Accounting Policies [Abstract]
ACCOUNTING POLICIES	ACCOUNTING POLICIES Corporate Information Invesco Ltd. (Parent) and all of its consolidated entities (collectively, the company or Invesco) provide retail and institutional clients with an array of global investment management capabilities. The company operates globally and its sole business is investment management. Certain disclosures included in the company's annual report are not required to be included on an interim basis in the company's quarterly reports on Forms 10-Q. The company has condensed or omitted the disclosures. Therefore, this Form 10-Q (Report) should be read in conjunction with the company's annual report on Form 10-K for the year ended December 31, 2014 . Basis of Accounting and Consolidation The unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with rules and regulations of the Securities and Exchange Commission. In the opinion of management, the financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for the fair statement 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 Condensed Consolidated Financial Statements have been prepared in accordance with U.S. GAAP and consolidate the financial statements of the Parent and all of its controlled subsidiaries. Accounting Pronouncements Recently Adopted and Pending Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update 2014-09, "Revenue from Contracts with Customers" (ASU 2014-09), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 was originally effective for fiscal years and interim periods within those years beginning after December 15, 2016. In July 2015, the FASB voted to defer ASU 2014-09 by one year making it effective for fiscal years and interim periods within those years beginning after December 15, 2017. Early adoption is permitted as of the original effective date and requires either a retrospective or a modified retrospective approach to adoption. The company is currently evaluating the potential impact on its Consolidated Financial Statements, as well as the available transition methods. In August 2014, the FASB issued Accounting Standard Update 2014-13, "Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity" (ASU 2014-13). ASU 2014-13 provides a measurement alternative for an entity that consolidates a collateralized financing entity (CFE) and has elected the fair value option for the financial assets and financial liabilities of such CFE. The measurement alternative requires that the reporting entity measure both the financial assets and the financial liabilities of the CFE by using the more observable of the fair value of the financial assets and the fair value of the financial liabilities, removing any measurement difference previously recorded as net income (loss) attributable to noncontrolling interests in consolidated entities and as an adjustment to retained earnings appropriated for investors in CIP. On January 1, 2015 the company adopted ASU 2014-13 on a modified retrospective basis and has elected the measurement alternative for the consolidated CLOs. The adoption resulted in a $17.6 million reduction in retained earnings appropriated for investors in CIP, with a corresponding increase in debt of CIP. The company’s subsequent 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 will no longer be attributed to noncontrolling interests but will offset in other gains/(losses) of CIP. In February 2015, the FASB issued Accounting Standard Update 2015-02, “ Amendments to the Consolidation Analysis” (ASU 2015-02). This standard modifies existing consolidation guidance for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 is effective for fiscal years and interim periods within those years beginning after December 15, 2015, and requires either a retrospective or a modified retrospective approach to adoption. Early adoption is permitted. The company is currently evaluating the potential impact of this standard on its Consolidated Financial Statements, as well as the available transition methods. In April 2015, the FASB issued Accounting Standards Update 2015-03, "Simplifying the Presentation of Debt Issuance Costs" (ASU 2015-03), which changes the presentation of debt issuance costs in the balance sheet. ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability rather than being presented as an asset. Amortization of debt issuance costs will continue to be reported as interest expense. ASU 2015-03 is effective for fiscal years and interim periods within those years beginning after December 15, 2015, and requires retrospective application for each prior period presented. Early adoption is permitted. The company is currently evaluating the potential impact of this standard on its Consolidated Financial Statements. In May 2015, the FASB issued Accounting Standards Update 2015-07, "Fair Value Measurement - Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)" (ASU 2015-07). ASU 2015-07 removes the requirement to categorize investments within the fair value hierarchy for which fair value is measured using the net asset value practical expedient. ASU 2015-07 is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2015, and requires retrospective application for each prior period presented. Early adoption is permitted. While the company is still evaluating the impact of ASU 2015-07, adoption will not impact the company's financial condition, results of operations or cash flows, as the update relates to financial statement disclosures.

See the indicated footnotes or most recently filed Form 10-K for additional information about the carrying and fair values of these financial instruments. Foreign time deposits are measured at cost plus accrued interest, which approximates fair value, and are accordingly classified as Level 2 securities. A three-level valuation hierarchy exists for disclosure of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows: • Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 - inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 - inputs to the valuation methodology are unobservable and significant to the fair value measurement. An asset or liability's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. There are three types of valuation approaches: a market approach, which uses observable prices and other relevant information that is generated by market transactions involving identical or comparable assets or liabilities; an income approach, which uses valuation techniques to convert future amounts to a single, discounted present value amount; and a cost approach, which is based on the amount that currently would be required to replace the service capacity of an asset. The following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy. Cash equivalents Cash investments in money market funds are valued under the market approach through the use of quoted market prices in an active market, which is the net asset value of the underlying funds, and are classified within level 1 of the valuation hierarchy. Available-for-sale investments Seed money is valued under the market approach through the use of quoted market prices available in an active market and is classified within level 1 of the valuation hierarchy; there is no modeling or additional information needed to arrive at the fair values of these investments. CLO assets are valued based on price quotations provided by an independent third-party pricing source or using an income approach through the use of certain observable and unobservable inputs. At June 30, 2015 and December 31, 2014 , investments in CLOs were valued using third-party pricing information. Due to liquidity constraints within the market for CLO products that require the use of unobservable inputs, these investments are classified within level 3 of the valuation hierarchy. Other debt securities are valued using a cost valuation technique due to the lack of available cash flow and market data and are accordingly also classified within level 3 of the valuation hierarchy. Trading investments • Investments related to deferred compensation plans Investments related to deferred compensation plans are valued under the market approach through the use of quoted prices in an active market and are classified within level 1 of the valuation hierarchy. • Seed money Seed money is valued under the market approach through the use of quoted market prices available in an active market and is classified within level 1 of the valuation hierarchy; there is no modeling or additional information needed to arrive at the fair values of these investments. • Other equity securities These securities