Organization, Consolidation and Presentation of Financial Statements [Abstract]
Formation of the Entity and Basis of Presentation	Formation of the Entity and Basis of Presentation The Western Union Company ("Western Union" or the "Company") is a leader in global money movement and payment services, providing people and businesses with fast, reliable and convenient ways to send money and make payments around the world. The Western Union ® brand is globally recognized. The Company's services are primarily available through a network of agent locations in more than 200 countries and territories. Each location in the Company's agent network is capable of providing one or more of the Company's services. The Western Union business consists of the following segments: • Consumer-to-Consumer - The Consumer-to-Consumer operating segment facilitates money transfers between two consumers, primarily through a network of third-party agents. The Company's multi-currency, real-time money transfer service is viewed by the Company as one interconnected global network where a money transfer can be sent from one location to another, around the world. This service is available for international cross-border transfers - that is, the transfer of funds from one country to another - and, in certain countries, intra-country transfers - that is, money transfers from one location to another in the same country. This segment also includes money transfer transactions that can be initiated through websites, mobile devices and account based money transfers. • Consumer-to-Business - The Consumer-to-Business operating segment facilitates bill payments from consumers to businesses and other organizations, including utilities, auto finance companies, mortgage servicers, financial service providers, government agencies and other businesses. The significant majority of the segment's revenue was generated in the United States during all periods presented, with the remainder primarily generated in Argentina. • Business Solutions - The Business Solutions operating segment facilitates payment and foreign exchange solutions, primarily cross-border, cross-currency transactions, for small and medium size enterprises and other organizations and individuals. The majority of the segment's business relates to exchanges of currency at spot rates, which enable customers to make cross-currency payments. In addition, in certain countries, the Company writes foreign currency forward and option contracts for customers to facilitate future payments. All businesses that have not been classified in the above segments are reported as "Other" and include the Company's money order and other services, in addition to costs for the review and closing of acquisitions. There are legal or regulatory limitations on transferring certain assets of the Company outside of the countries where these assets are located. However, there are generally no limitations on the use of these assets within those countries. Additionally, the Company must meet minimum capital requirements in some countries in order to maintain operating licenses. As of December 31, 2015 , the amount of net assets subject to these limitations totaled approximately $300 million . Various aspects of the Company's services and businesses are subject to United States federal, state and local regulation, as well as regulation by foreign jurisdictions, including certain banking and other financial services regulations. Spin-off from First Data On January 26, 2006, the First Data Corporation ("First Data") Board of Directors announced its intention to pursue the distribution of all of its money transfer and consumer payments businesses and its interest in a Western Union money transfer agent, as well as its related assets, including real estate, through a tax-free distribution to First Data shareholders (the "Spin-off"). Effective on September 29, 2006, First Data completed the separation and the distribution of these businesses by distributing The Western Union Company common stock to First Data shareholders (the "Distribution"). Prior to the Distribution, the Company had been a segment of First Data. Basis of Presentation The financial statements in this Annual Report on Form 10-K are presented on a consolidated basis and include the accounts of the Company and its majority-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated. Consistent with industry practice, the accompanying Consolidated Balance Sheets are unclassified due to the short-term nature of the Company's settlement obligations contrasted with the Company's ability to invest cash awaiting settlement in long-term investment securities.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. Principles of Consolidation The Company consolidates financial results when it has both the power to direct the activities of an entity that most significantly impact the entity's economic performance and the ability to absorb losses or the right to receive benefits of the entity that could potentially be significant to the entity. The Company utilizes the equity method of accounting when it is able to exercise significant influence over the entity's operations, which generally occurs when the Company has an ownership interest of between 20% and 50% in an entity. Earnings Per Share The calculation of basic earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Outstanding options to purchase Western Union stock and unvested shares of restricted stock are excluded from basic shares outstanding. Diluted earnings per share reflects the potential dilution that could occur if outstanding stock options at the presented dates are exercised and shares of restricted stock have vested, using the treasury stock method. The treasury stock method assumes proceeds from the exercise price of stock options, the unamortized compensation expense and assumed tax benefits of options and restricted stock are available to acquire shares at an average market price throughout the period, and therefore, reduce the dilutive effect. For the years ended December 31, 2015 , 2014 and 2013 , there were 6.0 million , 15.5 million and 21.2 million , respectively, of outstanding options to purchase shares of Western Union stock excluded from the diluted earnings per share calculation, as their effect was anti-dilutive. The following table provides the calculation of diluted weighted-average shares outstanding (in millions): For the Year Ended December 31, 2015 2014 2013 Basic weighted-average shares outstanding 512.6 533.4 556.6 Common stock equivalents 4.1 3.4 3.1 Diluted weighted-average shares outstanding 516.7 536.8 559.7 Fair Value Measurements The Company determines the fair values of its assets and liabilities that are recognized or disclosed at fair value in accordance with the hierarchy described below. The fair values of the assets and liabilities held in the Company's defined benefit plan trust ("Trust") are recognized or disclosed utilizing the same hierarchy. The following three levels of inputs may be used to measure fair value: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. For most of these assets, the Company utilizes pricing services that use multiple prices as inputs to determine daily market values. In addition, the Trust has other investments that fall within Level 2 that are valued at net asset value which is not quoted on an active market; however, the unit price is based on underlying investments which are traded on an active market. The individual redemption restrictions of Trust investments measured at net asset value are also considered when determining whether Level 2 classification is appropriate. • Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include items where the determination of fair value requires significant management judgment or estimation. The Company has Level 3 assets that are recognized and disclosed at fair value on a non-recurring basis related to the Company's business combinations, where the values of the intangible assets and goodwill acquired in a purchase are derived utilizing one of the three recognized approaches: the market approach, the income approach or the cost approach. Carrying amounts for many of the Company's financial instruments, including cash and cash equivalents, settlement cash and cash equivalents, and settlement receivables and settlement obligations approximate fair value due to their short maturities. Investment securities and derivative financial instruments are carried at fair value and included in Note 8. Fixed rate notes are carried at their original issuance values as adjusted over time to accrete that value to par, except for portions of notes hedged by interest rate swap agreements as disclosed in Note 14. The fair values of fixed rate notes are also disclosed in Note 8 and are based on market quotations. For more information on the fair value of financial instruments, see Note 8. The fair values of non-financial assets and liabilities related to the Company's business combinations are disclosed in Note 4. Business Combinations The Company accounts for all business combinations where control over another entity is obtained using the acquisition method of accounting, which requires that most assets (both tangible and intangible), liabilities (including contingent consideration), and remaining noncontrolling interests be recognized at fair value at the date of acquisition. The excess of the purchase price over the fair value of assets less liabilities and noncontrolling interests is recognized as goodwill. Certain adjustments to the assessed fair values of the assets, liabilities, or noncontrolling interests made subsequent to the acquisition date, but within the measurement period, which is one year or less, are recorded as adjustments to goodwill. Any adjustments subsequent to the measurement period are recorded in income. Any cost or equity method interest that the Company holds in the acquired company prior to the acquisition is remeasured to fair value at acquisition with a resulting gain or loss recognized in income for the difference between fair value and existing book value. Results of operations of the acquired company are included in the Company's results from the date of the acquisition forward and include amortization expense arising from acquired intangible assets. The Company expenses all costs as incurred related to or involved with an acquisition in "Selling, general and administrative" expenses. Cash and Cash Equivalents Highly liquid investments (other than those included in settlement assets) with maturities of three months or less at the date of purchase (that are readily convertible to cash) are considered to be cash equivalents and are stated at cost, which approximates fair value. The Company maintains cash and cash equivalent balances, including a portion in money market funds, with a group of globally diversified banks and financial institutions. The Company limits the concentration of its cash and cash equivalents with any one institution and regularly reviews investment concentrations and credit worthiness of these institutions. Allowance for Doubtful Accounts The Company records an allowance for doubtful accounts when it is probable that the related receivable balance will not be collected based on its history of collection experience, known collection issues, such as agent suspensions and bankruptcies, consumer chargebacks and insufficient funds, and other matters the Company identifies in its routine collection monitoring. The allowance for doubtful accounts was $41.1 million and $37.2 million as of December 31, 2015 and 2014 , respectively, and is recorded in the same Consolidated Balance Sheet caption as the related receivable. During the years ended December 31, 2015 , 2014 and 2013 , the provision for doubtful accounts (bad debt expense) reflected in the Consolidated Statements of Income was $60.3 million , $50.7 million and $50.1 million , respectively. Settlement Assets and Obligations Settlement assets represent funds received or to be received from agents for unsettled money transfers, money orders and consumer payments. The Company records corresponding settlement obligations relating to amounts payable under money transfers, money orders and consumer payment service arrangements. Settlement assets and obligations also include amounts receivable from, and payable to, customers for the value of their cross-currency payment transactions related to the Business Solutions segment. Settlement assets consist of cash and cash equivalents, receivables from selling agents and Business Solutions customers, and investment securities. Cash received by Western Union agents generally becomes available to the Company within one week after initial receipt by the agent. Cash equivalents consist of short-term time deposits, commercial paper and other highly liquid investments. Receivables from selling agents represent funds collected by such agents, but in transit to the Company. Western Union has a large and diverse agent base, thereby reducing the credit risk of the Company from any one agent. In addition, the Company performs ongoing credit evaluations of its agents' financial condition and credit worthiness. See Note 7 for information concerning the Company's investment securities. Receivables from Business Solutions customers arise from cross-currency payment transactions in the Business Solutions segment. Receivables occur when funds have been paid out to a beneficiary but not yet received from the customer. Aside from these receivables, the credit risk associated with spot foreign currency exchange contracts is largely mitigated, as in most cases the Company requires the receipt of funds from customers before releasing the associated cross-currency payment. Settlement obligations consist of money transfer, money order and payment service payables and payables to agents. Money transfer payables represent amounts to be paid to transferees when they request their funds. Most agents typically settle with transferees first and then obtain reimbursement from the Company. Money order payables represent amounts not yet presented for payment. Payment service payables represent amounts to be paid to utility companies, auto finance companies, mortgage servicers, financial service providers, government agencies and others. Due to the agent funding and settlement process, payables to agents represent amounts due to agents for money transfers that have been settled with transferees. Settlement assets and obligations consisted of the following (in millions): December 31, 2015 2014 Settlement assets: Cash and cash equivalents $ 1,075.7 $ 834.3 Receivables from selling agents and Business Solutions customers 1,070.4 1,006.9 Investment securities 1,162.6 1,472.5 $ 3,308.7 $ 3,313.7 Settlement obligations: Money transfer, money order and payment service payables $ 2,428.5 $ 2,356.7 Payables to agents 880.2 957.0 $ 3,308.7 $ 3,313.7 Property and Equipment Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the lesser of the estimated life of the related assets (generally three to ten years for equipment and furniture and fixtures, and 30 years for buildings) or the lease term. Maintenance and repairs, which do not extend the useful life of the respective assets, are charged to expense as incurred. Property and equipment consisted of the following (in millions): December 31, 2015 2014 Equipment $ 529.8 $ 464.6 Buildings 87.3 87.8 Leasehold improvements 83.3 81.1 Furniture and fixtures 39.6 32.2 Land and improvements 17.0 17.0 Projects in process 13.0 2.2 Total property and equipment, gross 770.0 684.9 Less accumulated depreciation (538.2 ) (478.5 ) Property and equipment, net $ 231.8 $ 206.4 Amounts charged to expense for depreciation of property and equipment were $67.7 million , $66.6 million and $64.2 million during the years ended December 31, 2015 , 2014 and 2013 , respectively. Goodwill Goodwill represents the excess of purchase price over the fair value of tangible and other intangible assets acquired, less liabilities assumed arising from business combinations. The Company's annual impairment assessment did not identify any goodwill impairment during the years ended December 31, 2015 , 2014 and 2013 . Other Intangible Assets Other intangible assets primarily consist of acquired contracts, contract costs (primarily amounts paid to agents in connection with establishing and renewing long-term contracts) and software. Other intangible assets are amortized on a straight-line basis over the length of the contract or benefit periods. Included in the Consolidated Statements of Income is amortization expense of $202.5 million , $205.3 million and $198.6 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Acquired contracts include customer and contractual relationships and networks of subagents that are recognized in connection with the Company's acquisitions. The Company capitalizes initial payments for new and renewed agent contracts to the extent recoverable through future operations or penalties in the case of early termination. The Company's accounting policy is to limit the amount of capitalized costs for a given contract to the lesser of the estimated future cash flows from the contract or the termination fees the Company would receive in the event of early termination of the contract. The Company purchases and develops software that is used in providing services and in performing administrative functions. Software development costs are capitalized once technological feasibility of the software has been established. Costs incurred prior to establishing technological feasibility are expensed as incurred. Technological feasibility is established when the Company has completed all planning and designing activities that are necessary to determine that a product can be produced to meet its design specifications, including functions, features and technical performance requirements. Capitalization of costs ceases when the product is available for general use. Software development costs and purchased software are generally amortized over a term of three to five years. The following table provides the components of other intangible assets (in millions): December 31, 2015 December 31, 2014 Weighted- Average Amortization Period (in years) Initial Cost Net of Accumulated Amortization Initial Cost Net of Accumulated Amortization Acquired contracts 11.3 $ 624.4 $ 316.6 $ 630.8 $ 374.9 Capitalized contract costs 5.9 541.2 290.4 559.6 276.6 Internal use software 3.2 338.1 53.8 301.6 60.1 Acquired trademarks 24.5 34.7 20.2 36.4 22.7 Projects in process 3.0 23.5 23.5 12.2 12.2 Other intangibles 4.1 27.5 0.5 27.5 1.6 Total other intangible assets 7.8 $ 1,589.4 $ 705.0 $ 1,568.1 $ 748.1 The estimated future aggregate amortization expense for existing other intangible assets as of December 31, 2015 is expected to be $183.9 million in 2016, $153.7 million in 2017, $118.2 million in 2018, $82.1 million in 2019, $63.0 million in 2020 and $ 104.1 million thereafter. Other intangible assets are reviewed for impairment on an annual basis or whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. In such reviews, estimated undiscounted cash flows associated with these assets or operations are compared with their carrying values to determine if a write-down to fair value (normally measured by the present value technique) is required. The Company recorded immaterial impairments related to other intangible assets during the years ended December 31, 2015 , 2014 and 2013 . Revenue Recognition The Company's revenues are primarily derived from consumer money transfer transaction fees that are based on the principal amount of the money transfer and the locations from and to which funds are transferred. The Company also offers several payments services, including payments from consumers or businesses to other businesses. Transaction fees are set by the Company and recorded as revenue at the time of sale. In certain consumer money transfer, bill payment and Business Solutions transactions involving different send and receive currencies, the Company generates revenue based on the difference between the exchange rate set by the Company to the consumer or business and the rate at which the Company or its agents are able to acquire the currency. This foreign exchange revenue is recorded at the time the related consumer money transfer transaction fee revenue is recognized or at the time a customer initiates a transaction through the Company's Business Solutions payment service operations. Cost of Services Cost of services primarily consists of agent commissions and expenses for call centers, settlement operations and related information technology costs. Expenses within these functions include personnel, software, equipment, telecommunications, bank fees, depreciation, amortization and other expenses incurred in connection with providing money transfer and other payment services. Advertising Costs Advertising costs are charged to operating expenses as incurred. Advertising costs for the years ended December 31, 2015 , 2014 and 2013 were $166.3 million , $162.7 million and $165.1 million , respectively. Income Taxes The Company accounts for income taxes under the liability method, which requires that deferred tax assets and liabilities be determined based on the expected future income tax consequences of events that have been recognized in the consolidated financial statements. Deferred tax assets and liabilities are recognized based on temporary differences between the financial statement carrying amounts and tax bases of assets and liabilities using enacted tax rates in effect in the years in which the temporary differences are expected to reverse. The Company assesses the realizability of its deferred tax assets. A valuation allowance must be established when, based upon available evidence, it is more likely than not that all or a portion of the deferred tax assets will not be realized. The Company recognizes the tax benefits from uncertain tax positions only when it is more likely than not, based on the technical merits of the position, the tax position will be sustained upon examination, including the resolution of any related appeals or litigation. The tax benefits recognized in the consolidated financial statements from such a position are measured as the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. Foreign Currency Translation The United States dollar is the functional currency for substantially all of the Company's businesses. Revenues and expenses are translated at average exchange rates prevailing during the period. Foreign currency denominated assets and liabilities for those businesses for which the local currency is the functional currency are translated into United States dollars based on exchange rates at the end of the year. The effects of foreign exchange gains and losses arising from the translation of assets and liabilities of these businesses are included as a component of "Accumulated other comprehensive loss" in the accompanying Consolidated Balance Sheets. Foreign currency denominated monetary assets and liabilities of businesses for which the United States dollar is the functional currency are remeasured based on exchange rates at the end of the period, and the resulting remeasurement gains and losses are recognized in net income. Non-monetary assets and liabilities of these operations are remeasured at historical rates in effect when the asset was recognized or the liability was incurred. Derivatives The Company uses derivatives to (a) minimize its exposures related to changes in foreign currency exchange rates and interest rates and (b) facilitate cross-currency Business Solutions payments by writing derivatives to customers. The Company recognizes all derivatives in the "Other assets" and "Other liabilities" captions in the accompanying Consolidated Balance Sheets at their fair value. All cash flows associated with derivatives are included in cash flows from operating activities in the Consolidated Statements of Cash Flows. • Cash flow hedges - Changes in the fair value of derivatives that are designated and qualify as cash flow hedges are recorded in "Accumulated other comprehensive loss." Cash flow hedges consist of foreign currency hedging of forecasted revenues, as well as hedges of the forecasted issuance of fixed rate debt. Derivative fair value changes that are captured in "Accumulated other comprehensive loss" are reclassified to earnings in the same period or periods the hedged item affects earnings, to the extent the instrument is effective in offsetting the change in cash flows attributable to the risk being hedged. The portions of the change in fair value that are either considered ineffective or are excluded from the measure of effectiveness are recognized immediately in "Derivative gains/(losses), net." • Fair value hedges - Changes in the fair value of derivatives that are designated as fair value hedges of fixed rate debt are recorded in "Interest expense." The offsetting change in value of the related debt instrument attributable to changes in the benchmark interest rate is also recorded in "Interest expense." • Undesignated - Derivative contracts entered into to reduce the variability related to (a) money transfer settlement assets and obligations, generally with maturities from a few days up to one month, and (b) certain foreign currency denominated cash and other asset and liability positions, typically with maturities of less than one year at inception, are not designated as hedges for accounting purposes and changes in their fair value are included in "Selling, general and administrative." The Company is also exposed to risk from derivative contracts written to its customers arising from its cross-currency Business Solutions payments operations. The duration of these derivative contracts at inception is generally less than one year. The Company aggregates its Business Solutions payments foreign currency exposures arising from customer contracts, including the derivative contracts described above, and hedges the resulting net currency risks by entering into offsetting contracts with established financial institution counterparties (economic hedge contracts) as part of a broader foreign currency portfolio, including significant spot exchanges of currency in addition to forwards and options. The changes in fair value related to these contracts are recorded in "Foreign exchange revenues." The fair value of the Company's derivatives is derived from standardized models that use market based inputs (e.g., forward prices for foreign currency). The details of each designated hedging relationship are formally documented at the inception of the arrangement, including the risk management objective, hedging strategy, hedged item, specific risks being hedged, the derivative instrument, how effectiveness is being assessed and how ineffectiveness, if any, will be measured. The derivative must be highly effective in offsetting the changes in cash flows or fair value of the hedged item, and effectiveness is evaluated quarterly on a retrospective and prospective basis. Legal Contingencies The Company is a party to certain legal and regulatory proceedings with respect to a variety of matters. The Company records an accrual for these contingencies to the extent that a loss is both probable and reasonably estimable. If some amount within a range of loss appears to be a better estimate than any other amount within the range, that amount is accrued. When no amount within a range of loss appears to be a better estimate than any other amount, the lowest amount in the range is accrued. Stock-Based Compensation The Company currently has a stock-based compensation plan that provides for grants of Western Union stock options, restricted stock awards and restricted and unrestricted stock units to employees and non-employee directors of the Company. All stock-based compensation to employees is required to be measured at fair value and expensed over the requisite service period and also requires an estimate of forfeitures when calculating compensation expense. The Company recognizes compensation expense on awards on a straight-line basis over the requisite service period for the entire award. Refer to Note 16 for additional discussion regarding details of the Company's stock-based compensation plans. Severance and Other Related Expenses The Company records severance-related expenses once they are both probable and estimable in accordance with the provisions of the applicable accounting guidance for severance provided under an ongoing benefit arrangement. One-time, involuntary benefit arrangements and other costs are generally recognized when the liability is incurred. The Company also evaluates impairment issues associated with restructuring and other activities when the carrying amount of the assets may not be fully recoverable, in accordance with the appropriate accounting guidance. New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board issued a new accounting pronouncement regarding revenue from contracts with customers. This new standard provides guidance on recognizing revenue, including a five step model to determine when revenue recognition is appropriate. The standard requires that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company is required to adopt the new standard on January 1, 2018. Management is currently evaluating the potential impact that the adoption of this standard will have on the Company's financial position, results of operations, and related disclosures. In April 2015, the Financial Accounting Standards Board issued guidance on the financial statement presentation of debt issuance costs. This update requires capitalized debt issuance costs to be presented as a reduction to the carrying value of debt instead of being classified as a deferred charge, as currently required. The Company is required to adopt the new standard on January 1, 2016, with adoption retroactive for all periods presented. This update will not have a material impact on the presentation of the Company’s financial position, results of operations, and related disclosures. In January 2016, the Financial Accounting Standards Board issued a new accounting pronouncement regarding classification and measurement of financial instruments. This new standard provides guidance on how entities measure certain equity investments and present changes in the fair value. This standard requires that entities measure certain equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income. The Company is required to adopt the new standard on January 1, 2018. Management is currently evaluating the potential impact that the adoption of this standard will have on the Company's financial position, results of operations, and related disclosures.

