Basis of Presentation and Significant Accounting Policies | The Company’s significant accounting policies are as follows: Basis of presentation These unaudited Condensed Consolidated Financial Statements reflect the historical balance sheets; statements of operations and of comprehensive income; statements of changes in shareholders’ equity; and statements of cash flows of the Company. Within these Condensed Consolidated Financial Statements, entities that are part of the Parent’s consolidated results, but are not part of OMAM, as defined above, are referred to as “related parties.” On October 15, 2014, the Company completed the initial public offering (the “Offering”) by its Parent of 22,000,000 ordinary shares of the Company pursuant to the Securities Act of 1933, as amended. Additionally, the underwriters in the Offering exercised a portion of their overallotment option and purchased an additional 2,231,375 shares of the Company from the Parent. On June 22, 2015, the Company completed a secondary public offering by its Parent of 13,300,000 ordinary shares of the Company pursuant to the Securities Act of 1933, as amended. Additionally, the underwriters in the secondary public offering exercised their full overallotment option and purchased an additional 1,995,000 shares of the Company from the Parent. The Condensed Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). 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 the Parent are included in the Condensed Consolidated Financial Statements, however material intercompany balances and transactions among the Company and its consolidated Affiliates are eliminated in consolidation. 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, 2015 included in the Company’s Annual Report on Form 10-K as filed with the Securities and Exchange Commission (“SEC”) on March 15, 2016. The Company’s significant accounting policies, which have been consistently applied, are summarized in those Financial Statements. Consolidation Affiliates The Company evaluates each of its Affiliate and other operating entities to determine the appropriate method of accounting. Generally, majority-owned entities or otherwise controlled investments in which the Company holds a controlling financial interest as the principal shareholder, managing member, or general partner are consolidated. Funds In evaluating whether or not a legal entity must be consolidated, the Company determines if such entity is a variable interest entity (“VIE”) or a voting interest entity (“VOE”). A VOE is considered an entity in which (i) the total equity investment at risk is sufficient to enable the entity to finance its activities independently and (ii) the equity holders at risk have the obligation to absorb losses, the right to receive residual returns, and the right to direct the activities of the entity that most significantly impact the entity’s economic performance. A VIE is an entity that lacks one or more of the characteristics of a VOE. Assessing whether an entity is a VIE or VOE involves judgment and analysis. Factors considered in this assessment include the entity’s legal organization, the entity’s capital structure and equity ownership and any related party or de facto agent implications of the Company’s involvement with the entity. Investments that are determined to be VIEs are consolidated if the Company or a consolidated Affiliate is the primary beneficiary of the investment. VOEs are typically consolidated if the Company holds the majority voting interest or otherwise controls the entity. In the normal course of business, the Company’s Affiliates sponsor and manage certain investment vehicles (the “Funds”). The Company assesses consolidation requirements with respect to its Funds pursuant to Accounting Standards Codification (“ASC”) Topic 810, Consolidation, as amended by Accounting Standards Update 2015-02, Consolidation: Amendments to the Consolidation Analysis ("ASU 2015-02") relating to the consolidation of VIEs. In evaluating whether the Company is the primary beneficiary, the Company evaluates its economic interests in the entity held either directly by the Company or indirectly through related parties. For VIEs that are investment companies subject to ASU 2010-10, the primary beneficiary of the VIE is generally the variable interest holder that absorbs a majority of the expected losses of the VIE, receives a majority of the expected residual returns of the VIE, or both. 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 primary beneficiary of a VIE is defined as the variable interest holder that has a controlling financial interest. A controlling financial interest is defined as (i) the power to direct the activities of the VIE that most significantly impacts its economic performance and (ii) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. If no single party satisfies both criteria, but the Company and its related parties satisfy the criteria on a combined basis, then the primary beneficiary is the entity out of the related party group that is most closely associated to the VIE. The consolidation analysis can generally be performed qualitatively, however, if it is not readily apparent that the Company is not the primary beneficiary, a quantitative analysis may also be performed. The Company consolidates VOEs when it has control over significant operating, financial and investing decisions of the entity or holds the majority voting interest. For VOEs organized as limited partnerships or as an entity with governance structures similar to a limited partnership (e.g., limited liability company with a managing member), the Company consolidates an entity when it holds the controlling general partnership interest and the limited partners do not hold substantive participating rights or rights to remove and replace the general partner or rights that could provide the limited partners with the ability to impact the ongoing governance and operating activities of the entity. Upon the occurrence of certain events (such as contributions and redemptions, either by the Company, its Affiliates, or third parties, or amendments to the governing documents of the Company’s investees or sponsored Funds) management reviews and reconsiders its previous conclusion regarding the status of an entity as a VIE or a VOE. Additionally, management continually reconsiders whether the Company is deemed to be a VIE’s primary beneficiary who consolidates such entity. As of March 31, 2016 , there were no Funds which were consolidated pursuant to ASU 2015-02. Derivatives and Hedging The Company may utilize derivative financial instruments to hedge the risk of movement of interest rates and foreign currency on financial assets and liabilities. These derivative financial instruments may or may not qualify as hedges for accounting purposes. The Company records all derivative financial instruments as either assets or liabilities on its Consolidated Balance Sheets and measures these instruments at fair value. For a derivative financial instrument that qualifies as a hedge for accounting purposes and is designated as a hedging instrument, the effective portion of the derivative’s gain or loss is initially reported as a component of other comprehensive income (loss) and subsequently reclassified into earnings over the life of the hedge. The ineffective portion of the gain or loss is reported in earnings immediately. 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 significantly from those estimates. |