are valued under the market approach through the use of quoted prices in an active market. To the extent these securities are actively traded, valuation adjustments are not applied and they are categorized within level 1 of the valuation hierarchy; otherwise, they are categorized in level 2. • UIT-related equity and debt securities The company invests in UIT-related equity and debt securities consisting of investments in corporate equities, UITs, and municipal securities. Each is discussed more fully below. Corporate equities The company temporarily holds investments in corporate equities for purposes of creating a UIT. Corporate equities are valued under the market approach through use of quoted prices on an exchange. To the extent these securities are actively traded, valuation adjustments are not applied and they are categorized within level 1 of the valuation hierarchy; otherwise, they are categorized in level 2. UITs The company may hold units of its sponsored UITs at period-end for sale in the primary market or secondary market. Equity UITs are valued under the market approach through use of quoted prices on an exchange. Fixed income UITs are valued using recently executed transaction prices, market price quotations (where observable), bond spreads, or credit default swap spreads. The spread data used is for the same maturities as the underlying bonds. If the spread data does not reference the issuers, then data that references comparable issuers is used. When observable price quotations are not available, fair value is determined based on cash flow models with yield curves, bond or single name credit default spreads, and recovery rates based on collateral value as key inputs. Depending on the nature of the inputs, these investments are categorized as level 1, 2, or 3. Municipal securities Municipal securities are valued using recently executed transaction prices, market price quotations (where observable), bond spreads, or credit default swap spreads. The spread data used is for the same maturities as the underlying bonds. If the spread data does not reference the issuers, then data that references comparable issuers is used. When observable price quotations are not available, fair value is determined based on cash flow models with yield curves, bond or single name credit default spreads, and recovery rates based on collateral value as key inputs. Depending on the nature of the inputs, these investments are categorized as level 1, 2, or 3. Put option contracts The company has purchased several put option contracts to hedge economically foreign currency risk on the translation of a portion of its pound sterling-denominated earnings into U.S. dollars (purchases of $2.4 million and $9.2 million in the three and six months ended June 30, 2015 , respectively). These were the only contracts entered into during the period to hedge economically foreign currency risk and provide coverage through March 31, 2016 . The economic hedge is predominantly triggered upon the impact of a significant decline in the pound sterling/U.S. dollar foreign exchange rate, which could arise as a result of European economic uncertainty. Open put option contracts are marked-to-market through earnings, which are recorded in the company's Condensed Consolidated Statements of Income in other gains and losses. These derivative contracts are valued using option valuation models and are included in other assets in the company's Condensed Consolidated Balance Sheets. The significant inputs in these models (volatility, forward points and swap curves) are readily available in public markets or can be derived from observable market transactions for substantially the full terms of the contracts and are classified within level 2 of the valuation hierarchy. The company recognized losses of $8.4 million and $7.8 million in the three and six months ended June 30, 2015 , respectively (three and six months ended June 30, 2014 : none ) related to the change in market value of these put option contracts. Assets held for policyholders Assets held for policyholders are measured at fair value under the market approach based on the quoted prices of the underlying funds in an active market and are classified within level 1 of the valuation hierarchy. The policyholder payables are indexed to the value of the assets held for policyholders and are therefore not included in the tables below. UIT-related financial instruments sold, not yet purchased, and derivative instruments The company uses U.S. Treasury futures, which are types of derivative financial instruments, to hedge economically fixed income UIT inventory and securities in order to mitigate market risk. Open futures contracts are marked-to-market daily through earnings, which are recorded in the company’s Condensed Consolidated Statements of Income in other revenue, along with the mark-to-market on the underlying trading securities held. Fair values of derivative contracts in an asset position are included in other assets in the company’s Condensed Consolidated Balance Sheets. Fair values of derivative contracts in a liability position are included in other liabilities in the company’s Condensed Consolidated Balance Sheets. These derivative contracts are valued under the market approach through use of quoted prices in an active market and are classified within level 1 of the valuation hierarchy. At June 30, 2015 there were 23 futures contracts with a notional value of $3.2 million ( December 31, 2014 : 6 open futures contracts with a notional value of $0.8 million ). Additionally, to hedge economically the market risk associated with equity and debt securities and UITs temporarily held as trading investments, the company will hold short corporate equities, exchange-traded funds, or U.S. treasury security positions. These transactions are recorded as financial instruments sold, not yet purchased and are included in accounts payable and accrued expenses in the company’s Condensed Consolidated Balance Sheets. To the extent these securities are actively traded, valuation adjustments are not applied and they are categorized within level 1 of the valuation hierarchy; otherwise, they are categorized in level 2. Contingent Consideration Liability During the six months ended June 30, 2015 , the company acquired certain investment management contracts from a third party. Indefinite-lived intangible assets were valued at $119.3 million . This transaction was a non-cash investing activity during the period. The purchase price was comprised solely of contingent consideration payable in future periods, and is linked to future revenues generated from the contracts. The contingent consideration liability was recorded at fair value as of the date of acquisition using a discounted cash flow model, and is categorized within level 3 of the valuation hierarchy. Anticipated future cash flows were determined using forecast AUM levels and discounted back to the valuation date using a discount rate of 3.4% . Assumed growth rates in AUM ranged from 0% to 5% (weighted average growth rate of 2.89% ). The company reassesses significant unobservable inputs during each reporting period. Changes in fair value are recorded in Other gains and losses, net in the Condensed Consolidated Statements of Income in the period incurred. An increase in AUM levels and a decrease in the discount rate would increase the fair value of the contingent consideration liability while a decrease in forecasted AUM and an increase in the discount rate would decrease the liability.