Productivity and Cost-Savings Initiatives Expenses [Abstract]
Productivity and Cost-Savings Initiatives Expenses	Productivity and Cost-Savings Initiatives Expenses During the years ended December 31, 2015, 2014 and 2013, the Company implemented initiatives to improve productivity and reduce costs. A significant majority of the productivity and cost-savings initiatives costs relate to severance and related expenses, including termination benefits received by certain of the Company's former executives. During the years ended December 31, 2015, 2014 and 2013, the Company incurred $11.1 million , $30.3 million , and $56.9 million , respectively, of expenses related to productivity and cost-savings initiatives. During the years ended December 31, 2015, 2014 and 2013, the Company made cash payments of $30.0 million , $42.9 million and $41.8 million , respectively, related to productivity and cost-savings initiatives. The following table presents the above expenses related to productivity and cost-savings initiatives as reflected in the Consolidated Statements of Income (in millions): Year Ended December 31, 2015 2014 2013 Cost of services $ 1.0 $ 11.6 $ 24.3 Selling, general and administrative 10.1 18.7 32.6 Total expenses, pre-tax $ 11.1 $ 30.3 $ 56.9 Total expenses, net of tax $ 7.2 $ 20.2 $ 40.2 The following table summarizes the above expenses incurred by reportable segment (in millions): Consumer-to-Consumer Consumer-to-Business Business Solutions Other Total 2013 expenses $ 43.8 $ 5.4 $ 3.6 $ 4.1 $ 56.9 2014 expenses 15.7 6.7 7.3 0.6 30.3 2015 expenses 7.6 1.5 1.8 0.2 11.1 As of December 31, 2015 and 2014, amounts remaining to be paid related to productivity and cost-savings initiatives were $14.7 million and $33.6 million , respectively.

Business Combinations [Abstract]
Acquisitions	Acquisitions During the first quarter of 2014, the Company acquired the Brazilian retail, walk-in foreign exchange operations of Fitta DTVM S.A. and Fitta Turismo Ltda. for total consideration of $18.5 million . Of the total consideration, $15.6 million was allocated to identifiable intangible assets, the majority of which relates to contractual relationships. The identifiable intangible assets are being amortized over a period of two to twelve years with a weighted average life of ten years. The Company recognized $2.4 million of goodwill related to this acquisition. The valuation of assets acquired was derived primarily using unobservable Level 3 inputs, which require significant management judgment and estimation. The following table presents changes to goodwill for the years ended December 31, 2015 and 2014 (in millions): Consumer-to-Consumer Consumer-to-Business Business Solutions Other Total January 1, 2014 balance $ 1,947.7 $ 214.7 $ 996.0 $ 13.6 $ 3,172.0 Acquisitions 2.4 — — — 2.4 Currency translation — (5.0 ) — (0.2 ) (5.2 ) December 31, 2014 balance $ 1,950.1 $ 209.7 $ 996.0 $ 13.4 $ 3,169.2 Currency translation — (5.2 ) — (0.2 ) (5.4 ) December 31, 2015 balance $ 1,950.1 $ 204.5 $ 996.0 $ 13.2 $ 3,163.8

