Amusingly, the voting shares are currently worth less than the nonvoting.
They should issue a class of shares that are guaranteed to never pay a dividend or be redeemable for anything. Maybe they will trade even higher!
I just checked and you are right (1835 vs 1827). Funnily, there is this:
"but unlike common shares, they do not confer voting rights to shareholders. As a result, these shares tend to trade at a discount to Class-A shares. "
