S UMMARY OF IGNIFICANT CCOUNTING OLICIES Use of Estimates Cash and Cash Equivalents Cash and cash equivalents held in interest-bearing accounts may exceed the Federal Deposit Insurance Corporation insurance limits. To reduce credit risk, the Company monitors the credit standing of the financial institutions that hold the Company’s cash and cash equivalents. However, balances could be impacted in the future if underlying financial institutions fail. As of December 31, 2019 and 2020, the Company has not experienced any loss or lack of access to its cash and cash equivalents. Accounts Receivable and Credit Policies Due to the significant COVID-19 COVID-19 Inventory Property and Equipment — Asset Class Useful Life Computer Equipment 5 years Purchased Software 3 years Furniture and Fixtures 7 years Leasehold improvements are amortized over the shorter of the term of the lease or the improvements’ estimated useful lives. Personal Seat Licenses Impairments Long-Lived Assets Impairment Assessments require a long-lived asset or asset group to be held and used be tested for possible impairment, we first compare the undiscounted cash flows expected to be generated by that long-lived asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent the carrying amount exceeds its fair value. During the second quarter of 2020, we determined a triggering event occurred that required us to evaluate our long-lived assets for impairment. We recorded an impairment charge as a result of those assessments. Refer to Note 8, Impairments Goodwill and Intangible Assets non-compete We evaluate goodwill and our indefinite-lived intangible asset for impairment annually on October 31 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable. We have the option to assess goodwill and our indefinite-lived intangible asset for impairment by first performing a qualitative assessment to determine whether it is more-likely-than-not more-likely-than-not The fair value of our definite-lived intangible assets is determined using both the market approach and income approach, utilizing Level 3 inputs. We review our definite-lived intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset or asset group may not be recoverable. If circumstances require a definite-lived intangible asset or its asset group to be held and used be tested for possible impairment, we first compare the undiscounted cash flows expected to be generated by that definite-lived intangible asset or asset group to its carrying amount. If the carrying amount of the definite-lived intangible asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its fair value. Definite-lived intangible assets are amortized on a straight-line basis over their estimated period of benefit, over the following estimated useful lives: Asset Class Useful Life Non-competition 3 years Supplier relationships 4 years Developed technology 3-5 years Customer relationships 3-5 The useful lives of definite-lived intangible assets are re-assessed During the second quarter of 2020, we determined a triggering event occurred that required us to evaluate our goodwill, indefinite-lived intangible asset, and definite-lived intangible assets for impairment, and we recorded an impairment charge as a result of those assessments. Refer to Note 8, Impairments Business Combinations Acquisition. Internal-use internal-use Accrued Customer Credits Accrued Future Customer Compensation Taxes The Company is subject to partnership audit rules enacted as part of the Bipartisan Budget Act of 2015 (the “Centralized Partnership Audit Regime”). Under the Centralized Partnership Audit Regime, any IRS audit of the Company would be conducted at the Company level, and if the IRS determines an adjustment, the default rule is that the Company would pay an “imputed underpayment” including interest and penalties, if applicable. The Company may instead elect to make a “push-out” The Hoya Intermediate, LLC Agreement stipulates that, if the Company receives an imputed underpayment, each Unit holder shall promptly file an amended tax return and pay any tax and interest due. As of December 31, 2019 and 2020, there were no uncertain tax positions taken or expected to be taken that would require recognition of a liability in the consolidated financial statements. The Company is subject to routine audits by taxing jurisdictions. The periods subject to tax audits are 2017 through 2020. There are currently no audits for any tax periods in progress. Debt Derivatives — Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of the gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company formally evaluates, both at the inception of the hedge and quarterly, whether the derivative financial instrument is highly effective in offsetting changes in cash flows of the related underlying exposure. For derivatives that are designated as, and meet all the required criteria for, a cash flow hedge, the net interest payments are recorded in Interest expense — net in the Consolidated Statements of Operations and Comprehensive Loss and the remaining changes in the fair value are recorded in Accumulated other comprehensive loss (“AOCL”) in the Consolidated Balance Sheets and reclassified into earnings as the underlying hedged item affects earnings. Derivative instruments are classified within