Beyond these items, there are no other restrictive covenants in the indentures. The issuer of the senior notes is an indirect 100% owned finance subsidiary of Invesco Ltd. (the Parent), and the Parent fully and unconditionally guaranteed the securities. The requirement of certain subsidiaries of the Parent to maintain minimum levels of capital and other similar provisions of applicable law may have the effect of limiting withdrawals of capital, repayment of intercompany loans and payment of dividends by such entities. The fair market value of the company's senior notes was determined by market quotes provided by Bloomberg, which is considered a Level 2 valuation input. In the absence of an active market, the company relies upon the average price quoted by brokers for determining the fair market value of the debt. At June 30, 2015 , the company's outstanding senior notes of $1,589.6 million mature in periods greater than five years from the balance sheet date. The floating rate credit facility will expire in less than five years. At June 30, 2015 , the outstanding balance on the $1.25 billion credit facility was $7.9 million ( December 31, 2014 : zero ). The credit facility has a maturity of December 17, 2018. Borrowings under the credit facility will bear interest at (i) LIBOR for specified interest periods or (ii) a floating base rate (based upon the highest of (a) the Bank of America prime rate, (b) the Federal Funds rate plus 0.50% and (c) LIBOR for an interest period of one month plus 1.00% ), plus, in either case, an applicable margin determined with reference to the higher of the available credit ratings of the company or its indirect subsidiary Invesco Finance PLC. Based on credit ratings as of June 30, 2015 of the company, the applicable margin for LIBOR-based loans was 1.00% and for base rate loans was 0.00% . In addition, the company is required to pay the lenders a facility fee on the aggregate commitments of the lenders (whether or not used) at a rate per annum which is based on the higher of the available credit ratings of the company or its indirect subsidiary Invesco Finance PLC. Based on credit ratings as of June 30, 2015 , the annual facility fee was equal to 0.125% . The credit agreement governing the credit facility contains customary restrictive covenants on the company and its subsidiaries. Restrictive covenants in the credit agreement include, but are not limited to: prohibitions on creating, incurring or assuming any liens; entering into merger arrangements; selling, leasing, transferring or otherwise disposing of assets; making a material change in the nature of the business; making a significant accounting policy change in certain situations; entering into transactions with affiliates; and incurring indebtedness through the subsidiaries. Many of these restrictions are subject to certain minimum thresholds and exceptions. Financial covenants under the credit agreement include: (i) the quarterly maintenance of a debt/EBITDA leverage ratio, as defined in the credit agreement, of not greater than 3.25 :1.00, (ii) a coverage ratio (EBITDA, as defined in the credit agreement/interest payable for the four consecutive fiscal quarters ended before the date of determination) of not less than 4.00 :1.00. The credit agreement governing the credit facility also contains customary provisions regarding events of default which could result in an acceleration or increase in amounts due, including (subject to certain materiality thresholds and grace periods) payment default, failure to comply with covenants, material inaccuracy of representation or warranty, bankruptcy or insolvency proceedings, change of control, certain judgments, ERISA matters, cross-default to other debt agreements, governmental action prohibiting or restricting the company or its subsidiaries in a manner that has a material adverse effect and failure of certain guaranty obligations. The company is in compliance with all regulatory minimum net capital requirements. The lenders (and their respective affiliates) may have provided, and may in the future provide, investment banking, cash management, underwriting, lending, commercial banking, leasing, foreign exchange, trust or other advisory services to the company and its subsidiaries and affiliates. These parties may have received, and may in the future receive, customary compensation for these services. The company maintains approximately $33.4 million in letters of credit from a variety of banks. The letters of credit are generally one -year automatically-renewable facilities and are maintained for various commercial reasons.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION The company recognized total expenses of $76.7 million and $70.0 million related to equity-settled share-based payment transactions in the six months ended June 30, 2015 and June 30, 2014 , respectively. Cash received from exercise of share options granted under share-based compensation arrangements was $1.2 million in the six months ended June 30, 2015 ( six months ended June 30, 2014 : $5.2 million ). Share Awards Share awards are broadly classified into two categories: time-vested and performance-vested. Share awards are measured at fair value at the date of grant and are expensed, based on the company's estimate of shares that will eventually vest, on a straight-line or accelerated basis over the vesting period. Time-vested awards vest ratably over or cliff-vest at the end of a period of continued employee service. Performance-vested awards cliff-vest at the end of or vest ratably over a defined vesting period of continued employee service upon the company's attainment of certain performance criteria. Time-vested and performance-vested share awards are granted in the form of restricted share awards (RSAs) or restricted share units (RSUs). Performance-vested awards are tied to the achievement of specified levels of adjusted diluted earnings per share and adjusted operating margin. In the event that either targeted financial measure is achieved at or above a vesting threshold for a particular performance measurement period, the portion of the performance-vested award subject to targeted financial measures will vest proportionately between 0% and 100% based upon the higher achieved level for that year. With respect to time-vested awards, dividends accrue directly to the employee holder of RSAs, and cash payments in lieu of dividends are made to employee holders of certain RSUs. With respect to performance-vested awards, dividends and cash payments in lieu of dividends are deferred and are paid at the same rate as on our shares if and to the extent the award vests. In May 2011, the company's shareholders approved the 2011 Global Equity Incentive Plan, which authorized the issuance of up to 28 million shares under this plan. In May 2010, the board approved the 2010 Global Equity Incentive Plan (ST), which authorized the issuance of up to 3 million shares under this plan. Under the terms of the plan, shares are issued only as employment inducement awards in connection with a strategic transaction and, as a result, do not require shareholder approval under the rules of the New York Stock Exchange or otherwise.

General Discussion of Pension and Other Postretirement Benefits [Abstract]
RETIREMENT BENEFIT PLANS	RETIREMENT BENEFIT PLANS Defined Contribution Plans The company operates defined contribution retirement benefit plans for all qualifying employees. The assets of the plans are held separately from those of the company in funds under the control of trustees. When employees leave the plans prior to vesting fully in the contributions, the contributions payable by the company are reduced by the amount of forfeited contributions. The total amounts charged to the Condensed Consolidated Statements of Income for the three and six months ended June 30, 2015 of $15.3 million and $30.7 million , respectively ( three and six months ended June 30, 2014 : $14.3 million and $29.7 million , respectively) represent contributions paid or payable to these plans by the company at rates specified in the rules of the plans. As of June 30, 2015 , accrued contributions of $16.1 million ( December 31, 2014 : $25.4 million ) for the current year will be paid to the plans. Defined Benefit Plans The company maintains legacy defined benefit pension plans for qualifying employees of its subsidiaries in the U.K., Ireland, Germany and Taiwan. All defined benefit plans are closed to new participants. The company also maintains a postretirement medical plan in the U.S., which was closed to new participants in 2005. In 2006, the plan was amended to eliminate benefits for all participants who did not meet retirement eligibility by 2008. In November 2014, Invesco further amended the plan, which will result in its termination effective December 31, 2016. The assets of all defined benefit schemes are held in separate trustee-administered funds. Under the plans, the employees are generally entitled to retirement benefits based on final salary at retirement. The components of net periodic benefit cost in respect of these defined benefit plans are as follows: Retirement Plans Medical Plan For the three months ended June 30, For the six months ended June 30, For the three months ended June 30, For the six months ended June 30, $ in millions 2015 2014 2015 2014 2015 2014 2015 2014 Service cost 1.3 1.1 2.5 2.2 — — — 0.1 Interest cost 5.2 4.7 10.5 9.5 — 0.5 — 1.0 Expected return on plan assets (6.1 ) (4.7 ) (12.3 ) (9.3 ) (0.1 ) (0.1 ) (0.2 ) (0.3 ) Amortization of prior service cost/(credit) 0.1 0.1 0.1 0.1 (2.5 ) (0.5 ) (4.7 ) (1.0 ) Amortization of net actuarial (gain)/loss 0.7 0.5 1.3 1.0 — 0.1 — 0.2 Net periodic benefit cost/(benefit) 1.2 1.7 2.1 3.5 (2.6 ) — (4.9 ) — The estimated amounts of contributions expected to be paid to the plans during 2015 are $15.2 million for retirement plans and none for the medical plan. Payments made to the plans during the six months ended June 30, 2015 were $3.8 million to the retirement plan and zero to the medical plan.