DESCRIPTION OF THE BUSINESS	'
DESCRIPTION OF THE BUSINESS	'
	NOTE 1 — DESCRIPTION OF THE BUSINESS
	Janus Capital Group Inc. and its subsidiaries (collectively, "JCG" or the "Company") derive revenue from providing investment management, administration, distribution and related services to financial advisors, individuals and institutional investors through mutual funds, other pooled investment vehicles, separate accounts and subadvised relationships (collectively referred to as "investment products") in both domestic and international markets. 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. Certain investment products are also subject to performance fees which vary based on a product's 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 domestic and international 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 JCG's operating results. A significant portion of JCG's revenue is derived from contracts to manage mutual funds, which are subject to annual review and approval by each fund's Board of Trustees or its shareholders, or both.
	JCG's significant subsidiaries at December 31, 2013, include:
	•
	Janus Capital Management LLC ("Janus"), (wholly-owned subsidiary) — Janus offers growth and core equity, global and international equity as well as balanced and fixed income investment products.
	•
	INTECH Investment Management LLC ("INTECH"), (96.8% owned subsidiary) — INTECH offers risk-managed investment products that are based on a mathematical theorem which seeks to add value for clients by capitalizing on the volatility in stock price movements. INTECH's goal is to achieve long-term returns that outperform a specified benchmark index, while controlling risks and trading costs. INTECH manages and subadvises institutional and separate accounts and subadvises certain Janus mutual funds.
	•
	Perkins Investment Management LLC ("Perkins"), (99.6% owned subsidiary) — Perkins offers value-disciplined investment products, including small, mid and large cap and global value investment products. On February 3, 2014, JCG exercised its right to purchase the remaining 0.4% of Perkins. See Note 10 — Noncontrolling Interests for further discussion regarding the purchase of the remaining noncontrolling interest in Perkins.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	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 in consolidation. Events subsequent to the balance sheet date have been evaluated for inclusion in the accompanying financial statements through the issuance date.
	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 and the differences could be material. JCG's significant estimates relate to investment securities, goodwill and intangible assets, equity compensation and income taxes.
	Segment Information
	The Company operates one business segment, its Investment Management operations.
	Cash Equivalents
	Short-term investments with an initial maturity of three months or less when purchased, including investments in money market funds, are considered cash equivalents.
	Property and Equipment
	Property and equipment is recorded at cost. Depreciation and amortization are 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 $11.2 million, $13.4 million and $14.0 million for the years ended December 31, 2013, 2012 and 2011, respectively. Property and equipment is summarized as follows (in millions):
				December 31,
		Depreciation and
		amortization
		period		2013			2012
	Furniture, fixtures, computer equipment and software	3-7 years		$	199.3		$	191.9
	Leasehold improvements	3-24 years			37.5			37.1
	Subtotal				236.8			229
	Less accumulated depreciation and amortization				(206.9	)		(195.7	)
	Property and equipment, net			$	29.9		$	33.3
	JCG 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 in an amount equal to the excess of the carrying amount of the asset over the fair value of the asset. There were no impairments of long-lived assets for the years ended December 31, 2013, 2012 and 2011.
	Purchased software is recorded at cost and amortized over its estimated useful life. Internal and external costs incurred in connection with developing or obtaining software for internal use are expensed as incurred during the preliminary project stage, as are training and maintenance costs. Internal and external costs incurred for internal use software during the application development stage are capitalized until such time that the software is substantially complete and ready for its intended use. Application development stage costs are amortized on a straight-line basis over the estimated useful life of the software.
	Capitalized software costs totaled $8.3 million and $7.9 million at December 31, 2013 and 2012, respectively, and are presented within property and equipment, net on the Consolidated Balance Sheets.
	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 redemptions reduce the unamortized deferred commissions balance. Amortization expense for the years ended December 31, 2013, 2012 and 2011, totaled $5.3 million, $5.6 million and $7.4 million, respectively.
	Deferred commissions, which are recorded as components of other current assets and non-current assets on the Consolidated Balance Sheets, are summarized as follows (in millions):
		December 31,
		2013			2012
	Deferred commissions — current	$	2.2		$	3
	Deferred commissions — non-current		0.3			0.4
	Total	$	2.5		$	3.4
	Investment Securities
	JCG classifies investment 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 on JCG's Consolidated Balance Sheets at fair value and consist primarily of investments related to seeded investment products, investments in advised funds previously utilized for the economic hedging of mutual fund share awards and investments related to the economic hedging of deferred compensation.
	Seeded Investment Products
	JCG periodically adds new investment strategies to its investment product offerings by providing the initial cash investment or "seeding." The primary purpose of seeded investment products is to generate an investment performance track record in a product to attract third-party investors. JCG's initial investment in a new product represents 100% ownership in that product. Seeded investment products are initially consolidated and the individual securities within the portfolio are accounted for as trading securities. JCG consolidates such investment products as long as it holds a controlling interest in the investment product, defined as greater than 50% ownership.
	Upon deconsolidation, JCG continues to account for its investments in seeded products as trading securities if its ownership is between 20% and 50%. JCG may redeem invested seed capital for a variety of reasons, including when third-party investments in the relevant product are sufficient to sustain the given investment strategy. The length of time JCG holds a majority interest in a product varies based on a number of factors including, but not limited to, market demand, market conditions and investment performance. Changes in fair value of securities classified as trading are recognized in investment gains (losses), net on JCG's Consolidated Statements of Comprehensive Income.
	The Company has determined that its seeded investment products do not represent variable interest entities. Seed investments are made largely in mutual funds, but may also be made in commingled pools and separate accounts. JCG has determined mutual funds to be voting interest entities rather than variable interest entities. Commingled pools are established as limited liability companies or partnerships, and as such, the Company applies partnership accounting rules. These rules dictate that a managing member or general partner would not consolidate an entity if the members or limited partners carry substantive kick-out rights. All of the Company's commingled pools carry substantive kick-out rights. Seed investments in separate accounts are 100% owned by JCG and are accounted for as trading securities.
	Economic Hedging of Mutual Fund Share Awards and Deferred Compensation
	JCG grants mutual fund share awards to employees that are indexed to certain funds managed by JCG. Upon vesting, participants receive the value of the mutual fund share awards adjusted for gains or losses attributable to the mutual funds to which the award was indexed, subject to tax withholding. Historically, JCG made corresponding investments in JCG managed funds for purposes of economically hedging the mutual fund share awards. Effective January 2013, such corresponding investments are no longer made. The value of the investments in the JCG managed funds is a component of investment securities on JCG's Consolidated Balance Sheets.
	The Company maintains deferred compensation plans for certain highly compensated employees and members of its Board of Directors. 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 and its subsidiaries. The Company makes no contributions to the plan. To protect against market variability of the liability, the Company creates an economic hedge by investing in mutual funds that are consistent with the deferred amounts and mutual fund elections of the participants. Such investments remain assets of JCG. Changes in market value of the liability to participants are recognized as long-term incentive compensation in JCG's Consolidated Statements of Comprehensive Income and changes in the market value of the mutual fund securities are recognized in investment gains (losses), net on JCG's Consolidated Statements of Comprehensive Income.
	Available-for-Sale Securities
	Investment securities classified as available-for-sale consist of seeded investment products in which JCG holds a less than 20% interest and are carried on JCG's Consolidated Balance Sheets at fair value, and debt securities. The debt securities are classified as available-for-sale as JCG may not hold them to maturity. Changes in fair value are reflected as a component of other comprehensive (loss) income, net of tax on JCG's Consolidated Statements of 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 (losses), net on JCG's Consolidated Statements of Comprehensive Income. Accumulated gains and losses are reclassified to earnings when the securities are sold on a first-in, first-out cost basis.
	Held-to-Maturity Securities
	Investment securities are classified as held-to-maturity when JCG has the intent and ability to hold the securities to maturity. Held-to-maturity securities are carried on JCG's Consolidated Balance Sheets at cost with corresponding interest income reflected as other income, net on JCG's Consolidated Statements of Comprehensive 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 (losses), net on JCG's Consolidated Statements of Comprehensive Income. There were no held-to-maturity securities on JCG's Consolidated Balance Sheets for the years ended December 31, 2013 and 2012.
	Impairment Evaluation
	JCG 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, JCG considers the duration, extent and circumstances of any decline in fair value.
	For debt securities, an other-than-temporary impairment ("OTTI") is evident if JCG intends to sell the debt security or will more likely than not be required to sell the debt security before full recovery of the entire amortized cost basis is realized. However, even if JCG does not intend to sell the debt security and will not likely be required to sell the debt security before recovery of its entire amortized cost basis, JCG must evaluate expected cash flows to be received and determine if a credit loss has occurred. In the event of a credit loss, the credit component of the impairment is recognized within investment gains (losses) on JCG's Consolidated Statements of Comprehensive Income and the noncredit component is recognized through other comprehensive (loss) income, net of tax on JCG's Consolidated Statements of Comprehensive Income.
	For equity securities, JCG evaluates the securities in an unrealized loss position in the available-for-sale portfolio for OTTI on the basis of the duration of the decline in value of the security and severity of that decline as well as JCG's intent and ability to hold these securities for a period of time sufficient to allow for any anticipated recovery in the market value. If it is determined that the impairment on an equity security is other than temporary, an impairment loss equal to the difference between the carrying value of the security and its fair value is recognized within investment gains (losses) on JCG's Consolidated Statements of Comprehensive Income. There were no impairments of investment securities for the years ended December 31, 2013, 2012 and 2011.
	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, futures contracts and forward contracts, respectively. These derivative instruments are not classified as hedges for accounting purposes. The Company records all derivatives as either assets or liabilities on JCG's Consolidated Balance Sheets and measures those investments at fair value. Changes in the value of the index swaps and futures contracts are recognized as a component of investment gains (losses), net on JCG's Consolidated Statements of Comprehensive Income. Changes in the value of the foreign currency forward contracts are recognized as a component of other income, net on JCG's Consolidated Statements of Comprehensive Income.
	Fair Value Measurements
	Fair value of assets and liabilities is determined using observable market data based on recent trading activity. Where observable market data is unavailable due to a lack of trading activity, JCG utilizes internally developed models to estimate fair value and independent third parties to validate assumptions, when appropriate. 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 JCG is valuing and the selected benchmark. Depending on the type of securities owned by JCG, other valuation methodologies may be required.
	Measurements of fair value are classified within a hierarchy based upon the transparency of inputs used in the valuation of an asset or liability. Classification within the hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
	The valuation hierarchy contains three levels:
	•
	Level 1 — Valuation inputs are unadjusted quoted market prices for identical assets or liabilities in active markets.
	•
	Level 2 — Valuation inputs are quoted market prices for identical assets or liabilities in markets that are not active, quoted market prices for similar assets and liabilities in active markets, and other observable inputs directly or indirectly related to the asset or liability being measured.
	•
	Level 3 — Valuation inputs are unobservable and significant to the fair value measurement.
	JCG's Level 1 and Level 2 fair value measurements consist of debt securities with maturities of 90 days or less carried within cash and cash equivalents, exchange-traded equity and debt securities underlying separate accounts and consolidated mutual funds and shares of unconsolidated mutual funds, investments in mutual funds related to the economic hedging of mutual fund share awards and deferred compensation plans, derivative instruments and long-term debt. The fair value level of consolidated seeded investment products is determined by the underlying securities of the product while the fair value level of equity-method and unconsolidated seeded investment products are valued using the respective net asset value ("NAV") of each product. All seeded investment products that utilize 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%.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 and are traded on exchanges outside of the U.S. 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. 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.
	JCG's Level 3 recurring fair value measurements primarily represent redeemable noncontrolling interests. Redeemable noncontrolling interests in INTECH are measured at fair value using a discounted cash flow methodology. Significant inputs to the discounted cash flow analysis include forecasted operating results, discount rate and terminal multiple of future cash flows. Redeemable noncontrolling interests in Perkins are measured by a contractual formula intended to represent fair value. See Note 6 — Fair Value Measurements for further discussion of the fair value of redeemable noncontrolling interests.
	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.
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. The effect of changes in tax rates on deferred tax assets and liabilities is recognized in the period that includes the enactment date. Significant management judgment is required in developing JCG's provision for income taxes, including the valuation allowances that might be required against deferred tax assets and the evaluation of various income tax contingencies.
The accounting guidance for uncertainty in income taxes 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. The tax contingencies liability relates primarily to general state tax items and has been recorded in other liabilities and other accrued liabilities on JCG's Consolidated Balance Sheets, as appropriate.
Taxing authorities generally charge interest and may assess penalties in the event that a tax position taken is subsequently reversed upon examination. JCG 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, 2013, 2012 and 2011, $1.3 million, $2.2 million and $3.4 million, respectively, 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. JCG 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. JCG records interest income from taxing authorities as a component of the income tax provision.
Goodwill and Intangible Assets, Net
Goodwill represents the excess of cost over the fair value of the identifiable net assets of acquired companies. JCG's identifiable intangible assets generally represent the cost of client relationships and mutual fund advisory contracts acquired as well as brand name and trademark. Goodwill and indefinite-lived intangible assets are tested for impairment annually as of October 1 or more frequently if events or circumstances indicate that the carrying value may not be recoverable. Intangible assets subject to amortization are tested for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. 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.
Noncontrolling Interests and Redeemable Noncontrolling Interests
Noncontrolling interests that are not subject to redemption rights are classified in permanent equity. Redeemable noncontrolling interests are classified outside of permanent equity on the Consolidated Balance Sheets and are measured at estimated fair value as of the balance sheet dates. Changes in fair value of redeemable noncontrolling interests are recognized as increases or decreases to redeemable noncontrolling interests with an offsetting charge to retained earnings. Certain of the INTECH and Perkins ownership interests granted to employees become subject to redemption rights upon vesting at which time such interests are reclassified to redeemable noncontrolling interests. Earnings attributable to noncontrolling interests that are and are not subject to redemption rights are combined in JCG's Consolidated Statements of Comprehensive Income. Acquisitions of entities in which JCG holds an existing controlling interest are treated as a reduction of noncontrolling interests or redeemable noncontrolling interests in an amount equal to the purchase price. See Note 10 — Noncontrolling Interests for further discussion of noncontrolling interests.
Revenue Recognition
Investment management and shareowner servicing fees are recognized as services are provided. These revenues are generally determined in accordance with contracts based upon a percentage of average assets under management.
Performance fee revenue is derived from certain mutual funds and separate accounts. Mutual fund performance fees represent an adjustment to the investment management fee of certain mutual funds and are based on the relative investment performance of each fund compared to a specific benchmark index. The adjustment is up to a positive or negative 15 basis points and is calculated using each fund's daily net average assets based on a trailing 36-month measurement period. Separate 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. Separate account performance fees are recognized at the end of the contractual period if the stated performance criteria are achieved.
Marketing
Marketing and promotional costs are generally 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 and consists 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 market price on date of grant. The Black-Scholes model requires management to estimate certain variables, including the lives of options from grant date to exercise date, the volatility of the underlying shares and future dividend rates.
JCG estimates, at the time of grant, the amount of awards that are not expected to vest based on historical forfeiture rates and subsequently records adjustments, as appropriate.

