Accrued expenses and other current liabilities	$	27,166	$	31,247

Indirect tax payables relate to amounts collected from customers on behalf of third-party taxing authorities, primarily on sales in the U.S. and in international jurisdictions. Indirect tax payables also include withholding taxes on payments made to the Company’s instructors before remitting these amounts to the taxing authorities.

As of June 30, 2023, indirect tax reserves consist of the residual interest payable on the Company’s instructor withholding tax reserves and other indirect tax reserves.

Instructor withholding tax reserves—

Prior to March 2020, the Company had not obtained appropriate taxpayer identification forms from instructors, nor remitted applicable tax withholding amounts to the U.S. Internal Revenue Service (“IRS”) where required. In accordance with GAAP, the Company recorded a provision for its tax exposure when it was both probable that a liability had been incurred and the amount of the exposure could be reasonably estimated.

Beginning in March 2020, the Company began collecting appropriate taxpayer identification forms from its instructors, assessing whether the forms justified a reduced rate of withholding or withholding exemption, and remitting withholding tax payments to the IRS where required. The Company also began reporting payments to its non-U.S. instructors and the IRS annually where required to do so.

In 2020, the Company approached the IRS to address the historical tax withholding amounts for instructors and engaged in a voluntary disclosure program. As of June 30, 2023, the Company has filed all outstanding withholding tax returns and has paid the associated tax obligation to the IRS. The estimated interest associated with the reserve is still outstanding.

Changes in the estimated amount the Company has determined it will owe are recorded in general and administrative expenses in the accompanying condensed consolidated statements of operations. Estimated interest is recorded in interest income (expense), net in the accompanying condensed consolidated statement of operations.

Changes to the instructor withholding tax reserve are as follows (in thousands):

Income taxes	6 Months Ended
Income taxes	Jun. 30, 2023
Income Tax Disclosure [Abstract]
Income taxes	9. Income taxes The provision for income taxes for interim periods is determined using an estimate of the Company’s annual effective tax rate, adjusted for discrete items, if any, that are taken into consideration in the relevant period. Each quarter, the Company updates the estimate of the annual effective tax rate, and if the estimated tax rate changes, the Company records a cumulative adjustment to the provision. The Company had an effective tax rate of (4.28)% and (1.10)% for the three months ended June 30, 2023, and 2022 respectively, and (3.10)% and (1.20)% for the six months ended June 30, 2023 and 2022, respectively. The difference between the 21% statutory federal tax rate and the effective tax rate was primarily a result of income earned in jurisdictions with higher statutory tax rates, foreign withholding taxes, and tax credits offset by change in valuation allowance. As of June 30, 2023 and December 31, 2022, the Company has provided a valuation allowance against U.S. federal and state deferred tax assets. Management continues to evaluate the realizability of deferred tax assets and the related valuation allowance. If management's assessment of the deferred tax assets or the corresponding valuation allowance were to change, the Company would record the related adjustment to income during the period in which management makes the determination. The Company recognizes interest and penalties associated with uncertain tax positions as part of the income tax provision. To date, the Company has not recognized any interest and penalties in its condensed consolidated statements of operations, nor has it accrued for or made payments for interest and penalties. The Company is subject to taxation in the U.S. and various foreign jurisdictions. Due to NOL carryforwards and tax credit carryforwards, the statutes of limitations remain open for tax years from inception of the Company through 2022. There are currently no income tax audits underway by U.S. federal or state tax authorities. There is an income audit in India that began in the year ended December 31, 2022, but no notices or assessments have been issued at this time.

- Definition

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.