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Letters of Credit and Bank Guarantees The Company had approximately $85 million in outstanding letters of credit and bank guarantees as of December 31, 2015 . The letters of credit and bank guarantees are primarily held in connection with lease arrangements and certain agent agreements. The letters of credit and bank guarantees have expiration dates through 2020 , with many having a one -year renewal option. The Company expects to renew the letters of credit and bank guarantees prior to expiration in most circumstances. Litigation and Related Contingencies The Company is subject to certain claims and litigation that could result in losses, including damages, fines and/or civil penalties, which could be significant, and in some cases, criminal charges. The Company regularly evaluates the status of legal matters to assess whether a loss is probable and reasonably estimable in determining whether an accrual is appropriate. Furthermore, in determining whether disclosure is appropriate, the Company evaluates each legal matter to assess if there is at least a reasonable possibility that a loss or additional loss may have been incurred and whether an estimate of possible loss or range of loss can be made. Unless otherwise specified below, the Company believes that there is at least a reasonable possibility that a loss or additional loss may have been incurred for each of the matters described below. For certain of these matters, management is unable to provide a meaningful estimate of the possible loss or range of loss because, among other reasons: (a) the proceedings are in preliminary stages; (b) specific damages have not been sought; (c) damage claims are unsupported and/or unreasonable; (d) there is uncertainty as to the outcome of pending appeals or motions; (e) there are significant factual issues to be resolved; or (f) novel legal issues or unsettled legal theories are being asserted. State of Arizona Settlement Agreement On February 11, 2010, Western Union Financial Services, Inc. ("WUFSI"), a subsidiary of the Company, signed a settlement agreement ("Southwest Border Agreement"), which resolved all outstanding legal issues and claims with the State of Arizona (the "State") and required the Company to fund a multi-state not-for-profit organization promoting safety and security along the United States and Mexico border, in which California, Texas and New Mexico are participating with Arizona. As part of the Southwest Border Agreement, the Company has made and expects to make certain investments in its compliance programs along the United States and Mexico border and a monitor (the "Monitor") has been engaged for those programs. The Company has incurred, and expects to continue to incur, significant costs in connection with the Southwest Border Agreement. The Monitor has made a number of recommendations related to the Company's compliance programs, which the Company is implementing, including programs related to the Company's Business Solutions segment. On January 31, 2014, the Southwest Border Agreement was amended to extend its term until December 31, 2017 (the "Amendment"). The Amendment imposes additional obligations on the Company and WUFSI in connection with WUFSI’s anti-money laundering ("AML") compliance programs and cooperation with law enforcement. In particular, the Amendment requires WUFSI to continue implementing the primary and secondary recommendations made by the Monitor appointed pursuant to the Southwest Border Agreement related to WUFSI’s AML compliance program, and includes, among other things, timeframes for implementing such primary and secondary recommendations. Under the Amendment, the Monitor could make additional primary recommendations until January 1, 2015 and may make additional secondary recommendations until January 31, 2017. After these dates, the Monitor may only make additional primary or secondary recommendations, as applicable, that meet certain requirements as set forth in the Amendment. Primary recommendations may also be re-classified as secondary recommendations. The Amendment provides that if WUFSI is unable to implement an effective AML compliance program along the U.S. and Mexico border, as determined by the Monitor and subject to limited judicial review, within the timeframes to implement the Monitor’s primary recommendations, the State may, within 180 days after the Monitor delivers its final report on the primary recommendations on December 31, 2016, and subsequent to any judicial review of the Monitor’s findings, elect one , and only one, of the following remedies: (i) assert a willful and material breach of the Southwest Border Agreement and pursue remedies under the Southwest Border Agreement, which could include initiating civil or criminal actions; or (ii) require WUFSI to pay (a) $50 million plus (b) $1 million per primary recommendation or group of primary recommendations that WUFSI fails to implement successfully. There are currently more than 70 primary recommendations and groups of primary recommendations. If the Monitor concludes that WUFSI has implemented an effective AML compliance program along the U.S. and Mexico border within the timeframes to implement the Monitor’s primary recommendations, the State cannot pursue either of the remedies above, except that the State may require WUFSI to pay $1 million per primary recommendation or group of primary recommendations that WUFSI fails to implement successfully. If, at the conclusion of the timeframe to implement the secondary recommendations on December 31, 2017, the Monitor concludes that WUFSI has not implemented an effective AML compliance program along the U.S. and Mexico border, the State cannot assert a willful and material breach of the Southwest Border Agreement but may require WUFSI to pay an additional $25 million . Additionally, if the Monitor determines that WUFSI has implemented an effective AML compliance program along the U.S. and Mexico border but has not implemented some of the Monitor’s secondary recommendations or groups of secondary recommendations that were originally classified as primary recommendations or groups of primary recommendations on the date of the Amendment, the State may require WUFSI to pay $500,000 per such secondary recommendation or group of recommendations. There is no monetary penalty associated with secondary recommendations that are classified as such on the date of the Amendment or any new secondary recommendations that the Monitor makes after the date of the Amendment. The Amendment requires WUFSI to continue funding the Monitor’s reasonable expenses in $500,000 increments as requested by the Monitor. The Amendment also requires WUFSI to make a one-time payment of $250,000 , which was paid in March 2014, and thereafter $150,000 per month for five years to fund the activities and expenses of a money transfer transaction data analysis center formed by WUFSI and a Financial Crimes Task Force comprised of federal, state and local law enforcement representatives, including those from the State. In addition, California, Texas, and New Mexico are participating in the money transfer transaction data analysis center. The changes in WUFSI’s AML program required by the Southwest Border Agreement, including the Amendment, and the Monitor’s recommendations have had, and will continue to have, adverse effects on the Company’s business, including additional costs. Additionally, if WUFSI is not able to implement a successful AML compliance program along the U.S. and Mexico border or timely implement the Monitor’s recommendations, each as determined by the Monitor, the State may pursue remedies under the Southwest Border Agreement and Amendment, including assessment of fines and civil and criminal actions. The Company submitted all of the primary recommendations to the Monitor for review prior to an October 31, 2015 deadline and is currently in the process of demonstrating its compliance with the primary recommendations, but is unable to predict whether the Monitor will conclude that WUFSI has implemented an effective AML compliance program and whether the Monitor's primary and secondary recommendations have been successfully implemented. Based on the stage of this matter, the Company cannot reasonably estimate the possible loss or range of loss, if any. Should the State pursue remedies under the Southwest Border Agreement, the Company could face significant fines and actions which could have a material adverse effect on the Company’s business, financial condition, results of operations, and cash flows. United States Department of Justice Investigations On March 20, 2012, the Company was served with a federal grand jury subpoena issued by the United States Attorney's Office for the Central District of California ("USAO-CDCA") seeking documents relating to Shen Zhou International ("US Shen Zhou"), a former Western Union agent located in Monterey Park, California. The principal of US Shen Zhou was indicted in 2010 and in December 2013, pled guilty to one count of structuring international money transfers in violation of United States federal law in U.S. v. Zhi He Wang (SA CR 10-196, C.D. Cal.). Concurrent with the government's service of the subpoena, the government notified the Company that it is a target of an ongoing investigation into structuring and money laundering. Since March 20, 2012, the Company has received additional subpoenas from the USAO-CDCA seeking additional documents relating to US Shen Zhou, materials relating to certain other former and current agents and other materials relating to the Company's AML compliance policies and procedures. The government has interviewed several current and former Western Union employees and has served grand jury subpoenas seeking testimony from several current and former employees. The government's investigation is ongoing and the Company may receive additional requests for information as part of the investigation. The Company has provided and continues to provide information and documents to the government. Due to the investigative stage of the matter and the fact that no criminal charges or civil claims have been brought, the Company is unable to predict the outcome of the government's investigation, or reasonably estimate the possible loss or range of loss, if any, which could be associated with the resolution of any possible charges or claims that may be brought against the Company. Should such charges or claims be brought, the Company could face significant fines, damage awards or regulatory consequences which could have a material adverse effect on the Company's business, financial condition, results of operations, and cash flows. In March 2012, the Company was served with a federal grand jury subpoena issued by the United States Attorney’s Office for the Eastern District of Pennsylvania (“USAO-EDPA”) seeking documents relating to Hong Fai General Contractor Corp. (formerly known as Yong General Construction) (“Hong Fai”), a former Western Union agent located in Philadelphia, Pennsylvania. Since March 2012, the Company has received additional subpoenas from the USAO-EDPA seeking additional documents relating to Hong Fai. The government's investigation is ongoing and the Company may receive additional requests for information as part of the investigation. The Company has provided and continues to provide information and documents to the government. The government has interviewed several current and former Western Union employees. Due to the investigative stage of the matter and the fact that no criminal charges or civil claims have been brought, the Company is unable to predict the outcome of the government's investigation, or reasonably estimate the possible loss or range of loss, if any, which could be associated with the resolution of any possible charges or claims that may be brought against the Company. Should such charges or claims be brought, the Company could face significant fines, damage awards or regulatory consequences which could have a material adverse effect on the Company's business, financial condition, results of operations, and cash flows. On November 25, 2013, the Company was served with a federal grand jury subpoena issued by the United States Attorney’s Office for the Middle District of Pennsylvania (“USAO-MDPA”) seeking documents relating to complaints made to the Company by consumers anywhere in the world relating to fraud-induced money transfers since January 1, 2008. Concurrent with the government's service of the subpoena, the government notified the Company that it is the subject of the investigation. Since November 25, 2013, the Company has received additional subpoenas from the USAO-MDPA seeking documents relating to certain Western Union agents and Western Union’s agent suspension and termination policies. The government has interviewed several current and former employees and has served grand jury subpoenas seeking testimony from several current and former employees. The government has indicated that it believes Western Union failed to timely terminate or suspend certain Western Union agents who allegedly paid or forwarded thousands of fraud-induced transactions sent from the United States to various countries from at least 2008 to 2012. The government's investigation is ongoing and the Company may receive additional requests for information as part of the investigation. The Company has provided and continues to provide information and documents to the government. Due to the investigative stage of the matter and the fact that no criminal charges or civil claims have been brought, the Company is unable to predict the outcome of the government's investigation, or reasonably estimate the possible loss or range of loss, if any, which could be associated with the resolution of any possible charges or claims that may be brought against the Company. Should such charges or claims be brought, the Company could face significant fines, damage awards or regulatory consequences which could have a material adverse effect on the Company's business, financial condition, results of operations, and cash flows. On March 6, 2014, the Company was served with a federal grand jury subpoena issued by the United States Attorney’s Office for the Southern District of Florida (“USAO-SDFL”) seeking a variety of AML compliance materials, including documents relating to the Company’s AML, Bank Secrecy Act (“BSA”), Suspicious Activity Report (“SAR”) and Currency Transaction Report procedures, transaction monitoring protocols, BSA and AML training programs and publications, AML compliance investigation reports, compliance-related agent termination files, SARs, BSA audits, BSA and AML-related management reports and AML compliance staffing levels. The subpoena also calls for Board meeting minutes and organization charts. The period covered by the subpoena is January 1, 2007 to November 27, 2013. The Company has received additional subpoenas from the USAO-SDFL and the Broward County, Florida Sheriff’s Office relating to the investigation, including a federal grand jury subpoena issued by the USAO-SDFL on March 14, 2014, seeking information about 33 agent locations in Costa Rica such as ownership and operating agreements, SARs and AML compliance and BSA filings for the period January 1, 2008 to November 27, 2013. Subsequently, the USAO-SDFL served the Company with seizure warrants requiring the Company to seize all money transfers sent from the United States to two agent locations located in Costa Rica for a 10 -day period beginning in late March 2014. On July 8, 2014, the government served a grand jury subpoena calling for records relating to transactions sent from the United States to Nicaragua and Panama between September 1, 2013 and October 31, 2013. Further, the government recently served Western Union with a subpoena calling for data relating to transactions sent and received by 43 Nicaraguan agents from October 1, 2008 to October 31, 2013 and transactions sent from the United States to the Bahamas, Peru, Dominican Republic, and Haiti from September 1, 2013 to January 2, 2014 and certain documents relating to those agents. The government also advised the Company that it is investigating concerns the Company was aware there were gaming transactions being sent to Panama, Nicaragua, Haiti, Philippines, Vietnam, the Dominican Republic, Peru, and the Bahamas (in addition to Costa Rica) and that the Company failed to take proper steps to stop the activity. The government has also notified the Company that it is a target of the investigation. The government has interviewed several current and former Western Union employees. The government's investigation is ongoing and the Company may receive additional requests for information or seizure warrants as part of the investigation. The Company has provided and continues to provide information and documents to the government. Due to the investigative stage of the matter and the fact that no criminal charges or civil claims have been brought, the Company is unable to predict the outcome of the government's investigation, or reasonably estimate the possible loss or range of loss, if any, which could be associated with the resolution of any possible charges or claims that may be brought against the Company. Should such charges or claims be brought, the Company could face significant fines, damage awards or regulatory consequences which could have a material adverse effect on the Company's business, financial condition, results of operations, and cash flows. Shareholder Action and Other Matters On December 10, 2013, City of Taylor Police and Fire Retirement System filed a purported class action complaint in the United States District Court for the District of Colorado against The Western Union Company, its President and Chief Executive Officer and a former executive officer of the Company, asserting claims under sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (“Exchange Act”) and Securities and Exchange Commission rule 10b-5 against all defendants. On September 26, 2014, the Court appointed SEB Asset Management S.A. and SEB Investment Management AB as lead plaintiffs. On October 27, 2014, lead plaintiffs filed a consolidated amended class action complaint, which asserts the same claims as the original complaint, except that it brings the claims under section 20(a) of the Exchange Act only against the individual defendants. The consolidated amended complaint also adds as a defendant another former executive officer of the Company. The consolidated amended complaint alleges that, during the purported class period, February 7, 2012 through October 30, 2012, defendants made false or misleading statements or failed to disclose adverse material facts known to them, including those regarding: (1) the competitive advantage the Company derived from its compliance program; (2) the Company’s ability to increase market share, make limited price adjustments and withstand competitive pressures; (3) the effect of compliance measures under the Southwest Border Agreement on agent retention and business in Mexico; and (4) the Company’s progress in implementing an anti-money laundering program for the Southwest Border Area. On December 11, 2014, the defendants filed a motion to dismiss the consolidated amended complaint. The Court referred the motion to a Magistrate Judge, who, on April 14, 2015, issued a report and recommendation, which recommended that the defendants’ motion to dismiss be granted and that the consolidated amended complaint be dismissed in full. On April 28, 2015, plaintiffs filed objections to the report and recommendation. On September 29, 2015, the Court (a) overruled in part and sustained in part plaintiffs’ objections to the report and recommendation; (b) adopted in part the recommendation; (c) granted in part and denied in part defendants’ motion to dismiss the consolidated amended complaint; and (d) dismissed the claims against one of the individual defendants and denied the motion as to the remaining defendants. In particular, the Court denied the motion to dismiss as to certain statements made by the Company’s President and Chief Executive Officer and a former executive officer during an investor conference call on July 24, 2012, related to category (3) above concerning the effect of compliance measures under the Southwest Border Agreement on agent retention and business in Mexico. On November 3, 2015, defendants filed an answer to the consolidated amended complaint. On February 5, 2016, plaintiffs notified the Court that a witness on whom they had relied in bringing their claims did not have firsthand knowledge of events occurring at Western Union during calendar year 2012, and that without the witness’ support of their claims the consolidated amended complaint would not have survived the defendants’ motion to dismiss. The same day, plaintiffs voluntarily dismissed the consolidated amended complaint with prejudice. The Company and one of its subsidiaries are defendants in two purported class action lawsuits: James P. Tennille v. The Western Union Company and Robert P. Smet v. The Western Union Company, both of which are pending in the United States District Court for the District of Colorado. The original complaints asserted claims for violation of various consumer protection laws, unjust enrichment, conversion and declaratory relief, based on allegations that the Company waits too long to inform consumers if their money transfers are not redeemed by the recipients and that the Company uses the unredeemed funds to generate income until the funds are escheated to state governments. The Tennille complaint was served on the Company on April 27, 2009. The Smet complaint was served on the Company on April 6, 2010. On September 21, 2009, the Court granted the Company's motion to dismiss the Tennille complaint and gave the plaintiff leave to file an amended complaint. On October 21, 2009, Tennille filed an amended complaint. The Company moved to dismiss the Tennille amended complaint and the Smet complaint. On November 8, 2010, the Court denied the motion to dismiss as to the plaintiffs' unjust enrichment and conversion claims. On February 4, 2011, the Court dismissed the plaintiffs' consumer protection claims. On March 11, 2011, the plaintiffs filed an amended complaint that adds a claim for breach of fiduciary duty, various elements to its declaratory relief claim and WUFSI as a defendant. On April 25, 2011, the Company and WUFSI filed a motion to dismiss the breach of fiduciary duty and declaratory relief claims. WUFSI also moved to compel arbitration of the plaintiffs' claims and to stay the action pending arbitration. On November 21, 2011, the Court denied the motion to compel arbitration and the stay request. Both companies appealed the decision. On January 24, 2012, the United States Court of Appeals for the Tenth Circuit granted the companies' request to stay the District Court proceedings pending their appeal. During the fourth quarter of 2012, the parties executed a settlement agreement, which the Court preliminarily approved on January 3, 2013. On June 25, 2013, the Court entered an order certifying the class and granting final approval to the settlement. Under the approved settlement, a substantial amount of the settlement proceeds, as well as all of the class counsel’s fees, administrative fees and other expenses, would be paid from the class members' unclaimed money transfer funds, which are included within "Settlement obligations" in the Company's Consolidated Balance Sheets. These fees and other expenses are currently estimated to be approximately $50 million . During the final approval hearing, the Court overruled objections to the settlement that had been filed by several class members. In July 2013, two of those class members filed notices of appeal. On May 1, 2015, the United States Court of Appeals for the Tenth Circuit affirmed the District Court’s decision to overrule the objections filed by the two class members who appealed. On January 11, 2016, the United States Supreme Court denied petitions for certiorari that were filed by the two class members who appealed. On February 1, 2016, pursuant to the settlement agreement and the Court's June 25, 2013 final approval order, Western Union deposited the class members' unclaimed money transfer funds into a class settlement fund, from which class member claims, administrative fees and class counsel’s fees, as well as other expenses will be paid. On November 6, 2013, the Attorney General of California notified Western Union of the California Controller’s position that Western Union’s deposit of the unclaimed money transfer funds into the class settlement fund pursuant to the settlement “will not satisfy Western Union’s obligations to report and remit funds” under California’s unclaimed property law, and that “Western Union will remain liable to the State of California” for the funds that would have escheated to California in the absence of the settlement. The State of Pennsylvania and District of Columbia have previously expressed similar views. Other states have also recently expressed concerns about the settlement and many have not yet expressed an opinion. Since some states and jurisdictions believe that the Company must escheat its full share of the settlement fund and that the deductions for class counsel's fees, administrative costs, and other expenses that are required under the settlement agreement are not permitted, there is a reasonable possibility a loss could result up to approximately the amount of those fees and other expenses. However, given the number of jurisdictions involved and the fact that no actions have been brought, the Company is unable to provide a more precise estimate of the range of possible loss. The Company has had discussions with the United States Federal Trade Commission (the "FTC") regarding the Company's consumer protection and anti-fraud programs. On December 12, 2012, the Company received a civil investigative demand from the FTC requesting that the Company produce (i) all documents relating to communications with the Monitor appointed pursuant to the Southwest Border Agreement, including information the Company provided to the Monitor and any reports prepared by the Monitor; and (ii) all documents relating to complaints made to the Company by consumers anywhere in the world relating to fraud-induced money transfers since January 1, 2011. On April 15, 2013, the FTC filed a petition in the United States District Court for the Southern District of New York requesting an order to compel production of the requested documents. On June 6, 2013, the Court granted in part and denied in part the FTC's request. On August 14, 2013, the FTC filed a notice of appeal. On August 27, 2013, Western Union filed a notice of cross-appeal. On February 21, 2014, the Company received another civil investigative demand from the FTC requesting the production of all documents relating to complaints made to the Company by or on behalf of consumers relating to fraud-induced money transfers that were sent from or received in the United States since January 1, 2004, except for documents that were already produced to the FTC in response to the first civil investigative demand. On October 7, 2014, the United States Court of Appeals for the Second Circuit entered a summary order reversing in part and vacating and remanding in part the June 6, 2013 order entered by the United States District Court for the Southern District of New York. On October 22, 2014, the Company received another civil investigative demand issued by the FTC requesting documents and information since January 1, 2004 relating to the Company’s consumer fraud program, its policies and procedures governing agent termination, suspension, probation and reactivation, its efforts to comply with its 2005 agreement with 47 states and the District of Columbia regarding consumer fraud prevention, and complaints made to the Company by or on behalf of consumers concerning fraud-induced money transfers that were sent to or from the United States, excluding complaint-related documents that were produced to the FTC in response to the earlier civil investigative demands. The civil investigative demand also seeks various documents concerning approximately 720 agents, including documents relating to the transactions they sent and paid and the Company’s investigations of and communications with them. On July 31, 2015, the Company received another civil investigative demand requesting documents and information relating to the total number of agent and subagent locations in 13 countries annually since 2010, the average and median dollar values for money transfers sent anywhere in the world annually since 2010, copies of the Company’s anti-fraud programs, know your agent policy, know your customer policy, representative agent contracts, transaction data, background investigation documents and fraud complaints associated with four agents in Greece, Peru and Mexico and consumer fraud reports not already produced to the FTC. The Company has responded to each of the civil investigative demands it has received from the FTC. The Company may receive additional civil investigative demands from the FTC, and discussions between the Company and the FTC are ongoing. Due to the investigative stage of the matter and the fact that no claims have been brought, the Company is unable to predict the outcome of the government’s investigation, or reasonably estimate the possible loss or range of loss, if any, which could be associated with the resolution of any possible claims that may be brought against the Company. In August 2013, the Consumer Financial Protection Bureau (the "CFPB") served Paymap, Inc. ("Paymap"), a subsidiary of the Company which operates solely in the United States, with a civil investigative demand requesting information and documents about Paymap’s Equity Accelerator service, which is designed to help consumers pay off their mortgages more quickly. In August 2014, the CFPB advised the Company of its view that certain aspects of Paymap’s marketing violated the Consumer Financial Protection Act’s prohibition against unfair, deceptive and abusive acts and practices. In July 2015, Paymap agreed to resolve the matter without admitting or denying the CFPB's allegations ("Paymap Settlement Agreement"), and also agreed to pay approximately $33.4 million in restitution and a $5.0 million civil monetary penalty. The Company paid $5.0 million during the third quarter of 2015 and has segregated funds that are included in "Other assets" in the Company's Consolidated Balance Sheets which will be used to pay the remaining $33.4 million . As this matter has been settled, the Company believes that the potential for additional loss in excess of amounts already accrued is remote. On March 12, 2014, Jason Douglas filed a purported class action complaint in the United States District Court for the Northern District of Illinois asserting a claim under the Telephone Consumer Protection Act, 47 U.S.C. § 227, et seq., based on allegations that since 2009, the Company has sent text messages to class members’ wireless telephones without their consent. During the first quarter of 2015, the Company's insurance carrier and the plaintiff reached an agreement to create an $8.5 million settlement fund that will be used to pay all class member claims, class counsel’s fees and the costs of administering the settlement. The agreement has been signed by the parties and, on November 10, 2015, the Court granted preliminary approval to the settlement. The Company accrued an amount equal to the retention under its insurance policy in previous quarters and believes that any amounts in excess of this accrual will be covered by the insurer. However, if the Company's insurer is unable to or refuses to satisfy its obligations under the policy or the parties are unable to reach a definitive agreement or otherwise agree on a resolution, the Company's financial condition, results of operations, and cash flows could be adversely impacted. As the parties have reached an agreement in this matter, the Company believes that the potential for additional loss in excess of amounts already accrued is remote. On February 10, 2015, Caryn Pincus filed a purported class action lawsuit in the United States District Court for the Southern District of Florida against Speedpay, Inc. (“Speedpay”), a subsidiary of the Company, asserting claims based on allegations that Speedpay imposed an unlawful surcharge on

