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 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 2015 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 2014 Annual Report.

FAIR VALUE MEASUREMENTS.

Fair Value Disclosures [Abstract]

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.

EFFECT OF SPECIAL CASH DIVIDEND.

As a result of the special cash dividend declared by the Board of Directors in February 2015, the anti-dilution provisions of our employee long-term incentive plans and non-employee director plans (collectively the LTI Plans) require an automatic adjustment to neutralize the effect of the special dividend. On the special dividend's ex-dividend date (April 7, 2015), the number of shares authorized and the number of stock options outstanding and their exercise price were adjusted resulting in an increase of 749,578 stock options outstanding on the ex-dividend date, and no incremental compensation expense. The stock option table above will be adjusted to reflect the impact in the second quarter of 2015.

RESTRICTED SHARES AND STOCK UNITS.

The following table summarizes the status of and changes in our nonvested restricted shares and restricted stock units during the first quarter of 2015.

The nonvested at March 31, 2015, includes 28,800 performance-based restricted shares and 175,500 performance-based restricted stock units. These performance-based restricted shares and units include 22,800 restricted shares and 121,050 restricted stock units for which the performance period has lapsed and the performance threshold has been met.

The following table presents the compensation expense (in millions) to be recognized over the remaining vesting periods of the stock-based awards outstanding at March 31, 2015.

NOTE 8	– EARNINGS PER SHARE CALCULATIONS.

The following table presents the reconciliation (in millions) of our net income to net income allocated to our common stockholders and the weighted-average shares (in millions) that are used in calculating the basic and diluted earnings per share on our common stock. Weighted-average common shares outstanding assuming dilution reflects the potential dilution, determined using the treasury stock method, that could occur if outstanding stock options were exercised and non-participating stock awards vested.

Stock options, weighted-average exercise price
Effect of special dividend	As a result of the special cash dividend declared by the Board of Directors in February 2015, the anti-dilution provisions of our employee long-term incentive plans and non-employee director plans (collectively the LTI Plans) require an automatic adjustment to neutralize the effect of the special dividend. On the special dividend's ex-dividend date (April 7, 2015), the number of shares authorized and the number of stock options outstanding and their exercise price were adjusted resulting in an increase of 749,578 stock options outstanding on the ex-dividend date, and no incremental compensation expense.
