AdBrite monthly payment | Do they include month before?

I was reading there terms and conditions, and one bit confused me..
So i’m basically asking those who use adbrite.
Let’s say you set your minimum check amount to $100.
If after the first month, you do not reach $100 within a particular month, do they include what you did make that month (let’s say i made $40), onto the next month?
It would seem pretty ruthless not to pay for what you made the month before, so I just want to verify this..?
Thnx
