Top Questions from Shareholders Dick Weil Chief Executive Officer Bruce Koepfgen Chief Financial Officer

Could you provide additional color on this quarter’s increase in outflows? Absence of large redemption ($1.2 billion in 1Q 2013) Outflow trend continued at 1Q 2013 level Challenging market conditions Performance challenges and PM changes led to increased redemptions and lower sales Note: Long-term flows exclude money market flows. $(3.9) $(5.4) $1.2 $0.1 $(0.2) $(2.6) 1Q 2013 Long-Term Net Outflows INTECH Perkins Janus FI Janus Equity 2Q 2013 Long-Term Net Outflows 1Q 2013 vs. 2Q 2013 Long - Term Net Outflows - Change by Advisor (1) ($ in billions) (1)

Please explain the quarter-over-quarter change in EPS Operating income increased 7% over 1Q 2013 due to higher average assets and expense management We recognized a $12.6 million non-cash loss on the early extinguishment of debt related to the 2014 Convertible Senior Note exchange Primarily consists of mark-to-market losses on our $341 million seed portfolio ($0.02 per share gain in 1Q 2013 and $0.02 per share loss in 2Q 2013) $0.08 $0.04 $0.04 $0.01 $0.15 $0.00 $0.05 $0.10 $0.15 $0.20 1Q 2013 EPS Operating Income Loss on Early Extinguishment of Debt Net Investment Gains / Losses and Other Non- Operating Expenses 2Q 2013 EPS

Could you provide additional color around the convertible exchange and why you did it? Pricing and Terms on 2018 Convertible Senior Notes The exchange of our 2014 Convertible Notes took advantage of favorable market dynamics, which allowed us to reduce our interest expense, extend our existing maturities and increase our financial flexibility Expected interest expense savings of $3.5 million in 2013 In conjunction with the exchange, the note hedge and warrant transaction we entered into will reduce the potential for future dilution to existing shareholders by effectively increasing the conversion premium on the new notes to 45% from 25%, or $12.60 per share Janus Capital Group Inc.

Notes: The funds listed have a performance-based investment advisory fee that adjusts upward or downward based on each fund’s performance relative to an approved benchmark index over a performance measurement period. Please see the funds’ Statements of Additional Information for more details. Actual performance measurement periods used for calculating the performance fees are from 12 months up to 36 months, and then over 36-month rolling periods. Adjustment of ± 15 bps assumes constant assets and could be higher or lower depending on asset fluctuations. The performance measurement period began on 2/1/2006, and the performance adjustment was implemented as of 2/1/2007. Effective close of business on March 15, 2013, Janus Global Research Fund merged with and into Janus Worldwide Fund; following the merger, Janus Worldwide Fund was renamed Janus Global Research Fund (the “Combined Fund”). The Combined Fund’s surviving performance track record is that of the former Janus Global Research Fund, and the performance measurement benchmark is the MSCI World Index. For three years after the merger, Janus will waive its management fee to at least a level that is equivalent to the fee rate the Combined Fund would have paid if, after the merger, the performance history of Janus Worldwide Fund were used to calculate the performance fee adjustment to the base management fee. The performance measurement period began on 12/1/2007 and the performance adjustment was implemented as of 12/1/2008. Beginning 7/1/2010, Janus Global Real Estate Fund’s benchmark index changed from the FTSE EPRA/NAREIT Developed Index to the FTSE EPRA/NAREIT Global Index for purposes of measuring the Fund’s performance and calculating the performance adjustment. Because the Fund’s performance adjustment is based upon a rolling 36-month performance measurement period, comparisons to the FTSE EPRA/NAREIT Global Index will not be fully implemented until 36 months after July 1, 2010. During this transition period, the Fund's returns will be compared to a blended index return. The performance measurement period began on 12/1/2006, and the performance adjustment was implemented as of 12/1/2007. The performance measurement period began on 1/1/2006, and the performance adjustment was implemented as of 1/1/2007. Effective 12/7/11, INTECH Risk-Managed Core Fund was renamed INTECH U.S. Core Fund. The performance measurement period began on 1/1/2009, and the performance adjustment was implemented as of 1/1/2010. The performance measurement period began on 7/1/2010, and the performance adjustment was implemented as of 6/30/2011. Effective 7/1/10, Janus Global Opportunities Fund was renamed Perkins Global Value Fund. The performance measurement period began on 7/1/2010, and the performance adjustment was implemented as of 9/30/2011. The performance measurement period began on 8/1/2010, and the performance adjustment was implemented as of 10/31/2011. The performance measurement period began on 7/1/2010, and the performance adjustment was implemented as of 12/31/2011. The performance measurement period began on 12/31/2010, and the performance adjustment was implemented as of 12/31/2011.

