Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 — Summary of Significant Accounting Policies Consolidated Financial Statements The consolidated financial statements of the Company include the accounts of all majority-owned subsidiaries and controlled entities. All intercompany balances and transactions have been eliminated. The Company’s retail operations define a fiscal year (“Fiscal Year”) as the 52-week period or 53-week period ended on the Saturday nearest December 31st of each year, and define their fiscal quarters (“Fiscal Quarter”) as the four interim 13-week periods following the end of the previous Fiscal Year, except in the case of a 53-week Fiscal Year when the fourth Fiscal Quarter is extended to 14 weeks. The consolidated financial statements of the Company combine the Fiscal Year and Fiscal Quarters of the Company’s retail operations with the calendar year and calendar quarters of the Company’s wholesale operations, as the differences are not significant. Use of Estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Management periodically evaluates estimates used in the preparation of the consolidated financial statements for continued reasonableness. Appropriate adjustments, if any, to the estimates used are made prospectively based on such periodic evaluations. Cash Equivalents Highly liquid investments with a maturity of three months or less when purchased are considered to be cash equivalents. All credit card transactions that process in less than seven days are classified as cash and cash equivalents. Inventories Inventories are valued at the lower of cost and net realizable value. In assessing the ultimate realization of inventories, the Company makes judgments regarding, among other things, future demand and market conditions, current inventory levels and the impact of the possible discontinuation of product designs. The Company principally determines the cost of inventory using the weighted average method. The Company estimates retail inventory shrinkage for the period between physical inventory dates on a store-by-store basis. Inventory shrinkage estimates can be affected by changes in merchandise mix and changes in actual shortage trends. The shrinkage rate from the most recent physical inventory, in combination with historical experience, is the basis for estimating shrinkage. Allowance for Doubtful Accounts The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of the Company’s customers to make required payments. Judgment is required in assessing the ultimate realization of these receivables, including consideration of the Company’s history of receivable write-offs, the level of past due accounts and the economic status of the Company’s customers. In an effort to identify adverse trends relative to customer economic status, the Company assesses the financial health of the markets it operates in and performs periodic credit evaluations of its customers and ongoing reviews of account balances and aging of receivables. Amounts are considered past due when payment has not been received within the time frame of the credit terms extended. Write-offs are charged directly against the allowance for doubtful accounts and occur only after all collection efforts have been exhausted. At December 31, 2018 and 2017, the allowance for doubtful accounts was $2,933 and $2,971, respectively. Long-Lived and Intangible Assets (including Goodwill) Property, plant and equipment are stated at cost. Equipment under capital leases is stated at the present value of the minimum lease payments at the inception of the lease. Depreciation is calculated principally on the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or the estimated useful life of the asset. The Company reviews the recoverability of its finite long-lived assets, including finite-lived intangible assets, whenever facts and circumstances indicate that the carrying amount may not be fully recoverable. For purposes of recognizing and measuring impairment, the Company evaluates long-lived assets/asset groups, other than goodwill, based upon the lowest level of independent cash flows ascertainable to evaluate impairment. If an impairment indicator exists, we compare the undiscounted future cash flows of the asset/asset group to the carrying value of the asset/asset group. If the sum of the undiscounted future cash flows is less than the carrying value of the asset/asset group, the Company would recognize an impairment loss. The impairment related to long-lived assets is measured as the amount by which the carrying amount of the asset(s) exceeds the fair value of the asset(s). In the evaluation of the fair value and future benefits of finite long-lived assets attached to retail stores, the Company performs its cash flow analysis on a store-by-store basis. Various factors including future sales growth and profit margins are included in this analysis. Goodwill represents the excess of the purchase price of acquired entities over the estimated fair value of the net assets acquired. Goodwill and other intangibles with indefinite lives are not amortized, but are reviewed for impairment annually or more frequently if certain impairment indicators arise. The Company evaluates the goodwill associated with its acquisitions, and other intangibles with indefinite lives, for impairment as of the first day of its fourth quarter based on current and projected performance. For purposes of testing goodwill for impairment, reporting units are determined by identifying individual components within the Company’s organization which constitute a business for which discrete financial information is available and is reviewed by management. Components within a segment are aggregated to the extent that they have similar economic characteristics. Based on this evaluation, the Company has determined that its operating segments, wholesale and retail, represent reporting units for the purposes of its goodwill impairment test. If it is concluded that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company estimates the fair value of the reporting unit using a combination of a market approach and an income approach. If such carrying value exceeds the fair value an impairment loss will be recognized in an amount equal to such excess. The fair value of a reporting unit refers to the amount at which the unit as a whole could be sold in a current transaction between willing parties. Deferred Financing Costs Deferred financing costs are netted against amounts outstanding under the related debt instruments. They are amortized to interest expense over the terms of the instruments using the effective interest method. Deferred Rent and Rental Expenses The Company leases its retail stores under operating leases that generally have initial terms of ten years, with two five year renewal options. The Company’s leases may have early cancellation clauses, which permit the lease to be terminated if certain sales levels are not met in specific periods, and may provide for the payment of contingent rent based on a percentage of the store’s net sales. The Company’s lease agreements generally have defined escalating rent provisions, which are reported as a deferred rent liability and expensed on a straight-line basis over the term of the related lease, commencing with the date of possession. In addition, the Company may receive cash allowances from its landlords on certain properties, which are reported as deferred rent and amortized to rent expense over the term of the lease, also commencing with the date of possession. The Company’s deferred rent liability at December 31, 2018 and 2017 was $81,634 and $76,994, respectively. Equity Method Investments The Company has an investment in Convergram Mexico, S. De R.L. De C.V., a joint venture distributing metallic balloons, principally in Mexico and Latin America. The Company accounts for its 49.9% investment in the joint venture using the equity method of accounting. Additionally, the Company has an investment in PD Retail Group Limited, a joint venture operating party goods stores in the United Kingdom (“U.K.”). The Company accounts for its 50% investment using the equity method of accounting. Further, the Company has a 28% ownership interest in Punchbowl, Inc., a provider of digital greeting cards and digital invitations. The Company is also accounting for such investment under the equity method. The Company’s investments are included in other assets on the consolidated balance sheet and the results of the investees’ operations are included in other expense (income) in the consolidated statement of operations and comprehensive income (loss) (see Note 10). Insurance Accruals The Company maintains certain self-insured workers’ compensation and general liability insurance plans. The Company estimates the required liability for claims under such plans based upon various assumptions, which include, but are not limited to, historical loss experience, projected loss development factors, actual payroll and other data. The required liability is also subject to adjustment in the future based upon changes in claims experience, including changes in the number of incidents (frequency) and changes in the ultimate cost per incident (severity). Revenue Recognition Retail Revenue from retail store operations is recognized at the point of sale as control of the product is transferred to the customer at such time. Retail e-commerce sales are recognized when the consumer receives the product as control transfers upon delivery. Due to its extensive history operating as the largest party goods retailer in North America, the Company has sufficient history with which to estimate future retail sales returns and it uses the expected value method to estimate such activity. The transaction price for the majority of the Company’s retail sales is based on either: 1) the item’s stated price or 2) the stated price adjusted for the impact of a coupon which can only be applied to such transaction. To the extent that the Company charges customers for freight costs on e-commerce sales, the Company records such amounts in revenue. The Company excludes all sales taxes and value-added taxes from revenue. Under the terms of its agreements with its franchisees, the Company provides both: 1) brand value (via significant advertising spend) and 2) support with respect to planograms, in exchange for a royalty fee that ranges from 4% to 6% of the franchisees’ sales. The Company records the royalty fees at the time that the franchisees’ sales are recorded. Additionally, although the Company anticipates that future franchise store openings will be limited, when a franchisee opens a new store, the Company receives and records a one-time fee which is earned by the Company for its assistance with site selection and development of the new location. Both the sales-based royalty fee and the one-time fee are recorded in royalties and franchise fees in the Company’s consolidated statement of operations and comprehensive income. Wholesale For most of the Company’s wholesale sales, control transfers upon the Company’s shipment of the product. Wholesale sales returns are not significant as the Company generally only accepts the return of goods that were shipped to the customer in error or that were damaged when received by the customer. Additionally, due to its extensive history operating as a leading party goods wholesaler, the Company has sufficient history with which to estimate future sales returns. In most cases, the determination of the transaction price is fixed based on the contract and/or purchase order. To the extent that the Company charges customers for freight costs, the Company records such amounts in revenue. The Company excludes all sales taxes and value-added taxes from revenue. The majority of the sales for the Company’s wholesale business are due within 30 to 120 days from the transfer of control of the product and substantially all of the sales are collected within a year from such transfer. For all transactions for which the Company expects to collect the transaction price within a year from the transfer of control, the Company does not adjust the consideration for the effects of a significant financing component. Cost of Sales Cost of sales at wholesale reflects the production costs (i.e., raw materials, labor and overhead) of manufactured goods and the direct cost of purchased goods, inventory shrinkage, inventory adjustments, inbound freight to the Company’s manufacturing and distribution facilities, distribution costs and outbound freight to transfer goods to the Company’s wholesale customers. At retail, cost of sales reflects the direct costs of goods purchased from third parties and the production costs/purchase costs of goods acquired from the Company’s wholesale operations. Retail cost of sales also includes inventory shrinkage, inventory adjustments, inbound freight, occupancy costs related to store operations (such as rent, utilities and common area maintenance), depreciation on assets and all logistics costs (i.e., handling and distribution costs) associated with the Company’s e-commerce business. Retail Operating Expenses Retail operating expenses include costs associated with the operation of the Company’s retail stores (with the exception of occupancy costs, which are included in cost of sales). Retail operating expenses principally consist of employee compensation and benefits, advertising, supplies expense and credit card fees. Shipping and Handling Outbound shipping costs billed to customers are included in net sales. The costs of shipping and handling incurred by the Company are included in cost of sales. Product Royalty Agreements The Company enters into product royalty agreements that allow the Company to use licensed