Assets Under Management
The fund has $182 million in total assets, which is below the $672 million average for the Mid-Cap Growth category.

RMB SMID Cap I has an expense ratio of 0.80%, which is 27% lower than its category average, making the fund expense ratio grade a B. While it is difficult to predict returns, it is known that high annual expense ratios reduce your rate of return, and excessive fees are difficult to overcome. Active management normally comes with higher expense ratios than passive index management. Certain investment categories such as small company and foreign also normally have higher expense ratios. It is best to compare fund expense ratios against the category averages for meaningful assessments.
