Accounting Policies [Abstract]
Basis of presentation	Basis of presentation Effective February 2017, The Brink’s Company (along with its subsidiaries, “Brink’s” or “we”) implemented changes to its organizational and management structure. As a result of these changes, we now have three operating segments: • North America • South America • Rest of World Our unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial reporting and applicable quarterly reporting regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, the unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes in our Annual Report on Form 10-K for the year ended December 31, 2016 . 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 condensed consolidated financial statements. Actual results could differ materially from these estimates. The most significant estimates are related to goodwill and other long-lived assets, pension and other retirement benefit obligations, legal contingencies and deferred tax assets. Consolidation The condensed 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. 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 under the cost method or, if applicable, as available-for-sale securities. All intercompany accounts and transactions have been eliminated in consolidation. Foreign Currency Translation Our condensed 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 an officially reported 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 (loss). 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. Non-monetary assets and liabilities do not fluctuate with changes in local currency exchange rates to the dollar. Revenues and expenses are translated at rates of exchange in effect during the year. Venezuela The economy in Venezuela has had significant inflation in the last several years. We consolidate our Venezuelan results using our accounting policy for subsidiaries operating in highly inflationary economies. Since 2003, the Venezuelan government has controlled the exchange of local currency into other currencies, including the U.S. dollar, and has required that currency exchanges be made at official rates established by the government instead of allowing open markets to determine currency rates. Different official rates exist for different industries and purposes and the government does not approve all requests to convert bolivars to other currencies. As a result of the restrictions on currency exchange, we have in the past been unable to obtain sufficient U.S. dollars to purchase certain imported supplies and fixed assets to fully operate our business in Venezuela. Consequently, we have occasionally purchased more expensive, bolivar-denominated supplies and fixed assets. There is a risk that official currency exchange mechanisms will be discontinued or will not be accessible when needed in the future, which may prevent us from repatriating dividends or obtaining dollars to operate our Venezuelan operations. Remeasurement rates during 2017 and 2016 . At December 31, 2015, the SIMADI exchange rate used for remeasurement purposes was approximately 199 bolivars to the dollar. In the first quarter of 2016, the Venezuelan government replaced the SIMADI exchange mechanism with the DICOM exchange mechanism and announced that it would allow the DICOM exchange mechanism rate to float freely. At June 30, 2016, the DICOM rate was approximately 628 bolivars to the dollar. Since then, the rate has declined 76% to close at approximately 2,640 bolivars to the dollar at June 30, 2017 . We have received only minimal U.S. dollars through this exchange mechanism. In the first six months of 2017, we recognized a $8.4 million pretax remeasurement loss. The after-tax effect of this loss attributable to noncontrolling interest was $0.9 million . In the first six months of 2016, we recognized a $4.6 million pretax remeasurement loss. However, the after-tax effect of this loss attributable to noncontrolling interest was income of $2.6 million . Items related to our Venezuelan operations are as follows: • Our investment in our Venezuelan operations on an equity-method basis was $20.1 million at June 30, 2017 and $19.2 million at December 31, 2016 . • Our Venezuelan operations had net payables to other Brink's affiliates of $2.5 million at June 30, 2017 and $6.1 million at December 31, 2016 . • Our Venezuelan operations had net non-monetary assets of $20.1 million at June 30, 2017 and $17.6 million at December 31, 2016 . • Our bolivar-denominated net monetary net assets were $2.7 million (including $5.2 million of cash and cash equivalents) at June 30, 2017 and $1.4 million (including $6.8 million of cash and cash equivalents) at December 31, 2016 . • Accumulated other comprehensive losses attributable