−Removed: Customers generally enter into one-year renewable subscriptions though some customers do enter into subscriptions with longer terms.
−Removed: The subscription fee entitles the customer to an unlimited number of scans for a specified number of devices or web applications and, if requested by a customer as part of their subscription, a specified number of physical or virtual scanner appliances.
−Removed: Our physical and virtual scanner appliances are requested by certain customers as part of their subscriptions in order to scan IT infrastructures within their firewalls and do not function without, and are not sold separately from, subscriptions for our solutions.
−Removed: In some limited cases, we also provide certain computer equipment used to extend our Qualys Cloud Platform into our customers’ private cloud environment.
−Removed: Customers are required to return physical scanner appliances and computer equipment if they do not renew their subscriptions.
−Removed: We recognize revenues on a usage basis for certain other limited scan arrangements, where expiration dates can be extended.
−Removed: Physical equipment (scanners and private cloud platforms) are accounted for as operating leases under ASC 842.
−Removed: The company used the practical expedient to combine lease and nonlease components as a combined component under ASC 606 due to the software subscription nonlease components being the predominant component of the combined component.
−Removed: Therefore, the Company recognizes revenue for the physical equipment ratably over the related subscription period.
−Removed: Costs of shipping and handling charges associated with physical scanner appliances and other computer equipment are included in cost of revenues.
−Removed: Deferred r evenues consist of customer contracts billed or cash received that will be recognized in the future under subscriptions existing at the balance sheet date.
−Removed: We adopted ASC 606, "Revenue from Contracts with Customers" with a date of initial application of January 1, 2018.
−Removed: We adopted ASC 606 using the modified retrospective method and recognized the cumulative effect as an adjustment to the opening balance of equity at January 1, 2018.
−Removed: We previously expensed sales commission as incurred.
−Removed: Under ASC 606, sales commissions cost related to new business and upsells are recorded as an asset.
−Removed: We amortize the capitalized commission cost as a selling expense on a straight-line basis over a period of five years.

−Removed: The current and noncurrent portions of deferred commissions are included in prepaid expenses and other current assets, and other noncurrent assets, respectively, in our consolidated balance sheets.
+Added: We derive revenues from subscriptions that require customers to pay a fee in order to access our cloud solutions.
+Added: Contract period with customers generally ranges from less than a year to five years.  The subscription fee entitles the customer to an unlimited number of scans for a specified number of networked devices or web applications and, if requested by a customer as part of their subscription, a specified number of physical or virtual scanner appliances. Our physical and virtual scanner appliances are requested by certain customers as part of their subscriptions in order to scan IT infrastructures within their firewalls and do not function without, and are not sold separately from, subscriptions for our solutions.
+Added: In some limited cases, we also provide certain computer equipment used to extend our Qualys Cloud Platform into our customers’
+Added: private cloud environment.
+Added: Customers are required to return physical scanner appliances and computer equipment if they do not renew their subscriptions. 
+Added: In accordance with ASC 606 Revenue from Contracts with Customers ("ASC 606"), revenue is recognized when control of the subscription service is transferred to our customers in an amount that reflects the consideration we expect to be entitled to in exchange for those services.

+Added: In addition, we recognize revenues for certain limited scan arrangements on an as-used basis.
+Added: We recognize revenue related to professional services based on time and materials or completion of milestones stated in the contracts. When physical equipment are provided to the customers as part of the subscription service contract, we apply the practical expedient allowed under ASC 842 Leases to combine lease and nonlease components as a combined component to be accounted for under ASC 606, as we determined that the software subscription is the predominant component of the combined components. Therefore, we recognize revenue for the physical equipment ratably over the related subscription period. 
+Added: Incremental direct costs of obtaining a contract, which consist of sales commissions primarily for new business and upsells, are deferred and amortized over the estimated life of the customer relationship if renewals are expected and the renewal commission is not commensurate with the initial commission.
+Added: We elected the practical expedient to expense commissions on renewals where the specific anticipated contract term amortization period is one year or less.
+Added: We amortize the capitalized commission cost as a selling expense on a straight-line basis over a period of five years.

