Structured Securities Report Card
每个月, 存 measures sigma levels for a variety of transaction processes, including those for underwriting, 赎回, dividend and interest payments, and reorganization announcements.
The sigma levels evaluate the accuracy, 质量, and timeliness of these processes, and different sigma levels measure these factors in different ways – an "internal" sigma level measures the impact on the process of defects identified as originating within 存, an "external" sigma level measures the impact on the process of defects identified as originating outside 存 (e.g., as the result of bad input by an agent or a service provider), and an "overall" sigma level measures the performance of the process generally, without distinguishing between the sources of the defects.