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Investment Securities Investment securities included in "Settlement assets" in the Consolidated Balance Sheets consist primarily of highly-rated state and municipal debt securities, including fixed rate term notes and variable rate demand notes. Variable rate demand note securities can be put (sold at par) typically on a daily basis with settlement periods ranging from the same day to one week, but have varying maturities through 2049 . Generally, these securities are used by the Company for short-term liquidity needs and are held for short periods of time, typically less than 30 days . The Company is required to hold highly-rated, investment grade securities and such investments are restricted to satisfy outstanding settlement obligations in accordance with applicable state and foreign country requirements. The substantial majority of the Company's investment securities are classified as available-for-sale and recorded at fair value. Investment securities are exposed to market risk due to changes in interest rates and credit risk. Western Union regularly monitors credit risk and attempts to mitigate its exposure by investing in highly-rated securities and through investment diversification. Unrealized gains and losses on available-for-sale securities are excluded from earnings and presented as a component of accumulated other comprehensive income or loss, net of related deferred taxes. Proceeds from the sale and maturity of available-for-sale securities during the years ended December 31, 2015 , 2014 and 2013 were $8.7 billion , $17.7 billion and $19.0 billion , respectively. Gains and losses on investments are calculated using the specific-identification method and are recognized during the period in which the investment is sold or when an investment experiences an other-than-temporary decline in value. Factors that could indicate an impairment exists include, but are not limited to: earnings performance, changes in credit rating or adverse changes in the regulatory or economic environment of the asset. If potential impairment exists, the Company assesses whether it has the intent to sell the debt security, more likely than not will be required to sell the debt security before its anticipated recovery or expects that some of the contractual cash flows will not be received. The Company had no material other-than-temporary impairments during the periods presented. The components of investment securities are as follows (in millions): December 31, 2015 Amortized Cost Fair Value Gross Unrealized Gains Gross Unrealized Losses Net Unrealized Gains/ (Losses) Settlement assets: Available-for-sale securities: State and municipal debt securities (a) $ 1,040.3 $ 1,052.5 $ 14.2 $ (2.0 ) $ 12.2 State and municipal variable rate demand notes 42.9 42.9 — — — Corporate and other debt securities 67.3 67.2 — (0.1 ) (0.1 ) 1,150.5 1,162.6 14.2 (2.1 ) 12.1 Other assets: Held-to-maturity securities: Foreign corporate debt securities 9.3 9.3 — — — $ 1,159.8 $ 1,171.9 $ 14.2 $ (2.1 ) $ 12.1 December 31, 2014 Amortized Cost Fair Value Gross Unrealized Gains Gross Unrealized Losses Net Unrealized Gains/ (Losses) Settlement assets: State and municipal debt securities (a) $ 1,024.2 $ 1,038.1 $ 15.1 $ (1.2 ) $ 13.9 State and municipal variable rate demand notes 316.8 316.8 — — — Corporate and other debt securities 70.5 70.5 0.1 (0.1 ) — Short-term state and municipal bond mutual fund 47.1 47.1 — — — $ 1,458.6 $ 1,472.5 $ 15.2 $ (1.3 ) $ 13.9 ____________ (a) The majority of these securities are fixed rate instruments. There were no investments with a single issuer or individual securities representing greater than 10% of total investment securities as of December 31, 2015 and 2014 . The following summarizes the contractual maturities of settlement-related debt securities as of December 31, 2015 (in millions): Amortized Cost Fair Value Due within 1 year $ 195.5 $ 196.0 Due after 1 year through 5 years 499.9 500.9 Due after 5 years through 10 years 394.9 405.5 Due after 10 years 60.2 60.2 $ 1,150.5 $ 1,162.6 Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay the obligations or the Company may have the right to put the obligation prior to its contractual maturity, as with variable rate demand notes. Variable rate demand notes, having a fair value of $2.9 million and $40.0 million are included in the "Due after 1 year through 5 years" and "Due after 10 years" categories, respectively, in the table above. The majority of the held-to-maturity foreign corporate debt securities are due within 1 year.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value, as defined by the relevant accounting standards, represents the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. For additional information on how the Company measures fair value, refer to Note 2. The following tables reflect assets and liabilities that were measured at fair value on a recurring basis (in millions): Fair Value Measurement Using Assets/ Liabilities at Fair Value December 31, 2015 Level 1 Level 2 Level 3 Assets: Settlement assets: State and municipal debt securities $ — $ 1,052.5 $ — $ 1,052.5 State and municipal variable rate demand notes — 42.9 — 42.9 Corporate and other debt securities — 67.2 — 67.2 Other assets: Derivatives — 396.3 — 396.3 Foreign corporate debt securities — 9.3 — 9.3 Total assets $ — $ 1,568.2 $ — $ 1,568.2 Liabilities: Derivatives $ — $ 283.7 $ — $ 283.7 Total liabilities $ — $ 283.7 $ — $ 283.7 Fair Value Measurement Using Assets/ Liabilities at Fair Value December 31, 2014 Level 1 Level 2 Level 3 Assets: Settlement assets: State and municipal debt securities $ — $ 1,038.1 $ — $ 1,038.1 State and municipal variable rate demand notes — 316.8 — 316.8 Corporate and other debt securities — 70.5 — 70.5 Short-term state and municipal bond mutual fund 47.1 — — 47.1 Other assets: Derivatives — 423.0 — 423.0 Total assets $ 47.1 $ 1,848.4 $ — $ 1,895.5 Liabilities: Derivatives $ — $ 317.1 $ — $ 317.1 Total liabilities $ — $ 317.1 $ — $ 317.1 No non-recurring fair value adjustments were recorded during the years ended December 31, 2015 and 2014 . Other Fair Value Measurements The carrying amounts for many of the Company's financial instruments, including cash and cash equivalents, settlement cash and cash equivalents, and settlement receivables and settlement obligations approximate fair value due to their short maturities. The Company's borrowings are classified as Level 2 of the valuation hierarchy, and the aggregate fair value of these borrowings was based on quotes from multiple banks and excluded the impact of related interest rate swaps. Fixed rate notes are carried in the Company's Consolidated Balance Sheets at their original issuance values as adjusted over time to accrete that value to par, except for portions of notes hedged by these interest rate swaps, as disclosed in Note 14. As of December 31, 2015 , the carrying value and fair value of the Company's borrowings was $3,225.6 million and $3,279.6 million , respectively (see Note 15). As of December 31, 2014 , the carrying value and fair value of the Company's borrowings was $3,720.4 million and $3,890.5 million , respectively. The Company's foreign corporate debt securities are classified as held-to-maturity securities within Level 2 of the valuation hierarchy and are recorded at amortized cost in "Other Assets" in the Company's Consolidated Balance Sheets. The fair value of the assets in the Trust, which holds the assets for the Company's defined benefit plan, is disclosed in Note 11.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The components of pre-tax income, generally based on the jurisdiction of the legal entity, were as follows (in millions): Year Ended December 31, 2015 2014 2013 Domestic $ (27.0 ) $ 34.7 $ (28.4 ) Foreign 968.8 933.5 955.3 $ 941.8 $ 968.2 $ 926.9 For the years ended December 31, 2015 , 2014 and 2013 , 103% , 96% and 103% of the Company's pre-tax income was derived from foreign sources, respectively. The provision for income taxes was as follows (in millions): Year Ended December 31, 2015 2014 2013 Federal $ 33.2 $ 57.0 $ 88.3 State and local (1.0 ) 4.9 (3.7 ) Foreign 71.8 53.9 43.9 $ 104.0 $ 115.8 $ 128.5 Domestic taxes have been incurred on certain pre-tax income amounts that were generated by the Company's foreign operations. Accordingly, the percentage obtained by dividing the total federal, state and local tax provision by the domestic pre-tax income, all as shown in the preceding tables, may be higher than the statutory tax rates in the United States. The Company's effective tax rates differed from statutory rates as follows: Year Ended December 31, 2015 2014 2013 Federal statutory rate 35.0 % 35.0 % 35.0 % State income taxes, net of federal income tax benefits 0.4 % 0.6 % 0.7 % Foreign rate differential, net of U.S. tax paid on foreign earnings (3.4%, 4.3% and 9.2%, respectively) (24.6 )% (24.0 )% (22.9 )% Other 0.2 % 0.4 % 1.1 % Effective tax rate 11.0 % 12.0 % 13.9 % The decrease in the Company's effective tax rate for the year ended December 31, 2015 compared to 2014 is primarily due to various tax planning benefits, some of which are non-recurring, partially offset by changes in the composition of foreign earnings between higher taxed and lower taxed and the combined effects of various discrete items. The decrease in the Company's effective tax rate for the year ended December 31, 2014 compared to 2013 is primarily due to the combined effect of various discrete items, including those related to foreign currency fluctuations on certain income tax attributes, and changes in tax contingency reserves, partially offset by changes in the composition of earnings between foreign and domestic. The Company continues to benefit from a significant proportion of its profits being foreign-derived and generally taxed at lower rates than its combined federal and state tax rates in the United States. Certain portions of the Company's foreign source income are subject to United States federal and state income tax as earned due to the nature of the income, and dividend repatriations of the Company's foreign source income are generally subject to United States federal and state income tax. The Company's provision for income taxes consisted of the following components (in millions): Year Ended December 31, 2015 2014 2013 Current: Federal $ 59.6 $ 76.1 $ 86.1 State and local 5.4 4.7 8.1 Foreign 78.9 61.8 73.6 Total current taxes 143.9 142.6 167.8 Deferred: Federal (26.4 ) (19.1 ) 2.2 State and local (6.4 ) 0.2 (11.8 ) Foreign (7.1 ) (7.9 ) (29.7 ) Total deferred taxes (39.9 ) (26.8 ) (39.3 ) $ 104.0 $ 115.8 $ 128.5 Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the book and tax bases of the Company's assets and liabilities. The following table outlines the principal components of deferred tax items (in millions): December 31, 2015 2014 Deferred tax assets related to: Reserves, accrued expenses and employee-related items $ 87.1 $ 81.8 Tax attribute carryovers 60.2 41.0 Pension obligations 26.5 26.7 Intangibles, property and equipment 7.9 12.1 Other 10.2 13.6 Valuation allowance (33.2 ) (46.6 ) Total deferred tax assets 158.7 128.6 Deferred tax liabilities related to: Intangibles, property and equipment 410.9 428.1 Other 12.5 5.5 Total deferred tax liabilities 423.4 433.6 Net deferred tax liability (a) $ 264.7 $ 305.0 ____________ (a) As of December 31, 2015 , deferred tax assets that cannot be fully offset by deferred tax liabilities in the respective tax jurisdictions are reflected in "Other assets" in the Consolidated Balance Sheets. The valuation allowances are primarily the result of uncertainties regarding the Company's ability to recognize tax benefits associated with certain U.S. foreign tax credit carryforwards, certain foreign net operating losses, and certain foreign undistributed earnings. Such uncertainties include generating sufficient income, generating sufficient U.S. foreign tax credit limitation related to passive income, and demonstrating the ability to distribute certain foreign earnings. Changes in circumstances, or the identification and implementation of relevant tax planning strategies, could make it foreseeable that the Company will recover these deferred tax assets in the future, which could lead to a reversal of these valuation allowances and a reduction in income tax expense. Uncertain Tax Positions The Company has established contingency reserves for a variety of material, known tax exposures. As of December 31, 2015 , the total amount of tax contingency reserves was $113.1 million , including accrued interest and penalties, net of related items. The Company's tax reserves reflect management's judgment as to the resolution of the issues involved if subject to judicial review or other settlement. While the Company believes its reserves are adequate to cover reasonably expected tax risks, there can be no assurance that, in all instances, an issue raised by a tax authority will be resolved at a financial cost that does not exceed its related reserve. With respect to these reserves, the Company's income tax expense would include (i) any changes in tax reserves arising from material changes during the period in the facts and circumstances (i.e., new information) surrounding a tax issue and (ii) any difference from the Company's tax position as recorded in the financial statements and the final resolution of a tax issue during the period. Such resolution could materially increase or decrease income tax expense in the Company's consolidated financial statements in future periods and could impact operating cash flows. Unrecognized tax benefits represent the aggregate tax effect of differences between tax return positions and the amounts otherwise recognized in the Company's consolidated financial statements, and are reflected in "Income taxes payable" in the Consolidated Balance Sheets. A reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding interest and penalties, is as follows (in millions): 2015 2014 Balance as of January 1, $ 93.4 $ 117.5 Increases - positions taken in current period (a) 17.1 12.2 Increases - positions taken in prior periods (b) 7.7 5.7 Decreases - positions taken in prior periods (b) (5.4 ) (23.9 ) Decreases - settlements with taxing authorities — (8.1 ) Decreases - lapse of applicable statute of limitations (5.6 ) (7.2 ) Decreases - effects of foreign currency exchange rates (1.6 ) (2.8 ) Balance as of December 31, $ 105.6 $ 93.4 ____________ (a) Includes recurring accruals for issues which initially arose in previous periods. (b) Changes to positions taken in prior periods relate to changes in estimates used to calculate prior period unrecognized tax benefits. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $96.8 million and $82.4 million as of December 31, 2015 and 2014 , respectively, excluding interest and penalties. The Company recognizes interest and penalties with respect to unrecognized tax benefits in "Provision for income taxes" in its Consolidated Statements of Income, and records the associated liability in "Income taxes payable" in its Consolidated Balance Sheets. The Company recognized $1.9 million , $1.5 million and $(1.8) million in interest and penalties during the years ended December 31, 2015 , 2014 and 2013 , respectively. The Company has accrued $17.0 million and $15.1 million for the payment of interest and penalties as of December 31, 2015 and 2014 , respectively. The unrecognized tax benefits accrual as of December 31, 2015 consists of federal, state and foreign tax matters. It is reasonably possible that the Company's total unrecognized tax benefits will decrease by approximately $26 million during the next 12 months in connection with various matters which may be resolved. The Company and its subsidiaries file tax returns for the United States, for multiple states and localities, and for various non-United States jurisdictions, and the Company has identified the United States as its major tax jurisdiction, as the income tax imposed by any one foreign country is not material to the Company. The United States federal income tax returns of First Data, which include the Company, are eligible to be examined for 2005 and 2006. The Company's United States federal income tax returns since the Spin-off are also eligible to be examined. The United States Internal Revenue Service ("IRS") completed its examination of the United States federal consolidated income tax returns of First Data for 2003 and 2004, which included the Company, and issued a Notice of Deficiency in December 2008. In December 2011, the Company reached an agreement with the IRS resolving substantially all of the issues related to the Company's restructuring of its international operations in 2003 ("IRS Agreement"). As a result of the IRS Agreement, the Company expects to make cash payments of approximately $190 million , plus additional accrued interest, of which $94.1 million has been paid as of December 31, 2015 . A substantial majority of these payments were made in the year ended December 31, 2012. The Company expects to pay the remaining amount in 2016 and beyond. The IRS completed its examination of the United States federal consolidated income tax returns of First Data, which include the Company's 2005 and pre-Spin-off 2006 taxable periods and issued its report on October 31, 2012 ("FDC 30-Day Letter"). Furthermore, the IRS completed its examination of the Company's United States federal consolidated income tax returns for the 2006 post-Spin-off period through 2009 and issued its report also on October 31, 2012 ("WU 30-Day Letter"). Both the FDC 30-Day Letter and the WU 30-Day Letter propose tax adjustments affecting the Company, some of which are agreed and some of which are unagreed. Both First Data and the Company filed their respective protests with the IRS Appeals Division on November 28, 2012 related to the unagreed proposed adjustments. Discussions with the IRS concerning these adjustments are ongoing. The Company believes its reserves are adequate with respect to both the agreed and unagreed adjustments. As of December 31, 2015 , no provision has been made for United States federal and state income taxes on certain of the Company's outside tax basis differences, which primarily relate to accumulated foreign earnings of approximately $6.1 billion , which have been reinvested and are expected to continue to be reinvested outside the United States indefinitely. Over the last several years, such earnings have been used to pay for the Company's international acquisitions and operations and provide initial Company funding of global principal payouts for Consumer-to-Consumer and Business Solutions transactions. Upon distribution of those earnings to the United States in the form of actual or constructive dividends, the Company would be subject to United States income taxes (subject to an adjustment for foreign tax credits), state income taxes and possible withholding taxes payable to various foreign countries. Such taxes could be significant. Determination of this amount of unrecognized United States deferred tax liability is not practicable because of the complexities associated with its hypothetical calculation. Tax Allocation Agreement with First Data The Company and First Data each are liable for taxes imposed on their respective businesses both prior to and after the Spin-off. If such taxes have not been appropriately apportioned between First Data and the Company, subsequent adjustments may occur that may impact the Company's financial condition or results of operations. Also under the tax allocation agreement, with respect to taxes and other liabilities that result from a final determination that is inconsistent with the anticipated tax consequences of the Spin-off (as set forth in the private letter ruling and relevant tax opinion) ("Spin-off Related Taxes"), the Company will be liable to First Data for any such Spin-off Related Taxes attributable solely to actions taken by or with respect to the Company. In addition, the Company will also be liable for half of any Spin-off Related Taxes (i) that would not have been imposed but for the existence of both an action by the Company and an action by First Data or (ii) where the Company and First Data each take actions that, standing alone, would have resulted in the imposition of such Spin-off Related Taxes. The Company may be similarly liable if it breaches certain representations or covenants set forth in the tax allocation agreement. If the Company is required to indemnify First Data for taxes incurred as a result of the Spin-off being taxable to First Data, it likely would have a material adverse effect on the Company's business, financial condition and results of operations. First Data generally will be liable for all Spin-off Related Taxes, other than those described above.

