Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of the Business	Organization and Description of the Business BrightSphere Investment Group Inc. (“BrightSphere”, “BSIG” or the “Company”), through its subsidiaries, is a global asset management company. The Company provides investment management services globally to predominantly institutional investors. The Company historically held interests in a diverse group of investment management firms (the “Affiliates”) individually headquartered in the United States. The Company completed the disposition of certain Affiliates and currently operates the business through one Affiliate, Acadian Asset Management LLC (“Acadian”), within its Quant & Solutions reportable segment: • Quant & Solutions —comprised of versatile, often highly-tailored strategies that leverage data and technology in a computational, factor-based investment process across a range of asset classes in developed and emerging markets, including global, non-U.S. and small-cap equities, as well as managed volatility, ESG, multi-asset, equity alternatives, and long/short strategies. Acadian is organized as a limited liability company. Fees for services are largely asset-based and, as a result, the Company’s revenue fluctuates based on the performance of financial markets and investors’ asset flows in and out of the Company’s products. The Company utilizes a profit-sharing model in structuring its compensation and ownership with Acadian. Variable compensation is based on the firm’s profitability. BSIG and Acadian key employees share in profits after variable compensation according to their respective ownership interests. The profit-sharing model results in the alignment of BSIG and Acadian key employee economic interests, which is critical to the Company’s talent management strategy and long-term growth of the business. The corporate head office is included within the Other category, along with the Company’s previously disposed affiliates, Campbell Global, LLC (“Campbell Global”) and Investment Counselors of Maryland (“ICM”), for the prior year period. 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 shares held by HNA of the Company to Paulson & Co. Inc. (“Paulson”). On February 25, 2019, this transaction was completed and Paulson held approximately 21.7% of the shares of the Company. The remaining shares held by HNA were bought back by the Company in the first quarter of 2019.

Within these Condensed Consolidated Financial Statements, Paulson and its related entities, as defined above, are referred to as “related parties.” The Condensed Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). In the opinion of management, all normal and recurring adjustments considered necessary for a fair presentation of the Company’s Condensed Consolidated Financial Statements have been included.

Certain disclosures included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (annual report on Form 10-K) are not required to be included on an interim basis in the Company’s quarterly reports on Form 10-Q. The Company has condensed or omitted these disclosures.

The Company’s significant accounting policies, which have been consistently applied, are summarized in those financial statements. Use of estimates The preparation of these Condensed Consolidated Financial Statements 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 period. Actual results could differ from such estimates, and the differences may be material to the Condensed Consolidated Financial Statements. New accounting standards not yet adopted The Company has considered all newly issued accounting guidance that is applicable to the Company’s operations and the preparation of the unaudited Condensed Consolidated Financial Statements, including those that have not yet been adopted. The Company does not believe that any such guidance has or will have a material effect on its Condensed Consolidated Financial Statements and related disclosures.

