Assuming 520 remaining claims, projected claim resolution finish date is March 2016.
Assuming:
4521 original claims
@11.6 claims/wk
4001 claims/6.625 yrs = 603.9 claims/yr or 11.6 claims/wk
520 claims/11.6 = 44.8 wks or 10.3 months
Note: Nothing, I believe, says all claims must be settled prior to distribution commencement, although, most assuredly, someone is collecting the interest.