to Brink’s shareholders related to our Venezuelan operations were $114.2 million at June 30, 2017 and $114.7 million at December 31, 2016 . Argentina The economy in Argentina has had significant inflation in recent years. Through June 30, 2017 , Argentina was not designated as a highly inflationary economy for accounting purposes. We will continue to monitor developments in Argentina at each reporting date to determine whether we should consolidate Brink's Argentina results using our accounting policy for subsidiaries operating in highly inflationary economies. We use the official exchange rate to translate the Brink's Argentina balance sheet and income statement. At June 30, 2017 , the official exchange rate was approximately 16.6 Argentine pesos to the U.S. dollar. At June 30, 2017 , we had cash and short-term investments denominated in Argentine pesos of $28.7 million . We expect to use a significant portion of the cash and short-term investments to fund a business acquisition in Argentina (see Note 13). 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 were included in items not allocated to segments and were 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 were treated similarly to the Republic of Ireland. International shipments to and from Ireland continue to be provided through Brink’s Global Services ("BGS"). Acquisitions In the first six months of 2017, we completed three business acquisitions in Brazil, Chile and the U.S. which are not material to our consolidated financial statements. The aggregate purchase price, net of cash acquired, for these three acquisitions was approximately $65 million . New Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue From Contracts with Customers , a new standard related to revenue recognition, which requires an entity to recognize an amount of revenue to which it expects to be entitled for the transfer of promised goods and services to customers. The new standard will replace most of the existing revenue recognition standards in U.S. GAAP. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of this new standard to January 1, 2018. Subsequently, the FASB has continued to refine the standard and has issued several amendments. The most likely effects of the new standard for us will be associated with variable consideration and capitalization of costs to obtain contracts, such as sales commissions. However, we do not expect a material impact on our future consolidated statements of operations or consolidated balance sheets. The new guidance will result in expanded disclosures regarding our various performance obligations, revenue disaggregation and contractual rights. We plan to use the modified retrospective method to adopt the new standard. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash , which requires entities to include restricted cash and restricted cash equivalent balances with cash and cash equivalent balances in the statement of cash flows. ASU 2016-18 will impact the presentation of our statement of cash flows, will be effective January 1, 2018, and requires using a retrospective transition method to adopt the standard. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which will require the recognition of assets and liabilities by lessees for certain leases classified as operating leases under current accounting guidance and also requires expanded disclosures regarding leasing activities. ASU 2016-02 will be effective January 1, 2019 and we are required to use the modified retrospective method to adopt the new standard. We are assessing the potential impact of the standard on financial reporting. 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 must be 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 have 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 statement of operations or the classification of excess tax benefits in the statement of cash flows. In the first six months of 2017, the accounting under this ASU resulted in the recognition of $5.5 million in excess tax benefits. 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 condensed consolidated statements of operations have been updated to reflect this guidance. The adoption of this ASU resulted in a change in certain previously reported amounts in the first half of 2016 condensed consolidated statement of operations. Cost of revenues decreased $16.5 million , selling, general and administrative expenses decreased $3.3 million and operating profit as well as interest and other income (expense) increased $19.8 million compared to previously reported first half of 2016 amounts. The early adoption of this ASU had no impact on the previously reported loss from continuing operations or net loss for the prior year periods.

