Organization and Operations

1. Organization and Operations

HubSpot, Inc. (the “Company”) provides a cloud-based customer relationship management (“CRM”) Platform, that enables companies to attract, engage, and delight customers throughout the customer experience. The Company’s CRM Platform, comprised of Marketing Hub, Sales Hub, Service Hub, content management system ("CMS") Hub and Operations Hub, features integrated applications, tools, and a native payment solution, that enable businesses to create a cohesive and adaptable customer experience.

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) applicable to interim periods, under the rules and regulations of the United States Securities and Exchange Commission (“SEC”). In the opinion of management, the Company has prepared the accompanying unaudited consolidated financial statements on a basis substantially consistent with the audited consolidated financial statements of the Company as of and for the year ended December 31, 2021, and these consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results of the interim periods presented. All intercompany balances and transactions have been eliminated in consolidation.

The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for any subsequent quarter or for the entire year ending December 31, 2022. The year-end balance sheet data was derived from audited financial statements, but this Form 10-Q does not include all disclosures required under GAAP. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted under the rules and regulations of the SEC.

These interim financial statements should be read in conjunction with the audited consolidated financial statements and related notes contained in the Company’s Annual Report on Form 10-K filed with the SEC on February 14, 2022. There have been no changes in the Company’s significant accounting policies from those that were disclosed in the Company’s Annual Report on Form 10-K that have had a material impact on our consolidated financial statements and related notes, except the adoption of updated guidance related to accounting for convertible debt as described within Note 2 of these consolidated financial statements.

In February 2022, Russian forces launched a military invasion of Ukraine. While the broader implications of the conflict on the Company's results of operations and overall financial performance remain uncertain, the Company assessed the potential impact on the March 31, 2022 financial statements and determined there were no material adjustments necessary with respect to these consolidated financial statements.

Recent Accounting Pronouncements

Recent accounting standards not included below are not expected to have a material impact on our consolidated financial position and results of operations.

In August 2020, the FASB issued guidance simplifying the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being bifurcated from the host contract and separately recognized as compared with current GAAP. In addition, it eliminates the treasury stock method for calculating diluted earnings per share for convertible instruments and requires the use of the if-converted method. The Company adopted the updated guidance as of January 1, 2022 using a modified retrospective method with a cumulative-effect adjustment as of the adoption date. Comparative periods are not adjusted. See Note 8 of these consolidated financial statements for further details.

In October 2021, the FASB issued guidance that requires companies to recognize and measure contract assets and contract liabilities acquired in a business combination, in accordance with the revenue recognition guidance, as if the acquirer had entered into the original contract at the same time and on the same terms as the acquiree. Generally, this will result in the acquirer recognizing contract assets and liabilities at the same amounts recorded by the acquiree as of the acquisition date. Under the previous standard, an acquirer generally recognizes such items at fair value on the acquisition date. The Company adopted the updated guidance as of January 1, 2022 and the ongoing impact of this guidance will depend on the contract assets and liabilities acquired in future business combinations.

2. Revenues

Disaggregation of Revenue

The Company provides disaggregation of revenue based on geographic region (Note 13) and based on the subscription versus professional services and other classification on the consolidated statements of operations as it believes these best depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.

Deferred Revenue and Deferred Commission Expense

Amounts that have been invoiced are recorded in accounts receivable and deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. Deferred revenue represents amounts billed for which revenue has not yet been recognized. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue, and the remaining portion is recorded as long-term deferred revenue. Deferred revenue during the three months ended March 31, 2022 increased by $27.7 million resulting from $423.3 million of additional invoicing and was offset by revenue recognized of $395.6 million during the same period. $227.1 million of revenue was recognized during the three months ended March 31, 2022 that was included in deferred revenue at the beginning of the period. As of March 31, 2022, approximately $406.9 million of revenue is expected to be recognized from remaining performance obligations for contracts with original performance obligations that exceed one year. The Company expects to recognize revenue on approximately 93% of these remaining performance obligations over the next 24 months, with the balance recognized thereafter.

Additional contract liabilities of $2.9 million and $2.5 were included in accrued expenses and other current liabilities on the consolidated balance sheet as of March 31, 2022 and December 31, 2021.

The incremental direct costs of obtaining a contract, which primarily consist of sales commissions paid for new subscription contracts, are deferred and amortized on a straight-line basis over a period of approximately one to three years. The one to three-year period has been determined by taking into consideration the type of product sold, the commitment term of the customer contract, the nature of the Company’s technology development life-cycle, and an estimated customer relationship period. Sales commissions for upgrade contracts are deferred and amortized on a straight-line basis over the remaining estimated customer relationship period of the related customer. Deferred commission expense that will be recorded as expense during the succeeding 12-month period is recorded as current deferred commission expense, and the remaining portion is recorded as long-term deferred commission expense.

