Co–Chief Investment Officers' Letter to the Shareholders

Jonathan Coleman
Co-Chief Investment Officer

Gibson Smith
Co-Chief Investment Officer

Dear Shareholders,

We would like to thank you for your investment in the Janus Funds. Your support is what drives us in our quest to deliver strong, consistent fund performance.

Major Market Themes

Equity markets delivered healthy gains during the six months ended April 30, 2007, amid continued evidence of strong U.S. economic growth with modest inflation. Despite a brief bout of market volatility in late February and early March, markets rebounded quickly on hopes of monetary easing by the Federal Reserve (Fed). While U.S. corporate profit growth showed signs of slowing, robust mergers and acquisitions (M&A) and private equity transactions continued to provide valuation support to equities in the U.S. and around the globe.

Continued Strong Performance

We are pleased to report that several fund managers continued to deliver strong performance compared to their peers. For the one-year period ended April 30, 2007, 81% of Janus' retail funds ranked within Lipper's top two quartiles based on total returns. For the three-year period, 68% of our retail funds achieved first- or second- quartile Lipper rankings, and 67% ranked in Lipper's top two quartiles for the five-year period. (See complete rankings on page 3).

Investment Team Depth

We're proud of the depth we've built in our investment team over the past few years. Recently, we said farewell to several long-term Janus portfolio managers who announced their retirements. In transitioning the leadership of their portfolios, we're confident that our investment team bench strength will ensure smooth transitions.

Management of Janus Global Life Sciences Fund will reside in the capable hands of Andy Acker. Barney Wilson will assume sole portfolio management responsibilities for Janus Global Technology Fund. In addition, Gibson Smith and Darrell Watters, with more than 33 years of combined investment experience, will co-manage Janus Flexible Bond Fund. Jason Groom, a seasoned fixed-income professional with 13 years of investment experience, will assume co-portfolio management responsibilities with Darrell Watters for Janus Short-Term Bond Fund, previously managed by Gibson Smith. Lastly, Craig Jacobson will join Eric Thorderson as Co-Portfolio Manager of all Janus money market funds, with the exception of Janus Tax-Exempt Money Market Fund, for which he will be sole Portfolio Manager.

It's important to note that we will continue to focus on the same investment objectives and employ the same in-depth, fundamental analysis and company-by-company approach to portfolio construction that are Janus hallmarks. We believe all of these individuals possess the skills and experience necessary to lead your Funds to strong performance.

Outlook

Looking ahead, with most U.S. equity indexes near all-time highs at the end of the period, we will closely monitor several fundamental factors for directional cues. First, despite the weakness in the U.S. housing sector and the associated credit quality issues in the subprime mortgage market, the U.S. unemployment rate was near historic lows. We intend to watch the labor market closely for any sign of a slowdown that could impact consumer sentiment and economic growth. Similarly, we plan to monitor the higher-quality prime mortgage market and other areas of consumer lending for any indication of credit quality deterioration.

Second, U.S. corporate profit growth has experienced double-digit gains for several years, which, combined with strong liquidity from corporate M&A and private equity transactions, has supported higher equity valuations. We will continue to watch both the future path of corporate earnings and the overall liquidity in the markets to determine whether current valuations can be sustained.

In summary, while there are both positive and negative factors that could influence the markets in the coming months, we view the fundamental economic outlook as positive. While inflationary concerns and questions about the strength of consumer spending abound, we feel valuations for equities are reasonable by historic standards. In fact, as overall economic growth slows, investors could place an increasing premium on the shares of companies with strong growth prospects. We believe Janus' fundamental research can be beneficial in such an environment. Regardless of the macroeconomic

climate, we remain dedicated to rewarding your confidence in Janus with strong, consistent fund performance.

Sincerely,

Jonathan Coleman

Useful Information About Your Fund Report

Management Commentaries

The Management Commentaries in this report include valuable insight from the Funds' managers as well as statistical information to help you understand how your Fund's performance and characteristics stack up against those of comparable indices.

Please keep in mind that the opinions expressed by the Funds' managers in the Management Commentaries are just that: opinions. They are a reflection of their best judgment at the time this report was compiled, which was April 30, 2007. As the investing environment changes, so could their opinions. These views are unique to each manager and aren't necessarily shared by their fellow employees or by Janus in general.

Fund Expenses

We believe it's important for our shareholders to have a clear understanding of Fund expenses and the impact they have on investment return.

The following is important information regarding each Fund's Expense Example, which appears in each Fund's Management Commentary within this Semiannual Report. Please refer to this information when reviewing the Expense Example for each Fund.

Example

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including redemption fees (where applicable) (and any related exchange fees) and (2) ongoing costs, including management fees and other Fund expenses. The example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the six-month period from November 1, 2006 to April 30, 2007.

Actual Expenses

The first line of the table in each example provides information about actual account values and actual expenses. You may use the information in this line, 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 first line under the heading entitled "Expenses Paid During the Period" to estimate the expenses you paid on your account during the period.

Hypothetical Example for Comparison Purposes

The second line of the table in each example provides information about hypothetical account values and hypothetical expenses based upon the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's 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 Fund 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 funds.

Janus Capital Management LLC ("Janus Capital") has contractually agreed to waive Janus Triton Fund's total operating expenses, excluding brokerage commissions, interest, taxes and extraordinary expenses, to certain limits until at least March 1, 2008. Expenses in the example reflect the application of this waiver. Had the waiver not been in effect, your expenses would have been higher. More information regarding the waiver is available in the Funds' prospectuses.

Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as redemption fees (where applicable). These fees are fully described in the prospectus. Therefore, the second line of each table 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 transaction costs were included, your costs would have been higher.

Fund Snapshot

For more than 36 years, this traditional growth fund has exemplified Janus' research and stock-picking abilities.

David Corkins
portfolio manager

Let me begin by emphasizing how much I value this opportunity to speak directly with my fellow Janus Fund shareholders. I am pleased to report that performance continued to improve. It was particularly satisfying to see that last year's actions – shrinking the names in the portfolio, leveraging the full resources of the research team and diversifying the portfolio more broadly among sectors – began to have a positive impact on performance.

Performance Overview

Equity markets delivered healthy gains during the period amid continued evidence of strong U.S. economic growth with modest inflation. After a brief period of market volatility in late February and early March, markets rebounded quickly on hopes of monetary easing by the Federal Reserve (Fed). While U.S. corporate profit growth showed signs of slowing, robust mergers and acquisitions (M&A) and private equity transactions continued to provide key valuation support to equities in the U.S. and around the globe.

My goal for the Fund is to provide superior long-term returns for shareholders. In practice, these potential long-term returns begin with positive absolute performance and follow with consistent execution in up and down markets. For the six months ending April 30, 2007, Janus Fund returned 10.98%. By comparison, the Fund's primary benchmark, the Russell 1000^® Growth Index returned 8.42% and our secondary benchmark the S&P 500^® Index returned 8.60%.

Utilities and Industrials Boosted Performance

Within the Fund, holdings within the industrial, consumer discretionary and utilities sectors made positive contributions to performance during the period.

Among the utility holdings, wholesale power provider, NRG Energy, generated significant gains and was the largest individual contributor to performance for the six-month period. I was initially attracted to NRG last year due to what I saw as its reasonable valuation, high free cash generation, improving returns on capital and a management team that is focused on shareholder value-creation. A buy-out of Texas-based TXU, a smaller holding in the portfolio, which also contributed positively to performance, refocused investor attention on the utility industry and led to a revaluation of the group.

Within industrials, Precision Castparts, a supplier to Boeing and other aerospace manufacturers, benefited from Boeing's market share gains in the wide body commercial aircraft market. Precision Castparts also reported improved margins and returns in its specialty metals division. While remaining constructive on the outlook for the company, I trimmed back the position as the risk/reward profile changed due to the strong increase in the share price.

It should be noted that Boeing was also a top contributor to performance for the time period, driven in part by better-than-expected margins. The company has been able to gain market share at Airbus' expense, given operational difficulties by its competitor.

Looking within the healthcare sector, Coventry Health Care moved ahead after it reported improved financial results for 2007 based on market share gains in its Medicare business. Coventry has appealing membership growth, numerous opportunities to raise margins and an attractive valuation.

Information Technology (IT) and Consumer Staples Holdings Detract From Performance

The Fund holdings within the IT and consumer staples sectors detracted from performance during the time period.

The single largest detractor from performance was Advanced Micro Devices (AMD). Our initial thesis on AMD centered on its manufacturing advantages and the potential to improve margins and returns as the company captured market share from its competitor, Intel. However, AMD's fundamental outlook has been negatively impacted by the price war taking place between it and Intel, as well as industry oversupply issues. I also thought that the company's 2006 acquisition of ATI Technologies severely diluted returns on capital. For these reasons, I elected to exit the position during the period.

Another stock that negatively impacted performance was food retailer, Whole Foods Market, which declined after reporting that comparable store sales had moderated to an 8.6% level after posting years of double-digit gains. The company also guided down future comparable store expectations. I have maintained exposure to the name, given the continued robust

Janus Growth Funds April 30, 2007 5

Janus Fund (unaudited)

outlook for growth as Whole Foods seeks to expand its store base over the next few years.

While, in the aggregate, the Fund's healthcare investments made a positive contribution to performance, select holdings declined during the time period. Varian Medical Systems, a manufacturer and distributor of laser-guided radiation therapy instruments, reported inconsistent order growth from both their domestic and international businesses. From a macro perspective, I remain constructive on the outlook for the business, driven by higher rates of cancer, increases in the number of patients qualifying for radiation treatment and reasonable reimbursement rates.

Outlook

With most U.S. equity indexes near all-time highs at the end of the period, we will closely monitor several fundamental factors for directional cues. First, despite the weakness in the U.S. housing sector and the associated credit quality issues in the subprime mortgage market, the U.S. unemployment rate was near historic lows, mitigating the impact of the housing slowdown on consumer spending and the overall U.S. economy. We will watch the labor market closely for any sign of a slowdown that could impact consumer sentiment and economic growth. Similarly, we will monitor the higher-quality prime mortgage market and other areas of consumer lending for any indication of credit quality deterioration. Second, U.S. corporate profit growth experienced double-digit gains for several years, which, combined with strong liquidity from corporate M&A and private equity transactions, supported higher equity valuations.

We will continue to watch both the future path of corporate earnings and the overall liquidity in the markets to determine whether current valuations can be sustained. We will also watch market volatility, which in recent years has been well below average compared to the past 30 years. In my opinion, volatility will likely increase in the future and so my goal is for the Fund to capitalize on the situation.

In sum, I am honored to manage Janus Fund and I want to stress that I believe my investment and incentives are in alignment with yours. Lastly, I want to commend the entire investment team at Janus, who work very hard every day to seek attractive opportunities to grow our principal.

Data presented reflects past performance, which is no guarantee of future results. Investment results and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Due to market volatility, current performance may be higher or lower than the performance shown. Call 800.525.3713 or visit www.janus.com for performance current to the most recent month-end.

The Fund's expense ratios were determined based on average net assets as of the fiscal year ended October 31, 2006. Detailed information is available in the prospectus. All expenses are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

The Fund's performance may be affected by risks that include those associated with non-diversification, non-investment grade debt securities, undervalued or overlooked companies, investments in specific industries or countries and potential conflicts of interest with Janus Smart Portfolios. Additional risks to the Fund may include those associated with investing in foreign securities, emerging markets, initial public offerings ("IPO"s), derivatives and companies with relatively small market capitalizations. Please see a Janus prospectus or www.janus.com for more information about risk, portfolio holdings and details.

Total return includes reinvestment of dividends, distributions and capital gains. The returns shown do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

The Fund's portfolio may differ significantly from the securities held in the indices. The indices are not available for direct investment; therefore their performance does not reflect the expenses associated with the active management of an actual portfolio.

12 Janus Growth Funds April 30, 2007

Janus Enterprise Fund (unaudited)

Ticker: JAENX

Fund Snapshot

This growth fund pursues companies that have grown large enough to be well established but are small enough to still have room to grow.

Jonathan Coleman
portfolio manager

Performance Overview

During the six months ended April 30, 2007, Janus Enterprise Fund gained 13.60%. By comparison, the Fund's primary benchmark, the Russell Midcap^® Growth Index, and the Fund's secondary benchmark, the S&P MidCap 400 Index, returned 11.77% and 11.98%, respectively.

Economic Overview

Materials Stocks Boost Performance

Fund performance for the period benefited from solid stock selection in the materials sector, where it held an above-benchmark weighting. Additionally, solid stock selection in the information technology (IT), consumer discretionary and healthcare sectors contributed positively to results.

Owens-Illinois, a materials holding, was our top contributor for the period. The glass manufacturer benefited from a change in management and investor optimism that new CEO Al Stroucken's focus on pricing and cost reduction could improve operating margins. This thesis gained credibility as the company put at least one high profile capital expenditure on hold in the first quarter. Over time, I think this new management focus on margin improvement could help this business become more predictable and, as a result, receive a higher valuation from investors.

Potash Corporation of Saskatchewan, Canada, also within the materials sector, was the second top-performing holding. Potash holds the world's largest excess supply of potash, a key ingredient in fertilizer. As such, the company has benefited from increasing global demand for agricultural land. Further boosting performance, the company's share of the global potash market increased with the flood of a competitor's mine late in 2006.

Financials Stocks Weigh on Results

On the downside, performance for the period was hindered by the Fund's overweight exposure to the financials sector. While the Fund did not have direct exposure to the subprime mortgage market, several individual financial services holdings were pressured by concerns that subprime mortgage delinquencies could lead to problems in other areas of consumer lending and the economy overall.

Advanced Micro Devices (AMD), an IT holding, was our largest detractor from performance in the period. AMD and rival Intel engaged in a series of price cuts that have taken a toll on margins, which undermined my confidence in the company's long-term outlook. As such, I eliminated the position in AMD.

Additionally, while the Fund's healthcare holdings generally performed well for the period, Varian Medical Systems, a maker of cancer-therapy systems, suffered. The company reported slowing order growth and longer sales cycles due to heightened competition affecting its oncology franchise. Given my concerns over changes in the company's competitive landscape, I trimmed my investment in Varian late in the period.

Outlook

With most U.S. equity indexes near all-time highs at the end of the period, I am closely monitoring several fundamental factors for directional cues. First, despite the weakness in the U.S. housing sector and the associated credit quality issues in the subprime mortgage market, the U.S. unemployment rate is near historical lows, mitigating the impact of the housing slowdown on consumer spending and the overall U.S. economy. I will be watching the labor market closely for any sign of a slowdown which could impact consumer sentiment and economic growth. Similarly, I will be monitoring the higher-quality prime mortgage market and other areas of consumer lending for any indication of a deterioration in credit quality. Second, U.S. corporate profit growth has experienced double-digit gains for several years, which, combined with strong liquidity from corporate M&A and private equity transactions, has supported higher equity valuations. I will continue to watch both the future path of corporate earnings and the overall liquidity in the markets to determine whether current valuations can be sustained.

Janus Growth Funds April 30, 2007 13

Janus Enterprise Fund (unaudited)

Going forward, I remain constructive on the market outlook, but caution that uncertainty over inflation pressures and the Fed policy could keep markets volatile in the near term. Such volatility could present me with attractive buying opportunities as I continue to rely on research-driven approaches to help identify promising investments.

As I always do in this space, I would like to reiterate to you that I am an investor alongside you in Janus Enterprise Fund. I invest a portion of every paycheck in the Fund and I have never sold a share of the Fund as long as I have managed it. I take the obligation of trust very seriously and work every day to support the trust you have placed in me and in Janus.

Thank you for your investment in Janus Enterprise Fund.

Janus Orion Fund (unaudited)

Ticker: JORNX

Fund Snapshot

This focused growth fund invests in a small number of well-researched companies, hand-picked for their upside potential.

Ron Sachs
portfolio manager

Investment Strategy

In keeping with Janus' core investment approach, I focus on individual stocks and company fundamentals. Company fundamentals are often greatly influenced by the macroeconomic environment in which businesses operate. Therefore, I closely monitor the macroeconomic backdrop that feeds the assumptions and expectations I have for each of the companies in the Fund.

At period end, I thought U.S. and global equity markets were reasonably valued based on the fact that I was able to find numerous compelling investment opportunities with what I believed to be attractive risk/reward tradeoffs. That belief was further confirmed by looking at the valuation multiples of the broad market indexes in developed markets relative to the growth expectations for gross domestic product (GDP) and corporate profits. Market participants seemed very cognizant of risk and reacted appropriately as fundamental risks changed.

Within that environment, I continued to find what I believed were great businesses with attractive valuations for the Fund. When I am able to find those types of businesses, I truly enjoy my job. My challenge as Portfolio Manager is less about discovering new attractive investment opportunities and more focused on selecting from a list of attractive risk/reward opportunities uncovered by the research analysts and portfolio managers at Janus. More compelling stock ideas should lead to fewer stocks in the portfolio. Rather than struggling to fill the Fund with many small positions with a reasonably attractive risk/reward tradeoff, I would rather cull what I believe to be great ideas that merit larger position sizes. As of period end, I believed even some of the best-performing positions in the Fund over the past six, 12 and 24 months remained compelling investment opportunities because the business fundamentals had improved in step with or ahead of the stock prices. By focusing on the long-term competitive position of a company, I was able to decide whether to hold or sell a stock based on whether its business executed and grew as I had anticipated.

Market Overview

Notwithstanding the strong recent performance of the stocks in Janus Orion Fund, I think the fact that stock indexes across the globe and in most every segment of the market, including commodities and real estate, have performed well should be a cause for concern. Therefore, I have begun to focus on possible risks, such as the existence of "bubbles," stemming from this positive environment. Unfortunately, bubbles are usually only identifiable in hindsight.

While I don't believe the overall stock market is in such a bubble, I do believe there are pockets of the investment universe that have exhibited irrational confidence. For example, real estate in Dublin sold at over 30 times rental costs and the Chinese stock market mirrored the Internet sector of the late 1990s with individual investors opening new accounts at an unprecedented rate.

These developments prompted numerous questions for me. Have other asset classes been pulled into higher valuation ranges by those bubbles? Will a collapse of any small bubble have spillover effects? Historically, bubbles have driven great fundamentals for businesses but I intend to exit early from companies in the Fund that I believe are enjoying the benefits of a market bubble.

Fund Performance

The Fund was up 13.33% during the six-month period ended April 30, 2007, versus a return of 8.34% for the Fund's primary benchmark, the Russell 3000^® Growth Index, and a return of 8.60% for the S&P 500^® Index, the Fund's secondary benchmark. A number of the top contributors to the Fund over the period were holdings where the company's business model met or exceeded my expectations.

Dade Behring and ABB Were Important Contributors

One of these holdings, Dade Behring Holdings, was the top contributor during the period. This leading player in the clinical diagnostics industry is in the early stages of rolling out a new high-volume integrated chemistry and immunochemistry analyzer. I believe the Dimension Vista analyzer should enable large hospitals to deliver faster, more accurate test results with less labor than current alternatives. In my opinion, the market underestimated the impact of the Dimension Vista, and at the same time, did not give Dade credit for its ability to execute in the small- to mid-size hospital market. I believe the clinical diagnostics industry has great potential for growth over the long term.

Janus Growth Funds April 30, 2007 21

Janus Orion Fund (unaudited)

Another important contributor during the period was ABB, a leading provider of electric grid transmission and distribution equipment and systems. I believe investors finally recognized the great pricing power that ABB enjoyed because of its technologies, long-standing business relationships and established track record of reliability, as well as the breadth and depth of ABB's competitive moat. Because of the multi-year backlog ABB has in some of its most critical end-markets, I believe the strength of its pricing power has not been fully reflected in the company's operating results.

I spoke with ABB's management about its underleveraged balance sheet and stated goal of putting cash to use in an acquisition. Accordingly, I believe the market's fears of a value-destroying acquisition are misplaced. Instead, I believe ABB faces a multi-year growth opportunity in its primary markets and can continue to create value through production rationalization and smart pricing decisions. That said, I believe there are investors who view ABB's current business momentum as a product of an emerging market bubble fueled by China's rapid industrialization and urbanization. While I agree that China has been an important driver of global growth, I do not agree that the global demand for electricity transmission and distribution infrastructure depends solely on China.

Whole Foods, Corporate Executive Board Detracted From Performance

The two largest detractors from performance were Whole Foods Market and Corporate Executive Board.

Whole Foods Market is the leading supermarket chain focused on organic and natural products. I believe it has built strong customer loyalty and has a clear path to growth through new store openings because many landlords view Whole Foods as an attractive tenant. During the period, the company disappointed on two fronts. First, same-store sales, a key driver of operating profit growth, were disappointing. I think this is likely the result of both increased competition in health-conscious products from traditional supermarkets, and the fact that many Whole Foods locations neared maximum utilization as lack of parking and long checkout lines drove incremental customers elsewhere. The other area of disappointment was in the company's projections for new store openings. The rate of new openings was lower than I expected, and the cost of each new store seemed higher than for earlier locations. While I am a long-term believer in the secular opportunity for healthy food retailing, Whole Foods' lofty valuation demanded strong results from existing stores and rapid expansion into new locations with attractive economic returns. Lacking confidence that Whole Foods would exceed market expectations, I sold the Fund's position.

Corporate Executive Board is a subscription-based consulting business with a business model that I believe should have pricing power and operating leverage as it grows. I watched the stock for years and viewed the market's reaction to a slowdown in projected growth rates as an attractive opportunity to finally establish a position. Unfortunately, the slowdown was the result of some sales force problems at Corporate Executive Board that may take longer to fix than anticipated, so the stock continued to decline after I purchased it. I believe the long-term fundamentals of Corporate Executive Board's business model remain attractive and believe the stock may still have considerable upside from here. That said, I am working to better understand the company's pricing power opportunities with existing customers in the event that reinvigorating new customer growth proves more challenging than the company anticipates.

I am excited about the businesses in the Fund and plan to continue working toward strong results in the future. Thank you for your investment in Janus Orion Fund.

28 Janus Growth Funds April 30, 2007

Janus Research Fund (unaudited)

Ticker: JAMRX

Fund Snapshot

This diversified growth fund typically pursues larger companies believed to be well-positioned for future growth.

Team Based Approach
Led by Jim Goff
Director of Research

Performance Overview

For the six-month period ended April 30, 2007, Janus Research Fund gained 15.96%, outperforming its primary benchmark, the Russell 1000^® Growth Index, which advanced 8.42% and its secondary benchmark, the S&P 500^® Index, which rose 8.60%.

Equity markets delivered healthy gains during the period amid continued evidence of strong U.S. economic growth with modest inflation. International markets were particularly strong during the period. After a brief period of market volatility in late February and early March, stocks rebounded quickly on hopes of monetary easing by the Federal Reserve (Fed). While U.S. corporate profit growth showed signs of slowing, robust merger and acquisition (M&A) activity and private equity transactions continued to provide key valuation support to equities in the U.S. and around the globe.

Janus Research Fund is comprised of the best ideas of Janus' 35 equity analysts. Stock selection within the portfolio is primarily individual analyst-driven, but benefits from debate and oversight by Janus' eight global sector research teams.

The Janus analyst team managed Janus Research Fund over the past 15 months, as of period end. It focused on driving consistency for long-term shareholders. During that time, we believe the Fund effectively captured the value of Janus' research in a highly diversified fashion. It demonstrated continuity with the formerly named Janus Mercury Fund on many levels – the portfolio was managed in a moderate risk fashion with approximately 79% of its total investments in U.S. stocks and 21% in non-U.S. stocks. More importantly, the portfolio continued to generate strong investment returns.

Janus Research Fund is different than most mutual funds in several important respects. The Fund is directly managed by Janus' analyst team. We believe there is great power in individual analysts making direct investment decisions as they are most familiar with the stocks they cover. The Fund is also managed as sector neutral, which means the Fund's exposure to different sectors is approximately the same as that of the primary benchmark, the Russell 1000^® Growth Index. This creates an element of simplicity to the Fund by allowing the analysts to attempt to generate performance through pure stock selection.

Contributors to Fund Performance

Within the Fund, positions in the materials and consumer discretionary sectors provided the largest contributions to relative performance during the period. For the six-month period ended April 30, 2007, each of our eight sector teams outperformed the relevant portion of the primary benchmark index. The top individual contributors during the period were Owens-Illinois, NVR, Companhia Vale do Rio Doce (CVRD), CapitaLand, Precision Castparts, Cypress Semiconductor, NRG Energy, Ceridian, Suntech Power Holdings and Apple.

Two materials stocks, glass manufacturer Owens-Illinois and Brazilian iron ore producer CVRD, were among the strongest individual performers during the period.

Owens-Illinois, the largest contributor, benefited from investor optimism that new CEO Al Stroucken's focus on pricing and cost reductions could drive margin growth. This thesis gained credibility midway through the period as the company put its solidly performing – but non-core – plastics packaging business up for sale.

A key supplier to booming infrastructure markets in India and China, CVRD, the Fund's third top performer, fell out of favor when it announced plans to purchase Canadian nickel producer, Inco, in August 2006. By the period's close, however, we believe the markets had warmed to the fact that the deal effectively diversified CVRD's revenues beyond iron ore and could enhance earnings.

Detractors from Fund Performance

The biggest detractors included Whole Foods Market, optionsXpress Holdings, SanDisk Corp., Varian Medical Systems, Federated Department Stores, SiRf Technology Holdings, Best Buy and Amgen.

A consumer staples stock, organic food retailer, Whole Foods Market, proved the poorest performer during the period. The stock dropped amid reduced same-store sales reports and lowered expectations for same-store sales going forward. Displeased with developments, we exited the position.

Another detractor was online options trading platform operator, optionsXpress. The company faced persistent challenges in adding new accounts, even during the traditionally busy first quarter.

Outlook

We believe our recent investment returns, both on an absolute basis and relative to the Fund's benchmarks, were unsustainably high and should not be expected to continue at

such a high level. We are gratified by the strength of our recent results, but what is even more important to us is that we produced these results without making large bets in the portfolio on individual companies or sectors. We are excited about the long-term prospects for Janus Research Fund. We have a great team of research analysts, an intensive research process and a disciplined investment process that seeks to produce a diversified portfolio of best ideas. By adding value through our research and managing risk through diversification, we hope to continue to produce strong risk-adjusted returns for our fellow investors. Thank you for your investment in Janus Research Fund.

Fund Snapshot

A growth fund that focuses on small- and mid-sized companies believed to have solid growth potential.

Performance Overview

Small- and mid-cap stocks performed admirably during the six-month period ending April 30, 2007. The Russell 2500^TM Growth Index returned 10.62%, handedly outperforming large cap growth indexes. Stocks in general shrugged off concerns surrounding subprime mortgage lending, a spike in gasoline prices and the steepest one day sell off in the Shanghai Composite Index in over a decade. Instead, investors chose to focus on the large amount of liquidity in the market and the almost daily announcements of public companies being taken private.

Janus Triton Fund returned 10.12% for the six-month period. While we are pleased with this absolute performance, we are disappointed that the Fund failed to keep pace with the Russell 2500^TM Growth Index's return.

Investment Philosophy

Since taking over management of the Fund on July 1, 2006, we have focused our attention on looking for high quality small- and mid-cap growth stocks with sustainable competitive advantages that we believe offer superior return potential over the long term. As we highlighted in our annual letter, we believe what sets us apart is a well thought out investment philosophy; a process that seeks to control risk; a talented, stable and hard working team of research analysts; and virtually unlimited resources to conduct research.

The Concepts of Competitive Advantage and Pricing Power

At the core of our investment philosophy is the concept of competitive advantage. We believe companies with competitive advantages are more likely to have superior long-term growth prospects, the opportunity to expand margins, and high and increasing returns on invested capital. These ingredients, coupled with an attractive valuation, typically make for a good stock. One way to measure a company's competitive advantage is to consider the barriers that a new competitor must overcome to enter the market. Another method is to consider how well positioned a company is relative to its customers and suppliers. A company with patents, one with a proprietary product that would be difficult or impossible to recreate or that has a diverse and powerless base of suppliers with long-term contractual relationships with customers is an example of a company that would be very well positioned from a competitive advantage standpoint. In general, we have learned that the best measure of a company's competitive advantage is its ability to raise prices. If we could ask only one question of the many management teams we meet, without a doubt, it would be, "Are you able to raise prices?"

Certain Biotech and Internet Software Stocks Negatively Impacted Returns

Achillion Pharmaceuticals, a biopharmaceutical company with a novel mechanism to treat the Hepatitis C Virus (HCV), suffered a setback when its lead compound was found to create renal toxicity in a Phase I trial. This was clearly a major setback for the company and delayed the program by at least one year. Despite this negative news, we remained enthusiastic because the data from the Phase I trial suggested that the drug's mechanism of action worked. Achillion has a backup compound with a different chemotype that we hope will be metabolized differently than the lead compound and will not create renal toxicity. We believe that the risk/reward profile for the company is solidly in our favor and that if the backup compound successfully gets through the Phase I trial, there is significant upside potential in the stock.

Meanwhile, Adolor was dealt a devastating blow when its leading product in development was found to be unsafe. Entereg, an experimental drug for the treatment of gastrointestinal disease that often accompanies the use of narcotic medications such as codeine, caused increased rates of heart attack, tumors and bone fractures in a year long study of 538 patients taking the drug. This news resulted in a one day 58.72% drop in Adolor's share price and all but ensures that Entereg will never make it to market. We sold Adolor from the Fund entirely.

Another laggard was Japanese company E-Seikatsu. E-Seikatsu offers a web-based subscription service to real estate agents in Japan to help manage rental apartment listings. The Japanese real estate market is quite different than the U.S. market in that the majority of the Japanese population lives in rented apartments instead of owning

their own residential property. Additionally, Japanese real estate agents, unlike their U.S. peers, have been slow to adopt technology and instead, have managed all of their listings using an inefficient and cumbersome paper based system. While we believe E-Seikatsu offers a compelling product that continues to gain traction with real estate agents, a system glitch caused the company to suspend sales for approximately one month. This setback forced E-Seikatsu's management to lower financial guidance in January 2007. We continue to be enthusiastic about the company's long-term prospects despite a 67.67% decline in the share price over the six-month period.

Select Investments in the Financial and Information Technology (IT) Sectors Added to Performance

The financial sector suffered from the dramatic demise of several subprime mortgage lenders during the period. The Fund successfully avoided the subprime space and was able to find attractive investment ideas within the sector. MarketAxess Holdings performed especially well, delivering a 45.60% return. MarketAxess operates an electronic platform for high grade corporate and emerging markets bond trading. We believe that electronic trading will take share in bond markets just as it has in equity markets. With a significant first-mover advantage and a superior product that is liked by both broker-dealers and institutional investors, we feel MarketAxess is in an enviable position. As the company grew during the period, it created significant network effects as the number of broker-dealers and institutional investors on the platform continued to increase. This network effect is a barrier to entry that, in our estimation, will make it very hard for competitors to penetrate the market. For this reason, MarketAxess remains an attractive acquisition target for other companies like the investment banks and Bloomberg, all of whom participate in bond trading. Our investment thesis in the company was confirmed in the six-month period as average monthly volumes traded through the platform increased by approximately 33.7%. We remain optimistic about MarketAxess' long-term prospects but after the stock's strong run we trimmed the Fund's position during the period.

The Fund's investments in the technology sector also performed notably well during the period. Two standouts were Equinix and SAVVIS. Both companies own and operate data centers that provide Internet exchange services to networks, Internet content providers and enterprises. The data center business model has benefited from continued growth in Internet usage driven by the emergence of internet video sites such as YouTube and social media sites such as MySpace. Both companies enjoyed a resurgence after significant overbuilding during the Internet bubble that resulted in many data center owners filing for bankruptcy protection. These bankruptcy filings had the effect of rationalizing the amount of data center space and allowing demand to catch up with supply. Over the past several quarters, Equinix and SAVVIS raised the prices they charge to customers. We believe this is the ultimate sign that they are well positioned and that demand remains healthy. SAVVIS delivered a 65.87% return while Equinix delivered a 22.03% return during the six-month period.

Summary

In conclusion, we would like to reinforce that we are investors in Janus Triton Fund alongside you. We take the responsibility of managing the capital committed to the Fund in a responsible and disciplined manner that we believe will generate consistent long-term results. We look forward to updating you on the Fund's performance in another six months.

Thank you for your investment in Janus Triton Fund.

Janus Capital Management LLC has contractually agreed to waive the Fund's total operating expenses (excluding brokerage commissions, interest, taxes, and extraordinary expenses) to a certain limit until at least March 1, 2008. The expense waiver shown reflects the application of such limit and is detailed in the Statement of Additional Information. Total returns shown include fee waivers, if any, and without such waivers, the Fund's total return would have been lower.

The Fund's expense ratios were determined based on average net assets as of the fiscal year ended October 31, 2006. Detailed information is available in the prospectus. Contractual waivers agreed to by Janus Capital are included under "Net Annual Fund Operating Expenses." All expenses are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

February 28, 2005 is the date used to calculate the since-inception Lipper ranking, which is slightly different from when the Fund began operations since Lipper provides fund rankings as of the last day of the month or the first Thursday after fund inception.

There is no assurance that the investment process will consistently lead to successful investing.

Janus Twenty Fund (unaudited) (closed to new investors)

Ticker: JAVLX

Fund Snapshot

This focused growth fund invests primarily in a core group of 20-30 companies, including many market leaders whose products and services are being used more often every day.

Scott Schoelzel
portfolio manager

Performance Overview

For the six-month period ending April 30, 2007, Janus Twenty Fund returned 11.03%. During the same six-month period, the Russell 1000^® Growth Index returned 8.42% and the S&P 500^® Index, 8.60%.

Needless to say, we continue to be quite pleased with the Fund's performance. When these latest returns, through April 30, 2007, are added to the Fund's past performance, Janus Twenty Fund is solidly in the top performance percentiles compared to its peers for the trailing one-, three-, five- and 10-year periods based on total returns, according to Lipper Analytical Services. The table below depicts the Fund's relative performance in more detail.

Stewardship of the Fund

In addition to the Fund's performance, I personally take great pride in our stewardship of your investments. Janus Twenty Fund's expense ratio remains well below the Lipper Large Cap Growth industry average. As of the most recent fiscal year end, the Fund's annual expense ratio was 0.92% versus the industry average of 1.40%. One of the contributing factors to keeping fund expenses lower than the industry average is the Fund's lower portfolio turnover rate, which results in lower overall trading costs. Janus Twenty Fund's portfolio turnover rate was 41% versus the industry average of 96% as of 10/31/06. Janus Twenty Fund also remains closed to new investors as it has since April of 1999. While there are some compelling arguments to re-open the Fund, and I have little doubt that our expanded research efforts could support a larger find size, I also continue to believe that there is some truth to the old Wall Street adage that "size is the enemy of performance." So, for at least the time being, I prefer to error on the side of conservatism and keep the fund closed to new investors. Finally, in addition to being the Fund's portfolio manager, I remain one of its largest investors, side by side with each one of you.

