Des Moines Register: Luana Savings Bank — Iowa’s fifth-largest agricultural lender — is facing financial peril and is accused of committing a massive fraud, according to regulatory and court records. The interrelated allegations against the northeast Iowa-based bank come from the Federal Deposit Insurance Corp. and the Federal Home Loan Bank of Des Moines, a little-known but key player in mortgage financing. In a cease-and-desist order, the FDIC alleges that Luana is taking excessive risks — risks that could under some circumstances lead to the failure of the 113-year-old, family-owned bank, which has three branches in the Des Moines area. Bank President David Schultz said most of its allegations are “manufactured.”