Prepaid expenses and other current assets or Other liabilities in the Consolidated Balance Sheets depending on the nature of the balance at the end of the period. Fair Value of Financial Instruments Level 1 Level 2 Level 3 Equity-Based Compensation Compensation–Stock Compensation Distinguishing Liabilities from Equity Equity-based compensation is measured at fair value on the grant date. The Company recognizes compensation expense on a straight-line basis over the requisite service period, which is the award’s vesting period, and an offsetting deemed contribution to equity to reflect these incentive units of our parent. Vesting of these awards is accelerated in the event of a change in control of Hoya Topco, LLC. The Company accounts for forfeitures as they occur. A market-based approach was used to determine the total equity value of our parent and allocate the resulting value between classes using an option pricing model to determine the grant date fair value of employee grants. The exercise prices used are based on various scenarios considering the waterfall payout structure of the units that exists at the Hoya Topco, LLC level. For liability-based compensation with service and performance conditions, the Company recognizes a liability for the fair value of the outstanding units only when the Company concludes it is probable that the performance condition will be achieved. As of December 31, 2019 and 2020, it is not probable the performance condition will be achieved. Net Loss Per Unit Attributable to Common Unit holders Segment Reporting — Revenue Recognition Revenue from Contracts with Customers The Company reports revenue on a gross or net basis based on management’s assessment of the Company acting as a principal or agent in the transaction. The determination of the Company acting as a principal or an agent in a transaction is based on the evaluation of control over the ticket, including the right to sell the ticket, before it is transferred to the ticket buyer. Marketplace The Company acts as an intermediary between ticket sellers and ticket buyers in its secondary marketplace. Revenue primarily consists of service fees from ticketing operations and is reduced by incentives provided to ticket buyers. The Company has one primary performance obligation, facilitating the Marketplace transaction between the ticket seller and ticket buyer, which is satisfied at the time the order is confirmed. In this transaction, the Company acts as an agent as it does not control the ticket prior to it transferring to the ticket buyer. Revenue is recognized net of the amount due to the seller when the ticket seller confirms an order with the ticket buyer, at which point the seller is obligated to deliver the tickets to the buyer in accordance with the original marketplace listing. Payment from the buyer is due at the time of sale. The Company’s sales terms provide that the Company will compensate the buyer for the total amount of the purchase if an event is cancelled, the ticket is invalid, or if the ticket is delivered after the promised time. The Company has determined this is considered a stand-ready obligation to provide a return that is not a separate performance obligation, but is an element of variable consideration, which results in a reduction to revenue. The revenue reversal is reflected within Accrued expenses and other current liabilities in the Consolidated Balance Sheets when the buyer has yet to be compensated. The Company estimates the customer compensation liability, and corresponding charge against revenue, using the expected value method, which best predicts customer compensation for future cancellations. To the extent we estimate that a portion of the refund is recoverable from the ticket seller, we record the recovery as revenue to align with the net presentation of the original transaction. The timing of event cancellations and rescheduling of postponed events versus new sales transactions can result in customer compensation costs exceeding current period sales resulting in negative marketplace revenue for that period. The Company also earns referral commissions on purchases of third-party insurance services by ticket buyers at the time of sale of the associated ticket on the Marketplace platform. Referral commissions are recognized as revenue when the ticket buyer makes a purchase from the third-party merchant during customer checkout. Payment from the third-party provider is due to the Company net 30 from when invoiced. This revenue is included within all categories of Marketplace disaggregated revenue described in Note 3, Revenue Recognition. Resale The Company sells tickets it owns on secondary ticket marketplaces. The Resale business has one performance obligation, which is to transfer control of a live event ticket to a ticket buyer once an order has been confirmed. The Company acts as a principal in these transactions as it owns the ticket and therefore controls the ticket prior to transferring the ticket to the customer. Revenue is recorded on a gross basis based on the value of the ticket and is recognized when an order is confirmed in the secondary ticket marketplace. Payment from the marketplace is typically due upon delivery of the ticket or after the event has passed. Secondary marketplace terms and