Personal Savings Account Data Format 2) AMERICAN EXPRESS CARD ACCOUNT ORGANIZATION Every American Express credit and charge card has a unique fifteen-digit number (“Card Number”). The first eleven digits of this number identify the credit card account (“Card Member Account”) to which this card belongs. For each Card Member Account there is a primary card member who is responsible for paying the balance on all of the supplemental cards associated 5/14/2019 AXP Restricted Page | of 9 EFTA00030207

with the account. Up to 99 supplemental cards may be associated with a single account. Ifa primary card member has 10 supplemental cards, all 11 cards would have the same first 11 numbers. The last four digits of the 11 respective card accounts would be different. 3) CARD DATA FORMAT (EXCEL SPREADSHEET TABS) For investigation purposes only, the Financial Intelligence Unit divides internal data on card members into several major categories: Demographic Information (“Demo”), Address, Telephone, Record of Charges (“ROC”), Payment, Wire Payments, Returned Payment, Airline, and IP Address. This data is displayed in the accompanying Excel spreadsheets with each category occupying its own tab. Within each tab, the relevant information is organized by labeled columns. If there is no information to report in a particular category, the tab will simply not appear on the spreadsheet. A general overview of the information within each tab is provided below. A. DEMO The Demo tab identifies account details and demographic information for both charge and/or credit card accounts, listing (where available) the cardholder’s name, date of birth, and social security number as well as information about the particular credit card product (Gold, Platinum, etc.). B. ADDRESS The Address tab identifies all the addresses that have been associated with each credit card and identifies the type of address (home, business, etc.). C. TELEPHONE The Telephone tab identifies all the telephone numbers that have been associated with each credit card and identifies the type of number (Home, Business, ANI). An ANI number is a phone number from which the card member or another individual called an American Express customer service center about the subject account. The number is captured automatically and the date on which the call was made is provided. D. ROC (Record of Charges or Spend) The ROC tab identifies all completed charges (including credits/returns) a credit card has made over the past five years. The tab identifies the date and amount, in U.S. Dollars, of the charge. In addition, the tab identifies the merchant at which the charge was made (the unique merchant account number, legal and d/b/a name as well as address and industry type). E. AUTHORIZATION REQUEST (“CAS” The CAS tab identifies all the credit requests a credit card has made over the past one year. Every time a card is swiped or keyed into a card reader, a request for credit is sent to American Express and an approval code is returned. The request may be approved, denied, or pended. It is important to remember that while 90% of all credit requests are charged exactly as requested, some credit requests are not charged in the same amount or on the same day. For example, when booking a hotel room for four nights, your credit card is swiped and the amount of a four-night §/14/2019 AXP Restricted Page 2 of 9 EFTA00030208

--=PAGE_BREAK=--

stay is requested; however, your card is not charged at that time but rather at the time of check- out, at which time your bill might be for more or less than the original credit request. This tab also identifies whether the payment attempt was made by swiping or keying the card (keying includes internet and phone charges). F. PAYMENT The Payment tab identifies all the payments that have been made against a credit card balance, including dates and amounts, and (where available) information on the bank account on which the payment was drawn. G. RETURNED PAYMENT The Returned Payment tab identifies payments that have been posted against a credit card balance and subsequently returned to the payment source. H. AIRLINE The Airline tab identifies airline ticket charges incurred on a credit card account and contains information provided at the time of purchase, including the passenger’s name, departure date, origin airport, and destination airport. Connecting flight information, if applicable, is generally available in the “Itinerary” column. I. IP ADDRESS The IP Address tab identifies internet protocol address information captured by American Express systems during online account activity (including some purchases, payments, and account changes). If an e-mail was sent through the American Express website, the e-mail and the IP address from which the customer logged in may have been captured. If a customer purchased an item online using an American Express card and provided the merchant with an e- mail address as the point of contact, that address may also appear in this tab. 4) PREPAID CARD ACCOUNT ORGANIZATION Every American Express prepaid card has a unique fifteen-digit number (“Card Number” or “CM15”). Reloadable prepaid card products allow a cardholder to add funds to the account, and some may be used to make ATM withdrawals, transfer money, and write checks. Prepaid card products also include gift cards, which are predenominated and not reloadable. Some prepaid products offer sub-accounts, which are established under the primarily, or “master” account for another person age 13 or older. The sub-account is linked to, funded by, and controlled by the master accountholder. 5) RELOADABLE PREPAID DATA FORMAT (EXCEL SPREADSHEET TABS) For investigation purposes only, the Financial Intelligence Unit divides internal data on prepaid members into several major categories: Demographic Information (“Demo”), Address, Telephone, Peer to Peer Transactions (“P2P”), IP Address, Card Transactions, BillPay Transactions, Airline Transactions, Funds Load, Withdrawals, Disputes, and Customer Service Notes. §/14/2019 AXP Restricted Page 3 of 9 EFTA00030209

The Financial Intelligence Unit divides internal data on other prepaid card members into several major categories: Sale Info, Demographic Information (“Demo”), Redemptions (“OR_ REDE”), Authorizations (“OR AUTH”), Web Balance Inquiry (“OR_WEBBAL”), Direct Deposits, IVR Inquiry, and Airlines. This data is displayed in the accompanying Excel spreadsheets with each category occupying its own tab. Within each tab, the relevant information is organized by labeled columns.