Segment Reporting [Abstract]
Segment information	Segment information The Brink’s Company offers transportation and logistics management services for cash and valuables throughout the world. These services include: • Cash-in-Transit (“CIT”) Services – armored vehicle transportation of valuables • ATM Services – replenishing and maintaining customers’ automated teller machines; providing network infrastructure services • Global Services – secure international transportation of valuables • Cash Management Services ◦ Currency and coin counting and sorting; deposit preparation and reconciliations; other cash management services ◦ Safe and safe control device installation and servicing (including our patented CompuSafe ® service) ◦ Check and cash processing services for banking customers (“Virtual Vault Services”) ◦ Check imaging services for banking customers • Payment Services – bill payment and processing services on behalf of utility companies and other billers at any of our Brink’s or Brink’s-operated payment locations in Latin America and Brink’s Money™ general purpose reloadable prepaid cards and payroll cards in the U.S. • Guarding Services – protection of airports, offices, and certain other locations in Europe and Brazil with or without electronic surveillance, access control, fire prevention and highly trained patrolling personnel 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 our operating segments 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. Results from Venezuela operations are also excluded from our segment results due to management’s inability to allocate, generate or redeploy resources in-country or globally. We also exclude certain costs, gains and losses related to acquisitions and dispositions that are special in nature. For additional information about these reconciling items see "Other Items Not Allocated to Segment" on pages 32-33. During the first quarter of 2017, we implemented changes to our organizational and management structure that resulted in changes to our operating segments for financial reporting purposes. Through the fiscal year ended December 31, 2016, our business was reported in nine operating segments: U.S., France, Mexico, Brazil, Canada, Latin America, EMEA, Asia and Payment Services. Changes in our management reporting structure during the first quarter of 2017 required us to conduct an assessment in accordance with ASC Topic 280, Segment Reporting , to determine our operating segments. As a result of this assessment, we now have the following operating segments: • North America • South America • Rest of World (ROW). The following table summarizes our revenues and segment profit for each of our reportable segments and reconciles these amounts to consolidated revenues and operating profit: Revenues Operating Profit Three Months Ended June 30, Three Months Ended June 30, (In millions) 2017 2016 2017 2016 Reportable Segments: North America $ 311.0 300.8 $ 16.7 3.8 South America 204.6 170.1 35.7 21.3 Rest of World 244.0 245.6 25.1 27.5 Total reportable segments 759.6 716.5 77.5 52.6 Reconciling Items: Corporate expenses: General, administrative and other expenses — — (18.3 ) (16.1 ) Foreign currency transaction gains (losses) — — 1.4 1.4 Reconciliation of segment policies to GAAP — — (0.9 ) 1.3 Other items not allocated to segments: Venezuela operations 46.3 21.5 (4.5 ) 1.6 Reorganization and Restructuring — — (5.6 ) (2.1 ) Acquisitions and dispositions — 1.5 (1.3 ) (6.5 ) Total $ 805.9 739.5 $ 48.3 32.2 Revenues Operating Profit Six Months Ended June 30, Six Months Ended June 30, (In millions) 2017 2016 2017 2016 Reportable Segments: North America $ 615.6 593.5 $ 26.9 7.5 South America 406.8 327.1 74.4 45.0 Rest of World 477.5 484.8 50.4 45.9 Total reportable segments 1,499.9 1,405.4 151.7 98.4 Reconciling Items: Corporate expenses: General, administrative and other expenses — — (37.5 ) (33.7 ) Foreign currency transaction gains (losses) — — 0.2 2.7 Reconciliation of segment policies to GAAP — — (1.8 ) 4.5 Other items not allocated to segments: Venezuela operations 94.4 53.6 16.6 4.3 Reorganization and Restructuring — — (9.7 ) (8.1 ) Acquisitions and dispositions — 2.3 (0.3 ) (12.4 ) Total $ 1,594.3 1,461.3 $ 119.2 55.7 See "Other Items Not Allocated to Segment" on pages 32 – 33 for explanations of each of the other items not allocated to segments.

