Thank you, Irene. Good afternoon, and welcome to Vicor Corporation's conference call for the first quarter ended March 31, 2015. As stated, I'm Jamie Simms, Chief Financial Officer; and with me here in Andover are Patrizio Vinciarelli, Chief Executive Officer; and Dick Nagel, Chief Accounting Officer. Today, we issued a press release summarizing our financial results for the first quarter. The press release is available on the Investor Relations page of our website, www.vicorpower.com.

In addition, a replay of the conference call will be shortly available on the Investor Relations page of our website. As is our practice, I'll start this afternoon's discussion with a review of our financial performance for the quarter, and Patrizio will follow with his comments, after which we will take your questions.
As set forth in this afternoon's press release, Vicor recorded a net profit for the first quarter of $3.4 million, representing $0.09 a share on revenue of just over $64 million. For the fourth quarter, we broke even representing a loss per share of nil, i.e. $0.00, on revenue of $60.7 million. Notably, operating income increased by $3.8 million on a sequential quarterly revenue increase of $3.3 million. General and administrative expenses declined. Marketing and sales expenses also declined since trade show, promotional and advertising activities declined during the fourth quarter. Research and development increased only slightly with an uptick in function of prototype material.
Unlike prior quarters, we did not record any unusual or otherwise nonrecurring transactions, which further highlighted the leverage in our operating model. With the exception of legal fees, our cost structure is relatively predictable. While we continue to refine our organization and are always looking for ways to reduce operational costs, we are not forecasting material changes to our cost structure for the remainder of this year. We continue to pay severance and related shutdown costs associated with the fourth quarter closure of our Westcor operation in Sunnyvale, California. But those accruals occurred last year and the payments going forward have no income statement impact.
Turning to the performance of our business units. The Brick Business Unit as a whole recorded a 4% sequential decline in revenue as both our customs business -- custom business and our Japanese subsidiary experienced weak overall sequential comparisons BBU are difficult as we transition the way we record manufacturing and sale of Westcor's AC to DC systems in the first quarter. Westcor had been segregated until December 2014. Such activities are now included in our Andover operations, and we are not providing Pro Forma comparisons. I will say that shipments for the first quarter of AC-DC systems decline, given the surge in last-time buy and buffer stock orders that were shipped in the fourth quarter.
BBU bookings declined 4.6% for the first quarter. We saw softness across North America, Western Europe and the Pacific rim but are not yet seeing any trends or meaningful shifts in our competitive position. As discussed during prior earnings calls, we are anticipating our new highly-differentiated Vicor integrated adapter, or VIA products, to make a strong contribution to BBU's growth opportunities in computing, networking, wireless telecom, industrial and defense markets. However, substantial volumes of VIA products will not start to ship until 2016. BBU bookings were strong in China after a 2-quarter low. We also saw encouraging strength in smaller but high growth market such as Israel. This encouraging strength was close enough to offset the declines elsewhere, leading to a book-to-bill ratio for the BBU, our largest business unit, of just over 1:1.
VI Chip revenue for the first quarter increased 36% to some extent because of shipments that had been scheduled for Q2 delivery and rescheduled to Q1. Listeners will recall I spoke to this possibility during our last conference call on February 23. We suspected that customers pulling backlog from Q2 into Q1 would contribute to higher Q1 revenue but at the potential cost of lower Q2 revenue. So I will, thus, discuss in a moment, this has proven to be the case. VI Chip bookings, like revenue, has been characterized by application concentration in the data center space, and this was again the case for the first quarter. For Q1, VI Chip bookings declined 16%. We believe in anticipation of the introduction of the next generation of Intel processors, VR13, which is expected to ramp in 2016, manufacturer servers that would've otherwise been deployed in 2015 may be delayed to realize the benefits of VR13 as compared to the current generation, VR12.5. To the extent our footprint with Factorized Power solutions across applications and customers will increase going from VR12.5 to VR13, this product transition is a mixed bag in that it may cause near-term softening in demand but should result in substantially greater total revenue as VR13 applications begin to ramp.
On a related front, which Patrizio will address, his charge is significant design wins for our new Chip modules both as front load forward-mounted devices and in chassis mount VIA packages, which validates our expectations of market reception for these products. As design cycles are typically at least 9 months in our targeted markets, we are forecasting production volumes and a beneficial diversification of customers starting as soon as Q1 2016.
