Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The Brink’s Company (along with its subsidiaries, “we,” “our,” “Brink’s” or the “Company”), based in Richmond, Virginia, is a leading provider of secure transportation, cash management services and other security-related services to banks and financial institutions, retailers, government agencies, mints, jewelers and other commercial operations around the world. Brink’s is the oldest and largest secure transportation and cash management services company in the U.S., and a market leader in many other countries. Consolidation The consolidated financial statements include our controlled subsidiaries. Control is determined based on ownership rights or, when applicable, based on whether we are considered to be the primary beneficiary of a variable interest entity. See "Venezuela" section below for further information. For controlled subsidiaries that are not wholly-owned, the noncontrolling interests are included in net income and in total equity. Investments in businesses that we do not control, but for which we have the ability to exercise significant influence over operating and financial policies, are accounted for under the equity method and our proportionate share of income or loss is recorded in other operating income (expense). Investments in businesses for which we do not have the ability to exercise significant influence over operating and financial policies are accounted for at fair value, if readily determinable, with changes in fair value recognized in net income. For equity investments that do not have a readily determinable fair value, we measure these investments at cost minus impairment, if any, plus or minus changes from observable price changes. See "New Accounting Standards" section below for further information. All intercompany accounts and transactions have been eliminated in consolidation. Revenue Recognition Revenue is recognized when services related to armored vehicle transportation, ATM services, cash management services, payment services, guarding and the secure international transportation of valuables are performed. We assess our customers' ability to meet contractual terms, including payment terms, before entering into contracts. Taxes collected from customers and remitted to governmental authorities are not included in revenues in the consolidated statements of operations. On January 1, 2018, we adopted ASC 606, Revenue from Contracts with Customers , and applied the standard to all contracts using the modified retrospective method. Prior period amounts are not adjusted and continue to be reported in accordance with ASC 605, Revenue Recognition . See Note 2 for further information. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits and investments with original maturities of three months or less. Cash and cash equivalents include amounts held by certain of our secure cash management services operations for customers for which, under local regulations, the title transfers to us for a short period of time. The cash is generally credited to customers’ accounts the following day and we do not consider it as available for general corporate purposes in the management of our liquidity and capital resources. We record a liability for the amounts owed to customers (see Note 13). Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses on our existing accounts receivable. We determine the allowance based on historical write-off experience. We review our allowance for doubtful accounts quarterly. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Property and Equipment Property and equipment are recorded at cost. Depreciation is calculated principally on the straight-line method based on the estimated useful lives of individual assets or classes of assets. Leased property and equipment meeting capital lease criteria are capitalized at the lower of the present value of the related lease payments or the fair value of the leased asset at the inception of the lease. Amortization is calculated on the straight-line method based on the lease term. See "New Accounting Standards" section below for further information. Leasehold improvements are recorded at cost. Amortization is calculated principally on the straight-line method over the lesser of the estimated useful life of the leasehold improvement or the lease term. Renewal periods are included in the lease term when the renewal is determined to be reasonably assured. Part of the costs related to the development or purchase of internal-use software is capitalized and amortized over the estimated useful life of the software. Costs that are capitalized include external direct costs of materials and services to develop or obtain the software, and internal costs, including compensation and employee benefits for employees directly associated with a software development project. Estimated Useful Lives Years Buildings 16 to 25 Building leasehold improvements 3 to 10 Vehicles 3 to 10 Capitalized software 3 to 5 Other machinery and equipment 3 to 10 Expenditures for routine maintenance and repairs on property and equipment are charged to expense. Major renewals, betterments and modifications are capitalized and depreciated over the lesser of the remaining life of the asset or, if applicable, the lease term. Goodwill and Other Intangible Assets Goodwill is recognized for the excess of the purchase price over the fair value of tangible and identifiable intangible net assets of businesses acquired. Intangible assets arising from business acquisitions include customer lists, customer relationships, covenants not to compete, trademarks and other identifiable intangibles. At December 31, 2018 , finite-lived intangible assets have remaining useful lives ranging from 1 to 15 years and are amortized based on the pattern in which the economic benefits are used or on a straight-line basis. Impairment of Goodwill and Long-Lived Assets Goodwill is not amortized but is tested at least annually for impairment at the reporting unit level, which is one level below an operating segment. Goodwill is assigned to one or more reporting units at the date of acquisition. Effective February 2017, we implemented changes to our organization and management structure. After the February 2017 reorganization, we have eight reporting units: • U.S. • Mexico • Canada • France • Brazil • Global Markets - South America • Global Markets - EMEA • Global Markets - Asia We performed goodwill impairment tests on the reporting units that had goodwill as of October 1, 2018. We performed a quantitative analysis to determine whether reporting unit fair values exceeded their carrying amounts. We based our estimates of fair value on projected future cash flows. With one exception, we concluded that the fair value of each reporting unit substantially exceeded its carrying value by a range of 57% to 236% . For the France reporting unit, which has $91.2 million of goodwill at December 31, 2018, fair value exceeded carrying value by approximately 9% . We completed these impairment tests, as well as the tests in the previous two years, with no impairment charges required. Indefinite-lived intangibles are also tested for impairment at least annually by comparing their carrying values to their estimated fair values. We have had no significant impairments of indefinite-lived intangibles in the last three years. Long-lived assets other than goodwill and other indefinite-lived intangibles are reviewed for impairment when events or changes in circumstances indicate the carrying value of an asset may not be recoverable. For long-lived assets other than goodwill that are to be held and used in operations, an impairment is indicated when the estimated total undiscounted cash flow associated with the asset or group of assets is less than carrying value. If impairment exists, an adjustment is made to write the asset down to its fair value, and a loss is recorded as the difference between the carrying value and fair value. Retirement Benefit Plans We account for retirement benefit obligations under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 715, Compensation – Retirement Benefits . For U.S. and certain non-U.S. retirement plans, we derive the discount rates used to measure the present value of benefit obligations using the cash flow matching method. Under this method, we compare the plan’s projected payment obligations by year with the corresponding yields on a Mercer yield curve. Each year’s projected cash flows are then discounted back to their present value at the measurement date and an overall discount rate is determined. The overall discount rate is then rounded to the nearest tenth of a percentage point. We used Mercer’s Above-Mean Curve to determine the discount rates for the year-end benefit obligations and retirement cost of our U.S. retirement plans. We use a local or regional version of the Mercer yield curve in the majority of our non-U.S. locations. In non-U.S. locations where the cash flow matching method is not possible, rates of local high-quality long-term government bonds are used to select the discount rate. We select the expected long-term rate of return assumption for our U.S. pension plan and retiree medical plans using advice from our investment advisor. The selected rate considers plan asset allocation targets, expected overall investment manager performance and long-term historical average compounded rates of return. Benefit plan actuarial gains and losses are recognized in other comprehensive income (loss). Accumulated net benefit plan actuarial gains and losses that exceed 10% of the greater of a plan’s benefit obligation or plan assets at the beginning of the year are amortized into earnings from other comprehensive income (loss) on a straight-line basis. The amortization period for pension plans is the average remaining service period of employees expected to receive benefits under the plans. The amortization period for other retirement plans is primarily the average remaining life expectancy of inactive participants. Income Taxes Deferred tax assets and liabilities are recorded to recognize the expected future tax benefits or costs of events that have been, or will be, reported in different years for financial statement purposes than tax purposes. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which these items are expected to reverse. We recognize tax benefits related to uncertain tax positions if we believe it is more likely than not the benefit will be realized. We review our deferred tax assets to determine if it is more-likely-than-not that they will be realized. If we determine it is not more-likely-than-not that a deferred tax asset will be realized, we record a valuation allowance to reverse the previously recognized tax benefit. Foreign Currency Translation Our consolidated financial statements are reported in U.S. dollars. Our foreign subsidiaries maintain their records primarily in the currency of the country in which they operate. The method of translating local currency financial information into U.S. dollars depends on whether the economy in which our foreign subsidiary operates has been designated as highly inflationary or not. Economies with a three-year cumulative inflation rate of more than 100% are considered highly inflationary. Assets and liabilities of foreign subsidiaries in non-highly inflationary economies are translated into U.S. dollars using rates of exchange at the balance sheet date. Translation adjustments are recorded in other comprehensive income (loss). Revenues and expenses are translated at rates of exchange in effect during the year. Transaction gains and losses are recorded in net income. Foreign subsidiaries that operate in highly inflationary countries use the U.S. dollar as their functional currency. Local currency monetary assets and liabilities are remeasured into U.S. dollars using rates of exchange as of each balance sheet date, with remeasurement adjustments and other transaction gains and losses recognized in earnings. Other than nonmonetary equity securities, nonmonetary assets and liabilities do not fluctuate with changes in local currency exchange rates to the dollar. For nonmonetary equity securities traded in highly inflationary economies, the fair market value of the equity securities are remeasured at the current exchange rates to determine gain or loss to be recorded in net income. Revenues and expenses are translated at rates of exchange in effect during the year. See "Venezuela" and "Argentina" sections below for further information. Venezuela Deconsolidation . Our Venezuelan operations offer transportation and route-based logistics management services for cash and valuables throughout Venezuela. Political and economic conditions in Venezuela, the impact of local laws on our business as well as the currency exchange control regulations and continued reductions in access to U.S. dollars through official currency exchange mechanisms, resulted in an other-than-temporary lack of exchangeability between the Venezuelan bolivar and the U.S. dollar. These conditions restricted the ability of our Venezuelan operations to pay dividends and royalties. It also restricted the ability for our Venezuela business to settle other operating liabilities which significantly increased the risk that this business will no longer be self-sustaining. Our Venezuela operations experienced negative operating cash flows in the first quarter of 2018. As a result, our Venezuela business obtained local currency borrowings in the first and second quarters of 2018 for the first time since the second quarter of 2016. Our Venezuela business will seek additional local financing to support ongoing needs for more bolivars in an environment with significant inflation. It is uncertain as to whether our Venezuela business will be able to obtain the incremental financing in order to operate the business. Banks provide a majority of the business for our Venezuela operations and these banks are limited by law as to how much they can charge their customers in interest. The maximum increase to interest allowable under the law is significantly lower than current and projected inflation rates. Therefore, we do not believe that bank customers will accept increases in our prices that will cover our increase in vendor and labor costs resulting from inflation. Through its restriction by law of interest increases for banks, the Venezuelan government has implemented a defacto price control that affected our business. The currency exchange regulations, combined with other government regulations, such as price controls and strict labor laws, significantly limited our ability to make and execute operational decisions at our Venezuelan subsidiaries. With the May 2018 re-election of the President in Venezuela for an additional six-year term, we expect these conditions to continue for the foreseeable future. As a result of the conditions described above, we concluded that, effective June 30, 2018, we did not meet the accounting criteria for control over our Venezuelan operations and, as a result, we began reporting the results of our investment in our Venezuelan subsidiaries using the cost method of accounting. This change resulted in a pretax charge of $127 million in the second quarter of 2018. The pretax charge included $106 million of foreign currency translation losses and benefit plan adjustments previously included in accumulated other comprehensive loss. It also included the derecognition of the carrying amounts of our Venezuelan operations’ assets and liabilities, including $32 million of assets and $11 million of liabilities, that were no longer reported in our consolidated balance sheet as of June 30, 2018. We determined the fair value of our investment in, and receivables from, our Venezuelan subsidiaries to be insignificant based on our expectations of dividend payments and settlements of such receivables in future periods. For reporting periods beginning after June 30, 2018, we have not included the operating results of our Venezuela operations. In 2018 and 2017, we provided immaterial amounts of financial support to our Venezuela operations. Our exposure to future losses resulting from our Venezuelan business is limited to the extent to which we decide to provide U.S. dollars or make future investments in our Venezuelan subsidiaries. We continue to monitor the situation in Venezuela. Highly Inflationary Accounting . The economy in Venezuela has had significant inflation in the last several years. Prior to deconsolidation as of June 30, 2018, we reported our Venezuelan results using our accounting policy for subsidiaries operating in highly inflationary economies. Results from our Venezuelan operations prior to the June 30, 2018 deconsolidation are included in items not allocated to segments and are excluded from the operating segments. Remeasurement rates during 2016 . In the first quarter of 2016, the Venezuelan government announced that it would replace the SIMADI exchange mechanism with the DICOM exchange mechanism and would allow the DICOM exchange mechanism rate to float freely. From March 31, 2016 through the end of 2016, the rate declined 59% . We received only minimal U.S. dollars through this exchange mechanism. We recognized a $4.8 million pretax remeasurement loss in 2016. However, the after-tax effect in 2016 attributable to noncontrolling interest was income of $2.7 million . Remeasurement rates during 2017. During 2017, the DICOM exchange rate declined 80% . We received only minimal U.S. dollars through this exchange mechanism. In 2017, we recognized a $9.1 million pretax remeasurement loss. The after-tax effect of this loss attributable to noncontrolling interest was $1.0 million . Remeasurement rates during 2018. Prior to deconsolidation as of June 30, 2018, in the first six months of 2018, the DICOM rate declined approximately 97% . We received only minimal U.S. dollars through this exchange mechanism. Prior to deconsolidation as of June 30, 2018, we recognized a $2.2 million pretax remeasurement gain. The after-tax effect of this gain attributable to noncontrolling interest was $2.0 million . Items related to our Venezuelan operations were as follows: • Our investment in our Venezuelan operations on an equity-method basis was $23.1 million at December 31, 2017 . • Our Venezuelan operations had net payables to other Brink's affiliates of $2.7 million at December 31, 2017 . • Our Venezuelan operations had net nonmonetary assets of $23.0 million at December 31, 2017 . • Our bolivar-denominated net monetary liabilities were $2.3 million (including $3.4 million of cash and cash equivalents) at December 31, 2017 . • Accumulated other comprehensive losses attributable to Brink’s shareholders related to our operations in Venezuela were approximately $114.9 million at December 31, 2017 . Argentina We operate in Argentina through wholly owned subsidiaries and a smaller controlled subsidiary (together "Brink's Argentina"). Revenues from Brink's Argentina represented approximately 7% of our consolidated revenues for the year ended December 31, 2018 and 7% and 5% of our consolidated revenues for the years ended December 31, 2017 and 2016 , respectively. The operating environment in Argentina continues to present business challenges, including ongoing devaluation of the Argentine peso and significant inflation. For the year ended December 31, 2017 , the Argentine peso declined by approximately 15% (from 15.9 to 18.6 pesos to the U.S. dollar). For the year ended December 31, 2018 , the Argetine peso declined approximately 50% (from 18.6 to 37.6 pesos to the U.S. dollar). Beginning July 1, 2018, we designated Argentina's economy as highly inflationary for accounting purposes. As a result, we consolidated Brink's Argentina using our accounting policy for subsidiaries operating in highly inflationary economies beginning with the third quarter of 2018. Argentine peso-denominated monetary assets and liabilities are now remeasured at each balance sheet date using the currency exchange rate then in effect, with currency remeasurement gains and losses recognized in earnings. In the second half of 2018, we recognized a $6.2 million pretax remeasurement loss. At December 31, 2018 , Argentina's economy remains highly inflationary for accounting purposes. At December 31, 2018 , we had net monetary assets denominated in Argentine pesos of $24.4 million (including cash of $19.2 million ) and net nonmonetary assets of $148.2 million (including $99.8 million of goodwill). At December 31, 2018 , we had no equity securities denominated in Argentine pesos. Ireland Due to management's decision in the first quarter of 2016 to exit the Republic of Ireland, the prospective impacts of shutting down this operation are included in items not allocated to segments and are excluded from the operating segments effective March 1, 2016. Beginning May 1, 2016, due to management's decision to also exit Northern Ireland, the results of shutting down these operations are treated similarly to the Republic of Ireland. Revenues from both Ireland operations shut down in 2016 were approximately $20 million in 2015. International shipments to and from Ireland will continue to be provided through BGS. Restricted Cash In France, we offer services to certain of our customers where we manage some or all of their cash supply chains. In connection with this offering, we take temporary title to certain customers' cash, which is included as restricted cash in our financial statements due to customer agreement or regulation (see Note 20). Concentration of Credit Risks We routinely assess the financial strength of significant customers and this assessment, combined with the large number and geographic diversity of our customers, limits our concentration of risk with respect to accounts receivable. Financial instruments which potentially subject us to concentrations of credit risks are principally cash and cash equivalents and accounts receivables. Cash and cash equivalents are held by major financial institutions. Use of Estimates In accordance with U.S. generally accepted accounting principles (“GAAP”), we have made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these consolidated financial statements. Actual results could differ materially from those estimates. The most significant estimates are related to goodwill, intangibles and other long-lived assets, pension and other retirement benefit assets and obligations, legal contingencies, deferred tax assets, purchase price allocations and foreign currency translation. Fair-value estimates. We have various financial instruments included in our financial statements. Financial instruments are carried in our financial statements at either cost or fair value. We estimate fair value of assets using the following hierarchy using the highest level possible: Level 1: Quoted prices for identical assets or liabilities in active markets. Level 2: Quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are directly or indirectly observable, or inputs that are derived principally from, or corroborated by, observable market data by correlation or other means. Level 3: Unobservable inputs that reflect estimates and assumptions. New Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue From Contracts with Customers. Under this standard, an entity recognizes an amount of revenue to which it expects to be entitled when the transfer of goods or services to customers occurs. The standard requires expanded disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. We adopted this standard effective January 1, 2018 using the modified retrospective method and recognized a cumulative-effect adjustment increasing retained earnings by $1.5 million . The most significant effects of the standard for us are associated with variable consideration and capitalization of costs to obtain contracts, such as sales commissions. Previously, we recognized the impact of pricing changes in the period they became fixed and determinable, and we expensed sales commissions and other costs to obtain contracts as they were incurred. We do not expect a material impact on our future consolidated statements of operations or consolidated balance sheets as a result of implementing this standard. However, adoption of the standard resulted in expanded disclosures related to revenue (see Note 2). The FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, in January 2016. This standard changes the accounting related to the classification and measurement of certain equity investments. Equity investments with readily determinable fair values must be measured at fair value. All changes in fair value will be recognized in net income as opposed to other comprehensive income. We adopted ASU 2016-01 effective January 1, 2018 and recognized a cumulative-effect adjustment increasing retained earnings by $1.1 million . In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting , which simplifies how certain features related to share-based payments are accounted for and presented in the financial statements. We elected to early adopt this ASU in the fourth quarter of 2016 and, per the requirements of the pronouncement, we applied the amendments to the beginning of 2016. Under ASU 2016-09, accounting changes adopted using the modified retrospective method were calculated as of the beginning of 2016 and reported as a cumulative-effect adjustment. As a result, we recognized a $0.2 million cumulative-effect adjustment to January 1, 2016 retained earnings for previously unrecognized excess tax benefits. We elected to continue our previous accounting policy of estimating forfeitures and, therefore, we did not recognize any cumulative-effect adjustment related to forfeitures. ASU 2016-09 requires that accounting changes adopted using the prospective method should be reported in the applicable interim periods of 2016. We did not have any material changes to previously reported interim financial information in 2016 as it relates to the recognition of excess tax benefits in the statements of operations or the classification of excess tax benefits in the statements of cash flows. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory , which changes the timing of when certain intercompany transactions are recognized within the provision for income taxes. We adopted ASU 2016-16 effective January 1, 2018 using the modified retrospective method and we recognized a cumulative-effect adjustment increasing retained earnings by $0.7 million . The FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash , in November 2016. This standard requires entities to include restricted cash and restricted cash equivalent balances with cash and cash equivalent balances in the statements of cash flows. Inclusion of restricted cash impacts our operating activities, financing activities and the effect of exchange rate changes on cash. We adopted ASU 2016-18 effective January 1, 2018 using the retrospective transition method. The adoption of this ASU changed previously reported amounts in the consolidated statements of cash flows. Net cash provided by operating activities increased $44.3 million , net cash provided by financing activities increased $1.5 million and the effect of exchange rate changes on cash decreased favorably by $11.3 million as compared to previously reported amounts for the year ended December 31, 2017. Net cash provided by operating activities increased $22.8 million , net cash used by financing activities decreased $19.9 million and the effect of exchange rate changes on cash increased unfavorably by $3.6 million as compared to previously reported amounts for the year ended December 31, 2016. In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , which requires an entity to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. We elected to early adopt this ASU in the first quarter of 2017 using the retrospective transition method for the periods presented. As a result, the consolidated statements of operations were updated to reflect this guidance. The early adoption of this ASU had no impact on the previously reported income from continuing operations or net income for the prior year periods. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which will require the recognition of right-of-use assets and lease liabilities by lessees for certain leases classified as operating leases under current accounting guidance and will also require expanded disclosures regarding leasing activities. The accounting for capital leases remains substantially unchanged. ASU 2016-02 will be effective January 1, 2019 and we have elected to adopt the new standard at the adoption date through a cumulative-effect adjustment to the opening balance of retained earnings. Under this approach, we will continue to report comparative periods presented in the period of adoption under ASC 840. We have elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allows us to carry forward the historical lease classification. We also made an accounting policy election to keep leases with an initial term of 12 months or less off of the balance sheet. We will recognize those lease payments in the consolidated statements of operations on a straight-line basis over the lease term. In preparation for adoption of the standard, we are implementing internal controls and key system functionality to enable the preparation of financial information. We are still in the process of finalizing our opening balance sheet adjustment, but we estimate adoption of the standard will result in recognition of additional lease assets and lease liabilities in the range of $260 million and $360 million as of January 1, 2019. We do not believe the standard will materially affect our consolidated statements of operations or our consolidated statements of cash flows. The standard will have no impact on our debt-covenant compliance under our current agreements. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments , which significantly changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life. ASU 2016-13 is effective January 1, 2020, with early adoption permitted January 1, 2019. We are assessing the potential impact of this new standard on financial reporting. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other: Simplifying the Test for Goodwill Impairment , which requires an entity to no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. The guidance is effective January 1, 2020 with early adoption permitted. We are currently evaluating the impact of this guidance, including transition elections and required disclosures, on our financial statements and the timing of adoption. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting f