A. DEMO The Demo tab for prepaid accounts associates an account with an individual, listing (where available) their name, date of birth, social security number, and email address, as well as information about the specific product, account status, and account type (Master, Sub, or PurposeDriven (a savings account, which is linked to a master account)). B. ADDRESS The Address tab identifies all addresses that have been associated with each account, and identifies the type of address (home, business, etc.). C. TELEPHONE The Telephone tab identifies all telephone numbers that have been associated with each account, and identifies the type of number (Home, Mobile, Business, ANI, etc.). An ANI number is a phone number from which the card member called an American Express customer service center. The number is captured automatically and the date on which the call was made is provided. D. P2P The P2P tab provides information on all P2P transfers (transfers between prepaid accounts) sent and received by a particular prepaid account, including account information for all senders and recipients. E. IP The IP Address tab identifies internet protocol address information captured by American Express systems during online account activity. F.

I. FUNDS LOAD The Funds Load tab provides information on when, where, and how a prepaid account was funded (e.g. cash, direct deposit, credit/debit card load, etc.). Note — because in some instances the data is maintained by a third party, some credits labeled “cash” may not actually have been made via cash payment. For additional questions, please reach out to the Financial Intelligence Unit. J. WITHDRAWALS The Withdrawals tab provides information on money withdrawn from a prepaid account via check or ACH transfer, including the date, transaction amount, and transaction status, as well as the bank name, account number, and routing number (where applicable). K. DISPUTES The Disputes tab includes information on transactions disputed by the prepaid accountholder, including the dispute date, amount, reason, and resolution. L. CUSTOMER SERVICE NOTES The Customer Service Notes tab consists of notes recorded by customer service representatives, and often includes information regarding customer phone calls, promotional offers, changes to demographic information, and changes in account status. 6) PREPAID GIFT CARDS DATA FORMAT (EXCEL SPREADSHEET TABS) A. DEMO The Demo tab for prepaid gift cards associates a prepaid card with an individual, and may, in limited circumstances, list their name, date of birth, social security number, address, phone number, and email address, as well as information about the product type (e.g. reloadable or single load) and the card status. B. SALE INFO The Sale Info tab explains when and where each prepaid card was purchased, as well the original load value. C. TRANSACTIONS The Transactions tab identifies transactions conducted using a prepaid card, including purchases, refunds, value loads, promotional credits, and maintenance fees. When money is added to a prepaid card, the amount will appear under “redeem amount” as a negative number (for example, a value load of $500.00 would be notated as -$500.00). §/14/2019 AXP Restricted Page 5 of 9 EFTA00030211

G. AIRLINES The Airline tab identifies airline ticket charges and contains information provided at the time of purchase relating to the departure date, originating airport, destination airport, and passenger names. 7) AMERICAN EXPRESS MERCHANT ACCOUNT ORGANIZATION Merchant accounts are established for businesses that accept American Express cards, and each established merchant account is issued a unique ten-digit number (“merchant account number” or “SE10”). Please note that “SE” is frequently used as a synonym for “merchant”; SE stands for “Service Establishment.” Merchant accounts are associated with an authorized signer and a corresponding bank account. The authorized signer serves as the point of contact for the merchant account, and that individual’s identifying information is stored in internal American Express systems, along with the bank account number provided to American Express at account opening.! 8) MERCHANT DATA FORMAT (EXCEL SPREADSHEET TABS) For investigation purposes only, the Financial Intelligence Unit divides internal data on merchant accounts into several major categories: Demographic Information (“SE Demo”), Record of Charges (“SE ROC”), Authorization Request (“SE CAS”), Merchant Fraud (“SE Fraud”), Merchant Billed ROC (“SE Billed Roc”), Merchant IP (“SE IP”), and Merchant Disputes (“SE Disputes”). This data is displayed in the accompanying Excel spreadsheet with each category occupying its own tab. Within each tab, the relevant information is organized by labeled columns. If there is no information to report in a particular category, then the tab will simply not appear on the spreadsheet. A general overview of the information within each tab is provided below. ' The availability of bank account information varies for international merchants. §/14/2019 AXP Restricted Page 6 of 9 EFTA00030212