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE Basic and diluted earnings per share are computed using the two-class method. 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. The calculation of earnings per share is as follows: For the three months ended June 30, For the six months ended June 30, In millions, except per share data 2015 2014 2015 2014 Income from continuing operations, net of taxes $244.0 $316.6 $528.0 $525.4 Net (income)/loss attributable to noncontrolling interests in consolidated entities 13.3 (42.3 ) (11.1 ) (61.3 ) Income from continuing operations attributable to Invesco Ltd. for basic and diluted EPS calculations 257.3 274.3 516.9 464.1 Income/(loss) from discontinued operations, net of taxes — 0.2 — (1.8 ) Net income attributable to Invesco Ltd. 257.3 274.5 516.9 462.3 Less: Allocation of earnings to restricted shares (6.6 ) (7.6 ) (13.3 ) (13.3 ) Net income attributable to common shareholders $250.7 $266.9 $503.6 $449.0 Invesco Ltd: Weighted average shares outstanding - basic 431.9 435.7 432.0 436.2 Dilutive effect of non-participating share-based awards 0.3 0.7 0.3 0.7 Weighted average shares outstanding - diluted 432.2 436.4 432.3 436.9 Common shareholders: Weighted average shares outstanding - basic 431.9 435.7 432.0 436.2 Less: Weighted average restricted shares (11.0 ) (12.0 ) (11.1 ) (12.5 ) Weighted average common shares outstanding - basic 420.9 423.7 420.9 423.7 Dilutive effect of non-participating share-based awards 0.3 0.7 0.3 0.7 Weighted average common shares outstanding - diluted 421.2 424.4 421.2 424.4 Basic earnings per share: Earnings per share from continuing operations $0.60 $0.63 $1.20 $1.06 Earnings per share from discontinued operations $— $— $— $— Basic earnings per share $0.60 $0.63 $1.20 $1.06 Diluted earnings per share: Earnings per share from continuing operations $0.60 $0.63 $1.20 $1.06 Earnings per share from discontinued operations $— $— $— $— Diluted earnings per share $0.60 $0.63 $1.20 $1.06 See Note 7 , “Share-Based Compensation,” for a summary of share awards outstanding under the company's share-based compensation programs. These programs could result in the issuance of common shares from time-to-time that would affect the measurement of basic and diluted earnings per share. There were no antidilutive options excluded from the computation of diluted earnings per share in the six months ended June 30, 2015 ( six months ended June 30, 2014 : none ). Antidilutive options are those where the options' exercise prices are greater than the average market price of the shares. There were no time-vested based awards that were excluded from the computation of diluted earnings per share during the six months ended June 30 , 2015 and 2014 , due to their inclusion being anti-dilutive. There were 0.4 million contingently issuable shares excluded from the diluted earnings per share computation during the six months ended June 30, 2015 ( six months ended June 30, 2014 : 0.3 million ), because the necessary performance conditions for the shares to be issuable had not yet been satisfied at the end of the respective period.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments and contingencies may arise in the ordinary course of business. Off Balance Sheet Commitments The company has transactions with various private equity, real estate and other investment entities sponsored by the company for the investment of client assets in the normal course of business. Many of the company's investment products are structured as limited partnerships. The company's investment may take the form of the general partner or a limited partner. The entities are structured such that each partner makes capital commitments that are to be drawn down over the life of the partnership as investment opportunities are identified. At June 30, 2015 , the company's undrawn capital commitments were $139.5 million ( December 31, 2014 : $158.8 million ). The Parent and various company subsidiaries have entered into agreements with financial institutions to guarantee certain obligations of other company subsidiaries. The company would be required to perform under these guarantees in the event of certain defaults. The company has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. Legal Contingencies The company is from time to time involved in litigation relating to claims arising in the ordinary course of its business. The nature and progression of litigation can make it difficult to predict the impact a particular lawsuit will have on the company. There are many reasons that the company cannot make these assessments, including, among others, one or more of the following: the proceeding is in its early stages; the damages sought are unspecified, unsupportable, unexplained or uncertain; the claimant is seeking relief other than compensatory damages; the matter presents novel legal claims or other meaningful legal uncertainties; discovery has not started or is not complete; there are significant facts in dispute; and there are other parties who may share in any ultimate liability. In management’s opinion, adequate accrual has been made as of June 30, 2015 to provide for any such losses that may arise from matters for which the company could reasonably estimate an amount. Management is of the opinion that the ultimate resolution of such claims will not materially affect the company’s business, financial position, results of operation or liquidity. Furthermore, in management’s opinion, it is not possible to estimate a range of reasonably possible losses with respect to other litigation contingencies. The investment management industry also is subject to extensive levels of ongoing regulatory oversight and examination. In the United States, United Kingdom, and other jurisdictions in which the company operates, governmental authorities regularly make inquiries, hold investigations and administer market conduct examinations with respect to the company's compliance with applicable laws and regulations. Additional lawsuits or regulatory enforcement actions arising out of these inquiries may in the future be filed against the company and related entities and individuals in the United States, United Kingdom, and other jurisdictions in which the company and its affiliates operate. Any material loss of investor and/or client confidence as a result of such inquiries and/or litigation could result in a significant decline in assets under management, which would have an adverse effect on the company’s future financial results and its ability to grow its business.

Equity securities are valued under the market approach through use of quoted prices on an exchange. To the extent these securities are actively traded, valuation adjustments are not applied and they are categorized within level 1 of the valuation hierarchy; otherwise, they are categorized in level 2. Fixed income securities are fair valued using an evaluated quote provided by an independent pricing service. Evaluated quotes provided by the pricing service may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to specific securities, yield, quality, type of issue, coupon rate, maturity, individual trading characteristics and other market data. Depending on the nature of the inputs, these investments are categorized as level 1, 2, or 3.

At December 31, 2014 , certain tranches of the consolidated CLOs are valued using third party pricing information. Quantitative unobservable inputs for such valuations were not developed or adjusted by the company. Investments in other private equity funds as of June 30, 2015 of $403.6 million (as of December 31, 2014 : $410.0 million ) are also excluded from the table above as they are valued using the NAV practical expedient. The NAVs that have been provided are derived from the fair values of the underlying investments as of the consolidation date. ** Lower spreads relate to the more senior tranches in the CLO note structure; higher spreads relate to the less senior tranches. *** Assumed default rates listed in the table above apply to CLOs established prior to 2012. A default rate of 2.0% was assumed for CLOs established after January 1, 2012.