The other items that cause the rate to be higher than the U.S. statutory rate include the seasonality of book losses for which no tax benefit can be recorded, nondeductible expenses in Mexico, taxes on cross border payments and the characterization of a French business tax as an income tax, partially offset by the geographical mix of earnings and a French income tax credit. 2016 Compared to U.S. Statutory Rate The effective income tax rate on continuing operations in the first six months of 2016 was greater than the 35% U.S. statutory tax rate primarily due to the significant losses related to operations in the Republic of Ireland, for which no tax benefit can be recorded, and the nondeductible expenses resulting from the currency devaluation in Venezuela in the first six months. The other items that cause the rate to be higher than the U.S. statutory rate include the seasonality of book losses for which no tax benefit can be recorded, nondeductible expenses in Mexico, taxes on undistributed earnings and the characterization of a French business tax as an income tax, partially offset by the geographical mix of earnings and a French income tax credit.

Fair Value Disclosures [Abstract]
Fair value of financial instruments	Fair value of financial instruments Investments in Trading Securities and Available-for-sale Securities We have investments in mutual funds designated as trading securities and as available-for-sale securities that are carried at fair value in the financial statements. For these investments, fair value was estimated based on quoted market prices categorized as a Level 1 valuation. Fixed-Rate Debt The fair value and carrying value of our fixed-rate debt are as follows: (In millions) June 30, 2017 December 31, 2016 Unsecured notes issued in a private placement Carrying value $ 78.6 85.7 Fair value 80.9 88.2 The fair value estimate of our unsecured private-placement notes is based on the present value of future cash flows, discounted at rates for similar instruments at the respective measurement dates, 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 June 30, 2017 , the notional value of our shorter term outstanding foreign currency forward and swap contracts was $32.4 million , with average maturities of approximately one month. These shorter term foreign currency forward and swap contracts primarily offset exposures in the British pound, the euro and the new Taiwan dollar and are not designated as hedges for accounting purposes. At June 30, 2017 , the fair value of these shorter term foreign currency contracts was not significant. In 2013, we entered into a longer term cross-currency swap to hedge against the change in value of a long-term intercompany loan denominated in Brazilian real. This longer term contract is designated as a cash flow hedge for accounting purposes. At June 30, 2017 , the notional value of this contract was $4.7 million with a remaining weighted-average maturity of 0.3 years . At June 30, 2017 , the fair value of this longer term swap contract was an asset of $1.9 million , which is included in prepaid expenses and other on the condensed consolidated balance sheet. In the first quarter of 2016, we entered into two interest rate swaps with a total notional value of $40 million with a remaining weighted-average maturity of 2.0 years . These swaps were entered into to hedge cash flow risk associated with changes in variable interest rates and are designated as cash flow hedges for accounting purposes. At June 30, 2017 , the fair value of these interest rates swaps was a net asset of $0.7 million , which is included in other assets on the condensed consolidated balance sheet. The fair values of these forward and swap contracts are determined using Level 2 valuation techniques and are based on the present value of net future cash payments and receipts. 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 the first six months of 2017 .

As of June 30, 2017 , $24 million was outstanding. Long-Term Debt Revolving Facility We have a $525 million unsecured multi-currency revolving bank credit facility (the “Revolving Facility”) that matures in March 2020 . The Revolving Facility’s interest rate is based on LIBOR plus a margin or an alternate base rate plus a margin. The Revolving Facility allows us to borrow funds or issue letters of credit (or otherwise satisfy credit needs) on a revolving basis over the term of the facility. As of June 30, 2017 , $361 million was available under the Revolving Facility. Amounts outstanding under the Revolving Facility, as of June 30, 2017 , were denominated primarily in U.S. dollars and to a lesser extent in euros. The margin on LIBOR borrowings under the Revolving Facility, which can range from 1.0% to 1.70% depending on either our credit rating or leverage ratio as defined within the Revolving Facility, was 1.30% at June 30, 2017 . The margin on alternate base rate borrowings under the Revolving Facility ranges from 0.0% to 0.70% . We also pay an annual facility fee on the Revolving Facility based on our credit rating or the leverage ratio. The facility fee can range from 0.125% to 0.30% and was 0.20% at June 30, 2017 . Private Placement Notes As of June 30, 2017 , we had $79 million principal amount of unsecured notes outstanding, which were issued through a private placement debt transaction (the “Notes”).

Annual principal payments under the series A notes began in January 2015 and continue through maturity. The series B notes are due in January 2021 . Term Loan We entered into a $75 million unsecured term loan in March 2015 . Interest on this loan is based on LIBOR plus a margin of 1.75% .

Multi-currency Revolving and Other Facilities As of June 30, 2017 , we had one $20 million unsecured multi-currency revolving bank credit facility, of which $11 million was available. As of June 30, 2017 , we had funded debt of $4 million and undrawn letters of credit and guarantees of $5 million issued under the multi-currency revolving bank credit facility, which expires in March 2019 . Interest on this facility is based on LIBOR plus a margin, which ranges from 1.0% to 1.7% . We also have the ability to borrow from other banks, at the banks' discretion, under short-term uncommitted agreements. Various foreign subsidiaries maintain other lines of credit and overdraft facilities with a number of banks. Letter of Credit Facilities We have a $40 million uncommitted letter of credit facility that expires in May 2018 . As of June 30, 2017 , $5 million was utilized. We have two unsecured letter of credit facilities totaling $94 million , of which approximately $39 million was available at June 30, 2017 .

