details on why i'm negative on ppx, page-21

Addendum to above for Maple-Brown Abbott

Using the same methodology as above:

MBA became a substantial shareholder with 23M on June 28, 2005 and still holds 12.36%;

Its last transaction was on August 28, 2009;

Net investment is estimated at $188,815,126; and

Average price paid is estimated at $2.52. Ouch.

So MBA is stuck like the majority of PPX holders.
