Our net revenues were $703.3 million, $488.3 million and $420.7 million in 2021, 2020 and 2019, respectively.

In 2021, revenues increased by $215.0 million, reflecting the strong demand conditions currently prevalent across the semiconductor industry, as well as market-share gains for our products in a broad range of applications including consumer appliances, advanced chargers for mobile devices such as smartphones, tablets and notebook computers, and a range of industrial applications including home-and-building automation, electronic utility meters, battery-operated tools and broad-based industrial applications.

We believe that a variety of factors contributed to our ability to gain market share during the year, including:

stricter energy-efficiency standards implemented in China for air conditioners;

our superior product availability and delivery performance relative to many competitors whose lead times have extended much more than ours have;

and the fact that our products require a smaller number of external components compared to competing solutions, as many such components have been in short supply.

In 2020, revenues increased by $67.6 million due to growth across all end markets reflecting increased adoption of higher-power chargers for mobile phones and tablets, increased sales for desktop computers and monitors, as well as a broad range of industrial and consumer-appliance applications.

In 2019, revenues increased by $4.7 million due to growth in sales into the communications end-market, reflecting increased adoption of faster, higher-power chargers for mobile phones;

this trend has resulted in both unit growth and higher average selling prices for our products in this market.

Growth in revenues from the communications end-market was largely offset by lower sales into the consumer and industrial markets, primarily reflecting macroeconomic, cyclical and trade-related factors that have affected the broader semiconductor industry.

Our top ten customers, including distributors that resell to OEMs and merchant power supply manufacturers, accounted for approximately 78%, 62% and 54% of net revenues in 2021, 2020 and 2019, respectively.

In 2020, two customers, distributors of our products, accounted for approximately 19% and 11% of net revenues.

In 2019 and 2018, one of these customers accounted for approximately 11% and 14% of net revenues.

In 2021 and 2020, t wo customers, which are distributors of our products, each accounted for more than 10% of our net revenues.

In 2019, one of these customers accounted for more than 10% of our net revenues.

International sales represented approximately 98%, 98% and 97% of net revenues in 2021, 2020 and 2019, respectively.

this sensitivity may increase or decrease depending on the percentage of our wafer supply that we purchase from Japanese suppliers.

Also, although our wafer fabrication and assembly operations are outsourced, as are most of our test operations, a portion of our production costs are fixed in nature.

although our wafer fabrication and assembly operations are outsourced, as are most of our test operations, a portion of our production costs are fixed in nature.

As a result, our unit costs and gross profit margin are impacted by the volume of units we produce.

Our gross profit, defined as net revenues less cost of revenues, was $360.6 million or 51% of net revenues in 2021, compared to $243.6 million or 50% of net revenues in 2020, and $213.4 million or 51% of net revenues in 2019.

Our gross margin decreased in 2020 due primarily to an unfavorable change in end-market mix with a greater amount of revenues coming from lower-margin end markets .

Our gross margin decreased in 2019 primarily due to increased wafer substrate costs.

Total operating expenses in 2020 were $173.1 million, compared to a net gain of $3.6 million in 2019 stemming from the $169.0 million gain on settlement of our litigation with ON Semiconductor.

In 2018, total operating expenses were $159.1 million.

Apart from the effects of the 2019 legal settlement, the increase in operating expenses in 2020 was due primarily to higher stock-based compensation expense related mainly to performance-based awards, along with higher salary and related expenses from annual merit increases and the expansion of our workforce.

Our gross margin increased slightly in 2021 as manufacturing efficiencies were mostly offset by an unfavorable change in end-market mix .

Our gross margin decreased in 2020, as compared to 2019, due to an unfavorable change in end-market mix with a greater amount of revenues coming from lower-margin end markets .

Total operating expenses in 2021 were $185.6 million, an increase of $12.5 million as compared to 2020 due to higher salary and related expenses driven by increased headcount and annual merit increases, increased commission expense driven by increased sales and higher stock-based compensation expense related to performance-based awards .