RECENT ACCOUNTING PRONOUNCEMENTS	'
	NOTE 3 — RECENT ACCOUNTING PRONOUNCEMENTS
	In January 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-01, "Balance Sheet: Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities." This ASU amends ASU 2011-11, "Balance Sheet: Disclosures about Offsetting Assets and Liabilities" to clarify that the scope applies to derivatives, repurchase and reverse repurchase agreements, and securities borrowing and lending transactions that are either offset in accordance with applicable accounting guidance or subject to master netting or similar arrangements. Other types of financial assets and liabilities subject to master netting or similar arrangements are not subject to the disclosure requirements in ASU 2011-11. The amendments were effective for fiscal years beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of this ASU did not have a material impact on JCG's consolidated financial statements; however, there is an impact related to the notes to the financial statements upon adoption in 2013.
	In February 2013, the FASB issued ASU No. 2013-02, "Comprehensive Income: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." The ASU requires an entity to disclose changes in accumulated other comprehensive income ("OCI") balances by component and disaggregate the total change between current period OCI and reclassification adjustments. For significant reclassifications out of accumulated OCI, an entity is required to identify each line item affected by the reclassification in the notes to the financial statements or on the statement where net income is presented. The ASU is effective for JCG's fiscal period beginning January 1, 2013. JCG adopted ASU No. 2013-02 on January 1, 2013, and added related disclosure in Note 13 — Accumulated Other Comprehensive (Loss) Income.
	In July 2012, the FASB issued an update to the accounting guidance related to the testing of indefinite-lived intangible assets for impairment. Under the amended guidance, a reporting entity may elect to assess qualitative factors to determine if it is more likely than not that the fair value of the intangible asset is less than its carrying amount as a basis for determining whether it is necessary to perform the currently required quantitative fair value assessment. The revised standard is effective for annual and interim indefinite-lived intangible asset impairment tests performed for the Company's fiscal year beginning January 1, 2013. The Company did not elect the qualitative method for testing its indefinite-lived intangible assets for impairment testing during 2013.

