Okay. That's very helpful. I just want to make sure we're all modeling that correctly. And then related -- somewhat related for '22, how should we think about the ongoing earnings hit in the -- from -- you lost a corporate client in the RCI membership. How should we think about that earnings hit? And then also from member loss over the past 1.5 years, I guess, again, as compared to sort of what it was in 2019.
Stephen P. Weisz -- Chief Executive Officer
Yes. Patrick, this is Steve. I think you're referring to the Diamond transition from Interval to RCI, correct?
Charles Patrick Scholes -- Truist Securities -- Analyst
Yes, that -- yes, correct that. And if you and lost members over the past 1.5 years, what is sort of the run rate so we can sort of match it up [Indecipherable] expectations year 2019 again. Thank you.

Let me speak to the diamond things specifically, and then I'm sure John can chime in a little bit on the EBITDA side of things. So Diamond was 165,000 members, roughly 10% of the Interval membership at the time that they lost. We were able to retain 29,000 members from that 165,000 in Interval who continue to want to keep their membership with us. I should also point out that the 165,000, only 15% of those were actually active exchangers. Now 165,000 members, you do get the annual corporate membership fee, which has -- it's not the lion's share of what you get from membership, but it certainly is important money. But the real money made in the exchange business is on a transaction basis when people go to exchange.
So we believe that at the end of the day, by retaining the 29,000 members, which were obviously active users because they wanted to stay with Interval. It's really going to be relatively de minimis in terms of the financial impact from Diamond. Now with that said, there were others that because of you have normal attrition in the exchange business, that happens every year. Typically speaking, what happens is, as new developer sales happen, you have new memberships that are gained and under ideal circumstances, the new members outweigh the normal attrition. Obviously, in 2020, there were very few new member additions being made across the affiliate network, and you still have the continued attrition. So there will be some leakage at the EBITDA side. So I think John may be able to chime in a little bit with some additional numbers.
