| Accounting Pronouncements Recently Adopted and Pending Accounting Pronouncements | Accounting Pronouncements Recently Adopted Revenue Recognition. On January 1, 2018 th e company adopted Accounting Standards Update 2014-09, “Revenue from Contracts with Customers” (ASU 2014-09), which revised revenue accounting rules through the creation of Accounting Standards Codification Topic 606 (ASC 606) and expanded the disclosure requirements. The company adopted ASU 2014-09 on January 1, 2018 using the modified retrospective transition method applied to contracts that were not complete as of that date. Under this method, entities are required to report any effect from adoption as a cumulative effect adjustment to retained earnings at the adoption date. The adoption of the standard did not have an effect on opening retained earnings, net income or earnings per share measures. The impact of ASU 2014-09 on the timing of recognition of performance fee revenues may result in future performance fees being recognized earlier under ASU 2014-09, but this will depend on the terms and conditions in the relevant agreement. The application of the new principal versus agent guidance in ASU 2014-09 resulted in presentation changes in the Consolidated Statements of Income whereby certain costs are now reported on a gross basis, when Invesco is acting as principal, and reported on a net basis, when Invesco is acting as an agent. In accordance with the ASU 2014-09 requirements, the disclosure of the impact of adoption on the Consolidated Statements of Income was as follows (in millions): $ in millions Year ended December 31, 2018 Condensed Consolidated Statements of Income As Reported Adjustments Related to Adoption of Balances Without Adoption of Operating revenues: Investment management fees 4,082.3 205.9 4,288.2 Service and distribution fees 968.5 (127.2 ) 841.3 Performance fees 56.9 — 56.9 Other 206.4 (142.1 ) 64.3 Total operating revenues 5,314.1 (63.4 ) 5,250.7 Operating expenses: Third-party distribution, service and advisory 1,608.2 (82.0 ) 1,526.2 Employee compensation 1,494.4 — 1,494.4 Marketing 134.8 — 134.8 Property, office and technology 410.5 — 410.5 General and administrative 324.4 18.6 343.0 Transaction, integration, and restructuring 136.9 — 136.9 Total operating expenses 4,109.2 (63.4 ) 4,045.8 Operating income 1,204.9 — 1,204.9 The opening and closing balance of deferred carried interest liabilities for the year ended December 31, 2018 was $60.4 million and $61.3 million , respectively. During the year ended December 31, 2018 , no performance fee revenue was recognized that was included in the deferred carried interest liability balance at the beginning of the period. Financial Instruments. On January 1, 2018, the company adopted Accounting Standards Update 2016-01, "Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities" (ASU 2016-01). Under the new standard, all equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) will generally be measured at fair value with any changes recognized in earnings. ASU 2016-01 required a modified retrospective approach to adoption. Accumulated gains of $3.2 million were reclassified into retained earnings at adoption date. With effect from the adoption of ASU 2016-01, seed money, investments held to settle the company's deferred compensation plan liabilities, and other equity securities are no longer categorized as trading investments or available-for-sale investments but instead are referred to as "equity investments," and all gains or losses arising from changes in the fair value of these equity investments will be included in income. Prior period balances have been conformed to be presented as "equity investments," however the prior period treatment of gains or losses arising from changes in the fair value of the investments was retained. As ASU 2016-01 required a modified retrospective approach to adoption, available-for-sale seed money balances of $69.3 million at December 31, 2017 are presented as equity investments to conform to the current period presentation of seed money. Statement of Cash Flows. On January 1, 2018, the company adopted Accounting Standards Update 2016-15, "Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments" (ASU 2016-15), which clarified how certain cash receipts and cash payments are classified and presented on the Statement of Cash Flows, including distributions from equity method investees. The amendments require a retrospective approach to adoption. As a result of adopting this standard, $13.3 million was reclassified from net cash provided by/(used in) investing activities to net cash provided by/(used in) operating activities for the year ended December 31, 2017 . On January 1, 2018, the company adopted Accounting Standards Update 2016-18, “Statement of Cash Flows: Restricted Cash” (ASU 2016-18). The standard requires the inclusion of restricted cash within cash and cash equivalents when reconciling the beginning and ending cash and cash equivalents balances on the statements of cash flows. ASU 2016-18 requires a retrospective approach to adoption. Accordingly, changes in CIP cash of $226.2 million and ($509.4) million for the years ended December 31, 2017 and December 31, 2016 , respectively, are no longer presented as a component of the company's cash provided by operations as they were reported in the Form 10-K for the years ended December 31, 2017 and December 31, 2016 . These changes in CIP cash now form part of the reconciliation of corporate cash and CIP cash at the end of the Consolidated Statements of Cash Flows for the year ended December 31, 2018 . The adoption of this standard does not impact corporate cash and cash equivalents. Pension Costs. On January 1, 2018, the company adopted Accounting Standards Update 2017-07, “Compensation-Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (ASU 2017-07). The amendments require that the service cost component of net periodic pension costs be recorded within employee compensation expense and the other components of net benefit cost be recorded in other gains and losses, net in the Consolidated Statements of Income. The company utilized a practical expedient that permits an employer to use the amounts disclosed in its pension plan footnote for the prior comparative periods as the estimation basis for applying the retrospective presentation. The application of the new rules results in the reclassification of the non-service cost components of the pension costs/(benefit) to other gains and losses, net, and has no impact to net income. For the year ended December 31, 2017 , the reclassification increased operating income by $2.0 million , respectively, with a corresponding decrease to other gains and losses, net. For the year ended December 31, 2016 the reclassification decreased operating income by $24.0 million with a corresponding increase to other gains and losses, net. Pending Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update 2016-02, “Leases” (ASU 2016-02). The standard requires that lessees recognize lease assets and lease liabilities on the balance sheet for all leases with a lease term of greater than 12 months. ASU 2016-02 is effective for fiscal years and interim periods within those years beginning after December 15, 2018 and requires a modified retrospective approach to adoption. In July 2018, the FASB issued Accounting Standards Update 2018-11, “Leases: Targeted Improvements” (ASU 2018-11) which provided an additional, optional transition method related to implementing the new leases standard. ASU 2018-11 provides that companies can initially apply the new leases standard at adoption and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The company has decided to adopt the leases standard under this optional transition method on January 1, 2019 along with certain other practical expedients allowed during implementation. The company has undertaken a detailed review of its lease arrangements and anticipates that it will record a right-of-use asset of approximately $200.9 million and lease liability of approximately $251.5 million , primarily related to real estate leases, as a result of the adoption of ASU 2016-02. The company is implementing a lease accounting software tool to assist in the accounting for lease arrangements under the new accounting rules and has abstracted lease contract data as inputs into the lease accounting tool. As of the date of this Report, the company is completing its data validation and detailed testing of the outputs of the software tool. In June 2016, the FASB issued Accounting Standards Update 2016-13, “Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments” (ASU 2016-13). ASU 2016-13 amends guidance on reporting credit losses for assets measured at amortized cost and available for sale securities. ASU 2016-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019 and requires a modified retrospective approach to adoption. Early adoption in fiscal years, and interim periods within those years, beginning after December 15, 2018 is permitted. The company is currently evaluating the potential impact of this standard. In January 2017, the FASB issued Accounting Standards Update 2017-04, “Intangibles-Goodwill and Other: Simplifying the Test for Goodwill Impairment” (ASU 2017-04). The standard simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under the amendments of ASU 2017-04, an entity should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity will recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, but the loss cannot exceed the total amount of goodwill allocated to the reporting unit. ASU 2017-04 is effective for fiscal years and interim periods within those years beginning after December 15, 2019. The amendments require a prospective approach to adoption and early adoption is permitted for interim or annual goodwill impairment tests. The company intends to adopt the ASU 2017-04 on January 1, 2020 and apply the new standard for goodwill impairment testing beginning in fiscal year 2020. In August 2018, the FASB issued Accounting Standards Update 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract” (ASU 2018-15). The standard update aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019 and interim periods within those years and early adoption is permitted. The amendments allow either a retrospective or prospective approach to all implementation costs incurred after adoption. The company does not anticipate a material impact upon the adoption of this amendment. |
| Basis of Accounting and Consolidation | Basis of Accounting and Consolidation The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States and with rules and regulations of the Securities and Exchange Commission and consolidate the financial statements of the Parent and all of its controlled subsidiaries. In the opinion of management, the Consolidated Financial Statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for the fair presentation of the financial condition and results of operations for the periods presented. All significant intercompany transactions, balances, revenues and expenses are eliminated upon consolidation. The company provides investment management services to, and has transactions with, various retail mutual funds and similar entities, private equity funds, real estate funds, fund-of-funds, collateralized loan obligations (CLOs), and other investment products sponsored by the company in the normal course of business for the investment of client assets. The company serves as the investment manager, making day-to-day investment decisions concerning the assets of these products. In addition to consolidating the financial statements of the Parent and all of its controlled subsidiaries, the Consolidated Financial Statements include the consolidation of certain investment products (Consolidated Investment Products or CIP) that meet the definition of either a voting rights entity (VOE), if the company is deemed to have a controlling financial interest in the fund, or a variable interest entity (VIE), if the company has been deemed to be the primary beneficiary of the fund. Certain of these investment products, typically CLOs, funds that are structured as partnership entities (such as private equity funds, real estate funds, and fund-of-funds), and certain non-U.S. mutual funds, are considered, for accounting and consolidation analysis purposes, to be VIEs if the VIE criteria are met. A VIE, in the context of the company and its managed funds, is a fund that does not have sufficient equity to finance its operations without additional subordinated financial support, or a fund for which the risks and rewards of ownership are not directly linked to voting interests. If the company is deemed to have the power to direct the activities of the fund that most significantly impact the fund's economic performance, and the obligation to absorb losses/right to receive benefits from the fund that could potentially be significant to the fund, then the company is deemed to be the fund's primary beneficiary and is required to consolidate the fund. The company's economic risk with respect to each investment in a CIP is limited to its equity ownership and any uncollected management and performance fees. See Note 19 , "Consolidated Investment Products," for additional information regarding the impact of CIP. Consolidation Analysis The company inventories its funds by vehicle type on a quarterly basis. The company assesses modifications to existing funds on an ongoing basis to determine if a significant reconsideration event has occurred. The consolidation analysis includes a detailed review of the terms of the fund's governing documents and a comparison of the significant terms against the consolidation criteria in ASC Topic 810, including a determination of whether the fund is a VIE or a VOE. Seed money and co-investments in managed funds in which the company has determined that it is the primary beneficiary or in which the company has a controlling financial interest are consolidated if the impact of doing so is deemed material. Otherwise, these investments are accounted for as described in the “Investments” accounting policy below. Upon consolidation of an investment product, the company's gain or loss on its investment (before consolidation) eliminates with the company's share of the offsetting loss or gain in the fund. Upon consolidation of directly held CLOs, the company's and the funds' accounting policies are effectively aligned, resulting in the reclassification of the company's gain or loss (representing the changes in the market value of the company's holding in the consolidated fund) from other comprehensive income into other gains/losses. The net impact from consolidation of funds previously carried as