FIRST OAK BROOK BANCSHARES INC

FIRST OAK BROOK BANCSHARES INC, a State Commercial Bank under SIC 6021, centers its strategy on traditional deposit-taking, commercial lending, and treasury management solutions tailored to small and midsize businesses and affluent local residents seeking personalized banking services. The company’s steady emphasis on core products like checking, savings, and term loans is framed within the regulatory rigor that governs state-chartered institutions, forcing close alignment with capital adequacy standards, liquidity monitoring, and consumer protection rules administered by state and federal agencies. As a regional player deeply reliant on the economic health of its Illinois footprint, it must manage interest-rate sensitivity in its loan and investment portfolios alongside concentration risk stemming from limited geographic diversification. With the most recent disclosure being a Form 10-Q filed in November 1999, investors should watch for modern transparency in quarterly reporting while considering ongoing compliance demands.
