PART I

FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. In addition, Janus Capital Group Inc. (collectively "Janus" or the "Company") may make other written and oral communications from time to time (including, without limitation, in the Company's 2007 Annual Report to Stockholders) that contain such statements. Forward-looking statements include statements as to industry trends and future expectations of the Company and other matters that do not relate strictly to historical facts and are based on certain assumptions by management. These statements are often identified by the use of words such as "may," "will," "expect," "believe," "anticipate," "intend," "could," "should," "estimate" or "continue," and similar expressions or variations. These statements are based on the beliefs and assumptions of Company management based on information currently available to management. Such forward-looking statements are subject to risks, uncertainties and other factors that could cause actual results to differ materially from future results expressed or implied by such forward-looking statements. Important factors that could cause actual results to differ materially from the forward-looking statements include, among others, the risks described in Part I, Item 1A, Risk Factors, and elsewhere in this report and other documents filed or furnished by Janus from time to time with the Securities and Exchange Commission. Janus cautions readers to carefully consider such factors. Furthermore, such forward-looking statements speak only as of the date on which such statements are made. Janus undertakes no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements.

ITEM 1.    BUSINESS

Janus Capital Group Inc. (collectively, "Janus" or the "Company") provides investment management and administrative services to mutual funds, separate accounts and institutional clients in both domestic and international markets. Janus provides investment advisory services through its primary subsidiaries, Janus Capital Management LLC ("JCM" or "Janus ex-INTECH") and Enhanced Investment Technologies, LLC ("INTECH").

Revenues are generally based upon a percentage of the market value of assets under management and are calculated as a percentage of the daily average asset balance in accordance with contractual agreements with the Company's mutual funds, separate accounts and subadvised relationships (collectively referred to herein as "products" or "investment products"). Certain investment products are also subject to performance fees which vary based on their relative performance as compared to a benchmark index and the level of assets subject to such fees. Assets under management primarily consist of domestic and international equity and debt securities. Accordingly, fluctuations in the financial markets, relative investment performance, sales and redemptions of investment products, and changes in the composition of assets under management are all factors that have a direct effect on Janus' operating results.

Janus Capital Management

Janus considers itself a leader in equity investing, beginning with the launch of the Janus Fund more than 35 years ago. Janus' investment teams are led by its co-Chief Investment Officers, who are charged with driving investment performance across all disciplines and subsidiaries while maintaining a structured investment approach. Janus' investment teams seek to identify strong businesses with sustainable competitive advantages or improving returns on capital that sell at a discount to what the teams believe they are worth. Janus believes its depth of research, its experienced portfolio managers and analysts, its willingness to make concentrated investments when Janus believes it has a research edge, and its commitment to delivering strong, long-term results for its investors are what differentiate Janus from its competitors.

2

---

For the one- and three-year periods ended December 31, 2007, approximately 89% and 86%, respectively, of the Company's largest fund family, Janus Investment Fund ("JIF"), were ranked in the top two Lipper Analytics quartiles based upon total returns. On a five-year total return basis, 76% of JIF funds were in the top two Lipper quartiles at December 31, 2007. (See Exhibit 99.1 for complete Lipper rankings.)

INTECH

INTECH's unique investment process is based on a mathematical theorem that attempts to capitalize on the volatility in stock price movements. The goal is to achieve long-term returns that outperform the benchmark index while controlling risks and trading costs. Acquired by Janus in 2002, INTECH has managed institutional portfolios since 1987, establishing one of the industry's longest continuous performance records of mathematically driven equity investing strategies. INTECH assets under management have grown from approximately $6.0 billion when Janus acquired it in 2002 to $69.7 billion at the end of 2007. Risk-managed products have primarily been sold through the institutional channel, which generally has lower management fees than products sold through the intermediary, international or retail channels.

Since inception, twelve out of thirteen INTECH investment strategies as of December 31, 2007, have outperformed their respective benchmarks, net of fees and on a gross fee basis. Additionally, all of INTECH's investment strategies rank in the top 2 quartiles of their corresponding universes for alpha and information ratio, from inception through December 31, 2007, based on Callan Risk-Return Rankings that provide industry measurements of risk and reward.

Distribution Channels

Janus' sales organization capabilities are segmented into four distribution channels: retail, U.S. intermediary, U.S. institutional and international.

Retail Channel

The retail channel serves individual investors who access Janus directly or through supermarket platforms. These investors are served through Janus' largest fund family, JIF. Assets in the retail channel totaled $59.5 billion, or 29% of total assets under management at December 31, 2007.

U.S. Intermediary Channel

The U.S. intermediary channel serves financial intermediaries and retirement plans for the advice-driven market, which includes asset managers, bank/trust officers, broker-dealers, independent planners, third-party administrators and insurance companies. Janus has aligned the channel to focus resources on distributor needs and is targeting product platforms that tend to have high asset retention rates in order to enhance long-term returns and margins. Janus has made significant investments in the U.S. intermediary channel by increasing the number of wholesalers from 23 at the beginning of 2005 to 50 at the end of 2007. Assets in the domestic intermediary channel totaled $60.1 billion, or 29% of total assets under management at December 31, 2007.

U.S. Institutional Channel

The U.S. institutional channel serves endowments, foundations, municipalities, corporations and Taft-Hartley clients and focuses on distribution through consulting relationships and on a direct basis. The current asset base in this channel is weighted heavily toward INTECH's risk-managed products. Assets in the U.S. institutional channel totaled $73.7 billion, or 35% of total assets under management at December 31, 2007.

3

---

International Channel

The international channel serves all products sold outside of the United States and includes international retail, intermediary and institutional accounts. International products are offered through Janus Capital Funds Plc, Janus Selection Funds, separate accounts and subadvisory relationships. Assets in the international channel totaled $13.4 billion, or 7% of total assets under management at December 31, 2007.

COMPETITION

The investment management industry is relatively mature and saturated with competitors that provide services similar to Janus. As such, Janus encounters significant competition in all areas of its business. Janus competes with other investment managers, mutual fund advisers, brokerage and investment banking firms, insurance companies, hedge funds, venture capitalists, banks and other financial institutions, many of which are larger, have proprietary access to distribution, have a broader range of product choices and investment capabilities, and have greater capital resources. Janus believes its ability to successfully compete in this market is based on its ability to: achieve consistently strong investment performance; maintain and build upon its distribution relationships and continue to create new ones; develop appropriately priced investment products well suited for its distribution channels and attractive to underlying clients and investors; offer multiple investment choices; provide effective shareowner servicing; retain and strengthen the confidence of its clients; attract and retain talented portfolio management and sales personnel; and develop and leverage its brand in existing and new distribution channels. Additionally, Janus' ability to successfully compete with other investment management companies is highly dependent on its reputation and its relationship with clients.

Competition in the investment management industry continues to increase as a result of greater flexibility afforded to banks and other financial institutions to sponsor and distribute mutual funds. Furthermore, the marketplace for investment products is rapidly changing; investors are becoming more sophisticated; the demand for and access to investment advice and information are becoming more widespread; and more investors are demanding investment vehicles that are customized to their personal requirements.

REGULATION

The investment management industry is subject to extensive federal, state and international laws and regulations intended to benefit or protect the shareholders of funds managed by Janus and advisory clients of Janus. The costs of complying with such laws and regulations have significantly increased and may continue to contribute significantly to the costs of doing business as an investment adviser. These laws and regulations generally grant supervisory agencies broad administrative powers, including the power to limit or restrict the conduct of Janus' business and to impose sanctions for failure to comply with the laws and regulations. Possible consequences or sanctions for such failure to comply include, but are not limited to, voiding of investment advisory and subadvisory agreements; the suspension of individual employees (particularly investment management and sales personnel); limitations on engaging in certain lines of business for specified periods of time; revocation of registrations; disgorgement of profits; and censures and fines. Further, such laws and regulations may provide the basis for litigation that may also result in significant costs and reputational harm to Janus.

The Investment Advisers Act

The Securities and Exchange Commission ("SEC") is the federal agency generally responsible for administering the federal securities laws. Certain subsidiaries of Janus are registered investment advisers under the Investment Advisers Act of 1940, as amended (the "Investment Advisers Act") and, as such, are supervised by the SEC. The Investment Advisers Act requires registered investment

4

---

advisers to comply with numerous and pervasive obligations, including among other things, record-keeping requirements, operational procedures, registration and reporting and disclosure obligations. Certain subsidiaries of Janus are also registered with regulatory authorities in various states, and thus are subject to the oversight and regulation of such states' regulatory agencies.

The 1940 Act

Through its subsidiaries, Janus acts as adviser or subadviser to both proprietary and non-proprietary mutual funds, which are registered with the SEC pursuant to the Investment Company Act of 1940, as amended (the "1940 Act"). Janus subsidiaries also serve as adviser or subadviser to separately managed accounts and commingled accounts that are not required to register under the 1940 Act. As an adviser or subadviser to a registered investment company, Janus must comply with the requirements of the 1940 Act and related regulations including among other things, requirements relating to operations, fees charged, sales, accounting, recordkeeping, disclosure and governance. In addition, the adviser or subadviser to a registered investment company generally has obligations with respect to the qualification of the registered investment company under the Internal Revenue Code of 1986, as amended (the "Code").

Broker-Dealer Regulations

Janus' limited purpose broker-dealer subsidiary, Janus Distributors LLC ("JD"), is registered with the SEC under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and is a member of the Financial Industry Regulatory Authority ("FINRA"), the securities industry's self-regulatory organization. JD is the general distributor and agent of the sale and distribution of shares of certain mutual funds that are directly advised or serviced by JCM. The SEC imposes various requirements on Janus' limited broker-dealer operations including disclosure, recordkeeping and accounting. FINRA has established conduct rules for all securities transactions among broker-dealers and private investors, trading rules for the over-the-counter markets and operational rules for its member firms. The SEC and FINRA also impose net capital requirements on registered broker-dealers.

Janus' limited broker-dealer is also subject to regulation under state law. The federal securities laws prohibit states from imposing substantive requirements on broker-dealers that exceed those under federal law. This does not preclude the states from imposing registration requirements on broker-dealers that operate within their jurisdiction or from sanctioning these broker-dealers and their employees for engaging in misconduct.

ERISA

Certain Janus subsidiaries are also subject to the Employee Retirement Income Security Act of 1974, as amended ("ERISA") and related regulations to the extent they are considered "fiduciaries" under ERISA with respect to some of their clients. ERISA, related provisions of the Code and regulations issued by the Department of Labor impose duties on persons who are fiduciaries under ERISA and prohibit some transactions involving the assets of each ERISA plan that is a client of a Janus subsidiary as well as some transactions by the fiduciaries (and several other related parties) to such plans.

International Regulations

Certain Janus subsidiaries are authorized to conduct investment business in international markets and are subject to foreign regulation. Janus' international subsidiaries are subject to the regulatory supervision and requirements of various agencies, including the Financial Services Authority in the United Kingdom, the Irish Financial Services Regulatory Authority, the Securities and Futures Commission of Hong Kong, the Monetary Authority of Singapore, the Financial Services Agency of Japan and Canadian Securities Commissions. These regulatory agencies have broad supervisory and

5

---

disciplinary powers, including, among others, the power to temporarily or permanently revoke the authorization to carry on regulated business, the suspension of registered employees, censures and fines for both regulated businesses and their registered employees.

Many of the non-U.S. securities exchanges and regulatory authorities have imposed rules (and others may impose rules) relating to capital requirements applicable to Janus' foreign subsidiaries. These rules, which specify minimum capital requirements, are designed to measure general financial integrity and liquidity, and require that a minimum amount of assets be kept in relatively liquid form.

EMPLOYEES

As of December 31, 2007, Janus had 1,213 full-time employees related to continuing operations and 429 full-time employees related to discontinued operations. No Janus employees are represented by a labor union.

ADDITIONAL FINANCIAL INFORMATION

See additional financial information on segments and geographical areas in Part II, Item 8, Financial Statements and Supplementary Data, Note 19 — Segment and Geographic Information, of this Form 10-K.

ITEM 1A.    RISK FACTORS

Janus' revenues and profits are dependent on the value, composition and relative investment performance of its investment products.

