Basis Of Presentation And Summary Of Significant Accounting Policies

Accounting Policies [Abstract]

Basis of presentation and summary of significant accounting policies

2. Basis of presentation and summary of significant accounting policies

This summary of significant accounting policies is presented to assist in understanding the Company’s condensed consolidated financial statements. These accounting policies have been consistently applied in the preparation of the condensed consolidated financial statements.

(a) Basis of presentation

The Company’s condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and reflect the financial position, results of operations and cash flows for all periods presented. The

year-end

condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP.

The accompanying interim condensed consolidated balance sheet as of June 30, 2021, the condensed consolidated statements of operations and comprehensive loss, of cash flows and of members’/stockholders’ equity for the three and six months ended June 30, 2021 and 2020, and the related footnote disclosures are unaudited. These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and, in management’s opinion, include all adjustments necessary to state fairly the consolidated financial position of the Company. All adjustments made were of a normal recurring nature. The results for the three months and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the year ending December 31, 2021 or for any future period.

The Company’s significant accounting policies are discussed in Note 2 to the consolidated financial statements for the years ended December 31, 2020 and 2019. There have been no significant changes to these policies that have had a material impact on the Company’s condensed consolidated financial statements and related notes for the three and six months ended June 30, 2021. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with our final IPO prospectus filed with the Securities and Exchange

Commission (“SEC”) on July 1, 2021.

(b) Basis of consolidation

The condensed consolidated financial statements include the accounts of Integral Ad Science Holding Corp. and its wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation.

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Significant estimates include the allocation of purchase price consideration in the business combination and the related valuation of acquired assets and liabilities, the estimated useful lives of our property and equipment, intangible assets and internal use software, the allowance for doubtful accounts, and goodwill impairment testing; the assumptions used to calculate stock-based compensation; and the realization of deferred tax assets. The Company bases its estimates on past experience, market conditions, and other assumptions that the Company believes are reasonable under the circumstances, and the Company evaluates these estimates on an ongoing basis.

Beginning in the first quarter of 2020, the

COVID-19

pandemic has negatively impacted, and may continue to negatively impact, the macroeconomic environment in the United States and globally, as well as the Company’s business, financial condition and results of operations. In the quarters subsequent to the second quarter of 2020, the underlying demand for the Company’s services has stabilized. Due to the evolving and uncertain nature of

COVID-19,

it is reasonably possible that it could materially impact the Company’s estimates, particularly those noted above that require consideration of forecasted financial information, in the near to medium term. The ultimate impact will depend on numerous evolving factors that the Company may not be able to accurately predict, including the duration of the pandemic, new variants and their effects, vaccination rates, the impact of federal, state, local and foreign governmental actions, consumer behavior in response to the pandemic and other economic and operational conditions the Company may face.

(d) Cash, cash equivalents, and restricted cash

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the condensed consolidated balance sheets to the amounts shown in the condensed consolidated statements of cash flows.


	June 30, 2021		December 31. 2020
Cash and cash equivalents	$	73,234	$	51,734
Short term restricted cash		75		187
Long term restricted cash (held in other long-term assets)		2,704		2,800

Total cash, cash equivalents, and restricted cash shown in the condensed consolidated statements of cash flows	$	76,013	$	54,721

(e) Accounts receivable, net

Accounts receivable are carried at the original invoiced amount less an allowance for doubtful accounts. The allowance is estimated based on management’s knowledge of its customers’ financial condition, credit history, and existing economic conditions. Invoices are typically issued with net

30-days

to net

90-days

terms. Account balances are considered delinquent if payment is not received by the due date, and the receivables are written off when deemed uncollectible. These costs are recorded in general and administrative expenses.

The activity in our allowance for doubtful accounts consists of the following as of:


	June 30, 2021			June 30, 2020
Balance, beginning of period	$	4,257			5,843
Additional provision		99			1,170
Receivables written off		(558	)		(729	)

Balance, end of period	$	3,798			6,284

(f) Stock-based compensation

Stock-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which is generally the vesting period. The Company accounts for forfeitures as they occur. The Company used the following assumptions in valuing its time-based service options, which vest over a period of time subject to continued employment (“Time-Based Options”) and return target options (“Return-Target Options”), which vest upon a realized cash return of the equity investment of Vista Equity Partners, the Company’s equity sponsor and funds controlled by Vista Equity Partners (together, (“Vista”):

Expected term

— For time-based awards, the estimated expected term of options granted is generally calculated as the vesting period plus the midpoint of the remaining contractual term, as the Company does not have sufficient historical information to develop reasonable expectations surrounding future exercise patterns and post-vesting employment termination behavior. For awards subject to market and performance conditions, the expected term represents the period of time that the options granted are expected to be outstanding.