	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, futures contracts and foreign currency forward contracts, respectively. As of December 31, 2013, JCG had six index swap positions with a notional value of $184.3 million, six futures contract positions with a notional value of $66.6 million and six foreign currency forward contract positions with a notional value of $93.6 million.
	These instruments are not designated as hedges for accounting purposes. Changes in fair value of the index swaps and futures contracts are recognized in investment gains (losses), net on the Consolidated Statements of Comprehensive Income while changes in fair value of the foreign currency forward contracts are recognized in other income, net on the Consolidated Statements of Comprehensive Income.
	Index swaps and foreign currency forward contracts are subject to a master netting agreement and their fair values are netted against associated cash collateral within cash and cash equivalents and other current assets on the Consolidated Balance Sheets. Futures contracts are subject to a separate master netting agreement with their fair values netted against their associated cash collateral amount within other current assets on the Consolidated Balance Sheets.

	Goodwill	$	488.2		$	—		$	488.2
	The majority of goodwill and intangible assets were generated from the purchase of the noncontrolling interest of Janus and acquisitions of interests in INTECH and Perkins. Intangible assets acquired as a result of these transactions include brand name and trademark, mutual fund advisory contracts and client relationships.
	Indefinite-lived intangible assets represent brand name, trademark and mutual fund advisory contracts.
	Definite-lived intangible assets represent client relationships, which are amortized over their estimated lives of 12 years using the straight-line method. JCG recognizes an impairment charge equal to the unamortized value of the associated subadvised relationship when notification of termination is received. There were no intangible asset impairment charges recognized during the years ended December 31, 2013 and 2011. During the year ended December 31, 2012, the Company recognized $7.7 million of intangible asset impairment charges in amortization expense from the loss of JCG subadvised relationships.
	Amortization expense was $12.2 million, $19.5 million and $11.9 million for the years ended December 31, 2013, 2012 and 2011, respectively. Future amortization expense is expected to be $9.6 million in 2014, $7.7 million in 2015, $7.6 million in 2016, $7.6 million in 2017, $5.0 million in 2018 and $3.4 million thereafter.
	Impairment Testing
	The October 2013 tests of goodwill and indefinite-lived intangible assets indicated that estimated fair values substantially exceeded their respective carrying values, and as such, no impairment charges were recognized. The October 2013 tests included certain underlying key assumptions regarding future overall market trends and Company operating performance. If actual future market results and Company operating performance vary significantly and unfavorably to those included in the Company's financial forecast, the Company may be subject to impairment charges related to its goodwill and indefinite-lived intangible assets.
	No impairment charges were recognized as a result of the October 2012 and 2011 tests of goodwill and indefinite-lived intangible assets.

