I work at a large financial institution. We do not file CTRs on aggregated transactions involving our subsiaries (consumer loan, insurance, mortgage providers) nor have we filed an exemption regarding them. Our regulators have never mentioned anything about it (thank goodness if we're wrong). Does anyone file CTRs or exemptions regarding their subsidiaries. When a single transaction in currency is involved, we do file regarding the individual who cashes the loan disembursement check or tries to repay an obligation with cash. I'd love to know what other people are doing.