For the period ending June 30, 2013, 60%, 75%, 50% and 67% of the mathematical equity mutual funds were beating their benchmarks on a 1-, 3-, 5-year and since-fund inception basis. Funds included in the analysis and their inception dates are: INTECH U.S. Growth Fund – Class S (1/03); INTECH U.S. Core Fund – Class T (2/03); INTECH U.S. Value Fund – Class I (12/05); INTECH International Fund – Class I (5/07); INTECH Global Dividend Fund – Class I (12/11) and Janus INTECH U.S. Low Volatility Portfolio – Service Shares (9/12). The proprietary mathematical process used by INTECH may not achieve the desired results. Since the portfolios are 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. Past performance cannot guarantee future results. Investing involves risk, including the possible loss of principal and fluctuation of value. Performance results reflect the reinvestment of dividends and other earnings. Composite performance results shown are time-weighted rates of return using daily valuation, include the effect of transaction costs (commissions, exchange fees, etc.), and are gross of non-reclaimable withholding taxes, if any. The composites include all actual fee-paying accounts managed on a fully discretionary basis according to the investment strategy from inception date, including those no longer under management. Portfolios meeting such criteria enter the composite upon the full first month under management. Reporting currency is USD, unless otherwise noted. The gross performance results presented do not reflect the deduction of investment advisory fees. Returns will be reduced by such advisory fees and other contractual expenses as described in each client’s individual contract. The net performance results do not reflect the deduction of investment advisory fees actually charged to the accounts in the composite. However, the net performance results do reflect the deduction of model investment advisory fees. Through 12/31/04, net returns were derived using the maximum fixed fee in effect for each strategy. As of 1/1/05, net returns are calculated by applying the standard fee schedule in effect for the respective period to each account in the composite on a monthly basis. Actual advisory fees may vary among clients invested in this strategy. Actual advisory fees paid may be higher or lower than model advisory fees. Some clients may utilize a performance-based fee. For U.S. Large Cap Growth from inception to 12/31/05, the composite’s benchmark was the S&P 500/Barra Growth Index (“Barra Growth Index”). In 2005, S&P announced index name and methodology changes affecting the Barra Growth Index, which later became the S&P 500/Citigroup Growth Index (“Citigroup Growth Index”). During the transitional period, from 1/1/06 to 3/31/06, the benchmark return consisted partially of the return of the Barra Growth Index and the Citigroup Growth Index. On 4/1/06, the composite’s benchmark was changed to the Citigroup Growth Index. Effective 12/9/2009, the Citigroup Growth Index's name was changed to S&P 500 Growth Index. The S&P 500 Growth Index is a market-capitalization-weighted index developed by Standard and Poor's consisting of those stocks within the S&P 500 Index that exhibit strong growth characteristics. The index measures the performance of the growth style of investing in large cap U.S. stocks. The S&P 500 Growth Index will be reconstituted annually. For U.S. Large Cap Value from inception to 12/31/05, the composite’s benchmark was the S&P 500/Barra Value Index (“Barra Value Index”). In 2005, S&P announced index name and methodology changes affecting the Barra Value Index, which later became the S&P 500/Citigroup Value Index (“Citigroup Value Index”). During the transitional period, from 1/1/06 to 3/31/06, the benchmark return consisted partially of the return of the Barra Value Index and the Citigroup Value Index. On 4/1/06, the composite’s benchmark was changed to the Citigroup Value Index. Effective 12/9/2009, the Citigroup Value Index's name was changed to S&P 500 Value Index. The S&P 500 Value Index is a market-capitalization-weighted index developed by Standard and Poor’s consisting of those stocks within the S&P 500 Index that exhibit strong value characteristics. The index measures the performance of the value style of investing in large cap U.S. stocks. The S&P 500 Value Index will be reconstituted annually. Prior to May 21, 2010, with respect to non-U.S. securities traded on non-U.S. exchanges, INTECH used fair value prices that reflected current market conditions at the end of regular trading hours of the NYSE, normally 4:00 PM ET, rather than unadjusted closing prices in local markets. Therefore, the prices as well as foreign exchange rates used to calculate the U.S. dollar market values of securities may have differed from those used by an index. Indices typically use the unadjusted closing price in local markets instead of fair value pricing. As of May 21, 2010, prices for non-U.S. securities traded on non-U.S. exchanges are valued as of the close of their respective local markets. Non-U.S. securities are translated into U.S. dollars using the 4:00 PM London spot rate. Non-U.S. investments are subject to certain risks of overseas investing, including currency fluctuations and changes in political and economic conditions, which could result in significant market fluctuations. With respect to European Large Cap Core, prices assigned to investments are published prices on their primary markets or exchanges since the composite’s inception. The returns for the indices shown do not include any transaction costs, management fees or other costs and are gross of dividend tax withholdings. Mathematical equity strategies included in the investment performance summaries include only those strategies with at least a 1-year track record.

