Performance Narrative [Text Block]

On June 1, 2026, the Fund changed its Underlying Index and certain of its principal investment strategies. Consequently, the Fund’s total returns shown below for the periods prior to June 1, 2026 are not necessarily indicative of the performance of the Fund, as it is currently managed. The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of the Underlying Index and an index that represents a broad measure of market performance. Absent any applicable fee waivers and/or expense reimbursements, performance would have been lower. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Total return figures assume reinvestment of dividends and capital gains distributions and include the effect of the Fund’s recurring expenses. Updated performance information is available online at www.alpsfunds.com or by calling 866.759.5679.
