KMC Inc. is a manufacturer of a high processing power microchips used for gaming computer systems. One of KMC’s largest customers is SPEED Gaming: a company that sells high-powered gaming computers, which was founded by and endorsed by a popular Twitch streamer: “iSLOWSPEED”. SPEED Gaming purchased $40,000 worth of microchips from KMC Inc. on 06/01/2025. The purchase was made on a financing plan: with $10,000 being due in four quarterly installments.  The first installment was due on 07/01/2025. However, as of today, the payment has still not been made. Additionally, “iSLOWSPEED” has not been active on his Twitch account, and posted a cryptic message saying “he will no longer be posting any new gaming content or selling any SPEED Gaming equipment.” As a result, KMC Inc. now has significant doubt they will be able to collect the $40,000 that was sold to SPEED Gaming on credit.  Which of the following identification methods would have helped identify this risk to KMC Inc.?