Any decrease in the value or amount of assets under management will cause a decline in revenues and operating results. Assets under management may decline for various reasons, many of which are not under Janus' control.

6

---

Factors that could cause assets under management and revenues to decline include the following:

•

Declines in equity markets.  Janus' assets under management are concentrated in the U.S. equity markets and, to a lesser extent, in the international equity markets. As such, declines in the equity markets or the market segments in which Janus' investment products are concentrated will cause assets under management to decrease.

•

Declines in fixed income markets.  In the case of fixed income investment products, which invest in high-quality short-term instruments, as well as other fixed income securities, the value of the assets may decline as a result of changes in interest rates, available liquidity in the markets in which a security trades, an issuer's actual or perceived creditworthiness or an issuer's ability to meet its obligations.

•

Redemptions and other withdrawals.  Investors (in response to adverse market conditions, inconsistent investment performance, the pursuit of other investment opportunities, or otherwise) may reduce their investments in specific Janus investment products or in the market segments in which Janus' investment products are concentrated.

•

Political and general economic risks.  The investment products managed by Janus may invest significant funds in international markets that are subject to risk of loss from political or diplomatic developments, government policies, civil unrest, currency fluctuations and changes in legislation related to foreign ownership. International markets, particularly emerging markets, are often smaller, may not have the liquidity of established markets, may lack established regulations and may experience significantly more volatility than established markets.

•

Relative investment performance.  Janus' investment products are often judged on their performance as compared to benchmark indices, peer groups or on an absolute return basis. Any period of prolonged underperformance of investment products may result in the loss of existing assets and impact Janus' ability to attract new assets. In addition, approximately 16% of the Company's assets under management at December 31, 2007, are subject to performance fees. Performance fees are based on each product's investment performance as compared to an established benchmark index over a specified period of time. If investment products subject to performance fees underperform their respective benchmark index for a prolonged period, Janus' results of operations may be adversely impacted.

Janus' results are dependent on its ability to attract and retain key personnel.

The investment management business is highly dependent on the ability to attract, retain and motivate highly skilled, and often highly specialized, technical, executive, sales and investment management personnel. The market for investment and sales professionals is extremely competitive and is increasingly characterized by the frequent movement of portfolio managers, analysts and salespersons among different firms. Any cost-reduction initiative, changes to management structure, shifts in corporate culture, changes to corporate governance authority, or adjustments or reductions to compensation have and could continue to result in legal claims and could impact Janus' ability to retain key personnel. If Janus is unable to retain key personnel, it could have an adverse effect on Janus' results of operations and financial condition. Additionally, portfolio managers and salespersons often maintain relationships with their clients. As such, the departure of a portfolio manager or salesperson may cause the loss of clients, which could have an adverse effect on Janus' results of operations and financial condition.

Janus is dependent upon third-party distribution channels to access clients and potential clients.

Janus' ability to market and distribute its investment products is significantly dependent on access to the client base of insurance companies, defined contribution plan administrators, securities firms,

7

---

broker-dealers, banks and other distribution channels. These companies generally offer their clients various investment products in addition to, and in competition with, Janus. Further, the private account business uses referrals from financial planners, investment advisers and other professionals. Janus cannot be certain that it will continue to have access to these third-party distribution channels or have an opportunity to offer some or all of its investment products through these channels. The inability to access clients through third-party distribution channels could have a material adverse effect on Janus' ability to maintain or increase assets under management, its financial condition, results of operations or business prospects.

INTECH's investment process is highly dependent on key employees and proprietary software.

Over the last several years, INTECH has become a more significant part of Janus' investment management business, representing 34% of total assets under management as of December 31, 2007, and 21% of total revenue for the year ended December 31, 2007. INTECH's investment process is based on complex and proprietary mathematical models, which seek to outperform various indices by capitalizing on the volatility in stock price movements while controlling trading costs and overall risk relative to the index. The maintenance of such models for current products and the development of new products are highly dependent on certain key INTECH employees. If INTECH is unable to retain key personnel or if the mathematical investment strategies fail to produce the intended results, INTECH may not be able to maintain the historical level of strong investment performance and clients may redeem assets, which could have an adverse effect on Janus' results of operations and financial condition.

The regulatory environment in which Janus operates has changed and may continue to change.

Janus may be adversely affected as a result of new or revised legislation or regulations or by changes in the interpretation or enforcement of existing laws and regulations. Compliance with these and other new reporting and operational requirements and regulations has increased significantly and may continue to increase the cost of operating mutual funds and related investment products, which could have an adverse effect on Janus' results of operations and financial condition. (See Item 1, Business — Regulation).

Janus is named as a defendant in class action lawsuits and other litigation.

Janus, certain of the Janus funds, and certain (past and present) officers of Janus are named as defendants in class action lawsuits and other litigation (See Item 8, Note 16). These lawsuits seek unspecified compensatory and punitive damages. Janus is unable to estimate the range of potential losses that would be incurred if the plaintiffs in any of these actions were to prevail, or to determine the total potential effect that they may have on Janus' results of operations, financial position and cash flows. Any settlement or judgment on the merits of these actions could have a material adverse effect on Janus' liquidity, results of operations and financial condition.

Janus' business is vulnerable to failures in support systems and customer service functions.

The ability to consistently and reliably obtain securities pricing information, process shareowner transactions and provide reports and other customer service to the shareowners of funds and other investment products managed by Janus is essential to Janus' operations. Any delays or inaccuracies in obtaining pricing information, Janus' ability to price illiquid or thinly traded securities without readily obtainable market quotes, processing shareowner transactions or providing reports, and any inadequacies in other customer service could alienate customers and potentially give rise to claims against Janus. Janus' customer service capabilities as well as Janus' ability to obtain prompt and accurate securities pricing information and to process shareowner transactions and reports, are dependent on communication and information systems and services provided by third-party vendors.

8

---

Although Janus has established disaster recovery plans, these systems could suffer failures or interruptions due to various natural or man-made causes, and the backup procedures and capabilities may not be adequate to avoid extended interruptions. Additionally, Janus places significant reliance on its automated customer service systems, thereby increasing the related risks if such systems were to fail. A failure of these systems could have an adverse effect on Janus' results of operations and financial condition.

Janus' business is dependent on investment advisory agreements that are subject to termination, non-renewal or reductions in fees.

Janus derives revenue and net income from investment advisory agreements with mutual funds and other investment products. The termination of, or failure to renew, one or more of these agreements or the reduction of the fee rates applicable to such agreements could have a material adverse effect on revenues and profits. With respect to investment advisory agreements with mutual funds, these agreements may be terminated by either party with notice, or terminated in the event of an "assignment" (as defined in the 1940 Act), and must be approved and renewed annually by the independent members of each fund's board of directors or trustees, or its shareowners, as required by law. In addition, the board of directors or trustees of certain funds and separate accounts generally may terminate these investment advisory agreements upon written notice for any reason and without penalty.

Janus' substantial indebtedness could adversely affect its financial condition and results of operations.

Janus has a significant amount of indebtedness which could limit its ability to obtain additional financing for working capital, capital expenditures, stock repurchases, acquisitions, debt service requirements or other purposes. It may also increase Janus' vulnerability to adverse economic, market and industry conditions, limit Janus' flexibility in planning for, or reacting to, changes in business operations or to the asset management industry overall, and place Janus at a disadvantage in relation to competitors that have lower debt levels. Any or all of the above events and/or factors could have an adverse effect on results of operations and financial condition.

Janus may incur losses as a result of providing support to money market funds advised by the Company.

Janus' money market funds (the "Funds") attempt to provide current income and limit exposure to losses by investing in high-quality, investment grade securities with short-term durations. Adverse events or circumstances related to individual securities or the market in which the securities trade may cause other-than-temporary declines in value. In these situations, Janus may elect to support its Funds in a variety of means, including but not limited to, purchasing securities held by the Funds, reimbursing for any losses incurred or providing a letter of credit. Janus is not contractually or legally obligated to support the Funds. Janus has, however, provided financial support in the past and may do so in the future. Any future support may have an adverse effect on results of operations and financial condition.

ITEM 5.    MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Janus Common Stock

Janus' common stock is traded on the New York Stock Exchange ("NYSE") (symbol: JNS). The following table sets forth the high and low sale prices as reported on the NYSE composite tape for each completed quarter since January 1, 2006.

The following graph illustrates the cumulative total shareholder return (rounded to the nearest whole dollar) of Janus' common stock over the five year period ending December 31, 2007, the last trading day of 2007, and compares it to the cumulative total return on the Standard & Poor's ("S&P") 500 Index and the S&P Diversified Financials Index. The comparison assumes a $100 investment on December 31, 2002, in Janus' common stock and in each of the foregoing indices and assumes reinvestment of dividends, if any. This table is not intended to forecast future performance of Janus' common stock.

On December 31, 2007, there were approximately 3,876 holders of record of Janus' outstanding common stock.

Janus declared an annual $0.04 per share dividend in the second quarter of 2007, 2006 and 2005, and anticipates paying a dividend in 2008. The payment of cash dividends is within the discretion of Janus' Board of Directors and will depend on many other factors, including, but not limited to, Janus' results

On January 23, 2007, Janus' Board of Directors authorized the repurchase of up to an additional $500 million of Janus common stock with no expiration date, to take effect when the prior authorization was utilized, which occurred on February 27, 2007. On July 24, 2007, Janus' Board of Directors authorized another $500 million stock repurchase program to take effect when the January authorization was fully utilized, which occurred on August 15, 2007. During 2007, Janus repurchased 31,538,899 shares at an aggregate cost of $828.6 million under the current and previous authorizations. The Company cautions that there are no assurances that any future repurchases will actually occur.

In addition to this program, for the year ended December 31, 2007, Janus repurchased 759,081 shares from employees as part of a share withholding program (established under Rule 10b5-1 of the Securities Exchange Act of 1934) to satisfy employees' income tax liabilities attributable to the vesting of restricted stock awards, and 8,744 shares were surrendered to Janus related to the exercise of stock options.

(1)

Revenues generally vary with average assets under management. However, in the years presented, revenues have also been impacted by the Mutual Fund Investigation settlement announced in 2004 and performance fees. As part of the Mutual Fund Investigation settlement, Janus reduced management fees on most of its mutual funds effective July 1, 2004; these fees can only be increased with the approval of the independent fund trustees and shareowners. The fee reduction totaled $11.7 million in the second

---

half of 2004. The acquisition of INTECH in 2002 added performance fees, which vary with relative investment performance and the amount of assets subject to such fees. Beginning in 2007, certain mutual funds became subject to performance fees. Janus earned $11.2 million of performance fees from mutual funds during 2007.

(2)

Operating expenses include impairments, restructuring and Mutual Fund Investigation charges and recoveries. Impairment charges are related to terminated investment management relationships with assigned intangible values. Restructuring charges are related to severance and facility closures. Restructuring charges totaled $11.0 million, $5.5 million, $26.6 million and $11.9 million in 2006, 2005, 2004 and 2003, respectively. Mutual Fund Investigation charges represent legal fees and settlement costs, net of insurance recoveries for such expenses, directly related to the Mutual Fund Investigation. Mutual Fund Investigation charges, net of recoveries, totaled $(14.1) million, $(9.3) million, $65.0 million and $71.8 million in 2006, 2005, 2004 and 2003, respectively.

(3)

Through 2003, Janus utilized soft dollars to acquire access to third-party investment research databases and reports. Soft dollars are arrangements under which research products and services are obtained by an investment adviser from or through a broker-dealer in exchange for the direction by the adviser of client brokerage transactions to the broker-dealer. For 2004 through 2006, such products and services were paid for by Janus and reflected as operating expenses. In accordance with SEC guidance released in 2006 and based upon discussions with the independent fund trustees, Janus began utilizing soft dollars again in 2007. Soft dollars did not have a material impact on 2007 operating results.

(4)

Interest expense for 2004 declined from 2003 as a result of a debt restructuring and the repayment of debt. As part of the debt restructuring, Janus incurred a non-operating debt extinguishment charge of $55.5 million primarily related to the premium paid to exchange certain notes with high interest rates for new notes with lower interest rates. Interest expense for 2007 increased as a result of issuing additional debt.

