Kimberly PopovitsThanks Emily. Good afternoon everyone and welcome. We delivered strong financial results in the second quarter highlighted by a 16% year-over-year increase in test volume, and a 13% increase in revenues. These results were driven by worldwide growth in tests delivered across all products and notably from new markets, including DCIS breast cancer, colon cancer and international. Our growth in tests and revenue, along with net income generated in the quarter, exemplify the strength of our business model and delivering personalized genomics to patients around the world. In the second half of the year, we plan to continue investing in our prostate cancer program, the development of clinical applications for next-generation sequencing, and the ongoing expansion of our international commercial business. Additionally as announced today, we have concluded that the best path forward to optimize our investment in the field of clinical genetics is to support the combination of InVitae with a private company, Locus Development, to form a separate independent genetics company under the leadership of Randy, which I will discuss a bit more in detail at the end of the call.
