Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include accounts of the Company and all wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Revision of Previously Issued Financial Statements In preparing the Company’s consolidated financial statements for the three and six months ended June 30, 2023, the Company identified errors primarily related to the Company’s accounting for income tax expense, of which $3.5 million results in the understatement of its reported loss for the year ended December 31, 2022. The Company assessed the materiality of the errors both quantitatively and qualitatively and determined these errors to be immaterial to the 2022 consolidated financial statements. However, the Company concluded that the effect of correcting the errors in 2023 (in aggregation with other 2023 errors) would materially misstate the Company’s unaudited consolidated financial statements for the three months ended March 31, 2023 and, accordingly, determined that it was necessary to revise the consolidated financial statements it previously issued with respect to the year ended December 31, 2022. The remainder of the notes to the Company's consolidated financial statements have been updated and revised, as applicable, to reflect the impacts of the adjustments described in this Note 2. The following table presents the impact of correcting the errors previously discussed on the affected line items as of and for the year ended December 31, 2022: December 31, 2022 Consolidated Balance Sheet As Previously Reported Adjustments As Revised Prepaid expenses and other current assets $ 28,485 $ (561) $ 27,924 Total current assets $ 946,552 $ (561) $ 945,991 Goodwill $ 313,718 $ 1,450 $ 315,168 Operating lease right-of-use assets, net $ 154,501 $ (800) $ 153,701 Other assets $ 6,353 $ (366) $ 5,987 Total assets $ 1,815,908 $ (277) $ 1,815,631 Operating lease liabilities, current $ 57,682 $ (250) $ 57,432 Other current liabilities $ 45,913 $ 1,496 $ 47,409 Total Current Liabilities $ 164,270 $ 1,246 $ 165,516 Deferred tax liabilities $ 18,209 $ 2,548 $ 20,757 Operating lease liabilities, non-current $ 108,243 $ (550) $ 107,693 Total Liabilities $ 1,764,818 $ 3,244 $ 1,768,062 Accumulated deficit $ (210,821) $ (3,521) $ (214,342) Total Stockholders’ Equity $ 51,090 $ (3,521) $ 47,569 Total liabilities and stockholders’ equity $ 1,815,908 $ (277) $ 1,815,631 December 31, 2022 Consolidated Statements of Operations As Previously Reported Adjustments As Revised Sales and marketing $ 81,544 $ (522) $ 81,022 Total operating expenses $ 390,614 $ (522) $ 390,092 Loss from operations $ (26,219) $ 522 $ (25,697) Loss before income taxes $ (24,407) $ 522 $ (23,885) Income tax (benefit) expense $ (124) $ 4,043 $ 3,919 Net loss attributable to common stockholders $ (24,283) $ (3,521) $ (27,804) Net loss per share attributable to common stockholders, basic and diluted $ (0.24) $ (0.04) $ (0.28) December 31, 2022 Consolidated Statements of Comprehensive Loss As Previously Reported Adjustments As Revised Net loss attributable to common stockholders $ (24,283) $ (3,521) $ (27,804) Comprehensive loss $ (25,957) $ (3,521) $ (29,478) December 31, 2022 Consolidated Statements of Convertible Preferred Stock and Stockholders' Equity (Deficit) As Previously Reported Adjustments As Revised Net loss attributable to common stockholders $ (24,283) $ (3,521) $ (27,804) Accumulated deficit $ (210,821) $ (3,521) $ (214,342) Total stockholders’ equity $ 51,090 $ (3,521) $ 47,569 December 31, 2022 Consolidated Statements of Cash Flows As Previously Reported Adjustments As Revised Net loss attributable to common stockholders $ (24,283) $ (3,521) $ (27,804) Deferred income taxes $ (4,383) $ 2,548 $ (1,835) Prepaid expenses and other current assets $ (535) $ (889) $ (1,424) Other assets and liabilities $ (3,637) $ 1,862 $ (1,775) Reclassifications Certain prior year amounts have been reclassified and revised to conform to the current year presentation. Such reclassifications did not affect total revenues, operating income, or net income. Use of Estimates The preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make, on an ongoing basis, estimates, judgments and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Such estimates include, but are not limited to, those related to revenue recognition, accounts receivable and related reserves, useful lives and realizability of long lived assets, capitalized internal-use software development costs, accounting for stock-based compensation, the incremental borrowing rate we use to determine lease liabilities, valuation allowances against deferred tax assets, and the fair value and useful lives of tangible and intangible assets acquired and liabilities assumed resulting from business combinations. Management bases its estimates on historical experience and on various other assumptions which management believes to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Cash and Cash Equivalents Cash and cash equivalents consist of highly liquid investments in money market funds, commercial paper and certificates of deposit, with original maturities from the date of purchase of three months or less. The carrying amounts of cash and cash equivalents approximate fair value because of the short-term maturity and highly liquid nature of these instruments. Marketable Securities The Company’s marketable securities consist of commercial paper, U.S. treasury securities and commercial debt securities. The Company determines the appropriate classification of its marketable securities at the time of purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for its marketable securities as available-for-sale securities as the Company may sell these securities at any time for use in its current operations or for other purposes, even prior to maturity. As a result, the Company classifies its marketable securities within Current assets on the Consolidated Balance Sheets. Available-for-sale securities are recorded at fair