Expected volatility

— Since the Company does not have substantive trading history of its common stock, volatility is estimated based upon observed option-implied volatilities for a group of peer companies. The Company believes this is the best estimate of the expected volatility over the weighted-average expected term of its option grants.

Risk-free interest rate

— The risk-free interest rate is based on the implied yield currently available on U.S. Treasury instruments with terms approximately equal to the expected term of the option.

Expected dividend

— The expected dividend assumption was based on the Company’s history and expectation of dividend payouts. The Company currently has no history or expectation of paying cash dividends on its units.

Fair value

—Prior to the IPO, because there was no public market for the Company’s common stock/units, the board of directors determined the best estimate of the fair value of the Company’s option grants, based on reasonable judgment and numerous objective and subjective factors, including independent third-party valuations of the Company’s common stock/units, operating and financial performance, and general and industry-specific economic outlook, amongst other factors. Following the pricing of the IPO, the Company’s shares are traded in the public market, and accordingly the Company uses the applicable closing price of its common stock to determine fair value.

The Company used the following assumptions in valuing its stock-based compensation:


	June 30, 2021	June 30, 2020 (1)
Estimated fair value	$7.77 –13.93	$2.29
Expected volatility (%)	65.0 –80.0%	70.0-75.0%
Expected term (in years)	3-10	3.25-6.63
Risk-free interest rate (%)	0.41 –0.98%	0.26-0.55%
Dividend yield	—	—

(1)

For issuances prior to the pricing of the IPO, the fair value of the Company’s option grants was estimated at the grant date using the Monte Carlo simulation model and relate to the Return-Target Options only as the Time-Based Options were not within the scope of ASC 718,

Compensation -

Stock Compensation

for the three and six months ended June 30, 2020.

(g) Deferred offering costs

Deferred offering costs are capitalized and consist of fees incurred in connection with our IPO and include legal, accounting, printing, and

other IPO-related costs.

Upon the completion of our IPO, which occurred on July 2, 2021, these deferred costs will be reclassified to members’/stockholders’ equity and recorded against the proceeds from the offering.

Deferred offering costs of $6,361 are included within prepaid expenses and other current assets as of June 30, 2021. No such costs were incurred as of December 31, 2020.

(h) Recently adopted accounting pronouncements

In January 2017, the Financial Accounting Standards Board (the “FASB”) issued ASU

No. 2019-12,

Income

Taxes

(Topic

740):

Simplifying

the

Accounting

for Income Taxes

(“ASU

No. 2019-12”)

effective January 1, 2021, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740,

Income

Taxes

, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. Most amendments within ASU

No. 2019-12

are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. The Company early adopted ASU

No. 2019-12,

which did not have a material impact on the Company’s condensed consolidated financial statements.

In August 2018, the FASB issued ASU

2018-15,

Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract

(“ASU

No. 2018-15”),

which requires customers in a cloud computing arrangement that is a service contract to follow the internal use software guidance in ASC

350-40

to determine which implementation costs to capitalize as assets. The guidance requires certain costs incurred during the application development stage to be capitalized and other costs incurred during the preliminary project and post-implementation stages to be expensed as they are incurred. Capitalized implementation costs related to a hosting arrangement that is a service contract will be amortized over the term of the hosting arrangement, beginning when the module or component of the hosting arrange is ready for its intended use. A customer’s accounting for the hosting component of the arrangement is not affected. The Company adopted this guidance on January 1, 2021 on a prospective basis. The adoption of ASU

2018-15

did not have a material impact on the Company’s condensed consolidated financial statements.

(

i) Accounting pronouncements not yet adopted

In March 2020, the FASB issued ASU

2020-04,

“

Facilitation of the Effects of Reference Rate Reform on Financial Reporting

,” which intends to address accounting consequences that could result from the global markets’ anticipated transition away from the use of the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. The amendments in this ASU provide operational expedients and exceptions for applying U. S GAAP to contracts, hedging relationships and other transactions to affected by reference rate reform if certain criteria are met. The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of the reference rate reform. The optional amendments are effective for all entities as of March 12, 2020, through December 31, 2022. The Company intends to elect to apply certain of the optional expedients when evaluating the impact of reference rate reform on its debt instruments that reference LIBOR.

