Significant Accounting Policies	(1) Significant Accounting Policies (a) Nature of Business Lamar Advertising Company (the Company) is engaged in the outdoor advertising business, operating approximately 149,900 billboard advertising displays in 45 states, Canada and Puerto Rico. The Company’s operating strategy is to be the leading provider of outdoor advertising services in the markets it serves. In addition, the Company operates a logo sign business in 22 states throughout the United States and the province of Ontario, Canada and operates approximately 53,300 transit advertising displays in 21 states and Canada. Logo signs are erected pursuant to state-awarded service contracts on public rights-of-way near highway exits and deliver brand name information on available gas, food, lodging and camping services. Included in the Company’s logo sign business are tourism signing contracts. The Company provides transit advertising in airport terminals, on bus shelters, benches and buses in the markets it serves. The Company operates as a Real Estate Investment Trust (“REIT”) for U.S. federal income tax purposes and generally will not be subject to federal income taxes on its income and gains that the Company distributes to its stockholders, including the income derived from advertising rental revenue. However, even as a REIT, the Company will remain obligated to pay income taxes on earnings from the assets of its taxable REIT subsidiaries (“TRSs”). In addition, the Company’s foreign assets and operations continue to be subject to taxation in the foreign jurisdictions where those assets are held or those operations are conducted. (b) Principles of Consolidation The accompanying consolidated financial statements include Lamar Advertising Company, its wholly owned subsidiary, Lamar Media Corp. (Lamar Media), and its majority-owned subsidiaries. All inter-company transactions and balances have been eliminated in consolidation. An operating segment is a component of an enterprise: • that engages in business activities from which it may earn revenues and incur expenses; • whose operating results are regularly reviewed by the enterprise’s chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance; and • for which discrete financial information is available. We define the term ‘chief operating decision maker’ to be our executive management group, which consist of our Chief Executive Officer, President and Chief Financial Officer. Currently, all operations are reviewed on a consolidated basis for budget and business plan performance by our executive management group. Additionally, operational performance at the end of each reporting period is viewed in the aggregate by our management group. Any decisions related to changes in invested capital, personnel, operational improvement or training, or to allocate other company resources are made based on the combined results. We operate in a single operating and reporting segment, advertising. We rent advertising space on billboards, buses, shelters, benches, logo plates and in airport terminals. (c) Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. (d) Goodwill and Intangible Assets Goodwill is subject to an annual impairment test. The Company designated December 31 as the date of its annual goodwill impairment test. Impairment testing involves various estimates and assumptions, which could vary, and an analysis of relevant market data and market capitalization. If industry and economic conditions deteriorate, the Company may be required to assess goodwill impairment before the next annual test, which could result in impairment charges. The Company is required to identify its reporting units and determine the carrying value of each reporting unit. The Company has identified two reporting units, Billboard operations and Logo operations, by assigning the assets and liabilities, including the existing goodwill and intangible assets, to those reporting units. The Company is required to determine the fair value of each reporting unit and compare it to the carrying amount of the reporting unit. To the extent the carrying amount of a reporting unit exceeds the fair value of the reporting unit, the Company would be required to book an impairment loss. The fair value of each reporting unit exceeded its carrying amount at its annual impairment test date on December 31, 2017 and 2016; therefore, the Company was not required to recognize an impairment loss. Intangible assets, consisting primarily of site locations, customer lists and contracts, and non-competition agreements are amortized using the straight-line method over the assets estimated useful lives, generally from 2 to 15 years. (e) Impairment of Long-Lived Assets Long-lived assets, such as property, plant and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset or asset group before interest expense. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset or asset group. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the balance sheet. (f) Acquisitions The Company accounts for transactions that meet the definition of a business and group asset purchases as acquisitions. For transactions that meet the definition of a business combination, the Company allocates the purchase price, including any contingent consideration, to the assets acquired and the liabilities assumed at their estimated fair values as of the date of the acquisition with any excess of the purchase price paid over the estimated fair value of net assets acquired recorded as goodwill. For transactions that meet the definition of asset group purchases, the Company allocates the purchase price to the assets acquired and the liabilities assumed at their estimated fair values as of the date of the acquisition. If a transaction is determined to be a group of assets, any direct acquisition costs are capitalized. Transaction costs for transactions determined to be a business combination are expensed as incurred. The fair value of the assets acquired and liabilities assumed is typically determined by using either estimates of replacement costs or discounted cash flow valuation methods. When determining the fair value of tangible assets acquired, the Company must estimate the cost to replace the asset with a new asset, adjusted for an estimated reduction in fair value due to age of the asset, and the economic useful life. When determining the fair value of intangible assets acquired, the Company must estimate the applicable discount rate and the timing and amount of future cash flows. The determination of the final purchase price and the acquisition-date fair value of identifiable assets acquired and liabilities assumed may extend over more than one period and result in adjustments to the preliminary estimate recognized in the prior period financial statements. Effective October 1, 2016, the Company changed its accounting for business combinations, as further discussed in note 20 to the consolidated financial statements. (g) Deferred Income Deferred income consists principally of advertising revenue invoiced in advance. Deferred advertising revenue is recognized in income over the term of the contract. (h) Revenue Recognition The Company recognizes outdoor advertising revenue on an accrual basis ratably over the term of the contracts. Production revenue and the related expense for the advertising copy are recognized upon completion of the sale. The Company engages in barter transactions where the Company trades advertising space for goods and services. The Company recognizes revenues and expenses from barter transactions at fair value, which is determined based on the Company’s own historical practice of receiving cash for similar advertising space from buyers unrelated to the party in the barter transaction. The amount of revenue and expense recognized for advertising barter transactions is as follows: 2017 2016 2015 Net revenues $ 8,469 $ 8,051 $ 7,956 Direct advertising expenses $ 3,603 $ 3,559 $ 3,137 General and administrative expenses $ 4,332 $ 4,067 $ 4,407 (i) Income Taxes As a REIT, the Company is generally not subject to federal income taxes on income and gains distributed to the Company’s stockholders. However, the Company remains obligated to pay income taxes on earnings from domestic TRSs. In addition, the Company’s foreign assets and operations continue to be subject to taxation in the foreign jurisdictions where those assets are held or where those operations are conducted, including those designated as Qualified REIT Subsidiaries, or QRSs, for federal income tax purposes. Accordingly, the consolidated financial statements reflect provisions for federal, state, local and foreign income taxes. The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, as well as operating loss and tax credit carryforwards. The Company measures deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carry forwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities as a result of a change in tax rates is