--------------------------------------------------------------------------------
Table of Contents Overview We are a leading semiconductor company that designs, develops and markets high-performance power solutions. Incorporated in 1997, our core strengths include deep system-level and applications knowledge, strong analog design expertise and innovative proprietary process technologies. These combined strengths enable us to deliver highly integrated monolithic products that offer energy-efficient, cost-effective, easy-to-use solutions for systems found in computing and storage, automotive, industrial, communications and consumer applications. Our mission is to reduce total energy consumption in our customers' systems with green, practical and compact solutions. We believe that we differentiate ourselves by offering solutions that are more highly integrated, smaller in size, more energy-efficient, more accurate with respect to performance specifications and, consequently, more cost-effective than many competing solutions. We plan to continue to introduce new products within our existing product families, as well as in new innovative product categories. We operate in the cyclical semiconductor industry where there is seasonal demand for certain products. We are not immune from current and future industry downturns, but we have targeted product and market areas that we believe have the ability to offer above average industry performance over the long term.
We work with third parties to manufacture and assemble our ICs. This has enabled us to limit our capital expenditures and fixed costs, while focusing our engineering and design resources on our core strengths.
Following the introduction of a product, our sales cycle generally takes a number of quarters after we receive an initial customer order for a new product to ramp up. Typical lead times for orders are generally 16 to 26 weeks. These factors, combined with the fact that orders in the semiconductor industry can typically be cancelled or rescheduled without significant penalty to the customer, make the forecasting of our orders and revenue difficult. We derive most of our revenue from sales through distribution arrangements and direct sales to customers inAsia , where our products are incorporated into end-user products. Our revenue from direct or indirect sales to customers inAsia was 89% and 90% for the three months endedMarch 31, 2021 and 2020, respectively. We derive a majority of our revenue from the sales of our DC to DC converter products which serve the computing and storage, automotive, industrial, communications and consumer markets. We believe our ability to achieve revenue growth will depend, in part, on our ability to develop new products, enter new market segments, gain market share, manage litigation risk, diversify our customer base and continue to secure manufacturing capacity.
Impact of COVID-19 on Our Business
Our primary focus is to continue to execute our business plan and mitigate the effect of the COVID-19 pandemic on our financial position and operations, while actively taking all necessary precautions to ensure the safety of our employees, our suppliers and our customers. The pandemic did not materially and adversely impact our overall operating results or business operations during the three months endedMarch 31, 2021 . Some of the key developments and initiatives we implemented since the outbreak of the COVID-19 pandemic inMarch 2020 include, but are not limited to, the following:
? Employees:
Our top priority during the pandemic is protecting the health and safety of our
employees. As governments continue to institute new guidelines on commercial
operations, we continue to monitor new developments and work to ensure our
compliance while also maintaining business continuity for essential operations.
In the
work-from-home arrangements in accordance with local regulations. To date, we
believe these arrangements have contributed to the health and safety of our
employees and allowed us to successfully maintain business operations and
customer relations.
? Facilities and Supply Chain:
Our manufacturing facilities in
operational and have experienced minimal disruptions, as we continue to follow
the proper guidance issued by governmental authorities. In addition, we have
not experienced any major supply chain disruptions as a result of the pandemic.
? Customers:
Overall, we did not experience an adverse impact on customer demand during the
first quarter of 2021 as a result of the pandemic. Our revenue increased in all
of our end markets compared to the same period in 2020. Furthermore, there were
no significant delays in payments by our customers. However, we cannot provide
assurance that we will not experience a material and adverse impact on customer
demand for the remainder of 2021 as a result of the pandemic. 24

? Liquidity and Capital Resources:
Our cash and investment balances remain strong and we continue to generate
positive operating cash flows. We believe we have sufficient liquidity to
satisfy our cash needs as we manage through the current uncertain environment.
However, we will continue to monitor, evaluate and take action, as necessary,
to preserve adequate liquidity to support our business for the remainder of
2021. We are actively working with our stakeholders, including customers, suppliers and employees, to address the impact of the pandemic. We will continue to monitor the situation, to assess further possible implications to our business, supply chain and customers, and to take actions in an effort to mitigate adverse consequences. However, we cannot reasonably estimate the duration and severity of the pandemic or its ultimate impact on the global economy, the semiconductor industry and our business. A prolonged economic slowdown as a result of the pandemic could materially and adversely impact our business, results of operations and financial condition for the remainder 2021 and beyond.
