hi Thomas/All, I went through the thread( https://stat.ethz.ch/pipermail/r-sig-finance/2006q1/000682.html which concerns with swaps).

The proposed settlement in the Microsoft antitrust trial will probably be accepted by the judge unless a lot of people complain soon, even though it lacks any useful enforcement provisions and fails to prohibit many of Microsoft's anticompetitive practices.
