Co-Chief Investment Officers’ Letter to the Shareholders

Jonathan Coleman

Co-Chief

Investment Officer

Gibson Smith

Co-Chief

Investment Officer

Dear Shareholders,

Challenging economic conditions have been the dominant theme for the financial markets over the past several months. Despite recent volatility, our investment team has maintained a relentless focus on our fundamental, bottom-up research process and has continued to discover compelling investment opportunities for our shareholders.

Major Market Themes

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above their mid-March lows, stocks were broadly lower over the six months ended April 30, 2008. The Russell 1000^® Index declined 9.54%, the Russell 2000^® Index was down 12.92% and the Morgan Stanley Capital International (MSCI) All Country World Index^SM gave up 9.47% during the period. Fixed-income markets proved to be volatile over the period with the Lehman Brothers Aggregate Bond Index up 4.08% and the Lehman Brothers High-Yield Bond Index lost 0.74% over the period.

Additional write-offs related to the loose lending practices over the previous 36 months, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Uncertain market conditions resulted in interest rates hitting five-year lows with the 10-Year Treasury Note touching 3.33%. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the funding and credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept, allowed for broker/dealers to borrow directly from the Fed and played an instrumental role in JP Morgan Chase’s purchase of near-defunct Bear Stearns. All of these moves were vitally important toward stabilizing the financial system while allowing for the recovery process to continue. By the end, the Fed had lowered its target interest rate from 4.50% to 2.00% during the period.

Following the March lows, the equity market’s rally at the end of the six-month period can be attributed to the moves by the Fed and, in part, to improving sentiment as investors began to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs continued to weigh on the market.

Performance Notables

For the one-year period ended April 30, 2008, 77% of Janus’ retail funds ranked within Lipper’s top two quartiles, based upon total returns. The results were even stronger over longer time periods as 87% of our retail funds achieved first- or second-quartile Lipper rankings over three years and 86% ranked in Lipper’s top two quartiles over five years. Furthermore, 78.3% of our retail funds had a 4- or 5-star overall Morningstar Rating^tm as of April 30, 2008, well ahead of the 32.5% of funds for which Morningstar awards 4- or 5-stars in each category. (See complete Lipper rankings on page 3 and complete Morningstar Ratings^tm on page 4).

Investment Team Update

We continue to enhance the breadth of our global stock coverage and work tirelessly to generate solid investment insights in an attempt to deliver superior investment performance. Our hands-on research approach is critical to our stock selection process. As such, the Janus equity research team traveled over 2.9 million miles in 2007 investigating potential stock and bond picks worldwide. This year, we plan to embark on a multi-year strategy to locate certain investment personnel closer to the companies that they research as an important first step in building out our global footprint from a research standpoint.

While our objective is to develop a research edge and invest with conviction in our funds, we seek to do so in a disciplined and thoughtful way by clearly understanding and managing risk in our portfolios. Dan Scherman, Director of Risk and Trading, works continually with our investment management

team to ensure that portfolio risks are intentional and calculated. We believe this analysis is both timely and critical as we navigate today’s challenging markets.

Conclusion

As we look back over the past six months, we are relieved that signs of stabilization appeared in the financial markets as the period came to a close. However, we recognize that there are still significant challenges ahead. Increasing risk aversion has resulted in a significant contraction of credit availability for both consumers and corporations. The tightening of credit, along with declining real estate prices, rising energy prices and a climbing unemployment rate may all create significant economic headwinds in the near future. While unsettling, we believe this is a natural and necessary process of recovery from the excessive risk-taking and loose lending standards that developed over the previous several years in many areas of the credit markets. We feel that the environment will improve as the healing process progresses.

So, as we look ahead, we are paying very close attention to the outlook for the global economy, with a keen focus on slowing growth in the United States and the growth rates of the emerging economies around the globe. As these emerging economies become more prosperous, they may be able to move from economies based exclusively on exports fueling their growth to more balanced models emphasizing both exports and internal consumption of the goods they produce. Over a longer period of time, we believe this creates more stability in the global economy. We are also watching rising energy and commodity prices and their impact on inflationary expectations and the absolute level of interest rates. In addition to interest rates, we are focused on the outlook for the housing market and the implications of changes in home prices on the underlying health of the financial system, believing that the recapitalization of the banking and brokerage sectors is a vitally important element of the healing process.

While market volatility is undoubtedly challenging, it can also create an environment that can result in incredibly compelling investment opportunities. Our top priority is to remain committed to our process of in-depth fundamental research, which has been at the core of our investment process since Janus’ inception in 1969. With this singular focus we strive to deliver consistent long-term results for our shareholders.

Thank you for your continued investment in Janus funds.

Sincerely,

Jonathan Coleman

Data presented reflects past performance, which is no guarantee of future results.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating^TM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of the funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variation in the distribution percentages.)

Useful Information About Your Fund Report

Management Commentaries

The Management Commentaries in this report include valuable insight from each of 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, 2008. As the investing environment changes, so could the managers’ 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, 2007 to April 30, 2008.

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 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, dividends, taxes and extraordinary expenses, including, but not limited to, acquired fund fees and expenses, to certain limits until at least March 1, 2009. Expenses in the example reflect 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.

Performance Overview

For the six-month period ended April 30, 2008, Janus Fund returned (9.20)%, outperforming its primary benchmark, the Russell 1000^® Growth Index, which returned (9.28)%. The Fund also outperformed its secondary benchmark, the S&P 500^® Index, which returned (9.64)%.

Economic Summary

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above the mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008.

Additional subprime-related write-offs, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept and played an instrumental role in JP Morgan Chase’s purchase of Bear Stearns. In the end, the Fed lowered its target interest rate from 4.50% to 2.00% during the period.

Overall, mid-cap stocks performed better than large- and small-cap stocks, while growth outperformed value stocks. For the broad market all sectors declined with the exception of energy, which turned in a gain for the six-month period amid record crude oil prices. Meanwhile, financials were the worst performing group, suffering from turmoil in the credit markets and larger-than-expected subprime-related write-downs. Information technology was also among the weakest performers while defensive sectors, like consumer staples, posted small declines. Following the March lows, the equity market’s rally at the end of the period can be attributed in part to improving sentiment as investors began to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs continued to weigh on the market.

Under certain circumstances and market conditions, we may initiate positions in put and call options in order to mitigate the risks and potentially enhance the performance of the portfolio. The volatility in the U.S. equity markets over the past six months provided us with such an opportunity. During the period, we initiated positions in paired option strategies, which encompassed the simultaneous buying and selling of out-of-the-money put and call options on an underlying stock in an attempt to generate some income for the Fund. We used this strategy on a few of our holdings where we would be willing to buy more stock at the put exercise price and sell the shares at the call exercise price. (Please see “Notes to Financial Statements” for information about the hedging techniques used by the Fund.)

Energy and Materials Holdings Aided Performance

Looking more closely at the Fund, sectors that contributed to performance included energy and materials.

In the energy sector integrated oil company Hess was a top performer for the Fund. We added to the position during the period based on what we believe is an impressive number of attractive opportunities around the globe that the company has in its pipeline. We believe the price of the stock does not fully reflect the upside potential of these projects.

Within materials, our agricultural holdings continued to do well. German-based K+S A.G., a leading supplier of specialty fertilizers and plant care, benefited from price increases for its main product, potash. We believe the company is positioned to benefit more than its peers in this environment of rising commodity prices.

Another strong agricultural holding was Syngenta A.G., a Swiss-based leader in crop protection, which has been supported by higher commodity prices for corn and soybeans. Syngenta’s business has been experiencing

improving fundamentals in the Brazilian market as more acreage is planted.

Holdings in Information Technology, Financials and Health Care Detracted from Performance

Our holdings in the information technology, financials and health care sectors held back performance during the period. Information technology (IT) holding Microsoft was the largest detractor during the period. The software maker posted solid quarterly earnings during the period, but the stock declined amid concerns over the company’s bid for Yahoo!. We held the stock during the period given Microsoft’s dominant position in its Office suite, which continues to be a low-cost, high-productivity tool for businesses. We also believe its gaming division has unrecognized potential. Having said that, we were disappointed in Microsoft’s bid for Yahoo! and as a result trimmed the position later in the period. Although we were underweight in the IT sector versus the benchmark, we are looking to increase our exposure.

As mentioned, holdings in the health care sector also hindered performance during the period. Health maintenance organization (HMO) UnitedHealth Group declined in sympathy with other HMO stocks late in the period after a competitor cut its profit forecast due to poor pricing that resulted in higher loss ratios. UnitedHealth later noted that Medicare volume could be lower than expected, which also weighed on the stock. We established and continued to add to the stock during the period, as we believe the core business is performing in line with expectations.

Another detractor in the health care sector was Coventry Health Care. This HMO gave up ground during the period after downwardly revising its profit forecast for the current year, citing higher-than-expected flu treatment-related costs. We trimmed the position slightly, but continued to hold the stock given that the company has been gaining share and generating excess cash.

Home mortgage provider Fannie Mae lost ground after it announced non-cash charges related to adjusting the value of the mortgage loans in its retained portfolio to current market prices due to Generally Accepted Accounting Principals (GAAP) accounting regulations. Given the ongoing risk of mortgage defaults and Fannie Mae’s accounting restrictions, we chose to exit the position.

At the end of the period the Fund was overweight in the consumer staples and materials sectors as compared to the primary benchmark, while underweight in the health care, industrials and information technology sectors. During the period we reduced our weighting in the financials and industrials sectors and increased the weighting in consumer staples.

Other Changes to the Fund

We added some new stocks to the Fund during the period. For example, we purchased Forest Laboratories, which markets key depression and hypertension drugs. We believe the major catalysts to the investment are a replenished pipeline, accelerating earnings and rising free cash flow growth.

We took profits in other names such as metal fabricator Precision Castparts, given our concerns over the slowdown in the airline cycle and the delay of the Boeing 787. We exited the Boeing position for similar reasons. Additionally, we harvested gains in other economically sensitive holdings, trimming names like Sony, transportation services company C.H. Robinson Worldwide, Staples and Nordstrom.

Outlook

Looking ahead, we will be paying close attention to the employment picture, the availability of credit and U.S. consumer confidence, among other things. Should the labor market continue to soften amid continued weakness in the housing market, further slowing in consumer spending is likely. While the government stimulus checks could provide a temporary boost, the current de-leveraging of the U.S. economy could take time to complete, possibly lessening the potential for a sharp rebound in economic activity. Inflation remains a concern for the markets as well, given record commodity prices and its recent elevated level. Although inflation is generally a lagging indicator and should ease with slowing economic growth, it deserves attention given its negative impact and the notion that inflation may limit the Fed’s options to further stimulate economic growth.

Although export growth has been strong, helping to offset domestic weakness, and corporate balance sheets are generally healthy, something that has provided support for equity prices, markets are likely to tread cautiously. Nevertheless, we remain committed to our fundamental investment approach in our effort to find opportunities that we believe represent an attractive risk/reward profile. As always, we will continue to emphasize bottom-up company analysis as our primary tool in our quest to add value for shareholders.

am a 13-year Janus veteran. I am joined by Dan Riff, co-portfolio manager. Similar to David, we invest in large-cap companies that we believe have solid business models, strong cash flows, and high returns on invested capital. Therefore, you should not expect significant changes to the management of the Fund.

14  Janus Growth Funds  April 30, 2008

Janus Enterprise Fund (unaudited) Ticker: JAENX

Fund Snapshot

This fund invests in medium-sized companies that have grown large enough to be well established but are small enough to still have room to grow.

Brian Demain

portfolio manager

Performance Overview

During the six months ended April 30, 2008, Janus Enterprise Fund returned (3.54)%. Meanwhile, the Fund’s primary benchmark, the Russell Midcap^® Growth Index, returned (8.44)%. The Fund’s secondary benchmark, the S&P MidCap 400 Index, returned (6.95)% for the same time period.

Economic Overview

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above the mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008.

Additional subprime-related write-offs, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept and played an instrumental role in JP Morgan Chase’s purchase of Bear Stearns. In the end, the Fed lowered its target interest rate from 4.50% to 2.00% during the period.

Overall, mid-cap stocks performed better than large- and small-cap stocks, while growth outperformed value stocks. All sectors declined with the exception of energy, which turned in a gain for the six-month period amid record crude oil prices. Meanwhile, financials were the worst performing group, suffering from turmoil in the credit markets and larger-than-expected subprime-related write-downs. Information technology was also among the weakest performers while defensive sectors, like consumer staples, posted small declines. Following the March lows, the equity market’s rally at the end of the period can be attributed in part to improving sentiment as investors began to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs continued to weigh on the market.

Energy and Materials Stocks Aided Performance

The largest contributors to the Fund were energy holding EOG Resources and materials holding Potash Corporation of Saskatchewan. EOG announced new discoveries and upped its production guidance during the period. While I believe the company should continue to benefit from rising natural gas prices and the likelihood that the new finds will be accretive to results, I trimmed the holding to accurately reflect our view of the company’s risk/reward profile.

Potash Corporation has the world’s largest excess supply of potash, an ingredient in agricultural fertilizer. Potash-based fertilizer has improved agriculture efficiency and has seen higher demand in the agricultural sector along with increasing demands on the world’s arable land. Additionally, the company has benefited from pricing power, as the end user is generally insensitive to increases in potash prices. With the market for potash tight and the company’s sales fully booked for the first half of 2008, I remain optimistic about the growth prospects at this company but exited the position to appropriately reflect my view of the current risk/reward profile. I added to my position in German potash producer K+S A.G. and established a position in American potash producer Intrepid Potash during the period.

Select Information Technology and Consumer Discretionary Stocks Weighed on Results

Data center and information technology (IT) services provider SAVVIS suffered during the period as the company lowered guidance, adding to a series of mismanaged investor expectations. Additional concerns that increasing supply in the industry will hamper further growth prospects, as well as concern that IT spending could be reduced in an economic slowdown, hindered the stock’s performance. Longer term, I believe SAVVIS is well positioned to take advantage of increased out-sourcing of non-core IT infrastructure. In addition, this business has historically benefited from pricing power and high incremental margins. I added to the position as I believe the company represents a predictable, recurring-revenue, low-churn business with little economic

sensitivity that will likely benefit from pricing power and a strong secular backdrop.

Within the consumer discretionary sector, long-time holding Lamar Advertising suffered in the period as management gave weaker-than-expected revenue guidance on their quarterly call. A slowing economy and concerns about advertising revenue also weighed on the stock price. I continue to believe in the stability and predictability of Lamar’s business. Additionally, I do not believe the stock price at the end of the period reflected the growth prospects associated with transitioning a portion of the advertising business from traditional to digital billboards. I believe the market overreacted to management’s candor and that growth prospects from digital billboards are not adequately reflected in the stock’s valuation. The company continued to generate free cash flow and return of capital to shareholders. Given what I believe to be strong underlying fundamentals, predictability and potential for future growth, I added to the position on the weakness.

Outlook

The U.S. economy has severely decelerated as a function of limited credit availability and the fallout from the housing bubble. This deceleration has been countered with actions by the Fed and Federal government. While we may escape a formal recession, we could see modest economic growth for the next several quarters and perhaps into the beginning of 2009.

Many financial institutions are facing capital shortages that force them to de-lever and rebuild their equity base rather than help create credit for the broader economy. This is impacting small business expansion, which is having secondary impacts on consumers and large corporations. Mortgage rates are elevated, credit cards are slightly harder to get and consumer confidence, as a result, is near a 28-year low.

Housing starts, which peaked at 2.3 million in January 2006, declined to 950,000 as of December 2007. While 950,000 is unsustainably low over the long term, given the housing inventory overhang, we could expect that level to sustain for some time. Residential fixed investment is approximately 5% of Gross Domestic Product (GDP), and absorbing the impact of a 60% drop in housing starts creates a real headwind for 2008.

The Fed and Federal government have both responded aggressively, with rate cuts and stimulus packages, respectively. While the rapid stimulus may encourage moral hazard in the long run, in the coming quarters it should provide a counterbalance to the limited credit availability and housing headwinds. Monetary easing and the bailout of Bear Stearns could have stabilized the credit markets. The stimulus checks sent out by the Federal government could help aid consumption and may help modestly strengthen consumer balance sheets.

Finally, given the increasingly global nature of U.S. companies’ operations, it is important to consider the global backdrop. While Western Europe faces many of the same obstacles as the U.S., the strong growth in Asia and Latin America, driven by increasing globalization and strong commodity prices, is likely to continue. This helps U.S. companies that export, or that supply exporters to those regions.

We expect continued volatility as the market measures the impact of the negative and positive cross-currents to the economic outlook. In the face of this macroeconomic uncertainty, I’ve attempted to position the portfolio so that individual stock decisions outweigh macroeconomic concerns in seeking performance. I continue to try to find sustainable, high-return growth companies that do not depend on the macroeconomic backdrop, whether it is a headwind or a tailwind.

The period reviewed in this letter is the first with me as the Fund’s manager. I assumed management of the Fund on November 1 from Jonathan Coleman. I have nine years of investing experience and three years of working with Jonathan Coleman as an assistant portfolio manager on the Fund, so I come into this role with experience and knowledge of the portfolio.

As shareholders, you should expect a very similar management style to Jonathan’s. I will focus on finding businesses with strong competitive advantages, high and improving returns on invested capital, sustainable smart growth and strong management. I will focus on buying these stocks at what I consider to be attractive valuations. Finally, I will attempt to limit the volatility of the Fund’s returns by emphasizing names that I believe have repeatable and sustainable growth at the top of the portfolio.

The most important element to be aware of in this transition is that I will be backed by the same strong team of Janus analysts who supported the Fund during the past five years of solid performance. This talented, hard-working, diverse group provides a constant flow of new investment ideas, as well as detailed work on existing positions.

Possibly the biggest difference between Jonathan’s management style and mine will be seen in the total number of holdings. I generally hope to run a portfolio with fewer than 100 holdings, which is slightly less than the

16  Janus Growth Funds  April 30, 2008

(unaudited)

number of holdings that Jonathan had. We have been tactically and gradually taking the smallest positions and deciding whether to increase the holding to a size where it can make a meaningful impact on the portfolio, or selling it outright.

I greatly appreciate the trust you are placing in both me and the analyst team at Janus, and I look forward to communicating with you in the coming years.

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.

John Eisinger

portfolio manager

Performance Overview

This is my first letter as manager of Janus Orion Fund. I want to start by thanking you for giving me this opportunity to manage your money. I take this responsibility very seriously and am fully committed to finding and investing in quality securities that compound value creation over the long term. For the six-month period ended April 30, 2008, the Fund returned (5.07)% outperforming its primary benchmark, the Russell 3000^® Growth Index, which returned (9.68)% and its secondary benchmark, the S&P 500^® Index, which returned (9.64)% for the same period.

Investment Philosophy and Process

I officially assumed management of the Fund on January 2, 2008. As this is my first communication with you I thought it would be helpful to talk about my process for managing the Fund. It is managed very similarly to how it always has been. I believe in taking focused positions in a small number of stocks where the investment team and I have a high level of conviction. By uncovering what we see as discrepancies between current stock prices and true intrinsic value through deep, fundamental research, we seek to generate strong, risk-adjusted returns over the long term.

The Fund is a focused growth fund, which means it will typically hold between 20 and 50 stocks with at least 80% invested in the top 20 to 30 positions. Focusing on a core group of holdings is important to me because I believe that is the best way to generate alpha – which means generating returns in excess of its underlying benchmark. The ability to invest with conviction comes from the intensive analysis our research department conduct. The majority of stocks that fall out of this intensive fundamental analysis, and that I am looking to own, fit into two buckets: mis-priced growth and special situations. A mis-priced growth stock results when company-driven change results in higher-than-expected free cash flow growth over the long term. A good example of this between 2004 and 2007 was Apple. Special situations are stocks that are valued in the market based on current financials rather than real asset value or business model potential. An example of this during 2006 and 2007 was information storage company EMC and its VMware subsidiary. Additionally, the Fund may use derivatives, such as buying put options or selling call options, to both hedge market exposure and express views on stocks. Please see the “Notes to Financial Statements” for a discussion of derivatives used by the Fund.

The first four months of the year were very volatile. January was dominated by large sell offs in the market and emergency interest rate cuts by the Federal Reserve (Fed). The uncertainty continued in February and March based on the fear surrounding the ability of several large financial institutions to survive the credit crisis and the impact a failure would have on the broader financial market system. The turning point came when the Fed intervened to arrange the sale of Bear Stearns to JPMorgan Chase. This was important, as the failure of Bear Stearns could have had a catastrophic impact on the overall market.

My strategy throughout was an attempt to marry our strong differentiated research views with the extreme market volatility in order to add to or buy new positions in stocks at very attractive prices. I remained focused on stock-specific fundamentals which enabled me to use the overall fear in the market to the Fund’s advantage. The process begins by trying to understand what the downside risk is of a stock. Based on thorough valuation work I need to be confident that the downside risk in a stock is small, especially relative to its upside potential. I then look at where our estimates of future cash flows for the firm are different from the rest of Wall Street. Our ability to add value – to deliver returns over those of the Fund’s benchmark index – is often predicated on having a different view of the value of a company which is based on that company’s ability to generate cash flow over the long term. Another important metric that I focus on is return on invested capital (ROIC), a measure of how effectively a company used the money invested in its operations. I need to see that ROIC will be improving over time. Ideally, I try to buy stocks that are under-earning (cash flow) or under-returning (ROIC) relative to the business’s potential. The catalyst for change could be a new management team, a new product cycle or just a new focus on improving the business by the existing management, etc. The primary valuation method I use is discounted cash flow (DCF) analysis, which is a valuation method used to estimate the attractiveness of an investment opportunity. DCF analysis uses future free cash flow projections and discounts them (most often using the weighted average cost of capital) to arrive at a present value, which is used to evaluate the potential for investment. If the value arrived at through DCF analysis is higher than the current cost of the investment, the opportunity may be a good one. The last important goal of my portfolio management approach is not just picking good stocks, but

putting them together to form a diversified portfolio that maximizes the overall discount to intrinsic value. Stocks I believe have the best risk/reward profiles are at the top of the portfolio – this potentially maximizes the overall Fund’s discount to intrinsic value. To diversify the portfolio I focus on minimizing the correlation of each stock within the portfolio. Again, it’s not enough to just put together undervalued stocks, but rather to try to put together a portfolio of undervalued stocks that together act in different ways in all markets. I believe this is diversification.

With that in mind, I’d like to give you an example of how I applied those guidelines at the start of this year. Celgene is a biotechnology company primarily focused on the discovery and development of cancer treatments and falls into the mis-priced growth bucket. Its main drug is called Revlimid. In October 2007, the stock traded at over $75 per share, but at the beginning of 2008 the stock was trading in the $40s based on what our research showed was incorrect analysis of short-term competitive noise and prescription trends. Based on our analysis I chose to add to the position at what I considered to be very attractive prices.

A stock that fell in the special situations bucket was Cypress Semiconductor (CY). In addition to manufacturing and selling semiconductor devices, it is the majority owner of a leading solar company, SunPower (SPWR). In October 2007, CY was trading at over $40. The stock fell to under $20 on concerns about some of CY’s end markets and in sympathy with the market-driven decline in SPWR. With CY’s stock around $20, and based on our analysis of the value of SPWR, we were able to buy the core CY business practically for free.

Both stocks are examples where we had a differentiated view of company fundamentals and the ability of all three firms to continue to meet our cash flow estimates while the stocks were systematically sold off with the rest of the market.

Contributors to Performance

For the six months ended April 30, 2008, the two largest contributors to performance were Potash Corporation of Saskatchewan and Hess. Potash Corporation is a supplier of several key components of fertilizer. One of the multi-year themes I like is the increasing demand for agricultural products from both changing global diets and demand for non-traditional energy sources. This has driven overall unit demand for key minerals like phosphate significantly higher than recent history. Our research into the supply and demand dynamics of the industry led us to conclude that the company’s ability to increase prices – and the associated incremental cash flow – was substantial and much higher than expected. Our thesis has played out and price increases continued to come in higher than expected leading to further upward estimate revisions and, we believe, continued undervaluation of the stock.

Hess explores, produces, purchases, transports and sells crude oil and natural gas. Our thesis on the company has been that their newer fields in Brazil, Ghana and the Gulf of Mexico were not being valued correctly by the market. Recent data, primarily in Brazil, suggests that the size of the company’s reserves could be substantially greater than previous estimates. The stock has been helped by strong oil prices, but our analysis and valuation is supported by oil prices substantially lower than today’s spot market.

Detractors from Performance

The largest detractors from performance were Yahoo! and National Financial Partners. Yahoo!’s stock has struggled as the competitive environment has become worse, primarily from Google. There have also been internet usage changes as we’ve been seeing increasing use of websites such as Facebook.com. In my opinion, the best option for Yahoo! would be to sell itself to a company like Microsoft. However, waiting for a takeout is not an investment thesis and so I sold the stock at the beginning of the year before the eventual acquisition attempt by Microsoft, which has subsequently fallen through.

National Financial Partners is an independent distributor of financial services products, primarily insurance. The company reported disappointing results during the first quarter which caused the stock to decline substantially.

Outlook

Going forward I plan to look at stocks that have been sold off heavily, especially in areas such as consumer discretionary, financials and technology. As always, I am looking to leverage our strong research team to uncover stocks that have substantial upside relative to downside. I am cognizant of the risks associated with a deteriorating macro-economic environment in the U.S. and the high risks posed by rising global inflation. The process remains the same: Attempt to find and invest in a small number of stocks where we have a differentiated opinion on the value of the business based on cash flows, with limited downside and substantial upside supported by thorough, disciplined and differentiated research.

Thank you for your continued investment in Janus Orion Fund.

The Fund’s performance may be affected by risks that include those associated with non-diversification, 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 (“IPOs”) and derivatives. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and other details.

Funds that invest in Real Estate Investment Trusts (REITs) may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: legal, political, liquidity and interest rate risks, a decline in the value of real estate, risks related to economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Fund invests in foreign REITs, the Fund may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

Janus Orion Fund held approximately 10.2% of its assets in Brazilian securities as of April 30, 2008 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.

The use of short sales may cause the Fund to have higher expenses than those of other equity funds. Short sales are speculative transactions and involve special risks, including a greater reliance on the investment team’s ability to accurately anticipate the future value of a security. The Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s use of short sales in effect leverages the Fund’s portfolio. The Fund’s use of leverage may result in risks and can magnify the effect of any losses. There is no assurance that a leveraging strategy will be successful.

Returns include reinvestment of dividends from investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

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 unmanaged and are not available for direct investment; therefore their performance does not reflect the expenses associated with the active management of an actual portfolio.

32  Janus Growth Funds  April 30, 2008

Janus Research Fund (unaudited) Ticker: JAMRX

Fund Snapshot

This fund provides investors with broad exposure to what our research team feels are the most dynamic growth opportunities, regardless of company size.

Team Based Approach
Led by Jim Goff
Director of Research

Performance Overview

For the six-month period ended April 30, 2008, Janus Research Fund returned (7.02)%, outperforming its primary benchmark, the Russell 1000^® Growth Index, which returned (9.28)% and its secondary benchmark, the S&P 500^® Index, which returned (9.64)%.

Economic Overview

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above the mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008.

Additional subprime-related write-offs, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations weighed on investor sentiment during the period. Stocks reached their lows in mid-March. Financial markets stabilized somewhat after the Federal Reserve (Fed) aggressively lowered the Federal Funds rate, expanded the collateral it would accept and played an instrumental role in JP Morgan Chase’s purchase of Bear Stearns. In the end, the Fed lowered its target interest rate from 4.50% to 2.00% during the period.

Overall, mid-cap stocks performed better than large- and small-cap stocks, while growth outperformed value stocks. For the broad market all sectors declined with the exception of energy, which turned in a gain for the six-month period amid record crude oil prices. Meanwhile, financials were the worst performing group, suffering from turmoil in the credit markets and larger-than-expected subprime-related write-downs. Information technology was also among the weakest performers while defensive sectors, like consumer staples, posted small declines.

Since February 1, 2006, Janus Research Fund has been team managed, representing the best ideas from Janus’ more than 30 equity analysts and Director of Research Jim Goff oversees the team. Individual analysts primarily drive stock selection, with debate and oversight provided by each one of the seven global sector research teams. We believe there is great power in individual analysts driving investment decisions, as they are most familiar with the stocks they cover. We strive to keep the Fund sector-neutral compared to its primary benchmark, although the Fund has about a 29% non-U.S. exposure. The Fund may also use total return swaps to fully utilize the research process. (Please see “Notes to Financial Statements” for discussion of various hedging techniques used.) The focus is on consistency and on capturing the value of Janus’ research.

Contributors to Fund Performance

The Fund’s outperformance can be attributed to holdings in the energy and industrials sectors. Industrials company Owens-Illinois added to performance as the transformation at this glass container manufacturer continued to produce strong results. The company reported solid performance at the end of 2007 including the positive margin impact of price increases in a moderating cost environment. We believe these powerful economics coupled with management’s continued emphasis on cost control and returns on invested capital should benefit the stock price. Although we believe there is continued upside for Owens-Illinois, we trimmed the position during the period as we think the restructuring plan is increasingly being reflected in the valuation.

Energy company Hess, an addition to the Fund during the period, was one of the top contributors to performance. The company benefited from the rising price of oil during the period, as well as increased appreciation for the future production potential from Hess’ new projects, including deep water projects in the Gulf of Mexico and off the coast of Brazil.

EOG Resources, an oil and gas company, was another strong individual contributor. Looking ahead, EOG has rights to shale formations in Canada, which are similar to its Texas formations. We believe this could be an attractive opportunity for EOG to increase its gas reserves.

Canada-based Potash Corporation of Saskatchewan moved ahead, aided by continued demand and tight supplies. The company continued to benefit from global demand for agricultural products, which we expect will drive further growth in revenue and earnings industry wide. Potash itself is a critical ingredient used in fertilizers for key farming areas like the U.S., Brazil and China. Price increases for the commodity have been enacted for 2008 in many regions, which led to upward revisions in analysts’ estimates and provided a further tailwind for the company’s stock price.

Detractors from Fund Performance

Technology and communications sectors were the main areas of weakness during the period. SiRF Technology Holdings, a supplier of semiconductors used in global positioning systems, was the largest detractor of Fund performance during the period. The stock declined after reporting weaker-than-expected margins in its most recent quarter. A central component of our thesis had been the company’s competitive positioning, but the eroding margins suggested to us that the company’s competitive positioning wasn’t as sustainable as originally thought and we exited the position.

Within communications, data center and information technology (IT) services provider SAVVIS suffered on concerns that increasing supply in the industry could hamper further growth prospects, that IT spending could be reduced in an economic slowdown and mis-steps by management in setting investors expectations. Longer term, we believe SAVVIS is well-positioned to take advantage of increased out-sourcing of non-core IT infrastructure. In addition, we think this recurring revenue business will benefit from pricing power and high incremental margins.

Industrials holding General Electric (GE) was also negatively impacted by the weakening economy. GE stock fell after reporting weaker-than-expected profits from its GE Capital division due to capital market disruptions and the inability to complete asset sales. Given our cautious outlook on the credit markets, we chose to exit our position.

Another detractor during the period was pharmaceutical company Merck. Performance at Merck was driven largely by a report from the American College of Cardiology suggesting that doctors should limit prescriptions for the company’s jointly sold (with Schering-Plough) cholesterol drugs. The report stated that older, cheaper drugs could be just as effective. Last year, the two drug makers sold $5.2 billion of Vytorin and Zetia, combined. We will be watching the developments of Merck closely in the coming months.

Outlook

The Fund remains sector-neutral and we expect stock selection to be a key driver of returns going forward. Volatile markets tend to give many investors a reason to focus on the short term. Therefore, we believe we will see many opportunities for long-term investors to purchase good businesses at attractive prices. Looking ahead, we will continue to invest with conviction in areas where we feel we can develop an edge through research. Through our valuation discipline and focus on risk management, we remain committed to delivering superior long-term results for our clients.

Thank you for your investment in Janus Research Fund.

Janus Triton Fund (unaudited) Ticker: JATTX

Fund Snapshot

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

Performance Overview

For the six-month period ended April 30, 2008,  Janus Triton Fund returned (14.52)%. Meanwhile, the Fund’s benchmark, the Russell 2500^tm Growth Index, returned (11.37)%.

Economic Overview

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above the mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008.

Additional subprime-related write-offs, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept and played an instrumental role in JP Morgan Chase’s purchase of Bear Stearns. In the end, the Fed lowered its target interest rate from 4.50% to 2.00% during the period.

Overall, mid-cap stocks performed better than large- and small-cap stocks, while growth outperformed value stocks. For the broad market all sectors declined with the exception of energy, which turned in a gain for the six-month period amid record crude oil prices. Meanwhile, financials were the worst performing group, suffering from turmoil in the credit markets and larger-than-expected subprime-related write-downs. Information technology was also among the weakest performers while defensive sectors, like consumer staples, posted small declines. Following the March lows, the equity market’s rally at the end of the period can be attributed in part to improving sentiment as investors began to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs continued to weigh on the market.

Key Detractors

Data center and information technology (IT) services provider SAVVIS suffered on concerns that increasing supply in the industry could hamper further growth prospects, IT spending could be reduced in an economic slowdown and mis-steps by management in setting investors expectations. Longer term, we believe SAVVIS is well-positioned to take advantage of increased out-sourcing of non-core IT infrastructure. In addition, we think this recurring revenue business will benefit from pricing power and high incremental margins. As such, we added to our position.

Over the course of the period, shipping company Horizon Lines suffered on rumors of tax changes, a Department of Justice investigation relating to pricing issues in Puerto Rico, increased fuel costs and worries about the economic environment. We feel Horizon’s competitive position remains intact and feel it is likely to improve with new services. We believe the market has overreacted to the concerns and added to the position. In our opinion, stable volumes, pricing power and cash flows continue to make this a compelling risk/reward opportunity.

Key Contributors

Energy company Helmerich & Payne rose slightly over 70% during the period as this oil and gas driller continued to demand premium prices with their flex rigs. The company has locked in more than 50% of their contracts for 2008 and 2009 offering what we believe is good visibility into future results. We did, however, trim the position as the risk/reward profile was less compelling following the strong performance.

Sandridge Energy, an exploration and production company, primarily focused on natural gas rose over 40% during the period as strong production growth coupled with a growing reserve base and higher natural gas prices boosted performance. We opened the position over the course of the period and believe the company’s potential reserves, likely production growth, and competitive position in west Texas make for a compelling risk/reward profile.

