SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Mar. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements are prepared in accordance with the generally accepted accounting principles in the United States (“GAAP”) for interim financial information and instructions to the Quarterly Report on Form 10-Q. The condensed consolidated financial statements, including these notes, are unaudited and exclude some of the disclosures required in annual financial statements. Management believes it has made all necessary adjustments so that the condensed consolidated financial statements are presented fairly and that estimates made in preparing its condensed consolidated financial statements are reasonable and prudent, and that all such adjustments are of a normal recurring nature. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2021 filed with the Securities and Exchange Commission (“SEC”). The unaudited condensed consolidated financial statements include the accounts and activities of the AOG entities, their consolidated subsidiaries and certain Consolidated Funds. All intercompany balances and transactions have been eliminated upon consolidation.
Reclassifications	The Company has reclassified certain prior period amounts to conform to the current year presentation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company considers the applicability and impact of all accounting standard updates (“ASU”) issued by the Financial Accounting Standards Board (“FASB”). ASUs not listed below were assessed and either determined to be not applicable or expected to have minimal impact on its unaudited condensed consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848). The amendments in this update provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848), to clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. An entity may elect to adopt the amendments in ASU 2020-04 and ASU 2021-01 at any time after March 12, 2020 but no later than December 31, 2022. The expedients and exceptions provided by the amendments do not apply to contract modifications and hedging relationships entered into or evaluated after December 31, 2022, except for hedging transactions as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The Company is currently evaluating the impact of this guidance on its unaudited condensed consolidated financial statements.
Fair Value Measurements	Fair Value Measurements GAAP establishes a hierarchical disclosure framework that prioritizes the inputs used in measuring financial instruments at fair value into three levels based on their market price observability. Market price observability is affected by a number of factors, including the type of instrument and the characteristics specific to the instrument. Financial instruments with readily available quoted prices from an active market or for which fair value can be measured based on actively quoted prices generally have a higher degree of market price observability and a lesser degree of judgment inherent in measuring fair value. Financial assets and liabilities measured and reported at fair value are classified as follows: •Level I—Quoted prices in active markets for identical instruments. •Level II—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in inactive markets; and model-derived valuations with directly or indirectly observable significant inputs. Level II inputs include prices in markets with few transactions, non-current prices, prices for which little public information exists or prices that vary substantially over time or among brokered market makers. Other inputs include interest rate, yield curve, volatility, prepayment risk, loss severity, credit risk and default rate. •Level III—Valuations that rely on one or more significant unobservable inputs. These inputs reflect the Company’s assessment of the assumptions that market participants would use to value the instrument based on the best information available. In some instances, an instrument may fall into more than one level of the fair value hierarchy. In such instances, the instrument’s level within the fair value hierarchy is based on the lowest of the three levels (with Level III being the lowest) that is significant to the fair value measurement. The Company’s assessment of the significance of an input requires judgment and considers factors specific to the instrument. The Company accounts for the transfer of assets into or out of each fair value hierarchy level as of the beginning of the reporting period.