value each reporting period. Premiums and discounts are amortized or accreted over the life of the related available-for-sale security as an adjustment to yield using the effective interest method. Interest income is recognized when earned. Unrealized gains and losses on these marketable securities are presented net of tax and reported as a separate component of Accumulated other comprehensive loss until realized. Realized gains and losses are determined based on the specific identification method and are reported in Other (income) expense, net in the Consolidated Statements of Operations. The Company periodically evaluates its marketable securities to assess whether an investment’s fair value is less than its amortized cost basis and if the decline in the fair value is attributable to a credit loss. Declines in fair value judged to be related to credit loss are reported in Other (income) expense, net in the Consolidated Statements of Operations. Foreign Currency The reporting currency of the Company is the United States dollar (“USD”). The functional currency of the Company is USD, and the functional currency of the Company’s subsidiaries is primarily the local currency of the jurisdiction in which the foreign subsidiary is located. The assets and liabilities of the Company’s subsidiaries are translated to USD at exchange rates in effect at the balance sheet date. All income statement accounts are translated at monthly average exchange rates. Resulting foreign currency translation adjustments are recorded directly in Accumulated other comprehensive (loss) income. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in Other (income) expense, net on the Consolidated Statements of Operations when realized. Restricted Cash The following table reconciles cash, cash equivalents and restricted cash per the Consolidated Statements of Cash Flows: December 31, 2022 2021 Cash and cash equivalents $ 140,772 $ 1,713,387 Restricted cash included in Prepaid expenses and other current assets (1) 9,100 — Restricted cash (2) 1,935 2,038 Total cash, cash equivalents and restricted cash $ 151,807 $ 1,715,425 ___________________ (1) Includes contingent compensation related to the Cloudways acquisition. (2) Includes deposits in financial institutions related to letters of credit used to secure lease agreements. Accounts Receivable Net of Allowance for Expected Credit Losses Accounts receivable primarily represents revenue recognized that was not invoiced at the balance sheet date and is primarily billed and collected in the following month. Trade accounts receivable are carried at the original invoiced amount less an estimated allowance for expected credit losses based on the probability of future collection. Management determines the adequacy of the allowance based on historical loss patterns, the number of days that customer invoices are past due, reasonable and supportable forecasts of future economic conditions to inform adjustments over historical loss data, and an evaluation of the potential risk of loss associated with specific accounts. When management becomes aware of circumstances that may further decrease the likelihood of collection, it records a specific allowance against amounts due, which reduces the receivable to the amount that management reasonably believes will be collected. The Company records changes in the estimate to the allowance for expected credit losses through provision for expected credit losses and reverses the allowance after the potential for recovery is considered remote. The following table presents the changes in our allowance for expected credit losses for the period presented: December 31, 2022 2021 Balance as of December 31, 2021 $ 4,212 $ 3,104 Provision for expected credit losses 16,551 9,207 Write-offs and other (14,664) (8,099) Balance as of December 31, 2022 $ 6,099 $ 4,212 Fair Value of Financial Instruments The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities that are required to be recorded at fair value, the Company considers the principal or most advantageous market in which to transact and the market-based risk. The Company applies fair value accounting for all financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The carrying amounts reported in the consolidated financial statements approximate the fair value for cash and cash equivalents, restricted cash, accounts receivable, accounts payable, and accrued expenses due to their short-term nature. The carrying amount of the Company’s debt is classified as Level 2 due to limited trading activity of the 0% Convertible Senior Notes due December 1, 2026 . Property and Equipment Property and equipment is stated at cost, net of accumulated depreciation. Depreciation on property and equipment is calculated using the straight-line method over the estimated useful lives of the assets and is included in depreciation and amortization expense in the Consolidated Statements of Operations. The estimated useful lives of property and equipment are as follows: Property and Equipment Category Useful Life Computers and equipment 5 years Furniture and fixtures 5 years Leasehold improvements Lesser of lease term or remaining useful life Internal-use software 3 years The Company periodically reviews the estimated useful lives of property and equipment. Leases The Company determines if an arrangement is a lease at contract inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and current and noncurrent operating lease liabilities on the Company’s Consolidated Balance Sheets for the year ended December 31, 2022. ROU assets represent the Company’s right to use an underlying asset for the lease term and the corresponding lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of the unpaid lease payments over the lease term. Lease payments used to measure lease liabilities include fixed lease payments at the lease commencement date. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the lease terms and economic environment at commencement date, in determining the present value of future payments. The ROU asset is measured as the amount of the initial lease liability and adjusted for initial direct costs, lease payments made at or before the commencement date, and reduced by tenant incentives received. The Company does not include options for renewal periods or periods beyond the termination dates in the lease in the measurement of ROU assets and lease liabilities until it is reasonably certain that those options will be exercised based on management's assessment of various relevant factors including economic, entity specific, and market-based factors among others. The Company has lease agreements with lease and non-lease components, which it has elected to combine for all asset classes. The non-lease components primarily consist of power. Fixed payments for non-lease components are considered part of the lease component and included in the measurement of the ROU assets and liabilities, and variable payments are expensed as incurred. Lease expenses for lease payments under operating leases are recognized on a straight-line basis over the lease term. For leases with a term of 12 months or less (short-term leases), the Company elected to not recognize the ROU asset or lease liability and the lease payments are recognized in the Consolidated Statements of Operations on a straight-line basis over the lease term. The Company’s operating lease costs for colocation data center facilities are included in Cost of revenue in the Consolidated Statements of Operations and the operating lease costs for corporate offices are included in General and administrative expenses in the Consolidated Statements of Operations. Capitalization of Internal-Use Software Development Costs Capitalization of costs incurred in connection with software developed for internal-use commences when both the preliminary project stage is completed and management has authorized further funding for the project, based on a determination that it is probable the project will be completed and used to perform the function intended. Capitalized costs include external consulting fees, payroll and payroll-related costs, and stock-based compensation for employees on development teams who are directly associated with, and who devote time to, internal-use software projects during the application development stage. Capitalization of such costs ceases no later than the point at which the project is substantially complete and ready for its intended use. Costs incurred during the planning, training, and post-implementation stages of the software development lifecycle are expensed as incurred and have been included in Research and development expense on the Consolidated Statements of Operations. Impairment of Long-Lived Assets Long-lived assets, including property and equipment, intangible assets with definite lives and ROU assets, are reviewed for impairment when circumstances indicate the carrying value of an asset may not be recoverable. For assets that are to be held and used, impairment is recognized when the estimated undiscounted cash flows associated with the asset or group of assets is less than their carrying value. If impairment exists, an adjustment is made to write the asset down to its fair value, and a loss is recorded as the difference between the carrying value and fair value. Fair values are determined based on quoted market values, discounted cash flows or internal and external appraisals, as applicable. Assets to be disposed of are carried at the lower of carrying value or estimated net realizable value. The Company decided to cease the use of a portion of its leased New York office space in 2022 and entered into two separate subleases agreements with third party subtenants, in which the sublease income is less than the original lease payments indicating impairment. In performing the recoverability test, the undiscounted future estimated cash flows and carrying value were identified for the subleased portion of the leased building, as an individual asset group, defined under ASC 360. A reduction to the carrying value of the ROU asset of $1,472 was recorded representing the carrying value amount in excess of the fair value with a corresponding impairment charge recorded to General and administrative in the Consolidated Statements of Operations for the year ended December 31, 2022. Business Combinations The Company applies the provisions of ASC 805, Business Combinations (“ASC 805”), in accounting for acquisitions. ASC 805 requires that the Company evaluates whether a transaction pertains to an acquisition of assets or to an acquisition of a business. A business is defined as an integrated set of assets and activities that is capable of being conducted and managed for the purpose of providing a return to investors. Asset acquisitions are accounted for by allocating the cost of the acquisition to the individual assets and liabilities assumed on a relative fair value basis; whereas the acquisition of a business requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as any contingent consideration, where applicable, the estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the business acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of a business acquisition’s measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations. Accounting for business combinations requires the Company to make significant estimates and assumptions, especially at the acquisition date, to determine the fair value of assets acquired and liabilities assumed, including the selection of valuation methodologies, estimates of future revenue and cash flows and discount rates in determining the fair value of intangible assets. Although the Company believes that the assumptions and estimates made in the past have been reasonable and appropriate, they are based in part on historical experience and information obtained from the management of the acquired companies and are inherently uncertain. Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates or actual results. The assets purchased and liabilities assumed have been reflected on the Company’s Consolidated Balance Sheets, and the results are included on the Consolidated Statements of Operations and Consolidated Statements of Cash Flows from the date of acquisition. Acquisition-related transaction costs, including legal and accounting fees and other external costs directly related to the acquisition, are recognized separately from the acquisition and expensed as incurred in General and administrative on the Consolidated Statements of Operations. In addition, uncertain tax positions and tax related valuation allowances assumed in a business combination are initially estimated as of the acquisition date. The Company reevaluates these items quarterly based upon facts and circumstances that existed as of the acquisition date with any adjustments to our preliminary estimates being recorded to goodwill if identified within the measurement period. Subsequent to the measurement period or the final determination of the tax allowance’s or contingency’s estimated value, whichever comes first, changes to these uncertain tax positions and tax related valuation allowances will affect the provision for income taxes in our consolidated statement of operations and could have a material impact on the results of operations and financial position. Goodwill and Indefinite-Lived Intangible Assets Goodwill is an asset representing the future economic benefit arising from other assets acquired in a business combination which are not individually identified and separately recognized. The Company does not amortize goodwill. Goodwill has resulted from the acquisition of Nanobox, Inc. (“Nanobox”) on April 4, 2019, Nimbella Corp. (“Nimbella”) on September 1, 2021, and Cloudways Ltd. (“Cloudways”) on September 1, 2022 as discussed in Note 3. Goodwill is reviewed for impairment on an annual basis as of October 1st of each year, or more frequently if a triggering event occurs. Goodwill was $315,168 and $32,170 as of December 31, 2022 and 2021, respectively, and reflects the excess of cost over fair market value of the identifiable assets of the company acquired. Indefinite-lived intangible assets consist of Internet Protocol (“IP”) addresses needed for customers to host their server online. The Company evaluates these indefinite-lived intangible assets for impairment on an annual basis as of October 1st of each year and whenever events or changes in circumstances indicate that an impairment may exist. Recoverability of assets held and used is measured by comparison of the carrying amount of an asset or an asset group to estimated undiscounted future net cash flows expected to be generated by the asset or asset group. If the carrying amount of an asset exceeds these estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the assets exceeds the fair value of the asset or asset group, based on discounted cash flows. No impairment charges for goodwill and indefinite-lived intangible assets have been recorded during the years ended December 31, 2022 and 2021. Intangible assets with indefinite lives were $44,821 and $39,906 as of December 31, 2022 and 2021, respectively, and are included as Intangible assets on the Consolidated Balance Sheets. Intangible Assets Intangible assets with definite lives consist of acquired developed technology. Intangible assets with definite lives are stated at cost less accumulated amortization and are amortized on a basis consistent with the timing and pattern of expected cash flows used to value the intangible, generally on a straight-line basis over the useful life of three Revenue Recognition The Company recognizes revenue in accordance with FASB Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”). The Company accounts for revenue using the following steps: 1. Identify the contract with a customer 2. Identify the performance obligations in the contract 3. Determine the transaction price 4. Allocate the transaction price to performance obligations in the contract 5. Recognize revenue when or as we satisfy a performance obligation The Company provides cloud computing services, including Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS), to its customers. The Company recognizes revenue based on the customer utilization of these resources. Customer contracts are typically month-to-month and do not include any minimum guaranteed quantities or fees. Fees are billed monthly, and payment is typically due upon invoicing. Revenue is recognized net of allowances for credits and any taxes collected from customers. The Company’s global cloud platform is supported by various third parties. The Company considered the principal versus agent guidance in ASC 606 and concluded that it is the principal for all services provided to its customers. The Company may offer sales incentives in the form of promotional and referral credits, and grant credits to encourage customers to use the Company’s services. These types of promotional and referral credits typically expire in two months or less if not used. For credits earned with a purchase, they are recorded as contract liabilities when earned and recognized at the earlier of redemption or expiration. The majority of credits are redeemed in the month they are earned. Timing of revenue recognition may differ from the timing of invoicing to the Company’s customers. The Company records a receivable when revenue is recognized prior to invoicing. Any payments received in advance of billing are a contract liability, which is recorded as Deferred revenue within Total current liabilities on the Consolidated Balance Sheets. Revenue recognized during the years ended December 31, 2022, 2021 and 2020, which was included in the Deferred revenue balances at the beginning of each respective period, was $2,894, $2,672 and $2,440, respectively. Cost of Revenue Cost of revenue consists primarily of fees related to