Outlook

Looking ahead, we will be paying close attention to the employment picture, the availability of credit and U.S. consumer confidence, among other things. Should the labor market continue to soften amid continued weakness in the housing market, further slowing in consumer spending is likely. While the government stimulus checks could provide a temporary boost, the current de-leveraging of the U.S. economy could take time to complete, possibly lessening the potential for a sharp rebound in economic activity. Inflation remains a concern for the markets as well, given record commodity prices and its recent elevated level. Although inflation is generally a lagging indicator and should ease with slowing economic growth, it deserves attention given its negative impact and the notion that inflation may limit the Fed’s options to further stimulate economic growth.

Although export growth has been strong, helping to offset domestic weakness, and corporate balance sheets are generally healthy, something that has provided support for equity prices, markets are likely to tread cautiously. Nevertheless, we remain committed to our fundamental investment approach in our effort to find opportunities that we believe represent an attractive risk/reward profile. As always, we will continue to emphasize bottom-up company analysis as our primary tool in our quest to add value for shareholders.

Thank you for your investment in Janus Triton Fund.

(“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.) Contractual waivers agreed to by Janus Capital, where applicable, are included in the prospectus 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. The Fund’s total operating expenses did not exceed the expense limit so no waivers were in effect for the most recent period presented.

The Fund’s performance may be affected by risks that include those associated with, 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 (“IPOs”), derivatives and companies with relatively small market capitalizations. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and other details.

Funds that invest in Real Estate Investment Trusts (REITs) may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: legal, political, liquidity and interest rate risks, a decline in the value of real estate, risks related to economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Fund invests in foreign REITs, the Fund may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

The use of short sales may cause the Fund to have higher expenses than those of other equity funds. Short sales are speculative transactions and involve special risks, including a greater reliance on the investment team’s ability to accurately anticipate the future value of a security. The Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s use of short sales in effect leverages the Fund’s portfolio. The Fund’s use of leverage may result in risks and can magnify the effect of any losses. There is no assurance that a leveraging strategy will be successful.

Returns include reinvestment of dividends from net investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

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.

See Notes to Schedules of Investments for index definitions.

The Fund’s portfolio may differ significantly from the securities held in the index. The index is unmanaged and is not available for direct investment; therefore its performance does not reflect the expenses associated with the active management of an actual portfolio.

Janus Growth Funds  April 30, 2008  49

Janus Twenty Fund (unaudited) (closed to new investors) Ticker: JAVLX

Fund Snapshot

This high conviction fund invests primarily in companies we believe have sustainable businesses with large addressable markets that trade at attractive valuations.

Ron Sachs

portfolio manager

Performance Overview

This is my first letter as portfolio manager of Janus Twenty Fund. I took over the Fund on January 1, 2008. For the six-month period ended April 30, 2008, the Fund returned 2.39% versus a return of (9.28)% for the Fund’s primary benchmark, the Russell 1000^® Growth Index. The Fund’s secondary benchmark, the S&P 500^® Index, returned (9.64)% for the period. This outperformance was generated by holdings across a variety of sectors.

Since I am a new manager to many of you, I thought I should spend a little time discussing my investment philosophy. I share my predecessor’s focus on identifying great companies that I believe can grow and compound value over the long term. When the Fund’s previous portfolio manager and I managed different funds, we owned many of the same companies and leveraged the same exceptional team of research analysts. I believe in making the best long-term investment ideas big positions, which normally leads to a concentrated portfolio in terms of the number of positions held in the Fund, and to a low-turnover portfolio due to the length of time we typically hold these select names. I believe protecting the Fund against the downside is critical to delivering long-term results. One key to both downside protection and long-term value creation is identifying the strength and sustainability of a company’s barriers to competition, popularly referred to as a company’s “competitive moat.” I also believe a focus on valuation is key. I adjust position sizes in the Fund in response to the risk/reward profile we identify based on our valuation work. Finally, I avoid making sector or macro-economic “bets.” I look to build a portfolio of companies that I believe can deliver growth in any economic environment and I spend time thinking about the Fund’s overall exposures to sector headwinds and exogenous economic events. I feel this approach helps deliver more consistent performance than some might expect in a portfolio that is invested in 20-30 positions.

What Went Right

Janus’ conviction in a number of the Fund’s bigger holdings drove outperformance. Potash Corporation of Saskatchewan, the world’s largest miner of potash, was a standout performer. We believe that this company is extremely well positioned to deliver pricing and volume growth, as demand for agricultural commodities tend to increase over time. Potash is an essential component of fertilizer and we believe the industry dynamics and barriers to new competitors allow for a business with very strong pricing power over a multi-year cycle.

Hess, a leading energy exploration and production company, was a contributor to performance during the period. Hess’ strong performance was primarily due to the market’s realization that some of Hess’ recent discoveries off the coasts of Brazil and Africa have the potential to be extremely valuable. Our analysts’ ongoing conversations with management and others familiar with these geographies gave us early insight into the potential size of these finds. We continue to believe that Hess is extremely well positioned to grow its resource base and earnings due to its exciting portfolio of discoveries and prospects.

ABB, a leading provider of electricity transmission and distribution products was a new position in the Fund and another important contributor. We were able to take advantage of some fears in the market early this year to build a position. We believe global spending on electric transmission networks will be strong for an extended period as developed markets rebuild their networks after decades of underinvestment. We believe additional demand has come from emerging economies building new electric transmission networks as a foundation for their future economic growth. We believe ABB is the leader in most critical technologies. This leadership was reflected in leading market shares globally and superior profitability. We see a potential for further profitability in the future.

What Went Wrong

There were a few disappointments during the period as well. Google, the leading internet search engine, was a weak performer during the period. Google stock was down on valuation concerns and fears that an economic slowdown would slow growth. We trimmed our exposure to the stock in early 2008 to reflect the risk/reward profile, but have been encouraged by Google’s ability to continue to outgrow the market while sacrificing some revenues in the short term to improve the user experience for both advertisers and search customers. Internet search is proving to be an industry where the leading players have a significant competitive advantage over competitors with smaller market shares – we believe strong market share and strong technology are creating

what may be a sizeable and enduring competitive moat for Google.

Additional detractors were investment banks Bear Stearns and Goldman Sachs Group. Bear Stearns suffered significant losses during the U.S. mortgage meltdown. We exited the position very early in 2008 over concerns that their two key franchises of prime brokerage and fixed-income issuance would be challenged. It proved to be a well-timed sale as the stock declined further.

Despite avoiding the subprime mortgage losses that hit most major financial institutions, Goldman Sachs underperformed during the period because investors feared that future limits on leverage and the potential for shrinking securities markets would temper Goldman Sachs’ future earnings prospects. While these concerns may be valid in the short term, we focus on long-term opportunities for the companies in the Fund. We believe Goldman Sachs has distinguished itself from its peers over many years with better growth and superior returns. We anticipate increased consumption of sophisticated financial products by individuals, governments and corporations globally and believe Goldman Sachs may be well positioned over the long term to profitably deliver these products.

Outlook

There have been some changes to the Fund during the period. I have added some new positions we are particularly excited about, eliminated some positions that do not fit with my investment philosophy and adjusted position sizes to reflect the risk/reward profiles as I view them.

Looking forward, I will continue to focus on individual company fundamentals and build the Fund stock by stock. That said, the macroeconomic environment influences the fundamentals of every company we own and analyze. I believe the U.S. economy is already in a recession. The stock market anticipated this recession in late 2007, cutting the value of many economically sensitive stocks by 30% or more. In early 2008, the cumulative weight of evidence of a U.S. slowdown caused investors around the globe to discount the possibility that the deceleration could be severe and would drag down growth rates globally. This global panic has created some exciting buying opportunities for those of us focused on long-term company fundamentals. I am excited about the growth prospects of the companies we own.

Thank you for your investment in Janus Twenty Fund. I look forward to reporting results in the future.

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 fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2007. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.)

The Fund’s performance may be affected by risks that include those associated with non-diversification, 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 (“IPOs”) and derivatives. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and other details.

The use of short sales may cause the Fund to have higher expenses than those of other equity funds. Short sales are speculative transactions and involve special risks, including a greater reliance on the investment team’s ability to accurately anticipate the future value of a security. The Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s use of short sales in effect leverages the Fund’s portfolio. The Fund’s use of leverage may result in risks and can magnify the effect of any losses. There is no assurance that a leveraging strategy will be successful.

Annual expense ratios include dividends on interest on short sales, which are paid to the lender of borrowed securities. Such expenses will vary depending on whether the securities the fund sells short pay dividends or interest and the amount of such dividends or interest.

Returns include reinvestment of dividends from investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities.

Janus Venture Fund (unaudited) (closed to new investors) Ticker: JAVTX

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 ended April 30, 2008, Janus Venture Fund returned (24.55)%. Meanwhile, the Fund’s primary and secondary benchmarks, the Russell 2000^® Growth Index and the Russell 2000^® Index, returned (14.14)% and (12.92)%, respectively.

Economic Overview

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above the mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008.

Additional subprime-related write-offs, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept and played an instrumental role in JP Morgan Chase’s purchase of Bear Stearns. In the end, the Fed lowered its target interest rate from 4.50% to 2.00% during the period.

Overall, mid-cap stocks performed better than large- and small-cap stocks, while growth outperformed value stocks. For the broad market all sectors declined with the exception of energy, which turned in a gain for the six-month period amid record crude oil prices. Meanwhile, financials were the worst performing group, suffering from turmoil in the credit markets and larger-than-expected subprime-related write-downs. Information technology was also among the weakest performers while defensive sectors, like consumer staples, posted small declines. Following the March lows, the equity market’s rally at the end of the period can be attributed in part to improving sentiment as investors began to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs continued to weigh on the market.

Additionally, small-cap stocks have been under significant pressure since last summer and the period covered in this letter was no exception with the Russell 2000^® Growth Index down over 14%. Pressure from the unwinding of leverage, liquidation of other small-cap players, and short selling have led to a negative impact on many of what we believe to be the highest-quality small-cap growth names. Within this environment, we focused on maintaining a diversified portfolio with what we feel are solid fundamental companies with strong management teams across market sectors and industries. We continue to believe an important measure of a company’s future health is the capability of its management team and how well they navigate these turbulent times.

Under certain circumstances and market conditions, we may initiate positions in put and call options in order to mitigate the risks and potentially enhance the performance of the portfolio. The volatility in the U.S. equity markets over the past six months provided us with such an opportunity. (Please see “Notes to Financial Statements” for information about the hedging techniques used by the Fund.)

Information Technology Holdings Weighed on Performance

The Fund’s underperformance during the period was largely driven by weakness in the information technology sector. NaviSite, a web hosting and design company, was the largest detractor from performance. Much of the downward pressure on the stock occurred in the fourth quarter of 2007 as the company’s results suffered from contract delays during the reporting period. We added to our position on the belief that recurring revenue generated through a subscription-based model offers sustainable growth and that the high free cash flow yield makes for a compelling valuation.

SiRF Technology Holdings also fell short of our expectations during the period. SiRF fell slightly over 75% as the industry landscape changed with a new competitor driving down pricing. We sold the stock as a result of this change in competitive positioning.

Select Financials and Industrials Holdings Aided Performance

In the financials sector Brazil’s largest real estate broker, LPS Brasil-Consultoria de Imoveis S.A., rose more than 25% in the period with much of the move coming at the end of 2007 as the company announced a joint venture to provide mortgages to its customers. In addition to an equal profit sharing agreement, LPS Brasil received an upfront payment equal to 20% of its market cap. We believe the joint venture will help streamline the secondary market for mortgages in Brazil as well as provide a source of future growth for the company. Prior to the announcement of the joint venture, we had confidence in the management team’s ability to create value for shareholders and maintain that view going forward.

Our position in industrials company JA Solar Holdings was one of the top contributors to performance. While the company did offer conservative guidance toward the end of 2007, we believe over the long term their access to silicon will benefit their input costs. Along with what we believe to be a large addressable market in solar and alternative energy, we think JA Solar is a compelling long-term growth story. We added to JA Solar during the period as we believe the market is underestimating the future potential of alternative energy businesses.

Outlook

Looking ahead, we will be paying close attention to the employment picture, the availability of credit and U.S. consumer confidence, among other things. Should the labor market continue to soften amid continued weakness in the housing market, further slowing in consumer spending is likely. While the government stimulus checks could provide a temporary boost, the current de-leveraging of the U.S. economy could take time to complete, possibly lessening the potential for a sharp rebound in economic activity. Inflation remains a concern for the markets as well, given record commodity prices and its recent elevated level. Although inflation is generally a lagging indicator and should ease with slowing economic growth, it deserves attention given its negative impact and the notion that inflation may limit the Fed’s options to further stimulate economic growth.

Although export growth has been strong, helping to offset domestic weakness, and corporate balance sheets are generally healthy, something that has provided support for equity prices, markets are likely to tread cautiously. Nevertheless, we remain committed to our fundamental investment approach in our effort to find opportunities that we believe represent an attractive risk/reward profile. As always, we will continue to emphasize bottom-up company analysis as our primary tool in our quest to add value for shareholders.

Thank you for your investment in Janus Venture Fund.

Returns include reinvestment of dividends from net investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

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 unmanaged and are not available for direct investment; therefore their performance does not reflect the expenses associated with the active management of an actual portfolio.

	Beginning Account Value		Ending Account Value		Expenses Paid During Period
Expense Example	(11/1/07)		(4/30/08)		(11/1/07-4/30/08)†
Actual	$	1,000.00	$	754.50	$	3.84
Hypothetical (5% return before expenses)	$	1,000.00	$	1,020.49	$	4.42

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.

Andy Acker

portfolio manager

Introduction

April 30, 2008 marked the completion of my first year as portfolio manager of the Janus Global Life Sciences Fund. I had worked closely with former manager Tom Malley over the previous eight years. While Tom’s leadership will be missed, I am fortunate to be working with an outstanding team of six dedicated health care analysts (combined we have over 65 years of professional investment experience). Their considerable efforts and strong stock picking allowed for a smooth transition.

Performance Overview

The Janus Global Life Sciences Fund returned 2.42% for the twelve-month period and (6.88)% for the six-month period, ended April 30, 2008. This performance compared favorably to the (4.68)% twelve-month return and (9.64)% six-month return for the S&P 500^® Index (the Fund’s primary benchmark), and significantly outperformed the (10.47)% twelve-month return and (9.75)% six-month return for the MSCI¹ World Health Care Index^SM (the Fund’s secondary benchmark). The 12.89% outperformance versus the health care benchmark over the past year helped place the Fund in the top 4% of its Lipper peer group.

Investment Strategy

The Fund seeks to uncover opportunities that span the life sciences spectrum, including stocks in the biotechnology, pharmaceuticals, health care services, and medical technology arenas. Our bottom-up fundamental approach utilizes extensive proprietary research in an effort to discover the best investment ideas across the globe.

Portfolio Composition

The portfolio includes companies that can be categorized into three conceptual groups: core growth, emerging growth and opportunistic investments. In general, about half of the portfolio is invested in core growth holdings (companies with dominant franchises that generate strong, consistent free cash flow). Emerging growth companies (those with new products that we believe can drive earnings acceleration) represent 20-30% of the portfolio. The remaining weighting consists of opportunistic investments, exemplified by companies suffering from what we feel are short-term market misperceptions that should resolve over time.

Stocks That Aided Returns

Unlike many health care sector funds, the Janus Global Life Sciences Fund has a broad mandate which includes the ability to invest in the agricultural industry. The agricultural sector is experiencing tremendous growth, driven by strong demand from emerging markets and tight global supplies.

The Fund’s top contributor for the period was K+S A.G., the largest producer of potash (a key fertilizer ingredient) in Europe. After 20 years of stagnation, potash prices have accelerated dramatically (up over 300% over the past two years), driven by strong demand for improved crop production yields. Given the company’s relatively fixed cost base, rising prices have led to a disproportionate profit gain for K+S, and an attractive return on our investment (up over 100% during the six-month period).

Syngenta A.G., the Swiss agrichemical giant, was another top contributor for the Fund during the period. The company recently reported double-digit revenue growth and continued margin expansion. Beyond pesticides and herbicides, Syngenta is one of the world leaders in developing biotechnology based seeds to improve agricultural productivity, a technology which could help alleviate the supply/demand imbalances for food currently facing the world.

68  Janus Growth Funds  April 30, 2008

In the biotechnology sector, United Therapeutics was a top contributor, benefiting from successful clinical trial results for a new inhaled formulation of key drug Remodulin. Inhaled Remodulin represents an advance for patients suffering from a severe disease called pulmonary hypertension. United Therapeutics represents a key theme of the Fund, investing in companies that we believe are addressing high unmet medical needs.

Stocks That Weighed on Returns

The largest detractor from Fund performance during the period was pharmaceutical firm Merck & Company. After several years of strong price appreciation, Merck’s stock was adversely impacted in early 2008 by a negative trial involving Vytorin, a key cholesterol drug marketed jointly with Schering-Plough (another Fund holding). This trial outcome (and the subsequent negative press coverage) led to a substantial decline in prescriptions and projected sales for the franchise. Despite this setback, we continue to like the long-term outlook for the company and added to the position.

Pharmaceutical company Shire was another weak performer due to the slower-than-expected launch of a new drug, Vyvanse, for the treatment of attention deficit hyperactivity disorder (ADHD). While the pace of this launch did not meet high expectations, Shire has a number of growing products in what we feel are attractive specialty markets with long patent lifecycles. We continue to like the long-term outlook for the company.

In the managed care sector, UnitedHealth Group detracted from returns during the period as the stock suffered from near-term earnings revisions and concerns about the upcoming presidential election cycle. We think the company should be able to correct some recent missteps and continue to believe the stock represents an attractive value.

Risk Management

The Fund experienced several setbacks in 2006, which prompted us to re-evaluate and further refine our investment process. In consultation with Janus’ head of risk management, Dan Scherman, we incorporated a value-at-risk (VAR) approach to further strengthen the Fund’s risk control framework. This approach focuses our attention on downside risk, especially that arising from binary events (such as clinical trial announcements or regulatory decisions) that can lead to significant share price volatility. In practice, this means the position size of any one holding is limited so that, in a worst-case scenario, the estimated adverse impact from a particular event should not exceed 1% of the Fund’s performance. We incorporated the VAR approach at the beginning of 2007 and are encouraged by the results so far.

Looking Ahead

We believe aging populations and technological advances will continue to support rapid health care spending growth across the world’s economies. We also see significant opportunities in emerging markets as rising standards of living in those regions should lead to increased health care expenditures.

The underperformance of health care stocks versus the broader indices over the last five years has created what we feel are compelling valuations within the sector. In addition, we think concerns about slowing economic growth should highlight the sector’s defensive qualities.

We have conviction in the names we own and are pleased with the Fund’s recent and long term performance. We continue to seek investments within life sciences that we feel represent the sector’s best opportunities.

Thank you for your continued investment in the Janus Global Life Sciences Fund.

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.

A 2% redemption fee may be imposed on shares held for 90 days or less. Performance shown does not reflect this redemption fee and, if reflected, performance would have been lower.

The fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2007. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.)

The Fund’s performance may be affected by risks that include those associated with 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 (“IPOs”) and derivatives. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

This Fund invests in certain industry groups, which may react similarly to market developments (resulting in greater price volatility), and may have significant exposure to foreign markets (which include risks such as currency fluctuation and political uncertainty).

Funds that invest in Real Estate Investment Trusts (REITs) may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: legal, political, liquidity and interest rate risks, a decline in the value of real estate, risks related to economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Fund invests in foreign REITs, the Fund may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

The use of short sales may cause the Fund to have higher expenses than those of other equity funds. Short sales are speculative transactions and involve special risks, including a greater reliance on the investment team’s ability to accurately anticipate the future value of a security. The Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s use of short sales in effect leverages the Fund’s portfolio. The Fund’s use of leverage may result in risks and can magnify the effect of any losses. There is no assurance that a leveraging strategy will be successful.

Returns include reinvestment of dividends from net investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

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.

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 unmanaged and are not available for direct investment; therefore their performance does not reflect the expenses associated with the active management of an actual portfolio.

See “Explanations of Charts, Tables and Financial Statements.”

Fund Expenses

The example below shows you the ongoing costs (in dollars) of investing in your Fund and allows you to compare these costs with those of other mutual funds. Please refer to the section Useful Information About Your Fund Report for a detailed explanation of the information presented in this chart.

Janus Growth Funds  April 30, 2008  75

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.

Barney Wilson

portfolio manager

Performance Overview

During the six months ended April 30, 2008, Janus Global Technology Fund returned (12.26)%. By comparison, the Fund’s benchmarks, the Morgan Stanley Capital International (MSCI) World Information Technology Index^SM and the S&P 500^® Index returned (14.29)% and (9.64)%, respectively.

Investment Strategy

Janus Global Technology Fund’s objective is to seek long-term growth of capital. I work closely with the Janus analysts covering technology and technology-related companies to identify high quality and innovative technology companies that are growing earnings and cash flow in excess of market expectations. While investing in the information technology sector can be more volatile than a broader market index, I believe the sector can provide an excellent opportunity for attractive investment returns if one can tolerate the volatility.

Three things are at the core of the Fund’s investment and portfolio construction philosophy: fundamental research, valuation analysis and diversification. First, in the intensive research that is a hallmark of Janus, we seek out the customers, competitors and suppliers of a company to develop our view of the future fundamental performance of that company. We try to anticipate material changes in industries and to understand which companies are going to win on a multi-year basis in the product marketplace and why. Second, in conducting our valuation analysis, we focus foremost on the value of the future cash flows of the company. Third, when constructing the Fund, I deliberately seek to control risk by diversifying across multiple dimensions, such as subsectors, geographies, market capitalizations and valuation ranges.

To anticipate changes in foreign currency, I may hedge a portion of the Fund’s foreign currency exposure. Forward foreign currency exchange contracts may be used to buy and sell currencies in order to fix a price for foreign securities. Please see the “Notes to Financial Statements” for a discussion of derivatives used by the Fund.

Contributors to Fund Performance

One investment theme in the Fund is alternative energy, which represents only a small part of today’s energy generation. As the use grows, however, technology companies that provide competitive and effective solutions should benefit. Two of the strongest contributors for the period are involved in solar energy.

First Solar produces solar cells using thin-film technology, a specialized approach to solar energy production. The company continued to report strong results and growth as it ramped up its production. JA Solar Holdings Company also produces solar cells, although with a different technology. These cells, using silicon, are larger but more efficient than thin-film technology. It is a more traditional technology, but I believe JA Solar has advantages over competitors, such as lower production costs and access to refined silicon, which has been in short supply.

Detractors from Performance

Telecommunication services company SAVVIS was the largest detractor during the period, as the company reported several disappointing quarters. While the company has had inconsistent execution, our research indicates that SAAVIS is still well-positioned. The company, which runs data centers for hosting and optimizing web pages and content delivery, has been a predictable, recurring revenue business with little economic sensitivity. It has benefited from pricing power and a strong secular backdrop.

ARM Holdings, a U.K. electronics company, fell after reporting mixed results during the period. The company, which generates licensing revenue partly from its designs for integrated circuits in smart phones, was hurt by lower-than-expected revenues and continued weakness in the U.S. dollar. I believe the short-term issues mask the long-term opportunities, as smart phones will likely come to represent a greater share of the wireless handset market, providing ARM with the opportunity to sell chip designs with higher royalties.

Looking Ahead

I focus on anticipating change, trying to determine which companies are going to win on a multi-year basis in the product marketplace, and on finding companies where I feel the price of the stock is below the value of the cash flows of the company. My goal will continue to be to leverage the strong, grassroots research foundation of Janus to uncover what I believe are the best investment opportunities for our shareholders.

Thank you for your investment in Janus Global Technology Fund.

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.

A 2% redemption fee may be imposed on shares held for 90 days or less. Performance shown does not reflect this redemption fee and, if reflected, performance would have been lower.

The fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2007. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.)

Janus Global Technology Fund (unaudited)

The Fund’s performance may be affected by risks that include those associated with 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 (“IPOs”) and derivatives. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the Fund, and therefore the Fund’s performance, may decline in response to such risks.

This Fund may at times have significant exposure to certain industry groups, which may react similarly to market developments (resulting in greater price volatility). The Fund also may have significant exposure to foreign markets (which include risks such as currency fluctuation and political uncertainty).

The use of short sales may cause the Fund to have higher expenses than those of other equity funds. Short sales are speculative transactions and involve special risks, including a greater reliance on the investment team’s ability to accurately anticipate the future value of a security. The Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s use of short sales in effect leverages the Fund’s portfolio. The Fund’s use of leverage may result in risks and can magnify the effect of any losses. There is no assurance that a leveraging strategy will be successful.

Returns include reinvestment of dividends from net investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

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.

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 unmanaged and are not available for direct investment; therefore their performance does not reflect the expenses associated with the active management of an actual portfolio.

See “Explanations of Charts, Tables and Financial Statements.”

* The Fund’s inception date – December 31, 1998

Fund Expenses

The example below shows you the ongoing costs (in dollars) of investing in your Fund and allows you to compare these costs with those of other mutual funds. Please refer to the section Useful Information About Your Fund Report for a detailed explanation of the information presented in this chart.

	Beginning Account Value		Ending Account Value		Expenses Paid During Period
Expense Example	(11/1/07)		(4/30/08)		(11/1/07-4/30/08)†
Actual	$	1,000.00	$	877.40	$	4.62
Hypothetical (5% return before expenses)	$	1,000.00	$	1,019.94	$	4.97

† Expenses are equal to the annualized expense ratio of 0.99%, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the one-half year period).

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, 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 is 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 twenty-nine funds. The Funds invest primarily in equity securities. Each Fund 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. Circumstances in which fair value pricing may be utilized include, but are not limited to: (i) when significant events occur which may affect the securities of a single issuer, such as mergers, bankruptcies, or significant issuer-specific developments; (ii) when significant events occur which may affect an entire market, such as natural disasters or significant governmental actions; and (iii) when non-significant events occur such as markets closing early or not opening, security trading halts, or pricing of non-valued securities and restricted or non-public securities. 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. Dividends from foreign securities may be subject to withholding taxes in foreign 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 Fund 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. 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 if time permits. 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, time deposits, repurchase agreements, money market mutual funds or other money market accounts, or such other collateral permitted by the

Notes to Financial Statements (unaudited) (continued)

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.

Dresdner Bank AG (the “Lending Agent”) may also invest the cash collateral in the Allianz Dresdner Daily Asset Fund 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.

As of April 30, 2008, the Funds had on loan securities valued as indicated:

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 loaned 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 the Lending Agent. The Lending Agent may retain a portion of the interest earned on the cash collateral invested. The cash collateral invested by the Lending Agent is disclosed in the Schedule of Investments (if applicable). The lending fees and the Funds’ portion of the interest income earned on cash collateral are included on the Statement of Operations (if applicable).

Interfund Lending

Pursuant to an exemptive order received from the SEC, the Funds may be party to interfund lending agreements between the Funds and other Janus Capital-sponsored mutual funds, which permit 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 the 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 Funds may enter into forward currency contracts in order to reduce exposure to changes in foreign currency exchange rates on 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 investment and 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

102  Janus Growth Funds  April 30, 2008

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.

Futures Contracts

The Funds may enter into futures contracts to gain exposure to the stock market pending investment of cash balances or to meet liquidity needs. The Funds may also 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 values 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 as “Net realized gain/(loss) from futures contracts” 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.

Swaps

The Funds may enter into swap agreements to hedge exposure to interest rates and credit risk or for investment purposes. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. Swap contracts are reported as an asset and liability on the Statement of Assets and Liabilities. Realized gains and losses are reported in “Net realized gain/(loss) from swap contracts” on the Statement of Operations (if applicable).

Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the swap contract. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Funds, and/or the termination value. Therefore, the Funds consider the creditworthiness of each counterparty to a swap contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities.

Options Contracts

The Funds may purchase or write put and call options on futures contracts and on portfolio securities for hedging purposes or as a substitute for an investment. The Funds may also purchase or write put and call options on foreign currencies in a manner similar to that in which futures or forward contracts on foreign currencies will be utilized. The Funds may also invest in Long-Term Equity Anticipation Securities (LEAPS), which are long-term option contracts that can be maintained for a period of up to three years. The Funds generally invest in options to hedge against adverse movements in the value of portfolio holdings.

When an option is written, the 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 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 Funds could result in the Funds 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 are adjusted by the amount of premium received or paid.

The Funds may also purchase and write exchange-listed and over-the-counter put and call options on domestic securities indices, and on foreign securities indices listed on domestic and foreign securities exchanges. Options on securities indices are similar to options on securities except that (1) the expiration cycles of securities index options are monthly, while those of securities options are currently quarterly, and (2) the delivery requirements are different. Instead of giving the right to take or make delivery of securities at a specified price, an option on a securities index gives the holder the right to receive a cash “exercise settlement amount” equal to (a) the amount, if any, by which the fixed exercise price of the option exceeds (in the case of a put) or is less than (in the case of a call) the closing value of the underlying index on the date of exercise, multiplied by (b) a fixed “index multiplier.” Receipt of this cash amount will depend upon the closing level of the securities index upon which the option is based being greater than, in the case of a call, or less than, in the case of a put, the exercise price of the index and the exercise price of the option times a specified multiple. The writer of the option is obligated, in return for the premium received, to make delivery of this amount.

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 as “Options written at value” (if applicable).

Realized gains and losses are reported as “Net realized gain/(loss) from options contracts” on the Statement of Operations

(if applicable). The Funds recognized realized gains/(losses) from written options contracts during the six-month period ended April 30, 2008 as indicated in the table below:

Fund	Gains/(Losses)
Growth
Janus Fund	$	1,048,806
Janus Orion Fund		9,269,563
Specialty Growth
Janus Global Technology Fund	($	1,498,835)

The risk in writing call options is that the Funds give up the opportunity for profit if the market price of the security increases and the option is exercised. The risk in writing put options is that the Funds may incur a loss if the market price of the security decreases and the option is exercised. The risk in buying options is that the 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 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 Funds’ 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 the Funds may recognize due to written call options.

Written option activity for the six-month period ended April 30, 2008 is indicated in the tables below:

Short Sales

The Funds may engage in “short sales against the box.” Short sales against the box involve either selling short a security that the Funds own, or selling short a security that the Funds have the right to obtain, for delivery at a specified date in the future. The Funds may enter into short sales against the box to hedge against anticipated declines in the market price of portfolio securities. The Funds do not deliver from their portfolios the securities sold short and do not immediately receive the

104  Janus Growth Funds  April 30, 2008

proceeds of the short sale. The Funds borrow the securities sold short and receive proceeds from the short sale only when they deliver the securities to the lender. If the value of the securities sold short increases prior to the scheduled delivery date, the Funds lose the opportunity to participate in the gain.

The Funds may also engage in other short sales. The Funds may engage in short sales when the portfolio managers and/or investment personnel anticipate that a security’s market purchase price will be less than its borrowing price. To complete the transaction, the Funds must borrow the security to deliver it to the purchaser and buy that same security in the market to return it to the lender. The total market value of all of a Fund’s short sales positions, other than against the box, will not exceed 10% of its net assets. Although the potential for gain as a result of a short sale is limited to the price at which the Fund sold the security short less the cost of borrowing the security, the 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 to the size of any loss that the Fund may recognize upon termination of a short sale. Short sales held by the Funds are fully collateralized by other securities, which are denoted in the accompanying Schedule of Investments (if applicable).

Foreign Currency Translations

The Funds do not isolate that portion of the results of operations resulting from the effect of 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 of investments and foreign currency translations arises 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 foreign 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.

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 Funds may hold liquid assets as collateral with the Funds’ custodian sufficient to cover the purchase price.

Exchange-Traded Funds

The Funds may invest in exchange-traded funds, which are index-based investment companies that hold substantially all of their assets in securities representing their specific index. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operations.

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 non-registered 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.

Restricted Cash

As of April 30, 2008, Janus Orion Fund and Janus Research Fund had restricted cash in the amount of $8,392,000 and $2,970,000, respectively. The restricted cash represents funds in relation to options contracts invested by the Funds as of April 30, 2008. The restricted cash is held at the Funds’ custodian, State Street Bank and Trust Company. The carrying value of the restricted cash approximates fair value.

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.

Janus Growth Funds  April 30, 2008  105

Notes to Financial Statements (unaudited) (continued)

Restricted Security Transactions

Restricted securities held by the Funds may not be sold except in exempt transactions or in a public offering registered under the Securities Act of 1933, as amended. 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 the Funds 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

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

The Funds may make certain investments in real estate investment trusts (“REITs”) which pay dividends to their shareholders based upon funds available from operations. It is quite common for these dividends to exceed the REIT’s taxable earnings and profits, resulting in the excess portion of such dividends being designated as a return of capital. If the Funds distribute such amounts, such distributions could constitute a return of capital to shareholders for federal income tax purposes.

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.

The Funds adopted the provisions of Financial Accounting Standards Board (“FASB”) Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes on April 30, 2008. FIN 48 requires an evaluation of tax positions taken (or expected to be taken) in the course of preparing a Fund’s tax return to determine whether these positions meet a “more-likely-than-not” standard that based on the technical merits have a more than fifty percent likelihood of being sustained by a taxing authority upon examination. A tax position that meets the “more-likely-than-not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations.

FIN 48 requires management of the Funds to analyze all open tax years, fiscal years 2003-2006 as defined by Statute of Limitations, for all major jurisdictions, including federal tax authorities and certain state tax authorities. As of and during the six-month period ended April 30, 2008, the Funds did not have a liability for any unrecognized tax benefits. The Funds have no examination in progress and are not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

New Accounting Pronouncements

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS No. 157”), which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS No. 157 does not require new fair value measurements, but is applied to the extent that other accounting pronouncements require or permit fair value measurements. SFAS No. 157 emphasizes that fair value is a market-based measurement that should be determined based on the assumptions that market participants would use in pricing an asset or liability. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. Management does not believe the adoption of SFAS No. 157 will impact the financial statement amounts; however, the Funds will be required to disclose the extent to which fair value is used to measure assets and liabilities and the inputs used to develop the measurements.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS No. 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. SFAS No. 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. SFAS No. 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. Management does not believe the adoption of SFAS No. 159 will impact the financial statement amounts.

