Thank you, John. Our first quarter results for fiscal year '15 and our second full quarterly reports since the separation reflect the continuing challenges we face in our various markets while also demonstrating some positive results from our actions to improve operational performance. We continue to make meaningful progress on mitigating the impact of government spending levels and shedding impediments to our future growth. We are cautiously optimistic about recent contract activity in some segments of the federal market, federal health in particular. However, our outlook and our experience in defense and intelligence budgets show outlays continuing to decrease through the government's fiscal year '15. We also believe that dramatic differences and priorities between political parties may result in another continuing resolution in the upcoming new government fiscal year, which starts October 1 of this year. Leidos continues to take actions necessary to become more competitive in both federal and commercial markets. I remain convinced that we're doing a good job, improving upon these areas within our control and that we are extracting the value we envisioned in the separation.
We saw our National Security Sector operating income improved, as well as an increase in the sector's funded backlog. And we continued on our journey to shape and optimize our portfolio, completing the sale of CounterBomber, our third divestiture in recent months. We also had success in our efforts to access markets that were either partially or fully conflicted before the separation, seeing strong new awards amounting to more than $400 million in airborne systems, command and control, and logistics. In addition, we have taken initial steps to build our international presence with both government and commercial business where we see demand for our demonstrated solutions. These steps are being taken in a small number of countries, where we have existing footprint, relationships and past performance credentials.
In the area of capital deployment, we substantially completed a $200 million accelerated share repurchase program announced in March. As we have said, our goal is to avoid building excess cash in our balance sheet as we move forward. In the last 6 months, we have returned over $0.5 billion through our share repurchase program, and this represents about 17% of our current market cap. Our cash generation is typically lower in the first quarter, as our results show. That said, cash generation remains a clear priority for Leidos, and we remain committed to utilizing our expected strong cash flows to drive value for our shareholders.
Now turning to our National Security Sector. Revenues decreased by $133 million, or 12% year-over-year, in the first quarter of FY '15. This represents a slight improvement in the rate of decline compared to the fourth quarter of last year. About $78 million of the decline was due to the continued reduction of U.S. overseas war-related, or OCO, business. We continue to expect that OCO-related revenues will be about $400 million in fiscal 2015, down from close to $750 million in fiscal 2014. We believe that we will eventually be able to turn about half of the remaining business into programs of record. It is our expectation that we continue to see a moderation in the rate of decline for our National Security Sector revenues as we move through the remainder of the fiscal 2015, mainly driven by easing comparisons.
Our National Security Sector operating income increased by $6 million to $77 million in the first quarter of FY '15. Our operating income margin was 8.2% for the quarter, up 160 basis points compared to the prior year. The improved margin performance reflects the ongoing impact of our cost reduction initiatives and solid program execution. I am pleased to note that these initiatives more than offset the overall impact of revenue decline.
National Security Sector net bookings for the quarter were $474 million, resulting in a book-to-bill ratio of just over 0.5. Our funded backlog increased by 6% year-over-year and grew 7% on a sequential basis. One notable recent win was the Combatant Craft Medium contract, a specialized vessel for the U.S. Special Operations Command. We have been pursuing this program for several years, winning an aggressive competition to develop and field initial units using our vessel design and unique capabilities and leveraging the commercial shipbuilding supplier base. This win further solidifies our competitiveness in the DoD solutions space.
Now on to Health and Engineering. Health and Engineering revenues decreased by $141 million, or 27% year-over-year. The revenue contraction reflects 4 main factors: first, the completion of 2 alternative energy power plant construction projects, Plainfield and Gradient, which boosted revenues by $63 million in the prior-year period; second, the timing of security product shipments. In the first quarter of fiscal 2015, we had a relatively low level of shipments due to the completion of a large international systems maintenance contract last year and due to our schedule for delivery of new security product shipments, which are concentrated in the remaining quarters of this year. Third, while we saw a sequential improvement in our commercial health revenues for the first quarter, we experienced a decline on a year-over-year basis. And finally, we had fewer new starts in our design-build engineering business. Overall, we believe our Health and Engineering revenues will build modestly as we move through the rest of the year, driven largely by higher levels of security product deliveries.
Health and Engineering operating income decreased $10 million in the first quarter, a result of the lower revenue volume, the low volume of security product deliveries and operating losses associated with the Plainfield biomass power plant. Excluding any unforeseen items, we would anticipate our sector operating income to increase as we move through the rest of the year, driven primarily by the expected increased volume in security product shipments in the remaining quarters and an improvement in the results from Plainfield operations.
Our Health and Engineering business had a book-to-bill ratio of 1.0. Total backlog for this sector was $1.85 billion, up 5% compared to the prior year, while the funding backlog was $1.12 billion, up slightly year-over-year.
Looking at our total company business development results, consolidated net bookings totaled $857 million for the first quarter and produced a book-to-bill ratio of 0.65. We ended the quarter with $8.8 billion in total backlog, $3.1 billion of which was funded. Total company backlog was down 6% year-over-year, while funded backlog was up 5% over that period. The value of bids outstanding at the first -- at the end of the first quarter was $11.9 billion.
Finally, before I turn the call over to Mark, I'd like to give you a quick update on the board's ongoing CEO search. We have identified a number of excellent candidates, both internal and external. The board is devoting considerable attention to the interview process, and I am optimistic that we'll be in a position to conclude the process in the near future.
With that, I'll now turn it over to Mark, who will discuss the financials and the outlook for the rest of the year.