	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 from Level 1 and Level 2 classifications for the years ended December 31, 2013 and 2012, are summarized as follows (in millions):
		December 31,
		2013			2012
	Transfers from Level 1 to Level 2	$	—		$	15.1
	Transfers from Level 2 to Level 1	$	12.7		$	0.3
	An adjustment to foreign securities for subsequent fluctuations in active markets was not necessary at December 31, 2013, resulting in transfers from Level 2 to Level 1. Transfers are recognized at the end of each reporting period.
	JCG's Level 3 recurring fair value measurements primarily represent redeemable noncontrolling interests in INTECH and Perkins.
	Redeemable noncontrolling interests in INTECH are measured at fair value on an annual basis, or more frequently if events or circumstances indicate that 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.
	Redeemable noncontrolling interests in Perkins are measured by a contractual formula intended to represent fair value on a monthly basis. The contractual formula is prepared internally within JCG's finance organization and is 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 Perkins. In the event either party objects to the valuation determined by the contractual formula, a valuation is obtained from a third-party investment bank agreed upon by the interested parties. JCG has not engaged a third-party investment bank for such valuation in the past but may do so in the future.
	Inputs to the Perkins contractual formula include trailing 12-month revenues of Perkins investment products and the relative performance of Perkins investment products as compared to benchmark indices. The contractual formula applies defined revenue multiples to trailing 12-month Perkins revenues to arrive at fair value; the revenue multiples are subject to increases if certain performance targets are met. Due to the contractual nature of the formula, the revenue and performance inputs are relationally independent. The revenue multiples used in the December 31, 2013 and 2012 valuations were 3.38x and 3.43x, respectively.
	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 recurring Level 3 fair value measurements for the years ended December 31, 2013 and 2012, 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.
	Partial Buyback of 6.700% Senior Notes and Loss on Early Extinguishment of Debt
	On August 30, 2013, JCG repurchased on the open market $8.0 million aggregate principal amount of the Company's outstanding 6.70% Senior Notes due 2017 ("2017 Senior Notes") for $8.9 million in cash. JCG recognized a loss of $0.9 million on the repurchase.
	Exchange of Convertible Senior Notes and Loss on Early Extinguishment of Debt
	On June 14, 2013, JCG entered into separate, privately negotiated exchange agreements pursuant to which $110.0 million aggregate principal amount of JCG's existing 3.25% Convertible Senior Notes due 2014 ("2014 Convertible Notes") was exchanged for $116.6 million aggregate principal amount of newly-issued 0.75% Convertible Senior Notes due 2018 ("2018 Convertible Notes"). Immediately following the exchange, $60.0 million aggregate principal amount of existing 2014 Convertible Notes remained outstanding.
	The non-cash exchange of the 2018 Convertible Notes for a portion of the 2014 Convertible Notes constituted an extinguishment of debt under applicable accounting guidance. As a result of the extinguishment, JCG recognized a $12.6 million loss on early extinguishment of debt related to the settlement of the liability component of the exchanged 2014 Convertible Notes, and a $2.0 million reduction in equity related to the retirement of the conversion feature of the exchanged 2014 Convertible Notes.
	0.750% Convertible Senior Notes
	The 2018 Convertible Notes pay interest semiannually at a rate of 0.75% per annum on January 15 and July 15 of each year, beginning on January 15, 2014, and will be convertible, under certain circumstances, into cash, shares of JCG common stock or a combination of cash and shares of JCG common stock, at the Company's election. The initial conversion rate of the 2018 Convertible Notes is 92.1 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, subject to adjustment in certain circumstances. This initial conversion price represents a premium of 25% relative to the $8.69 per share closing price of JCG's common stock on June 13, 2013, the date of pricing.
	Holders may convert their 2018 Convertible Notes at their option prior to the close of business on the business day immediately preceding April 15, 2018, only under the following circumstances: (1) during any calendar quarter commencing after September 30, 2013, if the last reported sale price of JCG's common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the 2018 Convertible Notes for each day of such period is less than 98% of the product of the last reported sale price of JCG's common stock and the applicable conversion rate; or (3) upon the occurrence of specified corporate events. On or after April 15, 2018, until maturity, holders may convert their notes regardless of the preceding circumstances.
	Because the 2018 Convertible Notes may be wholly or partially settled in cash, the liability and conversion feature components are required to be accounted for separately. The initial $102.0 million liability component was determined by discounting future contractual cash flows at a 3.5% rate, which is consistent with the estimated market interest rate for similar senior notes with no conversion option. The liability component will accrete up to the face value of $116.6 million over the five-year expected term of the 2018 Convertible Notes through interest expense. The $14.6 million initial equity component was determined as the difference between the initial liability component and the face value of the 2018 Convertible Notes and was recorded as an adjustment to equity.
	The 2018 Convertible Notes include an unamortized discount at December 31, 2013, of $13.3 million, which will be amortized over the remaining term. Interest expense related to the 2018 Convertible Notes includes interest on the outstanding principal balance as well as amortization of capitalized issuance costs and totaled $2.1 million for the year ended December 31, 2013.
	Convertible Note Hedge and Warrant Transactions
	In connection with the 2018 Convertible Notes issuance, 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 conversion price of the 2018 Convertible Notes to JCG from $10.86 to $12.60 per share of common stock.
	The convertible note hedge and warrant transactions consist of two separate instruments: purchased call options and the sale of warrants. The call options represent the same number of shares of JCG's common stock underlying the 2018 Convertible Notes with a strike price of $10.86 per share of common stock, which is equal to the conversion price of the 2018 Convertible Notes. The call options cost $16.1 million. To offset the cost of the call options, JCG sold warrants to the counterparty of the call options for the same number of shares of JCG's common stock underlying the 2018 Convertible Notes with an exercise price of $12.60 per share of common stock. The proceeds from the sale of the warrants totaled $10.5 million. The call options and warrants may be settled in cash or stock at JCG's election and are indexed to JCG's equity. Accordingly, the Company recorded the $5.6 million net cost of the instruments as a reduction in equity and will not recognize subsequent changes in fair value of these financial instruments in its consolidated financial statements.
	Loss on Early Extinguishment of Debt
	On March 20, 2012, JCG completed a debt tender in which $59.4 million aggregate principal amount of the Company's outstanding 6.119% Senior Notes due 2014 ("2014 Senior Notes") and 2017 Senior Notes was repurchased with cash on hand. JCG recognized a $7.2 million loss on early extinguishment of debt related to the repurchase of these notes.
	During the fourth quarter 2010, JCG exercised its redemption right on the $120.9 million carrying value of its 6.250% Senior Notes and retired the notes on January 14, 2011. Under the terms of the redemption, JCG was required to pay the principal and the present value of the interest that would have been paid if the debt remained outstanding through scheduled maturity. As a result, JCG recognized a $9.9 million loss on early extinguishment of debt in the first quarter 2011.
	3.250% Convertible Senior Notes Due 2014
	In July 2009, JCG issued $170.0 million of 2014 Convertible Notes, which pay interest at 3.25% semiannually on July 15 and January 15 of each year and mature on July 15, 2014, unless earlier converted. As discussed above, $110.0 million aggregate principal amount of the 2014 Convertible Notes was exchanged for the 2018 Convertible Notes, leaving $60.0 million aggregate principal amount of 2014 Convertible Notes outstanding. The 2014 Convertible Notes are convertible under certain circumstances into cash, shares of JCG common stock or a combination of cash and shares of JCG common stock, at JCG's election. The holders of the 2014 Convertible Notes have the right to require JCG to repurchase their notes for cash under certain circumstances. The original conversion rate of 71.3 shares of JCG common stock per $1,000 principal amount of 2014 Convertible Notes was most recently adjusted during the fourth quarter 2013 when JCG paid a quarterly cash dividend of $0.07 per share. As a result of the quarterly cash dividend paid on November 22, 2013, the conversion rate changed to 75.9 shares of JCG common stock per $1,000 principal amount of 2014 Convertible Notes, equivalent to a conversion price of approximately $13.17 per share of common stock. JCG is required to continue to adjust the conversion rate to the extent there are future dividend payments above $0.04 per share on an annual basis. The 2014 Convertible Notes are not callable by JCG. During the second quarter 2013, JCG derecognized $7.4 million and $0.6 million of unamortized debt discount and capitalized issuance costs, respectively, in conjunction with the exchange of $110.0 million aggregate principal amount of the 2014 Convertible Notes discussed above.
	The 2014 Convertible Notes include an unamortized discount at December 31, 2013 and 2012, of $2.1 million and $16.0 million, respectively. The $2.1 million balance at December 31, 2013, will be amortized over the remaining term. Interest expense related to the 2014 Convertible Notes includes interest on the outstanding principal balance as well as amortization of capitalized issuance costs and totaled $10.7 million, $15.5 million and $14.7 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	Holders may convert their notes at their option prior to the close of business on the business day immediately preceding April 15, 2014, only under the following circumstances: (1) during any calendar quarter commencing after September 30, 2009, if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day; or (2) upon the occurrence of other specified events. On or after April 15, 2014, until maturity, holders may convert their notes regardless of the preceding circumstances. As of December 31, 2013, the conversion criteria of the 2014 Convertible Notes have not been satisfied.
	Because the 2014 Convertible Notes may be wholly or partially settled in cash, the liability and conversion feature components are required to be accounted for separately. The $125.7 million initial debt component was determined by discounting future contractual cash flows at a 10.0% rate, which is consistent with the estimated market rate at the time of issuance for similar senior notes with no conversion option. The debt component will accrete up to the face value over the five-year expected term through interest expense. The $44.3 million (or $27.9 million, net of deferred taxes) initial equity component was determined using the difference between the proceeds and the debt component. The fair value of the 2014 Convertible Notes in the above table is based on the outstanding principal balance, while the carrying value represents the outstanding principal balance exclusive of the unamortized discounts.
	Change of Control and Rating Downgrade Covenant
	If the Company experiences a change of control, and in connection therewith, the 2017 Senior Notes become rated below investment grade by Standard & Poor's ("S&P") Rating Service and Moody's Investors Service, Inc. ("Moody's"), JCG must offer to repurchase the 2017 Senior Notes at a price equal to 101% of the principal amount plus accrued and unpaid interest to the repurchase date.
	Interest Rate Adjustment Covenant
	The 2014 Senior Notes and 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 from Baa3 or by 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. S&P increased JCG's credit rating to BBB- on January 10, 2011, resulting in a 25 basis point decrease in the interest rates payable on the 2014 Senior Notes and 2017 Senior Notes. On January 9, 2013, S&P reaffirmed JCG's credit rating of BBB- and revised its outlook from stable to negative. On May 17, 2013, Moody's reaffirmed JCG's credit rating of Baa3, with a stable outlook.
	Credit Facility
	At December 31, 2013, 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 December 31, 2013, 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.
	For the year ended December 31, 2013, JCG incurred $1.9 million of issuance costs related to the Credit Facility which are being amortized to interest expense over the remaining term of the Credit Facility.