On June 2, 2021, the Company completed the sale of all its interests in Landmark to Ares for cash consideration of $690.0 million, adjusted for customary closing adjustments. The Company recognized a gain on disposal of discontinued operations of $509.2 million, net of tax of $176.6 million for the three and six months ended June 30, 2021. The divestiture of Landmark met the discontinued operations criteria as it represented a strategic shift that had a major effect on the Company’s operations and financial results. The Company redeemed co-investments of $31.5 million in Landmark’s funds as of June 2, 2021 upon consummation of the sale. Thompson, Siegel & Walmsley, LLC On May 9, 2021, the Company entered into an agreement with Pendal Group Limited (“Pendal”), to sell all of the Company’s interests in Thompson, Siegel & Walmsley, LLC (“TSW”) and the Company’s seed investment in TSW strategies. On July 22, 2021, the Company completed the sale of all its interests in TSW to Pendal for cash consideration of $240.0 million. The divestiture of TSW met the discontinued operations criteria as it represented a strategic shift that has a major effect on the Company’s operations and financial results. The major classes of revenue and expenses constituting net income from discontinued operations attributable to controlling interests for Landmark and TSW in the Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2022 and 2021 are as follows (in millions): Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Revenues $ — $ 51.3 $ — $ 109.5 Operating expenses: Compensation and benefits — 43.8 — 87.6 General and administrative expenses — 3.3 — 7.7 Amortization of intangibles — 1.1 — 2.7 Depreciation and amortization — 0.2 — 0.5 Consolidated Funds’ expense — — — 0.1 Total operating expenses — 48.4 — 98.6 Operating income — 2.9 — 10.9 Investment gains of consolidated Funds — 51.5 — 68.1 Income from discontinued operations before taxes — 54.4 — 79.0 Income tax expense — 1.0 — 3.7 Income from discontinued operations, net of tax — 53.4 — 75.3 Gain on disposal, net of tax of $0.0, $176.6, $0.0, and $176.6 — 509.2 — 509.2 Total discontinued operations — 562.6 — 584.5 Income from discontinued operations attributable to non-controlling interests — 54.6 — 68.0 Net income from discontinued operations attributable to controlling interests $ — $ 508.0 $ — $ 516.5 Consolidated Funds In connection with the sale of Landmark on June 2, 2021, the Company transferred its co-investment interests in Landmark funds to Ares for $31.5 million.

Fair Value Measurements	Fair Value Measurements The following table summarizes the Company’s assets that are measured at fair value on a recurring basis at June 30, 2022 (in millions): Quoted prices Significant Significant Uncategorized Total value, Assets (1) Investments in separate accounts (2) 4.0 — — — 4.0 Investments related to long-term incentive compensation plans (3) 40.9 — — — 40.9 Investments in unconsolidated Funds (4) — — — 4.2 4.2 Total fair value assets $ 44.9 $ — $ — $ 4.2 $ 49.1 The following table summarizes the Company’s assets that are measured at fair value on a recurring basis at December 31, 2021 (in millions): Quoted prices Significant Significant Uncategorized Total value December 31, 2021 Assets (1) Investments in separate accounts (2) 4.6 — — — 4.6 Investments related to long-term incentive compensation plans (3) 45.0 — — — 45.0 Investments in unconsolidated Funds (4) — — — 4.9 4.9 Total fair value assets $ 49.6 $ — $ — $ 4.9 $ 54.5 (1) Assets measured at fair value are comprised of financial investments managed by the Company's Affiliates. Equity securities, including common and preferred stock and short-term investment funds which are traded on a national securities exchange are stated at the last reported sales price on the day of valuation. To the extent these securities are actively traded and valuation adjustments are not applied, they are classified as Level I. The securities that trade in markets that are not considered to be active but are valued based on quoted market prices, dealer quotations or alternative pricing sources supported by observable inputs obtained by the Company from independent pricing services are classified as Level II. The Company obtains prices from independent pricing services that may utilize broker quotes, but generally the independent pricing services will use various other