(5)

During 2007, Janus classified certain investment securities as trading. Unrealized gains, net of losses, of $17.6 million associated with trading securities are recorded in earnings. In addition, Janus recognized an $18.2 million impairment charge associated with structured investment vehicle ("SIV") securities acquired from money market funds advised by Janus.

(6)

In December 2003, Janus exchanged 32.3 million common shares of DST Systems, Inc. ("DST") for 100% of the stock of Capital Group Partners, Inc., a corporation that included a printing and graphics design business with a value of $115.0 million and $999.3 million in cash, in a tax-free transaction that resulted in a $631.3 million gain and the reversal of $176.4 million of associated deferred tax expense. Prior to this transaction, DST was accounted for as an equity method investment. In 2004, Janus sold its remaining DST common shares for a gain of $228.0 million in a taxable transaction.

(7)

During the third quarter 2007, Janus initiated a plan to dispose of Rapid Solutions Group ("RSG"), previously reported as the Printing and Fulfillment segment. Prior periods have been reclassified to separately present the results of continuing and discontinued operations. The results of discontinued operations for 2007 include impairment charges totaling $67.1 million (net of a $6.2 million tax benefit) to write-down the carrying value of RSG to estimated fair market value less costs to sell. Discontinued operations for 2003 includes Nelson Managers Plc, which was sold on October 23, 2003.

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

EXECUTIVE SUMMARY

Janus finished 2007 with assets under management of $206.7 billion, an increase of 23% from the end of 2006.

Long-term net flows for 2007 totaled $9.8 billion compared to $2.3 billion for 2006.

Janus ex-INTECH long-term net flows improved significantly to $7.5 billion of inflows compared with outflows of $9.7 billion in 2006, representing the first annual period of positive long-term net flows in six years.

Janus' investment product performance remained strong in 2007. As of December 31, 2007, 89%, 86% and 76% of the JIF funds were in the top half of their Lipper categories on a one-, three- and five-year total return basis, respectively.

Operating margins were 31.3% in 2007 compared with 25.5% in 2006 and diluted earnings per share from continuing operations increased 57%.

During 2007, Janus initiated a new advertising campaign that focuses on the promotion and awareness of the Janus brand.

In 2007, Janus bought 32.3 million shares of its common stock at an aggregate cost of $845.6 million, reducing outstanding common shares by 14.1%.

INVESTMENT MANAGEMENT OPERATIONS (CONTINUING OPERATIONS)

Assets Under Management and Flows

The following table presents the components of Janus' assets under management (in billions):

*

Excludes money market flows. Sales and redemptions are presented net on a separate line due to the short-term nature of the investments.

15

---

Janus' average assets under management totaled $190.4 billion during 2007, an increase of $33.7 billion from 2006 and $55.2 billion from 2005. The increases were driven by positive market/fund performance and positive long-term net flows.

Janus ex-INTECH's 2007 long-term net flows improved by $17.2 billion over 2006 and $21.6 billion over 2005 from significant increases in sales. Sales efforts have been facilitated by strong relative investment performance, increased penetration in the intermediary channel from expansion initiatives over the last three years, and a shift in investor preference from value to growth investing (as growth indices generally outperformed value indices in 2007).

Janus ex-INTECH's investment performance remained strong despite the loss of several portfolio managers during 2007. Janus manages change through the development of investment analysts and the cultivation of the next generation of portfolio managers. The recent departures have not resulted in significant client losses.

INTECH's net long-term inflows declined to $2.3 billion in 2007 compared to $12.0 billion in 2006 and $16.1 billion in 2005 primarily as a result of increased redemptions. Redemptions increased as a result of the relative underperformance of certain key investment strategies through most of 2007 and 2006 and several clients rebalancing their portfolios. Despite the recent relative underperformance, INTECH's long-term performance remains strong, with 89%, 100% and 100% of all product strategies with at least a 3-, 5- and 10-year performance track record, respectively, outperforming their respective benchmarks during each of those periods ended December 31, 2007.

Revenues

Revenues are generally based upon a percentage of the market value of assets under management and are calculated as a percentage of the daily average asset balance in accordance with contractual agreements with the Company's investment advisory clients. Certain INTECH private accounts (and beginning in 2007, certain mutual funds) are subject to performance fees which vary based on the amount of assets subject to such fees and the relative performance of each account. Assets under management primarily consist of domestic and international equity and debt securities. Accordingly, fluctuations in the financial markets, relative investment performance, sales and redemptions of investment products, and changes in the composition of assets under management are all factors that

16

---

have a direct effect on Janus' operating results. The following graph depicts the direct relationship between average assets under management and investment management revenues:

2007 Compared to 2006

Investment management fees increased $147.7 million, or 19.7%, from a similar increase in average assets under management driven primarily by market appreciation and investment performance combined with positive long-term net inflows.

Performance fees have historically been earned on certain INTECH private accounts. Beginning in the first quarter 2007, certain mutual funds also became subject to performance fees. The increase in performance fee revenue was primarily due to fees of $11.2 million earned on mutual funds, partially offset by a decrease of $6.5 million of fees on INTECH private accounts as a result of recent relative underperformance.

Shareowner servicing fees and other revenue improved $28.9 million, or 16.9%, over the comparable prior period primarily as a result of an increase in transfer agent fees which are based on average JIF assets under management, excluding money market assets. Average JIF assets, excluding money market assets, increased 15.6% over the prior year.

Employee compensation and benefits increased $45.5 million, or 14.4%, principally due to higher base salaries, investment team compensation and sales commissions. Base salaries increased $11.5 million from annual merit increases and an 8.3% growth in the average number of employees. The investment team compensation plan implemented in the first quarter 2007 is linked to individual performance, but also ties the aggregate level of compensation to investment management fee revenue. Investment team compensation increased $21.0 million due to higher management fee revenue and relative investment performance. Sales commissions increased $6.6 million due to improved sales, primarily in the intermediary channel.

17

---

Long-term incentive compensation decreased $2.8 million due to the final vesting of a previous grant in the first quarter 2007, partially offset by an increase related to the 2007 annual grant awarded in February, a $17.0 million charge for the contractual acceleration of awards related to certain portfolio managers who resigned in 2007 and accelerated vesting of previous awards based on 2007 financial performance.

Future long-term incentive amortization will be impacted by the 2008 annual grant totaling $71.5 million, which will be recognized ratably over a three-year period and is not subject to performance-based acceleration. In addition, retention grants were awarded to certain Janus investment team members and certain INTECH employees in order to facilitate succession planning and incent key personnel to remain with the Company. The Janus investment team retention grant totaled $21.0 million and will be recognized ratably over a four-year period. The INTECH retention grant totaled $25.0 million and will be recognized ratably over a ten-year period. The retention grants are not subject to performance-based acceleration.

Distribution expenses increased $31.5 million, or 28.6%, from a similar increase in assets under management subject to third-party concessions. Distribution fees are calculated based on a contractual percentage of the market value of assets under management distributed through third-party intermediaries.

Interest expense increased $26.5 million as a result of the issuance of additional debt during 2007. Annual interest expense is expected to increase approximately $36.6 million from the issuance of debt on June 14, 2007, and the debt repayment on June 26, 2007.

Investment gains decreased $7.0 million primarily from the recognition of an $18.2 million impairment charge on SIV securities acquired from money market funds advised by Janus (see discussion in Cash Flows section) and a decrease in realized gains related to the sale of seed capital investments. The impairment charge and decrease in realized gains were partially offset by $17.6 million of income previously recorded as unrealized gains in the equity statement. In the fourth quarter 2007, Janus evaluated its seed capital investments and determined that mutual funds and separate accounts in which it owns a majority interest should be consolidated, with changes in market value reported in current period earnings. As a result, Janus expects that future earnings will be impacted by fluctuations in the market value and amount of consolidated investments.

2006 Compared to 2005

Investment management fees increased $77.1 million, or 11.5%, from a 15.9% increase in average assets under management, partially offset by the impact of the continuing product mix shift toward lower yielding INTECH risk-managed products.

Performance fee revenue decreased $11.9 million, or 44.4%, primarily as a result of INTECH underperformance in 2006 combined with fewer assets subject to a performance-based fee structure.

Shareowner servicing fees and other revenue remained consistent year-over-year as an increase in transfer agent servicing fees was partially offset by a decline in distribution revenue. Transfer agent servicing fees increased 4.9% over the prior year. Distribution revenue is primarily based on average assets in certain share classes of Janus' offshore fund series, which declined 26.9% over the prior year.

Employee compensation and benefits increased $15.7 million as a result of increases in base and incentive compensation for investment and non-investment personnel, partially offset by $10.6 million of lower executive severance charges. Base compensation increased $4.5 million from annual merit increases combined with a 7% increase in the number of employees. Incentive compensation for investment personnel increased $5.4 million primarily from strong investment performance. Incentive compensation for non-investment personnel (sales commissions and firmwide bonuses) increased

18

---

$12.5 million from higher long-term product sales, more distribution personnel and stronger corporate results.

Long-term incentive compensation increased $7.6 million as a result of the annual grant made in February 2006 combined with the accelerated vesting of the 2005 and 2006 awards based on 2006 financial performance, partially offset by the impact of revising the forfeiture estimate. During 2006, Janus revised its estimate for forfeitures as a result of higher than expected employee departures, which resulted in a $5.0 million decrease to long-term incentive compensation in 2006.

Marketing and advertising expenses declined slightly in 2006 as a result of a decrease in advertising expenditures partially offset by mutual fund proxy costs of $4.8 million from proposed fund changes.

Depreciation and amortization decreased primarily as a result an $8.4 million decline in amortization of deferred commissions from lower sales of B shares of the Janus Capital Funds Plc in Europe and Asia, partially offset by an increase in amortization of intangibles related to the February 2006 acquisition of an additional 5% interest in INTECH. The acquisition resulted in the recognition of $32.5 million of intangible assets related to customer contracts and will be amortized over a period of 12 years.

Impairment charges incurred in 2006 represent the loss of certain Janus subadvised relationships. Janus recognizes an impairment charge equal to the unamortized value of the associated intangible asset when formal notification of termination is received.

General, administrative and occupancy expense includes Mutual Fund Investigation recoveries of $14.1 million in 2006, representing insurance recoveries for legal fees incurred as a result of the Mutual Fund Investigation.

DISCONTINUED OPERATIONS

During the third quarter 2007, Janus initiated a plan to dispose of the Printing and Fulfillment operations, represented by RSG, as a result of difficulty in growing the business and Janus' desire to focus on its core investment management business.

RSG provides clients with digital and offset printing and fulfillment services. The digital operation focuses on providing clients with communication solutions using leading-edge print-on-demand technology and software applications that support the process of improving the effectiveness of customer communication through personalization and customization. The offset printing operations provide customers with full-service graphics and design solutions through prepress services and high-speed, high-quality offset printing, including direct marketing packages, brochures, preprinted base stock and collateral pieces.

Results of Discontinued Operations

Production volume and revenue from fulfillment, digital printing and offset printing declined from the prior year as a result of lower nonrecurring or one-time production work in 2007. Operating results for 2007 include impairment charges totaling $67.1 million (net of a $6.2 million tax benefit) to write-down RSG's carrying value to management's estimate of fair value less costs to sell the business. The fair value of RSG at December 31, 2007, was estimated using preliminary bids received from potential buyers.

Although Janus is pursuing the disposal of RSG, a final sale price has not yet been negotiated. A gain or additional loss may be recognized to the extent that the actual sale price varies from management's estimate of fair value less costs to sell. Janus expects to dispose of RSG within the next six months.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

A summary of cash flow data from continuing operations for the years ended December 31 is as follows (in millions):

2007 Cash Flows

Janus' cash flow from operations historically has been positive and sufficient to fund ordinary operations and capital requirements. Fluctuations in operating cash flows are attributable to changes in net income and working capital items, which can vary from period to period based on the timing of cash receipts and payments.

Net cash used for investing activities in 2007 includes $81.0 million for the purchase of an additional 4% interest in INTECH and $108.5 million (including $3.5 million of purchased accrued interest) for the purchase of SIV securities from the Funds, partially offset by $55.2 million of proceeds from the net sale of investments in advised funds.

Cash used for financing activities in 2007 includes $748.4 million of proceeds from the issuance of long-term debt, offset by the repayment of $158.1 million of long-term debt and common stock buybacks of $845.6 million.