Fair Value Disclosures [Abstract]

Investments and fair value measurements

4. Investments and fair value measurements

The Company’s assets and liabilities that are measured at fair value on a recurring or nonrecurring basis within the fair value hierarchy are as follows (in thousands):


As of June 30, 2023	Level 1		Level 2		Level 3
Cash equivalents:
Money market funds	$	281,719	$	—	$	—

Marketable securities:
U.S. government securities	$	—	$	142,287	$	—

Non-current assets:
Strategic investments	$	—	$	—	$	10,311

Non-current liabilities:
Cash settled stock appreciation rights	$	—	$	—	$	30


As of December 31, 2022	Level 1		Level 2		Level 3
Cash equivalents:
Money market funds	$	130,377	$	—	$	—
U.S. government securities	—		48,900		—
Total cash equivalents	$	130,377	$	48,900	$	—

Marketable securities:
U.S. government securities	$	—	$	151,687	$	—

Non-current assets:
Strategic investments	$	—	$	—	$	12,104

Non-current liabilities:
Cash settled stock appreciation rights	$	—	$	—	$	462

The Company’s money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted prices in active markets. The Company’s investments in U.S. government securities are classified within Level 2 of the fair value hierarchy because they have been valued using inputs other than quoted prices in active markets that are directly or indirectly observable. The Company’s strategic investment and stock appreciation rights (“SARs”) are classified within Level 3 of the fair value hierarchy because they have been valued using significant unobservable inputs for which the Company has been required to develop its own assumptions.

A summary of the changes in the fair value of Level 3 financial instruments, of which remeasurement of SARs and impairment of strategic investments are recognized in the condensed consolidated statements of operations, is as follows (in thousands):


	Stock Appreciation Rights		Strategic Investments
Balance— March 31, 2023	$	264	$	12,104
Vesting and remeasurement of SARs	19		—
Exercises of SARs	(253)		—
Unrealized loss on strategic investments	—		(1,793)
Balance— June 30, 2023	$	30	$	10,311

Balance— March 31, 2022	$	508	$	15,000

The Company evaluates its strategic investment for impairment at each reporting period. This evaluation consists of several potential qualitative and quantitative impairment indicators including, but not limited to, the investee's financial metrics, whether there were any significant adverse changes in the economic environment or general market conditions of the geographies and industries in which the investee operates, and any other publicly available information that may affect the value of the investment. Based on the assessment performed as of June 30, 2023, the Company recorded an impairment loss of $1.8 million during the three and six months ended June 30, 2023. The difference between the strategic investment’s cost basis of $15.0 million and the carrying value of $10.3 million is due to cumulative impairment charges of $4.7 million recorded through June 30, 2023.

Share-Based Payment Arrangement [Abstract]

Stockholders' equity

11. Stockholders' equity

Preferred stock— In connection with the IPO, the Company’s amended and restated certificate of incorporation became effective, which authorized the issuance of 50,000,000 shares of undesignated preferred stock with a par value of $0.00001 per share with rights and preferences, including voting rights, designated from time to time by the board of directors.

Common stock— Common stockholders are entitled to one vote per share. As of June 30, 2023 and December 31, 2022, the following shares of common stock were available for future issuance:


	June 30,	December 31,
	2023	2022
2010 Equity Incentive Plan:
Stock options outstanding	8,836,101	10,333,771
2021 Equity Incentive Plan:
RSUs outstanding and PSUs(1)	18,667,968	16,178,101
Shares available for future issuance under:
2021 Equity Incentive Plan	4,865,969	2,814,126
2021 Employee Stock Purchase Plan	2,754,604	1,929,578
Total shares of common stock reserved	35,124,642	31,255,576
(1) The number of PSUs reserved for issuance is based on the maximum achievement of the corporate performance metric.

Equity incentive plans— In 2010, the Company adopted the 2010 Equity Incentive Plan (the “2010 Plan”). The 2010 Plan provided for incentive stock options (“ISOs”), non-statutory stock options (“NSOs”, collectively with ISOs, “stock options”), SARs, restricted stock, and restricted stock units (“RSUs”) to be granted to eligible employees, directors, and consultants. The 2010 Plan was terminated in October 2021 in connection with the IPO but continues to govern the terms and conditions of the outstanding awards granted pursuant to the 2010 Plan. No further equity awards will be granted under the 2010 Plan.

The Company adopted the 2021 Equity Incentive Plan (the "2021 Plan") in September 2021, which became effective on October 28, 2021 (collectively with the 2010 Plan, the “Equity Incentive Plans”) and was approved by the Company’s stockholders. The 2021 Plan provides for the granting of ISOs, NSOs, SARs, restricted stock, RSUs, and performance awards to eligible employees, directors, and consultants.