available-for-sale investments to net income attributable to Invesco Ltd. in each period primarily represents the changes in the value of the company's holdings in its consolidated CLOs. Consolidation of CLOs A significant portion of VIEs are CLOs. CLOs are investment vehicles created for the sole purpose of issuing collateralized loan instruments that offer investors the opportunity for returns that vary with the risk level of their investment. The notes issued by the CLOs are backed by diversified collateral asset portfolios consisting primarily of loans or structured debt. For managing the collateral of the CLO entities, the company earns investment management fees, including in some cases subordinated management fees, as well as contingent performance fees. The company has invested in certain of the entities, generally taking a portion of the unrated, junior subordinated position. The company's investments in CLOs are generally subordinated to other interests in the entities and entitle the company and other subordinated tranche investors to receive the residual cash flows, if any, from the entities. The company's subordinated interest can take the form of (1) subordinated notes, (2) income notes or (3) preference/preferred shares. The company has determined that, although the junior tranches have certain characteristics of equity, they should be accounted for and disclosed as debt on the company's Consolidated Balance Sheets, as the subordinated and income notes have a stated maturity indicating a date for which they are mandatorily redeemable. The preference shares are also classified as debt, as redemption is required only upon liquidation or termination of the CLO and not of the company. The company determined that it was the primary beneficiary of certain CLOs, as it has the power to direct the activities of the CLOs that most significantly impact the CLOs' economic performance, and the obligation to absorb losses/right to receive benefits from the CLOs that could potentially be significant to the CLOs. The primary beneficiary assessment includes an analysis of the rights of the company in its capacity as investment manager. In some CLOs, the company's role as investment manager provides that the company contractually has the power, as defined in ASC Topic 810, to direct the activities of the CLOs that most significantly impact the CLOs' economic performance, such as managing the collateral portfolio and the CLOs' credit risk. In other CLOs, the company determined that it does not have this power in its role as investment manager due to certain rights held by other investors in the products or restrictions that limit the company's ability to manage the collateral portfolio and its credit risk. Additionally, the primary beneficiary assessment includes an analysis of the company's rights to receive benefits and obligations to absorb losses associated with its first loss position and management/performance fees. The company has elected the fair value option under ASC Topic 825-10-25 to measure the assets of all consolidated CLOs at fair value. All of the investments held by VIEs are presented at fair value in the company's Consolidated Balance Sheets at December 31, 2018 and 2017 . The notes issued by consolidated CLOs are measured under the measurement alternative discussed in ASU 2014-13, "Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity," which requires that the reporting entity measure both the financial assets and the fair value of the financial liabilities of the CLO using the more observable of the fair value of the financial assets and the fair value of the financial liabilities. The company’s earnings from consolidated CLOs reflect changes in fair value of its own economic interests in the CLOs. Gains or losses on assets and liabilities of the CLOs are not attributed to noncontrolling interests but are offset in other gains/(losses) of CIP. Consolidation of Private Equity, Real Estate, and Fund-of-Funds The company also consolidates certain private equity funds and from time to time real estate funds that are structured as partnerships in which the company is the general partner receiving a management and/or performance fee. Private equity investments made by the underlying funds consist of direct investments in, or fund investments in other private equity funds that hold direct investments in, equity or debt securities of operating companies that are generally not initially publicly traded. Private equity funds are considered investment companies and are therefore accounted for under ASC Topic 946, “Financial Services - Investment Companies.” The company has retained the specialized industry accounting principles of these investment products in its Consolidated Financial Statements. See Note 19 , “Consolidated Investment Products,” for additional details. Consolidation basis The Consolidated Financial Statements have been prepared primarily on the historical cost basis; however, certain items are presented using other bases such as fair value, where such treatment is required or voluntarily elected, as discussed above. The financial statements of subsidiaries, with the exception of certain CIP, are prepared for the same reporting period as the Parent and use consistent accounting policies, which, where applicable, have been adjusted to U.S. GAAP from local generally accepted accounting principles or reporting regulations. The financial information of certain CIP is included in the company's Consolidated Financial Statements on a one -month or a three -month lag based upon the availability of fund financial information. Noncontrolling interests in consolidated entities represents the interests in certain entities consolidated by the company either because the company has control over the entity or has determined that it is the primary beneficiary, but of which the company does not own all of the entity's equity. To the extent that noncontrolling interests represent equity which is redeemable or convertible for cash or other assets at the option of the equity holder, these are deemed to represent temporary equity, and are classified as equity attributable to redeemable noncontrolling interests in the Consolidated Balance Sheets. Nonredeemable noncontrolling interests are classified as a component of permanent equity. |
| Use of Estimates | Use of Estimates In preparing the Consolidated Financial Statements, management is required to make estimates and assumptions that affect reported revenues, expenses, assets, liabilities, and disclosure of contingent liabilities. The primary estimates and assumptions made relate to goodwill and intangible impairment, certain investments which are carried at fair value, post-employment benefit plan obligations, and taxes. Additionally, estimation is involved when determining investment and debt valuation for certain CIP; however, changes in the fair values of these amounts are largely offset by noncontrolling interests. Use of available information and application of judgment are inherent in the formation of estimates. Actual results in the future could differ from such estimates and the differences may be material to the Consolidated Financial Statements. |
