Most of the Lehman I-hub people are on the LEHJQ board.
As for your investments the choices are up to you. I personally do not hold any commons (LEHMQ).
I hold mostly Trust Preferred shares (LEHKQ, LEHLQ, LHHMQ, LEHNQ all $25 face value) as they are subordinate debt and not equity like all the other preferreds are. Those and only those 4 shares are debt and because they are they are the safest shares to own.
Below these are the regular preferreds (LEHCQ, LEHDQ with a $50 face value), (LEHFQ, LEHGQ, LEHJQ with a $25 face value) and (LBHGP and LEHPQ with a $1000 face value).
The best way to learn the differences is to go look in all of these I-boxes and decide which one works best for you.
Do your own homework before you buy anything so you know what you have. Now you know where to look! GLTY