recognized in income in the period that includes the enactment date. (j) Dividends/Distributions As a REIT, the Company must annually distribute to its stockholders an amount equal to at least 90% of its REIT taxable income (determined before the deduction for distributed earnings and excluding any net capital gain). During the year ended December 31, 2017, the Company declared distributions of $325,462 or $3.32 per share, including paid distributions of $243,928 or $2.49 per share. During the years ended 2016 and 2015, the Company declared and paid distributions of its REIT taxable income of an aggregate of $293,600 or $3.02 per share and $265,145 or $2.75 per share, respectively. The amount, timing and frequency of future distributions will be at the sole discretion of the Board of Directors and will be declared based upon various factors, a number of which may be beyond the Company’s control, including the financial condition and operating cash flows, the amount required to maintain REIT status and reduce any income and excise taxes that the Company otherwise would be required to pay, limitations on distributions in its existing and future debt instruments, the Company’s ability to utilize net operating losses (“NOLs”) to offset, in whole or in part, the Company’s distribution requirements, limitations on its ability to fund distributions using cash generated through its TRSs and other factors that the Board of Directors may deem relevant. During the years ended December 31, 2017, 2016 and 2015, the Company accrued or paid cash dividend distributions to holders of its Series AA Preferred Stock of $365 or $63.80 per share. (k) Earnings Per Share The calculation of basic earnings per share excludes any dilutive effect of stock options, while diluted earnings per share includes the dilutive effect of stock options. For the years ended December 31, 2017, 2016 and 2015 there were no dilutive shares excluded from the calculation. (l) Stock Based Compensation Compensation expense for share-based awards is recognized based on the grant date fair value of those awards. Stock-based compensation expense includes an estimate for pre-vesting forfeitures and is recognized over the requisite service periods of the awards on a straight-line basis, which is generally commensurate with the vesting term. Non-cash compensation expense recognized during the years ended December 31, 2017, 2016, and 2015 were $9,599, $28,560 and $25,890, respectively. The $9,599 expensed during the year ended December 31, 2017 consists of (i) $3,636 related to stock options, (ii) $5,589 related to stock grants made under the Company’s performance-based stock incentive program in 2017 and (iii) $374 related to stock awards to directors. See Note 14 for information on the assumptions used to calculate the fair value of stock-based compensation. (m) Cash and Cash Equivalents The Company considers all highly-liquid investments with original maturities of three months or less to be cash equivalents. (n) Foreign Currency Translation Local currencies generally are considered the functional currencies outside the United States. Assets and liabilities for operations in local-currency environments are translated at year-end exchange rates. Income and expense items are translated at average rates of exchange prevailing during the year. Foreign currency translation adjustments are recorded as a component of other comprehensive income (loss) in the Consolidated Statements of Income and Comprehensive Income and as a component of accumulated comprehensive income (loss) in the Consolidated Statements of Stockholders’ Equity. (o) Asset Retirement Obligations The Company is required to record the fair value of obligations associated with the retirement of tangible long-lived assets in the period in which it is incurred. The liability is capitalized as part of the related long-lived asset’s carrying amount. Over time, accretion of the liability is recognized as an operating expense and the capitalized cost is depreciated over the expected useful life of the related asset. The Company’s asset retirement obligations relate primarily to the dismantlement, removal, site reclamation and similar activities of its leased properties. (p) Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (q) Comprehensive Income Total comprehensive income is presented in the Consolidated Statements of Income and Comprehensive Income and the components of accumulated comprehensive income (loss) are presented in the Consolidated Statements of Stockholders’ Equity. Comprehensive income (loss) is composed of foreign currency translation effects. (r) Fair Value Measurements The Company determines the fair value of its financial instruments using the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. (s) Subsequent Events The Company has performed an evaluation of subsequent events through the date on which the financial statements are issued.

Senior Credit Facility On May 15, 2017, Lamar Media entered into a Third Restatement Agreement (“Restatement Agreement”) to its Second Amended and Restated Credit Agreement (“existing senior credit facility”) dated as of February 3, 2014 with the Company, certain of Lamar Media’s subsidiaries as guarantors, JPMorgan Chase Bank, N.A. as administrative agent and the lenders party thereto, under which the parties agreed to amend and restate Lamar Media’s existing senior credit facility. Lamar Media’s Third Amended and Restated Credit Agreement dated as of May 15, 2017 (as amended, the “senior credit facility”) consists of (i) a new $450,000 senior secured revolving credit facility which will mature on May 15, 2022, (ii) a new $450,000 Term A loan facility (the “Term A loans”) which will mature on May 15, 2022, and (iii) an incremental facility pursuant to which Lamar Media may incur additional term loan tranches or increase its revolving credit facility subject to pro forma compliance with the secured debt ratio financial maintenance covenant. Under the senior credit facility Lamar Media borrowed all $450,000 in Term A loans on May 15, 2017. The net proceeds, together with borrowing under the revolving portion of senior credit facility and cash on hand, were used to repay all outstanding amounts under the existing senior credit facility, and all revolving commitments under that facility were terminated. The Term A loans began amortizing on September 30, 2017 in quarterly installments on each December 31, March 31, June 30 and September 30 thereafter, as follows: Principal Payment Date Principal Amount March 31, 2018-June 30, 2019 $ 5,625.0 September 30, 2019-June 30, 2020 $ 8,437.5 September 30, 2020-March 31, 2022 $ 16,875.0 Term A Loan Maturity Date $ 253,125.0 For each borrowing of Term A loans or revolving credit loans, Lamar Media can elect whether such loans bear interest at (i) the Adjusted Base Rate plus (a) 0.75%, or (b) 0.50% at any time that the total debt ratio is less than 3.25 to 1 as of the last day of the most recently ended fiscal quarter for which Lamar Media has delivered financial statements, or (ii) the Adjusted LIBO Rate plus (a) 1.75%, or (b) 1.50% at any time that the total debt ratio is less than 3.25 to 1 as of the last day of the most recently ended fiscal quarter for which Lamar Media has delivered financial statements. As of December 31, 2017, there was $198,000 outstanding under the revolving credit facility. Availability under the revolving facility is reduced by the amount of any letters of credit outstanding. Lamar Media had $12,950 letters of credit outstanding as of December 31, 2017 resulting in $239,050 of availability under its revolving facility. Revolving credit loans may be requested under the revolving credit facility at any time prior to its maturity on May 15, 2022. The terms of Lamar Media’s senior credit facility and the indentures relating to Lamar Media’s outstanding notes restrict, among other things, the ability of Lamar Advertising and Lamar Media to: • dispose of assets; • incur or repay debt; • create liens; • make investments; and • pay dividends. The senior credit facility contains provisions that would allow Lamar Media to conduct its affairs in a manner that would allow Lamar Advertising to qualify and remain qualified as a REIT, including by allowing Lamar Media to make distributions to Lamar Advertising required for the Company to qualify and remain qualified for taxation as a REIT, subject to certain restrictions. Lamar Media’s ability to make distributions to Lamar Advertising is also restricted under the terms of these agreements. Under Lamar Media’s senior credit facility the Company must maintain a specified senior debt ratio at all times and in addition, must satisfy a total debt ratio in order to incur debt, make distributions or make certain investments. Lamar Advertising and Lamar Media were in compliance with all of the terms of their indentures and the applicable senior credit agreement provisions during the periods presented.