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Performance Obligations We provide various services to meet the needs of our customers and we group these service offerings into three broad categories: Core Services, High-Value Services and Other Security Services. Core Services CIT and ATM services are core services we provide to customers throughout the world. We charge customers per service performed or based on the value of goods transported. CIT services generally involve the secure transportation of cash, securities and other valuables between businesses, financial institutions and central banks. ATM services are generally composed of management services, including cash replenishment and forecasting, remote monitoring, transaction processing, installation and maintenance. High-Value Services Our high-value services leverage our brand, global infrastructure and core services and include cash management services, global services and payment services. We offer a variety of cash management services such as currency and coin counting and sorting, deposit preparation and reconciliation, and safe device installation and servicing (including our CompuSafe ® service). Our global services business provides secure ground, sea and air transportation and storage of highly-valued commodities including diamonds, jewelry, precious metals and other valuables. We also provide payment services which include bill payment and processing services on behalf of utility companies and other billers plus general purpose reloadable prepaid cards and payroll cards. Other Security Services Our other security services feature the protection of airports, offices, warehouses, stores and public venues in Europe and Brazil. For performance obligations related to the services described above, we generally satisfy our obligations as each action to provide the service to the customer occurs. Because the customers simultaneously receive and consume the benefits from our services, these performance obligations are deemed to be satisfied over time. We use an output method, units of service provided, to recognize revenue because that is the best method to represent the transfer of our services to the customer at the agreed upon rate for each action. Although not as significant as our service offerings, we also sell goods to customers from time to time, such as safe devices. In those transactions, we satisfy our performance obligation at a point in time. We recognize revenue when the goods are delivered to the customer as that is the point in time that best represents when control has transferred to the customer. Our contracts with customers describe the services we can provide along with the fees for each action to provide the service. We typically send invoices to customers for all of the services we have provided within a monthly period and payments are generally due within 30 to 60 days of the invoice date. Although our customer contracts specify the fees for each action to provide service, the majority of the services stated in our contracts do not have a defined quantity over the contract term. Accordingly, the transaction price is considered variable as there is an unknown volume of services that will be rendered over the course of the contract. We recognize revenue for these services in the period in which they are provided to the customer based on the contractual rate at which we have the right to invoice the customer for each action. Some of our contracts with customers contain clauses that define the level of service that the customer will receive. The service level agreements (“SLA”) within those contracts contain specific calculations to determine whether the appropriate level of service has been met within a specific period, which is typically a month. We estimate SLA penalties and recognize the amounts as a reduction to revenue. Taxes collected from customers and remitted to governmental authorities are not included in revenues in the consolidated statements of operations. Revenue Disaggregated by Reportable Segment and Type of Service (In millions) Core Services High-Value Services Other Security Services Total Twelve months ended December 31, 2018 Reportable Segments: North America $ 895.1 571.2 — 1,466.3 South America 449.8 465.1 12.0 926.9 Rest of World 357.3 512.0 175.0 1,044.3 Total reportable segments 1,702.2 1,548.3 187.0 3,437.5 Not Allocated to Segments: Venezuela (a) 18.4 33.0 — 51.4 Total $ 1,720.6 1,581.3 187.0 3,488.9 (a) Represents revenues from our Venezuela operations prior to June 30, 2018 deconsolidation. See Note 1 for details. The majority of our revenues from contracts with customers are earned by providing services and these performance obligations are satisfied over time. Smaller amounts of revenues are earned from selling goods, such as safes, to customers where the performance obligations are satisfied at a point in time. Certain of our high-value services involve the leasing of assets, such as safes, to our customers along with the regular servicing of those safe devices. Revenues related to the leasing of these assets are recognized in accordance with ASC 840, Leases , but are included in the above table as the amounts are a small percentage of overall revenues. Contract Balances Contract Asset Although payment terms and conditions can vary, for the majority of our customer contracts, we invoice for all of the services provided to the customer within a monthly period. For certain customer contracts, the timing of our performance may precede our right to invoice the customer for the total transaction price. For example, Brink's affiliates in certain countries, primarily in South America, negotiate annual price adjustments with certain customers and, once the price increases are finalized, the pricing changes are made retroactive to services provided in earlier periods. These retroactive pricing adjustments are estimated and recognized as revenue with a corresponding contract asset in the same period in which the related services are performed. As the estimate of the ultimate transaction price changes, we recognize a cumulative catch-up adjustment for the change in estimate. Contract Liability For other customer contracts, we may obtain the right to payment or receive customer payments prior to performing the related services under the contract. When the right to customer payments or receipt of payments precedes our performance, we recognize a contract liability. The opening and closing balances of receivables, contract assets and contract liabilities related to contracts with customers are as follows: (In millions) Receivables Contract Asset Contract Liability Opening (January 1, 2018) $ 642.3 0.4 5.6 Closing (December 31, 2018) 599.5 1.8 2.5 Increase (decrease) $ (42.8 ) 1.4 (3.1 ) The amount of revenue recognized in 2018 that was included in the January 1, 2018 contract liability balance was $5.6 million . This revenue consists of services provided to customers who had prepaid for those services prior to the current year. We also recognized revenue of $0.6 million in 2018 from performance obligations satisfied in the prior year. This amount is a result of changes in the transaction price of our contracts with customers. Contract Costs Sales commissions directly related to obtaining new contracts with customers qualify for capitalization. These capitalized costs are amortized to expense ratably over the term of the contracts. At December 31, 2018 , the net capitalized costs to obtain contracts was $1.8 million , which is included in other assets on the consolidated balance sheet. Amortization expense in 2018 was not significant and there were no impairment losses recognized related to these contract costs in 2018. Practical Expedients For the majority of our contracts with customers, we invoice a fixed amount for each unit of service we have provided. These contracts provide us with the right to invoice for an amount or rate that corresponds to the value we have delivered to our customers. The volume of services that will be provided to customers over the term is not known at inception of these contracts. Therefore, while the rate per unit of service is known, the transaction price itself is variable. For this reason, we recognize revenue from these contracts equal to the amount for which we have the contractual right to invoice the customers. Because we are not required to estimate variable consideration related to the transaction price in order to recognize revenue, we are also not required to estimate the variable consideration to provide certain disclosures. As a result, we have elected to use the optional exemption related to the disclosure of transaction prices, amounts allocated to remaining performance obligations and the future periods in which revenue will be recognized, sometimes referred to as backlog. We have also elected to use the practical expedient for financing components related to our contract liabilities. We do not recognize interest expense on contracts for which the period between our receipt of customer payments and our service to the customer is one year or less. Impact on Reported Amounts We adopted ASU 2014-09, Revenue From Contracts with Customers , effective January 1, 2018 using the modified retrospective method. As a result, we recognized a cumulative-effect adjustment to January 1, 2018 retained earnings. Comparative prior year period amounts are reported in accordance with previous accounting standards. The adoption of the new revenue recognition standard impacted our reported amounts in 2018 as follows: (In millions) As reported Impact of New Revenue Recognition Standard Pro Forma under Old Revenue Recognition Standard Twelve months ended December 31, 2018 Statement of Operations Revenues $ 3,488.9 4.0 3,484.9 Operating profit 274.7 2.0 272.7 Net income (loss) attributable to Brink's (33.3 ) 1.4 (34.7 ) As of December 31, 2018 Balance Sheet Prepaid expenses and other assets $ 127.5 1.8 125.7 Other assets 186.1 1.8 184.3 Retained earnings 429.1 2.9 426.2

Segment Reporting [Abstract]
Segment information	Segment Information We identify our operating segments based on how our chief operating decision maker (“CODM”) allocates resources, assesses performance and makes decisions. Our CODM is our President and Chief Executive Officer. Our CODM evaluates performance and allocates resources to each operating segment based on a profit or loss measure which, at the reportable segment level, excludes the following: • Corporate expenses - former non-segment and regional management costs, currency transaction gains and losses, adjustments to reconcile segment accounting policies to U.S. GAAP, and costs related to global initiatives • Other items not allocated to segments - certain significant items such as reorganization and restructuring actions that are evaluated on an individual basis by management and are not considered part of the ongoing activities of the business are excluded from segment results. Prior to deconsolidation (see Note 1), results from Venezuela operations were also excluded from our segment results due to the Venezuelan government's restrictions that have prevented us from repatriating funds. We also exclude certain costs, gains and losses related to acquisitions and dispositions of assets and of businesses. Beginning in the third quarter of 2018, we began to consolidate Brink's Argentina using our accounting policy for subsidiaries operating in highly inflationary economies. We have excluded from our segment results the impact of highly inflationary accounting in Argentina, including currency remeasurement losses. Incremental third party costs incurred related to the mitigation of material weaknesses and the implementation and adoption of ASU 2016-02, the new lease accounting standard effective for us January 1, 2019, are also excluded from segment results. We currently serve customers in more than 100 countries, including 41 countries where we operate subsidiaries. We have the following three reportable segments: • North America • South America • Rest of World.

Retirement Benefits [Abstract]
Retirement Benefits	Retirement Benefits Defined-benefit Pension Plans Summary We have various defined-benefit pension plans covering eligible current and former employees. Benefits under most plans are based on salary and years of service. There are limits to the amount of benefits which can be paid to participants from a U.S. qualified pension plan. We maintain a nonqualified U.S. plan to pay benefits for those eligible current and former employees in the U.S. whose benefits exceed the regulatory limits. Pension benefits provided to eligible U.S. employees were frozen on December 31, 2005.

Other Changes in Plan Assets and Benefit Recognized in Other Comprehensive Income (Loss) (In millions) U.S. Plans Non-U.S. Plans Total Years Ended December 31, 2018 2017 2018 2017 2018 2017 Benefit plan net actuarial losses recognized in accumulated other comprehensive income (loss): Beginning of year $ (308.9 ) (320.9 ) (82.9 ) (82.9 ) (391.8 ) (403.8 ) Net actuarial gains (losses) arising during the year (24.8 ) (14.6 ) (2.4 ) (1.2 ) (27.2 ) (15.8 ) Reclassification adjustment for amortization of prior actuarial losses included in net income (loss) 27.7 26.6 18.7 7.3 46.4 33.9 Foreign currency exchange effects — — 4.6 (6.1 ) 4.6 (6.1 ) End of year $ (306.0 ) (308.9 ) (62.0 ) (82.9 ) (368.0 ) (391.8 ) Benefit plan prior service cost recognized in accumulated other comprehensive income (loss): Beginning of year $ — — (8.3 ) (9.2 ) (8.3 ) (9.2 ) Reclassification adjustment for amortization of prior service cost included in net income (loss) — — 7.1 1.1 7.1 1.1 Foreign currency exchange effects — — — (0.2 ) — (0.2 ) End of year $ — — (1.2 ) (8.3 ) (1.2 ) (8.3 ) U.S. Plans The net actuarial losses of $24.8 million in 2018 and $14.6 million in 2017 were mainly driven by changes in the primary U.S. pension plan. The 2018 primary U.S. pension plan's net actuarial losses arose from lower actual return on assets than expected ( $96 million ), largely offset by a higher discount rate at the end of the year ( $65 million ) and the impact from updating the mortality projection table ( $4 million ). The 2017 primary U.S. pension plan's net actuarial losses arose from lower discount rates at the end of the year ( $60 million ), largely offset by actual return on assets being higher than expected ( $44 million ) and census data updates ( $3 million ). Non-U.S. Plans The net actuarial losses of $2.4 million in 2018 were primarily due to actual return on assets being lower than expected, partially offset by higher discount rates at the end of the year. The net actuarial losses of $1.2 million in 2017 were primarily due to the lower discount rates at the end of the year, largely offset by actual return on assets being higher than expected. Information Comparing Plan Assets to Plan Obligations Information comparing plan assets to plan obligations as of December 31, 2018 and 2017 are aggregated below. The accumulated benefit obligation (“ABO”) differs from the PBO in that the ABO is based on the benefit earned through the date noted. The PBO includes assumptions about future compensation levels for plans that have not been frozen. The total ABO for our U.S. pension plans was $801.9 million in 2018 and $890.3 million in 2017 . The total ABO for our Non-U.S. pension plans was $233.9 million in 2018 and $264.8 million in 2017 .

