12 CFR 226.51 - Ability to Pay.
(a)General rule - (1)(i) Consideration of ability to pay. A card issuer must not open a credit card account for a consumer under an open-end (not home-secured) consumer credit plan, or increase any credit limit applicable to such account, unless the card issuer considers the consumer's independent ability to make the required minimum periodic payments under the terms of the account based on the consumer's income or assets and current obligations.
(ii)Reasonable policies and procedures. Card issuers must establish and maintain reasonable written policies and procedures to consider a consumer's independent income or assets and current obligations. Reasonable policies and procedures to consider a consumer's independent ability to make the required payments include the consideration of at least one of the following: The ratio of debt obligations to income; the ratio of debt obligations to assets; or the income the consumer will have after paying debt obligations. It would be unreasonable for a card issuer to not review any information about a consumer's income, assets, or current obligations, or to issue a credit card to a consumer who does not have any independent income or assets.
(2)Minimum periodic payments -
(i)Reasonable method. For purposes of paragraph (a)(1) of this section, a card issuer must use a reasonable method for estimating the minimum periodic payments the consumer would be required to pay under the terms of the account.
(B) The card issuer uses a minimum payment formula employed by the issuer for the product the issuer is considering offering to the consumer or, in the case of an existing account, the minimum payment formula that currently applies to that account, provided that:
(1) If the applicable minimum payment formula includes interest charges, the card issuer estimates those charges using an interest rate that the issuer is considering offering to the consumer for purchases or, in the case of an existing account, the interest rate that currently applies to purchases; and
(2) If the applicable minimum payment formula includes mandatory fees, the card issuer must assume that such fees have been charged to the account.
(b)Rules affecting young consumers -
(1)Applications from young consumers. A card issuer may not open a credit card account under an open-end (not home-secured) consumer credit plan for a consumer less than 21 years old, unless the consumer has submitted a written application and the card issuer has:
(i) Financial information indicating the consumer has an independent ability to make the required minimum periodic payments on the proposed extension of credit in connection with the account, consistent with paragraph (a) of this section; or
(A) A signed agreement of a cosigner, guarantor, or joint applicant who is at least 21 years old to be either secondarily liable for any debt on the account incurred by the consumer before the consumer has attained the age of 21 or jointly liable with the consumer for any debt on the account, and
(B) Financial information indicating such cosigner, guarantor, or joint applicant has the ability to make the required minimum periodic payments on such debts, consistent with paragraph (a) of this section.
(2)Credit line increases for young consumers. If a credit card account has been opened pursuant to paragraph (b)(1)(ii) of this section, no increase in the credit limit may be made on such account before the consumer attains the age of 21 unless the cosigner, guarantor, or joint accountholder who assumed liability at account opening agrees in writing to assume liability on the increase.