Income Taxes	(11) Income Taxes Commencing January 1, 2014, the Company began operating as a REIT for U.S. income tax purposes. Since operating as a REIT, the Company filed, and intends to continue to file, as a REIT, and its TRSs filed, and intend to continue to file, as C corporations. The Company also files tax returns in various states and countries. The Company’s state tax returns reflect different combinations of the Company’s subsidiaries and are dependent on the connection each subsidiary has with a particular state. The following information pertains to the Company’s income taxes on a consolidated basis. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “TCJA”) was signed into law, making significant changes to the Internal Revenue Code. As a result of the TCJA, a tax benefit of $3,372 and $466 has been recorded to current tax expense and deferred tax expense, respectively, for the year ended December 31, 2017. Income tax expense (benefit) consists of the following: Current Deferred Total Year ended December 31, 2017: U.S. federal $ 4,174 $ 359 $ 4,533 State and local 2,706 (170 ) 2,536 Foreign 1,546 615 2,161 $ 8,426 $ 804 $ 9,230 Year ended December 31, 2016: U.S. federal $ 9,518 $ (935 ) $ 8,583 State and local 2,681 (6 ) 2,675 Foreign 1,500 598 2,098 $ 13,699 $ (343 ) $ 13,356 Year ended December 31, 2015: U.S. federal $ 7,686 $ (930 ) $ 6,756 State and local 1,746 (246 ) 1,500 Foreign 1,527 12,275 13,802 $ 10,959 $ 11,099 $ 22,058 As of December 31, 2017 and 2016, the Company had income taxes receivable (payable) of $3,106 and $(747), respectively. The U.S. and foreign components of earnings before income taxes are as follows: 2017 2016 2015 U.S. $ 332,607 $ 313,429 $ 282,774 Foreign (5,701 ) (1,264 ) 1,854 Total $ 326,906 $ 312,165 $ 284,628 A reconciliation of significant differences between the reported amount of income tax expense and the expected amount of income tax expense that would result from applying the U.S. federal statutory income tax rate of 35 percent to income before taxes is as follows: 2017 2016 2015 Income tax expense at U.S. federal statutory rate $ 114,417 $ 109,257 $ 99,620 Tax adjustment related to REIT (a) (109,294 ) (101,868 ) (92,073 ) State and local income taxes, net of federal income tax benefit 1,193 1,481 1,180 Book expenses not deductible for tax purposes 2,635 2,465 2,117 Stock-based compensation (121 ) 169 66 Valuation allowance (b) 3,953 2,340 13,818 Rate change (c) (466 ) (19 ) 90 Undistributed earnings of foreign subsidiaries (d) 1,363 — — Minimum tax credit refundable (e) (4,108 ) — — Other differences, net (f) (342 ) (469 ) (2,760 ) Income tax expense $ 9,230 $ 13,356 $ 22,058 (a) Includes dividend paid deduction of $110,442, $102,888 and $83,730 for the tax years ended December 31, 2017, 2016 and 2015, respectively. (b) In May of 2015, Puerto Rico’s “Act 72 of 2015” was signed into law. Under the enacted legislation, significant changes to the 2011 Internal Revenue Code rendered the Company’s tax planning strategy to provide a source of taxable income to support recognition of deferred tax assets in Puerto Rico no longer feasible. As a result, for the years ended December 31, 2017, 2016 and 2015, a non-cash valuation allowance of $3,953, $2,340 and $13,818, respectively, was recorded to income tax expense due to our limited ability to utilize the Puerto Rico deferred tax assets in future years. (c) Under the TCJA, the U.S. corporate income tax rate was lowered from 35% to 21%. As a result, a non-cash benefit of $466 to income tax expense was recorded for the reduction of the U.S. net deferred tax liability. (d) In prior periods, the undistributed earnings of our Canadian subsidiaries were designated as permanently reinvested. As of December 31, 2017, however, management did not assert that the undistributed earnings of our Canadian subsidiaries will be permanently reinvested. During the current year, we recognized a deferred tax charge of $1,363 for future foreign withholding taxes related to undistributed earnings. (e) Under the TCJA, the corporate alternative minimum tax was repealed and any minimum tax carryforwards not utilized become fully refundable in 2021. The Company does not expect to utilize its minimum tax credit carryforward. As a result, a cash benefit of $4,108 to income tax expense was recorded. (f) Upon enactment, the TCJA includes a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings, net of foreign tax credits. As a result, a cash charge of $736 to income tax expense was recorded. The tax effect of temporary differences that give rise to significant portions of the deferred tax assets and (liabilities) are presented below: 2017 2016 Deferred tax assets: Allowance for doubtful accounts $ 709 $ 551 Accrued liabilities not deducted for tax purposes 3,648 4,574 Asset retirement obligation 124 116 Net operating loss carry forwards 18,617 14,835 Tax credit carry forwards 153 153 Charitable contributions carry forward 7 6 Property, plant and equipment 2,300 1,424 Investment in partnerships 240 320 Gross deferred tax assets 25,798 21,979 Less: valuation allowance (20,120 ) (16,167 ) Net deferred tax assets 5,678 5,812 Deferred tax liabilities: Intangibles (5,199 ) — Undistributed earnings of foreign subsidiaries (1,363 ) (6,091 ) Gross deferred tax liabilities (6,562 ) (6,091 ) Net deferred tax liabilities $ (884 ) $ (279 ) As of December 31, 2017, we have approximately $229,118 of U.S. net operating loss carry forwards to offset future taxable income. There is no Internal Revenue Code §382 limitation. These carry forwards expire between 2029 through 2032. In addition, we have $4,799 of various credits available to offset future U.S. federal income tax. Under the TCJA, the corporate alternative minimum tax was repealed and any minimum tax credit carryforwards not utilized become fully refundable in 2021. We do not expect to utilize our minimum tax credit of $4,108 before 2021. As of December 31, 2017 we have approximately $649,401 of state net operating loss carry forwards before valuation allowances. These state net operating losses are available to reduce future taxable income and expire at various times and amounts. In addition, we have $211 of various credits available to offset future state income tax. There was no valuation allowance related to state net operating loss carry forwards as of December 31, 2017 and 2016. There were no net changes in the total state valuation allowance for the years ended December 31, 2017 and 2016. During 2017, we generated $9,568 of Puerto Rico net operating losses. As of December 31, 2017, we had approximately $45,748 of Puerto Rico net operating loss carry forwards before valuation allowances. These Puerto Rico net operating losses are available to offset future taxable income. These carry forwards expire between 2018 and 2027. In addition, we have $153 of alternative minimum tax credits available to offset future Puerto Rico income tax. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income in those jurisdictions during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carry back and carry forward periods), projected future taxable income, and tax-planning strategies in making this assessment. In order to fully realize the deferred tax assets, the Company will need to generate future taxable income before the expiration of the carry forwards governed by the tax code. Based on the current level of pretax earnings and significant changes in Puerto Rico tax legislation, the Company will not generate the minimum amount of future taxable income to support the realization of the deferred tax assets. As a result, management has determined that a valuation allowance related to Puerto Rico net operating loss carry forwards and other deferred tax assets is necessary. The valuation allowance for these deferred tax assets as of December 31, 2017 and 2016 was $20,120 and $16,167, respectively. The net change in the total valuation allowance for the years ended December 31, 2017 and 2016 was an increase of $3,953 and $2,340, respectively. The amount of the deferred tax asset considered realizable, however, could be adjusted in the near term if estimates of future taxable income during the carry forward period increase. As of December 31, 2017, the Company has accumulated undistributed earnings generated by our foreign subsidiaries of approximately $38,213, of which $29,018 is subject to the one-time transition tax on foreign earnings required by the TCJA or has otherwise been previously taxed. In prior periods, management considered these earning to be indefinitely reinvested outside of the U.S. As of December 31, 2017, management does not designate these earnings as permanently reinvested. We have recognized a deferred tax liability of approximately $1,363 related to foreign withholding taxes on these earnings. Under ASC 740 Income Taxes Balance as of December 31, 2015 $ — Additions for tax positions related to current year 696 Additions for tax positions related to prior years 76 Reductions for tax positions related to prior years — Lapse of statute of limitations — Settlements — Balance as of December 31, 2016 $ 772 Additions for tax positions related to current year 1,122 Additions for tax positions related to prior years 173 Reductions for tax positions related to prior years — Lapse of statute of limitations — Settlements — Balance as of December 31, 2017 $ 2,067 Included in the balance of unrecognized benefits at December 31, 2017 is $2,067 of tax benefits that, if recognized in future periods, would impact our effective tax rate. During the years ended December 31, 2017 and 2016, we recognized interest and penalties of $213 and $18, respectively, as a component of income tax expense in connection with our liabilities related to uncertain tax positions. Within the next twelve months, we do not expect to decrease our unrecognized tax benefits as a result of the expiration of statute of limitations. We are subject to income taxes in the U.S. and nearly all states. In addition, the Company is subject to income taxes in Canada and the Commonwealth of Puerto Rico. We are no longer subject to U.S federal income tax examinations by tax authorities for years prior to 2013, or for any U.S. state income tax audit prior to 2009. The Internal Revenue Service has completed a review of the 2013 income tax return. With respect to Canada and Puerto Rico, we are no longer subject to income tax audits for years before 2014 and 2013, respectively.

The U.S. and foreign components of earnings before income taxes are as follows: 2017 2016 2015 U.S. $ 332,989 $ 313,801 $ 283,107 Foreign (5,701 ) (1,264 ) 1,854 Total $ 327,288 $ 312,537 $ 284,961 A reconciliation of significant differences between the reported amount of income tax expense and the expected amount of income tax expense that would result from applying the U.S. federal statutory income tax rate of 35 percent to income before taxes is as follows: 2017 2016 2015 Income tax expense at U.S. federal statutory rate $ 114,551 $ 109,388 $ 99,736 Tax adjustment related to REIT (a) (109,294 ) (101,999 ) (92,189 ) State and local income taxes, net of federal income tax benefit 1,193 1,481 1,180 Book expenses not deductible for tax purposes 2,635 2,465 2,117 Stock-based compensation (121 ) 169 66 Valuation allowance (b) 3,953 2,340 13,818 Rate Change (c) (466 ) (19 ) 90 Undistributed earnings of foreign subsidiaries (d) 1,363 — — Minimum tax credit refundable (e) (4,108 ) — — Other differences, net (f) (476 ) (469 ) (2,760 ) Income tax expense $ 9,230 $ 13,356 $ 22,058 (a) Includes dividend paid deduction of $110,824, $102,888 and $83,866 for the tax years ended December 31, 2017, 2016 and 2015, respectively. (b) In 2015, Puerto Rico’s “Act 72 of 2015” was signed into law. Under the enacted legislation, significant changes to the 2011 Internal Revenue Code rendered the Company’s tax planning strategy to provide a source of taxable income to support recognition of deferred tax assets in Puerto Rico no longer feasible. As a result, for the years ended December 31, 2017, 2016 and 2015, a non-cash valuation allowance of $3,953, $2,340 and $13,818, respectively, was recorded to income tax expense due to our limited ability to utilize the Puerto Rico deferred tax assets in future years. (c) Under the TCJA, the U.S. corporate income tax rate was lowered from 35% to 21%. As a result, a non-cash benefit of $466 to income tax expense was recorded for the reduction of the U.S. net deferred tax liability. (d) In prior periods, the undistributed earnings of our Canadian subsidiaries were designated as permanently reinvested. As of December 31, 2017, however, management did not assert that the undistributed earnings of our Canadian subsidiaries will be permanently reinvested. During the current year, we recognized a deferred tax charge of $1,363 for future foreign withholding taxes related to undistributed earnings. (e) Under the TCJA, the corporate alternative minimum tax was repealed and any minimum tax carryforwards not utilized become fully refundable in 2021. The Company does not expect to utilize its minimum tax credit carryforward. As a result, a cash benefit of $4,108 to income tax expense was recorded. (f) Upon enactment, the TCJA includes a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings, net of foreign tax credits. As a result, a cash charge of $736 to income tax expense was recorded. The tax effect of temporary differences that give rise to significant portions of the deferred tax assets and (liabilities) are presented below: 2017 2016 Deferred tax assets: Allowance for doubtful accounts $ 709 $ 551 Accrued liabilities not deducted for tax purposes 3,648 4,574 Asset retirement obligation 124 116 Net operating loss carry forwards 18,617 14,835 Tax credit carry forwards 153 153 Charitable contributions carry forward 7 6 Property, plant and equipment 2,300 1,424 Investment in partnership 240 320 Gross deferred tax assets 25,798 21,979 Less: valuation allowance (20,120 ) (16,167 ) Net deferred tax assets 5,678 5,812 Deferred tax liabilities: Intangibles (5,199 ) — Undistributed earnings of foreign subsidiaries (1,363 ) (6,091 ) Gross deferred tax liabilities (6,562 ) (6,091 ) Net deferred tax liabilities $ (884 ) $ (279 ) As of December 31, 2017, we have approximately $92,985 of U.S. net operating loss carry forwards to offset future taxable income. None of this amount is subject to an Internal Revenue Code §382 limitation. These carry forwards expire between 2029 and 2032. As of December 31, 2017, the Company has $14,771 of various tax credits available to offset future U.S. federal taxable income. Also, the Company recognized a $4,108 tax benefit related to its minimum tax credit carryforwards which we do not expect to utilize before 2021. As of December 31, 2017, we have approximately $611,680 state net operating loss carry forwards before valuation allowances. These state net operating losses are available to reduce future taxable income and expire at various times and amounts. In addition, we have $211 of various credits available to offset future state income tax. There was no valuation allowance related to state net operating loss carry forwards as of December 31, 2017 and December 31, 2016. There were no net changes in the total state valuation allowance for the years ended December 31, 2017 and 2016. During 2017 we generated $9,568 of Puerto Rico net operating losses. As of December 31, 2017, we had approximately $45,748 of Puerto Rico net operating loss carry forwards before valuation allowances. These Puerto Rico net operating losses are available to offset future taxable income. These carry forwards expire between 2018 and 2027. In addition, we have $153 of alternative minimum tax credits available to offset future Puerto Rico income tax. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income in those jurisdictions during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carry back and carry forward periods), projected future taxable income, and tax-planning strategies in making this assessment. In order to fully realize the deferred tax assets, the Company will need to generate future taxable income before the expiration of the carry forwards governed by the tax code. Based on the current level of pretax earnings and significant changes in Puerto Rico tax legislation, the Company will not generate the minimum amount of future taxable income to support the realization of the deferred tax assets. As a result, management has determined that a valuation allowance related to Puerto Rico net operating loss carry forwards and other deferred tax assets is necessary. The valuation allowance for these deferred tax assets as of December 31, 2017 and 2016 was $20,120 and $16,167, respectively. The net change in the total valuation allowance for the years ended December 31, 2017 and 2016 was an increase of $3,953 and $2,340, respectively. The amount of the deferred tax asset considered realizable, however, could be adjusted in the near term if estimates of future taxable income during the carry forward period increase. As of December 31, 2017, the Company has accumulated undistributed earnings generated by our foreign subsidiaries of approximately $38,213, of which $29,018 is subject to the one-time transition tax on foreign earnings required by the TCJA or has otherwise been taxed. In prior periods management considered these earnings to be indefinitely reinvested outside of the U.S. As of December 31, 2017, management does not designate these earnings as permanently reinvested. We have recognized a deferred tax liability of approximately $1,363 related to foreign withholding taxes on these earnings. Under ASC 740 Income Taxes Balance as of December 31, 2015 $ — Additions for tax positions related to current year 696 Additions for tax positions related to prior years 76 Reductions for tax positions related to prior years — Lapse of statute of limitations — Settlements — Balance as of December 31, 2016 $ 772 Additions for tax positions related to current year 1,122 Additions for tax positions related to prior years 173 Reductions for tax positions related to prior years — Lapse of statute of limitations — Settlements — Balance as of December 31, 2017 $ 2,067 Included in the balance of unrecognized benefits at December 31, 2017 is $2,067 of tax benefits that, if recognized in future periods, would impact our effective tax rate. During the year ended December 31, 2017 and 2016, we recognized interest and penalties of $213 and $18, respectively, as a component of income tax expense in connection with our liabilities related to uncertain tax positions. Within the next twelve months, we do not expect to decrease our unrecognized tax benefits as a result of the expiration of statute of limitations. We are subject to income taxes in the U.S. and nearly all states. In addition, the Company is subject to income taxes in Canada and the Commonwealth of Puerto Rico. We are no longer subject to U.S federal income tax examinations by tax authorities for years prior to 2013, or for any U.S. state income tax audit prior to 2009. The IRS has completed a review of the 2013 income tax return. With respect to Canada and Puerto Rico, we are no longer subject to income tax audits for years before 2014 and 2013, respectively.

Equity [Abstract]
Stockholders' Equity	(13) Stockholders’ Equity On July 16, 1999, the Board of Directors designated 5,720 shares of the 1,000,000 shares of previously undesignated preferred stock, par value $.001, as Series AA preferred stock, which shares were subsequently exchanged on a one for one basis in the REIT conversion. The Series AA preferred stock ranks senior to the Class A common stock and Class B common stock with respect to dividends and upon liquidation. Holders of Series AA preferred stock are entitled to receive, on a pari passu basis, dividends at the rate of $15.95 per share per quarter when, as and if declared by the Board of Directors. The Series AA preferred stock is entitled to receive, on a pari passu basis, $638 plus a further amount equal to any dividend accrued and unpaid to the date of distribution before any payments are made or assets distributed to the Class A common stock or Class B stock upon voluntary or involuntary liquidation, dissolution or winding up of the Company. The liquidation value of the outstanding Series AA preferred stock at December 31, 2017 was $3,649. The Series AA preferred stock is entitled to one vote per share. All of the outstanding shares of common stock are fully paid and nonassessable. In the event of the liquidation or dissolution of the Company, following any required distribution to the holders of outstanding shares of preferred stock, the holders of common stock are entitled to share pro rata in any balance of the corporate assets available for distribution to them. The Company may pay dividends if, when and as declared by the Board of Directors from funds legally available therefore, subject to the restrictions set forth in the Company’s existing indentures and the senior credit facility. Subject to the preferential rights of the holders of any class of preferred stock, holders of shares of common stock are entitled to receive such dividends as may be declared by the Company’s Board of Directors out of funds legally available for such purpose. No dividend may be declared or paid in cash or property on any share of either class of common stock unless simultaneously the same dividend is declared or paid on each share of the other class of common stock, provided that, in the event of stock dividends, holders of a specific class of common stock shall be entitled to receive only additional shares of such class. The rights of the Class A and Class B common stock are equal in all respects, except holders of Class B common stock have ten votes per share on all matters in which the holders of common stock are entitled to vote and holders of Class A common stock have one vote per share on such matters. The Class B common stock will convert automatically into Class A common stock upon the sale or transfer to persons other than permitted transferees (as defined in the Company’s certificate of incorporation, as amended). On December 11, 2014, the Company announced that its Board of Directors authorized the repurchase of up to $250,000 of the Company’s Class A common stock (the “repurchase program”). There were no repurchases under the repurchase program which expired on June 30, 2016.