A fair value question

I understand that fair value is = to Cash + (Interest - Dividends).


Why is AEE(stock) trading higher than AEE MAR futures??
AEE pays a dividend on dec 31 2007, so there are NO more dividends to come until expiration which is mar 20 2008.

I can't figure out for the life of me why the stock is trading higher than the futures

 

can someone answer this... this is killing me.


Thank you so much

 

Shareholders as at 5 March get the March divi also (63.5 cents).
