the Series’ assets managed using the active value strategy can be partially attributed to the strong rise in stocks in 2006 which made it difficult to make absolute return in the portfolio’s short positions. Further contributing to underperformance were the strong performances by non-theme sectors such as finance where we were not only underweighted but short in some portions.

The fundamental investment philosophy of the active value strategy rests first upon the belief that it is critical to identify the long-term investment theme governing the equity markets. These themes may persist for 15 to 20 years. Second, while we also believe that valuation adds important perspective to investment decisions, it is not an efficient means of timing purchase and sale decisions. We believe those decisions are best made using technical analysis. We believe technical analysis, the study of price trends, allows us to efficiently capture gains and avoid material losses. The third tenet of our philosophy is that changes in stock prices lead changes in fundamental corporate developments. A proactive asset management approach helps to keep our investment themes fresh and our risk levels moderate.

2006 was a year marked by great volatility. Our active value strategy investments in the Energy sector performed well as that sector returned over 22% during the year. Individual holdings remain broadly diversified within sector concentrations in Industrials and Materials of 23.5% and 22.5%, respectively. Our top five profitable positions were in these three sectors: McDermott in Energy; General Cable, Amphenol and Commscope in Industrials; and Votorantim Cellulose in Materials.

We were most disappointed in the short exposure of the active value strategy portfolio. It is very difficult to achieve an absolute positive return in a year when stocks record double digit gains. We ended the year at a low 4% short position, for the active value portion of the Series, primarily due to our constructive view of the 2007 market. The most disappointing short position for us was PNC Bank. Despite this disappointment, however, we remain negative on regional banks and select consumer stocks. Regional bank profits should continue to suffer from a competitive lending environment and an inverted yield curve. Subdued economic growth in 2007 will put added pressure on the consumer, negatively impacting the profits of restaurants and other retail companies.

We are optimistic on the outlook for stocks in 2007. Equity valuations in general remain fair across most sectors, with no individual sector appearing meaningfully overvalued. Also favoring stocks is the large amount of cash on the sidelines. These large cash positions, coupled with net equity exposures for long/short funds near historic lows, suggest stock prices will continue to trend higher in 2007. Fundamentally, the revision of third quarter GDP growth up from 1.6% to 2.0% leads us to believe that the U.S. economy is basing, thereby averting recession next year. This should allow for the resumption of the secular uptrend in commodities.

157


		Series Z
Managers’ Commentary		(Alpha Opportunity Series)
February 15, 2007		(unaudited)

There continue to be opportunities within commodities and companies related to their production. In our active value strategy, we like a broad spectrum of agricultural related stocks ranging from seed producers, such as Monsanto, to makers of fertilizers, like Potash. The agricultural theme carries over into industrial companies such as Deere and Case New Holland. Current weakness in commodities may take awhile to work out. In the meantime, opportunities in transportation and infrastructure are being addressed.

All the best for 2007,

Notes to Financial Statements

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 a 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^{^®}. 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.

The senior floating rate interests (loans) in which Series P invests are not listed on any securities exchange or board of trade. Accordingly, determinations of the value of loans may be based on infrequent and dated trades. Typically loans are valued using information provided by an independent third party pricing service. If the pricing service cannot or does not provide a valuation for a particular loan or such valuation is deemed unreliable, such loan is fair valued. In determining fair value, consideration is given to several factors, which may include, among others, one or more of the following: the fundamental business data relating to the issuer or borrower; an evaluation of the forces which influence the market in which these loans are purchased and sold; type of holding; financial statements of the borrower; cost at date of purchase; size of holding; credit worthiness and cash flow of issuer; information as to any transactions in, or offers for, the holding; price and extent of public trading in similar securities (or equity securities) of the issuer/borrower, or comparable companies; coupon payments; quality, value and saleability of collateral securing the loan; business prospects of the issuer/borrower, including any ability to obtain money or resources from a parent or affiliate; the portfolio manager’s and/or the market’s assessment of the borrower’s management; prospects for the borrower’s industry, and multiples (of earnings and/or cash flow) being paid for similar businesses in that industry; borrower’s competitive position within the industry; borrower’s ability to access additional liquidity through public and/or private markets; and other relevant factors.

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.

Notes to Financial Statements

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 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 agreement 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. Securities Sold Short – 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. If a Series makes a short sale, the Series does not immediately deliver from its own account the securities sold and does not receive the proceeds from the sale. 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 or delivering the security from its own portfolio. The Series is said to have a “short position” in securities sold until it delivers them to the broker, at which time it receives the proceeds of the sale. Certain Series may make short sales that are not “against the box,” which create opportunities to increase the Series’ return but, at the same time, involve specific risk considerations and may be considered a speculative technique. Such short sales theoretically involve unlimited loss potential, as the market price of securities sold short may continually increase, although a Series may mitigate such losses by replacing the securities sold short before the market price has increased significantly. 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.

