Which statement must be included if "Annual Percentage Yield" is advertised?

When "Annual Percentage Yield" (APY) is advertised, it is critical to include that the interest rate may change if it is variable. This reflects the requirement under the Truth in Savings Act, which mandates that any advertisement of APY must also convey relevant information regarding the nature of the interest rate that applies to the account.

If an account has a variable interest rate, this means that the APY is not guaranteed to remain unchanged over time; instead, it can fluctuate based on market conditions or the institution's policies. By specifying that the interest rate may change, consumers are given a clearer understanding of how their potential earnings can vary, which is essential information for making informed financial decisions.

The other statements do not provide relevant information tied to the requirements for advertising APY. For instance, saying that the APY will remain constant does not apply in case of variable rates; claiming that accounts must be opened in person is unrelated to the nature of the advertised APY; and stating that the APY is available for all accounts is misleading, as not all accounts may qualify for the same APY. Including the possibility of a change in the interest rate ensures transparency and compliance with TISA regulations.