The U.S. plan benefits are frozen and will not increase due to future salary increases. Mortality Tables for our U.S. Retirement Benefits We use the Mercer modified RP-2014 base table and the Mercer modified MP-2018 projection scale, with a Blue Collar adjustment factor for the majority of our U.S. retirement plans and a White Collar adjustment factor for our nonqualified U.S. pension plan. Estimated Future Cash Flows Estimated Future Contributions from the Company into Plan Assets Our policy is to fund at least the minimum actuarially determined amounts required by applicable regulations. We do not expect to make contributions to our primary U.S. pension plan in 2019 . We expect to contribute $10.4 million to our non-U.S. pension plans and $1.3 million to our nonqualified U.S. pension plan in 2019 . Estimated Future Benefit Payments from Plan Assets to Beneficiaries Projected benefit payments of the plans in the next 10 years using assumptions in effect at December 31, 2018 , are as follows: (In millions) U.S. Plans Non-U.S. Plans Total 2019 $ 52.3 10.4 62.7 2020 51.9 10.4 62.3 2021 51.7 11.3 63.0 2022 51.6 11.9 63.5 2023 51.7 12.8 64.5 2024 through 2028 255.4 101.4 356.8 Retirement Benefits Other than Pensions Summary We provide retirement healthcare benefits for eligible current and former U.S., Canadian, and Brazilian employees. Retirement benefits related to our former U.S. coal operation include medical benefits provided by the Pittston Coal Group Companies Employee Benefit Plan for UMWA Represented Employees (the “UMWA plans”) as well as costs related to black lung obligations.

The net actuarial losses of $66.3 million in 2017 arose primarily as a result of claims experience impact ( $38 million ), a lower discount rate impact ( $25 million ) and excise tax update impact ( $17 million ), partially offset by return on assets being higher than expected ( $18 million ). Black Lung and Other Plans We recognized net actuarial losses of $6.4 million in 2018. This was primarily due to updates to the black lung census data that increased the obligation by $9 million , partially offset by a higher discount rate compared to the prior period of $4 million . We recognized net actuarial losses of $14.9 million in 2017. This was primarily related to the black lung census data and claims experience updates. Assumptions See Mortality Tables for our U.S. Retirement Benefits on page 84 for a description of the mortality assumptions. The APBO for each of the plans was determined using the unit credit method and assumed rates as follows: 2018 2017 2016 Weighted-average discount rate: Postretirement cost: UMWA plans 3.6 % 4.1 % 4.4 % Black lung 3.5 % 3.9 % 4.2 % Weighted-average 3.7 % 4.2 % 4.4 % Benefit obligation at year end: UMWA plans 4.3 % 3.6 % 4.1 % Black lung 4.2 % 3.5 % 3.9 % Weighted-average 4.4 % 3.7 % 4.2 % Expected return on assets 8.00 % 8.25 % 8.25 % Healthcare Cost Trend Rates For UMWA plans, the assumed healthcare cost trend rate used to compute the 2018 APBO is 6.5% for 2019 , declining to 5.0% in 2026 and thereafter (in 2017 : 6.5% for 2018 declining to 5.0% in 2024 and thereafter). For the black lung obligation, the assumed healthcare cost trend rate used to compute the 2018 APBO was 5.0% . Other plans in the U.S. provide for fixed-dollar value coverage for eligible participants and, accordingly, are not adjusted for inflation. For the Canadian plan, the assumed healthcare cost trend rate used to compute the 2018 APBO is 6.5% for 2019 , declining to 5.0% in 2026 . For the Brazilian plan, the assumed healthcare cost trend rate used to compute the 2018 APBO is 3.3% . We provide healthcare benefits to our UMWA retirees who are eligible for the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the “Medicare Act”) subsidy reimbursement under an employer group waiver plan (“EGWP”). Under this arrangement, a government approved health insurance provider receives the Medicare Act subsidy reimbursement on our behalf and passes these savings to us. Additionally, by providing healthcare benefits under an EGWP, we are able to benefit from the mandatory 50% discount that pharmaceutical companies must provide for Medicare Act-eligible prescription drugs. Excise Tax on Administrators by Patient Protection and Affordable Care Act of 2010 A 40% excise tax on third-party benefit plan administrators by the Patient Protection and Affordable Care Act will be imposed on high-cost health plans (“Cadillac plans”). The Tax Reform Act delayed the effective date of the excise tax on Cadillac plans to 2022. We are currently unable to reduce the benefit levels of our UMWA medical plans to avoid this excise tax because these benefit levels are required by the Coal Industry Retiree Health Benefit Act of 1992. We have assumed that the cost of the excise tax paid by administrators will be passed through to us in the form of higher premiums or higher claims administration fees, increasing our obligations. Our plan obligations at December 31, 2018 , include $30.5 million related to this tax ( $34.5 million at December 31, 2017 ). Cash Flows Estimated Contributions from the Company to Plan Assets Based on the funded status and assumptions at December 31, 2018 , we expect the Company to contribute $7.8 million in cash to the plans to pay 2019 beneficiary payments for black lung and other plans. We do not expect to contribute cash to our UMWA plans in 2019 since we believe these plans have sufficient amounts held in trust to pay for beneficiary payments until 2025 based on actuarial assumptions. Our UMWA plans are not covered by ERISA or other funding laws or regulations that require these plans to meet funding ratios. Estimated Future Benefit Payments from Plan Assets to Beneficiaries Projected benefit payments of the plans in the next 10 years using assumptions in effect at December 31, 2018 , are as follows: (In millions) UMWA Plans Black Lung and Other Plans Total 2019 $ 33.5 7.8 41.3 2020 33.6 7.3 40.9 2021 33.6 6.8 40.4 2022 34.2 6.4 40.6 2023 34.0 5.9 39.9 2024 through 2028 161.8 24.4 186.2 Retirement Plan Assets U.S. Plans December 31, 2018 December 31, 2017 (In millions, except for percentages) Fair Value Level Total Fair Value % Actual Allocation % Target Allocation Total Fair Value % Actual Allocation % Target Allocation U.S. Pension Plans Cash, cash equivalents and receivables $ 4.1 — — 4.6 1 — Equity securities: U.S. large-cap (a) 1 79.1 12 12 88.1 11 12 U.S. small/mid-cap (a) 1 28.5 4 5 36.4 5 5 International (a) 1 102.3 15 15 111.5 14 15 Emerging markets (b) 1 9.9 1 2 15.0 2 2 Dynamic asset allocation (c) 1 22.4 3 4 29.8 4 4 Fixed-income securities: Long duration - mutual fund (d) 1 260.3 48 48 304.2 49 48 Long duration - Treasury strips (d) 2 68.6 74.5 High yield (e) 1 10.9 2 2 14.8 2 2 Emerging markets (f) 1 10.4 1 2 15.2 2 2 Other types of investments: Core property (g) (l) 44.7 7 5 41.0 5 5 Structured credit (h) (l) 45.4 7 5 42.1 5 5 Total $ 686.6 100 100 777.2 100 100 UMWA Plans Equity securities: U.S. large-cap (a) 1 $ 29.1 16 19 40.3 18 19 U.S. small/mid-cap (a) 1 12.0 7 8 16.8 8 8 International (a) 1 35.8 20 24 50.6 23 24 Emerging markets (b) 1 6.2 3 4 8.6 4 4 Dynamic asset allocation (c) 1 10.8 6 7 15.2 7 7 Fixed-income securities: High yield (e) 1 3.3 2 2 4.3 2 2 Emerging markets (f) 1 6.1 3 4 8.7 4 4 Multi asset real return (i) 1 7.6 4 5 10.8 5 5 Other types of investments: Core property (g) (l) 25.2 14 10 23.1 11 10 Structured credit (h) (l) 13.4 7 5 12.4 6 5 Global private equity (j) (l) 15.5 9 7 11.8 5 7 Energy debt (k) (l) 16.7 9 5 16.6 7 5 Total $ 181.7 100 100 219.2 100 100 (a) These categories include a passively managed U.S. large-cap equity mutual fund and actively managed U.S. small/mid-cap equity and Non-U.S. mutual funds that track various indices such as the S&P 500 Index, the Russell 2500 Index and the MSCI All Country World Ex-U.S. Index. (b) This category represents an actively managed mutual fund that invests primarily in equity securities of emerging market issuers. Emerging market countries are those countries that are characterized as developing or emerging by any of the World Bank, the United Nations, the International Finance Corporation, or the European Bank for Reconstruction and Development or included in an emerging markets index by a recognized index provider. (c) This category represents an actively managed mutual fund that seeks to generate total return over time by selecting investments from among a broad range of asset classes. The fund’s allocations among asset classes may be adjusted over short periods and can vary from multiple to a single asset class. (d) This category represents actively managed mutual funds that seek to duplicate the risk and return characteristics of a long-term fixed-income security portfolio with approximate duration of 10 to 15 years and longer by using a long duration bond portfolio. This category also includes Treasury future contracts and zero -coupon securities created by the U.S. Treasury. (e) This category represents an actively managed mutual fund that invests primarily in fixed-income securities rated below investment grade, including corporate bonds and debentures, convertible and preferred securities and zero-coupon obligations. The fund’s average weighted maturity may vary and will generally not exceed ten years. (f) This category represents an actively managed mutual fund that invests primarily in U.S. dollar-denominated debt securities of government, government-related and corporate issuers in emerging market countries, as well as entities organized to restructure the outstanding debt of such issuers. (g) This category represents an actively managed real estate fund of funds that seeks both current income and long-term capital appreciation through investing in underlying funds that acquire, manage, and dispose of commercial real estate properties. These properties are high-quality, low-leveraged, income-generating office, industrial, retail, and multi-family properties, generally fully-leased to creditworthy companies and governmental entities. (h) This category invests primarily in a diversified portfolio comprised primarily of collateralized loan obligations and other structured credit investments backed primarily by bank loans. (i) This category represents an actively managed mutual fund that invests primarily in fixed income and equity securities and commodity linked instruments. The category seeks total returns that exceed the rate of inflation over a full market cycle regardless of market conditions. (j) This category will offer exposure to a diversified pool of global private assets fund investments. Further, the category will seek to shorten the duration of the typical private assets fund of funds through a dedicated focus on secondary strategies (i.e. funds whose investment strategy is to purchase interests in other private market investments/funds as a way to provide the original investors liquidity prior to the end of those investments’/funds’ contracted end date), income-producing investment strategies (e.g. debt, real estate, and to a lesser extent, real assets), and underlying funds whose stated life is five to seven years, as opposed to the more typical 10 -year life of private assets funds. (k) This category invests in credit securities of commodity oriented companies affected by the dislocation in the commodity markets with the investment objective of producing an equity like return with less downside risk than equity or commodity investments. (l) In accordance with Subtopic 820-10, certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the consolidated balance sheets. Assets of our U.S. plans are invested with an objective of maximizing the total return, taking into consideration the liabilities of the plan, and minimizing the risks that could create the need for excessive contributions. Plan assets are invested primarily using actively managed accounts with asset allocation targets listed in the tables above. Our policy does not permit the purchase of Brink’s common stock if immediately after any such purchase the aggregate fair market value of the plan assets invested in Brink’s common stock exceeds 10% of the aggregate fair market value of the assets of the plan, except as permitted by an exemption under ERISA. The plans rebalance their assets on a quarterly basis if actual allocations of assets are outside predetermined ranges. Among other factors, the performance of asset groups and investment managers will affect the long-term rate of return. The UMWA plans re-locked their energy debt investment for another three years, which now expires in 2022. The global private equity investment cannot be redeemed due to the nature of the underlying investments. As the global private equity investment matures and becomes fully invested, liquidating distributions will be provided back to investors. We expect to receive liquidating distributions over the stated life of the underlying investments. We have $8 million in unfunded commitments related to the global private equity investment. Most of the investments of our U.S. retirement plans can be redeemed daily. The structured credit investments can be redeemed quarterly with 65 days’ notice. The core property fund investment can be redeemed quarterly with 95 days’ notice. The energy debt investment can be redeemed semi-annually with 95 days' notice. We believe all plans have sufficient liquidity to meet the needs of the plans' beneficiaries in all market scenarios.

(d) This category consists of a diversified portfolio of debt securities issued by governments, financial institutions, companies or other entities domiciled in emerging market countries. (e) This category is designed to achieve a return consistent with holding longer term debt instruments. This category invests in interest rate and inflation derivatives, government-issued bonds, real-return bonds, and futures contracts. Asset allocation strategies for our non-U.S. plans are designed to accumulate a diversified portfolio among markets and asset classes in order to reduce market risk and increase the likelihood that pension assets are available to pay benefits as they are due. Assets of non-U.S. pension plans are invested primarily using actively managed accounts. The weighted-average asset allocation targets are listed in the table above, and reflect limitations on types of investments held and allocations among assets classes, as required by local regulation or market practice of the country where the assets are invested. Most of the investments of our non-U.S. retirement plans can be redeemed at least monthly, except for a portion of “Other” in the above table, which can be redeemed quarterly.

Income Taxes	Dec. 31, 2018
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Reform Act”) was enacted into law. The Tax Reform Act includes a reduction in the federal tax rate for corporations from 35% to 21% as of January 1, 2018, a one-time transition tax on the cumulative undistributed earnings of foreign subsidiaries as of December 31, 2017, a repeal of the corporate alternative minimum tax, and more extensive limitations on deductibility of performance-based compensation for named executive officers. Other provisions effective as of January 1, 2018, which could materially impact the Company in the near-term, include the creation of a new U.S. minimum tax on foreign earnings called the Global Intangible Low-Taxed Income (“GILTI”) and limitations on the deductibility of interest expense. Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Reform Act, the Company recorded provisional amounts as of December 31, 2017, in accordance with Staff Accounting Bulletin No. 118 ("SAB 118"). We recorded a provisional one-time non-cash charge of $92 million in the fourth quarter of 2017 to remeasure the deferred tax assets for the new rate and for other legislative changes. In the fourth quarter of 2018, we recorded a benefit of $2.3 million to reverse a component of the provisional one-time non-cash charge as a result of guidance issued by the U.S. authorities. We filed our 2017 U.S. federal income tax return in October 2018, which did not reflect a U.S. federal current tax liability for the transition tax due to our high-tax foreign income, but we recorded an incremental $1.3 million of foreign tax credits, offset with a full valuation allowance in the fourth quarter of 2018 which was in addition to the provisional $31.1 million foreign tax credit offset with a full valuation allowance related to the transition tax recorded in the fourth quarter of 2017. We did not record a current state tax liability related to the transition tax in accordance with the interpretation of existing state laws and the provisional estimates in the fourth quarter of 2017, but we recorded the state impact of the transition tax of $0.2 million when we filed our tax returns in the fourth quarter of 2018. We adopted an accounting policy related to the provision of deferred taxes related to GILTI and determined that we would not record deferred taxes with respect to GILTI, but would instead treat GILTI as a current period cost. We did not change our assertion on the determination of which subsidiaries that we consider to be permanently invested and for which we do not expect to repatriate to the U.S. as a result of the Tax Reform Act. The accounting for the Tax Reform Act was completed in the fourth quarter of 2018 in accordance with SAB 118.

The U.S. foreign tax credits and other U.S. tax credits have a valuation allowance. Valuation Allowances Valuation allowances relate to deferred tax assets for certain federal credit carryforwards, certain state and non-U.S. jurisdictions. Based on our analysis of positive and negative evidence including historical and expected future taxable earnings, and a consideration of available tax-planning strategies, we believe it is more-likely-than-not that we will realize the benefit of the existing deferred tax assets, net of valuation allowances, at December 31, 2018 .