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities”

106  Janus Growth Funds  April 30, 2008

(“SFAS No. 161”), which requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. SFAS No. 161 is effective for financial statements issued for fiscal years beginning after November 15, 2008, and interim periods within those fiscal years. Management is in the process of evaluating the impact of SFAS No. 161 on the Funds’ financial statement disclosures.

2. Investment Advisory Agreements and Other Transactions With Affiliates

The Funds pay 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	Advisory Fee %
Growth
Janus Fund		0.64%
Janus Enterprise Fund		0.64%
Janus Orion Fund		0.64%
Janus Research Fund		0.64%
Janus Triton Fund		0.64%
Janus Twenty Fund		0.64%
Janus Venture Fund		0.64%
Specialty Growth
Janus Global Life Sciences Fund		0.64%
Janus Global Technology Fund		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 table above. The performance adjustment either increases or decreases the base fee depending on how well the Fund has performed relative to its benchmark, as shown in the following table:

Fund	Benchmark Index
Janus Research Fund		Russell 1000® Growth Index

Any performance adjustment for Janus Research Fund commenced on February 1, 2007, prior to which only the base rate fee applied. 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 the 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. 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 performance relative 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 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.

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 the Fund relative to the record of the Fund’s benchmark index and future changes to the size of the Fund.

The Fund’s prospectus and statement of additional information contain 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. During the six-month period ended April 30, 2008, the Fund recorded the following Performance Adjustment as indicated in the table below:

	Performance
Fund	Fee
Janus Research Fund	$	3,103,459

Until at least March 1, 2009, 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 the Fund’s normal operating expenses in any fiscal year, including the investment advisory fee, but excluding

Janus Growth Funds  April 30, 2008  107

Notes to Financial Statements (unaudited) (continued)

brokerage commissions, interest, dividends, taxes and extraordinary expenses (including, but not limited to, acquired fund fees and 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.

The Funds’ expenses may be reduced by expense offsets from an unaffiliated custodian and/or transfer agent. Such credits or offsets are included in “Expense and Fee Offset” 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.

Each Fund pays Janus Services LLC (“Janus Services”), a wholly-owned subsidiary of Janus Capital and the Funds’ transfer agent, 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, 2008, 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, 2008, Janus Capital assumed $16,904 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 the Pending Legal Matters. 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 the Portfolios that commenced operations after July 31, 2004. As a result, no fees were allocated to Janus Triton Fund. Additionally, all future non-recurring costs will be allocated to the Portfolios based on 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 Board of Trustees has adopted a deferred compensation plan (the “Deferred 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.

108  Janus Growth Funds  April 30, 2008

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 are credited to the account. The fluctuation of the account balance is recorded by the Funds as unrealized appreciation/(depreciation) and is shown as of April 30, 2008 on the Statement of Assets and Liabilities as an asset, “Non-interested Trustees’ deferred compensation,” and a liability, “Non-interested Trustees’ deferred compensation fees.” Additionally, the recorded unrealized appreciation/(depreciation) is included in “Unrealized net appreciation/(depreciation) of investments, foreign currency translations and non-interested Trustees’ deferred compensation” on the Statement of Assets and Liabilities. Deferred compensation expenses for the six-month period ended April 30, 2008 are included in “Non-interested Trustees’ fees and expenses” on the Statement of Operations. Trustees are allowed to change their designation of mutual funds from time to time. Amounts will be deferred until distributed in accordance with the Deferred Plan. No deferred fees were paid to any Trustee under the Deferred Plan during the six-month period ended April 30, 2008.

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 Trust. Total compensation of $39,907 was paid by the Trust during the six-month period ended April 30, 2008. Each Fund’s portion is reported as part of “Other Expenses” on the Statement of Operations.

A 2.00% redemption fee may be imposed on shares of Janus Global Life Sciences Fund and Janus Global Technology Fund 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 the Funds for the six-month period ended April 30, 2008 are indicated in the table below:

Fund	Redemption Fee
Janus Global Life Sciences Fund	$	68,000
Janus Global Technology Fund	$	97,005

The Funds may invest in money market funds, including funds managed by Janus Capital. During the six-month period ended April 30, 2008, the following Funds recorded distributions from affiliated investment companies as affiliated dividend income, and had the following affiliated purchases and sales:

4.  Federal Income Tax

Income and capital gains distributions are determined in accordance with income tax regulations that may differ from accounting principles generally accepted in the United States of America. These differences are due to differing treatments for items such as net short-term gains, deferral of wash sale losses, foreign currency transactions, net investment losses and capital loss carryovers.

The Funds have elected to treat gains and losses on forward foreign currency contracts as capital gains and losses. Other foreign currency gains and losses on debt instruments are treated as ordinary income for federal income tax purposes pursuant to Section 988 of the Internal Revenue Code.

The aggregate cost of investments and the composition of unrealized appreciation and depreciation of investment securities for federal income tax purposes as of April 30, 2008 are noted below.

Unrealized appreciation and unrealized depreciation in the table below exclude appreciation/depreciation on foreign currency translations. The primary difference between book and tax appreciation or depreciation of investments are wash sale loss deferrals and passive foreign investment companies.

6.  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 actions: Janus Investment

112  Janus Growth Funds  April 30, 2008

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. The appeal is still pending and argument in the matter was held in December 2007. 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. However, in June 2007, Plaintiffs appealed that dismissal to the United States Court of Appeals for the Fourth Circuit. That appeal is currently pending.

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 status conference was held on June 28, 2007, during which the parties were ordered to submit their proposed scheduling order. To date, no scheduling order has been entered in the case. In addition to the pending Motion to Discharge Order to Show Cause, 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.

During 2007, two lawsuits were filed against Janus Management Holdings Corporation (“Janus Holdings”), an affiliate of JCGI, by former Janus portfolio managers, alleging that Janus Holdings unilaterally implemented certain changes to compensation in violation of prior agreements. These complaints allege some or all of the following claims: (1) breach of contract; (2) willful and wanton breach of contract; (3) breach of good faith and fair dealing; and (4) estoppel. Janus Holdings filed Answers to these complaints denying any liability for these claims and intends to vigorously defend against the allegations.

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, none of whom has ever been affiliated with Janus Capital (“Independent Trustees”), oversee the management of each Fund 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 Fund, 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 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 with management to consider the agreements, and also met separately in executive session with their independent legal counsel and their independent fee consultant.

At a meeting held on December 14, 2007, based on their evaluation of the information provided by Janus Capital, the subadvisers and the independent fee consultant, as well as other information, the Trustees determined that the overall arrangements between each Fund and Janus Capital and each subadviser, as applicable, 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 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, 2008 through February 1, 2009 (January 1, 2008 through January 1, 2009 for INTECH Risk-Managed Stock Fund and Janus Global Research Fund), subject to earlier termination as provided for 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, the knowledge of 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 and/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 those 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

114  Janus Growth Funds  April 30, 2008

appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract well-qualified personnel.

Performance of the Funds

The Trustees considered the investment performance 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 many 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 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, 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.

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 fee rates for Funds having a similar strategy, the Trustees noted that, under the terms of 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, the Trustees 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.

The Trustees reviewed information on the profitability to Janus Capital and its affiliates of their relationships with each Fund, as well as an explanation of the methodology used in allocating various expenses of Janus Capital and its affiliates among the Funds and other clients. They 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 receives adequate incentives to manage the Funds effectively. They 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 adviser, 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 payable by Janus Capital or the Funds to the subadvisers of subadvised Funds, were reasonable in relation to the nature, extent 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 subadvisers charge to other clients. They 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, those Funds benefited from having advisory fee rates that remained constant rather than increasing as assets declined. In addition, performance fee structures have been

Additional Information (unaudited) (continued)

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. They also considered Janus Capital’s past and proposed use of commissions paid by Funds on their portfolio brokerage transactions to obtain proprietary and third-party research products and services benefiting those Funds and/or other clients of Janus Capital. The Trustees concluded that Janus Capital’s use of “soft” commission dollars of a Fund to obtain proprietary and third-party 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 also concluded that Janus Capital benefits from the receipt of proprietary and third-party 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, all of whom are 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 (from inception) 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 dividends and distributions, 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 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, 2007. 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 written options contracts follows each Fund’s Schedule of Investments (if applicable). Written options 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 will 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 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 and expense reimbursements, if any, are also shown.

The last section lists the increase or decrease in the value of securities held in the Funds. The 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 Funds’ 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 will 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 withdrawals via redemptions. “Redemption Fees” (if applicable) refers to the fee paid to the Funds for shares held for 90 days 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 each Fund’s net asset value (“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 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 frequency of dividend payments 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 the offset and the net expenses. The

118  Janus Growth Funds  April 30, 2008

expense ratios listed in the Financial Highlights reflect total expenses prior to any expense offset (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 size asset 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.

Janus provides access to a wide range of investment disciplines.

Asset Allocation

Janus asset allocation portfolios 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.

Co-Chief Investment Officers’ Letter to the Shareholders

Jonathan Coleman

Co-Chief Investment Officer

Gibson Smith

Co-Chief Investment Officer

Dear Shareholders,

Challenging economic conditions have been the dominant theme for the financial markets over the past several months. Despite recent volatility, our investment team has maintained a relentless focus on our fundamental, bottom-up research process and has continued to discover compelling investment opportunities for our shareholders.

Major Market Themes

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above their mid-March lows, stocks were broadly lower over the six months ended April 30, 2008. The Russell 1000^® Index declined 9.54%, the Russell 2000^® Index was down 12.92% and the Morgan Stanley Capital International (MSCI) All Country World Index^SM gave up 9.47% during the period. Fixed-income markets proved to be volatile over the period with the Lehman Brothers Aggregate Bond Index up 4.08% and the Lehman Brothers High-Yield Bond Index lost 0.74% over the period.

Additional write-offs related to the loose lending practices over the previous 36 months, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Uncertain market conditions resulted in interest rates hitting five-year lows with the 10-Year Treasury Note touching 3.33%. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the funding and credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept, allowed for broker/dealers to borrow directly from the Fed and played an instrumental role in JP Morgan Chase’s purchase of near-defunct Bear Stearns. All of these moves were vitally important toward stabilizing the financial system while allowing for the recovery process to continue. By the end, the Fed had lowered its target interest rate from 4.50% to 2.00% during the period.

Following the March lows, the equity market’s rally at the end of the six-month period can be attributed to the moves by the Fed and, in part, to improving sentiment as investors began to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs continued to weigh on the market.

Performance Notables

For the one-year period ended April 30, 2008, 77% of Janus’ retail funds ranked within Lipper’s top two quartiles, based upon total returns. The results were even stronger over longer time periods as 87% of our retail funds achieved first- or second-quartile Lipper rankings over three years and 86% ranked in Lipper’s top two quartiles over five years. Furthermore, 78.3% of our retail funds had a 4- or 5-star overall Morningstar Rating^tm as of April 30, 2008, well ahead of the 32.5% of funds for which Morningstar awards 4- or 5-stars in each category. (See complete Lipper rankings on page 3 and complete Morningstar Ratings^tm on page 4).

Investment Team Update

We continue to enhance the breadth of our global stock coverage and work tirelessly to generate solid investment insights in an attempt to deliver superior investment performance. Our hands-on research approach is critical to our stock selection process. As such, the Janus equity research team traveled over 2.9 million miles in 2007 investigating potential stock and bond picks worldwide. This year, we plan to embark on a multi-year strategy to locate certain investment personnel closer to the companies that they research as an important first step in building out our global footprint from a research standpoint.

While our objective is to develop a research edge and invest with conviction in our funds, we seek to do so in a disciplined and thoughtful way by clearly understanding and managing risk in our portfolios. Dan Scherman, Director of Risk and Trading, works continually with our investment management

team to ensure that portfolio risks are intentional and calculated. We believe this analysis is both timely and critical as we navigate today’s challenging markets.

Conclusion

As we look back over the past six months, we are relieved that signs of stabilization appeared in the financial markets as the period came to a close. However, we recognize that there are still significant challenges ahead. Increasing risk aversion has resulted in a significant contraction of credit availability for both consumers and corporations. The tightening of credit, along with declining real estate prices, rising energy prices and a climbing unemployment rate may all create significant economic headwinds in the near future. While unsettling, we believe this is a natural and necessary process of recovery from the excessive risk-taking and loose lending standards that developed over the previous several years in many areas of the credit markets. We feel that the environment will improve as the healing process progresses.

So, as we look ahead, we are paying very close attention to the outlook for the global economy, with a keen focus on slowing growth in the United States and the growth rates of the emerging economies around the globe. As these emerging economies become more prosperous, they may be able to move from economies based exclusively on exports fueling their growth to more balanced models emphasizing both exports and internal consumption of the goods they produce. Over a longer period of time, we believe this creates more stability in the global economy. We are also watching rising energy and commodity prices and their impact on inflationary expectations and the absolute level of interest rates. In addition to interest rates, we are focused on the outlook for the housing market and the implications of changes in home prices on the underlying health of the financial system, believing that the recapitalization of the banking and brokerage sectors is a vitally important element of the healing process.

While market volatility is undoubtedly challenging, it can also create an environment that can result in incredibly compelling investment opportunities. Our top priority is to remain committed to our process of in-depth fundamental research, which has been at the core of our investment process since Janus’ inception in 1969. With this singular focus we strive to deliver consistent long-term results for our shareholders.

Thank you for your continued investment in Janus funds.

Sincerely,

Data presented reflects past performance, which is no guarantee of future results.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating^TM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of the funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variation in the distribution percentages.)

Useful Information About Your Fund Report

Management Commentaries

The Management Commentaries in this report include valuable insight from each of 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, 2008. As the investing environment changes, so could the managers’ 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, 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 upon an investment of $1,000 invested at the beginning of the period and held for the six-month period from November 1, 2007 to April 30, 2008.

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 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.

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, 2009. 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.

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 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 Balanced Fund (unaudited) Ticker: JABAX

Fund Snapshot

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

Marc Pinto

co-portfolio manager

Gibson Smith

co-portfolio manager

Performance Overview

Janus Balanced Fund returned (1.72)% for the six-month period ended April 30, 2008, compared with a (3.50)% 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 (9.64)% and 4.14%, respectively.

Economic Overview

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well off their mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008. Meanwhile, interest rates trended lower for much of the period as investors looked to less risky U.S. Treasuries during the growing uncertainty. The yield curve ended the period with a much steeper slope as the yield on the 3-month Treasury bill fell by 253 basis points (bps) to 1.38% and the 10-year Treasury yield declined 74 bps to 3.73%.

Additional write-offs related to the loose lending practices over the previous 36 months, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept and played an instrumental role in JP Morgan Chase’s purchase of Bear Stearns. By the end, the Fed had lowered its target interest rate from 4.50% to 2.00% during the period.

Overall, mid-cap stocks held up better than large- and small-cap stocks, while growth outperformed value stocks. All sectors declined with the exception of energy, which turned in a gain for the six-month period amid record crude oil prices. Meanwhile, financials were the worst performing group, suffering from turmoil in the credit markets and larger-than-expected subprime-related write-downs. Information technology was also among the weakest performers while defensive sectors, like consumer staples, posted small declines. Within the bond market, U.S. Treasuries outperformed corporate debt as the spreads between the yield on corporate bonds and mortgage-backed securities to equivalent U.S. Treasuries widened, or rose to their highest level. High-yield bonds posted modest declines during the period, with the corporate credit sector among the weakest performing fixed-income groups. Improving credit market conditions, however, helped spreads narrow late in the period and finish off their widest levels.

Following the March lows, the equity market’s rally at the end of the period can be attributed in part to improving sentiment as investors began to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs continued to weigh on the market.

Materials Holdings Benefited Fund Performance

The Fund’s outperformance can be attributed primarily to strong, individual stock selection within the materials sector. The top contributor to performance was fertilizer company Potash Corporation of Saskatchewan, where price increases and a solid market position continued to drive returns. We believe the business remains intact and the secular tailwinds of rising agriculture demand, limited potash supply and pricing power are firmly in place. We also believe the company’s announced price increases provide for revenue predictability. However, following a prolonged period of strong performance we trimmed the position in favor of what we believe to be better risk/reward opportunities.

Also within the materials sector, Swiss-based Syngenta, a leader in crop protection, reported strong results for the period driven by demand in Latin America. We believe

6  Janus Core, Risk-Managed and Value Funds  April 30, 2008

(unaudited)

Syngenta should soon see results from its internally developed seed products, eliminating the royalty cost the company has been paying to Monsanto. During the six-month period, we trimmed the position but maintain the view that Syngenta should continue to benefit from the strong secular tailwinds in agriculture and its position in the industry.

Select Financials and Information Technology Stocks Detracted from Results

Student loan provider SLM, formerly “Sallie Mae” declined after the deal to take it private was called off. Investors were concerned that SLM’s earnings outlook would be revised downward as its credit costs increased. Given that potential earnings risk and uncertainty about future credit conditions, we exited the position.

In the information technology sector data storage company, EMC struggled as VMware (of which EMC owns 80%) offered conservative guidance. Longer term, we believe VMware’s competitive position looks to be solid. That, coupled with the fact EMC’s core data storage business has been performing well led us to maintain our position.

Fixed-Income Investments Provided Positive Results

The strongest contribution to returns in the fixed-income portion of the Fund came from our overweight position in U.S. Treasuries. Our higher quality bias protected us as credit and concerns in the mortgage market continued to drive risk premiums wider and Treasury yields lower during the period. We held a nearly zero weighting in mortgage-backed pass-through securities at the end of the period, as we believed concerns about future volatility in the sector supported a cautious stance, which was also evident in our overweight position in highest-quality government securities. Within our credit allocation, both the overall underweight and security selection boosted returns. In terms of detractors, our underweight exposure to agency/government sponsored bonds weighed on relative returns. We are focused on best of breed investment grade companies and seek to select out-of-benchmark exposure to high-yield names with strong free cash flow and asset-heavy balance sheets identified through intensive fundamental credit research.

Outlook

Looking ahead, we will be paying close attention to the employment picture, the availability of credit and consumer confidence, among other things. Should the labor market continue to soften amid continued weakness in the housing market, further slowing in consumer spending is likely. While the government stimulus checks could provide a temporary boost, the current de-leveraging of the U.S. economy could take time to complete, possibly lessening the potential for a sharp rebound in economic activity. Inflation remains a concern for the markets as well, given record commodity prices and its recent elevated level. Although inflation is generally a lagging indicator and should ease with slowing economic growth, it deserves attention given its negative impact and the notion that inflation may limit the Fed’s options to further stimulate economic growth.

The housing market could be the core problem for the U.S. economy, given its ties to interest rates and credit markets. If the end-of-period uptrend in long-term interest rates continues and the spreads between mortgage-backed securities fail to narrow, or even widen, further weakness in housing could result, slowing the healing process within the financial system. Although export growth has been strong, helping to offset domestic weakness, and corporate balance sheets are generally healthy, markets are likely to tread cautiously. We remain committed to our fundamental investment approach in our effort to find opportunities that we believe represent an attractive risk/reward profile. As always, we will continue to emphasize bottom-up company analysis as our primary tool in our quest to add value for shareholders.

Thank you for investing in Janus Balanced Fund.

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 fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2007. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.) 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.

10  Janus Core, Risk-Managed and Value Funds  April 30, 2008

(unaudited)

The Fund’s performance may be affected by risks that include those associated with non-investment grade debt securities, 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 (“IPOs”) and derivatives. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and other details.

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.

Returns include reinvestment of dividends from net investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

September 3, 1992 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.

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 unmanaged and are not available for direct investment; therefore their performance does not reflect the expenses associated with the active management of an actual portfolio.

See “Explanations of Charts, Tables and Financial Statements.”

* The Fund’s inception date – September 1, 1992

Fund Expenses

The example below shows you the ongoing costs (in dollars) of investing in your Fund and allows you to compare these costs with those of other mutual funds. Please refer to the section Useful Information About Your Fund Report for a detailed explanation of the information presented in this chart.

	Beginning Account Value		Ending Account Value		Expenses Paid During Period
Expense Example	(11/1/07)		(4/30/08)		(11/1/07-4/30/08)†
Actual	$	1,000.00	$	982.80	$	3.85
Hypothetical (5% return before expenses)	$	1,000.00	$	1,020.98	$	3.92

†Expenses are equal to the annualized expense ratio of 0.78%, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the one-half year period).

Janus Contrarian Fund (unaudited) Ticker: JSVAX

Fund Snapshot

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

David Decker

portfolio manager

Performance Overview

Thank you for your continued investment in Janus Contrarian Fund. During the six-month period ended April 30, 2008, the Fund returned (7.78)%, modestly outperforming the (9.64)% return of the S&P 500^® Index, the Fund’s primary benchmark, and the (9.47)% return of the Morgan Stanley Capital International (MSCI) All Country World Index^SM, the Fund’s secondary benchmark.

Economic Overview

The credit crisis that began early in 2007 reached a pinnacle when the investment bank Bear Stearns nearly collapsed and was saved by the Federal Reserve (Fed) and JP Morgan Chase. Since that time, following a massive injection of liquidity by the Fed, the market staged a very powerful rally. This increasingly sanguine view of the economy and equity markets appears to be predicated on the assumption that with the credit crisis over, recent aggressive interest rate reductions will help power the U.S. consumer, thus allowing the U.S. economy to avoid a deep and long-lasting economic down-turn. While this may come to pass, I remain uncomfortable with the ability of the U.S. consumer to emerge quickly from their high degree of leverage, particularly given the impending impact of rising oil and commodity prices. Indeed, global inflation of commodities as well as highly restrictive debt markets will, in my view, provide a very powerful headwind to global economic growth as well as strong equity returns in the future.

Hedging

In the period I purchased put options on West Texas Intermediate (WTI) crude futures in order to hedge some of the crude exposure in the Petroleo Brasileiro (Petrobras) position. I am of the belief that Petrobras is an excellent long-term investment, irrespective of whether crude oil experiences a significant retrenchment. However, because I believe there is a risk of near-term weakness in the stock should crude weaken, I decided to hedge the risk to the investment of a significant pull-back in crude. Should crude continue its upward climb, the loss in the hedges should be largely offset by gains in Petrobras. Also, during the period I chose to buy index put options in an attempt to protect the Fund in the event of a severe downturn in the markets. An index put option increases in value when the underlying asset decreases in value. By buying index put options, I was endeavoring to partially offset the negative impact of any weakness in the broad market. (Please see “Notes to Financial Statements” for information about the hedging techniques used by the Fund.)

Stocks that Hurt Performance

It was not only a difficult environment for the global equity markets, it was a difficult environment for the Fund. While the Fund modestly outperformed the S&P 500^® Index during the period, I take no solace in generating negative returns, irrespective of the relative returns. Only absolute returns increase wealth, and as a very large investor in Janus Contrarian Fund, our interests are always aligned. Negative returns are to be expected over some periods in any long-term investment. However, performance during the period was marred by more than the natural volatility of the positions in the portfolio; it was marred by a few poor investment decisions.

The first important mistake was my investment in Tenaga Nasional Berhad, the largest power-generating company in Malaysia, which declined nearly 25% in the period. My investment thesis was predicated on the belief that it was a very attractively valued company with a highly shareholder-focused management team, operating in a market (Malaysia) with a high demand for power. One factor that made this a risky investment was that the government had yet to establish a fuel cost pass-through arrangement. Fuel cost pass-through is vital for a power company because if it cannot pass-through increased input costs such as coal and natural gas, its returns will compress and decrease the intrinsic value of the company. I mistakenly believed that following the general election held in March of 2008, the government would logically allow for a fuel cost pass-through. Unfortunately, the government barely won reelection and now has very little political capital to implement policy that, while economically sound, is politically unpopular. It is the unfortunate nature of politics that unsound policy that is popular often trumps sound policy that is unpopular. The decline in value of Tenaga following the election was harsh and swift, and unfortunately, justified. With coal prices globally skyrocketing, Tenaga will likely face a very difficult environment in the future.

Another investment mistake was the purchase of J.C. Penney Company, which declined approximately 24% in the period. Despite an obviously difficult retail environment, I believe the valuation of J.C. Penney reflected the difficulty, but didn’t

(unaudited)

reflect the potential impact of a turn-around engineered by CEO Mike Ullman. Unfortunately, it appears this was not the case as weakening sales at J.C. Penney had a disproportionately negative impact on margins. While I expected some of this, the magnitude of the impact surprised me and led me to conclude that the investment decision was a mistake. Though still cheap, during the period I began my complete sell off of the position. I believe any turn-around is likely to take substantially longer than I had anticipated.

The timing of the decision to buy biomedical company Amgen was another important mistake, as it declined nearly 28% in the period. One can never expect to pick the absolute bottom of a company’s stock price, but obviously the closer one comes, the better the potential for attractive future returns. Investing is a process of making decisions with incomplete information. In order to invest effectively, one must consider the likelihood of various outcomes and decide if the risk of a negative outcome is compensated by the potential return of a positive outcome. Unfortunately, sometimes the negative outcome occurs, even when one considers the probability of such an outcome as low. In the case of Amgen, I thought that the probability of a severe restriction on their Epogen and Aranesp drug franchise was low. Unfortunately, the unlikely occurred and resulted in a negative re-rating of the franchise, and therefore of itself. While further risks remain as I await more trials, I nonetheless believe that the current valuation indeed reflects a very negative environment and I have chosen to maintain the position, recognizing that I was wrong to have invested in Amgen when I did. Should further negative outcomes occur, downside certainly exists, but I do believe the upside opportunity compensates for that risk.

Two other important detractors were HMO Coventry Health Care (down slightly over 25%) and ICICI Bank (down approximately 36%). In the case of Coventry, despite weakness among its competitors and a slightly more challenging environment, I believe it remained an extremely well-run company and is extremely attractively valued relative to its returns. It is my view that despite a more severe correction than I would have expected, the decline in Coventry was an opportunity to buy more stock rather than exit the position. If the investment thesis is unchanged, volatility can be the friend of the long-term investor; I therefore chose to buy rather than sell.

ICICI Bank, despite being in my view a very well-run Indian bank, has clearly been penalized for being both a financial company and an Indian company, two very negative attributes in the period. Inflation is clearly accelerating in India, and compounded by increasing costs of credit, it is quite likely to have a negative impact on the demand for credit. Because of this, I chose to reduce the position slightly, despite what I see as an attractive valuation and a very strong management team.

Stocks that Aided Performance

I have chosen to spend the majority of this communication discussing the mistakes and poor performing positions because it is important to me that, as an investor in the Fund, you have a clear understanding of the factors that influenced the returns of your Fund, as well as an understanding about how your manager reacts to those situations. Since the returns of the Fund were substantially negative during the period, it logically follows that the failures should be highlighted more than the successes. That said, there were a few positions that contributed positively during the period. Global glass container manufacturer Owens-Illinois continued to contribute positively and was up slightly over 24% during the period. St. Joe, the largest private landowner in Florida, was up approximately 20% in the period after it had been substantially sold off last year as investors sold investments with exposure to residential real estate. Three energy companies, Forest Oil, Sandridge Energy and Chesapeake Energy, were all beneficiaries of strong oil and natural gas pricing and were up over 21%, 41%, and 31%, respectively.

Outlook

In conclusion, while I remain skeptical about strong equity returns in the face of global commodity inflation and credit contraction, interesting investment opportunities remain. In fact, I took advantage of the sell-off early this year to buy companies I believe were being cast aside without regard for valuation. Indeed, it is in these very types of difficult markets that some of the best opportunities arise. As an example, I was able to purchase a substantial position in ski destination Vail Resorts at a very attractive price because investors had feared that a difficult economy might hurt Vail’s business. That may or may not occur, but from my perspective, it doesn’t matter. The value of a company is the value of cumulative cash flows over time; a temporarily difficult economic environment should have no lasting impact on a franchise as powerful as Vail Resorts. In situations such as this, it is important to me to understand the valuation and buy aggressively when the opportunity presents itself. Our outstanding team of research analysts and I will continue to strive to take advantage of short-term market volatility to make long-term investments for Janus Contrarian Fund. Thank you again for your continued investment.

The Fund’s performance may be affected by risks that include those associated with non-diversification, 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 (“IPOs”) and derivatives. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and other details.

Funds that invest in Real Estate Investment Trusts (REITs) may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: legal, political, liquidity, interest rate risks, a decline in the value of real estate, risks related to economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Funds invest in foreign REITs, the Funds may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

The use of short sales may cause the fund to have higher expenses than those of other equity funds. Short sales are speculative transactions and involve special risks, including a greater reliance on the investment team’s ability to accurately anticipate the future value of a security. The Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s use of short sales in effect leverages the Fund’s portfolio. The Fund’s use of leverage may result in risks and can magnify the effect of any losses. There is no assurance that a leveraging strategy will be successful.

Returns include reinvestment of dividends from net investment income and distributions from 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.

26  Janus Core, Risk-Managed and Value Funds  April 30, 2008

Janus Fundamental Equity Fund (unaudited) Ticker: JAEIX

Fund Snapshot

This conservative growth fund relies on the Janus Research Team to drive its fundamental approach to investing in core holdings and opportunistic companies.

Team Based Approach
Led by Jim Goff,
Director of Research

Performance Overview

For the six-month period ended April 30, 2008, Janus Fundamental Equity Fund returned (10.83)%. The Fund underperformed its primary benchmark, the S&P 500^® Index, which returned (9.64)%, as well as its secondary benchmark, the Russell 1000^® Growth Index, which returned (9.28)%.

Economic Overview

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above the mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008.

Additional subprime-related write-offs, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations weighed on investor sentiment during the period. Stocks reached their lows in mid-March. Financial markets stabilized somewhat after the Federal Reserve (Fed) aggressively lowered the Federal Funds rate, expanded the collateral it would accept and played an instrumental role in JP Morgan Chase’s purchase of Bear Stearns. In the end, the Fed lowered its target interest rate from 4.50% to 2.00% during the period.

Overall, mid-cap stocks performed better than large- and small-cap stocks, while growth outperformed value stocks. For the broad market all sectors declined with the exception of energy, which turned in a gain for the six-month period amid record crude oil prices. Meanwhile, financials were the worst performing group, suffering from turmoil in the credit markets and larger-than-expected subprime-related write-downs. Information technology was also among the weakest performers while defensive sectors, like consumer staples, posted small declines.

Since November 7, 2007, Janus Fundamental Equity Fund has been team managed, representing the best ideas from Janus’ more than 30 equity analysts and Director of Research Jim Goff oversees the team. Individual analysts primarily drive stock selection, with debate and oversight provided by each one of the seven global sector research teams with which each analyst is aligned. We believe there is great power in individual analysts driving investment decisions, as they are most familiar with the stocks they cover. We strive to keep the Fund sector-neutral compared to its primary benchmark, although the Fund had over 16% non-U.S. exposure at the end of the period. The focus of the Fund is on capturing the best ideas of Janus’ research platform in an attempt to generate strong and consistent investment returns.

Stocks That Hurt Performance

Areas of weakness included the financials, technology and health care sectors, where select holdings fell short of our expectations. The subprime loan issues that have dominated the financial markets for months weighed on the stock price of home mortgage company Fannie Mae. Fannie Mae traded lower due to continued weakness in housing and credit markets. We believe that the company will benefit from the recent reduction in its capital surplus level, as well as improving returns on equity given the existing difference between mortgage rates and U.S. Treasury bond yields.

Staying within financials, E*Trade Financial suffered after the company reported large write-downs in its mortgage business. This weakness violated our initial investment thesis on the stock, which was focused on growth in the online brokerage and banking businesses to drive earnings. Given the mortgage losses impacting the company’s future growth prospects, the position was sold.

In the health care sector, pharmaceutical company Merck was the largest detractor during the period. Performance at Merck was driven largely by a report from the American College of Cardiology suggesting that doctors should limit prescriptions for the company’s jointly sold (with Schering-Plough) cholesterol drugs. The report stated that older, cheaper drugs could be just as effective. Last year, the two drug makers sold $5.2 billion of Vytorin and Zetia, combined. We will be watching the developments of Merck closely in the coming months.

Within the technology sector, EMC hindered performance in the period. This provider of network storage solutions, declined after its majority-owned subsidiary, VMware, provided conservative guidance, which weighed on the price of both stocks. We chose to exit the position.

Investments That Contributed to Performance

The energy sector and select industrials and technology holdings aided performance. Energy company Hess was the top contributor to performance for the period. The company benefited from the rising price of oil during the period, as well as increased appreciation for the future production potential from Hess’ new projects, including deep water projects in the Gulf of Mexico and off the coast of Brazil. Given the price appreciation in the period, we trimmed the position in order to harvest profits.

Oil and gas exploration company EOG Resources was another strong individual contributor during the period. Looking ahead, EOG has rights to shale formations in Canada, which are similar to its Texas formations. We believe this could be an attractive opportunity for EOG to increase its gas reserves.

In the industrials sector Canada-based Potash Corporation of Saskatchewan moved ahead, aided by continued demand and tight supplies. The company continued to benefit from global demand for agricultural products, which is expected to drive further growth in revenue and earnings industry wide. Potash itself is a critical ingredient used in fertilizers for key farming areas like the U.S., Brazil and China. Price increases for the commodity have been enacted for 2008 in many regions, which led to upward revisions in analysts’ estimates and provided a further tailwind for the company’s stock price.

Technology holding First Solar also contributed to performance during the six-month period. First Solar produces solar cells using thin-film technology, a specialized approach to solar energy production. The company continued to report strong results and growth as it ramps up its production due to demand.

Outlook

The Fund remains sector-neutral and we expect stock selection to be a key driver of returns going forward. Volatile markets tend to give many investors a reason to focus on the short term. Therefore, we believe we will see many opportunities for long-term investors to purchase good businesses at attractive prices. Looking ahead, we will continue to invest with conviction in areas where we feel we can develop an edge through research. Through our valuation discipline and focus on risk management, we remain committed to delivering superior long-term results for our clients.

Thank you for your investment in Janus Fundamental Equity Fund.

Janus Growth and Income Fund (unaudited) Ticker: JAGIX

Fund Snapshot

This growth fund seeks to create capital appreciation and income through all types of market conditions by leveraging the best ideas of the Janus Research Team.

Marc Pinto

portfolio manager

Performance Overview

For the six-month period ended April 30, 2008, Janus Growth and Income Fund returned (11.83)%. The Fund’s primary benchmark, the S&P 500^® Index, and its secondary benchmark, the Russell 1000^® Growth Index, returned (9.64)% and (9.28)%, respectively.

Economic Overview

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above the mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008.

