Meaning of the word "carter" in business

This is from the transcript of a conference call that reported a company’s quarterly results:

“In this model, we would contribute and install the system at a cost of about $700,000. The [customer] will contribute the retrofit cost of about $250,000. We will then negotiate for recoupment carter, let’s say 75/25 in our favor until we both recoup, and then split the profits 50/50 going forward.”

Is the word “carter” commonly used this way in business? I’ve never heard it before, and I haven’t found a dictionary or other resource that offers a definition that would be appropriate in this context.

If it is a correct usage, can you offer a complete definition. If not, can you suggest what word might have been meant in its place?

I’ve listened to the recording, and it seems to be what the speaker actually said, so I don’t think it’s a transcription error.

Thanks.

This may be a complete WAG, but could it be “recoupment par terre”?

par terre
A re-starting position in which a wrestler is on the mat, on hands and knees, and the other wrestler kneels beside him, with both hands on his back. (French for “on the ground.”)

It’s not that large a step from that to “one partner starts in a lower position than the other”, really.

And understand that I have NO idea if the term is even used that way in the context you’re talking about. It’s about the only thing I found in a 1/2 hour of searching for soundalike terms, though.

jayjay: thanks for spending so much time on that.

After listening to the recording a couple of times to see if it could possibly be “par terre,” I think I’ve come up with the answer: “corridor.”

And a quick Google finds several uses of the phrase “recoupment corridor.”

Mods, you can lock this thread if you want.

Thanks all.
