NOTE to WSC Contributors: We realized after the last mailing that some WSC case contributors received the wrong slide for case 17-1 (labeled UFSM-2). The correct slide is labeled UFSM-1. Since we do not know which institutions received the wrong slide, please return the incorrect slide, and we will send the correct one.