| Reclassifications | Reclassifications During the fourth quarter of 2018, the company added a new U.S. GAAP income statement line item, "Transaction, integration and restructuring." This line item includes transaction-related costs for acquisitions, as well as integration and restructuring-related costs. The presentation of prior period amounts has been reclassified to be consistent with the current period presentation. Such reclassifications had no impact on total operating revenues, operating expenses, net income, total assets, total liabilities, or equity attributable to Invesco Ltd. |
| Acquisition Accounting | Acquisition Accounting In accordance with ASC Topic 805, “Business Combinations," any excess of the cost of the acquisition over the fair values of the identifiable net assets acquired attributable to the company is recognized as goodwill. With certain exceptions, 100% of the fair values of assets acquired, liabilities assumed, and noncontrolling interests is recognized in acquisitions of less than a 100% controlling interest when the acquisition constitutes a change in control of the acquired entity. Additionally, when partial ownership in an acquiree is obtained and it is determined that the company controls the acquiree, the assets acquired, liabilities assumed and any noncontrolling interests are recognized and consolidated at 100% of their fair values at that date, regardless of the percentage ownership in the acquiree. As goodwill is calculated as a residual, all goodwill of the acquired business, not just the company's share, is recognized under this “full-goodwill” approach. Noncontrolling interests are stated at the noncontrolling shareholder's proportion of the pre-acquisition carrying values of the acquired net assets. The results of entities acquired or sold during the year are included from or to the date control changes. Contingent consideration obligations that are elements of consideration transferred are recognized as of the acquisition date as part of the fair value transferred in exchange for the acquired business. Acquisition-related costs incurred in connection with a business combination are expensed as transaction, integration and restructuring costs. |
| Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents consist of cash held at banks and short-term investments with a maturity upon acquisition of three months or less. Cash and cash equivalents of CIP are not available for general use by the company. Cash balances may not be readily accessible to the Parent due to capital adequacy requirements of certain of our subsidiaries. These and other similar provisions of applicable laws and regulations may have the effect of limiting withdrawals of capital, repayment of intercompany loans and payment of dividends by such entities. All of our regulated EU subsidiaries are subject to consolidated capital requirements under EU Directives, including those arising from the EU's Capital Requirements Directive and the U.K.'s Internal Capital Adequacy Assessment Process (ICAAP), and capital is maintained within this sub-group to satisfy these regulations. We meet these requirements in part by holding cash and cash equivalents. This retained cash can be used for general business purposes in the European sub-group in the countries where it is located. Due to the capital restrictions, the ability to transfer cash between certain jurisdictions may be limited. In addition, transfers of cash between international jurisdictions may have adverse tax consequences. The company is in compliance with all regulatory minimum net capital requirements. |
| Unsettled Fund Receivables and Payables | Unsettled Fund Receivables and Payables The company records unsettled fund receivables from underlying fund investors in certain fund products outside the U.S. when these investors place unsettled investments into the funds. Additionally, the company records unsettled fund receivables from certain non-U.S. funds during the settlement period when underlying fund investors redeem their holdings. Settlement periods for both receivables from underlying investors and funds are generally less than four days. Additionally, in its capacity as sponsor of UITs, the company records receivables from brokers, dealers, and clearing organizations for unsettled sell trades of securities and UITs in addition to receivables from customers for unsettled sell trades of UITs. The company also records payables to brokers, dealers, and clearing organization for unsettled buy trades of securities and UITs in addition to payables to customers for unsettled buy trades of securities and UITs. The presentation of the unsettled fund receivables and substantially offsetting payables at trade date reflects the legal relationship between the underlying investor and the company. |
| Accounts Receivable and Payable | Accounts Receivable and Payable Accounts receivable and payable are recorded at their original invoice amounts. Accounts receivable are also recorded less any allowance for uncollectible amounts. |
| Investments | Investments The majority of the company’s investment balances relate to balances held in affiliated funds. In the normal course of business, the company invests in various types of affiliated investment products, either as “seed money” or as longer-term investments alongside third-party investors, typically referred to as “co-investments.” Seed money investments are investments held in Invesco managed funds with the purpose of providing capital to the funds during their development periods to allow the funds to achieve critical mass, establish their track records, and obtain third-party investments. Seed money may also be held for regulatory purposes in certain jurisdictions. Co-investments are often required of the investment manager by third-party investors in closed-ended funds to demonstrate an aligning of the investment manager’s interests with those of the third-party investors. The company also invests in affiliated funds in connection with its deferred compensation plans, whereby certain employees defer portions of their annual bonus into funds. Investments are categorized in this Report as equity investments, available-for-sale investments, equity method investments, foreign time deposits, and other investments. See Note 3 “Investments” for additional details. Equity investments include seed money, investments held to settle the company's deferred compensation plan liabilities, and other equity securities. Equity investments are securities bought and held principally for the purpose of selling them in the near term. Equity investments are measured at fair value. Gains or losses arising from changes in the fair value of equity investments are included in income. Available-for-sale investments include co-investments in affiliated CLOs and investments in other debt securities. Available-for-sale investments are measured at fair value. Gains or losses arising from changes in the fair value of available-for-sale investments are recognized in accumulated other comprehensive income, net of tax, until the investment is sold or otherwise disposed of, or if the investment is determined to be other-than-temporarily impaired, at which time the cumulative gain or loss previously reported in equity is included in income. The specific identification method is used to determine the realized gain or loss on securities sold or otherwise disposed. Equity method investments include investments over which the company is deemed to have significant influence, including corporate joint ventures and