In June 2016, the FASB issued ASU No.

2016-13, “

Financial Instruments-Credit Losses (Topic 326)

Measurement of Credit Losses on Financial Instruments,”

which is intended to provide more decision-useful information about expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. ASU

2016-13

revises the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in more timely recognition of losses on financial instruments, including, but not limited to accounts receivable. This guidance will be effective for the Company beginning January 1, 2023, including interim periods within that reporting period. Early adoption is permitted and the update allows for a modified retrospective method of adoption. The Company is currently evaluating the potential effect that adopting this guidance will have on its Condensed Consolidated Financial Statements.

In February 2016, the FASB issued ASU

2016-02,

“

Leases (Topic 842)

”. Under the new guidance, lessees will be required to put most leases on their balance sheets but to recognize expenses in the income statement in a manner similar to current accounting. The guidance also eliminated the current real estate-specific provisions and changes the guidance on sale-leaseback transactions, initial direct costs, and lease executory costs for all entities. The updated guidance will be effective for the Company beginning January 1, 2022, with early adoption permitted. Upon adoption, entities will be required to use the modified retrospective approach for leases that exist, or are entered into, after the beginning of the earliest comparative period in the financial statements. In July 2018, the FASB issued ASU

2018-11,

Leases (Topic 842),

Targeted Improvements

, which allows entities to not apply the new leases standard, including its disclosure requirements, in the comparative periods they present in their financial statements in the year of adoption. The Company is currently evaluating the potential effect that adopting this guidance will have on its condensed consolidated financial statements.

Credit Agreement

On July 19, 2018, the Company entered into a credit agreement with various lenders (“Credit Agreement”), providing a term facility in the aggregate principal amount of $325,000 (“Term Loan”) and the ability to draw additional funds through a revolving facility (“Revolving Loan”) of up to $25,000. The Term Loan and Revolving Loan have a maturity date of July 19, 2024 and July 19, 2023, respectively.

In addition to interest payable in cash, the Credit Agreement includes Paid in Kind (“PIK”) interest at a rate

of 1.25% per annum. All PIK interest due is paid by capitalizing such interest and adding such applicable PIK interest to the principal amount of the outstanding Term Loan. The interest rate for the

cash interest under the

Credit Agreement may be either the (a) Alternate Base Rate, which is equal to the greatest of the base rate in effect, the Federal Funds Rate in effect on such day plus 0.5% and one month adjusted LIBOR plus 1.0%, plus an applicable margin of 5% or for eurodollar borrowings, the (b) Eurodollar rate, which is the adjusted LIBOR plus an applicable margin of 6%. The Company has elected the Eurodollar rate through 2020. The interest rate as of June 30, 2021 was 6.0%.

On November 19, 2019, the Company entered into an incremental facility assumption amendment (“Incremental Term Loan”) to the Credit Agreement which increased the aggregate principal amount by $20,000 used to finance the ADmantX S.p.A acquisition, pay fees, costs, and expenses incurred in connection with the agreement, and finance working capital and general corporate purposes. All terms and conditions of the Term Loan remained consistent under the Incremental Term Loan. In connection with

the entry into

the Credit Agreement, the Company incurred debt issuance costs of $7,476. In connection with

Incremental Term Loan, the Company incurred debt issuance costs of $473. Debt issuance costs related to the Term Loan and Incremental Term Loan were recorded as a deferred charge and direct offset to long-term debt and are amortized into interest expense over the contractual term of the borrowings using the straight-line method. As no amounts were drawn on the Revolving Loan as of June 30, 2021, the debt issuance costs related to this facility were recorded as a deferred financing asset within prepaid expenses and other current assets and are amortized into interest expense over the contractual term of the borrowings using the straight-line method.

All of the obligations under the Credit Agreement are guaranteed by the Company and its subsidiaries other than certain excluded subsidiaries. The Credit Agreement contains covenants requiring certain financial information to be submitted monthly, quarterly and annually

The Company must maintain a minimum liquidity level, as defined, and comply with a Revenue Leverage Ratio based on the last twelve months (“LTM”) which was required to be 1:50:1.00 or lower for the second quarter of 2021. The benchmark for the Revenue Leverage Ratio decreases through the term of the loan. The Credit Agreement also places restrictions on the incurrence of additional indebtedness, the payment of dividends, sale of assets, and entering into any merger or acqu

isition. As of June 30, 2021, the Company was in compliance with all covenants contained in the Credit Agreement.

