The company and basis of preparation	'
	NOTE 1	– THE COMPANY AND BASIS OF PREPARATION.
	T. Rowe 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 items have been reclassified to conform to current year 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 2013 Annual Report.

	The securities held by consolidated sponsored investment portfolios, sponsored fund investments held as trading, and the sponsored fund investments treated as equity method investments relate to investment portfolios in which we provided initial seed capital at the time of its formation. We have determined at December 31, 2013 and September 30, 2014, that these investment portfolios are voting interest entities and, as a result, have consolidated those sponsored portfolios in which we own a majority of the voting interest.
	During the third quarter of 2014, we deconsolidated certain sponsored investment portfolios, in which we provided initial seed capital at the time of its formation, as we no longer had a controlling financial interest. Accordingly, we deconsolidated the carrying value of the investments held as trading, which was $25.5 million at the deconsolidation dates, and are reporting our residual interest in these sponsored investment portfolios as an equity method investment. Since our consolidated investment portfolios were carried at fair value, we did not recognize any gain or loss in our condensed consolidated statement of income upon deconsolidation. The impact of the deconsolidation on our condensed consolidated balance sheet was immaterial.

Fair value measurements	'
	NOTE 5	– FAIR VALUE MEASUREMENTS.
	We determine the fair value of our 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.
