What information is NOT required on periodic statements for open-end credit according to Reg Z?

The correct answer pertains to the information that is not mandated to be included on periodic statements for open-end credit accounts under Regulation Z. Specifically, while Regulation Z requires certain disclosures to be made on these statements, the specification regarding the credit limit on the account is not one of them.

Periodic statements must include essential details such as the previous balance and new balance, a breakdown of transactions conducted during the billing cycle, and the annual percentage rate along with the finance charges that apply. These elements are crucial for consumers to understand their current financial status, track their spending, and know how much interest they are accruing.

On the other hand, although knowing the credit limit can be helpful for consumers, it is not a required item on the periodic statement. The aim of Regulation Z is to ensure transparency in lending and allow consumers to make informed decisions. The absence of the credit limit on these statements does not impede this goal, as the necessary information for managing open-end credit is still comprehensively covered by the required disclosures.