The Company initially reserved 13,800,000 shares for issuance under the 2021 Plan. The amount available for issuance is subject to an annual increase on the first day of each calendar year, beginning on January 1, 2023, in an amount equal to 5% of the outstanding shares of the Company’s common stock on the last day of the immediately preceding calendar year or a lesser amount determined by the Company’s Board of Directors or compensation committee. The amount available for issuance shall also include Returning Shares, which are any shares subject to awards granted under the 2010 Plan that, on or after October 29, 2021, expire or otherwise terminate without having been exercised in full, are tendered to or withheld by the Company for payment of an exercise price or for tax withholding obligations, or are forfeited to or repurchased by the Company due to failure to vest. On January 1, 2023, the shares available for future grants under the 2021 Plan automatically increased by 7,250,689 pursuant to the above evergreen provision of the 2021 Plan.

Stock options— The Company may grant stock options at exercise prices not less than the fair market value at the date of grant. These options generally expire 10 years from the date of grant. The Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period for each award, which is generally even over four years.

The following is a summary of activity for stock options having only service-based vesting conditions under the Equity Incentive Plans:


	Options Outstanding	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value (In Thousands)
Balance - December 31, 2022	10,283,771	$	4.18	6.38	$	66,234
Granted	—	—
Exercised	(1,362,403)	3.51
Canceled	(135,267)	9.32
Balance - June 30, 2023	8,786,101	$	4.21	2.82	$	57,714
Vested & expected to vest as of June 30, 2023	8,786,101	$	4.21	2.82	$	57,714
Exercisable as of June 30, 2023	8,202,806	$	4.03	2.73	$	55,236

There were no stock options granted during the six months ended June 30, 2023 or 2022. The decrease in weighted average remaining contractual term during the period is due to stock options held by the Company’s former CEO, Mr. Coccari, which will expire if not exercised by the end of the 90-day post-termination exercise window that begins upon completion of his transition agreement in February 2024. Refer to further discussion below under other equity transactions.

As of June 30, 2023, total unrecognized stock-based compensation expense related to unvested stock options was $1.5 million, which will be recognized over a weighted average period of 0.7 years.

Stock appreciation rights— The Company may grant SARs at exercise prices not less than the fair market value at the date of grant. The SARs are liability-classified awards that generally expire 10 years from the date of grant. The Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period for each award, which is generally even over four years.

The following is a summary of activity for SARs under the Equity Incentive Plans:


	SARs Outstanding	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value (In Thousands)
Balance - December 31, 2022	81,770	$	5.44	6.90	$	418
Granted	—	—
Exercised	(67,781)	5.30
Canceled	(9,289)	6.58
Balance - June 30, 2023	4,700	$	5.11	6.48	$	26
Vested & expected to vest as of June 30, 2023	4,700	$	5.11	6.48	$	26
Exercisable as of June 30, 2023	4,199	$	4.95	6.45	$	24

There were no SARs granted during the six months ended June 30, 2023 or 2022.

As of June 30, 2023, total unrecognized stock-based compensation expense related to unvested SARs was immaterial.

Restricted stock units and performance-based restricted stock units— The fair value of RSUs is determined using the fair value of the Company’s common stock on the date of grant. The Company recognizes stock-based compensation expense for RSUs with service-based vesting conditions on a straight-line basis over the requisite service period for each award, which typically vest over a three or four-year period.

During the first quarter of 2023, the Company granted 645,833 PSUs to certain executives at target. Each PSU conveys a right to receive one share of the Company’s common stock on the date it vests, provided that the number of PSUs that will ultimately vest may vary from 0% to 150% of target based upon the achievement of the corporate performance metric at the end of the performance period. One quarter of the eligible PSUs vest upon certification of the corporate performance metric in the first quarter of 2024, and the remaining 75% will vest equally over the following 12 quarters thereafter, subject to continual service by the grantee. Total stock-based compensation expense to be recognized may fluctuate during the performance period due to changes in forecasted achievement. The corporate performance metric associated with these awards has been considered probable of being achieved since the grant date, and as of June 30, 2023, management estimated a payout rate equal to 83% of the number of target shares granted.

