David, do you want to take the second one, and I will — I’ll say just briefly how this all came about. I mean, David — we have obviously looked at WestRock for a long period of time together, and we’ve had conversations on and off for a number of years about different ideas. David and I met in early January and discussed different ideas. And in the end, we decided that this was the best idea for long-term, short-term and even medium-term shareholder value creation.
And so collectively after nearly 8 months of discussions, we came to this conclusion that we’ve announced today. So it’s been a long time being discussed between companies, but different options. And as I say, at this at the end of the day was what I think — and I don’t want to speak for David, but I think I will here, but you can speak to yourself, David, that this is the best opportunity for both sets of shareholders.
David B. Sewell
CEO, President & Director
Yes. Tony, just to add on to the second part of the question. As part of our transformation and also going back to the previous question, our $1 billion cost and productivity initiative is separate than the $400 of synergies. And we do believe there is upside to the synergies. If you look at the Gondi acquisition that we did, we had a $60 million synergy target. We’re already tracking 30% greater than that.
So we see tremendous opportunities with our ability to bring the companies together. And when I think about accelerating our transformation and why this is such a good transaction for our shareholders, our customers and our employees is in addition to our margin focus, our leverage, our ability to deleverage the company, which is a huge focus, will be accelerated.
Our ability to recapitalize our assets, which is a journey we’re doing will allow us to be accelerated, our vertical integration as a percent of overall sales allows us to be significantly accelerated. Our return on invested capital allows us to be accelerated. These are just core fundamentals that we’ve been really focused on and by joining forces with Smurfit Kappa, all of this gets accelerated. So there’s short-term value. And then you look at the long-term value with the solutions that the 2 companies bring that’s what gets us so excited about the future.

Sorry, okay. Just the integration that, can you share with us the sort of amount of tons that would Smurfit currently is short, i.e., that WestRock will supply into the Smurfit system in the Americas.
Anthony Paul J. Smurfit
Group CEO & Executive Director
Well, if you have normal growth, we would be in around the 400,000 tons, if you had normal growth, but at the moment, somewhere between 325,000 and 350,000 tons, but not all of that will necessarily go into the WestRock system because there’ll be some specific grades. So you can count on somewhere between 250,000 and 300,000 tons that without growth, will come into the system. But obviously, we have been growing in Latin America historically quite strongly, and as have WestRock with their acquisitions in Mexico. So there’s a large kraftliner growth integration opportunity as we go forward.
