The contract dispute with LDK and Solarworld are discussed in their form 20-F (available on their website dated 4/27/12), on pages F41 thru F43.
In regards to LDK, in arbitration LDK wanted about $63 Mil. plus the $10 Mil. deposit. They got about $30 Mil. plus the deposit. CSIQ made provisions for the $10 Mil., but not the rest (their comment; "The Company believes the allegations are without merit and that the potential for additional loss is remote and, accordingly, has not recorded an additional liability associated with such lawsuit."). So if they decide to pay it and not take this any further, they would take the hit in Q4 or Q1.
In regards to Solarworld, it looks like Solarworld is the one who terminated the contract in December 2011. Little more complicated on the loss contingencies (better just to read their verbiage). There is no mention of any court proceedings, only that; "In the notice, Deutsche Solar AG also reserved its right to claim damage of Euro148.6 million in court". I could not find anything on court proceedings since the release of this 20-F.