Cybersecurity Risk Management
We are committed to protecting our information technology ("IT") assets, including computers, systems, corporate networks and sensitive data, from unauthorized access or attack. We have established an internal global IT policy handbook as well as IT security management control procedures designed to cover the following key areas:
? Create information security awareness and define responsibilities among our
employees and business partners; ? Implement controls to identify IT risks and monitor the use of our systems and
information resources; ? Establish key policies and processes to adequately and timely respond to
security threats; ? Maintain disaster recovery and business continuity plans; and ? Ensure compliance with applicable laws and regulations regarding the management
of information security. We require all new employees to attend an IT security training orientation. In addition, on an as-needed basis, our IT team provides trainings and updates to employees related to our policies and procedures. OurIT Steering Committee , which consists of our senior management and IT team, meets on a regular basis to review initiatives and projects to improve IT security, as well as resources and budgets for our cybersecurity compliance and education efforts. Our Audit Committee of the Board of Directors, which consists of three independent members, is responsible for the oversight of our cybersecurity risk program. On a regular basis, the Audit Committee reviews reports and updates from our Chief Financial Officer about major risk exposures, their potential impact on our business operations, and management's strategies to assess, monitor and mitigate those risks. The Audit Committee also provides updates of their oversight and findings to the Board of Directors. We believe we have adequate resources and sufficient policies, procedures and oversight in place to identify and manage our IT security risks to our business operations. To date, we have not experienced any material information security breaches or incurred significant operating expenses related to information security breaches.
Critical Accounting Policies and Estimates
In preparing our condensed consolidated financial statements in accordance with GAAP, we are required to make estimates, assumptions and judgments that affect the amounts reported in our financial statements and the accompanying disclosures. Estimates and judgments used in the preparation of our condensed consolidated financial statements are, by their nature, uncertain and unpredictable, and depend upon, among other things, many factors outside of our control, including demand for our products, economic conditions and other current and future events, such as the impact of the COVID-19 pandemic. As of the date of issuance of these condensed consolidated financial statements, we are not aware of any specific event or circumstance that would require our management to update the significant estimates and assumptions used in the preparation of the condensed consolidated financial statements, as compared to those disclosed in the Annual Report on Form 10-K for the year endedDecember 31, 2020 . As new events continue to evolve and additional information becomes available, any changes to these estimates and assumptions will be recognized in the condensed consolidated financial statements as soon as they become known. Actual results could differ from these estimates and assumptions, and any such differences may be material to our condensed consolidated financial statements. Results of Operations

Our R&D headcount was 909 employees as ofMarch 31, 2021 , compared with 837 employees as ofMarch 31, 2020 .
Selling, General and Administrative ("SG&A")
SG&A expenses primarily include salary and benefit expenses, bonuses, stock-based compensation and deferred compensation for sales, marketing and administrative personnel, sales commissions, travel expenses, facilities costs, and professional service fees.
Three Months Ended March 31, 2021 2020 Change (in thousands, except percentages) SG&A expenses$ 51,453 $ 32,164 60.0 % As a percentage of revenue 20.2 % 19.4 % SG&A expenses were$51.5 million , or 20.2% of revenue, for the three months endedMarch 31, 2021 , and$32.2 million , or 19.4% of revenue, for the three months endedMarch 31, 2020 . The$19.3 million increase in SG&A expenses was primarily due to an increase of$8.0 million in stock-based compensation expenses, which were mainly associated with performance-based equity awards, an increase of$5.3 million in cash compensation expenses, which include salary, benefits and bonuses, an increase of$2.8 million in expenses related to changes in the value of the deferred compensation plan liabilities, and an increase of$1.6 million in commission expenses driven by higher revenue. Our SG&A headcount was 585 employees as ofMarch 31, 2021 , compared with 513 employees as ofMarch 31, 2020 . Litigation Expense Litigation expense was$1.6 million for the three months endedMarch 31, 2021 , compared with$2.3 million for the three months endedMarch 31, 2020 . The decrease was due to a decrease in litigation activity related to ongoing patent infringement and other matters. Other Income (Expense), Net Other income, net, was$2.6 million for the three months endedMarch 31, 2021 , compared with other expense, net, of$1.7 million for the three months endedMarch 31, 2020 . The increase was primarily due to an increase of$4.9 million in income related to changes in the value of the deferred compensation plan investments, which was partially offset by an increase of$0.3 million in amortization of the premium on available-for-sale securities. Income Tax Expense (Benefit) The income tax provision or benefit for interim periods is generally determined using an estimate of our annual effective tax rate and adjusted for discrete items, if any, in the relevant period. Each quarter the estimate of the annual effective tax rate is updated, and if our estimated tax rate changes, a cumulative adjustment is made. The income tax expense for the three months endedMarch 31, 2021 was$3.3 million , or 6.7% of pre-tax income. The effective tax rate differed from the federal statutory rate primarily due to foreign income from our subsidiaries inBermuda andChina being taxed at lower statutory tax rates, and excess tax benefits from stock-based compensation. The decrease in the effective tax rate relative to the federal statutory rate was partially offset by the inclusion of the GILTI tax. The income tax benefit for the three months endedMarch 31, 2020 was$6.5 million , or 22.2% of pre-tax income. The effective tax rate differed from the federal statutory rate primarily due to excess tax benefits from stock-based compensation, and foreign income from our subsidiaries inBermuda andChina being taxed at lower statutory tax rates. The decrease in the effective tax rate relative to the federal statutory rate was partially offset by the inclusion of the GILTI tax. 27
