Mark Loughridge - SVP and CFO, Finance and Enterprise Transformation: Thank you for joining us today. In the second quarter we reported revenue of $24.9 billion and operating earnings per share of $3.22. Our EPS includes $1 billion charge for workforce rebalancing. Excluding workforce rebalancing activity in both years, our operating EPS was $3.91, up 8% year-to-year. We had good performance in our high-value, higher-margin businesses, contributing to the sequential improvement in our year-to-year revenue performance into margin expansion.
Software returned to mid-single digit growth. In fact, this was the best constant currency Software growth since the first quarter of 2012. Performance was led by 10% growth at constant currency in our key branded middleware and we gained share in all five brands.
In Services, GBS improved revenue performance and returned to growth at constant currency, while GTS revenue growth was consistent with last quarter. With a significant amount of new business in the quarter, our total services backlog was up 7% at constant currency or 3% at spot rates to $141 billion. Our hardware performance is mixed. We had strong performance in System z mainframe, which generated double-digit revenue growth at constant currency. Power and storage had some modest improvement in year-to-year performance, though still declined. Across our segments, Smarter Planet was up over 25% and cloud over 70% for the first half.
Business Analytics growth improved this quarter to 11% with good performance across GBS and Software. These initiatives addressed key market trends, like mobile, social and big data.
