Andy - the 18 point font is in the latest revision to Reg Z and became effective Oct. 1, 2001.
See § 226.5a Credit and charge card applications and solicitations. Specifically, 226.5a (b)(1) Annual percentage rate. Each periodic rate that may be used to compute the finance charge on an outstanding balance for purchases, a cash advance, or a balance transfer, expressed as an annual percentage rate (as determined by § 226.14(b)). When more than one rate applies for a category of transactions, the range of balances to which each rate is applicable shall also be disclosed. The annual percentage rate for purchases disclosed pursuant to this paragraph shall be in at least 18-point type, except for the following: a temporary initial rate that is lower than the rate that will apply after the temporary rate expires, and a penalty rate that will apply upon the occurrence of one or more specific events.
As far as I know, the only part of Reg Z that would apply to business credit is 226.12 which deals with unsolicited issuance of a credit card and liability for unauthorized use. If 10 or more cards are issued for one organization, you may contractually agree on liability for unauthorized use, however the liability may not be posed on an employee either by the issuer or the employer.
So the short answer would be: The 18 point font is required for consumer credit cards. No Reg Z disclosure is required for business credit cards. Or at least, we don't have any Reg Z disclosure for our business credit cards!
This is one area where Reg Z differs from Reg E. Under Reg E, a business account does not have the same protection for errors and unauthorized use. Under Reg Z, they do.
