−Removed: activities are subject to local income tax and may also be subject to U.S.
−Removed: Income tax expense or benefit is recognized for the amount of taxes payable or refundable for the current year, and for deferred tax assets and liabilities for the tax consequences of events that have been recognized in an entity’s financial statements or tax returns.
−Removed: We must make significant assumptions, judgments and estimates to determine our current provision for (benefit from) income taxes, our deferred tax assets and liabilities, and any valuation allowance to be recorded against our deferred tax assets.
−Removed: Our judgments, assumptions and estimates relating to the current provision for (benefit from) income taxes include the geographic mix and amount of income (loss), our interpretation of current tax laws, and possible outcomes of current and future audits conducted by foreign and domestic tax authorities.
−Removed: Our judgments also include anticipating the tax positions we will record in the financial statements before actually preparing and filing the tax returns.
−Removed: Our estimates and assumptions may differ from the actual results as reflected in our income tax returns and we record the required adjustments when they are identified or resolved.
−Removed: Changes in our business, tax laws or our interpretation of tax laws, and developments in current and future tax audits, could significantly impact the amounts provided for income taxes in our results of operations, financial position, or cash flows.
−Removed: Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to tax benefit carry-forwards and to differences between the financial statement amounts of assets and liabilities and their respective tax basis.
−Removed: We regularly review our deferred tax assets for recoverability and establish a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized.
−Removed: To make this assessment, we take into account predictions of the amount and category of taxable income from available positive and negative evidence about these possible sources of taxable income.
−Removed: The weight given to the potential effect of negative and positive evidence is commensurate with the extent to which the strength of the evidence can be objectively verified.
−Removed: Based on the analysis of positive and negative factors noted above, we believe it is more likely than not that our California deferred tax assets will not be realized because the income attributed to California is not expected to be sufficient to recognize these deferred tax assets.
−Removed: Accordingly, we continue to record a valuation allowance as of December 31, 2020 for our California deferred tax assets.
−Removed: If, in the future, we determine that these deferred tax assets are more likely than not to be realized, a release of all or part, of the related valuation allowance could result in an income tax benefit in the period such determination is made.
−Removed: W e do not have a valuation allowance against U.S.
−Removed: federal and certain other state deferred tax assets.
−Removed: We recognize an income tax expense or benefit with respect to uncertain tax positions in our financial statements that we judge is more likely than not to be sustained solely on its technical merits in a tax audit, including resolution of any related appeals or litigation processes.
−Removed: To make this judgment, we must interpret complex and sometimes ambiguous tax laws, regulations and administrative practices.
−Removed: If an income tax position meets the more likely than not recognition threshold, then we must measure the amount of the tax benefit to be recognized by determining the largest amount of tax benefit that has a greater than a 50% likelihood of being realized upon effective settlement with a taxing authority that has full knowledge of all of the relevant facts.
−Removed: It is inherently difficult and subjective to estimate such amounts, as this requires us to determine the probability of various possible settlement outcomes.
−Removed: To determine if a tax position is effectively settled after a tax examination has been completed, we must also estimate the likelihood that another taxing authority could review the respective tax position.
+Added: Operating Activities
+Added: In 2021 , 
+Added: we generated $169.6 million of cash from our net income, as adjusted for non-cash items mainly related to stock-based compensation expense, depreciation and amortization expense and deferred taxes, as compared to $169.4 million in 2020.
+Added: In addition, we also generated $31.0 million of cash from working capital change in 2021, of which $37.4 million was related to net increase in deferred revenue and accounts receivable as a result of our continued growth in billing and collection, partially offset by higher prepaid income taxes of $6.9 million.
+Added: In 2020, we generated $10.7 million of cash from working capital change, which was also mainly related to deferred revenue and accounts receivable due to continued growth in billing and collection.
+Added: Investing Activities
+Added: In 2021, we used $4.5 million of cash in marketable securities investment, $24.4 million of cash in capital expenditures mainly related to computer equipment to support our growth and development and $1.1 million of cash to acquire certain technology assets, as compared to $49.8 million of cash used in marketable securities investment, $29.6 million of cash used in capital expenditures and $1.5 million of cash used for acquisition of technology assets in 2020.
