Business and Summary of Significant Accounting Policies | Business and Summary of Significant Accounting Policies (a) Organization and Nature of Operations Affiliated Managers Group, Inc. (“AMG” or the “Company”) is a global asset management company with equity investments in leading boutique investment management firms, referred to as “Affiliates.” AMG’s Affiliates provide investment management services globally to institutional clients, mutual funds and high net worth individuals. Each of AMG’s Affiliates operate through distinct entities, typically organized as limited liability companies or limited partnerships (or equivalent non-U.S. forms), which affords AMG the flexibility to design a separate operating agreement for each Affiliate. The operating agreements reflect the specific terms of AMG’s economic participation in the Affiliate (a “structured partnership interest”). AMG’s structured partnership interests consist primarily of structures through which AMG shares in the Affiliate’s revenue without regard to expenses. AMG’s structured partnership interests also include structures through which AMG shares in the Affiliate’s revenue less certain agreed-upon expenses. When AMG owns a majority of the equity interests in an Affiliate and shares in the Affiliate’s revenue without regard to expenses, a set percentage of revenue is allocated to fund operating expenses, including compensation (the “Operating Allocation”), while the remaining revenue (the “Owners’ Allocation”) is allocated to AMG and Affiliate management in proportion to their respective ownership interests. When AMG owns a minority of the equity interests in an Affiliate and shares in the Affiliate’s revenue without regard to expenses, AMG is allocated a set percentage of revenue, with the remaining revenue allocated to fund operating expenses and distributions to Affiliate management. When AMG’s structured partnership interest is calculated by reference to an Affiliate’s revenue less certain agreed upon expenses, whether AMG owns a majority or minority of the equity interests, AMG is allocated a set percentage of the Affiliate’s revenue net of the agreed categories of expenses. (b) Basis of Presentation and Use of Estimates The financial statements are prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”). All dollar amounts, except per share data in the text and tables herein, are stated in millions unless otherwise indicated. Certain reclassifications have been made to prior years’ financial statements to conform to the current year’s presentation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (c) Principles of Consolidation Investments in Affiliates The Company evaluates the risk, rewards, and significant terms of each of its Affiliate and other investments to determine the appropriate method of accounting. Majority-owned or otherwise controlled investments are consolidated and all material intercompany balances and transactions are eliminated. For its consolidated Affiliates, the portion of the Owners’ Allocation allocated to Affiliate management is included in Net income (non-controlling interests) in the Consolidated Statements of Income. Non-controlling interests on the Consolidated Balance Sheets include capital and undistributed Operating and Owners’ Allocation owned by Affiliate management of the consolidated Affiliates. The effect of any changes in the Company’s equity interests in its consolidated Affiliates resulting from the issuance or repurchase of an Affiliate’s equity by the Company or one of its Affiliates is included as a component of stockholders’ equity, net of the related income tax effect in the period of the change. The current redemption value of non-controlling interests has been presented as Redeemable non-controlling interests on the Consolidated Balance Sheets. AMG applies the equity method of accounting to investments where AMG does not hold a controlling equity interest but has the ability to exercise significant influence over operating and financial matters. In cases where AMG applies the equity method of accounting, it does not typically have an obligation to repurchase Affiliate equity interests. Other investments in which AMG owns less than a 20% interest and does not exercise significant influence are accounted for under the cost method. Under the cost method, income is recognized as dividends when, and if, declared. Affiliate-sponsored Investment Vehicles The Company’s Affiliates sponsor various investment vehicles where they also act as the investment advisor. Certain of these investment vehicles are variable interest entities (“VIEs”) while others are voting rights entities (“VREs”). VIEs are consolidated if the Affiliate is determined to be the primary beneficiary (i.e., if it absorbs a majority of the expected losses, or receives a majority of the expected residual returns). In determining whether the Affiliate is the primary beneficiary, both qualitative and quantitative factors (e.g., the voting rights of the equity holders, economic participation of all parties, including how fees are earned and paid, related party ownership, guarantees and implied relationships) are considered. VREs are consolidated if the Affiliate is the managing member or general partner of the investment vehicle unless unaffiliated investors have certain rights to remove the Affiliate from such role, have substantive participating rights or otherwise control the investment vehicle. (d) Cash and Cash Equivalents The Company considers all highly liquid investments, including money market mutual funds, with original maturities of three months or less to be cash equivalents. Cash equivalents are stated at cost, which approximates market value due to the short-term maturity of these investments. (e) Receivables The Company’s Affiliates earn advisory and performance fees, which are billed based on the terms of the related contracts. Billed but uncollected advisory and performance fees are