Amounts are recognized in income from continuing operations. (b) In 2016, we recognized $2.5 million in retained earnings as a result of the early adoption of ASU 2016-09. Net Operating Losses The gross amount of the net operating loss carryforwards as of December 31, 2018 , was $362.7 million . The tax benefit of net operating loss carryforwards, before valuation allowances, as of December 31, 2018 , was $42.0 million , and expires as follows: (In millions) Federal State Foreign Total Years of expiration 2019-2023 $ — — 5.5 5.5 2024-2028 — 0.6 3.2 3.8 2029 and thereafter — 13.9 0.4 14.3 Unlimited — — 18.4 18.4 $ — 14.5 27.5 42.0 Uncertain Tax Positions A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: Years Ended December 31, (In millions) 2018 2017 2016 Uncertain tax positions: Beginning of year $ 10.4 6.4 6.9 Increases related to prior-year tax positions 0.3 0.1 0.6 Decreases related to prior-year tax positions — (0.5 ) (0.4 ) Increases related to current-year tax positions 1.3 1.4 1.2 Increases related to acquisitions — 4.2 — Decreases related to acquisitions (0.2 ) — — Settlements (0.4 ) (0.1 ) (0.8 ) Effect of the expiration of statutes of limitation (1.1 ) (0.8 ) (0.8 ) Foreign currency exchange effects (0.8 ) (0.3 ) (0.3 ) End of year $ 9.5 10.4 6.4 Included in the balance of unrecognized tax benefits at December 31, 2018 , are potential benefits of approximately $9.0 million that, if recognized, will reduce the effective tax rate on income from continuing operations. We recognize accrued interest and penalties related to unrecognized tax benefits in provision (benefit) for income taxes. We reverse interest and penalties accruals when a statute of limitation lapses or when we otherwise conclude the amounts should not be accrued. The impact of interest and penalties on the 2018 tax provision was not significant compared to the net increase (reversal) included in provision (benefit) for income taxes of ($0.3) million in 2017 and $0.1 million in 2016 . We had accrued interest and penalties of $1.8 million at December 31, 2018 , and $0.8 million at December 31, 2017 . We file income tax returns in the U.S. federal and various state and foreign jurisdictions. With a few exceptions, as of December 31, 2018 , we were no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2015 . Additionally, due to statute of limitations expirations and audit settlements, it is reasonably possible that approximately $1.4 million of currently remaining unrecognized tax positions may be recognized by the end of 2019.

Business Combinations [Abstract]
Acquisitions and Dispositions	Acquisitions and Dispositions In 2018, we acquired one business operation and additionally acquired a controlling interest in a second business operation. In 2017, we acquired six business operations. We accounted for these acquisitions as business combinations using the acquisition method. Under the acquisition method of accounting, assets acquired and liabilities assumed from these operations are recorded at fair value on the date of acquisition. The consolidated statements of operations include the results of operations for each acquired entity from the date of acquisition. Dunbar Armored, Inc. ("Dunbar") U.S. cash management business On August 13, 2018 , we acquired 100% of the shares of Dunbar for approximately $547 million , subject to a working capital adjustment. The Dunbar business is being integrated with our existing Brink's U.S. operations. This acquisition is expected to expand our customer base in the U.S. as a result of Dunbar's focus on small-to-medium sized retailers and financial institutions. Dunbar has approximately 5,400 employees, 78 branches and over 1,600 armored vehicles across its operations. We have provisionally estimated fair values for the assets purchased, liabilities assumed and purchase consideration as of the date of the acquisition in the following table. The determination of estimated fair value required management to make significant estimates and assumptions. The amounts reported are considered provisional as we are completing the valuations that are required to allocate the purchase price. As a result, the allocation of the provisional purchase price may change in the future. Our fair value estimates of acquisition date intangible assets decreased approximately $20 million , acquisition date goodwill increased approximately $24 million , acquisition date other noncurrent assets increased approximately $11 million and acquisition date noncurrent liabilities increased approximately $13 million as compared to our initial estimates in the period of acquisition. There have been no other significant changes to our fair value estimates of the net assets acquired for the Dunbar acquisition. (In millions) Estimated Fair Value at Acquisition Date Fair value of purchase consideration Cash paid through December 31, 2018 $ 546.8 Fair value of purchase consideration $ 546.8 Fair value of net assets acquired Cash $ 25.8 Accounts receivable 31.9 Other current assets 11.7 Property and equipment, net 57.0 Intangible assets (a) 162.0 Goodwill (b) 307.1 Other noncurrent assets 21.1 Current liabilities (29.7 ) Noncurrent liabilities (40.1 ) Fair value of net assets acquired $ 546.8 (a) Intangible assets are composed of customer relationships ( $148 million fair value and 15 year amortization period) and rights related to the trade name ( $14 million fair value and 8 year amortization period). Final allocation will be determined once the valuation is complete. (b) Consists of intangible assets that do not qualify for separate recognition, combined with synergies expected from integrating Dunbar’s operations with our existing Brink’s U.S. operations. All of the goodwill has been assigned to the U.S. reporting unit and is expected to be deductible for tax purposes. Maco Transportadora de Caudales S.A. (“Maco Transportadora”) Argentine CIT and money processing business On July 18, 2017 , we acquired 100% of the shares of Maco Transportadora for approximately $206 million . The total purchase price will be paid in cash and approximately $190 million of the purchase consideration was paid to the sellers through December 31, 2018. The remaining amount will be paid in scheduled installments ending in the fourth quarter of 2019 with the final amount based partially on the retention of customer revenue versus a target revenue amount. This contingent consideration arrangement required us to pay a potential amount between $0 to $30 million based on retaining the revenue levels of existing customers at the acquisition date. If there is a shortfall in revenues, a multiple of 2.5 is applied to the revenue shortfall and the contingent consideration to be paid to the former owners is reduced. We used a probability-weighted approach to estimate the fair value of the contingent consideration. The fair value of the contingent consideration reflected in the table below is the present value of the full $15 million which remains potentially payable as of December 31, 2018 as we believe it is unlikely that the contingent consideration payments will be reduced for a revenue shortfall. The Maco Transportadora business is being integrated into our existing Brink’s Argentina operations. Maco Transportadora has approximately 1,450 employees, 4 branches and over 150 armored vehicles across its operations. We have estimated fair values for the assets purchased, liabilities assumed and purchase consideration as of the date of the acquisition in the following table. The determination of estimated fair value required management to make significant estimates and assumptions. There have been no significant changes to our fair value estimates of the net assets acquired for Maco Transportadora.

All of the goodwill has been assigned to the South America reporting unit and is not expected to be deductible for tax purposes. Other acquisitions On March 14, 2017 , we acquired 100% of the capital stock of American Armored Transport, Inc. ("AATI"). AATI provides secured trucking transportation of high-value cargo throughout the continental United States and is expected to complement our existing tractor trailer division in the United States. On April 19, 2017 , we acquired 100% of the capital stock of Muitofacil Holding Ltda., a Brazil-based holding company, and its subsidiary, Muitofacil Arrecadacao e Recebimento Ltda. (together "Pag Facil"). Pag Facil offers bank correspondent services, bill payment processing and mobile phone top-up services in Brazil and is expected to supplement our existing Brazilian payment services businesses. On June 29, 2017 , we acquired 100% of the capital stock of Global Security S.A. (“LGS”). LGS is a Chilean security company specializing in CIT and ATM services and will be integrated into our existing Brink’s Chile operations. On August 14, 2017 , we acquired 100% of the capital stock of Maco Litoral, S.A., (“Maco Litoral”) an Argentina-based company which provides CIT and ATM services. On October 31, 2017 , we acquired 100% of the shares of Temis S.A.S. and its wholly-owned subsidiaries, Les Goelands S.A.S. and Temis Conseil et Formation S.A.R.L (together "Temis"). The Temis business provides CIT and money processing services in France and will be integrated into our existing Brink's France operations. On December 4, 2018 , we acquired 60% of the shares of Worldbridge Secure Logistics Co., Ltd. ("Worldbridge"), a Cambodian company that provides CIT and money processing services. The aggregate purchase price of these six business acquisitions (AATI, Pag Facil, LGS, Maco Litoral, Temis and Worldbridge) was approximately $156 million . These six acquired operations employ approximately 1,800 people in the aggregate. For these six business acquisitions (AATI, Pag Facil, LGS, Maco Litoral, Temis and Worldbridge), we have estimated fair values for the assets purchased and liabilities assumed as of the date of the acquisitions. These estimated amounts are aggregated in the following table. The determination of estimated fair value required management to make significant estimates and assumptions. The amounts included in the table below for the Worldbridge acquisition are considered provisional as we are completing the valuation that is required to allocate the purchase price, as a result, the allocation of the purchase price and the amount of goodwill and intangibles may change in the future. Our fair value estimates of acquisition date goodwill increased approximately $9 million , acquisition date intangible assets decreased approximately $10 million and acquisition date noncurrent liabilities increased approximately $12 million as compared to our initial estimates in the period of acquisition. There have been no other significant changes to our fair value estimates of the net assets acquired for these acquisitions.

(c) Prior to adoption of ASU 2016-01 (see Note 1) in the first quarter of 2018, gains and losses on sales of available-for-sale securities were reclassified from accumulated other comprehensive loss to the consolidated statements of operations when the gains or losses were realized.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	12 Months Ended
Fair Value of Financial Instruments	Dec. 31, 2018
Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Investments in Marketable Securities We have investments in mutual funds that are carried at fair value in the financial statements. For these investments, fair value was based on quoted market prices, which we have categorized as a Level 1 valuation. Fixed-Rate Debt The fair value and carrying value of our fixed-rate debt, excluding any unamortized debt issuance costs, are as follows: December 31, (In millions) 2018 2017 Senior unsecured notes Carrying value $ 600.0 600.0 Fair value 519.9 590.6 The fair value estimate of our senior unsecured notes was based on the present value of future cash flows, discounted at rates for similar instruments at the measurement date, which we have categorized as a Level 3 valuation. Forward and Swap Contracts We have outstanding foreign currency forward and swap contracts to hedge transactional risks associated with foreign currencies. At December 31, 2018 , the notional value of our outstanding foreign currency forward and swap contracts was $168.0 million , with average maturities of approximately two months. These foreign currency forward and swap contracts primarily offset exposures in the euro and the British pound and they are not designated as hedges for accounting purposes. At December 31, 2018 , the fair value of these foreign currency contracts was a net liability of $0.4 million , of which $0.1 million was included in prepaid expenses and other and $0.5 million was included in accrued liabilities on the consolidated balance sheet. In the first quarter of 2016, we entered into two interest rate swaps to hedge cash flow risk associated with changes in variable interest rates and are designated as cash flow hedges for accounting purposes. At December 31, 2018 , the notional value of these contracts was $40 million with a weighted-average maturity of 1.2 years . At December 31, 2018 , the fair value of these interest rate swaps was a net asset of $1.1 million , of which $0.5 million was included in prepaid expenses and other and $0.6 million was included in other assets on the consolidated balance sheet. The fair values of these forward and swap contracts are based on the present value of net future cash payments and receipts, which we have categorized as a Level 2 valuation. Contingent Consideration The estimated fair value of our liability for contingent consideration represents the fair value of the remaining potential amount payable for our acquisition of Maco Transportadora. The remaining contingent amount is expected to be paid in a scheduled second installment in the fourth quarter of 2019, with the final amount paid based partially on the retention of customer revenue versus a target revenue amount. The remaining contingent consideration arrangement requires us to pay potential undiscounted amounts between $0 to $15.1 million based on retaining the revenue levels of existing customers at the acquisition dates. If there is a shortfall in revenues, a multiple of 2.5 is applied to the revenue shortfall and the contingent consideration to be paid to the former owners is reduced. We used a probability-weighted approach to estimate the fair value of this contingent consideration payment. The fair value of the contingent consideration is the full $15.1 million potentially payable as of December 31, 2018 as we believe it is unlikely that the contingent consideration payment will be reduced for a revenue shortfall. At December 31, 2018 , this $15.1 million was included in accrued liabilities on the consolidated balance sheet. The fair value of this liability was estimated using a discounted cash flow technique with significant inputs that are not observable in the market and thus represents a Level 3 valuation. The significant inputs in the Level 3 valuation not supported by market activity included our probability assessments of expected future cash flows related to our acquisition of this entity during the period from acquisition to the estimated settlement date of the remaining payment. The contingent consideration payment may differ from the amount that is ultimately paid, with any changes in the liability recorded in interest and other nonoperating income (expense) in our consolidated statements of operations until the liability is settled. Other Financial Instruments Other financial instruments include cash and cash equivalents, accounts receivable, floating rate debt, accounts payable and accrued liabilities. The financial statement carrying amounts of these items approximate the fair value. There were no transfers in or out of any of the levels of the valuation hierarchy in 2018 .

See Note 20 for more details. Long-Term Debt Senior Secured Credit Facility In October 2017 , we entered into a new senior secured credit facility (the “Senior Secured Credit Facility”) with Wells Fargo Bank, National Association, as administrative agent, consisting of a $1 billion revolving credit facility (the "Revolving Credit Facility") and a $500 million term loan facility (the "Term Loan Facility"). Loans under the Revolving Credit Facility mature five years after the closing date ( October 17, 2022 ) and loans under the Term Loan Facility amortize five percent annually and mature five years after the closing date. Interest rates for the Senior Secured Credit Facility are based on LIBOR plus a margin or an alternate base rate plus a margin. The Revolving Credit Facility allows us to borrow money or issue letters of credit (or otherwise satisfy credit needs) on a revolving basis over the term of the facility. As of December 31, 2018 , $660 million was available under the Revolving Credit Facility. The obligations under the Senior Secured Credit Facility are secured by a first-priority lien on all or substantially all of the assets of the Company and certain of its domestic subsidiaries, including a first-priority lien on equity interests of certain of the Company’s direct and indirect subsidiaries. The Company and certain of its domestic subsidiaries also guarantee the obligations under the Senior Secured Credit Facility. The margin on both LIBOR and alternate base rate borrowings under the Senior Secured Credit Facility is based on the Company’s consolidated net leverage ratio. The margin on LIBOR borrowings, which can range from 1.25% to 2.50% , was 1.75% at December 31, 2018 . The margin on alternate base rate borrowings, which can range from 0.25% to 1.50% , was 0.75% as of December 31, 2018 . We also pay an annual commitment fee on unused portion the Revolving Credit Facility based on the Company’s consolidated net leverage ratio. The commitment fee, which can range from 0.15% to 0.40% , was 0.25% as of December 31, 2018 . Senior Unsecured Notes In October 2017 , we issued at par ten -year senior unsecured notes (the "Senior Notes") in the aggregate principal amount of $600 million . The Senior Notes will mature on October 15, 2027 , bearing an annual interest rate of 4.625% . The Senior Notes are general unsecured obligations guaranteed by certain of the Company’s existing and future U.S. subsidiaries, which are also guarantors under the Senior Secured Credit Facility. The Senior Notes have not been and will not be registered under the Securities Act of 1933 (the “Securities Act”) or the securities laws of any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. The notes were offered in the United States only to persons reasonably believed to be qualified institutional buyers in reliance on the exception from registration set forth in Rule 144A under the Securities Act and outside the United States to non-U.S. persons pursuant to Regulation S under the Securities Act. The aggregate proceeds from the Senior Secured Credit Facility and the Senior Notes were used in part to repay certain prior indebtedness and certain fees and expenses related to the closing of the transactions. Borrowings were used for working capital needs, capital expenditures, acquisitions and other general corporate purposes. Letter of Credit and Bank Guarantee Facilities We have three committed letter of credit facilities totaling $104 million , of which approximately $44 million was available at December 31, 2018 . At December 31, 2018 , we had undrawn letters of credit and guarantees of $60 million issued under these facilities. The $40 million facility expires in January 2019 , the $10 million facility expires in March 2019 and the $54 million facility expires in December 2019 . We have two uncommitted letter of credit facilities totaling $57 million , of which approximately $29 million was available at December 31, 2018 . At December 31, 2018 , we had undrawn letters of credit of $28 million issued under these facilities. The $17 million facility expires in August 2019 and the $40 million facility expires in September 2019 . The Senior Secured Credit Facility is also available for issuance of letters of credit and bank guarantees.

The financial covenants, among other things, limit our ability to provide liens, restrict fundamental changes, limit transactions with affiliates and unrestricted subsidiaries, restrict changes to our fiscal year and to organizational documents, limit asset dispositions, limit the use of proceeds from asset sales, limit sale and leaseback transactions, limit investments, limit the ability to incur debt, restrict certain payments to shareholders, limit negative pledges, limit the ability to change the nature of our business, provide for a maximum consolidated net leverage ratio and provide for minimum coverage of interest costs. If we were not to comply with the terms of our various financing agreements, the repayment terms could be accelerated and the commitments could be withdrawn. An acceleration of the repayment terms under one agreement could trigger the acceleration of the repayment terms under the other financing agreements. We were in compliance with all financial covenants at December 31, 2018 .