	The accounting guidance for uncertainty in income taxes 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. The tax contingencies liability relates primarily to general state tax items and has been recorded in non-current liabilities and other accrued liabilities on JCG's Consolidated Balance Sheets, as appropriate.
	A reconciliation of the beginning and ending liability is as follows (in millions):
		December 31,

	Reduction due to settlement of audits		(0.4	)		(1.3	)		—
	End of year	$	5.6		$	5.9		$	7.4
	A deferred tax asset of $1.9 million is associated with the tax contingencies liability at December 31, 2013. If the tax contingencies liability and related deferred tax asset are reversed in future periods, the income tax provision would be favorably impacted by $3.7 million. As of December 31, 2013, JCG had $5.6 million of accrued reserves for income tax contingencies. JCG decreased its income tax contingency reserves in 2013 by $1.3 million as a result of the expiration of statutes of limitations and audit settlements, creating a net tax benefit of $0.8 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 on JCG's Consolidated Balance Sheets.
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, 2013, tax years from 2002 and forward remain subject to audit.
Taxing authorities generally charge interest and may assess penalties in the event that a tax position taken is subsequently reversed upon examination. JCG 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, 2013, 2012 and 2011, $1.3 million, $2.2 million and $3.4 million, respectively, 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. JCG 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. JCG records interest income from taxing authorities as a component of the income tax provision.

	Nonredeemable Noncontrolling Interests
	Noncontrolling interests that are not subject to redemption rights include employee ownership interests in two of JCG's subsidiaries, INTECH and Perkins, and third-party investors' ownership in consolidated seeded investment products. Certain of the Perkins ownership interests granted to employees became subject to redemption rights upon vesting in the first quarter 2013 at which time such interests were reclassified to redeemable noncontrolling interests.
	Nonredeemable noncontrolling interests as of December 31, 2013 and 2012, are summarized as follows (in millions):

	Nonredeemable noncontrolling interests in subsidiaries		4.9			4.8
	Total nonredeemable noncontrolling interests	$	13.7		$	17.2
	Changes in noncontrolling interests in consolidated seeded investment products were driven by two factors: changes in the market value of the underlying seeded investment products and changes in ownership of the underlying seeded investment products.

	Redeemable Noncontrolling Interests
	Redeemable noncontrolling interests consist of INTECH and Perkins interests that are currently redeemable. Also included are undistributed earnings due to the redeemable noncontrolling interests. As of December 31, 2013 and 2012, redeemable noncontrolling interests are summarized as follows (in millions):

	Undistributed earnings		1.4			2.8
	Total redeemable noncontrolling interests	$	7.3		$	42.9
	INTECH
	INTECH ownership interests held by a founding member have an estimated fair value of approximately $5.3 million and $4.8 million as of December 31, 2013 and 2012, respectively, representing approximately 1.0% aggregate ownership of INTECH for both periods. This founding member is entitled to retain his remaining INTECH interests until his death and has the option to require JCG to purchase from him his ownership interest of INTECH at fair value.
	Perkins
	Perkins noncontrolling interests subject to redemption rights had an estimated fair value of approximately $0.6 million and $35.3 million as of December 31, 2013 and 2012, respectively.
	On February 1, 2013, the noncontrolling owners of Perkins (who then owned 22.2% of the equity units of Perkins) exercised their right to put 98% of their equity units to JCG. Under the terms of the put, the noncontrolling ownership units were redeemed at fair value of $33.8 million as determined on August 31, 2013, six full months following the month of the put exercise. Following the redemption, JCG owned 99.6% of Perkins.
	On February 3, 2014, JCG exercised its right to purchase the remaining noncontrolling ownership units in Perkins of 0.4%. Under the terms of the call, the remaining noncontrolling ownership units will be 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. Refer to Note 11 — Long-Term Incentive Compensation for detailed information regarding the Perkins senior profits interests awards.

	Compensation cost associated with restricted stock includes $2.4 million, $(1.4) million and $3.5 million of amortization of INTECH interests granted to certain key employees of INTECH for the years ended December 31, 2013, 2012 and 2011, respectively. During the year ended December 31, 2012, compensation cost associated with restricted stock includes $3.6 million of amortization of INTECH interests and a $5.0 million benefit related to a restricted stock forfeiture as a result of the departure of a former INTECH executive. Compensation cost classified within restricted stock also includes $1.2 million of amortization of Perkins ownership interests granted to a Perkins employee for the years ended December 31, 2012 and 2011. There was no amortization of Perkins ownership interests in 2013.
	Historical long-term incentive awards have been granted with ratable vesting schedules between three and five years. The awards granted in 2013, 2012 and 2011 were generally granted with a four-year ratable vesting schedule and are generally not subject to accelerated vesting. INTECH also granted $3.1 million and $2.7 million of ownership interests to its employees in 2012 and 2011, respectively, which generally vest and will be recognized over a four-year period.
	At December 31, 2013, unrecognized compensation, net of estimated forfeitures and excluding mark-to-market adjustments on mutual fund share awards, and the weighted-average number of years over which the compensation cost will be recognized are summarized as follows (in millions):
		Unrecognized compensation			Weighted-

	Restricted stock awards		45.9			2.7
	Mutual fund share awards		56.2			2.6
	Total	$	102.8			2.6
	Unrecognized INTECH interests included in restricted stock awards in the table above totaled $4.3 million and will be recognized over a weighted-average period of 3.7 years.
	JCG generally grants annual long-term incentive awards in February of each year. The 2014 annual grant, not included in the table above, totaled $53.7 million and will generally be recognized ratably over a four-year period. The 2014 annual grant is not subject to performance-based accelerated vesting.
	Stock Options
	Stock options were granted to employees in 2013 and 2012. There were no stock options granted to employees in 2011 or in the 2014 annual grant.
	The fair value of stock options granted to JCG employees in 2013 and 2012 was estimated on the date of each grant using the Black-Scholes option pricing model with the following assumptions:
	Assumptions	2013			2012
	Dividend yield		2.47	%		2.33	%
	Expected volatility		64	%		66	%
	Risk-free interest rate		0.84	%		0.71	%
	Expected life		5 years			5 years
	Expected volatility was determined using an average of JCG's 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 2006 have a maximum contractual term of 10 years, and options granted thereafter have a maximum contractual term of seven years.