designs on certain of its products. These contracts require the Company to pay royalties, generally based on the sales of such product, and may require guaranteed minimum royalties, a portion of which may be paid in advance. The Company matches royalty expense with revenue by recording royalties at the time of sale, at the greater of the contractual rate or an effective rate calculated based on the guaranteed minimum royalty and the Company’s estimate of sales during the contract period. If a portion of the guaranteed minimum royalty is determined to be unrecoverable, the unrecoverable portion is charged to expense at that time. Guaranteed minimum royalties paid in advance are recorded in the consolidated balance sheets in either prepaid expenses and other current assets or other assets, depending on the nature of the royalties. Catalog Costs The Company expenses costs associated with the production of catalogs when incurred. Advertising Advertising costs are expensed as incurred. Retail advertising expenses for the years ended December 31, 2018, December 31, 2017, and December 31, 2016 were $68,756, $61,187, and $63,528, respectively. Variable Interest Entities When determining whether a legal entity should be consolidated, the Company first determines whether it has a variable interest in the legal entity. If a variable interest exists, the Company determines whether the legal entity is a variable interest entity due to either: 1) a lack of sufficient equity to finance its activities, 2) the equity holders lacking the characteristics of a controlling financial interest, or 3) the legal entity being structured with non-substantive voting rights. If the Company concludes that the legal entity is a variable interest entity, the Company next determines whether it is the primary beneficiary due to it possessing both: 1) the power to direct the activities of a variable interest entity that most significantly impact the variable interest entity’s economic performance, and 2) the obligation to absorb losses of the variable interest entity that potentially could be significant to the variable interest entity or the right to receive benefits from the variable interest entity which could be significant to the variable interest entity. If the Company concludes that it is the primary beneficiary, it consolidates the legal entity. During 2017, the Company and Ampology, a subsidiary of Trivergence, reached an agreement to form a new legal entity, Kazzam, LLC (“Kazzam”), for the purpose of designing, developing and launching an online exchange platform for party-related services. Although the Company currently only owns 26% of Kazzam’s equity, the Company has concluded that: a) Kazzam is a variable interest entity as it has insufficient equity at risk, and b) the Company is its primary beneficiary. Therefore, the Company has consolidated Kazzam into the Company’s financial statements. As part of Ampology’s compensation for designing, developing and launching the exchange platform, Ampology received an ownership interest in Kazzam. The interest has been recorded as redeemable securities in the mezzanine of the Company’s consolidated balance sheet as, in the future, Ampology has the right to cause the Company to purchase the interest. On a recurring basis, the mezzanine liability is adjusted to the greater of: a) the interest’s carrying amount under Accounting Standards Codification (“ASC”) Topic 810, “Consolidation”, or b) the fair value of the interest. Art and Development Costs Art and development costs are primarily internal costs that are not easily associated with specific designs, some of which may not reach commercial production. Accordingly, the Company expenses these costs as incurred. Derivative Financial Instruments ASC Topic 815, “Accounting for Derivative Instruments and Hedging Activities”, requires that all derivative financial instruments be recognized on the balance sheet at fair value and establishes criteria for both the designation and effectiveness of hedging activities. The Company uses derivatives in the management of interest rate and foreign currency exposure. ASC Topic 815 requires the Company to formally document the assets, liabilities or other transactions the Company designates as hedged items, the risk being hedged and the relationship between the hedged items and the hedging instruments. The Company must measure the effectiveness of the hedging relationship at the inception of the hedge and on an on-going basis. If derivative financial instruments qualify as fair value hedges, the gain or loss on the instrument and the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in net income during the period of the change in fair values. For derivative financial instruments that qualify as cash flow hedges ( i.e i.e Income Taxes Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities (and operating loss and tax credit carryforwards) applying enacted statutory tax rates in effect for the years in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance when, in the judgment of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Stock-Based Compensation Accounting for stock-based compensation requires measurement of compensation cost for all stock-based awards at fair value on the date of grant and recognition of compensation expense over the service period for awards expected to vest. Accumulated Other Comprehensive Loss Accumulated other comprehensive loss consists of the Company’s foreign currency adjustments and the impact of interest rate swap and foreign exchange contracts that qualify as hedges (see Notes 18 and 19). Foreign Currency Transactions and Translation The functional currencies of the Company’s foreign operations are the local currencies in which they operate. Foreign currency exchange gains or losses resulting from receivables or payables in currencies other than the functional currencies generally are recognized in the Company’s statement of operations and comprehensive income (loss). The balance sheets of foreign subsidiaries are translated into U.S. dollars at the exchange rates in effect on the balance sheet date. The results of operations of foreign subsidiaries are translated into U.S. dollars at the average exchange rates effective for the periods presented. The differences from historical exchange rates are recorded as comprehensive income (loss) and are included as a component of accumulated other comprehensive loss. Earnings Per Share Basic earnings per share are computed by dividing net income attributable to common shareholders of Party City Holdco Inc. by the weighted average number of common shares outstanding for the period. Diluted earnings per share are calculated based on the weighted average number of outstanding common shares plus the dilutive effect of stock options and warrants, as if they were exercised, and restricted stock units, as if they vested. A reconciliation between basic and diluted income per share is as follows: Year Ended Year Ended Year Ended 2016 Net income attributable to common shareholders of Party City Holdco Inc.: $ 123,259 $ 215,340 $ 117,477 Weighted average shares — Basic: 96,133,144 118,589,421 119,381,842 Effect of dilutive restricted stock units: 9,661 0 0 Effect of dilutive stock options: 1,128,245 1,304,600 987,830 Weighted average shares — Diluted: 97,271,050 119,894,021 120,369,672 Net income per share attributable to common shareholders of Party City Holdco Inc. — Basic: $ 1.28 $ 1.81 $ 0.98 Net income per share attributable to common shareholders of Party City Holdco Inc. — Diluted: $ 1.27 $ 1.79 $ 0.98 During the years ended December 31, 2018, December 31, 2017, and December 31, 2016, 2,394,868 stock options, 2,392,150 stock options and 2,371,876 stock options, respectively, were excluded from the calculations of net income per share attributable to common shareholders of Party City Holdco Inc. – diluted as they were anti-dilutive. Additionally, during the years ended December 31, 2018, December 31, 2017, and December 31, 2016, 596,000 warrants, 596,000 warrants and 0 warrants, respectively, were excluded from the calculations of net income per share attributable to common shareholders of Party City Holdco Inc. – diluted as they were anti-dilutive. Further, during the years ended December 31, 2018, December 31, 2017, and December 31, 2016, 141,400 restricted stock units, 0 restricted stock units and 0 restricted stock units, respectively, were excluded from the calculations of net income per share attributable to common shareholders of Party City Holdco Inc. – diluted as they were anti-dilutive. Recently Issued Accounting Pronouncements In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-07, “Compensation — Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting”. The ASU simplifies the accounting for non-employee share-based payments. The update is effective for the Company during the first quarter of 2019. Although the Company continues to evaluate this pronouncement, it does not believe that it will have a material impact on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities”. The pronouncement amends the existing hedge accounting model in order to enable entities to better portray the economics of their risk management activities in their financial statements. The update is effective for the Company during the first quarter of 2019. Although the Company continues to evaluate this pronouncement, it does not believe that it will have a material impact on the Company’s consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows: Restricted Cash”. The pronouncement requires companies to show changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. The Company adopted the pronouncement, which requires retrospective application, during the first quarter of 2018. The impact of such adoption was immaterial to the Company’s consolidated financial statements. See Note 22 for further discussion. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments”. The pronouncement clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The Company adopted the pronouncement during the first quarter of 2018 and such adoption did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases”. The ASU requires that companies recognize assets and liabilities for the rights and obligations created by companies’ leases. The update is effective for the Company during the first quarter of 2019. The Company’s current lease portfolio is primarily comprised of store leases, manufacturing and distribution facility leases and office leases. Most of the Company’s leases are operating leases. The Company’s finance leases are not material to its consolidated financial statements. Upon adoption of this standard, the Company will recognize a right of use asset and liability related to substantially all of its operating lease arrangements with terms of greater than twelve months. The Company established a cross-functional team to implement the pronouncement and the team has finalized the implementation of a new software solution and its assessment of the practical expedients and policy elections offered by the standard. Due to the nature of the Company’s business, it is often executing new leases and amending existing leases. Currently, the Company estimates that its right of use asset for its operating leases will be in the range of $740,000 to $820,000. Additionally, the Company currently estimates that its liability for its operating leases will be in the range of $820,000 to $900,000. The adoption of the pronouncement will not have a material impact on the Company’s consolidated statement of operations and comprehensive income and it will not impact the Company’s compliance with its debt covenants. The FASB has provided companies with a transition option under which they can opt to continue to apply legacy guidance in comparative periods and recognize a cumulative effect adjustment to January 1, 2019 retained earnings (if applicable). The Company has elected the option. The cumulative effect adjustment will not have a material impact on the Company’s consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments — Overall: Recognition and Measurement of Financial Assets and Financial Liabilities”. The update impacts the accounting for equity investments and the recognition of changes in fair value of financial liabilities when the fair value option is elected. The Company adopted the pronouncement during the first quarter of 2018 and such adoption had no impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. The pronouncement contains a five-step model which replaces most existing revenue recognition guidance. The new standard became effective for the Company on January 1, 2018. The Company adopted the pronouncement using the modified retrospective approach. Therefore, on January 1, 2018, the Company adjusted its accounting for certain discounts which are related to the timing of payments by customers of its wholesale business and the Company recorded a cumulative-effect adjustment which reduced retained earnings by $46. Additionally, as of such date, the Company modified its accounting for certain metallic balloon sales of its wholesale segment and started to defer the recognition of revenue on such sales, and the related costs, until the balloons have been filled with helium. As a result, the Company recorded a cumulative-effect adjustment which increased retained earnings by $8. Finally, as of such date, the Company adjusted its accounting for certain discounts on wholesale sales of seasonal product and the Company recorded a cumulative-effect adjustment which reduced retained earnings by $40. See Note 20 for further discussion of the adoption of the pronouncement and the Company’s revenue recognition policy.

