Thank you, Jill, and good afternoon. We continued to deliver solid performance in the second quarter under our returns-focused growth plan, which prioritizes the profitable growth of our business and greater productivity and efficiency of our assets. Our execution on this plan has been consistent and strong since we launched it in 2016 and has produced measurable results. We have realized significant growth in our community count this year, which fueled a 15% year-over-year increase in our second quarter net orders. In addition, by substantially reducing our debt while growing our active inventory, we expect to lower our annual interest incurred in 2019 by more than $40 million since the plan was introduced.
In the second quarter, we accelerated our community count growth by successfully opening 43 new communities, bringing our total openings over the last 12 months to 123, which had us well positioned for the spring selling season. Our second quarter average community count was up 17% from a year ago, reflecting increases in all four regions, with three of our regions producing greater than 20% growth. We expect to continue growing our average community count year-over-year over the next two quarters and remain committed to