2006 Cash Flows

Operating cash flows in 2006 increased $31.1 million to $298.6 million due to changes in net income and working capital items.

Net cash generated from investing activities in 2006 includes proceeds from the maturity and sale of marketable securities, partially offset by a $90.0 million acquisition of an additional 5% interest in INTECH and capital expenditures.

Cash used for financing activities in 2006 consists primarily of common stock repurchases of $516.4 million and the repayment of $113.1 million of long-term debt, partially offset by the issuance of $275.0 million of debt.

2005 Cash Flows

Operating cash flows in 2005 increased from cash used for operations in 2004, which included payments related to the regulatory settlement associated with the Mutual Fund Investigation and income taxes for the sale of DST shares.

Net cash generated from investing activities in 2005 represents proceeds from the maturity and sale of marketable securities, partially offset by capital expenditures.

20

---

Cash used for financing activities in 2005 consists primarily of common stock repurchases of $310.4 million and distributions to the minority owners of INTECH.

Structured Investment Vehicle Securities Acquired by Janus

A SIV is a fund that seeks to generate investment returns through yield curve arbitrage by purchasing high grade medium- and long-term fixed income instruments and funding those purchases by issuing low cost, short-term senior debt instruments such as asset-backed commercial paper and asset-backed medium term notes. In late 2007, widespread illiquidity in the commercial paper and capital markets prevented SIVs from accessing necessary funding for ongoing operations. The securities issued by those SIVs that were unable to access necessary liquidity through banks or other large financial institutions were generally downgraded by rating agencies as a result of expected defaults on maturing securities.

While Janus does not sponsor or serve as asset manager to any SIVs, it does serve as investment adviser to certain money market funds (the "Funds") that have invested in securities issued by SIVs from time to time, including securities issued by Stanfield Victoria Funding LLC ("Stanfield securities"). On December 21, 2007, Moody's Investors Service, Inc. ("Moody's") downgraded the Stanfield securities to a rating below what is generally permitted to be held by a security in the Funds. In connection with this downgrade, Janus purchased all of the Stanfield securities held by the Funds, totaling $108.5 million, to protect investors in the Funds from possible losses associated with such downgrade.

Subsequent to the purchase, Janus undertook a detailed analysis of the assets underlying the Stanfield securities, many of which do not have readily determinable fair values, and estimated a range of fair value by benchmarking those assets against instruments of a similar type with comparable yields, maturities and credit ratings for which fair market values were readily available. As a result of this analysis, Janus recognized an $18.2 million impairment charge (including $3.5 million of purchased accrued interest), reflecting the difference between the estimated fair value and the purchase price of the Stanfield securities.

In January 2008, the Stanfield securities were placed with an enforcement manager to be restructured or sold at the election of each senior note holder. Janus elected to participate in the restructuring of the Stanfield securities. In addition, the collateral agent, Deutsche Bank, filed an interpleader complaint due to conflicting positions of note holders that has effectively prevented the enforcement manager from making any cash payments and other distributions, or from restructuring the Stanfield securities, until the matter is resolved by the New York courts or is settled among the parties. Janus management believes that the anticipated restructuring will likely result in extended maturities and/or a pro-rata distribution of proceeds from the income and principal payments on the assets underlying the Stanfield securities. Given the uncertainty of the restructuring at this time, Janus can not determine the potential impact that a restructuring will have on the value of the Stanfield securities.

Janus may recognize additional impairment charges on the Stanfield securities if the restructuring is unsuccessful or there is an other-than-temporary deterioration in the value of the underlying assets. Janus' total additional risk of loss with respect to the Stanfield securities is limited to the $90.3 million carrying value of its investment.

Structured Investment Vehicle Securities Held by the Funds

In addition to the Stanfield securities purchased by Janus, the Funds held $470 million of securities issued by bank-sponsored SIVs, representing approximately 3.3% of total money market assets under management at the end of February 2008. These SIV securities are scheduled to mature between March and August of 2008. Bank-sponsored SIVs have access to various forms of necessary liquidity through their sponsors or other large financial institutions, and are considered to pose less risk to holders as a result of such liquidity access. However, if the markets relating to investments in SIVs and

21

---

related underlying assets remain illiquid, securities issued by bank-sponsored SIVs could experience declines in market value. Additionally, sponsors could be unable or unwilling to continue their sponsorship of these SIVs, which may cause a decline in the credit quality of the bank-sponsored SIVs. In such circumstances, Janus will analyze the appropriate action on behalf of the Funds, including a potential election by Janus to provide further support to the Funds, which could result in additional impairments and financial losses.

Short-Term Liquidity and Capital Requirements

Janus believes cash from operations should be sufficient to satisfy its short-term capital requirements. Expected short-term uses of cash include ordinary operations, ongoing common stock repurchases, capital expenditures, income tax payments, and interest and principal payments on outstanding debt.

Common Stock Repurchase Program

Janus' Board of Directors has authorized four separate $500 million share repurchase programs beginning in July 2004 with the most recent authorization in July 2007. During 2007 and 2006, the Company repurchased 31.5 million shares for $828.6 million and 24.8 million shares for $492.9 million, respectively, under these authorizations. As of December 31, 2007, $302.2 million is available under the current authorization.

Long-Term Liquidity and Capital Requirements

Expected long-term commitments at December 31, 2007, include the following (in millions):

The information presented above does not include operating related liabilities or capital expenditures that will be committed to in the normal course of business. Janus expects to fund these obligations from cash generated from normal operations.

Interest payments are determined assuming that all debt is held to maturity.

Operating lease obligations are presented net of estimated sublease income of $7.4 million.

Janus has the right to purchase an additional 14% ownership in Perkins, Wolf, McDonnell and Company, LLC ("PWM") each year at a price equal to the fair market value on each respective call date. Janus also may negotiate with the majority owners of PWM to acquire additional interests with terms other than those associated with the annual call rights. The above schedule does not include any estimated payments for the acquisition of additional interests in PWM as Janus is not obligated to acquire any interests and the price is unknown at this time.

Each fiscal year beginning in 2008 and terminating in 2012, each of the two INTECH founding members has the option to require Janus to purchase up to approximately 25% of their current holdings of INTECH shares ("Annual Option Shares") at the fair market value on the date of exercise based on a valuation by an independent investment bank. As of December 31, 2007, each of the two founders owns approximately 6% of INTECH. In the event that either INTECH founder does not fully exercise his annual voluntary sale option in a given year, Janus has the option to require the INTECH founder to sell the remaining balance of the Annual Option Shares at fair market value on the date of exercise.

In addition, each of the founders can require Janus to purchase their INTECH interests if the founder's employment is terminated. The purchase price of the departing founder's INTECH interests will be based on the fair market value on the date of exercise based on a valuation by an independent investment bank. Each founder is entitled to retain approximately one percent of INTECH's shares currently outstanding after employment until his death unless he is terminated for cause or leaves voluntarily while not in good standing. An INTECH founder will be deemed to be in good standing if he voluntarily leaves on or after January 1, 2009, after providing 12 months' prior notice and provided he cooperates with the transition.

The long-term commitments schedule above does not include any estimate for the purchase of the outstanding INTECH interests due to the uncertainty of this obligation and the price at which it may occur. INTECH interests in the aggregate would currently be valued at approximately $223.0 million, based on the most recent fair market value determined by an independent investment bank and agreed upon by INTECH and Janus.

Other Sources of Liquidity

Credit Facility

On June 1, 2007, the Company and the syndicate of banks amended the then existing $200 million Three-Year Competitive Advance and Revolving Credit Facility Agreement (the "Credit Facility"). Under the amended Credit Facility, the bank syndicate's commitment was increased to $350 million, and the maturity date was extended from October 19, 2008, to June 1, 2012. The Credit Facility contains a number of financial covenants including a specified financing leverage ratio and interest coverage ratio. At December 31, 2007, Janus was in compliance with all covenants and there were no borrowings under the Credit Facility.

Shelf Registration

In June 2007, the Company filed a new Shelf Registration Statement ("Shelf Registration") on Form S-3 that registered an indeterminate amount of Janus' common stock, preferred stock and debt securities. This Shelf Registration was effective immediately upon filing under new SEC regulations permitting "well-known seasoned issuers" to register an unlimited amount of securities to be issued. The Shelf Registration replaces the $325.0 million remaining under Janus' previous shelf registration. The issuances of debt in 2007 described below were issued under the Shelf Registration.

Debt

On June 14, 2007, Janus issued $300.0 million of 6.250% Senior Notes due June 15, 2012, and $450.0 million of 6.700% Senior Notes due June 15, 2017 (collectively, the "2007 senior notes"). Interest is paid semiannually on June 15 and December 15 of each year. The proceeds from the 2007 senior note issuances were $748.4 million. On June 26, 2007, approximately $160.0 million of the total proceeds were used to repay the 7.875% Senior Notes due 2032 plus accrued and unpaid interest as of the redemption date. The remaining proceeds may be used for possible future acquisitions, the repurchase of Janus' common stock; and/or general corporate purposes.

If the Company experiences a change of control and the 2007 senior notes are rated below investment grade by Standard & Poor's Rating Service ("S&P") and Moody's, the Company must offer to repurchase all of the 2007 senior notes at a price equal to 101% of the principal amount plus accrued and unpaid interest to the repurchase date.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Janus' consolidated financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods.

Janus continually evaluates the accounting policies and estimates used to prepare the consolidated financial statements. In general, management's estimates are based on historical experience, information from third-party professionals and various other assumptions that are believed to be reasonable under current facts and circumstances. Actual results could differ from those estimates made by management. Janus' critical accounting policies and estimates include income taxes, intangible assets and goodwill, marketable securities and equity compensation.

Accounting for Income Taxes

Significant management judgment is required in developing Janus' provision for income taxes, including the valuation allowances that might be required against deferred tax assets and the evaluation of various income tax contingencies.

Valuation Allowance

Janus has not recorded a valuation allowance on its deferred tax assets as of December 31, 2007, based on management's belief that operating income will more likely than not be sufficient to realize the benefit of the Company's deferred tax assets over time. In the event that actual results differ from these estimates, or if Janus' historical trend of positive operating income changes, Janus may be required to record a valuation allowance on deferred tax assets, which could have a material adverse effect on Janus' consolidated financial condition and results of operations.

Income Tax Contingencies

At December 31, 2007, Janus has an accrued liability of $34.7 million related to tax contingencies for issues raised by various taxing authorities. At any one time, tax returns filed in previous years are subject to audit by various taxing authorities. As a result of these audits and negotiations, additional tax assessments may be proposed or tax contingencies recorded in prior years may be reversed. On January 1, 2007, Janus adopted the provisions of Financial Accounting Standards Board ("FASB") issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" ("FIN 48"), which sets forth a specific recognition threshold and measurement method for the financial statement recognition and measurement of a tax position taken or expected to be taken on a tax return. As a result of the implementation of FIN 48, Janus reduced its tax contingencies liability by $29.3 million. The reduction in the liability and the related change in deferred taxes were accounted for as an increase to retained earnings on January 1, 2007.

Accounting for Intangible Assets and Goodwill

Intangible assets and goodwill comprise $2.5 billion, or 69%, of total assets at December 31, 2007. Goodwill and intangible assets require significant management estimates and judgment, including the valuation and expected life determination in connection with the initial purchase price allocation and the ongoing evaluation for impairment. Janus separately tests goodwill and indefinite-lived intangible assets for impairment annually or more frequently if events or changes in circumstances indicate that the asset may be impaired.

24

---

In connection with the purchase price allocation of acquisitions, Janus will rely on in-house financial expertise or utilize a third-party expert, if considered necessary. Valuations generally rely on management's estimates and judgments as to growth rates and operating margins over a range of possible assumptions for various products, distribution channels and business strategies.

Goodwill represents the excess of cost over the fair value of the identifiable net assets of acquired companies and is not amortized. Goodwill is tested annually for impairment by comparing the fair value of the "reporting unit" associated with the goodwill to the reporting unit's recorded value. If the fair value of the reporting unit is less than its recorded value, it would generally indicate an impairment of goodwill. For purposes of testing goodwill for impairment, Janus has identified one reporting unit.