Deferred commission expense during the three months ended March 31, 2022 increased by $7.9 million as a result of deferring incremental costs of obtaining a contract of $26.7 million and was offset by amortization of $18.8 million during the same period.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer.

Net Loss per Share

Earnings Per Share [Abstract]

Net Loss per Share

3. Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding for the period. Diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock, restricted stock units (“RSUs”), shares issued pursuant to the Employee Stock Purchase Plan (“ESPP”), the Warrants (defined in Note 8), the Conversion Option of the 2022 Notes, and the Conversion Option of the 2025 Notes (the “Conversion Options”) (Note 8) are considered to be potential common stock equivalents.

A reconciliation of the denominator used in the calculation of basic and diluted net loss per share is as follows:


	Three Months Ended March 31,
	2022			2021
Net loss	$	(9,341	)	$	(23,159	)
Weighted-average common shares outstanding — basic		47,577			46,428
Dilutive effect of share equivalents resulting from stock options, RSUs, ESPP, Warrants and the Conversion Options		—			—
Weighted-average common shares, outstanding — diluted		47,577			46,428
Net loss per share, basic and diluted	$	(0.20	)	$	(0.50	)

Since the Company incurred net losses for each of the periods presented, diluted net loss per share is the same as basic net loss per share. All of the Company’s outstanding stock options, RSUs, and shares issuable under the ESPP, as well as the Warrants and Conversion Options were excluded in the calculation of diluted net loss per share as the effect would be anti-dilutive.

The Company uses the treasury stock method and the average market price per share during the period for calculating any potential dilutive effect of the Warrants. The average stock price for the three months ended March 31, 2022 was $484.47. The Company uses the if-converted method when calculating any potential dilutive effect of the Conversion Options, which assumes conversion of outstanding convertible securities at the beginning of the reporting period or date of issuance, if the convertible security was issued during the period.

Because the last reported sale price of the Company’s common stock for at least 20 trading days during the period of 30 consecutive trading days ending on the last trading day of the calendar quarter ended March 31, 2022 was equal to or greater than 130% of the applicable conversion price of $282.52 on each applicable trading day, the 2025 Notes are convertible at the option of the holders thereof during the calendar quarter ending June 30, 2022. During the quarter ended March 31, 2022, upon the election of the holders to convert, the Company settled $0.9 million of principal balance of the 2025 Notes in cash. Between the end of the most recently completed fiscal quarter and April 29, 2022, the Company has not received additional conversion notices.

On or after February 1, 2022, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert the 2022 Notes at any time. In the quarter ended March 31, 2022 and through April 29, 2022, the Company did not receive any conversion notices. As of March 31, 2022, $19.4 million of principal remains outstanding on the 2022 Notes. For disclosure purposes, the potentially dilutive effect of the conversion spread is calculated and included in the table below.

The following table contains all potentially dilutive common stock equivalents.

	2022		2021

Options to purchase common shares		527		769

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

4. Fair Value of Financial Instruments

The Company measures certain financial assets at fair value. Fair value is determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy, as follows:

•

Level 1 — Quoted prices in active markets for identical assets or liabilities.

•

Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.

•

Level 3 — Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.

The following table details the fair value measurements within the fair value hierarchy of the Company’s financial assets and liabilities at March 31, 2022 and December 31, 2021:

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. The fair value of the Company’s investments in certain money market funds is their face value and such instruments are classified as Level 1 and are included in cash and cash equivalents on the consolidated balance sheets. At March 31, 2022 and December 31, 2021, Level 2 securities were priced by pricing vendors. These pricing vendors utilize the most recent observable market information in pricing these securities or, if specific prices are not available for these securities, use other observable inputs like market transactions involving identical or comparable securities.

As of March 31, 2022, the fair value of the 2022 Notes was $96.9 million and the fair value of the 2025 Notes was $821.4 million. The fair value was determined based on the quoted price of the 2022 and 2025 Notes in an inactive market on the last trading day of the reporting period and has been classified as Level 2 within the fair value hierarchy.

For certain other financial instruments, including accounts receivable, accounts payable, and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these balances.

Restricted cash is comprised of money market funds related to landlord guarantees for leased facilities. These restricted cash balances have been excluded from our cash and cash equivalents balance on our consolidated balance sheets.