Business Combinations [Abstract]
Acquisitions	Note 5 — Acquisitions During March 2018, the Company acquired 11 franchise stores, which are located in Maryland, for total consideration (including non-cash consideration) of approximately $17,000. The following summarizes the fair values of the major classes of assets acquired and liabilities assumed: inventories of $3,500, property, plant and equipment of $200, a reacquired right intangible asset in the amount of $4,000, and an asset in the amount of $100 due to leases that are favorable when compared to market rates. The allocation of the purchase price for the business combination, which has been finalized with the exception of the allocation of value to the stores’ income tax accounts, was based on the Company’s estimate of the fair value of the assets acquired and liabilities assumed. Goodwill, which is tax-deductible, arose due to numerous factors, including the wholesale profit generated via the sale of product from the Company’s wholesale operations through the 11 stores. Goodwill also arose due to: the value to the Company of customers knowing that there are party stores in the locations (when the Company opens a new store, sales are initially lower than those of mature stores and increase over time), the Company’s ability to run the stores more efficiently than the franchisee based on the Company’s experience with its approximately 800 corporate-owned stores and the assembled workforce at the 11 stores. Also, during July 2018, the Company acquired an additional 16 franchise stores, which are located in Pennsylvania, for total consideration (including non-cash consideration) of approximately $20,500. The following summarizes the fair values of the major classes of assets acquired and liabilities assumed: inventories of $4,200, property, plant and equipment of $500, a reacquired right intangible asset in the amount of $3,400, and an asset in the amount of $500 due to leases that are favorable when compared to market rates. The allocation of the purchase price for the business combination, which has been finalized with the exception of the allocation of value to the stores’ income tax accounts, was based on the Company’s estimate of the fair value of the assets acquired and liabilities assumed. Goodwill, which is tax-deductible, arose due to numerous factors, including the wholesale profit generated via the sale of product from the Company’s wholesale operations through the 16 stores. Goodwill also arose due to: the value to the Company of customers knowing that there are party stores in the locations (when the Company opens a new store, sales are initially lower than those of mature stores and increase over time), the Company’s ability to run the stores more efficiently than the franchisee based on the Company’s experience with its approximately 800 corporate-owned stores and the assembled workforce at the 16 stores. Additionally, during September 2018, the Company acquired 21 franchise stores, which are located in Minnesota, North Dakota and Texas, for total consideration (including non-cash consideration) of approximately $26,300. The following summarizes the fair values of the major classes of assets acquired and liabilities assumed: inventories of $7,500, property, plant and equipment of $500, a reacquired right intangible asset in the amount of $7,300, and an asset in the amount of $200 due to leases that are favorable when compared to market rates. The allocation of the purchase price for the business combination, which has been finalized with the exception of the allocation of value to the stores’ income tax accounts, was based on the Company’s estimate of the fair value of the assets acquired and liabilities assumed. Goodwill, which is tax-deductible, arose due to numerous factors, including the wholesale profit generated via the sale of product from the Company’s wholesale operations through the 21 stores. Goodwill also arose due to: the value to the Company of customers knowing that there are party stores in the locations (when the Company opens a new store, sales are initially lower than those of mature stores and increase over time), the Company’s ability to run the stores more efficiently than the franchisee based on the Company’s experience with its approximately 800 corporate-owned stores and the assembled workforce at the 21 stores. Also, during 2018, the Company entered into an agreement to acquire 11 independent stores, which are located in Texas. The Company will take control of the stores one at a time over a period of approximately two years. During 2018, the Company took control of eight of the 11 stores, for total business combination consideration of approximately $4,400. Although the Company is finalizing the allocation of the purchase price for the eight stores, the majority of the value will be ascribed to goodwill. Goodwill, which is tax-deductible, arose due to numerous factors, including the wholesale profit generated via the sale of product from the Company’s wholesale operations through the stores. Due to the fact that the stores were independent stores and, therefore, possessed a relatively small percentage of inventory that came from the Company’s wholesale operations, going forward the Company will significantly increase such percentage. Additionally, goodwill arose due to: the value to the Company of customers knowing that there are party stores in the locations, the Company’s ability to run the stores more efficiently than the current operator based on the Company’s experience with its approximately 800 corporate-owned stores and the assembled workforce at the eight stores. Pro forma financial information has not been presented because the impact of the acquisitions individually, and in the aggregate, is not material to the Company’s consolidated financial results. Goodwill Changes by Reporting Segment For the years ended December 31, 2018 and December 31, 2017 goodwill changes were as follows: Year Ended Year Ended Wholesale segment: Beginning balance $ 513,946 $ 491,859 Granmark acquisition (1,115 ) 13,241 Print Appeal acquisition 277 3,133 Other acquisitions 132 1,348 Foreign currency impact (2,750 ) 4,365 Ending balance 510,490 513,946 Retail segment: Beginning balance 1,105,307 1,080,709 Store acquisitions 42,801 23,025 Foreign currency impact (1,648 ) 1,573 Ending balance 1,146,460 1,105,307 Total ending balance, both segments $ 1,656,950 $ 1,619,253

Debt Disclosure [Abstract]
Loans and Notes Payable	Note 7 — Loans and Notes Payable ABL Facility The Company has a $540,000 asset-based revolving credit facility (with a seasonal increase to $640,000 during a certain period of each calendar year) (“ABL Facility”) which matures during August 2023 (subject to a springing maturity at an earlier date if the maturity date of certain of the Company’s other debt has not been extended or refinanced). It provides for (a) revolving loans, subject to a borrowing base described below, and (b) letters of credit, in an aggregate face amount at any time outstanding not to exceed $50,000. Under the ABL Facility, the borrowing base at any time equals (a) a percentage of eligible trade receivables, plus (b) a percentage of eligible inventory, plus (c) a percentage of eligible credit card receivables, less (d) certain reserves. The ABL Facility generally provides for two pricing options: (i) an alternate base interest rate (“ABR”) equal to the greater of (a) the prime rate, (b) the federal funds rate plus 0.5% or (c) the LIBOR rate plus 1%, in each case, on the date of such borrowing or (ii) a LIBOR based interest rate, in each case plus an applicable margin. The applicable margin ranges from 0.25% to 0.50% with respect to ABR borrowings and from 1.25% to 1.50% with respect to LIBOR borrowings. In addition to paying interest on outstanding principal, the Company is required to pay a commitment fee of 0.25% per annum in respect of unutilized commitments. The Company must also pay customary letter of credit fees. All obligations under the ABL Facility are jointly and severally guaranteed by PC Intermediate, PCHI and each existing and future domestic subsidiary of PCHI. PCHI and each guarantor has secured its obligations, subject to certain exceptions and limitations, including obligations under its guaranty, as applicable, by a first-priority lien on its accounts receivable, inventory, cash and certain related assets and a second-priority lien on substantially all of its other assets. The facility contains negative covenants that, among other things and subject to certain exceptions, restrict the ability of PCHI to: • incur additional indebtedness; • pay dividends on capital stock or redeem, repurchase or retire capital stock; • make certain investments, loans, advances and acquisitions; • engage in transactions with affiliates; • create liens; and • transfer or sell certain assets. In addition, PCHI must comply with a fixed charge coverage ratio if excess availability under the ABL Facility on any day is less than the greater of: (a) 10% of the lesser of the aggregate commitments and the then borrowing base under the ABL Facility and (b) $40,000. The fixed charge coverage ratio is the ratio of (i) Adjusted EBITDA (as defined in the facility) minus maintenance-related capital expenditures (as defined in the facility) to (ii) fixed charges (as defined in the facility). The ABL Facility also contains certain customary affirmative covenants and events of default. In connection with entering into and amending the ABL Facility, the Company incurred and capitalized third-party costs. All capitalized costs are being amortized over the life of the ABL Facility and are included in loans and notes payable in the Company’s consolidated balance sheet. The balance of related unamortized financing costs at December 31, 2018 was $2,459. Borrowings under the ABL Facility totaled $303,500 at December 31, 2018. The weighted average interest rate for such borrowings was 4.46% at December 31, 2018. Outstanding standby letters of credit totaled $26,178 at December 31, 2018 and, after considering borrowing base restrictions, at December 31, 2018 PCHI had $210,322 of available borrowing capacity under the terms of the facility. Other Credit Agreements The Company’s subsidiaries have also entered into several foreign asset-based and overdraft credit facilities that provide the Company with additional borrowing capacity. At December 31, 2018 and 2017, there were $1,710 and $2,251 borrowings outstanding under the foreign facilities, respectively. The facilities contain customary affirmative and negative covenants.

Long-Term Obligations	Note 8 — Long-Term Obligations Long-term obligations consisted of the following: December 31, 2018 2017 Senior secured term loan facility (“Term Loan Credit Agreement”) $ 791,135 $ 1,196,505 6.125% Senior Notes — due 2023 346,191 345,368 6.625% Senior Notes — due 2026 494,138 0 Capital lease obligations 3,815 3,276 Total long-term obligations 1,635,279 1,545,149 Less: current portion (13,316 ) (13,059 ) Long-term obligations, excluding current portion $ 1,621,963 $ 1,532,090 Term Loan Credit Agreement Amendment During February 2018, the Company amended its Term Loan Credit Agreement. At the time of the amendment, all outstanding term loans were replaced with new term loans for the same principal amount. The applicable margin for ABR borrowings was lowered from 2.00% to 1.75% and the applicable margin for LIBOR borrowings was lowered from 3.00% to 2.75%. Additionally, based on the terms of the amendment, the ABR and LIBOR margins will drop to 1.50% and 2.50%, respectively, if PCHI’s Senior Secured Leverage Ratio, as defined by the agreement, falls below 3.2 to 1.0. As the Term Loan Credit Agreement is a loan syndication, the Company assessed, on a creditor-by-creditor basis, whether the refinancing should be accounted for as an extinguishment or a modification for each creditor and, during 2018, the Company wrote-off $186 of existing deferred financing costs, a $102 capitalized original issue discount and $58 of capitalized call premium. The write-offs were recorded in other expense in the Company’s consolidated statement of operations and comprehensive income. The remaining deferred financing costs, original issue discount and capitalized call premium will continue to be amortized over the life of the Term Loan Credit Agreement, using the effective interest method. Additionally, in conjunction with the amendment, the Company incurred $856 of banker and legal fees, $800 of which were recorded in other expense during 2018. The rest of the costs are being amortized over the term of the debt. August 2018 Refinancing During August 2018, the Company executed a refinancing of its debt portfolio and issued $500,000 of new senior notes at an interest rate of 6.625%. The notes will mature in August 2026. The Company used the proceeds from the notes to: (i) reduce the outstanding balance under its existing ABL Facility, which is included in loans and notes payable on the Company’s condensed consolidated balance sheet, by $90,000 and (ii) voluntarily prepay $400,000 of the outstanding principal under its existing Term Loan Credit Agreement. Additionally, as part of the refinancing, the Company extended the maturity of the ABL Facility to August 2023 (subject to a springing maturity at an earlier date if the maturity date of certain of the Company’s other debt has not been extended or refinanced). As the partial prepayment of the Term Loan Credit Agreement was in accordance with the terms of such agreement, at the time of such prepayment the Company wrote-off a pro-rata portion of the existing capitalized deferred financing costs and original issuance discounts, $1,824, for investors who did not participate in the new notes. Such amount was recorded in other expense in the Company’s consolidated statement of operations and comprehensive income. To the extent that investors in the Term Loan Credit Agreement participated in the new notes, the Company assessed whether the refinancing should be accounted for as an extinguishment on a creditor-by-creditor basis and wrote-off $968 of existing deferred financing costs and original issuance discounts. Such amount was recorded in other expense in the Company’s consolidated statement of operations and comprehensive income. Additionally, in conjunction with the issuance of the notes, the Company incurred third-party fees (principally banker fees). To the extent that such fees related to investors for whom their original debt was not extinguished, the Company expensed the portion of such fees, $2,270 in aggregate, that related to such investors. Such amount was recorded in other expense in the Company’s consolidated statement of operations and comprehensive income. The remainder of the third-party fees, $6,230, have been capitalized and will be amortized over the remaining life of the debt using the effective interest method. Further, in conjunction with the extension of the ABL Facility, the Company compared the borrowing capacities of the pre-amendment facility and the post-amendment facility, on a creditor-by-creditor basis, and concluded that $29 of existing deferred financing costs should be written-off. Such amount was recorded in other expense in the Company’s consolidated statement of operations and comprehensive income. The remaining capitalized costs, and $986 of new third-party costs incurred in conjunction with the extension, are being amortized over the revised term of the ABL Facility. Term Loan Credit Agreement The Term Loan Credit Agreement provides for two pricing options for outstanding loans: (i) an ABR for any day, a rate