Indefinite-lived intangible assets primarily represent mutual fund advisory contracts, brand name and trademark. The assignment of indefinite lives to mutual fund advisory contracts, brand name and trademark is based on the assumption that they are expected to generate cash flows indefinitely. This assumption, with respect to mutual fund advisory contracts, is supported by the fact that historically there have not been significant switches between fund managers in the mutual fund industry. Indefinite-lived intangible assets are tested annually for impairment by comparing the fair value of the asset to its carrying value.

Definite-lived intangible assets represent client relationships, which are amortized over their estimated lives of seven to 25 years using the straight-line method. Definite-lived intangible assets are tested only when there are indications of impairment. One component of Janus' definite-lived intangible assets is subadvised contracts. Each subadvised contract has a specific allocation of value and therefore, the loss of an individual contract will cause an impairment charge. Janus recorded impairments of $0.4 million and $11.0 million in 2007 and 2006, respectively, associated with the termination of subadvised contracts. There were no impairments of subadvised contracts in 2005. At December 31, 2007, the net book value of intangible assets related to subadvised contracts was $13.4 million.

To complete the annual tests for potential impairment of intangible assets and goodwill, Janus utilizes a discounted cash flow analysis that requires assumptions regarding projected future earnings and discount rates. In projecting future earnings, Janus considers the following: performance compared to peers; significant changes in the underlying business and products; material and ongoing negative industry or economic trends; and/or other factors that may influence future earnings. Changes in the assumptions underlying the discounted cash flow analysis could materially affect Janus' impairment conclusion. Due to the significance of the identified intangible assets and goodwill to Janus' consolidated balance sheet, any impairment charge could have a material adverse effect on the Company's financial condition and results of operations.

Valuation of Investment Securities

Janus records all investment securities classified as trading or available-for-sale at fair value. Fair value is generally determined using observable market data based on recent trading activity. Where observable market data is unavailable due to a lack of trading activity, Janus utilizes independent third parties or internally developed models to estimate fair value. Estimating fair value requires significant management judgment, including benchmarking to similar instruments with observable market data and applying appropriate discounts that reflect differences between the securities that Janus is valuing and the selected benchmark. Depending on the type of securities owned by Janus, other valuation methodologies may be required. Any variation in the assumptions used to approximate fair value could have a material adverse effect on the Company's financial condition and results of operations.

Janus periodically evaluates the carrying value of investment securities classified as available-for-sale or held-to-maturity for potential impairment. In determining if an impairment exists, Janus considers the duration, extent and circumstances of any decline in fair value. If the decline in value is determined to

25

---

be other than temporary, the carrying value of the security is written down to fair value with the loss recognized currently in earnings.

Equity Compensation

Janus uses the Black-Scholes option pricing model to estimate the fair value of stock options for recording compensation expense. The Black-Scholes model requires management to estimate certain variables, some of which may not be supported by historical activity because of Janus' short history as a publicly traded company. Such estimates include the lives of options from grant date to exercise date, the volatility of the underlying shares and future dividend rates. The two most significant estimates in the Black-Scholes model are volatility and expected life. An increase in the volatility rate increases the value of stock options and a decrease causes a decline in value. Janus estimated expected volatility using an average of Janus' historical volatility and industry and market averages, as appropriate. For expected lives, an increase in the expected life of an option increases its value. Janus factored in employee termination rates combined with vesting periods to determine the average expected life used in the model.

Janus records equity compensation net of estimated forfeitures over the vesting term. Determining the forfeiture estimate requires significant judgment as to the number of actual awards that will ultimately vest over the term of the award. The estimate is reviewed quarterly and any change in actual forfeitures in comparison to estimates may cause an increase or decrease in the ultimate expense recognized in that period and future periods. During the third quarter 2006, the forfeiture estimate was adjusted to reflect higher than expected employee departures resulting in a $5.0 million decrease to long-term incentive compensation expense.

Recent Accounting Pronouncements

Information regarding accounting pronouncements that have been issued but not yet adopted by the Company is incorporated by reference from Part II, Item 8, Financial Statements and Supplemental Data, Note 3 — Recent Accounting Pronouncements, of this Annual Report on Form 10-K.

ITEM 7(A).    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following information, together with information included in other parts of this Management's Discussion and Analysis of Financial Condition and Results of Operations, describes the key aspects of certain financial instruments that have market risk to Janus.

Investment Management Fees

Revenues are generally based upon a percentage of the market value of assets under management and are calculated as a percentage of the daily average asset balance in accordance with contractual agreements with the Company's investment advisory clients. Assets under management primarily include domestic and international equity and debt securities. Accordingly, fluctuations in the financial markets have a direct effect on Janus' operating results. In addition, fluctuations in interest rates may affect the value of assets under management in the money market and other fixed income investment products. The graph in Item 7, Management Discussion and Analysis of Financial Condition and Results of Operations — Investment Management Operations presents the direct historical relationship between revenue and average assets under management.

Performance Fees

Performance fee revenue is derived from certain private accounts primarily within the risk-managed discipline and from certain mutual funds. Janus recognized performance fees of $19.5 million, $14.9 million and $26.8 million in 2007, 2006 and 2005, respectively.

26

---

Private account performance fees are specified in client contracts and are based on investment performance as compared to an established benchmark index over a specified period of time. Performance fees are recognized at the end of the contractual period if the stated performance criteria are achieved. At December 31, 2007, $10.4 billion of assets under management were subject to private account performance fees.

Mutual fund performance fees were recorded beginning in the first quarter 2007. The investment management fee paid by each fund is the base management fee plus or minus a performance fee adjustment as determined by the relative investment performance of each fund compared to a specified benchmark index. The performance fee adjustment is up to 15 basis points, calculated using each fund's daily net average assets over the performance period. The measurement period began as a trailing 12-month period and each subsequent month will be added to each successive measurement period until a 36-month period is achieved in the first quarter 2009. At that point, the measurement period will become a rolling 36-month period. At December 31, 2007, $21.9 billion of assets under management were subject to mutual fund performance fees.

Trading Securities

At December 31, 2007, investments classified as trading totaled $104.3 million, representing $38.9 million of securities held in separately managed accounts and $65.4 million of securities held in the portfolios of advised funds consolidated by the Company. Trading securities are carried in Janus' consolidated financial statements at fair market value, with changes in value recognized as gains and losses currently in earnings.

Available-for-Sale Securities

At December 31, 2007, investments classified as available-for-sale totaled $106.4 million, representing $16.1 million of investments in advised funds and $90.3 million of SIV securities issued by Stanfield. Investments in advised funds are carried in Janus' consolidated financial statements at fair market value and are subject to market fluctuations and the performance of the underlying investment securities. SIV securities are carried in Janus' consolidated financial statements based on Janus' estimate of fair market value. (See Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations).

Held-to-Maturity Securities

There were no securities classified as held-to-maturity at December 31, 2007. At December 31, 2006, Janus' held-to-maturity investments totaled $69.8 million in U.S. government and agency debt and $11.4 million in highly rated corporate debt. Held-to-maturity securities are stated at cost with corresponding premiums or discounts amortized over the life of the investment to other income.

Foreign Currency Exchange Sensitivity

Janus has international subsidiaries that conduct business within other foreign countries. With respect to these operations, matters arise as to financial accounting and reporting for foreign currency transactions and for translating foreign currency financial statements into U.S. dollars. The exposure to foreign currency fluctuations is not material as the majority of the revenue earned by international subsidiaries is denominated in U.S. dollars.

Interest Rate Risk on Long-Term Debt

Janus is not exposed to interest rate risk other than from the potential change in interest rates on the Company's debt in the event of a change in credit ratings by Moody's or S&P. All of Janus outstanding debt includes an interest rate adjustment covenant that provides that the interest rate payable will

27

---

increase by 25 basis points for each level that the Company's debt rating is decreased by Moody's from its existing rating of Baa3 or by S&P from its existing rating of BBB-, up to a maximum increase of 200 basis points. If at any time after the interest has been adjusted upward; either Moody's or S&P increases its rating, then for each level of such increase in the rating, the interest payable will be decreased by 25 basis points, but in no event to a rate less than the interest rate payable on the date of their issuance. The interest rate adjustment covenant will permanently terminate if the Company's debt ratings increase to Baa2 by Moody's and BBB by S&P (or higher), with a stable or positive outlook regardless of any subsequent decrease in the ratings by either or both rating agencies.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Janus Capital Group Inc.

We have audited the accompanying consolidated balance sheets of Janus Capital Group Inc. and subsidiaries (the "Company") as of December 31, 2007 and 2006, and the related consolidated statements of income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2007. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2007 and 2006, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2007, in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 12 to the consolidated financial statements, the Company changed its method of accounting for uncertain tax positions on January 1, 2007 in accordance with the Financial Accounting Standard Board's Interpretation No. 48, Accounting for Uncertainty in Income Taxes.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2007, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 28, 2008 expressed an unqualified opinion on the Company's internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Janus Capital Group Inc.

We have audited the internal control over financial reporting of Janus Capital Group Inc. and subsidiaries (the "Company") as of December 31, 2007, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the accompanying consolidated financial statements as of and for the year ended December 31, 2007 of the Company and our report dated February 28, 2008 expressed an unqualified opinion on those financial statements and included an explanatory paragraph regarding the Company's adoption on January 1, 2007 of the Financial Accounting Standard Board's Interpretation No. 48, Accounting for Uncertainty in Income Taxes.

MANAGEMENT REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Janus Capital Group Inc. ("Janus") management is responsible for establishing and maintaining adequate internal control over Janus' financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Janus' internal control system was designed to provide reasonable assurance to Janus' management and board of directors regarding the preparation and fair presentation of published financial statements. There are inherent limitations in the effectiveness of any internal control, including the possibility of human error and the circumvention or overriding of controls. Accordingly, even effective internal controls can provide only reasonable assurances with respect to financial statement preparation. Further, because of changes in conditions, the effectiveness of internal controls may vary over time.

Janus has assessed the effectiveness of Janus' internal controls over financial reporting as of December 31, 2007. In making this assessment, Janus used the criteria set forth in the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework.

Based on the assessment using those criteria, Janus believes that, as of December 31, 2007, internal control over financial reporting is effective.

Janus' independent registered public accounting firm audited the financial statements included in the Annual Report on Form 10-K and have issued an audit report on management's assessment of Janus' internal control over financial reporting. This report appears on page 31 of this Annual Report on Form 10-K.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — DESCRIPTION OF THE BUSINESS

Janus Capital Group Inc. and its subsidiaries (collectively, "Janus" or the "Company") derive revenue and net income from providing investment management, administration, distribution and related services to individual and institutional investors through mutual funds, subadvised relationships and separate accounts (collectively referred to herein as "investment products") in both domestic and international markets. Revenue is largely dependent on the total value and composition of assets under management, which include domestic equity, international equity and debt securities. Accordingly, fluctuations in the financial markets and in the composition of assets under management affect revenue and operating results. A significant portion of Janus' revenue is derived from contracts to manage mutual funds which are subject to annual review and approval by each fund's Board of Trustees and/or its shareholders.

Janus' significant subsidiaries and one equity method investment at December 31, 2007, include:

•

Janus Capital Management LLC ("JCM") (wholly-owned subsidiary).  JCM offers growth equity, core and international equity funds, as well as balanced, specialty fixed-income and money market funds.

•

Enhanced Investment Technologies, LLC ("INTECH") (approximate 87% owned subsidiary).  INTECH offers risk-managed investment products that are based on a mathematical theorem that attempts to capitalize on the volatility in stock price movements. INTECH's goal is to achieve long-term returns that outperform a passive index, while controlling risks and trading costs. INTECH manages institutional and private accounts and subadvises certain Janus mutual funds.

•

Perkins, Wolf, McDonnell and Company, LLC ("PWM") (approximate 30% ownership, accounted for under the equity method).  PWM subadvises certain of Janus' small- and mid-cap value mutual funds.

•

Capital Group Partners, Inc. ("CGP") (wholly-owned subsidiary).  The operating business of CGP, Rapid Solutions Group ("RSG") provides printing and fulfillment services and graphic design capabilities, with a client concentration in the financial services industry. During the third quarter 2007, Janus initiated a plan to dispose of RSG and has classified the related operations as discontinued. (See Note 7).