−Removed: Based on the analysis of positive and negative factors noted above, we do not have a valuation allowance against U.S.
−Removed: federal and certain state deferred tax assets.
−Removed: 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.
+Added: 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.
Accordingly, we continue to record a valuation allowance as of December 31, 2020 for our California deferred tax assets.
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.
+Added: W e do not have a valuation allowance against U.S.
+Added: federal and certain other state deferred tax assets.
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.
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
−Removed: all of the relevant facts.
+Added: 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.
It is inherently difficult and subjective to estimate such amounts, as this requires us to determine the probability of various possible settlement outcomes.

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, effectively settled issues under audit, the potential for interest and penalties, and new audit activity.
+Added: 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.
Such a change in recognition or measurement would result in recognition of a tax benefit or an additional charge to the tax provision.

−Removed: Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs materially from original estimates.
+Added: 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.
+Added: We assess these conditions on a quarterly basis.
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.
+Added: 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.
As a result, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future.
−Removed: 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.
Fair Value Measurement
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 other current 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, investments and derivative foreign currency forward contracts at fair value in accordance with the provisions of the authoritative accounting guidance that addresses fair value measurements.
+Added: 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.
+Added: 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.
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.
The hierarchy is broken down into three levels based on the reliability of inputs as follows:
−Removed: Level 1 —Valuations based on quoted prices in active markets for identical assets or liabilities.
−Removed: Level 2 —Valuations based on other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
−Removed: Level 3— 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: Our financial instruments consist of assets measured using Level 1 and 2 inputs.
−Removed: Level 1 assets include a highly liquid money market fund, which is valued using unadjusted quoted prices that are available in an active market for an identical asset.
−Removed: Level 2 assets include fixed-income U.S.
−Removed: government agency securities, commercial paper, corporate bonds, asset-backed securities and derivative financial instruments consisting of foreign currency forward contracts.
−Removed: The securities, bonds and commercial paper are valued using prices from independent pricing services based on quoted prices in active markets for similar instruments or on industry models using data inputs such as interest rates and prices that can be directly observed or corroborated in active markets.
−Removed: The foreign currency forward contracts are valued using observable inputs.
−Removed: The carrying amounts of other financial instruments including accounts receivable, the investments in a privately-held company, account payables, accrued liabilities in our consolidated balance sheets approximates fair value as of December 31, 2019 and 2018.
+Added: Level 1 - 
+Added: Valuations based on quoted prices in active markets for identical assets or liabilities.
+Added: Level 2 
+Added: - 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.
+Added: Level 3 - 
+Added: 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: Derivative Financial Instruments
−Removed: Derivative financial instruments are utilized by us to reduce foreign currency exchange risks.
−Removed: We use foreign currency forward contracts to mitigate the impact of foreign currency fluctuations of certain non-U.S.
−Removed: dollar denominated asset positions, to date primarily cash and accounts receivable (non-designated), as well as to manage foreign currency fluctuation risk related to forecasted transactions (designated).
−Removed: We account for these instruments as either non-designated or cash flow hedges, respectively.
−Removed: Open contracts are recorded within prepaid expenses and other current assets, other noncurrent assets, accrued liabilities or other noncurrent liabilities in the consolidated balance sheets.
−Removed: Gains and losses resulting from currency exchange rate movements on non-designated forward contracts are recognized in other income (expense).

+Added: We lease offices, our data center facilities and certain computer equipment under non-cancelable operating leases and finance leases.
+Added: On January 1, 2019, we adopted ASC 842 Leases using the current period adjustment method with an effective date of January 1, 2019.
+Added: 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.
+Added: The present value of the lease payments is calculated using the incremental borrowing rate of the underlying leases determined at lease commencement.
+Added: 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. 
+Added: 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.
+Added: For leases with a term of one year or less, we have elected not to record the right-of-use asset or liability.