The total fair value of restricted stock that vested during the years ended December 31, 2013, 2012 and 2011, was $20.0 million, $13.2 million and $16.4 million, respectively.
Price-Vesting Units
JCG granted 249,100 price-vesting units to its Chief Executive Officer on December 30, 2011, totaling $1.2 million. These price-vesting units comprise two tranches of $0.6 million each. The first tranche is subject to a stock price hurdle representing a 27% premium over the $6.31 closing price of the Company's common stock on the date of grant, and the second tranche is subject to a stock price hurdle representing a 58% premium over the same closing price. Both tranches vest ratably over a four-year service period. To achieve each price hurdle, the Company's common stock must close at or above the prescribed price for 20 consecutive trading days at any time during the service period of the award. The units only vest if both the price hurdle and the service conditions are met. The stock price hurdle associated with the first tranche was achieved in 2012 and 29,400 units vested in 2012 and 2013. The stock price hurdle associated with the second tranche was achieved in December 2013 and 65,750 units vested. The price-vesting units award is required to be amortized using the graded-vesting method due to the underlying market conditions as represented by the stock price hurdles. In addition, the expense will be recognized irrespective of achieving the price hurdles provided service conditions are satisfied.
JCG granted 89,933 price-vesting units to its Chief Executive Officer on December 31, 2013, totaling $1.2 million. These price-vesting units may or may not vest, in whole or in part, three years after the date of grant, depending on JCG's three-year operating profit margin performance during the vesting period. If JCG's three-year operating margin performance is less than or equal to 27%, none of the shares will vest. Alternatively, if JCG's three-year operating margin performance equals 31%, 100% of the shares will vest. If JCG's three-year operating margin performance is greater than or equal to 35%, 200% of the shares will vest. All intermediate amounts between 27%, 31% and 35% will be interpolated on a straight-line basis.
Mutual Fund Share Awards
During 2013, 2012 and 2011, JCG granted employees $38.1 million, $39.8 million and $36.4 million, respectively, in awards that are indexed to certain mutual funds managed by the Company. The 2013 grant includes $16.0 million of performance-based mutual fund share awards. The performance-based mutual fund share awards vest five years after the grant date if certain performance fee criteria are achieved. Upon vesting, participants receive the value of the award adjusted for gains or losses attributable to the mutual funds to which the award was indexed, subject to tax withholding.
At December 31, 2013, the cost basis of unvested awards totaled $81.9 million.
Perkins Senior Profits Interests Awards
On December 31, 2008, Perkins granted senior profits interests awards designed to retain and incentivize key employees to grow the business. These awards vest on the fifth anniversary of grant and are entitled to a total of 5% of Perkins' annual taxable income. In addition, these awards have a formula-driven terminal value based on revenue and relative investment performance of products managed by Perkins. JCG can call and terminate any or all of the awards on the fifth, seventh or each subsequent anniversary of grant. JCG did not exercise its right to call on the fifth anniversary. Participants can require JCG to terminate the awards in exchange for the then-applicable formula price on the sixth anniversary of grant. The senior profits interests awards are also subject to termination at premiums or discounts to the formula at the option of JCG or the relevant employee, as applicable, upon certain corporate or employment-related events affecting Perkins or the relevant employee. As of December 31, 2013, the liability associated with the Perkins senior profits interests awards was $18.3 million (including undistributed earnings) included within accrued compensation and benefits on JCG's Consolidated Balance Sheets, and 100% of the awards have been amortized.
On November 18, 2013, Perkins granted additional senior profits interests awards which fully vest on December 31, 2018 and are entitled to a total of 10% of Perkins' annual taxable income. The entitlement to a percentage of Perkins' annual taxable income over the vesting period is tiered and starts at 2% in 2015 and increases 2% each year thereafter until reaching 10% after fully vesting on December 31, 2018. In addition, these awards have a formula-driven terminal value based on Perkins' revenue. JCG can call and terminate any or all of the awards on December 31, 2018 and each year thereafter. Holders of such interests can require JCG to purchase the interests in exchange for the then-applicable formula price on December 31, 2018. The senior profits interests are also subject to termination at premiums or discounts to the formula at the option of JCG or certain employees, as applicable, upon certain corporate or employment-related events affecting Perkins or certain employees. As of December 31, 2013, the formula driven value was zero and there was no liability on JCG's Consolidated Balance Sheets associated with the Perkins senior profits interests awards granted in 2013.
Long-Term Incentive Stock Plans
On May 10, 2005, JCG shareholders approved the 2005 Long-Term Incentive Stock Plan ("2005 Plan"), which allowed the Board of Directors to grant up to 15.0 million shares of equity-based awards, including stock options and restricted stock. Subsequent to the 2014 annual grant in January, approximately 2.0 million shares of equity-based awards are available to be granted under the 2005 Plan. On April 29, 2010, JCG shareholders approved the 2010 Long-Term Incentive Stock Plan ("2010 Plan"), which allows JCG to grant up to 4.4 million shares of equity-based awards, including stock options and restricted stock. On April 26, 2012, JCG shareholders approved an amendment to the 2010 Plan to increase the number of shares available to grant by 9.0 million shares for a total of 13.4 million shares of equity-based awards available to grant under the 2010 Plan. Subsequent to the 2014 annual grant in January, approximately 3.0 million shares of equity-based awards are available to be granted under the 2010 Plan.
JCG also has a 2012 Employment Inducement Award Plan ("EIA Plan") with 1.0 million shares of equity-based awards available to be granted as of December 31, 2013. The EIA Plan is not a shareholder-approved plan.

EARNINGS PER SHARE	'
	NOTE 14 — EARNINGS PER SHARE
	Basic earnings per common share is calculated by dividing net income attributable to JCG common shareholders 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, unvested restricted stock awards and price-vesting units. The following is a summary of the earnings per share calculation (in millions, except per share data):
		For the year ended December 31,
		2013		2012		2011
	Net income attributable to JCG common shareholders	$	114.7	$	102.3	$	142.9

	Diluted earnings per share	$	0.62	$	0.55	$	0.78
	Dividends paid per share	$	0.21	$	0.29	$	0.15
	On December 10, 2012, JCG's Board of Directors declared a regular quarterly cash dividend of $0.06 per share, which was paid on December 31, 2012, to stockholders of record at the close of business on December 21, 2012. This accelerated quarterly cash dividend was in place of the quarterly cash dividend scheduled to be declared in January 2013.
	On April 18, 2013, JCG's Board of Directors approved an increase of $0.01 per share, or 17%, in the Company's regular quarterly dividend. The approved quarterly rate of $0.07 per share represents an expected annualized dividend rate of $0.28 per share of common stock.
	The following stock options, unvested restricted stock and price-vesting units are anti-dilutive and have not been included in the weighted-average diluted shares outstanding calculation (in millions):
		For the year ended

	Other stock options		—		14		—
	Unvested restricted stock and price-vesting units		1.2		1.6		2.1
	All shares held in the JCG ESOP are treated as outstanding for purposes of computing basic earnings per share. The computation of diluted earnings per share does not include the impact of the 2014 Convertible Notes and 2018 Convertible Notes because the effect would be anti-dilutive as the conversion criteria have not been satisfied.