Additional subprime-related write-offs, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept and played an instrumental role in JP Morgan Chase’s purchase of Bear Stearns. In the end, the Fed lowered its target interest rate from 4.50% to 2.00% during the period.

Overall, mid-cap stocks performed better than large- and small-cap stocks, while growth outperformed value stocks. For the broad market all sectors declined with the exception of energy, which turned in a gain for the six-month period amid record crude oil prices. Meanwhile, financials were the worst performing group, suffering from turmoil in the credit markets and larger-than-expected subprime-related write-downs. Information technology was also among the weakest performers while defensive sectors, like consumer staples, posted small declines. Following the March lows, the equity market’s rally at the end of the period can be attributed in part to improving sentiment as investors began to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs continued to weigh on the market.

Holdings within Information Technology, Financials and Industrials Detracted from Performance

Main areas of weakness during the period included the information technology, financials and industrials sectors. Within information technology, EMC was the largest detractor from performance during the six-month period. This provider of network storage solutions declined after its majority-owned subsidiary, VMware, provided conservative guidance, which weighed on the price of both stocks. We held onto the position in EMC given our view of the ongoing stability in the core storage business.

Looking at financials, the credit crisis that has dominated the financial markets for months weighed on the stock price of home mortgage provider Fannie Mae during the period. The stock traded lower due to continued weakness in housing and credit markets. We used the weakness to add to our position, as our research indicates that Fannie Mae will likely benefit from the recent reduction in its capital surplus level, as well as improving returns on equity, given the existing difference between mortgage rates and U.S. Treasury yields.

Staying within financials, E*Trade Financial suffered after the company reported large write-downs in its mortgage business. This weakness violated our initial investment thesis on the stock, which was focused on growth in the online brokerage and banking businesses to drive earnings. Given the mortgage losses impacting the company’s future growth prospects, the position was sold.

Within industrials, General Electric (GE) was also negatively impacted by the weakening economy. GE stock fell after reporting weaker-than-expected profits from its GE Capital division due to capital market disruptions and the inability to complete asset sales. Given our cautious outlook on the credit markets, we chose to reduce our exposure to this security.

Other stocks that negatively impacted performance included oil refiner Valero Energy. The stock declined after pre-announcing weaker than expected results due to refining outages caused by equipment issues, which impacted refining margins. We held the position due to the tight

Janus Growth and Income Fund (unaudited)

capacity in the refining sector and operational improvements taking place at the company.

Energy and Materials Sector Holdings Contributed to Performance

The primary sectors that contributed to Fund performance during the period were energy and materials. Hess, a leader in energy exploration and production, was the top contributor to performance for the period. The company benefited from the rising price of oil during the period, as well as increased appreciation for the future production potential from Hess’ new projects, including deep-water projects in the Gulf of Mexico and off the coast of Brazil. We believe that Hess remains undervalued given the potential reserves in these projects.

Staying within energy, Canada-based oil and gas exploration and production company EnCana gained ground in the period, aided by the increase in natural gas prices and news of interesting projects in Alberta, Canada. We maintained exposure to EnCana given, in our view, its attractive production growth profile, driven by its North American natural gas reserves. Furthermore, we have maintained our overweight position in the energy sector given our belief that demand will continue to outstrip supply.

Finally, our agriculture investments have generated positive returns for investors during the six-month period. Most notably, Canadian company Potash Corporation of Saskatchewan generated positive returns, driven by price increases for potash, a key ingredient for fertilizer. We believe the strength of the company’s competitive position can be evidenced by key price increases it has been able to announce with large trading partners like Brazil and southeast Asia.

Similarly, Syngenta, a leader in crop protection and genetically modified seeds, posted solid gains driven by strong sales in Latin America. We believe that the market is in a strong phase of the agriculture cycle right now and that Syngenta is well positioned to benefit from the desire of farmers to maximize crop yields.

Outlook

Looking ahead, we will be paying close attention to the employment picture, the availability of credit and U.S. consumer confidence, among other things. Should the labor market continue to soften amid continued weakness in the housing market, further slowing in consumer spending is likely. While the government stimulus checks could provide a temporary boost, the current de-leveraging of the U.S. economy could take time to complete, possibly lessening the potential for a sharp rebound in economic activity. Inflation remains a concern for the markets as well, given record commodity prices and its recent elevated level. Although inflation is generally a lagging indicator and should ease with slowing economic growth, it deserves attention given its negative impact and the notion that inflation may limit the Fed’s options to further stimulate economic growth.

Although export growth has been strong, helping to offset domestic weakness, and corporate balance sheets are generally healthy, something that has provided support for equity prices, markets are likely to tread cautiously. Nevertheless, we remain committed to our fundamental investment approach in our effort to find opportunities that we believe represent an attractive risk/reward profile. As always, we will continue to emphasize bottom-up company analysis as our primary tool in our quest to add value for shareholders.

Portfolio Positioning

Since taking over the Fund last November, I have worked to reduce the overall risk profile of the portfolio, given signs of economic deceleration. Steps I have taken include reducing the overweight and underweight sector weightings in the portfolio. For example, I have substantially reduced the position in the financials sector. I have also reduced the total number of holdings in the portfolio in order to focus on our highest-conviction ideas in this uncertain environment where we feel our research is truly differentiated. Finally, I have focused the income-related portion of the portfolio on traditional fixed-income holdings like U.S. Treasuries, corporate bonds and select preferred holdings. In summary, while the Fund underperformed the benchmarks for the period, I am pleased with the performance so far in 2008.

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

Janus Core, Risk-Managed and Value Funds  April 30, 2008  43

INTECH Risk-Managed Stock Fund (unaudited) Ticker: JRMSX

Fund Snapshot

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

Managed by INTECH

Performance Overview

For the six-month period ended April 30, 2008, INTECH Risk-Managed Stock Fund returned (8.84)%. This compares to the (9.64)% return posted by the S&P 500^® Index, the Fund’s benchmark.

Investment Strategy in This Environment

While INTECH does not employ fundamental analysis in the management of the Fund, fundamentals can have a significant impact on the general direction of the market in which we participate. The Fund’s goal is to produce long-term returns in excess of its benchmark with an equal or lesser amount of risk.

The Fund’s mathematical investment process seeks to build a more efficient portfolio than its benchmark, the S&P 500^® Index. With a focus on risk management, investment decisions are governed by a mathematical investment process. The 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

As stock prices moved naturally throughout the period, we continued to implement our mathematical process in a disciplined manner in an effort to maintain a more efficient portfolio than the Index, without increasing relative risk. 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.

In INTECH’s history, which spans more than 20 years, we have experienced six-month periods of similar magnitude in terms of both underperformance and outperformance. From our perspective, the key is to keep periods of underperformance both short in duration and mild in scope. INTECH aims to achieve its targeted returns over the long term and we believe the Fund remains well positioned for long-term capital growth.

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 implementing the process in a disciplined and deliberate manner in an effort to achieve our long-term performance goals. The Fund may underperform during shorter time periods, but has the goal of outperformance over a three- to five-year period. Managing risk remains essential to the investment process. We will continue to make marginal improvements to the mathematical process, seeking an efficient portfolio that offers better long-term results than the benchmark, regardless of the market’s direction.

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

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 has a performance-based management fee that adjusts up or down based on the Fund’s performance relative to an approved benchmark index over a performance measurement period.

A 2% redemption fee may be imposed on shares held for 90 days or less. Performance shown does not reflect this redemption fee and, if reflected, performance would have been lower.

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 fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2007. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.) 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 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.

The Fund’s performance may be affected by risks that include those associated with 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, initial public offerings (“IPOs”) and derivatives. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and details.

Funds that invest in Real Estate Investment Trusts (REITs) may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: legal, political, liquidity, interest rate risks, a decline in the value of real estate, risks related to economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Funds invest in foreign REITs, the Funds may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

Returns include reinvestment of dividends from net investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

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 unmanaged and is not available for direct investment; therefore its performance does not reflect the expenses associated with the active management of an actual portfolio.

Performance Overview

During the six months ended April 30, 2008, Janus Mid Cap Value Fund’s Investor Shares and Institutional Shares returned (3.78)% and (3.65)%, respectively, outperforming the Fund’s benchmark, the Russell Midcap^® Value Index, which returned (9.20)%. The S&P MidCap 400 Index returned (6.95)% and the S&P 500^® Index returned (9.64)% during the same period.

The concerns that we expressed in our last report severely impacted the market in the most recent six months. The problems of subprime lending, leverage and derivatives spread across financial markets. Credit availability became restricted, financial earnings suffered from huge write-offs, and investor confidence was shaken. As a result, the stock market experienced a correction, which at the low in January was down over 15% from its October high.

In general, our stocks held up relatively well compared to the benchmark because of a more risk-sensitive market that favored stocks with the characteristics we traditionally emphasize. We believe that in an uncertain financial environment it is likely that stocks with better balance sheets, strong free cash flow and valuations which incorporate more modest expectations will suffer less downside risk. These stocks may or may not fully participate in a short-term market rally (in fact, we lagged a bit in April), but we believe by doing fairly well in the downturn the likelihood is they will outperform over the full cycle. We are focused on the long term and the favorable impact that preservation of capital has on compounding returns for the Fund.

Merger and Acquisition Activity

As has been the case in each year other than 2002, merger and acquisition activity had a positive impact on the Fund. With the disruption in the credit markets, this activity nearly came to a halt in recent months. While private equity activity is likely to decline from the record levels seen in recent years, we believe that strategic and/or foreign buyers could step in, as evidenced by National-Oilwell’s fourth quarter buyout of Fund holding Grant Prideco and United Technologies’ bid for Fund holding Diebold. This buyout activity is a reinforcement of our belief that our long-standing investment process is successful in identifying strong, attractively valued franchises.

Holdings That Contributed to Performance

Strength in commodity prices was a help to our multi-year overweighted position versus the benchmark in energy – natural gas and crude oil were up approximately 30% and 20%, respectively, in the past six months. While energy prices could retrace some of this strength, we believe that prices will remain high because of tight supply. We still found attractive long-term value plays in the space, such as contributors Southwestern Energy and Sandridge Energy, which are mostly natural gas focused. In addition to initiating our position in Sandridge Energy, we made significant additions to our holding in Forest Oil, as the company continues to transform itself into a steady organic growth company while maintaining what we feel are some of the best cost controls in the industry.

For the six-month period, information technology was one of the worst performing sectors in the Index, but our information technology holdings declined about half as much as the rest of the group. Diebold was the largest individual contributor in this sector. Early this year, because of our confidence in the company’s franchise and long-term outlook, we added to our exposure despite disappointing short term earnings and what we believed to be minor accounting issues. In late February, United Technologies made a bid for the company at over a 60% premium to Diebold’s market price.

In the materials sector, leading fertilizer producer Mosaic was another top performer, which along with industrials sector holding, Deere, was a primary beneficiary of strong agricultural prices. Both holdings were reduced on strength.

Holdings That Detracted from Performance

Two of our five largest detractors were financial sector stocks. One of our best performers in the past, AllianceBernstein Holding, witnessed a correction of greater than 25% during the period after a modest near-term earnings shortfall due to reduced performance fees and general market weakness. We believe AllianceBernstein remains a growth franchise with good international exposure and a current dividend yield of over 5%. Regional bank Colonial BancGroup also underperformed, as it was one of many banks to suffer from real estate-related losses.

Packaging and building products manufacturer Temple-Inland was also penalized by the housing slowdown. The stock was the largest detractor for the period due to weakness in demand for building materials and continued increases in

(unaudited)

raw material prices. We added to our position in Temple-Inland on weakness, as the fundamentals in the packaging industry remain solid and we believe the company has the ability to improve margins. We feel Temple-Inland is trading at a substantial discount to its intrinsic value.

Market Outlook

Over the six-month period we have remained over 90% invested despite near-term economic and market uncertainty as we believe we have found some good long-term values to replace stocks whose risk/reward relationships have become less favorable in our view. We generally characterize our purchases as having better-than-average balance sheets, a likelihood of positive free cash flow even if earnings disappoint, and stock prices that are near their 12-month lows reflecting reduced expectations.

In terms of sector positioning, the relative exposures versus the benchmark remained as they have been for some time. At the end of April, we were overweight in energy, health care and information technology and underweight in consumer discretionary, financials and utilities. The relative weightings are more a reflection of the number of attractively valued stock opportunities we find within a sector than any macro-influenced sector allocation decision. Incidentally, we have been surprised that, in general, small caps have performed relatively well compared to large caps. We continue to think large caps have better risk/reward characteristics than small caps, but we are taking advantage of volatility in selected smaller mid caps to establish or increase positions.

April has seen the market rebound, but it’s unclear how long this respite will continue. The market has digested significant negative news and the Federal Reserve has been very aggressive in addressing the financial problems. However, we suspect the economy and earnings could decline more than expected and, in any case, any recovery is likely to be slow. The financial system’s leverage will take a long time to be rebalanced and is still subject to significant unanticipated shocks. In that context, the Fund has maintained its position in index puts. To date this program has been about break-even, but it has tempered short-term volatility and may be beneficial in a more severe downturn. We think this small investment in “market insurance” is consistent with our sensitivity to the need to preserve capital and our objective of continuing to provide consistent, above average long-term investment returns on both an absolute and relative basis. Please see “Notes to Financial Statements” for a discussion of derivatives used by the Fund.

Janus Small Cap Value Fund (unaudited) (closed to new investors) Ticker: JSCVX

Fund Snapshot

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

Managed by
Perkins, Wolf, McDonnell
and Company, LLC

Performance Overview

During the six months ended April 30, 2008, Janus Small Cap Value Fund’s Investor Shares and Institutional Shares returned (6.03)% and (5.96)%, respectively, versus a return of (11.55)% for the Fund’s benchmark, the Russell 2000^® Value Index.

During the six-month period ended April 30, 2008, the stock market suffered a strong decline as the idea of an economic recession this year became the consensus viewpoint. The U.S. Federal Reserve (Fed) attempted to stabilize equity markets in late January with an unprecedented inter-meeting 75-basis point emergency interest rate cut. The Fed followed that up with more easing in February, March and April. Market volatility remained elevated after years of calm amid heightened credit concerns, illustrating how delicate the credit markets have become and the prevailing nervousness in the financial markets. The latest attempts by the Fed to address the credit crisis seemed to be working to steady financial markets somewhat as some investor sentiment gauges recently displayed evidence of cautious optimism.

In this environment our standard risk-sensitive investment approach, emphasizing balance sheet strength, strong free cash flow and stocks pricing in fairly low expectations, has allowed the Fund to hold up relatively well. As was the case last period, most of our outperformance was attributable to positive stock selection.

Holdings That Contributed To Performance

The industrials sector had the best performance versus the benchmark over the last six months. Agricultural distributor UAP Holding, one of the five largest positions in the portfolio during the period, was also among the strongest contributors after fertilizer producer Agrium announced in late February it would purchase the company at a 30% premium to its prior day closing price. Separately, business service provider Navigant Consulting was also among the strongest contributors after management cited an increase in their project pipeline due to an increase in subprime litigation. Railroad and trucking stocks also outperformed, and our overweight in the group was a positive, as investors began rotating into stocks that typically lead during the early stages of an economic turnaround. Kansas City Southern, Heartland Express, and Saia all benefited from this trend. We eliminated Saia from the Fund as it reached our price target.

Within health care, Perrigo, a generic drug manufacturer, delivered strong returns during the period after announcing progress in their pipeline that should help drive growth going forward. We built our position in the company over many years, believing the stock to be undervalued with respect to operational improvements and growth potential in their generic business. The stock was among our 10 largest holdings at the beginning of the period, but we have sold two thirds of our shares as much of the valuation gap has disappeared. While information technology was one of the worst performing sectors in the benchmark, our holdings within the sector declined less than those within the benchmark. Automated teller manufacturer Diebold was the largest individual contributor in this sector. Early in the first quarter of 2008, because of a very attractive free cash flow yield, confidence in the company’s franchise and long-term outlook, we more than doubled our position in the stock despite disappointing earnings and what we believed to be minor accounting issues. In February, aerospace equipment company United Technologies made a cash bid for the company at over a 60% premium to Diebold’s market price.

Holdings That Detracted From Performance

Within information technology, Global Positioning System provider, SiRF Technology Holdings underperformed after reporting disappointing quarterly results, citing margin compression and lack of pricing power. We decided to eliminate our position in SiRF due to the deterioration in the company’s fundamentals.

After strong relative performance in 2007, our financial holdings were down in line with the benchmark for the period due primarily to regional banks Boston Private Financial Holdings and South Financial Group. After telling investors that their portfolio remained in good shape in January, Boston Private surprised investors a month later by announcing credit problems in one of their divisions. We decided to exit our position in Boston Private as we felt less comfortable with the strength of the balance sheet if further problems were to arise. The shares of South Financial Group followed a similar path. We sold nearly half of the shares we owned in the first quarter of 2008 at higher prices as the credit problems of their southeastern peers had yet to be recognized by the bank. With their first quarter earnings report came recognition and a substantially lower stock price. An announced secondary offering and reduced dividend caused further declines. However, we believe these actions improved

the capital structure of the bank, and with the stock trading well below tangible book, we added to our position late in the period.

The Fund continues to be underweight in the financials sector, as it generally has been for the last four years. Considering the sector’s approximately 33% weight in the benchmark at the end of the period, and the fact that next to consumer discretionary stocks, financials have shown the steepest price decline over the last year, the relative benefit of our position recently is obvious. It could be asked why we have yet to become even equally weighted given the declines and improving valuations relative to book value and longer-term earnings power. Outside of the largest overall detractor from performance, Boston Private Financial Holdings, where credibility became an issue, our stock selection has been very good for the last year. This is primarily due to being disciplined in identifying potential downside risk before getting caught up in the promise of upside in a recovery. We believe patience is warranted as the financial markets continue to sort out the credit issues, which could take some time. We will continue to evaluate opportunities on a case-by-case, bottom-up basis.

Market Outlook

We believe the market has rebounded nicely since the March lows, but it is unclear how long this respite will continue. The market has digested significant negative news and the Fed has been very aggressive in trying to address financial problems. However, we suspect the economy and earnings could decline more than expected and, in any case, any recovery is likely to be slow. We believe the financial system’s leverage will take a long time to be rebalanced and is still subject to significant unanticipated shocks.

With very few exceptions, we believe our purchases are of companies with better-than-average balance sheets, with a greater likelihood of positive free cash flow even if earnings disappoint, and with stock prices that are nearing their 12-month lows, reflecting reduced expectations. Our ability to uncover stocks with these characteristics that we believe also have attractive risk/reward relationships, has continued to drive our level of investment. These stocks may or may not fully participate in a short-term market rally, but we believe by doing better in the downturn it is likely they will outperform over the full cycle. We have remained around 90% invested at the end of the six-month period despite near-term economic and market uncertainty as elevated volatility has enabled us to find what we believe to be some good long-term values. However, we are also sensitive to sharply positive swings in the stocks we own and will continue to pare back and sell those positions that approach and reach our modest objectives. We are focused on the long-term and the favorable impact that preservation of capital has on compounding returns for the Fund.

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

Janus Services LLC has contractually agreed to waive the transfer agency fees applicable to the Fund’s Institutional Shares to the level indicated until at least March 1, 2009. Returns shown include fee waivers, if any, and without such waivers, the Fund’s returns would have been lower.

The fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2007. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.) Contractual waivers agreed to by Janus Capital, where applicable, are included in the prospectus 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.

(unaudited)

The Fund’s performance may be affected by risks that include those associated with, 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 (“IPOs”), derivatives and companies with relatively small market capitalizations. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and other details.

Funds that invest in Real Estate Investment Trusts (REITs) may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: legal, political, liquidity, interest rate risks, a decline in the value of real estate, risks related to economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Funds invest in foreign REITs, the Funds may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

Returns include reinvestment of dividends from net investment income and distributions from 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.

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 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 is 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 twenty-nine funds. The Funds invest primarily in equity securities. Each Fund 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.

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. Circumstances in which fair value pricing may be utilized include, but are not limited to: (i) when significant events occur which may affect the securities of a single issuer, such as mergers, bankruptcies, or significant issuer-specific developments; (ii) when significant events occur which may affect an entire market, such as natural disasters or significant governmental actions; and (iii) when non-significant events occur such as markets closing early or not opening, security trading halts, or pricing of non-valued securities and restricted or non-public securities. 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. Dividends from foreign securities may be subject to withholding taxes in foreign

Janus Core, Risk-Managed and Value Funds  April 30, 2008  89

Notes to Financial Statements (unaudited) (continued)

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. Income, as well as gains and losses, both realized and unrealized, 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

The Funds bear expenses incurred specifically on their behalf as well as a portion of general expenses. Janus Mid Cap Value Fund and Janus Small Cap Value Fund currently offer two classes of shares. Each class of shares 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 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.

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. 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 if time permits. 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, time deposits, repurchase agreements, money market mutual funds or other money market accounts, 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.

Dresdner Bank AG (the “Lending Agent”) may also invest the cash collateral in the Allianz Dresdner Daily Asset Fund 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.

As of April 30, 2008, the Funds had on loan securities valued as indicated:

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 loaned 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 the Lending Agent. The Lending Agent may retain a portion of the interest earned on the cash collateral invested. The cash collateral invested by the Lending Agent is disclosed in the Schedule of Investments (if applicable). The lending fees and the Funds’ portion of the interest income earned on cash collateral are included on the Statement of Operations (if applicable).

Interfund Lending

Pursuant to an exemptive order received from the SEC, each Fund may be party to interfund lending agreements between the Fund 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 the 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, 2008, there were no outstanding interfund borrowing or lending arrangements for the Funds.

Forward Currency Transactions

The Funds, except INTECH Risk-Managed Stock Fund, may enter into forward currency contracts in order to reduce exposure to changes in foreign currency exchange rates on 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 investment and 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.

Futures Contracts

The Funds may enter into futures contracts to gain exposure to the stock market pending investment of cash balances or to meet liquidity needs. The Funds may also 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 values 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 as “Net realized gain/(loss) from futures contracts” 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.

Swaps

The Funds, except INTECH Risk-Managed Stock Fund, may enter into swap agreements to hedge exposure to interest rates and credit risk or for investment purposes. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. Swap contracts are reported as an asset and liability on the Statement of Assets and Liabilities. Realized gains and losses are reported in “Net realized gain/(loss) from swap contracts” on the Statement of Operations (if applicable).

Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the swap contract. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Funds, and/or the termination value. Therefore, the Funds consider the creditworthiness of each counterparty to a swap contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities.

Options Contracts

The Funds may purchase or write put and call options on futures contracts and on portfolio securities for hedging purposes or as a substitute for an investment. The Funds, except INTECH Risk-Managed Stock Fund, may also purchase or write put and call options on foreign currencies in a manner similar to that in which futures or forward contracts on foreign currencies will be utilized. The Funds may also invest in Long-Term Equity Anticipation Securities (LEAPS), which are long-term option contracts that can be maintained for a period of up to three years. The Funds generally invest in options to hedge against adverse movements in the value of portfolio holdings.

Notes to Financial Statements (unaudited) (continued)

When an option is written, the 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 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 Funds could result in the Funds 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 are adjusted by the amount of premium received or paid.

The Funds may also purchase and write exchange-listed and over-the-counter put and call options on domestic securities indices, and on foreign securities indices listed on domestic and foreign securities exchanges. Options on securities indices are similar to options on securities except that (1) the expiration cycles of securities index options are monthly, while those of securities options are currently quarterly, and (2) the delivery requirements are different. Instead of giving the right to take or make delivery of securities at a specified price, an option on a securities index gives the holder the right to receive a cash “exercise settlement amount” equal to (a) the amount, if any, by which the fixed exercise price of the option exceeds (in the case of a put) or is less than (in the case of a call) the closing value of the underlying index on the date of exercise, multiplied by (b) a fixed “index multiplier.” Receipt of this cash amount will depend upon the closing level of the securities index upon which the option is based being greater than, in the case of a call, or less than, in the case of a put, the exercise price of the index and the exercise price of the option times a specified multiple. The writer of the option is obligated, in return for the premium received, to make delivery of this amount.

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 as “Options written at value” (if applicable).

Realized gains and losses are reported as “Net realized gain/(loss) from options contracts” on the Statement of Operations (if applicable). The Funds recognized realized gains/(losses) from written options contracts during the six-month period ended April 30, 2008 as indicated in the table below:

Fund	Gains/(Losses)
Core
Janus Contrarian Fund	$	16,935,391
Janus Fundamental Equity Fund		1,140,857
Value
Janus Mid Cap Value Fund		(22,803,337)

The risk in writing call options is that the Funds give up the opportunity for profit if the market price of the security increases and the option is exercised. The risk in writing put options is that the Funds may incur a loss if the market price of the security decreases and the option is exercised. The risk in buying options is that the 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 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 Funds’ 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 the Funds may recognize due to written call options.

Floating Rate Loans

Janus Balanced Fund may invest in floating rate loans. Floating rate loans are debt securities that have floating interest rates tied to a benchmark lending rate such as the London Interbank Offered Rate (“LIBOR”). LIBOR is a short-term interest rate that banks charge one another and that is generally representative of the most competitive and current cash rates. In other cases, the lending rate could be tied to the prime rate offered by one or more major U.S. banks or the rate paid on large certificates of deposit traded in the secondary markets (“the CD Rate”). If the benchmark lending rate changes, the rate payable to lenders under the loan will change at the next scheduled adjustment date specified in the loan agreement. Floating rate loans are typically issued to companies (“borrowers”) in connection with recapitalizations, acquisitions, and refinancings. Floating rate loan investments are generally below investment grade. Senior floating rate loans are secured by specific collateral of a borrower and are senior in the borrower’s capital structure. The senior position in the borrower’s capital structure generally gives holders of senior loans a claim on certain of the borrower’s assets that is senior to subordinated debt and preferred and common stock in the case of a borrower’s default. Floating rate loan investments may involve foreign borrowers, and investments may be denominated in foreign currencies. Floating rate loans often involve borrowers whose financial condition is troubled or uncertain and companies that are highly leveraged. The Fund may invest in obligations of borrowers who are in bankruptcy proceedings. Floating rate loans may include fully funded term loans or revolving lines of credit.

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, 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 periodically to an increment over a designated benchmark rate, such as the one-month, three-month, six-month, or one-year 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 and the related rate range during the six-month period ended April 30, 2008, are indicated in the table below.

	Average Monthly
Fund	Value		Rates
Core
Janus Balanced Fund	$	10,850,677		1.50% - 7.448%

Short Sales

The Funds, except INTECH Risk-Managed Stock Fund, may engage in “short sales against the box.” Short sales against the box involve either selling short a security that the Funds own, or selling short a security that the Funds have the right to obtain, for delivery at a specified date in the future. The Funds may enter into short sales against the box to hedge against anticipated declines in the market price of portfolio securities. The Funds do not deliver from their portfolios the securities sold short and do not immediately receive the proceeds of the short sale. The Funds borrow the securities sold short and receive proceeds from the short sale only when they deliver the securities to the lender. If the value of the securities sold short increases prior to the scheduled delivery date, the Funds lose the opportunity to participate in the gain.

The Funds, except INTECH Risk-Managed Stock Fund, may also engage in other short sales. The Funds may engage in short sales when the portfolio managers and/or investment personnel anticipate that a security’s market purchase price will be less than its borrowing price. To complete the transaction, the Funds must borrow the security to deliver it to the purchaser and buy that same security in the market to return it to the lender. The total market value of all of a Fund’s short sales positions will not exceed 10% of its net assets. Although the potential for gain as a result of a short sale is limited to the price at which the Fund sold the security short less the cost of borrowing the security, the 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

Janus Core, Risk-Managed and Value Funds  April 30, 2008  93

Notes to Financial Statements (unaudited) (continued)

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 to the size of any loss that the Fund may recognize upon termination of a short sale. Short sales held by the Funds are fully collateralized by other securities, which are denoted in the accompanying Schedule of Investments (if applicable).

Foreign Currency Translations

The Funds do not isolate that portion of the results of operations resulting from the effect of 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 of investments and foreign currency translations 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 foreign 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.

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 Funds may hold liquid assets as collateral with the Funds’ custodian sufficient to cover the purchase price.

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 non-registered 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

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 their assets grow.

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 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, as amended. 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. As of April 30, 2008, Janus Balanced Fund, Janus Fundamental Equity and Janus Growth and Income Fund were invested in restricted securities.

Dividend Distributions

Dividends of net investment income for Janus Balanced Fund and Janus Growth and Income Fund are generally declared and distributed quarterly, and realized 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.

The Funds may make certain investments in real estate investment trusts (“REITs”) which pay dividends to their shareholders based upon funds available from operations. It

94  Janus Core, Risk-Managed and Value Funds  April 30, 2008

is quite common for these dividends to exceed the REIT’s taxable earnings and profits, resulting in the excess portion of such dividends being designated as a return of capital. If a Fund distributes such amounts, such distribution could constitute a return of capital to shareholders for federal income tax purposes.

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.

The Funds adopted the provisions of Financial Accounting Standards Board (“FASB”) Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes on April 30, 2008. FIN 48 requires an evaluation of tax positions taken (or expected to be taken) in the course of preparing a Fund’s tax return to determine whether these positions meet a “more-likely-than-not” standard that based on the technical merits have a more than fifty percent likelihood of being sustained by a taxing authority upon examination. A tax position that meets the “more-likely-than-not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations.

FIN 48 requires management of the Funds to analyze all open tax years, fiscal years 2003 – 2006 as defined by Statute of Limitations, for all major jurisdictions, including federal tax authorities and certain state tax authorities. As of and during the six-month period ended April 30, 2008, the Funds did not have a liability for any unrecognized tax benefits. The Funds have no examination in progress and are not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

New Accounting Pronouncements

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS No. 157”), which defines fair value, established a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS No. 157 does not require new fair value measurements, but is applied to the extent that other accounting pronouncements require or permit fair value measurements. SFAS No. 157 emphasizes that fair value is a market-based measurement that should be determined based on the assumptions that market participants would use in pricing an asset or liability. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. Management does not believe the adoption of SFAS No. 157 will impact the financial statement amounts; however, the Funds will be required to disclose the extent to which fair value is used to measure assets and liabilities and the inputs used to develop the measurements.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS No. 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. SFAS No. 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. SFAS No. 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. Management does not believe the adoption of SFAS No. 159 will impact the financial statement amounts.

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS No. 161”), which requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. SFAS No. 161 is effective for financial statements issued for fiscal years beginning after November 15, 2008, and interim periods within those fiscal years. Management is in the process of evaluating the impact of SFAS No. 161 on the Funds’ financial statement disclosures.

Notes to Financial Statements (unaudited) (continued)

2.  Investment Advisory Agreements and Other Transactions with Affiliates

The Funds pay a monthly advisory fee to Janus Capital based upon average daily net assets and calculated at the annual rate shown in the table below:

	Average Daily Net		Management
Fund	Assets of Fund		Fee (%)
Core
Janus Balanced Fund		All Asset Levels		0.55%
Janus Contrarian Fund		All Asset Levels		0.64%
Janus Fundamental Equity Fund		All Asset Levels		0.60%
Janus Growth and Income Fund		All Asset Levels		0.62%
Risk-Managed
INTECH Risk-Managed Stock Fund		All Asset Levels		0.50%
Value
Janus Mid Cap Value Fund		All Asset Levels		0.64%
Janus Small Cap Value Fund		All Asset Levels		0.72%

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. 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 the Fund’s performance relative 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 the 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 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 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 the Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s Investor Shares against the investment record of its 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 Fund’s prospectus and statement of additional information contain 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. During the six-month period ended April 30, 2008, the Funds recorded

96  Janus Core, Risk-Managed and Value Funds  April 30, 2008

the following Performance Adjustment as indicated in the table below:

	Performance
Fund	Fee
Janus Contrarian Fund	$	4,126,611
INTECH Risk-Managed Stock Fund	$	(359,800)
Janus Mid Cap Value Fund	$	4,489,048

Enhanced Investment Technologies, LLC (“INTECH”) serves as subadviser to INTECH Risk-Managed Stock Fund. Janus Capital indirectly owns approximately 89.9% of the outstanding voting shares of INTECH. Janus Capital pays INTECH a subadvisory fee equal to 0.26% of INTECH Risk-Managed Stock Fund’s average daily net assets during the previous month, plus or minus one-half of any performance fee adjustment paid to Janus Capital by the Fund, pursuant to the Fund’s investment advisory agreement. The Performance Adjustment impacts the current subadvisory fee as of January 1, 2007, when the Performance Adjustment took effect.

Perkins, Wolf, McDonnell and Company, LLC (“Perkins”) serves as subadviser to Janus Mid Cap Value Fund and Janus Small Cap Value Fund (each, a “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 Fund 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, 2009 to waive the transfer agency fee payable so that the total operating expenses (excluding extraordinary expenses and the 0.05% administrative services fee) of 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 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 asset levels 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 the Fund for the six-month period ended April 30, 2008 is indicated in the table below:

For the six-month period ended April 30, 2008, Janus Capital assumed $16,904 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 the Pending Legal Matters. 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 the Funds or Portfolios that commenced operations after July 31, 2004. Additionally, all future non-recurring costs will be allocated to the Portfolios based on 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 Board of Trustees has adopted a deferred compensation plan (the “Deferred 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 are credited to the account. The fluctuation of the account balance is recorded by the Funds as unrealized appreciation/(depreciation) and is shown as of April 30, 2008 on the Statement of Assets and Liabilities as an asset, “Non-interested Trustees’ deferred compensation,” and a liability, “Non-interested Trustees’ deferred compensation fees.” Additionally, the recorded unrealized appreciation/(depreciation) is included in “Unrealized net appreciation/(depreciation) of investments, foreign currency translations and non-interested Trustees’ deferred compensation” on the Statement of Assets and Liabilities. Deferred compensation expenses for the six-month period ended April 30, 2008 are included in “Non-interested Trustees’ fees and expenses” on the Statement of Operations. Trustees are allowed to change their designation of mutual funds from time to time. Amounts will be deferred until distributed in accordance with the Deferred Plan. No deferred fees were paid to any Trustee under the Deferred Plan during the six-month period ended April 30, 2008.

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 Trust. Total compensation of $39,907 was paid by the Trust during the six-month period ended April 30, 2008. Each Fund’s 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 credits or offsets are included in “Expense and Fee Offset” 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.