Key Contributors

Janus Twenty Fund has a number of investments in agriculture and agriculture-related stocks that contributed positively to the Fund's performance. Specifically, our investment in Potash Corporation of Saskatchewan was the single biggest contributor to the Fund's performance during the past six months. Potash is one of the three primary ingredients used to manufacture fertilizer (the other two being phosphate and nitrogen). As the world becomes more industrialized and standards of living have risen, studies show that people who find themselves in an improved economic condition eat better. They consume more meat, poultry and complex foods of all types. Growing and processing more complex foods requires more feed stocks (primarily corn and soy beans), which in turn require higher yields on increasingly tight farmable acreage. We believe Potash is well-positioned with both its potash and phosphate deposits. The company has seen the demand for these mined products increase substantially over the past couple of years. We are often asked if Potash is also an "ethanol" play. The answer is "yes," but ethanol is only one of the positive components of our investment thesis for Potash.

One of the other significant contributors to the Fund's performance was our investment in Syngenta, a Swiss-based company that specializes in the development of seeds and crop-protection products. Syngenta enjoys a very strong market share position in Brazil, which is one of the world's largest agricultural markets; and a competitive position in the U.S. behind Monsanto Corporation, which is also owned in the Fund. The agricultural sector, much like minerals and mining, has historically been very cyclical, and investments in the sector can be volatile and easily misunderstood. I think our research analysts deserve a tremendous amount of credit for the fine work they have done on these investments.

Main Detractor

Whole Foods Market was the biggest detractor to the Fund's performance during the past six months. To be fair, Whole Foods was one of the smaller investments in the Fund and although it was an expensive stock by most financial metrics, we

Janus Growth Funds April 30, 2007 45

Janus Twenty Fund (unaudited)

thought its growth prospects were worthy of a modest investment. Unfortunately, as is often the case with a fast-growing enterprise, it's very difficult to meet the ever-enthusiastic expectations of Wall Street. Whole Foods proved to be no exception. Store openings slowed, food costs rose slightly and sales moderated as the economy softened. Together, the convergence of these three factors caused Whole Foods to fall off our expected growth curve, and as a result the Fund lost money on this investment. Rather than rationalize the bad news as being temporary, I elected to sell the stock. Subsequent to our sale, Whole Foods bought its nearest competitor and I believe the combination of these two enterprises has many potential benefits. We continue to be intrigued with consumers' move toward more natural foods and will be watching their progress.

Outlook Going Forward

The equity markets both here in the U.S. and around the world have been quite strong, but there are signs that the U.S. economy is beginning to slow. Housing in some markets is particularly soft, and the subprime mortgage market has garnered a disproportionate amount of attention, with many pundits claiming this is the first in a series of potential dominos to fall. I am not in that camp. Yes, I think there will be some fallout from the excesses of the recent boom in housing, but our analysis suggests that the economy will be able to absorb these dislocations and after some pause, even the most affected markets should slowly recover.

Outside the U.S., many of the world's economies remain quite strong. In addition to China and India, I believe Latin America and emerging Eastern Europe are particularly robust. I expect some very sharp sell-offs from time to time in these markets, which have historically been faster-growing. I think the sharp sell-offs will spread to the more mature markets. But if there is any lesson to be learned from the past decade, it's that a steady hand is often well-rewarded. I remain optimistic about the global prospects for growth and am confident that our research-centric investment process will continue to find compelling investment opportunities for our investors.

Thank you for you continued confidence and investment in Janus Twenty Fund.

Fund Snapshot

This growth fund focuses on small companies, where there's less Wall Street coverage and more opportunity for a research edge.

Will Bales
portfolio manager

Performance Overview

For the six-month period ending April 30, 2007, the Fund returned 14.48%, outpacing both its primary and secondary benchmarks, the Russell 2000^® Growth Index and the Russell 2000^® Index, which returned 7.42% and 6.86%, respectively.

Economic Overview

With most U.S. equity indexes near all-time highs at the end of the period, I closely monitored several fundamental factors for directional cues. First, despite the weakness in the U.S. housing sector and the associated credit quality issues in the subprime mortgage market, at the end of the period the U.S. unemployment rate was near historic lows, mitigating the impact of the housing slowdown on consumer spending and the overall U.S. economy. I watched the labor market closely for any sign of a slowdown that could impact consumer sentiment and economic growth. Similarly, I monitored the higher-quality prime mortgage market and other areas of consumer lending for any indication of credit quality deterioration. Second, U.S. corporate profit growth experienced double-digit gains for several years, which, combined with strong liquidity from corporate M&A and private equity transactions, supported higher equity valuations. I will continue to watch both the future path of corporate earnings and the overall liquidity in the markets in an effort to determine whether current valuations can be sustained.

Select Consumer and Information Technology (IT) Holdings Aided Performance

I apply a "bottom up" approach in choosing investments. This means that I look at companies one at a time to determine if it is an attractive investment opportunity and if it is consistent with the Fund's investment policies.

For this particular period, Fund performance benefited from successful stock selection in the consumer discretionary and IT sectors, though an overweight to the latter was a detractor from performance Additionally, the Fund's underweight exposure to the financials sector proved fortuitous as consumer lending stocks came under selling pressure early in 2007.

One standout among consumer discretionary holdings was Brazilian online retailer Submarino, which rallied on news that it was being acquired by a larger competitor. Select IT names also aided returns, including employment database provider TALX. This holding with historically recurring revenue streams and strong quarterly results benefited from the recent announcement of its purchase by Equifax.

Industrials Shares Weighed on Performance

On the downside, the Fund suffered from pressure on select names in the industrials sector, where it remained overweight relative to its primary benchmark. Within the industrials sector, IPG Photonics guided to lower-than-expected financial results for the second quarter due to one contract being pulled into the first quarter. I continue to believe the company's laser fabrication technology should earn market share over the long run and use the weakness in its share price to add to the position.

Also within industrials, a relatively new position in non-asset based printing company, InnerWorkings, hurt returns as the stock price suffered. Much of the negative performance of the company's stock came from short positions in the market. I believe the company's competitive advantage is its network of printers and potential clients which should drive positive results.

Outlook

I remain constructive on prospects for the equity market, but caution that uncertainty over the near-term economic outlook could contribute to short-term volatility. Given the recent strength in small cap growth stocks, I will continue to reduce the Fund's positions where I think valuations are less compelling, and use short-term volatility as an opportunity to build positions in the highest-conviction ideas.

Janus Global Life Sciences Fund (unaudited)

Ticker: JAGLX

Fund Snapshot

This fund seeks companies around the world that are dedicated to improving the quality of life for a growing and aging world.

Thomas Malley

portfolio manager

Performance Overview

Equity markets around the globe delivered healthy gains during the period amid continued evidence of strong economic growth and modest inflation. After a brief period of market volatility in late February and early March, stocks rebounded quickly and many indexes posted double-digit gains. While U.S. corporate profit growth showed signs of slowing, robust merger and acquisition (M&A) activity and private equity transactions continued to provide key valuation support to equities in the U.S. and around the world.

Although Janus Global Life Sciences Fund posted a gain of 8.30% during the six month period, it trailed its primary benchmark, the S&P 500^® Index, which advanced 8.60%. The Fund beat the 7.37% return of the Morgan Stanley Capital International World Health Care Index, its secondary benchmark.

Select Biotechnology Stocks Weighed on Returns

Select holdings within the healthcare sector detracted from performance during the period. Nuvelo, a California-based biotech company, declined after its anti-clotting drug Alfimeprase, did not meet primary end points for its Phase III trials. Alfimeprase had generated a high level of enthusiasm in the medical community as a novel agent that promised to be faster, safer and easier to administer than currently available clot-busting drugs. However, despite highly positive Phase II results, the Phase III trials failed to meet their primary endpoints. Given this negative development, I sold the stock at a loss.

Adolor was also stymied by negative news surrounding a new drug offering. In November 2006, the company received notification from the Food and Drug Administration (FDA) that approval for its lead drug Entereg, designed for use in post-surgical complications, would be delayed due to concerns about cardiovascular safety issues that arose from a long term trial. In response, I liquidated the stock.

Achillion Pharmaceuticals, which is developing novel compounds for the treatment of Hepatitis C, also received a setback when its initial drug candidate was discontinued due to adverse effects on the kidney. However, I believe this approach still has merit so I held onto the position, awaiting data from the company's second generation products.

Select Biotechnology and Healthcare Service Stocks Aided Returns

The Fund also experienced its share of success stories during the semiannual period. Advanced Magnetics was our top performer. The company posted a sharp gain fueled by positive data for its drug Ferumoxytol, a potential best in class iron replacement therapeutic for chronic kidney disease patients.

I was also pleased with the performance of Medco Health Solutions, one of the country's largest prescription drug benefit managers. Medco advanced during the period on better-than-expected earnings that stemmed from an increase in generic drug utilization and better penetration of specialty biotechnology products.

The Fund also benefited when one of our venture capital investments, Cougar Biotechnology, went public at a significant premium to our initial investment. Cougar has three novel cancer agents in clinical development that I believe could drive further upside potential.

Looking Ahead

The outlook at this juncture is cautiously optimistic. Healthcare spending trends will be carefully watched as there have been signs that Congress may look to restrain the growth of Medicare spending. At the same time, my team and I feel that any changes at the companies in which we invest will be manageable. We are confident in the names we own and feel that the healthcare sector's recent underperformance could be due for a turnaround. Regardless, we will continue to seek investments within the healthcare arena that we feel represent the sector's best opportunities.

In closing, I recently announced that I will retire from my portfolio manager responsibilities for the Janus Global Life Sciences Fund, effective May 1, 2007. Andy Acker will become the portfolio manager of the Fund.

After working closely with Andy over the past eight years researching and investing in leading health care companies, I have high confidence in his ability to successfully manage the Fund. With his 11 years of experience, educational background in business and biochemistry and intuition about the markets, he is ideally suited to take over the reins.

I want to thank you for all your support over the years. It has been an honor to have worked on your behalf.

Janus Global Technology Fund (unaudited)

Ticker: JAGTX

Fund Snapshot

This fund pursues forward-thinking companies around the globe that are advancing the frontiers of technology in profitable ways.

Team Based Approach
Led by Brad Slingerlend
and Barney Wilson

Performance Overview

During the six months ended April 30, 2007, Janus Global Technology Fund advanced 12.51%. By comparison, the Fund's benchmarks, the Morgan Stanley Capital International (MSCI) World Information Technology Index and the S&P 500^® Index returned 7.85% and 8.60%, respectively.

Investment Strategy

Janus Global Technology Fund's strategy is to seek long-term growth of capital. The Janus team of technology analysts and I look for high quality and innovative technology companies that are growing earnings and cash flow in excess of market expectations. To do this, we scour the globe to find what we believe are the best investment opportunities for the Fund. While investing in the technology sector can be more volatile than a broader market index, we believe the sector can provide an excellent area in which to seek attractive investment returns if one can tolerate the volatility.

As was recently announced, my very capable co-manager, Brad Slingerlend, elected to leave Janus to pursue other opportunities. I want to thank Brad for his many contributions to the Janus technology team over the years and wish him well in his new endeavors. As such, I have assumed responsibility as sole portfolio manager on the Fund and I plan to maintain the current investment strategy. The analysts and I will continue to employ the same in-depth fundamental analysis that is the hallmark of Janus. I intend to maintain the approach of keeping the portfolio close to the Janus analysts' views on stocks and intend to maintain over 90% of the portfolio in "buy" and "strong buy" rated stocks, which we did during the period. In addition, I plan to continue to construct a portfolio that is diversified across subsectors of tech, geographies, market capitalizations and valuation ranges.

The Fund invested in a few exciting themes during the period. One such theme included the increasing interactivity of the Internet as it undergoes a second wave of innovation. Driven by broadband penetration levels reaching above 40% in many developed countries, we are starting to see new and compelling ways to utilize the Internet. Companies like YouTube, recently purchased by Google, are changing the way consumers view their entertainment options. This broader sector theme is borne out in the Fund's investments including Akamai Technologies, Yahoo!, Google, Equinix and Juniper Networks.

Another exciting theme included the globalization of technology development and services. The Janus team of technology analysts visited hundreds of companies around the world during the period. They returned enthusiastic about the rapidly developing skill sets, such as information technology (IT) services and low-cost hardware manufacturing, in Asia. For example, longtime holding Hon Hai Precision Industry, based in Taiwan, has become the largest contract manufacturer in the world and continues to grow rapidly. In India, we think the large and growing pool of skilled software engineers helped contribute to gains in our investments in Infosys Technologies and Satyam Computer. As innovation continues to evolve in these emerging markets we continue to seek what we believe are the best growth technology companies at reasonable valuations.

Contributors to Fund Performance

Select holdings within industrials and consumer discretionary made positive contributions to performance during the time period.

Within industrials, solar company Suntech Power posted significant gains as it was able to maintain high rates of revenue and earnings growth. Another solar company, SunPower Corporation, also contributed to performance. We are quite positive on the multiyear outlook for the leading manufacturers of solar cells and the related food chain. As such, a number of holdings in the Fund are exposed to the secular trend of increasing the use of solar power to meet worldwide energy needs.

Within the consumer discretionary sector, Sony performed well during the time period. Based on our proprietary research, we have increased conviction in the company's ability to achieve manufacturing leverage by driving down costs. Our analysis contradicts Wall Street's skeptical view of Sony's ability to achieve operating margin goals. Furthermore, we are constructive on the flat panel TV market, which we think will likely benefit Sony's electronics market.

Detractors from Performance

While select holdings within the IT semiconductors sub-sector made a positive contribution to performance, certain

semiconductor holdings declined in the quarter. Silicon-On-Insulator Technologies (SOITEC), a French-based semiconductor company, was the largest detractor to performance. The company manufactures a layer of insulation that sits on top of a wafer and allows a hot processor to run cooler. Our view is that unit sales remain satisfactory and there are no competitive threats to the technology. While we slightly trimmed the position, we held onto the stock.

SanDisk, a leader in the flash memory market, was another detractor to performance. The company reported in its recent quarter that prices for flash memory had declined more than expected, which negatively impacted margins. While remaining constructive on the outlook for flash memory usage in devices like MP3 players and digital cameras, we sold the stock to reflect the uncertain price environment.

Looking Ahead

The Janus team of technology analysts will continue to focus on anticipating change. What consumer electronic products will be multiyear successes? What business-related technology products will provide more value at lower cost? Where is innovation happening? Which vendors are falling behind and who is gaining share? These are just some of the questions we try to answer before the rest of the investment community. Leveraging the strong grassroots research foundation of Janus, we will utilize Janus' global research platform to uncover what we believe are the best companies with the most upside potential for our shareholders.

Thank you for your investment in Janus Global Technology Fund.

Notes to Financial Statements (unaudited)

The following section describes the organization and significant accounting policies and provides more detailed information about the schedules and tables that appear throughout this report. In addition, the Notes to Financial Statements explain the methods used in preparing and presenting this report.

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Janus Fund, Janus Enterprise Fund, Janus Orion Fund, Janus Research Fund (formerly named Janus Mercury Fund), Janus Triton Fund, Janus Twenty Fund, Janus Venture Fund, Janus Global Life Sciences Fund and Janus Global Technology Fund (collectively the "Funds" and individually a "Fund") are series funds. The Funds are part of Janus Investment Fund (the "Trust"), which was organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the "1940 Act") as an open-end management investment company. The Trust has thirty funds. Each of the Funds in this report is classified as diversified as defined in the 1940 Act, with the exception of Janus Orion Fund and Janus Twenty Fund, which are classified as nondiversified. The Funds are no-load investments.

The following accounting policies have been consistently followed by the Funds and are in conformity with accounting principles generally accepted in the United States of America in the investment company industry.

Investment Valuation

Securities are valued at the last sales price or the official closing price for securities traded on a principal securities exchange (U.S. or foreign) and on the NASDAQ National Market. Securities traded on over-the-counter markets and listed securities for which no sales are reported are valued at the latest bid price (or yield equivalent thereof) obtained from one or more dealers transacting in a market for such securities or by a pricing service approved by the Funds' Trustees. Short-term securities with maturities of 60 days or less may be valued at amortized cost, which approximates market value. Debt securities with a remaining maturity of greater than 60 days are valued in accordance with the evaluated bid price supplied by the pricing service. The evaluated bid price supplied by the pricing service is an evaluation that reflects such factors as security prices, yields, maturities and ratings. Foreign securities and currencies are converted to U.S. dollars using the applicable exchange rate in effect as of the daily close of the New York Stock Exchange ("NYSE"). When market quotations are not readily available or deemed unreliable, or events or circumstances that may affect the value of portfolio securities held by the Funds are identified between the closing of their principal markets and the time the net asset value ("NAV") is determined, securities may be valued at fair value as determined in good faith under procedures established by and under the supervision of the Funds' Trustees. The Funds may use a systematic fair valuation model provided by an independent third party to value international equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the NYSE.

Investment Transactions and Investment Income

Investment transactions are accounted for as of the date purchased or sold (trade date). Dividend income is recorded on the ex-dividend date. Certain dividends from foreign securities will be recorded as soon as the Trust is informed of the dividend if such information is obtained subsequent to the ex-dividend date and may be subject to withholding taxes in these jurisdictions. Interest income is recorded on the accrual basis and includes amortization of premiums and accretion of discounts. Gains and losses are determined on the identified cost basis, which is the same basis used for federal income tax purposes.

Expenses

Each Fund bears expenses incurred specifically on its behalf as well as a portion of general expenses, which may be allocated pro rata to each of the Funds in the Trust.

Securities Lending

Under procedures adopted by the Trustees, the Funds may lend securities to qualified parties (typically brokers or other financial institutions) who need to borrow securities in order to complete certain transactions such as covering short sales, avoiding failures to deliver securities or completing arbitrage activities. The Funds may seek to earn additional income through securities lending. There is the risk of delay in recovering a loaned security or the risk of loss in collateral rights if the borrower fails financially. In addition, Janus Capital Management LLC ("Janus Capital") makes efforts to balance the benefits and risks from granting such loans.

The Funds do not have the right to vote on securities while they are being lent; however, the Funds may attempt to call back the loan and vote the proxy. All loans will be continuously secured by collateral which may consist of cash, U.S. Government securities, domestic and foreign short-term debt instruments, letters of credit or such other collateral permitted by the Securities and Exchange Commission ("SEC"). Cash collateral may be invested in affiliated money market funds or other accounts advised by Janus Capital to the extent consistent with exemptive relief obtained from the SEC or as permitted by the 1940 Act and rules promulgated thereunder. Cash collateral may also be invested in unaffiliated money market funds or other accounts advised by Janus Capital to the extent consistent with exemptive relief obtained from the SEC or as permitted by the 1940 Act and rules promulgated thereunder. Cash collateral may also be invested in unaffiliated money market funds or other accounts.

State Street Bank and Trust Company (the "Lending Agent") may also invest the cash collateral in the State Street Navigator Securities Lending Prime Portfolio or investments in

unaffiliated money market funds or accounts, mutually agreed to by the Funds and the Lending Agent, that comply with Rule 2a-7 of the 1940 Act relating to money market funds.

Additionally, Janus Fund, Janus Enterprise Fund, Janus Orion Fund, Janus Research Fund, Janus Global Life Sciences Fund and Janus Global Technology Fund invested $43,116,592, $745,249, $4,584,991, $17,455,693, $2,038,343 and $511,665, respectively, of the cash collateral in U.S. Treasury Notes/Bonds.

The value of the collateral must be at least 102% of the market value of the loaned securities that are denominated in U.S. dollars and 105% of the market value of the loaned securities that are not denominated in U.S. dollars. Loaned securities and related collateral are marked-to-market each business day based upon the market value of the respective securities at the close of business, employing the most recent available pricing information. Collateral levels are then adjusted based on this mark-to-market evaluation.

The borrower pays fees at the Funds' direction to its Lending Agent. The Lending Agent may retain a portion of the interest earned. The cash collateral invested by the Lending Agent is disclosed in the Schedule of Investments. The lending fees and the Funds' portion of the interest income earned on cash collateral are included on the Statement of Operations (if applicable).

During the six-month ended April 30, 2007, there were no securities lending arrangements for Janus Triton Fund.

Interfund Lending

Pursuant to an exemptive order received from the SEC, each Fund may be party to an interfund lending agreement between the Fund and other Janus Capital sponsored mutual funds, which permits it to borrow or lend cash at a rate beneficial to both the borrowing and lending funds. Outstanding borrowings from all sources totaling 10% or more of a borrowing Fund's total assets must be collateralized at 102% of the outstanding principal value of the loan; loans of less than 10% may be unsecured. During the six-month period ended April 30, 2007, there were no outstanding interfund borrowing or lending arrangements for the Funds.

Short Sales

The Funds may engage in "short sales against the box." Short sales against the box involve selling either a security that the Fund owns, or a security equivalent in kind and amount to the security sold short that the Fund has the right to obtain, for delivery at a specified date in the future. The Fund may enter into a short sale against the box to hedge against anticipated declines in the market price of portfolio securities. If the value of the securities sold short increases prior to the scheduled delivery date, the Fund loses the opportunity to participate in the gain.

The Funds may also engage in "naked" (uncovered) short sales. Naked short sales involve a Fund selling a security it does not own to a purchaser at a specified price. To complete the transaction, the Fund must borrow the security to deliver it to the purchaser and buy that same security in the market to return it to the lender. Although the potential for gain is limited to the difference between the price at which the Fund sold the security short and the cost of borrowing the security, its potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security. There is no assurance that the Fund will be able to close out a short position at a particular time or at an acceptable price. A gain or a loss will be recognized upon termination of a short sale. There is no limit on the size of any loss that a Fund may recognize upon termination of a short sale. Short sales held by the Fund are fully collateralized by other securities, which are denoted in the accompanying Schedule of Investments (if applicable). As of April 30, 2007, Janus Global Technology Fund was invested in short sales.

Forward Currency Transactions

92 Janus Growth Funds April 30, 2007

A forward currency exchange contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated rate. The gain or loss arising from the difference between the U.S. dollar cost of the original contract and the value of the foreign currency in U.S. dollars upon closing a contract is included in "Net realized gain/(loss) from foreign currency transactions" on the Statement of Operations (if applicable).

Forward currency contracts held by the Funds are fully collateralized by other securities, which are denoted in the accompanying Schedule of Investments (if applicable). The collateral is evaluated daily to ensure its market value equals or exceeds the current market value of the corresponding forward currency contracts.

As of April 30, 2007, Janus Fund, Janus Orion Fund, Janus Research Fund, Janus Global Life Sciences Fund and Janus Global Technology Fund were invested in forward currency transactions.

Futures Contracts

The Funds may enter into futures contracts. The Funds intend to use such derivative instruments to hedge or protect from adverse movements in securities prices, currency rates or interest rates. The use of futures contracts may involve risks such as the possibility of illiquid markets or imperfect correlation between the value of the contracts and the underlying securities, or that the counterparty will fail to perform its obligations.

Futures contracts are marked-to-market daily, and the daily variation margin is recorded as a receivable or payable on the Statement of Assets and Liabilities (if applicable). When a contract is closed, a realized gain or loss is recorded on the Statement of Operations (if applicable), equal to the difference between the opening and closing value of the contract. Generally, futures contracts are marked-to-market (i.e., treated as realized and subject to distribution) for federal income tax purposes at fiscal year-end. Securities designated as collateral for market value on futures contracts are noted in the Schedule of Investments (if applicable). Such collateral is in the possession of the Funds' custodian.

As of April 30, 2007, the Funds were not invested in futures contracts.

Foreign Currency Translations

The Funds do not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held at the date of the financial statements. Net unrealized appreciation or depreciation on investments and foreign currency translation arise from changes in the value of assets and liabilities, including investments in securities held at the date of the financial statements, resulting from changes in the exchange rates and changes in market prices of securities held.

Currency gains and losses are also calculated on payables and receivables that are denominated in foreign currencies. The payables and receivables are generally related to security transactions and income.

Foreign currency-denominated assets and forward currency contracts may involve more risks than domestic transactions, including currency risk, political and economic risk, regulatory risk and market risk. Risks may arise from the potential inability of a counterparty to meet the terms of a contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar.

Options Contracts

When an option is written, the Fund receives a premium and becomes obligated to sell or purchase the underlying security at a fixed price, upon exercise of the option. In writing an option, the Fund bears the market risk of an unfavorable change in the price of the security underlying the written option. Exercise of an option written by the Fund could result in the Fund buying or selling a security at a price different from the current market value.

When an option is exercised, the proceeds on sales for a written call option, the purchase cost for a written put option, or the cost of the security for a purchased put or call option is adjusted by the amount of premium received or paid.

Holdings designated to cover outstanding written options are noted in the Schedule of Investments (if applicable). Options written are reported as a liability on the Statement of Assets and Liabilities (if applicable). Realized gains and losses are reported on the Statement of Operations (if applicable). The following Funds recognized realized gains or losses from written options during the six-month period ended April 30, 2007.

Janus Research Fund⁽¹⁾		5,033,932
Janus Triton Fund		–
Speciality Growth
Janus Global Technology Fund		647,914

(1) Formerly named Janus Mercury Fund.

The risk in writing a call option is that a Fund gives up the opportunity for profit if the market price of the security increases and the option is exercised. The risk in writing a put option is that a Fund may incur a loss if the market price of the security decreases and the option is exercised. The risk in buying an option is that a Fund pays a premium whether or not the option is exercised. The use of such instruments may involve certain additional risks as a result of unanticipated movement in the market. A lack of correlation between the value of an instrument underlying an option and the asset being hedged, or unexpected adverse price movements, could render a Fund's hedging strategy unsuccessful. In addition, there can be no assurance that a liquid secondary market will exist for any option purchased or sold. There is no limit to the loss that a Funds may recognize due to written call options.

When-issued Securities

The Funds may purchase or sell securities on a when-issued or forward commitment basis. The price of the underlying securities and date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Losses may arise due to changes in the market value of the securities or from the inability of counterparties to meet the terms of the contract. In connection with such purchases, the Fund may hold liquid assets as collateral with the Fund's custodian sufficient to cover the purchase price. As of April 30, 2007, there were no Funds invested in when-issued securities.

Equity-Linked Structured Notes

The Funds may invest in equity-linked structured notes. Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or nonregistered form. An investment in equity-linked structured notes creates exposure to the credit risk of the issuing financial institution, as well as to the market risk of the underlying securities. There is no guaranteed return of principal with these securities and the appreciation potential of these securities may be limited by a maximum payment or call right. In certain cases, equity-linked structured notes may be more volatile and less liquid than less complex securities or other types of fixed-income securities. Such securities may exhibit price behavior that does not correlate with other fixed-income securities. As of April 30, 2007, Janus Global Technology Fund was invested in equity-linked structured notes.

Initial Public Offerings

The Funds may invest in initial public offerings ("IPOs"). IPOs and other investment techniques may have a magnified performance impact on a fund with a small asset base. A Fund may not experience similar performance as its assets grow.

Restricted Security Transactions

Restricted securities held by a Fund may not be sold except in exempt transactions or in a public offering registered under the Securities Act of 1933. The risk of investing in such securities is generally greater than the risk of investing in the securities of widely held, publicly traded companies. Lack of a secondary market and resale restrictions may result in the inability of a Fund to sell a security at a fair price and may substantially delay the sale of the security. In addition, these securities may exhibit greater price volatility than securities for which secondary markets exist.

Restricted Cash

As of April 30, 2007, Janus Fund had restricted cash in the amount of $7,493,850. The restricted cash represents funds in relation to options contracts invested by Janus Fund at April 30, 2007. The restricted cash is held at the Fund's

94 Janus Growth Funds April 30, 2007

custodian, State Street Bank and Trust Company. The carrying value of the restricted cash approximates fair value.

Dividend Distributions

Each Fund generally declares and distributes dividends of net investment income and capital gains (if any) annually. The majority of dividends and capital gains distributions from a Fund will be automatically reinvested into additional shares of that Fund, based on the discretion of the shareholder.

Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

Federal Income Taxes

No provision for income taxes is included in the accompanying financial statements, as the Funds intend to distribute to shareholders all taxable investment income and realized gains and otherwise comply with Subchapter M of the Internal Revenue Code applicable to regulated investment companies.

New Accounting Pronouncements

In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes – an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Funds, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. A calendar year open-end or closed-end fund would implement the interpretation no later than June 29, 2007 (the last business day of the semi-annual reporting period) and will also apply to all open tax years as of the date of effectiveness. Management has recently begun to evaluate the application of the Interpretation to the Funds, and is not in a position at this time to estimate the significance of its impact, if any, on the Funds' financial statements.

In September 2006, the SEC issued Staff Accounting Bulletin ("SAB") No. 108 "Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements" (SAB 108). SAB 108 requires that public companies utilize a "dual approach" to assessing the quantitative effects of financial misstatements. This dual approach includes both an income statement focused assessment and a balance sheet focused assessment. The guidance in SAB 108 must be applied to annual financial statements for fiscal years ending after November 15, 2006. Management is currently assessing the impact of adopting SAB 108 on each Fund's financial position or results of operations.

2. INVESTMENT ADVISORY AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

Each Fund pays a monthly advisory fee to Janus Capital based upon average daily net assets and calculated at the annual rate of 0.64%.

For Janus Research Fund, the investment advisory fee is determined by calculating a base fee and applying a performance adjustment. The base fee rate is the same as the investment advisory fee rate shown in the previous paragraph. The performance adjustment either increases or decreases the base fee depending on how well the Fund has performed relative to its benchmark, as shown below:

Fund				Benchmark Index
Janus Research Fund⁽¹⁾				Russell 1000 Growth^® Index

(1) Formerly named Janus Mercury Fund.

Only the base fee rate applied until February 2007 for Janus Research Fund, at which time the calculation of the performance adjustment is applied as follows:

(Investment Advisory Fee = Base Fee +/- Performance Adjustment).

The investment advisory fee paid to Janus Capital by Janus Research Fund consists of two components: (i) a base fee calculated by applying the contractual fixed-rate of the advisory fee to the Fund's average daily net assets during the previous month ("Base Fee"), plus or minus (ii) a performance-fee adjustment ("Performance Adjustment") calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund's average daily net assets during the applicable performance measurement period.

The performance measurement period generally is the previous 36 months, although no Performance Adjustment will be made until the Fund's performance-based fee structure has been in effect for at least 12 months. When the Fund's performance-based fee structure has been in effect for at least 12 months, but less than 36 months, the performance measurement period will be equal to the time that has elapsed since the performance-based fee structure took effect. As noted above, any Performance Adjustment began February 2007 for Janus Research Fund. No Performance Adjustment will be applied unless the difference between the Fund's investment performance and the investment record of the Fund's benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. Because the Performance Adjustment is tied to the Fund's relative performance to its benchmark index (and not its absolute performance), the Performance Adjustment could increase Janus Capital's fee even if the Fund's shares lose value during the performance measurement period and could decrease Janus Capital's fee even if the Fund's shares increase in value during the performance measurement period. For purposes of computing the Base Fee and the Performance Adjustment, net assets will be averaged over different periods

Janus Growth Funds April 30, 2007 95

Notes to Financial Statements (unaudited) (continued)

(average daily net assets during the previous month for the Base Fee, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of the Fund is calculated net of expenses whereas the Fund's benchmark index does not have any expenses. Reinvestment of dividends and distributions are included in calculating both the performance of the Fund and the Fund's benchmark index. The Base Fee is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued evenly each day throughout the month. The investment fee is paid monthly in arrears.

The Fund's prospectus and statement of additional information contains additional information about performance-based fees. The amount shown as Advisory fees on the Statement of Operations reflects the base fee plus/minus any performance adjustment.

Until at least March 1, 2008, provided that Janus Capital remains investment adviser to the Funds, Janus Capital has agreed to reimburse Janus Triton Fund by the amount, if any, that such Fund's normal operating expenses in any fiscal year, including the investment advisory fee, but excluding brokerage commissions, interest, taxes and extraordinary expenses, exceed the annual rate of 1.25%. If applicable, amounts reimbursed to the Fund by Janus Capital are disclosed as Excess Expense Reimbursement on the Statement of Operations.

Each of the Funds pays Janus Services LLC ("Janus Services"), a wholly-owned subsidiary of Janus Capital, an asset-weighted average annual fee based on the proportion of each Fund's total net assets sold directly and the proportion of each Fund's net assets sold through financial intermediaries. The applicable fee rates are 0.16% of net assets on the proportion of assets sold directly and 0.21% on the proportion of assets sold through intermediaries. In addition, Janus Services receives $4.00 per open shareholder account (excluding Janus Twenty Fund and Janus Venture Fund) for transfer agent services.

During the six-month period ended April 30, 2007, Janus Services reimbursed the following Funds as a result of dilutions caused by incorrectly processed shareholder activity as indicated in the table below.

For the six-month period ended April 30, 2007, Janus Capital assumed $18,145 of legal, consulting and Trustee costs and fees incurred by the funds in Janus Investment Fund, Janus Aspen Series and Janus Adviser Series (the "Portfolios") in connection with the regulatory and civil litigation matters discussed in Note 7. These non-recurring costs were allocated to all Portfolios, based upon the Portfolios' respective net assets as of July 31, 2004. No fees were allocated to Janus Global Research Fund, Janus Triton Fund and the Janus Smart Portfolios as the funds commenced operations after July 31, 2004. Additionally, all future non-recurring costs will be allocated to all Portfolios based upon the Portfolios' respective net assets on July 31, 2004. These non-recurring costs and costs assumed by Janus Capital are shown on the Statement of Operations.

Effective January 1, 2006, the Board of Trustees adopted a deferred compensation plan (the "Plan") for independent Trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from the Funds. All deferred fees are credited to an account established in the name of the Trustees. The amounts credited to the account then increase or decrease, as the case may be, in accordance with the performance of one or more of the Janus funds that are selected by the Trustees. The account balance continues to fluctuate in accordance with the performance of the selected fund or funds until final payment of all amounts credited to the account. Trustees are allowed to change their designation of mutual funds from time to time. Amounts will be deferred until distributed in accordance with the Plan. No deferred fees were paid to any Trustee under the Plan during the six-month period ended April 30, 2007.

96 Janus Growth Funds April 30, 2007

Certain officers of the Funds may also be officers and/or directors of Janus Capital. Such officers receive no compensation from the Funds, except for the Funds' Chief Compliance Officer. Effective January 1, 2006, the Funds began reimbursing the adviser for a portion of the compensation paid to the Chief Compliance Officer of the Funds. Total compensation of $59,081 was paid by the Trust during the six-month period ended April 30, 2007. The Funds' portion is reported as part of "Other Expenses" on the Statement of Operations.