A $40 million facility expires in December 2018 and a $54 million facility expires in December 2019 . The Revolving Facility and the multi-currency revolving credit facilities are also used for issuance of letters of credit and bank guarantees. The Revolving Facility, the Notes, the unsecured multi-currency revolving bank credit facility, the uncommitted credit facilities, the letter of credit facilities and the unsecured term loan contain certain subsidiary guarantees and various financial and other covenants. The financial covenants, among other things, limit our total indebtedness, restrict certain payments to shareholders, limit priority debt, limit asset sales, limit the use of proceeds from asset sales, provide for a maximum leverage ratio and provide for minimum coverage of interest costs. These agreements do not provide for the acceleration of payments should our credit rating be reduced. 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 June 30, 2017 .

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 granted share-based awards to employees under the 2005 Equity Incentive Plan ("2005 Plan"), the 2013 Equity Incentive Plan ("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 under the 2013 Plan and under the 2005 Plan remain outstanding. We have granted deferred stock units 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. Outstanding awards at June 30, 2017 , include performance share units, market 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 employee and director awards considered equity grants, compensation expense is recognized from the award or grant date to the earlier of the retirement-eligible date or the vesting date. In February 2016, the Compensation and Benefits Committee of the Board of Directors modified the terms of performance share units originally awarded or granted in 2013, 2014 and 2015 to reflect the impact of removing Venezuela operations from the Company’s segment results beginning in 2015. For each of the affected performance share units, consolidated results for 2015 and each subsequent year within the respective performance period was or will be adjusted to reflect Venezuela results at the amount originally projected in the applicable performance target. No incremental compensation cost associated with the modification has been recognized as the modified goal was and is expected to be more difficult to achieve and, in accordance with FASB ASC Topic 718, Compensation - Stock Compensation , we continue to recognize expense as calculated using the original performance goal. Compensation expenses are classified as selling, general and administrative expenses in the condensed consolidated statements of operations. Compensation expenses for the share-based awards were as follows: Compensation Expense Compensation Expense Three Months Ended June 30, Six Months Ended June 30, (in millions) 2017 2016 2017 2016 Performance Share Units $ 1.9 1.0 $ 4.5 2.3 Market Share Units — — 0.1 0.2 Restricted Stock Units 1.2 0.9 2.4 2.0 Deferred Stock Units and fees paid in stock 0.3 0.1 0.5 0.3 Stock Options 0.6 0.1 1.0 0.1 Share-based payment expense 4.0 2.1 8.5 4.9 Income tax benefit (1.5 ) (0.7 ) (3.1 ) (1.7 ) Share-based payment expense, net of tax $ 2.5 1.4 $ 5.4 3.2 Performance-Based Stock Options In 2017 and 2016, we granted performance-based stock options that 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 performance-based options at the grant date using a Monte Carlo simulation model. The following table summarizes performance-based stock option activity during the first six months of 2017 : Shares (in thousands) Weighted-Average Grant-Date Fair Value Outstanding balance as of December 31, 2016 580.9 $ 6.01 Granted 298.9 11.97 Forfeited — — Exercised — — Outstanding balance as of June 30, 2017 879.8 $ 8.04 Restricted Stock Units (“RSUs”) We granted RSUs that contain only a service condition.

In 2017 and 2016, we granted Internal Metric PSUs ("IM PSUs") and Total Shareholder Return PSUs ("TSR PSUs"). 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. For the IM PSUs granted in 2017, the performance period is from January 1, 2017 to December 31, 2019. TSR PSUs contain a market condition as well as a service condition. We measure the fair value of PSUs containing a market condition at the grant date using a Monte Carlo simulation model. For the TSR PSUs granted in 2017, the performance period is from January 1, 2017 to December 31, 2019. The following table summarizes all PSU activity during the first six months of 2017 : Shares (in thousands) Weighted-Average Grant-Date Fair Value Nonvested balance as of December 31, 2016 603.2 $ 28.02 Granted 217.1 53.75 Forfeited (14.0 ) 29.14 Vested (a) (134.3 ) 24.39 Nonvested balance as of June 30, 2017 672.0 $ 37.04 (a) The vested PSUs presented are based on the target amount of the award.

