Thank you, Patrizio.
As disclosed, Vicor's consolidated revenue for the third quarter decreased to $53 million compared to $55.5 million for the second quarter, representing a sequential decline of 4.5%. The third quarter figure compares to a revenue of $58.6 million for the third quarter of 2011, representing a decline of 9.6%.
International revenue increased 2.9% quarter-to-quarter as an increase in BBU exports of modules, primarily to Asia, was offset by lower V-I Chip shipments also to Asia. International revenue represented just over 52% of total revenue, up from 48.4% for the second quarter.
We experienced another sequential increase in recognized sell-through revenue associated with shipments by our stocking distributors, future electronics and digit key. The absolute figures are relatively small, but the trend continues to be positive. Recognized sell-through revenue totaled $745,000 for the third quarter, compared to $367,000 for the second quarter, a sequential increase of over 100%.
Consolidated gross margin at 43.4 was essentially unchanged sequentially compared to 41.7 for the third quarter of 2011. The year-over-year increase reflects a shift in relative mix made up of a higher percentage of higher-margin bricks as V-I chip shipments declined.
As we've discussed, V-I chip has increased efficiencies and lowered material costs, contribute to potentially higher product gross margins at sustained high volumes. However, at current low volumes, overhead absorption is weak and higher incremental material costs is reflected in V-I chips margins. With the anticipated volumes of Q4 and 2013, we expect V-I chip gross margins to improve somewhat. In addition, our new panel molded packaging process should begin contributing to improved V-I chip [indiscernible] gross margins in late 2013 when volumes of panel molded products are expected to begin to ramp.
Consolidated operating expenses for the third quarter declined sequentially. Largely reflecting lower variable costs associated with lower revenue.
Compensation, by far our largest expense, increased on a year-over-year basis reflecting the added hen count and activity in marketing and sales, but actually, was lower sequentially due to a reduction in stock option activity and associated compensation charges. Total headcount at 1,044 was unchanged quarter-to-quarter. Audit tax and related fees increased largely due to the timing of these efforts.
As earlier reported, net income for the third quarter was $191,000 compared to $220,000 for the second quarter of 2012. Due to rounding, the third quarter figure rounded down to $0.00 while the second quarter figure rounded up to $0.01. The fully diluted share count at quarter end was $41 million, 815,000, up slightly from the prior quarter's $41 million, 812,000.
Total one-year backlog at the end of the third quarter was $42.9 million compared to $42.2 million at the end of the second quarter. Backlog scheduled for shipment in Q4 at the end of Q3 totaled $33.5 million or 78% of the total, in contrast to the comparable second quarter figure of $32.9 million also representing 78% of total backlog.
BBU bookings were flat sequentially with improved orders in modules and activity in Japan offset by a decline in custom systems. Our Vicor custom power business continues to experience uncertain and irregular order flow as a result of Pentagon budget issues.
Europe represents another area of weak references as the economic conditions in the region are now being felt in our order flow, which had been relatively resilient to the bad news coming out of the region.
V-I chip bookings for the third quarter recovered somewhat improving 33% over the very low second quarter figure. Bookings remain under the average quarterly level of 2011 reflecting the absence of orders from the cancelled Blue Waters project and continued delays in orders associated with other super computer projects reliant on uncertain government funding. We did receive some long awaited orders from customers in the enterprise server in defensive electronic fields during the quarter.
Picor had 27% higher bookings for the third quarter. But activity remains slow as Picor's existing merchant offerings have often been sold side by side with V-I chip products. Given the strong reception of the cool power line of point of low regulators with potential customers and the trade press, we are expecting bookings for these products to increase considerably in the new year.
Quarterly pretax income, including interest income and the net effect of accounting for certain changes in the value of our investments totaled $366,000 representing 0.07% of revenue versus the second quarter's $791,000, which represented 1.4% of revenue.
Our consolidated effective tax rate for the third quarter fell below the statutory level to 23.5% for the quarter. It was 48.3% for the year-to-date period ended September 30. The calculation of our tax provision and the derivation of our effective tax rate is made complex by our organizational structure. We calculate each quarter's book provision for income tax expense on a year-to-date basis reflecting our assumptions for the full year pretax income.
As of the second quarter, we were projecting higher full year income, which drove the second quarter tax provision much higher. We have reduced our forecast for the full year based on current performance and have factored this into our new book calculation.
I should note, the calculation does not include any assumed benefit from current year federal research and development tax credits as Congress has yet to renew this credit for 2012 as has been the pattern in prior years. And we cannot be certain Congress will do so before year end. To date, we estimate the loss of this credit has reduced our 2012 net income by approximately $200,000.
The quarterly cash flow from operations fell to $1.4 million from the prior quarter's $5.4 million reflecting a net increase in working capital associated with an increase in accounts receivable.
Capital expenditures remain largely at the maintenance level of prior quarters, but did increase from $1.5 million to $2.1 million. We do not anticipate a meaningful change in our CapEx in the coming quarters. Cash increased by $2.5 million for the quarter.
Turning to the balance sheet, our receivables portfolio remains in excellent shape. Although day sales did increase to 51 days, up from the second quarter's level of 46 days. However, this DSO increase was associated with a customer specific accommodation, not with the deterioration of our overall receivables portfolio.
Consolidated inventories quarter-to-quarter were stable increasing only $32,000 reflecting current booking and shipment activity. Annualized inventory turns stood at $3.9, down slightly from $4.2 for the second quarter.
As of September 30, we had $84.8 million in cash and equivalents. We also hold long-term investment securities carried at a book value of $6.9 million. Included in this long-term total are option rate securities with a par value of $6.1 carried at a book value of $5.1 million representing 82.8% of par.
During the third quarter, we received redemptions at par totaling $3 million but we have reduced our holdings of auction rate securities down to just 2 issues. To date, we have received over 32 million of redemptions at par value. And are confident the remaining balance will in time be also redeemed at par value. In the meantime, we received interest at rates more favorable than we would otherwise obtain in the open market.
I'll conclude with a brief update on our insurance litigation, which has come to a close. After the third quarter ended in early October, Vicor settled its lawsuit against its insurance carriers. And we received $1.975 million in cash in exchange for releasing carriers from further claims. This amount will be recorded as a gain from litigation related settlement in the fourth quarter of the year.
This concludes our prepared remarks and now we'll take questions. Operator, Jody.