The Funds' expenses may be reduced by expense offsets from an unaffiliated custodian and/or transfer agent. Such offsets are included in Expense and Fee Offsets on the Statement of Operations. The transfer agent fee offsets received during the period reduce Transfer Agent Fees and Expenses. Custodian offsets received reduce Custodian Fees. The Funds could have employed the assets used by the custodian and/or transfer agent to produce income if they had not entered into an expense offset arrangement.

A 2.00% redemption fee may be imposed on shares of Janus Global Life Sciences Fund and Janus Global Technology Fund held for three months or less. Effective with purchases on and after May 15, 2007, a 2% redemption fee may be imposed on shares held for 90 days or less. This fee is paid to the Funds rather than Janus Capital, and is designed to deter excessive short-term trading and to offset the brokerage commissions, market impact, and other costs associated with changes in the Funds' asset levels and cash flow due to short-term money movements in and out of the Funds. The redemption fee is accounted for as an addition to Paid-in Capital. Total redemption fees received by Janus Global Life Sciences Fund and Janus Global Technology Fund were $33,029 and $29,260, respectively, for the six-month period ended April 30, 2007.

The Funds may invest in money market funds, including funds managed by Janus Capital. During the six-month period ended April 30, 2007, the following Funds recorded distributions from affiliated investment companies as affiliated dividend income, and had the following affiliated purchases and sales:

Accumulated capital losses noted below represent net capital loss carryovers, as of October 31, 2006, that may be available to offset future realized capital gains and thereby reduce future taxable gains distributions. The table below shows the expiration dates of the carryovers.

The capital loss carryforward in Janus Orion Fund is subject to annual limitations under applicable tax laws and may expire unused as a result of the Janus Olympus Fund acquisition during the current year. Due to these limitations, $43,227,226 of the carryforward will not be available for use. As a result, this amount has been reclassified to paid-in-capital.

6. FUND ACQUISITIONS

On October 31, 2006, Janus Orion Fund acquired all of the net assets of Janus Olympus Fund pursuant to a plan of reorganization approved by the Trustees of Janus Investment Fund. The reorganization was accomplished by a tax-free exchange of shares of Janus Olympus Fund in the amount of 63,425,023 shares (valued at $2,124,928,540) for the 223,865,207 shares of Janus Orion Fund, including $411,818,312 of unrealized appreciation. The aggregate net assets of Janus Orion Fund and Janus Olympus Fund immediately before the reorganization were $1,119,129,656 and $2,124,928,540, respectively. The aggregate net assets immediately after the reorganization were $3,244,058,196.

7. PENDING LEGAL MATTERS

In the fall of 2003, the Securities and Exchange Commission ("SEC"), the Office of the New York State Attorney General ("NYAG"), the Colorado Attorney General ("COAG"), and the Colorado Division of Securities ("CDS") announced that they were investigating alleged frequent trading practices in the mutual fund industry. On August 18, 2004, Janus Capital announced that it had reached final settlements with the SEC, the NYAG, the COAG, and the CDS related to such regulators' investigations into Janus Capital's frequent trading arrangements.

A number of civil lawsuits were brought against Janus Capital and certain of its affiliates, the Janus funds, and related entities and individuals based on allegations similar to those announced by the above regulators and were filed in several state and federal jurisdictions. Such lawsuits alleged a variety of theories for recovery including, but not limited to, the federal securities laws, other federal statutes (including ERISA), and various common law doctrines. The Judicial Panel on Multidistrict Litigation transferred these actions to the U.S. District Court for the District of Maryland (the "Court") for coordinated proceedings. On September 29, 2004, five consolidated amended complaints were filed with the Court that generally include: (i) claims by a putative class of investors in certain Janus funds asserting claims on behalf of the investor class (Marini, et al. v. Janus Investment Fund, et al., U.S. District Court, District of Maryland, Case No. 04-CV-00497); (ii) derivative claims by investors in certain Janus funds ostensibly on behalf of such funds (Steinberg et al. v. Janus Capital Management, LLC et al., U.S. District Court, District of Maryland, Case No. 04-CV-00518); (iii) claims on behalf of participants in the Janus 401(k) plan (Wangberger v. Janus Capital Group Inc., 401(k) Advisory Committee, et al., U.S. District Court, District of Maryland, Case No. JFM-05-2711); (iv) claims brought on behalf of shareholders of Janus Capital Group Inc. ("JCGI") on a derivative basis against the Board of Directors of JCGI (Chasen v. Whiston, et al., U.S. District Court, District of Maryland, Case No. 04-MD-00855); and (v) claims by a putative class of shareholders of JCGI asserting claims on behalf of the shareholders (Wiggins, et al. v. Janus Capital Group, Inc., et al., U.S. District Court, District of Maryland, Case No. 04-CV-00818). Each of the five complaints initially named JCGI and/or Janus Capital as a defendant. In addition, the following were also named as defendants in one or more of the

100 Janus Growth Funds April 30, 2007

actions: Janus Investment Fund ("JIF"), Janus Aspen Series ("JAS"), Janus Adviser Series ("JAD"), Janus Distributors LLC, Enhanced Investment Technologies, LLC ("INTECH"), Bay Isle Financial LLC ("Bay Isle"), Perkins, Wolf, McDonnell and Company, LLC ("Perkins"), the Advisory Committee of the Janus 401(k) plan, and the current or former directors of JCGI.

On August 25, 2005, the Court entered orders dismissing most of the claims asserted against Janus Capital and its affiliates by fund investors in the Marini and Steinberg cases (actions (i) and (ii) above) except certain claims under Section 10(b) of the Securities Exchange Act of 1934 and under Section 36(b) of the Investment Company Act of 1940, as amended (the "1940 Act"). On August 15, 2006, the Wangberger complaint in the 401(k) plan class action (action (iii) above) was dismissed by the district court with prejudice; the plaintiff appealed that dismissal decision to the United States Court of Appeals for the Fourth Circuit. That appeal is still pending. The Court also dismissed the Chasen lawsuit (action (iv) above) against JCGI's Board of Directors without leave to amend. Finally, a Motion to Dismiss the Wiggins suit (action (v) above) was granted and the matter was dismissed in May 2007.

In addition to the lawsuits described above, the Auditor of the State of West Virginia ("Auditor"), in his capacity as securities commissioner, has initiated administrative proceedings against many of the defendants in the market timing cases (including JCGI and Janus Capital) and, as a part of its relief, is seeking disgorgement and other monetary relief based on similar market timing allegations (In the Matter of Janus Capital Group Inc. et al., Before the Securities Commissioner, State of West Virginia, Summary Order No. 05-1320). The respondents in these proceedings collectively sought a Writ of Prohibition in state court, which was denied. Their subsequent Petition for Appeal was also denied. Consequently, in September 2006, JCGI and Janus Capital filed their answer to the Auditor's summary order instituting proceedings and requested a hearing. A hearing is currently scheduled for June 28, 2007. JCGI and Janus Capital, as well as other similarly situated defendants, continue to challenge the statutory authority of the Auditor to bring such an action.

In addition to the "market timing" actions described above, Janus Capital was a defendant in a consolidated lawsuit in the U.S. District Court for the District of Colorado challenging the investment advisory fees charged by Janus Capital to certain Janus funds (Walter Sins, et al. v. Janus Capital Management LLC, U.S. District Court, District of Colorado, Case No. 04-CV-01647-WDM-MEH; Michael Fleisher, et al. v. Janus Capital Management, LLC, 04-CV-02395-MSK-CBS). The action was filed in 2004 by fund investors asserting breach of fiduciary duty under Section 36(b) of the 1940 Act. The plaintiffs sought declaratory and injunctive relief and an unspecified amount of damages. In April 2007, the parties in the litigation jointly filed a Stipulation Regarding Dismissal of Claims With Prejudice ("Stipulation of Dismissal"), and on May 2, 2007, the Colorado District Court approved the Stipulation of Dismissal and dismissed the case.

In 2001, Janus Capital's predecessor was also named as a defendant in a class action suit in the U.S. District Court for the Southern District of New York, alleging that certain underwriting firms and institutional investors violated antitrust laws in connection with initial public offerings (Pfeiffer v. Credit Suisse First Boston aka In re Initial Public Offering Antitrust Litigation, U.S. District Court, Southern District of New York, Case No. 01-CV-2014). The U.S. District Court dismissed the plaintiff's antitrust claims in November 2003; however, the U.S. Court of Appeals vacated that decision and remanded it for further proceedings. In March 2006, the defendants, including Janus Capital, filed a Petition for a Writ of Certiorari with the U.S. Supreme Court to review the decision of the U.S. Court of Appeals. The U.S. Supreme Court granted the Petition for a Writ of Certiorari and heard argument on the matter on March 27, 2007. The parties are now awaiting a decision on the matter from the U.S. Supreme Court.

Additional lawsuits may be filed against certain of the Janus funds, Janus Capital, and related parties in the future. Janus Capital does not currently believe that these pending actions will materially affect its ability to continue providing services it has agreed to provide to the Janus funds.

Approval of Advisory Agreements During the Period

The Trustees of Janus Investment Fund, more than eighty-five percent of whom have never been affiliated with the adviser ("Independent Trustees"), oversee the management of each of the Funds and, as required by law, determine annually whether to continue the investment advisory agreement for each Fund and the subadvisory agreements for the three Funds that utilize subadvisers.

In connection with their most recent consideration of those agreements for each of the Funds, the Trustees received and reviewed a substantial amount of information provided by Janus Capital and the respective subadvisers in response to requests of the Independent Trustees and their independent legal counsel. They also received and reviewed a considerable amount of information and analysis provided to the Trustees by their independent fee consultant. Throughout their consideration of the agreements the Independent Trustees were advised by their independent legal counsel. The Independent Trustees met on two separate occasions with management to consider the agreements, and at each of those meetings they also met separately in executive session with their independent legal counsel.

At a meeting held on December 20, 2006, based on their evaluation of the information provided by Janus Capital, the subadvisers and the independent fee consultant and other information, the Trustees determined that the overall arrangements between each Fund and Janus Capital were fair and reasonable in light of the nature, extent and quality of the services provided by Janus Capital, its affiliates and the subadvisers, the fees charged for those services, and other matters that the Trustees considered relevant in the exercise of their business judgment. At that meeting all of the Trustees unanimously approved the continuation of the investment advisory agreement for each Fund, and the subadvisory agreement for each subadvised Fund, for the period from February 1, 2007 through February 1, 2008 (January 1, 2007 through January 1, 2008 for INTECH Risk-Managed Stock Fund and Janus Global Research Fund), subject to earlier termination as provided in each agreement.

In considering the continuation of those agreements, the Trustees reviewed and analyzed various factors that they determined were relevant, including the factors described below, none of which by itself was considered dispositive. However, the material factors and conclusions that formed the basis for the Trustees' determination to approve the continuation of the agreements are discussed separately below.

Nature, Extent and Quality of Services

The Trustees reviewed the nature, extent and quality of the services provided by Janus Capital and the subadvisers to the Funds, taking into account the investment objective and strategy of each Fund and the knowledge the Trustees gained from their regular meetings with management on at least a quarterly basis and their ongoing review of information related to the Funds. In addition, the Trustees reviewed the resources and key personnel of Janus Capital and each subadviser, especially those who provide investment management services to the Funds. The Trustees also considered other services provided to the Funds by Janus Capital or the subadvisers, such as managing the execution of portfolio transactions and the selection of broker-dealers for those transactions, serving as the Funds' administrator, monitoring adherence to the Funds' investment restrictions, producing shareholder reports, providing support services for the Trustees and Trustee committees, communicating with shareholders and overseeing the activities of other service providers, including monitoring compliance with various policies and procedures of the Funds and with applicable securities laws and regulations.

102 Janus Growth Funds April 30, 2007

the Funds whose performance lagged that of the median of their peers for certain periods, the quality of those services had been consistent with or superior to quality norms in the industry; and that the Funds were likely to benefit from the continued provision of those services. They also concluded that Janus Capital and each subadviser had sufficient personnel, with the appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract and retain well-qualified personnel.

Performance of the Funds

The Trustees considered the performance results of each Fund over various time periods. They reviewed information comparing each Fund's performance with the performance of comparable funds and peer groups identified by Lipper Inc., an independent provider of investment company data, and with the Fund's benchmark index. They concluded that the performance of most Funds was good to very good under current market conditions. Although the performance of some Funds lagged that of the median of their peers for certain periods, the Trustees also concluded that Janus Capital had taken appropriate steps to address those instances of under-performance and that the more recent performance of most of those Funds had been improving.

Costs of Services Provided

The Trustees examined information on the fees and expenses of each Fund in comparison to similar information for other comparable funds as provided by Lipper. They also reviewed an analysis of that information provided by their independent fee consultant and noted that the rate of management (investment advisory and administrative) fees for most of the Funds, in some cases after contractual expense limitations, was below the mean management fee rate of the respective peer group of funds selected by Lipper.

The Trustees considered the methodology used by Janus Capital and each subadviser in determining compensation payable to portfolio managers, the competitive environment for investment management talent and the competitive market for mutual funds in different distribution channels. They concluded that the compensation methodology provided a good alignment of the interests of the portfolio managers with the interests of Fund shareholders.

The Trustees also reviewed management fees charged by Janus Capital to its separate account clients and to its subadvised funds (for which Janus Capital provides only services related to portfolio management). Although in most instances subadvisory and separate account fee rates for various investment strategies were lower than management fees for Funds having a similar strategy, the Trustees noted that, under the management agreements with the Funds, Janus Capital performs significant additional services for the Funds that it does not provide to those other clients, including administrative services, oversight of the Funds' other service providers, Trustee support, regulatory compliance and numerous other services, and that, in serving the Funds, Janus Capital assumes many legal risks that it does not assume in servicing its other clients. Moreover, they noted that the spread between the average fee rates charged to the Funds and the fee rates that Janus Capital charged to its separate account clients was significantly smaller than the average spread for such fee rates of other advisers, based on publicly available data and research conducted by their independent fee consultant.

In considering the fees charged by Janus Capital, the Trustees noted that, in addition to the previously approved performance fee structure for Janus Worldwide Fund and certain other Funds that would become operative in February 2007, they also had negotiated with Janus Capital a temporary waiver of a portion of the investment advisory fee paid by Janus Worldwide Fund to Janus Capital to provide for a possible reduction in the rate of advisory fee payable by the Fund for the period July 1, 2006 through January 31, 2007 if the investment performance of the Fund should lag that of its benchmark index performance over the applicable performance measurement period.

The Trustees reviewed information on the profitability of Janus Capital and its affiliates of their relationships with each Fund, as well as an explanation of the methodology utilized in allocating various expenses among the Funds and other clients. The Trustees also reviewed the financial statements of Janus Capital's parent company and its corporate structure. In their review, the Trustees considered whether Janus Capital and each subadviser receive adequate incentives to manage the Funds effectively. The Trustees recognized that profitability comparisons among investment advisers are difficult because very little comparative information is publicly available and profitability of any adviser is affected by numerous factors, including the organizational structure of the particular manager, the types of funds and other accounts it manages, possible other lines of business, the methodology for allocating expenses and the adviser's capital structure and cost of capital. However, based on the information available and taking those factors into account, the Trustees concluded that Janus Capital's

Janus Growth Funds April 30, 2007 103

Additional Information (unaudited) (continued)

profitability with respect to each Fund in relation to the services rendered was not unreasonable.

The Trustees concluded that the management fees and other compensation payable by each Fund to Janus Capital and its affiliates, as well as the fees paid by Janus Capital to the subadvisers of subadvised Funds, were reasonable in relation to the nature and quality of the services provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies and the fees Janus Capital and the subadviser charge to other clients. The Trustees also concluded that the overall expense ratio of each Fund was reasonable, taking into account the size of the Fund, the quality of services provided by Janus Capital and any subadviser, the investment performance of the Fund and any expense limitations agreed to by Janus Capital.

Economies of Scale

The Trustees considered information about the potential for Janus Capital to realize economies of scale as the assets of the Funds increase. They noted that, although most Funds pay advisory fees at a fixed rate as a percentage of net assets, without any breakpoints, the management fee rate paid by each Fund, after any contractual expense limitations, was below the mean management fee rate of the Fund's peer group selected by Lipper; and, for those Funds whose expenses are being reduced by the contractual expense limitations of Janus Capital, Janus Capital is subsidizing the Funds because they have not reached adequate scale. Moreover, as the assets of many of the Funds declined in the past few years, these Funds benefited from having advisory fee rates that remained constant rather than increasing as assets declined. In addition, performance fee structures have been implemented for several Funds that will cause the effective rate of advisory fees payable by such a Fund to vary depending on the investment performance of the Fund relative to its benchmark index over the measurement period; and a few Funds have fee schedules with breakpoints and reduced fee rates above certain asset levels. The Trustees also noted that the Funds share directly in economies of scale through lower charges of third-party service providers based on the combined scale of all of the Funds. Based on all of the information they reviewed, the Trustees concluded that the current fee structure of each Fund was reasonable and that the current rates of fees do reflect a sharing between Janus Capital and the Fund of economies of scale at the current asset level of the Fund.

Other Benefits to Janus Capital

The Trustees also considered benefits that accrue to Janus Capital and its affiliates from their relationships with the Funds. They recognized that two affiliates of Janus Capital separately serve the Funds as transfer agent and distributor, respectively, and that the transfer agent receives compensation directly from the non-money market Funds for services provided. The Trustees also considered Janus Capital's past and proposed use of commissions paid by the Funds on their portfolio brokerage transactions to obtain proprietary research products and services benefiting those Funds and/or other clients of Janus Capital, as well as Janus Capital's prior agreement not to use any Fund's brokerage transactions to obtain third party research products or services. The Trustees concluded that Janus Capital's use of "soft" commission dollars of a Fund to obtain proprietary research products and services was consistent with regulatory requirements and guidelines and was likely to benefit the Funds. The Trustees also concluded that, other than the services provided by Janus Capital and its affiliates pursuant to the agreements and the fees to be paid by each Fund therefor the Funds and Janus Capital may potentially benefit from their relationship with each other in other ways. They concluded that Janus Capital benefits from the receipt of proprietary research products and services acquired through commissions paid on portfolio transactions of the Funds and that the Funds benefit from Janus Capital's receipt of those products and services as well as research products and services acquired through commissions paid by other clients of Janus Capital. They further concluded that success of any Fund could attract other business to Janus Capital or other Janus funds and that the success of Janus Capital could enhance Janus Capital's ability to serve the Funds.

After full consideration of the above factors as well as other factors, all of the Trustees, including all of the Independent Trustees, concluded that the proposed continuation of the investment advisory agreement for each Fund, and the subadvisory agreement for each subadvised Fund, was in the best interest of the respective Funds and their shareholders.

1. PERFORMANCE OVERVIEWS

Performance overview graphs compare the performance of a hypothetical $10,000 investment in each Fund with one or more widely used market indices. The hypothetical example does not represent the returns of any particular investment.

When comparing the performance of a Fund with an index, keep in mind that market indices do not include brokerage commissions that would be incurred if you purchased the individual securities in the index. They also do not include taxes payable on dividends and interest or operating expenses incurred if you maintained a Fund invested in the index.

Average annual total returns are also quoted for each Fund. Average annual total return is calculated by taking the growth or decline in value of an investment over a period of time, including reinvestment of any dividends, distributions and capital gains, then calculating the annual compounded percentage rate that would have produced the same result had the rate of growth been constant throughout the period. Average annual total return does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or redemptions of Fund shares.

Pursuant to federal securities rules, expense ratios shown in the performance chart reflect subsidized and unsubsidized ratios for the past fiscal year. The total annual fund operating expenses ratio is gross of any fee waivers, reflecting a Fund's unsubsidized expense ratio. The net annual fund operating expenses ratio (if applicable) includes contractual waivers of Janus Capital and/or Janus Services, LLC and reflects a Fund's subsidized expense ratio. Both the total annual fund operating expenses ratio and net annual fund operating expenses ratio are based on average net assets as of the fiscal year ended October 31, 2006. The ratios also include expenses indirectly incurred by the Fund as a result of investing in other investment companies or pooled investments, which are not reflected in the "Financial Highlights" of this report. As a result, these ratios may be higher or lower than those shown in the "Financial Highlights" in this report. All expenses are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

2. SCHEDULES OF INVESTMENTS

Following the performance overview section is each Fund's Schedule of Investments. This schedule reports the industry concentrations and types of securities held in each Fund on the last day of the reporting period. Securities are usually listed by type (common stock, corporate bonds, U.S. Government obligations, etc.) and by industry classification (banking, communications, insurance, etc.). Holdings are subject to change without notice.

The value of each security is quoted as of the last day of the reporting period. The value of securities denominated in foreign currencies is converted into U.S. dollars.

Funds that invest in foreign securities also provide a summary of investments by country. This summary reports the Fund's exposure to different countries by providing the percentage of securities invested in each country. The country of each security represents the country in which the company is incorporated.

2A. FORWARD CURRENCY CONTRACTS

A table listing forward currency contracts follows each Fund's Schedule of Investments (if applicable). Forward currency contracts are agreements to deliver or receive a preset amount of currency at a future date. Forward currency contracts are used to hedge against foreign currency risk in the Fund's long-term holdings.

The table provides the name of the foreign currency, the settlement date of the contract, the amount of the contract, the value of the currency in U.S. dollars and the amount of unrealized gain or loss. The amount of unrealized gain or loss reflects the change in currency exchange rates from the time the contract was opened to the last day of the reporting period.

2B. FUTURES

A table listing futures contracts follows each Fund's Schedule of Investments (if applicable). Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. Futures are used to hedge against adverse movements in securities prices, currency risk or interest rates.

The table provides the name of the contract, number of contracts held, the expiration date, the principal amount, value and the amount of unrealized gain or loss. The amount of unrealized gain or loss reflects the marked-to-market amount for the last day of the reporting period.

2C. OPTIONS

A table listing option contracts follows each Fund's Schedule of Investments (if applicable). Option contracts are contracts that obligate a Fund to sell or purchase an underlying security at a fixed price, upon exercise of the option. Options are used to hedge against adverse movements in securities prices, currency risk or interest rates.

The table provides the name of the contract, number of contracts held, the expiration date, exercise price, value and premiums received.

Financial Statements (unaudited) (continued)

3. STATEMENT OF ASSETS AND LIABILITIES

This statement is often referred to as the "balance sheet." It lists the assets and liabilities of the Funds on the last day of the reporting period.

The Funds' assets are calculated by adding the value of the securities owned, the receivable for securities sold but not yet settled, the receivable for dividends declared but not yet received on stocks owned and the receivable for Fund shares sold to investors but not yet settled. The Funds' liabilities include payables for securities purchased but not yet settled, Fund shares redeemed but not yet paid and expenses owed but not yet paid. Additionally, there may be other assets and liabilities such as unrealized gain or loss on forward currency contracts.

The section entitled "Net Assets Consist of" breaks down the components of the Funds' net assets. Because Funds must distribute substantially all earnings, you'll notice that a significant portion of net assets is shareholder capital.

The last section of this statement reports the net asset value ("NAV") per share on the last day of the reporting period. The NAV is calculated by dividing the Funds' net assets (assets minus liabilities) by the number of shares outstanding.

4. STATEMENT OF OPERATIONS

This statement details the Funds' income, expenses, gains and losses on securities and currency transactions, and appreciation or depreciation of current Fund holdings.

The first section in this statement, entitled "Investment Income," reports the dividends earned from stocks and interest earned from interest-bearing securities in the Funds.

The next section reports the expenses and expense offsets incurred by the Funds, including the advisory fee paid to the investment adviser, transfer agent fees and expenses, and printing and postage for mailing statements, financial reports and prospectuses. Expense offsets, if any, are also shown.

The last section lists the increase or decrease in the value of securities held in the Funds. Funds realize a gain (or loss) when they sell their position in a particular security. An unrealized gain (or loss) refers to the change in net appreciation or depreciation of the Funds during the reporting period. "Net Realized and Unrealized Gain/(Loss) on Investments" is affected both by changes in the market value of Fund holdings and by gains (or losses) realized during the reporting period.

5. STATEMENT OF CHANGES IN NET ASSETS

This statement reports the increase or decrease in the Funds' net assets during the reporting period. Changes in the Funds' net assets are attributable to investment operations, dividends, distributions and capital share transactions. This is important to investors because it shows exactly what caused the Funds' net asset size to change during the period.

The first section summarizes the information from the Statement of Operations regarding changes in net assets due to the Funds' investment performance. The Funds' net assets may also change as a result of dividend and capital gains distributions to investors. If investors receive their dividends in cash, money is taken out of the Fund to pay the distribution. If investors reinvest their dividends, the Fund's net assets will not be affected. If you compare each Fund's "Net Decrease from Dividends and Distributions" to the "Reinvested dividends and distributions," you'll notice that dividend distributions had little effect on each Fund's net assets. This is because the majority of Janus investors reinvest their distributions.

The reinvestment of dividends is included under "Capital Share Transactions." "Capital Shares" refers to the money investors contribute to the Funds through purchases or withdraw via redemptions. The "Redemption Fees" refers to the fee paid to the applicable Funds for shares held for three months or less by a shareholder. The Funds' net assets will increase and decrease in value as investors purchase and redeem shares from the Funds.

6. FINANCIAL HIGHLIGHTS

This schedule provides a per-share breakdown of the components that affect a Fund's NAV for current and past reporting periods. Not only does this table provide you with total return, it also reports total distributions, asset size, expense ratios and portfolio turnover rate.

The first line in the table reflects the NAV per share at the beginning of the reporting period. The next line reports the net investment income per share, which comprises dividends and interest income earned on securities held by the Fund. Following is the total of gains/(losses), realized and unrealized. Dividends and distributions are then subtracted to arrive at the NAV per share at the end of the period.

The next line reflects the average annual total return reported the last day of the period.

Also included are the expense ratios, or the percentage of net assets that were used to cover operating expenses during the period. Expense ratios vary across the Funds for a number of reasons, including the differences in management fees, the average shareholder account size and the extent of foreign investments, which entail greater transaction costs.

106 Janus Growth Funds April 30, 2007

The Funds' expenses may be reduced through expense reduction arrangements. These arrangements may include the use of balance credits or transfer agent fee offsets. The Statement of Operations reflects total expenses before any such offset, the amount of the offset and the net expenses. The expense ratios listed in the Financial Highlights reflect total expenses prior to any expense offsets (gross expense ratio) and after the expense offsets (net expense ratio). Both expense ratios reflect expenses after waivers (reimbursements), if applicable.

The ratio of net investment income/(loss) summarizes the income earned less expenses, divided by the average net assets of a Fund during the reporting period. Don't confuse this ratio with a Fund's yield. The net investment income ratio is not a true measure of a Fund's yield because it doesn't take into account the dividends distributed to the Fund's investors.

The next figure is the portfolio turnover rate, which measures the buying and selling activity in a Fund. Portfolio turnover is affected by market conditions, changes in the asset size of a Fund, the nature of the Fund's investments and the investment style of the portfolio manager. A 100% rate implies that an amount equal to the value of the entire portfolio is turned over in a year; a 50% rate means that an amount equal to the value of half the portfolio is traded in a year; and a 200% rate means that an amount equal to the value of the portfolio is traded every six months.

Notes

Janus Growth Funds April 30, 2007 109

Janus provides access to a wide range of investment disciplines.

Asset Allocation

Janus asset allocation funds invest in several underlying mutual funds, rather than individual securities, in an attempt to offer investors an instantly diversified portfolio. Janus Smart Portfolios are unique in their combination of funds that leverage the fundamental research approach of Janus with funds supported by the risk-managed, mathematical investment process of INTECH (a Janus subsidiary).

Growth

Janus growth funds focus on companies believed to be the leaders in their respective industries, with solid management teams, expanding market share, margins and efficiencies.

Core

Janus core funds seek investments in more stable and predictable companies. These funds look for a strategic combination of steady growth and for certain funds, some degree of income.

Risk-Managed

Our risk-managed fund seeks to outperform its index while maintaining a risk profile equal to or lower than the index itself. Managed by INTECH (a Janus subsidiary), this fund uses a mathematical process in an attempt to build a more "efficient" portfolio than the index.

Value

Janus value funds invest in companies they believe are poised for a turnaround or are trading at a significant discount to fair value. The goal is to gain unique insight into a company's true value and identify and evaluate potential catalysts that may unlock shareholder value.

International & Global

Janus international and global funds seek to leverage Janus' research capabilities by taking advantage of inefficiencies in foreign markets, where accurate information and analytical insight are often at a premium.

Bond & Money Market

Janus bond funds attempt to provide less risk relative to equities while seeking to deliver a competitive total return through high current income and appreciation. Janus money market funds seek maximum current income consistent with stability of capital.

For more information about our funds, go to www.janus.com.

An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Useful Information About Your Fund Report

Management Commentaries

Fund Expenses

We believe it's important for our shareholders to have a clear understanding of Fund expenses and the impact they have on investment return.

Example

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including redemption fees (where applicable) (and any related exchange fees) and (2) ongoing costs, including management fees, administrative services fees (where applicable), and other Fund expenses. The example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the six-month period from November 1, 2006 to April 30, 2007.

Actual Expenses

The first line of the table in each example provides information about actual account values and actual expenses. You may use the information in this line, 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 first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during the period.

Hypothetical Example for Comparison Purposes

By written agreement, Janus Capital Management LLC ("Janus Capital") has agreed to waive the transfer agency fees payable to certain limits for the Institutional Shares of Janus Mid Cap Value Fund and Janus Small Cap Value Fund until at least March 1, 2008. Expenses in the examples reflect application of these waivers. Had the waivers not been in effect, your expenses would have been higher. More information regarding the waivers is available in the Funds' prospectuses.

Performance Overview

Janus Balanced Fund advanced 7.24% for the six-month period ending April 30, 2007, compared with a 5.85% return by the Balanced Index, an internally calculated secondary benchmark. The Balanced Index is composed of a 55% weighting in the S&P 500^® Index, the Fund's primary benchmark, and a 45% weighting in the Lehman Brothers Government/Credit Index, the Fund's other secondary benchmark, which returned 8.60% and 2.47%, respectively.

Economic Update

Fund Snapshot

The fund combines the growth potential of stocks with the balance of bonds.

With most U.S. equity indexes near all-time highs at the end of the period, we closely monitored several fundamental factors for directional cues. First, despite the weakness in the U.S. housing sector and the associated credit quality issues in the subprime mortgage market, the U.S. unemployment rate was near historical lows at period end, mitigating the impact of the housing slowdown on consumer spending and the overall U.S. economy. Second, U.S. corporate profit growth experienced double-digit gains for several years, which, combined with strong liquidity from corporate M&A and private equity transactions, supported higher equity valuations.

Stock Selection Benefited Performance

Fund performance for the period reflected solid stock selection, particularly in the financials, consumer discretionary and consumer staples sectors. The Fund's exposure to the both cyclical and non-cyclical consumer related companies proved particularly favorable.

Exposure to consumer staples company Reckitt Benckiser, a company that manufactures and distributes household cleaning products, boosted performance as the company benefited from strong earnings including top-line growth, margin expansion and solid cash flows.

Another standout was our investment in Canadian company Potash Corporation of Saskatchewan. The company currently holds much of the world's excess supply of potash, an important ingredient in fertilizer. In the fourth quarter of 2006, Potash's leading market position in potash reserves was enhanced following the flood of a competitor's mine.

The Fund also benefited from select positions in the healthcare sector. Notably, Swiss drug maker Roche Holding continued to capitalize on healthy demand for its cancer drugs. We remain constructive on the long-term sales growth potential tied to the expanded European roll-out of key cancer drug, Avastin.

Select Healthcare and Industrial Stocks Detracted from Results

On a negative note, Fund performance was hindered by weakness in its industrial holdings. While negative performance was limited to only four stocks, the Fund's sector position failed to keep pace with the benchmark allocation. Relative results were also dampened by the Fund's lack of exposure to the strong-performing utilities and telecommunications services sectors.

Among individual equity holdings, healthcare company Amgen was pressured by concerns over reimbursements for anemia drug Epogen, as well as from the possibility that the Food and Drug Administration (FDA) might require more stringent warning labeling for Epogen and Amgen's other anemia treatment, Aranesp.

While the Fund's technology stocks generally outperformed during the period, our investment in Samsung Electronics proved a negative. The South Korean semiconductor manufacturer faced worries over demand and pricing trends in its flash memory business.

Janus Core, Risk-Managed and Value Funds April 30, 2007 5

Janus Balanced Fund (unaudited)

Fixed-Income Investments Provided Mixed Results

In an environment where riskier spread-oriented investments outperformed, a conservative posture within the fixed-income holdings hurt Fund performance. In particular, the Fund's exposure to Treasury securities proved detrimental as investors generally favored lower-quality, higher-yield corporate debt as well as mortgage backed securities.

Nonetheless, specific corporate credit holdings, including El Paso, HCA and Owens-Illinois, supported performance. Additionally, the Fund benefited from an out-of-benchmark allocation to short-term bank loans.

Outlook

We intend to watch the labor market closely for any sign of a slowdown, which could impact consumer sentiment and economic growth. Similarly, we plan to monitor the higher-quality prime mortgage market and other areas of consumer lending for any indication of credit quality deterioration. We will continue to watch both the future path of corporate earnings and the overall liquidity in the markets in an effort to determine whether current valuations can be sustained.

Going forward, we remain constructive on the outlook for the financial markets, but caution that uncertainty over the strength of the economy and the Fed response could contribute to short-term volatility. In this environment, we will continue to take a balanced approach to investing, using our rigorous fundamental research-driven approach to seek to uncover the best opportunities in both the equity and fixed-income markets.

and characteristic information

Funds that invest in bonds have the same interest rate, inflation, and credit risks that are associated with the underlying bonds owned by the Fund. Unlike owning individual bonds, there are ongoing fees and expenses associated with owning shares of bond funds. The return of principal is not guaranteed due to net asset value fluctuation that is caused by changes in the price of specific bonds held in the Fund and selling of bonds within the Fund by the portfolio manager.

There is no assurance that the investment process will consistently lead to successful investing.

See Notes to Schedules of Investments for index definitions.

Janus Contrarian Fund (unaudited)

Ticker: JSVAX

David Decker
portfolio manager

Dear Shareholders,

Thank you for your continued investment in Janus Contrarian Fund. The Fund returned 22.86% during the six-month period ended April 30, 2007, outperforming the 8.60% gain of the S&P^®500 Index, the Fund's primary benchmark and the 12.50% return of the Morgan Stanley Capital International All Country World Index^SM , the Fund's secondary benchmark.

Fund Snapshot

This fund relies on detailed research to find out-of-favor companies believed to have unrecognized value.

