Organization, Consolidation and Presentation of Financial Statements [Abstract]
The company and basis of preparation	NOTE 1 – THE COMPANY AND BASIS OF PREPARATION. T. Rowe Price Group (Price Group) derives its consolidated revenues and net income primarily from investment advisory services that its subsidiaries provide to individual and institutional investors in the sponsored T. Rowe Price U.S. mutual funds and other investment portfolios, including separately managed accounts, subadvised funds, and other sponsored investment portfolios. We also provide our investment advisory clients with related administrative services, including distribution, mutual fund transfer agent, accounting, and shareholder services; participant recordkeeping and transfer agent services for defined contribution retirement plans; brokerage; and trust services. Investment advisory revenues depend largely on the total value and composition of assets under our management. Accordingly, fluctuations in financial markets and in the composition of assets under management impact our revenues and results of operations. These unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States, which require the use of estimates and reflect all adjustments that are, in the opinion of management, necessary to a fair statement of our results for the interim periods presented. All such adjustments are of a normal recurring nature. Actual results may vary from our estimates. Certain prior year amounts have been reclassified to conform to the 2016 presentation. The unaudited interim financial information contained in these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in our 2015 Annual Report. NEW ACCOUNTING GUIDANCE. We implemented Accounting Standards Update No. 2015-02 - Consolidation (Topic 810): Amendments to the Consolidation Analysis on January 1, 2016, which did not require the restatement of prior year periods. In connection with the adoption of this guidance, we reevaluated all of our investments for consolidation, including our investments in sponsored investment portfolios. The adoption of the guidance resulted in sponsored investment products regulated outside the U.S. previously accounted for as voting interest entities (VOE) to be evaluated as variable interest entities (VIE) and led to the consolidation of an additional 24 portfolios that were previously accounted for as available-for-sale securities. The adoption also resulted in the consolidation of an additional eight U.S. sponsored investment portfolios that were previously accounted for as available-for sale-securities. The impact to the condensed consolidated balance sheet upon adoption was the consolidation of $1.6 billion of assets, $21.3 million of liabilities, and $672.7 million of non-controlling interests. We also reclassified $32.5 million in accumulated comprehensive income to retained earnings. The consolidation guidance provides a scope exception for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. Additional disclosures relating to consolidated voting interest entities and variable interest entities, and the impact the new accounting guidance has had on the quarter are included in Note 5. CONSOLIDATION. Our condensed consolidated financial statements include the accounts of all subsidiaries and sponsored investment portfolios in which we have a controlling interest. We are generally deemed to have a controlling interest when we own the majority of the voting interest of an entity or deemed to be the primary beneficiary of a VIE. We perform an analysis of our investments to determine if the investment entity is a VOE or VIE. Our analysis involves judgment and considers several factors, including an entity’s legal organization, capital structure, the rights of the equity investment holders, our ownership interest in the entity, and our contractual involvement with the entity. We continually review and reconsider our previously reached VIE or VOE conclusions upon the occurrence of certain events, such as changes to our ownership interest, changes to an entity’s organization and legal structure, or amendments to governing documents. All material accounts and transactions between consolidated entities are eliminated in consolidation. Upon consolidation of sponsored investment portfolios, the Company retains the specialized investment company accounting principles of the underlying funds. All of the underlying investments held by these portfolios are carried at fair value with corresponding changes in the investments’ fair values reflected in non-operating income (expense) on the condensed consolidated statements of income. Variable interest entities VIEs are entities that, by design (i ) lack sufficient equity to permit the entity to finance its activities independently, or (ii) have equity holders that do not have the power to direct the activities of the entity that most significantly impact the entity’s economic performance, the obligation to absorb the entity’s losses, or the rights to receive the entity’s residual returns. We consolidate a VIE when we are the primary beneficiary, which is the party that has both (i) the power to direct the activities of the VIE that most significantly impact its economic performance and (ii) the obligation to absorb losses of the entity or the right to receive benefits from the VIE that could potentially be significant. Our Luxembourg-based SICAV (Société d'Investissement à Capital Variable) funds and other sponsored investment portfolios regulated outside the U.S. are determined to be VIEs. Along with VIEs that we consolidate, we also hold variable interests in other VIEs, including several investment partnerships, that are not consolidated because we are not the primary beneficiary. Redeemable non-controlling interests We recognize redeemable non-controlling interests for the portion of the net assets of our consolidated sponsored investment portfolios held by unrelated third party investors as their interest is convertible to cash and other assets at their option. As such, we reflect redeemable non-controlling interests as temporary equity in our condensed consolidated balance sheet.