Market Share Units ("MSUs”) Prior to 2016, we granted MSUs that contain a market condition as well as a service condition. We measure the fair value of MSUs using a Monte Carlo simulation model. The following table summarizes all MSU activity during the first six months of 2017 : Shares (in thousands) Weighted-Average Grant-Date Fair Value Nonvested balance as of December 31, 2016 141.7 $ 27.02 Granted — — Forfeited — — Vested (a) (67.5 ) 23.34 Nonvested balance as of June 30, 2017 74.2 $ 30.37 (a) The vested MSUs presented are based on the target amount of the award. In accordance with the terms of the underlying award agreements or plan provisions, the actual shares earned and distributed for the performance period ended December 31, 2016 were 81.8 . No additional compensation expense was required to be recognized for the additional shares distributed, as the market condition was included in the $23.34 grant date fair value. Deferred Stock Units ("DSUs") We granted DSUs to our independent directors. We measure the fair value of DSUs at the grant date, based on the price of Brink's stock, adjusted for a discount for dividends not received or accrued during the vesting period. Grants of DSUs vest and 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. The following table summarizes all DSU activity during the first six months of 2017 : Shares (in thousands) Weighted-Average Grant-Date Fair Value Nonvested balance as of December 31, 2016 29.7 $ 29.41 Granted 12.7 60.80 Forfeited (3.7 ) 29.35 Vested (26.0 ) 29.42 Nonvested balance as of June 30, 2017 12.7 $ 60.80

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 June 30, 2017 , we held $87.7 million of restricted cash ( $26.1 million represented short-term borrowings, $58.2 million represented restricted cash held for customers, and $3.4 million represented deposit liabilities). At December 31, 2016 , we held $55.5 million of restricted cash ( $22.3 million represented short-term borrowings and $33.2 million represented restricted cash held for customers).

Commitments and Contingencies Disclosure [Abstract]
Contingent matters	Contingent matters During the fourth quarter of 2015, we became aware of an investigation initiated by COFECE (the Mexican antitrust agency) related to potential anti-competitive practices among competitors in the cash logistics industry in Mexico (the industry in which Brink’s Mexican subsidiary, SERPAPROSA, is active). Because no legal proceedings have been initiated against SERPAPROSA, we cannot estimate the probability of loss or any range of estimate of possible loss at this time. It is possible that SERPAPROSA could become the subject of legal or administrative claims or proceedings, however, that could result in a loss that could be material to the Company’s results in a future period. On March 21, 2016, The Bruce McDonald Holding Company, et al., filed a lawsuit in Circuit Court of Logan County, West Virginia against Addington, Inc. (“Addington”) and The Brink’s Company related to an Agreement of Lease dated September 19, 1978, between the Plaintiffs and Addington. Plaintiffs seek declaratory judgment and unspecified damages related to allegations that Addington failed to mine coal on the property leased from the Plaintiffs and failed to pay correct minimum royalties to the Plaintiffs. The Company denies the allegations asserted by the Plaintiffs, is vigorously defending itself in this matter, and has filed a counterclaim against the Plaintiffs related to Plaintiffs’ failure to consent to the assignment and subleasing the leasehold to others. Due to numerous uncertain and unresolved factors presented in this case, it is not possible to estimate a range of loss at this time and, accordingly, no accrual has been recorded in the Company’s financial statements. 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 the ultimate disposition of any of the lawsuits currently pending against the Company should have a material adverse effect on our liquidity, financial position or results of operations.

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. We recognized an additional $8.0 million in the first six months of 2017 under this restructuring for additional costs related to severance, a benefit program termination and asset-related adjustments. Severance actions are expected to reduce our global workforce by 800 to 900 positions. We expect that the 2016 restructuring will result in $8 to $12 million in 2017 cost savings. We expect to incur additional costs between $14 and $18 million in future periods, primarily severance costs. 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, 2017 $ — 7.0 0.6 — 7.6 Expense (benefit) 2.1 3.7 — 2.2 8.0 Payments and utilization (2.1 ) (6.9 ) 0.1 (1.9 ) (10.8 ) Foreign currency exchange effects — 0.1 — — 0.1 Balance as of June 30, 2017 $ — 3.9 0.7 0.3 4.9 Executive Leadership and Board of Directors Restructuring In the fourth quarter of 2015, we recognized $1.8 million in costs related to the restructuring of executive leadership and the Board of Directors, which was announced in January 2016. We also recognized an additional $3.8 million in charges, primarily severance costs, in the first half of 2016. 2015 Reorganization and Restructuring Brink's initiated a global restructuring of its business in the third quarter of 2015. We recognized $11.6 million in related 2015 costs related to employee severance, contract terminations, and property impairment. We recognized an additional $4.4 million in the first six months of 2016 related to this restructuring for additional severance costs and contract 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 .