Investment Philosophy and Process

The strategy of the Janus Contrarian Fund is to invest in high quality companies when we believe the intrinsic value is not properly reflected in the public markets. I believe that by taking a contrarian position and investing in companies that are out-of-favor or misunderstood, the relationship between risk and reward will often be in our favor due to the fact that much of the "negative news" has already been factored into the valuation of the company. In this way, when our analysis is wrong, the downside should not be severe because the valuation of the company did not have high embedded expectations. Conversely, when our analysis is correct, there should be an excellent opportunity to generate strong returns. The goal of the Fund is to build a portfolio of companies that offer this asymmetrically positive relationship between risk and reward, which in the long run should generate strong risk adjusted returns.

I think it is very important to remember that the intrinsic value of a company is a function of the future stream of cash flows over many years, not the earnings that a company may or may not generate in the next quarter or two. The analyst team and I are constantly looking for situations where we believe the market appears overly focused on short-term earnings as opposed to real intrinsic value (the real value of the company rather than its market price) thereby leaving the company undervalued.

As an example, in the October 31, 2006 letter to shareholders, I wrote about the recent purchase of Owens-Illinois (OI), which was added to the portfolio during a very difficult operating environment. With high energy and transportation costs affecting the near term performance of the company, as well as concerns about the health of its CEO, OI's market value had declined to a level that we believed offered a very compelling investment opportunity. Our analysis suggested that the downside was fully factored into the market price, giving us a very favorable risk-reward. Since the purchase last year, OI has appreciated significantly as its operating cost issues proved temporary and its new CEO, Al Stroucken, continued to build upon the operational improvements set in motion by previous CEO, Steve McCracken.

Impact of Private Equity

Over the past year we have witnessed an increasing number of private equity buyers taking companies private, and the Fund has been the beneficiary of some of these "take-out" transactions. As I will explain, however, for Janus Contrarian Fund investors the impact of this dynamic has been both good and bad. While the Fund has been the recipient of quick gains from some of these transactions, I am not in favor of high-quality companies being taken out of the public markets at valuations that I think do not fully reflect the true intrinsic value of the targeted company. In my view, we have seen this occur most often in management buyouts (MBOs), when the value transfer is substantially in favor of the buyer due to the fact that it is unlikely that management would overpay for the one asset it knows best: its own company. For this reason, while Janus Contrarian Fund has been the beneficiary of gains from companies we owned that were recently taken private, it is not always something to celebrate.

An example of this was the recent take-out of Station Casinos, a company that has been a significant position in the Contrarian Fund for a number of years. While its recent take-out price appears fairly valued based on near-term earnings, I believe the long-term opportunity to create value is substantial. It is therefore unfortunate to see the company taken private irrespective of the premium we received for our shares.

We have also seen take-outs where we believe the buyer adequately compensated us for the value of our shares, and in those situations I am more comfortable with the take-out. As a recent example, SLM Corporation (Sallie Mae) was taken out at a 50% premium to its market price. I had built a substantial position in Sallie Mae prior to the take-out because our analysis suggested that, even with the political risks of student lending legislation, the valuation of the company relative to its long-term earnings power was very attractive. However, because risks remained, despite the fact that the take-out price of the company was slightly below what we believed the company was worth, we believe the buyers adequately compensated us given the risk they accepted.

(unaudited)

The companies owned by the Janus Contrarian Fund are ones that I believe are capable of compounding long-term value and I will only sell them when we believe the market value is higher than what we believe to be its intrinsic value. Sometimes the unfortunate consequence of private equity transactions is that we must give up our shares at a value that doesn't always fully reflect our calculation of intrinsic value, even when we are not in favor of the deal. We will nonetheless always do our best to ensure that shareholders of Janus Contrarian Fund receive the best price in a transaction.

Performance

Despite the generally strong performance of the positions in the portfolio, there was weakness in our two Japanese financial companies, Mitsubishi UFJ Financial Group and Mizuho Financial Group, down about 16% and 21% respectively. I am extremely comfortable with both of these positions and I took the opportunity to increase the position size of both. The Indian market has also been weak recently due to rising interest rates as a result of increasing inflation. While I would not be surprised to see the Indian market continue to struggle during this period, I continue to feel very confident in the outlook for the positions that are owned in the Fund.

Conclusion

While my views of the market do not affect the process of investing for Janus Contrarian Fund, I have become increasingly concerned that the market is not discounting the potential negative impact of the collapse of the U.S. housing market as well as the subprime lending market, and would therefore expect a much more volatile and potentially lower return market in the future. The strategy of Janus Contrarian Fund has always been to buy companies anywhere in the world that we believe are undervalued. This is not to say that in weak markets the positions in the Fund will not go down (this was the case in March); however, we attempt to mitigate downside risk by owning companies that do not have high embedded expectations. Despite my continued concerns about potential economic risks, I am confident that the Fund owns high-quality and attractively valued companies that can create long-term economic value.

Thank you for your continued investment in the Janus Contrarian Fund.

Janus Fundamental Equity Fund (unaudited)

Ticker: JAEIX

Minyoung Sohn
portfolio manager

The previous six-month period was a good one for stocks, with the market overcoming a sharp correction at the end of February. On February 27th, the S&P 500^® Index lost nearly 50 points from 1449 to 1399, a 3.47% drop, following the 9% plunge in the local Chinese stock markets and ensuing weakness in the European markets in overnight trading.¹ We now know that this sell-off was largely technical in nature, but at the time, this sparked fears of another market correction similar to the one triggered on May 10, 2006. Despite the correction, we now see that the Chinese markets have continued to surge ahead, with the U.S. stocks exhibiting similar muster. This raises the question, "Did the February correction even matter?"

Fund Snapshot

This conservative growth fund from Janus relies on detailed research to drive its fundamental approach to investing in core holdings and opportunistic companies.

In light of this view, the Fund played defense against a U.S. economic slowdown. Globalization was a recurring theme in the portfolio – whether it was General Electric, Procter & Gamble or Boeing – because I believe that the Fund will benefit from long-term exposure to faster economic growth overseas. From a sector perspective, the Fund was heavily overweight in energy, so I believe that performance should hold up relatively well in any "oil price shock" scenario. Finally, I intend to carefully monitor U.S. consumer exposure, although at the end of the period, the Fund still held positions in stocks such as Tiffany, Nordstrom and Best Buy due to the analysts' conviction in each company's specific investment merits. If I am wrong, and if the market decides that the positives outweigh the concerns, the Fund may underperform in 2007.

For the six-month period ending April 30, 2007, the Fund returned 8.72%, exceeding the 8.60% return of the S&P 500^® Index, the primary benchmark, and the 8.42% return of the Russell 1000^® Growth Index, the secondary benchmark.

Stocks That Helped Performance

Hess (formerly Amerada Hess) and Valero Energy were the two largest contributors to performance in the period.

The Fund's holding in Hess gained nearly 40% in the period and was the largest contributor to performance. The Fund owns Hess because I believe that the company is undervalued relative to the rapid improvements in the upstream oil and gas exploration and development business. An industry laggard just a few years ago, Hess delivered solid upstream performance. I believe that the value of recent discoveries in the Gulf of Mexico is not reflected in the share price at the end of the period. As these projects get sanctioned, I expect the company will be able to focus on strong organic reserve replacement, competitive finding and development costs and attractive organic production growth. I held the Fund's large position in Hess because I believe that the shares will re-rate higher as the company completes this execution.

Valero Energy was another large contributor in the period. Valero was built under the visionary leadership of Bill Greehey, who acquired fundamentally advantaged refining assets at trough valuations. The refining business strengthened considerably over the past few years as gasoline demand has outpaced the industry's ability to produce gasoline. Recently, Valero named Bill Klesse to lead the company. In recent meetings with the company, I was impressed by Mr. Klesse and his focus on cost and capital spending discipline, capital management and shareholder value creation. In 2006, Valero reduced its share count by more than 5%, and the company appears on pace to reduce its shares outstanding by over 10% in 2007. Under Mr. Klesse, Valero is reviewing its asset portfolio in an effort to further enhance value by selling refiners which may be worth more to others than they are to Valero. Valero recently announced the sale of its Lima refinery for $1.9 billion. The proceeds from Lima, as well as other potential asset sales, should further add to its share repurchase activity. I applaud management's focus on value creation as I believe that these actions will continue to drive shareholder value. I held the Fund's position.

The Fund's holding in EMC was another large contributor in the period. EMC is a leader in storage hardware and software solutions. I bought EMC through the course of 2006 at an average cost of less than $11 per share because I believed that the shares were attractively valued on a sum-of-the-parts basis. The key to this thesis is my extremely positive view of VMware, a wholly-owned subsidiary of EMC. VMware is the leader in virtualization software, which allows users to run virtual machines on a single piece of hardware. This functionality enables users to more fully utilize the computing capacity of their servers, resulting in significant procurement and operational savings. Despite the buzz and excitement

22 Janus Core, Risk-Managed and Value Funds April 30, 2007

(unaudited)

around virtualization, Janus research suggests VMware is still in its very early stages of rapid growth as this emerging technology enters mainstream adoption. We estimate that VMware sales will be approximately $1 billion in 2007, which could be valued as richly as 10 times sales, placing a value of $10 billion on VMware. This would then represent $5 per share of value for each share of EMC. When the Fund was completing its purchase in EMC at less than $11 per average share price, adjusting for cash and estimated value of VMware, I believed that I was buying the rest of EMC for well under 1.0 times sales. While investing in companies on a sum-of-the-parts-based analysis can admittedly demand patience, I believe that the investment in EMC may be rewarded due to the pending Initial Public Offering of VMware as a catalyst.

Stocks That Hurt Performance

The Fund's position in Advanced Micro Devices (AMD) was the largest detractor, with the shares losing 35.03% in the period. AMD has been a frequent topic of my quarterly commentary since 2005 – both on the upside and downside. To review, the Fund owns a large position in AMD because I believe that the competitive structure of the microprocessor industry is changing into a true duopoly. The corollary to the investment thesis is that AMD should be able to convert its market share into profitable earnings growth. If I am right on these two points, then it seems logical that if AMD can capture, for example, 30% of the sales and profits of the microprocessor industry, that over time investors should reward AMD with an equivalent 30% of the combined value of Intel, its competitor, and AMD. As of period-end, I estimate that while AMD captures a 20% share of industry revenue, it carries only 7% of the industry enterprise value.

In addition to AMD, the Fund's holding in Whole Foods Market was the second-largest detractor to performance. I bought Whole Foods in 2006 based on a positive view of the long-term secular growth of organic and natural foods. Prior to buying the position, the company had been reporting very robust same-store sales growth (or "comps") and much of this momentum began to be reflected in very strong stock performance. However, the shares have declined in recent quarters after the company reported slowing comps, which disappointed the market because it had grown accustomed to comps in excess of 10%. In my view, the Whole Foods story is one typical of growth stocks. In my view, there are different points in time when stocks struggle as they grow into their valuation. In other words, it may take a year or two for the company to increase its earnings to catch up to the expectations embedded in its share price. Sometimes, as in the case of Whole Foods, the share price will deflate with lower expectations but then can grow again with earnings growth. I believe what is most important, however, is that Whole Foods has a strong brand, a national footprint in the category and holds of the promise of secular growth for years to come. I held the position.

Closing Comments

At period end, the stock market seemed to be well-supported by a three-legged stool of better-than-expected corporate earnings, substantial corporate and private equity liquidity and expectations of interest rate cuts later this year. These are indeed reasons to be bullish, but I am concerned that inflationary pressures may not allow the Federal Reserve (Fed) to cut rates in the classic mid-cycle slowdown scenario. In my view, the market has also not weighed the possibility of geopolitical risk and the resulting volatility of an "oil price shock." Housing and its potential negative spillover is a wildcard and I believe is too tough to call.

You will notice that your Fund's name was changed from "Janus Core Equity Fund" to "Janus Fundamental Equity Fund." This was designed to better articulate the investment strategy of the Fund. The Fund is built on our research-intensive bottoms-up stock-picking process. Over 80% of the Fund was invested in stocks internally-rated by the Janus investment team as "buy" or "strong buy."

As always, I promise you my utmost effort in the periods ahead. In addition, the overwhelming portion of my personal mutual fund investments are here at Janus in the two Funds under my charge, Janus Fundamental Equity Fund and Janus Growth and Income Fund, and I continue to contribute every month to both.

Thank you for your investment in Janus Fundamental Equity Fund.

Janus Growth and Income Fund (unaudited)

Ticker: JAGIX

Minyoung Sohn
portfolio manager

The previous six-month period was a good one for stocks, with the market overcoming a sharp correction at the end of February. On February 27th, the S&P 500^® Index lost nearly 50 points from 1449 to 1399, a 3.47% drop, following the 9% plunge in the local Chinese stock markets and ensuing weakness in the European markets in overnight trading.¹ We now know that this sell-off was largely technical in nature, but at the time, this sparked fears of another market correction similar to the one triggered on May 10, 2006. Despite the correction, we now see that the Chinese markets continued to surge ahead with the U.S. stocks exhibiting similar muster. This raises the question, "Did the February correction even matter?"

Fund Snapshot

This conservative growth fund from Janus combines core holdings and opportunistic companies with income-oriented securities, seeking to deliver consistent returns through all types of market conditions.

In light of this view, the Fund played defense against a U.S. economic slowdown. Globalization was a recurring theme in the portfolio – whether it was General Electric, Procter & Gamble, UBS or Infosys Technologies – because I believe that the Fund will benefit from long term exposure to faster economic growth overseas. From a sector perspective, the Fund was heavily overweight in energy, so I believe that performance should hold up relatively well in any "oil price shock" scenario. Finally, I intend to carefully monitor U.S. consumer exposure, although at period end the Fund held positions in Tiffany, Nordstrom and Best Buy due to the analysts' conviction in each company's specific investment merits. If I am wrong, and if the market decides that the positives outweigh the concerns, the Fund may underperform in 2007.

For the six-month period ending April 30, 2007, the Fund performed approximately in line with both the S&P 500^® Index, the primary benchmark, and the Russell 1000^® Growth Index, the secondary benchmark. During the period, the Fund returned 8.61%, exceeding the 8.60% return of the S&P 500^® Index and the 8.42% return of the Russell 1000^® Growth Index.

First, a Few Words on Process and Portfolio Construction

Before discussing the factors impacting performance over this six-month period, I would like to share my thoughts on the Fund's poor relative performance in calendar year 2006. I took some steps at the beginning of this year in an effort to improve performance and reduce portfolio volatility. Looking back, 2006 was a disappointing year for the Fund, but part of the severe underperformance was due to what I would characterize as faulty portfolio construction during a time when the Fund's performance proved to be "topsy-turvy" due to periods of market volatility. Whereas stock-picking drove the strong relative performance in 2004 and 2005, it was the reason for underperformance last year, as the portfolio was too highly exposed to active risk from just a handful of stocks. Although I expect to have a percentage of the holdings return less than the benchmark in any measurement period, in 2006 the impact of the "losers" was too large relative to the majority of the stocks that delivered positive returns. In an attempt to reduce portfolio volatility, I increased the number of stocks in the portfolio by selling approximately 15% of the Fund, pro rata across nearly all holdings. This reduced the concentration of portfolio assets in the top 10 and 20 positions from approximately 35% and 55% to 30% and 50%, respectively during the period. In an effort to improve performance, I used these proceeds to establish new positions in stocks internally- rated as "buy" or "strong buy." I also used a portion of the proceeds to increase the allocation of income-oriented derivative strategies from 6% to nearly 10%.

In the first quarter, we witnessed a real-time test of these portfolio adjustments. Whereas the Fund significantly underperformed the benchmark after the May 10, 2006 correction and the level of underperformance widened throughout the rest of last year, after the most recent correction during March and April 2007, the Fund outperformed its primary benchmark. This was an encouraging sign and it reinforced the importance of portfolio construction.

Stocks That Contributed to Performance

Bharti Airtel, which operates its mobile phone service under the brand "Airtel," is the largest player in India with approximately 21% market share. Bharti shares gained about 67% in the period, and the position was the largest positive

30 Janus Core, Risk-Managed and Value Funds April 30, 2007

(unaudited)

contributor to performance. I bought the position in Bharti in March 2006 because I was bullish on the Indian wireless opportunity. I noted that in India, only 10% of the population had cell phone service, compared to 70% to 100% in markets such as the U.S. and Europe. India's wireless penetration is low even by emerging market standards, compared to countries such as Brazil (52%), China (34%) or Russia (100%).² In March, I believed that the Indian market could be 300 million by 2010 and that Bharti would grow at an even faster rate by taking market share from its competitors. As I tracked the Indian wireless industry over the past year, I was impressed that the market consistently grew faster than our expectation. I previously thought that 25% of the Indian population would have wireless service by 2010, but I now believe that this could exceed 30%. Accordingly, I increased the five-year target for Indian wireless subscribers by 100 million to approximately 400 million. While I feel Bharti stock is expensive on an earnings-multiple basis, I believe that the rich valuation is justified by its growth prospects. I held the position in Bharti, which I believe was one of the best growth stories in the portfolio.

Stocks That Hurt Performance

Advanced Micro Devices, or AMD, has been a frequent topic of my quarterly commentary since 2005 – both on the upside and downside. To review, the Fund owns a large position in AMD because I believe that the competitive structure of the microprocessor industry is changing into a true duopoly. The corollary to the investment thesis is that AMD should be able to convert its market share into profitable earnings growth. If I am right on these two points, then it seems logical that if AMD can capture, for example, 30% of the sales and profits of the microprocessor industry, that over time investors should reward AMD with an equivalent 30% of the combined value of Intel, its competitor, and AMD. As of period-end, I estimate that while AMD captures a 20% share of industry revenue, it carries only 7% of the industry enterprise value.

AMD shares peaked in early 2006 above $40 per share but ended the period below $14 per share. I underestimated Intel's ability to defend its market position through its balance sheet and manufacturing capacity. Intel was far better prepared to weather the margin pressure from the ensuing price war and has forced AMD to pare back its ambitious plan to gain market share. Looking ahead, I am optimistic that the microprocessor market will return to normal (rational) pricing levels later this year as both company's financial results have suffered in the fight to establish market share equilibrium.

Closing Comments

At period end, the stock market seemed to be well-supported by a three-legged stool of better-than-expected corporate earnings, substantial corporate and private equity liquidity and expectations of interest rate cuts later this year. These are indeed reasons to be bullish, but I am concerned that inflationary pressures may not allow the Federal Reserve (Fed) to cut rates in the classic mid-cycle slowdown scenario. In my view, the market has not weighed the possibility of geopolitical risk and the resulting volatility of an "oil price shock." Housing and its potential negative spillover is a wildcard and, I believe is too tough to call.

In my opinion, the real challenge in this market environment of rising interest rates is providing you with attractive risk-adjusted returns (after expenses) and earning our keep in your

investment portfolio. I welcome this challenge, as I am supported by a talented analyst pool. To achieve this, I am holding firm to my strategy of picking stocks one at a time and staying close to the best ideas generated by the Janus research team. As previously discussed, over 80% of the Fund at period end is invested in stocks internally-rated by the Janus investment team as "buy" or "strong buy."

As always, I promise you my utmost effort in the periods ahead. In addition, the overwhelming portion of my personal mutual fund investments are here at Janus in the two Funds under my charge, Janus Growth and Income Fund and Janus Fundamental Equity Fund, and I continue to contribute every month to both.

Thank you for your investment in Janus Growth and Income Fund.

INTECH Risk-Managed Stock Fund (unaudited)

Ticker: JRMSX

Managed by INTECH

Performance Overview

For the six months ended April 30, 2007, INTECH Risk-Managed Stock Fund returned 8.11%. This compares to an 8.60% gain by the S&P 500^® Index, the Fund's benchmark.

Fund Snapshot

This core fund embraces the market's natural volatility in an attempt to deliver index-beating returns with index-like risk.

Investment Strategy in This Environment

While fundamental analysis does not factor into our management of the Fund, fundamentals certainly have a significant impact on the general direction of the market in which we participate. The Fund's goal is to produce returns in excess of its benchmark with an equal or lesser amount of risk.

The Fund's mathematical investing process seeks to build a more efficient Fund than its benchmark, the S&P 500^® Index. With a focus on risk management, investment decisions are governed by a mathematical investment process, which aims to deliver returns over and above the Index over the long-term without assuming additional risk relative to the benchmark. This process does not attempt to predict the direction of the market, nor does it have a particular view of any company in the Fund.

Performance Review

Throughout the period, as stock prices naturally moved, we adjusted each comparable stock's weighting in the Fund in an attempt to keep the Fund more efficient than the Index, without increasing relative risk. While individual stock volatility was low during the period, we believe there was indeed adequate fluctuation overall to allow our process to work well. We continued to implement the mathematical process in a disciplined manner during the period. While other factors may influence performance over the short-term, we believe that the consistent application of our process will help the Fund perform well over the long-term.

However, periods of underperformance such as the one we just experienced are inevitable and should be expected from time to time. From our perspective, the key is to keep these periods of underperformance both short in duration and mild in scope. The extent to which we are successful on that score will ultimately govern the longer-term success of the Fund.

Investment Strategy and Outlook

INTECH's mathematical, risk-managed investment process seeks to outperform the S&P 500^® Index over the long-term, while attempting to control risk. We will continue to implement the process in a disciplined and deliberate manner. As a result, the Fund may experience underperformance during shorter time periods, but has a goal of outperformance over a three- to five-year term. While managing risk will remain essential to our investment process, we will continue to make marginal improvements to the mathematical process, seeking an efficient portfolio that offers better long-term results than its benchmark regardless of the market's direction.

Thank you for your investment in INTECH Risk-Managed Stock Fund.

and characteristic information

The Fund has a performance-based management fee that adjusts upward or downward based on the Fund's performance relative to an approved benchmark index over a performance measurement period.

The voluntary waiver of the Fund's management fee terminated June 25, 2004. Without such waivers, total returns from inception to June 25, 2004 would have been lower.

The proprietary mathematical process used by Enhanced Investment Technologies, LLC ("INTECH") may not achieve the desired results. Since the portfolio is regularly re-balanced, this may result in a higher portfolio turnover rate, higher expenses and potentially higher net taxable gains or losses compared to a "buy and hold" or index fund strategy.

There is no assurance the stated objective(s) will be met.

See Notes to Schedules of Investments for index definitions.

The weighting of securities within the portfolio may differ significantly from the weightings within the index. The index is not available for direct investment; therefore its performance does not reflect the expenses associated with the active management of an actual portfolio.

See "Explanations of Charts, Tables and Financial Statements."

Janus Mid Cap Value Fund (unaudited)

Ticker: JMCVX

Managed by
Perkins, Wolf, McDonnell
and Company, LLC

Performance Overview

The rally that began in the second half of 2006 slowed during the first quarter of 2007. Domestic stocks suffered a mid-quarter decline tied to softness in emerging markets and problems in the subprime lending market. However the market then rebounded quickly and moved to a multiyear high in April as the Federal Reserve dropped its reference to the possibility that a rate increase may be necessary.

Fund Snapshot

This fund seeks to uncover fundamentally strong mid-sized companies with a catalyst for growth not yet recognized by the market.

During the six months ended April 30, 2007, Janus Mid Cap Value Fund's Investor Shares appreciated 11.08% and the Fund's Institutional Shares rose 11.12%, while its benchmark, the Russell Midcap^® Value Index, climbed 12.78%. The Russell Midcap^® Index was up 12.24% and the S&P 500^® Index rose 8.60% in the same period.

Strategy in This Environment

The slight underperformance of the Fund was mainly due to our underweight position in utilities and some weakness in select industrial holdings. However, our overweight position in the materials sector, as well as some strong individual performers, aided returns, as did our underweight position in the consumer discretionary area and financials.

Our sector weightings were relatively unchanged from last period, as is normally the case. We remained overweight in energy, healthcare, industrials and information technology (IT). We were underweight in financials, consumer discretionary and utilities. In general, these relative exposures are a reflection of the number of individual investment opportunities we find rather than any top-down macroeconomic view.

Our biggest underweight for the period was utilities, as our investment philosophy emphasizes companies that we believe have strong balance sheets, positive free cash flow and relatively unregulated franchises. These attributes are rarely found in utilities companies. In the past few years we have been penalized for having an underweight exposure to this group, but over the long term this has been a sound strategy.

In addition, we were underweight financials, largely due to an underweight position in real estate investment trusts (REITs). REITs have enjoyed a tremendous run over the past few years, but we feel the industry is broadly overvalued given that the dividend yield of the typical REIT was less than that of a 10-year Treasury note at period-end and the stocks are selling above most estimates of asset value. In the six-month period ending in April, financials had the least price appreciation of any of the major sectors.

IT and Industrials Weighed on Returns

Looking at individual securities, Avocent, which makes analog and digital KVM (keyboard, video and mouse) switching systems to manage multiple servers, was our weakest performer during the most recent six-month period. The company reported disappointing earnings that we believe are a short-term glitch. We believe that Avocent's long-term fundamentals are positive so we used the price weakness to add to our position.

Southwest Airlines was another performance dampener, as it declined 10% from our recent purchase price. Earnings have been somewhat disappointing as operating costs have increased while passenger load factors have fallen slightly. However, we believe this shortfall is discounted in the stock's historically low valuation, especially given the company's superior balance sheet and leading industry position.

Select Financials and Materials Stocks Aided Performance

AllianceBernstein Holding, one of the largest investment managers in the United States and our Portfolio's largest position, was our top contributor over the last six months. The company's organic growth continued to track at a high single-digit annual rate, with contributions from the company's three distribution channels, including a particularly strong showing in its private client unit. At period end, the stock was supported by its dividend yield.

Our holding in Temple-Inland, a manufacturer of paper, corrugated packaging and building products, was our top individual contributor in the best-performing materials sector. Management responded to pressure from Carl Icahn, one of the company's largest investors, by proposing to split the company into three separate entities.

As has been the case every year except 2002, takeover activity significantly contributed to our results. In the last quarter of 2006, some of the mergers and acquisitions announced included Abbott Laboratories' purchase of Kos Pharmaceuticals,

48 Janus Core, Risk-Managed and Value Funds April 30, 2007

Biomet's takeout by a group of private equity firms and the Bank of New York and Mellon Financial's merger. In 2007, the technology companies Hyperion Solutions and First Data were the primary buyouts. We purchased some of the companies involved in recent deals in 2006 after their prices had declined because of near-term earnings disappointments. This exemplifies our contrarian philosophy of buying franchises we believe have strong, long-term potential at a time when it appears investor expectations are low and more focused on short-term reports rather than on a firm's intrinsic value.

Looking Ahead

We believe that we are well positioned for longer-term trends in the markets. For several quarters we have added to larger-cap stocks as they have become relatively more attractive than small caps and the lower end of the midcap capitalization spectrum. The relative valuations of larger caps are near the lows of recent decades. Thus, given our sensitivity to risk and valuation, the larger caps have become a larger part of our Portfolio. While we recognize that these stocks could lag in the short-term, we believe these equities offer the best long-term risk/reward relationships in the current scenario.

Our style has always accommodated out-of-favor stocks with growth potential that are trading at historically low valuations. Almost every year we have benefited from merger and acquisition activity, which we expect to remain at a high level for the foreseeable future. These factors have been integral to the Fund's consistently strong past performance, even in markets favoring growth, and we believe should continue to serve us well.

As always, we appreciate your joining us as co-investors in the Fund.

Fund Snapshot

This fund searches for small, out-of-favor companies misunderstood by the broader investment community.

Performance Overview

The rally that began in the second half of 2006 slowed during the first quarter of 2007. Domestic stocks suffered a mid-quarter declining tied to softness in emerging markets and problems in the subprime lending market. However, the market then rebounded quickly and moved to a multiyear high in April as the Federal Reserve dropped its reference to the possibility that a rate increase may be necessary.

In the midst of this elevated volatility, during the six months ended April 30, 2007, Janus Small Cap Value Fund's Investor Shares gained 8.03% and the Fund's Institutional Shares rose 8.18%, outpacing their benchmark the Russell 2000^® Value Index, which returned 6.36%.

Both stock selection and group weightings contributed positively to relative performance during the period. The Fund's underweight position to the financial sector paid off in a relative sense, as it was the only sector in the benchmark to post negative returns, whereas, our overweight position to the industrial sector was a benefit given that area's strength. In both cases, our holdings outperformed as well. On the other hand, select holdings within consumer staples and materials lagged and were the Fund's biggest detractors in a relative sense. Over the past six months, around 5% of the Fund's holdings were positively impacted by merger and acquisition (M&A) activity which aided our absolute returns.

Holdings that Contributed to Performance

Industrials have been an area of strength for the past six months. Our overweight position contributed and was bolstered by the performance of most of our larger holdings within the sector. Kansas City Southern, Albany International and Kaydon Corp., three of the Fund's ten largest overall holdings, outperformed both their peers as well as the overall benchmark.

Laidlaw International, a holding that we owned for a number of years, was one of the companies affected by M&A activity. While the deal had yet to close at period end, we liquidated the position and put some of the proceeds to work by taking small positions in truckload carriers such as Heartland Express, Knight Transportation and Celadon at prices well off their highs. These stocks have been under pressure due to capacity and pricing concerns in a slowing economy. However, we believe the balance sheet strength and experienced management teams at Heartland and Knight will enable the companies to bolster their positions in this type of environment, while we also believe Celadon has a nice growth opportunity in Mexico.

Holdings that Detracted from Performance

Oil and gas producer, Edge Petroleum, was our largest detractor during the period. The company's stock price fell as result of lower earnings in the first quarter, driven largely by lower natural gas prices and what we believe to be temporary production shortfalls. We feel comfortable with our position in the stock, given the possibility for long-term growth potential in natural gas and the company's January acquisitions, which we think will lead to a greater depth of drilling prospects going forward.

Another disappointment came from long-term holding Avocent, which makes analog and digital KVM (keyboard, video and mouse) switching systems used to manage multiple servers. In October of last year, we reported that our patience with Avocent had been rewarded. However, the company reported below-expected first-quarter 2007 earnings, due to softness in IT spending, project delays by some customers and a lower level of economic activity than the company had forecasted. We added to our position at prices near our original cost, as we believe Avocent's long term fundamentals remain positive.

Investment Strategy and Outlook

We plan to continue to take gains on stocks that approach our price targets, where we feel the risk/reward profile has deteriorated, and eliminate them when our price objective has been achieved. Over the last six months, our buys and sells have been, for the most part, balanced. However, given that relative valuations of small cap stocks are high and volatility levels are at multiple decade lows, we continue to have difficulty in becoming fully invested.

As always, our focus is on the long-term and the valuations of individual stocks. The slight pick-up in volatility during the last 12 months and during the period presented us with

(unaudited)

the opportunity to increase our equity exposure. In many cases these stocks have been stocks with growth potential that we believed were out of favor and/or were at the higher end of our capitalization spectrum, reflecting the underperformance and relative attractiveness of that ilk from a valuation standpoint. We believe that, in general, these equities offer better risk/reward relationships in the current market and will help us provide the positive consistent results to which we are accustomed.

Thank you for your continued investment in Janus Small Cap Value Fund.

Janus Core, Risk-Managed and Value Funds April 30, 2007 75

Notes to Schedules of Investments (unaudited)

Balanced Index				The Balanced Index is an internally calculated, hypothetical combination of unmanaged indices that combines the total returns from the S&P 500^® Index (55%) and the Lehman Brothers Government/Credit Index (45%).

Lehman Brothers Government/Credit Index				Is composed of all bonds that are investment grade with at least one year until maturity.

Lipper Large-Cap Core Funds				Funds that, by portfolio practice, invest at least 75% of their equity assets in companies with market capitalizations (on a three year weighted basis) greater than 300% of the dollar-weighted median market capitalization of the middle 1,000 securities of the S&P SuperComposite 1500 Index. Large-cap core funds have more latitude in the companies in which they invest. These funds typically have an average price-to-earnings ratio, price-to-book ratio, and three-year sales-per-share growth value, compared to the S&P 500^® Index.

Lipper Mid-Cap Value Funds				Funds that, by portfolio practice, invest at least 75% of their equity assets in companies with market capitalizations (on a three-year weighted basis) less than 300% of the dollar-weighted median market capitalization of the middle 1,000 securities of the S&P SuperComposite 1500 Index. Mid-cap value funds typically have a below-average price-to-earnings ratio, price-to-book ratio, and three-year sales-per-share growth value, compared to the S&P MidCap 400 Index.

Lipper Mixed-Asset Target Allocation Moderate Funds				Funds that, by portfolio practice, maintain a mix of between 40%-60% equity securities, with the remainder invested in bonds, cash, and cash equivalents.

Lipper Multi-Cap Core Funds				Funds that, by portfolio practice, invest in a variety of market capitalization ranges without concentrating 75% of their equity assets in any one market capitalization range over an extended period of time. Multi-cap funds typically have between 25% to 75% of their assets invested in companies with market capitalizations (on a three year weighted basis) above 300% of the dollar-weighted median market capitalization of the middle 1,000 securities of the S&P SuperComposite 1500 Index. Multi-cap core funds have more latitude in the companies in which they invest. These funds typically have an average price-to-earnings ratio, price-to-book ratio, and three-year sales-per-share growth value, compared to the S&P SuperComposite 1500 Index.

Lipper Small-Cap Core Funds				Funds that, by portfolio practice, invest at least 75% of their equity assets in companies with market capitalizations (on a three-year weighted basis) less than 250% of the dollar-weighted median of the smallest 500 of the middle 1,000 securities of the S&P SuperComposite 1500 Index. Small-cap core funds have more latitude in the companies in which they invest. These funds typically have an average price-to-earnings ratio, price-to-book ratio, and three-year sales-per-share growth value, compared to the S&P SmallCap 600 Index.

Morgan Stanley Capital International All Country World Index^SM				Is an unmanaged, free float-adjusted market capitalization weighted index composed of stocks of companies located in countries throughout the world. It is designed to measure equity market performance in global developed and emerging markets. The index includes reinvestment of dividends, net of foreign withholding taxes.

Russell 1000^® Growth Index				Measures the performance of those Russell 1000^® companies with higher price-to-book ratios and higher forecasted growth values.

Russell 2000^® Value Index				Measures the performance of those Russell 2000^® companies with lower price-to-book ratios and lower forecasted growth values.

Russell Midcap^®Index				The Russell Midcap^® Index measures the performance of the 800 smallest companies in the Russell 1000 Index.

Russell Midcap^® Value Index				Measures the performance of those Russell Midcap^® companies with lower price-to-book ratios and lower forecasted growth values.

S&P 500^® Index				The Standard & Poor's Composite Index of 500 stocks is a widely recognized, unmanaged index of common stock prices.

144A				Securities sold under Rule 144A of the Securities Act of 1933, as amended, are subject to legal and/or contractual restrictions on resale and may not be publicly sold without registration under the 1933 Act.

