Fannie Mae (FNMA)

[Red Captain]

Apologies but I think you have made a few errors:

First a terminological one: I didn't calculate anything, I laid out a relationship between variables.

Moreover there is nothing wrong with the equation in the abstract.

Finally, I did put a suggestion at the end of my original post for taking account restored preferred dividends:

"Perhaps another variable that could be added (deducted from net earnings in the bracket is dividends to preffered shares)

I am not sure your equation does that correctly, since it seems deduct the dividends from after they are multiplied by price to earnings ratio. Maybe just a error made in haste.

Still, it remains that you still have an indeterminacy; You are stuck a function, not answer for pps.
