	Derivative Instruments
	The Company maintains an economic hedge program that uses derivative instruments to hedge against market volatility of its 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, 2014, and December 31, 2013:
		March 31, 2014					December 31, 2013
		Number of		Notional value			Number of		Notional value
		contracts		(in millions)			contracts		(in millions)
	Index swaps	5		$	113.6		6		$	184.3
	Index futures	7		$	90.9		6		$	66.6
	Foreign currency forward contracts	4		$	35.9		6		$	93.6
	These instruments are not designated as hedges for accounting purposes. Changes in fair value of the index swaps and index futures are recognized in investment (losses) gains, net on JCG’s Condensed Consolidated Statements of Comprehensive Income while changes in the fair value of the foreign currency forward contracts are recognized in other income, net on JCG’s Condensed Consolidated Statements of Comprehensive Income.
	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 pledged $2.7 million and $4.8 million in cash collateral with the counterparty of the index futures as of March 31, 2014 and December 31, 2013, respectively. The cash collateral is included in other current assets on JCG’s Condensed Consolidated Balance Sheets.

	JCG’s Level 1 fair value measurements consist of trading securities and available-for-sale securities with quoted market prices in active markets. The majority of investment securities classified as Level 2 are debt securities with values derived from evaluated pricing by independent third-party providers. Short-term securities with maturities of 60 days or less are valued at amortized cost, which approximates market value, and are also categorized as Level 2 in the hierarchy. 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 impacting 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.
	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, 2014 and 2013, are summarized as follows (in millions):

	JCG’s Level 3 recurring fair value measurements represent redeemable noncontrolling interests in INTECH Investment Management LLC (“INTECH”).
	Redeemable noncontrolling interests in INTECH are measured at fair value on an annual 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 discounted cash flow methodology with probability-weighted scenarios. Discounted cash flow analyses are prepared internally within JCG’s finance organization by personnel with appropriate valuation experience and credentials. In preparing the analyses, JCG benchmarks valuation metrics such as multiples of earnings against recent market transactions of a similar size and nature to ensure that the estimates are reasonable. The analyses are reviewed by senior JCG finance personnel and JCG’s Chief Financial Officer. The analyses are 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 utilizes the analyses to value the redeemable noncontrolling interests. If the holders of noncontrolling interests object to the analyses, a valuation is obtained from a third-party investment bank agreed upon by the interested parties. JCG has engaged a third-party investment bank for such valuation in the past and may do so again in the future.
	Significant unobservable inputs related to the INTECH discounted cash flow analysis include forecasted operating results, discount rate and terminal multiple of forecasted earnings before interest expense, taxes, depreciation and amortization. Significant increases or decreases in the forecasted operating results and terminal multiple inputs in isolation would result in a significantly higher or lower fair value measurement, respectively. A significant increase or decrease in the discount rate input would result in a significantly lower or higher fair value measurement, respectively. The terminal multiple input for each scenario is influenced by the growth rate contained in the forecasted operating results. Generally, a change in the assumptions used for forecasted operating results is accompanied by a directionally similar change in the terminal multiple.
	Nonrecurring Level 3 fair value measurements included 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 recurring Level 3 fair value measurements for the three months ended March 31, 2014 and 2013, are as follows (in millions):

	Fair Value of Debt
	The fair value of debt was determined using broker quotes and recent trading activity for each of the notes listed above, which are considered Level 2 inputs.
	6.119% Senior Notes due 2014
	On April 15, 2014, the 6.119% Senior Notes due 2014 matured and JCG paid the principal balance of $38.9 million.
	Interest Rate Adjustment Covenant
	The 6.119% Senior Notes due 2014 and 6.700% Senior Notes due 2017 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 & 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 March 18, 2014, S&P reaffirmed JCG’s credit rating of BBB-, with a negative outlook and Moody’s reaffirmed JCG’s credit rating of Baa3, with a stable outlook.
	Credit Facility
	At March 31, 2014, JCG had a $200 million, unsecured, revolving credit facility (“the Credit Facility”) with JPMorgan Chase Bank, N.A., as administrative agent and swingline lender. Under the Credit Facility, JCG’s financing leverage ratio cannot exceed 3.00x, and its interest coverage ratio must equal or exceed 4.00x. At March 31, 2014, JCG was in compliance with all covenants and there were no borrowings under the Credit Facility. The Credit Facility has a maturity date of November 23, 2018.
	Capital Lease Obligations
	JCG’s capital lease obligations represent leased computer equipment. The carrying values of the obligations totaled $1.5 million and $1.8 million at March 31, 2014, and December 31, 2013, respectively, and are included in other accrued liabilities and other liabilities on JCG’s Condensed Consolidated Balance Sheets.

	JCG’s provision for income taxes was $25.9 million and $20.2 million, or 45.4% and 40.5% of income before taxes, for the three months ended March 31, 2014 and 2013, respectively. The Company’s effective tax rate for the three month period ending March 31, 2014 increased by 4.9% due largely to the reversal of unrealized deferred tax assets upon the expiration and vesting of certain equity-based compensation awards.
	As of March 31, 2014, JCG had $5.8 million of accrued reserves for income tax contingencies. JCG accrued additional reserves for income tax contingencies in the amount of $0.2 million during the first quarter 2014, creating a net tax expense of $0.1 million. JCG anticipates that its income tax contingency reserves will decrease by approximately $1.6 million in the next 12 months, primarily from the expiration of statutes of limitations and the resolution of audits. Accrued reserves for income tax contingencies are presented in other accrued liabilities and other liabilities on JCG’s Condensed Consolidated Balance Sheets.

	Perkins
	On February 3, 2014, JCG exercised its right to purchase the remaining noncontrolling ownership units in Perkins Investment Management LLC (“Perkins”) of 0.4%. Under the terms of the call, the remaining noncontrolling ownership units were redeemed for $0.6 million on March 14, 2014, based on the fair value as of the call exercise date. The fair value of the ownership units was based on a contractual formula driven by revenue and investment performance of products managed by Perkins.
	The noncontrolling interests were primarily held by founding members who are not involved in the management of Perkins. Perkins management continues to hold the majority of their interests in Perkins through senior profits interests awards and long-term incentive compensation plans. The Perkins senior profits interests awards and long-term incentive compensation plans provide active members of Perkins management an ongoing stake in the success of Perkins.
