#Person1#: Mr. Brown! How nice to see you, can I help?
#Person2#: I'm not exactly sure if it's your department, but I'd like to ask some questions about qualifying for Comprehensive Credit Granting.
#Person1#: I see. You are one of my favourite customers, Mr. Brown. I'm more than happy to help. For Comprehensive Credit Granting, IBA will grant a promised quota for you, that is, if you qualify. Of course, your credit record, within you field of trade needs to be up to scratch.
#Person2#: How long a period will you look at to determine this?
#Person1#: We will consider the first part of the year, in your particular field, and your credit rating can be no less than class A, during that period.
#Person2#: That sounds simple enough. It's Friday today, I'll be back on Monday morning, first thing, with all of the relevant data. See you then, and enjoy your weekend.