pricing techniques which take into account appropriate factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data. The Company has not made adjustments to the prices provided. If the pricing services are only able to (a) obtain a single broker quote or (b) utilize a pricing model, such securities are classified as Level III. If the pricing services are unable to provide prices, the Company attempts to obtain one or more broker quotes directly from a dealer or values such securities at the last bid price obtained. In either case, such securities are classified as Level III. The Company performs due diligence procedures over third party pricing vendors to understand their methodology and controls to support their use in the valuation process to ensure compliance with required accounting disclosures. (2) Investments in separate accounts of $4.0 million at June 30, 2022 consist of approximately 100% of equity securities and other investments. Investments in separate accounts of $4.6 million at December 31, 2021 consist of approximately 100% of equity securities and other investments. The Company values these using the published price of the underlying securities (classified as Level I) or quoted price supported by observable inputs as of the measurement date (classified as Level II). (3) Investments related to long-term incentive compensation plans of $40.9 million and $45.0 million at June 30, 2022 and December 31, 2021, respectively, were investments in publicly registered daily redeemable funds (some managed by Affiliates), which the Company has classified as trading securities and valued using the published price as of the measurement dates. Accordingly, the Company has classified these investments as Level I. (4) The uncategorized amounts of $4.2 million and $4.9 million at June 30, 2022 and December 31, 2021, respectively, relate to investments in unconsolidated Funds which consist primarily of investments in Funds and are valued using NAV which the Company relies on to determine their fair value as a practical expedient and has therefore not classified these investments in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to amounts presented in the Condensed Consolidated Balance Sheets. These unconsolidated Funds consist primarily of real estate investment Funds, UCITS and other investment vehicles. The NAVs that have been provided by investees have been derived from the fair values of the underlying investments as of the measurement dates. UCITS and other investment vehicles are not subject to redemption restrictions. The real estate investment Funds of $4.2 million and $4.8 million at June 30, 2022 and December 31, 2021, respectively, are subject to longer than quarterly redemption restrictions, and due to their nature, distributions are received only as cash flows are generated from underlying assets over the life of the Funds. The range of time over which the underlying assets are expected to be liquidated by the investees is approximately one year from June 30, 2022. The valuation process for the underlying real estate investments held by the real estate investment Funds begins with each property or loan being valued by the investment teams. The valuations are then reviewed and approved by the valuation committee, which consists of senior members of the portfolio management, acquisitions, and research teams. For certain properties and loans, the valuation process may also include a valuation by independent appraisers. In connection with this process, changes in fair value measurements from period to period are evaluated for reasonableness, considering items such as market rents, capitalization and discount rates, and general economic and market conditions. The following table reconciles the opening balances of Level III financial assets to closing balances at the end of the period (in millions): Three Months Ended June 30, Six Months Ended June 30, Investments in unconsolidated Funds 2022 2021 2022 2021 Level III financial assets At beginning of the period $ — $ 2.5 $ — $ 2.5 Additions (redemptions) — (0.1) — (0.1) Disposals — (2.7) — (2.7) Total net fair value gains/losses recognized in net income — 0.3 — 0.3 Total Level III financial assets $ — $ — $ — $ — There were no significant transfers of financial assets or liabilities between Levels II or III during the three and six months ended June 30, 2022 and 2021, respectively.