The carrying amount of the Term Loan is as follows:


	June 30, 2021			December 31, 2020
Term Loan	$	345,000		$	345,000
PIK Interest		10,934			10,539
Less: Unamortized debt issuance costs		(3,839	)		(4,468	)

Total carrying amount of Term Loan	$	352,095		$	351,071

Amortization expense related to debt issuance costs for the three months ended June 30, 2021 and 2020 was $341 and $341, respectively. Amortization expense related to debt issuance costs for the six months ended June 30, 2021 and 2020 was $683 and $683, respectively.

The Company recognized interest expense of $4,825 and $6,231 during the three month periods ended June 30, 2021 and 2020, respectively. The Company recognized interest expense of $11,047 and $13,052 for the six month period ended June 30, 2021 and 2020, respectively.

Future principal payments of long-term debt as of June 30, 2021, without including additional PIK interest, are as follows:

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2021
Income Tax Disclosure [Abstract]
Income taxes	9. Income taxes At the end of each interim period, the Company estimates the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to significant, unusual, or extraordinary items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which they occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or unrecognized tax benefits is recognized in the interim period in which the change occurs. The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in foreign jurisdictions, permanent and temporary differences, and the likelihood of the realization of deferred tax assets generated in the current year. The accounting estimates used to compute the provision or benefit for income taxes may change as new events occur, more experience is acquired, additional information is obtained or the Company’s tax environment changes. To the extent that the expected annual effective income tax rate changes during a quarter, the effect of the change on prior quarters is included in income tax provision in the quarter in which the change occurs. For the three months ended June 30, 2021 and 2020, the Company recorded an income tax benefit of $3,045 and $5,519, respectively, due primarily to pre-tax book losses offset by non-deductible stock-based compensation. The Company’s effective tax rate for the period ending June 30, 2021 was 9.5%. The Company’s effective tax rate is lower than the statutory rate primarily due to non-deductible stock-based compensation as the Company is now subject to the provisions of IRC 162(m) as a result of becoming a public company on June 30, 2021. For the six months ended June 30, 2021 and 2020, the Company recorded an income tax benefit of $3,958 and $9,130, respectively, due primarily to pre-tax book losses. The Company’s effective tax rate for the period ending June 30, 2020 was 23.0%. The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. The Company is not currently under audit in any taxing jurisdiction. As of June 30, 2021 the Company does not have an accrual relating to uncertain tax positions.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Integral Ad Science Holding Corp. 2018 Stock Option Plan

On August 1, 2018, the Company adopted the 2018

Non-Qualified

Stock Option Plan (“2018 Plan”). Under the 2018 Plan, the Company had issued (i) Time-Based Options that vest over four years with 25% vesting after twelve months and an additional 6.25% vesting at the end of each successive quarter thereafter; and (ii) Return-Target Options that vest upon the first to occur of sale of the Company, or, sale or transfer to any third party of shares, as a result of which, any person or group other than Vista, obtains possession of voting power to elect a majority of the Company’s board of directors or any other governing body and the achievement of a total equity return multiple of 3.0 or greater.

The 2018 Plan contained a provision wherein, the Time-Based Options can be repurchased by the Company at cost upon resignation of the employee. Due to this repurchase feature, the Time-Based Options did not provide the employee with the potential benefits associated with a stock award holder, and therefore, these awards were not accounted for as a stock-based award under ASC 718,

Compensation -

Stock Compensation

but instead, compensation cost was recognized when the benefit to the employee was determined to be probable. During the three and six months ended June 30, 2021, the Company recognized stock compensation expense of $3,360 related to the stock option exercises. The Return-Target Options were considered to contain both market (total stockholder return threshold) and performance (exit event) conditions. As such, the award was measured on the date of grant. Since the conditions for vesting related to the Return-Target Options were not met prior to the IPO

, no stock-based compensation was recognized in the

pre-IPO

financial statements of the Company.

In connection with the Company’s IPO, the 2018 Plan was amended and restated (“Amended and Restated 2018 Plan”) with the following modifications: (i) the provision to repurchase the Time-Based Options at cost upon resignation of the employee was removed and (ii) the Return-Target Options were modified to include vesting upon a sale of shares by Vista following the IPO resulting in a cumulative total of cash distributions of

$1.17 billion or greater.