per annum equal to the greater of (a) the prime rate in effect on such day, (b) the federal funds effective rate in effect on such day plus 0.5%, (c) the adjusted LIBOR rate plus 1% and (d) 1.75% or (ii) the LIBOR rate, with a LIBOR floor of 0.75%, in each case plus an applicable margin. The applicable margin for ABR borrowings ranges from 1.50% to 1.75% and the applicable margin for LIBOR borrowings ranges from 2.50% to 2.75%, depending on PCHI’s Senior Secured Leverage Ratio (as defined by the agreement). The term loans under the Term Loan Credit Agreement mature on August 19, 2022. The Company is required to repay installments on the loans in quarterly principal amounts of 0.25%, with the remaining amount payable on the maturity date. Additionally, outstanding term loans are subject to mandatory prepayment, subject to certain exceptions, with (i) 100% of net proceeds above a threshold amount of certain asset sales/insurance proceeds, subject to reinvestment rights and certain other exceptions, (ii) 100% of the net cash proceeds of any incurrence of debt other than debt permitted under the Term Loan Credit Agreement, and (iii) 50% of Excess Cash Flow, as defined in the agreement, if any (reduced to 25% if PCHI’s first lien leverage ratio (as defined in the agreement) is less than 3.50 to 1.00, but greater than 2.50 to 1.00, and 0% if PCHI’s first lien leverage ratio is less than 2.50 to 1.00). The term loans may be voluntarily prepaid at any time without premium or penalty, other than customary breakage costs with respect to loans based on the LIBOR rate. All obligations under the agreement are jointly and severally guaranteed by PC Intermediate, PCHI and each existing and future domestic subsidiary of PCHI. PCHI and each guarantor has secured its obligations, subject to certain exceptions and limitations, by a first-priority lien on substantially all of its assets (other than accounts receivable, inventory, cash and certain related assets), including a pledge of all of the capital stock held by PC Intermediate, PCHI and each guarantor, and a second-priority lien on its accounts receivable, inventory, cash and certain related assets. The Term Loan Credit Agreement contains certain customary affirmative covenants and events of default. Additionally, it contains negative covenants which, among other things and subject to certain exceptions, restrict the ability of PCHI to: • incur additional indebtedness; • pay dividends on capital stock or redeem, repurchase or retire capital stock; • make certain investments, loans, advances and acquisitions; • engage in transactions with affiliates; • create liens; and • transfer or sell certain assets. At December 31, 2018, the principal amount of term loans outstanding under the Term Loan Credit Agreement was $799,917. Such amount is recorded net of original issue discounts, capitalized call premiums and deferred financing costs on the Company’s consolidated balance sheet. At December 31, 2018, original issue discounts, capitalized call premiums and deferred financing costs totaled $8,782. At December 31, 2018, all outstanding borrowings were based on LIBOR and were at a weighted average interest rate of 5.03%. 6.125% Senior Notes — Due 2023 (“6.125% Senior Notes”) The 6.125% Senior Notes mature on August 15, 2023. Interest on the notes is payable semi-annually in arrears on February 15 and August 15 of each year. The notes are guaranteed, jointly and severally, on a senior basis by each of PCHI’s existing and future wholly-owned domestic subsidiaries. The notes and the guarantees are general unsecured senior obligations and are effectively subordinated to all other secured debt to the extent of the assets securing such secured debt. The indenture governing the notes contains certain covenants limiting, among other things and subject to certain exceptions, PCHI’s ability to: • incur additional indebtedness or issue certain disqualified stock and preferred stock; • pay dividends or distributions, redeem or repurchase equity; • prepay subordinated debt or make certain investments; • engage in transactions with affiliates; • consolidate, merge or transfer all or substantially all of PCHI’s assets; • create liens; and • transfer or sell certain assets. The indenture governing the notes also contains certain customary affirmative covenants and events of default. The Company may redeem the notes, in whole or in part, at the following (expressed as a percentage of the principal amount to be redeemed): Twelve-month period beginning on August 15, Percentage 2018 103.063 % 2019 101.531 % 2020 and thereafter 100.000 % Also, if the Company experiences certain types of change in control, as defined, the Company may be required to offer to repurchase the Senior Notes at 101% of their principal amount. In connection with issuing the notes, the Company incurred and capitalized third-party costs. Capitalized costs are being amortized over the life of the debt and are included in long-term obligations, excluding current portion, in the Company’s consolidated balance sheet. At December 31, 2018, $3,809 of costs were capitalized. 6.625% Senior Notes — Due 2026 (“6.625% Senior Notes”) The 6.625% Senior Notes mature on August 1, 2026. Interest on the notes is payable semi-annually in arrears on February 1st and August 1st of each year. The notes are guaranteed, jointly and severally, on a senior basis by each of PCHI’s existing and future wholly-owned domestic subsidiaries. The notes and the guarantees are general unsecured senior obligations and are effectively subordinated to all other secured debt to the extent of the assets securing such secured debt. The indenture governing the notes contains certain covenants limiting, among other things and subject to certain exceptions, PCHI’s ability to: • incur additional indebtedness or issue certain disqualified stock and preferred stock; • pay dividends or distributions, redeem or repurchase equity; • prepay subordinated debt or make certain investments; • engage in transactions with affiliates; • consolidate, merge or transfer all or substantially all of PCHI’s assets; • create liens; and • transfer or sell certain assets. The indenture governing the notes also contains certain customary affirmative covenants and events of default. On or after August 1, 2021, the Company may redeem the notes, in whole or in part, at the following (expressed as a percentage of the principal amount to be redeemed): Twelve-month period beginning on August 1, Percentage 2021 103.313 % 2022 101.656 % 2023 and thereafter 100.000 % In addition, the Company may redeem up to 40% of the aggregate principal amount outstanding on or before August 1, 2021 with the cash proceeds from certain equity offerings at a redemption price of 106.625% of the principal amount. The Company may also redeem some or all of the notes before August 1, 2021 at a redemption price of 100% of the principal amount plus a premium that is defined in the indenture. Also, if the Company experiences certain types of change in control, as defined, the Company may be required to offer to repurchase the notes at 101% of their principal amount. In connection with issuing the notes, the Company incurred and capitalized third-party costs. Capitalized costs are being amortized over the life of the debt and are included in long-term obligations, excluding current portion, in the Company’s consolidated balance sheet. At December 31, 2018, $5,862 of costs were capitalized. Other Indebtedness Additionally, the Company has entered into various capital leases for machinery and equipment. At December 31, 2018 and December 31, 2017 the balances of such leases were $3,815 and $3,276, respectively. Subject to certain exceptions, PCHI may not make certain payments, including the payment of dividends to its shareholders (“restricted payments”), unless certain conditions are met under the terms of the indentures governing the senior notes, the ABL Facility and the Term Loan Credit Agreement. As of December 31, 2018, the most restrictive of these conditions existed in the Term Loan Credit Agreement, which limits restricted payments based on PCHI’s consolidated net income and leverage ratios. As of December 31, 2018, PCHI had $129,022 of capacity under the debt instrument to make restricted payments. PCHI’s parent companies, PC Intermediate, PC Nextco and Party City Holdco, have no assets or operations other than their investments in their subsidiaries and income from those subsidiaries. At December 31, 2018, maturities of long-term obligations consisted of the following: Long-Term Debt Capital Lease Totals 2019 $ 12,266 $ 1,050 $ 13,316 2020 12,266 940 13,206 2021 12,266 1,154 13,420 2022 763,119 651 763,770 2023 350,000 20 350,020 Thereafter 500,000 0 500,000 Long-term obligations $ 1,649,917 $ 3,815 $ 1,653,732

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Incentive Plans	Note 12 — Equity Incentive Plans Party City Holdco has adopted the Amended and Restated 2012 Omnibus Equity Incentive Plan (the “2012 Plan”) under which it can grant incentive awards in the form of stock appreciation rights, restricted stock and common stock options to certain directors, officers, employees and consultants of Party City Holdco and its affiliates. A committee of Party City Holdco’s Board of Directors, or the Board itself in the absence of a committee, is authorized to make grants and various other decisions under the 2012 Plan. The maximum number of shares reserved under the 2012 Plan is 15,316,000 shares. Time-based options Party City Holdco grants time-based options to key eligible employees and outside directors. In conjunction with the options, the Company recorded compensation expense of $1,744, $5,309, and $3,853 during the years ended December 31, 2018, December 31, 2017, and December 31, 2016, respectively. The fair value of time-based options granted during the year ended December 31, 2018 was estimated on the grant date using a Black-Scholes option valuation model based on the assumptions in the following table: Expected dividend rate 0% Risk-free interest rate 2.66% to 2.97% Volatility 26.94% to 28.46% Expected option term 5 years — 6.5 years As Party City Holdco’s stock only recently started trading publicly, the Company determined volatility based on the average historical volatility of guideline companies. Additionally, as there is not sufficient historical exercise data to provide a reasonable basis for determining the expected terms of the options, the Company estimated such expected terms based on the assumption that options will be exercised at the mid-point of the vesting of the options and the completion of the contractual lives of such options. The Company has based its estimated forfeiture rate on historical forfeitures for time-based options as the number of options given to each of the various levels of management is principally consistent with historical grants and forfeitures are expected to be materially consistent with past experience. The Company’s time-based options principally vest 20% on each anniversary date. The Company records compensation expense for such options on a straight-line basis. As of December 31, 2018, there was $3,731 of unrecognized compensation cost, which will be recognized over a weighted-average period of approximately 30 months. Performance-based options During 2013, Party City Holdco granted performance-based stock options to key employees and independent directors. For performance-based options, vesting is contingent upon Thomas H. Lee Partners, L.P. (“THL”) achieving specified investment returns when it sells its ownership stake in Party City Holdco. Since the sale of THL’s shares cannot be assessed as probable before it occurs, no compensation expense has been recorded for the performance-based options that have been granted. As of December 31, 2018, 3,035,200 performance-based options were outstanding. Based on a Monte Carlo simulation and the following assumptions, the options have an average grant date fair value of $3.09 per option: Expected dividend rate 0% Risk-free interest rate 1.86% Volatility 52.00% Expected option term 5 years As Party City Holdco’s stock was not publicly traded when the performance-based options were granted, the Company determined volatility based on the average historical volatility of guideline companies. The following table summarizes the changes in outstanding stock options for the years ended December 31, 2016, December 31, 2017, and December 31, 2018. Options Average Average Fair Value of Time-Based Grant Date Aggregate Weighted Average Remaining Outstanding at December 31, 2015 8,517,645 Granted 484,950 $ 15.78 $ 4.68 Exercised (257,520 ) 5.33 Forfeited (283,249 ) 10.05 Outstanding at December 31, 2016 8,461,826 8.74 $ 46,214 6.9 Granted 101,444 14.38 4.46 Exercised (243,775 ) 5.33 Forfeited (294,734 ) 9.47 Outstanding at December 31, 2017 8,024,761 8.89 40,634 6.0 Granted 187,080 14.63 4.98 Exercised (425,505 ) 5.33 Forfeited (859,162 ) 7.84 Outstanding at December 31, 2018 6,927,174 $ 9.39 $ 4,089 5.2 Exercisable at December 31, 2018 2,788,424 $ 11.05 $ (2,993 ) 5.4 Expected to vest at December 31, 2018 (excluding performance-based options) 1,103,550 $ 16.35 $ (7,031 ) 7.1 The intrinsic value of options exercised was $3,351, $1,972 and $2,726 for the years ended December 31, 2018, December 31, 2017, and December 31, 2016, respectively. The fair value of options vested was $2,819, $4,354, and $4,110, during the years ended December 31, 2018, December 31, 2017, and December 31, 2016, respectively. Restricted stock and Restricted Stock Units During 2018, the Company started granting restricted stock and restricted stock units to certain executives, senior leaders and the Company’s independent directors. To the extent that the awards vest, the participants receive shares of the Company’s stock. Of the awards that were granted, 201,270 awards vest solely based on service conditions. To the extent that such awards vest, one share of stock is issued for each award. Additionally, the Company granted awards which vest if certain cash flow and earnings per share targets are met. Depending on the achievement of such targets, a maximum of 1,217,974 shares could be issued due to such awards. The service-based awards vested 1/3 on January 1, 2019 and will vest 1/3 each on January 1, 2020 and January 1, 2021. During the year ended December 31, 2018, the Company recorded $1,174 of compensation expense related to the service-based awards. The performance-based awards vest if certain cash flow and earnings per share targets are met for the three-year period from January 1, 2018 to December 31, 2020. The Company recognizes compensation expense for such awards if it is probable that the performance conditions will be achieved. Based on the Company’s results for the year ended December 31, 2018 and its projections for the years ending December 31, 2019 and December 31, 2020, as of December 31, 2018 the Company concluded that it was not probable that such performance conditions will be met and, therefore, the Company did not record any compensation expense for the awards during the year ended December 31, 2018. The Company has based its estimated forfeiture rate for the restricted stock units and restricted stock on historical forfeitures for the Company’s time-based stock options as the number of awards given to each of the various levels of management is principally consistent with historical stock option grants and forfeitures are expected to be materially consistent with past experience. As of December 31, 2018, there was $1,817 of unrecognized compensation cost for the service-based awards.