+Added: Financing Activities
+Added: In 2021, we used $130.0 million of cash for share repurchase and $27.8 million of cash in payment of employee withholding taxes upon vesting of restricted stock units and received $50.0 million of proceeds from employee exercise of stock options, as compared to $126.7 million of cash used for share repurchase, $20.2 million of cash used in payment of employee withholding taxes upon vesting of restricted stock units and $34.5 million of cash received from employee exercise of stock options in 2020.
+Added: Net cash used in financing activities are expected to be higher in 2022 due to expected higher volume of share repurchase and lower cash receipt from stock option exercise, mainly due to the resignation of our former CEO.
+Added: We believe our existing cash and cash equivalents, marketable securities and our expected cash flow generated from operations will be sufficient to fund our operations for the next twelve months and beyond.
+Added: We do not anticipate that we will need funds generated from foreign operations to fund our domestic operations.
+Added: However, if we repatriate these funds, we could be subject to foreign withholding taxes.
+Added: Our material cash requirements mainly include the following contractual and other obligations:
+Added: Our operating lease obligations to make payments under our non-cancelable lease agreements for our facilities and data centers.
+Added: We had fixed operating lease payment obligations of $54.2 million as of December 31, 2021, with $14.5 million expected to be paid within the next 12 months.
+Added: Cash outflow for capital expenditures in 2022 is expected to be in a range of $25.0 million to $30.0 million.
+Added: Our future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our sales and marketing activities, the timing, type and extent of our spending on research and development efforts, international expansion and investment in data centers and cloud infrastructures.
+Added: We may also seek to invest in or acquire complementary businesses or technologies.
+Added: Other non-cancelable purchase obligations related to cloud infrastructures and other service providers totaled $36.4 million, of which $16.4 million is expected to be paid with in the next 12 months.
+Added: We expect to continue to use cash to repurchase shares in 2022 under our share repurchase program authorized by our board of directors on February 5, 2018.
+Added: As of December 31, 2021, our board of directors had authorized an aggregate amount of $700.0 million for repurchases under our share repurchase program, of which approximately $271.8 million remained available.
+Added: Shares will be repurchased from time to time on the open market in accordance with Rule 10b-18 of the Exchange Act of 1934, including pursuant to a pre-set trading plan adopted in accordance with Rule 10b5-1 under the Exchange Act.
+Added: Critical Accounting Estimates
+Added: The preparation of our consolidated financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures.
+Added: Our significant accounting policies are described in Note 1 - The Company and Summary of Significant Accounting Policies in the accompanying notes to the consolidated financial statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Annual Report on Form 10-K.
+Added: On an ongoing basis, we evaluate our estimates and assumptions based on historical and anticipated results and trends that we believe represent our best estimate under the circumstances.
+Added: However, as accounting estimates are subject to inherent uncertainty, our actual results may differ from these estimates under different assumptions or conditions.
+Added: Significant assumptions, judgments and estimates are involved in determining our provision for (benefit from) income taxes, our deferred tax assets and liabilities, and any valuation allowance to be recorded against our deferred tax assets.
+Added: Our judgments, assumptions and estimates relating to the current provision for income taxes include the geographic mix and amount of income (loss), our interpretation of current tax laws, and possible outcomes of current and future audits conducted by foreign and domestic tax authorities.
+Added: Our judgments also include anticipating the tax positions we will record in the financial statements before preparing and filing the tax returns.
+Added: Our estimates and assumptions may differ from the actual results as reflected in our income tax returns and we record the required adjustments when they are identified or resolved. Changes in our business and tax laws or our interpretation of those, and developments in current and future tax audits, could significantly impact the amounts provided for income taxes in our results of operations, financial position, or cash flows.
+Added: The assessment of tax effects of our uncertain tax positions in our financial statements involves significant judgment in interpreting complex and ambiguous tax laws, regulations, and administrative practices, determining the probability of various possible settlement outcomes, evaluating the litigation process based on tax authority behaviors in similar cases, and estimating the likelihood that another taxing authority could review the respective tax position.
+Added: These judgments are inherently challenging and subjective because a taxing authority may change its behavior at any time.
We must also determine when it is reasonably possible that the amount of unrecognized tax benefits will significantly increase or decrease in the 12 months after each fiscal year-end.
−Removed: These judgments are difficult because a taxing authority may change its behavior as a result of our disclosures in our financial statements.
−Removed: We must reevaluate our income tax positions on a quarterly basis to consider factors such as changes in facts or circumstances, changes in tax laws, effectively settled issues under audit, the potential for interest and penalties, and new audit activity.
