Question #4: Is my “beneficial interest” the amount of money that will be distributed to me from the Liquidating Trust?

No, it is not a guaranteed amount.  Your “beneficial interest” is the percentage your claim represented of the estimated current value of the assets transferred into the respective Liquidating Trust. It is your share of the assets in that trust on the first day that trust existed.  Since that time, the trust has liquidated its assets, paid expenses, and distributed your percentage of the available net proceeds.  Please consult your tax advisor regarding the impact of your “beneficial interest” on your specific tax situation.
