P = 5E = fair market value
E = net annual earnings (income minus expenses)
income = ppc, ppa, etc.
expenses = amortized buy price, reg fees, taxes, personal time, etc.
Total type-in and back link traffic is unlikely to support E > 0, even if this was a GD 0.99 hand reg. I recommend selling now while swine flu is in the headlines. Good luck!
