This feature is useful in several ways:

1. A client You can compute Non-Brinson attribution effects using Perf Calc Calculation and then commit those them in Eagle’s performance Performance tables. The sum of single period effects usually reconcile to the excess returns. However, the multi-period sum of effects is not equal to the linked excess returns creating residuals. Once the effects are smoothed with the Carino 99 algorithm, the residuals would disappear.
2. This feature can be used by a client with an in-house attribution system to break-down excess returns but would like to use Eagle’s smoothing algorithms to ensure that the computed effects reconcile to the excess returns.
3. If a client has pre-computed unsmoothed attribution effects from a legacy system, it can be loaded directly into performance tables and smoothed with Eagle’s smoothing algorithms.
