In addition, a webcast replay of today's call, along with a transcript will be available shortly on the Investor Relations page of our website. Let me begin this afternoon's discussion by providing some color regarding my decision to step down as Vicor's Chief Financial Officer, effective June 30, 2021. As noted in today's press release, I have informed Patrizio and the Board of my intent to pursue other interests and different types of challenges during the next phase of my career. I've had a remarkable run as CFO of Vicor, but I feel the time is right for me to look for other opportunities and forms of personal enrichment. As stated, we have kicked off a search for our next CFO, and I will be focused on a smooth transition to the leadership of my successor. I will be leaving behind a highly talented team, a strong balance sheet and a clear road map for future success. Now, I'll turn to a review of our Q4 financial performance, after which Phil will review recent market developments. And Patrizio, Phil and I will take your questions. In my remarks, I will focus mostly on the sequential quarterly change for the P&L and balance sheet items and refer you to our press release or our upcoming Form 10-K for year-over-year comparisons. As stated in today's press release, Vicor recorded total revenue for the fourth quarter of $84.3 million, up 7.9% from the third quarter total of $78.1 million. For the full year, 2020 revenue totaled $296.6 million, up 12.8% from $263 million for 2019. Quarterly Advanced Products revenue rose 10.4% sequentially, reflecting the continued ramp of shipments of our lateral power solutions for AI acceleration, demand for our 48-volt direct to CPU Solutions, and the first volume shipments of our new satellite solutions. Brick product revenue rose 6.1% sequentially, reflecting a broad resumption of shipments to our North American customers after the pandemic-related trough of the second and third quarters. This increase offset a sequential decline in shipments to China with those export volumes of brick products returning to trend from Q3's high level. Shipments to stocking distributors also rose sequentially. Turns volume was essentially unchanged sequentially. For the full year, Advanced Products revenue for 2020 totaled $106.1 million, up 41.5% from $75 million for 2019, while Brick Products revenue for 2020 totaled $190.3 million, up 1.3% from $187.8 million for 2019. Exports for the fourth quarter declined sequentially as a percentage of total revenue to approximately 64% of consolidated revenue from the prior quarter's 73%, reflecting the factors just mentioned regarding North American and Chinese shipments. For the full year, exports increased 35% and represented 64.4% of total revenue. For Q4, Advanced Products share of total revenue rose for the fifth consecutive quarter to 40%, with Brick Products share correspondingly declining to 60% of total revenue. We believe Advanced Products sales will expand further as a percentage of total revenues, especially once new manufacturing capacity comes online, given the high-growth segments we are targeting with our 48-volt technology, including AI, data center and automotive, in contrast to the mature growth of the segments we serve with Brick Products. Turning to Q4 gross margin, we recorded a consolidated gross profit margin of 48%, an increase of 5 points compared to the margins reported for Q2 and Q3. Higher volumes and improved mix contributed to higher profitability as did a reduction in cost variances. Gross margin dollars rose 21% sequentially. Margins remain under some pressure of high tariff charges, which totaled $1.5 million, representing approximately 1.8 margin points for the whole quarter. We did see a reduction in quarterly tariffs as Q4's total was 18% lower sequentially, in part, reflecting our ongoing efforts to reduce component imports from China. We expect to see further improvement through 2021. I'll now turn to Q4 OpEx, which rose just under 6% sequentially, but were consistent with longer-term trend, reflecting periodic swings in discretionary spending. The amounts of total equity-based compensation expense for Q4, included in cost of goods, SG&A and R&D were approximately $242,000, $851,000 and $504,000, respectively, totaling $1.6 million. For Q4, we recorded operating income of $11.6 million, representing an operating margin of 13.8%. The sequential 90% increase in operating income reflects the operational leverage in our model. Turning to income taxes. We recorded a net provision for Q4 of $788,000, representing an effective tax rate for the quarter of 7%. Net income attributable to Vicor for Q4 totaled $11.2 million. GAAP diluted earnings per share was $0.25 based on a fully diluted share count of 44,772,000 shares. For the year, net income attributable to Vicor totaled $17.9 million, representing diluted EPS of $0.41, up from the prior year's $0.34. Before I turn to our financial position, a few words about COVID-19 and our workforce. Beginning in Q1, Vicor took substantial steps to protect the health and safety of our employees following federal and local guidelines for employee well-being. As a designated essential manufacturer using masks and practicing social distancing from the onset of the pandemic, we have continuously operated 3 shifts at our Andover manufacturing facility. With only a few exceptions, our engineering sales and administrative personnel returned to their offices in early Q2. I refer listeners to our Q3 2020 10-Q filing, which sets forth details regarding our response to the pandemic and the impact it has on our operations through September 30, 2020. As is well known, coronavirus infections rose domestically during the fourth quarter, and the daily total of reported infections only has begun to decline in the past few weeks. Vicor experienced higher absenteeism from December through January, largely the consequence of quarantine requirements. However, our ability to adjust shift staffing in the factory, allowed us to avoid meaningful disruption of production schedules, and we hope the worst is behind us, as absenteeism has recently returned to low levels. Nevertheless, because of the potential influence of the COVID-19 pandemic is associated with risks outside of our control, we cannot estimate the extent of such influence on our financial or operational performance or when such influence might occur. Turning to our cash flow and balance sheet. Cash, cash equivalents and short-term investments totaled $212 million, a sequential increase of 4%. Accounts receivable net of reserves totaled $41 million at quarter end, essentially unchanged sequentially with DSOs for trade receivables slightly improving to 37 days. All balances are current. Inventories net of reserves declined 1.5% sequentially to $57.3 million. Annualized turns improved to 3.1. Reflecting the favorable swing in working capital, operating cash flow totaled $19.3 million for the quarter. Capital expenditures for Q4 totaled $11.8 million, representing the value of equipment placed in service during the period. We ended the quarter with a construction and progress balance of another $15 million, and we have approximately $42 million of our capital budget scheduled to be spent through the year. Our factory expansion project is proceeding on schedule and on budget. I'll now address bookings and backlog. Q4 bookings totaled $91.5 million, a 1.2% sequential increase. The overall book-to-bill was approximately 1 to 1 with Advanced Products at 1.4 and Brick Products at 0.9. Q4 bookings largely reflected the same circumstances we saw with Q4 shipments, a strong recovery of North American volume offsetting a return to trend for Chinese bookings and to a lesser extent, the natural lumpiness of orders from Asian contract manufacturers. At year end, 1-year backlog totaled $147.6 million, an increase of 5.4% sequentially. Turning to our outlook for the first quarter of 2021. We expect continued revenue growth. We continue to address the sources of gross margin pressure and are forecasting improvement in product level profitability. Further, we do not anticipate any meaningful increases in operating expenses. While substantial further improvement in gross margin will have to await, production from our new vertically integrated expanded factory, we expect incremental revenue to drive earnings per share given the scalability of our operating model. Phil will now provide an overview of recent market developments, and then Patrizio, Phil and I will take your questions. [Operator Instructions] So, Phil?