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Janus Balanced Fund, Janus Contrarian Fund, Janus Fundamental Equity Fund, Janus Growth and Income Fund, INTECH Risk-Managed Stock Fund, Janus Mid Cap Value Fund and Janus Small Cap Value Fund (collectively the "Funds" and individually a "Fund") are series funds. The Funds are part of Janus Investment Fund (the "Trust"), which was organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the "1940 Act") as an open-end management investment company. The Trust has thirty funds. Each of the Funds in this report is classified as diversified as defined in the 1940 Act, with the exception of Janus Contrarian Fund, which is classified as nondiversified. The Funds are no-load investments.

On April 21, 2003, Berger Small Cap Value Fund and Berger Mid Cap Value Fund (collectively the "Reorganizing Funds") participated in a tax-free reorganization with Janus Small Cap Value Fund and Janus Mid Cap Value Fund, respectively (collectively the "Value Funds"). Both the Reorganizing Funds and the Value Funds have Investor and Institutional Shares. The plan of reorganization provided for the transfer for assets and liabilities of the Reorganizing Funds to the Value Funds. The Value Funds were created to serve as "shells" for the transfer of net assets of the Reorganizing Funds. For accounting purposes, each Reorganizing Fund is considered the surviving entity, and the financial highlights shown for periods prior to April 30, 2003 are the financial highlights of the Reorganizing Funds. Subsequent to the reorganization, the Value Funds changed their fiscal year end from September 30 to April 30 and then to October 31.

Prior to April 21, 2003 Berger Mid Cap Value Fund was a series established under the Berger Investment Portfolio Trust, a Delaware business trust. Berger Small Cap Value Fund was the only portfolio established under the Berger Omni Investment Trust, a Massachusetts business trust. Berger Mid Cap Value Fund and Berger Small Cap Value Fund offered two separate classes of shares: Investor Shares and Institutional Shares. All classes of each fund had identical rights to earnings, assets and voting privileges. Effective March 31, 2000, both classes of Berger Small Cap Value Fund were closed to new investors. Berger Mid Cap Value Fund – Institutional Shares was also closed to new investors.

Expenses

Expenses are allocated daily to each class of shares based upon the ratio of net assets represented by each class as a percentage of total net assets. Expenses directly attributable to a specific class of shares are charged against the operations of such class. Each Fund bears expenses incurred specifically on its behalf and, in addition, each Fund bears a portion of general expenses, which may be based upon relative net assets of each class.

Securities Lending

State Street Bank and Trust Company (the "Lending Agent") may also invest the cash collateral in the State Street Navigator Securities Lending Prime Portfolio or investments in unaffiliated money market funds or accounts, mutually agreed to by the Funds and the Lending Agent, that comply with Rule 2a-7 of the 1940 Act relating to money market funds.

Interfund Lending

80 Janus Core, Risk-Managed and Value Funds April 30, 2007

Short Sales

The Funds, except INTECH Risk-Managed Stock Fund, may engage in "short sales against the box." Short sales against the box involve selling either a security that the Fund owns, or a security equivalent in kind and amount to the security sold short that the Fund has the right to obtain, for delivery at a specified date in the future. The Fund may enter into a short sale against the box to hedge against anticipated declines in the market price of portfolio securities. If the value of the securities sold short increases prior to the scheduled delivery date, the Fund loses the opportunity to participate in the gain.

The Funds, except INTECH Risk-Managed Stock Fund, may also engage in "naked" (uncovered) short sales. Naked short sales involve a Fund selling a security it does not own to a purchaser at a specified price. To complete the transaction, the Fund must borrow the security to deliver it to the purchaser and buy that same security in the market to return it to the lender. Although the potential for gain is limited to the difference between the price at which the Fund sold the security short and the cost of borrowing the security, its potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security. There is no assurance that the Fund will be able to close out a short position at a particular time or at an acceptable price. A gain or a loss will be recognized upon termination of a short sale. There is no limit on the size of any loss that a Fund may recognize upon termination of a short sale. Short sales held by the Fund are fully collateralized by other securities, which are denoted in the accompanying Schedule of Investments (if applicable). As of April 30, 2007, the Funds were not invested in short sales.

Forward Currency Transactions

The Funds may enter into forward currency contracts in order to reduce their exposure to changes in foreign currency exchange rates on their foreign portfolio holdings and to lock in the U.S. dollar cost of firm purchase and sale commitments for securities denominated in or exposed to foreign currencies. A forward currency exchange contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated rate. The gain or loss arising from the difference between the U.S. dollar cost of the original contract and the value of the foreign currency in U.S. dollars upon closing a contract is included in "Net realized gain/(loss) from foreign currency transactions" on the Statement of Operations (if applicable).

As of April 30, 2007, Janus Balanced Fund, Janus Contrarian Fund, Janus Fundamental Equity Fund and Janus Growth and Income Fund were invested in forward currency transactions.

Foreign Currency Translations

Bank Loans

Janus Balanced Fund may invest in bank loans, which include institutionally-traded floating rate securities generally acquired as an assignment or participation interest in loans originated by a bank or financial institution (the "Lender") that acts as agent for all holders. The agent administers the terms of the loan, as specified in the loan agreement. When investing in a loan participation, the Fund has the right to receive payments of principal, interest and any fees to which it is entitled only from the Lender selling the loan agreement and only upon receipt by the Lender of payments from the borrower. The Fund generally has no right to enforce compliance with the terms of the loan agreement with the borrower. Assignments and participations involve credit risk and liquidity risk. Interest rates on floating rate securities adjust with general interest rate changes and/or issuer credit quality. The interest rates paid on a floating rate security in which the Fund invests generally are readjusted every 45-60 days, on average, to an increment over a designated benchmark rate, such as the one-month, three-month, six-month, or one-year London Interbank Offered Rate ("LIBOR'').

The Fund may have difficulty trading assignments and participations to third parties. There may be restrictions on transfer and only limited opportunities may exist to sell such securities in secondary markets. As a result, the Fund may be unable to sell assignments or participations at the desired time or may be able to sell only at a price less than fair market value. The Fund utilizes an independent third party to value individual bank loans on a daily basis.

The average monthly value of borrowings outstanding under bank loan arrangements was $21,604,042 and the rate range was 1.75%-8.11375% during the six-month period ended April 30, 2007 for Janus Balanced Fund.

Futures Contracts

The Funds may enter into futures contracts. The Funds intend to use such derivative instruments to hedge or protect from adverse movements in securities prices, currency rates or interest rates. In addition, INTECH Risk-Managed Stock Fund may use futures contracts to gain exposure to the stock market pending investment of cash balances or to meet liquidity needs. The use of futures contracts may involve risks such as the possibility of illiquid markets or imperfect correlation between

Janus Core, Risk-Managed and Value Funds April 30, 2007 81

Notes to Financial Statements (unaudited) (continued)

the value of the contracts and the underlying securities, or that the counterparty will fail to perform its obligations.

As of April 30, 2007, INTECH Risk-Managed Stock Fund was the only Fund invested in futures contracts.

Options Contracts

The Funds may purchase or write put and call options on futures contracts or foreign currencies in a manner similar to that in which futures or forward contracts on foreign currencies will be utilized, and on portfolio securities for hedging purposes or as a substitute for an investment. The Fund generally invests in options to hedge against adverse movements in the value of portfolio holdings. In addition, INTECH Risk-Managed Stock Fund may use options contracts to gain exposure to the stock market for the pending investment of cash balances or to meet liquidity needs.

Holdings designated to cover outstanding written options are noted in the Schedule of Investments (if applicable). Options written are reported as a liability on the Statement of Assets and Liabilities (if applicable). Realized gains and losses are reported on the Statement of Operations (if applicable).The following Funds recognized realized gains or losses for written options during the six-month period ended April 30, 2007.

When-issued Securities

Equity-Linked Structured Notes

The Funds may invest in equity-linked structured notes. Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or nonregistered form. An investment in equity-linked structured notes creates exposure to the credit risk of the issuing financial institution, as well as to the market risk of the underlying securities. There is no guaranteed return of principal with these securities and the appreciation potential of these securities may be limited by a maximum payment or call right. In certain cases, equity-linked structured notes may be more volatile and less liquid than less complex securities or other types of fixed-income securities. Such securities may exhibit price behavior that does not correlate with other fixed-income securities). As of April 30, 2007, the Janus Growth and Income Fund was invested in equity-linked structured notes.

Initial Public Offerings

Additional Investment Risk

The Funds, particularly Janus Balanced Fund, may be invested in lower-rated debt securities that have a higher risk of default or loss of value since these securities may be sensitive to economic changes, political changes or adverse developments specific to the issuer. INTECH Risk-Managed Stock Fund does not intend to invest in high-yield/high-risk bonds.

Restricted Security Transactions

Restricted Cash

As of April 30, 2007, Janus Contrarian Fund had restricted cash in the amount of $94,881,150. The restricted cash represents funds in relation to options contracts invested by Janus Contrarian Fund at April 30, 2007. The restricted cash is held at the Fund's custodian, State Street Bank and Trust Company. The carrying value of the restricted cash approximates fair value.

Dividend Distributions

Dividends for Janus Balanced Fund and Janus Growth and Income Fund are declared and distributed quarterly, and capital gains (if any) are distributed annually. The remaining Funds generally declare and distribute dividends of net investment income and capital gains (if any) annually. The majority of dividends and capital gains distributions from a Fund will be automatically reinvested into additional shares of that Fund, based on the discretion of the shareholder.

2. INVESTMENT ADVISORY AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

Each Fund pays a monthly advisory fee to Janus Capital based upon average daily net assets and calculated at the annual rate shown in the table below for each Fund.

Fund	Average Daily Net Assets of Fund	Management Fee (%)
Core
Janus Balanced Fund	All Asset Levels		0.55
Janus Contrarian Fund	All Asset Levels		0.64
Janus Fundamental Equity Fund⁽¹⁾	All Asset Levels		0.60
Janus Growth and Income Fund	All Asset Levels		0.62

Value
Janus Mid Cap Value Fund	All Asset Levels		0.64
Janus Small Cap Value Fund	All Asset Levels		0.72

(1) Formerly named Janus Core Equity Fund.

For Janus Contrarian Fund, INTECH Risk-Managed Stock Fund and Janus Mid Cap Value Fund, the investment advisory fee is determined by calculating a base fee and applying a performance adjustment. The base fee rate is the same as the investment advisory fee rate shown in the table above. The performance adjustment either increases or decreases the base fee depending on how well each Fund has performed relative to its benchmark, as shown below:

Fund				Benchmark Index
Janus Contrarian Fund				S&P 500^® Index
INTECH Risk-Managed Stock Fund				S&P 500^® Index
Janus Mid Cap Value Fund				Russell Midcap^®
				Value Index

Only the base fee rate applied until January 2007 for INTECH Risk-Managed Stock Fund, and until February 2007 for Janus Contrarian Fund and Janus Mid Cap Value Fund, at which time the calculation of the performance adjustment is applied as follows:

(Investment Advisory Fee = Base Fee +/- Performance Adjustment).

The investment advisory fee paid to Janus Capital by each of the Funds listed above consists of two components: (i) a base fee calculated by applying the contractual fixed-rate of the advisory fee to the Fund's average daily net assets during the previous month ("Base Fee"), plus or minus (ii) a performance-fee adjustment ("Performance Adjustment") calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund's average daily net assets during the applicable performance measurement period.

The performance measurement period generally is the previous 36 months, although no Performance Adjustment will be made until a Fund's performance-based fee structure has been in effect for at least 12 months. When a Fund's performance-based fee structure has been in effect for at least 12 months, but less than 36 months, the performance measurement period will be equal to the time that has elapsed since the performance-based fee structure took effect. As noted above, any Performance Adjustment began January 2007 for INTECH Risk-Managed Stock Fund and February 2007 for Janus Contrarian Fund and Janus Mid Cap Value Fund. No Performance Adjustment will be applied unless the difference between the Fund's investment performance and the investment record of the Fund's benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. Because the Performance Adjustment is tied to a Fund's relative performance to its benchmark index (and not its absolute performance), the Performance Adjustment could increase Janus Capital's fee even if the Fund's shares lose value during the performance measurement period and could decrease Janus Capital's fee even if the Fund's shares increase in value during the performance measurement period. For purposes of computing the Base Fee and the Performance Adjustment, net assets will be averaged over different periods (average daily net assets during the previous month for the Base Fee, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of a Fund is calculated net of expenses whereas a Fund's benchmark index does not have any expenses.

84 Janus Core, Risk-Managed and Value Funds April 30, 2007

Reinvestment of dividends and distributions are included in calculating both the performance of a Fund and the Fund's benchmark index. The Base Fee is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued evenly each day throughout the month. The investment fee is paid monthly in arrears.

The investment performance of Janus Mid Cap Value Fund's Investor Shares ("Investor Shares") for the performance measurement period will be used to calculate the Performance Adjustment. After Janus Capital determines whether a particular Fund's performance was above or below its benchmark index by comparing the investment performance of the Investor Shares for the Fund against the investment record of that Fund's benchmark index, Janus Capital will apply the same Performance Adjustment (positive or negative) across each other class of shares of the Fund. It is not possible to predict the effect of the Performance Adjustment on future overall compensation to Janus Capital since it will depend on the performance of each Fund relative to the record of the Fund's benchmark index and future changes to the size of each Fund. The Funds' prospectus and statement of additional information contains additional information about performance-based fees. The amount shown as Advisory fees on the Statement of Operations reflects the base fee plus/minus any performance adjustment.

Enhanced Investment Technologies, LLC ("INTECH") serves as subadviser to INTECH Risk-Managed Stock Fund. Janus Capital indirectly owns approximately 86.5% of the outstanding voting shares of INTECH. Janus Capital pays INTECH a subadvisory fee at the annual rate of 0.26% of average daily net assets from its management fee for managing the Fund.

Perkins, Wolf, McDonnell and Company, LLC ("Perkins") serves as subadviser to Janus Mid Cap Value Fund and Janus Small Cap Value Fund. As compensation for its services, Perkins receives, directly from each Value Fund, a fee equal to 50% of Janus Capital's management fee (net of any reimbursement of expenses incurred or fees waived by Janus Capital). Janus Capital has a 30% ownership stake in Perkins' investment advisory business.

Janus Services LLC ("Janus Services"), a wholly-owned subsidiary of Janus Capital, receives an administrative services fee at an annual rate of up to 0.05% of the average daily net assets of INTECH Risk-Managed Stock Fund, Janus Mid Cap Value Fund and Janus Small Cap Value Fund for providing or procuring recordkeeping, subaccounting and other administrative services to the investors.

Each of the Funds pays Janus Services an asset-weighted average annual fee based on the proportion of each Fund's total net assets sold directly and the proportion of each Fund's net assets sold through financial intermediaries. The applicable fee rates are 0.16% of net assets on the proportion of assets sold directly and 0.21% on the proportion of assets sold through intermediaries. In addition, Janus Services receives $4.00 per open shareholder account (excluding Janus Mid Cap Value Fund - Institutional Shares and Janus Small Cap Value Fund) for transfer agent services.

By written agreement, Janus Services has agreed until March 1, 2008 to waive the transfer agency fee payable so that the total operating expenses (excluding extraordinary expenses and the 0.05% administrative services fee) by the Institutional Shares of Janus Mid Cap Value Fund and Janus Small Cap Value Fund do not exceed 0.77% and 0.79%, respectively. Amounts waived by Janus Capital are disclosed as Excess Expense reimbursement on the Statement of Operations.

A 2.00% redemption fee may be imposed on shares of INTECH Risk-Managed Stock Fund held for three months or less. Effective with purchases on and after May 15, 2007, a 2% redemption fee may be imposed on shares held for 90 days or less. This fee is paid to the Fund rather than Janus Capital, and is designed to deter excessive short-term trading and to offset the brokerage commissions, market impact, and other costs associated with changes in the Fund's asset level and cash flow due to short-term money movements in and out of the Fund. The redemption fee is accounted for as an addition to Paid-in Capital. Total redemption fees received by INTECH Risk-Managed Stock Fund were $55,688 for the six-month period ended April 30, 2007.

These non-recurring costs were allocated to all Portfolios based on the Portfolios' respective net assets as of July 31, 2004. No fees were allocated to Janus Global Research Fund, Janus Triton Fund and the Janus Smart Portfolios as the funds commenced operations after July 31, 2004. Additionally, all future non-recurring costs will be allocated to all Portfolios based upon the Portfolios' respective net assets on July 31, 2004.

Certain officers of the Funds may also be officers and/or directors of Janus Capital. Such officers receive no compensation from the Funds, except for the Funds' Chief Compliance Officer. Effective January 1, 2006, the Funds began reimbursing the adviser for a portion of the compensation paid to the Chief Compliance Officer of the Funds. Total compensation of $56,756 was paid by the Trust during the six-month period ended April 30, 2007. The Funds' portion is reported as part of "Other Expenses" on the Statement of Operations.

Additional Information (unaudited) (continued)

quality of those services had been consistent with or superior to quality norms in the industry; and that the Funds were likely to benefit from the continued provision of those services. They also concluded that Janus Capital and each subadviser had sufficient personnel, with the appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract and retain well-qualified personnel.

Performance of the Funds

Costs of Services Provided

The Trustees reviewed information on the profitability of Janus Capital and its affiliates of their relationships with each Fund, as well as an explanation of the methodology utilized in allocating various expenses among the Funds and other clients. The Trustees also reviewed the financial statements of Janus Capital's parent company and its corporate structure. In their review, the Trustees considered whether Janus Capital and each subadviser receive adequate incentives to manage the Funds effectively. The Trustees recognized that profitability comparisons among investment advisers are difficult because very little comparative information is publicly available and profitability of any adviser is affected by numerous factors, including the organizational structure of the particular manager, the types of funds and other accounts it manages, possible other lines of business, the methodology for allocating expenses and the Adviser's capital structure and cost of capital. However, based on the information available and taking those factors into account, the Trustees concluded that Janus Capital's profitability with respect to each Fund in relation to the services rendered was not unreasonable.

The Trustees concluded that the management fees and other compensation payable by each Fund to Janus Capital and its affiliates, as well as the fees paid by Janus Capital to the

92 Janus Core, Risk-Managed and Value Funds April 30, 2007

subadvisers of subadvised Funds, were reasonable in relation to the nature and quality of the services provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies and the fees Janus Capital and the subadviser charge to other clients. The Trustees also concluded that the overall expense ratio of each Fund was reasonable, taking into account the size of the Fund, the quality of services provided by Janus Capital and any subadviser, the investment performance of the Fund and any expense limitations agreed to by Janus Capital.

Economies of Scale

Other Benefits to Janus Capital

The Trustees also considered benefits that accrue to Janus Capital and its affiliates from their relationships with the Funds. They recognized that two affiliates of Janus Capital separately serve the Funds as transfer agent and distributor, respectively, and that the transfer agent receives compensation directly from the non-money market Funds for services provided. The Trustees also considered Janus Capital's past and proposed use of commissions paid by the Funds on their portfolio brokerage transactions to obtain proprietary research products and services benefiting those Funds and/or other clients of Janus Capital, as well as Janus Capital's prior agreement not to use any Fund's brokerage transactions to obtain third party research products or services. The Trustees concluded that Janus Capital's use of "soft" commission dollars of a Fund to obtain proprietary research products and services was consistent with regulatory requirements and guidelines and was likely to benefit the Funds. The Trustees also concluded that, other than the services provided by Janus Capital and its affiliates pursuant to the agreements and the fees to be paid by each Fund therefor, the Funds and Janus Capital may potentially benefit from their relationship with each other in other ways. They concluded that Janus Capital benefits from the receipt of proprietary research products and services acquired through commissions paid on portfolio transactions of the Funds and that the Funds benefit from Janus Capital's receipt of those products and services as well as research products and services acquired through commissions paid by other clients of Janus Capital. They further concluded that success of any Fund could attract other business to Janus Capital or other Janus funds and that the success of Janus Capital could enhance Janus Capital's ability to serve the Funds.

Useful Information About Your Fund Report

Management Commentaries

Fund Expenses

We believe it's important for our shareholders to have a clear understanding of Fund expenses and the impact they have on investment return.

Example

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including redemption fees (and any related exchange fees) and (2) ongoing costs, including management fees and other Fund expenses. The example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the six-month period from November 1, 2006 to April 30, 2007.

Actual Expenses

The first line of the table in each example provides information about actual account values and actual expenses. You may use the information in this line, 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 first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during the period.

Hypothetical Example for Comparison Purposes

Janus Capital Management LLC ("Janus Capital") has contractually agreed to waive Janus Global Research Fund's total operating expenses, excluding brokerage commissions, interest, taxes and extraordinary expenses, to certain limits until at least March 1, 2008. Expenses in the example reflect the application of this waiver. Had the waiver not been in effect, your expenses would have been higher. More information regarding the waiver is available in the Funds' prospectuses.

Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as redemption fees. These fees are fully described in the prospectus. Therefore, the second line of each table 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 transaction costs were included, your costs would have been higher.

Performance Overview

For the six months ending April 30, 2007, Janus Global Opportunities Fund gained 17.08%, outperforming its benchmark, the Morgan Stanley Capital International (MSCI) World Index^SM, which advanced 11.87%.

Equity markets around the globe delivered healthy gains during the period amid continued evidence of strong economic growth and modest inflation. After a brief period of market volatility in late February and early March, markets rebounded quickly and many indexes posted double-digit gains. While U.S. corporate profit growth showed signs of slowing, robust mergers and acquisitions (M&A) and private equity transactions continued to provide key valuation support to equities in the U.S. and around the world.

Holdings that Contributed to Performance

Within the Fund, holdings in the consumer discretionary and consumer staples sectors drove performance, relative to the benchmark.

Among consumer discretionary positions, Amazon.com advanced as our thesis for investing in the U.S.-based online retailer played out. While the rest of the market fretted over higher operational investments that resulted in lower profits, we believed this was a short-term issue. Over the past six months, the slowdown in Amazon's spending started to materialize and the resulting operating leverage contributed largely to strong profits and cash flow levels. The company also announced its first share buyback, which should further enhance returns going forward. Despite a nearly 38% rise in the stock, we believe Amazon was attractively valued and we maintained our position at period-end.

Another consumer discretionary position, international cable television system operator Liberty Global, contributed significantly. A business with historically robust cash flow stemming from millions of cable television subscribers, the stock benefited from market enthusiasm for management's share buyback during the period. Additionally, as European M&A activity heightened, the private market valuations on recent deals within the cable space suggested that the company's shares were still attractively valued.

Apparel company Esprit Holdings of Hong Kong added to gains as it continued to grow rapidly. An increasingly-established brand in Europe, the company expanded in under-penetrated markets such as Germany, France and Spain. Solid execution has translated into strong earnings and we were rewarded for our conviction in this position.

Holdings that Detracted from Performance

Diminishing relative returns were select investments in the financials, industrials and information technology sectors.

Two Japanese consumer lending companies, Promise Company and Acom Company, were among those that weighed on the financials sector. Shares of both companies lagged the market amid rising concerns that new government regulations may pose a future risk to the historically high-margin unsecured lending business. Fundamentally, we believe the companies should continue to maintain healthy margins, albeit lower than before the new regulations came into effect. In our opinion, shares may continue to be pressured in the near future by cautious investor sentiment.

Multifaceted conglomerate Berkshire Hathaway also ranked among the Fund's largest detractors during the period. Considering its run-up in the preceding six months, it was not surprising to see some weakness in the shares as investors took profits. We continue to believe this holding represents an attractive risk/reward.

Outlook

With equity indexes around the world near multi-year or all-time highs at the end of the period, we are closely monitoring several fundamental factors for directional cues. First, despite the weakness in the U.S. housing sector and the associated credit quality issues in the subprime mortgage market, the U.S. economy has remained healthy. Should any signs of a U.S. slowdown appear, markets around the world could experience an adverse reaction. Second, corporate M&A and private equity transactions, which have supported higher equity valuations in the U.S., have swept into Europe and contributed to higher prices there. While watching

Janus Global Research Fund (unaudited)

Ticker: JARFX

Fund Snapshot

This fund pulls together the best ideas from Janus' research analysts into a single package.

Team-Based Approach
Led by Jim Goff,
Director of Research

Performance Overview

For the six-month period ended April 30, 2007, Janus Global Research Fund gained 16.87%, outgaining the 11.55% return posted by its primary benchmark, the Morgan Stanley Capital International (MSCI) World Growth Index and the 9.10% return of its secondary benchmark, the Russell 1000^® Index.

Equity markets around the globe delivered healthy gains during the period amid continued evidence of strong economic growth and modest inflation. International markets outperformed the U.S. market during the period. After a brief period of market volatility in late February and early March, stocks rebounded strongly, and many indexes posted double-digit gains. While U.S. corporate profit growth showed signs of slowing, robust merger and acquisition (M&A) activity and private equity transactions continued to provide key valuation support to equities in the U.S. and around the world.

There are two primary factors that drive the basic character and composition of a mutual fund. The first is its prospectus, or investment guidelines, which defines allowable areas of investment. Janus Global Research Fund's broad investment guidelines allow us to invest in what we believe to be the most attractive equity markets in the world. The second driver is the portfolio manager, whose specific criteria or investment style normally determines which types of stocks are favored for investment. In the case of Janus Global Research Fund, the research analyst team at Janus directly drives the portfolio. We believe that this approach allows consideration of more ideas and styles than management by a single portfolio manager would permit. We also believe that the Fund's high level of diversification across individual holdings, sectors, market caps and geographies is the result of this method, thereby supporting our objective to generate strong investment returns while managing risk through diversification.

Janus Global Research Fund is managed to be sector neutral, meaning that the Fund's exposure to different sectors is approximately equal to that of the benchmark. The Fund relies on the strength of our research analysts' stock selections in seeking to generate superior performance, rather than making sector bets. Accordingly, our research and investment process focuses on finding the best ideas within each sector, rather than trying to guess which sectors will perform best in any given period. For the six-month period ended April 30, 2007, each of our eight sector teams outperformed the corresponding portion of the benchmark.

Discussion of Individual Holdings that Contributed to Fund Performance

While this discussion may be less relevant here than for most funds due to the nature of Janus Global Research Fund, we believe it is worthwhile to recognize why the Fund was able to outperform its benchmark during the period. The Fund is not only diversified across sectors, but also individual holdings. As of 4/30/07, the Fund held 120 stocks with the top 10 securities representing only around 17% of the Fund's net assets. This low level of concentration means that it is not likely that the returns of one or even a handful of stocks drove the fortunes of the Fund. The important thing, however, is that winners far outnumbered losers.

Holdings that Benefited Fund Performance

Within the Fund, positions in the materials and financials sectors provided the largest contributions to relative performance during the period. Our top seven contributors to performance during the period were Owens-Illinois, Companhia Vale Rio Doce (CVRD), CapitaLand, Potash Corporation of Saskatchewan, Reliance Industries, NRG Energy and Suntech Power Holdings. This list of securities represents seven different sectors, thereby highlighting the diversity of the Fund.

Owens-Illinois led all individual performers during the period. The company benefited from investor optimism that new CEO Al Stroucken's focus on pricing and cost reductions may drive margin growth. This thesis gained credibility midway through the period as the company put its solidly performing – but non-core – plastics packaging business up for sale.

Brazilian iron ore producer, CVRD, also contributed to performance. A key supplier to booming infrastructure markets in India and China, the company fell out of favor when it announced plans to purchase Canadian nickel producer, Inco, in August 2006. By the period's close, however, the markets had warmed to the fact that the deal effectively diversified CVRD's revenues beyond iron ore and could enhance earnings.

Janus International & Global Funds April 30, 2007 11

Janus Global Research Fund (unaudited)

A top performer from the financials space, Singapore-based real estate developer, CapitaLand, added significantly to gains. In addition to a beneficial supply/demand environment in Singapore, we believe the company is also well-positioned to profit from the expected growth of real estate opportunities across Asia.

Holdings that Detracted from Fund Performance

Our biggest detractors included optionsXpress Holdings, Whole Foods Market, Nissan Motor, Varian Medical Systems, Melco International Development, SanDisk and SiRF Technology Holdings.

From an individual security standpoint, the poorest performer was online options trading platform operator, optionsXpress. The company faced persistent challenges in adding new accounts, even during the traditionally busy first quarter, but we still believe the stock offers a very attractive risk/reward and added to the position.

Another laggard was organic food retailer, Whole Foods Market. The stock dropped amid reduced same-store sales reports, and lowered expectations going forward. Displeased with developments, we liquidated our stake.

Outlook

We would caution investors that our recent investment returns, both on an absolute basis and relative to the market, were unsustainably high and should not be expected to continue at such a high level. Simply put, though, we are excited about Janus Global Research Fund. We are pleased not only with our performance during the period, but also with how we achieved it – through outperformance by each of our eight sector teams. Long term, we are optimistic about our ability to potentially produce market-beating returns due to the strength of the Janus research team and a consistent and repeatable investment process that seeks to produce a well-diversified portfolio of best ideas. The Fund attempts to add value through research, and to manage risk through diversification, in an effort to produce strong risk-adjusted returns for our investors. We appreciate your investment in the Fund, and we are committed as substantial investors alongside of you.

The Fund has a performance-based management fee that adjusts upward or downward based on the Fund's performance relative to an approved benchmark index over a performance measurement period.

The Fund's expense ratios were determined based on average net assets as of the fiscal year ended October 31, 2006. Detailed information is available in the prospectus. Contractual waivers agreed to by Janus Services LLC are included under "Net Annual Fund Operating Expenses." All expenses are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

Foreign investing involves special risks such as currency fluctuations and political uncertainty.

There is no assurance that the investment process will consistently lead to successful investing.

Net dividends reinvested are the dividends that remain to be reinvested after foreign tax obligations have been met. Such obligations vary from country to country.

Effective December 31, 2006, Janus Research Fund changed its name to "Janus Global Research Fund" and adopted an additional investment strategy to normally invest at least 40% of its net assets in securities of issuers from different countries located throughout the world, excluding the United States.

See Notes to Schedules of Investments for index definitions.

Effective January 1, 2007, the Fund changed its primary benchmark from the Russell 1000^® Index to the Morgan Stanley Capital International ("MSCI") World Growth Index. The new benchmark provides a more appropriate representation of the Fund's investments. The benchmark index is used to calculate the Fund's performance-based fee adjustment to the investment advisory fee for periods after January 1, 2007.

Fund Snapshot

This growth fund invests in overseas companies based on their individual merits regardless of their geography or industry sector.

Brent Lynn
portfolio manager

Performance Overview

For the six months ended April 30, 2007, Janus Overseas Fund gained 18.92%. The Fund's primary benchmark, the Morgan Stanley Capital International (MSCI) EAFE^® Index, advanced 15.46%, and its secondary benchmark, the MSCI All Country World ex-U.S. Index^SM, appreciated 15.89%.

Equity markets around the globe delivered healthy gains during the period amid continued evidence of reasonable economic growth and modest inflation. After a brief period of market volatility in late February and early March, markets rebounded quickly and many indexes posted double-digit gains for the period. While the U.S. economy showed signs of slowing, many other key countries showed signs of economic strength. Robust merger and acquisition (M&A) activity and private equity transactions continued to provide valuation support to equities in the U.S. and around the world. Among emerging markets, China continued to be a top performer, backed by double-digit economic growth rates and strong local Chinese investor demand for equities.

Strong Performers Included Materials and Consumer Discretionary

Within the Fund, holdings in the materials and consumer discretionary sectors were among those that led performance, relative to the benchmark.

Brazilian iron ore producer Companhia Vale do Rio Doce (CVRD), a materials holding, was the leading individual performer during the period. Steel demand in China and other emerging economies was a key driver of growth for CVRD. The company purchased Canadian nickel producer Inco in January 2007. I believe that the acquisition of Inco will enhance CVRD's earnings power, diversify its mining assets and create significant synergies in its nickel business.

Another key contributor within the materials space was Canadian fertilizer company, Potash Corporation of Saskatchewan. As the world's largest potash fertilizer company and also a large producer of phosphate and nitrogen fertilizers, I believe Potash Corp is well positioned to benefit from higher agricultural product prices and increased fertilizer usage.

Japanese electronics manufacturer Sony, a consumer discretionary name, also contributed to performance. Despite a high-profile recall of laptop batteries and marketplace uncertainties over its PlayStation^® 3 (PS3) game console, I believe the company's restructuring effort is gaining traction and the consumer electronics business is improving.

Select Information Technology (IT), Industrials and Consumer Staples Weighed on Performance

From a sector perspective, detractors included IT, industrials and consumer staples.

In the IT space, Silicon-On-Insulator Technologies (SOITEC), the French innovator of silicon-on-insulator wafer technology for semiconductor chips, lagged amid concerns over near-term customer demand. Despite near-term issues, I believe SOITEC's technology will gain traction in a wider variety of semiconductors over time.

Another detractor was Macau gaming company Melco International Development. Macau is rapidly becoming the gaming capital of Asia. Despite some cost overruns and delays in the construction of its Crown Macau casino, I continue to believe that Melco is well positioned to capitalize on the rapid growth in Asian gaming.

Additionally, Indian sugar producer Bajaj Hindusthan underperformed as sugar prices came off 2006 highs. Looking forward, I believe that sugar demand will expand due to ethanol growth worldwide and increased sugar consumption in emerging markets.

Outlook

With many equity indexes around the world near multi-year or all-time highs, I am naturally monitoring the global market closely. During the past six months, the markets and the Fund performed well. I consider six months to be a short length of time, and in future six-month periods, the performance of the Fund may certainly be worse or even negative. Throughout turbulent markets, I have not changed my investment approach. I believe the best way to generate great long-term returns is to make high conviction, long-term investments in world-class companies with exciting growth prospects trading at undeservedly low valuations. As manager of the Fund, my

Foreign investing involves special risks such as currency fluctuations and political uncertainty.

The Fund held approximately 13.0% of its assets in Brazilian securities as of April 30, 2007 and the Fund has experienced significant gains due, in part, to its investments in Brazil. While holdings are subject to change without notice, the Fund's returns and NAV may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in Brazil.

May 5, 1994 is the date used to calculate the since-inception Lipper ranking, which is slightly different from when the Fund began operations since Lipper provides fund rankings as of the last day of the month or the first Thursday after fund inception.

There is no assurance that the investment process will consistently lead to successful investing.

The Fund will invest at least 80% of its net assets in the type of securities described by its name.

Net dividends reinvested are the dividends that remain to be reinvested after foreign tax obligations have been met. Such obligations vary from country to country.

Fund Snapshot

This global fund offers geographic diversification in a single portfolio.

Jason Yee
portfolio manager

For the six months ending April 30, 2007, Janus Worldwide Fund advanced 15.34%, outpacing its benchmark, the Morgan Stanley Capital International (MSCI) World Index^SM, which returned 11.87%.