A summary of RSU and PSU activity under the 2021 Plan is as follows:


	RSUs Outstanding	Weighted Average Grant Date Fair Value		PSUs Outstanding	Weighted Average Grant Date Fair Value
Unvested - December 31, 2022	16,178,101	$	17.37	—	$	—
Granted	5,908,855	$	9.31	645,833	$	8.89
Released	(2,844,246)	$	16.92	—	$	—
Canceled	(1,543,474)	$	16.31	—	$	—
Unvested - June 30, 2023	17,699,236	$	14.84	645,833	$	8.89

As of June 30, 2023, total unrecognized stock-based compensation expense related to unvested RSUs was $224.1 million, which will be recognized over a weighted average period of 3.0 years.

As of June 30, 2023, total unrecognized stock-based compensation expense related to unvested PSUs was $3.9 million, which will be recognized over a weighted average period of 1.9 years.

Performance-based stock options— There have been no other changes to the Company’s performance-based stock options compared to those described in Note 14— Stockholders’ equity, included in Part II, Item 8 of the Company’s Annual Report.

As of June 30, 2023, there were 50,000 performance-based stock options outstanding, of which 19,791 were exercisable. As of June 30, 2023, total unrecognized stock-based compensation expense related to unvested performance-based stock options was immaterial.

Employee stock purchase plan— The 2021 Employee Stock Purchase Plan (the “ESPP”) became effective on October 29, 2021. The Company initially reserved 2,800,000 shares of the Company's common stock under the ESPP. Shares reserved for issuance shall increase on the first day of the fiscal year, beginning in fiscal 2023, in an amount equal to the least of 1% of the outstanding shares of common stock on the last day of the immediately preceding fiscal year, three times the initial number of shares reserved under the ESPP, or a lesser amount determined by the Company’s Board of Directors or compensation committee. On January 1, 2023, the shares available for future grants under the ESPP automatically increased by 1,450,137 pursuant to the above evergreen provision of the 2021 ESPP.

During the six months ended June 30, 2023, 625,111 shares of common stock were issued under the ESPP.

On May 20, 2023, the Company’s ESPP purchase price was reset for both the May 2022 and November 2022 offering periods. Under the reset provision, if the closing stock price on the purchase date falls below the closing stock price on the offering date of an ongoing offering period, the ongoing offering terminates immediately following the purchase of ESPP shares on the purchase date. Participants in the terminated offering are then automatically enrolled in the new offering period. The ESPP reset resulted in incremental compensation cost of $5.9 million which, along with the unrecognized expense remaining from the original grant date fair value, will be recognized on a straight-line basis over the new offering period ending in May 2025.


			Three and Six Months Ended
			June 30, 2023
Risk-free interest rate			4.5%
Expected volatility			69.7%
Expected life (in years)			1.6
Expected dividend yield			—%

As of June 30, 2023, total unrecognized compensation cost for the ESPP was $11.2 million, which will be recognized on a straight-line basis over the next 1.9 years.

Other equity transactions— On February 28, 2023, the Company entered into a transition agreement with Mr. Coccari under which he will provide transition advice through February 28, 2024. During the transition period, he will continue to meet the definition of a service provider under the 2021 Plan, and his equity incentive awards will continue to vest in accordance with their original vesting schedules. Because the scope of services to be provided under the transition period represent a substantive reduction in services being provided by the former CEO, the Company recognized $3.1 million in stock-based compensation expense during the three months ended March 31, 2023, that would have otherwise been recognized from April 2023 to February 2024.

On August 24, 2021, the Company issued 61,300 shares of Udemy restricted common stock to a former executive of CorpU at a grant date fair value per share of $34.14. The total compensation cost recognized during both the three months ended June 30, 2023 and 2022 was $0.1 million, and $0.3 million for both the six months ended June 30, 2023 and 2022. As of June 30, 2023, total compensation cost related to the restricted stock not yet recognized was $0.8 million, which will be recognized on a straight-line basis over the next 1.2 years.

Total stock-based compensation expense included in the condensed consolidated statements of operations was as follows (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022

Summary of significant accounting policies (Policies)	6 Months Ended
Summary of significant accounting policies (Policies)	Jun. 30, 2023
Accounting Policies [Abstract]
Basis of consolidation and presentation	Basis of consolidation and presentation— The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation, and all other normal and recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results of the periods presented have been made.
Segment information	Segment information— On March 1, 2023, Greg Brown became the Company’s new Chief Executive Officer and chief operating decision maker (“CODM”). The Company defines its segments as those operations the CODM regularly reviews to allocate resources and assess performance. For the three and six months ended June 30, 2023 and 2022, the Company operated under two operating and reportable segments: Enterprise and Consumer. The Company continually monitors and reviews its segment reporting structure in accordance with Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting, to determine whether any changes have occurred that would impact its reportable segments. For further information on the Company’s segment reporting, see Note 13 – Segment and geographic information.
Use of estimates	Use of estimates— The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the condensed consolidated financial statements and the results of operations during the reporting periods. Significant estimates and assumptions reflected in the condensed consolidated financial statements include, but are not limited to, allowance for credit losses, capitalization of internally developed software and associated useful lives, stock-based compensation, determination of the income tax valuation allowance and the potential outcome of uncertain tax positions, estimated instructor withholding tax obligations, estimated service period for consumer single course purchases, the period of benefit for deferred commissions, the fair value and associated useful lives of intangible assets and goodwill acquired via business combinations, and the valuation of privately-held strategic investments, including impairments. Management periodically evaluates such estimates and assumptions for continued reasonableness. Actual results may ultimately differ from management’s estimates and such differences could be material to the Company’s financial position and results of operations.
Concentration of credit risk	Concentration of credit risk— Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, restricted cash, and accounts receivable. For cash and restricted cash, the Company is exposed to credit risk in the event of default by the financial institutions to the extent the amounts recorded on the accompanying condensed consolidated balance sheets are in excess of federal insurance limits. The Company’s investments, classified as cash equivalents and marketable securities, consist of high-credit-quality instruments and fixed-income securities.The Company generally does not require collateral or other security in support of accounts receivable. To reduce credit risk, management performs ongoing evaluations of its customers’ financial condition and maintains an allowance based upon expected credit losses of outstanding receivables.
Stock-based compensation	Stock-based compensation— The Company accounts for its stock-based compensation pursuant to ASC Topic 718, Compensation-Stock Compensation. The Company granted performance-based restricted stock units (“PSUs”) in the first quarter of 2023, which vest based on the achievement of predefined corporate performance metrics and are subject to ongoing service conditions. The Company determines the fair value of PSUs based on the fair value of the Company’s common stock on the date of grant. Because PSUs have both performance and service-based vesting conditions, the Company separately attributes stock-based compensation expense for each vesting tranche of the award over their requisite service periods. Management estimates the number of PSUs that are expected to vest based on the anticipated achievement of the specified performance metrics. If the performance-based vesting condition is considered probable of being achieved, the Company recognizes expense over the requisite service period based on the probable outcome of achievement. If the performance goals are not met, or are considered improbable, no compensation cost is recognized, and any previously recognized compensation cost is reversed.
Accounts receivable, net	Accounts receivable, net— Accounts receivable primarily represent amounts owed to the Company for Enterprise subscriptions. Also included in accounts receivable are amounts due from payment processors or mobile application store partners that settle over a period longer than five business days. Accounts receivable balances are recorded at the invoiced amount and are non-interest-bearing. Accounts receivable is presented net of allowance for credit losses in the accompanying condensed consolidated balance sheets. The Company maintains an allowance based upon expected credit losses of outstanding receivables. Management derives its estimate using a variety of factors, including historical collection and loss patterns; the current aging of receivables; geographic and other customer-specific credit risk factors; and reasonable and supportable forecasts of future economic conditions which inform adjustments to historical loss patterns. The provision for expected credit losses is recorded in general and administrative expenses in the accompanying condensed consolidated statements of operations. Accounts receivable deemed to be uncollectible are written off, net of expected or actual recoveries.
Self-insurance	Self-insurance— Beginning in 2023, the Company became self-insured for medical benefits offered to certain employees, up to certain stop-loss limits. Such costs are accrued based on known claims and estimates of incurred but not reported (“IBNR”) claims. IBNR claims are estimated using historical claim information and actuarial estimates
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Recently Issued Accounting Pronouncements Not Yet Adopted There are no recently issued accounting pronouncements that are expected to have a material impact on the Company’s condensed consolidated financial statements.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	8. Commitments and contingencies Noncancellable purchase commitments— The Company has contractual commitments with its cloud infrastructure provider, network service providers and paid advertising vendors that are noncancellable. As of June 30, 2023, the Company had $56.7 million worth of future minimum payments under the Company’s noncancellable purchase commitments which are expected to be paid through 2026. Indemnification— The Company enters into indemnification provisions under agreements with other parties in the ordinary course of business, including certain business partners, investors, contractors, and the Company’s officers, directors, and certain employees. The Company has agreed to indemnify and defend the indemnified party’s claims and related losses suffered or incurred by the indemnified party resulting from actual or threatened third-party claims because of the Company’s activities or, in some cases, non-compliance with certain representations and warranties made by the Company. In general, the Company does not record any liability for these indemnities in the accompanying condensed consolidated balance sheets as the amounts cannot be reasonably estimated and are not considered probable. The Company does, however, accrue for losses for any known contingent liability, including those that may arise from indemnification provisions, when future payment is probable. To date, losses recorded in the Company’s condensed consolidated statements of operations in connection with the indemnification provisions have not been material. Litigation— From time to time, in the ordinary course of business, the Company is subject to legal proceedings, claims, investigations, and other proceedings, including claims of alleged infringement of third-party patents and other intellectual property rights, and commercial, employment, and other matters. In accordance with generally accepted accounting principles, the Company makes a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least annually and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. The outcome of such litigation is not expected to have a material effect on the financial position, results of operation and cash flows of the Company. The Company has recorded an immaterial amount related to all outstanding litigation matters in the accompanying condensed consolidated balance sheets, within accrued expenses and other current liabilities as of June 30, 2023, and December 31, 2022.

Accounting Policies [Abstract]

Summary of significant accounting policies

2. Summary of significant accounting policies

Basis of consolidation and presentation— The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation, and all other normal and recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results of the periods presented have been made.

Segment information— On March 1, 2023, Greg Brown became the Company’s new Chief Executive Officer and chief operating decision maker (“CODM”). The Company defines its segments as those operations the CODM regularly reviews to allocate resources and assess performance. For the three and six months ended June 30, 2023 and 2022, the Company operated under two operating and reportable segments: Enterprise and Consumer. The Company continually monitors and reviews its segment reporting structure in accordance with Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting, to determine whether any changes have occurred that would impact its reportable segments. For further information on the Company’s segment reporting, see Note 13 – Segment and geographic information.

Use of estimates— The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the condensed consolidated financial statements and the results of operations during the reporting periods.

Significant estimates and assumptions reflected in the condensed consolidated financial statements include, but are not limited to, allowance for credit losses, capitalization of internally developed software and associated useful lives, stock-based compensation, determination of the income tax valuation allowance and the potential outcome of uncertain tax positions, estimated instructor withholding tax obligations, estimated service period for consumer single course purchases, the period of benefit for deferred commissions, the fair value and associated useful lives of intangible assets and goodwill acquired via business combinations, and the valuation of privately-held strategic investments, including impairments. Management periodically evaluates such estimates and assumptions for continued reasonableness.

Actual results may ultimately differ from management’s estimates and such differences could be material to the Company’s financial position and results of operations.