Operating Leases	Operating Leases We lease facilities, vehicles, computers and other equipment under long-term operating and capital leases with varying terms. Most of the operating leases contain renewal and/or purchase options. We expect that in the normal course of business, the majority of operating leases will be renewed or replaced by other leases.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation Plans	Share-Based Compensation Plans We have share-based compensation plans to attract and retain employees and nonemployee directors and to more closely align their interests with those of our shareholders. We have outstanding share-based awards granted to employees under the 2013 Equity Incentive Plan (the "2013 Plan") and the 2017 Equity Incentive Plan (the "2017 Plan"). These plans permit grants of restricted stock, restricted stock units, performance stock, performance units, stock appreciation rights, stock options, as well as other share-based awards to eligible employees. The 2013 Plan and the 2017 Plan also permit cash awards to eligible employees. The 2017 Plan became effective May 2017. No further grants of awards will be made under the 2013 Plan, although awards previously granted remain outstanding. We also have outstanding deferred stock units granted to directors under the 2017 Plan. Share-based awards were previously granted to directors and remain outstanding under the Non-Employee Director's Equity Plan and the Directors’ Stock Accumulation Plan, which has expired. There are 5.8 million shares underlying share-based plans that are authorized, but not yet granted. Outstanding awards at December 31, 2018 , include performance share units, restricted stock units, deferred stock units, performance-based stock options, time-based stock options and certain awards that will be settled in cash. Compensation Expense Compensation expense is measured using the fair-value-based method. For awards considered equity grants, compensation expense is recognized from the grant date to the earlier of the retirement-eligible date or the vesting date. For awards considered liability awards, compensation cost is based on the change in the fair value of the instrument for each reporting period and the percentage of the requisite service that has been rendered. Compensation cost associated with liability awards was not significant in the last three years. Compensation expenses are classified as selling, general and administrative expenses in the consolidated statements of operations. Compensation expenses for the last three years and the amount of unrecognized expense for awards outstanding at December 31, 2018 , were as follows: Compensation Expense Unrecognized Expense for Nonvested Awards at Weighted-average No. of Years Unrecognized Expense to be Recognized Years Ended December 31, Dec 31, 2018 (in millions except years) 2018 2017 2016 Performance Share Units $ 15.8 9.5 4.1 $ 16.6 1.7 Market Share Units 0.1 0.3 0.1 — — Restricted Stock Units 6.6 4.7 3.8 3.8 1.3 Deferred Stock Units and fees paid in stock 1.2 1.0 0.9 0.3 0.3 Performance-based Options 4.5 2.2 0.6 6.6 1.8 Time-based Vesting Options — — — — 1.8 Share-based payment expense 28.2 17.7 9.5 Income tax benefit (6.5 ) (3.4 ) (3.0 ) Share-based payment expense, net of tax $ 21.7 14.3 6.5 Fair Value of Distributed or Exercised Awards The fair value of shares distributed or options exercised in the last three years is as follows: Fair Value of Shares Distributed or Exercised (a) Years Ended December 31, (in millions) 2018 2017 2016 Performance Share Units $ 25.3 13.3 8.2 Market Share Units 8.2 4.3 2.7 Restricted Stock Units 8.0 7.3 4.1 Deferred Stock Units and fees paid in stock 0.7 2.7 1.9 Time-based Vesting Options (a) 2.2 2.0 5.3 Total $ 44.4 29.6 22.2 Income tax benefit realized $ 9.9 9.2 7.1 (a) Intrinsic value for options. Restricted Stock Units (“RSUs”) We granted RSUs to select senior executives and employees in the last three years that contain only a service condition. RSUs are paid out in shares of Brink’s stock when the awards vest. For RSUs granted during the last three years, the units generally vest ratably in three equal annual installments. We measure the fair value of RSUs based on the price of Brink’s stock at the grant date, adjusted for a discount for dividends not received or accrued during the vesting period. The weighted-average fair value per share at grant date was $72.31 in 2018 , $55.85 in 2017 and $29.06 in 2016 . The weighted-average discount was approximately 2% in 2018 , 2% in 2017 and 3% in 2016 . The following table summarizes RSU activity during 2018 : Shares (in thousands) Weighted-Average Grant Date Fair Value Per Share Nonvested balance as of December 31, 2017 265.8 $ 39.80 Activity from January 1 to December 31, 2018: Granted 86.3 72.31 Forfeited (7.6 ) 58.27 Vested (108.7 ) 37.64 Nonvested balance as of December 31, 2018 (a) 235.8 $ 52.63 (a) Certain RSUs were modified in the fourth quarter of 2018 and the resulting impact was not material. The weighted-average grant date fair value per share at December 31, 2018 reflects the inclusion of the modified fair value per share for the modified awards. Performance Share Units (“PSUs”) We granted Internal Metric PSUs ("IM PSUs") and Total Shareholder Return PSUs ("TSR PSUs") to select senior executives and employees in the last three years. IM PSUs contain a performance condition as well as a service condition. We measure the fair value of these PSUs based on the price of Brink’s stock at the grant date, adjusted for a discount for dividends not received or accrued during the vesting period. IM PSUs granted in 2018 and 2017 have a three year performance period. For the majority of the IM PSUs granted in 2016, the performance period is two years, with an additional year of service required. Other IM PSUs granted in 2016 have a performance period of one year, with an additional two years of service required. IM PSUs will be paid out in shares of Brink’s stock when the awards vest. For IM PSUs with a performance period greater than one year, the number of shares paid out ranges from 0% to 200% of an employee’s award, depending on the achievement of pre-established financial goals over the performance period, which can be three years or two years depending on the underlying award. Shares are not paid out if the financial results do not meet a pre-established threshold level of performance. For the IM PSUs granted in 2016 that have a one year performance period, the number of shares that will be paid out is either 0% or 100% , depending on the achievement of the specified performance goal. TSR PSUs contain a market condition as well as a service condition. We measure the fair value of TSR PSUs at the grant date using a Monte Carlo simulation model. TSR PSUs granted have a three year performance period and typically vest at the end of three years . TSR PSUs are paid out in shares of Brink’s stock when the awards vest. The number of shares paid out ranges from 0% to 200% of an employee's award for the 2018 TSR PSU grants and from 0% to 150% of an employee’s award for the 2017 and 2016 TSR PSU grants, depending on Brink's relative TSR rank among a selected peer group. The following table summarizes all PSU activity during 2018 : Shares Weighted-Average Grant Date Fair Value Per Share Nonvested balance as of December 31, 2017 671.2 $ 37.26 Activity from January 1 to December 31, 2018: Granted 177.0 73.49 Forfeited (13.2 ) 60.31 Vested (a) (137.7 ) 29.17 Nonvested balance as of December 31, 2018 (b) 697.3 $ 47.74 (a) The vested PSUs presented are based on the target amount of the award. In accordance with the terms of the underlying award agreements, the actual shares earned and distributed for the performance period ended December 31, 2017 were 344.3 . (b) Certain PSUs were modified in the fourth quarter of 2018 and the resulting impact was not material. The weighted-average grant date fair value per share at December 31, 2018 reflects the inclusion of the modified fair value per share for the modified awards. Market Share Units (“MSUs”) Prior to 2016, we granted MSUs, which contained a market condition as well as a service condition. We measured the fair value of MSUs using a Monte Carlo simulation model. MSUs were paid out in shares of Brink’s stock when the award vested. MSUs reward the achievement of the appreciation of Brink’s stock over the performance period (generally three years) at a rate of 0% to 150% of the initial target number of shares awarded. The multiplier to the initial target number of MSUs awarded is calculated as the ratio of the price of Brink’s stock at the end of the performance period divided by the price of Brink’s stock at the beginning of the performance period. If the price of Brink’s stock at the end of the performance period was less than 50% of the initial price, no payout for MSUs would occur. The following table summarizes all MSU activity during 2018 : Shares Weighted-Average Grant Date Fair Value Per Share Nonvested balance as of December 31, 2017 74.2 $ 30.37 Activity from January 1 to December 31, 2018: Vested (a) (74.2 ) 30.37 Nonvested balance as of December 31, 2018 — $ — (a) The vested MSUs presented are based on the target amount of the award. In accordance with the terms of the underlying award agreements, the actual shares earned and distributed for the performance period ended December 31, 2017 were 111.3 . No additional compensation expense was required to be recognized for the additional shares distributed, as the market condition was included in the $30.37 grant date fair value. The following table provides the terms and weighted-average assumptions used in the Monte Carlo simulation model for the TSR PSUs granted in 2018, 2017 and 2016: Terms and Assumptions Used to Estimate Fair Value 2018 TSR PSUs 2017 TSR PSUs 2016 TSR PSUs Terms of awards: Performance period Jan. 1, 2018 to Jan. 1, 2017 to Jan. 1, 2016 to Dec. 31, 2020 Dec. 31, 2019 Dec. 31, 2018 Weighted-average assumptions used to estimate fair value: Expected dividend yield (a) 0.8 % 0.8 % 1.4 % Expected stock price volatility (b) 29.9 % 30.6 % 29.1 % Risk-free interest rate (c) 2.4 % 1.4 % 0.8 % Contractual term in years 2.9 2.9 2.7 Weighted-average fair value estimates at grant date: In millions $ 3.2 $ 2.0 2.3 Fair value per share $ 79.05 $ 67.81 31.64 (a) TSR is determined assuming that dividends are reinvested. The stock price projection in the Monte Carlo simulation model assumed a 0% dividend yield, which is mathematically equivalent to reinvesting dividends over the performance period. For the valuation of the TSR PSU, because the holders of the awards have no rights to any dividend paid during the vesting period, we applied a dividend yield in the Monte Carlo simulation model to reduce the projected stock price as of the grant date. (b) The expected stock price volatility was calculated on the grant date for the most recent term equivalent to the contractual term in years. (c) The risk-free interest rate on each date of grant is the rate for a zero-coupon U.S. Treasury bill that was commensurate with the grant date contractual term. Options In 2018, 2017 and 2016, we granted performance-based stock options to select senior executives. These performance-based awards have a service condition as well as a market condition. In addition, some of the awards granted in 2016 contain a non-financial performance condition. We measure the fair value of these awards at the grant date using a Monte Carlo simulation model. No performance-based options were granted prior to 2016. In 2017 and prior to 2013, we granted time-based vesting stock options to select senior executives and employees and to directors. We measure the fair value of these awards at the grant date using the Black-Scholes-Merton option pricing model. When vested, options entitle the holder to purchase a specified number of shares of Brink’s stock at a price set at the date the options were granted. The option price for Brink’s options was equal to the market price of Brink’s stock on the award date. All options granted to employees have a maximum term of six years . Performance-Based Option Activity The table below summarizes the activity associated with grants of performance-based options: Shares (in thousands) Weighted- Average Exercise Price Per Share Weighted-Average Grant Date Fair Value Per Share Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (a) (in millions) Outstanding at December 31, 2017 879.8 $ 37.95 $ 8.04 Granted 417.6 73.45 16.73 Forfeited or expired (10.4 ) 73.45 17.92 Outstanding at December 31, 2018 (b) 1,287.0 $ 49.18 $ 10.88 4.2 $ 23.5 Of the above, as of December 31, 2018: Exercisable — $ — — $ — Expected to vest in future periods (c) 1,271.2 $ 49.10 4.2 $ 23.3 (a) The intrinsic value of a stock option is the difference between the market price of the shares underlying the option and the exercise price of the option. The market price at December 31, 2018 was $64.65 . (b) Certain performance options were modified in the fourth quarter of 2018 and the resulting impact was not material. The weighted-average grant date fair value per share at December 31, 2018 reflects the inclusion of the modified fair value per share for the modified options. (c) The number of options expected to vest takes into account an estimate of expected forfeitures. We currently have applied a 0% expected forfeiture rate to the majority of the performance-based options. The following table provides the term of the performance period and the weighted-average assumptions used in the Monte Carlo simulation model for the performance-based options: Terms and Assumptions Used to Estimate Fair Value of Performance-Based Options Granted 2018 2017 2016 Terms of awards: Performance period for achieving stock price hurdles Three years from Three years from Three years from grant date grant date grant date Assumptions used to estimate fair value: Expected dividend yield (a) 0.8 % 0.8 % 1.3 % Expected stock price volatility (b) 29.3 % 29.3 % 30.9 % Risk-free interest rate (c) 2.6 % 1.8 % 1.1 % Expected term in years (d) 4.5 4.5 4.5 Weighted-average fair value estimates at grant date: In millions $ 7.0 $ 3.6 $ 3.5 Fair value per share $ 16.73 $ 11.97 $ 6.01 (a) Since the holders of the awards have no rights to any dividend paid during the vesting period, we applied a dividend yield in the Monte Carlo simulation model. At each grant date, the dividend yield was calculated based on the most recent annualized dividend payment and Brink's stock price at the date of grant. (b) The expected stock price volatility was calculated on each grant date for the most recent 4.5 year term. (c) The risk-free interest rate on each grant date is the rate for a zero-coupon U.S. Treasury bill that was commensurate with the expected life of 4.5 years. (d) Because we did not have historical exercise behavior for instruments with premiums, we assumed that the exercise of vested options occurred at the mid-point between the three -year vesting date and the six -year contractual term. In the Monte Carlo simulation, at each iteration of forecasted Brink's stock prices, the option was assumed to be exercised at the mid-point of 4.5 years if the stock price hurdle had been achieved. When the hurdle is achieved, the exercise price was then subtracted from the projected stock price, and discounted back to the grant date. In situations where the projected price had not met the hurdle, no value was attributed. Time-based Vesting Option Activity The table below summarizes the activity associated with grants of time-based vesting options: Shares (in thousands) Weighted- Average Exercise Price Per Share Weighted-Average Grant Date Fair Value Per Share Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (a) (in millions) Outstanding at December 31, 2017 40.6 $ 26.74 $ 8.66 Exercised (37.9 ) 22.57 7.77 Outstanding at December 31, 2018 (b) 2.7 $ 84.65 $ 21.09 4.8 $ — Of the above, as of December 31, 2018: Exercisable — $ — — $ — Expected to vest in future periods (c) 2.4 $ 84.65 4.8 $ — (a) The intrinsic value of a stock option is the difference between the market price of the shares underlying the option and the exercise price of the option. The market price at December 31, 2018 was $64.65 and, as a result, there was no intrinsic value associated with any of the options outstanding at December 31, 2018. (b) There were less than 0.1 million shares of exercisable options with a weighted-average exercise price of $22.57 per share at December 31, 2017 and 0.1 million shares of exercisable options with a weighted-average exercise price of $28.80 per share at December 31, 2016. (c) The number of options expected to vest takes into account an estimate of expected forfeitures. The following table provides the weighted-average assumptions used in the Black-Scholes-Merton option pricing model for the time-based vesting options granted in 2017: Assumptions Used to Estimate Fair Value of Time-Based Options 2017 Assumptions used to estimate fair value: Expected dividend yield (a) 0.7 % Expected stock price volatility (b) 28.9 % Risk-free interest rate (c) 1.7 % Expected term in years (d) 4.5 Weighted-average fair value estimates at grant date: In millions $ 0.1 Fair value per share $ 21.09 (a) The expected dividend yield is the calculated annual yield on Brink's stock at the time of the grant. (b) The expected stock price volatility was calculated at time of the grant after reviewing the historic volatility of our stock using daily close prices. (c) The risk-free interest rate the grant date was the rate for a zero-coupon U.S. Treasury bill that was commensurate with the expected life of 4.5 years. (d) The expected term of the options was based on historical exercise, expiration and post-cancellation behavior. Deferred Stock Units (“DSUs”) We granted DSUs to our nonemployee directors in 2018 and in prior years. We measure the fair value of DSUs at the grant date, based on the price of Brink's stock, and, if applicable, adjusted for a discount for dividends not received or accrued during the vesting period. DSUs granted after 2014 will be paid out in shares of Brink's stock on the first anniversary of the grant date, provided that the director has not elected to defer the distribution of shares until a later date. DSUs granted prior to 2015, in general, will be paid out in shares of stock following separation from service. The following table summarizes all DSU activity during 2018 : Shares (in thousands) Weighted-Average Grant-Date Fair Value Nonvested balance as of December 31, 2017 10.9 $ 60.80 Activity from January 1 to December 31, 2018: Granted 12.5 74.43 Vested (10.9 ) 60.80 Nonvested balance as of December 31, 2018 12.5 $ 74.43 The weighted-average grant-date fair value estimate per share for DSUs granted was $74.43 in 2018 , $60.80 in 2017 and $29.41 in 2016 . Other Share-Based Compensation We have a deferred compensation plan that allows participants to defer a portion of their compensation into stock units. Units will be redeemed by employees for an equal number of shares of Brink’s stock. Employee accounts held 170,672 units at December 31, 2018 , and 145,720 units at December 31, 2017 . We have a stock accumulation plan for our non-employee directors that, prior to 2014, provided for awards of stock units. Additionally, some fees paid to our directors are in the form of stock and may be deferred for distribution to a later date. Directors’ accounts held 18,159 units at December 31, 2018 , and 15,895 units at December 31, 2017 .

