General - Basis of Presentation | 1. General — Basis of Presentation We own and operate regional theme parks and waterparks and are the largest regional theme park operator in the world and the largest operator of waterparks in North America based on the number of parks we operate. Of the 26 parks we owned or operated as of June 30, 2019, 23 parks are located in the United States, two are located in Mexico and one is located in Montreal, Canada. The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed, or omitted, pursuant to the rules and regulations of the SEC. "Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations" contains a discussion of our results of operations and our financial position and should be read in conjunction with the unaudited condensed consolidated financial statements and notes. The 2018 Annual Report includes additional information about us, our operations and our financial position, and should be referred to in conjunction with this Quarterly Report. The information furnished in this Quarterly Report reflects all normal and recurring adjustments that are, in the opinion of management, necessary to present a fair statement of the results for the periods presented. Results of operations for the six months ended June 30, 2019 are not indicative of the results expected for the full year. In particular, our park operations contribute more than half of their annual revenue during the period from Memorial Day to Labor Day each year, while expenses are incurred year-round. Additionally, we had increased costs in the current year related to the operations of the five new parks that we began operating on June 1, 2018 and Magic Waters, a waterpark in Rockford, Illinois that we began operating on April 1, 2019. a. Consolidated U.S. GAAP Presentation Our accounting policies reflect industry practices and conform to U.S. GAAP. The unaudited condensed consolidated financial statements include our accounts and the accounts of our wholly owned subsidiaries. We also consolidate the partnerships that own Six Flags Over Texas ("SFOT") and Six Flags Over Georgia (including Six Flags White Water Atlanta) ("SFOG", and together with SFOT, the "Partnership Parks") as subsidiaries in our unaudited condensed consolidated financial statements, as we have determined that we have the power to direct the activities of the Partnership Parks that most significantly impact their economic performance and we have the obligation to absorb losses and receive benefits from the Partnership Parks that can be potentially significant to these entities. The equity interests owned by non-affiliated parties in the Partnership Parks are reflected in the accompanying unaudited condensed consolidated balance sheets as redeemable noncontrolling interests. See Note 6 for a description of the partnership agreements applicable to the Partnership Parks and Note 8 for further discussion on the non-affiliated parties’ share of the earnings of the Partnership Parks. b. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, including net operating loss and other tax carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. We recorded a valuation allowance of $116.8 million and $115.2 million as of June 30, 2019 and December 31, 2018, respectively, due to uncertainties related to our ability to use some of our deferred tax assets, primarily consisting of certain state net operating loss and other tax carryforwards, before they expire. The valuation allowance was based on our estimates of taxable income by jurisdiction in which we operate and the period over which our deferred tax assets were recoverable. Our projected taxable income over the foreseeable future gives us comfort that we will be able to use all of our federal net operating loss carryforwards before they expire. In determining the effective tax rate for interim periods, we consider the expected changes in our valuation allowance from current year originating or reversing timing differences between financial accounting and tax purposes and the taxable income or loss expected for the current year. For interim periods, we also account for the tax effect of significant non-recurring items in the period in which they occur as well as changes in the valuation allowance relating to a change in the assessment of the probability of utilization of the deferred income tax assets. Our liability for income taxes is finalized as auditable tax years pass their respective statutes of limitations in the various jurisdictions in which we are subject to tax. However, taxing authorities of these jurisdictions may audit prior years for which the statute of limitations is closed for the purpose of making an adjustment to our taxable income in a year for which the statute of limitations has not closed. Accordingly, taxing authorities of these jurisdictions may audit prior years of the Company and its predecessors for the purpose of adjusting net operating loss carryforwards to years for which the statute of limitations has not closed. We classify interest and penalties attributable to income taxes as part of income tax expense. As of June 30, 2019 and December 31, 2018, we had no recorded amounts for accrued interest or penalties. Because we do not permanently reinvest foreign earnings, United States deferred income taxes have been provided on unremitted foreign earnings to the extent that such foreign earnings are expected to be taxable upon repatriation. c. Long-Lived Assets We review long-lived assets, including finite-lived intangible assets subject to amortization, for impairment upon the occurrence of events or changes in circumstances that would indicate that the carrying value of the asset or group of assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparing the carrying amount of the asset or group of assets to the future net cash flows expected to be generated by the asset or group of assets. If such assets are not considered to be fully recoverable, any impairment to be recognized is measured by the amount by which the carrying amount of the asset or group of assets exceeds its respective fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. d. Earnings Per Common Share Basic earnings per common share is computed by dividing net income attributable to Holdings’ common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per common share is computed by dividing net income attributable to Holdings’ common stockholders by the weighted average number of common shares outstanding during the period, including the effect of all dilutive common stock equivalents using the treasury stock method. In periods for which there is a net loss, diluted loss per common share is equal to basic loss per common share, since