These unaudited condensed consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC for Interim Reporting. All intercompany transactions, accounts and profits, if any, have been eliminated in the unaudited condensed consolidated financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These unaudited condensed consolidated financial statements do not include all disclosures required by GAAP, therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the more detailed audited consolidated financial statements for the year ended December 31, 2018. The December 31, 2018 condensed consolidated balance sheet was derived from the Company’s audited consolidated financial statements for the year ended December 31, 2018.

Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	2. Recently Adopted Accounting Pronouncements In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). This update permitted entities to reclassify tax effects stranded in accumulated other comprehensive income as a result of tax reform from the Tax Cuts and Jobs Act. The adoption of ASU 2018-02 did not have an impact on the Company’s condensed consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”), to simplify the accounting for share-based payments made to nonemployees. Under ASU 2018-07, In July 2018, the FASB issued ASU 2018-09, Codification Improvements (“ASU 2018-09”). This standard did not prescribe any new accounting guidance, but instead made changes to a variety of topics to clarify, correct errors in, or make minor improvements to the In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASC 842”), which requires lessees to recognize most leases on their balance sheets as a right-of-use asset with a corresponding lease liability. The Company adopted ASC 842 on January 1, 2019 and elected to use the modified retrospective transition method prescribed under ASC 842 to not restate comparative periods in transition and use the effective date of ASC 842 as the date of initial adoption. Additionally, the Company applied the available practical expedient of keeping leases with an initial term of twelve months or less off of the balance sheet. As a result of the adoption of ASC 842 Leases Recently Issued Accounting Pronouncements There have been no other new accounting pronouncements that are expected to have a significant impact on the Company’s condensed consolidated financial statements or notes thereto.

Revenue From Contract With Customer [Abstract]
Revenues	3. Revenues The Company’s primary source of revenue is generated from the production of trade shows and conference events (collectively, “trade shows”), including booth space sales, registration fees and sponsorship fees. The Company recognizes revenue upon completion of each trade show. Trade show and conference events revenues represented approximately 95.2% and 96.1% of total revenues for the three months ended March 31, 2019 and 2018, respectively. Deferred revenues generally consist of booth space sales, registration fees and sponsorship fees that are invoiced prior to the trade show or other event. Current deferred revenues Performance Obligations For the Company’s trade shows and other events, sales are deferred and recognized when performance obligations under the terms of a contract with the Company’s customer are satisfied, which is typically at the completion of a show or event. Revenue is measured as the amount of consideration the Company expects to receive upon completion of performance obligations. For the Company’s other marketing services, sales are deferred and recognized when performance obligations under the terms of a contract with the Company’s customer are satisfied. This generally occurs in the period in which the publications are issued. Revenue is measured as the amount of consideration the Company expects to receive upon completion of performance obligations. The Company applied a practical expedient which allows the exclusion of disclosure Disaggregation of Revenue The Company’s primary sources of revenue are from trade shows, other events and other marketing services. The following table represents revenues disaggregated by type: Three Months Ended March 31, (in millions) 2019 2018 Trade shows $ 116.9 $ 123.7 Other events 13.8 13.0 Other marketing services 6.7 5.5 Total revenues $ 137.4 $ 142.2 Contract Balances Due to the nature of the Company’s revenue from contracts with customers, the Company does not have material contract assets that fall under the scope of ASC Topic 606. Contract liabilities generally consist of booth space sales, registration fees and sponsorship fees that are collected prior to the trade show or other event. The related revenue is recognized upon the completion of the applicable trade show or other event. Contract liabilities are reported on the condensed consolidated balance sheets as deferred revenues. The Company incurs sales commissions costs in connection with sales of booth space, registration fees and sponsorship fees at the Company’s trade shows and events and with sales of advertising for industry publications. The Company’s contracts with customers are generally short term, as sales generally begin up to one year prior to the date of the trade shows and other events. The Company expects the period benefited by each commission to be less than one year, and as a result, the Company expenses sales commissions as incurred. Sales commissions are reported on the condensed consolidated statements of income and comprehensive income as selling, general and administrative expenses.

