Thank you Patrizio. I'll now review our quarterly performance providing some background and business unit specifics. Consolidated bookings for the fourth quarter totaled $50.1 million, a decline of approximately 12% from the prior quarter. Total 1 year backlog, at year end, stood at $54.2 million, a decline of approximately 14% from the prior quarter. Backlog scheduled for shipment in Q1 at the end of Q4 totaled $40.4 million, or 74% of total backlog, down from $45.7 million of backlog scheduled for shipment in Q4, at the end of Q3, which represented 73% of total backlog.
BBU bookings were stable, quarter-to-quarter, with a decline in Japanese bookings offset by an increase in Vicor Andover bookings. As commented on last quarter, we believe the decline in Pentagon spending, on the types of communications solutions we power, an important driver of North American BBU demand, has ebbed. We do not anticipate a return to the levels of 2009 and 2010 in the foreseeable future, but we expect the current level of activity to be sustained given, again, the nature of the programs we support.
As should be the case with many of the BBU products targeting industrial and transportation applications, we expect future growth in defense electronics will be the result of the use of our advanced V-I Chip and Picor technologies in meeting the high performance requirements of next generation applications.
As Patrizio mentioned, V-I Chip bookings were off sharply, as cancellation of the Blue Waters supercomputing project, took a big bite out of our bookings forecast for 2012. However, our perspective on VI Chip’s 2012 bookings and revenue is brightened by recent developments in the Intel-based server space that Patrizio spoke about a moment ago.
Picor's bookings increased 19% sequentially, reflecting the uptake of new products announced during the year, notably quiet power filters. With several new product announcements recently and the planned roll out of SiP-based regulators, we anticipate continued momentum for Picor.
Turning to revenue, Vicor, as stated, recorded consolidated revenue of $58.6 million for the fourth quarter, the same level we recorded for the third quarter. We did experience a slight shift in mix for the quarter. BBU revenue increased 5.1% sequentially, based on improved shipments from the Vicor Andover modules business, our largest, and our Vicor Custom Power entities.
V-I Chip revenue declined 12.4%, reflecting the rescheduling of certain shipments from the fourth quarter to the current quarter. Picor revenue declined almost 39% quarter-to-quarter, due to an inventory correction undertaken by a contract manufacturer for Picor's largest customer. We do not anticipate a recovery of this volume in the near term, but do expect increasing shipments of new products throughout the year. As previously discussed, we have adopted a multi-channel distribution strategy and announced our relationship with Digi-Key, this quarter.
With the new Digi-Key relationship, and a maturing Future Electronics relationship, we expect our financial statements will reflect increasingly higher sales through these stocking distributors. However, for the fourth quarter, our newly established relationship with Future Electronics generated only modest sell through.
Our mix of North American and export revenue was consistent, quarter to quarter, with international revenue representing 53.7% of Consolidated total revenue, down slightly from the 55.8% share in the third quarter.
Fourth quarter shipments to Asia Pacific, which excludes Japan in our definition, recovered and would have been much higher but for the decline in shipments by V-I Chip and Picor to Asian contract manufacturers working on behalf of our large customer.
The Asian industrial markets, and in particular, the Chinese railway market, appear to have caught their breath in the second and third quarter of 2011 and have now recovered. We are hopeful their current relative strength will be sustained.
Consolidated gross profit margin as a percentage of revenue for the fourth quarter was 41.8%, essentially unchanged from the prior quarter. The change in product mix was reflected in a slightly higher margin for the BBU, and a slightly lower margin for the VI Chip, reflecting volume-related changes in overhead absorption.
Consolidated operating margin as a percentage of revenue for the fourth quarter was 2.1%, down sequentially from the third quarter figure of 2.9%.
The expansion of our marketing and sales effort, again, was a driver of higher spending, as our SG&A expenses increased 5% sequentially.
Higher legal fees associated with our SynCor litigation also contributed to the fourth quarter increase.
R&D expenses, predominantly compensation, declined 2% sequentially, but this was largely because of the relatively high stock option expense included in the Q3 total.
Quarterly pre-tax income, including interest income and the net effect of accounting for certain changes in the value of our investment portfolio, totaled $1.2 million, representing 2.1% of revenue, in contrast to the third quarter pre-tax income of $1.7 million, representing 2.9% of revenue.
Our effective tax rate for the fourth quarter was 36.9%, but for the full year was 33.7%, reflecting the methodology by which we calculate a full year provision and adjust our calculation of the incremental quarterly tax due based on a comparison of our original pre-tax forecast to actual results.
Cash flow from operations totaled $4.7 million for the fourth quarter, up slightly from $4.6 million for the third, reflecting a net reduction in working capital for the period.
Our net capital expenditures remained at the maintenance level of $1.2 million for the fourth quarter, the same level as the prior quarter.
While we anticipate the need to add production capacity, we are focused on enabling capacity expansion that minimizes incremental CapEx.
Turning to the consolidated balance sheet, our receivables portfolio remains in excellent shape with day-sales at 46 days up slightly quarter-to-quarter from 44 days. Consolidated inventory's quarter-to-quarter declined very slightly and our annualized inventory turnings stood at 4.1, a slight decline from 4.2 for the Third quarter.
At December 31, we had $71.9 million of cash and equivalents, as well as long-term investment securities carried at a book value of $9.6 million. Included in this total are auction rate securities with a par value of $9.1 million that are carried at a book value of $7.5 million.
I'll now turn the call back over to Patrizio for a few closing remarks before we take your questions. Patrizio?