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The financial statements include all majority-owned subsidiaries and all intercompany accounts and transactions have been eliminated. The equity method of accounting is used for PWM as Janus has significant influence but does not have the ability to exercise control.

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentation. On the Consolidated Statements of Income, mutual fund investigation charges, net of recoveries, which were previously separately presented, are now included in general, administrative and occupancy. Investment gains, net, which were previously included in other income, net are now separately presented. All balances and activity associated with RSG have been reclassified to separately present continuing and discontinued operations.

37

---

Accounting Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Janus' significant estimates relate to income taxes, intangible assets and goodwill, marketable securities and equity compensation.

Segment Information

During the third quarter 2007, the Printing and Fulfillment segment, represented by RSG, was reclassified to discontinued operations. The Company now operates one business segment, its Investment Management operations.

Cash and Cash Equivalents

Short-term liquid investments with an initial maturity of generally three months or less, including investments in money market funds, are considered cash equivalents.

Property and Equipment

Property and equipment is recorded at cost. Depreciation and amortization is recorded using the straight-line method over the estimated useful life of the related assets (or the lease term, if shorter). Depreciation and amortization expense totaled $14.2 million, $13.8 million and $13.4 million for the years ended December 31, 2007, 2006 and 2005, respectively. Property and equipment is summarized as follows (in millions):

Janus evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The evaluation is based on an estimate of the future cash flows expected to result from the use of the asset and its eventual disposition. If expected future undiscounted cash flows are less than the carrying amount of the asset, an impairment loss is recognized to the extent that the carrying amount of the asset exceeds its fair value.

Software

Purchased software is recorded at cost and amortized over its estimated useful life. Computer software and development costs incurred in the preliminary project stage, as well as training and maintenance costs, are expensed as incurred. Direct and indirect costs associated with the application development stage of internal use software are capitalized until such time that the software is substantially complete and ready for its intended use. Capitalized costs are amortized on a straight-line basis over the estimated useful life of the software.

38

---

Deferred Commissions

Sales commissions paid to financial intermediaries on sales of certain mutual fund shares are deferred and amortized over various periods, not exceeding four years, based on the estimated recoverability of the asset through distribution fee payments or contingent deferred sales charges. Contingent deferred sales charges received from early withdrawal charges reduce the unamortized deferred commissions balance. Amortization expense for the years ended December 31, 2007, 2006 and 2005 totaled $8.9 million, $7.8 million and $16.2 million, respectively. Deferred commissions, which are recorded as a component of other assets, are summarized as follows (in millions):

Marketable Securities

Janus classifies marketable securities as trading, available-for-sale or held-to-maturity at the time of purchase and periodically re-evaluates such classifications. Trading securities are carried at fair value and consist primarily of investments in debt and equity securities held in the portfolios of consolidated advised funds and other debt and equity securities in separate accounts. Changes in the fair value are reflected as a component of investment gains, net on the consolidated statements of income.

Marketable securities classified as available-for-sale consist of investments in advised funds and other securities and are carried at fair value. Changes in fair value are reflected as a component of accumulated other comprehensive income until realized. Realized gains, losses and declines in fair value that are judged to be other-than-temporary are reflected as a component of investment gains, net on the consolidated statements of income. Realized gains and losses are determined using the first in, first out cost method.

Fair value of trading and available-for-sale securities is determined using observable market data based on recent trading activity. Where observable market data is unavailable due to a lack of trading activity, Janus utilizes independent third parties or internally developed models to estimate fair value. Estimating fair value requires significant management judgment, including benchmarking to similar instruments with observable market data and applying appropriate discounts that reflect differences between the securities that Janus is valuing and the selected benchmark. Depending on the type of securities owned by Janus, other valuation methodologies may be required.

Marketable securities are classified as held-to-maturity when Janus has the intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at cost with corresponding premiums or discounts amortized over the life of the investment to other income. Realized gains, losses and declines in fair value that are judged to be other-than-temporary are reflected as a component of investment gains, net on the consolidated statements of income.

Janus periodically evaluates the carrying value of investment securities classified as available-for-sale or held-to-maturity for potential impairment. In determining if an impairment exists, Janus considers the duration, extent and circumstances of any decline in fair value. If the decline in value is determined to be other than temporary, the carrying value of the security is written down to fair value with the loss recognized currently in earnings.

39

---

Income Taxes

Deferred income tax assets and liabilities are recorded for the temporary differences between the financial statement and income tax bases of assets and liabilities as measured by the enacted income tax rates that may be in effect when these differences reverse. Significant management judgment is required in developing Janus' provision for income taxes, including the valuation allowances that might be required against deferred tax assets and the evaluation of various income tax contingencies.

Goodwill and Intangible Assets

Goodwill represents the excess of cost over the fair value of the identifiable net assets of acquired companies. Goodwill is tested annually for impairment and is not amortized. Janus' identifiable intangible assets generally represent the cost of client relationships and management contracts acquired. Goodwill and indefinite-lived intangible assets are tested for impairment annually, or more frequently if events or circumstances indicate that the asset might be impaired. Intangibles subject to amortization are tested for impairment whenever events or circumstances indicate that the asset may be impaired. Goodwill and intangible assets require significant management estimates and judgment, including the valuation and expected life determination in connection with the initial purchase price allocation and the ongoing evaluation for impairment.

Revenue Recognition

Investment management and shareholder servicing fees are recognized as services are provided. These revenues are generally determined in accordance with contracts based upon a percentage of assets under management.

Performance fees are based on the performance of certain investment products as compared to an established benchmark over a specified period of time and are recognized at the end of the period if the stated performance criteria are achieved.

Marketing

Marketing and promotional costs are expensed as incurred.

Stock-Based Compensation

Stock-based compensation cost is based on the grant date fair value of awards expected to vest at the end of the stated service period, comprised of the total value of the awards less an estimate for forfeitures. The grant date fair value of stock options is determined using the Black-Scholes option pricing model and the grant date fair value of restricted stock is determined from a quoted market price. The Black-Scholes model requires significant management estimates including volatility and expected life.

Other Income

The components of other income are as follows (in millions):

40

---

Other Comprehensive Income

The components of other comprehensive income include the change in fair market value of available-for-sale investments owned by Janus as well as foreign currency translation adjustments, as follows (in millions):

NOTE 3 — RECENT ACCOUNTING PRONOUNCEMENTS

On September 15, 2006, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standard No. 157, "Fair Value Measurements" ("SFAS 157"), which defines and establishes a framework for measuring fair value and expands disclosures regarding fair value measurements. The effective date of SFAS 157 is the Company's fiscal year beginning January 1, 2008. The adoption of SFAS 157 is expected to result in additional disclosures regarding Janus' fair value measurements in future filings.

On February 15, 2007, the FASB issued Statement of Financial Accounting Standard No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("SFAS 159"), which permits an entity to measure certain financial assets and financial liabilities at fair value. The effective date of SFAS 159 is the Company's fiscal year beginning January 1, 2008. Janus has not elected the fair value option for any assets or liabilities that are not otherwise required to be accounted for at fair value by existing accounting standards.

On December 4, 2007, the FASB issued Statement of Financial Accounting Standard No. 141 (revised 2007), "Business Combinations" ("SFAS 141R"), which establishes principles and requirements for how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in an acquiree, including the recognition and

41

---

measurement of goodwill acquired in a business combination. The effective date of SFAS 141R is the Company's fiscal year beginning January 1, 2009. Janus has not yet completed an assessment of the impact of SFAS 141R.

On December 4, 2007, the FASB issued Statement of Financial Accounting Standard No. 160 "Noncontrolling Interests in Consolidated Financial Statements- an amendment of Accounting Research Bulletin No. 51" ("SFAS 160"), which establishes accounting and reporting standards for the noncontrolling interest in a subsidiary, deconsolidation of a subsidiary and requires noncontrolling interests to be classified as a component of equity in the consolidated financial statements. The effective date of SFAS 160 is the Company's fiscal year beginning January 1, 2009. Janus has not yet completed an assessment of the impact of SFAS 160.

NOTE 4 — EARNINGS PER SHARE

Basic earnings per common share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per common share adjusts the weighted average shares outstanding by the dilutive impact of shares underlying stock options and unvested restricted stock awards. The following is a summary of the earnings per share calculation (in millions, except per share data):

The following stock options and unvested restricted stock are anti-dilutive and have not been included in the weighted average diluted shares outstanding calculation:

All shares held in the Janus Employee Stock Ownership Plan (the "ESOP") are treated as outstanding for purposes of computing basic earnings per share.

In the fourth quarter 2007, Janus evaluated its seed capital investments and determined that mutual funds and separate accounts in which it owns a majority interest should be consolidated. Securities underlying consolidated mutual funds and separate accounts have been classified as trading with changes in market value reported in earnings.

Proceeds from the sale of available-for-sale securities totaled $28.7 million, $59.9 million and $67.7 million for the years ended December 31, 2007, 2006 and 2005, respectively.

Unrealized gains on trading securities held at December 31, 2007, totaled $3.4 million.

Structured Investment Vehicles ("SIVs")

A SIV is a fund that seeks to generate investment returns through yield curve arbitrage by purchasing high grade medium- and long-term fixed income instruments and funding those purchases by issuing low cost, short-term senior debt instruments such as asset-backed commercial paper and asset-backed medium term notes. In late 2007, widespread illiquidity in the commercial paper and capital markets prevented SIVs from accessing necessary funding for ongoing operations. The securities issued by those SIVs that were unable to access necessary liquidity through banks or other large financial institutions were generally downgraded by rating agencies as a result of expected defaults on maturing securities.

While Janus does not sponsor or serve as asset manager to any SIVs, it does serve as investment adviser to certain money market funds (the "Funds") that have invested in securities issued by SIVs from time to time, including securities issued by Stanfield Victoria Funding LLC ("Stanfield securities"). On December 21, 2007, Moody's Investors Service, Inc. ("Moody's") downgraded the Stanfield securities to a rating below what is generally permitted to be held by a security in the Funds. In connection with this downgrade, Janus purchased all of the Stanfield securities held by the Funds, totaling $108.5 million, to protect investors in the Funds from possible losses associated with such downgrade.

Subsequent to the purchase, Janus undertook a detailed analysis of the assets underlying the Stanfield securities, many of which do not have readily determinable fair values, and estimated a range of fair value by benchmarking those assets against instruments of a similar type with comparable yields,

43

---

maturities and credit ratings for which fair market values were readily available. As a result of this analysis, Janus recognized an $18.2 million impairment charge (including $3.5 million of purchased accrued interest), reflecting the difference between the estimated fair value and the purchase price of the Stanfield securities.

In January 2008, the Stanfield securities were placed with an enforcement manager to be restructured or sold at the election of each senior note holder. Janus elected to participate in the restructuring of the Stanfield securities. In addition, the collateral agent, Deutsche Bank, filed an interpleader complaint due to conflicting positions of note holders that has effectively prevented the enforcement manager from making any cash payments and other distributions, or from restructuring the Stanfield securities, until the matter is resolved by the New York courts or is settled among the parties. Janus management believes that the anticipated restructuring will likely result in extended maturities and/or a pro-rata distribution of proceeds from the income and principal payments on the assets underlying the Stanfield securities. Given the uncertainty of the restructuring at this time, Janus can not determine the potential impact that a restructuring will have on the value of the Stanfield securities.

Janus may recognize additional impairment charges on the Stanfield securities if the restructuring is unsuccessful or there is an other-than-temporary deterioration in the value of the underlying assets. Janus' total additional risk of loss with respect to the Stanfield securities is limited to the $90.3 million carrying value of its investment.

NOTE 6 — ACQUISITIONS OF MINORITY INTEREST

Janus has increased its ownership of INTECH with the following purchases (in millions, except ownership %):

							Purchase Price Allocation
Acquisition Date		Interest Acquired		Purchase Price			Goodwill			Intangible Assets
March 30, 2007		4	%	$	81.0		$	49.3		$	31.7
February 1, 2006		5	%	$	90.0		$	54.8		$	35.2

Intangible assets acquired represent customer relationships which are amortized over 12 years.

The pro forma results of operations have not been presented as they would not have been materially different from reported amounts.

