Deutsche Asset Management's (DeAM's) Frankfurt operations have won a double-A rating, the third-highest available, from Fitch Asset Manager Ratings (Fitch AMR).

The rating means Fitch AMR considers Deutsche's institutional fund management business to offer investors excellent security. It is a measure of how well the business controls its risks, rather than an indicator of investment performance. But the seal of approval from Paris-based Fitch AMR should open European institutional investors' doors.