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	Employee Benefit Plans Defined Contribution Plans The Company administers several defined contribution plans in various countries globally, including The Western Union Company Incentive Savings Plan (the "401(k)"), which covers eligible employees on the United States payroll. Such plans have vesting and employer contribution provisions that vary by country. In addition, the Company sponsors a non-qualified deferred compensation plan for a select group of highly compensated United States employees. The plan provides tax-deferred contributions and the restoration of Company matching contributions otherwise limited under the 401(k). The aggregate amount charged to expense in connection with all of the above plans was $18.0 million , $17.4 million and $16.9 million during the years ended December 31, 2015 , 2014 and 2013 , respectively. Defined Benefit Plan The Company has a frozen defined benefit pension plan (the "Plan") and recognizes its funded status, measured as the difference between the fair value of the plan assets and the projected benefit obligation, in "Other liabilities" in the Consolidated Balance Sheets. Plan assets, which are managed in a third-party trust, primarily consist of a diversified blend of approximately 60% debt securities, 20% equity investments, and 20% alternative investments (e.g., hedge funds, royalty rights and private equity funds) and had a total fair value of $276.7 million and $302.9 million as of December 31, 2015 and 2014 , respectively. The significant majority of plan assets fall within either Level 1 or Level 2 of the fair value hierarchy. The benefit obligation associated with the Plan will vary over time only as a result of changes in market interest rates, the life expectancy of the plan participants, and benefit payments, since the accrual of benefits was suspended when the Plan was frozen in 1988. The benefit obligation was $346.0 million and $377.8 million and the discount rate assumption used in the measurement of this obligation was 3.52% and 3.27% as of December 31, 2015 and 2014 , respectively. The Company’s unfunded pension obligation was $69.3 million and $74.9 million as of December 31, 2015 and 2014 , respectively. The net periodic benefit cost associated with the Plan was $2.8 million for the year ended December 31, 2015 and $3.8 million for both of the years ended December 31, 2014 and 2013 . The expected long-term return on plan assets assumption is 7.00% for 2016. The Company made contributions of $6.7 million and $13.2 million to the Plan in the years ended December 31, 2015 and 2014 , respectively. No funding to the Plan will be required for 2016 . The estimated undiscounted future benefit payments are expected to be $35.0 million in 2016, $33.4 million in 2017, $31.9 million in 2018, $30.4 million in 2019, $28.8 million in 2020 and $120.4 million in 2021 through 2025.

Equity [Abstract]
Stockholders' Equity	Stockholders' Equity Accumulated other comprehensive loss Accumulated other comprehensive loss includes all changes in equity during a period that have yet to be recognized in income, except those resulting from transactions with shareholders. The major components include unrealized gains and losses on investment securities, unrealized gains and losses from cash flow hedging activities, foreign currency translation adjustments and defined benefit pension plan adjustments. Unrealized gains and losses on investment securities that are available for sale, primarily state and municipal debt securities, are included in "Accumulated other comprehensive loss" until the investment is either sold or deemed other-than-temporarily impaired. See Note 7 for further discussion. The effective portion of the change in fair value of derivatives that qualify as cash flow hedges are recorded in "Accumulated other comprehensive loss." Generally, amounts are recognized in income when the related forecasted transaction affects earnings. See Note 14 for further discussion. The assets and liabilities of foreign subsidiaries whose functional currency is not the United States dollar are translated using the appropriate exchange rate as of the end of the year. Foreign currency translation adjustments represent unrealized gains and losses on assets and liabilities arising from the difference in the foreign country currency compared to the United States dollar. These gains and losses are accumulated in other comprehensive income. When a foreign subsidiary is substantially liquidated, the cumulative translation gain or loss is removed from "Accumulated other comprehensive loss" and is recognized as a component of the gain or loss on the sale of the subsidiary. The defined benefit pension plan adjustment is recognized for the difference between estimated assumptions (e.g., asset returns, discount rates, mortality) and actual results. The amount in "Accumulated other comprehensive loss" is amortized to income over the remaining life expectancy of the plan participants. Details of the pension plan's assets and obligations are explained further in Note 11. The following table summarizes the components of accumulated other comprehensive loss, net of tax (in millions). All amounts reclassified from accumulated other comprehensive loss affect the line items as indicated below within the Consolidated Statements of Income.

Dividends per share declared quarterly by the Company's Board of Directors during the years ended 2015, 2014 and 2013 were as follows: Year Q1 Q2 Q3 Q4 2015 $ 0.155 $ 0.155 $ 0.155 $ 0.155 2014 $ 0.125 $ 0.125 $ 0.125 $ 0.125 2013 $ 0.125 $ 0.125 $ 0.125 $ 0.125 On February 9, 2016 , the Company's Board of Directors declared a quarterly cash dividend of $0.16 per common share payable on March 31, 2016 . Share Repurchases During the years ended December 31, 2015 , 2014 and 2013 , 25.1 million , 29.3 million and 25.7 million shares, respectively, have been repurchased for $500.0 million , $488.1 million and $393.6 million , respectively, excluding commissions, at an average cost of $19.96 , $16.63 and $15.29 per share, respectively. These amounts represent shares authorized by the Board of Directors for repurchase under the publicly announced authorizations. As of December 31, 2015 , $711.9 million remained available under the share repurchase authorization approved by the Company's Board of Directors through December 31, 2017. The amounts included in the "Common stock repurchased" line in the Company's Consolidated Statements of Cash Flows represent both shares authorized by the Board of Directors for repurchase under the publicly announced authorization, described earlier, as well as shares withheld from employees to cover tax withholding obligations on restricted stock units that have vested.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives The Company is exposed to foreign currency exchange risk resulting from fluctuations in exchange rates, primarily the euro, and to a lesser degree the British pound, Canadian dollar, Australian dollar, Swiss franc, and other currencies, related to forecasted money transfer revenues and on money transfer settlement assets and obligations as well as on certain foreign currency denominated cash and other asset and liability positions. The Company is also exposed to risk from derivative contracts written to its customers arising from its cross-currency Business Solutions payments operations. Additionally, the Company is exposed to interest rate risk related to changes in market rates both prior to and subsequent to the issuance of debt. The Company uses derivatives to (a) minimize its exposures related to changes in foreign currency exchange rates and interest rates and (b) facilitate cross-currency Business Solutions payments by writing derivatives to customers. The Company executes derivatives with established financial institutions, with the substantial majority of these financial institutions having credit ratings of "A-" or better from a major credit rating agency. The Company also writes Business Solutions derivatives mostly with small and medium size enterprises. The primary credit risk inherent in derivative agreements represents the possibility that a loss may occur from the nonperformance of a counterparty to the agreements. The Company performs a review of the credit risk of these counterparties at the inception of the contract and on an ongoing basis. The Company also monitors the concentration of its contracts with any individual counterparty. The Company anticipates that the counterparties will be able to fully satisfy their obligations under the agreements, but takes action when doubt arises about the counterparties' ability to perform. These actions may include requiring Business Solutions customers to post or increase collateral, and for all counterparties, the possible termination of the related contracts. The Company's hedged foreign currency exposures are in liquid currencies; consequently, there is minimal risk that appropriate derivatives to maintain the hedging program would not be available in the future. Foreign Currency — Consumer-to-Consumer The Company's policy is to use longer-term foreign currency forward contracts, with maturities of up to 36 months at inception and a targeted weighted-average maturity of approximately one year, to help mitigate some of the risk that changes in foreign currency exchange rates compared to the United States dollar could have on forecasted revenues denominated in other currencies related to its business. As of December 31, 2015 , the Company's longer-term foreign currency forward contracts had maturities of a maximum of 24 months with a weighted-average maturity of approximately one year. These contracts are accounted for as cash flow hedges of forecasted revenue, with effectiveness assessed based on changes in the spot rate of the affected currencies during the period of designation. Accordingly, all changes in the fair value of the hedges not considered effective or portions of the hedge that are excluded from the measure of effectiveness are recognized immediately in "Derivative gains/(losses), net" within the Company's Consolidated Statements of Income. The Company also uses short duration foreign currency forward contracts, generally with maturities from a few days up to one month, to offset foreign exchange rate fluctuations on settlement assets and obligations between initiation and settlement. In addition, forward contracts, typically with maturities of less than one year at inception, are utilized to offset foreign exchange rate fluctuations on certain foreign currency denominated cash and other asset and liability positions. None of these contracts are designated as accounting hedges. The aggregate equivalent United States dollar notional amounts of foreign currency forward contracts as of December 31, 2015 were as follows (in millions): Contracts designated as hedges: Euro $ 357.5 Canadian dollar 105.8 British pound 92.5 Australian dollar 46.6 Swiss franc 41.9 Other 84.1 Contracts not designated as hedges: Euro $ 284.6 British pound 149.3 Canadian dollar 113.7 Australian dollar 49.5 Indian rupee 30.2 Swiss franc 27.3 Other (a) 162.2 ____________________ (a) Comprised of exposures to 20 different currencies. None of these individual currency exposures is greater than $25 million . Foreign Currency — Business Solutions The Company writes derivatives, primarily foreign currency forward contracts and option contracts, mostly with small and medium size enterprises and derives a currency spread from this activity as part of its Business Solutions operations. The Company aggregates its Business Solutions payments foreign currency exposures arising from customer contracts, including the derivative contracts described above, and hedges the resulting net currency risks by entering into offsetting contracts with established financial institution counterparties (economic hedge contracts). The derivatives written are part of the broader portfolio of foreign currency positions arising from the Company's cross-currency payments operations, which primarily include spot exchanges of currency in addition to forwards and options. The resulting foreign exchange revenues from the total portfolio of positions comprise Business Solutions foreign exchange revenues. None of the derivative contracts used in Business Solutions operations are designated as accounting hedges. The duration of these derivative contracts at inception is generally less than one year. The aggregate equivalent United States dollar notional amount of foreign currency derivative customer contracts held by the Company in its Business Solutions operations as of December 31, 2015 was approximately $5.5 billion . The significant majority of customer contracts are written in major currencies such as the Australian dollar, British pound, Canadian dollar, and euro. Interest Rate Hedging — Corporate The Company utilizes interest rate swaps to effectively change the interest rate payments on a portion of its notes from fixed-rate payments to short-term LIBOR-based variable rate payments in order to manage its overall exposure to interest rates. The Company designates these derivatives as fair value hedges. The change in fair value of the interest rate swaps is offset by a change in the carrying value of the debt being hedged within "Borrowings" in the Consolidated Balance Sheets and "Interest expense" in the Consolidated Statements of Income has been adjusted to include the effects of interest accrued on the swaps. The Company, at times, utilizes derivatives to hedge the forecasted issuance of fixed-rate debt. These derivatives are designated as cash flow hedges of the variability in the fixed-rate coupon of the debt expected to be issued. The effective portion of the change in fair value of the derivatives is recorded in "Accumulated other comprehensive loss" in the Consolidated Balance Sheets. The Company held interest rate swaps in an aggregate notional amount of $975.0 million as of December 31, 2015 and 2014 . Of this aggregate notional amount held at December 31, 2015, $500.0 million related to notes due in 2017, $300.0 million related to notes due in 2018, and $175.0 million related to notes due in 2020. Balance Sheet The following table summarizes the fair value of derivatives reported in the Consolidated Balance Sheets as of December 31, 2015 and December 31, 2014 (in millions): Derivative Assets Derivative Liabilities Fair Value Fair Value Balance Sheet Location December 31, December 31, Balance Sheet Location December 31, December 31, Derivatives — hedges: Interest rate fair value hedges — Corporate Other assets $ 7.6 $ 3.5 Other liabilities $ — $ 1.9 Foreign currency cash flow hedges — Consumer-to-Consumer Other assets 59.7 66.1 Other liabilities 2.4 3.5 Total $ 67.3 $ 69.6 $ 2.4 $ 5.4 Derivatives — undesignated: Foreign currency — Business Solutions (a) Other assets $ 326.1 $ 349.4 Other liabilities $ 277.1 $ 310.2 Foreign currency — Consumer-to-Consumer Other assets 2.9 4.0 Other liabilities 4.2 1.5 Total $ 329.0 $ 353.4 $ 281.3 $ 311.7 Total derivatives $ 396.3 $ 423.0 $ 283.7 $ 317.1 ____________________ (a) In many circumstances, the Company allows its Business Solutions customers to settle part or all of their derivative contracts prior to maturity. However, the offsetting positions originally entered into with financial institution counterparties do not allow for similar settlement. To mitigate this, additional foreign currency contracts are entered into with financial institution counterparties to offset the original economic hedge contracts. This frequently results in increases in our derivative assets and liabilities that may exceed the growth in the underlying derivatives business. The following table summarizes the net fair value of derivatives held as of December 31, 2015 and their expected maturities (in millions): Total 2016 2017 2018 2019 2020 Thereafter Foreign currency cash flow hedges — Consumer-to-Consumer $ 57.3 $ 50.3 $ 7.0 $ — $ — $ — $ — Foreign currency undesignated hedges — Consumer-to-Consumer (1.3 ) (1.3 ) — — — — — Foreign currency undesignated hedges — Business Solutions 49.0 46.6 2.4 — — — — Interest rate fair value hedges — Corporate 7.6 — 1.2 1.6 — 4.8 — Total $ 112.6 $ 95.6 $ 10.6 $ 1.6 $ — $ 4.8 $ — The fair values of derivative assets and liabilities associated with contracts that include netting language that the Company believes to be enforceable have been netted in the following tables to present the Company's net exposure with these counterparties. The Company's rights under these agreements generally allow for transactions to be settled on a net basis, including upon early termination, which could occur upon the counterparty's default, a change in control, or other conditions. In addition, certain of the Company's other agreements include netting provisions, the enforceability of which may vary from jurisdiction to jurisdiction and depending on the circumstances. Due to the uncertainty related to the enforceability of these provisions, the derivative balances associated with these agreements are included within "Derivatives that are not or may not be subject to master netting arrangement or similar agreement" in the following tables. In certain circumstances, the Company may require its Business Solutions customers to maintain collateral balances which may mitigate the risk associated with potential customer defaults. The following tables summarize the gross and net fair value of derivative assets and liabilities as of December 31, 2015 and December 31, 2014 (in millions): Offsetting of Derivative Assets December 31, 2015 Gross Amounts of Recognized Assets Gross Amounts Offset in the Consolidated Balance Sheets Net Amounts Presented in the Consolidated Balance Sheets Derivatives Not Offset in the Consolidated Balance Sheets Net Amounts Derivatives subject to a master netting arrangement or similar agreement $ 224.3 $ — $ 224.3 $ (119.2 ) $ 105.1 Derivatives that are not or may not be subject to master netting arrangement or similar agreement 172.0 Total $ 396.3 December 31, 2014 Derivatives subject to a master netting arrangement or similar agreement $ 255.1 $ — $ 255.1 $ (134.8 ) $ 120.3 Derivatives that are not or may not be subject to master netting arrangement or similar agreement 167.9 Total $ 423.0 Offsetting of Derivative Liabilities December 31, 2015 Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Consolidated Balance Sheets Net Amounts Presented in the Consolidated Balance Sheets Derivatives Not Offset in the Consolidated Balance Sheets Net Amounts Derivatives subject to a master netting arrangement or similar agreement $ 169.6 $ — $ 169.6 $ (119.2 ) $ 50.4 Derivatives that are not or may not be subject to master netting arrangement or similar agreement 114.1 Total $ 283.7 December 31, 2014 Derivatives subject to a master netting arrangement or similar agreement $ 169.3 $ — $ 169.3 $ (134.8 ) $ 34.5 Derivatives that are not or may not be subject to master netting arrangement or similar agreement 147.8 Total $ 317.1 Income Statement The following tables summarize the location and amount of gains and losses of derivatives in the Consolidated Statements of Income segregated by designated, qualifying hedging instruments and those that are not, for the years ended December 31, 2015 , 2014 and 2013 (in millions): Fair Value Hedges The following table presents the location and amount of gains/(losses) from fair value hedges for the years ended December 31, 2015 , 2014 and 2013 (in millions): Gain/(Loss) Recognized in Income on Derivatives Gain/(Loss) Recognized in Income on Related Hedged Item (a) Gain/(Loss) Recognized in Income on Derivatives (Ineffective Portion and Amount Excluded from Effectiveness Testing) Income Statement Location Amount Income Statement Location Amount Income Statement Location Amount Derivatives 2015 2014 2013 Hedged Item 2015 2014 2013 2015 2014 2013 Interest rate contracts Interest expense $ 15.2 $ 17.5 $ (8.5 ) Fixed-rate debt Interest expense $ (2.3 ) $ (4.4 ) $ 19.3 Interest expense $ 0.8 $ (0.7 ) $ — Total gain/(loss) $ 15.2 $ 17.5 $ (8.5 ) $ (2.3 ) $ (4.4 ) $ 19.3 $ 0.8 $ (0.7 ) $ — Cash Flow Hedges The following table presents the location and amount of gains/(losses) from cash flow hedges for the years ended December 31, 2015 , 2014 and 2013 (in millions): Gain/(Loss) Recognized Gain/(Loss) Reclassified Gain/(Loss) Recognized in Income on in OCI on Derivatives from Accumulated OCI into Income Derivatives (Ineffective Portion and Amount (Effective Portion) (Effective Portion) Excluded from Effectiveness Testing) (b) Amount Income Statement Location Amount Income Statement Location Amount Derivatives 2015 2014 2013 2015 2014 2013 2015 2014 2013 Foreign currency contracts $ 70.8 $ 84.0 $ (3.1 ) Revenue $ 77.8 $ 1.6 $ 10.4 Derivative $ (0.1 ) $ (4.4 ) $ (0.4 ) Interest rate contracts (c) — — — Interest expense (3.6 ) (3.6 ) (3.6 ) Interest expense — — — Total gain/(loss) $ 70.8 $ 84.0 $ (3.1 ) $ 74.2 $ (2.0 ) $ 6.8 $ (0.1 ) $ (4.4 ) $ (0.4 ) Undesignated Hedges The following table presents the location and amount of net gains/(losses) from undesignated hedges for the years ended December 31, 2015 , 2014 and 2013 (in millions): Gain/(Loss) Recognized in Income on Derivatives (d) Income Statement Location Amount Derivatives 2015 2014 2013 Foreign currency contracts (e) Selling, general and administrative $ 35.9 $ 46.5 $ (3.7 ) Foreign currency contracts (f) Derivative gains/(losses), net 1.3 2.2 (0.9 ) Total gain/(loss) $ 37.2 $ 48.7 $ (4.6 ) ____________________ (a) The 2015 loss of $2.3 million was comprised of a loss in value on the debt of $16.0 million and amortization of hedge accounting adjustments of $13.7 million . The 2014 loss of $4.4 million was comprised of a loss in value on the debt of $16.8 million and amortization of hedge accounting adjustments of $12.4 million . The 2013 gain of $19.3 million was comprised of a gain in value on the debt of $8.5 million and amortization of hedge accounting adjustments of $10.8 million . (b) The portion of the change in fair value of a derivative excluded from the effectiveness assessment for foreign currency forward contracts designated as cash flow hedges represents the difference between changes in forward rates and spot rates. (c) The Company uses derivatives to hedge the forecasted issuance of fixed-rate debt and records the effective portion of the derivative's fair value in "Accumulated other comprehensive loss" in the Consolidated Balance Sheets. These amounts are reclassified to "Interest expense" in the Consolidated Statements of Income over the life of the related notes. (d) The Company uses foreign currency forward and option contracts as part of its Business Solutions payments operations. These derivative contracts are excluded from this table as they are managed as part of a broader currency portfolio that includes non-derivative currency exposures. The gains and losses on these derivatives are included as part of the broader disclosure of portfolio revenue for this business discussed above. (e) The Company uses foreign currency forward contracts to offset foreign exchange rate fluctuations on settlement assets and obligations as well as certain foreign currency denominated positions. Foreign exchange losses on settlement assets and obligations, cash balances, and other assets and liabilities, not including amounts related to derivatives activity as displayed above and included in "Selling, general, and administrative" in the Consolidated Statements of Income were $36.1 million , $51.8 million and $5.4 million for the years ended 2015 , 2014 and 2013 , respectively. (f) The derivative contracts used in the Company's revenue hedging program are not designated as hedges in the final month of the contract. An accumulated other comprehensive pre-tax gain of $51.5 million related to the foreign currency forward contracts is expected to be reclassified into revenue within the next 12 months as of December 31, 2015 . Approximately $3.6 million of net losses on the forecasted debt issuance hedges are expected to be recognized in "Interest expense" in the Consolidated Statements of Income within the next 12 months as of December 31, 2015 . No amounts have been reclassified into earnings as a result of the underlying transaction being considered probable of not occurring within the specified time period.

