for the "nightly business report," i'm steve leishman in walk. >>> the auto maker is not firing on allylinders, green light capital david einhorn is now calling on gm to split its stocks into two classes. he wants one class to receive gm's current dividends and another to be more growth oriented. in a phone interview earlier today, mr. einhorn explained his plan. >> i would compare it to an ice cream stand, that just serves chocolate and vanilla swirl ice cream. if you gave investors more choice, some people like chocolate. some like vanilla, some like swirl. if you have to implement in our policy, you would wind up with one share each. so if you like the swirl that you have today, you could keep the swirl. if you would like to have more dividends, you could sell the capital appreciation sales. if you like just the capital appreciation the lone multiple, then you could sell the dividend shares and buy the capital depreciation shares. >> general motors is not buying the chocolate, vanilla or the swirl. they say it creates unacceptable risk. it is not in the shares, of gm up 2.5% today.
