BASIS OF PRESENTATION
BASIS OF PRESENTATION
	Note 1 — Basis of Presentation
	In the opinion of Janus Capital Group Inc. (collectively, “JCG” or “the Company”) management, the accompanying interim condensed consolidated financial statements contain all adjustments necessary to fairly present the financial position, results of operations and cash flows of JCG in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All such adjustments are of a normal recurring nature. Such interim condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Events subsequent to the balance sheet date have been evaluated for inclusion in the accompanying condensed consolidated financial statements through the issuance date and the Company has determined that there were no subsequent events that require disclosure. These interim condensed consolidated financial statements should be read in conjunction with JCG’s Annual Report on Form 10-K for the year ended December 31, 2014.
	The accompanying interim condensed consolidated financial statements have been prepared on a consistent basis with the accounting policies described in Note 2 to the consolidated financial statements that are presented in JCG’s Annual Report on Form 10-K for the year ended December 31, 2014.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued a new revenue recognition standard. The standard’s core principle is that a company will recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the standard specifies the accounting for certain costs to obtain or fulfill a contract with a customer and expands disclosure requirements for revenue recognition. The standard is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. On April 1, 2015, the FASB proposed a deferral of the effective date of the new revenue standard by one year; this proposal has not been finalized and will be subject to due process requirements, including a period for public comments. The Company is evaluating the effect of adopting this new accounting standard.
	In February 2015, the FASB issued amendments to its consolidation standard that eliminate the deferral for investment funds and modify the analysis for determining if an entity is a variable interest entity (“VIE”). The amendments also include a scope exception for money market funds and change how related party interests affect the consolidation analysis of VIEs. The amended VIE analysis changes the assessment of kick-out rights and fees paid to a service provider when decision-making over an entity’s most significant activities has been outsourced. Additionally, limited partnerships and similar entities will be considered VIEs under the amended standard unless limited partners hold substantive kick-out rights or participation rights. The standard is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. The Company is evaluating the effect of adopting this new accounting standard.
	In April 2015, the FASB issued an amendment to its debt standard requiring debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with the presentation of debt discounts and premiums. The standard is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. At March 31, 2015, the Company had approximately $2.5 million of debt issuance costs in other current and other non-current assets on its Condensed Consolidated Balance Sheets that meet the criteria of this amendment.

	The Company reviewed the gross unrealized losses on available-for-sale securities and determined that the losses were not other-than-temporary. No other-than-temporary impairment charges were recognized in the three months ended March 31, 2015 or 2014.
	Realized gains and losses related to the disposition of seeded investment products classified as available-for-sale securities were recognized within investment gains (losses), net on JCG’s Condensed Consolidated Statements of Comprehensive Income. The Company did not dispose of any seeded investment products classified as available-for-sale during the three months ended March 31, 2015. During the three months ended March 31, 2014, the Company realized losses of $0.1 million upon disposition of seeded investment products classified as available-for-sale securities.
	Derivative Instruments
	The Company maintains an economic hedge program that uses derivative instruments to hedge against market volatility of certain seed investments. Fluctuations in equity markets, debt markets and foreign currency markets are hedged by using index swaps, index futures and foreign currency forward contracts.
	JCG was party to the following derivative instruments as of March 31, 2015, and December 31, 2014:

	Index swaps are subject to a master netting arrangement. The values of the individual index swap contracts, including any associated cash collateral, are combined and are included on a net basis in other current assets on JCG’s Condensed Consolidated Balance Sheets. Index futures are also subject to a master netting arrangement and are presented in the same manner as the index swaps. Foreign currency forward contracts are not subject to a master netting arrangement, and as such, fair values of individual contracts are not netted and are included separately within either other current assets or other accrued liabilities on JCG’s Condensed Consolidated Balance Sheets.
	The Company posted $1.4 million and $1.7 million in cash collateral with the counterparty of the index futures as of March 31, 2015, and December 31, 2014, respectively. The cash collateral is included in other current assets on JCG’s Condensed Consolidated Balance Sheets.