Borrowings	Borrowings The Company’s outstanding borrowings consisted of the following (in millions): December 31, 2015 December 31, 2014 Notes: Floating rate notes due 2015 $ — $ 250.0 2.375% notes due 2015 (a) — 250.0 5.930% notes due 2016 (a) 1,000.0 1,000.0 2.875% notes (effective rate of 2.1%) due 2017 500.0 500.0 3.650% notes due 2018 (a) 400.0 400.0 3.350% notes due 2019 (a) 250.0 250.0 5.253% notes due 2020 (a) 324.9 324.9 6.200% notes due 2036 (a) 500.0 500.0 6.200% notes due 2040 (a) 250.0 250.0 Other borrowings 5.5 5.6 Total borrowings at par value 3,230.4 3,730.5 Fair value hedge accounting adjustments, net (b) 7.6 5.3 Unamortized discount, net (12.4 ) (15.4 ) Total borrowings at carrying value (c) $ 3,225.6 $ 3,720.4 ____________________ (a) The difference between the stated interest rate and the effective interest rate is not significant. (b) The Company utilizes interest rate swaps designated as fair value hedges to effectively change the interest rate payments on a portion of its notes from fixed-rate payments to short-term LIBOR-based variable rate payments in order to manage its overall exposure to interest rates. The changes in fair value of these interest rate swaps result in an offsetting hedge accounting adjustment recorded to the carrying value of the related note. These hedge accounting adjustments will be reclassified as reductions to or increases in "Interest expense" in the Consolidated Statements of Income over the life of the related notes, and cause the effective rate of i nterest to differ from the notes’ stated rate. (c) As of December 31, 2015 , the Company’s weighted-average effective rate on total borrowings was approximately 4.8% . The following summarizes the Company's maturities of borrowings at par value as of December 31, 2015 (in millions): Due within 1 year $ 1,000.0 Due after 1 year through 2 years 505.5 Due after 2 years through 3 years 400.0 Due after 3 years through 4 years 250.0 Due after 4 years through 5 years 324.9 Due after 5 years 750.0 The Company’s obligations with respect to its outstanding notes, as described below, rank equally. Commercial Paper Program Pursuant to the Company’s commercial paper program, the Company may issue unsecured commercial paper notes in an amount not to exceed $1.5 billion outstanding at any time, reduced to the extent of borrowings outstanding on the Company’s Revolving Credit Facility in excess of $150 million . The Commercial Paper Notes may have maturities of up to 397 days from date of issuance. The Company had no commercial paper borrowings outstanding as of December 31, 2015 and 2014 . Revolving Credit Facility On September 29, 2015, the Company entered into a credit agreement which expires in September 2020 providing for unsecured financing facilities in an aggregate amount of $1.65 billion , including a $250.0 million letter of credit sub-facility ("Revolving Credit Facility"). The Revolving Credit Facility replaced the Company's $1.65 billion revolving credit facility that was set to expire in January 2017. The Revolving Credit Facility contains certain covenants that, among other things, limit or restrict the Company's ability to sell or transfer assets or merge or consolidate with another company, grant certain types of security interests, incur certain types of liens, impose restrictions on subsidiary dividends, enter into sale and leaseback transactions, incur certain subsidiary level indebtedness, subject to certain exceptions, or use proceeds in violation of applicable anti-corruption or AML laws. Also, consistent with the prior facility, the Company is required to maintain compliance with a consolidated interest coverage ratio covenant. The Revolving Credit Facility supports borrowings under the Company’s $1.5 billion commercial paper program. Interest due under the Revolving Credit Facility is fixed for the term of each borrowing and is payable according to the terms of that borrowing. Generally, interest is calculated using a selected LIBOR rate plus an interest rate margin of 110 basis points. A facility fee of 15 basis points is also payable quarterly on the total facility, regardless of usage. Both the interest rate margin and facility fee percentage are based on certain of the Company’s credit ratings. As of and during the years ended December 31, 2015 and 2014 , the Company had no outstanding borrowings under the revolving credit facilities. Notes On November 22, 2013, the Company issued $250.0 million of aggregate principal amount of unsecured notes due May 22, 2019 ("2019 Notes"). Interest with respect to the 2019 Notes is payable semi-annually in arrears on May 22 and November 22 of each year, beginning on May 22, 2014, based on the fixed per annum rate of 3.350% .

However, in no event will the interest rate on the 2019 Notes be increased by more than 2.00% above 3.350% per annum. The interest rate payable on the 2019 Notes may also be adjusted downward for debt rating upgrades subsequent to any debt rating downgrades but may not be adjusted below 3.350% per annum. The 2019 Notes are subject to covenants that, among other things, limit or restrict the ability of the Company to sell or transfer assets or merge or consolidate with another company, and limit or restrict the Company's and certain of its subsidiaries' ability to incur certain types of security interests, or enter into sale and leaseback transactions.

On December 10, 2012, the Company issued $250.0 million and $500.0 million of aggregate principal amounts of unsecured notes due December 10, 2015 ("2015 Fixed Rate Notes") and December 10, 2017 ("2017 Notes"), respectively. The 2015 Fixed Rate Notes matured and were repaid from the Company's cash balances in December 2015. Interest with respect to the 2017 Notes is payable semi-annually in arrears on June 10 and December 10 of each year, currently based on the per annum rate of 2.875% . The interest rate payable on the 2017 Notes will be increased if the debt rating assigned to such notes is downgraded by an applicable credit rating agency, beginning at a downgrade below investment grade. However, in no event will the interest rate on the 2017 Notes be increased by more than 2.00% above 2.875% per annum. The interest rate on the 2017 Notes may also be adjusted downward for debt rating upgrades subsequent to any debt rating downgrades but may not be adjusted below 2.875% per annum. The 2017 Notes are subject to covenants that, among other things, limit or restrict the ability of the Company to sell or transfer assets or merge or consolidate with another company, and limit or restrict the Company’s and certain of its subsidiaries’ ability to incur certain types of security interests, or enter into sale and leaseback transactions. The Company may redeem the 2017 Notes at any time prior to maturity at the greater of par or a price based on the applicable treasury rate plus 40 basis points.

Interest with respect to the 2040 Notes is payable semi-annually on June 21 and December 21 each year based on the fixed per annum rate of 6.200% . The 2040 Notes are subject to covenants that, among other things, limit or restrict the Company’s and certain of its subsidiaries’ ability to grant certain types of security interests or enter into sale and leaseback transactions. The Company may redeem the 2040 Notes at any time prior to maturity at the greater of par or a price based on the applicable treasury rate plus 30 basis points. On March 30, 2010, the Company exchanged $303.7 million of aggregate principal amount of unsecured notes due November 17, 2011 for unsecured notes due April 1, 2020 ("2020 Notes"). Interest with respect to the 2020 Notes is payable semi-annually on April 1 and October 1 each year based on the fixed per annum rate of 5.253% . In connection with the exchange, note holders were given a 7% premium ( $21.2 million ), which approximated market value at the exchange date, as additional principal. As this transaction was accounted for as a debt modification, this premium was not charged to expense. Rather, the premium, along with the offsetting hedge accounting adjustments, will be accreted into "Interest expense" over the life of the notes. The 2020 Notes are subject to covenants that, among other things, limit or restrict the Company’s and certain of its subsidiaries’ ability to grant certain types of security interests, incur debt (in the case of significant subsidiaries), or enter into sale and leaseback transactions.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Compensation Plans	Stock Compensation Plans Stock Compensation Plans The Western Union Company 2006 Long-Term Incentive Plan and 2015 Long-Term Incentive Plan The Western Union Company 2015 Long-Term Incentive Plan ("2015 LTIP"), approved on May 15, 2015, provides for the granting of stock options, restricted stock awards and units, unrestricted stock awards and units, and other equity-based awards to employees and non-employee directors of the Company. Prior to this, equity-based awards were granted out of the 2006 Long-Term Incentive Plan ("2006 LTIP"). Shares available for grant under the 2015 LTIP were 31.5 million as of December 31, 2015 . Options granted under the 2015 LTIP and the 2006 LTIP are issued with exercise prices equal to the fair market value of Western Union common stock on the grant date, have 10 -year terms, and typically vest over four equal annual increments beginning 12 months after the date of grant, with the exception of options granted to retirement eligible employees, which generally will vest on a prorated basis, upon termination. Compensation expense related to stock options is recognized over the requisite service period, which is the same as the vesting period. Restricted stock unit grants typically vest over four equal annual increments beginning 12 months after the date of grant. Restricted stock units granted prior to 2014 typically become 100% vested on the three year anniversary of the grant date. Restricted stock units granted to retirement eligible employees generally vest on a prorated basis upon termination. The fair value of the awards granted is measured based on the fair value of the shares on the date of grant. The majority of stock unit grants do not provide for the payment of dividend equivalents. For those grants, the value of the grants is reduced by the net present value of the foregone dividend equivalent payments. The related compensation expense is recognized over the requisite service period, which is the same as the vesting period. The compensation committee of the Company's Board of Directors has granted the Company's executives and certain other key employees long-term incentive awards under the 2015 LTIP and 2006 LTIP, which in 2015 and 2014 consisted of 80% performance-based restricted stock unit awards and 20% stock option awards. The compensation committee granted the remaining non-executive employees of the Company participating in the 2015 LTIP and 2006 LTIP (other than those non-executive employees receiving the performance-based restricted stock units described above) annual equity grants consisting solely of restricted stock units for 2015 and 2014. The performance-based restricted stock units granted in 2015 are restricted stock units, primarily granted to the Company's executives and consist of two separate awards. The first award consists of performance-based restricted stock units, which require the Company to meet certain financial objectives during 2015, 2016 and 2017. The second award consists of performance-based restricted stock units with a market condition tied to the Company's total shareholder return in relation to the S&P 500 Index as calculated over a three -year performance period (2015 through 2017). The actual number of performance-based restricted stock units that the recipients will receive for both 2015 awards will range from 0% up to 150% of the target number of stock units granted based on actual financial and total shareholder return performance results. The performance-based restricted stock units granted in 2014 were designed similar to the 2015 awards described above. The grant date fair value of the performance-based restricted stock units is fixed and the amount of restricted stock units that will ultimately vest depends upon the level of achievement of the performance and market conditions over the performance period. The fair value of the performance-based restricted stock units that are tied solely to performance conditions is measured similar to the restricted stock units discussed above, while the fair value of the performance-based restricted stock units that are tied to a market condition is determined using the Monte-Carlo simulation model. Unlike the performance-based awards that are tied solely to performance conditions, compensation costs related to awards with market conditions are recognized regardless of whether the market condition is satisfied, provided that the requisite service period has been completed. The Company also grants bonus/deferred stock units out of the 2015 LTIP and 2006 LTIP to the non-employee directors of the Company. Since bonus/deferred stock units vest immediately, compensation expense is recognized on the date of grant based on the fair value of the awards when granted. These awards may be settled immediately unless the participant elects to defer the receipt of common shares under the applicable plan rules. Stock Option Activity A summary of stock option activity for the year ended December 31, 2015 was as follows (options and aggregate intrinsic value in millions): Year Ended December 31, 2015 Options Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Outstanding as of January 1 16.4 $ 17.80 Granted 1.0 $ 19.32 Exercised (4.6 ) $ 17.25 Cancelled/forfeited (1.0 ) $ 19.20 Outstanding as of December 31 11.8 $ 18.01 4.4 $ 13.3 Options exercisable as of December 31 8.8 $ 18.62 3.3 $ 7.2 The Company received $80.1 million , $14.2 million and $28.6 million in cash proceeds related to the exercise of stock options during the years ended December 31, 2015 , 2014 and 2013 , respectively. Upon the exercise of stock options, shares of common stock are issued from authorized common shares. The Company realized total tax benefits during the years ended December 31, 2015 , 2014 and 2013 from stock option exercises of $4.3 million , $0.9 million and $1.3 million , respectively. The total intrinsic value of stock options exercised during the years ended December 31, 2015 , 2014 and 2013 was $15.0 million , $3.5 million and $4.2 million , respectively. Restricted Stock Activity A summary of activity for restricted stock units and performance-based restricted stock units for the year ended December 31, 2015 is listed below (units in millions): Year Ended December 31, 2015 Number Outstanding Weighted-Average Grant-Date Fair Value Non-vested as of January 1 7.6 $ 14.68 Granted 2.9 $ 17.85 Vested (2.0) $ 15.86 Forfeited (0.9) $ 15.64 Non-vested as of December 31 7.6 $ 15.47 Stock-Based Compensation The following table sets forth the total impact on earnings for stock-based compensation expense recognized in the Consolidated Statements of Income resulting from stock options, restricted stock units, performance-based restricted stock units and bonus/deferred stock units for the years ended December 31, 2015 , 2014 and 2013 (in millions, except per share data). Year Ended December 31, 2015 2014 2013 Stock-based compensation expense $ (42.2 ) $ (39.7 ) $ (34.5 ) Income tax benefit from stock-based compensation expense 12.3 11.5 10.0 Net income impact $ (29.9 ) $ (28.2 ) $ (24.5 ) Earnings per share: Basic and Diluted $ (0.06 ) $ (0.05 ) $ (0.04 ) As of December 31, 2015 , there was $5.0 million of total unrecognized compensation cost, net of assumed forfeitures, related to non-vested stock options which is expected to be recognized over a weighted-average period of 2.0 years, and there was $55.8 million of total unrecognized compensation cost, net of assumed forfeitures, related to non-vested restricted stock units and performance-based restricted stock units which is expected to be recognized over a weighted-average period of 2.4 years. Fair Value Assumptions The Company used the following assumptions for the Black-Scholes option pricing model to determine the value of Western Union options granted. Year Ended December 31, 2015 2014 2013 Stock options granted: Weighted-average risk-free interest rate 1.7 % 1.9 % 1.2 % Weighted-average dividend yield 3.6 % 3.1 % 3.7 % Volatility 28.2 % 33.8 % 35.3 % Expected term (in years) 6.00 6.09 6.09 Weighted-average grant date fair value $ 3.58 $ 3.95 $ 3.20 Risk-free interest rate - The risk-free rate for stock options granted during the period is determined by using a United States Treasury rate for the period that coincided with the expected terms listed above. Expected dividend yield - The Company's expected annual dividend yield is the calculation of the annualized Western Union dividend divided by an average Western Union stock price on each respective grant date. Expected volatility - For the Company's executives and non-employee directors, the expected volatility for the 2015, 2014 and 2013 grants was 28.2% , 33.8% and 35.3% , respectively. The expected volatility for the Company's non-executive employees was 35.2% for the 2013 grants. There were no options granted to non-executive employees in 2015 or 2014. The Company used a blend of implied and historical volatility. Volatility was calculated using the market price of traded options on Western Union's common stock and the historical volatility of Western Union stock data. Expected term - For 2015, 2014 and 2013, Western Union's expected term for all employees was approximately 6 years. The Company's expected term of options was based upon, among other things, historical exercises, the vesting term of the Company's options and the options' contractual term of ten years. The assumptions used to calculate the fair value of options granted are evaluated and revised, as necessary, to reflect market conditions and the Company's historical experience and future expectations. The calculated fair value is recognized as compensation cost in the Company's consolidated financial statements over the requisite service period of the entire award. Compensation cost is recognized only for those options expected to vest, with forfeitures estimated at the date of grant and evaluated and adjusted periodically to reflect the Company's historical experience and future expectations. Any change in the forfeiture assumption is accounted for as a change in estimate, with the cumulative effect of the change on periods previously reported being reflected in the consolidated financial statements of the period in which the change is made. In the future, as more historical data is available to calculate the volatility of Western Union stock and the actual terms Western Union employees hold options, expected volatility and expected term may change which could change the grant-date fair value of future stock option awards and, ultimately, the recorded compensation expense.

