Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Description of Business OUTFRONT Media Inc. (the “Company”) and its subsidiaries (collectively, “we,” “us” or “our”) is a real estate investment trust (“REIT”), which provides advertising space (“displays”) on out-of-home advertising structures and sites in the United States (the “U.S.”) and Canada. Our inventory consists of billboard displays, which are primarily located on the most heavily traveled highways and roadways in top Nielsen Designated Market Areas (“DMAs”), and transit advertising displays operated under exclusive multi-year contracts with municipalities in large cities across the U.S. and Canada. We also have marketing and multimedia rights agreements with colleges, universities and other educational institutions, which entitle us to operate on-campus advertising displays, as well as manage marketing opportunities, media rights and experiential entertainment at sports events. In total, we have displays in all of the 25 largest markets in the U.S. and approximately 140 markets across the U.S. and Canada. We manage our operations through three operating segments—(1) U.S. Billboard and Transit, which is included in our U.S. Media reportable segment, (2) International and (3) Sports Marketing. On April 1, 2016, we sold all of our equity interests in certain of our subsidiaries (the “Disposition”), which held all of the assets of our outdoor advertising business in Latin America (see Note 13. Acquisitions and Dispositions : Dispositions to the Consolidated Financial Statements). The operating results of our outdoor advertising business in Latin America through April 1, 2016, are included in our Consolidated Financial Statements for 2016. Basis of Presentation and Use of Estimates The accompanying consolidated financial statements have been prepared pursuant to the rules of the Securities and Exchange Commission (the “SEC”). In the opinion of our management, the accompanying financial statements reflect all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation of our financial position, results of operations and cash flows for the years presented. Certain previously reported amounts have been reclassified to conform with the current 2018 presentation.

Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation— The consolidated financial statements include the accounts of OUTFRONT Media Inc. and all of its subsidiaries in which a controlling interest is maintained. Controlling interest is determined by majority ownership interest and the absence of substantive third-party participating rights. Investments over which we have a significant influence or ownership of more than 20% but less than or equal to 50% , without a controlling interest, are accounted for under the equity method. Investments of 20% or less, over which we have no significant influence, that do not have a readily determinable fair value, are measured at cost less impairment, if any. Intercompany transactions have been eliminated. Cash and Cash Equivalents and Restricted Cash —Cash and cash equivalents consist of cash on hand and short-term (maturities of three months or less at the date of purchase) highly liquid investments. We classify cash balances that are legally restricted pursuant to contractual arrangements as restricted cash. Receivables —Receivables consist primarily of trade receivables from customers, net of advertising agency commissions, and are stated net of an allowance for doubtful accounts. The provision for doubtful accounts is estimated based on historical bad debt experience, the aging of accounts receivable, industry trends and economic indicators, as well as recent payment history for specific customers. New York Metropolitan Transportation Authority (the “MTA”) Agreement— Under the MTA Agreement, as title of the various digital displays we are obligated to deploy transfers to the MTA on installation, the cost of deploying these screens throughout the transit system does not represent our property and equipment. The portion of deployment costs expected to be reimbursed from transit franchise fees that would otherwise be payable to the MTA are recorded as Prepaid MTA equipment deployment costs on the Consolidated Statement of Financial Position and charged to operating expenses as advertising revenue is generated. The short-term portion of Prepaid MTA equipment deployment costs represents the costs that we expect to recover from the MTA in the next twelve months. The portion of deployment costs expected to be reimbursed from advertising revenues that would otherwise be retained by us under the contract are recorded as Intangible assets on the Consolidated Statement of Financial Position and charged to amortization expense on a straight line basis over the contract period. Property and Equipment —Property and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives as follows: Buildings and improvements 20 to 40 years Advertising structures 5 to 20 years Furniture, equipment and other 3 to 10 years For advertising structures associated with a contract, the assets are depreciated over the shorter of the contract term or useful life. Maintenance and repair costs to maintain property and equipment in their original operating condition are charged to expense as incurred. Improvements or additions that extend the useful life of the assets are capitalized. When an asset is retired or otherwise disposed of, the associated cost and accumulated depreciation are removed and the resulting gain or loss is recognized. Construction in progress includes all costs capitalized related to projects, primarily related to in-process digital conversion and development, which have yet to be placed in service. Business Combinations and Asset Acquisitions —We routinely acquire out-of-home advertising assets, including advertising structures, permits and leasehold agreements. We determine the accounting for these transactions by first evaluating whether the assets acquired and liabilities assumed, if any, constitute a business using the guidelines in the Financial Accounting Standards Board (“FASB”) guidance for business combinations. If the assets acquired and liabilities assumed constitute a business, the purchase price is allocated to the tangible and identifiable intangible net assets acquired based on their estimated fair values with the excess of the purchase price over those estimated fair values recorded as goodwill. If the acquired assets do not constitute a business, we allocate the purchase price to the individual tangible and intangible assets acquired based on their relative fair values. Impairment of Long-Lived Assets— Long-lived assets are assessed for impairment whenever there is an indication that the carrying amount of the asset may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted cash flows generated by those assets to the respective asset’s carrying value. The amount of impairment loss, if any, will be measured by the difference between the net carrying value and the estimated fair value of the asset and recognized as a non-cash charge. Long-lived assets held for sale are required to be measured at the lower of their carrying value (including unrecognized foreign currency translation adjustment losses) or fair value less cost to sell. Goodwill and Intangible Assets— Goodwill is allocated to various reporting units. Goodwill is not amortized but is tested qualitatively and/or quantitatively at the reporting-unit level annually for impairment on October 31 of each year and between annual tests if events occur or circumstances change that would more likely than not reduce the fair value below its carrying amount. A qualitative test assesses macroeconomic conditions, industry and market conditions, cost factors, overall financial performance and other relevant entity specific events, as well as events affecting a reporting unit. If after the qualitative assessment, we determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we perform a quantitative assessment. We may also choose to only perform a quantitative assessment. We compute the estimated fair value of each reporting unit for which we perform a quantitative assessment by adding the present value of the estimated annual cash flows over a discrete projection period to the residual value of the business at the end of the projection period. This technique requires us to use significant estimates and assumptions such as growth rates, operating margins, capital expenditures and discount rates. The estimated growth rates, operating margins and capital expenditures for the projection period are based on our internal forecasts of future performance as well as historical trends. The residual value is estimated based on a perpetual nominal growth rate, which is based on projected long-range inflation and long-term industry projections. The discount rates are determined based on the weighted average cost of capital of comparable entities. There can be no assurance that these estimates and assumptions will prove to be an accurate prediction of the future, and a downward revision of these estimates and/or assumptions would decrease the fair values of our reporting units, which could result in additional impairment charges in the future. If the carrying value of a reporting unit is greater than its fair value, a goodwill impairment charge will be recorded as a non-cash charge for the difference up to the carrying value of the goodwill. The loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Intangible assets, which primarily consist of acquired permits and leasehold agreements and franchise agreements, are amortized by the straight-line method over their estimated useful lives, which range from five to 40 years . Hedging Activities —As of December 31, 2018, we utilized interest rate cash flow swap agreements to effectively convert a portion of our LIBOR-based variable rate debt to a fixed rate. These interest rate swaps have been designated and qualify as cash flow hedges and, as a result, changes in the fair value of these swaps are recorded in Other comprehensive income (loss) before taxes on the Consolidated Statements of Comprehensive Income. Revenue Recognition —We derive Revenues from the following sources: (i) billboard displays, (ii) transit displays, and (iii) other. Billboard display revenues are derived from providing advertising space to customers on our physical billboards or other outdoor structures. We generally (i) own the physical structures on which we display advertising copy for our customers, (ii) hold the legal permits to display advertising thereon, and (iii) lease the underlying sites. Billboard display revenues are recognized under the lease accounting standard as rental income on a straight-line basis over the customer lease term. Transit display revenues are derived from agreements with municipalities and transit operators, which entitle us to operate advertising displays within their transit systems, including on the interior and exterior of rail and subway cars and buses, as well as on benches, transit shelters, street kiosks and transit platforms. Transit display contracts typically require the installation and delivery of multiple advertising displays, for which locations are not specifically identified. Installation services are highly interdependent with the provision of advertising space, and therefore the installation and display of advertising is recognized as a single performance obligation. Transit display revenues are recognized based on the level of units displayed in proportion to the total units to be displayed over the contract period. Other revenues are derived primarily from (i) providing print production services for advertisements to be displayed on our billboards or other outdoor sites, or on displays that we operate within transit systems, and (ii) revenues from marketing and multimedia rights agreements with colleges, universities and other educational institutions, which entitle us to operate on-campus advertising displays, as well as manage marketing opportunities, media rights and experiential entertainment at sports events. Print production services are not interrelated with the provision of advertising space and are considered a distinct performance obligation. Production revenue is recognized over the production period, which is typically very short in duration. Revenues from our Sports Marketing operating segment are principally derived from advertising and marketing arrangements and are recognized over the contract period. Our billboard display and transit display contracts with customers range from four weeks to one year and billing commences at the beginning of the contract term, with payment generally due within 30 days of billing. For the majority of our contracts, transaction prices are explicitly stated. Any contracts with transaction prices that contain multiple performance obligations, are allocated primarily based on a relative standalone selling price basis. Deferred revenues primarily consist of revenues paid in advance of being earned. Concentration of Credit Risk— In the opinion of management, credit risk is limited due to the large number of customers and advertising agencies utilized. We perform credit evaluations on our customers and agencies and believe that the allowances for doubtful accounts are adequate. Billboard Property Lease and Transit Franchise Expenses —Our billboards are primarily located on leased real property. Lease agreements are negotiated for varying terms ranging from one month to multiple years, most of which provide renewal options. Lease costs consist of a fixed monthly amount and certain lease agreements also include contingent rent based on the revenues we generate from the leased site. Property leases are generally paid in advance for periods ranging from one to twelve months . The fixed component of lease costs is expensed evenly over the non-cancellable contract term, and contingent rent is expensed as incurred when the related revenues are recognized. Transit franchise agreements generally provide for payment to the municipality or transit operator of the greater of a percentage of the revenues that we generate under the related transit contract and a specified guaranteed minimum payment. The costs which are determined based on a percentage of revenues are expensed as incurred when the related revenues are recognized, and the minimum guarantee is expensed over the contract term. Direct Lease Acquisition Costs— Variable commissions directly associated with billboard revenues are amortized on a straight-line basis over the related customer lease term, which generally ranges from four weeks to one year. Amortization of direct lease acquisition costs is presented within Amortization expense in the accompanying Consolidated Statements of Operations. Foreign Currency Translation and Transactions— The assets and liabilities of foreign subsidiaries are translated at exchange rates in effect at the balance sheet date, while results of operations are translated at average exchange rates for the respective periods. Any gain or loss on translation is included within other comprehensive income (loss) and Accumulated other comprehensive loss on our Consolidated Statement of Financial Position. Foreign currency transaction gains and losses are included in Other income (expense), net, on the Consolidated Statements of Operations. Income Taxes— As of July 17, 2014, we began operating as a REIT. Accordingly, we generally will not be subject to U.S. federal income tax on our REIT taxable income that we distribute to our stockholders. We have elected to treat our subsidiaries that participate in certain non-REIT qualifying activities, and certain of our foreign subsidiaries, as taxable REIT subsidiaries (“TRSs”). As such, the taxable income of our TRSs will be subject to federal, state and foreign income taxation at regular corporate rates. Income taxes are accounted for under the asset and liability method of accounting. Deferred income tax assets and liabilities are recognized for the estimated future tax effects of temporary differences between the financial statement carrying amounts and their respective tax basis. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax assets will not be realized. We have applied the FASB’s guidance relating to uncertainty in income taxes recognized. Under this guidance we may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The tax benefits recognized from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The guidance on accounting for uncertainty in income taxes also provides guidance on de-recognition, classification, interest and penalties on income taxes, and accounting in interim periods. Asset Retirement Obligation —An asset retirement obligation is established for the estimated future obligation, upon termination or non-renewal of a lease, associated with removing structures from the leased property and, when required by the contract, the cost to return the leased property to its original condition. These obligations are recorded at their present value in the period in which the liability is incurred and are capitalized as part of the related assets’ carrying value. Accretion of the liability is recognized in selling, general and administrative expenses and the capitalized cost is depreciated over the expected useful life of the related asset. Stock-based Compensation —We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost is recognized over the vesting period during which an employee is required to provide service in exchange for the award. Adoption of New Accounting Standards Goodwill In the second quarter of 2018, we early adopted the FASB’s guidance simplifying the test for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying value of that goodwill. Under that new guidance, which is applied prospectively, if the carrying value of a reporting unit is greater than its fair value, a goodwill impairment charge will be recorded for the difference up to the carrying value of the goodwill. The loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In the second quarter of 2018, we recorded an impairment charge of $42.9 million on the Consolidated Statements of Operations and an impairment balance of $42.9 million against Goodwill on the Consolidated Statement of Financial Position related to our Canadian reporting unit. (See Note 5. Goodwill and Other Intangible Assets to the Consolidated Financial Statements.) Revenue from Contracts with Customers In the first quarter of 2018, we adopted the FASB’s principles-based guidance addressing revenue recognition issues, applying the modified retrospective method of adoption. The guidance is being applied to all contracts with customers regardless of industry-specific or transaction-specific fact patterns. The guidance requires that the amount of revenue a company should recognize