The Libor lawsuits keep piling up.

Last week, New York-based Berkshire Bank filed a class-action suit against the 16 banks responsible for setting Libor -- the widely used interest rate that is now known to have been manipulated by bankers for years.

Berkshire alleges that transactions worth "tens, if not hundreds, of billions of dollars" were affected by the tainted Libor data, and that it may have resulted in less money coming in for lenders like it, according to The Wall Street Journal.