The following narrative will indicate the sensitivity of inputs illustrating the impact of significant increases to the inputs. An opposite impact would result for significant decreases in these inputs: • For investments held by consolidated private equity funds, significant increases in discounts in isolation would result in significantly lower fair value measurements, while significant increases in revenue multiple assumptions in isolation would result in significantly higher fair value measurements. An increase in discount assumptions would result in a directionally opposite change in the assumptions for revenue multiple resulting in lower fair value measurements." id="sjs-B4">CONSOLIDATED INVESTMENT PRODUCTS The following table presents the balances related to CIP that are included on the Condensed Consolidated Balance Sheets as well as Invesco's net interest in the CIP for each period presented. As of $ in millions June 30, 2015 December 31, 2014 Cash and cash equivalents of CIP 314.8 404.0 Accounts receivable and other assets of CIP 109.5 161.3 Investments of CIP 6,185.1 5,762.8 Less: Debt of CIP (5,432.1 ) (5,149.6 ) Less: Other liabilities of CIP (326.8 ) (280.9 ) Less: Retained earnings (12.5 ) (20.3 ) Less: Retained earnings appropriated for investors in CIP — (17.6 ) Less: Accumulated other comprehensive income, net of tax 12.5 20.2 Less: Equity attributable to nonredeemable noncontrolling interests (739.9 ) (781.2 ) Invesco's net interests in CIP 110.6 98.7 Invesco's net economic interests as a percentage of investments of CIP 1.8 % 1.7 % The company's risk with respect to each investment in CIP is limited to its equity ownership and any uncollected management and performance fees. Therefore, the gains or losses of CIP have not had a significant impact on the company's net income attributable to Invesco Ltd., liquidity or capital resources. The company has no right to the benefits from, nor does it bear the risks associated with, these investments, beyond the company's minimal direct investments in, and management and performance fees generated from, the investment products. If the company were to liquidate, these investments would not be available to the general creditors of the company, and as a result, the company does not consider investments held by CIP to be company assets. Additionally, the collateral assets of consolidated collateralized loan obligations (CLOs) are held solely to satisfy the obligations of the CLOs, and the investors in the consolidated CLOs have no recourse to the general credit of the company for the notes issued by the CLOs.

The carrying values of investments held at June 30, 2015 and December 31, 2014 , and notes issued as of December 31, 2014 , are also their fair values. The company adopted ASU 2014-13 on January 1, 2015, and accordingly the notes issued by consolidated CLOs are no longer carried at fair value but are now measured under the measurement alternative discussed in Note 1 , "Accounting Policies - Accounting Pronouncements Recently Adopted and Pending Accounting Pronouncements."

During the six months ended June 30, 2015 , $0.6 million ( six months ended June 30, 2014 : zero ) of equity securities held by consolidated private equity funds were transferred from Level 3 to Level 1 following the public offering of the underlying companies. For transfers due to public offerings, the company's policy is to use the fair value of the transferred security at the end of the period. Unforeseen events might occur that would subsequently change the fair values of the investments (and therefore the debt of CLOs, since it is measured as a calculated value based upon the fair value of the assets of CLOs with effect from January 1, 2015), but the impact of such changes would be limited to the change in the fair values of the company's minimal investments in these products. The impact of any gains or losses resulting from valuation changes in the investments of non-CLO CIP attributable to the interests of third parties are offset by resulting changes in gains and losses attributable to noncontrolling interests in consolidated entities and therefore do not have a material effect on the financial condition, operating results (including earnings per share), liquidity or capital resources of the company's common shareholders. Similarly, any gains or losses resulting from valuation changes in the investments of CLOs attributable to the interests of third parties are offset by the calculated value of the notes issued by the CLOs (offsetting in other gains/(losses) of CIP) and therefore also do not have a material effect on the financial condition, operating results (including earnings per share), liquidity or capital resources of the company's common shareholders. Value of consolidated CLOs The company elected the fair value option for collateral assets held and notes issued by its consolidated CLOs to eliminate the measurement and recognition inconsistency that would otherwise arise from measuring assets and liabilities and recognizing the related gains and losses on different accounting bases. On January 1, 2015 the company adopted ASU 2014-13 and has elected the measurement alternative for the consolidated CLOs under which the notes issued by the CLOs are measured based on the fair value of the assets of the CLOs. Accordingly, the discussion below related to the fair value of notes issued by consolidated CLOs is applicable for the prior comparative period only. The collateral assets held by consolidated CLOs are primarily invested in senior secured bank loans, bonds, and equity securities. Bank loan investments, which comprise the majority of consolidated CLO portfolio collateral, are senior secured corporate loans from a variety of industries, including but not limited to the aerospace and defense, broadcasting, technology, utilities, household products, healthcare, oil and gas, and finance industries. Bank loan investments mature at various dates between 2015 and 2023 , pay interest at Libor plus a spread of up to 10.0% , and typically range in S&P credit rating categories from BBB down to unrated. Interest income on bank loans and bonds is recognized based on the unpaid principal balance and stated interest rate of these investments on an accrual basis. At June 30, 2015 , the unpaid principal balance exceeds the fair value of the senior secured bank loans and bonds by approximately $40.5 million ( December 31, 2014 : the unpaid principal balance exceeded the fair value of the senior secured bank loans and bonds by approximately $56.2 million ). Less than 0.1% of the collateral assets are in default as of June 30, 2015 ( December 31, 2014 : less than 0.1% of the collateral assets were in default). CLO investments are valued based on price quotations provided by third party pricing sources. These third party sources aggregate indicative price quotations daily to provide the company with a price for the CLO investments. The company has developed internal controls to review the reasonableness and completeness of these price quotations on a daily basis. If necessary, price quotations are challenged through the third-party pricing source price challenge process. For the six months ended June 30, 2015 and the year ended December 31, 2014 , there were no price quotation challenges by the company. In addition, the company's internal valuation committee conducts an annual due diligence review of all independent third-party pricing sources to review the provider's valuation methodology as well as ensure internal controls exist over the valuation of the CLO investments. In the event that the third-party pricing source is unable to price an investment, other relevant factors, data and information are considered, including: i) information relating to the market for the investment, including price quotations for and trading in the investment and interests in similar investments, the market environment, and investor attitudes towards the investment and interests in similar investments; ii) the characteristics of and fundamental analytical data relating to the investment, including, for senior secured corporate loans, the cost, size, current interest rate, period until next interest rate reset, maturity and base lending rate, the terms and conditions of the senior secured corporate loan and any related agreements, and the position of the senior secured corporate loan in the borrower's debt structure; iii) the nature, adequacy and value of the senior secured corporate loan's collateral, including the CLO's rights, remedies and interests with respect to the collateral; iv) for senior secured corporate loans, the creditworthiness of the borrower, based on an evaluation of its financial condition, financial statements and information about the business, cash flows, capital structure and future prospects; v) the reputation and financial condition of the agent and any intermediate participants in the senior secured corporate loan; and vi) general economic and market conditions affecting the fair value of the senior secured corporate loan. Notes issued by consolidated CLOs mature at various dates between 2020 and 2027 and have a weighted average maturity of 9.6 years. The notes are issued in various tranches with different risk profiles. The interest rates are generally variable rates based on Libor plus a pre-defined spread, which