| 1. | Each Index is a “price return index,” not a “total return index,” and therefore does not reflect dividends paid on the securities comprising the Index. This will cause the Index to underperform in comparison to a direct investment in a total return Index. |
| 2. | If your Strategy Account Option utilizes a “Point-to-Point” crediting method, the calculation will be based on two Index Values. The Index Change will be calculated using the Index Value on the Term Start Date and Term End Date (unless you exercise a Performance Capture or Lock Threshold is met). The use of a Point-to-Point crediting method results in your Index Credit Rate being calculated at a single point in time, even for a Strategy Account Option with a multi-year Term. |