Capital Stock	Capital Stock Common Stock At December 31, 2018 , we had 100 million shares of common stock authorized and 49.7 million shares issued and outstanding. Dividends We paid regular quarterly dividends on our common stock during the last three years. On January 17, 2019 , the Board declared a regular quarterly dividend of 15 cents per share payable on March 1, 2019 . The payment of future dividends is at the discretion of the Board of Directors and is dependent on our future earnings, financial condition, shareholder equity levels, cash flow, business requirements and other factors. Preferred Stock At December 31, 2018 , we had the authority to issue up to 2.0 million shares of preferred stock with a par value of $10 per share. Share Repurchase Program In May 2017, our board of directors authorized a $200 million share repurchase program, which will expire on December 31, 2019. We are not obligated to repurchase any specific dollar amount or number of shares, and, at December 31, 2018 , approximately $106 million remains available under this program. The timing and volume of share repurchases may be executed at the discretion of management on an opportunistic basis, or pursuant to trading plans or other arrangements. Share repurchases under this program may be made in the open market, in privately negotiated transactions, or otherwise. In December 2018, we entered into an ASR with a financial institution. In exchange for a $50 million up-front payment at the beginning of the purchase period, the financial institution delivered to us 700,000 shares of our common stock for an average repurchase price of $71.43 per share. The shares received were retired in the period they were delivered to us, and the up-front payment was accounted for as a reduction to shareholders' equity in the consolidated balance sheet. For purposes of calculating earnings per share, we reported the ASR as a repurchase of our common stock in December 2018 and as a forward contract indexed to our common stock. The ASR met all of the applicable criteria for equity classification, and, as a result, was not being accounted for as a derivative instrument. The ASR purchase period subsequently ended in February 2019 and we received and retired an additional 37,387 shares under the ASR, resulting in an overall average repurchase price of $67.81 per share. Additionally, during the year ended December 31, 2018 , we used $43.5 million to repurchase, in the open market, 610,177 shares at an average repurchase price of $71.22 per share. These shares were retired upon repurchase.

Some amounts owed to participants are denominated in common stock units. Each unit represents one share of common stock. The number of shares used to calculate basic earnings per share includes the weighted-average common stock units credited to employees and directors under the deferred compensation plans. Additionally, nonvested units are also included in the computation of basic weighted-average shares when the requisite service period has been completed. Accordingly, basic and diluted shares include weighted-average units of 0.3 million in 2018 , 0.3 million in 2017 and 0.5 million in 2016 .

Through the fourth quarter of 2018, we paid $16.3 million in scheduled installments on the Maco Transportadora acquisition that was completed in the third quarter of 2017. In 2017, we paid $90.9 million in scheduled installments related to the Maco Transportadora acquisition. These payments are reported as cash outflows from financing activities as the payments were made more than three months after the acquisition date. Cash Supply Chain Services In France, we offer services to certain of our customers where we manage some or all of their cash supply chains. Providing this service requires our French subsidiary to take temporary title to the cash received from the management of our customers' cash supply chains until the cash is returned to the customers. As part of this service offering, we have entered into lending arrangements with some of our customers. Cash borrowed under these lending arrangements is used in the process of managing these customers' cash supply chains. The cash for which we have temporary title and the cash borrowed under these customer lending arrangements is restricted and cannot be used for any other purpose other than to service our customers who participate in this service offering. At December 31, 2018 , we held $136.1 million of restricted cash ( $10.5 million represented short-term borrowings, $90.3 million represented restricted cash held for customers and $35.3 million represented accrued liabilities). At December 31, 2017 , we held $112.6 million of restricted cash ( $27.0 million represented short-term borrowings, $74.7 million represented restricted cash held for customers and $ 10.9 million represented accrued liabilities). The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amounts shown in the consolidated statements of cash flows.

Commitments and Contingencies Disclosure [Abstract]
Other Commitments and Contingencies	Other Commitments and Contingencies During the fourth quarter of 2018, we became aware of an investigation initiated by the Chilean Fiscalía Nacional Económica (the Chilean antitrust agency) related to potential anti-competitive practices among competitors in the cash logistics industry in Chile. Because no legal proceedings have been initiated against Brink’s Chile, we cannot estimate the probability of loss or any range of possible loss at this time. It is possible, however, that Brink’s Chile could become the subject of legal or administrative claims or proceedings that could result in a loss in a future period. In addition, we are involved in various other lawsuits and claims in the ordinary course of business. We are not able to estimate the loss or range of losses for some of these matters. We have recorded accruals for losses that are considered probable and reasonably estimable. Except as otherwise noted, we do not believe that it is reasonably possible the ultimate disposition of any of the lawsuits currently pending against the Company could have a material adverse effect on our liquidity, financial position or results of operations. At December 31, 2018 , we had noncancellable commitments for $34.4 million in equipment purchases, and information technology and other services.

Restructuring and Related Activities [Abstract]
Reorganization and Restructuring	Reorganization and Restructuring 2016 Reorganization and Restructuring In the fourth quarter of 2016, management implemented restructuring actions across our global business operations and our corporate functions. As a result of these actions, we recognized $18.1 million in related 2016 costs and an additional $17.3 million in 2017 under this restructuring related to severance, asset-related adjustments, a benefit program termination and lease terminations. We recognized an additional $13.0 million in 2018 under this restructuring for severance costs and asset-related adjustments. The actions under this program were substantially completed in 2018, with cumulative pretax charges of approximately $48 million . Severance actions reduced our global workforce by approximately 800 positions. The following table summarizes the costs incurred, payments and utilization, and foreign currency exchange effects of the 2016 reorganization and restructuring: (In millions) Asset Related Adjustments Severance Costs Lease Terminations Benefit Program Termination Total Balance as of January 1, 2016 $ — — — — — Expense (benefit) 16.3 7.2 0.7 (6.1 ) 18.1 Payments and utilization (16.3 ) (0.2 ) (0.1 ) 6.1 (10.5 ) Balance as of December 31, 2016 $ — 7.0 0.6 — 7.6 Expense (benefit) 4.1 10.4 0.6 2.2 17.3 Payments and utilization (4.1 ) (16.0 ) (0.8 ) (2.2 ) (23.1 ) Foreign currency exchange effects — 0.2 — — 0.2 Balance as of December 31, 2017 $ — 1.6 0.4 — 2.0 Expense (benefit) 1.7 11.3 — — 13.0 Payments and utilization (1.7 ) (12.4 ) (0.2 ) — (14.3 ) Foreign currency exchange effects — — — — — Balance as of December 31, 2018 $ — 0.5 0.2 — 0.7 Executive Leadership and Board of Directors Restructuring In January 2016, we announced Executive Leadership and Board of Directors restructuring actions and we recognized $4.3 million in charges in 2016 related to these actions. 2015 Reorganization and Restructuring Brink's initiated a global restructuring of its business in the third quarter of 2015. We recognized $6.5 million in 2016 related to this restructuring for severance costs, contract terminations and lease terminations. The 2015 reorganization and restructuring reduced the global workforce by approximately 1,100 positions and resulted in approximately $20 million in 2016 savings. The actions under this program were substantially completed by the end of 2016, with cumulative pretax charges of approximately $18 million . Other Restructurings Management periodically implements restructuring actions in targeted sections of our business. As a result of these actions, we recognized costs of $4.6 million in 2017 and $7.6 million in 2018, primarily severance costs. For the current restructuring actions, we expect to incur additional costs between $5 million and $7 million in future periods.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Business Acquisition In January 2019 , we acquired 100% of the capital stock of Rodoban Transportes Aereos e Terrestres Ltda., Rodoban Servicos e Sistemas de Seguranca Ltda., and Rodoban Seguranca e Transporte de Valores Ltda. (together "Rodoban") in Brazil for approximately $130 million . Rodoban provides cash-in-transit, money processing and ATM services and generates annual revenues of approximately $80 million . We are in the process of completing our initial accounting for this business combination. Senior Secured Credit Facility Amendment In February 2019 , we amended our Senior Secured Credit Facility, which includes a $1 billion Revolving Credit Facility and a Term Loan Facility. Under the amendment, we increased our Term Loan Facility principal outstanding from approximately $469 million to $800 million . The proceeds from the amendment were used to repay outstanding principal under the Revolving Credit Facility as well as certain fees related to the closing of the transaction. Principal payments are due quarterly for the amended Term Loan Facility equal to 1.25% of the initial loan amount with a final payment due in February 2024 . The maturity date for the Revolving Credit Facility was also extended from October 2022 to February 2024 . Interest Rate Swaps In February 2019 , we entered into a series of interest rate swaps with a total notional value of $400 million . These interest rate swaps are intended to hedge cash flow risk associated with our variable interest rate debt as we have locked into a fixed interest rate over the term of these contracts. We have designated these interest rate swaps as cash flow hedges for accounting purposes.