reflect the consideration it expects to be entitled to in exchange for goods and services. The impact of the adoption of the new revenue recognition guidance is primarily applicable to our multi-year transit advertising contracts with municipalities in the U.S. and Canada, and marketing and multimedia rights agreements with colleges, universities and other educational institutions. Our billboard lease revenues are recognized under the lease accounting standard. The adoption of this guidance did not impact revenues from our multi-year transit advertising contracts, but resulted in the recognition of additional revenues of $7.0 million , additional operating expenses of $4.8 million and additional selling, general and administrative expenses of $2.2 million in our Sports Marketing operating segment in 2018 , related to revenues that would have been recognized on a net basis under the old standard. Adoption of this guidance did not have a material effect on our consolidated financial statements. (See Note 11. Revenues to the Consolidated Financial Statements.) Recent Pronouncements Leases In February 2016 (updated in July 2018 and December 2018), the FASB issued guidance addressing the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. Lessors will account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. The update in July 2018 provides an additional (optional) transition method to adopt the new lease standard, allowing entities to apply the new lease standard at the adoption date rather than adjusting each period presented at the date of adoption. The update also provides lessors a practical expedient to allow them to not separate non-lease components from the associated lease component and instead to account for those components as a single component if certain criteria are met. We plan to utilize the updated transition method beginning January 1, 2019. The updated practical expedient for lessors will not have a material effect on our consolidated financial statements. As of December 31, 2018 , we had approximately 20,800 lease agreements in the U.S. and approximately 2,800 lease agreements in Canada, the majority of which will be classified as operating leases under the new guidance. We are currently finalizing our implementation of a new lease software system which will enable us to comply with the on-going requirements of this standard, as well as finalizing the impact of adoption on January 1, 2019. This standard will have a significant impact on our consolidated financial statements, as we expect to recognize right-of-use asset and lease liability in excess of $1.0 billion

Goodwill and other intangible assets	Goodwill and Other Intangible Assets Goodwill For the years ended December 31, 2018 and 2017 , the changes in the book value of goodwill by segment were as follows: (in millions) U.S. Media Other Total As of December 31, 2016 $ 2,054.0 $ 35.4 $ 2,089.4 Currency translation adjustments — 4.3 4.3 Additions (a) — 34.3 34.3 As of December 31, 2017 2,054.0 74.0 $ 2,128.0 Currency translation adjustments — (5.4 ) (5.4 ) Impairment — (42.9 ) (42.9 ) As of December 31, 2018 $ 2,054.0 $ 25.7 $ 2,079.7 (a) Non-deductible addition associated with the Transaction (as defined below, see Note 10. Equity and Note 13. Acquisitions and Dispositions to the Consolidated Financial Statements). In the fourth quarter of 2018, we performed a qualitative and/or a quantitative assessment of our reporting units for possible goodwill impairment. Upon assessment, no goodwill impairment was identified. In the second quarter of 2018, our Canadian reporting unit did not meet revenue expectations and pacing reflected a decline as compared to the 2018 forecast due to the underperformance of our static poster assets and digital displays. As a result, we determined that there was a decline in the outlook for our Canadian reporting unit. This determination constituted a triggering event, requiring an interim goodwill impairment analysis of our Canadian reporting unit. As a result of the impairment analysis performed during the second quarter of 2018, we determined that the carrying value of our Canadian reporting unit exceeded its fair value and we recorded an impairment charge of $42.9 million on the Consolidated Statements of Operations. As of December 31, 2018 , goodwill related to our Canadian reporting unit, net of accumulated impairment of $42.9 million , was $19.8 million . As of December 31, 2017, goodwill associated with our Canadian reporting unit was $68.1 million . Other Intangible Assets Our identifiable intangible assets primarily consist of acquired permits and leasehold agreements and franchise agreements which grant us the right to operate out-of-home structures in specified locations and the right to provide advertising space on railroad and municipal transit properties. Identifiable intangible assets are amortized on a straight-line basis over their estimated useful life, which is the respective life of the agreement that in some cases includes historical experience of renewals. Our identifiable intangible assets consist of the following: (in millions) Gross Accumulated Amortization Net As of December 31, 2018: Permits and leasehold agreements (a) $ 1,107.4 $ (697.6 ) $ 409.8 Franchise agreements 470.7 (357.1 ) 113.6 Other intangible assets (a) 46.9 (33.1 ) 13.8 Total intangible assets $ 1,625.0 $ (1,087.8 ) $ 537.2 As of December 31, 2017: Permits and leasehold agreements $ 1,111.3 $ (661.6 ) $ 449.7 Franchise agreements 455.4 (346.2 ) 109.2 Other intangible assets 47.1 (25.1 ) 22.0 Total intangible assets $ 1,613.8 $ (1,032.9 ) $ 580.9 (a) Includes additions associated with the Transaction (as defined below, see Note 10. Equity and Note 13. Acquisitions and Dispositions to the Consolidated Financial Statements). All of our intangible assets, except goodwill, are subject to amortization. Amortization expense was $99.1 million in 2018 , $100.1 million in 2017 and $115.3 million in 2016 , which includes the amortization of direct lease acquisition costs of $43.2 million in 2018 , $40.0 million in 2017 and $38.2 million in 2016 . Direct lease acquisition costs are amortized on a straight-line basis over the related customer lease term, which generally ranges from four weeks to one year. We expect our aggregate annual amortization expense for intangible assets, before considering the impact of future direct lease acquisition costs, for each of the years 2019 through 2023 , to be as follows: (in millions) 2019 2020 2021 2022 2023 Amortization expense $ 55.5 $ 50.9 $ 49.3 $ 44.5 $ 43.7

As of December 31, 2018 , a discount of $1.9 million on the Term Loan remains unamortized. The discount is being amortized through Interest expense, net, on the Consolidated Statement of Operations. Revolving Credit Facility We also have a $430.0 million revolving credit facility, which matures in 2022 (the “Revolving Credit Facility,” together with the Term Loan, the “Senior Credit Facilities”). As of December 31, 2018 , there were no outstanding borrowings under the Revolving Credit Facility. The commitment fee based on the amount of unused commitments under the Revolving Credit Facility was $1.4 million in 2018 , $1.5 million in 2017 and $1.8 million in 2016 . As of December 31, 2018 , we had issued letters of credit totaling approximately $66.0 million against the letter of credit facility sublimit under the Revolving Credit Facility. Standalone Letter of Credit Facilities As of December 31, 2018 , we had issued letters of credit totaling approximately $142.9 million under our aggregate $150.0 million standalone letter of credit facilities. The total fees under the letter of credit facilities in 2018 , 2017 and 2016 , were immaterial. Accounts Receivable Securitization Facilities On September 6, 2018, the Company, certain subsidiaries of the Company and MUFG Bank, Ltd. (f/k/a The Bank of Tokyo-Mitsubishi UFJ, Ltd.) (“MUFG”) entered into amendments to the agreements governing the Company’s $100.0 million three-year revolving accounts receivable securitization facility (the “AR Facility”), along with other agreements with MUFG, pursuant to which the Company (i) extended the term of the AR Facility for one year so that it will now terminate on June 30, 2021, unless further extended, and (ii) entered into a 364-day $75.0 million structured repurchase facility (the “Repurchase Facility” and together with the AR Facility, the “AR Securitization Facilities”). In connection with the AR Securitization Facilities, Outfront Media LLC, a wholly-owned subsidiary of the Company (the “Originator”), will sell and/or contribute its existing and future accounts receivable and certain related assets to Outfront Media Receivables LLC, a special purpose vehicle and wholly-owned subsidiary of the Company (the “SPV”). The SPV will transfer an undivided interest in the accounts receivable assets to certain purchasers from time to time (the “Purchasers”). The SPV is a separate legal entity with its own separate creditors who will be entitled to access the SPV’s assets before the assets become available to the Company. Accordingly, the SPV’s assets are not available to pay creditors of the Company or any of its subsidiaries, although collections from the receivables in excess of amounts required to repay the Purchasers and other creditors of the SPV may be remitted to the Company. In connection with the Repurchase Facility, the Originator may borrow up to $75.0 million , collateralized by a subordinated note (the “Subordinated Note”) issued by the SPV in favor of the Originator and representing a portion of the outstanding balance of the accounts receivable assets sold by the Originator to the SPV under the AR Facility. The Subordinated Note will be transferred to MUFG, as repurchase buyer, on an uncommitted basis, and subject to repurchase by the Originator on termination of the Repurchase Facility. The Originator has granted MUFG a security interest in the Subordinated Note to secure its obligations under the agreements governing the Repurchase Facility, and the Company has agreed to guarantee the Originator’s obligations under the agreements governing the Repurchase Facility. As of December 31, 2018 , there were $85.0 million of outstanding borrowings under the AR Facility at a borrowing rate of approximately 3.5% , and $75.0 million of outstanding borrowings under the Repurchase Facility, at a borrowing of approximately 3.7% . As of December 31, 2018 , borrowing capacity remaining under the AR Facility was approximately $15.0 million , based on approximately $216.0 million of accounts receivable used as collateral for the AR Securitization Facilities, and there was no borrowing capacity remaining under the Repurchase Facility, in accordance with the agreements governing the AR Securitization Facilities. The commitment fee based on the amount of unused commitments under the AR Facility was immaterial in 2018 and 2017 . As of February 26, 2019 , there were $65.0 million of outstanding borrowings under the AR Facility at a borrowing rate of approximately 3.6% and $75.0 million of outstanding borrowings under the Repurchase Facility, at a borrowing rate of approximately 3.7% . Senior Unsecured Notes As of December 31, 2018 , a discount of $0.3 million on $150.0 million aggregate principal amount of the 5.250% Senior Unsecured Notes due 2022 , remains unamortized. The discount is being amortized through Interest expense, net, on the Consolidated Statement of Operations. As of December 31, 2018 , a premium of $2.2 million on $100.0 million aggregate principal amount of the 5.625% Senior Unsecured Notes, due 2024 , remains unamortized. The premium is being amortized through Interest expense, net , on the Consolidated Statement of Operations. Debt Covenants Our credit agreement, dated as of January 31, 2014 (as amended, supplemented or otherwise modified, the “Credit Agreement”), governing the Senior Credit Facilities, the agreements governing the AR Securitization Facilities, and the indentures governing our senior unsecured notes contain customary affirmative and negative covenants, subject to certain exceptions, including but not limited to those that limit the Company’s and our subsidiaries’ abilities to (i) pay dividends on, repurchase or make distributions in respect to the Company’s or its wholly-owned subsidiary, Outfront Media Capital LLC’s (“Finance LLC’s”) capital stock or make other restricted payments other than dividends or distributions necessary for us to maintain our REIT status, subject to certain conditions, and (ii) enter into agreements restricting certain subsidiaries’ ability to pay dividends or make other intercompany or third-party transfers. The terms of the Credit Agreement (and under certain circumstances, the agreements governing the AR Securitization Facilities) require that we maintain a Consolidated Net Secured Leverage Ratio, which is the ratio of (i) our consolidated secured debt (less up to $150.0 million of unrestricted cash) to (ii) our Consolidated EBITDA (as defined in the Credit Agreement) for the trailing four consecutive quarters, of no greater than 4.0 to 1.0. As of December 31, 2018 , our Consolidated Net Secured Leverage Ratio was 1.4 to 1.0 in accordance with the Credit Agreement. The Credit Agreement also requires that, in connection with the incurrence of certain indebtedness, we maintain a Consolidated Total Leverage Ratio, which is the ratio of our consolidated total debt to our Consolidated EBITDA for the trailing four consecutive quarters, of no greater than 6.0 to 1.0. As of December 31, 2018 , our Consolidated Total Leverage Ratio was 4.6 to 1.0 in accordance with the Credit Agreement. As of December 31, 2018 , we are in compliance with our debt covenants. Deferred Financing Costs As of December 31, 2018 , we had deferred $24.1 million in fees and expenses associated with the Term Loan, Revolving Credit Facility, AR Securitization Facilities and our senior unsecured notes. We are amortizing the deferred fees through Interest expense, net, on our Consolidated Statement of Operations over the respective terms of the Term Loan, Revolving Credit Facility, AR Securitization Facilities and our senior unsecured notes. Interest Rate Swap Agreements During the year ended December 31, 2018, we entered into several interest rate cash flow swap agreements to effectively convert a portion of our LIBOR-based variable rate debt to a fixed rate. The fair value of these swap positions was a net liability of approximately $2.4 million as of December 31, 2018, and is included in Other liabilities on our Consolidated Statement of Financial Position. As of December 31, 2018, under the terms of the agreements, we will pay interest based on an aggregate notional amount of $150.0 million , under a weighted-average fixed interest rate of 3.0% , with a receive rate of one-month LIBOR and maturing on December 29, 2021 . The one-month LIBOR rate was approximately 2.5% as of December 31, 2018. Fair Value Under the fair value hierarchy, observable inputs such as unadjusted quoted prices in active markets for identical assets or liabilities are defined as Level 1; observable inputs other than quoted prices included within Level 1 that are either directly or indirectly observable for the asset or liability are defined as Level 2; and unobservable inputs for the asset or liability are defined as Level 3. The aggregate fair value of our debt, which is estimated based on quoted market prices of similar liabilities, was approximately $2.3 billion as of both December 31, 2018 and 2017 . The fair value of our debt as of both December 31, 2018 and 2017 is classified as Level 2. The aggregate fair value loss associated with our interest rate cash flow swap agreements was approximately $2.4 million as of December 31, 2018

Equity [Abstract]
Equity	Equity As of December 31, 2018 , 450,000,000 shares of our common stock, par value $0.01 per share, were authorized; 140,239,977 shares were issued and outstanding; and 50,000,000 shares of our preferred stock, par value $0.01 per share, were authorized with no shares issued and outstanding. On June 13, 2017, certain subsidiaries of OUTFRONT Media Inc. acquired the equity interests of certain subsidiaries of All Vision LLC (“All Vision”), which hold substantially all of All Vision’s outdoor advertising assets in Canada, and effectuated an amalgamation of All Vision’s Canadian business with our Canadian business (the “Transaction”) (see Note 13. Acquisitions and Dispositions to the Consolidated Financial Statement s ). In connection with the Transaction, the Company issued 1,953,407 shares of Class A equity interests of a subsidiary of the Company that controls its Canadian business (“Outfront Canada”). The Class A equity interests are entitled to receive priority cash distributions from Outfront Canada at the same time and in the same per share amount as the dividends paid on shares of the Company’s common stock. The Class A equity interests may be redeemed by the holders in exchange for shares of the Company’s common stock on a one-for-one basis (subject to anti-dilution adjustments) or, at the Company’s option, cash equal to the then fair market value of the shares of the Company’s common stock commencing (i) one year after closing, with respect to 55% of the Class A equity interests, and (ii) 18 months after closing, with respect to the remaining 45% of the Class A equity interests. In connection with the Transaction, the Company has agreed to limitations on its ability to sell or otherwise dispose of the assets acquired from All Vision for a period of five years, unless it pays holders of the Class A equity interests in Outfront Canada an amount intended to approximate their resulting tax liability. During 2018 , we made distributions of $2.7 million to holders of the Class A equity interests, which are recorded in Dividends on our Consolidated Statements of Equity and Consolidated Statements of Cash Flows. As of December 31, 2018 , 207,354 Class A equity interests have been redeemed for shares of the Company’s common stock. In the third quarter of 2018, we issued 7,442 shares of our common stock under the Outfront Media Inc. Amended and Restated Omnibus Stock Incentive Plan, valued at $0.1 million , to a consultant for services rendered. We have a sales agreement in connection with an “at-the-market” equity offering program (the “ATM Program”), under which we may, from time to time, issue and sell shares of our common stock up to an aggregate offering price of $300.0 million . We have no obligation to sell any of our common stock under the sales agreement and may at any time suspend solicitations and offers under the sales agreement. In the fourth quarter of 2018 , 750,000 shares of our common stock were sold under the ATM Program for gross proceeds of $15.5 million with commissions of $0.2 million , for total net proceeds of $15.3 million .