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events In July 2017 , we acquired 100% of the capital stock of Maco Transportadora de Caudales S.A. ("Maco") for approximately $209 million , with the final purchase price subject to post-closing adjustments and foreign exchange translation. Maco offers cash-in-transit and money processing operations in Argentina and will be integrated with our existing Argentina business. Over the last 12 months, Maco generated revenue of approximately $90 million . The provisional purchase accounting for this acquisition has not yet been completed. We also announced in July 2017 that we have signed an exclusive agreement to negotiate the purchase of the Temis group of companies ("Temis") in France for approximately $71 million , subject to post-closing adjustments and foreign exchange translation. Temis provides cash-in-transit, money processing and ATM services and has generated revenue of approximately $50 million over the last 12 months. The acquisition is subject to customary closing conditions and is expected to close in the fourth quarter of 2017.

Accounting Policies [Abstract]
Use of Estimates	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 condensed consolidated financial statements. Actual results could differ materially from these estimates. The most significant estimates are related to goodwill and other long-lived assets, pension and other retirement benefit obligations, legal contingencies and deferred tax assets.
Consolidation	Consolidation The condensed 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. 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 under the cost method or, if applicable, as available-for-sale securities. All intercompany accounts and transactions have been eliminated in consolidation.
Foreign Currency Translation	Foreign Currency Translation Our condensed 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 an officially reported 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 (loss). 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. Non-monetary assets and liabilities do not fluctuate with changes in local currency exchange rates to the dollar. Revenues and expenses are translated at rates of exchange in effect during the year. Venezuela The economy in Venezuela has had significant inflation in the last several years. We consolidate our Venezuelan results using our accounting policy for subsidiaries operating in highly inflationary economies.
New Accounting Standards	New Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue From Contracts with Customers , a new standard related to revenue recognition, which requires an entity to recognize an amount of revenue to which it expects to be entitled for the transfer of promised goods and services to customers. The new standard will replace most of the existing revenue recognition standards in U.S. GAAP. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of this new standard to January 1, 2018. Subsequently, the FASB has continued to refine the standard and has issued several amendments. The most likely effects of the new standard for us will be associated with variable consideration and capitalization of costs to obtain contracts, such as sales commissions. However, we do not expect a material impact on our future consolidated statements of operations or consolidated balance sheets. The new guidance will result in expanded disclosures regarding our various performance obligations, revenue disaggregation and contractual rights. We plan to use the modified retrospective method to adopt the new standard. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash , which requires entities to include restricted cash and restricted cash equivalent balances with cash and cash equivalent balances in the statement of cash flows. ASU 2016-18 will impact the presentation of our statement of cash flows, will be effective January 1, 2018, and requires using a retrospective transition method to adopt the standard. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which will require the recognition of assets and liabilities by lessees for certain leases classified as operating leases under current accounting guidance and also requires expanded disclosures regarding leasing activities. ASU 2016-02 will be effective January 1, 2019 and we are required to use the modified retrospective method to adopt the new standard. We are assessing the potential impact of the standard on financial reporting. 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 must be 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 have 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 statement of operations or the classification of excess tax benefits in the statement of cash flows. In the first six months of 2017, the accounting under this ASU resulted in the recognition of $5.5 million in excess tax benefits. 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 condensed consolidated statements of operations have been updated to reflect this guidance. The adoption of this ASU resulted in a change in certain previously reported amounts in the first half of 2016 condensed consolidated statement of operations. Cost of revenues decreased $16.5 million , selling, general and administrative expenses decreased $3.3 million and operating profit as well as interest and other income (expense) increased $19.8 million compared to previously reported first half of 2016 amounts. The early adoption of this ASU had no impact on the previously reported loss from continuing operations or net loss for the prior year periods.
