Bryan Riggsbee - Chief Financial Officer
Management
Yeah. Sure. Thanks for the question. Just in terms of our prioritization, we obviously would prioritize, and as stated that we would prioritize, M&A above share repurchase. And we have an active program for looking for opportunities. The landscape in molecular diagnostics is rather sparse, especially for the types of targets that would meet our filter. So, while we remain active in the absence of things that would meet our criteria, we look to our share repurchase program and that's why you've seen us continue to buy back our shares, 600,000 shares in the quarter, $42 a share. So, we're still committed to the buyback program.
Joel Harrison Kaufman - Goldman Sachs & Co.: Great. And then just one on the UNH policy document, can you maybe just dive in a little bit deeper and clarify how you're interpreting the guidelines? I mean, I think there's a comment in there about specialized ongoing training. Just to understand why the majority of the claims wouldn't be denied if the docs haven't actually had that specialized ongoing training.
Mark C. Capone - President & Chief Executive Officer: Yeah. Thanks, Joel. So, the way the UnitedHealthcare policy is written is it's entirely consistent with decades-old policies from ASCO, ACOG and a number of other breast cancer, SPS and others. What the policy requires is for the physician to do a self-attestation that, in fact, they have had sufficient training to be competent in doing hereditary cancer testing. So, it's up to the physician to make that determination and to declare that determination to UnitedHealthcare. Now recognize, we've, through the years, had over 90,000 physician order tests from Myriad. Tens of thousands do so on a routine basis. And so what we've seen is that all of those physicians have, in fact, attested to the fact that they are capable of providing genetic counseling. It's important to note that the reason ASCO and ACOG have both taken public positions about the capabilities of their members is that they have received training and counseling. As you might imagine, an oncologist is often faced with communicating very challenging and difficult information to patients as is an OB/GYN. And so throughout their medical profession, they've received a lot of training on how to provide counseling. Many have taken short courses that have been offered by these medical professional societies, et cetera. And so that's why these societies have all said they believe all of their members are capable of providing this service and we have seen all of these members attest to the fact that they are. So, it's really just a self attestation on the part of the physician as to whether they can do this and like I said, to date, we've seen all of our physicians that have stated their competency in providing this.
Joel Harrison Kaufman - Goldman Sachs & Co.: Thanks.
