Valuation risk of a security—uncertainty about its fair value—is a subject of considerable concern in the mutual fund industry. If funds report different values for identical securities, investors cannot easily compare performance. Yet it is not unusual to see identical illiquid stocks,...

This study analyzes the loss potential arising from investments into CDS for a sample of large U.S. and German mutual funds.
