Affiliate Marketing Secrets

I have already submitted an application, and just got a letter in the mail today with the brochere and a personal information release form for them to conduct a records search on me. Can someone tell me what exactly will be searched, and if they can get information on all reports that have my name on them? I know my crimminal record check has come back clean with no offences listed on it, as I got one done for employment purposes about a month ago. I’m just wondering if that’s all that will be searched, and what CPIC, CNI, NICHE, ARCHIVED, and MTO all are, as they are in a chart on my personal release form to be checked off as negative (clean).