presented within Receivables on the Consolidated Balance Sheets and are generally short-term in nature. Certain of the Company’s Affiliates in the United Kingdom act as an intermediary between clients and their sponsored funds. Normal settlement periods on transactions initiated by these clients result in unsettled fund share receivables and payables that are presented on a gross basis within Receivables and Payables and accrued liabilities on the Consolidated Balance Sheets. The gross presentation of these receivables and offsetting payables reflects the legal relationship between the underlying investor and the Company’s Affiliates. (f) Investments in Marketable Securities Investments in marketable securities are classified as either trading or available-for-sale and carried at fair value. Unrealized gains or losses on investments classified as available-for-sale are reported, net of tax, as a separate component of Accumulated other comprehensive income in Equity until realized when they are reported in Investment and other (income) expense. Realized and unrealized gains or losses related to trading securities are reported within Investment and other (income) expense in the period they occur on a specific identification basis. If a decline in the fair value of an available-for-sale investment is determined to be other than temporary, the carrying amount of the asset is reduced to its fair value, and the difference is charged to income in the period incurred. (g) Fair Value Measurements The Company determines the fair value of certain investment securities and other financial and non-financial assets and liabilities. Fair value is determined based on the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, utilizing a hierarchy of three different valuation techniques: Level 1 - Unadjusted quoted market prices for identical instruments in active markets; Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs, or significant value drivers, are observable; and Level 3 - Prices reflect the Company’s own assumptions concerning unobservable inputs to the valuation model. These inputs require significant management judgment and reflect the Company’s assumptions that market participants would use in pricing the asset or liability. (h) Fixed Assets Fixed assets are recorded at cost and depreciated using the straight-line method over their estimated useful lives. The estimated useful lives of office equipment and furniture and fixtures range from three to ten years . Computer software developed or obtained for internal use is amortized using the straight-line method over the estimated useful life of the software, generally three to seven years. Leasehold improvements are amortized over the shorter of their estimated useful lives or the term of the lease, and buildings are amortized over their expected useful lives. The costs of improvements that extend the life of a fixed asset are capitalized, while the cost of repairs and maintenance are expensed as incurred. Land is not depreciated. (i) Leases The Company and its Affiliates currently lease office space and equipment under various leasing arrangements. As these leases expire, it can be expected that in the normal course of business they will be renewed or replaced. Leases are classified as either capital leases or operating leases, as appropriate. Most lease agreements for office space that are classified as operating leases contain renewal options, rent escalation clauses or other inducements provided by the landlord. Rent expense is accrued to recognize lease escalation provisions and inducements provided by the landlord, if any, on a straight-line basis over the lease term. (j) Equity Investments in Affiliates For equity method investments, the Company’s share of the Affiliate’s revenue without regard to expenses or the Company’s share of the Affiliate’s revenue less certain agreed-upon expenses, net of any amortization of intangible assets related to the Company’s investment, is included in Income from equity method investments. The Company’s share of income taxes incurred directly by Affiliates accounted for under the equity method is recorded within income taxes because these taxes generally represent the Company’s share of the taxes incurred by the Affiliate. The Company periodically evaluates its equity method investments for impairment. In such impairment evaluations, the Company assesses if the fair value of the investment has declined below its carrying value for a period considered to be other than temporary. If the Company determines that a decline in fair value below the carrying value of the investment is other than temporary, then the reduction in carrying value would be recognized in Income from equity method investments in the Consolidated Statements of Income. (k) Acquired Client Relationships and Goodwill Each Affiliate in which the Company makes an investment has identifiable assets arising from contractual or other legal rights with their clients (“acquired client relationships”). In determining the value of acquired client relationships, the Company analyzes the net present value of these Affiliates’ existing client relationships based on a number of factors, including: the Affiliate’s historical and potential future operating performance; the Affiliate’s historical and potential future rates of attrition among existing clients; the stability and longevity of existing client relationships; the Affiliate’s recent, as well as long-term, investment performance; the characteristics of the firm’s products and investment styles; the stability and depth of the Affiliate’s management team; and the Affiliate’s history and perceived franchise or brand value. The Company has determined that certain of its mutual fund acquired client relationships meet the criteria to be considered indefinite-lived assets because the Company expects both the renewal of these contracts and the cash flows generated by these assets to continue