Additionally, the Company's loan portfolio is concentrated in commercial business loans, which include commercial and industrial, owner-occupied and nonowner-occupied CRE, and real estate construction and land development loans which include commercial and multifamily real estate construction and land development loans. Commercial business loans and commercial and multifamily real estate construction and land development loans are generally considered as having a more inherent risk of default than residential real estate loans or other consumer loans. Also, the loan balance per borrower is typically larger than that for residential real estate loans and consumer loans, implying higher potential losses on an individual loan basis.</span></div>