Concentration of credit risk— Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, restricted cash, and accounts receivable. For cash and restricted cash, the Company is exposed to credit risk in the event of default by the financial institutions to the extent the amounts recorded on the accompanying condensed consolidated balance sheets are in excess of federal insurance limits. The Company’s investments, classified as cash equivalents and marketable securities, consist of high-credit-quality instruments and fixed-income securities.

The Company generally does not require collateral or other security in support of accounts receivable. To reduce credit risk, management performs ongoing evaluations of its customers’ financial condition and maintains an allowance based upon expected credit losses of outstanding receivables. The Company had no customers which accounted for more than 10% of accounts receivable as of June 30, 2023 or December 31, 2022. No customer accounted for more than 10% of total revenue during the three and six months ended June 30, 2023 or 2022.

Summary of significant accounting policies— Except as described below, there were no significant changes to the Company’s significant accounting policies disclosed in Note 2 – Summary of significant accounting policies of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was filed with the SEC on February 27, 2023 (the “Annual Report”).

Stock-based compensation— The Company accounts for its stock-based compensation pursuant to ASC Topic 718, Compensation-Stock Compensation.

The Company granted performance-based restricted stock units (“PSUs”) in the first quarter of 2023, which vest based on the achievement of predefined corporate performance metrics and are subject to ongoing service conditions. The Company determines the fair value of PSUs based on the fair value of the Company’s common stock on the date of grant. Because PSUs have both performance and service-based vesting conditions, the Company separately attributes stock-based compensation expense for each vesting tranche of the award over their requisite service periods.

Management estimates the number of PSUs that are expected to vest based on the anticipated achievement of the specified performance metrics. If the performance-based vesting condition is considered probable of being achieved, the Company recognizes expense over the requisite service period based on the probable outcome of achievement. If the performance goals are not met, or are considered improbable, no compensation cost is recognized, and any previously recognized compensation cost is reversed.

Accounts receivable, net— Accounts receivable primarily represent amounts owed to the Company for Enterprise subscriptions. Also included in accounts receivable are amounts due from payment processors or mobile application store partners that settle over a period longer than five business days. Accounts receivable balances are recorded at the invoiced amount and are non-interest-bearing. Accounts receivable is presented net of allowance for credit losses in the accompanying condensed consolidated balance sheets.

The Company maintains an allowance based upon expected credit losses of outstanding receivables. Management derives its estimate using a variety of factors, including historical collection and loss patterns; the current aging of receivables; geographic and other customer-specific credit risk factors; and reasonable and supportable forecasts of future economic conditions which inform adjustments to historical loss patterns. The provision for expected credit losses is recorded in general and administrative expenses in the accompanying condensed consolidated statements of operations. Accounts receivable deemed to be uncollectible are written off, net of expected or actual recoveries.

Self-insurance— Beginning in 2023, the Company became self-insured for medical benefits offered to certain employees, up to certain stop-loss limits. Such costs are accrued based on known claims and estimates of incurred but not reported (“IBNR”) claims. IBNR claims are estimated using historical claim information and actuarial estimates. As of June 30, 2023, the accrued liability for self-insurance totaled $1.1 million and is included in accrued compensation and benefits on the condensed consolidated balance sheets.

Restructuring charges

14. Restructuring charges

On February 13, 2023, the Company communicated to its employees that in response to current macroeconomic conditions and to further streamline its operations and cost structure, it would reduce its global workforce by approximately 10%. As a result, the Company recognized restructuring charges of $10.1 million in the first quarter of 2023, primarily consisting of $8.9 million of personnel expenses such as salaries and wages, one-time severance payments, and other benefits. The Company also recognized $1.2 million of stock-based compensation expense on the communication date, resulting from impacted employees having no future substantive service requirement but continuing to vest into their equity awards during legally required retention periods as well as certain modifications to enable additional vesting after impacted employees’ termination dates. The Company expects the restructuring to be complete by the end of the third quarter of 2023.

Restructuring charges are presented as separate operating expenses within the Company’s condensed consolidated statements of operations. The following table summarizes the activity related to the restructuring liability recorded in accrued compensation and benefits in the accompanying condensed consolidated balance sheets (in thousands):