NOTE 7 — DISCONTINUED OPERATIONS

During the third quarter 2007, Janus initiated a plan to dispose of RSG, previously reported as the Printing and Fulfillment segment, as a result of RSG's difficulty in growing the business and Janus' desire to focus on its core investment management business.

Janus assessed the fair value of RSG less estimated disposal costs and concluded that the carrying value of RSG had been impaired. The fair value of RSG at December 31, 2007, was estimated using preliminary bids received from potential buyers. Impairment charges totaling $67.1 million (net of a $6.2 million tax benefit) were recorded to write-down the carrying value of RSG to the estimated fair market value less costs to sell the business. The impairment charges were allocated as follows; $57.8 million to goodwill (for which no tax benefit has been recorded), $3.7 million to property and equipment, and $5.6 million of intangible assets.

The following is a summary of identified intangible assets (in millions):

Client relationships are amortized over their estimated lives of seven to 25 years using the straight-line method. Amortization expense was $10.7 million, $10.4 million and $6.3 million for the years ended December 31, 2007, 2006 and 2005, respectively. Amortization expense over the next five years is expected to be $11.4 million in 2008, $10.1 million in 2009, $9.8 million in 2010, $9.8 million in 2011 and $9.8 million in 2012.

The majority of goodwill and intangible assets were generated from transactions in 2001 to buy out the minority interest of JCM and resulted in the recognition of $803.8 million of goodwill and $1,164.6 million of intangible assets, representing mutual fund advisory contracts, brand name, trademark and client relationships.

Acquisitions of interests in INTECH resulted in goodwill of $185.0 million and intangible assets of $109.4 million, representing client relationships.

NOTE 9 — RESTRUCTURING AND ASSET IMPAIRMENT CHARGES

Intangibles Impairment

Within client relationships, Janus has subadvised contracts that have an allocated intangible value. To the extent such subadvised contracts are terminated, Janus recognizes an impairment charge equal to the unamortized value of the intangible asset recorded for such contract. Janus recognized impairment charges on subadvised contracts of $0.4 million and $11.0 million for the years ended December 31, 2007 and 2006, respectively. There were no impairments of subadvised contracts in 2005.

Bay Isle Financial LLC ("Bay Isle")

In 2005, Janus closed the California operations of Bay Isle, an asset management firm that focused on value and real estate investment trust investing. As a result of the transactions, Janus recognized a charge of $1.6 million, representing lease termination costs, severance payments and fixed asset impairments, and an intangible asset impairment of $3.9 million.

NOTE 10 — OTHER BALANCE SHEET CAPTIONS

Other current assets are composed of the following (in millions):

NOTE 11 — LONG-TERM DEBT

Long-term debt at December 31, 2007 and 2006, consisted of the following (in millions):

Fair Value of Long-Term Debt

The fair value of long-term debt was calculated using market quotes or, if market quotes were not available, by discounting future cash flows using market interest rates for debt with similar terms and maturities.

6.250% Senior Notes Due 2012 and 6.700% Senior Notes Due June 15, 2017

On June 14, 2007, Janus issued $300.0 million of 6.250% Senior Notes due June 15, 2012, and $450.0 million of 6.700% Senior Notes that are due June 15, 2017 (collectively, the "2007 senior notes") and are not callable by Janus or redeemable by the holders prior to maturity. Interest is paid semiannually on June 15 and December 15 of each year. The proceeds from the 2007 senior note issuances were $748.4 million. On June 26, 2007, approximately $160.0 million of the total proceeds were used to repay the 7.875% Senior Notes due 2032 plus accrued and unpaid interest as of the redemption date. The remaining proceeds may be used for possible future acquisitions, the repurchase of Janus' common stock, and/or general corporate purposes.

If the Company experiences a change of control and the 2007 senior notes are rated below investment grade by Standard & Poor's Rating Service ("S&P") and Moody's, the Company must offer to repurchase all of the 2007 senior notes at a price equal to 101% of the principal amount plus accrued and unpaid interest to the repurchase date.

5.875% Senior Notes Due 2011

On September 18, 2006, Janus issued $275.0 million of 5.875% senior notes that are due September 15, 2011, and are not callable by Janus or redeemable at the option of the holders prior to maturity. Interest is paid semiannually on March 15 and September 15.

On May 2, 2006, Janus entered into a pay-fixed receive-variable interest rate swap (the "Swap") in anticipation of a $272.0 million fixed rate debt issuance with a mandatory termination date of May 4, 2007. The Swap was designated and accounted for as a cash flow hedge under SFAS No. 133 (as amended and interpreted) "Accounting for Derivatives and Hedging Activities" ("SFAS 133"), and was designed to hedge the variability in interest payments on the anticipated fixed rate debt as a result of changes in the interest rate between inception of the Swap and the issuance of the debt. On September 18, 2006, the Swap was terminated and Janus incurred a loss of $4.4 million, or $2.7 million net of tax, which has been recorded in accumulated other comprehensive income on the consolidated balance sheet and will be amortized to interest expense over the life of the 5.875% senior notes.

6.119% Senior Notes Due 2014

On April 26, 2004, Janus issued $527.4 million of 6.119% senior notes that are due April 15, 2014, in exchange for $465.1 million of senior notes (composed of $286.9 million of the 7.000% senior notes and $178.2 million of the 7.750% senior notes). The 6.119% senior notes pay interest semiannually on April 15 and October 15. On May 19, 2004, Janus' wholly-owned subsidiary, CGP, exercised its right to repurchase $445.0 million aggregate principal amount of the 6.119% senior notes. This transaction resulted in a non-operating charge of $55.5 million, primarily related to the premium paid to exchange the old notes for the new notes given declines in interest rates. As CGP owns the $445.0 million of repurchased notes, Janus makes regular interest payments to CGP. Such payments are eliminated in consolidation.

7.750% Senior Notes Due 2009

On July 2, 2002, Janus issued 7.750% senior notes that are due June 15, 2009, and are not callable by Janus or redeemable by the holders prior to maturity. Interest is paid semiannually on June 15 and December 15.

Interest Rate Adjustment Covenant

All of Janus' outstanding debt includes an interest rate adjustment covenant that provides that the interest rate payable will increase by 25 basis points for each level that the Company's debt rating is decreased by Moody's from its existing rating of Baa3 or by S&P from its existing rating of BBB-, up to a maximum increase of 200 basis points. If at any time after the interest has been adjusted upward; either Moody's or S&P increases its rating, then for each level of such increase in the rating, the interest payable will be decreased by 25 basis points, but in no event to a rate less than the interest rate payable on the date of their issuance. The interest rate adjustment covenant will permanently terminate if the Company's debt ratings increase to Baa2 by Moody's and BBB by S&P (or higher), with a stable or positive outlook regardless of any subsequent decrease in the ratings by either or both rating agencies.

Credit Facility

On June 1, 2007, the Company and the syndicate of banks amended the then existing $200 million Three-Year Competitive Advance and Revolving Credit Facility Agreement (the "Credit Facility"). Under the amended Credit Facility, the bank syndicate's commitment was increased to $350 million and the maturity date was extended from October 19, 2008 to June 1, 2012. The Credit Facility contains a

48

---

number of financial covenants including a specified financing leverage ratio and interest coverage ratio. At December 31, 2007, there were no borrowings under the Credit Facility.

Aggregate Maturities of Indebtedness

The aggregate amounts of debt maturing in the next five years are as follow (in millions):

NOTE 12 — INCOME TAXES

Janus' provision for income taxes is summarized as follows (in millions):

---

Janus' deferred income tax liabilities (assets) are summarized as follows (in millions):

The current deferred income tax amounts at December 31, 2007 and 2006, are included within other current assets. Deferred tax assets and liabilities are reflected on the balance sheet as follows (in millions):

Janus' effective income tax rate differs from the statutory federal income tax rate as follows:

Janus adopted the provisions of Financial Accounting Standards Board Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" ("FIN 48"), on January 1, 2007, which sets forth a specific method for the financial statement recognition and measurement of a tax position taken or expected to be taken on a tax return. As a result of the implementation of FIN 48, Janus reduced its tax contingencies liability by $29.3 million, which had previously been accounted for under the provisions of Statement of Financial Accounting Standard No. 5, "Accounting for Contingencies." The reduction in the liability and the related change in deferred taxes were accounted for as an increase to

50

---

retained earnings on January 1, 2007. The tax contingencies liability has been recorded in other long-term liabilities. A reconciliation of the beginning and ending liability is as follows (in millions):

A deferred tax asset of $12.5 million has been recorded associated with the tax contingencies liability. If the tax contingencies liability and related deferred tax asset are reversed in future periods, the effective tax rate would be favorably impacted by $22.2 million.

Tax returns filed in previous years are subject to audit by various federal, state and international taxing authorities and as a result of such audits, additional tax assessments may be proposed. As of December 31, 2007, the majority of tax years from 1996 and forward remain subject to audit. Based on information currently available, Janus management does not anticipate any material changes in the liability within the next twelve months.

Taxing authorities generally charge interest and may assess penalties in the event that a tax position taken is subsequently reversed upon examination. Janus has accrued interest on its uncertain tax provisions based on the rates specified by the applicable taxing authorities and has recorded the interest as a component of the tax provision. At December 31, 2007, $10.9 million of accrued interest is included in the liability for tax contingencies. Any potential penalties associated with a tax contingency will also be included as a component of the tax provision in the period in which the assessment of a penalty becomes likely. Janus does not believe that it is subject to any penalties related to its tax contingencies and therefore, has not accrued a liability for tax penalties.

In the event of an overpayment of income taxes, taxing authorities generally pay interest from the date of the overpayment through the date on which an amended return is filed. Janus records interest income from taxing authorities as a component of the tax provision.

NOTE 13 — LONG-TERM INCENTIVE COMPENSATION

The components of Janus' long-term incentive compensation expense are summarized as follows (in millions):

Historical long-term incentive awards have been granted with ratable vesting schedules of between three and five years. The majority of awards granted in 2007 and 2006 were granted with a four-year ratable vesting schedule, subject to accelerated vesting up to 50% if certain financial performance criteria are achieved. Based on such criteria, the 2007 and 2006 awards qualified for accelerated vesting of 45% and 50%, respectively, on February 1, 2008. At December 31, 2007, unrecognized compensation, net of estimated forfeitures, and the weighted-average years over which the

51

---

compensation cost will be recognized are summarized as follows (in millions and assuming no further accelerated vesting):

Janus generally grants annual long-term incentive awards in February of each year. The 2008 annual grant, not included in the table above, totaled $71.5 million and will be recognized ratably over a three-year period. The 2008 annual grant is not subject to performance-based accelerated vesting.

Stock Options

The fair value of stock options granted to Janus employees was estimated on the date of each grant using the Black-Scholes option pricing model with the following assumptions:

Expected volatility was determined using an average of Janus' historical volatility and industry and market averages, as appropriate. Expected life was determined using employee termination rates and vesting periods of each grant. The risk-free interest rate for periods within the contractual life of the options is based on the U.S. Treasury yield curve in effect at the time of each grant. Stock options granted prior to February 2005 have a maximum contractual term of 10 years and seven years for options granted thereafter.

Restricted Stock Awards

The table below summarizes unvested restricted stock awards for the years ended December 31, 2007 and 2006:

		2007					2006
		Shares		Weighted Average Grant-Date Fair Value			Shares		Weighted Average Grant-Date Fair Value
Unvested at January 1		2,820,345		$	19.07		4,500,158		$	21.22
Granted		1,035,246			21.76		839,878			21.52

Forfeited		(130,162	)		18.55		(536,623	)		23.02
Unvested at December 31		1,534,921		$	18.52		2,820,345		$	19.07

The total fair value of restricted stock that vested during the years ended December 31, 2007, 2006 and 2005, was $48.6 million, $44.3 million and $33.5 million, respectively.

Mutual Fund Units

During 2007 and 2006, Janus granted $26.5 million and $21.3 million, respectively, in awards that are indexed to certain mutual funds managed by the Company. Upon vesting, participants receive the value of the award adjusted for earnings or losses attributable to the mutual funds to which the award was indexed. At the time of grant, the Company creates a fair value hedge accounted for in accordance with SFAS 133 to protect against the market variability of the mutual funds to which the awards are indexed by making investments equal to the amount of the awards in the mutual funds selected by the participants. Subsequent changes in market value are recorded against the Company's asset with the offset to the mutual fund share award liability. Any hedge ineffectiveness will result in an increase or decrease in long-term incentive compensation expense. Hedge effectiveness is assessed quarterly and has been 100% effective since inception and therefore, no gain or loss has been recognized. At December 31, 2007, the notional amount of the fair value hedge is $35.8 million and represents the cost basis of unvested awards.