conditions require sellers to repay amounts received for events that are cancelled or tickets that are invalid or delivered after the promised time. The Company has determined that this obligation is a stand-ready obligation to provide a return that is not a separate performance obligation, but is an element of variable consideration, which results in a reduction to revenue. The Company recognizes a liability for known and estimated cancellation charges within Accrued expenses and other current liabilities in the Consolidated Balance Sheets. The Company estimates the future customer compensation liability, and corresponding charge against revenue, using the expected value method. To the extent we estimate that a portion of the charge is recoverable from the event host, we record the estimated recovery asset to Prepaid expenses and other current assets. When the Company’s Resale business sells a ticket on its own marketplace, the service fee is recorded in Marketplace revenues and the sales price of the ticket is recorded in Resale revenues. Deferred Revenue Deferred revenue consists of fees received related to unsatisfied performance obligations at the end of the period. Due to the generally short-term duration of contracts, the majority of the performance obligations are satisfied in the following year. The Company’s loyalty program allows customers to earn credits on certain purchases and then redeem those credits on future transactions. The credits earned in the program represent a material right to the customer and constitute an additional performance obligation of the Company. As such, the Company defers revenue based on expected future usage and recognizes the deferred revenue as credits are redeemed. Breakage income from credits that are not expected to be used is estimated and recognized as revenue in proportion to the pattern of redemption for the customer credits that are used. Cash received for contingent events, such as postseason sporting events, is initially recorded as Deferred revenue in the Consolidated Balance Sheets and is recognized as revenue when the contingency is resolved. Advertising Costs e-mail Shipping and Handling Immaterial Correction of an Error in Prior Periods Accounting Changes and Error Corrections The Company has adjusted for these errors by revising its financial statements presented herein. The correction resulted in an increase to Cost of revenues of $2,669 thousand and $1,753 thousand for the years ended December 31, 2019 and 2020, respectively, with corresponding reductions to General and administrative expenses. The increase to Cost of revenues resulted in a decrease to Marketplace and Resale contribution margin of $2,324 thousand and $345 thousand, respectively, for the year ended December 31, 2019, and a decrease to Marketplace and Resale contribution margin of $1,468 thousand and $285 thousand, respectively, for the year ended December 31, 2020.

I MPAIRMENTS As disclosed in Note 2, Significant Accounting Policies During the second quarter of 2020, the Company identified the COVID-19 COVID-19 The following summarizes the impairment charges recorded by the Company during the second quarter of 2020 (in thousands): Goodwill $ 377,101 Indefinite lived trademark 78,734 Definite lived intangible assets 107,365 Property and equipment 3,670 Personal seat licenses 6,968 Total impairment charges $ 573,838 Long-lived asset impairments The Company assessed its long-lived assets for potential impairment during the second quarter of 2020. ASC 360, Property, Plant, and Equipment right-of-use For the fair value of the asset group, we compared the expected future undiscounted cash flows associated with the asset group to the long-lived asset group’s carrying value and concluded that the carrying value was not recoverable. The Company then measured the fair value of the asset group using a discounted cash flow model. The significant estimates used in the undiscounted and discounted cash flow models include projected operating cash flows; forecasted capital expenditures and working capital needs; rates of long-term growth; and the discount rate (in the discounted cash flow model). The significant unobservable inputs included forecasted revenues which reflected significant declines in earlier years as a result of the pandemic and included estimates regarding when revenue would return to pre-pandemic pre-pandemic Fair Value, Indefinite-lived trademark and goodwill impairments During the second quarter of 2020, the Company determined that the estimated carrying value of its indefinite-lived trademark was in excess of its fair value. The fair value of the indefinite-lived trademark asset, classified as a Level 3 measurement, was measured using the relief-from-royalty method. This methodology involves estimating reasonable royalty rates for the trademarks, applying the royalty rate to a net sales stream, and utilizing the discounted cash flow method. The Company utilized a 2.0% royalty rate, consistent with the rate used in the initial valuation of the trademark. The Company recorded an impairment charge of $78,734 thousand related to the indefinite-lived trademark. The impairment charge is presented in Impairment charges in the Consolidated Statements of Operations and Comprehensive Loss. As part of the