The carrying value of investments (in millions) we do not consolidate are as follows: 12/31/2015 3/31/2016 Available-for-sale sponsored investment portfolios $ 1,612.3 $ 573.9 Equity method investments 26% interest in UTI Asset Management Company Limited (India) 132.8 134.8 Sponsored investment portfolios 113.7 276.3 Investment partnerships 6.2 5.6 Sponsored investment portfolios held as trading 25.8 47.4 Cost method investments 69.4 69.0 U.S. Treasury note 1.0 1.0 Total $ 1,961.2 $ 1,108.0 In connection with the adoption of the new consolidation accounting guidance on January 1, 2016, we reevaluated all of our investments for consolidation, including our investments in sponsored investment portfolios. We determined that our interests in a number of our available-for-sale holdings held at December 31, 2015, were deemed controlling interests under the new accounting standard and resulted in these sponsored investment portfolios being consolidated on January 1, 2016. During the first quarter of 2016, we also deconsolidated certain sponsored investment portfolios, in which we provided initial seed capital at the time of formation, as we no longer had a controlling interest. Accordingly, we deconsolidated from our condensed consolidated balance sheet the portfolio’s assets of $338.8 million , liabilities of $.9 million and redeemable non-controlling interests of $152.6 million , which were the carrying values on the deconsolidation dates. Since our consolidated investment portfolios were carried at fair value, and the investment portfolio's functional currency was U.S. dollars, we did not recognize any gain or loss in our consolidated statement of income upon deconsolidation. Depending on our ownership interest, we are now reporting our residual interests in these sponsored investment portfolios as either equity method or available-for-sale investments. AVAILABLE-FOR-SALE SPONSORED INVESTMENT PORTFOLIOS. The available-for-sale sponsored investment portfolios (in millions) include: Aggregate cost Unrealized holding Aggregate fair value gains losses December 31, 2015 Stock and blended asset funds $ 428.6 $ 180.3 $ (9.1 ) $ 599.8 Bond funds 990.5 39.1 (17.1 ) 1,012.5 Total $ 1,419.1 $ 219.4 $ (26.2 ) $ 1,612.3 March 31, 2016 Stock and blended asset funds $ 108.0 $ 84.4 $ (.4 ) $ 192.0 Bond funds 380.3 3.7 (2.1 ) 381.9 Total $ 488.3 $ 88.1 $ (2.5 ) $ 573.9 The following table details the number of holdings, the unrealized holding losses, and the aggregate fair value of available-for-sale sponsored investment portfolios with unrealized losses categorized by the length of time they have been in a continuous unrealized loss position: Number of holdings Unrealized holding losses Aggregate December 31, 2015 Less than 12 months 18 $ (15.8 ) $ 419.6 12 months or more 4 (10.4 ) 298.6 Total 22 $ (26.2 ) $ 718.2 March 31, 2016 Less than 12 months 8 $ (.3 ) $ 27.9 12 months or more 1 (2.2 ) 168.6 Total 9 $ (2.5 ) $ 196.5 In addition to the duration of the impairments, we reviewed the severity of the impairment as well as our intent and ability to hold the investments for a period of time sufficient for an anticipated recovery in fair value. Accordingly, impairment of these investment holdings is considered temporary at December 31, 2015 , and March 31, 2016 . VARIABLE INTEREST ENTITIES. Our investments at March 31, 2016 , include $81.2 million of investments in variable interest entities that we do not consolidate as we are not deemed the primary beneficiary. Our maximum risk of loss related to our involvement with these entities at March 31, 2016 , is $140.8 million , which includes our carrying value, any unfunded capital commitments, and uncollected investment advisory and administrative fees.

Fair value measurements
Fair value measurements	NOTE 4 – FAIR VALUE MEASUREMENTS. We determine the fair value of our cash equivalents and certain investments using the following broad levels of inputs as defined by related accounting standards: Level 1 – quoted prices in active markets for identical securities. Level 2 – observable inputs other than Level 1 quoted prices including, but not limited to, quoted prices for similar securities, interest rates, prepayment speeds, and credit risk. These inputs are based on market data obtained from independent sources. Level 3 – unobservable inputs reflecting our own assumptions based on the best information available. We do not value any investments using Level 3 inputs. These levels are not necessarily an indication of the risk or liquidity associated with our investments. There have been no material transfers between the levels. The following table summarizes our investments (in millions) that are recognized in our condensed consolidated balance sheets using fair value measurements determined based on the differing levels of inputs.

