Shareholders do their own DD. The last Asher CDs (those litigated and canceled) were 2012, so claim in 10+ years ago? They were hard lenders with 660 OTC clients, no court cases.
The first public info about Asher toxic lending as stated in Court Papers submitted in evidence by DBMM was the Mazuma case in Nov 2013. The same month as the SEC re-audit mandate.