	Level 1 Fair Value Measurements
	JCG’s Level 1 fair value measurements consist mostly of seeded investment products, investments in advised funds, investments in money market funds and investments related to deferred compensation plans with quoted market prices in active markets. The fair value level of seeded investment products classified as trading securities is determined by the underlying securities of the product. The fair value level of equity-method and unconsolidated seeded investment products are determined using the respective net asset value (“NAV”) of each product. All seeded investment products that use the NAV to determine their fair value are classified as Level 1 and primarily represent seeded mutual funds where JCG’s ownership level is under 50%.
	Level 2 Fair Value Measurements
	JCG’s Level 2 fair value measurements consist mostly of cash equivalents, seeded investment products and JCG’s long-term debt. Cash equivalents are short-term, highly liquid investments with an initial maturity of three months or less when purchased, and consist primarily of commercial paper and certificates of deposits. The fair value of consolidated seeded investment products where JCG’s ownership level is above 50% is determined by the underlying securities of the product. The fair value of JCG’s long-term debt is determined using broker quotes and recent trading activity, which are considered Level 2 inputs.
	Level 3 Fair Value Measurements
	JCG’s Level 3 recurring fair value measurements largely represent redeemable noncontrolling interests in INTECH Investment Management LLC (“INTECH”) and contingent cash consideration related to the acquisition of VS Holdings Inc., the parent company of VelocityShares, LLC (“VelocityShares”).
	INTECH
Redeemable noncontrolling interests in INTECH are measured at fair value on a quarterly basis or more frequently if events or circumstances indicate that a material change in the fair value of INTECH has occurred. The fair value of INTECH is determined using a relative value methodology that incorporates observable metrics from publicly traded peer companies as valuation comparables, and adjustments related to investment performance and changes in assets under management. The relative value analysis is prepared internally within JCG’s finance organization by personnel with appropriate valuation experience and credentials. In preparing the analysis, JCG benchmarks valuation metrics such as multiples of earnings before interest expense, taxes, depreciation and amortization (“EBITDA”) against current market observables and recent market transactions of a similar size and nature to ensure that the estimates are reasonable. The analysis is reviewed by senior JCG finance personnel and JCG’s Chief Financial Officer. The analysis is also reviewed by the holders of the noncontrolling interests in INTECH. If the valuation is agreed to by both JCG and the holders of noncontrolling interests, JCG uses the analysis to value the redeemable noncontrolling interests.
Significant inputs related to the relative value analysis include INTECH’s trailing 12-month operating results, performance fees, investment performance and trends in assets under management. In addition, market trading comparables from a relevant publicly traded peer set are included to complete the relative valuation process. Publicly available comparables used for the first quarter 2015 valuation analysis ranged from approximately 8.0x to 14.0x EBITDA. Significant increases or decreases in historical INTECH operating results would result in a significantly higher or lower fair value measurement, respectively. Additionally, a significant increase or decrease in market trading comparables would result in a significantly higher or lower fair value measurement, respectively. Generally, any period-over-period change in INTECH performance or level of assets under management in isolation is accompanied by a directionally similar change in the fair value measurement.
VelocityShares
Contingent cash consideration was a component of the purchase price of VelocityShares. The contingent consideration is payable on the first, second, third and fourth anniversaries of the acquisition, in amounts up to $10 million each for the first and second anniversaries, and $8 million each for the third and fourth anniversaries. The payments are contingent on certain VelocityShares’ exchange-traded products reaching defined net revenue targets. The fair value of the contingent cash consideration is calculated on a quarterly basis by forecasting net exchange-traded product revenue, as defined by the purchase agreement, over the contingency period, and determining whether targets are met given forecasted VelocityShares operating results. Forecasted payments are then discounted back to the valuation date. Significant unobservable inputs used in the valuation are limited to forecasted gross revenues and certain expense items which are deducted from these revenues. Increases in forecasted net revenue would increase the fair value of the consideration, subject to payment limitations, while decreases in net revenues would decrease the fair value.
Seeded Investment Products
As of March 31,2015, trading was halted on a single security within the portfolio of a seeded investment product resulting in Level 3 classification.
Nonrecurring Level 3 Fair Value Measurements
Nonrecurring Level 3 fair value measurements include goodwill and intangible assets. JCG measures the fair value of goodwill and intangible assets using a discounted cash flow analysis that requires assumptions regarding projected future earnings and discount rates. Because of the significance of the unobservable inputs in the fair value measurements of these assets and liabilities, such measurements have been classified as Level 3.
The changes in fair value of JCG’s Level 3 items, for the three months ended March 31, 2015 and 2014, are as follows (in millions):
	Three months ended March 31,
	2015							2014

End of period fair value	$	5.3		$	18.1	$	0.2	$	4.8
Transfers Between Fair Value Levels
The underlying securities of mutual funds and separate accounts may be denominated in a foreign currency. In some cases, the closing price of such securities may be adjusted to capture the effects of any post-closing activity affecting the markets in which they trade. Security prices are adjusted based upon historical impacts for similar post-close activity. These adjustments result in the securities being classified as Level 2 and may also result in movements of securities between Level 1 and Level 2.
Additionally, the deconsolidation of a seeded investment product can cause investment securities held by the product to be removed from Level 2. Upon deconsolidation, the entire seeded investment product is valued using the NAV, rather than valued using its underlying securities. Generally, seeded investment products that use the NAV to determine their fair value are classified as Level 1. During the first quarter 2015, the Global Unconstrained Bond Fund in the Company’s international trust was deconsolidated and its $44.3 million of Level 2 assets were reclassified to Level 1.
Transfers are recognized at the end of each reporting period. Transfers from Level 1 and Level 2 classifications for the three months ended March 31, 2015 and 2014, are summarized as follows (in millions):
	March 31,
	2015			2014

