SEGMENT REPORTING | SEGMENT REPORTING The Company operates through its three distinct operating segments. In 2018, the Company reclassified certain expenses from OMG to its operating segments. The Company has modified historical results to conform with its current presentation. The Company’s three operating segments are: Credit Group: The Company’s Credit Group is a leading manager of credit strategies across the non-investment grade credit universe in the U.S. and Europe, with approximately $95.9 billion of AUM and 156 funds as of December 31, 2018 . The Credit Group offers a range of credit strategies across the liquid and illiquid spectrum, including syndicated loans, high yield bonds, credit opportunities, alternative credit investments and U.S. and European direct lending. The Credit Group provides solutions for traditional fixed income investors seeking to access the syndicated loans and high yield bond markets and capitalizes on opportunities across traded corporate credit. It additionally provides investors access to directly originated fixed and floating rate credit assets and the ability to capitalize on illiquidity premiums across the credit spectrum. The Credit Group’s syndicated loans strategy focuses on liquid, traded non-investment grade secured loans to corporate borrowers. The high yield bond strategy seeks to deliver a diversified portfolio of liquid, traded non-investment grade corporate bonds, including secured, unsecured and subordinated debt instruments. Credit opportunities is a “go anywhere” strategy seeking to capitalize on market inefficiencies and relative value opportunities across the capital structure. The alternative credit strategy seeks investment opportunities that fall outside of traditional, well-defined markets such as corporate debt, real estate and private equity. Alternative credit investments include certain structural features designed to protect value and minimize loss such as asset security, seniority, covenants, and cash flow prioritization. These investments include asset-backed securities, specialty assets, real assets, and structured credit. The Company has one of the largest self-originating direct lending platforms in the U.S. and European middle markets, providing one-stop financing solutions for small-to-medium sized companies, which the Company believes are increasingly underserved by traditional lenders. The Company provides investors access to these capabilities through several vehicles, including commingled funds, separately managed accounts and a publicly traded vehicle. The Credit Group conducts its U.S. lending activities primarily through ARCC, the largest business development company as of December 31, 2018 , by both market capitalization and total assets. In addition, the Credit Group manages a commercial finance business that provides asset-based and cash flow loans to small and middle-market companies, as well as asset-based facilities to specialty finance companies. The Credit Group’s European direct lending platform is one of the most significant participants in the European middle-market, focusing on self-originated investments in illiquid middle-market credits. Private Equity Group: The Company’s Private Equity Group has approximately $23.5 billion of AUM as of December 31, 2018 , broadly categorizing its investment strategies as corporate private equity, infrastructure and power, special opportunities and energy opportunities. As of December 31, 2018 , the group managed five corporate private equity commingled funds focused on North America and Europe and three focused on greater China, five commingled funds and six related co-investment vehicles focused on infrastructure and power, two commingled special opportunities funds and the Company's first energy opportunities fund. In its North American and European flexible capital strategy, the Company targets opportunistic majority or shared-control investments in businesses with strong franchises and attractive growth opportunities in North America and Europe. The infrastructure and power strategy targets infrastructure-related assets across the power generation, transmission, midstream sectors and renewables seeking attractive risk-adjusted equity returns with current cash flow and capital appreciation. The special opportunities strategy seeks to invest opportunistically across a broad spectrum of distressed or mispriced investments, including corporate debt, rescue capital, private asset-backed investments, post-reorganization securities and non-performing portfolios. The energy opportunities strategy targets investments in the energy industry where its flexible capital can provide attractive risk-adjusted returns while mitigating commodity risk. Real Estate Group: The Company’s Real Estate Group manages comprehensive equity and debt strategies, with approximately $11.3 billion of AUM across 43 funds as of December 31, 2018 . Real Estate equity strategies focus on applying hands-on value creation initiatives to mismanaged and capital-starved assets, as well as new development, ultimately selling stabilized assets back into the market. The Real Estate Group manages both a value-add strategy and an opportunistic strategy. The value-add strategy seeks to create value by buying assets at attractive valuations and through active asset management of income-producing properties across the U.S. and Western Europe. The opportunistic strategy focuses on manufacturing core assets through development, redevelopment and fixing distressed capital structures across major properties in the U.S. and Europe. The Company’s debt strategies leverage the Real Estate Group’s diverse sources of capital to directly originate and manage commercial mortgage investments on properties that range from stabilized to requiring hands-on value creation. In addition to managing private debt funds, the Real Estate Group makes debt investments through a publicly traded commercial mortgage REIT, ACRE. The Company has an OMG that consists of shared resource groups to support the Company’s operating segments by providing infrastructure and administrative support in the areas of accounting/finance, operations, information technology, strategy and relationship management, legal, compliance and human resources. Additionally, the OMG provides services to certain of the Company’s investment companies and partnerships, which reimburse the OMG for expenses equal to the costs of services provided. The OMG’s expenses are not allocated to the Company’s three reportable segments but the Company does consider the cost structure of the OMG when evaluating its financial performance. Non-GAAP Measures: These measures supplement and should be considered in addition to, and not in lieu of, the Consolidated Statements of Operations prepared in accordance with GAAP. Fee related earnings (“FRE”), a non-GAAP measure, is used to assess core operating performance by determining whether recurring revenue, primarily consisting of management fees, is sufficient to cover operating expenses and to generate profits. FRE differs from income before taxes computed in accordance with GAAP as it excludes performance income, performance related compensation, investment income from the Consolidated Funds and non-consolidated funds and certain other items that the Company believes are not indicative of its core operating performance. Realized income (“RI”), a non-GAAP measure, is an operating metric used by management to evaluate performance of the business based on operating performance and the contribution of each of the business segments to that performance, while removing the fluctuations of unrealized income and expenses, which may or may not be eventually realized at the levels presented and whose realizations depend more on future outcomes than current business operations. RI differs from net income by excluding (a) income tax expense, (b) operating results of our Consolidated Funds, (c) depreciation and amortization expense, (d) the effects of changes arising from corporate actions, (e) unrealized gains and losses related to performance income and investment performance and (f) certain other items that we believe are not indicative of our operating performance. Changes arising from corporate actions include equity-based compensation expenses, the amortization of intangible assets, transaction costs associated with mergers, acquisitions and capital transactions, underwriting costs and expenses incurred in connection with corporate reorganization. Beginning in 2018, placement fees are no longer excluded from RI but are amortized to match the period over which management fees are recognized. Prior to the introduction of RI, management used distributable earnings for this evaluation. Management believes RI is a more appropriate metric to evaluate the Company's current business operations. Management makes operating decisions and assesses the performance of each of the Company’s business segments based on financial and operating metrics and other data that is presented before giving effect to the consolidation of any of the Consolidated Funds. Consequently, all segment data excludes the assets, liabilities and operating results related to the Consolidated Funds and non‑consolidated funds.
