The National Hockey League and the NHL Players' Association issued the following statement today:
"The NHL and the NHLPA have reached a settlement of their dispute over 2010-11 Hockey Related Revenue (HRR). The return of Escrow monies to the Players and Revenue Sharing payments to the Clubs were on hold while these matters were being resolved. The Players' Association and the League have also reached an agreement about how some of the disputed HRR issues will be addressed for this season (2011-12).
"The disbursement of Escrow and Revenue Sharing monies will occur in the coming weeks."
I will guess that the largest chunk of the $20M adjustment in HRR came from including a portion the $25M CoG subsidy in the Final HRR numbers - as was speculated/predicted in that thread.
Note that this discrepancy will not effect this seasons cap - a discrepancy between the accepted Initial HRR Report (which the cap is based on) and Final HRR Report would only be reflected in the cap if it were large enough to change the calculated Midpoint by >$3M. This change (if accounted for earlier) would have only bumped the Midpoint (and thus the Upper Limit) by ~$380K - $20M * 57% / 30 teams.
Pierre forgot that the first year cap was an estimate (albeit a low one) since the NHL was being conservative after their return from the lockout. The cap was based on $200 MM (or more) less than actual HRR prior to the lockout.
