TARP is the latest and greatest, new and improved bailout package being thrown out by the almighty (read: Hank Paulson and Friends inc.). Tarps in the real world cover things up, be it dead leaves, dead bodies, holes. Insert your favorite thing that you would want to hide and that is exactly what this plan does. in this case TARP helps fill in holes on Wall Street balance sheets. The holes is in this case are the mark to market difference between where many poorly performing securities are currently marked and where they could really be sold. Merrill Lynch and E-Trade recently sold large chunks of CDOs at 20 cents on the dollar proving that there are buyers at a certain price.