--=PAGE_BREAK=--

A. MERCHANT DEMO (SE DEMO) The Merchant Demo tab lists the unique merchant account number, the legal name of the business, as well as a Doing Business As name (where available). In cases where the merchant relationship is not proprietary (i.e., a Seller or Location merchant), additional merchant data will be provided in the tab. If the merchant is a Seller Merchant (that is, a third-party merchant account that contracts with an “aggregator merchant” that contracts directly with American Express to bring merchants to the American Express network), then “Seller” will appear under the “Searched Merchant Type” field. If the merchant is a sub-merchant (i.e., acquired under a third party payment processor such as Paypal or Square), then “Location” will appear under the “Searched Merchant Type.” The Merchant Demo tab also provides the reported address and telephone number for the business, as well as the name and social security number of the authorized signer(s) on the account. This tab further provides a correspondence address for the business, a general industry description of the business, and an indication of whether the account is open or closed.?_ Finally, the bank account number (if available based on merchant type*) and corresponding routing number for each merchant account is listed in the last column to the right in the Merchant Demo tab of each spreadsheet. B. MERCHANT ROC (SE_ROC —- RECORD OF CHARGES OR SPEND AT THE MERCHANT) The Merchant ROC (“Record of Charge”) tab identifies all completed American Express charges processed by the merchant. The tab identifies the timestamp and amount, in U.S. dollars as well as the local amount (if outside of the U.S.) of each charge processed by the merchant. In addition, the tab lists the card number and the name of the cardholder that made the purchase, as well as some demographic information regarding that cardholder and card (including, but not limited to, the cardholder’s name, the card type and issuer). C. MERCHANT AUTHORIZATION REQUEST (SE_CAS) This tab lists all credit authorizations sent by the merchant over the past two years. Every time a card is swiped or keyed into a card reader, a request for credit is sent to American Express and an approval code is returned. The request may be approved, denied, or pended. This tab identifies whether the merchant processed the transaction by swiping or keying the card (keying includes internet and phone charges, while swiping typically indicates that the cardholder was physically present at the merchant at the time of the transaction). D. MERCHANT FRAUD (SE_ FRAUD) This tab identifies all transactions processed by the merchant that were ultimately reported as fraudulent by a respective American Express cardholder. E. DISPUTES (SE_DISPUTES) The Disputes tab identifies all initiated charge disputes against a given merchant and the status of individual disputes. F. MERCHANT BILLED ROC (SE_ BILLED ROC) ? In the case of Seller and Location merchants, the status information reflects that of the Submitting merchant, and not the sub-merchants. * Bank account information is not available for Seller and Location merchants. §/14/2019 AXP Restricted Page 7 of 9 EFTA00030213

--=PAGE_BREAK=--

The Merchant Billed ROC tab identifies all completed American Express charges processed by the merchant over the past five years. The tab identifies the date and amount, in U.S. dollars, of each charge processed by the merchant. In addition, the tab identifies the date and amount of the transaction, the card number and the name of the cardholder that made the purchase, as well as information regarding that cardholder (In the case of the merchant accounts pulled for the Texas Attorney General’s Office, please note that due to the size of some of the spreadsheets, the BILLED ROC tab was not included. The majority of transactions will appear in the ROC tab). G. IP ADDRESS (SE _ IP) The IP tab identifies internet protocol address information captured by American Express systems during online account activity. 9) PERSONAL SAVINGS ACCOUNT ORGANIZATION American Express National Bank issues High-Yield Savings accounts (“HYSAs”) and Certificates of Deposit (“CDs”) to individuals. HYSAs and CDs are both referred to as Personal Savings Accounts (“PSAs”). Every PSA has a unique ten-digit or twelve-digit account number and may have up to two account holders — a primary account holder and a secondary account holder. Each account holder has a unique customer identification number (“Customer ID”) and has equal access to the PSA. 10) PERSONAL SAVINGS ACCOUNT DATA FORMAT (EXCEL SPREADSHEET TABS) For investigation purposes only, the Financial Intelligence Unit divides internal data on PSA account holders into several major categories: Demographic Information (“Demo”), Address, Notes, Stop-Holds, Transactions, IP Address, and Linked Accounts. This data is displayed in the accompanying Excel spreadsheets with each category occupying its own tab. Within each tab, the relevant information is organized by labeled columns. If there is no information to report in a particular category, the tab will either be blank or not appear on the spreadsheet. A general overview of the information within each tab is provided below. A.

LINKED ACCOUNTS The Linked Accounts tab includes information for external bank accounts currently or previously linked to the PSA(s), including the routing number and bank account number. Each account holder is authorized to link up to three external bank accounts to their PSA(s). Of note the column “Expiration Date” identifies the date any test transactions are to be conducted for verification purposes. Further, the column “Bank Name” displays the account name as chosen by the account holder for their own recordkeeping purposes. §/14/2019 AXP Restricted Page 9 of 9 EFTA00030215
