Thank you, John. So our goal is two-fold. One is to advance our portfolio and market share in specialty products, dental, endo, ortho, implants, bone regeneration and products that are supporting those professionals and providing specialty dental care. At the same time we've started advancing our specialty area focused in the medical arena with a line of orthopedics, blades and swords that we're doing quite well. We've and had been focused on that also for a while and we focus on expanding that portfolio. So that's one area which is also supplemented, by the way, with the Henry Schein One offering because you could view it as a private brand or a corporate brand, if you will, because it's our own brand, but that's all services, the practitioner with unique products under the Henry Schein brand. At the same time, we have led for years with the expansion of sales led by an expansion of product offerings of high-quality, price-competitive products that we offer through our private brand and corporate brand. And we will continue to do that. Having said that, Henry Schein is primarily a branded, national brand for valued-add [ph] products. However, where we experience price competition, we lead very often with our corporate brand, our private brand, which is highly competitive and enables us, of course, to compete very nicely. So it's with branded products, our own branded products that are in the specialty areas and software, and private brand where we are offering competitive pricing, however, fully mindful of the fact that we are a national brand supporter and wish to continue to grow our relationships with those manufacturers of national brand products that see Henry Schein as a great partner.