Strategic investments consist of non-controlling equity investments in privately held companies. The Company elected the measurement alternative for these investments without readily determinable fair values and for which the Company does not have the ability to exercise significant influence. These investments are accounted for under the cost method of accounting. Under the cost method of accounting, the non-marketable equity securities are carried at cost less any impairment, plus or minus adjustments resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer, which is recorded within the statement of operations. The Company holds $28.1 million of strategic investments without readily determinable fair values at March 31, 2022 and $17.8 million of strategic investments without readily determinable fair values at December 31, 2021. These investments are included in prepaid and other current assets and other assets on the consolidated balance sheets. During the three months ended March 31, 2022, an acquisition of an entity in which the Company held a strategic investment was completed, which resulted in an observable price change. The Company adjusted the fair value of its investment and recognized a gain of $4.2 million reported in the consolidated statements of operations as other income. There were no other adjustments to the carrying value of the strategic investments resulting from impairments or observable price changes in the three months ended March 31, 2022.

The following tables summarize the composition of our short- and long-term investments at March 31, 2022 and December 31, 2021.

Total	$	996,638	$	11	$	(792	)	$	995,857

For all of our securities for which the amortized cost basis was greater than the fair value at March 31, 2022, the Company has concluded that there is no plan to sell the security nor is it more likely than not that the Company would be required to sell the security before its anticipated recovery. In making the determination as to whether the unrealized loss is other-than-temporary, the Company considered the length of time and extent the investment has been in an unrealized loss position, the financial condition and near-term prospects of the issuers, the issuers’ credit rating and the time to maturity.

Contractual Maturities

Adoption of Updated Debt Guidance

On January 1, 2022, the Company adopted the new guidance for convertible instruments using a modified retrospective method. Results for reporting periods beginning after December 31, 2021 are presented under the new guidance, while prior period comparative amounts are not adjusted and continue to be reported in accordance with historical guidance.

The new guidance eliminates the bifurcation and separate recognition of the embedded cash conversion feature from the host contract and allows for the entire amount attributable to the debt to be presented as a liability. The carrying amount of the debt liability will be reduced by the issuance costs associated with the debt issuance as a contra-liability. As there is no longer an equity component of the convertible debt, the discount created by accretion of a component of the convertible debt in equity is eliminated and interest expense is reduced. The deferred tax liability recognized as a result of a difference between the carrying amount and tax basis of the 2022 Notes that was recorded to additional paid-in capital as a component of equity was also reversed. There is no change in the accounting for the Capped Call Options, Warrants, or Convertible Note Hedges as they are classified as equity under both the historical and new guidance.

As a result of the impact of applying the new guidance, the Company recorded an increase to opening retained earnings of $31.4 million as of January 1, 2022, related to the difference in interest expense due to the amortization of the convertible debt discount and reversal of the deferred tax liability under the historical guidance. The resulting impact on the consolidated balance sheet to derecognize the debt issuance cost and conversion option that was allocated to the equity component and to derecognize the remaining convertible debt discount was an increase to debt liability of $69.8 million, of which $0.5 million was recorded to short term debt and $69.3 million was recorded to long-term debt, and a decrease in additional paid-in capital of $101.2 million.

2025 Convertible Senior Notes and Capped Call Options

In June 2020, the Company issued $400 million aggregate principal amount of 0.375% convertible senior notes due June 1, 2025 (the “2025 Notes”) in a private offering and an additional $60 million aggregate principal amount of the 2025 Notes pursuant to the exercise in full of the over-allotment options of the initial purchasers. The interest rate is fixed at 0.375% per annum and is payable semi-annually in arrears on June 1 and December 1 of each year. The total net proceeds from the debt offering, after deducting initial purchase discounts and debt issuance costs, were approximately $450.1 million.

Each $1,000 of principal amount of the 2025 Notes will initially be convertible into 3.5396 shares of the Company’s common stock (the “Conversion Option of the 2025 Notes”), which is equivalent to an initial conversion price of approximately $282.52 per share, subject to adjustment upon the occurrence of certain specified events. On or after March 1, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their 2025 Notes at any time. The 2025 Notes will be convertible at the option of the holders prior to the close of business on the business day immediately preceding March 1, 2025 under certain circumstances as described in the indenture governing the 2025 Notes (the “Indenture”). Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election. The Company expects to settle the principal amount of the 2025 Notes in cash. Because the last reported sale price of the Company’s common stock for at least 20 trading days during the period of 30 consecutive trading days ending on the last trading day of the calendar quarter ended March 31, 2022 was equal to or greater than 130% of the applicable conversion price on each applicable trading day, the 2025 Notes are convertible at the option of the holders thereof during the calendar quarter ending June 30, 2022. During the three months ended March 31, 2022, upon the election of the holders to convert, the Company settled $0.9 million of principal balance of the 2025 Notes in cash. Between the end of the most recently completed fiscal quarter and April 29, 2022, the Company has not received additional conversion notices.

