SUMMIT BANCSHARES INC/CA

Summit Bancshares Inc/CA operates as a California-based state commercial bank offering deposit services, commercial lending, cash management, and treasury concierge work for small to mid-sized businesses and professional households across the West Coast, leveraging a focused state-chartered, SIC 6021-style footprint to deliver personalized banking solutions. The franchise balances retail and commercial lending, with its core offerings including checking/savings accounts, certificate of deposit instruments, and relationship-based term and working capital loans tailored to firms seeking local decision-making and fast turnaround. Management pitches itself as a partner for entrepreneurs and professional services providers who value the stability of a regulated bank that still understands regional market dynamics, while also positioning its investment services and trust administration as extensions of that relationship model. Material risks tied to interest-rate volatility, credit losses, deposit concentration shifts, mandated capital ratios, and the evolving state and federal banking oversight that govern the institution keep compliance teams vigilant, especially when filings such as the Form 10-Q submitted in November 1999 are the latest public transparency touchpoints; CIK 353203 underscores that reporting obligation.