Variable Interest Entities

Variable Interest Entities	6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities The Company, through its Affiliate, sponsors the formation of various entities considered to be VIEs. These VIEs are primarily Funds managed by the Company’s Affiliate and other partnership interests typically owned entirely by third party investors. Certain Funds may be capitalized with seed capital investments from the Company and may be owned partially by Affiliate key employees and/or individuals that own non-controlling interests in the Affiliate. The Company’s determination of whether it is the primary beneficiary of a Fund that is a VIE is based in part on an assessment of whether or not the Company and its related parties are exposed to more than an insignificant amount of the risks and rewards of the entity. Typically, the Fund’s investors are entitled to substantially all of the economics of these VIEs with the exception of the management fees and performance fees, if any, earned by the Company or any investment the Company has made into the Funds. The Company generally is not the primary beneficiary of Fund VIEs created to manage assets for clients unless the Company’s ownership interest, including interests of related parties, is substantial. The Company did not consolidate any funds that are VIEs as of June 30, 2022 and December 31, 2021. The Company’s involvement with Funds that are VIEs and not consolidated by the Company is generally limited to that of an investment manager and its investment in the unconsolidated VIE, if any. The Company’s investment in any unconsolidated VIE generally represents an insignificant interest of the Fund’s net assets and assets under management, such that the majority of the VIEs results are attributable to third parties. The Company’s exposure to risk in these entities is generally limited to any capital contribution it has made or is required to make and any earned but uncollected management fees. The Company has not issued any investment performance guarantees to these VIEs or their investors. The following information pertains to unconsolidated VIEs for which the Company holds a variable interest (in millions): June 30, December 31, Unconsolidated VIE assets $ 722.6 $ 795.5 Unconsolidated VIE liabilities $ 298.4 $ 323.6 Equity interests on the Condensed Consolidated Balance Sheets $ 4.2 $ 4.8 Maximum risk of loss (1) $ 4.2 $ 5.0