non-controlled entities in which the company's ownership is between 20 and 50 percent, and co-investments in certain managed funds generally structured as partnerships or similar vehicles. Investments in joint ventures are investments jointly controlled by the company and external parties. Co-investments in managed funds structured as partnerships or similar vehicles include private equity, real estate, and fund-of-funds. The equity method of accounting requires that the investment is initially recorded at cost, including any excess value paid over the book value of the investment acquired. The carrying amount of the investment is increased or decreased to recognize the company's share of the after-tax profit or loss of the investee after the date of acquisition and is decreased as dividends are received. Distributions received from equity method investees are classified in the Consolidated Statement of Cash Flows as either operating or investing activities based on the nature of the distribution. The proportionate share of income or loss is included in equity in earnings of unconsolidated affiliates in the Consolidated Statements of Income, and the proportionate share of other comprehensive income or loss is included in accumulated other comprehensive income in the Consolidated Balance Sheets. Seed money and co-investments in managed funds are required to be consolidated by the company if certain criteria are met. Upon consolidation of material balances, the company’s seed money or co-investment balance is eliminated, and the underlying investments of the managed fund are reflected on the company’s Consolidated Balance Sheets at fair value. These underlying investments are presented in the company's Consolidated Financial Statements as CIP investments. See “Basis of Accounting and Consolidation” for additional information regarding the consolidation criteria. If the company subsequently determines that it no longer controls the managed funds in which it has invested, the company will deconsolidate the funds. Any remaining holding in the managed funds is then accounted for on the basis described above. Fair value is determined using a valuation hierarchy (discussed in Note 2 , “Fair Value of Assets and Liabilities”), generally by reference to an active trading market, using quoted closing or bid prices as of each reporting period end. When a readily ascertainable market value does not exist for an investment, the fair value is calculated based on the expected cash flows of its underlying net asset base, taking into account applicable discount rates and other factors. Judgment is used to ascertain if a formerly active market has become inactive and in determining fair values when markets have become inactive. |
| Assets Held for Policyholders and Policyholder Payables | Assets Held for Policyholders and Policyholder Payables One of the company's subsidiaries, Invesco Perpetual Life Limited, is an insurance entity that was established to facilitate retirement savings plans in the U.K. The entity holds assets that are managed for its clients on its balance sheet with an equal and offsetting liability to the policyholders, which is linked to the value of the investments. The investments are legally segregated and are generally not subject to claims that arise from any of the company's other businesses. Investments and policyholder payables held by this business meet the definition of financial instruments and are carried in the Consolidated Balance Sheets as separate account assets and liabilities at fair value in accordance with ASC Topic 944, “Financial Services - Insurance.” Changes in fair value are recorded and offset to zero in the Consolidated Statements of Income in other operating revenues. Management fees earned from policyholder investments are accounted for as described in the company's revenue recognition accounting policy. |
| Deferred Sales Commissions | Deferred Sales Commissions Mutual fund shares sold without a sales commission at the time of purchase typically have an asset-based fee (12b-1 fee) that is charged to the fund over a period of years and a contingent deferred sales charge (CDSC). The CDSC is an asset-based fee that is charged to investors that redeem during a stated period. Commissions paid at the date of sale to brokers and dealers for sales of mutual funds that have a CDSC are capitalized and amortized over a period not to exceed the redemption period of the related fund (generally up to six years ). The deferred sales commission asset, which is included in prepaid assets in our Consolidated Balance Sheets, is reviewed periodically for impairment by reviewing the recoverability of the asset based on estimated future fees to be collected. |
| Property, Equipment, Software and Depreciation | Property, Equipment, Software and Depreciation Property, equipment and software includes owned property, leasehold improvements, computer hardware/software and other equipment and is stated at cost less accumulated depreciation or amortization and any previously recorded impairment in value. Expenditures for major additions and improvements are capitalized; minor replacements, maintenance and repairs are charged to expense as incurred. Amounts incurred are presented as work-in-progress until the construction or purchase of the property and equipment is substantially complete and ready for its intended use, which, at that point, will begin to be depreciated or amortized. Depreciation is provided on property and equipment at rates calculated to write off the cost, less estimated residual value, of each asset on a straight-line basis over its expected useful life: owned buildings over 50 years , leasehold improvements over the shorter of the lease term or useful life of the improvement; and computers and other various equipment between three and seven years. Purchased and internally developed software is capitalized where the related costs can be measured reliably, and it is probable that the asset will generate future economic benefits, and amortized into operating expenses on a straight-line basis over its useful life, generally over five to seven years. The company capitalizes qualified internal and external costs incurred during the application development stage for internally developed software in accordance with ASC Topic 350-40, “Intangibles - Goodwill and Other - Internal-Use Software.” The company reevaluates the useful life determination for property and equipment each reporting period to determine whether events and circumstances warrant a revision to the remaining useful life. On sale or retirement, the asset cost and related accumulated depreciation are removed from the Consolidated Financial Statements and any related gain or loss is reflected in income. The carrying amounts of property and equipment are reviewed for impairment when events or changes in circumstances indicate that the carrying values may not be recoverable. At each reporting date, an assessment is made for any indication of impairment. If an indication of impairment exists, recoverability is tested by comparing the carrying amount of the asset to the net undiscounted cash flows expected to be generated from the asset. If those net undiscounted cash flows do not exceed the carrying amount (i.e. the asset is not recoverable), the next step would be performed, which is to determine the fair value of the asset and record an impairment charge, if any. |