Vicor revenue increased 35% for the first quarter, reflecting a dynamic similar to VI Chips. Vicor's recent revenue and bookings have been driven by the by the VR12.5 data center applications. While one might expect our VI Chip VTM 3 and our Picor CRM 3 SIP solution could be ordered on a 1:1 basis, not necessarily the case. Vicor [indiscernible] orders sometimes lagging VI Chip orders for certain applications by as much as a few months. So while VI Chip bookings decline, Vicor bookings increased 39% for the first quarter.
Recognized distribution revenue for Q1 declined 12.5%, reflecting a slow March. Our efforts to increase design wins through distribution channels continue, but this is being accomplished with reduced reliance on distributor stock, which is not a good fit for our mass customization model. Concluding on consolidated revenue, international revenue based on the location of the party to which we ship, rose 64.7% -- excuse me, rose to 64.7% for the quarter, reflecting the use of Asian contract manufacturers by some of our OEM customers. Vicor's consolidated gross margin percentage for Q1 rose to 45.1% in the prior quarter's 33%, reflecting the strong performance of VI Chip and Picor. The BBU's gross margin was steady, declining slightly from 45.2% to 44.6% due to mix but weighted particularly by BJCL's performance. VI Chip's gross margins achieved a record level reflecting 2 important factors: first, increased production runs; and second, cost advantages of the Chip manufacturing platform. We're very pleased with the progress made by the VI Chip manufacturing team and expect additional margin improvements as we plan for greater capacity utilization in 2016. As we have highlighted before, Picor has a fabulous production model with relatively high gross margins, excuse me. For the first quarter, Picor's gross margin increased to record levels.
Notably, in Q1, VI Chip and Picor gross margins in aggregate and after intercompany eliminations, were accretive to our consolidated gross margin. Said another way, combined VI Chip and Picor gross margins, third-party sales exceeded the third-party gross margin of the BBU. This meaningful achievement implies 2 things: first, we have advanced far along the learning curve with manufacturing our innovative products; second, these cutting-edge new products developed by Picor and VI Chip are targeted at applications for which their value proposition is compelling and commoditization pressures are avoided.
Turning to taxes. Our recent calculations of quarterly income taxes have been more straightforward. For Q1, this was the case with our effective tax rate, despite initial profitability, coming in at just 3.9%.
Turning to cash flow for the quarter. Operations generated $5.1 million, even with net working capital experiencing unfavorable $1.3 million swing, representing the use of cash. With the increase in revenue, accounts receivable rose as did accounts payable, although inventories actually declined. Capital expenditures for the quarter declined to $1.5 million from $2.3 million for the prior quarter, partially reflecting the completion or near-completion of the buildout of the Andover manufacturing space to accommodate Westcor production, a substantial repositioning of certain production lines and the buildout of new capacity for ChiP and VIA production. We are not forecasting a meaningful change in the average level of recent capital expenditures for the coming several quarters. Manufacturing is now fully consolidated, and our operational teams have proven to be quite skilled at capacity management, most notably in support of new products.
Turning to our consolidated balance sheet. Our receivables portfolio remains in excellent shape, with days sales at 42 days, despite the 14% sequential dollar increase. Consolidated inventories quarter-to-quarter declined. Annualized turnover climbing to 5.2x, representing yet another new high. There were no meaningful changes in either AR or inventory reserves. Cash and short-term investments stood at $59.3 million at quarter end, up from $55.5 million at the end of Q4. This figure excludes 1 last auction rate security with a par value of $3 million carried on our balance sheet at an estimated fair value of $2.6 million, representing roughly 85% of par. Employee headcount as of March 31 was 1,033, up 19 from 1,014 at year end. Approximately half of this increase was associated to temporary hires in manufacturing. We also added 2 positions in Andover to replace a subset of the positions eliminated in Sunnyvale with the closure of Westcor and the transfer of production here.
Turning to our expectations for the second quarter of 2015. We are forecasting a sequential decline in revenue. While we do not expect a material change in our operating expense, the expected decline in revenue likely will cost profitability to significantly decline. However, as evidenced by the progress in gross margins for Q1 brought about by a higher mix of ChiP and SiPs, we expect the higher levels of capacity utilization to be achieved in 2016 to generate higher profitability with ChiPs, SiPs and VIA products. Also as discussed in our February earnings call, our operating expense structure is established and capable of supporting much higher sales, so the primary variable impacting quarterly performance going forward will be the amount of revenue we generate in excess of breakeven level in the range of $59 million per quarter.
Now I'll turn the call over to Patrizio, who will address our challenges and opportunities in greater detail.