Forfeiture Estimate

Janus estimates, at the time of grant, the amount of awards that are not expected to vest based on historical forfeiture rates. As a result of higher than expected employee departures prior to vesting during the third quarter 2006, Janus revised the estimate of forfeitures related to long-term incentive compensation. The effect of increasing the forfeiture estimate was recorded as a $5.0 million decrease in long-term incentive compensation expense ($3.1 million net of tax) for the year ended December 31, 2006.

Long-Term Incentive Stock Plans

On May 10, 2005, Janus shareholders approved the 2005 Long-Term Incentive Stock Plan ("2005 Plan") which allows the Board of Directors to grant up to 15.0 million shares of equity-based awards, including stock options and restricted stock. The 2005 Plan replaced the 1998 Long-Term Incentive Plan ("1998 Plan") once the approximately 1.7 million shares remaining under the 1998 Plan are depleted. On January 25, 2007, Janus registered 15.0 million shares to be granted as equity awards under the 2005 Plan.

NOTE 14 — EMPLOYEE BENEFIT PLANS

Substantially all full-time employees of Janus are eligible to participate in a company-sponsored 401(k) and profit-sharing plan. Employees also participate in an ESOP. Janus matches a maximum of 3% of employee compensation in the 401(k) plan. Contributions to the ESOP and the profit-sharing plan are made at the discretion of the Board of Directors. Participants vest ratably in the ESOP and profit-sharing contributions over a five-year period. Expense related to the 401(k) plan, ESOP and profit-sharing plan was $12.5 million, $10.7 million and $9.0 million in 2007, 2006 and 2005, respectively.

The Company also has a deferred compensation plan for certain highly compensated employees. Eligible participants may defer a portion of their compensation and have the ability to earn a return by indexing their deferrals to mutual funds managed by the Company. The Company makes no contributions to the plan and is liable to the participants for the amount of the deferrals as adjusted for changes in market value. To protect against market variability of the liability, the Company creates a fair value hedge accounted for in accordance with SFAS 133 by investing in mutual funds that are consistent with the deferred amounts and mutual fund elections of the participants. Changes in market value are recorded to the investment asset held by the Company with the offset recorded to the liability to the participants. Any hedge ineffectiveness will result in increases or decreases in employee compensation and benefits expense. Hedge effectiveness is assessed quarterly and has been 100% effective since inception and therefore, no gain or loss has been recognized. At December 31, 2007, the notional amount of the fair value hedge is $9.0 million and represents total payroll deferrals.

NOTE 15 — COMMITMENTS AND CONTINGENCIES

Operating Leases

Janus rents office space and equipment under the terms of various operating lease agreements. As of December 31, 2007, future minimum rental commitments under non-cancelable operating leases are as follows (in millions):

Rent expense was $14.8 million, $15.2 million and $15.0 million in 2007, 2006 and 2005, respectively.

Investment Management Contracts

Most of Janus' revenues are derived pursuant to investment advisory agreements with its investment advisory clients. Investment advisory agreements with mutual funds may be terminated by either party with notice, or terminated in the event of an "assignment" (as defined in the Investment Company Act of 1940 as amended (the "1940 Act")), and must be approved and renewed annually by the disinterested members of each fund's trustees, or its shareowners, as required by law. Generally, any change in control of Janus would constitute an "assignment" under the 1940 Act. In addition, a mutual fund's trustees or directors may terminate these investment advisory agreements upon written notice for any reason.

55

INTECH Minority Interest

Each fiscal year beginning in 2008 and terminating in 2012, each of the two INTECH founding members has the option to require Janus to purchase up to approximately 25% of their current holdings of INTECH shares ("Annual Option Shares") at the fair market value on the date of exercise based on a valuation by an independent investment bank. As of December 31, 2007, each of the two founders owns approximately 6% of INTECH. In the event that either INTECH founder does not fully exercise his annual voluntary sale option in a given year, Janus has the option to require the INTECH founder to sell the remaining balance of the Annual Option Shares at fair market value on the date of exercise.

In addition, each of the founders can require Janus to purchase their INTECH interests if the founder's employment is terminated. The purchase price of the departing founder's INTECH interests will be based on the fair market value on the date of exercise based on a valuation by an independent investment bank. Each founder is entitled to retain approximately one percent of INTECH's shares currently outstanding after employment until his death unless he is terminated for cause or leaves voluntarily while not in good standing. An INTECH founder will be deemed to be in good standing if he voluntarily leaves on or after January 1, 2009, after providing 12 months' prior notice and provided he cooperates with the transition. Janus has not recorded a liability for the purchase of the outstanding INTECH interests due to the uncertainty of this obligation and the price at which it may occur. INTECH interests in the aggregate would currently be valued at approximately $223.0 million, based on the most recent fair market value determined by an independent investment bank and agreed upon by INTECH and Janus.

NOTE 16 — LITIGATION

Janus is subject to various legal proceedings arising from normal business operations. Although there can be no assurances, based on information currently available, management believes that it is probable that the ultimate outcome of each of the actions will not have a material adverse effect on the consolidated financial condition of Janus. However, an adverse outcome in any of the actions could have a material adverse effect on the financial results of the Company in the period in which it is recorded. As of December 31, 2007, Janus had no litigation reserves as management believes that the remaining claims made in the civil actions described below have little or no merit and intends to defend against them.

Market Timing Litigation

Following the market timing investigations by the New York Attorney General ("NYAG") and the SEC, Janus and certain affiliates were named as defendants in a consolidated lawsuit in the U.S. District Court in Baltimore, Maryland (Case Number MDL No. 1586, 04-MD-15863). Five amended complaints were filed in these coordinated proceedings, including: (i) claims by a putative class of Janus fund investors 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 the Janus funds ostensibly on behalf of the Janus 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 on a derivative basis against Janus' Board of Directors (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 Janus shareholders 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).

56

---

In August 2005, the U.S. District Court entered orders dismissing most of the claims asserted against the Company and its affiliates by fund investors in the Marini and Steinberg cases described 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. The U.S. District Court also entered an order dismissing all claims in the Wiggins lawsuit. Plaintiffs have appealed that dismissal to the U.S. Court of Appeals for the Fourth Circuit. That appeal is currently pending. In August 2006, the U.S. District Court in the Wangberger 401(k) plan class action dismissed the action with prejudice, and the plaintiff appealed the dismissal to the U.S. Court of Appeals for the Fourth Circuit. That appeal is still pending. Finally, the U.S. District Court also dismissed the Chasen lawsuit against Janus' Board of Directors without leave to amend, ruling that the plaintiff had failed to make a pre-suit demand on the Board of Directors as required by applicable state law. The time to appeal this dismissal has expired. As a result of the above events, the Company and JCM are the remaining defendants, in some capacity, in one or more of the actions described in the preceding paragraph.

The Auditor of the State of West Virginia, in his capacity as securities commissioner, initiated administrative proceedings against many of the defendants in the market timing cases (including Janus) and seeks 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). In September 2006, Janus filed its answer to the Auditor's summary order instituting proceedings, and requested a hearing. A hearing was held in June 2007 during which the parties were ordered to submit a scheduling order. In addition to the currently pending Motion to Discharge Order to Show Cause, Janus continues to challenge the statutory authority of the Auditor to bring such an action.

Miscellaneous Proceedings

During 2007, two former portfolio managers filed suit against a Janus subsidiary, alleging that it implemented certain changes to their compensation arrangements in violation of prior agreements (Edward Keely v. Janus Management Holdings Corporation, Denver District Court, Case No. 2007 CV 7366 and Tom Malley v. Janus Management Holdings Corporation, Denver District Court, Case No. 2007 CV 10719). Janus answered the complaints, denying any liability and challenging the merits of Mr. Keely's and Mr. Malley's allegations. Trial for the suit brought by Mr. Keely has been postponed from its originally scheduled date of June 2008. A trial date for the suit brought by Mr. Malley has not yet been scheduled.

Certain officers and directors of Janus are also officers, directors and/or trustees for the various registered investment companies for which Janus acts as investment adviser.

NOTE 18 — SHAREHOLDER RIGHTS PLAN

Janus entered into the Shareholder Rights Plan ("Rights Plan") with UMB Bank, N.A., as rights agent as of June 14, 2000. Effective October 2, 2006, UMB Bank, N.A. was replaced as rights agent by Wells Fargo Bank N.A. In connection with the Rights Plan, the Janus Board declared a dividend of one right ("Right") for each outstanding share of Janus common stock as of the close of business on June 14, 2000 (the "Rights Record Date"). The Rights are not exercisable or transferable separately from the shares of Janus common stock until the earlier of: (i) 10 days following a public announcement that a person or group has acquired or obtained the right to acquire beneficial ownership of 15% or more of the outstanding shares of Janus common stock (unless beneficial ownership of 15% or more is a result of Company repurchases of its own stock), or (ii) 10 days following the commencement or announcement of an intention to make a tender or exchange offer that would result in an acquiring person or group beneficially owning 15% or more of the outstanding shares of Janus common stock (an "Acquiring Person"), unless the Janus Board sets a later date in either event (the earlier of (i) or (ii) being the "Rights Distribution Date"). Under the Rights Plan, the Janus Board has the option to redeem the Rights at a nominal cost or prevent the Rights from being triggered by designating certain offers for all the outstanding Janus common stock as Permitted Offers (as defined in the Rights Plan). No supplement or amendment may be made to the Rights Plan which changes the Redemption Price, the Final Expiration Date, the Purchase Price (as those terms are defined in the Rights Plan) or the number of ¹/₁₀₀₀ths of a share of Preferred Stock for which a Right is exercisable. Subject to the foregoing, prior to the Rights Distribution Date, Janus may amend or supplement the Rights Plan without the consent of any of the holders of the Rights. Following the Rights Distribution Date, the Rights Plan may be amended to cure any ambiguity, correct or supplement any provision that is defective or inconsistent with any other provision of the Rights Plan, or change or supplement any provision so long as such amendment or supplement does not adversely affect the holders of the Rights (other than an Acquiring Person or group). The Rights expire 10 years after the Rights Record Date unless earlier redeemed by Janus.

The Rights, when exercisable, entitle their holders (other than those held by an Acquiring Person) to purchase ¹/₁₀₀₀th of a share of Series A Janus Preferred Stock (subject to adjustment) or, in certain instances, other securities of Janus, including Janus common stock, having a market value equal to twice the exercise price of the Right. In certain circumstances, if Janus is involved in a merger or consolidation and is not the surviving entity or disposes of more than 50% of its assets or earnings power, the Rights also entitle their holders (other than an acquiring person or group) to purchase the highest priority voting shares in the surviving entity or its affiliates having a market value of two times the exercise price of the Rights.

The Rights Plan is intended to encourage a potential Acquiring Person or group to negotiate directly with the Janus Board of Directors but may have certain anti-takeover consequences. The Rights Plan could significantly dilute the interests in Janus of an Acquiring Person. The Rights Plan may therefore have the effect of delaying, deterring or preventing a change in control of Janus.

The Janus Board evaluates the Rights Plan every three years, and in October 2007 approved the continuation of the Rights Plan until the Rights expire.

As of December 31, 2007, Janus' management evaluated the effectiveness of the design and operation of its disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Disclosure controls and procedures are the controls and other procedures that the Company designed to ensure that it records, processes, summarizes and reports in a timely manner the information it must disclose in reports that it files with or submits to the SEC. Gary D. Black, Chief Executive Officer, and Gregory A. Frost, Executive Vice President and Chief Financial Officer, reviewed and participated in this evaluation. Based on this evaluation, Messrs. Black and Frost concluded that, as of the date of their evaluation, Janus' disclosure controls and procedures were effective.

There has been no change in Janus' internal controls over financial reporting (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) during the fourth quarter of 2007 that has materially affected, or is reasonably likely to materially affect, Janus' internal controls over financial reporting.
