stressed valuations

I have compiled a spreadsheet and slashed 2010/11 EBITDA forecasts by between 15-20% from my "normal" figures and then also slashed the EBITDA multiple on all assets other than DBCT, NGPL and Powerco to 7.
I have cut DBCT, NGPL and Powerco multiples by 10%. That's a savage cut for growth assets.
The following are the distressed EV's for each asset:
DBCT 2.7Bn
NGPL 2.4Bn
Powerco 817M
IEG 672M
CSC 140M
WestNet Rail 665M
Alinta 1.316Bn
Euroports 609M

Plug these numbers into the spreadsheet and take away all debt and I come up with a distressed BBI valuation of 4c per security. Now this also assumes no further dilution to BBI through SPARCS, BEPPA or some sort of re-structure.
So, in a WORST case scenario WITH further dilution, BBI could well be close to worthless.
You can see that is imperative DBCT sells for AT LEAST $2.7Bn. I'm hoping for closer to $3Bn as I would for NGPL if it were sold.