O. Recent Accounting Pronouncements – On July 13, 2006, the Financial Accounting Standards Board (“FASB”) released FASB interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (“FIN 48”). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to e taken in the course of preparing the Company’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 but not before its last NAV calculation in the first required financial statement reporting period for its fiscal year beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implication of FIN 48 and its impact in the financial statements has not yet been determined.

In September 2006, FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (FAS 157). This standard clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosure about the use of fair value requirements. FAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. As of December 31, 2006, the Fund is currently evaluating the impact of FAS 157.

P. Senior Loans – Senior loans in which certain of the Series invests generally pay interest rates which are periodically adjusted by reference to short-term, floating rate plus a premium. These base lending rates are generally (i) the lending rate offered by one or more major European banks, such as the London Inter-Bank Offered Rate (LIBOR), (ii) the prime rate offered by one or more major United States banks, or (iii) the bank’s certificate of deposit rate. Senior floating rate interests often require prepayments from excess cash flows or permit the borrower to repay at its election. The rate at which the borrower repays cannot be predicted with accuracy. As a result, the actual remaining maturity may be substantially less than the stated maturities shown. The interest rate indicated is the rate in effect at December 31, 2006.

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:


	Management Fees (as a % of net assets)		Management Fee Waivers (as a % of net assets)
Series A (Equity Series)	0.75	%	N/A
Series B (Large Cap Value Series)	0.65		N/A
Series C (Money Market Series)	0.50		N/A
Series D (Global Series)	1.00		N/A
Series E (Diversified Income Series)	0.75		0.15
Series H (Enhanced Index Series)	0.75		0.25
Series J (Mid Cap Growth Series)	0.75		N/A
Series N (Managed Asset Allocation Series)	1.00		N/A
Series O (Equity Income Series)	1.00		N/A
Series P (High Yield Series)	0.75		N/A
Series Q (Small Cap Value Series)	1.00		N/A
Series V (Mid Cap Value Series)	0.75		N/A
Series X (Small Cap Growth Series)	1.00		N/A
Series Y (Select 25 Series)	0.75		N/A
Series Z (Alpha Opportunity Series)*	2.15	¹	N/A

*	Series Z’s management fee will range from 1.25% to 2.75% of average daily net assets as discussed below.

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 on 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 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 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 that number by the number of days in the Measuring Period and then multiplying that amount by the number of days in the current month.

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. For these services, the Investment Manager receives the following:


	Administrative Fees (as a % of net assets)*
Series A (Equity Series)	0.095	%
Series B (Large Cap Value Series)	0.095
Series C (Money Market Series)	0.095
Series D (Global Series)	0.150
Series E (Diversified Income Series)	0.095
Series H (Enhanced Index Series)	0.095
Series J (Mid Cap Growth Series)	0.095
Series N (Managed Asset Allocation Series)	0.150
Series O (Equity Income Series)	0.095
Series P (High Yield Series)	0.095
Series Q (Small Cap Value Series)	0.095
Series V (Mid Cap Value Series)	0.095
Series X (Small Cap Growth Series)	0.095
Series Y (Select 25 Series)	0.095
Series Z (Alpha Opportunity Series)	0.150

*	The minimum annual charge for administrative fees is $25,000 for Series A, B, C, E, H, J, O, P, Q, V, X, Y and Z and $60,000 for Series D and N.

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


Annual charge per account	$	5.00 - $8.00
Transaction fee	$	0.60 -$1.10
Minimum annual charge per series	$	25,000
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, 2006, 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 H, Q 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, 2006, Security Benefit Life Insurance Company, through their insurance company separate accounts, owned 100% of the outstanding shares of each Series of the Fund, except for Series P in which it owned 99%.

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 approriate equity accounts in the period that the differences arise. The following adjustments were made to the Statement of Assets and Liabilities at December 31, 2006 to reflect permanent differences:


	Accumulated Net Realized Gain/(Loss)			Undistributed Net Investment Income			Paid-in-Capital

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, H, J, N, O, P, Q, V, X, Y and Z portfolios) (the Fund), as of December 31, 2006, 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, 2006, 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 Series constituting the Fund at December 31, 2006, 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.

Directors’ Disclosure

(unaudited)

Director Approval of Investment Advisory Agreement

At an in-person meeting of the Fund’s Boards of Directors held on November 16-17, 2006, 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 competitive performance record for the year to date, and one year periods ended September 30, 2006 and strong performance for the three year period 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.

Directors’ Disclosure

(unaudited) (continued)

•

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 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.