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock Compensation Plans	(14) Stock Compensation Plans Equity Incentive Plan. Lamar’s 1996 Equity Incentive Plan, as amended, (the “1996 Plan”) has reserved 15.5 million shares of common stock for issuance to directors and employees, including options granted and common stock reserved for issuance under its performance-based incentive program. Options granted under the 1996 Plan expire ten years from the grant date with vesting terms ranging from three to five years which primarily includes 1) options that vest in one-fifth increments beginning on the grant date and continuing on each of the first four anniversaries of the grant date and 2) options that cliff-vest on the fifth anniversary of the grant date. All grants are made at fair market value based on the closing price of our Class A common stock as reported on the NASDAQ Global Select Market on the date of grant. In February 2013, the 1996 Plan was amended to eliminate the provision that limited the amount of Class A common stock, including shares retained from an award, that could be withheld to satisfy tax withholding obligations to the minimum tax obligations required by law (except with respect to option awards). In accordance with ASC 718, Compensation – Stock Compensation We use a Black-Scholes-Merton option pricing model to estimate the fair value of share-based awards. The Black-Scholes-Merton option pricing model incorporates various highly subjective assumptions, including expected term and expected volatility. We have reviewed our historical pattern of option exercises and have determined that meaningful differences in option exercise activity existed among vesting schedules. Therefore, for all stock options granted after January 1, 2006, we have categorized these awards into two groups of vesting 1) 5-year cliff vest and 2) 4-year graded vest, for valuation purposes. We have determined there were no meaningful differences in employee activity under our ESPP due to the nature of the plan. We estimate the expected term of options granted using an implied life derived from the results of a hypothetical mid-point settlement scenario, which incorporates our historical exercise, expiration and post-vesting employment termination patterns, while accommodating for partial life cycle effects. We believe these estimates will approximate future behavior. We estimate the expected volatility of our Class A common stock at the grant date using a blend of 90% historical volatility of our Class A common stock and 10% implied volatility of publicly traded options with maturities greater than six months on our Class A common stock as of the option grant date. Our decision to use a blend of historical and implied volatility was based upon the volume of actively traded options on our common stock and our belief that historical volatility alone may not be completely representative of future stock price trends. Our risk-free interest rate assumption is determined using the Federal Reserve nominal rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. We assumed an expected dividend yield of 5%. We estimate option forfeitures at the time of grant and periodically revise those estimates in subsequent periods if actual forfeitures differ from those estimates. We record stock-based compensation expense only for those awards expected to vest using an estimated forfeiture rate based on our historical forfeiture data. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions used: Grant Year Dividend Yield Expected Volatility Risk Free Interest Rate Expected Lives 2017 5% 45% 2% 6 2016 5% 45% 2% 6 2015 5% 45% 2% 6 Information regarding the 1996 Plan for the year ended December 31, 2017 is as follows: Shares Weighted Average Exercise Price Weighted Average Contractual Life Outstanding, beginning of year 1,567,426 $ 39.78 Granted 92,500 73.10 Exercised (554,049 ) 36.65 Forfeited (5,000 ) 68.98 Expired (1,000 ) 73.44 Outstanding, end of year 1,099,877 44.00 5.32 Exercisable at end of year 927,277 39.95 4.72 At December 31, 2017 there was $2,490 of unrecognized compensation cost related to stock options granted which is expected to be recognized over a weighted-average period of 1.41 years. Shares available for future stock option and restricted share grants to employees and directors under existing plans were 1,171,906 at December 31, 2017. The aggregate intrinsic value of options outstanding as of December 31, 2017 was $33,265, and the aggregate intrinsic value of options exercisable was $31,794. Total intrinsic value of options exercised was $20,954 for the year ended December 31, 2017. Stock Purchase Plan. In 2009 our Board of Directors adopted a new employee stock purchase plan, the 2009 Employee Stock Purchase Plan (the “2009 ESPP”), which was approved by our shareholders on May 28, 2009. The 2009 ESPP reserved 588,154 shares of Class A common stock for issuance to our employees, which included 88,154 shares of Class A common stock that had been available for issuance under our 2000 Employee Stock Purchase Plan (the “ 2000 ESPP”). The 2000 ESPP was terminated following the issuance of all shares that were subject to the offer that commenced under the 2000 ESPP on January 1, 2009 and ended June 30, 2009. The terms of the 2009 ESPP are substantially the same as the 2000 ESPP. The number of shares of Class A common stock available under the 2009 ESPP was automatically increased by 82,823 shares on January 1, 2017 pursuant to the automatic increase provisions of the 2009 ESPP. The following is a summary of 2009 ESPP share activity for the year ended December 31, 2017: Shares Available for future purchases, January 1, 2017 250,573 Additional shares reserved under 2009 ESPP 82,823 Purchases (107,978 ) Available for future purchases, December 31, 2017 225,418 Performance-based compensation. Unrestricted shares of our Class A common stock may be awarded to key officers and employees under our 1996 Plan based on certain Company performance measures for fiscal 2017. The number of shares to be issued, if any, are dependent on the level of achievement of these performance measures as determined by the Company’s Compensation Committee based on our 2017 results and were issued in the first quarter of 2018. The shares subject to these awards can range from a minimum of 0% to a maximum of 100% of the target number of shares depending on the level at which the goals are attained. Based on the Company’s performance measures achieved through December 31, 2017, the Company has accrued $4,495 as compensation expense related to these agreements.

Fair Value of Financial Instruments	(18) Fair Value of Financial Instruments At December 31, 2017 and 2016, the Company’s financial instruments included cash and cash equivalents, marketable securities, accounts receivable, investments, accounts payable and borrowings. The fair values of cash and cash equivalents, accounts receivable, accounts payable and short-term borrowings and current portion of long-term debt approximated carrying values because of the short-term nature of these instruments. Investments and initial recognition of asset retirement obligations are reported at fair values. Fair values for investments held at cost are not readily available, but are estimated to approximate fair value. The estimated fair value of the Company’s long term debt (including current maturities) was $2,666,875, which exceeded both the gross and carrying amount of $2,585,409 as of December 31, 2017. The majority of the fair value is determined using observed prices of publicly traded debt (level 1 in the fair value hierarchy) and the remaining is valued based on quoted prices for similar debt (level 2 in the fair value hierarchy).

