IF UL AND UN ARE SAME COMPANY THEN WHY DO THEY HAVE A DIFFERENT PRICE? IS IT BECAUSE UN IS IN A INDEX AND UL ISN'T OR IS IT BECAUSE THEY ARE PRICED IN EUROS AND UL IS PRICED IN POUNDS AND THEN ARE BOTH CONVERTED INTO DOLLARS AS THEY TRADE IN US. BASICALLY I WANT TO BUY UNILEVER BECAUSE I THINK IT IS GREAT COMPANY, AND I WANT TO MAKE SURE I AM BUYING THE RIGHT STOCK AND WANT TO UNDERSTAND THE DIFFERENCE BETWEEN UL AND UN AND IF THERE IS A DIFFERENCE. AND IF THERE ISN'T A DIFFERENCE THEN WHY DO THEY TRADE AT A LITTLE DIFFERENT PRICES?? PLEASE HELP ME.