Leases

Leases [Abstract]
Leases	8. The Company determines if an arrangement is or contains a lease at contract inception. The Company's leases consist of operating leases for office space and certain equipment through operating leases. The Company does not have any financing leases. For arrangements where the Company is the lessee, a right-of-use lease asset, representing the underlying asset during the lease term, and a right-of-use lease liability, representing the payment obligation arising from the lease, are recognized on the balance sheet at lease commencement based on the present value of the payment obligation. Right-of-use lease assets also include any initial direct costs incurred and any lease payments made at or before the lease commencement date, less lease incentives received. The Company's leases have a remaining contractual term of 1 year to 9 years, some of which include options to extend the lease term for up to five years and options to terminate. The options to extend certain lease terms or terminate certain leases are at the sole discretion of the Company. As the Company is not reasonably certain that it will exercise these options, none of the options to modify the lease terms are included in the Company’s right-of-use lease assets and right-of-use lease liabilities as of March 31, 2019. The Company’s weighted-average remaining lease term is 6.8 years as of March 31, 2019. Short-term operating leases with a contractual term of 12 months or less are not recorded on the balance sheet, but instead are included as selling, general and administrative expense on the condensed consolidated statements of income and comprehensive income and are considered rent expense. Certain of the Company's lease agreements include variable lease payments. Variable lease costs were $0.1 million for the three months ended March 31, 2019. Maturities of right-of-use lease liabilities by for the remaining five years and thereafter as of March 31, 2019 were as follows: (in millions) March 31, 2019 Remaining nine months of 2019 $ 2.8 2020 4.1 2021 3.4 2022 3.0 2023 3.0 Thereafter 7.9 Minimum lease payments $ 24.2 Less: Imputed interest (3.7 ) Present value of minimum lease payments $ 20.5 As of December 31, 2018, minimum lease payments under operating leases by period were as follows: (in millions) December 31, 2018 2019 $ 3.9 2020 4.0 2021 3.4 2022 3.0 2023 3.0 Thereafter 7.9 Total $ 25.2 Supplemental cash flow and other information related to leases was as follows: Three Months Ended March 31, (in millions) 2019 Cash paid for amounts included in the measurement of right-of-use lease liabilities Cash paid reported as operating activities on the condensed consolidated statements of cash flows $ 1.1 Right-of-use lease assets obtained in exchange for new right-of-use lease liabilities $ 0.2 The discount rate implicit within the Company’s leases is generally not determinable; therefore, the Company determined the discount rate based on its incremental borrowing rate using the portfolio approach. The Company’s weighted-average discount rate used to measure right-of-use lease liabilities was 5.2% as of March 31, 2019.

Earnings Per Share [Abstract]
Earnings Per Share	1 1 . Basic earnings per share is computed using the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed using the weighted-average number of common shares outstanding during the period, plus the dilutive effect of outstanding options, using the treasury stock method and the average market price of the Company's common stock during the applicable period. Certain shares related to some of the Company's outstanding stock options were excluded from the computation of diluted earnings per share because they were antidilutive in the periods presented, but could be dilutive in the future. The details of the computation of basic and diluted earnings per common share are as follows: Three Months Ended March 31, (dollars in millions, share data in thousands except earnings per share) 2019 2018 Net income $ 26.5 $ 38.1 Weighted average common shares outstanding 71,825 72,715 Basic earnings per share $ 0.37 $ 0.52 Net income $ 26.5 $ 38.1 Diluted effect of stock options 1,204 3,104 Diluted weighted average common shares outstanding 73,029 75,819 Diluted earnings per share $ 0.36 $ 0.50 Anti-dilutive shares excluded from diluted earnings per share calculation 3,605 1,118