	JCG's capital lease obligations represent leased computer equipment. The carrying value of the obligations at December 31, 2013 and 2012, totaled $1.9 million and $2.9 million, respectively, and is included in other accrued liabilities and non-current liabilities on JCG's Consolidated Balance Sheets. The related lease terms extend through 2017.
	Investment Management Contracts
	Most of JCG's 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 JCG 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.

LITIGATION AND OTHER REGULATORY MATTERS	'
	NOTE 16 — LITIGATION AND OTHER REGULATORY MATTERS
	JCG is periodically involved in various legal proceedings and other regulatory matters. At December 31, 2013 and 2012, JCG had a $0.5 million and $0.2 million litigation accrual for all pending litigation matters, respectively. Possible losses in addition to this amount cannot be currently estimated, and as such, no additional accruals have been made. Although there can be no assurances, based on information currently available, management believes that it is probable that the ultimate outcome of matters that are pending or threatened will not have a material effect on JCG's consolidated financial condition.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
Basis of Presentation	'
	Basis of Presentation
	The financial statements include all majority-owned subsidiaries, and all intercompany accounts and transactions have been eliminated in consolidation. Events subsequent to the balance sheet date have been evaluated for inclusion in the accompanying financial statements through the issuance date.
Accounting Estimates	'
	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 and the differences could be material. JCG's significant estimates relate to investment securities, goodwill and intangible assets, equity compensation and income taxes.
Segment Information	'

Cash Equivalents	'
	Cash Equivalents
	Short-term investments with an initial maturity of three months or less when purchased, including investments in money market funds, are considered cash equivalents.
Property and Equipment	'
	Property and Equipment
	Property and equipment is recorded at cost. Depreciation and amortization are 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 $11.2 million, $13.4 million and $14.0 million for the years ended December 31, 2013, 2012 and 2011, respectively. Property and equipment is summarized as follows (in millions):
				December 31,
		Depreciation and
		amortization
		period		2013			2012
	Furniture, fixtures, computer equipment and software	3-7 years		$	199.3		$	191.9

	Less accumulated depreciation and amortization				(206.9	)		(195.7	)
	Property and equipment, net			$	29.9		$	33.3
	JCG 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 in an amount equal to the excess of the carrying amount of the asset over the fair value of the asset. There were no impairments of long-lived assets for the years ended December 31, 2013, 2012 and 2011.
Software	'
	Purchased software is recorded at cost and amortized over its estimated useful life. Internal and external costs incurred in connection with developing or obtaining software for internal use are expensed as incurred during the preliminary project stage, as are training and maintenance costs. Internal and external costs incurred for internal use software during the application development stage are capitalized until such time that the software is substantially complete and ready for its intended use. Application development stage costs are amortized on a straight-line basis over the estimated useful life of the software.
	Capitalized software costs totaled $8.3 million and $7.9 million at December 31, 2013 and 2012, respectively, and are presented within property and equipment, net on the Consolidated Balance Sheets.
Deferred Commissions	'
	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 redemptions reduce the unamortized deferred commissions balance. Amortization expense for the years ended December 31, 2013, 2012 and 2011, totaled $5.3 million, $5.6 million and $7.4 million, respectively.
	Deferred commissions, which are recorded as components of other current assets and non-current assets on the Consolidated Balance Sheets, are summarized as follows (in millions):
		December 31,
		2013			2012
	Deferred commissions — current	$	2.2		$	3
	Deferred commissions — non-current		0.3			0.4