(2) The difference between the principal amounts and the carrying values of the senior notes in the table above reflects the unamortized debt issuance costs and discounts. (3) On January 18, 2022, the Company completed the full redemption of the $125 million aggregate principal amount outstanding of its 5.125% Senior Notes due August 1, 2031. As a result of this transaction, the Company recorded a $3.2 million loss on extinguishment of debt within the Condensed Consolidated Statements of Operations for the six months ended June 30, 2022. Revolving Credit Facility On March 7, 2022, the Company, Royal Bank of Canada, BMO Harris Bank, N.A., Goldman Sachs Bank USA, Morgan Stanley Bank, N.A., Bank of America N.A., the Bank of New York Mellon and Citibank, N.A., as an issuing bank and administrative agent (collectively, the “Lenders”), entered into a new revolving credit facility agreement (the “Acadian Credit Agreement”), which replaced the Company’s revolving credit facility dated as of August 20, 2019 (as amended by an amendment dated September 3, 2020 and an assignment and assumption and amendment agreement dated February 23, 2021, the “Original Credit Agreement”). The maturity date of this Original Credit Agreement was August 22, 2022, and the maturity date of the Acadian Credit Agreement is March 7, 2025. Borrowings under the Acadian Credit Agreement bear interest, at Acadian’s option, at the per annum rate equal to either (a) the greatest of (i) the prime rate, (ii) the federal funds effective rate plus 0.5% and (iii) the secured overnight financing rate for a one month period plus a credit spread adjustment of 0.10% (“Adjusted Term SOFR”) plus 1%, plus, in each case, an additional amount ranging from 0.5% to 1.0%, with such additional amount based on Acadian’s Leverage Ratio (as defined below) or (b) Adjusted Term SOFR for plus an additional amount ranging from 1.5% to 2.0%, with such additional amount based on Acadian’s Leverage Ratio. In addition, Acadian is charged a commitment fee based on the average daily unused portion of the revolving credit facility under the Acadian Credit Agreement at a per annum rate ranging from 0.25% to 0.375%, with such amount based on Acadian’s Leverage Ratio. Under the Acadian Credit Agreement, the ratio of Acadian’s third-party borrowings to Acadian’s trailing twelve months Adjusted EBITDA, as defined by the Acadian Credit Agreement (the “Leverage Ratio”), cannot exceed 2.5x and the Acadian interest coverage ratio must not be less than 4.0x.

