Thank you for joining us today for our discussion of Exponent's second quarter 2012 results. The second quarter net revenues increased 13% to $68.3 million, and total revenues were up 14% to $74.5 million. Net income grew by 26% to $10.3 million or $0.72 per share compared with $0.55 per share a year ago.
We are pleased with our second quarter performance having produced double-digit revenue growth and increased profitability. We continue to benefit from the strong demand across the broad range of our services, both proactive and reactive. We experienced high utilization as we continue to benefit from new work in key areas, as well as a few major projects.
In the 50% of our business that is reactive in nature, we continue to see a steady flow of new retentions related to litigation, insurance claims and product recalls from a diverse set of clients. In the 30% of the business that is proactive in nature, we continue to see an increase in new assignments related to design consulting, regulatory consulting and engineering management consulting.
The defense technology development business saw an increase in activity, supporting the U.S. Army's Rapid Equipping Force, which was offset by the winding down of our current U.S. ground penetrating radar development contract.
In our environmental and health segment, we had notable contributions from our environmental sciences, ecological sciences, chemical registration and food safety and exposure assessment practices.
In our engineering and other scientific segment, we had notable performances from our mechanics and materials, electrical, biomedical, vehicle and engineering management consulting practices.
Broad-based demand for our services, the addition to the continuation of a few large projects, led to a strong utilization of 76% in the quarter. Which, along with the moderate growth in expenses and lower share count, resulted in 31% growth in earnings per share.
Only 6% of our revenues are generated from our international offices. We continue to see good demand. In the U.K. and EU, we are seeing increased demand for our chemical and pesticide registration services. In China, business remains strong, driven by our work addressing clients quality-control issue from their suppliers and contract manufacturers.
We are pleased with our performance to date and are optimistic about our ability to weather a difficult economic environment. Since our project work, both in the U.S. and internationally, is in areas that we believe are less sensitive to the economic slowdown. Thus, we are increasing our full year expectations.
I'll now turn the call over to Rich for a detailed discussion of our financial results.
