Organization, Consolidation and Presentation of Financial Statements [Abstract]

Prior to 2014, the Company was a wholly-owned subsidiary of Old Mutual plc (“OM plc”), an international long-term savings, protection and investment group, listed on the London Stock Exchange. On October 15, 2014, the Company completed the initial public offering (the “Offering”) by OM plc pursuant to the Securities Act of 1933, as amended. Additionally, between the Offering and February 25, 2019, the Company, OM plc and/or HNA Capital U.S. (“HNA”) completed a series of transactions in the Company’s shares, including a two-step transaction announced on March 25, 2017 for a sale by OM plc of a 24.95% shareholding in the Company to HNA and a two-step transaction announced on November 19, 2018 for a sale of the substantial majority of the ordinary shares held by HNA of the Company to Paulson & Co. (“Paulson”). On February 25, 2019, this transaction was completed and Paulson held approximately 21.7% of the ordinary shares of the Company. The remaining shares held by HNA were bought back by the Company in the first quarter of 2019.

On March 2, 2018, the Company announced the change of its name from OM Asset Management plc to BrightSphere Investment Group plc.

On July 12, 2019, the BrightSphere corporate group, which consisted of BrightSphere Investment Group plc, a public company limited by shares incorporated under the laws of England and Wales and its operating subsidiaries (such operating subsidiaries and the holding company collectively, the “BrightSphere Group”), completed a redomestication, resulting in BrightSphere Investment Group Inc., a Delaware corporation, becoming the publicly traded parent company of BrightSphere Group (the “Redomestication”). The scheme of arrangement pursuant to which the Redomestication was effected was approved by the Company’s shareholders and the High Court of Justice of England and Wales. Effective as of the close of business on July 12, 2019, all issued ordinary shares of BrightSphere Investment Group plc were exchanged on a one-for-one basis for newly issued shares of common stock of BrightSphere Investment Group Inc. As a result, all outstanding shareholders of BrightSphere Investment Group plc became common stockholders of BrightSphere Investment Group Inc. The common stock of BrightSphere Investment Group Inc. began trading on July 15, 2019, and the Company’s trading symbol on the NYSE remained unchanged as “BSIG.”