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Brink’s Company (along with its subsidiaries, “we,” “our,” “Brink’s” or the “Company”), based in Richmond, Virginia, is a leading provider of secure transportation, cash management services and other security-related services to banks and financial institutions, retailers, government agencies, mints, jewelers and other commercial operations around the world. Brink’s is the oldest and largest secure transportation and cash management services company in the U.S., and a market leader in many other countries.
Principles of Consolidation	Consolidation The consolidated financial statements include our controlled subsidiaries. Control is determined based on ownership rights or, when applicable, based on whether we are considered to be the primary beneficiary of a variable interest entity. See "Venezuela" section below for further information. For controlled subsidiaries that are not wholly-owned, the noncontrolling interests are included in net income and in total equity. Investments in businesses that we do not control, but for which we have the ability to exercise significant influence over operating and financial policies, are accounted for under the equity method and our proportionate share of income or loss is recorded in other operating income (expense). Investments in businesses for which we do not have the ability to exercise significant influence over operating and financial policies are accounted for at fair value, if readily determinable, with changes in fair value recognized in net income. For equity investments that do not have a readily determinable fair value, we measure these investments at cost minus impairment, if any, plus or minus changes from observable price changes. See "New Accounting Standards" section below for further information. All intercompany accounts and transactions have been eliminated in consolidation.
Revenue Recognition	Revenue Recognition Revenue is recognized when services related to armored vehicle transportation, ATM services, cash management services, payment services, guarding and the secure international transportation of valuables are performed. We assess our customers' ability to meet contractual terms, including payment terms, before entering into contracts. Taxes collected from customers and remitted to governmental authorities are not included in revenues in the consolidated statements of operations. The amount of revenue recognized in 2018 that was included in the January 1, 2018 contract liability balance was $5.6 million . This revenue consists of services provided to customers who had prepaid for those services prior to the current year. We also recognized revenue of $0.6 million in 2018 from performance obligations satisfied in the prior year. This amount is a result of changes in the transaction price of our contracts with customers. Contract Costs Sales commissions directly related to obtaining new contracts with customers qualify for capitalization. These capitalized costs are amortized to expense ratably over the term of the contracts. At December 31, 2018 , the net capitalized costs to obtain contracts was $1.8 million , which is included in other assets on the consolidated balance sheet. Amortization expense in 2018 was not significant and there were no impairment losses recognized related to these contract costs in 2018. Practical Expedients For the majority of our contracts with customers, we invoice a fixed amount for each unit of service we have provided. These contracts provide us with the right to invoice for an amount or rate that corresponds to the value we have delivered to our customers. The volume of services that will be provided to customers over the term is not known at inception of these contracts. Therefore, while the rate per unit of service is known, the transaction price itself is variable. For this reason, we recognize revenue from these contracts equal to the amount for which we have the contractual right to invoice the customers. Because we are not required to estimate variable consideration related to the transaction price in order to recognize revenue, we are also not required to estimate the variable consideration to provide certain disclosures. As a result, we have elected to use the optional exemption related to the disclosure of transaction prices, amounts allocated to remaining performance obligations and the future periods in which revenue will be recognized, sometimes referred to as backlog. We have also elected to use the practical expedient for financing components related to our contract liabilities. We do not recognize interest expense on contracts for which the period between our receipt of customer payments and our service to the customer is one year or less. For performance obligations related to the services described above, we generally satisfy our obligations as each action to provide the service to the customer occurs. Because the customers simultaneously receive and consume the benefits from our services, these performance obligations are deemed to be satisfied over time. We use an output method, units of service provided, to recognize revenue because that is the best method to represent the transfer of our services to the customer at the agreed upon rate for each action. Although not as significant as our service offerings, we also sell goods to customers from time to time, such as safe devices. In those transactions, we satisfy our performance obligation at a point in time. We recognize revenue when the goods are delivered to the customer as that is the point in time that best represents when control has transferred to the customer. Our contracts with customers describe the services we can provide along with the fees for each action to provide the service. We typically send invoices to customers for all of the services we have provided within a monthly period and payments are generally due within 30 to 60 days of the invoice date. Although our customer contracts specify the fees for each action to provide service, the majority of the services stated in our contracts do not have a defined quantity over the contract term. Accordingly, the transaction price is considered variable as there is an unknown volume of services that will be rendered over the course of the contract. We recognize revenue for these services in the period in which they are provided to the customer based on the contractual rate at which we have the right to invoice the customer for each action. Some of our contracts with customers contain clauses that define the level of service that the customer will receive. The service level agreements (“SLA”) within those contracts contain specific calculations to determine whether the appropriate level of service has been met within a specific period, which is typically a month. We estimate SLA penalties and recognize the amounts as a reduction to revenue. Taxes collected from customers and remitted to governmental authorities are not included in revenues in the consolidated statements of operations. The majority of our revenues from contracts with customers are earned by providing services and these performance obligations are satisfied over time. Smaller amounts of revenues are earned from selling goods, such as safes, to customers where the performance obligations are satisfied at a point in time. Certain of our high-value services involve the leasing of assets, such as safes, to our customers along with the regular servicing of those safe devices. Revenues related to the leasing of these assets are recognized in accordance with ASC 840, Leases , but are included in the above table as the amounts are a small percentage of overall revenues. Contract Balances Contract Asset Although payment terms and conditions can vary, for the majority of our customer contracts, we invoice for all of the services provided to the customer within a monthly period. For certain customer contracts, the timing of our performance may precede our right to invoice the customer for the total transaction price. For example, Brink's affiliates in certain countries, primarily in South America, negotiate annual price adjustments with certain customers and, once the price increases are finalized, the pricing changes are made retroactive to services provided in earlier periods. These retroactive pricing adjustments are estimated and recognized as revenue with a corresponding contract asset in the same period in which the related services are performed. As the estimate of the ultimate transaction price changes, we recognize a cumulative catch-up adjustment for the change in estimate. Contract Liability For other customer contracts, we may obtain the right to payment or receive customer payments prior to performing the related services under the contract. When the right to customer payments or receipt of payments precedes our performance, we recognize a contract liability.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits and investments with original maturities of three months or less. Cash and cash equivalents include amounts held by certain of our secure cash management services operations for customers for which, under local regulations, the title transfers to us for a short period of time. The cash is generally credited to customers’ accounts the following day and we do not consider it as available for general corporate purposes in the management of our liquidity and capital resources. We record a liability for the amounts owed to customers (see Note 13).
Trade Accounts Receivable	Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses on our existing accounts receivable. We determine the allowance based on historical write-off experience. We review our allowance for doubtful accounts quarterly. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost. Depreciation is calculated principally on the straight-line method based on the estimated useful lives of individual assets or classes of assets. Leased property and equipment meeting capital lease criteria are capitalized at the lower of the present value of the related lease payments or the fair value of the leased asset at the inception of the lease. Amortization is calculated on the straight-line method based on the lease term. See "New Accounting Standards" section below for further information. Leasehold improvements are recorded at cost. Amortization is calculated principally on the straight-line method over the lesser of the estimated useful life of the leasehold improvement or the lease term. Renewal periods are included in the lease term when the renewal is determined to be reasonably assured. Part of the costs related to the development or purchase of internal-use software is capitalized and amortized over the estimated useful life of the software. Costs that are capitalized include external direct costs of materials and services to develop or obtain the software, and internal costs, including compensation and employee benefits for employees directly associated with a software development project. Estimated Useful Lives Years Buildings 16 to 25 Building leasehold improvements 3 to 10 Vehicles 3 to 10 Capitalized software 3 to 5 Other machinery and equipment 3 to 10 Expenditures for routine maintenance and repairs on property and equipment are charged to expense. Major renewals, betterments and modifications are capitalized and depreciated over the lesser of the remaining life of the asset or, if applicable, the lease term.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill is recognized for the excess of the purchase price over the fair value of tangible and identifiable intangible net assets of businesses acquired. Intangible assets arising from business acquisitions include customer lists, customer relationships, covenants not to compete, trademarks and other identifiable intangibles. At December 31, 2018 , finite-lived intangible assets have remaining useful lives ranging from 1 to 15 years and are amortized based on the pattern in which the economic benefits are used or on a straight-line basis.
Impairment of Goodwill and Long-Lived Assets	Impairment of Goodwill and Long-Lived Assets Goodwill is not amortized but is tested at least annually for impairment at the reporting unit level, which is one level below an operating segment. Goodwill is assigned to one or more reporting units at the date of acquisition. Effective February 2017, we implemented changes to our organization and management structure. After the February 2017 reorganization, we have eight reporting units: • U.S. • Mexico • Canada • France • Brazil • Global Markets - South America • Global Markets - EMEA • Global Markets - Asia We performed goodwill impairment tests on the reporting units that had goodwill as of October 1, 2018. We performed a quantitative analysis to determine whether reporting unit fair values exceeded their carrying amounts. We based our estimates of fair value on projected future cash flows. With one exception, we concluded that the fair value of each reporting unit substantially exceeded its carrying value by a range of 57% to 236% . For the France reporting unit, which has $91.2 million of goodwill at December 31, 2018, fair value exceeded carrying value by approximately 9% . We completed these impairment tests, as well as the tests in the previous two years, with no impairment charges required. Indefinite-lived intangibles are also tested for impairment at least annually by comparing their carrying values to their estimated fair values. We have had no significant impairments of indefinite-lived intangibles in the last three years. Long-lived assets other than goodwill and other indefinite-lived intangibles are reviewed for impairment when events or changes in circumstances indicate the carrying value of an asset may not be recoverable. For long-lived assets other than goodwill that are to be held and used in operations, an impairment is indicated when the estimated total undiscounted cash flow associated with the asset or group of assets is less than carrying value. If impairment exists, an adjustment is made to write the asset down to its fair value, and a loss is recorded as the difference between the carrying value and fair value.
Retirement Benefit Plans	Retirement Benefit Plans We account for retirement benefit obligations under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 715, Compensation – Retirement Benefits . For U.S. and certain non-U.S. retirement plans, we derive the discount rates used to measure the present value of benefit obligations using the cash flow matching method. Under this method, we compare the plan’s projected payment obligations by year with the corresponding yields on a Mercer yield curve. Each year’s projected cash flows are then discounted back to their present value at the measurement date and an overall discount rate is determined. The overall discount rate is then rounded to the nearest tenth of a percentage point. We used Mercer’s Above-Mean Curve to determine the discount rates for the year-end benefit obligations and retirement cost of our U.S. retirement plans. We use a local or regional version of the Mercer yield curve in the majority of our non-U.S. locations. In non-U.S. locations where the cash flow matching method is not possible, rates of local high-quality long-term government bonds are used to select the discount rate. We select the expected long-term rate of return assumption for our U.S. pension plan and retiree medical plans using advice from our investment advisor. The selected rate considers plan asset allocation targets, expected overall investment manager performance and long-term historical average compounded rates of return. Benefit plan actuarial gains and losses are recognized in other comprehensive income (loss). Accumulated net benefit plan actuarial gains and losses that exceed 10% of the greater of a plan’s benefit obligation or plan assets at the beginning of the year are amortized into earnings from other comprehensive income (loss) on a straight-line basis. The amortization period for pension plans is the average remaining service period of employees expected to receive benefits under the plans. The amortization period for other retirement plans is primarily the average remaining life expectancy of inactive participants.
Income Taxes	Income Taxes Deferred tax assets and liabilities are recorded to recognize the expected future tax benefits or costs of events that have been, or will be, reported in different years for financial statement purposes than tax purposes. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which these items are expected to reverse. We recognize tax benefits related to uncertain tax positions if we believe it is more likely than not the benefit will be realized. We review our deferred tax assets to determine if it is more-likely-than-not that they will be realized. If we determine it is not more-likely-than-not that a deferred tax asset will be realized, we record a valuation allowance to reverse the previously recognized tax benefit.
Foreign Currency Translation	Foreign Currency Translation Our consolidated financial statements are reported in U.S. dollars. Our foreign subsidiaries maintain their records primarily in the currency of the country in which they operate. The method of translating local currency financial information into U.S. dollars depends on whether the economy in which our foreign subsidiary operates has been designated as highly inflationary or not. Economies with a three-year cumulative inflation rate of more than 100% are considered highly inflationary. Assets and liabilities of foreign subsidiaries in non-highly inflationary economies are translated into U.S. dollars using rates of exchange at the balance sheet date. Translation adjustments are recorded in other comprehensive income (loss). Revenues and expenses are translated at rates of exchange in effect during the year. Transaction gains and losses are recorded in net income. Foreign subsidiaries that operate in highly inflationary countries use the U.S. dollar as their functional currency. Local currency monetary assets and liabilities are remeasured into U.S. dollars using rates of exchange as of each balance sheet date, with remeasurement adjustments and other transaction gains and losses recognized in earnings. Other than nonmonetary equity securities, nonmonetary assets and liabilities do not fluctuate with changes in local currency exchange rates to the dollar. For nonmonetary equity securities traded in highly inflationary economies, the fair market value of the equity securities are remeasured at the current exchange rates to determine gain or loss to be recorded in net income. Revenues and expenses are translated at rates of exchange in effect during the year. See "Venezuela" and "Argentina" sections below for further information. Venezuela Deconsolidation . Our Venezuelan operations offer transportation and route-based logistics management services for cash and valuables throughout Venezuela. Political and economic conditions in Venezuela, the impact of local laws on our business as well as the currency exchange control regulations and continued reductions in access to U.S. dollars through official currency exchange mechanisms, resulted in an other-than-temporary lack of exchangeability between the Venezuelan bolivar and the U.S. dollar. These conditions restricted the ability of our Venezuelan operations to pay dividends and royalties. It also restricted the ability for our Venezuela business to settle other operating liabilities which significantly increased the risk that this business will no longer be self-sustaining. Our Venezuela operations experienced negative operating cash flows in the first quarter of 2018. As a result, our Venezuela business obtained local currency borrowings in the first and second quarters of 2018 for the first time since the second quarter of 2016. Our Venezuela business will seek additional local financing to support ongoing needs for more bolivars in an environment with significant inflation. It is uncertain as to whether our Venezuela business will be able to obtain the incremental financing in order to operate the business. Banks provide a majority of the business for our Venezuela operations and these banks are limited by law as to how much they can charge their customers in interest. The maximum increase to interest allowable under the law is significantly lower than current and projected inflation rates. Therefore, we do not believe that bank customers will accept increases in our prices that will cover our increase in vendor and labor costs resulting from inflation. Through its restriction by law of interest increases for banks, the Venezuelan government has implemented a defacto price control that affected our business. The currency exchange regulations, combined with other government regulations, such as price controls and strict labor laws, significantly limited our ability to make and execute operational decisions at our Venezuelan subsidiaries. With the May 2018 re-election of the President in Venezuela for an additional six-year term, we expect these conditions to continue for the foreseeable future. As a result of the conditions described above, we concluded that, effective June 30, 2018, we did not meet the accounting criteria for control over our Venezuelan operations and, as a result, we began reporting the results of our investment in our Venezuelan subsidiaries using the cost method of accounting. This change resulted in a pretax charge of $127 million in the second quarter of 2018. The pretax charge included $106 million of foreign currency translation losses and benefit plan adjustments previously included in accumulated other comprehensive loss. It also included the derecognition of the carrying amounts of our Venezuelan operations’ assets and liabilities, including $32 million of assets and $11 million of liabilities, that were no longer reported in our consolidated balance sheet as of June 30, 2018. We determined the fair value of our investment in, and receivables from, our Venezuelan subsidiaries to be insignificant based on our expectations of dividend payments and settlements of such receivables in future periods. For reporting periods beginning after June 30, 2018, we have not included the operating results of our Venezuela operations. In 2018 and 2017, we provided immaterial amounts of financial support to our Venezuela operations. Our exposure to future losses resulting from our Venezuelan business is limited to the extent to which we decide to provide U.S. dollars or make future investments in our Venezuelan subsidiaries. We continue to monitor the situation in Venezuela. Highly Inflationary Accounting . The economy in Venezuela has had significant inflation in the last several years. Prior to deconsolidation as of June 30, 2018, we reported our Venezuelan results using our accounting policy for subsidiaries operating in highly inflationary economies. Results from our Venezuelan operations prior to the June 30, 2018 deconsolidation are included in items not allocated to segments and are excluded from the operating segments.
Restricted Cash	Restricted Cash In France, we offer services to certain of our customers where we manage some or all of their cash supply chains. In connection with this offering, we take temporary title to certain customers' cash, which is included as restricted cash in our financial statements due to customer agreement or regulation (see Note 20).
Concentration of Credit Risks	Concentration of Credit Risks We routinely assess the financial strength of significant customers and this assessment, combined with the large number and geographic diversity of our customers, limits our concentration of risk with respect to accounts receivable. Financial instruments which potentially subject us to concentrations of credit risks are principally cash and cash equivalents and accounts receivables. Cash and cash equivalents are held by major financial institutions.
Use of Estimates	Use of Estimates In accordance with U.S. generally accepted accounting principles (“GAAP”), we have made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these consolidated financial statements. Actual results could differ materially from those estimates. The most significant estimates are related to goodwill, intangibles and other long-lived assets, pension and other retirement benefit assets and obligations, legal contingencies, deferred tax assets, purchase price allocations and foreign currency translation.
Fair-value estimates	Fair-value estimates. We have various financial instruments included in our financial statements. Financial instruments are carried in our financial statements at either cost or fair value. We estimate fair value of assets using the following hierarchy using the highest level possible: Level 1: Quoted prices for identical assets or liabilities in active markets. Level 2: Quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are directly or indirectly observable, or inputs that are derived principally from, or corroborated by, observable market data by correlation or other means. Level 3: Unobservable inputs that reflect estimates and assumptions.
New Accounting Standards	New Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue From Contracts with Customers. Under this standard, an entity recognizes an amount of revenue to which it expects to be entitled when the transfer of goods or services to customers occurs. The standard requires expanded disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. We adopted this standard effective January 1, 2018 using the modified retrospective method and recognized a cumulative-effect adjustment increasing retained earnings by $1.5 million . The most significant effects of the standard for us are associated with variable consideration and capitalization of costs to obtain contracts, such as sales commissions. Previously, we recognized the impact of pricing changes in the period they became fixed and determinable, and we expensed sales commissions and other costs to obtain contracts as they were incurred. We do not expect a material impact on our future consolidated statements of operations or consolidated balance sheets as a result of implementing this standard. However, adoption of the standard resulted in expanded disclosures related to revenue (see Note 2). The FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, in January 2016. This standard changes the accounting related to the classification and measurement of certain equity investments. Equity investments with readily determinable fair values must be measured at fair value. All changes in fair value will be recognized in net income as opposed to other comprehensive income. We adopted ASU 2016-01 effective January 1, 2018 and recognized a cumulative-effect adjustment increasing retained earnings by $1.1 million . In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting , which simplifies how certain features related to share-based payments are accounted for and presented in the financial statements. We elected to early adopt this ASU in the fourth quarter of 2016 and, per the requirements of the pronouncement, we applied the amendments to the beginning of 2016. Under ASU 2016-09, accounting changes adopted using the modified retrospective method were calculated as of the beginning of 2016 and reported as a cumulative-effect adjustment. As a result, we recognized a $0.2 million cumulative-effect adjustment to January 1, 2016 retained earnings for previously unrecognized excess tax benefits. We elected to continue our previous accounting policy of estimating forfeitures and, therefore, we did not recognize any cumulative-effect adjustment related to forfeitures. ASU 2016-09 requires that accounting changes adopted using the prospective method should be reported in the applicable interim periods of 2016. We did not have any material changes to previously reported interim financial information in 2016 as it relates to the recognition of excess tax benefits in the statements of operations or the classification of excess tax benefits in the statements of cash flows. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory , which changes the timing of when certain intercompany transactions are recognized within the provision for income taxes. We adopted ASU 2016-16 effective January 1, 2018 using the modified retrospective method and we recognized a cumulative-effect adjustment increasing retained earnings by $0.7 million . The FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash , in November 2016. This standard requires entities to include restricted cash and restricted cash equivalent balances with cash and cash equivalent balances in the statements of cash flows. Inclusion of restricted cash impacts our operating activities, financing activities and the effect of exchange rate changes on cash. We adopted ASU 2016-18 effective January 1, 2018 using the retrospective transition method. The adoption of this ASU changed previously reported amounts in the consolidated statements of cash flows. Net cash provided by operating activities increased $44.3 million , net cash provided by financing activities increased $1.5 million and the effect of exchange rate changes on cash decreased favorably by $11.3 million as compared to previously reported amounts for the year ended December 31, 2017. Net cash provided by operating activities increased $22.8 million , net cash used by financing activities decreased $19.9 million and the effect of exchange rate changes on cash increased unfavorably by $3.6 million as compared to previously reported amounts for the year ended December 31, 2016. In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , which requires an entity to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. We elected to early adopt this ASU in the first quarter of 2017 using the retrospective transition method for the periods presented. As a result, the consolidated statements of operations were updated to reflect this guidance. The early adoption of this ASU had no impact on the previously reported income from continuing operations or net income for the prior year periods. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which will require the recognition of right-of-use assets and lease liabilities by lessees for certain leases classified as operating leases under current accounting guidance and will also require expanded disclosures regarding leasing activities. The accounting for capital leases remains substantially unchanged. ASU 2016-02 will be effective January 1, 2019 and we have elected to adopt the new standard at the adoption date through a cumulative-effect adjustment to the opening balance of retained earnings. Under this approach, we will continue to report comparative periods presented in the period of adoption under ASC 840. We have elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allows us to carry forward the historical lease classification. We also made an accounting policy election to keep leases with an initial term of 12 months or less off of the balance sheet. We will recognize those lease payments in the consolidated statements of operations on a straight-line basis over the lease term. In preparation for adoption of the standard, we are implementing internal controls and key system functionality to enable the preparation of financial information. We are still in the process of finalizing our opening balance sheet adjustment, but we estimate adoption of the standard will result in recognition of additional lease assets and lease liabilities in the range of $260 million and $360 million as of January 1, 2019. We do not believe the standard will materially affect our consolidated statements of operations or our consolidated statements of cash flows. The standard will have no impact on our debt-covenant compliance under our current agreements. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments , which significantly changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life. ASU 2016-13 is effective January 1, 2020, with early adoption permitted January 1, 2019. We are assessing the potential impact of this new standard on financial reporting. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other: Simplifying the Test for Goodwill Impairment , which requires an entity to no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. The guidance is effective January 1, 2020 with early adoption permitted. We are currently evaluating the impact of this guidance, including transition elections and required disclosures, on our financial statements and the timing of adoption. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities , which amends and simplifies the application of hedge accounting guidance to better portray the economic results of risk management activities in the financial statements. The guidance expands the ability to hedge nonfinancial and financial risk components, reduces complexity in fair value hedges of interest rate risk, eliminates the requirement to separately measure and report hedge ineffectiveness, and eases certain hedge effectiveness assessment requirements. The guidance is effective January 1, 2019 and we do not expect any significant impact on our consolidated financial statements upon adoption. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (“Tax Reform Act”). The guidance is effective January 1, 2019. We are evaluating the potential impact of the standard on financial reporting and we will determine whether we will reclassify amounts before the end of the first quarter of 2019. In August 2018, the FASB issued ASU 2018-13, Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement , which changes the fair value measurement disclosure requirements. The guidance is effective January 1, 2020 with early adoption permitted. We are currently evaluating the potential impact of the standard on financial reporting and the timing of adoption. In August 2018, the FASB issued ASU 2018-14, Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans , to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The guidance is effective January 1, 2021 with early adoption permitted. We adopted this guidance in the fourth quarter of 2018 and, as a result, our retirement benefits note no longer includes disclosures related to amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost in the next fiscal year. Our retirement benefits note also no longer includes disclosures regarding the effects of a one-percentage-point change in assumed health care cost trend rates on the aggregate of the service and interest cost components of net periodic benefit costs and the benefit obligation for retirement benefits other than pensions. All other provisions of this ASU were either not applicable to us or we were already disclosing the information required.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Revenue is recognized when services related to armored vehicle transportation, ATM services, cash management services, payment services, guarding and the secure international transportation of valuables are performed. We assess our customers' ability to meet contractual terms, including payment terms, before entering into contracts. Taxes collected from customers and remitted to governmental authorities are not included in revenues in the consolidated statements of operations. The amount of revenue recognized in 2018 that was included in the January 1, 2018 contract liability balance was $5.6 million . This revenue consists of services provided to customers who had prepaid for those services prior to the current year. We also recognized revenue of $0.6 million in 2018 from performance obligations satisfied in the prior year. This amount is a result of changes in the transaction price of our contracts with customers. Contract Costs Sales commissions directly related to obtaining new contracts with customers qualify for capitalization. These capitalized costs are amortized to expense ratably over the term of the contracts. At December 31, 2018 , the net capitalized costs to obtain contracts was $1.8 million , which is included in other assets on the consolidated balance sheet. Amortization expense in 2018 was not significant and there were no impairment losses recognized related to these contract costs in 2018. Practical Expedients For the majority of our contracts with customers, we invoice a fixed amount for each unit of service we have provided. These contracts provide us with the right to invoice for an amount or rate that corresponds to the value we have delivered to our customers. The volume of services that will be provided to customers over the term is not known at inception of these contracts. Therefore, while the rate per unit of service is known, the transaction price itself is variable. For this reason, we recognize revenue from these contracts equal to the amount for which we have the contractual right to invoice the customers. Because we are not required to estimate variable consideration related to the transaction price in order to recognize revenue, we are also not required to estimate the variable consideration to provide certain disclosures. As a result, we have elected to use the optional exemption related to the disclosure of transaction prices, amounts allocated to remaining performance obligations and the future periods in which revenue will be recognized, sometimes referred to as backlog. We have also elected to use the practical expedient for financing components related to our contract liabilities. We do not recognize interest expense on contracts for which the period between our receipt of customer payments and our service to the customer is one year or less. For performance obligations related to the services described above, we generally satisfy our obligations as each action to provide the service to the customer occurs. Because the customers simultaneously receive and consume the benefits from our services, these performance obligations are deemed to be satisfied over time. We use an output method, units of service provided, to recognize revenue because that is the best method to represent the transfer of our services to the customer at the agreed upon rate for each action. Although not as significant as our service offerings, we also sell goods to customers from time to time, such as safe devices. In those transactions, we satisfy our performance obligation at a point in time. We recognize revenue when the goods are delivered to the customer as that is the point in time that best represents when control has transferred to the customer. Our contracts with customers describe the services we can provide along with the fees for each action to provide the service. We typically send invoices to customers for all of the services we have provided within a monthly period and payments are generally due within 30 to 60 days of the invoice date. Although our customer contracts specify the fees for each action to provide service, the majority of the services stated in our contracts do not have a defined quantity over the contract term. Accordingly, the transaction price is considered variable as there is an unknown volume of services that will be rendered over the course of the contract. We recognize revenue for these services in the period in which they are provided to the customer based on the contractual rate at which we have the right to invoice the customer for each action. Some of our contracts with customers contain clauses that define the level of service that the customer will receive. The service level agreements (“SLA”) within those contracts contain specific calculations to determine whether the appropriate level of service has been met within a specific period, which is typically a month. We estimate SLA penalties and recognize the amounts as a reduction to revenue. Taxes collected from customers and remitted to governmental authorities are not included in revenues in the consolidated statements of operations. The majority of our revenues from contracts with customers are earned by providing services and these performance obligations are satisfied over time. Smaller amounts of revenues are earned from selling goods, such as safes, to customers where the performance obligations are satisfied at a point in time. Certain of our high-value services involve the leasing of assets, such as safes, to our customers along with the regular servicing of those safe devices. Revenues related to the leasing of these assets are recognized in accordance with ASC 840, Leases , but are included in the above table as the amounts are a small percentage of overall revenues. Contract Balances Contract Asset Although payment terms and conditions can vary, for the majority of our customer contracts, we invoice for all of the services provided to the customer within a monthly period. For certain customer contracts, the timing of our performance may precede our right to invoice the customer for the total transaction price. For example, Brink's affiliates in certain countries, primarily in South America, negotiate annual price adjustments with certain customers and, once the price increases are finalized, the pricing changes are made retroactive to services provided in earlier periods. These retroactive pricing adjustments are estimated and recognized as revenue with a corresponding contract asset in the same period in which the related services are performed. As the estimate of the ultimate transaction price changes, we recognize a cumulative catch-up adjustment for the change in estimate. Contract Liability For other customer contracts, we may obtain the right to payment or receive customer payments prior to performing the related services under the contract. When the right to customer payments or receipt of payments precedes our performance, we recognize a contract liability.