indefinitely. Accordingly, the Company does not amortize these intangible assets, but instead reviews these assets annually or more frequently whenever events or circumstances occur indicating that the recorded indefinite-lived assets may be impaired. Each reporting period, the Company assesses whether events or circumstances have occurred that indicate that the indefinite life criteria are no longer met. If the indefinite life criteria are no longer met, the Company would assess whether the carrying value of the assets exceeds its fair value, an impairment loss would be recorded in an amount equal to any such excess and these assets would be reclassified to definite-lived. The expected useful lives of definite-lived acquired client relationships are determined based on an analysis of the historical and projected attrition rates of each Affiliate’s existing clients, and other factors that may influence the expected future economic benefit the Company will derive from the relationships. The expected lives of definite-lived acquired client relationships are analyzed annually or more frequently whenever events or circumstances have occurred that indicate the expected useful lives may no longer be appropriate. The Company tests for the possible impairment of indefinite and definite-lived intangible assets annually or more frequently whenever events or changes in circumstances indicate that the carrying amount of the asset is not recoverable. If such indicators exist, the Company compares the fair value of the asset to the carrying value of the asset. If the carrying value is greater than the fair value, an impairment loss would be recorded in Intangible amortization and impairments. Goodwill represents the future economic benefits arising from assets acquired in a business combination that are not individually identified and separately recognized, and is reported within the segments in which the Affiliate operates. Goodwill is not amortized, but is instead reviewed for impairment. The Company assesses goodwill for impairment at least annually, or more frequently whenever events or circumstances occur indicating that the recorded goodwill may be impaired. If the carrying amount of goodwill exceeds the fair value, an impairment loss would be recorded in Intangible amortization and impairments. (l) Issuance Costs Issuance costs related to Company’s senior bank debt are amortized over the remaining term of the credit facility and term loan. Costs incurred to issue debt are amortized over the shorter of the period to the first investor put or the Company’s estimate of the expected term of the security. Costs associated with financial instruments that are not required to be accounted for separately as derivative instruments are charged directly to stockholders’ equity. (m) Derivative Financial Instruments The Company may utilize financial instruments, specifically interest rate derivative contracts to hedge certain interest rate exposures. In entering into these contracts, the Company intends to offset cash flow gains and losses that occur on its existing debt obligations with cash flow gains and losses on the contracts hedging these obligations. From time to time, the Company’s Affiliates use foreign currency forward contracts to hedge the risk of currency exchange rate movements. In entering into these contracts, the Affiliates intend to offset cash flow gains and losses on projected foreign currency-denominated revenues and expenses as a result of variability in foreign currency exchange rates. The Company records derivatives on the balance sheet at fair value. If the Company’s derivatives qualify as cash flow hedges, the effective portion of the unrealized gain or loss is recorded in Accumulated other comprehensive income as a separate component of stockholders’ equity and reclassified into earnings when the hedged cash flows are recorded in earnings. Hedge effectiveness is generally measured by comparing the present value of the cumulative change in the expected future variable cash flows of the hedged contract with the present value of the cumulative change in the expected future variable cash flows of the hedged item. To the extent that the critical terms of the hedged item and the derivative are not identical, hedge ineffectiveness would be reported in Investment and other (income) expense. If the Company’s derivatives do not qualify as cash flow or fair value hedges, changes in the fair value of the derivatives are recognized as a gain or loss in Investment and other (income) expense. (n) Contingent Payment Arrangements The Company periodically enters into contingent payment arrangements in connection with its business combinations. In these arrangements, the Company agrees to pay additional consideration to the sellers to the extent that certain levels of revenue growth are achieved. For consolidated Affiliates, the Company estimates the fair value of these potential future obligations at the time a business combination is consummated and records a liability on its Consolidated Balance Sheet. The Company then accretes the obligation to its expected payment amount over the period until the arrangement is measured. If the Company’s expected payment amount subsequently changes, the obligation is reduced or increased in the current period resulting in a gain or loss, respectively. Both gains and losses resulting from changes to expected payments and the accretion of these obligations to their expected payment amounts are reflected within Imputed interest expense and contingent payment arrangements in the Company’s Consolidated Statements of Income. For Affiliates accounted for under the equity method, the Company records a liability when a payment becomes probable with a corresponding increase to the carrying value of the Affiliate. (o) Income Taxes The Company accounts for income taxes using the liability method. Under this method, deferred taxes are recognized for the expected future