a little perspective and then I'll Turn it over to Chuck for his commentary. It's a really good question. I think to give you some perspective and we just chatted about this a little bit earlier today In terms of just looking at the math, when you look at the cash flow over the last 2 years, Frank, if you use the midpoint Our guide for this year, the $1,450,000,000 that adds to $3,600,000,000 So in other words, the 2,150 From 2021 combined with the midpoint of our current guidance, if you use the midpoint again of our guide, you referenced that $800,000,000 of share buyback That would sum to a total of $2,550,000,000 over the 2 years, dollars 2.55 $1,000,000,000 when combined with $800,000,000 of dividends. So $1,750,000,000 in share buyback, dollars 800,000,000 in dividend gives $2,550,000,000 which is about 70 percent of the $3,600,000,000 So it obviously reinforces what we've stated In terms of our commitment to return cash to shareholders, I'll let then Chuck really give a strategic lens against that backdrop.