Revenue from Contract with Customer [Abstract]
Revenues	Revenues We do not disclose the value of unsatisfied performance obligations for contracts with an original expected term of one year or less, which primarily represent the transaction price allocated to the remaining display period for unsatisfied transit franchise contracts. Unsatisfied performance obligations with an original expected term of over one year relate to multi-year marketing and multimedia rights agreements with customers of our Sports Marketing operating segment, the value of which is $80.2 million as of December 31, 2018 , are expected to be satisfied over the next 5 years . For all revenue sources, we evaluate whether we should be considered the principal (i.e., report revenues on a gross basis) or an agent (i.e., report revenues on a net basis). Except for an insignificant number of smaller sports marketing contracts, we are considered the principal in our arrangements and report revenues on a gross basis, wherein the amounts billed to customers are recorded as revenues, and amounts paid to municipalities, transit operators, educational institutions and suppliers are recorded as expenses. We are considered the principal because we control the advertising space and multi-media rights before and after the contract term, are primarily responsible to our customers, have discretion in pricing and typically have inventory risk. For space provided to advertisers through the use of an advertising agency whose commission is calculated based on a stated percentage of gross advertising spending, our Revenues are reported net of agency commissions. The following table summarizes revenues by source: Years Ended December 31, (in millions) 2018 2017 2016 Billboard: Static displays $ 858.1 $ 839.7 $ 880.3 Digital displays 216.1 173.7 155.9 Other 38.2 45.6 34.8 Billboard revenues 1,112.4 1,059.0 1,071.0 Transit: Static displays 339.9 339.5 331.7 Digital displays 59.6 45.3 39.8 Other 39.5 35.9 30.0 Total transit revenues 439.0 420.7 401.5 Sports marketing and other 54.8 40.8 41.4 Transit and other revenues 493.8 461.5 442.9 Total revenues $ 1,606.2 $ 1,520.5 $ 1,513.9 Rental income was $1,074.2 million in 2018, $1,013.4 million in 2017 and $1,036.2 million in 2016, and is recorded in Billboard revenues on the Consolidated Statement of Operations.

Contract Costs and Balances Variable sales commission costs directly associated with billboard display revenues are considered direct lease acquisition costs in accordance with the lease accounting standard and are capitalized and amortized on a straight-line basis over the related customer lease term (see Note 5. Goodwill and Other Intangible Assets to the Consolidated Financial Statements). Amortization of direct lease acquisition costs is presented within Amortization expense in the accompanying Consolidated Statements of Operations. Variable sales commission costs which are directly associated with transit display and other revenues are included in Selling, general, and administrative expenses on the Consolidated Statement of Operations, and are expensed as incurred since the amortization period of the asset would have been less than one year. Amounts to be collected from customers for revenues recognized in previous periods are included in Receivables, less allowance , on the Consolidated Statement of Financial Position. Amounts collected from customers for revenues to be recognized in future periods are included in Deferred revenues on the Consolidated Statement of Financial Position. We recognized substantially all of the Deferred revenues

Acquisitions and Dispositions	Acquisitions and Dispositions Acquisitions In connection with the Transaction, the Company paid approximately $94.4 million for the assets, comprised of $50.0 million in cash and $44.4 million , or 1,953,407 shares, of Class A equity interests of Outfront Canada, subject to post-closing adjustments (upward or downward) for the achievement of certain operating income before depreciation and amortization targets relating to the acquired assets in 2018, which is not expected to be material. The issued Class A equity interests of Outfront Canada are redeemable non-controlling interests and are included in Non-controlling interests on our Consolidated Statement of Financial Position based on actual foreign currency exchange rates on the closing date of the Transaction compared to the negotiated foreign currency exchange rate used in the valuation described above. The allocation of the purchase price of approximately $94.4 million is based on management’s estimate of the fair value of the assets acquired and liabilities assumed on the closing date of the Transaction, which was $68.0 million of identified intangible assets, $34.3 million of goodwill, $17.0 million of deferred tax liabilities and $9.1 million of other assets and liabilities (primarily property and equipment). We completed several acquisitions for a total purchase price of approximately $7.0 million in 2018 , $113.8 million in 2017 (including the Transaction) and $67.9 million in 2016 . In the second quarter of 2018, we entered into an agreement to acquire 14 digital and 7 static billboard displays in California for a total estimated purchase price of $35.4 million , subject to post-closing adjustments for the achievement of operating income before depreciation and amortization targets relating to the acquired displays. The transaction is expected to close in 2019, subject to customary closing conditions and the timing of site development. Dispositions On April 1, 2016 , we completed the Disposition and received $82.0 million in cash plus working capital, which was subject to post-closing adjustments. We recorded a loss on real estate assets held for sale of approximately $1.3 million in 2016 on the Consolidated Statement of Operations. Asset Swap On July 1, 2017, in exchange for static billboards in four non-metropolitan market clusters, we acquired digital billboards in the Boston, Massachusetts, DMA and $3.2 million in cash, which resulted in a pre-tax gain of $14.1 million

Stock-Based Compensation	Stock-Based Compensation Under the OUTFRONT Media Inc. Amended and Restated Omnibus Stock Incentive Plan (the “Stock Plan”), we have 8,000,000 shares of our common stock reserved for the issuance of stock-based awards. Under the Stock Plan, the board of directors is authorized to grant awards of options to purchase shares of our common stock, stock appreciation rights, restricted and unrestricted stock, restricted share units (“RSUs”), dividend equivalents, performance awards, including performance-based restricted share units (“PRSUs”), and other equity-related awards and cash payments to all of our employees and non-employee directors and employees of our subsidiaries. In addition, consultants and advisors who perform services for us and our subsidiaries may, under certain conditions, receive grants under the Stock Plan. RSUs and PRSUs accrue dividend equivalents in amounts equal to the regular cash dividends paid on our common stock and will be paid in either cash or stock. Accrued dividend equivalents payable in stock shall convert to shares of our common stock on the date of vesting. Compensation expense for RSUs is determined based upon the market price of the shares underlying the awards on the date of grant and expensed over the vesting period, which is generally a three- to four-year service period. For PRSU awards, the number of shares an employee earns may range from 0% to 120% based on the outcome of a one year performance condition. Compensation expense is recorded based on the probable outcome of the performance condition. On an annual basis, our board of directors will review actual performance and certify the degree to which performance goals applicable to the award have been met. Forfeitures of RSUs are recorded as incurred. On an annual basis, adjustments are made to compensation expense based on actual forfeitures and the forfeiture rates are revised as necessary.

Retirement Benefits [Abstract]
Retirement Benefits	Retirement Benefits We sponsor two defined benefit pension plans covering specific groups of employees in Canada and the U.S. The benefits for the pension plan in Canada are based primarily on an employee’s years of service and an average of the employee’s highest five years of earnings. Participating employees in the pension plan in Canada are vested after two years of service or immediately, depending on the province of their employment. We fund the pension plan in Canada in accordance with the rules and regulations of the Pension Benefits Act of the Province of Ontario, Canada. Canada pension plan assets consist principally of equity securities, corporate and government related securities, and insurance contracts. The pension plan in the U.S. covers a small number of hourly employees. The investments of the pension plan in the U.S. consist entirely of the plan’s interest in a trust, which invests the assets of this plan. The pension plan in the U.S. is funded in accordance with requirements of the Employee Retirement Income Security Act of 1974, as amended. We use a December 31 measurement date for all pension plans. The following table sets forth the change in benefit obligation for our pension plans. As of December 31, (in millions) 2018 2017 2016 Benefit obligation, beginning of year $ 57.8 $ 48.3 $ 44.9 Service cost 1.8 1.6 1.6 Interest cost 2.0 2.0 1.9 Actuarial (gain) loss (5.6 ) 3.7 0.2 Benefits paid (2.0 ) (1.4 ) (1.5 ) Cumulative translation adjustments (4.1 ) 3.6 1.2 Benefit obligation, end of year $ 49.9 $ 57.8 $ 48.3 The following table sets forth the change in plan assets for our pension plans.