Rowe Price Group 150.4 792.6 943.0 $ 219.6 $ 1,548.5 $ 1,768.1 Although we can redeem our net interest in these sponsored investment portfolios at any time, we cannot directly access or sell the assets held by the portfolios to obtain cash for general operations. Additionally, the assets of these investment portfolios are not available to our general creditors. Since third party investors in these investment funds have no recourse to Price Group’s credit, our overall risk related to the net assets of consolidated sponsored investment portfolios is limited to valuation changes associated with our net interest. We, however, are required to recognize the valuation changes associated with all underlying investments held by these portfolios in our condensed consolidated statements of income, and disclose the portion attributable to third party investors as net income attributable to redeemable non-controlling interests. The operating results (in millions) of the consolidated sponsored investment portfolios for the three months ended March 31, 2016 , are reflected in our condensed consolidated statement of income as follows: Voting Variable interest entities Total Operating expenses reflected in net operating income $ (.5 ) $ (2.1 ) $ (2.6 ) Net investment income reflected in non-operating income 6.3 17.5 23.8 Impact on income before taxes $ 5.8 $ 15.4 $ 21.2 Attributable to redeemable non-controlling interests $ 2.0 $ 7.2 $ 9.2 Attributable to T.

These cash flows were eliminated in consolidation. FAIR VALUE MEASUREMENTS. We determine the fair value of investments held by consolidated sponsored investment portfolios using the following broad levels of inputs as defined by related accounting standards: Level 1 – quoted prices in active markets for identical securities. Level 2 – observable inputs other than Level 1 quoted prices including, but not limited to, quoted prices for similar securities, interest rates, prepayment speeds, and credit risk. These inputs are based on market data obtained from independent sources. Level 3 – unobservable inputs reflecting our own assumptions based on the best information available. We do not value any investments using Level 3 inputs. These levels are not necessarily an indication of the risk or liquidity associated with these investment holdings. There have been no material transfers between the levels.

New accounting guidance	NEW ACCOUNTING GUIDANCE. We implemented Accounting Standards Update No. 2015-02 - Consolidation (Topic 810): Amendments to the Consolidation Analysis on January 1, 2016, which did not require the restatement of prior year periods. In connection with the adoption of this guidance, we reevaluated all of our investments for consolidation, including our investments in sponsored investment portfolios. The adoption of the guidance resulted in sponsored investment products regulated outside the U.S. previously accounted for as voting interest entities (VOE) to be evaluated as variable interest entities (VIE) and led to the consolidation of an additional 24 portfolios that were previously accounted for as available-for-sale securities. The adoption also resulted in the consolidation of an additional eight U.S. sponsored investment portfolios that were previously accounted for as available-for sale-securities. The impact to the condensed consolidated balance sheet upon adoption was the consolidation of $1.6 billion of assets, $21.3 million of liabilities, and $672.7 million of non-controlling interests. We also reclassified $32.5 million in accumulated comprehensive income to retained earnings. The consolidation guidance provides a scope exception for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. Additional disclosures relating to consolidated voting interest entities and variable interest entities, and the impact the new accounting guidance has had on the quarter are included in Note 5.
Consolidation	CONSOLIDATION. Our condensed consolidated financial statements include the accounts of all subsidiaries and sponsored investment portfolios in which we have a controlling interest. We are generally deemed to have a controlling interest when we own the majority of the voting interest of an entity or deemed to be the primary beneficiary of a VIE. We perform an analysis of our investments to determine if the investment entity is a VOE or VIE. Our analysis involves judgment and considers several factors, including an entity’s legal organization, capital structure, the rights of the equity investment holders, our ownership interest in the entity, and our contractual involvement with the entity. We continually review and reconsider our previously reached VIE or VOE conclusions upon the occurrence of certain events, such as changes to our ownership interest, changes to an entity’s organization and legal structure, or amendments to governing documents. All material accounts and transactions between consolidated entities are eliminated in consolidation. Upon consolidation of sponsored investment portfolios, the Company retains the specialized investment company accounting principles of the underlying funds. All of the underlying investments held by these portfolios are carried at fair value with corresponding changes in the investments’ fair values reflected in non-operating income (expense) on the condensed consolidated statements of income. Variable interest entities VIEs are entities that, by design (i ) lack sufficient equity to permit the entity to finance its activities independently, or (ii) have equity holders that do not have the power to direct the activities of the entity that most significantly impact the entity’s economic performance, the obligation to absorb the entity’s losses, or the rights to receive the entity’s residual returns. We consolidate a VIE when we are the primary beneficiary, which is the party that has both (i) the power to direct the activities of the VIE that most significantly impact its economic performance and (ii) the obligation to absorb losses of the entity or the right to receive benefits from the VIE that could potentially be significant. Our Luxembourg-based SICAV (Société d'Investissement à Capital Variable) funds and other sponsored investment portfolios regulated outside the U.S. are determined to be VIEs. Along with VIEs that we consolidate, we also hold variable interests in other VIEs, including several investment partnerships, that are not consolidated because we are not the primary beneficiary. Redeemable non-controlling interests We recognize redeemable non-controlling interests for the portion of the net assets of our consolidated sponsored investment portfolios held by unrelated third party investors as their interest is convertible to cash and other assets at their option. As such, we reflect redeemable non-controlling interests as temporary equity in our condensed consolidated balance sheet.
