Yes. So, Salveen, just on capacity, just to give you a frame of reference, we ended the quarter with about $1,700,000,000 of cash on hand. And when you think about our capital structure, about $6,300,000,000 in total debt on an EBITDA run rate of about $3,300,000,000 to $3,400,000,000 So it's below 2 times gross, that's a very modest amount. And when you think about capacity, we're pleased with about $2,000,000,000 of free cash flow year to date, dollars 901,000,000 in the quarter. So with a couple of $1,000,000,000 plus of free cash flow per year and less than 2 turns of gross leverage, you can see over the next couple of years, if you added a reasonable amount of incremental debt at some point in time plus the free cash flow and the cash on hand, there's comfortably $8,000,000,000 to $10,000,000,000 of capacity that you've got over the next year or 2 in order to collaborate and transact and look at acquisitions and other things that we can do to help supplement our growth.