Estimated net actuarial losses related to the defined benefit pension plans of approximately $0.4 million , will be amortized from accumulated other comprehensive loss into net periodic pension costs in 2019 . As of and for the Year Ended December 31, 2018 2017 Weighted average assumptions used to determine benefit obligations: Discount rate 4.0 % 3.5 % Rate of compensation increase 3.0 3.0 Weighted average assumptions used to determine net periodic cost: Discount rate 3.5 4.0 Expected long-term return on plan assets 5.1 5.1 Rate of compensation increase 3.0 3.0 For each pension plan, the discount rate is determined based on the yield on portfolios of high quality bonds, constructed to provide cash flows necessary to meet the expected future benefit payments, as determined for the projected benefit obligation. The expected return on plan assets assumption was derived using the current and expected asset allocation of the pension plan assets and considering historical as well as expected returns on various classes of plan assets. Plan Assets Our plan assets are included in a trust in Canada and a trust in the U.S. The asset allocations of these trusts are based upon an analysis of the timing and amount of projected benefit payments, projected company contributions, the expected returns and risk of the asset classes and the correlation of those returns. As of December 31, 2018 , we invested approximately 31% in fixed income instruments, 59% in equity instruments, and the remainder in cash, cash equivalents and insurance contracts. The following tables set forth our pension plan assets measured at fair value on a recurring basis as of December 31, 2018 and 2017 . These assets have been categorized according to the three-level fair value hierarchy established by the FASB which prioritizes the inputs used in measuring fair value. Level 1 is based on quoted prices for the asset in active markets. Level 2 is based on inputs that are observable other than quoted market prices in active markets, such as quoted prices for the asset in inactive markets or quoted prices for similar assets. Level 3 is based on unobservable inputs that market participants would use in pricing the asset. As of December 31, 2018 (in millions) Level 1 Level 2 Level 3 Total Cash and cash equivalents (a) $ — $ 1.0 $ — $ 1.0 Fixed income securities: Corporate and government related securities — 14.2 — 14.2 Corporate bonds (b) 0.7 — — 0.7 Equity securities (c) : U.S. equity 0.6 — — 0.6 International equity 0.3 27.1 — 27.4 Insurance contracts — — 3.6 3.6 Total assets $ 1.6 $ 42.3 $ 3.6 $ 47.5 As of December 31, 2017 (in millions) Level 1 Level 2 Level 3 Total Cash and cash equivalents (a) $ — $ 1.0 $ — $ 1.0 Fixed income securities: Corporate and government related securities — 15.3 — 15.3 Corporate bonds (b) 0.8 — — 0.8 Equity securities (c) : U.S. equity 1.0 — — 1.0 International equity 0.4 29.4 — 29.8 Insurance contracts — — 4.4 4.4 Total assets $ 2.2 $ 45.7 $ 4.4 $ 52.3 (a) Assets categorized as Level 2 reflect investments in money market funds. (b) Securities of diverse industries, substantially all investment grade. (c) Assets categorized as Level 2 reflect investments in common collective funds. Significant changes in Level 3 plan assets are as follows: Year Ended December 31, (in millions) 2018 2017 Insurance contracts: Beginning of year $ 4.4 $ 4.7 Payments (0.5 ) (0.5 ) Actuarial loss (0.1 ) (0.3 ) Interest income 0.1 0.2 Cumulative translation adjustments (0.3 ) 0.3 End of year $ 3.6 $ 4.4 Our insurance contracts classified as Level 3 are valued based on a discount rate determined by reference to the market interest rates prevailing on high quality debt instruments with cash flows that match the timing and amount of expected benefit payments under the pension plan in Canada, as well as a mortality assumption based upon the current mortality table, CPM2014 generational projected using mortality improvement scale CPM-B. As a result, the fair value of the insurance contract is equal to the defined benefit obligation in respect of the members covered under the insurance contract. Money market investments are carried at amortized cost which approximates fair value due to the short-term maturity of these investments. Investments in equity securities are reported at fair value based on quoted market prices on national security exchanges. The fair value of investments in common collective funds are determined using the Net Asset Value (“NAV”) provided by the administrator of the fund. The NAV is determined by each fund’s trustee based upon the fair value of the underlying assets owned by the fund, less liabilities, divided by the number of outstanding units. The fair value of government related securities and corporate bonds is determined based on quoted market prices on national security exchanges, when available, or using valuation models which incorporate certain other observable inputs including recent trading activity for comparable securities and broker-quoted prices. Future Benefit Payments (in millions) 2019 2020 2021 2022 2023 2024-2028 Estimated future benefit payments for pension plans 1.7 1.7 1.9 2.0 2.1 12.8 We expect to contribute $1.0 million to our pension plans in 2019 . Multi-Employer Pension and Postretirement Benefit Plans We contribute to multi-employer plans that provide pension and other postretirement benefits to certain employees under collective bargaining agreements. Contributions to these plans were $3.8 million in 2018 , $3.3 million in 2017 and $2.9 million in 2016 . Based on our contributions to each individual multi-employer plan relative to the total contributions of all participating employers in such plan, no multi-employer plan was deemed to be individually significant to us. Defined Contribution Plans Employer contributions for defined contribution plans sponsored by us were $5.5 million in 2018 , $4.8 million in 2017 and $4.5 million in 2016

Income Taxes	Income Taxes We are organized in conformity with the requirements for qualification and taxation as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) and, accordingly, we have not provided for U.S. federal income tax on our REIT taxable income that we distribute to our stockholders. We have elected to treat our subsidiaries that participate in certain non-REIT qualifying activities, and our foreign subsidiaries, as taxable REIT subsidiaries (“TRSs”). As such, we have provided for their federal, state and foreign income taxes. On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act amends the Code to reduce tax rates and modify policies, credits and deductions. The Tax Act’s most significant change was the reduction of the federal tax rate from a maximum of 35% to a flat rate of 21% . Cash paid for income taxes was $8.4 million in 2018 and $6.8 million in 2017 and $1.2 million in 2016 .