In accordance with GAAP relating to the embedded conversion feature, the Company bifurcated the conversion feature associated with the 2025 Notes and recorded $96.6 million to additional paid-in capital for the conversion feature and the resulting debt discount was being amortized to interest expense. As there is no longer an equity component of the convertible debt under the new standard, the debt issuance cost and conversion option that was allocated to the equity component was derecognized through an adjustment to opening retained earnings.

The net carrying amount of the liability component of the 2025 Notes is as follows:


	As of March 31, 2022			As of December 31, 2021
	(in thousands)
Principal	$	459,083		$	459,999

In connection with the offering of the 2025 Notes, the Company purchased capped call options (“Capped Call Options”) with respect to its common stock for $50.6 million. The Capped Call Options are purchased call options that give the Company the option to purchase up to approximately 1.6 million shares of its common stock for $282.52 per share, which corresponds to the approximate initial conversion price of the 2025 Notes. The Capped Call Options were purchased in order to offset potential dilution to the Company’s common stock upon any conversion of the 2025 Notes, subject to a cap of $426.44 per share, and expire concurrently with the 2025 Notes. The $50.6 million paid for the Capped Call Options is recorded in stockholders’ equity as a reduction in additional paid-in capital and are not accounted for as separate derivative financial instruments.

2022 Convertible Senior Notes, Convertible Note Hedge and Warrant

In May 2017, the Company issued $350.0 million aggregate principal amount of 0.25% convertible senior notes due June 1, 2022 (the “2022 Notes”) in a private offering and an additional $50 million aggregate principal amount of the 2022 Notes pursuant to the exercise in full of the over-allotment options of the initial purchasers. of the 2022 Notes. The interest rate is fixed at 0.25% per

annum and is payable semi-annually in arrears on June 1 and December 1 of each year. The total net proceeds from the debt offering, after deducting initial purchase discounts and debt issuance costs, were approximately $389.2 million.

Each $1,000 principal amount of the 2022 Notes are currently convertible into 10.5519 shares of the Company’s common stock (the “Conversion Option of the 2022 Notes”), which is equivalent to an initial conversion price of approximately $94.77 per share, subject to adjustment upon the occurrence of specified events. On or after February 1, 2022 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election. The Company expects to settle the principal amount of the 2022 Notes in cash. In the quarter ended March 31, 2022 and through April 29, 2022, the Company did not receive any conversion notices. The 2022 Notes are classified as short-term debt. As of March 31, 2022, $19.4 million of principal remains outstanding on the 2022 Notes.

In connection with the offering of the 2022 Notes, the Company entered into convertible note hedge transactions (the “Convertible Note Hedges”) with certain counterparties in which the Company has the option to purchase (subject to adjustment for certain specified events) up to approximately 4.2 million shares of the Company’s common stock at a price of approximately $94.77 per share. The Convertible Note Hedges will be settled in cash or shares, or any combination thereof, in accordance with the settlement method of the 2022 Notes in excess of the par amount, and are expected to settle concurrently with the conversion of the 2022 Notes. In addition, the Company sold warrants (the “Warrants”) to certain bank counterparties whereby the holders of the Warrants have the option to initially purchase (subject to adjustment for certain specified events) a total of approximately 4.2 million shares of the Company’s common stock at a price of $115.8 per share. The amount by which the settlement price exceeds the strike price may be settled in shares or cash at the Company’s election. The Warrants are expected to settle three business days from each trading day commencing on September 1, 2022 and ending on the 79th trading day thereafter. As of March 31, 2022, Convertible Note Hedges giving the Company the option to purchase approximately 0.2 million shares of the Company’s common stock and Warrants giving certain counterparties the option to acquire up to 1.3 million shares of the Company’s common stock remain outstanding.

In accordance with GAAP relating to the embedded conversion feature, the Company bifurcated the conversion feature associated with the 2022 Notes and recorded $18.9 million to additional paid-in capital for the conversion feature and the resulting debt discount was being amortized to interest expense. As there is no longer an equity component of the convertible debt under the new standard, the debt issuance cost and conversion option that was allocated to the equity component was derecognized through an adjustment to opening retained earnings.