The Funds may invest in money market funds, including funds managed by Janus Capital. During the six-month period ended April 30, 2008, the following Funds recorded distributions from affiliated investment companies as affiliated dividend income, and had the following affiliated purchases and sales:

4.  Federal Income Tax

Income and capital gains distributions are determined in accordance with income tax regulations that may differ from accounting principles generally accepted in the United States of America. These differences are due to differing treatments for items such as net short-term gains, deferral of wash sale losses, foreign currency transactions, net investment losses and capital loss carryovers.

The Funds have elected to treat gains and losses on forward foreign currency contracts as capital gains and losses. Other foreign currency gains and losses on debt instruments are treated as ordinary income for federal income tax purposes pursuant to Section 988 of the Internal Revenue Code.

The aggregate cost of investments and the composition of unrealized appreciation and depreciation of investment securities for federal income tax purposes as of April 30, 2008 are noted below.

Unrealized appreciation and unrealized depreciation in the table below exclude appreciation/depreciation on foreign currency translations. The primary difference between book and tax appreciation or depreciation of investments are wash sale loss deferrals and passive foreign investment companies.

6.  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 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. The appeal is still pending and argument in the matter was held in December 2007. 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. However, in June 2007, Plaintiffs appealed that dismissal to the United States Court of Appeals for the Fourth Circuit. That appeal is currently pending.

In addition to the lawsuits described above, the Auditor of the State of West Virginia (“Auditor”), in his capacity as securities

Janus Core, Risk-Managed and Value Funds  April 30, 2008  101

Notes to Financial Statements (unaudited) (continued)

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 status conference was held on June 28, 2007, during which the parties were ordered to submit their proposed scheduling order. To date, no scheduling order has been entered in the case. In addition to the pending Motion to Discharge Order to Show Cause, 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.

During 2007, two lawsuits were filed against Janus Management Holdings Corporation (“Janus Holdings”), an affiliate of JCGI, by former Janus portfolio managers, alleging that Janus Holdings unilaterally implemented certain changes to compensation in violation of prior agreements. These complaints allege some or all of the following claims: (1) breach of contract; (2) willful and wanton breach of contract; (3) breach of good faith and fair dealing; and (4) estoppel. Janus Holdings filed Answers to these complaints denying any liability for these claims and intends to vigorously defend against the allegations.

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, none of whom has ever been affiliated with Janus Capital (“Independent Trustees”), oversee the management of each Fund 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 Fund, 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 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 with management to consider the agreements, and also met separately in executive session with their independent legal counsel and their independent fee consultant.

At a meeting held on December 14, 2007, based on their evaluation of the information provided by Janus Capital, the subadvisers and the independent fee consultant, as well as other information, the Trustees determined that the overall arrangements between each Fund and Janus Capital and each subadviser, as applicable, 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 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, 2008 through February 1, 2009 (January 1, 2008 through January 1, 2009 for INTECH Risk-Managed Stock Fund and Janus Global Research Fund), subject to earlier termination as provided for 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, the knowledge of 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 and/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 those 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

Janus Core, Risk-Managed and Value Funds  April 30, 2008  103

Additional Information (unaudited) (continued)

appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract well-qualified personnel.

Performance of the Funds

The Trustees considered the investment performance 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 many 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 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, 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.

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 fee rates for Funds having a similar strategy, the Trustees noted that, under the terms of 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, the Trustees 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.

The Trustees reviewed information on the profitability to Janus Capital and its affiliates of their relationships with each Fund, as well as an explanation of the methodology used in allocating various expenses of Janus Capital and its affiliates among the Funds and other clients. They 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 receives adequate incentives to manage the Funds effectively. They 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 adviser, 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 payable by Janus Capital or the Funds to the subadvisers of subadvised Funds, were reasonable in relation to the nature, extent 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 subadvisers charge to other clients. They 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, those Funds benefited from having advisory fee rates that remained constant rather than increasing as assets declined. In addition, performance fee structures have been

104  Janus Core, Risk-Managed and Value Funds  April 30, 2008

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. They also considered Janus Capital’s past and proposed use of commissions paid by Funds on their portfolio brokerage transactions to obtain proprietary and third-party research products and services benefiting those Funds and/or other clients of Janus Capital. The Trustees concluded that Janus Capital’s use of “soft” commission dollars of a Fund to obtain proprietary and third-party 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 also concluded that Janus Capital benefits from the receipt of proprietary and third-party 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, all of whom are 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 (from inception) 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 dividends and distributions, 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, 2007. 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 written options contracts follows each Fund’s Schedule of Investments (if applicable). Written options 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.

106  Janus Core, Risk-Managed and Value Funds  April 30, 2008

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 will 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 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 and expense reimbursements, if any, are also shown.

The last section lists the increase or decrease in the value of securities held in the Funds. The 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 Funds’ 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 will 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 withdrawals via redemptions. “Redemption Fees” (if applicable) refers to the fee paid to the Funds for shares held for 90 days 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 each Fund’s net asset value (“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 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 frequency of dividend payments 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 the offset and the net expenses. The

Janus Core, Risk-Managed and Value Funds  April 30, 2008  107

Explanations of Charts, Tables and
Financial Statements (unaudited) (continued)

expense ratios listed in the Financial Highlights reflect total expenses prior to any expense offset (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 size asset 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 Core, Risk-Managed and Value Funds  April 30, 2008  109

Janus provides access to a wide range of investment disciplines.

Asset Allocation

Janus asset allocation portfolios 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.

Co-Chief Investment Officers’ Letter to the Shareholders

Jonathan Coleman

Co-Chief Investment Officer

Gibson Smith

Co-Chief Investment Officer

Dear Shareholders,

Challenging economic conditions have been the dominant theme for the financial markets over the past several months. Despite recent volatility, our investment team has maintained a relentless focus on our fundamental, bottom-up research process and has continued to discover compelling investment opportunities for our shareholders.

Major Market Themes

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above their mid-March lows, stocks were broadly lower over the six months ended April 30, 2008. The Russell 1000^® Index declined 9.54%, the Russell 2000^® Index was down 12.92% and the Morgan Stanley Capital International (MSCI) All Country World Index^SM gave up 9.47% during the period. Fixed-income markets proved to be volatile over the period with the Lehman Brothers Aggregate Bond Index up 4.08% and the Lehman Brothers High-Yield Bond Index lost 0.74% over the period.

Additional write-offs related to the loose lending practices over the previous 36 months, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Uncertain market conditions resulted in interest rates hitting five-year lows with the 10-Year Treasury Note touching 3.33%. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the funding and credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept, allowed for broker/dealers to borrow directly from the Fed and played an instrumental role in JP Morgan Chase’s purchase of near-defunct Bear Stearns. All of these moves were vitally important toward stabilizing the financial system while allowing for the recovery process to continue. By the end, the Fed had lowered its target interest rate from 4.50% to 2.00% during the period.

Following the March lows, the equity market’s rally at the end of the six-month period can be attributed to the moves by the Fed and, in part, to improving sentiment as investors began to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs continued to weigh on the market.

Performance Notables

For the one-year period ended April 30, 2008, 77% of Janus’ retail funds ranked within Lipper’s top two quartiles, based upon total returns. The results were even stronger over longer time periods as 87% of our retail funds achieved first- or second-quartile Lipper rankings over three years and 86% ranked in Lipper’s top two quartiles over five years. Furthermore, 78.3% of our retail funds had a 4- or 5-star overall Morningstar Rating^tm as of April 30, 2008, well ahead of the 32.5% of funds for which Morningstar awards 4- or 5-stars in each category. (See complete Lipper rankings on page 3 and complete Morningstar Ratings^tm on page 4).

Investment Team Update

We continue to enhance the breadth of our global stock coverage and work tirelessly to generate solid investment insights in an attempt to deliver superior investment performance. Our hands-on research approach is critical to our stock selection process. As such, the Janus equity research team traveled over 2.9 million miles in 2007 investigating potential stock and bond picks worldwide. This year, we plan to embark on a multi-year strategy to locate certain investment personnel closer to the companies that they research as an important first step in building out our global footprint from a research standpoint.

While our objective is to develop a research edge and invest with conviction in our funds, we seek to do so in a disciplined and thoughtful way by clearly understanding and managing risk in our portfolios. Dan Scherman, Director of Risk and Trading, works continually with our investment management

team to ensure that portfolio risks are intentional and calculated. We believe this analysis is both timely and critical as we navigate today’s challenging markets.

Conclusion

As we look back over the past six months, we are relieved that signs of stabilization appeared in the financial markets as the period came to a close. However, we recognize that there are still significant challenges ahead. Increasing risk aversion has resulted in a significant contraction of credit availability for both consumers and corporations. The tightening of credit, along with declining real estate prices, rising energy prices and a climbing unemployment rate may all create significant economic headwinds in the near future. While unsettling, we believe this is a natural and necessary process of recovery from the excessive risk-taking and loose lending standards that developed over the previous several years in many areas of the credit markets. We feel that the environment will improve as the healing process progresses.

So, as we look ahead, we are paying very close attention to the outlook for the global economy, with a keen focus on slowing growth in the United States and the growth rates of the emerging economies around the globe. As these emerging economies become more prosperous, they may be able to move from economies based exclusively on exports fueling their growth to more balanced models emphasizing both exports and internal consumption of the goods they produce. Over a longer period of time, we believe this creates more stability in the global economy. We are also watching rising energy and commodity prices and their impact on inflationary expectations and the absolute level of interest rates. In addition to interest rates, we are focused on the outlook for the housing market and the implications of changes in home prices on the underlying health of the financial system, believing that the recapitalization of the banking and brokerage sectors is a vitally important element of the healing process.

While market volatility is undoubtedly challenging, it can also create an environment that can result in incredibly compelling investment opportunities. Our top priority is to remain committed to our process of in-depth fundamental research, which has been at the core of our investment process since Janus’ inception in 1969. With this singular focus we strive to deliver consistent long-term results for our shareholders.

Thank you for your continued investment in Janus funds.

Sincerely,

Jonathan Coleman

(2)	Closed to new investors.

Data presented reflects past performance, which is no guarantee of future results.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating^TM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of the funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variation in the distribution percentages.)

Useful Information About Your Fund Report

Management Commentaries

The Management Commentaries in this report include valuable insight from each of 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, 2008. As the investing environment changes, so could the managers’ 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, 2007 to April 30, 2008.

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 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 Global Research Fund’s total operating expenses, excluding brokerage commissions, interest, taxes, dividends and extraordinary expenses, to certain limits until at least March 1, 2009. 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

Janus Global Opportunities Fund returned (15.00)% over the six-month period ended April 30, 2008, underperforming its primary benchmark, the Morgan Stanley Capital International (MSCI) World Index^SM, which returned (9.37)% during the period.

Economic Overview

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. and global economies and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and world equity markets finished well above the mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008.

Additional subprime-related write-offs, slowing U.S. consumer spending and a softening U.S. labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the credit markets. World markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept and played an instrumental role in JP Morgan Chase’s purchase of Bear Stearns.

Overall, emerging market stocks in Latin America were among the biggest winners during the period amid continued strength in commodity prices. Developing markets in Asia were weak, with China suffering a sharp decline on worries over slowing export growth. In local currency terms, developed non-U.S. markets underperformed both emerging markets and U.S. stocks. The U.S. dollar weakened versus most major currencies for much of the period as concern over economic growth and a more accommodative Fed helped to fuel the negative sentiment toward it. Losses were broad across all sectors. Energy and materials were the only sectors to turn in a gain for the six-month period as the price of oil and other commodities soared. Meanwhile, financials and consumer discretionary stocks were the worst performing groups, suffering from turmoil in the credit markets, larger-than-expected subprime-related write-downs and a weakening economic outlook.

Following the March lows, the equity markets’ rally at the end of the period can be attributed in part to improving sentiment as investors began to look ahead to a possible economic recovery in the U.S. Nevertheless, concerns about elevated inflationary pressures, soft U.S. consumer spending, the weak U.S. housing market and the lingering possibility of more write-downs, continued to weigh on the market.

Stocks That Hindered Performance

The largest detractor from performance during the period was Dell. Worries over Dell’s exposure to the U.S. economy, and more importantly questions about their ability to succeed in their turnaround efforts weighed on the shares. We continue to believe Dell is a highly attractive investment, given its numerous competitive strengths, proven track record of high economic profitability and very well-capitalized balance sheet. Additionally we consider management, who are sizable owners themselves, to be highly capable. We think the company has a number of opportunistic initiatives in place which can improve business results over the coming years.

Apollo Group, which runs for-profit universities, fell in response to fears around its credit exposure and a dip in margins in February. With only a small fraction of their revenue coming from private loans, as opposed to government loans, we believe this issue is over-blown. Regarding margins, Apollo’s business has historically been highly profitable, but has varied from period–to-period, depending on such factors as the level of advertising and promotion expenditures and their ability to leverage their investment in instructional costs. Both of these concerns drove the share price lower during the period, however we believe they are very short-term in nature. We continue to be optimistic that the increasing need for higher education will provide a backdrop against which Apollo can generate meaningful growth over the long-term.

Stocks That Aided Performance

The top contributor to performance during the period was Nipponkoa Insurance Company. This top five non-life insurer in Japan is a conservatively managed company that has a long

6  Janus International and Global Funds  April 30, 2008

(unaudited)

history of generating underwriting profits from the policies it writes, in addition to earning additional income from its investment portfolio. We believe the company’s competitive position is strong and that management is a reasonably good steward of capital. Throughout most of the period, the position was a strong contributor. However, it fell toward the end of the period as the market focused on credit and economic concerns. Our view is that Nipponkoa will emerge relatively unharmed from the current U.S.-centric problems. We believe that the compelling valuation and expected return should compensate us for the modest balance sheet risk.

Syngenta A.G., the Swiss agrichemical company, continued to benefit from strong markets for its insecticides, pesticides and specialized seeds. Also, the company reported results that showed double-digit revenue growth and margin expansion. Although we are monitoring valuation, we believe that this company should have a relatively modest correlation with economic cycles.

Outlook

Looking ahead, we will be paying close attention to the U.S. employment picture, the availability of credit, U.S. consumer confidence and commodity prices, among other things. Should the U.S. labor market continue to soften amid continued weakness in the U.S. housing market, further slowing in U.S. consumer spending is likely. While the government stimulus checks could provide a temporary boost, the current de-leveraging of the U.S. economy could take time to complete, possibly lessening the potential for a sharp rebound in economic activity. Inflation remains a concern for the markets as well, given record commodity prices and its recent elevated level in many regions. Although inflation is generally a lagging indicator and should ease with slowing economic growth, it deserves attention given its negative impact on equity valuations and influence on central bank policy decisions.

While economic activity in the U.S. and other developed parts of the world appears to be slowing, the global economy continues to expand. We will continue to monitor the potential for further slowing in the U.S. and other large economies and the impact this could have on the rest of the global economy. Nevertheless, we remain committed to our fundamental investment approach in our effort to find opportunities that we believe represent an attractive risk/reward profile. As always, we will continue to emphasize bottom-up company analysis as our primary tool in our quest to add value for shareholders.

Thank you for your investment in Janus Global Opportunities Fund.

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.

A 2% redemption fee may be imposed on shares held for 90 days or less. Performance shown does not reflect this redemption fee and, if reflected, performance would have been lower.

The fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2007. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.) All expenses are shown without the effect of expense offset arrangements.

The Fund’s performance may be affected by risks that include those associated with non-diversification, 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 (“IPOs”),and derivatives. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the fund, and therefore a fund’s performance, may decline in response to such risks.

Returns include reinvestment of dividends from net investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

June 30, 2001 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.

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.

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 unmanaged and are not available for direct investment; therefore their performance does not reflect the expenses associated with the active management of an actual portfolio.

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, 2008, Janus Global Research Fund returned (6.37)%, ourperforming its primary benchmark, the Morgan Stanley Capital International (MSCI) World Growth Index, which returned (7.51)% and its secondary benchmark, the Russell 1000^® Index, which returned (9.54)%.

Economic Overview

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. and global economies and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and world equity markets finished well above the mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008.

Overall, emerging market stocks in Latin America were among the biggest winners during the period amid continued strength in commodity prices. Developing markets in Asia were weak, with China suffering a sharp decline on worries over slowing export growth. In local currency terms, developed non-U.S. markets underperformed both emerging markets and U.S. stocks. The U.S. dollar weakened versus most major currencies for much of the period as concern over economic growth and a more accommodative Federal Reserve helped to fuel the negative sentiment toward it.

Following the March lows, the equity markets’ rally at the end of the period can be attributed in part to improving sentiment as investors began to look ahead to a possible economic recovery in the U.S. Nevertheless, concerns about elevated inflationary pressures, soft U.S. consumer spending, the weak U.S. housing market and the lingering possibility of more write-downs, continued to weigh on the market. By focusing on deeply researching our investments and maintaining a long term perspective, we were able to outperform the Fund’s benchmark indices for the period. The Fund uses the best stock picks from Janus’ more than 30 research analysts, with similar sector and non-U.S. weights as the Fund’s primary benchmark. Director of Research, Jim Goff, oversees the seven global sector teams and each team discusses ideas among team members to choose what they believe are the best for inclusion in the Fund. The result is a diversified portfolio of well-researched, high-conviction ideas. As of April 30, 2008, the Fund held 115 stocks with the top 10 securities representing 21% of the Fund’s net assets.

Contributors to Fund Performance

Leading the Fund’s performance was fertilizer company Potash Corporation of Saskatchewan. The company produces potash, nitrogen and phosphate, all three important components of fertilizers. We bought Potash because of a long-term bullish view on demand for agricultural products and we believe that the company will benefit from rising prices for potash as supply for this commodity struggles to keep pace with demand. We continue to see a super-cycle among agricultural commodities and related products, such as potash, for which the Canadian company is the world’s largest supplier.

Syngenta, the Swiss agrichemical company, reported results that showed double-digit revenue growth and margin expansion. The company, which produces agrichemicals and specialized seeds, also benefited from the strong agricultural cycle. Long term, we think that the company’s products will help alleviate tight conditions in agricultural commodities by contributing to the increase in yield. As with Potash, Syngenta provided some buffer against the most recent economic cycle.

Detractors from Fund Performance

In terms of country exposure, our holdings in China and the United Kingdom were the primary detractors. The Fund’s top individual detractor was Shanghai Electric Group. This industrial company involved in infrastructure equipment and projects in China fell among weakness in the Chinese market and on some concern about the pace of infrastructure investment in China. However, we continue to believe there is long-term value in this name.

SiRF Technology Holdings, another detractor during the period, is a supplier of semiconductors used in global positioning systems. It declined after reporting weaker-than-expected margins in its most recent quarter. The eroding margins suggested to us that the company’s competitive positioning was weaker than first thought. We chose to exit the position.

Outlook

The Fund remains sector-neutral and we expect stock selection to be a key driver of returns going forward. Volatile markets tend to give many investors a reason to focus on the short term. Therefore, we believe we will see many opportunities for long-term investors to purchase good businesses at attractive prices. Looking ahead, we will continue to invest with conviction in areas where we feel we can develop an edge through research. Through our valuation discipline and focus on risk management, we remain committed to delivering superior long-term results for our clients.

Thank you for your investment in Janus Global Research Fund.

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.

A 2% redemption fee may be imposed on shares held for 90 days or less. Performance shown does not reflect this redemption fee and, if reflected, performance would have been lower.

Janus Capital has contractually agreed to waive the Fund’s total operating expenses (excluding brokerage commissions, interest, dividends, taxes, and extraordinary expenses including, but not limited to, acquired fund fees and expenses) to a certain limit until at least March 1, 2009. The expense waiver shown reflects the application of such limit and is detailed in the Statement of Additional Information. Returns shown include fee waivers, if any, and without such waivers, the Fund’s returns would have been lower.

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

The fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2007. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.) Contractual waivers agreed to by Janus Capital, where applicable, are included in the prospectus 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. The Fund’s total operating expenses did not exceed the expense limit so no waivers were in effect for the most recent period presented.

See important disclosures on the next page.

The Fund’s performance may be affected by risks that include those associated with 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 (“IPOs”) and derivatives. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and other details.

The Fund invests in Real Estate Investment Trusts (REITs) which may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: legal, political, liquidity, and interest rate risks, a decline in the value of real estate, risks related to economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Fund invests in foreign REITs, the Fund may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the fund, and therefore a fund’s performance, may decline in response to such risks.

Returns include reinvestment of dividends from net investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

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.

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 January 1, 2007, Janus Global Research Fund compares its performance to the MSCI World Growth Index, and such benchmark index is used to calculate the Fund’s performance-based adjustment to the investment advisory fee for periods after January 1, 2007.

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 unmanaged and are not available for direct investment; therefore their performance does not reflect the expenses associated with the active management of an actual portfolio.

See “Explanations of Charts, Tables and Financial Statements.”

Janus Overseas Fund (unaudited) (closed to new investors) Ticker: JAOSX

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

Janus Overseas Fund returned (4.20)% over the six-month period ended April 30, 2008. The Fund’s primary benchmark, the Morgan Stanley Capital International (MSCI) EAFE^® Index returned (9.21)%, and its secondary benchmark, the MSCI All Country World ex-U.S. Index^SM, returned (9.34)% during the period.

Economic Overview

The global credit crisis, fears of a U.S. and global economic slowdown, rising oil and commodity prices and inflationary pressures created a difficult market environment over the past six months. Although world equity markets finished above the mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008.

Energy and commodity stocks were among the biggest winners during the period driven by a strong commodity price environment. Financial and consumer discretionary stocks suffered as a result of the credit crisis and the weakening economic outlook. During the period, most major developed and emerging markets performed poorly. Also, the U.S. dollar weakened versus most major currencies.

Stocks That Aided Performance

The top three contributors to Fund performance during the period were agriculture companies K+S A.G., Potash Corporation of Saskatchewan and Chaoda Modern Agriculture Holdings. Fertilizer companies, German based K+S and Canada based Potash Corporation, benefited from price increases and strong volume growth for potash fertilizer. Rising crop prices, driven by demand growth from emerging economies and from ethanol, combined with limited global supply growth in potash created a favorable environment for potash producers. Although I continue to believe that fundamentals remain strong for K+S and Potash Corporation, I reduced positions in both companies during the period based on valuation. Chinese vegetable producer Chaoda performed well as the company continued to successfully acquire land and grow its vegetable production base. The company is also a potential beneficiary of rising food prices in China.

Stocks That Hindered Performance

Arcandor A.G., a German conglomerate with department store, travel, and mail order businesses, was the largest detractor during the period. The stock was hurt due to concerns about the impact of an economic slowdown on its consumer related businesses and concerns that the company’s ambitious restructuring plans would be stalled by the credit crisis. I believe that the benefits of the company’s restructuring program were not fully appreciated by the market, and I held onto the position during the period.

ARM Holdings, a U.K. semiconductor intellectual property company, fell as a result of disappointing earnings and concerns about the impact of an economic slowdown on its business. I continue to believe that ARM remains well positioned to benefit from the growth in semiconductors across a wide variety of applications. The company is a particular beneficiary of growth in more complex wireless devices like the iPhone.

Outlook

In a volatile market environment, the conviction to hold onto existing positions or buy new ones is critical. My conviction comes from the tremendous in-depth research our analyst team conducts on a daily basis.

The markets have been difficult over the past six months, and they may remain difficult for some time. Throughout turbulent markets, I have not changed my investment approach. I believe the best way to generate solid 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 sole focus is to deliver strong, long-term performance for you. I will perform this job to the best of my ability.

Thank you for your continued investment in Janus Overseas Fund.

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.

A 2% redemption fee may be imposed on shares held for 90 days or less. Performance shown does not reflect this redemption fee and, if reflected, performance would have been lower.

The fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2007. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.) 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.

Janus Overseas Fund (unaudited)

The Fund’s performance may be affected by risks that include those associated with 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 (“IPOs”) and derivatives. Please see a Janus prospectus or www.janus.com for more information about risks, portfolio holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the fund, and therefore a fund’s performance, may decline in response to such risks.

Janus Overseas Fund held approximately 12.7% of its assets in Brazilian securities as of April 30, 2008 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.

Returns include reinvestment of dividends from net investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

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.

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 unmanaged and are not available for direct investment; therefore their performance does not reflect the expenses associated with the active management of an actual portfolio.

See “Explanations of Charts, Tables and Financial Statements.”

Fund Snapshot

This global fund offers geographic diversification in a single portfolio.

Performance Overview

Janus Worldwide Fund returned (13.57)% over the six-month period ended April 30, 2008, underperforming its benchmark, the Morgan Stanley Capital International (MSCI) World Index^SM, which returned (9.37)% during the period.

Economic Overview

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. and global economies and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and world equity markets finished well above the mid-March lows, stocks were broadly lower during the six-month period ended April 30, 2008.

Additional subprime-related write-offs, slowing U.S. consumer spending and a softening U.S. labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the credit markets. World markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept and played an instrumental role in JP Morgan Chase’s purchase of Bear Stearns.

Overall, emerging market stocks in Latin America were among the biggest winners during the period amid continued strength in commodity prices. Developing markets in Asia were weak, with China suffering a sharp decline on worries over slowing export growth. In local currency terms, developed non-U.S. markets underperformed both emerging markets and U.S. stocks. The U.S. dollar weakened versus most major currencies for much of the period as concern over economic growth and a more accommodative Fed helped to fuel the negative sentiment toward it. Losses were broad across all sectors. Energy and materials were the only sectors to turn in a gain for the six-month period as the price of oil and other commodities soared. Meanwhile, financials and consumer discretionary stocks were the worst performing groups, suffering from turmoil in the credit markets, larger-than-expected subprime-related write-downs and a weakening economic outlook.

Following the March lows, the equity markets’ rally at the end of the period can be attributed in part to improving sentiment as investors began to look ahead to a possible economic recovery in the U.S. Nevertheless, concerns about elevated inflationary pressures, soft U.S. consumer spending, the weak U.S. housing market and the lingering possibility of more write-downs, continued to weigh on the market.

Stocks That Hindered Performance

The largest detractor from performance during the period was Dell. Worries over Dell’s exposure to the U.S. economy, and more importantly questions about their ability to succeed in their turnaround efforts weighed on the shares. I continue to believe Dell is a highly attractive investment, given its numerous competitive strengths, proven track record of high economic profitability and very well-capitalized balance sheet. Additionally I consider management, who are sizable owners themselves, to be highly capable. I think the company has a number of opportunistic initiatives in place which can improve business results over the coming years.

British Sky Broadcasting Group was another detractor during the period following a weaker-than-expected earnings report. The U.K.-based pay-television broadcaster’s new broadband and telephone business showed higher costs and lower subscriber growth than most were expecting. I believe that the company’s core satellite broadcasting business represents a highly cash generative, non-cyclical business with potential for good revenue growth and expanding margins.

Stocks That Aided Performance

The top contributor to performance during the period was Potash Corporation of Saskatchewan. The company produces potash, nitrogen and phosphate, all three important components of fertilizers. Potash Corporation rose nearly 50% amid tight potash supply conditions and strong demand for these key ingredients used in fertilizer. I trimmed this position as the valuation rose.

Syngenta A.G., the Swiss agrichemical company, reported results that showed double-digit revenue growth and margin expansion. This stock has benefited from robust markets for agricultural commodities and related products. Although the market fundamentals remain strong in the

30  Janus International and Global Funds  April 30, 2008

(unaudited)

agricultural related industries, I am carefully reviewing the valuations after such strong performance.

Outlook

Looking ahead, I will be paying close attention to the U.S. employment picture, the availability of credit, U.S. consumer confidence and commodity prices, among other things. Should the U.S. labor market continue to soften amid continued weakness in the U.S. housing market, further slowing in U.S. consumer spending is likely. While the government stimulus checks could provide a temporary boost, the current de-leveraging of the U.S. economy could take time to complete, possibly lessening the potential for a sharp rebound in economic activity. Inflation remains a concern for the markets as well, given record commodity prices and its recent elevated level in many regions. Although inflation is generally a lagging indicator and should ease with slowing economic growth, it deserves attention given its negative impact on equity valuations and influence on central bank policy decisions.

While economic activity in the U.S. and other developed parts of the world appears to be slowing, the global economy continues to expand. I will continue to monitor the potential for further slowing in the U.S. and other large economies and the impact this could have on the rest of the global economy. Nevertheless, I remain committed to my fundamental investment approach in my effort to find opportunities that I believe represent an attractive risk/reward profile. As always, I will continue to emphasize bottom-up company analysis as my primary tool in my quest to add value for shareholders.

Thank you for your investment in Janus Worldwide Fund.

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.

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 the performance of the Fund’s primary benchmark index for that period.

A 2% redemption fee may be imposed on shares held for 90 days or less. Performance shown does not reflect this redemption fee and, if reflected, performance would have been lower.

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

The fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2007. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.) 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 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 (“IPOs”), and derivatives. Please see a Janus prospectus or www.janus.com for more information about risks, fund holdings and other details.

Foreign securities have additional risks including exchange rate changes, political and economic upheaval, the relative lack of information, relatively low market liquidity and the potential lack of strict financial and accounting controls and standards. These risks are magnified in emerging markets. The prices of foreign securities held by the fund, and therefore a fund’s performance, may decline in response to such risks.

Returns include reinvestment of dividends from net investment income and distributions from 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

May 16, 1991 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.

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.

The Fund’s portfolio may differ significantly from the securities held in the index. The index is unmanaged and is not available for direct investment; therefore its performance does not reflect the expenses associated with the active management of an actual portfolio.

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 Global Opportunities Fund, Janus Global Research Fund, Janus Overseas Fund and Janus Worldwide Fund (collectively the “Funds” and individually a “Fund”) are series funds. The Funds are part of Janus Investment Fund (the “Trust”), which is 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 twenty-nine funds. The Funds invest primarily in equity securities. Each Fund in this report is classified as diversified as defined in the 1940 Act, with the exception of Janus Global Opportunities Fund, which is 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.

Effective December 21, 2007, Janus Overseas Fund was closed to new investors. Current investors may continue to invest in the Fund, as well as reinvest any dividends or capital gains distributions. However, once an account is closed, additional investments in the Fund will not be accepted unless you meet certain criteria.

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. Circumstances in which fair value pricing may be utilized include, but are not limited to: (i) when significant events occur which may affect the securities of a single issuer, such as mergers, bankruptcies, or significant issuer specific developments; (ii) when significant events occur which may affect an entire market, such as natural disasters or significant governmental actions; and (iii) when non-significant events occur such as markets closing early or not opening, security trading halts, or pricing of non-valued securities and restricted or non-public securities. 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. Dividends from foreign securities may be subject to withholding taxes in foreign 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 Fund 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. 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 if time permits. All loans will be continuously secured by collateral which may consist of cash,

46  Janus International and Global Funds  April 30, 2008

U.S. Government securities, domestic and foreign short-term debt instruments, letters of credit, time deposits, repurchase agreements, money market mutual funds or other money market accounts, or such other collateral permitted by the Securities and Exchange Commission (“SEC”).

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 loaned securities at the close of business, employing the most recent available pricing information. Collateral levels are then adjusted based upon this mark-to-market evaluation.

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

Interfund Lending

Pursuant to an exemptive order received from the SEC, each Fund may be party to interfund lending agreements between the Fund 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 the borrowing Funds’ 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 Funds may enter into forward currency contracts in order to reduce exposure to changes in foreign currency exchange rates on 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 investment and 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.

Futures Contracts

The Funds may enter into futures contracts to gain exposure to the stock market pending investment of cash balances or to meet liquidity needs. The Funds may also 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 values of the contracts and the underlying securities, or that the counterparty will fail to perform its obligations.

Janus International and Global Funds  April 30, 2008  47

Notes to Financial Statements (unaudited) (continued)

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 as “Net realized gain/(loss) from futures contracts” 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.

Swaps

The Funds may enter into swap agreements to hedge exposure to interest rates and credit risk or for investment purposes. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. Swap contracts are reported as an asset and liability on the Statement of Assets and Liabilities. Realized gains and losses are reported in “Net realized gain/(loss) from swap contracts” on the Statement of Operations (if applicable).

Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the swap contract. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Funds, and/or the termination value. Therefore, the Funds consider the creditworthiness of each counterparty to a swap contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities.

Options Contracts

The Funds may purchase or write put and call options on futures contracts and on portfolio securities for hedging purposes or as a substitute for an investment. The Funds may also purchase or write put and call options on foreign currencies in a manner similar to that in which futures or forward contracts on foreign currencies will be utilized. The Funds may also invest in Long-Term Equity Anticipation Securities (LEAPS), which are long-term option contracts that can be maintained for a period of up to three years. The Funds generally invest in options to hedge against adverse movements in the value of portfolio holdings.

When an option is written, the 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 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 Funds could result in the Funds 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 are adjusted by the amount of premium received or paid.

The Funds may also purchase and write exchange-listed and over-the-counter put and call options on domestic securities indices, and on foreign securities indices listed on domestic and foreign securities exchanges. Options on securities indices are similar to options on securities except that (1) the expiration cycles of securities index options are monthly, while those of securities options are currently quarterly, and (2) the delivery requirements are different. Instead of giving the right to take or make delivery of securities at a specified price, an option on a securities index gives the holder the right to receive a cash “exercise settlement amount” equal to (a) the amount, if any, by which the fixed exercise price of the option exceeds (in the case of a put) or is less than (in the case of a call) the closing value of the underlying index on the date of exercise, multiplied by (b) a fixed “index multiplier.” Receipt of this cash amount will depend upon the closing level of the securities index upon which the option is based being greater than, in the case of a call, or less than, in the case of a put, the exercise price of the index and the exercise price of the option times a specified multiple. The writer of the option is obligated, in return for the premium received, to make delivery of this amount.

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 as “Options written at value” (if applicable).

Realized gains and losses are reported as “Net realized gain/(loss) from options contracts” on the Statement of Operations (if applicable).

The risk in writing call options is that the Funds give up the opportunity for profit if the market price of the security increases and the option is exercised. The risk in writing put options is that the Funds may incur a loss if the market price of the security decreases and the option is exercised. The risk in buying options is that the 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 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 Funds’ hedging strategy unsuccessful. In addition, there can be no assurance that a liquid secondary market will exist for any option purchased or

48  Janus International and Global Funds  April 30, 2008

sold. There is no limit to the loss the Funds may recognize due to written call options.

Short Sales

The Funds may engage in “short sales against the box.” Short sales against the box involve either selling short a security that the Funds own, or selling short a security that the Funds have the right to obtain, for delivery at a specified date in the future. The Funds may enter into short sales against the box to hedge against anticipated declines in the market price of portfolio securities. The Funds do not deliver from their portfolios the securities sold short and do not immediately receive the proceeds of the short sale. The Funds borrow the securities sold short and receive proceeds from the short sale only when they deliver the securities to the lender. If the value of the securities sold short increases prior to the scheduled delivery date, the Funds lose the opportunity to participate in the gain.