	Total long-term debt	$	344.5	$	378.8	$	450.5	$	558.0
	Fair Value of Debt
	The fair value of debt was determined using broker quotes and any recent trading activity for each of the notes listed above, which are considered Level 2 inputs.
	0.750% Convertible Senior Notes due 2018
	The initial conversion rate of the 0.750% Convertible Senior Notes due 2018 (“2018 Convertible Notes”) was 92.06 shares of JCG common stock per $1,000 principal amount of the 2018 Convertible Notes, which is equivalent to an initial conversion price of approximately $10.86 per share of common stock. The initial conversion rate was most recently adjusted during the first quarter 2015 when JCG paid a quarterly cash dividend of $0.08 per share, which was greater than the quarterly dividend of $0.07 per share at the time of issuance. As a result of the quarterly cash dividend paid on February 27, 2015, the conversion rate changed to 92.34 shares of JCG common stock per $1,000 principal amount of 2018 Convertible Notes, equivalent to a conversion price of approximately $10.83 per share of common stock.
	Holders of the 2018 Convertible Notes may convert the notes prior to maturity if the last reported sale price of JCG’s common stock is greater than or equal to $14.08 per share of common stock for at least 20 trading days during a period of 30 trading days. As of March 31, 2015, the 2018 Convertible Notes met the criteria for early conversion and are convertible during the second quarter 2015. The 2018 Convertible Notes conversion criteria are reassessed on a quarterly basis. Fluctuations in the price of JCG’s common stock may cause reclassification of the 2018 Convertible Notes between long-term debt and current portion of long-term debt on a quarter to quarter basis.
	Convertible Note Hedge and Warrants
	In connection with the 2018 Convertible Notes issuance in June 2013, JCG entered into convertible note hedge and warrant transactions which, in combination, are intended to reduce the potential for future dilution to existing shareholders by effectively increasing the initial conversion price of the 2018 Convertible Notes to JCG from $10.86 to $12.60 per share of common stock.
	The initial $10.86 and $12.60 per share of common stock exercise prices of the call options and warrants, respectively, were adjusted during the first quarter 2015 when JCG paid a quarterly cash dividend of $0.08 per share. As a result of the quarterly cash dividend paid on February 27, 2015, which was greater than the quarterly dividend of $0.07 per share at the time of issuance, the exercise price of the call options changed to $10.83 per share of common stock and the exercise price of the warrants changed to $12.56 per share of common stock.
	Interest Rate Adjustment Covenant
	The 6.700% Senior Notes due 2017 (“2017 Senior Notes”) are subject to 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 Investor Services Inc. (“Moody’s”) from Baa3 or by Standard and Poor’s Rating Service (“S&P”) from BBB-, up to a maximum increase of 200 basis points. If the interest rate has been adjusted upward as a result of either Moody’s or S&P decreasing its rating, then for each level of a subsequent rating increase, 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 issuance of the respective notes. The interest rate adjustment covenant will permanently terminate if the Company’s debt ratings increase to Baa2 (or higher) by Moody’s and BBB (or higher) by S&P, with a stable or positive outlook regardless of any subsequent decrease in the ratings by either or both rating agencies. On February 26, 2015, Moody’s reaffirmed JCG’s credit rating of Baa3, with a stable outlook. On March 20, 2015, S&P reaffirmed JCG’s credit rating of BBB-, and revised its outlook to positive from negative.
	Credit Facility
	At March 31, 2015, JCG had a $200 million, unsecured, revolving credit facility (“Credit Facility”) with JPMorgan Chase Bank, N.A., as administrative agent and swingline lender. The Credit Facility can be used by JCG and its subsidiaries for working capital needs and general corporate purposes. The Credit Facility bears interest on borrowings outstanding at the London Interbank Offered Rate (“LIBOR”) plus a spread, which is based on JCG’s credit rating. JCG is required to pay a quarterly commitment fee on any unused portion of the Credit Facility, which is also based on JCG’s credit rating. Under the Credit Facility, the financing leverage ratio cannot exceed 3.00x, and the interest coverage ratio must equal or exceed 4.00x. At March 31, 2015, JCG was in compliance with all covenants, and there were no borrowings under the Credit Facility at March 31, 2015, or during the three months ended March 31, 2015. The Credit Facility has a maturity date of November 23, 2018.

	Consolidated Seeded Investment Products
	Redeemable noncontrolling interests in consolidated seeded investment products may fluctuate from period to period, and are impacted by changes in JCG’s relative ownership percentage of seeded products, changes in the amount of third party investment in seeded products, and volatility in the market value of the seeded products’ underlying securities. Third party redemption of investments in consolidated seeded products are redeemed from the respective product’s net assets, and cannot be redeemed from the assets of other seeded products or from the assets of JCG.