tax consequences of temporary differences between the book carrying amounts and tax bases of the Company’s assets and liabilities. Deferred tax liabilities are generally attributable to intangible assets, convertible securities and deferred income. Deferred tax assets are generally attributable to deferred compensation, state and foreign loss carryforwards, and the benefit of uncertain tax positions. Intangible-related deferred tax liabilities are not recorded on U.S. basis differences related to the Company’s foreign investments in corporate stock because of the permanent nature of the Company’s investments. In measuring the amount of deferred taxes each period, the Company must project the impact on its future tax payments of any reversal of deferred tax liabilities (which would increase the Company’s tax payments), and any use of its state and foreign loss carryforwards (which would decrease its tax payments). In forming these estimates, the Company uses enacted federal, state and foreign income tax rates and makes assumptions about the apportionment of future taxable income to jurisdictions in which the Company has operations. An increase or decrease in foreign, federal or state income tax rates could have a material impact on the Company’s deferred income tax liabilities and assets and would result in a current income tax charge or benefit. The Company recognizes the financial statement benefit of an uncertain tax position only after considering the probability that a tax authority would sustain the position in an examination. For tax positions meeting a “more-likely-than-not” threshold, the amount recognized in the financial statements is the benefit expected to be realized upon settlement with the tax authority. For tax positions not meeting the threshold, no financial statement benefit is recognized. The Company recognizes interest and other charges relating to unrecognized tax benefits as additional tax expense. The Company regularly assesses the need for valuation allowances on its deferred tax assets, which would reduce these assets to their recoverable amounts. In forming these estimates, the Company makes assumptions of future taxable income that may be generated to utilize these assets, which have limited lives. If the Company determines that these assets will be realized, the Company records an adjustment to the valuation allowance, which would decrease tax expense in the period such determination was made. Likewise, should the Company determine that it would be unable to realize additional amounts of deferred tax assets, an adjustment to the valuation allowance would be charged to tax expense in the period such determination was made. The Company operates in various locations outside the U.S. and generates earnings from its foreign subsidiaries. The Company does not recognize a provision for U.S. income taxes or a deferred income tax liability on undistributed foreign earnings that are indefinitely reinvested. (p) Foreign Currency Translation The assets and liabilities of Affiliates whose functional currency is not the U.S. dollar are translated into U.S. dollars using exchange rates in effect as of the balance sheet date. The revenue and expenses of these Affiliates are translated into U.S. dollars using average exchange rates for the relevant period. Because of the permanent nature of the Company’s investments, net translation exchange gains and losses are excluded from Net income and recorded in Other comprehensive income. Foreign currency transaction gains and losses are reflected in Investment and other (income) expense. (q) Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash investments. The Company maintains cash and cash equivalents, investments and, at times, certain financial instruments with various high credit-quality financial institutions. These financial institutions are typically located in countries in which AMG and its Affiliates operate. For AMG and certain Affiliates, cash deposits at a financial institution may exceed Federal Deposit Insurance Corporation insurance limits. (r) Revenue Recognition The Company’s consolidated revenue primarily represents advisory fees billed by Affiliates for managing the assets of clients. Asset-based advisory fees are recognized as services are rendered and are based upon a percentage of the value of client assets managed. Any fees collected in advance are deferred and recognized as income over the period earned. Performance-based advisory fees are generally assessed as a percentage of the investment performance realized on a client’s account, generally over an annual period. Performance-based advisory fees are recognized when they are earned (i.e., when they become billable to customers and are not subject to claw-back) based on the contractual terms of agreements and when collection is reasonably assured. Carried interest is recognized upon the earlier of the termination of the investment product or when the likelihood of claw-back is improbable. Also included in revenue are commissions earned by broker-dealers, recorded on a trade date basis, and other service fees recorded as earned. The Company’s Affiliates have contractual arrangements with third parties to provide certain distribution-related services. These third parties are primarily compensated based on the value of client assets over time. Distribution-related revenues are presented gross of any related expenses when the Affiliate is the principal in its role as primary obligor under its sales and distribution arrangements. Distribution-related expenses are presented within Selling, general and administrative expenses. (s) Earnings Per Share The calculation of basic earnings per share is based on the weighted average number of shares of the Company’s common stock outstanding during the period. Diluted earnings per share is similar to basic earnings per share, but adjusts for the dilutive effect of the potential issuance of incremental shares