operating in third-party co-location facilities, personnel expenses for those directly supporting our data centers and non-personnel costs, including amortization of capitalized internal-use software development costs and depreciation of our data center equipment. Third-party co-location facility costs include data center rental fees, power costs, maintenance fees, network and bandwidth. Personnel expenses include salaries, bonuses, benefits, and stock-based compensation. Research and Development Expenses Research and development expenses consist primarily of personnel costs including salaries, bonuses, benefits and stock-based compensation. Research and development expenses also include amortization of capitalized internal-use software development costs for research and development activities, which are amortized over three years, and professional services, as well as costs related to our efforts to add new features to our existing offerings, develop new offerings, and ensure the security, performance, and reliability of our global cloud platform. Sales and Marketing Expenses Sales and marketing expenses consist primarily of personnel costs of our sales, marketing and customer support employees including salaries, bonuses, benefits and stock-based compensation. Sales and marketing expenses also include costs for marketing programs, advertising and professional service fees. General and Administrative Expenses General and administrative expenses consist primarily of personnel costs of our human resources, legal, finance, and other administrative functions including salaries, bonuses, benefits, and stock-based compensation. General and administrative expenses also include provision for expected credit losses, software, payment processing fees, business insurance, depreciation and amortization expenses, rent and facilities costs, loss on sublease, and other administrative costs. Advertising and Other Promotional Costs Advertising and other promotional costs are expensed as incurred and are included in Sales and marketing on the Consolidated Statements of Operations. Non-direct response advertising expenses were $19,914, $14,577 and $6,331 for the years ended December 31, 2022, 2021 and 2020, respectively. Income Taxes The Company accounts for income taxes pursuant to the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future. Such deferred income tax assets and liabilities are based on enacted tax laws and rates applicable to periods in which the differences are expected to affect taxable income. A valuation allowance is established when necessary to reduce deferred tax assets to the amounts expected to be realized. Federal, state, and foreign income taxes are provided based on statutory rates. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law. The Tax Act requires an entity to make an accounting policy election of either (1) treating taxes due on future U.S. inclusions in taxable income related to Global Intangible Low Taxed Income (“GILTI”) as a current period expense when incurred (the “period cost method”) or (2) factoring such amounts into an entity’s measurement of its deferred taxes (the “deferred method”). The Company has elected to treat taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred using the period cost method. The Company accounts for uncertainty in income taxes using a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by the taxing authorities. The amount recognized is measured as the largest amount of benefit that has a greater than 50% likelihood of being realized upon ultimate audit settlement. The Company recognizes interest and penalties, if any, associated with income tax matters as part of income tax expense on the Consolidated Statements of Operations and includes accrued interest and penalties with the related income tax liability in Other current liabilities on the Consolidated Balance Sheets. Segment Information The Company’s chief operating decision maker, the chief executive officer, reviews discrete financial information presented on a consolidated basis for purposes of regularly making operating decisions, allocation of resources, and assessing financial performance. Accordingly, the Company has one operating and reporting segment. Geographical Information Revenue, as determined based on the billing address of the Company’s customers, was as follows: Year Ended December 31, 2022 2021 2020 North America 38 % 38 % 38 % Europe 30 % 30 % 30 % Asia 22 % 22 % 22 % Other 10 % 10 % 10 % Total 100 % 100 % 100 % Revenue derived from customers in the United States was 31% of total revenue for the years ended December 31, 2022, 2021 and 2020. No country outside of the United States had revenue greater than 10% of total consolidated revenue in any period presented. Long-lived assets includes property and equipment and operating leases. The geographic locations of the Company’s long-lived assets, net, based on physical location of the assets is as follows: December 31, 2022 2021 United States $ 206,118 $ 134,347 Singapore 60,307 23,520 Germany 50,274 28,824 Netherlands 35,951 26,979 Other 74,221 35,973 Total $ 426,871 $ 249,643 Concentration of Credit Risk The amounts reflected in the consolidated balance sheets for cash and cash equivalents, restricted cash, and trade accounts receivable are exposed to concentrations of credit risk. Although the Company maintains cash and cash equivalents with multiple financial institutions, the deposits, at times, may exceed federally insured limits. The Company believes that the financial institutions that hold its cash and cash equivalents are financially sound and, accordingly, minimal credit risk exists with respect to these balances. The Company’s customer base consists of a significant number of geographically dispersed customers. No customer represented 10% or more of accounts receivable, net as of December 31, 2022 and 2021. Additionally, no customer accounted for 10% or more of total revenue during the years ended De |