No provision was recorded for taxes that could result from the remittance of such undistributed earnings since we intend to declare dividends to our shareholders in an amount sufficient to offset such distributions and intend to reinvest the remainder outside of the U.S. indefinitely.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Off-Balance Sheet Arrangements Our off-balance sheet commitments primarily consist of operating lease arrangements and guaranteed minimum annual payments. These arrangements result from our normal course of business and represent obligations that are payable over several years. Contractual Obligations We have long-term operating leases for office space, billboard sites and equipment, which expire at various dates. Certain leases contain varying renewal, cancellation and escalation clauses. We have agreements with municipalities and transit operators which entitle us to operate advertising displays within their transit systems, including on the interior and exterior of rail and subway cars and buses, as well as on benches, transit shelters, street kiosks, and transit platforms. Under most of these franchise agreements, the franchisor is entitled to receive the greater of a percentage of the relevant revenues, net of agency fees, or a specified guaranteed minimum annual payment. We also have marketing and multimedia rights agreements with colleges, universities and other educational institutions, which entitle us to operate on-campus advertising displays, as well as manage marketing opportunities, media rights and experiential entertainment at sports events. Under most of these agreements, the school is entitled to receive the greater of a percentage of the relevant revenue, net of agency commissions, or a specified guaranteed minimum annual payment. Under the MTA agreement, we are obligated to deploy, over a number of years, (i) 8,565 digital advertising screens on subway and train platforms and entrances, (ii) 37,716 smaller-format digital advertising screens on rolling stock (with deployment scheduled to commence in 2019), and (iii) 7,829 MTA communications displays. In addition, we are obligated to pay to the MTA the greater of a percentage of revenues or a guaranteed minimum annual payment. Incremental revenues that exceed an annual base revenue amount will be retained by us for the cost of deploying advertising and communications displays throughout the transit system. As presented in the table below, MTA equipment deployment costs are being recorded as Prepaid MTA equipment deployment costs and Intangible assets on our Consolidated Statement of Financial Position, and as these costs are recouped from incremental revenues that the MTA would otherwise be entitled to receive, Prepaid MTA equipment deployment costs will be reduced. If incremental revenues generated over the term of the agreement are not sufficient to cover all or a portion of the equipment deployment costs, the costs will not be recouped, which could have an adverse effect on our business, financial condition and results of operation. As of December 31, 2018 , 1,229 digital displays had been installed, of which 934 installations occurred in the fourth quarter. For the full year of 2019, we expect our MTA equipment deployment costs to be approximately $175.0 million .

Rent expense is primarily reflected in operating expenses on the Consolidated Statements of Operations and includes rent on cancellable leases and leases with terms under one year, as well as contingent rent, none of which are included in the operating lease commitments in the table above. Letters of Credit We have indemnification obligations with respect to letters of credit and surety bonds primarily used as security against non-performance in the normal course of business. As of December 31, 2018 , the outstanding letters of credit were approximately $208.9 million and outstanding surety bonds were approximately $27.2 million , and were not recorded on the Consolidated Statements of Financial Position.

Accounting Policies [Abstract]
Use of Estimates	The preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amount of revenues and expenses during the reporting period. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation— The consolidated financial statements include the accounts of OUTFRONT Media Inc. and all of its subsidiaries in which a controlling interest is maintained. Controlling interest is determined by majority ownership interest and the absence of substantive third-party participating rights. Investments over which we have a significant influence or ownership of more than 20% but less than or equal to 50% , without a controlling interest, are accounted for under the equity method. Investments of 20%
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash —Cash and cash equivalents consist of cash on hand and short-term (maturities of three months or less at the date of purchase) highly liquid investments. We classify cash balances that are legally restricted pursuant to contractual arrangements as restricted cash.
Receivables	Receivables—Receivables consist primarily of trade receivables from customers, net of advertising agency commissions, and are stated net of an allowance for doubtful accounts. The provision for doubtful accounts is estimated based on historical bad debt experience, the aging of accounts receivable, industry trends and economic indicators, as well as recent payment history for specific customers.
New York Metropolitan Authority Agreement	New York Metropolitan Transportation Authority (the “MTA”) Agreement— Under the MTA Agreement, as title of the various digital displays we are obligated to deploy transfers to the MTA on installation, the cost of deploying these screens throughout the transit system does not represent our property and equipment. The portion of deployment costs expected to be reimbursed from transit franchise fees that would otherwise be payable to the MTA are recorded as Prepaid MTA equipment deployment costs on the Consolidated Statement of Financial Position and charged to operating expenses as advertising revenue is generated. The short-term portion of Prepaid MTA equipment deployment costs represents the costs that we expect to recover from the MTA in the next twelve months. The portion of deployment costs expected to be reimbursed from advertising revenues that would otherwise be retained by us under the contract are recorded as Intangible assets
Property and Equipment	Property and Equipment —Property and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives as follows: Buildings and improvements 20 to 40 years Advertising structures 5 to 20 years Furniture, equipment and other 3 to 10 years For advertising structures associated with a contract, the assets are depreciated over the shorter of the contract term or useful life. Maintenance and repair costs to maintain property and equipment in their original operating condition are charged to expense as incurred. Improvements or additions that extend the useful life of the assets are capitalized. When an asset is retired or otherwise disposed of, the associated cost and accumulated depreciation are removed and the resulting gain or loss is recognized.
Business Combinations and Asset Acquisitions	Business Combinations and Asset Acquisitions—We routinely acquire out-of-home advertising assets, including advertising structures, permits and leasehold agreements. We determine the accounting for these transactions by first evaluating whether the assets acquired and liabilities assumed, if any, constitute a business using the guidelines in the Financial Accounting Standards Board (“FASB”) guidance for business combinations. If the assets acquired and liabilities assumed constitute a business, the purchase price is allocated to the tangible and identifiable intangible net assets acquired based on their estimated fair values with the excess of the purchase price over those estimated fair values recorded as goodwill. If the acquired assets do not constitute a business, we allocate the purchase price to the individual tangible and intangible assets acquired based on their relative fair values.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets— Long-lived assets are assessed for impairment whenever there is an indication that the carrying amount of the asset may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted cash flows generated by those assets to the respective asset’s carrying value. The amount of impairment loss, if any, will be measured by the difference between the net carrying value and the estimated fair value of the asset and recognized as a non-cash charge. Long-lived assets held for sale are required to be measured at the lower of their carrying value (including unrecognized foreign currency translation adjustment losses) or fair value less cost to sell.
Goodwill and Intangible Assets	Goodwill and Intangible Assets— Goodwill is allocated to various reporting units. Goodwill is not amortized but is tested qualitatively and/or quantitatively at the reporting-unit level annually for impairment on October 31 of each year and between annual tests if events occur or circumstances change that would more likely than not reduce the fair value below its carrying amount. A qualitative test assesses macroeconomic conditions, industry and market conditions, cost factors, overall financial performance and other relevant entity specific events, as well as events affecting a reporting unit. If after the qualitative assessment, we determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we perform a quantitative assessment. We may also choose to only perform a quantitative assessment. We compute the estimated fair value of each reporting unit for which we perform a quantitative assessment by adding the present value of the estimated annual cash flows over a discrete projection period to the residual value of the business at the end of the projection period. This technique requires us to use significant estimates and assumptions such as growth rates, operating margins, capital expenditures and discount rates. The estimated growth rates, operating margins and capital expenditures for the projection period are based on our internal forecasts of future performance as well as historical trends. The residual value is estimated based on a perpetual nominal growth rate, which is based on projected long-range inflation and long-term industry projections. The discount rates are determined based on the weighted average cost of capital of comparable entities. There can be no assurance that these estimates and assumptions will prove to be an accurate prediction of the future, and a downward revision of these estimates and/or assumptions would decrease the fair values of our reporting units, which could result in additional impairment charges in the future. If the carrying value of a reporting unit is greater than its fair value, a goodwill impairment charge will be recorded as a non-cash charge for the difference up to the carrying value of the goodwill. The loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Intangible assets, which primarily consist of acquired permits and leasehold agreements and franchise agreements, are amortized by the straight-line method over their estimated useful lives, which range from five to 40 years
Hedging Activities	Hedging Activities—As of December 31, 2018, we utilized interest rate cash flow swap agreements to effectively convert a portion of our LIBOR-based variable rate debt to a fixed rate. These interest rate swaps have been designated and qualify as cash flow hedges and, as a result, changes in the fair value of these swaps are recorded in Other comprehensive income (loss) before taxes on the Consolidated Statements of Comprehensive Income.