Income Tax Disclosure [Abstract]
Income Taxes	Note 13 — Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“the Act”) was signed into law. The Act significantly changed U.S. tax law, including lowering the U.S. corporate income tax rate from 35% to 21%, effective January 1, 2018, and implementing a one-time “deemed repatriation” tax on unremitted earnings accumulated in non-U.S. jurisdictions since 1986 (the “Transition Tax”). Due to the complexities of accounting for the Act, the SEC issued Staff Accounting Bulletin (“SAB”) No. 118 which allowed entities to include a provisional estimate of the impact of the Act in their 2017 financial statements. Therefore, based on information that was available at the time, during the fourth quarter of 2017, the Company recorded a provisional estimate of the impact of the Act, which included an income tax benefit of $90,965 related to the remeasurement of its domestic net deferred tax liabilities and deferred tax assets due to the lower U.S. corporate tax rate. Additionally, during such quarter, the Company recorded a net income tax expense of $1,132 as its provisional estimate of the Transition Tax related to the deemed repatriation of unremitted earnings of foreign subsidiaries. During the fourth quarter of 2018, the Company finalized its assessment of the impact of the Act on the Company’s domestic net deferred tax liabilities and deferred tax assets and recorded an income tax benefit of $2,049. Additionally, during such quarter, the Company finalized its assessment of the Transition Tax and recorded additional income tax expense of $151. Additionally, the Act subjects a U.S. shareholder to current tax on “global intangible low-taxed income” (“GILTI”) of its controlled foreign corporations. GILTI is based on the excess of the aggregate of a U.S. shareholder’s pro rata share of net income of its controlled foreign corporations over a specified return. Under U.S. GAAP, an accounting policy election can be made to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years, or to provide for the tax expense related to GILTI in the year during which the tax is incurred as a period expense only. The Company has elected to account for GILTI in the year during which the tax is incurred. A summary of domestic and foreign income before income taxes follows: Year Ended 2018 Year Ended 2017 Year Ended 2016 Domestic $ 132,482 $ 153,280 $ 152,800 Foreign 29,115 34,864 33,914 Total $ 161,597 $ 188,144 $ 186,714 The income tax expense (benefit) consisted of the following: Year Ended 2018 Year Ended 2017 Year Ended 2016 Current: Federal $ 20,609 $ 61,890 $ 50,851 State 5,726 6,267 8,121 Foreign 7,870 7,298 6,864 Total current expense 34,205 75,455 65,836 Deferred: Federal 6,194 (101,774 ) 3,290 State (880 ) (796 ) (906 ) Foreign (741 ) (81 ) 1,017 Total deferred expense (benefit) 4,573 (102,651 ) 3,401 Income tax expense (benefit) $ 38,778 $ (27,196 ) $ 69,237 Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred income tax assets and liabilities consisted of the following: December 31, 2018 2017 Deferred income tax assets: Inventory reserves and capitalization $ 8,664 $ 7,064 Allowance for doubtful accounts 709 746 Accrued liabilities 7,087 8,130 Equity based compensation 3,431 3,145 Federal tax loss carryforwards 743 960 State tax loss carryforwards 1,554 1,726 Foreign tax loss carryforwards 14,034 14,151 Foreign tax credit carryforwards 5,397 6,412 Deferred rent and lease incentives 13,565 9,867 Other 3,433 166 Deferred income tax assets before valuation allowances 58,617 52,367 Less: valuation allowances (21,879 ) (24,073 ) Deferred income tax assets, net $ 36,738 $ 28,294 Deferred income tax liabilities: Depreciation $ 23,720 $ 13,855 Trade Name 145,767 145,066 Amortization of goodwill and other assets 38,712 42,297 Foreign earnings expected to be repatriated 1,132 586 Other 826 1,176 Deferred income tax liabilities $ 210,157 $ 202,980 The Company nets all of its deferred income tax assets and liabilities on a jurisdictional basis and classifies them as noncurrent on the balance sheet. In the Company’s December 31, 2018 consolidated balance sheet, $1,008 was included in “other assets, net” and $174,427 was included in deferred income tax liabilities. In the Company’s December 31, 2017 consolidated balance sheet, $1,150 was included in “other assets, net” and $175,836 was included in deferred income tax liabilities. Management assesses the available positive and negative evidence to estimate if sufficient taxable income will be generated to realize existing deferred tax assets. On the basis of this evaluation, a valuation allowance was recorded to reduce the total deferred tax assets to an amount that will, more-likely-than-not, be realized in the future. The valuation allowance, and the net change during the year, relate primarily to foreign net operating loss carryforwards and foreign tax credit carryforwards, the latter of which principally resulted from the Transition Tax. As of December 31, 2018, the Company had foreign tax-effected net operating loss carryforwards in Germany of $9,079, the United Kingdom of $3,740, and Australia of $589, all of which have an unlimited carryforward; as well as $626 from other foreign countries, which expire at different dates. In addition, the U.S. federal net operating loss carryforwards begin to expire in 2032, the U.S. state net operating loss carryforwards begin to expire in 2022 and the foreign tax credit carryforwards begin to expire in 2020. The difference between the Company’s effective income tax rate and the U.S. statutory income tax rate is as follows: Year Ended Year Ended Year Ended Tax provision at U.S. statutory income tax rate 21.0 % 35.0 % 35.0 % State income tax, net of federal income tax 2.4 1.9 2.5 Domestic production activities deduction 0.0 (1.4 ) (1.0 ) Valuation allowances 0.6 2.1 0.5 GILTI and Foreign-Derived Intangible Income 1.1 0.0 0.0 Foreign earnings 0.2 (1.7 ) 2.3 U.S. — foreign rate differential 0.4 (1.9 ) (2.4 ) Transition Tax on unremitted foreign earnings, net 0.1 0.6 0.0 Effect of the Act on Federal deferred income tax assets and liabilities (1.3 ) (48.4 ) 0.0 Other (0.5 ) (0.7 ) 0.2 Effective income tax rate 24.0 % (14.5 )% 37.1 % Transition Tax on Unremitted Foreign Earnings: Effect of the Act on Federal Deferred Income Tax Assets and Liabilities: Other differences between the effective income tax rate and the federal statutory income tax rate are composed primarily of reserves for unrecognized tax benefits, non-deductible meals and entertainment expenses, and benefits related to the exercise of stock options. The following table summarizes the activity related to the Company’s gross unrecognized tax benefits: Year Ended Year Ended Year Ended 2016 Balance at beginning of year $ 855 $ 913 $ 765 Increases related to current period tax positions 40 100 444 Increases (decreases) related to prior period tax positions 495 (158 ) 339 Decreases related to settlements 0 0 (635 ) Decreases related to lapsing of statutes of limitations (70 ) 0 0 Balance at end of year $ 1,320 $ 855 $ 913 The Company’s total unrecognized tax benefits that, if recognized, would impact the Company’s effective tax rate were $1,320 and $855 at December 31, 2018 and 2017, respectively. As of December 31, 2018, we do not believe that there are any positions for which it is reasonably possible that the total amount of unrecognized tax benefits will significantly increase or decrease within the next 12 months. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. The Company has accrued $129 and $73 for the potential payment of interest and penalties at December 31, 2018 and 2017, respectively. Such amounts are not included in the table above.

