I'm going to tiptoe around this a bit because there may be a lot of other details or caveats.
This will not fall into a special purpose credit program under 202.8.
Like EmilyAnn said, the fact that you will be extending similar credit to all employees of that large corporation (especially if they are a large business customer, have payroll accounts which bring in a lot of deposits, etc.) may not be an issue. What could be problematic is if there are minority large (or almost as large) companies that are not offered the same benefits/breaks to their employees.
Fair lending is all about consistency - what you do for one you need to do for all. The fact that someone works for a large company has no bearing if they have the character to repay their obligations. (As far as the large company, no credit scenario - every 19 year old new employee starting at Ford is working for a large company and because of the new laws, guaranteed does not have a credit history.)
Rant time - I once heard a loan officer bragging that he was softhearted and gave an underwriting break to a customer. That loan officer and bank in essence just discriminated against similarly situated applicants who were denied because they did not get the same break. I would encourage all to read the American Banker article on August 1 titled "Bankers Fear 'Witch Hunt' in Government's Pursuit of Fair Lending Cases", where American Bankers talks about the DOJ's new fair lending [terrorist] task force. There were more referrals in the past year than cumulatively over the past 20 years. I wouldn't want to take the risk and jepordize the bank.
My opinions.