Segment Reporting [Abstract]
Segments	Segments As previously described in Note 1, the Company classifies its businesses into three segments: Consumer-to-Consumer, Consumer-to-Business and Business Solutions. Operating segments are defined as components of an enterprise that engage in business activities, about which separate financial information is available that is evaluated regularly by the Company's Chief Operating Decision Maker ("CODM") in deciding where to allocate resources and in assessing performance. The Consumer-to-Consumer operating segment facilitates money transfers between two consumers. The Company's money transfer service is viewed by the Company as one interconnected global network where a money transfer can be sent from one location to another, around the world. The segment includes five geographic regions whose functions are limited to generating, managing and maintaining agent relationships and localized marketing activities, and also includes online money transfer services conducted through Western Union branded websites ("westernunion.com"). By means of common processes and systems, these regions and westernunion.com create an interconnected network for consumer transactions, thereby constituting one global Consumer-to-Consumer money transfer business and one operating segment. The Consumer-to-Business operating segment facilitates bill payments from consumers to businesses and other organizations, including utilities, auto finance companies, mortgage servicers, financial service providers, government agencies and other businesses. The Business Solutions operating segment facilitates payment and foreign exchange solutions, primarily cross-border, cross-currency transactions, for small and medium size enterprises and other organizations and individuals. All businesses that have not been classified in the above segments are reported as "Other" and include the Company's money order and other services. The Company's reportable segments are reviewed separately below because each reportable segment represents a strategic business unit that offers different products and serves different markets. The business segment measurements provided to, and evaluated by, the Company's CODM are computed in accordance with the following principles: • The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. • Corporate and other overhead is allocated to the segments primarily based on a percentage of the segments' revenue compared to total revenue. • Costs incurred for the review and closing of acquisitions are included in "Other." • All items not included in operating income are excluded from the segments. The following tables present the Company's reportable segment results for the years ended December 31, 2015 , 2014 and 2013 , respectively (in millions): Year Ended December 31, 2015 2014 2013 Revenues: Consumer-to-Consumer: Transaction fees $ 3,221.0 $ 3,421.8 $ 3,396.1 Foreign exchange revenues 1,057.1 998.9 981.3 Other revenues 65.8 65.1 56.2 4,343.9 4,485.8 4,433.6 Consumer-to-Business: Transaction fees 612.7 572.7 579.1 Foreign exchange and other revenues 25.0 26.1 29.4 637.7 598.8 608.5 Business Solutions: Foreign exchange revenues 357.2 363.1 355.5 Transaction fees and other revenues 41.5 41.5 37.4 398.7 404.6 392.9 Other: Total revenues 103.4 118.0 107.0 Total consolidated revenues $ 5,483.7 $ 5,607.2 $ 5,542.0 Operating income/(loss): Consumer-to-Consumer $ 1,042.0 $ 1,050.4 $ 1,030.4 Consumer-to-Business (a) 68.6 98.7 121.9 Business Solutions (b) 2.8 (12.1 ) (27.0 ) Other (4.0 ) 3.5 (17.9 ) Total consolidated operating income $ 1,109.4 $ 1,140.5 $ 1,107.4 ____________________ (a) During the year ended December 31, 2015 , Consumer-to-Business operating income included $35.3 million of expenses related to the Paymap Settlement Agreement.

For transactions originated and paid in different regions, the Company splits the revenue between the two regions, with each region receiving 50% . For money transfers initiated and paid in the same region, 100% of the revenue is attributed to that region. The geographic split of revenue above for the Consumer-to-Business and Business Solutions segments is based upon the country where the transaction is initiated with 100% of the revenue allocated to that country. Long-lived assets, consisting of "Property and equipment, net," are presented based upon the location of the assets. Based on the method used to attribute revenue between countries described in the paragraph above, each individual country outside the United States accounted for less than 10% of consolidated revenue for the years ended December 31, 2015 , 2014 and 2013 , respectively. In addition, each individual agent, Consumer-to-Business, or Business Solutions customer accounted for less than 10% of consolidated revenue during these periods.