Equity markets around the globe delivered healthy gains during the period amid continued evidence of strong economic growth and modest inflation. After a brief period of market volatility in late February and early March, markets rebounded quickly and many indexes posted double-digit gains. While U.S. corporate profit growth showed signs of slowing, robust merger and acquisition (M&A) activity and private equity transactions continued to provide key valuation support to equities in the U.S. and around the world.

Select Holdings that Contributed to Fund Performance

Within the Fund, holdings in the consumer discretionary, healthcare and materials sectors led performance, relative to the benchmark.

Among consumer discretionary positions, Amazon.com contributed significantly as my thesis for investing in the U.S.-based online retailer played out. While the rest of the market fretted over higher capital investments that resulted in lower profits, I believed this was a short-term issue. Over the past six months, the slowdown in Amazon's spending started to materialize and the resulting operating leverage contributed largely to strong profits and cash flow. The company also announced its first share buyback, which should further enhance returns going forward. Despite a nearly 38% rise in the stock, I believe Amazon was attractively valued and I maintained the Fund's position at period end.

Another consumer discretionary company, specialty retailer Esprit Holdings of Hong Kong, added to gains as it continued to grow rapidly. An increasingly-established brand in Europe, the company is expanding in under-penetrated markets such as Germany, France and Spain. Solid execution translated into strong earnings and I was rewarded for my conviction in this position.

A healthcare position that contributed to performance was U.S. pharmacy benefit manager Medco Health Solutions. Over the long haul, I expect this business to benefit from the increasing use of generic drugs by U.S. consumers, operating leverage and strong free cash flow generation. During the period, my stake appreciated as a bidding war broke out over competitor Caremark. Drugstore operator CVS eventually won the right to purchase Caremark, which I believe left Medco well positioned as the sole pharmacy benefit manager in the U.S. devoted to this line of business.

Holdings that Detracted from Performance

The Fund's consumer discretionary performance was curtailed somewhat by three U.S. homebuilders that ranked among the largest detractors during the period. Centex, Lennar and Pulte Homes all declined on concerns about the upcoming spring home-selling season, lingering worries that defaults on subprime mortgages will drive existing home inventories higher and overall weak fundamentals in the industry. I believed, however, that with prices near book value, the companies were undervalued. Furthermore, I feel each is poised to outperform to the extent that the Federal Reserve decides to reduce short-term interest rates.

Further diminishing relative returns were investments in the industrials and telecommunication services sectors.

Outlook

With equity indexes around the world near multi-year or all-time highs at the end of the period, we are closely monitoring several fundamental factors for directional cues. First, despite the weakness in the U.S. housing sector and the associated credit quality issues in the subprime mortgage market, the U.S. economy has remained healthy. Should any signs of a U.S. slowdown appear, I believe markets around the world could experience an adverse reaction. Second, corporate M&A and private equity transactions, which have supported higher

(unaudited)

equity valuations in the U.S., have swept into Europe and contributed to higher prices there. While watching developments on the economic and liquidity fronts, I will continue to adhere to my rigorous stock selection process in order to identify promising investments that may be trading at a discount to their intrinsic value.

and characteristic information

The Fund has a performance-based management fee that adjusts upward or downward based on the Fund's performance relative to an approved benchmark index over a performance measurement period.

For the period from July 1, 2006 through January 31, 2007 (''Waiver Period''), Janus Capital contractually agreed to waive its right to receive a portion of the Fund's base management fee, at the annual rate of up to 0.15% of average daily net assets, under certain conditions. This waiver was applied for any calendar month in the Waiver Period if the total return performance of the Fund for the period from February 1, 2006 through the end of the preceding calendar month, calculated as though there had been no waiver of the base management fee, was less than performance of the Fund's primary benchmark index for that period.

The Fund's expense ratios were determined based on net average assets as of the fiscal year ended October 31, 2006. Detailed information is available in the prospectus. All expenses are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

Foreign investing involves special risks such as currency fluctuations and political uncertainty.

There is no assurance that the investment process will consistently lead to successful investing.

Net dividends reinvested are the dividends that remain to be reinvested after foreign tax obligations have been met. Such obligations vary from country to country.

When-issued Securities

Equity-Linked Structured Notes

The Funds may invest in equity-linked structured notes. Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or nonregistered form. An investment in equity-linked structured notes creates exposure to the credit risk of the issuing financial institution, as well as to the market risk of the underlying securities. There is no guaranteed return of principal with these securities and the appreciation potential of these securities may be limited by a maximum payment or call right. In certain cases, equity-linked structured notes may be more volatile and less liquid than less complex securities or other types of fixed-income securities. Such securities may exhibit price behavior that does not correlate with other fixed-income securities. As of April 30, 2007, the Funds were not invested in equity-linked structured notes.

Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

2. INVESTMENT ADVISORY AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

Each Fund pays a monthly advisory fee to Janus Capital based upon average daily net assets and calculated at the annual rate of 0.64% (0.60% for Janus Worldwide Fund).

For Janus Global Research Fund and Janus Worldwide Fund, the investment advisory fee is determined by calculating a base fee and applying a performance adjustment. The base fee rate is the same as the investment advisory fee rate shown in the previous paragraph. The performance adjustment either increases or decreases the base fee depending on how well each Fund has performed relative to its benchmark, as shown below:

Fund				Benchmark Index
Janus Global Research Fund⁽¹⁾				MSCI World Growth Index⁽²⁾
Janus Worldwide Fund				MSCI World Index^SM

(1) Formerly named Janus Research Fund.

(2) Effective January 1, 2007, Janus Global Research Fund's benchmark changed from the Russell 1000^® Index to the MSCI World Growth Index for purposes of measuring the Fund's performance and calculating the performance adjustment.

Only the base fee rate applied until January 2007 for Janus Global Research Fund and February 2007 for Janus Worldwide Fund, at which time the calculation of the performance adjustment is applied as follows:

(Investment Advisory Fee = Base Fee +/- Performance Adjustment).

The investment advisory fee paid to Janus Capital by Janus Global Research Fund and Janus Worldwide Fund consists of two components: (i) a base fee calculated by applying the contractual fixed-rate of the advisory fee to the Fund's average daily net assets during the previous month ("Base Fee"), plus or minus (ii) a performance-fee adjustment ("Performance Adjustment") calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund's average daily net assets during the applicable performance measurement period.

The performance measurement period generally is the previous 36 months, although no Performance Adjustment will be made until the Fund's performance-based fee structure has been in effect for at least 12 months. When the Fund's performance-based fee structure has been in effect for at least 12 months, but less than 36 months, the performance measurement period will be equal to the time that has elapsed since the performance-based fee structure took effect. As noted above, any Performance Adjustment began January 2007 for Global Research Fund and February 2007 for Janus Worldwide Fund. No Performance Adjustment will be applied unless the difference between the Fund's investment performance and the investment record of the Fund's benchmark indices are 0.50% or greater (positive or negative) during the applicable performance measurement period. For Janus Global Research Fund, the Performance Adjustment is made in even increments for every 0.50% difference in the investment performance of the Fund compared to the cumulative investment record of the Russell 1000^® Index (for periods prior to January 1, 2007) and the MSCI World Growth Index (for periods commencing January 1, 2007). The aggregate of the Fund's performance

Janus International & Global Funds April 30, 2007 45

Notes to Financial Statements (unaudited) (continued)

versus these two benchmark indices, respectively, are used for purposes of calculating the Performance Adjustment. Because the Performance Adjustment is tied to the Fund's relative performance to its benchmark index (and not its absolute performance), the Performance Adjustment could increase Janus Capital's fee even if the Fund's shares lose value during the performance measurement period and could decrease Janus Capital's fee even if the Fund's shares increase in value during the performance measurement period. For purposes of computing the Base Fee and the Performance Adjustment, net assets will be averaged over different periods (average daily net assets during the previous month for the Base Fee, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of a Fund is calculated net of expenses whereas a Fund's benchmark index does not have any expenses. Reinvestment of dividends and distributions are included in calculating both the performance of a Fund and the Fund's benchmark index. The Base Fee is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued evenly each day throughout the month. The investment fee is paid monthly in arrears.

The Funds' prospectus and statement of additional information contains additional information about performance-based fees. The amount shown as Advisory fees on the Statement of Operations reflects the base fee plus/minus any performance adjustment.

Effective for the period from July 1, 2006 through January 31, 2007 ("Waiver Period") for Janus Worldwide Fund, Janus Capital contractually agreed to waive its right to receive a portion of the Fund's advisory fee, at the annual rate of up to 0.15% of average daily net assets, under certain conditions. This waiver applied for any calendar month in the Waiver Period if the Fund's performance for the period from February 1, 2006 through the end of the preceding calendar month, calculated as though there had been no waiver of the advisory fee, was less than benchmark performance for that period.

Until at least March 1, 2008, provided that Janus Capital remains investment adviser to the Funds, Janus Capital has agreed to reimburse Janus Global Research Fund by the amount, if any, that such Fund's normal operating expenses in any fiscal year, including the investment advisory fee, but excluding brokerage commissions, interest, taxes and extraordinary expenses, exceed the annual rate of 1.25%. If applicable, amounts reimbursed to the Fund by Janus Capital are disclosed as Excess Expense Reimbursement on the Statement of Operations.

A 2.00% redemption fee may be imposed on shares of the Funds held for three months or less. Effective with purchases on and after May 15, 2007, a 2% redemption fee may be imposed on shares held for 90 days or less. This fee is paid to the Funds rather than Janus Capital, and is designed to deter excessive short-term trading and to offset the brokerage commissions, market impact, and other costs associated with changes in the Funds' asset levels and cash flow due to short-term money movements in and out of the Funds. The redemption fee is accounted for as an addition to Paid-in Capital. Total redemption fees received by Janus Global Opportunities Fund, Janus Global Research Fund, Janus Overseas Fund and Janus Worldwide Fund were $5,972, $7,123, $1,307,897 and $104,704, respectively, for the six-month period ended April 30, 2007.

For the six-month period ended April 30, 2007, Janus Capital assumed $18,145 of legal, consulting and Trustee costs and fees incurred by the funds in Janus Investment Fund, Janus Aspen Series and Janus Adviser Series (the "Portfolios") in connection with the regulatory and civil litigation matters discussed in Note 6. These non-recurring costs were allocated to all Portfolios, based on the Portfolios' respective net assets as of July 31, 2004. No fees were allocated to Janus Global Research Fund, Janus Triton Fund and the Janus Smart Portfolios as the funds commenced operations after July 31, 2004. Additionally, all future non-recurring costs will be allocated to all Portfolios based upon the Portfolios' respective net assets on July 31, 2004. These non-recurring costs and costs assumed by Janus Capital are shown on the Statement of Operations.

During the fiscal year ended October 31, 2006, Janus Capital assumed tax expenses incurred by Janus Global Opportunities Fund, Janus Overseas Fund and Janus Worldwide Fund in the amount of $23,452, $109,415 and $584,700, respectively, payable to the Internal Revenue Service arising from the overstatements of the foreign taxes paid and the resulting overstatement of reportable foreign tax credits during the 2003 and/or 2004 taxable years. In addition, Janus Capital assumed $68,838 of the interest owed to the Internal Revenue Service.

Effective January 1, 2006, the Board of Trustees adopted a deferred compensation plan (the "Plan") for independent

46 Janus International & Global Funds April 30, 2007

Trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from the Funds. All deferred fees are credited to an account established in the name of the Trustees. The amounts credited to the account then increase or decrease, as the case may be, in accordance with the performance of one or more of the Janus funds that are selected by the Trustees. The account balance continues to fluctuate in accordance with the performance of the selected fund or funds until final payment of all amounts credited to the account. Trustees are allowed to change their designation of mutual funds from time to time. Amounts will be deferred until distributed in accordance with the Plan. No deferred fees were paid to any Trustee under the Plan during the six-month period ended April 30, 2007.

During the six-month period ended April 30, 2007, Janus Services reimbursed the following Fund as a result of dilutions caused by incorrectly processed shareholder activity as indicated in the table below.

6. PENDING LEGAL MATTERS

In addition to the lawsuits described above, the Auditor of the State of West Virginia ("Auditor"), in his capacity as securities commissioner, has initiated administrative proceedings against

Janus International & Global Funds April 30, 2007 49

Notes to Financial Statements (unaudited) (continued)

many of the defendants in the market timing cases (including JCGI and Janus Capital) and, as a part of its relief, is seeking disgorgement and other monetary relief based on similar market timing allegations (In the Matter of Janus Capital Group Inc. et al., Before the Securities Commissioner, State of West Virginia, Summary Order No. 05-1320). The respondents in these proceedings collectively sought a Writ of Prohibition in state court, which was denied. Their subsequent Petition for Appeal was also denied. Consequently, in September 2006, JCGI and Janus Capital filed their answer to the Auditor's summary order instituting proceedings and requested a hearing. A hearing is currently scheduled for June 28, 2007. JCGI and Janus Capital, as well as other similarly situated defendants, continue to challenge the statutory authority of the Auditor to bring such an action.

In addition to the "market timing" actions described above, Janus Capital was a defendant in a consolidated lawsuit in the U.S. District Court for the District of Colorado challenging the investment advisory fees charged by Janus Capital to certain Janus funds (Walter Sins, et al. v. Janus Capital Management LLC, U.S. District Court, District of Colorado, Case No. 04-CV-01647-WDM-MEH; Michael Fleisher, et al. v. Janus Capital Management, LLC, 04-CV-02395-MSK-CBS). The action was filed in 2004 by fund investors asserting breach of fiduciary duty under Section 36(b) of the 1940 Act. The plaintiffs sought declaratory and injunctive relief and an unspecified amount of damages. In April 2007, the parties in the litigation jointly filed a Stipulation Regarding Dismissal of Claims With Prejudice ("Stipulation of Dismissal"), and on May 2, 2007, the Colorado District Court approved the Stipulation of Dismissal and dismissed the case.

Nature, Extent and Quality of Services

The Trustees reviewed the nature, extent and quality of the services provided by Janus Capital the subadvisers to the Funds, taking into account the investment objective and strategy of each Fund and the knowledge the Trustees gained from their regular meetings with management on at least a quarterly basis and their ongoing review of information related to the Funds. In addition, the Trustees reviewed the resources and key personnel of Janus Capital and each subadviser, especially those who provide investment management services to the Funds. The Trustees also considered other services provided to the Funds by Janus Capital or the subadvisers, such as managing the execution of portfolio transactions and the selection of broker-dealers for those transactions, serving as the Funds' administrator, monitoring adherence to the Funds' investment restrictions, producing shareholder reports, providing support services for the Trustees and Trustee committees, communicating with shareholders and overseeing the activities of other service providers, including monitoring compliance with various policies and procedures of the Funds and with applicable securities laws and regulations.

The Trustees concluded that: the nature, extent and quality of the services provided by Janus Capital or the subadviser to each Fund were appropriate and consistent with the terms of the respective advisory and subadvisory agreements; that, taking into account steps taken to address a small portion of the Funds whose performance lagged that of the median of their peers for certain periods, the quality of those services had been consistent with or superior to quality norms in the industry; and that the Funds were likely to benefit from the continued provision of those services. They also concluded that Janus Capital and each subadviser had sufficient personnel, with the appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract and retain well-qualified personnel.

Performance of the Funds

The Trustees considered the performance results of each Fund over various time periods. They reviewed information

Janus International & Global Funds April 30, 2007 51

Additional Information (unaudited) (continued)

comparing each Fund's performance with the performance of comparable funds and peer groups identified by Lipper Inc., an independent provider of investment company data, and with the Fund's benchmark index. They concluded that the performance of most Funds was good to very good under current market conditions. Although the performance of some Funds lagged that of the median of their peers for certain periods, the Trustees also concluded that Janus Capital had taken appropriate steps to address those instances of under-performance and that the more recent performance of most of those Funds had been improving.

Costs of Services Provided

Economies of Scale

52 Janus International & Global Funds April 30, 2007

Capital, Janus Capital is subsidizing the Funds because they have not reached adequate scale. Moreover, as the assets of many of the Funds declined in the past few years, these Funds benefited from having advisory fee rates that remained constant rather than increasing as assets declined. In addition, performance fee structures have been implemented for several Funds that will cause the effective rate of advisory fees payable by such a Fund to vary depending on the investment performance of the Fund relative to its benchmark index over the measurement period; and a few Funds have fee schedules with breakpoints and reduced fee rates above certain asset levels. The Trustees also noted that the Funds share directly in economies of scale through lower charges of third-party service providers based on the combined scale of all of the Funds. Based on all of the information they reviewed, the Trustees concluded that the current fee structure of each Fund was reasonable and that the current rates of fees do reflect a sharing between Janus Capital and the Fund of economies of scale at the current asset level of the Fund.

This statement is often referred to as the "balance sheet." It lists the assets and liabilities of the Funds on the last day of the reporting period.

4. STATEMENT OF OPERATIONS

This statement details the Funds' income, expenses, gains and losses on securities and currency transactions, and appreciation or depreciation of current Fund holdings.

The first section in this statement, entitled "Investment Income," reports the dividends earned from stocks and interest earned from interest-bearing securities in the Funds.

5. STATEMENT OF CHANGES IN NET ASSETS

The reinvestment of dividends is included under "Capital Share Transactions." "Capital Shares" refers to the money investors contribute to the Funds through purchases or withdraw via redemptions. The "Redemption Fees" refers to the fee paid to the Funds for shares held for three months or less by a shareholder. The Funds' net assets will increase and decrease in value as investors purchase and redeem shares from the Funds.

6. FINANCIAL HIGHLIGHTS

The next line reflects the average annual total return reported the last day of the period.

The ratio figure of net investment income/(loss) summarizes the income earned less expenses, divided by the average net assets of a Fund during the reporting period. Don't confuse this ratio with a Fund's yield. The net investment income ratio is not a true measure of a Fund's yield because it doesn't take into account the dividends distributed to the Fund's investors.

The next ratio is the portfolio turnover rate, which measures the buying and selling activity in a Fund. Portfolio turnover is affected by market conditions, changes in the asset size of a Fund, the nature of the Fund's investments and the investment style of the portfolio manager. A 100% rate implies that an amount equal to the value of the entire portfolio is turned over in a year; a 50% rate means that an amount equal to the value of half the portfolio is traded in a year; and a 200% rate means that an amount equal to the value of the portfolio is traded every six months.

Useful Information About Your Fund Report

Management Commentaries

Fund Expenses

We believe it's important for our shareholders to have a clear understanding of Fund expenses and the impact they have on investment return.

Example

Actual Expenses

The first line of the table in each example provides information about actual account values and actual expenses. You may use the information in this line, 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 first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during the period.

Hypothetical Example for Comparison Purposes

The second line of the table in each example provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's 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 Fund 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 funds.

Janus Capital Management LLC ("Janus Capital") has contractually agreed to waive each Bond Fund's total operating expenses, excluding brokerage commissions, interest, taxes and extraordinary expenses, to certain limits until at least March 1, 2008. Janus Capital has agreed to waive one-half of its advisory fee for each Money Market Fund. Such waiver is voluntary and could change or be terminated at any time at the discretion of Janus Capital. Expenses in the examples reflect application of these waivers. Had the waivers not been in effect, your expenses would have been higher. More information regarding the waivers is available in the Funds' prospectuses.

Fund Snapshot

This bond fund invests primarily in federally tax-exempt municipal bonds of any maturity.

Economic Update

Longer term interest rates remained range-bound in the period with the 10-year Treasury falling to a low of nearly 4.40% in early December and backing up to a high of almost 4.90% by late January. Equity markets delivered healthy gains during the period amid continued evidence of strong U.S. economic growth with modest inflation. After a brief period of market volatility in late February and early March, markets rebounded quickly on hopes of monetary easing by the Federal Reserve (Fed).

The Fed left its target interest rate unchanged during the period, taking a more neutral stance in late March by removing its reference to "additional firming" from its monetary policy statement. Though the markets took this to mean a greater potential for a rate cut, the subtle change in the language provided the Fed with some flexibility to adjust monetary policy in either direction. Nevertheless, Fed Chairman Ben Bernanke reiterated the committee's concern over inflation's still elevated level and the Fed's view that although the risks of slower economic growth have risen, the potential for higher inflation remains the greater risk.

Generally, the pace of U.S. economic growth began slowing during the last quarter of 2006, but remained in modest territory. The weak housing market, a slowdown in manufacturing activity and corporate spending, coupled with other pressures facing the consumer are serving to bring into question the economy's ability to maintain its upward momentum. On the other hand, the economy remains fundamentally solid as job growth continued to hold steady, which could serve to prolong the current expansion.

Performance Update

In managing the Fund, my objective is to provide investors with a high level of federally tax-exempt income consistent with the preservation of capital. Depending on my market outlook, I may extend the duration of the Fund's holdings to pursue higher yields and capital appreciation should yields fall. Through much of the recent period, I chose to extend the Fund's duration due to my belief that moderate economic growth might ultimately favor the bond market, particularly at the longer-end of the maturity spectrum. Unfortunately, in a period where yields generally rose, the Fund's longer duration proved detrimental to overall performance, but the additional yield generated from longer-term securities helped to offset the negative impact. This longer duration positioning strategy benefited shareholders later in the period as yields declined below January highs.

Over the course of the six months, I continued to take advantage of robust new issuance within the municipal market, which afforded the opportunity to use rigorous bottom-up credit research and security selection to add value through my allocation to high-yield municipal investments.

The two largest detractors from performance were University of Kansas Hospital Authority Health Facilities Revenue and Cumberland County, Pennsylvania Municipal Authority Revenue due to widening spreads of securities in the investment grade healthcare sector. This sector has experienced pricing pressure due to heavy issuance. The two best performing bonds were Norfolk, Virginia Economic Development Authority and Harrisburg, Pennsylvania Authority Revenue. These two securities are both non-rated high-yield municipals. Spreads have continued to tighten in the high-yield market as investors continue to search for yield and there has been a dearth of high-yield issuance.

Outlook

Looking ahead, I will continue to carefully monitor developments affecting the tax-exempt market and the economy as a whole. It will be most important to watch the Fed balance its dual mandate of sustainable growth and price stability. Continued issuance in the municipal market should present opportunity for individual security selection in both the investment grade and high-yield municipal markets.

Janus Flexible Bond Fund (unaudited)

Ticker: JAFIX

Performance Overview

For the six-month period ended April 30, 2007, Janus Flexible Bond Fund returned 2.79%, modestly outperforming its benchmark, the Lehman Brothers Aggregate Bond Index, which returned 2.64%.

Fund Snapshot

This bond fund continually adjusts its allocations among different types of bond investments in an attempt to take advantage of ever-changing market conditions.

Economic Update

Throughout the period, longer term interest rates stayed within the range we expected. The 10-year Treasury fell to a low of nearly 4.40% in early December and increased to a high of almost 4.90% by late January. Equity markets delivered healthy gains during the period amid continued evidence of modestly slowing U.S. economic growth with modest inflation. After a brief period of market volatility in late February and early March, markets rebounded quickly on hopes of monetary easing by the Federal Reserve (Fed).

The Fed left its target interest rate unchanged during the period, taking a more neutral stance in late March by removing its reference to "additional firming" from its monetary policy statement. Although the markets took this to indicate a greater potential for a rate cut, the subtle change in the language simply provided the Fed with some flexibility to adjust monetary policy in either direction. Nevertheless, Fed Chairman Ben Bernanke reiterated the committee's concern over inflation's still elevated level and the Fed's view that although the risks of slower economic growth rose, the potential for higher inflation remains the greater risk.

Generally, the pace of U.S. economic growth slowed during the last quarter of 2006, but remained in modest territory. The weak housing market, a slowdown in manufacturing activity and corporate spending, coupled with other consumer pressures brought into question the economy's ability to maintain its upward momentum. On the other hand, the economy remained fundamentally solid as job growth continued to hold steady, which could serve to prolong the current expansion.

Corporate Bonds and Mortgage-Backed Securities Aided Performance

Relative performance during the period was supported by the Fund's exposure to corporate bonds. An example was Xerox, which received a credit upgrade from Moody's Investor Service in recognition of its stable profitability and healthy cash flow growth, as well as the expectation that the company may reduce leverage.

Additionally, the Fund benefited from its above-benchmark weighting in higher-yield corporate bonds, which performed well for the period overall. In particular, I capitalized on my decision to invest in bonds issued by hospital management firm, HCA, following its November management-led leveraged buyout. The bonds of this asset-rich, cash flow generative business subsequently rallied, benefiting performance. Finally, results were supported by my stake in mortgage-backed securities, which generally perform well in an environment of low-yield volatility.

Duration Strategy Provided Mixed Results

The Fund's duration positioning provided mixed results. On a positive note, the out-of-benchmark investment in short-term bank loans and high-yield bonds served to reduce duration, while yields generally rose in the period. On the other hand, I used longer-term treasury securities in an effort to offset this shortening impact, which proved detrimental in the rising yield environment.

Additionally, while the Fund avoided major credit problems, I was disappointed by the performance of the TXU bonds. The Texas-based energy utility faced concerns that a recent buyout could increase debt and hurt the interests of current bondholders.

Outlook

Looking ahead, the team will continue to carefully monitor developments affecting the fixed-income markets. In this environment, Treasury yields are expected to remain range-bound, while investors await more clarity on the strength of the economy, the risks of inflation and the likely response of the Fed policymakers. The team will continue to utilize a flexible investment strategy in an effort to mitigate downside risk, while seeking opportunities to augment total return by investing in spread instruments such as mortgage-backed securities and corporate bonds.

In closing, I recently announced that after 21 years with Janus, I will retire from my portfolio manager responsibilities for Janus Flexible Bond Fund, effective May 15, 2007. Gibson Smith, Co-Chief Investment Officer of Janus Capital,

(unaudited)

co-portfolio manager of Janus Balanced Fund and portfolio manager of Janus High-Yield Fund; and Darrell Watters, a 14-year veteran of the fixed-income team with 21 years of professional investment experience, will succeed me and will serve as co-portfolio managers of the Fund.

After working closely with Gibson and Darrell over the last several years, I have high confidence in their ability to successfully manage the Fund. They will work closely to manage the Fund with the support of the strong fixed-income analyst team that we have built over the years. I believe that Gibson's and Darrell's combined experience and knowledge about the markets make them ideally suited to take over the Fund.

It has been an honor to have worked on your behalf. Thank you for your support over the years.

The Fund's total operating expenses did not exceed the expense limit so no waivers were in effect for the most recent period presented.

High-yield/high-risk bonds involve a greater risk of default and price volatility than U.S. Government and other high-quality bonds. High-yield/high-risk bonds can experience sudden and sharp price swings which will affect net asset value.

July 9, 1987 is the date used to calculate the since-inception Lipper ranking, which is slightly different from when the Fund began operations since Lipper provides fund rankings as of the last day of the month or the first Thursday after fund inception.

There is no assurance that the investment process will consistently lead to successful investing.

The Fund will invest at least 80% of its net assets in the type of securities described by its name.

Effective May 15, 2007, Gibson Smith and Darrell Watters will become Co-Portfolio Managers of Janus Flexible Bond Fund.

Janus High-Yield Fund (unaudited)

Ticker: JAHYX

Performance Overview

For the six-month period ended April 30, 2007, Janus High-Yield Fund posted a gain of 6.53%, compared to a 6.88% increase of its benchmark, the Lehman Brothers High-Yield Bond Index.

Fund Snapshot

This bond fund strives to provide exposure to the best income and total return opportunities in the high-yield market.

Economic Update

Throughout the period, longer term interest rates stayed within the range we expected. The 10-year Treasury fell to a low of nearly 4.40% in early December and increased to a high of almost 4.90% by late January. Equity markets delivered healthy gains during the period amid continued evidence of strong U.S. economic growth with modest inflation. After a brief period of market volatility in late February and early March, markets rebounded quickly on hopes of monetary easing by the Federal Reserve (Fed).

The Fed left its target interest rate unchanged during the period, taking a more neutral stance in late March by removing its reference to "additional firming" from its monetary policy statement. Although the markets took this to indicate a greater potential for a rate cut, the subtle change in the language simply provided the Fed with some flexibility to adjust monetary policy in either direction. Nevertheless, Fed Chairman Ben Bernanke reiterated the committee's concern over inflation's still elevated level and the Fed's view that although the risks of slower economic growth rose, the potential for higher inflation remains the greater risk.

Generally, the pace of U.S. economic growth slowed during the last quarter of 2006, but remained in modest territory. The weak housing market, a slowdown in manufacturing activity and corporate spending, coupled with other pressures facing the consumer brought into question the economy's ability to maintain its upward momentum. On the other hand, the economy remained fundamentally solid as job growth continued to hold steady, which could serve to prolong the current expansion.

Homebuilder Investments Weighed on Results

While the Fund's relative performance benefited from a lack of direct exposure to troubled subprime lenders, the pressures in this market cast a shadow over the fixed-income investments in the homebuilder market. Specifically, homebuilders K. Hovnanian Enterprises and Beazer Homes USA faced concerns over an existing oversupply of new homes for sale, as well as from the possibility that rising foreclosures might flood the market with a supply of existing properties.

Additionally, among our utilities holdings, positions in energy utility TXU experienced downward pressure as concerns that the recent buyout by a private investment firm would add to the company's existing debt load, and could negatively impact credit quality.

Healthcare, Automotive and Gaming Bonds Aided Performance

Performance benefited from exposure to select healthcare names researched by Jason Groom our fixed-income healthcare analyst. These included our investments in HCA, a hospital management company, and HEALTHSOUTH, a provider of surgical, rehabilitation and medical-imaging services. I purchased our HCA bonds following the company's management-led leveraged buyout. The bonds of this asset-heavy, free cash flow generative business subsequently rallied, supporting performance. The position in HEALTHSOUTH, meanwhile, benefited from speculation that the company might use cash generated by the recent sale of non-core assets as tender for some of its outstanding debt.

Results were further supported by exposure to the automotive and gaming sectors. In the automotive sector, Dan Porter's overweight recommendation on Goodyear Tire & Rubber benefited from encouraging news about replacement tire pricing and resolution of labor disputes, as well as from its ongoing efforts to deleverage its balance sheet by paying down debt. Turning to the gaming industry, another Jason Groom pick, Trump Entertainment Resorts bonds gained ground on market anticipation that the casino and hotel company might be sold.

Outlook

Looking ahead, I plan to continue to carefully monitor developments affecting the macro economy and the fixed-income markets. A more resilient than expected economy could prove positive for the high-yield market, while resurgent inflation pressures putting upward pressure on interest rates, could lead to a repricing of risk in the credit markets. The upsurge in activity by private equity firms taking companies

private demands attention. We are paying very close attention to valuations in the credit markets with a keen focus on the upside/downside relationship on the securities that enter the portfolios. In this environment, with my very strong fixed income team, we will continue to look across the entire credit spectrum for what we believe are the best opportunities in the credit markets.

Thank you for your interest in Janus High-Yield Fund.

Janus Short-Term Bond Fund (unaudited)

Ticker: JASBX

Performance Overview

For the six-month period ended April 30, 2007, Janus Short-Term Bond Fund returned 2.54%, slightly outperforming a 2.42% increase of its benchmark, the Lehman Brothers Government/Credit 1-3 Year Index.

Fund Snapshot

This conservative bond fund looks for investments that can provide a modest return while minimizing risk.

Economic Update

The Fed left its target interest rate unchanged during the period, taking a more neutral stance in late March by removing its reference to "additional firming" from its monetary policy statement. Though the markets took this to mean a greater potential for a rate cut, the subtle change in the language provided the Fed with some flexibility to adjust monetary policy in either direction. Nevertheless, Fed Chairman Ben Bernanke reiterated the committee's concern over inflation's still elevated level and the Fed's view that although the risks of slower economic growth rose, the potential for higher inflation remained the greater risk.

Generally, the pace of U.S. economic growth slowed during the last quarter of 2006, but remained in modest territory. The weak housing market, a slowdown in manufacturing activity and corporate spending, coupled with other pressures facing the consumer served to bring into question the economy's ability to maintain its upward momentum. On the other hand, the economy remained fundamentally solid as job growth continued to hold steady, which could serve to prolong the current expansion.

Short-Term Bank Loans Aided Performance

On a positive note, the Fund benefited from its out-of-benchmark allocation to floating rate bank loans, as well as from its investment in copper mining company Freeport-McMoran Copper & Gold. Freeport completed its acquisition of Phelps Dodge in March creating the world's largest copper company. Subsequent to the acquisition, the company launched a new public stock offering and earmarked a portion of the proceeds for repayment of debt incurred in the buyout. This announcement of the company's intention to de-leverage its balance sheet benefited the outstanding debt issues.

Among corporate credit holdings, my investment in energy utility TXU Energy contributed to the Fund's performance. However, the company recently announced a leveraged buyout that we think could result in higher balance sheet leverage, to the detriment of its outstanding debt. We believe the holdings in the Short-Term Bond Fund would be required to be tendered to facilitate the private transaction.

Focus on Treasury Holdings Hindered Results

During a period in which lower quality, high-yielding bonds tended to outperform the broader fixed-income category, the Fund's more conservative positions hindered performance. In particular, the Fund suffered from its overweight to U.S. Treasury bonds, which struggled as yields were range-bound and spread-based products (products designed to generate income based on the difference between investment returns on the supporting assets and the returns credited to customers) outperformed. Despite these results, I stand by my efforts to preserve capital in what I felt was an uncertain investment climate.

Outlook

Looking ahead, I expect Treasury yields to remain range-bound, while investors await more clarity on the strength of the economy, the risks of inflation and the likely response of Federal Reserve policymakers. In this environment, I will continue to carefully monitor economic developments, while relying on disciplined, bottom-up fundamental research to uncover opportunities for a moderate out-of-benchmark allocation to floating rate bank loans.

In closing, I recently announced that, in addition to my responsibilities as co-chief investment officer for the firm and portfolio manager of the Janus high yield strategies and co-manager of the Janus balanced strategies, I will also co-manage the flexible bond strategies. This means I will now entrust the Janus Short-Term Bond Fund to two of my very capable colleagues.

I am pleased to announce that Darrell Watters, a 14-year veteran of the fixed income team with 21 years of professional investment experience, and Jason Groom, a seasoned fixed income professional with 13 years of investment experience, will succeed me and will serve as co-managers of the Fund.

I have worked closely with Darrell and Jason and I am confident in their ability to successfully manage the Fund. I believe that their combined experience and market knowledge should make them ideally suited to take over the Fund. In addition, they will work closely in managing the Fund with the strong fixed income team that we have built over the years. You will find that both Darrell and Jason embrace the same disciplined principles that I hold dear to the entire fixed income group, with a cornerstone of in-depth fundamental research and a focus on delivering solid risk adjusted returns.