The Funds may also engage in other short sales. The Funds may engage in short sales when the portfolio managers and/or investment personnel anticipate that a security’s market purchase price will be less than its borrowing price. To complete the transaction, the Funds must borrow the security to deliver it to the purchaser and buy that same security in the market to return it to the lender. The total market value of all of a Fund’s short sales positions, other than against the box, will not exceed 10% of its net assets. Although the potential for gain as a result of a short sale is limited to the price at which the Fund sold the security short less the cost of borrowing the security, the 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 to the size of any loss that the Fund may recognize upon termination of a short sale. Short sales held by the Funds are fully collateralized by other securities, which are denoted in the accompanying Schedule of Investments (if applicable).

Foreign Currency Translations

The Funds do not isolate that portion of the results of operations resulting from the effect of 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. Unrealized net appreciation or depreciation of investments and foreign currency translations arises 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 foreign 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.

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 Funds may hold liquid assets as collateral with the Funds custodian sufficient to cover the purchase price.

Exchange-Traded Funds

The Funds may invest in exchange-traded funds, which are index-based investment companies that hold substantially all of their assets in securities representing their specific index. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operations.

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 non-registered 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.

Notes to Financial Statements (unaudited) (continued)

Restricted Cash

As of April 30, 2008, Janus Global Research Fund had restricted cash in the amount of $160,000. The restricted cash represents funds in relation to swap contracts invested by the Funds as of April 30, 2008. 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.

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 the Funds may not be sold except in exempt transactions or in a public offering registered under the Securities Act of 1933, as amended. 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 the Funds 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

Each Fund generally declares and distributes dividends of net investment income and realized 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.

The Funds may make certain investments in real estate investment trusts (“REITs”) which pay dividends to their shareholders based upon funds available from operations. It is quite common for these dividends to exceed the REIT’s taxable earnings and profits, resulting in the excess portion of such dividends being designated as a return of capital. If the Funds distribute such amounts, such distributions could constitute a return of capital to shareholders for federal income tax purposes.

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.

The Funds adopted the provisions of Financial Accounting Standards Board (“FASB”) Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes on April 30, 2008. FIN 48 requires an evaluation of tax positions taken (or expected to be taken) in the course of preparing a Fund’s tax return to determine whether these positions meet a “more-likely-than-not” standard that based on the technical merits have a more than fifty percent likelihood of being sustained by a taxing authority upon examination. A tax position that meets the “more-likely-than-not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations.

FIN 48 requires management of the Funds to analyze all open tax years, fiscal years 2003 - 2006 as defined by Statute of Limitations, for all major jurisdictions, including federal tax authorities and certain state tax authorities. As of and during the six-month period ended April 30, 2008, the Funds did not have a liability for any unrecognized tax benefits. The Funds have no examination in progress and are not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

New Accounting Pronouncements

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS No. 157”), which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS No. 157 does not require new fair value measurements, but is applied to the extent that other accounting pronouncements require or permit fair value measurements. SFAS No. 157 emphasizes that fair value is a market-based measurement that should be determined based on the assumptions that market participants would use in pricing an asset or liability. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. Management does not believe the adoption of SFAS No. 157 will impact the financial statement amounts; however, the Funds will be required to disclose the extent to which fair value is used to measure assets and liabilities and the inputs used to develop the measurements.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for

50  Janus International and Global Funds  April 30, 2008

Financial Assets and Financial Liabilities” (“SFAS No. 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. SFAS No. 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. SFAS No. 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. Management does not believe the adoption of SFAS No. 159 will impact the financial statement amounts.

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS No. 161”), which requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. SFAS No. 161 is effective for financial statements issued for fiscal years beginning after November 15, 2008, and interim periods within those fiscal years. Management is in the process of evaluating the impact of SFAS No. 161 on the Funds’ financial statement disclosures.

2.  Investment Advisory Agreements and Other Transactions with Affiliates

The Funds pay 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	Advisory Fee %
Janus Global Opportunities Fund		0.64%
Janus Global Research Fund		0.64%
Janus Overseas Fund		0.64%
Janus Worldwide Fund		0.60%

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 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 Global Research Fund		MSCI World Growth Index
Janus Worldwide Fund		MSCI World IndexSM

Any performance adjustment commenced on January 1, 2007 for Janus Global Research Fund and February 1, 2007 for Janus Worldwide Fund, prior to which only the base fee rate applied. Only the base fee rate will apply 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 the Funds 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. 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 index is 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 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 performance relative 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

Janus International and Global Funds  April 30, 2008  51

Notes to Financial Statements (unaudited) (continued)

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 contain 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. During the six-month period ended April 30, 2008, the Funds recorded the following Performance Adjustment as indicated in the table below:

	Performance
Fund	Fee
Janus Global Research	$	109,619
Janus Worldwide		467,015

Until at least March 1, 2009, 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 the Fund’s normal operating expenses in any fiscal year, including the investment advisory fee, but excluding brokerage commissions, interest, taxes and extraordinary expenses, (including, but not limited to, acquired fund fees and 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.

The Funds’ expenses may be reduced by expense offsets from an unaffiliated custodian and/or transfer agent. Such credits or offsets are included in “Expense and Fee Offset” 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.

Each Fund pays Janus Services LLC (“Janus Services”), a wholly-owned subsidiary of Janus Capital and the Funds’ transfer agent, 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 from each of the Funds excluding Janus Overseas Fund for transfer agent services.

During the six-month period ended April 30, 2008, Janus Services reimbursed the following Funds as a result of dilutions caused by incorrectly processed shareholder activity as indicated in the table below:

Fund
Janus Global Opportunities Fund	$	1,847
Janus Global Research Fund		5,647
Janus Overseas Fund		53,663

During the fiscal year ended October 31, 2007, Janus Services reimbursed the following Fund as a result of dilutions caused by incorrectly processed shareholder activity as indicated in the table below:

Fund
Janus Global Opportunities Fund	$	3
Janus Overseas Fund		9,628

During the fiscal year ended October 31, 2007, Janus Capital reimbursed the following Funds as a result of dilutions caused by certain trading and/or pricing errors as indicated in the table below:

Fund
Janus Global Research Fund	–(1)

(1) Amounts reimbursed were less than a dollar.

For the six-month period ended April 30, 2008, Janus Capital assumed $16,904 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 the Pending Legal Matters. 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 the Funds that commenced operations after July 31, 2004. As a result, no fees were allocated to Janus Global Research Fund. Additionally, all future non-recurring costs will be allocated to the 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 Board of Trustees has adopted a deferred compensation plan (the “Deferred 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

52  Janus International and Global Funds  April 30, 2008

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 are credited to the account. The fluctuation of the account balance is recorded by the Funds as unrealized appreciation/(depreciation) and is shown as of April 30, 2008 on the Statement of Assets and Liabilities as an asset, “Non-interested Trustees’ deferred compensation,” and a liability, “Non-interested Trustees’ deferred compensation fees.” Additionally, the recorded unrealized appreciation/(depreciation) is included in “Unrealized net appreciation/(depreciation) of investments, foreign currency translations and non-interested Trustees’ deferred compensation” on the Statement of Assets and Liabilities. Deferred compensation expenses for the six-month period ended April 30, 2008 are included in “Non-interested Trustees’ fees and expenses” on the Statement of Operations. Trustees are allowed to change their designation of mutual funds from time to time. Amounts will be deferred until distributed in accordance with the Deferred Plan. No deferred fees were paid to any Trustee under the Deferred Plan during the six-month period ended April 30, 2008.

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 Trust. Total compensation of $39,907 was paid by the Trust during the six-month period ended April 30, 2008. Each Fund’s portion is reported as part of “Other Expenses” on the Statement of Operations.

A 2.00% redemption fee may be imposed on shares of Janus Global Opportunities Fund, Janus Global Research Fund, Janus Overseas Fund and Janus Worldwide 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 the Funds for the six-month period ended April 30, 2008 are indicated in the table below:

Fund	Redemption Fee
Janus Global Opportunities Fund	$	107,500
Janus Global Research Fund		118,645
Janus Overseas Fund		2,077,767
Janus Worldwide Fund		110,491

The Funds may invest in money market funds, including funds managed by Janus Capital. During the six-month period ended April 30, 2008, the following Funds recorded distributions from affiliated investment companies as affiliated dividend income, and had the following affiliated purchases and sales:

Income and capital gains distributions are determined in accordance with income tax regulations that may differ from accounting principles generally accepted in the United States of America. These differences are due to differing treatments for items such as net short-term gains, deferral of wash sale losses, foreign currency transactions, net investment losses and capital loss carryovers.

The Funds have elected to treat gains and losses on forward foreign currency contracts as capital gains and losses. Other foreign currency gains and losses on debt instruments are treated as ordinary income for federal income tax purposes pursuant to Section 988 of the Internal Revenue Code.

The aggregate cost of investments and the composition of unrealized appreciation and depreciation of investment securities for federal income tax purposes as of April 30, 2008 are noted below.

Unrealized appreciation and unrealized depreciation in the table below exclude appreciation/depreciation on foreign currency translations. The primary difference between book and tax appreciation or depreciation of investments are wash sale loss deferrals and passive foreign investment companies.

	Federal Tax		Unrealized		Unrealized		Net Tax
Fund	Cost		Appreciation		(Depreciation)		Appreciation
Janus Global Opportunities Fund	$	135,114,326	$	27,433,390	$	(11,107,921)	$	16,325,469

6.  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 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. The appeal is still pending and argument in the matter was held in December 2007. 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. However, in June 2007, Plaintiffs appealed that dismissal to the United States Court of Appeals for the Fourth Circuit. That appeal is currently pending.

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 status conference was held on June 28, 2007, during which the parties were ordered to submit their proposed scheduling order. To date, no scheduling order has been entered in the case. In addition to the pending Motion to Discharge Order to Show Cause, 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.

During 2007, two lawsuits were filed against Janus Management Holdings Corporation (“Janus Holdings”), an affiliate of JCGI, by former Janus portfolio managers, alleging that Janus Holdings unilaterally implemented certain changes to compensation in violation of prior agreements. These complaints allege some or all of the following claims: (1) breach of contract; (2) willful and wanton breach of contract; (3) breach of good faith and fair dealing; and (4) estoppel. Janus Holdings filed Answers to these complaints denying any liability for these claims and intends to vigorously defend against the allegations.

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, none of whom has ever been affiliated with Janus Capital (“Independent Trustees”), oversee the management of each Fund 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 Fund, 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 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 with management to consider the agreements, and also met separately in executive session with their independent legal counsel and their independent fee consultant.

At a meeting held on December 14, 2007, based on their evaluation of the information provided by Janus Capital, the subadvisers and the independent fee consultant, as well as other information, the Trustees determined that the overall arrangements between each Fund and Janus Capital and each subadviser, as applicable, 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 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, 2008 through February 1, 2009 (January 1, 2008 through January 1, 2009 for INTECH Risk-Managed Stock Fund and Janus Global Research Fund), subject to earlier termination as provided for 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, the knowledge of 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 and/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 those 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

56  Janus International and Global Funds  April 30, 2008

appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract well-qualified personnel.

Performance of the Funds

The Trustees considered the investment performance 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 many 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 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, 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.

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 fee rates for Funds having a similar strategy, the Trustees noted that, under the terms of 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, the Trustees 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.

The Trustees reviewed information on the profitability to Janus Capital and its affiliates of their relationships with each Fund, as well as an explanation of the methodology used in allocating various expenses of Janus Capital and its affiliates among the Funds and other clients. They 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 receives adequate incentives to manage the Funds effectively. They 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 adviser, 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 payable by Janus Capital or the Funds to the subadvisers of subadvised Funds, were reasonable in relation to the nature, extent 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 subadvisers charge to other clients. They 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, those Funds benefited from having advisory fee rates that remained constant rather than increasing as assets declined. In addition, performance fee structures have been

Additional Information (unaudited) (continued)

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. They also considered Janus Capital’s past and proposed use of commissions paid by Funds on their portfolio brokerage transactions to obtain proprietary and third-party research products and services benefiting those Funds and/or other clients of Janus Capital. The Trustees concluded that Janus Capital’s use of “soft” commission dollars of a Fund to obtain proprietary and third-party 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 also concluded that Janus Capital benefits from the receipt of proprietary and third-party 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, all of whom are 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.

Explanations of Charts, Tables and
Financial Statements (unaudited)

1.  Performance Overviews

Performance overview graphs compare the performance of a hypothetical $10,000 investment in each Fund (from inception) 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 dividends and distributions, 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, 2007. 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 written options contracts follows each Fund’s Schedule of Investments (if applicable). Written options 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 will 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 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 and expense reimbursements, if any, are also shown.

The last section lists the increase or decrease in the value of securities held in the Funds. The 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 Funds’ 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 will 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 withdrawals via redemptions. “Redemption Fees” (if applicable) refers to the fee paid to the Funds for shares held for 90 days 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 each Fund’s net asset value (“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 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 frequency of dividend payments 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 the offset and the net expenses. The

60  Janus International and Global Funds  April 30, 2008

expense ratios listed in the Financial Highlights reflect total expenses prior to any expense offset (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 size asset 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.

Janus provides access to a wide range of investment disciplines.

Asset Allocation

Janus asset allocation portfolios 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.

Co-Chief Investment Officers’ Letter to the Shareholders

Jonathan Coleman

Co-Chief Investment

Officer

Gibson Smith

Co-Chief Investment

Officer

Dear Shareholders,

Challenging economic conditions have been the dominant theme for the financial markets over the past several months. Despite recent volatility, our investment team has maintained a relentless focus on our fundamental, bottom-up research process and has continued to discover compelling investment opportunities for our shareholders.

Major Market Themes

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above their mid-March lows, stocks were broadly lower over the six months ended April 30, 2008. The Russell 1000^® Index declined 9.54%, the Russell 2000^® Index was down 12.92% and the Morgan Stanley Capital International (MSCI) All Country World Index^SM gave up 9.47% during the period. Fixed-income markets proved to be volatile over the period with the Lehman Brothers Aggregate Bond Index up 4.08% and the Lehman Brothers High-Yield Bond Index lost 0.74% over the period.

Additional write-offs related to the loose lending practices over the previous 36 months, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Uncertain market conditions resulted in interest rates hitting five-year lows with the 10-Year Treasury Note touching 3.33%. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the funding and credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept, allowed for broker/dealers to borrow directly from the Fed and played an instrumental role in JP Morgan Chase’s purchase of near-defunct Bear Stearns. All of these moves were vitally important toward stabilizing the financial system while allowing for the recovery process to continue. By the end, the Fed had lowered its target interest rate from 4.50% to 2.00% during the period.

Following the March lows, the equity market’s rally at the end of the six-month period can be attributed to the moves by the Fed and, in part, to improving sentiment as investors began to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs continued to weigh on the market.

Performance Notables

For the one-year period ended April 30, 2008, 77% of Janus’ retail funds ranked within Lipper’s top two quartiles, based upon total returns. The results were even stronger over longer time periods as 87% of our retail funds achieved first- or second-quartile Lipper rankings over three years and 86% ranked in Lipper’s top two quartiles over five years. Furthermore, 78.3% of our retail funds had a 4- or 5-star overall Morningstar Rating^tm as of April 30, 2008, well ahead of the 32.5% of funds for which Morningstar awards 4- or 5-stars in each category. (See complete Lipper rankings on page 3 and complete Morningstar Ratings^tm on page 4).

Investment Team Update

We continue to enhance the breadth of our global stock coverage and work tirelessly to generate solid investment insights in an attempt to deliver superior investment performance. Our hands-on research approach is critical to our stock selection process. As such, the Janus equity research team traveled over 2.9 million miles in 2007 investigating potential stock and bond picks worldwide. This year, we plan to embark on a multi-year strategy to locate certain investment personnel closer to the companies that they research as an important first step in building out our global footprint from a research standpoint.

While our objective is to develop a research edge and invest with conviction in our funds, we seek to do so in a disciplined and thoughtful way by clearly understanding and managing risk in our portfolios. Dan Scherman, Director of Risk and Trading, works continually with our investment management

team to ensure that portfolio risks are intentional and calculated. We believe this analysis is both timely and critical as we navigate today’s challenging markets.

Conclusion

As we look back over the past six months, we are relieved that signs of stabilization appeared in the financial markets as the period came to a close. However, we recognize that there are still significant challenges ahead. Increasing risk aversion has resulted in a significant contraction of credit availability for both consumers and corporations. The tightening of credit, along with declining real estate prices, rising energy prices and a climbing unemployment rate may all create significant economic headwinds in the near future. While unsettling, we believe this is a natural and necessary process of recovery from the excessive risk-taking and loose lending standards that developed over the previous several years in many areas of the credit markets. We feel that the environment will improve as the healing process progresses.

So, as we look ahead, we are paying very close attention to the outlook for the global economy, with a keen focus on slowing growth in the United States and the growth rates of the emerging economies around the globe. As these emerging economies become more prosperous, they may be able to move from economies based exclusively on exports fueling their growth to more balanced models emphasizing both exports and internal consumption of the goods they produce. Over a longer period of time, we believe this creates more stability in the global economy. We are also watching rising energy and commodity prices and their impact on inflationary expectations and the absolute level of interest rates. In addition to interest rates, we are focused on the outlook for the housing market and the implications of changes in home prices on the underlying health of the financial system, believing that the recapitalization of the banking and brokerage sectors is a vitally important element of the healing process.

While market volatility is undoubtedly challenging, it can also create an environment that can result in incredibly compelling investment opportunities. Our top priority is to remain committed to our process of in-depth fundamental research, which has been at the core of our investment process since Janus’ inception in 1969. With this singular focus we strive to deliver consistent long-term results for our shareholders.

Thank you for your continued investment in Janus funds.

Sincerely,

Jonathan Coleman

Data presented reflects past performance, which is no guarantee of future results.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating^TM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of the funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variation in the distribution percentages.)

Useful Information About Your Fund Report

Management Commentaries

The Management Commentaries in this report include valuable insight from each of 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, 2008. As the investing environment changes, so could the managers’ 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 upon an investment of $1,000 invested at the beginning of the period and held for the six-month period from November 1, 2007 to April 30, 2008.

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 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 each Bond Fund’s total operating expenses, excluding brokerage commissions, interest, dividends, taxes and extraordinary expenses including, but not limited to, acquired fund fees and expenses, to certain limits until at least March 1, 2009. 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.

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).

Performance Overview

During the six-month period ended April 30, 2008, Janus Flexible Bond Fund returned 4.75%, compared to a 4.08% return for the Fund’s benchmark, the Lehman Brothers Aggregate Bond Index.

Economic Update

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. During this period of growing uncertainty, investors were attracted to U.S. Treasuries versus spread assets, helping to push interest rates lower across the yield curve. The escalation of the credit crisis and the Federal Reserve’s (Fed) aggressive interest rate reduction campaign, including an unprecedented inter-meeting cut of 75 basis points in January, helped to accelerate the downward move on interest rates for much of the period. The yield curve finished the six-month period ended April 30, 2008, with a much steeper slope as the yield on the 3-month Treasury bill fell by 253 basis points (2.53%) to 1.38% and the 10-year Treasury yield declined 74 basis points to 3.73%.

Additional subprime and mortgage related write-offs, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Interest rates reached their lows for the period and credit spreads moved to their widest levels in mid-March amid fears that credit conditions could suffer additional setbacks given a deteriorating liquidity position at investment bank Bear Stearns. Prior to that, periodic liquidity injections by the Fed failed to alleviate the stress in the credit markets. Financial markets stabilized after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept along with allowing broker/dealers to post collateral and borrow directly from the Fed and played an instrumental role in facilitating the saving of Bear Stearns by investment bank JP Morgan Chase. Without these moves the impact on the financial system and the overall economy would likely have been severe. By the end, the Fed had lowered its target interest rate from 4.50% to 2.00% during the period.

The decline in interest rates resulted in U.S. Treasuries outperforming other segments of the fixed-income markets during the period, but these moves were not without volatility. Inflation expectations rose given near-record commodity prices and the more accommodative stance taken by the Fed. But more moderate inflation readings late in the period tempered some of the anxiety. Meanwhile, spreads between mortgage-backed securities and high-yield and investment grade corporate debt to U.S. Treasuries increased to their widest levels on record, before declining a bit toward the end of the period. High-yield bonds posted modest declines in light of the significant widening in spreads during the period along side investment grade. The financials sector, which includes banks and broker/dealers, was among the weakest performing sectors for the period. The moves by the Fed stabilized the market, reducing liquidity premiums, helping spreads narrow late in the period and finish off well inside their widest levels reached before the bail out of Bear Stearns.

The uptrend in interest rates to close out the period can be attributed in part to investors beginning to look ahead to a possible economic recovery but more importantly to the rise of oil prices passing $110 per barrel during the period. Concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs in the financial sector, continued to weigh on the bond market.

U.S. Treasury and Bond Selection in the Credit Sector Aided Performance

Against the backdrop of uncertainty and risk aversion, the U.S. Treasury overweight position versus the benchmark provided the strongest contribution. We believe our bias toward holding a large position in U.S. Treasuries and other high-quality securities protected shareholders from much of the spread widening that occurred in the credit and mortgage areas of the market. This defensive position, in the interest of preservation of capital, proved timely.

Within our credit allocation, individual credits boosted performance. Among the top contributing credits over the period were Kinder Morgan Finance and Energy Future

(unaudited)

Holdings formerly TXU Energy before it was taken private. We have a high level of conviction in Kinder Morgan’s management team, their business model and the stable cash flows generated from their business and believe they are committed to paying down debt and achieving solid investment grade ratings. Energy Future Holdings was a solid performer as this Texas-based utility company benefited from what we believe is its competitive position, its ability to generate strong free cash flows and reduce overall leverage.

Mortgage-Backed Securities Detracted from Returns

Our relative underweight position in mortgage-backed securities benefited us as spreads were widening and MBS spreads reached levels never seen before as concerns around the housing markets and the stability of Fannie Mae and Freddie Mac raised concerns in the sector. This underweight proved detrimental toward the end of the period, as the Fed engineered market stability. While volatility persisted among mortgage-backed securities, their total returns benefited from the generally higher yields compared to U.S. Treasuries. Given the recent, Fed-engineered, stability in the markets, we will continue to look for opportunities to reduce our underweight, but remain committed to emphasizing the highest quality segments of the market.

During the period, the top individual detractors were floating rate notes and bank loans such as those issued by National Semiconductor and Univision Communications. National Semiconductor’s floating rate notes suffered relative to other issues within the company’s capital structure as the company pre-announced an earnings miss in February. Though the company eventually met estimates with its March report, the floating rate notes continued to underperform in other parts of the capital structure as the floating rate portion of the market has been under significant stress during the credit crunch. Bank loans from Univision Communications suffered as the market shied away from newly-issued, highly-levered debt used to finance many buy outs prior to the summer’s credit malaise. These holdings were also significantly hurt by the very quick and large declines in short-term interest rates directed by the Fed. As the London Interbank Offered Rate (LIBOR) reset lower, these securities re-priced to reflect the new short-term interest rates.

Outlook

Looking ahead, we will be paying close attention to the employment picture, the availability of credit and consumer confidence, among other things. Should the labor market continue to soften amid continued weakness in the housing market and the turmoil within the financial system, declining credit creation and further slowing in consumer spending is likely. While the government stimulus checks could provide a temporary boost, the current de-leveraging of the U.S. consumer could take time to complete, possibly lessening the potential for a sharp rebound in economic activity. Inflation remains a concern for the markets as well, given record commodity prices and the Consumer Price Index’s recent elevated level. Although inflation is generally a lagging indicator and should ease with slowing economic growth, it deserves attention given its negative impact and the notion that inflation may limit the Fed’s options to further stimulate economic growth.

The housing market could be the real problem for the U.S. economy and future consumption, given its ties to interest rates and credit markets. If the end-of-period uptrend in long-term interest rates continues and the spreads between mortgage-backed securities fail to narrow, or even widen, further weakness in housing could result. Away from the housing market, many investment-grade corporate balance sheets remained in relatively great shape with large cash balances and low leverage metrics. Because the new facilities introduced by the Fed and the current administration make almost the entire investment-grade market eligible as collateral and thus inexpensively financed, liquidity and trading within fixed-income markets should improve. In terms of the high-yield market, more care must be taken, as certain areas and names could do very well while other areas, namely highly levered companies, could struggle amid the system-wide de-leveraging – the health of the economy being very important for the high-yield market. Lastly, while corporate default rates are likely to rise over the next year, we could see a significant increase in merger & acquisition activity with many of the small high-yield issuers being bought by cash rich organizations taking advantage of their strong balance sheets and high-equity valuations. This could have important implications for business capital expenditures and thus economic activity. While this may be some months away, we will closely monitor these situations and their potential effect on our overall portfolio positioning and individual holdings.

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.

Janus Capital has contractually agreed to waive the Fund’s total operating expenses (excluding brokerage commissions, interest, dividends, taxes, and extraordinary expenses including, but not limited to, acquired fund fees and expenses) to a certain limit until at least March 1, 2009. The expense waiver is detailed in the Statement of Additional Information. Returns and yields shown include fee waivers, if any, and without such waivers, the Fund’s yield and returns would have been lower.

The fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2008. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.) Contractual waivers agreed to by Janus Capital, where applicable, are included in the prospectus 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.

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

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 managers.

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.

Returns include 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.

Janus High-Yield Fund (unaudited) Ticker: JAHYX

Fund Snapshot

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

Performance Overview

For the six-month period ended April 30, 2008, Janus High-Yield Fund returned (1.65)%, compared to a (0.74)% return of its benchmark, the Lehman Brothers High-Yield Bond Index.

Economic Update

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. During this period of growing uncertainty, investors were attracted to less risky U.S. Treasuries, at the expense of the high-yield market, helping to push interest rates lower across the yield curve. The Federal Reserve’s (Fed) aggressive interest rate reductions, including an unprecedented inter-meeting cut of 75 basis points drop in January, facilitated a significant decline in interest rates for much of the period. The yield curve finished the six-month period ended April 30, 2008, with a much steeper slope as the yield on the 3-month Treasury bill fell by 253 basis points (2.53%) to 1.38% and the 10-year Treasury yield declined 74 basis points to 3.73%.

Significant write-offs related to loose standards on mortgage, credit and subprime lending, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Interest rates reached their lows for the period and credit spreads moved to their widest levels in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns along with problems at other broker/dealers and regional banks. Prior to that, periodic liquidity injections by the Fed failed to alleviate the stress in the funding and credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept on repurchase agreements, allowed broker/dealers to post collateral and borrow directly from the Fed and ultimately facilitated the purchase of near-defunct Bear Stearns by JP Morgan Chase. Had the Fed not acted quickly and decisively on all of these fronts the impact on the financial system and the overall economy would likely have been very severe. By the end, the Fed had lowered its target interest rate from 4.50% to 2.00% during the period and provided significant liquidity to help ease the strains on the funding markets. These actions led to a significant decline in liquidity premiums and a return of some risk taking in the markets.

The decline in interest rates helped U.S. Treasuries outperform other segments of the bond market during the period, but these moves were not without volatility. Inflation expectations rose given near-record commodity prices and the more accommodative stance taken by the Fed. But more moderate inflation readings late in the period tempered some of the inflation anxieties in the market. Meanwhile, spreads between high-yield and investment-grade corporate debt to U.S. Treasuries widened, rising to levels not seen since the bursting of the NASDAQ bubble in 2001, before declining toward the end of the period. High-yield bonds posted modest declines, in light of the spread widening, during the period. Away from the pressure on the high-yield market, the financials sector was among the weakest performing within the credit markets. The moves by the Fed, resulting in increased market stability and declining liquidity premiums, helped spreads narrow late in the period and finish off their widest levels. Broker/dealers and banks staged a significant recovery in their spreads as the overall liquidity in the credit markets improved. This served as a positive for the high-yield market.

While spreads recovered, the uptrend in interest rates to close out the period can be attributed in part to investors beginning to look ahead to a possible economic recovery but more importantly the escalation of energy and commodity prices over the period leading to fears around rising inflation. As I write, oil has surpassed $110 a barrel and commodity prices hit new highs. Concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs, continued to weigh on the bond market.

Focus on More Liquid Credits Proved a Short-Term Negative

Early in the correction I saw significant pressure on the riskiest credits within the high-yield market. I was quick to reduce many of the riskier positions within the Fund, upgrading to higher quality more liquid names. My view was that rising liquidity premiums, due to the fundamental deterioration of the bank and brokerage sector, would put significant pressure on the high-yield market. Our expectation of spread widening

played out through the purchase of Bear Stearns. I focused on holding companies with strong fundamentals and high-liquidity positions. These securities, while fundamentally safe, tend to suffer the brunt of the initial sell-off as market participants look to unload their most marketable bonds first. I saw the effects of this early in the correction. Nonetheless, I believe these more stable, fundamentally better issues should perform well on a relative basis as long as uncertainty remains in the credit markets. As the correction accelerated, I saw the more illiquid and lower-rated names push to the downside, with many individual credits trading down 10-15 points. I avoided many of the names that saw the largest price declines (less liquid, lower quality). Post the bail out of Bear Stearns, risk taking returned to the market and liquidity premiums collapsed as the perception that the Fed would remedy any new problems presented in the market. This led to a snap back in these credits and overall improvement in the market. While remaining in a defensive position, I did not capture the upside generated by the higher-risk, lower-quality positions in the market.

The largest detractor from performance for the period was a bank loan issued by Travelport Holdings. As a travel company providing reservation services to consumers and businesses, rising oil prices and concerns about a slowing economy put downward pressure on expectations for the company’s results. I held Travelport based on my view that a near-term liquidity event would give the company the opportunity to pay down existing debt. Given the credit market conditions at the end of the period, such an event is likely pushed further into the future. Negative expectations around the liquidity event as well as the bank loan’s lower position in the capital structure also pressured the security.

Another detractor was R.H. Donnelley. Concerns about the macro-environment pressured expectations for R.H. Donnelley as a significant portion of its revenues come from small business advertising. Historically the yellow page businesses have proven to be very recession resistant, providing stable cash flows. The company surprised the market with an earnings pre-announcement that drove the shares lower and brought into question the long-term sustainability of the business model. Given the surprise and the more cyclical correlation to the economy, I sold our position to zero early in the correction. As the market rebounded I received more clarity around the operating conditions of the company and their liquidity position, so if conditions continue to improve I plan to repurchase a position in the name. I am watching the fundamentals and the liquidity position of the company closely and believe that the bonds could offer good upside potential versus downside risk in the Fund.

Select Energy and Non-Cyclical Food and Beverage Bonds Aided Performance

Energy Future Holdings, formerly TXU Energy, was the top contributing security in the Fund during the period. I bought the bonds after the leveraged buyout (LBO) as I saw a significant de-leveraging opportunity for this deregulated power producer. Post LBO, the company began heading in the right direction and could benefit from rising energy prices in Texas. In addition, the company’s competitive position in the state of Texas remained well protected at period end.

Another top contributor for the period was Aramark, a commercial services company that exhibited strong free cash flow and has historically been a recession-resistant business. The risk/reward profile for our Aramark position remained compelling and I believe over the longer term this high-quality business model and non-cyclical business should be able to generate free cash flow throughout the economic cycle. Aramark is led by a management that understands value creation in moving a company from public to private and then back to public, I feel this is a rare opportunity to be aligned with a management team as a bond holder of the company.

Outlook

Looking ahead, I will be paying close attention to the employment picture, the state of the financial sector, the availability of credit and consumer confidence, among other things. Should the labor market continue to soften amid contracting credit conditions and continued weakness in the housing market, further slowing in consumer spending is likely. While the government stimulus checks could provide a temporary boost, the current de-leveraging of the U.S. consumer could take time to complete, possibly lessening the potential for a sharp rebound in economic activity. Inflation remains a concern for the markets as well, given record commodity prices and the Consumer Price Index’s recent elevated level. Although inflation is generally a lagging indicator and should ease with slowing economic growth, it deserves attention given its negative impact and the notion that inflation may limit the Fed’s options to further stimulate economic growth. I recognize that housing plays an important role in the current calculation of the inflation figures but have tended to pay more close attention to the inflation pressures on staple goods and their effects of discretionary consumption patterns of the U.S. consumer.

In light of this, the housing market could be the core problem for the U.S. economy going forward, given its ties to interest rates and credit markets. If the end-of-period uptrend in long-term interest rates continues and the spreads between mortgage-backed securities fail to narrow, or even widen, further weakness in housing could result. This environment would likely result in additional write-downs within the financial sector, further delaying the recovery process. This could also spell additional risk for the high-yield market as liquidity premiums would likely reverse course leading to wider spreads. Away from the significant deterioration in the fundamentals of the financial sector, many investment-grade corporate balance sheets remained in great shape with large cash balances. Because the new facilities introduced by the Fed and the current administration make almost the entire investment-grade market eligible as collateral and thus inexpensively financed, liquidity and trading within fixed income markets could improve. In terms of the high-yield market, more care must be taken, as certain areas and names could do very well while other areas, namely highly levered companies, could struggle amid the system-wide deleveraging. Lastly, while corporate default rates are likely to rise over the next year, we could see a significant increase in merger and acquisition activity with many of the small high-yield issuers being bought by cash rich, larger organizations taking advantage of their strong balance sheets and high-equity valuations. This could have important implications for business capital expenditures and thus economic activity. While this may be some months away, I will closely monitor these situations and their potential effect on our individual holdings.

Within the Fund, I will continue to seek to uncover opportunities through fundamental bottom-up research that I believe present an attractive risk/reward profile. I’m supported by a fantastic team of analysts, traders and risk professionals that are focused on delivering for our clients. While these have been very volatile times, filled with periods of significant uncertainty, preservation of capital remains a primary focus followed by exploiting the opportunities presented by the ever-changing market. Many of our best investment ideas currently generate free cash flow and are supported by asset-heavy balance sheets and historically recession-resistant businesses. In addition, I am focusing on management teams that have managed through difficult times and understand the importance of balance within their capital structures. All in all, strong businesses with excellent management tend to thrive in volatile times.

Thank you for entrusting your assets to us and for your investment in Janus High-Yield Fund.

