When I think about 2022, the MA adjusted operating margin guidance that we announced today of 29%. That includes 150 basis points to 200 basis points of margin compression from recent acquisitions and movements in foreign exchange rates. And in addition to our multiyear initiatives in high growth markets, We are targeting investments to bolster our best in class sales force and to focus on cross selling opportunities across multiple product lines. For 2021, as I think about sort of run rate here, and I think here's the key point that you're driving at, our full year guidance Anticipates in the Q1 of 2022 expenses to be about $120,000,000 to $140,000,000 lower than the 4th quarter, and that's primarily due to the reset of our incentive compensation accruals as well as lower levels of organic investments Given we accelerated some of that investment spending into that 4th quarter, and if I think about now just within 2022, Annual Mirror increases, I would say, as well as talent acquisition and ongoing organic investments, they'll contribute to an expense ramp during the year of somewhere between $80,000,000 to $100,000,000 So view Q1 2022, the $120,000,000 to $140,000,000 lower than Q4, which of course will support margin And then think about during the year is $80,000,000 to $100,000,000 $80,000,000 to $100,000,000 of expense ramp.