| Intangible Assets | Intangible Assets Intangible assets identified on the acquisition of a business are capitalized separately from goodwill if the fair value can be measured reliably on initial recognition (transaction date) and, if they are determined to be finite-lived, are amortized and recorded as transaction, integration and restructuring expenses on a straight-line basis over their useful lives, from two to twelve years, which reflects the pattern in which the economic benefits are realized. The company reevaluates the useful life determination for intangible assets each reporting period to determine whether events and circumstances warrant a revision to the remaining useful life or an indication of impairment. Intangible assets consist primarily of mutual fund and other client management contracts, customer relationships and distribution agreements. The company considers its own assumptions, which require management's judgment, about renewal or extension of the term of the arrangement, consistent with its expected use of the asset. A change in the useful life of an intangible asset could have a significant impact on the company's amortization expense. Where evidence exists that the underlying arrangements have a high likelihood of continued renewal at little or no cost to the company, the intangible asset is assigned an indefinite life and reviewed for impairment on an annual basis. Management contracts that are managed and operated on a single global platform are reviewed in aggregate as one unit of valuation and are considered interchangeable because investors may freely transfer between funds. Similarly, cash flows generated by new funds added to the global platform are included when determining the fair value of the intangible asset. Intangible assets not subject to amortization are tested for impairment annually as of October 1 or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of an intangible asset with its carrying amount. If the carrying amount of the intangible asset exceeds its fair value, an impairment loss is recognized into transaction, integration and restructuring expenses in an amount equal to that excess. Fair value is generally determined using an income approach where estimated future cash flows are discounted to arrive at a single present value amount. |
| Goodwill | Goodwill Goodwill represents the excess of cost over the identifiable net assets of businesses acquired and is recorded in the functional currency of the acquired entity. Goodwill is recognized as an asset and is reviewed for impairment annually as of October 1 and between annual tests when events and circumstances indicate that impairment may have occurred. The company has determined that it has one reporting unit for goodwill impairment testing purposes, the consolidated Invesco Ltd. single operating segment, which is consistent with internal management reporting and management's oversight of operations. The company evaluated the components of its business, which are business units one level below the operating segment level in making this determination. The company's operating segment represents one reporting unit because all of the components are similar due to the common nature of products and services offered, type of clients, methods of distribution, manner in which each component is operated, extent to which they share assets and resources, and the extent to which they support and benefit from common product development efforts. Traditional profit and loss measures are not produced and therefore not reviewed by component management for any of the components. Furthermore, the financial information that is available by component is not sufficient for purposes of performing a discounted cash flow analysis at the component level in order to test goodwill for impairment at that level. As none of the company's components are reporting units, the company has determined that its single operating segment, investment management, is also its single reporting unit. ASU 2011-08 allows the option to first qualitatively assess whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If not utilized, a quantitative impairment test is performed at the reporting unit level, which consists of a two-step approach. If the carrying amount of the reporting unit exceeds its fair value (the first step of the goodwill impairment test), then the second step is performed to determine if goodwill is impaired and to measure the amount of the impairment loss, if any. The second step of the goodwill impairment test compares the implied fair value of goodwill with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value of goodwill, an impairment loss is recognized in an amount equal to that excess. The principal method of determining fair value of the reporting unit is an income approach where estimated future cash flows are discounted to arrive at a single present value amount. The discount rate used is derived based on the time value of money and the risk profile of the stream of future cash flows. Recent results and projections based on expectations regarding revenue, expenses, capital expenditure and acquisition earn out payments produce a present value for the reporting unit. The present value produced for the reporting unit is the fair value of the reporting unit. This amount is reconciled to the company's market capitalization to determine an implied control premium, which is compared to an analysis of historical control premiums experienced by peer companies over a long period of time to assess the reasonableness of the fair value of the reporting unit. The company also utilizes a market approach to provide a secondary and corroborative fair value of the reporting unit by using comparable company and transaction multiples to estimate values for our single reporting unit. Discretion and judgment are required in determining whether the transaction data available represents information for companies of comparable nature, scope and size. The results of the secondary market approach to provide a fair value estimate are not combined or weighted with the results of the income approach described above but are used to provide an additional basis to determine the reasonableness of the income approach fair value estimate. |
| Debt and Financing Costs | Debt and Financing Costs Debt issuance costs related to the issuance of Senior Notes are presented as a deduction from the carrying amount of the related debt liability. Debt issuance costs related to the company's credit facility are presented as a deferred asset within Other Assets on the company's Consolidated Balance Sheets. After initial recognition, debt issuance costs are measured at amortized cost. Finance charges and debt issuance costs are amortized over the term of the debt using the effective interest method. Interest charges are recognized in the Consolidated Statement of Income in the period in which they are incurred. |