Quarterly Financial Information Disclosure [Abstract]
Quarterly Results	Note 16 — Quarterly Results (Unaudited) Despite a concentration of holidays in the fourth quarter of the year, as a result of the Company’s expansive product lines and customer base and increased promotional activities, the impact of seasonality on the quarterly results of the Company’s wholesale operations has been limited. However, due to Halloween and Christmas, the inventory balances of the Company’s wholesale operations are slightly higher during the third quarter than during the remainder of the year. Additionally, the promotional activities of the Company’s wholesale business, including special dating terms, particularly with respect to Halloween products sold to retailers and other distributors, result in slightly higher accounts receivable balances during the third quarter. The Company’s retail operations are subject to significant seasonal variations. Historically, the Company’s retail operations have realized a significant portion of their revenues, cash flow and net income in the fourth quarter of the year, principally due to Halloween sales in October and, to a lesser extent, year-end holiday sales. The following table sets forth our historical revenues, gross profit, income (loss) from operations, net income (loss), net income (loss) attributable to common shareholders of Party City Holdco Inc., and net income (loss) per share attributable to common shareholders of Party City Holdco Inc.—Basic and Diluted for each of the following quarters: For the Three Months Ended, 2018: March 31, June 30, September 30, December 31, Revenues: Net sales $ 505,108 $ 558,101 $ 550,840 $ 802,393 Royalties and franchise fees 2,716 2,910 2,206 3,241 Gross profit 188,142 228,624 201,199 363,119 Income from operations 22,256 65,451 31,738 158,840 Net (loss) income (1,163 ) 28,048 (2,440 ) 98,374 Net (loss) income attributable to common shareholders of Party City Holdco Inc.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 17 — Fair Value Measurements The provisions of ASC Topic 820, “Fair Value Measurement”, define fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 established a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. During 2017, the Company acquired a 28% ownership interest in Punchbowl, Inc. (“Punchbowl”), a provider of digital greeting cards and digital invitations. At such time, the Company provided Punchbowl’s other investors with the ability to “put” their interest in Punchbowl to the Company at a future date. The Company is adjusting such put liability to fair value on a recurring basis. The liability represents a Level 3 fair value measurement as it is based on unobservable inputs. During 2017, the Company and Ampology, a subsidiary of Trivergence, reached an agreement to form a new legal entity, Kazzam, LLC (“Kazzam”), for the purpose of designing, developing and launching an online exchange platform for party-related services. As part of Ampology’s compensation for designing, developing and launching the exchange platform, Ampology received an ownership interest in Kazzam. The interest has been recorded as redeemable securities in the mezzanine of the Company’s consolidated balance sheet as, in the future, Ampology has the right to cause the Company to purchase the interest. On a recurring basis, the liability is adjusted to the greater of the current fair value or the original fair value at the time at which the ownership interest was issued (adjusted for any subsequent changes in the ownership interest percentage). As of December 31, 2018, the original value was greater and, therefore, the liability is not included in the table below. As of December 31, 2017, the then current fair value was greater and, therefore, the liability is included in the table below. Such amount represents a Level 3 fair value measurement as it is based on unobservable inputs. The following table shows assets and liabilities as of December 31, 2018 that are measured at fair value on a recurring basis: Level 1 Level 2 Level 3 Total as of Derivative assets $ 0 $ 115 $ 0 $ 115 Derivative liabilities 0 0 0 0 Punchbowl put liability 0 0 316 316 The following table shows assets and liabilities as of December 31, 2017 that are measured at fair value on a recurring basis: Level 1 Level 2 Level 3 Total as of Derivative assets $ 0 $ 95 $ 0 $ 95 Derivative liabilities 0 99 0 99 Kazzam liability 0 0 3,590 3,590 Punchbowl put liability 0 0 2,122 2,122 Certain amounts in the December 31, 2017 table above have been adjusted to conform with current year presentation. The majority of the Company’s non-financial instruments, which include goodwill, intangible assets, inventories and property, plant and equipment, are not required to be carried at fair value on a recurring basis. However, if certain triggering events occur (or at least annually for goodwill and indefinite-lived intangible assets), a non-financial instrument is required to be evaluated for impairment. If the Company determines that the non-financial instrument is impaired, the Company would be required to write down the non-financial instrument to its fair value. The carrying amounts for cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other current liabilities approximated fair value at December 31, 2018 because of the short-term maturities of the instruments and/or their variable rates of interest. The carrying amounts and fair values of borrowings under the Term Loan Credit Agreement and the senior notes as of December 31, 2018 are as follows: Carrying Amount Fair Value Term Loan Credit Agreement $ 791,135 $ 765,920 6.125% Senior Notes — due 2023 346,191 343,662 6.625% Senior Notes — due 2026 494,138 452,235 The fair values of the Term Loan Credit Agreement and the senior notes represent Level 2 fair value measurements as the debt instruments trade in inactive markets. The carrying amounts for other long-term debt approximated fair value at December 31, 2018 based on the discounted future cash flows of each instrument at rates currently offered for similar debt instruments of comparable maturity.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 18 — Derivative Financial Instruments The Company is directly and indirectly affected by changes in certain market conditions. These changes in market conditions may adversely impact the Company’s financial performance and are referred to as market risks. The Company, when deemed appropriate, uses derivatives as a risk management tool to mitigate the potential impact of certain market risks. The primary market risks managed through the use of derivative financial instruments are interest rate risk and foreign currency exchange rate risk. Interest Rate Risk Management As part of the Company’s risk management strategy, the Company periodically uses interest rate swap agreements to hedge the variability of cash flows on floating rate debt obligations. Accordingly, interest rate swap agreements are reflected in the consolidated balance sheets at fair value and the related gains and losses on these contracts are deferred in equity and recognized in interest expense over the same period in which the related interest payments being hedged are recognized in income. The Company did not utilize interest rate swap agreements during the years ended December 31, 2018, December 31, 2017 or December 31, 2016. Foreign Exchange Risk Management A portion of the Company’s cash flows is derived from transactions denominated in foreign currencies. In order to reduce the uncertainty of foreign exchange rate movements on transactions denominated in foreign currencies, including the British Pound Sterling, the Canadian Dollar, the Euro, the Malaysian Ringgit, the Australian Dollar, and the Mexican Peso, the Company enters into foreign exchange contracts with major international financial institutions. These forward contracts, which typically mature within one year, are designed to hedge anticipated foreign currency transactions, primarily inventory purchases and sales. For contracts that qualify for hedge accounting, the terms of the foreign exchange contracts are such that cash flows from the contracts should be highly effective in offsetting the expected cash flows from the underlying forecasted transactions. The foreign currency exchange contracts are reflected in the consolidated balance sheets at fair value. At December 31, 2018 and 2017, the Company had foreign currency exchange contracts that qualified for hedge accounting. No components of these agreements were excluded in the measurement of hedge effectiveness. As these hedges are 100% effective, there is no current impact on earnings due to hedge ineffectiveness. The Company anticipates that substantially all unrealized gains and losses in accumulated other comprehensive loss related to these foreign currency exchange contracts will be reclassified into earnings by June 2020. The following table displays the fair values of the Company’s derivatives at December 31, 2018 and December 31, 2017: Derivative Assets Derivative Liabilities December 31, 2018 December 31, 2017 December 31, 2018 December 31, 2017 Balance Fair Balance Fair Balance Fair Balance Fair Foreign Exchange Contracts (a) PP $115 (a) PP $95 (b) AE $0 (b) AE $99 (a) PP = Prepaid expenses and other current assets (b) AE = Accrued expenses The following table displays the notional amounts of the Company’s derivatives at December 31, 2018 and December 31, 2017: Derivative Instrument December 31, December 31, Foreign Exchange Contracts $ 10,942 $ 21,672

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Note 20 — Revenue from Contracts with Customers In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. The pronouncement contains a five-step model which replaces most existing revenue recognition guidance. The Company adopted the standard on January 1, 2018 via a modified retrospective approach and recognized the cumulative effect of the adoption as an adjustment to January 1, 2018 retained earnings. Revenue Transactions — Retail Revenue from retail store operations is recognized at the point of sale as control of the product is transferred to the customer at such time. Retail e-commerce sales are recognized when the consumer receives the product as control transfers upon delivery. Due to its extensive history operating as the largest party goods retailer in North America, the Company has sufficient history with which to estimate future retail sales returns and it uses the expected value method to estimate such activity. The transaction price for the majority of the Company’s retail sales is based on either: 1) the item’s stated price or 2) the stated price adjusted for the impact of a coupon which can only be applied to such transaction. To the extent that the Company charges customers for freight costs on e-commerce sales, the Company records such amounts in revenue. The Company has chosen the pronouncement’s policy election which allows it to exclude all sales taxes and value-added taxes from revenue. Under the terms of its agreements with its franchisees, the Company provides both: 1) brand value (via significant advertising spend) and 2) support with respect to planograms, in exchange for a royalty fee that ranges from 4% to 6% of the franchisees’ sales. The Company records the royalty fees at the time that the franchisees’ sales are recorded. Additionally, although the Company anticipates that future franchise store openings will be limited, when a franchisee opens a new store, the Company receives and records a one-time fee which is earned by the Company for its assistance with site selection and development of the new location. Both the sales-based royalty fee and the one-time fee are recorded in royalties and franchise fees in the Company’s consolidated statement of operations and comprehensive income. Revenue Transactions — Wholesale For most of the Company’s wholesale sales, control transfers upon the Company’s shipment of the product. Wholesale sales returns are not significant as the Company generally only accepts the return of goods that were shipped to the customer in error or that were damaged when received by the customer. Additionally, due to its extensive history operating as a leading party goods wholesaler, the Company has sufficient history with which to estimate future sales returns. In most cases, the determination of the transaction price is fixed based on the contract and/or purchase order. To the extent that the Company charges customers for freight costs, the Company records such amounts in revenue. The Company has chosen the pronouncement’s policy election which allows it to exclude all sales taxes and value-added taxes from revenue. The majority of the sales for the Company’s wholesale business are due within 30 to 120 days from the transfer of control of the product and substantially all of the sales are collected within a year from such transfer. For all transactions for which the Company expects to collect the transaction price within a year from the transfer of control, the Company applies one of the pronouncement’s practical expedients and does not adjust the consideration for the effects of a significant financing component. Judgments Although most of the Company’s revenue transactions consist of fixed transaction prices and the transfer of control at either the point of sale (for retail) or when the product is shipped (for wholesale), certain transactions involve a limited number of judgments. For transactions for which control transfers to the customer when the freight carrier delivers the product to the customer, the Company estimates the date of such receipt based on historical shipping times. Additionally, the Company utilizes historical data to estimate sales returns. Due to its extensive history operating as a leading party goods retailer, the Company has sufficient history with which to estimate such amounts. Other Revenue Topics During the years ended December 31, 2018, December 31, 2017, and December 31, 2016, impairment losses recognized on receivables and contract assets arising from the Company’s contracts with customers were immaterial. As a significant portion of the Company’s revenue is either: 1) part of a contract with an original expected duration of one year or less, or 2) related to sales-based royalties promised in exchange for licenses of intellectual property, the Company has elected to apply the optional exemptions in paragraphs ASC 606-10-50-14 through ASC 606-10-50-14A. Additionally, the Company has elected to apply the practical expedient which allows companies to recognize the incremental costs of obtaining a contract as an expense if the amortization period of the asset that the entity otherwise would have recognized would have been one year or less. Disaggregation of Revenue The following table summarizes revenue from contracts with customers for the years ended December 31, 2018, December 31, 2017, and December 31, 2016: Year Ended December 31, 2018 Year Ended December 31, 2017 Year Ended December 31, 2016 Retail Net Sales: Party City Stores $ 1,583,134 $ 1,521,661 $ 1,429,435 Global E-commerce 154,481 152,465 152,876 Temporary Stores 65,219 54,463 58,757 Total Retail Net Sales $ 1,802,834 $ 1,728,589 $ 1,641,068 Royalties and Franchise Fees 11,073 13,583 17,005 Total Retail Revenue $ 1,813,907 $ 1,742,172 $ 1,658,073 Wholesale Net Sales: Domestic $ 328,056 $ 351,109 $ 381,999 International 285,552 278,288 243,319 Total Wholesale Net Sales $ 613,608 $ 629,397 $ 625,318 Total Consolidated Revenue $ 2,427,515 $ 2,371,569 $ 2,283,391 Financial Statement Impact of Adopting the Pronouncement All of the Company’s revenue is recognized from contracts with customers and, therefore, is subject to the pronouncement. The Company adopted the pronouncement using a modified retrospective approach and applied the guidance to all contracts as of January 1, 2018. On such date, the Company reduced its retained earnings by $78, reduced its accounts receivable by $141, increased its inventory by $11, reduced its accrued expenses by $26, increased its deferred tax asset by $28 and increased its income taxes payable by $2. The cumulative adjustment principally related to certain discounts within the Company’s wholesale business. Additionally, the adoption of the pronouncement impacted the Company’s financial statements for the year ended December 31, 2018 as it decreased pre-tax income by $22 during the period.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Kazzam, LLC	Note 21 — Kazzam, LLC During the first quarter of 2017, the Company and Ampology, a subsidiary of Trivergence, reached an agreement to form a new legal entity, Kazzam, LLC (“Kazzam”), for the purpose of designing, developing and launching an online exchange platform for party-related services. The website allows consumers to select, schedule and pay for various services (including entertainment, activities and food) all through a single portal. Although the Company currently owns only 26% of Kazzam’s equity, the Company has concluded that: a) Kazzam is a variable interest entity as it has insufficient equity at risk, and b) the Company is its primary beneficiary. Therefore, the Company has consolidated Kazzam into the Company’s financial statements. Further, as the Company is currently funding all of Kazzam’s start-up activities via a loan to Kazzam (which will be repaid when the venture is profitable), the Company is recording 100% of Kazzam’s operating results in “development stage expenses” in the Company’s consolidated statement of operations and comprehensive income. As part of Ampology’s compensation for designing, developing and launching the exchange platform, Ampology received an ownership interest in Kazzam. The interest has been recorded in redeemable securities in the mezzanine of the Company’s consolidated balance sheet as, in the future, Ampology has the right to cause the Company to purchase the interest.