It has been a privilege to have worked on your behalf. Thank you for all your support over the years.

An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Funds seek to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Funds.

Janus Capital Management LLC has agreed to waive one-half of its advisory fee. Such waiver is voluntary and could change or be terminated at any time at the discretion of Janus Capital. Total returns shown include fee waivers, if any, and without such waivers, the Fund's yields and total returns would have been lower.

Each Fund's expense ratios were determined based on average assets as of the fiscal year ended October 31, 2006. Detailed information is available in the prospectus. All expenses are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

Total return includes reinvestment of dividends and capital gains.

The yield more closely reflects the current earnings of each Money Market Fund than the total return.

The Funds will invest at least 80% of their net assets in the type of securities described by their name.

Income may be subject to state or local taxes and to a limited extent certain federal tax.

Effective April 16, 2007, Craig Jacobson became Co-Portfolio Manager of Janus Money Market Fund.

The interest rate on floating rate notes is based on an index or market interest rates and is subject to change. Rates in the security description are as of April 30, 2007.

Money market funds may hold securities with stated maturities of greater than 397 days when those securities have features that allow a fund to "put" back the security to the issuer or to a third party within 397 days of acquisition. The maturity dates shown in the security descriptions are the stated maturity dates.

Repurchase agreements held by a Fund are fully collateralized, and such collateral is in the possession of the Fund's custodian or subcustodian. The collateral is evaluated daily to ensure its market value equals or exceeds the current market value of the repurchase agreements, including accrued interest. In the event of default on the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. In the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral or proceeds may be subject to legal proceedings.

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Janus Federal Tax-Exempt Fund, Janus Flexible Bond Fund, Janus High-Yield Fund and Janus Short-Term Bond Fund (collectively the "Bond Funds") and Janus Money Market Fund, Janus Government Money Market Fund and Janus Tax-Exempt Money Market Fund (collectively the "Money Market Funds") are series funds. The Bond Funds and the Money Market Funds (collectively the "Funds" and individually a "Fund") are part of Janus Investment Fund (the "Trust"), which was organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the "1940 Act") as an open-end management investment company. The Trust has thirty funds. The Bond Funds invest primarily in income-producing securities, and the Money Market Funds invest in high-quality money market instruments. Each of the Bond Funds in this report is classified as diversified as defined in the 1940 Act. The Funds are no-load investments.

Effective February 23, 2007, the Institutional Shares and Service Shares of Janus Money Market Fund and Janus Government Money Market Fund were reorganized into corresponding classes of Janus Institutional Money Market Fund and Janus Institutional Government Money Market Fund, respectively. The Institutional Shares and Service Shares of Janus Tax-Exempt Money Market Fund were liquidated from the Trust. Accordingly, Institutional Shares and Service Shares of Janus Money Market Fund, Janus Government Money Market Fund and Janus Tax-Exempt Money Market Fund are no longer offered for sale.

Investment Valuation

Securities are valued at the last sales price or the official closing price for securities traded on a principal securities exchange (U.S. or foreign) and on the NASDAQ National Market. Securities traded on over-the-counter markets and listed securities for which no sales are reported are valued at the latest bid price (or yield equivalent thereof) obtained from one or more dealers transacting in a market for such securities or by a pricing service approved by the Funds' Trustees. Short-term securities with maturities of 60 days or less may be valued at amortized cost, which approximates market value. Investments held by the Money Market Funds are valued at the amortized cost method of valuation permitted in accordance with Rule 2a-7 under the 1940 Act and certain conditions therein. Under the amortized cost method, which does not take into account unrealized capital gains or losses, an instrument is initially valued at its cost and thereafter assumes a constant accretion/amortization to maturity of any discount or premium. Debt securities with a remaining maturity of greater than 60 days are valued in accordance with the evaluated bid price supplied by the pricing service. The evaluated bid price supplied by the pricing service is an evaluation that reflects such factors as security prices, yields, maturities and ratings. Foreign securities and currencies are converted to U.S. dollars using the applicable exchange rate in effect as of the daily close of the New York Stock Exchange ("NYSE"). When market quotations are not readily available or deemed unreliable, or events or circumstances that may affect the value of portfolio securities held by the Funds are identified between the closing of their principal markets and the time the net asset value ("NAV") is determined, securities may be valued at fair value as determined in good faith under procedures established by and under the supervision of the Funds' Trustees. The Funds may use a systematic fair valuation model provided by an independent third party to value international equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the NYSE.

Investment Transactions and Investment Income

Expenses

Each Bond Fund bears expenses incurred specifically on its behalf as well as a portion of general expenses. Each class of shares of each Money Market Fund bears expenses incurred specifically on its behalf and, in addition, each class bears a portion of general expenses, which may be based upon relative net assets of each class. Expenses are allocated daily to each class of shares based upon the ratio of new assets represented by each class as a percentage of total net assets. Expenses directly attributable to a specific class of shares are charged against the operations of such class.

Securities Lending

Under procedures adopted by the Trustees, the Funds may lend securities to qualified parties (typically brokers or other financial institutions) who need to borrow securities in order to complete certain transactions such as covering short sales, avoiding failures to deliver securities or completing arbitrage activities. The Funds may seek to earn additional income through securities lending. There is the risk of delay in recovering a loaned security or the risk of loss in collateral rights if the borrower fails financially. In addition, Janus Capital makes efforts to balance the benefits and risks from granting such loans.

As of April 30, 2007, the following Funds had on loan securities valued as indicated:

Fund	Value at April 30, 2007
Bond
Janus Flexible Bond Fund	$	119,997,565
Janus High-Yield Fund		113,833,835
Janus Short-Term Bond Fund		43,509,242

As of April 30, 2007, the following Funds received cash collateral for securities lending activity as indicated:

Fund	Cash Collateral at April 30, 2007
Bond
Janus Flexible Bond Fund	$	122,427,015
Janus High-Yield Fund		116,209,915
Janus Short-Term Bond Fund		44,397,740

As of April 30, 2007, all cash collateral received by the Funds was invested in the State Street Navigator Securities Lending Prime Portfolio.

During the six-month period ended April 30, 2007, there were no securities lending arrangements for Janus Federal Tax-Exempt Fund or the Money Market Funds.

Interfund Lending

Short Sales

Forward Currency Transactions

The Bond Funds may enter into forward currency contracts in order to reduce their exposure to changes in foreign currency exchange rates on their foreign portfolio holdings and to lock in the U.S. dollar cost of firm purchase and sale commitments for securities denominated in or exposed to foreign currencies. A forward currency exchange contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated

62 Janus Bond & Money Market Funds April 30, 2007

rate. The gain or loss arising from the difference between the U.S. dollar cost of the original contract and the value of the foreign currency in U.S. dollars upon closing a contract is included in "Net realized gain/(loss) from foreign currency transactions" on the Statement of Operations (if applicable).

Forward currency contracts held by the Bond Funds are fully collateralized by other securities, which are denoted in the accompanying Schedule of Investments (if applicable). The collateral is evaluated daily to ensure its market value equals or exceeds the current market value of the corresponding forward currency contracts.

As of April 30, 2007, Janus Flexible Bond Fund was invested in forward currency transactions.

Futures Contracts

The Bond Funds may enter into futures contracts. The Bond Funds intend to use such derivative instruments to hedge or protect from adverse movements in securities prices, currency rates or interest rates. The use of futures contracts may involve risks such as the possibility of illiquid markets or imperfect correlation between the value of the contracts and the underlying securities, or that the counterparty will fail to perform its obligations.

Mortgage Dollar Rolls

The Bond Funds may enter into "mortgage dollar rolls." In a "mortgage dollar roll" transaction, the Fund sells a mortgage-related security (such as a Government National Mortgage Association ("GNMA") security) to a dealer and simultaneously agrees to repurchase a similar security (but not the same security) in the future at a pre-determined price. The Fund will not be entitled to receive interest and principal payments while the dealer holds the security. The difference between the sale price and the future purchase price is recorded as an adjustment to investment income.

The Fund's obligations under a dollar roll agreement must be covered by cash, U.S. Government securities or other liquid high grade debt obligations equal in value to the securities subject to repurchase by the Fund, maintained in a segregated account. To the extent that the Fund collateralizes its obligations under a dollar roll agreement, the asset coverage requirements of the 1940 Act will not apply to such transactions. Furthermore, under certain circumstances, an underlying mortgage-backed security that is part of a dollar roll transaction may be considered illiquid.

Successful use of mortgage dollar rolls depends on the Fund's ability to predict interest rates and mortgage payments. Dollar roll transactions involve the risk that the market value of the securities the Fund is required to purchase may decline below the agreed upon repurchase price.

The Bond Funds were not invested in dollar rolls during the six-month period ended April 30, 2007.

Bank Loans

The Bond Funds may invest in bank loans, which include institutionally traded floating rate securities generally acquired as an assignment or participation interest in loans originated by a bank or financial institution (the "Lender") that acts as agent for all holders. The agent administers the terms of the loan, as specified in the loan agreement. When investing in a loan participation, the Fund has the right to receive payments of principal, interest and any fees to which it is entitled only from the Lender selling the loan agreement and only upon receipt by the Lender of payments from the borrower. The Fund generally has no right to enforce compliance with the terms of the loan agreement with the borrower. Assignments and participations involve credit, interest rate, and liquidity risk. Interest rates on floating rate securities adjust with general interest rate changes and/or issuer credit quality. The interest rates paid on a floating rate security in which the Fund invests generally are readjusted every 45-60 days, on average, to an increment over a designated benchmark rate, such as the one-month, three-month, six-month, or one-year London Interbank Offered Rate ("LIBOR'').

The average monthly value of borrowings outstanding under bank loan arrangements during the six-month period ended April 30, 2007 are noted in the table below.

Fund	Average Monthly Value		Rates
Bond
Janus Flexible Bond Fund	$	20,193,318	2.10%-8.60988%
Janus High-Yield Fund		26,726,401	0.500%-12.36%
Janus Short-Term Bond Fund		15,785,004	7.06250%-9.50%

Notes to Financial Statements (unaudited) (continued)

Securities Traded on a To-Be-Announced Basis

The Bond Funds may trade securities on a to-be-announced ("TBA") basis. In a TBA transaction, the Fund commits to purchasing or selling securities for which specific information is not yet known at the time of the trade, particularly the face amount and maturity date in GNMA, Federal National Mortgage Association ("FNMA") and/or Federal Home Loan Mortgage Corporation ("FHLMC") transactions. Securities purchased on a TBA basis are not settled until they are delivered to the Fund, normally 15 to 45 days later. Beginning on the date the Fund enters into a TBA transaction, cash, U.S. Government securities or other liquid high-grade debt obligations are segregated in an amount equal in value to the purchase price of the TBA security. These transactions are subject to market fluctuations and their current value is determined in the same manner as for other securities.

At April 30, 2007, the Bond Funds were not invested in TBA securities.

When-issued Securities

The Funds may purchase or sell securities on a when-issued or forward commitment basis. The price of the underlying securities and date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Losses may arise due to changes in the market value of the securities or from the inability of counterparties to meet the terms of the contract. In connection with such purchases, the Fund may hold liquid assets as collateral with the Fund's custodian sufficient to cover the purchase price. As of April 30, 2007, the Funds were not invested in when-issued securities.

Foreign Currency Translation

Equity-Linked Structured Notes

The Funds may invest in equity-linked structured notes. Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or nonregistered form. An investment in equity-linked structured notes creates exposure to the credit risk of the issuing financial institution, as well as to the market risk of the underlying securities. There is no guaranteed return of principal with these securities and the appreciation potential of these securities may be limited by a maximum payment or call right. In certain cases, equity-linked structured notes may be more volatile and less liquid than less complex securities or other types of fixed-income securities. Such securities may exhibit price behavior that does not correlate with other fixed-income securities. As of April 30, 2007, the Funds were not invested in equity-linked structured notes.

Initial Public Offerings

The Bond Funds may invest in initial public offerings ("IPOs"). IPOs and other investment techniques may have a magnified performance impact on a fund with a small asset base. A Fund may not experience similar performance as its assets grow.

Additional Investment Risk

Janus High-Yield Fund, Janus Flexible Bond Fund and Janus Short-Term Bond Fund may be invested in lower-rated debt securities that have a higher risk of default or loss of value since these securities may be sensitive to economic changes, political changes or adverse developments specific to the issuer.

Restricted Security Transactions

Dividend Distributions

Dividends representing substantially all of the Money Market Funds' net investment income are declared daily and generally distributed monthly. Capital gains, if any, are declared and distributed in December. The majority of dividends and capital gains distributions from a Fund will be automatically reinvested into additional shares of that Fund, based on the discretion of the shareholder.

2. INVESTMENT ADVISORY AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

Each Bond Fund pays a monthly advisory fee to Janus Capital based upon average daily net assets and calculated at the annual rate shown in the table below.

Fund	Average Daily Net Assets of Fund	Management Fee %
Janus Federal Tax-Exempt Fund	First $300 Million Over $300 Million	0.50% 0.45%
Janus Flexible Bond Fund	First $300 Million Over $300 Million	0.58% 0.48%
Janus High-Yield Fund	First $300 Million Over $300 Million	0.65% 0.55%
Janus Short-Term Bond Fund	First $300 Million Over $300 Million	0.64% 0.54%

Until at least March 1, 2008, provided that Janus Capital remains investment adviser to the Bond Funds, Janus Capital has agreed to reimburse the following Funds by the amount, if any, that such Fund's normal operating expenses in any fiscal year, including the investment advisory fee, but excluding brokerage commissions, interest, taxes and extraordinary expenses, exceed the annual rates noted below. If applicable, amounts reimbursed to the Funds by Janus Capital are disclosed as Excess Expense Reimbursement on the Statement of Operations.

Fund	Expense Limit Fee %
Bond
Janus Federal Tax-Exempt Fund		0.55	%
Janus Flexible Bond Fund		0.93	%
Janus High-Yield Fund		0.90	%
Janus Short-Term Bond Fund		0.64	%

Each of the Money Market Funds pays Janus Capital 0.20% of its average daily net assets as an investment advisory fee. However, Janus Capital has agreed to waive one-half of its advisory fee. Such waiver is voluntary and could change or be terminated at any time at the discretion of Janus Capital. In addition, the Money Market Funds pays Janus Capital an administrative services fee. This fee is 0.50%, 0.15%, and 0.40% of average daily net assets. The Money Market Funds pay those expenses not assumed by Janus Capital. The expenses not assumed by Janus Capital include interest and taxes, fees and expenses of Trustees who are not interested persons of Janus Capital, audit fees and expenses, and extraordinary expenses.

A 2.00% redemption fee may be imposed on shares of Janus High-Yield Fund held for three months or less. Effective with purchases on and after May 15, 2007, a 2% redemption fee may be imposed on shares held for 90 days or less. This fee is paid to the Fund rather than Janus Capital, and is designed to deter excessive short-term trading and to offset the brokerage commissions, market impact, and other costs associated with changes in the Fund's asset level and cash flow due to short-term money movements in and out of the Fund. The redemption fee is accounted for as an addition to Paid-in Capital. Total redemption fees received by Janus High-Yield Fund were $61,141 for the six-month period ended April 30, 2007.

Each of the Bond Funds pays Janus Services LLC ("Janus Services"), a wholly owned subsidiary of Janus Capital, an asset-weighted average annual fee based on the proportion of each Bond Fund's total net assets sold directly and the proportion of each Bond Fund's net assets sold through financial intermediaries. The applicable fee rates are 0.16% of net assets on the proportion of assets sold directly and 0.21% on the proportion of assets sold through intermediaries. In addition, Janus Services receives $4.00 per open shareholder account from each Bond Fund for transfer agent services.

During the six-month period ended April 30, 2007, Janus Services reimbursed the following Fund as a result of dilutions

Janus High-Yield Fund	$	6

For the six-month period ended April 30, 2007, Janus Capital assumed $18,145 of legal, consulting and Trustee costs and fees incurred by the funds in Janus Investment Fund, Janus Aspen Series and Janus Adviser Series (the "Portfolios") in connection with the regulatory and civil litigation matters discussed in Note 6. These non-recurring costs were allocated to all Portfolios, based upon the Portfolios' respective net assets as of July 31, 2004. No fees were allocated to Janus Global Research Fund, Janus Triton Fund and the Janus Smart Portfolios as the funds commenced operations after July 31, 2004. Additionally, all future non-recurring costs will be allocated to all Portfolios based upon the Portfolios' respective net assets on July 31, 2004. These non-recurring costs and costs assumed by Janus Capital are shown on the Statement of Operations.

The Bond Funds' expenses may be reduced by expense offsets from an unaffiliated custodian and/or transfer agent. Such offsets are included in Expense and Fee Offsets on the Statement of Operations. The transfer agent fee offsets received during the period reduce Transfer Agent Fees and Expenses. Custodian offsets received reduce Custodian Fees. The Funds could have employed the assets used by the custodian and/or transfer agent to produce income if they had not entered into an expense offset arrangement.

6. PENDING LEGAL MATTERS

A number of civil lawsuits were brought against Janus Capital and certain of its affiliates, the Janus funds, and related entities and individuals based on allegations similar to those announced by the above regulators and were filed in several state and federal jurisdictions. Such lawsuits alleged a variety of theories for recovery including, but not limited to, the federal securities laws, other federal statutes (including ERISA), and various common law doctrines. The Judicial Panel on Multidistrict Litigation transferred these actions to the U.S. District Court for the District of Maryland (the "Court") for coordinated proceedings. On September 29, 2004, five consolidated amended complaints were filed with the Court that generally include: (i) claims by a putative class of investors in certain Janus funds asserting claims on behalf of the investor class (Marini, et al. v. Janus Investment Fund, et al., U.S. District Court, District of Maryland, Case No. 04-CV-00497); (ii) derivative claims by investors in certain Janus funds ostensibly on behalf of such funds (Steinberg et al. v. Janus Capital Management, LLC et al., U.S. District Court, District of Maryland, Case No. 04-CV-00518); (iii) claims on behalf of participants in the Janus 401(k) plan (Wangberger v. Janus Capital Group Inc., 401(k) Advisory Committee, et al., U.S. District Court, District of Maryland, Case No. JFM-05-2711); (iv) claims brought on behalf of shareholders of Janus Capital Group Inc. ("JCGI") on a derivative basis against the Board of Directors of JCGI (Chasen v. Whiston, et al., U.S. District Court, District of Maryland, Case No. 04-MD-00855); and (v) claims by a putative class of shareholders of JCGI asserting claims on behalf of the shareholders (Wiggins, et al. v. Janus Capital Group, Inc., et al., U.S. District Court, District of Maryland, Case No. 04-CV-00818). Each of the five complaints initially named JCGI and/or Janus Capital as a defendant. In addition, the following were also named as defendants in one or more of the actions: Janus Investment Fund ("JIF"), Janus Aspen Series ("JAS"), Janus Adviser Series ("JAD"), Janus Distributors LLC, Enhanced Investment Technologies, LLC ("INTECH"), Bay Isle Financial LLC ("Bay Isle"), Perkins, Wolf, McDonnell and Company, LLC ("Perkins"), the Advisory Committee of the Janus 401(k) plan, and the current or former directors of JCGI.

Fund, the quality of services provided by Janus Capital and any subadviser, the investment performance of the Fund and any expense limitations agreed to by Janus Capital.

Economies of Scale

Other Benefits to Janus Capital

The Trustees also considered benefits that accrue to Janus Capital and its affiliates from their relationships with the Funds. They recognized that two affiliates of Janus Capital separately serve the Funds as transfer agent and distributor, respectively, and that the transfer agent receives compensation directly from the non-money market Funds for services provided. The Trustees also considered Janus Capital's past and proposed use of commissions paid by the Funds on their portfolio brokerage transactions to obtain proprietary research products and services benefiting those Funds and/or other clients of Janus Capital, as well as Janus Capital's prior agreement not to use any Fund's brokerage transactions to obtain third party research products or services. The Trustees concluded that Janus Capital's use of "soft" commission dollars of a Fund to obtain proprietary research products and services was consistent with regulatory requirements and guidelines and was likely to benefit the Funds. The Trustees also concluded that, other than the services provided by Janus Capital and its affiliates pursuant to the agreements and the fees to be paid by each Fund therefor, the Funds and Janus Capital may potentially benefit from their relationship with each other in other ways. They concluded that Janus Capital benefits from the receipt of proprietary research products and services acquired through commissions paid on portfolio transactions of the Funds and that the Funds benefit from Janus Capital's receipt of those products and services as well as research products and services acquired through commissions paid by other clients of Janus Capital. They further concluded that success of any Fund could attract other business to Janus Capital or other Janus funds and that the success of Janus Capital could enhance Janus Capital's ability to serve the Funds.

but not yet paid. Additionally, there may be other assets and liabilities such as unrealized gain or loss on forward currency contracts.

4. STATEMENT OF OPERATIONS

This statement details the Funds' income, expenses, gains and losses on securities and currency transactions, and appreciation or depreciation of current Fund holdings.

The first section in this statement, entitled "Investment Income," reports the dividends earned from stocks and interest earned from interest-bearing securities in the Funds.

The next section reports the expenses and expense offsets incurred by the Funds, including the advisory fee paid to the investment adviser, transfer agent fees and expenses, and printing and postage for mailing statements, financial reports, prospectuses and other expenses. Expense offsets, if any, are also shown.

5. STATEMENT OF CHANGES IN NET ASSETS

The reinvestment of dividends is included under "Capital Share Transactions." "Capital Shares" refers to the money investors contribute to the Funds through purchases or withdraw via redemptions. The "Redemption Fees" refers to the fee paid to certain Funds for shares held for three months or less by a shareholder. The Funds' net assets will increase and decrease in value as investors purchase and redeem shares from the Funds.

6. FINANCIAL HIGHLIGHTS

The next line reflects the average annual total return reported the last day of the period.

Also included are the expense ratios, or the percentage of average net assets that were used to cover operating expenses during the period. Expense ratios vary across the Funds for a number of reasons, including the differences in management fees, the average shareholder account size and the extent of foreign investments, which entail greater transaction costs.

The Funds' expenses may be reduced through expense reduction arrangements. These arrangements may include the use of balance credits or transfer agent fee offsets. The Statement of Operations reflects total expenses before any such offset, the amount of offset and the net expenses. The expense ratios listed in the Financial Highlights reflect total expenses prior to any expense offsets (gross expense ratio) and after the expense offsets (net expense ratio). Both expense ratios reflect expenses after waivers (reimbursements), if applicable.

The ratio of net investment income/(loss) summarizes the income earned less expenses, divided by the average net assets

of a Fund during the reporting period. Don't confuse this ratio with a Fund's yield. The net investment income ratio is not a true measure of a Fund's yield because it doesn't take into account the dividends distributed to the Fund's investors.

about the strength of consumer spending abound, we feel valuations for equities are reasonable by historic standards. In fact, as overall economic growth slows, investors could place an increasing premium on the shares of companies with strong growth prospects.

Regardless of the macroeconomic climate, we remain dedicated to rewarding your confidence in Janus with strong, consistent fund performance.

Useful Information About Your Portfolio Report

Management Commentaries

The Management Commentaries in this report include valuable insight from the Portfolios' manager as well as statistical information to help you understand how your Portfolio's performance and characteristics stack up against those of comparable indices.

Please keep in mind that the opinions expressed by the Portfolios' manager in the Management Commentaries are just that: opinions. They are a reflection of his best judgment at the time this report was compiled, which was April 30, 2007. As the investing environment changes, so could his opinions. These views are unique to the manager and aren't necessarily shared by his fellow employees or by Janus in general.

Fund Expenses

We believe it's important for our shareholders to have a clear understanding of Portfolio expenses and the impact they have on investment return.

The following is important information regarding each Portfolio's Expense Example, which appears in each Portfolio's Management Commentary within this Semiannual Report. Please refer to this information when reviewing the Expense Example for each Portfolio.

Example

As a shareholder of a Portfolio, you incur two types of costs: (1) transaction costs, such as underlying funds' redemption fees (where applicable) (and any related exchange fees) and (2) ongoing costs, including management fees and other Portfolio expenses. The example is intended to help you understand your ongoing costs (in dollars) of investing in a Portfolio and to compare these costs with the ongoing costs of investing in other mutual funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the period from November 1, 2006 to April 30, 2007.

Actual Expenses

Hypothetical Example for Comparison Purposes

The second line of the table in each example provides information about hypothetical account values and hypothetical expenses based on the Portfolio's actual expense ratio and an assumed rate of return of 5% per year before expenses. This is not the Portfolio's 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 Portfolio 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 funds.

Janus Capital Management LLC ("Janus Capital") has contractually agreed to waive each Portfolio's total operating expenses, excluding any expenses of an underlying fund, brokerage commissions, interest, taxes and extraordinary expenses to certain limits until at least March 1, 2008. Expenses in the example reflect the application of this waiver. Had the waiver not been in effect, your expenses would have been higher. More information regarding the waiver is available in the Portfolios' prospectus.

Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as underlying funds' redemption fees (where applicable). These fees are fully described in the prospectus. Therefore, the second line of each table 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 transaction costs were included, your costs would have been higher.

Janus Smart Portfolio – Growth gained 10.95% for the six-month period ending April 30, 2007, compared to the S&P 500^® Index's return of 8.60% for the same period. The Portfolio outpaced its secondary benchmark, the internally calculated, hypothetical Growth Allocation Index, which returned 9.87%. These results were consistent with the Portfolio's objective, which is to provide exposure to both stocks and bonds with a clear emphasis on growth of capital.

Market Review

Equity markets delivered healthy gains during the period amid continued evidence of strong U.S. economic growth with modest inflation. After a brief period of market volatility in late February and early March, markets rebounded quickly on hopes of monetary easing by the Federal Reserve. While U.S. corporate profit growth showed signs of slowing, robust mergers and acquisitions and private equity transactions continued to provide key valuation support to equities in the U.S. and around the globe.

Portfolio Strategy

There were no substantial changes to the portfolio's composition or strategy during the period. Janus Smart Portfolio – Growth is structured as a "fund of funds" portfolio that provides investors with broad, diversified exposure to various types of investments with a clear emphasis on growth. The Portfolio is also designed to blend the two core competencies Janus enjoys as an organization: mathematically driven, risk-managed strategies and fundamentally driven, growth-oriented investments. I believe that combining these two very different approaches in a single investment can produce a Portfolio with a unique and powerful performance profile.

Our investment process involves setting return expectations for a broad range of possible Janus mutual funds that the analyst team and I believe best represents the full opportunity set available to today's investor. Then, acting in conjunction with an outside consultant, we establish an ideal "model" portfolio based upon the specific risk/return objective of Janus Smart Portfolio – Growth. Finally, we select our desired exposure.

At period end, approximately 81.3% of the Portfolio was allocated to the equity funds, with the remaining 18.7% of the Portfolio invested in the fixed-income funds. Under normal market conditions, a broadly diversified portfolio attempts to buffer the risk that an all-stock portfolio might ordinarily bear. The allocations assigned to each selected underlying fund were consistent with our view of market conditions and the long-term trade-off between risk and reward that each of these investment types represents. However, as a result of changing market conditions, both the mix of underlying funds and the allocations to these funds will change from time to time.

Portfolio Review

The majority of the equity fund holdings gained. One standout was the position in Janus Overseas Fund, which benefited from strength in international markets – particularly in developing countries such as China, India and South Korea. Just as with the bond fund holdings, we invested in Janus Overseas Fund for very specific reasons that have as much to do with our desired asset allocation targets as they did with its ability to potentially generate returns. As the Portfolio's primary source of non-U.S. exposure, I felt it was critical that Janus Overseas Fund maintain a return profile that was more in synch with international markets than it was with U.S. markets, thereby providing the geographical diversification I feel is necessary for the Portfolio to deliver on its intended asset allocation goals. This period, Janus Overseas Fund proved up to that task. The investments in Janus Twenty Fund and Janus Research Fund also posted strong numbers in the period.

While positions in Janus Flexible Bond Fund and Janus High-Yield Fund performed well for us in previous periods, these positions were among our weaker performers this period. This is not altogether surprising given the current environment for bonds, which is characterized by an inverted yield curve and lingering unease about the direction of interest rates in general. More specific to the high-yield market, unusually tight credit spreads also acted as a headwind for this specialized and sometimes challenging segment of the fixed-income market. Given all this, however, the Fund's allocation to bonds continued to fulfill its primary purpose, which is to act as a counter-balance to the natural volatility that our equity positions introduce into returns. For that reason, I intend for them to continue to play an important role in the portfolio.

Investment Strategy and Outlook

We plan to continue to monitor market conditions as well as the performance and composition of the underlying funds in which we invest for directional cues. However, all Janus Smart Portfolios (including this one) are designed to be long-term investment vehicles, and we firmly believe that excessive trading in response to short-term market conditions or to chase the latest investment fad almost always proves counter-productive. Accordingly, we expect to make only relatively modest changes to the portfolio in coming months.

Instead, we will remain focused on trying to ensure that the Portfolio fulfills its mandate of delivering access to some of the best strategies Janus has to offer while at the same time maintaining broad exposure to a wide range of asset classes. It remains a primary goal to provide these things in a professionally allocated, systematically re-balanced and risk-controlled investment vehicle.

In closing, thank you for your investment in Janus Smart Portfolio – Growth.

A Portfolio which redeems or exchanges certain underlying funds' shares held for three months or less may be subject to an underlying fund's 2.00% redemption fee, if any. Effective for underlying fund shares purchased on or after May 15, 2007, the period during which a redemption fee may apply will change from three months to 90 days.

Janus Capital has contractually agreed to waive the Portfolio's total operating expenses (excluding any expenses of an underlying fund, brokerage commissions, interest, taxes, and extraordinary expenses) to a certain limit until at least March 1, 2008. For a period of three years subsequent to the Portfolios' commencement of operations, Janus Capital may recover from each Portfolio, fees and expenses previously waived or reimbursed if that Portfolio's expense ratio, including recovered expenses, falls below the respective expense limit. The expense waiver is detailed in the Statement of Additional Information. Total returns shown include fee waivers and without such waivers total returns would have been lower.

The Portfolio's expense ratios were determined based on average net assets as of the fiscal year ended October 31, 2006. Detailed information is available in the prospectus. Contractual waivers agreed to by Janus Capital are included under "Net Annual Fund Operating Expenses." All expenses are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce transfer agent expenses.

An underlying fund's performance may be affected by risks that include those associated with non-diversification, non-investment grade debt securities, undervalued or overlooked companies, investments in specific industries or countries and potential conflicts of interest with Janus Smart Portfolios. Additional risks to the Portfolio may include those associated with investing in foreign securities, emerging markets, initial public offerings ("IPO"s), derivatives and companies with relatively small market capitalizations. Please see a Janus prospectus or www.janus.com for more information about risk, portfolio holdings and details.

Because Janus Capital is the adviser to the Janus Smart Portfolios and to the underlying funds held within the Portfolios, it is subject to certain potential conflicts of interest when allocating the assets of the Portfolios among underlying Janus funds.

There is no assurance that the investment process will consistently lead to successful investing.

Janus Smart Portfolio – Moderate (unaudited)

Ticker: JSPMX

Fund Snapshot

This asset allocation fund combines funds backed by Janus' fundamental research approach with those using the mathematical approach of INTECH. The portfolio seeks growth of capital and income with approximately 60% allocated to stocks and 40% to bonds and money markets.

Performance Overview

Janus Smart Portfolio – Moderate gained 8.67% for the six-month period ended April 30, 2007. This compares to a return of 8.60% by the S&P 500^® Index, the Portfolio's benchmark for the same period. The Portfolio outpaced the 7.80% return by its secondary benchmark, the internally calculated, hypothetical Moderate Allocation Index. These results were consistent with the Portfolio's objective, which is to provide exposure to both stocks and bonds while emphasizing the potential downside protection and income typically offered by fixed-income securities.

Dan Scherman
portfolio manager

It is important to me that the Portfolio outperform the Moderate Allocation Index, a benchmark that more closely resembles the target asset allocation established for the Portfolio. We accomplished that goal during the period, and we will strive to continue to do so in the future.

Market Review

Portfolio Strategy

There were no substantial changes to the Portfolio's composition or strategy during the period. Janus Smart Portfolio – Moderate is structured as a "fund of funds" portfolio that attempts to provide investors with broad, diversified exposure to various types of investments with an emphasis on modest growth. Our investment process involves setting return expectations for a broad range of Janus mutual funds that we believe best represent the full opportunity set available to today's investor. Then, acting in conjunction with an outside consultant, we establish an ideal "model" portfolio based on the specific risk/return objective of Janus Smart Portfolio – Moderate. Finally, we select appropriate Janus funds that replicate our desired exposure.

Under normal market conditions, a broadly diversified portfolio attempts to buffer the risk that a stock-only portfolio might ordinarily bear. The allocations assigned to each selected underlying fund were consistent with our view of market conditions and the long-term trade-off between risk and reward potential that each of these investment types represents. However, as a result of changing market conditions, both the mix of underlying funds and the allocations to these funds will change from time to time.

At period-end, about 62% of the Portfolio was allocated to stocks, with the remaining 38% of the Portfolio invested in bonds, cash and other fixed-income securities. Under normal market conditions, this allocation of assets should buffer the risk that an all-stock portfolio might ordinarily bear and is intended to be consistent with our view on both market conditions and long-term risk-reward profiles.

Portfolio Review

The majority of our equity fund holdings reported gains during the period. One standout was our position in Janus Overseas Fund, which benefited from strength in international markets – particularly in developing countries such as China, India and South Korea. Just as with the bond fund holdings, the Portfolio invested in Janus Overseas Fund for very specific reasons that had as much to do with the desired asset allocation targets as with its ability to generate potential returns.

This year, Janus Overseas Fund proved up to that task. Janus Research Fund and Janus Twenty Fund, which have larger-cap holdings, also posted strong numbers in the period.

The Portfolio's returns reflected some of the market's broader themes during the period. While our positions in

10 Janus Smart Portfolios April 30, 2007

(unaudited)

Janus Flexible Bond Fund, Janus Short-Term Bond Fund and Janus High-Yield Fund performed well for us in past periods, in the most recent environment the bond funds were collectively our weaker performers. Performance among the bond holdings lived up to expectations, however, and we believe these funds will continue to play an important role in the Portfolio.

Finally, investors continued to favor large-cap value-oriented stocks at the expense of large-cap growth stocks. That trend was visible in the calendar year-to-date outperformance of Janus Adviser INTECH Risk-Managed Value Fund over Janus Adviser INTECH Risk-Managed Growth Fund. By maintaining similar exposures to each of these funds, we hope to participate equally, whether investors continue to prefer large-cap value stocks or if – as some investors expect – the pendulum ultimately swings back toward large-cap growth stocks.