the effect of including any common stock equivalents would be antidilutive. The computation of diluted earnings per common share included the effect of 580,000 and 1,406,000 dilutive stock options and restricted stock units and excluded the effect of 2,989,000 and 346,000 antidilutive stock options and restricted stock units for the three months ended June 30, 2019 and June 30, 2018, respectively. The computation of diluted earnings per share included the effect of 675,000 and 1,430,000 dilutive stock options and restricted stock units and excluded the effect of 2,872,000 and 193,000 antidilutive stock options and restricted stock units for the six months ended June 30, 2019 and June 30, 2018, respectively. Earnings per common share for the three and six months ended June 30, 2019 and June 30, 2018 was calculated as follows: Three Months Ended Six Months Ended (Amounts in thousands, except per share data) June 30, 2019 June 30, 2018 June 30, 2019 June 30, 2018 Net income attributable to Six Flags Entertainment Corporation $ 79,519 $ 74,502 $ 10,387 $ 12,157 Weighted-average common shares outstanding - basic: 84,288 83,666 84,207 84,059 Effect of dilutive stock options and restricted shares 580 1,406 675 1,430 Weighted-average common shares outstanding - diluted: 84,868 85,072 84,882 85,489 Earnings per share - basic: $ 0.94 $ 0.89 $ 0.12 $ 0.14 Earnings per share - diluted: $ 0.94 $ 0.88 $ 0.12 $ 0.14 e. Derivative Instruments and Hedging Activities We account for derivatives and hedging activities in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and our strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash flow hedges to forecasted transactions. We also assess, both at the hedge’s inception and on an ongoing basis throughout the contract term, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. Changes in the fair value of interest rate derivatives that are effective and that are designated and qualify as cash flow hedges are recorded in “Other comprehensive (income) loss” until operations are affected by the variability in cash flows of the designated hedged item, at which point they are reclassified to “interest expense”. Changes in the fair value of derivatives that do not qualify for hedge accounting or that are de-designated are recorded in other (income) expense, net in the unaudited condensed consolidated statements of operations. f. Fair Value of Financial Instruments The fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties. We use a market approach for our recurring fair value measurements, and we endeavor to use the best information available. Accordingly, valuation techniques that maximize the use of observable impacts are favored. We present the estimated fair values and classifications of our financial instruments in accordance with FASB ASC Topic 820, Fair Value Measurement. We use the following methods and assumptions to estimate the fair value of each class of financial instruments: ● The carrying values of cash and cash equivalents, accounts receivable, notes receivable, accounts payable and accrued liabilities approximate fair value because of the short maturity of these instruments. ● The measurement of the fair value of long-term debt is based on market prices that generally are observable for similar liabilities at commonly quoted intervals and is considered a Level 2 fair value measurement. See Note 3 for additional information. ● The measurement of the fair value of derivative assets and liabilities is based on market prices that generally are observable for similar assets and liabilities at commonly quoted intervals and is considered a Level 2 fair value measurement. Derivative assets and liabilities that have maturity dates equal to or less than twelve months from the balance sheet date are included in prepaid and other current assets and other accrued liabilities, respectively. Derivative assets and liabilities that have maturity dates greater than twelve months from the balance sheet date are included in deposits and other assets and other long-term liabilities, respectively. See Note 5 for additional information on our derivative instruments and related Company policies. g. Stock Benefit Plans Pursuant to the Six Flags Entertainment Corporation Long-Term Incentive Plan (the "Long-Term Incentive Plan"), Holdings may grant stock options, stock appreciation rights, restricted stock, restricted stock units, unrestricted stock, deferred stock units, performance and cash-settled awards and dividend equivalent rights ("DERs") to select employees, officers, directors and consultants of Holdings and its affiliates. We recognize the fair value of each grant as compensation expense on a straight-line basis over the vesting period using the graded vesting terms of the respective grant. The fair value of stock option grants is estimated using the Black-Scholes option pricing valuation model. The fair value of stock, restricted stock units and restricted stock awards is the quoted market price of Holdings’ common stock on the date of grant. During the three months and six months ended June 30, 2019 and June 30, 2018, stock-based compensation expense consisted of the following: Three Months Ended Six Months Ended (Amounts in thousands) June 30, 2019 June 30, 2018 June 30, 2019 June 30, 2018 Long-Term Incentive Plan Options and other $ 3,494 $ 3,803 $ 7,310 $ 7,269 Performance awards (1) — 12,129 — 13,141 Employee Stock Purchase Plan 59 104 134 179 Total Stock-Based Compensation $ 3,553 $ 16,036 $ 7,444 $ 20,589 (1) h. Revenue Recognition FASB ASC 606, Revenue from Contracts with Customers of the membership program. Guests enrolled in the membership program can visit our parks an unlimited number of times whenever the parks are open as long as the guest remains enrolled in the membership program. We review the estimated redemption rate regularly and on an ongoing basis and revise it as necessary throughout the year. Amounts owed or received for multi-use admissions in excess of redemptions are recognized in deferred revenue. For active memberships after the initial twelve-month term, we recognize revenue monthly as payments are received. As of June 30, 2019, deferred revenue was primarily comprised of (i) unredeemed season pass and all season dining pass revenue, (ii) pre-sold single-day admissions revenue for the current operating season, (iii) unredeemed portions of the membership program and member dining program that will primarily be recognized in 2019, and (iv) payments received from our international development partners in excess of revenue recognized. We have entered into international agreements to assist third parties in the planning, design, development and operation of Six