Commitments and Contingencies

Commitments and Contingencies	6 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Operational commitments A number of our subsidiaries operate under regulatory authorities that require that they maintain minimum financial or capital requirements. Management is not aware of any violations of such financial requirements occurring during the period. Included in cash and cash equivalents is $1.5 million pertaining to the wind-down of BrightSphere Investment U.K., Ltd. Guaranty The Company entered into a guaranty for an office space security deposit in the amount of $2.5 million in January 2020. This represents the maximum potential amount of future (undiscounted) payments that the Company could be required to make under the guaranty in the event of default by the guaranteed parties. This guaranty expires in 2022. There are no liabilities recorded on the Condensed Consolidated Balance Sheet as of June 30, 2022 related to this guaranty. Litigation The Company is subject to claims, legal proceedings, and other contingencies in the ordinary course of its business activities. Each of these matters is subject to various uncertainties, and it is possible that some of these matters may be resolved in a manner unfavorable to the Company. The Company establishes accruals for matters for which the outcome is probable and can be reasonably estimated. If an insurance claim or other indemnification for a litigation accrual is available to the Company, the associated gain will not be recognized until all contingencies related to the gain have been resolved. As of June 30, 2022, there were no material accruals for claims, legal proceedings, or other contingencies. Indemnifications In the normal course of business, such as through agreements to enter into business combinations and divestitures of Affiliates, the Company enters into contracts that contain a variety of representations and warranties and which provide general indemnifications. The Company’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred. Foreign tax contingency The Company has clients in non-U.S. jurisdictions which require entities that are conducting certain business activities in such jurisdictions to collect and remit tax assessed on certain fees paid for goods and services provided. The Company does not believe this requirement is applicable based on its limited business activities in these jurisdictions. However, given the fact that uncertainty exists around the requirement, the Company has chosen to evaluate its potential exposure related to non-collection and remittance of these taxes. At June 30, 2022, management of the Company has estimated the potential maximum exposure and concluded that it is not material. No accrual for the potential exposure has been recorded as the probability of incurring any potential liability relating to this exposure is not probable at June 30, 2022. Considerations of credit risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash, cash equivalents, restricted cash and investments. The Company maintains cash and cash equivalents and short term investments with various financial institutions. These financial institutions are typically located in cities in which the Company and its Affiliates operate. For the Company and certain Affiliates, cash deposits at a financial institution may exceed Federal Deposit Insurance Corporation insurance limits. At June 30, 2022, approximately $20.6 million of the Company’s cash and cash equivalents were invested in money market funds. Additionally, the Company holds insurance policies which cover historical and future tax benefits relating to certain of its deferred tax assets. The insurers of the policies are considered a significant counterparty to the Company.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share is calculated by dividing net income attributable to controlling interests by the weighted-average number of shares of common stock outstanding. Diluted earnings per share is similar to basic earnings per share, but is adjusted for the effect of potentially issuable common stock, except when inclusion is antidilutive. The calculation of basic and diluted earnings per share of common stock is as follows (dollars in millions, except per share data): Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Numerator: Income from continuing operations attributable to controlling interests $ 28.6 $ 24.7 $ 52.4 $ 43.2 Income from discontinued operations attributable to controlling interests (Note 3) — 508.0 — 516.5 Net income attributable to common stock $ 28.6 $ 532.7 $ 52.4 $ 559.7 Denominator: Weighted-average shares of common stock outstanding—basic 41,425,555 79,351,567 42,690,683 79,335,650 Potential shares of common stock: Restricted stock units 6,935 23,323 8,523 29,472 Employee stock options 1,085,635 3,551,234 1,216,600 3,258,363 Weighted-average shares of common stock outstanding—diluted 42,518,125 82,926,124 43,915,806 82,623,485 Earnings per share of common stock attributable to controlling interests: Basic Continuing operations $ 0.69 $ 0.31 $ 1.23 $ 0.54 Discontinued operations — 6.40 — 6.51 Basic earnings per share of common stock attributable to controlling interests $ 0.69 $ 6.71 $ 1.23 $ 7.05 Diluted Continuing operations $ 0.67 $ 0.29 $ 1.19 $ 0.52 Discontinued operations — 6.13 — 6.25 Diluted earnings per share of common stock attributable to controlling interests $ 0.67 $ 6.42 $ 1.19 $ 6.77

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Management fees The Company’s management fees are a function of the fee rates the Affiliates charge to their clients, which are typically expressed in basis points, and the levels of the Company’s assets under management. The most significant driver of increases or decreases in this average fee rate is changes in the mix of the Company’s assets under management caused by net inflows or outflows in certain asset classes or disproportionate market movements. Performance fees The Company’s products subject to performance fees earn these fees upon exceeding high-water mark performance thresholds or outperforming a hurdle rate. Performance fees are recorded in revenues when the contractual performance criteria have been met and when it is probable that a significant reversal of revenue recognized will not occur in future reporting periods. Other revenue Included in other revenue are certain payroll and benefits costs and expenses paid on behalf of Funds by the Company’s Affiliates. In instances where a customer reimburses the Company for a cost paid on the customer’s behalf, the Company is acting as a principal and the reimbursement is accrued on a gross basis at cost as the corresponding reimbursable expenses are incurred. There was no revenue from expense reimbursements for the three and six months ended June 30, 2022. Revenue from expense reimbursements amounted to $1.2 million for the three months ended June 30, 2021. Revenue from expense reimbursements amounted to $2.2 million for the six months ended June 30, 2021. Revenue is recorded in other revenue in the Company’s Condensed Consolidated Statements of Operations. Other revenue may also consist of other miscellaneous revenue, consisting primarily of administration and consulting services. Disaggregation of management fee revenue The geographic disaggregation of management fee revenue for the three and six months ended June 30 (in millions) are presented below: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Quant & Solutions U.S. $ 71.2 $ 80.0 $ 148.2 $ 154.4 Non-U.S. 22.3 26.0 47.5 50.5 Other (1) U.S. — 4.1 — 7.8 Non-U.S. — 1.5 — 2.7 Management fee revenue $ 93.5 $ 111.6 $ 195.7 $ 215.4 (1) The Company’s previously divested Affiliates, Campbell Global and ICM, are included within the Other