+Added: We reevaluate our income tax positions on a quarterly basis to consider factors such as changes in facts or circumstances, changes in tax laws, effectively settled issues under audit, the potential for interest and penalties, and new audit activity.
Such a change in recognition or measurement would result in recognition of a tax benefit or an additional charge to the tax provision.
Stock-Based Compensation
−Removed: We recognize the fair value of our employee stock options and restricted stock units over the requisite service period for those awards ultimately expected to vest.
−Removed: The fair value of each option is estimated on date of grant using the Black-Scholes-Merton option pricing model and the fair value of each restricted stock unit is based on the fair value of our stock on the date of grant.
−Removed: Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs materially from original estimates. For performance-based non-qualified stock options and restricted stock units, we recognize compensation costs when it is probable that the performance conditions will be met.
−Removed: We assess these conditions on a quarterly basis.
−Removed: Determining the appropriate fair value model and calculating the fair value of employee stock options requires the use of highly subjective assumptions, including the expected life of the stock option and stock price volatility.
−Removed: The assumptions used in calculating the fair value of employee stock options represent management’s best estimates, but the estimates involve inherent uncertainties and the application of management’s judgment.
−Removed: As a result, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future.
−Removed: Fair Value Measurement
−Removed: Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
−Removed: For certain of our financial instruments, including cash and certain cash equivalents, accounts receivable, accounts payable and accrued liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these balances.
−Removed: We measure and report certain cash equivalents, marketable securities and derivative foreign currency forward contracts at fair value in accordance with the provisions of the authoritative accounting guidance that addresses fair value measurements.
−Removed: This guidance establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available.
−Removed: The hierarchy is broken down into three levels based on the reliability of inputs as follows:
−Removed: Level 1 - 
−Removed: Valuations based on quoted prices in active markets for identical assets or liabilities.
−Removed: Level 2 
−Removed: - Valuations based on other than quoted prices in active markets for identical assets and liabilities, including quoted prices for identical assets or liabilities in less active or inactive markets, quoted prices for similar assets or liabilities in active markets, or inputs other than quoted prices that are observable for substantially the full term of the assets or liabilities.
−Removed: Level 3 - 
−Removed: Valuations based on inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability.
−Removed: For further details, see Part II, Item 8 of this Annual Report on Form10-K Note 2, Fair Value of Financial Instruments.
−Removed: We lease offices, our data center facilities and certain computer equipment under non-cancelable operating leases and finance leases.
−Removed: On January 1, 2019, we adopted ASC 842 Leases using the current period adjustment method with an effective date of January 1, 2019.
−Removed: For both operating and finance leases, we recognize a right-of-use asset, which represents our right to use the underlying asset for the lease term, and a lease liability, which represents the present value of our obligation to make payments arising over the lease term. Many of our leases include rental escalation clauses, renewal options and/or termination options that are factored into our determination of lease payments and lease terms when appropriate.
−Removed: The present value of the lease payments is calculated using the incremental borrowing rate of the underlying leases determined at lease commencement.
−Removed: As most of our leases do not provide a readily determinable implicit rate, we determine an incremental borrowing rate using a portfolio approach based on the rate of interest that the Company would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term as the leases. 
−Removed: Where we are the lessee, we elect to account for non-lease components associated with our leases (e.g., common area maintenance costs) and lease components separately for substantially all of our asset classes, except for data centers, for which we elected to combine lease and non-lease components.
−Removed: For leases with a term of one year or less, we have elected not to record the right-of-use asset or liability.
+Added: We recognize the fair value of our employee stock options and restricted stock units, including performance-based restricted stock units, over the requisite service period.
+Added: The fair value of each stock option is estimated on date of grant using the Black-Scholes-Merton option pricing model.
+Added: Determining the appropriate fair value model and calculating the fair value of employee stock options requires the use of subjective assumptions, including the expected life of the stock option and stock price volatility.
+Added: The recognition of expenses for performance based restricted stock units requires us to estimate the probability that the performance condition will be achieved and the number of awards that will vest are adjusted accordingly at each reporting period.
+Added: The assumptions used in calculating the fair value of employee stock options and estimating the probability of achievement of performance metrics represent management’s best estimates, which require significant judgment and involve inherent uncertainties.
+Added: While not material to the current year, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future.