Call 877.33JANUS (52687) or visit janus.com/advisor/mutual-funds for performance, rankings and ratings current to the most recent month-end. Janus Capital Group Inc. (“JCG”) provides investment advisory services through its primary subsidiaries, Janus Capital Management LLC (“Janus”), INTECH Investment Management LLC (“INTECH”) and Perkins Investment Management LLC (“Perkins”). “Complex-Wide Mutual Funds” means all affiliated mutual funds managed by Janus, INTECH and Perkins. “Fundamental Equity Mutual Funds” means all mutual funds managed by Janus or Perkins that invest in equity securities. “Fixed Income Mutual Funds” means all mutual funds managed by Janus that invest primarily in fixed income securities. “Mathematical Equity Strategies” means all discretionary managed accounts (not mutual funds) that are advised or sub-advised by INTECH. Mutual fund relative performance analysis shown is for each Fund's initial share class: Class T, S or I Shares in the Janus retail fund (“JIF”) trust and the Institutional or Service Shares in the Janus Aspen Series (“JAS”). These share classes may not be eligible for purchase by all investors. Other share classes may have higher sales and management fees, which can result in differences in performance. Morningstar Comparative Performance Morningstar performance on an asset-weighted basis is calculated by taking all funds and assigning the assets under management ("AUM") in each respective fund to either the 1st, 2nd, 3rd or 4th quartile bucket based on each fund's respective Morningstar relative ranking. The total AUM of each quartile’s bucket is then divided by complex-wide total AUM to arrive at the respective percent of AUM in each bucket. The Morningstar percentile ranking is based on the fund’s total-return percentile rank relative to all funds that have the same category for the same time period. The highest (or most favorable) percentile rank is 1%, and the lowest (or least favorable) percentile rank is 100%. Morningstar total-return includes both income and capital gains or losses and is not adjusted for sales charges. The top-performing funds in a category will always receive a rank of 1. For the 1-, 3-, 5- and 10-year periods ending June 30, 2013, 51%, 55%, 64% and 83% of the 51, 40, 39 and 30 Complex-Wide mutual funds; 50%, 44%, 58% and 83% of the 40, 32, 31 and 24 Fundamental Equity mutual funds; and 33%, 100%, 100% and 100% of the 6,4,4 and 4 Fixed Income mutual funds outperformed the majority of their Morningstar peers based on total returns. On an asset-weighted basis, 85% of the Complex-Wide mutual fund assets, 82% of the Fundamental Equity mutual fund assets and 100% of the Fixed Income mutual fund assets outperformed the majority of their Morningstar peers based on total returns for the 10-year period. The Overall Morningstar RatingTM for a fund is derived from a weighted-average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar RatingTM metrics. For each fund with at least a three-year history, Morningstar calculates a Morningstar RatingTM 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 variations in the distribution percentages.) The Morningstar RatingTM may differ among share classes of a mutual fund as a result of different sales loads and/or expense structures. It may be based, in part, on the performance of a predecessor fund. Morningstar does not rate funds with less than a 3-year performance history. For the period ending June 30, 2013, 43%, 44% and 67% of Complex-Wide mutual funds had a 4- or 5-star Morningstar rating for the 3-, 5- and 10-year periods based on risk-adjusted returns for 40, 39 and 30 funds, respectively. 40 funds were included in the analysis for the Overall period. Investing involves risk, including the possible loss of principal. The value of your investment will fluctuate over time and you may gain or lose money. A fund’s performance may be affected by risks that include those associated with non-diversification, non-investment grade debt securities, high-yield/high-risk securities, undervalued or overlooked companies, investments in specific industries or countries and potential conflicts of interest. Additional risks to funds may include those associated with investing in foreign securities, emerging markets, initial public offerings, real estate investment trusts (REITs), derivatives, short sales, commodity linked Investments and companies with relatively small market capitalizations. Each fund has different risks, please see a Janus prospectus for more information about risks, fund holdings and other details.