Investment Securities	'
	Investment Securities
	JCG classifies investment 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 on JCG's Consolidated Balance Sheets at fair value and consist primarily of investments related to seeded investment products, investments in advised funds previously utilized for the economic hedging of mutual fund share awards and investments related to the economic hedging of deferred compensation.
	Seeded Investment Products
	JCG periodically adds new investment strategies to its investment product offerings by providing the initial cash investment or "seeding." The primary purpose of seeded investment products is to generate an investment performance track record in a product to attract third-party investors. JCG's initial investment in a new product represents 100% ownership in that product. Seeded investment products are initially consolidated and the individual securities within the portfolio are accounted for as trading securities. JCG consolidates such investment products as long as it holds a controlling interest in the investment product, defined as greater than 50% ownership.
	Upon deconsolidation, JCG continues to account for its investments in seeded products as trading securities if its ownership is between 20% and 50%. JCG may redeem invested seed capital for a variety of reasons, including when third-party investments in the relevant product are sufficient to sustain the given investment strategy. The length of time JCG holds a majority interest in a product varies based on a number of factors including, but not limited to, market demand, market conditions and investment performance. Changes in fair value of securities classified as trading are recognized in investment gains (losses), net on JCG's Consolidated Statements of Comprehensive Income.
	The Company has determined that its seeded investment products do not represent variable interest entities. Seed investments are made largely in mutual funds, but may also be made in commingled pools and separate accounts. JCG has determined mutual funds to be voting interest entities rather than variable interest entities. Commingled pools are established as limited liability companies or partnerships, and as such, the Company applies partnership accounting rules. These rules dictate that a managing member or general partner would not consolidate an entity if the members or limited partners carry substantive kick-out rights. All of the Company's commingled pools carry substantive kick-out rights. Seed investments in separate accounts are 100% owned by JCG and are accounted for as trading securities.
	Economic Hedging of Mutual Fund Share Awards and Deferred Compensation
	JCG grants mutual fund share awards to employees that are indexed to certain funds managed by JCG. Upon vesting, participants receive the value of the mutual fund share awards adjusted for gains or losses attributable to the mutual funds to which the award was indexed, subject to tax withholding. Historically, JCG made corresponding investments in JCG managed funds for purposes of economically hedging the mutual fund share awards. Effective January 2013, such corresponding investments are no longer made. The value of the investments in the JCG managed funds is a component of investment securities on JCG's Consolidated Balance Sheets.
	The Company maintains deferred compensation plans for certain highly compensated employees and members of its Board of Directors. 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 and its subsidiaries. The Company makes no contributions to the plan. To protect against market variability of the liability, the Company creates an economic hedge by investing in mutual funds that are consistent with the deferred amounts and mutual fund elections of the participants. Such investments remain assets of JCG. Changes in market value of the liability to participants are recognized as long-term incentive compensation in JCG's Consolidated Statements of Comprehensive Income and changes in the market value of the mutual fund securities are recognized in investment gains (losses), net on JCG's Consolidated Statements of Comprehensive Income.
	Available-for-Sale Securities
	Investment securities classified as available-for-sale consist of seeded investment products in which JCG holds a less than 20% interest and are carried on JCG's Consolidated Balance Sheets at fair value, and debt securities. The debt securities are classified as available-for-sale as JCG may not hold them to maturity. Changes in fair value are reflected as a component of other comprehensive (loss) income, net of tax on JCG's Consolidated Statements of 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 (losses), net on JCG's Consolidated Statements of Comprehensive Income. Accumulated gains and losses are reclassified to earnings when the securities are sold on a first-in, first-out cost basis.
	Held-to-Maturity Securities
	Investment securities are classified as held-to-maturity when JCG has the intent and ability to hold the securities to maturity. Held-to-maturity securities are carried on JCG's Consolidated Balance Sheets at cost with corresponding interest income reflected as other income, net on JCG's Consolidated Statements of Comprehensive 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 (losses), net on JCG's Consolidated Statements of Comprehensive Income. There were no held-to-maturity securities on JCG's Consolidated Balance Sheets for the years ended December 31, 2013 and 2012.
	Impairment Evaluation
	JCG 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, JCG considers the duration, extent and circumstances of any decline in fair value.
	For debt securities, an other-than-temporary impairment ("OTTI") is evident if JCG intends to sell the debt security or will more likely than not be required to sell the debt security before full recovery of the entire amortized cost basis is realized. However, even if JCG does not intend to sell the debt security and will not likely be required to sell the debt security before recovery of its entire amortized cost basis, JCG must evaluate expected cash flows to be received and determine if a credit loss has occurred. In the event of a credit loss, the credit component of the impairment is recognized within investment gains (losses) on JCG's Consolidated Statements of Comprehensive Income and the noncredit component is recognized through other comprehensive (loss) income, net of tax on JCG's Consolidated Statements of Comprehensive Income.
	For equity securities, JCG evaluates the securities in an unrealized loss position in the available-for-sale portfolio for OTTI on the basis of the duration of the decline in value of the security and severity of that decline as well as JCG's intent and ability to hold these securities for a period of time sufficient to allow for any anticipated recovery in the market value. If it is determined that the impairment on an equity security is other than temporary, an impairment loss equal to the difference between the carrying value of the security and its fair value is recognized within investment gains (losses) on JCG's Consolidated Statements of Comprehensive Income. There were no impairments of investment securities for the years ended December 31, 2013, 2012 and 2011.
Derivative Instruments	'
	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, futures contracts and forward contracts, respectively. These derivative instruments are not classified as hedges for accounting purposes. The Company records all derivatives as either assets or liabilities on JCG's Consolidated Balance Sheets and measures those investments at fair value. Changes in the value of the index swaps and futures contracts are recognized as a component of investment gains (losses), net on JCG's Consolidated Statements of Comprehensive Income. Changes in the value of the foreign currency forward contracts are recognized as a component of other income, net on JCG's Consolidated Statements of Comprehensive Income.
Fair Value Measurements	'
	Fair Value Measurements
	Fair value of assets and liabilities is determined using observable market data based on recent trading activity. Where observable market data is unavailable due to a lack of trading activity, JCG utilizes internally developed models to estimate fair value and independent third parties to validate assumptions, when appropriate. 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 JCG is valuing and the selected benchmark. Depending on the type of securities owned by JCG, other valuation methodologies may be required.
	Measurements of fair value are classified within a hierarchy based upon the transparency of inputs used in the valuation of an asset or liability. Classification within the hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
	The valuation hierarchy contains three levels:
	•
	Level 1 — Valuation inputs are unadjusted quoted market prices for identical assets or liabilities in active markets.
	•
	Level 2 — Valuation inputs are quoted market prices for identical assets or liabilities in markets that are not active, quoted market prices for similar assets and liabilities in active markets, and other observable inputs directly or indirectly related to the asset or liability being measured.
	•
	Level 3 — Valuation inputs are unobservable and significant to the fair value measurement.
	JCG's Level 1 and Level 2 fair value measurements consist of debt securities with maturities of 90 days or less carried within cash and cash equivalents, exchange-traded equity and debt securities underlying separate accounts and consolidated mutual funds and shares of unconsolidated mutual funds, investments in mutual funds related to the economic hedging of mutual fund share awards and deferred compensation plans, derivative instruments and long-term debt. The fair value level of consolidated seeded investment products is determined by the underlying securities of the product while the fair value level of equity-method and unconsolidated seeded investment products are valued using the respective net asset value ("NAV") of each product. All seeded investment products that utilize 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%.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 and are traded on exchanges outside of the U.S. 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. 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.
	JCG's Level 3 recurring fair value measurements primarily represent redeemable noncontrolling interests. Redeemable noncontrolling interests in INTECH are measured at fair value using a discounted cash flow methodology. Significant inputs to the discounted cash flow analysis include forecasted operating results, discount rate and terminal multiple of future cash flows. Redeemable noncontrolling interests in Perkins are measured by a contractual formula intended to represent fair value. See Note 6 — Fair Value Measurements for further discussion of the fair value of redeemable noncontrolling interests.
	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.
Income Taxes	'
	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. The effect of changes in tax rates on deferred tax assets and liabilities is recognized in the period that includes the enactment date. Significant management judgment is required in developing JCG's provision for income taxes, including the valuation allowances that might be required against deferred tax assets and the evaluation of various income tax contingencies.
	The accounting guidance for uncertainty in income taxes 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. The tax contingencies liability relates primarily to general state tax items and has been recorded in other liabilities and other accrued liabilities on JCG's Consolidated Balance Sheets, as appropriate.
	Taxing authorities generally charge interest and may assess penalties in the event that a tax position taken is subsequently reversed upon examination. JCG 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, 2013, 2012 and 2011, $1.3 million, $2.2 million and $3.4 million, respectively, 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. JCG 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. JCG records interest income from taxing authorities as a component of the income tax provision.
Goodwill and Intangible Assets, Net	'
	Goodwill and Intangible Assets, Net
	Goodwill represents the excess of cost over the fair value of the identifiable net assets of acquired companies. JCG's identifiable intangible assets generally represent the cost of client relationships and mutual fund advisory contracts acquired as well as brand name and trademark. Goodwill and indefinite-lived intangible assets are tested for impairment annually as of October 1 or more frequently if events or circumstances indicate that the carrying value may not be recoverable. Intangible assets subject to amortization are tested for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. 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.
Noncontrolling Interests and Redeemable Noncontrolling Interests	'
	Noncontrolling Interests and Redeemable Noncontrolling Interests
	Noncontrolling interests that are not subject to redemption rights are classified in permanent equity. Redeemable noncontrolling interests are classified outside of permanent equity on the Consolidated Balance Sheets and are measured at estimated fair value as of the balance sheet dates. Changes in fair value of redeemable noncontrolling interests are recognized as increases or decreases to redeemable noncontrolling interests with an offsetting charge to retained earnings. Certain of the INTECH and Perkins ownership interests granted to employees become subject to redemption rights upon vesting at which time such interests are reclassified to redeemable noncontrolling interests. Earnings attributable to noncontrolling interests that are and are not subject to redemption rights are combined in JCG's Consolidated Statements of Comprehensive Income. Acquisitions of entities in which JCG holds an existing controlling interest are treated as a reduction of noncontrolling interests or redeemable noncontrolling interests in an amount equal to the purchase price. See Note 10 — Noncontrolling Interests for further discussion of noncontrolling interests.
Revenue Recognition	'
	Revenue Recognition
	Investment management and shareowner servicing fees are recognized as services are provided. These revenues are generally determined in accordance with contracts based upon a percentage of average assets under management.
	Performance fee revenue is derived from certain mutual funds and separate accounts. Mutual fund performance fees represent an adjustment to the investment management fee of certain mutual funds and are based on the relative investment performance of each fund compared to a specific benchmark index. The adjustment is up to a positive or negative 15 basis points and is calculated using each fund's daily net average assets based on a trailing 36-month measurement period. Separate 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. Separate account performance fees are recognized at the end of the contractual period if the stated performance criteria are achieved.
Marketing	'
	Marketing
	Marketing and promotional costs are generally expensed as incurred.
Stock-Based Compensation	'
	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 and consists 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 market price on date of grant. The Black-Scholes model requires management to estimate certain variables, including the lives of options from grant date to exercise date, the volatility of the underlying shares and future dividend rates.
	JCG estimates, at the time of grant, the amount of awards that are not expected to vest based on historical forfeiture rates and subsequently records adjustments, as appropriate.
