The rendering log information below will not appear on the EDGAR web site.
Warning: [rq-1206-Multiple-Root-Nodes] Presentation group Risk/Return Detail Data has multiple root nodes. XBRL allows unordered root nodes, but rendering requires ordering. They will instead be ordered by their labels. To avoid undesirable ordering of axes and primary items across multiple root nodes, rearrange the presentation relationships to have only a single root node.