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	Derivatives and Hedging Cash flow hedge In July 2015, the Company entered into a series of $300.0 million notional Treasury rate lock contracts which were designated and qualified as cash flow hedges. The Company documented its hedging strategy and risk management objective for this contract in anticipation of a future debt issuance. The Treasury rate lock contract eliminated the impact of fluctuations in the underlying benchmark interest rate for future forecasted debt issuances. The Company assessed the effectiveness of the hedging contract at inception and on a quarterly basis thereafter. The forecasted debt issuances occurred in July 2016 and the Treasury rate lock, which had an accumulated fair value of $(34.4) million, was settled. Refer to Note 7, Borrowings and Debt, for additional information on the debt issuances. As of June 30, 2022, the balance recorded in accumulated other comprehensive income (loss) was $(13.4) million, net of tax. This balance will be reclassified to earnings through interest expense over the life of the issued debt. The Company reclassified $0.8 million for each of the three months ended June 30, 2022 and 2021. Amounts of $3.0 million and $1.6 million have been reclassified for the six months ended June 30, 2022 and 2021, respectively. During the next twelve months the Company expects to reclassify approximately $3.3 million to interest expense.

Segments

Segment Reporting [Abstract]
Segments	Segments The Company has the following reportable segment: • Quant & Solutions —comprised of versatile, often highly-tailored strategies that leverage data and technology in a computational, factor-based investment process across a range of asset classes in developed and emerging markets, including global, non-U.S. and small-cap equities, as well as managed volatility, ESG, multi-asset, equity alternatives, and long/short strategies. This segment is comprised of the Company’s interest in Acadian. The corporate head office is included within the Other category, along with our previously disposed Affiliates, Campbell Global and ICM, for the three and six months ended June 30, 2021. The corporate head office expenses are not allocated to the Company’s business segment but the Chief Operating Decision Maker (“CODM”) does consider the cost structure of the corporate head office when evaluating the financial performance of the segment. Performance Measure The primary measure used by the CODM in measuring performance and allocating resources to the segments is Economic Net Income (“ENI”). The Company defines ENI for the segments as ENI revenue less (i) ENI operating expenses, (ii) variable compensation and (iii) key employee distributions. The ENI adjustments to U.S. GAAP include both reclassifications of U.S. GAAP revenue and expense items, as well as adjustments to U.S. GAAP results, primarily to exclude non-cash, non-economic expenses, or to reflect cash benefits not recognized under U.S. GAAP. This measure supplements and should be considered in addition to, and not in lieu of, the Condensed Consolidated Statements of Operations prepared in accordance with U.S. GAAP. The Company does not disclose total asset information for its reportable segment as the information is not reviewed by the CODM. ENI revenue includes management fees, performance fees and other revenue under U.S. GAAP, adjusted to include management fees paid to Affiliates by consolidated Funds and the Company’s share of earnings from equity-accounted Affiliate. ENI revenue is also adjusted to exclude the separate revenues recorded under U.S. GAAP for certain Fund expenses reimbursed to our Affiliates. ENI operating expenses include compensation and benefits, general and administrative expense, and depreciation and amortization under U.S. GAAP, adjusted to exclude non-cash expenses representing changes in the value of Affiliate equity and profit interests held by Affiliate key employees, goodwill impairment and amortization of acquired intangible assets, capital transaction costs, restructuring costs, and the separate expenses recorded under U.S. GAAP for certain Fund expenses reimbursed to Affiliates.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation These unaudited Condensed Consolidated Financial Statements reflect the historical balance sheets, statements of operations, comprehensive income, changes in stockholders’ equity and cash flows of the Company. Within these Condensed Consolidated Financial Statements, Paulson and its related entities, as defined above, are referred to as “related parties.” The Condensed Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). In the opinion of management, all normal and recurring adjustments considered necessary for a fair presentation of the Company’s Condensed Consolidated Financial Statements have been included. All dollar amounts, except per-share data in the text and tables herein, are stated in millions unless otherwise indicated. Transactions between the Company and its related parties are included in the Condensed Consolidated Financial Statements, however, material intercompany balances and transactions among the Company, its consolidated Affiliates and consolidated Funds are eliminated in consolidation. The Notes to the Condensed Consolidated Financial Statements are presented on a continuing operations basis unless otherwise noted. See Note 3, Discontinued Operations for additional information. Certain disclosures included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (annual report on Form 10-K) are not required to be included on an interim basis in the Company’s quarterly reports on Form 10-Q. The Company has condensed or omitted these disclosures. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K as filed with the Securities and Exchange Commission (“SEC”) on February 28, 2022. The Company’s significant accounting policies, which have been consistently applied, are summarized in those financial statements.
Use of estimates	Use of estimatesThe preparation of these Condensed Consolidated Financial Statements 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 period. Actual results could differ from such estimates, and the differences may be material to the Condensed Consolidated Financial Statements.
New accounting standards not yet adopted	New accounting standards not yet adopted The Company has considered all newly issued accounting guidance that is applicable to the Company’s operations and the preparation of the unaudited Condensed Consolidated Financial Statements, including those that have not yet been adopted. The Company does not believe that any such guidance has or will have a material effect on its Condensed Consolidated Financial Statements and related disclosures.
Variable interest entities (“VIEs”)	The Company, through its Affiliate, sponsors the formation of various entities considered to be VIEs. These VIEs are primarily Funds managed by the Company’s Affiliate and other partnership interests typically owned entirely by third party investors. Certain Funds may be capitalized with seed capital investments from the Company and may be owned partially by Affiliate key employees and/or individuals that own non-controlling interests in the Affiliate. The Company’s determination of whether it is the primary beneficiary of a Fund that is a VIE is based in part on an assessment of whether or not the Company and its related parties are exposed to more than an insignificant amount of the risks and rewards of the entity. Typically, the Fund’s investors are entitled to substantially all of the economics of these VIEs with the exception of the management fees and performance fees, if any, earned by the Company or any investment the Company has made into the Funds. The Company generally is not the primary beneficiary of Fund VIEs created to manage assets for clients unless the Company’s ownership interest, including interests of related parties, is substantial. The Company did not consolidate any funds that are VIEs as of June 30, 2022 and December 31, 2021. The Company’s involvement with Funds that are VIEs and not consolidated by the Company is generally limited to that of an investment manager and its investment in the unconsolidated VIE, if any. The Company’s investment in any unconsolidated VIE generally represents an insignificant interest of the Fund’s net assets and assets under management, such that the majority of the VIEs results are attributable to third parties. The Company’s exposure to risk in these entities is generally limited to any capital contribution it has made or is required to make and any earned but uncollected management fees. The Company has not issued any investment performance guarantees to these VIEs or their investors.