Nature of Business	(a) Nature of Business Lamar Advertising Company (the Company) is engaged in the outdoor advertising business, operating approximately 149,900 billboard advertising displays in 45 states, Canada and Puerto Rico. The Company’s operating strategy is to be the leading provider of outdoor advertising services in the markets it serves. In addition, the Company operates a logo sign business in 22 states throughout the United States and the province of Ontario, Canada and operates approximately 53,300 transit advertising displays in 21 states and Canada. Logo signs are erected pursuant to state-awarded service contracts on public rights-of-way near highway exits and deliver brand name information on available gas, food, lodging and camping services. Included in the Company’s logo sign business are tourism signing contracts. The Company provides transit advertising in airport terminals, on bus shelters, benches and buses in the markets it serves. The Company operates as a Real Estate Investment Trust (“REIT”) for U.S. federal income tax purposes and generally will not be subject to federal income taxes on its income and gains that the Company distributes to its stockholders, including the income derived from advertising rental revenue. However, even as a REIT, the Company will remain obligated to pay income taxes on earnings from the assets of its taxable REIT subsidiaries (“TRSs”). In addition, the Company’s foreign assets and operations continue to be subject to taxation in the foreign jurisdictions where those assets are held or those operations are conducted.
Principles of Consolidation	(b) Principles of Consolidation The accompanying consolidated financial statements include Lamar Advertising Company, its wholly owned subsidiary, Lamar Media Corp. (Lamar Media), and its majority-owned subsidiaries. All inter-company transactions and balances have been eliminated in consolidation. An operating segment is a component of an enterprise: • that engages in business activities from which it may earn revenues and incur expenses; • whose operating results are regularly reviewed by the enterprise’s chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance; and • for which discrete financial information is available. We define the term ‘chief operating decision maker’ to be our executive management group, which consist of our Chief Executive Officer, President and Chief Financial Officer. Currently, all operations are reviewed on a consolidated basis for budget and business plan performance by our executive management group. Additionally, operational performance at the end of each reporting period is viewed in the aggregate by our management group. Any decisions related to changes in invested capital, personnel, operational improvement or training, or to allocate other company resources are made based on the combined results. We operate in a single operating and reporting segment, advertising. We rent advertising space on billboards, buses, shelters, benches, logo plates and in airport terminals.
Property, Plant and Equipment	(c) Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets.
Goodwill and Intangible Assets	(d) Goodwill and Intangible Assets Goodwill is subject to an annual impairment test. The Company designated December 31 as the date of its annual goodwill impairment test. Impairment testing involves various estimates and assumptions, which could vary, and an analysis of relevant market data and market capitalization. If industry and economic conditions deteriorate, the Company may be required to assess goodwill impairment before the next annual test, which could result in impairment charges. The Company is required to identify its reporting units and determine the carrying value of each reporting unit. The Company has identified two reporting units, Billboard operations and Logo operations, by assigning the assets and liabilities, including the existing goodwill and intangible assets, to those reporting units. The Company is required to determine the fair value of each reporting unit and compare it to the carrying amount of the reporting unit. To the extent the carrying amount of a reporting unit exceeds the fair value of the reporting unit, the Company would be required to book an impairment loss. The fair value of each reporting unit exceeded its carrying amount at its annual impairment test date on December 31, 2017 and 2016; therefore, the Company was not required to recognize an impairment loss. Intangible assets, consisting primarily of site locations, customer lists and contracts, and non-competition agreements are amortized using the straight-line method over the assets estimated useful lives, generally from 2 to 15 years.
Impairment of Long-Lived Assets	(e) Impairment of Long-Lived Assets Long-lived assets, such as property, plant and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset or asset group before interest expense. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset or asset group. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the balance sheet.
Acquisitions	(f) Acquisitions The Company accounts for transactions that meet the definition of a business and group asset purchases as acquisitions. For transactions that meet the definition of a business combination, the Company allocates the purchase price, including any contingent consideration, to the assets acquired and the liabilities assumed at their estimated fair values as of the date of the acquisition with any excess of the purchase price paid over the estimated fair value of net assets acquired recorded as goodwill. For transactions that meet the definition of asset group purchases, the Company allocates the purchase price to the assets acquired and the liabilities assumed at their estimated fair values as of the date of the acquisition. If a transaction is determined to be a group of assets, any direct acquisition costs are capitalized. Transaction costs for transactions determined to be a business combination are expensed as incurred. The fair value of the assets acquired and liabilities assumed is typically determined by using either estimates of replacement costs or discounted cash flow valuation methods. When determining the fair value of tangible assets acquired, the Company must estimate the cost to replace the asset with a new asset, adjusted for an estimated reduction in fair value due to age of the asset, and the economic useful life. When determining the fair value of intangible assets acquired, the Company must estimate the applicable discount rate and the timing and amount of future cash flows. The determination of the final purchase price and the acquisition-date fair value of identifiable assets acquired and liabilities assumed may extend over more than one period and result in adjustments to the preliminary estimate recognized in the prior period financial statements. Effective October 1, 2016, the Company changed its accounting for business combinations, as further discussed in note 20 to the consolidated financial statements.
Deferred Income	(g) Deferred Income Deferred income consists principally of advertising revenue invoiced in advance. Deferred advertising revenue is recognized in income over the term of the contract.
Revenue Recognition	(h) Revenue Recognition The Company recognizes outdoor advertising revenue on an accrual basis ratably over the term of the contracts. Production revenue and the related expense for the advertising copy are recognized upon completion of the sale. The Company engages in barter transactions where the Company trades advertising space for goods and services. The Company recognizes revenues and expenses from barter transactions at fair value, which is determined based on the Company’s own historical practice of receiving cash for similar advertising space from buyers unrelated to the party in the barter transaction. The amount of revenue and expense recognized for advertising barter transactions is as follows: 2017 2016 2015 Net revenues $ 8,469 $ 8,051 $ 7,956 Direct advertising expenses $ 3,603 $ 3,559 $ 3,137 General and administrative expenses $ 4,332 $ 4,067 $ 4,407
Income Taxes	(i) Income Taxes As a REIT, the Company is generally not subject to federal income taxes on income and gains distributed to the Company’s stockholders. However, the Company remains obligated to pay income taxes on earnings from domestic TRSs. In addition, the Company’s foreign assets and operations continue to be subject to taxation in the foreign jurisdictions where those assets are held or where those operations are conducted, including those designated as Qualified REIT Subsidiaries, or QRSs, for federal income tax purposes. Accordingly, the consolidated financial statements reflect provisions for federal, state, local and foreign income taxes. The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, as well as operating loss and tax credit carryforwards. The Company measures deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carry forwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities as a result of a change in tax rates is recognized in income in the period that includes the enactment date.