Flags-branded parks outside of North America. These agreements typically consist of a brand licensing agreement, project services agreement, and management services agreement. Under Topic 606, we treat these agreements as one contract because they were negotiated with a single commercial objective. We have identified three distinct promises within the agreement with each third party partner as brand licensing, project services and management services. Each of these promises is its own performance obligation and distinct, as the third party could benefit from each service on its own with other readily available resources, and each service is separately identifiable from other services in the context of the contract. We recognize revenue under our international agreements over the relevant service period of each performance obligation based on its relative stand-alone selling price, as determined by our best estimate of selling price. We review the service period of each performance obligation on an ongoing basis and revise it as necessary throughout the year. Revisions to the relevant service periods of the performance obligations may result in revisions to revenue in future periods and are recognized in the period in which the change is identified. Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine standalone selling prices based on the observable prices charged to customers. We generally expense (i) sales commissions when incurred, and (ii) certain costs to obtain a contract where the amortization period would have been one year or less. These costs are recognized in "Selling, general and administrative expenses." We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less or (ii) contracts for which we recognize revenue at the amount for which we have the right to invoice for services performed. For certain of our contracts that have an original expected length of one year or less, we use the practical expedient applicable to such contracts and do not consider the time value of money. i. Leases We or certain of our subsidiaries are a lessee in various noncancellable operating leases, primarily for operating rights to amusement parks, land, office space, warehouses, office equipment and machinery. We account for leases in accordance with FASB ASC 842, Leases For our operating leases, the lease liability is initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date. Key estimates and judgments include how we determine (i) the discount rate used to discount the unpaid lease payments to present value, (ii) the lease term and (iii) the lease payments. Topic 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate ("IBR"). Generally, we cannot determine the interest rate implicit in the lease and therefore uses the IBR as a discount rate for our leases. The IBR reflects the rate of interest we would pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. The lease term for all of our leases includes the noncancellable period of the lease plus any additional periods covered by an option to extend the lease that are reasonably certain to be executed by us. Lease payments included in the measurement of the lease liability comprise fixed payments owed over the lease term, variable lease payments that depend on an index or rate, and the exercise price of an option to purchase the underlying asset if it is reasonably certain that we will exercise the option. The ROU asset is initially measured at cost, which comprises the initial amount of lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For our operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, and adjusted for any prepaid or accrued lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the term of the operating lease. Variable lease payments associated with our leases are recognized upon the occurrence of the event, activity, or circumstance in the lease agreement on which those payments are assessed. Variable lease payments for operating leases are presented as operating expense in our condensed consolidated statements of operations in the same line item as expense arising from fixed lease payments. Operating lease ROU assets net of accumulated amortization are presented as "Right-of-use operating leases, net" on the condensed consolidated balance sheets. The current portion of operating lease liabilities is presented as "Short-term operating lease liabilities" and the long-term portion is presented separately as "Long-term operating lease liabilities" on the condensed consolidated balance sheets. We have elected not to recognize ROU assets and lease liabilities for short-term leases that have a lease term of 12 months or less. We recognize the lease payments associated with short-term leases as an expense on a straight-line basis over the lease term. Variable lease payments associated with short-term leases are recognized and presented in the same manner as for all other leases. The ROU assets for operating leases may be periodically reduced by impairment losses. We use the long-lived assets impairment guidance in ASC Subtopic 360-10, Property, Plant and Equipment - Overall j. Accounts Receivable, Net Accounts receivable are reported at net realizable value and consist primarily of amounts due from guests for the sale of group outings and multi-use admission products, such as season passes and the membership program. We are not exposed to a significant concentration of credit risk; however, based on the age of the receivables, our historical experience and other factors and assumptions we believe to be customary and reasonable, we record an allowance for doubtful accounts. As of June 30, 2019 and December 31, 2018, we have recorded an allowance for doubtful accounts of $25.4 million and $7.4 million, respectively, which is primarily comprised of estimated payment defaults under our membership program. To the extent that payment under our membership program have not been recognized in revenue, the allowance for doubtful accounts recorded against our membership program is offset with a corresponding reduction in deferred revenue. k. Recently Adopted Accounting Pronouncements On January 1, 2019, we adopted Topic 842 using the modified retrospective transition method applied to leases with terms extending past January 1, 2019 Topic 842 requires recognition on the balance sheet of lease ROU assets and lease liabilities by lessees for those leases classified as operating leases in order to give more transparency on commitments and future cash flow. The new guidance is effective for annual periods beginning after December 15, 2018, including interim periods within the fiscal year. The new standard supersedes the previous lease accounting standard under FASB ASC 840, Leases l.