of the Company’s common stock. The Company had convertible securities outstanding during the periods presented and is required to apply the if-converted method to these securities in its calculation of diluted earnings per share. Under the if-converted method, shares that are issuable upon conversion are deemed outstanding, regardless of whether the securities are contractually convertible into the Company’s common stock at that time. For this calculation, the interest expense (net of tax) attributable to these dilutive securities is added back to Net income (controlling interest), reflecting the assumption that the securities have been converted. Issuable shares for these securities and related interest expense are excluded from the calculation if an assumed conversion would be anti-dilutive to diluted earnings per share. (t) Share-Based Compensation Plans The Company recognizes expenses for all share-based payments based on their grant date fair values over the requisite service period. The Company reports any tax benefits realized upon the exercise of stock options that are in excess of the expense recognized for reporting purposes as a financing activity in the Company’s Consolidated Statements of Cash Flows. If the tax benefit realized is less than the expense, the tax shortfall is recognized in stockholders’ equity. To the extent the expense exceeds available windfall tax benefits, it is recognized in the Consolidated Statements of Income. The Company was permitted to calculate its cumulative windfall tax benefits for the purposes of accounting for future tax shortfalls. The Company elected to apply the long-form method for determining the pool of windfall tax benefits. (u) Segment Information Management has assessed and determined that the Company operates in three business segments representing the Company’s three principal distribution channels: Institutional, Mutual Fund and High Net Worth, each of which has different client relationships. Revenue and income from equity method investments in the Institutional distribution channel is earned from relationships with public and private client entities, including foundations, endowments, sovereign wealth funds and retirement plans for corporations and municipalities. Revenue and income from equity method investments in the Mutual Fund distribution channel is earned from advisory or sub-advisory relationships with active return oriented mutual funds, UCITS and other retail products. Revenue and income from equity method investments in the High Net Worth distribution channel is earned from relationships with high net worth and ultra-high net worth individuals, families, trusts, foundations, endowments and retirement plans. In measuring Net income (controlling interest) by segment, the Company’s share of expenses incurred directly at Affiliates and AMG Funds is allocated to a particular segment pro rata to the revenue generated by the Affiliate and AMG Funds in such segment. All other operating and non-operating expenses not incurred directly by an Affiliate or AMG Funds are generally allocated to segments based on the relative contribution to earnings of the applicable Affiliate or AMG Funds in each segment. (v) Recent Accounting Developments In May 2014, the Financial Accounting Standards Board (the “FASB”) issued a final standard on revenue from contracts with customers. The new standard provides a comprehensive model for revenue recognition. The new standard is effective for interim and fiscal periods beginning after December 15, 2017. The Company is evaluating the impact of this standard on its Consolidated Financial Statements. In February 2015, the FASB issued a new standard that amended the current consolidation guidance. The new standard changes the analysis required to determine whether an entity is a variable interest entity and should be consolidated. The new standard is effective for interim and fiscal periods beginning after December 15, 2015. The Company is evaluating the impact of this new standard on its Consolidated Financial Statements. In April 2015, the FASB issued a new standard to reduce diversity in the presentation of debt issuance costs. The new standard requires debt issuance costs to be presented on the balance sheet as a deduction from the related debt. The new standard is effective for interim and fiscal periods beginning after December 15, 2015. The Company does not anticipate that this new standard will have a material impact on its Consolidated Financial Statements. In April 2015, the FASB issued a new standard amending the disclosure requirements for investments in certain entities that calculate net asset value per share. The new standard removes, from the fair value hierarchy, investments for which the net asset value is used as a practical measure of fair value. The new standard is effective for interim and fiscal periods beginning after December 15, 2015. The Company does not anticipate that this new standard will have a material impact on its Consolidated Financial Statements. In September 2015, the FASB issued a new standard requiring an acquirer to recognize and disclose adjustments to provisional purchase price allocations, performed in connection with business combinations, in the reporting period in which the adjustments are determined. The new standard is effective for interim and fiscal periods beginning after December 15, 2015. The Company is evaluating the impact of this new standard on its Consolidated Financial Statements. In January 2016, the FASB issued a new standard that changes the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. Under the new guidance, all equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) will generally be measured at fair value through earnings. The new standard is effective for interim and fiscal periods beginning after December 15, 2017. The Company is evaluating the impact of this new standard on its Consolidated Financial Statements. |