varies from 0.21% for the more senior tranches to 6.70% for the more subordinated tranches. The investors in this debt are not affiliated with the company and have no recourse to the general credit of the company for this debt . Notes issued by CLOs are recorded at fair value at December 31, 2014 using an income approach, driven by cash flows expected to be received from the portfolio collateral assets. Fair value is determined using current information, notably market yields and projected cash flows of collateral assets based on forecasted default and recovery rates that a market participant would use in determining the current fair value of the notes, taking into account the overall credit quality of the issuers and the company's past experience in managing similar securities. Market yields, default rates and recovery rates used in the company's estimate of fair value vary based on the nature of the investments in the underlying collateral pools. In periods of rising market yields, default rates and lower debt recovery rates, the fair value, and therefore the carrying value, of the notes may be adversely affected. The current liquidity constraints within the market for CLO products require the use of certain unobservable inputs for CLO valuation. Once the undiscounted cash flows of the collateral assets have been determined, the company applies appropriate discount rates that a market participant would use to determine the discounted cash flow valuation of the notes. Fair value of consolidated private equity funds Consolidated private equity funds are generally structured as partnerships. Generally, the investment strategy of underlying holdings in these partnerships is to seek capital appreciation through direct investments in public or private companies with compelling business models or ideas or through investments in partnership investments that also invest in similar private or public companies. Various strategies may be used. Companies targeted could be distressed organizations, targets of leveraged buyouts or fledgling companies in need of venture capital. Investors generally may not redeem their investment until the partnership liquidates. Generally, the partnerships have a life that ranges from seven to twelve years unless dissolved earlier. The general partner may extend the partnership term up to a specified period of time as stated in the Partnership Agreement. Some partnerships allow the limited partners to cause an earlier termination upon the occurrence of certain events as specified in the Partnership Agreement. For private equity partnerships, fair value is determined by reviewing each investment for the sale of additional securities of an issuer to sophisticated investors or for investee financial conditions and fundamentals. Publicly traded portfolio investments are carried at market value as determined by their most recent quoted sale, or if there is no recent sale, at their most recent bid price. For these investments held by CIP, level 1 classification indicates that fair values have been determined using unadjusted quoted prices in active markets for identical assets that the partnership has the ability to access. Level 2 classification may indicate that fair values have been determined using quoted prices in active markets but give effect to certain lock-up restrictions surrounding the holding period of the underlying investments. The fair value of level 3 investments held are derived from inputs that are unobservable and which reflect the limited partnerships' own determinations about the assumptions that market participants would use in pricing the investments, including assumptions about risk. These inputs are developed based on the partnership's own data, which is adjusted if information indicates that market participants would use different assumptions. The partnerships which invest directly into private equity portfolio companies (direct private equity funds) take into account various market conditions, subsequent rounds of financing, liquidity, financial condition, purchase multiples paid in other comparable third-party transactions, the price of securities of other companies comparable to the portfolio company, and operating results and other financial data of the portfolio company, as applicable. The partnerships which invest into other private equity funds take into account information received from those underlying funds, including their reported net asset values and evidence as to their fair value approach, including consistency of their fair value application. These investments do not trade in active markets and represent illiquid long-term investments that generally require future capital commitments. The partnerships' reported share of the underlying net asset values of the underlying funds is used as a practical expedient, as allowed by ASC Topic 820, in arriving at fair value. Quantitative Information about Level 3 Fair Value Measurements The following tables show significant unobservable inputs used in the fair value measurement of level 3 assets and liabilities at June 30, 2015 and December 31, 2014 : Assets and Liabilities * Fair Value at June 30, 2015 ($ in millions) Valuation Technique Unobservable Inputs Range Weighted Average (by fair value) Private Equity Funds --Equity Securities 256.1 Market Comparable Revenue Multiple 2 - 4x 3.1x Discount 25% 25.0% Published valuation and/or broker quotes for similar types of assets $26-100 million $49.3 million Assets and Liabilities * Fair Value at December 31, 2014 ($ in millions) Valuation Technique Unobservable Inputs Range Weighted Average (by fair value) Private Equity Funds --Equity Securities 273.2 Market Comparable Revenue Multiple 2 - 4x 4.0x Discount 25% - 36% 30.9% Published valuation and/or broker quotes for similar types of assets $27-104 million $45.9 million CLO Notes (5,149.6) Discounted Cash Flow- USD Assumed Default Rate*** 0.4% - 2.3% <1yr: 0.4% >1yr: 2.3% Spread over Libor ** 102 - 801bps 228 bps ____________ * Excluded from the table above are certain equity and debt securities held by consolidated private equity funds valued using recent private market transactions ( June 30, 2015 : $51.0 million ; December 31, 2014 : $85.0 million ) and third party appraisals ( June 30, 2015 : $1.0 million ; December 31, 2014 : $5.7 million ). At December 31, 2014 , certain tranches of the consolidated CLOs are valued using third party pricing information. Quantitative unobservable inputs for such valuations were not developed or adjusted by the company. Investments in other private equity funds as of June 30, 2015 of $403.6 million (as of December 31, 2014 : $410.0 million ) are also excluded from the table above as they are valued using the NAV practical expedient. The NAVs that have been provided are derived from the fair values of the underlying investments as of the consolidation date. ** Lower spreads relate to the more senior tranches in the CLO note structure; higher spreads relate to the less senior tranches. *** Assumed default rates listed in the table above apply to CLOs established prior to 2012. A default rate of 2.0% was assumed for CLOs established after January 1, 2012. The table below summarizes as of June 30, 2015 and December 31, 2014 , the nature of investments that are valued using the NAV as a practical expedient and any related liquidation restrictions or other factors which may impact the ultimate value realized: June 30, 2015 December 31, 2014 in millions, except term data Fair Value Total Unfunded Commitments Weighted Average Remaining Term (2) Fair Value Total Unfunded Commitments Weighted Average Remaining Term (2) Private equity funds (1) $403.6 $201.9 2.4 years $410.0 $196.3 2.6 years ____________ (1) These investments are not subject to redemption; however, for certain funds, the investors may sell or transfer their interest, which may require approval by the general partner of the underlying funds. (2) These investments are expected to be returned through distributions as a result of liquidations of the funds' underlying assets over the weighted average periods indicated. The following narrative will indicate the sensitivity of inputs illustrating the impact of significant increases to the inputs. An opposite impact would result for significant decreases in these inputs: • For investments held by consolidated private equity funds, significant increases in discounts in isolation would result in significantly lower fair value measurements, while significant increases in revenue multiple assumptions in isolation would result in significantly higher fair value measurements. An increase in discount assumptions would result in a directionally opposite change in the assumptions for revenue multiple resulting in lower fair value measurements.

Accounting Policies [Abstract]
Basis of Accounting and Consolidation	Basis of Accounting and Consolidation The unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with rules and regulations of the Securities and Exchange Commission. In the opinion of management, the financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for the fair statement 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 Condensed Consolidated Financial Statements have been prepared in accordance with U.S. GAAP and consolidate the financial statements of the Parent and all of its controlled subsidiaries.