Income Tax Disclosure [Abstract]
Income Taxes	1 2 . The Company has historically determined its interim income tax provision by applying the estimated effective income tax rate expected to be applicable for the full fiscal year to the income before income taxes for the period. In determining the full year estimate, the Company does not include the estimated impact of unusual and/or infrequent items, which may cause significant variations in the customary relationship between income tax expense and income before income taxes. Significant judgment is exercised in determining the income tax provision due to transactions, credits and calculations where the ultimate tax determination is uncertain. The Company’s U.S. corporate income federal tax rate was 21% as of March 31, 2019. For the three months ended March 31, 2019 and 2018, the Company recorded provisions for income taxes of $8.7 million and $12.5 million, respectively, which resulted in an effective tax rate of 24.7% for both periods. The differences between the statutory and effective tax rates are primarily attributable to the effects of state income taxes. Liabilities for unrecognized tax benefits and associated interest and penalties were $1.2 million and $1.1 million as of March 31, 2019 and December 31, 2018, respectively.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements include the operations of Emerald Expositions Events, Inc. (“the Company”) and its wholly-owned subsidiaries. These unaudited condensed consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC for Interim Reporting. All intercompany transactions, accounts and profits, if any, have been eliminated in the unaudited condensed consolidated financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These unaudited condensed consolidated financial statements do not include all disclosures required by GAAP, therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the more detailed audited consolidated financial statements for the year ended December 31, 2018. The December 31, 2018 condensed consolidated balance sheet was derived from the Company’s audited consolidated financial statements for the year ended December 31, 2018. The results for the three months ended March 31, 2019 are not necessarily indicative of results to be expected for a full year, any other interim periods or any future year or period.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). This update permitted entities to reclassify tax effects stranded in accumulated other comprehensive income as a result of tax reform from the Tax Cuts and Jobs Act. The adoption of ASU 2018-02 did not have an impact on the Company’s condensed consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”), to simplify the accounting for share-based payments made to nonemployees. Under ASU 2018-07, In July 2018, the FASB issued ASU 2018-09, Codification Improvements (“ASU 2018-09”). This standard did not prescribe any new accounting guidance, but instead made changes to a variety of topics to clarify, correct errors in, or make minor improvements to the In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASC 842”), which requires lessees to recognize most leases on their balance sheets as a right-of-use asset with a corresponding lease liability. The Company adopted ASC 842 on January 1, 2019 and elected to use the modified retrospective transition method prescribed under ASC 842 to not restate comparative periods in transition and use the effective date of ASC 842 as the date of initial adoption. Additionally, the Company applied the available practical expedient of keeping leases with an initial term of twelve months or less off of the balance sheet. As a result of the adoption of ASC 842 Leases Recently Issued Accounting Pronouncements There have been no other new accounting pronouncements that are expected to have a significant impact on the Company’s condensed consolidated financial statements or notes thereto.
Revenue Recognition and Deferred Revenue	The Company’s primary source of revenue is generated from the production of trade shows and conference events (collectively, “trade shows”), including booth space sales, registration fees and sponsorship fees. The Company recognizes revenue upon completion of each trade show. Trade show and conference events revenues represented approximately 95.2% and 96.1% of total revenues for the three months ended March 31, 2019 and 2018, respectively. Deferred revenues generally consist of booth space sales, registration fees and sponsorship fees that are invoiced prior to the trade show or other event. Current deferred revenues Performance Obligations For the Company’s trade shows and other events, sales are deferred and recognized when performance obligations under the terms of a contract with the Company’s customer are satisfied, which is typically at the completion of a show or event. Revenue is measured as the amount of consideration the Company expects to receive upon completion of performance obligations. For the Company’s other marketing services, sales are deferred and recognized when performance obligations under the terms of a contract with the Company’s customer are satisfied. This generally occurs in the period in which the publications are issued. Revenue is measured as the amount of consideration the Company expects to receive upon completion of performance obligations. The Company applied a practical expedient which allows the exclusion of disclosure Disaggregation of Revenue The Company’s primary sources of revenue are from trade shows, other events and other marketing services. The following table represents revenues disaggregated by type: Three Months Ended March 31, (in millions) 2019 2018 Trade shows $ 116.9 $ 123.7 Other events 13.8 13.0 Other marketing services 6.7 5.5 Total revenues $ 137.4 $ 142.2 Contract Balances Due to the nature of the Company’s revenue from contracts with customers, the Company does not have material contract assets that fall under the scope of ASC Topic 606. Contract liabilities generally consist of booth space sales, registration fees and sponsorship fees that are collected prior to the trade show or other event. The related revenue is recognized upon the completion of the applicable trade show or other event. Contract liabilities are reported on the condensed consolidated balance sheets as deferred revenues. The Company incurs sales commissions costs in connection with sales of booth space, registration fees and sponsorship fees at the Company’s trade shows and events and with sales of advertising for industry publications. The Company’s contracts with customers are generally short term, as sales generally begin up to one year prior to the date of the trade shows and other events. The Company expects the period benefited by each commission to be less than one year, and as a result, the Company expenses sales commissions as incurred. Sales commissions are reported on the condensed consolidated statements of income and comprehensive income as selling, general and administrative expenses.
