going private transaction is where it better for the company to go private than to stay public, so to achieve this they do a rev split followed by foward split of the same size to get rid of share holders holding less than the split size, the ones removed our offered a tender amount. Like the last the one I did was ASBP where it was 300:1 so hold 300 shares you get the difference between the tender price and the price you bought. For me it was around $1/share profit, pretty much risk free over 4 accts(1200 shares)
