Operates a Wisconsin community bank that earns primarily the spread between lending and funding costs, alongside mortgage, account-service and cash-management income. Its concentrated real-estate loan book and five-office Wisconsin footprint link results to local property conditions, deposit pricing and wholesale funding.
Runs a five-office Wisconsin community-banking franchise through Marathon Bank, serving Wausau-area markets and the Milwaukee-area counties of Ozaukee and Waukesha. Its product set spans commercial and multifamily real-estate credit, residential mortgages, personal lending, deposit accounts and specialty banking for property managers, homeowners' associations, religious organizations and 1031-exchange customers.
Earns primarily the spread between interest on loans and investments and the cost of deposits and borrowings, with mortgage banking, account charges and cash-management services adding non-interest income. Relationship managers and online and mobile banking support customers; the bank generally sells conforming fixed-rate residential mortgages while holding adjustable-rate residential, commercial and multifamily loans.
Maintains a real-estate-concentrated loan portfolio funded by customer deposits, Federal Home Loan Bank advances and brokered deposits. Operations depend on Wisconsin economic and property conditions, deposit retention, interest-rate transmission, wholesale-funding access, and bank-capital and securities rules.
