Forward-looking statements This communication contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements may include: management plans relating to the Transaction; the expected timing of the completion of the Transaction; the ability to complete the Transaction; the ability to obtain any required regulatory, shareholder or other approvals; any statements of the plans and objectives of management for future operations, products or services, including the execution of integration plans relating to the Transaction; any statements of expectation or belief; projections related to certain financial metrics; and any statements of assumptions underlying any of the foregoing. Forward-looking statements are typically identified by words such as “believe,” “expect,” “anticipate,” “intend,” “plan,” “seek,” “target,” “outlook,” “estimate,” “forecast,” “project” and other similar words and expressions, and variations or negatives of these words. Forward-looking statements by their nature address matters that are, to different degrees, subject to numerous assumptions, known and unknown risks and uncertainties, which change over time and are beyond our control. Forward-looking statements speak only as of the date they are made and investors and security holders are cautioned not to place undue reliance on any such forward-looking statements. Janus Capital Group Inc. (“Janus Capital Group”) does not assume any duty and does not undertake to update forward-looking statements, whether as a result of new information, future developments or otherwise, should circumstances change, nor does Janus Capital Group intend to do so, except as otherwise required by securities and other applicable laws. Because forward-looking statements are subject to assumptions and uncertainties, actual results or future events could differ, possibly materially, from those that Janus Capital Group anticipated in its forward-looking statements and future results could differ materially from historical performance. Factors that could cause or contribute to such differences include, but are not limited to, those included under Item 1A “Risk Factors” in Janus Capital Group’s Annual Report on Form 10-K and those disclosed in Janus Capital Group’s other periodic reports filed with the Securities and Exchange Commission (“SEC”), as well as the possibility: that expected benefits of the Transaction may not materialize in the timeframe expected or at all, or may be more costly to achieve; that the Transaction may not be timely completed, if at all; that prior to the completion of the Transaction or thereafter, Janus Capital Group’s businesses may not perform as expected due to transaction-related uncertainty or other factors; that the parties are unable to successfully implement integration strategies related to the Transaction; that required regulatory, shareholder or other approvals are not obtained or other customary closing conditions are not satisfied in a timely manner or at all; reputational risks and the reaction of the companies’ shareholders, customers, employees and other constituents to the Transaction; and diversion of management time on merger-related matters. All subsequent written and oral forward-looking statements concerning the proposed transaction or other matters attributable to Janus Capital Group or any other person acting on their behalf are expressly qualified in their entirety by the cautionary statements referenced above. For any forward-looking statements made in this communication or in any documents, Janus Capital Group claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Annualized, pro forma, projected and estimated numbers are used for illustrative purposes only, are not forecasts and may not reflect actual results.

Reconciliation of non-GAAP financial measures The Company presents adjusted operating income and adjusted net income attributable to JCG as non-GAAP financial measures. Management believes these non-GAAP measures provide greater transparency into our business on an ongoing operations basis and allow more appropriate comparisons with industry peers. Management uses these performance measures to evaluate the business, and they are consistent with internal management reporting. The most directly comparable GAAP measures are operating income and net income attributable to JCG. These non-GAAP measures should not be considered as substitutes for any measures derived in accordance with GAAP and may not be comparable to other similarly titled measures of other companies. Additional reconciling items may be added in the future to these non-GAAP measures if deemed appropriate. The tax effect related to reconciling items has been calculated based on the tax rate attributable to the jurisdiction to which the transaction relates.

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.

Mathematical equity performance disclosure For the period ending December 31, 2016, 0%, 40%, 33% and 33% 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. Core Fund – Class T (2/03); INTECH U.S. Managed Volatility Fund – Class I (12/05); INTECH International Managed Volatility Fund – Class I (5/07), INTECH Global Income Managed Volatility Fund – Class I (12/11), Janus Aspen INTECH U.S. Low Volatility Portfolio – Service Shares (9/12) and INTECH Emerging Markets Managed Volatility Fund – Class I (12/14). INTECH's focus on managed volatility may keep the Fund from achieving excess returns over its index. The strategy may underperform during certain periods of up markets and may not achieve the desired level of protection in down markets. 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. 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. These risks are magnified in emerging markets. 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 presented reflect the deduction of model investment advisory fees, and not the advisory fees actually charged to the accounts in the composite. Prior to December 31, 2004, the model advisory fees deducted reflect the maximum fixed fee in effect for each strategy. Beginning January 1, 2005, the model advisory fees deducted reflect the standard fee schedule in effect during the period shown, applied to each account in the composite on a monthly basis. Standard fee schedules are available upon request. Actual advisory fees paid may vary among clients invested in the same strategy, which may be higher or lower than the model advisory fees. Some accounts 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. 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 generally 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 typically valued as of the close of their respective local markets. However, if a significant event takes place between the close of the local market and the close of the U.S. domestic market, a security may be fair valued. Non-U.S. securities are translated into U.S. dollars using the 4:00 P.M. London spot rate. 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 those strategies with at least a 1-year track record. Absolute-risk strategies are excluded. MSCI makes no express or implied warranties or representations and shall have no liability whatsoever with respect to any MSCI data contained herein. The MSCI data may not be further redistributed or used as a basis for other indices or any securities or financial products This report has not been approved, reviewed or produced by MSCI.

(“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 relative return, discretionary managed accounts (not mutual funds) that are advised or sub-advised by INTECH. “Janus Equity Funds” means all fundamental equity funds managed by Janus, including asset allocation funds; Perkins and INTECH funds are excluded. “Perkins Mutual Funds” means all fundamental equity funds managed by Perkins, including Perkins asset allocation funds; Janus-managed and INTECH funds are excluded. Mutual fund relative performance analysis shown is for each Fund's parent share class (typically the share class with the longest performance history): 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 December 31, 2016, 36%, 68%, 64% and 72% of the 55, 50, 47 and 36 Complex-Wide mutual funds; 38%, 74%, 62% and 73% of the 40, 39, 37 and 30 Fundamental Equity mutual funds; 33%, 33%, 67% and 100% of the 9, 6, 6 and 4 Fixed Income mutual funds outperformed the majority of their Morningstar peers based on total returns. For the 1-, 3-, 5- and 10-year periods ending December 31, 2016, 31%, 74%, 73% and 69% of the 32, 31, 30 and 26 Janus Equity mutual funds; 63%, 75%, 14% and 100% of the 8, 8, 7 and 4 Perkins mutual funds outperformed the majority of their Morningstar peers based on total returns. On an asset-weighted basis, 80% of the Complex-Wide mutual fund assets, 77% 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. On an asset-weighted basis, 79% and 75% of the Janus Equity mutual fund assets; and 1% and 100% of the Perkins mutual fund assets outperformed the majority of their Morningstar peers based on total returns for the 5- and 10-year periods. 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 December 31, 2016, 38%, 51% and 58% 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 50, 47 and 36 funds, respectively. 50 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.
