Yes, terrific question. [indiscernible] to expand on that. If I think about the equation that we were managing in 2023, we've been seeing around a 2%, 2.5% underlying expense growth. And that's with the benefit of significant efficiencies that we're generating this year. I estimate that’s around 1% benefit in expenses in 2023 for these cumulative initiatives we are running for the last six, 18 months and self-funding underlying investments. We've talked about this model before, driving efficiencies is the core, keeping the underlying core at a low level with the funnel and outsized level of investment and expense growth into key investment earnings like tech, marketing, new additions of personnel to support new strategies, those underlying investments are up almost 20% in 2023, which is what we will hold the competitive capabilities that we’ve got. As we go into -- that model is what drove the overall roughly 2.5% growth that we saw in 2023. I think what we're seeing as we go into 2024 is roughly similar sort of underlying expense management program, really modeling down somewhat the underlying adjustments in light of the environment, clearly, but also bearing some modest incremental impacts of just the cumulative inflationary environment and the efficiencies will rise as well. And so, the net kind of underlying run rate that I would have expected into next year is around 2.5%. And then on top of that, we are accelerating, again, these investments in regulatory response, risk management capabilities that represents the additional 1.5% expense growth as we go into next year. That's the 4% trajectory. If I think about where we're investing just to touch on this briefly, continued focus on core strategy investments, delivering the TCF revenue synergies, growing our commercial bank through vertical specialized – specialties, expertise, digital and product development in our Consumer Banking and Business Banking division, continue to drive the fee revenue strategies and capital markets, payments and wealth. And then on top of that, clearly dealing with these additional areas around Basel III, CCAR, liquidity, interest rate risk management, resolution planning and data and alteration.
