question for wrench. lets say for example I own 10

question for wrench. lets say for example I own 10 mil shares on march 14 as a registered shareholder. to receive the series c's. will my 10 mil commons be tradable  come the 17th or 18th or will they be held as collateral for the series c's. and be released in 6 mo. when the c's are redeemable. either way im long. that's the only thing I'm fuzzy on. thanks