Janus Capital has contractually agreed to waive the Fund’s total operating expenses (excluding brokerage commissions, interest, dividends, taxes, and extraordinary expenses including, but not limited to, acquired fund fees and expenses) to a certain limit until at least March 1, 2009. The expense waiver shown reflects the application of such limit and is detailed in the Statement of Additional Information. Returns and yields shown include fee waivers, if any, and without such waivers, the Fund’s yield and returns would have been lower.

A 2% redemption fee may be imposed on shares held for 90 days or less. Performance shown does not reflect this redemption fee and, if reflected, performance would have been lower.

The fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2008. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.) Contractual waivers agreed to by Janus Capital, where applicable, are included in the prospectus 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.

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

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.

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.

The Fund invests in Real Estate Investment Trusts (REITs) which may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: liquidity, decline in the value of real estate, risks related to general and economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Fund invests in foreign REITs, the Fund may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

Returns include 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.

Performance Overview

For the six-month period ended April 30, 2008, Janus Short-Term Bond Fund posted a gain of 2.39%, compared to a 3.88% increase of its benchmark, the Lehman Brothers Government/Credit 1-3 Year Index.

Economic Update

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. During this period of growing uncertainty, investors were attracted to less risky U.S. Treasuries, helping to push interest rates lower across the yield curve. The Federal Reserve’s aggressive interest rate reduction, including an unprecedented inter-meeting cut of 75 basis points (bps) in January, helped to keep the downward pressure on interest rates for much of the period. The yield curve finished the six month period ended April 30, 2008, with a much steeper slope as the yield on the 3-month Treasury bill fell by 253 bps to 1.38% and the 10-year Treasury yield declined 74 bps to 3.73%.

Additional subprime-related write-offs, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Interest rates reached their lows for the period and credit spreads moved to their widest levels in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept and played an instrumental role in JP Morgan Chase’s purchase of Bear Stearns. In the end, the Fed lowered its target interest rate from 4.50% to 2.00% during the period.

The decline in interest rates helped U.S. Treasuries outperform other segments of the bond market during the period, but these moves were not without volatility. Inflation expectations rose given near-record commodity prices and the more accommodative stance taken by the Fed. But more moderate inflation readings late in the period tempered some of the anxiety. Meanwhile, mortgage-backed security, high-yield and investment grade spreads to U.S. Treasuries widened, or rose to their highest levels, before declining a bit toward the end of the period.

The uptrend in interest rates to close out the period can be attributed in part to investors beginning to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs, continued to weigh on the bond market.

Credit and Agency/Government Sponsored Debt Exposure Hindered Performance

The Fund’s underperformance during the period was largely driven by our allocation to high yield and leveraged loans. Below investment grade credit significantly underperformed higher grade credit, as most investors moved up in credit quality.

An underweight to agency/government sponsored debt also detracted from performance during the period. While we will look to add to our agency position, bringing it closer to the benchmark weight, we continue to believe that among the highest quality debt, U.S. Treasuries offer the best defense against market uncertainty.

Our credit position in Denny’s, a restaurant chain, also fell on concerns about a consumer-led economic slowdown hurting their business, however, operations at the company remained strong and same-store sales increased. Within Denny’s capital structure, they have been selling off stores to franchisees and using the proceeds to pay down debt.

Treasury Holdings Benefited Results

Against the backdrop of uncertainty and risk aversion, the U.S. Treasury overweight position versus the benchmark made the strongest contribution. We believe our bias toward the highest-quality securities protected shareholders from much of the spread widening that occurred in the credit and mortgage areas of the market.

Among individual credits, bonds issued by Berkshire Hathaway were the top contributor to performance in the

six-month period. During the tumultuous market conditions, investors gravitated toward blue chip names finding comfort in what we believe to be exceptional management teams with a long-standing history of market leadership.

Outlook

Looking ahead, we will be paying close attention to the employment picture, the availability of credit and consumer confidence, among other things. Should the labor market continue to soften amid continued weakness in the housing market, further slowing in consumer spending is likely. While the government stimulus checks could provide a temporary boost, the current de-leveraging of the U.S. economy could take time to complete, possibly lessening the potential for a sharp rebound in economic activity. Inflation remains a concern for the markets as well, given record commodity prices and the Consumer Price Index’s recent elevated level. Although inflation is generally a lagging indicator and should ease with slowing economic growth, it deserves attention given its negative impact and the notion that inflation may limit the Fed’s options to further stimulate economic growth.

The housing market could be the real problem for consumers, given its ties to interest rates and credit markets. If the end-of-period uptrend in long-term interest rates continues and borrowing costs widen, further weakness in housing could result. Nevertheless, investment-grade corporate balance sheets remained in great shape with large cash balances. Because the new facilities introduced by the Fed and the Bush administration make almost the entire investment-grade market eligible as collateral and thus inexpensively financed, liquidity and trading within fixed income markets could improve. Lastly, while corporate default rates are likely to rise over the next year, we could see a significant increase in merger and acquisition activity with many of the small high-yield issuers being bought by cash rich organizations taking advantage of their strong balance sheets and high equity valuations. This could have important implications for business capital expenditures and thus economic activity. While this may be some months away, we will closely monitor these situations and their potential effect on our individual holdings.

Thank you for your investment in Janus Short-Term Bond Fund.

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.

Janus Capital has contractually agreed to waive the Fund’s total operating expenses (excluding brokerage commissions, interest, dividends, taxes, and extraordinary expenses including, but not limited to, acquired fund fees and expenses) to a certain limit until at least March 1, 2009. The expense waiver is detailed in the Statement of Additional Information. Returns and yields shown include fee waivers, if any, and without such waivers, the Fund’s yield and returns would have been lower.

The fees and expenses shown were determined based on net assets as of the fiscal year ended October 31, 2008. The expense information shown may include “acquired fund” fees and expenses. (“Acquired Fund” means any underlying fund (including, but not limited to, exchange-traded funds) in which a Fund invests or has invested during the period.) Contractual waivers agreed to by Janus Capital, where applicable, are included in the prospectus 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.

Janus Short-Term Bond Fund (unaudited)

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 managers.

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.

The Fund invests in Real Estate Investment Trusts (REITs) which may be subject to a higher degree of market risk because of concentration in a specific industry, sector or geographic region. REITs may be subject to risks including, but not limited to: liquidity, decline in the value of real estate, risks related to general and economic conditions, changes in the value of the underlying property owned by the trust and defaults by borrowers. To the extent the Fund invests in foreign REITs, the Fund may be subject to fluctuations in currency rates or political or economic conditions in a particular country.

Returns include 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.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

September 3, 1992 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.

See Notes to Schedules of Investments for index definitions.

The Fund’s portfolio may differ significantly from the securities held in the index. The index is unmanaged and is not available for direct investment; therefore its performance does not reflect the expenses associated with the active management of an actual portfolio.

Data presented represents past performance, which is no guarantee of future results. 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.

Investments in money market funds are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the money market funds seek to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the money market 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, 2007. 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.

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 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 is 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 twenty-nine funds. The Bond Funds invest primarily in income-producing securities, and the Money Market Funds invest in high-quality money market instruments. Each Bond Fund 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.

On December 14, 2007, the Board of Trustees of the Trust approved a plan to liquidate and terminate Janus Federal Tax-Exempt Fund. Effective February 26, 2008, Janus Federal Tax-Exempt Fund was liquidated from the Trust.

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. Investments held by the Money Market Funds are valued utilizing 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. Circumstances in which fair value pricing may be utilized include, but are not limited to: (i) when significant events occur which may affect the securities of a single issuer, such as mergers, bankruptcies, or significant issuer-specific developments; (ii) when significant events occur which may affect an entire market, such as natural disasters or significant governmental actions; and (iii) when non-significant events occur such as markets closing early or not opening, security trading halts, or pricing of non-valued securities and restricted or non-public securities. 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. Dividends from foreign securities may be subject to withholding taxes in foreign 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.

54  Janus Bond and Money Market Funds  April 30, 2008

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. 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 if time permits. 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, time deposits, repurchase agreements, money market mutual funds or other money market accounts, 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.

Dresdner Bank AG (the “Lending Agent”) may also invest the cash collateral in the Allianz Dresdner Daily Asset Fund 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.

As of April 30, 2008, the Funds had on loan securities valued as indicated:

	Value at
Fund	April 30, 2008
Bond
Janus Flexible Bond Fund	$	213,754,560
Janus High-Yield Fund		29,097,099
Janus Short-Term Bond Fund		48,772,783

As of April 30, 2008, the Funds received cash collateral for securities lending activity as indicated:

	Cash Collateral at
Fund	April 30, 2008
Bond
Janus Flexible Bond Fund	$	218,546,114
Janus High-Yield Fund		29,794,885
Janus Short-Term Bond Fund		49,943,382

As of April 30, 2008, all cash collateral received by the Funds was invested in the Allianz Dresdner Daily Asset Fund, except as noted in the following tables:

Fund	Time Deposits
Bond
Janus Flexible Bond Fund	$	99,878,207
Janus High-Yield Fund		11,938,943
Janus Short-Term Bond Fund		23,966,162

Fund	Repurchase Agreements
Bond
Janus Flexible Bond Fund	$	34,550,137
Janus High-Yield Fund		3,906,746
Janus Short-Term Bond Fund		7,842,381

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 loaned 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 the Lending Agent. The Lending Agent may retain a portion of the interest earned on the cash collateral invested. The cash collateral invested by the Lending Agent is disclosed in the Schedule of Investments (if applicable). The lending fees and the Funds’ portion of the interest income earned on cash collateral are included on the Statement of Operations (if applicable).

Interfund Lending

Pursuant to an exemptive order received from the SEC, the Funds may be party to interfund lending agreements between the Funds and other Janus Capital-sponsored mutual funds, which permit 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 the borrowing Funds’ 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 Bond Funds may enter into forward currency contracts in order to reduce exposure to changes in foreign currency exchange rates on 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

Janus Bond and Money Market Funds  April 30, 2008  55

Notes to Financial Statements (unaudited) (continued)

investment and 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.

Futures Contracts

The Bond Funds may enter into futures contracts to gain exposure to the stock market pending investment of cash balances or to meet liquidity needs. The Funds may also 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 values 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 as “Net realized gain/(loss) from futures contracts” 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 Funds’ custodian.

Swaps

The Bond Funds may enter into swap agreements to hedge their exposure to interest rates and credit risk or for investment purposes. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. Swap contracts are reported as an asset and liability on the Statement of Assets and Liabilities. Realized gains and losses are reported in “Net realized gain/(loss) from swap contracts” on the Statement of Operations (if applicable).

Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the swap contract. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Funds, and/or the termination value. Therefore, the Funds consider the creditworthiness of each counterparty to a swap contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities.

Options Contracts

The Bond Funds may purchase or write put and call options on futures contracts and portfolio securities for hedging purposes or as a substitute for an investment. The Bond Funds may also purchase or write put and call options on foreign currencies in a manner similar to that in which futures or forward contracts on foreign currencies will be utilized. The Funds may also invest in Long-Term Equity Anticipation Securities (LEAPS), which are long-term option contracts that can be maintained for a period up to three years. The Bond Funds generally invest in options to hedge against adverse movements in the value of portfolio holdings.

When an option is written, the 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 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 Funds could result in the Funds 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 are 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).

The Funds may also purchase and write exchange-listed and over-the-counter put and call options on domestic securities indices, and on foreign securities indices listed on domestic and foreign securities exchanges. Options on securities indices are similar to options on securities except that (1) the expiration cycles of securities index options are monthly, while those of securities options are currently quarterly, and (2) the delivery requirements are different. Instead of giving the right to take or make delivery of securities at a specified price, an option on a securities index gives the holder the right to receive a cash “exercise settlement amount” equal to (a) the amount, if any, by which the fixed exercise price of the option exceeds (in the case of a put) or is less than (in the case of a call) the closing value of the underlying index on the date of exercise, multiplied by (b) a fixed “index multiplier.” Receipt of this cash amount will depend upon the closing level of the securities index upon which the option is based being greater than, in the case of a call, or less than, in the case of a put, the exercise price of the index and the exercise price of the option times a specified multiple. The writer of the option is obligated, in return for the premium received, to make delivery of this amount.

56  Janus Bond and Money Market Funds  April 30, 2008

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 as “Options written at value” (if applicable).

Realized gains and losses are reported as “Net realized gain/(loss) from options contracts” on the Statement of Operations (if applicable).

The risk in writing call options is that the Funds give up the opportunity for profit if the market price of the security increases and the option is exercised. The risk in writing put options is that the Funds may incur a loss if the market price of the security decreases and the option is exercised. The risk in buying options is that the 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 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 Funds’ 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 the Funds may recognize due to written call options.

Mortgage Dollar Rolls

The Bond Funds may enter into “mortgage dollar rolls.” In a “mortgage dollar roll” transaction, the Funds sell a mortgage-related security (such as a Government National Mortgage Association (“Ginnie Mae”) security) to a dealer and simultaneously agree to repurchase a similar security (but not the same security) in the future at a pre-determined price. The Funds 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 Funds’ 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 Funds, maintained in a segregated account. To the extent that the Funds collateralize their 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 portfolio managers’ ability to predict interest rates and mortgage payments. Dollar roll transactions involve the risk that the market value of the securities the Funds are required to purchase may decline below the agreed upon repurchase price.

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 Funds commit 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 Ginnie Mae, Federal National Mortgage Association (“Fannie Mae”) and/or Federal Home Loan Mortgage Corporation (“Freddie Mac”) transactions.

Securities purchased on a TBA basis are not settled until they are delivered to the Funds, normally 15 to 45 days later. Beginning on the date the Funds enter 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.

Floating Rate Loans

The Bond Funds may invest in floating rate loans. Floating rate loans are debt securities that have floating interest rates which adjust periodically are tied to a benchmark lending rate such as the London Interbank Offered Rate (“LIBOR”). LIBOR is a short-term interest rate that banks charge one another and that is generally representative of the most competitive and current cash rates. In other cases, the lending rate could be tied to the prime rate offered by one or more major U.S. banks (“Prime Rate”) or the rate paid on large certificates of deposit traded in the secondary markets (“CD Rate”). If the benchmark lending rate changes, the rate payable to lenders under the loan will change at the next scheduled adjustment date specified in the loan agreement. Floating rate loans are typically issued to companies (“borrowers”) in connection with recapitalizations, acquisitions, and refinancings. Floating rate loan investments are generally below investment grade. Senior floating rate loans are secured by specific collateral of a borrower and are senior in the borrower’s capital structure. The senior position in the borrower’s capital structure generally gives holders of senior loans a claim on certain of the borrower’s assets that is senior to subordinated debt and preferred and common stock in the case of a borrower’s default. Floating rate loan investments may involve foreign borrowers, and investments may be denominated in foreign currencies. Floating rate loans often involve borrowers whose financial condition is troubled or uncertain and companies that are highly leveraged. The Funds may invest in obligations of borrowers who are in bankruptcy proceedings. Floating rate loans may include fully funded term loans or revolving lines of credit.

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

Janus Bond and Money Market Funds  April 30, 2008  57

Notes to Financial Statements (unaudited) (continued)

the loan, as specified in the loan agreement. When investing in a loan participation, the Funds have the right to receive payments of principal, interest and any fees to which they are entitled only from the Lender selling the loan agreement and only upon receipt by the Lender of payments from the borrower. The Funds generally have 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 Funds invest generally are readjusted periodically to an increment over a designated benchmark rate, such as the one-month, three-month, six-month, or one-year LIBOR.

The Funds 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 Funds 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 Funds utilize an independent third party to value individual bank loans on a daily basis.

The average monthly value of borrowings outstanding under bank loan arrangements and the related rate range during the six-month period ended April 30, 2008, are indicated in the table below.

	Average Monthly
Fund	Value		Rates
Bond
Janus Flexible Bond Fund	$	11,312,284		0.2948%-8.70%
Janus High-Yield Fund		22,452,888		0.15%-12.198%
Janus Short-Term Bond Fund		7,777,319		1.85%-9.00%

Short Sales

The Funds may engage in “short sales against the box.” Short sales against the box involve either selling short a security that the Funds own, or selling short a security that the Funds have the right to obtain, for delivery at a specified date in the future. The Funds may enter into a short sale against the box to hedge against anticipated declines in the market price of portfolio securities. The Funds do not deliver from their portfolios the securities sold short and do not immediately receive the proceeds of the short sale. The Funds borrow the securities sold short and receive proceeds from the short sale only when they deliver the securities to the lender. If the value of the securities sold short increases prior to the scheduled delivery date, the Funds lose the opportunity to participate in the gain.

Foreign Currency Translations

The Funds do not isolate that portion of the results of operations resulting from the effect of 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. Unrealized net appreciation or depreciation of investments and foreign currency translations arises 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 foreign 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.

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 Funds may hold liquid assets as collateral with the Funds’ custodian sufficient to cover the purchase price.

Exchange-Traded Funds

The Bond Funds may invest in exchange-traded funds, which are index-based investment companies which hold substantially all of their assets in securities representing their specific index. As a shareholder of another investment company, a Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operations.

Equity-Linked Structured Notes

The Bond 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 non-registered 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

58  Janus Bond and Money Market Funds  April 30, 2008

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

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. The Funds may not experience similar performance as their assets grow.

Additional Investment Risk

The Bond Funds 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

Restricted securities held by the Funds may not be sold except in exempt transactions or in a public offering registered under the Securities Act of 1933, as amended. 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 the Funds 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 of net investment income are declared daily and generally distributed monthly. Realized capital gains, if any, are declared and distributed in December. The majority of dividends and capital gains distributions from the Funds will be automatically reinvested into additional shares of that Fund, based on the discretion of the shareholder.

The Bond Funds may make certain investments in real estate investment trusts (“REITs”) which pay dividends to their shareholders based upon funds available from operations. It is quite common for these dividends to exceed the REIT’s taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital. If the Funds distribute such amounts, such distribution could constitute a return of capital to shareholders for federal income tax purposes.

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.

The Funds adopted the provisions of Financial Accounting Standards Board (“FASB”) Interpretation No. 48 (“FIN 48”). Accounting for Uncertainty in Income Taxes on April 30, 2008. FIN 48 requires an evaluation of tax positions taken (or expected to be taken) in the course of preparing a Fund’s tax return to determine whether these positions meet a “more-likely-than-not” standard that based on the technical merits have a more than fifty percent likelihood of being sustained by a taxing authority upon examination. A tax position that meets the “more-likely-than-not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations.

FIN 48 requires management of the Funds to analyze all open tax years, fiscal years 2003-2006 as defined by Statute of Limitations, for all major jurisdictions, including federal tax authorities and certain state tax authorities. As of and during the six-month period ended April 30, 2008, the Funds did not have a liability for any unrecognized tax benefits. The Funds have no examination in progress and are not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

New Accounting Pronouncements

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS No. 157”), which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS No. 157 does not require new fair value measurements, but is applied to the extent that other accounting pronouncements require or permit fair value measurements. SFAS No. 157 emphasizes that fair value is a market-based measurement that should be determined based

Janus Bond and Money Market Funds  April 30, 2008  59

Notes to Financial Statements (unaudited) (continued)

on the assumptions that market participants would use in pricing an asset or liability. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. Management does not believe the adoption of SFAS No. 157 will impact the financial statement amounts; however, the Funds will be required to disclose the extent to which fair value is used to measure assets and liabilities and the inputs used to develop the measurements.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS No. 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. SFAS No. 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. SFAS No. 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. Management does not believe the adoption of SFAS No. 159 will impact the financial statement amounts.

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS No. 161”), which requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. SFAS No. 161 is effective for financial statements issued for fiscal years beginning after November 15, 2008, and interim periods within those fiscal years. Management is in the process of evaluating the impact of SFAS No. 161 on the Funds’ financial statement disclosures.

2.  Investment Advisory Agreements and Other Transactions with Affiliates

The Funds pay a monthly advisory fee to Janus Capital based upon average daily net assets and calculated at the annual rate shown in the table below:

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

Until at least March 1, 2009, 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 the Fund’s normal operating expenses in any fiscal year, including the investment advisory fee, but excluding brokerage commissions, interest, dividends, taxes and extraordinary expenses (including, but not limited to, acquired fund fees and 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 %
Bond
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 pay Janus Capital an administrative services fee of 0.50% 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.

Each Fund pays Janus Services LLC (“Janus Services”), a wholly-owned subsidiary of Janus Capital and the Funds’ transfer agent, 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 for transfer agent services.

During the fiscal year ended October 31, 2007, Janus Services reimbursed the following Fund 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, 2008, Janus Capital assumed $16,904 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 the Pending Legal Matters. 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 the Portfolios that commenced operations after July 31, 2004. Additionally, all future non-recurring costs will be allocated to the Portfolios based on 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 Board of Trustees has adopted a deferred compensation plan (the “Deferred 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 are credited to the account. The fluctuation of the account balance is recorded by the Funds as unrealized appreciation/(depreciation) and is shown as of April 30, 2008 on the Statement of Assets and Liabilities as an asset, “Non-interested Trustees’ deferred compensation,” and a liability, “Non-interested Trustees’ deferred compensation fees.” Additionally, the recorded unrealized appreciation/(depreciation) is included in “Unrealized net appreciation/(depreciation) of investments, foreign currency translations and non-interested Trustees’ deferred compensation” for the Bond Funds, and “Unrealized net appreciation/(depreciation) of investments and non-interested Trustees’ deferred compensation” for the Money Market Funds on the Statement of Assets and Liabilities. Deferred compensation expenses for the six-month period ended April 30, 2008 are included in “Non-interested Trustees’ fees and expenses” on the Statement of Operations. Trustees are allowed to change their designation of mutual funds from time to time. Amounts will be deferred until distributed in accordance with the Deferred Plan. No deferred fees were paid to any Trustee under the Deferred Plan during the six-month period ended April 30, 2008.

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 Trust. Total compensation of $39,907 was paid by the Trust during the six-month period ended April 30, 2008. Each Fund’s portion is reported as part of “Other Expenses” on the Statement of Operations.

A 2.00% redemption fee may be imposed on shares of Janus High-Yield Fund 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 the Fund for the six-month period ended April 30, 2008 are indicated in the table below:

Fund	Redemption Fee
Janus High-Yield Fund	$	58,478

The Bond Funds’ expenses may be reduced by expense offsets from an unaffiliated custodian and/or transfer agent. Such credits or offsets are included in “Expense and Fee Offset” 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.

The Bond Funds may invest in money market funds, including funds managed by Janus Capital. During the six-month period ended April 30, 2008, the following Funds recorded distributions from affiliated investment companies as affiliated dividend income, and had the following affiliated purchases and sales:

4.  Federal Income Tax

Income and capital gains distributions are determined in accordance with income tax regulations that may differ from accounting principles generally accepted in the United States of America. These differences are due to differing treatments for items such as net short-term gains, deferral of wash sale losses, foreign currency transactions, net investment losses and capital loss carryovers.

The Funds have elected to treat gains and losses on forward foreign currency contracts as capital gains and losses. Other foreign currency gains and losses on debt instruments are treated as ordinary income for federal income tax purposes pursuant to Section 988 of the Internal Revenue Code.

The aggregate cost of investments and the composition of unrealized appreciation and depreciation of investment securities for federal income tax purposes as of April 30, 2008 are noted below.

Unrealized appreciation and unrealized depreciation in the table below exclude appreciation/depreciation on foreign currency translations. The primary difference between book and tax appreciation or depreciation of investments is wash sale loss deferrals.

6.  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 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

64  Janus Bond and Money Market Funds  April 30, 2008

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. The appeal is still pending and argument in the matter was held in December 2007. 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. However, in June 2007, Plaintiffs appealed that dismissal to the United States Court of Appeals for the Fourth Circuit. That appeal is currently pending.

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 status conference was held on June 28, 2007, during which the parties were ordered to submit their proposed scheduling order. To date, no scheduling order has been entered in the case. In addition to the pending Motion to Discharge Order to Show Cause, 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.

During 2007, two lawsuits were filed against Janus Management Holdings Corporation (“Janus Holdings”), an affiliate of JCGI, by former Janus portfolio managers, alleging that Janus Holdings unilaterally implemented certain changes to compensation in violation of prior agreements. These complaints allege some or all of the following claims: (1) breach of contract; (2) willful and wanton breach of contract; (3) breach of good faith and fair dealing; and (4) estoppel. Janus Holdings filed Answers to these complaints denying any liability for these claims and intends to vigorously defend against the allegations.

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, none of whom has ever been affiliated with Janus Capital (“Independent Trustees”), oversee the management of each Fund 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 Fund, 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 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 with management to consider the agreements, and also met separately in executive session with their independent legal counsel and their independent fee consultant.

At a meeting held on December 14, 2007, based on their evaluation of the information provided by Janus Capital, the subadvisers and the independent fee consultant, as well as other information, the Trustees determined that the overall arrangements between each Fund and Janus Capital and each subadviser, as applicable, 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 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, 2008 through February 1, 2009 (January 1, 2008 through January 1, 2009 for INTECH Risk-Managed Stock Fund and Janus Global Research Fund), subject to earlier termination as provided for 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, the knowledge of 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 and/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 those 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

66  Janus Bond and Money Market Funds  April 30, 2008

appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract well-qualified personnel.

Performance of the Funds

The Trustees considered the investment performance 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 many 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 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, 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.

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 fee rates for Funds having a similar strategy, the Trustees noted that, under the terms of 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, the Trustees 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.

The Trustees reviewed information on the profitability to Janus Capital and its affiliates of their relationships with each Fund, as well as an explanation of the methodology used in allocating various expenses of Janus Capital and its affiliates among the Funds and other clients. They 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 receives adequate incentives to manage the Funds effectively. They 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 adviser, 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 payable by Janus Capital or the Funds to the subadvisers of subadvised Funds, were reasonable in relation to the nature, extent 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 subadvisers charge to other clients. They 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, those Funds benefited from having advisory fee rates that remained constant rather than increasing as assets declined. In addition, performance fee structures have been

Janus Bond and Money Market Funds  April 30, 2008  67

Additional Information (unaudited) (continued)

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. They also considered Janus Capital’s past and proposed use of commissions paid by Funds on their portfolio brokerage transactions to obtain proprietary and third-party research products and services benefiting those Funds and/or other clients of Janus Capital. The Trustees concluded that Janus Capital’s use of “soft” commission dollars of a Fund to obtain proprietary and third-party 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 also concluded that Janus Capital benefits from the receipt of proprietary and third-party 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, all of whom are 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 (from inception) 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 dividends and distributions, 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 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, 2007. 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 written options contracts follows each Fund’s Schedule of Investments (if applicable). Written options 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 will 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 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 and expense reimbursements, if any, are also shown.

The last section lists the increase or decrease in the value of securities held in the Funds. The 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 Funds’ 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 will 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 withdrawals via redemptions. “Redemption Fees” (if applicable) refers to the fee paid to the Funds for shares held for 90 days 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 each Fund’s net asset value (“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 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 frequency of dividend payments 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 the offset and the net expenses. The

70  Janus Bond and Money Market Funds  April 30, 2008

expense ratios listed in the Financial Highlights reflect total expenses prior to any expense offset (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 size asset 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.

Janus provides access to a wide range of investment disciplines.

Asset Allocation

Janus asset allocation portfolios 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.

Co-Chief Investment Officers’ Letter to the Shareholders

Jonathan Coleman

Co-Chief Investment Officer

Gibson Smith

Co-Chief Investment Officer

Dear Shareholders,

Challenging economic conditions have been the dominant theme for the financial markets over the past several months. Despite recent volatility, our investment team has maintained a relentless focus on our fundamental, bottom-up research process and has continued to discover compelling investment opportunities for our shareholders.

Major Market Themes

Turmoil in the credit markets, uncertainty surrounding the near-term outlook for the U.S. economy and a weaker corporate profit picture made for a volatile and difficult market environment over the past several months. While sentiment toward the end of the period improved and U.S. equity markets finished well above their mid-March lows, stocks were broadly lower over the six months ended April 30, 2008. The Russell 1000^® Index declined 9.54%, the Russell 2000^® Index was down 12.92% and the Morgan Stanley Capital International (MSCI) All Country World Index^SM gave up 9.47% during the period. Fixed-income markets proved to be volatile over the period with the Lehman Brothers Aggregate Bond Index up 4.08% and the Lehman Brothers High-Yield Bond Index lost 0.74% over the period.

Additional write-offs related to the loose lending practices over the previous 36 months, slowing consumer spending and a softening labor market, accompanied by record commodity prices and rising inflation expectations, weighed on investor sentiment during the period. Stocks reached their lows in mid-March amid fears that credit conditions could suffer another setback given a deteriorating liquidity position at investment bank Bear Stearns. Uncertain market conditions resulted in interest rates hitting five-year lows with the 10-Year Treasury Note touching 3.33%. Prior to that, periodic liquidity injections by the Federal Reserve (Fed) failed to alleviate the stress in the funding and credit markets. Financial markets stabilized somewhat after the Fed aggressively lowered the Federal Funds rate, expanded the collateral it would accept, allowed for broker/dealers to borrow directly from the Fed and played an instrumental role in JPMorgan Chase’s purchase of near-defunct Bear Stearns. All of these moves were vitally important toward stabilizing the financial system while allowing for the recovery process to continue. By the end, the Fed had lowered its target interest rate from 4.50% to 2.00% during the period.

Following the March lows, the equity market’s rally at the end of the six-month period can be attributed to the moves by the Fed and, in part, to improving sentiment as investors began to look ahead to a possible economic recovery. Nevertheless, concerns about elevated inflationary pressures, soft consumer spending, the weak housing market and the lingering possibility of more write-downs continued to weigh on the market.

Performance Notables

For the one-year period ended April 30, 2008, 77% of Janus’ retail funds ranked within Lipper’s top two quartiles, based upon total returns. The results were even stronger over longer time periods as 87% of our retail funds achieved first- or second-quartile Lipper rankings over three years and 86% ranked in Lipper’s top two quartiles over five years. Furthermore, 78.3% of our retail funds had a 4- or 5-star overall Morningstar Rating^tm as of April 30, 2008, well ahead of the 32.5% of funds for which Morningstar awards 4- or 5-stars in each category. (See complete Lipper rankings on page 3 and complete Morningstar Ratings^tm on page 4).

Investment Team Update

We continue to enhance the breadth of our global stock coverage and work tirelessly to generate solid investment insights in an attempt to deliver superior investment performance. Our hands-on research approach is critical to our stock selection process. As such, the Janus equity research team traveled over 2.9 million miles in 2007 investigating potential stock and bond picks worldwide. This year, we plan to embark on a multi-year strategy to locate certain investment personnel closer to the companies that they research as an important first step in building out our global footprint from a research standpoint.

While our objective is to develop a research edge and invest with conviction in our funds, we seek to do so in a disciplined and thoughtful way by clearly understanding and managing risk in our portfolios. Dan Scherman, Director of Risk and Trading, works continually with our investment management

team to ensure that portfolio risks are intentional and calculated. We believe this analysis is both timely and critical as we navigate today’s challenging markets.

Conclusion

As we look back over the past six months, we are relieved that signs of stabilization appeared in the financial markets as the period came to a close. However, we recognize that there are still significant challenges ahead. Increasing risk aversion has resulted in a significant contraction of credit availability for both consumers and corporations. The tightening of credit, along with declining real estate prices, rising energy prices and a climbing unemployment rate may all create significant economic headwinds in the near future. While unsettling, we believe this is a natural and necessary process of recovery from the excessive risk-taking and loose lending standards that developed over the previous several years in many areas of the credit markets. We feel that the environment will improve as the healing process progresses.

So, as we look ahead, we are paying very close attention to the outlook for the global economy, with a keen focus on slowing growth in the United States and the growth rates of the emerging economies around the globe. As these emerging economies become more prosperous, they may be able to move from economies based exclusively on exports fueling their growth to more balanced models emphasizing both exports and internal consumption of the goods they produce. Over a longer period of time, we believe this creates more stability in the global economy. We are also watching rising energy and commodity prices and their impact on inflationary expectations and the absolute level of interest rates. In addition to interest rates, we are focused on the outlook for the housing market and the implications of changes in home prices on the underlying health of the financial system, believing that the recapitalization of the banking and brokerage sectors is a vitally important element of the healing process.

While market volatility is undoubtedly challenging, it can also create an environment that can result in incredibly compelling investment opportunities. Our top priority is to remain committed to our process of in-depth fundamental research, which has been at the core of our investment process since Janus’ inception in 1969. With this singular focus we strive to deliver consistent long-term results for our shareholders.

Thank you for your continued investment in Janus funds.

Sincerely,

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 their best judgment at the time this report was compiled, which was April 30, 2008. As the investing environment changes, so could the manager’s opinions. These views are unique to the manager and aren’t necessarily shared by his fellow employees or by Janus in general.

Portfolio 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 upon an investment of $1,000 invested at the beginning of the period and held for the six-month period from November 1, 2007 to April 30, 2008.

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 upon the Portfolio’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which 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, dividends, taxes and extraordinary expenses including, but not limited to, acquired fund fees and expenses to certain limits until at least March 1, 2009. 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 Portfolios’ 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 underlying funds’ redemption fees (where applicable). Redemption 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 (unaudited) Ticker: JSPGX

Portfolio 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 with approximately 80% allocated to stocks and 20% to bonds and money markets.

Dan Scherman

portfolio manager

Performance Overview

Janus Smart Portfolio – Growth returned (4.53)% for the six-month period ended April 30, 2008. That compares to a return of (9.64)% for the Portfolio’s primary benchmark, the S&P 500^® Index, during the same period. The Portfolio also fared better than its secondary benchmark, the Growth Allocation Index – a hypothetical combination of unmanaged indices – which returned (6.91)%. This internally-calculated index combines the total returns from the Dow Jones Wilshire 5000 Index (50%), the Morgan Stanley Capital International (MSCI) EAFE^® Index (25%), the Lehman Brothers Aggregate Bond Index (20%) and the MSCI Emerging Markets Free Index^SM (5%). The outperformance was consistent with the Portfolio’s objective, which is to seek the highest return over time consistent with a primary emphasis on growth of capital and a secondary emphasis on income.

Market Review

Many of the same issues that conspired to create last summer’s sudden spike in market volatility remained unresolved during the period, creating a challenging environment for investors. If anything, the outlook darkened somewhat during the last six months as plunging consumer confidence, a sharp decline in the U.S. dollar, a softening of the labor market and growing fears of a global recession joined the housing and mortgage market crises as the latest worries holding back the market. The result was a continued “risk aversion” trend that saw investors flee some of the more aggressive areas of the market for the perceived relative security of bonds and so-called “hard assets” like gold and commodities, which some view as a good place to ride out the storm.