Revenue Recognition	Revenue Recognition —We derive Revenues from the following sources: (i) billboard displays, (ii) transit displays, and (iii) other. Billboard display revenues are derived from providing advertising space to customers on our physical billboards or other outdoor structures. We generally (i) own the physical structures on which we display advertising copy for our customers, (ii) hold the legal permits to display advertising thereon, and (iii) lease the underlying sites. Billboard display revenues are recognized under the lease accounting standard as rental income on a straight-line basis over the customer lease term. Transit display revenues are derived from agreements with municipalities and transit operators, which entitle us to operate advertising displays within their transit systems, including on the interior and exterior of rail and subway cars and buses, as well as on benches, transit shelters, street kiosks and transit platforms. Transit display contracts typically require the installation and delivery of multiple advertising displays, for which locations are not specifically identified. Installation services are highly interdependent with the provision of advertising space, and therefore the installation and display of advertising is recognized as a single performance obligation. Transit display revenues are recognized based on the level of units displayed in proportion to the total units to be displayed over the contract period. Other revenues are derived primarily from (i) providing print production services for advertisements to be displayed on our billboards or other outdoor sites, or on displays that we operate within transit systems, and (ii) revenues from marketing and multimedia rights agreements with colleges, universities and other educational institutions, which entitle us to operate on-campus advertising displays, as well as manage marketing opportunities, media rights and experiential entertainment at sports events. Print production services are not interrelated with the provision of advertising space and are considered a distinct performance obligation. Production revenue is recognized over the production period, which is typically very short in duration. Revenues from our Sports Marketing operating segment are principally derived from advertising and marketing arrangements and are recognized over the contract period. Our billboard display and transit display contracts with customers range from four weeks to one year and billing commences at the beginning of the contract term, with payment generally due within 30 days of billing. For the majority of our contracts, transaction prices are explicitly stated. Any contracts with transaction prices that contain multiple performance obligations, are allocated primarily based on a relative standalone selling price basis. Deferred revenues primarily consist of revenues paid in advance of being earned.
Concentration of Credit Risk	Concentration of Credit Risk—In the opinion of management, credit risk is limited due to the large number of customers and advertising agencies utilized. We perform credit evaluations on our customers and agencies and believe that the allowances for doubtful accounts are adequate.
Billboard Property Lease and Transit Franchise Expenses	Billboard Property Lease and Transit Franchise Expenses —Our billboards are primarily located on leased real property. Lease agreements are negotiated for varying terms ranging from one month to multiple years, most of which provide renewal options. Lease costs consist of a fixed monthly amount and certain lease agreements also include contingent rent based on the revenues we generate from the leased site. Property leases are generally paid in advance for periods ranging from one to twelve months . The fixed component of lease costs is expensed evenly over the non-cancellable contract term, and contingent rent is expensed as incurred when the related revenues are recognized.
Direct Lease Acquisition Costs	Direct Lease Acquisition Costs— Variable commissions directly associated with billboard revenues are amortized on a straight-line basis over the related customer lease term, which generally ranges from four weeks to one year. Amortization of direct lease acquisition costs is presented within Amortization
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions— The assets and liabilities of foreign subsidiaries are translated at exchange rates in effect at the balance sheet date, while results of operations are translated at average exchange rates for the respective periods. Any gain or loss on translation is included within other comprehensive income (loss) and Accumulated other comprehensive loss on our Consolidated Statement of Financial Position. Foreign currency transaction gains and losses are included in Other income (expense), net,
Income Taxes	Income Taxes— As of July 17, 2014, we began operating as a REIT. Accordingly, we generally will not be subject to U.S. federal income tax on our REIT taxable income that we distribute to our stockholders. We have elected to treat our subsidiaries that participate in certain non-REIT qualifying activities, and certain of our foreign subsidiaries, as taxable REIT subsidiaries (“TRSs”). As such, the taxable income of our TRSs will be subject to federal, state and foreign income taxation at regular corporate rates. Income taxes are accounted for under the asset and liability method of accounting. Deferred income tax assets and liabilities are recognized for the estimated future tax effects of temporary differences between the financial statement carrying amounts and their respective tax basis. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax assets will not be realized.
Asset Retirement Obligation	Asset Retirement Obligation—An asset retirement obligation is established for the estimated future obligation, upon termination or non-renewal of a lease, associated with removing structures from the leased property and, when required by the contract, the cost to return the leased property to its original condition. These obligations are recorded at their present value in the period in which the liability is incurred and are capitalized as part of the related assets’ carrying value. Accretion of the liability is recognized in selling, general and administrative expenses and the capitalized cost is depreciated over the expected useful life of the related asset.
Stock-based Compensation	Stock-based Compensation—We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost is recognized over the vesting period during which an employee is required to provide service in exchange for the award.
Adoption of New Accounting Standards	Adoption of New Accounting Standards Goodwill In the second quarter of 2018, we early adopted the FASB’s guidance simplifying the test for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying value of that goodwill. Under that new guidance, which is applied prospectively, if the carrying value of a reporting unit is greater than its fair value, a goodwill impairment charge will be recorded for the difference up to the carrying value of the goodwill. The loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In the second quarter of 2018, we recorded an impairment charge of $42.9 million on the Consolidated Statements of Operations and an impairment balance of $42.9 million against Goodwill on the Consolidated Statement of Financial Position related to our Canadian reporting unit. (See Note 5. Goodwill and Other Intangible Assets to the Consolidated Financial Statements.) Revenue from Contracts with Customers In the first quarter of 2018, we adopted the FASB’s principles-based guidance addressing revenue recognition issues, applying the modified retrospective method of adoption. The guidance is being applied to all contracts with customers regardless of industry-specific or transaction-specific fact patterns. The guidance requires that the amount of revenue a company should recognize reflect the consideration it expects to be entitled to in exchange for goods and services. The impact of the adoption of the new revenue recognition guidance is primarily applicable to our multi-year transit advertising contracts with municipalities in the U.S. and Canada, and marketing and multimedia rights agreements with colleges, universities and other educational institutions. Our billboard lease revenues are recognized under the lease accounting standard. The adoption of this guidance did not impact revenues from our multi-year transit advertising contracts, but resulted in the recognition of additional revenues of $7.0 million , additional operating expenses of $4.8 million and additional selling, general and administrative expenses of $2.2 million in our Sports Marketing operating segment in 2018 , related to revenues that would have been recognized on a net basis under the old standard. Adoption of this guidance did not have a material effect on our consolidated financial statements. (See Note 11. Revenues to the Consolidated Financial Statements.)
Recent Pronouncements	Recent Pronouncements Leases In February 2016 (updated in July 2018 and December 2018), the FASB issued guidance addressing the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. Lessors will account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. The update in July 2018 provides an additional (optional) transition method to adopt the new lease standard, allowing entities to apply the new lease standard at the adoption date rather than adjusting each period presented at the date of adoption. The update also provides lessors a practical expedient to allow them to not separate non-lease components from the associated lease component and instead to account for those components as a single component if certain criteria are met. We plan to utilize the updated transition method beginning January 1, 2019. The updated practical expedient for lessors will not have a material effect on our consolidated financial statements. As of December 31, 2018 , we had approximately 20,800 lease agreements in the U.S. and approximately 2,800 lease agreements in Canada, the majority of which will be classified as operating leases under the new guidance. We are currently finalizing our implementation of a new lease software system which will enable us to comply with the on-going requirements of this standard, as well as finalizing the impact of adoption on January 1, 2019. This standard will have a significant impact on our consolidated financial statements, as we expect to recognize right-of-use asset and lease liability in excess of $1.0 billion