As a result of the modification to the Time-Based Options, the awards became subject to the guidance in ASC 718,

Compensation - Stock Compensation

and the fair value of the awards were determined to be

$74,566.

The Company recognized a stock-based compensation expense of

$38,148

in connection with the IPO for the three and six months ended June 30, 2021, based on the options that were vested at the IPO. As the return multiple associated with the Return-Target Options was also modified, the Company fair valued the Return-Target Options using a Monte Carlo simulation model which resulted in a fair value of

$36,156.

As the Return-Target Options only vest upon a change of control, stock-based compensation expense associated with the Return-Target Options will be recognized when such event is deemed probable. As of June 30, 2021, such event was not deemed probable and therefore,

stock-based compensation expense was recognized relating to the Return-Target Options.

The total number of Time-Based Options and Return Target Options issued under the Amended and Restated 2018 Plan as of June 30, 2021 were 5,469,534 and 2,734,766 respectively. The Company does not expect to issue any additional awards under the Amended and Restated 2018 Plan.

2021 Omnibus Incentive Plan (“2021 Plan”)

On July 1, 2021, the Company filed a registration statement on Form S-8 and adopted the 2021 Plan to incentivize executive officers

, management, employees, consultants and directors of the Company and to align the interests of the participants with those of the Company’s shareholders. The Company reserved 19,701,877 shares for issuance under the 2021 Plan and the total number of shares reserved for issuance under the 2021 Plan will be increased on January 1 of each of the first 10 calendar years during the term of the 2021 Plan, by the lesser of (i) 5% of the total number of shares of common stock outstanding on each December 31 immediately prior to the date of increase or (ii) such number of shares of common stock determined by our Board or compensation committee.

The

Company granted an aggregate of 1,883,486 options to purchase shares of common stock consisting of 2/3

or 1,255,496 Time-Based Options fair valued at $14,080 and 1/3

or 627,990 Return-Target Options fair valued at $4,878

under the 2021 Plan. The vesting conditions for the options issued under the 2021 Plan were identical to the those described under the Amended and Restated 2018 Plan. Additionally, the Company granted an aggregate of

969,742

estricted

tock

nits (“RSUs”) to its employees valued at $17,455 that vest 25% each year and become fully vested after four years of service.

2021 Employee Stock Purchase Plan (“ESPP”)

The Company adopted the ESPP for the primary purpose of incentivi

ing employees in future periods. Under the ESPP, 1,489,571 shares of the common stock are reserved for issuance, and the number of shares available for issuance will be increased on January 1 of each calendar year beginning in 2022 and ending in and including 2031, by an amount equal to the lesser of (i) 1% of the shares outstanding on the final day of the immediately preceding calendar year and (ii) such smaller number of shares as is determined by our Board, subject to a maximum of 16,000,000

shares of our common stock for the portion of the ESPP intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code. All Company employees and employees of designated subsidiaries are eligible to participate in the ESPP and can purchase shares through payroll deductions of up to

15%

of their eligible compensation, subject to a maximum of

$25,000

in any annual period for the portion of the ESPP intended to qualify as an employee purchase plan under Section 423 of the Internal Revenue Code. There are

shares issued under the ESPP plan as of June 30, 2021.

Integral Ad Science Holding Corp. Long-Term Incentive Plan

In 2018

, the Company adopted the Long-Term Incentive Plan (“LTIP”). Under the LTIP, certain

employees of the Company and its subsidiaries were granted long-term target incentive cash awards which will be payable subject to continued employment, upon the sale of the Company, or, sale to a third party of at least 50% of the Vista’s equity interest, provided if such sale of equity interests is through a public offering (whether initial or secondary), it would require the transfer of an aggregate of at least 75% of Vista’s equity interest and the achievement of a total equity return multiple of 3.0 or greater.

The total amount of long-term incentive cash awards as of June 30, 2021 and December 31, 2020 was $12,235 and $10,560, respectively. As the multiple is tied to an equity return multiple, any compensation charge associated with these awards is considered equity-based compensation in accordance with U.S. GAAP. Since the liquidity events described above are contingent and generally not considered probable until the event occurs, no stock-based compensation expense has been recognized in the three and six months ended June 30, 2021 and 2020. In July 2021, the Company offered employees with LTIP grants the opportunity to convert the cash award into RSUs. The conversion

was

at a 10% premium to the current value of the award and will vest 50% each year and become fully vested after two years of service.

LTIP grants aggregating $12,661 were converted into 706,526 RSUs and $475 in long-term incentive cash awards remains outstanding under the Amended and Restated LTIP.