Investment Strategy and Outlook

We will continue to monitor market conditions as well as the performance and composition of the underlying funds in which we invest for directional cues. However, all Janus Smart Portfolios (including this one) are designed to be long-term investment vehicles, and we firmly believe that excessive trading in response to short-term market conditions or to chase the latest investment fad almost proves counter-productive. Accordingly, we expect to make only relatively modest changes to the Portfolio in coming months.

The equity portion of the Portfolio also mirrored broader market trends. For example, international stocks continued to outshine domestic stocks as they had done for several years running. In particular, stocks domiciled in emerging markets such as Brazil and India were among the best performers. The investment in Janus Overseas Fund, which was the Portfolio's largest equity holding during the period, gained substantially in part due to its exposure to these rapidly growing regions. Similarly, the Portfolio benefited from its investment in Janus Contrarian Fund, which held a sizable portion of its assets in companies located outside the United States.

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Janus Smart Portfolio - Growth, Janus Smart Portfolio - Moderate and Janus Smart Portfolio - Conservative, (collectively the "Portfolios" and individually a "Portfolio") are series Portfolios. The Portfolios each operate as a "fund of funds," meaning substantially all of the Portfolios' assets will be invested in other Janus mutual funds (the "underlying funds"). Each Portfolio invests in a variety of underlying funds to pursue a target allocation of stocks and bonds, and may also invest in money market instruments or cash/cash equivalents. The Portfolios are part of Janus Investment Fund (the "Trust"), which was organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the "1940 Act") as an open-end management investment company. The Trust has thirty funds. Each of the Portfolios in this report is classified as diversified as defined in the 1940 Act. The Portfolios are no-load investments.

Underlying Funds

Each Portfolio invests in a variety of underlying funds to pursue a target allocation of stocks and bonds, and may also invest in money market instruments or cash/cash equivalents. Each Portfolio has a target allocation, which is how each Portfolio's investments generally will be allocated among the major asset classes over the long term, as well as normal ranges within which each Portfolio's asset class allocations generally will vary over short-term periods. The normal asset allocation ranges are as follows: (1) 75%-85% stocks and 15%-25% bonds and money market instruments for Janus Smart Portfolio - Growth; (2) 55%-65% stocks and 35%-45% bonds and money market instruments for Janus Smart Portfolio - Moderate; and (3) 35%-45% stocks and 55%-65% bonds and money market instruments for Janus Smart Portfolio - Conservative. A brief description of each of the underlying funds that the Portfolios may invest in are as follows.

INVESTMENTS IN CASH EQUIVALENTS

JANUS MONEY MARKET FUND - INVESTOR SHARES seeks maximum current income to the extent consistent with stability of capital. The fund pursues its investment objective by investing primarily in high quality debt obligations and obligations of financial institutions. Debt obligations may include commercial paper, notes and bonds, and variable amount master demand notes. Obligations of financial institutions include certificates of deposit and time deposits.

CASH EQUIVALENTS include money market instruments (such as certificates of deposit, time deposits, and repurchase agreements), shares of affiliated money market funds or high-quality debt obligations (such as U.S. Government obligations, commercial paper, and other short-term corporate instruments).

The following accounting policies have been consistently followed by the Portfolios and are in conformity with accounting principles generally accepted in the United States of America in the investment company industry.

Investment Valuation

A Portfolio's net asset value ("NAV") is calculated based upon the NAV of each underlying fund in which the Portfolio invests on the day of valuation. In the case of underlying funds with share classes, the NAV for each class is computed by dividing the total value of securities and other assets allocated to the class, less liabilities allocated to that class, by the total number of shares outstanding for the class.

Securities held by the underlying funds are valued at the last sale price or the official closing price for securities traded on a principal securities exchange (U.S. or foreign) and on the NASDAQ National Market. Securities held by the underlying funds that are traded on over-the-counter markets and listed securities for which no sales are reported are valued at the latest bid price (or yield equivalent thereof) obtained from one or more dealers transacting in a market for such securities or by a pricing service approved by the underlying funds' Trustees. Short-term securities held by the underlying funds with maturities of 60 days or less may be valued at amortized cost, which approximates market value. Investments held by the underlying money market fund are valued at the amortized cost method of valuation permitted in accordance with Rule 2a-7 under the 1940 Act and certain conditions therein. Under the amortized cost method, which does not take into account unrealized capital gains or losses, an instrument is initially valued at its cost and thereafter assumes a constant accretion/amortization to maturity of any discount or premium. Debt securities held by underlying funds with a remaining maturity of greater than 60 days are valued in accordance with the evaluated bid price supplied by the pricing service. The evaluated bid price supplied by the pricing service is an evaluation that reflects such factors as security prices, yields, maturities and ratings. Foreign securities and currencies held by the underlying funds are converted to U.S. dollars using the applicable exchange rate in effect as of the daily close of the New York Stock Exchange ("NYSE"). When market quotations are not readily available or deemed unreliable, or events or circumstances that may affect the value of portfolio securities held by the underlying funds are identified between the closing of their principal markets and the time the NAV is determined, securities held by the underlying funds may be valued at fair value as determined in good faith under procedures established by and under the supervision of the Portfolios' Trustees. The underlying funds may use a systematic fair valuation model provided by an independent third party to value international equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the NYSE.

Investment Transactions and Investment Income

Investment transactions are accounted for as of the date purchased or sold (trade date). Gains and losses are determined on the identified cost basis, which is the same basis used for federal income tax purposes.

Income and capital gain distributions, if any, from the underlying funds are recorded on the ex-dividend date. Certain dividends from foreign securities held by the underlying funds will be recorded as soon as the Trust is informed of the dividend if such information is obtained subsequent to the ex-dividend date. Interest income of the underlying funds is recorded on the accrual basis and includes amortization of premiums and accretion of discounts.

Expenses

Each Portfolio bears expenses incurred specifically on its behalf. Additionally, each Portfolio, as a shareholder in the underlying funds, will also indirectly bear its pro rata share of the expenses incurred by the underlying funds. Each Portfolio bears expenses incurred specifically on its behalf as well as a portion of general expenses, which may be allocated pro rata to each of the funds in the Trust.

Securities Lending

Under procedures adopted by the Trustees, the underlying funds may lend securities to qualified parties (typically brokers or other financial institutions) who need to borrow securities in order to complete certain transactions such as covering short sales, avoiding failures to deliver securities or completing arbitrage activities. The underlying funds may seek to earn additional income through securities lending. There is the risk of delay in recovering a loaned security or the risk of loss in collateral rights if the borrower fails financially. In addition, Janus Capital makes efforts to balance the benefits and risks from granting such loans.

Janus Smart Portfolios April 30, 2007 29

Notes to Financial Statements (unaudited) (continued)

The underlying funds do not have the right to vote on securities while they are being lent; however, the underlying funds may attempt to call back the loan and vote the proxy. All loans will be continuously secured by collateral which may consist of cash, U.S. Government securities, domestic and foreign short-term debt instruments, letters of credit or such other collateral permitted by the Securities and Exchange Commission ("SEC"). Cash collateral may be invested in affiliated money market funds or other accounts advised by Janus Capital to the extent consistent with exemptive relief obtained from the SEC or as permitted by the 1940 Act and rules promulgated thereunder. Cash collateral may also be invested in unaffiliated money market funds or other accounts advised by Janus Capital to the extent consistent with exemptive relief obtained from the SEC or as permitted by the 1940 Act and rules promulgated thereunder. Cash collateral may also be invested in unaffiliated money market funds or other accounts.

State Street Bank and Trust Company (the "Lending Agent") may also invest the cash collateral of the underlying funds in the State Street Navigator Securities Lending Prime Portfolio or investments in unaffiliated money market funds or accounts, mutually agreed to by the underlying funds and the Lending Agent, that comply with Rule 2a-7 of the 1940 Act relating to money market funds.

The value of the collateral must be at least 102% of the market value of the loaned securities of the underlying funds that are denominated in U.S. dollars and 105% of the market value of the loaned securities of the underlying funds that are not denominated in U.S. dollars. Loaned securities and related collateral of the underlying funds are marked-to-market each business day based upon the market value of the respective securities at the close of business, employing the most recent available pricing information. Collateral levels are then adjusted based on this mark-to-market evaluation.

Interfund Lending

Pursuant to an exemptive order received from the SEC, the underlying funds may be party to an interfund lending agreement between the underlying funds and other Janus Capital sponsored mutual funds, which permits them to borrow or lend cash at a rate beneficial to both the borrowing and lending funds. Outstanding borrowings from all sources totaling 10% or more of a borrowing fund's total assets must be collateralized at 102% of the outstanding principal value of the loan; loans of less than 10% may be unsecured.

Forward Currency Transactions

The underlying funds may enter into forward currency contracts in order to reduce their exposure to changes in foreign currency exchange rates on their foreign portfolio holdings and to lock in the U.S. dollar cost of firm purchase and sale commitments for securities denominated in or exposed to foreign currencies. A forward currency exchange contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated rate. Gains or losses arise from the difference between the U.S. dollar cost of the original contract and the value of the foreign currency in U.S. dollars upon closing a contract.

Forward currency contracts held by the underlying funds are fully collateralized by other securities. The collateral is evaluated daily to ensure its market value equals or exceeds the current market value of the corresponding forward currency contracts.

Mortgage Dollar Rolls

The underlying Janus Flexible Bond Fund, Janus High-Yield Fund and Janus Short-Term Bond Fund may enter into "mortgage dollar rolls." In a "mortgage dollar roll" transaction, the underlying fund sells a mortgage-related security (such as a Government National Mortgage Association ("GNMA") security) to a dealer and simultaneously agrees to repurchase a similar security (but not the same security) in the future at a pre-determined price. The underlying fund will not be entitled to receive interest and principal payments while the dealer holds the security. The difference between the sale price and the future purchase price is recorded as an adjustment to investment income of the underlying fund.

The underlying fund's obligations under a dollar roll agreement must be covered by cash, U.S. Government securities or other liquid high-grade debt obligations equal in value to the securities subject to repurchase by the underlying fund, maintained in a segregated account. To the extent that the underlying fund collateralizes its obligations under a dollar roll agreement, the asset coverage requirements of the 1940 Act will not apply to such transactions. Furthermore, under certain circumstances, an underlying mortgage-backed security that is part of a dollar roll transaction may be considered illiquid.

Successful use of mortgage dollar rolls depends on the underlying fund's ability to predict interest rates and mortgage payments. Dollar roll transactions involve the risk that the market value of the securities the underlying fund is required to purchase may decline below the agreed upon repurchase price.

Securities Traded on a To-Be-Announced Basis

The underlying Janus Flexible Bond Fund, Janus High-Yield Fund and Janus Short-Term Bond Fund may trade securities on a to-be-announced ("TBA") basis. In a TBA transaction, the underlying fund commits to purchasing or selling securities for which specific information is not yet known at the time of the trade, particularly the face amount and maturity date in

30 Janus Smart Portfolios April 30, 2007

GNMA, Federal National Mortgage Association ("FNMA") and/or Federal Home Loan Mortgage Corporation ("FHLMC") transactions.

Securities purchased on a TBA basis are not settled until they are delivered to the underlying fund, normally 15 to 45 days later. Beginning on the date the underlying fund enters into a TBA transaction, cash, U.S. Government securities or other liquid high-grade debt obligations are segregated in an amount equal in value to the purchase price of the TBA security. These transactions are subject to market fluctuations and their current value is determined in the same manner as for other securities.

Bank Loans

The underlying Janus Balanced Fund, Janus Flexible Bond Fund, Janus High-Yield Fund and Janus Short-Term Bond Fund may invest in bank loans, which include institutionally traded floating rate securities generally acquired as an assignment or participation interest in loans originated by a bank or financial institution (the "Lender") that acts as agent for all holders. The agent administers the terms of the loan, as specified in the loan agreement. When investing in a loan participation, the underlying fund has the right to receive payments of principal, interest and any fees to which it is entitled only from the Lender selling the loan agreement and only upon receipt by the Lender of payments from the borrower. The underlying fund generally has no right to enforce compliance with the terms of the loan agreement with the borrower. Assignments and participations involve credit, interest rate, and liquidity risk. Interest rates on floating rate securities adjust with general interest rate changes and/or issuer credit quality. The interest rates paid on a floating rate security in which the underlying fund invests generally are readjusted every 45-60 days, on average, to an increment over a designated benchmark rate, such as the one-month, three-month, six-month or one-year London Interbank Offered Rate ("LIBOR").

The underlying fund may have difficulty trading assignments and participations to third parties. There may be restrictions on transfer and only limited opportunities may exist to sell such securities in secondary markets. As a result, the underlying fund may be unable to sell assignments or participations at the desired time or may be able to sell only at a price less than fair market value. The underlying fund utilizes an independent third party to value individual bank loans on a daily basis.

Futures Contracts

The underlying funds, except Janus Money Market Fund, may enter into futures contracts. The underlying funds intend to use such derivative instruments to hedge or protect from adverse movements in securities prices, currency rates or interest rates. In addition, some of the underlying funds may use futures contracts to gain exposure to the stock market pending investment of cash balances or to meet liquidity needs. The use of futures contracts may involve risks such as the possibility of illiquid markets or imperfect correlation between the value of the contracts and the underlying securities, or that the counterparty will fail to perform its obligations.

Futures contracts are marked-to-market daily, and the daily variation margin is recorded as a receivable or payable. When a contract is closed, a realized gain or loss is recorded by the underlying funds equal to the difference between the opening and closing value of the contract. Generally, futures contracts are marked-to-market (i.e., treated as realized and subject to distribution) for federal income tax purposes at fiscal year end. Securities of the underlying funds are segregated as collateral for market value on futures contracts. Such collateral is in the possession of the underlying funds' custodian.

Options Contracts

The underlying funds, except Janus Money Market Fund, may purchase or write put and call options on futures contracts or foreign currencies in a manner similar to that in which futures or forward contracts on foreign currencies will be utilized, and on portfolio securities for hedging purposes or as a substitute for an investment. The underlying funds generally invest in options to hedge against adverse movements in the value of portfolio holdings.

When an option is written, the underlying funds receive a premium and become obligated to sell or purchase the underlying security at a fixed price, upon exercise of the option. In writing an option, the underlying funds bear the market risk of an unfavorable change in the price of the security underlying the written option. Exercise of an option written by the underlying funds could result in the underlying funds buying or selling a security at a price different from the current market value.

The risk in writing a call option is that the underlying funds give up the opportunity for profit if the market price of the security increases and the option is exercised. The risk in writing a put option is that the underlying funds may incur a loss if the market price of the security decreases and the option is exercised. The risk in buying an option is that the underlying funds pay a premium whether or not the option is exercised. The use of such instruments may involve certain additional risks as a result of unanticipated movement in the

Janus Smart Portfolios April 30, 2007 31

Notes to Financial Statements (unaudited) (continued)

market. A lack of correlation between the value of an instrument underlying an option and the asset being hedged, or unexpected adverse price movements, could render the underlying funds' hedging strategy unsuccessful. In addition, there can be no assurance that a liquid secondary market will exist for any option purchased or sold.

Short Sales

The underlying funds, with the exception of INTECH Risk-Managed Stock Fund, Janus Adviser INTECH Risk-Managed Growth Fund and Janus Adviser INTECH Risk-Managed Value Fund, may engage in "short sales against the box." Short sales against the box involve selling either a security that the underlying funds own, or a security equivalent in kind and amount to the security sold short that the underlying funds have the right to obtain, for delivery at a specified date in the future. The underlying funds may enter into a short sale against the box to hedge against anticipated declines in the market price of portfolio securities. If the value of the securities sold short increases prior to the scheduled delivery date, the underlying funds lose the opportunity to participate in the gain.

The underlying funds, except INTECH Risk-Managed Stock Fund, Janus Adviser INTECH Risk-Managed Growth Fund, Janus Adviser INTECH Risk-Managed Value Fund, Janus Flexible Bond Fund, Janus High-Yield Fund, Janus Short-Term Bond Fund and Janus Money Market Fund – Investor Shares, may also engage in "naked" short sales. Naked short sales involve an underlying fund selling a security it does not own to a purchaser at a specified price. To complete the transaction, the underlying fund must borrow the security to deliver it to the purchaser and buy that same security in the market to return it to the lender. Although the potential for gain is limited to the difference between the price at which the underlying fund sold the security short and the cost of borrowing the security, its potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security. There is no assurance that the underlying fund will be able to close out a short position at a particular time or at an acceptable price. A gain or a loss will be recognized upon termination of a short sale. There is no limit on the size of any loss that an underlying fund may recognize upon termination of a short sale.

Foreign Currency Translations

The underlying funds do not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held at the date of the financial statements. Net unrealized appreciation or depreciation on investments and foreign currency translation arise from changes in the value of assets and liabilities, including investments in securities held at the date of the financial statements, resulting from changes in the exchange rates and changes in market prices of securities held.

Currency gains and losses of the underlying funds are also calculated on payables and receivables that are denominated in foreign currencies. The payables and receivables are generally related to security transactions and income.

Foreign-denominated assets and forward currency contracts of the underlying funds may involve more risks than domestic transactions, including currency risk, political and economic risk, regulatory risk and market risk. Risks may arise from the potential inability of a counterparty to meet the terms of a contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar.

When-issued Securities

The underlying funds may purchase or sell securities on a when-issued or forward commitment basis. The price of the underlying securities and date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Losses may arise due to changes in the market value of the securities or from the inability of counterparties to meet the terms of the contract. In connection with such purchases, the underlying funds may hold liquid assets as collateral with the underlying funds' custodian sufficient to cover the purchase price.

Equity-Linked Structured Notes

The underlying funds may invest in equity-linked structured notes. Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or nonregistered form. An investment in equity-linked structured notes creates exposure to the credit risk of the issuing financial institution, as well as to the market risk of the underlying securities. There is no guaranteed return of principal with these securities and the appreciation potential of these securities may be limited by a maximum payment or call right. In certain cases, equity-linked structured notes may be more volatile and less liquid than less complex securities or other types of fixed-income securities. Such securities may exhibit price behavior that does not correlate with other fixed-income securities.

Initial Public Offerings

Certain underlying funds may invest in initial public offerings ("IPOs"). IPOs and other investment techniques may have a magnified performance impact on an underlying fund with a small asset base. The underlying funds may not experience similar performance as their assets grow.

32 Janus Smart Portfolios April 30, 2007

Additional Investment Risk

Certain underlying funds may be invested in lower-rated debt securities that have a higher risk of default or loss of value since these securities my be sensitive to economic changes, political changes or adverse developments specific to the issuer.

Restricted Security Transactions

Restricted securities held by underlying funds may not be sold except in exempt transactions or in a public offering registered under the Securities Act of 1933. The risk of investing in such securities is generally greater than the risk of investing in the securities of widely held, publicly traded companies. Lack of a secondary market and resale restrictions may result in the inability of an underlying fund to sell a security at a fair price and may substantially delay the sale of the security. In addition, these securities may exhibit greater price volatility than securities for which secondary markets exist.

Dividend Distributions

Dividends and net realized capital gains (if any) are generally declared and distributed annually. The majority of dividends and net realized capital gains distributions from a Portfolio may be automatically reinvested into additional shares of that Portfolio, based upon the discretion of the shareholder.

Estimates

Federal Income Taxes

No provision for income taxes is included in the accompanying financial statements, as the Portfolios intend to distribute to shareholders all taxable investment income and realized gains and otherwise comply with Subchapter M of the Internal Revenue Code applicable to regulated investment companies.

New Accounting Pronouncements

In September 2006, the SEC issued Staff Accounting Bulletin ("SAB") No. 108 "Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements" (SAB 108). SAB 108 requires that public companies utilize a "dual approach" to assessing the quantitative effects of financial misstatements. This dual approach includes both an income statement focused assessment and a balance sheet focused assessment. The guidance in SAB 108 must be applied to annual financial statements for fiscal years ending after November 15, 2006. Management is currently assessing the impact of adopting SAB 108 on each Portfolio's financial position or results of operations.

2. INVESTMENT ADVISORY AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

The Portfolios pay a monthly advisory fee to Janus Capital based upon average daily net assets and calculated at the annual rate of 0.05%.

Janus Capital has agreed until at least March 1, 2008 to reimburse the Portfolios by the amount, if any, that such Portfolio's normal operating expenses in any fiscal year, including the investment advisory fee, but excluding any expenses of an underlying fund, brokerage commissions, interest, taxes and extraordinary expenses, exceed the following annual rates noted below. If applicable, amounts reimbursed to the Portfolios by Janus Capital are disclosed as "Excess Expense Reimbursement" on the Statement of Operations.

Portfolio	Expense Limit Fee %
Janus Smart Portfolio - Growth		0.24
Janus Smart Portfolio - Moderate		0.20
Janus Smart Portfolio - Conservative		0.17

Janus Capital will be entitled to recoup such reimbursement or fee reduction from the Portfolios for a three-year period commencing with the operations of the Portfolios, provided that at no time during such period shall the normal operating expenses allocated to any of the Portfolios, with the exceptions noted above, exceed the percentages stated. This recoup of such reimbursements will expire December 30, 2008. Although Janus Capital is entitled to recoup such reimbursement, Janus Capital has agreed to waive its right of

Janus Smart Portfolios April 30, 2007 33

Notes to Financial Statements (unaudited) (continued)

reimbursement upon termination of the current advisory agreements. For the six-month period ended April 30, 2007, total reimbursement by Janus Capital and the recoupment that may be potentially made to Janus Capital are indicated in the table below:

Portfolio	Reimbursement		Total Recoupment
Janus Smart Portfolio - Growth	$	12,316	$	52,692
Janus Smart Portfolio - Moderate		26,139		71,042
Janus Smart Portfolio - Conservative		37,173		80,208

The Portfolios' expenses may be reduced by expense offsets from an unaffiliated transfer agent. Such offsets are included in Expense and Fee Offsets on the Statement of Operations. The transfer agent fee offsets received during the period reduce Transfer Agent Fees and Expenses. The Portfolios could have employed the assets used by the transfer agent to produce income if they had not entered into an expense offset arrangement.

Janus Services LLC ("Janus Services"), a wholly-owned subsidiary of Janus Capital, is the Portfolios' and the underlying funds' transfer agent. For transfer agency and other services, Janus Services receives a fee at an annual rate of 0.05% of the Portfolio's total net assets. In addition, Janus Services receives $4.00 per open shareholder account for transfer agent services.

Janus Capital has entered into an agreement with Wilshire Associates Inc. (''Wilshire''), a global investment technology, investment consulting, and investment management firm, to act as a consultant to Janus Capital. Wilshire provides research and advice regarding asset allocation methodologies, which Janus Capital uses when determining asset class allocations for the Portfolios. For its consulting services, Janus Capital pays Wilshire an annual fee, payable monthly, that is comprised of a combination of an initial program establishment fee, fixed fee, and an asset-based fee.

Effective January 1, 2006, the Board of Trustees adopted a deferred compensation plan (the "Plan") for independent Trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from the Portfolios. All deferred fees are credited to an account established in the name of the Trustees. The amounts credited to the account then increase or decrease, as the case may be, in accordance with the performance of one or more of the Janus funds that are selected by the Trustees. The account balance continues to fluctuate in accordance with the performance of the selected fund or funds until final payment of all amounts credited to the account. Trustees are allowed to change their designation of mutual funds from time to time. Amounts will be deferred until distributed in accordance with the Plan. No deferred fees were paid to any Trustee under the Plan during the six-month period ended April 30, 2007.

During the six-month period ended April 30, 2007, Janus Services reimbursed Janus Smart Portfolio - Conservative $716 as a result of dilutions caused by incorrectly processed shareholder activity.

During the period ended October 31, 2006, Janus Services reimbursed Janus Smart Portfolio - Moderate $222 as a result of dilutions caused by incorrectly processed shareholder activity.

Certain officers of the Portfolios may also be officers and/or directors of Janus Capital. Such officers receive no compensation from the Portfolios, except for the Portfolios' Chief Compliance Officer. Effective January 1, 2006, the Portfolios began reimbursing the adviser for a portion of the compensation paid to the Chief Compliance Officer of the Portfolios. Total compensation of $56,756 was paid by the Trust during the six-month period ended April 30, 2007. The Portfolios' portion is reported as part of "Other Expenses" on the Statement of Operations.

6. AFFILIATED FUND OF FUNDS TRANSACTIONS

The Portfolios invest in certain mutual funds within the Janus family of funds. While each Portfolio can invest in any or all of the underlying funds, it is expected that each Portfolio will normally invest in only some of the underlying funds at any particular time. All of the realized gain/(loss) recognized by the Portfolios is derived from affiliates. Portfolio's investment in any of the underlying funds may exceed 25% of such Portfolio's total assets. In such instances, the financial statements for the underlying fund may be obtained on the underlying fund's website at www.janus.com. During the six-month period ended April 30, 2007, the Portfolios recorded distributions from affiliated investment companies as dividend income and had the following affiliated purchases and sales:

by a putative class of shareholders of JCGI asserting claims on behalf of the shareholders (Wiggins, et al. v. Janus Capital Group, Inc., et al., U.S. District Court, District of Maryland, Case No. 04-CV-00818). Each of the five complaints initially named JCGI and/or Janus Capital as a defendant. In addition, the following were also named as defendants in one or more of the actions: Janus Investment Fund ("JIF"), Janus Aspen Series ("JAS"), Janus Adviser Series ("JAD"), Janus Distributors LLC, Enhanced Investment Technologies, LLC ("INTECH"), Bay Isle Financial LLC ("Bay Isle"), Perkins, Wolf, McDonnell and Company, LLC ("Perkins"), the Advisory Committee of the Janus 401(k) plan, and the current or former directors of JCGI.

JCGI and Janus Capital, as well as other similarly situated defendants, continue to challenge the statutory authority of the Auditor to bring such an action.

Additionally, information regarding each Portfolio's proxy voting record for the most recent twelve-month period ended June 30 is also available, free of charge, through www.janus.com and from the SEC's website at http://www.sec.gov.

QUARTERLY PORTFOLIO HOLDINGS

APPROVAL OF ADVISORY AGREEMENTS DURING THE PERIOD

In this disclosure, each fund and portfolio of Janus Investment Fund are referred to as "Fund" and collectively as "Funds."

Nature, Extent and Quality of Services

had been consistent with or superior to quality norms in the industry; and that the Funds were likely to benefit from the continued provision of those services. They also concluded that Janus Capital and each subadviser had sufficient personnel, with the appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract and retain well-qualified personnel.

Performance of the Funds

Costs of Services Provided

comparable mutual funds with similar strategies and the fees Janus Capital and the subadviser charge to other clients. The Trustees also concluded that the overall expense ratio of each Fund was reasonable, taking into account the size of the Fund, the quality of services provided by Janus Capital and any subadviser, the investment performance of the Fund and any expense limitations agreed to by Janus Capital.

Economies of Scale

Other Benefits to Janus Capital

The Trustees also considered benefits that accrue to Janus Capital and its affiliates from their relationships with the Funds. They recognized that two affiliates of Janus Capital separately serve the Funds as transfer agent and distributor, respectively, and that the transfer agent receives compensation directly from the non-money market Funds for services provided. The Trustees also considered Janus Capital's past and proposed use of commissions paid by the Funds on their portfolio brokerage transactions to obtain proprietary research products and services benefiting those Funds and/or other clients of Janus Capital, as well as Janus Capital's prior agreement not to use any Fund's brokerage transactions to obtain third party research products or services. The Trustees concluded that Janus Capital's use of "soft" commission dollars of a Fund to obtain proprietary research products and services was consistent with regulatory requirements and guidelines and was likely to benefit the Funds. The Trustees also concluded that, other than the services provided by Janus Capital and its affiliates pursuant to the agreements and the fees to be paid by each Fund therefor, the Funds and Janus Capital may potentially benefit from their relationship with each other in other ways. They concluded that Janus Capital benefits from the receipt of proprietary research products and services acquired through commissions paid on portfolio transactions of the Funds and that the Funds benefit from Janus Capital's receipt of those products and services as well as research products and services acquired through commissions paid by other clients of Janus Capital. They further concluded that success of any Fund could attract other business to Janus Capital or other Janus funds and that the success of Janus Capital could enhance Janus Capital's ability to serve the Funds.

1. PERFORMANCE OVERVIEWS

Performance overview graphs compare the performance of a hypothetical $10,000 investment in each Portfolio with one or more widely used market indices. The hypothetical example does not represent the returns of any particular investment.

When comparing the performance of a Portfolio with an index, keep in mind that market indices do not include brokerage commissions that would be incurred if you purchased the individual securities in the index. They also do not include taxes payable on dividends and interest or operating expenses incurred if you maintained a Portfolio invested in the index.

Average annual total returns are also quoted for each Portfolio. Average annual total return is calculated by taking the growth or decline in value of an investment over a period of time, including reinvestment of any dividends, distributions and capital gains, then calculating the annual compounded percentage rate that would have produced the same result had the rate of growth been constant throughout the period. Average annual total return does not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or redemptions of Portfolio shares.

Pursuant to federal securities rules, expense ratios shown in the performance chart reflect subsidized and unsubsidized ratios for the past fiscal year. The total annual fund operating expenses ratio is gross of any fee waivers, reflecting a Portfolio's unsubsidized expense ratio. The net annual fund operating expenses ratio (if applicable) includes contractual waivers of Janus Capital and reflects a Portfolio's subsidized expense ratio. Both the total annual fund operating expenses ratio and net annual fund operating expenses ratio are based on average net assets as of the fiscal year ended October 31, 2006. The ratios also include expenses indirectly incurred by the Portfolio as a result of investing in other investment companies or pooled investments, which are not reflected in the "Financial Highlights" of this report. As a result, these ratios may be higher or lower than those shown in the "Financial Highlights" in this report. All expenses are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

2. SCHEDULES OF INVESTMENTS

Following the performance overview section is each Portfolio's Schedule of Investments. This schedule reports the types of securities held in each Portfolio on the last day of the reporting period. Holdings are subject to change without notice.

The value of each security is quoted as of the last day of the reporting period.

3. STATEMENT OF ASSETS AND LIABILITIES

This statement is often referred to as the "balance sheet." It lists the assets and liabilities of the Portfolios on the last day of the reporting period.

The Portfolios' assets are calculated by adding the value of the securities owned, the receivable for securities sold but not yet settled, the receivable for dividends declared but not yet received on underlying fund shares owned and the receivable for Portfolio shares sold to investors but not yet settled. The Portfolios' liabilities include payables for securities purchased but not yet settled, Portfolio shares redeemed but not yet paid and expenses owed but not yet paid. Additionally, there may be other assets and liabilities.

The section entitled "Net Assets Consist of" breaks down the components of the Portfolios' net assets. Because Portfolios must distribute substantially all earnings, you'll notice that a significant portion of net assets is shareholder capital.

The last section of this statement reports the net asset value ("NAV") per share on the last day of the reporting period. The NAV is calculated by dividing the Portfolios' net assets (assets minus liabilities) by the number of shares outstanding.

4. STATEMENT OF OPERATIONS

This statement details the Portfolios' income, expenses, gains and losses on securities, and appreciation or depreciation of current Portfolio holdings.

The first section in this statement, entitled "Investment Income," reports the dividends earned from underlying fund shares and interest earned from interest-bearing securities in the Portfolios.

The next section reports the expenses and expense offsets incurred by the Portfolios, including the advisory fee paid to the investment adviser, transfer agent fees and expenses, and printing and postage for mailing statements, financial reports, prospectuses and other expenses. Expense offsets, if any, are also shown.

The last section lists the increase or decrease in the value of securities held in the Portfolios. Portfolios realize a gain (or loss) when they sell their position in a particular security. An unrealized gain (or loss) refers to the change in net appreciation or depreciation of the Portfolios during the reporting period. "Net Realized and Unrealized Gain/(Loss) on Investments" is affected both by changes in the market value of Portfolio holdings and by gains (or losses) realized during the reporting period.

5. STATEMENT OF CHANGES IN NET ASSETS

This statement reports the increase or decrease in the Portfolios' net assets during the reporting period. Changes in the Portfolios' net assets are attributable to investment operations, dividends, distributions and capital share transactions. This is important to investors because it shows exactly what caused the Portfolios' net asset size to change during the period.

The first section summarizes the information from the Statement of Operations regarding changes in net assets due to the Portfolios' investment performance. The Portfolios' net assets may also change as a result of dividend and capital gains distributions to investors. If investors receive their dividends in cash, money is taken out of the Portfolio to pay the distribution. If investors reinvest their dividends, the Portfolios' net assets will not be affected. If you compare each Portfolio's "Net Decrease from Dividends and Distributions" to the "Reinvested dividends and distributions," you'll notice that dividend distributions had little effect on each Portfolio's net assets.

The reinvestment of dividends is included under "Capital Share Transactions." "Capital Shares" refers to the money investors contribute to the Portfolios through purchases or withdrawals via redemptions. The Portfolios' net assets will increase and decrease in value as investors purchase and redeem shares from the Portfolios.

6. FINANCIAL HIGHLIGHTS

This schedule provides a per-share breakdown of the components that affect a Portfolio's NAV for current and past reporting periods. Not only does this table provide you with total return, it also reports total distributions, asset size, expense ratios and portfolio turnover rate.

The first line in the table reflects the NAV per share at the beginning of the reporting period. The next line reports the net investment income per share, which comprises dividends and interest income earned on securities held by the Portfolio. Following is the total of gains/(losses), realized and unrealized. Dividends and distributions are then subtracted to arrive at the NAV per share at the end of the period.

The next line reflects the average annual total return reported the last day of the period.

Also included are the expense ratios, or the percentage of net assets that were used to cover operating expenses during the period. Expense ratios vary across the Portfolios for a number of reasons, including the differences in management fees, the average shareholder account size and the frequency of dividend payments.

The Portfolios' expenses may be reduced through expense reduction arrangements. These arrangements may include the use of transfer agent fee offsets. The Statement of Operations reflects total expenses before any such offset, the amount of the offset and the net expenses. The expense ratios listed in the Financial Highlights reflect total expenses prior to any expense offsets (gross expense ratio) and after the expense offsets (net expense ratio). Both expense ratios reflect expenses after waivers (reimbursements), if applicable.

The ratio of net investment income/(loss) summarizes the income earned less expenses divided by the average net assets of a Portfolio during the reporting period. Don't confuse this ratio with a Portfolio's yield. The net investment income ratio is not a true measure of a Portfolio's yield because it doesn't take into account the dividends distributed to the Portfolio's investors.

The next figure is the portfolio turnover rate, which measures the buying and selling activity in a Portfolio. Portfolio turnover is affected by changes in the target allocation. A 100% rate implies that an amount equal to the value of the entire portfolio is turned over in a year; a 50% rate means that an amount equal to the value of half the portfolio is traded in a year; and a 200% rate means that an amount equal to the value of the portfolio is traded every six months.
