Which of the following is a required disclosure under the Truth in Savings Act?

The correct answer is the methods for calculating APY, as this is a specific requirement under the Truth in Savings Act (TISA). The regulation mandates financial institutions to disclose the Annual Percentage Yield (APY) in a manner that allows consumers to understand the potential earnings on their accounts clearly. Providing information about the methodology used to calculate APY helps ensure transparency and enables consumers to make informed comparisons between different savings products.

In terms of the other choices, while minimum balance requirements can be important information, they are not explicitly categorized as required disclosures under TISA for all account types. Credit card interest rates related to accounts fall outside the scope of TISA, which primarily deals with deposits and savings accounts rather than credit products. Lastly, while a full list of branch locations may be helpful supplementary information for consumers, it is not considered a disclosure required under the TISA framework.