Summary of Significant Accoun27

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The financial statements in this Annual Report on Form 10-K are presented on a consolidated basis and include the accounts of the Company and its majority-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated. Consistent with industry practice, the accompanying Consolidated Balance Sheets are unclassified due to the short-term nature of the Company's settlement obligations contrasted with the Company's ability to invest cash awaiting settlement in long-term investment securities.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates.
Principles of Consolidation	Principles of Consolidation The Company consolidates financial results when it has both the power to direct the activities of an entity that most significantly impact the entity's economic performance and the ability to absorb losses or the right to receive benefits of the entity that could potentially be significant to the entity. The Company utilizes the equity method of accounting when it is able to exercise significant influence over the entity's operations, which generally occurs when the Company has an ownership interest of between 20% and 50% in an entity.
Earnings Per Share	Earnings Per Share The calculation of basic earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Outstanding options to purchase Western Union stock and unvested shares of restricted stock are excluded from basic shares outstanding. Diluted earnings per share reflects the potential dilution that could occur if outstanding stock options at the presented dates are exercised and shares of restricted stock have vested, using the treasury stock method. The treasury stock method assumes proceeds from the exercise price of stock options, the unamortized compensation expense and assumed tax benefits of options and restricted stock are available to acquire shares at an average market price throughout the period, and therefore, reduce the dilutive effect.
Fair Value Measurements	Fair Value Measurements The Company determines the fair values of its assets and liabilities that are recognized or disclosed at fair value in accordance with the hierarchy described below. The fair values of the assets and liabilities held in the Company's defined benefit plan trust ("Trust") are recognized or disclosed utilizing the same hierarchy. The following three levels of inputs may be used to measure fair value: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. For most of these assets, the Company utilizes pricing services that use multiple prices as inputs to determine daily market values. In addition, the Trust has other investments that fall within Level 2 that are valued at net asset value which is not quoted on an active market; however, the unit price is based on underlying investments which are traded on an active market. The individual redemption restrictions of Trust investments measured at net asset value are also considered when determining whether Level 2 classification is appropriate. • Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include items where the determination of fair value requires significant management judgment or estimation. The Company has Level 3 assets that are recognized and disclosed at fair value on a non-recurring basis related to the Company's business combinations, where the values of the intangible assets and goodwill acquired in a purchase are derived utilizing one of the three recognized approaches: the market approach, the income approach or the cost approach. Carrying amounts for many of the Company's financial instruments, including cash and cash equivalents, settlement cash and cash equivalents, and settlement receivables and settlement obligations approximate fair value due to their short maturities. Investment securities and derivative financial instruments are carried at fair value and included in Note 8. Fixed rate notes are carried at their original issuance values as adjusted over time to accrete that value to par, except for portions of notes hedged by interest rate swap agreements as disclosed in Note 14. The fair values of fixed rate notes are also disclosed in Note 8 and are based on market quotations. For more information on the fair value of financial instruments, see Note 8. The fair values of non-financial assets and liabilities related to the Company's business combinations are disclosed in Note 4.
Business Combinations	Business Combinations The Company accounts for all business combinations where control over another entity is obtained using the acquisition method of accounting, which requires that most assets (both tangible and intangible), liabilities (including contingent consideration), and remaining noncontrolling interests be recognized at fair value at the date of acquisition. The excess of the purchase price over the fair value of assets less liabilities and noncontrolling interests is recognized as goodwill. Certain adjustments to the assessed fair values of the assets, liabilities, or noncontrolling interests made subsequent to the acquisition date, but within the measurement period, which is one year or less, are recorded as adjustments to goodwill. Any adjustments subsequent to the measurement period are recorded in income. Any cost or equity method interest that the Company holds in the acquired company prior to the acquisition is remeasured to fair value at acquisition with a resulting gain or loss recognized in income for the difference between fair value and existing book value. Results of operations of the acquired company are included in the Company's results from the date of the acquisition forward and include amortization expense arising from acquired intangible assets. The Company expenses all costs as incurred related to or involved with an acquisition in "Selling, general and administrative" expenses.
Cash and Cash Equivalents	Cash and Cash Equivalents Highly liquid investments (other than those included in settlement assets) with maturities of three months or less at the date of purchase (that are readily convertible to cash) are considered to be cash equivalents and are stated at cost, which approximates fair value. The Company maintains cash and cash equivalent balances, including a portion in money market funds, with a group of globally diversified banks and financial institutions. The Company limits the concentration of its cash and cash equivalents with any one institution and regularly reviews investment concentrations and credit worthiness of these institutions
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The Company records an allowance for doubtful accounts when it is probable that the related receivable balance will not be collected based on its history of collection experience, known collection issues, such as agent suspensions and bankruptcies, consumer chargebacks and insufficient funds, and other matters the Company identifies in its routine collection monitoring.
Settlement Assets and Obligations	Settlement Assets and Obligations Settlement assets represent funds received or to be received from agents for unsettled money transfers, money orders and consumer payments. The Company records corresponding settlement obligations relating to amounts payable under money transfers, money orders and consumer payment service arrangements. Settlement assets and obligations also include amounts receivable from, and payable to, customers for the value of their cross-currency payment transactions related to the Business Solutions segment. Settlement assets consist of cash and cash equivalents, receivables from selling agents and Business Solutions customers, and investment securities. Cash received by Western Union agents generally becomes available to the Company within one week after initial receipt by the agent. Cash equivalents consist of short-term time deposits, commercial paper and other highly liquid investments. Receivables from selling agents represent funds collected by such agents, but in transit to the Company. Western Union has a large and diverse agent base, thereby reducing the credit risk of the Company from any one agent. In addition, the Company performs ongoing credit evaluations of its agents' financial condition and credit worthiness. See Note 7 for information concerning the Company's investment securities. Receivables from Business Solutions customers arise from cross-currency payment transactions in the Business Solutions segment. Receivables occur when funds have been paid out to a beneficiary but not yet received from the customer. Aside from these receivables, the credit risk associated with spot foreign currency exchange contracts is largely mitigated, as in most cases the Company requires the receipt of funds from customers before releasing the associated cross-currency payment. Settlement obligations consist of money transfer, money order and payment service payables and payables to agents. Money transfer payables represent amounts to be paid to transferees when they request their funds. Most agents typically settle with transferees first and then obtain reimbursement from the Company. Money order payables represent amounts not yet presented for payment. Payment service payables represent amounts to be paid to utility companies, auto finance companies, mortgage servicers, financial service providers, government agencies and others. Due to the agent funding and settlement process, payables to agents represent amounts due to agents for money transfers that have been settled with transferees.
Property and Equipment	Property and Equipment Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the lesser of the estimated life of the related assets (generally three to ten years for equipment and furniture and fixtures, and 30 years for buildings) or the lease term. Maintenance and repairs, which do not extend the useful life of the respective assets, are charged to expense as incurred.
Goodwill	Goodwill Goodwill represents the excess of purchase price over the fair value of tangible and other intangible assets acquired, less liabilities assumed arising from business combinations.
Other Intangible Assets	Other Intangible Assets Other intangible assets primarily consist of acquired contracts, contract costs (primarily amounts paid to agents in connection with establishing and renewing long-term contracts) and software. Other intangible assets are amortized on a straight-line basis over the length of the contract or benefit periods. Included in the Consolidated Statements of Income is amortization expense of $202.5 million , $205.3 million and $198.6 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Acquired contracts include customer and contractual relationships and networks of subagents that are recognized in connection with the Company's acquisitions. The Company capitalizes initial payments for new and renewed agent contracts to the extent recoverable through future operations or penalties in the case of early termination. The Company's accounting policy is to limit the amount of capitalized costs for a given contract to the lesser of the estimated future cash flows from the contract or the termination fees the Company would receive in the event of early termination of the contract. The Company purchases and develops software that is used in providing services and in performing administrative functions. Software development costs are capitalized once technological feasibility of the software has been established. Costs incurred prior to establishing technological feasibility are expensed as incurred. Technological feasibility is established when the Company has completed all planning and designing activities that are necessary to determine that a product can be produced to meet its design specifications, including functions, features and technical performance requirements. Capitalization of costs ceases when the product is available for general use. Software development costs and purchased software are generally amortized over a term of three to five years. Other intangible assets are reviewed for impairment on an annual basis or whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. In such reviews, estimated undiscounted cash flows associated with these assets or operations are compared with their carrying values to determine if a write-down to fair value (normally measured by the present value technique) is required.
Revenue Recognition	Revenue Recognition The Company's revenues are primarily derived from consumer money transfer transaction fees that are based on the principal amount of the money transfer and the locations from and to which funds are transferred. The Company also offers several payments services, including payments from consumers or businesses to other businesses. Transaction fees are set by the Company and recorded as revenue at the time of sale. In certain consumer money transfer, bill payment and Business Solutions transactions involving different send and receive currencies, the Company generates revenue based on the difference between the exchange rate set by the Company to the consumer or business and the rate at which the Company or its agents are able to acquire the currency. This foreign exchange revenue is recorded at the time the related consumer money transfer transaction fee revenue is recognized or at the time a customer initiates a transaction through the Company's Business Solutions payment service operations.
Cost of Services	Cost of Services Cost of services primarily consists of agent commissions and expenses for call centers, settlement operations and related information technology costs. Expenses within these functions include personnel, software, equipment, telecommunications, bank fees, depreciation, amortization and other expenses incurred in connection with providing money transfer and other payment services.
Advertising Costs	Advertising Costs Advertising costs are charged to operating expenses as incurred.
Income Taxes	Income Taxes The Company accounts for income taxes under the liability method, which requires that deferred tax assets and liabilities be determined based on the expected future income tax consequences of events that have been recognized in the consolidated financial statements. Deferred tax assets and liabilities are recognized based on temporary differences between the financial statement carrying amounts and tax bases of assets and liabilities using enacted tax rates in effect in the years in which the temporary differences are expected to reverse. The Company assesses the realizability of its deferred tax assets. A valuation allowance must be established when, based upon available evidence, it is more likely than not that all or a portion of the deferred tax assets will not be realized. The Company recognizes the tax benefits from uncertain tax positions only when it is more likely than not, based on the technical merits of the position, the tax position will be sustained upon examination, including the resolution of any related appeals or litigation. The tax benefits recognized in the consolidated financial statements from such a position are measured as the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution.
Foreign Currency Translation	Foreign Currency Translation The United States dollar is the functional currency for substantially all of the Company's businesses. Revenues and expenses are translated at average exchange rates prevailing during the period. Foreign currency denominated assets and liabilities for those businesses for which the local currency is the functional currency are translated into United States dollars based on exchange rates at the end of the year. The effects of foreign exchange gains and losses arising from the translation of assets and liabilities of these businesses are included as a component of "Accumulated other comprehensive loss" in the accompanying Consolidated Balance Sheets. Foreign currency denominated monetary assets and liabilities of businesses for which the United States dollar is the functional currency are remeasured based on exchange rates at the end of the period, and the resulting remeasurement gains and losses are recognized in net income. Non-monetary assets and liabilities of these operations are remeasured at historical rates in effect when the asset was recognized or the liability was incurred.
Derivatives	Derivatives The Company uses derivatives to (a) minimize its exposures related to changes in foreign currency exchange rates and interest rates and (b) facilitate cross-currency Business Solutions payments by writing derivatives to customers. The Company recognizes all derivatives in the "Other assets" and "Other liabilities" captions in the accompanying Consolidated Balance Sheets at their fair value. All cash flows associated with derivatives are included in cash flows from operating activities in the Consolidated Statements of Cash Flows. • Cash flow hedges - Changes in the fair value of derivatives that are designated and qualify as cash flow hedges are recorded in "Accumulated other comprehensive loss." Cash flow hedges consist of foreign currency hedging of forecasted revenues, as well as hedges of the forecasted issuance of fixed rate debt. Derivative fair value changes that are captured in "Accumulated other comprehensive loss" are reclassified to earnings in the same period or periods the hedged item affects earnings, to the extent the instrument is effective in offsetting the change in cash flows attributable to the risk being hedged. The portions of the change in fair value that are either considered ineffective or are excluded from the measure of effectiveness are recognized immediately in "Derivative gains/(losses), net." • Fair value hedges - Changes in the fair value of derivatives that are designated as fair value hedges of fixed rate debt are recorded in "Interest expense." The offsetting change in value of the related debt instrument attributable to changes in the benchmark interest rate is also recorded in "Interest expense." • Undesignated - Derivative contracts entered into to reduce the variability related to (a) money transfer settlement assets and obligations, generally with maturities from a few days up to one month, and (b) certain foreign currency denominated cash and other asset and liability positions, typically with maturities of less than one year at inception, are not designated as hedges for accounting purposes and changes in their fair value are included in "Selling, general and administrative." The Company is also exposed to risk from derivative contracts written to its customers arising from its cross-currency Business Solutions payments operations. The duration of these derivative contracts at inception is generally less than one year. The Company aggregates its Business Solutions payments foreign currency exposures arising from customer contracts, including the derivative contracts described above, and hedges the resulting net currency risks by entering into offsetting contracts with established financial institution counterparties (economic hedge contracts) as part of a broader foreign currency portfolio, including significant spot exchanges of currency in addition to forwards and options. The changes in fair value related to these contracts are recorded in "Foreign exchange revenues." The fair value of the Company's derivatives is derived from standardized models that use market based inputs (e.g., forward prices for foreign currency). The details of each designated hedging relationship are formally documented at the inception of the arrangement, including the risk management objective, hedging strategy, hedged item, specific risks being hedged, the derivative instrument, how effectiveness is being assessed and how ineffectiveness, if any, will be measured. The derivative must be highly effective in offsetting the changes in cash flows or fair value of the hedged item, and effectiveness is evaluated quarterly on a retrospective and prospective basis. The Company is exposed to foreign currency exchange risk resulting from fluctuations in exchange rates, primarily the euro, and to a lesser degree the British pound, Canadian dollar, Australian dollar, Swiss franc, and other currencies, related to forecasted money transfer revenues and on money transfer settlement assets and obligations as well as on certain foreign currency denominated cash and other asset and liability positions. The Company is also exposed to risk from derivative contracts written to its customers arising from its cross-currency Business Solutions payments operations. Additionally, the Company is exposed to interest rate risk related to changes in market rates both prior to and subsequent to the issuance of debt. The Company uses derivatives to (a) minimize its exposures related to changes in foreign currency exchange rates and interest rates and (b) facilitate cross-currency Business Solutions payments by writing derivatives to customers. The Company executes derivatives with established financial institutions, with the substantial majority of these financial institutions having credit ratings of "A-" or better from a major credit rating agency. The Company also writes Business Solutions derivatives mostly with small and medium size enterprises. The primary credit risk inherent in derivative agreements represents the possibility that a loss may occur from the nonperformance of a counterparty to the agreements. The Company performs a review of the credit risk of these counterparties at the inception of the contract and on an ongoing basis. The Company also monitors the concentration of its contracts with any individual counterparty. The Company anticipates that the counterparties will be able to fully satisfy their obligations under the agreements, but takes action when doubt arises about the counterparties' ability to perform. These actions may include requiring Business Solutions customers to post or increase collateral, and for all counterparties, the possible termination of the related contracts. The Company's hedged foreign currency exposures are in liquid currencies; consequently, there is minimal risk that appropriate derivatives to maintain the hedging program would not be available in the future.
Legal Contingencies	Legal Contingencies The Company is a party to certain legal and regulatory proceedings with respect to a variety of matters. The Company records an accrual for these contingencies to the extent that a loss is both probable and reasonably estimable. If some amount within a range of loss appears to be a better estimate than any other amount within the range, that amount is accrued. When no amount within a range of loss appears to be a better estimate than any other amount, the lowest amount in the range is accrued.
Stock-Based Compensation	Stock-Based Compensation The Company currently has a stock-based compensation plan that provides for grants of Western Union stock options, restricted stock awards and restricted and unrestricted stock units to employees and non-employee directors of the Company. All stock-based compensation to employees is required to be measured at fair value and expensed over the requisite service period and also requires an estimate of forfeitures when calculating compensation expense. The Company recognizes compensation expense on awards on a straight-line basis over the requisite service period for the entire award. Refer to Note 16 for additional discussion regarding details of the Company's stock-based compensation plans.
Severance and Other Related Expenses	Severance and Other Related Expenses The Company records severance-related expenses once they are both probable and estimable in accordance with the provisions of the applicable accounting guidance for severance provided under an ongoing benefit arrangement. One-time, involuntary benefit arrangements and other costs are generally recognized when the liability is incurred. The Company also evaluates impairment issues associated with restructuring and other activities when the carrying amount of the assets may not be fully recoverable, in accordance with the appropriate accounting guidance.
New Accounting Pronouncements	New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board issued a new accounting pronouncement regarding revenue from contracts with customers. This new standard provides guidance on recognizing revenue, including a five step model to determine when revenue recognition is appropriate. The standard requires that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company is required to adopt the new standard on January 1, 2018. Management is currently evaluating the potential impact that the adoption of this standard will have on the Company's financial position, results of operations, and related disclosures. In April 2015, the Financial Accounting Standards Board issued guidance on the financial statement presentation of debt issuance costs. This update requires capitalized debt issuance costs to be presented as a reduction to the carrying value of debt instead of being classified as a deferred charge, as currently required. The Company is required to adopt the new standard on January 1, 2016, with adoption retroactive for all periods presented. This update will not have a material impact on the presentation of the Company’s financial position, results of operations, and related disclosures. In January 2016, the Financial Accounting Standards Board issued a new accounting pronouncement regarding classification and measurement of financial instruments. This new standard provides guidance on how entities measure certain equity investments and present changes in the fair value. This standard requires that entities measure certain equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income. The Company is required to adopt the new standard on January 1, 2018. Management is currently evaluating the potential impact that the adoption of this standard will have on the Company's financial position, results of operations, and related disclosures.
Investment Securities	Investment Securities Investment securities included in "Settlement assets" in the Consolidated Balance Sheets consist primarily of highly-rated state and municipal debt securities, including fixed rate term notes and variable rate demand notes. Variable rate demand note securities can be put (sold at par) typically on a daily basis with settlement periods ranging from the same day to one week, but have varying maturities through 2049 . Generally, these securities are used by the Company for short-term liquidity needs and are held for short periods of time, typically less than 30 days . The Company is required to hold highly-rated, investment grade securities and such investments are restricted to satisfy outstanding settlement obligations in accordance with applicable state and foreign country requirements. The substantial majority of the Company's investment securities are classified as available-for-sale and recorded at fair value. Investment securities are exposed to market risk due to changes in interest rates and credit risk. Western Union regularly monitors credit risk and attempts to mitigate its exposure by investing in highly-rated securities and through investment diversification. Unrealized gains and losses on available-for-sale securities are excluded from earnings and presented as a component of accumulated other comprehensive income or loss, net of related deferred taxes. Proceeds from the sale and maturity of available-for-sale securities during the years ended December 31, 2015 , 2014 and 2013 were $8.7 billion , $17.7 billion and $19.0 billion , respectively. Gains and losses on investments are calculated using the specific-identification method and are recognized during the period in which the investment is sold or when an investment experiences an other-than-temporary decline in value. Factors that could indicate an impairment exists include, but are not limited to: earnings performance, changes in credit rating or adverse changes in the regulatory or economic environment of the asset. If potential impairment exists, the Company assesses whether it has the intent to sell the debt security, more likely than not will be required to sell the debt security before its anticipated recovery or expects that some of the contractual cash flows will not be received. The Company had no material other-than-temporary impairments during the periods presented.
Foreign Currency — Consumer-to-Consumer	Foreign Currency — Consumer-to-Consumer The Company's policy is to use longer-term foreign currency forward contracts, with maturities of up to 36 months at inception and a targeted weighted-average maturity of approximately one year, to help mitigate some of the risk that changes in foreign currency exchange rates compared to the United States dollar could have on forecasted revenues denominated in other currencies related to its business. As of December 31, 2015 , the Company's longer-term foreign currency forward contracts had maturities of a maximum of 24 months with a weighted-average maturity of approximately one year. These contracts are accounted for as cash flow hedges of forecasted revenue, with effectiveness assessed based on changes in the spot rate of the affected currencies during the period of designation. Accordingly, all changes in the fair value of the hedges not considered effective or portions of the hedge that are excluded from the measure of effectiveness are recognized immediately in "Derivative gains/(losses), net" within the Company's Consolidated Statements of Income. The Company also uses short duration foreign currency forward contracts, generally with maturities from a few days up to one month, to offset foreign exchange rate fluctuations on settlement assets and obligations between initiation and settlement. In addition, forward contracts, typically with maturities of less than one year at inception, are utilized to offset foreign exchange rate fluctuations on certain foreign currency denominated cash and other asset and liability positions. None of these contracts are designated as accounting hedges.
Foreign Currency — Business Solutions	Foreign Currency — Business Solutions The Company writes derivatives, primarily foreign currency forward contracts and option contracts, mostly with small and medium size enterprises and derives a currency spread from this activity as part of its Business Solutions operations. The Company aggregates its Business Solutions payments foreign currency exposures arising from customer contracts, including the derivative contracts described above, and hedges the resulting net currency risks by entering into offsetting contracts with established financial institution counterparties (economic hedge contracts). The derivatives written are part of the broader portfolio of foreign currency positions arising from the Company's cross-currency payments operations, which primarily include spot exchanges of currency in addition to forwards and options. The resulting foreign exchange revenues from the total portfolio of positions comprise Business Solutions foreign exchange revenues. None of the derivative contracts used in Business Solutions operations are designated as accounting hedges. The duration of these derivative contracts at inception is generally less than one year.
Interest Rate Hedging — Corporate	Interest Rate Hedging — Corporate The Company utilizes interest rate swaps to effectively change the interest rate payments on a portion of its notes from fixed-rate payments to short-term LIBOR-based variable rate payments in order to manage its overall exposure to interest rates. The Company designates these derivatives as fair value hedges. The change in fair value of the interest rate swaps is offset by a change in the carrying value of the debt being hedged within "Borrowings" in the Consolidated Balance Sheets and "Interest expense" in the Consolidated Statements of Income has been adjusted to include the effects of interest accrued on the swaps. The Company, at times, utilizes derivatives to hedge the forecasted issuance of fixed-rate debt. These derivatives are designated as cash flow hedges of the variability in the fixed-rate coupon of the debt expected to be issued. The effective portion of the change in fair value of the derivatives is recorded in "Accumulated other comprehensive loss" in the Consolidated Balance Sheets.

However, the offsetting positions originally entered into with financial institution counterparties do not allow for similar settlement. To mitigate this, additional foreign currency contracts are entered into with financial institution counterparties to offset the original economic hedge contracts. This frequently results in increases in our derivative assets and liabilities that may exceed the growth in the underlying derivatives business.

(c) The Company uses derivatives to hedge the forecasted issuance of fixed-rate debt and records the effective portion of the derivative's fair value in "Accumulated other comprehensive loss" in the Consolidated Balance Sheets. These amounts are reclassified to "Interest expense" in the Consolidated Statements of Income over the life of the related notes. (d) The Company uses foreign currency forward and option contracts as part of its Business Solutions payments operations. These derivative contracts are excluded from this table as they are managed as part of a broader currency portfolio that includes non-derivative currency exposures. The gains and losses on these derivatives are included as part of the broader disclosure of portfolio revenue for this business discussed above. (e) The Company uses foreign currency forward contracts to offset foreign exchange rate fluctuations on settlement assets and obligations as well as certain foreign currency denominated positions. Foreign exchange losses on settlement assets and obligations, cash balances, and other assets and liabilities, not including amounts related to derivatives activity as displayed above and included in "Selling, general, and administrative" in the Consolidated Statements of Income were $36.1 million , $51.8 million and $5.4 million for the years ended 2015 , 2014 and 2013 , respectively. (f) The derivative contracts used in the Company's revenue hedging program are not designated as hedges in the final month of the contract.

These hedge accounting adjustments will be reclassified as reductions to or increases in "Interest expense" in the Consolidated Statements of Income over the life of the related notes, and cause the effective rate of i nterest to differ from the notes’ stated rate. (c) As of December 31, 2015 , the Company’s weighted-average effective rate on total borrowings was approximately 4.8% .

[1]	In many circumstances, the Company allows its Business Solutions customers to settle part or all of their derivative contracts prior to maturity. However, the offsetting positions originally entered into with financial institution counterparties do not allow for similar settlement. To mitigate this, additional foreign currency contracts are entered into with financial institution counterparties to offset the original economic hedge contracts. This frequently results in increases in our derivative assets and liabilities that may exceed the growth in the underlying derivatives business.

[1]	The 2015 loss of $2.3 million was comprised of a loss in value on the debt of $16.0 million and amortization of hedge accounting adjustments of $13.7 million. The 2014 loss of $4.4 million was comprised of a loss in value on the debt of $16.8 million and amortization of hedge accounting adjustments of $12.4 million. The 2013 gain of $19.3 million was comprised of a gain in value on the debt of $8.5 million and amortization of hedge accounting adjustments of $10.8 million.
[2]	The portion of the change in fair value of a derivative excluded from the effectiveness assessment for foreign currency forward contracts designated as cash flow hedges represents the difference between changes in forward rates and spot rates.
[3]	The Company uses derivatives to hedge the forecasted issuance of fixed-rate debt and records the effective portion of the derivative's fair value in "Accumulated other comprehensive loss" in the Consolidated Balance Sheets. These amounts are reclassified to "Interest expense" in the Consolidated Statements of Income over the life of the related notes.
[4]	The Company uses foreign currency forward contracts to offset foreign exchange rate fluctuations on settlement assets and obligations as well as certain foreign currency denominated positions. Foreign exchange losses on settlement assets and obligations, cash balances, and other assets and liabilities, not including amounts related to derivatives activity as displayed above and included in "Selling, general, and administrative" in the Consolidated Statements of Income were $36.1 million, $51.8 million and $5.4 million for the years ended 2015, 2014 and 2013, respectively.
[5]	The derivative contracts used in the Company's revenue hedging program are not designated as hedges in the final month of the contract.

[1]	The Company utilizes interest rate swaps designated as fair value hedges to effectively change the interest rate payments on a portion of its notes from fixed-rate payments to short-term LIBOR-based variable rate payments in order to manage its overall exposure to interest rates. The changes in fair value of these interest rate swaps result in an offsetting hedge accounting adjustment recorded to the carrying value of the related note. These hedge accounting adjustments will be reclassified as reductions to or increases in "Interest expense" in the Consolidated Statements of Income over the life of the related notes, and cause the effective rate of interest to differ from the notes’ stated rate.
[2]	As of December 31, 2015, the Company’s weighted-average effective rate on total borrowings was approximately 4.8%.
[3]	The difference between the stated interest rate and the effective interest rate is not significant.