(d) This category consists of a diversified portfolio of debt securities issued by governments, financial institutions, companies or other entities domiciled in emerging market countries. (e) This category is designed to achieve a return consistent with holding longer term debt instruments. This category invests in interest rate and inflation derivatives, government-issued bonds, real-return bonds, and futures contracts.

(b) This category represents an actively managed mutual fund that invests primarily in equity securities of emerging market issuers. Emerging market countries are those countries that are characterized as developing or emerging by any of the World Bank, the United Nations, the International Finance Corporation, or the European Bank for Reconstruction and Development or included in an emerging markets index by a recognized index provider. (c) This category represents an actively managed mutual fund that seeks to generate total return over time by selecting investments from among a broad range of asset classes. The fund’s allocations among asset classes may be adjusted over short periods and can vary from multiple to a single asset class. (d) This category represents actively managed mutual funds that seek to duplicate the risk and return characteristics of a long-term fixed-income security portfolio with approximate duration of 10 to 15 years and longer by using a long duration bond portfolio. This category also includes Treasury future contracts and zero -coupon securities created by the U.S. Treasury. (e) This category represents an actively managed mutual fund that invests primarily in fixed-income securities rated below investment grade, including corporate bonds and debentures, convertible and preferred securities and zero-coupon obligations. The fund’s average weighted maturity may vary and will generally not exceed ten years. (f) This category represents an actively managed mutual fund that invests primarily in U.S. dollar-denominated debt securities of government, government-related and corporate issuers in emerging market countries, as well as entities organized to restructure the outstanding debt of such issuers. (g) This category represents an actively managed real estate fund of funds that seeks both current income and long-term capital appreciation through investing in underlying funds that acquire, manage, and dispose of commercial real estate properties. These properties are high-quality, low-leveraged, income-generating office, industrial, retail, and multi-family properties, generally fully-leased to creditworthy companies and governmental entities. (h) This category invests primarily in a diversified portfolio comprised primarily of collateralized loan obligations and other structured credit investments backed primarily by bank loans. (i) This category represents an actively managed mutual fund that invests primarily in fixed income and equity securities and commodity linked instruments. The category seeks total returns that exceed the rate of inflation over a full market cycle regardless of market conditions. (j) This category will offer exposure to a diversified pool of global private assets fund investments. Further, the category will seek to shorten the duration of the typical private assets fund of funds through a dedicated focus on secondary strategies (i.e. funds whose investment strategy is to purchase interests in other private market investments/funds as a way to provide the original investors liquidity prior to the end of those investments’/funds’ contracted end date), income-producing investment strategies (e.g. debt, real estate, and to a lesser extent, real assets), and underlying funds whose stated life is five to seven years, as opposed to the more typical 10 -year life of private assets funds. (k) This category invests in credit securities of commodity oriented companies affected by the dislocation in the commodity markets with the investment objective of producing an equity like return with less downside risk than equity or commodity investments. (l) In accordance with Subtopic 820-10, certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the consolidated balance sheets.

The U.S. foreign tax credits and other U.S. tax credits have a valuation allowance.
Summary of Valuation Allowance	Based on our analysis of positive and negative evidence including historical and expected future taxable earnings, and a consideration of available tax-planning strategies, we believe it is more-likely-than-not that we will realize the benefit of the existing deferred tax assets, net of valuation allowances, at December 31, 2018 . Years Ended December 31, (In millions) 2018 2017 2016 Valuation allowances: Beginning of year $ 98.9 62.8 45.7 Expiring tax credits (0.6 ) (0.4 ) (0.4 ) Acquisitions and dispositions (0.7 ) (3.4 ) (0.3 ) Changes in judgment about deferred tax assets (a) — (1.8 ) 2.6 Other changes in deferred tax assets, charged to: Income from continuing operations 6.1 43.9 20.5 Other comprehensive income (loss) (0.3 ) 0.2 0.7 Retained earnings (b) — — 2.5 Foreign currency exchange effects (2.7 ) (2.4 ) (8.5 ) End of year $ 100.7 98.9 62.8 (a) Changes in judgment about valuation allowances are based on a recognition threshold of “more-likely-than-not” of realizing beginning-of-year balances of deferred tax assets. Amounts are recognized in income from continuing operations. (b) In 2016, we recognized $2.5 million in retained earnings as a result of the early adoption of ASU 2016-09.
Net Operating Losses	The tax benefit of net operating loss carryforwards, before valuation allowances, as of December 31, 2018 , was $42.0 million , and expires as follows: (In millions) Federal State Foreign Total Years of expiration 2019-2023 $ — — 5.5 5.5 2024-2028 — 0.6 3.2 3.8 2029 and thereafter — 13.9 0.4 14.3 Unlimited — — 18.4 18.4 $ — 14.5 27.5 42.0

Fair value of options calculation assumptions	The following table provides the terms and weighted-average assumptions used in the Monte Carlo simulation model for the TSR PSUs granted in 2018, 2017 and 2016: Terms and Assumptions Used to Estimate Fair Value 2018 TSR PSUs 2017 TSR PSUs 2016 TSR PSUs Terms of awards: Performance period Jan. 1, 2018 to Jan. 1, 2017 to Jan. 1, 2016 to Dec. 31, 2020 Dec. 31, 2019 Dec. 31, 2018 Weighted-average assumptions used to estimate fair value: Expected dividend yield (a) 0.8 % 0.8 % 1.4 % Expected stock price volatility (b) 29.9 % 30.6 % 29.1 % Risk-free interest rate (c) 2.4 % 1.4 % 0.8 % Contractual term in years 2.9 2.9 2.7 Weighted-average fair value estimates at grant date: In millions $ 3.2 $ 2.0 2.3 Fair value per share $ 79.05 $ 67.81 31.64 (a) TSR is determined assuming that dividends are reinvested. The stock price projection in the Monte Carlo simulation model assumed a 0% dividend yield, which is mathematically equivalent to reinvesting dividends over the performance period. For the valuation of the TSR PSU, because the holders of the awards have no rights to any dividend paid during the vesting period, we applied a dividend yield in the Monte Carlo simulation model to reduce the projected stock price as of the grant date. (b) The expected stock price volatility was calculated on the grant date for the most recent term equivalent to the contractual term in years. (c) The risk-free interest rate on each date of grant is the rate for a zero-coupon U.S. Treasury bill that was commensurate with the grant date contractual term. s. The following table provides the weighted-average assumptions used in the Black-Scholes-Merton option pricing model for the time-based vesting options granted in 2017: Assumptions Used to Estimate Fair Value of Time-Based Options 2017 Assumptions used to estimate fair value: Expected dividend yield (a) 0.7 % Expected stock price volatility (b) 28.9 % Risk-free interest rate (c) 1.7 % Expected term in years (d) 4.5 Weighted-average fair value estimates at grant date: In millions $ 0.1 Fair value per share $ 21.09 (a) The expected dividend yield is the calculated annual yield on Brink's stock at the time of the grant. (b) The expected stock price volatility was calculated at time of the grant after reviewing the historic volatility of our stock using daily close prices. (c) The risk-free interest rate the grant date was the rate for a zero-coupon U.S. Treasury bill that was commensurate with the expected life of 4.5 years. (d) The expected term of the options was based on historical exercise, expiration and post-cancellation behavior. s. The following table provides the term of the performance period and the weighted-average assumptions used in the Monte Carlo simulation model for the performance-based options: Terms and Assumptions Used to Estimate Fair Value of Performance-Based Options Granted 2018 2017 2016 Terms of awards: Performance period for achieving stock price hurdles Three years from Three years from Three years from grant date grant date grant date Assumptions used to estimate fair value: Expected dividend yield (a) 0.8 % 0.8 % 1.3 % Expected stock price volatility (b) 29.3 % 29.3 % 30.9 % Risk-free interest rate (c) 2.6 % 1.8 % 1.1 % Expected term in years (d) 4.5 4.5 4.5 Weighted-average fair value estimates at grant date: In millions $ 7.0 $ 3.6 $ 3.5 Fair value per share $ 16.73 $ 11.97 $ 6.01 (a) Since the holders of the awards have no rights to any dividend paid during the vesting period, we applied a dividend yield in the Monte Carlo simulation model. At each grant date, the dividend yield was calculated based on the most recent annualized dividend payment and Brink's stock price at the date of grant. (b) The expected stock price volatility was calculated on each grant date for the most recent 4.5 year term. (c) The risk-free interest rate on each grant date is the rate for a zero-coupon U.S. Treasury bill that was commensurate with the expected life of 4.5 years. (d) Because we did not have historical exercise behavior for instruments with premiums, we assumed that the exercise of vested options occurred at the mid-point between the three -year vesting date and the six -year contractual term. In the Monte Carlo simulation, at each iteration of forecasted Brink's stock prices, the option was assumed to be exercised at the mid-point of 4.5 years if the stock price hurdle had been achieved. When the hurdle is achieved, the exercise price was then subtracted from the projected stock price, and discounted back to the grant date. In situations where the projected price had not met the hurdle, no value was attributed.
Option Activity	The table below summarizes the activity associated with grants of time-based vesting options: Shares (in thousands) Weighted- Average Exercise Price Per Share Weighted-Average Grant Date Fair Value Per Share Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (a) (in millions) Outstanding at December 31, 2017 40.6 $ 26.74 $ 8.66 Exercised (37.9 ) 22.57 7.77 Outstanding at December 31, 2018 (b) 2.7 $ 84.65 $ 21.09 4.8 $ — Of the above, as of December 31, 2018: Exercisable — $ — — $ — Expected to vest in future periods (c) 2.4 $ 84.65 4.8 $ — (a) The intrinsic value of a stock option is the difference between the market price of the shares underlying the option and the exercise price of the option. The market price at December 31, 2018 was $64.65 and, as a result, there was no intrinsic value associated with any of the options outstanding at December 31, 2018. (b) There were less than 0.1 million shares of exercisable options with a weighted-average exercise price of $22.57 per share at December 31, 2017 and 0.1 million shares of exercisable options with a weighted-average exercise price of $28.80 per share at December 31, 2016. (c) The number of options expected to vest takes into account an estimate of expected forfeitures. The table below summarizes the activity associated with grants of performance-based options: Shares (in thousands) Weighted- Average Exercise Price Per Share Weighted-Average Grant Date Fair Value Per Share Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (a) (in millions) Outstanding at December 31, 2017 879.8 $ 37.95 $ 8.04 Granted 417.6 73.45 16.73 Forfeited or expired (10.4 ) 73.45 17.92 Outstanding at December 31, 2018 (b) 1,287.0 $ 49.18 $ 10.88 4.2 $ 23.5 Of the above, as of December 31, 2018: Exercisable — $ — — $ — Expected to vest in future periods (c) 1,271.2 $ 49.10 4.2 $ 23.3 (a) The intrinsic value of a stock option is the difference between the market price of the shares underlying the option and the exercise price of the option. The market price at December 31, 2018 was $64.65 . (b) Certain performance options were modified in the fourth quarter of 2018 and the resulting impact was not material. The weighted-average grant date fair value per share at December 31, 2018 reflects the inclusion of the modified fair value per share for the modified options. (c) The number of options expected to vest takes into account an estimate of expected forfeitures. We currently have applied a 0% expected forfeiture rate to the majority of the performance-based options.

[1]	We elected to early adopt the provisions of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, in the fourth quarter of 2016 resulting in a cumulative effect adjustment to Retained Earnings for previously unrecognized excess tax benefits. See Note 1 for further discussion of the impacts of this standard.
[2]	Effective January 1, 2018, we adopted the provisions of ASU 2014-09, Revenue From Contracts with Customers, ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, and ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory. We recognized a cumulative effect adjustment to January 1, 2018 retained earnings as a result of adopting each of these standards. See Note 1 for further details of the impact of each standard.

[1]	We elected to early adopt the provisions of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, in the fourth quarter of 2016 resulting in a cumulative effect adjustment to Retained Earnings for previously unrecognized excess tax benefits. See Note 1 for further discussion of the impacts of this standard.
[2]	Effective January 1, 2018, we adopted the provisions of ASU 2014-09, Revenue From Contracts with Customers, ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, and ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory. We recognized a cumulative effect adjustment to January 1, 2018 retained earnings as a result of adopting each of these standards. See Note 1 for further details of the impact of each standard.