The net carrying amount of the liability component of the 2022 Notes is as follows:

The Company leases office facilities under non-cancelable operating leases that expire at various dates through February 2035.

During the three months ended March 31, 2022, the lease term began, was amended, or extended for various leases of office spaces globally. The Company recorded a net $4.8 million of right-of-use assets and $4.8 million of lease liabilities for these leases during the period upon the lease commencement, amendment, or extension.

The Company uses its estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of operating lease payments. To determine the estimated incremental borrowing rate, the Company uses publicly available credit ratings for peer companies. The Company estimates the incremental borrowing rate using yields for maturities that are in line with the duration of the lease payments. The weighted average discount rate for operating leases as of March 31, 2022 was 4.5%.

Operating lease expense costs were $10.9 million for the three months ended March 31, 2022 and $12.0 million for the three months ended March 31, 2021.

13. Segment Information and Geographic Data

The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief operating decision maker (“CODM”), which is the Company’s chief executive officer, in deciding how to allocate resources and assess performance. The Company’s CODM evaluates the Company’s financial information and resources and assesses the performance of these resources on a consolidated basis. Since the Company operates in one operating segment, all required financial segment information can be found in the consolidated financial

statements. Revenue and long-lived assets by geographic region, based on the physical location of the operations recording the sale or the asset, are as follows:

Organization and Operations (Policies)	Mar. 31, 2022
Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recent accounting standards not included below are not expected to have a material impact on our consolidated financial position and results of operations. In August 2020, the FASB issued guidance simplifying the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being bifurcated from the host contract and separately recognized as compared with current GAAP. In addition, it eliminates the treasury stock method for calculating diluted earnings per share for convertible instruments and requires the use of the if-converted method. The Company adopted the updated guidance as of January 1, 2022 using a modified retrospective method with a cumulative-effect adjustment as of the adoption date. Comparative periods are not adjusted. See Note 8 of these consolidated financial statements for further details. In October 2021, the FASB issued guidance that requires companies to recognize and measure contract assets and contract liabilities acquired in a business combination, in accordance with the revenue recognition guidance, as if the acquirer had entered into the original contract at the same time and on the same terms as the acquiree. Generally, this will result in the acquirer recognizing contract assets and liabilities at the same amounts recorded by the acquiree as of the acquisition date. Under the previous standard, an acquirer generally recognizes such items at fair value on the acquisition date. The Company adopted the updated guidance as of January 1, 2022 and the ongoing impact of this guidance will depend on the contract assets and liabilities acquired in future business combinations.
Revenues	isaggregation of Revenue The Company provides disaggregation of revenue based on geographic region (Note 13) and based on the subscription versus professional services and other classification on the consolidated statements of operations as it believes these best depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Deferred Revenue and Deferred Commission Expense Amounts that have been invoiced are recorded in accounts receivable and deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. Deferred revenue represents amounts billed for which revenue has not yet been recognized. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue, and the remaining portion is recorded as long-term deferred revenue. Deferred revenue during the three months ended March 31, 2022 increased by $27.7 million resulting from $423.3 million of additional invoicing and was offset by revenue recognized of $395.6 million during the same period. $227.1 million of revenue was recognized during the three months ended March 31, 2022 that was included in deferred revenue at the beginning of the period. As of March 31, 2022, approximately $406.9 million of revenue is expected to be recognized from remaining performance obligations for contracts with original performance obligations that exceed one year. The Company expects to recognize revenue on approximately 93% of these remaining performance obligations over the next 24 months, with the balance recognized thereafter. Additional contract liabilities of $2.9 million and $2.5 were included in accrued expenses and other current liabilities on the consolidated balance sheet as of March 31, 2022 and December 31, 2021. The incremental direct costs of obtaining a contract, which primarily consist of sales commissions paid for new subscription contracts, are deferred and amortized on a straight-line basis over a period of approximately one to three years. The one to three-year period has been determined by taking into consideration the type of product sold, the commitment term of the customer contract, the nature of the Company’s technology development life-cycle, and an estimated customer relationship period. Sales commissions for upgrade contracts are deferred and amortized on a straight-line basis over the remaining estimated customer relationship period of the related customer. Deferred commission expense that will be recorded as expense during the succeeding 12-month period is recorded as current deferred commission expense, and the remaining portion is recorded as long-term deferred commission expense. Deferred commission expense during the three months ended March 31, 2022 increased by $7.9 million as a result of deferring incremental costs of obtaining a contract of $26.7 million and was offset by amortization of $18.8 million during the same period.