| Revenue Recognition | Revenue Recognition Revenue is measured and recognized based on the five step process outlined in ASC 606, Revenue from Contracts with Customers. Revenue is determined based on the transaction price negotiated with the customer, net of discounts, value added tax and other sales-related taxes. Investment management fees are derived from providing professional services to manage client accounts and sponsored investment vehicles. Investment management services are satisfied over time as the services are provided and are typically based upon a percentage of the value of the client’s assets under management. Investment management fees for certain arrangements include fees for distribution and administrative-related services. Any fees collected in advance are deferred and recognized as income over the period in which services are rendered. Service fees are earned for services rendered relating to fund accounting, transfer agent, administrative and/or other maintenance activities performed for sponsored investment vehicles. Service fees are generally based upon a percentage of the value of the assets under management. Service fees are also earned from the delivery of digital solutions to our customers. All of these services are transferred over time. The company provides distribution services to certain sponsored investment vehicles. Fees are generally earned based upon a percentage of the value of the assets under management, as the fee amounts do not crystallize completely upon the sale of a share or unit. Accordingly, the distribution fee revenues are recognized over time as the amount of the fees becomes known. For example, U.S. distribution fees can include 12b-1 fees earned from certain mutual funds to cover allowable sales and marketing expenses for those funds and also include asset-based sales charges paid by certain mutual funds for a period of time after the sale of those funds. Generally, retail products offered outside of the U.S. do not generate a separate distribution fee; the quoted management fee rate is inclusive of these services. The company also has certain arrangements whereby the distribution fees are paid upon the subscription or redemption of a share or unit. Performance fee revenues associated with retail funds will fluctuate from period to period and may not correlate with general market changes, since most of the fees are driven by relative performance to the respective benchmark rather than by absolute performance. Performance fee revenues, including carried interests and performance fees related to partnership investments and separate accounts, are generated on certain management contracts when performance hurdles are achieved. Such fee revenues are recorded in operating 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. Cash receipt of performance fees generally occurs after the performance fee revenue is earned; however, the company may receive, from time-to-time, cash distributions of carried interest before any revenue is earned. Such distributions are reflected as deferred carried interest liabilities within accounts payable and accrued expenses on the Condensed Consolidated Balance Sheets. Given the uniqueness of each fee arrangement, performance fee contracts are evaluated on an individual basis to determine the timing of revenue recognition. Performance fees typically arise from investment management activities that were initially undertaken in prior reporting periods. Other revenues include fees derived primarily from transaction commissions earned upon the sale of new investments into certain of our funds and fees earned upon the completion of transactions in our real estate and private equity asset groups. Real estate transaction fees are derived from commissions earned through the buying and selling of properties. Private equity transaction fees include commissions associated with the restructuring of, and fees from providing advice to, portfolio companies held by the funds. These transaction fees are recorded in the Condensed Consolidated Statements of Income on the date when Invesco’s services are complete which typically coincides with when the transactions are legally complete. Principal versus Agent The company utilizes third party service providers to fulfill certain performance obligations in its revenue agreements. Generally, the company is deemed to be the principal in these arrangements, because the company controls the investment management and other related services before they are transferred to customers. Such control is evidenced by the company’s primary responsibility to customers, the ability to negotiate the third party contract price and select and direct third party service providers, or a combination of these factors. Therefore, investment management and service and distribution fee revenues and the related third party distribution, service and advisory expenses are reported on a gross basis. Third-party distribution, service and advisory expenses include periodic “renewal” commissions paid to brokers and independent financial advisors for the continuing oversight of their clients' assets over the time they are invested and are payments for the servicing of client accounts. Renewal commissions are calculated based upon a percentage of the AUM value and apply to much of the company's non-U.S. retail operations. As discussed above, the revenues from the company’s U.S. retail operations include 12b-1 distribution fees, which are largely passed through to brokers who sell the funds as third-party distribution expenses along with additional marketing support distribution costs. Both the revenues and the costs are dependent on the underlying AUM of the brokers' clients. Third-party distribution expenses also include the amortization of upfront commissions paid to broker-dealers for sales of fund shares with a contingent deferred sales charge (a charge levied to the investor for client redemption of AUM within a certain contracted period of time). The upfront distribution commissions are amortized over the redemption period. Also included in third-party distribution, service and advisory expenses are sub-transfer agency fees that are paid to third parties for processing client share purchases and redemptions, call center support and client reporting. These costs are reimbursed by the related funds. |
| Share-Based Compensation | Share-Based Compensation The company issues equity-settled share-based awards to certain employees, which are measured at fair value at the date of grant. The fair value determined at the grant date is expensed, based on the company's estimate of shares that will eventually vest, on a straight-line or accelerated basis over the vesting period. The initial forfeiture rate applied to most grants is 3% per year, based upon the company's historical experience with respect to employee turnover. Fair value for the share awards representing equity interests identical to those associated with shares traded in the open market is determined using the market price at the date of grant. |
| Deferred Compensation | Deferred Compensation The company issues deferred cash awards to certain employees which are linked in value to investment products. The employees may earn a return linked to the appreciation or depreciation of specified investments, typically the funds they manage. The company currently hedges economically the exposure to market movements on certain of its deferred compensation plans by holding the investments on its balance sheet and through a total return swap financial instrument. The company recognizes as compensation expense the value of the liability to employees, including the appreciation or depreciation of the liability, over the award's vesting period in proportion to the vested amount of the award. The company immediately recognizes the full value of the related investment, and any subsequent appreciation or depreciation of the investment, in Other gains and losses, net. |