These increases were partially offset by lower patent-litigation expenses.

other locations around the world have also been subject to such restrictions.

We will begin a phased reopening of our San Jose headquarters when these restrictions are lifted.

Some of our employees in other locations around the world have returned to the office under a phased reopening plan.

This work from home status continued for many of our employees throughout 2021 and into 2022.

Our employee health and well-being are top priorities.

We are actively monitoring the evolving situation and expect most employees to return to the office when circumstances improve and restrictions are further lifted.

We have implemented a variety of measures to protect the health and safety of our employees, including the provision of masks, gloves and sanitizers, social-distancing rules, and regular deep cleaning of our facilities.

While we have been able to conduct our day-to-day operations effectively in spite of the restrictions caused by the pandemic, the pandemic has caused disruptions in our supply chain.

While the supply of wafers from our foundry partners has not been interrupted, government-mandated closures in China, Malaysia, Sri Lanka and the Philippines in the early stages of the pandemic caused temporary shutdowns at our assembly and test sub-contractors in those countries.

All of the affected sub-contractors have now resumed operations.

While these disruptions resulted in delayed shipments to some customers, our results were not materially affected due to a variety of mitigation measures including higher-than-normal inventories of wafers and finished goods, safety stocks of certain key inputs, and multiple sources for components for most of our products.

Despite the economic downturn stemming from the pandemic, demand for goods incorporating our products is strong.

While the future trajectory of demand is highly uncertain, we believe our business is fundamentally sound with strong, long-term growth prospects.

We have not reduced headcount and intend to continue investing in research and development and other functions necessary to support our future growth.

While our supply of wafers from our foundry partners has not been interrupted, government-mandated closures in China, Malaysia, Sri Lanka and the Philippines have caused temporary shutdowns at our assembly and test sub-contractors at various times.

These disruptions have not materially affected our results due to a variety of mitigation measures including higher-than-normal inventories of wafers and finished goods in the early stages of the pandemic, safety stocks of certain key inputs, and multiple sources for components for most of our products.

Although there are signs of improvement in many areas around the world, the potential for new lockdowns and other mitigation efforts to deal with an increase in infection rates due to the emergence of the omicron variant in certain areas remains a key risk for our supply chain and the results of our business.

While the continuing pandemic brings a greater-than-normal level of uncertainty with respect to the demand for our products, we believe our business is fundamentally sound with strong, long-term growth prospects.

We have increased headcount and intend to continue investing in research and development and other functions necessary to support our future growth.

Product revenues consist of sales to original equipment manufacturers, or OEMs, merchant power supply manufacturers and distributors.

Approximately 75% of our net product sales were made to distributors in 2020.

We apply the provisions of Accounting Standards Codification (ASC) 606-10, Revenue from Contracts with Customers , and all related appropriate guidance.

(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 the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.

Product revenues consist of sales to original equipment manufacturers, or OEMs, merchant power supply manufacturers and distributors.

We consider customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer.

In situations where sales are to a distributor, we have concluded that our contracts are with the distributor as we hold contracts bearing enforceable rights and obligations with only the distributor.

As part of our consideration of the contract, we evaluate certain factors including the customer’s ability to pay (or credit risk).

For each contract, we consider the promise to transfer products, each of which is distinct, to be the identified performance obligations.

In determining the transaction price we evaluate whether the price is subject to refund or adjustment to determine the net consideration to which we expect to be entitled.

As our standard payment terms are less than one year, we elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component.

We allocate the transaction price to each distinct product based on their relative standalone selling price.

We consider the product price as specified on the purchase order the standalone selling price as it is an observable input which depicts the price as if sold to a similar customer in similar circumstances.

We recognize revenue when control of the product is transferred to the customer (i.e., when our performance obligation is satisfied), which typically occurs at shipment.