Restricted Cash	Note 22 — Restricted Cash In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows: Restricted Cash”. The pronouncement requires companies to show changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in their statement of cash flows. The Company adopted the pronouncement, which requires retrospective application, during the first quarter of 2018. As a result, the Company’s statement of cash flows for the year ended December 31, 2017 has been adjusted to include $155 of restricted cash at December 31, 2016 and $117 of restricted cash at December 31, 2017. The restricted cash, which principally relates to funds that are required to be spent on advertising, is included in “prepaid expenses and other current assets” in the Company’s consolidated balance sheet. Therefore, in the Company’s adjusted consolidated statement of cash flows for the year ended December 31, 2017, the change in “prepaid expenses and other current assets” has been adjusted from a cash outflow of $9,079 to a cash outflow of $9,117. Additionally, the Company’s statement of cash flows for the year ended December 31, 2016 has been adjusted to include $173 of restricted cash at December 31, 2015 and $155 of restricted cash at December 31, 2016 and the change in “prepaid expenses and other current assets” has been adjusted from a cash outflow of $14,499 to a cash outflow of $14,517. The Company’s December 31, 2018 consolidated balance sheet included $58,909 of cash and cash equivalents and $310 of restricted cash, and the Company’s December 31, 2017 consolidated balance sheet included $54,291 of cash and cash equivalents and $117 of restricted cash. Restricted cash is recorded in “prepaid expenses and other current assets”.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Consolidated Financial Statements	Consolidated Financial Statements The consolidated financial statements of the Company include the accounts of all majority-owned subsidiaries and controlled entities. All intercompany balances and transactions have been eliminated. The Company’s retail operations define a fiscal year (“Fiscal Year”) as the 52-week period or 53-week period ended on the Saturday nearest December 31st of each year, and define their fiscal quarters (“Fiscal Quarter”) as the four interim 13-week periods following the end of the previous Fiscal Year, except in the case of a 53-week Fiscal Year when the fourth Fiscal Quarter is extended to 14 weeks. The consolidated financial statements of the Company combine the Fiscal Year and Fiscal Quarters of the Company’s retail operations with the calendar year and calendar quarters of the Company’s wholesale operations, as the differences are not significant.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Management periodically evaluates estimates used in the preparation of the consolidated financial statements for continued reasonableness. Appropriate adjustments, if any, to the estimates used are made prospectively based on such periodic evaluations.
Cash Equivalents	Cash Equivalents Highly liquid investments with a maturity of three months or less when purchased are considered to be cash equivalents. All credit card transactions that process in less than seven days are classified as cash and cash equivalents.
Inventories	Inventories Inventories are valued at the lower of cost and net realizable value. In assessing the ultimate realization of inventories, the Company makes judgments regarding, among other things, future demand and market conditions, current inventory levels and the impact of the possible discontinuation of product designs. The Company principally determines the cost of inventory using the weighted average method. The Company estimates retail inventory shrinkage for the period between physical inventory dates on a store-by-store basis. Inventory shrinkage estimates can be affected by changes in merchandise mix and changes in actual shortage trends. The shrinkage rate from the most recent physical inventory, in combination with historical experience, is the basis for estimating shrinkage.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of the Company’s customers to make required payments. Judgment is required in assessing the ultimate realization of these receivables, including consideration of the Company’s history of receivable write-offs, the level of past due accounts and the economic status of the Company’s customers. In an effort to identify adverse trends relative to customer economic status, the Company assesses the financial health of the markets it operates in and performs periodic credit evaluations of its customers and ongoing reviews of account balances and aging of receivables. Amounts are considered past due when payment has not been received within the time frame of the credit terms extended. Write-offs are charged directly against the allowance for doubtful accounts and occur only after all collection efforts have been exhausted. At December 31, 2018 and 2017, the allowance for doubtful accounts was $2,933 and $2,971, respectively.
Long-Lived and Intangible Assets (including Goodwill)	Long-Lived and Intangible Assets (including Goodwill) Property, plant and equipment are stated at cost. Equipment under capital leases is stated at the present value of the minimum lease payments at the inception of the lease. Depreciation is calculated principally on the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or the estimated useful life of the asset. The Company reviews the recoverability of its finite long-lived assets, including finite-lived intangible assets, whenever facts and circumstances indicate that the carrying amount may not be fully recoverable. For purposes of recognizing and measuring impairment, the Company evaluates long-lived assets/asset groups, other than goodwill, based upon the lowest level of independent cash flows ascertainable to evaluate impairment. If an impairment indicator exists, we compare the undiscounted future cash flows of the asset/asset group to the carrying value of the asset/asset group. If the sum of the undiscounted future cash flows is less than the carrying value of the asset/asset group, the Company would recognize an impairment loss. The impairment related to long-lived assets is measured as the amount by which the carrying amount of the asset(s) exceeds the fair value of the asset(s). In the evaluation of the fair value and future benefits of finite long-lived assets attached to retail stores, the Company performs its cash flow analysis on a store-by-store basis. Various factors including future sales growth and profit margins are included in this analysis. Goodwill represents the excess of the purchase price of acquired entities over the estimated fair value of the net assets acquired. Goodwill and other intangibles with indefinite lives are not amortized, but are reviewed for impairment annually or more frequently if certain impairment indicators arise. The Company evaluates the goodwill associated with its acquisitions, and other intangibles with indefinite lives, for impairment as of the first day of its fourth quarter based on current and projected performance. For purposes of testing goodwill for impairment, reporting units are determined by identifying individual components within the Company’s organization which constitute a business for which discrete financial information is available and is reviewed by management. Components within a segment are aggregated to the extent that they have similar economic characteristics. Based on this evaluation, the Company has determined that its operating segments, wholesale and retail, represent reporting units for the purposes of its goodwill impairment test. If it is concluded that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company estimates the fair value of the reporting unit using a combination of a market approach and an income approach. If such carrying value exceeds the fair value an impairment loss will be recognized in an amount equal to such excess. The fair value of a reporting unit refers to the amount at which the unit as a whole could be sold in a current transaction between willing parties.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs are netted against amounts outstanding under the related debt instruments. They are amortized to interest expense over the terms of the instruments using the effective interest method.
Deferred Rent and Rental Expenses	Deferred Rent and Rental Expenses The Company leases its retail stores under operating leases that generally have initial terms of ten years, with two five year renewal options. The Company’s leases may have early cancellation clauses, which permit the lease to be terminated if certain sales levels are not met in specific periods, and may provide for the payment of contingent rent based on a percentage of the store’s net sales. The Company’s lease agreements generally have defined escalating rent provisions, which are reported as a deferred rent liability and expensed on a straight-line basis over the term of the related lease, commencing with the date of possession. In addition, the Company may receive cash allowances from its landlords on certain properties, which are reported as deferred rent and amortized to rent expense over the term of the lease, also commencing with the date of possession. The Company’s deferred rent liability at December 31, 2018 and 2017 was $81,634 and $76,994, respectively.
Equity Method Investments	Equity Method Investments The Company has an investment in Convergram Mexico, S. De R.L. De C.V., a joint venture distributing metallic balloons, principally in Mexico and Latin America. The Company accounts for its 49.9% investment in the joint venture using the equity method of accounting. Additionally, the Company has an investment in PD Retail Group Limited, a joint venture operating party goods stores in the United Kingdom (“U.K.”). The Company accounts for its 50% investment using the equity method of accounting. Further, the Company has a 28% ownership interest in Punchbowl, Inc., a provider of digital greeting cards and digital invitations. The Company is also accounting for such investment under the equity method. The Company’s investments are included in other assets on the consolidated balance sheet and the results of the investees’ operations are included in other expense (income) in the consolidated statement of operations and comprehensive income (loss) (see Note 10).
Insurance Accruals	Insurance Accruals The Company maintains certain self-insured workers’ compensation and general liability insurance plans. The Company estimates the required liability for claims under such plans based upon various assumptions, which include, but are not limited to, historical loss experience, projected loss development factors, actual payroll and other data. The required liability is also subject to adjustment in the future based upon changes in claims experience, including changes in the number of incidents (frequency) and changes in the ultimate cost per incident (severity).
Revenue Recognition	Revenue Recognition Retail Revenue from retail store operations is recognized at the point of sale as control of the product is transferred to the customer at such time. Retail e-commerce sales are recognized when the consumer receives the product as control transfers upon delivery. Due to its extensive history operating as the largest party goods retailer in North America, the Company has sufficient history with which to estimate future retail sales returns and it uses the expected value method to estimate such activity. The transaction price for the majority of the Company’s retail sales is based on either: 1) the item’s stated price or 2) the stated price adjusted for the impact of a coupon which can only be applied to such transaction. To the extent that the Company charges customers for freight costs on e-commerce sales, the Company records such amounts in revenue. The Company excludes all sales taxes and value-added taxes from revenue. Under the terms of its agreements with its franchisees, the Company provides both: 1) brand value (via significant advertising spend) and 2) support with respect to planograms, in exchange for a royalty fee that ranges from 4% to 6% of the franchisees’ sales. The Company records the royalty fees at the time that the franchisees’ sales are recorded. Additionally, although the Company anticipates that future franchise store openings will be limited, when a franchisee opens a new store, the Company receives and records a one-time fee which is earned by the Company for its assistance with site selection and development of the new location. Both the sales-based royalty fee and the one-time fee are recorded in royalties and franchise fees in the Company’s consolidated statement of operations and comprehensive income. Wholesale For most of the Company’s wholesale sales, control transfers upon the Company’s shipment of the product. Wholesale sales returns are not significant as the Company generally only accepts the return of goods that were shipped to the customer in error or that were damaged when received by the customer. Additionally, due to its extensive history operating as a leading party goods wholesaler, the Company has sufficient history with which to estimate future sales returns. In most cases, the determination of the transaction price is fixed based on the contract and/or purchase order. To the extent that the Company charges customers for freight costs, the Company records such amounts in revenue. The Company excludes all sales taxes and value-added taxes from revenue. The majority of the sales for the Company’s wholesale business are due within 30 to 120 days from the transfer of control of the product and substantially all of the sales are collected within a year from such transfer. For all transactions for which the Company expects to collect the transaction price within a year from the transfer of control, the Company does not adjust the consideration for the effects of a significant financing component.