Stockholders' Equity Note [Abstract]
Members' / Stockholders' Equity	12. Members’/ Stockholders’ equity As discussed in Note 1, the Company converted to a Delaware corporation, which created new elements of the capital structure at June 30, 2021, and modified existing elements of the capital structure in place at December 31, 2020. Common stock As of June 30, 2021 our authorized common stock consists of 500,000,000 shares of common stock, par value $0.001 per share and 50,000,000 preferred stock, par value $0.001 per share. Members’ equity Prior to the IPO, the Company was an affiliate of Vista, was a single member LLC, and the Company’s Board of Directors, through the Kavacha Topco, LLC Amended and Restated Limited Liability Company Agreement (the “Operating Agreement”), had the authority to admit additional members. Under the terms of the Operating Agreement, the members of the Company were not obligated for debt, liabilities, contracts or other obligations of the Company. Profits and losses are allocated to members as defined in the Operating Agreement. In conjunction with the pricing of the IPO, the Operating Agreement was terminated, and the Company converted from a Del a ware domestic limited liability company to a Del a ware domestic corporation. All outstanding member units were converted into 134,203,403 shares of common stock of the Company on a proportion of 1 member unit for 242 shares of common stock. For the three months ended June 30, 2021 and 2020, certain employees exercised their stock options and the Company issued 246,369 and 0 shares of common stock, respectively. Proceeds received from the exercise of stock options aggregated $1,075 and $0, for the three months ended June 30, 2021 and 2020, respectively.

The repurchases in excess of par value for the six months ended June 30, 2021 and 2020 were $791 and $12, respectively. The repurchase of shares ha s been accounted for as a reduction in members’/shareholders’ equity in these condensed consolidated financial statements.

Commitments and Contingencies

13. Commitments and contingencies

Indemnifications

In its normal course of business, the Company has made certain indemnities, commitments, and guarantees under which it may be required to make payments in relation to certain transactions. Those indemnities include intellectual property indemnities to the Company’s customers, indemnities to directors and officers of the Company to the maximum extent permitted under the laws of the State of Delaware, and indemnifications related to the Company’s lease agreements. In addition, the Company’s advertiser and distribution partner agreements contain certain indemnification provisions which are generally consistent with those prevalent in the Company’s industry. The Company has not incurred any obligations under indemnification provisions historically and does not expect to incur significant obligations in the future. Accordingly, the Company has not recorded any liability for these indemnities, commitments, and guarantees in the accompanying balance sheets.

Operating leases

The Company leases office space under operating leases, which expire on various dates through May 2026. Certain leases relating to office space include scheduled annual rent increases. Rent expense under operating leases is recognized on a straight-line basis over the lease terms. The excess of expense over payments is recorded as accrued rent on the condensed consolidated balance sheets.

Operating lease expense for office space for the three months ending June 30, 2021 and 2020 was $1,862 and $2,044, respectively. Operating lease expense for office space for the six months ending June 30, 2021 and 2020 was $3,711 and $4,174 respectively.

Earnings Per Share [Abstract]

Net loss per share

14. Net loss per share

For periods prior to the Company’s conversation to a Delaware corporation, including fiscal 2020 and 2021 for which a portion of the period preceded the conversion, the Company has retrospectively presented net loss per share as if the conversion had occurred at the beginning of the earliest period presented. The weighted average shares used in computing net loss per share in these periods are based on the number of units held by members after giving effect to the conversion ratio.

Basic and diluted loss per unit is computed by dividing net loss by the weighted-average shares outstanding:


	Three Months Ended June 30,						Six Months Ended June 30,
	2021			2020			2021			2020
Numerator:
Net loss	$	(35,063	)	$	(16,451	)	$	(37,832	)	$	(30,895	)
Denominator:
Weighted averages shares outstanding, basic and diluted		133,981,985			134,050,576			133,996,147			134,051,786

Net loss per share, basic and diluted	$	(0.26	)	$	(0.12	)	$	(0.28	)	$	(0.23	)

As the Company has reported net losses for the periods presented, all potentially dilutive securities are antidilutive. The following potential outstanding Time-Based Service Options were excluded from the computation of diluted net loss per share attributable to common stock/unitholders for the periods presented because including them would have been antidilutive. Since the conditions associated with the vesting of the Return Target Options have not occurred as of the reporting date, such options are excluded from potentially dilutive securities.