goodwill impairment assessment performed during the second quarter of 2020, the Company determined that the carrying value of its Marketplace reporting unit exceeded its estimated fair value, resulting in a goodwill impairment charge of $377,101 thousand, which is presented in Impairment charges in the Consolidated Statements of Operations and Comprehensive Loss. The fair value estimate of our reporting units was based on a blended analysis of the present value of future discounted cash flows and market value approach, using Level 3 inputs. The significant estimates used in the discounted cash flow models are projected operating cash flows; forecasted capital expenditures and working capital needs; weighted average cost of capital; and rates of long-term growth. These estimates considered the recent deterioration in financial performance of the reporting units, as well as the anticipated rate of recovery, and implied risk premiums based on the market prices of our equity and debt as of the assessment date. The significant estimates used in the market multiple valuation approach include identifying business factors; such as size, growth, profitability, risk and return on investment; and assessing comparable revenue and earnings multiples. Following the impairment charge, the carrying value of the Marketplace reporting unit’s goodwill was $683,327 thousand. In accordance with its annual re-assessment, The Company’s goodwill and indefinite-lived trademark constitute nonfinancial assets measured at fair value on a nonrecurring basis. These nonfinancial assets are classified as Level 3 assets in the fair value hierarchy established under ASC Topic 820, Fair Value Measurement

The Company estimated the expected term of the incentive units considering the timing and probabilities of a liquidity event. The risk-free interest rate for the expected term of the incentive units is based on the U.S. Treasury yield curve, with maturities similar to the expected term of the incentive units, in effect at the time of grant. The Company also estimated the number of units expected to be granted as it represents an input in the determination of compensation expense. For the year ended December 31, 2019, the Company estimated that one million Class D Units and 500,765 Class E Units would be granted, as applicable.

If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent the carrying amount exceeds its fair value.

We have the option to assess goodwill and our indefinite-lived intangible asset for impairment by first performing a qualitative assessment to determine whether it is more-likely-than-not more-likely-than-not The fair value of our definite-lived intangible assets is determined using both the market approach and income approach, utilizing Level 3 inputs. We review our definite-lived intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset or asset group may not be recoverable. If circumstances require a definite-lived intangible asset or its asset group to be held and used be tested for possible impairment, we first compare the undiscounted cash flows expected to be generated by that definite-lived intangible asset or asset group to its carrying amount.

Derivatives		Derivatives — Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of the gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company formally evaluates, both at the inception of the hedge and quarterly, whether the derivative financial instrument is highly effective in offsetting changes in cash flows of the related underlying exposure. For derivatives that are designated as, and meet all the required criteria for, a cash flow hedge, the net interest payments are recorded in Interest expense — net in the Consolidated Statements of Operations and Comprehensive Loss and the remaining changes in the fair value are recorded in Accumulated other comprehensive loss (“AOCL”) in the Consolidated Balance Sheets and reclassified into earnings as the underlying hedged item affects earnings. Derivative instruments are classified within Prepaid expenses and other current assets or Other liabilities in the Consolidated Balance Sheets depending on the nature of the balance at the end of the period.

The Company recognizes compensation expense on a straight-line basis over the requisite service period, which is the award’s vesting period, and an offsetting deemed contribution to equity to reflect these incentive units of our parent. Vesting of these awards is accelerated in the event of a change in control of Hoya Topco, LLC. The Company accounts for forfeitures as they occur. A market-based approach was used to determine the total equity value of our parent and allocate the resulting value between classes using an option pricing model to determine the grant date fair value of employee grants. The exercise prices used are based on various scenarios considering the waterfall payout structure of the units that exists at the Hoya Topco, LLC level. For liability-based compensation with service and performance conditions, the Company recognizes a liability for the fair value of the outstanding units only when the Company concludes it is probable that the performance condition will be achieved. As of December 31, 2019 and 2020, it is not probable the performance condition will be achieved.

