An indexed UL multiplier is a non-guaranteed enhancement that increases credited interest by a stated factor (e.g., 1.2) under certain conditions, typically in exchange for an asset charge. Multipliers can amplify index credits in positive periods but also reduce returns when index credits are low and charges persist. They are not guarantees and are subject to product rules and illustration constraints (e.g., AG 49-A). Advisors evaluate multipliers against costs, caps, and participation to determine whether the feature improves long-term efficiency.

Producers evaluate multiplier charges versus historical credits and alternative strategies. If cost outweighs benefit, they may disable the feature or switch allocations; if favorable, they illustrate long-term effects conservatively.