Portfolio Review

This shift in attitudes about risk had a direct impact on our bond holdings. Not coincidentally, Janus Flexible Bond Fund – a fairly conservative fund and the primary way that we seek to participate in the bond market – rose 4.75% during the period to become the top performing position in our lineup. Its more aggressive counterpart, Janus High-Yield Fund, declined 1.65% in the period as investors rotated away from riskier corporate bonds and toward the calmer waters of the investment-grade and government bond markets.

Although the impacts of this rising aversion to risk were not surprising to us – even predictable with respect to our bond holdings – the impact of the market’s preference for commodities was more subtle. Skyrocketing oil prices dominated headlines in recent months, but prices of many non-energy commodities have been rising just as fast. That has provided a powerful tailwind for stocks exposed to extremely bullish trends in materials, energy and agricultural markets – themes that have helped drive performance of Janus Twenty Fund for quite some time. Largely as a result of this tailwind, Janus Twenty Fund overcame a steep decline in the stock market to post a gain of 2.39% for the six-month period amid a decidedly negative market, making it the best-performing equity fund in the Portfolio during the period.

On the other side of the ledger, many of our holdings were caught in the market’s general weakness. One example was our position in Janus Growth and Income Fund, which lost 11.83% during the period. Portfolio manager Marc Pinto, who recently took the reins from Minyoung Sohn, has many years of investment experience and has my full confidence. I have maintained a position in the fund despite this setback.

I remain similarly committed to our positions in the risk-managed large-cap growth and large-cap value funds managed by our mathematical affiliate INTECH, even though these funds have recently failed to keep pace with their benchmarks. I view periodic underperformance by these strategies as a natural occurrence and remain confident that they will continue to perform well over the longer term.

Portfolio Strategy

Although I am contemplating some modest changes to the underlying fund allocations, there were no substantial changes to the Portfolio’s 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.

6  Janus Smart Portfolios  April 30, 2008

(unaudited)

Our investment process involves setting return expectations for a broad range of possible Janus and INTECH mutual funds that the analyst team and I 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 upon the specific risk/return objective of Janus Smart Portfolio – Growth. Finally, we select our desired exposure.

At period-end, 79.6% of the Portfolio was allocated to equity funds, with the remaining 20.4% of the Portfolio invested in 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.

Thank you for investing in Janus Smart Portfolio – Growth.

Janus Smart Portfolio – Moderate (unaudited) Ticker: JSPMX

Portfolio 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.

Dan Scherman

portfolio manager

Performance Overview

Janus Smart Portfolio – Moderate returned (2.90)% for the six-month period ended April 30, 2008. That compares to a return of (9.64)% for the Portfolio’s primary benchmark, the S&P 500^® Index, during the same period. The Portfolio also fared better than its secondary benchmark, the Moderate Allocation Index – a hypothetical combination of unmanaged indices – which returned (4.20)%. This internally-calculated index combines the total returns from the Dow Jones Wilshire 5000 Index (40%), the Lehman Brothers Aggregate Bond Index (40%), the Morgan Stanley Capital International (MSCI) EAFE^® Index (18%) and the MSCI Emerging Markets Free Index^SM (2%). The outperformance was consistent with the Portfolio’s objective, which is to seek the highest return over time consistent with an emphasis on growth of capital and income.

Market Review

Many of the same issues that conspired to create last summer’s sudden spike in market volatility remained unresolved during the period, creating a challenging environment for investors. If anything, the outlook darkened somewhat during the last six months as plunging consumer confidence, a sharp decline in the U.S. dollar, a softening of the labor market and growing fears of a global recession joined the housing and mortgage market crises as the latest worries holding back the market. The result was a continued “risk aversion” trend that saw investors flee some of the more aggressive areas of the market for the perceived relative security of bonds and so-called “hard assets” like gold and commodities, which some view as a good place to ride out the storm.

Portfolio Review

This shift in attitudes about risk had a direct impact on our bond holdings. Not coincidentally, Janus Flexible Bond Fund – a fairly conservative fund and the primary way that we seek to participate in the bond market – rose 4.75% during the period to become the top performing position in our lineup. Its more aggressive counterpart, Janus High-Yield Fund, declined 1.65% in the period as investors rotated away from riskier corporate bonds and toward the calmer waters of the investment-grade and government bond markets.

Although the impacts of this rising aversion to risk were not surprising to us – even predictable with respect to our bond holdings – the impact of the market’s preference for commodities was more subtle. Skyrocketing oil prices dominated headlines in recent months, but prices of many non-energy commodities have been rising just as fast. That has provided a powerful tailwind for stocks exposed to extremely bullish trends in materials, energy and agricultural markets – themes that have helped drive performance of Janus Twenty Fund for quite some time. Largely as a result of this tailwind, Janus Twenty Fund overcame a steep decline in the stock market to post a gain of 2.39% for the six-month period amid a decidedly negative market, making it the best-performing equity fund in the Portfolio during the period.

On the other side of the ledger, many of our holdings were caught in the market’s general weakness. One example was our position in Janus Growth and Income Fund, which lost 11.83% during the period. Portfolio manager Marc Pinto, who recently took the reins from Minyoung Sohn, has many years of investment experience and has my full confidence. I have maintained a position in the fund despite this setback.

I remain similarly committed to our positions in the risk-managed large-cap growth and large-cap value funds managed by our mathematical affiliate INTECH, even though these funds have recently failed to keep pace with their benchmarks. I view periodic underperformance by these strategies as a natural occurrence and remain confident that they will continue to perform well over the longer term.

Portfolio Strategy

Although I am contemplating some modest changes to the underlying fund allocations, there were no substantial changes to the Portfolio’s strategy during the period. Janus Smart Portfolio – Moderate 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.

Janus Smart Portfolios  April 30, 2008  11

Janus Smart Portfolio – Moderate (unaudited)

Our investment process involves setting return expectations for a broad range of possible Janus and INTECH mutual funds that the analyst team and I 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 upon the specific risk/return objective of Janus Smart Portfolio – Moderate. Finally, we select our desired exposure.

At period-end, 59.1% of the Portfolio was allocated to equity funds, with the remaining 40.9% of the Portfolio invested in 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.

Thank you for investing in Janus Smart Portfolio – Moderate.

Performance Overview

Janus Smart Portfolio – Conservative returned (0.92)% for the six-month period ended April 30, 2008. That compares to a return of (9.64)% for the Portfolio’s primary benchmark, the S&P 500^® Index, during the same period. The Portfolio also fared better than its secondary benchmark, the Conservative Allocation Index – a hypothetical combination of unmanaged indices – which returned (1.47)%. This internally-calculated index combines the total returns from the Lehman Brothers Aggregate Bond Index (60%), the Dow Jones Wilshire 5000 Index (28%) and the Morgan Stanley Capital International (MSCI) EAFE^® Index (12%). The outperformance was consistent with the Portfolio’s objective, which is to seek the highest return over time consistent with a primary emphasis on income and a secondary emphasis on growth of capital.

Not coincidentally, Janus Flexible Bond Fund – a fairly conservative fund that represents more than half of the Portfolio’s net assets – rose 4.75% during the period to become the top performing position in our lineup. Its more aggressive counterpart, Janus High-Yield Fund, declined 1.65% in the period as investors rotated away from riskier corporate bonds and toward the calmer waters of the investment-grade and government bond markets. Our position in Janus Short-Term Bond Fund, which rounds out our exposure to fixed-income markets, held its own by turning in a gain of 2.39% for the six-month period.

On the other side of the ledger, all of our equity fund holdings were caught in the market’s downdraft and finished the period lower. Notably, however, all but three performed better than their respective benchmarks – a fact that gives me additional confidence in the decision to allocate a portion of the Portfolio to them.

However, some holdings failed to keep pace. One example was our position in Janus Growth and Income Fund, which lost 11.83% during the period.

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. Performance of Janus Smart Portfolios depends on that of the underlying funds. They are subject to the volatility of the financial markets in the U.S. and abroad and to the additional risks associated with investments.

Returns include reinvestment of dividends from net investment income and distributions from capital gains. The returns shown do not reflect the deduction of taxes that a shareholder would pay on Portfolio distributions or the redemption of Portfolio shares.

Lipper, a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Rankings are historical with capital gains and dividends reinvested.

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

See Notes to Schedules of Investments for index definitions.

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

Portfolio Expenses

The example below shows you the ongoing costs (in dollars) of investing in your Portfolio and allows you to compare these costs with those of other mutual funds. Please refer to the section Useful Information About Your Portfolio Report for a detailed explanation of the information presented in this chart.

	Beginning Account Value		Ending Account Value		Expenses Paid During Period
Expense Example	(11/1/07)		(4/30/08)		(11/1/07- 4/30/08)†
Actual	$	1,000.00	$	990.80	$	0.89
Hypothetical (5% return before expenses)	$	1,000.00	$	1,023.97	$	0.91

† Expenses are equal to the annualized expense ratio of 0.18%, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the one-half year period).

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 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 is 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 twenty-nine funds. Each Portfolio 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 Equity Securities

INTECH RISK-MANAGED STOCK FUND seeks long-term growth of capital. The fund invests, under normal circumstances, at least 80% of its net assets in common stocks from the universe of the fund’s benchmark, which is the S&P 500^® Index. Stocks are selected for their potential contribution to the long-term growth of capital, utilizing INTECH’s mathematical investment process.

JANUS ADVISER BALANCED FUND – CLASS I and JANUS BALANCED FUND seek long-term capital growth, consistent with preservation of capital and balanced by current income. Each fund pursues its investment objective by normally investing 50-60% of its assets in equity securities selected primarily for their growth potential and 40-50% of its assets in securities selected primarily for their income potential. Each fund normally invests at least 25% of its assets in fixed-income senior securities.

JANUS ADVISER CONTRARIAN FUND – CLASS I and JANUS CONTRARIAN FUND seek long-term growth of capital. Each fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets in equity securities with the potential for long-term growth of capital. The portfolio manager emphasizes investments in companies with an attractive price/free cash flow, which is the relationship between the price of a stock and the company’s available cash from operations minus capital expenditures. The portfolio manager will typically seek attractively valued companies that are improving their free cash flow and returns on invested capital. Such companies may also include special situations companies that are experiencing management changes and/or are currently out of favor.

JANUS ADVISER FORTY FUND – CLASS I seeks long-term growth of capital. The fund pursues its investment objective by normally investing primarily in a core group of 20-40 common stocks selected for their growth potential. The fund may invest in companies of any size, from larger, well-established companies to smaller, emerging growth companies.

JANUS ADVISER FUNDAMENTAL EQUITY FUND – CLASS I and JANUS FUNDAMENTAL EQUITY FUND seek long-term growth of capital. Each fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets in equity securities selected for their growth potential. Eligible equity securities in which each fund may invest include: (i) domestic and foreign common stocks; (ii) preferred stocks; (iii) securities convertible into common stocks or preferred stocks such as convertible preferred stocks, bonds, and debentures; and (iv) other securities with equity characteristics (including the use of swaps). Each fund may invest in companies of any size.

JANUS ADVISER GLOBAL REAL ESTATE FUND – CLASS I seeks total return through a combination of capital appreciation and current income. The fund invests, under normal circumstances, at least 80% of its net assets plus the amount of any borrowings for investment purposes, in equity and debt securities of real estate-related companies. Such companies may include those in the real estate industry or real estate-related industries. These securities may include common stocks, preferred stocks and other equity securities, including, but not limited to, real estate investment trusts (REITs) and similar REIT-like entities. As a

fundamental policy, the fund will concentrate 25% or more of its net assets in securities of issuers in real estate or real estate-related industries. The fund’s investment in companies engaged in businesses outside the real estate industry which possess significant real estate holdings will be deemed to be in the real estate industry for purposes of the fund’s investment objective and its policy on industry concentration. The fund expects under normal market conditions to maintain investments in issuers from several different developed countries, including the United States. Under unusual circumstances, the fund may invest all of its assets in a single country. The fund may invest in emerging markets, but will normally limit such investments to 15% of its net assets, measured at the time of purchase. Within the parameters of its specific investment policies, the fund may invest in foreign equity and debt securities.

Investments in Fixed-Income Securities

JANUS ADVISER FLEXIBLE BOND FUND – CLASS I and JANUS FLEXIBLE BOND FUND seek to obtain maximum total return, consistent with preservation of capital. Each fund pursues its investment objective by primarily investing, under normal circumstances, at least 80% of its assets in bonds. Bonds include, but are not limited to, government bonds, corporate bonds, convertible bonds, mortgage-backed securities, and zero-coupon bonds. Each fund will invest at least 65% of its assets in investment grade debt securities and will maintain an average-weighted effective maturity of five to ten years.

30  Janus Smart Portfolios  April 30, 2008

rate loans, the fund may invest in other types of securities including, but not limited to, unsecured floating rate loans, subordinated or junior debt, corporate bonds, U.S. Government securities, mortgage-backed and other asset-backed securities, repurchase agreements, certain money market instruments, high-yield/high-risk bonds, and other instruments (including synthetic or hybrid) that pay interest at rates that adjust whenever a specified interest rate changes and/or reset on predetermined dates. The fund’s investments in floating rate securities are generally rated below investment grade or are unrated and have characteristics considered below investment grade.

JANUS ADVISER HIGH-YIELD FUND – CLASS I and JANUS HIGH-YIELD FUND seek to obtain high current income. Capital appreciation is a secondary objective when consistent with its primary objective. Each fund pursues its investment objectives by investing, under normal circumstances, at least 80% of its net assets in high-yield/high-risk securities rated below investment grade. Securities rated below investment grade may include their unrated equivalents or other high-yielding securities the portfolio manager believes offer attractive risk/return characteristics. Each fund may at times invest all of its assets in such securities.

JANUS SHORT-TERM BOND FUND seeks as high a level of current income as is consistent with preservation of capital. The fund invests, under normal circumstances, at least 80% of its net assets in short- and intermediate-term securities such as corporate bonds or notes or government securities, including agency securities. The fund may invest up to 35% of its net assets in high-yield/high risk bonds. The fund expects to maintain an average-weighted effective maturity of three years or less under normal circumstances.

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. The fund also intends to invest in repurchase agreements.

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 of the underlying funds 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 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 held by the underlying funds 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 utilizing 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 the 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 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 underlying funds’ Trustees. Circumstances in which fair value pricing may be utilized include, but are not limited to: (i) when significant events occur which may affect the securities of a single issuer, such as mergers, bankruptcies, or significant issuer specific developments; (ii) when significant events occur which may affect an entire market, such as natural disasters or significant governmental actions; and (iii) when non-significant events

Janus Smart Portfolios  April 30, 2008  31

Notes to Financial Statements (unaudited) (continued)

occur such as markets closing early or not opening, security trading halts, or pricing of non-valued securities and restricted or nonpublic securities. 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. Dividends from foreign securities may be subject to withholding taxes in foreign jurisdictions. 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 as well as a portion of general expenses, which may be allocated pro rata to each of the funds or Portfolios in the Trust. 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.

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. Janus Capital Management LLC (“Janus Capital”) makes efforts to balance the benefits and risks from granting such loans.

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 if time permits. 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, time deposits, repurchase agreements, money market mutual funds or other money market accounts, 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.

Dresdner Bank AG (the “Lending Agent”) may also invest the cash collateral in the Allianz Dresdner Daily Asset Fund 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 loaned 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 underlying funds’ direction to the Lending Agent. The Lending Agent may retain a portion of the interest earned on the cash collateral invested. The cash collateral invested by the Lending Agent is disclosed in the Schedule of Investments (if applicable).

Interfund Lending

Pursuant to an exemptive order received from the SEC, the underlying funds may be party to interfund lending agreements 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 the borrowing underlying 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, except INTECH Risk-Managed Stock Fund, Janus Adviser INTECH Risk-Managed Core Fund, Janus Adviser INTECH Risk-Managed Growth Fund, Janus Adviser INTECH Risk-Managed International Fund, Janus Adviser INTECH Risk-Managed Value Fund (together, the “Risk-Managed funds”) and Janus Money Market Fund, may enter into forward currency contracts in order to reduce exposure to changes in foreign currency exchange rates on foreign portfolio holdings of the underlying funds 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

32  Janus Smart Portfolios  April 30, 2008

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.

Futures Contracts

The underlying funds, except Janus Money Market Fund, may enter into futures contracts to gain exposure to the stock market pending investment of cash balances or to meet liquidity needs. The underlying funds may also 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 values 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 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 designated as collateral for market value on futures contracts. Such collateral is in the possession of the underlying funds’ custodian.

Swaps

The underlying funds, except the Risk-Managed funds and Janus Money Market Fund, may enter into swap agreements to hedge their exposure to interest rates and credit risk or for investment purposes. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other.

Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the swap contract. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the underlying funds, and/or the termination value. Therefore, the underlying funds consider the creditworthiness of each counterparty to a swap contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities.

Options Contracts

The underlying funds, except Janus Money Market Fund, may purchase or write put and call options on futures contracts and on portfolio securities for hedging purposes or as a substitute for an investment. The underlying funds, except the Risk-Managed funds and Janus Money Market Fund, may also purchase or write put and call options on foreign currencies in a manner similar to that in which futures or forward contracts on foreign currencies will be utilized. The underlying funds may also invest in Long-Term Equity Anticipation Securities (LEAPS), which are long-term option contracts that can be maintained for a period up to three years. 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.

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 are adjusted by the amount of premium received or paid by the underlying funds.

The underlying funds may also purchase and write exchange-listed and over-the-counter put and call options on domestic securities indices, and on foreign securities indices listed on domestic and foreign securities exchanges. Options on securities indices are similar to options on securities except that (1) the expiration cycles of securities index options are monthly, while those of securities options are currently quarterly, and (2) the delivery requirements are different. Instead of giving the right to take or make delivery of securities at a specified price, an option on a securities index gives the holder the right to receive a cash “exercise settlement amount” equal to (a) the amount, if any, by which the fixed exercise price of the option exceeds (in the case of a put) or is less than (in the case of a call) the closing value of the underlying index on the date of exercise, multiplied by (b) a fixed “index multiplier.” Receipt of this cash amount will depend upon the closing level of the securities index upon which the option is based being greater than, in the case of a call, or less than, in the case of a put, the exercise price of the index and the exercise price of the option times a specified multiple. The writer of the option is obligated, in return for the premium received, to make delivery of this amount.

The risk in writing call options is that the underlying funds give up the opportunity for profit if the market price of the security

Janus Smart Portfolios  April 30, 2008  33

Notes to Financial Statements (unaudited) (continued)

increases and the option is exercised. The risk in writing put options 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 options 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 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. There is no limit to the loss the underlying funds may recognize due to written call options.

Mortgage Dollar Rolls

The underlying funds, Janus Adviser Global Real Estate Fund, Janus Adviser Long/Short Fund, Janus Adviser Flexible Bond Fund, Janus Flexible Bond Fund, Janus Adviser Floating Rate High Income Fund, Janus Adviser High-Yield 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 funds sell a mortgage-related security (such as a Government National Mortgage Association (“Ginnie Mae”) 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 funds 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 funds.

The underlying funds’ 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 funds, maintained in a segregated account. To the extent that the underlying funds collateralize their 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 portfolio managers’ 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 funds, Janus Adviser Flexible Bond Fund, Janus Flexible Bond Fund, Janus Adviser Floating Rate High Income Fund, Janus Adviser High-Yield 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 funds commit 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 Ginnie Mae, Federal National Mortgage Association (“Fannie Mae”) and/or Federal Home Loan Mortgage Corporation (“Freddie Mac”) transactions.

Securities purchased on a TBA basis are not settled until they are delivered to the underlying funds, normally 15 to 45 days later. Beginning on the date the underlying funds enter 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.

Floating Rate Loans

The underlying funds, Janus Adviser Balanced Fund, Janus Balanced Fund, Janus Adviser Long/Short Fund, Janus Adviser Flexible Bond Fund, Janus Flexible Bond Fund, Janus Adviser Floating Rate High Income Fund, Janus Adviser High-Yield Fund, Janus High-Yield Fund and Janus Short-Term Bond Fund, may invest in floating rate loans. Floating rate loans are debt securities that have floating interest rates which adjust periodically and are tied to a benchmark lending rate such as the London Interbank Offered Rate (“LIBOR”). LIBOR is a short-term interest rate that banks charge one another and that is generally representative of the most competitive and current cash rates. In other cases, the lending rate could be tied to the prime rate offered by one or more major U.S. banks or the rate paid on large certificates of deposit traded in the secondary markets. If the benchmark lending rate changes, the rate payable to lenders under the loan will change at the next scheduled adjustment date specified in the loan agreement. Floating rate loans are typically issued to companies (“borrowers”) in connection with recapitalizations, acquisitions, and refinancings. Floating rate loan investments are generally below investment grade. Senior floating rate loans are secured by specific collateral of a borrower and are senior in the borrower’s capital structure. The senior position in the borrower’s capital structure generally gives holders of senior loans a claim on certain of the borrower’s assets that is senior to subordinated debt and preferred and common stock in the case of a borrower’s default. Floating rate loan investments may involve foreign borrowers, and investments may be denominated in foreign currencies. Floating rate loans often involve borrowers whose financial condition is troubled or uncertain and companies

34  Janus Smart Portfolios  April 30, 2008

that are highly leveraged. The underlying funds may invest in obligations of borrowers who are in bankruptcy proceedings. Floating rate loans may include fully funded term loans or revolving lines of credit.

Bank Loans

The underlying funds, Janus Adviser Balanced Fund, Janus Balanced Fund, Janus Adviser Long/Short Fund, Janus Adviser Flexible Bond Fund, Janus Flexible Bond Fund, Janus Adviser Floating Rate High Income Fund, Janus Adviser High-Yield 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 funds have 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 funds generally have 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 funds invest generally are readjusted periodically to an increment over a designated benchmark rate, such as the one-month, three-month, six-month, or one-year LIBOR.

The underlying funds 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 funds 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 funds utilize an independent third party to value individual bank loans on a daily basis.

Short Sales

The underlying funds, except the Risk-Managed funds, may engage in “short sales against the box.” Short sales against the box involve either selling short a security that the underlying funds own, or selling short a security 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. The underlying funds do not deliver from their portfolio the securities sold short and do not immediately receive the proceeds of the short sale. The underlying funds borrow the securities sold short and receives proceeds from the short sale only when it delivers the securities to the lender. 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 the Risk-Managed funds and Janus Money Market Fund, may also engage in other short sales. The underlying funds may engage in short sales when the portfolio managers and/or investment personnel anticipate that a security’s market purchase price will be less than its borrowing price. To complete the transaction, the underlying funds must borrow the security to deliver it to the purchaser and buy that same security in the market to return it to the lender. The total market value of all of the underlying funds’ short sales positions will not exceed 10% of their net assets. Although the potential for gain as a result of a short sale is limited to the price at which the underlying funds sold the security short less the cost of borrowing the security, the 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 funds 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 to the size of any loss that the underlying funds may recognize upon termination of a short sale. Short sales held by the underlying funds are fully collateralized by other securities.

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 translations arises 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 foreign security transactions and income.

Foreign currency-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

Janus Smart Portfolios  April 30, 2008  35

Notes to Financial Statements (unaudited) (continued)

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.

Exchange-Traded Funds

The underlying funds, except Janus Money Market Fund, may invest in exchange-traded funds, which are index-based investment companies which hold substantially all of their assets in securities with equity characteristics. As a shareholder of another investment company, the underlying fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the underlying fund bears directly in connection with its own operations.

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 non-registered 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

The underlying funds, except Janus Money Market Fund, 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.

Additional Investment Risk

The underlying funds, particularly Janus Adviser Flexible Bond Fund, Janus Flexible Bond Fund, Janus Adviser Floating Rate High Income Fund, Janus Adviser High-Yield Fund, Janus High-Yield 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. The Risk-Managed funds does not intend to invest in high-yield/high-risk bonds.

Restricted Security Transactions

Restricted securities held by the underlying funds may not be sold except in exempt transactions or in a public offering registered under the Securities Act of 1933, as amended. 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 the underlying funds 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 of net investment income and realized capital gains (if any) are generally declared and distributed annually. The majority of dividends and capital gains distributions from a Portfolio may be automatically reinvested into additional shares of that Portfolio, based upon 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 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.

The Portfolios adopted the provisions of Financial Accounting Standards Board (“FASB”) Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes on April 30, 2008. FIN 48 requires an evaluation of tax positions taken (or expected to be taken) in the course of preparing a Portfolio’s tax return to determine whether these positions meet a “more-likely-than-not” standard that based on the technical merits have a more than fifty percent likelihood of being sustained by a taxing authority upon examination. A tax position that meets the “more-likely-than-not” recognition

36  Janus Smart Portfolios  April 30, 2008

threshold is measured to determine the amount of benefit to recognize in the financial statements. The Portfolios recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations.

FIN 48 requires management of the Portfolios to analyze all open tax years, fiscal years 2003-2006 as defined by Statute of Limitations, for all major jurisdictions, including federal tax authorities and certain state tax authorities. As of and during the six-month period ended April 30, 2008, the Portfolios did not have a liability for any unrecognized tax benefits. The Portfolios have no examination in progress and are not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

New Accounting Pronouncements

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS No. 157”), which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS No. 157 does not require new fair value measurements, but is applied to the extent that other accounting pronouncements require or permit fair value measurements. SFAS No. 157 emphasizes that fair value is a market-based measurement that should be determined based on the assumptions that market participants would use in pricing an asset or liability. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. Management does not believe the adoption of SFAS No. 157 will impact the financial statement amounts; however, the Portfolios will be required to disclose the extent to which fair value is used to measure assets and liabilities and the inputs used to develop the measurements.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS No. 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. SFAS No. 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. SFAS No. 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. Management does not believe the adoption of SFAS No. 159 will impact the financial statement amounts.

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS No. 161”), which requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. SFAS No. 161 is effective for financial statements issued for fiscal years beginning after November 15, 2008, and interim periods within those fiscal years. Management is in the process of evaluating the impact of SFAS No. 161 on the Portfolios’ financial statement disclosures.

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 shown in the table below:

	Advisory
Portfolio	Fee %
Janus Smart Portfolio — Growth		0.05%
Janus Smart Portfolio — Moderate		0.05%
Janus Smart Portfolio — Conservative		0.05%

Janus Capital has agreed until at least March 1, 2009 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, dividends, taxes and extraordinary expenses including, but not limited to, acquired fund fees and 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 reimbursement upon termination of the current advisory agreements. For the six-month period ended April 30, 2008, total reimbursement by Janus Capital and the recoupment that

Janus Smart Portfolios  April 30, 2008  37

Notes to Financial Statements (unaudited) (continued)

may be potentially made to Janus Capital are indicated in the table below:

Portfolio	Reimbursement		Total Recoupment
Janus Smart Portfolio — Growth	$	–	$	46,539
Janus Smart Portfolio — Moderate		–		99,565
Janus Smart Portfolio — Conservative		9,020		129,731

For the six-month period ended April 30, 2008, total previously waived recoupment received by Janus Capital was $29,338 and $3,006 for Janus Smart Portfolio – Growth and Janus Smart Portfolio – Moderate, respectively.

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.

The Board of Trustees has adopted a deferred compensation plan (the “Deferred 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 are credited to the account. The fluctuation of the account balance is recorded by the Portfolios as unrealized appreciation/(depreciation) and is shown as of April 30, 2008 on the Statement of Assets and Liabilities as an asset, “Non-interested Trustees’ deferred compensation,” and a liability, “Non-interested Trustees’ deferred compensation fees.” Additionally, the recorded unrealized appreciation/(depreciation) is included in “Unrealized net appreciation/(depreciation) of investments, foreign currency translations and non-interested Trustees’ deferred compensation” on the Statement of Assets and Liabilities. Deferred compensation expenses for the six-month period ended April 30, 2008 are included in “Non-interested Trustees’ fees and expenses” on the Statement of Operations. Trustees are allowed to change their designation of mutual funds from time to time. Amounts will be deferred until distributed in accordance with the Deferred Plan. No deferred fees were paid to any Trustee under the Deferred Plan during the six-month period ended April 30, 2008.

During the six-month period ended April 30, 2008, Janus Services reimbursed the following Portfolios as a result of dilutions caused by incorrectly processed shareholder activity.

Portfolio
Janus Smart Portfolio — Growth	$	8,030
Janus Smart Portfolio — Moderate		7,728
Janus Smart Portfolio — Conservative		929

During the fiscal year ended October 31, 2007, Janus Services reimbursed the following Portfolios as a result of dilutions caused by incorrectly processed shareholder activity.

Portfolio
Janus Smart Portfolio — Growth	$	121
Janus Smart Portfolio — Conservative		716

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 Trust. Total compensation of $39,907 was paid by the Trust during the six-month period ended April 30, 2008. Each Portfolio’s portion is reported as part of “Other Expenses” on the Statement of Operations.

3.  Purchases and Sales of Investment Securities

For the six-month period ended April 30, 2008, the aggregate cost of purchases and proceeds from sales of investment securities (excluding short-term securities and options contracts) were as follows:

Janus Smart Portfolio — Conservative		34,298,254		3,622,865		–		–

4.  Federal Income Tax

Income and capital gains distributions are determined in accordance with income tax regulations that may differ from accounting principles generally accepted in the United States of America. These differences are due to differing treatments for items such as net short-term gains, deferral of wash sale losses, foreign currency transactions, net investment losses and capital loss carryovers.

The Funds have elected to treat gains and losses on forward foreign currency contracts as capital gains and losses. Other foreign currency gains and losses on debt instruments are treated as ordinary income for federal income tax purposes pursuant to Section 988 of the Internal Revenue Code.

The aggregate cost of investments and the composition of unrealized appreciation and depreciation of investment securities for federal income tax purposes as of April 30, 2008 are noted below.

Unrealized appreciation and unrealized depreciation in the table below exclude appreciation/depreciation on foreign currency translations. The primary difference between book and tax appreciation or depreciation of investments is wash sale loss deferrals.

	Federal Tax		Unrealized		Unrealized		Net Tax
Portfolio	Cost		Appreciation		(Depreciation)		Appreciation
Janus Smart Portfolio — Growth	$	188,645,812	$	15,493,721	$	(4,126,947)	$	11,366,774

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. A 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, 2008, the Portfolios recorded distributions from affiliated investment companies as dividend income and had the following affiliated purchases and sales:

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 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. The appeal is still pending and argument in the matter was held in December 2007. 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. However, in June 2007, Plaintiffs appealed that dismissal to the United States Court of Appeals for the Fourth Circuit. That appeal is currently pending.

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 status conference was held on June 28, 2007, during which the parties were ordered to submit their proposed scheduling order. To date, no scheduling order has been entered in the case. In addition to the pending Motion to Discharge Order to Show Cause, 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.

During 2007, two lawsuits were filed against Janus Management Holdings Corporation (“Janus Holdings”), an affiliate of JCGI, by former Janus portfolio managers, alleging that Janus Holdings unilaterally implemented certain changes to compensation in violation of prior agreements. These complaints allege some or all of the following claims: (1) breach of contract; (2) willful and wanton breach of contract; (3) breach of good faith and fair dealing; and (4) estoppel. Janus Holdings filed Answers to these complaints denying any liability for these claims and intends to vigorously defend against the allegations.

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

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

The Trustees of Janus Investment Fund, none of whom has ever been affiliated with Janus Capital (“Independent Trustees”), oversee the management of each Fund 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 Fund, 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 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 with management to consider the agreements, and also met separately in executive session with their independent legal counsel and their independent fee consultant.

At a meeting held on December 14, 2007, based on their evaluation of the information provided by Janus Capital, the subadvisers and the independent fee consultant, as well as other information, the Trustees determined that the overall arrangements between each Fund and Janus Capital and each subadviser, as applicable, 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 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, 2008 through February 1, 2009 (January 1, 2008 through January 1, 2009 for INTECH Risk-Managed Stock Fund and Janus Global Research Fund), subject to earlier termination as provided for 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, the knowledge of 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 and/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 those Funds whose performance lagged that of the median of their peers for certain periods, the quality of those services had been

42  Janus Smart Portfolios  April 30, 2008

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 well-qualified personnel.

Performance of the Funds

The Trustees considered the investment performance 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 many 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 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, 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.

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 fee rates for Funds having a similar strategy, the Trustees noted that, under the terms of 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, the Trustees 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.

The Trustees reviewed information on the profitability to Janus Capital and its affiliates of their relationships with each Fund, as well as an explanation of the methodology used in allocating various expenses of Janus Capital and its affiliates among the Funds and other clients. They 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 receives adequate incentives to manage the Funds effectively. They 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 adviser, 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 payable by Janus Capital or the Funds to the subadvisers of subadvised Funds, were reasonable in relation to the nature, extent 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 subadvisers charge to other clients. They 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

Additional Information (unaudited) (continued)

Funds because they have not reached adequate scale. Moreover, as the assets of many of the Funds declined in the past few years, those 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. They also considered Janus Capital’s past and proposed use of commissions paid by Funds on their portfolio brokerage transactions to obtain proprietary and third-party research products and services benefiting those Funds and/or other clients of Janus Capital. The Trustees concluded that Janus Capital’s use of “soft” commission dollars of a Fund to obtain proprietary and third-party 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 also concluded that Janus Capital benefits from the receipt of proprietary and third-party 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, all of whom are 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.

Explanations of Charts, Tables and
Financial Statements (unaudited)

1.  Performance Overviews

Performance overview graphs compare the performance of a hypothetical $10,000 investment in each Portfolio (from inception) 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 dividends and distributions, 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, 2007. 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 will 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 currency transactions, 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 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 and prospectuses. Expense offsets and expense reimbursements, if any, are also shown.

The last section lists the increase or decrease in the value of securities held in the Portfolios. The 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

Janus Smart Portfolios  April 30, 2008  45

Explanations of Charts, Tables and
Financial Statements (unaudited) (continued)

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 will notice that dividend distributions had little effect on each Portfolio’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 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 each Portfolio’s net asset value (“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 average 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 frequency of dividend payments and the extent of foreign investments, which entail greater transaction costs.

The Portfolios’ 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 offset (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 market conditions, changes in the asset size of a Portfolio, the nature of the Portfolio’s investments, changes in the target allocation 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.

Janus provides access to a wide range of investment disciplines.

Asset Allocation

Janus asset allocation portfolios 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.