Revenue Recognition		Revenue Recognition Revenue from Contracts with Customers The Company reports revenue on a gross or net basis based on management’s assessment of the Company acting as a principal or agent in the transaction. The determination of the Company acting as a principal or an agent in a transaction is based on the evaluation of control over the ticket, including the right to sell the ticket, before it is transferred to the ticket buyer. Marketplace The Company acts as an intermediary between ticket sellers and ticket buyers in its secondary marketplace. Revenue primarily consists of service fees from ticketing operations and is reduced by incentives provided to ticket buyers. The Company has one primary performance obligation, facilitating the Marketplace transaction between the ticket seller and ticket buyer, which is satisfied at the time the order is confirmed. In this transaction, the Company acts as an agent as it does not control the ticket prior to it transferring to the ticket buyer. Revenue is recognized net of the amount due to the seller when the ticket seller confirms an order with the ticket buyer, at which point the seller is obligated to deliver the tickets to the buyer in accordance with the original marketplace listing. Payment from the buyer is due at the time of sale. The Company’s sales terms provide that the Company will compensate the buyer for the total amount of the purchase if an event is cancelled, the ticket is invalid, or if the ticket is delivered after the promised time. The Company has determined this is considered a stand-ready obligation to provide a return that is not a separate performance obligation, but is an element of variable consideration, which results in a reduction to revenue. The revenue reversal is reflected within Accrued expenses and other current liabilities in the Consolidated Balance Sheets when the buyer has yet to be compensated. The Company estimates the customer compensation liability, and corresponding charge against revenue, using the expected value method, which best predicts customer compensation for future cancellations. To the extent we estimate that a portion of the refund is recoverable from the ticket seller, we record the recovery as revenue to align with the net presentation of the original transaction. The timing of event cancellations and rescheduling of postponed events versus new sales transactions can result in customer compensation costs exceeding current period sales resulting in negative marketplace revenue for that period. The Company also earns referral commissions on purchases of third-party insurance services by ticket buyers at the time of sale of the associated ticket on the Marketplace platform. Referral commissions are recognized as revenue when the ticket buyer makes a purchase from the third-party merchant during customer checkout. Payment from the third-party provider is due to the Company net 30 from when invoiced. This revenue is included within all categories of Marketplace disaggregated revenue described in Note 3, Revenue Recognition. Resale The Company sells tickets it owns on secondary ticket marketplaces. The Resale business has one performance obligation, which is to transfer control of a live event ticket to a ticket buyer once an order has been confirmed. The Company acts as a principal in these transactions as it owns the ticket and therefore controls the ticket prior to transferring the ticket to the customer. Revenue is recorded on a gross basis based on the value of the ticket and is recognized when an order is confirmed in the secondary ticket marketplace. Payment from the marketplace is typically due upon delivery of the ticket or after the event has passed. Secondary marketplace terms and conditions require sellers to repay amounts received for events that are cancelled or tickets that are invalid or delivered after the promised time. The Company has determined that this obligation is a stand-ready obligation to provide a return that is not a separate performance obligation, but is an element of variable consideration, which results in a reduction to revenue. The Company recognizes a liability for known and estimated cancellation charges within Accrued expenses and other current liabilities in the Consolidated Balance Sheets. The Company estimates the future customer compensation liability, and corresponding charge against revenue, using the expected value method. To the extent we estimate that a portion of the charge is recoverable from the event host, we record the estimated recovery asset to Prepaid expenses and other current assets. When the Company’s Resale business sells a ticket on its own marketplace, the service fee is recorded in Marketplace revenues and the sales price of the ticket is recorded in Resale revenues. Deferred Revenue Deferred revenue consists of fees received related to unsatisfied performance obligations at the end of the period. Due to the generally short-term duration of contracts, the majority of the performance obligations are satisfied in the following year. The Company’s loyalty program allows customers to earn credits on certain purchases and then redeem those credits on future transactions. The credits earned in the program represent a material right to the customer and constitute an additional performance obligation of the Company. As such, the Company defers revenue based on expected future usage and recognizes the deferred revenue as credits are redeemed. Breakage income from credits that are not expected to be used is estimated and recognized as revenue in proportion to the pattern of redemption for the customer credits that are used. Cash received for contingent events, such as postseason sporting events, is initially recorded as Deferred revenue in the Consolidated Balance Sheets and is recognized as revenue when the contingency is resolved.