Cost of Sales/Shipping and Handling	Cost of Sales Cost of sales at wholesale reflects the production costs (i.e., raw materials, labor and overhead) of manufactured goods and the direct cost of purchased goods, inventory shrinkage, inventory adjustments, inbound freight to the Company’s manufacturing and distribution facilities, distribution costs and outbound freight to transfer goods to the Company’s wholesale customers. At retail, cost of sales reflects the direct costs of goods purchased from third parties and the production costs/purchase costs of goods acquired from the Company’s wholesale operations. Retail cost of sales also includes inventory shrinkage, inventory adjustments, inbound freight, occupancy costs related to store operations (such as rent, utilities and common area maintenance), depreciation on assets and all logistics costs (i.e., handling and distribution costs) associated with the Company’s e-commerce business.
Retail Operating Expenses	Retail Operating Expenses Retail operating expenses include costs associated with the operation of the Company’s retail stores (with the exception of occupancy costs, which are included in cost of sales). Retail operating expenses principally consist of employee compensation and benefits, advertising, supplies expense and credit card fees.
Product Royalty Agreements	Product Royalty Agreements The Company enters into product royalty agreements that allow the Company to use licensed designs on certain of its products. These contracts require the Company to pay royalties, generally based on the sales of such product, and may require guaranteed minimum royalties, a portion of which may be paid in advance. The Company matches royalty expense with revenue by recording royalties at the time of sale, at the greater of the contractual rate or an effective rate calculated based on the guaranteed minimum royalty and the Company’s estimate of sales during the contract period. If a portion of the guaranteed minimum royalty is determined to be unrecoverable, the unrecoverable portion is charged to expense at that time. Guaranteed minimum royalties paid in advance are recorded in the consolidated balance sheets in either prepaid expenses and other current assets or other assets, depending on the nature of the royalties.
Catalog Costs	Catalog Costs The Company expenses costs associated with the production of catalogs when incurred.
Advertising	Advertising Advertising costs are expensed as incurred. Retail advertising expenses for the years ended December 31, 2018, December 31, 2017, and December 31, 2016 were $68,756, $61,187, and $63,528, respectively.
Variable Interest Entities	Variable Interest Entities When determining whether a legal entity should be consolidated, the Company first determines whether it has a variable interest in the legal entity. If a variable interest exists, the Company determines whether the legal entity is a variable interest entity due to either: 1) a lack of sufficient equity to finance its activities, 2) the equity holders lacking the characteristics of a controlling financial interest, or 3) the legal entity being structured with non-substantive voting rights. If the Company concludes that the legal entity is a variable interest entity, the Company next determines whether it is the primary beneficiary due to it possessing both: 1) the power to direct the activities of a variable interest entity that most significantly impact the variable interest entity’s economic performance, and 2) the obligation to absorb losses of the variable interest entity that potentially could be significant to the variable interest entity or the right to receive benefits from the variable interest entity which could be significant to the variable interest entity. If the Company concludes that it is the primary beneficiary, it consolidates the legal entity. During 2017, the Company and Ampology, a subsidiary of Trivergence, reached an agreement to form a new legal entity, Kazzam, LLC (“Kazzam”), for the purpose of designing, developing and launching an online exchange platform for party-related services. Although the Company currently only owns 26% of Kazzam’s equity, the Company has concluded that: a) Kazzam is a variable interest entity as it has insufficient equity at risk, and b) the Company is its primary beneficiary. Therefore, the Company has consolidated Kazzam into the Company’s financial statements. As part of Ampology’s compensation for designing, developing and launching the exchange platform, Ampology received an ownership interest in Kazzam. The interest has been recorded as redeemable securities in the mezzanine of the Company’s consolidated balance sheet as, in the future, Ampology has the right to cause the Company to purchase the interest. On a recurring basis, the mezzanine liability is adjusted to the greater of: a) the interest’s carrying amount under Accounting Standards Codification (“ASC”) Topic 810, “Consolidation”, or b) the fair value of the interest.
Art and Development Costs	Art and Development Costs Art and development costs are primarily internal costs that are not easily associated with specific designs, some of which may not reach commercial production. Accordingly, the Company expenses these costs as incurred.
Derivative Financial Instruments	Derivative Financial Instruments ASC Topic 815, “Accounting for Derivative Instruments and Hedging Activities”, requires that all derivative financial instruments be recognized on the balance sheet at fair value and establishes criteria for both the designation and effectiveness of hedging activities. The Company uses derivatives in the management of interest rate and foreign currency exposure. ASC Topic 815 requires the Company to formally document the assets, liabilities or other transactions the Company designates as hedged items, the risk being hedged and the relationship between the hedged items and the hedging instruments. The Company must measure the effectiveness of the hedging relationship at the inception of the hedge and on an on-going basis. If derivative financial instruments qualify as fair value hedges, the gain or loss on the instrument and the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in net income during the period of the change in fair values. For derivative financial instruments that qualify as cash flow hedges ( i.e i.e
Income Taxes	Income Taxes Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities (and operating loss and tax credit carryforwards) applying enacted statutory tax rates in effect for the years in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance when, in the judgment of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.
Stock-Based Compensation	Stock-Based Compensation Accounting for stock-based compensation requires measurement of compensation cost for all stock-based awards at fair value on the date of grant and recognition of compensation expense over the service period for awards expected to vest.
Accumulated Other Comprehensive Loss	Accumulated Other Comprehensive Loss Accumulated other comprehensive loss consists of the Company’s foreign currency adjustments and the impact of interest rate swap and foreign exchange contracts that qualify as hedges (see Notes 18 and 19).
Foreign Currency Transactions and Translation	Foreign Currency Transactions and Translation The functional currencies of the Company’s foreign operations are the local currencies in which they operate. Foreign currency exchange gains or losses resulting from receivables or payables in currencies other than the functional currencies generally are recognized in the Company’s statement of operations and comprehensive income (loss). The balance sheets of foreign subsidiaries are translated into U.S. dollars at the exchange rates in effect on the balance sheet date. The results of operations of foreign subsidiaries are translated into U.S. dollars at the average exchange rates effective for the periods presented. The differences from historical exchange rates are recorded as comprehensive income (loss) and are included as a component of accumulated other comprehensive loss.
Earnings Per Share	Earnings Per Share Basic earnings per share are computed by dividing net income attributable to common shareholders of Party City Holdco Inc. by the weighted average number of common shares outstanding for the period. Diluted earnings per share are calculated based on the weighted average number of outstanding common shares plus the dilutive effect of stock options and warrants, as if they were exercised, and restricted stock units, as if they vested. A reconciliation between basic and diluted income per share is as follows: Year Ended Year Ended Year Ended 2016 Net income attributable to common shareholders of Party City Holdco Inc.: $ 123,259 $ 215,340 $ 117,477 Weighted average shares — Basic: 96,133,144 118,589,421 119,381,842 Effect of dilutive restricted stock units: 9,661 0 0 Effect of dilutive stock options: 1,128,245 1,304,600 987,830 Weighted average shares — Diluted: 97,271,050 119,894,021 120,369,672 Net income per share attributable to common shareholders of Party City Holdco Inc. — Basic: $ 1.28 $ 1.81 $ 0.98 Net income per share attributable to common shareholders of Party City Holdco Inc. — Diluted: $ 1.27 $ 1.79 $ 0.98 During the years ended December 31, 2018, December 31, 2017, and December 31, 2016, 2,394,868 stock options, 2,392,150 stock options and 2,371,876 stock options, respectively, were excluded from the calculations of net income per share attributable to common shareholders of Party City Holdco Inc. – diluted as they were anti-dilutive.

Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-07, “Compensation — Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting”. The ASU simplifies the accounting for non-employee share-based payments. The update is effective for the Company during the first quarter of 2019. Although the Company continues to evaluate this pronouncement, it does not believe that it will have a material impact on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities”. The pronouncement amends the existing hedge accounting model in order to enable entities to better portray the economics of their risk management activities in their financial statements. The update is effective for the Company during the first quarter of 2019. Although the Company continues to evaluate this pronouncement, it does not believe that it will have a material impact on the Company’s consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows: Restricted Cash”. The pronouncement requires companies to show changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. The Company adopted the pronouncement, which requires retrospective application, during the first quarter of 2018. The impact of such adoption was immaterial to the Company’s consolidated financial statements. See Note 22 for further discussion. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments”. The pronouncement clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The Company adopted the pronouncement during the first quarter of 2018 and such adoption did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases”. The ASU requires that companies recognize assets and liabilities for the rights and obligations created by companies’ leases. The update is effective for the Company during the first quarter of 2019. The Company’s current lease portfolio is primarily comprised of store leases, manufacturing and distribution facility leases and office leases. Most of the Company’s leases are operating leases. The Company’s finance leases are not material to its consolidated financial statements. Upon adoption of this standard, the Company will recognize a right of use asset and liability related to substantially all of its operating lease arrangements with terms of greater than twelve months. The Company established a cross-functional team to implement the pronouncement and the team has finalized the implementation of a new software solution and its assessment of the practical expedients and policy elections offered by the standard. Due to the nature of the Company’s business, it is often executing new leases and amending existing leases. Currently, the Company estimates that its right of use asset for its operating leases will be in the range of $740,000 to $820,000. Additionally, the Company currently estimates that its liability for its operating leases will be in the range of $820,000 to $900,000. The adoption of the pronouncement will not have a material impact on the Company’s consolidated statement of operations and comprehensive income and it will not impact the Company’s compliance with its debt covenants. The FASB has provided companies with a transition option under which they can opt to continue to apply legacy guidance in comparative periods and recognize a cumulative effect adjustment to January 1, 2019 retained earnings (if applicable). The Company has elected the option. The cumulative effect adjustment will not have a material impact on the Company’s consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments — Overall: Recognition and Measurement of Financial Assets and Financial Liabilities”. The update impacts the accounting for equity investments and the recognition of changes in fair value of financial liabilities when the fair value option is elected. The Company adopted the pronouncement during the first quarter of 2018 and such adoption had no impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. The pronouncement contains a five-step model which replaces most existing revenue recognition guidance. The new standard became effective for the Company on January 1, 2018. The Company adopted the pronouncement using the modified retrospective approach. Therefore, on January 1, 2018, the Company adjusted its accounting for certain discounts which are related to the timing of payments by customers of its wholesale business and the Company recorded a cumulative-effect adjustment which reduced retained earnings by $46. Additionally, as of such date, the Company modified its accounting for certain metallic balloon sales of its wholesale segment and started to defer the recognition of revenue on such sales, and the related costs, until the balloons have been filled with helium. As a result, the Company recorded a cumulative-effect adjustment which increased retained earnings by $8. Finally, as of such date, the Company adjusted its accounting for certain discounts on wholesale sales of seasonal product and the Company recorded a cumulative-effect adjustment which reduced retained earnings by $40. See Note 20 for further discussion of the adoption of the pronouncement and the Company’s revenue recognition policy.
Industry Segments	Industry Segments The Company has two identifiable business segments. The Wholesale segment designs, manufactures, contracts for manufacture and distributes party goods, including paper and plastic tableware, metallic and latex balloons, Halloween and other costumes, accessories, novelties and stationery throughout the world. The Retail segment operates specialty retail party supply stores in the United States and Canada, principally under the names Party City and Halloween City, and it operates e-commerce websites, principally through the domain name PartyCity.com.
Fair Value Measurement	The provisions of ASC Topic 820, “Fair Value Measurement”, define fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 established a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.