Accounting Pronouncements Recently Adopted and Pending Accounting Pronouncements	Accounting Pronouncements Recently Adopted and Pending Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update 2014-09, "Revenue from Contracts with Customers" (ASU 2014-09), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 was originally effective for fiscal years and interim periods within those years beginning after December 15, 2016. In July 2015, the FASB voted to defer ASU 2014-09 by one year making it effective for fiscal years and interim periods within those years beginning after December 15, 2017. Early adoption is permitted as of the original effective date and requires either a retrospective or a modified retrospective approach to adoption. The company is currently evaluating the potential impact on its Consolidated Financial Statements, as well as the available transition methods. In August 2014, the FASB issued Accounting Standard Update 2014-13, "Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity" (ASU 2014-13). ASU 2014-13 provides a measurement alternative for an entity that consolidates a collateralized financing entity (CFE) and has elected the fair value option for the financial assets and financial liabilities of such CFE. The measurement alternative requires that the reporting entity measure both the financial assets and the financial liabilities of the CFE by using the more observable of the fair value of the financial assets and the fair value of the financial liabilities, removing any measurement difference previously recorded as net income (loss) attributable to noncontrolling interests in consolidated entities and as an adjustment to retained earnings appropriated for investors in CIP. On January 1, 2015 the company adopted ASU 2014-13 on a modified retrospective basis and has elected the measurement alternative for the consolidated CLOs. The adoption resulted in a $17.6 million reduction in retained earnings appropriated for investors in CIP, with a corresponding increase in debt of CIP. The company’s subsequent 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 will no longer be attributed to noncontrolling interests but will offset in other gains/(losses) of CIP. In February 2015, the FASB issued Accounting Standard Update 2015-02, “ Amendments to the Consolidation Analysis” (ASU 2015-02). This standard modifies existing consolidation guidance for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 is effective for fiscal years and interim periods within those years beginning after December 15, 2015, and requires either a retrospective or a modified retrospective approach to adoption. Early adoption is permitted. The company is currently evaluating the potential impact of this standard on its Consolidated Financial Statements, as well as the available transition methods. In April 2015, the FASB issued Accounting Standards Update 2015-03, "Simplifying the Presentation of Debt Issuance Costs" (ASU 2015-03), which changes the presentation of debt issuance costs in the balance sheet. ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability rather than being presented as an asset. Amortization of debt issuance costs will continue to be reported as interest expense. ASU 2015-03 is effective for fiscal years and interim periods within those years beginning after December 15, 2015, and requires retrospective application for each prior period presented. Early adoption is permitted. The company is currently evaluating the potential impact of this standard on its Consolidated Financial Statements. In May 2015, the FASB issued Accounting Standards Update 2015-07, "Fair Value Measurement - Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)" (ASU 2015-07). ASU 2015-07 removes the requirement to categorize investments within the fair value hierarchy for which fair value is measured using the net asset value practical expedient. ASU 2015-07 is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2015, and requires retrospective application for each prior period presented. Early adoption is permitted. While the company is still evaluating the impact of ASU 2015-07, adoption will not impact the company's financial condition, results of operations or cash flows, as the update relates to financial statement disclosures.
Fair Value Measurement	The following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy. Cash equivalents Cash investments in money market funds are valued under the market approach through the use of quoted market prices in an active market, which is the net asset value of the underlying funds, and are classified within level 1 of the valuation hierarchy. Available-for-sale investments Seed money is valued under the market approach through the use of quoted market prices available in an active market and is classified within level 1 of the valuation hierarchy; there is no modeling or additional information needed to arrive at the fair values of these investments. CLO assets are valued based on price quotations provided by an independent third-party pricing source or using an income approach through the use of certain observable and unobservable inputs. At June 30, 2015 and December 31, 2014 , investments in CLOs were valued using third-party pricing information. Due to liquidity constraints within the market for CLO products that require the use of unobservable inputs, these investments are classified within level 3 of the valuation hierarchy. Other debt securities are valued using a cost valuation technique due to the lack of available cash flow and market data and are accordingly also classified within level 3 of the valuation hierarchy. Trading investments • Investments related to deferred compensation plans Investments related to deferred compensation plans are valued under the market approach through the use of quoted prices in an active market and are classified within level 1 of the valuation hierarchy. • Seed money Seed money is valued under the market approach through the use of quoted market prices available in an active market and is classified within level 1 of the valuation hierarchy; there is no modeling or additional information needed to arrive at the fair values of these investments. • Other equity securities These securities are valued under the market approach through the use of quoted prices in an active market. To the extent these securities are actively traded, valuation adjustments are not applied and they are categorized within level 1 of the valuation hierarchy; otherwise, they are categorized in level 2. • UIT-related equity and debt securities The company invests in UIT-related equity and debt securities consisting of investments in corporate equities, UITs, and municipal securities. Each is discussed more fully below. Corporate equities The company temporarily holds investments in corporate equities for purposes of creating a UIT. Corporate equities are valued under the market approach through use of quoted prices on an exchange. To the extent these securities are actively traded, valuation adjustments are not applied and they are categorized within level 1 of the valuation hierarchy; otherwise, they are categorized in level 2. UITs The company may hold units of its sponsored UITs at period-end for sale in the primary market or secondary market. Equity UITs are valued under the market approach through use of quoted prices on an exchange. Fixed income UITs are valued using recently executed transaction prices, market price quotations (where observable), bond spreads, or credit default swap spreads. The spread data used is for the same maturities as the underlying bonds. If the spread data does not reference the issuers, then data that references comparable issuers is used. When observable price quotations are not available, fair value is determined based on cash flow models with yield curves, bond or single name credit default spreads, and recovery rates based on collateral value as key inputs. Depending on the nature of the inputs, these investments are categorized as level 1, 2, or 3. Municipal securities Municipal securities are valued using recently executed transaction prices, market price quotations (where observable), bond spreads, or credit default swap spreads. The spread data used is for the same maturities as the underlying bonds. If the spread data does not reference the issuers, then data that references comparable issuers is used. When observable price quotations are not available, fair value is determined based on cash flow models with yield curves, bond or single name credit default spreads, and recovery rates based on collateral value as key inputs. Depending on the nature of the inputs, these investments are categorized as level 1, 2, or 3. Put option contracts The company has purchased several put option contracts to hedge economically foreign currency risk on the translation of a portion of its pound sterling-denominated earnings into U.S. dollars (purchases of $2.4 million and $9.2 million in the three and six months ended June 30, 2015 , respectively). These were the only contracts entered into during the period to hedge economically foreign currency risk and provide coverage through March 31, 2016 . The economic hedge is predominantly triggered upon the impact of a significant decline in the pound sterling/U.S. dollar foreign exchange rate, which could arise as a result of European economic uncertainty. Open put option contracts are marked-to-market through earnings, which are recorded in the company's Condensed Consolidated Statements of Income in other gains and losses. These derivative contracts are valued using option valuation models and are included in other assets in the company's Condensed Consolidated Balance Sheets. The significant inputs in these models (volatility, forward points and swap curves) are readily available in public markets or can be derived from observable market transactions for substantially the full terms of the contracts and are classified within level 2 of the valuation hierarchy. The company recognized losses of $8.4 million and $7.8 million in the three and six months ended June 30, 2015 , respectively (three and six months ended June 30, 2014 : none ) related to the change in market value of these put option contracts. Assets held for policyholders Assets held for policyholders are measured at fair value under the market approach based on the quoted prices of the underlying funds in an active market and are classified within level 1 of the valuation hierarchy. The policyholder payables are indexed to the value of the assets held for policyholders and are therefore not included in the tables below. UIT-related financial instruments sold, not yet purchased, and derivative instruments The company uses U.S. Treasury futures, which are types of derivative financial instruments, to hedge economically fixed income UIT inventory and securities in order to mitigate market risk. Open futures contracts are marked-to-market daily through earnings, which are recorded in the company’s Condensed Consolidated Statements of Income in other revenue, along with the mark-to-market on the underlying trading securities held. Fair values of derivative contracts in an asset position are included in other assets in the company’s Condensed Consolidated Balance Sheets. Fair values of derivative contracts in a liability position are included in other liabilities in the company’s Condensed Consolidated Balance Sheets. These derivative contracts are valued under the market approach through use of quoted prices in an active market and are classified within level 1 of the valuation hierarchy. At June 30, 2015 there were 23 futures contracts with a notional value of $3.2 million ( December 31, 2014 : 6 open futures contracts with a notional value of $0.8 million ). Additionally, to hedge economically the market risk associated with equity and debt securities and UITs temporarily held as trading investments, the company will hold short corporate equities, exchange-traded funds, or U.S. treasury security positions. These transactions are recorded as financial instruments sold, not yet purchased and are included in accounts payable and accrued expenses in the company’s Condensed Consolidated Balance Sheets. To the extent these securities are actively traded, valuation adjustments are not applied and they are categorized within level 1 of the valuation hierarchy; otherwise, they are categorized in level 2. Contingent Consideration Liability During the six months ended June 30, 2015 , the company acquired certain investment management contracts from a third party. Indefinite-lived intangible assets were valued at $119.3 million . This transaction was a non-cash investing activity during the period. The purchase price was comprised solely of contingent consideration payable in future periods, and is linked to future revenues generated from the contracts. The contingent consideration liability was recorded at fair value as of the date of acquisition using a discounted cash flow model, and is categorized within level 3 of the valuation hierarchy. Anticipated future cash flows were determined using forecast AUM levels and discounted back to the valuation date using a discount rate of 3.4% . Assumed growth rates in AUM ranged from 0% to 5% (weighted average growth rate of 2.89% ). The company reassesses significant unobservable inputs during each reporting period. Changes in fair value are recorded in Other gains and losses, net in the Condensed Consolidated Statements of Income in the period incurred. An increase in AUM levels and a decrease in the discount rate would increase the fair value of the contingent consideration liability while a decrease in forecasted AUM and an increase in the discount rate would decrease the liability.

Beyond these items, there are no other restrictive covenants in the indentures. The issuer of the senior notes is an indirect 100% owned finance subsidiary of Invesco Ltd. (the Parent), and the Parent fully and unconditionally guaranteed the securities. The requirement of certain subsidiaries of the Parent to maintain minimum levels of capital and other similar provisions of applicable law may have the effect of limiting withdrawals of capital, repayment of intercompany loans and payment of dividends by such entities. The fair market value of the company's senior notes was determined by market quotes provided by Bloomberg, which is considered a Level 2 valuation input. In the absence of an active market, the company relies upon the average price quoted by brokers for determining the fair market value of the debt.
Analysis Of Borrowings By Maturity	At June 30, 2015 , the company's outstanding senior notes of $1,589.6 million mature in periods greater than five years from the balance sheet date.
Schedule of Line of Credit Facilities	At June 30, 2015 , the outstanding balance on the $1.25 billion credit facility was $7.9 million ( December 31, 2014 : zero ). The credit facility has a maturity of December 17, 2018. Borrowings under the credit facility will bear interest at (i) LIBOR for specified interest periods or (ii) a floating base rate (based upon the highest of (a) the Bank of America prime rate, (b) the Federal Funds rate plus 0.50% and (c) LIBOR for an interest period of one month plus 1.00% ), plus, in either case, an applicable margin determined with reference to the higher of the available credit ratings of the company or its indirect subsidiary Invesco Finance PLC. Based on credit ratings as of June 30, 2015 of the company, the applicable margin for LIBOR-based loans was 1.00% and for base rate loans was 0.00% . In addition, the company is required to pay the lenders a facility fee on the aggregate commitments of the lenders (whether or not used) at a rate per annum which is based on the higher of the available credit ratings of the company or its indirect subsidiary Invesco Finance PLC. Based on credit ratings as of June 30, 2015 , the annual facility fee was equal to 0.125% . The credit agreement governing the credit facility contains customary restrictive covenants on the company and its subsidiaries. Restrictive covenants in the credit agreement include, but are not limited to: prohibitions on creating, incurring or assuming any liens; entering into merger arrangements; selling, leasing, transferring or otherwise disposing of assets; making a material change in the nature of the business; making a significant accounting policy change in certain situations; entering into transactions with affiliates; and incurring indebtedness through the subsidiaries. Many of these restrictions are subject to certain minimum thresholds and exceptions. Financial covenants under the credit agreement include: (i) the quarterly maintenance of a debt/EBITDA leverage ratio, as defined in the credit agreement, of not greater than 3.25 :1.00, (ii) a coverage ratio (EBITDA, as defined in the credit agreement/interest payable for the four consecutive fiscal quarters ended before the date of determination) of not less than 4.00 :1.00. The credit agreement governing the credit facility also contains customary provisions regarding events of default which could result in an acceleration or increase in amounts due, including (subject to certain materiality thresholds and grace periods) payment default, failure to comply with covenants, material inaccuracy of representation or warranty, bankruptcy or insolvency proceedings, change of control, certain judgments, ERISA matters, cross-default to other debt agreements, governmental action prohibiting or restricting the company or its subsidiaries in a manner that has a material adverse effect and failure of certain guaranty obligations. The company is in compliance with all regulatory minimum net capital requirements. The lenders (and their respective affiliates) may have provided, and may in the future provide, investment banking, cash management, underwriting, lending, commercial banking, leasing, foreign exchange, trust or other advisory services to the company and its subsidiaries and affiliates. These parties may have received, and may in the future receive, customary compensation for these services. The company maintains approximately $33.4 million in letters of credit from a variety of banks. The letters of credit are generally one -year automatically-renewable facilities and are maintained for various commercial reasons.
