Complicated and depends on many factors. I had actually gotten a letter in summer of 2016 related to overall ARYC case and all other parties over the 4 states. This is a prelude to sending a letter on a specific $ amount reward. They pulled it because there are rules about paying if other collections are expected in the next year or if the total amount is under the $2 million level in an award but might end up going over it when all parts are resolved.
So who knows on that one or what parts have gone through what processes.
On a broad WB scale, it could be 2 years to 10 years, depending.