Dividends/Distributions	(j) Dividends/Distributions As a REIT, the Company must annually distribute to its stockholders an amount equal to at least 90% of its REIT taxable income (determined before the deduction for distributed earnings and excluding any net capital gain). During the year ended December 31, 2017, the Company declared distributions of $325,462 or $3.32 per share, including paid distributions of $243,928 or $2.49 per share. During the years ended 2016 and 2015, the Company declared and paid distributions of its REIT taxable income of an aggregate of $293,600 or $3.02 per share and $265,145 or $2.75 per share, respectively. The amount, timing and frequency of future distributions will be at the sole discretion of the Board of Directors and will be declared based upon various factors, a number of which may be beyond the Company’s control, including the financial condition and operating cash flows, the amount required to maintain REIT status and reduce any income and excise taxes that the Company otherwise would be required to pay, limitations on distributions in its existing and future debt instruments, the Company’s ability to utilize net operating losses (“NOLs”) to offset, in whole or in part, the Company’s distribution requirements, limitations on its ability to fund distributions using cash generated through its TRSs and other factors that the Board of Directors may deem relevant. During the years ended December 31, 2017, 2016 and 2015, the Company accrued or paid cash dividend distributions to holders of its Series AA Preferred Stock of $365 or $63.80 per share.
Earnings Per Share	(k) Earnings Per Share The calculation of basic earnings per share excludes any dilutive effect of stock options, while diluted earnings per share includes the dilutive effect of stock options. For the years ended December 31, 2017, 2016 and 2015 there were no dilutive shares excluded from the calculation.
Share Based Compensation	(l) Stock Based Compensation Compensation expense for share-based awards is recognized based on the grant date fair value of those awards. Stock-based compensation expense includes an estimate for pre-vesting forfeitures and is recognized over the requisite service periods of the awards on a straight-line basis, which is generally commensurate with the vesting term. Non-cash compensation expense recognized during the years ended December 31, 2017, 2016, and 2015 were $9,599, $28,560 and $25,890, respectively. The $9,599 expensed during the year ended December 31, 2017 consists of (i) $3,636 related to stock options, (ii) $5,589 related to stock grants made under the Company’s performance-based stock incentive program in 2017 and (iii) $374 related to stock awards to directors. See Note 14 for information on the assumptions used to calculate the fair value of stock-based compensation.
Cash and Cash Equivalents	(m) Cash and Cash Equivalents The Company considers all highly-liquid investments with original maturities of three months or less to be cash equivalents.
Foreign Currency Translation	(n) Foreign Currency Translation Local currencies generally are considered the functional currencies outside the United States. Assets and liabilities for operations in local-currency environments are translated at year-end exchange rates. Income and expense items are translated at average rates of exchange prevailing during the year. Foreign currency translation adjustments are recorded as a component of other comprehensive income (loss) in the Consolidated Statements of Income and Comprehensive Income and as a component of accumulated comprehensive income (loss) in the Consolidated Statements of Stockholders’ Equity.
Asset Retirement Obligations	(o) Asset Retirement Obligations The Company is required to record the fair value of obligations associated with the retirement of tangible long-lived assets in the period in which it is incurred. The liability is capitalized as part of the related long-lived asset’s carrying amount. Over time, accretion of the liability is recognized as an operating expense and the capitalized cost is depreciated over the expected useful life of the related asset. The Company’s asset retirement obligations relate primarily to the dismantlement, removal, site reclamation and similar activities of its leased properties.
Use of Estimates	(p) Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Comprehensive Income	(q) Comprehensive Income Total comprehensive income is presented in the Consolidated Statements of Income and Comprehensive Income and the components of accumulated comprehensive income (loss) are presented in the Consolidated Statements of Stockholders’ Equity. Comprehensive income (loss) is composed of foreign currency translation effects.
Fair Value Measurements	(r) Fair Value Measurements The Company determines the fair value of its financial instruments using the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
Subsequent Events	(s) Subsequent Events The Company has performed an evaluation of subsequent events through the date on which the financial statements are issued.

Schedule of Effective Income Tax Rate Reconciliation	A reconciliation of significant differences between the reported amount of income tax expense and the expected amount of income tax expense that would result from applying the U.S. federal statutory income tax rate of 35 percent to income before taxes is as follows: 2017 2016 2015 Income tax expense at U.S. federal statutory rate $ 114,417 $ 109,257 $ 99,620 Tax adjustment related to REIT (a) (109,294 ) (101,868 ) (92,073 ) State and local income taxes, net of federal income tax benefit 1,193 1,481 1,180 Book expenses not deductible for tax purposes 2,635 2,465 2,117 Stock-based compensation (121 ) 169 66 Valuation allowance (b) 3,953 2,340 13,818 Rate change (c) (466 ) (19 ) 90 Undistributed earnings of foreign subsidiaries (d) 1,363 — — Minimum tax credit refundable (e) (4,108 ) — — Other differences, net (f) (342 ) (469 ) (2,760 ) Income tax expense $ 9,230 $ 13,356 $ 22,058 (a) Includes dividend paid deduction of $110,442, $102,888 and $83,730 for the tax years ended December 31, 2017, 2016 and 2015, respectively. (b) In May of 2015, Puerto Rico’s “Act 72 of 2015” was signed into law. Under the enacted legislation, significant changes to the 2011 Internal Revenue Code rendered the Company’s tax planning strategy to provide a source of taxable income to support recognition of deferred tax assets in Puerto Rico no longer feasible. As a result, for the years ended December 31, 2017, 2016 and 2015, a non-cash valuation allowance of $3,953, $2,340 and $13,818, respectively, was recorded to income tax expense due to our limited ability to utilize the Puerto Rico deferred tax assets in future years. (c) Under the TCJA, the U.S. corporate income tax rate was lowered from 35% to 21%. As a result, a non-cash benefit of $466 to income tax expense was recorded for the reduction of the U.S. net deferred tax liability. (d) In prior periods, the undistributed earnings of our Canadian subsidiaries were designated as permanently reinvested. As of December 31, 2017, however, management did not assert that the undistributed earnings of our Canadian subsidiaries will be permanently reinvested. During the current year, we recognized a deferred tax charge of $1,363 for future foreign withholding taxes related to undistributed earnings. (e) Under the TCJA, the corporate alternative minimum tax was repealed and any minimum tax carryforwards not utilized become fully refundable in 2021. The Company does not expect to utilize its minimum tax credit carryforward. As a result, a cash benefit of $4,108 to income tax expense was recorded. (f) Upon enactment, the TCJA includes a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings, net of foreign tax credits. As a result, a cash charge of $736 to income tax expense was recorded.
