I went to the FAQ section at HY website; the class B shares are not publicly traded so probably wont have a symbol for them. The main difference between class a and class b is number of votes per share; class A gets 1, class b 10. There was a section about converting class a to class b (as I suspect most small investors will want to do so they can eventually sell them) but the answer was to contact the servicing agent which I believe is Compushare. I suspect we'll get something in the mail related to all this.....
