What type of document provides information in plain language relevant to investment decisions?

The correct response is Fund Facts, which is specifically designed to present key information about a mutual fund in a clear and straightforward manner. This document is tailored to help investors make informed decisions by summarizing the essential details such as investment objectives, risks, fees, and performance history. The plain language used in Fund Facts is intended to enhance understanding and accessibility for potential investors, ensuring they have the necessary information to compare different investment options effectively.

In contrast, a prospectus can be more detailed and may include complex legal language and extensive data that could be overwhelming for some investors. An information folder typically contains various materials without the specific focus or standardized format that Fund Facts offers. Lastly, a segregated fund contract outlines the terms and conditions of a particular investment product, which may not be as user-friendly as Fund Facts for making quick investment comparisons.