Further, in determining whether control has transferred, we consider if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer.

Frequently, we receive orders for products to be delivered over multiple dates that may extend across several reporting periods.

We invoice for each delivery upon shipment and recognize revenue for each distinct product delivered, assuming transfer of control has occurred.

As scheduled delivery dates are within one year, under the optional exemption provided by ASC 606-10-50-14 revenues allocated to future shipments of partially completed contracts are not disclosed.

We have also elected the practical expedient under ASC 340-40-25-4 to expense commissions when incurred as the amortization period of the commission asset we would have otherwise recognized is less than one year.

Sales to international customers that are shipped from our facility outside of the United States are pursuant to EX Works, or EXW, shipping terms, meaning that control of the product transfers to the customer upon shipment from our foreign warehouse.

Sales to international customers that we ship from our facility in California are pursuant to Delivered at Frontier, or DAF, shipping terms.

As such, control of the product passes to the customer when the shipment reaches the destination country and we recognize revenue upon the arrival of the product in that country.

Shipments to customers in the Americas are pursuant to Free on Board, or FOB, point of origin shipping terms meaning that we pass control to the customer upon shipment.

Sales to most distributors are made under terms allowing certain price adjustments and limited rights of return (known as “stock rotation”) of our products held in their inventory or upon sale to their end customers.

In determining the transaction price, we consider ship and debit price adjustments to be variable consideration.

Such price adjustments are estimated using the expected value method based on an analysis of actual ship and debit claims, at the distributor and product level, over a period of time considered adequate

to account for current pricing and business trends.

Historically, actual price adjustments for ship and debit claims relative to those estimated and included when determining the transaction price have not materially differed.

At the time revenue is recognized on sales to distributors, future ship and debit price adjustments are unknown and therefore subject to uncertainty.

The reserve for ship and debit claims increased by $15.2 million between December 31, 2020 and December 31, 2021, primarily due to higher inventory levels held by distributors and expected ship and debit claims related to such inventory.

Historically, actual price adjustments for ship and debit claims relative to those estimated when determining the transaction price have not materially differed.

To the extent future ship and debit claims significantly exceed amounts estimated, there could be a material impact on our revenues and results of operations.

Stock rotation rights grant the distributor the ability to return certain specified amounts of inventory.

Stock rotation adjustments are an additional form of variable consideration and are also estimated using the expected value method based on historical return rates.

Historically, these distributor stock rotation adjustments have not been material.

Sales to certain distributors are made under terms that do not include rights of return or price concessions after the product is shipped to the distributor.

Accordingly, upon application of steps one through five above, product revenue is recognized upon shipment and transfer of control.

We generally provide an assurance warranty that our products will substantially conform to the published specifications for twelve months from the date of shipment.

Our liability is limited to either a credit equal to the purchase price or replacement of the defective part.

Returns under warranty have historically been immaterial.

As such, we do not record a specific warranty reserve or consider activities related to such warranty, if any, to be a separate performance obligation.

We account for income taxes under the provisions of ASC 740, Income Taxes .

Under the provisions of ASC 740, deferred tax assets and liabilities are recognized based on the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, utilizing the tax rates that are expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

We recognize valuation allowances to reduce any deferred tax assets to the amount that we estimate will more likely than not be realized based on available evidence and management’s judgment.

In the event that we determine, based on available evidence and management judgment, that all or part of the net deferred tax assets will not be realized in the future, we would record a valuation allowance in the period the determination is made.

In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws.

Resolution of these uncertainties in a manner inconsistent with our expectations could have a material impact on our results of operations and financial position.

As of December 31, 2020, we continue to maintain a valuation allowance on our California, New Jersey and Canada deferred tax assets as we believe that it is not more likely than not that the deferred tax assets will be fully realized.

Stock rotation returns are an additional form of variable consideration and are also estimated using the expected value method based on historical return rates.

Historically, these distributor stock rotation returns have not been material.
