The S&P Target Date Style indices are designed to help defined contribution plan sponsors screen, select, and monitor appropriate target date funds. The indices assist in determining where particular target date fund families fall on the "to"/"through" spectrum. Based on the S&P Target Date Index, the asset allocation for the S&P Target Date Style Indices is derived from a rigorous annual survey of target date funds. The main survey group is classified into "to" and "through" sub-groups according to a two-factor model.
All information for an index prior to its Launch Date is hypothetical back-tested, not actual performance, based on the index methodology in effect on the Launch Date. Back-tested performance reflects application of an index methodology and selection of index constituents with the benefit of hindsight and knowledge of factors that may have positively affected its performance, cannot account for all financial risk that may affect results and may be considered to reflect survivor/look ahead bias. Actual returns may differ significantly from, and be lower than, back-tested returns. Past performance is not an indication or guarantee of future results. This back-tested data may have been created using a “Backward Data Assumption”. For more information on “Backward Data Assumption” and back-testing in general, please see the Performance Disclosure.