| Pensions | Pensions For defined contribution plans, contributions payable related to the accounting period are charged to the income statement. For defined benefit plans, the cost of providing benefits is separately determined for each plan using the projected unit credit method, based on actuarial valuations performed at each balance sheet date. The company's annual measurement date is December 31. A portion of actuarial gains and losses is recognized through the income statement if the net cumulative unrecognized actuarial gain or loss at the end of the prior period exceeds the greater of 10.0% of the present value of the defined benefit obligation (before deducting plan assets) at that date and 10.0% of the fair value of any plan assets. |
| Advertising Costs | Advertising Costs The company expenses the cost of all advertising and promotional activities as incurred. The company incurred advertising costs of $35.2 million for the year ended December 31, 2018 ( December 31, 2017 : $35.9 million ; December 31, 2016 : $32.7 million ). These amounts are included in marketing expenses in the Consolidated Statements of Income. |
| Leases | Leases The company complied with lease accounting guidance within ASC Topic 840, "Leases” for the financial periods presented in this Report. Under operating leases, where the lessor retains substantially all the risks and benefits of ownership of the asset, rental payments, as well as any step rent provisions specified in lease agreements, are aggregated and charged evenly to expense over the lease term beginning on the date of initial possession or the effective date of the lease agreement. Maintenance, utility, and tax costs included in lease agreements are expensed in the period incurred. Rental payments dependent upon an existing index or rate are included in the minimum lease payments based on the index or rate in effect at the inception of the lease and are recognized on a straight-line basis over the minimum lease term. Changes in rental payments that result from subsequent changes in the index or rate are expensed in the period incurred. Capital improvement funding and other lease concessions provided by the landlord are recorded as a deferred liability and are amortized evenly over the lease term as a reduction of rental expense. For the periods presented in this Report, the company accounted for lease termination costs in accordance with ASC Topic 420, “Exit or Disposal Cost Obligations,” which requires that (1) a liability for costs to terminate a contract before the end of its term shall be recognized at the time termination occurs and measured at fair value and (2) a liability for costs that will continue to be incurred under a contract for its remaining term without economic benefit to the company be recognized and measured at its fair value when the company ceases to use the right conveyed by the contract, net of estimated sublease rentals that could reasonably be obtained even if the company does not anticipate entering into any subleasing arrangements. |
| Taxation | Taxation Income taxes are provided for in accordance with ASC Topic 740, “Income Taxes” (ASC Topic 740). Deferred tax assets and liabilities are recorded for temporary differences between the tax basis of assets and liabilities and the reported amounts in the Consolidated Financial Statements, using the statutory tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets to the amount that is more likely than not to be realized. The company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense. |
| Earnings Per Share | Earnings Per Share Basic and diluted earnings per share are computed using the two-class method, which treats unvested restricted shares as if they were a separate class of shares. Under the two-class method, net income attributable to Invesco Ltd. is adjusted for the allocation of earnings to the unvested restricted shares. In addition, the weighted-average shares outstanding is adjusted for unvested restricted shares. There is no difference between the calculated earnings per share amounts attributable to Invesco Ltd. and the calculated earnings per share amounts under the two-class method. |
| Comprehensive Income | Comprehensive Income The company's other comprehensive income/(loss) consists of foreign currency translation adjustments, employee benefit plan liability adjustments, changes in unrealized gains and losses and reclassification adjustments for realized gains/(losses) on investment securities classified as available-for-sale, and the company's share of other comprehensive income of equity method investments. Such amounts are recorded net of applicable taxes. |
| Dividends to Shareholders | Dividends to Shareholders Dividends to shareholders are recognized on the declaration date. Dividends are declared and paid on a quarterly basis. |
| Translation of Foreign Currencies | Translation of Foreign Currencies Transactions in foreign currencies (currencies other than the functional currencies of the company's subsidiaries) are recorded at the rates of exchange prevailing on the dates of the transactions. At each balance sheet date, monetary assets and liabilities that are denominated in foreign currencies are remeasured into the functional currencies of the company's subsidiaries at the rates prevailing at the balance sheet date. Gains and losses arising on revaluation are included in the Consolidated Statements of Income. The company's reporting currency and the functional currency of the Parent is U.S. Dollars. On consolidation, the assets and liabilities of company subsidiary operations whose functional currencies are currencies other than the U.S. Dollar (“foreign” operations) are translated at the rates of exchange prevailing at the balance sheet date. Consolidated Statements of Income amounts are translated at the weighted average rates for the year, which approximate actual exchange rates. Exchange differences arising on the translation of the net assets of foreign operations are taken directly to accumulated other comprehensive income in equity until the disposal of the net investment, at which time they are recognized in the Consolidated Statements of Income. Goodwill and other fair value adjustments arising on acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and are translated at rates of exchange prevailing at the balance sheet date. The company has in the past purchased several put option contracts to hedge economically foreign currency risk on the translation of its Pound Sterling- and Euro-denominated earnings into U.S. Dollars. See Note 2 , "Fair Value of Assets and Liabilities," for additional information. Additionally, the company may, from time to time, designate certain intercompany debt as non-derivative net investment hedging instruments against foreign currency exposure related to its net investment in foreign operations. See Note 10 , "Other Comprehensive Income/(Loss)." In the management of its cross-border fund operations, foreign currency forward and swap contracts are purchased daily to hedge against foreign exchange rate movements during the four-day client money settlement period. Certain CIP may also utilize such instruments. |