Fair Value Disclosures [Abstract]
Summary of the assets and liabilities that are measured at fair value on a recurring basis	The following table summarizes the Company’s assets that are measured at fair value on a recurring basis at June 30, 2022 (in millions): Quoted prices Significant Significant Uncategorized Total value, Assets (1) Investments in separate accounts (2) 4.0 — — — 4.0 Investments related to long-term incentive compensation plans (3) 40.9 — — — 40.9 Investments in unconsolidated Funds (4) — — — 4.2 4.2 Total fair value assets $ 44.9 $ — $ — $ 4.2 $ 49.1 The following table summarizes the Company’s assets that are measured at fair value on a recurring basis at December 31, 2021 (in millions): Quoted prices Significant Significant Uncategorized Total value December 31, 2021 Assets (1) Investments in separate accounts (2) 4.6 — — — 4.6 Investments related to long-term incentive compensation plans (3) 45.0 — — — 45.0 Investments in unconsolidated Funds (4) — — — 4.9 4.9 Total fair value assets $ 49.6 $ — $ — $ 4.9 $ 54.5 (1) Assets measured at fair value are comprised of financial investments managed by the Company's Affiliates. Equity securities, including common and preferred stock and short-term investment funds which are traded on a national securities exchange are stated at the last reported sales price on the day of valuation. To the extent these securities are actively traded and valuation adjustments are not applied, they are classified as Level I. The securities that trade in markets that are not considered to be active but are valued based on quoted market prices, dealer quotations or alternative pricing sources supported by observable inputs obtained by the Company from independent pricing services are classified as Level II. The Company obtains prices from independent pricing services that may utilize broker quotes, but generally the independent pricing services will use various other pricing techniques which take into account appropriate factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data. The Company has not made adjustments to the prices provided. If the pricing services are only able to (a) obtain a single broker quote or (b) utilize a pricing model, such securities are classified as Level III. If the pricing services are unable to provide prices, the Company attempts to obtain one or more broker quotes directly from a dealer or values such securities at the last bid price obtained. In either case, such securities are classified as Level III. The Company performs due diligence procedures over third party pricing vendors to understand their methodology and controls to support their use in the valuation process to ensure compliance with required accounting disclosures. (2) Investments in separate accounts of $4.0 million at June 30, 2022 consist of approximately 100% of equity securities and other investments. Investments in separate accounts of $4.6 million at December 31, 2021 consist of approximately 100% of equity securities and other investments. The Company values these using the published price of the underlying securities (classified as Level I) or quoted price supported by observable inputs as of the measurement date (classified as Level II). (3) Investments related to long-term incentive compensation plans of $40.9 million and $45.0 million at June 30, 2022 and December 31, 2021, respectively, were investments in publicly registered daily redeemable funds (some managed by Affiliates), which the Company has classified as trading securities and valued using the published price as of the measurement dates. Accordingly, the Company has classified these investments as Level I. (4) The uncategorized amounts of $4.2 million and $4.9 million at June 30, 2022 and December 31, 2021, respectively, relate to investments in unconsolidated Funds which consist primarily of investments in Funds and are valued using NAV which the Company relies on to determine their fair value as a practical expedient and has therefore not classified these investments in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to amounts presented in the Condensed Consolidated Balance Sheets. These unconsolidated Funds consist primarily of real estate investment Funds, UCITS and other investment vehicles. The NAVs that have been provided by investees have been derived from the fair values of the underlying investments as of the measurement dates. UCITS and other investment vehicles are not subject to redemption restrictions. The real estate investment Funds of $4.2 million and $4.8 million at June 30, 2022 and December 31, 2021, respectively, are subject to longer than quarterly redemption restrictions, and due to their nature, distributions are received only as cash flows are generated from underlying assets over the life of the Funds. The range of time over which the underlying assets are expected to be liquidated by the investees is approximately one year from June 30, 2022. The valuation process for the underlying real estate investments held by the real estate investment Funds begins with each property or loan being valued by the investment teams. The valuations are then reviewed and approved by the valuation committee, which consists of senior members of the portfolio management, acquisitions, and research teams. For certain properties and loans, the valuation process may also include a valuation by independent appraisers. In connection with this process, changes in fair value measurements from period to period are evaluated for reasonableness, considering items such as market rents, capitalization and discount rates, and general economic and market conditions.
