Basis Of Presentation [Abstract]
Foreign Currency Translation	Foreign Currency Translation The functional currency for the Company’s Central American subsidiaries is the U.S. dollar. Monetary assets and liabilities of such subsidiaries which are not denominated in U.S. dollars are remeasured at exchange rates in effect at the balance sheet date, and revenues and expenses are remeasured at monthly average rates prevailing during the year. Unrealized translation gains and losses are reported as other income (expense), net in the Consolidated Statement of Operations. All assets and liabilities of foreign subsidiaries that do not utilize the U.S. dollar as its functional currency are translated at period-end rates of exchange, while revenues and expenses are translated at monthly average rates of exchange prevailing during the period. Unrealized remeasurement gains and losses are reported as foreign currency translation adjustments through Accumulated Other Comprehensive Loss in the accompanying Consolidated Statement of Shareholders’ Deficit.
Intercompany Loans	Intercompany Loans In accordance with ASC 830, the Company remeasures foreign denominated intercompany loans with the corresponding change in the balance being recorded in Other income (expense), net in the Consolidated Statement of Operations as settlement is anticipated or planned in the foreseeable future. The Company recorded an $18.4 million gain and a $3.2 million loss on the remeasurement of intercompany loans for the three months ended September 30, 2017 and 2016, respectively, and an $11.6 million gain and an $89.0 million gain on the remeasurement of intercompany loans for the nine months ended September 30, 2017 and 2016, respectively. As of September 30, 2017, the outstanding balance under the intercompany loan agreement with our Brazilian subsidiary was $433.3 million.
Accounting Pronouncements Recently Adopted	Accounting Pronouncements Recently Adopted In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business. The standard provides guidance to help entities determine whether transactions should be accounted for as acquisitions or disposals of assets or businesses. ASU 2017-01 provides revised guidance to determine when an acquisition meets the definition of a business or should be accounted for as an asset acquisition, likely resulting in more acquisitions being accounted for as asset acquisitions as opposed to business combinations. The Company adopted this standard prospectively effective January 1, 2017. Under this update, substantially all of the Company’s acquisitions are expected to qualify for asset acquisition treatment under ASC 360, Property, Plant, and Equipment, rather than business combination treatment under ASC 805 Business Combinations. For asset acquisitions, external, direct transaction costs will be capitalized as a component of the cost of the asset acquired, while internal costs related to the asset acquisition will continue to be expensed as incurred. Additionally, earnout liabilities will be recognized at the time when the contingency is resolved or becomes payable and will increase the cost basis of the assets acquired. The adoption of ASU 2017-01 did not have a material impact on the Company’s unaudited consolidated financial statements and related disclosures.
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted In May 2014, the FASB released an updated standard regarding the recognition of revenue from contracts with customers, exclusive of those contracts within lease accounting. The core principle of the standard is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify the contracts with the customer; (2) identify the performance obligations in the contract; (3) determine the contract price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. This standard is effective for the Company in the first quarter of 2018. Early adoption is permitted. This standard is required to be applied retrospectively to each prior reporting period presented or with the cumulative effect being recognized at the date of initial application. The Company is evaluating the standard and does not expect a material financial statement impact upon adoption since the standard only affects the Company’s site development segment, which represents approximately 6% of the Company’s total revenues. In February 2016, the FASB issued ASU 2016-02, Leases. The standard requires lessees to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments for all leases with a term greater than 12 months. The accounting for lessors remains largely unchanged from existing guidance. This standard is effective for annual and interim periods beginning after December 15, 2018 and requires a modified retrospective transition approach for all leases existing at, or entered into after, the beginning of the earliest comparative period presented. Early adoption is permitted; however, the Company does not currently plan to early adopt. The Company has established a cross functional project plan and is currently assessing the impact of the standard on its consolidated financial statements. The Company expects this guidance to have a material impact on its consolidated balance sheet due to the recognition of right-of-use assets and lease liabilities for its ground leases. The Company does not expect adoption to have a material impact on its consolidated statement of operations, nor does it expect accounting for capital leases to change substantially.
