3.3 Truth in Savings: Account Disclosures and APY

---

Truth in Savings Act (Regulation DD) Core Requirements

Regulation DD applies to deposit accounts held at depository institutions by or on behalf of a natural person primarily for personal, family, or household purposes. It specifically excludes commercial, partnership, corporate, and governmental accounts.

Account Opening Disclosures (12 CFR § 1030.4)

Depository institutions must provide full account disclosures prior to account opening or before a deposit service is rendered. If an account is opened without the consumer being present in person (e.g., via telephone or mail), disclosures must be mailed or delivered within 10 business days. Required disclosures include:

• Rate Information: The annual interest rate and the Annual Percentage Yield (APY), calculated in accordance with Appendix A of Regulation DD. For variable-rate accounts, the disclosure must specify that the rate and APY may change, how the rate is determined, the frequency of changes, and any limitations.
• Compounding and Crediting: The frequency with which interest is compounded and credited to the account.
• Minimum Balance Rules: Minimum deposit required to open the account, minimum balance required to avoid maintenance fees, and minimum balance required to earn the stated APY.
• Balance Computation Method: Depository institutions are legally restricted to two permissible calculation methods under 12 CFR § 1030.7:
  1. Daily Balance Method: Applying a daily periodic rate to the full principal balance in the account each day.
  2. Average Daily Balance Method: Applying a periodic rate to the average daily balance calculated by dividing the sum of the daily balances during the cycle by the number of days in the cycle.

  Warning

  Statutory Prohibition: The historical minimum balance method (paying interest only on the lowest balance recorded during the entire statement period) is strictly unlawful under 12 CFR § 1030.7(a)(1).

• Accrual of Interest: Disclosing when interest begins to accrue on noncash deposits (checks). By law, interest must begin accruing no later than the business day on which the institution receives provisional credit under Regulation CC schedules.
• Fee Schedules: An itemized schedule of all fees that may be assessed in connection with the account, including maintenance, transaction, stop-payment, wire, and overdraft/NSF charges.
• Transaction Limitations: Any limits on deposit or withdrawal amounts, frequencies, or transfer methods.
• Time Deposit (CD) Terms: Maturity dates, call provisions, grace periods, early withdrawal penalties, and automatic renewal terms.

Change in Terms Notice (12 CFR § 1030.5)

Financial institutions must provide written or electronic notice at least 30 calendar days prior to the effective date of any change in terms that:

• Adversely affects the consumer; or
• Reduces the Annual Percentage Yield (APY) earned on the account.

Exceptions to Advance Notice: Advance notice is not required for:

• Reductions in APY on variable-rate deposit accounts (where interest rates change based on market indices or internal formulas disclosed at opening);
• Changes in fees assessed for third-party check printing; or
• Changes in terms for time accounts with a maturity of one month or less.

Deposit Advertising Standards (12 CFR § 1030.8)

Regulation DD establishes strict truth-in-advertising principles:

• Trigger Terms: If an advertisement states an interest rate, it must state the rate as an Annual Percentage Yield (APY) using that exact phrase. The nominal interest rate may be stated, but only if the APY is stated at least as conspicuously.
• Free Account Restrictions: An institution may never advertise an account as "free" or "no-cost" (or similar wording) if the account imposes any monthly maintenance fee, minimum balance fee, or transaction activity fee. Even if the maintenance fee is waivable based on direct deposit or minimum balance, advertising the account as "free" constitutes a per se violation of § 1030.8(a).
• Misleading Practices: Advertisements must not be misleading or misstate the terms of the deposit agreement.

Overdraft Regulatory Architecture: Regulation E Opt-In (§ 1005.17)

The assessment of overdraft fees on electronic debit transactions is governed by the affirmative consent rules of Regulation E.

The Mandatory Opt-In Rule

Under 12 CFR § 1005.17(b)(1), a depository institution shall not assess a fee or charge on a consumer's account for paying an automated teller machine (ATM) or one-time debit card transaction pursuant to the institution's overdraft service, unless the institution:

1. Provides the consumer with a segregated written (or E-SIGN compliant electronic) disclosure detailing the overdraft service, substantially similar to Model Form A-9;
2. Provides the consumer a reasonable opportunity to affirmatively consent (opt in);
3. Obtains the consumer's affirmative consent (opt-in); and
4. Delivers written confirmation of the consent, including a clear notice reminding the consumer of their legal right to revoke consent at any time.

Covered vs. Exempt Overdraft Transactions

Compliance managers must enforce strict operational boundaries between transaction categories:
